However, there is an absence of research on how contextual (eg, community/societal) factors interact with pain for these patients. Informed by the socio-ecological model, this study aimed to elucidate the individual, interpersonal, community, and societal factors associated with chronic pain from the perceptions of older adult patients and medical staff in a community clinic.Patients and Methods: In this qualitative study, we conducted four focus groups and two interviews with medical staff (n=25) and three focus groups and seven individual interviews with older adult patients with chronic pain (n=18). Participants were recruited using purposive sampling from an ethnically and economically diverse primary care clinic in the greater Boston community. We transcribed assessments and thematically analyzed data using a hybrid deductive-inductive approach.Results: At the individual level, we identified three themes: (1) older adults with complex care needs, (2) impact of pain (including on physical, emotional, work, and identity functioning), and (3) coping with pain. At the interpersonal level, complex relationships with (1) social supports and (2) medical staff emerged as themes. The need for (1) resources and (2) culturally informed care was identified at the community level, and socioeconomic status impacting the availability of resources for managing chronic pain emerged for the societal domain.Conclusion: Findings underscore the intersection of factors contributing to the experience of pain among older adults from underserved communities. Our findings highlight the need to develop and implement treatments that fully address the experience of older adults with chronic pain at the individual, interpersonal, community, and societal levels.Keywords: community clinic, pain, health disparities

Abstract Angiogenesis-osteogenesis coupling is critical for proper functioning and maintaining the health of bones. Any disruption in this coupling, associated with aging and disease, might lead to loss of bone mass. Osteoporosis (OP) is a debilitating bone metabolic disorder that affects the microarchitecture of bones, gradually leading to fracture. Computational analysis revealed that normal angiogenesis is disrupted during the progression of OP, especially postmenopausal osteoporosis (PMOP). The genes associated with OP and PMOP were retrieved from the DisGeNET database. Hub gene analysis and molecular pathway enrichment were performed via the Cytoscape plugins STRING, MCODE, CytoHubba, ClueGO and the web-based tool Enrichr. Twenty-eight (28) hub genes were identified, eight of which were transcription factors (HIF1A, JUN, TP53, ESR1, MYC, PPARG, RUNX2 and SOX9). Analysis of SNPs associated with hub genes via the gnomAD, I-Mutant2.0, MUpro, ConSurf and COACH servers revealed the substitution F201L in IL6 as the most deleterious. The IL6 protein was modeled in the SWISS-MODEL server and the substitution was analyzed via the YASARA FoldX plugin. A positive ΔΔG (1.936) of the F201L mutant indicates that the mutated structure is less stable than the wild-type structure is. Thirteen hub genes, including IL6 and the enriched molecular pathways were found to be profoundly involved in angiogenesis/endothelial function and immune signaling. Mechanical loading of bones through weight-bearing exercises can activate osteoblasts via mechanotransduction leading to increased bone formation. The present study suggests proper mechanical loading of bone as a preventive strategy for PMOP, by which angiogenesis and the immune status of the bone can be maintained. This in silico analysis could be used to understand the molecular etiology of OP and to develop novel therapeutic approaches.

As research on the determinants of MSP is evolving, biomarkers can probably play a significant role in understanding its causes and improving its clinical management. This scoping review aimed to provide an overview of the associations between biomarkers and MSP.Methods: This study followed Arksey and O’Malley and PRISMA-ScR recommendations. Keywords related to biomarkers, association, and MSP were searched on PubMed, Embase, Cochrane, and Web of Science databases from inception to September 28th, 2023. Data were systematically retrieved from the retained articles. A narrative synthesis approach – but no quality assessment – was used to map the core themes of biological markers of MSP that emerged from this work.Results: In total, 81 out of 25,165 identified articles were included in this scoping review. These studies were heterogeneous in many aspects. Overall, vitamin D deficiency, dyslipidemia (or hypercholesterolemia), and cytokines (high levels) were the most studied biomarkers with regards to MSP and were most often reported to be associated with non-specific MSP. Cadmium, calcium, C-reactive protein, collagen, creatinine, hormones, omega-3 fatty acids, sodium, tumor necrosis factor-alpha, and vitamin C were also reported to be associated with MSP syndromes, but the evidence on these associations was sketchier. No conclusions could be drawn as to age and sex.Conclusions: Our findings suggest that some biomarkers are associated with specific MSP syndromes, while others would be associated with non-specific syndromes. Among all candidate markers, the evidence seems to be more consistent for vitamin D, cytokines and lipids (total cholesterol, triglycerides, low- and high-density lipoproteins). High-quality studies, stratified by age and sex, are needed to advance our understanding on biomarkers of MSP.Keywords: musculoskeletal pain, biomarkers, scoping review

The diagnosis of diabetes mellitus was made according to the criteria of the American Diabetes Association. The diagnosis of AHF is established by the signs and symptoms of heart failure; increased levels of brain natriuretic peptide (BNP); and systolic and/or diastolic dysfunction on echocardiography.Results: 63 T2DM and 120 non-T2DM consecutive patients were selected. Age (≥ 50 years in men and ≥ 60 years in women) (OR=2.08 [1.31– 5.14]), dyslipidemia (OR=3.95 [1.82– 8.75]), microalbuminuria (OR=6.06 [1.69– 27.3]) and overweight/obesity (OR=3.32 [1.33– 13.5]) were more frequent in T2DM. The clinical profile of T2DM was marked by the rise in mean systolic arterial pressure (p=0.0368), arterial oxygen desaturation (p=0.0214), New York Heart Association (NYHA) IV breathlessness (OR=2.06 [1.04– 4.08]); and paraclinical by left ventricular hypertrophy (OR=2.67 [1.24– 5.77]), segmental kinetic disorder (OR=1.96 [1.04– 3.67]) and ischemic heart disease (OR=1.98 [1.09– 3.92]). Diabetics received more statin (OR=2.06 [1.05– 4.03]) and less spironolactone (OR=0.29 [0.13– 0.64]).Conclusion: T2DM is associated with poor profile of AHF. Adequate management of cardiovascular risk factors, including diabetes, could thus minimize the occurrence of AHF and improve this profile.Keywords: acute heart failure, cardiovascular risk factors, coronary artery disease, Madagascar, type 2 diabetes mellitus

The study aimed to evaluate antimicrobial susceptibility patterns and MRSA exhibiting multidrug resistance obtained through a microbiological culture of clinical specimens at Bac Ninh Provincial General Hospital in Bac Ninh Province, Vietnam.Methods: We employed a cross-sectional analysis at Bac Ninh Provincial General Hospital in Vietnam. 15,232 clinical samples from inpatients were examined. S. aureus isolates were identified using established protocols and tested for MRSA and antibiotic susceptibility. Data was analyzed using R software, with statistical calculations to assess associations between variables.Results: Staphylococcus aureus was isolated from 417 samples (2.7%), with 77.2% being MRSA and 22.8% methicillin-susceptible Staphylococcus aureus (MSSA). Significant sources of MRSA were wounds (64.6%) and the surgical unit (50%) according to sample types and hospital wards, respectively. S. aureus showed high resistance rates, the highest being azithromycin (83.2%), and was fully susceptible to vancomycin. Among 294 multidrug-resistant (MDR) strains, the prevalence was 82.0% in MRSA and 18.0% in MSSA.Conclusion: The study highlights widespread antimicrobial resistance among MRSA isolates from a provincial hospital in Vietnam, emphasizing the urgent need for antibiotic surveillance, formulation of antibiotic policies, and preventive measures to tackle the increasing prevalence of multidrug-resistant MRSA.Keywords: Staphylococcus aureus, antibiotic resistance, MRSA, MDR, Vietnam

Objective To develop and optimise an app (iMPAKT) for improving implementation and measurement of person-centred practice in healthcare settings. Methods Two iterative rounds of testing were carried out based on cognitive task analysis and qualitative interview methods. The System Usability Scale (SUS) was also used to evaluate the app. Quantitative data on task completion and SUS scores were evaluated descriptively, with thematic analysis performed on qualitative data. The MoSCoW prioritisation system was used to identify key modifications to improve the app. Results Twelve participants took part (eight health professionals and four patient and public involvement representatives). Views on design and structure of the app were positive. The majority of the 16 tasks undertaken during the cognitive task analysis were easy to complete. Mean SUS scores were 73.5/100 (SD: 7.9; range = 60–92.5), suggesting good overall usability. For one section of the app that transcribes patients speaking about their experience of care, a non-intuitive user interface and lack of transcription accuracy were identified as key issues influencing usability and acceptability. Conclusions Findings from the evaluation were used to inform iterative modifications to further develop and optimise the iMPAKT App. These included improved navigational flow, and implementation of an updated artificial intelligence (AI) based Speech-To-Text software; allowing for more accurate, real-time transcription. Use of such AI-based software represents an interesting area that requires further evaluation. This is particularly apparent in relation to potential for large-scale collection of data on person-centred measures using the iMPAKT App, and for assessing initiatives designed to improve patient experience.

Objetivos: Relatar caso de anemia hemolítica autoimune (AHAI) por anticorpos frios associada a Leucemia Linfoblástica Aguda B (LLA-B). Resultados: Paciente feminina, 53 anos, com antecedente de câncer de mama curado, apresentou-se em setembro/2023 com equimoses espontâneas e sintomas gripais que haviam iniciado na semana anterior. Hemograma mostrou anemia (Hb 11,4 g/dL), leucocitose (26400/μL), linfocitose (16100/μL) e plaquetopenia (20000/mm3). O mielograma apresentou 57% de blastos, compatível com LLA-B comum. A pesquisa da translocação BCR::ABL foi negativa. Iniciada indução quimioterápica com prednisona, metotrexato, dexametasona, vincristina e daunorrubicina. Durante o tratamento, intercorreu com disfunção hepática após pegasparaginase em outubro/2023, pneumonia em novembro/2023 e neutropenia febril em dezembro/2023. Em fevereiro/2024, foi reinternada devido fadiga, vômitos, diarreia e febre. Exames evidenciaram anemia intensa (Hb 4,2 g/dL) e plaquetopenia moderada (82.000/mm3), em associação a coombs direto positivo (C3d positivo, eluato negativo) sugerindo doença da aglutinina a frio, embora houvesse reticulocitopenia. Estudo imunohematologico foi realizado em mais de uma ocasião e consistentemente mostrava anticorpos anti-IgM com especificidade anti-I em título maior que 1/64. Prosseguiu-se com investigação de diagnósticos diferenciais que evidenciou infecção pelo citomegalovírus, com carga viral de 682 cópias. Assim, apesar de sintomatologia gastrointestinal frustra e da ausência de anatomopatológico confirmatório, foi iniciado tratamento empírico com ganciclovir, mas não houve melhora da anemia. Exames medulares imediatamente antes e logo após o aparecimento da anemia evidenciaram doença residual mensurável negativa (DRM). Dessa forma, optou-se por realizar modalidades de tratamento focadas na AHAI (Prednisona, Azatioprina, Rituximabe e Bortezomibe), mas, sem resposta. A paciente manteve anemia intensa (hemoglobina abaixo de 6 g/dL), necessitando de transfusões sanguíneas com concentrados de hemácias aquecidos para melhor rendimento. Sendo assim, deu-se seguimento ao tratamento da LLA e a paciente foi encaminhada para o transplante de medula alogênico haplo-idêntico em maio/2024. Evoluiu com com síndrome veno oclusiva e faleceu no 8º dia após o transplante. Discussão: A doença da crioaglutinina caracteriza-se por AHAI causada por anticorpos monoclonais a frio com títulos iguais ou maiores que 1/64. Frequentemente apresenta-se em associação a Linfomas B, embora possa ser identificada em pacientes com evidência de população clonal de linfócitos, mas sem sinais radiológicos ou clínicos de malignidade. Sua identificação em concomitância à LLA é extremamente infrequente. Torna o caso ainda mais intrigante a ausência de doença detectável no momento do aparecimento da AHAI, vistos os estudos medulares mostrando DRM negativa. Realça-se ainda a gravidade da manifestação, visto a manutenção de anemia grave, durante 3 meses, apesar dos múltiplos tratamentos realizados. Apenas cerca de 27% dos casos de doença da crioaglutinina apresentam-se com hemoglobina abaixo de 8, embora o quadro possa ser exacerbado durante quadros inflamatórios/infecciosos agudos devido à ativação do complemento. Conclusão: O caso evidencia uma apresentação atípica da doença da aglutinina a frio associada, também de forma infrequente, a LLA-B, evidenciando a necessidade de avançarmos em nosso entendimento de ambas as doenças e etiopatogenias.

Introdução: A microangiopatia trombótica associada ao câncer é um tipo raro de anemia hemolítica Coombs negativa e apresenta prognóstico muito desfavorável. Caso clínico: Apresentamos o caso de uma paciente do sexo feminino, de 59 anos, admitida com quadro de fraqueza, hiporexia, náusea e perda ponderal de 10 Kg em aproximadamente 06 meses. A avaliação laboratorial inicial demonstrou uma anemia grave, com hemoglobina de 2,5 g/dL, normocítica e normocrômica, associada à plaquetopenia grave, além de achados de leucoeritroblastose e esquizócitos / dacriócitos em sangue periférico. Observada ainda desidrogenase lática de 3360 U/L (valor de referência até 246 U/L), haptoglobina de 1 mg/dL, bilirrubina indireta de 0,74 mg/dL e reticulócitos de 12,3% (corrigido: 2,1%), com teste da antiglobulina direta negativo. Função renal era preservada. Havia discreta elevação em transaminases, mas com fosfatase alcalina de 2213 U/L. A partir das alterações observadas foi possível definir um quadro de microangiopatia trombótica (MAT) e, diante da possibilidade de púrpura trombocitopênica trombótica (PTT) – PLASMIC score intermediário, foi iniciada plasmaférese. A paciente foi submetida a quatro sessões terapêuticas, que foram suspensas após a suspeita de MAT secundária, a partir dos achados adicionais de um mielograma hipocelular e uma tomografia de tórax, abdome e pelve com lesões líticas em corpos vertebrais. Foi realizada extensa propedêutica na investigação da neoplasia primária, entretanto, a paciente evoluiu com piora no padrão respiratório, elevação progressiva de bilirrubina direta, citopenias refratárias e hematúria macroscópica, com óbito 20 dias após a admissão. Necropsia revelou tratar-se de um adenocarcinoma gástrico difuso, com disseminação em todos os órgãos avaliados, incluindo a presença de células neoplásicas na circulação pulmonar, além de extensa necrose medular. Discussão/Conclusão: A MAT associada ao câncer é um evento muito raro, com incidência estimada de 0,25-0,45/milhão/ano. Sua fisiopatologia envolve a ocorrência de metástases microvasculares, com a indução de anormalidades homeostáticas e um estado pró-trombótico, além da ocorrência de necrose medular metastática. É importante suspeitar da MAT associada ao câncer e diferenciá-la da PTT, não apenas porque possuem tratamentos diferentes, mas também pela possibilidade de diagnóstico da neoplasia de base, permitindo um tratamento direcionado, seja com objetivo curativo ou paliativo.

Introdução/Objetivo: Avaliação do tratamento dos pacientes com diagnóstico de anemia aplásica (AA) grave e muito grave no serviço de hematologia do Hospital das Clínicas da UFMG entre maio de 2021 e dezembro de 2023, submetidos a imunossupressão com imunoglobulina antitimócito de coelho 2,5 g/kg/dia por 5 dias e ciclosporina 5 a 6 mg/kg/dia e eltrombopag 150 mg/dia. Este trabalho possui como objetivo avaliar a resposta ao tratamento com imunossupressão tripla em nosso centro. Métodos: Análise observacional e retrospectiva de pacientes tratados com terapia imunossupressora com AA grave e muito graves. Análise feita por registro de prontuário e resultado de exames. Foram incluídos todos os pacientes com diagnóstico de AA primária adquirida e idade superior a 18 anos e que não tinham doador aparentado HLA compatível ou idade superior a 40 anos independente do doador. Os diagnósticos foram classificados, a partir da hipocelularidade medular menor que 30% em biópsia de medula óssea como: A) AA grave se 2 de 3 critérios: 1) Reticulócito < 60.000; 2) Neutrófilo < 500/mm3 e 3) Plaquetas < 20.000/mm3 e 2) AA muito grave se preenche critérios de AA grave, porém com neutrófilos ao diagnóstico < 200/mm3. Foram excluídos AA de causa hereditária e secundária. A definição de resposta completa (RC): quando o paciente apresenta níveis de hemoglobina > 10 g/dL, neutrófilos > 1.500/mm3 e plaquetas > 100.000/mm3. Resposta parcial (RP): quando ocorre suspensão da necessidade transfusional e o paciente não apresenta mais critérios de doença grave. Resultados: Nesses períodos foram tratados 11 pacientes com AA com imunossupressão, sendo 7 pacientes com 3 drogas, dos quais 4 eram AA muito grave (57%) e 3 eram AA grave (43%). A idade média ao diagnóstico foi de 26,5 anos, 86% do sexo masculino (6/7), 28% possuíam clone HPN (2/7) e o tempo médio entre o diagnóstico e o início do tratamento foi de 2 meses e 5 dias. Aos 3 meses de tratamento, dois pacientes (28%) evoluíram para óbito e dois pacientes (28%) tiveram resposta hematológica parcial e o restante não obteve resposta. Na avaliação de resposta aos 6 meses, 2 tiveram resposta completa (40%), 2 respostas parcial (40%) e 1 paciente (20%) ainda não alcançou o follow up. Até o momento, a taxa de resposta foi de 57% (4/7) e a média de tempo para resposta foi de 3 meses. Os 2 pacientes que evoluíram para óbito mantiveram, desde o diagnóstico, agranulocitose e morreram decorrente de choque séptico com disfunções orgânicas múltiplas que impediram o uso das medicações imunosupressoras de forma contínua. Discussão: A terapia imunossupressora é a opção de tratamento para AA muito grave ou grave, que não são elegíveis ao transplante de células tronco. Em comparação ao estudo RACE de 2022, a população estudada possui a mesma média de idade (26,5 X 23 anos), diferindo na prevalência do sexo masculino (86% x 42%) e do número de portadores de clone HPN (28% x 36%). Apesar do número muito pequeno de pacientes, a mediana de tempo de resposta foi de 3 meses, e do estudo de 3.9 meses. No entanto, a taxa de resposta em 6 meses foi de 57%, inferior ao relatado nesse estudo que foi de 79%. Conclusão: Apesar do tamanho limitado da amostra, conseguimos observar resultados semelhantes aos observados na literatura, mas é importante organizar políticas públicas para que o acesso dos pacientes ao tratamento de AA seja disponibilizado mais precoce.

Introdução: A Doença de Gaucher (DG) é uma doença genética rara, autossômica recessiva, causada por mutações no gene GBA1, que resultam na deficiência da enzima glicocerebrosidade e no acúmulo de glicocerebrosídeos predominantemente no fígado, baço e medula óssea. Objetivos: Avaliar a resposta ao tratamento de pacientes com DG tipo 1 acompanhados no ambulatório de Hematologia Geral do Hospital das Clínicas da UFMG (HC-UFMG), e a prevalência de alterações clínicas no seguimento. Material e métodos: Foram analisados 35 pacientes com DG tipo 1 em acompanhamento no ambulatório de Hematologia Geral do HC-UFMG. As informações sobre os pacientes foram coletadas dos prontuários médicos de forma retrospectiva. Foram avaliados os seguintes parâmetros: anemia, medicamento utilizado, falha a tratamento prévio, presença de hepatomegalia, esplenomegalia, manifestações osteoarticulares, Síndrome Parkinson-like, hipertensão pulmonar, astenia, fadiga, e incidência de neoplasias. Resultados: Dos 35 pacientes, 20 (57%) são do sexo feminino. A mediana de idade foi de 40 anos. O tempo em acompanhamento no serviço oscila de 2 a 26 anos. A anemia teve boa resposta ao tratamento, com média do nível de hemoglobina prévia ao tratamento de 11.71 ± 2.47 mg/dL, significativamente menor que dois anos após tratamento (p = 0.003) e no seguimento atual (p = 0.002). Vinte e um pacientes (60%) usam Imiglucerase, 12 pacientes (34,2%) usam Alfa Taliglucerase e 2 (5,8%) usam Miglustate. Houve 17% de falha ao tratamento prévio com Imiglucerase. Foi visto presença de hepatomegalia em 22 casos (62.8%), esplenomegalia em 24 (68.5%), alterações osteoarticulares em 12 (34.2%), Síndrome Parkinson-Like em 2 (5.7%), hipertensão pulmonar em 3 (8.5%), neoplasia em 4 (11.4%), astenia em 16 (45.7%) e fadiga em 17 casos (48.5%). Discussão dos resultados: A variante tipo 1 é a mais frequente na DG, representando cerca de 99% dos casos. O espectro clínico varia desde ausência de sintomas até comprometimento orgânico grave. Anormalidades hematológicas, visceromegalias, distúrbios esqueléticos e síndrome Parkinson-like são parte das manifestações clínicas. O diagnóstico correto e o tratamento precoce com a terapia de reposição enzimática (TRE) (Imiglucerase/Alfa Taliglucerase) ou com inibidor da síntese do substrato (ISS) (Miglustate) reduz as chances de complicações irreversíveis. Com tratamento adequado, a maioria dos doentes se recupera da anemia, assim como observado na amostra analisada. As visceromegalias são comuns ao diagnóstico e podem regredir com o tratamento, entretanto, seu comportamento não é completamente conhecido e sua avaliação quase sempre fica prejudicada pela indisponibilidade de métodos que permitam uma avaliação quantitativa da resposta ao tratamento ao longo do tempo. A hipertensão pulmonar é rara e a resposta à TRE é variável. A Síndrome Parkinson-Like é infrequente e foi observada em 5,7% dos casos deste estudo. A astenia e a fadiga são achados frequentes, e tem grande impacto na qualidade de vida. O risco de neoplasias oscila entre os estudos, mas o risco relativo de desenvolver mieloma múltiplo parece ser maior entre os portadores de Doença de Gaucher. Na amostra estudada, não foi observado nenhum caso de mieloma múltiplo. Conclusão: O tratamento correto é eficaz na melhora dos parâmetros clínico-laboratoriais. Novos estudos, com maior número de pacientes e de longa duração são necessários para avaliação da resposta terapêutica a longo prazo.

Introdução: Parvovírus B19 é um vírus de DNA fita simples que tem como alvo principal células de alto índice mitótico, principalmente os progenitores eritroides da medula óssea. Sua transmissão ocorre por meio de contato próximo entre pessoas, por fômites, secreção respiratória e/ou saliva. As apresentações clínicas associadas à infecção pelo parvovírus B19 variam amplamente, de benignas a fatais, e dependem da idade e do estado hematológico e imunológico do indivíduo afetado. As cinco síndromes clássicas associadas à infecção pelo parvovírus B19 são eritema infeccioso, artropatia, infecção fetal, crise aplástica e, em imunocomprometidos, aplasia pura de série vermelha. Relato de caso: Paciente do sexo masculino, 27 anos, diagnosticado em outubro de 2023 com leucemia mieloide aguda de risco citogenético favorável (CBF-MYH11,FLT3-ITD detectado). Recebeu tratamento de indução com esquema composto por citarabina e daunorrubicina (“7+3”) e obteve remissão completa. À admissão para primeiro ciclo de consolidação, exames laboratoriais evidenciaram anemia grave microcítica e hipocrômica (hb 6,1 g/dL,VCM 78), hipoproliferativa (reticulócitos de 0,03%), sem ferropenia e sem sinais de hemólise apesar de Coombs direto. Encontrava-se afebril, sem rash cutâneo. Mielograma demonstrou hipoplasia isolada da série eritrocítica, com índice granulocítico/ eritroidede 96. Não havia aumento de blastos. Biópsia de medula óssea com celularidade normal para idade, com série eritrocítica extremamente hipocelular. Em ambos, observava-se proeritroblastos (e-caderina positiva e glicoforina negativa) gigantes com inclusões nucleares proeminentes e vacuolizações citoplasmáticas, característicos da infecção peloparvovírus B19. Foi realizada investigação sorológica, com IgG eIgM, inicialmente negativos, mas com soroconversão em nova amostra após 5 semanas. Paciente recebeu tratamento de suporte com transfusão de hemácias. Houve lenta recuperação da série eritrocítica, o que postergou o início da fase de consolidação em um mês. Foi submetido a dois ciclos de consolidação e completa, no momento, oito meses em remissão. Discussão: apesar de mais frequentemente associado ao eritema infeccioso em crianças e adolescentes, o parvovírus B19, em hospedeiros imunocomprometidos, incluindo portadores de neoplasias hematológicas em tratamento, está associado a manifestações clínicas distintas, que podem resultar de infecção primária ou de reativação viral. Tais manifestações podem incluir rash cutâneo na fase precoce, citopenias na fase tardia e falência orgânica. O quadro infeccioso pode se confundir com recidiva da doença hematológica ou toxicidade ao tratamento, sendo necessário alto índice de suspeição para o diagnóstico. Conclusão: A infecção por parvovírus B19 pode causar aplasia pura de série vermelha em pacientes imunocomprometidos, como no caso relatado, onde houve, inclusive, atraso no tratamento da LMA. É necessário alta suspeição para seu diagnóstico, tanto suspeita clínica, quanto morfológica. É crucial, também, enfatizar práticas corretas de higiene e controle de infecção a fim de prevenir transmissões virais.

Diseases of the blood and blood-forming organs ,RC633-647.5 - Abstract
Objetivos: Descrever caso de paciente com diagnóstico de Doença de Rosai Dorfman (DRD) com antecedente de Linfoma de Hodgkin (LH) em resposta completa, com objetivo de reforçar esta entidade como diagnóstico diferencial de linfonodomegalia durante o seguimento clínico de pacientes com antecedente de neoplasia linfoproliferativa tratada, enfatizando a importância do estudo anatomopatológico. Materiais e métodos: Trata-se de um relato de caso, composto de dados clínicos vindos da revisão de prontuário somada a revisão da literatura. Resultados: paciente do sexo feminino, 30 anos de idade, com diagnóstico há 08 anos de linfoma de Hodgkin subtipo esclerose nodular, estadio de Ann Harbor IIB. O LH havia sido tratado com 06 ciclos de quimioterapia com esquema ABVD (doxorrubicina, bleomicina, vinblastina e dacarbazina) e radioterapia de campo envolvido de consolidação (21 sessões - 4 Gy) em região cervical e mediastino, apresentando resposta completa evidenciada por PET-CT. Após 07 anos do término do tratamento, apresentou linfonodomegalia inguinal, bilateralmente, o maior medindo aproximadamente 03 centímetros em seu maior eixo. A paciente não relatava sintomas B. Realizada biópsia excisional de linfonodo inguinal, com resultado de anatomopatológico evidenciando linfonodo com arquitetura extensamente alterada às custas de intensa histiocitose, com emperipolese e presença focal de células atípicas. O estudo imunohistoquímico demonstrou CD20 e PAX5 positivos nos folículos linfoides hiperplásicos, CD3 positivo em pequenos linfócitos, LMP1 e CD1a negativos, CD68 e S100 positivos em numerosos histiócitos, CD30 negativo, CD15 positivo em células mononucleadas sugestivas de linhagem histiocitária; negativo nas grandes células de interesse, IGG positivo em numerosos plasmócitos e IGG4 positivo em raros plasmócitos. Assim, concluiu-se tratar de um quadro de histiocitose sinusal maciça (DRD), com ausência de critérios para o diagnóstico de LH. Paciente permaneceu em seguimento clínico no ambulatório, em tratamento expectante, sem evidência de recaída do linfoma, e sem progressão de linfonodomegalias. Discussão: A DRD foi descrita como histiocitose sinusal com linfonodomegalias de grande monta pelos autores de mesmo nome em 1969. Entretanto, sua etiopatogenia continua pouco compreendida. A subclassificação da doença baseia-se na apresentação clínica, dividindo-a em doença cutânea, familiar ou esporádica (que por sua vez classifica-se em doença nodal, extranodal, relacionada à neoplasia ou a doença autoimune). Na literatura, encontram-se casos de DRD coexistentes com as mais diversas neoplasias sólidas e hematológicas. Em associação a LH, poucos casos foram relatados, alguns de diagnóstico concomitante ao aparecimento da doença linfoproliferativa (em ocasiões no mesmo linfonodo analisado para o diagnóstico) e outros vários anos após o término do tratamento do linfoma, similarmente ao aqui relatado. A DRD esporádica é de bom prognóstico e frequentemente auto-limitada, podendo ser indicada observação ativa, conforme optado neste caso, guardando excisão cirúrgica ou tratamentos sistêmicos para casos em que a linfonodomegalia ou lesões extranodais incorrem em sintomas. Conclusão: Embora infrequente, a DRD deve ser lembrada dentre os diagnósticos diferenciais de linfonodomegalia mesmo em pacientes com doença neoplasia atual ou anterior, o que corrobora a importância da avaliação anatomopatológica no seguimento de pacientes com doença linfoproliferativa.

Objetivos: Descrever o caso clínico de paciente que vive com HIV (PVHIV) cuja investigação de linfonodomegalias e bicitopenia, resultou nos diagnósticos de tuberculose ganglionar e leucemia mieloide aguda (LMA). Há o propósito de evidenciar a possibilidade de coexistência de tais patologias, sendo importante sua consideração. Materiais e métodos: Trata-se de um estudo do tipo relato de caso, cujos dados clínicos são provenientes da realização de revisão de prontuário e a discussão através de revisão da literatura. Descrição do caso: Paciente do sexo feminino de 54 anos, com diagnóstico de HIV desde 2005, com carga viral indetectável, e CD4 de 215. Iniciou em março de 2024, febre vespertina diária, tosse seca, perda de 6kg em 1 mês, linfonodomegalias, lesões cutâneas em membros inferiores, além de anemia normocrômica e normocítica, sem sangramentos. Em investigação, através da biópsia de linfonodo, realizado diagnóstico de tuberculose ganglionar, iniciado tratamento com esquema RIPE. Durante internação, identificada bicitopenia (anemia e neutropenia), sendo realizado um estudo medular com diagnóstico de leucemia mieloide aguda de risco desfavorável (presença de cariótipo complexo), e optado por iniciar indução com esquema 3+7 (citarabina e daunorrubicina), concomitante ao tratamento de tuberculose. Evoluiu com piora progressiva, com a presença de disfunção hepática e respiratória, sendo necessário aumento prosseguir com suporte intensivo. A despeito de medidas clínicas otimizadas, a paciente foi a óbito por choque séptico por Magnusiomyces capitatus (Geotrichum capitatum). Discussão: A infecção crônica pelo vírus do HIV, mesmo que com adequado tratamento e controle com as medicações anti-retrovirais (TARV), pode acarretar em aumento de neoplasias não definidoras da síndrome de imunodeficiência adquirida (SIDA); neste contexto, há de se considerar a possibilidade de desenvolvimento de leucemia mieloide aguda. Não há consenso na literatura se o risco é maior que a população em geral, no entanto, com o envelhecimento da PVHIV, principalmente associado a efetividade dos tratamentos, tem-se evidenciado maior número de casos de LMA nessa população. Além disso, é conhecido que o processo inflamatório proporcionado pela doença viral pode contribuir para a regulação e proliferação das células leucêmicas. Ademais, é importante ressaltar que durante o tratamento quimioterápico não há indicação de suspender terapia antirretroviral, sendo importante inclusive para favorecer reconstituição imune. Conclusão: Na população de PVHIV em que há a presença de citopenias e/ou linfonodomegalias, devemos considerar, entre os diagnósticos diferenciais, mesmo em pacientes com infecções oportunistas, a possibilidade de neoplasias não definidoras de SIDA, entre elas a LMA. Apesar dos tratamentos disponíveis para LMA serem viáveis e seguros para essa população, os resultados de sobrevida ainda são insatisfatórios e chamam a atenção sobre a necessidade de aperfeiçoar novos tratamentos.

Objetivo: Relatar caso de aspergilose disseminada em paciente com leucemia linfoide aguda B em tratamento quimioterápico de indução. Relato de caso: Paciente feminino, 37 anos, com diagnóstico de LLA-B comum em quimioterapia de indução (protocolo BRALLA20), evolui no 11°dia de internação, em período de neutropenia, com paresia em mão esquerda. Em 24 horas, evolui com paresia em todo o membro superior esquerdo e surgimento de lesões cutâneas dolorosas com halo necrótico no dorso; na ocasião realizada pesquisa de galactomanana sérica com resultado positivo e cultura das lesões cutâneas compatível com Aspergillus flavus. Realizada ressonância magnética de crânio compatível com aspergilose angioinvasiva, sendo iniciada anfotericina B empírica. Paciente evoluiu com piora progressiva do quadro neurológico, aumento das lesões intraparenquimatosas e hipertensão intracraniana, além de novas lesões cutâneas; neste contexto, necessitou de suporte intensivo sendo transferida à UTI. Foi submetida drenagem de abscesso fúngico em lobo frontal, com cultura positiva para Aspergillus no material. Após 13 dias de terapia antifúngica, fungigrama demonstrou resistência a Anfotericina sendo realizado escalonamento guiado para Voriconazol. No 29° dia de Voriconazol, evoluiu com sepse de foco pulmonar por Acinetobacter baumanii e Klebsiella pneumoniae ESBL+. Evoluiu a óbito por piora progressiva do quadro infeccioso. Discussão: As infecções fúngicas invasivas são uma importante causa de complicação em imunocomprometidos, principalmente em pacientes com neoplasias hematológicas. Dentre elas, a aspergilose invasiva (AI) é uma grande preocupação nos departamentos de hematologia devido à sua alta incidência e mortalidade associada. As espécies causadoras de AI mais comuns são Aspergillus fumigatus seguido por Aspergillus flavus. A AI ocorre principalmente em pacientes com neutropenia prolongada induzida por quimioterapia e/ou pacientes submetidos a transplante de células tronco hematopoiéticas. A neutropenia apresenta-se como o principal fator de risco para esta complicação, sendo a duração da neutropenia diretamente associada ao aumento do risco. Outros fatores de risco incluem linfopenia e infecções virais respiratórias. Casos de aspergilose disseminada, em especial com acometimento cerebral, são raros e apresentam prognóstico ruim, com mortalidade de aproximadamente 54%. Pacientes com leucemia mieloide aguda e leucemia linfoblástica aguda em terapia de indução a base de citarabina e daunorrubicina constituem as principais populações em risco de aspergilose cerebral (AC). Uso de corticoides am altas doses e por tempo prolongado, também apresenta-se como fator de risco para AC. O diagnóstico de aspergilose cerebral baseia-se em cultura e avaliação anátomo-patológica da lesão cerebral, podendo ser utilizados em conjunto métodos de detecção de material genético do fungo ou quantificação de galactomanana. O tratamento de AI baseia-se em uso de imidazólicos (voriconazol, itraconazol) ou Anfotericina B lipossomal, com boas taxas de resposta. Por outro lado, o tratamento de aspergilose cerebral não apresenta dados concretos na literatura, variando de combinação de imidazólicos, Anfotericina B, ou mesmo combinação de ambos. Conclusão: A aspergilose disseminada apresenta-se como uma patologia de difícil manejo e alta mortalidade, devendo ser suspeitada, diagnosticada e tratada com brevidade, visando maior chance de sucesso do tratamento antifúngico.

Objetivo: Relatar caso de paciente com LMC com gravidez durante tratamento com asciminibe. Relato de caso: Paciente do sexo feminino, 33 anos, com diagnóstico de leucemia mieloide crônica desde 2017, tratada em primeira linha com imatinibe 400 mg, segunda linha com dasatinibe 100 mg e em terceira linha com asciminibe 80 mg/dia, desde maio de 2023, acesso via programa de uso compassivo. A troca dos inibidores de tirosina quinase (ITQ) foi motivada por perda de resposta molecular e citogenética nos dois inibidores de tirosina quinase anteriores, sem mutação do BCR::ABL1. Apesar de orientada contracepção hormonal e método de barreira, paciente fazia uso apenas de contraceptivo oral combinado, e em agosto de 2023, foi diagnosticado gestação gemelar no primeiro trimestre, sendo orientada a suspender asciminibe imediatamente. Foi prescrito Interferon peguilado 180 mcg SC a cada 2 semanas. Após 15 dias da modificação do tratamento, houve perda de resposta molecular, porém sem perda de resposta hematológica. Durante a gestação, a paciente foi acompanhada pela equipe de ginecologia e obstetrícia. Na 32ª semana de gestação, a paciente foi internada por quadro de pré-eclâmpsia, mantendo-se internada até o final da 34ª semana de gestação (fevereiro de 2024), quando foi submetida a uma cesariana, com nascimento de RNPT sexo feminino, vivo, Apgar 8/10, e RNPT sexo masculino, vivo, Apgar 8/10. Apresentou hemorragia pós parto revertida com massagem uterina e ocitocina 20UI, transamin, misoprostol via retal. Evoluiu com pico pressórico e cefaleia pós parto, com indicação de sulfatação de 24 a 25/02/2024. Após 5 dias da alta, retornou para unidade de saúde com hipertensão, sendo internada para controle, com alta após 4 dias, sem mais intercorrências. Recebeu no total 9 doses de Interferon peguilado. Após alta da maternidade, foi suspensa a amamentação e reiniciado asciminibe 80 mg ao dia, com recuperação resposta molecular maior em 2 meses de reinício do tratamento. Discussão: Com a revolução do tratamento da LMC após o surgimento dos ITQ, a população tem alcançado sobrevida semelhante à população geral. O tratamento da LMC em gestantes é uma condição rara e muito desafiadora e por ser conhecido o risco teratogênico associado aos ITQ, principalmente no primeiro trimestre, indica-se suspensão de seu uso quando ocorre gestação, devendo manter-se o monitoramento para avaliar persistência ou perda da resposta, para que possa ser feito o tratamento adequado (seja com interferon alfa ou leucocitoaférese). O asciminibe é um ITQ de 3ª geração com um mecanismo de ação diferente dos demais, atuando no sítio do miristoil. São raros os relatos de gravidez após exposição ao asciminibe. Conclusão: Relatamos um caso de gestação gemelar bem-sucedido após exposição ao asciminibe, com rápida recuperação da resposta molecular após a reintrodução da medicação pós parto. Há necessidade de individualizar a terapêutica da LMC durante a gestação, baseando-se nos níveis dos transcritos BCR::ABL1, resposta hematológica, status da LMC e curso da gravidez. Deve-se manter monitorização molecular regular através do PCR quantitativo. Gestantes com resposta molecular estável e duradoura podem interromper de modo mais seguro o tratamento. No presente caso, a gravidez precoce em início de tratamento com asciminibe, em uma paciente resistente a dois ITQ prévios, sem atingir estabilidade da resposta molecular poderia ter colocado em risco a evolução da doença.

Objetivos: Descrever o caso clínico de paciente com diagnóstico de mieloma múltiplo (MM) tratado e com resposta parcial muito boa (VGPR), que apresentou durante o seguimento anemia refratária, sendo diagnosticado com neoplasia mielodisplásica (SMD) com deleção do braço longo do cromossomo 5 (del(5q)). Materiais e métodos: Trata-se de um estudo do tipo relato de caso, cujos dados clínicos são provenientes da realização de revisão de prontuário e a discussão através de revisão da literatura. Resultados: Paciente masculino de 71 anos, com diagnóstico de MM IgA/Kappa ISS 3. Considerado paciente idoso frágil, com múltiplas patologias prévias, foi considerado inelegível para transplante de medula óssea autólogo, sendo tratado com 6 ciclos de VTd (bortezomibe, talidomida e dexametasona) e ácido zoledrônico mensal. Evoluiu com progressão de doença, sendo optado por esquema de 2ª linha com 6 ciclos de VMP (Bortezomibe, Melfalano e Prednisona). Após o término do tratamento, atingiu VGPR. Ao longo do seguimento, apresentou piora da anemia, no mesmo mês de término do tratamento. Em avaliação laboratorial, evidenciou-se reticulocitopenia grave. Novo estudo medular demonstrou ausência de infiltração por neoplasia de plasmócitos, com presença de atipias de séries granulocítica e de megacariócitos. A avaliação de cariótipo evidenciou a presença de alteração cromossômica, 46, XY,del(5)(q13q31). Nesse contexto, paciente teve o diagnóstico de SMD com del(5q), sendo optado por iniciar tratamento com talidomida, além de inserção em programa de transfusão, havendo melhora sintomática significativa. Discussão: A presença SMD no contexto de neoplasias linfoproliferativas pode ocorrer como consequência do dano genômico cumulativo dos tratamentos prévios da neoplasia ou de novo. No caso em questão, o paciente teve o diagnóstico de MM sem evidência, na avaliação inicial, de alterações citogenéticas ou cito morfológicas relacionadas à SMD. O paciente foi tratado do MM com 2 linhas de tratamento, com exposição a alquilante (melfalano) na última. Entretanto, o intervalo entre a exposição e o diagnóstico de SMD não sugere que o melfalano esteja relacionado na fisiopatologia da SMD. Alguns estudos sugerem que 1 a cada 10 pacientes com o diagnóstico de MM apresentam displasia das linhagens hematopoiéticas ao diagnóstico, sendo atribuído a isso menor sobrevida. Além disso, pelo impacto no microambiente tumoral, há uma modificação na mielotoxicidade ao tratamento quimioterápico, havendo a necessidade de redução de dose, com consequente impacto em sua efetividade; há estudos que também sugerem um favorecimento na proliferação do plasmócito monoclonal. O diagnóstico de SMD com del(5q) é uma entidade importante a ser considerada no contexto de anemias refratárias, que impacta diretamente na qualidade de vida do paciente em virtude da alta necessidade de transfusão de hemocomponentes. Uma opção terapêutica a ser considerada é o uso de imunomoduladores (IMiD) (como a lenalidomida, talidomida), com boa resposta e diminuição da demanda transfusional. No caso em questão, o uso de um IMiD torna-se particularmente interessante pela concomitância do MM e da SMD com del(5q). Conclusão: A associação entre o MM e SMD é algo importante a ser considerado, reforçando a importância da sua pesquisa ao diagnóstico e durante o seguimento do paciente. A presença da SMD com del(5q) impacta significativamente o tratamento e deve ser aventada na presença de anemias graves e refratárias.

Introdução: Escleromixedema é uma alteração cutânea mucinosa de etiologia desconhecida, muitas vezes associada à gamopatia monoclonal. Não existe na literatura definição robusta sobre a forma mais eficaz de tratar essa condição. Relatamos um caso de mieloma múltiplo associado à escleromixedema tratado com Bortezomibe, Talidomida e Dexametasona que obteve expressiva melhora das lesões de pele com o esquema de indução. Caso clínico: M.M.C., 43 anos, iniciou em 2022 seguimento com a Dermatologia por alterações cutâneas difusas, descamativas, infiltrativas / fibróticas, acompanhadas de microstomia, lagoftalmo e madarose, diagnosticadas por biópsia de pele como escleromixedema. Estendida propedêutica e em Abril de 2023 foi identificado pico monoclonal de 1,78 g/dL na fração gama em eletroforese de proteínas séricas, sendo encaminhado para Hematologia para investigação. Tratava-se de gamopatia monoclonal IgG/kappa pela imunofixação sérica, com mielograma evidenciando 12% de plasmócitos atípicos com restrição de cadeia kappa pela imunofenotipagem. Em avaliação complementar, detectadas mais de 2 lesões focais > 5 mm identificadas por ressonância magnética, sem anemia, sem alteração de função renal, cálcio sérico normal. Foi então estabelecido diagnóstico de Mieloma Múltiplo associado à escleromixedema. Iniciado tratamento de indução com Bortezomibe, Talidomida e Dexametasona (VTD) e proposto transplante autólogo de medula óssea. Obteve resposta parcial muito boa após 3 ciclos, bem como melhora expressiva das lesões de pele. Optado por suspensão da quimioterapia após 8 ciclos de VTD por toxicidade (diarreia de difícil controle). Atualmente aguardando transplante autólogo, ainda não realizado por questões logísticas. Discussão: O diagnóstico de escleromixedema associado ao mieloma múltiplo é extremamente raro. A forma mais comum descrita na literatura é associada à gamopatia IgG/lambda, diferente deste caso. Habitualmente pode ser encontrada plasmocitose discreta na medula e a chance de progressão para mieloma múltiplo é pequena. Poderia ter havido atraso desse diagnóstico caso não houvesse sido realizada propedêutica medular para investigação da gamopatia. Quanto ao tratamento, foi feita opção pelo esquema VTD, por ser tratamento disponível para pacientes com mieloma múltiplo elegíveis ao transplante no âmbito do SUS. Não existem estudos randomizados capazes de definir a terapia de escolha nesse cenário. O paciente obteve importante melhora das lesões de pele com o esquema e controle satisfatório do mieloma múltiplo. O uso de melfalano em alta dose com resgate de células-tronco hematopoiéticas poderá aprofundar ainda mais essa resposta e prolongar a sobrevida livre de progressão. Conclusão: O diagnóstico de gamopatias monoclonais de significado clínico pode ser desafiador. É rara a associação do escleromixedema com mieloma múltiplo. Neste caso, o diagnóstico da neoplasia hematológica favoreceu a escolha do tratamento e o paciente obteve boa resposta clínica.

Objetivo: Identificar e sumarizar as informações sobre eventos trombóticos ou hemorrágicos no pós-operatório de pacientes com Hemofilia A congênita sem inibidores, tratados com Emicizumabe. Materiais e métodos: Realizou-se uma revisão narrativa da literatura utilizando a base de dados PubMed, seguindo a metodologia PICO e descritores MeSH específicos. Incluíram-se estudos envolvendo pacientes com HA congênita sem inibidores tratados com Emicizumabe e submetidos a procedimentos cirúrgicos, em inglês ou português. Foram excluídos artigos relacionados a outras condições, HA adquirida, HA com inibidores, estudos in vitro ou em animais, estudos de custo-efetividade, opiniões de especialistas, satisfação dos usuários, revisões e diretrizes. Estudos que envolvessem pacientes com e sem inibidores foram considerados desde que fosse possível diferenciar os dados dos indivíduos sem inibidores. Resultados: Foram encontrados 75 artigos, dos quais 9 artigos cumpriam os critérios de seleção, resultando em um total de 212 pacientes, sendo 68 eram indivíduos sem inibidores que realizaram procedimentos cirúrgicos. A faixa etária foi variada, e o tempo médio de uso prévio do Emicizumabe variou de 2 e 88 semanas. Procedimentos de menor porte foram mais predominantes, com prevalência de remoção de cateter portocath (39,4%) e extração dentária (21,0%). Em 59 procedimentos os pacientes necessitaram de medicação pró-coagulatória adicional no período perioperatório. Durante o acompanhamento ocorreram um total de 7 (9,2%) eventos hemorrágicos, nenhum evento trombótico e 69 (90,7%) procedimentos sem intercorrências. Discussão: Emicizumabe demostrou ser uma medicação segura e eficaz na prevenção eventos hemorrágicos. Os achados demonstram que não houve eventos hemorrágicos significativos no perioperatório e que a medicação não foi um fator predisponente a eventos trombóticos, sendo importante a associação do Emicizumabe à outra medicação pró-coagulatória, o que sugere que isoladamente o Emicizumabe ainda é insuficiente para prevenir desfechos hemorrágicos. A escassez de dados sobre o manejo perioperatório com Emicizumabe e a falta de critérios estabelecidos para a combinação medicamentosa apontam para a necessidade de mais estudos para guiar a prática clínica. Conclusão: O Emicizumabe é uma opção promissora para prevenir complicações em pacientes com HA sem inibidores, mas a prevenção isolada ainda é limitada, sendo necessária a associação de medicações auxiliares. Estudos adicionais são necessários para definir protocolos de manejo perioperatório e melhor compreender o uso do Emicizumabe e seus impactos clínicos.

Introdução/objetivo: Trombose de Veia Esplâncnica (TVE), que inclui trombose de veia porta, mesentérica, esplênica e síndrome de Budd-Chiari, é um evento incomum. A incidência, embora baixa, é relevante, pois pode ser indicativo de condições sistêmicas. Este estudo analisou prontuários de pacientes atendidos em um centro especializado, com o objetivo de identificar etiologias, categorizar os eventos em agudos ou crônicos e avaliar a indicação de anticoagulação. Métodos: Estudo observacional, retrospectivo, conduzido no HC-UFMG. Foram analisados registros de 1155 pacientes de ambulatório especializado em hemostasia, dos quais 119 apresentavam TVE, com eventos ocorridos entre 1994 e 2024. Realizada revisão de prontuários para coleta de dados. Resultados/discussão: Dos 1155 pacientes analisados, 119 têm diagnóstico de TVE (10%), sendo 38 pacientes com trombose em mais de um leito esplâncnico. Trombose isolada de veia porta em 38%, mesentérica 14% e 01 evento isolado de esplênica, relacionado a pancreatite. 17 pacientes apresentaram Síndrome de Budd-Chiari e 7 desses evoluíram com Hipertensão Portal Clinicamente Significativa (HPCS) após a trombose. Aproximadamente 54% dos pacientes apresentavam HPCS, de etiologia cirrótica etanólica, autoimune ou criptogênica, entretanto, a doença esquistossomótica hepatoesplênica foi a mais prevalente (30 pacientes). Destaca-se também a associação com neoplasias não mieloproliferativas (12%), mas considerando 6 pacientes com carcinoma hepatocelular que também cursavam com HPCS. Doença mieloproliferativa foi identificada em 8% dos pacientes, em sua maioria com JAK2 mutado, 6% dos eventos foram associados a alterações laboratoriais sugestivas de trombofilias, incluindo a síndrome do anticorpo antifosfolípide (1,6%) e com menor incidência,1,6% dos pacientes tiveram o diagnóstico de hemoglobinúria paroxística noturna. Dois pacientes tiveram evento relacionado a pancreatite. Dos pacientes que tinham clara relação com cirurgias prévias (11%), a principal apresentação foi como TVE aguda (78%) e 14% como crônica. No geral, a apresentação mais comum foi a crônica, 55% dos pacientes, mantendo a associação com HPCS em 70% dos pacientes. Já nos eventos agudos, a HPCS também é relevante (40%), porém a maioria dos pacientes não apresentam hepatopatia, os fatores de risco que se destacam nas TVEs agudas são: a abordagem cirúrgica prévia (27%) e as neoplasias (20%). Não foi possível classificar todos os pacientes pelo achado de cronicidade ao diagnóstico. Em relação ao tratamento, o benefício da anticoagulação depende da etiologia, cronicidade e risco de sangramento. Dos pacientes analisados, foram anticoagulados inicialmente 79 (60%), sendo que 24% tinham outros eventos trombóticos sincrônicos ou prévios e 52% eram apresentações agudas. A trombose de porta foi a apresentação mais comum, em consonância com a literatura, assim como a associação com hepatopatias/HPCS como principal fator associado, porém a etiologia esquistossomótica diverge da literatura por tratar-se de estudo conduzido em um estado endêmico para tal. Compartilhamos da dificuldade na classificação de eventos em crônicos e agudos, pelas divergências da definição e registros em prontuário. Conclusão: O estudo corrobora a literatura, mas refletindo a endemicidade local. Casos específicos mostram a necessidade de diagnóstico preciso e da individualização terapêutica, que é desafiadora.

This disease is caused by mutations in the AR gene located on the X chromosome, which encodes the protein that structures the androgen receptor, with the role of receiving androgens. Mutation of the AR gene causes complete or partial loss of androgen receptor function, thereby androgen not being obtained and exerting its effect on target organs, resulting in abnormalities of the male reproductive system due to this organ system, differentiating towards feminization under the influence of estrogen. Disease prevention can be achieved by using pre-implantation genetic diagnosis, which enables couples carrying the mutation to have healthy offspring.Aim: To carry out preimplantation genetic diagnosis of androgen resistance syndrome.Methods: Sanger sequencing was used to detect the mutation in the blood samples of the couple, their son, and 01 embryo that were biopsied on the fifth day based on the findings of next-generation sequencing (NGS) of the affected son. We combined Sanger sequencing and linkage analysis using short tandem repeats (STR) to provide diagnostic results.Results: We performed preimplantation genetic diagnosis for AIS on an embryo from a couple who had previously had an affected son. Consequently, one healthy embryo was diagnosed without the variant NM_000044: c.796del (p.Asp266IlefsTer30).Conclusion: We report on a novel variant (NM_000044: c.796del (p.Asp266IlefsTer30)) in the AR gene discovered in Vietnam. The developed protocol was helpful for the preimplantation genetic diagnosis process to help families with the monogenic disease of AIS but wish to have healthy children.Keywords: androgen insensitivity syndrome, AIS, AR gene, preimplantation genetic diagnosis, short tandem repeats, STR

Abstract Anthropometric characteristics in a subject are a good indication of their body-weight status and diagnosis of overweight and obesity. O and O multifactorial, so today the curiosity arises to investigate new risk factors that predispose to increased body weight, including chronotype. The objective of this study is to evaluate the anthropometric characteristics and caloric intake according to the chronotype in sick Ecuadorian adults. This cross-sectional study consisted of 400 men and women aged between 18 and 63 years, who were hospitalized at the Enrique Garcés General Hospital in the city of Quito. Anthropometric measurements were taken using ISAK techniques. Calorie intake was measured by a 24-hour recall and food frequency, and the Horne and Osttberg questionnaire was applied to measure the chronotype of the subjects. Statistical analyses were performed in R and R studio software. The study subjects were classified into 4 groups depending on their chronotype: moderate morning, extreme morning, intermediate, and moderate evening. It was observed that moderate evening subjects had higher values of body weight, high waist circumference, high triceps skinfold, high percentage of fat mass, visceral fat, and caloric intake than the other groups (p < 0.05). Evening chronotype appears to be related to overweight and obesity and caloric intake.

Introduction: Sepsis is a life-threatening infection that results in organ dysfunction due to an increased pathogen load, necessitating urgent intervention. There is a gap in clinicians’ ability to identify septic patients at high-risk with poor outcomes, highlighting the need for validated predictive scores for early intervention, favourable outcomes, and prompt recovery. Aim: To validate the predictive capacity of the Sequential Organ Failure Assessment (qSOFA), Mortality in Emergency Department Sepsis (MEDS), and Acute Physiology and Chronic Health Evaluation (APACHE 2) scores in patients with 28-day mortality and in Intensive Care Unit (ICU) patients due to sepsis. Materials and Methods: This cross-sectional study was conducted on 150 septic patients at the Department of Emergency Medicine, Sri Ramachandra Institute of Higher Education and Research in Chennai, India, between June and December 2022. Parameters assessed included Respiratory Rate (RR), Systolic Blood Pressure (SBP), Mean Arterial Pressure (MAP), temperature, White Blood Cell (WBC) count, platelet count, bilirubin, and creatinine. Descriptive analysis of age, gender, source, RR, GCS, SBP, qSOFA, MEDS, APACHE 2 in 28-day mortality, and ICU patients. Positive correlation and good predictivity of predictive scores (qSOFA, MEDS, APACHE 2) were analysed using Spearman’s Rank Correlation Coefficient (SRCCRs) statistical test in 28-day mortality and ICU patients. Results: A total of 150 septic patients (male: female-93:57) with an average age of 57.07±14.4 years were included. Urosepsis was the most common (n=51), followed by respiratory sepsis (n=48). Of these, 96 patients were admitted to the ICU, and 54 patients experienced 28-day mortality. The average and median values of RR were 27.1±7.64 breaths/minute (b/m) and 26 b/m, respectively. SBP values were 106.13±30.47 mmHg and 110 mmHg, respectively. Diastolic Blood Pressure (DBP) values were 66±16.51 mmHg and 60 mmHg, respectively. The average and median values of GCS were 12.75±3.92 and 15, respectively. The average for qSOFA was 29.1±0.025, with a median of 28; for MEDS, the average was 7.99±5.89, with a median of 7; and for APACHE 2, the average was 16.74±9.64, with a median of 15. Spearman’s Rank Correlation Coefficient (SRCCRs) demonstrated a strong positive correlation and good predictive validity between qSOFA, MEDS, and APACHE 2 scores in 28-day mortality and ICU patients (

Abstract Background The prognostic and theragnostic role of histopathological subsets in systemic sclerosis interstitial lung disease (SSc-ILD) have been largely neglected due to the paucity of treatment options and the risks associated with surgical lung biopsy. The novel drugs for the treatment of ILDs and the availability of transbronchial cryobiopsy provide a new clinical scenario making lung biopsy more feasible and a pivotal guide for treatment. The aim of our study was to investigate the usefulness of lung biopsy in SSc ILD with a systematic literature review (SLR). Methods PubMed, Embase and Cochrane databases were searched up to June 30, 2023. Search terms included both database-specific controlled vocabulary terms and free-text terms relating to lung biopsy and SSc-ILD diagnostic and prognosis. The SLR was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA). Studies were selected according to the PEO (population, exposure, and outcomes) framework and Quality assessment of diagnostic accuracy studies (QUADAS) were reported. Results We selected 14 articles (comprising 364 SSc-ILD patients). The paucity and heterogeneity of the studies prevented a systematic analysis. Diffuse cutaneous SSc was present in 30–100% of cases. Female predominance was observed in all studies (ranging from 64 to 100%). Mean age ranged from 42 to 64 years. Mean FVC was 73.98 (+/-17.3), mean DLCO was 59.49 (+/-16.1). Anti-Scl70 antibodies positivity was detected in 33% of cases (range: 0-69.6). All patients underwent surgical lung biopsies, and multiple lobes were biopsied in a minority of studies (4/14). Poor HRCT-pathologic correlation was reported with HRCT-NSIP showing histopathologic UIP in up to 1/3 of cases. Limited data suggest that SSc-UIP patients may have a worse prognosis and response to immunosuppressive treatment compared to other histopathologic patterns. Conclusions The data from this SLR clearly show the paucity and heterogeneity of the studies reporting lung biopsy in SSc ILD. Moreover, they highlight the need for further research to address whether the lung biopsy can be helpful to refine prognostic prediction and guide therapeutic choices.

Logistic regression analysis was performed to assess the factors associated with frailty. Frailty was adjusted for demographic and geriatric variables and comorbidities to assess its impact on hospitalization.Results: Overall, 420 patients (median age 70 years [interquartile range, 65– 77]; men, 74.5%) who completed the 3-month follow-up period were analyzed. Coronary revascularization for > 1 year was the most common clinical scenario for CCS (59.8%; n = 251). The prevalence of non-frail, pre-frail, and frail patients were 22.4% (n = 94), 49.7% (n = 209), and 27.9% (n = 117), respectively. In the adjusted model, three factors associated with frailty were age ≥ 75 years (odds ratio [OR] 2.29, 95% confidence interval [CI] 1.39– 3.75, P = 0.001), limitations in instrumental activity of daily living (OR 3.89, 95% CI 2.33– 6.48, P < 0.001), and heart failure (OR 2.30, 95% CI 1.32– 4.02, P = 0.003). The overall 3-month hospitalization rate was higher in frail patients than in non-frail patients (23.9% vs 13.5%, P = 0.012). Frailty was associated with hospitalization (OR 1.85, 95% CI 1.04– 3.30, P = 0.037) but in a weak strength of association (r = 0.126).Conclusion: The prevalence of frailty was 27.9% in the elderly patients with CCS. Age ≥ 75 years, limitations in functional status, and heart failure were associated with increased odds of frailty. Frailty was a predictor of 3-month all-cause hospitalization in these patients.Keywords: frailty, chronic coronary syndrome, elderly

This study was conducted to comprehensively investigate the clinical features, brain imaging findings, and treatment outcomes of patients diagnosed with cerebral venous thrombosis.Materials and Methods: Conducted as a cross-sectional descriptive study, patients diagnosed with cerebral venous thrombosis were enrolled at Can Tho Central General Hospital between January 2021 and June 2022.Results: Notably, a substantial proportion of patients (83.4%) exhibited signs of brain damage, with intracranial hemorrhage (50%), brain infarction (30.9%), subarachnoid hemorrhage (16.6%), and hemorrhagic infarct (4.7%) being the predominant findings. Thrombosis primarily affected the superior sagittal sinus (85.7%), transverse sinus (52.4%), and sigmoid sinus (42.8%). All patients received anticoagulation treatment, resulting in a favorable recovery upon hospital discharge for the majority (90.5%), while a small percentage (9.5%) experienced critical illness or death.Conclusion: Our study on cerebral venous thrombosis found diverse clinical presentations, primarily headache. Intracranial hemorrhage was common, affecting superior sagittal, transverse, and sigmoid sinuses. Most patients achieved favorable recoveries with anticoagulation treatment, emphasizing early intervention’s importance.The plain language summary: Cerebral venous thrombosis (CVT) is a less common condition when compared to arterial thrombosis, which has received more research attention. However, CVT has not received the same level of focus and investigation. The study aimed to comprehensively examine the clinical features, brain imaging findings, and treatment outcomes of patients diagnosed with CVT. The findings revealed that patients with CVT commonly presented with symptoms such as headache, limb weakness, seizures, vomiting, and consciousness disorders. Neuroimaging showed significant brain damage, including intracranial hemorrhage and brain infarction. However, with appropriate anticoagulation treatment, the majority of patients achieved favorable recoveries. The study emphasizes the importance of early intervention and highlights the need for improved diagnostic accuracy and treatment strategies for CVT.Keywords: cerebral venous thrombosis, CVT, hemorrhagic infarct, superior sagittal sinus

The distribution and antimicrobial resistance (AMR) pattern of S. aureus varies by population, time, geographic location, and hospital wards. In this study, we elucidated the epidemiology and AMR patterns of S. aureus isolated from a general hospital in Vietnam.Methods: This was a cross-sectional study. Data on all S. aureus infections from 2014 to 2021 were collected from the Microbiology department of Military Hospital 103, Vietnam. Only the first isolation from each kind of specimen from a particular patient was analyzed using the Cochran–Armitage and chi-square tests.Results: A total of 1130 individuals were diagnosed as S. aureus infection. Among them, 1087 strains were tested for AMR features. Most patients with S. aureus infection were in the age group of 41– 65 years (39.82%). S. aureus isolates were predominant in the surgery wards, and pus specimens were the most common source of isolates (50.62%). S. aureus was most resistant to azithromycin (82.28%), erythromycin (82.82%), and clindamycin (82.32%) and least resistant to teicoplanin (0.0%), tigecycline (0.16%), quinupristin-dalfopristin (0.43%), linezolid (0.62%), and vancomycin (2.92%). Methicillin-resistant S. aureus (MRSA) and multidrug-resistant (MDR) S. aureus were prevalent, accounting for 73.02% and 60.90% of the total strains respectively, and the strains isolated from the intensive care unit (ICU) had the highest percentage of multidrug resistance (77.78%) among the wards.Conclusion: These findings highlight the urgent need for continuous AMR surveillance and updated treatment guidelines, particularly considering high resistance in MRSA, MDR strains, and ICU isolates. Future research focusing on specific resistant populations and potential intervention strategies is crucial to combat this rising threat.Keywords: Staphylococcus aureus, antimicrobial resistance, methicillin-resistant S. aureus, multidrug resistance, Hanoi, Vietnam

Fasting blood glucose (FBG), HbA1c, and serum fructosamine were measured simultaneously. GG was calculated as the difference between the measured and fructosamine-based predicted HbA1c levels (FHbA1c).Results: There was a moderately positive correlation between HbA1c and fructosamine concentration (r = 0.488; p < 0.001). GG was positively correlated with UACR (r = 0.3275; p = 0.0007), negatively correlated with eGFR (r = − 0.3400; p = 0.0004). HbA1c was positively correlated with UACR (r = 0.2437; p = 0.0127) but not correlated with eGFR (r = − 0.444; p = 0.6542). Fructosamine has a positive correlation with eGFR (r = 0.2426; p = 0.0131) but not with UACR (r = − 0.1021; p = 0.3025).Conclusion: GG was positively correlated with UACR and inversely correlated with eGFR in type 2 Diabetes mellitus patients. This suggests that GG is a valuable index for predicting kidney complications due to diabetes.Keywords: type 2 diabetes, HbA1c, fructosamine, glycated gap, glomerular filtration rate, urinary albumin-creatinine ratio

This study aimed to assess the safety and efficacy of VISPOTM, a standardized saw palmetto oil (2– 3% β-sitosterol), in subjects with mild-to-moderate AGA.Methods: In a double-blind, placebo-controlled, four-arm clinical study, 80 healthy male and female subjects aged 18– 50 years were randomly allocated (1:1:1:1) to receive either 400 mg capsules of VISPO or 5 mL of a topical formulation containing 20% VISPO or the respective placebo once daily for 16 weeks. The primary endpoints included hair count (hair comb and hair pull tests) and the self-assessment of perceived efficacy. Objective evaluation was performed using the global photographic assessment score. Hair density, thickness, and anagen/telogen ratio were evaluated using phototrichogram analysis.Results: At the end of the study, oral and topical formulations of VISPO reduced hair fall by up to 29% (p< 0.001) and 22.19% (p< 0.01) from the baseline, respectively. Hair density increased by 5.17% and 7.61% in the oral and topical VISPO groups, respectively (p< 0.001). In addition, oral ingestion of VISPO resulted in a marked reduction in serum dihydrotestosterone (DHT) levels in the subjects compared to placebo (p< 0.001). However, the effect of the VISPO formulations on the anagen/telogen ratio was insignificant. No serious adverse effects were observed during the study.Conclusion: VISPO formulations reduced hair fall and promoted hair regrowth and scalp appearance in AGA patients.Keywords: hair loss, androgenetic alopecia, saw palmetto, β-sitosterol, fatty acids

Intralesional injection therapy, such as the use of triamcinolone, has emerged as an effective treatment option for hypertrophic scars. The objective of this study was to describe the morphological features of hypertrophic scars, categorize them, and evaluate the efficacy of triamcinolone injection therapy in treating these scars.Materials and Methods: A cross-sectional descriptive study of 80 patients with hypertrophic scars treated with triamcinolone intralesional injection at Can Tho University of Medicine and Pharmacy Hospital from 5/2018 to 5/2021.Results: There were 80 patients in all, with a male/female ratio of 1/1.05 and a median age of 15– 35. There were 129 scars in all, with scar age > 1 year accounting for 83%, keloid scars accounting for 64%, and hypertrophic scars accounting for the remaining 36%. Scars are most commonly seen on the trunk, accounting for 53.5% of all scars, particularly on the anterior chest wall. When the source of scars was discovered, trauma and acne accounted for 24% and 23%, respectively, while the rest were predominantly spontaneous scars, accounting for 49%. Scarring and discomfort of mild to moderate severity were common clinical symptoms; scars larger than 5cm in size had more symptoms than scars smaller than 5cm. Prior to the therapy, the mean Vancouver Score Scale-VSS was 6.55± 2.13. After 24 weeks of the therapy, 96.7% of patients had entirely improved itching symptoms, 75% had completely improved pain, and 25% still had minimal pain. After therapy, the mean Vancouver Score Scale-VSS was 2.55± 1.81 (p< 0.05). At week 24, 3.75% of patients experienced skin shrinkage, 3.75% experienced depigmentation, and 13.75% experienced vasodilation.Conclusion: Triamcinolone intralesional injection should be utilized as a first-line therapy for hypertrophic scarring.Plain Language Summary: This study looked at the effectiveness of triamcinolone injection (TAC) therapy in treating hypertrophic scars, which can cause significant cosmetic and psychological problems for patients. The study included 80 patients who had hypertrophic scars and were treated with triamcinolone injections over a period of 24 weeks. The majority of the scars were keloid scars (64%) and had an age of over one year (83%). Scars were most commonly found on the trunk, especially the anterior chest wall. The most common sources of scarring were trauma and acne. Mild to moderate scarring and discomfort were common symptoms, with larger scars having more symptoms. Before treatment, the mean Vancouver Score Scale-VSS was 6.55± 2.13. After 24 weeks of treatment, 96.7% of patients had improved itching symptoms, 75% had improved pain, and 25% still had minimal pain. The mean Vancouver Score Scale-VSS was also significantly reduced after treatment (2.55± 1.81). Some side effects were observed, such as skin shrinkage, depigmentation, and vasodilation, but these were experienced by a small percentage of patients. Based on these results, the study concludes that triamcinolone injection therapy should be considered as the first-line treatment for hypertrophic scarring. This therapy was found to be effective in reducing symptoms and the overall appearance of scars, with few side effects. This study provides valuable information for healthcare professionals who treat patients with hypertrophic scars, and may help improve the quality of life for those affected by this condition.Keywords: clinical features, hypertrophic scar, triamcinolone intralesional injection

The magnetic properties of IO-NPs enable a variety of biomedical applications. We evaluated the usage of IO-NPs for anticancer effects. This paper lists the applications of IO-NPs in general and the clinical targeting of IO-NPs. The application of IONPs along with photothermal therapy (PTT), photodynamic therapy (PDT), and magnetic hyperthermia therapy (MHT) is highlighted in this review’s explanation for cancer treatment strategies. The review’s study shows that IO-NPs play a beneficial role in biological activity because of their biocompatibility, biodegradability, simplicity of production, and hybrid NPs forms with IO-NPs. In this review, we have briefly discussed cancer therapy and hyperthermia and NPs used in PTT, PDT, and MHT. IO-NPs have a particular effect on cancer therapy when combined with PTT, PDT, and MHT were the key topics of the review and were covered in depth. The IO-NPs formulations may be uniquely specialized in cancer treatments with PTT, PDT, and MHT, according to this review investigation.Keywords: cancer, hyperthermia, iron oxide, magnetic hyperthermia, photodynamic therapy, photothermal therapy, near-infrared

Collagens are designed to form supporting aggregates in the extracellular spaces of our body, but they can be isolated from animal sources and processed to become available as biomaterials with wide applications in biomedicine and bioengineering. Collagens can be conveniently modified chemically, and their propensity for participating in crosslinking reactions is an important feature. While the crosslinking promoted by a variety of agents provides a range of collagen-based products, there has been minor interest for therapies based on the crosslinking of collagen while located within living connective tissues, known as exogenous crosslinking. Currently, there is only one such treatment in ocular therapeutics (for keratoconus), and another two in development, all based on mechanical augmentation of tissues due to ultraviolet (UV)-induced crosslinking. As seen in this review, there was some interest to employ exogenous crosslinking in order to reinforce mechanically the lax tendons with an aim to arrest tear propagation, stabilize the tissue, and facilitate the healing. Here we reviewed in details both the early stages and the actual status of the experimental research dedicated to the topic. Many results have not been encouraging, however there is sufficient evidence that tendons can be mechanically reinforced by chemical or photochemical exogenous crosslinking. We also compare the exogenous crosslinking using chemical agents, which was predominant in the literature reviewed, to that promoted by UV radiation, which was rather neglected but might have some advantages.Keywords: collagen, crosslinking, tendon, chemical agents, ultraviolet radiation, mechanical properties

A multivariate analysis of variance test, Pearson Correlation, and analyzing mediating variable interaction is used to analyze data.Results: The findings suggested a significant interaction between personality traits, specifically extraversion and neuroticism, and physical aggression, verbal aggression, and anger. Students with higher levels of personality had higher levels of verbal aggression, and students with higher levels of physical aggression and anger had stronger personality traits than others and lower levels of physical aggression and anger. Personality traits, specifically extraversion, and neuroticism, differed significantly by gender and school years in adolescence. Mediation analysis revealed a positive and statistically significant indirect correlation between personality traits and physically aggressive behavior, with anger as a mediator. Similarly, a positive and statistically significant indirect correlation between personality traits and verbally aggressive behavior through anger was found. The relationship between personality traits and physical aggression was also significant via verbal aggression and anger.Conclusion: This study improved our understanding of personality traits and verbal or physical aggression. Most crucially, physical and verbal aggression mediate personality traits and aggressive conduct. In secondary school, gender and school year affected extraversion and neuroticism. This discovery illuminates personality-based aggressiveness intervention.Keywords: adolescent, personality, aggressive behavior, physical aggression, verbal aggression

No TACE or LVD procedure-associated complications occurred, except for 1 case presenting with grade A liver failure after LVD (then recovered after 7 days). The FLR volume was 29.3% (interquartile range [IQR] = 7.5) and 48.9% (IQR = 8.6) of the total liver volume before and after LVD, respectively (p < 0.001). The degree of hypertrophy and FLR hypertrophy rate were 14.8% (IQR = 8.4) and 55.2% (IQR = 36.7), respectively. All 27 patients demonstrated sufficient FLR after LVD (24 patients at three weeks post-LVD, one at six weeks, and two at ten weeks), but only 21 patients accepted surgery. Postoperative histopathology showed 16 patients with cirrhosis and five with mild fibrosis (F1, F2). One patient presented with severe intraoperative bleeding due to damage of left hepatic vein and developed grade C liver failure, then died on day 32 postoperation.Conclusion: LVD following TACE seems to be a safe, effective, and feasible method of inducing significant FLR regeneration in HCC, even in well-selected cirrhotic livers. Comparative studies with a large patient population and multicenter data are needed for further evaluation.Keywords: hepatic vein embolization, hepatocellular carcinoma, liver hypertrophy, liver resection, liver venous deprivation, portal vein embolization

However, caregivers’ satisfaction with immunization systems affects their decisions on immunization for their children. This study evaluated the levels of clients’ satisfaction toward child immunization and to identify its associated factors.Methods: A cross-sectional study was conducted at 40 commune health centers (CHCs) in 24 districts in Ho Chi Minh City, Vietnam among 1200 caregivers of children aged under 5 years. Clients who took their children to CHCs for immunization were recruited based on convenience sampling technique and were asked to complete a self-report questionnaire. Satisfaction was measured using the Satisfaction with Immunization Service Questionnaire (SWISQ). Ordinal logistic regression models were fitted to identify factors associated with satisfaction levels.Results: The majority of participants were female (85.5%) with a mean age of 33.3 (standard deviation = 9.0). Approximately 60% of participants reported a moderate (40.2%) or high (17.1%) level of satisfaction. Participants with older children and those who waited for a longer duration had a lower satisfaction level. In contrast, high satisfaction level was found to be positive associated with being reminded by healthcare workers and the condition of follow-up areas, vaccine storage and the immunization process met participant’s need.Conclusion: The level of clients’ satisfaction toward child immunization at grassroot healthcare centers in Ho Chi Minh City is relatively low, with 40.2% having moderate satisfaction and 17.1% having high satisfaction. Strategies to improve vaccination programs at CHCs are needed, focusing on clients’ experiences at CHCs during vaccination sessions. Further studies are also needed to have an in-depth understanding of more factors affecting satisfaction in this population.Keywords: service satisfaction, child immunization, community healthcare center, Vietnam

The anxiety about COVID-19 was evaluated by the fear of COVID-19 (FOC) scale. A self-developed questionnaire was used to assess work conditions and HCW’s major concerns and preparedness. Ordinal logistic regression was used to identify factors associated with the severity of PTSD. A structural modeling equation (SEM) model was fitted to examine the correlation between PTSD and other psychological disturbances.Results: A total of 542 HCWs participated in this study. The prevalence of PTSD was 21.2%, most cases were mild. In the ordinal logistic regression analysis, a history of mental illness, poor preparedness, working in a condition with poor resources, a greater number of concerns, and greater fear of COVID-19 were independently associated with higher severity of PTSD. The prevalence of depression, anxiety, and stress was 46.8%, 38.3%, and 60.2, respectively. In the SEM model, PTSD and psychological disturbances had a strong correlation (standardized covariance 0.86).Conclusion: The prevalence of PTSD and other psychological disturbances was alarmingly high among HCWs who worked at COVID-19 field hospitals. The reported associated factors can be useful for policymakers and health authorities in the preparation for future pandemics.Keywords: PTSD, COVID-19, healthcare workers, DASS, fear of COVID, psychological disturbances

Currently, there is no such tool validated for use among pregnant women in Vietnam. This study aims to assess the validity of the Vietnamese version of the 20-item Self Reporting Questionnaire (SRQ-20) by evaluating its reliability, factorial structure, and performance in detecting common mental disorder (CMD) symptoms, thereby identifying the optimum cut-off score for CMD screening among pregnant women in Vietnam.Participants and Methods: A total of 210 pregnant women from four rural communes participated in a face-to-face interview using the Vietnamese version of the SRQ-20, followed by a clinical diagnostic interview based on ICD-10 diagnostic criteria of CMDs. The reliability of the SRQ-20 was assessed by calculating the scale’s Cronbach’s alpha to measure internal consistency. Factor analyses were undertaken to examine the factor structure of the instrument. The Receiver Operating Characteristic (ROC) curve analysis was performed to assess the performance of the SRQ-20 against the clinical diagnosis and to identify the optimum cut-off score.Results: Internal consistency was good, with a Cronbach’s alpha of 0.87. Factor analyses resulted in a 4-factor solution. The area under the ROC curve (AUC) for detection of CMDs was 0.90. The optimum cut-off score of the SRQ-20 for detection of CMD symptoms among Vietnamese pregnant women was 5/6.Conclusion: The Vietnamese version of the SRQ-20 has the capacity to detect CMDs among pregnant women effectively and is recommended for use as a screening tool for CMDs in antenatal care settings in Vietnam.Keywords: SRQ-20, screening, common mental disorders, pregnant women, Vietnam

Medicine - Abstract
Introduction The use of high fraction of inspired oxygen (FiO2) intraoperatively for the prevention of surgical site infection (SSI) remains controversial. Promising results of early randomised controlled trials (RCT) have been replicated with varying success and subsequent meta-analysis are equivocal. Recent advancements in perioperative care, including the increased use of laparoscopic surgery and pneumoperitoneum and shifts in fluid and temperature management, can affect peripheral oxygen delivery and may explain the inconsistency in reproducibility. However, the published data provides insufficient detail on the participant level to test these hypotheses. The purpose of this individual participant data meta-analysis is to assess the described benefits and harms of intraoperative high FiO2compared with regular (0.21–0.40) FiO2 and its potential effect modifiers.Methods and analysis Two reviewers will search medical databases and online trial registries, including MEDLINE, Embase, CENTRAL, CINAHL, ClinicalTrials.gov and WHO regional databases, for randomised and quasi-RCT comparing the effect of intraoperative high FiO2 (0.60–1.00) to regular FiO2 (0.21–0.40) on SSI within 90 days after surgery in adult patients. Secondary outcome will be all-cause mortality within the longest available follow-up. Investigators of the identified trials will be invited to collaborate. Data will be analysed with the one-step approach using the generalised linear mixed model framework and the statistical model appropriate for the type of outcome being analysed (logistic and cox regression, respectively), with a random treatment effect term to account for the clustering of patients within studies. The bias will be assessed using the Cochrane risk-of-bias tool for randomised trials V.2 and the certainty of evidence using Grading of Recommendations, Assessment, Development and Evaluation methodology. Prespecified subgroup analyses include use of mechanical ventilation, nitrous oxide, preoperative antibiotic prophylaxis, temperature (2.5 hour).Ethics and dissemination Ethics approval is not required. Investigators will deidentify individual participant data before it is shared. The results will be submitted to a peer-review journal.PROSPERO registration number CRD42018090261.

Introdução: As síndromes de falências medulares congênitas são menos frequentes do que as adquiridas. Em suas formas clássicas geralmente se manifestam na primeira infância com fenótipo clínico característico e história familiar pertinente. Entretanto, tais entidades podem apresentar espectro amplo e por vezes atípico de manifestações dificultando o reconhecimento precoce. Nos últimos anos os avanços nos métodos diagnósticos resultaram na identificação de etiologias anteriormente não reconhecidas. Nos serviços públicos brasileiros apesar dos testes genéticos não se mostrarem amplamente disponíveis aventar a hipótese de falências congênitas é essencial visto que o diagnóstico precoce implica em tratamento apropriado e antecipação das possíveis complicações. Métodos: Análise retrospectiva dos pacientes atendidos no Ambulatório de Falência Medular do Hospital das Clínicas da Universidade Federal de Minas Gerais, no período de abril de 2022 a abril de 2023. Foram incluídos todos os pacientes com diagnóstico de falência medular congênita e idade superior a 18 anos. Os diagnósticos foram classificados: A) confirmado: pacientes com características hematológicas compatíveis e exames laboratoriais confirmatórios. B) provável: pacientes com características hematológicas compatíveis e alterações fenotípicas e/ou história familiar positiva. C) Possível: pacientes com apenas alterações hematológicas compatíveis. Resultados e discussão: Foram inicialmente analisados 78 pacientes portadores falência medular. Dezenove pacientes (24%) foram incluídos na análise pois possuíam diagnóstico de falência medular congênita. Os demais 59 pacientes (76%) se enquadravam no diagnóstico de aplasia de medula idiopática e foram excluídos. Dentre os 19 pacientes estudados 7 apresentavam diagnóstico confirmado, 8 foram categorizados como diagnóstico provável e 4 pacientes foram classificados como diagnóstico possível. A idade média de diagnóstico das falências medulares congênitas foi de 15,7 anos. Dos pacientes analisados 63 % apresentavam alterações fenotípicas clássicas e 47 % possuíam história familiar de falência medular conhecida. Com relação a gravidade das citopenias apenas 1 paciente preenchia critérios para aplasia de medula grave. Foram registrados 2 casos de neoplasias secundárias, em um paciente portador de Anemia de Fanconi: carcinoma de células escamosas em vulva e carcinoma espinocelular de couro cabeludo. Dados da literatura sugerem que as falências medulares congênitas correspondam a cerca de 10% das falências medulares. A identificação adequada desse grupo de pacientes é fundamental para a condução. Tais indivíduos estão sob risco aumentado de desenvolvimento de neoplasias secundárias necessitando de ações especiais de rastreio e prevenção. Os pacientes com insuficiência medular constitucional são frequentemente encaminhados para transplante de células-tronco hematopoiéticas (TCTH). A identificação de falência medular constitucional antes do TCTH é importante para permitir modificações no condicionamento, bem como a exclusão de doadores familiares portadores do mesmo defeito genético herdado. Conclusão: Distinguir falência medular adquirida de constitucional é desafiador em serviços públicos de países em desenvolvimento, mas importante, dadas as implicações clínicas. Embora heterogêneas na apresentação, síndromes específicas podem ser suspeitadas com base na história pessoal, familiar, nos achados físicos e múltiplos órgãos acometidos.

Introdução: A neoplasia de células dendríticas plasmocitárias blásticas (NCDPB) é uma neoplasia hematológica rara e agressiva, que se manifesta como lesões cutâneas com ou sem envolvimento da medula óssea e disseminação leucêmica. Relato de caso: Paciente de 60 anos, masculino, casado, trabalhador rural, sem comorbidades, iniciou quadro de astenia, perda ponderal, febre, odinofagia e disfagia progressiva com 60 dias de evolução. Associado, exantema difuso em membros superiores, tórax, abdome e dorso, e nódulos cutâneos hipercrômicos, violáceos, endurecidos e indolores em dorso, mamilo e cervical. Amigdalas aumentadas, com áreas de necrose. Exames de imagem demonstravam linfonodomegalias cervicais, toracoabdominais, hepatoesplenomegalia. Hemograma: hb 6,4, plaquetas 10.000, Leucocitose (30.000) com 49% células atípicas. Realizada biópsia de amigdalas, que mostrou células neoplásicas com núcleos pleomórficos, hipercromáticos, cromatina grumosa e nucléolos evidentes e eosinofílicos. Aventada a hipótese de doença linfoproliferativa ou leucose aguda: mielograma mostrava medula óssea hipercelular, 87% de blastos pleomórficos e 6% de monócitos, não visualizados bastonetes de Auer, demais séries hipocelulares. Imunofenotipagem de medula óssea compatível com leucemia aguda com duas populações distintas: 12% de blastos mieloides e 45% de blastos com características de células dentríticas plasmocitoides. Realizada biópsia de lesão de pele, que corroborou com diagnóstico: anatomopatológico demonstrou neoplasia hemolinfopoiética de padrão blástico, imuno-histoquímica com positividade para CD56, CD34, CD43, CD5, CD3, CD117 e HLA-DR, confirmando NCDPB com causa de infiltração da pele. Apresentava cariótipo normal (46, XY) e biologia molecular com BCR-ABL, CBFβ, RUNX1, FLT3 e NPM1 negativos. Paciente apresentava lise tumoral espontânea, iniciadas medidas, além de citorredução com Hidroxiureia. No entanto, evoluiu com choque séptico de foco pulmonar, com disfunção de múltiplos órgãos (renal, hepático e respiratório), evoluindo para óbito 8 dias após a admissão, sem tempo hábil para tratamento específico. Discussão: A NCDPB é uma doença rara, agressiva, que acomete sobretudo adultos, com média de idade de 60 anos, e predominância masculina (2,5:1). As principais manifestações clínicas são lesões cutâneas com ou sem envolvimento da medula óssea e disseminação leucêmica. As lesões cutâneas podem ser castanhas a violáceas, formam placas ou tumores, podendo ser únicas ou disseminadas. Citopenias, linfadenopatia e hepatoesplenomegalia estão presentes na maioria dos casos. Envolvimento das amígdalas, cavidades paranasais, olhos, sistema nervoso central (SNC) têm sido relatados. Nosso paciente apresentava a maioria dessas manifestações, como descrito acima, conduzindo ao diagnóstico, confirmado por exames anatomopatológicos e imunofenotípicos. Apresentava positividade para CD4 e CD56, além de CD123, necessário para o diagnóstico definitivo de NCDPB. Devido à gravidade do quadro clínico e óbito precoce, não iniciado tratamento quimioterápico. Na literatura, indicado uso de Tagraxofusp (anti CD123), não disponível no Brasil. Opta-se por esquemas para leucemia linfoblástica aguda, com consolidação com transplante de medula óssea alogênico. O prognóstico é reservado. Conclusão: A NCDPB é uma doença cujo diagnóstico é desafiador devido a sua raridade, o qual deve ser cogitado em quadros leucêmicos com infiltração de pele, acometimento linfonodal e visceromegalias.

Introdução: As infecções estão entre as principais complicações em pacientes onco-hematológicos. A monitorização da epidemiologia local, dos esquemas antibacterianos utilizados e dos desfechos são indispensáveis para guiar as condutas de tratamento. Objetivos: Avaliar a terapia antibacteriana empírica utilizada na abordagem do primeiro episódio de neutropenia febril e seus desfechos clínicos, assim como o perfil microbiológico das infecções de corrente sanguínea durante as neutropenias febris. MÉTODOS: Estudo observacional, unicêntrico, conduzido no HC UFMG, entre março de 2018 a agosto de 2022. Incluídos pacientes de 18 a 65 anos com diagnóstico de leucemia mieloide aguda (LMA) com intenção de tratamento curativo. Resultados e discussão: Foram incluídos 49 pacientes no estudo, sendo a mediana de idade de 52 anos. Foram observados 142 períodos de neutropenia, sendo 137 episódios de neutropenia febril. Dentre as infecções de corrente sanguínea (ICS) durante os períodos de neutropenia, 69,1% eram bactérias gram-negativas (GN), 22,7% bactérias gram-positivas (GP) e 8,2% fungos. Dentre os GN isolados, os patógenos mais comuns foram Klebsiella sp (42,1%), Escherichia coli (18,4%) e Pseudomonas sp (18,4%). O tempo médio geral para positivação de hemoculturas para GN e GP foi em média 12 horas e 9 minutos e 16 horas e 42 minutos, respectivamente. Os esquemas antibacterianos empíricos iniciais foram guiados conforme o ECIL 2011. 66,4 % dos pacientes foram abordados com terapia de escalonamento: cefepime ou piperacilina tazobactam. 33,5 % dos pacientes receberam terapia de descalonamento dos quais 17,5 % com uso de carbapenêmicos e 16% com esquemas para germes multidroga resistentes. 22,6 % receberam vancomicina empírica no primeiro episódio. Os principais motivos para uso de glicopeptídeo foram infecção cutânea (45%) e choque (35%). Foram registrados 18 casos de choque precoce após o início da febre, dos quais 15 com confirmação de ICS. Dentre os isolamentos microbiológicos 14 correspondiam a GN e 01 GP. Quatro pacientes receberam esquema antimicrobiano com cobertura inadequada ao isolamento microbiológico. Dentre tais pacientes 03 apresentavam ICS por GN e evoluíram para choque precoce. Um paciente possuía ICS por GP e não apresentou intercorrências. Uma morte precoce foi registrada em paciente com ICS por GN. Dos 20 pacientes que faleceram ao longo do período do estudo, 45,0% e 60,0% apresentaram crescimento de GN em pelo menos uma hemocultura nos 7 e 30 dias anteriores ao óbito, respectivamente. Percentual menor quando avaliado o crescimento de GP, presentes em apenas 5,0% e 15,0%, respectivamente. Apesar das limitações do presente estudo, os dados encontrados vão de encontro aos vigentes na literatura sugerindo associação entre ICS por GN com choque precoce e mortalidade. As bactérias GN predominam no nosso serviço, representando 69,1% dos patógenos. A cobertura antibacteriana empírica para GP apesar de encontrada em algumas recomendações vêm sendo desencorajada ao longo dos últimos anos. O atraso inicial da cobertura antibacteriana para GP parece não se relacionar com os piores desfechos precoces. Conclusão: O uso racional da antibioticoterapia empírica e o melhor entendimento do perfil microbiológico das ICS são fundamentais para o melhor manejo dos pacientes onco-hematológicos. A abordagem antibacteriana inadequada das ICS por GN se relacionam a piores desfechos clínicos precoces e tardios.
