- Abstract
In line with our objective of designing new antileishmanial compounds for oral use, we report the synthesis and biological evaluation in vitro of original 4,5-dihydrofuran derivatives bearing an amidoxime group. Previous optimization focused on position 3 of the dihydrofuran ring involving aromatic fragments, resulting in the identification of the compound (HIT) 4-(5-benzyl-3-((4-fluorophenyl)sulfonyl)-5-methyl-4,5-dihydrofuran-2-yl)-N'-hydroxybenzimidamide (IC
50 = 5.4 ± 1.0 μM, L. amazonensis promastigote, IC50 = 7.9 ± 1.1 μM, L. amazonensis intracellular amastigote). In the present work, position 3 was substituted with an aliphatic moiety. This modification was guided by a ligand-based approach, given the unknown biological target or mechanism of action for this compound. The 4,5-dihydrofuran derivatives were synthesized using microwave-assisted manganese (III) acetate-based oxidative cyclization of linear β-keto-carboxylic and β-keto-sulfone substrates, overcoming synthetic challenges to obtain aliphatic derivatives of 4,5-dihydrofuran-3-carboxamides. Finally, an unexpected and interesting biological activity with the 4,5-dihydrofuran-3-carboxylate (IC50 < 5 μM) against the amastigote form is discussed., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests:Oscar Leonardo AVENDANO LEON reports financial support was provided by Colombia Ministry of Science Technology and Innovation.

- Abstract
Introduction: MOGAD encephalitis and ADEM share several clinical features with autoimmune encephalitis (AE) associated with antineuronal antibodies (ANeA); nonetheless, treatment and prognosis differ. Anti-MOG antibodies (abs) are not routinely tested in possible AE, and epidemiological studies on MOGAD encephalitis are scarce., Objectives: To determine the frequency of anti-MOG abs in the serum and CSF in a cohort of possible AE and to compare the clinical characteristics of MOGAD patients and those with seropositive AE., Methods: 481 patients with possible AE from the Brazilian Autoimmune Encephalitis Network underwent tissue-based assay and cell-based assay (CBA) for ANeA. Anti-MOG abs were assessed in serum and CSF with in-house CBA. Clinical and laboratory characteristics of MOGAD and seropositive AE patients were compared., Results: Of the 481 patients, 87 (18 %) had ANeA, and 17 (3.5 %) had anti-MOG abs. Three AE patients with anti-MOG abs and ANeA were excluded from further analysis. Anti-MOG abs were detected in 4 (1.2 %) of the 328 adults and 10 (6.5 %) of the 153 children. Of the 14 patients with MOGAD, nine had ADEM (mostly children), and five had encephalitis (including three adults). Only one patient with ADEM had anti-MOG abs exclusively in CSF. All patients with MOGAD encephalitis were seropositive for anti-MOG abs, and three had normal brain MRI. Patients with MOGAD had fewer behavioral changes (MOGAD 21 % x AE 96 %, p ≤ 0.0001) and movement disorders (MOGAD 42 % x AE 81 %, p = 0.0017) and more demyelinating symptoms, such as myelitis and optic neuritis (MOGAD 14 % x AE 0 %, p = 0.013)., Conclusion: Approximately 3.5 % of patients with possible AE harbor anti-MOG abs, and 0.9 % of the adults had MOGAD encephalitis. Anti-MOG abs were more frequent than other ANeAs regularly tested in AE. We provide evidence that MOGAD is a differential diagnosis in possible AE, even in adult patients with normal brain MRI, and that serum anti-MOG should be considered as an add-on diagnostic tool in AE among adults and pediatric patients., Competing Interests: Declaration of competing interest RH reports the speaker's honoraria from UCB; AD and LECA were employed by Fleury Group; LAD received a grant from Laboratory Fleury without personal compensation; the remaining authors declare no conflict of interest.

- Abstract
Initially, products based on glyphosate (GLY) were considered non-toxic or slightly toxic to bees. Still, recent research has shown that these products can cause mortality or trigger sublethal effects in these insects. Roundup Transorb R® (RT) is one of the GLY-based formulations sold in Brazil. It is used in several crops, and studies are required on its toxicity to honey bees. Thus, the objective of this work was to evaluate, under laboratory conditions, the lethal and sublethal effects of RT for adult workers (foragers) of Africanized A. mellifera. For this, two bioassays were carried out with Africanized honey bees. The experimental design was completely randomized, consisting of five treatments (T0 - control, T25 - 25 % GLY, T50 - 50 % GLY, T75 - 75 % GLY, and T100 GLY - 100 % recommended dose). The bioassays were carried out as follows: (1) Acute oral and topical exposure, evaluating mortality, effects on flight capacity, vertical displacement, and locomotion (in the latter only for oral contamination), consisting of five repetitions and 10 honey bees per repetition; (2) Chronic exposure via the oral route and spraying, assessing mortality, for both contamination routes and damage to the midgut epithelium thickness when contaminated via the oral route, composed of five replicates and 20 honey bees per replicate. The results showed that chronic oral exposure to RT can increase honeybee mortality and damage the thickness of their midgut epithelium. In addition, when acutely exposed orally, the honey bees had reduced walking ability. RT did not affect the other evaluated parameters. Thus, it is concluded that the RT-formulated GLY can affect the survival, midgut morphology, and behavior of A. mellifera., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Michele Potrich reports article publishing charges, equipment, drugs, or supplies, and writing assistance were provided by Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Brazil (CAPES).

- Abstract
The aim of this study was to evaluate whether polymorphisms in SOD2 and SOD3 genes modulate the oral health-related quality of life (OHRQoL) of Para athletes with dental caries experience. The cross-sectional study included 264 Para athletes (143 in athletics, 61 in weightlifting and 60 in swimming). A trained and calibrated team recorded the decayed, missing and filled teeth index (DMFT). The Brazilian version of the Oral Health Impact Profile (OHIP-14) was used to measure OHRQoL. Genomic DNA was extracted from the athletes' saliva, and genetic polymorphisms in the SOD2 (rs5746136 and rs10370) and SOD3 (rs2855262 and rs13306703) genes were analyzed by real-time polymerase chain reaction. Univariate and multivariate analyses were performed. A multivariate General Linear Model analysis, adjusted for sex, revealed that the SOD3 gene polymorphism (rs2855262) had a significant effect on the psychological disability domain [codominant (p = 0.045) and recessive (p=0.038) models]. The SOD2 gene polymorphism (rs5746136) had a significant effect on the total OHIP-14 score [dominant model (p = 0.038)] and the psychological discomfort [dominant model (p = 0.034)] and physical disability [codominant model (p=0.037)] domains. Presence of the SOD2 rs10370 polymorphism led to statistical differences in the total score [codominant (p = 0.026) and dominant (p = 0.023) models] and the handicap domain scores [codominant (p = 0.027) and dominant (p = 0.032) models]. Polymorphisms of the SOD2 and SOD3 genes may be important biomarkers of OHRQoL in Para athletes with dental caries experience.

- Abstract
Primary rectal adenocarcinoma with extensive choriocarcinomatous differentiation is a rare neoplasm, with only sporadic cases reported worldwide. The prognosis is typically poor, and no standard therapy has been established for this tumor. We report a case of a 63-year-old woman who presented with lower abdominal and pelvic discomfort, as well as rectal bleeding. Endoscopy revealed a rectal tumor. She was diagnosed with primary rectal adenocarcinoma with extensive choriocarcinomatous differentiation, accompanied by liver metastasis and peritoneal carcinomatosis. The immunohistochemical profile demonstrated strong and diffuse positivity for keratin (AE1/AE3), beta-human chorionic gonadotropin (β-HCG), p53, MYC, p16, and Ki-67. Molecular analysis indicated mutations in KRAS , TP53 , and PI3KCA . Despite the tumor's profile, the serum β-HCG level was not elevated. A chemotherapy regimen for metastatic colorectal adenocarcinoma was initiated, but there was a poor response, with rapid tumor progression. The patient survived for only 5 months postdiagnosis. We discuss the histopathological, immunohistochemical, and molecular findings, emphasizing their relevance to the differential diagnosis of neoplasms with choriocarcinomatous differentiation., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Objective: To study the effect of antenatal corticosteroid administration on fetal hemodynamics using longitudinal analysis of Doppler waveforms in the umbilical artery (UA) and middle cerebral artery (MCA)., Materials and Methods: This was a retrospective study that included 30 fetuses at risk for preterm birth. Twenty-eight pregnant women were treated with betamethasone for fetal lung maturation. Doppler examinations of the UA and MCA were performed once before and three or eight times after corticosteroid administration. We used a Bayesian hierarchical linear model. Reference ranges were constructed, and associations between variables (gestational age and pre-eclampsia) were tested., Results: The mean maternal age, gestational age at betamethasone administration, and gestational age at delivery were 32.6 ± 5.89 years, 30.2 ± 2.59 weeks, and 32.9 ± 3.42 weeks, respectively. On UA Doppler, there was a significant decrease in the pulsatility index (PI) after corticosteroid administration, with a mean of 0.1147 (credibility interval: 0.03687-0.191) in three observations and a median of 0.1437 (credibility interval: 0.02509-0.2627) in eight observations. However, there was no significant change in the Doppler MCA PI, regardless of gestational age and the presence or absence of pre-eclampsia., Conclusion: Although antenatal corticosteroid administration induced a significant decrease in the Doppler UA PI, we observed no change in the cerebral vasculature.

- Abstract
Objective: To evaluate the maternal-fetal hemodynamic effects after osteopathic manipulative treatment by measuring vital signs and Doppler velocimetry in third-trimester pregnant women., Materials and Methods: This is a prospective study with pregnant women undergoing outpatient follow-up and hospitalized in a ward at Instituto Fernandes Figueira/Fiocruz, between August 2021 to August 2022, during the SARS-CoV-2 pandemic. This study was registered in REBEC under Register Number RBR-9q7kvg and approved by the ethics committee under number 32216620.0.0000.5269. The study population was composed of 51 pregnant women between 28 and 40 weeks of gestation, over 18 years of age, allocated in a single group. Pregnancies with multiple fetuses, malformations, premature rupture of the membrane, and active labor were excluded. The procedures evaluated maternal-fetal hemodynamics using three consecutive measures of ultrasound examination with Doppler velocimetry, and three maternal vital signs measured by an electronic blood pressure monitor., Results: Most vital signs changed after osteopathic treatment. However, only the systolic blood pressure (109.92 ±14.42 to 110.71±12.8, p = 0.033), diastolic blood pressure (79.8±11.54 to 77.57±9.44, p = 0.018) and heart rate (87.59±11.93 to 81.12±10.26, p = 0.000) in the sitting position, systolic blood pressure (110.75±13.26 to 108.59±13.07; p = 0.034) in the supine, and heart rate (83.22±11.29 to 80.39±11.0; p = 0.013) in left lateral decubitus reached statistical significance. The oximetry measures (98.55±0.64 to 98.67±0.68; p = 0.098) stayed stable during all three positions. All artery values remained stable after treatment, and no statistically significant difference was recorded in the artery results., Conclusion: Responses to osteopathic treatment in women in the third trimester of pregnancy did not affect uteroplacental and fetoplacental circulation. However, some maternal vital signs had statistically significant results, with a decrease in diastolic blood pressure and heart rate, and an increase in systolic blood pressure in the sitting position, a decrease of heart rate in the left lateral decubitus position, and systolic blood pressure in the supine position. All the results observed were maintained in the normal parameters. The study responses attest to the safety of using the osteopathic manipulative treatment for the fetus and for pregnant women with comorbidities., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Arruda Correia et al.

- Abstract
Aims: This systematic review aimed to analyze the influence of educational strategies for oral health care for Persons with disabilities (PwDs) on the technical, ethical, and social training of undergraduate dental students., Methods and Results: An extensive search was performed in the following databases: Cochrane, Embase, PubMed, Scopus, Web of Science, LILACS/BBO and OpenGrey database. Observational, nonrandomized, and quantitative comparisons before and after some type of educational strategy in undergraduate dentistry was included. The risk of bias was assessed using the risk of bias in nonrandomized intervention studies (ROBINS-I) tool. The certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. Nine were included and suggested that a significant improvement was observed in the technical training of undergraduate dental students although there was no consensus on the acquisition of ethical/social competences after the application of educational strategies. The included studies presented a moderate to serious risk of bias, and the certainty of evidence for both, technical and ethical/social evaluative constructs, as very low., Conclusion: Although studies show that awareness regarding PwD significantly increases technical skills in dental students, the evidence is poor due to the high risk of bias and inconsistency observed in both the technical and ethical/social constructs; further studies on this topic are therefore essential.

- Abstract
Tissue-engineered skin represents a helpful strategy for the treatment of deep skin injuries. Nevertheless, these skin substitutes must promote and encourage proper vascularization for a successful graft take. Previous work showed that dermal papilla cells (DPC) favour an earlier neovascularization process of grafted skin substitute contributing to the rapid maturation of the neovascular network, reducing inflammation and favouring extracellular matrix remodelling in nude mice. Based on these results, we studied the influence of DPC and its culture conditions on the different stages of angiogenesis in in vitro models. Here, we showed that DPC cultured as spheres favour the expression of angiogenic factors such as VEGF, FGF2 and angiogenin compared to their monolayer culture. To study the effects of DPC on the different stages of angiogenesis, an in vitro model has been adapted. DPC cultured as spheres significantly enhanced HUVEC migration and tubule formation, indicating the importance of employing physiological culture systems that provide a closer representation of cell behaviour and interactions occurring in vivo. Overall, these results allow us to speculate that the use of DPC spheres in skin substitutes could promote its grafting, vascularization and vascular network maturation through the secretion of angiogenic factors. This approach has great potential to improve clinical outcomes in regenerative medicine and skin wound repair., (© 2024 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

- Abstract
Background: The obesity occurrence has achieved epidemic levels worldwide and several studies indicate a paradoxical similarity among obesity and the prognosis in heart failure (HF). The primary objective was to understand the association between body mass index (BMI) and heart failure with reduced ejection fraction (HFREF) of ischemic etiology in outpatients, using mortality as a parameter. The secondary objectives were to determine the differences in HF functional class, pharmacological therapy and evaluate the prognostic value of MAGGIC Score in this population., Methods: We analyzed 1,556 medical records from the HF outpatient clinic of a quaternary hospital and 242 were selected according to the criteria. Most were male, average age 62.6 (56-70), BMI 18.5-24.9 = 35.1%, 25-29.9 = 37.2%, 30-34.9 = 17.8%, 35-39.9 = 7%; BMI <18.5 and >40 groups were eliminated from the central analyzes because of scarce testing., Results: BMI 30-34.9 and BMI 18.5-24.9 had the best prognosis, BMI 25-29.9 had an average performance, and BMI -39.9 group provided the worst outcome ( p = 0.123). In the subcategory analysis, BMI 30-34.9 group had a better prognosis compared to the BMI 35-39.9 group ( p = 0.033). In the multivariate analysis The MAGGIC score was not able to foretell mortality in this population according to BMI., Conclusion: In not hospitalized patients with HFREF of ischemic etiology, obesity was not a protective factor., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Salvino, Sousa, Abrahao, Spineti, Sales, Neves de Albuquerque, Bittencourt, de Moraes, Esporcatte and Mourilhe-Rocha.)

- Abstract
During pregnancy, the various changes women undergo can affect their health status. Manual therapies are important aids because they do not use medication. This study aimed to evaluate the influence of osteopathic manipulative treatment on the intensity of lumbar and pelvic pain and changes in quality of life. This prospective study included women over 18 years old and between 27 and 41 weeks pregnant, and excluded women with fetal malformations, multiple fetuses, premature rupture of membranes, and in labor. Forty-six pregnant women were selected and divided into two groups of ≤3 and ≥4 visits. Statistically significant improvements were observed in the intensity of maximum low back pain (7.54 ± 1.47 vs. 3.815 ± 1.73, p ≤ 0.01) and minimum low back pain (5.67 ± 2.03 vs. 3.111 ± 1.67, p ≤ 0.01), maximum pelvic pain (6.54 ± 2.22 vs. 2.77 ± 1.64, p = 0.01), and minimum pelvic pain (5.615 ± 2.21 vs. 2.615 ± 1.66, p = 0.01). Both groups achieved improvements in quality of life indices, with the improvements achieved by the ≥4-visits group being statistically significant. Osteopathic treatment was effective in reducing the intensity of lumbar and pelvic pain and in improving the quality of life of pregnant women in the third trimester.

- Abstract
Purpose: To evaluate the effects of didactic and clinical training of dental students in treating Persons with Disabilities (PwD) on their self-perceptions about treating PWD., Methods: A pre-and postevaluation of a didactic-clinical educational strategy targeting oral health care of PwD was conducted among fourth-year undergraduate dental students at a Brazilian dental school. Semi-structured questionnaires were used to assess the following work environment parameters: technical, organizational, social, ethical, and managerial acumen. Data were analyzed using Fisher's exact and chi-square tests, with a significance level of 5% (p < 0.05), to verify possible associations between the quantitative variables. A qualitative analysis was conducted through collective subject discourse., Results: Significant differences were found in the self-perception of students' knowledge and abilities in providing low-complexity care for PwD before and after the training program (p = 0.025). Students were more confident about managing and organizing the work environment (p = 0.007) and providing humanized care to PwD (p = 0.042) posttraining program. Additionally, a decrease in the feeling of insecurity (p = 0.014) and feelings of pity, fear, or prejudice toward PwD (p < 0.001) were observed posttraining program., Conclusions: Didactic and clinical training interventions for treating PwD improved the work environment of undergraduate dental students in technical, managerial, organizational, and ethical/social dimensions., (© 2023 American Dental Education Association.)

- Abstract
Objective: To carry out a systematic review to assess the effects of intra-abdominal hypertension on maternal-fetal outcomes., Methods: The search was carried out between 28th June to 4th July 2022 on the Biblioteca Virtual em Saúde, Pubmed, Embase, Web of Science, and Cochrane databases. The study was registered in PROSPERO (CRD42020206526). The systematic review was performed according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: The PRISMA Statement. To assess the methodological quality and control the risk of bias, New Castle was used., Results: A total of 6203 articles were found. Of these, 5 met the selection criteria for a full reading. The selected studies included a total of 271 pregnant women, of which 242 underwent elective cesarean section and measurement of intra-abdominal pressure via a bladder catheter. In both pregnant women groups, the lowest intra-abdominal pressure values were found in the supine position with left lateral tilt. Prepartum values in normotensive women with singleton pregnancy (7.3±1.3 to 14.1 ± 1 mmHg) were lower than in gestational hypertensive disorders (12.0±3.3 to 18.3±2.6 mmHg). In postpartum, the values decreased in both groups but were even lower in normotensive women (3.7±0.8 to 9.9 ± 2.6 mmHg vs 8.5 ± 3.6 to 13.6 ± 3.3 mmHg). The same was true for twin pregnancies. The Sequential Organ Failure Assessment index ranged from 0.6 (0.5) to 0.9 (0.7) in both groups of pregnant women. The placental malondialdehyde levels were statistically (p < 0.05) higher in pregnant women with pre-eclampsia (2.52±1.05) than normotensive (1.42±0.54)., Conclusions: Prepartum intra-abdominal pressure values in normotensive women were close or equal to intra-abdominal hypertension and compatible with gestational hypertensive disorders even in the postpartum period. IAP values were consistently lower in supine position with lateral tilt in both groups. Significant correlations were found between prematurity, low birth weight, pregnant women with hypertensive disorders, and increased intra-abdominal pressure. However, there was no significant association of dysfunction in any system in the relationship between intra-abdominal pressure and Sequential Organ Failure Assessment. Despite the higher malondialdehyde values in pregnant women with pre-eclampsia, the findings were inconclusive. Given the observed data on maternal and fetal outcomes, it would be recommended that intra-abdominal pressure measurements be standardized and used as a diagnostic tool during pregnancy., Trial Registration: PROSPERO registration: October 9th, 2020, CRD42020206526., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Arruda Correia et al.

- Abstract
Background: Vasculitis is an uncommon complication of biologics used to treat inflammatory bowel disease (IBD). This study describes a case series of vasculitis induced by anti-tumor necrosis factor (TNF) therapy in IBD patients., Methods: Retrospective assessments were performed using the medical records of adult IBD patients who underwent outpatient clinical follow-ups between January 2010 and December 2019 in order to identify patients with vasculitis caused by anti-TNF therapy., Results: There were 2442 patients altogether. Of these, 862 (35%) took anti-TNF medication. Five patients (0.6% of the overall patients; n = 3 (60%) Crohn's disease; n = 2 (40%), ulcerative colitis) were identified as having leukocytoclastic vasculitis (LCV) due to anti-TNF therapy; these patients were white, female, and non-smokers. The mean age of LCV diagnosis was 32.2 years, and the mean IBD duration was 7.2 years. The mean time between the start of biologic therapy and LCV onset was 30.8 months. Most of the patients were using adalimumab (80%; n = 4). All the patients were in remission at the time of the LCV diagnosis, and the vasculitis affected the skin in all cases. Anti-TNF therapy was discontinued in the five abovementioned patients, and the response of LCV to the oral steroids was significantly positive. Remarkably, all five patients experienced complete remission from LCV within 4-12 weeks after starting prednisone therapy, and none of them had LCV recurrence in the follow-up period (a mean duration of 28 months)., Conclusions: LCV is an unusual complication of anti-TNF therapy in the IBD setting. In this context, clinicians should have a high degree of suspicion of LCV in patients who develop an unexplained cutaneous rash.

- Abstract
Pallister - Hall syndrome is a rare malformation that involves the presence of a suprasellar hamartoma and associated malformations. Prenatal diagnosis is also rare, and few cases have been reported using magnetic resonance imaging (MRI). A 35-year-old G5P2A2 woman at the 35th week of gestation was referred to our service. Fetal MRI showed an isointense image in the suprasellar region, pushing the brainstem up and backward, and compressing the vermis and cerebellum on T2-weighted images. On T1-weighted images, the hypointense signal of the tumor was similar to that of the brain parenchyma. Ultrasound images showed a suprasellar mass, which was more echogenic than the normal cerebral parenchyma, posteriorly pushing the brain stem, with involvement of the vermis of the tumor and compression of the posterior fossa. Three-dimensional reconstruction using MRI scan data showed a space view of the tumor and its relationships with the other brain tissues allowing better understanding by parents and multidisciplinary team., (© 2023.

Leal da Silva S, Prado FM, Toffoli DJ, and Wetter NU
- Abstract
The photoelastic dispersion coefficient represents the relationship between stress and the differences in refractive indices in a birefringent material. However, determining the coefficient using photoelasticity is challenging, as it is difficult to determine the refractive indices within photoelastic samples that are under tension. Here we present, for the first time, to our knowledge, the use of polarized digital holography to investigate the wavelength dependence of the dispersion coefficient in a photoelastic material. A digital method is proposed to analyze and correlate the differences in mean external stress with differences in mean phase. The results confirm the wavelength dependence of the dispersion coefficient, with an accuracy improvement of 25% compared to other photoelasticity methods.

- Abstract
Objective: To evaluate the positive predictive value (PPV) of amorphous calcifications and to analyze the imaging variables that could alter the risk of malignancy associated with this finding., Materials and Methods: This was a retrospective study of 138 stereotactically guided percutaneous vacuum-assisted biopsies of amorphous calcifications, performed between January 2012 and December 2017. All of the patients included were referred for radiological follow-up for a minimum of one year (if the histopathology showed a benign lesion) or for surgical treatment (if the histopathology showed malignancy or a lesion of uncertain malignant potential)., Results: We found that the PPV of amorphous calcifications was 9.42%. However, most of the malignant amorphous calcifications were in cases of invasive carcinoma or high-grade ductal carcinoma in situ, indicating clinically relevant disease. The relative risk of malignancy associated with amorphous calcifications was 6.15 times higher in patients with a family or personal history of breast or ovarian cancer. Neither being postmenopausal nor having dense breasts was found to be predictive of malignancy in patients with amorphous calcifications., Conclusion: Amorphous calcifications in the breast had a PPV for malignancy of 9.42%, indicating the possibility of placing the finding in subcategory 4a, which requires histopathological analysis. Our finding that the risk of malignancy associated with this subtype of calcifications is up to 6.15 times higher in patients with a family or personal history of breast cancer warrants greater concern regarding the clinical, radiologic, and histopathologic correlations after biopsy.

- Abstract
Background: In 2015, a quality improvement (QI) intervention to reduce cesarean sections (CS)-the Adequate Childbirth Project (PPA)-was implemented in the private sector in Brazil. This analysis aims to compare safety care measures and adverse outcomes between women exposed to the PPA intervention to those receiving standard care., Methods: The analysis included a convenience sample of 12 private hospitals that participated in the PPA (2017-2018). Data collection was performed through chart review and interviews. Differences in 15 outcomes were examined using Pearson's chi-square test and multiple logistic regressions., Results: The final weighted sample was comprised of 4789 births, 2570 in the PPA group (53.5%) and 2227 in the standard care group (46.5%). CS rate was significantly lower in the PPA group (67.3% vs 88.8%). After adjusting for potential confounders, PPA model was associated with decreased overall CS rate (OR = 0.30, 95% CI 0.24 to 0.36), as well as prelabor (OR = 0.41, 0.34 to 0.48) and repeated CS (OR = 0.45, 0.29 to 0.70). In terms of other safety care measures, women in the PPA model had an increased chance of absence of antibiotic prophylaxis in Group B Streptococcus (GBS) + women (OR = 4.63, 1.33 to 16.14) and for CSs (OR = 1.75, 1.38 to 2.22), while those with severe hypertension were less likely to not receiving magnesium sulphate (OR = 0.27, 0.09 to 0.77). Regarding obstetric and neonatal outcomes, PPA model was associated with a decreased chance of having an obstetric anal sphincter injury (OASI) following an episiotomy (OR = 0.34, 0.13 to 0.89), requiring antibiotics other than routine prophylaxis (OR = 0.84, 0.70 to 0.99), having a late preterm (OR = 0.36, 0.27 to 0.48) or early term baby (OR = 0.81, 0.70 to 0.94). There were no statistically significant differences for other outcomes., Conclusions: The PPA intervention was able to reduce CS rates, late preterm and early term deliveries without increasing the chance of adverse outcomes. The bidirectional effect on safety care measures reinforces that QI initiatives includes closer observation of routine care when implementing interventions to reduce C-section rates., (© 2023.

- Abstract
Introduction: The Acute Leukemia-European Society for Blood and Marrow Transplantation (AL-EBMT) risk score was recently developed and validated by Shouval et al. OBJECTIVE: To assess the ability of this score in predicting the 2-year overall survival (OS-2), leukemia-free survival (LFS-2) and transplant-related mortality (TRM) in acute leukemia (AL) adult patients undergoing a first allogeneic hematopoietic stem cell transplant (HSCT) at a transplant center in Brazil., Methods: In this prospective, cohort study, we used the formula published by Shouval et al. to calculate the AL-EBMT score and stratify patients into three risk categories., Results: A total of 79 patients transplanted between 2008 and 2018 were analyzed. The median age was 38 years. Acute myeloid leukemia was the most common diagnosis (68%). Almost a quarter of the cases were at an advanced stage. All hematopoietic stem cell transplantations (HSCTs) were human leukocyte antigen-matched (HLA-matched) and the majority used familial donors (77%). Myeloablative conditioning was used in 92% of the cases. Stratification according to the AL-EBMT score into low-, intermediate- and high-risk groups yielded the following results: 40%, 12% and 47% of the cases, respectively. The high scoring group was associated with a hazard ratio of 2.1 (p = 0.007), 2.1 (p = 0.009) and 2.47 (p = 0.01) for the 2-year OS, LFS and TRM, respectively., Conclusion: This study supports the ability of the AL-EBMT score to reasonably predict the 2-year post-transplant OS, LFS and TRM and to discriminate between risk categories in adult patients with AL, thus confirming its usefulness in clinical decision-making in this setting. Larger, multicenter studies may further help confirm these findings., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2021 Associação Brasileira de Hematologia, Hemoterapia e Terapia Celular.

- Abstract
Objective: To analyze the historical clinical outcomes of children with myelomeningocele (MMC) meeting the criteria for fetal surgery, but who underwent postnatal primary repair., Methods: Data from children undergoing postnatal MMC repair between January 1995 and January 2015 were collected from the Neurosurgery Outpatient Clinic's medical records. Children were included if they had ≥ 1 year of postoperative follow-up and met the criteria for fetal surgery. The children's data were then stratified according to whether they received a shunt or not. The primary outcome was mortality, and secondary outcomes were educational delays, hospitalization, recurrent urinary tract infections (UTIs), and renal failure., Results: Over the 20-year period, 231 children with MMC were followed up. Based on clinical data recorded at the time of birth, 165 (71.4%) qualify of fetal surgery. Of the 165 patients, 136 (82.4%) underwent shunt placement. The mortality rate was 5.1% in the group with shunt and 0% in the group without, relative risk (RR) 3.28 (95% confidence interval, 95% CI, 0.19-55.9). The statistically significant RRs for adverse outcomes in the shunted group were 1.86 (95% CI, 1.01-3.44) for UTI, 30 (95% CI, 1.01-537) for renal failure, and 1.77 (95% CI, 1.09-2.87) for hospitalizations., Conclusion: Children with MMC qualifying for fetal surgery who underwent shunt placement were more likely to have recurrent UTIs, develop renal failure, and be hospitalized. Since approximately half of the shunt procedures could be avoided by fetal surgery, there is a clinical benefit and a possible financial benefit to the implementation of this technology in our setting., Competing Interests: The authors have no conflict of interests to declare., (Federação Brasileira de Ginecologia e Obstetrícia.

- Abstract
Several diseases are characterized by changes in the mechanical properties of erythrocytes. Hemolytic anemias are an example of these diseases. Among the hemolytic anemias, Sickle Cell Disease and Thalassemia are the most common, characterized by alterations in the structure of their hemoglobin. Sickle cell disease has a pathological origin in synthesizing abnormal hemoglobin, HbS. In contrast, thalassemia results in extinction or decreased synthesis of α and β hemoglobin chains. This work presents a detailed study of biophysical and ultrastructural early erythrocytes membrane alterations at the nanoscale using Atomic Force Microscopy (AFM). Cells from individuals with sickle cell anemia and thalassemia mutations were studied. The analysis methodology in the AFM was given by blood smear and exposure of the inner membrane for ghost analysis. A robust statistic was used with 65,536 force curves for each map, ten cells of each type, with three individuals for each sample group. The results showed significant differences in cell rigidity, adhesion, volume, and roughness at early morphological alterations, bringing new perspectives for understanding pathogenesis. The sickle cell trait (HbAS) results stand out. Significant alterations were observed in the membrane properties, bringing new perspectives for the knowledge of this mutation. This work presents ultrastructural and biomechanical signatures of sickle cell anemia and thalassemia genotypes, which may help determine a more accurate biophysical description and clinical prognosis for these diseases.

- Abstract
Coxiella burnetii is a global, highly infectious intracellular bacterium, able to infect a wide range of hosts and to persist for months in the environment. It is the etiological agent of Q fever-a zoonosis of global priority. Currently, there are no national surveillance data on C. burnetii 's seroprevalence for any South American country, reinforcing the necessity of developing novel and inexpensive serological tools to monitor the prevalence of infections among humans and animals-especially cattle, goats, and sheep. In this study, we used immunoinformatics and computational biology tools to predict specific linear B-cell epitopes in three C. burnetii outer membrane proteins: OMP-H (CBU_0612), Com-1 (CBU_1910), and OMP-P1 (CBU_0311). Furthermore, predicted epitopes were tested by ELISA, as synthetic peptides, against samples of patients reactive to C. burnetii in indirect immunofluorescence assay, in order to evaluate their natural immunogenicity. In this way, two linear B-cell epitopes were identified in each studied protein (OMP-H
(51-59) , OMP-H(91-106) , Com-1(57-76) , Com-1(191-206) , OMP-P1(197-209) , and OMP-P1(215-227) ); all of them were confirmed as naturally immunogenic by the presence of specific antibodies in 77% of studied patients against at least one of the identified epitopes. Remarkably, a higher frequency of endocarditis cases was observed among patients who presented an intense humoral response to OMP-H and Com-1 epitopes. These data confirm that immunoinformatics applied to the identification of specific B-cell epitopes can be an effective strategy to improve and accelerate the development of surveillance tools against neglected diseases.- Published

- Abstract
Background: The uncertainties about coronavirus disease 2019 (COVID-19), the change in routine, lifestyles and the reduction of physical contact can cause stress, anxiety, emotional overload, poor sleep and even physical health complications., Aim: To evaluate the scientific publications available on the relationship between COVID-19 and anxiety experienced in the general population, during the period of social isolation, adopted by governmental organizations and public health policymakers as a measure to contain the spread of cases., Methods: A literature search was performed systematically exploring the PubMed and Medline databases using the following terms classified as MeSH descriptors: ("anxiety" AND "pandemic" AND "COVID-19"). For the search, in the Biblioteca Virtual em Saúde - BVS, Science.gov, Web of Science and National Library platforms, the following keywords were used: ("anxiety" AND "coronavirus" AND "social isolation"). Thirty-seven peer-reviewed articles were found. PRISMA and the Downs & Black checklist were used for qualitative evaluation., Results: After applying the inclusion criteria, seven ( n = 7) original scientific articles were selected. The collated evidence demonstrated increased levels of symptoms of anxiety and depression during the period of social isolation. The population between 21 to 40 years was most affected. The risk of severe depression was twice as high at the epicenter of the pandemic. Sleep quality was significantly impaired. Questions about politics, religion, and consumption of products from China were found to generate fear and anticipate probable changes in the pattern of post-pandemic consumption. Social isolation exacerbated feelings of extreme hopelessness, sadness, loneliness and suicidal ideation., Conclusion: We conclude that there is a potential relationship between social isolation during the COVID-19 pandemic and symptoms of anxiety. It is important to note that the direct and indirect costs of not identifying the detrimental effects of this phenomenon and neglecting strategies for intervention could lead to a significant psychological burden on society in several aspects after social isolation., Competing Interests: Conflict-of-interest statement: No conflict of interests., (©The Author(s) 2021.

- Abstract
Background: Venolymphatic malformations are benign. Fetal MRI can more precisely demonstrate an infiltrative pattern of malformations than US., Objective: To evaluate perinatal outcomes and long-term follow-up of fetal venolymphatic malformations treated in different medical facilities using fetal MRI., Materials and Methods: This retrospective cohort study evaluated 20 pregnant women between 22 weeks and 37 weeks of gestation who were referred from different institutions. They presented with fetuses with various diagnoses of cystic masses on routine US. The cases were studied using MRI. We analyzed prenatal data, perinatal outcomes and long-term follow-up., Results: We reviewed the MRI scans of 20 patients with venolymphatic malformation. Referral diagnosis was changed in 40% (8/20) of cases, with postnatal concordance of 100% (20/20). Moreover, 65% (13/20) presented with venolymphatic malformation in more than one body segment. The neck was affected in 70% (14/20) of fetuses, while the head and thorax were affected in 30% (6/20) and 45% (9/20), respectively. There were intrathoracic lesions in 35% (7/20), lesions in the abdomen in 30% (6/20), and lesions in the perineum and extremities in 10% (2/20) each. Tracheal displacement, neck deflection and anatomical displacement caused by tumoral compression were present in 15% (3/20) of cases. Moreover, 25% (5/20) of newborns required neonatal intensive care unit admission, and all presented with cervical or thoracic venolymphatic malformation. Furthermore, 50% (10/20) of cases presented with complete resolution after medical therapy. The intrathoracic and cervical residuals (35%, 7/20) were monitored and treated., Conclusion: MRI showed good correlation with postnatal examination of venolymphatic malformation, was useful in the differential diagnosis of fetal cysts on US, and presented a significant postnatal correlation with thoracic infiltration. The outcomes of prenatally diagnosed venolymphatic malformations are good despite the varying protocols among medical facilities.

- Abstract
Bees are fundamental insects in agroecosystems, mainly due to pollination. However, its decline has been observed in recent years, and the contamination by pesticides is suspected to be responsible. This relationship is the objective of our research, which is the first scientometric study on this subject. The data were obtained from the Web of Science database (1231) and were analyzed using Microsoft Office Excel and CiteSpace. The results point to a significant increase in pesticide and bee reseach in the last 15 years in the most influential scientific journals. The USA and France have the largest number of publications and a moderade relationship between this trait and GDP (gross domestic product) was observed (r = 0.80; r
2 = 0.60). There is no correlation between the use of pesticides and studies of the effects on pollinators and the use of pesticides and the countries' GDP. In general, studies have shown the negative effects of the contamination by pesticides on bees; however, most publications are with bees of the Apis genus, and therefore it is necessary to explore the action of pesticides on bumble bees and wild bees, as well furthur as studies are needed regarding the sublethal effects of these products on bees as the number of molecules used in the management of agricultural crops is vast.- Published

- Abstract
Glyphosate (GLY) is an herbicide widely used in agriculture. First considered as non-toxic or slightly toxic to bees, GLY and its different formulations have shown, more recently, to affect negatively the survival, development and behavior of these insects, even when used in doses and concentrations recommended by the manufacturer. Thus, the results of research on the toxicity of GLY to bees are often conflicting, which makes a meta-analysis interesting for data integration, generating a statistically reliable result. Therefore, this study aimed to evaluate the GLY effects on mortality of bees through a meta-analysis. For this, a search was carried out in the databases Web of Science, CAPES (Coordination for the Improvement of Higher Education Personnel - Brazil), Scopus, and PubMed. Papers that evaluated the effect of GLY on bee mortality published between 1945 and October 2020, were considered. After obtaining the data, R software was used to perform the meta-analytical tests. Sixteen papers on mortality were selected with 34 data sets. Most of the sets demonstrated differences between the control and experimental groups, showing that the treatments with GLY caused higher mortality of bees. The results considering the methodology used (ingestion or contact), the phase of the biological cycle (adults or larvae), and the dose (ecologically relevant dose and recommended by the manufacturer) were different when compared with their respective control groups. Therefore, GLY can be considered toxic to bees. It is important to emphasize that this meta-analysis identified that papers assessing the toxicity of GLY to bees are still scarce, for both lethal and sublethal effects, mainly for stingless and solitary bee species., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier B.V.

- Abstract
Study Objective: To assess individual changes of deep dyspareunia (DDyspareunia) six months after laparoscopic nerve-sparing complete excision of endometriosis, with or without robotic assistance., Methods: This preplanned interdisciplinary observational study with a retrospective analysis of intervention enrolled 126 consecutive women who underwent surgery between January 2018 and September 2019 at a private specialized center. Demographics, medical history and surgery details were recorded systematically. DDyspareunia (primary outcome), dysmenorrhea and acyclic pelvic pain were assessed on self-reported 11-point numeric rating scales both preoperatively and at six-month follow-up. Cases with poor prognosis in relation to dyspareunia were described individually in greater detail., Results: Preoperative DDyspareunia showed weak correlation with dysmenorrhea (rho = .240; P = .014) and pelvic pain (rho = .260; P = .004). Although DDyspareunia improved significantly (P < .001) by 3 points or more in 75.8% (95%CI: 64.7-86.2) and disappeared totally in 59.7% of cases (95%CI:47.8-71.6), individual analysis identified different patterns of response. The probability of a preoperative moderate/severe DDyspareunia worsening more than 2 points was 4.8% (95%CI: 0.0-10.7) and the probability of a woman with no DDyspareunia developing "de novo" moderate or severe DDyspareunia was 7.7% (95%CI: 1.8-15.8) and 5.8% (95%CI: 0.0-13.0), respectively. In a qualitative analysis, several conditions were hypothesized to impact the post-operative DDyspareunia response; these included adenomyosis, mental health disorders, lack of hormone therapy after surgery, colporrhaphy, nodule excision in ENZIAN B compartment (uterosacral ligament/parametrium), the rectovaginal septum or the retrocervical region., Conclusion: Endometriosis surgery provides significant improvement in DDyspareunia. However, patients should be alerted about the possibility of unsatisfactory results., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Bacillus thuringiensis (Bt), an entomopathogenic bacterium, has been used as bioinsecticides for insect pest control worldwide. Consequently, the objective of this work was to evaluate the possible effects of commercial formulations of Bt products, Dipel and Xentari, on the survival and behavior of Africanized honey bees (Apis mellifera). Bioassays were performed on foragers and newly emerged (24-h-old) bees that received the products mixed in the food. Their survival and behavior were evaluated through the vertical displacement tests and the walk test, analyzed using software Bee-Move. Then, histological analysis of the mesenterium was performed. As control treatment was used sterile water. The honey bees' survival was evaluated for between 1 and 144 h. No interference of B. thuringiensis, Dipel and Xentari, in the survival of Africanized honey bees were found. Only Xentari interfered with vertical displacement behavior of newly emerged (24-h-old) bees. Both the products tested were selective and safe for A. mellifera.

- Abstract
Objective: Considering the importance of dairy farming and the negative effects of heat stress, more tolerant genotypes need to be identified. The objective of this study was to investigate the effect of heat stress via temperature-humidity index (THI) and diurnal temperature variation (DTV) in the genetic evaluations for daily milk yield of Holstein dairy cattle, using random regression models., Methods: The data comprised 94,549 test-day records of 11,294 first parity Holstein cows from Brazil, collected from 1997 to 2013, and bioclimatic data (THI and DTV) from 18 weather stations. Least square linear regression models were used to determine the THI and DTV thresholds for milk yield losses caused by heat stress. In addition to the standard model (SM, without bioclimatic variables), THI and DTV were combined in various ways and tested for different days, totaling 41 models., Results: The THI and DTV thresholds for milk yield losses was THI = 74 (-0.106 kg/d/THI) and DTV = 13 (-0.045 kg/d/DTV). The model that included THI and DTV as fixed effects, considering the two-day average, presented better fit (-2logL, Akaike information criterion, and Bayesian information criterion). The estimated breeding values (EBVs) and the reliabilities of the EBVs improved when using this model., Conclusion: Sires are re-ranking when heat stress indicators are included in the model. Genetic evaluation using the mean of two days of THI and DTV as fixed effect, improved EBVs and EBVs reliability.

- Abstract
Hair follicle cyclical regeneration is regulated by epithelial-mesenchymal interactions. During androgenetic alopecia (AGA), hair follicle stem cells (HFSC) differentiation is impaired by deregulation of dermal papilla cells (DPC) secreted factors. We analyzed androgen influence on BMPs expression in DPC and their effect on HFSC differentiation to hair lineage. Androgens downregulated BMP2 and BMP4 in DPC spheroids. Addition of BMP2 restored alkaline phosphatase activity, marker of hair-inductivity in DPC, and DPC-induced HFSC differentiation, both inhibited by androgens. Concomitantly, in differentiating HFSC, an upregulation of BMPRIa and BMPRII receptors and nuclear β-catenin accumulation, indicative of Wnt/β-catenin pathway activation, were detected. Our results present BMP2 as an androgen-downregulated paracrine factor that contributes to DPC inductivity and favors DPC-induced HFSC differentiation to hair lineage, possibly through a crosstalk with Wnt/β-catenin pathway. A comprehensive understanding of androgen-deregulated DPC factors and their effects on differentiating HFSC would help to improve treatments for AGA., (Copyright © 2020 Elsevier B.V.

- Abstract
Glycosylated flavonoids, caffeoylquinic acid and 3,5-dicaffeoylquinic acid have been identified in the ethyl acetate partition from the crude ethanol extract of Tocoyena bullata (Rubiaceae) leaves. The fraction containing the mixture of flavonol rutin and a tetraglycosylated flavonoid showed 89.2% inhibition and the mixture of isoquercitrin and 3,5-dicaffeoylquinic acid showed 88.5% inhibition of mast cell degranulation. These results demonstrated that the tetraglycosylated flavonoid, rutin, isoquercitrin and 3,5-dicaffeioylquinic acid were the most promising phenolics for inhibition of mast cell degranulation. For the first time the identification of phenolic constituents and their correlation with inhibitory effect on mast cell degranulation were reported in this work.

- Abstract
Objective: To describe and analyze the prognosis of children during the first year of life with a diagnosis of congenital diaphragmatic hernia admitted between the years 2005 and 2015 in the Neonatal Intensive Care Unit., Method: In a retrospective cohort, 129 children with a diagnosis of congenital diaphragmatic hernia were studied. The prognostic factors were analyzed, whereupon prenatal, delivery, and postnatal exposure variables were associated with death during the first year of life. The odds ratio and the confidence interval (95% CI) were calculated for all the studied variables, using the chi-squared test and Student's t-test., Results: The study included 129 children hospitalized from January of 2005 to December of 2015. Seventy-nine (61%) patients died, 50 survived, and 33 had other associated malformations. Among the prognostic factors, the following were significant and increased the chance of death: polyhydramnios (p=0.001), gestational age of the earliest diagnosis (p=0.004), associated congenital abnormalities (OR: 3.013, p=0.022), pO
2 of the first gasometry (p=0.000), pCO2 of the first gasometry (p=0.000), presence of pulmonary hypoplasia (OR: 3.074, p=0.000), use of preoperative vasoactive drugs (OR: 2.881, p=0.000), and use of nitric oxide (OR: 1.739, p=0.000). The presence of only intestines in the hernia content was a protective factor (OR: 0.615, p=0.001)., Conclusion: The mortality in the first year of life in patients with congenital diaphragmatic hernia in this study was 61% in the years 2005-2015. Among the prognostic factors that demonstrated a significant effect, pulmonary hypoplasia had the greatest impact., (Copyright © 2019 Sociedade Brasileira de Pediatria.

- Abstract
Objective: To evaluate the effects of oral health promotion programmes (OHPP) on adolescents' oral health-related quality of life (OHRQoL)., Methods: An electronic search was performed in five databases (MEDLINE via PubMed, Scopus, Virtual Health Library, Web of Science, Cochrane, Grey Literature databases), and specific indexers were used in the manual search. Clinical/community trials, cross-sectional or cohort studies, published in any language, were included. Studies meeting the inclusion criteria were analysed for quality and bias risk., Results: From a total of 2343 abstracts, 4 articles were selected for quality evaluation including 2 studies classified with low, 1 with moderate and 1 with high methodological quality. The qualitative synthesis showed some methodological biases and heterogeneous interventions. Effective OHPP improve OHRQoL. The association of educational and dental care strategies generated greater positive effects on OHRQoL than those related only to treatment or isolated educational practices., Conclusion: Although studies showed positive effects of OHPP on adolescents' OHRQoL, both their shortage and low methodological quality indicates the need for developing other well-designed studies to investigate the present question.

- Abstract
Maternal hypertension may alter physiological parameters, dysregulating the release of hormones such as adipokines, thus influencing the fetal growth course. This study investigated whether hypertensive disorders of pregnancy alter cord blood adipokine levels and correlate these with anthropometric parameters in preterm infants. This is a prospective cohort study with pregnant women < 37-week gestation with and without hypertension and their offspring. Cord blood leptin, adiponectin, and ghrelin were analyzed by LUMINEX®. These adipokines were compared between the groups exposed or not to gestational hypertension using non-parametric statistical tests. The hypertensive pregnancies had significantly higher cord blood leptin (1.00 (IQR 0.67-1.20 ng/mL)) and adiponectin (18.52 (IQR 17.52-25.13 μg/mL)) levels than those without hypertension (0.07 (IQR 0.06-0.08 ng/mL) and 8.13 (IQR 6.50-8.68 μg/mL), respectively, p < 0.0001). The adipokine levels were higher in AGA and SGA infants in the exposed group for both moderate and late preterm. SGA had significantly higher ghrelin levels than the AGA infants. Ghrelin levels were negatively correlated with birth weight (r = - 0.613, p < 0.001), birth length (r = - 0.510, p < 0.001), head circumference (- 0.346, p < 0.002), and gestational age (r = - 0.612, p < 0.001).Conclusions: Our findings demonstrate an increase in adipokine levels in the cord blood of preterm newborn infants exposed to maternal hypertension. What is Known: • Clinical evidence suggests that concentration of the serum adipokines may be affected by risk of hypertension in both adults and pregnant women. • Maternal profile as hypertension alters intrauterine environment and could affect the function of fetal metabolism, impairing fetal growth. What is New: • Gestational hypertension modifies the adipokine profile, with higher rates already present at birth in cord blood samples. • Within the hypertensive group and stratifying for gestation age, ghrelin concentrations were higher in SGA newborns, both in the moderate and late preterm, compared with AGA newborns.

- Abstract
Background: Malignant infarction of the middle cerebral artery (MCA) occurs in a subgroup of patients with ischemic stroke and early decompressive craniectomy (DC) is one of its treatments., Objective: To investigate the functional outcome of patients with malignant ischemic stroke treated with decompressive craniectomy at a neurological emergency center in Northeastern Brazil., Methods: Prospective cohort study, in which 25 patients were divided into two groups: those undergoing surgical treatment with DC and those who continued to receive standard conservative treatment (CT). Functionality was assessed using the modified Rankin Scale (mRS), at follow-up after six months., Results: A favorable outcome (mRS≤3) was observed in 37.5% of the DC patients and 29.4% of CT patients (p=0.42). Fewer patients who underwent surgical treatment died (25%), compared to those treated conservatively (52.8%); however, with no statistical significance. Nonetheless, the proportion of patients with moderate to severe disability (mRS 4‒5) was higher in the surgical group (37.5%) than in the non-surgical group (17.7%)., Conclusion: In absolute values, superiority in the effectiveness of DC over CT was perceived, showing that the reduction in mortality was at the expense of increased disability.

- Abstract
The aim of this study was to evaluate the influence of the Brazilian School Health Program (SHP) on dental clinical disorders such as caries, gingivitis, and dental trauma as well as on the oral-health-related quality of life (OHRQoL) of adolescents in Nova Friburgo, RJ, Brazil. The study consisted of a non-probabilistic (convenience) sample comprising 319 12-year-old adolescents, both participants and non-participants of the SHP, for at least two years. Socio-demographic and OHRQoL questionnaires (CPQ11-14, the Child Perceptions Questionnaire) were applied as well as clinical examinations for caries, periodontal disease, and dental trauma following the World Health Organization (WHO) criteria by calibrated researchers. Mann-Whitney, chi-square tests, and multiple logistic regression models were used for the data analysis. Statistically significant differences were observed between the groups covered and not covered by the SHP for gingivitis (p = 0.0373) and OHRQoL on the social welfare subscale (p = 0.0265) and total scale (p = 0.0449) of CPQ11-14. Multivariate analysis showed that female adolescents were 1.74 times more likely to present a lower OHRQoL (OR = 1.74, 95%IC = 1.10-2.77, p = 0.0183) than males. In addition, non-SHP subjects were 1.56 times more likely to have poor OHRQoL (OR = 1.56, 95%IC = 0.94-2.59, p = 0.0873) than program participants. In conclusion, SHP positively influenced the OHRQoL of adolescents. However, follow-up studies are needed to verify the continued effectiveness of this Brazilian SHP in improving the oral health levels and quality of life of adolescents.

- Abstract
Acute encephalitis is a debilitating neurological disorder associated with brain inflammation and rapidly progressive encephalopathy. Autoimmune encephalitis (AE) is increasingly recognized as one of the most frequent causes of encephalitis, however signs of inflammation are not always present at the onset which may delay the diagnosis. We retrospectively assessed patients with AE associated with antibodies against neuronal surface diagnosed in reference centers in Northeast of Brazil between 2014 to 2017. CNS inflammatory markers were defined as altered CSF (pleocytosis >5 cells/mm
3 ) and/or any brain parenchymal MRI signal abnormality. Thirteen patients were evaluated, anti-NMDAR was the most common antibody found (10/13, 77%), followed by anti-LGI1 (2/13, 15%), and anti-AMPAR (1/13, 7%). Median time to diagnosis was 4 months (range 2-9 months). Among these 13 patients, 6 (46.1%) had inflammatory markers and when compared to those who did not present signs of inflammation, there were no significant differences regarding the age of onset, time to diagnosis and modified Rankin scale score at the last visit. Most of the patients presented partial or complete response to immunotherapy during follow-up. Our findings suggest that the presence of inflammatory markers may not correlate with clinical presentation or prognosis in patients with AE associated with antibodies against neuronal surface. Neurologists should be aware to recognize clinical features of AE and promptly request antibody testing even without evidence of inflammation in CSF or MRI studies.- Published

- Abstract
We examined whether off-season (OffS) and pre-contest (PreC) periods affect blood oxidative stress, inflammatory, immunological, and psychological markers in 20 bodybuilders. The athletes recorded their food intake (3-day record), physical activities, mood states (Profile of Mood States, POMS), recovery-stress (Recovery-Stress Questionnaire for Athletes, RESTQ-Sport), and upper respiratory symptoms (Wisconsin Upper Respiratory Symptom Survey, WURSS-21), and blood was obtained for biochemical analysis. Almost all athletes were in positive energy balance during OffS, while bodybuilders presented markedly restricted energy intake (∼45%) leading to loss of weight (-9%) and fat mass (-45%) with preservation of fat-free mass in PreC. Protein intake was high during both periods, while lipid and carbohydrate intakes were reduced ∼50% in PreC. Almost all athletes consumed 100% of the Recommended Dietary Allowance (RDA) for micronutrients in OffS, while 45% and 75% of the athletes had intakes below the RDA for vitamins A and E in PreC. Oxidative damage to lipids (thiobarbituric acid reactive substances, TBARS), protein carbonyls, and the TBARS/total antioxidant capacity ratio increased in PreC (32%, 27%, 60%), as did plasma tumor necrosis factor α (4-fold) and WURSS-21 scores (25%). There were no significant changes in serum catalase, glutathione reductase, and superoxide dismutase activities nor in interleukin 1β and immunoglobulins. In PreC, POMS showed negative changes in vigor (-20%), fatigue (23%), and total mood disturbance (35%), and RESTQ-Sport showed alterations for general and sport stress (34% and 50%, respectively) and sport recovery (-23%). Thus, PreC negatively affects nutrient intake, which may worsen oxidative stress, inflammation, psychological status, and the severity of respiratory infections in bodybuilders.

- Abstract
Objective: The aim of this study was to evaluate the immunohistochemical expressions of PD1, CD4
+ , and CD8+ in premalignant lesions (OPML) that were transformed into oral squamous cell carcinoma OSCC (OPML-OSCC), in OSCC and also in premalignant lesions that were not transformed into OSCC (OPML-NOSSC)., Materials and Methods: Retrospective analyses were performed in order to verify the demographic characteristics of the patients. CD4, CD8, and PD1 IMH studies were carried out on OPML and OSCC samples from 11 patients with OPML-OSCC and OPML, together with samples from 14 patients with OPML-NOSCC. The differences between OPML-OSCC and OPML-NOSCC were analyzed., Results: Non-homogenous leukoplakia, together with the related oral subsite, and the lack of an exposure to tobacco, were all associated with malignant transformations. There were no statistical differences in the PD1 expression and the CD4+ cells in OPML-OSCC and OPML-NOSCC. A significant increment in the CD8+ cells was noted in the OPML that evolved into carcinomas when compared with OPML-NOSCC (p = 0.05), whereas there were higher CD8+ cells levels in the carcinomas when compared with the OPML that evolved into carcinomas (p = 0.027)., Conclusions: CD8+ cells infiltrate more in OPML-NOSCC than in OPML-OSCC. Carcinoma is more infiltrated by CD8+ cells than its associated OPML., Clinical Relevance: Understanding immunological factors associated with malignant transformation of oral premalignant lesions can open a new way to treat this disease.- Published
