Background: Limited data is available to evaluate the burden of device associated healthcare infections (HAI) [central line associated bloodstream infection (CLABSI), catheter associated urinary tract infection (CAUTI), and ventilator associated pneumonia (VAP)] in low and-middle-income countries. Our aim is to investigate the population attributable mortality fraction and the absolute mortality difference of HAI in a broad population of critically ill patients from Brazil., Methods: Multicenter cohort study from September 2019 to December 2023 with prospective individual patient data collection. VAP, CLABSI, and CAUTI were diagnosed by each center in accordance with Brazilian regulatory agency guidance. If a patient fulfilled all diagnostic criteria, he was deemed to have Confirmed HAI. An adjusted disability multistate model was used to evaluate the population attributable in-hospital mortality fraction (PAF) and the absolute in-hospital mortality difference (AMD)., Results: A total of 128,247 patients were included. 4066 (3.2%) distinct patients had at least one diagnosis of HAI (1493 CLABSI, 433 CAUTI, 2742 VAP, and 435 patients with more than one HAI) during the ICU stay. The PAF was 3.89% (95% CI 3.68-4.11%) for HAI, 2.16% (2.05-2.33%) for VAP, 1.2% (1.08-1.32%) for CLABSI, 0.11% (0.07-0.16%) for CAUTI, and 0.33% (0.26-0.4%) for ≥ 2 HAI. The AMD for HAI was 33.69% (95% CI 32.27-35.33%), 29.01% (27.15-30.98%) for VAP, 31.64% (29.3-34.81%) for CLABSI, 9.94% (3.88-15.54%) for CAUTI and 35.6% (28.93-42.99%) for ≥ 2 HAI., Conclusions: Device-associated HAI significantly contribute to hospital mortality and impose a high excess risk of death for critically ill patients., Competing Interests: Declarations.

Carbonaceous aerosols (CA), composed of black carbon (BC) and organic matter (OM), significantly impact the climate. Light absorption properties of CA, particularly of BC and brown carbon (BrC), are crucial due to their contribution to global and regional warming. We present the absorption properties of BC (b Abs,BC ) and BrC (b Abs,BrC ) inferred using Aethalometer data from 44 European sites covering different environments (traffic (TR), urban (UB), suburban (SUB), regional background (RB) and mountain (M)). Absorption coefficients showed a clear relationship with station setting decreasing as follows: TR > UB > SUB > RB > M, with exceptions. The contribution of b Abs,BrC to total absorption (b Abs ), i.e. %Abs BrC , was lower at traffic sites (11-20 %), exceeding 30 % at some SUB and RB sites. Low AAE values were observed at TR sites, due to the dominance of internal combustion emissions, and at some remote RB/M sites, likely due to the lack of proximity to BrC sources, insufficient secondary processes generating BrC or the effect of photobleaching during transport. Higher b Abs and AAE were observed in Central/Eastern Europe compared to Western/Northern Europe, due to higher coal and biomass burning emissions in the east. Seasonal analysis showed increased b Abs , b Abs,BC , b Abs,BrC in winter, with stronger %Abs BrC , leading to higher AAE. Diel cycles of b Abs,BC peaked during morning and evening rush hours, whereas b Abs,BrC , %Abs BrC , AAE, and AAE BrC peaked at night when emissions from household activities accumulated. Decade-long trends analyses demonstrated a decrease in b Abs , due to reduction of BC emissions, while b Abs,BrC and AAE increased, suggesting a shift in CA composition, with a relative increase in BrC over BC. This study provides a unique dataset to assess the BrC effects on climate and confirms that BrC can contribute significantly to UV-VIS radiation presenting highly variable absorption properties in Europe., 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.

Objective: To explore the relationship between parenting styles and children's personality traits and parental-reported sleep bruxism (SB)., Methods: A total of 301 parents/caregivers of Brazilian children participated in this cross-sectional study and answered an online questionnaire addressing sociodemographic characteristics, sleep-related behaviors and parent-reported SB. The Brazilian versions of the Parenting Styles and Dimensions Questionnaire and the Eysenck Personality Questionnaire-Junior assessed children's parenting styles and personality traits. Descriptive analysis and multinomial logistic regression were used., Results: Boys (OR=2.07; 95% CI=1.09-3.91) whose snoring (OR=2.98; 95% CI=1.55-5.73) were associated with mild parent-reported SB. Boys (OR=2.61; 95% CI=1.20-5.70) and high levels of neuroticism (OR=2.27; 95% CI=1.06-4.860) were associated with moderate/severe parent-reported SB. Authoritarian parenting attitudes decreased the likelihood of moderate/severe parent-reported SB (OR=0.37; 95% CI=0.16-0.86)., Conclusions: Parents/caregivers who exhibited more authoritarian attitudes reported a lower prevalence of moderate/severe children SB. Neuroticism trait and snoring influenced the severity of parent-reported SB.

Objectives: to develop and analyze evidence of content validity of a checklist for training nurses in measuring bladder volume through ultrasound., Methods: a methodological study, consisting of three stages: literature review; instrument item preparation; and analysis of evidence of content validity. The Content Validity Index (CVI) and Gwet's AC2 were used for content validity analyses., Results: the checklist consisted of 23 items. The CVIs for clarity, relevance and dimensionality were 0.99, 0.99 and 0.98 respectively, and the CVIs for Gwet's AC2 with coefficients for clarity, relevance and dimensionality were 0.89, 0.97 and 0.95, respectively, with p<0.001., Conclusions: the checklist developed for training nurses in measuring bladder volume through ultrasound achieved adequate evidence of content validity, and can be used to train nurses in clinical practice and future research.

With the increase in digitalization of adolescents and health services, the population must demonstrate digital health literacy skills to be able to navigate online health information, as well as identify, evaluate, and apply relevant information. The present study aimed to investigate the psychometric properties of the adapted version of the eHealth Literacy Scale (eHEALS-BrA) for Brazilian adolescents. This study was conducted between September 2022 and May 2023, involving a total of 260 adolescents aged 13 to 19, with a mean age of 15.64 years (SD = 1.84), all of whom were enrolled in public schools in Brazil. Structural validity was evaluated by confirmatory factor analysis (CFA). The reliability of the instrument was assessed using Cronbach's alpha (α) and McDonald's omega (ω), and test-retest reliability. Questionnaires about sociodemographic aspects, health-related characteristics, and internet use were administered and used as discriminant validation measures. Convergent Validity was determined by correction with the domains of the World Health Organization Quality of Life-Bref (WHOQOL-Bref) instrument. For test-retest reliability, 67 participants completed the eHEALS-BrA a fortnight later. The average eHEALS-BrA score was 28.05 points (SD = 5.05). CFA revealed that the model with the best fit had a single factor (χ2 = 49.884 [df = 20, p = 0.0002], CFI = 0.934, TLI = 0.908, RMSEA = 0.076(CI:0.05-0.10), and SRMR = 0.045). The instrument demonstrated good reliability, with satisfactory internal consistency (α and ω = 0.71) and stability (ICC = 0.82, 95% CI:0.70-0.89). The eHEALS-BrA was correlated with the physical, psychological, and environmental domains of the WHOQOL-Bref (p = 0.001) (convergent validity). Higher scores were found among male adolescents, individuals who practiced physical activity, those with better self-rated health, those who considered the internet useful for searching for health information (discriminant validity), and those with better self-rated skills related to using the internet (convergent validity) (p < 0.05). The eHEALS-BrA demonstrated adequate psychometric properties for measuring digital health literacy in Brazilian adolescents., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Barbosa et al.

Adverse childhood experiences (ACEs) can be extremely traumatic, and their impact on health throughout the life course has been a public policy issue all around the world. Oral health conditions significantly influence quality of life, but its relationship with ACEs among children and adolescents is not well defined. This systematic review investigated the association between ACEs and oral health outcomes in children and adolescents. The search was conducted across six databases and the gray literature, with no restrictions. It included studies evaluating the association between ACEs and oral health outcomes (oral health condition, utilization of dental services, oral hygiene habits, or oral health related to quality of life) in individuals aged 0 to 19. Data of included studies were extracted and methodological quality was assessed. Meta-analysis was used for quantitative synthesis, and the Grading of Recommendations Assessment, Development and Evaluation approach assessed evidence certainty. From the 12 included studies, 11 had a cross-sectional design, and 1 was a cohort study. Seventeen types of ACEs were investigated, including neglect; violence between parents or caregivers; alcohol and substance abuse; and peer, community, and collective violence. The methodological quality compliance ranged between 38% and 100%. The meta-analysis revealed associations between ACEs and lower use of dental services, toothache, gingival bleeding, and dental cavities. Cumulative exposure to more than three ACEs was associated with poorer oral health. The certainty of the evidence varied from low to very low. These results highlight that children and adolescents with ACEs are more likely to present higher oral health problems, including decreased use of dental services., 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.

Pelargonium sidoides DC. (Geraniaceae) is a widely recognized medicinal plant whose natural extract exhibits therapeutic effects through a multi-target approach. Existing literature encompasses investigations of antimicrobial and cellular effects, including clinical trials. A comprehensive review is required to summary the substantial number of published investigations and to grasp the potentialities of this extract. The aim of this scoping review was to provide an overview of the antimicrobial, antiadhesive, immunomodulatory, and respiratory effects of the P. sidoides extract, along with a discussion of its mechanism of action, clinical safety, potential repurposing uses, and areas requiring further investigation. A systematic search of Medline (PubMED) and Scopus databases was conducted using the terms: EPs7630, Pelargonium , Pelargonium sidoides . The search process was finished on 5th, June 2024. Two researchers screened titles and abstracts according to the eligibility criteria, which included in vitro , in vivo , randomized, and non-randomized clinical trials. Out of 4367 publications identified, 134 studies were included in this review. A structured form was applied for data extraction. PRISMA-ScR was used to guide reporting of this review. Most of the studies were conducted in vitro , followed by human studies and animal models. The findings demonstrated a strong and broad-spectrum antimicrobial and antiadhesive effect against various bacterial, fungi, and virus species. Additionally, a strong immunomodulatory effect was observed, including the induction of pro-inflammatory cytokines during infection, and modulation of other immune response components. The effects on the respiratory system have been extensively examined, showing remarkable clinical efficacy against both bacterial and viral infections with no significant cytotoxicity or adverse effects. Furthermore, recent research showed an anti-COVID effect by direct antiviral and immunomodulation mechanisms. Nonetheless, the establishment of a concentration protocol to further studies is still challenging due to variations in extract origin, composition and extraction methods. In this sense, the use of a commercial extract such as EPs® 7630 is of great value to facilitate the standardization of the tested protocols. The noteworthy anti-infective potential of P. sidoides extract lies in its multifaceted mechanism of action, which encompasses direct microbicidal effects and modulation of the immune response. These unique properties establish P. sidoides extract as a promising alternative in the war against a wide range of infectious diseases., Competing Interests: 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., (© 2024 The Authors.)

Background: Heart failure (HF) imposes significant disability. The World Health Organization Disability Assessment Schedule (WHODAS) 2.0 is a generic instrument that measures disability. Although it has been used in HF, no previous study has investigated its measurement properties in this group., Objective: To assess the test-retest reliability, internal consistency, convergent, and discriminant validity of WHODAS 2.0 in individuals with HF., Methods: We conducted a cross-sectional study that included individuals with HF treated at the outpatient cardiology center. Data included sociodemographic and clinical (e.g., New York Heart Association - NYHA) characteristics, estimated functional capacity (Duke Activity Status Index - DASI), quality of life (Minnesota Living with Heart Failure Questionnaire - MLHFQ), and disability (the WHODAS 2.0 36-item version). We assessed associations, using Pearson's correlation coefficient or the Kruskal-Wallis test, between the WHODAS 2.0 scores and the MLHFQ, DASI, and NYHA. The WHODAS 2.0 results were collected again seven days after the initial assessment for reliability (intraclass correlation coefficient - ICC)., Results: Participants were 100 people with HF (M age = 57.8 ± 14 years, 57 % men), of whom 84 % were literate. The WHODAS 2.0 was reliable (ICC = 0.789) and had good internal consistency (Cronbach's alpha >0.7 in all domains). Convergent validity was observed through moderate correlations with DASI and MLHFQ and discriminant validity with statistically different results according to NYHA classes., Conclusion: WHODAS 2.0 is a reliable, consistent, and valid instrument for measuring disability in individuals with HF. Further research is needed to evaluate other properties, such as its responsiveness to interventions., Competing Interests: Declaration of competing interest None of the other authors have any conflict of interest to disclose., (Copyright © 2024.

Objective: To test the association between socioeconomic and sociodemographic status of Brazilian dental students with discriminatory experiences suffered by them., Methods: This multicenter cross-sectional study was conducted with 531 undergraduate dental students from four different Brazilian states. The Explicit Discrimination Scale (EDS) was used to measure the experience of discrimination in several daily situations. A questionnaire about sociodemographic and socioeconomic characteristics, form of admission, and permanence in dental schools was developed and validated by experts and six dental students through cognitive interviews. The EDS and questionnaire were sent to students by an online platform using snowball sampling. Descriptive analysis, bivariate tests, and multiple Poisson regression were performed., Results: Among the participants, most were female, white, heterosexual, and cisgender. The mean EDS total score was higher among those students who used Brazilian Affirmative Actions for higher education access and permanence (p < 0.005). The multiple analysis indicated that students who were black (prevalence ratio [PR] = 1.484; 95% confidence interval [95%CI]: 1.291-1.705), women (PR = 1.227; 95%CI: 1.030-1.462), had lower monthly income (PR = 1.212; 95%CI: 1.043-1.409) and were lesbian, gay, bisexual, transgender, intersex, queer, pansexual, and plus (LGBTQIAP+) (PR = 1.466; 95%CI: 1.238-1.735) showed a higher probability of discriminatory experiences when compared to white, male and heterosexual students with higher monthly income., Conclusion: There is a racial and social class pattern among dental students. The exclusionary factors such as black race, female gender, lower monthly income and being LGBTQIAP+ make students more vulnerable to discriminatory experiences., (© 2024 American Dental Education Association.)

Purpose: To investigate the perceptions of parents/caregivers about the impact of oral conditions on the oral health-related quality of life (OHRQoL) of children/adolescents with autism spectrum disorder (ASD) compared to the perceptions of parents/caregivers of children/adolescents without ASD., Methods: A comparative cross-sectional study was conducted involving 80 children/adolescents with ASD three to 16 years of age matched by sex and age with 80 children/adolescents without ASD and their parents/caregivers. Clinical examinations were performed for the diagnosis of dental caries experience (DMFT/dmft), clinical consequences of untreated dental caries (PUFA/pufa), visible plaque (VPI), bleeding on probing (BPI), malocclusion and traumatic dental injury (TDI). Parents/caregivers answered a questionnaire addressing sociodemographic characteristics and the Brazilian version of the Parental-Caregiver Perceptions Questionnaire (P-CPQ), which measures OHRQoL from the perspective of parents/caregivers. Data analysis involved the Wilcoxon test, chi-squared test and Poisson regression., Results: Dental caries experience impacted OHRQoL in the group with ASD regarding the total P-CPQ score (p < 0.001) as well as the "oral symptoms" (p = 0.011) and "wellbeing" (p < 0.011) domains. No differences were found between the perceptions of parents/caregivers of children/adolescents with ASD and perceptions of parents/caregivers of children/adolescents without ASD (p = 0.721)., Conclusion: Dental caries experience can have a negative impact on the OHRQoL of children/adolescents with ASD., (© 2023.

Objective: To assess the impact of treatment with orthodontic aligners (OA) on oral health-related quality of life (OHRQoL) in patients with trisomy 21 (T21) compared to non-syndromic patients., Materials and Methods: The sample consisted of 30 patients, both sexes, aged between 11 and 35 years, divided into two groups: T21 (n = 10, patients with T21, treated prospectively) and CONTROL (n = 20, control group, non-syndromic patients, from the Orthodontic Laboratory of UNOPAR). In both groups, patients were treated with Invisalign orthodontic aligners (Align Technology), following the same treatment parameters. Participants, assisted by their caregivers, when necessary, answered Oral Health Impact Profile (OHIP-14) instrument and the patient's guardians answered the Oral Health Scale for People with Down's syndrome (OHDS) instrument, before (T0) and after 30 (T1), 180 (T2), and 365 (T3) days from the start of treatment. Friedman tests with Bonferroni correction and Mann-Whitney tests were used (p < .05)., Results: For the OHDS instrument, it was observed that for the eating and communication domains and an overall score, the treatment with OA positively impacted the lives of T21 patients (p < .05). Regarding the OHIP-14 instrument, the intragroup evaluation showed that in the CONTROL group, there was no significant difference between the evaluated times; while for the T21 group, there was a significant positive impact (p < .05)., Conclusion: The results showed that the treatment with aligners positively impacted the OHRQoL of T21 patients, and these results were perceived by caregivers, mainly in relation to issues related to eating and communication., (© 2024 Special Care Dentistry Association and Wiley Periodicals LLC.)

Background: Cardiopulmonary exercise testing (CPET) is the gold standard for functional capacity assessment, although it is costly and not easily accessible. The Glittre-ADL test may be a low-cost alternative for patients with heart failure., Objective: To establish a cutoff point for functional capacity of patients with heart failure using the Glittre-ADL test. We also assessed agreement, reliability, and minimal detectable change., Methods: This cross-sectional study was conducted with 78 patients (aged 21 to 65 years) with heart failure and reduced ejection fraction (functional classes II and III of the New York Heart Association). Test-retest reliability was measured using the intraclass correlation coefficient (ICC), while receiver operating characteristic (ROC) curves were used to determine whether ADL-time, could distinguish between patients with peak oxygen consumption (VO 2peak ) < 16 versus those ≥ 16 ml/kg/min., Results: A cutoff point of 255 s (76 % sensitivity [95 % CI 58, 89] and 72 % specificity [95 % CI 56, 85]) was established based on the total time spent on Glittre-ADL test; the area under the curve was 0.773 (95 % CI 0.663, 0.861; p < 0.0001). Regarding agreement, a significant correlation was found between test and retest (r = 0.83, r 2 = 0.69, p < 0.001). Intraclass correlation coefficient, absolute reliability, and minimal detectable change were 0.84 (95 % CI 0.45, 0.94; p < 0.001), 3.2 %, and 8.8 % (23.1 s), respectively., Conclusion: Glittre-ADL test showed good reproducibility in repeated tests. Thus, the cutoff point established by our study can be used in clinical practice instead of CPET to identify patients with severe heart failure., Competing Interests: Declaration of competing interest All authors declare that they have no conflicts of interest., (Copyright © 2024 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia.

This study evaluated the psychometric properties of the Portuguese version of Digital Health Literacy Instrument for Brazilian Adolescents (DHLI-BrA). Two hundred and sixty Brazilian adolescents answered the DHLI-BrA and the Brazilian version of quality-of-life and health literacy instruments: WHOQOL-Bref, eHEALS-BrA, NVS-BR, and REALMD-20. Then, they answered a questionnaire on sociodemographics, health, Internet access, and digital health aspects. The data collection was conducted between September and December of 2022.The statistical test assessed internal consistency, stability, discriminant and convergent validities, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA). Item response theory (IRT) analysis using 2PL was applied to performance-based DHLI-BrA. The DHLI-BrA self-reported questions demonstrated almost perfect internal consistency (α and ω = 0.83) and good stability (ICC = 0.906; 95% CI: 0.75-0.95). In EFA and CFA, the best-adjusted model was composed of six factors (χ 2 = 229.173 (df = 174, p = 0.003), CFI = 0.944, TLI = 0.933, RMSEA = 0.035, and RMSR = 0.047). The performance-based DHLI-BrA demonstrated moderate internal consistency (α = 0.57 and KR20 = 0.56) and good stability (ICC = 0.86, 95% CI: 0.76-0.92). In EFA and CFA, the best-adjusted model was composed of a single factor (χ 2 = 17.901 (df = 14, p = 0.2113), CFI = 0.952, TLI = 0.927, RMSEA = 0.033, and RMSR = 0.038). IRT analyses revealed item discrimination ranging from -0.71 to 1.83 and difficulty from -1.53 to 1.02. Convergent validity of the self-reported DHLI-BrA was obtained by its correlation with the eHEALS-BrA (r = 0.45) and REALMD-20 (r = 0.19), besides the performance-based DHLI-BrA with its correlation with the NVS (r = 0.47) and REALMD-20 (r = 0.44). The DHLI-BrA demonstrated adequate psychometric properties to measure the self-reported, performance-based digital health literacy of Brazilian typically developing adolescents.

Physical activity (PA) improves dyspnoea, psychological wellbeing and quality of life (QoL) for people with COPD reducing their risk of exacerbation. However, engagement in PA is low especially amongst those with anxiety and depression, and PA programmes are limited in countries with limited resources such as Brazil. We explored perceptions of 21 people with COPD about the impact of their disease on taking part in community-based PA programmes in Sao Paulo, Brazil through semi-structured telephone interviews from October 2020 to April 2021. Discussions were audio-recorded, transcribed, and analysed using the Framework method. Five themes were identified: Knowledge about COPD and its management; Self-perception of life with COPD; Knowledge and experiences of depression and anxiety; Opinions on PA and repercussions of COVID-19. PA was considered to be important in bringing physical and mental health benefits but there were barriers in accessibility of formal PR programmes and therefore local community PA programmes were considered to be important. People with mental health conditions tended to view PA more negatively. COVID-19 had reduced PA opportunities, access to COPD treatment and social interaction, and was associated with more exacerbations and emotional suffering. In general, this study showed an urgent need to improve knowledge about COPD and its risk factors and management among both patients, the public and primary healthcare professionals. We provide important content for the formulation of public policies for the implementation of specific activity programmes for people with COPD in community spaces using local resources and intersectoral partnerships., (© 2024.

Background and Aims: Ovum pick-up (OPU) is an intrinsic step of in vitro fertilization procedures. Nevertheless, it can cause ovarian lesions and compromise female fertility in bovines. Recently, we have shown that intraovarian injection of adipose-derived mesenchymal stromal cells (AD-MSCs) effectively preserves ovarian function in bovines. Given that MSC-derived extracellular vesicles (MSC-EVs) have been shown to recapitulate several therapeutic effects attributed to AD-MSCs and that they present logistic and regulatory advantages compared to AD-MSCs, we tested whether MSC-EVs would also be useful to treat OPU-induced lesions., Methods: MSC-EVs were isolated from the secretome of bovine AD-MSCs, using ultrafiltration (UF) and ultracentrifugation methods. The MSC-EVs were characterized according to concentration and mean particle size, morphology, protein concentration and EV markers, miRNA, mRNA, long noncoding RNA profile, total RNA yield and potential for induction of the proliferation and migration of bovine ovarian stromal cells. We then investigated whether intraovarian injection of MSC-EVs obtained by UF would reduce the negative effects of acute OPU-induced ovarian lesions in bovines. To do so, 20 animals were divided into 4 experimental groups (n = 5), submitted to 4 OPU cycles and different experimental treatments including vehicle only (G1), MSC-EVs produced by 7.5 × 10 6 AD-MSCs (G2), MSC-EVs produced by 2.5 × 10 6 AD-MSCs (G3) or 3 doses of MSC-EVs produced by 2.5 × 10 6 AD-MSCs, injected after OPU sessions 1, 2 and 3 (G4)., Results: Characterization of the MSC-EVs revealed that the size of the particles was similar in the different isolation methods; however, the UF method generated a greater MSC-EV yield. MSC-EVs processed by both methods demonstrated a similar ability to promote cell migration and proliferation in ovarian stromal cells. Considering the higher yield and lower complexity of the UF method, UF-MSC-EVs were used in the in vivo experiment. We evaluated three therapeutic regimens for cows subjected to OPU, noting that the group treated with three MSC-EV injections (G4) maintained oocyte production and increased in vitro embryo production, compared to G1, which presented compromised embryo production following the OPU-induced lesions., Conclusions: MSC-EVs have beneficial effects both on the migration and proliferation of ovarian stromal cells and on the fertility of bovines with follicular puncture injury in vivo., Competing Interests: Declaration of competing interest Authors MP and PM declare competing financial interests as owners of the company Bio.

The aim of this study was to undertake a cross-cultural adaptation of the eHealth Literacy Scale (eHEALS) instrument to measure digital health literacy of Brazilian adolescents. eHEALS is a scale consisting of 8 items that measure self-perception related to the consumption of electronic health information. This is a methodological study of cross-cultural adaptation, conducted out from February 2022 to June 2022. The following steps were carried out: a) assessment and adequacy of cultural equivalence by a committee of experts; b) back-translation; c) synthesis of back-translations; d) cognitive testing with 42 Brazilian adolescents, using cognitive interviews with probing questions. All items that were difficult to understand were adapted to the (language) context of Brazilian adolescents. Cronbach's alpha coefficient for eHEALS-BrA was 0.81 and, if one of the items were excluded from the instrument, it ranged from 0.75-0.81. This version of the eHEALS proved to be culturally well-adapted to the context of Brazilian adolescents, and has the potential to measure digital health literacy in this population after having its validation confirmed through psychometric analyses.

Background: Critically ill patients are at increased risk of health care-associated infections due to various devices (central line-associated bloodstream infection, catheter-associated urinary tract infection, and ventilator-associated pneumonia), which pose a significant threat to this population. Among several strategies, daily bathing with chlorhexidine digluconate, a water-soluble antiseptic, has been studied as an intervention to decrease the incidence of health care-associated infections in the intensive care unit; however, its ability to reduce all health care-associated infections due to various devices is unclear. We designed the Daily Chlorhexidine Bath for Health Care Associated Infection Prevention (CLEAN-IT) trial to assess whether daily chlorhexidine digluconate bathing reduces the incidence of health care-associated infections in critically ill patients compared with soap and water bathing., Methods: The CLEAN-IT trial is a multicenter, open-label, cluster randomized crossover clinical trial. All adult patients admitted to the participating intensive care units will be included in the trial. Each cluster (intensive care unit) will be randomized to perform either initial chlorhexidine digluconate bathing or soap and water bathing with crossover for a period of 3 to 6 months, depending on the time of each center's entrance to the study, with a 1-month washout period between chlorhexidine digluconate bathing and soap and water bathing transitions. The primary outcome is the incidence of health care-associated infections due to devices. The secondary outcomes are the incidence of each specific health care-associated infection, rates of microbiological cultures positive for multidrug-resistant pathogens, antibiotic use, intensive care unit and hospital length of stay, and intensive care unit and hospital mortality., Conclusion: The CLEAN-IT trial will be used to study feasible and affordable interventions that might reduce the health care-associated infection burden in critically ill patients.

Objective: To analyze longitudinality in the production of care in Family Health from the perspective of users., Method: Qualitative research carried out with 18 users of a family health unit in a municipality in the state of São Paulo. The data was produced through semi-structured interviews and the empirical material was analyzed by interpreting the meanings in the light of the theoretical framework of continuity of care and longitudinality., Results: 22 ideas were identified and grouped into three meanings: organization and operationalization of work in the family health unit, self-care and the health system. The first highlighted elements of organizational constraints, workforce, hard and soft technologies. The second direction pointed to the user's co-responsibility for their health condition and lifestyle, making it possible to recognize longitudinality as: discontinuous or focused and continuous or extended. And in the third meaning, the understanding of the functioning of the three levels of care was presented with structural and technological demarcations., Conclusion: The users recognized potential and weaknesses in the three meanings referring to the constituent elements of the theoretical framework. Family Health is capable of offering continuous or extended longitudinality, even in a municipality with low coverage of the strategy. However, this scenario can weaken the process of developing the attribute from this perspective, as it limits access to other levels of care and compromises its structuring elements and dimensions and, consequently, the continuity of care.

Introduction: Little is known regarding the impact of dental treatment under sedation on distressed young children's oral health-related quality of life (OHRQoL)., Aim: To evaluate the impact of dental treatment under sedation on the OHRQoL of children and their families., Methods: Caregivers of two-to-six-year-old children answered the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS): (1) before treatment under sedation (T0), (2) two weeks (T1) and (3) 3 months after the completion of treatment (T2). A global transition judgment was included in the posttreatment evaluations to determine the perception of changes in OHRQoL after dental treatment. Bivariate analysis was performed. Changes in scores and effect sizes (ES) were calculated., Results: Reductions were found at both posttreatment evaluations in the total B-ECOHIS scores (median [25th-75th percentile] at T0: 14 [9.8-21.7]; T1: 2.0 [0.0-5.1]; T2: 2.0 [0.0-6.7]); "child impact" section (T0: 8.8 [4.0-13.1]; T1: 0.0 [0.0-2.2]; T2: 0.0 [0.0-4.3]) and "family impact" section (T0: 6.0 [4.0-8.5]; T1: 0.0 [0.0-2.0]; T2: 0.0 [0.0-2.0]) (≤0.001; large ES). In 92.3% of cases at T1 and 88.3% at T2, caregivers reported that their child's oral health improved considerably., Conclusion: Dental treatment under sedation significantly improved the OHRQoL of the children and their families., (© 2024 Special Care Dentistry Association and Wiley Periodicals LLC.)

Background: The risk of death due to tuberculosis (TB) in Brazil is high and strongly related to living conditions (LC). However, epidemiological studies investigating changes in LC and their impact on TB are lacking., Objectives: To evaluate the impact of LC on TB mortality in Brazil., Design and Setting: This ecological study, using panel data on spatial and temporal aggregates, was conducted in 1,614 municipalities between 2002 and 2015., Methods: Data were collected from the Mortality Information System and the Brazilian Institute of Geography and Statistics. The proxy variable used for LC was the Urban Health Index (UHI). Negative binomial regression models were used to estimate the effect of the UHI on TB mortality rate. Attributable risk (AR) was used as an impact measure., Results: From 2002 to 2015, TB mortality rate decreased by 23.5%, and LC improved. The continuous model analysis resulted in an RR = 0.89 (95%CI = 0.82-0.96), so the AR was -12.3%. The categorized model showed an effect of 0.92 (95%CI = 0.83-0.95) in municipalities with intermediate LC and of 0.83 (95%CI = 0.82-0.91) in those with low LC, representing an AR for TB mortality of -8.7% and -20.5%, respectively., Conclusions: Improved LC impacted TB mortality, even when adjusted for other determinants. This impact was greater in the strata of low-LC municipalities.

Purpose: To associate maternal anxiety with sociodemographic factors, breastfeeding practices, oral habits, and the child's entry into daycare among deaf and hearing (non-deaf) mothers., Methods: This retrospective comparative cross-sectional study included 116 mothers (29 deaf and 87 hearing) of children aged between two and five years. Deaf mothers belonged to a reference center in the city, while hearing mothers were contacted in public daycares where their children were enrolled. Mothers underwent interviews covering socio-economic factors and child development-related aspects. Additionally, they completed the Brazilian Beck Anxiety Inventory, adapted for both deaf and hearing individuals, serving as instruments to assess anxiety. The Kolmogorov-Smirnov normality test, Kruskal Wallis test, Mann-Whitney test, and Poisson Regression were employed for statistical analyses (p<0.05)., Results: Deaf mothers exhibited anxiety scores one and a half times higher than hearing mothers. Moreover, mothers of children with thumb-sucking habits showed higher anxiety scores, while mothers whose children started attending daycare as infants demonstrated lower anxiety scores compared to mothers of children without such habits and who did not attend daycare., Conclusion: Deaf mothers displayed higher anxiety levels when compared to hearing mothers. Children's behaviors, such as thumb-sucking habits, and early enrollment in daycare during the first year of life influenced maternal anxiety.

The purpose of this study was to characterize the activity of essential oils from Nepeta Cataria (EON) at concentrations of 125 μ L  L-1, 150 μ L  L-1, 175 μ L  L-1, and 200 μ L  L-1 on the behavior of loss of the posture reflex and recovery of the posture reflex and electrocardiographic activity and recording of the opercular beat of Colossoma macropomum during immersion bathing for a period of 5 min, in order to obtain a window for safe use during anesthesia. The fish (23.38 ± 3.5 g) were assigned to the following experiments: experiment 1 (latency to loss and recovery of the posture reflex): (a) 125 μ L  L-1, (b) 150 μ L  L-1, (c) 175 μ L  L-1, and (d) 200 μ L  L-1 (n = 9) per group. Experiment 2 (electrocardiographic and heartbeat recordings): (a) control group; (b) vehicle control group (2 ml of alcohol per liter of water), (c) 125 μ L  L-1, (d) 150 μ L  L-1, (e) 175 μ L  L-1, and (f) 200 μ L  L-1 (n = 9), per group. All the concentrations used showed efficacy in inducing loss of the posture reflex and reversibility with recovery of the posture reflex, but the electrocardiographic recordings indicated morphographic changes such as bradycardia during induction and p wave apiculation during recovery at the highest concentrations tested. In this way, we suggest a safe use window for short-term anesthesia with EON in the concentration range of 125 to 150 μ L  L-1 for juvenile Colossoma macropomum., (© 2024.

Objective: Investigate individual and contextual determinants associated with traumatic dental injuries in schoolchildren., Methods: A cross-sectional study with 739 pairs of parents and children. Parents answered a sociodemographic questionnaire, the Family Adaptability and Cohesion Evaluation Scale and a questionnaire on the child's use of electronic devices. Examinations of the children were conducted at the school by calibrated examiners using the diagnostic criteria proposed by Andreasen. Contextual variables of the school were also collected. Multilevel Poisson regression for complex samples was performed (p < 0.05)., Results: The individual factors associated with the outcome were children of single parents (PR = 2.33; 95% CI: 1.79-2.66), practice of sports (PR = 2.46; 95% CI: 1.70-3.22), the daily use of electronic devices (PR = 1.78; 95% CI: 1.31-1.81), more than 2 h per day of screen time (PR = 3.84; 95% CI: 1.94-4.28) and chaotic family adaptability (PR = 4.22; 95% CI: 3.44-4.99). The contextual variables were studying at a public school (PR = 1.77; 95% CI: 1.02-3.05) and the presence of rigid floor in the school courtyard (PR = 1.99; 95% CI: 1.15-3.15)., Conclusion: Individual determinants, studying at a public school and the presence of rigid floor in the school courtyard were associated with traumatic dental.

Background/aim: Traumatic dental injuries (TDI) constitute a public health problem. The aim of the present study was to investigate whether sleep disorders, school jet lag, and anxiety are associated with TDI in schoolchildren 8-10 years of age., Methods: An analytical, cross-sectional study was conducted with 739 pairs of parents/guardians and children enrolled in public and private schools. The parents/guardians answered a socioeconomic questionnaire, the Sleep Disturbance Scale for Children, Circadian Energy Scale, and Revised Children's Manifest Anxiety Scale. Four examiners underwent calibration exercises for the diagnosis of TDI (K > 0.80) using the criteria proposed by Andreasen (2007). A directed acyclic graph was used for the formulation of the theoretical model and statistical adjustments. Unadjusted and adjusted robust binary logistic regression analyses were performed (α = 5%)., Results: The prevalence of TDI was 16.2%. The following variables remained associated with the outcome in the final model: family income less than or equal to the minimum monthly wage (OR = 1.77; 95% CI: 1.09-2.88; p = .02), child's height >137.6 cm (OR = 1.68; 95% CI: 1.06-2.64; p = .02), the occurrence of school jet lag (OR = 2.12; 95% CI: 1.27-3.53; p = .004), anxiety (OR = 1.77; 95% CI: 1.04-3.00; p = .04) and sleep disorders (OR = 1.63; 95% CI: 1.38-1.93; p = .05)., Conclusion: Children from families with a lower income, taller children, those with school jet lag, those with anxiety and those with sleep disorders had a greater occurrence of TDI., (© 2023 John Wiley & Sons A/S.

Hypertrophic cardiomyopathy in children has diverse causes. Mitochondrial diseases, a rare aetiology leading to cardiomyopathy in 20-40% of affected children, predominantly present as hypertrophic cardiomyopathy. Diagnosis is challenging due to inconsistent genotype-phenotype correlation, resulting in various clinical presentations. We present a case of a one-month-old infant with severe hypertrophic cardiomyopathy and cardiac tamponade. Genetic diagnosis revealed a Valyl-tRNA synthetase 2 (VARS2) gene mutation, linking it to mitochondrial encephalopathy-cardiomyopathy. This case highlights novel variants and expands the understanding of hypertrophic cardiomyopathy aetiology in infants.

Aim: This study aims to validate a Perceived Social Support Scale for University Students (EPSSEU) during periods of social restrictions, by focusing on family and university support., Subject and Methods: This cross-sectional study was conducted with undergraduate students from a public higher education institution. The college students who participated in the study-1353 at baseline and 378 after 6 months-answered a virtual questionnaire containing questions on: sociodemographic and lifestyle data, items proposed for the EPSSEU, Satisfaction with Social Support Scale (ESSS), and Depression, Anxiety and Stress Scale (DASS-21). Exploratory factor analysis, Cronbach's alpha reliability analysis, as well as discriminant, convergent, and known-group validations were performed., Results: The results showed two factors support from: i) the university and ii) friends and family- which explained 61.82% of the variance in the data. The EPSSEU showed good reliability (Cronbach's alpha = 0.796) as well as validity, with higher scores among individuals without depression, anxiety, or stress., Conclusion: The EPSSEU shows adequate psychometric qualities and may be a useful instrument for assessing university students' social support in pandemics, social distancing, and remote teaching contexts., (© 2024.

The aim of this study was to identify and describe the characteristics of coronavirus (COVID-19)-disease related dental research in Brazil presented at the 38th Annual Meeting of the Brazilian Division of the International Association for Dental Research (SBPqO). A search was carried out in the proceedings of the meeting to retrieve all abstracts. Those containing the term "COVID-19" in titles, abstracts, or keywords, and/or those of which the scope approached a COVID-19-related topic were included. The variables extracted from abstracts were: presenter category, field of study, design, data collection method, population, affiliation, and authors' gender. Descriptive and inferential statistics were used, with a significance level of α = 0.05. The search retrieved 185 abstracts, 5 did not meet study eligibility criteria and were excluded. COVID-19-related research was presented by either aspiring/associate members (67.8%) or beginner members (32.2%). Data collection methods were predominantly digitally mediated (65%), followed by secondary data use (25%), and in-person data collection (7.2%). Irrespective of the role of authorship, there were a ratio of two female authors to each male. Among the last authors, the ratio was three females to each male. Female lead authors more frequently came from the Southeast region (71.8%; p = 0.470). There was an association between presenter category and study design (p = 0.012), clinical and epidemiological studies were more concentrated among experienced presenters. In conclusion, female dental researchers affiliated to southeastern institutions approached the topic of pandemic more frequently than male colleagues. The use of digital technology for data collection may have long-lasting impacts on the teaching and publication of dental research.

Exploring children's dental pain experiences helps to develop healthcare policies for improving oral health and quality of life. A cross-sectional study involved 300 parents/caregivers of four- to seven-year-old children using snowball sampling. Parents/caregivers self-completed an online questionnaire on sociodemographic characteristics, parenting styles, their child's oral hygiene practices, free sugar consumption, and dental history. The questionnaire was created using Google Forms and was disseminated to parents/caregivers via E-mail and/or WhatsApp©. Descriptive and Poisson regression analyses were performed ( p < 0.05). Children's dental pain experience was reported by 20.3% of the parents. The authoritative parenting style was predominant. The child's mean age at the first consumption of sugar was 1.38 (±0.64) years, and 40.3% of the children had high-free sugar consumption. The mean age for the first dental appointment was 2.26 (±1.31) years, and 24.3% of the children never went to a dental appointment. The prevalence of dental pain experience was higher in children who attended their first dental appointment later (PR: 1.02; CI 95%: 1.01-1.03) and among those with high-free sugar consumption (PR: 1.90; CI 95%: 1.21-3.00). High sugar consumption and delay in the first dental appointment may increase the likelihood that children will experience dental pain.

Objective: To create and validate criteria for prioritizing problems related to policies and management of the health workforce., Methods: This methodological study was divided into three stages. First, the criteria were elaborated by means of a systematized literature review. Second, the criteria were evaluated online by a committee of judges comprised of eight specialists. In the third stage, an evaluation was carried out by the target audience in a hybrid workshop. The participants evaluated the material using the Suitability Assessment of Materials instrument, adapted for the research., Results: Three prioritization criteria (relevance, window of opportunity and acceptability) and a scoring scale were developed based on the literature review. In the evaluation by the committee of judges, the approval percentage of the criteria and prioritization method was 84%. Modifications were made based on suggestions in relation to the material presented to the specialists. In the pre-test stage, the approval percentage varied by item, with six of them reaching a maximum approval of 100% (corresponding to approximately 46% of the items), four reaching 92% and three achieving 83% each, indicating positive results., Conclusions: The developed criteria were considered valid for use in the context of policies and management in the area of human resources for health., Competing Interests: Conflicts of interest. None declared.

International differences in the incidence of many cancer types indicate the existence of carcinogen exposures that have not yet been identified by conventional epidemiology make a substantial contribution to cancer burden 1 . In clear cell renal cell carcinoma, obesity, hypertension and tobacco smoking are risk factors, but they do not explain the geographical variation in its incidence 2 . Underlying causes can be inferred by sequencing the genomes of cancers from populations with different incidence rates and detecting differences in patterns of somatic mutations. Here we sequenced 962 clear cell renal cell carcinomas from 11 countries with varying incidence. The somatic mutation profiles differed between countries. In Romania, Serbia and Thailand, mutational signatures characteristic of aristolochic acid compounds were present in most cases, but these were rare elsewhere. In Japan, a mutational signature of unknown cause was found in more than 70% of cases but in less than 2% elsewhere. A further mutational signature of unknown cause was ubiquitous but exhibited higher mutation loads in countries with higher incidence rates of kidney cancer. Known signatures of tobacco smoking correlated with tobacco consumption, but no signature was associated with obesity or hypertension, suggesting that non-mutagenic mechanisms of action underlie these risk factors. The results of this study indicate the existence of multiple, geographically variable, mutagenic exposures that potentially affect tens of millions of people and illustrate the opportunities for new insights into cancer causation through large-scale global cancer genomics., (© 2024.

Background: Heart failure (HF), a common cause of hospitalization, is associated with poor short-term clinical outcomes. Little is known about the long-term prognoses of patients with HF in Latin America., Methods: BREATHE was the first nationwide prospective observational study in Brazil that included patients hospitalized due to acute heart failure (HF). Patients were included during 2 time periods: February 2011-December 2012 and June 2016-July 2018 In-hospital management, 12-month clinical outcomes and adherence to evidence-based therapies were evaluated., Results: A total of 3013 patients were enrolled at 71 centers in Brazil. At hospital admission, 83.8% had clear signs of pulmonary congestion. The main cause of decompensation was poor adherence to HF medications (27.8%). Among patients with reduced ejection fraction, concomitant use of beta-blockers, renin-angiotensin-aldosterone inhibitors and spironolactone decreased from 44.5% at hospital discharge to 35.2% at 3 months. The cumulative incidence of mortality at 12 months was 27.7%, with 24.3% readmission at 90 days and 44.4% at 12 months., Conclusions: In this large national prospective registry of patients hospitalized with acute HF, rates of mortality and readmission were higher than those reported globally. Poor adherence to evidence-based therapies was common at hospital discharge and at 12 months of follow-up., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Advanced urothelial bladder cancer (UBC) patients are tagged by a dismal prognosis and high mortality rates, mostly due to their poor response to standard-of-care platinum-based therapy. Mediators of chemoresistance are not fully elucidated. This work aimed to study the metabolic profile of advanced UBC, in the context of cisplatin resistance. Three isogenic pairs of parental cell lines (T24, HT1376 and KU1919) and the matching cisplatin-resistant (R) sublines were used. A set of functional assays was used to perform a metabolic screening on the cells. In comparison to the parental sublines, a tendency was observed towards an exacerbated glycolytic metabolism in the cisplatin-resistant T24 and HT1376 cells; this glycolytic phenotype was particularly evident for the HT1376/HT1376R pair, for which the cisplatin resistance ratio was higher. HT1376R cells showed decreased basal respiration and oxygen consumption associated with ATP production; in accordance, the extracellular acidification rate was also higher in the resistant subline. Glycolytic rate assay confirmed that these cells presented higher basal glycolysis, with an increase in proton efflux. While the results of real-time metabolomics seem to substantiate the manifestation of the Warburg phenotype in HT1376R cells, a shift towards distinct metabolic pathways involving lactate uptake, lipid biosynthesis and glutamate metabolism occurred with time. On the other hand, KU1919R cells seem to engage in a metabolic rewiring, recovering their preference for oxidative phosphorylation. In conclusion, cisplatin-resistant UBC cells seem to display deep metabolic alterations surpassing the Warburg effect, which likely depend on the molecular signature of each cell line.

Background: Oral outcomes may have an impact on quality of life. The aim of this study was to assess factors associated with the impact of fixed appliance orthodontic treatment on the oral health-related quality of life (OHRQoL) of adolescents., Material and Methods: Individuals aged 10 to 18 years undergoing orthodontic treatment were included. Data regarding adolescents' sex and age, parental schooling, family income, and number of individuals who depend on income were collected. Clinical variables, orthodontic tooth extraction and malocclusion severity were also analyzed. OHRQoL was assessed with a questionnaire with items distributed across nine domains: aesthetics, functional limitation, diet, hygiene, maintenance, physical impact, social impact, time constraints, and transport/cost inconveniences. The higher the score, the more negative the adolescent's perception of his/her OHRQoL. Statistical analysis was performed., Results: Seventy-five adolescents participated. Individuals aged ≤12 years had a more negative perception of the diet domain ( p =0.026). Individuals whose parents/guardians had ≥8 years of schooling had a more negative perception of the impact on the hygiene domain ( p <0.024). Individuals whose families had an income of ≤2 salaries had a more negative perception of the maintenance domain ( p =0.016). Girls had a more negative perception of the physical impact domain ( p <0.018). Girls ( p =0.011), adolescents whose families had an income of ≤2 salaries ( p =0.003), and adolescents who had severe malocclusion ( p =0.026) had a more negative perception of the transport/cost inconveniences domain. Girls had a significantly higher overall score in response to the questionnaire than boys ( p =0.041)., Conclusions: Adolescents' sex, age, and malocclusion as well as parental education and family income were associated with the impact of orthodontic treatment on adolescents' OHRQoL. Key words: Adolescent, Quality of life, Orthodontic treatment, Fixed appliance., Competing Interests: Conflicts of interest The authors have no potential conflicts of interest to declare., (Copyright: © 2024 Medicina Oral S.L.)

Background: Women, in comparison to men, experience worse outcomes after acute coronary syndrome (ACS). However, whether the female sex per se is an independent predictor of such adverse events remains unclear., Objective: This study aims to assess the association between the female sex and in-hospital mortality after ST-elevation myocardial infarction (STEMI)., Methods: We conducted a retrospective cohort study by enrolling consecutive STEMI patients admitted to a tertiary hospital from January 2018 to February 2019. All patients were treated per current guideline recommendations. Multivariable logistic regression models were applied to evaluate in-hospital mortality using GRACE variables. Model accuracy was evaluated using c-index. A p-value < 0.05 was statistically significant., Results: Out of the 1678 ACS patients, 709 presented with STEMI. The population consisted of 36% women, and the median age was 61 years. Women were older (63.13 years vs. 60.53 years, p = 0.011); more often presented with hypertension (75.1% vs. 62.4%, p = 0.001), diabetes (42.2% vs. 27.8%, p < 0.001), and hyperlipidemia (34.1% vs. 23.9%, p = 0.004); and were less likely to undergo percutaneous coronary intervention (PCI) via radial access (23.7% vs. 46.1%, p < 0.001). In-hospital mortality rate was significantly higher in women (13.2% vs. 5.6%, p = 0.001), and the female sex remained at higher risk for in-hospital mortality (OR 2.79, 95% CI 1.15-6.76, p = 0.023). A multivariate model including age, sex, systolic blood pressure, cardiac arrest, and Killip class was 94.1% accurate in predicting in-hospital mortality, and the c-index was 0.85 (95% CI 0.77-0.93)., Conclusion: After adjusting for the risk factors in the GRACE prediction model, women remain at higher risk for in-hospital mortality.

The present study aimed to investigate associations between the self-perceived dental treatment need and clinical factors, familial characteristics, and school context in adolescents. A cross-sectional study was conducted with a representative sample of 746 students aged 15 to 19 years in a medium-sized city in Brazil. Data collection involved the use of a sociodemographic questionnaire, an oral health questionnaire, and the Family Adaptability and Cohesion Scales (FACES III) instrument. Clinical examinations were performed by two trained and calibrated examiners (Kappa > 0.80) using the Nyvad criteria. A robust logistic regression analysis for complex samples was performed using a multilevel approach (α = 5%). The individual factors associated with the self-perceived treatment need were dental pain (OR = 1.08; 95% CI: 1.01-1.16), the loss of the first molars (OR = 1.09; 95% CI: 1.03-1.15), and disengaged family cohesion (OR = 1.15; 95% CI: 1.01-1.31). In terms of context, attending a public school was associated with the self-perceived treatment need (OR = 1.17; 95% CI: 1.02-1.33). Thus, the individual factors of toothache, tooth loss, and a disengaged family, as well as the school context, exerted an influence on the self-perceived treatment need.

Purpose: To investigate the effects of auditory training with synthesized voices on intra- and inter-rater agreement of the auditory-perceptual voice analysis of roughness and breathiness., Methods: This was an experimental study consisting of four auditory training sessions. The sample consisted of twenty raters, students from a Speech-Language Pathology course, who had previous experience with auditory-perceptual assessment. The raters participated in the four training sessions with a seven-day break in between sessions. Each training consisted of three tasks: 1) Pre-training activity: Participants were asked to rate 20 natural voices, normal and dysphonic, from zero to three, according to the parameters of roughness and breathiness; 2) Training activity: Synthesized voice anchor stimuli were presented, and participants were asked to rate them from zero to three. Four stimuli were related to roughness and four to breathiness. Participants heard 20 voice stimuli and were instructed to pair the natural voice with the synthesized anchor stimulus that most resembled it; and 3) Post-training activity: the 20 voices from the pre-training activity were randomized and participants rated the same voices, without prior knowledge that these were repeated. Statistical analysis of data was performed using the AC 2 test, to assess the extent of agreement between raters, and the Friedman test to compare the training sessions. A 5% significance level was considered., Results: For the auditory-perceptual voice analysis of roughness, intra-rater agreement results ranged from 79% to 86% between the first and fourth auditory training session, with improvement in intra-rater agreement from the fourth session forward (P = 0.005). For the analysis of breathiness, results ranged from 88% to 92% between the first and fourth auditory training sessions, with improvement from the fourth session forward (P = 0.036). Inter-rater agreement results for the auditory-perceptual analysis of roughness ranged from 23% to 34%, and from 48% to 61% for breathiness, with no differences regarding training (P = 0.855)., Conclusion: The auditory-perceptual breathiness parameter had a higher AC 2 indicator compared to the roughness parameter, suggesting better agreement. The intra-rater agreement showed improvement starting from the fourth auditory training session for the assessment of roughness and breathiness. The auditory training program did not show a positive inter-rater agreement impact., (Copyright © 2021 The Voice Foundation. Published by Elsevier Inc. All rights reserved.)

Objective: To evaluate the presence of sleep disorders, obesity and anxiety associated with cavitated carious lesions in children aged 8 to 10 years., Materials and Methods: A cross-sectional study was carried out in the Northeast of Brazil. The sample was comprised of 793 schoolchildren randomly selected from public and private schools. Calibrated examiners (Kappa >0.80) performed the clinical examination of dental caries using the International Caries Detection and Assessment System and applied the Revised Children's Manifest Anxiety Scale and the Sleep Disturbance Scale for Children questionnaires. The anthropometric variables evaluated were weight and height. Negative binomial regressions (α ≤ 0.05) were performed. A Directed Acyclic Graph was prepared using DAGitty software (version 3.0), to select the co-variables for the statistical fits., Results: The prevalence of tooth decay was 52.8%. The mean number of tooth surfaces with cavitated caries was 2.2(2.8), 58.9% of the schoolchildren had some type of sleep disorder, while 20.2% were anxious and 29.1% were obese. Sleep disturbance (RR = 1.38; 95% CI: 1.05-1.83), general anxiety (RR = 1.71; 95% CI: 1.32-2.21), obesity (RR = 1.48; 95% CI: 1.17-1.86) were associated with dental caries in the final model., Conclusion: The presence of carious lesions was higher in children with sleep disorders, anxiety, obesity, and those who experienced dry mouth., (© 2024 American Association of Public Health Dentistry.)

Aim: To compare oral health indicators of children/adolescents with Down syndrome (DS) with a group of children/adolescents without DS., Methods and Results: This cross-sectional study included 144 individuals with DS, ages 4 to 18 years, matched for age and sex with a group of 144 individuals without DS, and their parents/caregivers. Parents/caregivers completed a questionnaire regarding sociodemographic information and habits related to their children's oral health. Clinical examination of the children/adolescents evaluated dental caries experience (DMFT/dmft), bleeding on periodontal probing, presence of visible plaque, clinical consequences of untreated dental caries (PUFA/pufa), and malocclusion (DAI). The chi-square test, linear by linear test, and Mann-Whitney test were used to compare the variables between the groups (p < .05). Children/adolescents without DS brushed their teeth more times per day (p < .001) and had a higher frequency of daily sugar intake (p < .001). The children/adolescents in the DS group had a greater presence of gingival bleeding (p < .001) and had a greater number of cases of "severe malocclusion" and "very severe malocclusion" (p = .001). No difference was found in the prevalence of dental caries between the two groups., Conclusion: The children/adolescents in the DS group had a greater presence of gingival bleeding during the clinical examination and had a greater need for orthodontic treatment., (© 2023 Special Care Dentistry Association and Wiley Periodicals LLC.)

Ultrafine particles (UFP, those with diameters ≤ 100 nm), have been reported to potentially penetrate deeply into the respiratory system, translocate through the alveoli, and affect various organs, potentially correlating with increased mortality. The aim of this study is to assess long-term trends (5-11 years) in mostly urban UFP concentrations based on measurements of particle number size distributions (PNSD). Additionally, concentrations of other pollutants and meteorological variables were evaluated to support the interpretations. PNSD datasets from 12 urban background (UB), 5 traffic (TR), 3 suburban background (SUB) and 1 regional background (RB) sites in 15 European cities and 1 in the USA were evaluated. The non-parametric Theil-Sen's method was used to detect monotonic trends. Meta-analyses were carried out to assess the overall trends and those for different environments. The results showed significant decreases in NO, NO 2 , BC, CO, and particle concentrations in the Aitken (25-100 nm) and the Accumulation (100-800 nm) modes, suggesting a positive impact of the implementation of EURO 5/V and 6/VI vehicle standards on European air quality. The growing use of Diesel Particle Filters (DPFs) might also have clearly reduced exhaust emissions of BC, PM, and the Aitken and Accumulation mode particles. However, as reported by prior studies, there remains an issue of poor control of Nucleation mode particles (smaller than 25 nm), which are not fully reduced with current DPFs, without emission controls for semi-volatile organic compounds, and might have different origins than road traffic. Thus, contrasting trends for Nucleation mode particles were obtained across the cities studied. This mode also affected the UFP and total PNC trends because of the high proportion of Nucleation mode particles in both concentration ranges. It was also found that the urban temperature increasing trends might have also influenced those of PNC, Nucleation and Aitken modes., 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 © 2024 The Authors.

Aim: The aim of this randomized clinical trial was to compare the impact of two management options for primary molars with pulp necrosis (pulpectomy or extraction) on children's oral health-related quality of life (OHRQoL)., Design: A total of 100 children aged 3-5 years with at least one necrotic primary molar were selected and randomized into the study groups. The Brazilian version of early childhood oral health impact scale (B-ECOHIS) was completed by the parent proxy reports at baseline and after 4, 8 and 12 months. Differences between the trial groups were assessed through bootstrap linear regression for B-ECOHIS scores, logistic regression for dental pain self-reports and anxiety scores (α = 5%)., Results: The mean (SD) B-ECOHIS scores at baseline and after 12 months were 17.7 (6.5) and 3.0 (4.0) in the pulpectomy group and 18.8 (7.7) and 7.9 (7.7) in the extraction group. Both treatments significantly improved OHRQoL, but tooth extraction group showed higher scores in total B-ECOHIS (p < .001) and most domains, indicating lower OHRQoL. Furthermore, higher anxiety levels were reported for dental extraction compared to pulpectomy (OR = 2.52; p = .008)., Conclusion: Pulpectomy resulted in an improved OHRQoL scores after 12 months when compared to tooth extraction and should be considered as the treatment of choice for necrotic primary molars., (© 2023 The Authors.

This is a protocol for an overview to summarize the findings of Systematic Reviews (SR) dealing with Photodynamic Inactivation (PDI) for control of oral diseases. Specific variables of oral infectious will be considered as outcomes, according to dental specialty. Cochrane Database of Systematic Reviews (CDSR), MEDLINE, LILACS, Embase, and Epistemonikos will be searched, as well as reference lists. A search strategy was developed for each database using only terms related to the intervention (PDI) aiming to maximize sensitivity. After checking for duplicate entries, selection of reviews will be performed in a two-stage technique: two authors will independently screening titles and abstracts, and then full texts will be assessed for inclusion/exclusion criteria. Any disagreement will be resolved through discussion and/or consultation with a third reviewer. Data will be extracted following the recommendations in Chapter V of Cochrane Handbook and using an electronic pre-specified form. The evaluation of the methodological quality and risk of bias (RoB) of the SR included will be carried out using the AMSTAR 2 and ROBIS. Narrative summaries of relevant results from the individual SR will be carried out and displayed in tables and figures. A specific summary will focus on PDI parameters and study designs, such as the type and concentration of photosensitizer, pre-irradiation time, irradiation dosimetry, and infection or microbiological models, to identify the PDI protocols with clinical potential. We will summarize the quantitative results of the SRs narratively., (© 2024. The Author(s), under exclusive licence to European Photochemistry Association, European Society for Photobiology.)

Studies involving the immune response in Chagas disease suggest an imbalance in the immune response of symptomatic patients, with an inflammatory profile dominating in Chagas heart disease, mainly by tumour necrosis factor (TNF). TNF is considered a key cytokine in immunopathology in chronic carriers in several processes during the immune response. Our work aimed to evaluate regulatory (interleukin [IL]-4 and IL-10) and inflammatory (TNF, interferon-gamma [IFN-γ], IL-2 and IL-6) cytokines in peripheral blood mononuclear cells culture supernatants. of affected patients with undetermined clinical forms-IND (n = 13) mild heart form-CARD1 (n = 13) and severe cardiac form-CARD2 (n = 16), treated in vitro with two TNF blockers, Adalimumab (ADA) and Etanercept (ETA) alone or in association with Benznidazole (BZ). The results indicate that ADA was more competent in blocking TNF (compared to ETA) in all groups but with much lower levels in the CARD2 group. ETA statistically decreased TNF levels only in the CARD2 group. IFN-γ increased in the CARD2 group after treatment with ETA relative to ADA. IL-4 had its levels decreased when treated by both drugs. IL-2 was detected in cells from CARD2 carriers compared to the NEG group after treatment with both drugs. The association with BZ decreased levels of IL-2/TNF and increased IL-4. These data reinforce the participation of TNF in severe Chagas heart disease and bring perspectives on using these blockers in the immunological treatment of Chagas disease since the use of BZ is extremely limited in these patients., (© 2024 John Wiley & Sons Ltd.)

Importance: Readmissions after an index heart failure (HF) hospitalization are a major contemporary health care problem., Objective: To evaluate the feasibility and efficacy of an intensive telemonitoring strategy in the vulnerable period after an HF hospitalization., Design, Setting, and Participants: This randomized clinical trial was conducted in 30 HF clinics in Brazil. Patients with left ventricular ejection fraction less than 40% and access to mobile phones were enrolled up to 30 days after an HF admission. Data were collected from July 2019 to July 2022., Intervention: Participants were randomly assigned to a telemonitoring strategy or standard care. The telemonitoring group received 4 daily short message service text messages to optimize self-care, active engagement, and early intervention. Red flags based on feedback messages triggered automatic diuretic adjustment and/or a telephone call from the health care team., Main Outcomes and Measures: The primary end point was change in N-terminal pro-brain natriuretic peptide (NT-proBNP) from baseline to 180 days. A hierarchical win-ratio analysis incorporating blindly adjudicated clinical events (cardiovascular deaths and HF hospitalization) and variation in NT-proBNP was also performed., Results: Of 699 included patients, 460 (65.8%) were male, and the mean (SD) age was 61.2 (14.5) years. A total of 352 patients were randomly assigned to the telemonitoring strategy and 347 to standard care. Satisfaction with the telemonitoring strategy was excellent (net promoting score at 180 days, 78.5). HF self-care increased significantly in the telemonitoring group compared with the standard care group (score difference at 30 days, -2.21; 95% CI, -3.67 to -0.74; P = .001; score difference at 180 days, -2.08; 95% CI, -3.59 to -0.57; P = .004). Variation of NT-proBNP was similar in the telemonitoring group compared with the standard care group (telemonitoring: baseline, 2593 pg/mL; 95% CI, 2314-2923; 180 days, 1313 pg/mL; 95% CI, 1117-1543; standard care: baseline, 2396 pg/mL; 95% CI, 2122-2721; 180 days, 1319 pg/mL; 95% CI, 1114-1564; ratio of change, 0.92; 95% CI, 0.77-1.11; P = .39). Hierarchical analysis of the composite outcome demonstrated a similar number of wins in both groups (telemonitoring, 49 883 of 122 144 comparisons [40.8%]; standard care, 48 034 of 122 144 comparisons [39.3%]; win ratio, 1.04; 95% CI, 0.86-1.26)., Conclusions and Relevance: An intensive telemonitoring strategy applied in the vulnerable period after an HF admission was feasible, well-accepted, and increased scores of HF self-care but did not translate to reductions in NT-proBNP levels nor improvement in a composite hierarchical clinical outcome., Trial Registration: ClinicalTrials.gov Identifier: NCT04062461.
