Prevalence analysis of Chagas disease by age group in an endemic region of Brazil: possible scenario of active vectorial transmission.

Objectives: Chagas disease (CD) is an infectious disease that predominantly affects poor and vulnerable populations. The last estimate conducted by the World Health Organization in Latin America regarding the prevalence of CD occurred more than 10 years ago. However, there is a scarcity of data assessing the magnitude of CD in populations residing in considered high-risk regions. Therefore, this study aimed to assess the seroprevalence of CD in an endemic region in Northern Minas Gerais through serologic screening. Methods: This is a prevalence study conducted in the municipalities of Catuti, Mato Verde, Mirabela, Montes Azul, and São Francisco, Minas Gerais, Brazil. Data collection occurred between December 2021 and December 2022, involving a questionnaire with closed-ended questions. The variables analyzed included serologic test results, stratified age groups, health indicators, and housing conditions. Results: Of the 2978 participants, 272 individuals (9.1%) tested positive for CD serology. In the age group of 4 to 14 years, 15 to 49 years, and 50 years or older, the prevalence of positive serology was 0.8% (95% confidence interval [CI] 0.16-1.43), 5.5% (95% CI 4.20-6.83), and 18.8% (95% CI 16.48-21.11), respectively. Among the participating municipalities, Mato Verde had the highest prevalence of positive serology for CD (17%). For participants aged 4 to 14 years with positive serology for CD, first-degree relatives were invited to undergo serologic testing. It was possible to collect samples from relatives of all participants in this age group. However, none of the relatives tested positive. Conclusion: This study identified a 9.1% prevalence of individuals affected by CD who were unaware of their condition. In addition, having infected children in the 4 to 14 age group with mothers with negative serology would rule out congenital transmission of the disease.

Diathermy Versus Scalpel in Midline Abdominal Incision: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

INTRODUCTION: Our study aimed to compare the midline abdominal incision with scalpel and diathermy. METHODS: PubMed, EMBASE, and Cochrane were searched through January 2024 following PRISMA guidelines (PROSPERO, ID: CRD42024516771), and only randomized controlled trials were included. Heterogeneity was assessed using Cochran's Q test and the I2 heterogeneity index. Statistical analysis was performed using Review Manager 5.4 software. RESULTS: Six randomized controlled trials were included, from which 469 patients (51.5%) received diathermy incision and 442 patients (48.5%) underwent the scalpel technique. Patients treated with the electrocautery approach had less incision blood loss (MD -17.57 mL; P < .01). No statistically significant differences were found between groups regarding wound infection incidence, incision time, incision area or first-day postoperative pain. CONCLUSION: Diathermy use in midline abdominal incision may be advocated as it demonstrated a significant reduction in incision-related blood loss, with no differences in wound infection or early postoperative pain incidences compared to the scalpel.

Safety and efficacy of biologic drugs in children or adolescents with atopic dermatitis: A systematic review and meta-analysis of randomized controlled trials.

Children and adolescents suffering from moderate-to-severe atopic dermatitis (AD) face a significant disease burden that greatly impacts their quality of life. Treatment options for AD are currently limited. To assess the safety and efficacy of biologic drugs, dupilumab, lebrikizumab, or tralokinumab, in improving outcomes in patients with moderate to severe inadequately controlled AD. We searched PubMed, Embase and Cochrane databases for randomized controlled trials (RCTs) comparing dupilumab, lebrikizumab or tralokinumab to placebo in patients with AD. We computed odds ratios (ORs) for binary endpoints, with 95% confidence intervals (CIs), random effects model was used and a p-value <0.05 was considered as statistically significant. We analysed data into Review Manager 5.4. A total of five RCTs and 973 patients were included, of whom 592 were prescribed a biologic drug. Compared with placebo, patients receiving a biologic drug had a greater improvement, achieved an Investigator Global Assessment (IGA) score of 0 or 1 (OR 5.05; 95% CI 3.08-8.29), Eczema Area and Severity Index (EASI) 75 (OR 6.87; 95% CI 4.71-10.02), EASI 50 (OR 8.89; 95% CI 6.18-12.78) and EASI 90 (8.30; 95% CI 4.81-14.31). The proportion of patients with 3 points or more (OR 6.56; 95% CI 4.34-9.90) or 4 points or more (OR 8.09; 95% CI 5.19-12.59) improvement from baseline in peak pruritus NRS was significantly higher with biologic drugs than placebo. There were no significant differences between groups regarding adverse events (OR 0.79; 95% CI 0.58-1.07), and conjunctivitis (OR 2.08; 95% CI 1.00-4.33). In this meta-analysis, dupilumab, lebrikizumab, and tralokinumab have shown significant improvements in signs, symptoms and quality of life in children or adolescents with moderate to severe AD. Larger studies may be needed to continue evaluating the safety and efficacy of these biologic drugs in this patient population.

Association between positive serology for COVID-19 and chagas cardiomyopathy progression: The SaMi-Trop project.

BACKGROUND: Chagas Disease (CD) can cause Chagas cardiomyopathy. The new coronavirus disease (COVID-19) also affects the cardiovascular system and may worsen Chagas cardiomyopathy. However, the cardiac evolution of patients with CD infected by COVID-19 is not known. Thus, the objective of this study is to assess, within one year, whether there was cardiac progression after COVID-19 in CD. METHODS: Longitudinal study with CD patients. The outcome was cardiac progression, defined as the appearance of new major changes in the current ECG compared to the previous ECG considered from the comparison of electrocardiograms (ECGs) performed with an interval of one year. Positive Anti-SARS-CoV2 Serology was the independent variable of interest. For each analysis, a final multiple model was constructed, adjusted for sociodemographic, clinical, and pandemic-related characteristics. RESULTS: Of the 404 individuals included, 22.8 % had positive serology for COVID-19 and 10.9 % had cardiac progression. In the final model, positive serology for COVID-19 was the only factor associated with cardiac progression in the group as a whole (OR = 2.65; 95 % CI = 1.27-5.53) and for new-onset cardiomyopathy in the group with normal previous ECG (OR = 3.50; 95 % CI = 1.21-10.13). CONCLUSION: Our study shows an association between COVID-19 and progression of Chagas cardiomyopathy, evaluated by repeated ECGs, suggesting that COVID-19 accelerated the natural history of CD.

General anesthesia versus conscious sedation in mechanical thrombectomy for patients with acute ischemic stroke: systematic review and meta-analysis.

BACKGROUND: After recently published randomized clinical trials, the choice of the best anesthetic procedure for mechanical thrombectomy (MT) in acute ischemic stroke (AIS) due to large vessel occlusion (LVO) is not definite. OBJECTIVE: To compare the efficacy and safety of general anesthesia (GA) versus conscious sedation (CS) in patients with AIS who underwent MT, explicitly focusing on procedural and clinical outcomes and the incidence of adverse events. METHODS: PubMed, Embase, and Cochrane were systematically searched for randomized controlled trials (RCTs) comparing GA versus CS in patients who underwent MT due to LVO-AIS. Odds ratios (ORs) were calculated for binary outcomes, with 95% confidence intervals (CIs). Random effects models were used for all outcomes. Heterogeneity was assessed with I2 statistics. RESULTS: Eight RCTs (1,300 patients) were included, of whom 650 (50%) underwent GA. Recanalization success was significantly higher in the GA group (OR 1.68; 95% CI 1.26-2.24; p < 0.04) than in CS. No significant difference between groups were found for good functional recovery (OR 1.13; IC 95% 0.76-1.67; p = 0.56), incidence of pneumonia (OR 1.23; IC 95% 0.56- 2,69; p = 0.61), three-month mortality (OR 0.99; IC 95% 0.73-1.34; p = 0.95), or cerebral hemorrhage (OR 0.97; IC 95% 0.68-1.38; p = 0.88). CONCLUSION: Despite the increase in recanalization success rates in the GA group, GA and CS show similar rates of good functional recovery, three-month mortality, incidence of pneumonia, and cerebral hemorrhage in patients undergoing MT.

ANTECEDENTES: A trombectomia mecânica (TM) é o padrão de tratamento para pacientes com acidente vascular cerebral isquêmico agudo (AVCI) devido à oclusão de grandes vasos (OGV). No entanto, ainda não está claro qual é o procedimento anestésico mais benéfico para a TM. OBJETIVO: Nosso objetivo foi comparar a eficácia e a segurança da anestesia geral (AG) versus sedação consciente (SC) em pacientes com AVCI submetidos à TM, focando especificamente nos resultados procedimentais e clínicos, bem como na incidência de eventos adversos. MéTODOS: Foram realizadas buscas sistemáticas nas bases PubMed, Embase e Cochrane por ensaios clínicos randomizados (ECRs) comparando AG versus SC em pacientes submetidos à TM devido a AVCI por OGV. Razões de chances (ORs) foram calculadas para desfechos binários, com intervalos de confiança de 95% (ICs). Modelos de efeitos aleatórios foram usados para todos os resultados. A heterogeneidade foi avaliada com estatísticas I2. RESULTADOS: Oito ensaios clínicos randomizados (1.300 pacientes) foram incluídos, dos quais 650 (50%) foram submetidos à AG. O sucesso da recanalização foi significativamente maior no grupo AG (OR 1,68; IC 95% 1,26­2,24; p < 0,04) em comparação com SC. No entanto, não houve diferença significativa entre os grupos para recuperação funcional adequada (OR 1,13; IC 95% 0,76­1,67; p = 0,56), incidência de pneumonia (OR 1,23; IC 95% 0,56- 2,69; p = 0,61), mortalidade em três meses (OR 0,99; IC 95% 0,73- 1,34; p = 0,95) ou hemorragia cerebral (OR 0,97; IC 95% 0,68- 1,38; p = 0,88). CONCLUSãO: Apesar do aumento significativo nas taxas de sucesso de recanalização no grupo AG, AG e SC mostram taxas semelhantes de recuperação funcional, mortalidade, pneumonia e hemorragia em pacientes com AVCI submetidos à TM.

Comparison of refractive surgeries (SMILE, LASIK, and PRK) with and without corneal crosslinking: systematic review and meta-analysis.

Corneal crosslinking (CXL) is used for treating keratoconus and post-laser in situ keratomileusis ectasia. However, refractive surgery is not usually performed with prophylactic CXL. Therefore, we performed a meta-analysis comparing outcomes of refractive surgeries with vs without prophylactic CXL. We systematically searched databases for studies comparing refractive surgeries for myopic correction with vs without prophylactic corneal crosslinking. Review Manager 5.4.1 was used to perform statistical analysis. We included 2820 eyes from 28 studies. Compared with refractive surgery alone, surgery with prophylactic CXL resulted in decreased central corneal thickness, corrected distance visual acuity logMAR, and safety and efficacy indices. There were no significant differences in postoperative uncorrected distance visual acuity of 20/20 or better at ≥12 months and other visual outcomes among both groups. More randomized controlled trials with standard crosslinking protocols are needed to analyze the prophylactic use of crosslinking with refractive surgeries.

Effectiveness of group aerobic and/or resistance exercise programs associated with pelvic floor muscle training during prenatal care for the prevention and treatment of urinary incontinence: A systematic review.

AIM: To evaluate the effectiveness of aerobic and/or resistance group exercise programs associated with pelvic floor muscle training (PFMT) during prenatal care for the prevention and treatment of urinary incontinence (UI) using the best level of evidence. METHODS: A search was carried out in the MEDLINE/PubMed, LILACS, PEDro, CENTRAL, and SCOPUS databases, without restrictions. The terms "urinary incontinence" and "pregnant woman" were used. Randomized and quasi-randomized clinical trials were included using aerobic and/or resistance exercise programs plus PFMT as an intervention compared to usual care. The Cochrane tool (RoB 2.0) and GRADE were used to assess risk of bias and certainty of evidence, respectively. Quantitative analysis was assessed by meta-analyses. RESULTS: Five publications were included. There was a reduction in the reports of UI postintervention at 16 weeks (RR: 0.83; 95% CI: 0.74-0.93, one study, 762 women, random effects: p = 0.002) and after 3 months (RR: 0.76; 95% CI: 0.60-0.95, one study, 722 women, random effects: p = 0.02), based on moderate certainty of evidence and improvement in UI-specific quality of life (MD: -2.42; 95% CI: -3.32 to -1.52, one study, 151 women, random effects: p < 0.00001), based on low quality of evidence. Other results showed no difference between the postintervention groups, with low and very low evidence. CONCLUSION: There is moderate evidence that the aerobic and/or resistance exercise program associated with PFMT compared to usual care can reduce postintervention UI, as well as 3 months postintervention, and that it can improve UI-specific quality of life, but with low-evidence certainty.

Fluxo digital na odontologia através do escaneamento intraoral em próteses fixas: revisão integrativa / Digital flow in dentistry through intraoral scanning in fixed prosthesis: integrative review

As novas tecnologias utilizadas na Odontologia, como a digitalização de imagens, estão levando a mudanças significativas na obtenção de próteses e infraestruturas protéticas, de funcionamento de softwares. A grande área da engenharia desenvolve processos para fabricação de diversos produtos industrializados com auxílio da tecnologia CAD/CAM. O uso desta técnica vem sendo sugerido na clínica odontológica desde a década de setenta, com o objetivo de simplificar, automatizar e garantir níveis de qualidade com adaptações micrométricas das próteses dentárias. O processo pode envolver diferentes ambientes: industrial, laboratorial ou clínico. O objetivo do presente estudo é revisar de forma integrativa a utilização do escaneamento na Odontologia na área de Prótese Dentária, enfatizando os resultados do seu uso e as diferentes formas de escaneamento e comparando, quando possível, este sistema ao método convencional de moldagem. Notou-se que o escaneamento intraoral resulta em próteses fixas com funcionalidade clínica similar ou melhor do que a moldagem convencional, além de estar relacionada a um conforto aumentado por parte do paciente. Além disto, o escaneamento intraoral reduz o tempo de cadeira do paciente, além de estar associado ao fluxo digital laboratorial mais rápido, o que reduz também o tempo total de fabricação destas próteses, sendo ideal para uma melhor administração do tempo de consultório.

Olive oil and body fat: a systematic review with meta-analysis.

Diet composition has a great impact on body composition. Several studies have suggested a beneficial effect of adding olive oil to a calorie-restricted diet as a weight loss strategy. However, there is no clear direction regarding the effect of olive oil on body fat distribution. This systematic review with meta-analysis aims to investigate the effect of olive oil consumption (for cooking or as a supplement) on body fat distribution in adults. The present study was conducted following the recommendations of the Cochrane Handbook for Systematic Reviews of Interventions and was registered in the International Prospective Register of Systematic Reviews (PROSPERO CRD42021234652). All randomized clinical trials of parallel or crossover design found in PubMed (via MEDLINE), EMBASE, Web of Science and Scopus databases that compared the effects of olive oil with other oils on body fat distribution in adults were included. 52 articles were included. The results indicate that the consumption of olive oil does not seem to alter the distribution of body fat, despite a small indication that supplementation in capsules can increase adipose mass (Mean Difference = 0.28 kg, 95% CI [-0.27, 0.83]; between-groups difference p = 0.59) and waist circumference (mean difference = 1.74 kg, 95% CI [0.86, 1.62]; between-groups difference p < 0.01) and decrease its auxiliary culinary use (mean difference = -0.32 kg, 95% CI [-0.90, 0.26]). Lean mass responds negatively to OO the higher the dose (slope = -0.61, 95% CI [-1.01, -0.21], p = 0.003) and time offered (slope = -0.8822, 95% CI [-1.44, -0.33], p = 0.002). In conclusion, this systematic review showed that OO ingestion in different delivery vehicles, dosages, and durations can interfere body composition. It is important to emphasize that some other aspects of the population and the intervention, that were not possible to be explored in the analysis, could confound the real effects of OO on body composition.

Behavior changes in children/adolescents with attention deficit hyperactivity disorder during the COVID-19 pandemic: a systematic review / Mudanças comportamentais em crianças/adolescentes com transtorno de déficit de atenção e hiperatividade durante a pandemia de COVID-19: uma revisão sistemática

Abstract Objectives: to describe behavioral changes related to mental health in children and adolescents with Attention Deficit Hyperactivity Disorder during social isolation due to the COVID-19 pandemic. Methods: this is a systematic review conducted under the PRISMA protocol (2020) in the PubMed, SciELO and VHL databases, with a period of 2019-2022. Results: 3,735 studies were screened and ten were selected, according to the eligibility criteria. The sample had 4,688 participants. There was evidence of a worsening of signs and symptoms regarding the mental health of this population, expressed mainly through changes in mood, with increased anxiety, sadness or depressed symptoms, in addition to increased hyperactivity. Behavioral changes also included reduced sleep quality and physical activity, and increased use of digital technologies and screen time. Conclusions: it was described that children and youth groups, especially those with attention deficit hyperactivity disorder, had increased emotional symptoms and conduct problems when compared to before the pandemic, making it possible to recognize the negative repercussions of the changes imposed by it. These factors are important for planning more effective care strategies.

Esses fatores são importantes para o planejamento de estratégias de cuidado mais efetivas.

Algumas aprendizagens sobre o NASF: relato de uma experiência acadêmica

Esse relato de experiência aborda uma vivência que ocorreu no mês de agosto de 2019 em um Centro de Saúde da Comunidade de Palmas (CSC) ­ TO. O objeto da experiência é a atuação do NASF na oferta de saúde na puericultura (Projeto Bebê Clean), a qual tinha como objetivo intensificar a relação mãe e filho a respeito da amamentação, introdução alimentar e o shantala no CSC a partir da vivência em aulas práticas do Módulo Integração-Ensino-Serviço-Comunidade/IESC I do curso de Medicina do ITPAC Palmas. A metodologia aplicada consistiu na participação dos acadêmicos em uma oficina pedagógica no CSC com a equipe do NASF e a preceptora do módulo, visando conhecer a multidisciplinaridade e compreender as atividades realizadas por este, considerando o processo colaborativo e o papel do ACS como elo entre a equipe e a comunidade. A partir dessa vivência acadêmica foi possível reconhecer que a formação médica com aulas práticas na atenção primária à saúde possibilita a reflexão sobre o verdadeiro papel do médico, o qual vai além do ato de curar doenças e fazer cirurgias.

Caracterização dos sistemas de criação de caprinos e ovinos da Ilha de São Luís no estado do Maranhão, Brasil / Characterization of goat and sheep breeding systems at São Luis Island in the state of Maranhão, Brazil

Objetivou-se descrever o perfil dos sistemas de criação de caprinos e ovinos da Ilha de São Luís no estado do Maranhão. Para isso, realizou-se um estudo descritivo, exploratório e quali-quantitativo com 80 produtores rurais selecionados pela técnica Snowball, no período de fevereiro a abril de 2021. Em relação ao perfil do produtor rural, verificou-se predominância do gênero masculino (93,8%), apresentando faixa etária entre 25 a 60 anos (86,2%). A maioria dos produtores apresentavam ensino médio completo (23,8%) ou ensino superior completo (23,8%) e 88,8% dos produtores não estavam vinculados a organizações coletivas, associações, cooperativas ou sindicatos. Nas propriedades rurais o sistema de criação predominante era o semi-extensivo (73,8%) com presença de apriscos (76,2%) e as criações eram consorciadas com caprinos e ovinos (58,8%). A principal causa de morte nos animais verificada foi a verminose (58,8%). Conclui-se que se faz necessário o estabelecimento de medidas de estímulo às criações na Ilha de São Luís por meio de políticas públicas voltadas aos produtores locais, requerendo, sobretudo, assistência técnica, orientações zootécnicas, educação sanitária e acesso ao crédito, para, assim, deixar de ser apenas uma atividade de subsistência e passar a gerar maiores rendas para as famílias produtoras.

The objective of this research was to describe the profile of the goat and sheep rearing systems on the Island of São Luís in the state of Maranhão. For this, a descriptive, exploratory and qualitative-quantitative study was carried out with 80 rural producers selected by the Snowball technique, from February to April 2021. Regarding the profile of the rural producer, there was a predominance of males (93.8%), aging between 25 and 60 years (86.2%). Most producers had completed high school (23.8%) or higher education (23.8%) and 88.8% were not members of collective organizations, associations, cooperatives or unions. In rural properties, the predominant rearing system was semi-extensive (73.8%) with the presence of sheepfolds (76.2%) and mutual goats and sheep farming (58.8%). The main cause of death of animals was warm infections (58.8%). In conclusion, it is necessary to establish measures to support sheep and goat farming on the Island of São Luís through public policies focused on local producers, which require, above all, technical assistance, zootechnical guidelines, health education and access to credit in order to the farms stop being just a subsistence activity and start generating higher incomes for producing families.

Estigma da hanseníase por agentes comunitários de saúde: fatores associados / Stigma of leprosy by community health workers: associated factors

Objetivo: identificar os fatores associados ao estigma da hanseníase, manifestado na orientação quanto à separação de objetos no convívio familiar pelos agentes comunitários de saúde de Palmas, Tocantins, Brasil. Métodos: estudo transversal do tipo quantitativo realizado nas Unidades Básicas de Saúde de Palmas em uma população de 301 agentes comunitários de saúde, por meio de um questionário autoaplicável. Resultados: dos 301 agentes comunitários de saúde, 22,92% orientaram as pessoas no domicílio quanto à separação de objetos de uso pessoal, tais como talheres, copos, pratos, toalhas, roupa de cama, vestimentas e isolamento de dormitório. A orientação para separar objetos de uso pessoal foi significativamente maior para os agentes comunitários de saúde do sexo masculino (RP: 1,89; IC: 1,25-2,87), mais jovens (RP: 1,90; IC: 1,14-3,17), com menor tempo de moradia em Palmas (RP: 2,06; IC: 1,253,40), com localização da Unidade Básica de Saúde fora do plano diretor (RP: 1,75; IC: 1,11-2,76), que não fizeram curso em hanseníase (RP: 3,03; IC: 2,01-4,58), que nunca fizeram acompanhamento de casos (RP: 3,82; IC: 2,02-7,22) e que não teve um familiar acometido por hanseníase (RP: 1,96; IC: 1,10-3,47). Conclusão: a elevada prevalência de agentes comunitários de saúde que apresentam estigma da hanseníase representa uma barreira nas ações de controle da doença. Observou-se que as chances de ocorrência de estigma foram maiores nos agentes comunitários de saúde jovens, do sexo masculino, sem capacitação sobre hanseníase e com local de trabalho nas regiões periféricas do município. Fatores a serem considerados pelo programa de controle local com a adoção de Educação Permanente em Saúde. Investimentos em cursos direcionados à hanseníase podem contribuir para a redução do desconhecimento acerca da doença, pois os aspectos culturais e de crenças geracionais influenciam na manutenção de conceitos e do estigma social.

Objective: to identify the factors associated with the stigma of leprosy, manifested in guidance regarding the separation of objects in family life, by community health workers in Palmas, Tocantins, Brazil. Methods: quantitative cross-sectional study carried out in Basic Health Units in Palmas in a population of 301 community health workers, using a self-administered questionnaire. Results: of the 301 CHWs, 22.92% guided people at home regarding the separation of personal objects, such as cutlery, glasses, plates, towels, bed linen, clothing and bedroom isolation. Guidance to separate objects for personal use was significantly higher for male community health workers (PR: 1.89; CI:1.25-2.87), younger (PR:1.90; CI:1.14- 3.17), with less time living in Palmas (RP: 2.06; CI: 1.253.40), with the location of the Basic Health Units outside the master plan (PR: 1.75; CI: 1.11-2.76 ), who had not taken a leprosy course (PR:3.03; CI: 2.01-4.58), who had never followed up cases (PR:3.82; CI: 2.02-7.22) and who did not have a family member affected by leprosy (PR:1.96; CI: 1.10-3.47). Conclusion: the high prevalence of community health workers who have leprosy stigma represents a barrier in disease control actions. It was observed that the chances of stigma occurrence were higher in young, male community health agents, without training on leprosy and with a workplace in the peripheral regions of the city. Factors to be considered by the local control program with the adoption of Permanent Health Education. Investments in courses aimed at leprosy can contribute to reducing ignorance about the disease, as cultural aspects and generational beliefs influence the maintenance of concepts and social stigma.

Factors associated with bronchopulmonary aspiration: a national-based study / Factores asociados con la aspiración broncopulmonar: estudio de base nacional / Fatores associados à aspiração broncopulmonar: estudo de base nacional

ABSTRACT Objectives: to determine the prevalence of bronchopulmonary aspiration in the Brazilian scenario, the factors associated with the incident and the variables associated with death. Methods: a cross-sectional and analytical study, carried out from analysis of notifications of incidents related to bronchopulmonary aspiration of the Health Surveillance Notification System, from January 2014 to December 2018. Results: of the 264,590 notifications, 553 referred to aspiration, whose prevalence rate was 0.21%. There was an association between the event and age, ethnicity, main medical diagnosis, country region, service type, health unit and consequences for patients. Furthermore, four independent predictor variables for death were found: living in the North or South regions, being elderly and receiving healthcare at night. Conclusions: the prevalence rate of bronchopulmonary aspiration was small, but with a negative impact on patients.

RESUMEN Objetivos: determinar la prevalencia de broncoaspiración en el escenario brasileño, los factores asociados al incidente y las variables asociadas a la muerte. Métodos: estudio transversal y analítico, realizado a partir del análisis de notificaciones de incidentes relacionados con la aspiración broncopulmonar del Sistema de Notificación de Vigilancia Sanitaria, de enero de 2014 a diciembre de 2018. Resultados: de las 264.590 notificaciones, 553 se refirieron a aspiración, cuya tasa de prevalencia fue del 0,21%. Hubo asociación entre el evento y la edad, etnia, diagnóstico médico principal, región del país, tipo de servicio, unidad de salud y consecuencias para el paciente. Además, se encontraron cuatro variables predictoras independientes de muerte: vivir en la región Norte o Sur, ser anciano y recibir atención médica por la noche. Conclusiones: la tasa de prevalencia de aspiración broncopulmonar fue pequeña, pero con impacto negativo en los pacientes.

RESUMO Objetivos: determinar a prevalência de aspiração broncopulmonar no cenário brasileiro, os fatores associados ao incidente e as variáveis associadas ao óbito. Métodos: estudo transversal e analítico, realizado a partir da análise das notificações de incidentes relacionados à aspiração broncopulmonar do Sistema de Notificações em Vigilância Sanitária, no período de janeiro de 2014 a dezembro de 2018. Resultados: das 264.590 notificações, 553 se referiam à aspiração, cuja taxa de prevalência foi de 0,21%. Houve associação entre o evento e idade, etnia, diagnóstico médico principal, região do país, tipo de serviço, unidade de saúde e consequência para o paciente. Ainda, verificaram-se quatro variáveis preditoras independentes para o óbito: residir na Região Norte ou Sul, ser idoso e receber atendimento à saúde no período noturno. Conclusões: a taxa de prevalência de aspiração broncopulmonar foi pequena, mas com impacto negativo para os pacientes.

Inactivation of avian influenza viruses by hydrostatic pressure as a potential vaccine development approach.

Vaccines are a recommended strategy for controlling influenza A infections in humans and animals. Here, we describe the effects of hydrostatic pressure on the structure, morphology and functional characteristics of avian influenza A H3N8 virus. The effect of hydrostatic pressure for 3 h on H3N8 virus revealed that the particles were resistant to this condition, and the virus displayed only a discrete conformational change. We found that pressure of 3 kbar applied for 6 h was able to inhibit haemagglutination and infectivity while virus replication was no longer observed, suggesting that full virus inactivation occurred at this point. However, the neuraminidase activity was not affected at this approach suggesting the maintenance of neutralizing antibody epitopes in this key antigen. Our data bring important information for the area of structural virology of enveloped particles and support the idea of applying pressure-induced inactivation as a tool for vaccine production.

The Protagonism of the Brazilian Health Regulatory System in the Evolution of Patient Safety in the Country: History, Dilemmas, and Current Challenges.

OBJECTIVE: This article aims to identify and analyze the legal and regulatory frameworks with an interface with patient safety, considering the historical path of the patient safety policy in Brazil. METHODS: This is a historical review based on the relevant literature to the topic such as papers, legislation, and official documents with an interface with public health policies from 1988 to 2019. We also performed a documentary search to include data from the Brazilian Health Regulatory Agency (ANVISA) such as normative and nonnormative regulatory instruments. After organizing the data, the process of content analysis was performed. RESULTS: We debated initially the historical aspects of sanitary surveillance of health services in addition to main actions taken by the Brazilian Health Regulatory System, which includes sanitary regulation and patient safety challenges. We identified a diversity of regulations published by ANVISA in the past decade related to patient safety, in addiction to sanitary actions. These initiatives culminated in the establishment of the National Patient Safety Program in 2013, followed by other health improvements, such as surveillance, incidents monitoring, and safe practices self-assessment. CONCLUSIONS: The regulation and sanitary actions directed to patient safety in Brazil have increased after the creation of ANVISA. In the face of this activities, the social role played by the Brazilian Health Regulatory System toward the advancement in the field of risk minimization in health services can be highlighted as a protagonist in the process of promoting patient safety.

Identificação parasitológica da cama de frango reutilizada em uma granja avícola / Parasitological identification of chicken bed reused in a poultry farm

Objetivou-se avaliar a carga parasitária da cama de frango de uma granja avícola localizada no município de Paço do Lumiar - MA. Foram coletadas 50 amostras de cama de frango de 10 galpões. Essa cama já havia sido utilizada seis vezes nos lotes anteriores. Para as análises parasitológicas foram utilizados os métodos de Sedimentação Espontânea, Método de Sheather, Esporulação para diagnóstico de oocistos de coccídios. Foram identificados ovos de nematódeos dos gêneros Strongyloides (72%), Heterakis (18%) e Ascaridia (10%). As larvas as do gênero Strongyloides destacaram-se como as mais prevalentes, com frequência de 97% de casos, seguido geohelmintos (3%). Encontrou-se 1200 oocistos de Eimeria, no estágio de esporulação. Foram encontrados também ácaros e cascudinhos (Alphitobius diaperinus). Conclui-se que a alta frequência de parasitos presentes na cama de frango pode estar relacionada à falha de manejo.

The objective of this study was to evaluate the parasitic load of chicken litter from a poultry farm located in the municipality of Paço do Lumiar - MA. Fifty samples of chicken bed of 10 sheds were collected. This bed had already been used six times in the previous batches. For the parasitological analyzes the methods of Spontaneous Sedimentation, Sheather Method, Sporulation for the diagnosis of coccidia oocysts were used. Eggs of nematodes of the genera Strongyloides (72%), Heterakis (18%) and Ascaridia (10%) were identified. The larvae of the genus Strongyloides were the most prevalent, with a frequency of 97% of cases, followed by geohelminths (3%). There were 1200 Eimeria oocysts, in sporulation stage. Mites and kites were also found (Alphitobius diaperinus). It is concluded that the high frequency of parasites present in chicken litter may be related to management failure.
