ABSTRACT Background: Covid-19 pandemic had an important impact on health care, on the approach to respiratory diseases. Aim: To characterize asthmatics patients hospitalized in a tertiary hospital during Covid-19 pandemic. Methods: Retrospective analysis of the clinical data of the patients hospitalized in our Hospital for asthma exacerbation during the first 12 months of Covid-19 pandemic (from March 2020 to February 2021) compared with the corresponding period before the pandemic (from March 2019 to February 2020). In order to identify admitted patients for asthma, we used ICD9 and ICD10 asthma. diagnostic codes attributed to the main diagnosis. Results: A total of 56 hospitalizations were identified, corresponding to 53 patients, 81.1% females and 18.9% males, with a mean age of 47.3 years [± 20.8 years; 8-93 years]. Ten cases were excluded (missing information, in three, and other reason for admission, in seven). We identified 17 hospitalizations in the considered pandemic period and 39 in the pre-pandemic period, representing a significant reduction in asthma hospitalization during covid-19 pandemic (30.4% vs 69.6%, p < 0.001). When comparing the main characteristics between the two groups (pandemic vs pre-pandemic), namely age (47.1 vs 47.3 years, p=0.972), gender (82.4% vs 79.5% female, p=1.0), atopy (50.0% vs 64.5%, p=0.366), hospitalization length (5.8 days vs 5.7 days, p=0.9), previous therapy (37.5% vs 30.8% only SABA/LABA, p=0.754), therapy after discharge (p=0.842) or exacerbation trigger, no statistical differences were found. In both groups, viral respiratory tract infection was the main trigger for asthma exacerbation. In neither case SARS-CoV-2 infection was identified. Conclusion: There was a significant decrease in asthma hospitalizations in the first 12 months of the Covid-19 pandemic, compared to the same period pre-pandemic. However, no statistically significant differences were found between the characteristics of hospitalized patients in the two periods.

RESUMO Introdução: A situação epidemiológica associada à infeção por SARS-CoV-2 modificou, desde o início, a prestação de cuidados de saúde em Portugal. Nesse sentido, visamos caracterizar os internamentos por asma num hospital terciário em contexto de pandemia Covid-19. Métodos: Análise retrospetiva dos processos clínicos dos doentes internados por asma num hospital universitário, durante 12 meses de pandemia (março 2020 a fevereiro 2021), comparativamente ao período homólogo pré-pandemia (março 2019 a fevereiro 2020). Foram utilizados os códigos ICD10 associados a “asma” atribuídos ao diagnóstico principal para identificar os doentes internados. Resultados: Globalmente observaram-se 56 internamentos, correspondentes a 53 doentes, 81,1% do sexo feminino, com uma média de idades de 47,3 anos [±20,8 anos; 8-93 anos]. Foram excluídos 10 doentes da análise, 2 por falta de informação e 8 porque o motivo de internamento não foi exacerbação de asma. No período de pandemia analisado observaram-se 17 internamentos e no período pré-pandemia 39, verificando-se uma redução significativa dos internamentos por asma (30,4% vs 69,6%, p < 0,001). Quando comparamos as principais características dos dois grupos (pandemia vs pré-pandemia), não se verificaram diferenças estatisticamente significativas, nomeadamente em termos de idade (47,1 vs 47,3 anos, p=0,972), sexo (82,4% vs 79,5% feminino, p=1,0), atopia (50,0% vs 64,5%, p=0,366), tempo de internamento (5,82 dias vs 5,67 dias, p=0,9), terapêutica prévia ao internamento (37,5% vs 30,8% exclusivamente SABA/LABA, p=0,754) ou à data da alta (p=0,842). Também não se observaram diferenças relativamente ao motivo de exacerbação da asma (p=0,452). Em ambos os grupos, o principal motivo foi a ocorrência de infeção respiratória, mas em nenhum dos casos foi identificada como infeção por SARS-CoV-2. Conclusões: Verificou-se uma diminuição do número de internamentos por asma nos primeiros 12 meses de pandemia, em comparação com o período homólogo prévio. Contudo, não se observaram diferenças estatisticamente significativas entre as principais características dos doentes internados por asma nestes dois períodos.

ABSTRACT The method of applying fertiliser to the soil affects grain productivity. The aim of this study was to determine the dynamics of phosphorus, potassium and sulphur in the arable layer of the soil during the third year of agricultural production, as a function of the method of application. The study took place in the district of Diamantino, Mato Grosso, in an area of soybean-maize succession under minimum tillage. Five treatments were tested in a randomised block design: no phosphorus or potassium (P0-K0); broadcast phosphorus and in-furrow potassium (Pb-Kf); in-furrow phosphorus and potassium (Pf-Kf); in-furrow phosphorus and broadcast potassium (Pf-Kb); broadcast phosphorus and potassium (Pb-Kb). When the soybeans reached physiological maturity, soil samples were collected from the 0-0.05, 0.05-0.10, 0.10-0.15 and 0.15-0.20 m layers for analysis of the pH, and P, K, S and organic matter content. The soil attributes were submitted to analysis of variance and Tukey’s test at 5%, and the nutrient dynamics in the soil profile were analysed by regression. The in-furrow application of phosphorus (Pf-Kb and Pf-Kf) improved P availability in the 0-0.05 m layer by 69.12% and 46.54% compared to the Pb-Kb treatment, by 73.93% and 50.71% compared to the Pb-Kf treatment, and by 136.77% and 105.16% compared to the P0-K0 treatment. The in-furrow application of phosphate fertiliser proved to be more effective in terms of phosphorus availability in the soil. The residual effect of broadcasting phosphate fertiliser on phosphorus availability in the soil can be seen from the third year of production onwards.

ABSTRACT BACKGROUND: The effect of weight loss (WL) on histopathological aspects of non-alcoholic fatty liver disease (NAFLD) may provide further insights into the dynamics of hepatic recovery after WL. OBJECTIVE: To analyze the effects of pre-operative WL on insulin resistance- and NAFLD-related histology in individuals undergoing bariatric surgery (BS) with or without pre-operative WL. DESIGN AND SETTING: A matched cross-sectional study was conducted at a public university hospital and a private clinic in Campinas, Brazil. METHODS: An analytical, observational, cross-sectional study was conducted using prospectively collected databases of individuals who underwent BS and liver biopsy at either a public tertiary university hospital (with pre-operative WL) or a private clinic (without pre-operative WL). Random electronic matching by gender, age, and body mass index (BMI) was performed and two paired groups of 24 individuals each were selected. RESULTS: Of the 48 participants, 75% were female. The mean age was 37.4 ± 9.6. The mean BMI was 38.9 ± 2.6 kg/m2. Fibrosis was the most common histopathological abnormality (91.7%). Glucose was significantly lower in the WL group (92 ± 19.1 versus 111.8 ± 35.4 mg/dL; P = 0.02). Significantly lower frequencies of macrovesicular steatosis (58.3% versus 95.8%; P = 0.004), microvesicular steatosis (12.5% versus 87.5%; P < 0.001), and portal inflammation (50% versus 87.5%; P = 0.011) were observed in the WL group. CONCLUSION: Pre-operative WL was significantly associated with lower frequencies of macro- and mi- crovesicular steatosis, portal inflammation, and lower glycemia, indicating an association between the recent trajectory of body weight and histological aspects of NAFLD.

RESUMO Objetivo: Analisar a influência dos fatores individuais e contextuais do hospital e do município de assistência sobre a sobrevida de pacientes com Síndrome Respiratória Aguda Grave por COVID-19. Métodos: Estudo de coorte hospitalar com dados de 159.948 adultos e idosos com Síndrome Respiratória Aguda Grave por COVID-19 internados de 01 de janeiro a 31 de dezembro de 2022 e notificados no Sistema de Informação de Vigilância Epidemiológica da Influenza. As variáveis contextuais foram relacionadas à estrutura, aos profissionais e equipamentos dos estabelecimentos hospitalares e indicadores socioeconômicos e de saúde dos municípios. O desfecho foi a sobrevida hospitalar em até 90 dias. Árvore de sobrevida e curvas de Kaplan-Meier foram utilizados para analisar a sobrevida. Resultados: A letalidade hospitalar foi de 30,4%. Idosos submetidos à ventilação mecânica invasiva e internados em cidades com baixo percentual de arrecadação de impostos apresentaram menor sobrevida quando comparados aos demais grupos identificados na árvore de sobrevida (p<0,001). Conclusão: O estudo indicou a interação de fatores contextuais com os individuais, e evidencia que características hospitalares e dos municípios aumentam o risco de óbito, destacando a atenção à organização, ao funcionamento e desempenho da rede hospitalar.

ABSTRACT Objective: To analyze the influence of individual and contextual factors of the hospital and the municipality of care on the survival of patients with Severe Acute Respiratory Syndrome due to COVID-19. Methods: Hospital cohort study with data from 159,948 adults and elderly with Severe Acute Respiratory Syndrome due to COVID-19 hospitalized from January 1 to December 31, 2022 and reported in the Influenza Epidemiological Surveillance Information System. The contextual variables were related to the structure, professionals and equipment of the hospital establishments and socioeconomic and health indicators of the municipalities. The outcome was hospital survival up to 90 days. Survival tree and Kaplan-Meier curves were used for survival analysis. Results: Hospital lethality was 30.4%. Elderly patients who underwent invasive mechanical ventilation and were hospitalized in cities with low tax collection rates had lower survival rates compared to other groups identified in the survival tree (p<0.001). Conclusion: The study indicated the interaction of contextual factors with the individual ones, and it shows that hospital and municipal characteristics increase the risk of death, highlighting the attention to the organization, operation, and performance of the hospital network.

El artículo tiene como objetivo analizar los efectos de la ampliación de la transferencia de recursos federal de enmiendas parlamentarias sobre el financiamiento municipal de la atención primaria de salud (APS) en el Sistema Único de Salud brasileño (SUS), en el período del 2015 al 2020. Se realizó un estudio longitudinal con datos secundarios de transferencias de recursos por enmiendas parlamentarias del Ministerio de Salud y de gastos con recursos propios de los municipios, aplicados a acciones y servicios públicos de salud y a la APS. El efecto de la transferencia de recursos de enmiendas parlamentarias sobre el financiamiento municipal se verificó de forma estratificada por tamaño de población de los municipios, utilizando modelos de ecuaciones de estimaciones generalizadas. La transferencia de recursos de enmiendas parlamentarias para la APS mostró una gran discrepancia en los valores per cápita entre municipios de diferente tamaño poblacional. No hubo correlación con el gasto municipal en acciones y servicios públicos de salud en aquellos con más de 10.000 habitantes y asociación inversa con el gasto en APS (p < 0,050) en todos los grupos de municipios. Se concluye que el aumento en la transferencia de recursos de enmiendas parlamentarias por parte del Ministerio de Salud favoreció la reducción de la asignación de ingresos municipales a la APS, que pueden haber sido dirigidos a otros fines de gasto en el SUS. Tales cambios parecen reflejar prioridades establecidas para el gasto presupuestario municipal, que repercuten en las condiciones locales para garantizar la estabilidad del financiamiento de la APS en Brasil.

O objetivo deste artigo é analisar os efeitos da ampliação do repasse federal de emendas parlamentares no financiamento municipal da atenção primária à saúde (APS) do Sistema Único de Saúde (SUS), no período de 2015 a 2020. Foi realizado estudo longitudinal com dados secundários de transferências por emendas parlamentares do Ministério da Saúde e de despesas com recursos próprios dos municípios, aplicadas em ações e serviços públicos de saúde e na APS. O efeito do repasse de emendas parlamentares no financiamento municipal foi verificado de forma estratificada por porte populacional dos municípios, por meio de modelos de equações de estimativas generalizadas. O repasse de emendas parlamentares para a APS apresentou grande discrepância de valores per capita entre os municípios de diferentes portes populacionais. Observou-se inexistência de correlação com a despesa municipal em ações e serviços públicos de saúde nos municípios com mais de 10 mil habitantes e associação inversa com a despesa em APS (p < 0,050) em todos os grupos. Conclui-se que o aumento do repasse de emendas parlamentares pelo Ministério da Saúde favoreceu a redução da alocação de receitas municipais com APS, que podem ter sido direcionados para outras finalidades de gasto no SUS. Tais mudanças parecem refletir prioridades estabelecidas para a despesa orçamentária dos municípios, que repercutem sobre as condições locais para a garantia da estabilidade do financiamento da APS no Brasil.

This study aims to analyze the effects of the expansion of the federal transfer of parliamentary amendments for municipal financing of primary health care (PHC) in the Brazilian Unified National Health System (SUS), from 2015 to 2020. A longitudinal study was conducted using secondary data on transfers of parliamentary amendments from the Brazilian Ministry of Health and expenditure of municipalities’ own resources on public health actions and services and PHC. The effect of the transfer of parliamentary amendments on municipal financing was verified in a stratified way by population size of the municipalities, using generalized estimating equation models. The transfer of parliamentary amendments for PHC showed a large discrepancy in per capita values among municipalities of different population sizes. No correlation with municipal spending on public health actions and services was observed in municipalities with more than 10,000 inhabitants, and the association with spending on PHC (p < 0.050) was inverse in all municipalities. Therefore, the increase in the transfer of parliamentary amendments by the Brazilian Ministry of Health favored a reduction in the allocation of municipal revenues to PHC, which may have been directed to other spending purposes in the SUS. These changes seem to represent priorities established for municipal budget expenditure, which have repercussions on local conditions for guaranteeing stable funding for PHC in Brazil.

ABSTRACT Introduction: Peritoneal dialysis patients are at increased risk of developing abdominal wall complications, including hernias. This study aimed to determine the incidence of hernias in peritoneal dialysis patients, identify risk factors, and evaluate their impact on technique survival. Methods: A retrospective cohort study was conducted, including prevalent peritoneal dialysis patients in a single center, from January 2010 to October 2020. Data on baseline characteristics, previous abdominal surgeries, and hernia history were collected. Patients with diagnosed hernias during peritoneal dialysis were compared to a control group. Results: Among 155 peritoneal dialysis patients, hernias occurred in 29% (n=45) of the population, with an incidence rate of 0.09 hernias/patient/year. Umbilical hernias were the most common subtype. Autosomal dominant polycystic kidney disease (OR (odds ratio) 3.925; 95% confidence interval (CI), 1.208 - 12.75) history of surgical repaired hernias (OR 5.586; 95% CI 1.540 - 20.255) and a higher number of previous abdominal surgeries (OR 1.680; 95% CI 1.025 - 2.752) were independent predictors of hernia development. Surgical treatment was performed in 59.3% of cases, with a 18.8% recurrence rate. Higher daytime infusion volumes were associated with hernia recurrence (p=0.045). Peritoneal dialysis technique survival did not differ significantly between the hernia and control groups (p=0.700). Conclusion: Hernias are frequent in peritoneal dialysis patients, with autosomal dominant polycystic kidney disease, previous abdominal surgeries, and history of surgically repaired hernias as identified risk factors. Hernias do not significantly interfere with peritoneal dialysis technique survival, but comprehensive management strategies, including early surgical repair and peritoneal dialysis prescription adaptations, can optimize outcomes.

ABSTRACT Objective: To assess the effect of atelectasis during mechanical ventilation on the periatelectatic and normal lung regions in a model of atelectasis in rats with acute lung injury induced by lipopolysaccharide. Methods: Twenty-four rats were randomized into the following four groups, each with 6 animals: the Saline-Control Group, Lipopolysaccharide Control Group, Saline-Atelectasis Group, and Lipopolysaccharide Atelectasis Group. Acute lung injury was induced by intraperitoneal injection of lipopolysaccharide. After 24 hours, atelectasis was induced by bronchial blocking. The animals underwent mechanical ventilation for two hours with protective parameters, and respiratory mechanics were monitored during this period. Thereafter, histologic analyses of two regions of interest, periatelectatic areas and the normally-aerated lung contralateral to the atelectatic areas, were performed. Results: The lung injury score was significantly higher in the Lipopolysaccharide Control Group (0.41 ± 0.13) than in the Saline Control Group (0.15 ± 0.51), p < 0.05. Periatelectatic regions showed higher lung injury scores than normally-aerated regions in both the Saline-Atelectasis (0.44 ± 0.06 x 0.27 ± 0.74 p < 0.05) and Lipopolysaccharide Atelectasis (0.56 ± 0.09 x 0.35 ± 0.04 p < 0.05) Groups. The lung injury score in the periatelectatic regions was higher in the Lipopolysaccharide Atelectasis Group (0.56 ± 0.09) than in the periatelectatic region of the Saline-Atelectasis Group (0.44 ± 0.06), p < 0.05. Conclusion: Atelectasis may cause injury to the surrounding tissue after a period of mechanical ventilation with protective parameters. Its effect was more significant in previously injured lungs.

RESUMO Objetivo: Avaliar o efeito da atelectasia durante a ventilação mecânica nas regiões periatelectáticas e pulmonares normais em um modelo de atelectasia em ratos com lesão pulmonar aguda induzida por lipopolissacarídeo. Métodos: Foram distribuídos aleatoriamente 24 ratos em quatro grupos, cada um com 6 animais: Grupo Salina-Controle, Grupo Lipopolissacarídeo-Controle, Grupo Salina-Atelectasia e Grupo Lipopolissacarídeo-Atelectasia. A lesão pulmonar aguda foi induzida por injeção intraperitoneal de lipopolissacarídeo. Após 24 horas, a atelectasia foi induzida por bloqueio brônquico. Os animais foram submetidos à ventilação mecânica por 2 horas com parâmetros ventilatórios protetores, e a mecânica respiratória foi monitorada durante esse período. Em seguida, foram realizadas análises histológicas de duas regiões de interesse: as áreas periatelectásicas e o pulmão normalmente aerado contralateral às áreas atelectásicas. Resultados: O escore de lesão pulmonar foi significativamente maior no Grupo Controle-Lipopolissacarídeo (0,41 ± 0,13) do que no Grupo Controle-Solução Salina (0,15 ± 0,51), com p < 0,05. As regiões periatelectásicas apresentaram escores maiores de lesão pulmonar do que as regiões normalmente aeradas nos Grupos Atelectasia-Solução Salina (0,44 ± 0,06 versus 0,27 ± 0,74, p < 0,05) e Atelectasia-Lipopolissacarídeo (0,56 ± 0,09 versus 0,35 ± 0,04, p < 0,05). O escore de lesão pulmonar nas regiões periatelectásicas foi maior no Grupo Atelectasia-Lipopolissacarídeo (0,56 ± 0,09) do que na região periatelectásica do Grupo Atelectasia-Solução Salina (0,44 ± 0,06), p < 0,05. Conclusão: A atelectasia pode causar lesão no tecido circundante após um período de ventilação mecânica com parâmetros ventilatórios protetores. Seu efeito foi mais significativo em pulmões previamente lesionados.

ABSTRACT Root canal morphology and its anatomical variations pose a great challenge to endodontists Aim The aim of this in silico study was to perform a qualitative and quantitative analysis of the threedimensional morphological characteristics of the isthmus in the mesial root canals of mandibular molars using microcomputed tomography (micro-CT) Material and Method Six hundred first mandibular molars were selected, including 317 with two mesial canals with isthmuses between the canals, and fully formed root. Isthmus morphology was determined in 3D longitudinal sections using Fan et al. (2010) classification. Root length, and the volume and area of apical and coronal level were measured. Additionally, the structural model index (SMI) of the canals were also assessed Results The prevalence of isthmuses in the mesial root canals was 32% type II, 29% type III, 22% type IV, and 17% type I. The root length was found to be 9.1±0.5 mm, the volume and area, of all root canal system, were 41.8±40.1 mm3 and 63.6±24.2 mm2 respectively. The isthmi volume and area alone were 11.06±9.03 mm3 and 30.02±11.02 mm2. The study confirmed that isthmuses are present in mesial canals of mandibular first molars, being more frequent in the apical third Conclusion The high prevalence of isthmuses with complex morphological features underscores the importance of using intracanal medications to disinfect areas unprepared by instruments.

RESUMO A morfologia do canal radicular e suas variações anatômicas representam um grande desafio para os endodontistas. O objetivo deste estudo ex vivo foi realizar uma análise qualitativa e quantitativa das características morfológicas tridimensionais do istmo nos canais mesiais de molares inferiores por meio de microtomografia computadorizada (micro-CT) Material e Método Foram selecionados 600 primeiros molares inferiores, incluindo 317 com dois canais mesiais com istmos e raiz totalmente formada. A morfologia do istmo foi determinada em cortes longitudinais 3D usando a classificação Fan et al. (2010). Foram mensurados o comprimento da raiz, o volume e a área apical e coronal e da cavidade pulpar. Adicionalmente, também foram avaliados o structure model index (SMI) dos canais Resultados A prevalência de istmos nos canais mesiais foi de 32% tipo II, 29% tipo III, 22% tipo IV e 17% tipo I. O comprimento da raiz foi de 9,1±0,5 mm, o volume e a área de todo o sistema de canais radiculares foram de 41.8±40.1 mm3 e 63.6±24.2 mm2, respectivamente. O volume e área do istmo isoladamente foram 11.06±9,03 mm3 e 30.02±11.02 mm2. O estudo confirmou que os istmos estão presentes em canais mesiais dos primeiros molares inferiores, sendo mais frequentes no terço apical Conclusão A alta prevalência de istmos com características morfológicas complexas ressalta a importância do uso de medicação intracanal para desinfecção de áreas não tocadas por instrumentos.

Abstract Background: Ultra-low-dose Spinal Anesthesia (SA) is the practice of employing minimal doses of intrathecal agents so that only the roots that supply a specific area are anesthetized. The aim of this study was to compare the effectiveness and safety of ultra-low-dose spinal anesthesia with that of Perineal Blocks (PB). Methods: A two-arm, parallel, double-blind randomized controlled trial comparing two anesthetic techniques (SA and PB) for hemorrhoidectomy and anal fistula surgery was performed. The primary outcomes were postoperative pain, complementation and/or conversion of anesthesia, and hemodynamic changes. Results: Fifty-nine patients were included in the final analysis. The mean pain values were similar in the first 48 h in both groups (p > 0.05). The individuals allocated to the SA group did not need anesthetic complementation; however, those in the PB group required it considerably (SA group, 0% vs. PB group, 25%; p = 0.005). Hemodynamic changes were more pronounced after PB: during all surgical times, the PB group showed lower MAP values and higher HR values (p < 0.05). Postoperative urinary retention rates were similar between both groups (SA group 0% vs. PB group 3.1%, p = 0.354). Conclusion: SA and PB are similarly effective in pain control during the first 48 h after hemorrhoidec-tomy and anal fistula surgery. Although surgical time was shorter among patients in the PB group, the SA technique may be preferable as it avoids the need for additional anesthesia. Furthermore, the group that received perineal blocks was under sedation with a considerable dose of propofol.

Abstract Background The use of the timed up and go (TUG) test to assess cardiorespiratory fitness in patients with heart disease has not been well defined in the literature. Objectives Test the association between TUG and peak oxygen consumption (VO2peak), construct an equation based on TUG to predict VO2peak, and determine a cutoff point to estimate VO2peak ≥ 20 mL/kg/min. Methods This cross-sectional study included 201 patients with coronary artery disease or heart failure, between 36 and 92 years of age, who underwent TUG and cardiopulmonary exercise test. Correlation, ROC curve, multiple linear regression, and Bland-Altman analyses were performed. The significance level was set at p < 0.05. Results The mean age of the total sample was 67 ± 13 years, and 70% of participants were male. The mean VO2peak was 17 ± 6 mL/kg/min, and the mean TUG time was 7 ± 2.5 seconds. The correlation between VO2peak and TUG was r = −0.54 (p < 0.001), and R2 was 0.30. The following equation was developed based on TUG: V O 2 peak = 33.553 + ( − 0.149 × age ) + ( − 0.738 × TUG ) + ( − 2.870 × sex ); a value of 0 was assigned to the male sex and 1 to the female sex (adjusted R: 0.41; adjusted R2: 0.40). The VO2peak estimated by the equation was 18.81 ± 3.2 mL/kg/min, and the VO2peak determined by cardiopulmonary exercise test was 18.18 ± 5.9 mL/kg/min (p > 0.05). The best cutoff point in the TUG for VO2peak ≥ 20 mL/kg/min was ≤ 5.47 seconds (area under the curve: 0.80; 95% confidence interval: 0.74 to 0.86). Conclusions TUG and VO2peak showed a significant association. A prediction equation for VO2peak was developed and validated internally with good performance. The cutoff point in the TUG to predict VO2peak ≥ 20 mL/kg/min was ≤ 5.47 seconds.

Resumo Fundamento A utilização do teste timed up and go (TUG) na avaliação da aptidão cardiorrespiratória em cardiopatas não está bem definida na literatura. Objetivos Testar a associação entre o TUG e o consumo de oxigênio de pico (VO2pico), construir uma equação com base no TUG para prever o VO2pico e determinar um ponto de corte para estimar um VO2pico ≥ 20 mL.kg−1.min−1. Métodos Estudo transversal com 201 indivíduos portadores de doença arterial coronariana ou insuficiência cardíaca, com idade entre 36 e 92 anos, submetidos ao TUG e ao teste cardiopulmonar de exercício. Foram realizadas análises de correlação, curva ROC, regressão linear múltipla e Bland-Altman. Um p < 0,05 foi adotado como significante. Resultados A média de idade da amostra total foi 67 ± 13 anos, e 70% dos participantes eram do sexo masculino. A média de VO2pico foi de 17 ± 6 mL.kg−1.min−1 e a média de desempenho no TUG foi de 7 ± 2,5 segundos. A correlação entre o VO2pico e o TUG foi r = −0,54 (p < 0,001) e R2 de 0,30. Foi desenvolvida a equação com base no TUG: V O 2 pico = 33 , 553 + ( − 0 , 149 ∗ idade ) + ( − 0 , 738 ∗ T U G ) + ( − 2 , 870 ∗ sexo ); sendo atribuído o valor 0 ao sexo masculino e 1 ao sexo feminino (R ajustado: 0,41; R2 ajustado: 0,40). O VO2pico estimado pela equação foi 18,81 ± 3,2 mL.kg−1.min−1 e o determinado pelo teste cardiopulmonar de exercício foi 18,18 ± 5,9 mL.kg−1.min−1 (p > 0,05). O melhor ponto de corte para o VO2pico ≥ 20 mL.kg−1.min−1 foi de ≤ 5,47 segundos (área sob a curva: 0,80; intervalo de confiança de 95%: 0,74 a 0,86). Conclusões O TUG e o VO2pico apresentaram associação significativa. A equação preditiva do VO2pico foi desenvolvida e validada internamente com bom desempenho. O ponto de corte no TUG para prever um VO2pico ≥ 20 mL.kg−1.min−1 foi ≤ 5,47 segundos.

Resumo O beribéri é a manifestação clínica da deficiência grave e prolongada de tiamina (vitamina B1). Doença negligenciada que acomete a população de baixa renda, em situação de insegurança alimentar e nutricional. O objetivo do estudo foi comparar casos de beribéri em indígenas com casos em não indígenas no Brasil. Trata-se de estudo transversal de casos notificados de beribéri no período de 2013 a 2018, no formulário do SUS (FormSUS) do Ministério da Saúde. Foram comparados os casos em indígenas e em não indígenas pelo teste qui-quadrado ou teste exato de Fisher com nível de significância de p < 0,05. No período estudado foram notificados no país 414 casos de beribéri, sendo 210 (50,7%) indígenas. Referiram consumo de bebidas alcoólicas 58,1% dos indígenas e 71,6% dos não-indígenas (p = 0,004); adicionalmente, 71,0% dos indígenas consumiam caxiri (bebida alcoólica tradicional fermentada). Relataram fazer esforço físico diário 76,1% dos indígenas e 40,2% dos não-indígenas (p <0 ,001). Conclui-se que o beribéri no país acomete mais indígenas e está relacionado ao consumo de álcool e ao esforço físico.

Abstract Beriberi is the clinical manifestation of severe and prolonged thiamine (vitamin B1) deficiency. It is a neglected disease that affects low-income populations facing food and nutrition insecurity. The aim of this study was to compare cases of beriberi among indigenous and non-indigenous people in Brazil. We conducted a cross-sectional study using data on cases of beriberi during the period July 2013-September 2018 derived from beriberi notification forms available on the FormSUS platform. Cases in indigenous and non-indigenous patients were compared using the chi-squared test or Fisher’s exact test, adopting a significance level of 0.05. A total of 414 cases of beriberi were reported in the country during the study period, 210 of which (50.7%) were among indigenous people. Alcohol consumption was reported by 58.1% of the indigenous patients and 71.6% of the non-indigenous patients (p = 0.004); 71.0% of the indigenous patients reported that they consumed caxiri, a traditional alcoholic drink. Daily physical exertion was reported by 76.1% of the indigenous patients and 40.2% of the non-indigenous patients (p < 0.001). It is concluded that beriberi disproportionately affects indigenous people and is associated with alcohol consumption and physical exertion.

Resumo O presente estudo objetivou verificar a associação entre aspectos psicossociais (capital social) e padrões alimentares em mulheres adultas. Realizou-se um estudo transversal, de base populacional, com uma amostra representativa de 1.128 mulheres, de 20 a 69 anos de idade, residentes na área urbana do município de São Leopoldo, Rio Grande do Sul, em 2015. Os padrões alimentares foram identificados com base na frequência de consumo alimentar e classificados em: saudável (frutas, vegetais e alimentos integrais), de risco (alimentos ultraprocessados) e brasileiro (arroz e feijão), enquanto o capital social foi avaliado por meio de uma escala de eficácia coletiva. Observou-se que 18,9% da amostra foi classificada com alta eficácia coletiva. Após ajuste para potenciais fatores de confusão, observou-se uma probabilidade 44% maior para adesão ao padrão saudável (RP [razão de prevalência] = 1,44; IC95% [intervalo de confiança de 95%]: 1,01-2,03; p = 0,040) e 71% maior para o padrão brasileiro (RP = 1,71; IC95%: 1,18-2,47; p = 0,004) entre as mulheres com um maior nível de eficácia coletiva, quando comparadas às com baixo nível de eficácia coletiva. Assim, este estudo verificou uma relação significativa entre aspectos psicossociais e consumo alimentar em mulheres.

Abstract The present study aimed to verify the association between psychosocial aspects (social capital) and food patterns in adult women. A cross-sectional, population-based study was conducted with a representative sample of 1,128 women, aged 20 to 69 years, living in the urban area of the municipality of São Leopoldo, Rio Grande do Sul, Brazil, in 2015. The food patterns were identified based on the frequency of food intake and classified as: healthy (fruits, vegetables, and whole foods), at-risk (ultraprocessed foods), and Brazilian (rice and beans), while social capital was evaluated using a collective efficacy scale. It was observed that 18.9% of the sample was classified with high collective efficacy. After adjusting for potential confounding factors, a 44% higher probability was observed for adherence to the healthy pattern (PR [prevalence ratio] = 1.44; 95%CI [95% confidence interval]: 1.01-2.03; p = 0.040) and 71% higher for the Brazilian pattern (PR = 1.71; 95%CI: 1.18-2.47; p= 0.004) among women with a higher level of collective efficacy, when compared to those with a low level of collective efficacy. Thus, this study verified a significant relationship between psychosocial aspects and food intake in women.

Abstract Beriberi is the clinical manifestation of severe and prolonged thiamine (vitamin B1) deficiency. It is a neglected disease that affects low-income populations facing food and nutrition insecurity. The aim of this study was to compare cases of beriberi among indigenous and non-indigenous people in Brazil. We conducted a cross-sectional study using data on cases of beriberi during the period July 2013-September 2018 derived from beriberi notification forms available on the FormSUS platform. Cases in indigenous and non-indigenous patients were compared using the chi-squared test or Fisher’s exact test, adopting a significance level of 0.05. A total of 414 cases of beriberi were reported in the country during the study period, 210 of which (50.7%) were among indigenous people. Alcohol consumption was reported by 58.1% of the indigenous patients and 71.6% of the non-indigenous patients (p = 0.004); 71.0% of the indigenous patients reported that they consumed caxiri, a traditional alcoholic drink. Daily physical exertion was reported by 76.1% of the indigenous patients and 40.2% of the non-indigenous patients (p < 0.001). It is concluded that beriberi disproportionately affects indigenous people and is associated with alcohol consumption and physical exertion.

Resumo O beribéri é a manifestação clínica da deficiência grave e prolongada de tiamina (vitamina B1). Doença negligenciada que acomete a população de baixa renda, em situação de insegurança alimentar e nutricional. O objetivo do estudo foi comparar casos de beribéri em indígenas com casos em não indígenas no Brasil. Trata-se de estudo transversal de casos notificados de beribéri no período de 2013 a 2018, no formulário do SUS (FormSUS) do Ministério da Saúde. Foram comparados os casos em indígenas e em não indígenas pelo teste qui-quadrado ou teste exato de Fisher com nível de significância de p < 0,05. No período estudado foram notificados no país 414 casos de beribéri, sendo 210 (50,7%) indígenas. Referiram consumo de bebidas alcoólicas 58,1% dos indígenas e 71,6% dos não-indígenas (p = 0,004); adicionalmente, 71,0% dos indígenas consumiam caxiri (bebida alcoólica tradicional fermentada). Relataram fazer esforço físico diário 76,1% dos indígenas e 40,2% dos não-indígenas (p <0 ,001). Conclui-se que o beribéri no país acomete mais indígenas e está relacionado ao consumo de álcool e ao esforço físico.

Abstract Objective To assess the risk factors involving longer hospital stays and early postoperative complications (first 30 days after surgery) in patients undergoing total knee arthroplasty (TKA). Materials and Methods Across-sectional study was conducted with collection of data of patients who underwent TKA in a private hospital between 2015 and 2019. The following data were collected: age, gender, body mass index, and clinical comorbid-ities. We also collected intraoperative data such as the grade on the classification of the American Society of Anesthesiologists (ASA), the duration of the surgery, the length of stay, the postoperative complications, and readmission within 30 days. Statistical models were used to investigate the possible risk factors associated with longer hospital stays and postoperative complications. Results There was evidence of an increase in the length of hospital stay in older patients, with higher grades on the ASA classification or who suffered postoperative complications. For each increase in 1 year of age, we expect the length of stay to be multiplied by 1.008 (95% confidence interval [95%CI]: 1.004 to 1.012; p < 0,001). In patients who were ASA grade III, the time is expected to be multiplied by 1.297 (95%CI: 1.083 to 1.554; p = 0,005) when compared with grade-I patients. In patients who suffered postoperative complications, the time is expected to be multiplied by 1.505 (95%CI: 1.332 to 1.700; p < 0.001) compared with patients without complications. Conclusion The present study demonstrated that, in patients who underwent primary TKA, preoperative characteristics such as older age and ASA grade > III, as well as the development of postoperative complications, independently predict the increase in the length of hospital stay.

Resumo Objetivo Avaliar os fatores de risco relacionados a um tempo de internação mais longo e às complicações pós-operatórias precoces (primeiros 30 dias após a cirurgia) em pacientes submetidos a artroplastia total do joelho (ATJ). Materiais e Métodos Este é um estudo transversal com coleta de dados de pacientes submetidos a ATJ em um hospital privado entre 2015 e 2019. Os seguintes dados foram coletados: idade, gênero, índice de massa corporal, e comorbidades clínicas. Também coletamos dados intraoperatórios, como o grau na classificação da American Society of Anesthesiologists (ASA) e a duração da cirurgia, além do tempo de internação, as complicações pós-operatórias, e a readmissão em 30 dias. Os possíveis fatores de risco associados a um tempo de internação mais longo e às taxas de complicações pós-operatórias foram investigados por meio de modelos estatísticos. Resultados Os pacientes mais velhos, com graus mais elevados na classificação da ASA ou que sofreram complicações pós-operatórias, ficaram internados por mais tempo. Para cada aumento em um ano de idade, esperamos que o tempo de internação seja multiplicado por 1,008 (intervalo de confiança de 95% [IC95%]: 1,004 a 1,012; p < 0,001). Em pacientes de grau III na classificação da ASA, espera-se que o tempo seja multiplicado por 1,297 (IC95%: 1,083 a 1,554; p = 0,005) em comparação com pacientes de grau I. Em pacientes com complicações pós-operatórias, espera-se que o tempo seja multiplicado por 1,505 (IC95%: 1,332 a 1,700; p < 0,001) em comparação com pacientes sem complicações. Conclusão Este estudo demonstrou que, em pacientes submetidos a ATJ primária, características pré-operatórias, como idade avançada e grau ≥ III na classificação da ASA, e o desenvolvimento de complicações pós-operatórias predizem o aumento do tempo de internação hospitalar de forma independente.
