ABSTRACT
OBJECTIVE: To assess the effectiveness of various sealing techniques in cholecystotomies under maximum intraluminal pressure stress using an ex vivo swine model. SAMPLE: 30 gallbladders from different animals were used. METHODS: The experiment was conducted ex vivo, with the formation of 3 groups, each comprising 10 samples. Group 1 utilized a traditional single-layer Cushing suture made from polydioxanone material. Group 2 employed a single layer of Cushing suture, also made from polydioxanone material, but in conjunction with surgical glue (n-butyl cyanoacrylate). Group 3 relied solely on the use of surgical glue (n-butyl cyanoacrylate) for sealing the edges of the surgical wound. The intraluminal pressure was gauged with a pressure transducer. RESULTS: The maximum intraluminal pressures (mean ± SD) sustained in G1, G2, and G3 were, respectively, 48.70 ± 21.32 mm Hg, 110.90 ± 37.52 mm Hg, and 10.9 ± 4.07 mm Hg. Comparisons between groups showed that G2 supported significantly higher pressures (56.1% higher) than G1 (P < .001) and G3 (90.2% higher; P < .001). When G1 was compared with G3, a significantly higher pressure (77.6%) was also observed (P < .01). CLINICAL RELEVANCE: The study's conclusions demonstrated the safest suture techniques for the gallbladder and provided advice regarding the use of surgical glue.

INTRODUCTION: Health problems may negatively affect the psychological and physical aspects of life, influencing the quality of life of older adults. The objective of this study was to analyze the effects of physical activity on quality of life, anxiety, and depression in the elderly population. METHODS: We performed a cross-sectional study of 200 elderly people of both genders. Subjects were divided into two groups: one with 100 senior citizens engaged in physical activities in a social center for the elderly; and another composed of 100 subjects who lived in the community but were not engaged in physical activities. The instruments used to assess physical activities, quality of life, and anxiety and depression were, respectively: the modified Baecke questionnaire; the 36-Item Short Form Health Survey (SF-36); and the Hospital Anxiety and Depression Scale (HADS). The data were analyzed using the Student's t test, Pearson's r, and analysis of variance (ANOVA), with odds ratio and a 5% significance level (p<0.05). RESULTS: We observed that the active group showed higher scores of physical activity and quality of life. Conversely, the sedentary group revealed higher scores of anxiety and depression. Data assessment revealed a strong correlation between the domains quality of life, level of vitality, and mental health (r=0.77). The prevalence ratio showed that physical activity is a protective factor against anxiety and depression in the elderly. CONCLUSION: The findings suggest a correlation between low levels of physical activity and symptoms of anxiety and depression in the elderly living in the community.

Resumo Introdução: Problemas de saúde podem afetar negativamente nos aspectos físicos e psicológicos, influenciando a qualidade de vida dos idosos. O objetivo deste estudo foi analisar os efeitos da atividade física sobre a qualidade de vida, ansiedade e depressão na população idosa. Métodos: Foi realizado estudo transversal com 200 idosos de ambos os sexos, divididos em dois grupos: um grupo com 100 idosos envolvidos em atividades físicas do centro social para idosos; outro composto por 100 sujeitos que viviam na comunidade, mas não estavam envolvidos em atividades físicas. Os instrumentos utilizados para avaliação das atividades físicas, qualidade de vida, ansiedade e depressão foram, respectivamente: o questionário de Baecke modificado; o Questionário de Qualidade de Vida (SF-36); e a Escala Hospitalar de Ansiedade e Depressão (HADS). Os dados foram analisados por testes t de Student, Pearson (r) e análise de variância (ANOVA), com odds ratio e nível de significância de 5% (p<0,05). Resultados: Observamos que o grupo ativo apresentou maiores escores de atividade física e qualidade de vida. Por outro lado, o grupo sedentário revelou maiores escores de ansiedade e depressão. A avaliação dos dados revelou uma forte correlação entre os domínios qualidade de vida, nível de vitalidade e saúde mental (r=0,77). A razão de prevalência mostrou que a atividade física é fator de proteção contra ansiedade e depressão em idosos. Conclusão: Os achados sugerem uma correlação entre baixos níveis de atividade física e sintomas de ansiedade e depressão em idosos que vivem na comunidade.
