Background: Sarcopenia is an important public health problem that affects mainly elders, and has negative consequences, such as disability and even death. Due to the lack of studies evaluating sarcopenia in elderly persons hospitalized in Brazil, the aim of the present study was to describe the frequency of sarcopenia and associated factors among elders in a hospital in the city of Salvador -Brazil. Methods: This cross-sectional study included 110 hospitalized elderly patients in a multi-specialty hospital in Salvador-BA, Brazil. Inclusion criteria: were elders aged ≥60 years between the first and fifth day of hospitalization; who were able to walk without external assistance; with medical permission to walk, and who did not take vasoactive and inotropic drugs. The diagnosis of sarcopenia was determined by combining the reduction in skeletal muscle mass with muscle weakness (women, <20 kg; men, <30 kg) and/or poor physical performance (gait speed ≤0.8 m/s). To obtain reduced skeletal muscle mass, the skeletal muscle mass index ≤6.37 kg/m 2 for women and ≤8.90 kg/m 2 for men was used. Cognitive function, Charlson index, admission profile (clinical and surgical), smoking, falls suffered in the last year and physical inactivity prior to admission were also evaluated. The frequency of sarcopenia was described in percentages with their respective confidence intervals and logistic regression was performed for multivariate analysis of factors associated with sarcopenia. Results: Among the 110 patients included, the frequency of sarcopenia was 21.8%, with 10.0% being of the severe type. There was a predominance of clinical profile (59.1%), such as heart disease (20.0%), pneumonia (13.6%) and skin infections (9.1%), with a Charlson index of 5.4 ± 1.8. The factors associated with sarcopenia were age (OR = 1.14; 95% CI = 1.06 to 1.23), clinical profile on admission (OR = 5.15; 95% CI = 1.16-22.9) and smoking (OR = 7.8; 95% CI = 1.53-39.9). Conclusions: The frequency of sarcopenia in elderly hospitalized patients was high (1 in 5 elderly) and anthropometric equation can be a viable and inexpensive alternative to screening and programming intervention in this population.

Chronic obstructive pulmonary disease (COPD) is now a major public health concern; deaths attributable to COPD in Latin America have increased by 65.0% in the last decade. This study was aimed at evaluating COPD prevalence and associated factors in adults (> 40 years) living in Greater Metropolitan São Paulo, Brazil. The study is part of the Proyecto Latinoamericano de Investigación en Obstrucción Pulmonar (The PLATINO Project), a multi-center survey on COPD burden in Latin America, with São Paulo as the first center where the project has been carried out. A population-based sample was selected in multiple stages. Spirometry tests were performed in each subject pre- and post-bronchodilator and COPD was mainly defined as the ratio of forced expiratory volume to forced vital capacity below 70.0% (fixed ratio definition). Other spirometric criteria were also used for the diagnosis of COPD. COPD prevalence was 15.8% (95%CI: 13.5-18.1) using the fixed ratio definition. COPD was positively associated with age and smoking and inversely with body mass index. Utilization of different COPD spirometry criteria resulted in different percentages of COPD, but similar associated factors.

OBJECTIVES:The ability of the Timed Up and Go test to predict sarcopenia has not been evaluated previously. The objective of this study was to evaluate the accuracy of the Timed Up and Go test for predicting sarcopenia in elderly hospitalized patients.METHODS:This cross-sectional study analyzed 68 elderly patients (≥60 years of age) in a private hospital in the city of Salvador-BA, Brazil, between the 1st and 5th day of hospitalization. The predictive variable was the Timed Up and Go test score, and the outcome of interest was the presence of sarcopenia (reduced muscle mass associated with a reduction in handgrip strength and/or weak physical performance in a 6-m gait-speed test). After the descriptive data analyses, the sensitivity, specificity and accuracy of a test using the predictive variable to predict the presence of sarcopenia were calculated.RESULTS:In total, 68 elderly individuals, with a mean age 70.4±7.7 years, were evaluated. The subjects had a Charlson Comorbidity Index score of 5.35±1.97. Most (64.7%) of the subjects had a clinical admission profile; the main reasons for hospitalization were cardiovascular disorders (22.1%), pneumonia (19.1%) and abdominal disorders (10.2%). The frequency of sarcopenia in the sample was 22.1%, and the mean length of time spent performing the Timed Up and Go test was 10.02±5.38 s. A time longer than or equal to a cutoff of 10.85 s on the Timed Up and Go test predicted sarcopenia with a sensitivity of 67% and a specificity of 88.7%. The accuracy of this cutoff for the Timed Up and Go test was good (0.80; IC=0.66-0.94; p=0.002).CONCLUSION:The Timed Up and Go test was shown to be a predictor of sarcopenia in elderly hospitalized patients.

O abandono do tratamento da tuberculose tem implicações sociais e epidemiológicas. Objetivos: Comparar características de pacientes que abandonaram o tratamento com os que não o abandonaram (controle), matriculados no CS-EPM/Unifesp, no período de 1995 a 1997, e verificar se os grupos educativos de sala de espera diminuíram a ocorrência dos abandonos. Método: Foi realizado estudo retrospectivo controlado com 100 pacientes (38 abandonos pareados para 62 controles) matriculados para tratamento de tuberculose, em que se verificaram as variáveis mais relacionadas ao abandono. Destes, 60 pacientes participaram voluntariamente de grupos educativos (16 abandonos e 44 controles). Resultados: As variáveis mais relacionadas ao abandono foram: sexo masculino, tabagismo, alcoolismo, uso de drogas, presença de fatores de risco para HIV e internação prévia. Os que participaram voluntariamente dos grupos educativos de sala de espera tinham características semelhantes ao total de pacientes estudados, mas houve menor ocorrência de abandono durante o tratamento (p < 0,05). Conclusão: Os autores concluem que, tendo-se amplamente disponíveis os meios para diagnóstico e seguimento dos pacientes com tuberculose, todos os esforços possíveis deverão estar concentrados para evitar o abandono, sobretudo nos pacientes de risco, que deverão ter à sua disposição grupos educativos sobre a doença.
