The continuous flow of new research articles on MDR-TB diagnosis, treatment, prevention and rehabilitation requires frequent update of existing guidelines. This review is aimed at providing clinicians and public health staff with an updated and easy-to-consult document arising from consensus of Global Tuberculosis Network (GTN) experts.The core published documents and guidelines have been reviewed, including the recently published MDR-TB WHO rapid advice and ATS/CDC/ERS/IDSA guidelines.After a rapid review of epidemiology and risk factors, the clinical priorities on MDR-TB diagnosis (including whole genome sequencing and drug-susceptibility testing interpretations) and treatment (treatment design and management, TB in children) are discussed. Furthermore, the review comprehensively describes the latest information on contact tracing and LTBI management in MDR-TB contacts, while providing guidance on post-treatment functional evaluation and rehabilitation of TB sequelae, infection control and other public health priorities.

O objetivo do estudo é comparar a qualidade de vida de estudantes de Medicina do primeiro período e do último período do curso. Foi realizado um estudo transversal com a aplicação do instrumento da Organização Mundial da Saúde para avaliação da qualidade de vida no seu formato curto (Whoqol-bref) em 370 estudantes de Medicina da cidade do Recife, Brasil - 229 do primeiro e 141 do último período. Os resultados mostraram que os escores do domínio psicológico foram menores nos alunos do último período do que nos do primeiro período (p < 0,005). Essa diferença se manteve após a análise pelo modelo de covariância (Ancova). Em relação aos escores do domínio físico, relações sociais e meio ambiente, não houve diferenças significativas entre os alunos do primeiro e do último período. Quanto à autoavaliação da qualidade de vida, os alunos do primeiro período apresentaram melhores resultados (3,87 vs. 3,39; p < 0,001). Quanto à satisfação com a própria saúde, não houve diferença estatística; 3,94 vs. 3,62 (p = 0,099). Em conclusão, a qualidade de vida dos estudantes de Medicina, quando avaliada pelo instrumento Whoqol-bref, sofre desgastes no domínio psicológico durante o curso médico. Novos estudos são necessários para identificar os fatores que determinam essas alterações na qualidade de vida dos estudantes de Medicina durante a graduação.

Few studies have been conducted on the effects of aerobic exercise in children with asthma, particularly on the inflammatory component and functional outcomes. This study evaluated the effect of aerobic exercise on inflammation, functional capacity, respiratory muscle strength, quality of life and symptoms scores in asthmatic children. This was a 6-week randomized trial (NCT0192052) of 33 moderately asthmatic children (6-17 years). Patients were randomized aerobic training (exercise group; n = 14), while another group did not exercise (control; n = 19). Primary endpoint was evaluations serum cytokines (IL-17, IFN, TNF, IL-10, IL-6, IL-4 and IL-2) assessed by flow cytometry. The six-minute walk test, pulmonary function, quality of life and symptoms (asthma-free days) were secondary endpoint. The Mann-Whitney test was used to evaluate the independent variables and the Wilcoxon test for paired variables. The t-test was used for the remaining calculations. Significance was determined at 5%. Aerobic training failed to modify the inflammatory component. In the exercise group, an increase occurred in functional capacity (p < 0.01) and peak expiratory flow (p = 0.002), and maximal inspiratory (p = 0.005) and expiratory pressure (p < 0.01) improved. Furthermore, there was a significant increase in all the domains of the PAQLQ. The children who exercised had more asthma-free days than the controls (p = 0.012) and less sensation of dyspnea at the end of the study (p < 0.01). In conclusion, six weeks of aerobic exercise no changes in plasma cytokine patterns in asthmatic children and adolescents; however, an improvement was found in functional capacity, maximal respiratory pressure, quality of life and asthma-related symptoms.

IntroductionThe incidence of cancer is increasing worldwide and with it the prevalence of malnutrition, which is responsible for the death of almost 20 % of cancer patients. The objective of this study was to identify the factors associated with malnutrition in hospitalized cancer patients.MethodsCross-sectional study conducted with 277 hospitalized patients in the Institute of Integrative Medicine Prof. Fernando Figueira from March to November 2013. The nutritional status was classified as well-nourished and moderate/severe malnutrition, according to the Patient-Generated Subjective Global Assessment. The association between moderate/severe malnutrition and demographic, behavioral, socioeconomic, clinical, therapeutic and nutritional variables was investigated through univariate regression and hierarchical Poisson models, with a 5 % significance level.ResultsThe prevalence of malnutrition was 71.1 %, being classified as moderate in 35.4 % and severe in 35.7 %. After multivariate analysis, smokers/ex-smokers low socioeconomic status, performance status ≥2 and age ≥60 years were associated with increased risk of malnutrition.ConclusionThere was observed a high prevalence of moderate/severe malnutrition in cancer patients, with the increased risk of malnutrition associated with the presence of factors that can be assessed during hospital admission suggesting a higher alert of the medical and health care staff about the need for nutritional assessment and intervention.

IntroductionAnemia is a nutritional problem of global importance. It is estimated that at least one-third of the population has been at one time anemic.ObjectiveTo evaluate the prevalence of anemia and associated factors in patients of a children's hospital in Recife.MethodsA cross-sectional study was developed involving 595 male and female children aged from 6 to 59 months old, who were hospitalized in 2007.ResultsChildren with a hemoglobin concentration less than 11 g/dL were considered anemic. The relationship between studied variables and anemia was evaluated by Poisson regression analysis. There was a 56.6% prevalence of anemia (95% CI: 46.6-54.6). Anemia was significantly correlated with low weight (Prevalence ratio - PR = 1.39; 95% CI: 1.18-1.64), young age (PR = 2.01; 95% CI: 1.57-2.56) and a diagnosis of acute lower respiratory disease (PR = 1.57; 95% CI: 1.27-1.96).ConclusionThe high prevalence of anemia suggests that it may contribute as a causal factor for hospitalization, especially because the period of hospitalization was short and the patient was likely to be anemic at the time of admission. This study stresses the importance of evaluating the overall nutritional status of patients, including their ingestion of microelements. This is especially important in children, because of their greater susceptibility to anemia. Measures directed at the prevention and control of anemia, including increased coverage of supplementation and fortification programs are strongly recommended.
