SENTRY antimicrobial surveillance program report: latin american and brazilian results for 1997 through 2001

Abstract: The alarming emergence and spread of antimicrobial resistance among common bacteria threatens the effectiveness of therapy for many infections. Surveillance of antimicrobial resistance is essential to identify the major problems and guide adequate control measures. Several resistance surveillance programs have been implemented in North America and Europe in the last decade; however, very few programs have assessed antimicrobial resistance in Latin American countries. The SENTRY Antimicrobial Surveillance Program was initiated in 1997 and represents the most comprehensive surveillance program in place at the present time worldwide. The SENTRY Program collects consecutive isolates from clinically documented infections in more than 80 medical centers worldwide (10 in Latin America). The isolates are collected according to the type of infection (objectives) and susceptibility tested in a central microbiology laboratory by reference broth microdilution methods according to NCCLS guidelines. The Program also incorporated molecular typing (ribotyping and PFGE) and resistance mechanism analysis of selected isolates. In this report we present a very broad analysis of the data generated by testing almost 20,000 bacterial isolates against more than 30 antimicrobial agents. The susceptibility results (MIC(50), MIC(90) and % susceptible) are presented in 11 tables according to the organism and site of infection. The data from Brazil, as well as the data from isolates collected in 2001, are analyzed separately. This report allows the evaluation of the activities numerous antimicrobial agents against clinical isolates collected in Latin American countries.

Physical exercise and osteoporosis: effects of different types of exercises on bone and physical function of postmenopausal women

Abstract: Physical exercise is an important stimulus for osteoporosis prevention and treatment. However, it is not clear yet which modality would be better to stimulate bone metabolism and enhance physical function of postmenopausal women. This review paper aims to summarize and update present knowledge on the effects of different kinds of aquatic and ground physical exercises on bone metabolism and physical function of postmenopausal women. Moderate to intense exercises, performed in a high speed during short intervals of time, in water or on the ground, can be part of a program to prevent and treat postmenopausal osteoporosis. Mechanical vibration has proven to be beneficial for bone microarchitecture, improving bone density and bone strength, as well as increasing physical function. Although impact exercises are recognized as beneficial for the stimulation of bone tissue, other variables such as muscle strength, type of muscle contraction, duration and intensity of exercises are also determinants to induce changes in bone metabolism of postmenopausal women. Not only osteoanabolic exercises should be recommended; activities aimed to develop muscle strength and body balance and improve the proprioception should be encouraged to prevent falls and fractures.

Necessidades de saúde e masculinidades: atenção primária no cuidado aos homens

Abstract: This study deals with the relations between masculinities and health care, approaching the recognition of health needs among male users of primary health care and the responses by the services. The study is part of a larger research project in four Brazilian States, with a convenience sample of eight health services. Ethnographic observation was compared with semi-structured interviews with 182 health care users from 15 to 65 years of age and 72 health professionals. Thematic analysis of the ethnographic records and interviews was based on gender references and studies on health work. The findings show how medicalization of health needs affects users, professionals, and services, disguising issues related to masculinity. Primary care focuses mainly on women, thereby reproducing gender inequalities in health services operations and professional performance, with women receiving disciplined care and men receiving insufficient attention and care.

PD-L1 expression as a predictive biomarker in advanced non-small-cell lung cancer: updated survival data.

Abstract: Aim: The treatment of non-small-cell lung cancer has changed after the development of the immune checkpoint inhibitors. Although the most studied biomarker is PD-L1 expression, its clinical significance is still debatable. In this article, we show the updated survival analysis of all published data. Methods: We searched in network and conference data sources for relevant clinical studies of immunotherapy for non-small-cell lung cancer that assessed the PD-L1 expression even as an exploratory analysis. The updated survival hazard ratios (HR) were included in the analysis. Results: 14 studies with 2857 patients were included (2019 treated with immunotherapy). The response rate was as higher among PD-L1-positive patients (RR: 2.19, 95% CI: 1.63–2.94). PD-L1 expression was also related to better progression-free survival (HR: 0.69, 95% CI: 0.57–0.85) and better overall survival (HR: 0.77, 95% CI: 0.67–0.89). Conclusion: PD-L1 overexpression predicts activity as well as better survival for patients treated wit...
