RESUMEN
INTRODUCTION: The intestinal microbiota comprises bacteria, fungi, archaea, protists, helminths and viruses that symbiotically inhabit the digestive system. To date, research has provided limited data on the possible association between an active lifestyle and a healthy composition of human microbiota. This review was aimed to summarize the results of human studies comparing the microbiome of healthy individuals with different physical activity amounts. METHODS: We searched Medline/Ovid, NIH/PubMed, and Academic Search Complete between August-October 2020. Inclusion criteria comprised: (a) cross-sectional studies focused on comparing gut microbiome among subjects with different physical activity levels; (b) studies describing human gut microbiome responses to any type of exercise stimulus; (c) studies containing healthy adult women and men. We excluded studies containing diet modifications, probiotic or prebiotic consumption, as well as studies focused on diabetes, hypertension, cancer, hormonal dysfunction. Methodological quality and risk of bias for each study were assessed using the Risk Of Bias In Non-randomized Studies-of Interventions tool. The results from cross-sectional and longitudinal studies are shown independently. RESULTS: A total of 17 articles were eligible for inclusion: ten cross-sectional and seven longitudinal studies. Main outcomes vary significantly according to physical activity amounts in longitudinal studies. We identified discrete changes in diversity indexes and relative abundance of certain bacteria in active people. CONCLUSION: As literature in this field is rapidly growing, it is important that studies incorporate diverse methods to evaluate other aspects related to active lifestyles such as sleep and dietary patterns. Exploration of other groups such as viruses, archaea and parasites may lead to a better understanding of gut microbiota adaptation to physical activity and sports and its potentially beneficial effects on host metabolism and endurance.

BACKGROUND: There is scarcity of data about the prevalence of non-AIDS defining comorbidities among stable HIV-infected patients in Peru. OBJECTIVE: We aimed to describe the most frequent cardiometabolic comorbidities found among ambulatory adults on ARV in Peru. METHODS: A review of records for patients attending regular visits at 5 clinics in Lima-Callao in January-February 2016 is presented. Patients were adults on ARV for >6 months, with no recent AIDS-defining condition. RESULTS: Three hundred and five medical charts were reviewed. Most patients were male (73.1%, n=223) with a mean age of 46.0 years. Mean time from HIV diagnosis was 9.41 yrs. and mean duration of ARV was 7.78 yrs. Most patients were on an NNRTI-based first line regimen (76.4%, n=233), and 12.1% (n=37) were on rescue regimens. Median CD4 count was 614.2 cells/µL and the proportion of patients with viral load <40 c/mL was 90.8% (n=277). Most frequent metabolic diagnoses were dyslipidemia (51.5%, n=157), obesity (11.1%, n=34), and diabetes mellitus (7.2%, n=22). Hypertension was diagnosed in 8.9% (n=27). Other diagnoses of cardiovascular disease were documented in 3.3% (n=10). Pharmacologic treatment was prescribed in 91.3% of patients with diabetes or hypertension, but in only 29.3% of patients with dyslipidemia. CONCLUSION: A high proportion of metabolic comorbidities was found, with dyslipidemia being the most frequent, followed by obesity and diabetes. In contrast, cardiovascular disease was documented less frequently. Medical treatment was started for only a third of dyslipidemia patients. HIV care policies need to consider proper management of chronic comorbidities to optimize long-term outcomes.
RESUMEN
Sedentary behaviors are associated with less physical activity. Little evidence exists about this association and its relation with commuting time in Latin America. This study examined the association between time spent traveling in motor vehicles and physical activity levels in the domains of leisure time physical activity and transportation, among Colombian adults in urban areas. A secondary data analysis of the 2010 National Nutrition Survey was conducted. Time spent traveling in motor vehicles and physical activity were assessed using the International Physical Activity Questionnaire. Binary logistic regressions were conducted. Time spent traveling in motor vehicles for 120 minutes or more was reported among 27.6% of the sample. The prevalence of walking and bicycling as a means of transportation for at least 150 minutes per week was 34% and 4.4%, respectively. Achieving at least 150 minutes of leisure time physical activity a week was reported by 18.4% of the sample. This study suggests negative associations between time spent traveling in motor vehicles and active transport, with significant trend associations in stratified analyses. No significant associations were found between time spent traveling in motor vehicles and leisure time physical activity.

Comportamientos sedentarios se asocian con una menor actividad física. Existen pocas evidencias sobre esta asociación en relación con el tiempo de viaje en América latina. Se examinó la asociación entre el tiempo de viaje en vehículos motorizados y los niveles de actividad física en los dominios de actividad física en el tiempo libre y transporte, en adultos colombianos de zonas urbanas. Se realizó un análisis de datos secundarios de la Encuesta Nacional de Nutrición de 2010. El tiempo de viaje en vehículos motorizados y actividad física se evaluó a través del Cuestionario Internacional de Actividad Física. Se llevaron a cabo regresiones logísticas binarias. Tiempo de viaje en vehículos motorizados durante 120 minutos o más, fue reportado por el 27,6% de la muestra. La prevalencia de caminar y montar en bicicleta como medio de transporte fue de 34% y 4,4%, respectivamente. Realizar por lo menos 150 minutos a la semana de actividad física en el tiempo libre fue reportado por el 18,4% de la muestra. Este estudio sugiere asociaciones negativas entre tiempo de viaje en vehículos motorizados y transporte activo, con tendencias significativas en análisis estratificados. No hubo diferencias significativas entre tiempo de viaje en vehículos motorizados y actividad física en el tiempo libre.

Este estudo sugere associações negativas entre tempo gasto viajando em veículos a motor e transporte ativo, com associações significativas de tendências na análise estratificada. Não houve diferenças significativas encontradas entre tempo gasto viajando em veículos a motor e atividade física de lazer.
RESUMEN
OBJETIVO: Conocer la prevalencia e infección por enteroparásitos, así como determinar el estado nutricional de una población escolar infantil aparentemente sana de la Institución Educativa Nacional ôKarol Wojtylaõ, del distrito de San Juan de Lurigancho, Lima-Perú. MATERIAL Y MÉTODO: 05 niños, de ambos sexos, entre 6 y 12 años de primer a sexto grado de primaria. Las muestras fueron analizadas utilizando la técnica de sedimentación espontánea (TSET) y el método de Graham. RESULTADOS: En el 44.4 % (91/205) se realizó el examen parasitológico. La prevalencia de enteroparásitos fue 61.50% (56/91), hallando Enterobius vermicularis (14.30%), Hymenolepis nana (8.80%), Blastocystis hominis (38.50%), y Giardia lamblia (13.20%) y no patógenos como Entamoeba coli (17.60%). CONCLUSIONES: Existe una alta prevalencia de parasitosis en la población escolar analizada, la que estuvo relacionada con el nivel sociocultural y económico. No se observó relación directa entre presencia de parásitos y deficiencia en el aprendizaje, ni con desnutrición.
OBJECTIVES: To determine the prevalence and degree of infection by intestinal parasites and to determine the nutritional status of apparently healthy infant school population that attends the National Educational Institution ôKarol Wojtylaõ in the district of San Juan de Lurigancho, Lima, Peru. MATERIAL AND METHODS: 205 children, both female and male between 6 and 12 years belonging to the sections of first through sixth grade. We used the spontaneous sedimentation technique (TSET) and the method of Graham. RESULTS: 44.4% (91/205) were made parasitological examination. The prevalence of intestinal parasites was 61.50% (56/91), finding the presence of Enterobius vermicularis (14.30%), Hymenolepis nana (8.80%), Blastocystis hominis (38.50%) and Giardia lamblia (13.20%) and pathogens such as Entamoeba coli (17.60%). CONCLUSIONS: There is a high prevalence of parasitosis in the school population tested, which is related to sociocultural and economic level of the settlers did not observe a direct relationship between the presence of parasites and poor learning. There was no relation between the presence of parasites and malnutrition.
