La depresión y la demencia son las enfermedades neuro-psiquiátricas de mayor prevalencia en el adulto mayor. En la depresión de este tipo de población influyen factores biológicos y sociales que son modificables. Se realizó una revisión de la bibliografía desde el año 2000 con el objetivo de contribuir al conocimiento de la epidemiología de la depresión del adulto mayor. Se encontró que la prevalencia varía según la localidad, país y también según la herramienta utilizada para el diagnóstico. De la exposición de los factores de riesgo se desprende que la familia, la sociedad y el estado deben emprender acciones específicas para paliar especialmente los factores modificables como el apoyo social y la mejora de la calidad de vida de los ancianos.

Las Plantas de Tratamiento de Aguas Residuales (PTAR) son ambientes ideales para la recombinación de genes de resistencia a antibióticos (GRA) entre bacterias: colectan heces de miles de personas y las mezclan bajo condiciones que promueven el crecimiento bacteriano para convertir materia orgánica en inorgánica, usualmente en presencia de antibióticos de uso clínico y veterinario. Las aguas tratadas son descargadas en ríos y océanos o utilizados para la irrigación de cultivos y áreas verdes en la ciudad, promoviendo la reintroducción de bacterias resistentes y GRAs en el ambiente y en poblaciones humanas. Es así como los microbiomas de aguas residuales se convierten en potenciales reservorios de GRAs disponibles para patógenos humanos. Entre 2013 y 2015, realizamos muestreos mensuales de aguas pre y post-tratamiento de una PTAR de Lima que procesa residuos de casi un millón...

Latina women in the U.S. have relatively low breast cancer incidence compared to Non-Latina White (NLW) or African American women but are more likely to be diagnosed with the more aggressive "triple negative" breast cancer (TNBC). Latinos in the U.S. are a heterogeneous group originating from different countries with different cultural and ancestral backgrounds. Little is known about the distribution of tumor subtypes in Latin American regions. Clinical records of 303 female Peruvian patients, from the Peruvian National Cancer Institute, were analyzed. Participants were diagnosed with invasive breast cancer between 2010 and 2015 and were identified as residing in either the Selva or Sierra region. We used Fisher's exact test for proportions and multivariable Cox Proportional Hazards Models to compare overall survival between regions. Women from the Selva region were more likely to be dia...

The widespread and poorly regulated use of antibiotics in animal production in low- and middle-income countries (LMICs) is increasingly associated with the emergence and dissemination of antibiotic resistance genes (ARGs) in retail animal products. Here, we compared Escherichia coli from chickens and humans with varying levels of exposure to chicken meat in a low-income community in the southern outskirts of Lima, Peru. We hypothesize that current practices in local poultry production result in highly resistant commensal bacteria in chickens that can potentially colonize the human gut. E. coli was isolated from cloacal swabs of non-organic (n = 41) and organic chickens (n = 20), as well as from stools of market chicken vendors (n = 23), non-vendors (n = 48), and babies (n = 60). 315 E. coli isolates from humans (n = 150) and chickens (n = 165) were identified, with chickens showing highe...

Introduction: Breast cancer is a heterogeneous disease, and the distribution of the different subtypes varies by race/ethnic category in the United States and by country. Established breast cancer-associated factors impact subtype-specific risk; however, these included limited or no representation of Latin American diversity. To address this gap in knowledge, we report a description of demographic, reproductive, and lifestyle breast cancer-associated factors by age at diagnosis and disease subtype for The Peruvian Genetics and Genomics of Breast Cancer (PEGEN-BC) study. Methods: The PEGEN-BC study is a hospital-based breast cancer cohort that includes 1943 patients diagnosed at the Instituto Nacional de Enfermedades Neoplásicas in Lima, Peru. Demographic and reproductive information, as well as lifestyle exposures, were collected with a questionnaire. Clinical data, including tumor Horm...
