Objective: To determine the factors associated with COVID-19 mortality in the Central Highlands of Peru, specifically in the Department of Huánuco during 2020-2021. Methods: This quantitative, observational, analytical, and retrospective study collected medical records from 903 patients treated at the Amarilis Temporary Care and Isolation Center (CAAT, by its Spanish acronym) of the Hospital Materno Infantil (HMI) Carlos Showing Ferrari in Huánuco, Peru. The inferential analysis involved a bivariate logistic regression model and a multivariate predictive model to associate various factors with COVID-19 mortality. Results: The predictive logistic regression model identifed a COVID-19 mortality rate of 8.19% (74 patients). Factors significantly associated with increased mortality included advanced age (OR = 3.24; CI = 1.83 – 5.75), minimum oxygen saturation at admission (OR = 4.25; CI ...

Background: Guillain–Barre Syndrome (GBS) is considered a complex disorder with significant environmental effect and genetic susceptibility. Genetic polymorphisms in CD1E, CD1A, IL-17, and/or ICAM1 had been proposed as susceptibility genetic variants for GBS mainly in Caucasian population. This study explores the association between selected polymorphisms in these genes and GBS susceptibility in confirmed GBS cases reported in mestizo population from northern Peru during the most recent GBS outbreak of May 2018. Methods: A total of nine nonrelated cases and 11 controls were sequenced for the polymorphic regions of CD1A, CD1E, IL-17, and ICAM1. Results: We found a significant protective association between heterozygous GA genotype in ICAM1 (241Gly/Arg) and GBS (p '.047). IL-17 was monomorphic in both controls and patients. No significant differences were found in the frequency of SNPs ...

En Perú se ha estado trabajando en genética y genómica a pesar de la ausencia de inversión nacional. Proveedores multidisciplinarios en el cuidado de la salud han contribuido en el área de la genética en Perú. Se destaca varios ejemplos de logros en áreas clínicas y de investigación. El número de profesionales bien entrenados está aumentando, contribuyendo con colaboraciones nacionales e internacionales, investigación y experiencia clínica, que se incrementa en calidad y extensión. En estos tiempos donde mucha tecnología externa y estandarizada está emergiendo, la colaboración es muy importante para la investigación y se traduce en la implementación de medicina precisa para el sistema de salud pública.

Peru is a pluricultural and ethnically diverse country located in middle west of South America. It is the fourth largest country (1,285,216 km2) in area in South America, bordered in the north by Ecuador and Colombia, in the south by Chile, south east by Bolivia, by Brazil in the east and by the Pacific Ocean in the west. Peru has one of the most diverse climates, geographical and ecological in the world, from tropical or subtropical dessert to glacial in highland mountains to Amazon jungle. Peru is divided into 24 geopolitical regions with a central government. According to last national census in 2017, Peruvian populations accounts for 31,237,385 inhabitants (Instituto Nacional de Estadistica e Informatica [INEI], 2017). Most of Peru's population lives in the Coastal area, with almost one third of the nation's population living in Lima, the largest city with approximately 11 million pe...

Western South America was one of the worldwide cradles of civilization. The well-known Inca Empire was the tip of the iceberg of an evolutionary process that started 11,000 to 14,000 years ago. Genetic data from 18 Peruvian populations reveal the following: 1) The between-population homogenization of the central southern Andes and its differentiation with respect to Amazonian populations of similar latitudes do not extend northward. Instead, longitudinal gene flow between the northern coast of Peru, Andes, and Amazonia accompanied cultural and socioeconomic interactions revealed by archeology. This pattern recapitulates the environmental and cultural differentiation between the fertile north, where altitudes are lower, and the arid south, where the Andes are higher, acting as a genetic barrier between the sharply different environments of the Andes and Amazonia. 2) The genetic homogeniza...
