    The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

    El presente estudio se basó en la implementación del proceso de atención farmacéutica (seguimiento farmacoterapéutico) a pacientes ingresados en el servicio de hospitalización en la Clínica Cardiovascular del Caribe de Montería. El tipo de estudio para el desarrollo del presente trabajo fue observacional con enfoque trasversal, en el servicio de hospitalización durante el primer y segundo periodo del 2019 entre mayo y diciembre para identificar posibles Problemas Relacionados con la Medicación (PRM) y causales de estos mismos. Teniendo como resultado que en el servicio de hospitalización se detectaron 55 problemas relacionados con los medicamentos, donde el 3% corresponde a PRM de necesidad, el 55% de efectividad y el 42% de seguridad, siendo estos dos últimos los de mayor incidencia, convirtiéndose en cifras alarmantes que necesitan de intervención oportuna, para orientarlo a tomar acciones correctivas, en la búsqueda de que la implementación de seguimiento farmacoterapéutico ayude a la prevención oportuna de estos eventos.RESUMEN… ................................................................................................................ 161.

    Diminishing benefits of urban living for children and adolescents’ growth and development

    Optimal growth and development in childhood and adolescence is crucial for lifelong health and well-being1–6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5–19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was <1.1 kg m–2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified
