Proposta de um protocolo de reabilitação pulmonar em pacientes sobreviventes da COVID-19

Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 virus is a new disease characterized by generating lung damage and compromising multiple tissues and organs throughout the body. Some of the patients with the infection should need intrahospital management with O2 support and additional measures that may include prolonged ICU immobilization. Patients who have moderate or severe conditions and survive the disease, could experience long-term impairment and dysfunction, including pulmonary fibrosis, cardiomyopathy, renal, hepatic and peripheral nerve injury, and all complications arising from hospitalizations in the ICU. It is considered that intervention in pulmonary rehabilitation is particularly important, especially at the recovery stage, and should be performed mainly with the objectives of improving: dyspnea, severe muscle weakness and fatigue, in order to promote functional independence and increase quality of life, so that anxiety and depression are diminished.La enfermedad por coronavirus 2019 (COVID-19) causada por el virus SARS-CoV-2 es una nueva enfermedad caracterizada por generar daño pulmonar y compromiso de múltiples tejidos y órganos de todo el cuerpo.

Los pacientes que presentan cuadros moderados o severos y sobreviven a la enfermedad pueden presentar deterioro y disfunciones a largo plazo, incluyendo fibrosis pulmonar, miocardiopatía, lesión renal, hepática, de nervio periférico y todas las complicaciones derivadas de hospitalizaciones en UCI. Se considera que la intervención en rehabilitación pulmonar reviste gran importancia, especialmente en la etapa de recuperación, y debe realizarse, principalmente, con los objetivos de mejorar la disnea, la debilidad muscular severa y la fatiga, a fin de promover la independencia funcional y aumentar la calidad de vida, de manera que se disminuye así la ansiedad y la depresión.Doença por coronavírus (COVID-19), causada pelo vírus SARS-CoV-2, é uma nova doença caracterizada por gerar dano pulmonar e comprometimento de múltiplos tecidos e órgãos de todo o corpo.

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

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

New insights into the genetic etiology of Alzheimer’s disease and related dementias

Characterization of the genetic landscape of Alzheimer’s disease (AD) and related dementias (ADD) provides a unique opportunity for a better understanding of the associated pathophysiological processes. We performed a two-stage genome-wide association study totaling 111,326 clinically diagnosed/‘proxy’ AD cases and 677,663 controls. We found 75 risk loci, of which 42 were new at the time of analysis. Pathway enrichment analyses confirmed the involvement of amyloid/tau pathways and highlighted microglia implication. Gene prioritization in the new loci identified 31 genes that were suggestive of new genetically associated processes, including the tumor necrosis factor alpha pathway through the linear ubiquitin chain assembly complex. We also built a new genetic risk score associated with the risk of future AD/dementia or progression from mild cognitive impairment to AD/dementia. The improvement in prediction led to a 1.6- to 1.9-fold increase in AD risk from the lowest to the highest decile, in addition to effects of age and the APOE ε4 allele
