Gender Differences Regarding Self-Perceived Physical and Mental Health in Spanish University Sports and Physical Therapy Students after Termination of the COVID-19 Lockdown Period.

The COVID-19 pandemic was an unprecedented situation that raised concerns about the physical and mental health of adolescents. Several surveys demonstrated that post-lockdown, women reported more complaints and lower perceived quality of life compared to men. The aim of this study was to analyze gender differences in self-reported physical and mental health immediately after the second lock-down restrictions (July 2020 to December 2020) were suspended and physical exercise classes resumed after a break of several months. This was achieved using a comparative cross-sectional survey of over-18-year-old students from the faculties of Sports Science and Physical Therapy at the University of Cadiz (UCA) in Spain. Quality of life was assessed using two types of questionnaires. The first covered quality of nutrition (PREDIMED), and the second assessed emotional impact (SF12). Physical activity level was estimated using the International Physical Activity Questionnaire (IPAQ). Of the 166 participants in this study, about two-thirds were men. Men had a better perception of their overall health quality than women. In addition, men had significantly fewer limitations in performing activities of daily living than their female counterparts. In contrast, female university students had better coping strategies, that is, they were better able to handle the problems of daily life and did so with more composure, attention, and concentration. These findings highlight the differences in post-release recovery between men and women and can be used to develop programs to promote better living standards and services to reduce gender disparities, which can ultimately improve quality of life.

Dealing with missing data under stratified sampling designs where strata are study domains.

A quick count seeks to estimate the voting trends of an election and communicate them to the population on the evening of the same day of the election. In quick counts, the sampling is based on a stratified design of polling stations. Voting information is gathered gradually, often with no guarantee of obtaining the complete sample or even information in all the strata. However, accurate interval estimates with partial information must be obtained. Furthermore, this becomes more challenging if the strata are additionally study domains. To produce partial estimates, two strategies are proposed: (1) a Bayesian model using a dynamic post-stratification strategy and a single imputation process defined after a thorough analysis of historic voting information; additionally, a credibility level correction is included to solve the underestimation of the variance and (2) a frequentist alternative that combines standard multiple imputation ideas with classic sampling techniques to obtain estimates under a missing information framework. Both solutions are illustrated and compared using information from the 2021 quick count. The aim was to estimate the composition of the Chamber of Deputies in Mexico.

Complicaciones cardiovasculares en pacientes con la COVID-19 / Cardiovascular complications in COVID-19 patients

Introducción: La COVID-19 se presenta como una infección del tracto respiratorio inferior. Entre sus diversas manifestaciones extrapulmonares se encuentra el daño cardiovascular, y estas son las que se asocian a la morbimortalidad. Se realizó una búsqueda de información científica utilizando recursos de las bases de datos PubMed, PubMed Central, SciELO, Ebsco, ClinicalKey y Scopus. Las estrategias de búsqueda formuladas fueron: SARS-CoV-2, COVID-19, complicaciones cardiovasculares; en inglés y español. Objetivo: Describir las complicaciones cardiovasculares en pacientes con la COVID-19. Desarrollo: Existe una amplia diversidad de criterios en la literatura científica acerca del daño cardiovascular en el contexto de la infección por la COVID-19. Las complicaciones cardiovasculares reportadas son: la lesión miocárdica aguda, miocarditis aguda, arritmias cardiacas, síndrome coronario agudo, insuficiencia cardiaca aguda, daño valvular cardiaco, enfermedad tromboembólica venosa y shock. Conclusiones: Se describen las complicaciones cardiovasculares en pacientes con la COVID-19. La infección por SARS-CoV-2 ocasiona daño directo o indirecto en el miocardio, las válvulas cardiacas y el resto del sistema cardiovascular(AU)

Introduction: The COVID-19 typically presents as a lower respiratory tract infection. Among its various extrapulmonary manifestations is cardiovascular damage, and these are the ones that are most associated with morbidity and mortality. A search for scientific information was carried; resources were obtained from databases PubMed, PubMed Central, SciELO, Ebsco, ClinicalKey, and Scopus. The search strategies formulated were: SARS-CoV-2, COVID-19, Cardiovascular complications; as well as its translations into the English language. Objective: To describe the cardiovascular complications in patients with the COVID-19. Development: There is a wide diversity of criteria in the scientific literature regarding cardiovascular damage in the context of COVID-19 infection. Frequently reported cardiovascular complications are acute myocardial injury, acute myocarditis, cardiac arrhythmias, acute coronary syndrome, acute heart failure, heart valve damage, venous thromboembolic disease, and shock. Conclusions: Cardiovascular complications in COVID-19 carriers were described. SARS-CoV-2 infection causes direct or indirect damage to the myocardium, heart valves and the rest of the cardiovascular system(AU)

Evidence of vascular damage in dengue disease: demonstration of high levels of soluble cell adhesion molecules and circulating endothelial cells.

Clinical evidence suggests that vascular damage plays a key role in the pathophysiology of dengue hemorrhagic fever (DHF). In this study, the authors tested this hypothesis by examining the levels of soluble intercellular adhesion molecule and vascular cell adhesion molecule (sICAM-1 and sVCAM-1), and the presence of circulating endothelial cells (CECs), as evidence of vascular damage, in peripheral blood from DHF patients (n=13). A significant increase in plasma levels of sICAM-1 (n=12) and sVCAM-1 (n=13) was detected by enzyme-linked immunosorbent assay (ELISA) in DHF patients, compared with healthy individuals. Increased numbers of CECs, as detected by the expression of endothelial cell markers (ICAM-1, platelet cell adhesion molecule [PCAM]-1, and CD36) with flow cytometry, were observed in DHF patients (n=4), compared to healthy subjects. The high levels of sICAM-1 and sVCAM-1, together with the presence of CECs in DHF patients, provide further evidence of endothelium damage and activation in DHF patients.
