Prevalence of electrocardiographic alterations in athletes associated with cardiovascular risk parameters / Prevalencia de alteraciones electrocardiográficas en deportistas asociadas a parametros de riesgo cardiovascular

Sport induces cardiac adaptations that are manifested with specific electrocardiographic alterations. This study was carried out in view of the need to identify the relationship between these electrocardiographic alterations with cardiovascular and demographic variables and physical exercise performed. Methodology: a descriptive cross-sectional study in 370 individuals, 211 men and 159 women (36 ± 13 years) that were distributed in three groups: male athletes, female athletes, and non-athlete men and women. Results: 51.08% of the studied subjects presented electrographic alterations, more frequent in athletes. Demographic and cardiovascular variables and the time of physical exercise performed were significantly associated with certain electrocardiographic alterations; the risk of presenting any of the alterations in athletes could be estimated based on the variables set out. Conclusion: There are associations between specific electrocardiographic alterations and cardiovascular, demographic and type of exercise variables that could classify athletes according to cardiovascular risk profiles (AU)

A Questionnaire Survey of Personal and Occupational Variables Associated With SARS-COV-2 Infection in Health Care Personnel of the Spanish Central Military Hospital.

INTRODUCTION: Spain is the country with the highest number of health care workers affected by coronavirus disease 2019 (COVID-19) in the world. The aim of this study was to describe the epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) infection in health care worker (HCW) at the Gómez Ulla Military Hospital (HCDGU). MATERIALS AND METHODS: A case-control study was conducted during the first outbreak of COVID 19 at GUMH. The study was extended to the total number of HCW in the hospital who met the inclusion criteria. Health care worker of the HCDGU were civilian and military personnel that included nursing and medicine students of Spanish Military Academy, medicine specialty residents, and nursing residents of Medical Surgical Specialty in Operations (EMQO). A questionnaire of 33 items was prepared. The questionnaire was sent by e-mail to the entire population of study. With this questionnaire personnel were classified into sick (cases) or healthy. RESULTS AND CONCLUSIONS: One hundred fifty professionals answered the questionnaire. Cases were defined as those who tested positive in the diagnostic tests (n = 28, 20.7%) and no cases were those who tested negative (n = 107, 79.3%). Therefore, the percentage of SARS-CoV-2 in the GUMH was 20.7%. Of the total number of cases, 64.3% were men (P < .05), with a mean age of 47.1 years (SD 13.3), a mean BMI of 25.3 (SD 3.8), and 48.2% being overweight. Of the total cases, 59.3% had "A" blood group type and 69.2% were Rh positive. 50% were physicians, 32.1% were nurses, and 17.9% were auxiliary nurses (P < .05). Cases and controls with vitamin D deficiency and who took supplements had a lower risk of suffering COVID-19, with significant differences. Fever, cough, and diarrhea were found in at least 50% of the samples with significant differences.
