Abstract Background: In pandemic times, social isolation is of utmost importance to minimize the spread of the SARS-Cov-2 virus. At times like these, home fitness becomes extremely necessary to avoid sedentarism and decompensation in chronic disease patients. Objectives: Evaluate the engagement of rehabilitation patients to a tele- oriented exercise program at home (TOEP). Materials and Methods: 66 of 94 patients (63.8% males; 65.5±14 years old; 5.2±2.6 months in rehabilitation) agreed to take part. Subjects were grouped in three levels of functionality to guide the exercise prescription. Weekly Training Rates (WTR) were compared using the Friedman test and corrected by Dunn's test. A multivariate logistic model was designed to determine independent predictors in program engagement. Statistical significance was determined by a p<0.05. Results: TOEP provided WTR similar to the pre-quarantine values of 2.8/week (p>0.05), and 91.8% of patients took part until the end of those 5 weeks. The presence of diabetes was a predicted factor for low engagement to TOEP with relative risk of 0.41 (CI95%: 0.25 to 0.66). Conclusion: TOEP provided satisfactory engagement in rehabilitation patients. Most of them increased WTR during quarantine. Patients with diabetes displayed lower engagement to the minimum standard frequency. Background SARSCov2 SARSCov SARS Cov 2 SARS-Cov- virus these Objectives tele TOEP. .

Abstract Background The SARS-COV2 pandemic has deeply affected the availability for training and competing for recreational and professional athletes. However, to date, the disease’s course among the athletic population has not been *studied . Objectives To compare the observed and expected rates of hospitalization for COVID-19 and to establish relationships between demographics and sportive characteristics of an athletic sample, and the COVID-19 infection rate. Material and Methods This study uses cross-sectional data sampling through an online questionnaire to collect data from recreational and professional athletes. Based on self-reports, athletes were grouped in COVID-19 and Non-COVID-19 cases. To decrease detection bias for each four patients who reported being hospitalized, one additional virtual patient was added to the sample. The observed rate of hospitalization (ORH) was compared with age expected rate of hospitalization (ERH) from the literature data. A multivariate model (MM) was developed to establish independent relationships between the prevalence of COVID-19 cases and the variables mentioned above. The statistical significance level was defined for a p-value<0.05. Results Answers from 1,701 individuals were analyzed. The COVID-19 group was comprised of 99 (5.8%) individuals, four of whom reported having been hospitalized. ORH and ERH were respectively of 5.0% and 18.1% (p=0.001). In the MM female gender (OR=2.02, 95% CI 1.28 to 3.19), cycling (OR=2.91, 95% CI 1.58 to 5.39), swimming (OR=2.97, 95% CI 1.14 to 7.74), and triathlon (OR=2.10, 95% CI 1.13 to 3.91) were independently associated with a COVID-19 prevalence. Conclusion Self-reported rates of hospitalization for COVID-19 among athletes were much lower than expected. The prevalence of positive cases of COVID-19 was independently higher for cyclists, triathletes, and swimmers than for runners.

Resumo Fundamento: Exame físico e peptídeo natriurético do tipo B (BNP) foram usados para estimar a hemodinâmica e adequar a terapia de pacientes com insuficiência cardíaca aguda descompensada (ICAD). Entretanto, correlação entre esses parâmetros e a pressão de enchimento do ventrículo esquerdo é controversa. Objetivo: Avaliar a acurácia diagnóstica do exame físico, da radiografia de tórax (RT) e do BNP para estimar a pressão atrial esquerda (PAE) avaliada pelo ecodopplercardiograma tecidual. Métodos: Pacientes admitidos com ICAD foram avaliados prospectivamente. As características diagnósticas dos sinais físicos de insuficiência cardíaca, RT e BNP para predizer elevação da PAE (> 15 mmHg), isolados ou combinados, foram calculadas. Teste de Spearman foi usado para analisar a correlação entre variáveis de distribuição não normal. O nível de significância foi 5%. Resultados: Este estudo incluiu 43 pacientes com idade média de 69,9 ± 11,1 anos, fração de ejeção ventricular esquerda de 25 ± 8.0%, e BNP de 1057 ± 1024,21 pg/mL. Individualmente, todos os parâmetros clínicos, RT e BNP apresentaram fraco desempenho para predizer PAE ≥ 15 mmHg. O escore clínico de congestão teve o pior desempenho [área sob a curva receiver operating characteristic (AUC) 0,53], seguindo-se escore clínico + RT (AUC 0,60), escore clínico + RT + BNP > 400 pg/mL (AUC 0,62) e escore clínico + RT + BNP > 1000 pg/mL (AUC 0,66). Conclusão: Exame físico, RT e BNP tiveram desempenho fraco para predizer PAE ≥15 mmHg. O uso desses parâmetros isoladamente ou em combinação pode levar a estimativa imprecisa do perfil hemodinâmico.

Abstract Background: Physical examination and B-type natriuretic peptide (BNP) have been used to estimate hemodynamics and tailor therapy of acute decompensated heart failure (ADHF) patients. However, correlation between these parameters and left ventricular filling pressures is controversial. Objective: This study was designed to evaluate the diagnostic accuracy of physical examination, chest radiography (CR) and BNP in estimating left atrial pressure (LAP) as assessed by tissue Doppler echocardiogram. Methods: Patients admitted with ADHF were prospectively assessed. Diagnostic characteristics of physical signs of heart failure, CR and BNP in predicting elevation (> 15 mm Hg) of LAP, alone or combined, were calculated. Spearman test was used to analyze the correlation between non-normal distribution variables. The level of significance was 5%. Results: Forty-three patients were included, with mean age of 69.9 ± 11.1years, left ventricular ejection fraction of 25 ± 8.0%, and BNP of 1057 ± 1024.21 pg/mL. Individually, all clinical, CR or BNP parameters had a poor performance in predicting LAP ≥ 15 mm Hg. A clinical score of congestion had the poorest performance [area under the receiver operating characteristic curve (AUC) 0.53], followed by clinical score + CR (AUC 0.60), clinical score + CR + BNP > 400 pg/mL (AUC 0.62), and clinical score + CR + BNP > 1000 pg/mL (AUC 0.66). Conclusion: Physical examination, CR and BNP had a poor performance in predicting a LAP ≥ 15 mm Hg. Using these parameters alone or in combination may lead to inaccurate estimation of hemodynamics.
