Implementation of a Home-based Exercise Program for Cardiopulmonary Rehabilitation Patients during the SARS-CoV-2 Pandemic

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.

Athletes Health during Pandemic Times: Hospitalization Rates and Variables Related to COVID-19 Prevalence among Endurance Athletes

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.

Tratamento da classe III com mordida aberta anterior / The treatment of class III with anterior open bite – case report

O tratamento de classe III realizado no momento oportuno previne maiores discrepâncias na fase adulta. Este trabalho teve como objetivo demonstrar a efetividade do aparelho de Hyrax associado ao uso da máscara de Petit, em um relato de caso clínico. Paciente do sexo feminino, na fase do surto de crescimento puberal, apresentava classe III esquelética com atresia maxilar, mordida cruzada posterior e mordida aberta anterior. O tratamento proposto foi o uso do disjuntor de Hyrax associado ao uso da máscara facial de Petit. O tratamento se mostrou efetivo, colaborando para a melhora da relação das bases ósseas de classe III e correção da mordida aberta anterior...

The treatment of class III if done in the correct age can avoid major discrepancies in adulthood. This work aims to demonstrate the effectiveness of Hyrax associated with the use of the Petit's mask in a case report. Female patient in growth stage, skeletal class III with maxillary atresia, posterior cross bite and anterior open bite. The proposed treatment was the use of Hyrax and use of facial mask. This treatment demonstrated be effectively contributing to an improvement of the relationship of class III with the closure of the anterior open bite...
