Multicenter StudyPrevalence of COVID-19 in medical school and residency in Porto Alegre, RS.
A multicentric, cross-sectional study was carried out to determine the prevalence and risk factors for Coronavirus disease 2019 in medical students and residents from four universities and affiliated hospitals in Brazil. ⋯ Medical students, interns, and residents have a higher prevalence of Coronavirus disease 2019 than the general population, in which the last two groups are significantly at higher risk. Contacting patients at a higher weekly frequency increases the risk for infection. The use of goggles should be reinforced when contacting patients.

Secondary bacterial infections in patients with coronavirus disease 2019-associated pneumonia.
The vast majority of patients who hospitalized with coronavirus disease 2019 are given empirical antibiotic therapy. However, information on the frequency, microorganism species, and resistance rates of secondary bacterial infections in coronavirus disease 2019 patients are insufficient. We aimed to show the frequency of secondary infections and resistance conditions in patients with coronavirus disease 2019 hospitalized in the intensive care unit. ⋯ We think that our study can be useful in choosing empirical antibiotic therapy in the coronavirus disease 2019 pandemic and reducing the mortality that may occur with secondary infection.

Cardiovascular drugs and analysis of potential risk factors associated with mortality in severe coronavirus disease 2019 patients.
Cardiovascular diseases are also considered to increase the risk of death in COVID-19 patients. However, real-world data concerning the risk factors for death in patients with severe COVID-19 still remain vague. This study aimed to identify the potential risk factors associated with mortality in severe COVID-19 patients. ⋯ This study failed to demonstrate a significant difference in preexisting cardiovascular diseases and cardiovascular medications between survivors and nonsurvivors who were admitted to ICU for severe COVID-19. Our findings indicate that the presence of chronic renal failure, a high peak ferritin concentration, and the need for invasive mechanical ventilation appear predictive for mortality. We propose that these risk factors should be taken into account in defining the risk status of severe COVID-19 patients admitted to the ICU.

Observational StudyDrug utilization study in neonatal intensive care unit at tertiary care hospital.
Neonates are more susceptible to drug interactions and adverse effects, and special care should be taken when prescribing medication to them. This study aimed to investigate drug usage in the neonatal intensive care unit of a tertiary care hospital. ⋯ Premature birth and resulting low birth weight were the main reasons for drug prescription. High administration of antibiotics is probably an area of concern and should be seriously considered.

Effect of meteorological factors on first episode and recurrence of primary spontaneous pneumothorax.
In this study, we evaluated the clinical characteristics and seasonal distribution of patients with primary spontaneous pneumothorax and examined the relationships between meteorological factors and pneumothorax development overall and in terms of first episode and recurrence. ⋯ Our results indicated that meteorological factors (i.e., atmospheric pressure, humidity, wind speed, temperature, and precipitation) were not associated with pneumothorax development. By comparing the patients with first episode and recurrence, the humidity was significantly lower in the recurrence group.
