Impact of the COVID-19 Pandemic on the Outcomes of Patients Undergoing Oncological Surgeries: CORONAL Study.

Background: The impact of coronavirus disease 2019 (COVID-19) on postoperative recovery from oncology surgeries should be understood for the clinical decision-making. Therefore, this study was designed to evaluate the postoperative cumulative 28-day mortality and the morbidity of surgical oncology patients during the COVID-19 pandemic.

Methods: This retrospective cohort study included patients consecutively admitted to intensive care units (ICU) of three centres for postoperative care of oncologic surgeries between March to June 2019 (first phase) and March to June 2020 (second phase).

Stress and substance abuse among workers during the COVID-19 pandemic in an intensive care unit: A cross-sectional study.

Objective: Professionals working in intensive care units (ICUs) during the COVID-19 pandemic have been exposed to stressful situations and increased workload. The association between symptoms of traumatic stress disorders, substance abuse and personal/occupational characteristics of Brazilian COVID-19-ICU workers is still to be addressed. Our aim was to evaluate the prevalence of those conditions and to find if those associations exist.

[Evaluation of the cold chain for vaccine conservation in primary healthcare centers in the South and Midwest regions of São Paulo city, Brazil, in 2011-2012].

Objective: to assess the cold chain capacity, health workers' immunobiological product conservation knowledge and practices in Primary Healthcare Centers (PHC) in São Paulo city, Brazil.

Methods: this descriptive study included 24 randomly selected PHC in the South and Midwest regions of the city; between December 2011 and July 2012, we interviewed the health workers on their vaccine conservation knowledge/practice and observed the local infrastructure, using a form developed for this project; we assigned points to items of the form and classified each PHC as sufficient, regular or insufficient.

Results: most of the 24 PHC evaluated were administered by Social Organizations; all of them had vaccine storage chambers; 5 PHC reported using their maximum storage capacity; 9 PHC were classified as having sufficient knowledge/practice and 15 as having regular knowledge/practice.
