Cardiac Hemodynamics, Tissue Oxygenation, and Functional Capacity in Post-COVID-19 Patients.

: This study aimed to evaluate and compare the functional capacity of post-COVID-19 patients with a control group and analyze cardiac hemodynamics and muscle tissue oxygenation responses during assessment protocols in both groups. : A cross-sectional study was conducted involving patients with COVID-19 and a control group who were all aged ≥18 years. Participants underwent two functional capacity tests: the one-minute sit-stand test (1-STS) and the six-minute walk test (6MWT).

HEPATECTOMIES: INDICATIONS AND RESULTS FROM A REFERENCE HOSPITAL IN THE BRAZILIAN AMAZON.

Background: Hepatectomy is historically associated with higher morbidity and mortality, related to intraoperative blood loss and biliary fistulas. Technological advances and improvements in surgical and anesthetic techniques have led to greater safety in performing these surgeries.

Aims: The aim of this study was to analyze morbidity and mortality in patients undergoing hepatectomy.

Knowledge of the nursing team about cardiac arrest and cardiopulmonary resuscitation: mixed methods studies.

Objective: To analyze the knowledge and perceptions of the nursing team about arrest and cardiopulmonary resuscitation in adults before and after in situ simulation in emergency care.

Method: A sequential explanatory mixed methods study conducted in an Emergency Care Unit. Quantitative data were obtained through pre- and post-simulation questionnaire answered by 21 professionals and analyzed using descriptive and inferential statistics.

Docking heparan sulfate-based ligands as a promising inhibitor for SARS-CoV-2.

Context: Heparan sulfate (HS) linear polysaccharide glycosaminoglycan compound is linked to components from the cell surface and the extracellular matrix. HS mediates SARS-CoV-2 infection through spike protein binding to cell surface receptors and is required to bind ACE2, prompting the need for electronic structure and molecular docking evaluation of this core system to exploit this attachment in developing new derivatives. Therefore, we have studied five molecules based on HS using molecular docking and electronic structure analysis.
