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.

Optimizing genomic DNA extraction from long-term preserved formalin-fixed and paraffin-embedded lung cancer and lymph node tissues.

Personalized therapy in lung cancer (LC) has revolutionized routine histopathology and cytopathology, emphasizing the importance of obtaining adequate material for molecular studies to support oncological decisions. Adaptations of cytologic sample preparations offer benefits for molecular testing, yet their potential remains underutilized. A significant number of LC cases is identified through specimens of aspiration or exfoliative cytology.
