Surgical multicenter collaborative studies: ¿What happen in Latin America?

Background: GlobalSurg is an international group of researchers whose purpose is to conduct and disseminate robust collaborative, international and multicenter studies.

Objective: To expose the necessary strategies and the barriers crossed in conducting massive multicenter studies in surgery.

Method: During the second semester of 2020, the study Surg-Week Prospective International Cohort Study was carried out.

Perioperative and anesthesia-related cardiac arrest and mortality rates in Brazil: A systematic review and proportion meta-analysis.

Introduction: Studies have shown that both perioperative and anesthesia-related cardiac arrest (CA) and mortality rates are much higher in developing countries than in developed countries. This review aimed to compare the rates of perioperative and anesthesia-related CA and mortality during 2 time periods in Brazil.

Methods: A systematic review with meta-analysis of full-text Brazilian observational studies was conducted by searching the Medline, EMBASE, LILACS and SciELO databases up to January 29, 2020.

High-Flow Nasal Cannula versus Continuous Positive Airway Pressure in Critical Bronchiolitis: A Randomized Controlled Pilot.

We conducted a randomized controlled pilot study in infants with critical bronchiolitis (  = 63) comparing high-flow nasal cannula (HFNC,  = 35) to continuous positive airway pressure (CPAP,  = 28). The primary outcome was treatment failure, defined as the need for bilevel positive pressure ventilation or endotracheal intubation. Treatment failure occurred in 10 patients (35.

Epidemiological and clinical features of imported malaria at the three main hospitals of the Friuli-Venezia Giulia Region, Italy.

Background: Imported malaria cases continue to occur in non-endemic regions among travellers returning from tropical and subtropical countries. At particular risk of acquiring malaria is the group of travellers identified as immigrants who return to their home country with the specific intent of visiting friends or relatives (VFRs) and who commonly believe they are immune to malaria and fail to seek pre-travel advice. Our aim was to review the current trends of imported malaria in the three main hospitals of the Friuli-Venezia Giulia region (FVG), North Eastern Italy, focusing in particular on patient characteristics and laboratory findings.

Cohesive silicone gel implants with smooth, textured or polyurethane-coated surface to restore volume in eviscerated sockets.

The purpose of this article is to evaluate the three different surface coating on cohesive silicone gel implants in eviscerated rabbit eye sockets. Forty-five albino rabbits underwent right eye evisceration and received hemisphere-shaped cohesive silicone gel implants with smooth (Group 1), textured (Group 2), or polyurethane-coated surface (Group 3) in the socket. The animals were euthanized at 7, 30, and 90 days postoperatively.
