McGrath MAC Versus Three-Dimensional Printed Video Laryngoscopes: A Randomized, Manikin-Simulated Noninferiority Controlled Study with Medical Students.

Background: Proficiency in endotracheal intubation (ETI) is essential for medical professionals and its training should start at medical schools; however, large caseload may be required before achieving an acceptable success rate with direct laryngoscopy. Video laryngoscopy has proven to be an easier alternative for intubation with a faster learning curve, but its availability in medical training may be an issue due to its high market prices. We devised a low-cost 3-dimensionally printed video laryngoscope (3DVL) and performed a randomized trial to evaluate if the intubation success rate on the first attempt with this device is noninferior to a standard commercially available video laryngoscope (STVL).

Renal vein thrombosis in the course of non-operative treatment of kidney trauma: A rare case report.

Introduction: Venous thromboembolism is widely recognized as a life-threatening complication in trauma, yet renal vein thrombosis (RVT) following trauma is particularly rare.

Presentation Of Case: We report a case of a 67-year-old man who was brought to the emergency department after falling down a 14-step staircase at home which presented right kidney trauma (parenchyma laceration with a perirenal hematoma) on computed tomography, and hematuria. Considering the patient's hemodynamic stability, a non-operative treatment was initiated, and the patient was referred to the intensive care unit for close observation.

Effects of the COVID-19 pandemic on delays in diagnosis-to-treatment initiation for breast cancer in Brazil: a nationwide study.

Background: Short period from diagnosis to breast cancer (BC) treatment initiation remains challenging for the public health system in Brazil, which may have been further affected by the coronavirus disease-2019 (COVID-19) pandemic. This study assessed BC diagnosis-to-treatment intervals (DTi) in Brazil and the possible effects of the COVID-19 outbreak on delays.

Methods: The Painel de Monitoramento de Tratamento Oncológico database was queried to obtain the number of Brazilian patients with a BC confirmed diagnosis and initiating cancer treatment in the pre-COVID-19 (2013-2019) and during the COVID-19 (2020-2021) periods, adopting a 60-day limit as timely treatment.

Trends in the morbidity and mortality of coronavirus disease 2019 in different ethnic groups and gender in a large Brazilian city.

As the coronavirus disease 2019 (COVID-19) outbreak spread, evidence has emerged that gender and race would bear a disproportionate impact on the morbimortality of COVID-19. Here, we conducted a retrospective observational study using the TabNet/Departamento de informática do sistema único de saúde platform of the city of São Paulo. COVID-19 records from March 2020 through December 2021 were included, and we evaluated the temporal trends of confirmed cases and case fatality rate by gender and ethnicity.

A POPULATION STUDY ON GENDER AND ETHNICITY DIFFERENCES IN GALLBLADDER DISEASE IN BRAZIL.

Aim: Gallbladder diseases (GBD) are one of the most common medical conditions requiring surgical intervention, both electively and urgently. It is widely accepted that sex and ethnic characteristics mighty influence both prevalence and outcomes. This study aimed to evaluate the differences on distributions of gender and ethnicity related to the epidemiology of GBD in the Brazilian public health system.

Comparison of outcomes and cost-effectiveness of laparoscopic and open appendectomies in public health services.

Acute appendicitis is the leading cause of abdominal emergency surgery worldwide and appendectomy continues to be the definitive treatment of choice. This cost-effectiveness analysis evaluates laparoscopic versus open appendectomies performed in public health services in the state of Bahia (Brazil). We conducted a retrospective observational study using the database from the Department of Informatics of the Unified Health System (DATASUS).

Breast cancer in Brazil: Screening program and surgical approach.

Background: Screening mammography for breast cancer (BC) is a current strategy that reduces the mortality of BC by up to 30 %. Although mastectomy has been an important component of treatment for decades, conservative surgery (lumpectomy) has become the gold-standard approach for most cases, yet it depends on early detection of the BC.

Methods: This was an epidemiological study performed through DATASUS (2010-2018).

Undeclared civil war? Urban violence in major city in Brazil.

Purpose: Civil violence is responsible for 2.5% of deaths worldwide; it killed more people in the 21st century than the sum of all wars. This study describes violence victims treated at a trauma reference hospital in Salvador, Brazil and analyzes the impact of different types of interpersonal violence.

Pancreaticodudonectomy in trauma: One or two stages?

Introduction: Duodenopancreatic trauma is rare and presents high morbidity and mortality rates. Pancreaticoduodenectomy (PD) is the only possible treatment indicated for the most complex injuries (grades IV and V). Although, it is commonly a one-stage procedure, damage control surgery corroborates with a two-stage PD performed on unstable trauma victims.

Night admission is an independent risk factor for mortality in trauma patients - a systemic error approach.

Objective: to assess the impact of the shift inlet trauma patients, who underwent surgery, in-hospital mortality.

Methods: a retrospective observational cohort study from November 2011 to March 2012, with data collected through electronic medical records. The following variables were statistically analyzed: age, gender, city of origin, marital status, admission to the risk classification (based on the Manchester Protocol), degree of contamination, time / admission round, admission day and hospital outcome.

Common bile duct investigation in patients with mild biliary pancreatitis. when and how? A prospective analysis of 48 patients.

Background/aims: To define how and when patients with mild acute biliary pancreatitis must have their biliary tree investigated.

Methodology: We analyzed 48 patients' files with mild biliary pancreatitis between 1995 and 2004. After clinical treatment, magnetic resonance or endoscopic retrograde cholangiopancreatography and then surgery was performed.
