A portrait of germline pathogenic variants in high and moderate penetrance breast cancer genes in Brazil.

Introduction: The prevalence of germline pathogenic/likely pathogenic variants (P/LP) in high and moderate penetrance (HMP) genes is approximately 7%-10% among breast cancer (BC) patients. The prevalence and spectrum of BC P/LP variants are affected by several factors. There are limited genetic data from Brazilian patients with BC.

Recurrent Outbreak of Carbapenem-Resistant IMP-1-Producing Pseudomonas aeruginosa in Kidney Transplant Recipients: The Impact of Prolonged Patient Colonization.

Background: Infections by carbapenem-resistant Pseudomonas aeruginosa (CRPA) have been associated with high morbidity and mortality among solid organ recipients.

Objectives: To delineate the epidemiological and molecular characteristics of a recurrent outbreak of imipenem (IMP)-producing P. aeruginosa (CRPA) among kidney transplant (KT) recipient METHODS: We described a recurring CRPA outbreak in a KT ward, divided into two periods: before unit closure (Feb 2019-2020) and after reopening (Aug 2020-Dec 2023).

This in vitro study aimed to investigate the effect of plasma ion implantation nitriding on titanium's surface properties and initial cell response. Grade 4 titanium discs (12.7 × 2 mm) were blasted with aluminum oxide particles to create moderately rough surfaces.

Active surveillance versus immediate surgery in the management of low-risk papillary thyroid microcarcinoma: comparison of long-term costs in Brazil.

Objective: To compare the long-term medical costs of active surveillance (AS), partial thyroidectomy (PT), and total thyroidectomy (TT) in patients with low-risk papillary thyroid microcarcinoma (PTMC) receiving care covered by the Brazilian Public Health System.

Materials And Methods: After reviewing AS cohorts and our own data, we created a model of AS, PT, and TT flow care for low-risk PTMC over 10, 20, and 30 years. The medical costs included those associated with diagnosis, surgery, and follow-up.

Impact of a simple informative leaflet on Brazilian doctors' attitudes towards active surveillance of thyroid microcarcinomas.

Introduction: Active surveillance (AS) is increasingly recognized as an appropriate strategy for selected patients with papillary thyroid microcarcinomas (PTMC). However, some factors, including physician-related ones, hinder its widespread adoption.

Methods: To explore the prevailing barriers and the impact of information on attitudes towards AS implementation, we developed a questionnaire that was completed before and after reading a simple information leaflet by 317 doctors working in different work environments.
