New spirometry recommendations from the Brazilian Thoracic Association - 2024 update.

The latest pulmonary function guideline from the Brazilian Thoracic Association was published in 2002, since which there have been updates to international guidelines (mainly those from the European Respiratory Society and the American Thoracic Society), as well as new national and international publications on various aspects of the performance, interpretation, and clinical implications of spirometry. Despite those updates, a careful analysis of what applies to the reality in Brazil is essential, because there have been studies that evaluated individuals who are representative of our population and who could show responses different from those of individuals in other regions of the world. This document is the result of the work of a group of specialists in pulmonary function who evaluated relevant scientific articles that could be applicable to the population of Brazil.

Quality of Life and Adaptation of People With a Colostomy Plug: A Before-After Interventional Study.

Purpose: The purpose of this study was to examine health-related quality of life and adaptation of persons with a colostomy before and after use of a colostomy plug.

Design: Single group before-and-after study.

Subjects And Setting: The study sample comprised 19 people with a colostomy who attended an outpatient clinic João Pessoa, in Paraiba, Brazil.

Assessment of cfDNA release dynamics during colorectal cancer surgery.

Approximately two-thirds of patients with colorectal cancer (CRC) undergo resection with curative intent; however, 30% to 50% of these patients experience recurrence. The concentration of cell-free DNA (cfDNA) before and after surgery may be related to the prognosis of patients with CRC, but there is limited information regarding cfDNA levels at the time of surgery. Here, we analyzed surgical cfDNA release using plasma samples from 30 colorectal cancer patients at three key points during surgery: preoperative (immediately before surgery), intraoperative (during surgery), and postoperative (at the end of surgery).

Utility of the radiological report function of an artificial intelligence system in interpreting CBCT images: a technical report.

Objectives: The aim of this technical report was to assess whether the "Radiological Report" tool within the Artificial Intelligence (AI) software Diagnocat can achieve a satisfactory level of performance comparable to that of experienced dentomaxillofacial radiologists in interpreting cone-beam CT scans.

Methods: Ten cone-beam CT scans were carefully selected and analyzed using the AI tool, and they were also evaluated by two dentomaxillofacial radiologists. Observations related to tooth numeration, alterations in dental crowns, roots, and periodontal tissues were documented and subsequently compared to the AI findings.

Hyperuricemia Is Associated With Higher Mortality in Non-diabetic Heart Failure Patients.

Introduction: Hyperuricemia (HU) is associated with an increased risk of incident heart failure (HF) and adverse HF outcomes. Patients with diabetes mellitus (DM) have a greater prevalence of HU.

Aims: We evaluated the prognostic impact of HU in patients with HF according to the coexistence of DM.
