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

J Bras Pneumol

January 2025

. Laboratório de Função Pulmonar, Instituto de Assistência ao Servidor Público Estadual de São Paulo Francisco Morato Pereira - IAMSPE-FMO - São Paulo (SP), Brasil.

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.

This study aimed to identify splicing quantitative trait loci (cis-sQTL) in Nelore cattle muscle tissue and explore the involvement of spliced genes (sGenes) in immune system-related biological processes. Genotypic data from 80 intact male Nelore cattle were obtained using SNP-Chip technology, while RNA-Seq analysis was performed to measure gene expression levels, enabling the integration of genomic and transcriptomic datasets. The normalized expression levels of spliced transcripts were associated with single nucleotide polymorphisms (SNPs) through an analysis of variance using an additive linear model with the MatrixEQTL package.

Compressed SENSE acceleration factor influence on magnetic resonance image quality in patients with endometrial cancer.

Phys Med

January 2025

Center for Radiology, University Clinical Center of Vojvodina, Hajduk Veljkova 1-9, 21000 Novi Sad, Serbia; Faculty of Sciences, University of Novi Sad, Trg Dositeja Obradovića 3, 21000 Novi Sad, Serbia. Electronic address:

Objectives: To investigate the impact of compressed sensing - sensitivity encoding (CS-SENSE) acceleration factor on the diagnostic performance of magnetic resonance imaging (MRI) within standard female pelvis protocol in patients with endometrial cancer.

Methods: T2-weighted turbo spin echo (TSE) sequence from standard female pelvic MRI protocol was chosen due to its long acquisition time and essential role in the evaluation of morphological characteristics of the female pelvic anatomical structures. Fully sampled reference scans and multiple prospectively 2x to 5x under-sampled CS-SENSE scans were acquired.

Why are we not exploring the potential of lower limb muscle power to identify people with sarcopenia?

Ageing Res Rev

January 2025

Fondazione Policlinico Universitario Agostino Gemelli, IRCCS, Rome, Italy; Department of Geriatrics and Orthopedics, Università Cattolica del Sacro Cuore, Rome, Italy. Electronic address:

Sarcopenia refers to a neuromuscular disease characterized by age-related declines in muscle mass and function. Since Professor Rosenberg first introduced the concept of sarcopenia in 1989, numerous operational paradigms have been proposed, tested, and validated against negative outcomes. The most recent recommendations advocate that dynapenia, or reduced of muscle strength, should be used alongside low muscle mass for the identification of sarcopenia.

Purpose: Resting beat-to-beat blood pressure variability is a strong predictor of cardiovascular events and mortality. However, its underlying mechanisms remain incompletely understood. Given that the sympathetic nervous system plays a pivotal role in cardiovascular regulation, we hypothesized that alpha-1 adrenergic receptors (the main sympathetic receptor controlling peripheral vasoconstriction) may contribute to resting beat-to-beat blood pressure variability.

DNA metabarcoding reveal hidden diversity of periphytic eukaryotes on marine Antarctic macroalgae.

An Acad Bras Cienc

January 2025

Universidade Federal de Minas Gerais, Instituto de Ciências Biológicas, Departamento de Microbiologia, Av. Antônio Carlos, 6627, Pampulha, 31270-000 Belo Horizonte, MG, Brazil.

Polar marine macroalgae thrive in extreme conditions, often displaying geographic isolation and high degree of endemism. The "phycosphere" refers to the zone around the algae inhabited by microrganisms. Our study used DNA metabarcoding to survey the eukaryotic communities associated with seven seaweed species obtained at King George Island (South Shetland Islands, maritime Antarctic), including two Rhodophyta, two Chlorophyta and three Phaeophyceae.

January 2025

Universidade de Brasília, Laboratório de Criptógamas, Departamento de Botânica, Campus Universitário Darcy Ribeiro, Bloco D, 1° Andar, 70910-900 Brasília, DF, Brazil.

The exploration of extraterrestrial environments has become a focal point of scientific inquiry, driven by advancements in technology and a growing interest in the potential for life beyond Earth. This study investigates the adaptability of Antarctic nematodes, known for thriving in extreme cold and isolation, to simulated Martian (MGS-1) and Lunar (LMS-1) soils. The experiment revealed differential responses in nematode survivability to the two simulants, with Lunar soil demonstrating better adaptability compared to Martian soil.

Removal of the buccal fat pad can be considered safe as long as there is a detailed analysis of anatomical landmarks. The objective of this study was to estimate the prevalence of intra- and postoperative complications resulting from buccal fat pad removal through a systematic review. The search strategy involved observational and/or interventional studies in humans that included at least one case of buccal fat pad removal with a description of the surgery, postoperative progress, and complications.

Temporomandibular disorders (TMD) usually affect the stomatognathic system and can be symptomatic. Patients often self-medicate to relieve symptoms, and this can increase the risk of complications such as adverse drug reactions, overdose, physical and psychological dependence, and delay of appropriate treatment. It is important for dentists to know the prevalence of self-medication to investigate this condition in their patients, thus the primary aim of this study was to estimate the prevalence of self-medication among university students with no TMD, non-painful TMD and painful TMD and the secondary aim was to assess association with independent factors.

Promoting child well-being and development requires a multidimensional approach, including the right to adequate food practices. Socially vulnerable children are more exposed to adverse experiences, such as inadequate food consumption due to poverty. In this context, home-visiting programs are an important strategy for nutritional and health care education to provide relevant guidelines.

Although androgenic alopecia is the most prevalent among non-cicatricial alopecia, it still lacks an effective and safe treatment. Dutasteride (DUT) shows promising results in hair regrowth; however, oral DUT intake causes serious sexual adverse events. Hence, we produced liposomes with different bilayer structures and evaluated the capability of such systems in increasing DUT accumulation in the hair follicles.
