The selection and expression of conspicuous colorations in animals is often related to anti-predation strategies and sociosexual communication. The giant river prawn, Macrobrachium rosenbergii (de Man, 1879) is a species with three male morphotypes that vary in claws' coloration and the size of the animals. It has been suggested that male reproductive quality might be associated to their coloration, but evidence is still conflicting.

Introduction: Sarcopenia and Osteoporosis are two prevalent conditions in the older population and are defined by low strength, muscle quality/volume and low Bone Mineral Density, respectively. When there is a concomitant presence of both, there is a novel musculoskeletal condition called Osteosarcopenia. These conditions adversely affect quality of life and elevate the risk of fractures, disability, and mortality among older individuals.

Parmigiano Reggiano protected designation of origin (PDO) cheese inherently exhibits variability due to the characteristics of the production system, contributing to heterogeneity in the composition and properties of milk used in the cheese-making process. This variability leads to variations in cheese yield and nutrient recoveries. The direct measurement of these traits is not feasible in routine practice.

Food insecurity violates the right to regular access to quality food, affecting population groups unequally. In Brazil, FI is associated with both malnutrition and increased obesity and is intertwined with racial and gender inequalities, perpetuating cycles of poverty and social exclusion. This protocol aims to select observational studies that evaluate the association between food insecurity and overweight and their intersectional discussions (gender and race/color).

Pediatr Pulmonol

December 2024

Postgraduate Program in Communication Disorders, Center for Advanced Studies in Systematic Review and Meta-Analysis - NARSM, Tuiuti University of Paraná, Curitiba, Paraná, Brazil.

Objective: This study aims to determine the prevalence of oropharyngeal dysphagia (OD) in children, as diagnosed through instrumental evaluation, and to identify associated risk factors.

Methods: A systematic search was conducted across six databases (Embase, LILACS, LIVIVO, PubMed/MEDLINE, Scopus, and Web of Science), as well as gray literature sources (ASHA, Google Scholar, and ProQuest). Studies involving children (under 12 years of age), diagnosed using instrumental methods such as videofluoroscopic swallow study (VFSS) or fiberoptic endoscopic evaluation of swallowing (FEES), were included.

Introduction: Although noninvasive monitoring through quantifying rib cage movement has been useful in serial assessment of pulmonary function in newborns, measuring tidal volume (TV) is commonly performed invasively. As it is the most basic measure of pulmonary function, expanding its assessment to a noninvasive measure can contribute to clinical findings and interpretations in neonatal clinical practice.

Objective: (1) Create a noninvasive measurement tool for TV for neonatal clinical use; (2) Evaluate the agreement between measured TV and predicted TV.

Thin films of chalcopyrite, CuFeS, are promising candidates for use as absorber layers in photovoltaic cells due to their low band gap and high absorbance. These films are typically deposited in two or three steps, always involving an annealing process. In this work, the CuFeS film was deposited on a glass substrate in a single deposition step using the cathodic cylindrical plasma deposition (CCyPD) technique.

Background: In recent years, there has been a significant focus on exploring the potential therapeutic impact of altered states of consciousness on treatment outcomes for mental illness, with the goal of enhancing therapeutic strategies and patient results.

Methods: This meta-analysis was designed to investigate the potential link between the psychomimetic effects of ketamine and clinical outcomes in mental health, which adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Results: Eleven studies were selected for meta-analysis, and the main result did not find a significant correlation between the psychoactive effects of ketamine and clinical outcomes either in mental illness (n = 11; n's = 27; r = 0.

Article Synopsis
  • The study focuses on comparing methods for normalizing electromyographic signals from respiratory muscles in both healthy individuals and those with Amyotrophic Lateral Sclerosis (ALS).
  • 67 subjects (50 healthy and 17 with ALS) were analyzed during various breathing maneuvers to measure muscle activity.
  • The results indicated that for healthy individuals, maximal voluntary isometric contraction (MVIC) was the best method for assessing inspiratory muscle activity, while in ALS patients, the maximum nasal inspiratory pressure (SNIP) maneuver was more effective for inspiratory muscle normalization.

Electronic address:

Small-scale fisheries, especially those from developing countries, are vital for millions. Understanding the impact of environmental and human factors on fish stocks and yields and how they might change is crucial to ensure the sustainable use of aquatic resources. We developed an ecosystem model using Ecopath and Ecosim (EwE) to investigate changes in target species biomass and ecosystem attributes over 83 years (2017-2100) caused by different scenarios of fishing pressure and ocean warming in the Brazilian Northeastern continental shelf.
