Addressing the needs for cultural adaptation of DARE-keepin' it REAL among Brazilian students: strategies to improve implementation.

Subst Abuse Treat Prev Policy

December 2024

Department of Preventive Medicine, Universidade Federal de São Paulo, Rua Botucatu, N 740 - Vila Clementino, São Paulo, SP, 04023-062, Brazil.

Background: The widely implemented prevention program in Brazil, PROERD (a translated version of the DARE-kiR program), showed no evidence of effect in preventing drug use in a recent trial. The lack of cultural adaptation and instructors' deviations from the curriculum were identified as potential reasons for its ineffectiveness. This study aims to identify points of inadequacy of the PROERD program for the Brazilian culture, suggesting strategies for revising the curriculum to improve implementation.

The Influence of Ovarian-Derived Extracellular Vesicles in Reproduction.

Adv Anat Embryol Cell Biol

January 2025

Laboratory of Molecular Morphophysiology and Development, Department of Veterinary Medicine, School of Animal Science and Food Engineering, University of São Paulo, São Paulo, Brazil.

In this chapter, we explore the multifaceted roles of extracellular vesicles (EVs) in ovarian biology, focusing on their contributions to folliculogenesis, oocyte competence, corpus luteum function, and immune response regulation. EVs, particularly those derived from follicular fluid (ffEVs), are crucial mediators of cell-to-cell communication within the ovarian follicle, influencing processes such as meiotic progression, stress response, and hormonal regulation. We review preexisting literature, highlighting key findings on the molecular cargo of EVs, such as miRNAs and proteins, and their involvement in regulating the function of the follicle cells.

Objective: The relationship between different power equations and the severity of acute respiratory distress syndrome (ARDS) remains unclear. This study aimed to evaluate various power equations: total mechanical power, total elastic power (comprising elastic static and elastic dynamic power), and resistive power, in a cohort of mechanically ventilated patients with and without ARDS. Bayesian analysis was employed to refine estimates and quantify uncertainty by incorporating a priori distributions.

Background/aim: This study evaluated the diagnostic accuracy (DA) for colorectal adenomas (CRA), screened by fecal immunochemical test (FIT), using five artificial intelligence (AI) models: logistic regression (LR), support vector machine (SVM), neural network (NN), random forest (RF), and gradient boosting machine (GBM). These models were tested together with clinical features categorized as low-risk (lowR) and high-risk (highR).

Patients And Methods: The colorectal neoplasia (CRN) screening cohort of 5,090 patients included 222 CRA patients and 264 non-CRA patients.

Changes in blowfly (Diptera: Calliphoridae) wing morphology during succession in rat carcasses across forest and grassland habitats in South Brazil.

Insect Sci

December 2024

Programa de Pós-Graduação em Biodiversidade Animal, Departamento de Ecologia e Evolução, Universidade Federal de Santa Maria, Santa Maria, Brazil.

Succession is one of the most extensively studied ecological phenomena, yet debates persist about the importance of dispersal and external factors in driving this process. We aimed to quantify the influence of these factors by investigating how wing-related traits evolve across succession of blowfly (Diptera: Calliphoridae) communities in South Brazil. Rat carrion was placed in both forest and grassland habitats, and the associated blowfly communities were documented throughout the decomposition process.

Mindfulness interventions and quality of life in anxiety-related disorders: A systematic review and meta-analysis.

J Affect Disord

December 2024

Anxiety, Obsessions and Compulsions Research Program, Institute of Psychiatry, Federal University of Rio de Janeiro, Rio de Janeiro, Brazil; D'Or Institute for Research and Education, Rio de Janeiro, Brazil; Department of Psychiatry, School of Clinical Sciences, Monash University, Clayton, Victoria, Australia.

Mindfulness-based interventions (MBIs) effectively treat anxiety symptoms across different anxiety and related disorders (ARDs), including panic disorder, social anxiety disorder, generalized anxiety disorder, obsessive-compulsive disorder, and post-traumatic stress disorder. In this systematic review and meta-analysis, we investigate whether MBIs also lead to improvements in the quality of life (QoL) of patients with ARDs. A systematic review was performed through electronic search in PUBMED, PsycINFO, Embase, Web of Science, and Clinical Trials databases.

Orofacial pain is one of the most common causes of chronic pain leading to physical and cognitive disability. Several clinical and pre-clinical studies suggest that chronic pain results in cognitive impairment. However, there is a lack of meta-analyses examining the effects of orofacial pain models on behavioral learning and memory in rodents.

Although sperm sexing technology has progressed considerably in the last decade, there are still challenges to fully understand the reason for the low fertility of sexed sperm. Thus, we aimed to evaluate the effect of sexed and non-sexed sperm on the proteome of bovine oviduct epithelial cells (BOECs). Semen from six Nellore bulls was used and one ejaculate from each bull was collected and separated into three fractions: non-sexed, sexed for X-sperm and sexed for Y-sperm.

System justification, subjective well-being, and mental health symptoms in members of disadvantaged minority groups.

Clin Psychol Rev

December 2024

Department of Psychology, New York University, Meyer Building, 6 Washington Place, Room 530, New York, NY 10003, United States of America. Electronic address:

Although system justification-believing that the societal status quo is legitimate and desirable-is positively associated with subjective well-being and mental health outcomes for members of advantaged groups, the picture is more complicated for members of disadvantaged minority groups. According to system justification theory, believing that the social system is legitimate and desirable is a way of coping with one's own and fellow in-group members' state of disadvantage. At the same time, it is also a potential stressor, insofar as it implies that there are deficiencies of the individuals and groups who "fail" to succeed in a fair system.
