Purpose: Combat sports, such as judo, are weight categorized. Weight control was established to promote fair disputes among individuals. However, combat sports athletes adopt rapid weight loss (RWL) to obtain an advantage over smaller and lighter opponents. This scoping review article presents the prevalence, magnitude, and methods of RWL and its effects on physical and competitive performance, health risks, and psychological effects. Specific recommendations for attenuating the effects of RWL are also presented.
Methods: Studies were retrieved from Web of Science, PubMed, and Scopus databases. Four hundred and forty-six articles were identified, of which fifty-three were considered eligible for this review.
Results: The results showed that the prevalence of RWL was between 40% and 92.9% and that athletes reduced their body mass by approximately 5%. Although the literature suggests that RWL impairs the performance and psychological well-being of athletes, these results were obtained when recovery time was not provided.
Conclusion: No negative effects on performance were observed when the recovery time was >4 h. However, health risks due to RWL practices should be considered, and RWL should be avoided.

Background: Exosomes are nanoscale vesicles derived from various cell types and tissues that have many potential applications, generating great interest from researchers. One particularly intriguing application of exosomes is their use as a direct therapeutic for aesthetic indications. Several studies and case reports have explored the impact of exosomes for numerous cosmetic concerns but a consensus on the outcomes of these studies has not been established.

Study Question: How accurately can artificial intelligence (AI) models predict sperm retrieval in non-obstructive azoospermia (NOA) patients undergoing micro-testicular sperm extraction (m-TESE) surgery?
Summary Answer: AI predictive models hold significant promise in predicting successful sperm retrieval in NOA patients undergoing m-TESE, although limitations regarding variability of study designs, small sample sizes, and a lack of validation studies restrict the overall generalizability of studies in this area.
What Is Known Already: Previous studies have explored various predictors of successful sperm retrieval in m-TESE, including clinical and hormonal factors. However, no consistent predictive model has yet been established.

Distal fibula fractures involving the ankle are one of the most common fractures, often requiring open reduction and internal fixation with plates and screws. The increased incidence of potential wound complications arising from open reduction methods led to a rejuvenated interest in the application of minimally invasive methods like intramedullary nailing of the fibula in the management of ankle fractures and isolated distal fibular fractures. A literature search was performed using Medline, Cochrane, and Embase from 1993 to 2023.

Materials And Methods: We searched Ovid and other databases for studies on sex differences and cognitive decline, focusing on publications in peer-reviewed informatics journals and conference proceedings from 2000 to 2023. The selected manuscripts were analyzed and summarized through discussion among three reviewers.

Stigma and discrimination-based narratives have been associated with adverse health outcomes. Migrants and refugees face multiple barriers to accessing healthcare, influenced by stigma and discrimination-based narratives against them. We conducted a scoping review of scientific and grey literature (n = 61) to discuss available evidence in Latin America and the Caribbean (LAC) concerning communication and narrative speeches related to international migration and its implications for population health, particularly when associated with stigma and discrimination against migrants and refugees.
