This study found that finasteride significantly alters urinary steroid profiles, complicating the detection of steroid abuse in doping-control analysis by potentially causing false-negative results.

This study demonstrated that optical coherence tomography effectively detects significant changes in hair structure caused by steroid treatment, suggesting its potential use in doping control and clinical therapy monitoring.

This article reviews the legal processes for international athletes facing disciplinary actions and suggests enhanced legal representation and procedural changes to improve their access to justice, but reports no new results.

This study found that chronic administration of finasteride affected the isotopic composition of testosterone and nandrolone metabolites, impacting the drug-testing outcomes in athletic contexts.

This study found that corporate social responsibility can enhance consumer perceptions of product performance, especially when viewed as motivated by genuine benevolence rather than self-interest.

Real-life dosing of biologics for plaque psoriasis often deviates from recommended guidelines, especially for high-need patients.

This collection from the 2021 Manfred Donike Workshop outlines advancements in doping detection, highlighting new test methods and challenges, with a focus on steroidal substances, peptide hormones, and gene doping analysis.

In this study, conducted during the 22nd FIFA World Cup in Qatar, doping control analysis of 1612 samples showed negative results for prohibited substances, except for two instances each of codeine and carboxy finasteride.

This study found that female patients in Finnish specialized health care with a history of doping use exhibited high rates of psychiatric and substance use disorder morbidity, with less than half of those using anabolic androgenic steroids showing atypical red blood cell parameters.

This article provides contact details and affiliations for Amy M. Karch and Fred E. Karch; it presents no new research findings.

In this study, tofacitinib and baricitinib showed comparable efficacy and tolerability under unorthodox weight-stratified dosing in pediatric patients with moderate-to-severe alopecia areata over 24 weeks; however, the unorthodox baricitinib regimen yielded a lower effectiveness in severe cases, emphasizing the importance of adherence to guideline-recommended dosing.

This study found that tofacitinib and baricitinib, when administered with unorthodox weight-stratified dosing in pediatric patients with moderate-to-severe AA, showed comparable efficacy and tolerability, though baricitinib's efficacy decreased with non-standard dosing.

This study found that intralesional Diprospan injections and high-dose intravenous methylprednisolone may be effective for treating longstanding multifocal alopecia areata, with variable hair regrowth observed among patients.

This review discusses the use of anabolic-androgenic steroids in sports and outlines current methods for detecting urinary steroid doping, particularly testosterone, but reports no new experimental findings.

This article reviews the history and current medicolegal challenges of doping in sports, focusing on FIFA's procedures and three urgent legal issues, but presents no new findings.

In this study, the safety of finasteride in rats varied depending on dosing time, while its effectiveness on prostate weight reduction remained consistent.

The trial helped find the best dose of deuruxolitinib for treating alopecia areata.

This study reported the development of two highly sensitive ELISA assays to detect banned substances finasteride and dutasteride in human urine, offering better sensitivity than existing HPLC/MS/MS methods.

This article discusses the widespread issue of performance-enhancing drug use in sports, its health risks, and the importance of drug testing; it reports no new study findings.

This study investigated the metabolic pathways of epristeride, a new Type II 5α‐reductase inhibitor, using in vitro models and found that its metabolites show significant interactions with key proteins, suggesting implications for its role in doping control.

This study models the pathways of nandrolone and its metabolites in the body and suggests methods to counteract finasteride's role in enabling PED users to cheat drug tests.

This study observed significant inter- and intra-individual variability in serum testosterone levels among women treated with subcutaneous testosterone implants, suggesting that therapy should be guided by clinical response rather than single serum measurements.

This review reports that platelet-rich plasma may be more effective for musculoskeletal conditions when prepared with high platelet doses and low leukocyte content, but further trials are needed to confirm optimal formulations.

In this study of patients with androgenetic alopecia taking off-label low-dose oral minoxidil, adverse events like dizziness/lightheadedness, hypertrichosis, and extremity edema were observed in 14.9% of patients, with females experiencing more adverse events; higher doses increased dizziness risk, leading researchers to recommend cautious dosing approaches.

The study found that Tribulus terrestris extract, when administered in varying doses to C57BL/6J mice, may significantly increase MC-1R expression in hair follicle melanocytes.

This study found that monitoring endogenous steroid metabolites in serum may improve the detection of testosterone doping by highlighting promising biomarkers.

This correspondence reports the case of a young woman with severe lipid storage myopathy due to a rare mutation, who showed significant temporary improvement with plasmapheresis and immunoglobulin treatment before stabilizing with riboflavin and coenzyme Q10 supplementation, challenging the initial assumption of an immune-mediated condition.

This study observed that administering low-dose oral minoxidil during the daytime led to significantly greater hair density improvements in androgenetic alopecia patients compared to nighttime dosing. This suggests that circadian variations in hair follicle biology could be important for optimizing treatment outcomes.
