This study found that long-term total parenteral nutrition in pediatric patients led to severe zinc deficiency, which improved with intravenous zinc therapy, highlighting the need for adequate zinc inclusion in nutritional solutions.

This source reports that while creatine supplementation is popular for improving muscle mass and performance, questions about its efficacy and safety persist. An expert team is reviewing literature to address concerns like water retention, renal effects, and its benefits across different populations and uses.

This case study potentially links the use of anabolic steroids to increased severity of COVID-19 in a healthy 28-year-old man, with marked symptom improvement following treatment with proxalutamide.

This study observed that integrating best practices for anabolic androgenic steroid users into Swiss primary care is feasible and well-accepted, though current doping laws hinder adequate medical care for this population.

In this study, researchers found that taking Saw palmetto and Pygeum africana supplements for five days altered the urinary steroid profile in a way that may interfere with the steroidal module of the Athlete Biological Passport.

This study provides a comprehensive analysis of anabolic-androgenic steroids, reporting that their use enhances muscle mass but is associated with significant health issues including cardiac muscle hypertrophy, liver disease, and changes in gender characteristics, emphasizing the need for patient awareness of these risks.

This review outlines the major health consequences of anabolic-androgenic steroid abuse, with a focus on sexual and reproductive issues, and suggests management prioritizes cessation and relapse prevention due to lack of robust randomized trials.

This review found that hormones significantly impact women's health and athletic performance, influencing the menstrual cycle, menopause, and exercise responses, while therapies like contraception and hormone replacement require personalized approaches to balance benefits and risks.

Nandrolone and oxandrolone could help treat male health issues like muscle loss and low testosterone.

This review found no evidence that DHEA improves quality of life or decreases menopausal symptoms in peri- and postmenopausal women, but it may slightly enhance sexual function compared to placebo.

This paper proposes a theory explaining how the normal anabolic effects of androgens lead to structural changes and hair follicle miniaturization, contributing to androgenic alopecia.

This study identified new oxidative derivatives of finasteride, including a newly discovered metabolite, by using the fungus Macrophomina phaseolina.

This study identified proteins that are differentially expressed in balding versus non-balding dermal papilla cells, potentially aiding the understanding and treatment of androgenetic alopecia.

The document explains different hair and scalp conditions, including common hair loss after pregnancy or illness, drug-induced hair loss, hereditary excessive hair growth, patterned baldness, autoimmune hair loss, and permanent loss due to skin disease, with generally limited treatment options.

This report presents a case where female pattern hair loss might be linked to tamoxifen use, with increased androgen receptor expression observed in the affected scalp area.

This study found that a significant portion of counterfeit drugs seized among bodybuilders did not match their labels, with many containing undeclared anabolic steroids or other unexpected active ingredients.

This article discusses the potential effects of exogenous testosterone, highlighting that its impact on prostate cancer progression, cardiovascular health, and behavior remains uncertain and needs further investigation.

This review discusses hormones that affect acne and highlights a statistically significant link between a low-glycemic-load diet and reduced acne activity, but reports no new experimental findings.

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.

Hair loss that spreads out can often fix itself or be treated by finding and handling the cause.

This study observed that eliminating positional error in hair segment analysis can improve understanding of changes in isotopic composition, aiding the identification of pathological conditions and dietary patterns.

This review discusses the potential carcinogenic effects of anabolic androgenic steroids, particularly regarding Leydig cell tumors, and highlights the need for preventive information campaigns due to associated health risks.

This review discusses various drugs that can cause drug-induced acne, noting specific clinical and histopathologic features, but reports no new clinical findings.

In this animal study, administering testosterone alongside a 5α-reductase inhibitor counteracted testosterone's effects on prostate enlargement while preserving its beneficial effects on muscle and bone.

This study found that human scalp hair follicles can internally operate a Cori cycle, synthesize glycogen in the presence of lactate, and modulate growth through glycogen phosphorylase activity.

This review discusses the relevance of human androgen receptor action in sports doping and examines the potential of cell-based biological assays for detecting androgenic anabolic steroid use, without presenting new research findings.

This study reported the development of a novel and reliable liquid chromatographic method to measure testosterone and epitestosterone in human urine, offering sensitive detection for doping control.

This review examines the negative effects of anabolic-androgenic steroid use on the male reproductive system, including impaired testosterone production, sperm production issues, and adverse metabolic consequences without reporting new clinical results.

This review highlights the potential therapeutic applications of nandrolone, an anabolic steroid, for male health, but notes that more human studies are needed due to limited existing literature.

This review discusses "follicular hypoglycania" as a potential pathology in hair growth disorders and reports that proteoglycan replacement therapy may improve hair loss treatments, though it presents no new clinical trial results.
