Case report: Fatal long-term intoxication by 2,4-dinitrophenol and anabolic steroids in a young bodybuilder with muscle dysmorphia.

A case of chronic intoxication by 2,4-dinitrophenol (2,4-DNP) is reported in a 21-year-old bodybuilder, also known as an abuser of anabolic steroids, who died after ingesting 2 grams of this substance after 6 months of repeated consumption. The bodybuilder presented the triad of symptoms - tachycardia, tachypnoea, profuse sweating - from 6 months before his death, and was hospitalised for multiple organ failure 4 months before his death. Medical staff attributed this serious episode to his consumption of 2,4-DNP.

Non-Physiologic Doses of Androgenic Anabolic Steroids: Mortality and Underwriting Assessment.

Little evidence based information exists in the medical literature on the mortality of abusers of anabolic androgenic steroids. These individuals range from competitive athletes and body builders to those whose who use physician prescribed mega-doses. Life insurance medical directors have little guidance on how to underwrite these individuals when presented with their applications.

Anabolic steroids as the substrate for atrial fibrillation: a case report.

Background: Atrial fibrillation (AF) is the most frequently encountered sustained arrhythmia worldwide. This supraventricular rhythm disorder is precipitated by advanced age, valvular heart disease, hypertension, heart failure, congenital heart defects, and others. However, the role of anabolic steroids (ASs) abuse in precipitating AF remains insufficiently researched and largely underreported, despite their known cardiovascular risks.

Abuse of androgenic anabolic steroids (AAS) is associated with a range of cardiovascular side effects, summarized in this review. Apart from being linked to cardiovascular risk factors such as hypertension and dyslipidaemia, AAS abuse is associated with coronary atherosclerosis and imparts a pro-coagulative state, predisposing to thromboembolic disease. Finally, AAS abuse leads to left ventricular hypertrophy and dysfunction, which can ultimately result in heart failure.

Harm reduction techniques among cisgender gay, bisexual, and queer men using anabolic androgenic steroids: a qualitative study.

Background: Anabolic androgenic steroids (AAS) are synthetic forms of testosterone frequently used as performance enhancing drugs among gay, bisexual, and queer (GBQ) men. Despite widespread use, associated harms, and the likely existence of an AAS use disorder, there is no medical consensus on standards of care for people who use AAS, with most medical providers focusing exclusively on abstinence. Individuals using AAS have developed community-based harm reduction strategies to mitigate these harms.

Chronic high-dose testosterone disrupts social cognition and enhances social dominance in male long-Evans rats.

While increased aggression is the most consistent behavioral effect of anabolic androgenic steroid (AAS) abuse, its cause remains unclear. AAS may promote aggression by disrupting social behaviors which maintain dominance hierarchies. To model AAS abuse, we treated male rats with chronic high-dose testosterone and tested social recognition, social learning, and competitive and aggressive dominance.

A novel analytical strategy based on gas chromatography-Orbitrap high-resolution mass spectrometry combined with solid-phase extraction for the monitoring of stanozolol misuse in human urine.

Rationale: Stanozolol, an anabolic androgenic steroid listed in Part S1 of the World Anti-Doping Agency Prohibited List, exhibits a low response and significant matrix interference in urine samples when using liquid-liquid extraction-gas chromatography-mass spectrometry (GC-MS). Enhancing sample preparation techniques remains essential for the effective detection of stanozolol and its metabolites.

Methods: A method for determining stanozolol and its metabolites (3'-OH-stanozolol, 4β-OH-stanozolol, and 16β-OH-stanozolol) in human urine was developed and validated using GC-Orbitrap high-resolution MS combined with optimized mixed-mode solid-phase extraction (SPE).

New metabolites of methyltrienolone by in vitro human microsome and characterized using Liquid Chromatography/High Resolution Mass Spectrometry for doping control purposes.

Methyltrienolone (17β-hydroxy-17α-methylestra-4,9,11-trien-3-one) is one of the anabolic androgenic steroids (AAS) banned by the World Anti-Doping Agency (WADA). The biotransformation of methyltrienolone is performed in vitro by human hepatocytes microsomes. Both phase I and phase II experiments are investigated.

A study of long-term supraphysiologic-dose anabolic-androgenic steroid use on cognitive function in middle-aged men.

Long-term use of supraphysiologic doses of anabolic-androgenic steroids (AAS) has been associated with impaired visuospatial memory in young men but little is known about its cognitive effects in middle-aged men. We compared cognition in middle-aged men with histories of long-term AAS use and age-matched non-users. We administered cognitive tests from the CANTAB battery to 76 weightlifters aged 37-60 years (mean [SD] 48.

Exploring methandienone metabolites generated via homogenized camel liver: Advancements for anti-doping applications through High Resolution-Liquid Chromatography Mass Spectrometry analysis.

Rationale: Anabolic steroids, also known as anabolic-androgenic steroids (AAS), encompass steroidal androgens such as testosterone, as well as synthetic counterparts with similar structures and effects. The misuse of AAS has increased over the years, leading to ethical and welfare concerns in sports. The World Anti-Doping Agency (WADA) and the International Federation for Equestrian Sports (FEI) have banned AAS in relevant sports.

Persistent physiological benefits from doping? Ethical implications for sports integrity.

The effects of some widely abused doping substances such as anabolic androgenic steroids (AAS) on performance are well documented, particularly in the short term, and the use of these substances is banned by various sporting authorities, with athletes sanctioned from competing for up to 4 years. However, controversy exists on whether residual physiological effects of some doping practices could persist even years after discontinuation, granting unfair advantages to athletes long after sanctions have been served. Particularly, in support of the so-called muscle memory theory, growing evidence in both animals and humans suggests that AAS administration could exert long-term effects at the muscle level, notably a higher number of myonuclei.

A comprehensive gas chromatography electron ionization high resolution mass spectrometry study of a new steroidal selective androgen receptor modulator (SARM) compound S42.

The synthetic 20-keto-steroid S42 (1) demonstrated selective androgen receptor modulator (SARM) properties in preclinical studies and, consequently, received growing attention also in the context of sports drug testing programs. Fundamental understanding of the behavior of S42 (1) and of relevant derivatives in gas chromatography-electron ionization MS experiments at high resolution (GC-EI-HRMS) is indispensable to develop a reliable qualitative and quantitative doping control method for S42 (1) and its metabolites in body fluid matrices. We present important fundamental mechanistic data on the EI fragmentation behavior of S42 (1) and of silyl ether derivatives as well as of stable isotope-labelled reference material.
