Abstract
Ostarine is the most popular compound in the selective androgen receptor modulator group (SARMs). Ostarine is used as a physical performance-enhancing agent. The abuse of this agent in higher doses may lead to severe side effects. Here, we evaluate the effects of ostarine on the heart. We utilized a cardiomyocyte H9C2 cell line, isolated primary female and male cardiac fibroblast cells, as well as hearts obtained from rats. Ostarine increased the accumulation of two fibrosis protein markers, αSMA and fibronectin (p < 00.1) in male, but not in female fibroblast cells. Ostarine increased the expression of the cardiomyopathy marker βMhc in the H9C2 cell line (p < 0.05) and in the heart in rats (p < 0.01). The unfavorable changes were observed at high ostarine doses. Moreover, a decrease in viability and an increase in cytotoxicity marker LDH were observed already at lowest dose (1 nmoL/l). Taken together, our results suggest that ostarine is cardiotoxic which may be more relevant in males than in females.

Tibúrcio FC, Leite APS, Muller KS, Pinto CG, Valentino E, Castro PATDS, Matsumura CY, de Carvalho SF, Matheus SMM. Effects of Nandrolone Decanoate on Skeletal Muscle and Neuromuscular Junction of Sedentary and Exercised Rats. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1940. [PMID: 38003989 PMCID: PMC10673219 DOI: 10.3390/medicina59111940] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 10/03/2023] [Accepted: 10/23/2023] [Indexed: 11/26/2023]
Abstract
Background and Objectives: Nandrolone decanoate (ND) is the most widely used among the anabolic androgenic steroids (AAS), synthetic substances derived from testosterone, to improve muscular and health gains associated with exercises. The AAS leads to physical performance enhancement and presents anti-aging properties, but its abuse is associated with several adverse effects. Supraphysiological doses of AAS with or without physical exercise can cause morphological and functional alterations in neuromuscular interactions. This study aims to investigate the effects of ND supraphysiological doses in neuromuscular interactions, focusing on the soleus muscle and its neuromuscular junctions (NMJs) in rats, associated or not with physical exercise. Materials and Methods: Forty male Sprague Dawley rats were divided into four groups: sedentary and exercised groups, with or without ND at the dose of 10 mg/kg/week. The animals were treated for eight weeks, with intramuscular injections, and the soleus muscle was collected for morphological analyses. Results: The supraphysiological doses of ND in the sedentary group caused muscle degeneration, evidenced by splitting fibers, clusters of small fibers, irregular myofibrils, altered sarcomeres, an increase in collagen deposition and in the number of type I muscle fibers (slow-twitch) and central nuclei, as well as a decrease in fibers with peripheral nuclei. On the other hand, in the ND exercise group, there was an increase in the NMJs diameter with scattering of its acetylcholine receptors, although no major morphological changes were found in the skeletal muscle. Thus, the alterations caused by ND in sedentary rats were partially reversed by physical exercise. Conclusions: The supraphysiological ND exposure in the sedentary rats promoted an increase in muscle oxidative pattern and adverse morphological alterations in skeletal muscle, resulting from damage or post-injury regeneration. In the ND-exercised rats, no major morphological changes were found. Thus, the physical exercise partially reversed the alterations caused by ND in sedentary rats.

Abstract
Anabolic androgenic steroids (AASs) are synthetic analogs of testosterone that can affect the immune system. Bodybuilders and sportsmen are at risk of abusing AASs. The aim of this study was to investigate the association between AASs use and coronavirus disease (COVID-19). This cross-sectional study included adults aged 18 years and above. Between 16 April and 23 June 2021, gym-attending participants completed an online survey. Multivariable analysis was performed using multiple logistic regression to identify factors associated with COVID-19 diagnosis and severity. Current use of AASs was reported in 7.5% of the 520 study participants. Approximately 20% of the study participants reported that they had contracted COVID-19, approximately half of whom reported moderate to severe disease. Contracting COVID-19 was reported more frequently by current users than by non-current users (35.90% vs. 18.92%, p = 0.011). Multivariable analysis revealed that contracting COVID-19 was nearly five times more likely among current users of AASs than among non-current users (OR = 4.89, 95% CI: 1.69–14.13). Current use of AASs was also associated with greater odds of moderate to severe COVID-19 disease (OR = 3.71, 95% CI: 1.04–13.21). Our findings suggest that the use of AASs could be an underlying risk factor for COVID-19 severity.

Abstract
Misuse of anabolic-androgenic steroids (AAS) to boost performance and appearance is rising in the United States (US) with approximately one million people experiencing dependence. Long-term AAS misuse can lead to cardiovascular pathology but rarely cardiogenic shock. We report the case of an acute ischemic stroke secondary to an intracardiac thrombus in a patient with biventricular failure and cardiogenic shock associated with AAS misuse. Discontinuation of AAS and institution of guideline-directed medical therapy might reverse AAS-related heart failure.

Abstract
Background: Anabolic androgen steroid (AS) use has adverse effects on left ventricular functions, such as fibrosis development. Fragmented QRS is an important marker of myocardial fibrosis, while speckle-tracking echocardiographyis a method used to show subclinical left ventricle dysfunction. In this study, we examined the the ability of fQRS + to detect left ventricle fibrosis by speckle tracking echocardiography (STE) in AS users.Methods: The study included a total of 181 healthy athletes. Athletes were divided into two groups as AS users (n = 89) and non-AS users (n = 92). Then, athletes using AS were divided into two groups as fQRS+ (n = 52) and fQRS- (n = 37). In both groups, the arithmetic mean of three images was used to obtain the left ventricle global longitudinal strain (LV-GLS). The E/SRe ratio was also calculated and analysed.Results: There were significant differences between the AS users and non-AS users in terms of, E/SRe (55.7 ± 17.9 vs 50.3 ± 14.8; p = 0.015), LV-GLS (23.1 ± 1.9 vs 24.0 ± 1.7; p = 0.001), and fQRS (18.5% vs 6%; p = 0.005). When subgroup analysis was performed, both LV-GLS and E/SRivr were found to be poor in the fQRS + group. When multiple linear regression analysis was performed, we determined fQRS as an independent predictor for LV-GLS and E/SRivr ratio.Conclusion: In conclusion, our study demonstrated that fQRS is a parameter that can beused to determine left ventricle subclinical systolic and diastolic dysfunction in AS users. It can be used for cessation of drug use, especially in long-term use.

Abstract
The purpose of this study is to histologically and immunohistochemically determine the changes created by grayanotoxin-III (GTX-III), which is a sodium channel neurotoxin, on heart tissues in different dosages. Rats were randomly divided into 10 groups to determine the acute and chronic effects of GTX-III. While the rats in groups 1 and 6 were control rats, the rats in groups 2–5 (1, 2, 4, and 8 μg/kg bw GTX-III) received a single dose of intraperitoneal GTX-III, and the rats in groups 7–10 received GTX-III every day for 3 weeks. As a result of the trial, in the heart tissues, histopathological changes were determined by hematoxylin–eosin staining, interleukin-1 (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and brain natriuretic peptide (BNP) were determined by the avidin–biotin peroxidase method, and apoptosis was examined by immunohistochemistry (IHC) analysis and the terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) staining method. In the immunohistochemistry sense, while the BNP level in the AGTX-III groups did not vary significantly, an increase in dosage significantly increased the IL-6, IL-1β, and TNF-α levels in comparison to the control groups. In their comparison to the control groups, the BNP levels increase and the IL-6 and IL-1β levels decreased in the CGTX-III groups. TUNEL analysis revealed that apoptosis increased in both the acute and chronic groups.

Abstract
OBJECTIVE Anabolic-androgenic steroids (AAS) represents a group of synthetic testosterone derivatives that play an important role in clinical treatment. These drugs are widely abused among the general public to increase lean weight and improve athletic performance. It has been reported that AAS use can produce many adverse effects, especially the occurrence of cardiovascular risk. Although there are many related studies, there has been no consensus on AAS use and cardiovascular risk. The present study was to review the effect of AAS on the cardiovascular system. DATA SOURCES The data in this review were obtained from articles included in PubMed and the National Center for Biotechnology Information database. STUDY SELECTION Original articles, case reports, and systematic reviews about AAS were selected for the article. RESULTS The use/abuse of AAS is correlated with higher cardiovascular risks, and many AAS users/abusers had cardiovascular diseases. However, there are many confounding factors in the studies that explored the causality between AAS intake and disease development, and additional studies are required to determine AAS toxicity. CONCLUSION AAS produces toxic effects on the cardiovascular system, and it is necessary to ensure that more people know this about AAS, including medical personnel.

Abstract
Several studies have reported that high doses of synthetic anabolic androgenic steroids (AAS) can have serious negative effects on health, including the cardiovascular system. The aim of this study was to evaluate the combined effects of AAS and exercise training on ventricular repolarization and cardiac autonomic modulation in rats. Male Wistar rats were allocated into 4 groups: sedentary rats treated with vehicle, sedentary rats treated with nandrolone decanoate, swimming-trained rats treated with vehicle, and swimming-trained rats treated with nandrolone decanoate. Ventricular repolarization was evaluated by electrocardiographic analysis of QT interval and QT dispersion. Cardiac autonomic modulation was assessed by heart rate variability. Our results show that AAS increased QT interval and QT dispersion in sedentary rats treated with nandrolone decanoate as compared to sedentary rats treated with vehicle, indicating AAS-induced ventricular repolarization abnormalities. When rats treated with nandrolone decanoate were subjected to concomitant exercise training, ventricular repolarization was normalized. On the other hand, AAS-induced reduction in cardiac parasympathetic modulation was not prevented by exercise training. In conclusion, AAS produced cardiac autonomic dysfunction and ventricular repolarization disturbances in rats. Combining an exercise training protocol during the AAS treatment attenuated the ventricular repolarization abnormalities and did not prevent cardiac autonomic dysfunction.

Abstract
AbstractStanozolol is an anabolic-androgenic steroid which is commonly abused by athletes for improved energy, appearance, and physical size. It has been previously shown to cause changes in behaviour and has various physical effects. Studies have previously been conducted on its neurotoxic effect on the central nervous system (CNS), which are typically psychological in nature. This study was performed to investigate the apoptotic effect of stanozolol on different parts of the rat hippocampus. Sixteen male Wistar rats were divided randomly into two groups (experimental and control). The experimental group received subcutaneous injections of stanozolol (5mg/kg/day) for consecutive 28 days, whereas the control group received saline using the same dosing schedule and administration route. After routine procedures, coronal sections of rat brain were stained with Toluidine blue and TUNEL for pre-apoptotic and apoptotic cell detection, respectively. In order to compare groups, the mean number of TUNEL-positive and pre-apoptotic neurons per unit area were calculated and analysed. Histopathological examination revealed that the mean number of pre-apoptotic and apoptotic neurons in the CA1, CA2, CA3 and DG areas of the hippocampus were significantly increased in the stanozolol treated group. In conclusion, stanozolol abuse may induce pre-apoptotic and apoptotic cell formation in different regions of the hippocampus.

Abstract
Stanozolol is a widely used 17α-alkylated anabolic androgenic steroid (AAS) derivative. Despite stanozolol's adverse effects, its effect on oxidative stress parameters and mitochondrial apoptosis pathway is not clearly defined. In our study, thirty four male Sprague-Dawley rats were divided into 5 groups as control (C), vehicle control (VC), steroid (ST), vehicle control-exercise (VCE), and steroid-exercise (STE). Animals were subcutaneously administered stanozolol 5 mg/kg in steroid groups and propylene glycol 1 ml/kg in the vehicle-control groups. On the 28th day-after sacrification, oxidative stress (MDA, GSH, PC, SOD, CAT) and apoptosis parameters (TUNEL, Cytochrome-c) in cardiac tissue were evaluated. Also, blood vessel morphology of cardiac tissue was evaluated with Verhoeff-van Giesen staining. It has been demonstrated that stanozolol administration triggers apoptosis by using TUNEL assay and cytochrome-c immunohistochemical staining intensity, while this effect is significantly reduced in the presence of exercise. In conclusion, the present study demonstrated that stanozolol administration induces apoptosis with increasing PC and CAT levels, while GSH, MDA and SOD parameters do not reveal any significant change. Exercise has a protective role in stanozolol induced oxidative stress and apoptosis. According to Verhoeff-van Giesen staining results for blood vessel morphology assessment, it has been seen that exercise has a protective role on cardiac blood vessels. This mechanism needs further investigations with long term exposure studies for clarifying possible pathways.

Abstract
BACKGROUND Millions of individuals have used illicit anabolic-androgenic steroids (AAS), but the long-term cardiovascular associations of these drugs remain incompletely understood. METHODS Using a cross-sectional cohort design, we recruited 140 experienced male weightlifters 34 to 54 years of age, comprising 86 men reporting ≥2 years of cumulative lifetime AAS use and 54 nonusing men. Using transthoracic echocardiography and coronary computed tomography angiography, we assessed 3 primary outcome measures: left ventricular (LV) systolic function (left ventricular ejection fraction), LV diastolic function (early relaxation velocity), and coronary atherosclerosis (coronary artery plaque volume). RESULTS Compared with nonusers, AAS users demonstrated relatively reduced LV systolic function (mean±SD left ventricular ejection fraction = 52±11% versus 63±8%; P<0.001) and diastolic function (early relaxation velocity = 9.3±2.4 cm/second versus 11.1±2.0 cm/second; P<0.001). Users currently taking AAS at the time of evaluation (N=58) showed significantly reduced LV systolic (left ventricular ejection fraction = 49±10% versus 58±10%; P<0.001) and diastolic function (early relaxation velocity = 8.9±2.4 cm/second versus 10.1±2.4 cm/second; P=0.035) compared with users currently off-drug (N=28). In addition, AAS users demonstrated higher coronary artery plaque volume than nonusers (median [interquartile range] 3 [0, 174] mL3 versus 0 [0, 69] mL3; P=0.012). Lifetime AAS dose was strongly associated with coronary atherosclerotic burden (increase [95% confidence interval] in rank of plaque volume for each 10-year increase in cumulative duration of AAS use: 0.60 SD units [0.16-1.03 SD units]; P=0.008). CONCLUSIONS Long-term AAS use appears to be associated with myocardial dysfunction and accelerated coronary atherosclerosis. These forms of AAS-associated adverse cardiovascular phenotypes may represent a previously underrecognized public-health problem.

Abstract
The use of doping substances and methods is extensive not only among elite athletes, but also among amateur and recreational athletes. Many types of drugs are used by athletes to enhance performance, to reduce anxiety, to increase muscle mass, to reduce weight or to mask the use of other drugs during testing. However, the abuse of doping substances and methods has been associated with the occurrence of numerous health side-effects. The adverse effects depend on the type of the consumed drug, as well as the amount and duration of intake and the sensitivity of the body, since there is a large inter-individual variability in responses to a drug. Usually the doses used in sports are much higher than those used for therapeutic purposes and the use of several drugs in combination is frequent, leading to higher risk of side-effects. Among biomedical side-effects of doping, the cardiovascular ones are the most deleterious. Myocardial infarction, hyperlipidemia, hypertension, thrombosis, arrythmogenesis, heart failure and sudden cardiac death have been noted following drug abuse. This paper reviews the literature on the adverse cardiovascular effects after abuse of prohibited substances and methods in athletes, aiming to inform physicians, trainers and athletes and to discourage individuals from using drugs during sports.

Abstract
Despite worldwide use of anabolic steroids in last decades, there is still contradictory information about their acute influence on myocardium. The aim of this study was to examine the acute effects of nandrolone decanoate (ND) on cardiodynamics and coronary flow in isolated rat heart. The hearts of male Wistar albino rats (n = 48, 12 per group, age 8 weeks, body mass 180-200 g) were excised and perfused according to the Langendorff technique at gradually increased coronary perfusion pressures (40-120 cmH2O). After the control sets of experiments, the hearts in different groups were perfused with different doses of ND (1, 10, or 100 μmol/L separately). Using a sensor placed in the left ventricle, we registered maximum and minimum rate of pressure development in the left ventricle (dP/dtmax and dP/dtmin), systolic and diastolic left ventricular pressure (SLVP and DLVP), and heart rate (HR). Coronary flow (CF) was measured flowmetrically. The results clearly show the depression in cardiac function caused by higher doses of ND. The highest concentration of ND (100 μmol/L) induced the most deleterious impact on the myocardial function and perfusion of the heart (coronary circulation), which could be of clinical significance.

Abstract
Anabolic androgenic steroids (AAS) are some of the most common performance
enhancing drugs (PED) among society. Despite the broad spectrum of adverse effects and legal
consequences, AAS are illicitly marketed and distributed in many countries. To circumvent existing
laws, the chemical structure of AAS is modified and these designer steroids are sold as nutritional
supplements mainly over the Internet. Several side effects are linked with AAS abuse. Only little is
known about the pharmacological effects and metabolism of unapproved steroids due to the absence
of clinical studies. The large number of designer steroid findings in dietary supplements and the
detection of new compounds combined with legal loopholes for their distribution in many countries
show that stricter regulations and better information policy are needed.

Abstract
PURPOSE Chemotherapy with doxorubicin (Dox) causes dose-limiting cardiotoxicity. We investigated the role that gender has on cardiosensitivity to Dox treatment by evaluating reproductive hormone levels in male, castrated male (c-male), female and ovariectomized female (o-female) adult spontaneously hypertensive rats (SHRs) and expression of mitochondria-related genes in male and female adult SHRs. METHODS SST-2 breast tumor-bearing SHRs were treated with saline, Dox, dexrazoxane (Drz) or both Dox and Drz and monitored for 14 days. Tumor size was used to monitor anticancer activity. Heart weight, cardiac lesion score and serum levels of cardiac troponin T (cTnT) were used to determine cardiotoxicity. Serum estradiol (E2) and testosterone were evaluated using electrochemiluminescence immunoassays. Expression of mitochondria-related genes was profiled in heart by MitoChip array analyses. RESULTS Dox significantly reduced tumor volume (±Drz) and increased heart weight in all genders (13-30% vs. control). Higher heart lesion scores were observed in reproductively normal animals (male 2.9, female 2.2) than in hormone-deficient animals (c-male 1.7, o-female 1.9). Lesion score and cTnT inversely correlated with hormone levels. Reduced levels of both sex hormones were observed after Dox treatment. Gene expression analyses of Dox-treated hearts showed significant differential expression of oxidative stress genes in male hearts and apoptotic genes in both male and female hearts. CONCLUSIONS Our results demonstrate that adult tumor-bearing male SHRs are more cardiosensitive to Dox than female or hormone-deficient animals. We provide evidence to suggest that reproductive hormones negatively regulate or are inhibited by Dox-induced cardiotoxicity and the selective cytotoxic mechanism likely functions through the greater activation of oxidative stress and apoptosis in male SHRs.

Abstract
Human response to different physiologic stimuli and cardiovascular (CV) adaptation to various pathologies seem to be gender specific. Sex-steroid hormones have been postulated as the major contributors towards these sex-related differences. This review will discuss current evidence on gender differences in CV function and remodelling, and will present the different role of the principal sex-steroid hormones on female heart. Starting from a review of sex hormones synthesis, receptors and CV signalling, we will summarize the current knowledge concerning the role of sex hormones on the regulation of our daily activities throughout the life, via the modulation of autonomic nervous system, excitation-contraction coupling pathway and ion channels activity. Many unresolved questions remain even if oestrogen effects on myocardial remodelling and function have been extensively studied. So this work will focus attention also on the controversial and complex relationship existing between androgens, progesterone and female heart.

Abstract
Anabolic androgenic steroids lead to cardiac complications and have been shown to exhibit proapoptotic effects in cardiac cells; however, the mechanism involved in those effects is unclear. The aim of this study was to assess whether apoptosis and the activation of caspase-3 (Casp-3) induced by testosterone in high concentrations involves increments in tumor necrosis factor-α (TNF-α) concentrations and angiotensin-converting enzyme (ACE) activity in cardiomyocytes (H9c2) cell cultures. Cardiomyocytes were treated with testosterone (5 × 10−6 mol/L), doxorubicin (9.2 × 10−6 mol/L), testosterone + etanercept (Eta; 6.67 × 10−5 mol/L), testosterone + losartan (Los; 10−7 mol/L), and testosterone + AC-DEVD-CHO (10−5 mol/L; Casp-3 inhibitor). Apoptosis was determined by flow cytometry and by the proteolytic activity of Casp-3. We demonstrated that incubation of H9c2 cells for 48 h with testosterone causes the apoptotic death of 60–70% of the cells and co-treatments with Eta, Los, or AC-DEVD-CHO reduced this effect. Testosterone also induces apoptosis (concentration dependent) and increases the proteolytic activity of Casp-3, which were reduced by co-treatments. TNF-α and ACE activities were elevated by testosterone treatment, while co-treatment with Los and Eta reduced these effects. We concluded that an interaction between testosterone, angiotensin II, and TNF-α induced apoptosis and Casp-3 activity in cultured cardiomyocytes, which contributed to the reduced viability of these cells induced by testosterone in toxic concentrations.

Abstract
Anabolic-androgenic steroids (AAS) are synthetic substances derived from testosterone that are largely employed due to their trophic effect on muscle tissue of athletes at all levels. Since a great number of organs and systems are a target of AAS, their adverse effects are primarily on the following systems: reproductive, hepatic, musculoskeletal, endocrine, renal, immunological, infectious, cardiovascular, cerebrovascular, and hematological. Neuropsychiatric and behavioral effects as a result of AAS abuse are well known and described in the literature. Mounting evidence exists suggesting that in addition to psychiatric and behavioral effects, non-medical use of AAS carries neurodegenerative potential. Although, the nature of this association remains largely unexplored, recent animal studies have shown the recurrence of this AAS effect, ranging from neurotrophin unbalance to increased neuronal susceptibility to apoptotic stimuli. Experimental and animal studies strongly suggest that apoptotic mechanisms are at least in part involved in AAS-induced neurotoxicity. Furthermore, a great body of evidence is emerging suggesting that increased susceptibility to cellular oxidative stress could play a pivotal role in the pathogenesis of many neurodegenerative disorders and cognitive impairment. As in other drug-evoked encephalopathies, the key mechanisms involved in AAS - induced neuropathology could represent a target for future neuroprotective strategies. Progress in the understanding of these mechanisms will provide important insights into the complex pathophysiology of AAS-induced neurodegeneration, and will pave the way for forthcoming studies. Supplementary to abandoning the drug abuse that represents the first step in reducing the possibility of irreversible brain damage in AAS abusers, neuroprotective strategies have to be developed and implemented in future.

Abstract
Despite the high prevalence of performance-enhancing drug (PED) use, media attention has focused almost entirely on PED use by elite athletes to illicitly gain a competitive advantage in sports, and not on the health risks of PEDs. There is a widespread misperception that PED use is safe or that adverse effects are manageable. In reality, the vast majority of PED users are not athletes but rather nonathlete weightlifters, and the adverse health effects of PED use are greatly underappreciated. This scientific statement synthesizes available information on the medical consequences of PED use, identifies gaps in knowledge, and aims to focus the attention of the medical community and policymakers on PED use as an important public health problem. PED users frequently consume highly supraphysiologic doses of PEDs, combine them with other PEDs and/or other classical drugs of abuse, and display additional associated risk factors. PED use has been linked to an increased risk of death and a wide variety of cardiovascular, psychiatric, metabolic, endocrine, neurologic, infectious, hepatic, renal, and musculoskeletal disorders. Because randomized trials cannot ethically duplicate the large doses of PEDs and the many factors associated with PED use, we need observational studies to collect valid outcome data on the health risks associated with PEDs. In addition, we need studies regarding the prevalence of PED use, the mechanisms by which PEDs exert their adverse health effects, and the interactive effects of PEDs with sports injuries and other high-risk behaviors. We also need randomized trials to assess therapeutic interventions for treating the adverse effects of PEDs, such as the anabolic-androgen steroid withdrawal syndrome. Finally, we need to raise public awareness of the serious health consequences of PEDs.

Abstract
Although reperfusion of an ischemic organ is essential to prevent irreversible tissue damage, it may amplify tissue injury. This study investigates the role of endogenous testosterone in myocardial ischemia reperfusion and apoptosis in male rats. Material and method. Twenty four male rats were randomized into 4 equal groups: Group (1), sham group, rats underwent the same anesthetic and surgical procedure as the control group except for LAD ligation; Group (2), Active control group, rats underwent LAD ligation; Group (3), castrated, rats underwent surgical castration, left 3wks for recovery, and then underwent LAD ligation; and Group (4), Goserelin acetate treated, rats received 3.6 mg of Goserelin 3 wks before surgery and then underwent LAD ligation. At the end of experiment, plasma cTn I, cardiac TNF-α, IL1-β, ICAM-1, and Apoptosis level were measured and histological examination was made. Results. Compared to sham group, the levels of myocardial TNF-α, IL-1β, ICAM-1, apoptosis, and plasma cTn I were significantly increased (P < 0.05) in control group and all rats showed significant myocardial injury (P < 0.05). Castration and Goserelin acetates significantly counteract the increase in myocardial levels of TNF-α, IL-1β, ICAM-1, plasma cTn I, and apoptosis (P < 0.05) and significantly reduce (P < 0.05) the severity of myocardial injury. We conclude that castration and Goserelin acetates ameliorate myocardial I/R injury and apoptosis in rats via interfering with inflammatory reactions.

Abstract
PURPOSE Anabolic steroid (AS) misuse is widespread amongst recreational bodybuilders; however, their effects on the cardiovascular system are uncertain. Our aim was to document the impact of AS use on cardiac structure, function and the presence of focal fibrosis using the gold standard cardiovascular magnetic resonance imaging (CMR). METHODS A cross-sectional cohort design was utilised with 21 strength-trained participants who underwent CMR imaging of the heart and speckle-tracking echocardiography. Thirteen participants (30 ± 5 years) taking AS for at least 2 years and currently on a "using"-cycle were compared with age and training-matched controls (n = 8; 29 ± 6 years) who self-reported never having taken AS (NAS). RESULTS AS users had higher absolute left ventricular (LV) mass (220 ± 45 g) compared to NAS (163 ± 27 g; p < 0.05) but this difference was removed when indexed to fat-free mass. AS had a reduced right ventricular (RV) ejection fraction (AS 51 ± 4 % vs. NAS 59 ± 5 %; p < 0.05) and a significantly lower left ventricular E':A' myocardial tissue velocity ratio [AS 0.99(0.54) vs. NAS 1.78(0.46) p < 0.05] predominantly due to greater tissue velocities with atrial contraction. Peak LV longitudinal strain was lower in AS users (AS -14.2 ± 2.7 % vs. NAS -16.6 ± 1.9 %; p < 0.05). There was no evidence of focal fibrosis in any participant. CONCLUSIONS AS use was associated with significant LV hypertrophy, albeit in-line with greater fat-free mass, reduced LV strain, diastolic function, and reduced RV ejection fraction in male bodybuilders. There was, however, no evidence of focal fibrosis in any AS user.

Effectiveness of Panax ginseng on Acute Myocardial Ischemia Reperfusion Injury Was Abolished by Flutamide via Endogenous Testosterone-Mediated Akt Pathway. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:817826.

Abstract
Mechanisms for Panax ginseng's cardioprotective effect against ischemia reperfusion injury involve the estrogen-mediated pathway, but little is known about the role of androgen. A standardized Panax ginseng extract (RSE) was orally given with or without flutamide in a left anterior descending coronary artery ligation rat model. Infarct size, CK and LDH activities were measured. Time-related changes of NO, PI3K/Akt/eNOS signaling, and testosterone concentration were also investigated. RSE (80 mg/kg) significantly inhibited myocardial infarction and CK and LDH activities, while coadministration of flutamide abolished this effect of RSE. NO was increased by RSE and reached a peak after 15 min of ischemia; however, flutamide cotreatment suppressed this elevation. Western blot analysis showed that RSE significantly reversed the decreases of expression and activation of PI3K, Akt, and eNOS evoked by ischemia, whereas flutamide attenuated the effects of these protective mechanisms induced by RSE. RSE completely reversed the dropping of endogenous testosterone level induced by I/R injury. Flutamide plus RSE treatment not only abolished RSE's effect but also produced a dramatic change on endogenous testosterone level after pretreatment and ischemia. Our results for the first time indicate that blocking androgen receptor abolishes the ability of Panax ginseng to protect the heart from myocardial I/R injury.

Abstract
OBJECTIVES To investigate the effects of exercise training and anabolic androgenic steroids (AAS) on hemodynamics, glycogen content, angiogenesis, apoptosis and histology of cardiac muscle. METHODS Forty rats were divided into 4 groups; control, steroid, exercise-trained and exercise-trained plus steroid groups. The exercise-trained and trained plus steroid groups, after one week of water adaptation, were exercised by jumping into water for 5 weeks. The steroid and trained plus steroid groups received nandrolone decanoate, for 5 weeks. Systolic blood pressure and heart rate (HR) were monitored weekly. Heart weight/body weight ratio (HW/BW ratio) were determined. Serum testosterone, vascular endothelial growth factor (VEGF), cardiac caspase-3 activity and glycogen content were measured. RESULTS Compared with control, the steroid group had significantly higher blood pressure, HR, sympathetic nerve activity, testosterone level, HW/BW and cardiac caspase-3 activity. Histological examination revealed apoptotic changes and hypertrophy of cardiomyocytes. In exercise-trained group, cardiac glycogen, VEGF and testosterone levels were significantly higher while HR was significantly lower than control. HW/BW was more than control confirmed by hypertrophy of cardiomyocytes with angiogenesis on histological examination. Trained plus steroid group, had no change in HR, with higher blood pressure and HW/BW than control, cardiac glycogen and serum VEGF were higher than control but lower than exercise-trained group. Histological examination showed hypertrophy of cardiomyoctes with mild angiogenesis rather than apoptosis. CONCLUSION When exercise is augmented with AAS, exercise-associated cardiac benefits may not be fully gained with potential cardiac risk from AAS if used alone or combined with exercise.

Cognitive deficits in long-term anabolic-androgenic steroid users. Drug Alcohol Depend 2013; 130:208-14.

Abstract
BACKGROUND Millions of individuals worldwide have used anabolic-androgenic steroids (AAS) to gain muscle or improve athletic performance. Recently, in vitro investigations have suggested that supraphysiologic AAS doses cause apoptosis of neuronal cells. These findings raise the possibility, apparently still untested, that humans using high-dose AAS might eventually develop cognitive deficits. METHODS We administered five cognitive tests from the computerized CANTAB battery (Pattern Recognition Memory, Verbal Recognition Memory, Paired Associates Learning, Choice Reaction Time, and Rapid Visual Information Processing) to 31 male AAS users and 13 non-AAS-using weightlifters age 29-55, recruited and studied in May 2012 in Middlesbrough, UK. Testers were blinded to participants' AAS status and other historical data. RESULTS Long-term AAS users showed no significant differences from nonusers on measures of response speed, sustained attention, and verbal memory. On visuospatial memory, however, AAS users performed significantly more poorly than nonusers, and within the user group, visuospatial performance showed a significant negative correlation with total lifetime AAS dose. These were large effects: on Pattern Recognition Memory, long-term AAS users underperformed nonusers by almost one standard deviation, based on normative population scores (adjusted mean difference in z-scores=0.89; p=0.036), and performance on this test declined markedly with increasing lifetime AAS dose (adjusted change in z-score=-0.13 per 100g of lifetime AAS dose; p=0.002). These results remained stable in sensitivity analyses addressing potential confounding factors. CONCLUSIONS These preliminary findings raise the ominous possibility that long-term high-dose AAS exposure may cause cognitive deficits, notably in visuospatial memory.

Abstract
To evaluate the impact potential of nandrolone decanoate on DNA damage in multiple organs of Wistar rats by means of single-cell gel (comet) assay and micronucleus test. A total of 15 animals were distributed into three groups of five animals each as follows: control group = animal not exposed to nandrolone decanoate; experimental group = animals exposed to nandrolone decanoate for 24 h at 5 mg/kg subcutaneously; and experimental group = animals exposed to nandrolone decanoate for 24 h at 15 mg/kg subcutaneously. Significant statistical differences (p < 0.05) were noted in peripheral blood, liver, and heart cells exposed to nandrolone decanoate at the two doses evaluated. A clear dose-response relationship was observed between groups. Kidney cells showed genetic damage at only the highest dose (15 mg/kg) used. However, micronucleus data did not show remarkable differences among groups. In conclusion, the present study indicates that nandrolone decanoate induces genetic damage in rat blood, liver, heart, and kidney cells as shown by single-cell gel (comet) assay results.

Abstract
Andropause refers to a generalized decline of male hormones, including testosterone and dehydroepiandrosterone in middle-aged and aging men. This decline in hormones has been associated with changes such as depression, loss of libido, sexual dysfunction, and changes in body composition. Aging has been associated with an abundance of concomitant diseases, in particular cardiovascular diseases, and although andropause is correlated to aging, a causal relationship between reduction of androgens and the development of chronic diseases such as atherosclerosis and heart failure has not been convincingly established yet. On the other hand, increasing data has emerged that revealed the effects of low levels of androgens on cardiovascular disease progression. As an example, low levels of testosterone have been linked to a higher incidence of coronary artery disease. Whether hormone replacement therapy that is used for andropausal men to alleviate symptoms of "male menopause" can halt progression of cardiovascular disease, remains controversially discussed, primarily due to the lack of well-designed, randomized controlled trials. At least for symptom improvement, the use of androgen replacement therapy in andropausal men may be clinically indicated, and with the appropriate supervision and follow up may prove to be beneficial with regard to preservation of the integrity of cardiovascular health at higher ages.

Abstract
This study was aimed at evaluation of changes in activities of selected antioxidant enzymes (superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase) and contents of key nonenzymatic antioxidants (glutathione, protein thiol groups, and α- and γ-tocopherols) in the left heart ventricle of young male Wistar rats subjected to endurance training (treadmill running, 1 h daily, 5 days a week, for 6 weeks) or/and testosterone propionate treatment (8 or 80 mg/kg body weight, intramuscularly, once a week, for 6 weeks) during adolescence. The training alone increased the activities of key antioxidant enzymes, but lowered the pool of nonenzymatic antioxidants and enhanced myocardial oxidative stress as evidenced by elevation of the lipid peroxidation biomarker malondialdehyde. The lower-dose testosterone treatment showed mixed effects on the individual components of the antioxidant defense system, but markedly enhanced lipid peroxidation. The higher-dose testosterone treatment decreased the activities of the antioxidant enzymes, lowered the contents of the nonenzymatic antioxidants, except for that of γ-tocopherol, reversed the effect of endurance training on the antioxidant enzymes activities, and enhanced lipid peroxidation more than the lower-dose treatment. These data demonstrate the potential risk to cardiac health from exogenous androgen use, either alone or in combination with endurance training, in adolescents.

Abstract
Background Androgen abuse is an increasing problem amongst professional and amateur athletes. Moreover, testosterone, apart from its widely accepted indications, is used for a variety of other indications such as aging and ischemia. Its actions are mainly attributed to a specific genomic mechanism through the androgen receptor, but emerging evidence reveals non-genomic effects as well. The use of androgens has been linked with several adverse effects. The purpose of this study was to examine the effects of testosterone on the morphology and the ultrastructure of the myocardium and to investigate the possible role of apoptosis. Material/Methods We used 12 adult male Wistar rats, separated into 2 groups. Group A consisted of 6 rats that were administered high doses of testosterone enanthate, while group B consisted of 6 male Wistar rats that received placebo (normal saline) intramuscularly. After the last day of treatment, all rats were anesthetized and sacrificed, and the hearts were removed and processed for optical and electron microscopy and immunohistochemical detection of caspase-3, an apoptosis marker. Results We found significant myocardial hypertrophy along with abundant ultrastructural alterations. The immunohistochemical staining of the myocardial cells for caspase-3 was positive in group A (experimental group), which is interpreted as an activation of apoptosis by testosterone treatment. Conclusions Testosterone abuse has serious adverse effects, including myocardial hypertrophy, myocardial fibrosis and activation of apoptosis. These findings need to be taken into account whenever androgens are prescribed to improve performance or as hormone therapy.

Abstract
Increasing evidence suggests that nongenomic effects of testosterone and anabolic androgenic steroids (AAS) operate concertedly with genomic effects. Classically, these responses have been viewed as separate and independent processes, primarily because nongenomic responses are faster and appear to be mediated by membrane androgen receptors, whereas long-term genomic effects are mediated through cytosolic androgen receptors regulating transcriptional activity. Numerous studies have demonstrated increases in intracellular Ca2+ in response to AAS. These Ca2+ mediated responses have been seen in a diversity of cell types, including osteoblasts, platelets, skeletal muscle cells, cardiac myocytes and neurons. The versatility of Ca2+ as a second messenger provides these responses with a vast number of pathophysiological implications. In cardiac cells, testosterone elicits voltage-dependent Ca2+ oscillations and IP3R-mediated Ca2+ release from internal stores, leading to activation of MAPK and mTOR signaling that promotes cardiac hypertrophy. In neurons, depending upon concentration, testosterone can provoke either physiological Ca2+ oscillations, essential for synaptic plasticity, or sustained, pathological Ca2+ transients that lead to neuronal apoptosis. We propose therefore, that Ca2+ acts as an important point of crosstalk between nongenomic and genomic AAS signaling, representing a central regulator that bridges these previously thought to be divergent responses.

Abstract
Acute stroke could be the presentation of unrecognised cardiomyopathy postanabolic androgenic steroid (AAS) abuse. A 39-year-old male patient displayed signs of acute stroke, which were associated with AAS abuse over the last 3 years. Despite the absence of symptoms and signs of congestive heart failure at presentation, AAS-induced cardiomyopathy with a thrombus in the left ventricle was discovered to be the aetiology of his stroke and peripheral vascular disease. Awareness of the complications of AAS led to the prompt treatment of the initially unrecognised dilated cardiomyopathy, and stroke.

Abstract
The aim of the present study was to evaluate DNA damage (micronucleus) and cellular death (pyknosis, karyolysis and karyorrhexis) in exfoliated buccal mucosa cells from anabolic steroid users after 2 months of exposure. Two experimental groups consisting of 15 adult males who practise weight lifting and are anabolic steroid users or 15 adult males who practise weight lifting, but are non-anabolic steroid users, were recruited. In addition, 20 sedentary males, who do not practise any physical activity regularly, were matched by age with experimental groups. No significant statistical differences (p>0.05) were noticed in individuals who practise physical activity only. On the other hand, an increase of micronucleated cells (MNCs) in anabolic steroid (decadurabulin and Winstrol) users was observed. Regarding cytotoxic parameters, the same observation has occurred, that is, significant statistical differences (p<0.05) were noticed in the group exposed to anabolic steroids when compared with other controls, as depicted by high frequencies of pyknosis, karyolysis and karyorrhexis. Taken together, our results suggest that genomic instability and cytotoxicity are induced by anabolic steroid administration in oral mucosa cells as assessed by the micronucleus test.

Abstract
Recent surveys and reports suggest that many athletes and bodybuilders abuse anabolic-androgenic steroids (AAS). However, scientific data on the cardiac and metabolic complications of AAS abuse are divergent and often conflicting. A total of 49 studies describing 1,467 athletes were reviewed to investigate the cardiovascular effects of the abuse of AAS. Although studies were typically small and retrospective, some associated AAS abuse with unfavorable effects. Otherwise healthy young athletes abusing AAS may show elevated levels of low-density lipoprotein and low levels of high-density lipoprotein. Although data are conflicting, AAS have also been linked with elevated systolic and diastolic blood pressure and with left ventricular hypertrophy that may persist after AAS cessation. Finally, in small case studies, AAS abuse has been linked with acute myocardial infarction and fatal ventricular arrhythmias. In conclusion, recognition of these adverse effects may improve the education of athletes and increase vigilance when evaluating young athletes with cardiovascular abnormalities.

Abstract
The illicit use of supraphysiological doses of androgenic steroids (AAS) has been suggested as a cause of arrhythmia in athletes. The objectives of the present study were to investigate the time-course and the cellular, ionic and molecular processes underlying ventricular repolarization in rats chronically treated with AAS. Male Wistar rats were treated weekly for 8 weeks with 10mg/kg of nandrolone decanoate (DECA n=21) or vehicle (control n=20). ECG was recorded weekly. Action potential (AP) and transient outward potassium current (I(to)) were recorded in rat hearts. Expression of KChIP2, Kv1.4, Kv4.2, and Kv4.3 was assessed by real-time PCR. Hematoxylin/eosin and Picrosirius red staining were used for histological analysis. QTc was greater in the DECA group. After DECA treatment the left, but not right, ventricle showed a longer AP duration than did the control. I(to) current densities were 47.5% lower in the left but not in the right ventricle after DECA. In the right ventricle the I(to) inactivation time-course was slower than in the control group. After DECA the left ventricle showed lower KChIP2 ( approximately 26%), Kv1.4 ( approximately 23%) and 4.3 ( approximately 70%) expression while the Kv 4.2 increased in 4 ( approximately 250%) and diminished in 3 ( approximately 30%) animals of this group. In the right ventricle the expression of I(to) subunits was similar between the treatment and control groups. DECA-treated hearts had 25% fewer nuclei and greater nuclei diameters in both ventricles. Our results strongly suggest that supraphysiological doses of AAS induce morphological remodeling in both ventricles. However, the electrical remodeling was mainly observed in the left ventricle.

Abstract
BACKGROUND The chronic consumption of androgenic anabolic steroids (AAS) has shown to cause subclinical impairment of myocardial function. Pulsed-wave Doppler tissue imaging (PWDTI) detects early regional alterations of ventricular function, whereas integrated backscatter cyclic variations (IBScv) are tightly related to the contractile efficiency of the left ventricular wall. The aim of this study was to identify the effects of chronic AAS misuse on myocardial function using both PWDTI and IBScv. METHODS Twenty-eight male bodybuilders (11 AAS users, 17 AAS nonusers) and 20 healthy sedentary subjects (controls), matched according to age, were studied. To assess left ventricular function, each subject underwent standard Doppler echocardiography, PWDTI, and IBScv analyses. RESULTS Left ventricular mass was significantly higher in AAS users than in AAS nonusers and controls. Global systolic function (assessed by determining the ejection fraction) was similar in all subjects, but isovolumetric relaxation time was significantly higher in AAS users than in controls. On PWDTI analysis, AAS users showed regional systolic and diastolic dysfunction (evaluated by measuring s', e', and a') not detectable in the other two groups. IBScv identified regional systolic impairment only in AAS users at the level of the left ventricular inferior wall. CONCLUSIONS The present study confirms that in AAS users, PWDTI and IBScv are effective and reliable noninvasive diagnostic tools for detecting early abnormalities of the systolic and diastolic longitudinal myocardial function, probably related to an increase in myocardial collagen content, interpretable as a repair process against the direct cellular injury produced by AAS.

Abstract
Abuse of anabolic androgenic steroids (AAS) has been linked to a variety of different cardiovascular side effects. In case reports, acute myocardial infarction is the most common event presented, but other adverse cardiovascular effects such as left ventricular hypertrophy, reduced left ventricular function, arterial thrombosis, pulmonary embolism and several cases of sudden cardiac death have also been reported. However, to date there are no prospective, randomized, interventional studies on the long-term cardiovascular effects of abuse of AAS. In this review we have studied the relevant literature regarding several risk factors for cardiovascular disease where the effects of AAS have been scrutinized:(1) Echocardiographic studies show that supraphysiologic doses of AAS lead to both morphologic and functional changes of the heart. These include a tendency to produce myocardial hypertrophy (Fig. 3), a possible increase of heart chamber diameters, unequivocal alterations of diastolic function and ventricular relaxation, and most likely a subclinically compromised left ventricular contractile function. (2) AAS induce a mild, but transient increase of blood pressure. However, the clinical significance of this effect remains modest. (3) Furthermore, AAS confer an enhanced pro-thrombotic state, most prominently through an activation of platelet aggregability. The concomitant effects on the humoral coagulation cascade are more complex and include activation of both pro-coagulatory and fibrinolytic pathways. (4) Users of AAS often demonstrate unfavorable measurements of vascular reactivity involving endothelial-dependent or endothelial-independent vasodilatation. A degree of reversibility seems to be consistent, though. (5) There is a comprehensive body of evidence documenting that AAS induce various alterations of lipid metabolism. The most prominent changes are concomitant elevations of LDL and decreases of HDL, effects that increase the risk of coronary artery disease. And finally, (6) the use of AAS appears to confer an increased risk of life-threatening arrhythmia leading to sudden death, although the underlying mechanisms are still far from being elucidated. Taken together, various lines of evidence involving a variety of pathophysiologic mechanisms suggest an increased risk for cardiovascular disease in users of anabolic androgenic steroids.

Abstract
BACKGROUND Signal transducer and activator of transduction 3 (STAT3) pathway has been shown to be cardioprotective. We observed decreased STAT3/suppressor of cytokine signaling 3 (SOCS3) in male hearts, which was associated with worse postischemic myocardial function compared with females. However, it is unclear whether this downregulation of myocardial STAT3/SOCS3 is due to testosterone in males. We hypothesized that after ischemia/reperfusion (I/R), (1) endogenous testosterone decreases myocardial STAT3 and SOCS3 in males, and (2) administration of exogenous testosterone reduces myocardial STAT3/SOCS3 in female and castrated male hearts. METHODS To study this, hearts from I/R injury (Langendorff) were homogenized and assessed for phosphorylated-STAT3 (p-STAT3), total-STAT3 (T-STAT3), SOCS3, and GAPDH by Western blot. We grouped age-matched adult males, females, castrated males, males with androgen receptor blocker-flutamide implantation, females, and castrated males with chronic (3-week) 5alpha-dihydrotestosterone (DHT) release pellet implantation or acute (5-minute) testosterone infusion (ATI) before ischemia (n = 5-9 per group). RESULTS Castration or flutamide treatment significantly increased SOCS3 expression in male hearts after I/R. However, only castration increased myocardial STAT3 activation. Notably, DHT replacement or ATI decreased markedly myocardial STAT3/SOCS3 in castrated males and females subjected to I/R. CONCLUSION These results suggest that endogenous and exogenous testosterone decrease myocardial STAT3 activation and SOCS3 expression after I/R. This represents the initial demonstration of testosterone-downregulated STAT3/SOCS3 signaling in myocardium.

Abstract
BACKGROUND Athletes use androgenic-anabolic steroids to increase strength and muscle mass. Several case reports suggest that it may lead to dilated cardiomyopathy. METHODS AND RESULTS We report a case of a 41-year-old bodybuilder with severe systolic dysfunction and Class IV heart failure despite maximal medical therapy. He used anabolic steroids and insulin growth factor, and did not have any other risk factors for cardiomyopathy. We briefly review the literature and summarize other reported cases with similar scenarios. In most of them cardiomyopathy was at least partially reversible after discontinuation of anabolics. CONCLUSIONS Abuse of anabolic steroids may be an uncommon cause of cardiomyopathy in young and otherwise healthy individuals.

Abstract
Among 15,000 forensic post-mortem examinations performed on the coroner's order over a 24-year period (January 1981-December 2004) in the area of Lyon, France (population: 2,000,000), 2250 cases of unexpected cardiac sudden death were identified retrospectively according to WHO criteria. Of these, 108 occurred during recreational sport and 12 occurred in athletes. In the latter category, a history of anabolic steroid abuse was found in 6 cases, whereas pre-existing ordinary cardiac lesions were observed in the 6 remaining cases. To shed light on the possible role of anabolic steroids in the induction of cardiac lesions, an experimental study was conducted in rabbits that were treated orally with norethandrolone 8mg/kg/day for 60 days, and sacrificed at day 90. The histopathological examination of the heart from treated animals showed coronary thrombosis associated with left ventricle hypertrophy in 3 cases, and lesions analogous to toxic or adrenergic myocarditis in all other treated animals. These findings were very similar to those observed after cardiac sudden death in the 6 athletes with a history of anabolic steroid abuse. In addition, elevated caspase-3 activity in the heart of treated rabbits as compared to controls suggests that apoptosis is involved in the induction of norethandrolone-induced cardiac lesions. These results confirm the cardiotoxic potential of anabolic steroid abuse.

Abstract
BACKGROUND The problem of anabolic-androgenic steroid (AAS) abuse has recently generated widespread public and media attention. Most AAS abusers, however, are not elite athletes like those portrayed in the media, and many are not competitive athletes at all. This larger but less visible population of ordinary AAS users began to emerge in about 1980. The senior members of this population are now entering middle age; they represent the leading wave of a new type of aging former substance abusers, with specific medical and psychiatric risks. METHODS We reviewed the evolving literature on long-term psychiatric and medical consequences of AAS abuse. RESULTS Long-term use of supraphysiologic doses of AAS may cause irreversible cardiovascular toxicity, especially atherosclerotic effects and cardiomyopathy. In other organ systems, evidence of persistent toxicity is more modest, and interestingly, there is little evidence for an increased risk of prostate cancer. High concentrations of AAS, comparable to those likely sustained by many AAS abusers, produce apoptotic effects on various cell types, including neuronal cells--raising the specter of possibly irreversible neuropsychiatric toxicity. Finally, AAS abuse appears to be associated with a range of potentially prolonged psychiatric effects, including dependence syndromes, mood syndromes, and progression to other forms of substance abuse. However, the prevalence and severity of these various effects remains poorly understood. CONCLUSIONS As the first large wave of former AAS users now moves into middle age, it will be important to obtain more systematic data on the long-term psychiatric and medical consequences of this form of substance abuse.
