Abstract
BACKGROUND A link between androgen use and the risk of cancers, especially prostate and breast cancer, has been suggested. The knowledge about a possible association is limited. OBJECTIVE The study aimed to investigate cancer incidence rates, particularly those related to prostate and breast cancer, in male androgen users and compare them to a control group. METHODS We included male androgen users identified through a nationwide anti-doping testing program in Danish fitness centers from 2006 to 2018. We paired each case with 50 male controls of the same age, selected randomly. The cohort was followed from baseline and until 2023. The outcome was the incidence of prostate cancer, breast cancer, or any cancer excluding non-melanoma skin cancer. RESULTS The study included 1,189 androgen users and 59,450 controls, with a mean age of 27 years at enrolment. During the follow-up period with a mean length of 11 years, 13 androgen users, and 612 controls were diagnosed with cancer. This resulted in an incidence rate ratio of 1.05 (95% CI: 0.55-1.81). None of the androgen users were diagnosed with prostate or breast cancer. DISCUSSION AND CONCLUSION Male androgen users did not face an increased short-term risk of cancer, neither overall nor related to prostate or breast cancer. Our study indicates that the absolute risk of malignancies in androgen users is comparable to that in the background population. However, we cannot exclude androgens as a cancer risk factor due to the limited sample size, relatively short follow-up period, and subject age.

Abstract
INTRODUCTION Meningiomas frequently occur within the field of neuro-oncology, but it is unclear whether exogenous or imbalanced endogenous hormones are involved in the pathophysiology. A previous case-control study found an almost 20-fold increase in the risk of developing meningioma among users of androgenic anabolic steroids. We, therefore, investigated this hypothesis. METHODS We compared the incidence rate of meningioma in a cohort of males sanctioned for the use of androgenic anabolic steroids with age- and sex-matched controls with an identical enrollment date. RESULTS We followed 1189 males sanctioned for using androgenic anabolic steroids for a total of 13,305 person-years and found 0 cases of meningioma. The control cohort of 59,450 males was followed for a total of 654,938 person-years, and 16 were diagnosed with meningioma. Thus, the incidence rate ratio was 0 (95% CI: 0-12.8). CONCLUSION We did not find any evidence supporting the hypothesis of an increased risk of meningioma development with the use of androgenic anabolic steroids. Due to the limited sample size, we cannot exclude androgenic anabolic steroids as a potential risk factor for meningioma development, despite the lack of apparent evidence in this study.

Abstract
BACKGROUND Knowledge within the field of multiple sclerosis treatment during pregnancy is vital to ensure the most optimal clinical practice. Immunomodulatory treatment in pregnancy could in theory affect the normal development and maturation of the immune system of the fetus with a potential increased risk of infections, consequently. We therefore set out to investigate whether exposure to interferon-beta in utero affected the risk of acquiring infections in early childhood. METHODS This retrospective matched cohort study utilized data from the Danish Multiple Sclerosis Registry linked with national Danish registries to identify all children born of mothers with MS in Denmark from 1998 to 2018. The study included 510 children exposed to interferon-beta in utero. The children were matched 1:1 on various of demographic characteristics with children born to mothers with untreated MS and 1:3 with children born to mothers without MS. Each child was followed for up to five years. Using individual-level data, we investigated all-cause mortality, rate of hospital admissions due to infections, and redeemed prescriptions of antibiotics. The primary statistical model applied was a negative binomial regression analysis. RESULTS We found no differences in childhood mortality, for hospital admissions the rate ratio compared to healthy controls was 0.79 (0.62-1.00). Regarding antibiotic prescriptions, the results were similar (RR 1.00 (0.90-1.11). Furthermore, we found no certain dose-response relationship between interferon-beta exposure duration and hospital admission rate (P = 0.47) or redeemed antibiotic prescription (P = 0.71). CONCLUSION Exposure to interferon-beta during gestation has little to no impact on the risk of acquiring significant infections during the first five years of childhood.

Abstract
INTRODUCTION Male gender is an important risk factor of central serous chorioretinopathy (CSC), and studies have explored the pathophysiological role of androgens in CSC with conflicting results. In this study, we shed light on this hot topic by exploring the risk of CSC in a large cohort of male androgen abusers. METHODS This study included male androgen abusers identified through a nationwide anti-doping test program across Danish fitness centers from January 3 2006 to March 1 2018. For each case, we randomly sampled ten male controls using Danish nationwide registries. These controls were matched in age and date. Cases and controls were followed until May 16 2018. Data on diagnoses were extracted using the Danish National Registry of Patients using ICD-10 codes to identify cases with CSC. RESULTS We included 1189 cases and 11,890 controls. Mean age at the time of doping sentence was 27.4 ± 6.9 years, and mean length of follow-up was 15.8 ± 3.6 years. We identified no cases of CSC in androgen abusers, and five cases of CSC in the control cohort. The difference between groups was not statistically significant (P = 1.0). CONCLUSIONS Male androgen abusers were not at increased risk of CSC. Considering the lack of any signal in this large study, we speculate that if male androgen plays any direct role in the pathophysiology of CSC, its role may be subtle at best.

Abstract
CASE A 50-year-old healthy man with normal kidney function underwent surgery for fracture-related infection. Unfortunately, the patient received 2.5 times the intended dose of tobramycin pellets in the medullary cavity and developed acute kidney failure. Given the intraosseous administration of tobramycin, the drug displayed an absorption-dependent pharmacokinetics and multiple treatments with hemodialysis were needed. However, the patient had a complete recovery, and the kidney function remained normal at the 2-year follow-up. CONCLUSION Tobramycin pellets are nephrotoxic in supratherapeutic doses; however, it was reversible in this case. Owing to the intraosseous administration, multiple treatments with hemodialysis were required.

Abstract
Anabolic steroid abuse is a growing health concern due to its relatively prevalent use and adverse health effects. These drugs cause significant disturbances of the body's endocrine system, and the most common somatic adverse drug reactions are gynaecomastia, infertility, testicular dysfunction, and acne. Furthermore, the use of anabolic steroids is associated with a variety of psychiatric disorders and antisocial behaviour as summarised in this review.

Abstract
PURPOSE Previous research has found that male users of androgens are diagnosed approximately twice as often with infertility. We therefore set out to investigate the fertility in men using androgens. METHODS The study included 545 males who tested positive for androgens in an anti-doping test program in Danish fitness centers during the period from January 3, 2006, to March 1, 2018. The confirmed androgen users were matched by birth year with 5450 male controls. We followed this cohort from 10 years prior to testing positive until the end of follow-up in May 2018. RESULTS During the 10-year period prior to testing positive, the group of androgen users experienced a 26% lower fertility rate than the controls (rate ratio [RR] 0.74; 95% CI, 0.60-0.90; P = 0.0028). However, in the years following the doping sanction, they made a significant catch-up, and at completed follow-up the total fertility rate was only 7% lower than expected (RR 0.93, 95% CI, 0.84-1.03). The prevalence of assisted reproduction was 5.69% in the group of androgen users and 5.28% in the control group (P = 0.69). CONCLUSION Androgen use was associated with a temporary decline in fertility and most androgen users achieved parenthood without any help from the health care system. Overall, the fertility rate and the prevalence of assisted reproduction among androgen users were close to those in the background population.

Abstract
Abstract
Aims
Quantitative computed tomography (QCT) allows assessment of morphological features of coronary atherosclerosis. We aimed to test the hypothesis that clinical patient presentation is associated with distinct morphological features of coronary atherosclerosis.
Methods and results
A total of 1652 participants, representing a spectrum of clinical risk profiles [787 asymptomatic individuals from the general population, 468 patients with acute chest pain without acute coronary syndrome (ACS), and 397 patients with acute chest pain and ACS], underwent multidetector computed tomography. Of these, 274 asymptomatic individuals, 254 patients with acute chest pain without ACS, and 327 patients with acute chest pain and ACS underwent QCT to assess coronary plaque volumes and proportions of dense calcium (DC), fibrous, fibro fatty (FF), and necrotic core (NC) tissue. Furthermore, the presence of vulnerable plaques, defined by plaque volume and tissue composition, was examined. Coronary plaque volume increased significantly with worsening clinical risk profile [geometric mean (95% confidence interval): 148 (129–166) mm3, 257 (224–295) mm3, and 407 (363–457) mm3, respectively, P < 0.001]. Plaque composition differed significantly across cohorts, P < 0.0001. The proportion of DC decreased, whereas FF and NC increased with worsening clinical risk profile (mean proportions DC: 33%, 23%, 23%; FF: 50%, 61%, 57%; and NC: 17%, 17%, 20%, respectively). Significant differences in plaque composition persisted after multivariable adjustment for age, gender, body surface area, hypertension, statin use at baseline, diabetes, smoking, family history of ischaemic heart disease, total plaque volume, and tube voltage, P < 0.01.
Conclusion
Coronary atherosclerotic plaque volume and composition are strongly associated to clinical presentation.
