Lateral Sclerosis

ObjectivesAmyotrophic lateral sclerosis (ALS) is a rapidly progressive neurodegenerative disorder. Sleep disturbance may interfere with clearance of abnormal proteins that aggregate in neurodegenerative diseases. The objective of this study was to examine the association between benign prostatic hyperplasia (BPH), a common disorder causing nocturia and sleep disturbance, and risk of ALS and other motor neuron disease (MND). We hypothesised that men with BPH, in comparison to men in the general population, would be at increased risk.DesignThis is a nationwide, population-based cohort study.SettingThis study was conducted among the population of Denmark.ParticipantsWe used linked Danish medical databases to identify all men with a first-time diagnosis of BPH between 1 January 1980 and 30 November 2013 and no prior diagnosis of MND (BPH cohort, n=223 131) and an age-matched general population comparison cohort of men without BPH or MND (n=1 115 642).Primary outcome measureThe primary outcome is diagnosis of MND after the BPH diagnosis (index) date, with follow-up until MND diagnosis, emigration, death or 30 November 2013.ResultsWe used Cox regression to compute adjusted HR, comparing men with and without BPH. After 34 years of follow-up, there were 227 cases of MND in the BPH cohort (incidence rate 0.13/1000 person-years) and 1094 MND cases in the comparison cohort (0.12/1000 person-years; HR 1.05, 95% CI 0.90 to 1.22). Risk did not vary by follow-up time.ConclusionsBPH is not associated with an increased risk of ALS and other MND. Future studies should examine the relation between other disorders that disrupt sleep and MND risk in men and women.

ObjectiveTo assess whether metformin use affects risk of benign prostatic hyperplasia (BPH) by comparing the risk of BPH in men with type 2 diabetes who initiated first-line treatment with either metformin or sulfonylurea monotherapy between 2000 or 2006 in Northern Denmark. In this period, sulfonylurea and metformin were both frequently used as first-line glucose-lowering drug (GLD) treatment.DesignA population-based cohort study.SettingNorthern Denmark.ParticipantsAll men who filled at least two prescriptions for metformin or for sulfonylurea, respectively, during their first 6 months of GLD treatment. Follow-up started 6 months after treatment start.Primary outcome measuresRates of subsequent BPH, identified based on community prescriptions for BPH-related treatment or hospital BPH diagnoses, and rates of transurethral resection of the prostate (TURP). Rates in metformin and sulfonylurea users were compared overall and stratified by 6-month haemoglobin A1c (HbA1c) using Cox regression and an intention-to-treat (ITT) approach and an as-treated analysis.ResultsDuring follow-up, less than five persons were lost to follow-up due to emigration. In 3953 metformin initiators with a median follow-up of 10 years, the 10-year cumulative BPH incidence was 25.7% (95% CI 24.2 to 27.1). Compared with 5958 sulfonylurea users (median follow-up 8 years, 10-year cumulative incidence 27.4% (95% CI 26.2 to 28.6)), the crude HR for BPH was 0.83 (95% CI 0.77 to 0.89) and adjusted HR in the ITT analyses was 0.97 (95% CI 0.88 to 1.06). For TURP, the adjusted HR was 0.96 (95% CI 0.63 to 1.46). In the as-treated analysis, adjusted HR for BPH was 0.91 (95% CI 0.81 to 1.02).ConclusionsCompared with sulfonylurea, metformin did not substantially reduce the incidence of BPH in men with diabetes.

Objective Several studies have shown an increased risk for cardiovascular disease (CVD) in hyperthyroidism, but most studies have been too small to address the effect of hyperthyroidism on individual cardiovascular endpoints. Our main aim was to assess the association among hyperthyroidism, acute cardiovascular events and mortality. Design It is a nationwide population-based cohort study. Data were obtained from the Danish Civil Registration System and the Danish National Patient Registry, which covers all Danish hospitals. We compared the rate of all-cause mortality as well as venous thromboembolism (VTE), acute myocardial infarction (AMI), ischemic and non-ischemic stroke, arterial embolism, atrial fibrillation (AF) and percutaneous coronary intervention (PCI) in the two cohorts. Hazard ratios (HR) with 95% confidence intervals (95% CI) were estimated. Results The study included 85 856 hyperthyroid patients and 847 057 matched population-based controls. Mean follow-up time was 9.2 years. The HR for mortality was highest in the first 3 months after diagnosis of hyperthyroidism: 4.62, 95% CI: 4.40–4.85, and remained elevated during long-term follow-up (>3 years) (HR: 1.35, 95% CI: 1.33–1.37). The risk for all examined cardiovascular events was increased, with the highest risk in the first 3 months after hyperthyroidism diagnosis. The 3-month post-diagnosis risk was highest for atrial fibrillation (HR: 7.32, 95% CI: 6.58–8.14) and arterial embolism (HR: 6.08, 95% CI: 4.30–8.61), but the risks of VTE, AMI, ischemic and non-ischemic stroke and PCI were increased also 2- to 3-fold. Conclusions We found an increased risk for all-cause mortality and acute cardiovascular events in patients with hyperthyroidism.

AbstractThe vagus nerve plays an essential role in homeostasis and inflammation. Clinically, peptic ulcer patients without helicobacter pylori (HP) infection may provide a population for studying the effect of vagal hyperactivity. There were interests in the association of gastrointestinal disease and urogenital disorders. Herein, we try to investigate subsequent risk of benign prostatic hyperplasia (BPH) in non-HP infected peptic ulcer patients. We identified 17,672 peptic ulcer admission male patients newly diagnosed in 1998–2007 from Taiwan Health Insurance Database, and 17,672 male comparison without peptic ulcer, frequency matched by age, and index-year. We assessed subsequent incidence of BPH in each cohort by the end of 2013, and then compared the risk of developing BPH between individuals with and without peptic ulcer. In addition, peptic ulcer patients underwent surgery were also examined. There were 2954 peptic ulcer patients and 2291 comparisons noted with the occurrence of BPH (25.35 and 16.70 per 1000 person-years, respectively). Compared to comparisons, peptic ulcer patients had a 1.45- and 1.26-fold BPH risk in multivariable Cox model and Fine and Gray model (95% CI 1.37–1.54 and 1.19–1.34). In age-stratified analysis, the highest risk of BPH was in 45–59 years (interaction p < 0.05). Regarding surgery types, peptic ulcer patients who underwent simple suture surgery (i.e.: with integrated vagus nerve) had a significant higher BPH risk than comparison (HR 1.50 and 95% CI 1.33–1.74; SHR 1.26 and 95% CI 1.07–1.48), while patients underwent truncal vagotomy/pyloroplasty showed a lower incidence of BPH. In this study, non-HP-infected male peptic ulcer patients were found to have an increased risk of subsequent BPH. Indicating that there might be a role of vagus nerve. Based on the limitations of retrospective nature, further studies are required.
