Erectile dysfunction risk among patients with diabetes mellitus using sodium-glucose cotransporter 2 inhibitors.

To explore the incidence of new-onset erectile dysfunction (ED) in diabetes mellitus (DM) patients with sodium-glucose cotransporter 2 inhibitors (SGLT2I) use compared to a control group of non-SGLT2I use by propensity matching (PS) matching approach. Cox proportion hazards regression models were used to examine the effect of SGLT2I and risk factors on the risk of developing ED, presented as a hazard ratio (HR) with a 95% confidence interval (CI). 159773 DM patients using SGLT2I and 159773 PS-matching DM patients who had never used SGLT2I was included. SGLT2I users had a higher risk of ED than the non-SGLT2I users (adjusted HR = 1.55, 95% CI = 1.40-1.72). The likelihood of developing ED was higher in patients with SGLT2I use was found.

Association of antipsychotic drugs on type 2 diabetes mellitus risk in patients with schizophrenia: a population-based cohort and in vitro glucose homeostasis-related gene expression study.

BACKGROUND: Type 2 diabetes mellitus (T2DM) and its related complications are associated with schizophrenia. However, the relationship between antipsychotic medications (APs) and T2DM risk remains unclear. In this population-based, retrospective cohort study across the country, we investigated schizophrenia and the effect of APs on the risk of T2DM, and glucose homeostasis-related gene expression. METHODS: We used information from the Longitudinal Health Insurance Database of Taiwan for individuals newly diagnosed with schizophrenia (N = 4,606) and a disease-free control cohort (N = 4,606). The differences in rates of development of T2DM between the two cohorts were assessed using a Cox proportional hazards regression model. The effects of APs on the expression of glucose homeostasis-related genes in liver and muscle cell lines were assessed using quantitative real-time PCR. RESULTS: After controlling potential associated confounding factors, the risk of T2DM was higher in the case group than that in the control group [adjusted hazard ratio (aHR), 1.80, p < 0.001]. Moreover, the likelihood of T2DM incidence in patients with schizophrenia without AP treatment (aHR, 2.83) was significantly higher than that in non-schizophrenia controls and those treated with APs (aHR ≤ 0.60). In an in vitro model, most APs did not affect the expression of hepatic gluconeogenesis genes but upregulated those beneficial for glucose homeostasis in muscle cells. CONCLUSION: This study demonstrates the impact of schizophrenia and APs and the risk of developing T2DM in Asian populations. Unmeasured confounding risk factors for T2DM may not have been included in the study. These findings may help psychiatric practitioners identify patients at risk of developing T2DM.

Evaluating the risk of new-onset glaucoma in chronic kidney disease patients: a nationwide cohort study.

BACKGROUND: A better understanding of the association between chronic kidney disease (CKD) and glaucoma is required to optimize clinical outcomes. Therefore, this study aimed to investigate the association of chronic kidney disease (CKD) with new diagnoses of glaucoma over time from January 2009 to December 2019. METHOD: This retrospective propensity-matched cohort study utilizing Taiwanese electronic health records examined the incidence of newly diagnosed glaucoma in patients with and without chronic kidney disease (CKD). The exposure variable was the diagnosis of CKD, identified through diagnostic codes. The primary outcome was the incidence of new-onset glaucoma. Subgroup analyses on glaucoma risk included age, gender, comorbidities, glaucoma subtypes, and dialysis status. Statistical analyses included Kaplan-Meier analysis, Cox proportional hazards models, and Poisson regression models, with the associated hazard ratios and confidence intervals reported. RESULTS: Seven hundred twenty-three thousand two hundred sixteen patients with CKD (42.3% female; mean [SD] age at index, 66.3 [15.6] years) and 723,216 patients without CKD (42.3% female; mean [SD] age at index, 66.3 [15.7]) were recruited. We showed a significantly increased risk of glaucoma irrespective of subtypes in CKD patients compared to those without CKD (HR: 1.29 [CI: 1.26-1.32], p < 0.001). Kaplan-Meier curves revealed a significantly increased glaucoma risk in both the dialytic subtype and non-dialytic CKD patients when compared to their non-CKD counterparts (p < 0.001). We also showed that all genders (aHR 1.17 [CI: 1.13-1.21] for females vs. aHR 1.39 [CI:1.35-1.43] for males), all ages (< = 49: aHR 1.49 [CI: 1.37-1.62]; 50-59: aHR 1.48 [CI: 1.40-1.56]; 60-69: aHR 1.30 [CI: 1.25-1.6]; 70-79: aHR 1.21 [CI: 1.17-1.26]; > 80: aHR 1.29 [CI: 1.21-1.37]); all income brackets and all urbanization status were associated with significantly increased risk of glaucoma from among the CKD cohort when compared to their respective non-CKD cohort (p < 0.001). CONCLUSIONS: Our cohort study spanning 12 years showed an elevated glaucoma risk following a CKD diagnosis compared to a frequency-matched non-CKD cohort. Our findings have relevance for the clinical practice of at-risk CKD patients. TRIAL REGISTRATION: Due to the retrospective nature of the study, no registration was necessary.

Dual Caregiving and Mental Health Among Long-Term Care Nursing Assistants: The Moderating Role of Social Support.

AIM: To investigate the association of long-term care nursing assistants' dual caregiving roles with mental health and to determine whether social support moderates this relationship. DESIGN: A cross-sectional survey. METHODS: We surveyed 962 certified long-term care nursing assistants working in long-term care and medical facilities across Taiwan from October 2022 to July 2023. 'Dual caregiving roles' denote the fulfilment of caregiving duties both at work and within families. Mental health was evaluated using the 5-item Brief Symptom Rating Scale. Logistic regression analysis was utilized to investigate the association of dual caregiving roles and psychological job demands with poor mental health. Moreover, we explored whether family, colleague, and supervisor support moderated the association between dual caregiving roles and poor mental health. RESULTS: Among long-term care nursing assistants, 15% had dual caregiving responsibilities. Individuals with both dual caregiving roles and high psychological job demands faced the highest risk of poor mental health compared to those without dual caregiving roles and low psychological job demands. Having dual caregiving roles was associated with poor mental health compared to workers without such roles. Additionally, support from family, colleagues, and supervisors mitigates the association between caregivers' dual caregiving roles and poor mental health. CONCLUSION: A substantial proportion of long-term care nursing assistants had dual caregiving roles, leading to an additional mental health burden when combined with high psychological job demands. High social support attenuated this association. IMPLICATIONS FOR THE PROFESSION: Long-term care nursing assistants with dual caregiving roles had poorer mental health outcomes. Yet, support from family, colleagues, and supervisors mitigated these effects. These results emphasize the importance of enhancing social support to protect the mental well-being of long-term care nursing assistants managing both formal and informal caregiving duties. REPORTING METHOD: This study adheres to the STROBE guideline of reporting. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

Integrating traditional Chinese Medicine reduced the risk of hip fracture in patients with dementia.

BACKGROUND/PURPOSE: The high incidence of hip fracture is an important problem among dementia patients because of their higher risk of falls and balance deficits due to a lack of physical activity. The aim of this study was to investigate whether traditional Chinese medicine (TCM) therapy could reduce the risk of hip fracture in dementia patients. METHODS: We identified 38,071 patients who were first diagnosed with dementia from January 1, 2000, to December 31, 2017, from the database of the 2000 Longitudinal Generation Tracking Database (LGTD 2000) provided by the Health and Welfare Data Science Center (HWDC) in Taiwan. Patients who received TCM treatment after the initial diagnosis of dementia were assigned to the TCM group, and patients who never received TCM treatment were assigned to the non-TCM group. After performing 1:1 propensity score matching (1:1) based on age, sex, comorbidities and medication between the TCM and non-TCM groups, there were 902 patients in each group. Patients were followed up to December 31, 2018, and incidences of hip fracture after the initial diagnosis of dementia between the two groups were compared with Cox regression analysis. RESULTS: Ninety-four patients in the non-TCM group (10.42%) and 58 patients in the TCM group (6.43%) suffered from hip fracture during the follow-up period. Patients in the TCM group had a lower incidence of hip fracture than those in the non-TCM group (adjusted hazard ratio = 0.54, 95% confidence interval = 0.38-0.76). CONCLUSIONS: Integrating TCM health care for dementia patients might reduce the risk of hip fracture.

Acute mountain sickness on Jade Mountain: Results from the real-world practice (2018-2019).

Acute mountain sickness (AMS) is initiated in response to a hypoxic and hypobaric environment at a high altitude. The precise prevalence of AMS in Jade Mountain climbers remained largely unknown, particularly data obtained from real medical consultations. An overnight stay at the Pai-Yun Lodge (3402 m) is usually required before an ascent of the Jade Mountain. Since 2004, a Pai-Yun Clinic has been established in the Pai-Yun Lodge. The Pai-Yun Clinic provided regular and emergency medical service every weekend. We conducted a retrospective study by using medical records from the Pai-Yun Clinic between 2018 and 2019. A total of 1021 patients were enrolled, with 56.2 % males. Different age groups were 3.2 %, 54.5 %, 37.9 %, and 4.4 % in <20, 20-39, 40-59, and ≥60 years, respectively. There were 582 (57.0 %) patients diagnosed to have AMS (230 [39.5 %] were mild type and 352 [60.5 %] were severe type). The factors associated with AMS development included young age, absence of climbing history (>3000 m) within the last 3 months, first climbing (>3000 m) experience, taking preventive medication, low oxygen saturation, and a high Lake Louise AMS score (LLAMSS). The factors associated with AMS severity included absence of taking preventive medication, low oxygen saturation, and a high LLAMSS. Approximately 15 % of Jade Mountain climbers needed medical service, of which 60 % had AMS. 60 % of patients with AMS must require oxygen supply or medication prescription. Oxygen saturation measure and LLAMSS evaluation are reasonable tools to predict the occurrence and severity of AMS on Jade Mountain.

Reduced mortality in patients with extended duration of methadone maintenance treatment: a five-year retrospective nationwide study.

BACKGROUND: The retention of patients under methadone maintenance treatment (MMT) is an indication for the effectiveness of the therapy. We aimed to explore the relation between mortality and the cumulative MMT duration. METHODS: A retrospective cohort analysis was performed using Taiwan Illicit Drug Issue Database (TIDID) and National Health Insurance Research Database (NHIRD) during 2012-2016. We included 9149 and 11 112 MMT patients as the short and long groups according to the length of their cumulative MMT duration, 1-364 and ⩾365 days, respectively. The risk of mortality was calculated by Cox proportional hazards regression model with time-dependent exposure to MMT, and the survival probability was plotted with the Kaplan-Meier curve. RESULTS: The mortality rates were 2.51 and 1.51 per 100 person-years in the short and long cumulative MMT duration groups, respectively. After adjusting for on or off MMT, age, sex, marital status, education level, maximum methadone dose, and comorbidities (human immunodeficiency virus, depression, hepatitis C virus, hepatitis B virus, alcoholic liver disease, and cardiovascular disease), the long group had a lower risk of death (hazard ratio = 0.67; 95% confidence interval 0.60-0.75) than the short group. Increased risk was observed in patients with advanced age, being male, unmarried, infected by HIV, HCV, and HBV, and diagnosed with depression, ALD, and CVD. Causes of death were frequently related to drug and injury. CONCLUSIONS: Longer cumulative MMT duration is associated with lower all-cause and drug-related mortality rate.

Risk Factors of Dementia in Patients with Cerebral Vascular Diseases Based on Taiwan National Health Insurance Data.

INTRODUCTION: Vascular factors have been shown to be associated with increased risk of dementia. However, clinical trials have so far been unsuccessful, suggesting new approaches are needed. The aim of this study was to use population-based real-world data to investigate risk factors and preventive factors for dementia, including the effects of traditional Chinese medicine (TCM). METHODS: This is a retrospective cohort study using LHID2000, a dataset randomly selected from Taiwan's National Health Insurance Research Database. Subjects with occlusion and stenosis of precerebral and cerebral arteries, cerebral atherosclerosis without mention of cerebral infarction, and transient cerebral ischemia were included. Subjects with dementia at baseline were excluded. The primary endpoint was dementia. Data for demographic and clinical comorbid status and treatments administered at baseline in 2000 and at the end of follow-up in 2013 were included. RESULTS: A total of 4,207 subjects with cerebral vascular disease and no cognitive impairment were included, of whom 392 converted to dementia during an average 5.15-year (SD: 3.79) follow-up. Depression (adjusted HR: 1.54, 95% confidence interval [CI]: 1.13-2.09), osteoporosis (adjusted HR: 1.34, 95% CI: 1.04-1.74), and the use of enalapril (adjusted HR: 1.37, 95% CI: 1.09-1.73) were risk factors for dementia, while nitroglycerin (adjusted HR: 0.67, 95% CI: 0.53-0.85) was a protecting factor, in subjects with cerebrovascular diseases without mention of cerebral infarction. In total, statins were shown to be associated with decreased risk of dementia (HR: 0.73, 95% CI: 0.59-0.91); however, no one statin subtype or TCM had such an effect. CONCLUSION: Depression, osteoporosis, and the use of enalapril were associated with a higher risk of dementia, while nitroglycerin might be a protecting factor for dementia, in subjects with cerebrovascular diseases without mention of cerebral infarction.

Angiotensin Receptor-neprilysin Inhibitor Versus Renin-angiotensin System Inhibitor for Dementia Risk in Patients With Heart Failure.

ABSTRACT: The authors report the impact of angiotensin receptor-neprilysin inhibitor (ARNI) versus renin-angiotensin system inhibitor (RASI) on the management and outcomes in dementia among heart failure (HF) patients as obtained from the real-life nationwide registry. In this study, HF patients between January 1, 2017 and December 31, 2019 were divided into 2 groups, including subjects receiving RASI and ARNI. The incidence rate of dementia was calculated with the unit of 1000 person-years. Cox proportional hazard model was applied for the examination of the hazard ratio, and also presented with 95% confidence interval. Between 2017 and 2019, RASI and ARNI cohorts contain 18,154 subjects. After adjusting with age, sex, comorbidities, and medications, ARNI cohort had a lower risk of dementia (adjusted hazard ratio = 0.83; 95% confidence interval = 0.72, 0.95) than RASI cohort. The authors concluded that use of ARNI was associated with a lower risk of new-onset dementia in patients with HF.

Association of Heart Failure Patients With and Without Sacubitril-Valsartan Use With Incident Cancer Risk.

ABSTRACT: This study was to evaluate the association between heart failure (HF) patients with and without sacubitril-valsartan use with incident cancer risk. This study consisted of 18,072 patients receiving sacubitril-valsartan and 18,072 control group participants. In the Fine and Gray model, which extends the standard Cox proportional hazards regression model, we estimated the relative risk of developing cancer between the sacubitril-valsartan cohort and the non-sacubitril-valsartan cohort by using subhazard ratios (SHRs) and 95% confidence intervals (CIs). The incidence rates of cancer were 12.02 per 1000 person-years for the sacubitril-valsartan cohort and 23.31 per 1000 person-years for the non-sacubitril-valsartan cohort. Patients receiving sacubitril-valsartan had a significantly lower risk of developing cancer with an adjusted SHR of 0.60 (0.51, 0.71). Sacubitril-valsartan users were less to be associated with the development of cancer.

Long-term exposure to air pollution and risk of Sarcopenia in adult residents of Taiwan: a nationwide retrospective cohort study.

BACKGROUND: Sarcopenia is an age-related, multifactorial syndrome. Previous studies have shown that air pollutants are associated with inflammation and oxidative stress. However, the association between long-term exposure to air pollution and sarcopenia is not completely understood. METHODS: The Taiwan National Health Research Database (NHIRD) contains medical records of almost all Taiwanese residents. Daily air pollution data collected by the Taiwan Environmental Protection Agency was used to analyze concentrations of sulfur oxide (SO2), carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO2), and particulate matter (PM2.5, PM10). The databases were merged according to the insurants' living area and the location of the air quality monitoring station. We categorized the pollutants into quartiles (Q1, Q2, Q3, and Q4). RESULTS: Our study population consisted of 286,044 patients, among whom 54.9% were female and 45.1% were male. Compared to Q1 levels of pollutants, Q4 levels of SO2 (adjusted hazard ratio [aHR] = 8.43; 95% confidence interval [CI] = 7.84, 9.07); CO (aHR = 3.03; 95%CI = 2.83, 3.25); NO (aHR = 3.47; 95%CI = 3.23, 3.73); NO2 (aHR = 3.72; 95%CI = 3.48, 3.98); PM2.5 (aHR = 21.9; 95% CI = 19.7, 24.5) and PM10 (aHR = 15.6; 95%CI = 14.1, 17.4) increased risk of sarcopenia. CONCLUSIONS: Our findings indicated a significantly increased risk of sarcopenia in both male and female residents exposed to high levels of air pollutants.

Comparisons of HATCH, HAVOC and CHA2DS2-VASc scores for all-cause mortality prediction in atrial fibrillation: a real-world evidence study.

OBJECTIVE: This study focused on the predictive ability of the 3 scores for all-cause mortality in 6444 patients with atrial fibrillation (AF). METHODS: To assess the predictive accuracy of risk of death modelled by HATCH, HAVOC and CHA2DS2-VASc scores, the area under the curve of receiver operating characteristics (AUROC) was applied. RESULTS: Over follow-up time, the cumulative incidence of death was clearly associated with the three scores (log-rank test, p<0.001). The AUROC for the HATCH (0.6618) was significantly higher than HAVOC Score (0.5733) and CHA2DS2-VAScs Score (0.6423). CONCLUSIONS: HATCH score has better ability in predicting mortality in comparison to other two scores in patients with AF.

Using progression in adapted diabetes complications severity index score to predict erectile dysfunction in men affected by type 2 diabetes mellitus.

OBJECTIVE: This study is on the use of the adapted Diabetes Complications Severity Index (aDCSI) for erectile dysfunction (ED) risk stratification in male patients with type 2 diabetes mellitus (DM). METHODS: This is a retrospective study with records obtained from Taiwan's National Health Insurance Research Database. Adjusted HRs (aHRs) were estimated by multivariate Cox proportional hazards models with 95% confidence intervals (CIs).. RESULTS: A population of 84 288 eligible male patients with type 2 DM were included. Compared with change in aDCSI score of 0.0-0.5 per year, the aHRs and the corresponding 95% CIs for other changes in aDCSI scores are summarised as follows: 1.10 (0.90 to 1.34) for change in aDCSI score of 0.5-1.0 per year; 4.44 (3.47 to 5.69) for change in aDCSI score of 1.0-2.0 per year; and 10.9 (7.47 to 15.9) for change in aDCSI score of >2.0 per year.. CONCLUSIONS: Progression in aDCSI score might be used for ED risk stratification in men affected by type 2 DM.

Weekend versus weekday hospitalization and clinical outcomes in atrial fibrillation patients with and without stroke.

PURPOSE: The relation between hospitalization timing and risk of clinical outcomes among patients with atrial fibrillation (AF) with and without stroke remained undetermined. METHODS: Rehospitalization due to AF, cardiovascular (CV) death and all-cause mortality were the outcomes of interest in this study. Multivariable Cox proportional hazard model was applied to estimate the adjusted hazard ratio (HR) and 95% confidence interval (CI). RESULTS: While considering patients with AF hospitalized during weekdays without stroke as the reference group, patients with AF hospitalized during weekends with stroke had the risk of AF rehospitalization, CV death and all-cause death by 1.48 (95% CI 1.44 to 1.51), 1.77 (95% CI 1.71 to 1.83) and 1.17 (95% CI 1.15 to 1.19) times, respectively. CONCLUSION: Patients with AF hospitalized during weekends with stroke had the worst clinical outcomes.

Patient and hospital characteristics associated with do-not-resuscitate/do-not-intubate orders: a cross-sectional study based on the Taiwan stroke registry.

BACKGROUND: Previous studies of do-not-resuscitate (DNR) or do-not-intubate (DNI) orders in stroke patients have primarily been conducted in North America or Europe. However, characteristics associated with DNR/DNI orders in stroke patients in Asia have not been reported. METHODS: Based on the Taiwan Stroke Registry, this nationwide cross-sectional study enrolled hospitalized stroke patients from 64 hospitals between 2006 and 2020. We identified characteristics associated with DNR/DNI orders using a two-level random effects model. RESULTS: Among the 114,825 patients, 5531 (4.82%) had DNR/DNI orders. Patients with acute ischemic stroke (AIS) had the highest likelihood of having DNR/DNI orders (adjusted odds ratio [aOR] 1.76, 95% confidence interval [CI] 1.61-1.93), followed by patients with intracerebral hemorrhage (ICH), and patients with subarachnoid hemorrhage (SAH) had the lowest likelihood (aOR 0.53, 95% CI 0.43-0.66). From 2006 to 2020, DNR/DNI orders increased in all three types of stroke. In patients with AIS, women were significantly more likely to have DNR/DNI orders (aOR 1.23, 95% CI 1.15-1.32), while patients who received intravenous alteplase had a lower likelihood (aOR 0.74, 95% CI 0.65-0.84). Patients with AIS who were cared for by religious hospitals (aOR 0.55, 95% CI 0.35-0.87) and patients with SAH who were cared for by medical centers (aOR 0.40, 95% CI 0.17-0.96) were significantly less likely to have DNR/DNI orders. CONCLUSIONS: In Taiwan, DNR/DNI orders increased in stroke patients between 2006 and 2020. Hospital characteristics were found to play a significant role in the use of DNR/DNI orders.

How mycobacterium tuberculosis infection could lead to the increasing risks of chronic fatigue syndrome and the potential immunological effects: a population-based retrospective cohort study.

BACKGROUND: Chronic fatigue syndrome (CFS) has been shown to be associated with infections. Tuberculosis (TB) is a highly prevalent infectious disease. Patients with chronic fatigue syndrome and post-tuberculosis experience similar symptoms. Furthermore, chronic fatigue syndrome and tuberculosis share similar plasma immunosignatures. This study aimed to clarify the risk of chronic fatigue syndrome following the diagnosis of Mycobacterium tuberculosis infection (MTI), by analyzing the National Health Insurance Research Database of Taiwan. METHODS: 7666 patients aged 20 years or older with newly diagnosed Mycobacterium tuberculosis infection during 2000-2011 and 30,663 participants without Mycobacterium tuberculosis infection were identified. Both groups were followed up until the diagnoses of chronic fatigue syndrome were made at the end of 2011. RESULTS: The relationship between Mycobacterium tuberculosis infection and the subsequent risk of chronic fatigue syndrome was estimated through Cox proportional hazards regression analysis, with the incidence density rates being 3.04 and 3.69 per 1000 person-years among the non-Mycobacterium tuberculosis infection and Mycobacterium tuberculosis infection populations, respectively (adjusted hazard ratio [HR] = 1.23, with 95% confidence interval [CI] 1.03-1.47). In the stratified analysis, the Mycobacterium tuberculosis infection group were consistently associated with a higher risk of chronic fatigue syndrome in the male sex (HR = 1.27, 95% CI 1.02-1.58) and age group of ≥ 65 years old (HR = 2.50, 95% CI 1.86-3.38). CONCLUSIONS: The data from this population-based retrospective cohort study revealed that Mycobacterium tuberculosis infection is associated with an elevated risk of subsequent chronic fatigue syndrome.

Risks of central nervous system infections and related mortality in patients undergoing dialysis.

INTRODUCTION: This study aimed to investigate the risks of central nervous system (CNS) infections and related mortality in patients with end-stage renal disease (ESRD) undergoing dialysis. METHODS: Incident dialysis patients were identified from 2000 to 2013. The risks of CNS infection and related mortality were analyzed. RESULTS: The adjusted hazard ratio (HR) of CNS infection in the ESRD group compared with the control group was 3.46 (95% confidence interval [CI] 2.75-4.35). The adjusted odds ratio (OR) of 90-day mortality following CNS infections in the ESRD group in comparison with the control group was 5.99 (95% CI 2.78-12.9). The adjusted HR of overall CNS infection for the peritoneal dialysis (PD) group in comparison with the hemodialysis (HD) group was 1.07 (95% CI 0.63-1.82). Influenza vaccination was associated with a lower risks of CNS infection in dialysis patients (adjusted HR: 0.38, 95% CI 0.30-0.48). The adjusted OR of 90-day mortality following CNS infection for the PD group in comparison with the HD group was 1.01 (95% CI 0.55-1.87). CONCLUSIONS: The risks of CNS infections and related mortality were remarkably high in dialysis patients with no significant difference between patients with ESRD under HD and PD treatment.

Association of alpha-1-adrenergic antagonist use with the risk of gout development in benign prostatic hyperplasia patients: a population-based cohort study.

BACKGROUND: Men are more likely to develop benign prostatic hyperplasia (BPH) and gout as they age. However, the role of alpha-1-adrenergic antagonists, the medication for BPH, in the development of gout is uncertain. OBJECTIVE: To investigate the effect of alpha-1-adrenergic antagonist use on the risk of developing gout in BPH patients. METHODS: Data of patients with newly diagnosed BPH were retrieved from Taiwan's 2000-2013 National Health Insurance Research Database (total number: 15,390 patients; 7,695 patients in each cohort). Propensity score matching was conducted according to age, comorbidities, medication history for cohorts that received or did not receive alpha-1-adrenergic antagonists. Hazard ratios (HRs) were assessed for gout development using Cox proportional hazards regression models. RESULTS: Use of alpha-1-adrenergic antagonists was not associated with gout development in BPH patients (HR = 0.92; 95% confidence interval [CI], 0.78-1.10; P = 0.35). However, after stratification according to the average number of days of alpha-1-adrenergic antagonist use per year, patients with an average of >300 days had a significantly higher risk of gout development than patients who did not receive alpha-1-adrenergic antagonists (adjusted HR = 1.57; 95% CI, 1.25-1.97; P < 0.001). Patients with more days of medication use per year had a higher risk of gout development than those with fewer days of medication use (P < 0.001). CONCLUSION: Patients who received more doses of alpha-1-adrenergic antagonists per year had a higher risk of developing gout. A causal proof of the role of alpha-1-adrenergic antagonists use in gout development should be analysed in future studies designed as double blind randomized controlled trials.

Effect of anticoagulant/antiplatelet therapy on the development and progression of diabetic retinopathy.

BACKGROUND: We investigated whether antiplatelet/anticoagulant (APAC) therapy can protect patients with type 2 diabetes mellitus (T2DM) from the development or progression of diabetic retinopathy (DR). METHODS: This is a retrospective cohort study using Longitudinal Health Insurance Database in Taiwan. A total of 73,964 type 2 diabetic patients older than 20 years old were included. Hazard ration (HR) of non-proliferative DR (NPDR), proliferative DR (PDR), and diabetic macular edema (DME) were analyzed with APAC usage as a time-dependent covariate. Age, sex, comorbidities, and medicines were further adjusted in a multi-variable model. Contributions of respective APAC was investigated with sensitivity analysis. RESULTS: Compared with nonusers, APAC users had a lower cumulative incidence of NPDR (P < 0.001), overall incidence of NPDR (10.7 per 1000 person-years), and risk of developing NPDR (adjusted HR = 0.78, 95% CI = 0.73-0.83). However, no significant differences were observed between APAC users and nonusers in the risks of PDR or DME. Hypertension, diabetic nephropathy and diabetic neuropathy were risk factors for NDPR development, while heart disease, cardiovascular disease, peripheral arterial occlusive disease, and statin usage were covariates decreasing NPDR development. Aspirin and Dipyridamole showed significant protection against NPDR development. Clopidogrel, Ticlopidine, and warfarin showed enhanced protection in combination with aspirin usage. CONCLUSIONS: APAC medications have a protective effect against NPDR development. Diabetic patients benefit from single use of aspirin or dipyridamole on prevention of NPDR.

ProDisc-C versus anterior cervical discectomy and fusion for the surgical treatment of symptomatic cervical disc disease: two-year outcomes of Asian prospective randomized controlled multicentre study.

PURPOSE: Our study aimed to evaluate non-inferiority of ProDisc-C to anterior cervical discectomy and fusion (ACDF) in terms of clinical outcomes and incidence of adjacent segment disease (ASD) at 24-months post-surgery in Asian patients with symptomatic cervical disc disease (SCDD). METHODS: This multicentre, prospective, randomized controlled trial was initiated after ethics committee approval at nine centres (China/Hong Kong/Korea/Singapore/Taiwan). Patients with single-level SCDD involving C3-C7-vertebral segments were randomized (2:1) into: group-A treated with ProDisc-C and group-B with ACDF. Assessments were conducted at baseline, 6-weeks, 3/6/12/18/24-months post-surgery and annually thereafter till 84-months. Primary endpoint was overall success at 24-months, defined as composite of: (1) ≥ 20% improvement in neck disability index (NDI); (2) maintained/improved neurologic parameters; (3) no implant removal/revision/re-operation at index level; and (4) no adverse/severe/life-threatening events. RESULTS: Of 120 patients (80ProDisc-C,40ACDF), 76 and 37 were treated as per protocol (PP). Overall success (PP) was 76.5% in group-A and 81.8% in group-B at 24-months (p = 0.12), indicating no clear non-inferiority of ProDisc-C to ACDF. Secondary outcomes improved for both groups with no significant inter-group differences. Occurrence of ASD was higher in group-B with no significant between-group differences. Range of motion (ROM) was sustained with ProDisc-C but lost with ACDF at 24-months. CONCLUSION: Cervical TDR with ProDisc-C is feasible, safe, and effective for treatment of SCDD in Asians. No clear non-inferiority was demonstrated between ProDisc-C and ACDF. However, patients treated with ProDisc-C demonstrated significant improvement in NDI, neurologic success, pain scores, and 36-item-short-form survey, along with ROM preservation at 24-months. Enrolment difficulties resulted in inability to achieve pre-planned sample size to prove non-inferiority. Future Asian-focused, large-scale studies are needed to establish unbiased efficacy of ProDisc-C to ACDF.
