Primary aldosteronism is associated with risk of urinary bladder stones in a nationwide cohort study

AbstractWe analyzed database from the Taiwan National Health Insurance to investigate whether primary aldosteronism (PA) increases the risk of bladder stones. This retrospective nationwide population-based cohort study during the period of 1998–2011 compared patients with and without PA extracted by propensity score matching. Cox proportional hazard models and competing death risk model were used to estimate the hazard ratios (HRs), sub-hazard ratios (SHRs) and corresponding 95% confidence intervals (CIs). There were 3442 patients with PA and 3442 patients without PA. The incidence rate of bladder stones was 5.36 and 3.76 per 1000 person-years for both groups, respectively. In adjusted Cox hazard proportional regression models, the HR of bladder stones was 1.68 (95% CI 1.20–2.34) for patients with PA compared to individuals without PA. Considering the competing risk of death, the SHR of bladder stones still indicates a higher risk for PA than a comparison cohort (SHR, 1.79; 95% CI 1.30–2.44). PA, age, sex, and fracture number were the variables significantly contributing to the formation of bladder stones. In conclusion, PA is significantly associated with risk of bladder stones.

Abstract High dietary fiber intake has been associated with a lower risk of diabetes, but the association of dietary fiber with prediabetes is only speculative, especially in China, where the supportive data from prospective studies is lacking. This study aimed to examine the association between dietary fiber intake and risk of incident prediabetes among Chinese adults. We performed a prospective analysis in 18,085 participants of the TCLSIH cohort study who were free of diabetes, prediabetes, cancer, and cardiovascular disease at baseline. Dietary data were collected using a validated 100-item food frequency questionnaire. Prediabetes was defined based on the American Diabetes Association diagnostic criteria. Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). During 63,175 person-years of follow-up, 4,139 cases of incident prediabetes occurred. The multivariable HRs (95% CIs) of prediabetes for the highest versus lowest quartiles were 0.85 (0.75, 0.98) (P for trend =0.02) for total dietary fiber, 0.84 (0.74, 0.95) (P for trend <0.01) for soluble fiber, and 1.05 (0.93, 1.19) (P for trend =0.38) for insoluble fiber. Fiber from fruits, but not from cereals, beans, and vegetables was inversely associated with prediabetes. Our results indicate that intakes of total dietary fiber, soluble fiber, and fiber derived from fruit sources were associated with a lower risk of prediabetes.

Abstract Background Colorectal cancer (CRC) is the most diagnosed cancer among males and third among females in Saudi Arabia, with up to two-third diagnosed at advanced stage. The objective of our study was to estimate CRC survival and determine prognostic factors. Methods Ministry of National Guard- Health Affairs (MNG-HA) registry data was utilized to identify patients diagnosed with CRC between 2009 and 2017. Cases were followed until December 30th, 2017 to assess their one-, three-, and five-year CRC-specific survivals. Kaplan-Meier method and Cox proportional hazard models were used to assess survival from CRC. Results A total of 1012 CRC patients were diagnosed during 2009–2017. Nearly, one-fourth of the patients presented with rectal tumor, 42.89% with left colon and 33.41% of the cases were diagnosed at distant metastasis stage. The overall one-, three-, and five-year survival were 83, 65 and 52.0%, respectively. The five-year survival was 79.85% for localized stage, 63.25% for regional stage and 20.31% for distant metastasis. Multivariate analyses showed that age, diagnosis period, stage, nationality, basis of diagnosis, morphology and location of tumor were associated with survival. Conclusions Findings reveal poor survival compared to Surveillance, Epidemiology, and End Results (SEER) population. Diagnoses at late stage and no surgical and/or perioperative chemotherapy were associated with increased risk of death. Population-based screening in this population should be considered.

Objective: Obesity is an established risk factor for hypertension (HT), but it is still controversial which obesity-related indicator is superior in predictability. This study compared the predictability among three indicators, body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR), in the population-based prospective cohort study of Japan, the Suita study. Methods: Participants who had no HT at baseline (1,591 men and 1,973 women) aged 30-84 years were included in this study. The Cox proportional hazard model was used to estimate hazard ratios (HRs) of each indicator for incident HT with the adjustment for age, cigarette smoking and alcohol drinking. Harrell’s C statistics were also estimated for comparison of indicators’ accuracy. Results: During median follow-up of 7.2 years, 1,325 participants (640 men and 685 women) developed HT. HR (95% CI) of BMI, WC and WHtR for incident HT corresponding to a 1 SD increase was 1.25 (1.15-1.35), 1.21 (1.12-1.31) and 1.23 (1.14-1.34) in men while 1.32 (1.22-1.42), 1.27 (1.18-1.37) and 1.32 (1.21-1.44) in women, respectively. Also, C-statistic (95% CI) of BMI, WC and WHtR was 0.64 (0.62-0.66), 0.63 (0.61-0.65) and 0.63 (0.61-0.66) in men while 0.69 (0.67-0.71), 0.69 (0.67-0.71) and 0.69 (0.67-0.71) in women, respectively. Using 95% CI of each C-statistics, there were no statistical differences among three indicators in both men and women. Conclusion: In this study, we showed that all three indicators (BMI, WC and WHtR) were estimated similarly to predict the risk of developing HT in both Japanese men and women.

Abstract Background Cryptococcal meningitis is a major cause of death among people living with HIV (PLWH). Cryptococcal antigen (CrAg) testing of asymptomatic patients is an important public health measure to reduce mortality in high incidence areas. However, limited data exists on CrAg prevalence in Central America. Methods We conducted a prospective cohort study at the two largest HIV clinics and hospitals in Honduras. CrAg in serum and cerebrospinal fluid was performed in individuals living with HIV who had CD4 ≤ 100 cells/mm 3 between 2017-2018. After CrAg testing, individuals were followed up for 12 months to assess mortality using adjusted cox proportional hazard models. Results A total of 220 PLWH were tested for CrAg of which 12.7% (n=28) tested positive. CrAg prevalence was higher among hospitalized individuals in 40% (n=10 of 25) of the cases. The proportion (35.8%) of individuals taking ART was significantly (p<0.01) lower among those who tested positive for CrAg. Overall mortality among the cohort was 11.4% (n=25 of 220) by 12 months. CrAg-positive cases were at a significantly higher risk of death [aHR: 2.69, 95%: 1.07-6.84] when compared to CrAg-negative participants. Conclusions CrAg prevalence in Honduras was high among PLWH. Moreover, individuals who tested positive for CrAg testing were at a higher risk of death. Systemic CrAg of PLWH with a CD4 ≤ 100 cells/mm 3 should be routinely performed in Central America.

ObjectivesTo examine the temporal trends in mortality and heart failure (HF) hospitalisation in ambulatory patients following a new diagnosis of HF.DesignRetrospective cohort studySettingOutpatientParticipantsOntario residents who were diagnosed with HF in an outpatient setting between 1994 and 2013.Primary and secondary outcome measuresThe primary outcome was all-cause mortality within 1 year of diagnosis and the secondary outcome was HF hospitalisation within 1 year. Risks of mortality and hospitalisation were calculated using the Kaplan-Meier method and the relative hazard of death was assessed using multivariable Cox proportional hazard models.ResultsA total of 352 329 patients were studied (50% female). During the study period, there was a greater decline in age standardised 1-year mortality rates (AMR) in men (33%) than in women (19%). Specifically, female AMR at 1 year was 10.4% (95% CI 9.1% to 12.0%) in 1994 and 8.5% (95% CI 7.5% to 9.5%) in 2013, and male AMR at 1 year was 12.3% (95% CI 11.1% to 13.7%) in 1994 and 8.3% (95% CI 7.5% to 9.1%) in 2013. Conversely, age standardised HF hospitalisation rates declined in men (11.4% (95% CI 10.1% to 12.9%) in 1994 and 9.1% (95% CI 8.2% to 10.1%) in 2013) but remained unchanged in women (9.7% (95% CI 8.3% to 11.3%) in 1994 and 9.8% (95% CI 8.6% to 11.0%) in 2013).ConclusionAmong patients with HF over a 20-year period, there was a greater improvement in the prognosis of men compared with women. Further research should focus on the determinants of this disparity and ways to reduce this gap in outcomes.

Abstract Background Whether or not the use of metformin decreases the risk of gastric adenocarcinoma is unclear. Methods This was a population-based cohort study in 2005–2015. Associations between metformin use and gastric non-cardia and cardia adenocarcinomas were examined within two cohorts; a diabetes cohort of participants using anti-diabetes medications, and a matched cohort of common-medication users, where metformin non-users were frequency matched (10:1) with metformin users for sex and age. Multivariable Cox proportional hazard regression analyses provided hazard ratios (HR) and 95% confidence intervals (CI), adjusting for sex, age, calendar year, comorbidity, Helicobacter pylori eradication treatment, use of non-steroidal anti-inflammatory drugs or aspirin and use of statins. Results During the follow-up for a median of 5.8 years, 892 (0.1%) participants in the diabetes cohort and 6395 (0.1%) participants in the matched cohort of common-medication users developed gastric adenocarcinoma. Metformin users had no significantly decreased risk of gastric non-cardia adenocarcinoma (diabetes cohort: HR 0.93, 95% CI 0.78–1.12; matched cohort: HR 1.30, 95% CI 1.18–1.42) or cardia adenocarcinoma (diabetes cohort: HR 1.49, 95% CI 1.09–2.02; matched cohort: HR 1.58, 95% CI 1.38–1.81) compared with non-users in both cohorts. Conclusions This cohort study with <10 years of follow-up suggests metformin use may not prevent gastric adenocarcinoma.

Background In real-world practice settings, there is insufficient evidence on the efficacy of antiplatelet drugs, including clopidogrel, aspirin, and ticlopidine, in stroke prevention. Purpose To compare the efficacies between aspirin and clopidogrel and aspirin and ticlopidine in stroke prevention. Methods This population-based case-cohort study utilized the data obtained from a randomized sample of one million subjects in the Taiwan National Health Insurance Research Database. Patients who were hospitalized owing to the primary diagnosis of ischemic stroke from January 1, 2000 to December 31, 2010 and treated with aspirin, ticlopidine, or clopidogrel were included in the study. Propensity score matching with a 1:4 ratio was performed to compare aspirin with ticlopidine and clopidogrel. The criteria for inclusion were the use of one of the three antiplatelet drugs for more than 14 days within the first month after the stroke and then continued use of the antiplatelet drugs until the study endpoint of recurrent stroke. Results During the 3-year follow-up period, the recurrent stroke rates were 1.62% (42/2585), 1.48% (3/203), and 2.55% (8/314) in the aspirin, ticlopidine, and clopidogrel groups, respectively. Compared with the patients treated with aspirin, those treated with clopidogrel and ticlopidine showed competing risk-adjusted hazard ratios of recurrent stroke of 2.27 (1.02–5.07) and 0.62 (0.08–4.86), respectively. Conclusion Compared with the patients treated with aspirin, those treated with clopidogrel were at a higher risk of recurrent stroke. For stroke prevention, aspirin was superior to clopidogrel whereas ticlopidine was not inferior to aspirin.

Abstract Background: Flavor sensation was the joint perception of smell and taste sensation was associated with the pleasure of life. Obstructive sleep apnea (OSA) had been demonstrated the presence of upper airway remodeling which altered sensory and motor function due to hypoxia or snore vibration. This study aims to investigate whether OSA is associated with the risk of flavor disorder (FD). Methods: We conducted a nationwide cohort study using the Taiwan National Health Insurance Research Database, one million subjects were sampled with data collected from 1999 to 2013 and 9,191 identified diagnosed OSA patients were included. Each patient was matched with non-OSA controls from the general population by propensity score matching (1:1) based on age, gender, hypertension, hyperlipidemia, ankylosing spondylitis, and Charlson comorbidity index, 8,037 OSA and an equal number of non-OSA subjects were used to compared in this study. The incidence of FD was assessed at the end of 2013 and cumulative incidences, hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated. Results: The adjusted HR (aHR)of FD for the OSA group was 2.082-fold (95% CI = 1.149–3.773, p=0.0155) higher than non-OSA group. The stratified analyses revealed aHR of FD for the hyperlipidemia group was 2.264-fold (95% CI = 1.061–4.832, p=0.035). Subgroup analysis showed the subjected of female OSA had more risk to develop FD (aHR:2.345, 95% CI = 1.026–5.357, p=0.043). Conclusion: A higher risk of developing FD was found among the newly diagnosed OSA cohort during the longer than 10-year follow-up period

Community Dwelling Older Adults

ABSTRACTBackground: Antipsychotics are associated with adverse events and mortality among older adults with dementia. The objective of this study was to evaluate the risk of death associated with antipsychotic use among community-dwelling older adults with a range of comorbidities.Methods: This was a population-based cohort study of all 2,224 residents of Leppävirta, Finland, aged ≥65 years on 1 January 2000. Records of all reimbursed drug purchases were extracted from the Finnish National Prescription Register and diagnostic data were obtained from the Special Reimbursement Register. All-cause mortality was evaluated over a nine-year follow-up period. Time-dependent Cox proportional hazard models were used to compute unadjusted and adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of mortality of antipsychotic use compared to non-use.Results: In total, 332 residents used antipsychotics between 2000 and 2008. The unadjusted HR for risk of death associated with antipsychotic use was 2.71 (95% CI = 2.3–3.2). After adjusting for baseline age, sex, antidepressant use, and diagnostic confounders, the HR was 2.07 (95% CI = 1.73–2.47). The adjusted HR was the highest among antipsychotic users with baseline respiratory disease (HR = 2.21, 95% CI = 1.30–3.76).Conclusions: The increased risk of death associated with antipsychotic use was similar across diagnostic categories, the highest being among those with baseline respiratory disease. However, the results should be interpreted with caution, as the overall sample size of antipsychotic users was small. As in other observational studies, residual confounding may account for the higher mortality observed among antipsychotic users. Further research is needed to confirm these findings.

The Relationship

AbstractPatients with hepatocellular carcinoma (HCC) might be more vulnerable to develop stroke than other cancer patients because of HCC-associated coagulation dysfunction. However, limited studies have investigated the relationship between HCC and stroke. This nationwide population-based cohort study enrolled all patients with HCC diagnosed between 2011 and 2015 from the Taiwan Cancer Registry and Taiwan National Health Insurance Research Database; an age- and sex-matched cohort without cancer was included. The primary outcome was the 1-year risk for first-ever stroke after the index date. The Fine and Gray competing risk regression model was used to estimate the 1-year stroke risk with adjusted hazard ratios (aHRs). After propensity score matching, each cohort has 18,506 patients with similar baseline characteristics. Compared with the cancer-free cohort, the aHRs in the HCC cohort for overall, ischemic, and hemorrhagic strokes were 1.59 [95% confidence interval (CI), 1.35–1.88], 1.38 [95% CI, 1.15–1.65], and 2.62 [95% CI, 1.79–3.84], respectively. On subgroup analysis, HCC patients without cirrhosis, those with stage 3 or 4 cancer had a higher stroke risk than cancer-free cohort. Therefore, stroke prevention should be considered in patients with HCC, especially in those without cirrhosis and with stage 3 or 4 cancer.
