Association between holiday and weekend admissions and mortality outcomes among patients with acute myocardial infarction receiving percutaneous coronary intervention in Taiwan.

There is a lack of studies that concurrently differentiate the effect of the holiday season from the weekend effect on mortality risk in patients with acute myocardial infarction (AMI). We evaluated the mortality risk among patients admitted with AMI who underwent percutaneous coronary intervention, using data from the Taiwan National Health Insurance Research Database. Adult AMI patients admitted during January and February between 2013 and 2020 were enrolled and classified into the holiday season (using the Chinese New Year holiday seasons as an indicator) (n = 1729), weekend (n = 4725), and weekday (n = 14,583) groups according to the first day of admission. A multivariable logistic regression model was used to assess the risk. With the weekday group or the weekend group as the reference, the holiday season group did not have increased risks of in-hospital mortality (adjusted odds ratio [aOR] 1.15; 95% confidence intervals [CI] 0.93-1.42 or aOR 1.23; 95% CI 0.96-1.56) and 7-day mortality (aOR 1.20; 95% CI 0.90-1.58 or aOR 1.24; 95% CI 0.90-1.70). Stratified and subgroup analyses showed similar trends. We conclude that holiday season-initiated admissions were not associated with higher mortality risks in AMI admission cases than weekday or weekend admissions.

MACE and Hyperthyroidism Treated With Medication, Radioactive Iodine, or Thyroidectomy.

Importance: Excessive thyroid hormones from hyperthyroidism increase cardiovascular risks. Among 3 available treatments for hyperthyroidism, comparisons of long-term outcomes associated with antithyroid drugs (ATDs), radioactive iodine (RAI), and surgery to treat newly diagnosed hyperthyroidism are lacking. Objective: To compare risks of major adverse cardiovascular events (MACE) and all-cause mortality among patients with hyperthyroidism treated with ATDs, RAI, or surgery. Design, Setting, and Participants: This nationwide cohort study used the Taiwan National Health Insurance Research Database. Patients aged 20 years or older with newly diagnosed hyperthyroidism between 2011 and 2020 were enrolled. Treatment groups were determined within 18 months from diagnosis, with follow-up until the development of MACE, death, or the end date of the database, whichever came first. Data were analyzed from October 2022 through December 2023. Exposures: The ATD group received ATDs only. RAI and surgery groups could receive ATDs before treatment. Anyone who underwent thyroid surgery without RAI was classified into the surgery group and vice versa. Main Outcomes and Measures: The primary outcomes included MACE (a composite outcome of acute myocardial infarction, stroke, heart failure, and cardiovascular mortality) and all-cause mortality. Results: Among 114 062 patients with newly diagnosed hyperthyroidism (mean [SD] age, 44.1 [13.6] years; 83 505 female [73.2%]), 107 052 patients (93.9%) received ATDs alone, 1238 patients (1.1%) received RAI, and 5772 patients (5.1%) underwent surgery during a mean (SD) follow-up of 4.4 (2.5) years. Patients undergoing surgery had a significantly lower risk of MACE (hazard ratio [HR] = 0.76; 95% CI, 0.59-0.98; P = .04), all-cause mortality (HR = 0.53; 95% CI, 0.41-0.68; P < .001), heart failure (HR = 0.33; 95% CI, 0.18-0.59; P < .001), and cardiovascular mortality (HR = 0.45; 95% CI, 0.26-0.79; P = .005) compared with patients receiving ATDs. Compared with ATDs, RAI was associated with lower MACE risk (HR = 0.45; 95% CI, 0.22-0.93; P = .03). Risks for acute myocardial infarction and stroke did not significantly differ between treatment groups. Conclusions and Relevance: In this study, surgery was associated with lower long-term risks of MACE and all-cause mortality, while RAI was associated with a lower MACE risk compared with ATDs.

Helicobacter pylori eradication with high-dose proton pump inhibitor-amoxicillin dual therapy: A systematic review and meta-analysis.

BACKGROUND: Resistance of Helicobacter pylori to many antibiotics, which lowers the efficacy of eradication therapy, is increasingly prevalent. High-dose proton pump inhibitor (PPI)-amoxicillin dual therapy (HDDT) has been used for H. pylori eradication for years, and resistance to amoxicillin is relatively rare. Although many studies have compared the eradication rate of HDDT with that of guideline therapies, the reported efficacy of HDDT varies greatly and is inconsistent. AIMS: This study investigated the eradication rate and adverse effects of HDDT compared with the guidelines at the time of the study. METHODS: Several open public databases, including Cochrane, EMBASE, PubMed, and MEDLINE, were searched. The results of the current literature on the eradication and adverse event rates of HDDT compared with the latest recommended first-line therapies were analysed. Notably, 14 out of the 16 included studies were conducted in Asian regions. RESULTS: The eradication rate of HDDT was lower but not significantly different from those of control therapies (odds ratio [OR] = 0.92, 95% confidence interval [CI] = 0.67-1.26) in the intent-to-treat (ITT) analysis. A similar trend was observed in the per-protocol (PP) analysis (OR = 0.88, 95% CI = 0.47-1.63). Notably, the adverse effect risk in HDDT was significantly lower than in other therapies (I2 = 67.75%, OR = 0.42, 95% CI = 0.33-0.54, P = 0.00004). When the eradication rate of the control group was lower than 81%, HDDT was significantly better than control therapies (OR = 2.44, 95% CI = 1.23-4.84). CONCLUSION: HDDT used four times a day for 14 days showed better efficacy and safety than the guideline treatments for H. pylori infection in areas with high antimicrobial resistance.

Denosumab and the Risk of Diabetes in Patients Treated for Osteoporosis.

Importance: Denosumab, a humanized monoclonal antibody against receptor activator of nuclear factor κB ligand (RANKL), is a widely used antiresorptive medication for osteoporosis treatment. Recent preclinical studies indicate that inhibition of RANKL signaling improves insulin sensitivity, glucose tolerance, and ß-cell proliferation, suggesting that denosumab may improve glucose homeostasis; however, whether denosumab reduces the risk of incident diabetes remains unclear. Objective: To evaluate whether denosumab use is associated with a lower risk of developing diabetes in patients with osteoporosis. Design, Setting, and Participants: This nationwide, propensity score-matched cohort study used administrative data from Taiwan's National Health Insurance Research Database. Adult patients who received denosumab for osteoporosis therapy in Taiwan between 2012 and 2019 were included. To eliminate the inherent bias from confounding by indication, the patients were categorized into a treatment group (34 255 patients who initiated denosumab treatment and adhered to it) and a comparison group (34 255 patients who initiated denosumab treatment but discontinued it after the initial dose) according to the administration status of the second dose of denosumab. Propensity score matching was performed to balance patient characteristics and to control for confounders. Exposure: Treatment with denosumab. Main Outcomes and Measures: The primary outcome was incident diabetes requiring treatment with antidiabetic drugs. A Cox proportional hazards model was used to estimate the hazard ratio (HR) for incident diabetes. Data were analyzed from January 1 to November 30, 2023. Results: After propensity score matching, 68 510 patients were included (mean [SD] age, 77.7 [9.8] years; 57 762 [84.3%] female). During a mean (SD) follow-up of 1.9 (1.6) years, 2016 patients developed diabetes in the treatment group and 3220 developed diabetes in the comparison group (incidence rate, 35.9 vs 43.6 per 1000 person-years). Compared with the comparison group, denosumab treatment was associated with a lower risk of incident diabetes (HR, 0.84; 95% CI, 0.78-0.90). Several sensitivity analyses also demonstrated similar results of lower diabetes risk associated with denosumab treatment. Conclusions and relevance: The results from this cohort study indicating that denosumab treatment was associated with lower risk of incident diabetes may help physicians choose an appropriate antiosteoporosis medication for patients with osteoporosis while also considering the risk of diabetes.

Off-hours Surgery and Mortality in Patients With Type A Aortic Dissection Repair: A Systematic Review and Meta-Analysis.

BACKGROUND AND OBJECTIVES: The impact of off-hours admission (such as weekends, nighttime, and non-working hours) vs. regular hours (weekdays and daytime working hours) on the mortality risk of patients undergoing surgery for type A aortic dissection (TAAD) repair is still uncertain. To address this uncertainty, we undertook a comprehensive systematic review and meta-analysis. We aimed to assess the potential link between off-hours admission and the risk of mortality in patients undergoing TAAD repair surgery. METHODS: We conducted a thorough search of the PubMed, Embase, and Cochrane Library databases, covering the period from their inception to May 20, 2023. Our inclusion criteria encompassed all studies that examined the potential relationship between off-hour admission and mortality in individuals who had undergone surgery for TAAD repair. The odds ratios (ORs) were extracted and combined utilizing a random effects model for our synthesis. RESULTS: Nine studies with 16,501 patients undergoing TAAD repair surgery were included in the meta-analysis. Overall, patients who underwent surgery during the weekend had higher in-hospital mortality (pooled OR, 1.41; 95% confidence interval [CI], 1.14-1.75; p=0.002) than those treated on weekdays. However, the mortality risks among patients who underwent TAAD surgery during nighttime and non-working hours were not significantly elevated compared to daytime and working hours admission. CONCLUSIONS: Weekend surgery for TAAD was associated with a higher in-hospital mortality risk than weekday surgery. However, further studies are warranted to identify and develop strategies to improve the quality of round-the-clock care for patients with TAAD.

Risk of Bleeding Following Non-Vitamin K Antagonist Oral Anticoagulant Use in Patients With Acute Ischemic Stroke Treated With Alteplase.

Importance: Current guidelines advise against intravenous alteplase therapy for treatment of acute ischemic stroke in patients previously treated with non-vitamin K antagonist oral anticoagulants (NOACs). Objective: To evaluate the risk of bleeding and mortality after alteplase treatment for acute ischemic stroke among patients treated with NOACs compared to those not treated with NOACs. Design, Setting, and Participants: This nationwide, population-based cohort study was conducted in Taiwan using data from Taiwan's National Health Insurance Research Database from January 2011 through November 2020 and included 7483 patients treated with alteplase for acute ischemic stroke. A meta-analysis incorporating the results of the study with those of previous studies was performed, and the review protocol was prospectively registered with PROSPERO. Exposures: NOAC treatment within 2 days prior to stroke, compared to either no anticoagulant treatment or warfarin treatment. Main Outcomes and Measures: The primary outcome was intracranial hemorrhage after intravenous alteplase during the index hospitalization (the hospitalization subsequent to alteplase administration). Secondary outcomes were major bleeding events and mortality during the index hospitalization. Propensity score matching was used to control potential confounders. Logistic regression was used to estimate the odds ratio (OR) of outcome events. Meta-analysis was performed using a random-effects model. Results: Of the 7483 included patients (mean [SD] age, 67.4 [12.7] years; 2908 [38.9%] female individuals and 4575 [61.1%] male individuals), 91 (1.2%), 182 (2.4%), and 7210 (96.4%) received NOACs, warfarin, and no anticoagulants prior to their stroke, respectively. Compared to patients who were not treated with anticoagulants, those treated with NOACs did not have significantly higher risks of intracranial hemorrhage (risk difference [RD], 2.47% [95% CI, -4.23% to 9.17%]; OR, 1.37 [95% CI, 0.62-3.03]), major bleeding (RD, 4.95% [95% CI, -2.56% to 12.45%]; OR, 1.69 [95% CI, 0.83-3.45]), or in-hospital mortality (RD, -4.95% [95% CI, -10.11% to 0.22%]; OR, 0.45 [95% CI, 0.15-1.29]) in the propensity score-matched analyses. Furthermore, the risks of bleeding and mortality were not significantly different between patients treated with NOACs and those treated with warfarin. Similar results were obtained in the meta-analysis. Conclusions and Relevance: In this cohort study with meta-analysis, compared to no treatment with anticoagulants, treatment with NOACs prior to stroke was not associated with a higher risk of intracranial hemorrhage, major bleeding, or mortality in patients receiving intravenous alteplase for acute ischemic stroke.

Sodium-glucose co-transporter-2 inhibitors and the risk of venous thromboembolism: A nationwide population-based study and meta-analysis.

AIMS: Sodium-glucose cotransporter-2 inhibitors (SGLT-2i) have off-target effects on haemoconcentration and anti-inflammation. The impact of SGLT-2i on the risk of venous thromboembolism (VTE) in patients with diabetes mellitus (DM) remains unclear. This study aimed to evaluate the risk of newly diagnosed VTE in patients with DM using SGLT-2i in comparison to dipeptidyl peptidase-4 inhibitors (DPP-4i) or glucagon-like peptide-1 receptor agonists (GLP-1RA). MATERIALS AND METHODS: In this nationwide retrospective cohort study, we used data from Taiwan's National Health Insurance Research Database. Patients with diabetes aged 20 years or older who received SGLT-2i, DPP-4i, or GLP-1RA between 1 May 2016, and 31 December 2020, were included. The risks of VTE in SGLT-2i users were compared with those of DPP-4i and GLP-1RA users. A Cox regression model with stabilised inverse probability of treatment weighting was used to calculate hazard ratio (HR) for VTE risk. Additionally, a meta-analysis of relevant articles published before 23 May 2023, was conducted. RESULTS: Data from 136,530 SGLT-2i, 598,280 DPP-4i, and 5760 GLP-1RA users were analysed. SGLT-2i use was associated with a lower risk of VTE than DPP-4i (HR, 0.70; 95% CI, 0.59-0.84; p < 0·001), but not with GLP-1RA (HR, 1.39; 95% CI, 0.32-5.94; p = 0.66). Our meta-analysis further supported these findings (SGLT-2i vs. DPP-4i: HR, 0.71; 95% CI, 0.62-0.82; p < 0·001; SGLT-2i vs. GLP-1RA: HR, 0.91; 95% CI, 0.73-1.15; p = 0.43), suggesting the robustness of our retrospective analysis. CONCLUSIONS: In patients with DM, SGLT-2i was associated with a lower risk of VTE compared to DPP-4i, but not GLP-1RA.

Risk of Incident Venous Thromboembolism Among Patients With Bullous Pemphigoid or Pemphigus Vulgaris: A Nationwide Cohort Study With Meta-Analysis.

Background Bullous pemphigoid (BP) and pemphigus vulgaris (PV) share similar pathophysiology with venous thromboembolism (VTE) involving platelet activation, immune dysregulation, and systemic inflammation. Nevertheless, their associations have not been well established. Methods and Results To examine the risk of incident VTE among patients with BP or PV, we performed a nationwide cohort study using Taiwan's National Health Insurance Research Database and enrolled 12 162 adults with BP or PV and 12 162 controls. A Cox regression model considering stabilized inverse probability weighting was used to calculate the hazard ratios (HRs) for incident VTE associated with BP or PV. To consolidate the findings, a meta-analysis that incorporated results from the present cohort study with previous literature was also conducted. Compared with controls, patients with BP or PV had an increased risk for incident VTE (HR, 1.87 [95% CI, 1.55-2.26]; P<0.001). The incidence of VTE was 6.47 and 2.20 per 1000 person-years in the BP and PV cohorts, respectively. The risk for incident VTE significantly increased among patients with BP (HR, 1.85 [95% CI, 1.52-2.24]; P<0.001) and PV (HR, 1.99 [95% CI, 1.02-3.91]; P=0.04). In the meta-analysis of 8 studies including ours, BP and PV were associated with an increased risk for incident VTE (pooled relative risk, 2.17 [95% CI, 1.82-2.62]; P<0.001). Conclusions BP and PV are associated with an increased risk for VTE. Preventive approaches and cardiovascular evaluation should be considered particularly for patients with BP or PV with concomitant risk factors such as hospitalization or immobilization.

Risk of Venous Thromboembolism Among Adults With Atopic Dermatitis.

Importance: The associations of atopic dermatitis (AD) with multiple cardiovascular comorbidities have been investigated because of its pathomechanisms regarding chronic systemic inflammation and potential vascular effects. Nevertheless, the association between AD and incident venous thromboembolism (VTE) in adulthood is largely unknown. This study aimed to investigate the association of AD with incident VTE. Objective: To examine the risk of incident VTE among patients with AD. Design, Setting, and Participants: This population-based nationwide cohort study included adults 20 years or older (adults with AD newly diagnosed between 2003 and 2017 and matched controls) from the National Health Insurance Research Database. Patients with AD were subgrouped according to the severity of the disease. A Cox regression model was used to estimate hazard ratios (HRs) for VTE. Stratified analyses according to age and sex, and a sensitivity analysis excluding systemic steroid users were performed. Main Outcomes and Measures: Hazard ratios (HRs) for incident VTE associated with AD. Results: This analysis included a total of 284 858 participants, with 142 429 participants each in the AD (mean [SD] age, 44.9 [18.3] years; 78 213 women) and non-AD cohorts (mean [SD] age, 44.1 [18.1] years; 79 636 women). During the follow-up, 1066 patients (0.7%) in the AD cohort and 829 patients (0.6%) in the non-AD cohort developed VTE, with incidence rates of 1.05 and 0.82 per 1000 person-years, respectively. Adults with AD had a significantly increased risk of incident VTE (HR, 1.28; 95% CI, 1.17-1.40) compared with adults without AD. Individual outcome analyses suggested that AD was associated with higher risks of deep vein thrombosis (HR, 1.26; 95% CI, 1.14-1.40) and pulmonary embolism (HR, 1.30; 95% CI, 1.08-1.57). Conclusions and Relevance: The results of this cohort study suggest that AD in adulthood is associated with an increased risk of VTE; however, the absolute risk difference of VTE between adults with and without AD appears small. Nevertheless, cardiovascular examination and imperative management may be considered for adults with AD who present with symptoms suggestive of VTE. Future research is warranted to elucidate the pathophysiology underlying the association between AD and VTE.

Association between bisphosphonate use and stroke risk: a meta-analysis.

Previous studies have suggested that bisphosphonates may reduce stroke risk. This meta-analysis, which included 21 studies with 741,274 participants, revealed that bisphosphonates might be associated with lower stroke risk. However, evidence derived from randomized controlled trials identified no statistically significant association. Future high-quality studies are still required to determine causality. PURPOSE: Whether bisphosphonates may reduce the risk of stroke remains inconclusive. We conducted a systematic review and meta-analysis to evaluate the association between bisphosphonate use and the risk of stroke based on up-to-date evidence. METHODS: We searched for studies evaluating the effects of bisphosphonate on the risk of stroke from inception until January 3, 2022, on PubMed, Embase, Scopus, and Cochrane libraries and updated our search until August 22, 2022, using PubMed to identify any new potential published studies. Two or more reviewers independently screened articles, extracted data, and assessed the study quality. We retrieved the data to synthesize the pooled relative risk (RR) of stroke associated with bisphosphonate use compared with controls; random-effects models were used for meta-analysis. RESULTS: A total of 21 studies (7 randomized controlled trials [RCTs] and 14 observational studies) involving 741,274 participants were included in our meta-analysis. Overall, bisphosphonate use was associated with a lower risk of stroke, but the result was only borderline significant (pooled RR = 0.87, 95% confidence interval [CI]: 0.76-0.99, p = 0.048), and high between-study heterogeneity was found (I2 = 83.7%). Subgroup analyses showed that the evidence derived from RCTs suggested no significant association between bisphosphonate use and stroke risk (pooled RR = 0.93, 95% CI: 0.76-1.13, p = 0.462; I2 = 13.4%). CONCLUSION: Our results suggest that bisphosphonate use is associated with a lower risk of stroke. However, the current evidence does not lead to a definite conclusion due to the borderline statistical significance and high between-study heterogeneity. Future studies, especially RCTs, are necessary to assess causality.

Risk of serious hypoglycaemia in patients with atrial fibrillation and diabetes concurrently taking antidiabetic drugs and oral anticoagulants: a nationwide cohort study.

AIMS: Evidence regarding the risks of serious hypoglycaemia for patients with atrial fibrillation (AF) and diabetes mellitus (DM) taking antidiabetic medications with concurrent non-vitamin K antagonist oral anticoagulants (NOACs) vs. warfarin is limited. This study aimed to investigate this knowledge gap. METHODS AND RESULTS: This retrospective cohort study used nationwide data from Taiwan's National Health Insurance Research Database and included a total of 56 774 adult patients treated with antidiabetic medications and oral anticoagulants between 1 January 2012 and 31 December 2020. The incidence rate ratios (IRRs) of serious hypoglycaemia were estimated for patients taking antidiabetic drugs with NOACs vs. warfarin. Poisson regression models with generalized estimating equations accounting for intra-individual correlation across follow-up periods were used. Stabilized inverse probability of treatment weighting was used to create treatment groups with balanced characteristics for comparisons. Compared to concurrent use of antidiabetic drugs with warfarin, those with NOACs showed a significantly lower risk of serious hypoglycaemia (IRR = 0.73, 95% CI: 0.63-0.85, P < 0.001). In the analyses of each NOAC, patients taking dabigatran (IRR = 0.76, 95% CI: 0.63-0.91, P = 0.002), rivaroxaban (IRR = 0.72, 95% CI: 0.61-0.86, P < 0.001), and apixaban (IRR = 0.71, 95% CI: 0.57-0.89, P = 0.003) showed a significantly lower risk of serious hypoglycaemia than those taking warfarin. CONCLUSION: In patients with AF and DM taking antidiabetic drugs, concurrent use of NOACs was associated with a lower risk of serious hypoglycaemia than concurrent use of warfarin.

The efficacy and safety of cupping as complementary and alternative therapy for metabolic syndrome: A systematic review and meta-analysis.

INTRODUCTION: This systematic review and meta-analysis aimed to assess the efficacy and safety of cupping therapy in patients with metabolic syndrome (MetS). METHODS: This systematic review focused on patients with MetS and included randomized controlled trials (RCTs) that compared the effects of cupping therapy with control groups. A total of 12 electronic databases were searched from inception until February 03, 2023. The main outcome after the meta-analysis was waist circumference; the others included anthropometric variables, blood pressure, lipid profile, fasting blood glucose level, and high-sensitivity C-reactive protein level. The incidence of adverse events and the follow-up courses were also evaluated. Risk of bias (ROB) was evaluated using ROB 2.0 from the Cochrane Handbook. RESULTS: This systematic review included five studies involving 489 patients. Some risks of bias were also identified. The meta-analysis revealed a statistically significance in waist circumference (MD = -6.07, 95% CI: -8.44 to -3.71, P < .001, I2 = 61%, τ2 = 3.4), body weight (MD = -2.46, 95% CI: -4.25 to -0.68, P = .007, I2 = 0%, τ2 = 0) and body mass index (MD = -1.26, 95% CI: -2.11 to -0.40, P = .004, I2 = 0%, τ2 = 0) between the cupping therapy and control groups. However, there were no significant results in total fat percentage and blood pressure values. Regarding biochemical markers, cupping significantly lowered the concentration of low-density lipoprotein cholesterol (MD = -3.98, 95% CI: -6.99 to -0.96, P = .010, I2 = 0%, τ2 = 0) but had no significant effect on total cholesterol, triglyceride, high-density lipoprotein cholesterol, fasting blood glucose, and high-sensitivity C-reactive protein. 3 RCTs reported no adverse events. CONCLUSIONS: Despite some ROB and low to substantial heterogeneity of the included studies, cupping therapy can be considered a safe and effective complementary intervention for reducing waist circumference, body weight, body mass index, and low-density lipoprotein cholesterol in patients with MetS. In the future, well-designed, high-quality, rigorous methodology, and long-term RCTs in this population are required to assess the efficacy and safety of cupping therapy.

Clinical practice guidelines for the prevention and treatment of osteoporosis in Taiwan: 2022 update.

Osteoporosis greatly increases the risk of fractures. Osteoporotic fractures negatively impact quality of life, increase the burden of care, and increase mortality. Taiwan is an area with a high prevalence of osteoporosis. This updated summary of guidelines has been developed by experts of the Taiwan Osteoporosis Association with the intention of reducing the risks of osteoporotic fractures and improving the quality of care for patients with osteoporosis. The updated guidelines compile the latest evidence to provide clinicians and other healthcare professionals with practical recommendations for the prevention, diagnosis, and management of osteoporosis under clinical settings in Taiwan.

Risk of heart failure in elderly patients with atrial fibrillation and diabetes taking different oral anticoagulants: a nationwide cohort study.

BACKGROUND: Heart failure (HF) is a critical complication in elderly patients with atrial fibrillation (AF) and diabetes mellitus (DM). Recent preclinical studies suggested that non-vitamin K antagonist oral anticoagulants (NOACs) can potentially suppress the progression of cardiac fibrosis and ischemic cardiomyopathy. Whether different oral anticoagulants influence the risk of HF in older adults with AF and DM is unknown. This study aimed to evaluate the risk of HF in elderly patients with AF and DM who were administered NOACs or warfarin. METHODS: A nationwide retrospective cohort study was conducted based on claims data from the entire Taiwanese population. Target trial emulation design was applied to strengthen causal inference using observational data. Patients aged ≥ 65 years with AF and DM on NOAC or warfarin treatment between 2012 and 2019 were included and followed up until 2020. The primary outcome was newly diagnosed HF. Propensity score-based fine stratification weightings were used to balance patient characteristics between NOAC and warfarin groups. Hazard ratios (HRs) were estimated using Cox proportional hazard models. RESULTS: The study included a total of 24,835 individuals (19,710 NOAC and 5,125 warfarin users). Patients taking NOACs had a significantly lower risk of HF than those taking warfarin (HR = 0.80, 95% CI 0.74-0.86, p < 0.001). Subgroup analyses for individual NOACs suggested that dabigatran (HR = 0.86, 95% CI 0.80-0.93, p < 0.001), rivaroxaban (HR = 0.80, 95% CI 0.74-0.86, p < 0.001), apixaban (HR = 0.78, 95% CI 0.68-0.90, p < 0.001), and edoxaban (HR = 0.72, 95% CI 0.60-0.86, p < 0.001) were associated with lower risks of HF than warfarin. The findings were consistent regardless of age and sex subgroups and were more prominent in those with high medication possession ratios. Several sensitivity analyses further supported the robustness of our findings. CONCLUSIONS: This nationwide cohort study demonstrated that elderly patients with AF and DM taking NOACs had a lower risk of incident HF than those taking warfarin. Our findings suggested that NOACs may be the preferred oral anticoagulant treatment when considering the prevention of heart failure in this vulnerable population. Future research is warranted to elucidate causation and investigate the underlying mechanisms.

Association of bisphosphonates with diabetes risk and glycemic control: a meta-analysis.

Previous evidence suggests that bisphosphonates may improve glycemic control. The present meta-analysis, comprising seven studies with 1,233,844 participants, demonstrated that bisphosphonate use was significantly associated with a lower risk of diabetes. However, in the randomized controlled trial subgroup, a non-significant association was found. Further studies are needed to determine causality. PURPOSE: This study aimed to evaluate the impact of bisphosphonates on glycemic control and the risk of incident diabetes. METHODS: MEDLINE, Embase, and Cochrane Library were searched from inception to February 15, 2022. Experimental or observational studies that compared fasting blood glucose (FBG) and glycated hemoglobin (HbA1c) levels and the diabetes risk with and without bisphosphonates were included. Studies without relevant outcomes, only providing crude estimates, or the absence of a control group were excluded. Two reviewers independently screened the articles, extracted data, and appraised studies. The pooled relative risk (RR) and weighted mean difference (WMD) were calculated using random effects models. RESULTS: Seven studies (n = 1,233,844) on diabetes risk were included, including two post hoc analyses of randomized controlled trials (RCTs) and five observational studies. Compared with controls, bisphosphonates (BPs) were associated with a significant decrease in the risk of diabetes (RR = 0.77; 95% CI, 0.65 to 0.90; P = 0.002). However, in the subgroup of post hoc analyses of RCTs, the association was non-significant (RR = 0.93; 95% CI, 0.74 to 1.18; P = 0.576). Moreover, three studies (n = 4906) on FBG and one (n = 60) on HbA1c were included. We observed non-significant association between BPs and changes in FBG (WMD = - 0.61 mg/dL; 95% CI, - 2.72 to 1.49; P = 0.567) and HbA1c (WMD = - 0.11%; 95% CI, - 0.23 to 0.01; P = 0.083). CONCLUSION: Patients taking BPs may have a lower risk of incident diabetes than those without BPs. However, due to the high between-study heterogeneity and inconsistent findings between post hoc analyses of RCTs and observational studies, further rigorous RCTs are required to determine whether the findings are causal.

Risk of Subsequent Dementia or Alzheimer Disease Among Patients With Age-Related Macular Degeneration: A Systematic Review and Meta-analysis.

PURPOSE: Alzheimer disease (AD), a common form of dementia, shares several clinical and pathologic features with age-related macular degeneration (AMD). Epidemiologic reports on the association of AMD with subsequent dementia or AD are inconsistent. DESIGN: Systematic review and meta-analysis. METHODS: The Meta-analysis of Observational Studies in Epidemiology reporting guidelines were applied. The Newcastle-Ottawa Scale was used to evaluate the risk of bias in the included cohort studies that examined the association of AMD with subsequent dementia or AD. We estimated the pooled hazard ratios (HRs) of dementia or AD using random effects model meta-analysis and subgroup analysis on different follow-up periods, AMD subtype, gender, age, study design, and methods to ascertain dementia or AD. RESULTS: A total of 8 223 581 participants were included in 8 studies published during 2000-2021. The meta-analysis showed that AMD was significantly associated with subsequent dementia (pooled HR 1.22, 95% CI 1.01-1.47) or AD (pooled HR 1.21, 95% CI 1.03-1.43). Our secondary analysis revealed that the association was more noticeable in dry AMD than wet AMD. CONCLUSIONS: Patients with AMD have higher risks of developing dementia or AD, and therefore identifying related comorbidities and retinal biomarkers is much warranted for older adults with AMD in ophthalmologic practice.

Long-Term Risks of Stroke in Patients With Type A Aortic Dissection: A Nationwide Cohort Study.

Background Patients with type A aortic dissection (TAAD) have a high short-term risk of stroke. However, whether patients with TAAD have an increased long-term risk of stroke is still undetermined, and our study aims to address this knowledge gap. Methods and Results A nationwide retrospective cohort study was conducted using Taiwan's National Health Insurance Research Database. We included patients with TAAD as well as age- and sex-matched aortic disease-free individuals between 2003 and 2016. Inverse probability of treatment weighting was performed to balance patient characteristics between the groups. The primary outcome was the development of stroke, regardless of subtype; the secondary outcomes were the risk of developing either ischemic or hemorrhagic stroke. The hazard ratios (HRs) of stroke were estimated using the Cox proportional hazards model. After inverse probability of treatment weighting, 3556 and 7023 patients were categorized into the TAAD and aortic disease-free cohorts, respectively. The mean follow-up period was 5.71 years. The HRs for overall, ischemic, and hemorrhagic strokes in the TAAD cohort were 3.01 (95% CI, 2.40-3.78), 3.18 (95% CI, 2.47-4.10), and 2.32 (95% CI, 1.58-3.41), respectively, compared with the aortic disease-free cohort. Consistent trends of higher stroke risk in patients with TAAD were revealed in the analyses stratified by age; sex; antiplatelet use; and history of hypertension, diabetes, or dyslipidemia. Conclusions Our study findings revealed that patients with TAAD had an increased long-term risk of both ischemic and hemorrhagic strokes. Further studies are warranted to establish optimal strategies for stroke prevention in these patients.

Association of Risk of Incident Venous Thromboembolism With Atopic Dermatitis and Treatment With Janus Kinase Inhibitors: A Systematic Review and Meta-analysis.

Importance: The risk of venous thromboembolism (VTE) among patients with atopic dermatitis (AD), especially when receiving treatment with Janus kinase (JAK) inhibitors, is unclear. Objective: To determine the association of AD with incident VTE and evaluate the risk of incident VTE among patients with AD who were receiving treatment with JAK inhibitors. Data Sources: The MEDLINE, Embase, Cochrane Library, and Web of Science databases were searched with no restrictions on language nor geographic locations from their respective inception to February 5, 2022. Study Selection: Cohort studies examining the association of AD with incident VTE and randomized clinical trials (RCTs) reporting VTE events in participants with AD receiving JAK inhibitors were included. Around 0.7% of initially identified articles met the selection criteria. Data Extraction and Synthesis: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed. The risk of bias of included cohort studies and RCTs was assessed by the Newcastle-Ottawa Scale and the Cochrane Risk of Bias Tool 2, respectively. A random-effects model meta-analysis was conducted to calculate the pooled hazard ratio (HR) and risk difference for incident VTE. Main Outcomes and Measures: The HRs for incident VTE associated with AD and risk difference for incident VTE between participants with AD who were receiving treatment with JAK inhibitors and controls receiving placebo or dupilumab. Results: Two cohort studies and 15 RCTs with a total of 466 993 participants were included. The meta-analysis found no significant association of AD with incident VTE (HR, 0.95; 95% CI 0.62-1.45; incidence rate of VTE, 0.23 events/100 patient-years). Overall, 3 of 5722 patients with AD (0.05%) who were receiving treatment with JAK inhibitors experienced VTE compared with 1 of 3065 patients with AD (0.03%) receiving placebo or dupilumab (Mantel-Haenszel risk difference, 0; 95% CI, 0-0). The incidence rate of VTE was 0.15 and 0.12 events per 100 patient-years in participants with AD receiving JAK inhibitors and placebo, respectively. The findings were similar in 4 unique JAK inhibitors (abrocitinib, baricitinib, upadacitinib, and SHR0302). Conclusions and Relevance: The results of this systematic review and meta-analysis suggest that the currently available evidence does not detect an increased risk of VTE associated with AD or treatment with JAK inhibitors. These findings may provide a reference for clinicians in prescribing JAK inhibitors for patients with AD.
