This study assessed the effects of dipeptidyl peptidase-4 inhibitors (DPP4is) vs. sulfonylureas (SUs) on composite renal, cardiovascular, and hospitalized hypoglycemia outcomes in type 2 diabetes (T2D) patients with advanced chronic kidney disease (CKD) who were underrepresented in previous clinical studies. The National Health Insurance Research Database was utilized. Patients with T2D and advanced CKD (stages 3b-5) with stable use of DPP4is or SUs were identified during 2011-2015 and followed until death or December 31, 2016. The primary outcome was the composite renal outcome. Secondary outcomes included hospitalized heart failure (HHF), major adverse cardiovascular event (MACE), hospitalized hypoglycemia, and all-cause death. Subdistribution hazard models were employed to assess treatment effects on clinical outcomes. A total of 1,204 matched pairs of DPP4i and SU users were analyzed. Compared with SUs, DPP4is had no significant difference in the risks of the composite renal outcome, HHF, and three-point and four-point MACE (hazard ratios (95% confidence intervals): 1.10 (0.93-1.31), 1.11 (0.95-1.30), 0.97 (0.79-1.19), and 1.08 (0.94-1.24), respectively), but reduced risks of hospitalized hypoglycemia (0.53 (0.43-0.64)) and all-cause death (0.71 (0.53-0.96)). In conclusion, among patients with T2D and advanced CKD, the use of DPP4is vs. SUs was associated with comparable safety profiles on renal and cardiovascular outcomes, and reduced risks of hospitalized hypoglycemia and all-cause death. DPP4is may be preferred for patients with T2D and advanced CKD, and the regular monitoring on cardiac function remains crucial among this population who are at a higher risk of HHF.

Objectives Although the efficacy of traditional 3-drug regimens for the treatment of HIV is well established, tolerability and toxicity concerns remain. New 2-drug regimens such as Juluca (dolutegravir [DTG]/rilpivirine [RPV]) offer noninferior efficacy versus 3-drug regimens (SWORD-1 and SWORD-2 studies), while reducing cumulative drug exposure and potentially long-term toxicities and drug-drug interactions. Here, we assess the cost-effectiveness of DTG/RPV for the treatment of HIV-1 for virologically suppressed adults in Taiwan. Methods A hybrid decision tree and Markov cohort state transition model was used to evaluate the expected economic costs and clinical outcomes associated with DTG/RPV and comparators. Model health states were defined by viral load and CD4 cell count. Efficacy and safety data were informed from SWORD-1 and SWORD-2 studies and the literature. The risk of long-term toxicities (cardiovascular disease, bone fractures, and chronic kidney disease) were included. Current branded drug acquisition prices were included, and healthcare costs informed by a bespoke costing study using National Health Insurance Research Database data. Incremental cost-effectiveness ratios were calculated and compared with a willingness-to-pay threshold of 2 times Taiwan’s gross domestic product (NT$1 550 000). Results DTG/RPV was found to be a cost-saving regimen compared to 3 comparators (rilpivirine [RPV]/emtricitabine [FTC]/tenofovir disoproxil fumarate [TDF], dolutegravir [DTG]/abacavir [ABC]/lamivudine [3TC], and elvitegravir [EVG]/cobicistat [c]/emtricitabine [FTC]/tenofovir alafenamide [TAF]) and fell in the southwest quadrant of the cost-effectiveness plane where it is generating significant savings with a small decrement in lifetime quality-adjusted life-years (–0.005). It was, however, more expensive than efavirenz [EFV]/emtricitabine [FTC]/ tenofovir disoproxil fumarate [TDF]. Conclusions DTG/RPV is cost-saving compared to RPV/FTC/TDF, DTG/ABC/3TC, and EVG/c/FTC/TAF, and provides comparable efficacy with reduced cumulative drug exposure.

OBJECTIVE The current study aims to assess the effect of early scale-up of antiretroviral therapy (ART) at HIV diagnosis on the economic burden of cardiometabolic diseases (CMDs) in HIV-infected population. DESIGN Cohort study. METHODS The study cohort comprised 10 693 newly diagnosed HIV patients without CMDs before HIV diagnosis identified from a nationwide HIV cohort in Taiwan. The patients were stratified by ART use [medication possession ratio ≥0.8: (high) vs.

Aims There is a lack of studies that rigorously and systematically assess the economic burden of cardiovascular diseases (CVDs) related to the use of antiretroviral therapy (ART). We aimed to assess the association between adherence to ART and economic burden of CVDs in an HIV-infected population. Methods Taiwan's National Health Insurance Research Database 2000–2011 was utilized for analyzing 18,071 HIV-infected patients free of CVDs before HIV diagnosis. The level of adherence to ART was measured by the medication possession ratio (MPR). Generalized estimating equations analysis was applied to estimate the cost impact of a variety of CVDs. All costs were presented in 2018 US dollars. Results The incidence of CVDs ranged from 0.17/1000 person-years (cardiogenic shock) to 2.60/1000 person-years (ischemic heart diseases (IHDs)). The mean annual medical cost for a base-case patient without CVDs was US$3000. Having cerebrovascular diseases, myocardial infarction, heart failure, arrhythmia, and IHDs increased annual costs by 41%, 33%, 30%, 16%, and 14%, respectively. The cost impact of incident CVDs in years with high adherence to ART (MPR ≥ 0.8) was significantly lower than that in years with low adherence (MPR Conclusion The economic burden of incident CVDs in an HIV-infected population was compelling and varied by the extent of using ART. A reduced economic impact of CVDs was found in years when patients possessed a greater adherence to ART.

Little is known about the comparative vascular safety of basal insulins (intermediate-acting human insulin [IAHI] or long-acting insulin analogue [LAIA]) in type 2 diabetes (T2D). This study sought to examine the vascular and hypoglycemic effects associated with IAHI versus LAIA in real-world patients with T2D. We utilized Taiwan’s National Health Insurance Research Database to identify T2D patients who stably used IAHI (N = 11,521) or LAIA (N = 37,651) in the period 2004–2012. A rigorous three-step matching algorithm that considered the initiation date of basal insulin, previous exposure of antidiabetic treatments, comorbidities, diabetes severity and complications, and concomitant medications was applied to achieve the between-group comparability. Study outcomes, including cardiovascular diseases (CVDs), microvascular diseases (MVDs), and hypoglycemia, were assessed up to the end of 2013. Compared with LAIA, the use of IAHI was associated with greater risks of composite CVDs (adjusted hazard ratio [aHR]: 1.79; 95% confidence interval [CI] 1.20–2.67) and hospitalized hypoglycemia (aHR: 1.82; 95% CI 1.51–2.20), but a lower risk of composite MVDs (aHR: 0.88; 95% CI 0.84–0.91). Subgroup and sensitivity analyses showed a consistent trend of results with that in the primary analyses. In summary, although the use of IAHI versus LAIA among T2D patients in usual practice may be associated with a lower risk of MVDs, strategies should be optimized for minimizing the risks of hypoglycemia and CVDs in this population.

Aims/Introduction To estimate preference‐based measures of health‐related quality of life associated with sociodemographic and clinical characteristics in type 2 diabetes patients. Materials and Methods Individuals with EuroQol‐5 dimensions‐3 levels data were identified from Taiwan’s National Health Interview Survey in 2009 and 2013. Status of diabetes, comorbidities, complications and treatments were ascertained through data linkage to Taiwan’s National Health Insurance Research Database. Multivariable ordinary least squares, Tobit and median regression analyses were used to estimate the coefficients that represented independent impacts of patients’ characteristics on health‐related quality of life. Results The mean health utility score for 2,104 participants was 0.838. Being female, aging, divorced/widowed, never worked or underweight, or having a lower monthly household income, injectable glucose‐lowering therapy, comorbid connective tissue disease or depression were associated with lower health utilities. Having an amputation led to the largest reduction by 0.288 in health utilities, followed by debilitating stroke (0.266), heart failure (0.237), other coronary heart disease (0.185), kidney dialysis/transplant (0.148), coronary revascularizations (0.093), transient ischemic attack/stroke (0.078), diabetic neuropathy (0.062), polyneuropathy (0.055) and other neuropathy (0.043). Conclusions Major vascular complications, connective tissue disease and depression are associated with considerably worse health‐related quality of life. These health utility estimates can facilitate health economic evaluations to determine cost‐effective strategies for diabetes management., This study estimated the health‐related quality of life associated with sociodemographic and clinical characteristics in type 2 diabetes patients. Major vascular complications, connective tissue disease and depression are associated with considerably worse health‐related quality of life. These health utility estimates can facilitate health economic evaluations to determine cost‐effective strategies for diabetes management.

Background Evidence is limited on excess risks of cardiovascular diseases (CVDs) associated with ambient air pollution in diabetic populations. Survival analyses without considering the spatial structure and possible spatial correlations in health and environmental data may affect the precision of estimation of adverse environmental pollution effects. We assessed the association between air pollution and CVDs in type 2 diabetes through a Bayesian spatial survival approach. Methods Taiwan’s national-level health claims and air pollution databases were utilized. Fine individual-level latitude and longitude were used to determine pollution exposure. The exponential spatial correlation between air pollution and CVDs was analyzed in our Bayesian model compared to traditional Weibull and Cox models. Results There were 2072 diabetic patients included in analyses. PM2.5 and SO2 were significant CVD risk factors in our Bayesian model, but such associations were attenuated or underestimated in traditional models; adjusted hazard ratio (HR) and 95% credible interval (CrI) or confidence interval (CI) of CVDs for a 1 μg/m3 increase in the monthly PM2.5 concentration for our model, the Weibull and Cox models was 1.040 (1.004–1.073), 0.994 (0.984–1.004), and 0.994 (0.984–1.004), respectively. With a 1 ppb increase in the monthly SO2 concentration, adjusted HR (95% CrI or CI) was 1.886 (1.642–2.113), 1.092 (1.022–1.168), and 1.091 (1.021–1.166) for these models, respectively. Conclusions Against traditional non-spatial analyses, our Bayesian spatial survival model enhances the assessment precision for environmental research with spatial survival data to reveal significant adverse cardiovascular effects of air pollution among vulnerable diabetic patients.

Purpose: Evidence for optimizing the first-line chemotherapy for patients with metastatic triple-negative breast cancer (mTNBC) is lacking. This study assessed the utilization patterns of chemotherapy and associated survival outcomes in de novo mTNBC patients. Methods: Taiwan's cancer registry was utilized to extract study patients with newly-diagnosed breast cancer during 2011–2015 and confirmed metastatic triple-negative status.The patients’ medical records (e.g., diseases, treatments) and death status were obtained from the National Health Insurance Research Database. Utilization of first-line chemotherapy regimens was analyzed and associated survival outcomes were assessed using Cox models. Results: 93.60% of the mTNBC patients (n = 297) received chemotherapy, where combination regimens (75.54%) were more common than single-agent regimens (24.46%) in the first-line setting. A non-statistically lower all-cause death associated with combination versus single-agent chemotherapy (hazard ratio: 0.830 [0.589, 1.168]) was observed. Age was identified as a significant effect-modifier in treatment-associated survival outcomes (p = 0.008); younger patients (aged

This study explored heterogeneous treatment effects (HTEs) of the real-world use of dipeptidyl peptidase-4 inhibitors (DPP-4is) vs. sulfonylureas (SUs) on cardiovascular diseases (CVDs) and mortality in patients with type 2 diabetes. Utilizing Taiwan's National Health Insurance Research Database, 19,853 propensity score-matched pairs of DPP-4i and SU stable users were identified. Classification and regression tree analyses and Cox models were applied to explore HTEs, according to various patient characteristics, on the composite CVDs, three-point major adverse cardiovascular event (MACE), and all-cause mortality. The absolute risk difference (ARD), hazard ratio (HR), and 95% confidence interval (CI) were estimated for comparing treatment effects. CVD history, ischemic stroke, or transient ischemic attack (IS/TIA) history, and age at treatment initiation were significant treatment effect modifiers. Patients with prior IS/TIA but without any other prior CVDs benefited most in reduced risks of composite CVDs from using DPP-4i vs. SU (ARD -4.31%, 95% CI -7.48% to -1.14%, HR 0.81, 95% CI 0.69 ~ 0.95), followed by those without prior IS/TIA and CVDs and initiated with DPP-4i at age

Objectives: We assessed the economic burden of AIDS-defining illnesses (ADIs), which was further stratified by adherence to antiretroviral therapy (ART). Methods and materials: A nationwide longitudinal cohort of 18,234 incident cases with HIV followed for 11 years was utilized. Adherence to ART was measured by medication possession ratio (MPR). Generalized estimating equations modeling was used to estimate the cost impact of ADIs. Results: Having opportunistic infections increased the annual cost by 9% (varicella-zoster virus infection) to 98% (cytomegalovirus disease), while the annual costs increased by 26% (Kaposi’s sarcoma) to 95% (non-Hodgkin’s lymphoma) in the year when AIDS-related cancer occurred. ADIs occurred more frequently in the years with low adherence for ART compared to the high-adherence years (e.g., 0.1 ≤ MPR

Recent years have seen a rapidly rising number of oxygenated water brands that claim to impart health benefits and increase athletic performance by improving oxygen availability in the body. Drinks with higher dissolved oxygen concentrations have in recent times gained popularity as potential ergogenic aids, despite the lack of evidence regarding their efficacy. The aim of this study was to characterize oxygenated water and assess the improvement in uric acid metabolism while identifying performance enhancements in animals administered oxygenated water. Oxygenated water was characterized by hydrogen and oxygen nuclear magnetic resonance (NMR) spectroscopy. Hyperuricemia in rats was induced by treatment with oxonic acid potassium salt, and the animals were given oxygenated drinking water before, during, or after oxonic acid treatment. Serum uric acid was measured to confirm the effects on uric acid metabolism. Following oxygenation, the full width at half maximum (FWHM) was reduced to 11.56 Hz and 64.16 Hz in the hydrogen and oxygen NMR spectra, respectively. Oxygenated water molecule clusters were reduced in size due to the reduction in FWHM. Oxygen concentration did not vary significantly with increased temperature. However, standing time played a critical role in the amount of oxygen dissolved in the water. The rat studies indicated that oxygenated water reduced serum uric acid levels and their rate of increase and enhanced uric acid metabolism. A significant improvement in uric acid metabolism and rate of increase in serum uric acid concentration was observed in hyperuricemic rats administered oxygenated water compared to that in rats administered regular water. High oxygen concentrations enhanced the rate of oxygen absorption, leading to increased glycolysis and mitochondrial protein synthesis. Therefore, oxygenated water is a potential adjuvant therapy or health food for treatment of hyperuricemia.

HepG2 cell death with magnetic hyperthermia (MHT) using hydroxyapatite nanoparticles (mHAPs) and alternating magnetic fields (AMF) was investigated in vitro. The mHAPs were synthesized as thermo-seeds by co-precipitation with the addition of Fe(2+). The grain size of the HAPs and iron oxide magnetic were 39.1 and 19.5 nm and were calculated by the Scherrer formula. The HepG2 cells were cultured with mHAPs and exposed to an AMF for 30 min yielding maximum temperatures of 43 ± 0.5 °C. After heating, the cell viability was reduced by 50% relative to controls, lactate dehydrogenase (LDH) concentrations measured in media were three-fold greater than those measured in all control groups. Readouts of toxicity by live/dead staining were consistent with cell viability and LDH assay results. Measured reactive oxygen species (ROS) in cells exposed to MHT were two-fold greater than in control groups. Results of cDNA microarray and Western blotting revealed tantalizing evidence of ATM and GADD45 downregulation with possible MKK3/MKK6 and ATF-2 of p38 MAPK inhibition upon exposure to mHAPs and AMF combinations. These results suggest that the combination of mHAPs and AMF can increase intracellular concentrations of ROS to cause DNA damage, which leads to cell death that complement heat stress related biological effects.

Aims To compare the effects of initiating insulin as a fourth-line antidiabetic therapy with the effects of enhancing oral antidiabetic drug (OAD) therapy in patients with type 2 diabetes mellitus (T2DM) with triple OAD therapy failure. Materials and methods We conducted a nationwide population-based, retrospective cohort study involving 1022 (without prevalent diabetes-related complications [PDRCs]) and 2077 (with/without PDRCs) propensity score-matched pairs of fourth-line insulin therapy users and enhanced OAD therapy users identified in the period 2004 to 2010. Clinical outcomes including a composite cardiovascular outcome (myocardial infarction, stroke, heart failure or ischaemic heart disease), peripheral vascular disease (PVD), hypoglycaemia and all-cause mortality were assessed up to 2013. Hypoglycaemia was adjusted in Cox models to consider its potential effect on study outcomes. Results In a T2DM cohort without PDRCs, fourth-line insulin therapy was not associated with greater risks of clinical outcomes, except hypoglycaemia (hazard ratio [HR] 1.45, 95% confidence interval [CI] 1.02-2.07), compared with enhanced OAD therapy. Among patients with T2DM with/without PDRCs, fourth-line insulin therapy was associated with greater risks of the composite cardiovascular outcome (HR 1.23, 95% CI 1.03-1.46), heart failure (HR 1.59, 95% CI 1.12-2.25), ischaemic heart disease (HR 1.37, 95% CI 1.09-1.73), PVD (HR 1.17, 95% CI 1.00-1.36), hypoglycaemia (HR 1.49, 95% CI 1.20-1.85) and all-cause mortality (HR 1.48, 95% CI 1.01-2.17), but adjustment for hypoglycaemia significantly attenuated the risk of heart failure (HR 1.34, 95% CI 0.92-1.94), PVD (HR 1.15, 95% CI 0.98-1.34) and all-cause mortality (HR 1.30, 95% CI 0.84-1.99). Conclusions Initiation of fourth-line insulin therapy can be considered for patients with T2DM with triple OAD therapy failure, and the importance of awareness and prevention of hypoglycaemia among insulin-treated patients with T2DM cannot be overstated.
