Risk of Hemorrhagic Stroke among Patients Treated with High-Intensity Statins versus Pitavastatin-Ezetimibe: A Population Based Study.

High-intensity statin (HIS) is recommended for high-risk patients in current guidelines. However, the risk of hemorrhagic stroke (HS) with HIS is a concern for Asians. Pitavastatin carries pharmacological differences compared with other statins. We compared the risk of HS in patients treated with pitavastatin-ezetimibe vs. HIS. We conducted a population-based, propensity score-matched cohort study using data from the Taiwan National Health Insurance Research Database. From January 2013 to December 2018, adults (≥ 18 years) who received pitavastatin 2-4 mg/day plus ezetimibe 10 mg/day (combination group, N = 3,767) and those who received atorvastatin 40 mg/day or rosuvastatin 20 mg/day (HIS group, N = 37,670) were enrolled. The primary endpoint was HS. We also assessed the difference of a composite safety endpoint of hepatitis or myopathy requiring hospitalization and new-onset diabetes mellitus. Multivariable Cox proportional hazards model was used to evaluate the relationship between study endpoints and different treatment. After a mean follow-up of 3.05 ± 1.66 years, less HS occurred in combination group (0.74%) than in HIS group (1.35%) [adjusted hazard ratio (aHR) 0.65, 95% confidence interval (CI) 0.44-0.95]. In subgroup analysis, the lower risk of HS in combination group was consistent among all pre-specified subgroups. There was no significant difference of the composite safety endpoint between the 2 groups (aHR 0.91, 95% CI 0.81-1.02). In conclusion, pitavastatin-ezetimibe combination treatment had less HS compared with high-intensity atorvastatin and rosuvastatin. Pitavastatin-ezetimibe may be a favorable choice for Asians who need strict lipid control but with concern of HS.

Dental treatments in patients with special needs provided by university medical center in Southern Taiwan: a retrospective study.

OBJECTIVES: We perform special-need dental treatment at outpatient department (OPD), under general anesthesia (GA) when necessary, and provide domiciliary dental care. We aim to evaluate the profile and the characteristics of special needs patients (SNPs). MATERIALS AND METHODS: We consecutively enrolled 3117 SNPs from January 1, 2019 to December 31, 2022. Eighty patients with rare or genetic diseases were excluded. Demographic data were retrospectively collected. RESULTS: There were totally 3037 SNPs (mean age: 48.2 years; range, 1-100; male-to-female ratio, 1.5); 89.1% (n = 2705) SNPs received dental care at the OPD (OPD-SNPs), 7.9% (n = 239) received dental treatment under GA, and 3.0% (n = 93) received domiciliary dental care. Among those SNPs who received dental treatment under GA (n = 239), 91.2% (n = 218) were mental/intellectual disabled, and most underwent cavity filling (69.5%) and dental extractions (56.5%). OPD-SNPs with mental/intellectual disabilities (n = 1340) received significantly more items of dental treatment than those without (n = 1365). SNPs with more severe disabilities received more fluoride application and ultrasonic scaling (both p < 0.001, trend tests). Interestingly, among OPD-SNPs with mental/intellectual disabilities (n = 1340), more severe patients received more fluoride application (p < 0.001) and ultrasonic scaling (p < 0.001) but fewer root canal treatment (p = 0.007, trend test). CONCLUSIONS: GA benefited SNPs with more dental procedures, including invasive items. SNPs with mental/intellectual disabilities can tolerate more measures and SNPs with more severe mental/intellectual disabilities received more preventive measures but less invasive measures. Similarly, more severe SNPs with other disabilities received more preventive measures but not invasive measures. CLINICAL RELEVANCE: Our findings may provide useful information for special needs dentists and for doctor-patient communication.

Exploring the optimal lower blood pressure boundary during endovascular thrombectomy in patients with large vessel occlusion.

BACKGROUND: Current guidelines advocate for maintaining BP level below 180/105 mmHg during EVT, determining the safe lower boundary remains primarily consensus-driven by experts. This study aims to delve into the correlation between various targets of lower boundary for systolic and diastolic BP (SBP and DBP) during EVT and 3-month functional outcomes. METHODS: A cohort study was conducted across two EVT-capable centers, enrolling patients with large artery occlusion undergoing EVT within 8 h of stroke onset. Mean BP values during EVT were meticulously recorded, and logistic regression models were utilized to evaluate the correlation between outcomes and diverse lower boundary targets for SBP and DBP. Additionally, logistic regression models investigated the relationship between periprocedural BP variability and subsequent outcomes. RESULTS: Among the 201 patients included, having a SBP higher than 130 or 140 mmHg showed an independent association with increased good functional outcomes at 3 months (adjusted odds ratio, aOR 2.80, 95% Cis, 1.26-6.39 for 140 mmHg; aOR 2.34, 95% Cis, 1.03-5.56 for 130 mmHg). Additionally, an SBP exceeding 130 mmHg was correlated with decreased 3-month mortality (aOR, 0.24, 95% CI 0.07-0.74). No significant relationship was observed between DBP and functional outcomes. Patients with higher periprocedural SBP coefficient variance exhibited a decreased rate of good functional outcomes at 3 months (aOR, 0.42, 95% CI, 0.18-0.96). CONCLUSIONS: A SBP range above 130-140 mmHg could potentially serve as a safe lower boundary during EVT, while minimizing BP fluctuations may correlate with improved post-EVT functional outcomes.

Genome-wide association study of age at menarche in the Taiwan Biobank suggests NOL4 as a novel associated gene.

Sexual maturation is a complex physiological process that involves multiple variables, such as genetic and environmental factors. Among females, age at menarche (AM) is a critical milestone for sexual maturation. This study aimed to identify genetic markers of AM using nationwide population cohort data in Taiwan. Females with self-reported AM between 10 and 16 years (N = 39,827) were eligible for the final analysis. To identify genetic signals related to AM, we conducted a genome-wide association study using a linear regression model and split-half meta-analysis method to verify our findings. The Functional Mapping and Annotation web-based platform was used for positional mapping and gene-based and gene-set analyses. The meta-analysis identified four significant loci, i.e., LIN28B (pooled P = 1.39 × 10-21), NOL4 (pooled P = 8.94 × 10-9), GPR45 (pooled P = 4.19 × 10-11), and LOC105373831 (pooled P = 4.37 × 10-8), that were associated with AM. MAGMA gene-based analysis revealed that LIN28B (P = 1.13 × 10-8), NOL4 (P = 2.27 × 10-7), RXRG (P = 4.34 × 10-7), ETV5 (P = 1.75 × 10-6), and HACE1 (P = 1.82 × 10-6) were significantly associated with AM, while the gene-set analysis identified a significantly enriched pathway involving mTOR signaling complex (FDR corrected P = 1.28 × 10-2). The results replicated evidence for several genetic markers associated with AM in the Taiwanese female population. Our analysis identified a novel locus (rs7239368) in NOL4 associated with AM (ß = 0.051 ± 0.009 years, pooled P = 8.94 × 10-9), whereas additional research is needed to validate its molecular role in sexual maturation.

Ubiquitin-specific peptidase 5 facilitates cancer stem cell-like properties in lung cancer by deubiquitinating ß-catenin.

BACKGROUND: Lung cancer has the highest mortality rate in the world, and mounting evidence suggests that cancer stem cells (CSCs) are associated with poor prognosis, recurrence, and metastasis of lung cancer. It is urgent to identify new biomarkers and therapeutic targets for targeting lung CSCs. METHODS: We computed the single-sample gene set enrichment analysis (ssGSEA) of 1554 Reactome gene sets to identify the mRNA expression-based stemness index (mRNAsi)-associated pathways using the genome-wide RNA sequencing data of 509 patients from The Cancer Genome Atlas (TCGA) cohort of lung adenocarcinoma (LUAD). Phenotypic effects of ubiquitin-specific peptidase 5 (USP5) on the CSC-like properties and metastasis were examined by in vitro sphere formation assay, migration assay, invasion assay, and in vivo xenografted animal models. Cycloheximide chase assay, co-immunoprecipitation assay, and deubiquitination assay were performed to confirm the effect of USP5 on the deubiquitination of ß-catenin. RESULTS: We demonstrated that USP5 expression were positively correlated with the stemness-associated signatures and poor outcomes in lung cancer specimens. Silencing of endogenous USP5 reduced CSC-like characteristics, epithelial-mesenchymal transition (EMT), and metastasis in vitro and in vivo. Furthermore, USP5 interacted with ß-catenin, which resulted in deubiquitination, stabilization of ß-catenin, and activation of Wnt/ß-catenin pathway. Accordingly, expression of USP5 was positively correlated with the enrichment score of the Wnt/TCF pathway signature in human lung cancer. Silencing of ß-catenin expression suppressed USP5-enhancing sphere formation. Targeting USP5 with the small molecule WP1130 promoted the degradation of ß-catenin, and showed great inhibitory effects on sphere formation, migration, and invasion. Finally, we identified a poor-prognosis subset of tumors characterized by high levels of USP5, Wnt signaling score, and Stemness score in both TCGA-LUAD and Rousseaux_2013 datasets. CONCLUSIONS: These findings reveal a clinical evidence for USP5-enhanced Wnt/ß-catenin signaling in promoting lung cancer stemness and metastasis, implying that targeting USP5 could provide beneficial effects to improve lung cancer therapeutics.

Prediction of incidence of neurological disorders in HIV-infected persons in Taiwan: a nested case-control study.

BACKGROUND: Neurological disorders are still prevalent in HIV-infected people. We aimed to determine the prevalence of neurological disorders and identify their risk factors in HIV-infected persons in Taiwan. METHODS: We identified 30,101 HIV-infected people between 2002 and 2016 from the National Health Insurance Research Database in Taiwan, and analyzed the incidence of neurological disorders. We applied a retrospective, nested case-control study design. The individuals with (case group) and without (control group) a neurological disorder were then matched by age, sex and time. Factors associated with neurological disorders were analyzed using a conditional logistic regression model, and a nomogram was generated to estimate the risk of developing a neurological disorder. RESULTS: The incidence of neurological disorders was 13.67 per 1000 person-years. The incidence remained stable during the observation period despite the use of early treatment and more tolerable modern anti-retroviral therapy. The conditional logistic regression model identified nine clinical factors and comorbidities that were associated with neurological disorders, namely age, substance use, traumatic brain injury, psychiatric illness, HIV-associated opportunistic infections, frequency of emergency department visits, cART adherence, urbanization, and monthly income. These factors were used to establish the nomogram. CONCLUSION: Neurological disorders are still prevalent in HIV-infected people in Taiwan. To efficiently identify those at risk, we established a nomogram with nine risk factors. This nomogram could prompt clinicians to initiate further evaluations and management of neurological disorders in this population.

Preterm birth and weight-for-gestational age for risks of autism spectrum disorder and intellectual disability: A nationwide population-based cohort study.

PURPOSE: To evaluate gestational age (GA) and small-for-gestational age (SGA) as continuums and gender on the incidences of autism spectrum disorder (ASD) and co-occurring intellectual disability (ID). METHODS: This is a population-based cohort study using the 2004-2008 Taiwan Maternal and Child Health Database. The diagnosis of ASD was determined by International Classification of Diseases, 9th Revision (ICD-9). Generalized estimating equations models were fit to evaluate associations between perinatal variables and ASD. RESULTS: This study included 916,315 individuals. A total of 9474 (1.0%) children were diagnosed with ASD, among whom 1594 (16.8%) had co-occurring ID. Lower GA carried higher odds of ASD with ID (GA < 28 weeks, aOR: 4.26, 95% CI: 2.13, 8.50; GA 28-30 weeks, aOR: 2.80, 95% CI: 1.57, 4.97; GA 31-33 weeks, aOR: 1.63, 95% CI: 1.05, 2.55; GA 34-36 weeks, aOR: 1.39, 95% CI: 1.16, 1.67) and ASD without ID (GA < 28 weeks, aOR:2.05, 95% CI: 1.25, 3.36; GA 28-30 weeks, aOR: 2.02, 95% CI: 1.46, 2.79; GA 31-33 weeks, aOR: 1.42, 95% CI: 1.13, 1.77; GA 34-36 weeks, aOR: 1.18, 95% CI: 1.08, 1.29). Male preterm infants had ASD risks negatively correlated to GA, while ASD risks were significantly increased only among female infants born late preterm. The degree of SGA showed a stepwise increased risk for ASD with and without ID in both male and female infants. CONCLUSION: Lower GA and the degree of SGA are both associated with ASD susceptibility, either with or without co-occurring ID, and remarkably increased the risk of ID.

The Effects of Post-Acute Care in Patients with Heart Failure in Taiwan: A Single Center Experience.

Background: The National Health Insurance Administration in Taiwan has promoted the heart failure post-acute care (HF-PAC) program as a means to provide proactive integrated care within the optimal treatment timeframe to enhance functional recovery after acute decompensated heart failure (HF). Objectives: The aim of this program was to reduce HF readmission rates, improved medication prescription rates, and improve the quality of life in HF patients. Methods: Patients who had a reduced left ventricular ejection fraction (LVEF) of ≤ 40% were included and followed up for 6 months after discharge. They underwent cardiac rehabilitation and physiological, and nutritional status evaluations. The main clinical outcomes of the HF-PAC program were guideline-directed medical therapy prescription rate and 6-month readmission rate. Results: A total of 122 patients were recruited from June 2018 to December 2020 at a medical center in southern Taiwan. The patients' activities of daily living, nutritional status, quality of life and LVEF were significantly improved during the HF-PAC program. More than 95% of the patients received guideline-directed medical prescriptions at the end of the HF-PAC program. The cardiovascular-related 6-month re-admission rate after the HF-PAC program ended was 27.7%, and it could be predicted by the New York Health Association functional class [hazard ratio (HR) 95% confidence interval (95% CI) = 4.12 (1.36-12.46)], value of the Mini Nutritional Assessment - Short Form [HR (95% CI) = 0.46 (0.31-0.68)] and LVEF [HR (95% CI) = 0.95 (0.91-0.99)]. Conclusions: By incorporating multidisciplinary healthcare teams, the HF-PAC program improves the guideline- directed medical therapy prescription rate, thus improving patients' cardiac function, physical activity recovery, the quality of life, and also reduces their readmission rate.

Profiling antibody signature of schizophrenia by Escherichia coli proteome microarrays.

Schizophrenia (SZ) is influenced by genetic and environmental factors, and associated with chronic neuroinflammation. If the symptoms express after adolescence, environmental impacts are more substantial, and the disease is defined as adult-onset schizophrenia (AOS). Effects of environmental factors on antibody responses such as Escherichia coli (E. coli) to immunoglobulin G (IgG) and immunoglobulin M (IgM) might increase the severity of symptoms in SZ via the gut-brain axis. The purpose of this study is to reveal antibody profiles of SZ against bacterial protein antigens. We analyzed the IgG and IgM antibodies using E. coli proteome microarrays from 80 SZ patients and 40 healthy controls (HC). Using support vector machine to select panels of proteins differentiating between groups and conducted enrichment analysis for those proteins. We identified that the groL, pldA, yjjU, livG, and ftsE can classify IgGs in AOS vs HC achieved accuracy of 0.7. The protein yjjU, livG and ftsE can form the best combination panel to classify IgG in AOS vs HC with accuracy of 0.8. The enrichment results are highly related to ABC (ATP binding cassette) transporter in the protein domain and cellular component. We further found that the human ATP binding cassette subfamily b member 1 (ABCB1) autoantibody level in AOS is significantly higher than in HC. The findings suggest that AOS had different immunoglobulin production compared to early-onset schizophrenia (EOS) and HC. We also identified potential antibody biomarkers of AOS and found their antigens are enriched in ABC transporter related domains, including human ABCB1 protein.

Maternal Th17/Treg Cytokines and Small Extracellular Vesicles in Plasma as Potential Biomarkers for Preeclampsia.

Preeclampsia is one of the most serious pregnancy complications. It may be caused by immunological changes in the early placental microenvironment. The contents of small EVs may serve as biomarkers of pregnancy complications. Evidence suggests that the balance between T helper 17 (Th17) and regulatory T (Treg) cells are critical for preventing preeclampsia. The study recruited 39 pregnant women with preeclampsia and 127 healthy pregnant women. We assessed the levels of both Th17 and Treg cytokines (IL-10, IL-17, IL-21, IL-22, and TGF-ß) in their plasma and small EVs. We found significant differences in the levels of all cytokines in the plasma between the two groups during the second trimester. We also observed significant differences between the two groups in the levels of EV-encapsulated cytokines IL-21, IL-22, and TGF-ß, as well as in total small EVs, during the second trimester. The ROC analysis showed that the classification efficiency (AUC) of TGF-ß in small EVs was 0.81. TGF-ß had the best discriminant ability of all the single EV biomarkers tested, the cross-validation of the accuracy was 0.89. Th17 and Treg cytokines in plasma and small EVs may contribute to maternal immune activation and clarify the potential mechanisms of small EVs and cytokines in preeclampsia.

Typical antipsychotics is associated with increased risk of severe exacerbation in asthma patients: a nationwide population-based cohort study.

BACKGROUND: Severe asthma exacerbation reduces patients' quality of life, results in visits to the emergency department (ED) and hospitalization, and incurs additional medical costs. Antipsychotics block receptors with bronchodilation function; however, the association between antipsychotic use and severe asthma exacerbation is unknown. This study aimed to investigate the effects of antipsychotics on asthma-related ED visits and hospitalizations. METHODS: A case-crossover design was used in this study. Using the 2003-2017 Taiwan National Health Insurance Reimbursement Database, we established a cohort of 18,657 adults with asthma exacerbation leading to ED visits or hospitalization. Univariate and multivariate conditional logistic regressions were conducted to explore the association between antipsychotic use and severe asthma exacerbation. Subgroup analyses of different classes, doses, receptor functions of antipsychotics, different psychiatric disease, and sensitivity analyses of excluding patients with schizophrenia were also performed. RESULTS: Antipsychotic use was associated with a higher risk of severe asthma exacerbation (adjusted odds ratio [OR]: 1.27; 95% confidence interval [CI] 1.05-1.54; P = 0.013) compared with no use of antipsychotics. The use of typical antipsychotics increased the risk of severe asthma exacerbation (adjusted OR: 1.40, 95% CI 1.10-1.79, P = 0.007), whereas the use of atypical antipsychotics did not. These results did not change after the exclusion of patients with schizophrenia. There was a dose-dependent effect of antipsychotics (trend test, P = 0.025). Antipsychotics that block the M2 muscarinic or D2 dopaminergic receptors were associated with an increased risk of severe asthma exacerbation (adjusted OR: 1.39, 95% CI 1.10-1.76, P = 0.007 and adjusted OR: 1.33, 95% CI 1.08-1.63, P = 0.008, respectively). However, use of antipsychotics did not increase risk of severe asthma exacerbation in patients with psychiatric disorder. CONCLUSIONS: The use of typical antipsychotics is associated with a dose-dependent increased risk of severe asthma exacerbation, especially for patients without psychiatric disorders. Further research on the impact of typical antipsychotics on asthma exacerbation is warranted.

Detailed risks and characteristics of postepilepsy stroke in non-traumatic adult-onset epilepsy.

BACKGROUND: Patients with epilepsy have an increased risk of stroke. However, the detailed risk and characteristics of postepilepsy stroke have not been investigated. METHODS: This study utilized the National Health Insurance Research Database in Taiwan. We classified adult patients with newly diagnosed epilepsy from 2003 to 2016 as the epilepsy cohort. Patients in the nonepilepsy cohort were selected with propensity score matching at a case-control ratio of 1:5. The incidence, hazard ratio (HR), period-specific HR, recurrent HR in the Wei-Lin-Weissfeld model, stroke severity index, complications, and mortality of all stroke, ischemic stroke (IS) and hemorrhagic stroke events in the two cohorts were analyzed. RESULTS: We enrolled 23,810 patients in the epilepsy cohort and 119,050 persons in the nonepilepsy cohort. The period-specific HRs of all stroke, IS and hemorrhagic stroke peaked immediately after epilepsy diagnosis and trended downward [Adjusted HRs of all stroke: 4.88 (3.88-6.14), 4.47 (3.50-5.70), 3.17 (2.62-3.84), 2.81 (2.27-3.48), 2.81 (2.36-3.34) and 2.33 (2.07-2.62) in 0-0.5, 0.5-1, 1-2, 2-3, 3-5 and ≥5 years after epilepsy diagnosis, respectively]. The recurrent stroke HRs in the epilepsy cohort were >1 from the first [3.06 (2.71-3.34)] to the fourth events [6.33 (1.08-37.03)]. IS events in the epilepsy cohort were associated with a younger onset age, a higher IS severity index, a higher rate of urinary tract infection, a lower in-hospital mortality, while 90-day stroke mortality was similar between the 2 cohorts. CONCLUSION: Since the increased risk of stroke in epilepsy cohort peaked immediately after epilepsy diagnosis, early implementation of prevention strategies is considered.

Baseline plasma KL-6 level predicts adverse outcomes in patients with idiopathic pulmonary fibrosis receiving nintedanib: a retrospective real-world cohort study.

BACKGROUND: Nintedanib is effective for treating idiopathic pulmonary fibrosis (IPF), but some patients may exhibit a suboptimal response and develop on-treatment acute exacerbation (AE-IPF), hepatic injury, or mortality. It remains unclear which patients are at risk for these adverse outcomes. METHODS: We analysed the demographic and clinical data, baseline plasma levels of Krebs von den Lungen-6 (KL-6) and surfactant protein A (SPA), and longitudinal clinical courses of a real-world cohort of IPF patients who received nintedanib ≥ 14 days between March 2017 and December 2020. Cox proportional-hazards regression, subdistribution hazards regression, and sensitivity analyses were performed to investigate the association between baseline predictors and AE-IPF, mortality, and nintedanib-related hepatic injury. The relationship between baseline predictors and pulmonary function decline was determined. RESULTS: Fifty-seven patients were included, of whom 24 (42%) developed hepatic injury, 20 (35%) had AE-IPF, and 16 (28%) died on-treatment. A baseline plasma KL-6 level ≥ 2.5 ng/mL, and diffusion capacity for carbon monoxide (DLCO) < 55% predicted, were associated with increased risk of hepatic injury (adjusted hazard ratio [aHR] was 3.46; 95% CI 1.13-10.60; p = 0.029 for KL-6, and 6.05; 95% CI 1.89-19.32; p = 0.002 for DLCO). Both factors also predicted severe and recurrent hepatic injury. Patients with baseline KL-6 ≥ 2.5 ng/mL also had a higher risk of AE-IPF (aHR 4.52; 95% CI 1.63-12.55; p = 0.004). For on-treatment mortality, baseline KL-6 ≥ 3.5 ng/mL and SPA ≥ 600 pg/mL were significant predictors (aHR 5.39; 95% CI 1.16-24.97; p = 0.031 for KL-6, and aHR 12.28; 95% CI 2.06-73.05; p = 0.006 for SPA). Results from subdistribution hazard regression and sensitivity analyses supported these findings. Patients with elevated baseline plasma KL-6 levels also exhibited a trend towards faster pulmonary function decline. CONCLUSIONS: For patients with IPF who are receiving nintedanib, we have identified baseline predictors, in particular plasma KL-6 levels, for the risk of adverse outcomes. Patients with these predictors may require close monitoring for unfavourable responses during treatment. Our findings also support the prognostic role of molecular markers like KL-6 and may contribute to future formulation of more individualized therapeutic strategies for IPF.

Reduced-Dose Prasugrel versus Clopidogrel for Patients Undergoing Percutaneous Coronary Intervention.

Whether reduced-dose prasugrel has a better efficacy or safety than standard-dose clopidogrel remains unknown in patients undergoing percutaneous coronary intervention (PCI).A systematic search of PubMed, EMBASE, Google Scholar, and Cochrane Library from database inception to May 1, 2020 was performed to compare the clinical outcomes in patients with acute coronary syndrome or stable coronary artery disease undergoing PCI between those treated with reduced-dose prasugrel and clopidogrel. The pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using the fixed-effect or random-effect model if significant heterogeneity was observed. The primary efficacy endpoint was major adverse cardiovascular events (MACE), including cardiovascular (CV) death, myocardial infarction (MI), or ischemic stroke. The primary safety endpoint was all bleeding events.Overall, seven studies with 32,951 patients with PCI were included in the analysis. Reduced-dose prasugrel was associated with a lower risk of MACE than clopidogrel (OR 0.80, 95% CI 0.67-0.97). Except for MI (OR 0.74, 95% CI 0.56-0.98), the secondary efficacy endpoints of CV death, ischemic stroke, all-cause death, and stent thrombosis were similar. For the primary safety endpoint of all bleeding events, there was no significant difference between reduced-dose prasugrel and clopidogrel (OR 1.31, 95% CI 0.87-1.98), but the risk of minor bleeding was significantly higher in reduced-dose prasugrel (OR 1.73, 95% CI 1.25-2.41).In patients undergoing PCI, a lower risk of MACE was found in patients receiving reduced-dose prasugrel than in those with clopidogrel, but a higher risk of minor bleeding events was noted.

Commercial Cu2 Cr2 O5 Decorated with Iron Carbide Nanoparticles as a Multifunctional Catalyst for Magnetically Induced Continuous-Flow Hydrogenation of Aromatic Ketones.

Copper chromite is decorated with iron carbide nanoparticles, producing a magnetically activatable multifunctional catalytic system. This system (ICNPs@Cu2 Cr2 O5 ) can reduce aromatic ketones to aromatic alcohols when exposed to magnetic induction. Under magnetic excitation, the ICNPs generate locally confined hot spots, selectively activating the Cu2 Cr2 O5 surface while the global temperature remains low (≈80 °C). The catalyst selectively hydrogenates a scope of benzylic and non-benzylic ketones under mild conditions (3 bar H2 , heptane), while ICNPs@Cu2 Cr2 O5 or Cu2 Cr2 O5 are inactive when the same global temperature is adjusted by conventional heating. A flow reactor is presented that allows the use of magnetic induction for continuous-flow hydrogenation at elevated pressure. The excellent catalytic properties of ICNPs@Cu2 Cr2 O5 for the hydrogenation of biomass-derived furfuralacetone are conserved for at least 17 h on stream, demonstrating for the first time the application of a magnetically heated catalyst to a continuously operated hydrogenation reaction in the liquid phase.

Changing Treatment Patterns in Patients With Venous Thromboembolism in Taiwan.

BACKGROUND: In Asia, little information is available about contemporary real-world treatment patterns for venous thromboembolism (VTE).Methods and Results:Consecutive patients (n=11,414) from the Taiwan National Health Insurance Research Database with initial VTE and taking oral anticoagulants between May 1, 2014 and June 30, 2016 were included. The temporal trends of using oral anticoagulants and pharmacomechanical therapy during the study period were evaluated. The efficacy and safety of nonvitamin K antagonist oral anticoagulants (NOACs) vs. warfarin were compared. Propensity score analysis (NOACs n=3,647 vs. warfarin n=3,647) was used to balance covariates between groups, and Cox proportional hazards models with adjustment were used to estimate the risks of clinical outcomes. The use of NOACs increased from 0.3% to 60.2% for VTE treatment during the study period. Pharmacomechanical therapy was used in 9.60%, 8.22%, and 5.63% from 2014 through 2016. NOACs were associated with a 16% risk reduction (adjusted hazard ratio [aHR] 0.84, 95% confidence interval [CI] 0.77-0.93) in all-cause mortality and a 21% risk reduction (aHR 0.79, 95% CI 0.65-0.96) in recurrent VTE vs. warfarin. Overall, NOACs were associated with a lower risk of major bleeding compared with warfarin (aHR 0.804, 95% CI 0.648-0.998). CONCLUSIONS: In real-world practice, NOACs have become the major anticoagulant used for Asians with VTE. Although NOACs had a lower risk of recurrent VTE and major bleeding compared with warfarin in Taiwan, we still need a large-scale randomized controlled trial to confirm the findings.

Alterations of plasma cytokine biomarkers for identifying age at onset of schizophrenia with neurological soft signs.

Several studies have been suggested that immunity plays a part in neurodevelopment and schizophrenia pathogenesis. Early age of onset in schizophrenia is associated with genetic factors which affect neurodevelopment. This study aims to identify immune abnormalities associated with neurodevelopmental impairments in early-onset schizophrenia (EOS) and adult-onset schizophrenia (AOS) patients. We determined the plasma levels of six cytokines (IL-1ß, IL-4, IL-6, IL-10, IL-12 and TNF-α) in schizophrenia patients and healthy controls. Measurements included neurological soft signs (NSS) to distinguish and subgroup those with neurodevelopmental impairments. The study included 210 schizophrenia patients, which were divided into 84 EOS and 126 AOS patients, as well as 122 healthy controls. We observed significant differences in levels of IL-4, IL-6 and IL-10 between EOS and AOS patients. The results demonstrated the area under ROC curve (AUC) of the IL-4 in EOS and healthy controls was 0.81. Moreover, these results indicated that AUC of the IL-4 and the combination of IL-4, IL-6 and IL-12 in EOS with NSS and healthy controls were 0.91 and 0.95. These cytokines are altered in EOS and schizophrenia patients with neurodevelopmental impairments and demonstrated good classification abilities. These findings manifested that both pro- and anti-inflammatory cytokines are contributed to the clinical and pathophysiological features of schizophrenia. Future works are expected to explore potential genetic effectors and predictors as well as therapeutic directions in personalized medicine for early-onset schizophrenia.

Prognostic Value of the Overexpression of Fatty Acid Metabolism-Related Enzymes in Squamous Cell Carcinoma of the Head and Neck.

Reprogramming of cellular energy metabolism, such as lipid metabolism, is a hallmark of squamous cell carcinoma of the head and neck (SCCHN). However, whether protein expression related to fatty acid oxidation (FAO) affects survival in SCCHN remains unclear. We aimed to investigate FAO-related enzyme expression and determine its correlation with clinicopathological variables in SCCHN patients. Immunohistochemical analysis (IHC) of FAO-related protein expression, including carnitine palmitoyltransferase 1 (CPT1), the acyl-CoA dehydrogenase family, and fatty acid synthase (FAS), was performed using tissue microarrays from 102 resected SCCHN tumors. Expressions were categorized according to IHC scores, and the statistical association with clinicopathological factors was determined. Moderate-to-high expression of long-chain acyl-CoA dehydrogenase (LCAD) had a protective role against cancer-related death (adjusted hazard ratio (HR), 0.2; 95% confidence interval (CI), 0.05-0.87) after covariate adjustment. Age and clinical stage remained independent predictors of survival (adjusted HR, 1.75; 95% CI, 1.22-2.49 for age; adjusted HR, 14.33; 95% CI, 1.89-108.60 for stage III/IV disease). Overexpression of medium-chain acyl-CoA dehydrogenase and FAS correlated with advanced tumor stage (T3/T4); however, none of these factors were independent predictors of survival. Several FAO-related enzymes were upregulated and LCAD overexpression had a protective effect on overall survival in advanced SCCHN patients. FAO-related-enzyme expression might have a prognostic impact on survival outcomes in SCCHN.

Bidirectional relationship between systemic lupus erythematosus and non-Hodgkin's lymphoma: a nationwide population-based study.

OBJECTIVES: We conducted this nationwide population-based study in Taiwan to investigate whether there is a bidirectional relationship between SLE and non-Hodgkin's lymphoma (NHL). METHODS: Using the National Health Insurance Research Database of Taiwan, we identified 16 417 patients with new-onset SLE without previous cancer and 25 069 patients with new-onset NHL without previous SLE as two non-overlapping cohorts from 1998-2012, and followed them until 2013. Standardized incidence ratio (SIR) for NHL in the patients with SLE and SIR for SLE in the patients with NHL were compared with the general population. RESULTS: Among the 16 417 patients with SLE, 512 developed cancers, including 34 with NHL. The highest SIR was that for NHL (SIR 4.2, 95% CI 2.9, 5.9) in site-specific cancer risk analysis. Among the 25 069 patients with NHL, 14 developed SLE, and the SIR was also increased (SIR 2.0, 95% CI 1.1, 3.4). The SIRs of the patients with SLE to develop NHL and the patients with NHL to develop SLE were both highest within the first year after the diagnosis of each disease. CONCLUSION: This nationwide population-based study is the first study to report a bidirectional relationship between SLE and NHL. This finding may suggest being alert for the patients with SLE or NHL who have early sings of the other disease in clinical care.

Subsequent thyroid disorders associated with treatment strategy in head and neck cancer patients: a nationwide cohort study.

BACKGROUND: We investigated the risk of thyroid disorders, namely hypothyroidism, thyrotoxicosis and thyroiditis, in head and neck cancer patients undergoing multimodal treatment. METHODS: A cohort study design using Taiwan's National Health Insurance Research Database was used to assess head and neck cancer patients over 20 years old. The cohort was divided into one group who underwent primary tumor excision only (PTE) and another with additional neck dissection (PTE + ND). The tumor sites were stratified to estimate the tumor-site-specific risk of thyroid disorders. The effect of subsequent resurgery, radiotherapy (RT), chemotherapy (CT), and concomitant (CCRT) or sequential chemoradiation therapy (sequential CT+ RT) on the risk of thyroid disorders was explored. RESULTS: For 1999-2012, 7460 patients who underwent PTE + ND and 3730 who underwent PTE were enrolled and followed-up until the end of 2013. There were 122 and 50 patients in the two groups, respectively, who developed thyroid disorders, with no statistical difference between the groups. Patients with hypopharyngeal, oropharyngeal, or laryngeal cancer in the PTE + ND group had a higher risk of thyroid disorders (adjusted HR: 1.50, 95% CI: 0.67-3.38) than those in the PTE group when adjusted for covariates and mortality. Patients who underwent subsequent RT (adjusted HR: 3.64, 95% CI: 1.05-2.77) and CCRT (adjusted HR: 1.70, 95% CI: 1.05-2.77) after PTE + ND had a significantly higher risk of thyroid disorders. CONCLUSION: RT results in a major risk of subsequent thyroid disorders, and ND may exacerbate this effect. Physicians should monitor thyroid function from two years after treatment initiation, especially in patients who undergo ND and subsequent RT.
