To compare the tunnel transposition and elevation transposition methods used for superficialization of the basilic vein in terms of complication and patency rates.This retrospective study included patients who underwent 2-stage basilic vein transposition between August 2016 and December 2019. Patients were categorized into brachial-basilic fistula tunnel transposition (n = 32) and elevation transposition (n = 21) groups using medical records. Primary patency was defined as a conduit that remains patent without any re-intervention to maintain patency. Primary assisted patency was defined as a conduit that has undergone intervention to maintain patency but has never been thrombosed.The distribution of baseline characteristics was similar between the 2 groups. Coronary artery disease was the only variable that was significantly different between the tunnel transposition and elevation transposition groups (31.1% vs. 4.8%, P = 0.035). The tunnel transposition group had a greater amount of blood loss (P0.001) and a longer period of hospitalization (P = 0.002) than the elevation transposition group. The rates of suture repair to stop bleeding from the conduit was significantly different between the tunnel transposition and elevation transposition groups (31.8% vs. 4.8%, P = 0.035), whereas those of other complications were not significantly different. The elevation transposition group had a significantly higher primary patency rate than the tunneled transposition group (P = 0.033); however, primary assisted patency was achieved in all patients (100%) in both groups.Elevation transposition might be a more reliable method than tunnel transposition for superficialization of a basilic venous fistula.

Exclusively breastfed infants are at a high risk of vitamin D deficiency. Few studies have evaluated the effects of vitamin D supplementation. Hence, we conducted a prospective randomized controlled trial investigating the effects of oral vitamin D3 400 IU/d supplementation in exclusively breastfed newborns. Serum 25-hydroxy-vitamin D (25[OH]D) levels in pregnant women and their newborns were evaluated. Breastfed newborns were randomized to one of two regimens at age 10 days. One group received vitamin D3 supplementation at a dose of 400 IU/d (vD-400 group), whereas the placebo group received a liquid product without vitamin D3. Outcomes were assessed at 4 months of age. A total of 92 pregnant women and their infants were enrolled, and the data of 72 infants (37 in the vD-400 group and 35 in the placebo group) who completed the study at 4 months of age were assessed. The results showed severe vitamin D deficiency in 15.2% of mothers before delivery, while 54.3% had vitamin D deficiency. Moreover, 15.2% of newborns presented with severe vitamin D deficiency at birth, while 52.2% had vitamin D deficiency. Maternal vitamin D levels were significantly correlated with infant vitamin D levels at birth (r = 0.816, p 0.001). At 4 months of age, weight, head circumference, serum 25(OH)D, phosphorus, and intact parathyroid hormone levels significantly differed between the vD-400 and placebo groups. However, the body length and bone mineral density of the two groups did not differ significantly. Regardless of vitamin D supplementation, participants with severe vitamin D deficiency had significantly higher intact parathyroid hormone levels and lower bone mineral content. In conclusion, among exclusively breastfed infants, oral supplementation with vitamin D3 at a dose of 400 IU/d from age 10 days increased 25(OH)D concentrations at 4 months of age, but it did not affect bone mineralization. © 2022 The Authors.

Background and Purpose: Data on clinical outcomes for nonvitamin K antagonist oral anticoagulant (NOACs) and warfarin in patients with atrial fibrillation and cancer are limited, and patients with active cancer were excluded from randomized trials. We investigated the effectiveness and safety for NOACs versus warfarin among patients with atrial fibrillation with cancer. Methods: In this nationwide retrospective cohort study from Taiwan National Health Insurance Research Database, we identified a total of 6274 and 1681 consecutive patients with atrial fibrillation with cancer taking NOACs and warfarin from June 1, 2012, to December 31, 2017, respectively. Propensity score stabilized weighting was used to balance covariates across study groups. Results: There were 1031, 1758, 411, and 3074 patients treated with apixaban, dabigatran, edoxaban, and rivaroxaban, respectively. After propensity score stabilized weighting, NOAC was associated with a lower risk of major adverse cardiovascular events (hazard ratio, 0.63 [95% CI, 0.50–0.80]; P =0.0001), major adverse limb events (hazard ratio, 0.41 [95% CI, 0.24–0.70]; P =0.0010), venous thrombosis (hazard ratio, 0.37 [95% CI, 0.23–0.61]; P P =0.0171) compared with warfarin. The outcomes were consistent with either direct thrombin inhibitor (dabigatran) or factor Xa inhibitor (apixaban, edoxaban, and rivaroxaban) use, among patients with stroke history, and among patients with different type of cancer and local, regional, or metastatic stage of cancer ( P interaction >0.05). When compared with warfarin, NOAC was associated with lower risk of major adverse cardiovascular event, and venous thrombosis in patients aged P interaction Conclusions: Thromboprophylaxis with NOACs rather than warfarin should be considered for the majority of the atrial fibrillation population with cancer.

BACKGROUND/AIM The clinical significance of frailty status on treatment outcome in patients with esophageal cancer (EC) has been seldom explored. This study aimed to evaluate the impact of pretreatment frailty on treatment-related toxicity and survival outcome in patients with EC undergoing concurrent chemoradiotherapy (CCRT). PATIENTS AND METHODS Patients aged ≥20 years and with newly diagnosed locally advanced EC receiving neoadjuvant radiotherapy and concurrent chemotherapy with weekly administration of carboplatin and paclitaxel for 5 weeks were prospectively enrolled. A pretreatment frailty assessment was performed within 7 days before CCRT initiation. The primary endpoint was treatment-related toxicity and complications of CCRT while the secondary endpoint was overall survival. RESULTS A total of 87 patients were enrolled, 41 (47%) and 46 (53%) of whom were allocated in the frail and fit group, respectively. Frail patients had a significantly higher incidence of having at least one severe hematological adverse event (63.4% vs. 19.6%, p

While serous cystadenomas of the pancreas usually consist of small cysts, one rare variant has been reported to be composed of macrocysts. Herein, we present the case of the youngest patient with macrocystic serous cystadenoma (MSC) to be reported in the literature. The patient was a 17-year-old girl who presented with the major symptoms of a palpable abdominal mass accompanied by epigastric pain and vomiting for several months. A potential malignancy could not be excluded on the basis of imaging studies, which showed a large macrocystic pancreatic tumor that was 7 cm in diameter. Owing to the patient’s symptoms, after diagnosing the mass as a pancreatic cystic tumor with potential malignancy and large tumor size, surgical intervention was arranged. Pathological analysis of the biopsy sample suggested MSC. By reviewing the literature, we found several unique characters of MSCs that cause them to be frequently misdiagnosed as potential malignancies. Additionally, the age of MSC occurrence was found to be lower than of general serous cystadenomas. The potential of MSC should be kept in mind by clinicians when diagnosing young people with pancreatic macrocystic lesions.

Adjuvant concurrent chemoradiotherapy (CCRT) is the standard care for patients with resected advanced gastric cancer, but its survival benefits remain undetermined in patients undergoing D2 lymph node dissection (D2 dissection). We evaluated safety and efficacy of adjuvant CCRT with 5-fluorouracil (5-FU) versus chemotherapy alone in 110 gastric cancer patients with D2 dissection treated in Taiwan between January 2009 and January 2013. All the 71 patients receiving adjuvant CCRT were treated with daily infusional 5-FU and radiotherapy. Adjuvant CCRT was associated with higher risks of major hematologic (56.3% vs. 23.8%, p = 0.002) and gastrointestinal (46.9% vs. 14.3%, p = 0.027) toxicities and death (12.5% vs. 0.0%, p = 0.041) in patients above 70 years old, but this was not the case in those ≤70 years of age. Univariate Cox proportional regressions identified adjuvant CCRT as a factor for better overall survival (OS) (hazard ratio [HR]=0.52; 95% confidence interval [CI]: 0.27–0.99) and disease-free survival (DFS) (HR=0.46, 95% CI: 0.24–0.88), but it was not a significant factor for OS or DFS after adjusting for other factors in the multivariate analysis. However, in stratified analyses by age, we found adjuvant CCRT was an independent prognostic factor for better OS (HR=0.07; 95% CI: 0.01–0.38) in patients ≤70 years old, but not in those above 70 years of age. Therefore, it was concluded that age may to be a modifier of the effects of adjuvant CCRT.

Background: The Glasgow Prognostic Score and circulating cytokine levels are related to the prognosis of colorectal cancer and the severity of chronic inflammation. The association between the Glasgow Prognostic Score and circulating cytokines in colorectal cancer remains unclear. Methods: The levels of 10 circulating cytokines (TNF-α, TGF-β, IFN-γ, IL-1β, IL-4, IL-6, IL-10, IL-12, IL-13, and IL-23) were measured in 128 patients with colorectal cancer. The relationship between the Glasgow Prognostic Score, clinicopathologic variables, and cytokine levels was assessed by univariate and multivariate logistic regression analyses. The correlation among cytokines was also examined. Results: Patients with advanced stage colorectal cancer had lower levels of albumin ( P = 0.003), higher levels of C-reactive protein (CRP; P < 0.001), carcinoembryonic antigen (CEA; P < 0.001), interferon (IFN)-γ ( P < 0.001), and interleukin (IL)-10 ( P = 0.006), and shorter survival outcomes ( P < 0.001). Patients with a high Glasgow Prognostic Score (1 or 2) had lower 5-year progression-free survival and poor overall survival (log-rank P < 0.001). A high Glasgow Prognostic Score was significantly correlated with abnormal CEA levels (CEA > 5 ng/mL, P = 0.033), and higher levels of tumor necrosis factor (TNF)-α (TNF-α ⩾ 53.9 pg/mL, P = 0.035) and IL-10 (IL-10 ⩾ 75.95 pg/mL, P = 0.008). TNF-α, IFN-γ, IL-1β, IL-4, IL-6, IL-10, IL-13, and IL-23 were significantly correlated with each other (all P < 0.05). Only IL-10 was correlated with abnormal CEA levels ( P < 0.001). Conclusion: The Glasgow Prognostic Score and level of circulating cytokines have an intergroup correlation, and there is a close association among cytokines in colorectal cancer.

Background The incidence of cerebral stroke, including ischemic infarction and intracranial hemorrhage (ICH), increases in patients with nephrotic syndrome (NS). However, the clinical characteristics of patients with NS and stroke remain elusive. We aimed to investigate the clinical presentation and prognosis among patients with NS and ischemic stroke (IS) or ICH. Methods We conducted a population-based retrospective cohort study of patients with NS and acute stroke using the Chang Gung Research Database of Taiwan from January 1, 2001, to December 31, 2017. The participants were recruited from the 7 branches of Chang Gung Memorial Hospital. Results A total of 233 patients with IS and 57 patients with ICH were enrolled. The median age was 60 (52–70) years. The prevalence rates of hyperlipidemia, hyperuricemia, and smoking were higher in IS than in ICH. IS demonstrated lower white blood cell count (7.80 vs. 8.92 × 109/L) and high-sensitivity C-reactive protein level (33.42 vs. 144.10 nmol/L) and higher cholesterol (5.74 vs. 4.84 mmol/L), triglyceride (1.60 vs. 1.28 mmol/L), and albumin (24 vs. 18 g/L) levels compared with ICH. The dependent functional status and 30-day mortality were higher in ICH than in IS. The risk factors for 30-day mortality for patients with NS and stroke were coronary artery disease (CAD), ICH, and total anterior circulation syndrome. The multivariate Cox regression analysis revealed that CAD was positively associated with 30-day mortality in patients with IS (hazard ratio 24.58, 95 % CI 1.48 to 408.90). In patients with ICH, CAD and subarachnoid hemorrhage were positively associated with 30-day mortality (hazard ratio 5.49, 95 % CI 1.54 to 19.56; hazard ratio 6.32, 95 % CI 1.57 to 25.53, respectively). Conclusions ICH demonstrated a higher risk of dependence and 30-day mortality compared with IS in patients with NS. Intensive monitoring and treatment should be applied particularly in patients with NS and ICH.

Nuclear factor erythroid 2-related factor 2 (NFE2L2) plays a critical role in ferroptosis and biogenesis, however, its role in cervical squamous cell carcinoma (CESC) remains unknown. Therefore, in this study, we aimed to determine the role of NFE2L2 in CESC using multiomic analysis.All raw data were downloaded from The Cancer Genome Atlas (TCGA) and further validated in our dataset. NFE2L2 mRNA expression and methylation data on CESC were examined using the Tumor Immune Estimation Resource (TIMER) and University of Alabama at Birmingham Cancer Data Analysis Portal (UALCAN) database resources. NFE2L2 expression was examined in paraffin-embedded tissues from our cohort of 240 samples each of cancerous and non-cancerous tissues. Further, cervical cancer biopsies were genetically validated. TIMER and Tumor-Immune System Interactions Database (TISIDB) were used to analyze the correlation between NFE2L2 and cluster of differentiation 163 (CD163) with co-expressed genes in tumor-infiltrating immune cells.The mRNA and protein levels of NFE2L2 were lower in CESC tissues than they were in adjacent tissues. Importantly, a low NFE2L2 level correlated with poor prognosis in CESC patients. NFE2L2 was specifically expressed in tumor macrophages and correlated with the tumor immune landscape and poor prognosis in the cohort data. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway and Gene Ontology (GO) enrichment analysis showed that co-expressed genes are mainly associated with multiple immune-related pathways. Furthermore, our data analysis revealed that NFE2L2 and macrophage CD163 expression levels were negatively correlated. Interestingly, we discovered multiple NFE2L2 binding sites in promoters of CD163.This study confirmed the novel pyroptosis landscape in CESC, provided a role for NFE2L2 in the tumor microenvironment, and identified prognostic biomarkers for CESC and related immune infiltration.

Background Gallstones are uncommon in infants and children and Asian children are thought to have very low risk. Diagnoses have increased in recent years with the widespread use of ultrasonography (USG). This study aimed to review our experience with risk factors, complications, and treatment of pediatric gallstones in low-incidence populations. Methods We retrospectively reviewed patients younger than 18 years old diagnosed with gallstones using USG between November 2006 and December 2012 in a tertiary referral hospital in Taiwan. Demographic information including age and sex, follow-up period, USG findings, predisposing factors, complications, treatment approaches and outcomes were recorded. Results Ninety-eight children with gallstones diagnosed with USG were enrolled and reviewed in our study. Females comprised 55% of patients, with no specific gender tendency. No risk factor could be identified in 30.8% of patients. The most common risk factors were cephalosporin (CS) use, presence of a choledochal cyst (CC), and spherocytosis. CS use was not associated with a higher dissolution rate. The presence of type IVa CC implied a high rate of gallstone recurrence after Roux-en-Y hepaticojejunostomy. Complications were seen in 22.4% of patients, but only two needed emergency stone removal. Expectant management was performed in 61% of patients and 62.5% of them achieved spontaneous resolution; the stone dissolution rate was not lower than in the group treated with ursodeoxycholic acid (UDCA). Stone size was significantly decreased after UDCA use if resolution did not occur. Conclusions Pediatric gallstones showed high resolution rate, and the clinical course was largely benign. CS use was the most common risk factor and did not predict a higher dissolution rate. Type IVa CC was also an important risk factor associated with a high recurrence rate. Conservative treatment and oral UDCA may be reasonable strategies in most patients, unless complications are present.

Background Tumour necrosis factor inhibitors (TNFis) improve joints outcomes and reduce cardiovascular (CV) risk in patients with rheumatoid arthritis (RA). However, 20%-45% of RA patients are TNFi poor responders and have a significantly higher risk of CV events. In these TNFi nonresponders, the use of second-line biologic agents to improve synovial outcomes is supported by clinical trials and real-world experience. However, it remains unknown what kind of immune-mediated agent has the best CV prevention effect in this high-risk population. Methods A nationwide RA cohort obtained from Taiwan’s National Health Insurance claims database was constructed. RA patients first treated with TNFis who then received either rituximab, tocilizumab, or abatacept were enrolled and followed for 2 years. Results A total of 89,973 RA patients were screened and 1,584 patients ultimately included. The incidences of major adverse cardiac events (MACE) at 2 years in the rituximab, tocilizumab, and abatacept groups were 7.17%, 2.75% and 2.38%, respectively. Multivariate adjusted Cox analysis showed that tocilizumab had significantly lower risk than rituximab in myocardial infarction (hazard ratio [HR] 0.12, 95% confidence interval [CI] 0.02-0.56; P = 0.008), and MACE (HR 0.41, 95% CI 0.23-0.72; P = 0.002). In addition, abatacept also had significant lower adjusted risk than rituximab in stroke (HR 0.18, 95% CI 0.05-0.64; P = 0.008), heart failure (HR 0.20, 95% CI 0.05-0.83; P = 0.027), and MACE (HR 0.25, 95% CI 0.11-0.55; P Conclusions TNFi-nonresponder patients with RA who received second-line tocilizumab or abatacept had more benefit on CV events prevention compared with those who received rituximab.

Background Gastrointestinal injury following blunt abdominal trauma is uncommon; a combined stomach and duodenal perforating injury is even more rare. Because these two organs are located in different spaces in the abdomen, such injuries are difficult to identify. Case presentation A young woman involved in a motor vehicle crash presented to our emergency department with concerns of severe peritonitis. Contrast-enhanced computed tomography of the abdomen revealed pneumoperitoneum and retroperitoneal hematoma in zone 1. An emergency laparotomy was performed, revealing a stomach-perforating injury, which was resolved with primary repair. No obvious injury was observed on retroperitoneal exploration. However, peritonitis presented again on the second postoperative day, and a second laparotomy was performed, revealing a duodenum-perforating injury in its third portion. We performed primary repair with multi-tube-ostomy. The patient recovered well without permanent tube placement or internal bypass. Conclusions Assessing associated injuries in blunt abdominal trauma is crucial because they may be fatal if timely intervention is not undertaken. These types of complicated injuries require a feasible surgical strategy formulated by experienced surgeons, which gives the patient a better chance of survival.

Background Aortic dissection (AD) is a life-threatening emergency. However, the heritability and association of family history with late outcomes are unclear. Objectives The purpose of this study was to evaluate the effect of family history of AD on the incidence and prognosis of AD and estimate the heritability and environmental contribution in AD in Taiwan. Methods Both cross-sectional and cohort studies were conducted using Taiwan National Health Insurance database. A registry parent–offspring relationship algorithm was used to reconstruct the genealogy of this population for heritability estimation. The cross-sectional study included 23,868 patients with a diagnosis of AD in 2015. The prevalence and adjusted relative risks (RRs) were evaluated, and the liability threshold model was used to examine the effects of heritability and environmental factors. Furthermore, a 1:10 propensity score–matched cohort comprising AD patients with or without a family history of AD was included to compare late outcomes in the cohort study. Results A family history of AD in first-degree relatives was associated with an RR of 6.82 (95% confidence interval [CI]: 5.12 to 9.07). The heritability of AD was estimated to be 57.0% for genetic factors, and 3.1% and 40.0% for shared and nonshared environmental factors, respectively. After excluding individuals with Marfan syndrome or bicuspid aortic valve, a family history of AD was associated with an RR of 6.56 (95% CI: 4.92 to 8.77) for AD. Furthermore, patients with AD and a family history of AD had a higher risk of later aortic surgery than those with AD without a family history (subdistribution hazard ratio: 1.40; 95% CI: 1.12 to 1.76). Conclusions A family history of AD was a strong risk factor for AD. Furthermore, patients with AD with a family history of AD had a higher risk of later aortic surgery than those with no family history of AD.

Given the speculation of the market economy causing an epidemic of depression, this study aimed to examine the influence of international trade on the prevalence of depressive disorders. We used panel data from 1993 to 2015 covering 170 countries (n = 3787) and applied fixed effects regression models. We modeled the prevalence of depressive disorders as a function of international trade, adjusting for economic development, economic growth, and population size. Regime types, media freedom, and capital–labor ratio were included as moderators. A 100% point increase in the value of international trade indicated a 0.09% point decrease in the prevalence of depressive disorders (− 0.09, confidence interval [CI] − 0.01 to − 0.18). However, this effect existed only for democratic countries (− 0.15, CI − 0.03 to − 0.28). The effect was more prevalent when the governments allowed the media more freedom (score of 100, − 0.31, CI − 0.17 to − 0.45) or when a country’s capital–labor ratio of endowments was high (50,000, − 0.22, CI − 0.08 to − 0.35). Trade brings about positive mental health outcomes in democracies, countries having free media, or capital-abundant economies.

Objectives Early mortality, defined as death within 120 days after initiated antitumor therapy, is an important issue especially for elder patients with B-cell lymphoma. This study aimed to evaluate the clinical value of comprehensive geriatric assessment (CGA) in early mortality prediction in elderly patients with B-cell lymphoma receiving immunochemotherapy. Methods Seventy-six consecutive patients with newly diagnosed B-cell lymphoma receiving immunochemotherapy from a medical center in Taiwan were prospectively enrolled. Patients were divided into fit (n = 49) and frail (n = 27) groups per pretreatment CGA for early mortality comparison. Results The early mortality rate in our patient cohort was 16% (n = 12): from 6% in patients with no CGA domain impairment to 43% in patients with ≥4 CGA domain impairment. The early mortality rate was 6% and 33% in fit and frail patients (odds ratio, 7.67; 95% CI, 1.86-31.6; P = .005), respectively. Frailty was the significant predictor for early mortality in univariate and multivariate analysis. Conclusion In this study, the number of geriatric domain impairment is positively associated with the early mortality risk in elderly patients with B-cell lymphoma. Therefore, CGA can help clinicians to identify the risk of early mortality in elderly patients and provide alternative treatment.

With the broad indications for dental implantation, complications rates have increased. Dental implant displacement into the maxillary sinus, although rare, can occur during the restoration of maxillary posterior teeth. We performed a 6-year retrospective review and found 3 cases with displaced implants in the maxillary sinus. Detailed information, including surgical indications and dental implant removal methods, is provided. Dental implants can be dislocated to the maxillary sinus perioperatively or postoperatively. Endoscopic sinus surgery can be performed to remove the implant and restore sinus patency. If the implant is displaced to deeper areas (commonly anterior and inferior) of the maxillary sinus, a prelacrimal recess approach can provide a panoramic view of the maxillary sinus and is a good alternative to the Caldwell-Luc operation in terms of mucosal preservation and postoperative complications.

Objective:This study examined the effect of daily life reading activity on the risk of cognitive decline and whether the effect differs regarding education levels.Design:A longitudinal study with 6-, 10-, and 14-year follow-up.Setting:Face-to-face interviews with structured questionnaires at home.Participants:A representative sample of 1,962 Taiwanese community-dwelling older persons aged 64 and above, followed up in four waves of surveys over 14 years.Measurements:Baseline reading frequencies were measured based on a scale of leisure activity. The Short Portable Mental Status Questionnaire was used to measure cognitive performance. We performed logistic regression to assess associations between baseline reading and later cognitive decline. Interaction terms between reading and education were to compare the reading effects on cognitive decline at different education levels.Results:After adjusting for covariates, those with higher reading frequencies (≥1 time a week) were less likely to have cognitive decline at 6-year (adjusted odds ratio [AOR]: 0.54; 95% confidence interval [CI]: 0.34–0.86), 10-year (AOR: 0.58, 95% CI: 0.37–0.92), and 14-year (AOR: 0.54, 95% CI: 0.34–0.86); in a 14-year follow-up, a reduced risk of cognitive decline was observed among older people with higher reading frequencies versus lower ones at all educational levels.Conclusions:Reading was protective of cognitive function in later life. Frequent reading activities were associated with a reduced risk of cognitive decline for older adults at all levels of education in the long term.

BackgroundStudies specifically examining the association between glycated hemoglobin A1c (HbA1c) levels and ischemic stroke/systemic thromboembolism (IS/SE) risk in atrial fibrillation (AF) patients are limited. Here, we investigated the association between HbA1c levels and the risk of IS/SE, as well as major bleeding, among AF patients with or without oral anticoagulants (OACs). We also compared the effectiveness and safety of warfarin and direct oral anticoagulants (DOACs) in different HbA1c categories.MethodsWe utilized medical data from a multi-center healthcare provider in Taiwan, which included 34,036 AF patients with serum HbA1c data available within 3 months after AF being diagnosed. Patients were divided into seven study groups according to their HbA1c levels: ResultsCompared with the patients with HbA1c level Pinteractions > 0.05).ConclusionFor AF patients, IS/SE risk significantly increased once HbA1c levels exceeded 6.5%, and OACs may attenuate these associations. Compared with warfarin, DOACs were more effective and safer across broad HbA1c categories. Therefore, in addition to prescribing DOACs when indicated, more aggressive glycemic control to achieve an HbA1c level

Objective Patients with hyperthyroidism were excluded from the randomized clinical trials of direct oral anticoagulants (DOACs) for stroke prevention in patients with nonvalvular atrial fibrillation (NVAF). Methods We performed a nationwide retrospective cohort study using data from the Taiwan National Health Insurance Research Database. We enrolled 3213 and 1181 NVAF patients with hyperthyroidism who were taking DOACs and warfarin, respectively, from June 1, 2012 to December 31, 2017. We also enrolled 53 591 and 16 564 NVAF patients without hyperthyroidism, taking DOACs and warfarin, respectively. We used propensity score stabilized weights (PSSWs) to balance covariates across the study groups. We also used 1:4 matching on both taking DOACs, with (n = 3213) and without hyperthyroidism (n = 12 852); and both taking warfarin, with (n = 1181) and without hyperthyroidism (n = 4724). Results After PSSW, DOAC had a comparable risk of ischemic stroke/systemic embolism (IS/SE) and a lower risk of major bleeding (hazard ratio [HR] 0.65; 95% confidential interval [CI], 0.44–0.96; P = 0.0295) than warfarin among patients with hyperthyroidism. There were comparable risks of IS/SE and major bleeding between those patients with and without hyperthyroidism. However, among patients taking warfarin, those with hyperthyroidism had a lower risk of IS/SE than those without hyperthyroidism (HR 0.61; 95% CI, 0.43–0.86; P = 0.0050). Conclusion Among NVAF Asian patients with concomitant hyperthyroidism, DOACs may be an effective and safer alternative to warfarin. Thromboprophylaxis with DOACs may be considered for such patients, and it is important to validate this finding in further prospective study.

A practical screening tool for early detection of unhealthy behaviors among adults to provide tailored care can have an important role in public health nursing.To develop a screening tool with valid psychometric properties for adult health behaviors (AHBs).A cross-sectional study was conducted between March 2018 and September 2019 in central-southern Taiwan. The AHBs development included qualitative and quantitative measurement of items based on literature reviews and expert opinion and exploration and confirmatory factor analysis.A total of 765 community adult participants: 377 women and 388 men, with a mean age of 39.3 (SD = 10.6), ranging from 20 to 64 years completed the AHBs screening tool. Analysis of the 23-items AHBs scale identified six dimensions - stress management, physical activity, health responsibility, life appreciation, healthy eating, and oral hygiene accounting for 67.3% of the variance. Total scale scores were significantly associated with a criterion variable of life satisfaction.The AHBs scale is a suitable screening tool that can be used to identify adults' unhealthy behaviors early, which is useful for public health nurses to conduct a regular assessment and initiate individualized health programs.

Current international normalized ratio (INR) guidelines are based on trials involving European and US populations. To our knowledge, no adequate study involving Asian patients has been conducted to date.To evaluate the association between INR and anticoagulation-related outcomes in an Asian population after mechanical aortic valve replacement (AVR) or mitral VR (MVR).This retrospective cohort study was conducted between 2001 and 2018, with follow-up until December 31, 2018, among patients who underwent AVR, MVR, or combined AVR-MVR at 3 medical centers and 4 regional hospitals and contributed electronic medical records to the Chang Gung Research Database. Exclusion criteria were missing demographic characteristics, younger than 20 years, fewer than 2 INR records, and having died during the hospitalization of the index surgery.Bleeding and thromboembolic complications were analyzed. The possibility of nonlinearity and cutoff potential for the INR were explored using a logistic regression model, which considered the INR a restricted cubic spline (RCS) variable.The study population consisted of 900 patients, with 525 (58.3%) men and 375 (41.7%) women and a mean (SD) age of 52.0 (12.5) years. Overall, 474 (52.7%) received AVR alone, 329 (36.6%) received MVR alone, and 97 (10.8%) received combined AVR-MVR. All patients had at least 2 INR examinations after discharge, providing 16 676 INR records for the AVR group and 18 207 for the MVR and combined AVR-MVR groups. In the AVR group, the RCS model showed that higher risks of composite thromboembolic events were associated with an INR of less than 2.0 or greater than 2.6 vs an INR of 2.0, and a higher risk of bleeding events was associated with an INR of less than 1.8 or greater than 2.4 vs an INR of 2.0. When treating the INR as a categorical variable, the risk of composite thromboembolic and composite bleeding events was significantly higher among patients with INRs less than 1.5 (adjusted odds ratio [aOR], 2.55; 95% CI, 1.37-4.73) and with INRs of 3.0 or greater (aOR, 3.48; 95% CI, 1.95-6.23) vs those with INRs between 2.0 and 2.5.In the MVR and combined AVR-MVR groups, higher risks of composite thromboembolic events were associated with an INR of less than 2.1 or greater than 2.7 vs an INR of 2.5, and a higher risk of bleeding events was associated with an INR of less than 2.1 or greater than 2.8 vs an INR of 2.5. When treating the INR as a categorical variable, the risk of a composite bleeding events was significantly higher among patients with INRs of 3.5 or greater (aOR, 2.25; 95% CI, 1.35-3.76) vs those with INRs between 2.5 and 3.0.Among Asian patients in this study, the incidence of thromboembolic events in the MVR group with INRs in the range of 2.0 to 2.5 was not significantly higher than that among those with INRs in the range of 2.5 to 3.0; in the AVR group, the incidence for those with INRs in 1.5 to 2.0 range was not significantly higher than for those with INRs in the range of 2.0 to 2.5.

Objective To evaluate the association between the use of antipsychotic drugs and cholinesterase inhibitors and the risk of falls and fractures in elderly patients with major neurocognitive disorders. Design Self-controlled case series. Setting Taiwan’s National Health Insurance Database. Participants 15 278 adults, aged ≥65, with newly prescribed antipsychotic drugs and cholinesterase inhibitors, who had an incident fall or fracture between 2006 and 2017. Prescription records of cholinesterase inhibitors confirmed the diagnosis of major neurocognitive disorders; all use of cholinesterase inhibitors was reviewed by experts. Main outcome measures Conditional Poisson regression was used to derive incidence rate ratios and 95% confidence intervals for evaluating the risk of falls and fractures for different treatment periods: use of cholinesterase inhibitors alone, antipsychotic drugs alone, and a combination of cholinesterase inhibitors and antipsychotic drugs, compared with the non-treatment period in the same individual. A 14 day pretreatment period was defined before starting the study drugs because of concerns about confounding by indication. Results The incidence of falls and fractures per 100 person years was 8.30 (95% confidence interval 8.14 to 8.46) for the non-treatment period, 52.35 (48.46 to 56.47) for the pretreatment period, and 10.55 (9.98 to 11.14), 10.34 (9.80 to 10.89), and 9.41 (8.98 to 9.86) for use of a combination of cholinesterase inhibitors and antipsychotic drugs, antipsychotic drugs alone, and cholinesterase inhibitors alone, respectively. Compared with the non-treatment period, the highest risk of falls and fractures was during the pretreatment period (adjusted incidence rate ratio 6.17, 95% confidence interval 5.69 to 6.69), followed by treatment with the combination of cholinesterase inhibitors and antipsychotic drugs (1.35, 1.26 to 1.45), antipsychotic drugs alone (1.33, 1.24 to 1.43), and cholinesterase inhibitors alone (1.17, 1.10 to 1.24). Conclusions The incidence of falls and fractures was high in the pretreatment period, suggesting that factors other than the study drugs, such as underlying diseases, should be taken into consideration when evaluating the association between the risk of falls and fractures and use of cholinesterase inhibitors and antipsychotic drugs. The treatment periods were also associated with a higher risk of falls and fractures compared with the non-treatment period, although the magnitude was much lower than during the pretreatment period. Strategies for prevention and close monitoring of the risk of falls are still necessary until patients regain a more stable physical and mental state.

Few prospective cohort trials have evaluated the difference in treatment-interval total body composition (TBC) changes assessed by dual-energy X-ray absorptiometry (DXA) between two patient subgroups with locally advanced head and neck squamous cell carcinoma (LAHNSCC) receiving concurrent chemoradiotherapy (CCRT): oral cavity cancer with adjuvant CCRT (OCC) and non-oral cavity with primary CCRT (NOCC). This study prospectively recruited patients with LAHNSCC. Clinicopathological variables, blood nutritional/inflammatory markers, CCRT-related factors, and TBC data assessed by DXA before and after treatment were collected. Multivariate linear regression analysis identified the factors associated with treatment-interval changes in body composition parameters, including lean body mass (LBM), total fat mass (TFM), and bone mineral content (BMC). A total of 127 patients (OCC (n = 69) and NOCC (n = 58)) were eligible. Body composition parameters were progressively lost during CCRT in both subgroups. Extremities lost more muscle mass than the trunk for LBM, whereas the trunk lost more fat mass than the extremities for TFM. BMC loss preferentially occurred in the trunk region. Different factors were independently correlated with the interval changes of each body composition parameter for both OCC and NOCC subgroups, particularly mean daily calorie intake for LBM and TFM loss, and total lymphocyte count for BMC loss. In conclusion, treatment-interval TBC changes and related contributing factors differ between the OCC and NOCC subgroups.

Globally, 32% to 70% patients with atrial fibrillation (AF) are prescribed oral anticoagulants (OACs) with warfarin for stroke prevention. However, patients with AF on OACs may experience intracranial hemorrhage (ICH), which presents a treatment dilemma. We therefore investigated whether resuming OACs in these patients is beneficial. Electronic medical records of patients with AF on OACs discharged with ICH between 2001 and 2013 were retrieved from the Taiwan National Health Insurance Research Database for analysis. We excluded patients who were 6 weeks after ICH diagnosis. The remaining patients were categorized into those who resumed OAC and those who discontinued OAC. Propensity score matching was performed between the 2 groups. Primary outcomes were mortality/ischemic stroke (IS)/systemic embolism (SE), IS/SE, and recurrent ICH at 6 months and 1 year. After the exclusion criteria were applied, 604 eligible patients (408 discontinued OAC and 196 resumed OAC within 6 weeks) were included in this study, and 186 patients in each group were 1:1 matched. Patients who resumed OAC had significantly lower mortality/IS/SE (hazard ratio [HR] = 0.39, 95% confidence interval [CI] = 0.20–0.76) and IS/SE (HR = 0.12, 95% CI = 0.03–0.53) at 6-month follow-up than patients who discontinued OAC. In addition, patients who resumed OAC had significantly lower mortality/IS/SE (HR = 0.56, 95% CI = 0.34–0.93) and IS/SE (HR = 0.26, 95% CI = 0.09–0.75) at 1-year follow-up. No difference in recurrent ICH was noted between the 2 groups. In conclusion, in patients with AF on OACs with ICH, resuming anticoagulant use was associated with significantly lower risks of composite outcomes of mortality/IS/SE and IS/SE than patients who discontinued OACs. No difference in recurrent ICH was observed between the 2 groups.

Introduction: Splenectomy is an important and potentially curative treatment for immune thrombocytopenia (ITP). Laparoscopic splenectomy (LS) has replaced open splenectomy (OS) as the standard approach. The prognostic role of platelet count and the clinical indication of preoperative platelet transfusion are not entirely clear. Methods: We designed a study to explore the prognostic impact of surgical methods, platelet count, and platelet transfusion in a large, single-institute, long-term cohort of ITP patients. Result: In 118 ITP patients, there was no difference between OS and LS in response and surgical complications. The overall response rate was 77% and the complete response (CR) rate was 70%. Patients with a CR had a trend towards a higher baseline platelet count. A stable platelet count 14–28 days after splenectomy was associated with a sustained long-term response. Patients requiring preoperative platelet transfusion had a lower preoperative platelet count and were more likely to need postoperative transfusion of red blood cells and platelets. They also had a lower postoperative platelet count than the nontransfusion group. Relapse-free survival did not differ. Conclusions: Baseline and postoperative platelet counts are apparently associated with the treatment response to splenectomy but the difference did not reach statistical significance. Preoperative platelet transfusion did not overcome the disadvantage of thrombocytopenia and was not recommended when other preparative measures are available.

Hyperuricemia has been associated with chronic kidney disease (CKD) progression. The antihyperuricemic febuxostat's potential renoprotective effect has been demonstrated in stage 1–3 CKD. Large‐scale studies comparing the renoprotective potential of febuxostat and allopurinol in advanced CKD are lacking. We exclusively selected 6,057 eligible patients with predialysis stage 5 CKD prescribed either febuxostat or allopurinol using the National Health Insurance Research Database in Taiwan during 2012–2015. There were 69.57% of allopurinol users and 42.01% febuxostat users who required long‐term dialysis (P

This study aimed to evaluate prognostic impacts of the number of lymph nodes (LNs) examined and LN ratio on cancer-specific mortality after surgery in patients with right-sided colon cancer (RCC) or left-sided colon cancer (LCC) using the Surveillance, Epidemiology, and End Results database. Number of LNs examined and LN ratio were treated as categorical and/or continuous. Competing risks proportional hazards regressions adjusted by propensity score were performed. All included patients had stage I, II, or III disease, and 45.1% of them had RCC. RCC and LCC patients with high level of LNs examined had better prognosis after segmental resection or hemicolectomy. RCC and LCC patients with higher LN ratio had worse prognosis regardless of surgery. Survival benefit of having high level of LNs examined was observed in RCC patients with stage I, II, or III disease, but only in LCC patients with stage II disease. Both higher LN ratio and high level of LN were negative prognostic factors for cancer-specific mortality in stage III patients regardless of tumor sidedness. In conclusion, RCC patients in various conditions had worse or comparable prognosis compared to their LCC counterparts, which reflected the severity of LN metastasis.

Although cases of empty nose syndrome (ENS) are not very common, the suffering that ENS causes patient is immense and could be very difficult to imagine. Nasal nitric oxide (nNO) is an airway disease biomarker, and its levels increase after endoscopic sinus surgery. The trend of nNO levels in ENS before and after surgical treatment remains unknown. This study aimed to evaluate the role of nNO in ENS.Patients with ENS who received surgical implantation and with chronic hypertrophic rhinitis (CHR) who underwent turbinoplasty and completed at least 1 year of follow-up were prospectively enrolled. nNO measurements and subjective assessments [SinoNasal Outcome Test (SNOT)-22, Beck Depression Inventory (BDI)-II, and Beck Anxiety Inventory (BAI)] were performed preoperatively and at 3, 6, and 12 months postoperatively.We enrolled 19 ENS and 12 CHR patients. nNO levels were significantly lower in the ENS than in the CHR patients before surgical treatment (p 0.001). nNO levels in the ENS patients significantly increased 3 months after implantation and remained plateaued (p = 0.015). BDI-II and BAI scores significantly improved after surgical treatment for the ENS patients but not for the CHR patients; changes in nNO levels correlated well with improvements in BDI-II and BAI scores (p = 0.025 and 0.035, respectively).nNO significantly increased at third month after surgical treatment and remained plateaued in ENS patients. This increase correlated with improvements in BDI-II and BAI scores. Therefore, nNO may be important in assessing the psychiatric status of empty nose syndrome.

Background: Severe headaches, projectile vomiting, focal neurological deficits and early onset seizure are regarded as early warning symptoms of subarachnoid hemorrhage (SAH). Earlier diagnosis based on such warning symptoms theoretically would improve the clinical prognosis. However, it is still not clear whether the prognosis is correlated with early warning symptoms. Here, we reviewed warning symptoms and other predictive factors in the emergency room (ER) setting and examined their correlations with mortality. Methods: Ninety saccular aneurysmal SAH cases were reviewed in a single medical center between January 2011 and December 2013. We examined differences in mortality rate related to warning symptoms, SAH scales, onset-to-ER time, hydrocephalus, and aneurysm size, location, and complexity. Logistic regression analyses were performed to determine the correlations of warning symptoms and other predictive factors with mortality. Receiver operating characteristic (ROC) curve analysis was used to calculate the area the under curve (AUC) of SAH mortality prediction tools. Results: Warning headache, projectile vomiting, the Hunt and Hess scale, Fisher scale, World Federation of Neurological Surgeons (WFNS) grading scale, and modified WFNS (m-WFNS) scale, body mass index, aneurysm complexity and hydrocephalus were significantly different between the survivors and the decedents. The warning headache and WFNS grade were strongly correlated with mortality. The rate of prognostic prediction improved from 90.4% to 94.6% when warning headache was additionally evaluated. Conclusions: With growing healthcare costs and recognition of the value of palliative care, early identification via warning headache and a detailed clinical history review is necessary for cases of aSAH. Keywords: Warning headache, SAH, WFNS, Survival rate

Background We previously developed a robust prognostic model (GS model) to predict the survival outcome of patients with advanced pancreatic cancer (APC) receiving palliative chemotherapy with gemcitabine plus S‐1 (GS). This study aimed to validate the application of the GS model in APC patients receiving chemotherapy other than the GS regimen. Patients and methods We retrospectively analyzed 727 APC patients who received first‐line palliative chemotherapy other than the GS regimen between 2010 and 2016 at four institutions in Taiwan. The patients were categorized into three prognostic groups based on the GS model for comparisons of survival outcome, best tumor response, and in‐group survival differences with monotherapy or combination therapy. Results The median survival times for the good, intermediate, and poor prognostic groups were 13.4, 8.4, and 4.6 months, respectively. The hazard ratios for the comparisons of intermediate and poor to good prognostic groups were 1.51 (95% confidence interval [CI]), 1.22‐1.88, P, This study provided validation of the previously developed gemcitabine + S‐1 model in predicting the survival outcome of advanced pancreatic cancer patients receiving first‐line palliative chemotherapy.

Studies on the cholesterol‐serotonin hypothesis and its link to mood disorders are scarce. In addition, little is known about the association between cholesterol and the effects of tryptophan depletion (TD). The aim of the present study was to investigate the association between plasma cholesterol and changes in heart rate variability (HRV), an important marker of depression and anxiety, after TD. The plasma cholesterol levels of 28 healthy participants were noted, and their HRVs were measured by spectrum analysis. TD was carried out on testing day, and participants provided blood samples just before and 5 hours for tryptophan level after TD. HRV was measured again after TD. An association was found between plasma cholesterol levels and the change in HRV. Decreased high frequency HRV was marginally associated with lower levels of high‐density lipoprotein cholesterol, while increased low frequency HRV was significantly associated with lower levels of total and low‐density lipoprotein cholesterol. Our findings indicate that low cholesterol levels may play parts of role in the mechanism of the deactivation of parasympathetic, and activation of sympathetic, functions induced by altered serotonergic function.

Background The cephalomedullary nail is the most common device used to treat unstable intertrochanteric fractures (ITFs) (AO/OTA 31-A2 and A3) in the geriatric population. However, there is lack of radiological parameter to evaluate the entry point; hence, this study reports a new radiological parameter to evaluate the entry point of the nail. Besides, other risk factors were also examined. Methods A retrospective study on the geriatric population with unstable ITFs was conducted from July 2011 to December 2014. A total of 136 patients were enrolled in this study; they received treatment with Gamma-3 nails (Stryker, Mahwah, NJ, USA) and were followed for at least 1 year. Demographic data, radiological parameters, and side-difference of the distance from the piriformis fossa to the greater trochanteric tubercle in the anteroposterior view (dPG) were compared between the union and failure groups. Student's t test, χ test, and multiple logistic regression were used in the statistical analyses. Results The overall failure rate was 13.23% (18 patients). Sex, tip-apex distance (TAD), and dPG were significantly different between the failure and union groups in multivariate analyses. Using a dPG > 6 mm as a reference, patients with a dPG > 6 mm had an odds ratio of 7.64 for failure relative to a dPG Conclusion This study provides additional evidence demonstrating that sex and TAD have significant effects on the outcomes of unstable ITFs after nailing. Moreover, the newly reported radiological parameter, dPG, can be used to predict the failure of ITFs treated using cephalomedullary nails.

Purpose:The aim of this study was to evaluate outcomes of internal fixation for displaced femoral neck fracture (FNF) between 50 and 60 years old. The patient and surgical factors for the failure were identified.Methods:We retrospectively reviewed the records of 102 displaced FNF patients between 50 and 60 years old (mean age 54.9 years) who had undergone internal fixation between 2005 and 2016. The minimum follow-up was 12 months. Primary end points included loss of reduction, non-union, and osteonecrosis of the femoral head (ONFH). Preoperative Pauwel’s angle, fixation timing and methods, reduction quality, removal of implant and medical comorbidities were analysed.Results:The overall failure rate was 44.1%. In multivariate logistic regression analysis, poor reduction quality (adjusted odds ratio [aOR] 4.38; 95% confidence interval [CI], 1.54–12.46) and internal fixation delayed more than 6 hours (aOR 3.24; 95% CI, 1.08–9.69) were risk factors for all causes of failure. In a stratified analysis, poor reduction quality (aOR 3.81; 95% CI, 1.11–13.04) and a history of alcohol dependency (aOR 4.91; 95% CI, 1.09–22.13) were risk factors for loss of reduction. Internal fixation delayed >6 hours (aOR 3.67; 95% CI, 1.05–12.77) and removal of implant (aOR 3.32; 95% CI, 1.02–10.77) were risk factors for ONFH.Conclusions:The outcome of internal fixation of displaced FNF in patients between 50 and 60 years old is suboptimal. The patient selection is important. Non-alcohol dependency lowered early failure. Implant retention reduced ONFH. Surgery within 6 hours and good quality of reduction yield better results.

Objective Studies have rarely explored the efficacy of S‐1 in treating advanced pancreatic cancer outside Japan. This study compared the survival outcomes of patients with advanced pancreatic cancer treated with S‐1 with the survival outcomes of those without S‐1 treatment before and after S‐1 reimbursement was introduced in Taiwan in June of 2014. Method We retrospectively analyzed 838 patients with locally advanced or metastatic pancreatic cancer who underwent palliative chemotherapy from 2010 to 2016 at 4 institutes in Taiwan. For survival analysis, patients were categorized into two groups according to whether they received S‐1 treatment as palliative chemotherapy after diagnosis: (a) S‐1‐treated (n = 335) and (b) non‐S‐1‐treated (n = 503) groups. Results The median overall survival was longer in the S‐1‐treated group than in the non‐S‐1‐treated group (10.7 vs 6.0 mo, P

Aims and objectives To examine the gender-specific lifestyles of adults with metabolic syndrome in the Taiwanese community. Background Many studies show different prevalence of metabolic syndrome in males and females; however, few studies have investigated gender-specific lifestyle risk factors, which are important for effectively reducing prevalence. Design A cross-sectional study design was used. Methods Between 2012 and 2015, a total of 1,066 individuals were recruited in northern Taiwan. Data were collected by questionnaires and analysed by descriptive statistics, chi-square tests and logistic regression. This study followed the STROBE guidelines. Results The prevalence of metabolic syndrome was 40.8% in men and 36.0% in women. Women had healthier dietary habits, a higher rate of moderate-vigorous physical activity, and a lower rate of smoking and obesity than men. Men, who were overweight or obese, lacked vigorous physical activity, often consumed excess amounts of salt and fat, and seldom consumed appropriate amounts of protein tended to have metabolic syndrome. Women with an unhealthy metabolism tended to be overweight or obese and seldom consumed dairy products. Conclusions Men, who had normal body weight, performed vigorous physical activity, seldom consumed excess amounts of salt and fat, and often consumed appropriate amounts of protein tended not to have metabolic syndrome. Women with a healthy metabolism were of normal body weight and often consumed dairy products. There exist gender differences in health habits with metabolic syndrome. Relevance to clinical practice Although the associated risk factors differed between men and women, controlling body weight and maintaining a healthy lifestyle may reduce the risk of metabolic syndrome.

Previous studies have indicated traumatic brain injury (TBI) as a risk factor for stroke and myocardial injury. Whether TBI increases new onset of major adverse cardiovascular and cerebrovascular events (MACCE) is not well established.Patients with a diagnosis of TBI from 2000 to 2012 were 1:2 age-, sex-, and age-adjusted comorbidities matched with normal population cohorts. The MACCE, which included coronary artery disease, heart failure and arrhythmia, ischemic and hemorrhagic stroke, and death, was defined as one inpatient admission with MACCE diagnosis. The maximum follow-up duration to MACCE after the initial TBI diagnosis was 5 years. The baseline comorbidities before TBI, including hypertension, diabetes mellitus, renal disease, and liver disease, also were considered to estimate the risk of MACCE.In total, 16,211 patients with TBI and 32,422 people from the control group were enrolled in the current study. Our results showed that patients with TBI had a 2.77-fold risk of MACCE, 1.72-fold risk of cardiovascular disease, 2.10-fold risk of ischemic stroke, 6.02-fold risk of hemorrhagic stroke, and 3.13-fold risk of mortality compared with the control group (all P0.0001) after adjusting the confounding factors. In addition, the trend of cumulated incidence risk among MACCE, cardiovascular disease, ischemic and hemorrhagic stroke, and mortality presented the greatest incidence within the first year after diagnosis and persisted during the 5 years of follow-up.Our results showed that patients with TBI have a significantly greater risk of MACCE than the control group. We hope this information will remind critical-care physicians and neurosurgeons to keep in mind the long-term effects of TBI on MACCE.

Background The treatment effects on hospitalization for heart failure (hHF) from sodium-glucose cotransporter 2 (SGLT2) inhibitors may vary among type 2 diabetes (T2D) patients depending on whether or not they have established atherosclerotic cardiovascular diseases (ASCVD). We aimed to examine differences in hHF outcomes after dapagliflozin or empagliflozin use between T2D patients with and without a history of established ASCVD. Methods We conducted a retrospective multi-institutional cohort study in Taiwan. We included T2D patients newly receiving dapagliflozin or empagliflozin during 2016–2019, and followed them up until December 31, 2020. We implemented 1:1 propensity score matching to create homogenous groups for comparisons. We generated Cox proportional hazard models to compare the risk of hHF between dapagliflozin and empagliflozin (reference group). We included interaction terms of SGLT2 inhibitor and ASCVD history in the regression models to examine effect modification by ASCVD. Results We included a total cohort of 9,586 dapagliflozin new users and 9,586 matched empagliflozin new users. The overall hHF risks were similar for dapagliflozin and empagliflozin (HR: 0.90, 95% CI 0.74–1.09). However, differential hHF risks between dapagliflozin and empagliflozin were observed only in the subgroup without ASCVD (HR: 0.67, 95% CI 0.49–0.90), while not in the subgroup with ASCVD (HR: 1.12, 95% 0.87–1.45), and the p-value for examining interaction was 0.0097. Conclusion In this study, history of established ASCVD was associated with different hHF risks among SGLT2 inhibitors. For T2D patients without ASCVD, dapagliflozin may offer a more favorable hHF reduction effect, compared to empagliflozin, in clinical practice. Future prospective studies should be conducted to validate our findings.

Fat embolism syndrome (FES) is a complication of long bone fractures that often occurs within 72 hours of injury. Early-onset isolated cerebral fat embolism is catastrophic and rarely reported. We herein present a rare case of delayed-onset isolated cerebral FES that developed 10 days after definite fixation of a left tibial plateau fracture. A 70-year-old woman was injured in a traffic accident and diagnosed with a left tibial plateau fracture. However, she developed sudden loss of consciousness (E4V1M1) and quadriplegia 10 days after fracture fixation. Her vital signs showed no respiratory distress. Diagnosis of isolated cerebral FES was made based on magnetic resonance imaging of the brain, the findings of which were compatible with the clinical neurological findings. After supportive care and rehabilitation, her consciousness became clear on the second day of admission, and her consciousness changed to E4V5M6. She gradually regained strength in her right limbs but had residual left limb paraplegia. Isolated cerebral FES should always be considered for patients who develop a change in consciousness, even beyond 72 hours after injury. Imaging may not initially show definitive abnormalities. Repeated magnetic resonance imaging should be considered if the initial clinical presentation does not fully meet Gurd’s criteria.

Fate determination and maintenance of fetal testes in most mammals occur cell autonomously as a result of the action of key transcription factors in Sertoli cells. However, the cases of freemartin, where an XX twin develops testis structures under the influence of an XY twin, imply that hormonal factor(s) from the XY embryo contribute to sex reversal of the XX twin. Here we show that in mouse XY embryos, Sertoli cell-derived anti-Mullerian hormone (AMH) and activin B together maintain Sertoli cell identity. Sertoli cells in the gonadal poles of XY embryos lacking both AMH and activin B transdifferentiate into their female counterpart granulosa cells, leading to ovotestis formation. The ovotestes remain to adulthood and produce both sperm and oocytes, although there are few of the former and the latter fail to mature. Finally, the ability of XY mice to masculinize ovaries is lost in the absence of these two factors. These results provide insight into fate maintenance of fetal testes through the action of putative freemartin factors.

Reliable protein markers for pre-diabetes in humans are not clinically available. In order to identify novel and reliable protein markers for pre-diabetes in humans, healthy volunteers and patients diagnosed with pre-diabetes and stroke were recruited for blood collection. Blood samples were collected from healthy and pre-diabetic subjects 12 h after fasting. BMI was calculated from body weight and height. Fasting blood glucose (FBG), glycated hemoglobin (HbA1C), triglyceride (TG), total cholesterol, high-density lipoprotein, low-density lipoprotein (LDL), insulin and albumin were assayed by automated clinical laboratory methods. We used a quantitative proteomics approach to identify 1074 proteins from the sera of pre-diabetic and healthy subjects. Among them, 500 proteins were then selected using Mascot analysis scores. Further, 70 out of 500 proteins were selected via volcano plot analysis according to their statistical significance and average relative protein ratio. Eventually, 7 serum proteins were singled out as candidate markers for pre-diabetes due to their diabetic relevance and statistical significance. Immunoblotting data demonstrated that laminin subunit alpha 2 (LAMA2), mixed-lineage leukemia 4 (MLL4), and plexin domain containing 2 (PLXDC2) were expressed in pre-diabetic patients but not healthy volunteers. Receiver operating characteristic curve analysis indicated that the combination of the three proteins has greater diagnostic efficacy than any individual protein. Thus, LAMA2, MLL4 and PLXDC2 are novel and reliable serum protein markers for pre-diabetic diagnosis in humans.

Background Dialysis‐requiring acute kidney injury (D‐AKI) is a major complication of cardiovascular surgery that results in worse prognosis. However, the incidence and impacts of D‐AKI in different types of cardiac surgeries have not been fully investigated. Methods and Results Patients admitted for cardiovascular surgery between July 1, 2004, and December 31, 2013, were identified from the National Health Insurance Research Database of Taiwan. The patients were grouped into D‐AKI (n=3089) and non–D‐AKI (n=42 151) groups. The outcome was all‐cause mortality and major adverse kidney event. The long‐term outcomes were worse in the D‐AKI group than the non–D‐AKI group (hazard ratio [HR], 3.89; 95% CI, 3.79–3.99 for major adverse kidney event; HR, 2.89; 95% CI, 2.81–2.98 for all‐cause mortality). Patients who underwent aortic surgery had higher risk for D‐AKI than other types of surgeries, but they were also more likely to recover. The long‐term dialysis rate for the patients who recovered from D‐AKI was also lowest in those who underwent aortic surgery. Among all types of cardiac surgeries with D‐AKI, patients who had heart valve surgery exhibited the greatest risks of all‐cause mortality (HR, 6.04; 95% CI, 5.78–6.32). Conclusions Compared with other heart surgeries, aortic surgery resulted in a higher incidence of D‐AKI but better renal recovery, better short‐term outcome, and lower incidences of long‐term dialysis.

Introduction The Clinical Dementia Rating (CDR) is widely used in Alzheimer's disease research studies and has well established reliability and validity. To facilitate the development of an online, electronic CDR (eCDR) for more efficient clinical applications, this study aims to produce a shortened version of the CDR, and to develop the statistical model for automatic scoring. Methods Item response theory (IRT) was used for item evaluation and model development. An automatic scoring algorithm was validated using existing CDR global and domain box scores as the reference standard. Results Most CDR items discriminate well at mild and very mild levels of cognitive impairment. The bi-factor IRT model fits best and the shortened CDR still demonstrates very high classification accuracy (81%∼92%). Discussion The shortened version of the CDR and the automatic scoring algorithm has established a good foundation for developing an eCDR and will ultimately improve the efficiency of cognitive assessment.

Background: Alzheimer’s disease (AD) is a complex and severe neurodegenerative disease that still lacks effective methods of diagnosis. The current diagnostic methods of AD rely on cognitive tests, imaging techniques and cerebrospinal fluid (CSF) levels of amyloid-β1-42(Aβ42), total tau protein and hyperphosphorylated tau (p-tau). However, the available methods are expensive and relatively invasive. Artificial intelligence techniques like machine learning tools have being increasingly used in precision diagnosis. Methods: We conducted a meta-analysis to investigate the machine learning and novel biomarkers for the diagnosis of AD. Methods: We searched PubMed, the Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews for reviews and trials that investigated the machine learning and novel biomarkers in diagnosis of AD. Results: In additional to Aβ and tau-related biomarkers, biomarkers according to other mechanisms of AD pathology have been investigated. Neuronal injury biomarker includes neurofiliament light (NFL). Biomarkers about synaptic dysfunction and/or loss includes neurogranin, BACE1, synaptotagmin, SNAP-25, GAP-43, synaptophysin. Biomarkers about neuroinflammation includes sTREM2, and YKL-40. Besides, d-glutamate is one of coagonists at the NMDARs. Several machine learning algorithms including support vector machine, logistic regression, random forest, and naïve Bayes) to build an optimal predictive model to distinguish patients with AD from healthy controls. Conclusions: Our results revealed machine learning with novel biomarkers and multiple variables may increase the sensitivity and specificity in diagnosis of AD. Rapid and cost-effective HPLC for biomarkers and machine learning algorithms may assist physicians in diagnosing AD in outpatient clinics.

Background To compare the value of interim 18F-FLT-PET and 18F-FDG-PET for predicting treatment outcomes in patients with metastatic breast cancer after salvage therapy. Methods Patients with metastatic breast cancer received PET/CT using 18F-FLT and 18F-FDG at baseline, after the 1st and 2nd cycle of systemic chemotherapy. The clinical response was classified according to Response Evaluation Criteria in Solid Tumors 1.1 based on contrast-enhanced CT after 3 months of systemic chemotherapy. The metabolic response on PET was assessed according to European Organization for Research and Treatment of Cancer criteria or PET Response Criteria in Solid Tumors (PERCIST) and was correlated to the clinical response, overall survival (OS), and progression-free survival (PFS). Results Twenty-five patients entered final analysis. On 18F-FDG-PET, clinical responders after 2 chemotherapy cycles (post-2c) had a significantly greater reduction of maximal standardized uptake value (SUV) and the peak SUV corrected for lean body mass (SULpeak) of the tumor than non-responders (P = 0.030 and 0.003). Metabolic response determined by PERCIST on post-2c 18F-FDG-PET showed a high area under the receiver operating characteristics curve of 0.801 in predicting clinical response (P = 0.011). Patients who were metabolic responders by PERCIST on post-2c 18F-FDG-PET had a significantly longer PFS (53.8% vs. 16.7%, P = 0.014) and OS (100% vs. 47.6%, P = 0.046) than non-responders. Survival differences between responders and non-responders in the interim 18F-FLT-PET were not significant. Conclusions 18F-FLT-PET failed to show an advantage over 18F-FDG-PET in predicting the treatment response and survival in patients with metastatic breast cancer. Assessment of treatment outcome by interim 18F-FDG-PET may aid treatment. Trial registration The study was retrospectively registered on 02/06/2020 on Clinicaltrials.gov (identifier NCT04411966).

This cohort study compares the risks of venous thromboembolism (VTE) recurrence in patients receiving non–vitamin K antagonist oral anticoagulants (NOACs) vs low-molecular-weight heparin in Asian individuals with cancer., Key Points Question Are there differences in risks of venous thromboembolism (VTE) recurrence or of bleeding events associated with taking a non–vitamin K antagonist oral anticoagulant (NOAC) compared with receiving a low-molecular-weight heparin (LMWH) among Asian patients with cancer-associated VTE? Findings In this cohort study of 1109 patients with cancer-associated VTE, use of a NOAC was not associated with increased risk of recurrent VTE or major bleeding but was associated with lower risk of gastrointestinal bleeding compared with use of the LMWH enoxaparin. Meaning These findings suggest that in real-world practice, among Asian individuals with cancer-associated VTE, use of a NOAC had similar risk for recurrent VTE or major bleeding compared with use of LMWH., Importance It is unclear whether the clinical benefits associated with non–vitamin K antagonist oral anticoagulants (NOACs) are similar to those associated with low-molecular-weight heparins (LMWHs) in Asian individuals with cancer and acute venous thromboembolism (VTE). Objective To compare the risk of recurrent thromboembolic events and bleeding associated with use of a NOAC vs use of the LMWH enoxaparin in Asian individuals with cancer-associated VTE. Design, Setting, and Participants This cohort study was conducted using data from the Chang Gung Research Database, a multi-institutional electronic medical records database in Taiwan. A cohort of 1109 patients with cancer-associated VTE were identified between January 1, 2012, and January 31, 2019. Data were analyzed from March 2019 through December 2020. Exposures Receiving a NOAC (including rivaroxaban, apixaban, edoxaban, or dabigatran) or the LMWH enoxaparin. Main Outcomes and Measures The primary outcomes were composite recurrent VTE or major bleeding. Stabilized inverse probability of treatment weighting was used to balance baseline covariates. We compared risks of recurrent VTE or major bleeding between groups using Cox proportional hazards models. In addition, we conducted an analysis using a Fine and Gray subdistribution hazard model that considered death as a competing risk. Results Among 1109 patients with cancer and newly diagnosed VTE, 578 (52.1%) were women and the mean (SD) age at index date was 66.0 (13.0) years; 529 patients (47.7%) received NOACs and 580 patients (52.3%) received the LMWH enoxaparin. Composite recurrent VTE or major bleeding occurred in 75 patients (14.1%) in the NOAC group and 101 patients (17.4%) in the enoxaparin group (weighted hazard ratio [HR], 0.77; 95% CI, 0.56-1.07; P = .11). The groups had similar risk of VTE recurrence (HR, 0.62; 95% CI, 0.39-1.01; P = .05) and major bleeding (HR, 0.80; 95% CI, 0.52-1.24; P = .32) at 12 months of follow-up. However, taking a NOAC was associated with a significantly lower risk of gastrointestinal bleeding compared with receiving enoxaparin (10 patients [1.9%] vs 41 patients [7.1%]; HR, 0.29; 95% CI, 0.15-0.59; P

Adjunctive psychosocial interventions are part of the preferred method to treat bipolar disorder (BD). This study aimed to conduct a randomized control and protocol-guided trial, in order to evaluate the feasibility and effectiveness of adjunctive group-based treatments for Chinese outpatients with BD. A single-blind trial in which 68 outpatients with BD were randomly assigned to either treatment as usual (TAU) or to an experimental group with 12 additional weekly sessions and 3 monthly booster sessions. Participants were assessed at baseline for mood condition, suicidal ideation, medication adherence, and quality of life (QoL), with follow-up assessments every 3 months over a 1-year period. The overall retention rate of this study was 89.7%. The results showed significant differences between groups for the variables evaluated, which included achieving euthymia, decrease of depression symptoms, and improvement of QoL. No improvements in medication adherence, reduction in manic symptoms, or suicidal ideation was observed. The results of this study support the transcultural validity and efficacy of group-based psychosocial intervention as anadjunct to TAU among Chinese outpatients with BD to promote improvements during the course of the illness including achieving euthymia, reducing depressive symptoms, and improving QoL.

Background To identify predictors of carotid artery stenosis (CAS) progression in head and neck cancer (HNC) patients after radiation therapy (RT). Methods We included 217 stroke-naïve HNC patients with mild carotid artery stenosis after RT in our hospital. These patients underwent annual carotid duplex ultrasound (CDU) studies to monitor CAS progression. CAS progression was defined as the presence of ≥50% stenosis of the internal/common carotid artery on follow-up CDU. We recorded total plaque score (TPS) and determined the cut-off TPS to predict CAS progression. We categorized patients into high (HP) and low plaque (LP) score groups based on their TPS at enrolment. We analyzed the cumulative events of CAS progression in the two groups. Results The TPS of the CDU study at enrolment was a significant predictor for CAS progression (adjusted odds ratio [aOR] = 1.69, p = 0.002). The cut-off TPS was 7 (area under the curve: 0.800), and a TPS ≥ 7 strongly predicted upcoming CAS progression (aOR = 41.106, p = 0.002). The HP group had a higher risk of CAS progression during follow-up (adjusted hazard ratio = 6.15; 95% confident interval: 2.29–16.53) in multivariable Cox analysis, and also a higher trend of upcoming ischemic stroke (HP vs. LP: 8.3% vs. 2.2%, p = 0.09). Conclusions HNC patients with a TPS ≥ 7 in any CDU study after RT are susceptible to CAS progression and should receive close monitoring within the following 2 years.
