Risk factors and metabolic abnormality of patients with non-alcoholic fatty liver disease: Either non-obese or obese Chinese population

Background: Non-alcoholic fatty liver disease(NAFLD) occurs not only in obese individuals but also in non-obese ones. The aim of this study was to focus on the association between NAFLD and metabolic events in a non-obese or obese Chinese population.Methods: Data collected from subjects registered at Taichung Veterans General Hospital from January to December 2009 were analyzed. The exclusion criteria were alcoholics, chronic hepatitis B or C. Patients included in analyses were assigned to four groups according to sonography of their liver(normal or NAFLD), and body mass index(BMI) levels(non-obese if BMI 25 kg/m~2 or obese if BMI ≥ 25 kg/m~2).Results: There were 745, 208, 770 and 285 patients enrolled in four groups labeled non-obese normal liver(group A), non-obese NAFLD(group B), obese normal liver(group C) and obese NAFLD(group D),respectively. The highest ratio of metabolic syndrome existed in the group B(26.9%), followed by group A(11.7%), group D(10.9%) and finally the group C(5.2%). The positive association with NAFLD in non-obese individuals was significant in triglyceride(OR = 1.01; 95% CI: 1.01–1.02) and glucose(OR = 1.02; 95% CI:1.01–1.03), while the positive association with NAFLD in obese subjects was only significant in triglyceride(OR = 1.01; 95% CI: 1.01–1.02). The positive association was most significant in all cases(adjusted OR = 2.41; 95% CI: 1.78–3.24), especially in non-obese individuals(OR = 2.81; 95% CI: 1.92–4.12).Conclusions: Non-obese NAFLD subjects displayed a higher proportion of metabolic abnormality. Hyperlipidemia and hyperglycemia had the most positive strength association with NAFLD.     

The clinicopathological and prognostic significance of PD-L1 expression in pancreatic cancer: A meta-analysis

Background: Immunotherapy has shown promise against solid tumors. However, the clinical significance of programmed cell death 1(PD-1) and programmed cell death ligand 1(PD-L1) in pancreatic ductal adenocarcinoma(PDAC) remains unclear. This meta-analysis aimed to analyze the prognostic effect of PD-L1 in PDAC.Data sources: Electronic search of the Pub Med, Cochrane Library and Web of Science was performed until December 2016. Through database searches, we identified articles describing the relationship between PD-L1 status and PDAC patient prognosis. Meta-analysis was performed to investigate the relationship between PD-1 and overall survival(OS).Results: Nine studies with 989 PDAC patients were included for PD-L1 expression analysis. And 5 studies with 688 PDAC patients were included in the prognostic analysis. The PD-L1 positive rate measured by immunohistochemistry(IHC) was higher than that measured by polymerase chain reaction(PCR)(P 0.001). PDAC patients with high expression levels of PD-L1 had significantly reduced OS(HR = 2.34;95% CI: 1.78–3.08). Subgroup analysis showed that the prognostic effect of PD-L1 levels was similar between the IHC and PCR methods. The PD-L1 positive rate was associated with PDAC T stages; the PD-L1 positive rate in the T3–4 group was higher than that in the T1-2 group(OR = 0.37; P = 0.001).Conclusions: High PD-L1 expression levels predicted a poor prognosis in PDAC patients. Thus, PD-L1 status helps determine treatment in PDAC patients.     

Predictors of 30-day readmission following pancreatic surgery: A retrospective review

Background: Pancreatectomies have been identified as procedures with an increased risk of readmission.In surgical patients, readmissions within 30 days of discharge are usually procedure-related. We sought to determine predictors of 30-day readmission following pancreatic resections in a large healthcare system.Methods: We retrospectively collected information from the records of 383 patients who underwent pancreatic resections from 2004–2013. To find the predictors of readmission in the 30 days after discharge,we performed a univariate screen of possible variables using the Fisher's exact test for categorical variables and the Mann–Whitney U test for continuous variables. Multivariate analysis was used to determine the independent factors.Results: Fifty-eight(15.1%) patients were readmitted within 30 days of discharge. Of the patients readmitted, the most common diagnoses at readmission were sepsis(17.2%), and dehydration(8.6%). Multivariate logistic regression found that the development of intra-abdominal fluid collections(OR = 5.32, P 0.0001),new thromboembolic events(OR = 4.08, P = 0.016), and pre-operative BMI(OR = 1.06, P = 0.040) were independent risk factors of readmission within 30 days of discharge.Conclusion: Our data demonstrate that factors predictive of 30-day readmission are a combination of patient characteristics and the development of post-operative complications. Targeted interventions may be used to reduce the risk of readmission.     

Diagnostic yield of EUS-FNA of small(≤15 mm) solid pancreatic lesions using a 25-gauge needle

Background: Early detection of small solid pancreatic lesions is increasingly common. To date, few and contradictory data have been published about the relationship between lesion size and endoscopic ultrasound-guided fine needle aspiration(EUS-FNA) diagnostic yield. The aim of this study was to assess the relation between the size of solid pancreatic lesions and the diagnostic yield of EUS-FNA using a 25-gauge needle in a center without available rapid on-site evaluation.Methods: In the retrospective cohort study, we selected patients who underwent EUS-FNA for solid pancreatic lesions with a 25-gauge needle from October 2014 to October 2015. Patients were divided into three groups(≤15 mm, 16–25 mm and 25 mm), and the outcomes were compared.Results: We analyzed 163 patients. Overall adequacy, sensitivity, specificity and accuracy were 85.2%,81.8%, 93.7%, and 80.4%, respectively. When stratified by size, the sensitivity and accuracy correlated with size(P = 0.016 and P = 0.042, respectively). Multivariate analysis showed that lesion size was the only independent factor(P = 0.019, OR = 4.76) affecting accuracy. The role of size as an independent factor affecting accuracy was confirmed in a separate multivariate analysis, where size was included in the model as a covariate(P = 0.018, OR = 1.08).Conclusion: Our study demonstrates that, in the absence of rapid on-site evaluation, mass size affects the accuracy of EUS-FNA of solid pancreatic lesions.

Cognitive impairment predicts mortality in outpatient veterans with heart failure

Background

In our prior study of 250 outpatient veterans with heart failure (HF), 58% had unrecognized cognitive impairment (CI) which was linked to worsened medication adherence. Literature suggests HF patients with CI have poorer clinical outcomes including higher mortality.

Effect of probiotic treatment on cirrhotic patients with minimal hepatic encephalopathy: A meta-analysis

Background: Minimal hepatic encephalopathy(MHE) is an early and reversible form of hepatic encephalopathy. The documentations on the treatment with probiotics are inconsistent. The present meta-analysis was to verify the role of probiotics in the treatment of cirrhotic patients with MHE.Data sources: Seven electronic databases were searched for relevant randomized controlled trials(RCTs)published until July 2015. The effects of probiotics on serum ammonia, endotoxin, and MHE were evaluated.Results: A total of 14 RCTs(combined n = 1132) were included in the meta-analysis. When probiotics were compared to placebo or no treatment, probiotics were more likely to reduce values in the number connection test(NCT; week 4: MD =-30.25, 95% CI:-49.85 to-10.66), improve MHE(week 4: OR = 0.18,95% CI: 0.07 to 0.47; week 12: OR = 0.15, 95% CI: 0.07 to 0.32), and prevent overt HE progression(week4: OR = 0.22, 95% CI: 0.07 to 0.67) in patients with liver cirrhosis. When probiotics was compared to lactulose, probiotics tended to reduce serum ammonia levels(week 4: MD =-0.33 μmol/L, 95% CI:-5.39 to 4.74; week 8: MD = 6.22 μmol/L, 95% CI:-24.04 to 36.48), decrease NCT(week 8: MD = 3.93, 95% CI:-0.72 to 8.58), improve MHE(week 4: OR = 0.93, 95% CI: 0.45 to 1.91; week 12: OR = 0.73, 95% CI: 0.35 to 1.51) and prevent the development of overt HE(week 4: OR = 0.96, 95% CI: 0.17 to 5.44; week 12:OR = 2.7, 95% CI: 0.50 to 14.64) in patients with liver cirrhosis. However, lactulose appears to be more effective in reducing NCT values as compared to probiotics(week 4: MD = 6.7, 95% CI: 0.58 to 12.82).Conclusion: Probiotics can decrease serum ammonia and endotoxin levels, improve MHE, and prevent overt HE development in patients with liver cirrhosis.     

Revision of bilateral self-expandable metallic stents placed using the stent-in-stent technique for malignant hilar biliary obstruction

Background

Endoscopic biliary decompression using bilateral self-expandable metallic stent (SEMS) placed using the stent-in-stent (SIS) technique is considered favorable for unresectable malignant hilar biliary obstruction (MHBO). However, occlusion of the bilateral SIS placement is frequent and revision can be challenging. This study was performed to investigate the efficacy, the long-term patency and the appropriate approach for revision of occluded bilateral SIS placement in unresectable MHBO.

Arterial Ischemic Events Are a Major Complication in Cancer Patients with Venous Thromboembolism

Background

Venous thromboembolism is common in patients with malignancies, affecting up to 10% of this patient population. The association between arterial ischemic events and venous thromboembolism also has been established. However, the influence of arterial ischemic events on outcomes in cancer patients with venous thromboembolism has not been fully determined.

Reducing Hospital Toxicity: Impact on Patient Outcomes

Background

Circadian rhythms are endogenous 24-hour oscillations in biologic processes that drive nearly all physiologic and behavioral functions. Disruption in circadian rhythms can adversely impact short- and long-term health outcomes. Routine hospital care often causes significant disruption in sleep-wake patterns that is further compounded by loss of personal control of health information and health decisions. We wished to evaluate measures directed at improving circadian rhythm and access to daily health information on hospital outcomes.

Usefulness of CA 19–9 for pancreatic cancer screening in patients with new-onset diabetes

Background: Generally, carbohydrate antigen 19–9(CA 19–9) is not useful for screening pancreatic cancer in the asymptomatic general population. This study aimed to evaluate the utility of CA 19–9 level as a screening indicator of pancreatic cancer in asymptomatic patients with new-onset diabetes.Methods: We retrospectively reviewed the medical records of patients who visited our health promotion center for health check-ups without cancer related symptoms from January 2005 to January 2014, and were newly diagnosed with diabetes mellitus(DM) within 2 years before their visit.Results: Of the 5111 asymptomatic patients with new-onset DM(2 years) selected for analyses, 87(1.7%) eventually developed pancreatic cancer after the health check-up. In the subgroup of 322 patients with high total bilirubin levels(1.7 mg/d L) at the screening time, 42(73.7%) of 57 patients with high CA19–9 levels(37 IU/m L) had been diagnosed as pancreatic cancer during follow-up period and 12(4.5%)of 265 patients with normal CA 19–9 levels had finally developed pancreatic cancer(OR = 16.3). In the subgroup of 4789 patients with normal bilirubin levels, pancreatic cancer had been detected in 20(3.8%)of 522 patients with high CA 19–9 level, while only 13(0.3%) in 4267 patients with normal CA 19–9 levels(OR = 12.6), respectively.Conclusion: CA 19–9 levels after a diagnosis of new-onset DM could be a useful biomarker of pancreatic cancer, especially in patients with high serum bilirubin.     

Short-Term Prognosis of Myocardial Injury,Type 1, and Type 2 Myocardial Infarction in the Emergency Unit

However, their respective frequencies, risk profiles, and short-term prognoses remain to be investigated.

Serum levels of miRNA in patients with hepatitis B virus-associated acute-on-chronic liver failure

Background: Hepatitis B virus(HBV)-associated acute-on-chronic liver failure(HBV-ACLF) is a lifethreatening condition and its exact pathophysiology and progression remain unclear. The present study aimed to assess the role of serum mi RNAs in the evaluation of HBV-ACLF and to develop a model to predict the outcomes for ACLF.Methods: Serum was collected from 41 chronic hepatitis B and 55 HBV-ACLF patients in addition to30 chronic asymptomatic HBV carriers as controls. The mi RNAs expressions were measured by real-time quantitative PCR(q-PCR). Statistical analyses were conducted to assess the ability of differentially expressed mi RNAs and other prognostic factors in identifying ACLF prognosis and to develop a new predictive model.Results: Real-time q-PCR indicated that serum miR-146 a-5 p, mi R-122-3 p and mi R-328-3 p levels were significantly upregulated in ACLF patients compared to chronic hepatitis B and chronic asymptomatic HBV carriers patients. In addition, multivariate regression analyses indicated that Na+, INR, gastrointestinal bleeding and mi R-122-3 p are all independent factors that are reliable and sensitive to the prognosis of HBV-ACLF. Therefore, we developed a new model for the prediction of HBV-ACLF disease state: Y = 0.402 × Na+-1.72 × INR-4.963 × gastrointestinal bleeding(Yes = 0; No = 1)-0.278 ×(mi R-122-3 p) + 50.449. The predictive accuracy of the model was 95.3% and the area under the receiver operating characteristic curve(AUROC) was 0.847.Conclusions: Expression levels of these mi RNAs(miR-146 a-5 p, mi R-122-3 p and mi R-328-3 p) positively correlate with the severity of liver inflammation in patients with ACLF and may be useful to predict HBV-ACLF severity.     

Assessment of clinical outcomes of advanced hilar cholangiocarcinoma

Background: Low resectability and poor survival outcome are common for hilar cholangiocarcinoma(HCCA), especially in advanced stages. The present study was to assess the clinical outcome of advanced HCCA, focusing on therapeutic modalities, survival analysis and prognostic assessment.Methods: Clinical data of 176 advanced HCCA patients who had been treated in our hospital between January 2013 and December 2015 were analyzed retrospectively. Prognostic effects of clinicopathological factors were explored by univariate and multivariate analysis. Survival predictors were evaluated by the receiver operating characteristic(ROC) curve.Results: The 3-year overall survival rate was 13% for patients with advanced HCCA. Preoperative total bilirubin(P = 0.009), hepatic artery invasion(P = 0.014) and treatment modalities(P = 0.020) were independent prognostic factors on overall survival. A model combining these independent prognostic factors(area under ROC curve: 0.748; 95% CI: 0.678–0.811; sensitivity: 82.3%, specificity: 53.5%) was highly predictive of tumor death. After R0 resection, the 3-year overall survival was up to 38%. Preoperative total bilirubin was still an independent negative factor, but not for hepatic artery invasion.Conclusions: Surgery is still the best treatment for advanced HCCA. Preoperative biliary drainage should be performed in highly-jaundiced patients to improve survival. Prediction of survival is improved significantly by a model that incorporates preoperative total bilirubin, hepatic artery invasion and treatment modalities.     

Utilization of Vasculoprotective Therapy for Peripheral Artery Disease: A Systematic Review and Meta-analysis

Introduction

Practice guidelines recommend that patients with peripheral artery disease receive antiplatelets, statins, and angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs). We sought to quantify the rates of prescribing these therapies in patients with peripheral artery disease in the literature.

Association of Long-Term Diet Quality with Hippocampal Volume: Longitudinal Cohort Study

BACKGROUND

Diet quality is associated with brain aging outcomes. However, few studies have explored in humans the brain structures potentially affected by long-term diet quality. We examined whether cumulative average of the Alternative Healthy Eating Index 2010 (AHEI-2010) score during adult life (an 11-year exposure period) is associated with hippocampal volume.

Various approaches of laparoscopic common bile duct exploration plus primary duct closure for choledocholithiasis: A systematic review and meta-analysis

Background: Common bile duct(CBD) stones may occur in up to 3%–14.7% of all patients with cholecystectomy. Various approaches of laparoscopic CBD exploration plus primary duct closure(PDC) are the most commonly used and the best methods to treat CBD stone. This systematic review was to compare the effectiveness and safety of the various approaches of laparoscopic CBD exploration plus PDC for choledocholithiasis.Data sources: Randomized controlled trials(RCTs) and non-randomized controlled trials(NRCTs)(casecontrol studies or cohort studies) were searched from Cochrane library(until Issue 2, 2015), Web of Science(1980-January 2016), Pub Med(1966-January 2016), and Baidu search engine. After independent quality assessment and data extraction, meta-analysis was conducted using Rev Man 5.1 software.Results: Four RCTs and 18 NRCTs were included. When compared with choledochotomy exploration(CE) plus T-tube drainage(TTD)(CE + TTD), CE plus PDC(CE + PDC) and CE + PDC with biliary drainage(BD)(CE + PDC + BD) had a lower rate of postoperative biliary peritonitis(OR = 0.22; 95% CI: 0.06, 0.88;P 0.05; OR = 0.27; 95% CI: 0.08, 0.84; P 0.05; respectively) where T-tubes were removed more than3 weeks. The operative time of CE + PDC was significantly shorter(WMD =-24.82; 95% CI:-27.48,-22.16; P 0.01) than that of CE + TTD in RCTs. Cystic duct exploration(CDE) plus PDC(CDE + PDC) has a lower rate of postoperative complications(OR = 0.39; 95% CI: 0.23, 0.67; P 0.01) when compared with CE + PDC. Confluence part micro-incision exploration(CME) plus PDC(CME + PDC) has a lower rate of postoperative bile leakage(OR = 0.17; 95% CI: 0.04, 0.74; P 0.05) when compared with CE + PDC.Conclusion: PDC with other various approaches are better than TTD in the treatment of choledocholithiasis.     

Long-term outcomes of endoscopic papillary balloon dilation for removal of bile duct stones in Billroth Ⅱ gastrectomy patients

Background: Endoscopic papillary balloon dilation(EPBD) for common bile duct(CBD) stones removal in Billroth Ⅱ gastrectomy patients is feasible. However, the long-term outcomes of this technique are not clear. The aim of this study was to evaluate the procedural and long-term outcomes of EPBD for removal of CBD stones in Billroth Ⅱ gastrectomy patients.Methods: The records of patients with previous Billroth Ⅱ gastrectomy referred for CBD stones removal with endoscopic retrograde cholangiopancreatography(ERCP) between July 1, 2008 and September 1,2016 were retrospectively reviewed. The main outcomes of stone clearance, ERCP-related adverse events,and stone recurrence were analyzed.Results: A total of 83 patients with previous Billroth Ⅱ gastrectomy underwent ERCP in our center were reviewed. Forty-nine consecutive patients with previous Billroth Ⅱ gastrectomy referred to EPBD for removal of CBD stones underwent 59 ERCP procedures were enrolled in the end. The overall successful CBD stones clearance was achieved in 42 patients(85.7%). ERCP-related adverse events was in 3 ERCP procedures(5.1%). Severe complications, including perforation and bleeding, were not observed. Six of 49 patients(12.2%) had stone recurrence after a median period of22.5 months(range 6–71 months) from the end of stone removal treatment. Female [odds ratio(OR) = 11.352; 95% confidence interval(95% CI): 1.040–123.912; P = 0.046] and previous mechanical lithotripsy(OR = 13.423; 95% CI: 1.070–168.434; P = 0.044) were significantly associated with stone recurrence.Conclusions: At long-term follow-up, EPBD for removal of CBD stones appeared to be safe and effective in Billroth Ⅱ gastrectomy patients. Female and previous mechanical lithotripsy may be risk factors for stone recurrence.     

Protocol driven palliative care consultation: Outcomes of the ENABLE CHF-PC pilot study

Background

Little has been reported about protocol-driven outpatient palliative care consultation (OPCC) for advanced heart failure (HF).
