AIM To examine the association between the timing of endo-scopy and the short-term outcomes of acute variceal bleeding in cirrhotic *** This retrospective study included 274 consecutive patients admitted with acute esophageal variceal bleeding of two tertiary hospitals in Korea. We adjusted confounding factors using the Cox proportional hazards model and the inverse probability weighting （IPW） method. The primary outcome was the mortality of patients within 6 *** A total of 173 patients received urgent endoscopy （ i.e. , ≤ 12 h after admission）, and 101 patients received non-urgent endoscopy （〉 12 h after admission）. The 6-wk mortality rate was 22.5% in the urgent endoscopy group and 29.7% in the non-urgent endoscopy group, and there was no significant difference between the two groups before （P = 0.266） and after IPW （P = 0.639）. The length of hospital stay was statistically different between the urgent group and non-urgent group （P = 0.033）; however, there was no significant difference in the in-hospital mortality rate between the two groups （8.1%vs 7.9%, P = 0.960）. In multivariate analyses, timing of endoscopy was not associated with 6-wk mortality （hazard ratio, 1.297; 95% confdence interval, 0.806-2.089; P = 0.284）.CONCLUSION In cirrhotic patients with acute variceal bleeding, the timing of endoscopy may be independent of short-term mortality.

Decellularized sciatic nerve matrix as a biodegradable conduit for peripheral nerve regeneration

The use of autologous nerve grafts remains the gold standard for treating nerve defects, but current nerve repair techniques are limited by donor tissue availability and morbidity associated with tissue loss. Recently, the use of conduits in nerve injury repair, made possible by tissue engineering, has shown therapeutic potential. We manufactured a biodegradable, collagen-based nerve conduit containing decellularized sciatic nerve matrix and compared this with a silicone conduit for peripheral nerve regeneration using a rat model. The collagen-based conduit contains nerve growth factor, brain-derived neurotrophic factor, and laminin, as demonstrated by enzyme-linked immunosorbent assay. Scanning electron microscopy images showed that the collagen-based conduit had an outer wall to prevent scar tissue infiltration and a porous inner structure to allow axonal growth. Rats that were implanted with the collagen-based conduit to bridge a sciatic nerve defect experienced significantly improved motor and sensory nerve functions and greatly enhanced nerve regeneration compared with rats in the sham control group and the silicone conduit group. Our results suggest that the biodegradable collagen-based nerve conduit is more effective for peripheral nerve regeneration than the silicone conduit.

Intracardic air embolism is uncommon, however it is a serious condition which frequently leads to catastrophic complications during or after invasive procedures resulting in significant morbidity and mortality. For a successful re- suscitation of patients with intracardiac air embolism, hy- perbaric oxygen therapy is critical.~~2~ Still, due to a hyper- baric chamber＇s unavailability at many hospitals and con- cerns about patient movement resulting in further embolism during transport, such treatment method is gradually dimin- ishing.

Objective： Chemoport-related thrombosis （CRT） is a serious complication that causes morbidities and interruptsadministration of intravenous cancer therapy. We investigated the incidence and risk of CRT in colorectal cancer（CRC） patients treated with bevacizumab （BEV）.Methods： We retrospectively reviewed 1,534 CRC patients who received chemotherapy with or without BEVusing a chemoport between 2014 and ***： The participants had a median age of 58 （18-85） years, and 60.3% were male. All participants werestratified into three groups： adjuvant chemotherapy （AC）（n=670）, palliative chemotherapy （PC） without BEV（n=356）, and PC with BEV （n=508）. The median follow-up was 20.19 （interquartile range, 14.07-27.19） *** occurred in 3.8% of all patients; incidence of symptomatic and asymptomatic CRT was 2.9% and 0.9%,respectively. CRT occurred more in patients with BEV （5.7%） than in patients without BEV （2.9%, P=0.008）. Thecumulative incidence of CRT in patients administered PC with BEV was significantly higher than that in thoseadministered AC （P=0.011） and there was a trend toward increased CRY in patients administered PC with BEVcompared with those administered PC without BEV （P=0.044）. Multivariate analysis found that BEV treatment wasthe only variable that was significandy associated with CRT （hazard ratio, 2.06; 95% confidence interval, 1.24-3.43;P=0.006）.Conclusions： BEV treatment was significandy associated with increased incidence of CRT in CRC patients.

The technique of region of interest-based positron emission tomography is limited by its poor reli-ability and relatively few examined brain regions. In the present study, we compared brain metabo-lism assessed using fluorine-18-fluorodeoxyglucose positron emission tomography between 14 at-tention-deficit hyperactivity disorder （ADHD） patients and 15 normal controls with scoliosis at resting state by statistical parametric mapping. Glucose metabolism was decreased in the left parahippo-campal gyrus, left hippocampus, left anterior cingulate gyrus, right anterior and posterior lobes of the cerebellum, left superior temporal gyrus, left insula, left medial and middle frontal gyri, right medial frontal gyrus, and left basal ganglia （putamen, amygdala, and caudate nucleus） in children with ADHD. These data suggest that children with ADHD exhibit hypometabolism in various brain regions compared to controls, indicating that ADHD symptoms are unlikely the result of abnormalities in specific areas.

Background There are numerous but conflicting data regarding gender differences in outcomes following percutaneous coronary intervention(PCI). Furthermore, gender differences in clinical outcomes with acute myocardial infarction(AMI) following PCI in Asian population remain uncertain because of the under-representation of Asian in previous trials. Methods A total of 13,104 AMI patients from Korea Acute Myocardial Infarction Registry-National Institute of Health(KAMIR-NIH) between November 2011 and December 2015 were classified into male(n = 8021, 75.9%) and female(n = 2547, 24.1%). We compared the demographic, clinical and angiographic characteristics, 30-days and 1-year major adverse cardiac and cerebrovascular events(MACCE) in women with those in men after AMI by using propensity score(PS) matching. Results Compared with men, women were older, had more comorbidities and more often presented with non-ST segment elevation myocardial infarction(NSTEMI) and reduced left ventricular systolic function. Over the median follow-up of 363 days, gender differences in both 30-days and 1-year MACCE as well as thrombolysis in myocardial infarction minor bleeding risk were not observed in the PS matched population(30-days MACCE: 5.3% vs. 4.7%, log-rank P = 0.494, HR = 1.126, 95% CI: 0.800-1.585;1-year MACCE: 9.3% vs. 9.0%, log-rank P = 0.803, HR = 1.032, 95% CI: 0.802-1.328;TIMI minor bleeding: 4.9% vs. 3.9%, log-rank P = 0.215, HR = 1.255, 95% CI: 0.869-1.814). Conclusions Among Korean AMI population undergoing contemporary PCI, women, as compared with men, had different clinical and angiographic characteristics but showed similar 30-days and 1-year clinical outcomes. The risk of bleeding after PCI was comparable between men and women during one-year follow up.

Evidence from a familial case suggests maternal inheritance of primary biliary cholangitis

引用

World Journal of Gastroenterology 2017年第39期23卷 7191-7197页

作者： Saeam Shin In Ho Moh Young Sik Woo Sung Won Jung jin Bae Kim ji Won Park Ki Tae Suk Hyoung Su Kim Mineui Hong Sang hoon Park Myung Seok lee Department of Laboratory Medicine Kangnam Sacred Heart Hospital Hallym University College of Medicine Division of Gastroenterology and Hepatology Department of Internal Medicine Kangnam Sacred Heart Hospital Hallym University College of Medicine Department of Pathology Kangnam Sacred Heart Hospital Hallym University College of Medicine

Primary biliary cholangitis(PBC) is an idiopathic autoimmune liver disease characterized by chronic cholestasis and destruction of the intrahepatic bile ducts. Similar to other autoimmune diseases, the pathogenesis of PBC is considered to be a complex etiologic phenomenon involving the interaction of genetic and environmental factors. Although a number of common variants associated with PBC have been reported from genome-wide association studies, a precise genetic mechanism underlying PBC has yet to be identified. Here, we describe a family with four sisters who were diagnosed with PBC. After the diagnosis of the index patient who was in an advanced stage of PBC, one sister presented with acute hepatitis, and two sisters were subsequently diagnosed with PBC. Notably, one half-sister with a different mother exhibited no evidence of PBC following clinical investigation. Our report suggests the possibility of a maternal inheritance of PBC susceptibility. Moreover, judging from the highpenetrance of the disease observed in this family, we inferred that a pathogenic genetic variant might be the cause of PBC development. We describe a family that exhibited diverse clinical presentations of PBC that included asymptomatic stages with mildly increased liver enzyme levels and symptomatic stages with acute hepatitis or advanced liver fibrosis. Additional studies are needed to investigate the role of genetic factors in the pathogenesis of this rare autoimmune disease.
