Serum ammonia could predict the presence of EV using a cutoff value of 82 (µmol/L) with a sensitivity of 92.3%, specificity 92%. In addition, a cutoff of 95.5 (µmol/L) could predict large EV with a sensitivity of 92.7% and a specificity of 92.3%. Serum Ammonia in cirrhosis with large EV was 143 ± 39 µmol/L and in cirrhosis with small/without EV was 80.7 ± 9.7 µmol/L (P less then 0.0001). Platelet/spleen ratio was 555.9 ± 187.3 in cirrhosis with EV and 694.4 ± 74.2 in cirrhosis without EV (P less then 0.0001). Platelet/spleen ratio was 407.7 ± 107.1 in cirrhosis with large EV and 690.4 ± 103.7 in cirrhosis with small/without EV (P less then 0.0001). CONCLUSION Serum ammonia can accurately predict the presence and the size of EV in patients with liver cirrhosis with high sensitivity and specificity.OBJECTIVES Hepatitis B virus reactivation in patients on immunosuppressive therapy is a critical issue. We aimed to verify the monitoring strategies of hepatitis B virus DNA and quantitative hepatitis B surface antigen in patients receiving therapies with moderate risk. METHODS We enrolled 25 patients with autoimmune diseases receiving immunosuppressive therapy. Liver function, hepatitis B virus DNA, and quantitative hepatitis B surface antigen were followed-up every 2 months for 24 months. The hepatitis B virus reactivation was defined as hepatitis B virus DNA reappearance or increase of >1 log IU/mL. RESULTS Patients who were hepatitis B surface antigen positive with (n = 12) or without (n = 6) antiviral prophylaxis and hepatitis B surface antigen negative (n = 7) were analyzed, and the reactivation rates were 0%, 50% and 14%, respectively. Antiviral prophylaxis prevented hepatitis B virus reactivation in hepatitis B surface antigen-positive patients (P = 0.025). Administration of high-risk steroid doses was the sole factor related to the sign of quantitative hepatitis B surface antigen increase of >0.5 log IU/mL in the first 12 months (P = 0.035, risk ratio = 0.098, 95% confidence interval = 0.011-0.847). Furthermore, no patient experienced hepatic decompensation or failure. CONCLUSION Monitoring hepatitis B virus DNA and quantitative hepatitis B surface antigen every 2 months is safe. However, antiviral prophylaxis can prevent hepatitis B virus reactivation. For patients under steroid therapy in high-risk doses, quantitative hepatitis B surface antigen increase of >0.5 log IU/mL may signify hepatitis B virus reactivation.BACKGROUND The incidence and mortality of colorectal cancer (CRC) are increasing in adults under 50 years. Risk factors associated with early-onset colorectal neoplasia (CRN) are uncertain. We aimed to identify clinical predictors associated with the presence of CRN detected by diagnostic colonoscopy in symptomatic individuals under 50 years of age. METHODS We used a single-center endoscopy database to identify symptomatic patients 18-49 years of age who underwent ambulatory colonoscopy between 2007 and 2017. Pathology reports identified CRN as adenomas, advanced adenomas (based on size or histology), or adenocarcinomas. Multivariable analysis was used to determine factors associated with CRN. RESULTS We identified 4333 eligible patients of whom 363 (8.4%) had any CRN and 48 (1.1%) had advanced neoplasia (advanced adenoma or adenocarcinoma). Factors associated with any CRN on multivariable analysis included male sex [odds ratio (OR) 1.50 (1.19-1.88)], older age group [compared to 18-29 years, OR for 30-39 3.12 (1.93-5.04); OR for 40-49 4.68 (2.97-7.36)], obesity [OR for BMI 30-34.9 compared to 18-24.9 1.44 (1.04-2.01)], and any tobacco use [OR 1.63 (1.18-2.23)]. Anemia was associated with advanced neoplasia [OR 3.11 (1.32-7.34)]. Of the advanced neoplastic lesions, 38 of 48 (79.2%) were located in the distal colon. CONCLUSIONS In the largest study to date of symptomatic individuals under 50 years of age undergoing colonoscopy in the USA, advanced CRN was most often detected in the distal colon and was associated with anemia, but not with abnormal bowel habits or abdominal pain. We also found that patients with CRN under 50 years of age were more likely to be male, smokers, and obese. These findings should prompt further investigation of these risk factors alone and in combination.BACKGROUND Moderate-to-severe mitral regurgitation is present in 20-35% of patients undergoing transcatheter aortic valve replacement (TAVR) and the current literature lacks simple echocardiographic parameters, which can predict post-TAVR changes in mitral regurgitation. The aim of this study is to investigate the echocardiographic predictors of improvement or worsening of mitral regurgitation in patients undergoing TAVR with moderate-to-severe mitral regurgitation. METHODS This retrospective study included 113 patients who underwent TAVR with preoperative mitral regurgitation grade at least 2. Patients with concomitant coronary artery disease requiring treatment were excluded. Mitral regurgitation was related to the annular dilatation or tethering mechanism in all patients. Preoperative and postoperative echocardiographies were compared in terms of mitral regurgitation and other commonly measured parameters. RESULTS After TAVR, a reduction in mitral regurgitation was observed in 62.8% of cases. On the basis m outcomes are warranted to support those conclusions.BACKGROUND/OBJECTIVES Little is known about atrial involvement in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). Recent studies have suggested that atrial arrhythmia, including atrial fibrillation, atrial flutter (AFL), and atrial tachycardia, was common among these patients although the reported prevalence varied considerably across the studies. The current systematic review and meta-analysis was conducted with the aim of comprehensively investigating the prevalence of overall atrial arrhythmia and each atrial arrhythmia subtype in the setting of ARVC by identifying all relevant studies and combining their results together. METHODS A comprehensive literature review was conducted by searching for published articles indexed in MEDLINE and EMBASE databases from inception through to 22 September 2019 to identify cohort studies of patients with ARVC that described the prevalence of atrial arrhythmia among the participants. AZD7648 The pooled prevalence across studies was calculated using a random-effect, generic inverse variance method of DerSimonian and Laird with a double arcsine transformation.
