uding sepsis, subpopulations of IBD patients, especially those undergoing strong immunosuppression might benefit from additional urolithiasis screening.

Data on the accuracy of the diagnosis of hepatopulmonary syndrome (HPS) in cirrhosis is limited. We evaluated the clinical characteristics of patients with International Classification of Diseases (ICD) codes for hepatopulmonary syndrome (HPS) in a large integrated health system.

A retrospective review of encounters was performed of all patients with ICD-9-CM and/or ICD-10-CM diagnosis of cirrhosis and HPS from 2014-2019 in a multi-state health system. Demographics and cardiopulmonary testing closest to the time of HPS diagnosis were recorded. HPS was defined using standard criteria.

A total of 42,749 unique individuals with cirrhosis were identified. An ICD diagnosis of HPS was found in 194 patients (0.45%), of which 182 had clinically confirmed cirrhosis. 143 (78.5%) underwent contrast-enhanced transthoracic echocardiography, and 98 (54%) had delayed shunting. Among them, 61 patients had a documented arterial blood gas, with 53 showing abnormal oxygenation (A-a gradient of >15 mm Hg). 12 were exclumproved education and more effective screening algorithms.

The latitudinal gradient effect is described for several autoimmune diseases including celiac disease in the United States. However, the association between latitude and global celiac disease prevalence is unknown. We aimed to explore the association between latitude and serology-based celiac disease prevalence through meta-analysis.

We searched MEDLINE, Embase, Cochrane, and Scopus databases from their beginning through June 29, 2018, to identify screening studies that targeted a general population sample, used serology-based screening tests, and provided a clear location from which we could assign a latitude. Studies were excluded if sampling was based on symptoms, risk factors, or referral. Study selection and data extraction were performed by independent reviewers. The association measures between latitude and prevalence of serology-based celiac disease were evaluated with random-effects meta-analyses and meta-regression.

Of the identified 4667 unique citations, 128 studies were included, with 155 prevalence estimates representing 40 countries. read more Celiac disease was more prevalent at the higher latitudes of 51° to 60° (relative risk [RR], 1.62; 95% CI, 1.09-2.38) and 61° to 70° (RR, 2.30; 95% CI, 1.36-3.89) compared with the 41° to 50° reference level. No statistically significant difference was observed at lower latitudes. When latitude was treated as continuous, we found a statistically significant association between CD prevalence and latitude overall in the world (RR, 1.03, 95% CI, 1.01-1.05) and a subregional analysis of Europe (RR, 1.05; 95% CI, 1.02-1.07) and North America (RR, 1.1; 95% CI, 1.0-1.2).

In this comprehensive review of screening studies, we found that a higher latitude was associated with greater serology-based celiac disease prevalence.

In this comprehensive review of screening studies, we found that a higher latitude was associated with greater serology-based celiac disease prevalence.Nonalcoholic fatty liver disease (NAFLD), the most common cause of chronic liver disease,1 is independently associated with increased risk of cardiovascular disease (CVD), which is the leading cause of mortality in patients with NAFLD.2 This is likely caused by the centrality of the liver in lipid homeostasis. Prior cross-sectional studies have shown that NAFLD is associated with perturbations in lipid profile and atherogenic lipoprotein subparticles.3 Although statins improve lipid profile and CVD-associated mortality, residual CVD risk has been demonstrated in major statin trials.4,5 A key contributor to this residual risk is the limited ability of the standard lipid profile to precisely quantify atherogenic lipoprotein subparticles, such as small dense low-density lipoprotein (sdLDL), which might confer higher atherogenic risk. There are currently no studies evaluating the longitudinal impact of sdLDL on atherosclerotic events in NAFLD. Thus, we conducted a prospective study in patients with histologically confirmed NAFLD to better define the relationship among NAFLD, residual CVD risk, and sdLDL.Oxaliplatin is an alkylating agent given with fluorouracil and leucovorin as a mainstay adjuvant chemotherapy for stage III colorectal cancer (CRC). Liver injury from oxaliplatin ranges from mild liver enzyme increases in 42% to 57% of patients in clinical trials1 to rare severe injury leading to acute liver failure.2 Chronic injury from endothelial cell damage and architectural distortion may manifest years later with nodular regenerative hyperplasia (NRH), portal sclerosis, and noncirrhotic portal hypertension (NCPH).2,3 Chronic subclinical injury occurs in up to 78% of patients.3 Diagnosis may be confounded by nonalcoholic fatty liver disease (NAFLD), and long-term outcomes from chronic injury are unclear.A novel kind of anti-cancer pharmacosome (named NPC-D) derived from Doxifluridine (5′-DFUR) was described, which could be activated by tumor microenvironments (TMEs). The NPC-D with H2O2-sensitive linker was dispersed well in water and simultaneously interacted with nucleic acids including plasmids encoding miR-122 (p122) and EpCAM-targeted aptamer (ap1) via charge interaction and hydrogen bonding. The integrated nanosystem (p122-ap1@NPC-D) was found to unleash by programmed TMEs (high level of H2O2 and low pH) to efficiently transfect miR-122 into MHCC-LM3 cells, followed by the releases of 5-FU. Besides, p122-ap1@NPC-D significantly countered the chemotherapy resistance and played a synergistic effect. These unique nanoparticles dramatically enhanced the anti-proliferation, and modulated the cellular apoptosis by the down-regulation of various signal pathways which imparted a bright application prospect in HCC treatment.The biofilm of Bacillus cereus on the surface of X80 pipeline steel was investigated from forming to shedding. Based on the observed biofilm morphology and pit analysis, it was found that B. cereus biofilm could stimulate X80 pipeline steel pitting corrosion, which was attributed to the nitrate reduction of bacteria beneath the biofilm. Electrochemical measurements and general corrosion rate results showed that B. cereus biofilm can better accelerate X80 pipeline steel corrosion compared to sterile solutions. Interestingly, the results also showed that thick biofilms had a slight tendency to inhibit the general corrosion process compared with its formation and exfoliation, which was confirmed by scanning Kelvin probe. The corrosion rate of X80 pipeline steel in artificial Beijing soil is closely related to the state of the biofilm, and nitrate reducing bacteria accelerates the occurrence of pits. The corresponding corrosion mechanisms are proposed.
