Objective Cholangiocarcinoma (CCA) affects all ethnicities worldwide. The Hispanic population being the leading ethnic minority in the United States, its importance to the healthcare system cannot be understated. This study aims to assess the occurrence and outcomes of CCA in Hispanic patients in the United States. Methods This is a case-control study using the National Inpatient Sample 2014. All patients with ICD-9 CM codes for CCA were included. Hispanic patients were identified from the ethnic categories within the database. The primary outcomes were the occurrence and odds of CCA in the Hispanic population when compared with other ethnicities. Secondary outcomes were inpatient mortality, morbidity, ICU stay, multiorgan failure, and resource utilization. Results A total of 13 965 patients with CCA were identified, of which 2750 were propensity-matched to controls (1480 Hispanic). The inpatient occurrence of CCA in Hispanics relative to the national population was 2.73/100 000 persons, compared to 4.82/100 000 persons (39.9/100 000 relative to inpatient population) of all other ethnicities. After adjusting for confounders on multivariate analysis, Hispanic patients displayed adjusted propensity-matched odds of 1.28 (P < 0.01) of having CCA when compared with other ethnicities. Hispanics did not display different propensity-matched odds of inpatient mortality, morbidity, hospital length of stay, or resource utilization compared to non-Hispanic patients. Conclusion This study demonstrated that the odds of CCA in admitted patients are higher for the Hispanic population. This difference with the prevalence potentially suggests the presence of social factors such as disparities in cancer prevention or detection in this group.

INTRODUCTION: Gender in ulcerative colitis (UC) is a well-studied topic with contradicting results with a slight male predominance seen in large population based studies in Olmsted County, Minnesota, while other studies have shown a slight female predominance. Yet, the relationship between UC and gender is not well-understood. Hence, it is unclear what is responsible for differences in gender. The aim of this study is to assess the inpatient prevalence and inpatients outcomes of UC by gender. METHODS: Case-control study using the NIS 2016, the largest public inpatient database in the US. All patients with ICD9-10CM codes for UC were included. None were excluded. Female patients were identified within the database using the female gender indicator. The primary outcome was determining the odds of UC in female patients compared to males. Secondary outcomes included determining inpatient morbidity, mortality, resource utilization, colectomy rates, hospital length of stay (LOS), and inflation-adjusted total hospital costs and charges. Propensity score matching was used to create a matching population for Charlson Comorbidity Index and age. Multivariate regression analyses were used to adjust for income in patient zip code, hospital region, location, size and teaching status. RESULTS: A total of 38, 950 patients with UC were identified and propensity matched for selected covariates. The mean patient age was 45, and 47.2% were female. For the primary outcome, females had decreased adjusted odds (aOR: 0.92, P < 0.01) of being admitted for UC. For secondary outcomes, female patients displayed lower adjusted odds of multi-organ failure, being placed on TPN, and undergoing colectomy. Females also had lower adjusted mean hospital costs, charges, and length of stay (LOS). All adjusted odds and means are displayed in Table 1. CONCLUSION: Females have lower inpatient prevalence of UC, complications, and economic burden compared to males. This reinforces the slight male predominance that was seen in the older Olmstead County population-based studies. One can speculate that the difference in complications, costs, charges, and LOS indicate that females have less severe disease at hospital admission. Numerous studies have examined the effect of gender on disease severity and outcomes, and there continues to be conflicting data. Thus, future studies are needed to determine what contributes to the variation in disease prevalence and course by gender, and possibly better tailor treatment regimens by gender.

Objectives Recent studies have suggested that small intestinal bacterial overgrowth (SIBO) could be a predisposing factor for nonalcoholic fatty liver disease (NAFLD) although the results were inconsistent. This systematic review and meta-analysis was conducted with the aim to summarize all available data. Methods A comprehensive literature review was conducted utilizing MEDLINE and EMBASE databases through September 2018 to identify all studies that compared the risk of NAFLD among patients with SIBO versus those without SIBO. Effect estimates from each study were extracted and combined together using the random effect, generic inverse variance method of DerSimonian and Laird. Results A total of 10 studies with 1093 participants fulfilled the eligibility criteria and were included in the meta-analysis. A significant association between NAFLD and SIBO was observed with the pooled odds ratio of 3.82 (95% confidence interval, 1.93–7.59; I 2 65%). Funnel plot is relatively symmetric and is not suggestive of the presence of publication bias. Conclusion A significant association between NAFLD and SIBO was observed in this meta-analysis.

AbstractBackground/objectivesSeveral epidemiologic studies have suggested that patients with celiac disease may be at an increased risk of sarcoidosis but the results were inconsistent. This systematic review and meta‐analysis was conducted with the aim to better characterize this risk by summarizing all available data.MethodsA literature review was performed using MEDLINE and EMBASE database from inception to February 2019. Studies that compared the risk of sarcoidosis among patients with celiac disease versus individuals without celiac disease were included. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using a random‐effect, generic inverse variance method.ResultsOf 426 retrieved studies, four studies with 693 639 participants met the eligibility criteria and were included in meta‐analysis. The risk of sarcoidosis among patients with celiac disease was higher than individuals without celiac disease with the pooled OR of 7.16 (95% CI, 1.48‐34.56). The statistical heterogeneity of this study was high (I2 = 95%).ConclusionsThis systematic review and meta‐analysis found a significantly higher risk of sarcoidosis among patients with celiac disease.

Background/ObjectivesA negative association between cigarette smoking and celiac disease has been observed but results were inconsistent across the published studies. A meta‐analysis was conducted with the aim to identify all studies that investigated this association and to summarize the results of those studies.MethodsA comprehensive literature review was conducted utilizing MEDLINE and Embase databases through March 2018 to identify all cohort studies and case‐control studies that compared the risk of celiac disease among current and/or former smokers versus never‐smokers. Effect estimates from each study were extracted and combined together using the random‐effect, generic inverse variance method of DerSimonian and Laird.ResultsA total of seven studies with 307,924 participants fulfilled the eligibility criteria and were included in the meta‐analysis. The pooled analysis found a significantly decreased risk of celiac disease among current smokers compared with never‐smokers with the pooled odds ratio (OR) of 0.52 (95% confidence interval (CI), 0.32–0.84; I2 86%). However, the risk of celiac disease among former smokers was not significantly different from never‐smokers with the pooled OR of 1.10 (95% CI, 0.76–1.60; I2 of 73%).ConclusionsA significantly decreased risk of celiac disease among current smokers compared with never‐smokers was demonstrated in this meta‐analysis.

Abstract Background Volumetric laser endomicroscopy (VLE) provides circumferential images 3 mm into the biliary and pancreatic ducts. We aimed to correlate VLE images with the normal and abnormal microstructure of these ducts. Methods: Samples from patients undergoing hepatic or pancreatic resection were evaluated. VLE images were collected using a low-profile VLE catheter inserted manually into the biliary and pancreatic ducts ex vivo. Histological correlation was assessed by two unblinded investigators. Results 25 patients (20 liver and 5 pancreatic samples) and 111 images were analyzed. VLE revealed three histological layers: epithelium, connective tissue, and parenchyma. It identified distinctive patterns for primary sclerosing cholangitis (PSC), pancreatic cysts, neuroendocrine tumor, and adenocarcinoma adjacent to the pancreatic duct or ampulla. VLE failed to identify dysplasia in a dominant stricture and inflammatory infiltrates in PSC. Reflectivity measurements of the liver parenchyma diagnosed liver cirrhosis with high sensitivity. Conclusions VLE can identify histological changes in the biliary and pancreatic ducts allowing real-time diagnosis. Further studies are needed to measure the accuracy of VLE in a larger sample and to validate our findings in vivo.

Objectives. Surgery is the most effective treatment for pancreatic cancer. However, present literature varies on outcomes of curative pancreatic resection in the elderly. The objective of the study was to evaluate age as an independent risk factor for 90-day mortality and complications after pancreatic resection. Methods. Nine hundred twenty-nine consecutive patients underwent 934 pancreatic resections between March 1995 and July 2014 in a tertiary care center. Primary analyses focused on outcomes in terms of 90-day mortality and postoperative complications after pancreatic resection in these two age groups. Results. Even though patients aged 75 years or older had significantly more postoperative morbidities compared with the younger patient group, the age group was not associated with increased risk of 90-day mortality after pancreatic resection. Discussion. The study suggests that age alone should not preclude patients from undergoing curative pancreatic resection.
