Background and Aims: Appendectomy is the choice of surgery for appendicitis but little is known about its outcomes in patients with Inflammatory Bowel Disease (IBD). We sought to compare hospital outcomes of appendectomy for appendicitis between patients with and without IBD. Methods: This is a cross-sectional study utilizing the Nationwide Inpatient Sample between 2009 and 2013. Patients with appendicitis undergoing appendectomy were identified using appropriate International Classification of Diseases codes. Primary outcomes of interest included length of stay (LOS), hospital costs, and post-surgical complications. Univariate and multivariate analyses were used to compare these outcomes between patients with and without IBD. Results: A total of 849,312 patients with appendicitis undergoing appendectomy were included in this study, of which 4261 patients had IBD. IBD patients had longer LOS and increased hospital costs. Crohn’s disease (CD) patients were more likely to develop post-operative pulmonary embolism (adjusted odds ratio (aOR) 7.06, 95% Confidence Interval (CI) (2.19, 22.79)) and anemia (aOR 2.23, 95% CI (1.21, 4.10)), whereas ulcerative colitis patients were more likely to develop post-operative deep vein thrombosis (aOR 9.79, 95% CI (2.41, 39.75)). CD patients were more likely to have perforated ap-pendicitis (aOR 1.37, 95% CI (1.67, 1.11)) and open appendectomy (aOR 1.56, 95% CI (1.96, 1.27)). Conclusions: Appendectomy for appendicitis in IBD patients is associated with adverse hospital outcomes. Focused attempts are needed to decrease the risk of DVT and PE in these patients. Treating patient’s pre-surgical anemia and proactive venous thromboembolism prophylaxis in IBD patients undergoing appendectomy for appendicitis might improve hos-pital outcomes.

1. Overview The Deep Carbon Observatory (DCO) is a ten-year research program to investigate the quantities, movements, forms, and origins of carbon in Earth. More than 90% of Earth’s carbon may reside in the planet’s deep interior, and DCO’s overarching mission is to understand Earth’s entire carbon cycle—beyond the atmosphere, oceans, and shallow crustal environments, which have drawn most previous research attention—to include the deep carbon cycle [1,2]. A decade of focused research has led to major discoveries by DCO scientists on the physical, chemical, and biological roles of carbon in Earth.

Post transplant lymphoproliferative disorder (PTLD) represents a life threatening disorder occurring after transplantation, ranging from a polyclonal mononucleo- sis like illness to a monomorphic high grade neoplasm with cytologic and histopathologic evidence indica- tive of transformation to lymphoma. PTLD of diffuse large B-cell lymphoma (DLBCL) subtype, isolated to the esophagus is a rare diagnosis. We describe the first case of an immunocompromised adult patient diagnosed with DLBCL-PTLD limited to his esophagus without an associated mass or locoregional lymphade-nopathy on imaging since the institution of the revised Cheson criteria, which includes positron emission tomography-computed tomography as the standard staging modality. Even more unique to our case was the suggestion of underlying cytomegalovirus (CMV) gastritis leading to a hypothesis about a less well understood relationship between CMV and Epstein Barr virus (EBV). In the post transplant setting, im- munocompromised state, or EBV positive state, upper gastrointestinal symptoms should prompt investigation with an upper endoscopy (EGD). Additionally, specific to our case, the fact that the patients' presentation was suspicious for CMV gastritis raises the possibility that the CMV infection predated his PTLD increasing his risk of acquiring PTLD. This reemphasizes the im- portance and diagnostic utility of early screening with EGD in patients after transplantation.

Background: Duodenoscope-related multidrug-resistant organism(MDRO) infections raise concerns. Disposable duodenoscopes have been recently introduced in the market and approved by regulatory agencies with the aim to reduce the risk of endoscopic retrograde cholangiopancreatography(ERCP) associated infections. The aim of this study was to evaluate the outcome of procedures performed with single-use duodenoscopes in patients with clinical indications to single-operator cholangiopancreatoscopy. Methods: This is a multicenter international, retrospective study combining all patients who underwent complex biliopancreatic interventions using the combination of a single-use duodenoscope and a single-use cholangioscope. The primary outcome was technical success defined as ERCP completion for the intended clinical indication. Secondary outcomes were procedural duration, rate of cross-over to reusable duodenoscope, operator-reported satisfaction score(1 to 10) on performance rating of the single-use duodenoscope, and adverse event(AE) rate. Results: A total of 66 patients(26, 39.4% female) were included in the study. ERCP was categorized according to ASGE ERCP grading system as 47(71.2%) grade 3 and 19(28.8%) grade 4. The technical success rate was 98.5%(65/66). Procedural duration was 64(interquartile range 15-189) min, cross-over rate to reusable duodenoscope was 1/66(1.5%). The satisfaction score of the single-use duodenoscope classified by the operators was 8.6 ± 1.3 points. Four patients(6.1%) experienced AEs not directly related to the single-use duodenoscope, namely 2 post-ERCP pancreatitis(PEP), 1 cholangitis and 1 ***: Single-use duodenoscope is effective, reliable and safe even in technically challenging procedures with a non-inferiority to reusable duodenoscope, making these devices a viable alternative to standard reusable equipment.

Marked elevations of B-type natriuretic peptide （BNP） are not generally seen in patients with heart failure and preserved ejection fraction （HFpEF）. The objective of this study was to examine the clinical and laboratory characteristics of a large cohort of patients with HFpEF and markedly elevated BNP. A retrospective examination of 421 inpatients at a university hospital admitted with a diagnosis of HFpEF was performed. Clinical and echocardiographic data in 4 groups of patients with levels of BNP ≤ 100 pg/mL, 100-400 pg/mL, 400-1,000 pg/mL and 〉 1,000 pg/mL were compared. Patients with HFpEF and BNP 〉 1,000 pg/mL （28% of the population） were characterized by impaired renal function and greater use of anti-hypertensive medications. A subset of these patients with BNP 〉 1,000 pg/mL had normal renal function （21%） and were significantly older, more frequently female, and tended to have lower ejection fractions. Conversely, patients with HFpEF and BNP ≤100 pg/mL were younger and had preserved renal function. BNP was inversely related to the likelihood of subsequent admission for heart failure, but not to myocardial infarction or death. In conclusion： BNP 〉 1,000 pg/mL is seen in almost 1/3 of patients hospitalized with HFpEF. This elevation of BNP often reflects impaired renal function, but can also be seen in patients with preserved renal function but relatively impaired systolic function.

Extrarenal fibromuscular dysplasia causing gastro- intestinal bleeding without other manifestations and especially sparing renal vasculature is uncommon. The diagnosis of this entity is usually made by radiographic appearance and the treatment is controversial. To our knowledge only seven cases of visceral fibromuscular dysplasia as a primary manifestation of the disease have been described, symptoms range from abdominal pain to gangrene. This is the first case of visceral fibromuscular dysplasia presenting with otherwise asymptomatic gastrointestinal bleeding, without bowel necrosis or ischemic changes. We provide a review of the literature.
