Background In postoperative Crohn’s disease (POCD), data are lacking on relationships between serum biologic concentrations and treatment outcomes. We assessed if established threshold concentrations of infliximab (IFX), adalimumab (ADA), and ustekinumab (UST) impact outcomes in POCD. Methods Data were extracted from POCD patients with serum biologic concentration measurements using Weill Cornell Medicine biobanks. The primary outcome compared rates of deep remission (achieving both objective [endoscopic or biomarker] and clinical [Harvey-Bradshaw index or Crohn’s Disease Patient Reported Outcome-2] remission), using established serum drug level cutoffs of IFX ≥3 µg/mL, ADA ≥7.5 µg/mL, and UST ≥4.5 µg/mL. Results In 130 patients, median IFX, ADA, and UST concentrations were 10 (interquartile range [IQR], 2.9-26.9) µg/mL, 10.5 (IQR, 4.9-14.9) µg/mL, and 6.9 (IQR, 5.1-10.2) µg/mL, respectively. In patients with IFX ≥3 µg/mL, higher rates of deep remission (39% vs 0%; P = .02) existed compared with those with IFX Conclusions In POCD, established anti-tumor necrosis factor concentrations were associated with improved outcomes. No relationship between UST concentrations and postoperative outcomes existed.

Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare cause of nonthrombotic, noninflammatory ischemic colitis. IMHMV classically presents in men with abdominal pain and bloody diarrhea and is frequently misdiagnosed as inflammatory bowel disease. However, IMHMV causes a more protracted, relapsing course of abdominal pain that does not respond to medical therapy. The diagnosis can be secured by colonoscopic biopsy. Surgical resection is curative and should be considered even in high-risk patients. Here, we describe a case of IMHMV diagnosed preoperatively in a post–liver transplant patient with residual portal hypertension who ultimately underwent successful surgical resection.

The complex nature and comorbidities of patients with non-alcoholic fatty liver disease (NAFLD) highlights the need for a multidisciplinary care model. These multidisciplinary patient-centered models deliver personalized specialty care and improve efficiency and efficacy of therapy. In this paper, we review current models of multidisciplinary care teams and introduce a framework for building a comprehensive NAFLD program based on real-world experience within our institution.

Background In inflammatory bowel disease (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), nonadherence to biologic therapy increases risk of disease flare. The aim of this study was to identify risk factors for nonadherence. Methods This was a single-center retrospective study evaluating patients with IBD treated at a tertiary care center and prescribed self-injectable biologic therapy using the center’s specialty pharmacy. Adherence was defined using medication possession ratio (MPR). Nonadherence was defined as MPR Results Four hundred sixty patients (n = 393 with CD and n = 67 with UC) were evaluated with mean MPR (interquartile range) equaling 0.89 (0.48–1). Overall, 69% of patients were adherent (defined as MPR ≥0.86), 66% of patients with CD and 87% of patients with UC. In univariate analysis, several factors increased risk of nonadherence: CD diagnosis, insurance type, psychiatric history, smoking, prior biologic use, and narcotic use (P < 0.05). In multivariable analysis, Medicaid insurance (odds ratio [OR], 5.5; 95% confidence interval [CI], 1.85–15.6) and CD diagnosis (OR, 2.8; 95% CI, 1.3–6.0) increased risk of nonadherence. In CD, as the number of risk factors increased (narcotic use, psychiatric history, prior biologic use, and smoking), the probability of nonadherence increased. Adherence was 72% in patients with 0–1 risk factors, decreasing to 62%, 61%, and 42% in patients with 2, 3, and 4 risk factors, respectively (P < 0.05). Conclusions This study identified risk factors for nonadherence to biologic therapy. In patients with CD, the probability of nonadherence increased as the number of risk factors increased.

Anatomy is a foundational science mainstay of undergraduate medical school education, particularly in the pre-clerkship curriculum. During the post-clerkship curriculum, students closer to graduate medical education may benefit from a focused concentration on human anatomy related to their specific clinical interests. Here, we describe a course for post-clerkship students that uniquely incorporates a multimodal approach of dissection, didactics, and clinical correlation to radiologic imaging, with the opportunity to personalize student learning on a specialty-specific anatomic region. The course increased students’ confidence of anatomical knowledge and its clinical relevance. Other institutions may benefit from establishing a similar multimodal integrated post-clerkship anatomy curriculum.
