Development of a Culinary Medicine Curriculum to Support Nutrition Knowledge for Gastroenterology Fellows and Faculty.

Gastroenterologists encounter many nutrition-related disorders in their practice, yet the nutritional needs of patients with chronic gastrointestinal (GI) and liver disease are largely unaddressed by treating physicians, due to suboptimal nutrition education. To address this gap, we developed and piloted a culinary medicine course for a GI fellowship training program. The objective of this study is to describe the development, implementation, and acceptability of the course. A registered dietitian, a chef instructor, and a gastroenterology clinical professor trained in culinary medicine developed the four-class tailored curriculum and delivered the classes remotely. Each class had a theme related to commonly encountered GI disorders and included hands-on meal preparation, a nutrition lecture, and a patient case study discussion. Post-course feedback surveys were disseminated. Twenty-three GI physicians enrolled in the course and the attendance rates in classes 1-4 were 83%, 65%, 61%, and 48%, respectively. Among 15 completed feedback surveys, 80% reported that the class contents were either moderately or extremely useful and all endorsed the curriculum for other gastroenterologists. Future studies of culinary medicine programs tailored to medical specialties should identify strategies to maintain engagement and assess the impact on nutrition knowledge, competencies, and translation of these new skills to clinical practice.

Incidence, determinants and outcomes of pregnancy-associated hepatitis B flares: A regional hospital-based cohort study.

BACKGROUND & AIMS: There is limited knowledge about hepatitis B virus (HBV) flare among pregnant women. We evaluated the incidence, determinants and outcomes of HBV flare in a multicultural cohort of pregnant HBV-infected women in the United States. METHODS: We performed a retrospective cohort study of pregnant hepatitis B surface antigen-positive women cared for at hospital-based clinics of 4 medical centres in Southeastern Pennsylvania from 2006 to 2015. The main outcome was incident HBV flare (alanine aminotransferase [ALT] ≥2 times upper limit of normal) during pregnancy or within 6 months after delivery. Among patients with flare, we determined development of jaundice (total bilirubin ≥2.5 mg/dL) and hepatic decompensation. Multivariable logistic regression was used to estimate odds ratios (ORs) of HBV flare for risk factors of interest, including timing of flare (during pregnancy versus post-delivery), nulliparity, younger age, HBV e antigen (HBeAg) status, and lack of anti-HBV therapy. RESULTS: Among 310 pregnant predominantly African HBV-infected women with 388 pregnancies, the incidence of HBV flare was 14% (95% CI, 10-18%) during pregnancy and 16% (95% CI, 11-24%) post-delivery. Jaundice developed in 12% and hepatic decompensation in 2%. Positive HBeAg was associated with HBV flare (OR, 2.55; 95% CI, 1.04-6.20). HBV DNA was measured in 55% of patients, and only 50% were referred for HBV specialty care. CONCLUSIONS: Pregnancy-associated hepatitis B flare occurred in 14% during pregnancy and 16% post-delivery and rarely led to hepatic decompensation. Positive HBeAg was the main risk factor identified. Women did not have adequate HBV monitoring or follow-up during pregnancy.

Long-term outcomes of palliative colonic stenting versus emergency surgery for acute proximal malignant colonic obstruction: a multicenter trial.

Background and study aims Long-term data are limited regarding clinical outcomes of self-expanding metal stents as an alternative for surgery in the treatment of acute proximal MBO. The aim of this study was to compare the long-term outcomes of stenting to surgery for palliation in patients with incurable obstructive CRC for lesions proximal to the splenic flexure. Patients and methods Retrospective multicenter cohort study of obstructing proximal CRC patients with who underwent insertion of a SEMS (n = 69) or surgery (n = 36) from 1999 to 2014. The primary endpoint was relief of obstruction. Secondary endpoints included technical success, duration of hospital stay, early and late adverse events (AEs) and survival. Results Technical success was achieved in 62/69 (89.8 %) patients in the SEMS group and in 36 /36 (100 %) patients who underwent surgery (P = 0.09). In the SEMS group, 10 patients underwent stenting as a bridge to surgery and 59 underwent stent placement for palliation. Clinical relief was achieved in 78 % of patients with stenting and in 100 % of patients who underwent surgery (P < 0.001). Patients with SEMS had significantly less acute AEs compared to the surgery group (7.2 % vs. 30.5 %, P = 0.003). Hospital mortality for the SEMS group was 0 % compared to 5.6 % in the surgery group (P = 0.11). Patients in the SEMS group had a significantly shorter median hospital stay (4 days) as compared to the surgery group (8 days) (P < 0.01). Maintenance of decompression without the recurrence of bowel obstruction until death or last follow-up was lower in the SEMS group (73.9 %) than the surgery group (97.3 %; P = 0.003). SEMS placement was associated with higher long-term complication rates compared to surgery (21 % and 11 % P = 0.27). Late SEMS AEs included occlusion (10 %), migration (5 %), and colonic ulcer (6 %). At 120 weeks, survival in the SEMS group was 5.6 % vs. 0 % in the surgery group (P = 0.8). Conclusions Technical and clinical success associated with proximal colonic obstruction are higher with surgery when compared to SEMS, but surgery is associated with longer hospital stays and more early AEs. SEMS should be considered the initial mode of therapy in patients with acute proximal MBO and surgery should be reserved for SEMS failure, as surgery involves a high morbidity and mortality.

Esophageal stent fixation with endoscopic suturing device improves clinical outcomes and reduces complications in patients with locally advanced esophageal cancer prior to neoadjuvant therapy: a large multicenter experience.

BACKGROUND: Endoscopic placement of fully covered self-expanding metal stents (FCSEMS) to treat malignant dysphagia in patients with esophageal cancer significantly improves dysphagia; however, these stents have a high migration rate. AIM: To determine whether FCSEMS fixation using an endoscopic suturing device treated malignant dysphagia and prevented stent migration in patients with locally advanced esophageal cancer receiving neoadjuvant therapy when compared to patients with FCSEMS placement alone. METHOD: A review of patients with locally advanced esophageal cancer who underwent FCSEMS placement at 3 centers was performed. Patients were divided into two groups: Group A (n = 26) was composed of patients who underwent FCSEMS placement with suture placement, and Group B (n = 67) was composed of patients with FCSEMS placement alone. RESULTS: There were no significant differences between Groups A and B in demographics, and tumor characteristics. The technical success rate for stent placement was 100 %. There was no difference between Groups A and B in the median stent diameter and stent lengths. Mean dysphagia score obtained at 1 week after stent placement had improved significantly from baseline (2.4 and 1, respectively, p < 0.001). Patients had a median follow-up of 4 months. Immediate adverse events were mild chest discomfort in 4 patients in Group A and 2 patients in Group B (p = 0.05), and significant acid reflux in 3 patient in Group A compared to 2 patients in Group B (p = 0.1). The stent migration rate was significantly lower in Group A compared to compared to Group B (7.7 vs 26.9 %, respectively, p = 0.004). There was a delayed perforation in 1 patient and 1 death due to aspiration pneumonia in Group B. CONCLUSION: Fixation of esophageal FCSEMSs by using an endoscopic suturing device in patients receiving neoadjuvant therapy was shown to be feasible, safe, and relatively effective at preventing stent migration compared to those who had stent placed alone.

A large multicenter study of recurrence after surgical resection of branch-duct intraductal papillary mucinous neoplasm of the pancreas.

BACKGROUND: Surgery for pancreatic branch-duct intraductal papillary mucinous neoplasm (BD-IPMN) is indicated for therapy of symptomatic patients and to prevent development of invasive cancer. There is currently no consensus on management of BD-IPMN patients after surgical resection. The aim of this retrospective multicenter study was to determine the recurrence and long-term survival after surgical resection of BD-IPMN and to determine the predictive factors of recurrence. METHODS: All patients who underwent surgery for BD-IPMN from 2005 to 2011 at 2 centers were identified. The diagnosis of BD-IPMN was based upon imaging and endosonographic analysis, and was confirmed by pathological analysis. The lesions were classified into 4 categories according to the WHO classification. Data on cyst characteristics, operative procedure, recurrence, and follow-up were evaluated. Recurrence was defined as the presence of BD-IPMN or mass in the remnant pancreas after surgery as seen on follow-up imaging. Recurrence suspected on imaging was confirmed via histological analysis when possible. RESULTS: A number of 271 patients (67% female; mean age 63.4 yrs) with BD-IPMN underwent surgical resection. The mean size of the cyst was 24.2mm (range, 12-80). There were 34 (12.5%) patients with an associated mass. 82 (30.3%) patients had worrisome features in the cyst on pre-operative EUS, included mural nodules (N.=25), solid component (N.=27), debris (N.=25), and a dilated major pancreatic duct (N.=5). 144(53%) patients had a pancreaticoduodenectomy for head lesions, 125 (46%) had distal pancreatectomy for tail/body lesions, and 1 (1%) underwent a total pancreatectomy. Histology showed 86% with noninvasive IPMN (adenoma 31%, moderate dysplasia 24%, severe dysplasia or carcinoma in situ 31%) and 14% with invasive IPMN. The mean patient follow-up was 28 months (range, 10-180 months). Recurrence in the remnant pancreas occurred in 34 (12.5%) patients. Of the patients with recurrence, 3/34 had invasive carcinoma and 31/34 had noninvasive cystic lesions; all patients with invasive carcinoma recurrence were those with a previous invasive IPMN. On MVA, risk factors for cyst recurrence were severe dysplasia/intraductal carcinoma in situ and invasive IPMN even after adjusting for elevated CEA (>193 ng/mL), type of surgery, and cyst size (OR 2.8, 95% CI=1.1-7.3; P=0.028). 3 patients who had invasive IPMN and 1 who had severe dysplasia patient with recurrence died, all because of recurrent cancer, with the mean time from recurrence to death being 36 months. CONCLUSIONS: The risk of BD-IPMN recurrence after resection depends upon the histological type, with the highest-risk groups being those with severe dysplasia/intraductal carcinoma in situ and invasive IPMN. Even after negative resection margins, the pancreatic remnant still harbors a risk of recurrence which requires long-term surveillance.
