Preoperative Feeding Fortification Among Infants with Congenital Heart Disease is Associated with Higher Growth Velocity in the First 30 Days Post-repair and Lower BMI Percentile for Age at 10 Years: A Retrospective Cohort Study.

It remains unclear how preoperative nutrition fortification impacts postoperative growth trajectories and nutritional status among infants with congenital heart disease. A single center retrospective cohort study was performed to evaluate measures of growth among patients who underwent cardiac repair at 0-18 months of age for atrial septal defect, ventricular septal defect, atrioventricular septal defect, or tetralogy of Fallot. Cohorts were analyzed at 0-30 and 31-60 days post-repair as well as at 2, 5, and 10 years of age. Records of 24 patients who received fortified nutrition and 60 patients who received unfortified nutrition preoperatively were reviewed. Those with fortified nutrition had higher growth velocities in the first 30 days post-repair compared to those with unfortified nutrition: 28.4 (23.8-83.3) grams per day versus 16.7 (7.1-21.4) grams per day, p = 0.004. Weight percentile for age was higher in the unfortified group at 2, 5, and 10 years of age (p = 0.02, p = 0.045, and p = 0.01). Body mass index (BMI) percentile for age was higher in the unfortified group at 5 and 10 years of age (p = 0.045 and p = 0.02) with a trend toward higher prevalence of either overweight or obesity compared to the fortified group (p = 0.13). reoperative nutrition fortification among infants with congenital heart disease is associated with higher growth velocity in the first 30 days post-repair and lower BMI percentile for age at 10 years. Further studies are needed to evaluate the association between preoperative nutrition fortification and postoperative outcomes, nutritional status, and prevalence of obesity in adolescence and adulthood.

Cardiovascular Follow-up of Patients Treated for MIS-C.

OBJECTIVES: To assess the prevalence of residual cardiovascular pathology by cardiac MRI (CMR), ambulatory rhythm monitoring, and cardiopulmonary exercise testing (CPET) in patients ∼6 months after multisystem inflammatory disease in children (MIS-C). METHODS: Patients seen for MIS-C follow-up were referred for CMR, ambulatory rhythm monitoring, and CPET ∼6 months after illness. Patients were included if they had ≥1 follow-up study performed by the time of data collection. MIS-C was diagnosed on the basis of the Centers for Disease Control and Prevention criteria. Myocardial injury during acute illness was defined as serum Troponin-I level >0.05 ng/mL or diminished left ventricular systolic function on echocardiogram. RESULTS: Sixty-nine of 153 patients seen for MIS-C follow-up had ≥1 follow-up cardiac study between October 2020-June 2022. Thirty-seven (54%) had evidence of myocardial injury during acute illness. Of these, 12 of 26 (46%) had ≥1 abnormality on CMR, 4 of 33 (12%) had abnormal ambulatory rhythm monitor results, and 18 of 22 (82%) had reduced functional capacity on CPET. Of the 37 patients without apparent myocardial injury, 11 of 21 (52%) had ≥1 abnormality on CMR, 1 of 24 (4%) had an abnormal ambulatory rhythm monitor result, and 11 of 15 (73%) had reduced functional capacity on CPET. The prevalence of abnormal findings was not statistically significantly different between groups. CONCLUSIONS: The high prevalence of abnormal findings on follow-up cardiac studies and lack of significant difference between patients with and without apparent myocardial injury during hospitalization suggests that all patients treated for MIS-C warrant cardiology follow-up.

Community Practice Implementation of a Self-administered Version of PREMM1,2,6 to Assess Risk for Lynch Syndrome.

BACKGROUND & AIMS: Lynch syndrome is a genetic disorder that greatly increases risk for colorectal and other cancers, although it is underdiagnosed. Prediction of MLH1, MSH2, and MSH6 (PREMM1,2,6) is a web-based tool that analyzes individuals' personal/family histories of cancer to quantify their likelihood of carrying a germline mutation associated with Lynch syndrome. We investigated the feasibility of systematic risk assessment for Lynch syndrome in a community gastroenterology practice using a patient-completed version of PREMM1,2,6. METHODS: PREMM1,2,6 was adapted into a computer tablet version designed for self-administration by patients. Individuals presenting to a community gastroenterology office and endoscopy facility in California completed the PREMM1,2,6 assessment before their visit (n = 3134). The total study duration (8 months) comprised a 2-month initiation period (May 1-June 30, 2013) and a 6-month study period (July 1-December 31, 2013). Genetic counseling and germline analysis for mutations in genes associated with Lynch syndrome (MLH1, MSH2, MSH6, PMS2, and EPCAM) were offered to individuals with PREMM1,2,6 scores of 5% or higher. Patients and providers completed surveys to evaluate the feasibility and satisfaction with the process. RESULTS: Of the 3134 individuals assessed by PREMM1,2,6 during the 6-month study period, 177 individuals (5.6%) had scores of 5% or higher. Of these, 146 individuals underwent genetic testing, along with 28 additional participants recruited nonconsecutively during the initiation period. Mutations associated with Lynch syndrome were detected in 3 of the 146 individuals (2.1%) with PREMM1,2,6 scores of 5% or higher who underwent germline testing, and 3 of the 28 patients (10.7%) recruited during study initiation with PREMM1,2,6 scores of 5% or higher. Of the participants who underwent genetic analysis, 98.6% stated that they understood the information provided to them. All of the surveyed providers stated that they were satisfied with the incorporation of PREMM1,2,6 into their clinical practice, and that they would continue using it to assess risk for Lynch syndrome. CONCLUSIONS: A patient self-administered version of the PREMM1,2,6 Lynch syndrome risk assessment model can be used systematically in community-based gastroenterology and endoscopy practices.

Clipping prevents perforation in large, flat polyps.

AIM: To determine if prophylactic clipping of post-polypectomy endoscopic mucosal resection (EMR) mucosal defects of large, flat, right sided polyps prevents perforations. METHODS: IRB approved review of all colonoscopies, and prospective data collection of grasp and snare EMR performed by 2 endoscopists between January 1, 2010 and March 31, 2014 in a community ambulatory endoscopy center. The study consisted of two phases. In the first phase, all right-sided, flat polyps greater than or equal to 1.2 cm in size were removed using the grasp and snare technique. Clipping was done at the discretion of the endoscopist. In the second phase, all mucosal defects were closed using resolution clips. Phase 2 of the study was powered to detect a statistically significant difference in perforation rate with 148 EMRs, if less than or equal to 2 perforations occurred. RESULTS: In phase 1 of the study, 2121 colonoscopies were performed. Seventy-five patients had 95 large polyps removed. There were 4 perforations in 95 polypectomies (4.2%). The perforations occurred in polyps ranging in size from 1.5 cm to 2.5 cm. In phase 2, there were 2464 colonoscopies performed. One hundred and sixteen patients had 151 large polyps removed, and all mucosal defects were clipped. There were no perforations (P = 0.0016). There were no post-polypectomy hemorrhages in either phase. An average of 2.15 clips were required to close the mucosal defects. The median time to perform the polypectomy and clipping was 13 min, and the median procedure duration was 40 min. Five percent of all patients undergoing colonoscopy in our community based, ambulatory endoscopy center had flat, right sided polyps greater than or equal to 1.2 cm in size. CONCLUSION: Prophylactic clipping of the mucosal resection defect of large, right-sided, flat polyps reduces the incidence of perforation.
