Background: Rare and nutritionally complex diseases, like chronic intestinal failure (CIF), are not encountered regularly by clinicians. Specialized centers with experience in intestinal failure are relatively sparse, leading many patients to rely on local clinicians. Previously published reports demonstrated lack of knowledge in intestinal failure among gastroenterologists in the United States, in Europe, and in the United Kingdom. This study aims to evaluate intestinal failure knowledge in a cohort of registered dietitians.
Methods: A validated, 20-question survey on CIF knowledge covering four key domains was sent to dietitian members of the American Society for Parenteral and Enteral Nutrition. Descriptive data were collected regarding respondents' clinical practice characteristics. Performance was evaluated, and results were compared between self-identified experts and nonexperts in CIF and parenteral nutrition.
Results: Of 94 respondents, 34% self-identified as experts in intestinal failure and 53% in parenteral nutrition management. Most self-identified intestinal failure experts (81.3%) reported managing 11-20 patients with CIF annually, but less than half worked with a multidisciplinary team, and less than one-quarter practiced in an intestinal rehabilitation program. Overall median score was 13.0 (IQR 11.0-15.0). Self-identified dietitians reporting expertise in intestinal failure and parenteral nutrition scored 15 (IQR 12-17) and 14 (IQR 12-17), respectively.
Conclusion: Regardless of self-reported level of expertise, dietitian knowledge scores were high for home parenteral nutrition monitoring and complications of CIF. Given the integral role nutrition plays in intestinal failure, dietitians should be involved in the management of patients with CIF.

Background: Triacylglycerol (TAG) plasma excursions after a high-fat meal are blunted after Roux-en-Y gastric bypass (RYGB), but underlying mechanisms are poorly understood. We studied TAG absorption and metabolism in 12 RYGB-operated individuals and 12 unoperated controls (CON) matched on sex, age, and BMI.
Methods: Participants followed a 7-day controlled diet and on day 4 underwent H-MR Spectroscopy of liver TAG and a high-fat liquid meal with oral and intravenous labeled stable isotope metabolites, subcutaneous abdominal fat biopsies, and indirect calorimetry.

Background: Home parenteral support (PS) is the standard treatment for chronic intestinal failure (CIF) with short bowel syndrome (SBS) as the leading cause. However, outcomes of PS in older patients remain poorly studied.
Methods: This retrospective observational study evaluated patients newly diagnosed with SBS-CIF initiating PS between 2015 and 2020 at a national French CIF referral center.

Cardiac energy metabolic disorder and gut microbiota imbalance: a study on the therapeutic potential of Shenfu Injection in rats with heart failure.

Institute of TCM Diagnosis, Hunan University of Chinese Medicine, Changsha, China.
Objective: To investigate the relationship between heart failure (HF) and gut microbiota-mediated energy metabolism, and to explore the role of Shenfu Injection in this process.
Materials And Methods: In this study, Adriamycin-induced chronic heart failure (CHF) rat model was used and randomly divided into the blank control group (Normal, = 9), HF control group (Model, = 12), Shenfu Injection treatment group (SFI, = 9), and positive drug control group (TMZ, = 9). The changes in gut microbiota structure were analyzed by 16S rRNA high-throughput sequencing, the content of short-chain fatty acids (SCFAs) was detected by targeted metabolomics technology, and cardiac function and energy metabolism-related indicators were evaluated.

Background And Aims: Anorexia of aging is prevalent and constitutes a significant factor in the onset of malnutrition with limited effective interventions. Cannabis-based medicine (CBM) with delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) may have orexigenic properties in older patients with poor appetite. However, current evidence is insufficient regarding the impact of CBM in older patients with poor appetite.
