We report the case of a 62-y-old woman with short bowel syndrome (SBS) and chronic renal failure, successfully treated with teduglutide, who underwent comprehensive systematic nutritional assessment including bioelectrical impedance vectorial analysis (BIVA). The patient did not tolerate the attempt of gradual suspension of parenteral nutrition (PN), bumping into the worsening of nutritional status and renal function. She was declared eligible for teduglutide, a glucagonlike peptide 2 analog that stimulates structural and functional intestinal adaptation and increases nutrient and fluid absorption. ⋯ At 1 y, weight and serum albumin were reduced (-7.5 kg and -0.6 g/dL, respectively); FFM, PhA, and HGS slightly decreased; hydration status and renal function were preserved; and QoL subtly improved. No relevant clinical complications or metabolic imbalances occurred. The inclusion of BIVA in the comprehensive systematic nutritional assessment of SBS patients treated with teduglutide could be proposed for appropriate and safe management, particularly in the presence of renal impairment.

Konjac oligo-glucomannan (KOG) is a non-digestible dietary fiber that is resistant to digestion and absorption in gastrointestinal (GI) tract. Thus, it might be used as an alternative management for constipation. The aim of this study was to evaluate the effects of KOG on gut motility and microbiota to relieve constipation in mice. ⋯ These results suggest that KOG acts as a prebiotic and stimulant laxative for relief and prevention of constipation.

The management of enterocutaneous fistulae (ECF) is complex, challenging, and often associated with metabolic, septic, and nutritional complications. Radiographic quantification of body composition such as fat or lean body mass distribution is a potentially valuable preoperative assessment tool to optimize nutritional status. The aim of this study was to investigate the correlation between total adipose tissue (fat) area (TFA), assessed by computed tomography and magnetic resonance imaging radiology tests, with body weight, body mass index (BMI), various biochemical parameters, need for nutritional support, and survival in patients undergoing ECF repair. ⋯ Abdominal adiposity was strongly correlated with anthropometric parameters at the time of surgery. Earlier identification of patients requiring artificial nutrition at standard preoperative imaging might allow integration of nutritional optimization into initial clinical management plans reducing length of stay and improving clinical outcomes.
