The indications and contraindications of parenteral nutrition (PN) are discussed in view of recent clinical findings. For decades, PN has been restricted to patients unable to tolerate enteral nutrition (EN) intake owing to the perceived risk of severe side-effects. The evolution of the PN substrate composition and delivery of nutrition via all-in-one bags has dramatically improved the application prospects of PN. Recent studies show similar complication rates of nutrition therapy administered through enteral and intravenous routes. Therefore, indications of PN have, based on evidence, extended beyond complete gastrointestinal (GI) failure to include conditions such as insufficient EN generating persistent negative energy balance and insufficient protein intakes, malabsorption, or specific needs that are impossible to cover with EN feeds.

Objective: To analyze the clinical characteristics and available treatment strategies for reoperation of neonatal high jejunal atresia, and recommend preventive measures to reduce the reoperation rate of high jejunal atresia.
Methods: The clinical data of 16 children with high jejunal atresia who underwent reoperation in the Neonatal Surgery Department at Children's Hospital of Zhejiang University School of Medicine from January 2018 to January 2023 were retrospectively analyzed.
Results: Among the 16 unplanned reoperations, 7 (43.

This study presents a documented case of catheter-related bloodstream infection caused by in a 60-year-old female receiving home parenteral nutrition. Despite presenting with only minor clinical symptoms, blood cultures from both central and peripheral sites confirmed the presence of , identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and whole-genome sequencing.

Clin Nutr ESPEN
January 2025
Intestinal Failure Unit, Salford Royal NHS Foundation Trust, Salford M6 8HD, UK; School of Health Sciences, University of Manchester, Manchester M13 9PL, UK.
Background & Aims: Current estimates of the prevalence of iron deficiency anaemia (IDA) in patients with chronic intestinal failure (CIF) exceed those seen in general population, however, the studies to-date are limited with relatively small numbers of patients. The aim of the study was to determine the point prevalence of IDA in a large cohort of stable HPN-dependent adults managed by a specialist Intestinal Failure Unit.
Methods: This was a retrospective cohort study of HPN-dependent adults managed by a national UK IF Reference Centre between 01/01/2019 and 31/12/2019.
Thiamine Deficiency Is Common and Underrecognized in Emergency Department Oncology Patients.
J Clin Med
January 2025
Department of Emergency Medicine, Henry Ford Health, Detroit, MI 48202, USA.
: Wernicke's encephalopathy can occur in oncology patients independent of alcohol use, likely resulting from poor dietary thiamine intake. High metabolic demands, such as those in acute illnesses seen in the emergency department (ED), can exacerbate thiamine deficiency. In this study, our objective was to assess the incidence of thiamine deficiency in ED oncology patients, which could lead to Wernicke's encephalopathy or other thiamine deficiency disorders if left untreated.
