University of New Mexico, MSC05 3040, 1 University of New Mexico, Albuquerque, NM 87131-0001.

Published: September 2017

Background: Overweight and obese body mass index (BMI) status affects an increasing number of children in the United States. The school setting has been identified as a focus area to implement obesity prevention programs.

Methods: A database search of PubMed, Education Search Complete, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) was conducted for peer-reviewed articles published between January 2005 and December 2015 pertaining to programs offered in the school setting to grades K-12 in the United States with a nutrition education component and measured BMI percentile or BMI z-score as an outcome.

Results: Seven studies focused on elementary (K-5) populations and 2 studies focused on grades 6-8. Among the 9 identified studies, those with long-term (greater than 1 year) implementation showed more pronounced results with positive impact on reducing overweight/obese BMI measures.

Conclusions: This set of studies suggests that long-term nutrition education delivered in the school setting can provide children with tools to attain a healthy weight status. Additional studies examining participants' BMI status years after the initial study, and studies examining programs in grades 9-12 are needed to determine the most effective delivery time and methods.

Preoperative Nutritional Status Influences Enteral Nutrition Weaning 6 Months Post-Surgery in Patients with Esophageal Cancer.

Asian Pac J Cancer Prev

January 2025

Department of Anesthesiology and Resuscitology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, Okayama, Japan.

Objective: This study aimed to clarify whether nutritional status at admission affects enteral nutrition weaning 6 months after surgery in patients with esophageal cancer.

Methods: This was a retrospective study of 81 patients who underwent subtotal esophageal cancer resection between April 2014 and February 2016. The survey items were as follows: 1) sex, 2) age, 3) presence or absence of family members living together, 4) clinical stage, 5) surgical procedure, 6) reconstructed organs, 7) nutritional status at admission, 8) presence or absence of postoperative complications (anastomotic leakage, chylothorax, and recurrent laryngeal nerve paralysis), and 9) presence or absence of treatment other than surgery (chemo- or radiotherapy).

Background: Protein-energy wasting (PEW), a unique weight loss linked to nutritional and metabolic abnormalities, is common in patients undergoing hemodialysis (HD) and associated with adverse outcomes. This study investigated whether extended-hours HD combined with a liberalized diet could overcome PEW and improve survival.

Methods: The body mass index (BMI) and survival outcomes in patients undergoing extended-hours HD were evaluated for up to 8 years using data from the LIBeralized diet Extended-houRs hemodialysis Therapy (LIBERTY) cohort.

Background: There are numerous articles, book chapters, and published guidelines on the topic of clinical ethics in the use of artificially administered nutrition and hydration, which often incorporates end-of-life (EOL) nutrition care and support. Components of clinical ethics involve the importance of ethical principles, patient-centered care, and shared decision-making. However, there is sparse information on how to educate patients and caregivers on this subject.

PrP Glycoprotein Is Indispensable for Maintenance of Skeletal Muscle Homeostasis During Aging.

J Cachexia Sarcopenia Muscle

February 2025

Department of Bioactive Material Sciences, Research Center of Bioactive Materials, Jeonbuk National University, Jeonju, Republic of Korea.

Background: The cellular prion protein (PrP), a glycoprotein encoded by the PRNP gene, is known to modulate muscle mass and exercise capacity. However, the role of PrP in the maintenance and regeneration of skeletal muscle during ageing remains unclear.

Methods: This study investigated the change in PrP expression during muscle formation using C2C12 cells and evaluated muscle function in Prnp wild-type (WT) and knock-out (KO) mice at different ages (1, 9 and 15 months).
