Background/aim: This study aimed to compare dietary intake (DI) after gastrectomy for gastric cancer between patients with (C group) and without (NC group) postoperative surgical complications.

Patients And Methods: This prospective observational study enrolled patients who underwent gastrectomy for gastric cancer. DI was assessed using a food frequency questionnaire with 82 food items (FFQW82) during nutritional counseling before surgery and at one and three months after surgery.

Results: A total of 225 patients participated in this study. Of the 225 patients, 193 had no postoperative complications, and 32 had postoperative complications (Clavien-Dindo grade ≥2). The median DI at 1 month postoperatively was 1508 kcal/day in the NC group and 1,470.5 kcal/day in the C group (p=0.175). The median DI at 3 months postoperatively was 1,623 kcal/day in the NC group and 1575 kcal/day in the C group (p=0.473). There was a significant difference between the NC and C groups in the rate of decrease in DI at one month (median: -8.44% vs. -15.37%, p=0.032) and at three months postoperatively (median: -3.58% vs. -6.12%, p=0.038).

Conclusion: There was a statistically significant difference in the rate of decrease in DI after gastrectomy between the C and NC groups at 1 and 3 months postoperatively. Our results suggest that patients with postoperative surgical complications require additional nutritional treatment for decreased DI.

Objectives: The relationship between sugar-sweetened beverage (SSB) intake and phenotypic age acceleration (PhenoAgeAccel) is unclear. The aim of this study was to explore the associations between the energy and timing of SSB intake and PhenoAgeAccel in adults.

Methods: A cross-sectional analysis was conducted using data from the National Health and Nutrition Examination Survey (NHANES) 2007-2010, which involved U.

Background: Nutritional status in childhood is associated with a number of short- and long-term health effects. The rising prevalence of childhood obesity highlights the necessity of understanding dietary patterns in children. The study provides an assessment of energy and macronutrient intake and food categories' contribution to energy intake in Croatian primary school children, according to BMI status.

The impact of a tailored nutrition intervention delivered for the duration of hospitalisation on daily energy delivery for patients with critical illness (INTENT): a phase II randomised controlled trial.

Crit Care

January 2025

Australian and New Zealand Intensive Care Research Centre, School of Public Health and Preventive Medicine, Department of Epidemiology and Preventative Medicine, Monash University, 553 St Kilda Road, Melbourne, VIC, Australia.

Background: Nutrition interventions commenced in ICU and continued through to hospital discharge have not been definitively tested in critical care to date. To commence a program of research, we aimed to determine if a tailored nutrition intervention delivered for the duration of hospitalisation delivers more energy than usual care to patients initially admitted to the Intensive Care Unit (ICU).

Methods: A multicentre, unblinded, parallel-group, phase II trial was conducted in twenty-two hospitals in Australia and New Zealand.

Article Synopsis
  • The study investigated how insulin sensitivity, insulin response to glucose, and diet affect fat loss and energy expenditure in African American women with obesity.
  • 69 women were assigned to either a low-fat or low-carbohydrate diet for 10 weeks, with measures of body composition and energy expenditure taken before and after.
  • Results showed that those on a low-CHO diet lost more fat and experienced less decline in energy expenditure than those on a low-fat diet, suggesting low-CHO diets may be more effective for fat loss in this group.

Introduction: Very low-calorie diets with hospitalization have demonstrated promise as a viable therapeutic option for severe obesity and its associated comorbidities. However, large studies providing a comprehensive longitudinal observation of patients undergoing this therapy are lacking. We evaluated the effectiveness of treating severe obesity in hospitalized patients, using very low-calorie diets and clinical support to develop lifestyle changes.
