Objective: The purpose of the study was to examine calories administered to inpatients over 90 years of age.

Subjects and Methods: The results of nutrition support team (NST) interventions for 294 elderly patients aged 90 years or older who were evaluated at least 4 times over at least 21 days from April 2008 to March 2022 were investigated retrospectively. The Geriatric Nutritional Risk Index (GNRI) was compared at the first and last NST session. The subjects were divided into three groups with an increased (n = 161), unchanged (n = 9), and decreased (n = 124) GNRI. The recommended calories, achievement of these calories, and the nutritional intake at the last session were compared among the groups.

Results: There was no significant difference in the recommended calories among the groups, but the achievement rate and intake differed significantly between cases with increased and decreased GNRI. In these respective groups, the recommended calories were 999.4 and 994.0 kcal, the achievement rates were 99.7% and 88.2% (p < 0.01), and the intakes were 1,003.1 and 879.9 kcal (p < 0.01).

Conclusion: The optimal intake of calories to avoid a risk of decreased nutrition in inpatients aged 90 years or older is suggested to be about 1,000 kcal.

Delayed gastric emptying (DGE) can occur as a complication after pancreaticoduodenectomy, but there are few detailed reports on its effect on clinical course and nutritional status. We examined occurrence of DGE, clinical course, and nutritional status in 175 patients with pancreatic cancer who underwent pancreaticoduodenectomy at our hospital from 2014 to 2017. The patients were divided into those with (n = 98) and without (n = 77) DGE in the postoperative course. Nutritional status was examined based on the CONUT score. DGE was found to be significantly associated with female sex and development of postoperative complications, but not with nutritional status, and there was no association of DGE with life prognosis. These results suggest that DGE is associated with development of postoperative complications, but that with proper nutritional support, a patient with DGE can be discharged without an aggravated nutritional status.

Aim: The goal of the study was to evaluate factors contributing to poor weight gain in hospitalized pediatric patients.

Patients and methods: A retrospective cohort study was performed in 111 pediatric patients. SD values for body weight calculated from the cross-sectional growth chart were used to evaluate physiques. After nutritional factors were adjusted for covariates such as age and treatment, multiple regression analyses (forced entry) were performed using body weight (ΔSD) before and after a nutrition support team (NST) intervention as an outcome.

Results: The mean age at baseline was 8.1 ± 4.4 years. The disease types were hematological malignant tumors (n = 50), solid tumors (n = 30), brain tumors (n = 12), and other diseases (n = 19). The mean period over which the patients underwent NST interventions was 144.5 ± 87.8 days. The mean body weight at baseline (SD) and the change during the intervention (ΔSD) were –0.6 ± 1.4 and 0.03 ± 0.7 kg, respectively. Multiple regression analyses showed that a history of hematopoietic stem cell transplantation was a significant factor in reducing body weight (ΔSD).

Conclusion: This study suggests that patients who are scheduled to receive hematopoietic stem cell transplantation should undergo intensive nutritional intervention soon after their diagnosis.
