ABSTRACT

INTRODUCTION: malnutrition is a very frequent problem in oncology patients and can have serious repercussions. Adequate nutritional management is cost-effective in terms of health and survival in this population, but it requires multidisciplinary coordination, specific training, and continuous follow-up. OBJECTIVE: to validate the applicability and efficacy of a multidisciplinary nutritional support protocol in oncology patients. METHODS: a multidisciplinary nutritional protocol was developed for oncology patients, with guidelines for screening and assessment of malnutrition, treatment, re-evaluation, and management of side effects, as well as guidance on supplementation and eating patterns. The protocol would be implemented in various clinical centers, collecting data through a structured questionnaire, registering variables before and after implementation. RESULTS: the protocol and its impact were implemented and evaluated in 39 centers. An improvement in nutritional care was observed, evidenced by an earlier initiation of nutritional assessment and an increase in the number of patients receiving adequate care following the protocol implementation. Problems related to inadequate malnutrition coding in the centers, limited resources, and the need for greater interdepartmental collaboration were identified. CONCLUSIONS: the conduct of this study provides insights into how the implementation of a multidisciplinary nutritional support protocol can improve the nutritional care received by patients and informs about the main obstacles to adequate implementation.

ABSTRACT

The aim of this study was to develop a deformable image registration (DIR)-based offline ART protocol capable of identifying significant dosimetric changes in the first treatment fractions to determine when adaptive replanning is needed. A total of 240 images (24 planning CT (pCT) and 216 kilovoltage cone-beam CT (CBCT)) were prospectively acquired from 24 patients with prostate adenocarcinoma during the first three weeks of their treatment (76 Gy in 38 fractions). This set of images was used to plan a hypofractionated virtual treatment (57.3 Gy in 15 fractions); correlation with the DIR of pCT and each CBCT allowed to translate planned doses to each CBCT, and finally mapped back to the pCT to compare with those actually administered. In 37.5% of patients, doses administered in 50% of the rectum (D50) would have exceeded the dose limitation to 50% of the rectum (R50). We first observed a significant variation of the planned rectal volume in the CBCTs of fractions 1, 3, and 5. Then, we found a significant relationship between the D50 accumulated in fractions 1, 3, and 5 and the lack of compliance with the R50. Finally, we found that a D50 variation rate [100 × (administered D50 − planned D50/planned D50)] > 1% in fraction three can reliably identify variations in administered doses that will lead to exceeding rectal dose constraint.

ABSTRACT

INTRODUCTION: Although current recommendations suggest the use of specific formulas in enteral nutrition in people with diabetes, there is little evidence of their long-term effectiveness in glycemic control. The main objective of this study is to evaluate the long-term efficacy (24 weeks) of a specific high-protein hypercaloric enteral nutrition formula for people with diabetes in glycemic control and in their improvement in nutritional status. METHODOLOGY: This was a multicenter, prospective, observational, real-life study of patients with long-term enteral nutrition prescription through gastrostomy or nasogastric tube who received a high protein hypercaloric formula specific for diabetes. Once the participant's informed consent was obtained and the inclusion and exclusion criteria were verified, data relating to glycemic control, inflammation parameters, biochemical data, nutritional status and gastrointestinal tolerance at 0, 12 and 24 weeks were collected. RESULTS: 112 patients were recruited, 44.6% women, age 75.0 (12.0) years and a mean time of evolution of diabetes of 18.1 (9.5) years. The percentage of patients with malnutrition according to VGS decreased throughout the treatment from 78.6% to 29.9% (p < 0.001). Glycemic and HbA1c levels were significantly reduced at 12 and 24 weeks (Blood glucose 155.9-139.0-133.9 mg/dl, p < 0.001; HbA1c 7.7-7.3-7.1%, p < 0.001) while no significant changes were observed in cholesterol, triglycerides, creatinine, or glomerular filtration. A significant increase in variables related to nutritional status was observed: weight, the BMI, albumin, prealbumin and transferrin, and CRP levels were significantly reduced and the CRP/Albumin ratio decreased. Gastrointestinal tolerance was good, the number of patients with moderate-severe symptoms was small, and did not change throughout the follow-up. CONCLUSION: Our real-life study suggests that the use of a specific hyperprotein hypercaloric formula for diabetes during a 6-month nutritional treatment allows adequate glycemic control and nutritional evolution, with good gastrointestinal tolerance.
