Optimization of nutrition support practices early after hematopoietic cell transplantation.

Nutrition support is often required during hematopoietic cell transplant (HCT) given the gastrointestinal toxicity that frequently precludes adequate protein-calorie intake. This article reviews the latest evidence for enteral versus parenteral nutrition in the adult and pediatric HCT population and addresses key considerations as well as barriers to implement this in practice. Registered Dietitian Nutritionists are key members of the interdisciplinary team to proactively manage enteral nutrition support to provide timely, adequate protein and calories to help prevent malnutrition, loss of lean body mass, and functional decline as well as provide evidence-based diet recommendations. This article also reviews emerging research supporting the role of luminal nutrients to maintain microbiotal diversity.

Helping Patients Eat Better During and Beyond Cancer Treatment: Continued Nutrition Management Throughout Care to Address Diet, Malnutrition, and Obesity in Cancer.

Cancer patients and survivors are at risk of poor clinical outcomes due to poor nutritional intake following cancer diagnosis. During cancer treatment, treatment toxicities can affect eating patterns and can lead to malnutrition resulting in loss of lean body mass and excessive weight loss. Following treatment and throughout survivorship, patients are at risk of not meeting national nutrition guidelines for cancer survivors, which can affect recurrence and survival. Obesity, which is highly prevalent in cancer patients and survivors, can affect clinical outcomes during treatment by masking malnutrition and is also a risk factor for cancer recurrence and poorer survival in some cancers. Appropriate and effective nutritional education and guidance by trained clinicians are needed throughout the cancer continuum. This article presents an overview of recommendations and guidelines for nutrition and weight management and provides recent examples of behavioral theory-based targeted lifestyle interventions designed to increase adherence to recommendation by cancer patients and survivors.

Metabolic syndrome appears early after hematopoietic cell transplantation.

BACKGROUND: Improved survival after allogeneic hematopoietic cell transplantation (allo-HCT) enables us to learn more about potential late complications after HCT, one of which is metabolic syndrome. There are no studies investigating the prevalence or development of metabolic syndrome within the first year post-HCT in adult myeloablative transplant recipients. METHODS: In this retrospective study, we evaluated the prevalence of and risk factors associated with metabolic syndrome early post-HCT in human subjects. Due to lack of complete information regarding all the factors that define metabolic syndrome, we evaluated metabolic characteristics using available objective data referred to as modified metabolic syndrome (MMS). The cohort included 785 patients. RESULTS: We demonstrated that the incidence of MMS was 34% pre-HCT, 48% at day 80 post-HCT, and 40% at 1 year post-HCT. MMS at day 80 post-HCT was predictive of having MMS at 1 year post-HCT. CONCLUSION: These results support the need for nutrition and lifestyle intervention to prevent and treat metabolic abnormalities among patients who survive the acute transplant period.
