Observational Study
Nutritional intervention in head and neck cancer patients during chemo-radiotherapy.
Head and neck cancer patients experience unintentional weight loss and malnutrition at diagnosis, during oncologic treatment, and after the end of therapy because of reduction of eating ability. The aim of the present study was to assess nutrition intervention efficacy in maintaining basal nutritional conditions. ⋯ To preserve body weight and composition, we identified an energy requirement greater than expected both during and after chemoradiotherapy.

This study developed an instrument in table format to help determine the energy requirements of patients in adverse situations. The instrument allows for the weekly adjustment of nutrition therapy and energy intake, advocating a new approach to treatment based on clinical observation performed by staff specialized in individualized nutrition therapy. ⋯ The proposed nutrition table allows for management of optimal energy and protein intake for patients in different clinical situations, while respecting the different phases of the posttraumatic metabolic response, thus leading to favorable clinical outcomes.

We aimed to evaluate whether long-term treatment with the soluble non-bacterial fraction of kefir affects mean arterial pressure (MAP) and cardiac hypertrophy through the modulation of baroreflex sensitivity, ACE activity, and the inflammatory-to-anti-inflammatory cytokine ratio in spontaneously hypertensive rats (SHRs). ⋯ In summary, our results indicate that long-term administration of the non-bacterial fraction of kefir promotes a significant decrease in both MAP and HR, by improving baroreflex, and reduces cardiac hypertrophy in SHRs, likely via ACE inhibition, and reduction of the TNF-α-to-IL10 ratio.

Recent studies found a low rate of iron deficiency in Bangladeshi non-pregnant and non-lactating women. This was attributed to high iron concentrations in drinking water. However, there are limited data on iron deficiency among pregnant women in Bangladesh. ⋯ This study found a differential prevalence of anemia and iron deficiency among pregnant women living in areas of high and low groundwater iron. Iron status was independently associated with daily iron intake from drinking water. However, a significant proportion of the anemia could not be attributed to iron deficiency. Further research to identify other nutritional and non-nutritional contributors to anemia in Bangladesh is needed to formulate effective prevention and control programs for anemia.

Patients with head and neck cancer have changes in body composition and resting energy expenditure (REE) related to significant inflammatory processes. We investigated REE and body composition in a population of patients with head and neck cancer, comparing the measured REE with predicted energy expenditure and deriving an equation of anthropometric values and body composition. ⋯ Predictive equations, generally recommended by guidelines, are imprecise when compared with IC measures. Therefore, we suggest a new predictive equation.
