Malnutrition is frequent among older adults, especially those living in nursing homes, but the association between residential setting and nutritional status is controversial. The aim of this study was to examine the association between living setting (nursing home versus community) and malnutrition while adjusting for demographic, socioeconomic, health-related, and psychosocial factors. ⋯ Risk of malnutrition and malnutrition are more prevalent among nursing home residents than community dwellers. Physical (functional status) and mental health (symptoms of depression and loneliness) seems more relevant to nutritional status than residential setting by itself. These findings should be taken into account when designing public health policies to tackle malnutrition among older adults.

Randomized Controlled Trial
Change of some oxidative stress parameters after supplementation with whey protein isolate in patients with type 2 diabetes.
The aim of this study was to evaluate the effects of undenatured whey protein isolate (WPI; ≥92.5%) with a high content of native cysteine (2.7%) and a standardized content of lactoferrin (≥0.7%) on parameters related to oxidative stress and inflammation in individuals with type 2 diabetes mellitus. ⋯ Supplementation with WPI may be useful in patients with diabetes to control fasting glycemia. Moreover, it can help to improve inflammatory and oxidative stress, which play a crucial role in the development of diabetes complications and also in the progression of other chronic diseases.

Sarcopenia promotes worsening of nutritional status and an increase in comorbidities. Likewise, use of validated instruments to assess nutritional and comorbidity factors are warranted. Thus, the objectives were to assess the prevalence of risk for sarcopenia and to determine whether there is an association between sarcopenia and nutritional status and comorbidities in hospitalized patients with cancer. ⋯ In the present study, ∼40% of patients with cancer had a risk for sarcopenia and a greater prediction for nutritional risk (49%) and comorbidities (29%).

Chumlea's formulas are a way of predicting height from knee height (KHt), including among individuals >60 y of age who cannot stand upright. However, the formulas were developed with white and African American people and have not yet been validated in native Africans >60 y of age. The aims of the study were to assess Chumlea's formulas in older people in central Africa and to propose a new validated formula for the same population. ⋯ Chumlea's formulas provided a poor estimate of height in this population sample. The proposed formula more accurately estimates height in older native Africans. This formula should be tested in other sub-Saharan African countries to extend its use in clinical practice and in future studies.
