Effects of including a palmitic acid-enriched supplement in low and high starch diets on milk production and energy partitioning of primiparous and multiparous dairy cows between mid and late-lactation.

The aim of our study was to assess the effects of low or high-starch diets with or without palmitic acid (C16:0) supplementation on the yield of milk, milk components, and energy partitioning of primiparous and multiparous dairy cows between mid and late-lactation. Thirty-two Holstein cows, 12 primiparous ([mean ± SD] 163 ± 33 d in milk) and 20 multiparous ([mean ± SD] 179 ± 37 d in milk), were used in a split-plot Latin square design. Parity was considered the main plot, and within each plot, treatments were then randomly assigned in a replicated 4 × 4 Latin square with 21 d periods and balanced for carryover effects.

Public Health.

Background: Malnutrition is a condition associated with negative outcomes in elderly patients, such as loss of functionality and mortality. The cause of malnutrition is multifactorial: secondary to changes in eating habits, dysphagia and loss of interest in food. It is a frequent condition in patients with advanced dementia.

Public Health.

Background: Emerging evidence suggests that air pollution exposure might diminish the cognitive health of older adults. Although many studies have reported that air pollution is associated with increased dementia risk, associations with the process of cognitive decline have been more heterogeneous.

Method: We used biennial data between 2000 to 2016 from respondents>65 years in the Health and Retirement Study (HRS), a national, population-based cohort in the United States, to study associations of air pollution with cognitive decline.

Public Health.

Background: Frailty syndrome is a prevalent condition associated with high-impact outcomes for the elderly, such as falls, hospitalization, functional loss and mortality. It can be triggered by several clinical conditions and dementia is one of them. More studies are needed to deeply understand the relationship between these two conditions.
