Revising primary and secondary school curricula in the Caribbean to enhance education on the risks for noncommunicable diseases.

In the English-speaking Caribbean, an estimated 46% of men and 61% of women are currently overweight or obese, and 8% of children younger than 5 years are also overweight. To combat this worsening epidemic, driven by unhealthy dietary patterns, the Heads of Government of the Caribbean Community (CARICOM) issued the 2007 Port-of-Spain Declaration, which included mandates on the provision of healthy school meals, promotion of healthy dietary patterns, and reintroduction of physical education in schools. These mandates are aligned with evidence-based approaches used in childhood obesity prevention programs.

Effect of passive antibodies derived from rotavirus-like particles on neonatal calf diarrhea caused by rotavirus in an oral challenge model.

Our objective was to evaluate the efficacy of bovine rotavirus antigen-specific passive antibody for reducing the duration of diarrhea induced by oral challenge with bovine rotavirus in a neonatal calf model. The bovine rotavirus-specific passive antibodies were produced before the study by hyperimmunization of pregnant cows during the dry period with an adjuvanted vaccine containing recombinantly-expressed rotavirus virus-like particles. Eighty-three calves were cleanly collected at birth and randomly assigned to 1 of 3 groups as follows: (1) control group that was colostrum deprived and fed milk replacer for first feeding, (2) group that was colostrum deprived and fed milk replacer mixed with antirotavirus antibodies for first feeding, or (3) group that was fed colostrum replacer mixed with antirotavirus antibodies and a product approved by the US Department of Agriculture containing antibodies against Escherichia coli K99 and bovine coronavirus for first feeding.

Effect of rumen-protected branched-chain amino acid supplementation on production- and energy-related metabolites during the first 35 days in milk in Holstein dairy cows.

Essential AA are critical for multiple physiological processes. Branched-chain AA (BCAA) supplementation has beneficial effects on body weight, lipogenesis, and insulin resistance in several species. The BCAA are used for milk and body protein synthesis as well as being oxidized by the tricarboxylic acid cycle to produce ATP during catabolic states.

Consuming Lower-Protein Nutrition Bars with Added Leucine Elicits Postprandial Changes in Appetite Sensations in Healthy Women.

Background: Higher-protein meals (>25 g protein/meal) have been associated with enhanced satiety but the role of amino acids is unclear. Leucine has been proposed to stimulate satiety in rodents but has not been assessed in humans.

Objective: We assessed the acute effects of lower-protein nutrition bars, enhanced with a leucine peptide (LP), on postprandial appetite sensations in combination with plasma leucine and peptide YY (PYY) in healthy women.
