RESUMEN

Studies have assessed omega-3 fatty acids and cognitive decline among older adults and cognitive development among children, although less is known about cognitive or neurological effects among young adults. We examined whether omega-3 supplementation from krill oil could improve cognition and resilience among young military officers compared to a control. This double-blind, placebo-controlled trial enrolled 555 officers (mean age 23.4 ± 2.8, 98.6% male) entering the United States (US) Army Infantry Basic Officer Leaders Course (IBOLC) with the intention to complete the US Ranger Course. Volunteer participants consumed eight dietary supplements daily of krill oil containing 2.3 g omega-3 or control (macadamia nut oil) over an approximate 20-week period. Cognitive functioning, resilience, and mood were assessed during a well-rested period at approximately 14 weeks and after a battlefield simulation at 16 weeks. Blood spot samples were collected to monitor compliance and dietary intake was assessed. All hypotheses were tested using both 'Intention to Treat' (ITT) and 'As Per Protocol' (APP) approaches. Of the 555 randomized individuals, 245 (44.1%) completed the study. No statistically significant group-by-time interactions indicating treatment effect were found on any outcomes. Poor compliance was indicated by lower than expected omega-3 elevations in the treatment group, and may have contributed to a failure to detect a response.

RESUMEN

The United States (US) Food and Drug Administration has updated the Daily Values (DVs) for the Nutrition Facts Label on packaged foods. We used the National Health and Nutrition Examination Survey 2009-2012 data with the International Life Sciences Institute, North America Fortification Database, which identifies intrinsic, mandatory enriched, and fortified sources of nutrients in foods and beverages, to model the new DVs' potential impact on adult (≥19 years of age) intake. We assumed that manufacturers will adjust voluntary fortification to maintain percent DV claims. We assessed the percent of the US population whose usual intake (UI) was < the Estimated Average Requirement (EAR), and ≥ the Upper Limit (UL) based on the current DVs, and modeled estimated UI and %

RESUMEN

BACKGROUND: Nutrients are added to the diet through fortification/enrichment and dietary supplements (DSs). Meeting the US Dietary Reference Intakes (DRIs) varies by nutrient and population subsegments. OBJECTIVE: The aim of this study was to assess the relative role of naturally occurring, enriched/fortified, and DS sources of 15 micronutrients with reference to the DRIs. METHODS: We used the NHANES 2009-2012 (≥2 y old, n = 16,975) data, the ILSI North America Fortification database, and the National Cancer Institute usual intake method. RESULTS: Prevalence of nutrient intake from naturally occurring sources below the Estimated Average Requirement (EAR) varied from 5% for vitamin B-12 to 100% for vitamin D, with ≥40% of the population below the EAR for 8 of the 14 nutrients (ages ≥2 y). With enrichment/fortification, the percentage below the EAR decreased to the following for vitamins A (35%), C (34%), and B-6 (7%), folate (8%), thiamin (5%), riboflavin (3%), niacin (1%), and iron (2%). Nutrients from DSs further improved intakes related to the EAR for 12 nutrients (ages ≥2 y). For 9-18-y-olds, the percentages of nutrient intakes below the EAR were 14-50% higher than for 2-8-y-olds. The Tolerable Upper Intake Level (UL) was exceeded among children aged 2-8 y for folate (41.7%), niacin (10.1%), and zinc (39.9%), whereas among ages ≥2 y and 9-18 y no prevalence of intakes over the UL exceeded 10%. CONCLUSIONS: Fortification/enrichment constitutes a meaningful contribution to reducing the percentage of individuals with less than the EAR for their demographic. These data underscore the need to encourage better dietary patterns to improve the intake of nutrients at risk of low intake.

RESUMEN

Intake of nutrients fundamental for optimal neuronal function is of increasing interest. The potential importance of omega-3 highly unsaturated fatty acids (HUFAs) for optimizing emotional states, cognitive function, and mental health has been demonstrated in observational studies and randomized controlled trials. Omega-3 (HUFAs), specifically EPA (eicosapentaenoic acid) and docosahexaenoic acid (DHA), are concentrated in neural tissues and are essential for neural function, normative neurodevelopment, neurotransmitter, and neural immune functions. Omega-3 HUFAs must be obtained from the diet, predominantly from marine sources such as fish and other seafood. HUFAs also can be found in a variety of dietary supplements (omega-3 fatty acid esters, fish oil and krill oil). As dietary supplements, omega-3 HUFAs (fatty acid esters, fish and krill oils) differ substantially in their physicochemical properties and nutrient content. Here we present the design and methods for the Ranger Resilience and Improved Performance on Phospholipid bound Omega-3's (RRIPP-3) study. RRIPP-3 was a double blind, randomized, controlled trial among individuals in the United States (US) Army Infantry Basic Officer Leaders Course (IBOLC) and following US Ranger School training (RC) at Fort Benning, GA of omega-3 HUFA on krill oil versus placebo supplementation. The RRIPP-3 study sought to determine if krill oil supplementation with omega-3 HUFAs supports aspects of cognitive functioning critical to battlefield success when measured immediately after an intense combat simulation. Sub-analyses addressed basic improvements in IBOLC performance. We also describe additional outcome measures critical for interpretation of the study results, such as diet and other dietary supplement use.

RESUMEN

In the United States (U.S.), food fortification and/or enrichment and dietary supplement (DS) use impacts nutrient intakes. Our aim was to examine race/ethnicity and income (Poverty Income Ratio, PIR) differences in meeting the Dietary Reference Intakes based on estimated dietary intakes among the U.S. population age ≥2 years (n = 16,975). Two 24-hour recalls from the National Health and Nutrition Examination Survey (NHANES) cycles 2009-2012 were used to estimate the intake of 15 nutrients as naturally occurring, enriched/fortified, and plus DSs. Across racial/ethnic groups and within PIR categories, significant differences were observed in the %< Estimated Average Requirement (EAR) for vitamin A following enrichment/fortification (E/F) and for vitamin B12 and riboflavin following both E/F and DS use when comparing non-Hispanic blacks, Hispanics, and the other race/ethnicity group to non-Hispanic whites. The %

RESUMEN

Epilepsy is a common childhood neurologic disorder. In 2007, epilepsy affected an estimated 450,000 children aged 0-17 years in the United States. Approximately 53% of children with epilepsy and special health care needs have co-occurring conditions, and only about one third have access to comprehensive care. The few studies of mortality risk among children with epilepsy as compared with the general population generally find a higher risk for death among children with epilepsy with co-occurring conditions but a similar risk for death among children with epilepsy with no co-occurring conditions. However, samples from these mortality studies are often small, limiting comparisons, and are not representative. This highlights the need for expanded mortality surveillance among children with epilepsy to better understand their excess mortality. This report describes mortality among children with epilepsy in South Carolina during 2000-2011 by demographic characteristics and underlying causes of death. The overall mortality rate among children with epilepsy was 8.8 deaths per 1,000 person-years, and the annual risk for death was 0.84%. Developmental conditions, cardiovascular disorders, and injuries were the most common causes of death among children with epilepsy. Team-based care coordination across medical and nonmedical systems can improve outcomes and reduce health care costs for children with special health care needs, but they require more study among children with epilepsy. Ensuring appropriate and timely health care and social services for children with epilepsy, especially those with complications, might reduce the risk for premature death. Health care providers, social service providers, advocacy groups and others can work together to assess whether coordinated care can improve outcomes for children with epilepsy.
