Don't give up when communication is difficult: Online well-being advice for caregivers of people with Alzheimer's and dementia.

Sixteen million people in the United States are unpaid caregivers to people with Alzheimer's or dementia. Although caregiver investment is associated with personal and relational benefits, there are also emotional, mental, relational, and physical costs. This study explores online well-being advice for nonprofessional caregivers of people with Alzheimer's and dementia, resulting in 332 online resources that offer informational support for nonprofessional caregivers. Although competent communication directly impacts the well-being of caregiving relationships, only 39 of these texts offered advice related to communication strategies. Thematic analysis of these 39 sources resulted in 1,024 discrete pieces of caregiver advice related to three overarching themes: Daily Routine, Care Recipient Well-Being, and Caregiver Self-Care. We examine the Caregiver Self-Care theme to understand informational support available to caregivers. These self-care advice themes reveal a need for intentional focus on the home health quality of nonprofessional caregivers about ways that communication impacts their everyday lives.

A review of the evidence to support interim reference level for dietary lead exposure in adults.

FDA developed the interim reference level (IRL) for lead of 3 µg/day in children and 12.5 µg/day in women of childbearing age (WOCBA) to better protect the fetus from lead toxicity. These IRLs correspond to a blood lead level (BLL) of 0.5 µg/dL in both populations. The current investigation was performed to determine if the IRL for WOCBA should apply to the general population of adults. A literature review of epidemiological studies was conducted to determine whether a BLL of 0.5 µg/dL is associated with adverse effects in adults. Some studies reported adverse effects over a wide range of BLLs that included 0.5 µg/dL adding uncertainty to conclusions about effects at 0.5 µg/dL; however, no studies clearly identified this BLL as an adverse effect level. Results also showed that the previously developed PTTDI for adults of 75 µg/day lead may not be health protective, supporting use of a lower reference value for lead toxicity in this population group. Use of the 12.5 µg/day IRL as a benchmark for dietary lead intake is one way FDA will ensure that dietary lead intake in adults is reduced.

U.S. Food and Drug Administration's interim reference levels for dietary lead exposure in children and women of childbearing age.

Reducing lead exposure is a public health priority for the US Food and Drug Administration as well as other federal agencies. The goals of this research were to 1) update the maximum daily dietary intake of lead from food, termed an interim reference level (IRL), for children and for women of childbearing age (WOCBA) and 2) to confirm through a literature review that with the exception of neurodevelopment, which was not evaluated here, no adverse effects of lead consistently occur at the blood lead level (BLL) associated with the IRL. Because no safe level of lead exposure has yet been identified for children's health, the IRLs of 3 µg/day for children and 12.5 µg/day for WOCBA were derived from the Centers for Disease Control and Prevention reference value of 5 µg/dL BLL, the level at which public health actions should be initiated. The literature review showed that no adverse effects of lead consistently occurred at the BLL associated with the IRLs (0.5 µg/dL). The IRLs of 3 µg/day for children and 12.5 µg/day for WOCBA should serve as useful benchmarks in evaluating the potential for adverse effects of dietary lead.

Reported Knowledge of Typical Daily Calorie Requirements: Relationship to Demographic Characteristics in US Adults.

BACKGROUND: US obesity rates are at historically high levels, increasing the risk of negative health and economic outcomes at individual and population levels. Findings from earlier studies indicate that many consumers lack a clear understanding of calorie needs, potentially affecting their ability to manage caloric intake. OBJECTIVE: Our aim was to determine the knowledge of typical daily calorie needs of US adults by demographic and other characteristics, using a nationally representative sample. DESIGN: Data were analyzed from 6,267 respondents to the 2007-2008 and 2009-2010 National Health and Nutrition Examination Survey and its supplemental data source, the Flexible Consumer Behavior Survey, to assess reported knowledge of typical daily calorie requirements and associations with demographic and other characteristics of interest. STATISTICAL ANALYSES PERFORMED: Logistic regression for complex sample surveys was used to estimate associations between self-reported daily calorie needs for men and women aged 21 years and older and participant characteristics. RESULTS: Most respondents accurately reported typical daily calorie needs for a person of their sex, age group, and physical activity level, however, distinct differences emerged between demographic groups. Women, non-Hispanic whites, and those with higher income and education levels were more likely to estimate typical daily calorie needs accurately; men were almost four times more likely than women to indicate a lack of knowledge of daily calorie needs. CONCLUSIONS: Knowledge of typical daily calorie requirements is a foundational concept of nutrition literacy. Educational efforts to increase awareness, knowledge, and use of calorie information for certain groups may be helpful to refine interventions and ultimately improve public health in the United States.

Caffeinated energy drinks: adverse event reports to the US Food and Drug Administration and the National Poison Data System, 2008 to 2015.

OBJECTIVE: To describe and compare caffeinated energy drink adverse event (AE) report/exposure call data from the US Food and Drug Administration Center for Food Safety and Applied Nutrition's Adverse Event Reporting System (CAERS) and the American Association of Poison Control Centers' National Poison Data System (NPDS). DESIGN: Cross-sectional. SETTING: Data were evaluated from US-based CAERS reports and NPDS exposure calls, including report/exposure call year, age, sex, location, single v. multiple product consumption, outcome, symptom, intentionality (NPDS only), report type, product name (CAERS only). PARTICIPANTS: The analysis defined participants (cases) by the number of caffeinated energy drink products indicated in each AE report or exposure call. Single product cases included 357 from CAERS and 12 822 from NPDS; multiple product cases included 153 from CAERS and 931 from NPDS. RESULTS: CAERS v. NPDS single product cases were older and more frequently indicated serious symptoms. Multiple v. single product consumers were older in both. In CAERS, unlike NPDS, most multiple product consumers were female. CAERS single v. multiple product reports cited higher proportions of life-threatening events, but less often indicated hospitalization and serious events. NPDS multiple v. single product cases involved fewer ≤5-year-olds and were more often intentional. CONCLUSIONS: Despite limitations, both data sources contribute to post-market surveillance and improve understanding of public health concerns.
