Effectiveness of a grief intervention for caregivers of people with dementia

In this article, we report on the structure and effectiveness of a grief management coaching intervention with caregivers of individuals with dementia. The intervention was informed by Marwit and Meuser’s Caregiver Grief Model and considered levels of grief, sense of empowerment, coping, and resilience using five methods of delivery. Results indicate that the intervention had significant positive effects on caregivers’ levels of grief and increased their levels of empowerment, coping, and resilience. The intervention was found to be effective across caregivers’ characteristics as well as across five delivery modalities. Through description of this intervention, as well as outcome, this research contributes to the body of knowledge about caregivers’ disenfranchised grief and ways to effectively address it

Evidence for dynamic rearrangements but lack of fate or position restrictions in premigratory avian trunk neural crest

Neural crest (NC) cells emerge from the dorsal trunk neural tube (NT) and migrate ventrally to colonize neuronal derivatives, as well as dorsolaterally to form melanocytes. Here, we test whether different dorsoventral levels in the NT have similar or differential ability to contribute to NC cells and their derivatives. To this end, we precisely labeled NT precursors at specific dorsoventral levels of the chick NT using fluorescent dyes and a photoconvertible fluorescent protein. NT and NC cell dynamics were then examined in vivo and in slice culture using two-photon and confocal time-lapse imaging. The results show that NC precursors undergo dynamic rearrangements within the neuroepithelium, yielding an overall ventral to dorsal movement toward the midline of the NT, where they exit in a stochastic manner to populate multiple derivatives. No differences were noted in the ability of precursors from different dorsoventral levels of the NT to contribute to NC derivatives, with the exception of sympathetic ganglia, which appeared to be ‘filled’ by the first population to emigrate. Rather than restricted developmental potential, however, this is probably due to a matter of timing

Substitution of Fish for Red Meat or Poultry and Risk of Ischemic Stroke

We investigated the risk of ischemic stroke and its subtypes when red meat or poultry was substituted with fish. A total of 57,053 participants aged 50⁻65 years at baseline were included in the Danish Diet, Cancer and Health study. All participants filled in a food-frequency questionnaire at recruitment. Potential ischemic stroke cases were identified by linkage to the Danish National Patient Register, and all cases were validated and subclassified. Substitutions were investigated as 150 g/week of fish for 150 g/week of red meat or of poultry using multivariable Cox proportional hazard regression models. During 13.5 years of follow-up, 1879 participants developed an ischemic stroke. Replacing red meat or poultry with fish was not associated with the rate of total ischemic stroke, but there was a statistically significant lower rate of large artery atherosclerosis when fish replaced processed (hazard ratio (HR): 0.78; 95% confidence interval (CI): 0.67; 0.90) and unprocessed (HR: 0.87; 95% CI: 0.75; 0.99) red meat. A statistically significant higher rate of cardioembolism was found when poultry was replaced by total fish (HR: 1.42; 95% CI: 1.04; 1.93). When fatty fish replaced unprocessed red meat, a statistically significant lower rate of small-vessel occlusion was found (HR: 0.88; 95% CI: 0.77; 0.99). In conclusion, replacing red meat with fish was not associated with risk of total ischemic stroke but was associated with a lower risk of subtypes of ischemic stroke

Preventing Violence in Seven Countries: Global Convergence in Policies

Do governments take the measures that are supported by the best scientific evidence available? We present a brief review of the situation in: Australia, Canada, Germany, the Netherlands, Spain, the United Kingdom, and the United States. Our findings show surprisingly similar developments across countries. While all seven countries are moving towards evidence-based decision making regarding policies and programs to prevent violence, there remain a number of difficulties before this end can be achieved. For example, there continue to be few randomized controlled trials or rigorous quasi-experimental studies on aggression and violence. Results from experimental research are essential to both policy makers and researchers to determine the effectiveness of programs as well as increase our knowledge of the problem. Additionally, all noted that media attention for violence is high in their country, often leading to management by crisis with the result that policies are not based on evidence, but instead seek to appease public outrage. And perhaps because of attendant organizational problems (i.e., in many countries violence prevention was not under the guise of one particular agency or ministry), most have not developed a coordinated policy focusing on the prevention of violence and physical aggression. It is hypothesized that leaders in democratic countries, who must run for election every 4 to 6 years, may feel a need to focus on short-term planning rather than long-term preventive policies since the costs, but not the benefits for the latter would be incurred while they still served in office. We also noted a general absence of expertise beyond those within scientific circles. The need for these ideas to be more widely accepted will be an essential ingredient to real and sustaining change. This means that there must be better communication and increased understanding between researchers and policy makers. Toward those ends, the recent establishment of the Campbell Collaboration, formed to provide international systematic reviews of program effectiveness, will make these results more available and accessible to politicians, administrators and those charged with making key policy decision

Local Meat Brands Attract Consumer Demand

Research has shown that good value for money is the top attribute driving consumers to choose one meat product over another from among the products on retail shelves (Wolf and Thulin, 2000). The aim of this research was to determine how consumers define “local,” examine whether local is an important driver of meat purchase decisions, and profile local consumers. The Food, Conservation, and Energy Act of 2008 defines as local any product that is transported less than 400 miles from its place of origin (Martinez et. al, 2010), but consumers define local differently. Adams and Adams (2011) found local to be less than 100 miles from the home, while the Hartman Group (2008) indicated less than 100 miles was considered to be local, followed by within the consumer’s state. To examine local meat attitudes, this research conducted personal interviews in San Luis Obispo County in 2012 among 290 meat consumers. Respondents rated the desirability of seven features of meat. Fifty-two percent of respondents indicated a local brand is an extremely or very desirable meat characteristic and were therefore identified as local meat consumers. The local meat consumers were more likely to be Baby Boomer females who purchased meat in locally owned retail markets. They spent more in a typical month on meat, particularly beef, making them a valuable market segment. Local consumers rate good value as their top attribute, which is tied with local. What does local mean to consumers? Sixty-nine percent of respondents indicated that local meant more to them than mileage. Eighty-one percent of meat purchasers defined local to be grown and/or raised within their city or county. When respondents were asked to define local in a sense of mileage, almost 75% said grown and/or raised less than 50 miles from home. When asked to rate the importance of local food products, consumers rated fresh fruits and fresh vegetables as very important. Local meats were somewhat to very important and local wines were somewhat important. This research shows that local brands are important to a large consumer group. It is recommended that retail food outlets include local products on their shelves and identify them based on geographic area rather than mileage

Marine n-3 Polyunsaturated Fatty Acids and the Risk of Ischemic Stroke

Background and Purpose- We hypothesized that total marine n-3 polyunsaturated fatty acids (PUFA), in particular eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in the diet and in adipose tissue (biomarkers of long-term intake and endogenous exposure) were inversely associated with the risk of ischemic stroke and its subtypes. Methods- The Diet, Cancer and Health cohort consisted of 57 053 participants aged 50 to 65 years at enrolment. All participants filled in a food frequency questionnaire and had an adipose tissue biopsy taken at baseline. Information on ischemic stroke during follow-up was obtained from The Danish National Patient Register, and all cases were validated. Cases and a random sample of 3203 subjects from the whole cohort had their fatty acid composition of adipose tissue determined by gas chromatography. Results- During 13.5 years of follow-up 1879 participants developed an ischemic stroke. Adipose tissue content of EPA was inversely associated with total ischemic stroke (hazard ratio [HR], 0.74; 95% CI, 0.62-0.88) when comparing the highest with the lowest quartile. Also, lower rates of large artery atherosclerosis were seen with higher intakes of total marine n-3 PUFA (HR, 0.69; 95% CI, 0.50-0.95), EPA (HR, 0.66; 95% CI, 0.48-0.91) and DHA (HR, 0.72; 95% CI, 0.53-0.99), and higher adipose tissue content of EPA (HR, 0.52; 95% CI, 0.36-0.76). Higher rates of cardioembolism were seen with higher intakes of total marine n-3 PUFA (HR, 2.50; 95% CI, 1.38-4.53) and DHA (HR, 2.12; 95% CI, 1.21-3.69) as well as with higher adipose tissue content of total marine n-3 PUFA (HR, 2.63; 95% CI, 1.33-5.19) and DHA (HR, 2.00; 95% CI, 1.04-3.84). The EPA content in adipose tissue was inversely associated with small-vessel occlusion (HR, 0.69; 95% CI, 0.55-0.88). Conclusions- EPA was associated with lower risks of most types of ischemic stroke, apart from cardioembolism, while inconsistent findings were observed for total marine n-3 PUFA and DHA
