Cell therapy to repair broken hearts

Current therapeutic options for myocardial infarction include medical therapy, of proven but limited benefit, and various surgical options, which have either restricted applicability or unproven benefit. New cellular-based therapeutic strategies are being developed in response to the shortcomings of available treatments. These include attempts to reinitiate cardiomyocyte proliferation in the adult, conversion of fibroblasts to contractile myocytes and transplantation of myocytes into injured myocardium. The development and current status of these techniques and their relative advantages, problems remaining to be solved and potential clinical applications are reviewed.

Cost-benefit analysis of walking to prevent coronary heart disease

OBJECTIVE: To quantify the cost-benefit relationship of walking to prevent coronary heart disease. DESIGN: Cost-benefit analysis. PARTICIPANTS: Hypothetical cohorts of sedentary men and women aged 35 to 74 years. MAIN OUTCOME MEASURES: Decision-analysis simulation was used to evaluate the cost-benefit relationship of walking, varying level of benefit from exercise, frequency of exercise to achieve benefit, participation rates, and costs of exercise and injury. RESULTS: At a relative risk of 1.9 for heart disease associated with sedentary behavior, $5.6 billion would be saved annually if 10% of adults began a regular walking program. A $4.3 billion savings is predicted if the entire sedentary population began walking regularly and the cost of the time an individual spends exercising is accounted for in those who dislike exercising. According to our baseline assumptions, walking is economically beneficial for men aged 35 to 64 years and for women aged 55 to 64 years. The threshold of relative risk at which economic benefit is found for walking in this population overall is estimated at 1.7, and under a volunteer model, most adults would benefit even at a relative risk of 1.15. CONCLUSIONS: There are significant sex and age differences in the economic benefits of walking to prevent heart disease. The value assigned to the time an individual spends exercising has a significant impact on the results. Overall, a substantial savings is predicted from encouraging sedentary individuals to participate in a regular walking program.     

Effect of grade retention in first grade on psychosocial outcomes.

In a 4-year longitudinal study, the authors investigated effects of retention in first grade on children's externalizing and internalizing behaviors; social acceptance; and behavioral, cognitive, and affective engagement. From a large multiethnic sample (n = 784) of children below the median on literacy at school entrance, 124 retained children were matched with 251 promoted children on the basis of propensity scores (probability of being retained in first grade estimated from 72 baseline variables). Relative to promoted children, retained children were found to benefit from retention in both the short and longer terms with respect to decreased teacher-rated hyperactivity, decreased peer-rated sadness and withdrawal, and increased teacher-rated behavioral engagement. Retained children had a short-term increase in mean peer-rated liking and school belongingness relative to promoted children, but this advantage showed a substantial decrease in the longer term. Retention had a positive short-term effect on children's perceived school belonging and a positive longer term effect on perceived academic self-efficacy. Retention may bestow advantages in the short-term, but longer term detrimental effects on social acceptance may lead to the documented longer term negative effects of retention.

Who helps whom in older parent-child families

While previous research has assumed that older persons who live with adult children do so because of their poverty or disability, some recent evidence suggests that many of these extended households primarily benefit the child. This article attempts to provide a better understanding of the relative contributions of parents and adult children who live together through detailed analysis of data from the Survey of Income and Program Participation (SIPP). We find unmarried children tend to benefit more from and contribute less to extended households than married children. Similarly, unmarried parents benefit more from living with children than married parents. Results of logistic regression show that financial need and need for assistance with activities of daily living wre important determinants of coresidence for both unmarried children and unmarried parents. Controlling need, racial and ethnic minorities were more likely to live in extended families than non-Hispanic Whites.
