The disposable soma theory suggests that longevity is determined through the setting of longevity assurance mechanisms so as to provide an optimal compromise between investments in somatic maintenance (including stress resistance) and in reproduction. A corollary is that species with low extrinsic mortality are predicted to invest relatively more effort in maintenance, resulting in slower intrinsic ageing, than species with high extrinsic mortality.

Inquiry: A Journal of Medical Care Organization, Provision and Financing

Catholic hospitals maintain a significant presence in delivering hospital services in the United States, but little is known about the ways they differ from other ownership forms in similar market environments. This paper analyzes characteristics of Catholic, other private nonprofit, and investor-owned hospitals in metropolitan areas of the United States to identify the extent to which Catholic hospitals differ from other ownership types on three dimensions of mission-driven identity--access, stigmatized, and compassionate care services.

This paper applies instrumental variable (IV) techniques and estimates the average benefits of invasive surgical treatments for marginal acute myocardial infarction (AMI) patients by insurance coverage. The study uses data from the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project (HCUP), State Inpatient Databases for the state of Washington, for years 1988-1993. We observed differences in average benefits for marginal patients across insurance subpopulations that cannot be explained by differences in measured clinical circumstances.

OBJECTIVE: The objective of this study was to examine the relationship between private dentists' attitudes toward Medicaid and Medicaid patients and their extent of Medicaid participation. METHODS: A survey was mailed to all Medicaid dentists in Alabama in 2003 (N = 518). Descriptive statistics were calculated, and multiple regression models were tested. The "dentists' extent of participation" was a measure of the percentage of Medicaid patients seen in one month.

The support for the elderly is facing big challenges with the problem of population aging. Transfers from adult children could partly insure elderly parents against low income and high medical expenditure. There are two main motives for transfers in the literature, namely altruism and exchange. By using data from a new household survey of people aged 45?years and above in China, we estimate the transfer derivatives with the adjustment of medical expenditure in elderly parents' income.

BACKGROUND: Incarcerated women share a disproportionate burden of mental illness. Although psychotropic medications are available to women in prison, adjunctive treatment modalities, such as Iyengar yoga, may increase psychological well-being.

A growing body of research investigates the possible relationships between religion and mental health. After developing a series of arguments linking various aspects of religion with anxiety and tranquility, we test relevant hypotheses using data from the 1996 Genera Social Survey. Results show that frequency of religious attendance and the belief in an afterlife are inversely associated with feelings of anxiety and positively associated with feelings of tranquility. However, frequency of prayer has no direct association with either outcome.

Drug-drug interactions at transporters present a significant and under-investigated clinical problem. Investigations of specific transporter functions and screening for potential drug-drug interactions, both in vitro and especially in vivo, will require validated experimental probes. Fexofenadine, an approved, well-tolerated drug, is a promising probe for studies of membrane transporter function. Although fexofenadine pharmacokinetics are known to be controlled by transporters, the contributions of individual transporters have not been defined.
