Stein, PhD 918 GALE ENCYCLOPEDIA OF GENETIC DISORDERS Phenotype see Genotypes and phenotypes Nerve cells have specialized extensions called dendrites and axons. Stimulating a nerve cell triggers nerve impulses, or signals, that speed down the axon. These nerve impulses then stimulate the end of an axon to release chemicals called neurotransmitters that spread IPhenylketonuria out and communicate with the dendrites of neighboring nerve cells. Definition Many nerve cells have long, wire-like axons that are Phenylketonuria (PKU) can be defined as a rare covered by an insulating layer called the myelin sheath. PKU is the most serious form of a class of nine levels in the blood and brain can produce nerve cells diseases referred to as “hyperphenylalaninemia,” all of with abnormal axons and dendrites, and cause imperfec- which involve above normal (elevated) levels of pheny- tions in the myelin sheath referred to as hypomyelination lalanine in the blood.

    Despite these findings discount 7.5mg mobic overnight delivery, the spiritual needs of patients are often ignored or not 8 buy 7.5mg mobic visa,9 15 mg mobic amex,13 satisfied (Mayo Patient Expectations Survey, unpublished data, 1994). Nevertheless, clinician interest in patient spirituality has increased because of a growing number of studies that have shown an association between increased religious involvement and 14 spirituality and better health outcomes. This chapter reviews the results of published studies, meta-analyses, systematic reviews and subject reviews that have examined the association between religious involvement, patient spirituality and spiritual interventions (e. Finally, suggestions on how clinicians might ethically assess and support the spiritual needs of patients are provided. Furthermore, intercessory prayer studies have significant methodological flaws, making their relevance to clinicians 15,16 unclear. USE OF RELIGIOUS AND SPIRITUAL VARIABLES IN MEDICAL RESEARCH Religious and spiritual variables are not widely used in medical research. For example, a 17 review of 2348 studies published in four major psychiatry journals between 1978 and 1982 revealed that only 59 (2. Neglect of religious and spiritual variables in medical research may be attributable, in part, to the reliance on the biomedical model in which physical evidence is paramount. While the biomedical model is excellent for describing certain disease mechanisms (e. Religious involvement, spirituality and medicine 225 Of the studies that have considered the effects of religious or spiritual factors on health, most have used measures of religious involvement (e. The main reason for this practice is the greater consensus on how to define and measure religious involvement as opposed to spirituality. RELIGIOUS INVOLVEMENT, SPIRITUALITY AND PHYSICAL HEALTH A majority of the nearly 350 studies of physical health that used religious and spiritual variables have found that religious involvement and spirituality are associated with better 25 physical health outcomes. Mortality During the past three decades, at least 18 prospective studies have shown that religiously 26–43 involved persons live longer. The populations examined in these studies included not only entire communities but also specific groups. The religious and spiritual variables 29,31,34 used in these studies included membership in a religious congregation, attendance 26–28,30,32,33,35,36,38–42 37 at religious Services, living within a religious community and self- 43 44 reported religiosity. One study of hospitalized veterans, however, found no relationship between religious involvement, religious coping and mortality. In addition, a 45 2-year longitudinal cohort study of nearly 600 patients aged 55 years or older found that religious struggle with illness (e. Recent prospective studies have carefully controlled for potential confounding 46 38 variables. A 28-year study of 5286 adults (aged 21–65 years) found that frequent (once per week or more) attenders of religious services were 23% less likely than non- attenders to die during the follow-up period (relative hazard 0. Notably, this study also found that mobilityimpaired persons were more likely to be frequent attenders than non- 39 attenders. A 5-year study examined the same relationship in 1931 adults (aged 55 years or older). Frequent attenders were 24% less likely to die than nonattenders during the follow-up period (relative hazard 0. A 6-year study examined the same relationship in 3968 adults (aged 65 years or older). Frequent attenders were 28% less likely than infrequent (less than once per week) to die during the follow-up period (relative hazard 0. Finally, a 9-year study of a nationally representative sample of 22080 American adults (aged 20 years or older) found the risk of death for non-attenders to be 1. Complementary therapies in neurology 226 47 A recent meta-analysis of 42 studies of nearly 126000 persons found that highly religious persons had a 29% higher odds of survival compared with less religious persons (odds ratio (OR) 1.

Cardiovascular disease Studies have found that religious involvement is associated with less cardiovascular 48 disease.
