Eating disorders across the life span

Clearly, eating disorders appear in both men and women across the entire life span. Nurses must be aware of eating disorder issues in populations such as children and adolescents, adult men, middle-aged women, and older adults so that proper screening and treatment can occur to reduce the consequences of these potentially life-threatening illnesses.     

Sex-specific effects of interventions that extend fly life span

Genetic and environmental interventions that extend life span are a current focus in research on the biology of aging. Most of this work has focused on differences among genotypes and species. A recent study on fruit flies shows that life span extension because of dietary restriction can be highly sex-specific. Here we review the literature on sex-specific effects of 56 genetic and 41 environmental interventions that extend life span in Drosophila melanogaster. We found that only one-sixth of the experiments provided statistical tests of differences in response between males and females, suggesting that sex-specific effects have been largely ignored. When measured, the life span extension was female-biased in 8 of 16 cases, male-biased in 5 of 16 cases, and not significantly different in only 3 of 16 cases. We discuss possible explanations for the sex-specific differences and suggest various ways in which we might test these hypotheses. We argue that understanding sex differences in the response to life span-extending manipulations should lead to new insights about the basic mechanisms that underlie the biology of aging in both sexes.     

Mental health disaster response: nursing interventions across the life span

In the aftermath of a natural disaster, adult survivors often move through the following phases of disaster response: Heroic Phase, Honeymoon Phase, Disillusionment Phase, and Reconstruction Phase. Understanding age-related responses to traumatic events such as a tornado enables mental health clinicians to individualize appropriate interventions and prevent or diminish emotional sequelae such as post-traumatic stress disorders. Psychiatric-mental health nurses are encouraged to attend local Red Cross disaster training to be prepared should the need arise for mobilization of mental health disaster response teams in your community.     

Comparing violence over the life span in samples of same-sex and opposite-sex cohabitants

Using data from a nationally representative telephone survey that was conducted from November 1995 to May 1996, this study compares lifetime experiences with violent victimization among men and women with a history of same-sex cohabitation and their counterparts with a history of marriage and/or opposite-sex cohabitation only. The study found that respondents who had lived with a same-sex intimate partner were significantly more likely than respondents who had married or lived with an opposite-sex partner only to have been: (a) raped as minors and adults; (b) physically assaulted as children by adult caretakers; and (c) physically assaulted as adults by all types of perpetrators, including intimate partners. The study also confirms previous reports that intimate partner violence is more prevalent among gay male couples than heterosexual couples. However, it contradicts reports that intimate partner violence is more prevalent among lesbian couples than heterosexual couples. Overall study findings suggest that intimate partner violence is perpetrated primarily by men, whether against same-sex or opposite-sex partners.     

Hampering a heartbreaker. Antibiotic might stem injury from heart attack

A TV ad urges people who think they're having a heart attack to pop an aspirin before rushing to the emergency room. They might be even better off taking antibiotics, according to a new study. The work shows that an antibiotic stems a previously untreatable form of heart damage not by killing bugs but by suppressing cellular enzymes.     

Lesbian,gay, and bisexual religiosity across the life span: Associations with group identification and identity salience

This study explores the intersection of sexual and religious identities in lesbian, gay, and bisexual (LGB) individuals by looking at variables associated with religiosity in this community. Ordinary least squares (OLS) regression analysis was used to explore variables that are associated with religiosity in sexual minority individuals. Religious history, connection to the LGB community, and being a person of color were associated with higher levels of religiosity. Feeling that one’s LGB identity is an important part of their identity was associated with lower levels of religiosity. Implications for the LGB community are discussed.
