The Changing Roles of Grandparents Raising Grandchildren

The 2000 U.S. Census reported there were 158.9 million people ages 30 and older living in households in the United States, of whom 5.8 million (or 3.6%) were co-resident grandparents, defined as living with grandchildren younger than 18. Among these findings, 2.4 million (42%) were also grandparent caregivers. It is estimated that 1 in 10 grandparents will be the primary caregiver for at least 6 months for a grandchild before the child's eighteenth birthday. This article will discuss some of the challenges and hardships that these grandparents are faced with while raising their grandchildren. In addition, some attention to practice and policy are looked at to provide assistance to grandparents and kinship that may be raising relatives. There will be financial burden, worry, health issues, and freedom restrictions for this population. Many of these families may not be aware of programs, services, and resources that are available to them.     

Migration,Poverty, and Risk of HIV Infection: An Application of Social Capital Theory

A majority of current HIV/AIDS interventions are designed primarily after individual-based public health models and pay little attention to the socioeconomic environment in which HIV transmission occurs. This article focuses on outlining how migration acts as a conduit for disease transmission in South Africa and then proposes a macro-level prevention model based on social capital theory, thus then supplementing current prevention literature. It is based on the argument that social disruption and stresses from migration lead to sexual interactions during the migration periods that amplify the risk of HIV transmission among migrants.     

Weapons of penile smooth muscle destruction: Androgen deficiency promotes accumulation of adipocytes in the corpus cavernosum

In men with erectile dysfunction, venous leakage is a common condition among non-responders to medical management and is attributed to penile smooth muscle atrophy. Androgens play a role in regulating trabecular smooth muscle growth and function. Further, androgens stimulate differentiation of progenitor cells into smooth muscle cells and inhibit their differentiation into adipocytes. We postulate that androgens exert a direct effect on penile tissue to maintain erectile function, and that androgen deficiency produces metabolic and structural imbalances in the corpus cavernosum, resulting in venous leakage and erectile dysfunction. To date, research efforts on the mechanisms by which androgens regulate penile erectile physiology have mainly focused on investigating the role of the NO/cGMP pathway. However, androgen-dependent mechanisms that regulate tissue remodeling have been poorly defined. Characterization of the molecular and cellular mechanisms by which androgens regulate corpus cavernosum structural and functional integrity would provide significant gains in knowledge and understanding of an important pathogenic process. In this review, we discuss the potential role of androgen in maintaining differentiation of progenitor cells into smooth muscle lineage and inhibition of differentiation into adipocytes. Androgen deficiency promotes differentiation into adipogenic lineage, and accumulation of adipocytes in the corpus cavernosum may contribute to erectile dysfunction.

A Two-Question Method for Assessing Gender Categories in the Social and Medical Sciences

Three studies (N = 990) assessed the statistical reliability of two methods of determining gender identity that can capture transgender spectrum identities (i.e., current gender identities different from birth-assigned gender categories). Study 1 evaluated a single question with four response options (female, male, transgender, other) on university students. The missing data rate was higher than the valid response rates for transgender and other options using this method. Study 2 evaluated a method of asking two separate questions (i.e., one for current identity and another for birth-assigned category), with response options specific to each. Results showed no missing data and two times the transgender spectrum response rate compared to Study 1. Study 3 showed that the two-question method also worked in community samples, producing near-zero missing data. The two-question method also identified cisgender identities (same birth-assigned and current gender identity), making it a dynamic and desirable measurement tool for the social and medical sciences.
