wikipedia on the “five components of frailty” mentioned below: “Frailty is determined based on cutoffs in 5 components – Muscle weakness, weight loss, low physical activity, exhaustion, and slow walking speed.”

jules levin, NATAP: JCEM editorial on testosterone/estradiol & bone loss (0110)

NATAP: Testosterone/estradiol & Bone Loss

“Although previous studies in men had shown that serum estradiol levels were related to bone density (4) and that estrogen regulated bone turnover (5, 6) and bone loss (7) in elderly men, more recent studies have now also demonstrated that serum estradiol, and not serum testosterone, levels are the most robust hormonal predictors of fracture risk in aging men (8, 9, 10). What is perhaps somewhat surprising from the study of Burnett-Bowie et al. (2) is that relatively small reductions in estradiol levels appear to significantly modulate rates of bone loss. Although this may reflect just how heavily leveraged the male skeleton is on circulating estrogen levels, an alternate explanation for this finding is that changes in serum estradiol levels may not fully reflect reductions in local estrogen production in osteoblastic cells (11), and the extent of skeletal estrogen deficiency induced by anastrozole may therefore be underestimated by serum estradiol measurements.”

“The findings of Burnett-Bowie et al. (2) also need to be placed in the context of previous trials of testosterone replacement in older men. Thus, Amory et al. (12) found that 200 mg of im testosterone every 2 wk increased spine BMD by 10% and total hip BMD by 3%. By contrast, effects of transdermal testosterone on bone density have been marginal (13), suggesting that the higher testosterone levels associated with im treatment may be necessary for achieving beneficial skeletal effects. Based on the evidence provided by Burnett-Bowie et al. (2), it is probable that it is the higher estradiol levels associated with the higher testosterone levels (rather than the testosterone levels themselves) that are necessary for optimal skeletal benefits.”

AIDS and Older Persons: Studies of the Impact in Thailand and Cambodia

Two teams of US researchers have worked in colaboration with Thai and Cambodian researchers to study the impact of AIDS on older persons in Thailand and Cambodia. Data collection for Thailand spans 1998-2009; data collection in Cambodia spans 2004-2007. Funding has been provided by the U.S. National Institute on Aging. The projects utilize a multi-method approach and aim to provide a comprehensive assessment of a wide range of impacts on older persons, especially parents of those who die, and their implications for understanding the impact on older persons in other settings.

Additional Information

HIV/AIDS is usually viewed as a disease affecting reproductive-age adults and their infant children. Discussions rarely consider the impact on older persons and, when they do, they typically focus on those who are infected themselves. Not only can older adults contract HIV themselves but a far greater number of older persons are affected through the infection of significant others, especially their adult children. The pathways through which they are affected include caregiving, coresidence and providing financial and material support during the illness, paying funeral expenses, fostering orphaned grandchildren, losing current and old-age support that the child would have provide, and suffering grief and emotional stress. These in turn can have profound consequences for their economic, social, psychological, and physical well-being. At the same time, by playing a major role in caregiving, older persons make significant contributions to the well-being of their infected sons and daughters and, by assuming the role of foster parents, to the grandchildren who are left behind.
