1. Number of Very Elderly Beginning Dialysis Increased Greatly in Last Decade But Only 46 Percent Were Alive One Year Later
The number of octogenarians (people aged 80 to 89) and nonagenarians (people 90 to 99) who began dialysis increased from 7,054 people in 1996 to 13,577 people in 2003, according to a new study (Article, p. 177).
Overall, one year survival rates for patients on dialysis did not materially change from 1996 to 2003, remaining at about 50 percent. Survival rates for these very elderly are substantially lower than those previously reported.
Researchers used data from a large national kidney data system. Risk for death was strongly associated with older age, inability to walk (nonambulatory status) and the number of chronic conditions a person had.benefits of chin ups
2. Sleep Apnea Can Be Diagnosed Without Overnights in a Sleep Lab
Exclusively ambulatory techniques and equipment were as successful at identifying and treating sleep apnea as the current method of polysomnography, which requires several supervised overnight stays in a sleep laboratory (Article, p. Both groups received continuous positive airway pressure at night at home through a CPAP machine with face mask and hose.
After three months, the groups had the same results on three outcome measures, and those who received the initial diagnosis at home were more likely to adhere to the use of the CPAP treatment.
