Blogs Comment On Health Care Reform Legislation, Congressional Funding For D.C., Other Topics
The following summarizes selected women"s health-related blog entries.~ "Just the Facts, Sir: The False Dichotomy of Catholics vs. "Pro-Choice" on Common Ground," Jodi Jacobson, RH Reality Check: In anticipation of the release of the White House"s "common ground" proposal to reduce the need for abortion and help prevent unintended pregnancies, "numerous members of the male pontificator commentariat are trying to spark anxiety by claiming Obama will have to make a choice between "the Catholic vote" and "the pro-choice community,"" Jacobson writes. However, "[n]othing could be further from the truth," she states, noting that Obama received the majority of the Catholic vote in the election and that a "majority of Catholic voters approve of [his] performance to date." There is "no danger" of Obama losing Catholic support "on this particular issue, as long as the administration makes clear its values and principles and goals and objectives, and as long as it sticks to the facts," Jacobson continues. She lists several steps that the White House should take with its proposal, including making it clear that the administration is "committed to evidence-based policies in public health" and that "the best way to reduce unintended pregnancies, and hence the need for abortion, is to provide universal access to prevention services." By focusing on evidence-based public health policies, the Obama administration "can, in the long run, actually bring profound change to this debate," Jacobson writes. She concludes that "evidence-based policies put into practice will achieve many of the goals we seek and take the air out of the ideological fight in which we have been engaged" (Jacobson, RH Reality Check, 7/2).~ "Is Denying Women Abortions the Price of Bipartisanship?" Igor Volsky, Think Progress" "The Wonk Room": Volsky writes that Sen. Orrin Hatch (R-Utah) and Republican colleagues on the Senate Finance Committee reportedly are pushing health care reform legislation that would require insurers participating in a new national health insurance exchange to exclude coverage for abortion services. According to Volsky, the committee"s version of the bill would be the only piece of health care reform legislation "that specifically prohibits -- takes away, rations, if you will -- a medical service." Meanwhile, health care reform legislation being considered by the Senate Health, Education, Labor and Pensions Committee and the House"s three committees that govern health care "leaves the coverage decisions -- the design of the so-called essential benefit packages" -- to the HHS secretary or an expert committee. Volsky notes that approximately one in three U.S. women will have an abortion by age 45 and that private insurers usually cover the procedure. He writes, "As Republicans often argue, Congress should leave benefits decisions to the medical professionals." He adds that "if denying abortion services to women is the price of bipartisanship, then perhaps winning those one or two Republican votes isn"t worth the price of jeopardizing women"s health and well-being" (Volsky, "The Wonk Room," Think Progress, 7/6).~ "House Moves To Lift Bans On Abortion Funding, Needle Exchange, Domestic Partnership and Medical Marijuana in D.C.," Choice Words: The fiscal year 2010 appropriations bill currently under review in the House "would lift a number of reproductive justice-related funding bans" in the District of Columbia, including a ban on using locally-raised funds for abortion, the blog entry states. "Access to abortion in D.C. has been severely limited by anti-choice Congresspeople playing politics with the district," the blog says, noting that Congress has "supreme authority" over the district"s funding. The bill also would end bans on using funds for certain other purposes, such as domestic partnership registration and benefits, according to the blog. The blog concludes that the "fight to lift these funding bans is just beginning" and is an "important first step towards protecting reproductiv

Chicago Team Uses Artificial Intelligence To Diagnose Metastatic Cancer
When doctors are managing care for women with breast cancer, the information available to them profoundly influences the type of care they recommend. Knowing whether a woman"s cancer has metastasized, for instance, directly affects how her doctors will approach treatment -- which may in turn influence the outcome of that treatment.

Light-Treatment Device Developed To Improve Sleep Quality In The Elderly

Sleep disturbances increase as we age. Some studies report more than half of seniors 65 years of age or older suffer from chronic sleep disturbances. Researchers have long believed that the sleep disturbances common among the elderly often result from a disruption of the body"s circadian rhythms - biological cycles that repeat approximately every 24 hours. In recent years, scientists at Rensselaer Polytechnic Institute"s Lighting Research Center and elsewhere have demonstrated that blue light is the most effective at stimulating the circadian system when combined with the appropriate light intensity, spatial distribution, timing, and duration. A team at the Lighting Research Center (LRC) has tested a goggle-like device designed to deliver blue light directly to the eyes to improve sleep quality in older adults. "Light and dark patterns are the major synchronizer of circadian rhythms to the 24-hour solar day," said Mariana Figueiro, Ph.D., Lighting Research Center Light and Health Program director and principal investigator on the project. "Light stimulus travels through the retina, the light-sensitive nerve tissue lining the back wall of the eye, to reach the master clock in the brain. However, a combination of age-related changes in the eye and a more sedentary lifestyle may reduce the amount of light stimulus reaching an older person"s retina, therefore reducing the amount of light for the circadian system." As we age, the lens in the eye thickens and the pupil shrinks, reducing the amount of light passing through to the retina. Making matters worse, in some cases, such as with persons with Alzheimer"s disease, the circadian system may require a stronger light stimulus due to deteriorating neural processes in the brain. These physical and neural changes can lead to muted signals to the circadian system. Factor in environmental influences, such as an indoor lifestyle with less access to daylight, and you have a perfect scenario for the development of irregular sleep-activity patterns, according to Figueiro. The research team explains that a marked increase in daytime lighting levels can counteract the age-dependent losses in retinal light exposure by providing a stronger signal to the circadian system. However, the color and intensity of commercially available lighting systems, like those used in senior residences, assisted-living facilities, and nursing homes, are designed for visual effectiveness and minimal energy use and not necessarily efficacious for generating light to stimulate the older circadian system. Commercially-available "white" light s advertised to treat circadian-related sleep disorders are usually very bright light and can cause glare and compromise compliance. In this project, the light-treatment prototype tested by Figueiro"s team was developed by Topbulb.com, LLC, based on prior LRC light and health research. The device offers an alternative approach using specially designed goggles that deliver blue light spectrally tuned for optimum circadian response. "The goal of this phase of the development project was to create a device in a smaller form factor or envelope that allowed for social inclusion and end-user mobility, while still delivering the required dose of light," said Topbulb.com Senior Developer Philip H. Bonello, Ph.D. The device was worn by eleven subjects between the ages of 51 and 80 years of age. Each subject was exposed to two levels of blue light (about 50 lux and 10 lux) from the personal light-treatment device for 90 minutes on two separate nights. Blood and saliva samples were collected at prescribed times to assess levels of nocturnal melatonin, a hormone used as a marker for the circadian clock, with high levels at night when a person is in a dark environment and low levels during the day. After only one hour of light exposure, the light-induced nocturnal melatonin suppression level was about 35 percent for the low light level and about 60 percent for the high light level. In addition, the higher level of blue light suppressed nocturnal melatonin more quickly, to a greater extent over the course of the 90-minute exposure period, and was maintained after 60 minutes. Having demonstrated its stimulation effect on the circadian system, the researchers believe the device could be subsequently used to increase sleep consolidation and efficiency in older subjects when worn for a prescribed duration at an appropriate time. "The study suggests that the light goggles might be a practical, comfortable, and effective way to deliver light treatment to those suffering from circadian sleep disorders. The next steps are to conduct field studies where we will be testing the effectiveness of this personal light-treatment device on those suffering from circadian-related sleep disorders, while also verifying the acceptance of the a device among the test groups," said Figueiro. Figueiro carried out her research with LRC scientists Andrew Bierman, John Bullough, Ph.D., and Mark Rea, Ph.D. They co-authored a paper detailing the study, "A Personal Light-Treatment Device for Improving Sleep Quality in the Elderly: Dynamics of Nocturnal Melatonin Suppression at Two Exposure Levels," which was recently published in Chronobiology International, Volume 26 Issue 4, 726. This study was supported by the National Institute on Aging (1R41AG029693) through a Small Business Technology Transfer grant to Topbulb.com, LLC, a commercial and residential re for light bulbs.
