Much has been made about who or what is to blame for the “obesity epidemic” and what can or should be done to stem the tide of rising body mass among the U.S. population.
A new book by a UCLA sociologist turns these concerns on their head by asking two questions. First, how and why has fatness been medicalized as “obesity” in the first place? Second, what are the social costs of this particular way of discussing body size? (more…)
More than half a million adults in California seriously thought about committing suicide during the previous year, according to a new study from the UCLA Center for Health Policy Research.
The study, which uses data from the 2009 California Health Interview Survey (CHIS), is the first by the center to focus on suicide ideation.
In California, suicide is the 10th leading cause of death, the researchers noted. An average of nine deaths by suicide occur each day in the state. (more…)
Portable power supply allows patient to go home while he awaits new heart
Imagine living without a heart. It is possible — if you have a new artificial heart pumping blood through your body. You can even go to the supermarket, watch your kid’s soccer game or go on a hike.
Ronald Reagan UCLA Medical Center has performed its first procedure to remove a patient’s diseased heart and replace it with a SynCardia Temporary Total Artificial Heart.
Chad Washington, 35, underwent the seven-hour transplant surgery at UCLA on Oct. 29, led by Dr. Murray Kwon, an assistant professor of cardiothoracic surgery. (more…)
Planetary scientists have identified water ice and unusually dark deposits within permanently shadowed areas at Mercury’s north pole.
Using data collected by NASA’s MESSENGER spacecraft, a team from UCLA crafted the first accurate thermal model of the solar system’s innermost planet, successfully pinpointing the extremely cold regions where ice has been found on or below the surface.
The researchers say the newly discovered black deposits are a thin crust of residual organic material brought to the planet over the past several million years through impacts by water-rich asteroids and comets. (more…)
Molecular ‘tweezers’ break up toxic aggregations of proteins in mouse model
Last March, researchers at UCLA reported the development of a molecular compound called CLR01 that prevented toxic proteins associated with Parkinson’s disease from binding together and killing the brain’s neurons.
Building on those findings, they have now turned their attention to Alzheimer’s disease, which is thought to be caused by a similar toxic aggregation or clumping, but with different proteins, especially amyloid-beta and tau. (more…)
UCLA infectious diseases doctor played key role in finance strategy for therapy
A new international program, conceived in part by a UCLA physician, has rapidly transformed access to lifesaving anti-malarial drugs by providing cheap, subsidized artemisinin-based combination therapies in seven African countries that account for a quarter of the world’s malaria cases.
The first independent evaluation of the Affordable Medicines Facility–malaria (AMFm) program was recently published in the journal The Lancet. The program is based at the Global Fund in Geneva, an international financing institution dedicated to disbursing funds to prevent and treat infectious diseases. The evaluation shows that the program improved access to key artemisinin combination therapies, or ACTs, which offer broader protection and less antibiotic resistance than anti-malaria medications currently available in those African nations.(more…)
Women with stable but not-so-sexy mates become more distant, critical during periods of high fertility
Long after women have chosen Mr. Stable over Mr. Sexy, they struggle unconsciously with the decision, according to a new study by UCLA researchers who look at subtle changes in behavior during ovulation.
At their most fertile period, these women are less likely to feel close to their mates and more likely to find fault with them than women mated to more sexually desirable men, the research shows. (more…)
UCLA researchers test proposed criteria for diagnosing ‘hypersexual disorder’
The idea that an individual might suffer from a sexual addiction is great fodder for radio talk shows, comedians and late night TV. But a sex addiction is no laughing matter. Relationships are destroyed, jobs are lost, lives ruined.
Yet psychiatrists have been reluctant to accept the idea of out-of-control sexual behavior as a mental health disorder because of the lack of scientific evidence.
Now a UCLA-led team of experts has tested a proposed set of criteria to define “hypersexual disorder,” also known as sexual addiction, as a new mental health condition. (more…)
