Racial disparities in access to kidney transplantation persist in the United States. New research indicates that registering Black patients on the kidney transplant waitlist at a slightly higher level of kidney function compared with white patients might lessen racial inequality in patients' wait time prior to kidney failure onset, and ultimately improve racial equity in access to kidney transplantation.
Washington, DC (February 23, 2021) -- Despite efforts to address them, racial disparities in access to kidney transplantation persist in the United States. New research published in an upcoming issue of JASN indicates that policy changes surrounding patients' eligibility to be put on kidney transplant waitlists might help address these disparities.
There are studies indicating that chronic kidney disease may progress more rapidly in Black individuals, especially during advanced stages of disease. This may disadvantage Blacks compared with whites in terms of the time that could theoretically be used to prepare for transplantation. In addition, Black patients are also referred later for transplant evaluation than white patients.
In this latest study, Elaine Ku, MD (UCSF), Kirsten Johansen, MD (Hennepin Healthcare and University of Minnesota), and their colleagues quantified racial disparities in wait time prior to the onset of kidney failure based on current national policies using different equations that estimate kidney function. They then determined the level of kidney function at which Black patients would need to be referred and waitlisted to equalize the potential wait times among Black and white patients using the different equations.
The investigators found that registering Blacks on the waitlist at a slightly higher level of kidney function compared with whites might lessen racial inequality in patients' wait time prior to kidney failure onset, and ultimately improve racial equity in access to kidney transplantation.
"Regardless of which equation we used to estimate kidney function, Black patients had less potential time available for waitlist registration than white patients; however, we found that use of a higher kidney function threshold to allow for earlier eligibility for waitlisting in Blacks could theoretically reduce the racial disparity in time spent in the advanced stages of chronic kidney disease," said Dr. Ku.

MINNEAPOLIS - More than two-thirds of people with migraine do not get enough exercise, according to a preliminary study released today, February 23, 2021, that will be presented at the American Academy of Neurology's 73rd Annual Meeting being held virtually April 17 to 22, 2021. The study found that people who do get a minimum of two-and-a-half hours of moderate to vigorous exercise a week had a reduced rate of migraine triggers like stress, depression and sleep problems.
"Migraine is a disabling condition that affects millions of people in the United States, and yet regular exercise may be an effective way to reduce the frequency and intensity of some migraines," said study author Mason Dyess, D.O., of the University ...

One in four women over age 65 is unable to walk two blocks or climb a flight of stairs. Known as mobility disability, it is the leading type of incapacity in the United States and a key contributor to a person's loss of independence. New research from Herbert Wertheim School of Public Health and Human Longevity Sciences at UC San Diego suggests that light-intensity physical activity, including shopping or a casual walk, may protect mobility in older women.
Published in the February 23, 2021 online issue of JAMA Network Open, researchers found that women ...

Isn't it convenient when office building windows adaptively darken according to the intensity of sunlight? Or when standard glasses turn into sunglasses under the sun and switch back as you enter a building? Such feats are possible thanks to photochromic materials, whose optical (and other) properties change radically when irradiated by visible or ultraviolet light.
Today, virtually all fast-switching photochromic materials are made using organic compounds. Unfortunately, this makes them considerably expensive and complex to synthesize, requiring multi-step processes that are difficult to scale up for mass production. So, despite the myriad ...

Thuwal/Helsinki/Leipzig. Alkanes, an important component of fuels for combustion engines and an important class of urban trace gases, react via another reaction pathways than previously thought. These hydrocarbons, formerly called paraffins, thus produce large amounts of highly oxygenated compounds that can contribute to organic aerosol and thus to air pollution in cities. An international research team has now been able to prove this through laboratory experiments with state-of-the-art measurement technology at the University of Helsinki and the Leibniz Institute for Tropospheric ...

LOS ALAMOS, N.M., February 23, 2021--A revolutionary machine-learning (ML) approach to simulate the motions of atoms in materials such as aluminum is described in this week's Nature Communications journal. This automated approach to "interatomic potential development" could transform the field of computational materials discovery.
"This approach promises to be an important building block for the study of materials damage and aging from first principles," said project lead Justin Smith of Los Alamos National Laboratory. "Simulating the dynamics of interacting atoms is a cornerstone of understanding and developing new materials. Machine learning methods are providing computational scientists new tools to accurately and efficiently conduct these atomistic ...

Neuroblastoma is a cancer that develops in nerve tissue, most commonly in the glands around the kidneys. The gene MYCN is overexpressed in 20-25% of neuroblastoma, and MYCN-amplified neuroblastoma contributes to a considerable percentage of pediatric cancer-related deaths.
Anthony Faber, Ph.D., and a team of researchers at VCU Massey Cancer Center were awarded a grant from the American Cancer Society to study how MYCN and an abundance of iron can drive cancer cell death in neuroblastoma and potentially be targeted with novel treatments. This award is the first part of a potential two-stage grant worth a combined total of $600,000.
"Iron is a double-edged sword in a cancer cell. It can help the cancer grow and survive, but it also creates ...

Schizophrenia, a chronic, neurological brain disorder, affects millions of people around the world. It causes a fracture between a person's thoughts, feelings and behavior. Symptoms include delusions, hallucinations, difficulty processing thoughts and an overall lack of motivation. Schizophrenia patients have a higher suicide rate and more health problems than the general population, and a lower life expectancy.
There is no cure for schizophrenia, but the key to treating it more effectively is to better understand how it arises. And that, according to Ryuta Mizutani, professor of applied biochemistry at Tokai University in Japan, means studying the structure of brain tissue. Specifically, it means comparing the brain tissues of schizophrenia patients with those ...

Even as more people are logging onto popular video chat platforms to connect with colleagues, family and friends during the COVID-19 pandemic, Stanford researchers have a warning for you: Those video calls are likely tiring you out.
Prompted by the recent boom in videoconferencing, communication Professor Jeremy Bailenson, founding director of the Stanford Virtual Human Interaction Lab (VHIL), examined the psychological consequences of spending hours per day on these platforms. Just as "Googling" is something akin to any web search, the term "Zooming" has become ubiquitous and a generic verb to replace videoconferencing. Virtual meetings have skyrocketed, with hundreds of millions happening daily, as social distancing protocols have kept people apart physically.
