Diseased Brain Cells Involved In ALS Motor Neuron Death

February 28, 2020

Two papers by Columbia and Harvard researchers report for the first time that astrocytes (the most abundant non-neuronal cells in the central nervous system), which carry a mutated gene known to cause some cases of amyotrophic lateral sclerosis (ALS/Lou Gehrig's disease), induce motor neuron death. This indicates that astrocytes may contribute to ALS by releasing a toxic factor that damages neurons. These findings, posted online by Nature Neuroscience on April 15, suggest that developing an effe...

Effects Of Two Treatments For Aprosodia Secondary To Acquired Brain Injury

February 27, 2020

Expressive aprosodia, caused by right-hemisphere brain damage, is the inability to change one's voice to express common emotions like joy, anger, and sadness. This study investigated two treatments for expressive aprosodia: cognitive-linguistic and imitative. Participants received the treatments in random order with a 1-month break between treatments. Statistical analysis confirmed that treatment effects were modest to substantial and that 12 participants responded to at least one treatment. O...

African-Americans Have Highest Stroke Rate, Southerners More Likely To Die

February 26, 2020

African-Americans age 65 and younger are more than twice as likely to have a stroke compared with Caucasians in any region, and people who have a stroke are more likely to die in the South than elsewhere, according to researchers at the University of Alabama at Birmingham (UAB) School of Public Health. The findings are from UAB's Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, one of the largest ongoing health studies that includes more than 30,200 U.S. participants. T...

Critical Discussion: Clinical Utility Of PSA Velocity And Doubling Time In Localized Prostate Cancer

February 25, 2020

ORLANDO, FL (UroToday) - Dr. Akihiko Okuyama, Osaka, Japan moderated this panel. He is the President of the Japanese Urological Association. Dr. Moul's work on PSA dynamics was presented and discussed. PSAV and kinetics are utilized in many ways by physicians. It is used to assist in diagnosis and to monitor progression of disease. Dr. Moul pointed out that risk stratification can employ PSAV and PSADT. PSAV is the linear change in PSA over time. PSADT is the log transformation of PSA over time...

Attention Drawn To The World's Health Inequalities

February 24, 2020

When it comes to the inequality in people's health across the globe, says Professor Danny Dorling (University of Sheffield, United Kingdom) "you can say it, you can prove it, you can tabulate it, but it is only when you show it that it hits home." This is the philosophy behind Worldmapper, a collection of cartograms that rescale the size of territories in proportion to the value being mapped (examples of values that are mapped are public health spending, malaria cases, HIV prevalence, and numbe...
