Medicare payment plans are a factor
New research from Johns Hopkins specialists suggests that obese kidney disease patients face not only the usual long odds of a tissue match and organ rejection, but also are significantly less likely than normal-weight people to receive a kidney transplant at all.
Noncombat-related acute and recurrent chronic pain are the leading causes of soldier attrition in modern war, with the return-to-duty rate as low as 2 percent when these soldiers are treated outside the theaters of operation. However, that rate jumps to 95 percent when troops and officers are treated and managed for pain in the field of instead of being sent elsewhere for therapy, according to a new study from a Johns Hopkins anesthesiologist.
Rifapentine is already approved for use in humans
It has no current market, not even a prescription price. Its makers stopped commercial production years ago, because demand was so low. But an antibiotic long abandoned as a weak, low-dose treatment for tuberculosis (TB) may have found renewed purpose, this time as a potent, high-dose fighter against the most common and actively contagious form of the lung disease.
Johns Hopkins scientists have by chance discovered that a widely used means of illuminating cancer cells could undermine studies of the potential value of experimental anti-cancer drugs because the natural “pump” that cells use to clear out the chemical light source alters their chemistry.
Surrounding the small islands of genes within the human genome is a vast sea of mysterious DNA. While most of this non-coding DNA is junk, some of it is used to help genes turn on and off. As reported online this week in Genome Research, Hopkins researchers have now found that this latter portion, which is known as regulatory DNA and contributes to inherited diseases like Parkinson’s or mental disorders, may be more abundant than we realize.
Researchers from Johns Hopkins and the University of Pennsylvania have uncovered another reason why one of the most commonly activated proteins in cancer is in fact so dangerous. As reported in Nature Genetics this week, the Myc protein can stop the production of at least 13 microRNAs, small pieces of nucleic acid that help control which genes are turned on and off.
Researchers at Johns Hopkins have discovered that cancers arising from epigenetic changes - in this case the inappropriate activation of a normally silent gene - develop by becoming addicted to certain growth factors. Reporting online in next week’s Early Edition of the Proceedings of the National Academies of Sciences, the team shows that blocking this “addiction” can greatly prevent cancer growth.
A team of Johns Hopkins scientists has catalogued chemical tags attached to more than 800 genes from 76 human brain samples and collected the first evidence of how these special, inherited epigenetic “marks” might account for different brain functions. The results appear in the December issue of The American Journal of Human Genetics.
Device safely images whole heart or brain, as well as tiny blood vessels
The first 320-slice computed tomography (CT) scanner in North America, the most powerful X-ray imaging machine in its class, has been installed and is in operation at The Johns Hopkins Hospital.
Findings could have wide-reaching effects for other blood tests in the seriously overweight
The extra blood volume produced in the obese may so dilute levels of a telltale protein produced by prostates that the popular PSA test may be significantly less effective for diagnosing prostate cancer in men carrying extra pounds, a new study in The Journal of the American Medical Association suggests.
Grant will fund research to find new uses for "old" FDA-approved drugs
The Robert Packard Center for ALS Research at Johns Hopkins announced today that it has received a three-year, $1.5 million grant from the Cinque Foundation.

Good-Samaritan access to "shock" devices doubles survival from sudden heart attack
Heart experts at Johns Hopkins and elsewhere have evidence that at least 522 lives can be saved annually in the United States and Canada by the widespread placement of automated external defibrillators, the paddle-fitted, electrical devices used to shock and revive people whose hearts have suddenly stopped beating.
Study suggests treatment of vascular diseases might lessen memory loss
Alzheimer’s disease (AD) may progress more rapidly in people with high blood pressure or a form of irregular heartbeat, atrial fibrillation, according to results of a Johns Hopkins study published in the Nov. 6, 2007, issue of Neurology. The findings suggest that treating these conditions may also slow memory loss in people with AD.
Catheterization still gold standard~ but 64-slice scanners are coming on strong
A study by an international team of cardiac imaging specialists, led by researchers at Johns Hopkins, concludes that sophisticated computed tomography (CT) scans of the heart and its surrounding arteries are almost as reliable and accurate as more invasive procedures to check for blockages.

Mouse experiments reveal "flight or fight" hormone's role
Both extensive psychological research and personal experiences confirm that events that happen during heightened states of emotion such as fear, anger and joy are far more memorable than less dramatic occurrences. In a report this week in Cell, Johns Hopkins researchers and their collaborators at Cold Spring Harbor and New York University have identified the likely biological basis for this: a hormone released during emotional arousal “primes” nerve cells to remember events by increasing their chemical sensitivity at sites where nerves rewire to form new memory circuits.
Johns Hopkins researchers say they have figured out how human and all animal cells tune in to a key signal, one that literally transmits the instructions that shape their final bodies. It turns out the cells assemble their own little radio antenna on their surfaces to help them relay the proper signal to the developmental proteins “listening” on the inside of the cell.

Two Events, Art Contest to Mark Social Work Centennial
Grinding poverty, splintered families, tuberculosis, syphilis, typhoid and polio were daily realities for the poor in 19th century Baltimore. For many, their only help was provided by the fledging social worker services of The Johns Hopkins Hospital. More than a century later, the need - and the mission - remain remarkably similar for Johns Hopkins social workers, and new problems have been added to the urban mix: widespread drug abuse, immigration, an aging population, crime and homelessness. It is this urgent and abiding need that defines the role of the Hopkins social worker.
