Using spider toxins to study the proteins that let nerve cells send out electrical signals, Johns Hopkins researchers say they have stumbled upon a biological tactic that may offer a new way to protect crops from insect plagues in a safe and environmentally responsible way.
A medical first, the case yielded new insights into HIV behavior
The 4-year-old Mississippi child whose HIV infection was put in remission with pre-emptive anti-viral treatment shortly after birth has shown signs of viral recurrence, according to the team that has been following the patient since birth. That team includes Deborah Persaud, M.D., a pediatric HIV specialist at the Johns Hopkins Children’s Center, who performed the initial and all subsequent virological analyses on the case; Hannah Gay, M.D., a pediatrician at the University of Mississippi Medical Center who has been treating and following the child since birth; and immunologist Katherine Luzuriaga, M.D., of the University of Massachusetts Medical School, who conducted immunological monitoring of the child.
Solid leadership, IT and care coordination can mean success
Strong leadership, reliable health care coordination and first-rate information technology are key for academic medical centers seeking to establish successful accountable care organizations, according to a Johns Hopkins study published in the journal Academic Medicine this week.
More could benefit from lower complication rates linked to the procedures, new study shows
Hospitals across the country vary substantially in their use of minimally invasive surgery, even when evidence shows that for most patients, minimally invasive surgery is superior to open surgery, a new study shows. The finding represents a major disparity in the surgical care delivered at various hospitals, the study’s authors say, and identifies an area of medicine ripe for improvement.
Telemedicine could improve access, reduce screening costs
Remote examination of eye scans can be nearly as effective as traditional eye exams in detecting premature newborns with a potentially blinding eye disorder, according to findings from a new federally funded study conducted by investigators at the Johns Hopkins Children’s Center and 12 other institutions.
Gene’s absence influences connections between cells, researchers find
Johns Hopkins researchers have begun to connect the dots between a schizophrenia-linked genetic variation and its effect on the developing brain. As they report July 3 in the journal Cell Stem Cell, their experiments show that the loss of a particular gene alters the skeletons of developing brain cells, which in turn disrupts the orderly layers those cells would normally form.
Although deaths are rare, 'weekend effect' raises questions about after-hours glitches
Children who undergo simple emergency surgeries, such as hernia repairs or appendix removals, on weekends are more likely to suffer complications and even die than children getting the same kind of treatment during the week, according to results of a Johns Hopkins Children’s Center study.
White House honors Pamela Paulk for leadership working with ex-offenders
Johns Hopkins Medicine Senior Vice President for Human Resources Pamela Paulk was recognized at the White House on Monday as a Champion of Change for her work and advocacy in the hiring of ex-offenders.
Investigators at Johns Hopkins are among researchers at 10 institutions selected to carry out a five-year, $30 million patient-centered study designed to compare strategies for preventing fall-related injuries in older adults.
Find likely to aid drug development
Researchers at Johns Hopkins have spotted a strong family trait in two distant relatives: The channels that permit entry of sodium and calcium ions into cells turn out to share similar means for regulating ion intake, they say. Both types of channels are critical to life. Having the right concentrations of sodium and calcium ions in cells enables healthy brain communication, heart contraction and many other processes. The new evidence is likely to aid development of drugs for channel-linked diseases ranging from epilepsy to heart ailments to muscle weakness.
Researchers at Johns Hopkins Bayview Medical Center used two relatively simple tactics to significantly reduce the number of unnecessary blood tests to assess symptoms of heart attack and chest pain and to achieve a large decrease in patient charges.
A Johns Hopkins-led research team has found that motivational interviewing, along with standard education and awareness programs, significantly reduced secondhand smoke exposure among children living in those households.
By analyzing the number of times scientists were cited in others’ papers, the company Thomson Reuters has created a new list of the top 3,215 most highly cited—and therefore most influential— researchers in the world. Seventeen are from the Johns Hopkins University School of Medicine.
Protein, linked to type 2 diabetes, prevents zinc toxicity
Researchers at The Johns Hopkins University report they have deciphered the inner workings of a protein called YiiP that prevents the lethal buildup of zinc inside bacteria. They say understanding YiiP’s movements will help in the design of drugs aimed at modifying the behavior of ZnT proteins, eight human proteins that are similar to YiiP, which play important roles in hormone secretion and in signaling between neurons.
Steven S. Hsiao, an internationally renowned researcher whose innovative experiments on how the brain perceives the shape, size and texture of three-dimensional objects could lead to the development of artificial limbs that can feel, died at The Johns Hopkins Hospital on June 16 of lung cancer. He was 59.
Some cells in the retina pass off worn out parts to supporting cells for disposal
Biologists have long considered cells to function like self-cleaning ovens, chewing up and recycling their own worn out parts as needed. But a new study challenges that basic principle, showing that some nerve cells found in the eye pass off their old energy-producing factories to neighboring support cells to be “eaten.” The find, which may bear on the roots of glaucoma, also has implications for Parkinson’s, Alzheimer’s, amyotrophic lateral sclerosis (ALS) and other diseases that involve a buildup of “garbage” in brain cells.
Star-shaped brain cells “eavesdrop” on neurons, but only when primed
A new study from The Johns Hopkins University shows that the brain cells surrounding a mouse’s neurons do much more than fill space. According to the researchers, the cells, called astrocytes because of their star-shaped appearance, can monitor and respond to nearby neural activity, but only after being activated by the fight-or-flight chemical norepinephrine. Because astrocytes can alter the activity of neurons, the findings suggest that astrocytes may help control the brain’s ability to focus.
Researchers at the Johns Hopkins Kimmel Cancer Center have developed and tested a vaccine that triggered the growth of immune cell nodules within pancreatic tumors, essentially reprogramming these intractable cancers and potentially making them vulnerable to immune-based therapies.
The Johns Hopkins University School of Medicine’s Department of Art as Applied to Medicine is hosting the fifth annual Graphic Medicine Conference, to take place June 26 to June 28 in the Preclinical Teaching Building on the Johns Hopkins medical campus.
Cancer clinicians and a chaplain at the Johns Hopkins Kimmel Cancer Center have developed a new tool to help doctors, nurses and other health care providers talk to dying patients and families who are, literally, praying for a miracle.
