Johns Hopkins-led study suggests imaging studies add no value for patients getting epidural steroid injections
Johns Hopkins-led research suggests that routine MRI imaging does nothing to improve the treatment of patients who need injections of steroids into their spinal columns to relieve pain. Moreover, MRI plays only a small role in a doctor’s decision to give these epidural steroid injections (ESIs), the most common procedure performed at pain clinics in the United States
Looking for ways to halt the uncontrolled growth of cancer cells, scientists at Johns Hopkins have found that a new class of drugs, called PARP inhibitors, may block the ability of pre-leukemic cells to repair broken bits of their own DNA, causing these cells to self-destruct. Results of their experiments, expected to be presented at the 53rd Annual Meeting of the American Society of Hematology in San Diego, Dec. 12, have already prompted clinical trials of the drugs in patients with aggressive pre-leukemic conditions, who have few treatment options.
People within the Johns Hopkins community have long known that Lillie Shockney is an amazing nurse. Now she’s got the moniker to prove it. Shockney, administrative director of the Johns Hopkins Avon Breast Center since 1997, was selected as this year’s “Amazing Nurse” in a national contest to celebrate and reward nurses’ value, sponsored by the Johnson & Johnson Campaign for Nursing’s Future. Shockney’s work with breast cancer patients was recognized by Johnson & Johnson during the 2011 CNN Heroes: An All-Star Tribute show in Los Angeles on December 11.

Having both ovaries removed before age 45 is strongly associated with low-bone mineral density and arthritis in later years, according to a new study by Johns Hopkins oncologists and epidemiologists. The analysis covered several thousand women who took part in a U.S. government-sponsored, multiyear national health study, and excluded women whose ovaries were removed due to cancer.
Working with human breast cells, researchers at the Johns Hopkins Kimmel Cancer Center have shown how the inactivation of a single copy of the breast cancer gene BRCA1 leaves breast cells vulnerable to cancer by reducing their ability to repair DNA damage, causing genetic instability. An inherited mutation in BRCA1 is the leading risk factor for hereditary breast cancer, prompting preventive mastectomies or close monitoring. The new findings may aid development of drugs to prevent hereditary breast cancer and tools to identify women who benefit most from prophylactic treatments.
Johns Hopkins Kimmel Cancer Center scientists report that sharp rises in levels of reactive oxygen molecules, and the inflammation that results, trigger biochemical changes that silence genes in a pattern often seen in cancer cells. The researchers confirmed this gene-silencing effect in mice that develop inflammation-induced colon cancer.

Removing organs for transplant unless person explicitly opts out of donation before death not best way to address scarcity, raises sticky ethical questions
Changing the organ donation process in this country from opt-in — by, say, checking a box on a driver’s license application— to opt-out, which presumes someone’s willingness to donate after death unless they explicitly object while alive, would not be likely to increase the donation rate in the United States, new Johns Hopkins research suggests.
A team of researchers from the Johns Hopkins Children’s Center, Vanderbilt University and elsewhere have demonstrated that high blood pressure and anemia together put children with sickle cell disease (SCD) at serious danger for symptomless or so-called “silent” strokes, although either condition alone also signaled high risk.

Coronary calcium test proves to be key indicator of low risk compared with other risk factors
If your doctor says you have a negative stress test, or that your cholesterol or blood pressure are normal, how assured can you be that you're not likely to have a heart attack in the next seven to 10 years? Assessing traditional risk factors, such as age, high blood pressure, cholesterol, smoking and family history can estimate a person's risk, but the picture is not always clear-cut. Some newer tests can be offered to provide reassurance or guidance about the need for medications or further testing.
Earliest North American human predecessors may have been tree-dwellers
Johns Hopkins researchers have identified the first ankle and toe bone fossils from the earliest North American true primate, which they say suggests that our earliest forerunners may have dwelled or moved primarily in trees, like modern day lemurs and similar mammals.
Johns Hopkins research finds two programs for obese patients lead to significant, sustainable weight loss

Study shows resistance is reversible
In dozens of experiments in mice and in human cancer cells, a team of Johns Hopkins scientists has closely tied production of a cancer-causing protein called TWIST to the development of estrogen resistance in women with breast cancer. Because estrogen fuels much breast cancer growth, such resistance — in which cancers go from estrogen positive to estrogen negative status — can sabotage anticancer drugs that work to block estrogen and prevent disease recurrence after surgery. Estrogen resistance develops in over half of women taking estrogen-blocking medications, such as tamoxifen, and exists from the start in many other women.
A study of the long-term consequences of pelvic inflammatory disease (PID) led by researchers at the Johns Hopkins Children’s Center shows repeated bouts of the disease can double a woman’s risk of infertility and quadruple her risk of chronic pelvic pain. Teenage girls with recurrent PID also face dire consequences, the researchers found, including a fivefold risk of chronic pelvic pain and alarming rates of infertility.

Potential target for chemoprevention
Johns Hopkins Kimmel Cancer Center scientists report that sharp rises in levels of reactive oxygen molecules, and the inflammation that results, trigger biochemical changes that silence genes in a pattern often seen in cancer cells. The researchers confirmed this gene-silencing effect in mice that develop inflammation-induced colon cancer.
Johns Hopkins researchers uncover how light causes the eye to react
You’ve seen it on television: A doctor shines a bright light into an unconscious patient’s eye to check for brain death. If the pupil constricts, the brain is OK, because in mammals, the brain controls the pupil. Or does it? Now, researchers at Johns Hopkins have discovered that in most mammals, in fact in most vertebrates, the pupil can constrict without any input from the brain.
Johns Hopkins’ Armstrong Institute for Patient Safety and Quality has been awarded $10 million for a project designed to reduce surgical-site infections and other major complications of colon surgery.

Using a patient’s own stem cells, researchers at Johns Hopkins have corrected the genetic alteration that causes sickle cell disease (SCD), a painful, disabling inherited blood disorder that affects mostly African-Americans. The corrected stem cells were coaxed into immature red blood cells in a test tube that then turned on a normal version of the gene.
Study demonstrates “proof of principle” in new way to restore normal heart rhythm
Each year in the United States, more than 200,000 people have a cardiac defibrillator implanted in their chest to deliver a high-voltage shock to prevent sudden cardiac death from a life-threatening arrhythmia. While it’s a necessary and effective preventive therapy, those who’ve experienced a defibrillator shock say it’s painful, and some studies suggest that the shock can damage heart muscle.
Nerve degeneration detected with skin biopsies
Oxaliplatin, a platinum-based anticancer drug that’s made enormous headway in recent years against colorectal cancer, appears to cause nerve damage that may be permanent and worsens even months after treatment ends. The chemotherapy side effect, described by Johns Hopkins researchers in the September issue of Neurology, was discovered in what is believed to be the first effort to track oxaliplatin-based nerve damage through relatively cheap and easy punch skin biopsies.

In her new role, Swiger will write for internal publications and manage media relations on a number of topics of great importance to Hopkins, including patient safety, diversity and technology.
Researchers discover dozens of genetic variants associated with increased risk of hypertension, stroke and other cardiovascular diseases
A study involving more than 200,000 people worldwide has identified 29 DNA sequence variations in locations across the human genome that influence blood pressure. These genes, whose sequence changes are associated with alterations in blood pressure and are linked to heart disease and stroke, were found with the help of decades' worth of population data that were pooled and analyzed by a large international consortium, including Johns Hopkins researchers.
Johns Hopkins urologist Patrick Walsh, M.D., who pioneered nerve-sparing prostate removal surgery to reduce the chance of impotence and incontinence, will deliver the keynote address at a fundraising dinner on the Johns Hopkins medical campus on Sept. 14. The event is in advance of Prostate Cancer Awareness Week, Sept. 18-24.
No, this isn't Jurassic Park. Researchers at the Johns Hopkins University School of Medicine with help from an amateur fossil hunter in College Park, Md., have described the fossil of an armored dinosaur hatchling. It is the youngest nodosaur ever discovered, and a founder of a new genus and species that lived approximately 110 million years ago during the Early Cretaceous Era. Nodosaurs have been found in diverse locations worldwide, but they've rarely been found in the United States. The findings are published in the September 9 issue of the Journal of Paleontology.
Infectious disease and disaster preparedness experts at Johns Hopkins Medicine say the premise of the soon-to-be-released Hollywood movie Contagion, in which a lethal airborne virus spreads quickly around the globe, is realistic and should serve as a reminder that the United States has much work to do to prepare for a serious national emergency posed by a deadly virus that spreads quickly.
Johns Hopkins study suggests medical students may “learn” to treat nonwhite patients differently than white patients
New Johns Hopkins research shows that medical students — just like the general American population — may have unconscious if not overt preferences for white people, but this innate bias does not appear to translate into different or lesser health care of other races.
Johns Hopkins researchers say data show aging alone, not hormonal impact of menopause, explains increasing number of deaths as women age
Contradicting the long-held medical belief that the risk of cardiovascular death for women spikes sharply after menopause, new research from Johns Hopkins suggests instead that heart disease mortality rates in women progress at a constant rate as they age.
Johns Hopkins researchers say they have developed a formula to predict which heart transplant patients are at greatest risk of death in the year following their surgeries, information that could help medical teams figure out who would benefit most from the small number of available organs.
As a public service, the Johns Hopkins Department of Emergency Medicine is providing doctors, nurses and paramedics to staff medical tents at the Baltimore Grand Prix, slated for Sept. 2-4, at the request of Baltimore City officials and event organizers.
Nerve cells that regulate everything from heart muscle to salivary glands send out projections known as axons to their targets. By way of these axonal processes, neurons control target function and receive molecular signals from targets that return to the cell body to support cell survival. Now, Johns Hopkins researchers have revealed a molecular mechanism that allows a signal from the target to return to the cell body and fulfill its neuron-sustaining mission.
Johns Hopkins study suggests unfamiliarity with surroundings may contribute to more frequent serious medication errors
Temporary staff members working in a hospital’s fast-paced emergency department are twice as likely as permanent employees to be involved in medication errors that harm patients, new Johns Hopkins research suggests.
Many resort to emergency department for minor medical needs that could have been cared for in outpatient clinic
Providing access to an outpatient clinic isn’t enough to keep some trauma patients who have been discharged from the hospital from returning to the emergency department (ED) for follow-up care, even for such minor needs as pain medication refills and dressing changes, according to new Johns Hopkins research.
Doctors can peer inside the human body to look for tumors, detect a blockage in an artery or see a crack in a bone, but common afflictions like bacterial and viral infections are far more difficult to track, and even the most sophisticated imaging devices can only offer a less-than-definitive answer.“Although CT scans and MRIs can spot disease, they can’t always reliably tell a physician if that suspicious shade they see on the screen is a tumor or a hotbed of bacteria,” says imaging innovator and infectious disease specialist Sanjay Jain, M.D., of Johns Hopkins Children’s Center.

A $30 million gift from the Commonwealth Foundation for Cancer Research has enabled the Johns Hopkins Kimmel Cancer Center to establish a Center for Personalized Cancer Medicine. The gift from the Richmond, VA- based foundation, will be used to support research and the development of new technologies that pinpoint the novel genetic characteristics of each patient’s cancer. Hopkins scientists and officials say this will speed the development of therapies based on an individual cancer patient’s genetic “fingerprint.”
Acclaimed checklist program gives tenfold return on investment
A quality improvement program that saves lives by dramatically reducing potentially lethal bloodstream infections in hospital intensive-care units across the state of Michigan also saves those hospitals an average of $1.1 million a year, new Johns Hopkins research suggests.
Jane C. Shivnan, MScN, RN, AOCN, has been named executive director of clinical quality and nursing at Johns Hopkins Medicine International (JHI), the international arm of Johns Hopkins Medicine. Shivnan has more than 20 years of health care leadership experience, including service as executive director of the Institute for Johns Hopkins Nursing and as the director of the Institute’s Office of Global Nursing. In her new role, Shivnan will provide strategic oversight and leadership in JHI’s clinical, consulting and knowledge transfer activities. She will also continue to serve the Institute for Johns Hopkins Nursing as executive director, which will create synergy to further leverage the expertise of Hopkins nurses.
Plastic surgeons say they have developed a new surgical technique for complex skull reconstruction that could improve functional and aesthetic outcomes in cases that have previously been deemed impossible or unsafe and left patients with unsightly skull deformities requiring them to wear a helmet.
Current teaching structure hasn’t changed in 30 years
Leaders in biomedical education at Johns Hopkins University School of Medicine are calling for a radical new approach to post-graduate training in the life sciences to address significant challenges, including an avalanche of new discoveries in the last decade and the need to transcend traditional departmental boundaries to understand biological processes at multiple levels.
The presence of calcium in coronary arteries is a much better predictor of heart attack and stroke than C-reactive protein among people with normal levels of LDL cholesterol, according to a study of more than 2,000 people led by a Johns Hopkins heart specialist.
Project to Fund Systematic Review of Chronic Wound Treatment Research to Identify Wound Care Best Practices
An estimated $25 billion is spent annually on treating chronic wounds on patients in the United States. These chronic wounds deeply affect the quality of life of more than six million people who have them. The most common types of chronic skin wounds and skin ulcers are related to venous disease (conditions related to or caused by veins that become diseased or abnormal). Many treatment options are available, but the quality of evidence showing which treatments work better than others is often lacking. It is hard to prove which treatments are effective and should be the standards of care.

Researchers at the Johns Hopkins University School of Medicine have found a protein normally involved in blood pressure regulation in a surprising place: tucked within the little “power plants” of cells, the mitochondria. The quantity of this protein appears to decrease with age, but treating older mice with the blood pressure medication losartan can increase protein numbers to youthful levels, decreasing both blood pressure and cellular energy usage. The researchers say these findings, published online during the week of August 15, 2011, in the Proceedings of the National Academy of Sciences, may lead to new treatments for mitochondrial–specific, age-related diseases, such as diabetes, hearing loss, frailty and Parkinson’s disease.
JAMA paper could reverse longstanding guidelines and advice for African-American patients with kidney disease
For years, medical studies have reached the same conclusion: African-American patients do better on kidney dialysis than their white counterparts. But new Johns Hopkins research, published in the Journal of the American Medical Association, shows that younger blacks — those under the age of 50 — actually do much worse on dialysis than equally sick whites who undergo the same blood-filtering process.
While the battle over the legality of the Affordable Care Act’s mandate requiring most individuals to purchase health insurance continues to be fought, its impact on the quality and cost of care and what it would mean for patients and their physicians has been largely overlooked.
Diet and genetics dictate adult jaw shape
Researchers at Johns Hopkins found that use over time and not just genetics informs the structure of jaw bones in human populations. The researchers say these findings may be used to predict the diet of an ancient population, even if little evidence exists in the fossil record. It can also make it easier for scientists to pinpoint the genetic relationship between fossils.
Johns Hopkins Kimmel Cancer Center scientists have completed a comprehensive map of genetic mutations occurring in the second-most common form of brain cancer, oligodendroglioma. The findings, reported in the Aug. 4 issue of Science, also appear to reveal the biological cause of the tumors, they say.
A combination of several well-known safety procedures could greatly reduce patient-harming errors in the use of radiation to treat cancer, according to a new study led by Johns Hopkins researchers.
Smoke-free homes still the best choice
A Johns Hopkins Children’s Center study of Baltimore City children who have asthma and live with smokers shows that indoor air cleaners can greatly reduce household air pollution and lower the rates of daytime asthma symptoms to those achieved with certain anti-inflammatory asthma drugs. Although the air cleaners improved the overall air quality in homes, they did not reduce air nicotine levels and did not counter all ill effects of second-hand smoke, the researchers warn.
-Five-year research project will be funded by the NIH
Johns Hopkins scientists have launched a pioneering research program to create, for the first time, human platelet cells from stem cells in order to study inherited blood clotting abnormalities ranging from clots that cause heart attacks and stroke to bleeding disorders. The study is funded by a $9 million grant from the National Institutes of Health (NIH) as part of a nationwide initiative to examine how genetic variations cause heart, lung and blood diseases.
A national transplant policy change designed to give African-American patients greater access to donor kidneys has sliced in half the racial disparities that have long characterized the allocation of lifesaving organs, new Johns Hopkins research suggests.
Potential uses include facial reconstruction for soldiers’ blast injuries
Biomedical engineers at Johns Hopkins have developed a new liquid material that in early experiments in rats and humans shows promise in restoring damaged soft tissue relatively safely and durably. The material, a composite of biological and synthetic molecules, is injected under the skin, then “set” using light to form a more solid structure, like using cold to set gelatin in a mold. The researchers say the product one day could be used to reconstruct soldiers' faces marred by blast injuries.
One in three meth users reports sex with an HIV-infected person
A study by researchers at Johns Hopkins Children’s Center and elsewhere shows that methamphetamine use can fuel HIV infection risk among teenage boys and young men who have sex with men (MSM), a group that includes openly gay and bisexual men as well as those who have sex with men but do not identify themselves as gay or bisexual.
Stent makes "coiling" surgery more promising option
The addition of a simple stent can help prevent potentially lethal blood vessel bulges in the brain from recurring after they are repaired in a minimally invasive "coiling" procedure, according to new research by Johns Hopkins physicians.
Powerful new technologies that zoom in on the connections between human genes and diseases have illuminated the landscape of cancer, singling out changes in tumor DNA that drive the development of certain types of malignancies such as melanoma or ovarian cancer.
Now several major biomedical centers have collaborated to shine a light on head and neck squamous cell cancer. Their large-scale analysis has revealed a surprising new set of mutations involved in this understudied disease.
In back-to-back papers published online July 28 in Science, researchers from the Broad Institute, Dana-Farber Cancer Institute, Johns Hopkins Kimmel Cancer Center, the University of Pittsburgh, and the University of Texas MD Anderson Cancer Center have confirmed genetic abnormalities previously suspected in head and neck cancer, including defects in the tumor suppressor gene known as p53. But the two teams also found mutations in the NOTCH family of genes, suggesting their role as regulators of an important stage in cell development may be impaired.
Findings help explain tamoxifen resistance in some breast cancers
Using human breast cancer cells and the protein that causes fireflies to glow, a Johns Hopkins team has shed light on why some breast cancer cells become resistant to the anticancer effects of the drug tamoxifen. The key is a discovery of two genetic "dimmer switches" that apparently control how a breast cancer gene responds to the female hormone estrogen.
Female patients make up most of those who could benefit
Hard-to-match kidney transplant candidates who receive a treatment designed to make their bodies more accepting of incompatible organs are twice as likely to survive eight years after transplant surgery as those who stay on dialysis for years awaiting compatible organs, new Johns Hopkins research finds.
When The Johns Hopkins Hospital in Baltimore opens a new, 1.6 million square-foot patient care building with two 12-story towers in April 2012, an ultra-modern, 30,000 square-foot kitchen expansion will serve the food and nutrition needs of patients, visitors and employees. The addition will double the hospital’s kitchen and be a state-of-the-art facility where the staff will prepare almost 12,000 meals daily for inpatients and customers in the cafeteria and other food venues.
Landon S. King, M.D., the David Marine Professor of medicine and biological chemistry and director of the Division of Pulmonary and Critical Care Medicine has been named the next vice dean for research at Johns Hopkins Medicine, effective Sept. 1.
Johns Hopkins scientists have developed a gene-based test to distinguish harmless from precancerous pancreatic cysts. The test may eventually help some patients avoid needless surgery to remove the harmless variety. A report on the development is published in the July 20 issue of Science Translational Medicine.
The investigators estimate that fluid-filled cysts are identified in more than a million patients each year, most of whom have undergone CT or MRI scans to evaluate non-specific symptoms, such as abdominal pain and swelling.
For the 21st year in a row, The Johns Hopkins Hospital has taken the top spot in U.S.News & World Report’s annual rankings of American hospitals, placing first in five medical specialties and in the top five in 10 others.
Johns Hopkins University School of Medicine program teaches medicine and art
Eo Trueblood will graduate with a degree from medical school, but instead of caring for patients or doing research, his job will be to create artwork to convey concepts in medicine that are difficult to describe in words or capture in photographs. Along with the five other students in his class, Trueblood will graduate in 2012 with a Master of Arts degree in Medical and Biological Illustration from the Johns Hopkins Department of Art as Applied to Medicine. The department celebrates its 100th anniversary on July 20. It was the first and is the oldest such program in the world, and is one of only five such accredited programs in North America.
A team of AIDS experts at Johns Hopkins and other institutions have embarked on a joint five-year research initiative to cure HIV disease by finding ways to completely purge the virus from the body in people already successfully suppressing the virus with antiretroviral drug therapy.
Johns Hopkins expert calls for testing and mandatory reporting
A Johns Hopkins infectious disease expert is calling for all sexually active American women age 40 and older to get tested for the parasite Trichomonas vaginalis after new study evidence found that the sexually transmitted disease (STD) is more than twice as common in this age group than previously thought. Screening is especially important because in many cases there are no symptoms.
In a large and comprehensive investigation into the underlying causes of sudden cardiac death (SCD) -- a surreptitious killer of hundreds of thousands annually in the United States -- researchers have discovered a variation in the genome's DNA sequence that is linked to a significant increase in a person's risk of SCD.
New device is designed for elderly and high-risk patients with severe aortic disease
Heart experts at Johns Hopkins have begun testing a new device designed to replace blocked aortic valves in patients for whom traditional open-heart surgery is considered too risky, such as elderly patients and those with other serious medical conditions. The testing is part of a nationwide study to evaluate the device, which is deployed in a minimally invasive way. The first two Maryland patients to receive the device had it put in place by Johns Hopkins doctors on July 8, 2011.
New Programs of Excellence to study sugar molecules
The National Heart, Lung and Blood Institute, one of the National Institutes of Health, has awarded two groups at the Johns Hopkins University School of Medicine each approximately $2.3 million a year for seven years to establish two Programs of Excellence in Glycosciences. Gerald Hart, Ph.D., director of biological chemistry and Ronald Schnaar, Ph.D., professor of pharmacology and molecular sciences, will lead these independent efforts to better understand the roles of sugars in the molecular mechanisms of disease, particularly lung and heart diseases.
Johns Hopkins and South African scientists have further compelling evidence that new, simpler and shorter treatments with antibiotic drugs could dramatically help prevent tens of millions of people worldwide already infected with the bacterium responsible for tuberculosis, and especially those co-infected with HIV, from developing full-blown TB. That population includes as many as 22 million in sub-Saharan Africa who are already HIV positive and at high risk of also picking up TB, which is endemic to the region, plus another 50,000 in the United States who are similarly HIV positive and at high risk of catching the lung infection.
Identifying a suitable donor for leukemia and lymphoma patients who need bone marrow transplants may be far easier now that results of two clinical trials show transplant results with half-matched bone marrow or umbilical cord blood are comparable to fully matched tissue, thanks in large part to the availability of effective antirejection drugs and special post-transplant chemotherapy. The finding means that nearly all patients in need of a transplant can find donors, according to Johns Hopkins scientists who participated in the trials.

Scientists at Johns Hopkins have provided more clues to one of the least understood phenomena in some cancers: why the “ends caps” of cellular DNA, called telomeres, lengthen instead of shorten. In a study published online June 30 in Science Express, the Johns Hopkins researchers say they have identified two genes that, when defective, may cause these telomere elongations.
Johns Hopkins researchers find disparity in outcomes after elective plastic surgery
Obese patients are nearly 12 times more likely to suffer a complication following elective plastic surgery than their normal-weight counterparts, according to new research by Johns Hopkins scientists.
Team reconstituted stem cells’ “family tree”
A Johns Hopkins team has discovered in young adult mice that a lone brain stem cell is capable not only of replacing itself and giving rise to specialized neurons and glia – important types of brain cells – but also of taking a wholly unexpected path: generating two new brain stem cells.
Current drug standards may lead to under- and overdosing
Generic anti-epilepsy drugs, pharmaceutical products similar to brand-name versions, save consumers billions of dollars each year, but some are different enough from branded formulations that they may not be effective, particularly if patients switch between two generic drugs, a new study by Johns Hopkins researchers suggests. A report on the study, published online and in an upcoming issue of Annals of Neurology, raises questions about whether some generic products are safe and effective when a narrow dose range separates patients from help and harm.
Becker’s Hospital Review magazine has selected Edward D. Miller, M.D., dean of the medical faculty and CEO of Johns Hopkins Medicine, as one of 65 prominent Physician Leaders of Hospitals and Health Systems in America. The award is based on the physician leaders’ “arrays of experience in medicine and management” along with their strong clinical and financial backgrounds.
Findings reveal chaos in biochemical alterations of cancer cells
Using the latest gene sequencing tools to examine so-called epigenetic influences on the DNA makeup of colon cancer, a Johns Hopkins team says its results suggest cancer treatment might eventually be more tolerable and successful if therapies could focus on helping cancer cells get back to normal in addition to strategies for killing them.
Patients with chronic obstructive pulmonary disease (COPD) who use inhaled corticosteroids to improve breathing for more than six months have a 27 percent increased risk of bone fractures, new Johns Hopkins-led research suggests.

Johns Hopkins Medicine International, the international arm of Johns Hopkins Medicine, has elected Christopher W. Kersey, M.D., M.B.A., to become its new chairman of the board.
Johns Hopkins researchers have found a likely explanation for the slow growth of the most common childhood brain tumor, pilocytic astrocytoma. Using tests on a new cell-based model of the tumor, they concluded that the initial process of tumor formation switches on a growth-braking tumor-suppressor gene, in a process similar to that seen in skin moles.
--Results may provide new strategy to prevent amputations
Blood vessels and supporting cells appear to be pivotal partners in repairing nerves ravaged by diabetic neuropathy, and nurturing their partnership with nerve cells might make the difference between success and failure in experimental efforts to regrow damaged nerves, Johns Hopkins researchers report in a new study.
--Two Johns Hopkins researchers argue many measures contain "surveillance bias"
With an increased emphasis on grading hospitals and a push to withhold payments from hospitals who don't meet certain standards, two Johns Hopkins researchers argue that more attention needs to be paid to the quality of the measurement tools used to praise and punish.
People who use a mist inhaler to deliver a drug widely prescribed in more than 55 countries to treat chronic obstructive pulmonary disease (COPD) may be 52 percent more likely to die, new Johns Hopkins-led research suggests.
Johns Hopkins researchers uncover the source of the visual system’s “false alarms”
On rare occasion, the light-sensing photoreceptor cells in the eye misfire and signal to the brain as if they have captured photons, when in reality they haven’t. For years this phenomenon remained a mystery. Reporting in the June 10 issue of Science, neuroscientists at the Johns Hopkins University School of Medicine have discovered that a light-capturing pigment molecule in photoreceptors can be triggered by heat, as well, giving rise to these false alarms.
Findings also solve long-standing paradox
Cells grow abundant when oxygen is available, and generally stop when it is scarce. Although this seems straightforward, no direct link ever has been established between the cellular machinery that senses oxygen and that which controls cell division. Now, in the June 10 issue of Molecular Cell, researchers at Johns Hopkins report that the MCM proteins, which promote cell division, also directly control the oxygen-sensing HIF-1 protein.
Patient safety expert Peter J. Pronovost, M.D., Ph.D., a professor of anesthesiology and critical care medicine at the Johns Hopkins University School of Medicine, has been named director of the newly established Armstrong Institute for Patient Safety and Quality at Johns Hopkins.
Johns Hopkins researchers solve mystery of Warburg effect
It's long been known that cancer cells eat a lot of sugar to stay alive. In fact, where normal, noncancerous cells generate energy from using some sugar and a lot of oxygen, cancerous cells use virtually no oxygen and a lot of sugar. Many genes have been implicated in this process and now, reporting in the May 27 issue of Cell, researchers at the Johns Hopkins University School of Medicine have discovered that this so-called Warburg effect is controlled.
Revealing another part of the story of muscle development, Johns Hopkins researchers have shown how the cytoskeleton from one muscle cell builds finger-like projections that invade into another muscle cell’s territory, eventually forcing the cells to combine.
The oral antifungal drug itraconazole, most commonly used to treat nail fungus, may keep prostate cancer from worsening and delay the need for chemotherapy in men with advanced disease. Details of the finding, from a clinical trial led by Johns Hopkins experts, are scheduled for presentation on Saturday, June 4 at the 2011 American Society of Clinical Oncology (ASCO) annual meeting (abstract #4532).
Overweight and obese people looking to drop some pounds and considering one of the popular low-carbohydrate diets, along with moderate exercise, need not worry that the higher proportion of fat in such a program compared to a low-fat, high-carb diet may harm their arteries, suggests a pair of new studies by heart and vascular researchers at Johns Hopkins.
Johns Hopkins Children’s Center scientists have found that having a regular outpatient mental health provider may not be enough to prevent children and teens with behavioral problems from repeatedly ending up in the emergency room. The study is published in the June 1 issue of the journal Psychiatric Services.
Surprising’ finding shows no impact of presumed surgeon fatigue at night
Despite concerns that surgeon fatigue is leading to dangerous complications for patients and data showing worse outcomes for many patients who undergo surgery at night, new Johns Hopkins research suggests that — in the case of heart and lung transplants — time of day has no affect on patient survival.

Work in flies and mice has implications for regeneration therapies
Johns Hopkins scientists have discovered how two closely related proteins guide projections from nerve cells with exquisite accuracy, alternately attracting and repelling these axons as they navigate the most miniscule and frenetic niches of the nervous system to make remarkably precise connections.
Older, sicker heart-transplant recipients are significantly more likely to be alive a year after their operations if they have their transplants at hospitals that do a large number of them annually, new Johns Hopkins research suggests. These patients fare less well at low-volume centers, the research shows.
Study shows need for judicious use of drugs to curb antibiotic resistance
Short courses of antibiotics appear just as effective as longer ones — and a great deal safer — in treating respiratory infections that might cause pneumonia in children on temporary breathing devices, according to a Johns Hopkins Children’s Center study published online May 3 in Clinical Infectious Diseases.
Chicago-based publications Becker’s Hospital Review and its Ambulatory Surgery Center Review have named The Johns Hopkins Hospital as one of the 100 best places to work in health care in the United States for 2011. Johns Hopkins also made Becker’s listing in 2010.
Johns Hopkins researchers transform inert white fat into brown fat to burn off calories and weight
By knocking down the expression of a protein in rat brains known to stimulate eating, Johns Hopkins researchers say they not only reduced the animals' calorie intake and weight, but also transformed their fat into a type that burns off more energy. The finding could lead to better obesity treatments for humans, the scientists report.
A small Johns Hopkins Children’s Center study of children and teens with cystic fibrosis (CF) shows that simple exercise, individually tailored to each patient’s preference and lifestyle, can help improve lung function and overall fitness. The findings were reported on May 3 at the 2011 annual meeting of Pediatric Academic Societies in Denver, Colo.
Young black men who have sex with men (MSM) get infected with HIV nearly five times more often than MSM from other races, even though they don’t have more unprotected sex.

Pediatricians from Johns Hopkins Children’s Center and elsewhere have discovered a link between low levels of vitamin D and anemia in children. The findings, presented on May 1 at the annual meeting of the Pediatric Academic Societies in Denver, Colo., show that vitamin D deficiency may play an important role in anemia.
Scientists at Johns Hopkins have shown in laboratory experiments in mice that blocking the action of a signaling protein deep inside the heart’s muscle cells blunts the most serious ill effects of high blood pressure on the heart. These include heart muscle enlargement, scar tissue formation and loss of blood vessel growth.
Even mild blast exposure damages nerve cells in mice, study shows
Stronger and tougher body armor to shield the chest, abdomen and back may be just what soldiers fighting in the Afghanistan and Iraq wars need to better protect their brains from mild injuries tied to so-called “shell shock,” results of a Johns Hopkins study in mice suggests. Such mild trauma, resulting from the initial shock of exploding mines, grenades and improvised explosive devices (IEDs) now accounts for more than 80 percent of all brain injuries among U.S. troops. Some 160,000 American veteran men and women are estimated to have sustained this kind of trauma.
Hospitals and physician practices that form care-coordinating networks called "Accountable Care Organizations (ACOs)," under provisions of the new health-care law could reap cost-savings and other benefits. Experts at Johns Hopkins and the University of Pennsylvania warn, however, that such networks could potentially be designed to exclude minorities and widen disparities in health care.

The process may also be involved in learning and memory, the researchers say.
Work in mice has implications for treating autism, post-traumatic stress
Researchers at Johns Hopkins have discovered in mice a molecular wrecking ball that powers the demolition phase of a cycle that occurs at synapses -- those specialized connections between nerve cells in the brain -- and whose activity appears critical for both limiting and enhancing learning and memory.The newly revealed protein, which the researchers named thorase after Thor, the Norse god of thunder, belongs to a large family of enzymes that energize not only neurological construction jobs but also deconstruction projects.
Compounds helped nerve extensions re-grow faster in mouse studies
Drugs already in development to treat Alzheimer’s disease may eventually be tapped for a different purpose altogether: re-growing the ends of injured nerves to relieve pain and paralysis. According to a new Johns Hopkins study, experimental compounds originally designed to combat a protein that builds up in Alzheimer’s-addled brains appear to make crushed or cut nerve endings grow back significantly faster, a potential boon for those who suffer from neuropathies or traumatic injuries.
A Johns Hopkins study of 769 men from across the United States recently diagnosed with low-grade prostate cancer shows that forgoing immediate surgery to remove the tumor or radiation poses no added risk of death. Delaying treatment is fine, the results show, so long as the cancer’s progression and tumor growth are closely monitored through “active surveillance” and there is no dramatic worsening of the disease over time.
