A new national survey of more than 2,000 physicians across multiple specialties finds that physicians believe overtreatment is common and mostly perpetuated by fear of malpractice, as well as patient demand and some profit motives.

Today, M-1 Ventures announced the six startups selected to participate in an intense 16-week program in Baltimore designed to set emerging businesses in the connected health and fitness industry on a fast track to success. This accelerator program operates with the support of Johns Hopkins Technology Ventures, Plank Industries, the University of Maryland (through UM Ventures), Brown Advisory and the Abell Foundation.

Sleep apnea, left untreated for even a few days, can increase blood sugar and fat levels, stress hormones and blood pressure, according to a new study of sleeping subjects. A report of the study’s findings, published in the August issue of The Journal of Clinical Endocrinology & Metabolism, adds further support for the consistent use of continuous positive airway pressure (CPAP), a machine that increases air pressure in the throat to keep the airway open during sleep. 

Johns Hopkins researchers report the unexpected presence of a type of neuron in the brains of mice that appears to play a central role in promoting sleep by turning ‘off’ wake-promoting neurons. The newly identified brain cells, located in a part of the hypothalamus called the zona incerta, they say, could offer novel drug targets to treat sleep disorders, such as insomnia and narcolepsy, caused by the dysfunction of sleep-regulating neurons.

In a mouse study designed to understand how chronic inflammation in sinusitis damages the sense of smell, scientists at Johns Hopkins say they were surprised to learn that the regeneration of olfactory tissue requires some of the same inflammatory processes and chemicals that create injury and loss of smell in the first place.

Pacífica Salud recently renewed a 10-year affiliation agreement with Johns Hopkins Medicine International. Under the agreement, Johns Hopkins—a global leader in academic health care—will continue providing consulting services in the areas of clinical program and staff development, quality, and patient safety. The signing of the agreement culminates a milestone year for the renowned medical center in Panama, as Pacífica Salud breaks ground on the site where it plans to develop a new hospital in Costa del Este, Panama City, Panama.

A Johns Hopkins paleontologist and her collaborative team of scientists report they have clear evidence that the arrival of humans and subsequent human activity throughout the islands of the Caribbean were likely the primary causes of the extinction of native mammal species there.  The evidence, they say, highlights the need for urgent human intervention to protect the native mammal species still inhabiting the region. 

In a small study that scanned the brains of teenagers while exposing them to tempting “food cues,” researchers report that reduced activity in the brain’s “self-regulation” system may be an important early predictor of adult obesity.

Results of a yearlong study funded by the Patient-Centered Outcomes Research Institute (PCORI) with more than 900 nurses at The Johns Hopkins Hospital suggest that well-designed online education can decrease the rate of nonadministration of prescribed and necessary doses of blood thinners to prevent potentially lethal blood clots in hospitalized patients.

In a bid to detect cancers early and in a noninvasive way, scientists at the Johns Hopkins Kimmel Cancer Center report they have developed a test that spots tiny amounts of cancer-specific DNA in blood and have used it to accurately identify more than half of 138 people with relatively early-stage colorectal, breast, lung and ovarian cancers. The test, the scientists say, is novel in that it can distinguish between DNA shed from tumors and other altered DNA that can be mistaken for cancer biomarkers.

Researchers at the Johns Hopkins University School of Medicine and the Mayo Clinic have compiled peer-reviewed evidence and crafted a guideline designed to help physicians and medical centers stop the use of a widely ordered blood test that adds no value in evaluating patients with suspected heart attack.

In a study looking at brain scans of people with mild loss of thought and memory ability, Johns Hopkins researchers report evidence of lower levels of the serotonin transporter — a natural brain chemical that regulates mood, sleep and appetite.

Johns Hopkins Kimmel Cancer Center scientists report they have discovered a biochemical process that gives prostate cancer cells the almost unnatural ability to change their shape, squeeze into other organs and take root in other parts of the body. The scientists say their cell culture and mouse studies of the process, which involves a cancer-related protein called AIM1, suggest potential ways to intercept or reverse the ability of cancers to metastasize, or spread.

Radiocarbon dating of a fossilized leg bone from a Jamaican monkey called Xenothrix mcgregori suggests it may be the one of the most recent primate species anywhere in the world to become extinct, and it may solve a long-standing mystery about the cause of its demise. The short answer: human settlement of its island home.

Out of nearly 4,700 hospitals reviewed, The Johns Hopkins Hospital ranked #1 in Maryland and #3 in the nation in U.S. News & World Report’s 2017–18 Best Hospitals list. Thirteen specialties at The Johns Hopkins Hospital are now among the top 10 in the nation. Ten specialties are in the top five.

In a review of half a dozen published studies in which patients self-reported use of opioids prescribed to them after surgery, researchers at Johns Hopkins report that a substantial majority of patients used only some or none of the pills, and more than 90 percent failed to dispose of the leftovers in recommended ways.

A new study led by Johns Hopkins researchers suggests that testing for the presence of orthostatic hypotension, a form of low blood pressure, be performed within one minute of standing after a person has been lying down. Current guidelines recommend taking the measurement three minutes after a person stands up.
