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.
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.
An analysis of data on heart and lung transplant recipients indicates that patients who had transplant surgery performed at nighttime did not have a significantly different rate of survival up to one year after organ transplantation, according to a study in the June 1 issue of JAMA.
Use of established fracture prediction methods in older patients with type 2 diabetes mellitus (DM) found that scores from these methods were associated with hip and nonspine fracture risk, and a certain score associated with higher risk of fracture compared to persons without DM, according to a study in the June 1 issue of JAMA. Because patients with type 2 DM often have higher levels of bone mineral density (BMD), it has been uncertain the applicability of fracture risk screening methods typically used for patients with lower levels of BMD.
Frequently cited studies involving associations of biomarkers report effect sizes that are often larger when compared to summary estimates from meta-analyses evaluating the same associations, according to a study in the June 1 issue of JAMA.

A gynecologist and a molecular biologist have collaborated to show for the first time that pelvic organ prolapse – a condition in which the uterus, bladder or vagina protrude from the body – is caused by a combination of a loss of elasticity and a breakdown of proteins in the vaginal wall.
African-Americans who have multiple sclerosis (MS) have lower vitamin D levels than African-Americans who don’t have the disease, according to a study published in the May 24, 2011, print issue of Neurology®, the medical journal of the American Academy of Neurology. However, most of the difference in vitamin D levels was due to differences in climate and geography.
Coronary computed tomographic (CT) angiography, which can detect plaque buildup in heart vessels, is sometimes used as a screening tool to assess the risk for a heart attack. However, the usefulness of the test on low-risk patients who do not have coronary symptoms, such as chest pain, has been unclear. In the first large population study to assess the impact of the test on physicians and patients, Johns Hopkins cardiologists found that having CT angiography leads to more prescriptions for cholesterol-lowering medications and aspirin, as well as more stress tests, nuclear medicine scans and invasive catheterizations. However, the incidence of heart attacks or cardiac death among people in the study was the same, whether or not patients had a CT angiography test.
The number of young adults in the U.S. with high blood pressure may be much higher than previously reported. A new study analyzed data on more than 14,000 people between 24 and 32 years old. Nineteen percent had elevated blood pressure. The findings illustrate how the processes that trigger serious chronic illnesses in older adults may begin early in life.
