Cerebrovascular mental stress reactivity is impaired in hypertension

Mental stress causes carotid artery dilation and increases brain blood flow. A series of ultrasound experiments, described in BioMed Central's open access journal Cardiovascular Ultrasound, also found that this dilatory reflex was absent in people with high blood pressure.

FDA approves Multaq tablets (dronedarone) to treat atrial fibrillation

The U.S. Food and Drug Administration has approved Multaq tablets (dronedarone) to help maintain normal heart rhythms in patients with a history of atrial fibrillation or atrial flutter (heart rhythm disorders). The drug is approved to be used in patients whose hearts have returned to normal rhythm or who will undergo drug or electric-shock treatment to restore a normal heart beat.

Brain malformations significantly associated with preterm birth

New research out of Wake Forest University School of Medicine provides for the first time a solid scientific answer for the long-standing question of whether there is an association between preterm birth and brain malformations.

New peripherally inserted central catheter mimics nature

A novel coating being used on a new peripherally inserted central catheter (PICC) from r4 Vascular mimics the cell layer found on natural tissue surfaces.

Researchers using microRNA to identify aggressive melanoma

Research at the University of Leicester will be breaking new ground in the search for a simple blood test that could tell whether a patient with melanoma has the condition in an aggressive form.

Newly discovered gene regulates balance of 'bad' cholesterol

In an article in Science, Noam Zelcer from the LACDR describes a previously unknown mechanism for regulating the amount of LDL cholesterol. This offers opportunities for supplementing and improving the effect of so-called statins: medicines that remove 'bad' cholesterol from the bloodstream.

Two studies on polycystic ovarian syndrome shed light on its causes and its effect on brothers of women with the condition

Researchers have found evidence that chronic disease in either a mother or father can create unfavourable conditions in the womb that are associated with the development of polycystic ovarian syndrome (PCOS) in daughters. In another study, researchers found that brothers of women with PCOS and insulin resistance are themselves at greater risk of developing insulin resistance or diabetes, suggesting that factors associated with the condition can be passed down to sons as well as daughters.

New pieces in the autism inheritance puzzle

Pieces in the complex autism inheritance puzzle are emerging in the latest study from a research team including geneticists from the University of Pennsylvania School of Medicine and The Children's Hospital of Philadelphia (CHOP). The study identified 27 different genetic regions where rare copy number variations - missing or extra copies of DNA segments - were found in the genes of children with autism spectrum disorders, but not in the healthy controls. The findings are published June 26 in the open-access journal PLoS Genetics.

Optimizing the start time of statin therapy for diabetics

Researchers from North Carolina State University and Mayo Clinic have developed a computer model that medical doctors can use to determine the best time to begin using statin therapy in diabetes patients to help prevent heart disease and stroke.

Prostate cancer: current evidence weighs against population screening

The recent release of two large randomized trials suggests that if there is a benefit of screening, it is, at best, small, says a new report in CA: A Cancer Journal for Clinicians.

Epigenetic modulation at birth - altered DNA-methylation in white blood cells after Caesarean section

Swedish researchers have discovered that babies born by Caesarean section experience changes to the DNA pool in their white blood cells, which could be connected to altered stress levels during this method of delivery, according to the July issue of Acta Paediatrica.

Review of endocrine disorders in the U.S.

A dogged review of the medical literature has produced what is believed to be the nation's first comprehensive estimate of the extent of dozens of endocrine disorders in the United States.

Gene expression differences could bring better classification and treatment of juvenile arthritis

Scientists have discovered gene expression differences that could lead to better ways to classify, predict outcome, and treat juvenile idiopathic arthritis (JIA). Eventually such findings could enable doctors to target more aggressive treatment to children at risk of more severe arthritis, while those likely to have milder disease could be spared the stronger treatments that carry a greater risk of side effects. The researchers were supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), a part of the National Institutes of Health.

Researchers test whether estrogen could improve outcomes after traumatic brain injury, shock

UT Southwestern Medical Center researchers are conducting two pilot clinical trials to determine whether a single, early dose of estrogen can improve survival and neurological outcomes after severe traumatic brain injury or traumatic hemorrhagic shock.

First baby born after new ovarian transplant technique

A new technique for transplanting the ovaries of women who have lost their fertility as a result of cancer treatment was outlined to the 25th annual conference of the European Society of Human Reproduction and Embryology today (Monday 29 June).

Study could help target new pancreatitis treatments

Pancreatitis is often a fatal condition, in which the pancreas digests itself and surrounding tissue. Scientists have previously found that alcohol can trigger the condition by combining with fatty acids in the pancreas, which leads to an excessive release of stored calcium ions. Once calcium ions enter cell fluid in the pancreas it activates digestive enzymes and damages the cells.

Kenya seeks support from PEPFAR to expand blood transfusion centers

Kenya's Medical Services Permanent Secretary James Ole Kiyiapi announced Thursday that the government is in negotiations with PEPFAR for support in building additional blood transfusion centers in the country, Capital News reports.

How ‘high carb’ foods cause heart attacks

It has been commonly known for a number of years that certain foods, such as white bread and corn flakes, are bad for cardiac health, but new research from Israeli scientists shows just how 'high carb' foods cause heart attacks.

Inhaled growth hormone safe for children deficient in this key protein

A multi-center clinical trial led by a Riley Hospital for Children endocrinologist has found that inhaled growth hormone (GH) is well tolerated by children with GH deficiency and that this easy-to-use method can, over a one-week period, safely deliver GH to the blood stream. In addition to having implications for those who need GH, this first pediatric study of administering it through the lungs may also help researchers interested in using this convenient method for effectively delivering other types of medications to children.
