Access to mental health care for teens improving, but less for communities with disparities

Wed, 27/05/2015 - 1:14pm
Teens in the U.S. have more availability of mental health care than they did two years ago, but access is not equal in all communities, new research suggests. A five year study gauged opportunities for children and teens at the local level in communities across the U.S. surveying over 2,000 adults across the U.S. who work and/or volunteer on behalf of children and teens.

Toddler temperament could be influenced by different types of gut bacteria

Wed, 27/05/2015 - 1:14pm
The microbiome of a toddler's gut may influence their behavior, a new study suggests. Scientists found correlations between temperament and the presence of specific types of intestinal bacteria in both girls and boys. The researchers aren't looking for a way to help parents modify the 'terrible twos,' but for clues about how - and where - chronic illnesses like obesity, asthma, allergies and bowel diseases start.

Seeing the action: Novel device images minute forces, actions involved in cell membrane hemifusion

Wed, 27/05/2015 - 1:50am
Researchers have developed a novel device to image the minute forces and actions involved in cell membrane hemifusion. To capture real time data on the behavior of cell membranes during hemifusion, the researchers pressed together two supported lipid bilayers on the opposing surfaces of the SFA. These bilayers consisted of lipid domains -- collections of lipids that in non-fusion circumstances are organized in more or less regularly occurring or mixed arrangements within the cell membrane.

A chip placed under the skin for more precise medicine

Wed, 27/05/2015 - 1:50am
It's only a centimeter long, it's placed under your skin, it's powered by a patch on the surface of your skin and it communicates with your mobile phone. The new biosensor chip is capable of simultaneously monitoring the concentration of a number of molecules, such as glucose and cholesterol, and certain drugs.

Cocaine addiction, craving and relapse

Wed, 27/05/2015 - 1:50am
One of the major challenges of cocaine addiction is the high rate of relapse after periods of withdrawal and abstinence. But new research reveals that changes in our DNA during drug withdrawal may offer promising ways of developing more effective treatments for addiction. Withdrawal from drug use results in reprogramming of the genes in the brain that lead to addictive personality, say researchers.

Study links better 'good cholesterol' function with lower risk of later heart disease

Wed, 27/05/2015 - 1:50am
HDL, the 'good cholesterol' helps remove fat from artery walls, reversing the process that leads to heart disease. Yet recent drug trials and genetic studies suggest that pushing HDL levels higher doesn't reduce the risk of heart disease. Now, an epidemiological study shows that a person's HDL function -- the efficiency of HDL molecules at removing cholesterol -- may be a better measure of coronary heart disease risk and target for heart-protecting drugs.

Psychedelic drugs should be legally reclassified as they may benefit patients, experts say

Wed, 27/05/2015 - 1:50am
Legal restrictions imposed on medical use of psychedelic drugs, such as LSD and psilocybin (the compound found in 'magic' mushrooms), are making trials almost impossible and authorities should 'downgrade their unnecessarily restrictive class A, schedule 1 classification,' writes a psychiatrist.

Newer contraceptive pills linked to higher clot risks, study confirms

Wed, 27/05/2015 - 1:50am
New evidence to confirm the link between newer contraceptive pills and higher risk of serious blood clots (known as venous thromboembolism or VTE) has been provided by a new study. About 9% of women of reproductive age worldwide use oral contraceptives, rising to 18% of women in developed countries and 28% of women in the UK.

Drug treatment to prevent hip fracture is neither viable nor cost effective, experts say

Wed, 27/05/2015 - 1:50am
The current focus on drugs to prevent hip fractures is neither viable as a public health strategy nor cost effective, argue an international team of researchers.

Increasing dietary fiber reduces risk of developing diabetes

Wed, 27/05/2015 - 1:50am
Consuming greater quantities of dietary fiber reduces the risk of developing type 2 diabetes, new research confirms. Over 360 million people worldwide are estimated to be affected by diabetes, and this number is projected to increase to more than 550 million by 2030, with serious consequences for the health and economy of both developed and developing countries.

Investigational immunotherapy treatment shows durable response in patients with metastatic melanoma

Tue, 26/05/2015 - 9:19pm
Advanced-stage melanoma patients have significant improvement in durable response rate when treated with a genetically-modified form of a herpes virus, whose native form causes the common cold sore, new research shows.

Changing diagnosis codes will challenge emergency medicine

Tue, 26/05/2015 - 9:19pm
Emergency medicine faces special challenges during this fall's changeover in how medical diagnoses are coded. Nearly a quarter of all ER clinical encounters could pose difficulties, authors of a new report state.

Future vaccine may help lower blood pressure long-term

Tue, 26/05/2015 - 8:42pm
A DNA vaccine helped lower blood pressure for up to six months, reduced tissue damage to the heart and blood vessels associated with hypertension in rats, investigators report. If future research shows the vaccine is a viable treatment option in humans, it could improve high blood pressure levels.

Moderate drinking in later years may damage heart

Tue, 26/05/2015 - 8:42pm
Moderate to heavy alcohol intake later in life may be associated with subtle changes in the structure and efficiency of the heart. Women may be particularly vulnerable to negative cardiac effects of alcohol at moderate to higher levels of consumption.

Study identifies possible role for carbon monoxide in treating hemorrhagic stroke

Tue, 26/05/2015 - 8:41pm
Carbon monoxide is typically associated with brain injury and neurological symptoms. But a new study suggests that when administered in small, carefully controlled amounts, CO may actually protect the brain from damage following hemorrhagic stroke.

Supernovas help 'clean' galaxies

Tue, 26/05/2015 - 7:57pm
Astronomers have found that the black holes located at the cores of galaxies launch fountains of charged particles, which can stir up gas throughout the galaxy and temporarily interrupt star formation. But unless something intervenes, the gas will eventually cool and start forming stars again.
