No increased risk of suicide in patients using smoking cessation drugs

Posted: 10 Oct 2013 05:53 PM PDT

A study to assess whether patients prescribed smoking cessation drugs are at an increased risk of suicide, self-harm and treated depression compared with users of nicotine replacement therapy has found no evidence of an increased risk.

Suicidal talk on Twitter mirrors state suicide rates

Posted: 10 Oct 2013 07:51 AM PDT

Effects of soy, whey protein supplementation post-exercise

Posted: 10 Oct 2013 06:15 AM PDT

A group of researchers recently expanded upon the limited prior research examining the effects of soy and whey protein supplementation on testosterone, sex hormone binding globulin (SHBG), and cortisol responses to an acute bout of resistance exercise.

Maintenance mechanism prevents stem cells from aging

Posted: 10 Oct 2013 06:15 AM PDT

Action is needed now to lower the content of aluminium in infant formulas

New research shows that infant formulas are still heavily contaminated with aluminium.

Mobility limitation due to a lack of confidence in balance

Posted: 10 Oct 2013 06:14 AM PDT

A fall and subsequent injury decreases a person's balance confidence and increases his or her fear of falling. People aged over 60 years who had sustained a hip fracture and had a lower sense of balance confidence, also experienced difficulty in walking outdoors and climbing stairs. In addition, compared to those with higher balance confidence, they perform less well in walking and balance tests.

Weight loss through use of intestinal barrier sleeves

Posted: 10 Oct 2013 06:12 AM PDT

Scientists have discovered that the placement of a non-permeable tube in the small intestine leads to reduced nutrient absorption and consequently to reduced obesity and enhanced glucose metabolism.

Depression in newly diagnosed Parkinson's disease patients linked to reduced striatal dopamine synthesis

Posted: 10 Oct 2013 06:12 AM PDT

Up to 60% of individuals with Parkinson's disease (PD) exhibit mild to moderate depression, which is often underdiagnosed. It is unclear whether depression results from having a debilitating disease or reflects a parallel abnormal change in the brain caused by PD pathophysiology.

Insulin 'still produced' in most people with type 1 diabetes

Posted: 09 Oct 2013 06:38 PM PDT

New technology has enabled scientists to prove that most people with type 1 diabetes have active beta cells, the specialized insulin-making cells found in the pancreas. Type 1 diabetes occurs when the body's immune system destroys the cells making insulin, the substance that enables glucose in the blood to gain access to the body's cells.

Spinning-disk microscope offers window into the center of cell

Posted: 09 Oct 2013 06:38 PM PDT

A new method of imaging cells is allowing scientists to see tiny structures inside the "control center" of the cell for the first time.

40 years of federal nutrition research fatally flawed, study finds

Posted: 09 Oct 2013 05:10 PM PDT

Four decades of nutrition research funded by the Centers for Disease Control and Prevention (CDC) may be invalid because the method used to collect the data was seriously flawed, according to a new study has demonstrated significant limitations in the measurement protocols used in the National Health and Nutrition Examination Survey, revealed that a majority of the nutrition data collected by the NHANES are not "physiologically credible."

Skill ratings predict which surgeons perform safer surgeries

Posted: 09 Oct 2013 05:10 PM PDT

Video ratings data of bariatric surgeons' operating skills successfully predicted whether patients would suffer complications after surgery.

Single gene mutation linked to diverse neurological disorders

Posted: 09 Oct 2013 05:10 PM PDT

A research team says a gene mutation that causes a rare but devastating neurological disorder known as Lesch-Nyhan syndrome appears to offer clues to the developmental and neuronal defects found in other, diverse neurological disorders like Alzheimer's, Parkinson's and Huntington's diseases.

Steps to reduce risk of harm to potentially normal pregnancies

Posted: 09 Oct 2013 05:10 PM PDT

A panel of 15 medical experts from the fields of radiology, obstetrics-gynecology and emergency medicine has recommended new criteria for use of ultrasonography in determining when a first trimester pregnancy is nonviable (has no chance of progressing and resulting in a live-born baby). These new diagnostic thresholds would help to avoid the possibility of physicians causing inadvertent harm to a potentially normal pregnancy.

Potential topical treatment for macular degeneration

Posted: 09 Oct 2013 05:10 PM PDT

Researchers have identified a possible topical treatment for age-related macular degeneration (AMD). The findings are the first to report successful topical use of a compound with the potential to treat both major forms of AMD, which can currently only be treated in later stages with regular injections into the eye.

Likely culprit behind liver problems linked to intravenous feeding

Posted: 09 Oct 2013 01:27 PM PDT

Researchers know that feeding some patients intravenously can save their lives -- but also can cause liver damage. Now scientists have figured out the likely culprit, one of the ingredients in intravenous food, behind the liver problems.

New technique allows anti-breast cancer drugs to cross blood-brain barrier

Posted: 09 Oct 2013 01:27 PM PDT

Some breast cancer drugs can penetrate the blood-brain barrier (BBB), but they have not been very effective against brain metastases, whereas other, more effective anti-breast cancer drugs cannot penetrate the BBB at all. Researchers have now used a new approach to selectively permeabilize the BBB at sites of brain metastases, even those 200 times smaller than currently detectable in the clinic.

Whites more prone to certain heart condition than other ethnic groups

Posted: 09 Oct 2013 01:27 PM PDT

An individual's race or ethnic background could be a determining factor when it comes to risk of atrial fibrillation, the most frequently diagnosed type of irregular heart rhythm.

New study quantifies psychological damage of stalking

Posted: 09 Oct 2013 01:26 PM PDT

A study has concluded that women who are the victims of stalking are two to three times more likely to suffer from psychological distress than those with similar characteristics who have never been stalked.

Stroke may shave three out of five quality years off life

Posted: 09 Oct 2013 01:26 PM PDT

Stroke treatments and prevention to improve quality of life for people who experience a stroke is poorer than researchers hoped, with stroke still taking nearly three out of five quality years off a person's life, according to a new study. Researchers say the findings leave considerable room for improvement in stroke treatment.

Big data reaps big rewards in drug safety

Posted: 09 Oct 2013 11:15 AM PDT

Using the Food and Drug Administration's Adverse Event Reporting System (FAERS), a hospital electronic health records database, and an animal model, a team of researchers report that by adding a second drug to the diabetes drug rosiglitazone, adverse events dropped enormously. That suggests that drugs could be repurposed to improve drug safety, including lowering the risk of heart attacks.

Trauma-related psychophysiologic reactivity identified as best predictor of PTSD

Posted: 09 Oct 2013 10:32 AM PDT

Researchers have determined that psychophysiologic reactivity to trauma-related, script-driven imagery procedures is a promising biological predictor of a post-traumatic stress disorder diagnosis.

Causes, treatment strategies for systemic scleroderma

Posted: 09 Oct 2013 10:32 AM PDT

Using mice, lab-grown cells and clues from a related disorder, researchers have greatly increased understanding of the causes of systemic sclerosis, showing that a critical culprit is a defect in the way certain cells communicate with their structural scaffolding. They say the new insights point the way toward potentially developing drugs for the disease, which affects approximately 100,000 people in the United States.

Drugs fail to meet hormone targets in control of rare growth disorder

Posted: 09 Oct 2013 10:30 AM PDT

Over a quarter of UK patients treated for growth hormone-producing tumours do not achieve 'safe' growth hormone (GH) levels, according to a 30 year UK multi-centre study of clinical management of the rare disease acromegaly. The findings show that drugs to control acromegaly often fail to bring the disease completely under control in routine clinical practice.
