An apple a day keeps the doctor away Posted: 17 Dec 2013 06:05 PM PST Prescribing an apple a day to all adults aged 50 and over would prevent or delay around 8,500 vascular deaths such as heart attacks and strokes every year in the UK -- similar to giving statins to everyone over 50 years who is not already taking them -- according to a study.

Experts discover whether it's better to be right or be happy Posted: 17 Dec 2013 06:05 PM PST Doctors see many couples who lead unnecessarily stressful lives by wanting to be right rather than happy.

Importance of food as key provider of vitamins and nutrients Posted: 17 Dec 2013 02:08 PM PST While dietary supplements can help some people meet their nutrition needs, eating a wide variety of nutrient-rich foods is the best way for most people to obtain the nutrients they need to be healthy and reduce their risk of chronic disease, according to the Academy of Nutrition and Dietetics.

Home-making post-disaster Posted: 17 Dec 2013 09:40 AM PST When it comes time to rebuild, victims of home-destruction are often given only the bare essentials and told to make do. That is nowhere near enough says recent Concordia University doctoral graduate, Devora Neumark. In a new paper published in Housing, Theory and Society she argues that a powerful way to overcome the traumas associated with domicide and reconstitute a sense of home is to engage in house-beautification practices.

Researchers discover mechanism controlling development of myelodysplastic syndromes Posted: 17 Dec 2013 09:38 AM PST Researchers have discovered a control mechanism that can trigger the development of myelodysplastic syndromes (MDS), a group of blood cancers. This finding may lead to therapies capable of preventing the progression of these diseases.

Study indicates oral garlic not useful in treating vaginal thrush Posted: 17 Dec 2013 07:46 AM PST In a world-first study, researchers have found garlic does not significantly reduce vaginal candida (thrush).

Study: Pay kids to eat fruits, vegetables Posted: 17 Dec 2013 07:46 AM PST Researchers observed three schools adjust to new school lunch standards that require a serving of fruits or vegetables on every student's tray -- whether the child intends to eat it or not. Students discarded 70 percent of the extra fruits and vegetables -- wasting about $3.8 million each day.

Brain neurons subtract images, use differences Posted: 17 Dec 2013 07:42 AM PST Ten million bits -- that's the information volume transmitted every second with every quick eye movement from the eye to the cerebrum. Researchers describe the way those data are processed by the primary visual cortex, the entry point for the visual information into the brain. Deploying novel optical imaging methods, they demonstrated that the brain does not always transmit the entire image information. Rather, it uses the differences between current and previously viewed images.

Research backs risk-reduction surgery for ovarian cancer Posted: 17 Dec 2013 07:42 AM PST A study backs preventative surgery to improve survival for women who are at greater risk of getting ovarian cancer and suggests it appears helpful for women at risk of getting breast cancer because of genetic faults.

Discovery of 'teen gene' could hold promise for combating severe mental illnesses Posted: 17 Dec 2013 07:42 AM PST Researchers have isolated a gene, DCC, which is responsible for dopamine connectivity in the medial prefrontal cortex during adolescence. Working with mice models, they have shown that dysfunction of this gene during adolescence has behavioral consequences which carry into adulthood.

Epidemic of escherichia coli infections traced to one strain of bacteria Posted: 17 Dec 2013 07:41 AM PST In the past decade, a single strain of Escherichia coli, or E. coli, has become the main cause of bacterial infections in women and the elderly by invading the bladder and kidneys, according to a new study.

Researchers show genetic overlap in schizophrenia, cognitive ability Posted: 17 Dec 2013 05:53 AM PST Investigators have discovered, for the first time, a direct evidence of a genetic overlap between schizophrenia and general cognitive ability.

Pain drugs used in prostate gland removal linked to cancer outcome, study finds Posted: 17 Dec 2013 05:53 AM PST The methods used to anesthetize prostate cancer patients and control pain when their prostate glands are surgically removed for adenocarcinoma may affect their long-term cancer outcomes, a study found.

Smoking changes our genes Posted: 17 Dec 2013 05:52 AM PST We inherit our genes from our parents at birth. Later in life the genetic material can be changed by epigenetic modifications, i.e. chemical alterations of the DNA the affect the activity of the genes. Such alterations are normally caused by aging, but can also result from environmental factors and lifestyle. New research findings show that smoking alters several genes that can be associated with health problems for smokers, such as increased risk for cancer and diabetes.

Self-worth boosts ability to overcome poverty Posted: 17 Dec 2013 05:50 AM PST For people in poverty, remembering better times – such as past success – improves brain functioning by several IQ points and increases their willingness to seek help from crucial aid services, a new study finds.

Ear acupuncture can help shed pounds Posted: 16 Dec 2013 05:40 PM PST Ear acupuncture can help shed the pounds, indicates a small study, recently published.

Teaching residents to provide cost-conscious care Posted: 16 Dec 2013 03:38 PM PST Despite a national consensus among policy makers and educators to train residents to be more conscious of the cost of care, less than 15 percent of internal medicine residency programs have a formal curriculum addressing it.

Regenerative medicine: New tool for transplanting stem cells Posted: 16 Dec 2013 03:36 PM PST Researchers have developed a specialized catheter for transplanting stem cells into the beating heart. The novel device includes a curved needle and graded openings along the needle shaft, allowing for increased distribution of cells. The result is maximized retention of stem cells to repair the heart.

Retinoblastoma dysfunction promotes pancreatic cancer cell growth, study shows Posted: 16 Dec 2013 12:49 PM PST Cancer researchers have discovered that a protein that normally suppresses tumors actually promotes the growth and spread of pancreatic cancer.

Health care costs steadily increase with body mass Posted: 16 Dec 2013 11:22 AM PST Researchers are giving people another reason to lose weight in the new year: obesity-related illnesses are expensive. According to a study published, health care costs increase in parallel with body mass measurements, even beginning at a recommended healthy weight.

Heavy marijuana users have abnormal brain structure, poor memory Posted: 16 Dec 2013 05:04 AM PST Teens who were heavy marijuana users had abnormal changes in their brains related to memory and performed poorly on memory tasks, reports a new study. The brain abnormalities and memory problems were observed in the subjects' early twenties, two years after they stopped smoking marijuana, possibly indicating long-term effects. Memory-related structures in their brains appeared to shrink. The younger drug abuse starts, the more abnormal the brain appeared. The marijuana-related brain abnormalities look similar to schizophrenia-related brain abnormalities.

Significant minority think doctors should help 'tired of living' elderly to die if that's their wish Posted: 14 Dec 2013 11:48 AM PST One in five people believes that doctors should be allowed to help the elderly who are not seriously ill, but who are tired of living, to die, if that is their stated wish, reveals research published.

Breakthrough could lead to protection from fatal infections Posted: 13 Dec 2013 10:55 AM PST Researchers have found a way to protect against what can be a fatal rickettsial infection.

New concerns over safety of common anesthetic Posted: 13 Dec 2013 10:53 AM PST Patients receiving the widely used anesthesia drug etomidate for surgery may be at increased risk or mortality and cardiovascular events, according to a study.

Younger, early breast cancer patients often undergo unnecessary staging, imaging procedures Posted: 13 Dec 2013 06:28 AM PST More than one third of younger, early stage breast cancer patients undergo unnecessary imaging procedures at the time of staging and diagnosis, according to research. Often, doctors think they're not being good to their patients if they don't do all they can. Yet there's been a shift in focus to doing what matters for the patient and what's proven to improve outcomes, rather than testing for the sake of testing.

A little exercise goes a long way to prevent disease in children Posted: 13 Dec 2013 06:28 AM PST Increased physical activity can improve children's overall metabolic health in just six weeks.
