Study examines race-based differences in social support needs among breast cancer patients

In a Psycho-Oncology study of 28 women who were being treated for breast cancer and were participating in focus groups, White participants noted that having other breast cancer survivors in their support network was essential for meeting their social support needs. Black participants did not reference other breast cancer survivors as part of their networks, however. Notably, both White and […]

Do differences in gait predict the risk of developing depression in later life?

Older people who were newly diagnosed with depression had a slower walking speed and a shorter step length compared with those without depression in a recent Journal of the American Geriatrics Society study. Gait parameters and mental health both have significant impacts on functional status in later life. The study’s findings suggest that gait problems may represent a potentially modifiable […]

New study sheds light on community-based approach to diabetes prevention in Bangladesh

New research funded by the MRC highlights the success of a novel community-based approach to diabetes prevention in low and middle-income countries (LMICs). The scientists behind the research say their study is the largest worldwide to assess how to prevent diabetes in a general adult population of 125,000 people. Researchers at the UCL Institute for Global Health and the Diabetic […]

Genetic study of impulsiveness reveals associations with psychiatric disorders

Impulsiveness and substance use share a genetic basis, according to genome-wide association studies published in JNeurosci by academic and industry researchers. With more than 20,000 participants, the research represents the largest genetic analysis of impulsive personality traits to date. Dr. Abraham Palmer and colleagues compared genetic data with self-reported impulsive personality traits and history of drug experimentation from a large […]

Excess immune pruning of synapses in neural cells derived from patients with schizophrenia

A study led by Massachusetts General Hospital (MGH) investigators finds evidence that the process of synaptic pruning, a normal part of brain development during adolescence, is excessive in individuals with schizophrenia. While previous studies have found structural abnormalities in the brains of people with schizophrenia that suggested a role for abnormal synaptic pruning, this study—published in Nature Neuroscience – is […]

Suicide can’t be predicted by asking about suicidal thoughts, major Australian study shows

The majority of people who die by suicide deny having suicidal thoughts when asked by doctors in the weeks and months leading up to their death, a ground-breaking UNSW Sydney study has found. The research questions a widely held belief that suicide can be accurately predicted by psychiatrists and clinicians by assessing a patient’s risk, especially in the short-term. The […]

How the immune system protects us against bowel cancer

Researchers at Universitätsmedizin Berlin have discovered a protective mechanism which is used by the body to protect intestinal stem cells from turning cancerous. The body’s innate immune system was found to play a pivotal role in this regard. The researchers were able to demonstrate that, rather than having a purely defensive role, the immune system is crucial in maintaining a […]

How type 1 diabetes gradually destroys insulin production

Using the new Imaging Mass Cytometry method, researchers of UZH have investigated the pancreas of healthy organ donors and those with type 1 diabetes. The study shows that many beta cells, which normally produce insulin, are still present in the early stages of the disease, but look very different. These beta cells could potentially be rescued for the benefit of […]

An upbeat attitude might help prevent 2nd stroke

(HealthDay)—If you’ve had a stroke, a positive outlook might just help prevent another one, a new study suggests. Researchers found that when people felt they could protect themselves from a second stroke, they had lower blood pressure. High blood pressure is a significant risk factor for a recurrent stroke. “You can protect yourself against stroke by reducing your risk factors. […]

Chilling studies show cold weather could raise stroke risk

Overexertion with a snow shovel isn’t the only cardiovascular risk during the winter. When temperatures go down, the incidence of stroke—the country’s fifth-leading cause of death—appears to go up. “There have been a number of studies that have confirmed this in different parts of the world,” said Dr. Daniel Lackland, a professor of epidemiology and neurology at the Medical University […]
