Agricultural pesticides raise risk of autism in unborn children

Pregnant women who lived in close proximity to fields and farms where chemical pesticides were applied experienced a two-thirds increased risk of having a child with autism spectrum disorder or other developmental delay, a study by researchers with the UC Davis MIND Institute has found. The associations were stronger when the exposures occurred during the second and third trimesters of the women's pregnancies.

Long-term care for soaring numbers of people with dementia need to be improved, says new RAND study

As millions of Americans struggle to help loved ones with dementia, policymakers should consider more ways to improve long-term services and supports for the soaring numbers of people with the debilitating condition and their caregivers, a new RAND Corporation study says -- and it offers possible ways to do so.

Overlooked DNA shuffling drives deadly paediatric brain tumour

One of the deadliest forms of paediatric brain tumour, Group 3 medulloblastoma, is linked to a variety of large-scale DNA rearrangements which all have the same overall effect on specific genes located on different chromosomes.

Bisexual men are vulnerable to STIs and other health problems

Bisexual men have many unmet public health needs, which leave them vulnerable to sexually transmitted infections (STIs) and other health problems. This new study from the Centers for Disease Control and Prevention (CDC) illuminates the behavioral, interpersonal, and social realities of men who have sex with men and women (MSMW), and it explores possible interventions to better serve their needs.

Six-gene signature predicts survival after targeted therapy for NSCLC

The presence of a six-gene profile in the microRNA of patients with advanced non-squamous non-small-cell lung cancer predicts reduced survival likelihood after first-line treatment with targeted therapy followed by chemotherapy for disease progression, indicate research results.

FGFR1 amplification predicts poor outcome in early-stage NSCLC

Amplification of fibroblast growth factor receptor 1 is associated with poor clinical outcome in patients with early-stage non-small-cell lung cancer, Swiss researchers report.

SCLC tumours replicated in mice from patients' CTCs

Scientists have used circulating tumour cells taken from patients with small-cell lung cancer to grow explant tumours in mice that retain the original’s morphological and genetic characteristics.

Greenlander study identifies single mutation with large diabetes risk

Researchers have used a Greenlandic cohort to identify a genetic mutation whose effect on the risk of diabetes is “several times larger” than any previously discovered.

Telephone-based weight loss intervention is effective in breast cancer treatments

A series of simple telephone calls can make a profound difference in helping women to meet their treatment goals for breast cancer, according to a randomized trial of women who are also obese, published online today in Journal of Clinical Oncology by Dr. Pamela Goodwin of Mount Sinai Hospital and the Lunenfeld-Tanenbaum Research Institute.

UCLA study sheds light on the development of lung cancer

UCLA researchers led by Dr. Brigitte Gomperts have discovered the inner workings of the process thought to be the first stage in the development of lung cancer. Their study explains how factors that regulate the growth of adult stem cells that repair tissue in the lungs can lead to the formation of precancerous lesions.

HIV infection emerges among PWID in the Middle East and North Africa

HIV epidemics are emerging among people who inject drugs in several countries in the Middle East and North Africa. Though HIV infection levels were historically very low in the Middle East and North Africa, substantial levels of HIV transmission and emerging HIV epidemics have been documented among people who inject drugs in at least one-third of the countries of this region, according to findings published today in PLOS Medicine.
