Increasing height and body mass index linked to ovarian cancer risk
Increasing height and, among women who have never taken menopausal hormone therapy, increased body mass index are risk factors for developing ovarian cancer in women, revealed by researchers.

Working overtime work may lead to depression
People who work 11 hours are twice as likely to suffer depression. In simple words, too much overtime or working long hours doubles your depression odds, confirmed in recently published scientific study. Workers who spend long hours at the office are more than twice as likely to develop depression as those who do a standard day.

Reducing drug funding to Medicare patients raises questions
The lack of financial assistance to cover the cost of drugs to Medicare beneficiaries could result in an additional 18,000 patients discontinuing one or more prescriptions for essential drugs a year and others to not take their required medications regularly.

HAART found effective for treating HIV infected children
This observational cohort study, by Andrew Edmonds and colleagues, reports that treatment with highly active antiretroviral therapy (HAART) markedly improves the survival of HIV-infected children in Kinshasa, DRC, a resource-deprived setting. The findings presented suggest that HAART is as effective for improving the survival of HIV-infected children in a severely resource-deprived country (still recovering from civil war) as in more resource-privileged settings.

Blood pressure changes are age related but important for health
The main causes of increases in blood pressure over a lifetime are modifiable and could be targeted to help prevent cardiovascular disease: although high blood pressure sometimes has no obvious symptoms, this condition, which affects about a third of the adult UK and US populations, can lead to life-threatening heart attacks and stroke, so reducing blood pressure is very important for health.

Medical complicity in torture at Guantánamo Bay
Inspection of medical records, case files, and legal affidavits provides compelling evidence that medical personnel who treated detainees at Guantánamo Bay (GTMO) failed to inquire and/or document causes of physical injuries and psychological symptoms they observed in the detainees, according to a paper published this week in PLoS Medicine.

Physical activity can reduce genetic predisposition to obesity
Although the whole population can benefit from a physically active lifestyle, in part through reduced obesity risk, a new study shows that individuals with a genetic predisposition to obesity can benefit even more.

Replacing saturated fat with PUFA is good for the heart
The replacement of dietary saturated fatty acids with polyunsaturated fatty acids reduces coronary heart disease events, bringing much needed scientific evidence to an issue debated by experts and clinical guidelines.

125.2 million pregnant women at risk of malaria
Research published this week in PLoS Medicine concludes that at least 125.2 million women at risk of malaria become pregnant each year.

Hospital superbug MRSA diffused by patients
A new study finds that methicillin-resistant Staphylococcus aureus (MRSA) –responsible for several difficult-to-treat infections including blood poisoning and pneumonia and a particular problem in hospitals – occurs in distinct geographical clusters across Europe, indicating that MRSA is being diffused by patients moving between hospitals rather than spreading freely in the community.

Oldest evidence of leprosy found in India
A biological anthropologist from Appalachian State University working with an undergraduate student from Appalachian, an evolutionary biologist from UNC Greensboro, and a team of archaeologists from Deccan College (Pune, India) recently reported analysis of a 4000-year-old skeleton from India bearing evidence of leprosy.

Humans driving increased dengue risk in Australia
Drought-proofing Australia's urban regions by installing large domestic water tanks may enable the dengue mosquito Aedes aegypti to regain its foothold across the country and expand its range of possible infections, according to a new study published May 5 in the open-access journal PLoS Neglected Tropical Diseases.

First time mothers at a risk of psychosis after childbirth
A study of risk factors associated with psychotic illness after childbirth, published this week in the open-access journal PLoS Medicine, shows that first-time mothers are at the greatest risk of developing psychosis in the month following the birth of their child – even if they have never been treated in hospital for mental illness in the past.

Multiple sclerosis linked to vitamin D deficiency during pregnancy
Researchers have found evidence that a direct interaction between vitamin D and a common genetic variant alters the risk of developing multiple sclerosis (MS).

NPY gene variation may lead to early heart disease
Researchers from Duke University Medical Center have identified a variation in a particular gene that increases susceptibility to early coronary artery disease.
