Early menopause affects 1 in 14 women aged 30 to 49 living in low and middle income countries, finds a pooled data analysis of its prevalence in 44 nations published in the open access journal BMJ Global Health. The incidence is consistently higher in rural areas than it is in urban areas across all regions and countries included in the analysis, but education and delayed childbearing strongly minimise the risk.

Two in five women with ovarian cancer are diagnosed only after an emergency hospital admission, when they are 3 times less likely to have early stage and potentially curable disease, finds a data analysis published in the open access journal BMJ Oncology. And rates of diagnosis after an emergency admission are even higher among women who are young, old, frail, or who live in areas of deprivation, the findings indicate.

A major new study, published today in The Lancet Diabetes & Endocrinology has shown that cortisol levels in patients with adrenal tumors are far less stable than previously assumed.

A molecular imaging technology developed by Prof. Shai Rahimipour of Bar-Ilan University is helping scientists uncover one of the earliest and most elusive drivers of Alzheimer's disease, opening new possibilities for earlier diagnosis and more precise treatment.

The technology played a central role in a new international study published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association, led by researchers at the Icahn School of Medicine at Mount Sinai in New York together with collaborators from Bar-Ilan University and Canada. The study provides compelling evidence that soluble amyloid-beta oligomers -- tiny toxic protein aggregates believed to trigger Alzheimer's disease years before symptoms appear -- can damage brain cells long before they become detectable by today's diagnostic methods.
