The largest randomised trial of ovarian cancer screening has shown that both the CA125 blood test and transvaginal ultrasound screening strategies are capable of detecting early stage ovarian cancers. The study detected almost half of all cancers in stage I/II, with a significant improvement in specificity for multimodal screening.
A study published in PLoS Medicine found that children of older fathers tend to perform poorly in intelligence tests during infancy and early childhood. In contrast, the same children who have older mothers exhibit better cognitive skills. The researchers suggest genetic and social factors as possible explanations for this association.
Research from Tel Aviv University found that people with type 2 diabetes are 1.5 times more likely to experience cognitive decline and 1.6 times more likely to suffer from dementia than those without the condition. Higher blood glucose levels may contribute to this relationship.
A recent study found that older adults who consume moderate amounts of alcohol perform worse on cognitive tests than their younger counterparts, despite similar blood alcohol levels. The researchers suggest that this is due to factors other than age-related declines in cognitive skills, such as changes in how alcohol affects individuals.
A commonly used questionnaire for measuring quality of life in ADPKD patients is not sensitive enough to detect physical and mental problems. The study found links between patient characteristics and physical scores, but no significant difference in quality of life scores compared to the general population.

Researchers from the University of Leicester and British Geological Survey have devised a method to identify levels of environmental arsenic by testing toenail clippings. They found elevated levels of arsenic in people living close to a former arsenic mine, but more research is needed to confirm potential health risks.
A Johns Hopkins study found that older men with PSA levels less than 3 nanograms per milliliter are unlikely to die of or experience aggressive prostate cancer. This suggests that routine PSA testing may be unnecessary for some older men, potentially reducing costs and morbidity.
Research suggests that discontinuing routine PSA screening in elderly men (75+ years old) with low PSA levels may not increase undetected lethal disease rates. Instead, it could avoid unnecessary treatments and reduce diagnostic costs. Men over 75 with PSA < 3ng/ml have a low risk of developing high-risk prostate cancer.
Researchers at Uppsala University have developed a model to calculate the appropriate dose of Waran before treatment starts. The study used data from 5,700 subjects across four regions to identify two genes, VKORC1 and CYP2C9, which can predict dosage needs for patients of European, African, and Asian origin.
