Loss of olfactory function in elderly linked to increased risk of dementia

In a long-term study of about 3,000 adults (age 57-85); the researchers found that the elderly who could not identify four out of five common odors were more likely to develop dementia within five years. Among the tested individuals, 78% were normal (identified four of five odors), 14% could identify three, 5% could identify two, 2% could name just one, and one percent were not able to identify any. In a follow-up study for five years, researchers found that the individuals who could not identify a single smell were diagnosed with dementia. Around 80% of those who could identify only one or two also developed dementia, with a dose-dependent relationship between a degree of smell loss and incidence of dementia.

Gum disease linked to increased risk of heart problems, Study finds

Cardiac disease and fatty buildup are closely related to each other. But the new study led by the UConn researchers proposes that fatty molecules might come not only from our diet but also from the bacteria living in our mouth. The researchers carried a chemical analysis of atheroma collected from patients by a colleague at Hartford Hospital and found some strange lipids with a chemical signature not similar to lipids from animals. Instead, those lipids come from a specific family of bacteria. The study was published in the recent issue of the Journal of Lipid Research.

Family Members without CDKN2A Gene Mutation, at Higher Risk of Melanoma

A new study published in the journal Genetics in Medicine revealed that family members who do not carry the inherited mutation are at higher risk of melanoma, though it is a hereditary disorder. The condition is called as phenocopy, where the phenotype is altered because of risk-enhancing genes or environmental factors within the families. Such members should be advised to avoid sunburn and be aware of their skin changes.
