With Stroke Comes Higher Dementia Risk: Study

The association between stroke and increased dementia risk remained even after other dementia risk factors such as blood pressure, diabetes and heart disease were taken into account, the researchers say.

This study showed an association between reduced REM and increased mortality, but it did not demonstrate the cause of the association. REM deprivation could independently contribute to the development of numerous other diseases. The results apply more clearly to older adults, given that the age groups studied averaged in the 50s and 70s. Short REM may also be a marker of a sick or aging brain; less REM sleep has already been tied to a greater risk of dementia. Overall, ensuring adequate REM sleep is important to protecting your long-term health. Getting better sleep in middle age and beyond Maintaining good sleep should re...

This study is the first to provide a direct link between this inflammation and plaque development - by way of IFITM3. Scientists know that the production of IFITM3 starts in response to activation of the immune system by invading viruses and bacteria. These observations, combined with the new findings that IFITM3 directly contributes to plaque formation, suggest that viral and bacterial infections could increase the risk of Alzheimer's disease development. Indeed, researchers found that the level of IFITM3 in human brain samples correlated with levels of certain viral infections as well as with gamma-secretase activ...

In conclusion, using a large cohort with rich health and DNA methylation data, we provide the first comparison of six major epigenetic measures of biological ageing with respect to their associations with leading causes of mortality and disease burden. DNAm GrimAge outperformed the other measures in its associations with disease data and associated clinical traits. This may suggest that predicting mortality, rather than age or homeostatic characteristics, may be more informative for common disease prediction. Thus, proteomic-based methods (as utilised by DNAm GrimAge) using large, physiologically diverse protein sets for p...

In this study, we sought to elucidate the role of VRK-1 in regulation of adult life span in C. elegans. We found that overexpression of VRK-1::GFP (green fluorescent protein), which was detected in the nuclei of cells in multiple somatic tissues, including the intestine, increased life span. Conversely, genetic inhibition of vrk-1 decreased life span. We further showed that vrk-1 was essential for the increased life span of mitochondrial respiratory mutants. We demonstrated that VRK-1 was responsible for increasing the level of active and phosphorylated form of AMPK, thus promoting longevity. A Fisetin Variant, C...

Abstract Previous epidemiological studies primarily examined the temperature-related mortality burden of all-cause or cardiovascular diseases (CVD) and respiratory diseases. However, evidence on the heat- and cold-attributable mortality burden from other specific causes is limited. This paper aimed to systematically examine the association of heat and cold with a comprehensive spectrum of plausible temperature-related diseases, and to estimate the mortality burdens attributable to heat and cold. In the time-series study of 11 cities in Jiangsu, China, distributed lag non-linear models were applied to estimate city...

In this study, we applied a well studied prediction model developed on data from five CpG sites, to increase the practicability of these tests. We have determined the biological age of the heart, specifically of the right atrium (RA) and left atrium (LA), and of peripheral blood leucocytes, by measuring the mitotic telomere length (TL) and the non-mitotic epigenetic age (DNAmAge). We found that DNAmAge, of both atrial tissues (RA and LA), was younger in respect to the chronological age (-12 years). Furthermore, no significant difference existed between RA and LA, suggesting that, although anatomically diverse and ex...

Have you ever spent the day in a city with such bad air pollution that when you blew your nose the mucus had a black tinge? Have you ever coughed as you breathed in diesel fumes from a passing bus and thought to yourself, “Well, that’s a year gone from my life”? Could it actually be true — that air pollution leads to an early death? The answer, in fact, is an unqualified yes. Air pollution causes heart disease, lung disease, and early death It has been known for some time that air pollution causes lung cancer, chronic obstructive pulmonary disease, emphysema, asthma, heart disease, and stroke. One r...

Abstract We investigated the relationship between urinary Alzheimer-associated neuronal thread protein (AD7c-NTP) levels and apolipoprotein epsilon 4 (ApoE ɛ4) alleles, as well as other factors that cause cognitive decline, in the cognitively normal population. We recruited 329 cognitively normal right-handed Han Chinese subjects who completed ApoE gene testing and urinary AD7c-NTP testing. There was no significant difference in urinary AD7c-NTP levels between the normal control and subjective cognitive decline groups. Urinary AD7c-NTP levels were significantly higher in subjects with ApoE ɛ3/4 and 4/4 [0.6074 (...
