Stroke doubles dementia risk, concludes large-scale study

(University of Exeter) The study analyzed data on stroke and dementia risk from 3.2 million people across the world. The link between stroke and dementia persisted even after taking into account other dementia risk factors such as blood pressure, diabetes and cardiovascular disease. Their findings give the strongest evidence to date that having a stroke significantly increases the risk of dementia.

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...

AbstractAndrogens affect the cerebral vasculature and may contribute to sex differences in cerebrovascular diseases. Men are at a greater risk for stroke and vascular contributions to cognitive impairment and dementia (VCID) compared to women throughout much of the lifespan. The cerebral vasculature is a target for direct androgen actions, as it expresses several sex steroid receptors and metabolizing enzymes. Androgens ’ actions on the cerebral vasculature are complex, as they have been shown to have both protective and detrimental effects, depending on factors such as age, dose, and disease state. When administered...

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 (...

In a press briefing on June 25, Dr. Robert Redfield, director of the U.S. Centers for Disease Control and Prevention (CDC), said that the current official count of COVID-19 cases in the U.S. may actually be a drastic underestimate. Redfield said the new, much-higher estimate, is based on growing data from antibody testing, which picks up the presence of immune cells that react to SARS-CoV-2, the virus that causes COVID-19. People will test positive for antibodies to the virus if they have been infected—whether or not they ever got sick or even developed symptoms. Previously, testing was focused only on those with sym...

Conclusions Respiratory syncytial virus is highly infectious and can easily cause an outbreak in an LTCF. Polymerase chain reaction testing was contributory to identify cases rapidly. Rapid PCR results and intensified infection control measures were instrumental to halt the outbreak.

CONCLUSION: ICHRON predicted ChrD diagnosis at 3-years among an external, geographically distant validation cohort. These findings show the value of ICHRON for primary care patients in distinct locales. Additionally, electronic calculation of ICHRON empowers the clinical use of this tool to identify and differentially manage and treat high-risk patients.

This article will summarize the effects of more intensive blood pressure (BP) control on cardiovascular, cognitive, and renal outcomes among elderly (age ≥75 years) individuals at high risk for cardiovascular events. Subsets of patients who may not benefit and obstacles to implementation will be addressed. The authors’ insights will conclude the review. Recent findings A burst of new research regarding the effects of lower BP targets on cardiovascular, cognitive, and renal endpoints among the elderly has been published. Achieved values of 123 mmHg systolic in those without diabetes or prior stroke revealed st...
