Computational quantification of brain perivascular space morphologies: associations with vascular risk factors and white matter hyperintensities. A study in the Lothian Birth Cohort 1936: Perivascular spaces associations

ConclusionsComputational measures reflecting individual PVS size, length and width were more strongly associated with WMH, stroke and hypertension than computational count or visual PVS score. Multidimensional computational PVS metrics may increase sensitivity to detect associations of PVS with risk exposures, brain lesions and neurological disease, provide greater anatomic detail and accelerate sunderstanding of disorders of brain fluid and waste clearance.Graphical abstract

Authors: Khan AA, Thomas GN, Lip GYH, Shantsila A Abstract Atrial fibrillation is the most common heart arrhythmia and is associated with poor outcomes. The adverse effects of atrial fibrillation are mediated through multiple pathways, including endothelial dysfunction, as measured by flow-mediated dilatation. Flow-mediated dilatation has demonstrated endothelial dysfunction in several conditions and is associated with poor outcomes including mortality, yet can be improved with medical therapy. It is thus a useful tool in assessing endothelial function in patients.Endothelial dysfunction is present in patients with...

This study presents the effects of berberine (BBR) on the aging process resulting in a promising extension of lifespan in model organisms. BBR extended the replicative lifespan, improved the morphology, and boosted rejuvenation markers of replicative senescence in human fetal lung diploid fibroblasts. BBR also rescued senescent cells with late population doubling (PD). Furthermore, the senescence-associated β-galactosidase (SA-β-gal)-positive cell rates of late PD cells grown in the BBR-containing medium were ~72% lower than those of control cells, and its morphology resembled that of young cells. Mechanistically...

This study shows that CA are released from periventricular and subpial regions to the cerebrospinal fluid and are present in the cervical lymph nodes, into which cerebrospinal fluid drains through the meningeal lymphatic system. We also show that CA can be phagocytosed by macrophages. We conclude that CA can act as containers that remove waste products from the brain and may be involved in a mechanism that cleans the brain. Moreover, we postulate that CA may contribute in some autoimmune brain diseases, exporting brain substances that interact with the immune system, and hypothesize that CA may contain brain markers that m...

AliveCor is close to our hearts. Literally. David Albert, the co-founder of the company, started experimenting with handheld, wireless ECG devices in the late 90s. Approximately 10 years later we tried out their FDA-cleared, medical grade gadget. It was a truly inspiring moment. Needless to say, we’ve been keeping track of their journey ever since. In our eyes Kardia is the textbook example of technology shaping health care, empowering and supporting not only e-patients, but medical professionals as well. So, let’s take a look at their newest creation, the KardiaMobile6L! Why did the chicken cross the ro...

It’s fairly established medical science that people who have had heart attacks can take regular low doses of aspirin to significantly lower their risk of having another heart attack, or other heart problems including stroke. But it is still an open question whether or not people who haven’t had a heart event, but are at higher risk of one (because, for example) they have diabetes, high blood pressure, or elevated cholesterol levels), can also benefit from the over-the-counter painkiller and anti-inflammatory drug. A new study, published in the Journal of the American Heart Association, adds to that debate by ad...

CONCLUSIONS: Health-promotion interventions in the community pharmacy context probably improve pharmacy workers' behaviour and probably have a slight beneficial effect on health-related behaviour, intermediate clinical outcomes, and quality of life for pharmacy users. Such interventions are likely to be cost-effective and the effects are seen across a range of clinical conditions and health-related behaviours. Nevertheless the magnitude of the effects varies between conditions, and more effective interventions might be developed if greater consideration were given to the theoretical basis of the intervention and mechanisms...

AbstractIntroductionThe main objective of this research was to evaluate the association of insulin resistance (IR) with micro- and macrovascular complications, sex hormones, and other clinical data.MethodsCross-sectional study of patients older than 18  years old with type 1 diabetes mellitus (T1DM) was performed. Participants filled in questionnaires about T1D, disease duration, smoking, glycemic control, chronic diabetes complications, and hypertension status. Data about chronic diabetic complications (neuropathy, retinopathy, and nephropathy) were collected from medical records. History of major cardiovascular even...

After a stroke, the main goal is to get back home and be as independent as possible. To achieve that goal, most stroke rehabilitation centers focus on helping people to regain lost function, such as the inability to use a hand, to speak, to swallow, or to walk. A great deal of effort is put into functional recovery so that the patient can go home safely and adequately perform activities of daily living (ADLs). There is little effort put into aerobic exercise and conditioning in most stroke rehabilitation programs. A recent systematic review and meta-analysis published in the Journal of the American Heart Association (JAHA)...
