Is increased myocardial triglyceride content associated with early changes in left ventricular function? A 1H-MRS and MRI strain study
ConclusionsPredicting MTGC remains a challenge in routine clinical practice, as only BMI independently correlates with increased MTGC. MTGC may play a role in LV dysfunction but does not appear to be involved in the development of subclinical strain abnormalities.

Inflammation May Be the Culprit Behind Our Deadliest Diseases
In the early days of my medical residency, I met a man whom we’ll call Jason. He arrived to our emergency room on a holiday, nonchalant yet amiable, and complained of mild chest pain. Jason was tall and trim, with a strong South Boston accent and fingertips still faintly stained from his last home-improvement project. He was only 45 years old, but he looked much younger. He didn’t smoke, barely drank alcohol, and his cholesterol levels had always been normal. No one in his family had a history of heart disease. He asked us if we could work quickly—he wanted to be home for dinner with his daughters. [time-...

Sex differences and risk factors in recurrent ischemic stroke
ConclusionHypertension and dyslipidemia were significant risk factors of recurrent ischemic stroke in both genders. Smoking and alcohol drinking were significant risk factors associated with ischemic stroke recurrence in males. Therefore, smoking cessation and alcohol abstinence are recommended after the first stroke to prevent recurrent ischemic stroke especially for males. Diabetes was a significant risk factor of ischemic stroke recurrence in females. More extensive studies are needed to understand the causal relationship of each factors with ischemic stroke recurrence according to sex differences and specification of p...

Differences in the choroid plexus volume and microstructure are associated with body adiposity
The choroid plexus (CP) is a cerebral structure located in the ventricles that functions in producing most of the brain’s cerebrospinal fluid (CSF) and transporting proteins and immune cells. Alterations in CP structure and function has been implicated in several pathologies including aging, multiple sclerosis, Alzheimer’s disease, and stroke. However, identification of changes in the CP remains poorly characterized in obesity, one of the main risk factors of neurodegeneration, including in the absence of frank central nervous system alterations. Our goal here was to characterize the association between obesity, measur...

Modern Treatment of Asymptomatic Carotid Stenosis —The Importance of Both Medical Therapy and Carotid Endarterectomy
Each year there are approximately 700  000 new ischemic strokes in the US, and 10% to 15% of them are caused by thromboembolism from a previously asymptomatic carotid stenosis (ACS). Three large randomized clinical trials, published in the 1990s and early 2000s, have demonstrated a significant benefit of carotid endarterectomy (CEA) i n preventing stroke in patients with severe ACS compared with medical therapy alone. They showed a 50% relative risk reduction in 5-year stroke rate and an approximately 1% per year absolute stroke risk reduction. Over the course of the past 2 decades, there has been significant improvement...

Assessment of Atrial Fibrosis and Its Implications in Atrial Fibrillation and Stroke
AbstractPurpose of reviewCardiac magnetic resonance imaging (CMRI) can be used to accurately define atrial fibrosis burden and is increasingly available, which has led to a renaissance in our understanding of atrial fibrosis as a major component of the atrial disease substrate. The purpose of this review is to provide information on our current understanding of atrial fibrosis and its relation to atrial fibrillation (AFib) and stroke, highlight its implications in the treatment of these conditions, and discuss potential therapies for atrial fibrosis.Recent findingsCMRI-defined atrial fibrosis has a proven utility in strati...

Alterations in Brain Network Organization in Adults With Obesity as Compared With Healthy-Weight Individuals and Seniors
Objective Life expectancy and obesity rates have drastically increased in recent years. An unhealthy weight is related to long-lasting medical disorders that might compromise the normal course of aging. The aim of the current study of brain connectivity patterns was to examine whether adults with obesity would show signs of premature aging, such as lower segregation, in large-scale networks. Methods Participants with obesity (n = 30, mean age = 32.8 ± 5.68 years) were compared with healthy-weight controls (n = 33, mean age = 30.9 ± 6.24 years) and senior participants who were stroke-free and without dementia (...

Sex-specific association of metabolic risk factors with brain ischemic lesions by severity and location
ConclusionsMetabolic syndrome was associated with brain ischemic lesions in men but not in women. Higher body mass index was related to ischemic lesions located in lobar in men and in deep brain/infratentorial areas in women. Its mechanisms remain to be further investigated.

Lifestyle Risk Factors and Findings on Brain Magnetic Resonance Imaging of Older Adult American Indians: The Strong Heart Study
Conclusions: This study found similar associations between smoking and vascular brain injury among American Indians, as seen in other populations. In particular, these findings support the role of smoking as a key correlate for cerebral atrophy.Neuroepidemiology

Editorial: Telomeres and Epigenetics in Endocrinology
This study was hypothesis-driven; the genetic variants were selected for being previously and substantially genotyped. The big sample size and the rich panel of other biomarkers allowed the authors to conduct much more detailed analyses on this topic. The third article by Provenzi et al. proposed their perspectives on the role of telomeres in premature birth and discussed the potential implications for early adversity and care in the neonatal intensive care unit (Pavanello et al.). Indeed, the speculation of telomeres in aging begins in the premature aging syndrome. It is thus interesting to examine if telomeres also play...

Shengui Sansheng San Ameliorates Cerebral Energy Deficiency via Citrate Cycle After Ischemic Stroke
Conclusion In summary, SSS extraction significantly ameliorates cerebral energy metabolism via boosting citrate cycle, which mainly embodies the enhancements of blood glucose concentration, glucose and lactate transportation and glucose utilization, as well as the regulations of relative enzymes activities in citrate cycle. These ameliorations ultimately resulted in numerous ATP yield after stroke, which improved neurological function and infarcted volume. Collectively, it suggests that SSS extraction has exerted advantageous effect in the treatment of cerebral ischemia. Ethics Statement All animal operations were accor...

Transcranial Direct Current Stimulation Use in Warfighting: Benefits, Risks, and Future Prospects
Conclusion The aim of this paper was to examine whether military tDCS use can be efficacious and ethical in military settings. Our assessment is that tDCS offers a number of cognitive, motor, and perceptual enhancement opportunities which could provide value in military situations like training and operations. There is potential scope for use in a number of key areas that directly affect practical battlefield advantage and survivability, such as deceptive capabilities, risk-taking, threat detection, perception, and physiological improvement. Additionally, tDCS has the potential to improve command and control decision maki...

Successful endovascular recanalization of a partially occluded basilar artery fenestration.
Authors: Meinel TR, Pult F, Gralla J, Arnold M, Bassetti C, Jung S Abstract A 76-year-old man with a history of arterial hypertension, obstructive sleep apnea, dyslipidemia, family history of cardiovascular events, prestroke and overweight presented 90 minutes after acute onset of right-sided sensorimotor hemiparesis, hemiataxia and dysarthria (National Institutes of Health Stroke Scale (NIHSS) 9/42). Magnetic resonance imaging (MRI) revealed a pontine ischemia and MR angiography showed a thrombus in the middle to distal portion of the basilar artery. Owing to the location, an occlusion of one lumen of a fenestrate...
