Article Abstract
Introduction: This study investigates pre-atherosclerotic changes, vascular aging and clinical cardiovascular disease (CVD) risk scores in young adults with embolic stroke of undetermined source (ESUS) compared to stroke-free controls.
Methods: The study included 105 ESUS patients and 105 age- and sex-matched stroke-free controls aged 18 to 49 years. Clinical and laboratory characteristics and arterial stiffness measurements were recorded. Vascular aging indexes were defined according to age-adapted values and definitions. Clinical scores PREVENT and SCORE2 were calculated. Associations were investigated using logistic regression adjusting for several factors associated with vascular aging.
Results: Young ESUS patients had higher rates of central obesity, smoking, heavy alcohol consumption and patent foramen ovale compared to stroke-free controls. ESUS patients had higher odds of having excessive intima-media thickness (IMT) of the right carotid artery (OR 3.02, 95 %CI:1.31-6.92). They also had significantly higher odds of having elevated estimated pulse wave velocity (ePWV>9 m/s; OR 8.48, 95 %CI:2.16-33.4), high pulse pressure (PP ≥ 60 mmHg; OR 3.13, 95 %CI:1.28-7.68), a 10-year CVD risk above 5 % based on the PREVENT score (OR 8.53, 95 %CI:1.59-45.7), and a 10-year CVD risk above 2.5 % based on SCORE2 (OR 26.5, 95 %CI:3.6-193.6) estimated at the time of their stroke.
Conclusions: Despite a low burden of established CVD, young ESUS patients harbored pathology in the vascular aging measures including IMT, ePWV, and PP. Clinical risk scores such as PREVENT and SCORE2 may effectively identify young adults at high risk of developing ESUS.

Vasoconstrictor responsiveness in resting and contracting skeletal muscle following an acute bout of exercise: Impact of aging.
J Appl Physiol (1985)

Long-term exercise training can attenuate sympathetic vasoconstriction in both resting and contracting skeletal muscle; however, the impact of an acute bout of exercise on vasoconstrictor responsiveness and the influence of aging is unknown. Therefore, we tested the hypothesis that an acute bout of exercise will blunt sympathetic-mediated vasoconstriction in resting and contracting skeletal muscle of young and older adults. Twenty-one adults (10 Young: 23±5 yr and 11 Older: 65±8 yr) performed a rest and a rhythmic handgrip exercise trial before and after either 30 minutes of cycling exercise (60-65% HRmax) or a time control period (seated rest).

Acute ischemic stroke (AIS) remains a leading cause of mortality and long-term disability globally, with survivors at high risk of recurrent stroke, cardiovascular events, and post-stroke dementia. Statins, while widely used for their lipid-lowering effects, also possess pleiotropic properties, including anti-inflammatory, endothelial-stabilizing, and neuroprotective actions, which may offer added benefit in AIS management. This article synthesizes emerging evidence on statins' dual mechanisms of action and evaluates their role in reducing recurrence, improving survival, and mitigating cognitive decline.

Purpose: To investigate the role of personal risk factors in the occurrence of the vascular, neurological and fibroproliferative disorders of the hand-arm vibration syndrome (HAVS) in workers groups exposed to hand-transmitted vibration (HTV).
Methods: HAVS prevalence and incidence data were pooled across a series of cross-sectional studies (total sample: 1272 HTV workers, 579 controls) and prospective cohort studies (total sample: 377 HTV workers, 138 controls) conducted in Central and North-Eastern Italy. The pooled studies included detailed individual-level information about HTV exposure, personal risk factors, medical comorbidities and HAVS disorders.
Burn Injury Triggers Distinct Transcriptomic Profiles in Adipose Tissue of Adult and Aged Mice.
FASEB J

Department of Surgery, McMaster University, Hamilton, Ontario, Canada.
Severe burns are a major global health concern, and are associated with long-term physical and psychological impairments, multi-organ dysfunction, and substantial morbidity and mortality. While burn injuries in adults trigger systemic immuno-metabolic alterations-characterized by white adipose tissue browning, elevated resting energy expenditure, widespread catabolism, and inflammation-these adaptive responses are considerably impaired in older adults, with molecular mechanisms behind these differences remaining largely unclear. As a key regulator of systemic metabolism, investigating the pathological role of adipose tissue (AT) postburn may reveal novel targets that could potentially improve patient outcomes.

Background: The global burden of dementia is increasing, particularly in low- and middle-income countries. Dementia with Lewy bodies (DLB) is the second most common neurodegenerative dementia but remains underreported and frequently misdiagnosed. Its prevalence in Latin America is largely unknown.
