This study investigated the potential association between uranium exposure and mortality from cerebrovascular diseases, with a focus on the mediating effects of lipid indicators. Employing recommended sampling weights to account for National Health and Nutrition Examination Survey' complex survey design, this analysis drew from data collected between 2005 and 2016. The study examined the impact of uranium on mortality from cerebrovascular diseases using various statistical approaches, including Cox regression to assess linear relationships within metal mixtures. ⋯ The study encompassed 4312 participants and established a significant direct link between uranium levels and mortality from cerebrovascular diseases (hazard ratio (95%CI) = 20.4243 (20.1347-20.7181), P = .0266). It also identified LAP as a mediating factor in the relationship, accounting for a mediated proportion of 1.35%. The findings highlight a pivotal connection between uranium exposure and increased mortality due to cerebrovascular diseases, with LAP playing a significant intermediary role.

ReviewVascular cognitive impairment: Advances in clinical research and management.
Vascular cognitive impairment (VCI) encompasses a wide spectrum of cognitive disorders, ranging from mild cognitive impairment to vascular dementia. Its diagnosis relies on thorough clinical evaluations and neuroimaging. VCI predominately arises from vascular risk factors (VRFs) and cerebrovascular disease, either independently or in conjunction with neurodegeneration. ⋯ Identifying appropriate pharmacological approaches is also of paramount importance. In this review, we synthesize recent advancements in the field of VCI, including its definition, determinants of vascular risk, pathophysiology, neuroimaging and fluid-correlated biomarkers, predictive methodologies, and current intervention strategies. Increasingly evident is the notion that more rigorous research for VCI, which arises from a complex interplay of physiological events, is still needed to pave the way for better clinical outcomes and enhanced quality of life for affected individuals.

High cardiorespiratory fitness (CRF) has been associated with a lower risk of depression, anxiety, and cerebrovascular disease. The aim was to explore CRF changes over-time associated with these outcomes. ⋯ The findings indicate that there is a longitudinal association between negative change in estCRF and increased risk of depression, anxiety, and cerebrovascular disease later in life. Decreasing levels of estCRF could be a helpful indicator when identifying these disorders at a population level.

The incidence of pediatric hospitalizations has significantly increased since the spread of the omicron variant of COVID-19. Changes of characteristics in respiratory and neurological symptoms have been reported. We performed a retrospective, cross-sectional study to characterize the MRI change in children with an emphasis on the change of cerebral vasculatures. ⋯ A high proportion of vascular abnormalities was observed in pediatric patients with neurological involvements, suggesting that vascular involvement is an important mechanism of neurological manifestations in omicron variant infection.

A rare presentation of unilateral carotid rete mirabile (RM) in a 70-year-old male manifesting as limb-shaking transient ischemic attacks, a disorder typically associated with carotid artery stenosis. The patient experienced recurrent left-sided limb shaking and numbness, with angiography revealing an anomalous microarterial collateral network replacing the right internal carotid artery's cavernous segment, indicative of RM. ⋯ The patient's management involved antiplatelet therapy and lifestyle changes, following which he reported no further cerebrovascular events. This case underscores the importance of considering RM in differential diagnoses of limb-shaking transient ischemic attack and suggests conservative management as a favorable approach.
