Objectives: post-stroke depression (PSD), cognitive impairment, and sleep disturbances are the most common post-stroke conditions. To aid clinical practice for a highly confounded clinical problem, a clearer understanding of the associations between comorbid PSD, post-stroke cognitive impairment, and sleep disturbances is necessary. Materials and Methods: a scoping review of the literature was conducted according to the recommended guidelines using the search term [“stroke (mesh term) AND depression (in the abstract) AND cognitive (in the abstract) AND sleep (in the abstract)”]. Results: 10 studies met the criteria for inclusion. Only one study reported a co-occurrence of post-stroke emotional distress and sleep disturbances at a rate of 10.7%. Poor sleep and cognitive impairment are independent risk factors for PSD. The relationship between post-stroke poor sleep and cognitive impairment is ambiguous. None of the studies examined how PSD, cognitive impairment, and sleep disturbances interact to influence stroke outcomes. Conclusions: the dearth of studies indicates either a lack of awareness of the potential relationship between the three outcomes and the possible range of inter-related non-motor outcomes after stroke or the practical challenges in designing appropriate studies. The included studies had methodological weaknesses in their observational design and use of imprecise, subjective outcome measurements. Important knowledge gaps are identified for future research.

Background: This is a retrospective analysis of the results of treatment for varicose veins using the sandwich technique with cyanoacrylate glue and foam sclerotherapy. This novel method allows for a substantial reduction in the amount of glue needed for vein closure, and minimizes the risk of granuloma formation and allergic reaction related to the epifascial administration of cyanoacrylate. Methods: This technique was used in 60 patients, 77 intrafascial veins were managed. Vein closures were performed with Venex cyanoacrylate glue and 1–3% polidocanol foam. All procedures were performed under ultrasonographic control, through direct percutaneous punctures of target veins. Follow-ups were scheduled 1–3 weeks after the procedure. If revealed, unclosed segments of the target veins were obliterated at these follow-up visits, with glue and/or sclerotherapy. Results: There were no serious adverse events intra- or postprocedurally. The technical success rate was 100%. The primary success rate at 1–3 weeks follow-up was 84.4%. The primary assisted success rate, after additional closures, was 100%. Conclusions: We demonstrated that the treatment for varicose veins, using a sandwich technique, which combines cyanoacrylate glue and foam sclerotherapy, can be safe and efficient. Full article

Background: Cardiovascular disease is a leading cause of illness and death globally, primarily due to atherosclerosis. This disease reduces blood flow and oxygen delivery to organs, and when it affects the carotid arteries, it can lead to cognitive impairment and dementia. In a population of 104 individuals, comprising both healthy controls and individuals at elevated risk for developing cardiovascular diseases (CVD) due to identified risk factors, we used PET imaging with ¹⁸F-fluorodeoxyglucose (FDG) to assess cerebral glucose metabolism and ¹⁸F-sodium fluoride (NaF) to detect atherosclerotic calcification. Our statistical analysis revealed significant differences in metabolic activity between healthy and at-risk individuals in specific brain regions. ¹⁸F-FDG uptake in the brain varied inversely with respect to the clinical assessment of cardiovascular risk in regions such as the cuneus (β = −0.030, SE = 0.014, p = 0.035), middle occipital gyrus (β = −0.032, SE = 0.011, p = 0.005), and posterior cingulate gyrus (β = −0.032, SE = 0.015, p = 0.044). In contrast, areas including the basis pontis (β = 0.025, SE = 0.012, p = 0.038) and the pons (β = 0.034, SE = 0.013, p = 0.008) exhibited direct correlations. Notably, carotid ¹⁸F-NaF uptake had inverse associations with ¹⁸F-FDG uptake in the cerebellum (β = −0.825, SE = 0.354, p = 0.021), medulla (β = −0.888, SE = 0.405, p = 0.029), and posterior cingulate gyrus (β = −1.253, SE = 0.567, p = 0.028), while increased carotid calcification influenced metabolic activity in the fusiform gyrus (β = 1.660, SE = 0.498, p = 0.001) and globus pallidus (β = 1.505, SE = 0.571, p = 0.009). We observed that atherosclerotic plaque accumulation, especially in the carotid arteries, has potential implications for metabolic changes in brain regions governing cognition, emotion, sensory perception, and motor activities. Our findings underscore the possible early interventions that can be used to preempt or delay cognitive deterioration linked with cardiovascular ailments. Full article
