It serves as a crucial building block for proteins. At the same time, as a bioactive molecule, it regulates gene expression for cytoprotection, protein configuration and activity, and other critical biological processes, including glutathione synthesis. The intriguing, beneficial effects of glycine in medical applications have piqued the research community’s interest in recent decades. This work delves into the compelling discoveries about the pivotal role of glycine in cardiovascular health and its intricate mechanisms of action for alleviating several medical conditions. Glycine’s broad spectrum of impact spans numerous diseases, encompassing not only acute myocardial infarction, aortic dissection, and cardiac hypertrophy, but also transplant rejections of aortic allografts, insulin resistance, and endothelial dysfunction, thereby providing a comprehensive understanding of its medical applications.","PeriodicalId":74009,"journal":{"name":"Journal of vascular diseases","volume":"75 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141377448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Almodovar","doi":"10.3390/jvd3020015","DOIUrl":"https://doi.org/10.3390/jvd3020015","url":null,"abstract":"People living with HIV (PLWH) face a growing burden of chronic diseases, owing to the combinations of aging, environmental triggers, lifestyle choices, and virus-induced chronic inflammation. The rising incidence of pulmonary vascular diseases represents a major concern for PLWH. The study of HIV-associated pulmonary vascular complications ideally requires a strong understanding of pulmonary vascular cell biology and HIV pathogenesis at the molecular level for effective applications in infectious diseases and vascular medicine. Active HIV infection and/or HIV proteins disturb the delicate balance between vascular tone and constriction, which is pivotal for maintaining pulmonary vascular health. One of the defining features of HIV is its high genetic diversity owing to several factors including its high mutation rate, recombination between viral strains, immune selective pressures, or even geographical factors. The intrinsic HIV genetic diversity has several important implications for pathogenic outcomes of infection and the overall battle to combat HIV. Challenges in the field present themselves from two sides of the same coin: those imposed by the virus itself and those stemming from the host. The field may be advanced by further developing in vivo and in vitro models that are well described for both pulmonary vascular diseases and HIV for mechanistic studies. In essence, the study of HIV-associated pulmonary vascular complications requires a multidisciplinary approach, drawing upon insights from both infectious diseases and vascular medicine. In this review article, we discuss the fundamentals of HIV virology and their impact on pulmonary disease, aiming to enhance the understanding of either area or both simultaneously. Bridging the gap between preclinical research findings and clinical practice is essential for improving patient care. Addressing these knowledge gaps requires interdisciplinary collaborations, innovative research approaches, and dedicated efforts to prioritize HIV-related pulmonary complications on the global research agenda.","PeriodicalId":74009,"journal":{"name":"Journal of vascular diseases","volume":"119 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141007051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Noninvasive arterial stiffness indices, the arterial velocity–pulse index (AVI) and the arterial pressure–volume index (API) have been associated with CV risks, conventional arterial stiffness indices, and the severity of coronary atherosclerosis. However, few studies have examined the relationship between these indices and the occurrence of CV events. We measured the AVI and API in 113 consecutive patients admitted to Yokohama City University Hospital for cardiac catheterization between June 2015 and March 2016. Patients were followed until September 2022, and the occurrence of CV events was assessed. The mean age was 71.2 ± 10.7 years, and 83 patients (73.5%) were male. In total, 80 patients (70.8%) had hypertension, 87 (77.0%) had dyslipidemia, and 91 (80.5%) had a history of ischemic heart disease (IHD). The mean follow-up duration was 1752 ± 819 days. Patients who received elective percutaneous coronary intervention (PCI) based on the results of coronary angiography (CAG) at the time of enrollment had significantly higher API than those who did not (38.5 ± 12.6, n = 17 vs. 31.3 ± 7.4, n = 96, p = 0.001). The API was independently associated with the risk of elective PCI in multiple logistic regression analysis. In conclusion, the API could be a useful indicator for estimating the need for coronary interventional treatment in patients with a high CV risk.","PeriodicalId":74009,"journal":{"name":"Journal of vascular diseases","volume":"249 1‐2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141012835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":74009,"journal":{"name":"Journal of vascular diseases","volume":"40 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140771504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chronic sGC activation enhanced vascular function in the congestive heart failure animal model. Therefore, sGC activation can lead to vasodilation and improvement in endothelial function. Objective: To investigate whether the selective sGC activator can revert the endothelial dysfunction and investigate the mechanism of action. Methods: Wistar rats were split into two groups: normotensive (2K) and hypertensive rats (2K-1C). Intact aortic rings were placed in a myograph and incubated with 0.1 µM ataciguat for 30 min. Cumulative concentration-effect curves were generated for acetylcholine (Ach) to assess endothelial function. The pD2 and maximum relaxant effect (Emax) were measured to Ach. In endothelial cell culture, superoxide anion (O2•−) was detected by using fluorescent probes, including DHE and lucigenin. Results: Ataciguat improved the relaxation induced by acetylcholine in 2K-1C (pD2: 6.99 ± 0.08, n = 6) compared to the control (pD2: 6.43 ± 0.07, n = 6, p < 0.05). The aortic rings were also improved from 2K (pD2: 7.04 ± 0.13, n = 6) compared to the control (pD2: 6.59 ± 0.07, n = 6, p < 0.05). Moreover, Emax was improved by ataciguat treatment in the 2K-1C aorta (Emax: 81.0 ± 1.0; n = 6), and 2K aorta (Emax: 92.98 ± 1.83; n = 6), compared to the control (Emax 2K-1C: 52.14 ± 2.16, n = 6; and Emax 2K: 76.07 ± 4.35, n = 6, p < 0.05). In endothelial cell culture, treatment with ataciguat (0.1, 1, and 10 µM) resulted in a reduction of the superoxide anion formation induced by angiotensin II. Conclusions: Our findings indicated that ataciguat effectively enhanced endothelial function through the inactivation of superoxide anions.","PeriodicalId":74009,"journal":{"name":"Journal of vascular diseases","volume":"96 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140079629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We explore the integration of functional assessment approaches into existing procedures, highlighting the potential of technology-assisted rehabilitation, including wearable sensors and digital biomarkers, to enhance the effectiveness of managing and preventing VOCs. Rehabilomics, as a comprehensive framework, merges rehabilitation-related data with biomarkers, providing a basis for personalized therapeutic interventions. Despite the promising advantages of these approaches, persistent obstacles such as the limited availability of rehabilitation programs, especially in resource-limited settings, pose challenges. This paper underscores the importance of a collaborative strategy to effectively address the unique obstacles faced by patients with SCD. This collaborative approach involves improving accessibility to rehabilitation services, incorporating technology-supported therapy, and fostering focused research endeavors. The primary objective of this comprehensive approach is to enhance the overall care of SCD patients, with a specific focus on preventing VOCs, as well as providing tailored (neuro)rehabilitation services in resource-limited settings.

Vasoactive drugs are considered an important therapeutic tool in managing phlebolymphologic disease. The current study was performed to evaluate the results of a high-dose diosmin-based combination (Venoplant 2g) in symptomatic patients with chronic venous disease (CVD), treated with endovascular venous surgery, regarding the efficacy of this treatment and the clinical signs and patients’ compliance. Methods: We identified, between April 2022 and March 2023, 50 patients with symptomatic CVD who underwent endovenous ablation and additionally were administered high-dose micronized diosmin. Parameters analyzed in the pre- and post-operative period were the venous clinical severity score (VCSS), the calf circumference, and a VEINES-QOL/Sym questionnaire. Treatment efficacy was assessed in post-operative follow-ups at 1 month and 2 months. Results: Quality-of-life analysis showed a significant improvement between t1 and t2 in both tests administered (VEINES-QOL/Sym: 55.2 ± 2.9, 39.2 ± 12.3, p: 0.001) (VCSS: 6.6 ± 1, 5.1 ± 0.7, p: 0.001).
