It has been well recognized that arterial stiffness and wave reflection measured by the aortic pulse wave velocity and Augmentation Index (AIx) are the strong predictors of future Cardiovascular events and all-cause mortality [1,2]. However, these measures require technical expertise and knowledge. In this context, the Second Derivative waveform of fingertip Photoplethysmography (SDPTG) can be measured easily from a fingertip placed on the photoplethysmography (PTG) sensor and has the potential for selfmonitoring of vascular health during daily living [3]. Previously, several studies have demonstrated clinical and pathophysiological importance of SDPTG indices such as the SDPTG Aging Index (SDPTGAI) [4–6]. Since SDPTGAI is strongly correlated with age, it can be rescaled to years of age which is easily comprehended by general populations [3]. For these reasons, SDPTG indices including the vascular aging index have recently been implemented for ambulatory monitoring devices, but its usability and reliability are not well documented. Mental stress is an external stimulus that can affect physiological parameters such as arterial tone [5,7], blood viscosity [8], and heart rate [9]. It is reported that pulse wave velocity and AIx are increased with acute mental stress [10,11]. Moreover, skin blood flow shows transient reflex changes in response to various external stimuli (e.g., arousing or painful stimuli, emotional stress) [12]. Since photoplethysmogram optically evaluates blood volume changes in the microvascular bed of cutaneous tissue, SDPTG may be influenced by mental stressor independent of changes in vascular tone and stiffness of the relatively proximal vessels.","PeriodicalId":8466,"journal":{"name":"Artery Research","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69872192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to compare the effects of interventional and conservative therapies on lower extremity ASO, and to analyze the risk factors for prognosis. Methods: Ninety-eight eligible patients were randomly divided into experimental ( n = 50) and control groups ( n = 48). Conservative therapy was conducted for control group, and experimental group was given conservative and interventional therapies. Their baseline clinical data, hospital stay length, claudication distance, Rutherford stage, diseased arteries, Ankle-Brachial Index (ABI), clinical outcomes and adverse events were recorded. Then they were divided into poor ( n = 31) and good prognosis groups ( n = 67), and risk factors were explored by univariate and multivariate analyses. Results: The hospital stay length of experimental group was significantly shorter than that of control group ( p < 0.05). After treatment, Rutherford stage decreased, and vascular patency rate and total response rate rose in experimental group ( p < 0.05). Claudication distance and ABI significantly increased in both groups compared with those before treatment, especially in experimental group ( p < 0.05). The incidence rates of cardiovascular and cerebrovascular events, amputation and death were significantly lower in experimental group ( p < 0.05). Age, conservative therapy, smoking, hypertension, diabetes mellitus, hyperlipidemia and fibrinogen were independent risk factors for poor prognosis ( p < 0.05). Age of >70 years old and fibrinogen level of >4 g/L had greater effects on prognosis. Conclusion: Interventional therapy works well for lower extremity ASO, with high safety, easy recovery and mild complications. Poor prognosis is caused by old age, conservative therapy, smoking,","PeriodicalId":8466,"journal":{"name":"Artery Research","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44873544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effect sizes are commonly used in reference to Cohen's seminal guidelines of small (d = 0.2), medium (d = 0.5), and large (d = 0.8). Quantitative analyses of effect size distributions across various research disciplines have revealed values differing from Cohen's original recommendations. Here we examine effect size distributions in human endothelial function research, and the magnitude of small, medium, and large effects for macro and microvascular endothelial function.Methods: Effect sizes reported as standardized mean differences were extracted from meta research available for endothelial function. A frequency distribution was constructed to sort effect sizes. The 25th, 50th, and 75th percentiles were used to derive small, medium, and large effects. Group sample sizes and publication year from primary studies were also extracted to observe any potential trends, related to these factors, in effect size reporting in endothelial function research.Results: Seven hundred fifty-two effect sizes were extracted from eligible meta-analyses. We determined small (d = 0.28), medium (d = 0.69), and large (d = 1.21) effects for endothelial function that corresponded to the 25th, 50th, and 75th percentile of the data distribution.Conclusion: Our data indicate that direct application of Cohen's guidelines would underestimate the magnitude of effects in human endothelial function research. This investigation facilitates future a priori power analyses, provides a practical guiding benchmark for the contextualization of an effect when no other information is available, and further encourages the reporting of effect sizes in endothelial function research.","PeriodicalId":8466,"journal":{"name":"Artery Research","volume":"27 4","pages":"176-185"},"PeriodicalIF":0.6,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8654719/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39860494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
