Xu Y, Pouncey AL, Zhou Z, Woodward M, Harris K. Smoking as a risk factor for lower extremity peripheral artery disease in women compared to men: A systematic review and meta-analysis. PLoS One 2024; 19:e0300963. [PMID: 38656947 PMCID: PMC11042699 DOI: 10.1371/journal.pone.0300963] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Accepted: 03/07/2024] [Indexed: 04/26/2024] Open
Abstract
BACKGROUND To investigate whether the relationship between smoking and peripheral artery disease (PAD) differs by sex (PROSPERO CRD42022352318). METHODS PubMed, EMBASE, and CINAHL were searched (3 March 2024) for studies reporting associations between smoking and PAD in both sexes, at least adjusted for age. Data were pooled using random effects. Between-study heterogeneity was examined using I2 statistic and Cochran's Q test. Newcastle-Ottowa Scale was adopted for quality assessment. RESULTS Four cohort studies (n = 2,117,860, 54.4% women) and thirteen cross-sectional studies (n = 230,436, 59.9% women) were included. In cohort studies, former and current smokers had higher risk of PAD than never smokers. Compared to those who never or previously smoked, women current smokers (relative risk (RR) 5.30 (95% confidence interval 3.17, 8.87)) had higher excess risk of PAD than men (RR 3.30 (2.46, 4.42)), women-to-men ratio of RR 1.45 (1.30, 1.62)(I2 = 0%, p = 0.328). In cross-sectional studies, risk of PAD was higher among former and current compared to never smokers, more so in men, women-to-men ratios of odds ratio: 0.64 (0.46, 0.90)(I2 = 30%, p = 0.192), 0.63 (0.50, 0.79)(I2 = 0%, p = 0.594), respectively. For both sexes, risk of PAD was higher among current smokers compared to those who were not currently smoking. Cohort studies and five cross-sectional studies were of good quality, scoring 6 to 8 of a possible maximum 9 points. Eight cross-sectional studies scored 2 to 5. DISCUSSIONS Further research is required to elucidate sex differences in the relationships between smoking and PAD, as the current evidence is limited and mixed. Tobacco-control programs should consider both sexes.

Froldi G. View on Metformin: Antidiabetic and Pleiotropic Effects, Pharmacokinetics, Side Effects, and Sex-Related Differences. Pharmaceuticals (Basel) 2024; 17:478. [PMID: 38675438 PMCID: PMC11054066 DOI: 10.3390/ph17040478] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 03/29/2024] [Accepted: 04/03/2024] [Indexed: 04/28/2024] Open
Abstract
Metformin is a synthetic biguanide used as an antidiabetic drug in type 2 diabetes mellitus, achieved by studying the bioactive metabolites of Galega officinalis L. It is also used off-label for various other diseases, such as subclinical diabetes, obesity, polycystic ovary syndrome, etc. In addition, metformin is proposed as an add-on therapy for several conditions, including autoimmune diseases, neurodegenerative diseases, and cancer. Although metformin has been used for many decades, it is still the subject of many pharmacodynamic and pharmacokinetic studies in light of its extensive use. Metformin acts at the mitochondrial level by inhibiting the respiratory chain, thus increasing the AMP/ATP ratio and, subsequently, activating the AMP-activated protein kinase. However, several other mechanisms have been proposed, including binding to presenilin enhancer 2, increasing GLP1 release, and modification of microRNA expression. Regarding its pharmacokinetics, after oral administration, metformin is absorbed, distributed, and eliminated, mainly through the renal route, using transporters for cationic solutes, since it exists as an ionic molecule at physiological pH. In this review, particular consideration has been paid to literature data from the last 10 years, deepening the study of clinical trials inherent to new uses of metformin, the differences in effectiveness and safety observed between the sexes, and the unwanted side effects. For this last objective, metformin safety was also evaluated using both VigiBase and EudraVigilance, respectively, the WHO and European databases of the reported adverse drug reactions, to assess the extent of metformin side effects in real-life use.

Abstract
Clinical and basic studies have documented that both hyperglycemia and insulin-resistance/hyperinsulinemia not only constitute metabolic disorders contributing to cardiometabolic syndrome, but also predispose to diabetic vasculopathy, which refers to diabetes-mellitus-induced microvascular and macrovascular complications, including retinopathy, neuropathy, atherosclerosis, coronary artery disease, hypertension, and peripheral artery disease. The underlying molecular and cellular mechanisms include inappropriate activation of the renin angiotensin-aldosterone system, mitochondrial dysfunction, excessive oxidative stress, inflammation, dyslipidemia, and thrombosis. These abnormalities collectively promote metabolic disorders and further promote diabetic vasculopathy. Recent evidence has revealed that endothelial progenitor cell dysfunction, gut dysbiosis, and the abnormal release of extracellular vesicles and their carried microRNAs also contribute to the development and progression of diabetic vasculopathy. Therefore, clinical control and treatment of diabetes mellitus, as well as the development of novel therapeutic strategies are crucial in preventing cardiometabolic syndrome and related diabetic vasculopathy. The present review focuses on the relationship between insulin resistance and diabetes mellitus in diabetic vasculopathy and related cardiovascular disease, highlighting epidemiology and clinical characteristics, pathophysiology, and molecular mechanisms, as well as management strategies.

Abstract
Peripheral artery disease (PAD) is caused by blocked arteries due to atherosclerosis and/or thrombosis which reduce blood flow to the lower limbs. It results in major morbidity, including ischemic limb, claudication, and amputation, with patients also suffering a heightened risk of heart attack, stroke, and death. Recent studies suggest women have a higher prevalence of PAD than men, and with worse outcomes after intervention. In addition to a potential unconscious bias faced by women with PAD in the health system, with underdiagnosis, and lower rates of guideline-based therapy, fundamental biological differences between men and women may be important. In this review, we highlight sexual dimorphisms in endothelial cell functions and how they may impact PAD pathophysiology in women. Understanding sex-specific mechanisms in PAD is essential for the development of new therapies and personalized care for patients with PAD.

Sex differences in risk factors for incident peripheral artery disease hospitalisation or death: Cohort study of UK Biobank participants. PLoS One 2023; 18:e0292083. [PMID: 37851596 PMCID: PMC10584119 DOI: 10.1371/journal.pone.0292083] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Accepted: 09/12/2023] [Indexed: 10/20/2023] Open
Abstract
BACKGROUND Women with peripheral artery disease (PAD) often have atypical symptoms, late hospital presentations, and worse prognosis. Risk factor identification and management are important. We assessed sex differences in associations of risk factors with PAD. METHODS 500,207 UK Biobank participants (54.5% women, mean age 56.5 years) without prior hospitalisation of PAD at baseline were included. Examined risk factors included blood pressure, smoking, diabetes, lipids, adiposity, history of stroke or myocardial infarction (MI), socioeconomic status, kidney function, C-reactive protein, and alcohol consumption. Poisson and Cox regressions were used to estimate sex-specific incidence of PAD hospitalisation or death, hazard ratios (HRs), and women-to-men ratios of HRs (RHR) with confidence intervals (CIs). RESULTS Over a median of 12.6 years, 2658 women and 5002 men had a documented PAD. Age-adjusted incidence rates were higher in men. Most risk factors were associated with a higher risk of PAD in both sexes. Compared with men, women who were smokers or had a history of stroke or MI had a greater excess risk of PAD (relative to those who never smoked or had no history of stroke or MI): RHR 1.18 (95%CI 1.04, 1.34), 1.26 (1.02, 1.55), and 1.50 (1.25, 1.81), respectively. Higher high-density lipoprotein cholesterol (HDL-C) was more strongly associated with a lower risk of PAD in women than men, RHR 0.81 (0.68, 0.96). Compared to HDL-C at 40 to 60 mg/dL, the lowest level of HDL-C (≤40 mg/dL) was related to greater excess risk in women, RHR 1.20 (1.02, 1.41), whereas the highest level of HDL-C (>80 mg/dL) was associated with lower risk of PAD in women, but higher risk in men, RHR 0.50 (0.38, 0.65). CONCLUSIONS While the incidence of PAD was higher in men, smoking and a history of stroke or MI were more strongly associated with a higher risk of PAD in women than men. HDL-C was more strongly associated with a lower risk of PAD in women than men.

Diagnostics (Basel) 2023; 13:3145. [PMID: 37835888 PMCID: PMC10572938 DOI: 10.3390/diagnostics13193145] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Revised: 09/30/2023] [Accepted: 10/02/2023] [Indexed: 10/15/2023] Open
Abstract
Background and Objectives: Peripheral artery disease (PAD) affects both genders, but the knowledge of clinical and therapeutic aspects particular to each gender has a prognostic value, modulating the risk of amputation and helping to reduce the risk of death or the occurrence of an acute vascular event secondary to optimal management. Materials and Methods: We conducted a retrospective, descriptive study that included 652 patients with PAD who were evaluated at "St. Spiridon" Hospital's Cardiology Department and divided into two groups according to gender: women (100 cases) and men (552 cases). We evaluated demographics, anthropometric data, as well as clinical and paraclinical parameters in the two groups. Results: Men had a lower mean age (p < 0.001), higher mean BMI (p = 0.049) and were more frequent smokers. (p = 0.008). Hypercholesterolemia (p = 0.026), obesity (p = 0.009), concomitant cerebrovascular (p = 0.005) and chronic kidney disease (p = 0.046) were more common in women, while coronary artery disease (p = 0.033) was more common in men. The number of angiographic stenotic lesions (p = 0.037) is a statistically significant parameter in our study, with both genders predominantly associated with stenotic lesions. In addition, directly proportional relationships were found between smoking, uric acid, inflammatory markers, and the number of stenotic lesions and thromboses or the ankle-brachial index (ABI). In the subgroup of men, the number of stenotic and thrombosed lesions positively correlated with the ABI value (p < 0.001). The presence of more than three cardiovascular risk factors (p = 0.001) and serum triglyceride levels (p = 0.019) significantly correlated with the number of angiographically detected lesions. We applied several risk scores (PREVENT III, Finnvasc Score, or GermanVasc risk score) in our study group for prognostic purposes, without showing statistically significant differences between genders. Men, rest pain, gangrene, smoking status, the presence of more than three cardiovascular risk factors, or a serum HDL-cholesterol level below 40 mg/dL (p < 0.001 for all parameters) are independent predictors associated with amputation in our study group. Conclusions: In our study, we demonstrated that several clinical-paraclinical particularities guide the diagnosis, providing the clinician with prognostic and therapeutic tools to choose the optimal management with maximum benefits.

Clinical Features of Diabetes Mellitus on Rheumatoid Arthritis: Data from the Cardiovascular Obesity and Rheumatic DISease (CORDIS) Study Group. J Clin Med 2023; 12:jcm12062148. [PMID: 36983150 PMCID: PMC10058987 DOI: 10.3390/jcm12062148] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 03/06/2023] [Accepted: 03/08/2023] [Indexed: 03/12/2023] Open
Abstract
Rheumatoid arthritis (RA) and diabetes mellitus (DM) are linked by underlying inflammation influencing their development and progression. Nevertheless, the profile of diabetic RA patients and the impact of DM on RA need to be elucidated. This cross-sectional study includes 1523 patients with RA and no episodes of cardiovascular events, followed up in 10 Italian University Rheumatologic Centers between 1 January and 31 December 2019 belonging to the “Cardiovascular Obesity and Rheumatic DISease (CORDIS)” Study Group of the Italian Society of Rheumatology. The demographic and clinical features of DM RA patients were compared to non-diabetic ones evaluating factors associated with increased risk of DM. Overall, 9.3% of the RA patients had DM, and DM type 2 was more common (90.2%). DM patients were significantly older (p < 0.001), more frequently male (p = 0.017), with a significantly higher BMI and mean weight (p < 0.001) compared to non-diabetic patients. DM patients were less likely to be on glucocorticoids (p < 0.001), with a trend towards a more frequent use of b/ts DMARDs (p = 0.08), and demonstrated higher HAQ (p = 0.001). In around 42% of patients (n = 114), DM diagnosis preceded that of RA. Treatment lines were identical in diabetic and non-diabetic RA patients. DM is a comorbidity that may influence RA management and outcome. The association between DM and RA supports the theory of systemic inflammation as a condition underlying the development of both diseases. DM may not have a substantial impact on bDMARDs resistance, although further investigation is required to clarify the implications of biological therapy resistance in RA patients.

Predictors for the Development of Major Adverse Limb Events after Percutaneous Revascularization—Gender-Related Characteristics. Medicina (B Aires) 2023; 59:medicina59030480. [PMID: 36984481 PMCID: PMC10053190 DOI: 10.3390/medicina59030480] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 02/20/2023] [Accepted: 02/27/2023] [Indexed: 03/05/2023] Open
Abstract
Background and Objectives: Revascularization has been proven to be superior to medication for symptom improvement in patients with peripheral arterial disease (PAD). There are well known gender differences in therapeutic strategies for PAD. The influence of gender on post-angioplasty prognosis is not fully understood though. The present study aims to identify potential peculiarities between men and women undergoing peripheral angioplasty, as well as factors responsible for those differences. Material and methods: 104 consecutive subjects (50 women and 54 men) who underwent percutaneous angioplasty (PTA) between January and October 2019 for symptomatic PAD were included. Demographics, PAD history, cardiovascular risk factors, comorbidities, the associated coronary or cerebrovascular diseases, biological parameters, drug-treatment and PTA type and technique were taken into account. The follow-up period was 2 years, during which major adverse limb events (MALE) were documented. Results: The mean age was 67 ± 10 years. Women were 4 years older than the men (69 ± 10 years vs. 65 ± 9.2 years—p = 0.04). Smoking was more prevalent in men (p = 0.0004), while other cardiovascular risk factors did not differ significantly. The mean follow-up of the two groups was 21 ± 2.4 months. Women had infra-inguinal involvement more frequently (78%), while men exhibited mixed disease, with supra + infra-inguinal (37%) or solely supra-inguinal (20.3%) involvement (p = 0.0012). Rates of MALE were similar in the two groups (p = 0.914). Gender did not influence the incidence of PAD-related adverse events. The only parameter that proved to have a significant influence on the occurrence of MALE was the ankle–brachial index (ABI). A value below 0.5 was found to be an independent predictor for MALE (p = 0.001). Conclusions: There was no significant difference in the incidence rates of MALE between the two genders over a 2-year follow-up period post-PTA. Regardless of sex, an ankle–brachial index value below 0.5 was the sole independent predictor for limb-related adverse events.

J Vasc Surg Venous Lymphat Disord 2022; 10:1229-1237.e2. [PMID: 35933108 DOI: 10.1016/j.jvsv.2022.05.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 04/25/2022] [Accepted: 05/10/2022] [Indexed: 12/24/2022]
Abstract
OBJECTIVE To evaluate the association between gender and long-term clinician-reported and patient-reported outcomes after endovenous ablation procedures. METHODS This retrospective cohort study of prospectively collected data from the Vascular Quality Initiative's Varicose Vein Registry included patients undergoing endovenous ablation procedures on truncal veins with or without treatment of perforating veins between 2015 and 2019. A univariate analysis included comparisons of preprocedural, postprocedural, and periprocedural change in Venous Clinical Severity Score (VCSS) and total symptom score by gender. Rates of complications including deep vein thrombosis, endovenous heat-induced thrombosis, leg pigmentation, blistering, paresthesia, incisional infection, and any postprocedural complications were reported by gender. Multivariable analysis leveraged linear regression to examine how gender affected the relationships between patient characteristics, complication rates, and periprocedural change in VCSS score and total symptom score. RESULTS Of 9743 patients who met the inclusion criteria, 3090 (31.7%) were men and 6653 (68.2%) were women. The perioperative change in VCSS score was greater for men than women (average -4.46 for men vs -4.13 for women; P < .0001). Perioperative change in total symptom score was greater for women than for men (average -10.64 for women vs -9.64 for men; P < .0001). Women had lower incidence of any leg complication (6.1% vs 8.6%; P = .001) endovenous heat-induced thrombosis (1.1% vs 2.2%; P = .002), and infection (0.4% vs 0.7%; P = .001). In multivariable analysis, among patients with a body mass index of more than 40, presence of deep reflux, and preoperative Clinical, Etiologic, Anatomic, and Physiologic classification of 2, women had a greater periprocedural change in VCSS score than men. CONCLUSIONS Women benefited from endovenous ablation similarly as men, with a lower incidence of postprocedural complications. Gender may be useful for patient selection and counseling for endovenous ablation, with particular usefulness among patients with a high body mass index, presence of deep reflux, and preoperative Clinical, Etiologic, Anatomic, and Physiologic classification of 2.

Abstract
This study investigated the distribution of risk factors, lesion characteristics and endovascular revascularization (EVR) strategies in patients with peripheral arterial disease (PAD) with vs without diabetes mellitus (DM). Data were collected within the RECcording COurses of vasculaR Diseases (RECCORD) registry. Demographic data, lesion localization (iliac vs femoropopliteal vs below-the-knee (BTK)) and lesion complexity score (LCS) based on number of affected segments, and lesion length (< 10 vs 10-20 vs > 20 cm), EVR strategies and peri-procedural complications were analysed in 786 patients with and 1337 without diabetes mellitus. Patients with diabetes mellitus were older (71.6 ± 9.6 vs 69.4 ± 10.5 years, P < .001) and had higher LCS and more often BTK lesions (P < .05 for all). Lesions were treated less frequently with stents (48.7 vs 59.6%, P < .001) in patients with diabetes mellitus, whereas a non-significant trend was noticed for higher DCB treatment rates (48.3 vs 44.4%, P = .07). Post-interventional ankle-brachial index (ABI) increase was similar (from .77 ± .28 to .92 ± .25 with diabetes mellitus and from .74 ± .21 to .90 ± .20 without diabetes mellitus, P < .001 for both). Peri-/post-procedural complications were low in both groups (4.6%). Patients with diabetes mellitus, who undergo endovascular revascularization are older, have more comorbidities and higher target lesion complexity. However, treatment success rates are similar and complication rates are low.

Risk of Peripheral Arterial Occlusive Disease with Periodontitis and Dental Scaling: A Nationwide Population-Based Cohort Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph191610057. [PMID: 36011700 PMCID: PMC9408091 DOI: 10.3390/ijerph191610057] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Revised: 08/11/2022] [Accepted: 08/12/2022] [Indexed: 06/01/2023]
Abstract
Periodontitis (PD) is a common oral disease associated with various other diseases, particularly those affecting the cardiovascular system. This study explored whether peripheral artery occlusive disease (PAOD) is associated with PD and dental scaling. This study was a retrospective cohort study design from 2000 to 2018. The study population was newly diagnosed with periodontitis. The comparison group was defined as never diagnosed with periodontitis. The outcome variable was defined with the diagnosis of peripheral arterial occlusive disease (PAOD). The propensity score matching was performed by age, sex, comorbidities, and dental scaling between the two groups. Kaplan-Meier analysis was used to calculate the cumulative incidence of PAOD among the two groups. To perform the independent risk of the PAOD group, the multivariate Cox proportional hazard model was used to estimate the hazard ratios. First, 792,681 patients with PD and 458,521 patients with no history of PD were selected from Taiwan's Longitudinal Health Insurance Database, which comprises the data of two million beneficiaries. After propensity score matching between the PD and non-PD groups for age, sex, comorbidities, and dental scaling, 357,106 patients in each group were analyzed for PAOD risk. The incidence density, relative risk, and cumulative incidence of PAOD were higher in the PD group than in the non-PD group. After adjusting for all variables, the risk of PAOD for the PD group was greater than for the non-PD group (adjusted hazard ratio = 1.03; 95% CI, 1.01-1.06). Undergoing at least one dental scaling procedure reduced the risk of PAOD. Age over 65 years was also a risk factor. In conclusion, patients with PD have an increased risk of PAOD. In addition, our results can lead to increased attention to oral hygiene, as dental scaling has a trend towards a lower risk of PAOD.

Abstract
Peripheral artery disease is a prevalent illness affecting more than 200 million people worldwide. A commonly used technique to manage the condition has been open endarterectomy. However, in recent times, a shift towards minimally invasive techniques has resulted in endovascular intervention as a popular alternative. This review aims to assess the safety and efficacy of endovascular intervention when compared with endarterectomy. A systematic review of the articles published in PubMed, Ovid, Embase, and Scopus within the last 10 years was conducted. The PRISMA guidelines were adhered to, and the Newcastle-Ottawa and NICE quality assessment scales were used. A meta-analysis of proportions was performed using the RStudio software (RStudio Team (2021). RStudio: Integrated Development Environment for R, PBC, Boston, MA, USA). Twenty-six studies were included, with a total of 7126 patients (endovascular, 2496; endarterectomy, 4630). Technical success was greater for endarterectomy than endovascular intervention with an odds ratio of 0.38; 95% CI [0.27–0.54]. In terms of safety as well endovascular intervention was better than endarterectomy with an odds ratio of 0.22; 95% CI [0.15 to 0.31] for wound infection. Endovascular intervention is a safe and effective procedure; however, it cannot be considered superior to endarterectomy.

Abstract
Peripheral artery disease (PAD) is a prevalent condition that confers substantial morbidity and mortality and remains underdiagnosed as well as undertreated in the overall population. Although PAD prevalence is similar or higher in women compared with men, associations of traditional and nontraditional risk factors with PAD and clinical manifestations of PAD differ by sex and may contribute to delayed or lack of diagnosis in women. Such sex-based differences in the manifestation of PAD may arise from sexual dimorphism in the vascular substrate in health as well as sex variation in the responses to vascular stressors. Despite the availability of proven therapies for improving symptoms and reducing risk of ischemic cardiovascular and limb events among patients with diagnosed PAD, important sex differences in treatment and outcomes have been observed. We provide an overview of current knowledge regarding sex differences in the epidemiology, pathophysiology, clinical presentation, and management of PAD.

Abstract
Atherosclerotic peripheral artery disease (PAD) is associated with functional limitations and an increased risk of poor cardiovascular outcomes. Although men are traditionally viewed at higher risk of PAD than women, the true prevalence and incidence is inconsistent among available reports. Some of this variability is due to differences in PAD-related symptoms among women as well as sex-based differences in diagnostic tests, such as the ankle-brachial index, and it is critical for future epidemiologic studies to account for these differences. Generally, women with PAD experience greater functional impairment and decline then men and are less likely to receive guideline-directed medical therapy. In some settings, women are also more likely to present at later stages of disease and more often undergo lower limb amputation than men. Animal data exploring the biological underpinnings of these sex differences are limited, but several mechanisms have been postulated, including differential plaque morphology, alterations in the immune response, and hormonal variation and protection. Epidemiologic data suggest a link between inflammation and PAD and also reveal sex differences in lipid profiles associated with risk of PAD. In this review, we discuss available data on sex differences in PAD with additional focus on potential biological explanations for these differences. We also emphasize important knowledge gaps in this area, including under-representation of women in PAD clinical trials, to help guide future investigations and eliminate sex disparities in PAD.

Abstract
Background: Macrovascular complications occur very frequently in patients with type 2 diabetes mellitus (T2DM) with a high mortality rate, due to the development of cardiovascular disease (CVD), such as stroke, atherosclerosis acceleration, and atrial fibrillation. T2DM is a significant risk factor for CVD and has become the leading cause of death. The purpose of this study was to detect the early risk of macrovascular complications by using the ankle brachial index (ABI) as a marker. Methods: This study was an analytic study with a cross-sectional approach. The study population was patients with T2DM from several primary health care centers in Medan. In total, 89 subjects who met the inclusion and exclusion criteria were recruited with consecutive sampling. ABI was determined as the ratio of systolic blood pressure in the brachial artery to the posterior tibial artery after the subjects had been relaxed and felt comfortable in a supine position. Examination of vitamin D and lipid profile was derived from examination of venous blood. Data were processed using SPSS and analyzed with one-way ANOVA. Results: The study found that there was a relationship between LDL-C, triglyceride, and vitamin D (25OH-D) based on the ABI (p > 0.05). Conclusions: ABI can be used for an early detection of macrovascular complications. Apart from being easy to perform, ABI was non-invasive. Some other risk factors that can also be used to assess complications and have relationships with ABI were LDL-C, triglyceride, and vitamin D (25OH-D). Complications in T2DM patients can be prevented with reasonable blood sugar control and lifestyle changes. Education and motivation need to be given to patients so that they become more independent in controlling their disease and improving their quality of life.

Abstract
Background and Aims: Fibroblast growth factor 21 (FGF21), an emerging metabolic hepatokine, is associated with atherosclerosis. An interaction with sex has been described in various populations. We aimed to study whether sex modulates the relationship between FGF21 and subclinical carotid atherosclerosis in a diabetes-enriched multiethnic population of Singapore. We explore differences in intermediary mechanisms, in terms of hypertension, lipids, and inflammation, between FGF21 and atherosclerosis. Methods: We recruited 425 individuals from a single diabetes center in Singapore, and demographics, anthropometry, metabolic profile, FGF21, and carotid ultrasonography were performed. Multivariable logistic regression models were used to study the association between subclinical atherosclerosis and FGF21 adjusting for age, ethnicity, body mass index (BMI), hemoglobin A1c (HbA1c), systolic and diastolic blood pressures, and low-density lipoprotein (LDL)-cholesterol separately for males and females as two groups after an interaction test. Results: An interaction test assessing interaction by sex on the relationship between subclinical atherosclerosis and FGF21 showed a significant interaction with sex (Pinteraction = 0.033). In the female subgroup, significant independent associations of standardized lnFGF21 with subclinical atherosclerosis were seen, with 1 SD increment in lnFGF21 being associated with 1.48-fold (95% CI: 1.03, 2.12; p = 0.036) increase in risk. In the male subgroup, the association of subclinical atherosclerosis with standardized lnFGF21 was not significant [odds ratio (OR) (95% CI): 0.90 (0.63, 1.28); p = 0.553]. We found sex interactions with pulse pressure being significantly associated in females only and triglycerides and C-reactive protein being associated with males only. Conclusion: FGF21 is positively associated with subclinical carotid atherosclerosis in women, but not in men. The sex–racial patterns in the mechanisms by which FGF21 causes subclinical atherosclerosis needs to be explored in larger population-based studies and mechanistically studied in greater detail.

Abstract
Background Arterial diseases represent a severe public health problem in the 21st century. Although men have a higher overall prevalence, reports have suggested that women may exhibit atypical manifestations, be asymptomatic, and have hormonal peculiarities, resulting in worse outcomes and severe emergencies, such as acute limb ischemia (ALI). Objectives To analyze the morbidity and mortality profile of ALI emergencies in Brazil between 2008 and 2019. Methods An ecological study was carried out with secondary data from SIH/SUS, using ICD-10 code I.74 The proportions of emergency hospital admissions and in-hospital mortality rates (HMR) by gender, ethnicity, and age were extracted from the overall figures. P<0.05 was considered significant. Results From 2008 to 2019, there were 195,567 urgent hospitalizations due to ALI in Brazil, 111,145 (56.8%) of which were of men. Women had a higher HMR (112:1,000 hospitalizations) than men (85:1,000 hospitalizations) (p<0.05), and a higher chance of death (OR=1.36; p<0.05). Furthermore, mean survival was significantly higher among men (8,483/year versus 6,254/year; p<0.05). Stratified by ethnicity, women who self-identified as white (OR=1.44; p<0.05), black (OR=1.33; p<0.05), and brown (RR=1.25; p <0.05) had greater chances of death than men in the same ethnicity categories. Moreover, women over the age of 50 years had a higher chance of death, with a progressive increment in risk as age increased. Conclusions There was a trend to worse prognosis in ALI emergencies associated with women, especially in older groups. The literature shows that the reasons for these differences are still poorly investigated and more robust studies of this relevant disease in the area of vascular surgery are encouraged.

Abstract
Aims/hypothesis Previous meta-analyses have suggested that diabetes confers a greater excess risk of coronary heart disease, stroke, vascular dementia, and heart failure in women compared to men. While the underlying mechanism that explains such greater excess risk is unknown, in the current meta-analysis we hypothesized that we would find a similar sex difference in the relationship between diabetes and peripheral arterial disease (PAD). Methods PubMed MEDLINE, the Cochrane Database of Systematic Reviews, and Embase were systematically searched for prospective population-based cohort studies, with no restriction on publication date, language, or country. We included studies that reported the relative risk (RR), and its variability, for incident PAD associated with diabetes in both sexes. We excluded studies that did not adjust at least for age, and in which participants had pre-existing PAD. In cases where sex-specific results were not reported, study authors were contacted. Random-effects meta-analyses with inverse variance weighting were used to obtain summary sex-specific RRs and the women: men ratio of RRs for PAD. The Newcastle–Ottawa scale was used to assess study quality. Results Data from seven cohorts, totalling 2071,260 participants (49.8% women), were included. The relative risk for incident PAD associated with diabetes compared with no diabetes was 1.96 (95% CI 1.29–2.63) in women and 1.84 (95% CI 1.29–2.86) in men, after adjusting for potential confounders. The multiple-adjusted RR ratio was 1.05 (95% CI 0.90–1.22), with virtually no heterogeneity between studies (I2 = 0%). All studies scored 6–8, on the Newcastle–Ottawa scale of 0–9, indicating good quality. Eleven of the 12 studies that met review inclusion criteria did not report sex-specific relative risk, and these data were collected through direct correspondence with the study authors. Conclusion/interpretation Consistent with other studies, we found evidence that diabetes is an independent risk factor for PAD. However, in contrast to similar studies of other types of cardiovascular disease, we did not find evidence that diabetes confers a greater excess risk in women compared to men for PAD. More research is needed to explain this sex differential between PAD and other forms of CVD, in the sequelae of diabetes. In addition, we found that very few studies reported the sex-specific relative risk for the association between diabetes and PAD, adding to existing evidence for the need for improved reporting of sex-disaggregated results in cardiovascular disease research.

The age- and sex-specific composition of atherosclerotic plaques in vascular surgery patients. Atherosclerosis 2020; 310:1-10. [PMID: 32861960 DOI: 10.1016/j.atherosclerosis.2020.07.016] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2019] [Revised: 06/15/2020] [Accepted: 07/15/2020] [Indexed: 01/03/2023]
Abstract
BACKGROUND AND AIMS The sex- and age-related differences in the composition of iliofemoral atherosclerotic plaques are largely unknown. Therefore, the aim of the current study is to gain insight into plaque composition across strata of age and sex in a large cohort of vascular surgery patients. METHODS Peripheral atherosclerotic plaques of patients who underwent iliofemoral endarterectomy (n = 790) were harvested between 2002 and 2014. The plaques were semi-quantitatively analyzed for the presence of lipid cores, calcifications, plaque hemorrhages (PH), collagen, macrophage and smooth muscle cell (SMC) content, and quantitatively for microvessel density. Patients were stratified by age tertiles and sex. RESULTS Ageing was independently associated with rupture-prone iliofemoral plaque characteristics, such as higher prevalence of plaque calcifications (OR 1.52 (95%CI:1.03-2.24) p = 0.035) and PH (OR 1.46 (95%CI:1.01-2.09) p = 0.042), and lower prevalence of collagen (OR 0.52 (95%CI:0.31-0.86) p = 0.012) and SMCs (OR 0.59 (95%CI:0.39-0.90) p = 0.015). Sex-stratified data showed that men had a higher prevalence of lipid cores (OR 1.62 (95%CI:1.06-2.45) p = 0.025) and PH (OR 1.62 (95%CI:1.16-2.54) p = 0.004) compared to women. These sex-differences attenuated with increasing age, with women showing an age-related increase in calcifications (p = 0.002), PH (p = 0.015) and decrease in macrophages (p = 0.005). In contrast, men only showed a decrease in collagen (p = 0.043). CONCLUSIONS Atherosclerotic iliofemoral plaques derived from men display more rupture-prone characteristics compared to women. Yet, this difference is attenuated with an increase in age, with older women having more rupture-prone characteristics compared to younger women.

Increased Reintervention After Infrainguinal Revascularization for Chronic Limb-Threatening Ischemia in Women. Ann Vasc Surg 2020; 69:307-316. [PMID: 32561241 DOI: 10.1016/j.avsg.2020.06.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Revised: 05/15/2020] [Accepted: 06/05/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND The objective of this study was to determine if there are gender-based differences in major adverse limb events after revascularization for chronic limb-threatening ischemia (CLTI) and to identify potential associated factors. METHODS This was a single-center retrospective analysis of 151 patients who underwent infrainguinal revascularization for CLTI between April 2013 and December 2015. Only the first revascularized limb was included in patients with bilateral CLTI. Demographic data and clinical outcomes were collected using electronic medical records. RESULTS The mean age was 68.1 ± 12.1 years, and 55 of 151 (36%) were women. Women were less likely to carry a diagnosis of hyperlipidemia (60% vs. 83%; P = 0.003), less likely to be on a statin medication (58% vs. 81%; P = 0.004), and less likely to undergo an infrapopliteal revascularization (60% vs. 77%; P = 0.04) compared with men. There were no differences between genders with regard to the Society for Vascular Surgery Wound Ischemia and Foot Infection stage at presentation or utilization of open versus endovascular intervention. During the median follow-up time of 678 days (interquartile range, 167-1277 days), 48 of 151 patients (32%) underwent reintervention on the threatened limb and 23 of 151 patients (15%) underwent major amputation. Women were more likely than men to need reintervention (P = 0.02). There was no difference between genders for major amputation (P = 0.48) or overall survival (P = 0.65). In a multivariable Cox proportional hazards model for reintervention that included gender, preoperative body mass index, hyperlipidemia, preoperative anticoagulation, and ischemia score ≥2 (all P < 0.20 in univariate analysis), female gender (hazard ratio [HR], 1.96 [1.10-3.54]; P = 0.02) and hyperlipidemia (HR, 2.32 [1.07-5.03]; P = 0.03) were significantly associated with increased rates of reintervention. CONCLUSIONS Women undergoing lower extremity revascularization for CLTI were more likely to require reintervention compared with men but had similar rates of limb preservation. Further study is required to understand potential causative factors to improve treatment outcomes in women.

Abstract
BACKGROUND Sleep apnea and diabetes mellitus (DM) negatively impact cardiovascular health. One important indicator of cardiovascular health is the Ankle-Brachial Index (ABI). Either low ABI or high ABI are signs of peripheral vascular impairment. Impaired vascular health and DM, together, might provoke sleep apnea; however, information regarding these relationships is limited. Therefore, this study aimed to investigate the association between ABI, DM status, and severity of obstructive sleep apnea in people of Hispanic/Latino descent who are diverse in culture, environmental exposures, nativity, socioeconomic status, and disease burden. METHODS A cross sectional analysis from a multi-center epidemiologic study, Hispanic Community Health Study/Study of Latinos, was utilized and included 3779 participants (mean age 55.32 ± 7.67, females 57.9%). The sample was divided into 4 groups based on the American Diabetes Association diagnostic guidelines (no DM or DM), and the ABI status (normal and abnormal). Multiple linear regression analysis was used to determine the association of the four groups and other independent variables with severity of sleep apnea measured by apnea-hypopnea index. Kruskal-Wallis H test was used for comparisons between groups for the apnea-hypopnea index. The significant level was set at 0.01. RESULTS There were significant differences between groups in the mean of apnea-hypopnea index (P < 0.001; no DM + normal ABI = 5.42 ± 9.66, no DM + abnormal ABI = 7.11 ± 11.63, DM + normal ABI = 10.99 ± 15.16, DM + abnormal ABI = 12.81 ± 17.80). Linear regression showed that DM and abnormal ABI were significantly associated with severe sleep apnea (β = 3.25, P = 0.001) after controlling for age, sex, BMI, income, education, alcohol use, cigarette use, hypertension or related medication, stroke and statin use. CONCLUSION These findings suggest that people with DM and abnormal ABI were more likely to have high apnea-hypopnea index compared to the other groups. We observed gradual increasing in the severity of sleep apnea from low abnormality groups to high abnormality groups for Hispanic/Latino. Further work should elucidate the association of DM, abnormal ABI and sleep apnea with longer term outcomes, and replicate this work in different populations.

Abstract
Aim. Comparative assessment of the economic results of rivaroxaban/acetylsalicylic acid (ASA) combination and ASA monotherapy use in patients with coronary artery disease (CAD) and/or peripheral artery disease (PAD). Material and methods. Based on the results of a large international multicenter, placebo-controlled, randomized clinical trial COMPASS, a model that evaluated the clinical outcomes of rivaroxaban/ASA combination and ASA monotherapy was formed. The economic results using cost and cost-effectiveness analyses, and budget impact analysis for two years were also calculated. The analysis took into account both direct medical costs (expenses for treatment, hospitalization due to complications, rehabilitation) financed under the compulsory health insurance, as well as indirect costs (loss of GDP due to disability or death). The calculation was made by accounting 100,000 patients with CAD and/or PAD.Results. Modeling of clinical outcomes per 100,000 patients based on COMPASS results showed a decrease of stroke prevalence by 649 cases, myocardial infarction — 301 cases, amputations — 478 cases, cardiovascular mortality — 476 cases when using rivaroxaban/ASA combination compared with ASA monotherapy. The cost-effectiveness analysis showed that rivaroxaban/ASA combination has greater clinical efficacy and lower costs in comparison with ASA monotherapy. Budget impact analysis showed that the switching of 100,000 patients with CAD and/or PAD from ASA monotherapy to rivaroxaban/ASA combination leads to budget savings of 1,026 million rubles in two years. This is due to a decrease in the incidence of cardiovascular events.Conclusion. It was found that the use of a rivaroxaban/ASA combination in comparison with ASA monotherapy in patients with CAD and/or PAD can both decrease a number of complications and lead to cost savings, despite the initially higher cost pharmacotherapy.

Abstract
The global prevalence of diabetes is predicted to increase dramatically in the coming decades as the population grows and ages, in parallel with the rising burden of overweight and obesity, in both developed and developing countries. Cardiovascular disease represents the principal cause of death and morbidity among people with diabetes, especially in those with type 2 diabetes mellitus. Adults with diabetes have 2–4 times increased cardiovascular risk compared with adults without diabetes, and the risk rises with worsening glycaemic control. Diabetes has been associated with 75% increase in mortality rate in adults, and cardiovascular disease accounts for a large part of the excess mortality. Diabetes-related macrovascular and microvascular complications, including coronary heart disease, cerebrovascular disease, heart failure, peripheral vascular disease, chronic renal disease, diabetic retinopathy and cardiovascular autonomic neuropathy are responsible for the impaired quality of life, disability and premature death associated with diabetes. Given the substantial clinical impact of diabetes as a cardiovascular risk factor, there has been a growing focus on diabetes-related complications. While some population-based studies suggest that the epidemiology of such complications is changing and that rates of all-cause and cardiovascular mortality among individuals with diabetes are decreasing in high-income countries, the economic and social burden of diabetes is expected to rise due to changing demographics and lifestyle especially in middle- and low-income countries. In this review we outline data from population-based studies on recent and long-term trends in diabetes-related complications.

Abstract
Endovascular therapy is a viable treatment option for symptomatic peripheral artery disease (PAD). Diabetes mellitus is a major risk factor for PAD. We evaluated the long-term impact of diabetes mellitus in patients with PAD who underwent endovascular therapy. In this prospective registry of 765 patients who underwent endovascular therapy for symptomatic PAD, 560 had diabetes and 205 did not have diabetes. Propensity score matching (PSM) analysis was performed to adjust for any potential confounders. The primary endpoints were 5-year major adverse cardiac and cerebrovascular events (MACE) and major adverse limb events (MALE). After PSM analysis, baseline clinical and limb characteristics were similar in patients with diabetes and in patients without diabetes. Patients with diabetes had a higher rate of major hematoma (> 4 cm) (9.9% vs 3.3%, p = 0.038). At 5-year clinical follow-up, patients with diabetes and patients without diabetes had similar rates of MACE (20.7% vs 20.7%, log rank p = 0.989) and MALE (19.8% vs 24.5%, log rank p = 0.312), as well as the individual endpoints. In subgroup analysis adjusted by PSM, female patients with diabetes had a higher risk of MALE (hazard ratio 0.31, 95% CI 0.13–0.69, p = 0.004). Although there was a higher rate of major hematoma, patients with diabetes who underwent endovascular therapy had similar 5-year cardiac and vascular outcomes compared with patients without diabetes. Bleeding avoidance strategies, including optimal antiplatelet and antithrombotic therapy, and meticulous vascular access techniques, are needed in patients with diabetes to reduce the risk of bleeding and its deleterious impact on morbidity and mortality.

Abstract
BACKGROUND Prevalence of peripheral arterial disease increases with age and is related to increased morbidity and mortality. The clinical diagnosis includes the measurement of ankle-brachial index (ABI). AIMS To check the prevalence of abnormal ABI, and the value of physical examination of arterial system in detection of ABI < 0.9. METHODS We performed subgroup analysis of patients included in the PolSenior survey. We measured ABI, performed physical examination of arterial system, assessed laboratory and questionnaire factors related to atherosclerosis. Participants were divided according to ABI strata of < 0.9, 0.9-1.4 and > 1.4. Clinical score of abnormalities on physical examination was proposed. Using logistic regression, we obtained areas under the curve (AUC). RESULTS The mean age of 844 participants (53.3% men) was 74.7 (10.6) years. ABI < 0.9 was found in 20.3% participants and it was linked to history of myocardial infarction, hypertension and renal failure. In the entire group, 72.4% of subjects declared, that they were able to walk a distance of 200 m without interruption. Higher clinical score was associated with lower ABI. Full physical examination (AUC = 0.67) followed by examination of lower extremities (AUC = 0.65) showed strongest diagnostic value for PAD based on ABI. Neither ABI nor clinical examination was a good predictor of the inability to walk 200 meters without difficulties. DISCUSSION/CONCLUSIONS Full clinical examination, only moderately, adds to detection of PAD. The ability to walk 200 m is not a good measure of PAD in older subjects.

Abstract
Purpose: The purpose of the study is to present the preliminary audit and challenges of earliest cases of balloon angioplasty from Northwestern Nigeria. Materials and Methods: We present our first 25 cases of peripheral angioplasty in Northwestern Nigeria. The clinical diagnosis of peripheral artery disease was confirmed with Doppler ultrasound and angiography. Angioplasty was done either through femoral or brachial artery approaches. The patients were monitored for minimum of 6 months with serial clinical and Doppler ultrasound examinations. Results: Our patients consist of 19 males and 6 females. Their ages ranged from 20 to 80 years with a mean of 54 ± 17.5 years. There were 13 hypertensive and 15 diabetic patients while 5 patients have co-morbidities of diabetes and Hypertension. Although femoral antegrade route is the common access for angioplasty (14 out of 25), seven patients who were treated through the left brachial artery, six of them had either Type C or D aortoiliac disease in addition to distal lesions. At follow-up, 36% had limb amputation while one patient died a day after the procedure. Out of nine patients who had amputation, six are diabetic. Conclusion: Although more than half of them had improved blood flow with healing ischemic ulcers and reducing claudications, still substantial number of our patients often present late with severe peripheral artery disease. As a result, we had to resort to cumbersome arterial access and high amputation rate.

Abstract
Purpose: Little is known about the existence of potential gender disparities in
peripheral arterial occlusive disease. To our knowledge, this is the first
study to analyze differences attributed to gender in type-2 diabetic
patients with symptomatic peripheral arterial occlusive disease, with regard
to clinical presentations, risk factors and anatomical distributions of
atherosclerosis. Patients and methods: This study was conducted at King Abdullah University Hospital, Jordan.
Medical records of all diabetic (type-2) patients who presented with
symptomatic peripheral arterial occlusive disease in the period from January
2012 and November 2017 were reviewed, data were collected retrospectively.
In all, 364 patients (282 males and 82 females) were involved. Criteria for
diagnosis include the following Ankle-Brachial Index ⩽ 0.9 and intermittent
claudication or critical limb ischemia. Risk factors for atherosclerosis
(age, smoking and hypertension) and computed tomography-angiogram findings
were analyzed using Statistical Package for the Social Sciences. p < 0.05
was considered statistically significant. Results: The mean age was higher in females than males (67.61 vs 62.61 years; p =
0.001). Females had greater prevalence of uncontrolled diabetes compared to
males (HbA1c 9.07 in females vs 8.51 in males; p = 0.03). High density
lipoprotein was higher in females than males (1.02 vs 0.935; p = 0.009).
Females presented more with critical limb ischemia than intermittent
claudication in comparison with males (p = 0.017). Involvement of
superficial femoral artery, deep femoral artery and peroneal artery in
hemodynamic relevant atherosclerotic lesion was significantly higher in
females than males (p < 0.05). However, involvement of common iliac
artery with hemodynamic relevant atherosclerotic lesion was significantly
higher in males than females (p = 0.003). Conclusions: Clinical presentation, risk factors and anatomical distributions of
atherosclerosis among type-2 diabetic patients with symptomatic peripheral
arterial occlusive disease are different between males and females. When
compared to males, female patients presented more with critical limb
ischemia than intermittent claudication. Females showed higher age at
presentation, poor control of diabetes mellitus and higher level of high
density lipoprotein. Involvement of superficial femoral artery, deep femoral
artery and peroneal artery in hemodynamic relevant atherosclerotic lesion
were significantly higher in females than males. In contrast, common iliac
artery involvement with hemodynamic relevant atherosclerotic lesion was
significantly higher in males than females.

Abstract
Background Peripheral artery disease (PAD) is a major health problem in Saudi Arabia with considerable implications for morbidity and mortality. Many risk factors have been established for developing PAD, but the prevalence of these risk factors is variable from one country to another. Aim To identify the risk factors for PAD and study their prevalence in Jeddah, Saudi Arabia. Methods A retrospective chart review study was conducted in a tertiary center in Jeddah from July 2012 to September 2015. All patients with PAD were recruited into this study, and their data were analyzed using IBM SPSS. Correlation between PAD and various risk factors was studied using Spearman's coefficient. Results A total of 261 patients were recruited, of which 55% were males. Hypertension, diabetes type 2, and obesity were found among 34.2%, 33.3%, and 29.2% of the patients, respectively. About 45% had a history of previous vascular surgery, and amputation was performed in 6.9% particularly in legs. Hypertension and metabolic syndrome were the only risk factors that showed a significant correlation with PAD (P=0.039 and 0.040, respectively). Conclusion The most prevalent risk factors for PAD in Jeddah were hypertension, diabetes, obesity, and smoking. Hypertension and metabolic syndrome were the only risk factors significantly associated with PAD. Males were often more affected by PAD than females. The most commonly affected site was the lower limbs.

Abstract
OBJECTIVE: Hybrid surgical methods such as remote endarterectomy and endovascular revascularization are fluoroscopy-guided procedures successfully replacing conventional open surgery for treatment of peripheral artery disease (PAD). The aim of this study was to: (1) evaluate the dose parameters describing exposure of patients undergoing endovascular or hybrid revascularization of the lower limb (below the inguinal ligament); (2) compare the data available in the literature with the evaluations of patients' dose values and related factors for patients undergoing such procedures; (3) examine the correlation of doses with certain parameters; (4) estimate the peak skin dose and assess the potential for radiation-induced skin injuries during the procedures. METHODS: Data for 259 patients were extracted retrospectively and analyzed. The procedures were grouped by type of intervention, vascular approach, and level of complexity. The analyses included the correlation of dose values with the operating team. RESULTS: The air kerma-area product (KAP) and fluoroscopy time (FT) values greatly varied depending on the procedure type but also among patients undergoing the same procedure. The type of vascular access has the largest impact on patients' doses. The KAP and FT values for brachial artery were: 347 Gy.cm2 and FT: NA; for contralateral common femoral artery (CFA) approach: 207 Gy.cm2 and 153 s; e.g. significantly higher than for ipsilateral CFA: 96 Gy.cm2 and 78 s; for hybrid surgery: 77 Gy.cm2 and 41 s; and for ipsilateral retrograde popliteal approach: 61 Gy.cm2 and 53 s. The same tendency is observed for the peak skin dose (PSD) values: the highest are for brachial artery (2053 mGy) and contralateral CFA (1325 mGy) approach, followed by the ipsilateral CFA (748 mGy), hybrid surgery (649 mGy), and ipsilateral retrograde popliteal approach (566 mGy). CONCLUSION: Registered dose values and FT for the different procedures do not exceed the International Atomic Energy Agency (IAEA) proposed trigger values for patients' follow-up for radiation-induced skin injuries. The type of vascular access has the highest negative impact on radiation dose levels and resultant KAP, PSD, and FT values. There is a significant increase of the dose values with increase of the number of inserted stents and the level of complexity. This should be considered in planning, especially for patients who undergo multiple diagnostic and therapeutic procedures. ADVANCES IN KNOWLEDGE: This study gives a systematic understanding for patient radiation exposure in endovascular and hybrid revascularization of the lower extremities, thus far absent in the literature.

Accepting, active and in control: older women's experiences of ageing with peripheral arterial disease. AGEING & SOCIETY 2018.

Abstract
AbstractThe population of Australia is ageing, with women being the primary beneficiaries of this increase in longevity. Increasingly older individuals are being diagnosed with different chronic illnesses such as peripheral arterial disease (PAD) which causes blockages of the blood vessels in the legs resulting in pain, non-healing ulcers, immobility and the potential amputation of the threatened limb. PAD has been traditionally thought to affect men more than women. Resultingly, women have been under-represented in clinical trials of PAD and under-diagnosed in the health-care setting. However, it has recently been acknowledged that women are indeedmorelikely to suffer from PAD than men due to increased presence of disease and survival advantage. As such, very little is known about women's understanding of and the meaning they create of their experiences of PAD. Therefore, how older women with PAD experience the ageing process is the focus of this qualitative research project. Interviews were conducted with 11 women from Sydney, Australia aged over 65 years who had been diagnosed with PAD. The interviews were analysed using an inductive thematic analysis. Three manifest themes were constructed: independence and control, active and involved, and the acceptance of ageing. These findings emphasised the idea that despite the presence of a chronic illness and increased age, remaining independent and engaged with life was vital to these women's wellbeing. Their subjective experiences of ageing reflect the fact that by adapting to the physical, mental and social changes that come with growing older, the focus does not need to be on loss and decline but rather can be about the continuation of life that can be both positive and meaningful.

Abstract
Objective This population-based cohort study investigated the risk of developing peripheral arterial occlusive disease (PAOD) in patients with Bell’s palsy. Methods We used longitudinal claims data of health insurance of Taiwan to identify 5,152 patients with Bell’s palsy newly diagnosed in 2000–2010 and a control cohort of 20,608 patients without Bell’s palsy matched by propensity score. Incidence and hazard ratio (HR) of PAOD were assessed by the end of 2013. Results The incidence of PAOD was approximately 1.5 times greater in the Bell’s palsy group than in the non-Bell’s palsy controls (7.75 vs. 4.99 per 1000 person-years). The Cox proportional hazards regression analysis measured adjusted HR was 1.54 (95% confidence interval (CI) = 1.35–1.76) for the Bell’s palsy group compared to the non-Bell’s palsy group, after adjusting for sex, age, occupation, income and comorbidities. Men were at higher risk of PAOD than women in the Bell’s palsy group, but not in the controls. The incidence of PAOD increased with age in both groups, but the Bell’s palsy group to control group HR of PAOD decreased as age increased. The systemic steroid treatment reduced 13% of PAOD hazard for Bell’s palsy patients, compared to those without the treatment, but not significant. Conclusions Bell’s palsy appears to be associated with an increased risk of developing PAOD. Further pathophysiologic, histopathology and immunologic research is required to explore the underlying biologic mechanism.

Abstract
Diabetes mellitus (diabetes) is associated with significantly increased risk of peripheral vascular disease. Diabetes is classified as a coronary heart disease (CHD) risk equivalent, but it is unknown whether diabetes is a CHD risk equivalent for peripheral vascular disease. The objective was to evaluate the odds of peripheral arterial disease (PAD) or carotid artery stenosis (CAS) among participants with diabetes, CHD, or both, compared with participants without diabetes or CHD, in a nationwide vascular screening database. We hypothesized that diabetes and CHD would confer similar odds of PAD and CAS. METHODS A cross-sectional analysis of all eligible Life Line Screening Inc participants age 30 to 90 years with ankle brachial indices for PAD (ankle brachial index <0.9 in either leg) and carotid artery duplex ultrasonographic imaging for CAS (internal CAS ≥50%) was performed (N=3,522,890). RESULTS Diabetes and CHD were present in 372,330 (10.7%) and 182,760 (5.8%) of participants, respectively; PAD and CAS were present in 155,000 (4.4%) and 130,347 (3.7%) of participants. After multivariable adjustment, PAD odds were 1.56 (95% CI 1.54-1.59) and 1.69 (95% CI 1.65-1.73) for participants with diabetes or CHD, respectively. Participants with both diabetes and CHD had 2.75-fold increased odds of PAD (95% CI 2.66-2.85). Findings were similar for CAS; compared with no diabetes or CHD, CAS odds increased for participants with diabetes alone (1.53, 95% CI 1.50-1.56), CHD alone (1.72, 95% CI 1.68-1.76), and both diabetes and CHD (2.57, 95% CI 2.49-2.66). Findings were consistent for women and men. CONCLUSION In a large database of more than 3.5 million self-referred participants, diabetes was a CHD risk equivalent for PAD and CAS, and participants with comorbid diabetes and CHD had an especially robust association with PAD and CAS. Counseling regarding screening and prevention of peripheral vascular disease may be useful for patients with diabetes.

Abstract
Background Metabolic syndrome is defined by a clustering of cardiovascular risk factors and is associated with a heightened inflammatory state. A raised serum high-sensitivity C-reactive protein, a marker of inflammation, is also known to associate with cardiovascular risk. We have investigated the relationship between the presence of metabolic syndrome and serum high-sensitivity C-reactive protein concentration in a large representative Persian population cohort without a history of cardiovascular disease. Methods The MASHAD study population cohort comprised 9778 subjects, who were recruited from the city of Mashhad, Iran, between 2007 and 2008. Several cardiovascular risk factors were measured in this population without cardiovascular disease. Individuals were categorized into quartiles of serum high-sensitivity C-reactive protein concentration: first quartile – 0.72 (0.59–0.85) (median [range]) mg/L, second quartile – 1.30 (1.14–1.4) mg/L, third quartile – 2.29 (1.92–2.81) mg/L and fourth quartile – 6.63 (4.61–11.95) mg/L, respectively. The prevalence of metabolic syndrome in each quartile was determined using either International Diabetes Federation or Adult Treatment Panel III criteria. Results The prevalence of metabolic syndrome was highest in the fourth quartile for serum high-sensitivity C-reactive protein (1220 subjects [50.0%]), and significantly higher than that in the first quartile (reference group) (634 subjects [25.9%]) ( P < 0.001). A positive smoking habit (OR, 1.47 [1.26–1.70], P < 0.001) and the presence of either metabolic syndrome-International Diabetes Federation (OR, 1.35 [1.18–1.55], P < 0.001) or metabolic syndrome-ATPIII (OR, 1.40 [1.18–1.50], P < 0.001) were strong predictors of a fourth quartile for serum high-sensitivity C-reactive protein concentration. Conclusions There was a significant association between high concentrations of serum high-sensitivity C-reactive protein and the presence of metabolic syndrome among individuals without a history of cardiovascular disease in our Persian cohort.

Abstract
Some believe that certain patients with intermittent claudication may be unsuitable for supervised exercise therapy (SET), based on the presence of comorbidities and the possibly increased risks. We conducted a systematic review (MEDLINE, EMBASE and CENTRAL) to summarize evidence on the potential influence of diabetes mellitus (DM) on the response to SET. Randomized and nonrandomized studies that investigated the effect of DM on walking distance after SET in patients with IC were included. Considered outcome measures were maximal, pain-free and functional walking distance (MWD, PFWD and FWD). Three articles met the inclusion criteria ( n = 845). In one study, MWD was 111 meters (128%) longer in the non-DM group compared to the DM group after 3 months of follow-up ( p = 0.056). In a second study, the non-DM group demonstrated a significant increase in PFWD (114 meters, p ⩽ 0.05) after 3 months of follow-up, whereas there was no statistically significant increase for the DM group (54 meters). On the contrary, the largest study of this review did not demonstrate any adverse effect of DM on MWD and FWD after SET. In conclusion, the data evaluating the effects of DM on SET were inadequate to determine if DM impairs the exercise response. While trends in the data do not suggest an impairment, they are not conclusive. Practitioners should consider this limitation when making clinical decisions.

Abstract
OBJECTIVES To evaluate outcomes after endovascular treatment of patients with aneurysmal or occlusive vasculopathy in HIV-infected patients. METHODS Retrospective analysis of a prospective database of treatment outcomes in patients with HIV related vasculopathies between April 2005 and September 2015. RESULTS Sixty HIV patients presented with post-traumatic pseudoaneurysm formation (n = 7), aneurysmal disease (n = 24) or occlusive disease (n = 29 (48%)). The majority were male (42/60 (70%)), with a mean age of 43.9 years (SD ± 12.6). All seven patients with a post-traumatic pseudoaneurysm were treated by insertion of a covered stent (n = 6) or coiling (n = 1). All were successfully treated at 30 days, but only one patient returned for late surveillance. 23/24 patients who underwent insertion of a stent graft/covered stent for aneurysmal disease returned for 30 day review (one asymptomatic stent graft occlusion). Only 11 patients attended for late surveillance; 9/11 were asymptomatic with patent stent grafts. Late stent occlusion occurred in two (no further action (n = 1), major limb amputation (n = 1). In the 29 patients who underwent endovascular treatment for occlusive disease, 9 (31%) had immediate treatment failure (including 8 amputations (28%)). Of the sixteen who returned for serial review, 8 (50%) suffered further complications including 4 amputations. Overall, 12/29 treated patients (41%) ultimately underwent amputation. CONCLUSIONS In the immediate short term, an 'endovascular first' strategy was associated with good outcomes in HIV patients with aneurysmal disease. By contrast, outcomes were poor in HIV patients with occlusive disease. Whether this relates to the underlying natural history of HIV occlusive vasculopathies remains unclear. One major problem in trying to formulate meaningful management strategies is a generalised reluctance for HIV patients to return for surveillance.

Abstract
BACKGROUND Peripheral artery disease (PAD) is highly prevalent and associated with significant morbidity and mortality, but sex-based differences are incompletely understood. We sought to define the associations between PAD and physical outcome measures and to determine if these associations differed by sex in the Chronic Renal Insufficiency Cohort. METHODS Among 3,543 participants, we assessed the cross-sectional relationship between PAD severity defined by ankle-brachial index; and (1) physical activity (metabolic equivalent [MET]-hr/wk), (2) walking pace (slow versus medium and/or fast), and (3) physical function (12-item Short Form Health Survey [SF-12]) at baseline. RESULTS In a multivariable linear regression model, PAD severity was not associated with physical activity defined by total MET-hr per wk in men or women (P = 0.432). However, PAD severity was significantly associated with walking activity (P = 0.037), although this relationship did not differ by sex (P = 0.130). Similarly, PAD severity was significantly associated with walking pace (P < 0.001), although this relationship did not differ by sex (P = 0.086). In contrast, there was an independent association between PAD severity and SF-12 (P = 0.018), with a significant interaction by sex (P < 0.001). CONCLUSIONS These data suggest that tools used to evaluate the functional consequences of PAD should focus on walking activity and walking pace, as well as physical function, where sex-specific associations should be accounted for.

Temporal profiles of blood pressure, circulating nitric oxide, and adrenomedullin as predictors of clinical outcome in acute ischemic stroke patients. Mol Med Rep 2016; 13:3724-34. [PMID: 27035412 PMCID: PMC4838158 DOI: 10.3892/mmr.2016.5001] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2015] [Accepted: 02/18/2016] [Indexed: 12/12/2022] Open
Abstract
Stroke remains an important health and social challenge. The present study investigated whether blood pressure (BP) parameters and circulating levels of nitric oxide metabolites (NOx) and adrenomedullin (AM) may predict clinical outcomes of stroke. Patients (n=76) diagnosed with acute ischemic stroke were admitted to the stroke unit and clinical history data and monitored parameters were recorded. Blood plasma was collected at days 1, 2, and 7 to measure NOx and AM levels. Infarct volume, neurological severity [on the National Institutes of Health Stroke Scale (NIHSS)], and functional prognosis (on the Rankin scale) were measured as clinical outcomes. Patients with higher BP had more severe symptoms (NIHSS >3; P<0.01) and BP variability predicted neurological severity and growth of infarct volume. NOx values were significantly lower in stroke patients than in healthy controls (P<0.01). An increase in NOx levels from day 1 to day 2 was beneficial for the patients as measured by NIHSS at 7 days and 3 months, and by Rankin at 3 months [odds ratio (OR), 0.91] whereas a steep increase from day 2 to day 7 was detrimental and associated with an increase in infarct volume (OR, 35.3). AM levels were significantly higher in patients at day 1 and 2 than in healthy individuals (P<0.01) and these levels returned to normal at day 7. Patients with high AM levels at day 2 had significantly higher NIHSS scores measured at day 1 (P<0.05) and 7 (P<0.01). A receiving operating characteristic curve analysis identified that AM levels at day 2 of >522.13 pg/ml predicted increased neurological severity at day 7 (area under the curve=0.721). Multivariate logistic regression indicated that AM levels at day 2 predicted increased neurological severity at 7 days and at 3 months. BP parameters and changing levels for NOx and AM predicted long-term clinical outcomes as measured by infarct volume, neurological severity scale, and functional prognosis.

Abstract
OBJECTIVE Prevalence of peripheral arterial disease is equal in men and women. However, women seem to suffer more from the burden of disease. Current studies on gender-related outcomes following supervised exercise therapy (SET) for intermittent claudication (IC) yield conflicting results. METHODS A follow-up analysis was performed on data from the 2010 Exercise Therapy in Peripheral Arterial Disease (EXITPAD) study, a multicenter randomized controlled trial including IC patients receiving SET or a walking advice. The SET program was supervised by physiotherapists and included interval-based treadmill walking approximating maximal pain combined with activities such as cycling and rowing. Patients usually started with three 30-minute sessions a week. Training frequency was adapted during the following year on the basis of individual needs. The primary outcome was gender differences regarding the change in absolute claudication distance (ACD) after SET. ACD was defined as the number of meters that a patient had covered just before he or she was forced to stop walking because of intolerable pain. Secondary outcomes were gender differences in change of functional walking distance, quality of life, and walking (dis)ability after SET. Walking distances were obtained by standardized treadmill testing according to the Gardner-Skinner protocol. Quality of life was measured by the 36-Item Short Form Health Survey, and walking (dis)ability was determined by the Walking Impairment Questionnaire (WIQ). Measurements were performed at baseline and after 3, 6, 9, and 12 months. Only patients who met the 12-month follow-up measure were included in the analysis. RESULTS A total of 113 men and 56 women were available for analysis. At baseline, groups were similar in terms of clinical characteristics and ACD walking distances (men, 250 meters; women, 270 meters; P = .45). ACD improved for both sexes. However, ACD increase was significantly lower for women than for men during the first 3 months of SET (Δ 280 meters for men vs Δ 220 meters for women; P = .04). Moreover, absolute walking distance was significantly shorter for women compared with men after 1 year (565 meters vs 660 meters; P = .032). Women also reported less on several WIQ subdomains, although total WIQ score was similar (0.69 for men vs 0.61 for women; P = .592). No differences in quality of life after SET were observed. CONCLUSIONS Women with IC benefit less during the first 3 months of SET and have lower absolute walking distances after 12 months of follow-up compared with men. More research is needed to determine whether gender-based IC treatment strategies are required.

Abstract
This nationwide population-based retrospective cohort study was used to evaluate the association between pneumoconiosis and peripheral arterial disease (PAD). We identified 3374 patients with pneumoconiosis from the catastrophic illness registry who were newly diagnosed from 2000 to 2005; 13,496 patients without pneumoconiosis from Longitudinal Health Insurance Database 2000 (LHID2000) were randomly frequency matched according to sex, age, and index year and used as a nonpneumoconiosis group. Multivariate Cox proportional hazards regression was used to calculate adjusted hazard ratios (HRs) of PAD in the pneumoconiosis group compared with the nonpneumoconiosis group. The mean follow-up years were 7.44 years in the pneumoconiosis group and 8.17 years in the nonpneumoconiosis group. The incidence density rate of PAD was 1.25 times greater in the pneumoconiosis group than in the nonpneumoconiosis group (8.37 vs 6.70 per 1000 person-years). After adjusting for sex, age, and comorbidities, the adjusted HRs of PAD for the pneumoconiosis group were 1.30 (95% CI = 1.08-1.57), compared with the nonpneumoconiosis group. The combined impacts of patients with pneumoconiosis and diabetes, hyperlipidemia, hypertension, ischemic heart disease, chronic obstructive pulmonary disease, and asthma showed a significant by joint association with PAD risk compared with patients with no pneumoconiosis and no counterpart comorbidity. Patients with pneumoconiosis have an independently higher risk of developing PAD. Physicians should include pneumoconiosis in evaluating PAD risk.
