Background

Frailty syndrome is prevalent among many patients experiencing intermittent claudication symptoms. Considering that components of the frailty syndrome can affect both physical and psychological functions, it is likely that barriers to physical activity are heightened in these individuals.

Aim

To analyze the association between barriers to physical activity and frailty in patients with symptomatic peripheral artery disease (PAD).

Methods

This cross-sectional study included 216 patients with symptomatic PAD (64.8% men, 65.6±9.4 yrs.). Nine personal and 8 environmental barriers to physical activity were investigated through a questionnaire on barriers to practicing physical activity in patients with intermittent claudication. Frailty was defined according to Fried et al. (2001) criteria which included unintentional weight loss, exhaustion, low grip strength, slow walking speed, physical inactivity. Three or more criteria defined frail, one or 2 criteria defined pre-frail, and absence of criteria defined non-frail. Data are presented as median (interquartile range).

Results

Frail and pre-frail patients have more barriers than non-frail patients [frail: 11 (4); pre-frail: 10 (6); non-frail: 8 (7), p = 0.001]. Absence of a companion for physical activity, lack of knowledge and uncertainty about the benefits of physical activity, pain induced by walking and presence of obstacles that worsen leg pain were associated with frail and pre-frail status, independent of sex, age, ankle-brachial index, and total walking distance.

Conclusion

Patients with PAD who are frail and pre-frail have more barriers to physical activity than non-frail patients. Therefore, specific interventions promoting PA are essential for these patients to improve their health outcomes.

Aim

To identify the factors associated with thrombosis in dialysis patients.

Background

Thrombosis is a leading cause of vascular access failure in dialysis patients. Numerous risk factors contribute to thrombosis in this population.

Methods

A systematic search was conducted across international databases using standardized keywords. The quality of the selected studies was assessed using the STROBE and CONSORT checklists. The findings were summarized in a Garrard table. Meta-analysis was performed using CMA software. The study adhered to the guidelines outlined in the PRISMA statement.

Results

A total of 180 articles were reviewed. The odds ratio for thrombosis in patients with arteriovenous grafts compared to arteriovenous fistulas was 10.93 (95 % CI: 9.35-12.78), demonstrating statistical significance (P = 0.001). Similarly, hemodialysis patients had an odds ratio of thrombosis 3.60 times higher than non-hemodialysis patients (95 % CI: 3.54-4.19), with statistical significance (P = 0.001). Patients undergoing single-stage basilic vein transposition had a 1.89 times higher risk of thrombosis compared to those undergoing two-stage transposition (95 % CI: 1.04-3.46), also demonstrating statistical significance (P = 0.038).

Conclusions

Thrombosis in patients with end-stage renal disease undergoing dialysis was significantly associated with various factors, including graft access, single-stage basilic vein transposition, and hemodialysis. Additional contributing factors to thrombosis included diabetes, elevated homocysteine levels, female gender, age over 50, access location, and low access blood flow velocity. The analysis revealed a higher incidence of thrombosis in end-stage renal disease patients undergoing hemodialysis compared to those not undergoing dialysis, as well as in patients with arteriovenous grafts compared to those with arteriovenous fistulas. These findings underscore the importance of recognizing and managing these risk factors to prevent thrombotic events and enhance patient care within the dialysis setting.

Background: The Centers for Medicare and Medicaid Services consider the 30-day hospital readmission rate an outcome of care measure; a high rate is associated with high-cost and bed utilization. Purpose: The Division of Vascular Surgery at a large academic medical center implemented a 15-week quality improvement project in the fall of 2022 to reduce readmissions among patients deemed high-risk for readmission and discharged to home. Methods: The discharging provider utilized the “HOSPITAL Score for Readmission” tool to identify patients at high-risk for unplanned 30-day readmission to receive the intervention, which included follow-up with a primary care provider (PCP) within two weeks of hospital discharge to address non-surgical medical conditions that may have been exacerbated during the hospital stay. A hospital based transitional care clinic bridged medical care for identified patients without an established PCP or whose PCP could not accommodate an appointment until PCP assumption of care. Discharging providers included 11 nurse practitioners and 2 surgery residents; each received a one-on-one educational teaching session and a weekly reminder e-mail through week 9. Results: A total of 158 vascular surgery patients (low and high-risk) were discharged home over 15 weeks with 30 patients (19%) having an unplanned readmission within 30-days from discharge. Adherence issues with the intervention among staff allowed for the high-risk group to be divided into those who did not receive the intervention versus those who did. The high-risk patients who did not receive the intervention had a higher readmission rate (30.4%) than the high-risk patients who did receive the intervention (21.4%). Conclusions: Numerous acute and chronic medical problems were treated at the PCP/transitional care clinic visits, which may have contributed to the reduction in rate of readmissions occurring within 30-days for those patients. Increased usage of the transitional care clinic identified a gap that patients continue to require assistance with establishing care with a PCP and further process change in the future is needed to ensure successful transition for all patients.

Background

Numerous military soldiers have lost limbs as a result of the Syrian War. While there are variations between trauma-related amputations in military and civilian populations, both scenarios result in life-changing injuries.

Objective

To explore the relationship between body image, self-esteem, and quality of life (QOL) domains following trauma-related major amputation.

It will be the first study in Syria on the correlation between self-esteem and body image. It will help improve our quality of care to meet patient needs and increase well-being, which in turn will help to address body image, self-esteem, and QOL.

Method

A cross-sectional study that recruited 235 soldiers with amputations in two centers and two military hospitals in Latakia and Tartous. Patients were given an 81-item questionnaire that included the Amputee Body-Image Scale (ABIS), the Rosenberg Self-esteem (RSE) scale, the WHOQOL-BREF questionnaire, and unidimensional pain measures. The ANOVA test, a student's t-test, multiple linear regression, internal consistency, and test-retest reliability were utilized for statistical analysis.

Results

There was a strong relationship between body image, self-esteem, and QOL, with the presence of body image concerns significantly associated with lower self-esteem scores and lower QOL scores (p=0.001). Patients with phantom pain sensation had significantly reduced self-esteem (p =0.001), greater body image concerns (p =0.001), and lower scores in all domains of QOL. We found that body image and self-esteem impacted the psychological, social, and environmental domains. After controlling for pain level and number of co-morbid conditions, body image and self-esteem did not predict WHOQOL-BREF scores, with the exception of the environmental domain, where no pain and low self-esteem predicted better environmental domain scores.

Conclusion

Patients' body image and self-esteem were greatly impacted by lower-limb amputations. Additionally, phantom pain further impacted self-esteem, body image, and QOL. The image of the body had a profound effect on psychological, social, and environmental domains, and self-esteem was influenced by almost all aspects of QOL.

Background

Walking as a treatment is recommended for people with intermittent claudication (IC), but participation tends to be poor. Walking treatment beliefs, as defined by the Theory of Planned Behaviour (TPB) are associated with walking behavior, so assessing and designing interventions targeting walking treatment beliefs are crucial. To assess walking treatment beliefs in people with IC in Gujarat, a translated, culturally adapted questionnaire that assesses the four TPB constructs (attitude, subjective normative beliefs, perceived behavioral control beliefs, and intention to walk) is required.

Aim

To translate and cross-culturally assess the content validity and face validity of a Gujarati version of a TPB questionnaire that assesses walking treatment beliefs.

Materials and methods

A forward-backward translation of the 12-item TPB questionnaire was applied using a standardized approach. The translated versions were compared with the original questionnaire, and ten experts, rated each item according to: clarity, semantic, appropriateness, and cultural relevance. Content Validity Index (CVI), item level content validity (I-CVI), Scale –content validity index (S-CVI/Ave), and universal agreement (UA) were computed to summarize the overall content validity of the questionnaire as well as a proportion of agreement with content experts. Face validity was assessed using a think-aloud approach with ten patients with IC. This cognitive interviewing approach (think-aloud approach) asked participants to describe their thoughts whilst completing the questionnaire. Responses were analyzed thematically.

Results

There was complete agreement between experts for 9/12 items (I-CVI=1.00), leading to an overall agreement (S-CVI/Ave) of 0.98. For face validation, at least 50% of the participants had no significant problems with any question in the questionnaire. Most problems participants encountered were straightforward, such as re-reading some questions or considering the questions carefully before answering.

Conclusion

The Gujarati TPB questionnaire had excellent content validity and was comprehensible and answerable by the majority of our participants with IC and, therefore, had good face validity; this will enable walking treatment beliefs to be assessed in people with IC.

Background

Exercise therapy is a recognized non-pharmacological intervention for peripheral arterial disease (PAD); however, the effects of combined exercise remain under investigation. This study aimed to compare the effects of a 6-month combined supervised exercise program (SUP) with a usual care (UC) approach on walking ability, physical fitness, and peripheral blood flow in people with PAD and claudication.

Methods

Twenty-three male participants (Age=64.1 ± 6.2years and ABI=0.58±0.07) with PAD and claudication were assigned to either the SUP group (n = 10), engaging in structured supervised treadmill walking combined with three resistance exercises, three times a week, or the UC group (n = 13), receiving advice to walk. The primary outcome measure was walking ability, with assessments conducted at baseline (M0), after 3 months (M3), and 6 months (M6).

Results

After the 6-month intervention, the SUP group exhibited significant improvements in absolute claudication time (ACT, p = 0.045), maximal walking time (MWT, p = 0.045), maximal walking distance (MWD, p = 0.027), and pause duration (p = 0.045) during the 6-minute walk test (6MWT), when compared to the UC group. Over time, a significant increase in walking speed during the 6MWT (Speed_6MWT, p = 0.001) and walking speed without claudication (Speed_NoC, p < 0.001) was found, although no significant differences were found between the groups. The SUP group increased by 0.8 km/h in both Speed_6MWT and Speed_NoC, while the UC group increased by 0.3 km/h and 0.6 km/h, respectively. Despite claudication consistently occurring at the same time, the SUP group demonstrated an improved tolerance to pain or a better understanding of pain, enabling them to walk longer distances at higher speeds. A positive effect of SUP was found for chair sit-and-reach test (p = 0.023), percentage of fat mass (p = 0.048), fat-free mass (p = 0.040), and total body water (p = 0.026), suggesting potential benefits attributed to the resistance strength exercises.

Conclusion

A 6-month combined treadmill and resistance exercise program improved walking ability, walking speed, lower body and lower back flexibility, and body composition in people with PAD and claudication.

Introduction

It is well known that peripheral artery disease (PAD) and coronary artery disease (CAD) coexist and therefore, patients diagnosed with PAD have an increased chance of developing concomitant CAD. CAD-related complications could be a leading cause of postoperative mortality in individuals with PAD undergoing vascular surgery. We present a case series of 48 patients who underwent coronary angiography before vascular surgery and an updated review of previous reports to determine the prevalence of concomitant CAD in a convenience sample of Iranian patients.

Methods

This cross-sectional study was performed on 48 patients with confirmed PAD admitted to Imam Ali Hospital, affiliated with the Kermanshah University of Medical Sciences (KUMS), Kermanshah Province, Iran. A vascular surgeon diagnosed PAD based on the patient's symptoms, Doppler ultrasound, and CT angiography (CTA). All patients underwent coronary angiography to determine if they also had CAD. We defined significant CAD as a ≥70% luminal diameter narrowing of a major epicardial artery or a ≥50% narrowing of the left main coronary artery.

Results

Of 48 patients, 35 (72.9%) were male, 13 (27.1%) were female, and the mean age was 64.18±12.11 years (range, 30 to 100 years). The incidence of CAD in patients with PVD was 85.42% (41/48). The patients with CAD were more likely to be hypertensive than those without CAD (80.5 vs. 14.3, p-value<0.001). Of 41 patients with CAD, 9 (22.0%) had one-vessel disease, 10 (24.3%) had two-vessel disease, and 22 (53.7%) had three-vessel disease.

Conclusion

Hypertension was a significant risk factor for CAD. Patients with hypertension and multiple major coronary risk factors scheduled for PVD surgery should be carefully evaluated for concomitant CAD.
