Objective

Venous leg ulcers (VLU) are chronic, recurrent and have a significant impact on the patients’ health- related quality of life (HRQoL). This study assessed the association of patient-specific factors on the HRQoL of patients with chronic venous leg ulcers.

Materials and Methods

The study included 21 males and 21 females aged 18 years and above, with chronic VLU. Data on demographics, education, occupation, per capita income, duration of ulcer were subjectively recorded. The socio-economic status was scored based on the Modified Kuppuswamy scale 2019, ulcer severity was assessed using M.A.I.D. Scale and the HRQoL of the patients were assessed using the 36-Item Short-Form Health Survey Version 1.0. The differences in the mean HRQoL scores between patients based on their gender and socio-economic class were assessed using an unpaired sample t-test. The association of age, severity, duration of the ulcer with the HRQoL were assessed using Pearson's correlation. A probability value of < 0.05 was considered statistically significant.

Results

There were 21 (50%) males and 21 (50%) females with a mean age of 55.45 ± 7.73 years. The mean duration of ulcers was 7.26 ± 3.34 months and the mean ulcer severity score was 2.16 ± 0.96. Role limitations due to the physical health were found to be most impacted due to the disease condition with the least mean score of 26.78 ± 31.90 %. There were no significant differences in the mean scores of the physical and the mental components of HRQoL based on gender but there were significant differences based on socio-economic status. The lower the socio-economic status, the poorer the HRQoL. Age, severity of ulcers and ulcer duration had a significant negative correlation with HRQoL.

Conclusion

The study observed a low HRQoL of patients in physical aspects reflecting on the extensive limitation on the performance of daily physical activities. Patient-specific factors such as age, socio-economic status, severity, and chronicity of ulcers were found to influence HRQoL.

Introduction

Intermittent claudication (IC) is the most common symptom of peripheral arterial disease (PAD) which presents as a consequence of muscle ischaemia resulting from the atherosclerotic obstruction to arterial flow. High-quality evidence (Lane et al., 2017) shows that exercise programmes provide important benefits compared with usual care in improving pain-free and maximum walking distance in people with IC, but do not improve ankle-brachial pressure index (ABPI).

Methods

Retrospective data were analysed to examine walking and ABPI outcomes for participants who completed a 12-week course of supervised or home-based exercise. All participants had a history of IC.

Results

46 participants (mean age 69±11 years; 76% male; 29% current smokers) referred for exercise were assessed, completed a 12-week course of exercise (home-based or supervised) and subsequently attended for re-assessment. Claudication onset distance (COD) increased by 363% (mean improvement 344.7 ± 265.1m; p < .001) and peak walking distance (PWD) by 324.4% in the supervised exercise group; COD increased by 30.6% (mean improvement 32.8 ± 57.2 m; p = 0.026) and PWD by 31.5% in the home-based exercise group. Resting ABPI for the total cohort significantly improved from 0.82 ± 0.25 at A1 to 0.88 ± 0.25 at A2 (p = 0.027).

Discussion

A 12-week course of supervised exercise results in significantly greater walking distance outcomes (COD and PWD) than unmonitored home-based exercise. In contrast with previous findings (Lane et al. 2017), this retrospective study demonstrated a significant improvement in resting ABPI with both supervised exercise as well as home-based exercise.

Conclusion

A 12-week programme of exercise favourably influenced walking and ABPI outcomes for patients with IC. Both home-based exercise and supervised individualised exercise increased walking distances, but the magnitude of the improvement in walking outcomes was greater in individuals who attended supervised exercise therapy.

Marfan syndrome is one of the most common inherited connective tissue disorders that affects the heart, eyes, blood vessels, and bones. It occurs in approximately 1-2 per 10,000 individuals annually. Many patients with Marfan syndrome eventually develop aortic wall abnormalities, often resulting in aortic dilatation, which increases the risk of acute aortic dissection. Recent studies involving SARS-CoV-2 propose that individuals with connective tissue disorders such as Marfan syndrome can have additional associated conditions that could impose a higher risk for morbidity and mortality from SARS-CoV-2. The purpose of this article is to discuss the interrelationship between Marfan Syndrome, Acute Type A Aortic Dissection in a patient with Sars-CoV-2 infection. Pertinent review of these conditions, diagnostic findings, treatment, and the patient's clinical course will be discussed. There is minimal research focused on the connection between this novel virus, Marfan Syndrome, and compounding risk for aortic dissection.

Background and Objective

Hemodynamic changes are among the common complications after coronary artery bypass graft (CABG) surgery. Incentive spirometry (IS) and deep breathing exercises (DBEs) are widely used in patients undergoing CABG surgery. The aim of the present study was to compare the effect of IS and DBEs on hemodynamic and oxygenation parameters of patients undergoing CABG surgery.

Methods

This is a clinical trial that was performed on 40 patients with heart disease who were candidates for coronary artery bypass graft surgery. Participants were selected using convenience sampling and then randomly divided into two groups. One day before surgery, one group was taught how to perform DBE and the other group was taught how to use IS in practice. Hemodynamic and oxygenation indices were measured and recorded before the intervention, the first, second, and the third day after the intervention. Data analysis was carried out using SPSS ver.16 and descriptive and inferential statistical tests.

Results

The mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) on the first day after the intervention in patients undergoing the IS group was significantly higher than the DBE group (p<0.05). On the third day after the intervention, the mean arterial oxygen saturation (SaO₂) in patients of the IS group was significantly higher than the DBE group and the mean respiratory rate (RR) in patients in the IS group was significantly lower than the DBE group (p <0.05). However, there was no significant difference between the two groups in terms of other indices (p> 0.05).

Conclusion

The results showed that IS has a greater effect on hemodynamic and oxygenation indices of patients undergoing CABG compared to DBE, so, it is recommended to use IS to improve hemodynamic and oxygenation indices in these patients.

Background

Deep vein thrombosis (DVT) is a common and preventable complication in patients with lower extremity trauma. DVT prediction is considered to be necessary.

Purpose

This study aimed to compare the Autar DVT risk assessment scale with modified Wells criteria in predicting DVT by nurses in patients with lower extremity trauma.

Methods

Patients with lower extremity trauma patients who met the requirements for this study were assessed by both the Autar and Wells tools for DVT risk assessment during the first 24 hours after their admission. Statistical analysis was performed using SPSS 18.

Results

There was a significant and direct statistical relationship between the results of risk assessment of these two tools based on Pearson correlation (r= 0.731, P<0.0001). Kappa coefficient between the two was 53%. Sensitivity and specificity of the Autar scale were 100% and 68%, respectively, which revealed a higher degree of sensitivity than that of the Wells criteria.

Conclusion

Although the results of DVT prediction for the Autar scale and modified Wells criteria were consistent, the Autar DVT risk assessment scale showed higher sensitivity. Therefore, it is recommended that the Autar scale be used to achieve more precise DVT predictions.
