Comparative effects of fascial distortion model with and without neuromuscular inhibition technique on pain, range of motion and quality of life in patients with piriformis syndrome

PURPOSE

This study aimed to compare the effects of the fascial distortion model (FDM) with and without neuromuscular inhibition technique (NIT) on pain, range of motion and quality of life in patients with piriformis syndrome.

METHODS

The study was a randomized controlled trial and 54 participants were randomly allocated by lottery method into two groups. Group A (27 participants) received the FDM with NIT and Group B (27 participants) received the FDM alone. The patients were treated for six weeks, three sessions each week on alternate days. Outcome measurements were taken before the first treatment session and after the last (sixth week) session. Numeric Pain Rating Scale, Sciatica Bothersomeness Index (SBI), and Goniometer were used as outcome measures. SPSS version 25 was used for statistical analysis.

RESULTS

Data was normally distributed by the Shapiro-Wilk Test. Statistically significant improvements (p < 0.05) were observed in the FDM with NIT than in FDM alone. Both groups show significant results in all outcome measures with paired sample t-tests (p < 0.05).

CONCLUSION

This study concluded that participants with piriformis syndrome show more improvement in the FDM with NIT than the FDM group alone.

The effects of an 8-week dynamic neuromuscular stabilization exercise on pain, functional disability, and quality of life in individuals with non-specific chronic low back pain: a randomized clinical trial with a two-month follow-up study

BACKGROUND

Low back pain (LBP) is a common disorder and is considered one of the leading causes of disability worldwide, resulting in adverse health, social, and economic outcomes. This study aimed to investigate the effects and durability of 8-week Dynamic Neuromuscular Stabilization (DNS) exercises on pain, functional disability, and quality of life in individuals aged 30 to 50 years with non-specific chronic low back pain (NSCLBP).

METHODS

This research employed a pre- and post-test design with a follow-up period, in which 29 participants (16 in the control group and 13 in the exercise group) remained until the end of the study. Pain intensity, functional disability, and quality of life were assessed using the visual analog scale (VAS), the Oswestry Disability Index, and the SF-36 questionnaire, respectively, before intervention, immediately after, and two months post-intervention. The control group continued their routine daily activities, while the exercise group performed DNS exercises three times a week for 8 weeks. The data was analyzed using a mixed-design ANOVA (P ≤ 0.05).

RESULTS

The results showed improvements in pain (F (2,24) = 5.31, P = 0.01, η2 = 0.31), functional disability (F (2,24) = 4.17, P = 0.03, η2 = 0.26), and quality of life (F (2,24) = 4.70, P = 0.02, η2 = 0.28) in the exercise group at the Post-test compared to the Pre-test. However, the durability of the exercise effects at the follow-up assessment was not sustainable compared to the Post-test and Pre-test (P > 0.05).

CONCLUSION

An 8-week period of DNS exercises can improve pain, functional disability, and quality of life in individuals with NSCLBP. However, a 2-month period of detraining can reduce the positive outcomes of these exercises.

Investigating the effects of 25-hydroxyvitamin D3 on clinical outcomes in multiple sclerosis patients: A randomized, double-blind clinical trial- a pilot study

BACKGROUND

The primary objective of this clinical trial was to assess whether administrating oral calcifediol (25(OH)D3) could enhance the clinical outcomes of patients diagnosed with multiple sclerosis.

METHODS

This clinical trial was designed as a randomized, double-blind, two-arm study, with 25 participants receiving daily 50 μg of calcifediol and 25 people receiving daily 50 μg of cholecalciferol. The primary outcomes were serum levels of 25(OH)D3, number of relapses, changes in Kurtzke Expanded Disability Status Scale (EDSS), the 25-foot walk, and cognitive function.

RESULTS

At the end of the trial, delta serum concentrations of 25(OH)D3 were 85.32±40.94 ng/ml in the calcifediol group compared to 13.72±11.56 ng/ml in the cholecalciferol group; 84 % of the calcifediol group and none of the cholecalciferol group had circulating 25(OH)D3 concentrations exceeding 70 ng/ml. While both groups showed an overall trend towards improved cognitive function at the end of the study, the calcifediol group exhibited greater improvements in most cognitive tests. However, the trial had no significant beneficial effects on MS relapse, EDSS score, quality of life, or fatigue in either group, the calcifediol or cholecalciferol.

CONCLUSIONS

The trial shows that calcifediol is more effective in rapidly increasing 25(OH)D3 levels in MS patients compared to cholecalciferol when administrated at a similar dosage.

Valuing the SF-6Dv2 in the capital of Iran using a discrete choice experiment with duration

BACKGROUND

The second version of the Short-Form 6-Dimension (SF-6Dv2) classification system has recently been developed. The objective of this study was to develop a value set for SF-6Dv2 based on the societal preferences of a general population in the capital of Iran.

METHODS

A representative sample of the capital of Iran (n = 3061) was recruited using a stratified multistage quota sampling technique. Face-to-face interviews were conducted using binary choice sets from the international valuation protocol of the discrete choice experiment with duration. The conditional logit was used to estimate the final value set, and a latent class model was employed to assess heterogeneity of preferences.

RESULTS

Coefficients generated from the models were logically consistent and significant. The best model was the one that included an additional interaction term for cases where one or more dimensions reached their most severe levels. It provides a value set with logical consistent coefficients and the lowest percentage of worse than death health states. Predicted values for the SF-6Dv2 were within the range of - 0.796-1. Pain dimension had the largest impact on utility decrement, whereas vitality had the least impact. The presence of preference heterogeneity was evident, and the Bayesian Information Criterion indicated the optimal fit for a latent class model with two classes.

CONCLUSION

This study provided the SF-6Dv2 value set for application in the context of Iran. This value set will facilitate the use of the SF-6Dv2 instrument in health economic evaluations and clinical settings.

The effectiveness of multidisciplinary interventions based on health belief model on musculoskeletal pain in the elderly living in nursing homes: a study protocol for a randomized controlled trial

BACKGROUND

Due to the burden of musculoskeletal diseases in the elderly and the multifactorial nature of such conditions, controlling the pain caused by these disorders requires multidisciplinary approach. This approach requires the participation of the elderly in applying effective prevention measures. This study aims to design a multidisciplinary educational intervention based on health belief model (HBM) for elderly residents of nursing homes.

METHODS

This is a parallel randomized clinical trial among elderly people aged 60 years and over living in a nursing home who suffer from musculoskeletal pain. Eligible participants will be divided into two groups including the intervention group who will receive a multidisciplinary intervention (vitamin D consumption, psycho-social stress management, and physiotherapy) and the control group who will receive usual care. Data collection instruments will include demographic data, the Depression, Anxiety, and Stress Scale (DASS), the visual analogue scale (VAS), and a self-designed questionnaire containing the HBM constructs. The interventions will be carried out by the educational team (general practitioner, psychologist, physiotherapist, and health education specialist). Interventions include changing the wrong beliefs of the elderly, taking 800 units of vitamin D daily, daily walking exercise by the elderly for at least 30 min and maintaining proper body posture during daily activities, muscle relaxation, relaxation techniques, regular exercise, examining their diet and eliminating stimulants (such as smoking and coffee), regular visits with friends and family, and deep breathing techniques. All questionnaires will be completed by the elderly before, after, 3, and 6 months after the intervention.

DISCUSSION

The present study will evaluate the effect of an educational intervention based on a multifaceted pain control approach for elderly people who reside in nursing homes in order to reduce musculoskeletal pain in the elderly living in nursing homes. One of the features of this study is its focus on improving the health of elderly residents in nursing homes. Given the increase in the elderly population worldwide, the findings from the current trial might benefit elderly populations.

Predictors of health-related quality of life after total knee arthroplasty: a case-control study

Total knee arthroplasty (TKA) improves patients' Health-related quality of life (HRQoL) compared to before surgery. However, based on our knowledge, the improvement in HRQoL after TKA, which depends on various factors, has yet to be investigated compared to healthy people. This study aimed to evaluate the HRQoL of patients compared to healthy people and the factors affecting the HRQoL after TKA. In this matched case-control study (1002 participants), HRQoL in 501 patients who underwent TKA between 2015 and 2022 at Shafa Yahyainan Hospital affiliated with Iran University of Medical Sciences were compared with 501 healthy controls. HRQoL was evaluated in two parts (before compared to 12 months after TKA and 12 months after TKA compared to the healthy population). The 36-item short-form health survey (SF-36) was used to evaluate HRQoL 12 months after surgery. The influencing factors on HRQoL were evaluated by multivariate logistic regression analysis. No significant difference was observed in the demographic characteristics of the participants in the two groups. The mean overall SF-36 score, 12 months after surgery, significantly improved compared to before surgery (64.21 ± 22.2 vs. 37.55 ± 15.13, p:0.001). The mean total score of SF-36 was statistically similar between the case and control groups (64.21 ± 22.2 VS 72.53 ± 25.3). The multivariate analysis showed that sex, BMI, number of comorbidities, postoperative compliance, and complications were significantly related to the decrease in patients' HRQoL (P < 0.001).TKA can improve the HRQoL except for two subscales of happiness/vitality and physical performance, similar to the healthy population. Female gender, obesity and overweight, comorbidity, bilateral TKA, non-adherence to postoperative physiotherapy, and complications were associated with decreased HRQoL.

Effect of inpatient rehabilitation on the quality of life and life satisfaction in spinal cord injury

OBJECTIVE

Assess the impact of inpatient rehabilitation on the quality of life and life satisfaction of individuals with spinal cord injury by considering the level of injury.

DESIGN

QuasiExperimental study.

SETTING

Rehabilitation Hospital.

PARTICIPANTS

A total of 71 Patients with Spinal cord injury were admitted for rehabilitation.

INTERVENTION

The quality of life and life satisfaction of patients were assessed both before and after 63 days of inpatient rehabilitation.

MAIN OUTCOME MEASUREMENTS

Functional independence measure score (FIM), the Short Form-36 (SF-36), and the Life Satisfaction Scale (LSS).

RESULT

The average age of the study population was 34 ± 14 years. At the end of 63 days, significant improvements were observed in FIM, mood, health, physical performance, role physical, role emotional, pain, and total score of LSS (Π - Value <0.05). The variation in FIM changes significantly improved the total LSS score in the thoracic and thoracolumbar subgroups, but not in the cervical group. In addition, the total score of SF36 was improved significantly just in the cervical subgroup (Π = 0.006). No significant correlations were found between SF-36 and LSS scores (before and after the intervention) in relation to marriage, education, and time.

CONCLUSION

In the context of spinal cord injury, inpatient rehabilitation can play a role in improving functional independence which, in turn, impacts certain aspects affecting life satisfaction and the quality of life. It is important to note that the extent of this correlation varies among patients with different injury levels. In some cases, even minor changes, such as those seen in quadriplegic patients, could have a significant impact on their quality of life.

Effect of dry needling on pain and central sensitization in women with chronic pelvic pain: A randomized parallel-group controlled clinical trial

Chronic pelvic pain (CPP) is a debilitating problem in women with clear evidence of myofascial dysfunction. It seems that Myofascial trigger points (MTrPs) contribute to the development of central sensitization (CS). This study aimed to investigate the effect of dry needling on pain and CS in women with CPP. Thirty-six women with CPP participated in this randomized controlled clinical trial and randomly assigned into three groups: dry needling group (DNG), placebo needling group (PNG) and control group (CG). The DNG received five sessions of DN using the "static needling", the PNG received non-penetrating method, and the CG did not receive any intervention. Assessment of outcomes including central sensitization inventory (CSI), short-form McGill pain questionnaire (SF-MPQ), electroencephalography (EEG), conditioned pain modulation (CPM), salivary cortisol concentration, 7-item general anxiety disorder scale (GAD-7), pain catastrophizing scale (PCS), and SF-36 questionnaire was performed pre-intervention, post-intervention, and three months post-intervention by a blind examiner. The result showed a significant group-by-time interaction for CSI, SF-MPQ, and PCS. There was a significant decrease in CSI score in post-intervention and three-months post-intervention compare to pre-intervention in the DNG and PNG. SF-MPQ-PPI score in DNG significantly decreased post-intervention. PCS-Total score decreased significantly post-intervention in DNG and PNG. No significant group-by-time interactions were observed for other variables. EEG results showed regional changes in the activity of frequency bands in both eye closed and eye open conditions. It seems that DN can affect central pain processing by removing the source of peripheral nociception.

Mixture of Rhodiola rosea and Nelumbo nucifera Extracts Ameliorates Sleep Quality of Adults with Sleep Disturbance

Chronic sleep disturbance affects daily functioning, leading to decreased concentration, fatigue, and higher healthcare costs. Traditional insomnia medications are often associated with adverse side effects. This study investigated the efficacy of a novel compound derived from Rhodiola rosea and Nelumbo nucifera extracts (named RNE) in improving sleep quality with fewer side effects. The study included individuals between the ages of 20 and 65 with subthreshold insomnia and evaluated the effects of RNE on sleep, fatigue, and quality of life. Participants took 750 mg of RNE daily at bed-time for two weeks. The study used the Insomnia Severity Index (ISI), the Pittsburgh Sleep Quality Index (PSQI), a sleep diary, the Fatigue Severity Scale (FSS), and the Short Form 36 Health Survey (SF-36) for assessments. Of the 20 participants, 13 completed the study and showed significant improvements in sleep quality. The results showed improvements in ISI and PSQI scores, a 57% reduction in wake-time after sleep onset, and improved sleep efficiency. Although FSS scores remained unchanged, significant improvements were seen in SF-36 physical and mental health scores. The results suggest that RNE is an effective, low-risk option for sleep disturbance, significantly improving sleep quality and overall wellbeing without significant side effects.

Grape seed extract supplementation in non-alcoholic fatty liver disease

Background: Despite rising non-alcoholic fatty liver disease (NAFLD) prevalence and its impact on liver health, there's a lack of studies on grape seed extract's (GSE) effect on oxidative stress and quality of life (QoL) in NAFLD patients. This study aims to fill this gap by the potential benefits of GSE in reducing oxidative stress and improving QoL. Methods: In this randomized clinical trial study, fifty patients with NAFLD were randomly assigned to receive either 2 tablets of GSE containing 250 mg of proanthocyanidins or placebo (25 participants in each group) for two months. QoL was evaluated using the SF-36 questionnaire, and oxidative stress variables (TAC, MDA, SOD, GPx, CAT, and IL-6) were measured at the beginning and end of the study. Results: Compared with the control group, the group supplemented with GSE experienced greater reductions in IL-6 and MDA (3.14±1.43 pg/ml vs. 2.80±0.31 pg/ml; 4.16±2.09 μM vs. 4.59±1.19 μM, p for all <0.05), as well as greater increases in TAC, SOD, and GPx levels (0.18±0.08 mM vs. -0.03±0.09 mM; 10.5±6.69 U/ml vs. 8.93±1.63 U/ml; 14.7±13.4 U/ml vs. 8.24±3.03 U/ml, p for all <0.05). Furthermore, the QoL questionnaire showed that physical limitations, general health, and total physical health were significantly improved in the GSE group compared with the placebo (17.0±42.0 vs. -12.0±37.5; 3.80±14.8 vs. -3.92±9.55; 5.08 5.26 vs. -7.01±13.7, p for all <0.05). Conclusions: GSE can be effective in improving oxidative stress and QoL in patients with NAFLD. More studies are needed to confirm the results of this study.

Association Between Preoperative Long-Term Poor Sleep Quality and Postoperative Delirium in Elderly Patients Undergoing Cardiac Surgery: A Multi-Center Observational Study

BACKGROUND

Delirium is a common complication in elderly patients after cardiac surgery, and sleep disorders have been suggested as a potential risk factor. However, few studies have explored the link between long-term preoperative poor sleep quality and postoperative delirium (POD) in this population. This study aimed to investigate the association between preoperative sleep quality and POD in elderly cardiac surgery patients.

METHODS

The study enrolled 194 patients aged 60 years or older who underwent cardiac surgery. The Pittsburgh Sleep Quality Index (PSQI) objectively assessed preoperative sleep quality, while the Confusion Assessment Method screened for POD. The measurable outcomes encompassed the identification of risk factors associated with POD, while the secondary outcomes focused on factors influencing levels of consciousness. The statistical analysis is logistic regression analysis.

RESULTS

Patients with POD had a higher prevalence of preoperative sleep disorders and higher PSQI scores than those without delirium (12.9 ± 5.1 vs 7.8 ± 3.4, P = .007). Logistic regression analysis demonstrated that the number of months with high PSQI scores and age were significantly associated with POD. The predictive ability of the number of months with high PSQI scores for POD was .762 (95% CI: .671-.854). Multivariate linear regression analysis revealed that preoperative sleep disorder was a significant predictor of exacerbation of POD (P < .05).

CONCLUSION

This study suggests that long-term poor preoperative sleep quality, as assessed by the PSQI, is associated with an increased risk of POD in elderly patients undergoing cardiac surgery.

The relationship between spiritual health and quality of life among COVID-19 patients with long-term complications in the post-coronavirus era

Objective

COVID-19 has varied manifestations and can cause complications that affect quality of life. Spiritual health may be a source of adaptation for these patients. This study investigated the relationship between spiritual health and quality of life among COVID-19 patients with long-term complications in the post-coronavirus era.

Participants/methods

This study enrolled 475 COVID-19 patients through convenience sampling from medical facilities located in the Central Province of Iran. Data collection occurred between November 2022 and July 2023. A demographic checklist was utilized to ascertain the presence of potential COVID-19 complications. Patients exhibiting at least one long-term complication of COVID-19 were classified into the group with complications, while those without such complications were categorized into the group without complications. Subsequently, spiritual health and quality of life were assessed utilizing Paloutzian and Ellison's Spiritual Well-Being Scale and the 36-item Short Form Health Survey (SF-36), respectively. Statistical analysis was conducted using SPSS-20.

Results

The mean scores of spiritual well-being and quality of life for participants without COVID-19 complications were 70.87 ± 22.44 and 61.30 ± 18.33, respectively. In contrast, the mean spiritual health scores and quality of life for participants with COVID-19 complications were 41.20 ± 12.49 and 33.66 ± 1.46, respectively. Moreover, spiritual well-being was positively associated with quality of life among COVID-19 patients (p < 0.05).

Conclusion

This study indicates that COVID-19 complications can impair patients' spiritual health and quality of life, leaving them vulnerable and distressed. However, patients with higher spiritual health can cope better and enjoy a higher quality of life, despite challenges. Therefore, this study highlights the importance of addressing the spiritual needs of patients with COVID-19 complications and providing them with adequate support and care.

The effect of a suspension training on physical fitness, lower extremity biomechanical factors, and occupational health in Navy personnel: a randomized controlled trial

Optimal physical fitness is essential for military personnel to effectively meet their rigorous physical demands. This study aimed to investigate the effectiveness of a suspension training program on physical fitness, biomechanical risk factors for lower extremity injury, mental health, and work-related factors in Navy personnel. A total of 50 young men participated in a randomized controlled trial. The participants were randomly assigned to two groups (n = 25): the intervention group and the control group. The intervention group performed an eight-week suspension training session three times per week, while the control group maintained their daily duties. The primary outcome was physical performance. The secondary outcomes were determined biomechanical risk factors for lower extremity injuries, mental health, and work-related factors. The data were analyzed using the analysis of covariance (ANCOVA). Compared with the control group, the intervention group showed significant improvements in physical performance, biomechanical risk for lower extremity injuries, and work-related factors from baseline to follow-up (p ≤ 0.05). However, there was no improvement in mental health. Based on these findings, suspension training positively impacted physical fitness, reduced injury risk, and enhanced the work-related factors of Navy personnel. This study provides new insights for various related experts and military coaches because it is an easy-to-use and feasible method with minimal facilities.

Cross-Cultural Adaptation and Validation of the Persian Version of the M. D. Anderson Dysphagia Inventory

Introduction  Dysphagia is a common issue in patients with head and neck cancer (HNC) and is known to negatively impact their quality of life. To evaluate the impact of dysphagia on the quality of life of HNC patients, the M. D. Anderson Dysphagia Inventory (MDADI) questionnaire was developed. Objective  The present study aimed to culturally adapt and validate the MDADI for Persian-speaking individuals. The MDADI is a self-administered questionnaire designed to assess the impact of dysphagia on the quality of life of HNC patients. Methods  The original MDADI questionnaire was translated into Persian using the forward-backward method, following the guidelines of the World Health Organization (WHO) for cultural adaptation. The content validity of the Persian version, MDADI-P, was assessed by 10 speech-language pathologists using the content validity index (CVI). Seventy-five HNC patients completed the MDADI-P to evaluate its convergent validity, which was determined by comparing the results with the Short-Form 36 (SF-36) questionnaire. Internal consistency and test-retest reliability were assessed using Cronbach α coefficient and intraclass correlation (ICC), respectively. Results  The scale content validity index (S-CVI) for the MDADI-P was 0.90, indicating good content validity. The MDADI-P demonstrated satisfactory internal consistency (Cronbach α coefficient = 0.728) and test-retest reliability (ICC = 0.91). The total MDADI-P score exhibited a significant correlation with the physical and mental components of the SF-36 (0.456 and 0.349, respectively, p  < 0.05). Conclusion  The findings of the present study confirm the suitability of the MDADI-P in terms of content validity, construct validity, internal consistency, and test-retest reliability.

Translation and psychometric evaluation of the Persian version of the nurses' quality of life scale: a validation study in Iran

BACKGROUND

The quality of life for nurses can be significantly impacted by various occupational factors that Influence their working conditions and professional performance. The current study aimed to translate and validate the Persian version of the Nurses' Quality of Life Scale.

MATERIAL AND METHOD

In this cross-sectional research, the Nurses' Quality of Life Scale (NQOLS) was utilized to assess the quality of life among 500 employed nurses in hospitals in the cities of Gonabad and Sabzevar. The translation process of the NQOLS followed the model proposed by Wild et al. The content validity of the Persian version of the scale was evaluated using the Content Validity Index (CVI) and Content Validity Ratio (CVR). Structural validity was assessed using exploratory and confirmatory factor analyses. Internal consistency reliability was assessed using Cronbach's alpha, while test-retest reliability was determined using the Intraclass Correlation Coefficient (ICC). Data analysis was conducted using SPSS version 26 and LISREL version 8.8 software.

RESULTS

The exploratory factor analysis of the Persian version of NQOLS revealed six factors that accounted for 62.15% of the total variance. The structural validity of the extracted factors was confirmed through confirmatory factor analysis. The Cronbach's alpha coefficient and ICC for the entire questionnaire were 0.91 and 0.95, respectively.

CONCLUSION

The findings of the present study suggest that the Persian version of the NQOLS exhibits sufficient validity and reliability. Therefore, it can be used as an effective tool for measuring and examining the quality of life among nurses in Iran.

Effects of telerehabilitation-based respiratory and corrective exercises among the elderly with thoracic hyper-kyphosis: a clinical trial

BACKGROUND

Aging is associated with changes in the musculoskeletal system, including increased susceptibility to spine malalignments. Utilizing corrective exercises with a therapeutic emphasis can be beneficial in the elderly with thoracic spine hyperkyphosis.

OBJECTIVE

This study aimed to investigate the effects of six weeks of telerehabilitation-based respiratory and corrective exercises on quality of life, disability, thoracic kyphosis, craniovertebral angle, shoulder angle, cranial angle, and chest expansion in the elderly with thoracic spine hyperkyphosis.

METHODS

In this clinical trial, a total of 40 participants aged 60 and above with thoracic hyperkyphosis were randomly divided into the control (N = 20) and experimental (N = 20) groups. The experimental group performed the corrective exercises for six weeks (3 sessions per week). The control group performed general stretching exercises during the same time period. We measured the outcomes of quality of life, disability, thoracic kyphosis, craniovertebral angle, shoulder angle, cranial angle, and lung expansion before and after the intervention. Analysis of covariance (ANCOVA) was employed to analyze the data. A P-value ≤ 0.05 was considered statistically significant.

RESULTS

Quality of life (P < 0.001, Effect Size (ES): 0.44), chest expansion (P < 0.001, ES: 0.56), thoracic kyphosis angle (P < 0.001, ES: 0.31), craniovertebral (P < 0.001, ES: 0.33), cranial (P < 0.001, ES: 0.38), and shoulder (P = 0.005, ES: 0.20) angles were significantly improved in the experimental group as compared with controls. However, no statistically significant difference was observed between the two groups in terms of physical ability (P = 0.251, ES: 0.04).

CONCLUSION

It is therefore recommended that online corrective exercises be used in the rehabilitation protocol to improve the quality of life, posture, chest expansion, and disability in the elderly with thoracic kyphosis.

Adherence to the nordic diet is associated with anxiety, stress, and depression in recovered COVID-19 patients, a case-control study

BACKGROUND

Follow-up of COVID-19 recovered patients to discover important adverse effects on other organs is required. The psychological health of COVID-19 patients may be affected after recovery.

AIM

We aimed to evaluate the association between adherence to the Nordic diet (ND) and psychological symptoms caused by COVID-19 after recovery.

METHOD

Dietary data on 246 qualified adults (123 cases and 123 controls). The dietary intake in this case-control study was calculated by a reliable and valid food frequency questionnaire (FFQ). Depression Anxiety Stress Scale (DASS), Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and Short-Form Health Survey (SF-36) were used to analyze participant's anxiety, stress, depression, sleep quality, insomnia, and quality of life of participants.

RESULTS

There was a significant inverse relationship between total anxiety, stress, and depression scores and the intake of whole grains (P < 0.05). Furthermore, there was a significant inverse association between depression and fruit intake (P < 0.05). A significant negative correlation was found between insomnia and sleep quality and the intake of root vegetables (P < 0.05). In the multinomial-regression model, a significant association between the Nordic diet and anxiety, stress, and depression was found only in the case group (OR = 0.719, 95% CI 0.563-0.918, p-value = 0.008; OR = 0.755, 95% CI 0.609-0.934, P-value = 0.010, and, OR = 0.759, 95% CI 0.602-0.956, P-value = 0.019 respectively).

CONCLUSION

Adherence to the Nordic diet might reduce anxiety, stress, and depression in recovered COVID-19 patients.

Long-Term Clinical and Imaging Findings in Patients with Lower Extremity Varicose Veins Treated with Endovenous Laser Treatment: A Follow-Up Study of up to 12 Years

Introduction

This study investigates the long-term effectiveness and safety of endovenous laser treatment (EVLT) for chronic venous insufficiency (CVI), a condition commonly caused by dysfunctional valves in the venous circulation system.

Materials and Methods

In this retrospective cohort study, patients underwent EVLT and were followed up for successive short intervals and one last time after a median duration of 9-year postprocedural. Pre- and postprocedure duplex ultrasound was used to assess changes in the great saphenous vein (GSV) diameter, reflux, and saphenofemoral junction incompetence. Quality of life was evaluated using the SF-36 and Aberdeen Varicose Vein Questionnaire (AVVQ).

Results

Sixty-eight patients with a mean age of 52.4 ± 12.4 years were enrolled in the study. The mean follow-up time was 8.9 ± 2.1 years, ranging from 5 to 12 years. The mean GSV diameter significantly decreased in all patients (whole group) across proximal (from 5.8 ± 2.3 mm to 4.2 ± 2.1 mm), middle (from 4.7 ± 1.6 mm to 2.8 ± 2.2 mm), and distal (from 4.5 ± 2.3 mm to 2.2 ± 2.2 mm) segments, with P < 0.001. A disease recurrence rate of 33.8% was noted, predominantly in male patients and those with larger middle GSV diameters (OR = 5.2 (95%CI = 1.3-20.4) and OR = 1.5 (95%CI = 1-2.1), respectively). The average follow-up time for patients without recurrence was 8.8 ± 2.1 years. Almost half of the patients without recurrence were followed up for 10 years or more (49%).

Conclusion

The efficacy of EVLT in managing varicose veins is demonstrated by its relatively low recurrence rate over a 10-year follow-up period, highlighting EVLT as a viable long-term treatment strategy.

Validity and reliability of the Persian version of the STarT musculoskeletal tool

BACKGROUND

The Subgrouping for Targeted Treatment (STarT) musculoskeletal (MSK) tool stratifies patients with MSK disorders (MSDs) into prognostic categories based on poor outcomes.

PURPOSE

This study aimed at investigating the validity and reliability of the Persian STarT MSK tool in people suffering from painful MSDs in Iran.

METHODS

A total of 593 subjects with painful MSDs including neck, shoulder, low back, knee, and multisite pain received and completed the STarT MSK tool, visual analog scale (VAS), EuroQol five-dimensions three-levels questionnaire (EQ-5D-3 L), short form-36 health survey questionnaire (SF-36), and Örebro musculoskeletal pain screening questionnaire (ÖMPSQ) in the first visit. To examine test-retest reliability, 234 patients completed the STarT MSK tool 2 days after the initial visit.

RESULTS

In this study, 139 (23.5%), 266 (44.9%), and 188 (31.7%) participants were classified as low-, medium-, and high-risk groupings for poor outcomes, respectively. Spearman's correlation coefficient showed a strong relationship among Persian STarT MSK tool and EQ-5D-3 L (-0.78), SF-36 (-0.76), and OMPSQ (0.70). The results of known-group validity indicated that this tool could distinguish among the participants in different risk subgroups based on the scores of the ÖMPSQ, VAS, SF36, and EQ-5D-5 L (p < .001). No ceiling and floor effects were observed. Cronbach's alpha and intra-class correlation coefficient (ICC2,1) were acceptable (0.71) and excellent (0.98), respectively.

CONCLUSION

The Persian version of STarT MSK tool has shown to be a valid and reliable instrument to stratify people with painful MSDs into low-, medium-, and high-risk subgroups based on persistent pain disability.

Comparing Epley Maneuver, Betahistine, and Dimenhydrinate in the Treatment of Benign Paroxysmal Positional Vertigo: A Prospective Study

Although the Epley maneuver is considered the primary treatment in BPPV, anti-vertigo medications are effective in residual symptoms. This study was designed to compare betahistine and dimenhydrinate plus the Epley maneuver and the Epley maneuver alone. This prospective cohort study was performed in Mashhad, Iran, from 2013 to 2015. 90 adult patients diagnosed with BPPV in hospitals and ENT clinics were selected through convenience sampling. Patients received betahistine 8 mg TDS or dimenhydrinate 50 mg once daily plus Epley or the Epley alone for four weeks. SF-36 and the DHI were used before and after the treatment. 49 were females (54.4%). The mean (SD) age was 47.9 (8.7) years. There was no significant difference between the groups in age (P = 0.753) and gender (P = 0.050).There were significant differences in all areas of SF-36 except for social activities in the dimenhydrinate group. There was a marginally significant difference between the betahistine and dimenhydrinate groups in role limitation due to physical health problems (P = 0.046). There were significant differences between the females and males in emotional well-being before and after treatment in the dimenhydrinate group (P = 0.014) and in terms of role limitation due to physical health problems in the Epley maneuver group (P = 0.022). Older patients in the betahistine group had better social activities after treatment (P = 0.048). In severe forms of BPPV, betahistine or dimenhydrinate might effectively reduce the symptoms.

Comparing depression, anxiety, and quality of life in individuals with cardiac and non-cardiac chest pain

Background

Psychological factors are often overlooked as potential contributors to cardiovascular disease. This study aimed to investigate the relationship between depression, anxiety, and quality of life with chest pain origin.

Method

This cross-sectional study was performed from 2019 to 2020 and included participants from multiple medical centers across Shahrekord, Iran. Participants were recruited through advertisements in medical centers. Participants were divided into three groups: healthy control (n = 67), chest pain with cardiac origin (CCP) (n = 70), and chest pain with non-cardiac origin (NCCP) (n = 73). Data were collected using the Beck's Anxiety scale, Beck's Depression scale, and Short-Form Health Survey questionnaires. The chi-square, exact test, t-test, Kruskal-Wallis, and logistic regression models were used for statistical analysis. All analysis was performed using SPSS 26.

Results

The mean scores of depression and anxiety in the NCCP group (depression = 17.03 ± 11.93, anxiety = 17.18 ± 11.37) were significantly higher than those in the CCP (depression = 9.73 ± 5.76, anxiety = 8.77 ± 5.96) and healthy (depression = 7.00 ± 7.61, anxiety = 6.18 ± 7.63) groups (p < 0.05). The mean score of quality of life in the NCCP group (54.87 ± 12.66) was significantly lower than that in the CCP (76.31 ± 12.49) and healthy (80.94 ± 15.78) groups (p < 0.05). Patients with NCCP had higher odds of having depression (adjusted OR = 4.39, 95% CI: 1.25, 15.35) and lower odds for having mental quality of life scores than the CCP and health groups, respectively (adjusted OR = 0.90, 95% CI: 0.87, 0.94).

Conclusion

Our findings suggest that collaboration between psychiatrists and other specialists may be necessary to improve patients' health conditions and quality of life.

A population study on factors associated with unintentional falls among Iranian older adults

INTRODUCTION

Falls among older adults are a significant cause of disability, injury, and death worldwide. The high incidence of falls in older adults, combined with the increased susceptibility to injury of the older adult population, leads to severe global health issues. Further studies are needed to comprehensively evaluate the typical personal and environmental risk factors of falls in the Iranian elderly population. Future preventive strategies and intervention programs will be based on these findings. The study determined the risk factors associated with unintentional falls among a representative sample of older adults living in Tehran, the capital city of Iran.

METHODS

The study design was cross-sectional. The target population was men/women aged 65 years and over from the general population living in 22 different districts of Tehran who were selected by stratified random sampling. The researchers gathered the data using validated questionnaires and observations. The informed consent was obtained from all participants before starting the interview. Multivariate logistic regression analysis examined the association between falls occurring during the past 12 months with demographics/ socioeconomics and fall-related predictor factors.

RESULTS

The risk of falls was higher in women (47.0%) and those aged ≥ 75 years (44.1%). Older adults who were married had their fall risk reduced by 36.4% compared with other types of marital status. Older adults who were illiterate (48.1%), housewives (47.0%), and always had concerns about living expenses (53.9%) tended significantly to have a higher risk of falls. Moreover, participants who live with their family were less likely to fall than those who live alone (36.5% vs. 40.4%). Persons with safe homes were less likely to experience falls than persons with unsafe homes (30.9% vs. 41.4%). The logistic regression analysis showed that the female gender, being worried about living expenses, home safety, functional behavior, and function factors, were independently associated with the risk of falls during the past 12 months.

CONCLUSIONS

Our findings revealed that a wide range of intrinsic and extrinsic risk factors contributed to injurious falls; based on the literature, some are preventable. The present data may be helpful as a starting point and guide future efforts for health providers and policymakers to allocate additional resources and develop proper falls prevention or intervention programs at the community level.

The effects of curcumin-piperine supplementation on inflammatory, oxidative stress and metabolic indices in patients with ischemic stroke in the rehabilitation phase: a randomized controlled trial

BACKGROUND

Stroke is a leading cause of death worldwide, which is associated with a heavy economic and social burden. The purpose of this study was to investigate the effects of supplementation with curcumin-piperine combination in patients with ischemic stroke in the rehabilitation stage.

METHODS

In this randomized controlled trial, 66 patients with stroke were randomized into two groups receiving curcumin-piperine tablets (500 mg curcumin + 5 mg piperine) and matched placebo tablets for 12 weeks. High-sensitivity C-reactive protein (hs-CRP), carotid intima-media thickness (CIMT), thrombosis, total antioxidant capacity (TAC), lipid profile, anthropometric indices, blood pressure, and quality of life were assessed before and after the intervention. Statistical data analysis was done using SPSS22 software.

RESULTS

A total of 56 patients with a mean age of 59.80 ± 4.25 years completed the trial. Based on ANCOVA test, adjusted for baseline values, curcumin-piperine supplementation for 12 weeks resulted in significant reductions in serum levels of hs-CRP (p = 0.026), total cholesterol (TC) (p = 0.009), triglycerides (TG) (p = 0.001), CIMT (p = 0.002), weight (P = 0.001), waist circumference (p = 0.024), and systolic and diastolic blood pressure (p < 0.001), and a significant increase in TAC (p < 0.001) in comparison to the placebo. Pain score significantly increased in both groups; however, its increase was significantly higher in the placebo group compared with the intervention group (p = 0.007). No significant changes were observed between the two groups in terms of serum fibrinogen, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and quality of life indices.

CONCLUSION

Curcumin-piperine supplementation had beneficial effects on CIMT, serum hs-CRP, TC, TG, TAC, and systolic and diastolic blood pressure in patients with ischemic stroke in the rehabilitation stage.

Effect of multidimensional physiotherapy on non-specific chronic low back pain: a randomized controlled trial

BACKGROUND

Many people with non-specific chronic low back pain (NSCLBP) do not recover with current conventional management. Systematic reviews show multidimensional treatment improves pain better than usual active interventions. It is unclear whether multidimensional physiotherapy improves pain better than usual physiotherapy. This study determines the effectiveness of this treatment to reduce pain and disability and improve quality of life, pain cognitions, and electroencephalographic pattern in individuals with NSCLBP.

METHODS

70 eligible participants aged 18 to 50 years with NSCLBP were randomized into either the experimental group (multidimensional physiotherapy) or the active control group (usual physiotherapy). Pain intensity was measured as the primary outcome. Disability, quality of life, pain Catastrophizing, kinesiophobia, fear Avoidance Beliefs, active lumbar range of motion, and brain function were measured as secondary outcomes. The outcomes were measured at pre-treatment, post-treatment, 10, and 22 weeks. Data were analyzed using intention-to-treat approaches.

RESULTS

There were 17 men and 18 women in the experimental group (mean [SD] age, 34.57 [6.98] years) and 18 men and 17 women in the active control group (mean [SD] age, 35.94 [7.51] years). Multidimensional physiotherapy was not more effective than usual physiotherapy at reducing pain intensity at the end of treatment. At the 10 weeks and 22 weeks follow-up, there were statistically significant differences between multidimensional physiotherapy and usual physiotherapy (mean difference at 10 weeks, -1.54; 95% CI, -2.59 to -0.49 and mean difference at 22 weeks, -2.20; 95% CI, - 3.25 to - 1.15). The standardized mean difference and their 95% confidence intervals (Cohen's d) revealed a large effect of pain at 22 weeks: (Cohen's d, -0.89; 95% CI (-1.38 to-0.39)). There were no statistically significant differences in secondary outcomes.

CONCLUSIONS

In this randomized controlled trial, multidimensional physiotherapy resulted in statistically and clinically significant improvements in pain compared to usual physiotherapy in individuals with NSCLBP at 10 and 22 weeks.

The association of hematological inflammatory markers and psychological function in COVID-19 patients: A cross-sectional study

Mental health disorders are linked to systemic inflammation. Due to high inflammation and mental health disorders in COVID-19 patients, we aimed to investigate the relationship between blood inflammatory markers such as red cell distribution width to platelet ratio (RPR), platelet-lymphocyte ratio (PLR), neutrophil/lymphocyte ratio (NLR), red cell distribution width (RDW), white blood cell (WBC), and psychological function in COVID-19 patients. In the current cross-sectional study, neuro-psychological function, and a complete blood count (CBC) were measured on 120 COVID-19 patients aged >30 years from the Imam Reza Hospital in Mashhad, Iran. Our results showed that anxiety related to MCHC (mean ± SD: 32.71 ± 1.68, p < 0.05), WBC (mean ± SD: 12.23 ± 5.43, p < 0.05), and PLR (median (IQR): 28.72 (15.88-41.31), p < 0.05) significantly. In the stress subgroup, only RPR was associated with stress (p < 0.05). Linear regression between hematological parameters and psychological score indicated that RDW and PLR had a significantly positive association with depression (β = 0.086; p = 0.045 and β = 1.326; p = 0.016, respectively) and anxiety scores (β = 0.100; p = 0.038 and β = 1.356; p = 0.010, respectively). Moreover, a positive correlation was found between PLR and stress (β = 1.102; p = 0.012). This study showed a positive association between depression/anxiety/stress symptoms and levels of hematological inflammatory markers including PLR and RDW. The findings of this study provide novel insights into mental health and physiological markers, underscoring the potential influence of inflammation on mood disorders. Our findings offer exciting prospects for future research and may lead to innovative approaches in the management and treatment of depression, anxiety, and stress.

Evaluation of quality of life and associated factors in patients with intertrochanteric femoral fracture

BACKGROUND

Intertrochanteric fracture is a common injury among the elderly, causing fundamental lifestyle derangements, influencing the patients' social and psychological functioning. We aimed to study the quality of life (QoL) and its different parameters in patients with this type of injury.

MATERIALS AND METHODS

In this cross-sectional study, all patients hospitalized with intertrochanteric fracture aged above 50 from 2020 to 2022 at the Shahid Beheshti Hospital in Babol, Iran, were included. Patients were primarily managed surgically and, in exceptional cases non-surgically, were followed up for at least 12 months after receiving treatment. During the follow-up period, patients were dialled and completed a questionnaire to assess the patient's QoL by the 36-item Short Form Health Survey (SF-36). QoL parameters were analyzed based on patients' sex, age, type of treatment, and height of fall causing fracture.

RESULT

A total number of 200 patients, including 101 (50.5%) males and 99 (49.5%) females, with a mean age of 74.76±11.36 years (range: 50-99), were included. Regarding the received treatment, 192 (96.0%) patients underwent surgery, and 8 (4.0%) underwent non-surgical treatment. In the study of SF-36 scores, the mean score of male patients was 42.31±14.58, and females scored 37.83±15.35, and the difference was statistically significant (P = 0.04). The mean score of QoL and its subscales among the 50-75 group patients was significantly higher than the 76-99 group (P<0.001). The average score of QoL was considerably higher in patients who had surgery (40.75±14.57) compared to those who had non-surgical treatment (24.30±19.85) (P = 0.01). Patients having a fall from a higher height had higher QoL after treatment.

CONCLUSION

This study revealed that patients with an intertrochanteric femoral fracture had poor QoL in all aspects. The overall QoL was significantly higher among male patients, younger patients, those who underwent surgical treatment, and the falls from higher heights. These findings highlight the necessity of long-term follow-up and support in patients with intertrochanteric fractures.

Development and psychometric properties of Iranian Women's Quality of Life Instrument (IWQOLI): mixed exploratory study

BACKGROUND

To determine the health needs and promote women's health, their quality of life should be investigated. For this purpose, a valid tool is needed, that has credible validity and reliability, and its concepts are clearly defined and culturally appropriate. This study aimed to develop and assess the psychometric properties of "Iranian Women's Quality of Life Instrument (IWQOLI)".

METHODS

The items of "IWQOLI" were generated from themes extracted (150 items) from a content analysis approach with the participation of 40 women. Face validity of the questionnaire with the participation of 10 women and content validity by 10 experts was approved. To determine the domains of the questionnaire, exploratory factor analysis (principal component extraction method) was performed. Internal consistency and test-retest reliability methods with 14-day intervals (30 women) were used to assess the reliability of WQOLI.

RESULTS

After performing the face and content validity, 32 items were deleted. S-CVI/Ave was obtained for the instrument (0.93). The factor structure of the inventory was identified by undertaking a principal component analysis in a sample of 590 women. Five factors were extracted with a total variance account of 56.24% and 28 items dropped at this point. The IWQOLI score was significantly correlated with the SF-36 (r = 0.717, p < 0.001). Reliability was demonstrated with Cronbach's alpha coefficient of 0.919 for the entire scale (90-item). Consistency of the instrument was established with test-retest reliability with an interval of 2 weeks (intra-cluster correlation = 0.889, P < 0.001).

CONCLUSIONS

The Iranian women's Quality of life Instrument "IWQOLI", consisting of 90 items representing 5 domains (sense of peace in life, sense of security, health responsibility, pleasant communication, received comprehensive support), demonstrated excellent psychometric properties, so it may be used for measuring women's QOL in practical research.

A comparative study on the effects of Mitchell and Benson relaxation techniques on quality of life of the old people in nursing homes: a quasi- experimental study

BACKGROUND

There is slight evidence on the effectiveness of relaxation techniques to improve quality of life of the old people, and no comparative studies have particularly investigated this population. Hence, the present study was conducted to examine the effect of Mitchell relaxation versus Benson relaxation technique to improve quality of life of the old people.

METHODS

In the present quasi-experimental study, 96 eligible old people in a nursing home were selected by available sampling method. Afterwards, they were assigned to three groups: Mitchell's Relaxation Technique, Benson Relaxation Technique, and control (each of 32 participants) using the random block sampling method. The intervention groups received relaxation for 8 weeks and 3 sessions of 20 min each week. However, the control group did not receive any relaxation. Data was gathered by questionnaires (SF-36) and (CASP-19) before (week 0) and after the intervention (week 8) and were analyzed using the SPSS software version 26.

RESULTS

The results indicated that both Benson and Mitchell relaxation had improved the quality of life (SF-36) and (CASP-19) and their sub-scales in the participants compare to the control group (P < 0.001). Accordingly, the median (quartile 25, 75) of the specific quality of life of the participants before the intervention was 21 (18.25, 25.75) in the Benson group, 20.5 (16, 24) in the Michel group, and 21 (16.25, 24) in the control group. However, after the intervention they reached 35(26.25, 38.75), 34.5(26.75, 42.25), and 17 (14, 21) respectively. There was no statistically significant difference between the Benson and Michel relaxation groups.

CONCLUSIONS

Based on the results, Benson and Mitchell relaxation techniques improve the quality of life of the old people. If the results be confirmed in other studies, the education of each of them, especially for the old people living in nursing homes and their caregivers, is suggested as routine care.

Using an adaptive network-based fuzzy inference system for prediction of successful aging: a comparison with common machine learning algorithms

INTRODUCTION

The global society is currently facing a rise in the elderly population. The concept of successful aging (SA) appeared in the gerontological literature to overcome the challenges and problems of population aging. SA is a subjective and multidimensional concept with many ambiguities regarding its meaning or measuring. This study aimed to propose an intelligent predictive model to predict SA.

METHODS

In this retrospective study, the data of 784 elderly people were used to develop and validate machine learning (ML) methods. Data pre-processing was first performed. First, an adaptive neuro-fuzzy inference system (ANFIS) was proposed to predict SA. Then, the predictive performance of the proposed model was compared with three ML algorithms, including multilayer perceptron (MLP) neural network, support vector machine (SVM), and random forest (RF) based on accuracy, sensitivity, precision, and F-score metrics.

RESULTS

The findings indicated that the ANFIS model with gauss2mf built-in membership function (MF) outperformed the other models with accuracy, sensitivity, precision, and F-score of 91.57%, 95.18%, 92.31%, and 92.94%, respectively.

CONCLUSIONS

The predictive performance of ANFIS is more efficient than the other ML models in SA prediction. The development of a decision support system (DSS) using our prediction model can provide healthcare administrators and policymakers with a reliable and responsive tool to improve elderly outcomes.

The Therapeutic Efficacy of Freeze-Dried Human Amniotic Membrane Allograft Gel for Diabetic Foot Ulcers: A Phase-1 Clinical Trial

Diabetic foot ulcers (DFUs) are classified as hard-to-heal wounds, which occur in approximately 15% of diabetic patients. Several interventions have shown efficacy in reducing the risk of amputation among patients with DFU, including timely diagnosis and management of infection and ischemia, debridement of necrotic tissues, reducing mechanical pressure on ulcers, and patient education. One major challenge in the management of DFUs is optimizing wound care to improve healing outcomes. Recently, interdisciplinary approaches proposed a new generation of wound dressing which increased efficacy and significantly decreased the healing time. The current study assessed the healing characteristics of chronic DFUs treated with lyophilized amniotic membrane gel (LAMG) in combination with standard care, versus a placebo hydrogel with standard care. In total, 18 patients (8 male, 10 female) were randomly assigned to the control group, which received standard care and a gelatin scaffold (placebo), or the intervention group, which received standard care along with LAMG. We evaluated the reduction in wound size and assessed the patient's health-related quality of life over 9 weeks. In the LAMG group (n = 9) and the Placebo group (n = 9), the wounds were reduced in size by a mean of 73.4% ± 15.3% and 13.1% ± 10.1%, respectively (P = .008). Patients treated with LAMG demonstrated significant improvements in the scores related to physical function, physical limitation, physical pain, general health, social function, emotional problems, and energy levels compared to the control group. The findings of this study indicate that using the LAMG with standard care significantly enhances wound healing.

The effects of weight loss on health-related quality of life in obese women with PCOS and controls

BACKGROUND

Polycystic ovary syndrome (PCOS) is a complicated endocrine disorder with widespread symptoms that reduce women's quality of life. The adverse effect of associated obesity on this reduction is unclear, therefore the impact of weight loss on health-related quality of life (HRQOL) in obese women with PCOS is unknown. This study aimed to compare the impact of weight loss following a 24-week dietary intervention on HRQOL in obese women with and without PCOS.

METHODS

In a 24-week hypocaloric LGI (low glycemic index) diet intervention study, 286 women were recruited (140 PCOS, 146 controls) and 216 participants (PCOS = 105, non-PCOS = 111) completed the study. HRQOL was assessed using the SF-36 questionnaire (Short Form Health Survey). Physical activity was measured using the short form of the International Physical Activity Questionnaire (IPAQ). Anthropometric assessments, dietary intake, physical activity levels, and HRQOL scores, according to the Iranian version of SF-36, were compared at baseline and 24 weeks with intervention.

RESULTS

At the end of the intervention, there was no significant difference in the percentages of weight loss between the two groups (PCOS: 6.29 ± 3.32% vs. non-PCOS: 7 ± 3.62%, p = 0.1). At baseline, women with PCOS had lower mean scores in aspects of physical function (PF), general health perception (GH), role limitation due to emotional problem (RE), vitality (VT), mental health (MH), physical (PCS) and mental component summary scales (MCS), compared to non-PCOS (P < 0.01). At 24 weeks, the percentage of improvement in HRQOL in the non-PCOS group was higher compared to the PCOS group but this difference didn't reach statistical significance except for PCS. In both groups, greater weight loss was associated with further improvement in the physical aspects of HRQOL and vitality. In the non-PCOS group, with trivial exception, greater weight loss was associated with greater improvement in the mental aspects of HRQOL.

CONCLUSIONS

Both obese PCOS and non-PCOS women achieved nearly similar levels of improvement in HRQOL due to weight loss induced by a hypocaloric LGI diet.

The effect of cognitive behavioral therapy on stress and anxiety of mothers of girls with precocious puberty symptoms: a randomized controlled trial

INTRODUCTION

Precocious puberty in girls has been associated with an increased risk of stress and anxiety in their mothers. This study aimed to investigate the effect of cognitive behavioral therapy (CBT) on perceived stress and anxiety of mothers of girls with precocious puberty symptoms.

METHODS

This randomized controlled trial was conducted on 70 mothers of girls with precocious puberty symptoms in Tabriz-Iran, 2021. The participants were randomly assigned to CBT and control groups through blocked randomization. Group counseling was provided to the intervention group in eight sessions of 45-60 min weekly with 5 to 7 women. A booklet containing explanations about puberty was provided for the both groups. Data were collected using the questionnaires of socio-demographic characteristics, Spielberger State-Trait Anxiety Inventory (STAI), Perceived Stress Scale (PSS) and quality of life (SF-36). Independent t-test, ANCOVA, chi-square, and fisher's exact tests were used to compare the outcomes between the groups.

FINDINGS

After the intervention, based on ANCOVA test with adjusting the baseline values, mean scores of stress (mean difference (MD): -10.75; 95% confidence interval (95% CI): -11.77 to -9.72; P < 0.001), state anxiety (MD: -14.36; 95% CI: -15.7 to -12.7; P < 0.001) and trait anxiety (MD: -12.8; 95% CI: -14.4 to -11.1; P < 0.001) were significantly lower in CBT group compared to the control group. Also mean score of quality of life (MD: 9.82; 95% CI: -6.74 to -12.90; P < 0.001) was significantly higher in CBT group compared to the control group.

CONCLUSION

Based on the results, group CBT is effective in reducing stress and anxiety and improving the quality of life of mothers of girls with precocious puberty symptoms. However, more studies are required to make a definite conclusion in this field.

Complementary and alternative medicine use among people living with HIV in Shiraz, Southern Iran

Background

Living with HIV requires lifelong care to support engagement with and adherence to antiretroviral therapy. The Middle East and North Africa region provides access to ART, but research is lacking on the lived-experiences of people living with HIV. Globally, complementary and alternative medicine (CAM) is increasingly used by patients who need support alongside receiving medical treatment for chronic conditions. This study aims to examine the frequency and reasons behind the use of CAM, as well as identify its associated factors among people living with HIV in Shiraz, Iran.

Methods

In this cross-sectional study, a total of 320 patients (aged 18-70 years) with a confirmed diagnosis of HIV residing in Fars province and diagnosed between 1999 and 2019 were recruited randomly through their clinical record numbers from five HIV treatment centers. They were surveyed on their quality of life and CAM use via the Short-Form Health Survey questionnaire (SF-36) and a semi-structured survey of "CAM use." The data analysis for this study involved the use of Chi-squared test, independent t-test, and multiple logistic regression model.

Results

Of 287 patients, 89.22% reported using CAM in the previous year. CAM use was more prevalent among those with a family history of CAM use (94.3% vs. 81.8%, p = 0.023). Frequent reasons for using CAM were reported to be sexual dysfunction (32.4%), depression (28.3%), thirstiness (23.3%), and nausea (17.5%). Quality of life, as measured via the SF-36 questionnaire in all its 8 sub-domains, did not differ among those who used CAM versus those who did not (61.5 ± 27.6 vs. 58.1 ± 30.9, p = 0.626).

Conclusion

CAM was used among a majority of people living with HIV in Shiraz, Iran. People who used CAM appeared to experience a similar quality of life relative to those who did not use CAM. Future studies on the modalities of engagement with CAM can improve patient-physician shared decision-making and increase lifelong care options for people living with HIV.

The effect of a topical formulation from Lawsonia inermis L. (henna) on pain intensity in patients with chronic sciatica: A randomized double-blind clinical trial

ETHNOPHARMACOLOGICAL RELEVANCE

Chronic sciatica (CS) is a common condition of disability and pain. Lawsonia inermis L. (henna) is a medicinal plant that is commonly recommended in traditional Persian medicine textbooks for pain relief in patients with sciatica, particularly in the form of oil.

AIM OF THE STUDY

This research was designed to investigate the efficacy of a topical formulation from henna on pain intensity in patients with CS.

METHODS AND MATERIALS

In a randomized, double-blind clinical study, 81 patients were randomly allocated to three groups to receive the topical henna formulation (aqueous extract of henna in sesame oil), sesame oil, or placebo, three times daily, for four weeks. The patients were assessed by visual analog scale (VAS), 36-item short form health survey (SF-36), and Oswestry disability index (ODI).

RESULTS

There was a significant decrease in mean VAS in henna oil compared to sesame oil (p = 0.004) and placebo (p = 0.004). Significant improvements in total SF-36 scores were observed in henna oil and sesame oil compared to placebo (p = 0.011 and p = 0.025, respectively). Furthermore, ODI significantly decreased in henna oil compared to sesame oil (p < 0.001) and placebo (p = 0.005).

CONCLUSION

Henna oil seems to be an effective treatment to reduce pain intensity in patients with CS. Moreover, it improves quality of life and functional ability. Further randomized controlled trials with longer intervention periods are recommended to confirm this efficacy.

Translation and psychometric evaluation of the Persian version of Knee Outcome Survey-Activities of Daily Living Scale (KOS-ADLS)

BACKGROUND

The present study aimed to translate and validate the Knee Outcome Survey-Activities of Daily Living Scale (KOS-ADLS) in Iran.

METHODS

Following standard forward and backward translation procedure, content and face validity were tested by specialists and a sample of 32 patients. Then, in a cross sectional study, a sample of patients with knee disorders, recruited through simple sampling, completed the KOS-ADLS and the Short-Form Health Survey (SF-36) in their first visit to physiotherapy clinics in Tehran. Regarding construct validity, the Spearman's correlation (rs) and one-way ANOVA were employed to evaluate the correlations between the Persian KOS-ADLS and SF-36 subscales (convergent validity) and known groups comparison, respectively. Test-retest reliability and internal consistency were evaluated by intraclass correlation coefficient (ICC) and the Cronbach's α coefficient.

RESULTS

In total 101 patients were included in the study. The mean age of patients was 42.39 (SD = 9.2). The finding indicated that the KOS-ADLS had strong correlations with SF-36 physical functioning, bodily pain subscales, and also physical component summary while it had lower correlations with other subscales of the SF-36 as expected. The KOS-ADLS was able to differentiate between the subgroups of patients who differed in BMI. The acceptable level of intraclass correlation coefficient (ICC = 0.91) and Cronbach's α coefficient (α = 0.91) was obtained for the Persian KOS-ADLS. Also no floor and ceiling effects were observed for the questionnaire.

CONCLUSIONS

The Persian version of KOS-ADLS was found to be a reliable and valid outcome measure for assessing daily living activities in patients who suffer from knee pathological conditions.

Translation and evaluation of psychometric properties of the Persian version of the Hypertension Self-Care Activity Level Effects (H-SCALE)

BACKGROUND & OBJECTIVES

Hypertension is a major cause of cardiovascular disease and premature death worldwide. Managing hypertension through self-care practices is considered one of the most effective strategies. However, to accurately assess the self-care status of individuals with hypertension, a valid and reliable tool is necessary. This study aimed to evaluate the psychometric properties of the Persian version of the Hypertension Self-Care Activity Level Effects Questionnaire.

METHODS

Present methodological study was conducted on 218 patients with hypertension visiting the Clinic of Qom educational and medical centers. Subjects were selected with convenience sampling. Data were collected using the H-SCALE, and a demographic questionnaire. The translation was done from the recommended backward-forward method according to the WHO protocol. After that, face and content validity were applied, along with construct validity involving a comparison of known groups and confirmatory factor analysis. To test reliability, Cronbach's alpha was used. Data analysis was performed by SPSS and smart-PLS software.

RESULTS

The factor loadings of the self-care behaviors questionnaire were significant in all constructs, and were higher than 0.5 except for three items. The known-groups method showed that the self-care score of patients with controlled blood pressure was significantly higher than those with uncontrolled blood pressure. The extent of average variance extracted (AVE) of the majority of the constructs in the questionnaire was greater than 0.5 and, the composite reliability was greater than the AVE, indicating a good convergent validity. The divergent validity of the questionnaire was confirmed using the Fornell-Larcker criterion and the heterotrait-monotrait ratio (HTMT). Cronbach's alpha coefficient, combined reliability, and communalities index were optimal.

CONCLUSION

According to research findings, the Persian version of the questionnaire has good validity and reliability that can be used as a tool to measure the level of self-care of hypertension by health care providers.

Self-rated health and quality of life in female sex workers with substance use disorders in Tehran, Iran

BACKGROUND

While self-rated health (SRH) and quality of life (QoL) has been associated with substance use disorders (SUDs) in sex-working populations, little is known about this association in Iran. This study aimed to assess QoL and SRH in Iranian female sex workers (FSWs) in Tehran.

METHOD

FSWs were recruited using convenience sampling methods from substance abuse treatment centers in Tehran that exclusively provided services for women. Participants completed an interviewer-administered demographic questionnaire in Persian and the Iranian version of the Short Form Health Survey (SF-36). Descriptive analyses, means and standard deviations; frequency and percentages, t-test and one-way ANOVA, and Chi-square tests were utilized to analyze the data.

RESULTS

The mean age among 161 participants clinically diagnosed with SUD was 34.09 years (SD 7.97; range: 18-57). The total mean QoL score was 41.03 (SD: 12.92). The highest and lowest mean scores were observed in the physical functioning (52.23) and role emotional (26.64) dimensions, respectively. Significant differences (p < 0.05) in QoL were observed according to education and marital status, and the average QoL score was lower in women who reported permanent marriages and women who were illiterate. The average score of QoL was significantly higher in employed women. Overall, 51.6% of the women rated their health as sub-optimal, with divorced participants and women who were illiterate more likely to rate their health as sub-optimal (p < 0.05).

CONCLUSION

Results emphasize the need for mental, physical, and sexual health screening and gender-specific interventions to improve QoL in this population. Further investigation may elucidate the consequences of poor SRH and QoL on SUD treatment adherence, sexual risk behavior, and morbidity and mortality in FSWs.

Predictors of fear control related to COVID-19 among older population: an investigation on COVID-19 risk perception and health related quality of life during the pandemic

BACKGROUND

The aim of this study was to examine the role of demographic characteristics, general health and health related quality of life on the fear control. Also, the aim of study was to explore how older people percept the COVID-19 pandemic by using the component of the expanded parallel process model (EPPM), and how the possible perception may contribute to probable behavior responses to prevention and control of COVID-19.

METHODS

The present study is a cross-sectional study that was conducted in Tabriz, a city in north of Iran from February to April 2021, the period that correspond with the fourth wave of COVID-19. To collect information, the Covid-19 risk perception questionnaire (based on EPPM model including efficacy, defensive responses, and perceived threat) and health related quality of life (HQOL) Short Form-36 questionnaire were used. Discriminate value was calculated to estimate fear control and danger control. Univariate and multivariable logistic regression were calculated to examine the effect of demographic characteristics, general health and health-related quality of life on the fear control.

RESULTS

The mean age of the 350 participants was 67.9 (6.4) years. A total of 83.1% of participants were engaged in danger control processes and 16.9% in fear control processes. According to the multivariable results, significant predictors for fear control were: gender 1.57 (95% CI 1.05-2.34, 0.025), education 7.38 (1.42-38.35, p = 0.017), economic status 1.31 (0.4-0.63, p = 0.029), and significant protective factors for fear control were: body pain 0.97 (0.94-0.99, p = 0.041), general health 0.96 (0.93-0.98, p = 0.032), physical health 0.94 (0.90-0.98) and total quality of life 0.024 (0.89-0.98).

CONCLUSIONS

Strong associations of fear control were found with being female, being illiterate, and having a good economic status and also body pain, general health, physical health and total HQOL were significantly associated with danger control. Since, most of elderly populations have adequately higher perceptions of efficacy to counteract their threat perceptions to continue motivating these older people to engage in COVID-19 self-protective behaviors, it is necessary to emphasis on the susceptibility of target population and the severity of the COVID-19 threats.

The impact of inhibitors on the quality of life in patients with hemophilia

Objective

To investigate the association of health-related quality of life in hemophilia patients with inhibitor and clinical and demographic characteristics.

Methods

In this multi-center cross-sectional study, 41 male patients with hemophilia A were investigated from May to October 2021. All patients were registered at the Hemophilia Clinic affiliated with Shiraz and Zahedan Universities of Medical Sciences in Iran. Health-related quality of life of the patients was evaluated by the Short Form-36 questionnaire.

Results

The patients' mean ± SD of age was 36.9 ± 13.2 (range: 18-76) years. Eleven patients (26.8%) were inhibitor positive. In univariate analysis, physical function, mental health dimension, and total Short Form-36 scores were significantly lower in the inhibitor-positive patients (p < 0.001, p = 0.045, and p = 0.035, respectively). Moreover, patients with severe disease showed significantly lower scores in physical function (p < 0.001), physical health dimension (p = 0.018), and total Short Form-36 (p = 0.031) than those with mild and moderate hemophilia. Also, blood-borne infections showed a significant association with lower score in physical health dimension (p = 0.038). In addition, annual bleeding rate showed significant negative correlations with physical health dimension (r_s = -0.609, p < 0.001), mental health dimension (r = -0.317, p = 0.044), and total Short Form-36 (r = -0.455, p = 0.003) scores. In multiple linear regression analysis, disease severity revealed a significant negative relationship with scores in physical function (p = 0.001), role physical (RP) (p = 0.015), general health (GH) (p = 0.006), physical health dimension (p = 0.006), and marginally in total Short Form-36 score (p = 0.054). Also, age of the patients showed a significant negative association with physical function and GH scores (p < 0.001 and p = 0.015, respectively).

Conclusion

Disease severity and age were shown as independent factors affecting health-related quality of life, but inhibitor alone was not an independent influencing factor. Reduced health-related quality of life was also observed in hemophilia patients with higher annual bleeding rate and blood-borne infections. Therefore, it is necessary to pay more attention to these subgroups. Further studies with larger sample size are needed for more accurate results.

Health-Related Quality of Life and Life Satisfaction in a Greek Refugee Accommodation Center

Introduction In recent years, a large number of refugees have crossed the Greek borders. The aim of this study was to estimate the health-related quality of life (HRQoL) and life satisfaction (LS) of refugees and asylum seekers residing in the Vagiochori Accommodation Center. Methods The Short Form-36 (SF-36) survey tool and the Satisfaction With Life Scale (SWLS) were employed for the analysis. The sample consists of 144 individuals with an average age of 39.4 years, most of which are Afghans, married, and have a secondary education level. Non-parametric tests examined the association of respondents' demographics and health-related and residence-related characteristics with the physical component scale (PCS) and mental component scale (MCS) of SF-36 and SWLS. Regression analysis was used to examine the effect of these variables on dependent scales. Results HRQoL and LS of the participants were poor (median scores: PCS = 44.91, MCS = 42.05, and SWLS = 12.00). Age, gender, education, marital status, and specific health-related and residence-related characteristics were associated with HRQoL (p < 0.05). Marital status and specific health-related and residence-related characteristics were associated with SWLS. Conclusion In summary, social support, legal counseling, and a better understanding of refugees' concerns are required to improve refugees' and asylum seekers' HRQoL and LS.

Estimation of global rating changes in quality of life and marital satisfaction among reproductive age women in Iran and Afghanistan before and after COVID-19 pandemic

BACKGROUND

Quality of life and marital satisfaction are important components of reproductive-age women's health. This study aimed to compare the quality of life and marital satisfaction in women of reproductive age in Iran and Afghanistan before and after the COVID-19 pandemic.

METHODS

This was a cross-sectional study on a sample of Iranian and Afghan women of reproductive age. To collect the data, the 12-item short-form health survey (SF-12) and the Enrich marital satisfaction scale were used to assess the quality of life and marital satisfaction, respectively. In addition, the Global Rating of Change (GRC) was used in order to evaluate the quality of life and marital satisfaction compared to before the COVID-19 pandemic. Data were evaluated descriptively through statistics including sing t-test, and chi-square, Logistic regression was performed to assess the relationship between outcome variables and independent variables.

RESULTS

In all 599 reproductive-age women (300 Iranian, and 299 Afghan) were studied. After adjusting for demographic variables, no significant difference was observed between the two groups for the physical component (P = 0.05) and mental component summary scores of quality of life (P = 0.166) as measured by the SF-12. The majority of Iranian women reported that their quality of life was worsened compared to before the pandemic (57.2%), while in the Afghan group, a higher percentage declared that it was unchanged (58.9%). The mental component of quality of life had no significant relationship with any of the independent variables including nationality. In contrast, the physical component quality of life had a significant relationship with nationality (P = 0.01). Iranian women had more marital satisfaction than Afghan women (P<0.001) and marital satisfaction had a significant relationship with nationality (P<0.001). Most women in both groups (70% of Iranian and 60% of Afghan women) declared that their marital satisfaction unchanged compared to before the COVID-19 pandemic.

CONCLUSION

The results showed that the quality of life of Iranian and Afghan women of reproductive age was almost the same before and after the pandemic. However, Iranians scored lower on the mental component summary and Afghans reported lower scores on the physical component summary. Marital satisfaction of Afghan women was much lower than that of Iranian women. The findings suggest the need for serious attention by health care authorities. Providing a supportive environment might be considered a primary step towards a better quality of life for these populations.

An Empirical Study of Feedforward Control in Unplanned Extubation of Nasogastric Tube

Objective

To explore the effect of feedforward control on reducing the incidence of unplanned extubation and improving the quality of catheter nursing.

Methods

A total of 186 patients with nasogastric tube after gastrointestinal surgery in the eastern region of our hospital from September 2020 to September 2021 were selected as the control group; 186 patients with nasogastric tube after gastrointestinal surgery in the western region of our hospital at the same period were selected as the experimental group. The influencing factors of unplanned extubation in patients with long-term postoperative nasogastric tube were analyzed, and effective preoperative and postoperative health education was conducted. The ratio of unplanned extubation of nasogastric tube and nursing satisfaction of patients in the two groups were compared.

Results

Patient constraint, perceived pressure score, anxiety score, nasal gastrointestinal canal health education feedback score and indwell tube comfort score were independent risk factors for unplanned extubation. The restraint rate and the incidence of unplanned extubation in the experimental group were lower than those in the control group after intervention, with statistical significance (P < 0.05). The nursing satisfaction of the experimental group was significantly higher than that of the control group after feedforward cognitive intervention. After intervention, serum albumin and gastric PH in the experimental group were significantly higher than those in the control group (P < 0.05).

Conclusion

The safe nursing management method of feed forward control can effectively reduce the incidence of unplanned extubation in inpatients, which is worth further promoting in nursing work.

Post-discharge health assessment in survivors of coronavirus disease: a time-point analysis of a prospective cohort study

PURPOSE

 The objective of this study was to quantitatively evaluate psychological and quality of life-related complications at three months following discharge in hospitalized coronavirus disease 2019 (COVID-19) patients during the pandemic in Iran.

METHODS

In this time-point analysis of prospective cohort study data, adult patients hospitalized with symptoms suggestive of COVID-19 were enrolled. Patients were stratified in analyses based on severity. The primary outcomes consisted of psychological problems and pulmonary function tests (PFTs) in the three months following discharge, with Health-related quality of life (HRQoL) as the secondary outcome. Exploratory predictors were determined for both primary and secondary outcomes.

RESULTS

283 out of 900 (30%) eligible patients were accessible for the follow-up assessment and included in the study. The mean age was 53.65 ± 13.43 years, with 68% experiencing a severe disease course. At the time of the final follow-up, participants still reported persistent symptoms, among which fatigue, shortness of breath, and cough were the most common. Based on the regression-adjusted analysis, lower levels of forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) ratio was associated with higher levels of depression (standardized β = - 0.161 (SE = 0.042), P = 0.017) and stress levels (standardized β =- 0.110 (SE = 0.047), P = 0.015). Furthermore, higher levels of anti-SARS-CoV-2 immunoglobulin-M (IgM) were associated with significantly lower levels of depression (standardized β = - 0.139 (SE = 0.135), P = 0.031).

CONCLUSIONS

There is an association between lung damage during COVID-19 and the reduction of pulmonary function for up to three months from acute infection in hospitalized patients. Varying degrees of anxiety, depression, stress, and low HRQoL frequently occur in patients with COVID-19. More severe lung damage and lower COVID-19 antibodies were associated with lower levels of psychological health.

Functional outcomes and quality of life after surgically treated tibial plateau fractures

BACKGROUND

Tibial plateau fractures (TPF) are uncommon and challenging for orthopedic surgeons with controversial reported outcomes. In this study, we aimed to evaluate the functional outcomes and quality of life (QOL) of patients with surgically treated TPF.

METHODS

A total of 80 consecutive patients and 82 controls participated in this case control study. The patients were all surgically treated in our tertiary center from April 2012 to April 2020. The functional outcome was evaluated using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) scale. Moreover, we used the Short Form 36 health survey (SF-36) health survey to evaluate the QOL.

RESULTS

No significant difference was observed in the overall mean SF-36 score in the two groups. We found a significant positive correlation between the scores of the SF-36 and WOMAC questionnaires (r = 0.642, p < 0.001) and between the ROM and the WOMAC questionnaire score (r = 0.478, p < 0.001). Further, ROM and SF-36 showed a weak positive correlation (r = 0.248, p = 0.026). Age had a weak negative correlation with the pain subscale of SF-36 (r = - 0.255, p = 0.22), even though it was not correlated with the total score or other subscales (p > 0.05).

CONCLUSION

QoL after TPF is not significantly different from that of a matched control group. Also, neither age nor BMI correlates with the QoL and functional outcome.

Effect of progressive muscle relaxation as an add-on to pulmonary telerehabilitation in discharged patients with COVID-19: A randomised controlled trial

BACKGROUND

and purpose: Most patients with coronavirus disease 2019 (COVID-19) experience persistent physical and psychological symptoms. This study aimed to investigate the effects of pulmonary telerehabilitation (PTR) combined with progressive muscle relaxation (PMR) on the physical and psychological outcomes of discharged patients with COVID-19.

MATERIALS AND METHODS

This randomised, assessor-blinded, parallel-group study was conducted in hospitals affiliated with Qom University of Medical Sciences between May and October 2021. Discharged COVID-19 patients aged 18-65 years were randomly assigned to two groups of 26 patients each. The experimental group underwent PTR and PMR for six weeks, while the comparison group received PTR alone. Primary (functional capacity) and secondary (dyspnoea, anxiety, depression, fatigue, sleep quality, and quality of life) outcomes were evaluated at baseline and after six weeks.

RESULTS

The experimental group showed significantly higher sleep quality (P = 0.001, 95% confidence interval [CI]: 1.20-4.09) and significantly lower fatigue (P = 0.041, 95% CI: 4.79-5.25) and anxiety (P = 0.001, 95% CI: 1.21-4.47) than the comparison group. No between-group differences were observed in terms of other outcomes (P > 0.05).

CONCLUSION

PTR coupled with PMR was more effective for promoting sleep quality and alleviating anxiety and fatigue than PTR alone.

Exploring the Relationship between Drug Addiction and Quality of Life in Herat, Afghanistan: A Cross-sectional Study

BACKGROUND

Addiction is a global public health problem, with over 36 million people suffering from drug-use disorders. Afghanistan, the world's leading opium producer, has high rates of drug use owing to the easy access to drugs in this country. This study aimed to investigate drug users' quality of life in Herat, Afghanistan, and identify the factors affecting it.

METHODS

This cross-sectional study examined health-related quality of life at six rehabilitation camps in Herat, Afghanistan, from March to July 2019, using the short form-36 questionnaire (SF-36). Data collected through interviews were analyzed using SPSS software (version 25).

FINDINGS

A total of 240 participants from six rehabilitation camps in Herat, Afghanistan participated in this study. The majority of participants (80%) rated their overall health as "good" or "very good". Men had higher average scores for mental health and vitality than women and those aged 30-39 had the highest quality of life. Statistically significant differences were found in bodily pain (P=0.038), vitality (P=0.042), and social functioning (P=0.046) among users of different types of drugs. Opium abusers had the highest scores for the physical and mental components, followed by heroin, methamphetamine, hashish, and crack abusers.

CONCLUSION

This study explored the relationship between drug addiction and quality of life in Herat, Afghanistan. The findings showed that young adults were more vulnerable to drug use and male addicts and opium users had the highest quality of life. This study can inform the development of effective rehabilitation programs but more research is needed for addiction treatment strategies.

Chronic heart failure health-related quality of life questionnaire (CHFQOLQ-20): development and psychometric properties

BACKGROUND

Health-related quality of life (HRQoL) is an important outcome indicator for chronic diseases. This study aimed to develop a new instrument for assessment of HRQoL in chronic heart failure (CHF) and evaluate its psychometric properties.

METHODS

This study included two steps of conceptualization and item generation, and assessment of the psychometric properties of an instrument for measuring HRQoL in patients with CHF. A sample of 495 patients with confirmed diagnosis of heart failure participated in the study. In addition to content validity, exploratory and confirmatory factor analyses, concurrent validity, convergent validity, known groups comparison were performed to assess construct validity. Internal consistency, and stability were estimated by the Cronbach's alpha, the MacDonal's Omega, and intraclass correlation coefficients.

RESULTS

The content validity of the developed chronic heart failure quality of life questionnaire was assessed by 10 experts. The exploratory factor analysis indicated a four-factor solution for the instrument containing 21 items that jointly accounted for 65.65% of variance observed. The confirmatory factor analysis confirmed the four factor solution with the following fit indexes (χ²/df = 2.214, CFI = 0.947, NFI = 0.91, TLI = 0.937, IFI = 0.947, GFI = 0.899, AGFI = 0.869, RMSEA = 0.063). However, at this stage one item was removed. The concurrent and convergent validity of the CHFQOLQ-20 were established using the Short Form Health Survey (SF-36), and the MacNew Heart Disease Quality of Life Questionnaire, respectively. The known-groups validity as assessed by using the New York Heart Association (NYHA) functional classification showed that the questionnaire discriminated well between patients who differed in functional classification. The internal consistency and test-retest reliability of the CHFQOLQ-20 were satisfactory, with a Cronbach's alpha and intraclass correlation coefficient (ICC) values of 0.93 and 0.84, respectively.

CONCLUSION

The results confirmed that CHFQOLQ-20 is a valid and reliable instrument for measuring quality of life (QoL) in patients with CHF. It is a short and easy-to-use instrument that is also capable of assessing the cognitive functioning, which has been overlooked in previous questionnaires.

Vitality Revisited: The Evolving Concept of Flourishing and Its Relevance to Personal and Public Health

Human flourishing, the state of optimal functioning and well-being across all aspects of an individual's life, has been a topic of philosophical and theological discussion for centuries. In the mid-20th century, social psychologists and health scientists began exploring the concept of flourishing in the context of health and high-level wellness. However, it is only in recent years, in part due to the USD 43 million Global Flourishing Study including 22 countries, that flourishing has entered the mainstream discourse. Here, we explore this history and the rapid acceleration of research into human flourishing, defined as "the relative attainment of a state in which all aspects of a person's life are good" by the Harvard University's Flourishing Program. We also explore the construct of "vitality", which refers to a sense of aliveness, energy, and motivation; we contend that this has been neglected in the flourishing movement. We explore why incorporating measures of vitality, together with a broader biopsychosocial approach, considers all dimensions of the environment across time (the total exposome), which will greatly advance research, policies, and actions to achieve human flourishing.

Sense of coherence or self-efficacy as predictors of health-related quality of life in sickle cell disease patients

Patients with sickle cell disease (SCD) suffer from impaired health-related quality of life (HRQoL). This study aimed to determine the level of HRQoL, sense of coherence (SOC), and self-efficacy (SE) in a sample of SCD patients, and to explore predictors of their physical and mental HRQoL. A cross-sectional descriptive study was conducted on 83 SCD patients of one university hospital. The data of the study was collected through Persian versions of the Short-Form Health Survey SF-36 (RAND 36-item), the Sense of Coherence Scale (SOC-13), and the Sickle Cell Self-Efficacy Scale (SCSES). The mean age of the patients was 26.34 ± 8.19 years old. Patients' mean scores for the Physical Component Summary (PCS), Mental Component Summary (MCS), SOC, and SCSES were 40.57 ± 17.18 (range: 0-100), 50.44 ± 17.95 (range: 0-100), 52.40 ± 15.35 (range: 13-91), 26.40 ± 6.96 (range: 9-45), respectively. Regression models showed that the level of the patients' SOC, was the main predictor of the MCS (β = 0.37, p < 0.001). However, the level of the patients' SE was the main predictor of the PCS (β = 0.30, p = 0.004). Also, "blood transfusion history" in patients was a common predictor for both the PCS (β =  - 0.28, p = 0.008) and the MCS (β =  - 0.29, p = 0.003). These results can assist nurses and clinicians to plan clinical interventions for SCD patients by focusing on increasing the level of the SOC and SE and improving SCD patients' HRQoL. Furthermore, measuring the level of the SOC and self-efficacy as screening tests are useful to find patients with a greater risk of impaired HRQoL.

Translation and validation of the Persian version of the scleroderma health assessment questionnaire (SHAQ)

The present study aimed to translate and validate the Scleroderma Health Assessment Questionnaire (SHAQ) for Persian-speaking patients (SHAQ-P), using a cross-sectional study. This cross-sectional study included SSc patients with 2013 ACR/EULAR criteria. The SHAQ was translated using a "forward-backward" method. HAQ-DI and SSc-HAQ scores were calculated from the patient-answered questionnaires. Rheumatology experts assessed the face and content validities of the SHAQ-P. Psychometric properties of the SHAQ-P were then assessed: Structural validity was analyzed using principal component factor analysis. Discriminant and convergent validities were measured on subgroups of the initial patient population. Test-retest reliability was measured on patients who filled the SHAQ-P again after 1 month. The Scale-CVI-average (S-CVI/Ave) score for content validity was 88.7%. Face validity was measured to be 68.17% using the QQ10 questionnaire. Factor analysis revealed a two-factor structure with 20 out of 26 questions loading on the first factor (N = 285). One-way ANOVA showed that patients with a higher number of involved organs had higher average HAQ-DI and SSc-HAQ-scores (N = 60, P = 0.019 and 0.023, respectively). HAQ-DI and SSc-HAQ-scores were significantly correlated with the physical component score of SF36 (N = 31, correlation coefficient =  - 0.65 and  - 0.72, respectively). Reliability testing after one month demonstrated that HAQ-DI and SSc-HAQ-scores were significantly correlated with their initial (N = 40, correlation coefficient = 0.86 and 0.84, respectively), proving that the Persian SHAQ was a valid and reliable questionnaire to evaluate scleroderma patients' quality of life.
