The Short Form Health Survey (SF-36): translation and validation study of the Iranian version

Determinants of health-related quality of life in patients with celiac disease: a structural equation modeling

Background

We aimed to investigate the determinants of Health-related quality of life (HRQOL) in Iranian patients with celiac disease (CD) using the structural equation modeling (SEM).

Methods

In the present cross-sectional study, a total of 170 adult patients with CD were recruited. The information regarding adherence to diet, symptom severity, and HRQOL were collected using the celiac disease adherence test (CDAT), gastrointestinal symptom rating scale (GSRS), and SF-36 questionnaire respectively. Association between various studied variables and HRQOL was assessed using SEM. The standardized regression weights were used to assess total, direct and indirect effects. The model fit indices were used to assess the “goodness of fit” between the hypothesized models.

Results

The mean age of participants was 37.57 ± 9.59 years. The results of SEM indicated that the overall fit of our model was acceptable. Adherence to the diet, GSRS score, occupation, and education level was significantly related to PCS of SF-36; and adherence to the diet, GSRS score, and education level were significantly correlated with MCS of SF-36. The analysis of indirect associations indicated that only adherence to diet indirectly via GSRS score was significantly associated with PCS and MCS of SF-36.

Conclusion

In adult patients with celiac disease, HRQOL was associated with age, education, adherence to GFD, and GSRS score. Additionally, occupation and disease duration were associated with HRQOL only in women and men respectively.

The relationship between common foot problems with falls and quality of life in older people

OBJECTIVES

To evaluate the relationship between a number of prevalent foot problems in older people and their history of falls and quality of life. To examine the relationship between timed up and go (TUG) test time and ankle muscles' strength.

METHOD

In this cross-sectional observational study on a convenient sample of 350 people 65 years and older, direct logistic and hierarchical regressions were used to assess the relation of self-reported falls and quality of life with hallux valgus, oedema, sensory loss and callus. The correlation coefficients were calculated to measure the relationship between TUG test time and ankle muscle strength.

RESULTS

Moderate negative correlations were measured between ankle muscles' strength and TUG time (r_Dorsiflexors  = -0.42 p = 0.000, r_{Plantar flexors}  = -0.45 p = 0.000). The odds ratio extracted from logistic regression for foot pain was 3.05 (p = 0.000, 95% CI: 1.8-5.1). The results of the hierarchical regression showed that oedema had the highest contribution to depicting the quality of life (standardised B = -0.22, p = 0.001), followed by foot pain (beta = -0.178, p = 0.004) and plantar sensory loss (beta = -0.143, p = 0.019).

CONCLUSION

The results of this study highlight the importance of foot problems in older people. Foot pain showed relationship with self-reported fall experience. Oedema and foot pain had negative impact on quality of life. Ankle muscles' strength may affect balance in older people. However, because of the small effects sizes and wide confidence intervals, the results should be interpreted cautiously.

The impact of psychological factors on bereavement among frontline nurses fighting Covid-19

The COVID-19 pandemic has considerably changed the workplace and social relationships of nurses. As potential factors, uncertainty, stigma, and exposure of nurses' families to risk have disturbed the process of providing healthcare services for patients infected by COVID-19. Accordingly, this study aimed at determining the impact of psychological factors on stigma among frontline nurses fighting COVID-19. The extant paper was carried out based on the descriptive-analytical method for April-June 2020. A total of 312 nurses working in educational-medical centers in Ardabil, Iran, were selected using the census method to participate in this research. To collect data, demographic features, stigma, mental health, perceived stress, and hardiness questionnaires were used. The collected data were analyzed using statistical correlation tests, multivariate regression, and descriptive tests through SPSS v.22 Software. The mean score of stigma in nurses equaled 28.36 ± 10.55. Results of the correlation coefficient showed a positive relationship between the mean score of stigma and stress (P ≤ 0.01) as well as the negative relationship between mental health and hardiness (P ≤ 0.01). Multivariate regression analysis indicated that mental health could be the predictor of stigma. Therefore, these factors should be identified and controlled to mitigate stigma under such critical circumstances.

Study protocol for a randomized controlled trial to improve the quality of life of housewives with musculoskeletal disorders: a health promotion intervention based on a participatory ergonomic approach-the Housewives Ergonomic Intervention (HEI) trial

Background

A variety of household chores expose women to a variety of biomechanical and psychosocial risk factors. A result of this is many housewives with musculoskeletal disorders. Given the interactive effects of these risk factors, it is necessary to consider multiple strategies to mitigate their effects. Accordingly, the present study will investigate the impact of a health promotion training program based on a participatory ergonomic approach towards a reduction in the prevalence of musculoskeletal disorders and an improvement in the quality of life of housewives.

Methods

Iranian housewives aged 20–65 years currently attending a specialist health clinic due to a painful musculoskeletal complaint will be invited to join the study. Recruitment will continue until a sample of 160 women provides informed consent to participate. The study will be conducted using a mixed-methods protocol in two phases. In the first phase, psychosocial and biomechanical risk factors will be identified using a qualitative approach. In the next phase, the results from the qualitative approach will be used to develop a conceptual framework based on health promotion theories and an intervention program based on a participatory ergonomic approach designed. Participants will be randomly allocated into one of four groups: (1) biomechanical intervention group, (2) psychosocial intervention group, (3) multidisciplinary intervention group (both biomechanical and psychosocial intervention), and (4) a control group. Data will be collected using Rapid Entire Body Assessment (REBA), Visual Analog Scale (VAS), Work Ability Score (WAS), Hospital Anxiety and Depression Scale (HADS), and the 36-item Short-Form health survey (SF-36) at baseline in 3-month and 6-month follow-up assessments. The impact of the three interventions on musculoskeletal disorders, work ability, stress, and quality of life will then be evaluated.

Discussion

The study will provide a practical approach to reducing stress, reducing musculoskeletal disorders, enhancing the ability to work, and improving the quality of life of women with musculoskeletal disorders associated with housework. If the designed interventions in the present study are effective, they will have the great practical potential for generalization to all housewives.

Comparison of Outcomes with Midodrine and Fludrocortisone for Objective Recurrence in Treating Syncope (COMFORTS trial): Rationale and design for a multi-center randomized controlled trial

BACKGROUND

The cornerstone of the treatment of vasovagal syncope (VVS) is lifestyle modifications; however, some patients incur life-disturbing attacks despite compliance with these treatments which underscores the importance of pharmacological interventions.

METHODS

In this open-label multi-center randomized controlled trial, we are going to randomize 1375 patients with VVS who had ≥2 syncopal episodes in the last year into three parallel arms with a 2:2:1 ratio to receive midodrine, fludrocortisone, or no medication. All patients will be recommended to drink 2 to 3 liters of fluids per day, consume 10 grams of NaCl per day, and practice counter-pressure maneuvers. In medication arms, patients will start on 5 mg of midodrine TDS or 0.05 mg of fludrocortisone BD. After one week the dosage will be up-titrated to midodrine 30 mg/day and fludrocortisone 0.2 mg/day. Patient tolerance will be the principal guide to dosage adjustments. We will follow-up the patients on 3, 6, 9, and 12 months after randomization. The primary outcome is the time to first syncopal episode. Secondary outcomes include the recurrence rate of VVS, time interval between first and second episodes, changes in quality of life (QoL), and major and minor adverse drug reactions. QoL will be examined by the 36-Item Short Form Survey questionnaire at enrollment and 12 months after randomization.

CONCLUSION

The COMFORTS trial is the first study that aims to make a head-to-head comparison between midodrine and fludrocortisone, against a background of lifestyle modifications for preventing recurrences of VVS and improving QoL in patients with VVS.

American Orthopedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal Joint Scale: A Cross-Cultural Adaptation and Validation Study in the Persian Language

We evaluated the reliability and validity of the Persian translation of the American Orthopedic Foot and Ankle Society hallux metatarsophalangeal-interphalangeal joint scale (AOFAS Hallux MTP-IP). The translated AOFAS Hallux MTP-IP scale form was completed for 101 patients with hallux deformities; the subjective questions were answered by the patients, whereas the orthopedic foot and ankle surgeon and his assistant answered the objective questions. The validated Persian version of the 36-Item Short Form Survey Instrument (SF-36) was used for validity assessment. Eighty-five females and 16 males with a mean age of 49 years were enrolled. Hallux valgus and hallux rigidus was the diagnosis in 73 and 28 patients, respectively. Intrarater reliability had a high level of correlation (rho >0.6) for all subscales and total score. Although the correlation between the total score of the AOFAS Hallux MTP-IP scale and role: physical subscale of SF-36 was the highest (rho = 0.47), the total score of AOFAS Hallux MTP-IP scale and the other 7 domains of SF-36 had a correlation ranging between -0.17 and 0.43. Moreover, the correlation between total score of AOFAS-Hallux MTP-IP and SF-36 physical component summary scale was 0.50, which was higher than the correlation between total score of AOFAS and SF-36 mental component summary scale (rho = 0.35). Convergent validity was approved for MTP joint motion (0.59), IP joint motion (0.51), and callus (0.56) items of AOFAS-Hallux MTP-IP. Spearman's rank correlation coefficient between all items of the functional subscale of AOFAS Hallux MTP-IP scale with its own subscales was higher than the coefficient between these items and other subscales, including pain and alignment (discriminate validity). Floor and ceiling effects were calculated as 2% and 1%, respectively. Our findings indicate that the translated Persian version of the AOFAS Hallux MTP-IP scale is a reliable instrument, but its validity is not satisfactory.

The effects of aromatherapy massage with lavender essential oil on neuropathic pain and quality of life in diabetic patients: A randomized clinical trial

OBJECTIVE

to determine massage lavender essential oil on neuropathic pain and quality of life in diabetic patients.

METHODS

A randomized three-group control trial with the pre-post design was performed from 2019 to 2020 on 75 diabetic neuropathic patients. The patients were randomly allocated into aromatherapy (n = 26), placebo (n = 26), and control (n = 26) groups. Patients in the intervention group used 2.5 cc of 3% lavender oil on their feet as a gentle massage for 10 min every night before bedtime for a month. Data collected using the Visual analog scale (VAS), Douleur Neuropathic 4 (DN4) and Quality of Life Questionnaire (SF36).

RESULTS

The mean difference of pain scores in short-term and long-term in the aromatherapy group was significantly reduced compared to the placebo and control groups (P < 0.001). In addition, after four weeks, a significant increase was found in the QoL domains in the aromatherapy group (P < 0.001).

CONCLUSION

Aromatherapy massage with lavender oil helped reduce neuropathic pain two to four weeks after the intervention and improved the patients' QoL without causing any side effects. Thus, nurses are recommended to use it as a complementary method to reduce neuropathic pain and improve patients' QoL.

Adjuvant use of melatonin for relieving symptoms of painful diabetic neuropathy: results of a randomized, double-blinded, controlled trial

PURPOSE

The trial aimed to investigate the effectiveness of exogenous melatonin as an adjuvant to pregabalin for relief of pain in patients suffering from painful diabetic neuropathy (PDN).

PATIENTS AND METHODS

This randomized, double-blind, placebo-controlled trial was carried out between October 2019 and December 2020 in an outpatient specialty clinic in Iran. One-hundred-three type 2 diabetic patients suffering from PDN were randomized into either the melatonin group (n = 52) or the placebo group (n = 51). Besides pregabalin at a dose of 150 mg per day, patients started with melatonin or an identical placebo, at a dose of 3 mg/day at bedtime for 1 week, which was augmented to 6 mg/day for further 7 weeks. The primary outcomes were changes in mean NRS (numerical rating scale) pain score from baseline to endpoint and responder rate (patients with a reduction of 50% and higher in average pain score compared with baseline). Secondary endpoints were changes in mean NRS pain-related sleep-interference score, overall improvement evaluated by Patient and Clinical Global Impressions of Change (PGIC, CGIC), and impact of the intervention on patient's Health-related quality of life (QOL). All analyses were conducted on an Intention-to-Treat (ITT) analysis data set.

RESULTS

At the study endpoint, treatment with melatonin resulted in a considerably higher reduction in the mean NRS pain score in comparison with placebo (4.2 ± 1.83 vs. 2.9 ± 1.56; P-value < 0.001). In terms of treatment responders, a greater proportion of melatonin-treated patients satisfied the responder criterion than placebo-treated patients (63.5% vs. 43.1%). Melatonin also reduced pain-related sleep interference scores more than did placebo (3.38 ± 1.49 vs. 2.25 ± 1.26; P-value < 0.001). Further, at the endpoint, more improvement was also seen in terms of PGIC, CGIC, and Health-related QOL in patients treated with melatonin than placebo. Melatonin was also well tolerated.

CONCLUSION

The present results showed that melatonin as an adjunct therapy to pregabalin might be helpful for use in patients with PDN. However, confirmation of these results requires further studies.

Factors Associated With Lower Limb Injuries in Recreational Runners: A Cross-Sectional Survey Including Mental Aspects and Sleep Quality

Knowledge about prevalence and etiology of running-related injuries (RRIs) is important to design effective RRI prevention programs. Mental aspects and sleep quality seem to be important potential risk factors, yet their association with RRIs needs to be elucidated. The aims of this study are to investigate the epidemiology of RRIs in recreational runners and the association of mental aspects, sleep, and other potential factors with RRIs. An internet-based questionnaire was sent to recreational runners recruited through social media, asking for personal and training characteristics, mental aspects (obsessive passion, motivation to exercise), sleep quality, perceived health, quality of life, foot arch type, and RRIs over the past six months. Data were analyzed descriptively and using logistic regression. Self-reported data from 804 questionnaires were analyzed. Twenty-five potential risk factors for RRIs were investigated. 54% of runners reported at least one RRI. The knee was the most-affected location (45%), followed by the lower leg (19%). Patellofemoral pain syndrome was the most-reported injury (20%), followed by medial tibial stress syndrome (17%). Obsessive passionate attitude (odds ratio (OR):1.35; 95% confidence interval (CI):1.18-1.54), motivation to exercise (OR:1.09; CI:1.03-1.15), and sleep quality (OR:1.23; CI:1.15-1.31) were associated with RRIs, as were perceived health (OR:0.96; CI:0.94-0.97), running over 20 km/week (OR:1.58; CI:1.04-2.42), overweight (OR:2.17; CI:1.41-3.34), pes planus (OR:1.80; CI:1.12-2.88), hard-surface running (OR:1.37; CI:1.17-1.59), running company (OR:1.65; CI:1.16-2.35), and following a training program (OR:1.51; CI:1.09-2.10). These factors together explained 30% of the variance in RRIs. A separate regression analysis showed that mental aspects and sleep quality explain 15% of the variance in RRIs. The association of mental aspects and sleep quality with RRIs adds new insights into the multifactorial etiology of RRIs. We therefore recommend that besides common risk factors for RRI, mental aspects and sleep be incorporated into the advice on prevention and management of RRIs.

Psychosomatic symptoms questionnaire (PSQ-39): a psychometric study among general population of Iranian adults

BACKGROUND

Psychosomatic symptoms, characterized by physical-bodily complaints not fully explained by organic reasons, are highly prevalent. The present study aimed to culturally adapt and evaluate the psychometric properties of Psychosomatic Symptoms Questionnaire 39-item version (PSQ-39) among Iranian general adult population.

METHODS

This study included 996 Persian-speaking people, living in Isfahan, Iran. The translation of the PSQ-39 was performed using the forward-backward method. Test-retest reliability was evaluated through Intraclass correlation (ICC) coefficient and internal consistency by using Cronbach's α. Construct validity was investigated by using both exploratory (EFA) and confirmatory (CFA) factor analysis. Short Form Health Survey (SF-36) was used to assess divergent validity. Known-group validity was also assessed.

RESULTS

The Persian version of the PSQ-39 showed excellent test-retest reliability in all domains (ICCs: 0.95-0.99). The computed Cronbach's alpha coefficients for domains of PSQ-39 were in the range good to excellent. The PSQ-39 showed good known-group validity and differentiated patients from the general population (Area under the curve [AUC] of 0.78 (95% CI: 0.73, 0.84). Construct validity evaluated by EFA led to extraction of seven factors (Cardiorespiratory, musculoskeletal, psychological, gastrointestinal, general, body balance and Globus), and the CFA confirmed the adequacy of extracted factors by EFA (CFI = 0.91, TLI = 0.90, PCFI = 0.77, PNFI = 0.71, CMIN = 1413.18 (df = 654), CMIN/DF = 2.16, and RMSEA = 0.06). Significant negative correlations between all domains of PSQ and SF-36 revealed an acceptable divergent Validity.

CONCLUSIONS

The Persian version of the PSQ-39 is a reliable and valid questionnaire with applicability in a broad range of Persian language populations for assessing common psychosomatic symptoms in research as well as in clinical practice.

The Relationship between Experienced Respiratory Symptoms and Health-Related Quality of Life in the Elderly with Chronic Obstructive Pulmonary Disease

Background

Chronic obstructive pulmonary disease (COPD) is one of the diseases that usually present at an advanced age. Respiratory symptoms in patients with COPD are the most important for making treatment decisions and understanding the adverse effects on health-related quality of life (HRQoL). This study aimed to investigate HRQoL in elderly patients with COPD and examine the relationship between this in relation to respiratory symptoms experienced by them and their demographic characteristics.

Methods

This is a descriptive, correlational study of elderly patients with COPD who were hospitalized in five different hospitals in an urban area of Iran. A consecutive sampling method was used. Demographic data form, the respiratory symptoms component of St. George's Respiratory Questionnaire (SGRQ), and the Short Form 36 Health Survey Questionnaire (SF-36) were applied for data collection.

Results

The patients (n = 217) reported low HRQoL, and this impairment was more observed in the physical component. There was a significant inverse relationship between the experienced respiratory symptoms and physical (p=0.03) and mental (p < 0.001) components of HRQoL. Moreover, the female gender, the low level of education, the increased duration of the disease, the increased number of hospitalizations during the past year, and the use of two classes of drugs simultaneously were associated with the impaired HRQoL.

Conclusion

Our findings inform healthcare providers about the negative impacts of respiratory symptoms and other related factors on the HRQoL of elderly patients with COPD. Nurses and other healthcare providers should proactively identify respiratory symptoms and design appropriate caring strategies to improve HRQoL among this group.

The effectiveness of social media and in-person interventions for low back pain conditions in nursing personnel (SMILE)

AIM

To compare two educational approaches to reduce low back pain in nurses.

DESIGN

A community randomized controlled clinical trial.

METHODS

Data were collected with two interventions and a control arm between August 2018 and January 2019. Participants were recruited from three hospitals. Hospital 1 received an in-person educational programme, Hospital 2 received via the website and Hospital 3 received nothing. Statistical analysis was carried out with a follow-up of 3 and 6 months.

RESULTS

A total of 180 female nurses with low back pain participated in the study. Dimensions of the quality of life improved over 3 and 6 months, pain and disability decreased over 3 months in both intervention groups and over 6 months in the social media group.

CONCLUSION

Two educational approaches can be effective in decreasing pain, disability and improving quality of life. However, the findings suggest that the social media approach was more successful over the long-term and might be a better way to present the programme.

Development of the Quality of Life Questionnaire (SF-36) for Patients with β-Thalassemia Major and β-Thalassemia Intermedia Based on Extended Rasch Analysis

The quality of life (QoL) questionnaire (SF-36) contains 36 questions in eight subscales. It requires much time to fill in by the respondent. The objective of this study was to use Rasch models to develop a questionnaire that brings the desired outcome of the QoL of people. Therefore, a new questionnaire was provided that is more motivating and time-saving for respondents than SF-36. The QoL of life assessment data of 325 β-thalassemia major (β-TM) and β-thalassemia intermedia (β-TI) patients in Kerman, Iran, was used as research data. In this study, the appropriate questions were classified in a limited dimensional framework using the exploratory factor analysis (EFA). The correctness of the factor structure was assessed by confirmatory factor analysis (CFA). The quality of the questions was evaluated by Rasch modeling [partial credit model (PCM)] and item analysis to ensure the validity and reliability of the questionnaire. Finally, the Pearson correlation coefficient was used to compare the new questionnaire with the previous one. This process resulted in the development of a new questionnaire with five subscales and 20 questions. The construct validity of the new questionnaire was good. The reliability index of the questionnaire was 0.75, and the Pearson correlation coefficient between the QoL scores gained from the previous and the new questionnaires was 0.93 that indicates the strength of the correlation. The use of Rasch analysis in this study resulted in the development of a new reliable and valid questionnaire.

Evaluation of Disease Severity and Health-Related Quality of Life in Patients with Rheumatoid Arthritis Undergoing Total Knee Arthroplasty

;Background: The Total Knee Arthroplasty (TKA) is one of the most common surgical intervention in patients with osteoarthritis (OA) and rheumatoid arthritis (RA). Previous studies suggested a significant improvement in health status after TKA surgery. But we have little data about the Iranian population undergone TKA. In the current clinical study, we evaluated postoperatively health status using reliable tools of MOS SF-36 and WOMAC in OA and RA patients undergoing TKA.

METHODS

In this cohort study, patients with OA and/or RA who were candidates for TKA surgery were included. Using two reliable questionnaires, i.e., WOMAC and SF-36, the quality of life of patients was examined during a period of six months (three monthly intervals) after the surgery. All data were analyzed using IBM SPSS Statistics. Kolmogrov-Smirnov, Kendall's tau, chi-square test and K-related Non-parametric tests were used.

RESULTS

Of the 2126 patients who underwent TKA, there were 2024 diagnosed osteoarthritis and 102 validated RA over one year. The mean ± SD of age and the average BMI were 68.0 ± 7.0 BMI 28.5 kg/m2, respectively. Regarding comorbidities and concurrent disorders, about 14% of cases were diabetic, 42% had cardiovascular diseases, 3% had respiratory diseases, and 12% involved with gastrointestinal diseases. The result of SF-36 dramatically increased during follow up. The central distributions of all domains in the SF-36 questionnaire indicated that most scores increased during the time after surgery. As a consequence, WOMAC and MOS FS-36 indicated statistically significant changes after TKA for those who are suffering from RA or OA.

CONCLUSION

TKA is an effective surgical process, which improves the quality of life in OA and/or RA. In addition, WOMAC and SF-36 examining tools are likely reliable tools with similar results to assess patients' quality of life after TKA surgery.

Influential factors on quality of life in married Iranian women during the COVID-19 pandemic in 2020: a path analysis

Background

This study aimed to investigate the relationship between quality of life (QoL) with anxiety, depression, corona disease anxiety, sexual function (SF), and marital satisfaction (MS) in married women during the Covid-19 pandemic.

Methods

We performed a cross-sectional study involving n = 296 married women. We used the Short Form Health Survey (SF-12), Marital Satisfaction Scale (MSS), Female Sexual Function Index (FSFI), Hospital Anxiety and Depression Scale, and coronary disease anxiety questionnaire, as determinants of QoL for data collection. Data were analyzed using the Pearson correlation coefficient and path analysis.

Results

There was a relationship between the components of QoL with SF, anxiety, depression, MS, general health, and contamination obsessions. The results of path analysis also showed that that SF, MS, anxiety, general health, and corona-related anxiety have a direct effect on women’s QoL. General health has a more direct effect on QoL.

Conclusion

The results of this study could help in a plan to improve the QoL of women during the coronavirus epidemic.

The Effect of Aromatherapy Massage With Lavender and Citrus Aurantium Essential Oil on Quality of Life of Patients on Chronic Hemodialysis: A Parallel Randomized Clinical Trial Study

CONTEXT

Poor quality of life is a major problem in hemodialysis patients.

OBJECTIVES

This study was conducted to assess the effect of aromatherapy massage on hemodialysis patients' quality of life.

METHODS

In this parallel randomized clinical trial study, 105 hemodialysis patients who meet the inclusion criteria were assessed and assigned into intervention and control groups using block randomization. Participants in the intervention groups received aromatherapy massage with Lavender essential oil or Citrus Aurantium essential oil for four weeks (three times per week). For the control group, only foot massage was performed. The level of quality of life was measured by the 36-Item Short-Form Health Survey questionnaire (SF-36) before and after the intervention. Data analysis was performed using descriptive and inferential statistics (analysis of variance, chi-square, and Fisher's exact tests).

RESULTS

There was a significant difference between the mean score of quality of life in the Lavender essential oil group and Citrus Aurantium essential oil group with the control group after intervention. However, there was no significant difference between the mean score of quality of life in the Lavender essential oil group and Citrus Aurantium essential oil group after the intervention.

CONCLUSIONS

In this study, both aromatherapy massages have positive effects on the quality of life of hemodialysis patients. Therefore, nurses are advised to use these aromatherapy massages to improve the quality of life of hemodialysis patients.

The Actor-Partner Effects of Parenting Stress on Quality of Life Among Parents of Children with ASD: The Mediating Role of Mental Quality of Life

The present study investigated the actor-partner effects of parenting stress (PS) on quality of life (QoL) among parents (96 couples) of children with autism spectrum disorder (ASD). Data were collected using the QoL Scale and the PS Index. Structural equation modeling was also utilized to test the hypothesis. The results revealed the effects of PS in each parent on mental QoL of that parent. Maternal PS further shaped physical QoL in mothers. However, PS in one parent did not influence QoL of his or her partner. Accordingly, mental QoL had a mediating role between PS and physical QoL. It was ultimately suggested to take account of QoL among parents in addition to the treatment of children with ASD.

The Persian Translation and validation of the celiac disease quality of life questionnaire (CDQOL)

BACKGROUND

Considering the importance of having a celiac disease-specific measure of the quality of life (QOL) in Persian, the present study aimed to translate the celiac disease quality of life questionnaire (CDQOL) into Persian and evaluate its psychometric properties.

METHODS

In this cross-sectional study, the Forward-Backward translation method was used. The content validation ratio (CVR) and the content validity index (CVI) were used for content validity assessment. The construct validity was assessed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) on 220 celiac patients who were selected randomly from the celiac disease (CD) registry database. The correlations between the result of the Persian version of CDQOL (PCDQOL), self-rated QOL, and short form-36 (SF36) were analyzed using the Pearson correlation test. The internal consistency and test-retest reliability were measured through Cronbach's alpha and intraclass correlation coefficient (ICC).

RESULTS

In the present study, 220 celiac patients with a mean age of 35.54 ± 10.29 years participated. The mean CVI, CVR, and impact score of PCDQOL were 0.98, 0.96, and 4.82 respectively. Using EFA, four factors have extracted that had a good fit in CFA (Chi-square/DF = 1.74, RMSEA: 0.08, and CFI: 0.90, and NFI: 0.90). The results showed that there was a moderate to high correlation between PCDQOL, SF36 (r: 0.587, p = 0.02), and self-rated QOL (r: 0.64, p < 0.001). The questionnaire had high internal consistency (Cronbach alpha: 0.93) and test-retest reliability (ICC: 0.96 [0.86-0.99]).

CONCLUSION

The PCDQOL questionnaire could be used by physicians and nutritionists to assess HRQOL in celiac patients in Iran.

Can healthy life style predict successful aging among Iranian older adults?

Background: Successful aging is a prominent and worldwide theme in gerontology. However, until recently, only few studies were conducted about successful aging in Iran. This study examined whether a healthy lifestyle could predict successful aging among older Iranians.

Methods: This cross sectional and descriptive study included 975 older Iranians who were selected through a multistage cluster-quota method from the health centers of Shiraz, Iran. A 5-part questionnaire, including demographic characteristics, the Seniors’ Healthy Lifestyle, Barthel Index, the Diner Life Satisfaction and Quality of Life, was used to collect the data. A logistic regression analysis was used in data analysis; data were analyzed using SPSS 21; and significance level was set at α = 0.05.

Results: The prevalence of successful aging among older Iranians was calculated at 24.0%. Results of multiple logistic regression analysis revealed that age (95% CI = 1.129- 1.702 and OR = 1.352), gender (95% CI = 0.412-0.764 and OR = 0.687), education level (95% CI = 1.443 – 1.699 and OR = 1.454), job (95% CI = 1.063-1.413 and OR = 1.185), monthly income (95% CI = 1.355-4.055 and OR = 2.272), insurance (95% CI = 0.344-0.842 and OR = 0.540), source of income (95% CI = 1.014-1.298 and OR = 1.145), and healthy lifestyle (95% CI = 0.772 - 0.858 and OR = 0.814) were predictors for successful aging.

Conclusion: Findings indicated that successful agers were mostly younger men, with higher education level and monthly income, who had insurance and a job and a healthy lifestyle. Thus, to age successfully, one must maintain and improve healthy lifestyle to prolong one’s health.

The impact of computer-based cognitive training intervention on the quality of life among elderly people: a randomized clinical trial

Background

Through the process of normal aging, cognitive decline would cause a lower level of functioning in real life. This flow might interfere with health-related quality of life (QoL). The purpose of this study is to investigate the effect of computer-based cognitive intervention on increasing QoL of elderly people.

Methods

A total number of 52 community-dwelling older adults participated in this study. This community scored ≥ 21 in the Mini-Mental State Examination (MMSE) and a clock drawing test score ≥ 4 from health centers in Tehran, Iran. This study is a parallel group stratified randomized clinical trial. The intervention group received a 45-min cognitive training session twice a week for 10 sessions, using Attentive Rehabilitation of Attention and Memory (ARAM) software focusing on selective attention and working memory. QoL was evaluated as a primary outcome. The control group participated in educational workshops.

Results

From fifty-two persons, only one participant was excluded from the study in the intervention group during follow-up. Results revealed by increasing cognitive function, improvement occurred in QoL (F = 13.417, p value < 0.001, partial eta-squared = 0.324) as a primary outcome in the intervention group. Among eight domains of QoL, there was significant increasing in domain of role limitations due to emotional problems (F = 4.007, p value = 0.021, partial eta-squared = 0.059), social functioning (F = 2.423, p value = 0.044, partial eta-squared = 0.004), and role limitations due to physical health (F = 10.749, p value < 0.001, partial eta-squared = 0.026).

Conclusions

Based on the results, ARAM showed transition and long-term effects on QoL in elderly people by improving cognitive functions such as selective attention and working memory.

The Impact of Spiritual Care Skills on Quality of Life in Spouses of Veterans with Post-traumatic Stress Disorder: A Randomized Controlled Trial

Introduction: The wives of veterans are under great pressure because of their husbands 'physical and mental problems, and this can affect their mental health and quality of life. It seems that the training of some skills can have a significant impact on improving quality of life and reducing their mental burden. This study was conducted to determine the effect of spiritual care education in quality of life in wives of veterans with post-traumatic stress disorder (PTSD) that plays a major role in caring for them. Methods: This study was a quasi-experimental study in which 60 wives of PTSD-affected veterans in Ibn Sina hospital were selected and assigned randomly in two experimental and control groups. Spiritual care education was conducted in five sessions of two hours. Quality of life Questionnaire (SF-36) was used in this study. The questionnaire was implemented on participants of both groups in three stages: before, after and one months after the intervention (follow-up). Data were analysis using SPSS version 19. Results: The results of this study showed that spiritual care education could increase quality of life in the Wives of Veterans with Post Traumatic Stress Disorder and the subjects participating in the post-test had significantly higher quality of life. Conclusion: According to results of this, study that represent effect of spiritual care education on quality of life, so it is recommended spiritual care education can be used to improve the quality of life of people especially the families of veterans.

The Persian Brief Illness Perception Questionnaire: Validation in Patients with Chronic Nonspecific Low Back Pain

BACKGROUND

Illness perceptions may influence coping behaviors as well as treatment and recovery among patients with chronic pain including low back pain (LBP). These perceptions may vary across different conditions. The Brief Illness Perception Questionnaire (BIPQ) is used as an instrument to assess the patients' perception of illness. Although the BIPQ has been previously translated into Persian, its psychometric properties have not been evaluated among patients with chronic nonspecific LBP. The aim of this study was to determine the reliability and validity of the Persian BIPQ in patients with chronic nonspecific LBP.

METHODS

116 patients with chronic nonspecific LBP with a mean (standard deviation) age of 36.4 years (10.7) participated in this cross-sectional study. Fifty patients were reexamined after 10 to 12 days for test-retest reliability. Internal consistency reliability, construct validity, concurrent criterion validity, and structural validity were evaluated. The concurrent validity was examined by using the Short Form-36 Health Survey.

RESULTS

There were no floor and ceiling effects. Cronbach's alpha for the total score was 0.90. The intraclass correlation coefficient (ICC) for test-retest reliability was 0.90. The standard error of measurement and the minimal detectable change was found to be 3.26 and 9.04, respectively. The convergent correlations confirmed the construct validity. The concurrent criterion validity was demonstrated by significant negative correlations with the SF-36. The Exploratory Factor Analysis produced the 2 factors (emotional illness representations and cognitive illness representations) with an eigenvalue >1.0 that jointly accounted for 58.86% of the total variance.

CONCLUSION

The Persian BIPQ is a reliable and 2-factor instrument and can be used for assessing illness perception in patients with chronic nonspecific LBP.

Case Report: Expanding the Genetic and Phenotypic Spectrum of Autosomal Recessive Spastic Ataxia of Charlevoix-Saguenay

Autosomal recessive spastic ataxia of Charlevoix–Saguenay (ARSACS) is a rare neurodegenerative disorder caused by biallelic mutations in the SACS gene. Once thought to be limited to Charlevoix–Saguenay region of Quebec, recent evidence has indicated that this disorder is present worldwide. It is classically characterized by the triad of ataxia, pyramidal involvement, and axonal-demyelinating sensorimotor neuropathy. However, diverse clinical features have been reported to be associated with this disorder. In this report, we present the first Iranian family affected by ARSACS with unique clinical features (mirror movements, hypokinesia/bradykinesia, and rigidity) harboring a novel deletion mutation in the SACS gene. Our findings expand the genetic and phenotypic spectrum of this disorder.

Health literacy and quality of life among Iranian pregnant women: The mediating role of health locus of control

Background: Main health challenge of the 21st century is improving quality of life (QoL). This study aimed to investigate the mediating role of health locus of control (HLC) between health literacy and QoL among Iranian pregnant women. Methods: In this cross sectional survey, 400 pregnant women referred to the community health centers of Gonabad, Iran, and completed the demographic, health literacy, QoL, and multidimensional HLC questionnaires during 2015-2016. Descriptive statistics and structural equation modeling were conducted using SPSS 22.0 version and AMOS 24.0 software. Results: The findings showed that health literacy has a significant positive effect on the physical (β= 0.54, p< 0.001) and mental (β= 0.57, p< 0.001) health. Also, it has a significant positive effect on internal subscale (β= 0.42, p< 0.001) and a significant negative effect on the chance (β= -0.51, p< 0.001) and powerful others (β= -0.33, p< 0.001) subscale of HLC. From HLC subscales, internal HLC had a significant positive effect on physical (β= 0.26, p< 0.001) and mental (β= 0.12, p= 0.010) health, while the effects of chance and powerful others on QoL dimensions were not significant. The findings indicated that internal HLC is a partial mediator between health literacy and physical dimension of QoL. Conclusion: The results indicate that health literacy can be considered as an effective factor in HLC orientations and can improve QoL. This reflects the need for more attention on health literacy and the recognition of the type of HLC beliefs, especially the internal belief in health promotion programs for pregnant women.

Evaluation of the effect of curcumin and zinc co-supplementation on glycemic measurements, lipid profiles, and inflammatory and antioxidant biomarkers in overweight or obese prediabetic patients: a study protocol for a randomized double-blind placebo-controlled phase 2 clinical trial

BACKGROUND

The prevalence of prediabetes is increasing worldwide. Unfortunately, prediabetes is related to non-communicable diseases. A high risk of developing type 2 diabetes mellitus (T2DM) is reported in people with prediabetes. Curcumin, a polyphenol, might lead to its therapeutic role in obesity and some obesity-related metabolic diseases. Zinc is a trace element that plays a key role in the synthesis and action of insulin, carbohydrate metabolism, and decreasing inflammation. There has been no clinical trial of zinc and curcumin co-supplementation in patients with prediabetes. In previous studies, the single administration of zinc or curcumin has not been conducted on many of the studied markers in prediabetic patients.

METHODS

The purpose of this randomized double-blind placebo-controlled clinical trial is to investigate the effect of curcumin and zinc co-supplementation on glycemic measurements, lipid profiles, and inflammatory and antioxidant biomarkers among 84 prediabetic patients with body mass index (BMI) between 25 and 35. Also, liver enzyme, serum zinc, urine zinc, blood pressure, anthropometric parameters, quality of life, adherence to co-supplementation, the side effects of co-supplementation, physical activity, and dietary intake will be assessed. Women or men (18-50 years old for men and 18 years to before menopause for women) will be followed for 3 months (90 days). This study will be conducted at Yazd Diabetes Research Clinic, Shahid Sadoughi University of Medical Sciences.

DISCUSSION

A diet rich in antioxidants, polyphenols, and phytochemicals has been shown to have a beneficial role in prediabetes. According to the beneficial properties of curcumin or zinc and inadequate evidence, RCTs are needed to assess the effect of curcumin and zinc co-supplementation in native prediabetes patients. We hope the results of the present trial, negative or positive, fill this gap in the literature and facilitate the approach for a much larger, multi-center clinical trial. In conclusion, a synergic effect of co-supplementation along with a weight-loss diet may delay the progression to type 2 diabetes mellitus.

The Effect of the Teach-Back Method on Knowledge, Performance, Readmission, and Quality of Life in Heart Failure Patients

Background

Among chronic diseases, heart failure has always been a serious challenge imposing high costs on health systems and societies. Therefore, nurses should adopt new educational strategies to improve self-care behaviors and reduce the readmissions in heart failure patients. This study aimed to determine the effect of the teach-back method on knowledge, performance, readmission, and quality of life in these patients.

Methods

This clinical trial was conducted in patients with heart failure (n = 70) hospitalized in the internal wards of the Baqiyatallah al-Azam Medical Center in Tehran (2019). Routine discharge educations were provided in control patients. Self-care topics were taught to the intervention groups by the teach-back method. A cardiac self-care questionnaire was used to assess the knowledge and practice of patients immediately after intervention and three months after patient discharge. Also, SF-36 was presented to each patient. Readmission(s) and quality of life were followed up by telephone interviews three months after patient discharge. Repeated measures analysis of variance and related post-hoc tests were performed for within-group comparisons before, immediately after, and 3 months after teach-back education. Wilks' lambda multivariate tests were conducted for simultaneous comparison of quality of life subscales between intervention and control groups. Also, logistic regressions were after controlling for baseline measures and confounders.

Results

Findings showed significant improvement in the patients' knowledge and performance immediately after teach-back education, though this effect was slow in the long term after discharge. Also, the frequency of readmissions decreased and the quality of life (except physical function) increased in the patients through teach-back education. By controlling for the pretest effect, the posttest scores for the relevant components of the quality of life suggested improvement in both intervention and control patients. This improvement in the quality of life was confirmed by controlling for baseline measurements using binary logistic regression analysis.

Conclusion

Teach-back education improved patients' knowledge and performance, readmission frequency, and quality of life.

Effects of a Multicomponent Program on Fall Incidence, Fear of Falling, and Quality of Life among Older Adult Nursing Home Residents

Background

Falling is one of the most common problems in older adults and can lead to additional health problems. This study aimed to determine the effects of a multicomponent program on fall incidence and quality of life in older adult nursing home residents.

Methods

This was a quasi-experimental study with a pretest and post-test design. The study population comprised 55 older adults residing in nursing homes. The intervention was a multicomponent program including physical activities, training sessions, and physical environment modifications in nursing homes that was conducted for 8 weeks. The data collection tools included a socio-demographic characteristics form and questionnaires pertaining to the quality of life and fear of falls, which were completed by the participants before and after the intervention.

Results

The mean age of the participants was 68.48 years, and most (90%) were illiterate. We observed a significant difference between the mean number of falls and the scores for fear of falling before and after the intervention (p<0.001). We also observed a significant difference between the total quality of life scores and all of the related dimensions before and after the intervention, indicating that the quality of life of the older adults had improved after the intervention (p<0.001).

Conclusion

The results of this study indicated that the multicomponent fall prevention program was effective in improving the quality of life, fall rate, and fear of falling among older residents in nursing homes. Further studies are needed to explore the long-term effects of these interventions.

Serum inflammatory and oxidative stress biomarkers levels are associated with pain intensity, pressure pain threshold and quality of life in myofascial pain syndrome

OBJECTIVES

We aimed to determine the serum concentrations of some inflammatory and oxidative stress biomarkers in relation with pain intensity and quality of life in patients with myofascial pain syndrome (MPS) compared to healthy controls. This study is a case-control study. The participants were selected from MPS patients who referred to rehabilitation outpatient clinics of the Tabriz University of Medical Sciences, Iran.

RESULTS

Serum hs-CRP (4.68 ± 4.36 vs. 2.92 ± 4.55 g/mlµ respectively, p = 0.011), phospholipase A2 (PLA2) (6.81 ± 2.22 vs. 4.73 ± 2.97 pg/ml respectively, p < 0.001) and malondialdehyde (MDA) (2.63 ± 0.71 vs. 1.98 ± 0.90 nmol/ml respectively, p < 0.001) levels were significantly higher and serum total antioxidant capacity (TAC) (2.46 ± 0.49 vs. 2.83 ± 0.82 mmol/L respectively, p = 0.011) and superoxide dismutase (SOD) (78.89 ± 37.93 vs. 154.25 ± 115.93 U/ml respectively, p < 0.001) levels were significantly lower in the MPS patients compared to healthy controls. Serum high-sensitivity C-reactive protein (hs-CRP) level was significantly and positively associated with resting (r = 0.349, p = 0.019), activity (r = 0.295, p = 0.049) and night pain (r = 0.304, p = 0.043) intensities, pressure pain threshold (PPT) (r = 0.210, p = 0.047) and pain duration (r = 0.283, p = 0.007). Serum TAC level was significantly and negatively associated with resting pain intensity (r = -0.312, p = 0.037). Some scales and subscales of quality of life were positively correlated with serum TAC level and negatively associated with serum hs-CRP and PLA2 levels.

A Randomized Clinical Trial on the Effect of Biofeedback on Pain and Quality of Life of Patients With Chronic Coccydynia

Introduction

Pelvic floor muscles dysfunction is one of the most important etiologies of coccydynia; therefore, manual therapies have been proposed as the first line of treatment. The purpose of this study was to investigate the effect of biofeedback as a new approach in the treatment of coccydynia.

Methods

Thirty women were randomized into two groups. Both groups were injected with the corticosteroid. One group received pelvic floor muscle exercises plus biofeedback while the other group only performed exercises. The patient's pain was measured using the Visual Analog Scale (VAS) in the first visit and after 1, 2, and 6 months of follow-up as well as Dallas pain and SF-36 quality of life questionnaires before and 2 months after the treatment.

Results

Pain had improved significantly after 1, 2, and 6 months in both groups compared to the baseline. However, the amount of change was not different between the groups at any time interval. The results were the same for the Dallas pain scale and SF-36 quality of life questionnaire.

Conclusion

Adding biofeedback to pelvic floor muscle exercises did not lead to any further improvement in the management of chronic coccydynia. Further studies with larger sample sizes may reveal the effect of biofeedback more clearly.

Psychological Status and Quality of Life Associated with Radioactive Iodine Treatment of Patients with Differentiated Thyroid Cancer: Results of Hospital Anxiety and Depression Scale and Short-Form (36) Health Survey

Purpose:

The objective is to investigate psychological status and quality of life (QoL) using Hospital Anxiety and Depression Scale (HADS) and Short-Form (36) Health Survey (SF-36) questionnaires in patients with proven differentiated thyroid cancer (DTC) who are referred for radioactive iodine (RAI) ablation before, during, and after treatment.

Methods:

Of patients who underwent total thyroidectomy with a pathologically proven DTC (papillary and follicular types) referred for RAI treatment to our department in 2018, 150, in whom the diagnosis was newly established, were referred for the first course of RAI treatment and were consecutively enrolled in the study. The patients received an oral dose of radioiodine (3700 or 5550 MBq). For evaluation of anxiety, depression, and QoL, all patients are given two standard questionnaires, HADS, and SF-36 and are requested to answer them at four time points. First one was at 1 month before RAI, second was at the time of RAI treatment. Third and fourth ones were 1 week and 6 months later, respectively.

Results:

The mean age of patients was 39.17 (±12.95) years and 121 (80.7%) were female and 29 (19.3%) were male. Values of HADS and SF-36 scores at corresponding time points were significantly correlated using Pearson correlation (HADS and SF-36 scores at 1 month before RAI: r = −0.56, P < 0.001; at time of RAI: r = −0.71, P < 0.001; 6 months after RAI: r = 0.19, P = 0.021). Using paired-sample t-test, for HADS, except for difference between time points of 1 month before RAI and time of RAI, pairwise difference between scores of other time points was statistically significant after Bonferroni correction. For SF-36, pairwise difference between scores of all three time points was statistically significant. Interaction of age, gender, RAI dose, and thyroid-stimulating hormone level at the time of RAI on HADS and SF-36 scores did not show statistical significance.

Conclusion:

Trend in scores over several-months’ time discloses gradual improvement of QoL and merits close observation but limited psychiatric intervention.

Persian version of the brief Older People's Quality of Life questionnaire (OPQOL-brief): the evaluation of the psychometric properties

BACKGROUND AND OBJECTIVE

Quality of life (QoL) is a multi-dimensional concept and its assessment is one of important themes of care for older people. Assessing QoL in older people needs specific scales. The aim of this study was to culturally adapt and investigate the psychometric properties of the Persian version of brief Older People's Quality of Life questionnaire (OPQOL-brief) in an Iranian older population.

METHODS

This methodological cross-sectional study was conducted among 525 Persian-speaking older people (aged 60 and over), living in Isfahan, Iran. Translation of the OPQOL-brief questionnaire was performed using forward-backward method. Test-retest reliability was evaluated through Intra Class Correlation (ICC) coefficient and internal consistency by using Cronbach's α. Construct validity was investigated by using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and Latent class analysis (LCA). Criterion, convergent and discriminant validities were also assessed.

RESULTS

Persian version of the OPQOL-brief showed good test-retest reliability (ICC = 0.842, 95% CI = 0.73-0.91; P < 0.001). Persian OPQOL-brief scale demonstrated high internal consistency (Cronbach's α = 0.83). It showed good discriminant validity and differentiated old patients from healthy older individuals (P < 0.001). Construct validity based on EFA led to extraction of three dimensions ("socioeconomic", "emotional", and "physical" well-being) and the CFA confirmed the adequacy of extracted construct from EFA (CFI = 0.909, PCFI = 0.52, PNFI = 0.5, CMIN/DF = 3.012, and RMSEA = 0.08). LCA classified participants into three classes in terms of QoL level (low (16%), middle (67%), and high (17%)). Criterion validity and convergent validity revealed significant positive correlations between OPQOL-brief and physical and psychological dimensions of the SF-36.

CONCLUSION

The Persian version of the OPQOL-brief is a reliable and valid instrument for assessing QoL with applicability in a broad range of older Persian language population.

A web-based daily care training to improve the quality of life of mothers of children with cerebral palsy: A randomized controlled trial

BACKGROUND

Mothers of moderately to severely affected children with cerebral palsy (CP) have to spend a long time to take care of their children. This time-consuming responsibility affects their physical and psychosocial health. Therefore, mothers as caregivers are required to receive special training to take care of their children.

AIMS

The aim of this study was to evaluate the effectiveness of a developed web-based intervention for daily care training of children with CP on their mothers' quality of life (QOL), anxiety, depression, stress, and their musculoskeletal pain.

METHODS AND PROCEDURES

This study was a single blind randomized controlled trial. 91 mothers of children with CP with Gross Motor Function Classification System (GMFCS) levels III, IѴ, and Ѵ, who aged from 4 to 12 years were assigned to the intervention and control groups using block randomization. Mothers in the control group received their routine face to face occupational therapy intervention and mothers in the intervention group received 12 weeks web-based intervention. QOL, depression, anxiety, stress, and pain were measured before and after the intervention in both groups.

OUTCOMES AND RESULTS

The results of analysis of covariance showed that after controlling the mean score of pretest of pain, the mean score of post-tests in the intervention and control groups was significantly different (P < 0.05). The mean scores of physical health and total QOL scores of post-tests in the intervention group were significantly higher than the control group with controlling pretest scores.

CONCLUSIONS AND IMPLICATIONS

Designed web-based intervention affects the caregivers' QOL and pain significantly. This intervention can be used to provide daily care training for mothers of children with CP.

Psychometric properties of the Persian version of the Patient-Weighted Quality of Life in Epilepsy Inventory-10-P

BACKGROUND

The purpose of the study was to evaluate psychometric properties of the Persian version of the Patient-Weighted Quality of Life in Epilepsy Inventory-10-P (PV QOLIE-10-P).

METHODS

The Persian version was obtained from the original version by standard forward/backward translation. We assessed content validity, construct validity by factor analysis, internal consistency, test-retest reliabilities, criterion validity by calculating Pearson/Spearman correlation to the Persian version of the SF-36 inventory the Persian version of the 36-Item Short Form Health Survey (PV SF-36), and discriminant validity by calculating Pearson/Spearman correlation to demographic features and epilepsy-specific characteristics.

RESULTS

One hundred and fifty-five adult patients with epilepsy were enrolled in the study. The 10 items of PV QOLIE-10-P were grouped into two factors: epilepsy effects/role function scale (driving, work, social, memory, physical effect, and mental effect) and mental health scale (energy, depression, seizure worry, and overall quality of life). The Cronbach's alpha value was 0.859. Test-retest analysis revealed statistically significant correlations for total score and the scales (correlation coefficient for total score, epilepsy effects/role function, and mental health were 0.7, 0.66 and 0.7respectively). The Pearson correlation coefficient between total scores of the Persian version of QOLIE10-P and SF-36 was 0.822 (p < 0.001). The PV QOLIE-10-P was able to differentiate patients with marriage, education, job, seizure type, seizure frequency, and antiepileptic treatment.

CONCLUSION

The Persian version of QOLIE-10-P is a valid and reliable tool to assess the quality of life of patients with epilepsy in Iran.

Relation of health-related quality of life with abnormal weight: A cross-sectional study prior to the weight reduction intervention

Objective

Obesity is a major health issue that is well-documented association with morbidity and mortality. The aim of this study was to investigate the associations between health-related quality of life (HRQOL) and abnormal body mass index (BMI) levels.

Materials and Methods

This descriptive study assessed 134 healthy individuals with abnormal BMI aged 18-39 years, clustered into three weight categories. The Short-form (SF)-36 Questionnaire was used for measuring of HRQOL.

Results

Linear-regression analyses discovered the negative correlation between BMI and the general health element of HRQL, however, a positive relation to role emotional dimension. But BMI was not associated with other six dimensions, and also with physical and mental component summary and with total health quality of life.

Conclusion

BMI was an important detriment factor for the general health dimension of HRQL with regression analysis. The higher grade of abnormal BMI had a negative influence on general health and positive effect on the role emotional dimension of HRQOL.

Dietary inflammatory index is associated with pain intensity and some components of quality of life in patients with knee osteoarthritis

OBJECTIVES

We aim to measure dietary inflammatory index (DII) and its association with functional status, pain intensity and quality of life (QOL) in patients with knee osteoarthritis (KOA). Dietary information from 220 qualified patients with KOA was collected by a 168-item food frequency questionnaire. The functional status, pain intensity and QOL were evaluated by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire, Visual Analogue Scale (VAS) and SF36 questionnaire respectively.

RESULTS

Linear regression analysis showed that the DII was significantly associated with VAS (p = 0.040; β = 0.151), and physical function (p = 0.039; β = - 0.184), emotional wellbeing (p = 0.048; β = - 0.158) and pain (p = 0.020; β = 0.161) scales and physical health (p = 0.047; β = 0.110) subscale of QOL after adjusting for age, sex, body mass index, and physical activity. There was no significant differences concerning WOMAC across the DII tertiles with and without adjustment to probable confounders (Ptrend = 0.091 and 0.181, respectively). After adjustment, a significantly increased severe pain odds was observed in the highest tertile of DII score in comparison with the lowest tertile (OR tertile 3 vs. 1 = 1.55, 95% CI 1.04-2.31; Ptrend = 0.04).

The relationship between serum 25-hydroxy vitamin D and blood pressure and quality of life in overweight and obese patients with type 2 diabetes mellitus compared with healthy subjects

Background:

Vitamin D is one of the known lipoprotein hormones with metabolic properties. We aimed to determine the serum 25-hydroxy vitamin D concentration in overweight/obese subjects with diabetes mellitus type Ⅱ (DM Ⅱ) in association with systolic and diastolic blood pressure and quality of life compared with healthy participants.

Methods:

The current case-control study was carried out among 80 overweight/obese subjects with DM Ⅱ, and 77 healthy subjects matched by sex, age and body mass index (BMI). Serum 25-hydroxyvitamin D concentration was measured by ELISA method. In order to examine the quality of life, the Persian version of SF36 questionnaire was used.

Results:

There was significant difference between diabetic and healthy subjects considering serum 25-hydroxyvitamin D concentration (p=0.012). Serum 25-hydroxyvitamin D concentration was inversely correlated with diastolic blood pressure (p=0.02) and positively associated with physical function (p<0.001), social function (p<0.001) and general health (p<0.001) components of quality of life in diabetic subjects and physical health sub-scale (p=0.004) in all participants.

Conclusion:

Serum 25-hydroxyvitamin D concentration was significantly lower in diabetic subjects in comparison with healthy controls. There was a significant reverse relationship between serum concentrations of 25-hydroxyvitamin D with diastolic blood pressure and on the other hand, a significant positive relationship with physical function, social function and general health components and physical health subscale of quality of life in participants with DM Ⅱ.

Comparing the effects of anticipatory postural adjustments focused training and balance training on postural preparation, balance confidence and quality of life in elderly with history of a fall

BACKGROUND

Impairment of postural adjustments in elderly is associated with decreased functional mobility, balance confidence and quality of life.

AIMS

We studied the effects of anticipatory postural adjustments focused training on postural preparation, balance confidence and quality of life of the elderly.

METHODS

It was a single-blind randomized controlled trial. The sample included 60 males with history of falling (at least once in the past 6 months). They were matched and randomly assigned into three groups: perturbation, balance, and no training. The electrical activity of the muscles was measured by electromyography. The Activities-specific Balance Confidence (ABC) scale and the SF-36 questionnaire were used to assess balance confidence and quality of life, respectively. Repeated-measures ANOVA was used for data analysis (significant level 0.05).

RESULTS

The type of training had significant interaction effect on muscle latency (F_{(2, 46)} ≥ 71.06, P ≤ 0.001, η² ≥ 0.75). Compared to the other two groups, perturbation training group showed significantly more improvement in ABC scale (F_{(2, 46)} = 14.94, P ≤ 0.000, η² ≥ 0.39). It also significantly showed more improvement than no training group in all areas of SF-36 questionnaire, except for mental health (F_{(2, 46)} ≥ 6.56, P ≤ 0.03, η² ≥ 0.22).

CONCLUSIONS

Our findings support the use of perturbation training, as it reduced the probability of falling (by decreasing muscle latency and increasing posture preparation), improved the balance confidence for daily activities, and improved the quality of life.

Clinical and Functional Outcomes of Ulnar Lengthening in the Treatment of Masada Type I Forearm Deformities in Hereditary Multiple Osteochondromas

PURPOSE

Forearm deformity is common in hereditary multiple osteochondromas (HMO). The results of ulnar lengthening and osteochondroma excision are generally favorable, both clinically and radiographically. This study aimed to assess the clinical, radiographic, and functional results of forearm reconstruction in patients with Masada type I deformity (osteochondroma in the distal ulna with radial bowing, without radial head dislocation).

METHODS

A retrospective review was performed on patients with HMO who underwent surgical reconstruction for a Masada type I forearm deformity over a 10-year period. Eleven forearms in 10 patients underwent gradual ulnar lengthening with an external fixator. Age at the time of surgery was 5 to 12 years. Radiographic evaluation included ulnar shortening, radial articular angle, and carpal slip. Clinical evaluation included range of motion of the elbow and wrist. Functional outcomes were evaluated with the Disabilities of the Arm, Shoulder, and Hand questionnaire and the Short Form-36 survey.

RESULTS

At an average follow-up of 37.5 months, significant improvement was observed in ulnar shortening, the radial articular angle, and carpal slip. Preoperative average Disabilities of the Arm, Shoulder, and Hand score of 24.2 improved to 17.3. Significant improvement was observed in 3 measures of the Short Form-36 survey: general health, social functioning, and health change.

CONCLUSIONS

In agreement with the literature, surgical reconstruction yielded favorable clinical and radiographic results in Masada type I forearm deformities. The main functional improvement was observed in scales of mental health. The baseline physical impairment was minimal in the absence of radial head dislocation, but although it improved with treatment, it was not necessarily clinically relevant. This study can assist surgeons and families in setting realistic goals and expectations for surgery. There may also be additional long-term benefits to forearm lengthening in HMO, including prevention of radial head dislocation, improved range of motion, and better cosmesis, which future research may help to clarify.

Effects of Aquatic Exercise on Dimensions of Quality of Life and Blood Indicators in Patients with Beta-Thalassemia Major

BACKGROUND

Thalassemia is considered as a group of genetic blood disorders, characterized by anemia. The present research aimed at evaluating the effects of aquatic exercise on quality of life and blood indices in patients with beta-thalassemia major.

METHODS

A clinical trial study involving 40 patients with thalassemia major, divided into two groups: experimental and control. The tools used to collect the data included demographic information questionnaire, blood indicators questionnaire, and SF-36 quality of life questionnaire. The experimental group performed exercise in water three times per week for 8 weeks in the pool after obtaining the consent. In this research, the quality of life questionnaire was filled out 24 h before the intervention, 24 h after the last session of the exercise program, and 2 months after the end of the exercise program.

RESULTS

CONCLUSIONS

The use of a regular exercise program combined with drug therapy and blood transfusion can be useful in the treatment of beta-thalassemia patients.

The Effect of Positive Thinking Training on Different Dimensions of Quality of Life of Hemodialysis Patients: A Randomized Controlled Clinical Trial

Background: Nowadays, the quality of life of hemodialysis patients has decreased, which doubled the need for educational interventions. Objectives: The current study investigated the effect of positive thinking training on different dimensions of quality of life of hemodialysis patients. Methods: This is a controlled clinical trial study conducted on 70 hemodialysis patients in Fasa, Fars province, in 2019. The patients were selected using the simple sampling method. Then, they were divided into two groups of intervention (n = 35) and control (n = 35). After obtaining informed consent, the researchers asked the participants to complete the SF-36 Quality of Life Questionnaire. The intervention group was trained positive thinking skills in 8 workshop sessions; each lasted for 90 minutes. Data were analyzed using SPSS version 20. To analyze the data, statistical tests such as chi-square, Kolmogorov-Smirnov, independent, and t-test were used. Results: The mean and standard deviation of the patients’ quality of life in the intervention group increased from 35.95 ± 10.07 to 55.98 ± 11.71 (P < 0.001). The changes in patients’ quality of life before and after the intervention were also assessed in 8 dimensions, which showed that the quality of life of the patients did not change significantly in terms of physical function (P = 0.42) and physical pain (P = 0.62), but for other dimensions, it was significantly increased (P < 0.001). Conclusions: Positive thinking training improved the quality of life of hemodialysis patients, particularly in the dimensions of the emotional role, emotional health, energy and vitality, social performance, and general health is recommended.

Comparison of SF-36 and WHOQoL-BREF in Measuring Quality of Life in Patients with Type 2 Diabetes

Objective

This study aimed to compare the quality of life (QoL) in patients with type 2 diabetes using two WHOQoL -BREF and SF-36 questionnaires in Iran.

Patients and Methods

In this cross-sectional study, 1847 patients with type 2 diabetes were recruited from rural health-care centers affiliated to Neyshabur County (Iran) in 2012. In addition to demographic information, two questionnaires WHOQoL-BREF and SF-36 questionnaires were used for data collection. Cronbach’s alpha coefficient was used for scale reliability. We conducted an exploratory factor analysis for the investigation of construct validity. Convergent and discriminant validity were analyzed using Spearman correlation coefficient. To determine the relationships between the eight domains of SF-36 and four domains of the WHOQoL-BREF, structural equation modelling was performed.

Results

Cronbach’s alpha coefficients were acceptable for all domains of both WHOQoL-BREF (0.69–0.86) and SF-36 (0.63 −0.92) questionnaires. The principal component analysis showed two separate factors: one for all domains of SF-36 and another for all domains of WHOQoL-BREF. Spearman correlation coefficients of both instruments were partly to strongly correlated with most domains (r ≥0.40). Correlations for domains with similar constructs were stronger than those measuring varied constructs. Structural equation modelling recommended approximately moderate relationships among the SF-36 and WHOQoL-BREF domains.

Conclusion

Our study suggests that SF-36 and WHOQoL-BREF are reliable instruments for clinical and research uses, respectably. However, results of the goodness of fit showed that the WHOQoL-BREF was fitted well. Also, the WHOQoL-BREF can be considered more suitable for the study population.

Validity and reliability: the Iranian version of Lawton IADL in elderly community dwellers

Purpose

Normal aging changes, acute and chronic illness, and the long stay in the hospital made the decline in elderly physical and mental abilities in non-instrumental and Instrumental Activities Daily Livings (IADL). This paper aims to determine the validity and reliability of Lawton IADL in the Iranian elderly community relevancy to physical, mental and cognitive measurements.

Design/methodology/approach

A cross-sectional study with 422 participants, age 60 years old and over selected by face-to-face interviewing from the geriatric clinic, Tehran medical university from January to June 2019.

Findings

Of 422 participants referring to outpatient clinics the majority were male (62.8%); with an average of 66.9 ± 5.95 years old. Reliability was significantly high (Cronbach’s alpha = 0.96, p < 0.001). There was a significant relationship between IADL with Short-Form Health Survey36-Mental Component Score (SF36-MCS), with p < 0.01. Reliability was significantly high (Cronbach’s alpha = 0.96, p < 0.001). In the factor analysis with eigenvalues more than one, two components were found; that the first factor named as observational daily activities, whereas the second factor named “advanced daily activities”.

Research limitations/implications

The limitation of this study was the low number of similar studies to compare the results and the stronger discussion.

Originality/value

Determining IADL's dependency in the community elderly is important to maintain their self-care manages. More studies are needed to manifest the relationship between mental health and IADL's independence. Therefore, validation in different settings is important in planning for the geriatrics team.

Efficacy of low-fat milk and yogurt fortified with encapsulated vitamin D3 on improvement in symptoms of insomnia and quality of life: Evidence from the SUVINA trial

INTRODUCTION

Sleep disorders are a common condition globally. Vitamin D receptors are present on cells in several regions of the brain. It is possible that vitamin D status may affect brain function, including sleep patterns. We aimed to evaluate the 1,500 IU of Nano-encapsulated vitamin D fortified in dairy products on the symptoms of insomnia and associated improvement of quality of life.

METHODS

A case series was undertaken as part of the Survey of ultraviolent intake by nutritional approach project. Subjects enrolled among adults with abdominal obesity. Twenty-nine subjects with insomnia were selected according to the results of Insomnia Severity Index questionnaire and quality of life using a Short Form Health Survey (SF-36) questionnaire. Subjects were allocated to four groups: low-fat milk fortified by 1,500 IU vitamin D3 (n = 8), simple milk (n = 8), low-fat yogurt fortified by 1,500 IU vitamin D3 (n = 7), and simple yogurt (n = 6) and were treated for 10 weeks.

RESULTS

The insomnia score improved after the intervention in the group receiving vitamin D fortified milk compared to group receiving unfortified milk (p < .001). There were no significant differences between the two groups taking yogurt (fortified vs. unfortified). Comparison of quality of life scores between baseline and after intervention indicated significant improvements in both fortified and simple milk groups (p = .002 and p = .03, respectively); but no differences were found in the groups taking yogurt.

CONCLUSION

Fortified low-fat milk containing 1,500 IU vitamin D3 can improve insomnia symptoms and subsequently quality of life.Trial registration number: IRCT20101130005280N27, www.IRCT.ir.

Effect of self-care counselling on depression and anxiety in women with endometriosis: a randomized controlled trial

BACKGROUND

Considering the prevalence of endometriosis and consequent depression and anxiety as well as the resultant effects on the body, mind, and quality of life of patients, this study aimed to determine the effects of self-care counselling on depression and anxiety (primary outcome) and on quality of life (secondary outcome) among women with endometriosis.

METHOD

This randomized controlled clinical trial was conducted on 76 women with endometriosis who were treated at Al-Zahra Teaching and Treatment Center of Tabriz within the 2015-2019 period. The random blocking method was employed to divide the patients into intervention (counselling) and control groups. In the intervention group, seven self-care group counselling sessions were held on a weekly basis. The control group received routine care. A sociodemographic questionnaire, Beck Depression Inventory, Spielberger State-Trait Anxiety Inventory (STAI) and the SF-36 Quality of Life Questionnaire were completed by the researcher through an interview before and 4 weeks after the intervention.

RESULTS

There was no significant difference between the intervention and control groups in terms of sociodemographic characteristics (p > 0.05). After the intervention, the mean scores of state anxiety (mean difference: - 0.12, 95% confidence interval: - 9.6 to - 14.4, p < 0.001) and trait anxiety (mean difference: - 10.9: 95% confidence interval: - 9.1 to - 12.7, p = 0.001) were significantly lower in the counselling group than those of the control group. The mean score of depression was lower in the counselling group than in the control group; however, it was not significant (p = 0/565). The mean score of quality of life for physical health (mean difference = 17.2, 95% confidence interval: 13.8 to 20.5, p < 0.001) and for mental health (mean difference = 12.0, 95% confidence interval: 9.0 to 14.9, p < 0.001) were significantly higher in the counselling group than in the control group.

CONCLUSION

Self-care counselling affects the anxiety and quality of life of women with endometriosis. Therefore, in addition to other therapies, this method is proposed to improve quality of life and mental health of patients with endometriosis.

Predictors of Fear of Falling among Iranian Older Adults with Hip Fracture and Controls

OBJECTIVES

To investigate predictors of fear of falling (FOF) among older people with or without hip fracture.

METHODS

The FOF was assessed by the Visual Analogue Scale (VAS-FOF), anxiety and depression by the Hospital Anxiety and Depression Scale (HADS). The modified Berg Balance Scale (mBBS) to evaluate functional balance was used. All people were asked to complete the dizziness Handicap Inventory (DHI) and the 36-item Short Form Health Survey (SF-36) for evaluating quality of life.

RESULTS

Eighty-eight older adults (44 cases; 44 controls) took part in this study. The case group had received surgical intervention for femoral neck or trochanteric fracture resulting from a fall. The results showed significantly more intensity of FOF in hip fracture patients than controls (p < .001). The FOF was significantly correlated with anxiety, DHI, mBBS, and SF-36. The results of the multiple linear regression showed that four predictors explained about 44% of the variance of the FOF. It was found that mBBS and DHI significantly predicted FOF (p < .001 and < .001, respectively).

CONCLUSIONS

The hip fracture patients had a high degree of the fear of falling, low quality of life and low functional capacity. The mBBS and DHI were significant predictors of the FOF in older adults.

CLINICAL IMPLICATIONS

It may be useful to employ an inter-disciplinary approach to addressing fear of falling to best understand physiological and psychological contributions.

Validation and responsiveness of the Persian version of HeartQoL questionnaire in cardiac rehabilitation after coronary artery bypass grafting: An observational study

BACKGROUND

Decision making and the quality of care provided for chronic diseases have been shown to improve through patient participation. The HeartQoL questionnaire is a core health-related quality of life (HRQOL) tool specifically designed for individuals with ischemic heart disease (IHD) who have undergone interventions such as cardiac rehabilitation (CR).

METHODS

In this observational and multicenter study, 150 patients were recruited. The participants completed the HeartQoL, MacNew Heart Disease Questionnaire, and Short Form Health Survey (SF-36) on entering CR for validity assessment. The HeartQoL along with a Global Rating of Change (GRoC) scale (for responsiveness measurement) were completed by 100 participants 3 months later.

RESULTS

The mean age of all participants in validity assessment was 61.87 ± 8.13 years. Cronbach's alphas of the total scales ranged from 0.70 to 0.81 and of the subscales from 0.70 to 0.82. The Pearson correlation coefficient was used to determine construct validity; similar constructs were confirmed with correlation coefficients ranging from 0.50 to 0.69 and dissimilar constructs with correlation coefficients ranging from 0.28 to 0.29 (P < 0.010). The assessment of the responsiveness of the questionnaire indicated that the area under curve (AUC) was greater than 0.70 (range: 0.74 to 0.91) and the optimal cut-off point was 0.65.

CONCLUSION

The Persian version of the HeartQoL questionnaire demonstrated satisfactory psychometric properties in the sample of participants admitted to CR after coronary artery bypass grafting (CABG). The present study results showed that the HRQOL can be used by clinicians and researchers in conjunction with other outcome measures to gain additional information about symptoms relevant to HRQOL in patients referred to CR and to evaluate change over time.
