Review
Virtual Reality (VR) has been gaining increasing attention as a potential ecological and effective intervention system for treating Mild Cognitive Impairment (MCI). However, it remains unclear the efficacy and effectiveness of VR-based cognitive rehabilitation therapy (VR-CRT) in comparison with cognitive rehabilitation therapy (CRT). Consequently, a systematic review on Pubmed, Scopus, PsycInfo, and Web Of Science was conducted to assess the state of the art of the literature published between 2003 and April 2023. Only articles that adopted CRT as control group and that included some measure of at least one domain among overall cognitive function, executive function and functional status were included. Participants needed to be older adults aged 65 or over with a diagnosis of MCI. The risk of bias and the quality of evidence were assessed using the Version 2 of the Cochrane risk-of-bias tool for randomized trials. Initially, 6503 records were considered and screened after removing duplicates (n = 1321). Subsequently, 81 full texts were assessed for eligibility. Four articles met the inclusion criteria but 2 of them were merged as they were describing different outcomes of the same research project. Consequently, 3 overall studies with a total of 130 participants were included in the final analysis. Due to the high heterogeneity in the methodology and outcome measures employed, it was not possible to conduct a meta-analysis. Included studies used semi-immersive (k = 2) and full-immersive (k = 1) VR systems in their research. Two articles evaluated overall cognitive function through the MoCA together with specific tests for executive functions (n = 69), while one study adopted a comprehensive neuropsychological battery to evaluate both cognitive function and executive function (n = 61). Finally, one study evaluated functional status through instrumental activities of daily living (n = 34). A However, the limited number of studies, the small sample size, and the potential issues with the quality and methodology of these studies that emerged from the risk of bias assessment may raise doubts about the reliability of their results. Nevertheless, although scarce, results of the present review suggest that VR-CRT may be paramount in treating MCI for its additional ecological and adaptive advantages, as all of the studies highlighted that it was at least as effective as conventional CRT for all the outcome measures. Therefore, more rigorous research that compares VR-CRT and CRT is needed to understand the degree to which VR-CRT is effective with older adults with MCI and the potential role of immersion to influence its efficacy. Indeed, these preliminary findings highlight the need for the development of standardized VR protocols, as the integration of such technology into clinical practice may help improve the quality of life and cognitive outcomes for this growing demographic.

Impact of comorbidities on health status measured using the Kansas City Cardiomyopathy Questionnaire in patients with heart failure with reduced and preserved ejection fraction.
AIM
Patients with heart failure (HF) often suffer from a range of comorbidities, which may affect their health status. The aim of this study was to assess the impact of different comorbidities on health status in patients with HF and reduced (HFrEF) and preserved ejection fraction (HFpEF).
METHODS AND RESULTS
Using individual patient data from HFrEF (ATMOSPHERE, PARADIGM-HF, DAPA-HF) and HFpEF (TOPCAT, PARAGON-HF) trials, we examined the Kansas City Cardiomyopathy Questionnaire (KCCQ) domain scores and overall summary score (KCCQ-OSS) across a range of cardiorespiratory (angina, atrial fibrillation [AF], stroke, chronic obstructive pulmonary disease [COPD]) and other comorbidities (obesity, diabetes, chronic kidney disease [CKD], anaemia). Of patients with HFrEF (n = 20 159), 36.2% had AF, 33.9% CKD, 33.9% diabetes, 31.4% obesity, 25.5% angina, 12.2% COPD, 8.4% stroke, and 4.4% anaemia; the corresponding proportions in HFpEF (n = 6563) were: 54.0% AF, 48.7% CKD, 43.4% diabetes, 53.3% obesity, 28.6% angina, 14.7% COPD, 10.2% stroke, and 6.5% anaemia. HFpEF patients had lower KCCQ domain scores and KCCQ-OSS (67.8 vs. 71.3) than HFrEF patients. Physical limitations, social limitations and quality of life domains were reduced more than symptom frequency and symptom burden domains. In both HFrEF and HFpEF, COPD, angina, anaemia, and obesity were associated with the lowest scores. An increasing number of comorbidities was associated with decreasing scores (e.g. KCCQ-OSS 0 vs. ≥4 comorbidities: HFrEF 76.8 vs. 66.4; HFpEF 73.7 vs. 65.2).
CONCLUSIONS
Cardiac and non-cardiac comorbidities are common in both HFrEF and HFpEF patients and most are associated with reductions in health status although the impact varied among comorbidities, by the number of comorbidities, and by HF phenotype. Treating/correcting comorbidity is a therapeutic approach that may improve the health status of patients with HF.

Randomized Controlled Trial
Effect of dapagliflozin on health status and quality of life across the spectrum of ejection fraction: Participant-level pooled analysis from the DAPA-HF and DELIVER trials.
AIMS
Patients with heart failure experience a high burden of symptoms and physical limitations, and poor quality of life. Dapagliflozin reduces heart failure hospitalization and cardiovascular death in patients with reduced, mildly reduced, and preserved ejection fractions. We examined the effects of dapagliflozin on health status, measured by the Kansas City Cardiomyopathy Questionnaire (KCCQ), across the full spectrum of left ventricular ejection fraction (LVEF).
METHODS AND RESULTS
Participant-level data were pooled from the DAPA-HF and DELIVER trials. Both trials were randomized, global, double-blind, placebo-controlled trials of patients with symptomatic heart failure and elevated natriuretic peptides. DAPA-HF and DELIVER included patients with LVEF ≤40% and LVEF >40%, respectively. KCCQ was evaluated at randomization and at 4 and 8 months post-randomization; the effect of dapagliflozin versus placebo on KCCQ total symptom score (TSS) was a pre-specified secondary outcome in both trials. Interaction testing was performed to assess potential heterogeneity in the effects of dapagliflozin versus placebo on KCCQ-TSS, clinical summary score (CSS), overall summary score (OSS), and physical limitation score (PLS), by continuous LVEF using restricted cubic splines. Responder analyses examining the proportion of patients with meaningful deterioration (≥5 point decline) and meaningful improvements (≥5 point increase) in KCCQ-TSS was assessed across LVEF categories. Of 11 007 randomized participants, 10 238 (93%) had full data on KCCQ-TSS at randomization. Benefits of dapagliflozin versus placebo on KCCQ-TSS, -CSS, -OSS, -PLS, at 8 months were consistent across the full range of LVEF (p = 0.19, 0.10, 0.12, 0.10, respectively). In responder analyses, fewer dapagliflozin- versus placebo-treated patients had clinically meaningful deteriorations in KCCQ-TSS (overall: 21% vs. 23%; LVEF ≤40%: 21% vs. 29%; LVEF 41-60%: 21% vs. 26%; LVEF >60%: 22% vs. 27%). A greater proportion of patients randomized to dapagliflozin experienced at least small improvements in KCCQ-TSS (overall: 50% vs. 45%; LVEF ≤40%: 48% vs. 41%; LVEF 41-60%: 51% vs. 49%; LVEF >60%: 53% vs. 45%). The effects of dapagliflozin versus placebo on clinically meaningful deteriorations and improvements in health status by KCCQ-TSS were consistent across the full spectrum of LVEF assessed continuously (p = 0.20 and 0.64, respectively). Across the LVEF spectrum, the number needed to treat to affect ≥5 point improvement in health status assessed by KCCQ-TSS was 20. Health status declines preceding a HF hospitalization by ∼10 points were observed in both trials, evident up to 3 months prior to hospitalization.
CONCLUSIONS
In participant-level pooled analyses of DAPA-HF and DELIVER, dapagliflozin improved all key domains of health status across the full range of LVEF. Clinically meaningful improvements in health status were also observed consistently across LVEF, including in those with LVEF >60%.

Observational Study
Increase in the prevalence of hysterectomy among low-and middle-income countries (LMICs) such as India has become a significant concern. Reports based on either a particular group or region show an increasing trend in hysterectomy, but there is a dearth of national-level data in this domain. Hence, there seems to be an urgent need to garner evidence on the prevalence and determinants of hysterectomy, which could pave the way for future programs and policies. We aimed to estimate the prevalence of hysterectomy and assess its determinants using a nationally representative sample. An observational analysis was conducted using data from Longitudinal Aging Study in India (LASI), 2017-2018. 38,154 women aged > 18 years were included. A multivariable logistic regression, presented as an adjusted odds ratio (AOR) with a 95% confidence interval (CI), was used to predict the association between various socio-demographic characteristics and hysterectomy. A separate multivariable logistic regression model was executed to determine the association between selected non-communicable diseases (NCDs) and hysterectomy. Survey weights compensated the complex study design. The overall prevalence of hysterectomy was around 11.35%. Excessive menstrual bleeding followed by fibroids emerged as the leading causes of hysterectomy. The various determinants of hysterectomy were urban residents [AOR: 1.54 (1.21-1.96)], other backward class [AOR: 2.19 (1.72-2.78], working women [AOR: 1.19(1-1.42)] and the most affluent (rich) group [AOR: 2.06 (1.62-2.63)]. Hysterectomy was associated with cancer [AOR: 4.83 (2.51-9.29)], diabetes [AOR: 1.79 (1.25-2.57)], hypertension [AOR: 1.48 (1.27-1.71)] and joint diseases [AOR: 1.43 (1.09-1.88)]. Hysterectomy is considerably prevalent in India, which cannot be overlooked. Health promotion regarding hysterectomy and its implications is needed especially among urban residents, affluent groups and those with a higher body mass index. Health programmes aimed at women should follow a life course approach by prioritizing health and overall well-being even after reproductive years.

BACKGROUND
Physical end emotional changes during pregnancy may not only affect pregnant womens' quality of life, but also how instruments assessing quality of life perform in such populations. To date, there is insufficient evidence on psychometric properties for both generic and condition-specific instruments measuring quality of life during pregnancy. The aim of this study was thus to examine the structural validity, internal consistency, and construct validity of the WHOQOL-BREF in a sample of pregnant women.
METHODS
A convenience sample of 1015 pregnant women in Sweden completed the WHOQOL-BREF online. We examined the psychometric properties of the instrument using principal component analysis (PCA), confirmatory factor analysis (CFA), Cronbach's alpha, item-domain correlations, correlations with overall QOL and general health, and multiple linear regression with items on overall QOL and general health as outcomes.
RESULTS
Principal Component Analysis in a random subsample (n = 502) supported a four-factor model, encompassing the domains physical, psychological, social and environmental quality of life, but with four of the items originally in the environmental domain relocated to the other domains. The proposed domain structure showed good fit in confirmatory factor analysis in the other random subsample (n = 513). The physical and psychological domains showed good internal consistency (Cronbach's alpha = 0.885 and 0.826 respectively), while the social and environmental domains were weaker in this regard. All domains showed significant positive correlations with items on overall QOL and general health. The physical and psychological domains were the most evident predictors in the regression models.
CONCLUSIONS
We find the Swedish version of the WHOQOL-BREF to have good psychometric properties to be used in samples of pregnant women, and propose an alternative domain structure that might be even more useful for assessing quality of life during pregnancy. The physical and psychological domains showed good internal consistency and construct validity.

PURPOSE
Many generic patient-reported instruments are available for the measurement of health outcomes, including EQ-5D-5L, and the Patient-Reported Outcome Measurement Information System (PROMIS). Assessing their measurement characteristics informs users about the consistency between, and limits of, evidence produced. The aim was to assess the measurement relationship between the EQ-5D-5L descriptive system and value sets, the PROMIS-29 and PROPr (PROMIS value set).
METHODS
Data were extracted from a cross-sectional survey administering measures of quality of life online in Australia. Descriptive analysis, agreement and construct validity assessment methods were used to compare instruments at the item, domain and value set level.
RESULTS
In total, 794 Australians completed the survey. Convergent validity analysis found that similar dimensions across instruments were highly correlated (> 0.50), but the PROMIS-29 assesses additional health concepts not explicitly covered by EQ-5D (sleep and fatigue). Known-group assessment found that EQ-5D-5L and PROPr were able to detect those with and without a condition (ES range 0.78-0.83) but PROPr could more precisely detect differing levels of self-reported health. Both instruments were sensitive to differences in levels of pain.
DISCUSSION
There is some consistency in what the EQ-5D-5L, PROMIS-29 and PROPr measure. Differences between value set characteristics can be linked to differences what is measured and the valuation approaches used. This has implications for the use of each in assessing health outcomes, and the results can inform decisions about which instrument should be used in which context.

The purpose of the present study is to develop and validate the hypertension scale of the Quality of Life Instruments (QoL) for Chronic Diseases system, QLICD-HY (V2.0). The QLICD-HY (V2.0) was developed via a programmed decision method with several focus groups, nominal discussions and pilot testing. The data was collected from 370 hypertensive inpatients and measured their QoL three times before and after treatment. Using correlation, factor analyses, as well as t-tests, the psychometric properties of the scale were assessed with regard to validity, reliability and responsiveness. Correlation and factor analysis supported good construct validity and criterion-related validity when using Short Form 36 as a criterion. Test-retest reliability coefficients for the overall scale score and all domains, with the exception of the psychological and social domain (0.77, 0.78), were greater than 0.80, with a range of 0.77-0.92. The internal consistency for all domains was higher than 0.70. With the exception of the psychological domain and social domain, the overall score and scores for the majority of aspects within each domain underwent statistically significant changes (t-tests) after the treatment. The QLICD-HY (V2.0) has good validity, reliability and responsiveness and can be used as a QoL measure for hypertensive patients.

Observational Study
AIMS
To evaluate the psychometric properties of a newly designed questionnaire, the 40-item Glaucoma Visual Functioning Questionnaire (GVFQ-40), in a Chinese sample to capture the visual ability of patients with glaucomatous vision impairment in five domains.
METHODS
Eighty-four glaucoma suspects (controls) and 270 glaucoma patients were recruited from the Glaucoma Clinic at Zhongshan Ophthalmic Centre in this cross-sectional, observational study. All subjects completed two questionnaires during routine clinical visits: the GVFQ-40 and the validated National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25). The discriminant, criterion-related and construct validity of the GVFQ-40 were assessed. A subset of subjects completed the GVFQ-40 twice, with an interval of 7-21 days, to determine test-retest reliability.
RESULTS
Domain-specific and total GVFQ-40 scores were significantly higher (worse visual ability) in glaucoma patients than in controls (all p<0.001). All pairwise subgroup comparisons were statistically significant except for the 'mobility' domain comparison between the mild visual field loss and control groups (p=0.189). Significant differences between these two groups were observed in only 2 of the 12 dimensions on the NEI VFQ-25. The GVFQ-40 results demonstrated strong correlations with better-eye mean deviation and Visual Field Index (glaucoma severity measures). Exploratory factor analysis tended to confirm a three-domain structure. Test-retest intraclass correlation coefficients were higher than 0.927 for domain-specific and total GVFQ-40 scores.
CONCLUSIONS
The GVFQ-40 possesses good validity and reliability. It can be used to evaluate the impact of glaucomatous damage on visual ability and has potential in the evaluation of intervention efficacy.

INTRODUCTION
Health literacy (HL) is both a direct determinant and a mediator of health outcomes. Research on the prevalence and determinants of HL in terms of its functional, communicative, and critical domains is scarce in the state of Qatar and its surrounding regions. Thus, this study aims to fill the knowledge gap in this area, estimate the levels of functional, communicative, and critical health literacy among the general adult population, and identify its determinants in the state of Qatar.
METHODS
An analytical cross-sectional study with a disproportionate stratified random sampling technique was conducted in 2022. A representative sample of phone numbers was obtained from the Cerner database at Hamad Medical Corporation and approached via well-trained data collectors. A socio-demographic and health-relevant factor questionnaire and the validated All Aspects of Health Literacy scale (AAHLS) were used to collect the data on functional, communicative, and critical HL and their determinants. Descriptive analysis, independent sample -test, ANOVA, and linear regression were used and yielded the outcomes on HL levels as low, adequate, and high in percentages and the HL determinants.
RESULTS
A total of 770 participants were included. The study found that 41.5%, 29.3%, and 29.2% of them have adequate, high, and low overall HL levels consecutively. People who participated in the study are older adult, are of Arabic ethnicity, are of Qatari ethnicity, have a lower level of education, have close relatives with a lower level of education, have a lower income, are non-migrants, are not living within a family, sought medical care within the last week, and who do not know if they have a chronic disease or do not have lower overall HL levels compared to the other groups. After linear regression analysis, only the participant's level of education and "last time sought medical care within last week" variable predict the overall HL score.
CONCLUSION
Almost half of Qatar's adult population has an adequate HL level, comparable to the HL levels in other regions, despite the limitation in comparison due to variation in context and the HL measurement tools used. The possible determinants are amenable factors to focus on while designing HL interventions and providing healthcare.

Review
Multiple sclerosis (MS) is a chronic inflammatory and demyelinating autoimmune disease. MS patients deal with motor and sensory impairments, visual disabilities, cognitive disorders, and speech and language deficits. The study aimed to record, enhance, update, and delve into our present comprehension of speech deficits observed in patients with MS and the methodology (assessment tools) studies followed. The method used was a search of the literature through the databases for May 2015 until June 2022. The reviewed studies offer insight into speech impairments most exhibited by MS patients. Patients with MS face numerous communication changes concerning the phonation system (changes observed concerning speech rate, long pause duration) and lower volume. Moreover, the articulation system was affected by the lack of muscle synchronization and inaccurate pronunciations, mainly of vowels. Finally, there are changes regarding prosody (MS patients exhibited monotonous speech). Findings indicated that MS patients experience communication changes across various domains. Based on the reviewed studies, we concluded that the speech system of MS patients is impaired to some extent, and the patients face many changes that impact their conversational ability and the production of slower and inaccurate speech. These changes can affect MS patients' quality of life.
