Overactive bladder symptom severity, bother, help-seeking behavior, and quality of life in patients with type 2 diabetes: a path analysis

An analysis of urodynamic parameters in diabetic and nondiabetic women

OBJECTIVES

Diabetes is highly prevalent worldwide, with an estimated 536 million living with diabetes in 2021, and that number projected to increase to 783 million by 2045. Diabetic bladder dysfunction is thought to affect up to 60%-90% of individuals with diabetes and can significantly impact quality of life. Despite the prevalence of diabetic bladder dysfunction, the exact pathophysiological mechanism, and resulting clinical presentation, remains debated. Our objective was to compare urodynamic parameters between diabetic and nondiabetic women, assessing the impact of various markers of diabetes severity on bladder function.

METHODS

A retrospective chart review was conducted on female patients aged 18 and above who underwent urodynamic studies at a single tertiary care university hospital system from 2014 to 2020. Patients were categorized based on diabetes status, and diabetes severity including duration of disease, hemoglobin A1c levels, insulin dependence, and markers of end-organ dysfunction. Urodynamic variables, including compliance, bladder voided efficiency, bladder contractility index, postvoid residual, maximum flow rate, capacity, voided volume, and detrusor overactivity, were assessed by two independent reviewers. Statistical analyses were performed to assess the impact of diabetes and diabetic severity on urodynamic parameters.

RESULTS

A total of 652 female patients were included in the study, of which, 152 (23.3%) had diabetes, with an average duration of diagnosis of 82.3 months. Diabetic women were older and had higher body mass index compared to nondiabetic women. Diabetic retinopathy and neuropathy were present in 18% and 54.6% of diabetic patients, respectively. Significant differences in urodynamic parameters were observed between diabetic and nondiabetic women, with diabetic women showing higher rates of detrusor overactivity (p = 0.01), particularly associated with increasing BMI (p = 0.03). However, classic markers of diabetes severity including duration, as well as markers of end-organ damage, showed mixed associations with urodynamic changes.

CONCLUSIONS

Despite the prevalence of diabetic bladder dysfunction and its impact on patient quality of life, the exact mechanisms and clinical presentation remain elusive. Our study highlights the significant differences in urodynamic parameters between diabetic and nondiabetic women, emphasizing the need for further research into the relationship between diabetes and diabetic bladder dysfunction.

Quality of life and thalassemia in India: A scoping review

In recent years, a multitude of studies have been conducted to investigate the assessment of quality of life (QoL) among individuals affected by thalassemia. This scoping review aimed to examine the existing knowledge regarding the QoL and its associated factors among individuals with thalassemia in India. Databases, such as PubMed, SCOPUS, Web of Science, and the Preferred Reporting Items for Systematic Review and Meta-Analysis Extension for Scoping Reviews (PRISMA-ScR) guidelines, were searched. A total of nine articles were included in the review. The included studies mainly investigated children. The Pediatric Quality of Life Inventory (PedsQL) is the most common instrument used most often. Overall, the research findings indicate that individuals who underwent blood transfusion exhibited a lower QoL than those who did not receive blood transfusion. Additionally, it was observed that children diagnosed with thalassemia reported a lower QoL than adults. Nevertheless, the studies exhibited notable methodological deficiencies that constrained the validity and generalizability of the results. Hence, it is imperative to undertake comprehensive QoL research encompassing all regions of India and various thalassemia populations within the country to bridge this evidentiary void.

Social Support, Health Behaviors, Self-Esteem, and Successful Aging in a Sub-Saharan African Sample of Older Adults: Test of a Sequential Mediation Model

Background and Objectives

Previous research demonstrates that social support facilitates successful aging across all cultures. However, the factors that potentially mediate the link between social support and successful aging remain unclear. This study examined whether a healthy lifestyle and self-esteem mediate the association between social support and successful aging. It was hypothesized that the relationship between social support (family, friends, and significant other) and successful aging would be serially mediated by both healthy lifestyle and self-esteem.

Research Design and Methods

Participants were 479 Nigerian retirees (53.4% female) aged 60 to 90 years (Mage = 64.81, SD = 6.86). They provided information on relevant demographic variables and completed the following measures: Fantastic Lifestyle Checklist (Fitness Appraisal), Rosenberg Self-esteem Scale, Multidimensional Scale of Perceived Social Support Scale, and Successful Aging Inventory. Three separate regression models (family, friends, and significant other dimensions of social support) were conducted using the Hayes PROCESS macro for SPSS with 5,000 bootstrap estimates.

Results

Controlling for age and sex, family support, significant other support, friends support, healthy lifestyle, and self-esteem were directly associated with successful aging. The association between family support and successful aging was mediated by healthy lifestyle; and this was also seen for friends' support and significant other support. The sequential path from social support to successful aging through healthy lifestyle, and then via improved self-esteem, was significant for family support and significant other support, but not friends support.

Discussion and Implications

Findings suggest that middle-aged to older adults who have strong support from their families and significant others may be more likely to engage in healthy behaviors and, in turn, experience higher levels of self-esteem, thereby aging well.

The impact of diabetes on overactive bladder presentations and associations with health-seeking behavior in China, South Korea, and Taiwan: Results from a cross-sectional, population-based study

BACKGROUND

This study aimed to explore the impact of diabetes on overactive bladder (OAB) presentations and related predictors of healthcare-seeking behavior among adults aged ≥ 40 years in China, Taiwan, and South Korea.

METHODS

An internet-based survey was conducted to assess the prevalence of diabetes, OAB presentations, and self-perceived urinary symptoms by a multi-national sample of 8284 individuals who completed the survey between June 2, 2015 and July 31, 2015. Independent associations with health-seeking behavior for urinary symptoms were estimated with odds ratio (OR) with 95% confidence interval (95% CI) using multivariate logistic regression.

RESULTS

Diabetes was reported in 13.6% of participants and OAB was 20.8%. Diabetic participants were older than non-diabetic participants in both sexes. Participants with diabetes reported a higher rate of OAB (43.1%) and increased bothersome symptoms associated with OAB than those without diabetes. Participants with diabetes (OR, 3.07 [2.39-3.96]], urgent incontinence (OR, 2.38 [1.86-3.03]), frequency (OR, 1.86 [1.45-2.38]), and nocturia (OR, 1.14 [1.05-1.24]) were associated with healthcare-seeking behavior.

CONCLUSION

The proportion of diabetic participants with OAB was 2.5-fold higher than those without diabetes. Diabetes, urinary frequency, nocturia, and urgent incontinence are predictors of medical treatment-seeking behavior, but the key symptom of OAB-urgency is not a predictor of treatment-seeking behavior. It is important for clinicians to recognize the interplay between diabetes and OAB and to early identify various bothersome urinary symptoms for better health outcomes in daily practice.

Advanced-stage presentation of cancer at the time of diagnosis and its associated factors among adult cancer patients at Northwest Amhara comprehensive specialized hospitals, Northwest Ethiopia 2022

INTRODUCTION

Screening of cancer is the maximum effort and critical element for providing health related care in order to decrease cancer related dealt because of the disease burden is in its advanced stages. Unfortunately, advanced-stage presentation and late diagnosis of cancers endure a problem in low-income countries including Ethiopia. However, there is scarcity of published articles about the problem in Ethiopia.

OBJECTIVE

This study aimed to assess the prevalence of advanced-stage -stage presentation of cancer at the time of diagnosis and associated factors among adult cancer patients at Northwest Amhara comprehensive Specialized Hospitals, oncology treatment units, Northwest Ethiopia, 2022.

METHODS

An institution based cross-sectional study was conducted in Northwest Amhara public referral hospitals on 422 study participants. A systematic random sampling technique was performed. The data were collected through face to face interview and document review via structured, pretested questionnaires. Epi. Data version 4.6 and Stata version 14.0 software's were used for data entry and analysis respectively. Logistic regression were carried out to recognize factors associated with advanced-stage -stage presentation of cancer at the time of diagnosis. Adjusted odds ratio with a 95% confidence interval were used to measure the strength of association. Variables having p-value less than 0.2 in bivariable analysis were entered in to multivariable analysis; variables with a p-value < 0.05 were declared significantly associated with advanced-stage -stage presentation of cancer at the time of diagnosis.

RESULTS

The overall prevalence of advanced-stage presentation of cancer at the time of diagnosis was found to be 67.57%. Age ≥ 60 years old patients (AOR = 6.10, 95%: (1.16-32.1)), patients had have a feeling of burden (AOR = 1.82, 95%, CI: (1.04-3.20)), and cancer patients with comorbidity illness (AOR = 2.40, 95%, CI: (1.40-4.12)) were significantly associated with advanced-stage presentation of cancer at the time of diagnosis.

CONCLUSION

The prevalence of advanced-stage presentation of cancer at the time of diagnosis was found to be high. Its better, health care providers in oncology treatment facilities need to give special attention to older patients, having feeling of burden and cancer patient with comorbidity to reduce the risk of developing late stage presentation of cancer.

[Sleep quality in patients with chronic kidney disease on hemodialysis]

Background

Chronic kidney disease (CKD) is a serious condition that impairs sleep quality, which compromises quality of life, cardiovascular function and increases the risk of mortality; however, limited information is available on sleep quality in hemodialysis (HD) patients.

Objective

To determine the sleep quality in patients with CKD on renal replacement therapy with HD.

Material and methods

Cross-sectional analytical study. The population included patients with CKD on HD, either sex, who answered the Pittsburgh questionnaire in a tertiary hospital. A 19-item self-administered survey was applied, assessing 7 components of sleep quality, where overall scores ≤ 5 and > 5 indicated respectively good and poor sleep quality. Socio-demographic, anthropometric, self-reported lifestyle and CKD history-related characteristics were assessed.

Results

A total of 83 patients were included with a mean age of 45.3 (15.9), 63% (52) were male and 37% (31) female; of these, 63% (52) had poor sleep quality and 37% (31) had good sleep quality.

Conclusion

Sleep quality is poor in patients with CKD on renal replacement therapy with HD. Variables influencing sleep quality are age, occupation, body mass index, sleep duration, and use of hypnotic medications. Therefore, HD patients should be evaluated to detect sleep problems in order to develop strategies to improve their sleep quality.

Efficacy of acupoint application in patients with overactive bladder: A randomized, placebo-controlled pilot trial

OBJECTIVE

Conventional treatments for alleviating the symptoms of Overactive bladder (OAB) have been reported to have limited efficacy and a high rate of side effects. Traditional Chinese medicine (TCM) has been used in Asia countries because of its low side effects and being easy to operate. To confirm the efficacy of acupoint application treatment for alleviating OAB symptoms, a randomized and placebo-controlled pilot trial was conducted in this study.

METHODS

All participants were randomly allocated into a treatment group or control group, receiving either a "Dinggui" acupoint application or placebo treatment for 4 weeks. The outcome measures were OAB symptom scores (OABSS), OAB questionnaire (OAB-q) scores, and TCM syndrome scores. Urine nerve growth factor (NGF) level, NGF normalized to urine creatinine (NGF/Cr), and maximum flow rate (Qmax) were also measured to evaluate the OAB symptoms.

RESULTS

In total, 69 participants were included with 34 in the treatment group and 35 in the placebo-treated group. Treatment with "Dinggui" acupoint application showed a statistically significant decrease in OABSS scores (8.10±1.54 to 3.67±1.77), OAB-q scores (61.43±13.93 to 38.13±15.42), and TCM syndrome scores (15.60±5.98 to 9.20±4.82). The NGF and NGF/Cr were also observed meaningful changes in a decrease from 379.68 to 136.17 pg/ml and from 0.30 to 0.16 pg/mg, respectively. The Qmax value showed a significant increase from 14.40 to 24.05 ml/s.

CONCLUSIONS

Treatment with "Dinggui" acupoint application could be considered an effective and alternative therapy for OAB management. Further studies with larger sample sizes and longer treatment periods are needed to investigate.

Cross-sectional study of depression tendency and sleep quality in 1352 people practicing Tai Chi

This cross-sectional study aimed to analyse the relationship between Tai Chi exercise habits and depression tendency and sleep quality in people practicing Tai Chi in Chengdu, China. A total of 1352 Tai Chi practitioners aged 50-79 years old were divided into six groups according to age and gender for Tai Chi exercise habits, depression tendency and sleep quality. The frequency of weekly Tai Chi practice and duration of single Tai Chi practice have a significant positive correlation with the exercise years. For female subjects who had long-term Tai Chi exercise, depression decreased with the duration and weekly frequency of a single exercise. Tai Chi exercise habits reduced sleep disturbance scores (in the male group aged 60-69 years old, exercise years, r = -0.242, p = 0.004) and sleep duration (in the male and female group aged 70-79 years old, duration of single Tai Chi practice, r = -0.334, p = 0.035; r = -0.235, p = 0.029), suggesting that long-term Tai Chi exercise may reduce the trend of poor sleep quality due to increased ageing.

Satisfaction of health informatics professionals with Ethiopian health system: the case of three zones in Ethiopia

BACKGROUND

The importance of the health information system faces multiple challenges such as supply, acceptance, and pressure from other professions in Ethiopia. Work-related challenges might cause low professional satisfaction and hinder service provision. There is a paucity of evidence for policy decisions to improve these challenges. Therefore, this study aims to assess Health Informatics professional satisfaction in the Ethiopian health system and associated factors to provide evidence for future improvements.

METHODS

We conducted an institutions-based cross-sectional study on health informatics professionals in three zones in Southern Ethiopia in 2020. We used a simple random sampling technique to select 215 participants. The local health officials were contacted regarding the research questions, and letters of permission were collected for data collection.

RESULTS

Out of 211(98%) Health Informatics professionals who accepted the interview, 50.8% (95%CI: 47.74%-53.86%) were satisfied. Age (AOR = 0.57; 95% CI: 0.53, 0.95), experience (AOR = 5; 95% CI: 1.50, 19.30), working time (AOR = 1.35; 95% CI: 1.10, 1.70), working as HMIS officers (AOR 2.30; 95% CI: 3.80, 13), single marital status (AOR = 9.60; 95% CI: 2.88, 32), and urban residence (AOR = 8.10; 95% CI: 2.95, 22) were some of the associated factors.

CONCLUSIONS

We found low satisfaction among health informatics professionals compared to other studies. It was suggested that the responsible bodies must keep experienced professionals and reduce pressure from other professions through panel discussions. Work departments and working hours need consideration, as they are the determinants of satisfaction. Improving educational opportunities and career structure is the potential implication area.

Cross-Cultural Adaptation and Measurement Properties of the Upper Limb Functional Index (ULFI) for Greek-Speaking Patients

INTRODUCTION

The upper limb functional index (ULFI) is a widely used outcome measure for patients with upper limb musculoskeletal disorders (ULMSDs) that is available in several languages. Our purpose was to develop the Greek version of the ULFI and test its test-retest reliability, validity, and responsiveness in a cohort of patients with ULMSD.

METHODS

We used a merged methodology of published guidelines and recommendations for the translation and cross-cultural adaptation process. One hundred patients with ULMSDs completed the ULFI-Gr on three occasions: baseline, 2-7 days later to evaluate repeatability, and 6 weeks later to assess responsiveness. Participants completed the quick disability of the arm, shoulder, and hand questionnaire (Quick-DASH) and a numerical pain rating scale (NPRS) to evaluate convergent validity. Also, a global rating of change (GROC) scale was used to evaluate responsiveness.

RESULTS

Minor wording adaptations were required during the translation and cross-cultural adaption of the questionnaire. Factor analysis resulted in two main factors explaining 40.2% of the total variance. The ULFI-Gr was found to be reliable (intraclass correlation coefficient: 0.97, 95% confidence interval: 0.95-0.99) with a small measurement error (standard error of measurement: 3.34%, minimal detectable change: 7.79%). The ULFI-Gr showed a strong negative correlation with the Quick-DASH (-0.75), a moderate to strong negative correlation with the NPRS (-0.56), and a good level of responsiveness (standardized response mean: 1.31, effect size: 1.19).

CONCLUSIONS

The ULFI-Gr can be used as a reliable, valid, and responsive patient-reported outcome measure to evaluate the functional status of patients with ULMSDs.

Cold stress-induced bladder overactivity in type 2 diabetic mellitus rats is mitigated by the combination of a M3 -muscarinic antagonist and a β3 -adrenergic agonist

OBJECTIVES

Goto-Kakizaki (GK) rats with type 2 diabetes mellitus respond to low temperature (LT) environments with bladder overactivity, including increased voiding frequency and decreased voiding interval and micturition volume. We determined if bladder overactivity could be inhibited by treatment with the combination of a M₃ -muscarinic receptor antagonist and a β₃ -adrenergic receptor agonist.

METHODS

Ten-week-old female GK rats were fed a high-fat diet for 4 weeks. Cystometric investigations were conducted at room temperature (RT, 27 ± 2°C). The rats were then intraperitoneally administered the vehicle, the M₃ -muscarinic receptor antagonist solifenacin, the β₃ -adrenergic agonist mirabegron, or a combination of solifenacin and mirabegron. Ten minutes after the administrations, the rats were transferred to the LT environment (4 ± 2°C), where the cystometric measurements were continued. The expressions of both M₃ -muscarinic and β₃ -adrenergic receptors were investigated.

RESULTS

After transfer from RT to LT, both voiding interval and bladder capacity of the vehicle-, solifenacin-, or mirabegron-treated rats were significantly decreased. However, the combination of solifenacin and mirabegron significantly mitigated the bladder overactivity. While both M₃ -muscarinic and β₃ -adrenergic receptors were detected, the expression of M₃ -muscarinic receptor mRNA was significantly higher than that of β₃ -adrenergic receptor mRNA.

CONCLUSIONS

The cold stress-induced bladder overactivity was not improved by either the M₃ -muscarinic receptor antagonist or the β₃ -adrenergic receptor agonist alone. However, the combined treatment mitigated the cold stress responses. Combined therapy with M₃ -muscarinic antagonists and β₃ -adrenergic agonists could reduce side effects and improve the quality of life for diabetic patients with bladder overactivity.

The performance of the EQ-5D-Y-5L compared to the EQ-5D-Y-3L in children and adolescents with cerebral palsy (CP)

Objectives

The aim of this study is to compare the performance and validity of the EQ-5D-Y-3L (Y-3L) and EQ-5D-Y-5L (Y-5L) in South African children and adolescents with cerebral palsy (CP).

Methods

Children/adolescents with CP and those from the general population completed the Y-5L, Y-3L, and PedsQL. Physiotherapists at the school classified participants' functional ability on the Gross Motor Functioning Classification System (GMFCS).

Results

Fifty-one children/adolescents completed the measures. The ceiling effect had a 44% relative reduction for Mobility and floor effects decreased across all dimensions except for Looking After Myself when moving from the Y-3L to Y-5L. Informativity of dimensions improved on average by 0.27 on the Y-5L with similar evenness. There was a range of 6-16% inconsistent responses when moving from the Y-3L to the Y-5L. Convergent validity was strong on paired Y-3L and Y-5L dimensions: Kendall's Tau B (range 0.53 - 0.85) and Gamma (range 0.79 - 0.99). There was significant moderate association between Y-3L and Y-5L with similar items on the PedsQL. The physical dimensions of Mobility, Looking After Myself and Usual Activities were significantly associated with GMFCS with those having less independent mobility reporting more severe problems on dimension scores.

Conclusion

The Y-5L showed a notable reduction in ceiling and floor effects, improved discriminatory power, higher criterion validity with the GMFCS and similar concurrent validity with the PedsQL as the Y-3L. It is recommended that the Y-5L is further tested for reliability and responsiveness in this population group so that its utility for detecting change in clinical trials or as a routine outcome measure can be determined.

Depression and its associated factors among primary caregivers of adult cancer patients at Northwest Amhara Regional States Referrals Hospitals oncology treatment units, Northwest Ethiopia, 2021

INTRODUCTION

Cancer is a primary and challenging health problem, has a significant impact on caregivers, and is a leading cause of emotional responses like depression. Depression is the most common and serious psychiatric disorder that has a considerable effect on the daily life of primary caregivers. Different articles reported that the magnitude of depression was prevalent among primary caregivers of patients with cancer. There is scarcity of published articles about the problem in Ethiopia. This study aimed to assess the prevalence of depression and associated factors among primary caregivers of adult cancer patients at Northwest Amhara Regional States Referrals Hospitals, oncology treatment units, Northwest Ethiopia, 2021.

METHODS

An institutional-based cross-sectional study was conducted in Northwest Amhara Regional States Referrals Hospitals. A systematic random sampling technique was used to select 421 participants. The data were collected using interviewer-administered and chart review through structured, pretested Patient Health Questionarie-9 questionnaires. The data were entered into Epi. Data version 4.6 and analyzed using Stata version 14.0. Bivariable and multivariable logistic regression were carried out to identify factors associated with depression. Adjusted odds ratio with a 95% confidence interval and variables with a p-value < 0.05 were considered significantly associated with depression.

RESULTS

The prevalence of depression was 45.15%. Being female (AOR = 2.01, 95%, CI: 1.27-3.19), having an average monthly income of < 1000 Ethiopian birr (AOR = 3.54, 95% CI: 1.54-8.13), and primary caregivers of a cancer patient with mixed therapy (AOR = 4.54, 95%, CI: (1.5-13.48) were significantly associated with depression.

CONCLUSION

The prevalence of depression among primary caregivers of adult patients with cancer was significant. It's better, health care providers in oncology treatment facilities need to recognize and screen and give special attention to female primary caregivers, having an average monthly income of < 1000 Ethiopian birr, and primary caregivers of a cancer patient with mixed therapy to reduce the risk of developing depression.

Learning and quality of life in undergraduate nursing students: An exploratory study in Chile during the COVID-19 pandemic

BACKGROUND

Coronavirus disease 2019 (COVID-19) is a global pandemic that has modified all social and, especially, learning instances. The purpose of this study was to determine the perception of final-year nursing students at a university in southern Chile regarding the impact of the pandemic on their learning, and consequently on their quality of life, in the context of the COVID-19 pandemic.

MATERIALS AND METHODS

This is a qualitative study. The research was conducted on 14 nursing students who were selected from a university located in the province of Talca, Maule Region, Chile. Data collection was done through semi-structured interviews conducted during July and September 2021. The data were analyzed using the inductive logic of theoretical categorization; this process was assisted by the Nvivo 10 program.

RESULTS

Two mega categories were generated that accounted for the nursing students' experience during the COVID-19 pandemic: objective factors category and subjective factors category. Six subcategories were derived from these two categories: free time, social relationships, learning from practice, physical exercise, eating habits, and emotional state.

CONCLUSION

The research findings indicate that the students, in addition to feeling upset about not being able to do the internship, also feel that they have not been able to acquire all the knowledge necessary for their training and professional development, since the virtual classes fail to deliver adequate learning as they lack the practical component that is so important in their careers. This has repercussions in the physical, social, and psychological areas, affecting their quality of life.

Multimorbidity patterns and hospitalisation occurrence in adults and older adults aged 50 years or over

Multimorbidity is highly prevalent in older adults and can lead to hospitalisation. We investigate the prevalence, associated factors, and multimorbidity pattern associated to hospitalisation, readmission, and length of stay in the population aged 50 years and older. We analysed baseline data (2015–2016) from the ELSI-Brazil cohort, a representative sample of non-institutionalised Brazilians aged ≥ 50 years. In total, 8807 individuals aged ≥ 50 years were included. Poisson regression with robust variance adjusted for confounders was used to verify the associations with hospitalisation. Multiple linear regression was used to analyse the associations with readmission and length of stay. Network analysis was conducted using 19 morbidities and the outcome variables. In 8807 participants, the prevalence of hospitalisation was 10.0% (95% CI 9.1, 11), mean readmissions was 1.55 ± 1.191, and mean length of stay was 6.43 ± 10.46 days. Hospitalisation was positively associated with male gender, not living with a partner, not having ingested alcoholic beverages in the last month, and multimorbidity. For hospital readmission, only multimorbidity ≥ 3 chronic conditions showed a statistically significant association. Regarding the length of stay, the risk was positive for males and negative for living in rural areas. Five disease groups connected to hospitalisation, readmission and length of stay were identified. To conclude, sociodemographic variables, such as gender, age group, and living in urban areas, and multimorbidity increased the risk of hospitalisation, mean number of readmissions, and mean length of stay. Through network analysis, we identified the groups of diseases that increased the risk of hospitalisation, readmissions, and length of stay.

Determinants of oral-health-related quality of life among adult people in Iran

BACKGROUND

Oral health-related quality of life (OHRQoL) assesses the subjective perception of oral health and its impact on the quality of life. The aim of this study is to measure the OHRQoL and its determinants among adult people living in Kerman, Iran.

MATERIALS AND METHODS

In this cross-sectional study, a total of 5657 adult people (18-64 years) residing in the Kerman district, both in the rural and urban areas, were enrolled in the study between September 2014 and April 2018. The Oral Health Impact Profile (OHIP-14) and the oral health indices, such as the total decayed, missing, filled teeth (DMFT), community periodontal index (CPI), gingival index (GI), and xerostomia, were measured by an experienced dentist. The demographic variables of gender, age, educational status, and marital status were also recorded. The impact of the studied variables on OHRQoL was evaluated with multiple logistic regression.

RESULTS

Participants were 2239 (39.58%) men, and average age was 45.39. The mean scores for OHRQoL, DMFT, CPI and GI were respectively: 24.07 (7.76), 10.7 (6.86), 0.76 (0.96), 0.63 (0.8). The frequency of people with xerostomia was 37.4. 301 (53.3%) of people had poor quality of life related to oral health. In multivariable analysis, there was a statistically significant increase in OHRQoL with an increase in the DMFT (P < 0.001), xerostomia (P < 0.001), CPI, (P < 0.001). Men had a significantly higher OHIP score than women (P < 0.001).

CONCLUSION

According to the results of this study, DMFT, xerostomia, and CPI scores are strongly related to OHIP scores. In addition, between CPI and GI scores, the CPI score is the better predictor.

Quantifying Societal Burden of Radiation-Induced Cardiovascular Events in Breast Cancer Survivors

Background and Purpose

Radiation-induced cardiotoxicity is an important health concern for clinicians during treatment of breast cancer (BC) patients. Underlying mechanisms are well-documented, whereas little is known about the societal impact of this long-term effect. This study aimed to quantify the additional burden of radiation-induced cardiovascular (CV) diseases in BC survivors.

Materials and Methods

Conventional health economic modelling techniques were applied to estimate attributed CV-related costs and disutility in a hypothetical cohort of BC survivors. A situation in which radiotherapy caused an additional CV risk was compared with a situation in which this risk was not taken into account. Uncertainty was assessed via deterministic and probabilistic sensitivity analyses. Analyses were performed from a broad societal perspective up until 20 years after BC treatment.

Results

Radiation-induced cardiotoxicity evokes a mean incremental cost of €275.10 per woman over a time horizon of 20 years after BC treatment. An additional decrement of 0.017 QALYs (per woman) might be expected when taking the radiation-induced cardiotoxic risk into account in BC survivors. Incremental costs and disutility increased with age. A scenario analysis showed that these results were more profound in women with more advanced staging.

Conclusion

Our analyses suggest that with current radiation techniques, rather minor costs and disutility are to be expected from radiation-induced cardiotoxicity in BC survivors. The cost of past investments in order to achieve current mean heart dose (MHD) seems justified when considering the gains from cost and disutility reduction resulting from radiation-induced cardiovascular events. The question we might consider is whether future opportunity costs associated with investments on further technological advancements offset the expected marginal benefit from further reducing the MHD.

Measurement properties of the EQ-5D-Y administered through a smartphone app in children with asthma: a longitudinal questionnaire study

BACKGROUND

Asthma impacts children's physical, emotional, and psychosocial Health-Related Quality of Life (HRQL). The EQ-5D-Y is a generic econometric instrument developed to measure HRQL in children.

OBJECTIVE

Evaluation of feasibility, validity, reliability, and responsiveness of EQ-5D-Y descriptive system and utility index to allow the assessment of HRQL in children with asthma, aged 8-11 years (self-response version) or under 8 years old (proxy-response version).

METHODS

We used data from baseline to 10 months of follow-up of an observational, prospective study of children with persistent asthma recruited by pediatricians in Spain (2018-2020). HRQL instruments were administered through a smartphone application: ARCA app. The EQ-5D-Y is composed of a 5-dimension descriptive system, a utility index ranging from 1 to - 0.5392, and a general health visual analogue scale (EQ-VAS). The Pediatric Asthma Impact Scale (PROMIS-PAIS) includes 8 items, providing a raw score. Construct validity hypotheses were stated a priori, and evaluated following two approaches, multitrait-multimethod matrix and known groups' comparisons. Reliability and responsiveness subsamples were defined by stability or change in EQ-VAS and the Asthma Control Questionnaire (ACQ), to estimate the intraclass correlation coefficient (ICC) and the magnitude of change over time.

RESULTS

The EQ-5D-Y was completed at baseline for 119 children (81 self-responded and 38 through proxy response), with a mean age of 9.1 (1.7) years. Mean (SD) of the EQ-5D-Y utility index was 0.93 (0.11), with ceiling and floor effects of 60.3% and 0%, respectively. Multitrait-multimethod matrix confirmed the associations previously hypothesized for the EQ-5D-Y utility index [moderate with PROMIS-PAIS (0.38) and weak with ACQ (0.28)], and for the EQ-5D-Y dimension "problems doing usual activities" [moderate with the ACQ item (0.35) and weak with the PROMIS-PAIS item (0.17)]. Statistically significant differences were found in the EQ-5D-Y between groups defined by asthma control, reliever inhalers use, and second-hand smoke exposure, with mostly moderate effect sizes (0.45-0.75). The ICC of the EQ-5D-Y utility index in the stable subsamples was high (0.81 and 0.79); and responsiveness subsamples presented a moderate to large magnitude of change (0.68 and 0.78), though without statistical significance.

CONCLUSIONS

These results support the use of the EQ-5D-Y as a feasible, valid, and reliable instrument for evaluating HRQL in children with persistent asthma. Further studies are needed on the responsiveness of the EQ-5D-Y in this population.

A Community-Based Education Program for Overactive Bladder in a Predominantly Minority Older Female Population: A Pilot Study

Introduction

Knowledge gaps regarding available treatment and social stigmatization are barriers to care in patients with overactive bladder (OAB). We assessed the feasibility of an OAB education program targeting older community-dwelling females.

Methods

Community-dwelling women over 55 years old were recruited. Eligible participants underwent an education program covering continence-promotion strategies. The Overactive Bladder Questionnaire-Short Form and Short Form-12 were completed at baseline, 1 week, 3 months, and 6 months post-intervention to measure symptom bother and condition-specific and general quality of life (QoL). Data were analyzed using a linear mixed-effects model for repeated measures.

Results

Thirty-seven female patients with OAB symptoms at baseline were assessed with the majority from Latino/Hispanic or Black/African American ethnic/racial backgrounds. For our youngest subgroup (≤68 years old), significant improvements were observed at 3 and 6 months compared to 1 week post-intervention for symptom bother (3 months, −22.75, p = 0.006; 6 months, −25.76; p = 0.001) and condition-specific and health-related QoL subscale scores for concern (3 months, +23.76, p = 0.006; 6 months, +22.15, p = 0.011) and social interaction (3 months, +21.11, p = 0.017; 6 months, +20.51; p = 0.021). For all age subgroups, improvements in general QoL measures for mental health were seen at 3 and 6 months compared to baseline (3 months, +7.57, p = 0.02; 6 months, +6.70; p = 0.048).

Conclusions

Statistically significant improvements in symptom bother, condition-specific, and general QoL measures were observed following an OAB education program pilot study in a predominantly minority female population. Further studies are needed to support efficacy and optimize program design.

The significance of sleep quality in euthymic bipolar patients from Nigeria

Background

Bipolar disorder is highly under-researched in Africa. Existing studies show that racial/ethnic disparities exist for sleep quality. Poor sleep quality in bipolar disorder causes significant morbidity and mortality even during periods of euthymia.

Aim

This study aimed to assess sleep quality and its correlates amongst euthymic patients with bipolar I disorder from Nigeria.

Setting

The study was carried out in a teaching hospital, and state hospital, in Ibadan, Nigeria.

Method

This cross-sectional study was conducted amongst 76 euthymic bipolar patients aged between 18 and 60 years, meeting the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnostic criteria for bipolar disorder. Euthymia was defined as having a score of ≤ 5 on the Young Mania Rating Scale and < 8 on the Hamilton Depression Rating Scale. Sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI).

Results

A total of 37 (48.7%) participants had poor quality sleep. Sleep quality was associated with marital status (p = 0.013) and suicide plan (p = 0.047). Participants with good sleep quality had higher total sleep duration, lower time to fall asleep (sleep latency), better subjective quality of sleep, were less likely to use sleep medications and had less daytime dysfunction than participants with poor sleep quality. All p-values were < 0.05. Subjective quality of sleep, ongoing use of sleep medication, daytime dysfunction were independently associated with poor sleep quality.

Conclusion

Poor sleep quality frequently persists during euthymic periods in patients with bipolar disorder. The correlates identified can be targeted for intervention during treatment.

Validation of the Modified Schein Dry Eye Symptom Questionnaire and Comparison With the Ocular Surface Disease Index

Purpose

This study evaluated the validity and diagnostic efficacy of a modified Schein dry eye questionnaire and compared it to the Ocular Surface Disease Index (OSDI).

Methods

The original Schein survey was modified to allow numerical scoring on a 0 to 24 scale and evaluated in prospective studies in normal and dry eye subjects. Receiver operating characteristic (ROC) analysis for test efficacy in aqueous deficient dry eye (ADDE) and evaporative dry eye (EDE) related to meibomian gland dysfunction was determined.

Results

Dry eye subtype, age and gender were statistically significant in explaining variation in modified Schein scores (n = 377; general linear model; all P values < 0.006) whereas for Ocular Surface Disease Index (OSDI) only age and gender were significant, but not dry eye subtype. The modified Schein ROC curve had an area under the curve (AUC) of 0.693 (95% confidence interval [CI], 0.635–0.753), with cutpoint of 7.5 (sensitivity of 0.75, specificity of 0.55). Similarly, the OSDI had an AUC of 0.685 (95% CI, 0.610–0.760), at a cutpoint of 10.4 (sensitivity of 0.75, specificity of 0.55). Modified Schein and OSDI correlated well (Pearson r = 0.81; P < 0.001). Symptom change for the modified Schein with artificial tear treatment was significant in EDE subjects (Dunnet's tests, P value < 0.001).

Conclusions

The modified Schein questionnaire is rapid to administer and score and compares well with the OSDI for test efficacy. Moreover, it differentiates normals from ADDE and EDE subtypes and is responsive to dry eye treatment. These attributes make the modified Schein survey an attractive dry eye symptom characterization instrument.

Translational Relevance

The modified Schein symptom survey, validated against clinical diagnosis and an existing survey, provides a new, efficacious diagnostic and treatment monitoring instrument in dry eye disease.

Is Vitamin D Important in Anxiety or Depression? What Is the Truth?

PURPOSE OF REVIEW

Depression and anxiety are mood disorders that affect health and therefore quality of life and increase the global burden of disease. One of the possible mechanisms in the pathophysiology of these mood disorders has been reported as oxidative stress and inflammation. In the light of this information, it is important to determine the relationship between antioxidant nutrients (such as vitamin D) and these diseases. There are points where the brain regions involved in the pathophysiology of depression and anxiety and vitamin D metabolism intersect.

RECENT FINDINGS

Low vitamin D levels are associated with increased symptoms of depression and anxiety. For this reason, vitamin D screening should be performed in the prevention and treatment planning of these mood disorders. Vitamin D, which has antioxidant properties and activity in brain tissue, is important for mood disorders preventions or treatments but serum levels must be followed.

Global Systematic Review of Common Mental Health Disorders in Adults Living with HIV

PURPOSE OF THE REVIEW

By reviewing the most recent common mental health disorders (CMHD) studies in people living with HIV (PLWH) (2018-2020), this review discusses the prevalence of CMHD, factors associated with CMHD in PLWH, mental health in PLWH from vulnerable groups, the impact of CMHD on HIV disease progression and adherence to antiretroviral therapy and the efficacy of different treatment approaches.

RECENT FINDINGS

After screening for eligibility 142 studies were included in the final systematic review. Only 27% of studies were conducted in Sub-Saharan Africa, which carries the highest burn of HIV disease globally. Despite the well-established increased risk of CMHD in PLWH, the current prevalence remains high, with studies reporting 28%-62% of PLWH having mental health symptoms.

CONCLUSION

Despite the significant challenges that CMHDs present to successful HIV treatment, there are many mental health treatments and interventions which can improve outcomes in PLWH and opportunities to task-shift and integrate mental health care with HIV care.

Randomized Controlled Trial Study of the Impact of a Spiritual Intervention on Hope and Spiritual Well-Being of Persons with Cancer

OBJECTIVES

To determine the impact of spiritual intervention on hope and spiritual well-being of persons with cancer.

METHODS

Randomized controlled trial in which 74 patients with cancer referring to a chemotherapy ward of Shahid Rajaie Hospital in Yasuj city, Iran, were participated. The eligible patients were randomly assigned to either intervention or control group. Spiritual-based intervention was performed based on the protocol in four main fields namely; religious, existence, emotional and social over 5 sessions before chemotherapy. The participants in the control group had received usual cares. Data were collected using Snyder's Hope Scale and Ellison's Scale Spiritual Well-Being Scale on a week before and after intervention.

RESULTS

The total mean scores of the scales of hope and spiritual well-being in both groups did not present statistical differences in the pre-intervention assessment. In contrast, at the post assessment, significant differences (p<0.001) were found in the mean scores between the intervention and control groups on the hope scale (60.9 versus 39.8) and on the spiritual well-being scale (94.3 versus 71.6).

CONCLUSIONS

Spiritual intervention could promote hope and spiritual well-being of persons with cancer.

Association of decreased grip strength with lower urinary tract symptoms in women: a cross-sectional study from Korea

BACKGROUND

Lower urinary tract symptoms (LUTS) including frequency, nocturia, urgency, and incontinence, are common in women and cause significant discomfort in daily life. However, diagnosis and treatment of LUTS are often delayed because many patients with such symptoms do not complain to the physician of discomfort and do not seek medical attention. LUTS are known to be associated with muscle weakness. We investigated the association between grip strength and LUTS in women of different ages.

METHODS

This study included 4225 women (mean age 48.6 years) who underwent self-referred health screening between April 2015 and December 2019. LUTS were evaluated using a self-reported questionnaire, and the overactive bladder symptom score was used to screen for an overactive bladder. Low muscle strength was defined as a hand grip strength of < 18 kg (decreased grip strength).

RESULTS

We observed decreased grip strength in 13.7% (n = 580) of the participants. Nocturia, urgency, incontinence, and overactive bladder were more common in women with decreased grip strength than in women with normal grip strength. After adjusting for age, comorbidities (hypertension, diabetes, hyperlipidemia), smoking status, alcohol consumption, regular exercise, and stress, nocturia (odds ratio [OR] 1.19, 95% confidence interval [CI] 1.01-1.52), urinary incontinence (OR 1.32, 95% CI 1.01-1.72), and an overactive bladder (OR 1.75, 95% CI 1.35-2.27) were significantly associated with decreased grip strength.

CONCLUSIONS

The findings suggest that LUTS, especially nocturia, incontinence, and an overactive bladder are associated with decreased grip strength in women. Therefore, physicians should be aware that patients may not seek help, even if they are uncomfortable, and it is important to obtain a detailed medical history and perform additional tests, even in the absence of complaints, in patients with low grip strength, who are at high risk of LUTS.

Factor structure and psychometric properties of a Polish adaptation of the Warwick-Edinburgh Mental Wellbeing Scale

Background

The study of mental wellbeing requires reliable, valid, and practical measurement tools. One of the most widely used measures of mental wellbeing is the Warwick–Edinburgh Mental Wellbeing Scale (WEMWBS). We conducted four studies to validate the Polish version of the WEMWBS. Their objectives are the following: (1) to present the psychometric properties of the Polish version of the WEMWBS (study 1: n = 1197); (2) to evaluate the test–retest reliability of the Polish version of the WEMWBS (study 2: n = 24); (3) to determine the validity of the WEMWBS (study 3: n = 610); (4) to examine sensitivity of the WEMWBS scale to detect population with different levels of pro-health behaviours (study 4: n = 430).

Methods

To explore the dimensional structure of the scale we tested a one-factor model. The evaluation employed explanatory and confirmatory factor analyses and tested reliability and stability. To determine the convergent validity of the WEMWBS we analysed correlations among wellbeing and life satisfaction and risk depression. To examine sensitivity of the WEMWBS scale to detect a population with different levels of health-related behaviours we used Student’s t test.

Results

The results presented confirm that the psychometric properties of the Polish adaptation of WEMWBS are very good. Using EFA and CFA it was shown that a one-factor solution is optimal. Reliability, measured using the Cronbach’s alpha coefficient and McDonald's omega proved to be very high. The estimation of the stability of the Polish version of the WEMWBS proved to be high. Our validation studies also provided data demonstrating sensitivity of the WEMWBS to detect a population with different levels of health-related behaviours, indicating that group with high level of pro-health behaviours achieved higher WEMWBS wellbeing results than group with low level of pro-health behaviours.

Conclusions

WEMWBS was confirmed as a short, reliable and valid measure with good psychometric properties. Due to the high indicators for its psychometric properties, the scale may therefore prove to be a particularly useful tool not only in empirical research, but also in mental wellbeing monitoring, and could serve as support in educational and preventive.

Validating 7-items Overactive Bladder Symptom Score (OABSS) through Arabic linguistic version

The scoring of the 7-item Overactive Bladder Symptom Score (OABSS) questionnaire is unusual because its scale varies with the same maximum and minimum scoring values and quantifies all aspects of OAB. The questionnaire also contains a graded response for urgency. The current study is mainly concerned with the development and validation of the OABSS questionnaire for Jordanian patients. The process of translating the English OABSS questionnaire into the Arabic language involved forward and backward translations. Afterward, a prospective study was conducted to validate the Arabic version of the OABSS questionnaire by examining 235 patients from the outpatient clinics of Karak Governorate Teaching Hospital. The Arabic OABSS questionnaire was completed by all the enrolled patients before and after three months of treatment with solifenacin 5 mg taken once daily. The study included 235 regular patients (152 females and 83 males) diagnosed with OAB in accordance with the definition of the International Continence Society (ICS). The results showed major and significant differences on all seven domains of the questions on the OABSS questionnaire before and after receiving treatment (p < 0.05). Confirmatory Factor Analysis was used to measure the reliability and the questionnaire was found to be highly reliable for the construct variables. The findings derived from the current study would be beneficial for local urologists and researchers, as the Arabic version of the OABSS questionnaire was proven to be a reliable instrument for use in the assessment of OAB. Future studies are needed to compare different translated questionnaires relating to OAB.Trial registration number: NCT04309890.

The Pharmacological Mechanism of Diabetes Mellitus-Associated Overactive Bladder and Its Treatment with Botulinum Toxin A

Diabetes mellitus (DM) is an independent risk factor for overactive bladder (OAB). The pathophysiology of DM-associated OAB is multifactorial and time-dependent. Diabetic bladder dysfunction is highly associated with diabetic complications, mainly including diabetic neuropathy and atherosclerosis. Chronic systemic inflammation and bladder urothelial inflammation may contribute to the onset of OAB. Intravesical botulinum toxin A (BoNT-A) injection has proved to be a successful treatment for idiopathic and neurogenic OAB. BoNT-A can inhibit the efferent pathways of the bladder as well as the chronic inflammation and hypersensitivity via the afferent pathways. We conducted a review of the published literature in Pubmed using a combination of two keywords, namely “botulinum toxin A” (BoNT-A) and “overactive bladder”, with or without the additional keywords “detrusor overactivity”, “diabetes mellitus”, “inflammation”, and “urodynamic study”. We also reviewed the experience of our research teams, who have published several studies of the association between DM and OAB. Since limited data support the effectiveness and safety of BoNT-A for treating patients with DM-associated OAB, a comprehensive evaluation of diabetic complications and urodynamic study is needed before treatment. In the future, it is imperative to explore the clinical characteristics and inflammatory biomarkers of diabetes as determining predictors of the treatment efficacy.

Effectiveness of eHealth cardiac rehabilitation on health outcomes of coronary heart disease patients: a randomized controlled trial protocol

BACKGROUND

Cardiac rehabilitation (CR) uptake and adherence remain sub-optimal despite the apparent health benefits of modifying healthy behavior and slowing disease progression. eHealth is the use of information and communication technology (ICT) for health. eHealth lifestyle interventions and disease management have emerged as modalities to enhance CR accessibility, enable an individualized progress page, and enrich real-time contact, video-based information, and technology monitored functionality. This study aims to develop a nurse-led eHealth cardiac rehabilitation (NeCR) intervention and investigate its effectiveness on coronary heart disease (CHD) patients' health outcomes.

METHODS

This single-blinded two-arm parallel randomized controlled trial will randomize 146 patients from the inpatient cardiovascular units of a hospital in Wuhan, China to receive either the NeCR or the usual care. The NeCR intervention uses a hybrid approach consisting of a brief face-to-face preparatory phase and an empowerment phase delivered by health technology. The preparatory phase aims at identifying self-care needs, developing a goal-oriented patient centered action plan, incorporating a peer support network and orientation to the use of the e-platform. The empowerment phase includes use of the multi-media interactive NeCR for promoting symptom management, monitoring lifestyle changes and offering psychological support. A tele-care platform is also integrated to enhance health care dialogue with health professionals and peer groups. The control group will receive the usual care. An evaluation of lifestyle behavioral changes, self-efficacy, health-related quality of life, anxiety and depression, cardiovascular risk parameters, and unplanned health services use will be conducted at baseline, 6 weeks and 12 weeks post-intervention.

DISCUSSION

This protocol proposes an individualized, comprehensive, and interactive NeCR delivered using a hybrid approach and guided by an empowerment model to optimize health outcomes of CHD patients. The intervention content and web-design is based on international health guidelines to improve credibility, comprehensibility and implementation. This study also proposes a new method of peer support in which the researcher shares participants' progress toward goal attainment with the peer group. Results of this research have the potential to increase accessibility and availability of CR, improve cardiac rehabilitation service development in China, and inform eHealth lifestyle interventions.

Age-specific health-related quality of life in disease-free long-term prostate cancer survivors versus male population controls-results from a population-based study

BACKGROUND

Prostate cancer (PC) and its treatment may affect PC survivors differently with respect to age. However, little is known regarding age-specific health-related quality of life (HRQoL) in PC survivors 5 years or even ≥ 10 years post-diagnosis.

METHODS

The sample included 1975 disease-free PC survivors (5-16 years post-diagnosis) and 661 cancer-free population controls, recruited from two German population-based studies (CAESAR+, LinDe). HRQoL in both populations was assessed using the EORTC QLQ-C30 questionnaire. Additionally, PC survivors completed the PC-specific EORTC QLQ-PR25 questionnaire. Differences in HRQoL between survivors and controls, as well as differences according to age and time since diagnosis were analyzed with multiple regression after adjustment for age, education, stage, and time since diagnosis, where appropriate.

RESULTS

In general, PC survivors reported HRQoL and symptom-burden levels comparable to the general population, except for significantly poorer social functioning and higher burden for diarrhea and constipation. In age-specific analyses, PC survivors up to 69 years indicated poorer global health and social functioning than population controls. Stratification by time since diagnosis revealed little difference between the subgroups. On PC-specific symptoms, burden was highest for urinary bother and symptoms, and lowest for bowel symptoms. Younger age was associated with less urinary symptoms but higher urinary bother.

CONCLUSION

Long-term disease-free PC survivors reported overall good HRQoL, but experienced persistent specific detriments. Our data suggest that these detriments do not improve substantially with increasing time since diagnosis. Targeted interventions are recommended to prevent PC-related and treatment-related symptoms becoming chronic and to enhance social functioning.

Gender differences in the association between body mass index and health-related quality of life among adults:a cross-sectional study in Shandong, China

BACKGROUND

This study aims to assess the association between body mass index (BMI) and health-related quality of life (HRQOL), and to further explore gender differences in BMI-HRQOL association among adults.

METHODS

We used data from the fifth Health Service Survey of Shandong Province, which was part of China's National Health Service Survey (NHSS), a total of 27,257 adults aged 18 and over were interviewed. The HRQOL was measured using the EuroQOL-5 Dimensions (EQ-5D) instrument. One-way ANOVA and Post hoc tests were used to compare EQ-5D utility values and visual analogue scale (VAS) scores between BMI categories. Tobit regression models were used to identify the association between BMI and HRQOL for male and female separately after controlling for influential confounders, and to assess gender differences on the relationship between BMI and HRQOL.

RESULTS

The prevalence of underweight in men and women were 3.2 and 5.3%, respectively, while the prevalence of overweight/obesity in men and women were 35.7 and 34.6%, respectively. Men had higher EQ-5D utility values and VAS scores than women. The mean EQ-5D utility value and VAS score was highest in obese men and normal-weight women, respectively. After controlling potential confounders, being underweight was significantly and negatively associated with lower HRQOL among adults. The relationship between obesity and gender was that in women obesity was negatively and significantly associated with HRQOL, whereas in men this association was positive but not statistically significant. Results of gender by BMI interaction in regression model showed that this difference between men and women in this respect was significant.

CONCLUSIONS

The association between BMI and HRQOL differed by gender and the so-called "obesity-HRQOL paradox" phenomenon was verified in male adults. Gender difference should be considered when implementing targeted weight control programs and appropriate interventions to improve HRQOL.

Insomnia severity index: a psychometric investigation among Saudi nurses

BACKGROUND

Insomnia is the most prevalent sleep disorder, but it is widely untreated and under-diagnosed in Saudi Arabia. Moreover, no tool to screen insomnia has been validated in the Saudi population in general or nurses in particular. This study, therefore, assessed the psychometric validity of the Insomnia Severity Index (ISI) in Saudi nurses.

METHODS

A cross-sectional study with purposive sampling was performed with nurses (n = 134, age = 21-48 years) from Al Majmaah, Saudi Arabia. Both conventional and online survey methods using the ISI, a brief measure of metacognition, and a socio-demographics questionnaire were employed.

RESULTS

No ceiling or floor effects were found in the ISI total score (8.84 ± 5.07) or the factor scores, but the floor effect was found in the item scores. A two-factor model showed the best fit (Pclose .97, comparative fit index [CFI] 1.00, root mean square error of approximation [RMSEA] 0.00, non-significant χ²test, χ²/df 0.904). This model showed favorable configural, metric, scalar, and partial strict invariance across gender groups (CFI > .95, RMSEA < .05, χ²/df < 3, non-significant Δχ², ΔCFI ≤ .01). The internal consistency was adequate (Cronbach's alpha = 0.75, 0.78 for the two factors of the ISI). The lack of correlations between the ISI scores and the scores of the brief measure of the metacognition favored its divergent validity.

CONCLUSION

The ISI showed adequate psychometric validity for screening insomnia among Saudi nurses.

Mapping the FACT-B Instrument to EQ-5D-3L in Patients with Breast Cancer Using Adjusted Limited Dependent Variable Mixture Models versus Response Mapping

BACKGROUND

Preference-based measures of health, such as the three-level EuroQol five-dimensional questionnaire (EQ-5D-3L), are required to calculate quality-adjusted life-years for use in cost-effectiveness analysis, but are often not recorded in clinical studies. In these cases, mapping can be used to estimate preference-based measures.

OBJECTIVES

To model the relationship between the EQ-5D-3L and the Functional Assessment of Cancer Therapy-Breast Cancer (FACT-B) instrument, comparing indirect and direct mapping methods, and the use of FACT-B summary score versus FACT-B subscale scores.

METHODS

We used data from three clinical studies for advanced breast cancer providing 11,958 observations with full information on FACT-B and the EQ-5D-3L. We compared direct mapping using adjusted limited dependent variable mixture models (ALDVMMs) with indirect mapping using seemingly unrelated ordered probit models. The EQ-5D-3L was estimated as a function of FACT-B and other patient-related covariates.

RESULTS

The use of FACT-B subscale scores was better than using the total FACT-B score. A good fit to the observed data was observed across the entire range of disease severity in all models. ALDVMMs outperformed the indirect mapping. The breast cancer-specific scale had a strong influence in predicting the pain/discomfort and self-care dimensions of the EQ-5D-3L.

CONCLUSIONS

This article adds to the growing literature that demonstrates the performance of the ALDVMM method for mapping. Regardless of which model is used, the subscales of FACT-B should be included as independent variables wherever possible. The breast cancer-specific subscale of FACT-B is important in predicting the EQ-5D-3L. This suggests that generic cancer measures should not be used for utility mapping in patients with breast cancer.

The prevalence of lower urinary tract symptoms in population aged 40 years or over, in South Korea

Purpose

Lower urinary tract symptoms (LUTS) can be distressing and socially isolating, and the economic impact can be substantial. Further data to characterize the epidemiology and effects of LUTS in South Korea would be beneficial.

Materials and Methods

In an international, internet-based survey, the prevalence and impact of LUTS was evaluated in adults aged ≥40 years. Questions related to International Continence Society (ICS) symptom definitions and the bother associated with each symptom. The international prostate symptom score (IPSS) and the overactive bladder symptom score (OABSS) were assessed.

Results

Of the 2,080 participants from South Korea, 1,090 (52.4%) were women and 740 (35.6%) were aged ≥60 years. The prevalence of LUTS according to ICS criteria was 68.2% (men, 70.6%; women, 66.0%). LUTS prevalence increased significantly with age (p=0.01 in men and women). Storage symptoms only were reported in 16.2% of men and 30.5% of women, making this the most common ICS symptom group overall. Individual symptoms with the highest prevalence in the overall population were nocturia, frequency, and weak stream (36%, 30%, and 29%, respectively). IPSS results showed that 40.1% of participants had at least moderate symptoms. The prevalence of OABSS-defined overactive bladder was 19.7% (men, 19.5%; women, 19.9%). Fourteen percent of individuals with any LUTS visited healthcare professionals regarding urinary symptoms.

Conclusions

LUTS affect the majority of adults aged ≥40 years in South Korea. The low percentage of individuals with LUTS consulting healthcare professionals regarding urinary symptoms indicates a need to improve rates of diagnosis and treatment.
