Cultural issues in using the SF-36 Health Survey in Asia: results from Taiwan

Assessing the Clinical Effectiveness of an Exergame-Based Exercise Training Program Using Ring Fit Adventure to Prevent and Postpone Frailty and Sarcopenia Among Older Adults in Rural Long-Term Care Facilities: Randomized Controlled Trial

BACKGROUND

Frailty and sarcopenia are geriatric syndromes of increasing concern and are associated with adverse health outcomes. They are more prevalent among long-term care facility (LTCF) users than among community dwellers. Exercise, especially multicomponent and progressive resistance training, is essential for managing these conditions. However, LTCFs, particularly in rural areas, face challenges in implementing structured exercise programs due to health care professional shortages. Moreover, older adults often become bored with repetitive exercise training and may lose interest over time. The Nintendo Switch Ring Fit Adventure (RFA) exergame is a novel exergame that combines resistance, aerobic, and balance exercises and offers a potential solution by boosting motivation in an immersive manner and reducing staff intervention needs.

OBJECTIVE

We aimed to evaluate the clinical effectiveness of an exergame-based exercise training program delivered via RFA (exergame-RFA) in improving muscle mass and functional performance among older adult LTCF users.

METHODS

This was a randomized controlled trial conducted from August 2022 to September 2023 and involved older adult LTCF users (aged ≥60 y) in rural southern Taiwan. Participants were randomized into an intervention group (exergame-RFA plus standard care) or a control group (standard care alone). The intervention, conducted seated with arm fit skills and trunk control exercises using the RFA, lasted 30 minutes twice weekly over 12 weeks. The primary outcomes measured were the Study of Osteoporotic Fractures index (serving as an indicator of frailty status) and the diagnostic criteria for sarcopenia (appendicular skeletal muscle mass index, handgrip strength, and gait speed). The secondary outcomes included functional performance (box and block test as well as maximum voluntary isometric contraction of the dominant upper extremity), muscle condition (muscle thickness measured using ultrasonography), activities of daily living (Kihon checklist), health-related quality of life (Short Form Health Survey-36), and cognitive function (brain health test). We used an intention-to-treat analysis, incorporating a simple imputation technique in statistical analysis. A mixed ANOVA, with time as a within-participant factor and intervention as a between-participant factor, was used to compare the training effects on outcomes.

RESULTS

We recruited 96 individuals, of whom 60 (62%) underwent randomization. Of these 60 participants, 55 (92%) completed the study. Significant group×time interactions were observed in the intervention group in all primary outcomes (all P<.001, except P=.01 for handgrip strength) and most secondary outcomes, including maximum voluntary isometric contraction of the biceps (P=.004) and triceps brachii (P<.001) muscles, biceps muscle thickness measured using ultrasonography (P<.001), box and block test (P<.001), Kihon checklist (physical function: P=.01, mood status: P=.003, and total: P=.003), and brain health test (P<.001).

CONCLUSIONS

The exergame-RFA intervention significantly improved muscle mass, strength, and functional performance among older adult users of rural LTCFs, offering a novel approach to addressing frailty and sarcopenia.

Sustainability of exercise-induced benefits on circulating MicroRNAs and physical fitness in community-dwelling older adults: a randomized controlled trial with follow up

BACKGROUND

Circulating miRNAs (c-miR) have been shown to be potential biomarkers in sarcopenia, but the miRNAs response to aerobic exercise in older people remains inconclusive. We sought to examine the exercise benefits on physical fitness and miRNAs, and to explore the mediating effect of miRNAs on training-induced fitness changes.

METHODS

This controlled trial recruited 58 community-dwelling older adults and randomized them into exercise group (EX) and control group (CON). EX received 8-week supervised moderate intensity cycling training 3x/week. C-miR expression (c-miR-21, c-miR-126, c-miR-146a, c-miR-222), physical fitness (body composition, cardiorespiratory fitness, muscular fitness) and physical activity level (PAL, measured as in daily step counts) were evaluated at baseline, post-training, and post-16-week follow-up. The mediating effect of miRNA expression onto exercise-induced physical fitness change was determined by causal mediation analysis (CMA).

RESULTS

Exercise significantly improved body fat and cardiorespiratory fitness in older people while maintaining muscle mass and strength, and augmented expression of c-miR-126, c-miR-146a, and c-miR-222 for up to 16 weeks post-training. Notably, older people in EX had substantially higher daily step counts than CON throughout the study even after the active training period. However, CMA revealed no significant indirect effect but a potential mediating effect of c-miR-21, but not the rest, onto the body composition, cardiorespiratory fitness, and lower limb strength.

CONCLUSION

An eight-week supervised MICT program promoted a higher level of physical activity up to 16 weeks post-training, which induces better cardiorespiratory fitness and resists decline in muscular measures. C-miRNA, especially c-miR-21, potentially mediates the training effect upon fitness.

Protein-enriched soup and weekly exercise improve muscle health: A randomized trial in mid-to-old age with inadequate protein intake

BACKGROUND

Prior research has highlighted the synergistic impact of protein supplementation on muscle function post-exercise in adults; however, evidence supporting the combined effects were less robust and inconsistent on those with protein insufficiency. This investigation aims to explore efficacy of protein-enriched soup coupled with exercise on muscle health and metabolism in middle-aged and older adults with suboptimal protein intake.

METHODS

An open-label, 12-week, randomized controlled trial involving participants with insufficient protein intake (<1.0 g/kg/day) was done. The intervention group consumed protein-enriched soup (24-30 g protein daily) and 1-h weekly exercise, while controls received health education. Assessments included laboratory tests, functional assessments, and body composition.

RESULTS

In this trial, 97 out of 100 randomized participants (mean age: 64.65 ± 4.84 years, 81.8% female) completed the study (47 in intervention group and 50 in control group). Compared results of baselines, at 1 and 3 months of intervention, significant improvements in waist circumference (83.48 ± 10.22 vs. 82.5 ± 9.88 vs. 82.37 ± 9.42 cm, P for trend = 0.046), 6-min walking distance (525.65 ± 58.46 vs. 534.47 ± 51.87 vs. 552.02 ± 57.66 m, P for trend = 0.001), five-time sit-to-stand time (7.63 ± 1.63 vs. 6.81 ± 1.8 vs. 6.4 ± 1.42 s, P for trend <0.001), grip strength (26.74 ± 6.54 vs. 27.53 ± 6.99 vs. 28.52 ± 7.09 kg, P for trend <0.001), and MNA score (26.8 ± 2.14 vs. 27.73 ± 1.74 vs. 27.55 ± 1.72, P for trend <0.001) were discerned within the intervention group. The intervention demonstrated a significant reduction in serum triglyceride (105.32 ± 49.84 vs. 101.36 ± 42.58 vs. 93.43 ± 41.49 mg/dL, P for trend = 0.023), increased HDL-C (60.04 ± 16.21 vs. 60 ± 17.37 vs. 62.55 ± 18.27 mg/dL, P for trend = 0.02), and DHEA-S levels (97.11 ± 54.39 vs. 103.39 ± 56.75 vs. 106.83 ± 60.56 μg/dL, P for trend = 0.002). Serum myostatin did not differ in both groups, but serum leptin levels significantly increased (9118.88 ± 5811.68 vs. 11508.97 ± 7151.08 vs. 11220.80 ± 7190.71 pg/mL, P for trend = 0.016) in controls. The intervention group showed greater improvements in 6 min walking distance (β = 0.71, 95% CI: 6.88 to 40.79, P = 0.006), five-time sit-to-stand test (β = -0.87, 95% CI: -1.59 to -0.15, P = 0.017), MNA score (β = 0.96, 95% CI: 0.20 to 1.71, P = 0.013), serum triglycerides (β = -15.01, 95% CI: -27.83 to -2.20, P = 0.022), LDL-C (β = -9.23, 95% CI: -16.98 to -1.47, P = 0.020), and DHEA-S levels (β = 9.98, 95% CI: 0.45 to 19.51, P = 0.04) than controls.

CONCLUSIONS

Protein-enriched soup with weekly exercise over 12 weeks significantly improved physical performance, lipid profile, and DHEA-S levels among middle-aged and older adults with inadequate protein intake, while studies assessing long-term benefits of the intervention are needed.

Medium-term surgical outcomes and health-related quality of life after laparoscopic vs open colorectal cancer resection: SF-36 health survey questionnaire

BACKGROUND

Previous studies that compared the postoperative health-related quality of life (HRQoL) outcomes after receiving laparoscopic resection (LR) or open resection (OR) in patients with colorectal cancer (CRC) have different conclusions.

AIM

To explore the medium-term effect of postoperative HRQoL in such patients.

METHODS

This study randomized 567 patients undergoing non-metastatic CRC surgery managed by one surgeon to the LR or OR groups. HRQoL was assessed during the preoperative period and 3, 6, and 12 mo postoperative using a modified version of the 36-Item Short Form (SF-36) Health Survey questionnaire, emphasizing eight specific items.

RESULTS

This cohort randomly assigned 541 patients to receive LR (n = 296) or OR (n = 245) surgical procedures. More episodes of postoperative urinary tract infection (P < 0.001), wound infection (P < 0.001), and pneumonia (P = 0.048) were encountered in the OR group. The results demonstrated that the LR group subjectively gained mildly better general health (P = 0.045), moderately better physical activity (P = 0.006), and significantly better social function recovery (P = 0.0001) 3 mo postoperatively. Only the aspect of social function recovery was claimed at 6 mo, with a significant advantage in the LR group (P = 0.001). No clinical difference was found in HRQoL during the 12 mo.

CONCLUSION

Our results demonstrated that LR resulted in better outcomes, including intra-operative blood loss, surgery-related complications, course of recovery, and especially some health domains of HRQoL at least within 6 mo postoperatively. Patients should undergo LR if there is no contraindication.

Quality of Life in Patients With Pulmonary Hypertension

We explored positive and negative affect, quality of life (QOL), and associated factors in patients with pulmonary hypertension. We conducted this cross-sectional study using convenience sampling at a medical center in Taiwan. We used the Social Support Scale, positive and negative affect scale, and Short Form 36-item Health Survey to collect data. In these patients, greater social support was associated with less negative affect and better QOL (mental components). Lower Borg dyspnea scores or greater distances in the six-minute walk test were associated with more positive affect, less negative affect, and better QOL (both physical and mental components). Patients with less negative affect and more positive affect had better QOL (mental components). Therefore, nursing staff should routinely monitor the emotional status and QOL of patients with pulmonary hypertension, especially those with less social support and poorer cardiopulmonary function. Strengthening these aspects may improve patients' emotional status and QOL.

Using exergame-based exercise to prevent and postpone the loss of muscle mass, muscle strength, cognition, and functional performance among elders in rural long-term care facilities: A protocol for a randomized controlled trial

Objective

Elderly individuals in long-term care facilities (LTCFs) have a higher prevalence of sarcopenia than those in the community. Exercise is the gold standard for preventing and treating sarcopenia. Regarding exercise, multicomponent exercises, including progressive resistance training (PRT), are beneficial. However, developing routine, structured exercise programs for the elderly in LTCFs is difficult because of a shortage of healthcare providers, particularly in rural regions. Exergame-based exercises can increase a player's motivation and reduce staff time for an intervention. Nintendo Switch RingFit Adventure (RFA) is a novel exergame that combines resistance, aerobic, and balance exercises. In this study, we aim to investigate the clinical effectiveness of RFA on muscle and functional performance parameters among the elderly in LTCFs.

Methods

The EXPPLORE (using EXergame to Prevent and Postpone the LOss of muscle mass, muscle strength, and functional performance in Rural Elders) trial is a single-center randomized controlled trial involving elderly individuals (≥60 years) living in LTCFs in rural southern Taiwan. The participants will be equally randomized to the intervention group (exergame-based exercise plus standard care) or the control group (standard care alone). Both groups will receive standard care except that the intervention group will receive exergame-based exercises at the time previously scheduled for sedentary activities in the LTCFs. The exergame-based exercise will be performed using RFA in the sitting position with a specialized design, including arm fit skills and knee assist mode. Each session of the exercise lasts 30 mins and will be performed two times per week for 12 weeks. The primary outcomes will be the osteoporotic fracture index, appendicular skeletal muscle mass index, dominant handgrip strength, and gait speed. Meanwhile, the secondary outcomes will be the dexterity and agility, muscle strength and thickness, range of motion of the joints of the dominant upper extremity, Kihon checklist, Medical Outcomes Study 36-Item Short-Form Health Survey, and Brain Health Test.

Discussion

This trial will provide valuable knowledge on whether exergames using RFA can counteract physical decline and improve quality of life and cognition among the elderly in LTCFs.

Family environment characteristics and sleep duration in children: Maternal mental health as a mediator

BACKGROUND

Family environment is a key factor affecting children's health. However, little is known about whether and how the family environment affects sleep duration in children. This study investigated the effects of both physical and social characteristics of the family environment on sleep duration in children and determined whether these associations were mediated by maternal mental health.

METHODS

Data were obtained from the Taiwan Birth Cohort Study. A total of 19,400 children who completed 6-month, 18-month, 3-year, 5.5-year, and 8-year surveys were analyzed. The physical family environment characteristics were household crowding and housing quality. Family functioning was used as an indicator of family social environment. Multiple linear regression and path analysis were performed to test the hypotheses.

RESULTS

The children living in crowded households had shorter sleep durations (β = -0.03, p < .001). Superior housing quality and family functioning were associated with longer sleep durations (β = 0.04 and 0.02, respectively, ps < .01). The effects of housing quality and family functioning on sleep duration were mediated by maternal mental health.

CONCLUSIONS

Both physical and social characteristics of the family environment are critical to sleep duration in children. The effects of family environment characteristics on sleep duration in children are in part mediated by maternal mental health. Interventions to improve sleep during childhood by targeting the family environment may be more effective when maternal mental health is considered.

Predictors associated with prefrailty in older Taiwanese individuals with type 2 diabetes

Type 2 diabetes (T2DM) is one of the most well-studied and important factors that increase the risk of prefrailty in older people in Taiwan. This study was conducted to examine whether metabolic biomarkers, lifestyle behaviors, body composition, and chronic diseases are associated with frailty in older people with T2DM. We also observed how people manage their T2DM related to prefrailty. This study investigated a total of 201 participants diagnosed with T2DM who received care in our hospital from September 2018 to February 2019. Patients were divided into 3 groups (not frail, prefrail, and frail), and frailty was measured with the 5-item FRAIL scale. Socioeconomic characteristics, metabolic biomarkers, lifestyle behaviors, body composition, and chronic diseases were assessed at enrollment. No participants who we tested met the criteria for frailty. Based on the results of chi-square tests, prefrailty was associated with female sex, middle school education, unemployment, alcohol use, high body fat percentage, above-normal waist circumference, obesity, cardiovascular disease, and hypertension. Logistic regression analyses identified a significant correlation of prefrailty with the type of job from which they retired, cardiovascular disease, and hypertension. An important and surprising finding of this study was that the unemployed group was at high risk for prefrailty, which was not observed in previous research. The groups engaged in manual and professional jobs had better hand grip strength, a slower walking speed, and less risk of prefrailty than the unemployed group.

Association of Frailty With Thrombosis of Hemodialysis Vascular Access: A Prospective Taiwanese Cohort Study

RATIONALE & OBJECTIVE

Frailty, a multidimensional construct, has been associated with poor outcomes in patients receiving maintenance dialysis. This study assessed the association of frailty with dialysis vascular access patency.

STUDY DESIGN

Multicenter prospective cohort study.

SETTING & PARTICIPANTS

761 prevalent patients receiving hemodialysis at 9 centers in Taiwan as of January 2018.

EXPOSURE

Performance-based frailty was defined as 3 of the following: unintentional weight loss, weakness, exhaustion, low physical activity, and slow gait speed. Patients were categorized as prefrail if they had 1 or 2 of these characteristics.

OUTCOME

Rate of and time to dialysis access thrombosis. Data regarding vascular access events were collected for 30 months after enrollment through December 31, 2020.

ANALYTICAL APPROACH

Logistic regression analysis was used to estimate the association of clinical characteristics with frailty. Cox proportional hazards regression analysis was used to estimate the association of frailty with vascular access thrombosis adjusted for known clinical risk factors.

RESULTS

The patients' mean age was 66 years, 46% were female, 18% had synthetic graft accesses, and 82% arteriovenous fistulas. Overall, 31% were frail, 35% were prefrail, and 34% were not frail. The frailty phenotype was associated with age, female sex, low body mass index, diabetes mellitus, and prior stroke. During a median follow-up of 731 days, 161 patients (21%) had access thrombosis events (not frail, 14%; prefrail, 20%; frail, 30%; P < 0.001). Frail patients had a higher risk of vascular access thrombosis than nonfrail patients (HR, 2.31 [95% CI, 1.55-3.39], P < 0.001). After multivariable adjustment for age and comorbidities, frailty remained significantly associated with access thrombosis for both fistulas and grafts.

LIMITATIONS

Limited generalizability and potential residual confounding.

CONCLUSIONS

Frailty is associated with an increased risk of vascular access thrombosis. These findings highlight the risks of access failure experienced by frail patients receiving hemodialysis.

Better nutrition trajectory improves recovery following a hip fracture surgery for older persons with diabetes mellitus

BACKGROUND

Influences of nutritional status on hip fractured persons with diabetes mellitus (DM) following surgery have not been reported.

AIMS

To explore the trajectory groups of nutritional status and their influences on post-operative recovery for older persons with hip fracture and DM.

METHODS

A total of 169 patients with DM and hip fracture from a clinical trial were included in this analysis. Mini Nutritional Assessment was used to assess the nutritional status of the participants. Outcome variables included self-care ability, muscle strength, depressive symptoms, health related quality of life, and cognitive function, which were collected before discharge and 1-, 3-, 6-, 12-, 18-, and 24-months following hospital discharge.

RESULTS

Among hip fractured older persons with DM, within two years following surgery there were three nutritional trajectory groups: malnourished (28.3%), at-risk of malnutrition (41.9%) and well-nourished (29.8%). A decline in nutritional status, especially for the malnourished group, was seen in the second year. A better nutritional trajectory was associated with better recovery outcomes, including self-care ability, health related quality of life, cognitive function and less depressive symptoms.

DISCUSSION

Close to 30% of hip fractured persons with DM were considered to have a malnourished trajectory over 2 years following surgery. A poor nutritional trajectory was associated with poor mental health and physical recovery.

CONCLUSIONS

Continuous nutrition assessment during the first 2 years following hip fracture surgery for older persons with DM is important. Development and implementation of interventions targeting the malnourished trajectory group are suggested.

Effects of the Prolong Life With Nine Turn Method (Yan Nian Jiu Zhuan) Qigong on Brain Functional Changes in Patients With Chronic Fatigue Syndrome in Terms of Fatigue and Quality of Life

Background

Chronic fatigue syndrome (CFS) is characterized by persistent fatigue, which often leads to physical and psychological damage. The Prolong Life with Nine Turn method (PLWNT) Qigong is considered as one of the complementary treatments for improving symptoms in patients with CFS. In this study, we used functional magnetic resonance imaging (fMRI) to explore the effects of PLWNT intervention on the subjects with CFS.

Methods

Thirty four CFS patients were randomly divided into PLWNT group and cognitive behavioral therapy (CBT) group. Both groups were taught by a highly qualified professor at the Shanghai University of Traditional Chinese Medicine once a week and were supervised online during the remaining 6 days at home, over 12 consecutive weeks. We calculated the regional rs-fMRI index amplitude of low-frequency fluctuations (ALFF) for all subjects. To study the changes of the brain network, we used the brain regions with significant differences in ALFF as the regions of interest for whole-brain functional connectivity (FC) analysis. The Multi-dimensional Fatigue Inventory 20 (MFI-20) and Short Form 36-item Health Survey (SF-36) were used for clinical symptom assessment to explore the possible correlation between the rs-fMRI indicators and clinical variations.

Results

The ALFF values of the right superior frontal gyrus (SFG), and left median cingulate gyrus (DCG) were increased, whereas those of the left middle occipital gyrus (OG), right middle OG and left middle temporal gyrus (MTG) were decreased in PLWNT group. The FC values between the DCG and middle temporal gyrus (MTG), and those between the left OG and the right OG were enhanced. In addition, the SF-36 were positively with the left OG (r = 0.524), SFG (r = 0.517), and DCG (r = 0.533), MFI-20 were negatively with the SFG (r = −0.542) and DCG (r = −0.578). These results were all corrected by FWE (voxel level p &lt; 0.001, cluster level p &lt; 0.05).

Conclusion

CFS patients have abnormal regional spontaneous neuronal activity and abnormal functional connections between regions after PLWNT intervention. PLWNT can relieve the fatigue symptoms of CFS patients and improve their quality of life. The study was registered in the American Clinical Trial Registry (12/04/2018). Registration Number is NCT03496961.

Comparisons Between US Norm-based Two-component and Japanese Norm-based Three-component SF-36 Summary Scores in Systemic Lupus Erythematosus Patients

OBJECTIVE

We compared the US norm-based two-component versus Japanese norm-based three-component summary scores of the Medical Outcomes Study Short Form-36 (SF-36) in patients with systemic lupus erythematosus (SLE).

METHODS

One hundred fourteen Japanese SLE patients were studied. SF-36 physical and mental component summary (PCS and MCS) scores were computed by the US norm-based two-component and the Japanese norm-based three-component models (US2 and JP3, respectively) and compared. Their association with demographics and disease characteristics were also analyzed.

RESULTS

The US2-PCS scores were significantly higher than the JP3-PCS scores (p < 0.001); however, the US2-MCS and JP3-MCS scores were not significantly different (p = 0.16). Bland-Altman analyses demonstrated that the US2-PCS scores were generally higher than the JP3-PCS scores and their difference was larger in the subjects with lower PCS scores. However, the multiple linear regression analyses for the PCS and MCS scores computed by the different models demonstrated mostly equivalent standardized regression coefficients with the variables.

CONCLUSIONS

Although the agreement between the US norm-based two-component and Japanese norm-based three-component models of the SF-36 was insufficient, their scores demonstrated similar associations with other variables. Application of the US original version could be acceptable in certain studies depending on the research question.

Predicting Hazardous Alcohol Drinking Behaviors in Family Members of Hazardous Alcohol-Drinker Patients

Family members of hazardous or harmful alcohol drinkers suffer many consequences of their relative’s alcohol-drinking behaviors and risk developing their own hazardous alcohol drinking behaviors. Studies of alcohol-related healthcare problems have mainly focused on patients, with few studies on their family members. This cross-sectional study explored factors predicting hazardous alcohol drinking behaviors in family members of hazardous alcohol-drinker patients. Participants were recruited from four randomly chosen hospitals in Taiwan. Data were collected using self-report questionnaires on family members’ alcohol use, perceived stress, coping mechanisms, social support, health, quality of life, protective factors against hazardous alcohol drinking, facilitative factors for hazardous alcohol drinking, and demographics. The 318 family members who participated in this study were divided by their Chinese-version Alcohol Use Disorders Identification Test scores into two groups: hazardous alcohol drinkers (score ≥ 8) and non-hazardous alcohol drinkers (score < 8). Significant factors predicting hazardous alcohol drinking behaviors were found by logistic regression to be the frequency of using general coping mechanisms (OR = 1.29, p < 0.01), the frequency of using strategies to cope with patients’ drinking-related behaviors (OR = 0.89, p < 0.01), factors protecting against hazardous alcohol drinking (OR = 0.76, p < 0.01) and factors facilitating hazardous alcohol drinking (OR = 1.52, p < 0.01). Interventions should be designed for family members of hazardous alcohol drinkers to address these four significant predictors.

Health-Related Quality of Life According to Sociodemographic Characteristics in the South Korean Population

Health-related quality of life (HRQoL) concerns satisfaction with life and happiness with regard to physical, mental, and social factors. RAND-36 is a publicly available, self-administered questionnaire that examines eight health dimensions. This study evaluated the HRQoL of the South Korean population using the RAND-36 questionnaire and compared HRQoL across sociodemographic characteristics. From May 2015 to May 2019, South Koreans who visited public places aged 19−80 years were recruited and the RAND-36 questionnaire was administered. Overall, 1002 participants were recruited (mean age 45.34 years, 52% men). Men scored better than women in both physical and mental health (p < 0.05). There were significant differences in bodily pain (p < 0.05), general health perception (p < 0.05), and energy/fatigue (p < 0.05) dimensions according to the participants’ health condition. The HRQoL of South Koreans was lower than average in most dimensions compared with other countries. As the first study to assess this, its data can be used in future studies that apply RAND-36 to evaluate the HRQoL of diseased individuals, as they can compare their findings with those of our study population.

Quality of life and cognitive assessment in healthy older Asian people with early and moderate chronic kidney disease: The NAHSIT 2013–2016 and validation study

Background

Taiwan has the highest prevalence of chronic kidney disease (CKD). Impaired cognition and quality of life are significant phenomena in the late stages of CKD. We sought to obtain an overview and the attributable effect of impaired glomerular filtration on multiple domains in cognition and dimensions of quality of life for community-based healthy older adults in Taiwan.

Methods

The study was derived from the Nutrition and Health Survey in Taiwan (NAHSIT) 2013–2016, a nationwide cross-sectional study conducted to sample healthy, community-based older adults aged ≥65 years in Taiwan. Participants were categorized into four CKD groups: CKD stage 1, stage 2, stages 3a and 3b, and stages 4–5. The Mini-Mental State Examination (MMSE) and the QoL questionnaire derived from the 12-item Short Form Health Survey (SF-12) were measured. Generalized linear mixed models (GLMMs) and principal component regressions were employed for the analysis and validation, respectively.

Results

Participants with moderate CKD (stages 3a and 3b) showed deficits in global MMSE, domain orientation to time, calculation, complex commands, and role-physical and vitality in QoL questionnaires. In GLMMs, impaired eGFR per 30 mL/min/1.73 m² was associated with lower global MMSE scores (β = -0.807, standard error [SE] = 0.235, P = 0.0007), domain orientation to time (β = -0.155, SE = 0.047, P = 0.0011), calculation (β = -0.338, SE = 0.109, P = 0.0020), complex commands (β = -0.156, SE = 0.079, P = 0.0494), and role-physical (β = -2.219, SE = 0.779, P = 0.0046) dimensions of QoL.

Conclusions

Elderly Han Chinese adults with moderately impaired renal filtration could manifest cognitive deficits in orientation to time, calculation, and impaired quality of life in physical role functioning.

The Chinese Inventory of Psychosocial Balance Short-Form Questionnaire for the Older Adults: Validity and Reliability Study

BACKGROUND

Drawing from Erikson's theory, Domino and Affonso constructed the Inventory of Psychosocial Balance (IPB), a scale with satisfactory reliability and validity. However, the lack of a credible Chinese version of the scale may hinder research on ego development in Taiwan. The aim of the present study was to construct a short form Chinese IPB. In addition, factor analysis was employed to shorten the original 120-item scale to make it suitable for application in the older adults in the future.

METHODS

The study involved three steps: The first step was to establish the 120-items of the Chinese Inventory of Psychosocial Balance (C-IPB), and we conducted translation, back-translation, expert validity, and reliability of pilot study for this step. Following the first step was to construct the short-form C-IPB (CIPB-SF) in the second step, and the CIPB-SF was developed via item analysis and factor analysis. Finally, we assessed the reliability and validity of the CIPB-SF via structural equation model in the third step.

RESULTS

Three hundred eight older adults without cognitive disorder completed the IPB. The 40-item CIPB-SF was completed through item analysis and factor analysis. The internal consistency test of CIPB-SF and the eight stages were good (Cronbach's α = 0.81-0.89). The CIPB-SF had acceptable validity, except in the intimacy and identity stages, in which validity was only fair. Compared with the IPB, the CIPB-SF had good reliability and acceptable validity. However, because of its conciseness, the 40-item CIPB-SF was more suited for application among the Chinese elderly population because its application avoids physical overload.

CONCLUSION

The CIPB-SF served as a concise scale for assessing ego development in our study. This scale can also serve as a useful tool for convenient screening in the future.

Validation of the Sri Lankan Health-Related Quality-of-Life Index for pre-schoolers (SLHQL-P) and school age (SLHQL-S) children with epilepsy

INTRODUCTION

Health-related quality of life (HRQL) in children and adolescents remains an underappreciated problem in Asian region, due to lack of culturally sound HRQL measures. This paper describes the validation process of two age-specific, proxy-rated HRQL indexes namely Sri Lankan Health-Related Quality-of-Life Index for preschoolers (SLHQL-P) and school age children (SLHQL-S) with epilepsy.

METHODS

Primary caregivers of children and adolescents with epilepsy aged 1-18 years from three districts in Sri Lanka were invited to fill the SLHQL-P (for 1-5 years) and SLHQLS (for 6-18 years). It was re-administered to a subset of consenting primary caregivers after an interval of two weeks. Scientific soundness of SLHQL-P and SLHQL-S were established based on causal indicator model.

RESULTS

Total of 98 and 169 primary caregivers responded to SLHQL-P, SLHQL-S respectively. Final questionnaires of SLHQL-P and SLHQL-S consists of 26, 57 items respectively in three multi-item domains measuring the child's physical functioning (6, 9 items), psychological functioning (6, 31 items) and social functioning (14, 17 items) with higher scores reflecting better HRQL. Construct validity was established by several methods including strong relationship with seizure severity. Good test-retest reliability was also demonstrated for both SLHQL-P and SLHQL-S (r = 0.77, 0.938) CONCLUSIONS: Both SLHQL-P and SLHQL-S are feasible, reliable and valid instruments to measure HRQL in children and adolescents with epilepsy in clinical as well as research settings in Sri Lanka.

Breast Cancer Surgery 10-Year Survival Prediction by Machine Learning: A Large Prospective Cohort Study

Machine learning algorithms have proven to be effective for predicting survival after surgery, but their use for predicting 10-year survival after breast cancer surgery has not yet been discussed. This study compares the accuracy of predicting 10-year survival after breast cancer surgery in the following five models: a deep neural network (DNN), K nearest neighbor (KNN), support vector machine (SVM), naive Bayes classifier (NBC) and Cox regression (COX), and to optimize the weighting of significant predictors. The subjects recruited for this study were breast cancer patients who had received breast cancer surgery (ICD-9 cm 174-174.9) at one of three southern Taiwan medical centers during the 3-year period from June 2007, to June 2010. The registry data for the patients were randomly allocated to three datasets, one for training (n = 824), one for testing (n = 177), and one for validation (n = 177). Prediction performance comparisons revealed that all performance indices for the DNN model were significantly (p < 0.001) higher than in the other forecasting models. Notably, the best predictor of 10-year survival after breast cancer surgery was the preoperative Physical Component Summary score on the SF-36. The next best predictors were the preoperative Mental Component Summary score on the SF-36, postoperative recurrence, and tumor stage. The deep-learning DNN model is the most clinically useful method to predict and to identify risk factors for 10-year survival after breast cancer surgery. Future research should explore designs for two-level or multi-level models that provide information on the contextual effects of the risk factors on breast cancer survival.

Bone-on-Bone Contact on Radiograph is not a Prerequisite for Successful Outcome in Fixed-Bearing Medial Unicompartmental Knee Arthroplasty-A 10-Year Follow-Up Study

INTRODUCTION

 Patients without bone-on-bone osteoarthritis are excluded from mobile-bearing unicompartmental knee arthroplasty due to higher revision rates and poorer outcomes. However, we do not know if the same indication applies to fixed-bearing unicompartmental knee arthroplasty implants. Our study aims to compare functional outcomes and revision rates in patients with and without bone-on-bone arthritis undergoing fixed-bearing medial unicompartmental knee arthroplasty.

MATERIALS AND METHODS

 We reviewed 153 fixed-bearing medial unicompartmental knee arthroplasties in a single institution. Patients were divided into four groups based on joint space remaining measured on preoperative radiographs. Group 1 included knees with bone-on-bone contact; group 2 included knees with less than 2 mm joint space; group 3 included knees with 2 to 4 mm joint space; group 4 included knees with more than 4 mm joint space. Patients were followed up for 10 years postoperatively and assessed using the Oxford Knee Score, the Functional Score and Knee Score from the Knee Society Clinical Rating Score, and the Short Form 36 Health Survey.

RESULTS

 There was no difference in terms of demographic data and preoperative scores. Postoperative Knee Society Functional Score was found to be lower in group 1 as compared with the other groups. There was no difference between the four groups of patients in terms of Knee Society Knee Score, Oxford Knee Score, and Physical Component Summary and Mental Component Summary Scores from the Short Form 36 Health Survey. There was no difference in terms of survivorship free from all-cause revision at a minimum of 10 years' follow-up.

CONCLUSION

 Symptomatic patients with varying degrees of arthritis on preoperative radiographs had comparable clinical outcomes. We conclude that symptomatic patients with clinical and radiographic evidence of medial compartment osteoarthritis of any grade can benefit from a fixed-bearing medial unicompartmental knee arthroplasty.

Clinical and Economic Evaluation of Acupuncture for Opioid-Dependent Patients Receiving Methadone Maintenance Treatment: The Integrative Clinical Trial and Evidence-Based Data

Objective: From the health care and societal perspectives, this study aimed to evaluate the clinical and economic effects of acupuncture as an adjunctive therapy for patients receiving methadone maintenance treatment (MMT). Methods: We conducted a parallel-arm RCT in China in 2019. Patients were included who met the diagnostic criteria and receive MMT for more than 30 days. Patients were randomly assigned to the exposed group (acupuncture plus MMT) or control group (MMT) at a 1:1 ratio. Daily methadone dosage, drug cravings using the VAS score, and insomnia using the Pittsburgh Sleep Quality Index (PSQI) were chosen as the effectiveness indexes, and the quality-adjusted life years (QALYs) was chosen as the utility index. Results: Overall, 123 patients were included. The exposed group was significantly (P < 0.05) better than the control group in the improvement of daily methadone dosage (17.68 vs. 1.07), VAS (38.27 vs. 2.64), and PSQI (2.18 vs. 0.30). The QALY was 0.0784 (95%CI: 0.0761-0.0808) for the exposed group and 0.0762 (95%CI: 0.0738-0.0787) for the control group. The total cost of the exposed group (2869.50 CNY) was higher than the control group (2186.04 CNY). The ICER of daily methadone dosage (41.15), VAS (17.86), and PSQI (313.51) were shown to be economically efficient. While ICUR (310,663.64 CNY/QYLY) was higher than the cost suggested by WHO. Conclusion: Acupuncture as an adjuvant therapy for MMT patients realizes its cost-effectiveness by reducing the dosage of methadone, improving drug cravings, and alleviating insomnia. It helps to improve quality of life, but since its cost exceeds what society is willing to pay, further study is needed.

Serbian Translation and Validation of SF-36 for Assessment of Quality of Life in Patients with Diagnosed Arterial Hypertension

Precise estimation of life quality is of special importance in patients with chronic diseases, such as arterial hypertension. There are many questionnaires for that purpose. SF 36 with 8 domains has been proved as one of the most appropriate. To date, there was no translated and validated SF 36 in the Serbian language for hypertensive patients. The aim of this study was to test validity and reliability of the SF-36 in Serbian patients with diagnosed arterial hypertension. Cronbach’s alpha coefficient was calculated to assess the internal consistency of the Serbian version of the SF-36. After deducting the overlap between each of the 36 items and its related domain, the collective validity was considered to be good if the correlation coefficient remains > 0.4. Only 2.54% answers to the questions were missing. The values of all 8 domains were higher in men than in women. Cronbach alpha coefficient was high for the SF-36, 0.897, and it suggests that the SF-36 had good internal reliability. All 8 domains showed high values of non-rotating factorial weights (>0.300) (range from 0.742-0.856), and all measure the same thing. It means that all components in this questionnaire measure the things they are assigned to.

Adequate protein intake in older adults in the context of frailty: cross-sectional results of the Nutrition and Health Survey in Taiwan 2014-2017

BACKGROUND

Emerging evidence suggests that a dietary protein intake higher than the current recommended dietary allowance of 0.8 g/kg body weight (BW)/d may be needed to maintain optimal muscle mass, strength, and function in older adults. However, defining optimal protein intake in this age group remains a challenge.

OBJECTIVE

In this study we sought to describe the dietary protein intake in frail, prefrail, and robust older Taiwanese adults.

METHODS

Data for 1920 older adults were collected from the Nutrition and Health Survey in Taiwan from 2014 to 2017. Dietary intake was assessed using the 24-h recall method. Frailty was determined using the modified Fried's criteria. Body composition was assessed using DXA. Sex-specific dietary protein intakes, measured as values/kg of BW, fat-free mass (FFM), and lean mass (LM), were estimated for the 3 age groups (65-69, 70-79, and ≥80y) and the 3 frailty levels.

RESULTS

In both males (P for trend = 0.034) and females (P for trend = 0.015), there were significant downward trends for protein intake/kg of BW with the severity of frailty. The age-adjusted protein intake/kg of BW was still significant in males (P for trend = 0.009), but no longer in females. This phenomenon was also seen for protein intake at lunch and dinner but not at breakfast. Age-adjusted trends for protein intake/kg FFM or LM were not significant in either sex. The median protein intake in robust older males and females was 1.21 and 1.19 g/kg BW/d, respectively, and the mean intakes were even higher.

CONCLUSION

Median protein intake in robust Taiwanese older adults was approximately 1.2 g/kg BW/d, with higher mean values. The protein adequate intake in Taiwanese older adults was higher than the current recommended daily allowance (RDA) level but within the RDA range derived from the state-of art indicator amino acid oxidation technique.

Improvement in quality of life and psychological symptoms after treatment for primary aldosteronism: Asian Cohort Study

BACKGROUND

In addition to increased cardiovascular risk, patients with primary aldosteronism (PA) also suffer from impaired health-related quality of life (HRQoL) and psychological symptoms. We assessed for changes in HRQoL and depressive symptoms in a cohort of Asian patients with PA, after surgical and medical therapy.

METHODS

Thirty-four patients with PA were prospectively recruited and completed questionnaires from 2017 to 2020. HRQoL was assessed using RAND-36 and EQ-5D-3L, and depressive symptoms were assessed using Beck Depression Inventory (BDI-II) at baseline, 6 months, and 1 year post-treatment.

RESULTS

At 1 year post-treatment, significant improvement was observed in both physical and mental summative scores of RAND-36, +3.65, P = 0.023, and +3.41, P = 0.033, respectively, as well as four subscale domains (physical functioning, bodily pain, role emotional, and mental health). Significant improvement was also seen in EQ-5D dimension of anxiety/depression at 1 year post-treatment. Patients treated with surgery (n = 21) had significant improvement in EQ-5D index score post-treatment and better EQ-5D outcomes compared to the medical group (n = 13) at 1 year post-treatment. 37.9, 41.6 and 58.6% of patients had symptoms in the cognitive, affective and somatic domains of BDI-II, respectively. There was a significant improvement in the affective domain of BDI-II at 1 year post-treatment.

CONCLUSION

Both surgical and medical therapy improve HRQoL and psychological symptoms in patients with PA, with surgery providing better outcomes. This highlights the importance of early diagnosis, accurate subtyping and appropriate treatment of PA.

Culture in Cancer Survivorship Interventions for Asian Americans: A Systematic Review and Critical Analyses

Frequently hard to reach and underserved, Asian Americans are the racial group whose chief cause of mortality is cancer. Efficacious survivorship care is important, but little is known about extant intervention efforts for this community and how culture has been integrated into these efforts. This study examined cancer survivorship interventions for Asian Americans and how culture has been addressed, using an integrated framework consisting of goals, theory, methods, and cultural concordance in the persons of the interventions. Mixed methods comprising a systematic review and critical analyses were employed. Results indicate that only 13 interventions have been delivered to this community, with six of them pilot studies, and that they used a narrow range of focus on cancer type, with all interventions focusing on breast cancer survivorship. Applications of theory and methods were incongruent with cultural valuation of emotion expression and help seeking behavior. Cultural concordance was operationalized mostly as the racial ethnic match between interventionists and survivors. Deep culture factors including cultural beliefs and values were rarely specified. Theory and research should move beyond the currently prevalent definition of culture as race, ethnicity, or language, and interventions should consider the role of culture in their goals, theory, methods, and persons. Advances in theory and research are needed, as neither reliance on the Western paradigm nor assumptions about Asian Americans can be appropriate for achieving cultural validity. Future conceptualization and operationalization should consider culture more than race, ethnicity, or language.

Factors Influencing Scales of Burden, Coping Mechanisms, and Quality of Life in Caregivers of Hemodialysis Patients in Andhra Pradesh, India

Background:

Evaluation of factors influencing scales of burden, coping mechanisms, and quality of life (QOL) in caregivers of hemodialysis (HD) patients may lead to the revision of interventions aimed at the betterment of QOL of caregivers of HD patients. In this study, we investigated the influence of demographic, social, and clinical variables on burden, coping mechanisms, and QOL in caregivers of HD patients.

Methods:

In this prospective study, 150 caregivers of HD patients were recruited. Assessment of burden, coping strategies, and QOL were made by the Zarit Burden Interview, Revised Ways of Coping, and Short Form-36 QOL. The role of age, gender, and social and clinical variables on these constructs was investigated using multivariate analysis of variance.

Results:

The mean age was 43.86 ± 1.11 years. Males outnumbered females. Most were Hindu, married, primary school educated, unemployed, spouses, caring the patients, and suffering from chronic diseases for <5 years. In multivariate analysis of variance, effect of age on physical functioning (PF), general health (GH), and physical component summary (PCS) score (P < 0.01); gender on burden, distancing, seeking social support, role limitation due to emotional problem, and pain (P < 0.05); role limitations due to physical health, energy/fatigue (EF), emotional well-being, PCS, and mental component summary (MCS) score (P < 0.01); religion on PF (P < 0.05); marital status on burden and GH (P < 0.05); PF and PCS (P < 0.01); relationship of caregiver with the patient on PCS (P < 0.05); EF and MCS (P < 0.01); and presence of chronic diseases on GH and social functioning (P < 0.01) were observed.

Conclusion:

The role of demographic, social, and clinical variables should be taken into consideration while initiating therapies for reducing the burden and improving the QOL of caregivers.

The Malay version of SF-36 health survey instrument: testing data quality, scaling assumptions, reliability and validity in post-coronary artery bypass grafting (CABG) surgery patients at the National Heart Institute (Institut Jantung Negara-IJN), Kuala Lumpur

BACKGROUND

The Short Form 36 (SF-36) is a scoring system comprising of 36 items categorized into eight constructs corresponding to patients' health-related quality of life. It has been used extensively in various countries on different sub-populations and used to indicate the health status and help to ascertain the effect of clinical interventions on the particular population.

OBJECTIVE

To examine the psychometric properties of the Malay version of SF-36 (Malay SF-36) summated rating scales and validate the scale among post-coronary artery bypass grafting surgery (CABG) patients at the National Heart Institute (IJN), Kuala Lumpur.

METHODS

Five hundred and nine post-CABG patients at the IJN, Malaysia completed the questionnaires between 1 July and 31 December 2017. Psychometric tests endorsed by the "International Quality of Life Assessment Project" were utilised.

RESULTS

The data quality was excellent with a high questionnaire completion rate (100%). As hypothesized, the ordering of item means within scales was clustered. In unison, scaling assumptions were satisfied. Good discriminant validity was shown between subsets of patients with various levels of health status. Notwithstanding, there were probably translation issues of the Physical Functioning scale which showed small ceiling effects. We clearly observed high ceiling and floor effects in both Role Physical and Role Emotional scale most probably attributed to the dichotomous style of their choice of responses. Cronbach alpha values of the eight scales ranged from 0.73 to 0.90, showing good internal consistency reliability. Confirmatory Factor Analysis (CFA) confirmed the 8-factor solution and Composite Reliability revealed internal consistency reliability except for Vitality and Social Functioning. Based on the Average Variance Extracted (AVE), convergent validity was adequate except for two domains. Discriminant Validity is good for the eight constructs as the √AVE are generally higher than the correlation coefficients between the latent constructs.

CONCLUSION

The scoring for the Malay SF-36 based on the summated ratings method was proven to be valid to be applied in our local clinical population. The CFA, fitness estimates, reliability and validity assessments suggest that the Malay version of SF36 is a valid and reliable instrument. However, further work is warranted to further refine the convergent validity and reliability of some scales.

Association of health checkups with health-related quality of life among public servants: a nationwide survey in Taiwan

BACKGROUND

Preventive health checkups have gained in importance over the last decade. The association of health checkups and the number of diseases with health-related quality of life (HRQoL), including physical and mental health, remains unclear. We sought to investigate the aforementioned association among Taiwanese public servants.

METHODS

A cross-sectional survey was conducted using randomized and multistage stratified cluster sampling based on proportional probabilistic sampling. The questionnaires addressed demographics, job characteristics, health behaviors, health status, 3 types of health checkups during the preceding 3 years (government-paid health checkup [GPHC], self-paid health checkup [SPHC], and no health checkup [NOHC]), and physical component summary (PCS) and mental component summary (MCS) scores of the Short-Form Health Survey. In total 11,454 middle-aged public servants were analyzed. A multivariate general linear model (GLM) was used to estimate PCS and MCS scores by using least square means.

RESULTS

Health checkup types were associated with a significant difference in PCS scores among the public servants. Scores of PCS and MCS were both significantly higher in the GPHC group than in the NOHC group for those with no chronic diseases (51.20 vs. 50.66 [P = 0.008] and 46.23 vs. 45.58 [P = 0.02], respectively). Compared with the NOHC group, both scores of GPHC and SPHC groups were significantly associated with higher PCS scores for public servants with ≥ 2 chronic diseases (46.93 vs. 45.13 [P = 0.002] and 46.52 vs. 45.13 [P = 0.009], respectively).

CONCLUSION

In Taiwan, public servants undergoing GPHCs are more likely to report higher PCS scores than are those undergoing SPHCs. It is crucial that encourage periodically using the health checkup to improve health status and HRQoL.

Frailty Severity and Cognitive Impairment Associated with Dietary Diversity in Older Adults in Taiwan

This study aims to investigate whether frailty severity in conjunction with cognitive function, termed as” cognitive frailty”, is associated with dietary diversity in older adults. This cross-sectional study used the data from the 2014–2016 Nutrition and Health Survey in Taiwan (N = 1115; age ≥ 65 years). Dietary intake was assessed using a 24 h dietary recall and food-frequency questionnaire, and dietary diversity score (DDS; range, 0–6) and food intake frequency were calculated. The presence of frailty phenotypes was determined using the FRAIL scale, which was proposed by the International Association of Nutrition and Aging, and cognitive function was assessed using the Mini–Mental State Examination (MMSE) score. The prevalence of cognitive frailty (FRAIL scale score ≥ 3 and MMSE score ≤ 26) was 4.2%. A higher consumption frequency of dairy products, whole grains, vegetables, fruit, fish and seafood, nuts, tea, and coffee, as well as lower pickled vegetable, was inversely associated with cognitive frailty. Those with prefrailty or frailty and lower DDS demonstrated a higher cognitive impairment risk (adjust odds ratio (OR) = 2.15, 95% confidence interval = 1.21–3.83) than those without frailty and higher DDS. Older adults with cognitive prefrailty or cognitive frailty were associated with lower DDS, and frailty with lower DDS was associated with worsening cognitive function.

The Development of a Rapid Classification Scale for Sleep Quality in Community-Dwelling Older Adults - The Yilan Study, Taiwan

OBJECTIVE

Poor sleep quality is prevailing, deleterious, but heterogeneous in older adults. This study aimed to develop a simplified instrument to screen and classify poor sleep quality in community-dwelling older adults, by which stepped care with needs-based interventions could be implemented.

METHODS

Cohorts of adults aged 65 years and older were used to develop the Rapid Classification Scale for Sleep Quality (RCSSQ). Poor sleep quality was defined with the Pittsburgh Sleep Quality Index (PSQI). Established subgroups of poor sleep quality in the development dataset (n = 2622) were used as the criterion standard. Two independent validation datasets (n = 964 and 193, respectively) were used to examine the external validity. Questions in the PSQI were examined by the stepwise multinomial logistic regressions to determine the optimal numbers of items in the RCSSQ. On the premise of item parsimony and instrument validity, the optimal combination of reduced items was determined.

RESULTS

In the development dataset, the 4-item RCSSQ (RCSSQ-4) was the optimal predictive model. In terms of internal validity, the accuracy rates to identify PSQI-defined poor sleep quality and its subgroups in the developmental dataset by the RCSSQ-4 were 89.0% and 79.9%, respectively. Meanwhile, the RCSSQ-4 also had good external validity in the validation datasets to detect PSQI-defined poor sleep quality (accuracy rates: 89.1-90.7%). Furthermore, the profiles of PSQI component scores and comorbid conditions for the predicted subgroups in the validation dataset were comparable with the criterion standard.

CONCLUSION

The RCSSQ-4 is a valid instrument for screening and subgrouping poor sleep quality in community-dwelling older adults. The RCSSQ-4 may help guide tailored interventions under the context of stepped care in the community.

Effect of acupuncture for methadone maintenance treatment patients: study protocol of a randomized clinical trial

BACKGROUND

Opioid dependence is an increasing public health problem all over the world. Patients with opioid dependence have to receive methadone maintenance therapy (MMT) as replacement therapy for years or even for their entire life. Acupuncture as a kind of therapy has been used to treat substance dependence for many years. Jin's three-needle acupuncture (JTN), a type of acupuncture technique, has been applied to treat various diseases for several decades. However, JTN as an acupuncture technique has not been used to treat patients receiving MMT. Therefore, we designed a randomized controlled trial to evaluate the efficacy and safety of acupuncture as adjunctive therapy for patients receiving MMT.

METHODS/DESIGN

This study is a parallel-arm, randomized controlled trial that aims to evaluate the efficacy and safety of acupuncture as adjunctive therapy for patients receiving MMT. A total of 140 eligible participants who range in age from 18 to 60 years and fulfil the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-V), for opiate dependence will be enrolled into this study. All eligible participants will be randomly assigned to the acupuncture group or routine group in a 1:1 allocation ratio. Participants who are enrolled in the acupuncture group will receive MMT and JTN treatment for 30 min per session. Meanwhile, those who are assigned to the routine arm will receive MMT only. All 18 sessions of JTN treatment will be delivered over 6 weeks (3 per week) and followed by a 4-week follow-up period. The primary outcome measure will be the visual analogue scale (VAS) for drug craving and the daily consumption of methadone (DCOM). Secondary outcome measures will include the urine test for opioid use, the 36-item Short Form Survey (SF-36), the Beck Anxiety Inventory (BAI), the Beck Depression Inventory II (BDI-II) and Pittsburgh sleep quality index (PSQI). VAS, DCOM, BAI, BDI-II and the urine test for opioid use will be evaluated at baseline, the second week, the fourth week, the sixth week and the tenth week. SF-36 and PSQI will be assessed at baseline, the fourth week, the sixth week and the tenth week.

DISCUSSION

The results of this trial will provide evidence on the efficacy and safety of acupuncture as adjunctive therapy for patients receiving MMT.

Studying physical and mental health status among hijra, kothi and transgender community in Kolkata, India

Individuals with diverse sexual orientation and gender identities have historically experienced the major share of stigma, discrimination, and marginalization among all the LGTBIQ+ communities in India. Transgender, intersex, or queer individuals are deprived of their basic rights, self-dignity, bodily autonomy, and healthcare leading to significant negative health status. Recent legal reforms such as the decriminalization of Section 377 of the Indian Penal Code (prohibited same-sex activity) and amendments to the Transgender Persons (Protection of Rights) Bill may improve their health. In this context, the study has the following objectives: 1) to measure the physical and the mental health status of hijra, kothi, and transgender (HKT) individuals using the Short Form 12 (SF-12) questionnaire; 2) understand the variation in their health status by social determinants; and 3) identify spatial patterns of HKTs general, physical, and mental health. Data was collected using a Bengali version of SF-12 (N = 98). We calculated physical (PCS) and mental (MCS) health composite scores and conducted relevant statistical and spatial analysis. Findings revealed that HKT individuals had poor mental health (mean MCS = 42.3) compared to their physical health (mean PCS = 49.0). ANOVA tests showed statistically significant variation of PCS and MCS among HKTs by their age and income. Participants with both poor and good health conditions were evenly distributed in the study area, with no significant spatial clustering. This study was the first attempt to assess the health-related quality of life among the HKT individuals using SF-12, not previously adapted to gender-diverse communities in India. Results clearly indicate that there is a pressing need to address both physical and mental health among gender-diverse communities by not only improving awareness of their healthcare rights but by also removing social and structural barriers to health programs, increasing targeted health interventions, grassroot level activism, and government advocacy.

Satisfaction Rates Are Low following Revision Total Knee Arthroplasty in Asians Despite Improvements in Patient-Reported Outcome Measures

With the aging population in Asia and increase in total knee arthroplasty (TKA) utilization rates, the number of patients requiring revision TKA (rTKA) are expected to increase as well. The purpose of this study was to evaluate outcomes and satisfaction rates following rTKA in an Asian population that has unique cultural demands. Registry data of patients who underwent rTKA from 2006 to 2010 and had completed 5 years of follow-up were analyzed. Flexion range, Oxford Knee score (OKS), Knee Society score (KSS), the Short-Form 36 (SF-36), and satisfaction rates were assessed for improvement from preoperative values, as well as by the minimum clinically important difference (MCID) criterion. rTKA was performed in 163 patients. There were significant improvements seen at 2 years postoperatively and these were sustained up to 5 years. The minimal clinically important difference (MCID) criterion for KSS, OKS, and SF-36 physical component score (PCS) was met at 2 and 5 years postoperatively. The overall complication rate was 3.7% at a mean follow-up of 8.4 years. A total of 121 patients (74.2%) were satisfied at 5 years postoperatively. Within our cohort, rTKA results in significantly improved patient-reported outcome measures with a low complication rate of 3.7% at a minimum of 5-year follow-up. Despite these encouraging results, satisfaction rates remain low.

Efficacy of Electroacupuncture Combined with Auricular Point Pressing in Improving Mental Well-Being among Individuals with Heroin Use Disorder: A Randomized Controlled Crossover Trial and Pilot Study

Objective

To evaluate the clinical efficacy of combining electroacupuncture with auricular point pressing in improving quality of life of individuals with heroin use disorder undergoing methadone maintenance treatment.

Design

A randomized controlled crossover trial.

Subjects

50 participants were recruited from Taipei City Hospital, Linsen Chinese Medicine and Kunming branches, and randomly allocated to treatment groups.

Method

The 36-Item Short Form Health Survey (SF-36) was used. Group A received electroacupuncture at the Hegu (LI4) and Zusanli (ST36) and auricular point pressing on Ear Shenmen, and Group B received only auricular point pressing on Ear Shenmen biweekly for 4 weeks. After a 1-week washout period, crossover of the groups was performed.

Results

The SF-36 mental component scores of the combined treatment group improved relative to the single treatment group (11.09 vs. 10.33, p=0.023). Methadone dosage was reduced in both groups (combined therapy group: 8.58 ± 4.17/7.76 ± 4.11 (baseline/posttreatment) vs. single therapy group: 8.36 ± 4.20/8.30 ± .28, p=0.001).

Conclusion

Combined therapy of high-frequency electroacupuncture with auricular point pressing had better efficacy in enhancing quality of life, especially for mental well-being, and in gradually reducing methadone dosage.

Translation and Validation of the Malay Version of Comprehensive Geriatric Assessment Questionnaire for Older Adults in Malaysia

Background

This study aimed to translate and validate the comprehensive geriatric assessment (CGA) questionnaire among older adult patients in Malaysia in the Malay language.

Methods

The questionnaire contained items on the socio-demographic characteristics, medical condition, quality of life (QOL), nutritional status, functional capacity, and depression status. The forward and backward translation processes of the original English language version of the questionnaire were undertaken by three independent linguistic translators, while its content was validated by an expert team consisting of seven geriatricians, physicians, dietitian, and lecturers. The Malay version of the questionnaire was tested for face validity in 10 older adult patients over 65 years of age. The internal consistency reliability and construct validity were evaluated among 166 older adult patients (mean age, 71.0 years; 73.5% male). The questionnaire was administered through face-to-face interviews with the patients. Minor amendments were made after the content and face validity tests.

Results

The internal consistency reliability was good, as the Cronbach’s alpha for most of the scales surpassed 0.70, ranging from 0.70 to 0.98, with only one exception (Mini Nutritional Assessment Short-Form, Cronbach’s alpha=0.62). The factor loadings for all scales were satisfactory (>0.40), ranging from 0.45 to 0.90.

Conclusion

The Malay-version CGA showed evidence of satisfactory internal consistency reliability and construct validity in Malaysian geriatric patients.

Verification of the Reliability and Validity of the Short Form 36 Scale in Indonesian Middle-aged and Older Adults

Objectives

The Short Form 36 (SF-36) questionnaire is increasingly being used to measure health-related quality of life (HRQoL) in Indonesia. However, evidence that it is valid for use in Indonesian adults is lacking. This study assessed the validity and reliability of the SF-36 in Indonesian middle-aged and older adults.

Methods

Adults aged 46-81 years (n=206) in Yogyakarta, Indonesia completed the SF-36, another measure of HRQoL (the EuroQoL visual analogue scale [EQ-VAS]), and measures assessing their demographic characteristics. Fifty-four percent (n=121) completed the SF-36 measure again 1 week later. Confirmatory factor analysis was conducted to confirm the factor structure of the SF-36. Internal consistency reliability was estimated using Cronbach’s alpha, and test-retest reliability was assessed using intraclass correlations. Convergent and discriminant validity were assessed by computing correlations among SF-36 subscales, between subscales and the 2 component scores, and between component scores and EQ-VAS scores.

Results

Most scaling assumptions were met. The hypothetical factor structure fit the data poorly (root mean square error of approximation [RMSEA]=0.108) and modification was required for a good fit (RMSEA=0.060). Scores on all subscales demonstrated acceptable internal consistency (α>0.70) and test-retest reliability (r>0.70). Divergent validity was supported by weak to moderate interscale correlations (r=0.19 to 0.64). As expected, the 2 summary scores were moderately to strongly correlated with the EQ-VAS (r>0.60).

Conclusions

The findings adequately support the use of SF-36 in Indonesian middle-aged and older adults, although the optimal algorithm for computing component scores in Indonesia warrants further investigation.

Health related quality of life in adult primary Ciliary dyskinesia patients in Cyprus: development and validation of the Greek version of the QOL-PCD questionnaire

BACKGROUND

The QOL-PCD questionnaire is a recently developed Health Related Quality of Life (HRQoL) instrument for Primary Ciliary Dyskinesia. The aim of this study was to translate the adult QOL-PCD questionnaire into Greek language and to conduct psychometric validation to assess its performance.

METHODS

Forward translations to Greek and backward translation to English were performed, followed by cognitive interviews in 12 adult PCD patients. The finalized translated version was administered to a consecutive sample of 31 adult, Greek speaking PCD patients in Cyprus for psychometric validation, which included assessment of internal consistency, test-retest reliability, construct and convergent validity. Internal consistency was assessed by Cronbach's alpha test in terms of the overall and sub-scales. Test-retest reliability was assessed by repeat administration of the questionnaire within 2 weeks and calculation of the intra-class correlation (ICC). Construct validity was assessed by comparing different groups of patients based on a-priori hypotheses and convergent validity was evaluated by examining associations between the QOL-PCD and SF-36 questionnaires.

RESULTS

Moderate to good internal consistency was observed (Cronbach's α: 0.46-0.88 across sub-scales) and test-retest reliability assessment demonstrated good repeatability for most scales (ICC: 0.67-0.91 across subscales). Patients of female gender, older age and lower lung function exhibited lower QOL-PCD scores in general, while high correlations for most QOL-PCD scales with corresponding SF-36 scales were observed, in particular for physical functioning (r = 0.78, p < 0.05).

CONCLUSION

The adult version of QoL-PCD questionnaire has been translated according to international guidelines resulting to a cross-culturally validated Greek version which exhibited moderate to good metric properties in terms of internal consistency, stability, known-group and convergent validity.

Subgrouping Poor Sleep Quality in Community-Dwelling Older Adults with Latent Class Analysis - The Yilan Study, Taiwan

The manifestation of older adults with poor sleep quality is heterogeneous. Using data-driven classifying methods, the study aims to subgroup community-dwelling older adults with poor sleep quality. Adults aged 65 and older participated in the Yilan study. Poor sleep quality was defined using the Pittsburgh Sleep Quality Index. Latent class analysis with the 7 subscores of the Pittsburgh Sleep Quality Index as the indicators was used to generate empirical subgroups. Differences in comorbidity patterns between subgroups were compared. A total of 2622 individuals, of which 1011 (38.6%) had Pittsburgh Sleep Quality Index -defined poor sleep quality, participated. Three groups for poor sleep quality were specified in the latent class analysis: High Insomnia (n = 191, 7.3%), Mild Insomnia (n = 574, 21.9%), and High Hypnotics (n = 246, 9.4%). The High Insomnia and Mild Insomnia groups shared similar profiles but different severities in the 7 domains of the Pittsburgh Sleep Quality Index. In contrast, the High Hypnotics group had the lowest Pittsburgh Sleep Quality Index total scores and insomnia severity but had similar mental and physical comorbid patterns as the High Insomnia group. This finding suggests that poor sleep quality in community-dwelling older adults had various feature-based subgroups. It also implicates the development of group-centered interventions.

Quality of Sleep and Psychosocial Factors for Patients Undergoing Peritoneal Dialysis

Objectives

Sleep disorders are common in end-stage renal disease patients. This study examined the relationship between self-reported quality of sleep (QoS) and certain psychosocial domains for patients on peritoneal dialysis (PD).

Methods

The study subjects included 190 PD patients from 7 urban dialysis clinics in Northern Taiwan, from whom we obtained biochemical parameters and demographic data. QoS, quality of life (QoL), religious/spiritual activity, and depression were assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire, Medical Outcomes Study Short Form (SF-36) for QoL, the Royal Free Questionnaire, and the Beck Depression Inventory, respectively.

Results

The average PSQI score was 9.1 ± 4.1 and, in total, 85.8% of all patients were poor sleepers (global PSQI ≥ 5). There was no difference in age, gender, and mode or duration of PD between good and poor sleepers. Biochemical data did not differ between the two groups. Widowed patients experienced significantly poorer QoS than patients with other marital status (PSQI scores: 12.3 ± 4.9 vs 8.88 ± 4.0, p = 0.006). The percentage of patients that held a bachelor's degree or above was significantly higher in good sleepers (55.6% vs 29.4%, p = 0.008). The PSQI value correlated negatively with the QoL scale in both physical ( r = –0.295, p < 0.001) and mental domains ( r = –0.410, p < 0.001), and correlated positively with the depression scale ( r = 0.351, p < 0.001). There appeared to be no association between QoS and spiritual/religious activity ( r = –0.097, p = 0.223).

Conclusions

Psychosocial factors including depression, patients’ perceptions regarding QoL, marital status, and educational background correlated significantly to the subjective QoS for PD patients. When dealing with sleep disorders in PD patients, physicians should pay considerable attention to their psychosocial backgrounds.

Developing item banks to measure three important domains of health-related quality of life (HRQOL) in Singapore

Objectives

To develop separate item banks for three health domains of health-related quality of life (HRQOL) ranked as important by Singaporeans – physical functioning, social relationships, and positive mindset.

Methods

We adapted the Patient Reported Outcomes Measurement Information System Qualitative Item Review protocol, with input and endorsement from laymen and experts from various relevant fields. Items were generated from 3 sources: 1) thematic analysis of focus groups and in-depth interviews for framework (n = 134 participants) and item(n = 52 participants) development, 2) instruments identified from a literature search (PubMed) of studies that developed or validated a HRQOL instrument among adults in Singapore, 3) a priori identified instruments of particular relevance. Items from these three sources were “binned” and “winnowed” by two independent reviewers, blinded to the source of the items, who harmonized their selections to generate a list of candidate items (each item representing a subdomain). Panels with lay and expert representation, convened separately for each domain, reviewed the face and content validity of these candidate items and provided inputs for item revision. The revised items were further refined in cognitive interviews.

Results

Items from our qualitative studies (51 physical functioning, 44 social relationships, and 38 positive mindset), the literature review (36 instruments from 161 citations), and three a priori identified instruments, underwent binning, winnowing, expert panel review, and cognitive interview. This resulted in 160 candidate items (61 physical functioning, 51 social relationships, and 48 positive mindset).

Conclusions

We developed item banks for three important health domains in Singapore using inputs from potential end-users and the published literature. The next steps are to calibrate the item banks, develop computerized adaptive tests (CATs) using the calibrated items, and evaluate the validity of test scores when these item banks are administered adaptively.

Health-Related Quality of Life of Medical Students in a Chinese University: A Cross-Sectional Study

Thus far, there have been no studies adapting the Mandarin 36-Item Short Form Health Survey (the SF-36) questionnaire for assessment of the health-related quality of life (HRQOL) of medical students in China. This study aimed to explore the feasibility of that form and analyse its impact factors. The study involved 498 randomly sampled medical students stratified by their academic majors, and general information was collected. The effective response rate was 83.53%. Split-half reliability coefficients and Cronbach's α coefficients of seven dimensions were more than 0.7 with the exception of the social function (SF) dimension. Spearman's correlation analysis results were basically in accord with the theoretical construction of the SF-36. The HRQOL of the students was scored from 43.83 (the RE dimension) to 93.34 (the PF dimension). The primary impact factors affecting the HRQOL of medical students included major, sleep quality, degree of physical exercise, post-exercise status, relationship with roommate, and satisfaction with family. These findings suggested that the Mandarin SF-36 was reliable for measuring the HRQOL, that the HRQOL of medical students in a Chinese university was relatively poor, and that its improvement requires concerted efforts.

Gender differences and burden of chronic conditions: impact on quality of life among the elderly in Taiwan

BACKGROUND

Multiple chronic conditions affect people's health-related quality of life (QoL) and the distributions of the conditions may differ between genders. Our goal was to examine gender differences in chronic conditions and QoL among community-living elderly in Taiwan and to examine whether differences in QoL between genders, if present, were attributable to the distribution of chronic conditions.

METHODS

We used data from the Nutrition and Health Survey in Taiwan (NAHSIT, 2005-2008), which interviewed a representative sample of the Taiwanese population. The survey questions included the SF-36 questionnaire to assess participants' QoL and items for participants' medical history. We used multiple linear regressions to examine the difference in QoL between genders.

RESULTS

We included 1179 elders for our analysis; men accounted for 52% (612/1179). The mean age was 73; women were slightly younger. The mean (standard deviation) of SF-36 physical and mental health component score (PCS and MCS) was 44.5 (11.1) and 55.6 (9.0), respectively, and women reported a significantly lower PCS than men (difference - 4.85, p < 0.001). Urinary incontinence, arthritis, stroke, and kidney disease were associated with a clinically meaningful decrease in PCS (≤ - 6.5 points). The difference in PCS between genders was not attenuated after we accounted for chronic conditions in regression analysis.

CONCLUSIONS

Our findings suggest that women tend to report that their physical health-related QoL is poorer than that of men, and such a difference does not seem to be attributable to the distribution of chronic conditions. Elderly men and women may perceive health-related QoL differently.

Patient-Reported Outcome Measures for Toe-to-Hand Transfer: A Prospective Longitudinal Study

BACKGROUND

Patient-reported outcome measures are an important metric in evaluating treatment efficacy of reconstructive surgery. Toe-to-hand transfer can restore vital prehensile function; however, this surgery is complex, extensive rehabilitation is required, and there are concerns about donor-site morbidity. This study longitudinally explores the benefits of this procedure, from the patient's perspective, using patient-reported outcome measures.

METHODS

Twenty-three patients who underwent free toe-to-hand transfers from 2012 to 2015 were evaluated preoperatively and postoperatively using the following validated questionnaires: the Michigan Hand Outcomes Questionnaire, the 36-Item Short-Form Health Survey, and the Lower Limb Outcomes Questionnaire. Subgroup analysis was performed between dominant and nondominant reconstructed hands.

RESULTS

Mechanism of injury was crush in 83 percent; the remainder sustained cutting, avulsion, and burn injuries. Thirty-four toes were transferred: nine great toes, 20 second toes, and five third toes. Michigan Hand Outcomes Questionnaire results showed significant improvement in overall activities of daily living, work, aesthetics, and patient satisfaction (p < 0.05). The results of the 36-Item Short-Form Health Survey showed significant improvements in physical and emotional roles (p < 0.05). The Lower Limb Outcomes Questionnaire showed no deterioration of foot function (p = 0.55). Subgroup analysis showed significant improvement in patient-reported outcome measures for patients undergoing dominant hand reconstruction but no difference between thumb reconstruction and finger-only reconstruction.

CONCLUSIONS

Patient-reported outcome measures demonstrate the significant utility of toe-to-hand transfer procedures in both functional and psychosocial domains in that there are relatively greater benefits in reconstructing the dominant hand, and that donor-site morbidity is well tolerated.

Characteristics of Burden, Coping Strategies, and Quality of Life: The Effect of Age, Gender, and Social Variables in Caregivers of Renal Transplanted Patients from Southern Andhra Pradesh, India

Background:

Evaluation of burden, coping strategies, and quality of life (QOL) in caregivers may lead to specific interventions to reduce the burden among caregivers.

Methods:

In this prospective study, characteristics of burden, coping strategies, and QOL in caregivers was investigated and also studied the effect of age, gender, and social variables on these concepts.

Results:

Mean burden score of the caregivers was 28.66 ± 2.02. Thirty percent of caregivers had mild-to-moderate burden followed by moderate-to-severe burden (20%). Seeking social support was the dominant coping strategy used by the caregivers. Role limitations due to the physical health (RLDPH) and role limitations due to emotional problem (RLDEP) were compromised subscales of QOL. The mean score of RLDPH (P = 0.007) and RLDEP (P = 0.014) were found to be significantly higher in males than that of females. Marital status, education, type of relationship with the patient, religion, occupation, and duration of care giving showed significant effect on burden, coping strategies, and QOL. Lower emotional well-being (P = 0.003) and escape avoidance (P = 0.000) in males and lower physical component (PC) (P = 0.002) in females and lower PC (P = 0.000) and escape avoidance (P = 0.001) were found to be the significant predictors of burden in caregivers of renal transplanted patients.

Conclusion:

Predictors of burden and QOL subscales varies by gender. Social and clinical variables influence the QOL subscales. Gender- and social group-specific interventions rather than global interventions may reduce the burden of caregivers.

Burden, coping mechanisms, and quality of life among caregivers of hemodialysis and peritoneal dialysis undergoing and renal transplant patients

CONTEXT

Investigations on burden, coping, and quality of life (QOL) in caregivers of hemodialysis (HD) and peritoneal dialysis (PD) undergoing and renal transplant (RT) patients may lead to the well-being of caregivers, and these studies are sparse and nil in Indian context.

AIM

This study aims to comparatively evaluate the burden, coping mechanisms, and QOL among caregivers of HD and PD undergoing and RT patients.

SETTING AND DESIGN

Tertiary care hospital, cross-sectional and descriptive study.

SUBJECTS AND METHODS

Burden, coping mechanisms, and QOL in caregivers of HD and PD undergoing and RT patients were investigated using Zarit burden interview, revised ways of coping and short-form 36 in 30 each caregivers of HD and PD undergoing and RT patients.

RESULTS

Moderate to severe burden, mild to moderate burden, and no burden were observed in the majority of caregivers of HD and PD undergoing and RT patients. Significantly higher mean burden score in caregivers of HD undergoing than RT patients (P < 0.01); accepting responsibility in caregivers of RT than PD undergoing patients; social functioning in caregivers of HD than PD undergoing patients; and general health in caregivers of RT than HD undergoing patients, was observed. Lower physical component was common in each group, whereas accepting responsibility in HD, self-controlling in PD, and age and escape avoidance in RT were found to be the specific predictors of the burden score.

CONCLUSIONS

Caregivers of HD and PD undergoing and RT patients have different levels of burden, use different mechanisms to cope, and showed different predictors of burden score.

Interactions of BDNF Val66Met Polymorphism and Menstrual Pain on Brain Complexity

The irregularity and uncertainty of neurophysiologic signals across different time scales can be regarded as neural complexity, which is related to the adaptability of the nervous system and the information processing between neurons. We recently reported general loss of brain complexity, as measured by multiscale sample entropy (MSE), at pain-related regions in females with primary dysmenorrhea (PDM). However, it is unclear whether this loss of brain complexity is associated with inter-subject genetic variations. Brain-derived neurotrophic factor (BDNF) is a widely expressed neurotrophin in the brain and is crucial to neural plasticity. The BDNF Val66Met single-nucleotide polymorphism (SNP) is associated with mood, stress, and pain conditions. Therefore, we aimed to examine the interactions of BDNF Val66Met polymorphism and long-term menstrual pain experience on brain complexity. We genotyped BDNF Val66Met SNP in 80 PDM females (20 Val/Val, 31 Val/Met, 29 Met/Met) and 76 healthy female controls (25 Val/Val, 36 Val/Met, 15 Met/Met). MSE analysis was applied to neural source activity estimated from resting-state magnetoencephalography (MEG) signals during pain-free state. We found that brain complexity alterations were associated with the interactions of BDNF Val66Met polymorphism and menstrual pain experience. In healthy female controls, Met carriers (Val/Met and Met/Met) demonstrated lower brain complexity than Val/Val homozygotes in extensive brain regions, suggesting a possible protective role of Val/Val homozygosity in brain complexity. However, after experiencing long-term menstrual pain, the complexity differences between different genotypes in healthy controls were greatly diminished in PDM females, especially in the limbic system, including the hippocampus and amygdala. Our results suggest that pain experience preponderantly affects the effect of BDNF Val66Met polymorphism on brain complexity. The results of the present study also highlight the potential utilization of resting-state brain complexity for the development of new therapeutic strategies in patients with chronic pain.

Comparison of Models for Predicting Quality of Life After Surgical Resection of Hepatocellular Carcinoma: a Prospective Study

BACKGROUND

The essential issue of internal validity has not been adequately addressed in prediction models such as artificial neural network (ANN), support vector machine (SVM), Gaussian process regression (GPR), and multiple linear regression (MLR) models.

METHODS

This prospective study compared the accuracy of these four models in predicting quality of life (QOL) after hepatic resection received by 332 patients with hepatocellular carcinoma (HCC) during 2012-2015. An estimation subset was used to train the models, and a validation subset was used to evaluate their performance. Sensitivity score approach was also used to assess the relative significance of input parameters in the system models.

RESULTS

The ANN model had significantly higher performance indicators compared to the SVM, GPR, and MLR models (P < 0.05). Additionally, the ANN prediction of QOL at 6 months after hepatic resection significantly correlated with age, gender, marital status, Charlson comorbidity index (CCI) score, chemotherapy, radiotherapy, hospital volume, surgeon volume, and preoperational functional status (P < 0.05). Preoperational functional status was the most influential (sensitive) variable affecting sixth-month QOL followed by surgeon volume, hospital volume, age, and CCI score.

CONCLUSIONS

The comparisons showed that, in preoperative and postoperative healthcare consultations with HCC surgery candidates, QOL at 6 months post-surgery should be estimated with an ANN model rather than with SVM, GPR, or MLR models. The best QOL predictors identified in this study can also be used to educate candidates for HCC surgery in the expected course of recovery and other surgical outcomes.

Enoch Senior's College for Korean Immigrant Seniors: Quality of Life Effects

ABSTRACTA community-based program is increasingly recognized as promoting health and active social participation in one's life, yet information is lacking about the use and impact of such programs among immigrant visible minority seniors. This mixed-method research evaluated the impact of a cultural community program for Korean immigrant seniors by examining participants' health-related quality of life (HR-QOL) benefits and overall well-being. In this study, 79 participants completed the SF-36v2 questionnaire twice to assess the impact of Canada Enoch Senior's College (CESC) program on their HR-QOL and well-being. Statistically significant improvement in physical and mental health domains was observed: bodily pain and role limitations due to emotional problems. Qualitative data from participants' interviews supported the survey findings with positive contributions in health and social arenas of seniors' lives. These results suggest that the CESC program contributes to quality of life and well-being of Korean senior participants and supports similar community-based cultural programs.
