PURPOSE: The purpose of this study was to test the reliability and validity of the Behavior Assessment for Children (BAC) in a community of school-aged children in Taiwan. METHOD: A school-based sample comprising third grade and fourth grade students was recruited from Taichung City in Taiwan. The parents (n = 248) and teachers (n = 15) of these students completed structured questionnaires, including the Child Behavior Checklist (CBCL) and the proposed BAC. Content validity, concurrent validity, construct validity, internal consistency, and inter-rater reliability of the BAC were assessed. RESULTS: The BAC comprised three subscales (attention, emotion, and self-control) that included 17 items. The content validity index (CVI) score was 0.98. The result of the confirmatory factor analysis (goodness of fit = .90, root mean square of residual = .03, root mean square error of approximation = .06, and comparative fit index = .94) supported the construct validity of the three BAC subscales. The concurrent validity of the BAC subscales significantly correlated with the compatible CBCL subscales (r = .59-.78, p < .001). Cronbach α of the subscales of the BAC ranged from .78 to .92. The intraclass correlation coefficient between the parents and teachers ranged from .31 to .44, and the joint probability of agreement ranged from 31.4% to 92.2%. CONCLUSIONS: The BAC is a valid and reliable instrument for evaluating behavioral problems in schoolaged children.

Purpose: We examined the self-care experiences of adolescents with spinal muscle atrophy (SMA) and their perceptions of the interactions between their body and the environment. Methods: We interviewed ten adolescents with SMA aged 13–18 years regarding personal care practices. Purposive sampling was conducted in two medical centers in northern Taiwan. Data were analyzed using the Giorgi analysis method. Results: Four constitutions were identified: (1) limited space for independent development, (2) multiple reconstructions of self-image to improve physical ability, (3) self-care of disease, and (4) developing activity styles to accommodate social culture. Conclusion The self-care lived experiences of patients reflect dynamic changes in the body and environment. Self-existence was exhibited by adjustment, practice, and creativity of physical activity to integrate into society. Nursing staff should understand the self-care experiences and needs of adolescents with SMA to develop a database of self-care skills. This study recommended that nursing staff improve their ability to guide patients in taking care of themselves by developing body awareness self-care courses and individual care plans in response to various stages of disability to help patients delay deterioration, realize their physical potential, and promote independence and social development.

PURPOSE: At present, there is still controversy between parents of children with muscular dystrophy (MD) and health-care professionals on care issues. Partnerships can connect the affected children and their families to appropriate health-care services, to jointly face the care environment together and thereby improve the quality of life of children with MD. Therefore, the objective of this study was to explore partnerships between families and health-care professionals from the perspectives of parents of children with MD. METHODS: Husserl's phenomenological research was applied to explore the basic structures of parents' descriptions of MD. Through purposive sampling, we conducted in-depth interviews with parents, and analyzed the data according to the theory of Giorgi. Nineteen parents (10 mothers, 9 fathers) participated in this study. The precision of the research results was tested by applying the four standards of Lincoln and Guba. RESULTS: This study identified five constituents: feasible resources and detailed care information; the provision of an integrated medical care across systems; family and home as key elements in critical care; respect and care for family care demands; and finally, feedback and support from families. CONCLUSION: This study demonstrated that partnerships were established by health-care professionals, enhancing the care capacity of the families, developing the preventive medicine of MD, and enhancing children's potential for self-care within the families. Hospital policies should include the promotion of family partnership care. The findings can help health-care professionals recognize the life experiences of children with MD when providing medical care.

INTRODUCTIONConstipation is a common poststroke complication. This study was designed to document the incidence and clinical course of poststroke constipation in a rehabilitation ward, as well as identify the factors independently associated with the condition.

METHODSThis retrospective study involved patients who were admitted to the rehabilitation ward of our institute due to an acute stroke between 1 August 2010 and 31 July 2011. The main outcome measured was the incidence of poststroke constipation, defined as the use of laxative after stroke, fulfilment of the Rome II diagnostic criteria for functional constipation and/or stool impaction. The variables examined were basic demographic data, presence of impairment, degree of disability (evaluated using the Barthel index), walking ability, medications taken and medical complications.

RESULTSOut of the 155 patients who met the inclusion criteria, 123 (79.4%) had poststroke constipation. All 123 patients used oral laxatives; 56 received additional rectal medications and 13 discontinued their use of laxatives at discharge. Patients with poststroke constipation were more likely to have major medical complications (p = 0.04). Those who used rectal medications had a higher risk of major medical complications than those who used only oral laxatives (p < 0.01). Infratentorial lesions were an independent predictor of poststroke constipation (p = 0.003). More severe disability increased the severity of constipation, as indicated by the use of rectal medication.

CONCLUSIONPoststroke constipation is a common complication during inpatient rehabilitation. Healthcare providers should be aware of the incidence of poststroke constipation. Further studies are required to establish standard guidelines for screening and managing bowel function in patients with stroke.

Objective: Problematic use of social media (PUSM) may affect sleep quality and self-stigma in people with schizophrenia and consequently reduce their quality of life (QoL). This longitudinal study investigated if sleep quality and self-stigma mediated relationships between PUSM and QoL. Methods: One-hundred-and-ninety-three outpatients with schizophrenia were recruited from a psychiatric center in Taiwan from April 2019 to August 2021 and participated in a longitudinal study at intervals of three months between measurements. QoL was assessed using the World Health Organization Quality of Life Questionnaire Brief Version; sleep quality using the Pittsburgh Sleep Quality Index; self-stigma using the Self-Stigma Scale-Short; and PUSM using the Bergen Social Media Addiction Scale. Via SPSS 20.0, general estimating equation models assessed temporal associations between variables. Via R software, mediating effects of self-stigma and sleep quality were examined through Monte Carlo simulations with 20,000 repetitions. Results: Mean scores of physical, psychological, social and environmental QoL ranged from 11.86 to 13.02. Mean scores of sleep quality and self-stigma were 9.1±4.5 and 2.2±0.8, respectively. Sleep quality and self-stigma were directly related to QoL (p<0.001) and mediated indirect relationships between PUSM and all components of QoL with a range of 95% confidence intervals spanning from -0.0591 to -0.0107 for physical QoL; -0.0564 to -0.0095 for psychological QoL; -0.0292 to -0.0035 for social QoL; and -0.0357 to -0.0052 for environmental QoL. Conclusion Sleep quality and self-stigma mediated relationships between PUSM and QoL in people with schizophrenia. Developing interventions targeting PUSM, sleep, and self-stigma may help improve QoL in people with schizophrenia.

Varus deformation in knee joint is one of the common symptoms caused by unicompartment knee osteoarthritis. Currently, several operations can be used for correcting such deformation, including high tibial osteotomy, unicondylar knee arthroplasty (UKA) and fibulectomy. UKA has been developed for over 60 years, with the advantage of normal knee kinematics restored, less incision, more bony tissue preserved and larger range of motion than total knee arthroplasty (TKA). Therefore, UKA has become a reliable method for treating unicompartment knee osteoarthritis. Fibulectomy is a new kind of surgical technique for treating varus deformation in knee joint, with the advantage of simple operation, low cost and fast recovery. At present, fibulectomy has been widely applied, but its treatment mechanism is still not clear. In this review, two clinical operations UKA and fibulectomy were summarized, and the possible mechanism of fibulectomy for treating unicompartment knee osteoarthritis was proposed from the viewpoint of biomechanics. The author hypothesized that reduction in lateral muscle force after fibulectomy would cause rebalance of the resultant joint moment, therefore, the change of joint contact position and the decrease in joint contact force might be the cause of fibulectomy to release the pain for knee osteoarthritis patients.

Background/Aims: Obstacles exist in facilitating hepatitis C virus (HCV) care cascade. To increase timely and accurate diagnosis, disease awareness and accessibility, in-hospital HCV reflex testing followed by automatic appointments and a late call-back strategy (R.N.A. model) was applied. We aimed to compare the HCV treatment rate of patients treated with this strategy compared to those without. Methods: One hundred and twenty-five anti-HCV seropositive patients who adopted the R.N.A. model in 2020 and another 1,396 controls treated in 2019 were enrolled to compare the gaps in accurate HCV RNA diagnosis to final treatment allocation. Results: The HCV RNA testing rate was significantly higher in patients who received reflex testing than in those without reflex testing (100% vs. 84.8%, P<0.001). When patients were stratified according to the referring outpatient department, a significant improvement in the HCV RNA testing rate was particularly noted in patients from non-hepatology departments (100% vs. 23.3%, P<0.001). The treatment rate in HCV RNA seropositive patients was 83% (83/100) after the adoption of the R.N.A. model, among whom 96.1% and 73.9% of patients were from the hepatology and non-hepatology departments, respectively. Compared to subjects without R.N.A. model application, a significant improvement in the treatment rate was observed for patients from non-hepatology departments (73.9% vs. 27.8%, P=0.001). The application of the R.N.A. model significantly increased the in-hospital HCV treatment uptake from 6.4% to 73.9% for patients from non-hepatology departments (P<0.001). Conclusions The care cascade increased the treatment uptake and set up a model for enhancing in-hospital HCV elimination.

The bone remodeling process in response to orthodontic forces requires the activity of osteoclasts to allow teeth to move in the direction of the force applied. Receptor activator of nuclear factor-κB ligand (RANKL) is essential for this process although its cellular source in response to orthodontic forces has not been determined. Orthodontic tooth movement is considered to be an aseptic inflammatory process that is stimulated by leukocytes including T and B lymphocytes which are presumed to stimulate bone resorption. We determined whether periodontal ligament and bone lining cells were an essential source of RANKL by tamoxifen induced deletion of RANKL in which Cre recombinase was driven by a 3.2 kb reporter element of the Col1α1 gene in experimental mice (Col1α1.CreER.RANKL) and compared results with littermate controls (Col1α1.CreER.RANKL). By examination of Col1α1.CreER.ROSA26 reporter mice we showed tissue specificity of tamoxifen induced Cre recombinase predominantly in the periodontal ligament and bone lining cells. Surprisingly we found that most of the orthodontic tooth movement and formation of osteoclasts was blocked in the experimental mice, which also had a reduced periodontal ligament space. Thus, we demonstrate for the first time that RANKL produced by periodontal ligament and bone lining cells provide the major driving force for tooth movement and osteoclastogenesis in response to orthodontic forces.

Background/Aims: Despite the high efficacy of direct-acting antivirals (DAAs), approximately 1–3% of hepatitis C virus (HCV) patients fail to achieve a sustained virological response. We conducted a nationwide study to investigate risk factors associated with DAA treatment failure. Machine-learning algorithms have been applied to discriminate subjects who may fail to respond to DAA therapy. Methods: We analyzed the Taiwan HCV Registry Program database to explore predictors of DAA failure in HCV patients. Fifty-five host and virological features were assessed using multivariate logistic regression, decision tree, random forest, eXtreme Gradient Boosting (XGBoost), and artificial neural network. The primary outcome was undetectable HCV RNA at 12 weeks after the end of treatment. Results: The training (n=23,955) and validation (n=10,346) datasets had similar baseline demographics, with an overall DAA failure rate of 1.6% (n=538). Multivariate logistic regression analysis revealed that liver cirrhosis, hepatocellular carcinoma, poor DAA adherence, and higher hemoglobin A1c were significantly associated with virological failure. XGBoost outperformed the other algorithms and logistic regression models, with an area under the receiver operating characteristic curve of 1.000 in the training dataset and 0.803 in the validation dataset. The top five predictors of treatment failure were HCV RNA, body mass index, α-fetoprotein, platelets, and FIB-4 index. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the XGBoost model (cutoff value=0.5) were 99.5%, 69.7%, 99.9%, 97.4%, and 99.5%, respectively, for the entire dataset. Conclusions Machine learning algorithms effectively provide risk stratification for DAA failure and additional information on the factors associated with DAA failure.
