The Numerical Simulations and Experimental Study of an 8-Inch SiC Single Crystal with Reduced BPD Density.

The basal plane dislocation (BPD) density is one of the most important defects affecting the application of SiC wafers. In this study, numerical simulations and corresponding experiments were conducted to investigate the influence of cooling processes, seed-bonding methods, and graphite crucible materials on the BPD density in an 8-inch N-type 4H-SiC single crystal grown by the physical vapor transport (PVT) method. The results showed that the BPD density could be effectively reduced by increasing the cooling rate, optimizing the seed-bonding method, and adopting a graphite crucible with a similar coefficient of thermal expansion as the SiC single crystal. The BPD density in the experiments showed that a high cooling rate reduced the BPD density from 4689 cm-2 to 2925 cm-2; optimization of the seed-bonding method decreased the BPD density to 1560 cm-2. The BPD density was further reduced to 704 cm-2 through the adoption of a graphite crucible with a smaller thermal expansion coefficient.

Effects of three kinds of Chinese herbs on growth performance, oocysts output and gut microbiota in growing lambs with coccidiosis.

Coccidiosis is a protozoan intestinal disease that reduces the production of the sheep industry and causes large economic losses for sheep. Although chemically synthesised drugs are routinely employed to treat coccidiosis in sheep, the anticoccidial drug resistance and drug residues in edible meat have prompted an urgent search for alternatives. Herein, the anticoccidial properties of diclazuril, a conventional anticoccidial drug, and Allium sativum, Houttuynia cordata and Portulaca oleracea were assessed. Forty 45-day-old lambs naturally infected with Eimeria spp. were selected and randomly divided into five groups. The results showed that the sheep treated for coccidiosis had considerably decreased average daily gain (ADG) during both administration and withdrawal of the drug compared to the control group. Furthermore, at days 14, 21, 28 and 35, respectively, the three herbs and diclazuril had similar anticoccidial effects, with lower oocysts per gram (OPG) than the control group. On day 78, OPG in the three herbal groups was significantly lower than in the diclazuril group. In addition, the abundance and composition of the gut microbiota were changed in sheep treated with the three herbs and diclazuril compared to the untreated sheep. Moreover, some intestinal microorganisms have a correlation with OPG and ADG when using Spearman correlation analysis. In summary, our results suggest that all three herbs produce anticoccidial effects similar to diclazuril and modulate the balance of gut microbiota in growing lambs.

Effects of Radix dichroae extract supplementation on growth performance, oocysts output and gut microbiota in growing lambs with coccidiosis.

Coccidiosis is an intestinal protozoan disease of sheep, that causes substantial economic losses in the industry due to its intestinal protozoan origins. Many anti-protozoan drugs including ionophores, triazines, and sulfonamides have been widely used to treat sheep coccidiosis. Still, anticoccidial resistance and drug residues in edible tissues have prompted an urgent search for alternatives. In this study, the anti-coccidial effectiveness of the Radix dichroae extract was compared to that of the conventional anti-coccidial drug diclazuril. Here, eighteen 45-day-old lambs naturally-infected with Eimeria spp. were randomly allocated in three groups: control group, Radix dichroae extract group and diclazuril group. The results showed that the body weight gain (BWG) during the treatment and withdrawal periods was considerably improved in the coccidiosis-infected sheep treated with Radix dichroae extract and diclazuril compared to the control group, respectively. Additionally, the Radix dichroae extract and diclazuril had fewer oocysts per gram (OPG) than the control group, showing similar anti-coccidial effects on days 14, 21, 28, 35 and 78, respectively. Furthermore, Radix dichroae extract and diclazuril treatment altered the structure and composition of gut microbiota, promoting the relative abundance of Actinobacteriota, Firmicutes, Alistipes, and Bifidobacterium, while decreasing the abundance of Bacteroidota, Marinilaceae, Helicobacteraceae, and Prevotella. Moreover, Spearman's correlation analysis further revealed a correlation between the OPG and BWG and gut microorganisms. Collectively, the results indicated that Radix dichroae extract had similar anti-coccidial effects as diclazuril, and could regulate gut microbiota balance in growing lambs.

Mg ion implantation and post-annealing effect on the photoelectrical performance of a ß-Ga2O3 photodetector.

The effects of magnesium ion implantation and post-annealing on the photoelectric performance of a ß-G a 2 O 3-based vertical structural Schottky photodetector (PD) were thoroughly investigated. After implantation and post-annealing, the Schottky barrier height and bandgap of the G a 2 O 3 surface can be slightly increased, while the dark current is significantly reduced, and the light-to-dark current ratio is immensely improved. The PD exhibited a photo-to-dark current ratio of 1733, responsivity of 5.04 mA/W, and specific detectivity of 3.979×1011 Jones under -2.6V bias, and the rise and decay times are 0.157 were 0.048 s, respectively. The large left shift of the open-circuit voltage is feasibly explained by applying the thermionic-emission diffusion theory.

A bad time to die? Exploring bereaved families/wha-nau experiences of end-of-life care under COVID-19 restrictions: a qualitative interview study.

Background: There have been international concerns raised that, during the COVID-19 pandemic, there was an absence of good palliative care resulting in poor end-of-life care experiences. To date, there have been few studies considering the pandemic's impact on people dying from non-COVID-19 causes and their families and friends. In particular, there has been very less empirical research in relation to end-of-life care for Indigenous, migrant and minoritised ethnic communities. Objectives: To explore bereaved next-of-kin's views and experiences of end-of-life care under COVID-19 pandemic regulations. Design: This qualitative study involved in-depth one-off interviews with 30 ethnically diverse next-of-kin who had a family member die in the first year of the pandemic in Aotearoa, New Zealand. Methods: Interviews were conducted by ethnically matched interviewers/interviewees. A reflexive thematic analysis was used to explore and conceptualise their accounts. Results: A key finding was that dying alone and contracting COVID-19 were seen as equally significant risks by bereaved families. Through this analysis, we identified five key themes: (1) compromised connection; (2) uncertain communication; (3) cultural safety; (4) supported grieving and (5) silver linings. Conclusion: This article emphasises the importance of enabling safe and supported access for family/whanau to be with their family/wha-nau member at end-of-life. We identify a need for wider provision of bereavement support. We recommend that policy makers increase resourcing of palliative care services to ensure that patients and their families receive high-quality end-of-life care, both during and post this pandemic. Policy makers could also promote a culturally-diverse end-of-life care work force and the embedding of culturally-safety practices across a range of institutions where people die.

PlantNLRatlas: a comprehensive dataset of full- and partial-length NLR resistance genes across 100 chromosome-level plant genomes.

Plants have evolved two layers of protection against biotic stress: PAMP-triggered immunity (PTI) and effector-triggered immunity (ETI). The primary mechanism of ETI involves nucleotide-binding leucine-rich repeat immune receptors (NLRs). Although NLR genes have been studied in several plant species, a comprehensive database of NLRs across a diverse array of species is still lacking. Here, we present a thorough analysis of NLR genes across 100 high-quality plant genomes (PlantNLRatlas). The PlantNLRatlas includes a total of 68,452 NLRs, of which 3,689 are full-length and 64,763 are partial-length NLRs. The majority of NLR groups were phyletically clustered. In addition, the domain sequences were found to be highly conserved within each NLR group. Our PlantNLRatlas dataset is complementary to RefPlantNLR, a collection of NLR genes which have been experimentally confirmed. The PlantNLRatlas should prove helpful for comparative investigations of NLRs across a range of plant groups, including understudied taxa. Finally, the PlantNLRatlas resource is intended to help the field move past a monolithic understanding of NLR structure and function.

The Effects of APP-Based Intervention for Depression Among Community-Dwelling Individuals With Spinal Cord Injury: A Randomized Controlled Trial.

OBJECTIVE: To assess the effect of a self-management intervention delivered by mobile application (APP) for depression among community-dwelling individuals with spinal cord injury (SCI). DESIGN: Randomized controlled trial. SETTINGS: General communities in China. PARTICIPANTS: Community-dwelling individuals with SCI who were diagnosed within 2 years were recruited in this study (N=98). It was a convenience sample with an average age of 41.71, 82.7% participants were men. INTERVENTIONS: Participants in the intervention group (n=49) received 5 sessions on self-management training provided by nurse-led multidisciplinary team via APP at the second, fourth, sixth, eighth, and 12th weeks, respectively, after they discharge from hospitals. Participants in the control group (n=49) received routine telephone counselling provided by follow-up nurses at the 12th week after they discharge. OUTCOME MEASURE: The outcome of this study is depression, which is not the primary outcomes in the registration of this program. Depression was measured by version 2 of Beck Depression Inventory at discharge (T0), the 12th week after discharge from hospitals (T1), and the 24th week after discharge from hospitals (T2). RESULTS: There were 98 participants (49 in the intervention group and 49 in the control group) completing the intervention and data collection. Compared with the control group, the intervention group had lower level of depression at T2 (B=-5.76; 95% CI=-9.97, -1.54; P=.007). Small to moderate effect sizes on depression favoring the intervention were demonstrated at T1 (Cohen's d=-.178) and T2 (Cohen's d=-.535). CONCLUSIONS: APP-based self-management support can be a potential intervention to reduce depression among community-dwelling individuals with SCI.

Telemedicine for Preventing and Treating Pressure Injury After Spinal Cord Injury: Systematic Review and Meta-analysis.

BACKGROUND: Pressure injury is a common complication after a spinal cord injury. Long-term multidisciplinary follow-up is difficult after such patients have been discharged. Telemedicine promises to provide convenient and effective support for the prevention and treatment of pressure injury, but previous attempts to demonstrate that have produced inconsistent results. OBJECTIVE: The aim of this study is to evaluate the effectiveness of telemedicine in preventing and treating pressure injury among community-dwelling patients with spinal cord injury, and determine which telemedicine form is more effective. METHODS: This systematic review was performed according to the PRISMA-NMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Network Meta-Analysis) standards. Ten databases were searched to identify randomized controlled trials and quasi-experimental studies related to the effectiveness of telemedicine intervention in patients with spinal cord injury. Two researchers worked independently and blindly selected studies, extracted data, and assessed the risk of bias. The results were described as relative risk (RR) and weighted mean difference and 95% CI. RESULTS: The 35 studies comprised 25 randomized controlled trials and 10 quasi-experimental studies involving 3131 patients. The results showed that telemedicine can significantly (P<.05) reduce the incidence of pressure injury (RR 0.24, 95% CI 0.14-0.41; P<.05; I2=0%), promote faster healing (RR 0.73, 95% CI 0.62-0.85; P<.05; I2=0%), and yield lower scores on the pressure ulcer scale of healing (weighted mean difference=-1.98, 95% CI -3.51 to -0.46; P<.05; I2=0%). Cumulative ranking estimates showed that combining telemedicine with conventional intervention (93.5%) was the most effective approach. CONCLUSIONS: Telemedicine is a feasible way to prevent pressure injury among patients with spinal cord injuries. It can decrease the incidence and severity of pressure injury and accelerate patients' healing without imposing economic burden. It is best used in tandem with other, more conventional interventions. Due to the limited quality and quantity of included studies, large-scale and well-designed randomized controlled trials are warranted.

qPCRtools: An R package for qPCR data processing and visualization.

In biological research, qPCR is a technique that is frequently used to measure gene expression levels. The calculation of gene amplification efficiency is a critical step in the processing of qPCR data since it helps to decide which method to employ to compute gene expression levels. Here, we introduce the R package qPCRtools, which enables users to analyze the efficiency of gene amplification. Additionally, this software can determine gene expression levels using one of three approaches: the conventional curve-based method, the 2-ΔΔCt method, and the SATQPCR method. The qPCRtools package produces a table with the statistical data of each method as well as a figure with a box or bar plot illustrating the results. The R package qPCRtools is freely available at CRAN (https://CRAN.R-project.org/package=qPCRtools) or GitHub (https://github.com/lixiang117423/qPCRtools/tree/main/CRAN/qPCRtools).

Neural, adipocyte and hepatic differentiation potential of primary and secondary hair follicle stem cells isolated from Arbas Cashmere goats.

BACKGROUND: Arbas Cashmere goats are excellent domestic breeds with high yields of wool and cashmere. Their wool and cashmere can bring huge benefits to the livestock industry. Our studies intend to more fully understand the biological characteristics of hair follicle stem cells (HFSCs) in order to further explore the mechanisms of wool and cashmere regular regeneration. And they have been increasingly considered as promising multipotent cells in regenerative medicine because of their capacity to self-renew and differentiate. However, many aspects of the specific growth characteristics and differentiation ability of HFSCs remain unknown. This study aimed to further explore the growth characteristics and pluripotency of primary hair follicle stem cells (PHFSCs) and secondary hair follicle stem cells (SHFCs). RESULTS: We obtained PHFSCs and SHFSCs from Arbas Cashmere goats using combined isolation and purification methods. The proliferation and vitality of the two types of HFSCs, as well as the growth patterns, were examined. HFSC-specific markers and genes related to pluripotency, were subsequently identified. The PHFSCs and SHFSCs of Arbas Cashmere goat have a typical cobblestone morphology. Moreover, the PHFSCs and SHFSCs express HFSC surface markers, including CD34, K14, K15, K19 and LGR5. We also identified pluripotency-associated gene expression, including SOX2, OCT4 and SOX9, in PHFSCs and SHFSCs. Finally, PHFSCs and SHFSCs displayed multipotent abilities. PHFSCs and SHFSCs can be directed to differentiate into adipocyte-like, neural-like, and hepatocyte-like cells. CONCLUSIONS: In conclusion, this study confirmed that the biological characteristics and differentiation potential of PHFSCs and SHFSCs from Arbas Cashmere goats. These findings broaden and refine our knowledge of types and characteristics of adult stem cells.

Phase stability and the interface structure of a nanoscale Si crystallite in Al-based alloys.

An atomic-scale understanding of the role of strain on the microstructural properties of nanoscale precipitates will be helpful to explore the precipitation behavior as well as the structure-property relationships in crystalline multi-phase systems. Nanoscale Si precipitates are formed in Al-based alloys prepared by selective laser melting. The phase structure and the nature of heterointerface have been characterized using advanced electron microscopy. The nanocrystalline Si mainly contains two polymorphs, diamond-cubic Si (DC-Si) and 4H hexagonal Si (4H-Si). Heteroepitaxy occurs at the DC-Si(111)/Al(100) and 4H-Si(0001)/Al(100) interfaces in terms of a coincidence-site lattice model. The nanocrystalline Si undertakes tensile strain superposed by the matrix through heterointerfaces, facilitating the formation of 4H-Si in the nanoscale crystallite, which provides a strategy for designing Si polymorphic materials by strain engineering.

Association between familism and mental health in dementia caregivers: a systematic review and meta-analysis.

BACKGROUND: Dementia caregivers suffer from mental health problems while caring for dementia patients. As a core value, familism has been linked to the mental health of dementia caregivers. This study aims to systematically review the familism of dementia caregivers and to examine the association between familism and mental health of anxiety, depression, and burden in empirical research studies. METHODS: We conducted a systematic search in various databases like Medline, PubMed, and Embase databases from inception till April 2021. Fisher's z was calculated with correlation coefficient or regression coefficient values for three familism dimensions and mental health of anxiety, depression, and burden. All statistical analyses were performed using Comprehensive Meta-Analysis (CMA) version 2.0 software. RESULTS: A total of seven studies with 1178 participants were eligible for the meta-analysis. For caregivers' anxiety, three of seven studies, with 358 participants, were examined in terms of the average corrected correlation coefficient across the studies. It was found that dementia caregivers' familism was significantly related to anxiety. The pooled z-value was 0.148 (95% CI = 0.043-0.253). In addition, caregivers' familism significantly affected depression (z = 0.080; 95% CI = 0.003-0.156), as did familial obligation (z = 0.122; 95% CI = 0.034-0.211), but perceived family support was not associated with this (z = 0.051, 95% CI = -0.038-0.140). As for caregiver burden, there was no evidence that familism was significantly associated with it (z = -0.073; 95% CI = -0.297 to 0.151), including familial obligation and perceived family support (z = -0.087 and -0.089, respectively; 95% CI = -0.278 to 0.104 and -0.335 to 0.157, respectively). CONCLUSIONS: An association between caregiver familism and anxiety/depression exists in dementia patients. More research is needed to explore the relationship between familism and burden.

Cross-cultural and psychometric property assessment of the Moorong Self-Efficacy Scale in Chinese patients with spinal cord injury.

PURPOSE: To translate the Moorong Self-Efficacy Scale (MSES) into Chinese and to examine its reliability and validity in patients with spinal cord injury (SCI). METHODS: A cross-sectional study design was employed. The MSES was translated into Chinese by forward- and back-translation and its psychometric properties were examined among 176 patients with SCI recruited from four rehabilitation centers in China using convenience sampling. RESULTS: In this study, all 176 patients were aged from 18 to 90 years old with an average of 39.51 ± 14.07. The content validity index of the scale was 0.99. Principal components analysis with varimax orthogonal rotation was used. Three factors were extracted accounting for 39.083%, 11.149%, and 8.391% of the total variance and labeled as general self-efficacy (eight items), social self-efficacy (five items), and self-management self-efficacy (three items). Confirmatory factor analysis showed acceptable fit compared with previous studies. Pearson's correlation coefficient between the total scores of the MSES and the General Self-Efficacy Scale was 0.660 (p < 0.001). Cronbach's α coefficient was 0.892 for total items and 0.862, 0.817, and 0.739 for the three factors. The interclass correlation coefficients between the pretest and retest were 0.859 (0.733-0.925) for the total score. CONCLUSIONS: The Chinese version of the MSES is reliable and valid, suggesting that it is suitable for evaluating self-efficacy of Chinese patients with SCI.Implications for rehabilitationThe satisfactory reliability and validity of the Chinese version of the Moorong Self-Efficacy Scale (MSES) confirmed its suitability as a tool to measure self-efficacy among Chinese patients with spinal cord injury (SCI).The Chinese version of the MSES could be used to reflect the important and specific aspects of self-efficacy in patients with SCI such as self-care, social interaction, and daily activities, and to help medical stuff giving more targeted intervention.

High Serum Carbohydrate Antigen (CA) 125 Level Is Associated With Poor Prognosis in Patients With Light-Chain Cardiac Amyloidosis.

Background and Aims: Patients with light-chain cardiac amyloidosis (AL-CA) are characterized by high levels of serum carbohydrate antigen 125 (CA 125). However, studies have not explored the correlation between CA 125 and AL-CA. The aim of this study was to explore the clinical implications of an increase in CA 125 in patients with AL-CA. Methods and Results: A total of 95 patients diagnosed with AL-CA at the Second Xiangya Hospital were enrolled in this study. Out of the 95 patients with AL-CA, 57 (60%) patients had elevated serum CA 125 levels. The mean age was 59.7 ± 10.0 years with 44 (77.2%) men in the high serum CA 125 group, and 61.8 ± 9.6 years with 28 (73.7%) men in the normal group. Patients with high CA 125 showed higher rates of polyserositis (79.3% vs. 60.5%, p = 0.03), higher levels of hemoglobin (117.4 ± 21.9 g/L vs. 106.08 ± 25.1 g/L, p = 0.03), serum potassium (4.11 ± 0.47 mmol/L vs. 3.97 ± 0.40 mmol/L, p = 0.049), low-density lipoprotein-cholesterol (3.0 ± 1.6 mmol/L vs. 2.3 ± 1.10 mmol/L, p = 0.01), and cardiac troponin T (96.0 pg/mL vs. 91.9 pg/mL, p = 0.005). The median overall survival times for patients with high or normal serum CA 125 were 5 and 25 months, respectively (p = 0.045). Multivariate Cox hazard analysis showed that treatment without chemotherapy (HR 1.694, 95% CI 1.121-2.562, p = 0.012) and CA 125 (HR 1.002, 95% CI 1.000-1.004, p = 0.020) was correlated with high all-cause mortality. The time-dependent receiver operating characteristic (t-ROC) curve showed that the prediction accuracy of CA 125 was not inferior to that of cardiac troponin T, N-terminal pro-B-type natriuretic peptide (NT-proBNP), and lactate dehydrogenase (LDH) based on the area under the curve. Conclusions: CA 125 is a novel prognostic predictor. High serum CA 125 values are correlated with low overall survival, and the accuracy of predicting prognosis is similar to that of traditional biomarkers in AL-CA.

Effects of App-Based Transitional Care on the Self-Efficacy and Quality of Life of Patients With Spinal Cord Injury in China: Randomized Controlled Trial.

BACKGROUND: Spinal cord injury (SCI) severely impairs the physical and mental health of patients, decreasing their self-efficacy in coping with daily life and quality of life (QOL). In China, a large gap remains between the complex long-term health needs of SCI patients and the current community care system. With the prevalence of mobile terminals, the usage of mobile health apps has the potential to fill this gap by extending qualified medical resources to the families of SCI patients. Our team developed the app Together for the transitional care of home-dwelling SCI patients in China. OBJECTIVE: This study aimed to evaluate the effects of app-based transitional care on the self-efficacy and QOL of SCI patients. METHODS: Through a three-round Delphi process, an Android app was designed. Both medical staff and patients could access the app. Medical staff used it for providing remote transitional care to SCI patients. Patients used it to view transitional care time and send messages to medical staff. Thereafter, a multicenter and assessor-blinded randomized controlled trial was conducted. Participants (n=98) who had SCI and lived at home following discharge were recruited and randomly assigned to a study group (n=49) and control group (n=49) using a randomized number list in four research centers. Patients in both groups received systematic discharge education before discharge. The study group received five follow-ups conducted by trained nurses through the app, which had four core functions, namely remote assessment, health education, interdisciplinary referral, and patient interaction, at weeks 2, 4, 6, 8, and 12 following discharge. The control group received a routine telephone follow-up conducted by nurses at week 12 following discharge. The outcome measures were the Moorong Self-Efficacy Scale (MSES) and 36-item Short-Form Health Survey (SF-36) scores. Data were collected before discharge (T0) and at weeks 12 (T1) and 24 following discharge (T2). Differences between the groups were tested by repeated measures analysis of variance and simple effect analysis. RESULTS: After the follow-up, the total MSES scores in the study group improved over time (T0=67.80, T1=71.90, and T2=76.29) and were higher than those in the control group (T2=64.49) at 24 weeks following discharge (simple effect analysis: F1=8.506, P=.004). Regarding the total SF-36 score, although it was higher in patients from the study group (T2=65.36) than those from the control group (T2=58.77) at 24 weeks following discharge, only time effects were significant (F2,95=6.671, P=.002) and neither the group effects nor the interaction effects influenced the change in QOL (group effects: F1,96=0.082, P=.78; interaction effects: F2,95=3.059, P=.052). CONCLUSIONS: This study confirmed that app-based transitional care improves the self-efficacy of SCI patients. Nevertheless, QOL improvement is not yet evident. Future investigations with larger sample sizes and longer observation periods are warranted to further verify the effects.

MicroRNA-301a-3p promotes diabetic retinopathy via regulation of six-transmembrane epithelial antigen of prostate 4.

OBJECTIVE AND DESIGN: Diabetic retinopathy (DR) is one of the most serious microvascular complications of diabetes mellitus (DM). MicroRNAs (miRNAs) have been discovered to play a crucial role in DR, but the mechanisms underlying the effects of miR-301a-3p on DR are poorly understood. This paper was designed to explore the possible role of miR-301a-3p in DR. METHODS: The diabetic rat model was established by a single intraperitoneal injection of streptozotocin (STZ). The effects of miR-301a-3p on the biological functions of HRECs were determined through a series of experiments in vitro/vivo. RESULTS: The results revealed that interference with miR-301a-3p could decrease the expressions of inflammatory factors and apoptosis in the retinal tissue of DR. Furthermore, it can alleviate the oxidative stress in DR serum, reduce VEGF expression, increase endothelial cell marker expression, and inhibit (High Glucose) HG-induced apoptosis of HRECs. Six-transmembrane epithelial antigen of prostate 4 (STEAP4) was the target of miR-301a-3p. All the effects of miR-301a-3p in DR model were reversed by STEAP4 inhibitor. CONCLUSION: miR-301a-3p promotes diabetic retinopathy via regulation of STEAP4. The findings in this study may provide a vital reference for the drug research and development in DR treatment.

Excretory dysfunction and quality of life after a spinal cord injury: A cross-sectional study.

AIMS AND OBJECTIVES: To determine the aspects of excretory dysfunction most influential in determining the quality of life of survivors of spinal cord injury. BACKGROUND: Excretory dysfunction is one of the most common and troublesome sequelae of spinal cord injury. Previous studies have shown that it can restrict social participation restriction, cause readmission and generally influence quality of life substantially. DESIGN: A cross-sectional survey of hospital inpatients following STOBE guidelines. METHODS: A convenience sample of 101 patients with traumatic or non-traumatic spinal cord injury were asked about their experiences of excretory dysfunction, and management and their self-perceived quality of life. Univariate analysis and multiple linear regression were performed to isolate the most important relationships. RESULTS: Only 2 of the 101 subjects professed to be unaffected by excretion dysfunction. Bladder-related dysfunction was the most frequently mentioned type of problem. Quality of life impairment was found to be most often associated with bladder accidents, bowel accidents and having more than one bladder complications. CONCLUSIONS: Excretory dysfunction substantially impacts quality of life after a spinal cord injury. Bladder accidents, bowel accidents and more than one bladder complication are factors independently influencing the quality of life of spinal cord injury survivors. RELEVANCE TO CLINICAL PRACTICE: To improve excretion-related QOL, patients' bladder and bowel self-management training should be strengthened seeking to prevent complications and reduce the risk of bladder and bowel accidents.

Translation and validation of the Chinese version of the Spinal Cord Independence Measure (SCIM III) Self-Report.

STUDY DESIGN: A cross-sectional psychometric study. OBJECTIVE: To translate, culturally adapt and validate the Chinese version of the Spinal Cord Independence Measure III-Self Report (SCIM-SR). SETTING: Four rehabilitation centers in Guangzhou, Chengdu, and Shiyan, China. METHODS: Translation and cultural adaptation of the Chinese version of the SCIM-SR was conducted according to Brislin guidelines. A total of 147 spinal cord injury patients self-rated their functional independence using translated instrument. The psychometric properties of content validity, criterion-related validity, internal consistency reliability, and test-retest reliability were examined. RESULTS: The content validity index of the new scale was 0.99. The intraclass correlation coefficient between the total SCIM-SR and SCIM III scores was 0.935, and the coefficients for its three subscales were 0.899, 0.760, and 0.942. Bland-Altman analysis showed that the mean difference between the total SCIM-SR and SCIM III scores was 2.35 (95% confidence interval -0.58 to 5.28), and differences for the three subscales were 0.75 (-0.51-2.01), 1.30 (-0.63-3.23), and 0.30 (-0.80-1.40). The Cronbach's α coefficients for the total scale, the self-care subscale, and the mobility subscale were 0.908, 0.913, and 0.895, respectively. The α for the respiration and sphincter management subscale was 0.581. Test-retest reliability after 2 weeks yielded a Spearman coefficient for the total scale of and subscale values all above 0.73. CONCLUSIONS: Our results indicate acceptable validity and reliability of the Chinese version of SCIM-SR. It may facilitate long-term evaluations of independence in Chinese spinal cord injury patients in the community and at home.

Comparison Between Fusion and Non-Fusion Surgery for Lumbar Spinal Stenosis: A Meta-analysis.

INTRODUCTION: A large number of studies have shown that, for severe lumbar spinal stenosis, decompression surgery can often obtain better results than non-surgical treatment. However, whether the lumbar spine is fixed after decompression is still controversial. The results of biomechanical studies indicate that there is a correlation between the range of decompression and postoperative spinal instability. METHODS: The multiple databases like Pubmed, Embase, Cochrane databases and China National Knowledge database were used to search for the relevant studies, and full-text articles involved in the evaluation of fusion and nonfusion surgery for lumbar spinal stenosis. Review Manager 5.2 was adopted to estimate the effects of the results among selected articles. Forest plots, sensitivity analysis and bias analysis for the articles included were also conducted. RESULTS: A total of nine relevant studies were eventually satisfied the included criteria. There were significant differences in length of stay [mean difference (MD) = 3.04, 95% CI (2.00, 4.08), P < 0.000]1), but there were no differences in Oswestry Disability Index (ODI score) [MD = - 1.14, 95% CI (- 2.92, 0.63), P = 0.21; I2 = 87%] and complications [RR = 1 with 95% CI (0.69, 1.46), P value of overall effect was 0.98]. The study was robust and limited publication bias was observed in this study. CONCLUSION: Our research supported that fusion and nonfusion surgeries had no differences in clinical effects and complications for lumbar spinal stenosis, while fusion surgery involved a longer length of stay than nonfusion surgery.

A team approach to applying the International Classification of Functioning, Disability and Health Rehabilitation set in clinical evaluation.

OBJECTIVE: To develop a team approach to applying the International Classification of Functioning, Disability and Health Rehabilitation Set (ICF-RS) in clinical evaluation. DESIGN: A Delphi study. SUBJECTS: Experts from rehabilitation institutions in China including physicians, nurses, physiotherapists and occupational therapists. METHODS: A 2-round Delphi survey and expert panel discussion were used to generate the team approach. Firstly, the candidate types of professionals for team rating were chosen through expert panel discussion. A carefully selected group of participants was then asked to score the suitability of physicians, nurses, or other candidate therapists for each category's rat-ing, applying the International Classification of Functioning, Disability and Health Rehabilitation Set in clinical evaluation. After initial assignment of cate-gory to types of professionals, a second round Delphi survey was conducted to quantify the professionals' agreement with the category assignments and generate a final team evaluation approach. RESULTS: Thirty of the category assignments achiev-ed consensus. The final team evaluation approach assigned 6 categories to physicians to evaluate, 7 categories to nurses, 9 categories to physiotherapists, and 8 to occupational therapists. CONCLUSION: Such a team evaluation approach could facilitate implementation of the ICF-RS in clinical settings and provide a more convenient assessment tool for professionals.
