Cross-cultural translation and validation of the Chinese version Distress Tolerance Scale for adolescents with chronic physical disease.

INTRODUCTION: Chronic physical disease (CPD) makes life filled with many negative events in adolescents, but not all adolescents experiencing negative life events proceed to develop emotional distress, only those with low emotional distress tolerance (EDT). A valid and reliable scale to measure EDT in CPD adolescents is important for caring for their emotional distress. Therefore, the purpose of this study is to translate the 15-item English version Distress Tolerance Scale (DTS) into a Chinese version and then validate the scale for measuring EDT of adolescents with CPD. METHODS: The 15-item English version DTS was translated into a Chinese version using the translation guidelines for cross-cultural research. Two cohorts of adolescents with CPD were recruited from four hospitals in southern Taiwan, with the first cohort including 124 adolescents with CPD employed to conduct exploratory factor analysis, corrected item-total correlation and reliability testing, while the second cohort, consisting of 238 adolescents with CPD, was utilized to examine confirmatory factor analysis and concurrent validity. RESULTS: The two-factor nine-item Chinese version DTS for Adolescents with CPD (C-DTS-A) was developed. Lower scores of the C-DTS-A were significantly associated with higher diabetes distress, poorer self-management, and worse glycaemic control; their correlation coefficients sequentially were -.40, .17 and -.23. Cronbach's α and the test-retest reliability of the two-factor C-DTS-A ranged from .81 to .87 and from .79 to .89, respectively. CONCLUSION: The two-factor nine-item C-DTS-A with good cross-cultural translation quality was a reliable and valid scale to assess EDT for adolescents with CPD.

Predictive models of recurrent implantation failure in patients receiving ART treatment based on clinical features and routine laboratory data.

STUDY QUESTION: The objective was to construct a model for predicting the probability of recurrent implantation failure (RIF) after assisted reproductive technology (ART) treatment based on the clinical characteristics and routine laboratory test data of infertile patients. A model was developed to predict RIF. The model showed high calibration in external validation, helped to identify risk factors for RIF, and improved the efficacy of ART therapy. WHAT IS KNOWN ALREADY: Research on the influencing factors of RIF has focused mainly on embryonic factors, endometrial receptivity, and immune factors. However, there are many kinds of examinations regarding these aspects, and comprehensive screening is difficult because of the limited time and economic conditions. Therefore, we should try our best to analyse the results of routine infertility screenings to make general predictions regarding the occurrence of RIF. STUDY DESIGN, SIZE, DURATION: A retrospective study was conducted with 5212 patients at the Reproductive Center of the First Affiliated Hospital of USTC from January 2018 to June 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS: This study included 462 patients in the RIF group and 4750 patients in the control group. The patients' basic characteristics, clinical treatment data, and laboratory test indices were compared. Logistic regression was used to analyse RIF-related risk factors, and the prediction model was evaluated by receiver operating characteristic (ROC) curves and the corresponding areas under the curve (AUCs). Further analysis of the influencing factors of live births in the first cycle of subsequent assisted reproduction treatment in RIF patients was performed, including the live birth subgroup (n = 116) and the no live birth subgroup (n = 200). MAIN RESULTS AND THE ROLE OF CHANCE: (1) An increased duration of infertility (1.978; 95% CI, 1.264-3.097), uterine cavity abnormalities (2.267; 95% CI, 1.185-4.336), low AMH levels (0.504; 95% CI, 0.275-0.922), insulin resistance (3.548; 95% CI, 1.931-6.519), antinuclear antibody (ANA)-positive status (3.249; 95% CI, 1.20-8.797) and anti-ß2-glycoprotein I antibody (A-ß2-GPI Ab)-positive status (5.515; 95% CI, 1.481-20.536) were associated with an increased risk of RIF. The area under the curve of the logistic regression model was 0.900 (95% CI, 0.870-0.929) for the training cohort and 0.895 (95% CI, 0.865-0.925) for the testing cohort. (2) Advanced age (1.069; 95% CI, 1.015-1.126) was a risk factor associated with no live births after the first cycle of subsequent assisted reproduction treatment in patients with RIF. Blastocyst transfer (0.365; 95% CI = 0.181-0.736) increased the probability of live birth in subsequent cycles in patients with RIF. The area under the curve of the logistic regression model was 0.673 (95% CI, 0.597-0.748). LIMITATIONS, REASONS FOR CAUTION: This was a single-centre regression study, for which the results need to be evaluated and verified by prospective large-scale randomized controlled studies. The small sample size for the analysis of factors influencing pregnancy outcomes in subsequent assisted reproduction cycles for RIF patients resulted in the inclusion of fewer covariates, and future studies with larger samples and the inclusion of more factors are needed for assessment and validation. WIDER IMPLICATIONS OF THE FINDINGS: Prediction of embryo implantation prior to transfer will facilitate the clinical management of patients and disease prediction and further improve ART treatment outcomes.

Topical Antibiotic Prophylaxis for Preventing Surgical Site Infections of Clean Wounds: A Systematic Review and Meta-Analysis.

Background: Topical antibiotic agents are not generally indicated for preventing of surgical site infections (SSIs) in clean incisions, and the drug concentrations that should be delivered to local incision sites remain uncertain. The aim of this study was to critically assess the efficacy of topical antibiotic agents in comparison with non-antibiotic agents for preventing SSIs in clean incisions by performing a systematic review and meta-analysis. Methods: We conducted a search of literature in PubMed, Embase, and Cochrane Databases and included randomized controlled trials (RCTs) on topical antibiotic use for patients with clean post-surgical incisions. The primary outcome was the incidence of SSI, presented as the event rate. Eleven RCTs were included. Results: Using random-effects modeling, the pooled risk ratio (RR) of developing a post-surgical incisions infection was 0.83 (95% confidence interval [CI], 0.61-1.16; I2, 0%). In subgroup analyses, no reductions in SSI were observed when topical antibiotic agents were used to treat incisions due to spinal (RR, 0.75; 95% CI, 0.40-1.38; I2, 0%), orthopedic (RR, 0.69; 95% CI, 0.37-1.29; I2, 0%), dermatologic (RR, 0.77; 95% CI, 0.39-1.55; I2, 65%), or cardiothoracic surgeries (RR, 1.31; 95% CI, 0.83-2.06; I2: 0%). The incidence of SSI across different operative phases did not differ for the application of topical antibiotic agents compared with non-antibiotic agents (RR, 0.80; 95% CI, 0.56-1.14; I2, 0%). Conclusions: The results of this meta-analysis show that topical antibiotic agents provide no clinical benefit for preventing SSI in clean incisions.

Age as a modifier of the effects of sarcopenia on survival among colon cancer patients after surgery.

BACKGROUND: Studies have been conducted to evaluate whether sarcopenia is a predictor for survival in patients with colon cancer postsurgery, but findings have been inconsistent, and effects of age were seldom evaluated. METHODS: We recruited 133 patients with resectable colon cancer who underwent surgery between January 2014 and December 2017 at a teaching hospital to evaluate the effects of sarcopenia on survival, after adjusting for age and other potential predictors, including visceral adiposity (VA). RESULTS: Preoperative sarcopenia was associated with worse overall survival (OS: 62.3% vs. 83.8%, p = 0.04) and longer hospital stay (20.6 vs. 14.9 days, p < 0.01) while VA was not. Cox proportional hazards regressions showed that sarcopenia was associated with an adjusted hazard ratio (HR) of 2.91 (95% confidence interval [CI]: 1.08-7.86) after adjustment for other independent risk factors, but was not associated with disease free survival. In stratified analyses, we found that sarcopenia was an independent factor for worse OS (adjusted HR = 1.94; 95% CI: 1.11-3.38) among patients >70 years, but not among patients ≤70 years (HR = 0.48; 95% CI: 0.55-4.55). CONCLUSIONS: Age appeared to be a modifier of the effects of sarcopenia on OS among colon cancer patients postsurgery.

Safety of early cumulus cell removal combined with early rescue ICSI in the prevention of fertilization failure.

RESEARCH QUESTION: What are the clinical outcomes and safety implications of early cumulus cell removal after short-term insemination combined with early rescue intracytoplasmic sperm injection (ICSI) in preventing fertilization failure? DESIGN: In this retrospective study, a total of 14,360 cycles were divided into four groups based on insemination method and fertilization ability: conventional IVF group (n = 5519); early cumulus cell removal group (n = 4107); conventional ICSI group (n = 4215); and early rescue ICSI group (where failed or low fertilization was predicted, n = 519). Fertilization outcomes, pregnancy outcomes, neonatal outcomes and birth defects were analysed by comparing the early cumulus cell removal group with the conventional IVF group, and the early rescue ICSI group with the conventional ICSI group. RESULTS: There were no significant differences in the outcomes of fertilization, pregnancy, neonates or birth defects between the conventional IVF group and the early cumulus cell removal group (P > 0.05). When compared with the conventional ICSI group, the early rescue ICSI group had similar rates of two pronuclei (2PN) at fertilization, clinical pregnancy, miscarriage, ectopic pregnancy, live birth, sex, mean gestational age, very low birthweight, macrosomia and birth defects (P > 0.05) but a higher polyploidy rate, lower high-quality embryo rate (both P < 0.001), lower twin pregnancy rate (P < 0.01), lower rate of low birthweight, and a higher rate of normal birthweight (both P = 0.024). CONCLUSIONS: Early cumulus cell removal combined with early rescue ICSI led to good pregnancy and neonatal outcomes without an increase in birth defects. This approach could therefore be an effective and safe method for patients with fertilization failure in conventional IVF.

Quality of self-report coping measures for children and adolescents with cancer: A systematic review.

BACKGROUND: Cancer and its treatments cause significant stress in children and adolescents. This stress is associated with risks of emotional and behavioral problem development and interfering with adherence to treatment regimens. Instruments enabling the precise evaluation of the coping behaviors of pediatric patients with cancer in clinical practice are needed. AIMS: The study aimed to identify existing self-report measures of pediatric coping patterns and to evaluate their psychometric properties, to aid the selection of tools for application to pediatric patients with cancer. METHODS: This systematic review was conducted according to the PRISMA statement and registered in PROSPERO (CRD 42021279441). Nine international databases were searched from their inception to September 2021. Studies with the main goal of developing and psychometrically validating pediatric coping measures with populations aged <20 years, not specific to any disease or situation, and published in English, Mandarin, or Indonesian were included. The Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist was applied. RESULTS: Of 2527 studies initially identified, 12 met the inclusion criteria. Five scales had positive internal consistency ratings and adequate reliability (α > .7). Construct validity ratings were positive for five scales (41.6%), intermediate for three (25%), and poor for three (25%). No information was available for one (8.3%) scale. The Coping Scale for Children and Youth (CSCY) and Pediatric Cancer Coping Scale (PCCS) had the largest numbers of positive ratings. Only the PCCS was developed for pediatric patients with cancer and showed acceptable reliability and validity. LINKING EVIDENCE TO ACTION: The findings of this review highlight the need to increase the validation of existing coping measures in clinical and research settings. Some instruments seem to be specific to adolescent's cancer coping assessment and knowledge of these validity and reliability of the instruments may improve the quality of clinical interventions.

Anticancer Therapy and Mortality of Adult Patients with Hematologic Malignancy and COVID-19: A Systematic Review and Meta-Analysis.

Coronavirus disease 2019 (COVID-19) might affect cancer treatment outcomes. This systematic review and meta-analysis identified the prognostic predictors of adult patients with hematologic malignancies and COVID-19, and evaluated the effect of anticancer therapy on mortality. We performed a literature search of electronic databases and identified additional studies from the bibliographies of the articles that were retrieved. Two investigators independently extracted data according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines. We evaluated study quality using the Newcastle-Ottawa Scale and performed a meta-analyses in order to evaluate the effect of anticancer therapy on mortality among adult patients with hematologic malignancies and COVID-19. Heterogeneity was assessed with the I2 statistic. The meta-analysis included 12 studies. The overall mortality rate was 36.3%. The pooled risk difference (RD) in mortality between patients receiving and not receiving anticancer therapy was 0.14 (95% confidence interval [CI]: 0.02-0.26; I2 = 76%). The pooled RD in mortality associated with chemotherapy was 0.22 (95% CI: 0.05-0.39; I2 = 48%), and with immunosuppression was 0.20 (95% CI: 0.05-0.34; I2 = 67%). In the subgroup analyses, anticancer-therapy-associated mortality was higher in females (RD = 0.57; 95% CI: 0.29-0.85; I2 = 0%) than in males (RD = 0.28; 95% CI: 0.04-0.52; I2 = 0%). Among patients with hematologic malignancies and COVID-19, those receiving anticancer therapy had a higher mortality risk, regardless of sex. The mortality risk was higher in females than in males. These results indicate that caution should be exercised when administering anticancer therapy to patients with hematologic malignancies and COVID-19.

Hederagenin improves Alzheimer's disease through PPARα/TFEB-mediated autophagy.

BACKGROUND: Autophagic flux is coordinated by a network of master regulatory genes, which centered on transcription factor EB (TFEB). The disorders of autophagic flux are closely associated with Alzheimer's disease (AD), and thus restoring autophagic flux to degrade pathogenic proteins has become a hot therapeutic strategy. Hederagenin (HD), a triterpene compound, isolated from a variety food such as Matoa (Pometia pinnata) Fruit, Medicago sativa, Medicago polymorpha L. Previous studies have shown that HD has the neuroprotective effect. However, the effect of HD on AD and underlying mechanisms are unclear. PURPOSE: To determine the effect of HD on AD and whether it promotes autophagy to reduce AD symptoms. STUDY DESIGN: BV2 cells, C. elegans and APP/PS1 transgenic mice were used to explore the alleviative effect of HD on AD and the molecular mechanism in vivo and in vitro. METHODS: The APP/PS1 transgenic mice at 10 months were randomized into 5 groups (n = 10 in each group) and orally administrated with either vehicle (0.5% CMCNa), WY14643 (10 mg/kg/d), low-dose of HD (25 mg/kg/d), high-dose of HD (50 mg/kg/d) or MK-886 (10 mg/kg/d) + HD (50 mg/kg/d) for consecutive 2 months. The behavioral experiments including morris water maze test, object recognition test and Y maze test were performed. The effects of HD on Aß deposition and alleviates Aß pathology in transgenic C. elegans were operated using paralysis assay and fluorescence staining assay. The roles of HD in promoting PPARα/TFEB-dependent autophagy were investigated using the BV2 cells via western blot analysis, real-time quantitative PCR (RT-qPCR), molecular docking, molecular dynamic (MD) simulation, electron microscope assay and immunofluorescence. RESULTS: In this study, we found that HD upregulated mRNA and protein level of TFEB and increased the distribution of TFEB in the nucleus, and the expressions of its target genes. HD also promoted the expressions of LC3BII/LC3BI, LAMP2, etc., and promoted autophagy and the degradation of Aß. HD reduced Aß deposition in the head area of C. elegans and Aß-induced paralysis. HD improved cognitive impairment and pathological changes in APP/PS1 mice by promoting autophagy and activating TFEB. And our results also showed that HD could strongly target PPARα. More importantly, these effects were reversed by treatment of MK-886, a selective PPARα antagonist. CONCLUSION: Our present findings demonstrated that HD attenuated the pathology of AD through inducing autophagy and the underlying mechanism associated with PPARα/TFEB pathway.

Exploring the Taiwanese Anticipatory Experience of Grief Among Primary Caregivers in Palliative Home Care.

Aims and Objectives: The goal of the present study was to explore anticipatory grief experiences among primary caregivers in home-based palliative care. We placed a special emphasis on coping methods adopted by individuals from Eastern cultures when facing death. Background: Most patients prefer spending their last days at home, which often exerts considerable physical and mental stress on their primary caregivers. Design: This study adopted a qualitative exploratory research design and used open-ended in-depth interviews to explore anticipatory grief experiences among primary caregivers of patients receiving palliative home care. Methods: In the study of the factors that Anticipatory Experience of Grief among Primary Caregivers in Palliative Home Care, we used the phenomenological approach and methods to glean answers. Posters and snowball sampling were used to individually recruit participants. In total, 16 primary hospice home caregivers participated. We used semi-structured interviews to collect data. The interviews were audio-recorded in a quiet location. Each interview was divided into two to three sessions, and each session lasted 60-90 minutes. For data analysis, field notes and audio recordings are transcribed into protocols. A thematic analysis method was used to analyze the context of the interviews. Sampling and analysis processes were repeated until theoretical saturation was achieved. Results: Four major themes emerged from the categorized interview data: meaning and manifestation as to the essence of life, the art of coping with death, realization and the gift of death, and adapting, coping with, and controlling emotions. Additionally, we observed, as with many Eastern cultures, a lunar calendar death in July and crying at the death of a relative is considered taboo. Conclusions: The coping methods adopted by individuals in Eastern cultures when facing death were summarized accordingly. These findings could serve as a reference to better understand the coping mechanisms these individuals use to address anticipatory grief when facing a family member's impending death. Relevance to Clinical Practice: Potential relevance for the present findings include acceptance of Eastern cultural grief customs, early hospice and palliative care interventions for helping individuals adjust to their grief, case management and resource consolidation, providing 24-hour telephone consultation services, regular assessment visits, and developing localized teaching materials for life-and-death education.

Association between semen collection time and semen parameters: an observational study.

The process of semen collection plays a key role in the quality of semen specimens. However, the association between semen collection time and semen quality is still unclear. In this study, ejaculates by masturbation from 746 subfertile men or healthy men who underwent semen analysis were examined. The median (interquartile range) semen collection time for all participants was 7.0 (5.0-11.0) min, and the median time taken for semen collection was lower in healthy men than that in subfertile men (6.0 min vs 7.0 min). An increase in the time required to produce semen samples was associated with poorer semen quality. Among those undergoing assisted reproductive technology (ART), the miscarriage rate was positively correlated with the semen collection time. After adjusting for confounders, the highest quartile (Q4) of collection time was negatively associated with semen volume and sperm concentration. A longer time to produce semen samples (Q3 and Q4) was negatively correlated with progressive and total sperm motility. In addition, there was a significant negative linear association between the semen collection time and the sperm morphology. Higher risks of asthenozoospermia (adjusted odds ratio [OR] = 2.06, 95% confidence interval [CI]: 1.31-3.25, P = 0.002) and teratozoospermia (adjusted OR = 1.98, 95% CI: 1.10-3.55, P = 0.02) were observed in Q3 than those in Q1. Our results indicate that a higher risk of abnormal semen parameter values was associated with an increase in time for semen collection, which may be related to male fertility through its association with semen quality.

[Mechanism of Atractylodes macrocephala against Alzheimer's disease via regulating lysophagy based on LKB1-AMPK-TFEB pathway].

Myloid beta(Aß) is produced by cleavage of amyloid precursor protein(APP), which is a main reason for Alzheimer's disease(AD) occurrence and development. This study preliminarily investigated the mechanism of Atractylodes macrocephala(AM) against AD based on LKB1-AMPK-TFEB pathway. The effect of AM on memory ability of AD transgenic Caenorhabditis elegans CL2241 was detected, and then the APP plasmid was transiently transferred to mouse neuroblastoma(N2 a) cells in vitro. The mice were divided into the blank control group, APP group(model group), positive control group(100 µmol·L~(-1) rapamycin), and AM low-, medium-and high-dose groups(100, 200 and 300 µg·mL~(-1)). The content of Aß_(1-42) in cell medium, the protein level of APP, the fluorescence intensity of APP, the transcriptional activity of transcription factor EB(TFEB), the activity of lysosomes in autophagy, and autophagy flux were determined by enzyme-linked immunosorbent assay(ELISA), Western blot, fluorescence microscope, luciferase reporter gene assay, RLuc-LC3 wt/RLuc-LC3 G120 A, and mRFP-GFP-LC3, respectively. The protein expression of TFEB, LC3Ⅱ, LC3Ⅰ, LAMP2, Beclin1, LKB1, p-AMPK and p-ACC was detected by Western blot. Immunofluorescence and reverse transcription-polymerase chain reaction(RT-PCR) were used to detect the fluorescence intensity of TFEB and the mRNA expression of TFEB and downstream target genes, respectively. The results showed that AM reduced the chemotactic index of transgenic C. elegans CL2241, and decreased the content of Aß in the supernatant of cell culture medium at different concentrations. In addition, AM lowered the protein level of APP and the fluorescence intensity of APP in a dose-dependent manner. Transcriptional activity of TFEB and fluorescence intensity of mRFP-GFP-LC3 plasmid were enhanced after AM treatment, and the value of RLuc-LC3 wt/RLuc-LC3 G120 A was reduced. AM promoted the protein levels of TFEB, LAMP2 and Beclin1 at different concentrations, and increased the protein expression ratio of LC3Ⅱ/LC3Ⅰ in a dose-dependent manner. Immunofluorescence results revealed that AM improved the fluorescence intensity and nuclear expression of TFEB, and RT-PCR results indicated that AM of various concentrations elevated the mRNA expression of TFEB in APP transfected N2 a cells and promoted the transcription level of LAMP2 in a dose-dependent manner, and high-concentration AM also increased the mRNA levels of LC3 and P62. The protein levels of LKB1, p-AMPK and p-ACC were elevated by AM of different concentrations. In summary, AM regulating lysophagy and degrading APP are related to the activation of LKB1-AMPK-TFEB pathway.

[Shared Decision-Making in Care for Pediatric Patients With Cancer: Practices and Challenges].

Shared decision-making (SDM) is a process of patient-centered clinical reasoning used to promote mutual respect and communication between doctors and patients. The medical team provides empirical data on different treatments. After communicating with patients and families, they discuss and exchange information with each other to achieve the best results from the available treatment options. Therefore, SDM is a current clinical care trend that may improve patients' disease knowledge and decrease treatment-related conflicts. However, SDM has not been extended to children and adolescents. This literature review article introduces the philosophy of SDM and practices and challenges of implementing SDM in children with cancer. We believe this article will enrich the clinical practice of SDM in children with cancer and improve related quality of care and family-centered care.

The journey of embracing life: Mothers' perspectives of living with their children with retinoblastoma.

PURPOSE: This study aimed to explore the experience and views of mothers with children who have been diagnosed with retinoblastoma. DESIGN AND METHODS: A descriptive qualitative study was conducted in the period of 2019-2021. Interviews were conducted with 21 mothers of children diagnosed with retinoblastoma in Indonesia. Data were collected by semi-structured interviews and examined by content analysis. RESULTS: Mothers evolved from a sense of unacceptability to accepting challenges and gaining inner strength. Three themes were identified: 1) physical and psychological suffering, 2) awareness of changes and demands, and 3) keep moving forward. Mothers developed positive adaptive mechanisms for coping with the problems associated with having a child with retinoblastoma. Psychological adjustment and religious beliefs were key elements in their journeys toward embracing life in the moment. CONCLUSION: Findings illuminated psychological adaptation and coping strategies of mothers with seriously ill children and highlighted how difficulties and cultural norms shaped the adaptative process. Religion and health beliefs played varied and important roles in helping mothers to manage their stress and enhance their coping strategies. PRACTICE IMPLICATIONS: Our findings revealed that it is important to routinely assess social support, traditional health beliefs, and spirituality on mothers, facilitate mentoring to help mothers find their inner strengths, and develop intervention programs designed to promote psychological adjustment without delaying treatment.

Psychometric Evaluation of the Capstone Core Competency Scale on Nursing Students in Taiwan.

BACKGROUND: Previous studies have evaluated the competency of newly graduated nurses and nurses. However, most of the instruments used include a large number of items that make completing them a time-consuming process. A brief instrument may be more acceptable and feasible for use in these evaluations. PURPOSE: This study was designed to develop the brief capstone core competency (CCC or 3C) scale and validate its effectiveness in evaluating the academic and practical performance of nursing students enrolled in a bachelor's degree program. METHODS: A cross-sectional study was conducted. The 3C scale was developed in two phases. In Phase I, the items were summed from literature reviews, an expert panel, known-groups validity, test-retest reliability, internal consistency reliability, and exploratory factor analysis. In Phase II, the efficacy of the instrument was confirmed using confirmative factor analysis. Five hundred ninety-six participants participated in the first phase, and 520 participants participated in the second phase. The study period was 2016-2017. RESULTS: The 3C scale includes 24 items distinguished into a three-component structure that accounts for 67.85% of the total variance. The three components include nursing intelligence, nursing humanity, and nursing career. The 3C scale was found to have high levels of internal consistency reliability (.97) and test-retest stability reliability ( r = .97). A significant statistical difference in the performance level was examined between senior and junior nursing students. The hypothesized three-factor model fit index showed χ 2 / df = 1338.25/249, p < .001, goodness-of-fit index = .82, comparative fit index = .90, root mean square error of approximation = .09, and standardized root mean square residual = .06. The participants were found to have excellent nursing humanity competency. CONCLUSIONS: The developed 3C scale exhibited satisfactory reliability and validity for use with nursing students. The 3C scale may be used to evaluate the performance of nursing students during their learning process, and the results may be used to evaluate changes in educational outcomes.

A recurrent homozygous missense mutation in CCDC103 causes asthenoteratozoospermia due to disorganized dynein arms.

Asthenoteratozoospermia is one of the most severe types of qualitative sperm defects. Most cases are due to mutations in genes encoding the components of sperm flagella, which have an ultrastructure similar to that of motile cilia. Coiled-coil domain containing 103 (CCDC103) is an outer dynein arm assembly factor, and pathogenic variants of CCDC103 cause primary ciliary dyskinesia (PCD). However, whether CCDC103 pathogenic variants cause severe asthenoteratozoospermia has yet to be determined. Whole-exome sequencing (WES) was performed for two individuals with nonsyndromic asthenoteratozoospermia in a consanguineous family. A homozygous CCDC103 variant segregating recessively with an infertility phenotype was identified (ENST00000035776.2, c.461A>C, p.His154Pro). CCDC103 p.His154Pro was previously reported as a high prevalence mutation causing PCD, though the reproductive phenotype of these PCD individuals is unknown. Transmission electron microscopy (TEM) of affected individuals' spermatozoa showed that the mid-piece was severely damaged with disorganized dynein arms, similar to the abnormal ultrastructure of respiratory ciliary of PCD individuals with the same mutation. Thus, our findings expand the phenotype spectrum of CCDC103 p.His154Pro as a novel pathogenic gene for nonsyndromic asthenospermia.

Developing the Chinese version problem areas in diabetes-teen for measuring diabetes distress in adolescents with type 1 diabetes.

PURPOSE: To translate the 26-item English version Problem Areas in Diabetes-Teen (PAID-T) into a Chinese version and then to examine its psychometrical properties for measuring diabetes distress in adolescents with type 1 diabetes (T1D). DESIGN AND METHODS: The 26-item English version PAID-T was translated into a Chinese version guided by the translation model for cross-cultural research. A cross-sectional design was used and 203 adolescents with T1D were recruited from four hospitals in Taiwan. Content validity, exploratory factor analysis, and item analysis were used to ensure the item quality and build the factor structure of the Chinese version PAID-T. Confirmatory factor analysis, concurrent validity, and reliability testing were also used to examine its psychometric properties. RESULTS: The three second-order factors of the 18-item Chinese version PAID-T were developed. The correlation coefficients of the three-factor Chinese version PAID-T with self-management and glycosylated hemoglobin levels were all significant and ranged from -0.32 to -0.45 and 0.18 to 0.33 respectively. Cronbach's α and the test-retest reliability of the three-factor Chinese version PAID-T ranged from 0.85 to 0.93 and from 0.89 to 0.94 respectively. CONCLUSIONS: The Chinese version PAID-T with good translation quality was a reliable and valid scale to screen and assess diabetes distress for adolescents with T1D. PRACTICE IMPLICATIONS: Nurses could use the Chinese version PAID-T to track diabetes distress and tailor interventions for adolescents with T1D; also, the Chinese version PAID-T could facilitate the conducting of research on diabetes distress for adolescents with T1D.

Decisional conflicts, anxiety, and perceptions of shared decision-making in cancer treatment trajectory among adolescents with cancer: A longitudinal study.

PURPOSE: To examine the trajectory of decisional conflict and anxiety experienced by adolescents after the cancer diagnosis, and explore their perceptions on participation in shared decision-making (SDM). DESIGN: This longitudinal study used incorporated data from questionnaires and interviews. METHODS: Participants recruited from an academic hospital in southern Taiwan ranged in age from 13 to 20 years with a cancer diagnosis within 1 month and received cancer treatment. Each participant completed questionnaires on decisional conflict and anxiety at diagnosis, 1, 3, and 6 months later. Individual interviews were to gain an in-depth understanding of SDM. FINDINGS: Total scores on decisional conflict changed significantly over time (F = 2.98, p = 0.039); the scores at 1 month were higher than 3 months (t = 2.18, p = 0.04) and 6 months (t = 2.97, p = 0.008). Participants perceived significantly different levels of values clarify (F = 9.49, p < 0.01) and support (F = 8.46, p < 0.01) over time. Only 27.3% of participants were anxiety-free. No significant differences were found in anxiety over time. The perception of SDM was a situational involvement. CONCLUSIONS: Decisional conflict changed over time. Participants experienced greater decisional conflict at 4-8 weeks after diagnosis and their anxiety did not decrease over time. The different levels of participation in SDM during their treatment trajectory were found. CLINICAL RELEVANCE: Participants experienced the highest decisional conflict during diagnosis, and highlighted how their roles in healthcare discussions varied from direct participation to indirect involvement. Further research is needed to develop an SDM model which accommodates different levels of needs and implements timely support.

Association between sarcopenia and survival in patients with gynecologic cancer: A systematic review and meta-analysis.

Background: Despite prior attempts to evaluate the effects of sarcopenia on survival among patients with gynecologic cancer, the results of these studies have not been consistent. The present study evaluated the association between sarcopenia and survival among patients with gynecologic cancer by aggregating multiple studies. Methods: We performed a literature search using computerized databases and identified additional studies included in the bibliographies of retrieved articles. The quality of each study was evaluated using the Newcastle-Ottawa Scale, and meta-analyses were performed to evaluate overall survival (OS) and progression-free survival (PFS). We constructed a forest plot for each outcome and assessed publication bias using Begg's test. Heterogeneity was assessed using I2 statistics. Results: From the 5,933 initially identified articles, 16 studies describing 2,031 participants with a mean age of 60.34 years were included in the meta-analysis. We found that compared with patients with gynecologic cancer but without sarcopenia, patients with sarcopenia had worse OS, with a pooled hazard ratio (HR) of 2.61 (95% confidence interval [CI]:1.52-4.46), and worse PFS (HR: 1.37, 95% CI: 1.09-1.73). The quality of studies was generally good, and no publication bias was detected among studies for either OS or PFS. Although 4 of 12 studies were of fair quality, we conducted a sensitivity analysis excluding studies or fair quality and obtained similar results. Conclusions: These meta-analysis results suggest that sarcopenia is associated with worse OS and PFS among patients with gynecologic cancer. The use of different case definitions appeared to be a major source of heterogeneity among the studies. Further studies remain necessary to confirm our findings, especially those examining OS and PFS, because publication bias was identified.

Two new sesquiterpenes from the rhizomes of Atractylodes macrocephala and their biological activities.

Two new sesquiterpenes, named selina-4(14),7,11-trien-9-ol (1) and selina-4(14),11-dien-7-ol (2), along with two known compounds were isolated from rhizomes of Atractylodes macrocephala Koidz. All structures were assigned on the basis of detailed spectroscopic analyses. The absolute configuration of 1 was established by TDDFT-ECD calculations. Compound 1 was found to moderately inhibit LSD1 activity with IC50 value of 34.0 µM. Compounds 1 and 4 exhibited a regulate effect on Keap1-Nrf2-ARE pathway.[Formula: see text].
