RESUMO
OBJECTIVE: To characterize the traumatic brain injury profile and its associated risk factors in homeless individuals in Santa Clara County, CA. DESIGN: Observational cohort study SETTING: : Two homeless shelter health clinics in Santa Clara County, CA PARTICIPANTS: Currently or recently homeless individuals seeking health care at two homeless shelter health clinics between August 2013 and May 2014. INTERVENTIONS: Not applicable MAIN OUTCOME MEASURES: Demographics, traumatic brain injury incidence and characteristics RESULTS: Findings indicate that TBI history in the homeless population is higher (79.7%) than the general population (12%). Almost half of the population (49.2%) reported that their TBI occurred before the age of 18. 68.2% of participants reported sustaining a TBI with loss of consciousness. TBI due to violence (60%) was lower in this cohort compared to other homeless cohorts but was the main cause of injury regardless of age. Alcoholism was a risk factor for having more TBIs. No differences in TBI profile were found between genders. CONCLUSION: Our findings underscore the need for more research on the lifetime risk factors associated with TBI to prevent and reduce the number of brain injuries in homeless populations.
RESUMO
OBJECTIVE: To examine the unique contribution of alexithymia at 1 year after traumatic brain injury (TBI) to the prospective prediction of emotional and social health outcomes at 2 years after injury. DESIGN: Multicenter, longitudinal cohort study. SETTING: Data were collected during year 1 and year 2 postinjury follow-up interviews across 4 TBI Model System centers. PARTICIPANTS: Persons with TBI (N=175; 134 men and 41 women) who had English fluency and were capable of providing self-reported data. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Primary independent variable was the Toronto Alexithymia Scale-20. Outcome measures included the Interpersonal Reactivity Index, National Institute of Health Toolbox Emotion Battery Anger, Difficulty with Emotion Regulation Scale, Connor-Davidson Resilience Scale, Posttraumatic Stress Disorder Checklist - Civilian, Satisfaction with Life Scale, General Anxiety Disorder-7, Patient Health Questionnaire 9, suicidal ideation, and problematic substance use. RESULTS: Simple adjusted models demonstrated that after controlling for the specific outcome at year 1, Toronto Alexithymia Scale-20 scores significantly predicted year 2 scores for perspective-taking, physical aggression, emotional dysregulation, resilience, anxiety, depression, and suicidal ideation. All of these predictive findings except for physical aggression were maintained in the fully adjusted models that also controlled for age, sex, education level, number of prior TBIs, and motor and cognitive functioning. CONCLUSIONS: Compared with those with lower alexithymia scores, persons with TBI who had higher alexithymia scores at 1 year after injury reported poorer emotional health at 2 years after TBI, even after controlling for year 1 outcome scores, sociodemographic characteristics, and injury-related factors. These results support the need to assess for elevated alexithymia and to provide interventions targeting alexithymia early in the TBI recovery process.

BACKGROUND: Timely and effective communication about end-of-life issues, including conversations about prognosis and goals of care, are extremely beneficial to terminally ill patients and their families. However, given the context, healthcare professionals may find it challenging to initiate and facilitate such conversations. Hence, it is critical to improving the available communication strategies to enhance end-of-life communication practices. AIM: To summarise the end-of-life communication strategies recommended for healthcare professionals, identify research gaps and inform future research. DESIGN: A scoping review performed in accordance with the Arksey and O'Malley framework. DATA SOURCES: A literature search was conducted between January 1990 and January 2022 using PubMed, CINAHL, Embase, PsycINFO, Web of Science, Scopus, Cochrane Library and China National Knowledge Infrastructure databases and Google, Google Scholar and ProQuest Dissertations & Theses Global. Studies that described recommended end-of-life communication strategies for healthcare professionals were included. RESULTS: Fifty-nine documents were included. Seven themes of communication strategies were found: (a) preparation; (b) exploration and assessment; (c) family involvement; (d) provision and tailoring of information; (e) empathic emotional responses; (f) reframing and revisiting the goals of care; and (g) conversation closure. CONCLUSIONS: The themes of communication strategies found in this review provide a framework to integrally promote end-of-life communication. Our results will help inform healthcare professionals, thereby promoting the development of specialised training and education on end-of-life communication.

OBJECTIVE: To compare barriers and facilitators to accessing health care services among service members and veterans (SMVs) by traumatic brain injury (TBI) severity groups. DESIGN: Qualitative descriptive study guided by an access to health care services conceptual framework. SETTING: Five Veterans Affairs (VA) polytrauma rehabilitation centers. PARTICIPANTS: SMVs (N=55, including 10 caregivers as proxies) ≥2 years post-TBI recruited from the VA TBI Model Systems and grouped by TBI severity (mild/moderate, severe). MAIN OUTCOME MEASURES: Barriers and facilitators accessing care. RESULTS: The main facilitators included ease of communicating with providers to help SMVs identify and utilize appropriate health care, family advocates who promoted engagement in health care, ability to use government and community facilities, and online resources or equipment. Distance to services was uniformly identified as a main barrier for both patient groups. However, facilitators and barriers to health care access differed by TBI severity. SMVs with severe TBI highlighted the role of nonprofit organizations in promoting health care engagement and the availability of VA specialty residential programs in meeting health care needs. Having unrecognized health care needs in chronic stages and communication difficulties with providers were more commonplace for those with greater TBI severity and affected quality of care. Those with mild/moderate TBI highlighted challenges associated with paying for services in the community and scheduling of services. CONCLUSIONS: Barriers and facilitators exist across multiple dimensions of a health care access framework and vary by TBI severity. Results suggest possible mechanistic links between health care access and SMV health outcomes. Findings support current policy and practice efforts to facilitate health care access for SMVs with TBI but highlight the need for tailored approaches for those with greater disability.

OBJECTIVE: The construct of participation after traumatic brain injury (TBI) can be difficult to operationalize. Psychometric network analysis offers an empirical approach to visualizing and quantifying the associations between activities that comprise participation, elucidating the relations among the construct's components without assuming the presence of a latent common cause and generating a model to inform future measurement methods. The current research applied psychometric network analysis to the Participation Assessment with Recombined Tools-Objective (PART-O) within a sample of service members and veterans (SM/Vs) with a history of TBI at 1 and 2 years ( T1 and T2 ) postinjury. PARTICIPANTS: Participants ( N = 663) were SM/Vs with a history of TBI who completed comprehensive inpatient rehabilitation services at a Department of Veterans Affairs (VA) Polytrauma Rehabilitation Center (PRC). SETTING: Five VA PRCs. DESIGN: Cross-sectional, retrospective analysis of data from the VA TBI Model Systems study. MAIN MEASURES: PART-O. RESULTS: Network analysis demonstrated that the PART-O structure was generally consistent over time, but some differences emerged. The greatest difference observed was the association between "spending time with friends" and "giving emotional support" to others. This association was more than twice as strong at T2 as at T1 . The "out of the house" item was most central, as demonstrated by dense connections within its own subscale (Out and About) and items in other subscales (ie, Social Relations and Productivity). When examining items connecting the 3 subscales, the items related to giving emotional support, internet use, and getting out of the house emerged as the strongest connectors at T1 , and the internet was the strongest connector at T2 . CONCLUSION: Providing emotional support to others is associated with greater participation across multiple domains and is an important indicator of recovery. Being out and about, internet use, and engagement in productive activities such as school and work shared strong associations with Social Relations. Network analysis permits visual conceptualization of the dynamic constructs that comprise participation and has the potential to inform approaches to measurement and treatment.

BACKGROUND: A substantial proportion of persons who develop COVID-19 report persistent symptoms after acute illness. Various pathophysiologic mechanisms have been implicated in the pathogenesis of postacute sequelae of SARS-CoV-2 infection (PASC). OBJECTIVE: To characterize medical sequelae and persistent symptoms after recovery from COVID-19 in a cohort of disease survivors and controls. DESIGN: Cohort study. (ClinicalTrials.gov: NCT04411147). SETTING: National Institutes of Health Clinical Center, Bethesda, Maryland. PARTICIPANTS: Self-referred adults with laboratory-documented SARS-CoV-2 infection who were at least 6 weeks from symptom onset were enrolled regardless of presence of PASC. A control group comprised persons with no history of COVID-19 or serologic evidence of SARS-CoV-2 infection, recruited regardless of their current health status. Both groups were enrolled over the same period and from the same geographic area. MEASUREMENTS: All participants had the same evaluations regardless of presence of symptoms, including physical examination, laboratory tests and questionnaires, cognitive function testing, and cardiopulmonary evaluation. A subset also underwent exploratory immunologic and virologic evaluations. RESULTS: 189 persons with laboratory-documented COVID-19 (12% of whom were hospitalized during acute illness) and 120 antibody-negative control participants were enrolled. At enrollment, symptoms consistent with PASC were reported by 55% of the COVID-19 cohort and 13% of control participants. Increased risk for PASC was noted in women and those with a history of anxiety disorder. Participants with findings meeting the definition of PASC reported lower quality of life on standardized testing. Abnormal findings on physical examination and diagnostic testing were uncommon. Neutralizing antibody levels to spike protein were negative in 27% of the unvaccinated COVID-19 cohort and none of the vaccinated COVID-19 cohort. Exploratory studies found no evidence of persistent viral infection, autoimmunity, or abnormal immune activation in participants with PASC. LIMITATIONS: Most participants with COVID-19 had mild to moderate acute illness that did not require hospitalization. The prevalence of reported PASC was likely overestimated in this cohort because persons with PASC may have been more motivated to enroll. The study did not capture PASC that resolved before enrollment. CONCLUSION: A high burden of persistent symptoms was observed in persons after COVID-19. Extensive diagnostic evaluation revealed no specific cause of reported symptoms in most cases. Antibody levels were highly variable after COVID-19.

Context: Studies have found evidence for meditation's positive effects on health and well-being, but the difficulty of learning and engaging in meditation practice has been identified as a major barrier. Virtual reality (VR) technology may facilitate meditation practice by immersing users in a distraction-free and calming virtual environment, although this theory has yet to be rigorously tested. Objective: This study intended to examine the efficacy of VR-guided meditation in a population of US veterans as a tool to facilitate meditation and relaxation practice for reduction of stress and chronic pain as well as to elicit participants' feedback regarding their perceptions of VR-guided meditation. Design: The research team designed a preliminary study to identify the scope of future investigations. Setting: The study was conducted at an outpatient polytrauma clinic in a Veterans Affairs (VA) Palo Alto Health Care System, located in Palo Alto, California. Participants: Participants were a convenience sample of 31 veterans, with an average age of 55.2 years, who were patients at the polytrauma clinic and who had conditions with varying levels of stress and chronic pain. Intervention: All participants completed a 10-minute, VR-guided-meditation session based on the Zen form of meditation. Outcome Measures: At baseline immediately before and postintervention immediately after the VR meditation session, self-report ratings of pain and stress, physiological measures testing heart rate (HR) and blood pressure (BP), and participants' survey responses that assessed their experiences with, attitudes toward, and concerns about VR for clinical therapy were obtained. Results: Participants showed statistically significant reductions in self-reported pain and stress, HR, and systolic and diastolic BP. Participants reported high satisfaction with VR-guided meditation, and few reported negative side-effects. Conclusions: The study provided evidence for the usefulness of VR technology as a facilitator of meditation practice for reduction of stress and chronic pain. Future studies are needed to examine the long-term effects of repeated VR-guided-meditation sessions for patients with stress and chronic pain.

OBJECTIVE: This study analyzed the data collected using a headache diary mobile application to characterize posttraumatic headaches (PTHs) in a sample of US veterans. Specifically, we measured patient engagement with the mobile application and compared our findings with previous literature regarding PTHs. SETTING: A Headache Center of Excellence (HCoE) in a Veterans Health Administration facility. PARTICIPANTS: Forty-nine veterans currently being treated for ongoing PTH-related complaints with English fluency, reliable access to the internet, and a mobile phone. DESIGN: Observational study of PTH characteristics using the mobile application over the course of 1 year. MEASURES: Main outcome measures were collected via a headache diary mobile application developed for patients to track headache-associated symptoms, headache location, triggers, type, intensity, and duration. Patients also completed a baseline Headache Impact Test (HIT-6) survey. RESULTS: In total, 1569 entries were completed during the first year of application deployment. On average, patients completed 2.5 entries per week and used the application for 70 days. They frequently reported associated PTH symptoms of photophobia (56.7%) and headaches triggered by emotional stress (35.1%). Network analyses revealed patterns of co-occurrence in triggers of headache pain, associated symptoms, and headache pain location. Headache pain severity and impact ratings from the headache diary demonstrated convergent validity with the established HIT-6 measure. CONCLUSIONS: Headache diary mobile applications are a promising tool for monitoring and characterizing PTHs in veterans. Present results mirror past studies of PTH characteristics. Mobile application headache diaries may be used in both clinical and research settings to monitor headache symptoms and communicate the functional impact of headaches in real time.

OBJECTIVE: To describe alcohol use among younger military active duty service members and veterans (SMVs) in the first 5 years after traumatic brain injury (TBI) and examine whether differential alcohol use patterns emerge as a function of brain injury severity and active duty service at time of injury. SETTING: Veterans Affairs (VA) Polytrauma Rehabilitation Centers (PRCs). PARTICIPANTS: In total, 265 SMVs enrolled in the VA Traumatic Brain Injury Model Systems (TBIMS) PRC national database. Participants sustained a TBI of any severity level; received inpatient care at a PRC within 1 year of injury; were younger than 40 years; and completed survey interviews or questionnaires regarding their pre- and postinjury alcohol use for at least 3 of 4 time points (preinjury, postinjury years 1, 2, and 5). MAIN MEASURES: Self-reported alcohol use, defined as amount of weekly consumption and endorsement of binge drinking. Participant information related to demographics, injury, TBI severity, active duty status, mental health treatment, and FIM (Functional Independence Measure) total scores was also obtained to examine impact of these as covariates in the analyses. RESULTS: Alcohol use generally increased following an initial period of reduced consumption for SVMs with moderate-to-severe TBI. Individuals with mild TBI showed an opposite trend, with an initial period of increased use, followed by a decline and return to baseline levels in the long term. However, alcohol use did not significantly differ over time within this subsample after adjusting for covariates. CONCLUSIONS: The current study identified longitudinal alcohol use among a young, military/veteran cohort with a history of TBI, an at-risk population for problematic alcohol use. Patterns of self-reported alcohol consumption suggest the time frame of 2 to 5 years postinjury may be a critical window of opportunity for further intervention to maintain lowered levels of alcohol use, particularly among SVMs with moderate-to-severe TBI.

BACKGROUND: A clinical handover is an essential nursing practice that ensures patient safety. However, most newly graduated nurses struggle to conduct clinical handovers as they lack sufficient communication skill competence and self-efficacy in this practice. This study aimed to examine the efficacy of a blended learning programme on the communication skill competence and self-efficacy of final-year nursing students in conducting clinical handovers. METHODS: A randomised controlled design was used. A convenience sample of 96 final-year baccalaureate nursing students at a local university. Data were collected in 2020. Participants were randomly assigned to either an experimental group (n = 50) that received a blended learning programme with face-to-face training and an online module on handover practice, or a waitlist control group (n = 46) that received only face-to-face handover training during the study period and an online module immediately after the completion of data collection. The primary outcome was the communication skill competence and the secondary outcome was the self-efficacy of the participants in conducting clinical handovers. An analysis of covariance was used to examine the between-subjects effects on self-efficacy and communication skill competence in conducting clinical handovers after controlling for the significantly correlated variables. A paired sample t-test was used to determine the within-subjects effects on self-efficacy. RESULTS: The participants in the experimental group had significantly higher communication skill competence (p < 0.001) than those in the waitlist control group. Although both groups showed a significant improvement in self-efficacy, the mean scores of the experimental group were higher than those of the waitlist control group (p < 0.001). CONCLUSIONS: This study demonstrated the efficacy of a blended learning approach in improving the communication skill competence and self-efficacy of final-year nursing students in conducting clinical handovers. Nurse educators should incorporate a blended learning approach into the nursing curriculum to optimise the content of training programmes for teaching nursing students in conducting clinical handovers. TRIAL REGISTRATION: The study protocol was registered in the Registration ClinicalTrials.gov ( NCT05150067 ; retrospective registration; date of registration 08/12/2021).

OBJECTIVE: To examine the interrelationships among resilience, self-esteem, and depressive symptoms and determine whether resilience was a factor associated with quality of life for Hong Kong Chinese children with cancer. METHODS: We used a cross-sectional study design. Participants were 138 Hong Kong Chinese children (aged 7-14 years) who were admitted to the pediatric oncology units of an acute public hospital. The resilience, depressive symptoms, self-esteem, and quality of life of participating children were assessed. The primary outcome was the association between resilience and quality of life in children with cancer. RESULTS: In total, 72 boys and 66 girls were recruited for this study (mean age 10.6 years). The mean levels of resilience, depressive symptoms, self-esteem, and quality of life were 23.4, 30.0, 23.0, and 63.6, respectively. There was a statistically significant strong positive correlation between resilience and quality of life (r = 0.60, p < 0.01), indicating that greater resilience was associated with better quality of life. Children with cancer from single-parent families, those diagnosed with a brain tumor, and those who received multiple treatments reported significantly lower levels of resilience, self-esteem, and quality of life, and greater depressive symptoms than other children (all p's < 0.001). Results of a multiple regression analysis revealed that resilience (p < 0.001) was a strong factor associated with quality of life among children with cancer. CONCLUSIONS: It is essential that healthcare professionals implement interventions to boost the resilience of children with cancer, thereby enhancing their quality of life.

BACKGROUND: To test the psychometric properties of a traditional Chinese version of the Resilience Scale for Children (RS-10) and examine its factorial structure via a confirmatory factor analysis (CFA). METHODS: One hundred and eighty-six Hong Kong Chinese children with cancer were recruited in the paediatric oncology units of two public acute-care hospitals in Hong Kong to participate in this cross-sectional study. The psychometric properties of the traditional Chinese version of the RS-10 were assessed, namely its content equivalence, convergent and discriminant validity, construct validity, internal consistency and test-retest reliability. RESULTS: The newly translated traditional Chinese version of the RS-10 demonstrated adequate internal consistency (Cronbach's α = .83, McDonald's Ω = .80), excellent test-retest reliability (.89), good content equivalence (CVI = 96%) and appropriate convergent (r = - .52, P = .01) and discriminant validity (r = .61, P = .01). The CFA results demonstrated that there was a good fit between the factor structure of the Chinese version of the RS-10 and the observed data (χ2/df = 2.34, TLI = .951, RMSEA = .053, CFI = .962, GFI = .948, SRMR = .052), thereby confirming the construct validity of this instrument. CONCLUSIONS: The traditional Chinese version of the RS-10 was found to be a reliable and valid tool for assessing the resilience of Hong Kong Chinese children with cancer. The newly developed traditional Chinese version of the RS-10 is an appropriate clinical research tool for evaluating the effectiveness of nursing interventions in enhancing the resilience of and promoting mental well-being in children with cancer. Trial registration NCT03544190.

PURPOSE: Musical training has been found to promote psychological well-being and quality of life among pediatric brain tumor survivors. Yet, the essential elements of musical training that influence its efficacy remain unknown. This study aimed to examine the lived experience of engaging in the musical training program from the perspectives of pediatric brain tumor survivors, their parents, and interveners. METHODS: We employed a descriptive phenomenological approach. Twenty pediatric brain tumor survivors (aged 8-15 years) who had undergone musical training in a previous trial were selected, along with their parents (13 mothers and 7 fathers) and 7 interveners, to participate in individual semi-structured interviews. Data analysis was conducted according to Colaizzi's descriptive phenomenology method. RESULTS: Five main themes emerged from the interviews: overcoming difficulties encountered during the initial phase of the musical training program, improved psychological and emotional well-being, facilitation of participation in musical training program, appreciation of the benefits of joining the musical training program, and expectation of future musical training program. The musical training program improved the psychological and emotional well-being of pediatric brain tumor survivors by promoting positive mood, facilitating emotional management and expression, and enhancing self-confidence. In addition, learning in a supportive environment is crucial in facilitating survivors to overcome adversity during their learning process. CONCLUSION: This study addressed a literature gap by exploring how a musical training program promoted psychological well-being among pediatric brain tumor survivors. The study findings inform the importance of tailoring musical training program based on survivors' learning abilities and needs.

During differentiation of the Tetrahymena thermophila somatic nucleus, its germline-derived DNA undergoes extensive reorganization including the removal of â¼50 Mb from thousands of loci called internal eliminated sequences (IESs). IES-associated chromatin is methylated on lysines 9 and 27 of histone H3, marking newly formed heterochromatin for elimination. To ensure that this reorganized genome maintains essential coding and regulatory sequences, the boundaries of IESs must be accurately defined. In this study, we show that the developmentally expressed protein encoded by Lia3-Like 1 (LTL1) (Ttherm_00499370) is necessary to direct the excision boundaries of particular IESs. In ΔLTL1 cells, boundaries of eliminated loci are aberrant and heterogeneous. The IESs regulated by Ltl1 are distinct from those regulated by the guanine-quadruplex binding Lia3 protein. Ltl1 has a general affinity for double stranded DNA (Kd â¼ 350 nM) and binds specifically to a 50 bp A+T rich sequence flanking each side of the D IES (Kd â¼ 43 nM). Together these data reveal that Ltl1 and Lia3 control different subsets of IESs and that their mechanisms for flanking sequence recognition are distinct.

OBJECTIVE: To identify predictors of driving status in service members and veterans 1 year following a traumatic brain injury (TBI). SETTING: The 5 Department of Veterans Affairs (VA) Polytrauma Rehabilitation Centers (PRCs). PARTICIPANTS: A total of 471 service members and veterans (128 with mild/complicated mild TBI and 343 with moderate/severe TBI) who received TBI-focused inpatient rehabilitation at one of the VA PRCs and who participated in a 1-year postinjury follow-up assessment. DESIGN: Secondary analysis from the Department of Veterans Affairs Polytrauma Rehabilitation Centers Traumatic Brain Injury Model Systems (VA PRC TBIMS) national database. MAIN MEASURES: Primary outcome was a single item that assessed driving status at 1 year postinjury. Predictor variables included demographics; sensory impairment, substance use, and employment status at time of injury; PTSD symptoms reported at study enrollment; and functional impairment rated at rehabilitation discharge. RESULTS: In unadjusted bivariate analyses, among those with a mild/complicated mild TBI, older age and greater functional impairment were associated with lower likelihood of driving. Among those with a moderate/severe TBI, discharge to a nonprivate residence, greater functional impairment, and higher PTSD symptoms were linked to lower likelihood of driving. Adjusted multivariate analyses indicated that functional impairment was uniquely associated with driving status in both TBI severity groups. After controlling for other predictors, self-reported PTSD symptoms, particularly dysphoria symptoms, were associated with lower likelihood of driving in both severity groups. CONCLUSION: Given the significance of clinician-rated functional impairment and self-reported PTSD symptoms to the prediction of driving status 1 year post-TBI among service members and veterans, rehabilitation efforts to improve functioning and reduce negative affect may have a positive impact on driving and community integration.

OBJECTIVE: Describe rehabilitation needs and factors associated with unmet needs at 5 years post-traumatic brain injury (TBI). SETTING: Five Veterans Affairs (VA) polytrauma rehabilitation centers (PRCs). PARTICIPANTS: VA TBI Model Systems participants (N = 283; 96% male, 75%, 57% severe TBI). DESIGN: Prospective observational cohort. MAIN MEASURES: Rehabilitation Needs Survey (21-item survey that assesses cognitive, emotional, social, and functional needs); Craig Hospital Inventory of Environmental Factors (25-item survey of potential environmental barriers). RESULTS: Participants endorsed a mean of 8 (SD: 6.2) ongoing and 3 (SD: 4.7) unmet rehabilitation needs at 5 years post-TBI. Approximately 65% of participants reported at least 1 rehabilitation need that remained unmet. The number and nature of needs differed across TBI severity groups. In unadjusted and adjusted linear regression models, Black race and environmental barriers (Craig Hospital Inventory of Environmental Factors total score) were predictive of unmet needs (P < .001). Those with greater unmet needs reported the physical environment (54%-63%), informational sources (54%), social attitudes (55%), healthcare access (40%), public policy (32%-37%), transportation availability (33%), and in-home assistance (32%) as the most frequent environmental barriers at 5 years post-TBI. CONCLUSION: Veterans and Service Members continue to have rehabilitation needs at 5 years post-TBI. Veterans Affairs programs to address ongoing needs and policy to support them are needed.

There is growing concern about mental health problems among juveniles. Evidence shows that adventure-based training can reduce depressive symptoms in school children. However, a rigorous empirical investigation of the effectiveness of such training in enhancing resilience among juveniles has not yet been performed. In this study, a randomized controlled trial was conducted to examine the effectiveness of adventure-based training in enhancing resilience and self-esteem and reducing depressive symptoms among juveniles. Secondary school students from grades 7 to 9 (aged 12-16 years) who attended the Integrated Children and Youth Services Centre in a large public housing estate in Hong Kong from December 20, 2018 to November 25, 2019 were invited to participate in this study. We randomly assigned 228 eligible adolescents to an experimental group (n = 115) that received a 2-day/1-night adventure-based training or a placebo control group (n = 113) that received 2 days of leisure activities organized by the Integrated Children and Youth Services Centre. Data were collected at baseline and 3 and 6 months after the corresponding interventions. The primary outcome was resilience at 6 months. The secondary outcomes were depressive symptoms and self-esteem at 6 months. Compared with the placebo control group, the experimental group showed significantly higher resilience (p = 0.001) and fewer depressive symptoms (p = 0.02) at 6 months, and significantly higher self-esteem at 3 months (p = 0.04), but not at 6 months (p = 0.12). However, the generalizability of the findings is limited as we used a convenience sample.

BACKGROUND: Patients undergoing total joint arthroplasty (TJA) have an increased likelihood of having an abnormal coagulation profile compared with the general population. Coagulation abnormalities are often screened for before surgery and considered during perioperative planning. This study assesses a preoperative abnormal coagulation profile as a risk factor for postoperative complications after total hip arthroplasty (THA), revision THA (rTHA), total knee arthroplasty (TKA), and revision TKA (rTKA) and then examines specific coagulopathies to determine their influence on complication rates. METHODS: Patients who underwent THA, rTHA, TKA, or rTKA from 2011 to 2017 were identified in the American College of Surgeons National Surgical Quality Improvement Program database and then assessed for preoperative abnormal coagulation profiles. Various postoperative complications were analyzed for each cohort, and two separate multivariate regression analyses were used to assess the relationship between abnormal coagulation and postoperative complications. RESULTS: 403,566 THA, rTHA, TKA, or rTKA cases were identified, and 40,466 (10.0%) of patients were found to have an abnormal coagulation profile. Patients with preoperative coagulation abnormalities had higher likelihoods of postoperative complications after primary TJA than in revision TJA. An international normalized ratio>1.2 was associated with the most types of postoperative complications, followed by a bleeding disorder diagnosis. A partial thromboplastin time>35 seconds was associated with only one type of postoperative complication, while a platelet count <150,000 per µL was associated with postoperative complications only after TKA. CONCLUSION: TJA in patients with abnormal coagulation profiles may result in adverse outcomes. These patients may benefit from preoperative intervention. Prophylactic care needs to be personalized to the specific coagulation abnormalities present.

BACKGROUND: Wallerian degeneration (WD) following peripheral nerve injury (PNI) is an area of growing focus for pharmacological developments. Clinically, WD presents challenges in achieving full functional recovery following PNI, as prolonged denervation of distal tissues for an extended period of time can irreversibly destabilize sensory and motor targets with secondary tissue atrophy. Our objective is to improve upon histological assessments of WD. METHODS: Conventional methods utilize a qualitative system simply describing the presence or absence of WD in nerve fibers. We propose a three-category assessment that allows more quantification: A fibers appear normal, B fibers have moderate WD (altered axoplasm), and C fibers have extensive WD (myelin figures). Analysis was by light microscopy (LM) on semithin sections stained with toluidine blue in three rat tibial nerve lesion models (crush, partial transection, and complete transection) at 5 days postop and 5 mm distal to the injury site. The LM criteria were verified at the ultrastructural level. This early outcome measure was compared with the loss of extensor postural thrust and the absence of muscle atrophy. RESULTS: The results showed good to excellent internal consistency among counters, demonstrating a significant difference between the crush and transection lesion models. A significant decrease in fiber density in the injured nerves due to inflammation/edema was observed. The growth cones of regenerating axons were evident in the crush lesion group. CONCLUSION: The ABC method of histological assessment is a consistent and reliable method that will be useful to quantify the effects of different interventions on the WD process.

BACKGROUND: A reliable and valid instrument that accurately measures resilience is crucial for the development of interventions to enhance the resilience of adolescents and promote their positive mental well-being. However, there is a lack of adolescent resilience assessment tools with good psychometric properties suitable for use with Hong Kong participants. This study aimed to evaluate the psychometric properties of the traditional Chinese version of the Resilience Scale-14. METHODS: Between October 2017 and January 2018, a stratified random sample of 1816 Grade 7 (aged 11-15 years) students from all 18 districts of Hong Kong were invited to participate in the study. Subjects were asked to respond to the traditional Chinese version of the Resilience Scale-14, the Center for Epidemiologic Studies Depression Scale for children, and Rosenberg's Self-Esteem Scale. The psychometric properties, including the internal consistency, content validity, convergent and discriminant validity, exploratory and confirmatory factor analyses, and test-retest reliability of the Resilience Scale-14 were assessed. RESULTS: The translated scale demonstrated good internal consistency and test-retest reliability, excellent content validity, and appropriate convergent and discriminant validity. The results of the confirmatory factor analysis supported the two-factor structure of the traditional Chinese version of the Resilience Scale-14. CONCLUSIONS: Results suggest that the translated scale is a reliable and valid tool to assess the resilience of young Hong Kong Chinese adolescents. Healthcare professionals could use the newly translated scale to assess resilience levels among Hong Kong adolescents and develop interventions that can help them combat mental health problems and lead healthier lives.
