INTRODUCTION
The management of Factor XI deficiency is challenged by a variable association between FXI level and bleeding phenotype. Additionally, there is scarce data describing management strategies and their outcomes, specifically bleeding, thrombosis, and other complications.
AIMS
To evaluate bleeding, thrombosis, and other complications in individuals with severe FXI deficiency seen in our comprehensive haemophilia treatment centre (HTC). Peri-procedural management strategies and the resulting impact on bleeding and other clinically relevant outcomes were reported.
METHODS
Retrospective review of the electronic medical record of adult patients with severe FXI deficiency (< 20% activity) seen at a New York City comprehensive HTC between 2017 and 2022. Procedures, haemostatic management, and outcomes were collected and analysed.
RESULTS
We identified 38 individuals (64%) females with severe FXI deficiency. The mean age was 56 ± 21 years (SD). The median FXI activity level was 3% (IQR: 1-8%). The mean BAT score was 3.1 ± 2.4; (52%) individuals did not have a history of bleeding. A total of 256 surgeries and procedures were performed. There was reduced bleeding with preventative or reactive treatment during procedures. Arterial but not venous thrombotic complications were observed. Plasma was mostly used for procedures associated with higher risk of bleeding and antifibrinolytics for procedures at sites of high fibrinolysis.
CONCLUSIONS
Current management strategies pose a burden of care for these patients and manifested as nonbleeding adverse events and changes in clinical management. These findings highlight the need for novel investigation in predicting and managing bleeding for individuals with severe FXI deficiency.

INTRODUCTION
The estimated prevalence of postpartum depression (PPD) worldwide, in China, and Shanghai is 17.2%, 18.0% and 23.2%, respectively. In 2021, Shanghai housed a population of 3.2 million childbearing-age migrant women, most of whom migrated to the city with their husbands for economic reasons. There is a general lack of help-seeking behaviour for mental disorders in China due to the perceived risk of social stigmatisation. In Shanghai, 70% of women did not seek professional help for perinatal mental health problems. We aim to gather information from multiple perspectives, such as the migrant women with PPD and perinatal depression (PND), their caregivers, health service providers and communities, to understand the help-seeking behaviour of postpartum migrant women with PPD or PND in China.
METHODS AND ANALYSIS
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework for Scoping Reviews will guide this review. A bilingual research librarian developed a comprehensive search strategy to retrieve published and unpublished English and Chinese studies involving factors influencing women's PPD or PND help-seeking behaviour in China. This literature includes perceptions, views, patterns, acceptance and refusal, tendencies, probability, service accessibility and utilisation, and facts. We will search PubMed, Embase, Web of Science and CINAHL for English literature and CINKI for Chinese literature. Backward and forward snowball approaches will be used to identify additional relevant papers from the reference lists of selected papers. Two independent reviewers will screen the title and abstract and review the full text of selected papers to identify eligible articles for data extraction. We will build a Microsoft Access database to record the extracted data. The results will be presented in tables and a causal map to demonstrate the relationships between extracted variables and help-seeking behaviours for PPD and PND. A conceptual simulation model will be formulated based on the information from the literature to validate the logic of the relationships between variables, identify knowledge gaps and gain insights into potential intervention approaches. Experts and stakeholders will be invited to critique and comment on the results during group model building (GMB) workshops in Shanghai. These comments will be essential to validate the findings, receive feedback and obtain additional insights.
ETHICS AND DISSEMINATION
The literature review component of our study does not require ethical approval because the information and data collected will be obtained from publicly available sources and will not involve human subjects. Our collaborating research partner, International Peach Maternal Child Hospital, obtained the IRB approval (GKLW-A-2023-020-01) for screening and enrolling participants in GMB workshops. Stanford University received IRB approval under protocol number 67 419. The full review will be presented at a relevant conference and submitted to a peer-reviewed scientific journal for publication to report findings.

INTRODUCTION
Persistent symptoms after mild traumatic brain injury (mTBI) negatively affect daily functioning and quality of life. Fear avoidance behaviour, a coping style in which people avoid or escape from activities or situations that they expect will exacerbate their symptoms, maybe a particularly potent and modifiable risk factor for chronic disability after mTBI. This study will evaluate the efficacy of graded exposure therapy (GET) for reducing persistent symptoms following mTBI, with two primary aims: (1) To determine whether GET is more effective than usual care; (2) to identify for whom GET is the most effective treatment option, by evaluating whether baseline fear avoidance moderates differences between GET and an active comparator (prescribed aerobic exercise). Our findings will guide evidence-based care after mTBI and enable better matching of mTBI patients to treatments.
METHODS AND ANALYSIS
We will conduct a multisite randomised controlled trial with three arms. Participants (n=220) will be recruited from concussion clinics and emergency departments in three Canadian provinces and randomly assigned (1:2:2 ratio) to receive enhanced usual care, GET or prescribed aerobic exercise. The outcome assessment will occur remotely 14-18 weeks following baseline assessment, after completing the 12-week treatment phase. The primary outcome will be symptom severity (Rivermead Post-concussion Symptoms Questionnaire).
ETHICS AND DISSEMINATION
Informed consent will be obtained from all participants. All study procedures were approved by the local research ethics boards (University of British Columbia Clinical Research Ethics Board, University of Calgary Conjoint Health Research Ethics Board, University Health Network Research Ethics Board-Panel D). Operational approvals were obtained for Vancouver Coastal Health Research Institute and Provincial Health Services Authority. If GET proves effective, we will disseminate the GET treatment manual and present instructional workshops for clinicians.

Review
Herpes zoster (HZ) incidence is much higher in immunocompromised individuals than in immunocompetent individuals. HZ also occurs at a younger age and is often more severe in immunocompromised persons. Preventive strategies center around the recombinant zoster vaccine (RZV), which is approved for immunocompromised adults age 19 and older. Identifying those at greatest risk is critical. For those considering vaccination, evidence gaps regarding vaccine efficacy, toxicity, length of protection, and potential effects on underlying conditions may complicate shared and informed decision-making. Recent data have filled some of these gaps, with several societies issuing recommendations regarding vaccination. Remaining gaps are currently addressed by expert opinion.

Review
Rheumatoid arthritis (RA) is prevalent in many Indigenous North American First Nations (FN) and tends to be seropositive, familial, and disabling, as well as associated with highly unfavorable outcomes such as early mortality. The risk of developing RA is based on a perfect storm of gene-environment interactions underpinning this risk. The gene-environment interactions include a high frequency of shared epitope encoding HLA alleles, particularly , in the background population, and prevalent predisposing environmental factors such as smoking and periodontal disease. Together, these provide a compelling rationale for an RA prevention agenda in FN communities. Our research team has worked in partnership with several FN communities to prospectively follow the first-degree relatives of FN patients with RA, with the aim of better understanding the preclinical stages of RA in this population. We have focused on specific features of the anticitrullinated protein antibodies (ACPA) and other proteomic biomarkers as predictors of future development of RA. These studies have now led us to consider interventions having a favorable risk-benefit ratio if applied at a stage prior to a hypothetical "point of no return," when the autoimmunity potentially becomes irreversible. Based on a supportive mouse model and available human studies of curcumin, omega-3, and vitamin D supplements, we are undertaking studies where we screen communities using dried blood spot technology adapted for the detection of ACPA, and then enrolling ACPA-positive individuals in studies that use a combination of these supplements. These studies are guided by shared decision-making principles.

BACKGROUND
Diagnostic testing is prevalent among children with persistent non-specific symptoms (PNS), and both undertesting and overtesting have negative consequences for child and society. Research in adults with PNS has shown that general practitioners (GPs) use diagnostic testing for reasons other than diagnosis, but comparable research has not been conducted in children. Understanding GPs' perspectives of testing decisions in children could provide insights into mechanisms of undertesting and overtesting.
AIM
To investigate GPs' perspectives of conducting or refraining from diagnostic testing in children with PNS, and differences with motives in adults.
DESIGN AND SETTING
Qualitative study using semi-structured interviews with Dutch GPs.
METHOD
We purposively sampled GPs until data saturation. Reasons for conducting or refraining from diagnostic tests were explored using two real-life cases from daily practice. Online video interviews were transcribed verbatim. Data were collected and analyzed concurrently by thematic content analysis.
FINDINGS
Twelve GPs participated. Their decision-making involved a complex trade-off among four themes: medical (e.g., alarm symptoms), psychosocial (e.g., doctor-patient relationship), consultation management (e.g., 'quick fix'), and efficient resource utilization (e.g., sustainability). Compared to adults, GPs were more hesitant to conduct diagnostic testing in children due to their higher vulnerability to fearing invasive procedures, lower probability of organic disease, and reduced autonomy.
CONCLUSION
As in adults, GPs' decisions to conduct diagnostic tests in children were motivated by reasons beyond diagnostic uncertainty. Educational programs, interventions, and guidelines that aim to change the testing behaviors of GPs in children with PNS should target these reasons as well.

Marine ecosystems are under escalating threats from myriad environmental stressors, necessitating a deeper understanding of their impact on biodiversity and the health of sentinel organisms. In this study, we carried out a spatiotemporal multi-omic analysis of liquid biopsies collected from mussels (Mytilus spp.) in marine ecosystems of a national park. We delved into the epigenomic, transcriptomic, glycomic, proteomic, and microbiomic profiles to unravel the intricate interplay between ecosystem biodiversity and mussels' biological response to their environments. Our analysis revealed temporal fluctuations in the alpha diversity of the circulating microbiome associated with human activities. Analysis of the hemolymphatic circulating cell-free DNA (ccfDNA) provided information on the biodiversity and the presence of potential pathogens. Epigenomic analysis revealed widespread hypomethylation sites within the mitochondrial (mtDNA). Comparative transcriptomic and glycomic analyses highlighted differences in metabolic pathways and genes associated with immune and wound healing functions. This study demonstrates the potential of multi-omic analysis of liquid biopsy in sentinel to provide a holistic view of human activities' environmental impacts on marine coastal ecosystems. Overall, this approach has the potential to enhance the effectiveness and efficiency of various conservation efforts, leading to more informed decision-making and better outcomes for biodiversity and ecosystem conservation.

OBJECTIVE
As health-related social needs (HRSN) screening increases, attention to families' resource preferences lags. This study of a pediatric primary care intervention (DULCE) with reliable HRSN screening and resource connection explored whether resources adequately addressed families' needs and, when HRSN persisted, families' reasons for declining resources.
METHODS
This retrospective cohort, mixed-methods study analyzed data from 989 families that received care at seven pediatric clinics implementing DULCE in three states. DULCE screens for seven HRSN around the 1-month and 4-month well-child visits; we calculated the percent of initial and ongoing positive screens. For positive rescreens, we calculated the percent that had all eligible or wanted resources and that were interested in further resources. We also analyzed case notes, which elicited families' resource preferences, and explored demographic characteristics associated with ongoing HRSN.
RESULTS
Half of enrolled families (508 of 989) initially screened positive for HRSN; 124 families had positive rescreens; 26 expressed interest in further assistance. Most families with ongoing concrete supports needs accessed all eligible resources (60-100%); 20-58% had everything they wanted. Fewer families with ongoing maternal depression and intimate partner violence accessed all eligible resources (48% and 18%, respectively); most reported having all wanted resources (76% and 90%, respectively). Families declined resources due to lack of perceived need, the HRSN resolving, or families addressed HRSN themselves. White families were more likely to rescreen positive.
CONCLUSIONS
Pediatric medical homes must honor family-centered decision-making while empowering families to accept beneficial resources. Healthcare systems should advocate for resources that families need and want.

BACKGROUND
The Society of Thoracic Surgeons General Thoracic Surgery Database (STS-GTSD) previously reported short-term risk models for esophagectomy for esophageal cancer. We sought to update existing models using more inclusive contemporary cohorts, with consideration of additional risk factors based on clinical evidence.
METHODS
The study population consisted of adult patients in the STS-GTSD who underwent esophagectomy for esophageal cancer between January 2015 and December 2022. Separate esophagectomy risk models were derived for three primary endpoints: operative mortality, major morbidity, and composite morbidity or mortality. Logistic regression with backward selection was used with predictors retained in models if p<0.10. All derived models were validated using 9-fold cross validation. Model discrimination and calibration were assessed for the overall cohort and specified subgroups.
RESULTS
A total of 18,503 patients from 254 centers underwent esophagectomy for esophageal cancer. Operative mortality, morbidity, and composite morbidity or mortality rates were 3.4%, 30.5% and 30.9%, respectively. Novel predictors of short-term outcomes in the updated models included body surface area and insurance payor type. Overall discrimination was similar or superior to previous GTSD models for operative mortality [C-statistic = 0.72] and for composite morbidity or mortality [C-statistic = 0.62], Model discrimination was comparable across procedure- and demographic-specific sub-cohorts. Model calibration was excellent in all patient sub-groups.
CONCLUSIONS
The newly derived esophagectomy risk models showed similar or superior performance compared to previous models, with broader applicability and clinical face validity. These models provide robust preoperative risk estimation and can be used for shared decision-making, assessment of provider performance, and quality improvement.
