Purpose: To assess dietetic students' anxiety levels before and after a series of simulations and to document students' perceived sources of anxiety while completing simulation-based learning activities. Methods: A mixed-method convergent pilot study was conducted. Students enrolled in a Nutrition Assessment course that included a series of four simulations were invited to participate. Students completed an online pre-post simulation survey and engaged in individual interviews and a focus group discussion. The questionnaires included demographic questions and the French State-Trait Anxiety Inventory. Nonparametric tests and thematic analysis were used to examine data. Results: Fourteen students participated in the study's quantitative component and seven in the qualitative component. There was a significant decrease in trait (44.5 ± 13.8 vs 32.0 ± 14.0, P  = 0.01) and state (47.0 ± 11.2 vs 33.0 ± 18.0, P  = 0.05) anxiety from pre- to post-simulations. Individual factors influencing students' anxiety levels were stress and self-confidence. External factors influencing students' anxiety levels were unknown situations, observers, patient profiles, observers' feedback, preparation level, and academic setting. Conclusions: Our findings suggest that ensuring the educator is not present during simulations, advance preparation, and reassurance that simulations are a learning and not an evaluation activity may be effective pedagogical strategies for dietetic educators to reduce learners' anxiety and facilitate competency development.

Background: Racialised trainees in Canada and the USA continue to disproportionately experience discrimination and harassment in learning environments despite equity, diversity, and inclusion (EDI) reform efforts. Using critical approaches to understand what problems have been conceptualised and operationalised as EDI issues within postgraduate medical education (PGME) is important to inform ongoing learning environment reform in resident training., Methods: We conducted a critical narrative review of EDI literature from 2009-2022 using critical race theory (CRT) and the concept of intersectionality to analyse how issues of discrimination in PGME have been studied. Our search yielded 2244 articles that were narrowed down to 349 articles for relevance to Canadian and American PGME contexts. We attended to reflexivity and our positionality in analysing the database and identifying themes related to EDI reform., Results: Interest convergence was noted in how EDI reform was rationalised primarily by increased productivity. Problems of learner representation, gender inequities and curricular problems were conceptualised as EDI issues. The role that racism played in EDI-related problems was largely invisible, as were explicit conceptualisations of race and gender as social constructs. Overall, there was a lack of critical or intersectional approaches in the literature reviewed. Misalignment was noted where studies would frame a problem through a critical lens, but then study the problem without attention to power., Discussion: Interest convergence and epistemic injustice can account for the absence of critical approaches due to the alignment of existing EDI work with institutional interests and priorities. Interest convergence conceptually limits existing EDI reform efforts in PGME. CRT and intersectionality connect racialised learner experiences to systemic phenomena like racism and other forms of discrimination to challenge dominant assumptions. Because they attend to power, critical approaches are key to understanding why inequities have persisted to advance equity in learning environments for racialised and intersectionally marginalised learners., (© 2024 The Authors.

In Canada, lower income households and essential workers were disproportionately at risk of SARS-CoV-2. Early in the pandemic, stay-at-home restriction policies were used to limit virus transmission. There remains an evidence gap in how changes in mobility, in response to the policies, varied across socioeconomic measures in Canada. The study objective was to describe the variability in mobility change to two restrictions, by neighborhood-level income and by proportion essential workers across five regions in Ontario, Canada. The first restriction was implemented on March 17, 2020 in all five regions; and the second restriction was implemented in November 23, 2020 in two of the regions. Using cell-phone mobility data aggregated to the census tract, we compared the average mobility (% of devices that travelled outside their "primary location") three weeks before and after each restriction. We defined the adjusted mobility change via pre-restriction mobility subtracted from post-restriction, adjusted for 2019 levels. We used difference-in-differences analysis to quantify effect modification of the second restriction's effect by socioeconomic measures. With the first restriction, crude mobility fell from 77.7% to 41.6% across the five regions. The adjusted mobility change to the first restriction was largest in the highest-income neighborhoods (-43.3% versus -38.4%) and in neighborhoods with the fewest essential workers (-44.5% versus -37.6%). The overall adjusted mobility change to the second restriction was small: -0.96% (95% confidence intervals, -1.53 to -0.38%). However, there was evidence of effect modification by socioeconomic measures (less pronounced decrease in lower-income neighborhoods and more essential workers). The findings suggest a temporal saturation effect of restrictions over subsequent waves, and a saturation effect by income and occupation, leading to prevention gaps across populations by socioeconomic measures. Findings highlight the need for tailored approaches at the intersections of income and occupation when addressing epidemics of novel and resurging respiratory pathogens., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Wang et al.

Objective: The purpose of this guideline is to promote recognition and preventive strategies for obstetrical anal sphincter injuries. Furthermore, it provides guidance on primary repair and immediate postpartum management for obstetrical anal sphincter tears in order to minimize further negative sequelae., Target Population: All patients having a vaginal delivery and those who have sustained an obstetrical anal sphincter injury., Outcomes: Certain preventive strategies have been associated with lower rates of obstetrical anal sphincter injuries (e.g., fetal head flexion and control, appropriate use of mediolateral episiotomy). Management strategies, including appropriate diagnosis and repair of obstetrical anal sphincter injuries, antibiotic prophylaxis, and bowel and bladder function management can decrease associated short- and long-term complications., Benefits, Harms, and Costs: Implementation of the recommendations in this guideline may increase detection, prevention, and appropriate management of obstetrical anal injuries, thus limiting the future burden associated with these injuries. Implementation of the recommended classification of obstetrical anal sphincter injuries will improve national and international research efforts., Evidence: Published literature was retrieved through searches of PubMed, Ovid, Medline, Embase, Scopus, and the Cochrane Library from September 1, 2014, through November 30, 2023, using appropriate MeSH terms (delivery, obstetrics, obstetric surgical procedures, obstetric labor complications, anal canal, episiotomy) and keywords (OASIS, obstetrical anal sphincter injury, anal injury, anal sphincter, vaginal delivery, suture, fecal incontinence, anal incontinence, overlap repair, end-to-end repair, bladder protocol, analgesia). Results were restricted to systematic reviews, meta-analyses, randomized controlled trials/controlled clinical trials, observational studies, and clinical practice guidelines. Results were limited to English- or French-language materials. Evidence was supplemented with references from the 2015 Society of Obstetricians and Gynaecologists of Canada guideline no. 330., Validation Methods: The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and conditional recommendations)., Intended Audience: Obstetrical care providers., Tweetable Abstract: Updated Canadian guideline on recognition, prevention and management of obstetrical anal sphincter injuries (OASIS)., Summary Statements: RECOMMENDATIONS., (Copyright © 2024.

Introduction: Despite the recognized importance of interprofessional collaboration (IPC) in trauma care, healthcare professionals often work in silos. Interprofessional (IP) interventions are crucial for optimizing IPC and delivering high-quality care across clinical contexts, yet their effectiveness throughout the inpatient trauma care continuum is not well understood. Thus, this review aimed to examine the literature on the effectiveness of IP interventions on collaboration processes and related outcomes in inpatient trauma care., Methods: We conducted a scoping review following Joanna Briggs Institute's methodology. We searched six databases for studies from the last decade on IP interventions in inpatient trauma care. Two independent reviewers categorized IP interventions (education, practice, organization) and extracted their impact on IPC processes and related outcomes (team performance, patient, organization)., Results: Of the 17,397 studies screened, 148 met the inclusion criteria. Most were cohort designs (72%), conducted in level I trauma centers (57%) and emergency departments (51%), and involved surgeons (56%) and nurses (53%). Studies focused on IP organization interventions (51%), such as clinical pathways; IP practice interventions (35%), such as trauma team activation protocols; and IP education interventions (14%) including multi-method education. IP practice interventions most effectively improved team performance results, while IP education interventions primarily improved IPC processes. Positive patient outcomes were limited, with few studies examining organizational effects., Conclusions: Significant advancements are still required in IP interventions and trauma care research. Future studies should rigorously explore the effectiveness of interventions throughout the inpatient trauma care continuum and focus on developing robust measures for patient and organizational outcomes., Competing Interests: Declaration of competing interest The authors declare that they have no conflicts of interest., (Copyright © 2024 The Author(s).

Purpose: To develop an in-depth understanding of spinal cord injury (SCI) researchers' barriers and facilitators to deciding to use 1) a partnered approach to research and, 2) systematically developed principles for guiding Integrated Knowledge Translation (IKT) in spinal cord injury research (IKT Guiding Principles)., Methods: Qualitative interview study with North American SCI researchers who were interested in using a partnered research approach. The research was conducted using an IKT approach, and interview data were analyzed using reflexive thematic analysis., Results: Thirteen SCI researchers whose research focused on prevention, clinical, rehabilitation, and/or community SCI research were interviewed. Three themes were co-constructed with partners: 1) the principles are necessary but not sufficient for the implementation of a partnered approach to research; 2) relational capacity building is needed; and 3) institutional transformation is needed to value, resource, and support meaningful engagement., Conclusions: Supporting change that enables SCI researchers to adopt and implement the IKT Guiding Principles will require transformation at the individual ( theme 1 ), relational ( theme 2 ), and institutional levels ( theme 3 ). Findings provide clear, practical, and tangible actions to promote change that can support meaningful engagement in the SCI Research System.

Introduction: The International Association for the Study of Lung Cancer developed a global multicenter database to propose evidence-based revisions for the ninth edition of the TNM classification of pleural mesothelioma (PM). This study analyzes the M category to validate eighth edition M category recommendations., Methods: Cases were submitted electronically or by transfer of existing institutional databases for patients with histologically or cytologically confirmed PM. The presence and number of metastases (single versus multiple) in each of eight organ systems were reported for patients with M1 disease at diagnosis. Overall survival (OS) was calculated by the Kaplan-Meier method. Differences in OS were assessed by log-rank test., Results: Of 7338 submitted cases, 3598 were eligible and 3221 had sufficient data for clinical staging; 228 cases (7%) were M1. Median overall estimated survival was inferior for M1 compared with M0 patients: 10.5 months versus 21.5 months, respectively (p < 0.0001); estimated 1-year survival was 46% versus 71%, respectively. OS differences between M categories were preserved within histologic subgroups. Among 158 patients with organ-specific documentation of M1 disease, there was no statistically significant difference in OS between those with intrathoracic versus more distant metastatic disease (14.4 mo versus 10.9 mo, p = 0.64). No significant survival difference was detected between patients with metastatic disease in a single-organ system versus multiple-organ systems (12.6 mo versus 8.8 mo, p = 0.45)., Conclusions: This evidence-based analysis of the M category for PM conforms with the eighth edition M descriptors. No changes are proposed in the ninth edition of the mesothelioma M category., Competing Interests: Disclosure Dr. Kindler’s work is supported in part by the University of Chicago Cancer Center Support Grant P30 CA014599.

Background: Understanding the frequency of violence experienced by female sex workers (FSWs) and how violence contributes to HIV transmission can help improve HIV programs., Methods: Using recent recommendations for modelling structural factors and associated causal pathways, we developed a HIV transmission dynamic model for FSWs and their clients in Mombasa, Kenya, mechanistically representing three types of violence (sexual violence, SV; physical violence, PV; police assault and arrest, PAA). Each type of violence affects HIV transmission through key mediators (condom non-use, HIV testing). We parameterized the model using data from a cross-sectional study of FSWs aged 15-24 recruited from a systematic geographical mapping sampling frame in Mombasa, Kenya (Cheuk E et al., Frontiers in Reproductive Health 2(7), 2020). Using this model, calibrated (and cross-validated) to HIV epidemiological and violence outcomes, we estimated the incidence of violence episodes, the contribution of violence to the HIV epidemic measured by the transmission population-attributable fraction, and the potential impact of possible violence interventions., Results: The median estimated incidence of PAA in 2023 among FSWs who had not previously experienced that type of violence was 0.20 (95% credible interval: 0.17-0.22) per person-year (ppy), about double the incidence of SV and PV (0.10 (0.09-0.11), 0.11 (0.09-0.12), respectively). The incidence of violence was higher among FSWs who had previously experienced violence: the incidence of recurrent PV was 2.65 (1.82-3.37) ppy, while the incidence of recurrent SV and PAA were 1.26 (0.80-1.67) and 1.37 (0.94-1.74 ppy, respectively. In this setting, we estimated that a median of 35.3% (3.4-55.8%) infections in FSWs and clients combined over the next 10 years may be due to all types of violence (and mediators), mainly through reduced condom use in FSWs who have ever experienced SV (34.6% (2.4-55.5%)). Interventions that prevent future violence without mitigating the effects of past violence may only prevent 8.8% (0.8-14.0%) infections over 10 years., Conclusions: FSWs in Mombasa experience violence frequently. In this population, we find that addressing sexual violence, including mitigating the effects of past violence, is potentially important in reducing HIV transmission in this population. However, the wide uncertainty range shows longitudinal studies are needed to strengthen the evidence of the influence of violence on HIV risk behavior. We find that the recommendations for modelling structural factors provide a useful framework for describing the model., (© 2024. The Author(s).)

Introduction: The Gram-positive actinobacterium Streptomyces scabies is the major causal agent of potato common scab. The main pathogenicity factor is thaxtomin A, a phytotoxin that causes atypical cell death, although other secondary metabolites have been described to play a role in S. scabies virulence. Despite this, many aspects of the interaction between S. scabies and its primary host Solanum tuberosum L. remain to be elucidated., Methods: Intracellular proteins of S. scabies EF-35 grown in the presence of in vitro produced tubers (microtubers) of the Russet Burbank and Yukon Gold potato cultivars were extracted and analysed by electrospray mass spectrometry (ES MS/MS). Based on the results of proteomic analysis, iron quantification by ICP-MS and nitrite quantification using Griess reagent in growth media as well as RT-qPCR analysis of the siderophore pyochelin gene expression were performed in the presence and absence of microtubers. Hydrogen peroxide accumulation was also determined in the nutrient medium used for co-cultivation of bacteria and potato microtubers., Results: Potato microtubers caused an increase in the content of bacterial proteins involved in stress and defense, secondary metabolism, and cell differentiation, as well as secreted proteins. Co-cultivation with potato microtubers induced the accumulation of S. scabies proteins implicated in siderophore pyochelin biosynthesis, nitrite production and oxidative stress perception and response. The increase in the abundance of proteins related to pyochelin biosynthesis was consistent with a significant decrease in the iron content in the culture medium, as well as with induction of expression of pyochelin biosynthesis genes. Elevated nitrite/sulfite reductase protein levels were associated with increased nitrite excretion by S. scabies cells in the presence of host microtubers. The increase in the levels of proteins associated with signaling and oxidative stress response could have been caused by the accumulation of ROS, in particular hydrogen peroxide, detected in the studied system., Discussion: These findings show that interactions of S. scabies with living potato microtubers induce the production of secondary metabolites, defense responses, and protection from oxidative stress. This study suggests the importance of iron during host - S. scabies interactions, resulting in competition between pathogen and its host., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Giroux, Isayenka, Lerat, Beaudoin and Beaulieu.)

Importance: Reducing low-value care has the potential to improve patient experiences and outcomes and decrease the unnecessary use of health care resources. Research suggests that low-value practices (ie, the potential for harm exceeds the potential for benefit) in adult trauma care are frequent and subject to interhospital variation; evidence on low-value practices in pediatric trauma care is lacking., Objective: To estimate the incidence of low-value practices in pediatric trauma care and evaluate interhospital practice variation., Design, Setting, and Participants: A retrospective multicenter cohort study in a Canadian provincial trauma system was conducted. Children younger than 16 years admitted to any of the 59 provincial trauma centers from April 1, 2016, to March 31, 2022, were included., Main Outcomes and Measures: Low-value practices were identified from systematic reviews of clinical practice guidelines on pediatric trauma. The frequencies of low-value practices were evaluated by estimating incidence proportions and cases per 1000 admissions (low if ≤10% and ≤10 cases, moderate if >10% or >10 cases, and high if >10% and >10 cases) were identified. Interhospital variation with intraclass correlation coefficients (ICCs) were assessed (low if <5%, moderate if 5%-20%, and high if >20%)., Results: A total of 10 711 children were included (mean [SD] age, 7.4 [4.9] years; 6645 [62%] boys). Nineteen low-value practices on imaging, fluid resuscitation, hospital/intensive care unit admission, specialist consultation, deep vein thrombosis prophylaxis, and surgical management of solid organ injuries were identified. Of these, 14 (74%) could be evaluated using trauma registry data. Five practices had moderate to high frequencies and interhospital variation: head computed tomography in low-risk children (7.1%; 33 per 1000 admissions; ICC, 8.6%), pretransfer computed tomography in children with a clear indication for transfer (67.6%; 4 per 1000 admissions; ICC, 5.7%), neurosurgical consultation in children without clinically important intracranial lesions (11.6%; 13 per 1000 admissions; ICC, 15.8%), hospital admission in isolated mild traumatic brain injury (38.8%; 98 per 1000 admissions; ICC, 12.4%), and hospital admission in isolated minor blunt abdominal trauma (10%; 5 per 1000 admissions; ICC, 31%)., Conclusions and Relevance: In this cohort study, low-value practices appeared to be frequent and subject to interhospital variation. These practices may represent priority targets for deimplementation interventions, particularly as they can be measured using routinely collected data.

This analysis aimed to (1) identify longitudinal joint trajectories of participation in organized and unorganized physical activity contexts, and level of daily moderate-to-vigorous physical activity (MVPA) and (2) assess whether basic psychological need satisfaction during adolescence differentiates between membership in different physical activity trajectories. Participants (n = 888; 56% girls) reported their involvement in 36 different physical activities, level of MVPA, and their perceived satisfaction of competence, autonomy, and relatedness satisfaction in physical activity up to three times per year, over 8 years (from ages 10 to 17 years). Group-based multi-trajectory models were used to identify longitudinal joint trajectories of physical activity participation. We estimated a multinomial logistic regression model for membership in a physical activity trajectory by including individual-level intercepts and slopes for each psychological need obtained using mixed models over the 24 cycles modelized as natural cubic splines. Five longitudinal trajectory groups emerged: Non-participants, Dropouts, Active in unorganized physical activities, Active in organized physical activities, and Active through a variety of activities. Relative to Non-participants, we identify a dose-response relationship in baseline competence and membership in the higher active trajectory groups. In addition, a positive change in competence in early adolescence predicted membership in all three Active trajectory groups., (© 2024 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objectives: The primary objective of this project was to develop a comprehensive COVID-19 non-pharmaceutical interventions' index for the province of Québec (QCnPI-Index). The resulting database systematically categorizes, multiple non-pharmaceutical interventions implemented in the 17 administrative regions (AR) of the province of Québec to mitigate the spread of COVID-19 in the form of an index., Data Description: Data represent interventions and groups of interventions implemented during the COVID-19 period in Québec. They are a compilation of policies, guidelines, and governmental interventions related to COVID-19, considering temporal and geographical dimensions. Data were collected for all 17 AR of Québec using dates as unit of analysis, from March 2020 to April 2022. They were first collected and then coded by an interdisciplinary research team to form the foundation of the QCnPI-Index., Contribution: This quantitative instrument offers the necessary granularity for nuanced spatial and temporal studies within the province of Québec, using AR, for instance, as unit of analysis. With this database, pre-, during-, and post-COVID periods can thus be better analyzed. Additionally, the innovative methodologies employed for data collection, coding, and weighting offer valuable insights that may have broader applications in public health, epidemiology, and other research domains. The QCnPI-Index could be instrumental for public health, epidemiology, and transportation researchers investigating the multifaceted impacts of non-pharmaceutical interventions on various societal domains, such as road safety, alcohol and cannabis consumption, and/or mental health, in the province of Québec., (© 2024.

Disordered eating refers to a range of eating behaviours and attitudes towards weight and food that can negatively influence physical and psychosocial well-being. The menopausal transition could be a vulnerable period for disordered eating due to major hormonal fluctuations, menopausal symptoms, common body composition shifts, and an increased risk of psychological challenges. This systematic review aimed to summarize evidence on the associations between the menopausal transition and disordered eating. Records published before October 2023 were identified through MEDLINE, PsycINFO, Scopus, Embase, and CINAHL. Studies investigating associations between menopausal status, menopausal symptoms, or reproductive hormone levels, and disordered eating during the menopausal transition were sought. A total of 1301 non-duplicate records were screened, with 10 studies deemed eligible for inclusion. Most included studies used a cross-sectional design ( n  = 9). Findings include potentially higher levels of binge eating during the perimenopausal stage, whereas restrictive eating behaviours appeared more common during postmenopause compared to premenopause. Both studies investigating menopausal symptoms found strong positive associations with disordered eating. Nonetheless, findings are equivocal with contrasting results and limited methodological quality across studies. Further research is needed to verify these findings and better assist health professionals in supporting healthy eating behaviours in menopausal women during this complex transition.

Objectives: To estimate the epidemiological impact of past HIV interventions and the magnitude and contribution of undiagnosed HIV among different risk groups on new HIV acquisitions in Côte d'Ivoire, Mali and Senegal., Design: HIV transmission dynamic models among the overall population and key populations [female sex workers (FSW), their clients, and MSM]., Methods: Models were independently parameterized and calibrated for each set of country-specific demographic, behavioural, and epidemiological data. We estimated the fraction of new HIV infections over 2012-2021 averted by condom use and antiretroviral therapy (ART) uptake among key populations and non-key populations, the direct and indirect contribution of specific groups to new infections [transmission population-attributable fraction (tPAF)] over 2012-2021 due to prevention gaps, and the distribution of undiagnosed people with HIV (PWH) by risk group in January 2022 and their tPAF over 2022-2031., Results: Condom use and ART may have averted 81-88% of new HIV infections over 2012-2021 across countries, mostly due to condom use by key population. The tPAF of all key populations combined over 2012-2021 varied between 27% (Côte d'Ivoire) and 79% (Senegal). Male key populations (clients of FSW and MSM) contributed most to new infections (>60% in Mali and Senegal) owing to their higher HIV prevalence and larger prevention gaps. In 2022, men represented 56% of all PWH with an undiagnosed infection in Côte d'Ivoire (male key populations = 15%), 46% in Mali (male key populations = 23%), and 69% in Senegal (male key populations = 55%). If HIV testing and ART initiation rates remain at current levels, 20% of new HIV infections could be due to undiagnosed key populations living with HIV in Côte d'Ivoire over 2022-2031, 53% in Mali, and 65% in Senegal., Conclusion: Substantial HIV diagnosis gaps remain in Western Africa, especially among male key populations. Addressing these gaps is key to impacting the HIV epidemics in the region and achieving the goal of ending AIDS by 2030., (Copyright © 2024 The Author(s). Published by Wolters Kluwer Health, Inc.)

Background: Exercise is widely considered to have beneficial impact on skeletal muscle aging. In addition, there are also several studies demonstrating a positive effect of exercise on muscular dystrophies. Oculopharyngeal muscular dystrophy (OPMD) is a late-onset autosomal dominant inherited neuromuscular disorder caused by mutations in the PAPBN1 gene. These mutations consist in short (1-8) and meiotically stable GCN trinucleotide repeat expansions in its coding region responsible for the formation of PAPBN1 intranuclear aggregates. This study aims to characterize the effects of two types of chronic exercise, resistance and endurance, on the OPMD skeletal muscle phenotype using a relevant murine model of OPMD., Methods: In this study, we tested two protocols of exercise. In the first, based on endurance exercise, FvB (wild-type) and A17 (OPMD) mice underwent a 6-week-long motorized treadmill protocol consisting in three sessions per week of running 20 cm/s for 20 min. In the second protocol, based on resistance exercise generated by chronic mechanical overload (OVL), surgical removal of gastrocnemius and soleus muscles was performed, inducing hypertrophy of the plantaris muscle. In both types of exercise, muscles of A17 and FvB mice were compared with those of respective sedentary mice. For all the groups, force measurement, muscle histology, and molecular analyses were conducted., Results: Following the endurance exercise protocol, we did not observe any major changes in the muscle physiological parameters, but an increase in the number of PABPN1 intranuclear aggregates in both tibialis anterior (+24%, **P = 0.0026) and gastrocnemius (+18%, ****P < 0.0001) as well as enhanced collagen deposition (+20%, **P = 0.0064 in the tibialis anterior; +35%, **P = 0.0042 in the gastrocnemius) in the exercised A17 OPMD mice. In the supraphysiological resistance overload protocol, we also observed an increased collagen deposition (×2, ****P < 0.0001) in the plantaris muscle of A17 OPMD mice which was associated with larger muscle mass (×2, ****P < 0.0001) and fibre cross sectional area (×2, ***P = 0.0007) and increased absolute maximal force (×2, ****P < 0.0001) as well as a reduction in PABPN1 aggregate number (-16%, ****P < 0.0001)., Conclusions: Running exercise and mechanical overload led to very different outcome in skeletal muscles of A17 mice. Both types of exercise enhanced collagen deposition but while the running protocol increased aggregates, the OVL reduced them. More importantly OVL reversed muscle atrophy and maximal force in the A17 mice. Our study performed in a relevant model gives an indication of the effect of different types of exercise on OPMD muscle which should be further evaluated in humans for future recommendations as a part of the lifestyle of individuals with OPMD., (© 2024 The Author(s).

Background: Pulmonary sarcomatoid carcinomas (PSC) are notorious for their poor prognosis and resistance to chemotherapy. The literature suggests that immunotherapy might be effective against this aggressive tumor. This study aims to evaluate the efficacy of immunotherapy, either alone or combined with chemotherapy, as first-line treatment for PSC patients., Methods: In a retrospective, multicentric, real-world study conducted between July 2017 and April 2021, patients with stage III (ineligible for surgery or radio-chemotherapy) or stage IV PSC were enrolled. These patients received their first-line treatment with immunotherapy and were categorized into two groups based on their treatment modality: the immuno-chemotherapy (IO CT) group or the immunotherapy-alone (IO) group., Results: This study analyzed a population of 34 patients from eight different hospital centers. In this cohort, the objective response rate (ORR) was 56%, median duration of response was 20.5 months, median progression-free survival (PFS) was 5.11 months, and median overall survival (OS) 13.9 months. Demographic characteristics remained consistent among the treatment groups except for the age (54.0- and 71.0-year-old in the IO CT and IO group, respectively, P=0.02). The IO CT group demonstrated an ORR of 64.0%, a median PFS at 8.72 months, and a median OS of 16.08 months, while the IO group displayed respective values of 52.0%, 3.45 months, and 13.11 months., Conclusions: This study showed the potential efficacy of immunotherapy as a first-line treatment for PSC. While acknowledging the retrospective nature of the study, our findings suggest a trend favoring the combination of IO CT over IO alone in these patients., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://tlcr.amegroups.com/article/view/10.21037/tlcr-24-263/coif).

Background: High rates of psychiatric comorbidities have been found in people with problem gambling (PBG), including substance use, anxiety, and mood disorders. Psychotic disorders have received less attention, although this comorbidity is expected to have a significant impact on the course, consequences, and treatment of PBG. This review aimed to estimate the prevalence of psychotic disorders in PBG., Methods: Medline (Ovid), EMBASE, PsycINFO (Ovid), CINAHL, CENTRAL, Web of Science, and ProQuest were searched on November 1, 2023, without language restrictions. Studies involving people with PBG and reporting the prevalence of schizophrenia spectrum and other psychotic disorders were included. Risk of bias was assessed using the Joanna Briggs Institute critical appraisal checklist for systematic reviews of prevalence data. The pooled prevalence of psychotic disorders was calculated using a random effects generalized linear mixed model and presented with forest plots., Results: Of 1,271 records screened, 22 studies ( n  = 19,131) were included. The overall prevalence of psychotic disorders was 4.9% (95% CI, 3.6-6.5%, I 2  = 88%). A lower prevalence was found in surveyed/recruited populations, compared with treatment-seeking individuals and register-based studies. No differences were found for factors such as treatment setting (inpatient/outpatient), diagnoses of psychotic disorders (schizophrenia only/other psychotic disorders), and assessment time frame (current/lifetime). The majority of included studies had a moderate risk of bias., Conclusions: These findings highlight the relevance of screening problem gamblers for schizophrenia spectrum and other psychotic disorders, as well as any other comorbid mental health conditions, given the significant impact such comorbidities can have on the recovery process.

Background: Including structural determinants (e.g. criminalisation, stigma, inequitable gender norms) in dynamic HIV transmission models is important to help quantify their population-level impacts and guide implementation of effective interventions that reduce the burden of HIV and inequalities thereof. However, evidence-based modelling of structural determinants is challenging partly due to a limited understanding of their causal pathways and few empirical estimates of their effects on HIV acquisition and transmission., Methods: We conducted a scoping review of dynamic HIV transmission modelling studies that evaluated the impacts of structural determinants, published up to August 28, 2023, using Ovid Embase and Medline online databases. We appraised studies on how models represented exposure to structural determinants and causal pathways. Building on this, we developed a new methodological framework and recommendations to support the incorporation of structural determinants in transmission dynamics models and their analyses. We discuss the data and analyses that could strengthen the evidence used to inform these models., Results: We identified 17 HIV modelling studies that represented structural determinants and/or interventions, including incarceration of people who inject drugs (number of studies [n] = 5), violence against women (n = 3), HIV stigma (n = 1), and housing instability (n = 1), among others (n = 7). Most studies (n = 10) modelled exposures dynamically. Almost half (8/17 studies) represented multiple exposure histories (e.g. current, recent, non-recent exposure). Structural determinants were often assumed to influence HIV indirectly by influencing mediators such as contact patterns, condom use, and antiretroviral therapy use. However, causal pathways' assumptions were sometimes simple, with few mediators explicitly represented in the model, and largely based on cross-sectional associations. Although most studies calibrated models using HIV epidemiological data, less than half (7/17) also fitted or cross-validated to data on the prevalence, frequency, or effects of exposure to structural determinants., Conclusions: Mathematical models can play a crucial role in elucidating the population-level impacts of structural determinants and interventions on HIV. We recommend the next generation of models reflect exposure to structural determinants dynamically and mechanistically, and reproduce the key causal pathways, based on longitudinal evidence of links between structural determinants, mediators, and HIV. This would improve the validity and usefulness of predictions of the impacts of structural determinants and interventions., (© 2024. The Author(s).)

The objective of this study was to understand gynecological cancer (GC) survivors' and their informal caregivers' perceptions about the usability of an educational resource to support their transition from primary cancer treatment into surveillance and/or recovery. After developing an empirical- and experiential-informed educational resource, we used a semi-structured questioning process to understand GC survivors and their caregivers' perceptions about its usability. Data were collected via online focus groups or 1:1 interviews that were audio recorded and transcribed. We used thematic analysis to analyze the data. Ten participants who were survivors or informal caregivers of cervical, ovarian, or uterine/endometrial cancer participated in two rounds of data collection. We grouped qualitative data into two themes: (1) reputable, relevant, and accessible education reduces uncertainty and promotes connection, and (2) individualized delivery of education provided by trusted cancer clinicians. The transition from treatment to surveillance is a challenging time for which reputable, relevant, and accessible educational resources are useful to facilitate an understanding about and self-management of survivorship-related concerns. Survivors and caregivers look to clinicians to provide reputable education to address their needs. This education should be diverse in content and referred to repeatedly throughout the cancer trajectory., (© 2024.

Introduction: The International Association for the Study of Lung Cancer developed an international database to inform potential revisions in the ninth edition of the TNM classification of diffuse pleural mesothelioma (PM). This study analyzed the clinical and pathologic N categories to determine whether revisions were indicated relative to the eighth edition staging system., Methods: Of 7338 PM cases diagnosed from 2013 to 2022 and 3598 met all inclusion criteria for planned analyses. Data on 2836 patients without metastases were included in this study. Overall survival (OS) was measured from date of diagnosis. Patients were included regardless of whether they received neoadjuvant treatment. For the pathologic N analysis, patients who underwent resection (extrapleural pneumonectomy or pleurectomy/decortication) were included. N subgroups were analyzed and OS assessed by the Kaplan-Meier method., Results: The existing eighth edition N categories were performed adequately in the ninth edition data set. A median OS advantage was noted for clinical and pathologic N0 versus N1 patients: 23.2 versus 18.5 and 33.8 versus 25.0 months, respectively. Patients with resected pN0 had a 3-year OS of 48%. No difference in OS was noted for single- versus multiple-station nodal metastases. The number of nodal stations sampled at the time of resection was not associated with a difference in OS., Conclusions: Data regarding clinical and pathologic N categories corroborate those used in the eighth edition. No changes in the N categories are recommended in the ninth edition of PM staging system., Competing Interests: Disclosure Dr. Pass reports serving on the steering committee and speakers bureau of Roche and serving on the advisory board of AstraZeneca.

Background: Thoracic radiation intensification is debated in patients with stage III non-small-cell lung cancer (NSCLC). We aimed to assess the activity and safety of a boost radiotherapy dose up to 74 Gy in a functional sub-volume given according to on-treatment [ 18 F]fluorodeoxyglucose ([ 18 F]FDG)-PET results., Methods: In this multicentre, randomised, controlled non-comparative phase 2 trial, we recruited patients aged 18 years or older with inoperable stage III NSCLC without EGFR mutation or ALK rearrangement with an Eastern Cooperative Oncology Group performance status of 0-1, and who were affiliated with or a beneficiary of a social benefit system, with evaluable tumour or node lesions, preserved lung function, and who were amenable to curative-intent radiochemotherapy. Patients were randomly allocated using a central interactive web-response system in a non-masked method (1:1; minimisation method used [random factor of 0·8]; stratified by radiotherapy technique [intensity-modulated radiotherapy vs three-dimensional conformal radiotherapy] and by centre at which patients were treated) either to the experimental adaptive radiotherapy group A, in which only patients with positive residual metabolism on [ 18 F]FDG-PET at 42 Gy received a boost radiotherapy (up to 74 Gy in 33 fractions), with all other patients receiving standard radiotherapy dosing (66 Gy in 33 fractions over 6·5 weeks), or to the standard radiotherapy group B (66 Gy in 33 fractions) over 6·5 weeks. All patients received two cycles of induction platinum-based chemotherapy cycles (paclitaxel 175 mg/m 2 intravenously once every 3 weeks and carboplatin area under the curve [AUC]=6 once every 3 weeks, or cisplatin 80 mg/m 2 intravenously once every 3 weeks and vinorelbine 30 mg/m 2 intravenously on day 1 and 60 mg/m 2 orally [or 30 mg/m 2 intravenously] on day 8 once every 3 weeks). Then they concomitantly received radiochemotherapy with platinum-based chemotherapy (three cycles for 8 weeks, with once per week paclitaxel 40 mg/m 2 intravenously and carboplatin AUC=2 or cisplatin 80 mg/m 2 intravenously and vinorelbine 20 mg/m 2 intravenously on day 1 and 40 mg/m 2 orally (or 20 mg/m 2 intravenously) on day 8 in 21-day cycles). The primary endpoint was the 15-month local control rate in the eligible patients who received at least one dose of concomitant radiochemotherapy. This RTEP7-IFCT-1402 trial is registered with ClinicalTrials.gov (NCT02473133), and is ongoing., Findings: From Nov 12, 2015, to July 7, 2021, we randomly assigned 158 patients (47 [30%] women and 111 [70%] men) to either the boosted radiotherapy group A (81 [51%]) or to the standard radiotherapy group B (77 [49%)]. In group A, 80 (99%) patients received induction chemotherapy and 68 (84%) received radiochemotherapy, of whom 48 (71%) with residual uptake on [ 18 F]FDG-PET after 42 Gy received a radiotherapy boost. In group B, all 77 patients received induction chemotherapy and 73 (95%) received radiochemotherapy. At the final analysis, the median follow-up for eligible patients who received radiochemotherapy (n=140) was 45·1 months (95% CI 39·3-48·3). The 15-month local control rate was 77·6% (95% CI 67·6-87·6%) in group A and 71·2% (95% CI 60·8-81·6%) in group B. Acute (within 90 days from radiochemotherapy initiation) grade 3-4 adverse events were observed in 20 (29%) of 68 patients in group A and 33 (45%) of 73 patients in group B, including serious adverse events in five (7%) patients in group A and ten (14%) patients in group B. The most common grade 3-4 adverse events were febrile neutropenia (seven [10%] of 68 in group A vs 16 [22%] of 73 in group B), and anaemia (five [7%] vs nine [12%]). In the acute phase, two deaths (3%) occurred in group B (one due to a septic shock related to chemotherapy, and the other due to haemotypsia not related to study treatment), and no deaths occurred in group A. After 90 days, one additional treatment-unrelated death occurred in group A and two deaths events occurred in group B (one radiation pneumonitis and one pneumonia unrelated to treatment)., Interpretation: A thoracic radiotherapy boost, based on interim [ 18 F]FDG-PET, led to a meaningful local control rate with no difference in adverse events between the two groups in organs at risk, in contrast with previous attempts at thoracic radiation intensification, warranting a randomised phase 3 evaluation of such [ 18 F]FDG-PET-guided radiotherapy dose adaptation in patients with stage III NSCLC., Funding: Programme Hospitalier de Recherche Clinique National 2014., Competing Interests: Declaration of interests EM declared payment or honoraria for lectures, presentations, speakers bureaus, manuscript writing, or educational events from Varian Medical Systems, AstraZeneca, MSD, Janssen, and Sanofi; support for attending meetings or travel, or both, from Ipsen, Janssen, and AstraZeneca; and participation on a data safety monitoring board or advisory board for AstraZeneca and Janssen.

Introduction: The eighth edition of the TNM classification of pleural mesothelioma (PM) saw substantial changes in T and N components and stage groupings. The International Association for the Study of Lung Cancer collected data into a multinational database to further refine this classification. This ninth edition proposal incorporates changes proposed in the clinical (c)T component but not the pathologic T component, to include size criteria, and further refines TNM stage groupings for PM., Methods: Data were submitted through electronic data capture or batch transfer from institutional databases. Survival was measured from diagnosis date. Candidate stage groups were developed using a recursive partitioning and amalgamation algorithm applied to all cM0 cases for clinical stage and subsequently for pathologic stage. Cox models were developed to estimate survival for each stage group., Results: Of 3598 submitted cases, 2192 were analyzable for overall clinical stage and 445 for overall pathologic stage. Recursive partitioning and amalgamation generated survival tree on overall survival outcomes restricted to cM0, with newly proposed (ninth edition) cT and cN component-derived optimal stage groupings of stage I (T1N0), II (T1N1; T2N0), IIIA (T1N2; T2N1/2; any T3), IIIB (any T4), and IV (any M1). Although cT and pathologic T descriptors are different in the ninth edition, aligning pathologic stage groupings with clinical stage produced better discrimination than did retaining eighth edition pathologic stage groupings., Conclusions: To our knowledge, this revision of the clinical TNM classification for PM is the first to incorporate the measurement-based proposed changes in cT category. The pathologic TNM aligns with clinical TNM., Competing Interests: Disclosure Dr. Ripley receives institutional clinical trial funding from AstraZeneca and Merck Speakers’ Bureau.

In paediatrics, the pulmonary function test (PFT) is most often performed to support the diagnosis or in follow-up of asthma patients. Whatever the pathology responsible for respiratory symptoms and/or functional impairment, repeated PFTs make it possible to establish a prognosis (pulmonary function trajectories…) and to orient preventive interventions. PFT can be performed routinely from the age of three years, provided that the following requirements are met: suitable techniques and equipment, staff trained to apply the techniques and to receive young children, reference values for each technique indicating the limits of normal values and of between-test significant variation. From the age of three, children can be subjected to tidal breathing measurement of: resistance of the respiratory system (oscillometry, Rrs; airflow interruption, Rint) or of airways specific resistance (sRaw) and functional residual capacity (by applying a dilution technique). With maturity, the child will become capable of mobilizing his or her slow vital capacity to measure total lung capacity (TLC), once again by applying a dilution technique, then later by breathing against a closed shutter (plethysmography TLC and Raw). Finally, the child will be able to carry out forced expiration (forced spirometry) along with all of the other PFTs. It is important to take into account the paediatric adaptations specified in the international recommendations regarding the performance, reproducibility and quality of PFTs targeting this population., (Copyright © 2024 SPLF.

Staging and stratification are two diagnostic approaches that have introduced a more dynamic outlook on the development of diseases, thus participating in blurring the line between the normal and the pathological. First, diagnostic staging, aiming to capture how diseases evolve in time and/or space through identifiable and gradually more severe stages, may be said to lean on an underlying assumption of "temporal determinism". Stratification, on the other hand, allows for the identification of various prognostic or predictive subgroups based on specific markers, relying on a more "mechanistic" or "statistical" form of determinism. There are two medical fields in which these developments have played a significant role and have given rise to sometimes profound nosological transformations: oncology and psychiatry. Drawing on examples from these two fields, this paper aims to provide much needed conceptual clarifications on both staging and stratification in order to outline how several epistemological and ethical issues may, in turn, arise. We argue that diagnostic staging ought to be detached from the assumption of temporal determinism, though it should still play an essential role in adapting interventions to stage. In doing so, it would help counterbalance stratification's own epistemological and ethical shortcomings. In this sense, the reflections and propositions developed in psychiatry can offer invaluable insights regarding how adopting a more transdiagnostic and cross-cutting perspective on temporality and disease dynamics may help combine both staging and stratification in clinical practice., (© 2024.

Introduction: The primary tumor (T) component in the eighth edition of pleural mesothelioma (PM) staging system is based on pleural involvement and extent of invasion. Quantitative assessment of pleural tumor has been found to be prognostic. We explored quantitative and qualitative metrics to develop recommendations for T descriptors in the upcoming ninth edition of the PM staging system., Methods: The International Association for the Study of Lung Cancer prospectively collected data on patients with PM. Sum of maximum pleural thickness (Psum) was recorded. Optimal combinations of Psum and eighth edition cT descriptors were assessed using recursive binary splitting algorithm, with bootstrap resampling to correct for the adaptive nature of the splitting algorithm, and validated in the eighth edition data. Overall survival (OS) was calculated by the Kaplan-Meier method and differences in OS assessed by the log-rank test., Results: Of 7338 patients submitted, 3598 were eligible for cT analysis and 1790 had Psum measurements. Recursive partitioning identified optimal cutpoints of Psum at 12 and 30 mm, which, in combination with extent of invasion, yielded four prognostic groups for OS. Fmax greater than 5 mm indicated poor prognosis. cT4 category (based on invasion) revealed similar performance to eighth edition. Three eighth edition descriptors were eliminated based on low predictive accuracy. Eighth edition pT descriptors remained valid in ninth edition analyses., Conclusion: Given reproducible prognostication by Psum, size criteria will be incorporated into cT1 to T3 categories in the ninth edition. Current cT4 category and all pT descriptors will be maintained, with reclassification of fissural invasion as pT2., Competing Interests: Disclosure Dr. Rusch receives institutional clinical trial funding from Genentech; meeting prep and travel reimbursement from National Institutes of Health/National Cancer Institute Thoracic Malignancy Steering Committee; unpaid member, DSMC Committee, MARS II trial (Cancer Research UK).

Background: Key population HIV programmes in sub-Saharan Africa require epidemiological information to ensure equitable and universal access to effective services. We aimed to consolidate and harmonise survey data among female sex workers, men who have sex with men, people who inject drugs, and transgender people to estimate key population size, HIV prevalence, and antiretroviral therapy (ART) coverage for countries in mainland sub-Saharan Africa., Methods: Key population size estimates, HIV prevalence, and ART coverage data from 39 sub-Saharan Africa countries between 2010 and 2023 were collated from existing databases and verified against source documents. We used Bayesian mixed-effects spatial regression to model urban key population size estimates as a proportion of the gender-matched, year-matched, and area-matched population aged 15-49 years. We modelled subnational key population HIV prevalence and ART coverage with age-matched, gender-matched, year-matched, and province-matched total population estimates as predictors., Findings: We extracted 2065 key population size data points, 1183 HIV prevalence data points, and 259 ART coverage data points. Across national urban populations, a median of 1·65% (IQR 1·35-1·91) of adult cisgender women were female sex workers, 0·89% (0·77-0·95) were men who have sex with men, 0·32% (0·31-0·34) were men who injected drugs, and 0·10% (0·06-0·12) were women who were transgender. HIV prevalence among key populations was, on average, four to six times higher than matched total population prevalence, and ART coverage was correlated with, but lower than, the total population ART coverage with wide heterogeneity in relative ART coverage across studies. Across sub-Saharan Africa, key populations were estimated as comprising 1·2% (95% credible interval 0·9-1·6) of the total population aged 15-49 years but 6·1% (4·5-8·2) of people living with HIV., Interpretation: Key populations in sub-Saharan Africa experience higher HIV prevalence and lower ART coverage, underscoring the need for focused prevention and treatment services. In 2024, limited data availability and heterogeneity constrain precise estimates for programming and monitoring trends. Strengthening key population surveys and routine data within national HIV strategic information systems would support more precise estimates., Funding: UNAIDS, Bill & Melinda Gates Foundation, and US National Institutes of Health., Competing Interests: Declaration of interests SB has received funding from the US National Institutes of Health (NIH).

Background: Intimate partner violence is a serious public health problem and negatively affects short-term and long-term health, development, and wellbeing of adolescent girls. Global estimates from WHO have shown that adolescent girls aged 15-19 years experience high rates of intimate partner violence. We aimed to estimate the lifetime and past-year prevalence and patterns of physical or sexual intimate partner violence against adolescent girls by male partners across 161 countries and areas, and to examine the country-level factors, including the prevalence of child marriage, associated with the lifetime and past-year prevalence of intimate partner violence in this age group., Methods: These analyses used the 2018 global, regional, and country estimates on intimate partner violence published by WHO and economic, social, and political metadata from subject-specific databases. Drawing on data from the WHO Global Database on Prevalence of Violence Against Women, we used hierarchical Bayesian modelling techniques to estimate lifetime and past-year prevalence of physical or sexual (or both) intimate partner violence against adolescent girls aged 15-19 years by country. Linear regression methods were used to examine contextual social, economic, and political factors associated with intimate partner violence against adolescent girls in the 101 countries (lifetime prevalence) and 105 countries (past-year prevalence) for which these metadata were available., Findings: The estimated global prevalence of physical or sexual intimate partner violence against ever-partnered adolescent girls aged 15-19 years was 24% (95% uncertainty interval 21-28) in their lifetime and 16% (14-19) in the past year. Prevalence varied greatly across countries and regions, with lifetime prevalence ranging from 6% (3-11) in Georgia to 49% (35-64) in Papua New Guinea. Overall, the prevalence of both lifetime (154 countries) and past-year (157 countries) intimate partner violence against adolescent girls was higher in low-income and lower-middle-income countries and regions than in high-income countries and regions. Countries with higher rates of female secondary school enrolment and those with inheritance laws that are more gender-equal had lower prevalence of intimate partner violence against adolescent girls. Lower-income countries and societies with a high prevalence of child marriage had higher prevalence of physical or sexual intimate partner violence against adolescent girls., Interpretation: Our findings highlight the widespread prevalence of intimate partner violence against adolescent girls across the globe and its relationship with country-level contextual factors. They emphasise the need for promoting and ensuring policies and programmes that increase and ensure gender equality. Countries should strive to provide secondary education for all girls, ensure equal property rights for women, eliminate discriminatory gender norms, and address harmful practices such as child marriage., Funding: UN Women-WHO Joint Programme on Strengthening Violence Against Women Data funded by the UK Foreign and Commonwealth Development Office and the UNDP-UNFPA-UNICEF-WHO-World Bank Special Programme of Research, Development, and Research Training in Human Reproduction., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2024 World Health Organization.

Background and Objectives: Because myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is a recently identified autoimmune disorder, the natural history of MOGAD is still not well described. The objective of this study was to describe the long-term outcomes of adult patients with MOGAD. In addition, we aimed to identify factors affecting relapse risk and neurologic outcomes., Methods: Clinical and biological data were obtained from patients with a first event of MOGAD and included in the French nationwide incident cohort between February 2014 and March 2017. Only patients aged 18 years or older at disease onset and with observation period of at least 3 months were included. Data were collected prospectively until July 2023 and registered in the dedicated French nationwide database. This form includes every relapse with phenotype description during follow-up, date of last assessment, final clinical outcome with Expanded Disability Status Scale score and visual acuity, and maintenance therapy. The probability of recurrence-free survival was assessed using the Kaplan-Meier method., Results: We included 128 patients. The onset phenotype was isolated optic neuritis in 81 patients (63.3%) and isolated myelitis in 25 patients (19.5%). The median follow-up duration was 77.8 months (range 3.2-111.2), with 49 patients (38.3%) experienced at least one relapse. Median times from onset to second and third attacks were 3.2 (1.0-86.2) and 13.0 (2.6-64.4) months, respectively. At the last assessment, Expanded Disability Status Scale Score was ≥3 and ≥6 in 22 (17.2%) and 6 (4.7%) patients, respectively. Eighty patients received at least one maintenance treatment. This treatment was initiated after the first attack in 47 patients (36.7% of the whole cohort) and at the time of a second attack in 25 (19.5%). Multivariate analysis revealed that initiating maintenance treatment after the first attack was associated with a lower relapse risk (OR = 0.26 [95% CI 0.11-0.62], p = 0.002). In patients receiving maintenance therapy after first attack, the 2-year, 4-year, 6-year, and 8-year relapse risks were 11%, 15%, 20%, and 20%, respectively. In other patients, the risks were 41%, 46%, 51%, and 56%., Discussion: The highest risk of a relapse in MOGAD occurs early, and initiating maintenance therapy from the first attack substantially reduced the relapse risk., Classification of Evidence: This study provides Class III evidence that initiating maintenance therapy from the first attack in patients with MOGAD reduces the relapse risk.

Background & Need for Innovation: Patients can be actively involved in various aspects of health professions education (HPE). However, learners in HPE graduate programs have minimal opportunities to learn how to involve patients in HPE., Steps Taken for Development and Implementation of Innovation: We designed, implemented, and evaluated a 12-week asynchronous, online graduate course that provides learners such opportunities. We established an advisory committee of patients, clinician-educators, and professors to guide course development. Using Thomas et al.'s framework, we established the general and targeted need for the course, identified the learning outcomes, determined the learning activities, and implemented and evaluated the course. It is offered within the asynchronous, online Diploma and Master in HPE at the University of Ottawa, Canada., Evaluation of Innovation: Forty learners participated in the course between 2020 and 2022. Using a survey with closed- and open-ended items, learners reported satisfaction with all course components, and they valued the patient narrative videos created for the course. After course completion, learners reported that the course is relevant to their professional practice. They also reported confidence in their abilities to actively involve patients in HPE. Based on the culminating assignment assessment data, learners attained course expectations., Critical Reflection: Although patients who participated in the narrative videos represented diverse age ranges, health conditions, and experiences in HPE, they were often Caucasian, educated, and from a higher socio-economic background. Also, the level of engagement between patients and learners in the course was limited. We are committed to improving our own patient involvement efforts., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2024 The Author(s).)

Metastatic non-small-cell lung cancer (NSCLC) displays various molecular alterations in the RAS-MAPK pathway. In particular, NSCLCs show high rates of targetable gene fusion in ALK, RET, ROS1, NRG1 and NTRK, or MET exon 14 skipping. Rapid and accurate detection of gene fusion in EGFR/KRAS/BRAF mutations is important for treatment selection especially for first-line indications. RNA-based next-generation sequencing (NGS) panels appear to be the most appropriate as all targets are multiplexed in a single run. While comprehensive NGS panels remain costly for daily practice, optimal sequencing strategies using targeted DNA/RNA panel approaches need to be validated. Here, we describe our lung cancer screening strategy using DNA and RNA targeted approaches in a real-life cohort of 589 NSCLC patients assessed for molecular testing. Gene fusions were analysed in 174 patients negative for oncogene driver mutations or ALK immunohistochemistry in a two-step strategy. Targetable alterations were identified in 28% of contributive samples. Non-smokers had a 63.7% probability to have a targetable alteration as compared to 21.5% for smokers. Overall survival was significantly higher (p=0.03) for patients who received a molecularly matched therapy. Our study shows the feasibility in routine testing of NSCLC DNA/RNA molecular screening for all samples in a cost- and time-controlled manner. The significant high fusion detection rate in patients with wild-type RAS-MAPK tumours highlights the importance of amending testing strategies in NSCLC., (Copyright © 2024.

Introduction: Chemotherapy combined with immunotherapy (CT-IO) is the standard treatment for patients with Extensive-Stage Small Cell Lung Cancer (ES-SCLC). This study evaluates the effectiveness of second-line (2L) following CT-IO., Patients and Methods: All patients from 10 centers who received a 2L after a first-line CT-IO were included. They were divided into 3 groups: platinum-based, lurbinectedin or others (topotecan, CAV, taxanes). We assessed overall survival (OS) and 2L progression-free survival (2L-PFS) according to treatment and platinum free-interval (PFI) < or ≥ 90 days., Results: Among 82 patients included, median age was 67.0 years, 29.3 % had a Performans Status ≥ 2, 36.6 % had brain progression, 69.5 % were considered "platine-sensitive" and 30.5 % "platine-resistant" (PFI ≥ or < 90 days, respectively). As 2L, 37/82 patients (45.1 %) received platinum-doublet, 21/82 (25.6 %) lurbinectedin and 24/82 (29.3 %) others. Patients with a PFI ≥ 90 days received mainly platinum-based rechallenge (34/57, 59.6 %). With a median follow-up of 18.5 months, the median OS was 5.0 months (95 %CI, 1.5-7.9) / 6.8 months (95 %CI, 5.5-8.7) for platinum-resistant / sensitive, respectively (log rank p = 0.017). The median 2L-PFS was 1.9 months (95 %CI, 1.2-4.7) / 3.9 months (95 %CI, 2.9-6.0) for platinum-resistant / sensitive, respectively. Median OS was 8.1 (95 %CI, 6.3-12.9) / 4.9 (95 %CI, 3.7-6.8) / 5.1 months (95 %CI, 2.5-7.8) with platinum rechallenge / lurbinectedin / others, respectively (p = 0.017). Median 2L-PFS was 4.6 (95 %CI, 3.9-7.2) / 2.7 (95 %CI, 1.6-3.9) / 2.2 months (95 %CI, 1.5-4.1) with platinum rechallenge / lurbinectedin / others, respectively (p = 0.025)., Discussion: Platinum-based rechallenge after a first-line CT-IO showed promising results despite particularly unfavorable characteristics within our real-word population. Lurbinectedin when used after IO demonstrated as low efficacy as other platinum-free regimens., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Setting: Mathematical modelling played an important role in the public health response to COVID-19 in Canada. Variability in epidemic trajectories, modelling approaches, and data infrastructure across provinces provides a unique opportunity to understand the factors that shaped modelling strategies., Intervention: Provinces implemented stringent pandemic interventions to mitigate SARS-CoV-2 transmission, considering evidence from epidemic models. This study aimed to summarize provincial COVID-19 modelling efforts. We identified modelling teams working with provincial decision-makers, through referrals and membership in Canadian modelling networks. Information on models, data sources, and knowledge translation were abstracted using standardized instruments., Outcomes: We obtained information from six provinces. For provinces with sustained community transmission, initial modelling efforts focused on projecting epidemic trajectories and healthcare demands, and evaluating impacts of proposed interventions. In provinces with low community transmission, models emphasized quantifying importation risks. Most of the models were compartmental and deterministic, with projection horizons of a few weeks. Models were updated regularly or replaced by new ones, adapting to changing local epidemic dynamics, pathogen characteristics, vaccines, and requests from public health. Surveillance datasets for cases, hospitalizations and deaths, and serological studies were the main data sources for model calibration. Access to data for modelling and the structure for knowledge translation differed markedly between provinces., Implication: Provincial modelling efforts during the COVID-19 pandemic were tailored to local contexts and modulated by available resources. Strengthening Canadian modelling capacity, developing and sustaining collaborations between modellers and governments, and ensuring earlier access to linked and timely surveillance data could help improve pandemic preparedness., (© 2024.

Background: Addressing gender inequities could be key to the elimination of vertical transmission of HIV. Women experiencing intimate partner violence (IPV) might be at an increased risk of vertical transmission due to their vulnerability to HIV acquisition and barriers to access to and retention in care. Sub-Saharan Africa, where IPV burden is among the highest globally, accounts for most new paediatric HIV infections. We aimed to examine the proportion of excess vertical transmission attributable to IPV in this region., Methods: In this modelling analysis, we created a probability tree model of vertical HIV transmission among women aged 15-49 years in 46 African countries. We estimated the proportion of vertical transmission attributable to past-year physical or sexual IPV, or both, as an age-standardised population attributable fraction (PAF) and as excess vertical transmission risk per 1000 births among women experiencing IPV. We incorporated perinatal and postnatal vertical transmission among women who acquired HIV before pregnancy, during pregnancy, and during breastfeeding. Fertility, HIV prevalence, HIV incidence, antiretroviral therapy (ART) uptake, and ART retention varied in the model by women's IPV experience. The model was parameterised using UNAIDS' 2023 Spectrum model data, WHO's Global Database on Violence Against Women, and the peer-reviewed literature. Uncertainty intervals (95% UI) were calculated through 1000 Monte Carlo simulations., Findings: Across 46 countries 13% (95% UI 6-21) of paediatric HIV infections in 2022 were attributed to IPV, corresponding to over 22 000 paediatric infections. The PAF ranged from 4% (2-7) in Niger to 28% (13-43) in Uganda. The PAF was highest among girls aged 15-19 years (20%, 8-33) and lowest among women aged 45-49 years (6%, 3-9). In southern Africa, where women's HIV prevalence is highest (23%), IPV led to 11 (5-20) additional infections per 1000 births among women affected by IPV., Interpretation: IPV might be responsible for one in eight paediatric HIV infections in sub-Saharan Africa. Ending IPV could accelerate vertical transmission elimination, especially among young women who bear the highest burden of violence., Funding: Canadian Institutes of Health Research, Canada Research Chair, and Fonds de recherche du Québec-Santé., Translations: For the French, Georgian and Spanish translations of the abstract see Supplementary Materials section., Competing Interests: Declaration of interests MM-G reports contractual arrangements from WHO and UNAIDS, and support for their research programme by a Canada Research Chair (Tier 2) in Population Health Modeling.

The International Association for the Study of Lung Cancer collaborated with the International Mesothelioma Interest Group to propose the first TNM stage classification system for diffuse pleural mesothelioma in 1995, accepted by the Union for International Cancer Control and the American Joint Committee on Cancer for the sixth and seventh edition stage classification manuals. The International Association for the Study of Lung Cancer Staging and Prognostic Factors Committee Mesothelioma Domain developed and analyzed an international registry of patients with pleural mesothelioma and updated TNM descriptors for the eighth edition of the stage classification system. To inform revisions for the forthcoming ninth edition of the TNM stage classification system, data submission was solicited for patients diagnosed between 2013 and 2022 with expanded data elements on the basis of the first project's exploratory analyses, including pleural thickness measurements, updated surgical nomenclature, and molecular markers. The resulting database consisted of a total of 3598 analyzable cases from Europe, Australia, Asia, North America, and South America, with a median age of 71 years (range: 18-99 y), 2775 (77.1%) of whom were men. With only 1310 patients (36.4%) undergoing curative-intent operations, this iteration of the database includes far more patients treated nonsurgically compared with prior. Four separate manuscripts on T, N, M, and stage groupings submitted to this journal will summarize analyses of these data and will serve collectively as the primary source of the proposed changes to the upcoming ninth edition of the pleural mesothelioma stage classification system., Competing Interests: Disclosure Dr. Hasegawa received an endowed course from Kubota Corporation.

Sexual violence against women is a human rights violation and public health concern, with serious implications for women's physical and mental health. Reducing non-partner sexual violence, including rape, sexual assault and other forms of non-contact sexual abuse, is one of the main indicators of the sustainable development goals. World Health Organization estimates, based on available prevalence data from 137 countries between 2000 and 2018, showed that, globally, 6% of women aged 15-49 years reported experiencing sexual violence in their lifetime from someone other than an intimate partner, with prevalence rates varying across regions. However, the reporting, measurement and documentation of the global extent of non-partner sexual violence against women is methodologically challenging, resulting in a gross underestimation of its magnitude and impact. To prevent and respond to this issue, policy-makers must consider interventions on education, access to relevant health-care services, public awareness, and effective and comprehensive legislation. To better estimate the prevalence of both sexual violence overall and non-partner sexual violence, it is essential to continue to strengthen the measurement of non-partner sexual violence, including the types of acts asked about and the mode of interviewing. Further research is needed to understand the cumulative impact of different forms of sexual violence on the lives of women and girls, including sexual violence during childhood and its associated risk with further exposure. Funding is required for more research and implementation of interventions to prevent and reduce all forms of violence against women and girls, including sexual violence., ((c) 2024 The authors; licensee World Health Organization.)

Aim and Rationale: Problems with manual dexterity and cognition impact the everyday performance of people with multiple sclerosis (PwMS). Accumulated findings point to the relationship between deficits in manual dexterity and auditory domains of cognition with a lack of evidence on visuospatial and verbal aspects of cognitive functioning. Therefore, this study explores the relationship between manual dexterity and cognition in a cohort of PwMS., Method: This cross-sectional study collected data from 63 PwMS aged 22 to 55 through a convenient sampling method. Participants were diagnosed with relapsing-remitting multiple sclerosis (RRMS). Cognition was measured using a multi-domain computerized cognitive testing, NeuroTrax, and manual dexterity was measured using a 9-hole peg assessment. Spearman correlation was used to identify the correlation among cognition subtests as well as with manual dexterity. Linear regression analysis was also conducted to identify whether manual dexterity predicts cognitive functioning., Results: A significant negative correlation was found between 9-hole peg scores and global cognitive scores (GCS), r = -0.34, p = 006. The manual dexterity scores were also shown to predict GCS, R 2 = 0.165, p = 0.001., Conclusion: Manual dexterity was found to not only predict cognitive dysfunction but was also associated with multiple cognitive domains. Understanding the relationship between manual dexterity and cognition and the inferred progression of deficits can assist clinicians to provide interventions at earlier stages of disease progression to potentially increase daily functioning and quality of life (QoL)., Competing Interests: Declaration of competing interest The authors report no potential conflict of interest., (Copyright © 2024.

Objectives: Our objectives were to characterize variations from standardized, evidence-based guidelines in the management of pediatric patients with diabetic ketoacidosis (DKA) based on initial presentation to a tertiary pediatric emergency department (PED) versus a community emergency department (OSH) and compare clinical outcomes., Methods: We conducted a retrospective study on children 18 years and younger with DKA who presented to an OSH or PED over a 3-year period. Treatments monitored for variation included intravenous fluid management, insulin delivery, and sodium bicarbonate administrations. Clinical outcomes included time to anion gap correction and on insulin infusion, hypokalemia, hypoglycemia, rapid serum glucose decline, cerebral edema, mechanical ventilation, mortality, and time from initial presentation to hospital discharge., Results: Children with DKA who presented to an OSH (n = 250) were more acidotic (pH 7.11 vs. 7.13, P = 0.001) and had larger anion gaps (28.8 vs. 25.5, P < 0.001) compared with children presenting to the PED (n = 237). The OSH patients were more likely to receive larger fluid boluses (>20 cc/kg or >1000 ml, 43% vs. 4%, P < 0.001), sodium bicarbonate (5% vs. 0%, P < 0.001), and intravenous bolus insulin (28% vs. 0%, P < 0.001). The OSH group were less likely to be started on maintenance intravenous fluids (70% vs. 99%, P < 0.001) or receive potassium in maintenance intravenous fluids (14% vs. 42%, P < 0.001). The OSH group had longer anion gap correction times (754 vs. 541 mins, P < 0.001), insulin infusion times (1018 vs. 854 min, P = 0.003), and times to hospital discharge (3358 vs. 3045 mins, P < 0.001). Incidence of hypokalemia, hypoglycemia, rapid glucose decline, cerebral edema, and deaths were similar between the 2 groups., Conclusions: Our study demonstrated significant variations in the initial management of pediatric DKA patients by OSH facilities that deviated from an evidence-based treatment pathway utilized by a PED. Statewide quality improvement initiatives could help improve the overall clinical care provided to pediatric DKA patients., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: During 2019-21, the AutoTest VIH, Libre d'accéder à la connaissance de son Statut (ATLAS) programme distributed around 380 000 HIV self-testing kits to key populations, including female sex workers, men who have sex with men, and their partners, in Côte d'Ivoire, Mali, and Senegal. We aimed to estimate the effects of the ATLAS programme and national scale-up of HIV self-test distribution on HIV diagnosis, HIV treatment coverage, HIV incidence, and HIV-related mortality., Methods: We adapted a deterministic compartmental model of HIV transmission in Côte d'Ivoire, parameterised and fitted to country-specific demographic, behavioural, HIV epidemiological, and intervention data in Côte d'Ivoire, Mali, and Senegal separately during 1980-2020. We simulated dynamics of new HIV infections, HIV diagnoses, and HIV-related deaths within scenarios with and without HIV self-test distribution among key populations. Models were separately parameterised and fitted to country-specific sets of epidemiological and intervention outcomes (stratified by sex, risk, age group, and HIV status, if available) over time within a Bayesian framework. We estimated the effects on the absolute increase in the proportion of people with HIV diagnosed at the end of 2021 for the ATLAS-only scenario and at the end of 2028 and 2038 for the HIV self-testing scale-up scenario. We estimated cumulative numbers of additional HIV diagnoses and initiations of antiretroviral therapy and the proportion and absolute numbers of new HIV infections and HIV-related deaths averted during 2019-21 and 2019-28 for the ATLAS-only scenario and during 2019-28 and 2019-38 for the HIV self-testing scale-up scenario., Findings: Our model estimated that ATLAS could have led to 700 (90% uncertainty interval [UI] 500-900) additional HIV diagnoses in Côte d'Ivoire, 500 (300-900) in Mali, and 300 (50-700) in Senegal during 2019-21, a 0·4 percentage point (90% UI 0·3-0·5) increase overall by the end of 2021. During 2019-28, ATLAS was estimated to avert 1900 (90% UI 1300-2700) new HIV infections and 600 (400-800) HIV-related deaths across the three countries, of which 38·6% (90% UI 31·8-48·3) of new infections and 70·1% (60·4-77·3) of HIV-related deaths would be among key populations. ATLAS would avert 1·5% (0·8-3·1) of all HIV-related deaths across the three countries during this period. Scaling up HIV self-testing would avert 16·2% (90% UI 10·0-23·1) of all new HIV infections during 2019-28 in Senegal, 5·3% (3·0-8·9) in Mali, and 1·6% (1·0-2·4) in Côte d'Ivoire. HIV self-testing scale-up among key populations was estimated to increase HIV diagnosis by the end of 2028 to 1·3 percentage points (90% UI 0·8-1·9) in Côte d'Ivoire, 10·6 percentage points (5·3-16·8) in Senegal, and 3·6 percentage points (2·0-6·4) in Mali., Interpretation: Scaling up HIV self-test distribution among key populations in western Africa could attenuate disparities in access to HIV testing and reduce infections and deaths among key populations and their partners., Funding: Unitaid, Solthis, the UK Medical Research Council Centre for Global Infectious Disease Analysis, the EU European & Developing Countries Clinical Trials Partnership programme, and the Wellcome Trust., Translation: For the French translation of the abstract see Supplementary Materials section., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2024 The Author(s).

Objectives: Contemporary research on the exposome, i.e. the sum of all the exposures an individual encounters throughout life and that may influence human health, bears the promise of an integrative and policy-relevant research on the effect of environment on health. Critical analyses of the first generation of exposome projects have voiced concerns over their actual breadth of inclusion of environmental factors and a related risk of molecularization of public health issues. The emergence of the European Human Exposome Network (EHEN) provides an opportunity to better situate the ambitions and priorities of the exposome approach on the basis of new and ongoing research., Methods: We assess the promises, methods, and limitations of the EHEN, as a case study of the second generation of exposome research. A critical textual analysis of profile articles from each of the projects involved in EHEN, published in Environmental Epidemiology, was carried out to derive common priorities, innovations, methodological and conceptual choices across EHEN and to discuss it., Results: EHEN consolidates its integrative outlook by reinforcing the volume and variety of data, its data analysis infrastructure and by diversifying its strategies to deliver actionable knowledge. Yet data-driven limitations severely restrict the geographical and political scope of this knowledge to health issues primarily related to urban setups, which may aggravate some socio-spatial inequalities in health in Europe., Conclusions: The second generation of exposome research doubles down on the initial ambition of an integrative study of the environmental effects of health to fuel better public health interventions. This intensification is, however, accompanied by significant epistemological challenges and doesn't help to overcome severe restrictions in the geographical and political scope of this knowledge. We thus advocate for increased reflexivity over the limitations of this conceptually and methodologically integrative approach to public and environmental health., (Copyright © 2024 The Authors.

Purpose: To explore the effects of the Personalized Citizen Assistance for Social Participation (APIC), an intervention adapted here for visual impairment, involving weekly stimulation sessions over six to twelve months, provided by trained and supervised attendants, on seven outcomes (social participation, leisure, independence, mobility, quality of life, health-related quality of life, and empowerment) in older adults with visual impairment, and to document its facilitators and barriers., Methods: A mixed-method design, which included a pre-experimental and an exploratory qualitative clinical research component, was used on 8 older adults (7 women) with visual impairment aged 70-86, and 8 attendants (5 women) aged 20-74. Before the intervention, directly after, and four months later, older adults completed questionnaires on the 7 outcomes. During the intervention, attendants completed diaries and participated in monthly meetings. Semi-structured interviews were administered to all participants after the intervention., Results: Social participation, leisure, mobility, quality of life and empowerment had increased immediately after the APIC. These improvements were still generally observed four months later. Participants reported that the APIC improved older adults' capabilities, social participation, and social environment., Conclusions: The APIC is a promising intervention which helps older adults with visual impairment to deal with social restrictions.

Introduction: Caregivers of autistic persons often face "courtesy stigma," a phenomenon by which caregivers experience stigma because of their association with a person whose disability may be stigmatized. Understanding the repercussions of this stigma is crucial not only for caregivers' mental health but also for the quality of care provided to their dependent. This study aimed to explore courtesy stigma among caregivers of autistic persons in Quebec, examining its prevalence and impact in order to identify groups that are particularly susceptible to negative outcomes., Methods: This study used a cross-sectional online survey methodology employing quota sampling to collect responses from 194 participants. Data were collected using a computer-assisted web interview (CAWI) platform. The impact of courtesy stigma was measured in terms of care burden, mental health, and overall well-being of caregivers., Results: The findings revealed that caregivers frequently experience rejection, isolation, and work-related challenges. Notably, caregivers' health was below average with the lowest reported health outcomes in Quebec. The caregivers who are the most vulnerable to negative outcomes included female caregivers, those aged 45 or older, financially strained households, caregivers of children requiring elevated levels of support, caregivers who isolated due to their autistic dependents, and those who experienced stigmatization directed at themselves or their children in the form of rejection.Interestingly, 60% of respondents reported that the caregiving burden was "not at all" to "somewhat" difficult, raising questions about factors that may mitigate caregiving challenges over time., Conclusion: Negative outcomes from courtesy stigma vary depending on certain risk factors and individual characteristic. This study underscores the need for targeted public policies and interventions, particularly for those at a higher risk of experiencing the negative effects of courtesy stigma on the burden of care, overall health, and mental health. By tailoring resources and support for these priority groups, we can better address the challenges faced by families of autistic persons., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Valderrama, Nikièma, Forgeot d’Arc, Guerrero and Giroux.)

Background: Canadian Arctic communities have experienced sustained syphilis transmission, with diagnoses rates 18-times higher than the national average. Remoteness from laboratory facilities leads to delays between syphilis screening and treatment, contributing to onward transmission. Rapid diagnostic tests can eliminate treatment delays via testing at the point-of-care. This study aims to describe syphilis diagnostic gaps and to estimate the impact of introducing rapid diagnostic tests at the point-of-care on syphilis transmission., Methods: To assess the population-level impact of deploying rapid diagnostic tests, an individual-based model was developed using detailed surveillance data, population surveys, and a prospective diagnostic accuracy field study. The model was calibrated to syphilis diagnoses (2017-2022) from a community of approximately 1,050 sexually active individuals. The impacts of implementing rapid diagnostic tests using whole blood (sensitivity: 92% for infectious and 81% for non-infectious syphilis; specificity: 99%) from 2023 onward was calculated using the annual median fraction of cumulative new syphilis infections averted over 2023-2032., Findings: The median modeled syphilis incidence among sexually active individuals was 44 per 1,000 in 2023. Males aged 16-30 years exhibited a 51% lower testing rate than that of their female counterparts. Maintaining all interventions constant at their 2022 levels, implementing rapid diagnostic tests could avert a cumulative 33% (90% credible intervals: 18-43%) and 37% (21-46%) of new syphilis infections over 5 and 10 years, respectively. Increasing testing rates and contact tracing may enhance the effect of rapid diagnostic tests., Interpretation: Implementing rapid diagnostic tests for syphilis in Arctic communities could reduce infections and enhance control of epidemics. Such effective diagnostic tools could enable rapid outbreak responses by providing same-day testing and treatment at the point-of-care., Funding: Canadian Institutes of Health Research., Competing Interests: MM-G's research program is supported by Canadian Institutes of Health Research (CIHR) and a Canada Research Chair (Tier II) in Population Health Modeling.

The analysis of protein dynamics or turnover in patients has the potential to reveal altered protein recycling, such as in Alzheimer's disease, and to provide informative data regarding drug efficacy or certain biological processes. The observed protein dynamics in a solid tissue or a fluid is the net result of not only protein synthesis and degradation but also transport across biological compartments. We report an accurate 3-biological compartment model able to simultaneously account for the protein dynamics observed in blood plasma and the cerebrospinal fluid (CSF) including a hidden central nervous system (CNS) compartment. We successfully applied this model to 69 proteins of a single individual displaying similar or very different dynamics in plasma and CSF. This study puts a strong emphasis on the methods and tools needed to develop this type of model. We believe that it will be useful to any researcher dealing with protein dynamics data modeling.

Background and Objectives: Aneurysmal surgery is technically complex, and surgeon experience is an important factor in therapeutic success, but training young vascular neurosurgeons has become a complex paradigm. Despite new technologies and simulation models, cadaveric studies still offer an incomparable training tool with perfect anatomic accuracy, especially in neurosurgery. The use of human placenta for learning and improving microsurgical skills has been previously described. In this article, we present a comprehensive simulation model with both realistic craniotomy exposure and vascular handling consisting of a previously prepared and perfused human placenta encased in a human cadaveric specimen., Methods: Humans' placentas from the maternity and cadaveric heads from the body donation program of the anatomy laboratory were used. Placentas were prepared according to the established protocol, and aneurysms were created by catheterization of a placental artery. Ten participants, including senior residents or young attendees, completed an evaluation questionnaire after completing the simulation of conventional unruptured middle artery aneurysm clipping surgery from opening to closure., Results: The skin incision, muscle dissection, and craniotomy were assessed as very similar to reality. Brain tissue emulation and dissection of the lateral fissure were judged to be less realistic. Vascular management was evaluated as similar to reality as closure. Participants uniformly agreed that this method could be implemented as a standard part of their training., Conclusion: This model could provide a good model for unruptured aneurysm clipping training., (Copyright © Congress of Neurological Surgeons 2024.

Introduction: HIV self-testing (HIVST) is a promising strategy to improve diagnosis coverage among key populations (KP). The ATLAS (Auto Test VIH, Libre d'Accéder à la connaissance de son Statut) programme implemented HIVST in three West African countries, distributing over 380,000 kits up between 2019 and 2021, focussing on community-led distribution by KP to their peers and subsequent secondary distribution to their partners and clients. We aim to evaluate the cost-effectiveness of community-led HIVST in Côte d'Ivoire, Mali and Senegal., Methods: An HIV transmission dynamics model was adapted and calibrated to country-specific epidemiological data and used to predict the impact of HIVST. We considered the distribution of HIVST among two KP-female sex workers (FSW), and men who have sex with men (MSM)-and their sexual partners and clients. We compared the cost-effectiveness of two scenarios against a counterfactual without HIVST over a 20-year horizon (2019-2039). The ATLAS-only scenario mimicked the 2-year implemented ATLAS programme, whereas the ATLAS-scale-up scenario achieved 95% coverage of HIVST distribution among FSW and MSM by 2025 onwards. The primary outcome is the number of disability-adjusted life-years (DALY) averted. Scenarios were compared using incremental cost-effectiveness ratios (ICERs). Costing was performed using a healthcare provider's perspective. Costs were discounted at 4%, converted to $USD 2022 and estimated using a cost-function to accommodate economies of scale., Results: The ATLAS-only scenario was highly cost-effective over 20 years, even at low willingness-to-pay thresholds. The median ICERs were $126 ($88-$210) per DALY averted in Côte d'Ivoire, $92 ($88-$210) in Mali and 27$ ($88-$210) in Senegal. Scaling-up the ATLAS programme would also be cost-effective, and substantial epidemiological impacts would be achieved. The ICERs for the scale-up scenario were $199 ($122-$338) per DALY averted in Côte d'Ivoire, $224 ($118-$415) in Mali and $61 ($18-$128) in Senegal., Conclusions: Both the implemented and the potential scale-up of community-led HIVST programmes in West Africa, where KP are important to overall transmission dynamics, have the potential to be highly cost-effective, as compared to a scenario without HIVST. These findings support the scale-up of community-led HIVST to reach populations that otherwise may not access conventional testing services., (© 2024 The Author(s).

Health professions educators often use social media to share knowledge; however, it is unclear what specific dissemination and knowledge translation (KT) processes are occurring and the implications of this sharing for health professions education (HPE). This study explored how educators have used social media as a mechanism of dissemination and KT in the literature. A critical scoping review methodology, informed by Engeström's Activity Theory, was employed. Twelve databases were searched and studies that: (a) addressed health professions educators; (b) described the use of social media for dissemination or KT; (c) focused on a regulated health profession; (d) focused on undergraduate or graduate education; and (e) were published in English or French between 2011 and 2021 were included. Data were analyzed using numerical and qualitative content analyses. Of the 4859 articles screened, 37 were eligible for inclusion. Social media may facilitate knowledge sharing in HPE, but there is a lack of conceptual clarity on what is meant by 'dissemination' and 'KT'. Who is responsible for sharing knowledge, what knowledge is being shared, and the target audiences are not always clear. Multiple factors (e.g., affordances, opportunity costs) influence how social media is used as a mechanism of dissemination, and it remains unclear whether and how it is used as a mechanism of KT. Concepts like KT and dissemination, which are often borrowed from other disciplines, must be critically evaluated for their relevance and suitability if they are to be appropriately applied to HPE and in particular to social media. Educators looking to use social media to teach students about KT should consider whether this use of technology truly aligns with their stated learning outcomes., (© 2023.

Introduction: The TNM classification of lung cancer is periodically revised. The International Association for the Study of Lung Cancer collected and analyzed a new database to inform the forthcoming ninth edition of the TNM classification. The results are herewith presented., Methods: After exclusions, 76,518 patients from a total of 124,581 registered patients were available for analyses: 58,193 with clinical stage, 39,192 with pathologic stage, and 62,611 with best stage NSCLC. The proposed new N2 subcategories (N2a, involvement of single ipsilateral mediastinal or subcarinal nodal station, and N2b, involvement of multiple ipsilateral mediastinal nodal stations with or without involvement of the subcarinal nodal station) and the new M1c subcategories (M1c1, multiple extrathoracic metastases in one organ system, and M1c2, multiple extrathoracic metastases in multiple organ systems) were considered in the survival analyses. Several potential stage groupings were evaluated, using multiple analyses, including recursive partitioning, assessment of homogeneity within and discrimination between potential groups, clinical and statistical significance of survival differences, multivariable regression, and broad assessment of generalizability., Results: T1N1, T1N2a, and T3N2a subgroups are assigned to IIA, IIB, and IIIA stage groups, respectively. T2aN2b and T2bN2b subgroups are assigned to IIIB. M1c1 and M1c2 remain in stage group IVB. Analyses reveal consistent ordering, discrimination of prognosis, and broad generalizability of the proposed ninth edition stage classification of lung cancer., Conclusions: The proposed stages for the ninth edition TNM improve the granularity of nomenclature about anatomic extent that has benefits as treatment approaches become increasingly differentiated and complex., Competing Interests: Disclosure Dr. Nishimura and Ms. Giroux report that statistical consulting by Cancer Research And Biostatistics (CRAB) employees for data collection, analysis, and manuscript preparation in the Staging Project is funded by the International Association for the Study of Lung Cancer (IASLC).
