ABSTRACT

IMPORTANCE: Approximately 10% of cancers are attributable to heritable germline variants, yet identification of individuals at risk remains suboptimal.

OBJECTIVE: To assess the feasibility of personal history and family health history (FHH) risk assessment technology via the electronic medical record (EMR) to enhance identification of patients at risk for a broad array of inherited cancer syndromes.

DESIGN, SETTING, AND PARTICIPANTS: This single-arm, nonrandomized clinical trial was completed from October 1, 2021, to September 1, 2023, with no follow-up period in unselected patients receiving care at Vanderbilt University Medical Center. Adult patients (aged ≥18 years) were invited through their EMR patient portals to complete an eligibility survey. Eligible participants completed the survey, were English speaking, and had no prior genetic counseling. The data analysis was performed between August 15 and November 7, 2025.

INTERVENTION: Electronic medical record-integrated risk assessment platform that collected self-reported personal history and FHH to assess risk for 24 hereditary cancer syndromes.

MAIN OUTCOMES AND MEASURES: The primary outcome was the completion rate of the risk assessment platform. Secondary outcomes included the percentage of newly identified participants meeting guideline criteria for genetic counseling and whether previsit FHH collection increased genetic counseling capacity by decreasing time spent in counseling.

RESULTS: A total of 1685 patients were consented to participate (mean [SD] age, 55.4 [15.1] years; 1217 female [72.2%]; 95 of Black or African American [5.6%] 1405 of White [83.4%], and 181 of other [multiracial, other, or unknown] [10.6%] race; 38 of Hispanic or Latino [2.3%], 1388 of non-Hispanic or Latino [82.4%], and 111 of unknown [6.6%] ethnicity). Among participants consented, 1483 (88.0%) were provided access to the risk assessment, 1106 (74.6%) started the assessment, 636 (57.5%) completed it, and 544 (49.1%) received a risk report. Younger age and unknown race and ethnicity were the only significant variables associated with completion (mean [SD] age, 53.5 [15.3] vs 56.9 [14.8] years for completers vs noncompleters, respectively; unknown race, 77 [14.2%] vs 43 [7.6%] for noncompleters; unknown ethnicity, 49 [9.0%] vs 20 [3.6%] for completers vs noncompleters, respectively). Among participants who completed the risk assessment, 155 (28.5%) met guideline criteria for genetic counseling, yet 74 (47.7%) were previously identified as at risk by billing codes. A total of 31 participants (20.0%) eligible for genetic counseling attended. Manual outreach efforts and counseling duration did not differ between risk assessment-assisted and usual care visits.

CONCLUSIONS AND RELEVANCE: In this nonrandomized clinical trial, almost one-third of the population met national genetic counseling criteria for an inherited cancer syndrome, highlighting a substantial gap in usual care identification. Integrating patient-facing FHH collection and assessment tools for primary care patients improves inherited cancer risk identification and highlights opportunities to further enhance both risk assessment processes and genetic counseling attendance.

ABSTRACT

IMPORTANCE: Studies have demonstrated lower odds of survival from out-of-hospital cardiac arrest (OHCA) during nighttime hours, but this has not been studied in North America since 2013, and it is unclear what factors might explain this survival difference.

OBJECTIVE: To identify whether OHCA survival during nighttime hours remains lower than during daytime hours using contemporary data and whether it can be explained by variable patient physiology or emergency care factors.

DESIGN, SETTING, AND PARTICIPANTS: This cohort study included adults (aged ≥18 years) with OHCA in the Cardiac Arrest Registry for Enhanced Survival from 2013 to 2024.

EXPOSURE: Daytime was defined as 7:00 am to 10:59 pm, and nighttime was defined as 11:00 pm to 6:59 am.

MAIN OUTCOME AND MEASURES: Primary outcomes were sustained return of spontaneous circulation (ROSC) and neurologically favorable survival (Cerebral Performance Category score of 2 or more). A multilevel mixed-effects logistic regression model with prehospital agency as a random effect and patient or treatment characteristics as fixed effects was used. A similar analysis of postresuscitation survival was performed among patients with sustained ROSC, adjusting for the time-to-cardiopulmonary resuscitation interval and defibrillation status. A mediation analysis was performed to identify whether the prehospital response interval mediates the association.

RESULTS: Of 1 151 845 patients in the registry, 874 415 were eligible and included in the analysis, and the median (IQR) age in the cohort was 64 (52-75) years with 557 515 males (63.8%) and 181 878 Black or African American patients (20.8%), 146 352 Hispanic or Latino patients (16.7%), and 447 646 White patients (51.2%). A minority of OHCA responses occurred at nighttime (241 967 [27.7%]), and the odds of sustained ROSC and neurologically favorable survival were lower at nighttime than daytime (sustained ROSC: 62 548 [25.8%] vs 193 486 [30.6%]; adjusted odds ratio [aOR], 0.85; 95% CI, 0.84-0.86; neurologically favorable survival: 16 234 [6.7%] vs 58 542 [9.3%]; aOR, 0.84; 95% CI, 0.82-0.86). Among those with sustained ROSC, the odds of postresuscitation survival at nighttime were also lower than daytime (aOR, 0.93; 95% CI, 0.90-0.95). The prehospital response interval partially mediated the nighttime survival disadvantage, with approximately 12.6% of the total effect mediated by the response interval.

CONCLUSIONS AND RELEVANCE: In this cohort study of OHCA, nighttime response was associated with lower adjusted odds of sustained ROSC, neurologically favorable survival, and postresuscitation survival. Emergency care factors accounted for only a portion of the decreased odds of survival at nighttime.

ABSTRACT

IMPORTANCE: The US Department of Veterans Affairs (VA) Whole Health approach was congressionally mandated in 2016 for patients with chronic pain receiving care in VA hospitals, but no randomized clinical trials have tested its benefits.

OBJECTIVE: To evaluate the effectiveness of a whole health team intervention in VA patients with chronic pain compared with cognitive behavioral therapy and with usual care, and to evaluate the effectiveness of cognitive behavioral therapy compared with usual care in reducing long-term pain interference.

DESIGN, SETTING, AND PARTICIPANTS: This randomized clinical trial involving 6 VA health systems in the US enrolled participants between September 18, 2020, and January 19, 2024. Final follow-up occurred on January 27, 2025. Analyses took place between April 1, 2025, and February 3, 2026. Participants were patients with chronic pain receiving VA primary care.

INTERVENTIONS: Patients with chronic pain were randomized (11:11:2) to receive a whole health team intervention (n = 343), cognitive behavioral therapy for chronic pain delivered in group sessions (n = 339), or usual care (n = 82) for 12 months. The whole health team included a primary physician or nurse practitioner, a second clinician providing nonpharmacological or integrative pain care, and a coach. The team provided interdisciplinary, individualized care consistent with the VA Whole Health model to attain personal health goals aligned with patients’ personal values and life goals.

MAIN OUTCOMES AND MEASURES: The primary outcome was the Brief Pain Inventory interference (BPI-I) subscale score (range, 0-10 points; higher scores indicate worse interference from pain; minimal clinically important difference, 1.0) at 12 months.

RESULTS: Of 764 randomized patients (mean [SD] age, 60.5 [12.3] years; 66.5% were men), 632 (82.7%) completed 12-month follow-up. At 12 months, the whole health group had significantly improved pain interference scores (from 6.6 to 4.9) compared with the cognitive behavioral therapy (from 6.4 to 5.5) (mean difference, -0.58 [97% CI, -1.11 to -0.05]; P = .02) and usual care (from 6.4 to 5.7) (mean difference, -0.77 [99% CI, -1.40 to -0.15]; P = .002) groups. At 12 months, cognitive behavioral therapy did not improve pain interference scores significantly more than usual care (mean difference, -0.19 [99% CI, -0.89 to 0.50]; P = .46). The most common adverse event was suicidal ideation, which occurred in 15.9% of patients in the cognitive behavioral therapy group, 13.7% in the whole health team group, and 13.4% in the usual care group.

CONCLUSIONS AND RELEVANCE: These results support use of the whole health team approach to attain a statistically significant but small improvement in pain interference in VA patients with chronic pain.

ABSTRACT

This single-site, pilot-scale randomized controlled study intended to evaluate the effects of a self-determination theory-informed (D6 gamification model-based) gamified breastfeeding counselling program on breastfeeding self-efficacy, breastfeeding success, and breast-related problems in postpartum participants. A pretest-posttest randomized controlled trial was conducted with 60 pregnant individuals recruited from a single university-affiliated private hospital in Türkiye, using a pilot-scale parallel group design. Participants were assigned to experimental (n = 30) and control (n = 30) groups by block randomization that was performed by an independent statistician. Due to the behavioural nature of the intervention, participant blinding was not feasible; however, outcome analyses were conducted by a blinded biostatistician. The intervention group received a digitally delivered gamified breastfeeding counselling program from gestational week 35 until week 2 postpartum, while the control group received routine prenatal and postnatal care. Data were obtained for validated measures of breastfeeding self-efficacy, breastfeeding success, and breast-related problems. Descriptive and inferential statistical analyses were conducted with SPSS 28.0 software. At week 2 postpartum, the mean breastfeeding self-efficacy scale-short form scores were significantly higher in the gamified counselling group than the control group (63.6 ± 6.2 versus 54.3 ± 8.4, P < .001, Cohen’s d = 1.26). Breastfeeding performance also favoured the intervention group, with higher infant breastfeeding assessment tool scores (8.6 ± 1.1 versus 7.3 ± 1.4, P < .001) and LATCH breastfeeding assessment scores (9.3 ± 0.7 versus 8.4 ± 1.1, P = .002). Furthermore, breast fullness severity that was assessed using a dichotomous self-reported outcome (present/absent) checklist in which higher scores indicate more severe fullness, was lower in the intervention group than the control group (2.5 ± 1.1 versus 4.0 ± 1.2, P < .001). Gamified breastfeeding counselling was effective in enhancing breastfeeding self-efficacy and breastfeeding success and reduced common breast-related problems. These findings provide preliminary evidence supporting the feasibility and short-term benefits of integrating gamification-based strategies into breastfeeding education, warranting larger multicenter studies with extended follow-up.

ABSTRACT

BACKGROUND: The accurate assessment of infraosseous periodontal defects is crucial for effective diagnosis and treatment planning. Cone-beam computed tomography (CBCT) enables detailed imaging of these defects; however, to leverage their full potential, CBCT images must be reconstructed in 3 dimensions (3D). Manual and semi-automatic (SA) segmentation methods are time-consuming and prone to human error. This study aimed to evaluate the performance of a deep learning (DL) model in segmenting mandibular infraosseous periodontal defects on CBCT scans.

METHODS: A multi-stage Segmentation Residual Network (SegResNet)-based DL model was used to segment CBCT scans from patients with stages III to IV periodontitis. Linear and volumetric measurements of infraosseous defects from DL-generated 3D models were compared to those obtained using SA segmentation. The depth (INFRA), width (WIDTH), angle (ANGLE), and volume of 48 infraosseous defects were assessed on both DL and SA segmentations.

RESULTS: Measurements made on the DL and SA segmentations correlated strongly. The intraclass correlation coefficient (ICC) was 0.941 (p < 0.0001) for INFRA, 0.943 (p < 0.0001) for WIDTH, 0.889 (p < 0.0001) for ANGLE, and 0.948 (p < 0.0001) for defect volume. These results indicate high reliability of the DL model in capturing key characteristics of infraosseous periodontal defects.

CONCLUSIONS: These findings support the use of DL-based CBCT segmentation as a valuable tool for enhancing periodontal diagnosis. However, as this study was limited to mandibular defects, applicability to maxillary cases remains to be validated.

ABSTRACT

BACKGROUND: Cytomegalovirus (CMV) infection remains one of the most prevalent and consequential post solid organ transplant (SOT) infections. Treatment is often challenging, especially when dealing with refractory and resistant CMV infections.

METHODS: We performed a retrospective multicenter cohort study of SOT recipients with clinically significant CMV infection (csCMVi) during 2010-2016. The primary outcome was early refractory CMV infection and secondary outcomes were drug resistance, CMV recurrence, and mortality. Analysis was done with Kaplan-Meier, univariable logistic regression analysis, and multivariable Cox regression.

RESULTS: We included 145 SOT recipients with csCMVi, majority were liver transplant (49%). Most common induction was an anti-IL-2 antibody (43.9%). The majority (n = 82; 56.5%) were CMV D+/R- mismatch and presented asymptomatic infection (50.3%). After the initial 3 weeks of antiviral therapy, 13 (8.9%) patients had probable refractory csCMVi; most of them (10 [76.9%]) were CMV D+/R- mismatch. Longer time after transplant had lower risk (OR 0.68; CI 0.48-0.95, p = 0.029) while lower absolute lymphocyte count (ALC) had a higher risk of early refractory csCMVi (OR 1.54; CI 1.01-2.44, p = 0.048). Drug-resistant csCMVi occurred in 7 patients (4.8%); a high initial CMV DNA level was associated with resistant csCMVi (OR 2.00; CI 1.08-3.93, p = 0.031). 25 patients (17.2%) experienced recurrent csCMVi within 6 months. 30 patients (20.7%) died; refractory, resistant or recurrent CMV infections were not associated with mortality.

CONCLUSION: Refractory csCMVi is associated with a low ALC and an earlier onset after transplant. Resistant csCMVi is associated with high initial CMV DNA levels. Recurrence of csCMVi is common and potentially associated with low ALC at the end of antiviral treatment.

ABSTRACT

ABSTRACT: High-risk fertility behavior is a leading contributor to adverse maternal and child health outcomes. This study assessed the prevalence and determinants of high-risk fertility behavior among reproductive-age women in sub-Saharan Africa. We conducted a secondary analysis of Demography and Health Survey data from eight sub-Saharan African countries with extremely high or very high maternal mortality. A weighted sample of 78,353 reproductive-age women who had given birth in the five years preceding the survey was included. A multilevel mixed-effects binary logistic regression model was used to identify individual- and community-level factors associated with high-risk fertility behavior, accounting for the hierarchical nature of the data. Statistical significance was determined using AOR with a 95% CI and a p-value ≤ 0.05. The overall prevalence of high-risk fertility behavior was 71.46% (95% CI: 71.14%, 71.77%)), with the highest prevalence observed in Chad (87.75%) and the lowest in Lesotho (40.49%). Key individual-level determinants included women’s and husbands’ education, religion, wealth status, child sex, marital status, mobile phone and internet use, antenatal care attendance, history of pregnancy termination, and contraceptive use. At the community level, low poverty was associated with a reduced likelihood of high-risk fertility behavior. The prevalence of high-risk fertility behavior remains high in countries with extremely high and very high maternal mortality countries, highlighting a need to address it through urgent and concerted interventions. Policymakers and planners should prioritize interventions targeting the key determinants high-risk fertility behavior to curb its occurrence and improve maternal and child health outcomes.

LAY SUMMARY: High-risk fertility behavior (HRFB) is defined as having children at very young or older ages, having many births, or spacing pregnancies too closely, which can lead to serious health problems for mothers and children. This study aimed to determine the magnitude of high-risk fertility behaviors and the factors that affect the behavior among women in eight sub-Saharan African countries with very high maternal mortalities. Using data from over 78,000 women, we analyzed both individual and community-level characteristics linked to HRFB. This study found that about 71% of women had HRFB. The highest rates were in Chad, and the lowest were in Lesotho. Factors such as low education, poverty, limited use of antenatal care, lack of contraception, and reduced access to mobile phones or the internet increased the likelihood of HRFB. Communities with lower poverty showed lower rates. These findings underscore the need for targeted policies and programs to reduce HRFB and improve maternal and child health.

ABSTRACT

SETTING: In France, participation rates in breast cancer screening have been decreasing, along with socio-territorial inequalities. To enhance women’s access to breast cancer screening, an interventional research project was implemented to assess the effectiveness, efficiency, and optimal modalities of a mobile mammography unit for women living remotely in Normandy.

INTERVENTION: The randomized cluster trial was directed towards rural women. Before deploying the mobile unit, an intervention theory was developed. The principles of action to reduce inequalities, the definition and standardization of interventions, and the link to behavior change theories to establish causal mechanisms were integrated into a single model. We aimed to produce new knowledge on these mechanisms and develop intervention evaluations.

OUTCOMES: Using the key function/implementation/context model, the key functions of the expected intervention were listed, linked to the behavior change technique and theoretical domain framework, and finally to the capability, opportunity, motivation-behavior model components. The mechanisms and levers that can improve access to breast cancer screening are also described. This approach also allowed the standardization of stakeholders’ implications and their corresponding actions. Concrete interventions implemented included scheduling appointments at the mobile unit and implementing a suite of measures to improve the information provided to women regarding breast cancer screening.

IMPLICATIONS: This theoretical framework should be compared with interventions carried out during the deployment of mobile units. Various elements interact dynamically with and alter originally planned interventions. This experiential feedback may inform decisions on the transferability of mobile mammography units to other contexts. TRIAL REGISTRATION : This study was registered at ClinicalTrials.gov (registration date: December 21, 2021; registration number: NCT05164874).

ABSTRACT

OBJECTIVES: Compared to the general population, persons with intellectual disability (ID) have a similar cancer rate, but cancer is often discovered at a later stage. Adults with ID show lower participation in organized screenings for breast, cervical, and colorectal cancer. Here we tested an intervention to increase cancer screening knowledge and intention to participate among persons with ID.

METHODS: An open-label cluster randomized controlled trial was co-constructed with people having ID. Participants with ID underwent interventions about cancer screening or oral hygiene, using PowerPoint presentations, booklets, dice games, workshops, films, and discussions. Both groups completed a questionnaire two weeks before the intervention and at 15 min, three months, and one year after the intervention, which evaluated their knowledge gain and intention to participate in cancer screenings.

RESULTS: At 15 min, three months, and one year after the intervention, participants in the cancer group showed significantly improved cancer screening knowledge (p < 0.001). The intention to participate in screenings was increased on the intervention date (p < 0.001), but this change was non-significant three months later, and observed as a trend at one year (p = 0.068). A steering group of persons with ID gave advice regarding participant recruitment, conducting sessions, and modifying the film scenario, PowerPoint presentation, and questionnaire. Persons with ID co-constructed the booklet on cancer screening and acted in the film.

CONCLUSION: Participation of persons with ID greatly improved the study efficacy. This research provides strong evidence supporting direct interventions for people with intellectual disability to increase their participation in organized cancer screening.

ABSTRACT

Some occupational cancers appear decades after exposure. Diseases are therefore often detected during the retirement period. This disconnect raises the question of how to best protect the occupational health of retirees who are no longer in the workplace and are unlikely to have routine health monitoring by occupational physicians, even though they carry an increased risk of cancer resulting from past occupational exposure. Some countries and jurisdictions are already working to address these challenges. Since 1995, France has had a post-professional monitoring system, which has been the subject of the Rispop29 research since 2021. The results of this research serve as a basis for investigating the possibility of such a system in Ontario, where a register of workers exposed to asbestos already exists and could serve as a basis for ongoing monitoring in the retirement years. The results suggest that such an initiative would be of interest from an epidemiological and medical point of view, and that it would go beyond the single case of asbestos exposure.
