Are we ready for human papillomavirus testing? Assessment of patient knowledge of and preferences for cervical cancer screening in Ontario.

OBJECTIVE: To determine patient knowledge and preferences about primary human papillomavirus (HPV) testing. DESIGN: Cross-sectional survey. SETTING: Two family practice clinics (urban and suburban) and the social media platforms of 2 hospitals in the greater Toronto area between January and February 2023. PARTICIPANTS: A total of 413 Ontario residents aged 25 to 69 years, with a cervix, who qualified for Papanicolaou (Pap) screening and could communicate in English. METHODS: Electronic survey containing questions about knowledge of, and preferences for, cervical cancer screening, including types of screening and screening intervals, and about education related to HPV and screening intervals. MAIN FINDINGS: Of 441 potential participants, 426 were eligible and consented to participate in the study; ultimately 413 provided completed or partially completed surveys (96.9% response rate). Of those who completed a recent Pap test, 57.8% (208 of 360) knew of HPV testing. Initially, 27.8% thought HPV testing was better than Pap testing for cervical cancer screening. After learning HPV tests exist and have self-sampling options, most participants preferred HPV testing (self-sampling 46.3%, provider sampling 34.1%). Annual cervical cancer screening was preferred by 50.1% of participants despite knowing that, for most people, Pap tests should be conducted every 3 years (74.8%). After learning about HPV testing, participants were more likely to prefer 5-year screening intervals (43.8%); however, those in the family practice group were still more likely to prefer 3-year intervals compared with those in the social media group (P<.01). CONCLUSION: Participants in this study identified a preference for HPV testing and self-sampling options. Concerns were raised about extended screening intervals and the safety of self-collected samples that need to be addressed in public health education initiatives during rollout of new screening programs.

Transitioning sleeping position detection in late pregnancy using computer vision from controlled to real-world settings: an observational study.

Sleeping on the back after 28 weeks of pregnancy has recently been associated with giving birth to a small-for-gestational-age infant and late stillbirth, but whether a causal relationship exists is currently unknown and difficult to study prospectively. This study was conducted to build a computer vision model that can automatically detect sleeping position in pregnancy under real-world conditions. Real-world overnight video recordings were collected from an ongoing, Canada-wide, prospective, four-night, home sleep apnea study and controlled-setting video recordings were used from a previous study. Images were extracted from the videos and body positions were annotated. Five-fold cross validation was used to train, validate, and test a model using state-of-the-art deep convolutional neural networks. The dataset contained 39 pregnant participants, 13 bed partners, 12,930 images, and 47,001 annotations. The model was trained to detect pillows, twelve sleeping positions, and a sitting position in both the pregnant person and their bed partner simultaneously. The model significantly outperformed a previous similar model for the three most commonly occurring natural sleeping positions in pregnant and non-pregnant adults, with an 82-to-89% average probability of correctly detecting them and a 15-to-19% chance of failing to detect them when any one of them is present.

Common sleep disorders in pregnancy: a review.

In this review, we provide a comprehensive overview of common sleep disorders during pregnancy, including their characterization, prevalence, risk factors, and possible contribution to maternal and fetal outcomes. We conducted a quasi-systematic literature search of the MEDLINE database and identified 744 studies from 1991 through 2021, inclusive, that met our inclusion criteria. We synthesized the existing literature on sleep disorders during pregnancy and highlighted controversies, research gaps, and needed clinical developments. Our review covers a range of sleep disorders, including insomnia, obstructive sleep apnea, restless legs syndrome, and circadian rhythm disorders. We discuss the prevalence of these disorders in pregnancy and their potential impact on maternal and fetal health outcomes. We also explore the relationship between sleep disorders, pre-pregnancy comorbidities such as obesity, and pregnancy-related conditions such as gestational diabetes mellitus and preeclampsia. In addition to summarizing the existing literature on sleep disorders during pregnancy, we also highlight opportunities for further research in this area. We suggest that future studies should strive to employ validated and objective measurement tools for sleep disorders and prioritize utilization of longitudinal methods with participant follow-up through postpartum, mid-life, menopause, and beyond. We also put forward investigation into the impact of circadian rhythm disruption on reproductive physiology and early pregnancy outcomes as an area of important work. Overall, our review provides valuable insights on sleep and reproduction and into common sleep disorders during pregnancy and their potential impact on maternal and fetal health outcomes.

"Check Your Vulva"-A Patient Education and Virtual Vulva Care Pilot Project.

OBJECTIVE: The aim of the study is to identify whether vulvar self-examination learned from a web site could lead to a self-identification of vulvar lesions and the feasibility of virtual vulvar care with patient submitted photos. MATERIALS AND METHODS: The study used a prospective cohort design in a tertiary academic hospital over a 1-year period. Eligible participants who self-identified a vulvar lesion/skin changes were invited to send vulvar photos through a secure patient portal and schedule a phone consult to discuss diagnosis/management. Clinical data, photo interpretability, and patient satisfaction measures were collected. Self-referral patients versus vulva clinic waitlist patients were analyzed separately. RESULTS: Few people were interested in submitting vulvar photos online. Twenty-eight participants directly contacted the study, 8 consented, and 6 sent in vulvar photos. Forty four of 476 on the waitlist consented but only 24 of 44 sent in photos (5% of waitlist patients). The median time for a virtual assessment was 7 days for study participants while it was 18 months for the in-person usual care pathway. Most patient submitted photos were assessable. However, 60% participants needed help from another person to take the photos. More than 90% of patients required an in-person visit for their vulvar condition/concerns. While most patients were happy with the virtual process, 58% rated their satisfaction with the ease of taking photos of the genital region as "fair" or "poor." CONCLUSIONS: Virtual care with photos/phone calls might be feasible, although most patients are unlikely to participate. Because of patient discomfort, unease with taking photos, and patient privacy concerns, vulvar care should continue to be in-person for most new consults.

Sex Disparity in Liver Transplant and Access to Living Donation.

Importance: The Model for End-stage Liver Disease (MELD)-based organ allocation system has significantly decreased mortality on the transplant waiting list for patients with end-stage liver disease. However, women have remained at a disadvantage with respect to access to deceased donor liver transplant (DDLT) even after introduction of the MELD score for organ allocation. Objective: To determine whether availability of living donation in a transplant program can offset inequity in liver transplant (LT) allocation for women. Design, Setting, and Participants: This cohort study retrospectively analyzed adult patients listed for LT at the University Health Network in Toronto, Ontario, Canada. Patients included had a potential living donor (pLD) at the moment of listing. This study was performed from November 13, 2012, to May 31, 2019. A total of 1289 listed patients (830 men; 459 women) were analyzed during the study period. Main Outcomes and Measures: This study performed survival analysis and competing-risk analysis to delineate how access to livers from living donors was associated with events in women vs men on the transplant waiting list (LT, death, or dropout). Results: Of 1289 included patients, 459 (35.6%) were women, and the mean (SD) age was 56.1 (10.0) years at assessment and listing. A total of 783 of 1289 listed patients underwent LT. Among those with no pLD at assessment, there was a higher median (range) Model for End-stage Liver Disease incorporating sodium levels (MELD-Na) score at listing (22 [6-50] vs 19 [6-50]; P < .001) and at LT (27 [6-49] vs 20 [6-52]; P < .001) in women receiving DDLT. Women were at a significant disadvantage without a pLD (hazard ratio [HR], 1.29; 95% CI, 1.04-1.60; P = .01); there was no difference in access to LT with availability of a pLD (HR, 0.93; 95% CI, 0.76,-1.14; P = .44). The instantaneous rate of receiving a transplant in men with a pLD was 1.39 times higher than men who did not have a pLD (HR, 1.39; 95% CI; P < .001) and the instantaneous rate of receiving a transplant in women with a pLD was 1.92 times higher than in women who did not (HR, 1.92; 95% CI, 1.51-2.44; P < .001). The HR was 1.38 times higher in women compared with men across the MELD-Na score strata (HR, 1.38; 95% CI, 1.03-1.84; P = .03) and 2.04 times higher when the MELD-Na score was less than 20 (HR, 2.04; 95% CI, 1.31-3.14; P = .001). Conclusions and Relevance: These study findings suggest that women can overcome the complex problem of allocation inequity with access to livers from living donors. Women with access only to DDLT were much more unwell than men independent of liver disease at the time of listing, dropout, or LT. Therefore, the wider availability of living donation liver transplant would be helpful in addressing the sex disparity in access to LT in the current MELD-Na era.

Management of Toddler's Fractures: A Systematic Review.

OBJECTIVES: The aim of this study was to examine and compare the efficacy of external fixation strategies of toddler's fracture (TF) in acute care settings. Specifically, we aim to identify whether immobilization optimizes clinical outcomes for patients (based on immobilization duration, time to weight-bear/ambulate, and associated complications) compared with nonimmobilization, with a systematic review. STUDY DESIGN: After PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines, 2 independent reviewers searched electronic databases OVID Medline, Embase, and CINAHL for studies evaluating the health outcomes of various treatment methods for TF (1937-2019). The studies were chosen based on specific inclusion criteria. The 2 reviewers were looking for primary research articles that assessed health outcomes (such as immobilization duration, time to weight-bear/ambulate, and associated complications) of various treatment strategies for TF Fractures in acute care settings. RESULTS: A total of 2385 articles were initially screened, reviewed, and then narrowed down to 6 studies for an in-depth analysis. Among these 6 studies, 5 were retrospective chart reviews and 1 was a cross-sectional online survey. A total of 565 patients from the retrospective chart reviews and 153 physicians from the cross-sectional online survey were further analyzed. The current evidence shows that there was no significant difference in clinical outcomes (ie, time to weight-bear and immobilization duration) between immobilization and nonimmobilization. CONCLUSIONS: Further large-scale prospective studies examining the clinical outcomes of TF management techniques should be conducted to establish a consistent standardized guideline for TF treatment across acute care settings.
