Purpose: The aim of this study was to evaluate the current cervical cancer magnetic resonance-guided brachytherapy (MRgBT) process in the study institution and seek opportunities to improve efficiency and optimize quality of care.
Methods: Eight procedures were observed where the time, location, and activities performed by health care professionals were recorded using Lean method principles. Wastes, as defined within Lean methodology, were identified during the observation. Workflow was illustrated by process maps. Milestone activities were identified for final time analysis. Finally, the research team developed solutions by eliminating wastes in the workflow.
Results: The mean procedure time ± standard deviation was 8.2 ± 0.41 hours, including 1.9 ± 0.18 hours spent on Lean wastes (84% waiting, 16% transportation). The most inefficient high-level activity was MRI with 1.1 hours spent on waiting and transportation. The parallel processing solution yields a 2.3 hours' time saving in each case. The optimal solution recommends an integrated MRgBT suite and dedicated human resource, yields a 4.1 hours' time saving (50% increase in efficiency) in each case.
Conclusion: This was the first study to quantify the performance of an MRgBT process. This study can serve as a template for other brachytherapy process improvements.

Population-based age-period-cohort analysis of declining Human Papillomavirus prevalence.

Background: Most countries in the world have launched human papillomavirus (HPV) vaccination programmes and declining prevalences of HPV are reported. We aimed to disentangle the influences of calendar time, birth cohort and age by analysing HPV prevalences in the population-based cervical screening programme using age-period-cohort modelling.
Methods: All 836,314 primary HPV-based cervical screening tests from women aged 23-64 between 2014-2023 in the capital region of Sweden were identified in the Swedish National Cervical Screening Registry.
Association of mental health treatment receipt with cancer screening among US adults with a history of anxiety or depression.

Background: Low participation in cancer screening contributes to a disproportionate burden of cancer morbidity and mortality among adults with mental health (MH) disorders like depression and anxiety. It is unknown whether MH treatment affects screening participation in this population.
Methods: Using the 2019 and 2021 National Health Interview Survey, data from screening-eligible respondents with a history of depression or anxiety were analyzed.

Background: Cervical cancer poses a significant threat to women's health and encompasses various histological types, including squamous cell carcinoma (SCC), cervical adenocarcinoma (CA), and adenosquamous carcinoma. CA, in particular, presents a formidable challenge in clinical management due to its low early detection rate, pronounced aggressiveness, high recurrence rate, and mortality, compounded by the complexities associated with late-stage treatment. There is limited understanding of the similarities and differences in the pathogenesis mechanisms between CA and SCC, such as tumor heterogeneity and the tumor immune microenvironment (TME).

Department of Urology, Hasheminejad Kidney Center, Iran University of Medical Sciences, Tehran, Iran.
Background: Labial adhesion (LA) is a total or partial labial fusion mostly seen in pre-pubertal children and is rare in premenopausal and postmenopausal periods. This review aimed to evaluate risk factors for labial fusion and the recurrence rate following surgical intervention in postmenopausal women.
Methods: According to PRISMA guidelines, international databases including Embase, World Cat, Web of Science, Scopus, Dimension, Open Grey, Cochrane, Google Scholar, and also PubMed gateway for PMC and MEDLINE were searched.
