Background/aim: Cervical cancer is one of the leading causes of cancer death in women worldwide. BRM270 (BRMLife) has therapeutic potential for cancer treatment owing to its ability to inhibit cell proliferation, and expression of cluster of differentiation (CD) 133 in CD133 cancer cells. This study was designed to evaluate the therapeutic effects of plant extract formulation BRM270 against cervical cancer progression.
Materials And Methods: The expression of sex-determining region Y-box 2 (SOX2) was tested in four different cervical cancer cell lines, HeLA, SiHa, Caski and C33A. SOX2-expressing SiHa and C33A cell lines were selected for further experiments on the in vitro and in vivo effects of BRM270 on cervical cancer progression using western blotting, flow cytometry, sphere-formation assay, magnetic-activated cell sorting of CD133 cervical cancer cells, and xenografts in female athymic BALB/c nude mice.
Results: In the present study, in cervical cancer stem cells (CSCs), we found that BRM270 inhibited expression of SOX2, which is associated with cervical cancer initiation and metastasis. BRM270 also inhibited CD133 expression and induced apoptosis of CSCs and suppressed CD133 CSC proliferation and sphere formation in vitro as well as SiHa and C33A cell xenograft tumor growth in vivo. This was accompanied by down-regulation of markers of epithelial-to-mesenchymal transition.
Conclusion: BRM270 might be an effective agent for cervical cancer treatment.

Objective: The aim of the study was to evaluate the hemostatic efficacy of the fibrin sealant patch (TachoSil) after loop electrosurgical excision (LEEP) and its influence on other complications and quality of life (QoL).
Materials And Methods: This single-blind, prospective, randomized study involved patients undergoing LEEP with or without TachoSil (1:1) between August 2014 and August 2015 in Asan Medical Center, Korea. Primary outcome measures were bleeding duration and the frequency of additional treatment owing to vaginal bleeding within 2 weeks after LEEP.
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.

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).
