Article Abstract
Radiotherapy is one of the most effective therapeutic strategies for cervical cancer patients, although radioresistance-mediated residual and recurrent tumors are the main cause of treatment failure. However, the mechanism of tumor radioresistance is still elusive. DNA damage response pathways are key determinants of radioresistance. The purpose of this study was to investigate the role and mechanism of SND1 in radioresistance of cervical cancer. A stable HeLa cell line with SND1 knockout (HeLa-KO) was generated through a modified CRISPR/Cas9 double-nicking gene editing system. The stable CaSki cell lines with SND1 knockdown (CaSki-Ctrl, CaSki-SND1-sh-1, CaSki-SND1-sh-2) were constructed through lentivirus transfection with the pSil-SND1-sh-1 and pSil-SND1-sh-2 plasmids. It was observed that SND1 deficiency significantly increased the radiosensitivity of cervical cancer cells. It was also found that silencing SND1 promotes radiation-induced apoptosis. Significantly, the cells with a loss of SND1 function exhibited inefficient ataxia telangiectasia mutated pathway activation, subsequently impairing DNA repair and G2/M checkpoint arrest. In addition, threonine 103 is an important phosphorylation site of SND1 under DNA damaging stress. Collectively, the results of this study reveal a potent radiosensitizing effect of silencing SND1 or T103 mutation on cervical cancer cells, providing novel insights into potential therapeutic strategies for cervical cancer treatment.

Hemostatic Efficacy of TachoSil in Loop Electrosurgical Excisional Procedure: A Prospective Randomized Controlled Study.
J Low Genit Tract Dis

Department of Obstetrics and Gynecology, University of Ulsan College of Medicine, Asan Medical Center, Seoul, Republic of Korea.
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).
