Neurokinin-1 receptor (NK1R) belongs to tachykinin receptor family. Recent studies have suggested that NK1R was upregulated in cancer tissues including breast cancer, glioma and melanoma. Furthermore, NK1R antagonists have been employed to exert anti-tumor effect and promote cancer cell apoptosis. However, the role of NK1R in cervical cancer remains largely unknown. In this study, we aimed to detect the expression of NK1R in cervical cancer and evaluate the anti-tumor effects of NK1R antagonist on cervical cancer cells. We found that NK1R was highly expressed in cervical cancer tissues than in adjacent normal cervical tissues. Furthermore, by using NK1R antagonist we demonstrated that NK1R antagonist inhibited the viability and induced the apoptosis of cervical cancer cells in a dose-dependent manner, and the mechanism may be related to the inhibition of ERK activation and the regulation of apoptosis proteins Bcl-2 and BAX. In conclusion, these findings suggest that NK1R plays an oncogenic role in cervical cancer and is a promising target for cervical cancer therapy.

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.
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).
