Various groups of chemicals that we encounter in every-day life are known to disrupt the endocrine system, such as estrogen mimics that can disturb normal cellular development and homeostasis. To understand the effect of estrogen on intracellular protein dynamics and how this relates to cell proliferation, we aimed to develop a quantitative description of transcription factor complexes and their regulation of cell cycle progression in response to estrogenic stimulation. We designed a mathematical model that describes the dynamics of three proteins, GREB1, PR and TFF1, that are transcriptionally activated upon binding of 17β-estradiol (E2) to estrogen receptor alpha (ERα).

Background/objectives: With growing survival rates for Adolescent and Young Adults (AYAs) diagnosed with gynecological cancer, the focus shifted to Quality of Life (QoL). Fertility-sparing surgery offers a viable alternative to standard, usually fertility-impairing treatments. Treatment choice remains difficult and renders perspectives of AYAs on decision-making and psychological outcomes afterwards.

Objectives: The World Health Organization supports both the screen-and-treat (ST) approach and the screen, triage and treat (STT) approach to cervical cancer screening using high-risk human papillomavirus (hrHPV) testing. For Uganda, the sequence of hrHPV-ST and hrHPV-STT could be similar, with visual inspection with acetic acid (VIA) after positive hrHPV tests in both. To consider potential tradeoffs (overtreatment in ST versus missed cancer cases in STT), we compared hrHPV-STT with VIA triage (STT-VIA), and STT with HPV 16/18 genotyping risk stratification, to hrHPV-ST for Uganda, in terms of overtreatment, cervical cancer incidence, and life years, for the general female population of Uganda.

Background: Uganda has a high burden of cervical cancer and its current coverage of screening based on visual inspection with acetic acid (VIA) is low. High-risk HPV (hrHPV) testing is recommended by the World Health Organization as part of the global elimination strategy for cervical cancer. In this context, country-specific health economic evaluations can inform national-level decisions regarding implementation.

Introduction: In Bangladesh, the uptake of cervical cancer screening is low. Lack of knowledge and understanding of symptoms and risk factors contributes to low screening uptake. The purpose of this study was to explore the knowledge of cervical cancer risk factors and symptoms and to measure the association with socio-demographic characteristics among women and household decisionmakers living in hard-to-reach areas of Bangladesh.
