Background: Circular RNAs (circRNAs) have a vital role in the occurrence of numerous cancers. However, its function and pattern of expression in cervical cancer (CC) remain unclear. This research aims to investigate the hsa_circ_000002's regulatory mechanism in CC.
Methods: Hsa_circ_0000021, miR-3940-3p, and KPNA2 expression levels were estimated through qRT-PCR. Nuclear/cytoplasmic separation was conducted to find the subcellular location of hsa_circ_0000021. Western blot was done to estimate the levels of KPNA2 protein. CCK-8, BrdU, wound healing, transwell, and tumor xenograft assays were performed to study how hsa_circ_0000021/miR-3940-3P/KPNA2 function affect CC. Hsa_circ_0000021's targeting relationships with miR-3940-3p and KPNA2 were ascertained through RIP and luciferase experiments.
Results: Hsa_circ_0000021 and KPNA2 were overexpressed and inversely associated with the levels of miR-3940-3p in CC. Knocking down either hsa_circ_0000021 or KPNA2 repressed the growth of CC tumors as well as the proliferation, invasion, and migration of CC cells. Silencing miR-3940-3p promoted the malignant proliferation of CC cells. Regarding its mechanism, hsa_circ_0000021 affected the malignant CC cell proliferation via the sponging of miR-3940-3p, which targeted KPNA2.
Conclusion: Hsa_circ_0000021 regulates the miR-3940-3p/KPNA2 axis to promote CC occurrence. This potentially is a novel target for CC treatment.

Objectives: To assess the time taken to diagnose cervical cancer in Brazil and identify associated sociodemographic and clinical factors in the period 2016-2020.
Methods: This was a cross-sectional study of cervical neoplasms diagnosed between 2016 and 2020, using data collected from the Hospital Cancer Registry. The logistic regression model was applied to calculate odds ratios (OR) and 95% confidence intervals (95%CI).

In this article an analysis of the preventive campaigns against cervical cancer (CC) and human papillomavirus (HPV) vaccination developed by the National Cancer Institute (INCA) of the Ministry of Health was conducted, in addition to some campaigns produced by non-governmental organizations and private institutions, from 2014 to 2020. From a socio-anthropological point of view, the objective was to understand how these health technologies trigger and produce gender representations. Seven categories of analysis were developed ("Generationality of care", "Schooling", "Childhood and Youth", "Gamification", "Health risk", "Men's health" and "Neutrality") that permitted discussion of the themes that emerged in graphic pieces.

Background: While screening for cervical, colorectal, and lung cancers reduce cancer-specific mortality, the full benefits of screening are only realized when coupled with timely care across the subsequent "screening continuum" steps, including surveillance (results warranting frequent monitoring), diagnostic evaluation (results that require additional testing), and treatment (detected cancers). Our goal was to describe the proportion of individuals receiving timely cervical, colorectal, and lung cancer care at each step in the screening continuum.
Methods: This retrospective cohort study used data from the 10 health care settings that participate in the Population-based Research to Optimize the Screening Process (PROSPR II) consortium and included individuals who were eligible for a step along the cancer screening continuum in 2018.

To compare HPV vaccination knowledge and non-adherence rates to cervical cancer screening in a nationally representative sample of American women before and following the COVID-19 pandemic, female participants aged 21-65 years from the National Cancer Institute Health Information National Trends Survey 2019 and 2022 were included. Adherence to cervical cancer screening was assessed based on the timing of their last Papanicolaou (PAP) smear, with participants classified as non-adherent to cervical cancer guidelines if their last PAP smear was > 3 years. Further, participants were asked about their knowledge of the HPV vaccine and were categorized as unaware if they had not heard of it before.
