Article Abstract
Background And Objective: Cervical cancer is an important health problem in our country. It is known that there are several risk factors for this neoplasm, and it has been suggested that cervical microbiome alterations could play a role in the development and progress of cancer. Bacterial vaginosis associated bacteria such as Atopobium vaginae and Gardnerella vaginalis has been suggested as potential risk factor for cervical lesions and cervical cancer.
Material And Methods: DNA from 177 cervical scraping samples was studied: 104 belonged to women without cytological or colposcopic alterations and 73 samples from precursor lesions with previous human papillomavirus (HPV) infection history. All samples were screened for Atopobium vaginae, Gardnerella vaginalis and HPV by PCR.
Results: High HPV prevalence was found in precursor samples, and 30% of samples without lesions were positive for HPV. Virtually all samples contained sequences of both bacteria, and interestingly, there was not HPV association observed; these results could suggest that these microorganisms could be part of the cervical microbiome in Mexican population.
Conclusions: The results obtained indicate that the bacteria analysed could be part of normal biome in Mexican women, suggesting a potential reconsideration of the pathogen role of these microorganisms.
Background: Cervical cancer (CC) is a preventable noncommunicable disease if detected early through screening for precancers and appropriately managed. The causal link with high-risk human papillomavirus infection is established, making elimination possible through the WHO multipronged 90:70:90 strategy. However, practical CC elimination efforts need to address issues within the sociocultural context that can facilitate or hinder prevention strategies.
Introduction: High-resolution anoscopy (HRA) to prevent anal cancer is complex and screening capacity is limited. Previously, we showed that DNA methylation analysis of anal high-grade squamous intraepithelial lesions (HSIL) biopsies can distinguish between HSIL with an increased cancer risk, and HSIL with a low cancer risk, in which treatment may be safely withheld. Here, we assessed the performance of methylation analysis in anal swabs to identify patients with underlying HSIL with an increased cancer risk.

Background: Human papillomavirus (HPV) infection profoundly affects women living with HIV (WLWH). This infection leads to cervical cancer (CC) and increased mortality.
Methods: This study monitored HPV infection in WLWH in Rio de Janeiro, Brazil, before (T1) and after (T2) 4 years of vaccination.
Background: In the United States, human papillomavirus (HPV) vaccination among 27- to 45-y-olds (mid-adults) is recommended based on shared clinical decision making with a health care provider. We developed a patient decision aid tool to support the implementation of this mid-adult HPV vaccination guideline. The purpose of this study was to evaluate the effect of a patient decision aid tool for HPV vaccination, HPV DECIDE, compared with an information fact sheet among mid-adults who have not received the HPV vaccine.
Background: Uptake of human papillomavirus (HPV) vaccination is generally high in high-income countries with school-based vaccination programmes; however, lower uptake in certain population subgroups could continue pre-immunisation inequalities in cervical cancer.
Methods: Six electronic databases were searched for quantitative articles published between 1 September 2006 and 20 February 2023, which were representative of the general population, with individual-level data on routine school-based vaccination (with >50% coverage) and sociodemographic measures. Titles, abstracts and full-text articles were screened for eligibility criteria and assessed for bias.
