Background: The majority of the US population have poor knowledge of cancers related to human papillomavirus (HPV). Identifying best sources for communicating this information can guide strategies to promote HPV vaccination.

Objectives: To assess the relationship between sources of health information and individuals' knowledge of HPV-related cervical and oropharyngeal cancer.

Methods: This study conducts logistic regression on the most recent wave (2019) of the Health Information National Trends Survey. Dependent variables are indicators for self-reported awareness that HPV causes (a) cervical cancer and (b) oropharyngeal cancer. The primary indicator is a variable for different sources of health information: The Internet, professional sources, print materials, friends/family and never looked for health information.

Results: Being female, young, non-Hispanic White and having college education is associated with higher odds of knowing about HPV-related cervical cancer. Controlling for demographic factors, individuals using professionals and the Internet are more likely to know that HPV causes cervical cancer (aOR: 2.65, 95% CI: 1.66, 4.25; aOR: 2.47, 95% CI: 1.75, 3.50, respectively) compared to those who have never looked for health information. Similar results were found for HPV-related oropharyngeal cancer.

Conclusion: Findings provide implications for targeted messaging through effective channels to improve HPV vaccination uptake.

Both women and men are now confronted with the grave threat of cancers caused by the human papillomavirus (HPV). It is estimated that 80% of women may encounter HPV over their lives. In the preponderance of cases involving anal, head and neck, oral, oropharyngeal, penile, vaginal, vulvar, and cervical malignancies, high-risk HPV (HR-HPV) is the causative agent.

Risk of residual/recurrent cervical diseases in HPV-positive women post-conization depends on HPV integration status.

Infect Agent Cancer

College of Clinical Medicine for Obstetrics & Gynecology and Pediatrics, Fujian Medical University, Fuzhou, Fujian, 350001, China.

Background: It is crucial to identify post-operative patients with HPV infection who are at high risk for residual/recurrent disease. This study aimed to evaluate the association between HPV integration and clinical outcomes in HPV-positive women after cervical conization, as well as to identify HPV integration breakpoints.

Methods: This retrospective study analyzed data of 791 women who underwent cervical conization for cervical intraepithelial neoplasia grades 2-3 (CIN2-3) between September 2019 and September 2023, sourced from the Fujian and Hubei cervical lesion screening cohorts.

Prevalence of non-vaccine high-risk HPV cervical infections in vaccinated women: a systematic review and meta-analysis.

BMC Infect Dis

January 2025

Programa de Pós-graduação em Ciências Farmacêuticas, Escola de Farmácia, Universidade Federal de Ouro Preto, Ouro Preto, Minas Gerais, Brazil.

Background: Human Papillomavirus (HPV) is the most common sexually transmitted lower genital tract infection worldwide and the main etiological factor of cervical cancer (CC). Since 2006, vaccines have been implemented to reduce CC-related morbidity and mortality. This systematic review and meta-analysis aimed to evaluate the prevalence of cervical infections by non-vaccine high-risk HPV (HR-HPV) types in women vaccinated against types 16 and 18.

Interleukin-17: A pleiotropic cytokine implicated in inflammatory, infectious, and malignant disorders.

Cytokine Growth Factor Rev

IL-17A, referred to as IL-17, is the founding member of a family of pro-inflammatory cytokines, including IL-17B, IL-17C, IL-17D, IL-17E (or IL-25), and IL-17F, which act via receptors IL-17RA to IL-17RE, and elicit potent cellular responses that impact diverse diseases. IL-17's interactions with various cytokines include forming a heterodimer with IL-17F and being stimulated by IL-23's activation of Th17 cells, which can lead to inflammation and autoimmunity. IL-17 is implicated in infectious diseases and inflammatory disorders such as rheumatoid arthritis and psoriasis, promoting neutrophil recruitment and anti-bacterial immunity, but potentially exacerbating fungal and viral infections, revealing its dual role as protective and pathologic.

Background: The association between bacterial vaginosis (BV) and increased HIV acquisition risk may be related to concentrations of HIV-susceptible immune cells in the cervix.

Methods: Participants (31 with BV and 30 with normal microbiota) underwent cervical biopsy at a single visit. Immune cells were quantified and sorted using flow cytometry (N=55), localization assessed by immunofluorescence (N=16), and function determined by bulk RNA sequencing (RNA-seq) of live CD45+ cells (N=21).
