RESUMO

Human papillomavirus (HPV) is the most common sexually transmitted viral infection worldwide, which may result in the development in benign lesions or malignant tumors. The prevalence of HPV infection is twice as high in pregnancy as in non-pregnant women. Additionally, there is a risk of vertical transmission of HPV from mother to fetus during pregnancy or childbirth. Various studies have reported an increased risk of adverse pregnancy outcomes in HPV-positive women, including miscarriage, preterm birth, premature rupture of membranes, preeclampsia, fetal growth restriction, and fetal death. HPV vaccination is not currently recommended during pregnancy. On the other hand, there is no evidence linking HPV vaccination during pregnancy with adverse pregnancy outcomes and termination of pregnancy is not justified in this case.

RESUMO

Introduction: Gynecologists and pediatricians have an essential duty to prevent cervical cancer. In this study, we compared the compliance of gynecologists (n = 22) and pediatricians (n = 49) with nurse/midwife (n = 66) and non-medical moms (n = 120) with regards to cervical cancer precautions. Methods: A questionnaire was used to gather data on their demographics, personal vaccination and screening practices, children's immunization status, and awareness of cervical cancer prevention. Results: The findings demonstrated that gynecologists and pediatricians were better than others at understanding the risk factors and prevention of cervical cancer. It was noted that compared to other groups, physician mothers and their offspring had higher vaccination rates (n = 13, 18.3%; n = 10, 29.4%, respectively). Medical professionals typically provided thorough and accurate answers to informational questions. More frequent Pap smear tests were performed by gynecologists. It was noted that mothers who worked as pediatricians and nurses/midwives neglected their own screening needs. Discussion: This questionnaire survey sought to ascertain Istanbul's health professionals' present opinions regarding HPV vaccination. Healthcare professionals should be the first to receive information on HPV vaccination and cervical cancer incidence reduction. The public could then readily use them as an example.

RESUMO

PURPOSE: Disparities in cervical cancer screening, incidence, and mortality exist in the United States. Cervical cancer incidence and mortality rates in Texas are 20% and 32% higher, respectively, than national averages. Within Texas, these rates are significantly higher among non-Hispanic (NH) Black and Hispanic women. Cervical cancer screening uptake is lower among NH Black and Hispanic women (72.9% and 75.9%, respectively) compared with White women (85.5%) in Texas. METHODS: During March-August 2023, we conducted a pilot study that offered culturally competent education and human papillomavirus (HPV) self-sampling kits to women in two public housing projects in Houston, TX, that have predominantly NH Black or Hispanic residents. Among those eligible for cervical cancer screening, 35% (n = 24) of the NH Black and 34% (n = 16) of the Hispanic women were found to be underscreened per the US Preventive Services Task Force Guideline. We recruited 40 (24 NH Black and 16 Hispanic) eligible women for our study. The study was approved by the MD Anderson institutional review board and registered with ClinicalTrials.gov (NCT04614155-March 11, 2020). RESULTS: Seventy-five percent of the NH Black and 87% of the Hispanic participants completed the HPV self-sampling procedures per protocol. Samples of 17% NH Black and 12% Hispanic participants showed a performance error. Overall, cervical cancer screening uptake improved from 65% to 91% among NH Black and from 66% to 96% among Hispanic participants. CONCLUSION: Culturally competent education and HPV self-sampling resulted in remarkable improvement in cervical cancer screening uptake among underscreened NH Black and Hispanic women residents of Houston public housing projects. Implementing this strategy could significantly reduce cervical cancer incidence and mortality among similar populations in the United States and globally.

RESUMO

Methylation panels, tools for investigating epigenetic changes associated with diseases like cancer, can identify DNA methylation patterns indicative of disease, providing diagnostic or prognostic insights. However, the application of methylation panels focusing on the sex-determining region Y-box 1 (SOX1) and paired box gene 1 (PAX1) genes for diagnosing cervical lesions is under-researched. This study aims to examine the diagnostic performance of PAX1/SOX1 gene methylation as a marker for cervical precancerous lesions and its potential application in triage diagnosis. From September 2022 to April 2023, 181 patients with abnormal HPV-DNA tests or cytological exam results requiring colposcopy were studied at Hubei Maternal and Child Health Hospital, China. Data were collected from colposcopy, cytology, HPV-DNA tests, and PAX1/SOX1 methylation detection. Patients were categorized as control, cervical intraepithelial neoplasia Grade 1 (CIN1), Grade 2 (CIN2), Grade 3 (CIN3), and cervical cancer (CC) groups based on histopathology. We performed HPV testing, liquid-based cytology, and PAX1/SOX1 gene methylation testing. We evaluated the diagnostic value of methylation detection in cervical cancer using DNA methylation positivity rate, sensitivity, specificity, and area under the curve (AUC), and explored its potential for triage diagnosis. PAX1/SOX1 methylation positivity rates were: control 17.1%, CIN1 22.5%, CIN2 100.0%, CIN3 90.0%, and CC 100.0%. The AUC values for PAX1 gene methylation detection in diagnosing CIN1+, CIN2+, and CIN3+ were 0.52 (95% confidence interval [CI]: 0.43-0.62), 0.88 (95% CI: 0.80-0.97), and 0.88 (95% CI: 0.75-1.00), respectively. Corresponding AUC values for SOX1 gene methylation detection were 0.47 (95% CI: 0.40-0.58), 0.80 (95% CI: 0.68-0.93), and 0.92 (95% CI: 0.811-1.00), respectively. In HPV16/18-negative patients, methylation detection showed sensitivity of 32.4% and specificity of 83.7% for CIN1+. For CIN2+ and CIN3+, sensitivity was all 100%, with specificities of 83.0% and 81.1%. Among the patients who underwent colposcopy examination, 166 cases had cytological examination results ≤ASCUS, of which 37 cases were positive for methylation, and the colposcopy referral rate was 22.29%. PAX1/SOX1 gene methylation detection exhibits strong diagnostic efficacy for cervical precancerous lesions and holds significant value in triage diagnosis.

RESUMO

Human papillomavirus (HPV) genotyping is widely used, particularly in combination with high-risk (HR) HPV tests for cervical cancer screening. We developed a genotyping method using sequences of approximately 800 bp in the E6/E7 region obtained by PacBio single molecule real-time sequencing (SMRT) and evaluated its performance against MY09-11 L1 sequencing and after the APTIMA HPV genotyping assay. The levels of concordance of PacBio E6/E7 SMRT sequencing with MY09-11 L1 sequencing and APTIMA HPV genotyping were 100% and 90.8%, respectively. The sensitivity of PacBio E6/EA7 SMRT was slightly greater than that of L1 sequencing and, as expected, lower than that of HR-HPV tests. In the context of cervical cancer screening, PacBio E6/E7 SMRT is then best used after a positive HPV test. PacBio E6/E7 SMRT genotyping is an attractive alternative for HR and LR-HPV genotyping of clinical samples. PacBio SMRT sequencing provides unbiased genotyping and can detect multiple HPV infections and haplotypes within a genotype.

RESUMO

One of the most prevalent malignancies in women is cervical cancer. Cervical cancer is mostly brought on by chronic high-risk human papillomavirus 16 (HPV16) and HPV18 infection. Currently, the widely used HPV vaccines are the bivalent Cervarix, the tetravalent Gardasil, and the 9-valent Gardasil-9.There are differences in T cell effector molecule changes, B cell antibody level, duration, age and the injection after vaccination of the three vaccines.

RESUMO

BACKGROUND: To determine the prevalence of HR-HPV in a series of lip SCC from South African patients, using currently accepted HPV-testing methodologies and to define the clinical and histomorphologic features of HPV-associated lip SCC. METHODS: Fifty SCC of lip and 50 control cases were tested for HR-HPV using p16 and HR-HPV DNA PCR. p16-equivocal/positive and HPV DNA PCR-positive SCC were further evaluated for the expression of HPV-16 and HPV-18 mRNA transcripts using reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) to confirm transcriptionally active HPV. RESULTS: p16 was positive in 22% (n = 11) and equivocal in 4% (n = 2) of the SCC. One p16-positive case showed positivity for both HPV-16 DNA and HPV-16 E6/E7 mRNA transcripts (HPV prevalence rate of 2%). The HPV-positive case was non-keratinizing and occurred in an 80-year-old female. The two p16-equivocal cases were HR-HPV DNA positive and mRNA PCR negative. p16 was found to have a positive predictive value of 9%. CONCLUSION: Findings from our cohort of lip SCC suggest that HR-HPV may have an insignificant role in the pathogenesis of SCC at this site. Due to its low ppv, p16 is insufficient to establish HR-HPV infection in SCC of the lip. The combination of p16 and DNA PCR appears to correlate with the presence of transcriptionally active virus. HPV E6/E7 mRNA detection is the gold standard for identifying HR-HPV. mRNA testing is not widely available in sub-Saharan Africa due to technical and financial constraints; however, the test appears to be of great value in p16-equivocal lip SCC.

RESUMO

The implementation of Human Papillomavirus (HPV) vaccination is crucial for eliminating cervical cancer in India. The infodemic, characterised by misleading information, could hinder the successful implementation of the initiative. Misinformation related to the HPV vaccine, such as rumours, has been reported and circulated, contributing to an alarming pattern of vaccine hesitancy observed on social media. This study aimed to identify the public sentiment towards HPV vaccination based on the 'Behavioral and Social Drivers (BeSD)' framework through geospatial, content and sentiment analysis. A total of 1,487 tweets were extracted. After preprocessing, 1010 tweets were identified for sentiment and content analysis. The sentiments expressed towards the HPV vaccine are mixed, with a generally positive outlook on the vaccines. Within the population, there is a pervasive proliferation of misinformation, primarily focusing on vaccine safety and efficacy, contentious subjects, ethical considerations, and a prevalent sense of uncertainty in selecting the appropriate vaccine. These observations are crucial for developing targeted strategies to address public concerns and enhance vaccination rates. The insights gained from these results will guide policymakers, healthcare practitioners, and public health organisations to implement evidence-based interventions, thereby countering vaccine hesitancy and improving public health outcomes.

RESUMO

BACKGROUND:  Infection with the human papillomavirus (HPV) is a necessary cause of cervical cancer and is one of the most prevalent sexually transmitted infections worldwide. Primary prevention strategies target reducing HPV acquisition through vaccination, limiting exposure (e.g. delayed sexual debut, barrier contraception) and health education focusing on sexual behaviour and tobacco use. METHODS:  The ImmunoVACCS study, conducted from 2019 to 2022 in two provinces in South Africa, examined sociodemographic characteristics, sexual practices, and knowledge of cervical cancer and the HPV vaccine among young female vaccine recipients. It encompassed participants from the previously conducted vaccine implementation trials, VACCS 1 and VACCS 2 (2011-2014). Recruitment involved telephonic contact with eligible potential participants. Data were collected through self-administered questionnaires. RESULTS:  One hundred and eleven participants took part in the current study (median age: 20 years; age range: 16-22 years). Most sexually active participants had their first engagement in secondary school (96.2%), and 77.2% used contraception during their last sexual activity. Knowledge gaps were evident, with only 13.5% recognising cervical cancer's cervix origin and 3.6% attributing it to a virus. Despite this, 70.3% had heard of a vaccine for cervical cancer. Less than half knew about the importance of regular Pap smears (49.5%), vaccine protection (44.1%) or condom use (20.7%) against HPV and cervical cancer. CONCLUSION:  The current study demonstrates that young women still lack complete information on cervical cancer and its risk factors even after receiving health education linked with vaccination.Contribution: This study underscores the necessity of ongoing education about HPV, its risks and preventive measures among young women to combat cervical cancer.

RESUMO

OBJECTIVE: The fight against cervical cancer requires effective screening together with optimal and on-time treatment along the care continuum. We examined the impact of cervical cancer testing and treatment guidelines on testing practices, and follow-up adherence to guidelines. METHODS: Data from Estonian electronic health records and healthcare provision claims for 50,702 women was used. The annual rates of PAP tests, HPV tests and colposcopies during two guideline periods (2nd version 2012-2014 vs 3rd version 2016-2019) were compared. To assess the adherence to guidelines, the subjects were classified as adherent, over- or undertested based on the timing of the appropriate follow-up test. RESULTS: The number of PAP tests decreased and HPV tests increased during the 3rd guideline period (p < 0.01). During the 3rd guideline period, among 21-29-year-old women, the adherence to guidelines ranged from 38.7% (44.4…50.1) for ASC-US to 73.4% (62.6…84.3) for HSIL and among 30-59-year-old from 49.0% (45.9…52.2) for ASC-US to 65.7% (58.8…72.7) for ASCH. The highest rate of undertested women was for ASC-US (21-29y: 25.7%; 30-59y: 21.9%). The rates of over-tested women remained below 12% for all cervical pathologies observed. There were 55.2% (95% CI 49.7…60.8) of 21-24-year-olds and 57.1% (95% CI 53.6…60.6) of 25-29-year-old women who received HPV test not adherent to guidelines. CONCLUSIONS: Our findings highlighted some shortcomings in guideline adherence, especially among women under 30. The insights gained from this study help to improve the quality of care and, thus, reduce cervical cancer incidence and mortality.

RESUMO

HPV vaccination coverage remains far below the national target of 80% among US adolescents, particularly in rural areas, which have vaccine uptake rates that are 10% points lower than non-rural areas on average. Primary care professionals (PCPs) can increase coverage by using presumptive recommendations to introduce HPV vaccination in a way that assumes parents want to vaccinate. Through semi-structured interviews, we explored PCPs' experiences and perceptions of using presumptive recommendations in rural- and non-rural-serving primary care clinics in North Carolina. Thematic analysis revealed that most PCPs in rural and non-rural contexts used presumptive recommendations and felt the strategy was an effective and concise way to introduce the topic of HPV vaccination to parents. At the same time, some PCPs raised concerns about presumptive recommendations potentially straining relationships with certain parents, including those who had previously declined HPV vaccine or who distrust medical authority due to their past experiences with the healthcare system. PCPs dealt with these challenges by using a more open-ended approach when introducing HPV vaccination to parents. In conclusion, our findings suggest that PCPs in both rural and non-rural settings see value in using presumptive recommendations to introduce HPV vaccination, but to adequately address concerns and ensure increased HPV vaccine uptake, PCPs can use simple and culturally sensitive language to ensure fully informed consent and to maintain parental trust. And to further strengthen HPV vaccine discussions, PCPs can utilize other effective HPV communication techniques, like the Announcement Approach, in discussing HPV vaccinations with hesitant parents.

RESUMO

Head and Neck Squamous Cell Carcinoma (HNSCC) comprises a diverse group of tumors with variable treatment response and prognosis. The tumor microenvironment (TME), which includes microbiome and immune cells, can impact outcomes. Here, we sought to relate the presence of specific microbes, gene expression, and tumor immune infiltration using tumor transcriptomics from The Cancer Genome Atlas (TCGA) and associate these with overall survival (OS). RNA sequencing (RNAseq) from HNSCC tumors in TCGA was processed through the exogenous sequences in tumors and immune cells (exotic) pipeline to identify and quantify low-abundance microbes. The detection of the Papillomaviridae family of viruses assessed HPV status. All statistical analyses were performed using R. A total of 499 RNAseq samples from TCGA were analyzed. HPV was detected in 111 samples (22%), most commonly Alphapapillomavirus 9 (90.1%). The presence of Alphapapillomavirus 9 was associated with improved OS [HR = 0.60 (95%CI: 0.40-0.89, p = .01)]. Among other microbes, Yersinia pseudotuberculosis was associated with the worst survival (HR = 3.88; p = .008), while Pseudomonas viridiflava had the best survival (HR = 0.05; p = .036). Microbial species found more abundant in HPV- tumors included several gram-negative anaerobes. HPV- tumors had a significantly higher abundance of M0 (p < .001) and M2 macrophages (p = .035), while HPV+ tumors had more T regulatory cells (p < .001) and CD8+ T-cells (p < .001). We identified microbes in HNSCC tumor samples significantly associated with survival. A greater abundance of certain anaerobic microbes was seen in HPV tumors and pro-tumorigenic macrophages. These findings suggest that TME can be used to predict patient outcomes and may help identify mechanisms of resistance to systemic therapies.

RESUMO

The main aim of our study was to investigate the specific contribution of a 9-valent human papillomavirus vaccine (9vHPV) to the recurrence risk of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) in women vaccinated post-excision. Therefore, we conducted a retrospective monocentric cohort study in women aged 22-49 years undergoing conization between 2014 and 2023. The 9vHPV-vaccinated women were matched to unvaccinated women for age and follow-up duration in a 1:2 ratio to eliminate allocation bias. The risk of CIN2+ recurrence was estimated by the incidence rate ratio using Poisson regression with adjustment for comorbidities, smoking status, nulliparity, CIN grade, positive cone margin, and HPV genotypes. The CIN2+ recurrence rates in 147 women enrolled in the analysis were 18 and 2 cases per 100,000 person-days for unvaccinated and vaccinated women, respectively, during a mean follow-up period of 30 months (±22 months). A reduction in CIN2+ recurrences by 90% (95% confidence interval: 12-99%) was documented in 9vHPV-vaccinated participants compared to women undergoing only surgical excision. Moreover, vaccinated women with a positive cone margin showed a 42% (though non-significant) reduction in relapse (p = .661). Full post-conization vaccination with the 9vHPV contributed to an additional reduction in the risk of CIN2+ recurrence. This finding is consistent with current knowledge and suggests a high adjuvant effect of the 9vHPV vaccine.

RESUMO

Cervical cancer has become a global public health problem that poses a serious threat to women's health. Human papillomavirus (HPV) vaccination is an important primary preventive measure for cervical cancer. With the accelerated application of the HPV vaccine in China, conducting real-world studies (RWS) on the application of HPV vaccines can guide the rational use of the vaccine, which is of great significance for the strategy and practice of accelerating the elimination of cervical cancer in China. The Yangtze River Delta Cervical Cancer and Female Lower Genital Tract Infection Prevention and Control Alliance and Yangtze River Delta Immunization Integration Working Group organized an expert group to develop the "Expert recommendation for real-world study on the application of HPV vaccine in the Yangtze River Delta region". Based on the current situation of medical informatization and HPV vaccination administration in China, as well as literature and cases from domestic and international studies, this study describes the data chain of HPV vaccination and evaluation, introduces the study design, study direction, database construction, data governance and statistical analysis of RWS, and provides expert recommendation on the problems in carrying out the practice of HPV vaccine RWS, aiming to guide the RWS of HPV vaccine application and promote the generation of real-world evidence (RWE) in China.

RESUMO

Human papillomavirus type 16 (HPV16) is the most common cause of cervical cancer, but most infections are transient with lesions not progressing to cancer. There is a lack of specific biomarkers for early cancer risk stratification. This study aimed to explore the intrahost HPV16 genomic variation in longitudinal samples from HPV16-infected women with different cervical lesion severity (normal, low-grade, and high-grade). The TaME-seq deep sequencing protocol was used to generate whole genome HPV16 sequences of 102 samples collected over time from 40 individuals. Single nucleotide variants (SNVs) and intrahost SNVs (iSNVs) were identified in the viral genomes. A majority of individuals had a unique set of SNVs and these SNVs were stable over time. Overall, the number of iSNVs and APOBEC3-induced iSNVs were significantly lower in high-grade relative to normal and low-grade samples. A significant increase in the number of APOBEC3-induced iSNVs over time was observed for normal samples when compared to high-grade. Our results indicates that the lower incidence of iSNVs and APOBEC3-induced iSNVs in high-grade lesions may have implications for novel biomarkers discoveries, potentially aiding early stratification of HPV-induced cervical precancerous lesions.

RESUMO

INTRODUCTION: Men who have sex with men (MSM), especially those living with HIV, are at an increased risk of anal cancer. The prevalence and incidence of its precursor, anal high-grade squamous intraepithelial lesions (HSILs), among MSM who started antiretroviral therapy during acute HIV acquisition are yet to be explored. METHODS: Participants in an acute HIV acquisition cohort in Bangkok, Thailand, who agreed to take part in this study, were enrolled. All participants were diagnosed and started antiretroviral therapy during acute HIV acquisition. Human papillomavirus (HPV) genotyping and high-resolution anoscopy, followed by anal biopsy as indicated, were done at baseline and 6-monthly visits. RESULTS: A total of 89 MSM and four transgender women were included in the analyses. Median age at enrolment was 26 years. Baseline prevalence of histologic anal HSIL was 11.8%. With a total of 147.0 person-years of follow-up, the incidence of initial histologic anal HSIL was 19.7 per 100 person-years. Factors associated with incident anal HSIL were anal HPV 16 (adjusted hazards ratio [aHR] 4.33, 95% CI 1.03-18.18), anal HPV 18/45 (aHR 6.82, 95% CI 1.57-29.51), other anal high-risk HPV (aHR 4.23, 95% CI 1.27-14.14), syphilis infection (aHR 4.67, 95% CI 1.10-19.90) and CD4 count <350 cells/mm3 (aHR 3.09, 95% CI 1.28-7.48). CONCLUSIONS: With antiretroviral therapy initiation during acute HIV acquisition, we found the prevalence of anal HSIL among cisgender men and transgender women who have sex with men to be similar to those without HIV. Subsequent anal HSIL incidence, although lower than that of those with chronic HIV acquisition, was still higher than that of those without HIV. Screening for and management of anal HSIL should be a crucial part of long-term HIV care for all MSM.

RESUMO

Human papilloma virus (HPV) is the most common sexually transmitted viral agent in the world and the most common cause of cervical cancer. HPV prevalence and genotype distribution vary by region and demographic data. In a province in the south of Turkey that constantly receives immigration, we aimed to determine the prevalence of high-risk HPV (HR-HPV) genotypes, evaluate the compatibility between cervical Pap smear cytology results patients and HR-HPVs, and make an up-to-date contribution to the elucidation of epidemiological data. In this single-centre study, a total of 12,641 women aged 18 and over were evaluated retrospectively from January 2019 to July 2022. HPV detection and genotyping were analysed by the PCR method. Bethesda scoring was used for Pap smear cytological evaluation. The overall prevalence of HR-HPV was 12.6% (12.7% in Turkish women, 11.2% in foreign women). Among the typed HPVs that were detected, HPV-16 (31%) was found first, followed by HPV-18 (8%). The prevalence of HR-HPV was higher in women with abnormal cytology (977/1762, 55.4%) than in women with normal cytology (620/10879, 5.7%) (p<0.001). Turkey doesn't yet have a national HPV immunisation program. We think that determining the specific regional frequency of other HR-HPVs separately will be useful in the follow-up of the natural course of the type-specific infection and in vaccine studies in the future.

RESUMO

This research paper evaluates the efficacy of co-testing in precluding cervical cancer, with a particular focus on distinguishable outcomes of the human papillomavirus (HPV) vs. cytology tests. A retrospective review of 5948 patients, who tested positive for high-risk HPV but showed negative cytologic findings, revealed that 15.006% tested positive in subsequent screenings. A comparative analysis of various commercial HPV tests highlighted the precision of mRNA-based HPV testing by Aptima (Hologic) in reducing the likelihood of false-negative cytology. The paper challenges the conviction that a negative cytology alone suffices advocating for a condensed testing interval in instances of positive HPV outcomes, thereby facilitating earlier intervention and optimal preventive care. These findings unveil an exigency for reconsidering preventive strategies based on test outcomes.
