RESUMEN

Background: In this study, we characterized the HPV genotype distribution in a population of 489 adults already positive for HPV DNA. The study population was divided into two groups: 244 HIV-positive (HIV+) men who have sex with men (MSM) undergoing routine anal screening for sexually transmitted diseases (STDs) and 245 women undergoing routine cervical cancer screening. Acknowledging the fact that women and MSM represent two independent circles of sexual practices, which are-largely-exclusive of each other, we were interested in determining if particular genotypes of human papillomavirus (HPV) disproportionately predominate in one of these circles compared to the other. Results: HIV+ MSM are significantly more likely to be infected with multiple genotypes at a time, with an odds ratio (OR) of 9.30 (95% confidence interval [CI]: 3.91-22.1) and a p-value of <0.001. In addition, multivariable-adjusted logistic regression analysis showed that anal swab samples were significantly more likely to harbor lrHPV infections, with an OR of 6.67 (95% CI: 2.42-18.4) and a p-value of <0.001, in particular, HPV 6, with an OR of 8.92 (95% CI: 3.84-20.7) compared to cervical samples of screening women. Conclusion: Given the significant impact of recurrent anogenital warts (AGWs) on quality of life and the accompanying predisposition to invasive anal cancer, our data underscore the critical need for HPV vaccination. This includes expanding vaccination eligibility to include both boys and adults within high-risk populations.

RESUMEN

The persistent infection of high-risk human papillomavirus (HPV) and the progression of cervical cancer necessitate the involvement of microenvironmental immunity. As cervical lesions advance, there is an observed increase in the infiltration of type 2 (M2) macrophages. However, the precise mechanism driving this increased infiltration of M2 macrophages remains unclear. In this study, we investigated the role of exosomes in polarising M2 macrophages in cervical lesions associated with HPV E6. Through the analysis of bioinformatics data and clinical specimens, we discovered a positive correlation between HPV E6/E7 mRNA copy number and the level of M2 macrophage infiltration. Exosomes derived from HPV E6 overexpressed (HPV E6+) cervical squamous cell carcinoma (CESC) cells were found to induce the polarisation of macrophages towards M2 type. Specifically, miR-204-5p, enriched in HPV E6 + CESC exosomes, was transported into macrophages and triggered M2 macrophage polarisation by inhibiting JAK2. The clinical relevance of exosomal miR-204-5p in the progression of cervical lesions was validated through serum samples from 35 cases. Exosomal miR-204-5p emerges as a critical factor influencing M2 macrophage polarisation and is correlated with the severity of cervical lesions. Consequently, miR-204-5p could be used as a potential treatment and a candidate biomarker for cervical lesions.

RESUMEN

Objective: We report the management of recurrent respiratory papillomatosis (RRP) employing a protocol that includes both office-based (OB) and general anaesthesia (GA) procedures. Quality of life (QoL) outcomes in the OB cohort were compared to those obtained from an historical cohort treated only under GA. Methods: Patients affected by RRP from 2019 until 2023 ("new protocol") and from 2012 to 2019 ("historical protocol") were enrolled. In both groups the Derkay site score (DSS) was calculated. In patients adhering to the new protocol, questionnaires measuring QoL were prospectively administered (voice handicap hindex-10 [VHI-10] along with a specific questionnaire to measure the tolerance to the OB procedures). A cost analysis was also performed. Results: In all, 35 patients composed the new protocol cohort and 13 the historical. In the first group, patients underwent a median of 4 treatments. At 2 years, 68% of patients were treated exclusively in the office. Overall, for the new protocol, median DSS and VHI-10 after one year were both significantly lower than those at baseline [2 vs 4 and 3 vs 14, respectively; p < 0.001]. No differences were found between the new and the historical protocol cohorts considering DSS over time. Conclusions: Treatment of RRP may be conducted successfully in an office-based setting reducing healthcare costs.

RESUMEN

Objectives: The purpose of this research was to evaluate, in a tertiary care context, the effects of human papillomavirus (HPV) infection on the incidence and prognosis of oral malignancies. Methods: At a tertiary care hospital, 100 patients who received an oral cancer diagnosis between 2020 and 2022 were the subject of a retrospective analysis. Medical records were used to gather clinicopathological data, and histopathological specimens' molecular analyses were used to ascertain the HPV infection status. To assess the variations in overall and disease-free survival between HPV-positive [HPV+] and HPV-negative [HPV-] patients, survival analysis was done. Results: Of the oral malignancies that tested positive for HPV, 25% were caused by strains HPV-16 and HPV-18. Patients who tested positive for HPV had unique clinicopathological characteristics, such as a decreased prevalence of lymph node involvement, nonkeratinizing histology, and younger age at diagnosis. When compared to HPV- patients, HPV+ patients had substantially better overall survival (P = 0.032) and disease-free survival (P = 0.047) according to survival analysis. Conclusion: The incidence and prognosis of oral malignancies are significantly impacted by HPV infection, as demonstrated by current data. When compared to HPV- cancers, HPV+ tumors have different clinicopathological characteristics and improved survival rates. These findings have implications for therapy selection and prognostication, and they highlight the significance of HPV testing in the therapeutic management of oral malignancies. To understand the underlying molecular pathways and provide tailored therapeutics for oral malignancies that are HPV+, more research is required.

RESUMEN

High grade serous ovarian carcinoma (HGSOC) is the most common and aggressive ovarian malignancy. Accumulating evidence indicates that HGSOC may originate from human fallopian tube epithelial cells (FTECs), although the exact pathogen(s) and/or molecular mechanism underlying the malignant transformation of FTECs is unclear. Here we show that human papillomavirus (HPV), which could reach FTECs via retrograde menstruation or sperm-carrying, interacts with the yes-associated protein 1 (YAP1) to drive the malignant transformation of FTECs. HPV prevents FTECs from natural replicative and YAP1-induced senescence, thereby promoting YAP1-induced malignant transformation of FTECs. HPV also stimulates proliferation and drives metastasis of YAP1-transformed FTECs. YAP1, in turn, stimulates the expression of the putative HPV receptors and suppresses the innate immune system to facilitate HPV acquisition. These findings provide critical clues for developing new strategies to prevent and treat HGSOC.

RESUMEN

The study sought to systematically compare the expression of molecular markers in benign cutaneous lesions and squamous cell cervical carcinoma associated with HPV infection to better understand the pathophysiological mechanisms involved in HPV-related lesions and their progression to malignancy. We included 200 patients recruited from a gynecological clinic divided into two groups: 100 patients with positive HPV tests presenting with cutaneous lesions and 100 patients diagnosed with squamous cell cervical carcinoma and testing positive for HPV. The participants were selected to ensure diverse ethnic and demographic representation. The study utilized different statistical analyses, including Chi-square tests to assess associations between categorical variables and logistic regression to evaluate factors influencing lesion progression and compare marker expressions across different lesion types. The results indicated significant differences in the expression of specific molecular markers between cutaneous lesions and cervical carcinomas, highlighting distinct molecular pathways involved in HPV-related lesion development. Notably, markers such as p16, p53, and E-cadherin showed varying expression, suggesting their potential role in distinguishing between benign and malignant lesions. The findings emphasize the significance of molecular marker profiling in improving diagnostic and therapeutic strategies for HPV-related lesions. The differential expression of molecular markers can offer valuable insights into the pathogenesis of HPV-induced lesions and help develop targeted interventions to prevent malignant transformation. Further research is necessary to validate these markers in larger cohorts and diverse populations.

RESUMEN

INTRODUCTION: The goal of our research programme is to develop culturally appropriate patient-specific interventions for primary and secondary prevention of human papillomavirus (HPV)-related oropharyngeal cancer (OPC) among people living with HIV (PLWH); PLWH are at a higher risk for OPC than the general population and, as with many cancers, there are disparities in OPC health outcomes by race and ethnicity. Our study incorporates an anti-racist research framework that proposes considering racism as a foundational sociocultural system that causes ill health. We expand the framework to include biases due to gender, sexual orientation, HIV status and membership in other non-dominant groups. Our research programme focuses on HPV-related OPC among people living with PLWH, and on how intersecting identities may impact an individual's experience with oral health, obtaining regular and appropriate oral healthcare, knowledge and perceptions of oral HPV infection, risk factors for OPC and HPV vaccination. METHODS AND ANALYSIS: We will follow a grounded theory (GT) qualitative research methodology using focus group discussions (FGDs) to collect data. We will invite PLWH with intersecting identities to participate in one of 12-18 FGDs with 5-8 participants per group. Focus groups will be formed based on self-reported domains, including race, ethnicity, gender identity, sexual orientation and other identities that could impact oral health, such as smoking status, experience with homelessness or experience with drug use disorders. We do not know which aspects of intersecting identities are most salient to accessing oral healthcare. Using FGDs will allow us to gain this knowledge in a setting where participants can build on and reinforce shared understandings about oral healthcare. Following our GT methodology, analysis will occur concurrently with data collection, and emerging concepts or theories may result in changes to focus group guide questions. Initial focus group questions will be organised around our main objectives: (1) to identify individual, interpersonal and structural health equity factors that serve as barriers or facilitators to oral health status and care; (2) to explore knowledge and perceptions about causes, risk factors, prevention and screening for oral or OPC and (3) to elicit recommendations for improving access to regular and appropriate oral healthcare and suggestions on engaging PLWH from diverse identity groups in prevention interventions. ETHICS AND DISSEMINATION: All methods and procedures were approved by the University of California, San Francisco, Institutional Review Board (approval number: 23-39307) and are in accordance with the Declaration of Helsinki of 1975, as revised in 2000. Participants are required to provide informed consent. The results of this study will be presented at scholarly meetings and published in peer-reviewed journals. In addition, a lay summary of results will be created and distributed to our participants and community through our website and social media. TRIAL REGISTRATION NUMBER: NCT06055868.

RESUMEN

Background: Vaginal microbiota is involved in human papillomavirus (HPV) infection and cervical cancer (CC) progression, and the specific changes in vaginal microbial composition during this process remains uncertain. Objective: This study aimed to observe the changes in the specific composition of vaginal microorganisms in different cervical lesions and identify biomarkers at different stages of lesions. Methods: In this study we used the illumina high-throughput gene sequencing technology to determine the V4 region of 16SrRNA and observed the vaginal microbial composition in different cervical lesions. Results: The vaginal microbiota of patients with high-risk HPV infection and cervical lesions is significantly different from that of the normal population, but there is no significant difference in the richness of vaginal microbes. The diversity of vaginal species in CC patients is higher than that in high-risk HPV infection or CIN patients. The main manifestation is an increase in the diversity of vaginal microbes, a decrease in the relative abundance of cyanobacteria and Lactobacillus, and an increase in the relative abundance of dialister, peptonephila and other miscellaneous bacteria. There are characteristic vaginal biomarker in normal women, high risk HPV patients and CC patients. In detail, the biomarker in the normal group was varibaculum, the biomarker in the high-risk HPV group was saccharopolyspora, the biomarker of the CC group was the Proteobacteria, Corynebacterium, Coprococcus, Peptococcus and Ruminococcus. Conclusions: The study indicated that the compositions of vaginal microbes in different cervical lesions is different. The vaginal microbial composition has a certain diagnostic effect on healthy women, patients with high-risk HPV infection and cervical lesions. These microbes may serve as potential biomarkers for CC. It also provided an effective way for the treatment of HPV infections and cervical lesions.

RESUMEN

To mitigate the impact of personal and structural barriers hindering HPV vaccination in military women, multiple research studies have advocated for adding the HPV vaccine to the mandatory list for enlistees. Intervention Mapping (IM) is a systematic and stepwise theory-based approach that has been used to inform the development of health promotion interventions and implementation strategies in community and clinical settings at national, regional, and global levels. Development and evaluation of effective strategies and multi-level interventions using IM may increase the uptake of the HPV vaccine among military females who are at-risk of HPV infections and associated co-morbidities.

RESUMEN

INTRODUCTION: Several observational or retrospective studies have previously been conducted to explore the possible association between lung cancer and human papillomavirus (HPV) infection. However, there may be inconsistencies in the data and conclusions due to differences in study design and HPV testing methods. There are currently no studies that provide conclusive evidence to support the involvement of HPV in the occurrence and development of lung cancer. Therefore, the relationship between HPV and lung cancer remains controversial and uncertain. This study aimed to explore whether HPV infection is causally related to lung cancer risk by systematically performing a two-way Two-Sample Mendelian Randomization (TSMR) analysis. METHODS: In the International Lung Cancer Consortium (ILCCO) genome-wide association study dataset, we included 11,348 lung cancer (LUCA) cases, including 3275 squamous cell carcinoma (LUSC) cases, 3442 adenocarcinoma (LUAD) cases, and 15,861 cases of control. Using genetic variants associated with the HPV E7 protein as instrumental variables, we summarized statistics associated with HPV infection in the MRC IEU OpenGWAS database, which included the HPV-16 E7 protein and the HPV-18 E7 protein. Two-sample Mendelian randomization (MR) results are expressed as odds ratios (OR) and 95% confidence intervals (CI). RESULTS: Based on a comprehensive analysis of genome-wide association study (GWAS) data from public databases, we mainly used inverse-variance weighted (IVW) to estimate causal relationships, while using MR-Egger, weighted median, simple mode, and weighted mode, and other four methods as supplements. Two-sample MR Analysis revealed no causal relationship between exposure factors (HPV-16 E7 protein and HPV-18 E7 protein) and outcome factors (lung cancer (LUCA) and its subtypes squamous cell carcinoma (LUSC) and adenocarcinoma (LUAD)) in forward MR Analysis using the IVW approach.HPV-16 E7 protein and LUCA and its subtypes LUSC and LUAD by IVW method results: [OR] = 1.002; 95% [CI]: 0.961 - 1.045; p = 0.920; [OR] = 1.023; 95% [CI]: 0.966 - 1.084; p = 0.438; [OR] = 0.994; 95% [CI]: 0.927 - 1.066; p = 0.872); HPV-18 E7 protein and LUCA and its subtypes LUSC and LUAD by IVW method results: [OR] = 0.965; 95% [CI]: 0.914 - 1.019; p = 0.197; [OR] = 0.933; 95% [CI]: 0.834 - 1.043; p = 0.222; [OR] = 1.028; 95% [CI]: 0.945 - 1.118; p = 0.524. It was observed through reverse MR that LUCA and its subtypes LUSC and LUAD were used as exposure factors, and HPV infection (HPV-16 E7 protein and HPV-18 E7 protein) was used as the outcome factors, the results of the IVW method are also invalid.LUCA and HPV-16 E7 protein and HPV-18 E7 protein by IVW method results: [OR] = 1.036; 95% [CI]: 0.761 - 1.411; p = 0.82; [OR] = 1.318; 95% [CI]: 0.949 - 1.830; p = 0.099; LUSC and HPV-16 E7 protein and HPV-18 E7 protein by IVW method results: [OR] = 1.123; 95% [CI]0.847 - 1.489; p = 0.421; [OR] = 0.931; 95% [CI]: 0.660 - 1.313; p = 0.682; LUAD and HPV-16 E7 protein and HPV-18 E7 protein by IVW method results: [OR] = 1.182; 95% [CI] 0.983 - 1.421; p = 0.075; [OR] = 1.017; 95% [CI]: 0.817 - 1.267; p = 0.877.Our results indicate that there is no causal relationship between genetically predicted HPV infection and LUCA and its subtypes LUSC and LUAD. In addition, in the reverse MR analysis, we did not observe a significant causal relationship between LUCA and its subtypes LUSC and LUAD on HPV infection. CONCLUSIONS: Our findings do not support a genetic association between HPV infection and lung cancer.

RESUMEN

It is now established that patients with rheumatoid arthritis (RA) have an increased risk of developing cervical cancer (CC) or its precursor, cervical intraepithelial neoplasia (CIN). However, the underlying mechanisms of this association have not been elucidated. RA is characterized by unresolved chronic inflammation. It is suggested that human papillomavirus (HPV) infection in RA patients exacerbates inflammation, increasing the risk of CC. The tumor microenvironment in RA patients with CC is also marked by chronic inflammation, which aggravates the manifestations of both conditions. Gut and vaginal dysbiosis are also considered potential mechanisms that contribute to the chronic inflammation and aggravation of RA and CC manifestations. Numerous clinical and pre-clinical studies have demonstrated the beneficial effects of various nutritional approaches to attenuate chronic inflammation, including polyunsaturated fatty acids and their derivatives, specialized pro-resolving mediators (SPMs), probiotics, prebiotics, and certain diets. We believe that successful resolution of chronic inflammation and correction of dysbiosis, in combination with current anti-RA and anti-CC therapies, is a promising therapeutic approach for RA and CC. This approach could also reduce the risk of CC development in HPV-infected RA patients.

RESUMEN

BACKGROUND: Human papillomavirus (HPV) infection has become an important etiological driver of oropharyngeal squamous cell carcinoma (OPSCC), leading to unique tumor characteristics. However, the interplay between HPV-associated tumor cells and tumor microenvironment (TME) remains an enigma. METHODS: We performed a single-cell RNA-sequencing (scRNA-seq) on HPV-positive (HPV+) and HPV-negative (HPV‒) OPSCC tumors, each for three samples, and one normal tonsil tissue. Ex vivo validation assays including immunofluorescence staining, cell line co-culture, and flow cytometry analysis were used to test specific subtypes of HPV+ tumor cells and their communications with T cells. RESULTS: Through a comprehensive single-cell transcriptome analysis, we uncover the distinct transcriptional signatures between HPV+ and HPV‒ OPSCC. Specifically, HPV+ OPSCC tumor cells manifest an enhanced interferon response and elevated expression of the major histocompatibility complex II (MHC-II), potentially bolstering tumor recognition and immune response. Furthermore, we identify a CXCL13+CD4+ T cell subset that exhibits dual features of both follicular and pro-inflammatory helper T cells. Noteworthily, HPV+ OPSCC tumor cells embrace extensive intercellular communications with CXCL13+CD4+ T cells. Interaction with HPV+ OPSCC tumor cells amplifies CXCL13 and IFNγ release in CD4+T cells, fostering a pro-inflammatory TME. Additionally, HPV+ tumor cells expressing high MHC-II and CXCL13+CD4+ T cell prevalence are indicative of favorable overall survival rates in OPSCC patients. CONCLUSIONS: Together, our study underscores a synergistic inflammatory immune response orchestrated by highly immunogenic tumor cells and CXCL13+CD4+ T cells in HPV+ OPSCC, offering useful insights into strategy development for patient stratification and effective immunotherapy in OPSCC.

RESUMEN

Introduction: Electroconization of the uterine cervix (LEEP/LLETZ) is an appropriate and sufficient procedure for high-grade squamous epithelial lesion - HSIL. Negative margins are considered fundamental for confirming the absence of residual disease. Further management after incomplete excision among women who have not completed their procreative plans is difficult because subsequent cervical procedures may cause issues with carrying a pregnancy to term. Since almost one-third of the untreated patients with HSIL will develop cervical carcinoma, it is essential to balance the desire to radicalize treatment with its obstetric consequences. We compared the further clinical course of the patients after complete and incomplete procedures to observe whether completeness of excision is necessary for a successful outcome. We aim to identify risk factors that influence persistent or recurrent HSIL. Methods: The study has comprised 781 patients aged 18-85 - the research group was composed of 140 (17.93%) patients after incomplete conization and the control group of 641 (82.17%) patients after the complete one. Patients were scheduled for follow-up examinations every 6 months - including cytology, HPV typing, and colposcopy with tissue sampling. The Chi-square test or Fisher's exact test was performed as a tool for group comparisons for variables on the qualitative scale. Univariable and multivariable logistic regression models have been used to determine factors associated with the risk of persistent or recurrent HSIL. To evaluate the discriminatory ability of the logistic regression models, the Area Under the Curve (AUC) was calculated. Results: The statistical analysis results don't indicate a statistical significance between the frequency of HSIL in groups. HPV infection has increased the risk of persistent/recurrent lesions by 38 times, constituting the most important factor. Discussion: Close follow-up instead of inconsiderate repeat procedures should be taken under consideration among patients of reproductive age after incomplete conization of the cervix. HPV typing may be an essential method to predict recurrent cervical dysplasia. Promoting HPV typing and vaccination can reduce the number of invasive procedures and improve quality of life and obstetrics outcomes.

RESUMEN

BACKGROUND: Human Papilloma Virus (HPV) infection is a significant public health concern in the Gulf Cooperation Council countries, being widely prevalent and the main risk factor for cervical cancer. We aimed to assess knowledge and perception towards HPV, acceptability of the HPV vaccine, and HPV vaccination rates among university students in Education City, Doha, Qatar. METHODS: This cross-sectional survey utilized proportional quota-sampling, with quotas based on university, sex, and nationality, to recruit students from seven universities between February and September 2022. The English language questionnaire requested socio-demographic information, knowledge, and attitudes about HPV infection and the vaccine. The chi-square test, Student t-test, Mann-Whitney-Wilcoxon tests and multivariable ordinal logistic regression were used to assess differences in proportion, mean, and median according to broad HPV knowledge categories. RESULTS: Three hundred and ninety-eight students were recruited (response rate = 82.3%), of whom 251 (63.1%) were female. Mean age was 21.7 years. Eighty-nine (22.4%, 95% CI 18.4-26.8%) students had poor knowledge about HPV, 220 (55.3%, 95% CI 50.2-60.2%) students had some awareness, and 89 (22.4%, 95% CI 18.4-26.8%) students were knowledgeable. Age, nationality, and field of study influenced the students' knowledge about HPV. Only 25 (6.3%) students had previously been vaccinated against HPV. However, 71% of the unvaccinated students reported being willing to get vaccinated if recommended by their healthcare provider. CONCLUSIONS: Overall, 77.7% of the student population had some-to-good levels of knowledge about HPV-related infection, cancer, and vaccination. There are gaps in the student population's understanding and knowledge about HPV. Increasing knowledge can be key toward shared decision-making for HPV vaccination among eligible populations. Targeted public health campaigns and integration into childhood vaccination programs should be critical first steps, especially as most of the surveyed students had a positive outlook on getting vaccinated. Healthcare professionals should be incentivized to increase their HPV knowledge and communication skills, while policymakers can work toward easing barriers in integrating HPV vaccinations in the immunization schedule and encouraging overall HPV vaccination uptake.

RESUMEN

BACKGROUND: The COVID-19 pandemic has underscored the critical role of sequencing technology in disease control and outbreak response. However, resource limitations and challenging environments often impede such efforts in low and middle-income countries. This study aimed to investigate the spectrum of viral co-infections, particularly with human viral pathogens, in SARS-CoV-2 positive individuals in Sierra Leone using metagenomic sequencing, evaluating the feasibility of utilizing this technology for epidemiological and evolutionary surveillance of pathogens related to public health in low-income environments. METHODS: We retrospectively collected and analyzed 98 nasopharyngeal swab specimens from SARS-CoV-2 positive individuals in Sierra Leone. Samples were pre-processed locally and transferred to China via FTA cards for metagenomic sequencing, which was performed using the Novaseq platform. The study focused on the identification of nasopharyngeal viruses co-infecting with SARS-CoV-2, with a deeper analysis of significant human viral pathogens such as HPV. RESULTS: The study identified 22 viral taxa from 20 families, including 4 human viruses. Notably, 19.4% of samples showed HPV co-infection with 34 distinct types, predominantly beta and gamma HPVs. Multiple HPV types were found in individual samples, indicating a high complexity of viral co-infections. CONCLUSIONS: The identification of a wide range of co-infecting viruses, particularly multiple HPV genotypes, highlights the complexity of viral interactions and their potential implications for public health. These findings enhance our understanding of viral co-infections and provide valuable insights for public health interventions in Sierra Leone. Further research is needed to explore the clinical significance of these findings and their impact on disease outcomes.

RESUMEN

Lacking of adequate knowledge is an obstacle to effective prevention of cervical cancer, yet factors that affect the information acquisition and seeking behavior as well as the information communication process are not well studied. We assessed information acquisition and seeking behavior, as well as perceived barriers of doctor-patient communication regarding human papilloma virus (HPV)-related information of infected women. Among 437 participants, 405 (93%) expressed demands for HPV-related information, while only a small proportion (100/437, 22.9%) actively sought information and felt obstacles comprehending. Web-based channels were most frequently utilized and medical personnel were the most trusted information source. Patients' satisfaction was significantly correlated with doctor's patience (r = 0.581, p < 0.001) and emotional caring (r = 0.555, p < 0.001). Compared to patients not actively seeking information, those actively seeking information were more likely to be single (p = 0.005), had higher education (p = 0.009) and monthly individual-level income (p = 0.023), and was more likely to undergo regular cervical cancer screening (p = 0.003), and were already or willing to be vaccinated (p = 0.008). The actively seeking information group also achieved higher scores in HPV knowledge test (p = 0.007). Public health interventions targeting HPV-infected women using specifically designed educational materials may influence information seeking behavior, increase HPV literacy and knowledge, which could potentially increase HPV vaccine uptake and cervical cancer screening rate.

RESUMEN

Objectives To evaluate the knowledge and awareness about cervical cancer and human papillomavirus (HPV) vaccination among medical undergraduates at Northern Border University. Methods It was a cross-sectional study done on students selected conveniently from the College of Medicine, Northern Border University, Arar. The data were collected regarding knowledge about HPV infection and vaccine awareness using a validated questionnaire. Results A total of 200 students responded to the questionnaires, with 104 (52%) being male students and 120 (60%) being clinical years of MBBS. The mean knowledge score was 17.12 ± 2.73 out of 24, which was labeled as moderate knowledge about cervical cancer and HPV. Almost two-thirds of the students responded correctly to the etiology and risk factors of cervical cancer, while only half of the students knew the correct screening intervals for cervical cancer. The awareness of students about the HPV vaccine was deficient, and the mean score was estimated to be 4.20 ± 0.79 out of nine. Female students and students in clinical years showed significantly better understanding and awareness about cervical cancer and its vaccine and showed greater vaccine acceptability as compared to male students and students in preclinical years. Conclusion The present study shows moderate knowledge about cervical cancer but deficient awareness of medical students about the HPV vaccine. However, the students were willing to get educated about cervical cancer and its vaccine and showed a favorable opinion towards vaccinating the schoolgirls and educating their patients as future physicians. The information can be considered a benchmark on knowledge and awareness levels and can be utilized to modify medical curricula and develop efficient awareness programs.

RESUMEN

Head and neck cancer (HNC) represents a significant global health challenge, with squamous cell carcinomas (SCCs) accounting for approximately 90% of all HNC cases. These malignancies, collectively referred to as head and neck squamous cell carcinoma (HNSCC), originate from the mucosal epithelium lining the larynx, pharynx, and oral cavity. The primary risk factors associated with HNSCC in economically disadvantaged nations have been chronic alcohol consumption and tobacco use. However, in more affluent countries, the landscape of HNSCC has shifted with the identification of human papillomavirus (HPV) infection, particularly HPV-16, as a major risk factor, especially among nonsmokers. Understanding the evolving risk factors and the distinct biological behaviors of HPV-positive and HPV-negative HNSCC is critical for developing targeted treatment strategies and improving patient outcomes in this complex and diverse group of cancers. Accurate diagnosis of HPV-positive HNSCC is essential for developing a comprehensive model that integrates the molecular characteristics, immune microenvironment, and clinical outcomes. The aim of this comprehensive review was to summarize the current knowledge and advances in the identification of DNA, RNA, and protein biomarkers in bodily fluids and tissues that have introduced new possibilities for minimally or non-invasive cancer diagnosis, monitoring, and assessment of therapeutic responses.

RESUMEN

AIM: To review the status of human papillomavirus (HPV) vaccination in Japan from inception to the present, focusing on past and current challenges. METHODS: Published articles and website content related to HPV vaccination were reviewed. RESULTS: The Ministry of Health, Labor and Welfare suspended proactive recommendations for HPV vaccination in June 2013 following repeated media reports of girls experiencing adverse events, including chronic pain and walking disturbances, after receiving the HPV vaccine. Despite later recognition of these symptoms as a functional somatic syndrome, HPV vaccine coverage of target girls aged 12 to 16 years in the National Immunization Program (NIP) rapidly decreased to near zero. This suspension of the proactive HPV vaccination recommendation ceased in fiscal year (f-year) 2022, initiating a 3-year catch-up free HPV vaccination period from April 2022 to March 2025 for women born from f-years 1997 to 2005. These drastic changes were driven by established evidence of the effectiveness and safety of HPV vaccines reported from both Japan and other countries, and a nine-valent HPV vaccine has been included in the NIP since f-year 2023. However, the estimated HPV vaccination rate in the NIP remains low at ≤30%. CONCLUSIONS: To regain high coverage of HPV vaccination in Japan, it is essential that government, industry, and academic society work together to raise awareness and educate Japanese people about cervical cancer prevention and HPV-related diseases.

RESUMEN

Human papillomavirus (HPV), a common sexually transmitted infection, has prompted the development of vaccines to mitigate associated cancer risks, particularly cervical cancer. Regions that have achieved a high rate of vaccination coverage are witnessing a transformative impact on public health, with a notable reduction of up to 30% in the incidence of cervical cancer cases. Emphasizing the broader impact of vaccination on public health, this review investigates the role of a school-entry mandate for the HPV vaccine, aiming to inform decisions about its potential benefits and challenges. With a focus on understanding the significance of vaccination, the review delves into its potential to reduce the physical, emotional, and financial burdens associated with HPV-associated cancers. Implementing school-entry mandates for the HPV vaccine offers benefits such as increased vaccination rates, protection against HPV-related diseases, and long-term health advantages. However, challenges include ethical concerns, parental opposition, and logistical issues. Successful implementation requires clear communication, collaboration, and education, with legal and ethical considerations addressing constitutional rights, liability concerns, autonomy, and equitable access. In summary, the implementation of school-entry mandates for the HPV vaccine offers the potential for increased vaccination rates and the reduction of health disparities. However, this approach is challenged by factors such as opposition, associated costs, and legal and ethical considerations. The decision to mandate the HPV vaccine requires a delicate balance between public health priorities and individual rights, necessitating clear communication, education, and collaborative efforts to address the complexities involved.
