The Impact

Abstract Background Human papilloma virus (HPV) is the most common sexually transmitted infection in the United States, with an annual incidence rate of approximately 14 million people. The HPV vaccine has been demonstrated to be highly effective in the prevention of HPV infection and HPV-associated diseases. This study aims to evaluate the impact of HPV vaccine on the prevalence of HPV infection in the United States and evaluate the trends of disease prevalence pre- and post-HPV vaccine implementation. Methods We conducted a secondary data analysis of the National Health and Education Survey (NHANES) for trends in HPV infection from 2003 to 2016. The analysis was grouped into a pre-HPV vaccine implementation (2003–2006) cohort including 4064 females, aged 18–59 years; and a post-HPV vaccine implementation (2007–2016) cohort which included 10718 females, aged 18–59 years. Further analysis of HPV infection prevalence, pre- and post-HPV vaccine implementation, stratified by sociodemographic characteristics were conducted. Results The prevalence of HPV infection prior to HPV vaccine implementation was 43.98% (95 CI 42.71%–46.58%) compared with 40.55% (95 C.I 40.55%–40.56%) in the post-HPV vaccine implementation era. Among females with HPV infections in the post-HPV vaccine implementation cohort 82.6 (95% CI 80.41%–83.42%) were unvaccinated. In both cohorts, black females had a significantly higher prevalence of HPV with a prevalence rate of 18.56% (95% CI 18.23%–20.56%) in the pre-HPV vaccine implementation cohort, and 15.61% (95% CI 14.82 – 19.4%) in the post-HPV vaccine implementation cohort. Females with less than high school education had a higher prevalence of HPV in the pre and post- HPV vaccine implementation cohorts with prevalence rates of 25.77% (95% CI 23.44%–28.72%) and 24.96% (95% CI 23.41%–25.67%), respectively. Conclusion The results suggest that HPV infection prevalence has declined since the implementation of HPV vaccine to US national immunization program. Our findings highlight disparities in HPV infection prevalence by race and educational status, and these patterns are in keeping with HPV-associated disease such as warts and HPV-associated cancers.

Following a successful Human Papilloma Virus (HPV) vaccination pilot in 2013–2015 in Kitui county, Kenya introduced the HPV vaccine in October 2019 with a goal to immunize approximately 800,000 girls annually against HPV. Our study assessed the knowledge, attitudes, and practice of affected groups towards HPV infection and vaccination in two counties of Kenya. Semi-structured interviews from children aged between nine and thirteen years and key informants comprising of parents, head teachers, community leaders and health workers involved in HPV vaccination in health facilities from Mombasa and Tana-River counties were conducted. Content was analyzed thematically and coded for emerging themes using the QRS Nvivo 12 Plus software package. From our findings, a significant proportion of participants, especially children, have limited knowledge of the subject. Vaccination of boys was opposed by most participants. Parents and the community members are not in favor of HPV vaccination, as compared to the other groups. A similar pattern of inadequate knowledge and strongly opposed attitudes was observed in Tana-River and Mombasa. Active community involvement in primary prevention strategies may promote the uptake of the vaccine which can be achieved by robust awareness, modifying the negative beliefs about HPV vaccine and encouraging the perceptibility of HPV vaccination.

The Impact

Democratic access to scientific evidence contributes to the freedom of individuals to make informed decisions regarding scientific findings that affect their lives. In the case of the human papilloma virus (HPV), which causes cervical cancer, a debate exists regarding preventing HPV infection that is not supported by evidence-based interventions. For instance, there are positions both in favor of and against an HPV vaccine that are not evidence-based, thus preventing women from deciding freely whether to be vaccinated. Based on a communicative approach, this article describes the use of communicative focus groups and communicative daily life stories in which the researcher shares up-to-date information on HPV prevention, particularly through vaccination and screening, with high-schoolgirls in an urban context in Spain. Through the focus groups and daily life stories, the young women evaluated the impact of evidence-based dialogues, which could increase their opportunities to make free choices regarding the HPV vaccine and other medicines.

Cervical cancer (CC) is one of the most common causes of cancer-related deaths worldwide. CC is mainly caused by human papilloma virus (HPV), which can be prevented by vaccination. We conducted a cross-sectional study in secondary occupational health school (SOHS) through a questionnaire aimed to assess the awareness and knowledge regarding HPV infection of students. A total of 2248 students participated in the survey, 45.3% of them had heard about CC, while only 21.9% of them had heard about HPV; and 74.2% had no idea of the causal link between HPV infection and CC. Most participants displayed poor awareness and knowledge about HPV infection. The results suggested that age, grade, major, academic performance, etc. were correlated with higher awareness of CC, HPV and HPV infection (p < 0.05). In multivariable logistic analysis, third-grade students had the most increased awareness of CC (OR = 17.13, 95%CI: [8.11, 36.15]), HPV (OR = 6.59, 95%CI: [4.16, 10.43]) and HPV vaccine (OR = 2.78, 95%CI: [1.78, 4.32]) when compared to first-grade. Awareness and knowledge regarding HPV infection were insufficient among students in SOHS. As the future healthcare providers, these results highlight the need to supplement targeted education to improve their awareness and knowledge of HPV and vaccination.

Abstract [Purpose] Tobacco smoking has been reported to influence the prognosis of human papilloma virus (HPV)-related orophageyngeal squamous cell carcinoma (OPSCC). However, it remains to be studied whether tobacco smoking equally affects the patients treated by various modalities. [Material and Method] From 2010 through 2018, 241 patients with OPSCC were treated in a single institution, out of which 144 patients had HPV-related OPSCC. P16 immunohistochemical staining was used as a surrogate of HPV infection. Two patients was excluded because of inadequate radiation dose, and the remaining　142 patients were the subject of this study. Median age was 63.8 years and more than 80% were male. More than 70% were smokers or ex-smokers with a median pack year of 17.3. Eighty-seven patients (61.3%) were classified as stage I.[Results] For all 142 patients with HPV-related OPSCC, overall survival (OS) and disease-specific survival (DSS) were 87.0% and 93.4% in 3 years, respectively. There were no differences of OS and DSS according to the stages by 8th edition of tumor, node, and metastasis (TNM) classification and the primary sites. OS and DSS were different by the amount of tobacco smoking expressed in pack year (PY) > 30 and < 30. Also the presence of secondary cancer impacted OS. However, the influence of the amount of tobacco smoking was reduced in the patients treated by radiation therapy. [Conclusions] The impact of tobacco smoking upon the prognosis of HPV-related OPSCC seems to be dependent upon therapeutic modalities.

Objective: Human Papilloma Virus (HPV) infection is the most common sexually transmitted among young people of both sexes. It is also the main cause of cervical cancer. This study aimed at assessing students’ knowledge and health beliefs about HPV infection and the use of the vaccine.Methods: The sample of the cross-sectional study was 120 randomly selected nursing students from the Faculty of Public Health, University of Vlore “Ismail Qemali” Albania. Anonymous, self-administered questionnaire based on the literature and Health Belief Model, was used for data collection in May 2017. The questionnaire included assessment questions for students’ knowledge and health beliefs about HPV and vaccine use. Also, questions about socio-demographic characteristics were included. Data analysis included the calculation of averages, frequencies, and confidence intervals. P values ≤0.05 were accepted as statistically significant.Result: Mean age 20.3±2.2 years, 92.44 % of students were female. 65.83% of students know that HPV is a sexually transmitted infection and a vaccine is available to prevent it. Ambiguities and uncertainties exist in regard to screening with Pap test after vaccination. Perceived benefits are high for 50.83% of students. Perceived severity appeared low as only 25% of students agree that they may be affected by HPV. Statistical association, p =0.0347 was found between perceived risk and the year of study. The parents’ role in vaccination against HPV have a strong statistical association, p=0.0058 with the year of study as only 8.33 % of students in the third year agree with the fact that that parents do not allow them to be vaccinated against HPV. Conclusion: The study noted the student’s ambiguity and misconceptions about HPV infection. Low severity and lack of knowledge about the vaccine emphasizes that identifying their current level of knowledge and the main source of information are essential to provide comprehensive and appropriate health education.

The epidemic increase in the incidence of Human Papilloma Virus (HPV) related Oropharyngeal Squamous Cell Carcinomas (OPSCCs) in several countries worldwide represents a significant public health concern. Although gender neutral HPV vaccination programmes are expected to cause a reduction in the incidence rates of OPSCCs, these effects will not be evident in the foreseeable future. Secondary prevention strategies are currently not feasible due to an incomplete understanding of the natural history of oral HPV infections in OPSCCs. The key parameters that govern natural history models remain largely ill-defined for HPV related OPSCCs and cannot be easily inferred from experimental data. Mathematical models have been used to estimate some of these ill-defined parameters in cervical cancer, another HPV related cancer leading to successful implementation of cancer prevention strategies. We outline a “double-Bayesian” mathematical modelling approach, whereby, a Bayesian machine learning model first estimates the probability of an individual having an oral HPV infection, given OPSCC and other covariate information. The model is then inverted using Bayes’ theorem to reverse the probability relationship. We use data from the Surveillance, Epidemiology, and End Results (SEER) cancer registry, SEER Head and Neck with HPV Database and the National Health and Nutrition Examination Surveys (NHANES), representing the adult population in the United States to derive our model. The model contains 8,106 OPSCC patients of which 73.0% had an oral HPV infection. When stratified by age, sex, marital status and race/ethnicity, the model estimated a higher conditional probability for developing OPSCCs given an oral HPV infection in non-Hispanic White males and females compared to other races/ethnicities. The proposed Bayesian model represents a proof-of-concept of a natural history model of HPV driven OPSCCs and outlines a strategy for estimating the conditional probability of an individual’s risk of developing OPSCC following an oral HPV infection.

Given the increasing incidence of human papilloma virus (HPV)–positive head and neck cancers (HNCs), discussion of this oncologic outcome should be incorporated into HPV vaccine counseling practices. Yet, preliminary evidence shows that knowledge of the association between HPV and HNC is lacking among most medical trainees. To better characterize this deficit, we nationally assessed knowledge of HPV’s association with HNC among medical students and residents across 4 specialties (pediatrics, obstetrics and gynecology, family medicine, and otolaryngology). A total of 3141 responses from 46 states were obtained (n = 402 pediatric residents, n = 346 obstetrics/gynecology residents, n = 260 family medicine residents, n = 87 otolaryngology residents, and n = 2045 medical students). Only 40.3% of surveyed medical students and 56.1% of surveyed obstetrics/gynecology, pediatrics, and family medicine residents identified associations between persistent HPV infection and HNC. When counseling on the vaccine, nonotolaryngology residents more often discussed cervical cancer (99.8%) as compared with HNC (39.7%), commonly because of less HNC knowledge (61.5%). These results suggest that it is imperative to develop educational interventions targeted at medical students and resident trainees on the front line of HPV vaccine counseling and administration.
