Abstract
INTRODUCTION This study investigated the awareness, perceptions, and acceptance of human papillomavirus (HPV) vaccination for children among parents in Hong Kong. It also explored factors associated with, and differences in, vaccine acceptance and hesitancy between parents of girls and boys. METHODS Parents of boys or girls in Primary 5 to 6 were invited to participate in an online survey through an established health and lifestyle e-platform. RESULTS Overall, 851 parents completed the survey: 419 (49.2%) had daughters, 348 (40.9%) had sons, and 84 (9.9%) had children of both genders. Parents who enrolled their children into the Childhood Immunisation Programme were more likely to accept HPV vaccination (79.7% vs 33.7%, odds ratio [OR]=7.70; 95% confidence interval [CI]=5.39-11.01; P<0.001); parents of girls were more likely to accept than parents of boys (86.0% vs 71.8%, OR=2.40; 95% CI=1.67-3.46; P<0.001). Among parents of girls and boys, the main reasons for HPV vaccination acceptance were prevention of cancers (girls: 68.8% and boys: 68.7%), prevention of sexually transmitted diseases (girls: 67.3% and boys: 68.3%), and optimal timing before initiation of sexual activity (girls: 62.8% and boys: 59.8%). Vaccine hesitancy was mainly associated with concerns about serious side-effects (girls: 66.7% and boys: 68.0%) and the belief that their children were too young (girls: 60.0% and boys: 54.0%). CONCLUSION Parents in Hong Kong are hesitant about HPV vaccination for their sons. This barrier could be removed by providing information to correct vaccine safety misconceptions and offering a gender-neutral vaccination programme through the school-based Childhood Immunisation Programme.

Abstract
The interaction between cervicovaginal virome, bacteriome and genital inflammation has not been extensively investigated. We assessed the vaginal DNA virome from 33 South African adolescents (15-19 years old) using shotgun DNA sequencing of purified virions. We present analyses of eukaryote-infecting DNA viruses, with a focus on human papillomavirus (HPV) genomes and relate these to the vaginal bacterial microbiota (assessed by 16S rRNA gene sequencing) and cytokines (assessed by Luminex). The DNA virome included single-stranded (Anelloviridae, Genomoviridae) and double-stranded DNA viruses (Adenoviridae, Alloherpesviridae, Herpesviridae, Marseilleviridae, Mimiviridae, Polyomaviridae, Poxviridae). We identified 110 unique, complete HPV genomes within two genera (Alphapapillomavirus and Gammapapillomavirus) representing 40 HPV types and 12 species. Of the 40 HPV types identified, 35 showed positive co-infection patterns with at least one other type, mainly HPV-16. HPV-35, a high-risk genotype currently not targeted by available vaccines, was the most prevalent HPV type identified in this cohort. Bacterial taxa commonly associated with bacterial vaginosis also correlated with the presence of HPV. Bacterial vaginosis, rather than HPV, was associated with increased genital inflammation. This study lays the foundation for future work characterizing the vaginal virome and its role in women's health.

Abstract
Human papillomaviruses (HPVs) are etiologically associated with various benign and malignant neoplasms of cutaneous and mucosal epithelia. We describe an improved diagnostic protocol for comprehensive characterization of causative HPV types in common warts, in which broad-spectrum PCRs followed by Sanger sequencing, two previously described and seven newly developed type-specific quantitative real-time PCRs (qPCRs) coupled with the human beta-globin qPCR were used for: (i) diagnosis of HPV infection in warts; (ii) estimation of cellular viral loads of all HPV types detected; and (iii) determination of their etiological role in 128 histologically confirmed fresh-frozen common wart tissue samples. A total of 12 different causative HPV types were determined in 122/126 (96.8%) HPV-positive warts, with HPV27 being most prevalent (27.0%), followed by HPV57 (26.2%), HPV4 (15.1%), HPV2 (13.5%), and HPV65 (7.9%). The cellular viral loads of HPV4 and HPV65 were estimated for the first time in common warts and were significantly higher than the viral loads of HPV2, HPV27, and HPV57. In addition, we showed for the first time that HPV65 is etiologically associated with the development of common warts in significantly older patients than HPV27 and HPV57, whereas HPV4-induced warts were significantly smaller than warts caused by HPV2, HPV27, HPV57, and HPV65.

Abstract
BACKGROUND Three genera of human papillomavirus (HPV) infect the oral cavity and oropharynx- alpha (α), beta (β) and gamma (γ). While α-HPV infection is an established risk factor for head and neck cancers (HNC), the role of other genera remains unclear. We aimed to estimate the effect of α-, β-, γ-HPV on HNC using a hospital-based case-control study. METHODS We recruited incident HNC cases (396) and controls (439), frequency-matched by age and sex from four main referral hospitals in Montreal, Canada. We collected information on sociodemographic and behavior characteristics using in-person interviews, and tested rinse, brush and tumor specimens for HPV genotypes. We estimated adjusted odds ratios (aOR) and 95% confidence intervals (CI) for the effect of HPV on HNC using logistic regression, adjusting for confounding. We conducted probabilistic bias analysis to account for potential exposure misclassification, selection bias, and residual confounding. RESULTS α-HPV genus had a strong effect on HNC, particularly HPV16 (aOR=22.6; 95% CI: 10.8, 47.2). β-HPV was more common among controls (aOR=0.80; 95% 0.57, 1.11). After adjustment for HPV16, we found weaker evidence for γ-HPV (aOR= 1.29; 95% CI: 0.80, 2.08). Combined bias analyses for HPV16 increased the strength of the point estimate, but added imprecision (aOR=54.2, 95% CI: 10.7, 385.9). CONCLUSIONS α-HPV, especially HPV16, appears to increase the risk for HNC, while there is little evidence for an effect of β- or γ-HPV. β-HPV may have a preventive effect, while γ-HPV may increase the risk of HNC, although to a lesser extent than that of α-HPV. Results for cutaneous HPV were imprecise and less conclusive. Due to possible epidemiologic biases, the true relation between HPV and HNC could be underestimated in the literature. Further improvement in current methods and more studies of the biologic mechanisms of the three genera in HNC development are warranted.

Abstract
OBJECTIVES Human papillomavirus (HPV) testing can be incorporated into the post-treatment pathway of cervical intraepithelial neoplasia (CIN) to confirm disease-free status. To inform a post-treatment strategy based on risk of recurrence, we modelled disease and economic outcomes. METHODS The current Alberta, Canada, post-treatment care pathway-cytology testing with colposcopy assessment-was compared with 6 other scenarios incorporating cytology, HPV testing, or both tests at different time points in a modelling study based on a microsimulation program. Input parameter values for the screening participation, screening age groups, and follow-up options and test compliance for HPV, cytology, and colposcopy were varied, based on Alberta cervical cancer screening program data. Health outcomes over the short- and long-term were projected, which incorporated the increasing population-level coverage of HPV vaccination. Lifetime incremental cost-effectiveness ratios (ICERs) were used to evaluate economic outcomes and descriptive statistics compared with numbers of tests, visits, and procedures as well as changes in incidence and mortality rates between the scenarios. RESULTS At 5 years after implementation of the "HPV testing alone at 6 and 18 months" post-treatment pathway, the number of colposcopies dropped by 36% and the number of pre-cancer treatments, by 6%. Lifetime ICERs were CAD $6170 versus $248,495 per quality-adjusted life-year compared with the status quo pathway. Cervical cancer incidence and mortality rates decreased significantly and similarly in all scenarios. CONCLUSION Strategies that involve HPV testing in CIN post-treatment follow-up care are expected to be more cost effective with improved clinical outcomes than traditional cytology and colposcopy-based follow-up.

Abstract
Oral infection by Human Papillomavirus (HPV) has recently gained great attention because of its involvement in the development of a subset of head and neck squamous cell carcinoma. The role of specific Alpha-HPVs in this regard has been well established, whereas the contribution of other genera is under investigation. Despite their traditional classification as “cutaneous” types, Beta and Gamma HPVs are frequently detected in oral samples. Due to the lack of a standardized protocol, a large variety of methodologies have been used for oral sample collection, DNA extraction, HPV detection and genotyping. Laboratory procedures influence the evaluation of oral HPV prevalence, which largely varies also according to the population characteristics, e.g., age, gender, sexual behavior, Human Immunodeficiency Virus (HIV) status. Nevertheless, oral infection by Beta and Gamma HPVs seems to be even more common than Alpha-HPVs. The latter is 5–7% in the general population, and increases up to 30% approximately in HIV-infected men who have sex with men. Despite major advances in the evaluation of oral HPV prevalence, its natural history is still little understood, especially for Beta and Gamma HPVs. The latest technologies, such as Next Generation Sequencing (NGS), can be exploited to gain new insights into oral HPV, and to improve the identification of novel HPV types.

Abstract
Squamous intraepithelial lesions (SIL) and cervical cancer are primary due to suboptimal immune response against human papillomavirus (HPV). The FASL/FAS system is a trigger of extrinsic pathway apoptosis. The distribution of polymorphisms rs1800682 (-670 A > G) FAS and rs763110 (-844C > T) FASL was studied in cervical smears from 372 females (182 with stable or regressed low-grade SIL (LSIL) (groupI) and a group of 190 high-grade SIL (HSIL) (groupII). No significant differences were observed for rs1800682 in FAS between the study groups. In contrast, rs763110 CC genotype of FASL was found in 35.7% of group I females, and in 50.5% of group II (p = 0.0027; OR = 1.83 (95% CI = 1.21-2.79)). When only females infected with high-risk HPV were analysed, these differences were even higher (p = 0.0024; OR = 2.21 (95% CI = 1.30-3.75)). CC genotype in FASL seems to be associated with increased risk of LSIL to HSIL progression suggesting a role in HPV tolerance, persistent infection, and HSIL development.

Abstract
INTRODUCTION Human papillomavirus (HPV) infection and related cancers are a major cause of morbidity and mortality worldwide. Routine vaccination against HPV is recommended for patients starting at age 9-12 years. Discussing this vaccine with parents of young children can be challenging for clinicians. Barriers include parental beliefs, strength and quality of clinician recommendations, physician knowledge of HPV disease and vaccines, and provider comfort levels with discussing sexuality. METHODS Our interactive workshop began with a predidactic role-play session addressing common concerns about the HPV vaccine where participants took turns playing a concerned parent or provider. We then gave a 30-minute didactic lecture and conducted a postdidactic role-play session to practice communication skills in promoting the HPV vaccine. All participants completed pre- and postintervention knowledge and skill self-assessments. RESULTS Twenty-eight pediatric residents and medical students participated. We observed significant improvement in their ability to appropriately recommend the HPV vaccine in the postdidactic role-play (all ps < .02). Learner knowledge improved from pre- to postintervention (from 34% to 100%, p < .0025, based on average score), as did self-perceived comfort and confidence levels (from 3.6 to 4.3, p < .0001, average score based on a 5-point Likert scale). DISCUSSION An interactive workshop utilizing role-play supplemented by a didactic lecture was effective in improving participants' knowledge, communication skills, comfort levels, and confidence levels regarding HPV disease and vaccines. The workshop offers a practical and interpersonal approach to improving learners' skills in discussing the HPV vaccine with parents.

Abstract
Papillomaviruses (PVs) are a diverse group of host species-specific DNA viruses, etiologically linked with various benign and malignant neoplasms of cutaneous and mucosal epithelia. Here, we describe the detection and characterization of the first two PVs naturally infecting Japanese macaques (Macaca fuscata), including the determination of their etiological association(s) with the development of original neoplasms. The molecular and phylogenetic analyses were performed on complete genome sequences of Macaca fuscata PV types 1 (MfuPV1) and 2 (MfuPV2), which were completely sequenced in samples of a malignant oral tumor and benign anogenital neoplasm of Japanese macaques, respectively. Subsequently, two type-specific quantitative real-time PCRs were developed to estimate viral loads of MfuPV1 and MfuPV2 and to evaluate their etiological roles. The in silico molecular analyses revealed that both viral genomes encode characteristic PV proteins with conserved functional domains and have a non-coding genomic region with regulatory sequences to regulate and complete the viral life cycle. However, additional experimental evidence is needed to finally confirm the presence and biological functionality of the molecular features of both novel PVs. While MfuPV1, together with PVs identified in other macaques, is classified into the Alphapapillomavirus (Alpha-PV) species 12, MfuPV2 is most likely a representative of the novel viral species within the Alpha-PV genus. Their relatively high viral loads suggest that both PVs are etiologically linked with the development of the original neoplasms.

Abstract
BACKGROUND Previous investigations studying the association of DNA viruses with salivary gland tumors (SGTs) have led to conflicting results. The aim of this study was to determine the prevalence of different DNA viruses by using a highly sensitive assay in a multi-center series of over 100 fresh frozen salivary gland samples. METHODS DNA was isolated from 84 SGTs (80 parotid tumors and 4 submandibular gland tumors) and 28 normal salivary tissue samples from 85 patients in Northeast Italy. Using a highly sensitive type-specific multiplex genotyping assay, we analyzed the samples for the presence of DNA from 62 different viruses including 47 papillomaviruses, 10 polyomaviruses, and 5 herpesviruses. RESULTS We observed a high prevalence of beta human papillomavirus DNA in malignant tumors. In contrast, polyomavirus DNA was present in benign, malignant, and non-tumor control samples. Most striking was the significant distribution of herpesvirus DNA in the SGT samples, in particular the high prevalence of Epstein-Barr type 1 and type 2 DNA in Warthin's tumor samples. CONCLUSION Our data provides evidence for the presence of DNA viruses in SGTs. Mechanistic studies are needed to further attribute tumor formation to these viruses.
