Abstract
BACKGROUND Human papillomavirus (HPV) is an oncogenic virus and the commonest sexually transmitted pathogen worldwide. Appropriate sampling is an important factor in infection management. This study aimed to compare the efficacy of cotton swabs (CS) and nylon-flocked swabs (NFS) in sampling for HPV-DNA PCR testing in male patients with genital warts. METHODS The study included men with genital warts who presented to the urology outpatient clinic of Antalya Medical Park Hospital. Before wart treatment, multisite sampling of the penis and genital area was performed separately with CS and NFS. The samples were analyzed for HPV-DNA using real-time PCR. RESULTS The study included 45 men with a mean age of 32.1 ± 8.6 years. At least one HPV type was detected in all 45 patients with NFS sampling and 44 patients with CS sampling (total HPV types detected: 106 and 84, respectively). NFS sampling detected 52 high-risk HPV types in 37 of the 45 patients, while CS sampling detected 37 high-risk types in 19 patients (p = 0.029). NFS sampling also detected a total of 54 low-risk HPV types in all 45 patients, versus 47 low-risk HPV types in 41 patients with CS sampling. Multiple HPV types were detected in 30 patients with NFS and 17 patients with CS (p = 0.001). CONCLUSION NFS were more effective than CS for HPV-DNA testing in men with genital warts. NFS were superior to CS in detecting multiple-type HPV infection and high-risk HPV types. The use of NFS should be recommended for HPV-DNA PCR testing in men.

Abstract
BACKGROUND Danish women-who were HPV-vaccinated as girls-are now reaching an age where they are invited to cervical cancer screening. Because of their expected lower cervical cancer risk, we must reassess our screening strategies. We analyzed Danish HPV-vaccinated women's outcomes after the first screening test at age 23. METHODS AND FINDINGS Our study was embedded in Danish routine cytology-based screening. We conducted an observational study and included women born in 1994, offered the 4-valent HPV vaccine at age 14, and subsequently invited to screening at age 23. Cervical cytology was used for diagnostics and clinical management. Residual material was HPV tested with Cobas® 4800/6800. The most severe histology diagnosis within 795 days of screening was found through linkage with the Danish National Pathology Register. We calculated the number of women undergoing follow-up (repeated testing and/or colposcopy) per detected cervical intraepithelial neoplasia (CIN2+). A total of 6021 women were screened; 92% were HPV-vaccinated; 12% had abnormal cytology; 35% were high-risk HPV-positive, including 0.9% HPV16/18 positive, and 20% had follow-up. In women that were cytology-abnormal and HPV-positive (Cyt+/HPV+), 610 (98.5%) had been followed up, and 138 CIN2+ cases were diagnosed, resulting in 4.4 (95% CI 3.9-5.2) women undergoing follow-up per detected CIN2+. In contrast to recommendations, 182 (12.2%) cytology-normal and HPV-positive (Cyt-/HPV+) women were followed up within 795 days, and 8 CIN2+ cases were found, resulting in 22.8 (95% CI 13.3-59.3) women undergoing follow-up per detected CIN2+. CONCLUSION Overall, HPV prevalence was high in HPV-vaccinated women, but HPV16/18 had largely disappeared. In the large group of cytology-normal and HPV-positive women, 23 had been followed up per detected CIN2+ case. Our data indicated that primary HPV screening of young HPV-vaccinated women would require very effective triage methods to avoid an excessive follow-up burden. TRIAL REGISTRATION Trial registration number: NCT0304955.

Abstract
BACKGROUND The aims of the study were to determine, in the urine and oral samples of young adults, the genotype-specific prevalence of Human Papilloma Virus (HPV) infection, the HPV DNA type-specific prevalence in unvaccinated and vaccinated individuals, and the determinants of HPV infection. METHODS Selected participants were asked to fill in a self-administered questionnaire and to self-collect urine and saliva samples. RESULTS Among the 1002 participants, 81 (8.1%) resulted positive for HPV DNA. The most common low-risk genotype was HPV 42 (2.2%), followed by HPV 43 (0.8%), and 40 (0.5%). The HPV 51 was the most common high-risk genotype (1.5%) followed by HPV 66 (1%) and HPV 68 (1%), and no participants were infected with HPV genotypes 18, 33, 45. Females, those who have had one or more occasional sexual partner, those who never/rarely/sometimes used condoms during their sexual activity, those with a previous diagnosis of sexually transmitted infection, and those who were not vaccinated were more likely to be tested positive for HPV infection. CONCLUSIONS The low prevalence of genital HPV infections has provided evidence of the effectiveness of HPV vaccination both in vaccinated and not yet vaccinated subjects through herd immunity and indicated its decisive role in the changing epidemiology of circulating HPV genotypes in the population.

Abstract
Uterine cervical intraepithelial abnormalities and cancer development may also depend upon biological problems that arise as a result of complex molecular disturbances within the vaginal space, in addition to the widely known causative effect of human papillomavirus (HPV) infection. Chronic oxidative stress is a consequence of oxygen reduction in the vaginal space. Reactive oxygen species (ROS) and free radicals are yet unrecognizable causative agents and are probably very important factors for cervical intraepithelial neoplasia (CIN) and cancer development. The intermediate compounds of oxygen reduction on these metabolic pathways are superoxide anion (O 2 ˙ - ), hydrogen peroxide (H2O2), hydroxide ions (OH-), and hydroxyl radical (HO˙). Considering these points, the aim of this work was to summarize how these compounds can damage all molecules, including DNA, of vulnerable metaplastic cervical epithelium. Finally, in some women with a poor immune defense system, ROS alone or accompanied by a high-risk HPV type may promote all levels of CIN and cancer development.

Targeted Disruption of E6/p53 Binding Exerts Broad Activity and Synergism with Paclitaxel and Topotecan against HPV-Transformed Cancer Cells. Cancers (Basel) 2021; 14:cancers14010193.

Abstract
Simple Summary The identification of new specific anti-human papillomavirus (HPV) drugs is highly needed, as HPV-induced cancers still represent a significant medical issue. The aim of this study was to analyze in more detail the therapeutic potential of a compound, Cpd12, that acts by blocking the binding between HPV E6 oncoprotein and cellular tumor suppressor p53. We demonstrated that by blocking such an interaction, driven by highly conserved residues among oncogenic HPVs, Cpd12 exhibits broad activity against cervical cancer cell lines infected by different HPV genotypes and HPV-positive head-and-neck cancer cells. Interestingly, Cpd12 also showed the ability to inhibit cancer cell migration and to increase the activity of chemotherapeutic drugs such as taxanes and topoisomerase inhibitors. These findings improve the knowledge about the in vitro efficacy of Cpd12, paving the way to preclinical studies to develop new therapeutic strategies against HPV-induced tumors. Abstract High-risk human papillomaviruses (HR-HPV) are the etiological agents of almost all cervical cancer cases and a high percentage of head-and-neck malignancies. Although HPV vaccination can reduce cancer incidence, its coverage significantly differs among countries, and, therefore, in the next decades HPV-related tumors will not likely be eradicated worldwide. Thus, the need of specific treatments persists, since no anti-HPV drug is yet available. We recently discovered a small molecule (Cpd12) able to inhibit the E6-mediated degradation of p53 through the disruption of E6/p53 binding in HPV16- and HPV18-positive cervical cancer cells. By employing several biochemical and cellular assays, here we show that Cpd12 is also active against cervical cancer cells transformed by other HR-HPV strains, such as HPV68 and HPV45, and against a HPV16-transformed head-and-neck cancer cell line, suggesting the possibility to employ Cpd12 as a targeted drug against a broad range of HPV-induced cancers. In these cancer cell lines, the antitumoral mechanism of action of Cpd12 involves p53-dependent cell cycle arrest, a senescent response, and inhibition of cancer cell migration. Finally, we show that Cpd12 can strongly synergize with taxanes and topoisomerase inhibitors, encouraging the evaluation of Cpd12 in preclinical studies for the targeted treatment of HPV-related carcinomas.

Abstract
INTRODUCTION High-risk HPV infections are related to several epithelial cancers. Despite the availability of prophylactic vaccines, HPV infections are still responsible for about 5% of all human malignancies worldwide. While therapeutic vaccines are ongoing clinical trials, genotoxic agents and surgical interventions represent current clinical treatments, with no specific anti-HPV drugs yet available in the clinics. AREAS COVERED We offer a comprehensive report of small molecules in preclinical studies proposed as potential anticancer agents against HPV-driven tumors. Given the importance of HPV oncoproteins for cancer maintenance, particularly E6 and E7, we present a classification of both non-targeted and targeted agents, with a further subdivision of the latter into two categories according to their either direct or indirect activity against viral protein functions. EXPERT OPINION Prophylactic vaccines can prevent the insurgence of HPV-related cancers, but have no effect against pre-existing infections. Moreover, their high cost, genotype-restricted effect and the growing worldwide distrust for vaccines make the availability of a specific drug an unmet medical need. Different viral early proteins emerge as ideal candidates for drug development. We highlight the most promising strategies and address future challenges in this field to herald the prospect of a specific therapeutic regimen against HPV-related cancers.

Abstract
Professor Harald zur Hausen, „Vater der HPV(humane Papillomviren)-Impfung“, wurde in diesem Jahr 85 Jahre alt. Aus diesem Anlass wird in einem Rückblick auf die Einführung der HPV-Impfung vor 14 Jahren geschaut, und es werden die Widerstände aufgezeigt, welche die ersten Jahre dieser segensreichen Impfung begleiteten. Schon früh wurde 2007 die Impfung für die Mädchen in das Standardimpfprogramm der Ständigen Impfkommission am Robert Koch-Institut (STIKO) aufgenommen, erst 11 Jahre später kam es zur Empfehlung auch für Jungen. Die Impfquoten in beiden Gruppen sind mit ca. 50 % in Deutschland weiterhin im Vergleich zu anderen Ländern mit Schulimpfprogrammen zu niedrig. Dabei gibt es keine wissenschaftlichen Bedenken mehr gegenüber der HPV-Impfung, die sich in weltweiten Studien als sicher und wirksam erwiesen hat. Nicht nur die Verminderung der Krebsvorstufen, sondern auch von Zervixkarzinomen konnte neben der starken Reduktion von Fällen an Condylomata acuminata bei den Geimpften inzwischen in Real-Life-Studien gezeigt werden, weshalb die WHO (World Health Organization) als Impfziel die Eliminierung des Zervixkrebses durch Aufbau einer Bevölkerungsimmunität erklärt hat. Dazu sollten weitere Anstrengungen unternommen werden, die Impfquoten in Deutschland zu erhöhen, was auch in einem entsprechenden Appell der Gesundheitsministerkonferenz im Juni 2021 eingeflossen ist.
