Abstract
The prevalence of human papillomavirus (HPV) genotype and cervical neoplasia in women older than 64 years, who are outside the age demographic of cervical cancer screening in China, has been under-researched. This study conducts a retrospective analysis of women from a tertiary hospital in Guangzhou, with the aim to offer valuable insights for cervical cancer prevention and control in elderly women. The study incorporated 876 women, all aged 64 and above. In this age bracket, the prevalence rate of any HPV genotype was found to be 19.27%. The top six HR HPV genotypes were HPV 16, HPV 52, HPV 58, HPV 31, HPV 33, and HPV 18. The persistence rate of any HPV type over a 24-month period in this age group was as high as 33.33%. Among women over 64, around 16.47% of HPV-positive patients were diagnosed with cervical cancer. HPV 58 infection was the most substantial risk factor for histological CIN2+ (OR 3.556; 95% CI, 1.107-11.415; p = 0.032) in women over 64 years of age with HPV-positive/NILM status. In conclusion, the burden of HPV infection is significant among women over 64 years in Guangzhou. Re-evaluation of cervical cancer screening strategies for women after the age of 64 is imperative. Moreover, the HPV 16/18/52/58 genotype model could serve as an alternative triage approach to identify histological CIN2+ among elderly women with HPV-positive/NILM status.

Abstract
Background Due to the heterogeneity of existing studies and wide range of human papilloma virus (HPV) prevalence in India, further research into the incidence of HR-HPV and its spectrum of genotypes is essential to develop screening policies. This study aimed to determine the incidence and demographic distribution of HR-HPV among cisgender female patients attending a tertiary care facility in North India. Materials and Methods This study was conducted in the Department of Obstetrics and Gynaecology, SGRR Institute of Medical and Health Sciences, Dehradun, India. HPV-DNA test results of 653 female patients were assessed for HR-HPV positivity, genotyping, and age-based differences via Chi-square analysis. Results Overall prevalence of HR-HPV was 4.90%, HPV-16 was 1.37%, HPV-18 was 0.76%, and HPV non-16,18 was 2.7%. In patients ≤ 50 years, prevalence of HPV-16 was 0.97%, HPV-18 was 0.38%, and HR-HPV non-16,18 was 2.71%. In patients > 50 years, prevalence of HPV-16 was 2.89%, HPV-18 was 2.17%, and HR-HPV non-16,18 was 2.89%. The difference in the prevalence of HPV-16,18 between patients ≤ and > 50 years was found to be highly statistically significant (P = 0.007485). The difference in the prevalence of total HR-HPV between patients ≤ and > 50 years was not found to be statistically significant (P = 0.059905). Conclusion Our study's finding of higher HR-HPV positivity rates in patients > 50 years emphasizes the need for continued HR-HPV-DNA-based screening of this cohort. With widespread use in post-menopausal patients, HPV screening can serve as an important armamentarium in the fight against cervical cancer.

Abstract
BACKGROUND Cervical cancer is strongly associated with human papillomavirus (HPV) infection. In this retrospective study, we analyzed the data of postmenopausal women who were tested for HPV in Nanjing First Hospital from 2019 to 2021. METHODS We retrospectively analyzed the data of 14,608 postmenopausal women aged 45-90 years, who underwent HPV examination in Nanjing First Hospital between January 2019 and December 2021. All participants were tested for 23 HPV genotypes. We subsequently analyzed the infection rate and evaluated the distribution of HPV using the chi-square test. RESULTS Our results showed that the HPV infection rate in postmenopausal women in Nanjing, China was 22.36%. In terms of age group, the infection rate was 19.54%, 24.30%, 26.58%, and 14.99% in those aged ≤ 50, 51-60, 61-70, and ≥ 71 years, respectively. The most common HPV subtypes were HPV52 (22.1 3%), HPV58 (15.86%), HPV53 (14.17%), HPV16 (12.61%), and HPV81 (11.66%), in that order. The single-HPV infection rate was 14.23%, and the multiple-genotype infection rate was 8.14% (1189/14,608). CONCLUSIONS This study showed that in Nanjing, China, the different age groups of post-menopausal women could have different rates of HPV infection, and the most common types were HPV52, HPV58, HPV53, HPV16 and HPV81. These findings highlighted the importance of understanding the epidemiology of HPV infection in specific populations, such as postmenopausal women in Nanjing, China. The results could provide valuable information for healthcare professionals and policymakers to develop targeted prevention and screening strategies for reducing the burden of HPV-related diseases in this population.

Abstract
BACKGROUND Persistent high-risk human papillomavirus (HR-HPV) infection is an important factor in the development of cervical cancer, and human papillomavirus type 16 (HPV-16) is the most common HR-HPV type worldwide. The oncogenic potential of HPV-16 is closely related to viral sequence variation. METHODS In order to clarify the variant characteristics of HPV-16 E6 and E7 genes in central China, E6 and E7 sequences of 205 HPV-16 positive samples were amplified by polymerase chain reaction. PCR products of E6 and E7 genes were further sequenced and subjected to variation analysis, phylogenetic analysis, selective pressure analysis and B-cell epitope prediction. RESULTS Twenty-six single nucleotide variants were observed in E6 sequence, including 21 non-synonymous and 5 synonymous variants. Twelve single nucleotide variants were identified in E7 sequence, including 6 non-synonymous and 6 synonymous variants. Four new variants were found. Furthermore, nucleotide variation A647G (N29S) in E7 was significantly related to the higher risk of HSIL and cervical cancer. Phylogenetic analysis showed that the E6 and E7 sequences were all distributed in A lineage. No positively selected site was found in HPV-16 E6 and E7 sequences. Non-conservative substitutions in E6, H31Y, D32N, D32E, I34M, L35V, E36Q, L45P, N65S and K75T, affected multiple B-cell epitopes. However, the variation of E7 gene had little impact on the corresponding B-cell epitopes (score < 0.85). CONCLUSION HPV-16 E6 and E7 sequences variation data may contribute to HR-HPV prevention and vaccine development in Jingzhou, central China.

Abstract
OBJECTIVES Human papillomavirus (HPV) infection is closely associated with cervical cancer, especially the persistent infection of high-risk HPV (HR-HPV) genotypes. Therefore, investigating the HPV prevalence, age-specific, genotype distribution and the impact of the COVID-19 pandemic among large populations was essential for HPV screening and optimising vaccination. DESIGN This was a cross-sectional study. METHODS A total of 38 056 cervical epithelial cell specimens were collected in Weifang city from January 2018 to December 2022. The study was divided into seven age groups based on the age of the participants. HPV genotype testing was performed by using a commercial kit which is designed for the detection of 23 HPV genotypes. RESULT A total of 8998 women were infected with HPV, with an overall positive rate of 23.64% (8998/38 056). Single infection of HPV was dominant among different age groups, which accounted for 71.33% of total infections. The most prevalent genotype was HR-HPV 16 (4.33%), followed by 52, 58, 53 and 68. Low-risk HPV (LR-HPV) 42 exhibited the highest prevalence (2.19%) among six LR-HPV genotypes, representing a novel finding. There was a significant difference in the prevalence across different age groups (p<0.01), with the highest prevalence in the group under 25 years old. During the 3 year COVID-19 breakout period, the number of HPV samples received in 2020, 2021 and 2022 was reduced by 24.03%, 14.79% and 24.76%, respectively. In 2018-2022, the annual prevalence varied between 21.09% and 25.30%, with a decreasing trend, while the prevalence of HR-HPV 39, 56, 31 and LR-HPV 42 increased. CONCLUSION This study indicates a high-HPV infection rate and age-specific distribution characteristics of HPV genotype infections, as well as analyses of the impact of the COVID-19 outbreak on the HPV prevalence, which provides an epidemiological basis for the control and prevention of HPV infection in this region.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccination is a key initiative to promote the WHO global strategy to accelerate the elimination of cervical cancer, and this study aimed to investigate the current status of HPV infection and genotypic characteristics of the population under the impact of age-expansion of nine-valent HPV vaccination policy in China. METHODS The clinical data of 60,685 subjects who were admitted in the Renmin Hospital of Wuhan University and underwent HPV genotyping from January 2017 to October 2022 were retrospectively analyzed. RESULTS The total number of positive HPV genotyping in the included population was 10,303, with a positivity rate of 17.0 %. The HPV positivity rate in the male and female populations increased slowly year by year, with a higher rate of positivity in men (32.7 %) than in women (16.7 %) (P < 0.001). HPV was predominantly single infection in all populations, with higher prevalence of high-risk HPV than low-risk HPV in females, while low-risk HPV infection was predominant in the male population. The age distribution of female subjects infected with HPV, with HPV52 as the most common type, showed a bimodal pattern. As for HPV infected male subjects, HPV6 was the main type, and there was no bimodal age distribution. The expanded age vaccination of the nine-valent HPV vaccine will result in 42.4 % efficiency of vaccine protection for 49.9 % of age-eligible women. If the nine-valent HPV vaccine were open to males in China, it would reduce HPV infections in men by 56.4 %. CONCLUSIONS The HPV positivity rate in the population remains high and tends to increase, and the age-expansion of the nine-valent HPV vaccine would contribute to reducing the threat of disease caused by HPV infection for age-eligible women. Moreover, attention should be paid to enhancing HPV screening in males and opening up vaccination when appropriate.

Abstract
ObjectivesWe investigated HPV genotypes in a large cohort of patients with definitive cervical histologic diagnosis.MethodsHPV testing was performed by real-time PCR assay, including 18 high-risk HPV (hrHPV) and 3 low-risk HPV (lrHPV). Totally 61,422 patients with documented HPV genotyping results within 6 months before cervical histologic diagnoses were included.ResultsHrHPV positive rate was 55.1% among all tested cases with the highest in adenosquamous carcinoma (94.1%), followed by squamous cell carcinoma (SCC) (93.7%), cervical intraepithelial neoplasia 2/3 (CIN2/3) (92.8%). HrHPV positive rates were significantly higher in high-grade squamous lesions than in those in glandular lesions. HPV16 was the most common genotype followed by HPV52 and HPV58 in CIN2/3. The most frequent hrHPV genotype in adenocarcinoma in situ (AIS) was HPV18, followed by HPV16, HPV45 and HPV52. In SCC cases, HPV16 was the most common type followed by HPV58, HPV52, HPV18 and HPV33. However, HPV18 showed significantly higher prevalence in adenocarcinoma and adenosquamous carcinoma than in that in SCC. Theoretically, the protective rates of 2/4-valent and 9-valent vaccine were 69.1% and 85.8% for cervical cancers.ConclusionsThe prevalence of HPV genotypes in Chinese population was different from that in Western population. Some hrHPV types were identified in cervical precancerous lesions and cancers, which are not included in current HPV vaccines. These data provide baseline knowledge for future HPV vaccine development.

Abstract
PURPOSE This study assesses HPV prevalence and genotype distribution in Lebanon, and identifies differentials in HPV infection, infection with multiple genotypes, and with high-risk genotypes, by sex, age, and year of data collection. METHODS Study participants comprised 1042 female and 160 male participants between 2006 and 2018. HPV genotyping was done by PCR and hybridization (2006-2013) or real-time PCR (2013 onwards). Diversity of HPV genotypes across gender, age groups, and years of data collection was tested by applying Shannon Diversity Index. RESULTS The overall HPV prevalence was 44.8% among study participants, and threefold higher in women than men. Single HPV infection was seen in two-third of HPV-positive participants. Women were less likely to be infected with multiple HPV strains, but more likely to be infected with high-risk or mixed-risk HPV genotypes. HPV-16 (11.0%, 9.8%) and HPV-53 (8.5%, 4.9%) were the most prevalent high-risk HPV genotypes in women and men, respectively, while HPV-18 prevalence was 4.9% in men and 3.1% in women, while HPV-59 prevalence was 6.6% in men and 2.1% in women. Samples collected post-2011 from women showed twice higher odds of HPV infection than those collected earlier and were threefold more likely to be infected with multiple HPV strains, and twice more likely to be infected with high-risk genotypes compared to those tested earlier. Women scored higher on Shannon index indicating high diversity in HPV types and frequency, with trend of increased diversity over time. While the odds of HPV infection remained associated with sex and temporal trend in multivariable analysis, odds of having high-risk genotypes was mainly associated with infection with multiple HPV strains. CONCLUSION Our study showed high diversity in HPV genotypes and an increasing trend of infection with multiple and high-risk genotypes in recent years. Findings underscore the need for effective screening/surveillance and HPV vaccination programs.

Abstract
Human papilloma virus (HPV) infection and its associated disease are major problems affecting millions of individuals around the world. The distribution of HPV genotypes is specific to different areas and different populations. Therefore, understanding the prevalence and genotype distribution of HPV in different populations in different geographical regions is essential to optimize HPV vaccination strategies and to maximize vaccine effects. In this study, 34,076 women from January 2016 to July 2022 were retrospectively analyzed at Liaocheng People's Hospital. Of these, 7540 women were high-risk HPV positive and the infection rate was 22.13%. The top ten genotypes were as follows in descending order: HPV16, HPV52, HPV58, HPV53, HPV39, HPV59, HPV66, HPV51, HPV18, and HPV56 and the least frequent genotypes were, in order, HPV 26, HPV45, and HPV82. The HPV16 positive infection rate was 25.37% and was reduced with the increase in the number of individuals who had undergone HPV screening. The HPV52 infection rate increased with increasing numbers of individuals undergoing HPV screening, and then remained unchanged. The proportion of 20-29-year-olds among all positive women began to decrease since the vaccine was available in 2018. The 30-39-year-old group accounted for the highest percentage of positive women, and the 50-59-year-old group of HPV-positive women with cervical cancer accounted for most infections. This study confirmed that HPV16, HPV52, HPV 58, and HPV53 is widely distributed in this population and the total HR-HPV infection rate remains high in this region. Our findings indicate that prevention of HPV infection in this region still faces important challenges.
