The human papillomavirus (HPV) is threatening human health as it spreads globally in varying degrees. On the other hand, the speed and scope of information transmission continues to increase, as well as the significant increase in the number of HPV-related news reports, it has never been more important to explore the role of media news coverage in the spread and control of the virus. Using a decreasing factor that captures the impact of media on the actions of people, this paper develops a model that characterizes the dynamics of HPV transmission with media impact, vaccination and recovery. We obtain global stability of equilibrium points employing geometric method, and further yield effective methods to contain the HPV pandemic by sensitivity analysis. With the center manifold theory, we show that there is a forward bifurcation when R0=1. Our study suggested that, besides controlling contact between infected and susceptible populations and improving effective vaccine coverage, a better intervention would be to strengthen media coverage. In addition, we demonstrated that contact rate and the effect of media coverage result in multiple epidemics of infection when certain conditions are met, implying that interventions need to be tailored to specific situations.

BACKGROUND: Anal condyloma acuminatum (CA) is marked by its thorny treatment and high recurrence rate. Although 5-aminolevulinic acid photodynamic therapy (ALA-PDT) demonstrates significant efficacy and safety in treating anal CA, it does not completely prevent recurrence. This study aimed to develop and validate a nomogram model in predicting the risk of relapse in HIV-negative patients with anal CA following treatment with ALA-PDT.
METHODS: A retrospective analysis was conducted on patients diagnosed with anal CA who received combined CO2 laser vaporization and ALA-PDT between January 2013 and May 2023. Patients were divided into recurrence and non-recurrence groups. A nomogram was developed based on factors showing statistical significance in multivariable logistic regression analysis. The discriminative ability and clinical utility of the nomogram were assessed via ROC curves and decision curve analysis, with internal validation performed through bootstrap resampling.
RESULTS: Among the 176 patients included, 33 (18.75 %) experienced recurrence, while 143 did not. Independent predictors for recurrence included HPV types, history of anal intercourse, and the number of CO2 laser treatments received. Incorporating these predictors, the nomogram demonstrated a superior diagnostic performance (area under the curve = 0.881, 95 % CI: 0.818-0.935) and a significant net benefit in decision curve analysis.
CONCLUSIONS: The nomogram accurately predicts the risk of recurrence in HIV-negative patients with anal CA following ALA-PDT. It offers a valuable tool for guiding preoperative clinical decision-making and establishing personalized treatment strategies to minimize the risk of relapse.

BACKGROUND: The objective was to investigate the correlation between Epstein-Barr virus (EBV) and human papillomavirus (HPV) infection in the development of benign thyroid lesions.
METHODS: 29 cases of Hashimoto\'s thyroiditis (HT), 133 cases of thyroid adenoma, and 34 cases of HT with thyroid adenoma paraffin embedded tissue samples were used for EBV and HPV quantitative detection.
RESULTS: None of the tissue samples carried HPV DNA. In HT tissue samples, the positive rate of EBV was 55.2% (16/29). In thyroid adenoma tissue samples, the positive rate was 37.6% (50/133). In HT combined with thyroid adenoma tissue samples, the positive rate of EBV was 67.6% (23/34). There was no correlation between EBV infection and clinical features such as age and gender.
CONCLUSIONS: The occurrence and development of benign thyroid lesions are closely related to EBV infection. HT combined with thyroid adenoma may be more susceptible to EBV infection than simple HT and thyroid adenoma, which provides a new idea for the diagnosis and treatment of benign thyroid lesions.

Despite the high effectiveness of HPV vaccines in preventing infection, vaccine hesitancy remains a concern, particularly in China. This study aimed to explore college students\' attitudes toward HPV vaccination and identify associated factors. Data was collected through a cross-sectional survey using self-administered questionnaires in four cities from May to June 2022. Chi-square tests and logistic regression analyses were conducted to identify factors. Additionally, an integrated structural equation model (SEM) based on the 3Cs (confidence, convenience, complacency) was developed to understand underlying factors contributing to hesitancy. The results from 2261 valid questionnaires were enlightening. A significant 89.47% (59.4% for females) considered HPV vaccination necessary, with 9.82% remaining neutral and only 0.71% deeming it unnecessary. Factors like higher education, being a medical student, residing in urban areas, having medical insurance, more extraordinary living expenses, a family history of tumors, and a solid understanding of HPV played a role in perceiving the vaccine as necessary. Among the 1438 female respondents, 84.36% had no hesitancy toward HPV vaccination, 13.53% expressed hesitancy, and 2.11% refused vaccination. Factors like age, understanding of HPV, medical staff recommendations, living expenses, and family history influenced hesitancy levels. SEM revealed that the 3Cs significantly affected vaccine hesitancy. Factors like price, booking process, vaccination times, trust in vaccines, medical staff recommendations, efficiency, and risk perception collectively influenced hesitancy. In conclusion, this study found high acceptance of HPV vaccination but acknowledged the complexity of hesitancy factors. It recommends medical staff disseminate scientific knowledge, offer recommendations, simplify booking procedures, and expand vaccination sites to address vaccine hesitancy effectively.

UNASSIGNED: To analyse the correlation between vaginal flora and cervical immune function of HPV-infected patients with cervical cancer.
UNASSIGNED: Six hundred females with genital tract infections treated in Xuzhou Hospital of Traditional Chinese Medicine from January 2014 to December 2016 were selected and divided into a high-risk HPV group (n=246) and a control group (n=354). The vaginal flora and human T lymphocyte subsets (CD3+, CD4+, CD8+) were detected. Multivariate logistic regression analysis was performed to explore the risk factors for HPV infection.
UNASSIGNED: The numbers of CD4+ and CD4+/CD8+ T cells of the high-risk HPV group were significantly lower than those of the control group (P<0.05). The two groups had similar numbers of CD3+ and CD8+ T cells. In the high-risk HPV group, the positive rates of Lactobacillus, Chlamydia trachomatis, Mycoplasma hominis, mycetes, Ureaplasma urealyticum and bacterial vaginosis were significantly higher than those of the control group (P<0.05). There was no significant difference in the positive rates of trichomonads between the two groups. Multivariate logistic regression analysis revealed that C. trachomatis and U. urealyticum were independent risk factors for high-risk HPV infection (P<0.05).
UNASSIGNED: High-risk HPV infection in patients with cervical cancer was associated with vaginal flora and immune function. C. trachomatis and U. urealyticum were independent risk factors for high-risk HPV infection.

BACKGROUND: Warts result from an infection with the human papilloma virus (HPV). Plantar warts, also known as Verruca plantaris, can be notably painful for the patient and possess contagious qualities, thus necessitating assertive treatment. Despite several available approaches for addressing plantar warts, efficacy remains elusive.
METHODS: One 22-year-old firefighter suffered from numerous plantar warts. After 26 days of traditional Chinese medicine soaking, the rashes completely disappeared. The treatment was without complications or discomfort, and a three-month follow-up showed no recurrence.
CONCLUSIONS: Our case investigation highlighted the efficacy of herbal soaking as a safe, painless, and non-invasive therapeutic option, positioning it as a potential avenue for managing multiple plantar warts.

Objectives: To study the prevalence and the association of HPV infection in retinoblastoma and to determine the most common genotype presented in RB. Methods: Following the PRIMSA guideline, 14 studies reporting HPV infection in RB acquired from six databases were included. Results: The prevalence of HPV from 941 RB samples was 15.6% [95% confidence interval (CI): 7.3-30]. Mexico followed by India and Brazil had the highest HPV prevalence in RB samples, 61.7% (95% CI: 17-93), 22.5% (95% CI: 9-47), and 12.1% (95% CI: 2-52), in order. HPV 16 was the most common genotype presented in RB samples 23% (95% CI: 9-47), followed by HPV 18 10% (95% CI: 3-30) and the combined HPV 16-18 6% (95% CI: 0-50). We did not find a significant association between HPV and RB [odds ratio (OR): 12.2; 95% CI: 0.65-232; p = 0.09]. However, after removing the largest-weighted study, a significant association between HPV and RB was observed (OR: 45.9; 95% CI; 8.6-245; p < 0.001). Conclusion: HPV prevalence in RB samples was 15% and HPV 16 was the most presented genotype in RB samples. There may be an association between HPV and RB that is needed to be confirmed by high quality future studies. Preventive and treatment measures against HPV infection are essential for the prevention of any possible consequences, in particular, RB.

Persistent high-risk human papilloma virus (HR-HPV) infection is the main risk factor for cervical cancer, threatening women\'s health. Despite growing prophylactic vaccination, annual cervical cancer cases are still increasing and show a trend of younger onset age. However, therapeutic approaches towards HPV infection are still limited. 25-hydrocholesterol (25HC) has a wide-spectrum inhibitory effect on a variety of viruses. To explore efficient interventions to restrict HPV infection at an early time, we applied different pseudoviruses (PsV) to evaluate anti-HPV efficacy of 25HC. We tested PsV inhibition by 25HC in cervical epithelial-derived HeLa and C-33A cells, using high-risk (HPV16, HPV18, HPV59), possibly carcinogenic (HPV73), and low-risk (HPV6) HPV PsVs. Then we established murine genital HPV PsV infection models and applied IVIS to evaluate anti-HPV efficacy of 25HC in vivo. Next, with the help of confocal imaging, we targeted 25HC activity at filopodia upon HPV exposure. After that, we used RNA-seq and Western blot analysis to investigate (1) how 25HC disturbs actin cytoskeleton remodeling during HPV infection and (2) how prenylation regulates the cytoskeletal remodeling signaling pathway. Our findings suggest that 25HC perturbs F-actin rearrangement by reducing small GTPase prenylation. In this way, the phenomenon of HPV virion surfing was restricted, leading to failed infection.

As global supply is still inadequate to address the worldwide requirements for HPV vaccines, we assessed the safety and immunogenicity of a new bivalent HPV16/18 vaccine. In this randomized, double-blind, placebo-controlled, phase 2 trial, healthy 9-45-year-old Chinese females in three age cohorts (600 aged 9-17 years; 240 aged 18-26 years; 360 aged 27-45 years) were randomized 1:1 to receive three doses (0,2,6 months) of HPV16/18 vaccine or placebo. We measured neutralizing antibodies against HPV 16 and 18 at 7 months and monitored safety to 12 months in all age cohorts; 9-17-year-old girls were monitored for safety and immunogenicity to 48 months. In vaccinees, 99.8% seroconverted for HPV 16 and 18 types at 7 months; respective GMTs of 5827 (95% CI: 5249, 6468) and 4223 (3785, 4713) were significantly (p < .001) higher than controls for all comparisons. GMTs in the 9-17-year-olds, which were significantly higher than in older women at 7 months, gradually declined to 48 months but remained higher than placebo with seropositivity rates maintained at 98.5% and 97.6% against HPV 16 and 18, respectively. Adverse events occurred at similar rates after vaccine and placebo (69.8% vs. 72.5%, p = .308), including solicited local reactions and systemic adverse events which were mainly mild-to-moderate. The bivalent HPV16/18 vaccine was well tolerated and induced high levels of neutralizing antibodies in all age groups which persisted at high levels to 48 months in the 9-17-year-old age group which would be the target for HPV vaccination campaigns.

If esophageal papilloma (EP) is a rare condition, esophageal papillomatosis (EPS) is a distinct rarity. To date, only 53 well documented cases have been described in English literature. However, the number of reports on EPS significantly increased to over 40 cases during the past 20 years. Perhaps, this is due to the broad use of endoscopy and related research achievements. Most of the cases are individual and it seems that there are no associations between them. And up to now no guidelines can be followed. To further understand this exceedingly rare disease, we had a comprehensive review of the epidemiology, etiology, clinical manifestations, pathogenesis, treatment, and clinical course of EPS.
