BACKGROUND: Young men can be difficult to engage in health research using traditional methods of recruitment. Social networking sites are increasingly being used to recruit participants into health research, due to their cost effectiveness, overall generalizability, and wide reach. OBJECTIVE: The aim of this study was to determine the feasibility of using Facebook to recruit young Australian men into a human papillomavirus (HPV) prevalence study. METHODS: We recruited male permanent residents of Australia, aged 18 to 35 years, into the HPV in Young Males (HYM) study through targeted advertising placed on Facebook...

To be effective, therapeutic cancer vaccines should stimulate both an effective cell-mediated and a robust cytotoxic CD8+ T-cell response against human papillomavirus (HPV)-infected cells to treat the pre-existing tumors and prevent potential future tumors. In this study, the therapeutic experiments were designed in order to evaluate antitumor effect against the syngeneic TC-1 tumor model. The anti-tumor efficacy of a HPV-16 E7 DNA vaccine adjuvanted with melatonin (MLT) was evaluated in a C57BL/6 mouse tumor model by measuring tumor growth post vaccination and the survival rate of tumor-bearing mice, analyzing the specific lymphocyte proliferation responses in control and vaccinated mice by MTT assay...

PURPOSE: Human papillomavirus is found in adults and adolescents and is associated with genital warts and cervical cancer. However, it has been detected in girls younger than 10 years old. Currently, there are no prevention methods for this age group, since it is not considered a risk group. The aim of this study was to evaluate the presence of infection and HPV subtype in girls under 9 years old attended at a referral service in the State of Espírito Santo, Brazil. METHODS: Forty-three girls younger than 9 years old had gynecological brush samples collected from vulval and perineal/anal regions...

PURPOSE: Despite improvement in vaccines against human papilloma virus (HPV), the causative agent of cervical cancer, screening women for cervical precancer will remain indispensable in the coming 30-40 years. A simple test that could be performed at home or at a doctor's practice and that informs the woman whether she is at risk would significantly help make a broader group of patients who aware that they need medical treatment. Cervical vaginal fluid (CVF) is a body fluid that is very well suited for such a test...

BACKGROUND: The most recent (2012) worldwide estimates from International Agency for Research on Cancer indicate that approximately 528,000 new cases and 270,000 deaths per year are attributed to cervical cancer worldwide. The disease is preventable with HPV vaccination and with early detection and treatment of pre-invasive cervical intraepithelial neoplasia, CIN. Antibodies (Abs) to HPV proteins are under investigation as potential biomarkers for early detection. METHODS: To detect circulating HPV-specific IgG Abs, we developed programmable protein arrays (NAPPA) that display the proteomes of two low-risk HPV types (HPV6 and 11) and ten oncogenic high-risk HPV types (HPV16, 18, 31, 33, 35, 39, 45, 51, 52 and 58)...

Human papillomavirus (HPV) vaccine is efficacious but the real-life effectiveness of gender-neutral and girls-only vaccination strategies is unknown. We report a community-randomized trial on the protective effectiveness [(PE) = vaccine efficacy (VE) + herd effect (HE)] of the two strategies among females in virtually HPV vaccination naïve population. We randomized 33 Finnish communities into Arm A) gender-neutral vaccination with AS04-adjuvanted HPV16/18 vaccine (11 communities), Arm B) HPV vaccination of girls and hepatitis B-virus (HBV) vaccination of boys (11 communities) or Arm C) gender-neutral HBV vaccination (11 communities)...

Human papillomavirus (HPV) infection is associated with several cancers such as cancer in the cervix, vagina, and vulva and oropharyngeal, anal, penile, and cutaneous carcinomas, which is regarded as a great public health concern. The association between HPV is the strongest with cervical cancer because almost all such malignancies contain viral DNA, notably HPV types 16 and 18. The present chapter summarizes recent progresses of the HPV-associated cancers regarding epidemiology, molecular biology, HPV testing, vaccination, and treatment of HPV-related cancers...

BACKGROUND: It is estimated that a total of 120,000 new cancer cases in men and in women in more developed countries could be avoided if exposure to HPV was prevented. We used the nationwide pool of German population-based cancer registry data to estimate the burden of HPV-attributable cancer in this population for the year 2013. METHODS: Incident cases of cervical cancer, squamous cell carcinoma of the anus, oropharynx (OP), as well as of the vulva, vagina and penis were classified as potentially HPV-associated and identified from the nationwide cancer registry data-pool...

HPV is the sexually transmitted agent most common among young people, like college students. The aim of study was to associate sexual behavior characteristics of women with HPV, detected in genital samples taken before the introduction of the HPV vaccine. Female students during 2001-2005 donated genital samples and the samples were re-analyzed in 2013 for HPV genotyping by RT-PCR. The frozen storage of the students' genital samples allowed the detection of HPV DNA and its genotyping after years of sample collection...

Human papillomavirus (HPV) is a small double-stranded DNA virus that commonly infects humans. The oncogenic characteristics of HPV derive from the oncoproteins E6 and E7 that act inhibiting p53 and pRB tumor suppressors. About 5% of all cancers worldwide are attributable mainly to those known as high-risk, including HPV types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, and 59. Infection with HPV is common after sexual initiation, but the majority of HPV infections do not cause symptoms or disease and are cleared within 12-24 months post-infection...

Human papillomavirus (HPV) is considered the most important risk factor for the development of ano-genital region cancer in both women and men. Whereas low-risk genotypes are responsible for cutaneous and genital lesions, high-risk genotypes are associated with ano-genital cancer. The aim of this study was to retrospectively analyse the prevalence, genotype distribution and temporal dynamics of HPV infection in 2312 specimens from 2312 subjects (2149 women and 163 men) who attended the laboratory of molecular biology, UOC Microbiology and Virology, Azienda Ospedaliera-Universitaria, Policlinico of Bari, Italy...

High-risk human papillomavirus (hrHPV) has been identified as a key factor in the development of cervical cancer. Integration of viral DNA into the host genome has been postulated as an important etiological event during cervical carcinogenesis. High-risk HPV DNA integration frequently results in either the deletion or interruption of the large fragment of E1 and E2 region and the overexpression of oncogenes E6 and E7 in the viral genome, and the activation of oncogenes and the inactivation of tumor suppressors in host genome...

Background: Human papillomavirus (HPV) vaccine was recommended in 2006 for routine vaccination of US females aged 11-12 years. Most vaccine used through 2014 was quadrivalent vaccine (4vHPV), which prevents HPV-6, -11, -16, and -18 infection. To evaluate vaccine impact, we measured HPV prevalence in the National Health and Nutrition Examination Survey (NHANES). Methods: We analyzed HPV DNA types detected in self-collected cervicovaginal specimens and demographic, sexual behavior, and self-reported vaccination data from females 14-34 years old...
