Human papillomavirus (HPV) is a preventable infection responsible for anogenital and oropharyngeal cancers, as well as genital warts. Two safe and effective vaccines are recommended for adolescents and young adults to protect against HPV infection. Both are severely underutilized. Sexual and ethnic minorities are disproportionately affected by HPV infection and its sequelae. The goals of this study were to (1) assess baseline differences in HPV-related awareness, knowledge, and attitudes between men and women, and (2) evaluate the differential efficacy of a brief, educational HPV intervention among ethnically and sexually diverse college students. Students attending undergraduate courses from 2015 to 2017 participated in a brief, tailored, classroom intervention designed to improve HPV-related awareness, knowledge, and attitudes. These outcomes were assessed immediately before and following an evidence-based educational presentation about HPV risks, outcomes, treatments, and prevention. At baseline, 84% of participants (N=386) had heard of HPV; 28% of men and 55% of women reported receiving ≥1 dose of HPV vaccine. Vaccinated women were seven times more likely to report favorable attitudes than unvaccinated women (RR=7.1, CI[3.3-15.5]). Hispanic participants had more positive attitudes toward HPV vaccination (62% vs. 44%; P=0.009) and were more willing to become vaccinated (66% vs. 46%; p=0.02) than non-Hispanic participants at baseline. Gay and bisexual men (92%) were more likely than heterosexual men (68%) to have heard of HPV, to receive any doses of HPV vaccine (37% vs 19%), to view HPV vaccination positively (58% vs 39%), and more willing to be vaccinated (86% vs 39%; P

This research project aims to examine the idea of stigma attached to cervical cancer in light of its association with HPV, a sexually transmitted infection (STI). The public recognition of this relationship appears to be increasing due to the current media attention surrounding HPV's causative role in the development of cervical cancer, and the newly-released HPV vaccine. Thus, this study explores the experiences and perceptions of cervical cancer patients and survivors living with this disease at a moment in time when it is becoming a very visible manifestation of a sexually transmitted infection, versus one identified historically as a life-threatening cancer. Disease-related stigma has vast individual, community, and societal repercussions: in the context of both cancer and sexually transmitted infections, it is broadly associated in the literature with decreased levels of screening, reluctance to seek treatment, decreased access to social support, economic discrimination, and major difficulties in implementing large-scale prevention efforts, such as contact tracing or name-based reporting. This study is premised on the belief that including the voices of patients and survivors themselves will provide a more holistic and complete understanding of the dimensions of cervical cancer-related stigma, which in turn will help to inform future educational and prevention messages tailored to reduce its impact. Additionally, it will illuminate the complexities and dynamics of how patients/survivors are able or unable to access social support-a first step in designing more effective and relevant support programs.

Measuring HPV exposure relies on detection of HPV type-specific antibodies, but methods are not standardized. Additionally, there is little information on the best sample type for HPV antibody detection. This study validated pseudovirion neutralization (PVN) assay for HPV antibody detection and compared it to IgG ELISA. Both assays were applied to paired serum and cervical mucus samples. Additionally, PVN assay was utilized to evaluate the feasibility of oral mucosal transudate (OMT) samples to monitor the HPV immune response. Serum was more likely to be positive on PVN assay than on IgG ELISA (p= 0.025). Both assays correlated with HPV-16 DNA status. HPV-18 PVN assay results correlated with HPV-18 DNA status. Few cervical mucus samples had detectable antibodies; no correlation with HPV DNA status was seen. OMT results were unsatisfactory. PVN assay was more sensitive than IgG ELISA; serum was a more reliable indicator of HPV-16/18 antibody status than cervical mucus.

Background: Cervical cancer is second most common cancer in women. The 15% incidence of cervical cancer in women worldwide can potentially be reduced by the vaccine against human papillomavirus (HPV). It is therefore important for all healthcare professionals including registered nurses to understand what affects women’s intentions and willingness to receive HPV vaccination so that they can overcome any inappropriate barriers and promote public health. Aim: The aim of this article was to describe factors influencing women’s intentions to obtain the HPV vaccine. Method: The following databases Cinahl, Medline, PsycINFO, Summon @ HKR and Pubmed were searched for articles that studied factors influencing women’s intention to obtain the HPV vaccine. Ten studies met the inclusion criteria, five qualitative and five quantitative. Results:  Four main categories were identified that influenced women’s intention to obtain the HPV vaccine: knowledge, attitudes, the influence of other people and the safety of the vaccine. Discussion: Better access for women to accurate information is the key to increase women’s intention to obtain the HPV vaccine and improving public health. Conclusion: Correct information about HPV and HPV virus is needed to increase women’s intention to obtain the vaccine. / Bakgrund: Cervixcancer är den näst vanligaste cancern hos kvinnor med en global incidens på15 %. Cervixcancer leder till hög mortalitet. Genom Humant Papillomvirus (HPV)-vaccinering kan incidensen minskas kraftigt. Vaccintäckningen är suboptimal på många plaster i världen. Det är viktigt att vårdpersonal, inklusive sjuksköterskor, förstår vilka faktorer som påverkar viljan och beslutet att vaccinera sig. På så sätt kan sjukvårdspersonal påverka dessa beslut och faktorer och därigenom öka vaccinationstäckningen i befolkningen. Syfte: Syftet var att beskriva faktorer som påverkar kvinnors avsikt till att vaccinera sig mot HPV. Metod: I denna allmänna litteraturstudie användes databaserna Cinahl, Medline, PsycINFO, Summon @ HKR and Pubmed för att söka efter artiklar som studerade faktorer som påverkar kvinnor att vaccinera sig mot HPV. Totalt tio artiklar inkluderades, fem kvalitativa och fem kvantitativa studier. Resultat: Fyra huvudkategorier identifierades som påverkade kvinnor att vaccinera sig mot HPV: Kunskap, attityder, andras inflytande och vaccinets säkerhet. Diskussion: Bättre tillgång till korrekt information för kvinnor om HPV-vaccinet är nyckeln till att öka kvinnors avsikt att vaccinera sig och på så sätt förbättra folkhälsan. Slutsats: Det krävs korrekt information om HPV virus och vaccin för att öka kvinnors avsikt till att vaccinera sig.

Background: Inhaled carbon monoxide (CO) appears to have beneficial effects on endotoxemia-induced impairment of hypoxic pulmonary vasoconstriction (HPV). This study aims to specify correct timing of CO application, it’s biochemical mechanisms and effects on inflammatory reactions. Methods: Mice (C57BL/6; n = 86) received lipopolysaccharide (LPS, 30 mg/kg) intraperitoneally and subsequently breathed 50 ppm CO continuously during defined intervals of 3, 6, 12 or 18 h. Two control groups received saline intraperitoneally and additionally either air or CO, and one control group received LPS but breathed air only. In an isolated lung perfusion model vasoconstrictor response to hypoxia (FiO2 = 0.01) was quantified by measurements of pulmonary artery pressure. Pulmonary capillary pressure was estimated by double occlusion technique. Further, inflammatory plasma cytokines and lung tissue mRNA of nitric-oxide-synthase-2 (NOS-2) and heme oxygenase-1 (HO-1) were measured. Results: HPV was impaired after LPS-challenge (p < 0.01). CO exposure restored HPV-responsiveness if administered continuously for full 18 h, for the first 6 h and if given in the interval between the 3rd and 6th hour after LPS-challenge (p < 0.05). Preserved HPV was attributable to recovered arterial resistance and associated with significant reduction in NOS-2 mRNA when compared to controls (p < 0.05). We found no effects on inflammatory plasma cytokines. Conclusion: Low-dose CO prevented LPS-induced impairment of HPV in a time-dependent manner, associated with a decreased NOS-2 expression.

Le taux de couverture vaccinale contre le papillomavirus humain (HPV) reste faible en France autour de 20%. Ce travail porte sur l’attitude adoptée par la population française afin de comprendre les motivations et les freins à la vaccination HPV.Une série d’études, qualitatives et quantitatives, a été réalisée en 2014-2016 sur deux populations, la première de jeunes filles de 15 à 25 ans et la deuxième de mères ayant des filles âgées de 11 à 16 ans. Notre approche méthodologique est essentiellement basée sur le modèle combiné issu de la théorie du comportement planifié (Theory of Planned Behavior, TPB, Ajzen, 1991) et du modèle des croyances relatives à la santé (Health Beliefs Model, HBM, Rosenstock, 1974). Parmi les modérateurs de la décision les deux systèmes de motivation décrits par Carver et White (1994) ont été retenus. En complément, une étude expérimentale a été conduite basée sur la Théorie des perspectives (Prospect Theory) de Kahneman et Tversky (1979). Les analyses statistiques ont été effectuées avec les logiciels R et SPSS. Plusieurs traitements statistiques ont été opérés sur les données : analyse des comparaisons, analyse en composantes principales (ACP), régressions linéaires multiples, ANCOVA etc.Les résultats apportent de nouveaux éclairages quant au processus de décision d’acceptation ou de refus de vaccination. Le modèle mis en évidence par ces études fait apparaître des facteurs caractéristiques tels que l'attitude favorable à la vaccination, la sécurité du vaccin, le contrôle perçu ainsi que le regret anticipé, qui jouent un rôle déterminant dans le processus de décision. L’environnement médical et familial proche jouent également un rôle essentiel. / The immunization coverage against HPV remains around 20%. The attitude of French girls was studied to understand the motivations and breaks to HPV.Several studies, qualitative and quantitative, were conducted in 2014-2016 on two populations, first sample of young women aged 15 to 25 years and second of mothers of girls aged 11 to 16. Our methodological approach is essentially based on the handset model from The Theory of Planned Behavior (TPB, Ajzen, 1991) and the Health Beliefs Model (HBM, Rosenstock, 1974). To find the moderators of making decision we opted for the two motivational systems described by Carver and White (1994). Finally, the experimental study we were inspired by the Prospect Theory of Kahneman and Tversky (1979). Statistical analyzes were performed using the softwares R and SPSS. Four types of treatment were carried out on the data: Analyze of comparisons (1); Principal Component Analysis (PCA) (2); Linear Regression to explain an intention to be vaccinated by some variables that allows us to make a prediction (3), and ANCOVA (4).The results provide new insights about the process of decision on vaccine acceptance. It appears that the favorable attitude to vaccination, the vaccine safety, the perceived control, and the anticipated regret play an important role in this decision process as well the doctor’s advice and family.

A infecção pelo Papilomavírus Humano (HPV) é a principal responsável pelo desenvolvimento de lesões intraepiteliais e, potencialmente, do câncer cervical (CC). A presença de fatores como inflamação e outros agentes infecciosos contribuem para a instalação e persistência do vírus. A inclusão da pesquisa do HPV e de outros agentes infecciosos relacionados junto a programas de rastreamento do CC ainda é controversa. Além disso, sabe-se que o processo inflamatório e as lesões celulares decorrentes da presença de HPV e seus cofatores provocam alterações na expressão de diversas proteínas, entre elas a S100A4, que poderia funcionar como biomarcador de exposição. Desta forma, foram analisadas amostras de esfregaços cervicais para investigação da relação do diagnóstico citológico com a presença de agentes infecciosos, além do padrão de expressão da proteína S100A4. Nossos resultados demonstraram que o aparecimento de lesões ou atipias citológicas apresentou associação com a presença de HPV, tanto na infecção simples como na infecção por múltiplos genótipos de alto risco oncogênico, sugerindo a pesquisa molecular do HPV complementar à citologia. A presença de infecção latente pelo HPV também foi observada, a qual deve ser acompanhada com exames citológicos periódicos. A infecção por Chlamydia trachomatis desempenha importante papel como cofator para o desenvolvimento do CC e foi prevalente na população estudada, demonstrando associação com a presença de diferentes genótipos de HPV. Tanto nas pacientes sintomáticas como nas assintomáticas houve a detecção de leveduras do gênero Candida, sendo que a mais prevalente foi a C. albicans apresentando-se sensível à Anidulafungina e Anfotericina B, na maioria dos casos, e resistente ao Fluconazol. Com relação à expressão da proteína S100A4, houve associação com as alterações citológicas características do HPV, nas quais houve redução de sua expressão à medida que aumentou o grau da lesão. No entanto, também observamos que há expressão fisiológica da proteína S100A4 no epitélio escamoso estratificado da ectocérvice que varia de acordo com o grau de maturação celular e a presença de alterações citológicas inflamatórias, onde foi demonstrado aumento da sua expressão. Portanto, a avaliação da expressão da proteína S100A4 pode auxiliar no diagnóstico precoce do câncer de colo do útero nas lesões intraepiteliais cervicais positivas para HPV. Analisando-se globalmente, estes resultados sugerem a inclusão da pesquisa molecular de HPV e C. trachomatis, bem como a identificação de leveduras do gênero Candida complementares à citologia esfoliativa junto a programas de rastreamento. Além disso, a proteína S100A4, mostrou-se promissora como biomarcador dos efeitos celulares dos fatores associados. Observa-se que a associação de diferentes metodologias permite a detecção precoce de lesões e, consequentemente, contribuem para a redução da incidência do CC. / Human papillomavirus (HPV) infection is the main responsible for the development of intraepithelial lesions and potentially cervical cancer (CC). The presence of factors such as inflammation and other infectious agents contribute to the onset and persistence of the virus. The inclusion of HPV research and other infectious agents associated in the CC screening programs is still controversial. In addition, it is known that inflammation and cell injury caused by the presence of HPV and their cofactors cause changes in gene expression and function of several proteins, including the S100A4 which could function as a biomarker of exposure. Thereby, samples of cervical specimens were analyzed to investigate the relationship of cytological diagnosis in the presence of infectious agents, other than the standard expression of S100A4 protein. Our results demonstrated that the development of lesions or cytological atypia was associated with the presence of HPV in either simple infection or infection by multiple genotypes of high oncogenic risk, indicating the importance of molecular HPV analysis complementary to cytology. The presence of latent infection was also observed and must be monitored with periodic cytological examinations. The Chlamydia trachomatis infection plays an important role as a cofactor for the development of CC and was prevalent in the population studied, demonstrating association with the presence of different HPV genotypes. For both symptomatic and asymptomatic patients there was a yeast detection of Candida, and the most prevalent was the Candida albicans presenting sensitive to Anidulafungin and Amphotericin B, in most cases, and resistant Fluconazole. Regarding the S100A4 protein expression, there was association with abnormal cytological HPV characteristics where a reduction of expression could be observed and the degree of injury increased. However, we also observed that there are physiological expression of S100A4 protein in the stratified squamous epithelium of the ectocervix and this varies according to the degree of cell maturation and the presence of inflammatory cell alterations, increased expression where demonstrated. Therefore, the evaluation of the expression of S100A4 protein may assist in the early diagnosis of cervical cancer in cervical intraepithelial lesions positive for HPV. Overall, these results suggest the inclusion of molecular research of HPV and C. trachomatis, and the identification of yeasts Candida complementary to exfoliative cytology in screening programs. In addition, the S100A4 protein has shown to be promising as a biomarker for cellular effects of associated factors. It was observed that the association of different methodologies allows early detection of lesions and therefore contribute to reducing the incidence of CC.

African Americans have higher rates of HPV-related cancer incidence than other ethnicities. A review of 18 studies completed on African Americans and people of African descent was done. African Americans do, in fact have higher rates of HPV-related cancer than other racial groups. The disparity appears to be decreasing over time with increased distribution of knowledge about the human papillomavirus to African American groups. However, studies show that many African American communities lack essential knowledge about the severity of HPV-related cancer, HPV transmission and commonality, and the HPV vaccine itself.

Background: The HPV vaccine has been introduced to the public and the medical community since June 2006 for the vaccination of females and since November 2009 for the vaccination of males ages 9-26 years old. The purposes of this research were to explore multiple factors and relationships among Health Belief Model (HBM) constructs (perceived susceptibility, perceived severity, perceived barriers, and perceived benefits) and mediating factors (self-efficacy and cues to action) related to HPV, HPV-associated diseases, and HPV vaccine among Russian college students and to determine which factors were most important when considering who would/would not seek HPV vaccination. Methods: A quantitative, cross-sectional, descriptive, and correlational survey design was used in this study. An existing self-report questionnaire HPV Study Survey was adapted with the permission from the author. One thousand two hundred participants were contacted by Yaroslav-the-Wise Novgorod State University, Veliky Novgorod, Russia registrar's office through e-mails and messaging using two social networks through simple random sampling method using the SQL statement "ORDER BY NEWID" propriety of Microsoft algorithm out of the total student population (9,923 students). The survey was distributed through SurveyMonkeyTM survey software that was activated December 2011 - April 2012. Results: Two hundred seventy students replied to the survey (22.5% response rate) and 117 participants fully completed it out of 270 who responded to the survey (43.33% completion rate). The initial response rate increased 4.4 times using social networks messaging compared to e-mailing invitations. Overall, average knowledge levels were moderate. Participants' behaviors regarding their sexual activity showed that the majority of participants were sexually active. Participants' perceptions (susceptibility, severity, barriers, and benefits) and mediating factors (cues to action and self-efficacy) were moderate. Participants' behavioral intention to get HPV vaccination was moderate. There were statistically significant differences between males and females in perceived susceptibility, perceived barriers, self-efficacy, behavioral intention, and in three behavioral items (having had sexual contact; age of having had sexual contact and sex for the first time). Sixty percent of the variance in behavioral intention getting HPV vaccination could be explained by two HBM constructs (perceived benefits and self-efficacy). Self-efficacy was the number one predictor of behavioral intention (p < 0.001) and perceived benefits were the number two predictor of behavioral intention (p < 0.01).
