High-risk human papillomaviruses (HPVs) are known to be associated with different anogenital cancers including cervical, anal, penile, and vaginal cancers. They are also found to be responsible for the dramatic increases in oropharyngeal squamous cell carcinoma (OPSCC) observed in the United States and Europe. The model for how high-risk HPVs induce cancer formation comes from studies of cervical cancer which usually involves integration of the HPV into the human genome and subsequent changes due to induced chromosomal instability. Recent work, discussed here, however suggests that this model may not be completely correct. In addition, we summarize studies now done in OPSCC which demonstrate that the role of HPV in these cancers may be different from that in cervical cancer. Finally, we propose new models for how HPV may be involved in the formation of these 2 cancers.

Epstein–Barr virus (EBV) has been recently shown to be co-present with high-risk human papillomaviruses (HPVs) in human cervical cancer; thus, these oncoviruses play an important role in the initiation and/or progression of this cancer. Accordingly, our group has recently viewed the presence and genotyping distribution of high-risk HPVs in cervical cancer in Syrian women; our data pointed out that HPVs are present in 95.45% of our samples. Herein, we aim to explore the co-prevalence of EBV and high-risk HPVs in 44 cervical cancer tissues from Syrian women using polymerase chain reaction (PCR), immunohistochemistry (IHC) and tissue microarray (TMA) analyses. We found that EBV and high-risk HPVs are co-present in 15/44 (34%) of the samples. Additionally, we report that the co-expression of LMP1 and E6 genes of EBV and high-risk HPVs, respectively, is associated with poorly differentiated squamous cell carcinomas phenotype; this is accompanied by a strong and diffused Id-1 overexpression, which is an important regulator of cell invasion and metastasis. These data imply that EBV and HPVs are co-present in cervical cancer in the Middle East area including Syria and their co-presence is associated with a more aggressive cancer phenotype. Future investigations are needed to elucidate the exact role of EBV and HPVs cooperation in cervical carcinogenesis.

Context Cervical cancer affects 12 000 women in the United States annually. However, despite its prevalence, there remains no good methodology to detect its recurrence. Objective To identify the role of cervicovaginal high-risk human papilloma virus (hr-HPV) testing in predicting cervical cancer recurrence. Design This is a retrospective study of patients who underwent hr-HPV testing as part of their routine surveillance for cervical cancer. Standard statistical analyses, including χ2 test and multivariable logistic regression, were performed with IBM SPSS 19.0. Results A total of 133 patients were identified, of whom 107 (80%) had squamous cell carcinoma. Ninety patients (68%) had bulky disease and were treated primarily with chemoradiation and brachytherapy. Of patients whose disease recurred, 5 patients (42%) had tested positive for hr-HPV during their surveillance period, compared to 13 patients (11%) for whom disease did not recur (relative risk: 3.88, P = .002). On multivariate logistic regression, hr-HPV status remained significantly predictive of disease recurrence (odds ratio: 12.3, P = .02, 95% confidence interval: 1.5–99.6). Using 2 × 2 table analysis, we found that while cervicovaginal cytology has limited specificity (5.7%) in predicting recurrence, the combination of cytology with hr-HPV testing increases the specificity of testing to 89.3%. Conclusions Persistence of hr-HPV is a risk factor for disease recurrence. High-risk–HPV testing is not routinely used during surveillance for cervical cancer, but this study suggests that large, prospective trials investigating the role of hr-HPV testing in cervical cancer surveillance are needed.

Cervical cancer is responsible for around 5% of all human cancers worldwide. It develops almost exclusively from an unsolved, persistent infection of the squamocolumnar transformation zone between the endo- and ecto-cervix with various high-risk (HR) human papillomaviruses (HPVs). The decisive turning point on the way to persistent HPV infection and malignant transformation is an immune system weakened by pathobionts and oxidative stress and an injury to the cervical mucosa, often caused by sexual activities. Through these injury and healing processes, HPV viruses, hijacking activated keratinocytes, move into the basal layers of the cervical epithelium and then continue their development towards the distal prickle cell layer (Stratum spinosum). The microbial microenvironment of the cervical tissue determines the tissue homeostasis and the integrity of the protective mucous layer through the maintenance of a healthy immune and metabolic signalling. Pathological microorganisms and the resulting dysbiosis disturb this signalling. Thus, pathological inflammatory reactions occur, which manifest the HPV infection. About 90% of all women contract an HPV infection in the course of their lives. In about 10% of cases, the virus persists and cervical intra-epithelial neoplasia (CIN) develops. Approximately 1% of women with a high-risk HPV infection incur a cervical carcinoma after 10 to 20 years. In this non-systematic review article, we summarise how the sexually and microbial mediated pathogenesis of the cervix proceeds through aberrant immune and metabolism signalling via CIN to cervical carcinoma. We show how both the virus and the cancer benefit from the same changes in the immune and metabolic environment.

ObjectiveTo examine trends and outcomes related to adjuvant systemic chemotherapy alone for high risk, early stage cervical cancer.MethodsThis retrospective observational study queried the National Cancer Institute’s Surveillance, Epidemiology, and End Results Program from 2000 to 2016. Surgically treated women with American Joint Commission on Cancer stages T1–2 cervical cancer who had high risk factors (nodal metastasis and/or parametrial invasion) and received additional therapy were examined. Propensity score inverse probability of treatment weighting was used to assess the survival estimates for systemic chemotherapy versus external beam radiotherapy with chemotherapy.ResultsAmong 2462 patients with high risk factors, 185 (7.5%) received systemic chemotherapy without external beam radiotherapy, of which the utilization significantly increased over time in multivariable analysis (adjusted odds ratio per 1 year increment 1.06, 95% confidence interval (CI) 1.02 to 1.09). In weighted models, adjuvant chemotherapy and combination therapy (external beam radiotherapy and chemotherapy) had comparable overall survival among patients aged <40 years (hazard ratio (HR) 0.73, 95% CI 0.41 to 1.33), in adenocarcinoma or adenosquamous histologies (HR 0.90, 95% CI 0.62 to 1.32), and in those with nodal metastasis alone without parametrial tumor invasion (HR 1.17, 95% CI 0.84 to 1.62). In contrast, systemic chemotherapy alone was associated with increased all cause mortality compared with combination therapy in patients aged ≥40 years (HR 1.57, 95% CI 1.19 to 2.06), with squamous histology (HR 1.63, 95% CI 1.19 to 2.22), and with parametrial invasion alone (HR 1.87, 95% CI 1.09 to 3.20) or parametrial invasion with nodal metastasis (HR 1.64, 95% CI 1.06 to 2.52).ConclusionUtilization of adjuvant systemic chemotherapy alone for high risk, early stage cervical cancer is increasing in the United States in the recent years. Our study suggests that survival effects of adjuvant systemic chemotherapy may vary based on patient and tumor factors. External beam radiotherapy with chemotherapy remains the standard for high risk, early stage cervical cancer, and use of adjuvant systemic chemotherapy without external beam radiotherapy should be considered with caution.

Background: High-risk oncogenic human papillomaviruses (HPV) are the cause of sexually transmitted viral infection. Its persistence is a risk factor for precancerous lesions of the cervix, which will constitute the base of cervical cancer. In the world, the prevalence of high-risk oncogenic HPV is 66.7%, which is higher among women starting their sexual activity.Methods: An analytical cross-sectional study was conducted in high schools in Gabon regarding parents. The variables selected were the socio-cultural and demographic characteristics of the parents, their knowledge of human papillomavirus vaccination and their acceptability of HPV vaccination and finally the feasibility of HPV vaccination. The statistical test used was Pearson's Chi-square, and a difference was considered significant for p<0.05.Results: The majority of parents, 89%, were informed of the existence of cervical cancer. However, 73.4% of them were unaware of the existence of vaccination against cervical cancer. Only 2.4% of parents had vaccinated their daughters against cervical cancer at the time of the study. These parents only 53.4% expressed an interest in vaccinating their daughters in 53.4% of cases. The ability to vaccinate children is associated with the socio-professional status of parents (p˂0.000).Conclusions: The majority of parents approved school-based vaccination against human papillomavirus infections despite its reported cost and lack of information. The integration of anti-HPV vaccination into the expanded programme on immunization in Gabon will improve immunization coverage.

Role Of Religion

Abstract The history of American public education has generally been considered as a steady transition from religious and sectarian to secular and pluralist, with the role of science in education increasing as the role of religion decreased. This article examines a conception of the role of religion in education that does not fit this narrative, the “social religion” of theorists of moral and character education in the 1920s. Relying on ideas of religious naturalism and with an orientation toward the practical effects of religious belief, this community of scholars asserted a concept of religion that would allow it to be at the heart of the common school project, uniting all under the common morality of the social good. Influenced both by liberal Protestant humanism and the scientific worldview pervasive in education reform at the time, these character educationists’ ideas remind us of the historical contingency of categories like “religious” and of the antiquity of ideas we might classify under the heading of spirituality in American culture.

The association between high-risk genotypes of human papillomavirus (hr-HPV) and cervical cancer is well established. As hr-HPV testing is rapidly becoming a part of routine cervical cancer screening, either in conjunction with cytology or as primary testing, the management of hr-HPV-positive women has to be tailored in a way that increases the detection of cervical abnormalities while decreasing unnecessary colposcopic biopsies or other invasive procedures. In this review, we discuss the overall utility and strategies of hr-HPV testing, as well as the advantages and limitations of potential triage strategies for hr-HPV-positive women, including HPV genotyping, p16/Ki-67 dual staining, and methylation assays.

PURPOSE High-risk human papillomaviruses (hrHPV) are the primary cause of cervical cancer. Human papillomavirus (HPV) vaccination is expected to prevent cervical cancers caused by the HPV types included in vaccines and possibly by cross-protection from other types. This study sought to determine the hrHPV type distribution in women at a rural Zimbabwe hospital. METHODS We implemented a cross-sectional study at the Karanda Mission Hospital. Using the Visual Inspection with Acetic Acid Cervicography technique, clinicians collected cervical swabs from 400 women presenting for screening for cervical cancer. Samples were initially analyzed by Cepheid GeneXpert; candidate hrHPV genotypes were further characterized using the Anyplex II HPV28 Detection Kit. RESULTS Twenty-one percent of the 400 women were positive for a high-risk genotype when using the GeneXpert analyzer; 17% were positive when using the multiplex analysis. Almost two thirds of the hrHPV women had a single DNA type identified, whereas one third had multiple genotypes, ranging from 2 to 5. hrHPV was observed more frequently in HIV-positive than in HIV-negative women (27% v 15%). Of the 113 isolates obtained, 77% were hrHPV genotypes not included in the bivalent or quadrivalent vaccines, and 47% represented DNA types not covered in the nonavalent vaccine. Forty-seven percent of the women with hrHPV harbored a single genotype that was not covered by the nonavalent vaccine. CONCLUSION A large fraction of hrHPV isolates from women participating in a cervical cancer screening program in northern Zimbabwe are DNA types not covered by the bivalent, quadrivalent, or nonavalent vaccines. These findings suggest the importance of characterizing the hrHPV DNA types isolated from cervical neoplasia in this population and determining whether cross-immunization against these genotypes develops after administration of the vaccines in current use.
