A study on the cognitive status of human papillomavirus among adult males in Tianjin based on the health belief model

Background:To understand the health beliefs and knowledge of human papillomavirus among adult males in Tianjin.Methods:An online questionnaire survey was conducted from 18 January 2023 to 6 March 2023 using snowball sampling method.Analyze the health belief scores and human papillomavirus(HPV)and HPV vaccine knowledge scores of adult males in Tianjin,and analyze their influencing factors.Results:A total of 388 adult males in Tianjin were surveyed,with an average total score of 3.23±0.04 for their health beliefs.Among them,the average scores for perceived severity,perceived susceptibility,perceived impairment,perceived benefit,and self-efficacy were 3.41±1.05,2.37±1.20,2.96±1.00,3.51±0.90,and 3.36±1.08,respectively.Multiple linear regression analyses showed education was a factor influencing health beliefs.The average total score of knowledge is 64.09±15.62,with 277 people scoring above 60,and a pass rate of 71.4%.Through multiple linear regression analysis,education level,emotional status,whether disease testing has been done,and whether family and friends have been diagnosed with HPV positive are the main influencing factors.Conclusion:The awareness rate of HPV among adult males in Tianjin is still acceptable,but there are still misconceptions.The overall level of health beliefs is moderate,and the perceived susceptibility level is low.It is necessary to strengthen health education on HPV related knowledge for males and improve their cognitive level.

Study on the Correlation between Human Papillomavirus and Mycoplasma genitalium Combined with TCT Detection

Objective: This study aims to explore the correlation between human papillomavirus (HPV) and Mycoplasma genitalium (CT) combined with TCT detection in cervical cancer screening. Method: A cross-sectional study design was adopted, and a total of 609 women who came to seek medical treatment were recruited as the study subjects. Combination testing was evaluated on cervical cancer screening by testing the women for HPV, CT with TCT detection and analyzing the relationship of cervical lesions with HPV and CT infection. Results: The study results showed that 21.57% of the subjects were infected with both HPV and CT, and 48.42% of the cases had abnormal TCT results at the same time. Further data analysis showed that HPV infection was significantly associated with abnormal TCT outcomes (p < 0.05), suggesting a possible synergistic effect of the two infections in cervical lesions. The combined sensitivity and specificity of HPV, CT and TCT detection were 21.57% and 48.42%, respectively, which were significantly higher than that of single detection. Conclusion: In summary, the results of this study support the importance of combined HPV, CT, and TCT testing in cervical cancer screening, and propose the hypothesis that combined testing may improve screening effectiveness. However, further large sample studies are needed to confirm this conclusion and explore the prospects of combined testing in clinical practice.

Evaluating the Association between Human Papillomavirus and Vulvar Cancer:A Comprehensive Analysis Using Bradford Hill Criteria

Background:The role of human papillomavirus(HPV)in the development of vulvar cancer(VC)has been widely studied,but findings have been inconsistent.Despite numerous meta-analyses exploring the potential link between HPV and VC,the association remains controversial due to inherent limitations in meta-analytic methods.Objectives:To address this controversy,the study aims to investigate the potential link between HPV and VC using the Bradford Hill criteria,which offer a more comprehensive framework for establishing causation.Methodology:The study began by extracting all relevant studies on the association between HPV and VC from the PubMed database.The potential links were then assessed by examining the data using the major postulates of the Bradford Hill criteria.To ensure the reliability of the findings,the methodologies of the identified studies were critically evaluated to account for possible false-negative and false-positive results.Results:The assessment of previous studies against the Bradford Hill criteria revealed that the major postulates were not fulfilled.Conclusion:Based on the findings,it can concluded that there is no causal association between HPV and VC.

Safety and immunogenicity of human papillomavirus-16/18 AS04-adjuvanted vaccine in healthy Chinese females aged 15 to 45 years:a phase Ⅰ trial

Globally,about 70% of cervical cancers are associated with human papillomavirus (HPV)-16 or HPV-18 infection.A meta-analysis of epidemiologic studies in China showed that HPV was present in 98% of cervical cancer samples.The HPV-16/18 AS04-adjuvanted vaccine Cervarix has shown a high level of protection against HPV-16/18 infections and associated cervical lesions.This phase Ⅰ trial (NCT00549900) assessed the safety,tolerability,and immunogenicity of the vaccine in Chinese.Thirty healthy Chinese females,aged 15 to 45 years with a median age of 29.5 years,received three doses of Cervarix in Months 0,1,and 6.Safety was assessed via recording solicited local and systemic symptoms within 7 days and unsolicited symptoms within 30 days after each vaccination.Serious adverse events,new onset of chronic diseases,and other medically significant conditions were recorded throughout this trial.As an exploratory objective,HPV-16/18 antibody titers were determined by enzyme-linked immunosorbent assay in serum samples collected in Months 0 and 7.Pain at the injection site was the most frequently reported local symptom.Two subjects reported medically significant adverse events.Both cases were assessed as unrelated to vaccination by the investigator.In Month 7,100% seroconversion was observed for both anti-HPV-16 and anti-HPV-18 with high geometric mean antibody titers.HPV-16/18 AS04-adjuvanted vaccine,evaluated for the first time in Chinese females,was generally well tolerated and immunogenic,as previously shown in global studies.

Monoarthropathy or Polyarthritis in Adolescent Japanese Girls Who Received Immunization with the Human Papillomavirus Vaccine

Joint pain or arthralgia is a common complaint among girls who have received immunization with the human papillomavirus (HPV) vaccine, but the pathogenesis of this disorder has not been completely understood. We report 2 cases of joint lesions after HPV vaccination. In one case, a 13-year-old patient showed transient arthropathy in the right wrist joint after the first dose of Gardasil® administered in her left shoulder. In the other case, an 18-year-old patient had migrating joint pain with redness and swelling after the third dose of Cervarix®. Her serum C-reactive protein and anti-MMP-3 levels were slightly elevated, but no autoantibodies, including rheumatoid factor and anti-CCP antibody, were detected. Although various nonsteroidal anti-inflammatory drugs produced no relief, small doses of both tacrolimus and prednisolone were highly effective for her polyarthritis. The development of reactive joint lesions after HPV vaccination was noteworthy.

PRELIMINARY STUDY OF A NOVEL HUMAN PAPILLOMAVIRUS TYPE 16 L1/E6-E7 CHIMERIC RECOMBINANT DNA VACCINE

Objective Preparations of HPV16 L1/E6 and L1/E7 prophylactic and therapeutic DNA vaccines. Methods The nucleotides within HPV16 E6 and E7 genes, which are responsible for viral transforming activity, were mutated by mage primer site-directed mutagenesis method. The correctly mutated E6 and E7 fragments were separately cloned into an eukaryotic expression vector pVAX1, together with HPV16 L1 gene, generating chimeric recombinants plasmids 1MpVAX1-L1E6, 2MpVAX1-L1E6, 1MpVAX1-L1E7, 2MpVAX1-L1E7 and 3MpVAX1-L1E7. CHO cells were transiently transfected with the individual DNA vaccines by calcium phosphate method. Target protein expressions in the extracts of the transfected cell lines were measured by ELISA and immunohistochemistry, with HPV16 L1 and E6 specific monoclonal antibodies. Results ELISA assays showed the P/N ratios in the cell extracts transfected with L1E6 and L1E7 plasmids were more than 2.1. Immunohistochemistry revealed brownish precipitant signal in cytoplasm and nuclei of the transfected cells. Conclusion Successful constructions of prophylactic and therapeutic DNA vaccine plasmids lay solid foundation for future animal experiment and clinical trial.

Awareness and knowledge of human papillomavirus vaccination and their influential factors among Chinese women: a systematic review

Objectives: To systematically review the knowledge attitudes and the influential factors on human papillomavirus(HPV) vaccination among Chinese women.Methods: Published studies on knowledge and attitudes of HPV vaccination for preventing cervical cancer among Chinese female population were retrieved using the major Chinese and English databases. Meanwhile, handwork retrieval was also conducted and the references including in the literature were retrieved. The quality of the literature was rigorously evaluated and extracted independently by two researchers and the data were analyzed and described by review manager 5.3(RevMan5.3) software.Results: In all, 19 articles including 8 articles in Chinese and 11 in English were chosen. A total of 30,176 participants were included and the sample size ranged from 64 to 6,024. The overall awareness of HPV and HPV vaccine among Chinese women was at a low level. Chinese women generally showed poor knowledge about HPV and HPV vaccine. Acceptance of HPV vaccination among Chinese women was at a high level. Vaccination intentions were influenced by the theory of planned behavior(TPB) and measured by attitudes subjective norms and perceived behavioral control.Conclusions: The health authorities may evaluate and develop TPB-based interventions to increase HPV vaccination intentions of Chinese women. HPV vaccination programs should focus on carrying out multi-level and targeted health education and developing effective public health strategies after balancing the cost and benefit of HPV vaccine program. Medical staff should play the positive role in promoting the use of HPV vaccines in China. Integration of policy and community perspectives and multi-level interventions are essential to maximize the public health benefits of HPV vaccination.

SEARCH FOR HERPES SIMPLEX VIRUS TYPE2（HSV－2）AND HUMAN PAPILLOMAVIRUS（HPV）IN THE NORMAL AND ABNORMAL CERVICAL SAMPLES

The specimens of 111 cervical carcinomas. 68 chronic cervicitis and 43 normal cervical exfoliated epithelial cells were examined for the presence of HSV2 DNA sequences with DNA hybridization using HSV2 BgL Ⅱ N fragment probe labelled by 32PdCTP. The result showed that the infection rates of HSV2 in the samples of cervical cancer.chronic cervicitis and normal epithelial cells were 1 4. 41 %(16/111). 27.94%( 19/68) and 25.58% ( 11/43),respectively. It was implied that early stages carcinogenesis of cervical epithelial cells might be correlated with the HSV2 infection.Sixteen HSV 2 positive samples of cervical carcinomas were also examined for the presence of the sequences homologous to human papillomavirus (HPV) type 6B/11. 16 and 18 DNA using dot blot hybridization (Tm17℃). The result indicated that 13 out of 16 were HPV 16 DNA hybridization positive accounting for 81. 2% of all HSV-2 positive samples and none of them were positive for HPV type 6B/11 and 18. The result indicated that double infection of HSV 2 and HPV16 in the same cervical carcinoma tissues may provide a strong evidence of the viral synergistic interaction in the induction of female cervical

A Case with XXXX Syndrome Who Was Incidentally Diagnosed during Examination for Suspected Post-Human Papillomavirus Vaccination Syndrome

A 19-year-old Japanese woman was referred to us with the complaints of arthralgia and meralgia following human papillomavirus (HPV) vaccination. She received HPV vaccination at the age of 15 years and three years later, she developed intermittent arthralgia, meralgia, and numbness in limbs. There were no orthostatic dysregulation symptoms. She had hypertelorism, and brachydactyly in both the hands, and revealed mild cubitus varus deformity with lateral instability. X-ray examination disclosed hypoplasia of the humeral capitellum and trochlea in elbow joints. G-banded chromosomes were shown to be composed of 48, XXXX. She was, therefore, diagnosed with XXXX syndrome, which explained the reason for her limb symptoms. Although some girls with HPV vaccination complain of various symptoms including limb pain and numbness, exact underlying cause of these symptoms needs to be ascertained carefully for reaching a final diagnosis.

Update on human papillomavirus vaccination: Where are we now?

Infection with human papillomavirus(HPV) is the major cause of pre-invasive and invasive lesions of the urogenital tract, resulting in morbidity and mortality worldwide. HPV-related infection is responsible for most cases of cervical cancer, a leading cause of cancer death in women worldwide. Developed countries have screening programs in place to detect precancerous lesions at early stages; in resource-limited settings however, HPV related diseases are often identified in advanced stages. This is due to limitations in the availability and roll out of effective screening programs. The relatively recent availability of the HPV vaccine has provided a new public health opportunity to decrease the incidence of HPV-related disease. The high mortality rates seen in developing countries could be reduced through effective implementation of HPV vaccination programs. Large trials have proven the efficacy of bivalent, quadrivalent vaccine and most recently 9-valent vaccine. Uptake in vaccination remains low due to multiple barriers including lack of education, lack of access, and costs. New strategies are being assessed to increase access, increase knowledge and reduce costs that may result in feasible vaccination programs worldwide. The goal of this article is to review the effectiveness and safety of the current HPV vaccines available, vaccine delivery strategies, cost effectiveness, and efforts to improve the acceptability. A literature search was conducted through Pub Med using the terms "HPV vaccination, and safety, and males, and acceptability and strategies, and cost effectiveness,"focusing on articles published between 2006 and 2015. The most relevant and larger scale trials were evaluated for discussion.

Human Papillomavirus as an Independent Predictor in Oral Squamous Cell Cancer

Aim There is an increasing evidence for the role of high risk human papillomavirus （HPV） in the pathogenesis of oral squamous cell carcinoma （OSCC）. The purpose of this study is to evaluate the relevance of HPV infection to the survival and prognosis of OSCC. Methodology Fifty-two patients with OSCC were followed from 4 to 88 months with a median of 50.7 months. HPV DNA was identified in formalin-fixed, paraffin-embedded tumor specimens by nested PCR with MY09/MY11 and GP5^＋/GP6^＋ primer pairs and the HPV genotype was determined by direct DNA sequencing. Association between the HPV status and risk factors for cancer as well as tumor-host characteristics were analyzed.Survival curves were calculated by the Kaplan-Meier method and analyzed using the log-rank test. Results HPV was found in 40.4% of the tumors with HPV16 accounting for 63.5%, HPV18 for 30.8%, HPV6 for 3.9% and HPVll for 1.8%. No infection with more than one HPV genotype was detected. HPV infection was significantly associated with poor histological grade, TNM stage Ⅰ -Ⅱ, alcohol usage and no smoking status. Multivariate analysis showed that HPV had an independent prognostic effect on the overall survival after adjusting other confounding factors such as histological grade, TNM stage and tobacco usage. The presence of HPV was significantly correlated with a better survival in patients with OSCC. Conclusion HPV infection can act as an independent predictor for the survival and prognosis of OSCC.

Human Papilloma Virus Vaccine Acceptability and Its Associated Factors among Mothers of Female Children 9 - 14 Years in Ndola District of Zambia

Zambia has the second-highest incidence of HPV-related cervical cancer in sub-Saharan Africa, with a rate of 53.7 per 100,000 women, despite the availability of prophylactic HPV vaccines targeting HPV types 16 and 18. As parental consent is often required for adolescent vaccinations, understanding the factors influencing parental acceptance is essential. This study aimed to assess the acceptability of the human papillomavirus (HPV) vaccine and its associated factors among mothers of female children aged 9 - 14 years in Ndola, Zambia. This cross-sectional survey involved 350 mothers from selected townships in Ndola District and utilized multivariable logistic regression to analyze data. The findings revealed an HPV vaccine acceptability rate of 61.8%. Key factors influencing vaccine acceptance included knowledge of HPV, occupational status, and alcohol consumption. Mothers who had knowledge of HPV were 2.41 times more likely to accept vaccination for their daughters [AOR 2.41 (95% CI: 1.63 - 3.62)]. Employment status also played a significant role, with employed mothers being 1.47 times more likely to accept the vaccine [AOR 1.47 (95% CI: 1.02 - 2.13)]. Additionally, mothers who did not consume alcohol were 1.81 times more likely to accept the vaccine for their daughters [AOR 1.81 (95% CI: 1.22 - 2.66)]. We conclude that the HPV vaccine acceptability rate in Ndola, Zambia, remains suboptimal. This underscores the need for targeted interventions, such as public health campaigns and educational programs, to improve HPV vaccine knowledge and acceptance, particularly among specific demographic groups. Enhancing understanding of the HPV vaccine’s benefits could contribute to reducing the high burden of cervical cancer in Zambia.

CONSTRUCTION AND IMMUNOGENICITY OF HUMAN PAPILLOMAVIRUS TYPE 6B L1 RECOMBINANT PLASMID

To construct a DNA vaccine as a prophylactic model to prevent condyloma acuminatum and detect its immu-nogenicity in mice. Methods The major capsid protein (L1) gene of human papillomavirus (HPV) 6b was inserted into an eukaryotic ex-pression plasmid (pcDNA3.1). The recombinant plasmid was transfected into COS-7 cells. Western blot were performed to detect whether L1 protein can be expressed in eukaryotic cells. Eighteen female BALB/c mice were tested for immunoge-nicity study. Results The recombinant plasmid (pcDNA3.1-HPV6bL1) was verified as HPV6b L1 gene by sequencing. Western blot showed specific strip. Anti-L1 protein antibodies could be detected in the mice’s sera inoculated with pcDNA3.1-HPV6bL1. Similarly, IL-4, IL-2, and IFN-γ were increased in the same mice. Conclusion HPV6b L1 recombinant plasmid was constructed successfully which had immunogenicity for BALB/c mice. It provided experimental evidence for the research of DNA vaccine of condyloma acuminata..-

Apoptosis of HeLa cells inhibited by human papillomavirus type 16 E6 protein interacting with hDaxx

Objective: To study the interaction of human papillomavirus type 16 (HPV16 E6) protein and human death domain associated protein (hDaxx) and its effect on apoptosis of HeLa cells to provide the experimental basis for exploring the oncogenic mechanism of HPV16 E6 protein. Methods: Recombinant vector of pGADT7/E6 or pGBKT7/hDaxx was con- structed. The interaction of E6 protein and hDaxx was detected by yeast two-hybrid system. Their expression in yeast was detected by Western blotting. The eukaryotic plasmids of E6 and hDaxx were co-transfected into HeLa cells. Apoptosis was induced by 5-FU. The apoptotic rate was measured by flow cytometry (FCM). Results: E6 protein had intracellular interaction with hDaxx. The apoptotic rate was rising with the increase in the transfection quantity of pcDNA3.1 (-) / hDaxx in pcDNA3.1 (-) /E6 and pcDNA3.1 (-) / hDaxx co-transfected cells. The difference was significant ( P < 0. 01). Conclusion: There is intracellular interaction between HPV16 E6 protein and hDaxx. The over-expression of hDaxx can increase the sensitivity of E6 protein positive HeLa cells to 5-FU. The effect was in a dose dependent manner. HPV16 E6 protein inhibited the apoptosis of HeLa cells by interacting with hDaxx.

Detection and Identification of Human Papillomavirus in Cervical Adenocarcinoma

Objective： To evaluate the rate and types of human papillomavirus （HPV） infection in cervical adenocarcinoma. Methods： We detected and identified HPV in 67 lesions using PCR based reverse line blot hybridization and DNA sequencing. Among the 67 patients, 53 were diagnosed as cervical adenocarcinoma and 14 as cervical adenosquamous carcinoma. First a fragment of 150 bp was amplified from the L1 region of HPV with GP5/GP6 primers. If the result was negative, a short fragment of 65 bp was amplified from the L1 region with SPFI/SPF2 primers. Results： 6 cases were eliminated from the study because of unsatisfied DNA extraction. The total positive rate of HPV DNA detected by PCR in cervical adenocarcinoma and adenosquamous carcinoma was 91.8% （56/61）. Using general primer GP5/GP6, the positive rate was 50.8% （31/61）. Using SPF primers for the 30 negative cases, 25 additional HPV positive cases were founded. All the positive samples had at least one of the high risk types. HPV16 was the most preferential type followed by HPV18, 31, 39 and 45. The infection of HPV 16 and 18 accounted for about half of HPV-positive adenocarcinoma. Multiple HPV infections were found in 21.4% （12/56） of the cases. Conclusion： The high risk type of HPV is associated with cervical adenocarcinoma. Single infection is more frequently presented than multiple infections, no single type of HPV plays a predominated role even HPV16 and 18 are the major types.

CONSTRUCTION OF A RECOMBINANT ADENOVIRUS VECTOR OF HUMAN PAPILLOMAVIRUS TYPE 16 L1_E7C

Objective: Human papillomaviruses are closely associated with human cervical cancer, especially HPV types 16 and 18. At present, HPV can not be produced in large quantity; it also has tumorgenicity and these properties of HPV have seriously hampered the development of HPV vaccine. HPV type 16 LI proteins can assembled into virus-like particles (VLP), which are morphologically identical to the nature virion. In order to develop the recombinant adenovirus vectors of HPV, we constructed a recombinant adenovirus shuttle plasmid pCA14 L1-E7C. Methods: Human papillomavirus type 16 LI open reading frame without terminator codon (TAA) (5559–7152) and E7C (682–855) were amplified using PCR. The L1 and E7C fragments were inserted into pGEM-T easy vectors by T-A strategy, named pTAL1 and pTAE7C. pTAL1 was cut with Hind III and BgIII, the pTAE7C with BamHI and ClaI. The L1 DNA fragment, E7C and pBluesscript SK were ligated together using T4 DNA ligase. pBSL1-E7C and pBSL1-E7C was digested with Hind III and Xhol. The L1-E7C fragment was inserted into adenovirus shuttle plasmids pCA14, named pCA14L1-E7C. DNA sequence results indicated that The L1-E7C DNA fragment can encode the HPV16L1-E7 fusion protein correctly. Results: The L1 and E7C DNA fragments were amplified by PCR and recombinant plasmid pTAL1, pTAE7C, pBSL1-E7C and pCA14L1-E7C were constructed correctly. The pCA14L1-E7C can be used in the further research work, cotransfected the 293 cell with the parent adenovirus pBHG10. Conclusion: Our results indicated that we have constructed a HPV16L1-E7 fusion DNA fragments and the adenovirus shuttle plasmids pCAL1-E7C for the further research.

Expression of Human Papillomavirus in Mammary Carcinoma and its Possible Mechanism in Carcinogenesis

To explore the role of Human papillomavirus (HPV) in mammary carcinogenesis, the expression of the HPV-16, iNOS , P53 and hTERT proteins in breast carcinomas and their relationships were investigated. 52 samples of breast cancer and 16 samples of benign breast tumors were assayed using the immunohistochemical SP method for detection of protein expression levels. The expression of HPV-16, iNOS, P53 and hTERT proteins in a mammary carcinoma was 44.2%, 57.7%, 63.5% and 59.6% respectively, which was significantly greater than the corresponding levels in the benign group. The expression of iNOS, P53 and hTERT was correlated with the presence of an HPV-16 infection in a mammary carcinom(aP<0.05). The connection between these events might also involve the iNOS, mutated type P53 and the hTERT protein.

The Relationship between Human Papillomavirus and Oesophageal Squamous Cell Carcinoma in China—A Review of the Evidence

Background: China has one of the highest incidence rates of oesophageal cancer in the world. The role of human papillomavirus (HPV) has been extensively researched in oesophageal squamous cell carcinoma (OSCC) with indeterminate results. The majority of these studies have been conducted in the Chinese population. Evidence for a definitive HPV-OSCC association could potentially support prophylactic vaccination in target populations, highlighting the need for ongoing investigation. The aim of this review is to summarise the findings of HPV DNA in OSCC tissue in Chinese subjects, with a view to informing further research in this area. Methods: A systematic literature search of the Chinese National Knowledge Infrastructure (CNKI) database, Medline, Embase and PubMed was conducted for all studies in English and Chinese language, examining OSCC tissue for HPV DNA in China. Reference lists of retrieved articles were reviewed and hand searches of relevant, key journals were conducted, to source articles which were not electronically indexed. Sixty-four studies met our selection criteria. Data from case-control and cross-sectional studies were analysed separately for any HPV-OSCC association, using the Epi InfoTM 3.5.3 software program. Results: From all studies conducted in the Chinese population, 2166/5953 (36%) of all OSCC tissue and 478/1684 (28%) of healthy control tissue, tested positive for HPV. We found that 11/16 case-control and cross-sectional studies had a statistically significant crude odds ratio, which supported a potential HPV-OSCC association. The largest study, carried out in the high incidence County of Anyang in Henan Province, reported 207/265 (78%) OSCC tissues testing positive for HPV DNA against 203/357 (57%) controls and had an unadjusted odds ratio of 2.71 (p-value Conclusion: A rigorous meta-analysis would improve interpretation of the data and a well-designed large-scale case-control study is warranted. If a link is found between HPV and OSCC, prophylactic HPV vaccines could be of significant benefit in China.

THE DETECTION OF P53 GENE IN HUMAN CERVICAL CARCINOMA WITH AND WITHOUT HUMAN PAPILLOMAVIRUS INFECTION

The special primers Of p53 exon 7 as wed as HPV16 E6 and E7 ORFs (Opening Rending Frame) were used with PCR, PCR-SSCP technique, and 35 specimens of cervical carcinoma were examined. The results were as follows: ① HPV16 E6, E7 DNA was found in 25/35 specimens (71. 4%),which proved again HPV16 Infection an important event in cervical carcinogenesis. However only 11/35 (31.42% ) bad E6 and E7 ORFs simultaneously, 3/35 (8. 57%) and 11/35 (31. 42% ) had only E6 or E7 respectively. ② No mutation and LOH (Loss of Heterozygote) of p53 exon 7 were found in allof 35 specimens. Additionally in the present study, we developed a non-isotopic PCR-SSCP method.

Evaluation of Awareness of Human Papillomavirus and Cervical Cancer among Female Undergraduates of a Private Mission University in Southwestern Nigeria

Background: Human papillomavirus infection is most prevalent in the younger population and causes cervical cancer, which is the leading cause of cancer death worldwide. In 2018, cervical cancer was estimated to be 570,000 cases and 311,000 deaths;it ranked as the fourth most commonly diagnosed cancer and the fourth leading cause of cancer death in women. Cervical cancer can be prevented through health education and vaccination against HPV. This study aimed at evaluating the level of awareness of human papillomavirus and cervical cancer among female undergraduate students of Babcock University, Ogun state of Nigeria. Methodology: This was a cross-sectional, questionnaire-based study conducted among 310 female undergraduates of Babcock University in Nigeria from January to April 2019. The selection technique was a multistage random sampling method. The data collection was done using structured and self-administered questionnaires. Data collected were analyzed using IBM Statistical Package for Social Sciences (SPSS) statistics for windows version 25 and were presented in summary charts and frequency tables. P-values less than or equal to 0.05 were considered statistically significant. Results: Of 310 female students, 296 (95.5%) were aware of HPV infections. The majority, 215 (69.4%) of the students knew that HPV is sexually transmitted. There was poor knowledge of the risk factors of HPV infection. Only, 65 (21.0%) were aware that HPV infection causes cervical cancer. A few proportions of students 79 (25.4%) were aware of the HPV vaccine. Consequently, only 44 (14.2%) have received HPV vaccination and some complained about the cost as a significant reason for not being vaccinated against HPV infection. Conclusion: The level of awareness of HPV infection, cervical cancer, and HPV vaccine uptake was very low in this study. There is a need to improve health education and awareness campaigns among students about HPV infection, cervical cancer, and HPV vaccine uptake.
