MCur / Department of Advanced Nursing Science / Cervical cancer remains one of the major public health problems globally, despite the fact that it is preventable and curable if identified at an early stage. Currently, cervical cancer is the leading cause of death among women in Sub-Saharan Africa where the knowledge about the disease is scarce among the affected population. Methods A quantitative cross-sectional survey was conducted in Thulamela Municipality of Limpopo Province. The purpose of the study was to assess the knowledge of cervical cancer prevention among women in four villages in Thulamela Municipality. The population of the study was composed of all women aged above 30 in the villages Malamulele, Mhinga, Muledane and Phiphidi. A sample of one thousand five hundred and forty-six (1546) was drawn using random sampling. Quantitative data were collected using a twenty-six-item questionnaire. The data were coded and then processed using the Statistical Package for Social Sciences to produce frequency tables and descriptive statistics such as chi-square and correlation. Results A number of findings were made in this study. The majority of the women in this study had little or no knowledge about cervical cancer, human papilloma virus and vaccines. The majority of the women had little or no knowledge on cervical cancer risk factors and how the disease is spread. These findings were confirmed by chi-squared values at p<0.05 and showed significant association between variables: that young women were likely to be aware of cervical cancer compared to elderly women, educated women were more likely to be knowledgeable about cervical cancer than those with low education attainment, elderly women were more likely to be not worried about cervical cancer compared to young women. Correlation, Pearson rho scores at p<0.05 showed significant correlations knowledge of cervical cancer and age (negative), knowledge and education (positive). The findings signified the need for cervical cancer prevention education in Vhembe District, and the need for primary health care nurses to promote access to such services through robust health education. vi Recommendations The study made a number of practical recommendations likely to educate women about cervical cancer, human papilloma virus and its prevention. These include: The possibility of large hospitals having their own small broadcasting stations that will frequently disseminate information throughout the local municipalities, road shows and use of informal sector like politicians and traditional healers in disseminating information.

This qualitative study explored and described the experience of African women diagnosed with both HIV/AIDS and cervical cancer in order to gain an understanding of the experience of both illnesses as lived by these women. Phenomenological research methods were employed using in-depth semi-structured interviews. Communication as a strategy facilitating diagnosis, disclosure, acceptance and support for women with HIV/AIDS and cervical cancer emerged as the main theme, followed by the experience of physical symptoms and emotional experiences. The study shows the importance of communication in the management and support of these women attending public health institutions and in the community. For communication to occur the relationship between healthcare professionals and women diagnosed with HIV/AIDS and cervical cancer is very important. Treatment approaches in radiation therapy need to be developed for women diagnosed with HIV/AIDS and cervical. More research is needed in this area (HIV/AIDS and cervical cancer). / Health Studies / M.A. (Public Health)

MSc (Microbiology) / Department of Microbiology / BACKGROUND: Human papillomavirus (HPV) is a common sexually transmitted virus known to be a causative agent of cervical cancer (CC), one of the most frequent cancers in women worldwide. HPV is a double stranded DNA virus of approximately 7,900 bp; belonging to Papillomaviridae family. To date, about 202 low risk (LR) and high risk (HR) HPV genotypes have been identified. However, available vaccines against HPV infection are designed based on the most common known genotypes. Therefore, it is critical to understand the scope and diversity of HPV genotypes in all geographical locations which can help to inform the design and development of future vaccines. OBJECTIVE: The objective of this study was to describe the burden and diversity of HPV genotypes in a cohort of women in routine care in northern South Africa. METHODS: Eighty seven women consented to participate in the study and each provided a specimen for analysis. With the help of qualified health care practitioners, Aptima Cervical Specimen Collection and Transport Kit (Hologic, San Diego, CA) was used to collect cervical specimens from each study participant following the manufacturer’s procedure. Total DNA was purified from the cervical pellet using QIAamp DNA mini kit (Qiagen, Hilden, Germany) according to the manufacturer’s instructions. The purified DNA was then subjected to a single round conventional PCR in a reaction volume of 100 μl to amplify HPV L1 gene comprising of approximately 450 bp. A portion of each PCR amplicon from each participant was denatured, hybridized and genotyped using the Linear Array HPV genotyping Test Kit (Roche Molecular Systems, Inc. Branchburg, NJ USA). The kit is designed to detect 37 HPV genotypes (genotypes 6, 11, 16, 18, 26, 31, 33, 35, 39, 40, 42, 45, 51, 52, 53, 54, 55, 56, 58, 59, 61, 62, 64, 66, 67, 68, 69, 70, 71, 72, 73, 81, 82, 83, 84, IS39 and CP6108). To detect the HPV genotypes, the Linear Array (LA) reference guide was used for results interpretation following the manufacturer’s instructions. The other portion of each of the amplicons was subjected to next generation sequencing (NGS) using the Illumina MiniSeq platform. Using the Nextera XT DNA Library preparation kit, an initial input of 1ng genomic DNA was tagmented, cleaned up, normalized and pooled. The pooled library was then denatured with 0.1 N NaOH and diluted into a final volume of 500 μl at 1.8 pM then sequenced using the Local Run Manager option following the manufacturer’s instructions. The generated sequence data was downloaded into fastaQ format and analysed using Genious 11.0.5 software. RESULTS: Of the 87 participants, the overall proportion of women harbouring HPV DNA by linear array (LA) PCR was 23% (n=20). Of the 20, 16 (80%) were living with HIV. However, this difference was not significant (p=0.077). Genotyping data generated by Roche LA method was successful for all the 20 positive amplicons. In this study, 27 (73%) of the 37 HPV genotypes incorporated in the Roche Linear Array method were detected. The detected genotypes include: types 84, 83, 81, 73, 72, 71, 70, 69, 68, 66, 62, 61, 59, 54, 53, 52, 51, 45, 42, 39, 35, 26, 18, 16, 6, IS39 and CP6108. Most women (15/20;75%) harboured multiple infections compared to single infection. In terms of genotypes distribution, the most frequent genotypes detected LR HPV types in increasing order of frequency included HPV type 61 and 83 (12%), 62 (36%) and 81 (43%). On the other hand, HPV type 66, 53, 52, 51, 18 and 16 were the most common genotypes detected HR HPV types. In contrast, although genotyping data was successfully generated from 15 of 20 women (75%), NGS technology was seen to be more sensitive compared to Roche LA method. Nearly all the detected genotypes identified by the commercial kit were detected by NGS. In addition, NGS detected 10 namely: HPV types 11, 31, 33, 40, 55, 56, 58, 64, 67, and 82 that were not detected by the LA yet incorporated in the kit. Moreover, it was observed that NGS identified additional 6 HPV types including HPV types 2, 27, 30, 35, 85 and 102 not incorporated in the Roche LA kit. A similar distribution of HPV multiple infections was observed in the study population, however, high frequency of 93% (14 of 15) was detected by NGS. The proportion of women harbouring one or more of the 22 LR HPV types was 100% (n=15).The most frequent LR genotypes in increasing order of frequency was HPV type 62 and 70 (27%), 6 (40%) and 11 (47%). HPV types 40, 42, 54, 72, 64, and 81 were the least detected genotypes with n=1 (7%) each. Furthermore, the common combination observed among the participants was type 6 and 11. In contrast, the most frequent detected genotypes in the study population by NGS under the HR HPV types in increasing order of frequency include type 35 (21%), 39, 56 and 82 (29%), 68 (36%) and 51 (50%). In addition, HPV types 26, 31, 45, 53, 56, 58 and 66 were the least detected genotypes n=1 (7%) in the study population. HPV 39 and 68 were observed as the common combination detected under HR HPV types. Following genotyping by LA and NGS, the demographic and clinical data of all the 20 positive subjects by PCR were subjected to statistical analysis to determine the association between HPV positive DNA status and associated risk factors. Smoking status (p=0.000), age at first sexual intercourse (p=0.011), vaccination status (p=0.000), gender of sexual partner (p=0.000), highest level of education (p=0.004), marital status (p=0.008) and number of sexual partners (p=0.000) were found to be having a positive statistical association. CONCLUSION: Amplification of targeted HPV DNA from cervical specimens demonstrated the presence of HPV infection in the study cohort, with a proportion of 23%. The findings illustrate that there is a diversity of HPV genotypes prevalent in the study population as shown by Roche LA and NGS methods. However, the NGS method was observed to be more sensitive than Roche LA in detecting HPV genotypes. Furthermore, NGS identified 6 additional HPV types not incorporated in the Roche LA. Thus, there are genotypes that may be present in the study population that the Roche commercial kit may fail to detect. Therefore, is it imperative to use both genotyping methods to confirm HPV genotypes. / NRF
