RESUMO

INTRODUCTION: Human papillomavirus (HPV) testing is transforming cervical screening globally. The World Health Organization (WHO) now recommends same-day HPV screen-and-treat for primary cervical screening in low- and middle-income countries (LMIC) but there is a lack of evidence on women's lived experience of testing positive for oncogenic HPV and receiving same-day treatment. This study aimed to address this knowledge gap among women participating in a same-day HPV screen-and-treat (HPV S&T) program in Papua New Guinea. METHODS: As part of a larger qualitative study, this paper explores the lived experiences of 26 women who tested positive for oncogenic HPV and were treated the same day. We analysed the data using the interpretative phenomenological analysis method. All data were managed using Nvivo 12.5. RESULTS: The interpretative phenomenological analysis led to three superordinate themes: 1) facing and alleviating initial worries, (2) transforming the disclosure process, and (3) connecting to their faith. Women's experiences of the same day HPV screen-and-treat were framed by initial emotional reactions to their positive HPV test result, and having access to treatment on the same day, which helped address their worries and fears, and transformed their experience of disclosing their test result and subsequent treatment to family and friends. CONCLUSION: This study shows that, while women experience similar initial emotional reactions, undergoing same day treatment quickly resolved the women's worries, making this program highly acceptable. Overall, women's engagement in the program confirmed its high acceptability and cultural congruence, leaving women feeling empowered and hopeful about their future, and the future of all Papua New Guinea women.

RESUMO

BACKGROUND: A field trial to evaluate a self-collect point-of-care HPV screen-and-treat (HPV S&T) program was implemented in two Well Women Clinics in Papua New Guinea (Papua New Guinea). Assessing the acceptability of a health intervention is a core element of evaluation. In this study, we examined women's acceptability of both self-collection and HPV S&T intervention in Papua New Guinea.  METHODS: Sixty-two semi-structured interviews were conducted with women who had undergone cervical screening in the same-day self-collected HPV screen-and-treat program in Madang and Western Highlands Provinces, Papua New Guinea. Data were thematically analysed using the Theoretical Framework of Acceptability (TFA) and managed using NVivo 12.5. RESULTS: Most women agreed that self-collection was transformative: it helped circumvent the culturally embarrassing pelvic examination and increased their self-efficacy, especially due to the provision of health education, instructions, and pictorial aids. The availability of same-day results, and treatment if indicated, was particularly valued by the women because it reduced the financial and temporal burden to return to the clinic for results. It also meant they did not need to wait anxiously for long periods of time for their results. Women also appreciated the support from, and expertise of, health care workers throughout the process and spoke of trust in the HPV-DNA testing technology. Most women were willing to pay for the service to ensure its sustainability and timely scale-up throughout Papua New Guinea to support access for women in harder to reach areas. CONCLUSION: This study reported very high levels of acceptability from a field trial of self-collection and HPV same-day screen-and-treat. The program was deemed culturally congruent and time efficient. This innovative cervical screening modality could be the 'solution' needed to see wider and more immediate impact and improved outcomes for women in Papua New Guinea and other high-burden, low-resource settings.

RESUMO

BACKGROUND: Testing and treatment during pregnancy is a well-established and cost-effective prevention strategy, which relies largely on use of rapid diagnostic tests (RDTs). Yet, in many low-income and-middle-income countries, the uptake of RDTs is suboptimal. A qualitative meta-synthesis was conducted to identify the barriers and enablers to use of HIV and syphilis RDTs among pregnant women in low-income and middle-income countries. METHODS: This review was conducted using PRISMA guidelines. Eligible studies included peer-reviewed publications, which used qualitative methods to explore HIV and syphilis RDT in antenatal care clinics in low-income and middle-income countries. Studies focusing on perspectives of pregnant women, healthcare workers and/or stakeholders were included. We used an inductive approach informed by a modified socioecological model to synthesise the data. RESULTS: 62 manuscripts met the eligibility criteria. For pregnant women, initial acceptance of the RDT and continuation in antenatal care depends on the perception that engaging in testing will be a beneficial experience for their baby and themselves, often influenced by the provision of services that are gender-sensitive, confidential, respectful, flexible and considers their well-being into the future. Local sociocultural beliefs about pregnancy and diseases, awareness of diseases and gender roles in society also influenced RDT acceptability among pregnant women. For healthcare workers, the ability to provide high-quality RDT care required ongoing training, accurate and easy to use tests, support from supervisors and communities, sufficient resources and staffing to provide services, and reliable salary. At the stakeholder level, well-developed guidelines and health system infrastructures were imperative to the delivery of RDT in antenatal clinics. CONCLUSION: Our findings highlight clear gaps to the provision of sustainable and culturally acceptable maternal HIV and/or syphilis screening using RDTs. In addition, greater attention needs to be paid to community stakeholders in promoting the uptake of RDT in antenatal clinics. PROSPERO REGISTRATION NUMBER: CRD42018112190.

RESUMO

BACKGROUND: Cervical cancer is the fourth most common cancer affecting women worldwide, with 85% of the burden estimated to occur among women in low and middle-income countries (LMICs). Recent developments in cervical cancer screening include a novel self-collection method for the detection of oncogenic HPV strains in the collected samples. The purpose of this review is to synthesise qualitative research on self-collection for HPV-based testing for cervical screening and identify strategies to increase acceptability and feasibility in different settings, to alleviate the burden of disease. METHODS: This review includes qualitative studies published between 1986 and 2020. A total of 10 databases were searched between August 2018 and May 2020 to identify qualitative studies focusing on the perspectives and experiences of self-collection for HPV-based cervical screening from the point of view of women, health care workers and other key stakeholders (i.e., policymakers). Two authors independently assessed studies for inclusion, quality, and framework thematic synthesis findings. The Socio-Ecological Model (SEM) was used to synthesize the primary studies. RESULTS: A total of 1889 publications were identified, of which 31 qualitative studies were included. Using an adapted version of SEM, 10 sub-themes were identified and classified under each of the adapted model's constructs: (a) intrapersonal, (b) interpersonal, and (c) health systems/public policy. Some of the themes included under the intrapersonal (or individual) construct include the importance of self-efficacy, and values attributed to self-collection. Under the intrapersonal construct, the findings centre around the use of self-collection and its impact on social relationships. The last construct of health systems focuses on needs to ensure access to self-collection, the need for culturally sensitive programs to improve health literacy, and continuum of care. CONCLUSION: This review presents the global qualitative evidence on self-collection for HPV-based testing and details potential strategies to address socio-cultural and structural barriers and facilitators to the use of self-collection. If addressed during the design of an HPV-based cervical cancer screening testing intervention program, these strategies could significantly increase the acceptability and feasibility of the intervention and lead to more effective and sustainable access to cervical screening services for women worldwide.

RESUMO

BACKGROUND: Cervical cancer is the fourth most common cancer affecting women worldwide. In the 1980s, it was found that the sexually transmitted disease human papillomavirus causes over 90% of all cervical cancer cases. Since that discovery, diagnostic technologies have been developed for the detection of human papillomavirus DNA in cervical samples. However, significant sociocultural and structural barriers remain. Considerable strides have taken place in recent years to address these barriers, such as the self-collection for human papillomavirus-based cervical screening method. OBJECTIVE: The purpose of this review is to synthesize qualitative evidence around the self-collection method and identify strategies to increase acceptability and feasibility in different settings. This qualitative synthesis will be used to better understand how to conceptualize and implement more effective, accessible, and socially and culturally acceptable cervical screening programs and policies globally. METHODS: A systematic search will be conducted in Global Health, Cochrane, CINAHL (Cumulative Index to Nursing and Allied Health Literature), ProQuest, ScienceDirect, EMBASE, EMCARE, Medline (OVID), Scopus, and Web of Science. Published and peer-reviewed articles will be included. Two reviewers will independently screen and assess the studies. The data will be coded and analyzed using a thematic synthesis process. The socioecological model will be used to organize emergent themes at the micro and macro levels. The results will be presented in narrative and tabular form. RESULTS: The article search and data extraction were completed in May 2020. The data were analyzed in June 2020. The review will be submitted for publication in Fall 2020. CONCLUSIONS: This review will present the global evidence of the perspectives and experiences of various key stakeholders and how these perspectives and experiences impact their decision-making process to perform or accept self-collection for human papillomavirus-based cervical screening. The review will provide guidance to implementation researchers as well as implications for future research.

RESUMO

Inherited retinal degenerations are blinding diseases characterized by the loss of photoreceptors. Their extreme genetic heterogeneity complicates treatment by gene therapy. This has motivated broader strategies for transplantation of healthy retinal pigmented epithelium to protect photoreceptors independently of the gene causing the disease. The limited clinical benefit for visual function reported up to now is mainly due to dedifferentiation of the transplanted cells that undergo an epithelial-mesenchymal transition. We have studied this mechanism in vitro and revealed the role of the homeogene OTX2 in preventing dedifferentiation through the regulation of target genes. We have overexpressed OTX2 in retinal pigmented epithelial cells before their transplantation in the eye of a model of retinitis pigmentosa carrying a mutation in Mertk, a gene specifically expressed by retinal pigmented epithelial cells. OTX2 increases significantly the protection of photoreceptors as seen by histological and functional analyses. We observed that the beneficial effect of OTX2 is non-cell autonomous, and it is at least partly mediated by unidentified trophic factors. Transplantation of OTX2-genetically modified cells may be medically effective for other retinal diseases involving the retinal pigmented epithelium as age-related macular degeneration.
