    (International Journal of Gynecology and Obstetrics, 2013) Ogilvie, Gina S.; Mitchell, Sheona; Sekikubo, Musa; Biryabarema, Christine; Jeronimo, Jose; Miller, Dianne; Steinberg, Malcolm; Money, Deborah M.
    Objective: To examine the feasibility of a community-based screening program using human papillomavirus (HPV) self-sampling in a low-income country with a high burden of cervical cancer. Methods: A pilot study was conducted among 205 women aged 30–69 years in the Kisenyi district of Kampala, Uganda, from September 5 to October 30, 2011. Women were invited to provide a self-collected specimen for high-risk oncogenic HPV testing by outreach workers at their homes and places of gathering in their community. Specimens were tested for HPV, Neisseria gonorrhoeae and Chlamydia trachomatis. Women who tested posi tive for HPV were referred for colposcopy, biopsy, and treatment at a regional hospital. Results: Of the 199 women who provided a specimen, 35 (17.6%) tested positive for HPV. The outreach workers were able to provide results to 30 women (85.7%). In all, 26 (74.3%) of the women infected with HPV attended their colposcopy appointments and 4 (11.4%) women were diagnosed with grade 3 cervical intraepithelial neoplasia. Conclusion: Self-collection of samples for community-based HPV testing was an acceptable option; most women who tested positive attended for definitive treatment. Self-sampling could potentially allow for effective recruitment to screening programs in limited-resource settings. © 2013 International Federation of Gynecology and Obstetrics.

    A Risk Prediction Model for the Assessment and Triage of Women with Hypertensive Disorders of Pregnancy in Low-Resourced Settings: The miniPIERS (Pre-eclampsia Integrated Estimate of RiSk) Multi-country Prospective Cohort Study
    (PLOS Medicine, 2014-01) Payne, Beth A.; Hutcheon, Jennifer A.; Ansermino, J. Mark; Hall, David R.; Bhutta, Zulfiqar A.; Bhutta, Shereen Z.; Biryabarema, Christine; Grobman, William A.; Groen, Henk; Haniff{, Farizah; Li, Jing; Magee, Laura A.; Merialdi, Mario; Nakimuli, Annettee; Qu, Ziguang; Sikandar, Rozina; Sass, Nelson; Sawchuck, Diane; Steyn, D. Wilhelm; Widmer, Mariana; Zhou, Jian; Dadelszen, Peter von
    Background: Pre-eclampsia/eclampsia are leading causes of maternal mortality and morbidity, particularly in low- and middle- income countries (LMICs). We developed the miniPIERS risk prediction model to provide a simple, evidence-based tool to identify pregnant women in LMICs at increased risk of death or major hypertensive-related complications. Methods and Findings: From 1 July 2008 to 31 March 2012, in five LMICs, data were collected prospectively on 2,081 women with any hypertensive disorder of pregnancy admitted to a participating centre. Candidate predictors collected within 24 hours of admission were entered into a step-wise backward elimination logistic regression model to predict a composite adverse maternal outcome within 48 hours of admission. Model internal validation was accomplished by bootstrapping and external validation was completed using data from 1,300 women in the Pre-eclampsia Integrated Estimate of RiSk (fullPIERS) dataset. Predictive performance was assessed for calibration, discrimination, and stratification capacity. The final miniPIERS model included: parity (nulliparous versus multiparous); gestational age on admission; headache/visual disturbances; chest pain/dyspnoea; vaginal bleeding with abdominal pain; systolic blood pressure; and dipstick proteinuria. The miniPIERS model was well-calibrated and had an area under the receiver operating characteristic curve (AUC ROC) of 0.768 (95% CI 0.735–0.801) with an average optimism of 0.037. External validation AUC ROC was 0.713 (95% CI 0.658–0.768). A predicted probability $25% to define a positive test classified women with 85.5% accuracy. Limitations of this study include the composite outcome and the broad inclusion criteria of any hypertensive disorder of pregnancy. This broad approach was used to optimize model generalizability. Conclusions: The miniPIERS model shows reasonable ability to identify women at increased risk of adverse maternal outcomes associated with the hypertensive disorders of pregnancy. It could be used in LMICs to identify women who would benefit most from interventions such as magnesium sulphate, antihypertensives, or transportation to a higher level of care.

    Understanding the role of embarrassment in gynaecological screening: a qualitative study from the ASPIRE cervical cancer screening project in Uganda
    (BMJ Open, 2014) Teng, Flora F; Mitchell, Sheona M; Sekikubo, Musa; Biryabarema, Christine; Byamugisha, Josaphat K; Steinberg, Malcolm; Money, Deborah M; Ogilvie, Gina S
    Objective: To define embarrassment and develop an understanding of the role of embarrassment in relation to cervical cancer screening and self-collected human papillomavirus (HPV) DNA testing in Uganda. Design: Cross-sectional, qualitative study using semi structured one-to-one interviews and focus groups. Participants: 6 key-informant health workers and 16 local women, purposively sampled. Key informant inclusion criteria: Ugandan members of the project team. Focus group inclusion criteria: woman age 30–69 years, Luganda or Swahili speaking, living or working in the target Ugandan community. Exclusion criteria: unwillingness to sign informed consent. Setting: Primary and tertiary low-resource setting in Kampala, Uganda. Results: In Luganda, embarrassment relating to cervical cancer is described in two forms. ‘Community embarrassment’ describes discomfort based on how a person may be perceived by others. ‘Personal embarrassment’ relates to shyness or discomfort with her own genitalia. Community embarrassment was described in themes relating to place of study recruitment, amount of privacy in dwellings, personal relationship with health workers, handling of the vaginal swab and misunderstanding of HPV self collection as HIV testing. Themes of personal embarrassment related to lack of knowledge, age and novelty of the self-collection swab. Overall, embarrassment was a barrier to screening at the outset and diminished over time through education and knowledge. Fatalism regarding cervical cancer diagnosis, worry about results and stigma associated with a cervical cancer diagnosis were other psychosocial barriers described. Overcoming psychosocial barriers to screening can include peer-to peer education, drama and media campaigns. Conclusions: Embarrassment and other psychosocial barriers may play a large role at the onset of a screening programme, but over time as education and knowledge increase, and the social norms around screening evolve, its role diminishes. The role of peer to-peer education and community authorities on healthcare cannot be overlooked and can have a major impact in overcoming psychosocial and social barriers to screening.

    Uptake of community-based, self-collected HPV testing vs visual inspection with acetic acid for cervical cancer screening in Kampala, Uganda: preliminary results of a randomised controlled trial
    (Tropical Medicine and International Health, 2015) Moses, Erin; Pedersen, Heather N.; Mitchel, Sheona M.; Sekikubo, Musa; Mwesigwa, David; Singer, Joel; Biryabarema, Christine; Byamugisha, Josaphat K; Money, Deborah M.; Ogilvie, Gina S.
    objectives To compare two cervical cancer screening methods: community-based self-collection of high-risk human papillomavirus (HR-HPV) testing and visual inspection with acetic acid (VIA). methods Pilot randomised controlled trial of 500 women aged 30–65 in the community of Kisenyi, Uganda. Women randomised to self-collection-based HR-HPV testing provided a cervico-vaginal swab for HR-HPV, and results were provided by phone after laboratory testing. Women who tested HPV positive were referred for VIA at the local health unit. Women randomised to VIA underwent screening at the local health unit, where women who tested positive with VIA were provided cryotherapy at time of screening, as per local standard of care. Women were referred for colposcopy when indicated. Outcome measures were uptake of screening, HR-HPV prevalence, VIA result and treatment rates. results In the HR-HPV arm, 248 of 250 (p < 0.01) women provided samples, while in the VIA arm, 121 of 250 (48.4%) women attended screening. Among the 73 of 248 HR-HPV-positive women, 45.2% (N = 33) attended VIA screening for follow-up, 21.2% (N = 7) of whom screened positive; five received treatment and two were missing clinical follow-up records. Of the 121 women in the VIA arm who attended screening, 13.2% (N = 16) screened positive; seven received cryotherapy, three refused treatment, five were referred to colposcopy; and one woman had suspected cervical cancer and received treatment after confirmatory testing. conclusions This pilot study demonstrated trial feasibility and willingness of the women to participate and be randomised successfully into the two arms. Self-collection-based cervical cancer screening had a higher uptake than VIA.

    War related sexual violence and it’s medical and psychological consequences as seen in Kitgum, Northern Uganda: A cross-sectional study
    (BMC International Health and Human Rights 2, 2010) Kinyanda, Eugene; Musisi, Seggane; Biryabarema, Christine; Ezati, Isaac; Oboke, Henry; Ochieng, Ruth Ojiambo-; Oguttu, Juliet Were; Levin, Jonathan; Grosskurth, Heiner; Walugembe, James
    Background: Despite the recent adoption of the UN resolution 1820 (2008) which calls for the cessation of war related sexual violence against civilians in conflict zones, Africa continues to see some of the worst cases of war related sexual violence including the mass sexual abuse of entire rural communities particularly in the Great Lakes region. In addition to calling for a complete halt to this abuse, there is a need for the systematic study of the reproductive, surgical and psychological effects of war related sexual violence in the African socio-cultural setting. This paper examines the specific long term health consequences of war related sexual violence among rural women living in two internally displaced person’s camps in Kitgum district in war affected Northern Uganda who accessed the services of an Isis-Women’s International Cross Cultural Exchange (Isis-WICCE) medical intervention. Methods: The study employed a purposive cross-sectional study design where 813 respondents were subjected to a structured interview as part of a screening procedure for an emergency medical intervention to identify respondents who required psychological, gynaecological and surgical treatment. Results: Over a quarter (28.6%) of the women (n = 573) reported having suffered at least one form of war related sexual violence. About three quarters of the respondents had ‘at least one gynaecological complaint’ (72.4%) and ‘at least one surgical complaint’ (75.6%), while 69.4% had significant psychological distress scores (scores greater than or equal to 6 on the WHO SRQ-20). The factors that were significantly associated with war related sexual violence were the age group of less than or equal to 44 years, being Catholic, having suffered other war related physical trauma, and having ‘at least one gynaecological complaint’. The specific gynaecological complaints significantly associated with war related sexual violence were infertility, chronic lower abdominal pain, abnormal vaginal bleeding, and sexual dysfunction. In a multivariable analysis the age group of less than or equal to 44 years, being Catholic and having ‘at least one gynaecological complaint’ remained significantly associated with war related sexual violence. Conclusion: The results from this study demonstrate that war related sexual violence is independently associated with the later development of specific gynaecological complaints.
