Cervical cancer screening outcomes in public health facilities in three states in Nigeria.

BACKGROUND: Cervical cancer continues to generate a significant burden of disease and death in low- and middle-income countries (LMICs). Lack of awareness and poor access to early screening and pre-cancer treatment contribute to the high mortality. We describe here cervical cancer screening outcomes in public health facilities in three states in Nigeria. METHODS: We conducted an observational study in 177 government health facilities in Lagos, Kaduna, and Rivers State, Nigeria from January to December 2021, in which we reviewed programmatic data collected through the newly introduced Cervical Cancer Prevention Program. Women who received screening and provided consent were enrolled into the study. Data were extracted from registers in the health facilities using SurveyCTO and descriptive statistical analysis was conducted using StataSE 15 (StataCorp, College Station, TX, USA). RESULTS: Eighty-three thousand, five hundred ninety-three women were included in the analysis including 6,043 (7%) WLHIV. 67,371 (81%) received VIA as their primary screening while 16,173 (19%) received HPV DNA testing, with 49 (< 1%) receiving both at the same time. VIA positivity was 7% for WLHIV and 3% for general population, while HPV prevalence was 16% for WLHIV and 8% for general population. Following a positive HPV result, 21% of women referred, completed triage examination. 96% of women identified with precancerous lesions, received treatment. 44% of women with suspected cancer were successfully referred to an oncology center for advanced treatment. Following treatment with thermal ablation, seven adverse events were reported. CONCLUSIONS: The Program has successfully increased women's access to screening and treatment of precancerous lesions. Almost all women who were eligible for pre-cancerous lesion treatment received it, often on the same day when screened using VIA. However, for women referred for a triage exam or due to suspected cancer, many did not complete their referral visits. More effort is required to ensure HPV positive women and women with suspected cancer are adequately linked to care to further reduce morbidity and mortality associated with cervical cancer in Nigeria. Implementation studies should be conducted to provide insights to improve the utilization of the existing centralized and point of care (POC) platforms to facilitate same day results, and to improve triage and treatment rates.

Human papillomavirus testing using existing nucleic acid testing platforms to screen women for cervical cancer: implementation studies from five sub-Saharan African countries.

OBJECTIVES: To demonstrate acceptability and operational feasibility of introducing human papillomavirus (HPV) testing as a principal cervical cancer screening method in public health programmes in sub-Saharan Africa. SETTING: 45 primary and secondary health clinics in Malawi, Nigeria, Senegal, Uganda and Zimbabwe. PARTICIPANTS: 15 766 women aged 25-54 years presenting at outpatient departments (Senegal only, general population) or at antiretroviral therapy clinics (all other countries, HIV-positive women only). Eligibility criteria followed national guidelines for cervical cancer screening. INTERVENTIONS: HPV testing was offered to eligible women as a primary screening for cervical cancer, and HPV-positive women were referred for visual inspection with acetic acid (VIA), and if lesions identified, received treatment or referral. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcomes were the proportion of HPV-positive women who received results and linked to VIA and the proportion of HPV-positive and VIA-positive women who received treatment. RESULTS: A total of 15 766 women were screened and tested for HPV, among whom 14 564 (92%) had valid results and 4710/14 564 (32%) were HPV positive. 13 837 (95%) of valid results were returned to the clinic and 3376 (72%) of HPV-positive women received results. Of women receiving VIA (n=2735), 715 (26%) were VIA-positive and 622 (87%) received treatment, 75% on the same day as VIA. CONCLUSIONS: HPV testing was found to be feasible across the five study countries in a public health setting, although attrition was seen at several key points in the cascade of care, namely results return to women and linkage to VIA. Once women received VIA, if eligible, the availability of on-site cryotherapy and thermal ablation allowed for same-day treatment. With sufficient resources and supportive infrastructure to ensure linkage to treatment, use of HPV testing for cervical cancer screening as recommended by WHO is a promising model in low-income and middle-income countries.

Implementing Patient-Directed Cancer Education Materials Across Nigeria.

PURPOSE: As access to cancer care expands in low-income countries, developing tools to educate patients is paramount. We took a picture booklet, which was initially developed by the nonprofit Global Oncology for Malawi and Rwanda, and adapted it for use in Nigeria. The primary goal was to assess acceptability and provide education. The secondary goals were (1) to describe the collaboration, (2) to assess knowledge gained from the intervention, (3) to assess patient understanding of their therapy intent, and (4) to explore patient's experiences via qualitative analysis. METHODS: We piloted the original English booklet at a single site and requested feedback from patients and providers. The booklet was updated; translated into Hausa, Yoruba, Igbo, and Pidgin English; and used at three additional sites. For the three-site cohort, we collected basic demographics, pretest and post-test assessing content in the booklet, and performed a qualitative analysis. RESULTS: The original booklet was widely acceptable and recommended by patients at site one (n = 31) and by providers (N = 26) representing all four sites. In the three-site cohort (n = 103), 94% of patients recommended the booklet. An immediate post-test focusing on when patients should present to care showed a statistically significant improvement in one of the seven questions. Fifty-one percent of the patients (n = 103) knew their treatment intent (curative v palliative). Qualitative analysis highlighted that the patient's thoughts on cancer are dominated by negative associations, although curability and modern therapy are also frequently cited. CONCLUSION: We adapted an educational booklet to a novel context and had it delivered by local partners. The booklet was widely recommended to future patients. The booklet had an impact on patient's knowledge of cancer treatment, potentially allowing for decreased abandonment.

Seasonal malaria chemoprevention packaged with malnutrition prevention in northern Nigeria: A pragmatic trial (SMAMP study) with nested case-control.

Integrating seasonal malaria chemoprevention (SMC), recommended by the WHO since 2012 to prevent malaria infection, with nutrition interventions may improve health outcomes and operational efficiencies. This study assessed the effects of co-packaging interventions on distribution coverage, nutrition, and clinical malaria outcomes in northern Nigeria. From August to November 2014, community volunteers delivered sulfadoxine-pyrimethamine and amodiaquine (SP-AQ) door-to-door each month to approximately 7,000 children aged 6-24 months in seven wards of Madobi, Kano State, Nigeria. In three of the wards children additionally received a lipid-based nutrient supplement (LNS-medium quantity), Plumpy Doz. Coverage, adherence, and anthropometric outcomes were assessed through baseline, midline, and endline household surveys. A facility-based case-control study was also conducted to estimate impact on clinical malaria outcomes. Coverage of SP-AQ was similar between arms at 89% (n = 2,409 child-months [88-90%]) in the SP-AQ only arm and 90% (n = 1,947 child-months [88-92%]) in the SP-AQ plus LNS arm (p = 0.52). Coverage of LNS was 83% (n = 2,409 child-months [81-84%]). Whilst there were marked changes in anthropometric status between baseline, midline and endline, these were largely accounted for by socioeconomic status and must be interpreted with care due to possible measurement issues, especially length-based indices. Overall nutritional status of our most robust measure, weight-for-age, does appear to have improved by endline, but was similar in the two study arms, suggesting no additional benefit of the LNS. While the odds of clinical malaria among those who received the intended intervention were lower in each study arm compared to children who did not receive interventions (SP-AQ only OR = 0.23 [0.09-0.6]; SP-AQ plus LNS OR = 0.22 [0.09-0.55]), LNS was not shown to have an additional impact. Coverage of SMC was high regardless of integrating LNS delivery into the SMC campaign. Supplementation with LNS did not appear to impact nutritional outcomes, but appeared to enhance the impact of SP-AQ on clinical odds of malaria. These results indicate that combining nutritional interventions with seasonal malaria chemoprevention in high-risk areas can be done successfully, warranting further exploration with other products or dosing. Trial Registration: ISRCTN 11413895.

Human-initiated disaster, social disorganization and post-traumatic stress disorder above Nigeria's oil basins.

Survivors of human-initiated disaster are at high risk for mental disorder, most notably post-traumatic stress disorder (PTSD). Studies of PTSD have tended to focus on soldiers returning home after combat or on refugees living in resettlement countries under conditions of relative safety. However, most survivors of human-initiated disasters continue to live in or near the places where they initially experienced trauma. Insufficient attention has been paid to social disorganization in situations of continuing unrest and to its role in creating or stabilizing the symptoms of PTSD. The current study took place in the Niger Delta region of Nigeria, the scene of long-standing violence and human rights abuse that reached its apogee in 1995. The investigation, which took place in 2002, focused on two villages, one that was heavily exposed to the conflict (A, the affected village), the other relatively spared (NA, not affected). Probability samples of 45 adult residents from A and 55 from NA were interviewed with a schedule that contained the PTSD module from the WHO Diagnostic Interview Schedule. The schedule also contained a measure of exposure to the violence and abuses during the height of the conflict, as well as measures of structural and social capital that are components of community resilience. These included economic security, a sense of moral order, a sense of safety and perceived social support. The six month period prevalence of PTSD was 60 percent in A, and 14.5 percent in NA. Degree of exposure to stress as well as compromised sense of moral order, not feeling safe, and perceived lack of social support were independent predictors of PTSD. In places like the Niger Delta, where people do not physically escape from past trauma, sociocultural disintegration may interfere with communal functioning, thereby eroding community capacity to promote self-healing.
