The Need for Societal Investment to Improve Cervical Cancer Outcomes in Nigeria: A commentary

Although cervical cancer is a preventable cancer with a well-known natural history, it remains a huge burden in developing countries of sub-Saharan Africa where organized cervical cancer screening services are lacking. Developed countries that have invested on providing organized screening programs have made substantial progress in reducing both incidence and mortality due to cervical cancer. Implementing evidence-based interventions such as human papillomavirus (HPV) vaccination of young girls, early detection and treatment of premalignant conditions of the cervix through conventional Pap cytology, HPV screening or visual aided inspection with acetic acid could significantly reduce incidence of new cases at population level. Societal investment for such preventive services and provision of effective treatment for those diagnosed at early stages will yield economic benefits in reducing premature deaths of women at the prime of their productive lives. From a societal perspective, this should be a priority area for national investment towards the achievement of sustainable development in Nigeria and similar settings in Africa. Keywords: Cancer prevention, treatment, society, cervical cance

Incidence and risk factors for pre-eclampsia in Jos Nigeria

Objective: We sought to estimate the incidence and risk factors associated with development of pre-eclampsia (PET) in Jos, Nigeria.Methods: An open cohort study of singleton pregnant women attending the antenatal clinic of Jos University Teaching Hospital (JUTH), Nigeria between November 2010 and August 2011. Eligible healthy women at ≤ 20 weeks gestation were enrolled and followed up until delivery or development of pre-eclampsia. Baseline demographic characteristics including weight, height and body mass index (BMI) were collected at enrollment. Incidence, risk factors and hazard ratios for developing PET were estimated with corresponding 95% confidence intervals and p-values. All statistical analyses were done with STATA version 11, college station, Texas, USA.Results: A total of 2416 pregnant women were screened for eligibility out of which 323 were eligible for inclusion. The incidence of PET was 87.9 per 1,000 pregnancies (8.8%). The significant risk factors for PET were previous history of PET (RR=5.1, 95% CI: 2.2-12.1) and BMI at booking ≥ 25 kg/m2 (RR=3.9, 95% CI: 1.5-10.0).Conclusion: The incidence of PET was relatively high in our cohort in Jos, Nigeria and a previous history of the disease and overweight or obese pregnant women have a significant hazard of developing the disease in the course of gestational follow up. Targeting women with these characteristics for early preventive intervention and close surveillance at the antenatal booking clinic may help in prevention of the disease and its complications.Keywords: Pre-eclampsia, incidence, risk, hazard, Jos Nigeria

Evaluation of Fecundity for Variants of Laboratory Bred Glossina Morsitan Submorsitan and Glossina Palpalis Palpalis Exposed to Ethanol at Larval Stage

22 nos Larvae of Glossina morsitan submorsitan and Glossina palpalis palpalis collected from the insectary after larviposition was immediately exposed to 50% ethanol and observed for puparium time; Glossina Palpalis palpalis indicated an average of 13.22min while Glossina morsitan submorsitan indicated an average of 10.72mins. The average emergence period of the F1 generation of young tsetse flies for both species were 30 days. After mating, 16 nos exposed variant of all Glossina morsitan submorsitan did not produce any offspring while 2 nos of Glossina palpalis palpalis larviposited. The study reveals that Glossina palpalis palpalis maintained a normal fecundity irrespective of larvae exposure to alcohol while Glossina morsitan submorsitan maintained a null fecundity thus showing remarkable result for possible derivative insecticidal control of the Glossina morsitan submorsitan.

Challenges and priorities for pediatric critical care clinician-researchers in low- and middle-income countries

IntroductionThere is need for more data on critical care outcomes and interventions from low- and middle-income countries (LMIC). Global research collaborations could help improve health-care delivery for critically ill children in LMIC where child mortality rates remain high.Materials and methodsTo inform the role of collaborative research in health-care delivery for critically ill children in LMIC, an anonymous online survey of pediatric critical care (PCC) physicians from LMIC was conducted to assess priorities, major challenges, and potential solutions to PCC research. A convenience sample of 56 clinician-researchers taking care of critically ill children in LMIC was targeted. In addition, the survey was made available on a Latin American PCC website. Descriptive statistics were used for data analysis.ResultsThe majority of the 47 survey respondents worked at urban, public teaching hospitals in LMIC. Respondents stated their primary PCC research motivations were to improve clinical care and establish guidelines to standardize care. Top challenges to conducting research were lack of funding, high clinical workload, and limited research support staff. Respondent-proposed solutions to these challenges included increasing research funding options for LMIC, better access to mentors from high-income countries, research training and networks, and higher quality medical record documentation.ConclusionLMIC clinician-researchers must be better empowered and resourced to lead and influence the local and global health research agenda for critically ill children. Increased funding options, access to training and mentorship in research methodology, and improved data collection systems for LMIC PCC researchers were recognized as key needs for success

Modelling the impact and cost-effectiveness of combination prevention amongst HIV serodiscordant couples in Nigeria.

OBJECTIVE: To estimate the impact and cost-effectiveness of treatment as prevention (TasP), pre-exposure prophylaxis (PrEP) and condom promotion for serodiscordant couples in Nigeria. DESIGN: Mathematical and cost modelling. METHODS: A deterministic model of HIV-1 transmission within a cohort of serodiscordant couples and to/from external partners was parameterized using data from Nigeria and other African settings. The impact and cost-effectiveness were estimated for condom promotion, PrEP and/or TasP, compared with a baseline where antiretroviral therapy (ART) was offered according to 2010 national guidelines (CD4 <350 cells/μl) to all HIV-positive partners. The impact was additionally compared with a baseline of current ART coverage (35% of those with CD4 <350 cells/μl). Full costs (in US $2012) of programme introduction and implementation were estimated from a provider perspective. RESULTS: Substantial benefits came from scaling up ART to all HIV-positive partners according to 2010 national guidelines, with additional smaller benefits of providing TasP, PrEP or condom promotion. Compared with a baseline of offering ART to all HIV-positive partners at the 2010 national guidelines, condom promotion was the most cost-effective strategy [US$1206/disability-adjusted-life-year (DALY)], the next most cost-effective intervention was to additionally give TasP to HIV-positive partners (incremental cost-effectiveness ratio US $1607/DALY), followed by additionally giving PrEP to HIV-negative partners until their HIV-positive partners initiate ART (US$7870/DALY). When impact was measured in terms of infections averted, PrEP with condom promotion prevented double the number of infections as condom promotion alone. CONCLUSIONS: The first priority intervention for serodiscordant couples in Nigeria should be scaled up ART access for HIV-positive partners. Subsequent incremental benefits are greatest with condom promotion and TasP, followed by PrEP

High-risk human papilloma virus and cervical abnormalities in HIV-infected women with normal cervical cytology

Background: The prevalence of High-Risk Human papilloma virus (HR-HPV), a necessary cause of invasive cervical cancer (ICC) is relatively high in HIV infected women. Gaps exist in our knowledge of the optimal approaches for managing women who have HR-HPV with normal cervical cytology (NCC) particularly in settings of HIV infection. Methods: Between May 2012 and June 2013 we conducted a colposcopic assessment of HIV-infected women with prior (NCC) and known HR-HPV status to compare cervical abnormalities in women with and without HR-HPV. Colposcopic examinations were done at the Operation Stop Cervical Cancer (OSCC) unit of the Jos University Teaching Hospital (JUTH), Jos, Nigeria. Abnormal colposcopic finding (ACF) was defined as areas of aceto-white epithelium involving the squamo-coulumnar junction, areas of punctation, mosaic pattern or atypical vessels. We compared proportions of ACF as well as histologic grades of cervical intra-epithelial neoplasia (CIN) in women with or without HR-HPV. Statistical analysis was done on STATA. Results: We conducted colposcopic examinations in 78 out of 89 (86.5%) eligible women. The mean age of the cohort was 32.4 years (SD ±4.6) with a median 32 years (IQR 29–36). After a mean follow up time of 20.1 months from the initial cervical pap cytology and HR-HPV testing, we found 12 of 78 (15.4%) women with ACF. The odds for an ACF was statistically higher [OR = 4.0 (95% CI: 1.1-14.7)] in women with HR-HPV compared to those without. Of the twelve women with ACF, subsequent histologic examination of colposcopically directed cervical biopsies confirmed CIN 1 in 4 cases (33.3%), CIN 2 in 1 case (8.3%), CIN 3 in 2 cases (16.7%), carcinoma-in-situ (CIS) in 2 cases (16.7%), and normal cervix in 3 (25.0%). Overall, the proportion of women detected with any grade of CIN was 11.5% (9/78) and 6.4% (5/78) were CIN 2 or greater lesion (CIN2+). Conclusion: HIV-infected women with NCC and HR-HPV had a four-fold higher likelihood for an ACF. The practice of early colposcopic examination of HIV-infected women with prior NCC and HR-HPV may increase early detection of higher grade CIN and CIS cancer stages in our setting

Association of Bacterial vaginosis and other Sexually Transmitted Infections with HIV among pregnant women in Nigeria.

OBJECTIVES: To determine the association of Bacterial vaginosis (BV) and other sexually transmissible infections (STIs) with HIV prevalence among pregnant women in Jos, Nigeria. METHODS: This was a cross- sectional study of pregnant women who participated in the Prevention of Mother-to-Child Transmission of HIV program of the AIDS Prevention Initiative in Nigeria, between April 2002 and July 2004, at the Jos University Teaching Hospital in Jos, Nigeria. Blood, high vaginal and endocervical samples were obtained for diagnosis of HIV, BV and other STIs. Data were analyzed for prevalence of HIV, BV and other STIs. Univariate and multivariate logistic regression models generated unadjusted and adjusted odds ratios (OR) as well as 95% confidence intervals (CI) of the association of BV and other STIs with HIV prevalence. P value <0.05 was considered statistically significant. RESULTS: A total of 4,046 pregnant women were studied and 97.6% (3,950/4,046) had complete laboratory records for analysis. The prevalence of HIV was 8.2% (CI: 7.4-9.1); BV 11.9% (CI: 10.9-12.9); Candida 10.7% (CI: 9.7-11.7); mixed infection of BV and Candida 2.8% (CI: 2.3-3.4); Trichomonads 0.6% (CI: 0.3-0.8) and syphilis 0.35% (0.16-0.54). BV, Candida, mixed BV and Candida; and Trichomonads were independently associated with HIV infection [adjusted OR (95% CI), 2.9 (CI: 2.2-3.9); 2.0 (CI: 1.5-2.9); 3.4 (CI: 2.0-5.6), and 3.3 (CI: 1.1-9.7) respectively]. CONCLUSION: HIV prevalence is higher among pregnant women who have BV, Candida and Trichomonads vaginal infections compared with women who have no evidence of infection. The practice of routine screening for BV and other STIs among pregnant women as a strategy for identifying women at risk for prevalent HIV infection should be sustained/ encouraged and the syndromic management of STIs should be integrated into all antenatal care management protocols in antenatal clinics in order to curb the epidemic of heterosexual HIV transmission
