Impact of mobile technologies on cervical cancer screening practices in Lagos, Nigeria (mHealth-Cervix): Protocol for a randomised controlled trial

Background: Incidence and mortality from cervical cancer have remained high due to many obstacles facing the implementation of organized screening programs in resource-constrained countries such as Nigeria. The application of mobile technologies (mHealth) to health services delivery has the potential to reduce inequalities, empower patients to control their health, and improve the cost-effectiveness of health care delivery. Aim: To assess the efficacy of mobile technology intervention on Pap test screening adherence compared to a control condition and also determine the factors affecting the uptake of Pap smear screening practices among women in Lagos. Methods: This is a multi-center randomized controlled trial that will involve women aged 25 to 65 years attending the General Outpatient clinics of the two tertiary health institutions in Lagos, Nigeria between April and December 2020. At baseline, a total of 200 National Health Insurance Scheme (NHIS) enrollees will be randomized to either a text message arm or usual care (control) arm. The primary outcome is the completion of a Pap smear within 6 months of enrolment in the study. The associations between any two groups of continuous variables will be tested using the independent sample t-test (normal distribution) or the Mann-Whitney U test (skewed data) and that of two groups of categorical variables with Chi-square X2or Fisher's exact test where appropriate. Using binary logistic regression model, we will adjust for age and other relevant sociodemographic and clinical variables and adherence to Pap test screening. Statistical significance will be defined as P-value less than 0.05. Discussion: The mHealth-Cervix study will evaluate the impact of mobile technologies on cervical cancer screening practices in Lagos, Nigeria as a way of contributing to the reduction in the wide disparities in cervical cancer incidence through early detection facilitated using health promotion to improve Pap smear screening adherence.

Project OPUS: Development and evaluation of an electronic platform for pain management education of medical undergraduates in resource-limited settings

Introduction Pain is a very frequent symptom that is reported by patients when they present to health professionals but remains undertreated or untreated, particularly in low-resource settings including Nigeria. Lack of training in pain management remains the most significant obstacle to pain treatment alongside an inadequate emphasis on pain education in undergraduate medical curricula, negatively impacting on subsequent care of patients. This study aimed to determine the effect of a 12-week structured e-Learning course on the knowledge of pain management among Nigerian undergraduate medical students. Methods Prospective, multisite, pre-post study conducted across five medical colleges in Nigeria. Structured modules covering aspects of pain management were delivered on an e-Learning platform. Pre- and post-test self-assessments were carried out in the 12-week duration of the study. User experience questionnaires and qualitative interviews were conducted via instant messaging to evaluate user experiences of the platform. User experience data was analysed using the UEQ Data Analysis Tool and Framework Analysis. Results A total of 216 of 659 eligible students completed all sections of the e-Learning course. Participant mean age was 23.52 years, with a slight female predominance (55.3%). Across all participants, an increase in median pre- and post-test scores occurred, from 40 to 60 (Z = 11.3, p<0.001, effect size = 1.3), suggestive of increased knowledge acquisition relating to pain management. Participants suggested e-Learning is a valuable approach to delivering pain education alongside identifying factors to address in future iterations. Conclusion e-Learning approaches to pain management education can enhance traditional learning methods and may increase students’ knowledge. Future iterations of e-Learning approaches will need to consider facilitating the download of data and content for the platform to increase user uptake and engagement. The platform was piloted as an optional adjunct to existing curricula. Future efforts to advocate and support integration of e-Learning for pain education should be two-fold; both to include pain education in the curricula of medical colleges across Nigeria and the use of e-Learning approaches to enhance teaching where feasible.

Iron Accumulation with Age, Oxidative Stress and Functional Decline

Identification of biological mediators in sarcopenia is pertinent to the development of targeted interventions to alleviate this condition. Iron is recognized as a potent pro-oxidant and a catalyst for the formation of reactive oxygen species in biological systems. It is well accepted that iron accumulates with senescence in several organs, but little is known about iron accumulation in muscle and how it may affect muscle function. In addition, it is unclear if interventions which reduced age-related loss of muscle quality, such as calorie restriction, impact iron accumulation. We investigated non-heme iron concentration, oxidative stress to nucleic acids in gastrocnemius muscle and key indices of sarcopenia (muscle mass and grip strength) in male Fischer 344 X Brown Norway rats fed ad libitum (AL) or a calorie restricted diet (60% of ad libitum food intake starting at 4 months of age) at 8, 18, 29 and 37 months of age. Total non-heme iron levels in the gastrocnemius muscle of AL rats increased progressively with age. Between 29 and 37 months of age, the non-heme iron concentration increased by approximately 200% in AL-fed rats. Most importantly, the levels of oxidized RNA in gastrocnemius muscle of AL rats were significantly increased as well. The striking age-associated increase in non-heme iron and oxidized RNA levels and decrease in sarcopenia indices were all attenuated in the calorie restriction (CR) rats. These findings strongly suggest that the age-related iron accumulation in muscle contributes to increased oxidative damage and sarcopenia, and that CR effectively attenuates these negative effects

Seroprevalence of Hepatitis B Virus Infection among Pregnant Women at the Antenatal Booking Clinic of a Tertiary Hospital in Lagos Nigeria

Objectives: The objectives were to determine the seroprevalence of hepatitis B virus (HBV) infection and assess the major risk factors among Nigerian pregnant women.Subjects and Methods: This was a cross‑sectional descriptive study carried out among pregnant women at the antenatal clinic of a Tertiary Hospital in Lagos, Nigeria. A total number of 150 consenting pregnant women were selected for the study. A structured pretested interviewer‑administered questionnaire was used for the data collection. Sera were collected and tested for hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg).Results: Of the150 women screened during the study, 11 (7.3%) were seropositive for HBsAg. Of these 11 women, 4 (36.4%) were also positive for HBeAg. There was no statistically significant difference in the mean ages of participants who were seropositive for HBsAg and those who were negative for the virus (P = 0.888). There were statistically significant differences in the seroprevalence of HBsAg recorded among respondents with previous surgery (odd ratio [OR] ‑ 2.97; 95% confidence interval [CI] ‑ 1.08‑16.67; P = 0.046), previously affected sibling or spouse (OR ‑ 5.03; 95% CI ‑ 1.11–25.27; P = 0.001) and those with two or more lifetime sexual partners (OR ‑ 4.11; 95% CI ‑ 2.85–9.22; P = 0.024).Conclusion: The sero‑prevalence rate of HBV infection and also its infectivity is high in Lagos, Nigeria. These findings thus support the need for a nationwide policy of routine and widespread HBV screening among pregnant women.Keywords: Hepatitis B Surface Antigen, Hepatitis B Virus, Infectivity, Lagos, Nigeria, Seroprevalenc

Impact of Mobile Technologies on Cervical Cancer Screening Practices in Lagos, Nigeria (mHealth-Cervix): A Randomized Controlled Trial

PURPOSE: We assessed the impact of mHealth on Pap test screening uptake and also determined the factors that affect screening uptake among women in Lagos, Nigeria. MATERIALS AND METHODS: A randomized controlled trial was carried out among women in two tertiary health institutions in Lagos, Nigeria, between July 2020 and March 2021. Participants were randomly assigned to either a text message (mHealth) intervention or usual care arm. The main study outcome was the uptake of Pap smear testing within 6 months of enrollment in the study. We tested the associations between two groups of continuous variables using the unpooled independent-sample t-test (normal distribution) and that of two groups of categorical variables with the chi-square (χ2) test. Using a multinomial logistic regression model, we adjusted for relevant sociodemographic and clinical predictors of uptake of Pap smear screening. Statistical significance was defined as P < .05. RESULTS: There was a significantly higher rate of uptake of Pap smear screening among women in the mHealth arm compared with those in the usual care arm (51.0% v 35.7%, P = .031). Following adjustment in the final multivariate model, level of income (odds ratio [OR] = 5.13, 95% CI, 1.55 to 16.95), awareness of Pap smear (OR = 16.26; 95% CI, 2.49 to 76.64), General Outpatient clinic attendance, and introduction of mHealth intervention during follow-up (OR = 4.36; 95% CI, 1.44 to 13.22) were the independent predictors of Pap smear uptake. CONCLUSION: The use of mHealth technologies intervention via short-text message services is a feasible solution for cervical cancer prevention in low- and middle-income countries, and thus, the widespread use of mHealth services by health care providers and policymakers could contribute to the implementation of cervical cancer prevention services in Nigeria and in the settings of other low- and middle-income countries
