A root cause analysis of sub-optimal uptake and compliance to iron and folic acid supplementation in pregnancy in 7 districts of Zambia

Qualitative evaluation of a package of implementation strategies codesigned to support the introduction of multiple micronutrient supplementation (MMS) for pregnant women in Bamako, Mali

Mali national policy recommends that women take iron and folic acid supplements (IFA) from the time of the first antenatal care (ANC) visit, throughout pregnancy and during the first 3 months after delivery. In 2020, the World Health Organization (WHO) updated their ANC guidelines to recommend the United Nations International Multiple Micronutrient Antenatal Preparation (UNIMMAP) formulation of multiple micronutrient supplements (MMS) in the context of rigorous research, including implementation research. In Bamako, Mali, a codesign process was used to tailor antenatal care MMS packaging and counselling materials aimed at optimizing delivery and uptake of and adherence to MMS. This paper presents the codesign process along with the results of a post-intervention qualitative assessment to evaluate the behaviour change intervention. At the conclusion of the intervention, we conducted semistructured qualitative interviews with 24 women who had received the intervention and six pharmacy managers from the six health centres participating in the study. We conducted two focus groups with midwives who had delivered the intervention and two group discussions with family members of women who had received the intervention. Respondent perspectives reveal an easy experience transitioning from previously used IFA. Women and providers concur that the intervention counselling materials and visual aids were instrumental in influencing the perceived benefit and uptake of MMS. Family members play an influential role in pregnant women's decision-making regarding MMS uptake. MMS and the associated implementation strategies developed through the codesign process were found to be a highly acceptable intervention.

Assessing a Fermented Whey Beverage Biofortified with Folate as a Potential Folate Source for Humans

Folate, a vital water-soluble vitamin (B9), requires specific attention as its recommended daily intake frequently is not reached in countries without mandatory fortification. In this regard, biofortification with microorganisms like Bifidobacterium and Streptococcus offers a compelling approach for enhancing food with natural folates. A randomized, nonblinded, and monocentric human pilot study is conducted to assess the bioavailability of a folate-biofortified fermented whey beverage, comprising 3 intervention days and a controlled replenishment phase before and during the assay. Folate plasma concentration (5-CH3-H4folate) is determined using a stable isotope dilution assay and LC-MS/MS detection. Biokinetic parameters (cmax and tmax) are determined, and areas under the curve (AUC) normalized to the basal folate plasma concentration are calculated. An average bioavailability of 17.1% in relation to the 5-CH3-H4folate supplement, ranging from 0% to 39.8%, is obtained. These results reiterate the significance of additional research into folate bioavailability in general and dairy products. Further investigations are warranted into folate-binding proteins (FBP) and other potential limiting factors within the food and individual factors. In summary, biofortification via fermentation emerges as a promising avenue for enhancing the natural folate content in dairy and other food products.

The Experience of Anaemia and Ingesting Oral Iron Supplementation in Pregnancy: A Qualitative Study

INTRODUCTION

The objective of this study was to understand the experience of iron deficiency anaemia requiring oral iron in pregnancy and the factors affecting compliance with oral iron supplementation. Participants' understanding regarding the possible consequences of anaemia in pregnancy was also explored. Feedback on a proposed randomised controlled trial of daily versus alternate day oral iron in pregnancy was sought.

MATERIALS & METHODS

Following ethical approval, fourteen semi-structured one-to-one interviews were carried out using an interview tool with open-ended questions. Recruitment was carried out through social media and from an antenatal out-patient setting. Interviews were audio-recorded, transcribed and analysed thematically.

RESULTS

Fatigue emerged as a predominant and troubling symptom. Awareness was often highlighted through friends/family and from healthcare professionals, particularly in first pregnancies. Knowledge surrounding the potential short-term and long-term adverse consequences of untreated anaemia however was limited. Gastro-intestinal side-effects, a previous experience of poor tolerance and forgetfulness all negatively impacted compliance with oral iron supplementation in pregnancy. Routine, a perceived improvement in fatigue with supplementation and reduced dose frequency recurred as themes which positively affected compliance. Pregnancy as a motivating factor recurred as a theme in analysis. The role of diet was felt to be important. Knowledge of iron-rich foods and absorption aids and inhibitors was good, but practice on optimal ingestion of oral iron supplementation varied. Feedback on trial acceptability was positive with the benefit of extra supportive care noted. Incorporating study visits with routine care was advised in view of time constraints. This area of research was perceived as important.

CONCLUSION

In order to successfully reduce the rates of iron deficiency anaemia in pregnancy, it is crucial that all factors affecting compliance with oral iron are considered. Providing women with the important information on the possible consequences of sub optimally treated anaemia may help to improve this public health issue.

A systematic review of barriers and facilitators to antenatal screening for HIV, syphilis or hepatitis B in Asia: Perspectives of pregnant women, their relatives and health care providers

BACKGROUND

Despite improvements, the prevalence of HIV, syphilis, and hepatitis B remains high in Asia. These sexually transmitted infections (STIs) can be transmitted from infected mothers to their children. Antenatal screening and treatment are effective interventions to prevent mother-to-child transmission (MTCT), but coverage of antenatal screening remains low. Understanding factors influencing antenatal screening is essential to increase its uptake and design effective interventions. This systematic literature review aims to investigate barriers and facilitators to antenatal screening for HIV, syphilis, and hepatitis B in Asia.

METHODS

We conducted a systematic review by searching Ovid (MEDLINE, Embase, PsycINFO), Scopus, Global Index Medicus and Web of Science for published articles between January 2000 and June 2023, and screening abstracts and full articles. Eligible studies include peer-reviewed journal articles of quantitative, qualitative and mixed-method studies that explored factors influencing the use of antenatal screening for HIV, syphilis or hepatitis B in Asia. We extracted key information including study characteristics, sample, aim, identified barriers and facilitators to screening. We conducted a narrative synthesis to summarise the findings and presented barriers and facilitators following Andersen's conceptual model.

RESULTS

The literature search revealed 23 articles suitable for inclusion, 19 used quantitative methods, 3 qualitative and one mixed method. We found only three studies on syphilis screening and one on hepatitis B. The analysis demonstrates that antenatal screening for HIV in Asia is influenced by many barriers and facilitators including (1) predisposing characteristics of pregnant women (age, education level, knowledge) (2) enabling factors (wealth, place of residence, husband support, health facilities characteristics, health workers support and training) (3) need factors of pregnant women (risk perception, perceived benefits of screening).

CONCLUSION

Knowledge of identified barriers to antenatal screening may support implementation of appropriate interventions to prevent MTCT and help countries achieve Sustainable Development Goals' targets for HIV and STIs.

Comparison of Masimo Total Hemoglobin SpHb® continuous non-invasive hemoglobin monitoring device with laboratory complete blood count measurement using venous sample: Protocol for an observational substudy of the Pregnancy Risk and Infant Surveillance and Measurement Alliance Maternal and Newborn Health (PRISMA MNH) study

Background

The Masimo Total Hemoglobin SpHb® is a continuous and non-invasive handheld device to measure hemoglobin levels. Previous research has found that SpHb is able to accurately detect hemoglobin levels in adult patients with a similar degree of bias and standard deviation to point-of-care invasive method measurements. Generally, limited clinical evidence, lack of validation of Masimo at higher than and lower than hemoglobin threshold values, and scientific consensus supporting the use of Masimo for accurate hemoglobin testing for the diagnosis of anemia during pregnancy calls for further research.

Methods and analysis

The proposed prospective cohort will be nested within the ongoing Pregnancy Risk and Infant Surveillance and Measurement Alliance (PRISMA) Maternal and Newborn Health (MNH) study. Three study sites (located in Zambia, Kenya, and Pakistan) will participate and collect hemoglobin data at five time points (<20 weeks, 20 weeks, 28 weeks, 36 weeks' gestation, and six weeks postpartum). We will measure hemoglobin using a venous blood sample via hematology auto-analyzer complete blood count (gold standard) and the non-invasive device. The primary objective is to assess agreement between Masimo total hemoglobin and complete blood count and on a continuous scale using Intraclass Correlation Coefficient and Bland-Altman Analysis. The second objective is to assess agreement between the two measures on a binary scale using Positive Percentage Agreement and Negative Percentage Agreement, Cohen's Kappa, and McNemar Test. On an ordinal scale, agreement will be measured using Weighted Cohen's Kappa and Harrel's Concordance Index. Lastly, we will assess factors that might affect the accuracy of Masimo total hemoglobin using linear mixed models.

Conclusions

The primary aim of this study is to assess the validity of the non-invasive Masimo device compared to the gold standard method of invasive hemoglobin measurements during pregnancy and postpartum periods for the diagnosis of anemia.

The Application of Systems Thinking to the Prevention and Control of Sexually Transmissible Infections among Adolescents and Adults: A Scoping Review

Systems thinking is a mechanism for making sense of complex systems that challenge linear explanations of cause-and-effect. While the prevention and control of sexually transmissible infections (STIs) has been identified as an area that may benefit from systems-level analyses, no review on the subject currently exists. The aim of this study is to conduct a scoping review to identify literature in which systems thinking has been applied to the prevention and control of STIs among adolescent and adult populations. Joanna Briggs Institute guidelines for the conduct of scoping reviews were followed. Five databases were searched for English-language studies published after 2011. A total of n = 6102 studies were screened against inclusion criteria and n = 70 were included in the review. The majority of studies (n = 34) were conducted in African nations. Few studies focused on priority sub-populations, and 93% were focused on HIV (n = 65). The most commonly applied systems thinking method was system dynamics modelling (n = 28). The review highlights areas for future research, including the need for more STI systems thinking studies focused on: (1) migrant and Indigenous populations; (2) conditions such as syphilis; and (3) innovations such as pre-exposure prophylaxis and at-home testing for HIV. The need for conceptual clarity around 'systems thinking' is also highlighted.

Identifying barriers to ART initiation and adherence: An exploratory qualitative study on PMTCT in Zambia

Background

Though antiretroviral therapy (ART) is widely available, HIV positive pregnant women in Zambia are less likely to start and remain on therapy throughout pregnancy and after delivery. This study sought to understand readiness to start ART among HIV pregnant women from the perspectives of both women and men in order to suggest more holistic programs to support women to continue life-long ART after delivery.

Methods

We conducted a qualitative study with HIV positive pregnant women before and after ART initiation, and men with female partners, to understand readiness to start lifelong ART. We conducted 28 in-depth interviews among women and 2 focus group discussions among male partners. Data were transcribed verbatim and analyzed in NVivo 12 using thematic analysis. Emerging themes from the data were organized using the social ecological framework.

Results

Men thought of their female partners as young and needing their supervision to initiate and stay on ART. Women agreed that disclosure and partner support were necessary preconditions to ART initiation and adherence and, expressed fear of divorce as a prominent barrier to disclosure. Maternal love and desire to look after one’s children instilled a sense of responsibility among women which motivated them to overcome individual, interpersonal and health system level barriers to initiation and adherence. Women preferred adherence strategies that were discrete, the effectiveness of which, depended on women’s intrinsic motivation.

Conclusion

The results support current policies in Zambia to encourage male engagement in ART care. To appeal to male partners, messaging on ART should be centered on emphasizing the importance of male involvement to ensure women remain engaged in ART care. Programs aimed at supporting postpartum ART adherence should design messages that appeal to both men’s role in couples’ joint decision-making and women’s maternal love as motivators for adherence.

Pediatric hydrocephalus outcomes in Lusaka, Zambia

OBJECTIVE

Hydrocephalus is a global disease that disproportionally impacts low- and middle-income countries. Limited data are available from sub-Saharan Africa. This study aims to be the first to describe pediatric hydrocephalus epidemiology and outcomes in Lusaka, Zambia.

METHODS

This retrospective cohort study included patients < 18 years of age who underwent surgical treatment for hydrocephalus at Beit-CURE Hospital and the University Teaching Hospital in Lusaka, Zambia, from August 2017 to May 2019. Surgeries included ventriculoperitoneal shunt insertions, revisions, and endoscopic third ventriculostomies (ETVs) with or without choroid plexus cauterization (CPC). A descriptive analysis of patient demographics, clinical presentation, and etiologies was summarized, followed by a multivariable analysis of mortality and 90-day complications.

RESULTS

A total of 378 patients met the inclusion criteria. The median age at first surgery was 5.5 (IQR 3.1, 12.7) months, and 51% of patients were female (n = 193). The most common presenting symptom was irritability (65%, n = 247), followed by oculomotor abnormalities (54%, n = 204). Postinfectious hydrocephalus was the predominant etiology (65%, n = 226/347), and 9% had a myelomeningocele (n = 32/347). It was the first hydrocephalus surgery for 87% (n = 309) and, of that group, 15% underwent ETV/CPC (n = 45). Severe hydrocephalus was common, with 42% of head circumferences more than 6 cm above the 97th percentile (n = 111). The median follow-up duration was 33 (IQR 4, 117) days. The complication rate was 20% (n = 76), with infection being most common (n = 29). Overall, 7% of the patients died (n = 26). Postoperative complication was significantly associated with mortality (χ2 = 81.2, p < 0.001) with infections and CSF leaks showing the strongest association (χ2 = 14.6 and 15.2, respectively, p < 0.001). On adjusted multivariable analysis, shunt revisions were more likely to have a complication than ETV/CPC or primary shunt insertions (OR 2.45 [95% CI 1.26-4.76], p = 0.008), and the presence of any postoperative complication was the only significant predictor of mortality (OR 42.9 [95% CI 12.3-149.1], p < 0.001).

CONCLUSIONS

Pediatric postinfectious hydrocephalus is the most common etiology of hydrocephalus in Lusaka, Zambia, which is similar to other countries in sub-Saharan Africa. Most children present late with neglected hydrocephalus. Shunt revision procedures are more prone to complication than ETV/CPC or primary shunt insertion, and postoperative complications represent a significant predictor of mortality in this population.

Surgical Outcomes after Myelomeningocele Repair in Lusaka, Zambia

OBJECTIVE

Spina bifida disproportionally affects low-and-middle-income countries. We describe myelomeningocele surgical outcomes in Zambia and predictors of postoperative complications and mortality.

METHODS

This 2-center retrospective cohort study includes children who underwent surgical treatment for myelomeningocele in Lusaka, Zambia from 2017 to 2019. Primary outcomes included mortality and 30-day postoperative complications.

RESULTS

Seventy-five patients were identified. Median age at first neurosurgical evaluation was 9 days (interquartile range [IQR], 6-21) and at surgery was 21 days (IQR 15-36). Lumbosacral myelomeningocele was most common (73%, n = 54). At first preoperative evaluation, 28% of the neural tube defects were deemed infected (n = 21), and 30% were leaking cerebrospinal fluid (n = 21). Postoperatively, 7% of patients died (n = 5), whereas 31% experienced a complication (n = 23). Most common complications included wound dehiscence (n = 10, 42%) and wound purulence (n = 6, 25%). Median follow-up duration was 41 days (IQR, 6-128). On univariable analysis, mortality was significantly associated with shorter follow-up duration (5 days [IQR, 2-7] vs. 46 days [IQR, 12-132]; P = 0.02) and any complication (P < 0.001). No variable was significantly associated with postoperative complication; however, 2 variables that notably neared significance were preoperative infection of the lesion (P = 0.05) and longer surgical delay (P = 0.06).

CONCLUSIONS

Most patients born with myelomeningocele in Zambia present for first neurosurgical evaluation after 1 week of age. Preoperative infection of the lesion and postoperative complications are relatively common, and complications are a significant predictor of postoperative mortality. Further investigation into preoperative efforts to mitigate risk of postoperative complications and mortality is warranted.
