Investigating the acceptability of non-mesh, long-lasting insecticidal nets amongst nomadic communities in Garissa County, Kenya using a prospective, longitudinal study design and cross-sectional household surveys.

BACKGROUND: North East Kenya is an area of semi-arid terrain, prone to malaria epidemics. The distribution of long-lasting insecticidal nets (LLINs) has long been a key malaria intervention, however, for nomadic populations who live and sleep outside, in harsh climates and areas with increasing reports of exophagic behaviour of mosquitoes, traditional LLINs are often inadequate. This study investigates the acceptability of non-mesh LLINs, specifically designed to suit nomadic, outdoor sleeping communities. METHODS: In September 2011, 13,922 non-mesh LLINs were distributed to 8,511 nomadic households in Garissa County, North East Province, Kenya. A prospective, longitudinal study design was used to assess the acceptability of this novel type of LLIN. Cross-sectional household surveys, focus group discussions (FGDs), and key informant interviews (KIs) were used to collect data on attitudes and practices regarding the Dumuria nets. RESULTS: A very high level of acceptability was reported with 95.3% of respondents stating they liked the nets. Of the factors reportedly determining net use the most frequently mentioned was "vulnerability". Of those with concerns about the nets, the colour (white) was the most frequently reported. CONCLUSION: The tailoring of LLINs to specific communities and contexts leads to increased levels of acceptability. Large-scale, blanket net distribution campaigns, which are currently the standard practice, do not cater for the specific and nuanced needs of the differing communities they often serve. This non-mesh LLIN offers a highly effective and desirable malaria prevention option to a typically hard to reach and underserved nomadic population at increased risk of malaria infection

Patient adherence to prescribed artemisinin-based combination therapy in Garissa County, Kenya, after three years of health care in a conflict setting.

BACKGROUND: Current day malaria cases and deaths are indicative of a lack of access to both methods of prevention, diagnosis, and treatment; an important determinant of treatment efficacy is adherence. This study is a follow up to the baseline study of adherence to artemether-lumefantrine (AL) carried out in Garissa District in 2010. The study presented evaluates any changes in adherence levels which may have occurred in the area during this period and after nearly three years of sustained use of ACT across the public health sector. METHODS: The study was carried out in Garissa County in the North Eastern Province of Kenya and included patients fitting the suspected malaria case definition and having been prescribed AL, regardless of confirmatory diagnosis. A questionnaire assessed the intake of AL via both self-reporting by the participant and observation of blister packs by the interviewer. On separate occasions exit interviews with patients and observations of prescribers were also carried out. RESULTS: Of the 218 participants enrolled, 195 were successfully followed up. 60% of participants were found to be adherent to the three-day AL regimen, this is 4.7% lower than the proportion of participants adherent in 2010; the result of a two-sided z-test was not significant (p = 0.23). The odds of the patient being adherent to AL increased by 65% with each additional correct statement regarding how to take AL that a patient could recall (between zero and four statements), this was the only variable significantly associated with patient adherence (p = 0.01). CONCLUSION: Sustaining the ACT adherence rates at the 2010 levels, through 2.5 years of insecurity in the study area is an achievement and suggests that if security can be improved barriers to improving health service quality and patient adherence to AL would be removed. This study, by looking specifically at anti-malarial adherence over a prolonged period and in a setting of severe conflict, provides a valuable and rare insight in to the challenges and barriers to ACT adherence in such settings

Investigating a Non-Mesh Mosquito Net Among Outdoor Sleeping Nomadic Communities in Kenya.

Rising reports of exophagic malaria vectors make even more pressing the need for alternatives to traditional, mesh, long-lasting insecticidal nets (LLINs) designed for indoor sleeping and often inadequate in the protection of outdoor-sleeping populations. This study tests and evaluates the retention, utilization, and durability of novel, non-mesh nets designed for outdoor use. Longitudinal, cross-sectional surveys were conducted, the physical condition of nets was assessed, and bio-efficacy and insecticide content were tested. At 22 months, retention was 98.0%; 97.1% of nets fell within the World Health Organization (WHO) category of being in "good" condition; none were in the "torn" category. At 18 months post-distribution, 100% of nets had at least WHO Pesticide Evaluation Scheme (WHOPES)-acceptable levels of insecticide, this proportion was 66.7% at 22 months. This novel mosquito net has the potential to provide a durable and context-specific tool to prevent malaria among traditionally hard-to-protect and highly vulnerable populations

Coinfections of malaria and sexually transmitted and reproductive tract infections in pregnancy in sub-Saharan Africa: a systematic review and individual participant data meta-analysis protocol.

INTRODUCTION: Malaria infection and curable sexually transmitted infections and reproductive tract infections (STIs/RTIs) adversely impact pregnancy outcomes. In sub-Saharan Africa, the prevalence of malaria and curable STIs/RTIs is high and, where coinfection is common, combination interventions may be needed to improve pregnancy outcomes. The aim of this systematic review is to estimate the prevalence of malaria and curable STI/RTI coinfection during pregnancy, risk factors for coinfection and prevalence of associated adverse pregnancy outcomes. METHODS AND ANALYSIS: We will use three electronic databases, PubMed, EMBASE and Malaria in Pregnancy Library to identify studies involving pregnant women attending routine antenatal care facilities in sub-Saharan Africa and reporting malaria and curable STI/RTI test results, published in any language since 2000. We will search databases in the second quarter of 2023 and repeat the search before completion of our analyses. The first two authors will screen titles and abstracts, selecting studies that meet inclusion criteria and qualify for full-text screening. If agreement on inclusion/exclusion cannot be reached, the last author will serve as arbiter. We will extract data from eligible publications for a study-level meta-analysis. We will contact research groups of included studies and request individual participant data for meta-analysis. The first two authors will conduct a quality appraisal of included studies using the GRADE system. The last author will adjudicate if the first two authors do not agree on any appraisals. We will conduct sensitivity analyses to test the robustness of effect estimates over time (by decade and half-decade periods), geography (East/Southern Africa vs West/Central Africa), gravidity (primigravidae, secundigravidae, multigravidae), treatment type and dosing frequency, and malaria transmission intensity. ETHICS AND DISSEMINATION: We obtained ethics approval from the London School of Hygiene & Tropical Medicine (LSHTM Ethics Ref: 26167). Results of this study will be disseminated via peer-reviewed publication and presentation at scientific conferences. PROSPERO REGISTRATION NUMBER: CRD42021224294

Improving health worker performance through text messaging: A mixed-methods evaluation of a pilot intervention designed to increase coverage of intermittent preventive treatment of malaria in pregnancy in West Nile, Uganda

Poor health worker performance is a well-documented obstacle to quality service provision. Due to the increasingly widespread availability of mobile devices, mobile health (mHealth) has received growing attention as a service improvement tool. This pilot study explored feasibility, acceptability and outcomes of an mHealth intervention designed to increase coverage of intermittent preventive treatment of malaria in pregnancy (IPTp) in two districts of West Nile, Uganda. In both districts, selected health workers (N = 48) received classroom training on malaria in pregnancy. All health workers in one district (N = 49) subsequently received 24 text messages reinforcing the training content. The intervention was evaluated using a mixed-methods approach, including four focus group discussions with health workers and three in-depth interviews with district health officials, health worker knowledge assessments one month (N = 90) and six months (N = 89) after the classroom training, and calculation of IPTp coverage from participating health facilities’ (N = 16) antenatal care registers covering six months pre- and post-intervention. Complementing classroom training with text messaging was found to be a feasible, acceptable and inexpensive approach to improving health worker performance. The messages served as reminders to those who had attended the classroom training and helped spread information to those who had not. Health workers in the district where text messages were sent had significantly better knowledge of IPTp, achieving an increased composite knowledge score of 6.00 points (maximum score: 40) compared with those in the district where only classroom training was provided. Average facility coverage of three doses of IPTp was also significantly higher where text messages were sent (85.8%) compared with the district where only classroom training was provided (54.1%). This intervention shows promise for the improvement of health worker performance for delivery of IPTp, and could have significant broader application

The effect and control of malaria in pregnancy and lactating women in the Asia-Pacific region

Half of all pregnancies at risk of malaria worldwide occur in the Asia-Pacific region, where Plasmodium falciparum and Plasmodium vivax co-exist. Despite substantial reductions in transmission, malaria remains an important cause of adverse health outcomes for mothers and offspring, including pre-eclampsia. Malaria transmission is heterogeneous, and infections are commonly subpatent and asymptomatic. High-grade antimalarial resistance poses a formidable challenge to malaria control in pregnancy in the region. Intermittent preventive treatment in pregnancy reduces infection risk in meso-endemic New Guinea, whereas screen-and-treat strategies will require more sensitive point-of-care tests to control malaria in pregnancy. In the first trimester, artemether-lumefantrine is approved, and safety data are accumulating for other artemisinin-based combinations. Safety of novel antimalarials to treat artemisinin-resistant P falciparum during pregnancy, and of 8-aminoquinolines during lactation, needs to be established. A more systematic approach to the prevention of malaria in pregnancy in the Asia-Pacific is required

Global estimates of pregnancies at risk of Plasmodium falciparum and Plasmodium vivax infection in 2020 and changes in risk patterns since 2000.

BACKGROUND: Women are at risk of severe adverse pregnancy outcomes attributable to Plasmodium spp. infection in malaria-endemic areas. Malaria control efforts since 2000 have aimed to reduce this burden of disease. METHODS: We used data from the Malaria Atlas Project and WorldPop to calculate global pregnancies at-risk of Plasmodium spp. infection. We categorised pregnancies as occurring in areas of stable and unstable P. falciparum and P. vivax transmission. We further stratified stable endemicity as hypo-endemic, meso-endemic, hyper-endemic, or holo-endemic, and estimated pregnancies at risk in 2000, 2005, 2010, 2015, 2017, and 2020. FINDINGS: In 2020, globally 120.4M pregnancies were at risk of P. falciparum, two-thirds (81.0M, 67.3%) were in areas of stable transmission; 85 2M pregnancies were at risk of P. vivax, 93.9% (80.0M) were in areas of stable transmission. An estimated 64.6M pregnancies were in areas with both P. falciparum and P. vivax transmission. The number of pregnancies at risk of each of P. falciparum and P. vivax worldwide decreased between 2000 and 2020, with the exception of sub-Saharan Africa, where the total number of pregnancies at risk of P. falciparum increased from 37 3M in 2000 to 52 4M in 2020. INTERPRETATION: Historic investments in malaria control have reduced the number of women at risk of malaria in pregnancy in all endemic regions except sub-Saharan Africa. Population growth in Africa has outpaced reductions in malaria prevalence. Interventions that reduce the risk of malaria in pregnancy are needed as much today as ever

Cardiac safety of dihydroartemisinin-piperaquine and sulfadoxine pyrimethamine among pregnant women with and without asymptomatic parasitaemia in Tanzania: results from an open-label, parallel-group, randomised phase II trial

Background: Dihydroartemisinin-Piperaquine (DP) can induce transient prolongation of the corrected QT interval (QTc) and is a candidate for use with sulfadoxine-pyrimethamine (SP) in intermittent preventive treatment of malaria in pregnancy (IPTp). Pregnancy can alter pharmacokinetics of antimalarial drugs. Acute malaria infection can increase QTc prolongation. Whether DP alters cardiac function in pregnant women with or without asymptomatic parasitaemia is not well characerised. Methods: This was an open-label, parallel-group, randomised phase 2 study among pregnant women in Handeni, Tanzania (NCT02909712). Women were screened for P. falciparum by microscopy and, if positive, received a rapid diagnostic test (RDT). If RDT-positive, they received DP or SP, and the next microscopy-negative woman was randomly allocated to receive DP or SP. Enrolment and allocation continued in this alternating manner to reach 200 (50/group): Grp 1 (neg; SP), Grp 2 (pos; SP), Grp 3 (neg: DP), Grp 4 (pos: DP). Standard 12-lead ECGs were used to record cardiac function in triplicate. DP groups were measured on day 0 (predose), day 2 (predose and hours 3,4,5,6,7,8), and day 7; SP groups had day 0 (predose), and day 7 ECGs. Results: DP resulted in QTcF prolongation that peaked ~30 msec at 5-h post dose 3 on day 2 (schedule: days 0,1,2). The mean maximum increase was slightly more in group 4 compared to group 3 (33.1 vs 29.1 msec). On day 7, QTcF returned to baseline in group 3; a small and non-clinically significant increase of 3.4 (90%CI: 0.3, 6.5) msec was still present among RDT-positive women. QTcB measurements were similar. There was a marked decrease in heart rate (HR) among all DP recipients on day 2, which appeared greater in group 4 compared to group 3 (13.3 vs 8.9 bpm), baseline HR was higher in group 4 than group 3 (92.7 vs 88.5 bpm). This potentially represents a regression towards the mean. On day 7, HR had returned to baseline in both groups. Conclusion: Parasite presence did not alter the effect of DP on the different ECG parameters with the possible exception of HR. No marked differences were observed between pregnant women with and without asymptomatic parasitaemia
