Receipt of seasonal malaria chemoprevention by age-ineligible children and associated factors in nine implementation states in Nigeria.

BACKGROUND: As part of implementation quality standards, community distributors are expected to ensure that only age-eligible children (aged 3-59 months) receive seasonal malaria chemoprevention (SMC) medicines during monthly campaigns. There is uncertainty about the extent to which SMC medicines are administered to ineligible children. This study aimed to assess the magnitude of this occurrence, while exploring the factors associated with it across nine states where SMC was delivered in Nigeria during the 2022 round. METHODS: This analysis was based on data from representative end-of-round SMC household surveys conducted in nine SMC-implementing states in Nigeria. Data of 3299 age-ineligible children aged > 5 years and their caregivers were extracted from the survey dataset. Prevalence of receipt of SMC medicines by ineligible children was described by child-, caregiver- and SMC-related factors. Mixed-effects multivariable logistic regression models were fitted to explore the factors associated with ineligible receipt of SMC medicines. RESULTS: 30.30% (95% CI 27.80-32.90) of ineligible children sampled received at least one dose of SMC medicines in 2022, the majority (60.60%) of whom were aged 5-6 years while the rest were aged 7-10 years. There were lower odds of an age-ineligible child receiving SMC among caregivers who had knowledge of SMC age eligibility (OR: 0.53, 95% CI 0.37-0.77, p < 0.001), compared with those who were knowledgeable of age eligibility. Higher odds of receipt of SMC were found among age-ineligible children whose caregivers had higher confidence in the protective effect of SMC against malaria (OR: 2.01, 95% CI 1.07-3.72, p = 0.030), compared with those whose caregivers were less confident. Compared with ineligible children of younger caregivers (aged < 20 years), those whose caregivers were older had lower odds of receiving SMC than those whose caregivers were younger; with lower odds among children of caregivers aged 20-39 years (OR: 0.50, 95% CI 0.30-0.82, p = 0.006). CONCLUSIONS: This study contributes important evidence on the magnitude of the receipt of SMC medicines by age-ineligible children, while identifying individual and contextual factors associated with it. The findings provide potentially useful insights that can help inform and guide context-specific SMC implementation quality improvement efforts.

Urban-rural differences in seasonal malaria chemoprevention coverage and characteristics of target populations in nine states of Nigeria: a comparative cross-sectional study.

BACKGROUND: Differences between urban and rural contexts in terms of sociodemographic characteristics, geographical features and risk perceptions may lead to disparities in coverage and related outcomes of community-based preventive interventions, such as seasonal malaria chemoprevention (SMC). This study investigated urban-rural differences in SMC coverage and other programme outcomes, as well as child and caregiver characteristics of target populations in nine implementing states in Nigeria during the 2022 SMC round. METHODS: This is a comparative cross-sectional study based on comprehensive end-of-round household surveys conducted in nine states where SMC was delivered in Nigeria in 2022. Data of 11,880 caregiver-child pairs were included in the analysis. Rural-urban differences in SMC outcomes and child and caregiver characteristics were assessed, first by using Pearsons' chi-square test for independence for categorical variables. Univariate multilevel mixed-effect logistic regression models, with random intercepts for cluster units, were used to quantify the strength of association between location and each SMC coverage and related outcomes. RESULTS: Significant urban-rural differences were observed in caregivers' sociodemographic characteristics, such as age, gender, level of education, occupation status and health-seeking behaviour for febrile childhood illnesses. Disparities were also seen in terms of SMC coverage and related outcomes, with lower odds of the receipt of Day 1 dose direct observation of the administration of Day 1 dose by community distributors, receipt of the full three-day course of SMC medicines and receipt of SMC in all cycles of the annual round among children residing in urban areas, compared with those residing in rural areas. Similarly, urban-dwelling caregivers had lower odds of being knowledgeable of SMC and believing in the protective effect of SMC than rural-dwelling caregivers. CONCLUSION: Findings highlight observable urban-rural disparities in SMC programme delivery and related outcomes, as well as target population characteristics, underscoring the need for context-specific strategies to ensure optimal delivery of SMC and improve programme implementation outcomes in urban settings.

Adherence to referral advice and its associated factors among community drug distributors and caregiver during SMC implementation in nine states.

BACKGROUND: Malaria is a global public health problem that disproportionately affects under-five children in poor resource countries. Nigeria accounted for the highest burden of malaria in Western Africa. Thus, seasonal malaria chemoprevention (SMC) programmes have been recommended and have been implemented across 9 states (Bauchi, Borno, FCT, Kebbi, Kogi, Nasarawa, Plateau, Oyo and Sokoto) in Nigeria. The study aims to measure the adherence to referral protocol and its associated factors among community drug distributors (CDs) and caregivers during SMC implementation in nine states. METHODS: The data of caregiver-child pairs that were identified with fever during the cycle one SMC implementation was extracted from the End-of-cycle (EoC) surveys carried out following cycles one SMC implementation in the study states. The surveys were completed within two weeks of the completion of SMC cycle one. Mixed-effects multivariable logistic regression models were fitted to explore the factors associated with adherence to referrals among caregivers-child pairs. RESULTS: The socio-demographic characteristics of caregiver considered in the model were not found to be significantly associated with children down with fever taking to hospital for treatment, however the caregiver whose child was referred by CDs had significantly higher odds of seeking healthcare compared to those that were not referred (OR: 1.892, 95% CI 1.081-3.310, p = 0.025). There are higher odds of children seeking treatment among those that were referred by CDs. CONCLUSION: The study's findings shed light on the adherence to referral advice and the factors influencing caregiver behaviour during SMC implementation. Referral of sick child during SMC campaign appears to ensure health-seeking for malaria case management among caregivers-child peer in target communities.

Niacin-Induced Syncope in a Middle-Aged Male: When an Over-the-Counter Vitamin Goes Wrong.

Niacin is an essential vitamin with lipid-modifying properties. It is readily available in many over-the-counter (OTC) supplements. However, the use of niacin can lead to undesirable adverse reactions, including flushing, nausea, hyperglycemia, etc. Here, we present a rare case of niacin-induced syncope caused by a sudden increase in dosage in a middle-aged male. Extensive history, examination, and cardiovascular investigation were obtained to rule out various common etiologies of syncope. We also discuss the utility of niacin as a nutritional supplement, as most individuals obtain sufficient niacin intake from foods and beverages. As a treatment for dyslipidemia, niacin no longer exhibits cardiovascular benefits in the contemporary statin era. We argue that an additional niacin supplement is both unnecessary and potentially harmful. Therefore, niacin supplementation should be cautiously taken with no additional health benefits and frequent deleterious effects.
