Mobile phone call reminders to improve oral rehydration salt and zinc adherence for acute diarrhea in children: a single-center, randomized controlled trial.

BACKGROUND: Low-osmolarity oral rehydration salt (ORS) and zinc therapy effectively manage diarrhea in children under five years of age, offering both short- and long-term benefits. Despite this, caregivers' adherence to ORS and zinc is often unsatisfactory due to factors such as forgetfulness, resolution of symptoms, and underestimation of the disease's severity. This study assessed the effect of mobile call reminders on ORS and zinc tablet adherence among children with acute diarrhea in a secondary-level health facility in Kwara State, Nigeria. METHODS: Using an open-label, randomized controlled trial design, this study compared caregiver-child pairs with acute diarrhea aged 6-59 months who received standard instructions (SI) alone (control group) and an intervention group (IG) who received SI plus phone call reminders on days three and seven of zinc sulfate therapy. All participants used a pictorial diary to track loose/watery stools and ORS and zinc tablet treatments for ten days. The primary outcome measures were independent and combined adherence to ORS and zinc therapy. The secondary outcomes were independent and combined adherence scores, defined as the percentage of times the ORS was given post-diarrhea and the percentage of prescribed zinc tablets administered out of ten. RESULTS: A total of 364/400 mother-child pairs completed the study. The percentage of mothers with full adherence in the intervention group was 82.5% for ORS, 72.1% for zinc, and 58.5% for combined use, compared to 78.8%, 60.8%, and 43.6%, respectively, in the control group. The odds of full adherence to ORS and zinc were 1.6 and 1.7 times higher among intervention mothers [ORS: OR = 1.561, 95% CI = 0.939-2.598, P = 0.085; zinc: OR = 1.671, 95% CI = 1.076-2.593, P = 0.022], and 1.8 times higher for combined use according to WHO guidelines [OR = 1.818, 95% CI = 1.200-2.754, P = 0.005]. The mean adherence scores for the intervention group were higher than those for the control group by 4.1% (95% CI = 0.60-7.60) for ORS, 7.3% (95% CI = 3.74-10.86) for zinc, and 5.7% (95% CI = 3.23-8.17) for the combined treatment. CONCLUSION: Phone reminders can effectively improve consistency of home treatment administered by caregivers for children under five years old. TRIAL REGISTRATION: The study was registered retrospectively (17/3/2023) with the Pan African Clinical Trial Registry (PACTR202301560735856).

Prevalence, Etiology, and Fatality Rates of Childhood Heart Failure in Nigeria: A Systematic Review and Meta-analysis.

Objectives: The objectives of the study were to describe the burden, etiology, and fatality rates of heart failure in Nigerian children. Methods: We searched PubMed database, Google scholar, TRIP database, EMBASE, African Index Medicus, and reference lists of selected articles for studies on burden, etiology, and fatality rates of heart failure in children in Nigeria published from 1977 to 2016. Two researchers reviewed the papers independently. Ten studies were selected that included 14,921 children and 1353 with heart failure. Results: The overall prevalence of heart failure using all the studies reviewed was 8.3% (95% CI: 4.9-12.6). The prevalence was 13.4% (95% CI: 10.9-16.3) in studies that excluded neonates and 4.5% (95% CI: 2.8-6.5) in studies that included neonates. The most common causes of heart failure were severe anemia (38.9%, 95% CI: 30.0-49.4), respiratory tract infections (32.4%, 95% CI: 25.5-39.7), congenital heart disease (8.4%, 95% CI: 6.8-10.2), and sepsis (7.6%, 95% CI: 3.0-14.0). The overall fatality rate was 16.0% (95% CI: 9.0 - 24.6) and was higher in studies that include neonates. Conclusion: Heart failure is common in children hospitalized in Nigeria. Its etiology is largely from non-cardiac conditions associated with severe hypoxia and mortality rates are high in children in Nigeria.

Relationships between cardiovascular signs and neurological signs in asphyxiated neonates in Ilorin, North Central Nigeria.

BACKGROUND: Perinatal asphyxia is a condition associated with multiple organ dysfunctions inclusive of cardiovascular dysfunction. Neurologic predictors of survival have been studied, but little has been reported regarding cardiovascular signs and their role in determining outcome in asphyxia. OBJECTIVE: The study aimed to determine the relationship between cardiovascular signs and outcomes in asphyxiated newborns with hypoxic ischaemic encephalopathy. METHODS: This was a cross sectional study involving asphyxiated new-born babies recruited within the first 24 hours of life. Hypoxic ischaemic encephalopathy staging was done using Sarnat and Sarnat staging. All patients had a detailed cardiovascular examination on admission, after initial resuscitation (30 - 60 minutes) into admission, and were followed till final outcome: discharge or death. RESULTS: Eighty-five asphyxiated new-borns with HIE were studied over seven months. Abnormal cardiovascular-related signs identified in the patients included respiratory distress (64.7%), small volume pulse (57.6%), hypotension (52.9%), hypoxemia (48.2%) and shock (32.9%). Five babies died. None of the clinical signs had a significant relationship with mortality. CONCLUSION: Abnormal cardiovascular signs increased with the progression of HIE staging but had no relationship with mortality.
