Establishing Reference Intervals for Serum and Salivary Cortisol in a Selected Population in Kano, Nigeria.

Objective: Serum cortisol has long been used in the assessment of disorders of the hypothalamic-pituitary-adrenal axis. The reference interval for cortisol in both serum and saliva depends on the analytical methodology and the population studied; hence, a locally derived population-based reference interval is recommended. To our knowledge, there are no studies on reference interval determination in the study area, raising concerns about the use of reference intervals established in European and North American populations.

Impact of maternal depression on malnutrition treatment outcomes in older children with sickle cell anemia.

Background: Malnutrition and sickle cell anemia (SCA) result in high childhood mortality rates. Although maternal depression is an established risk factor for malnutrition in younger children, little is known about its impact on treatment response in children with malnutrition. We aimed to determine the relationship, if any, between maternal depression scores and malnutrition treatment outcomes in older children with SCA.

Feasibility trial for the management of severe acute malnutrition in older children with sickle cell anemia in Nigeria.

Children with sickle cell anemia (SCA) living in Nigeria are at an increased risk of malnutrition, which contributes to increased morbidity and mortality. However, evidence-based guidelines for managing malnutrition in children with SCA are lacking. To address this gap, we conducted a multicenter, randomized controlled feasibility trial to assess the feasibility and safety of treating children with SCA aged from 5 to 12 years and having uncomplicated severe acute malnutrition (body mass index z score of <-3.
