Development of paediatric critical care in northwestern Nigeria: Initial implementation with a needs assessment model.

INTRODUCTION: There is high paediatric morbidity and mortality in northwestern Nigeria, attributable in part to vaccine-preventable illnesses and lack of comprehensive training of medical and nursing staff in the healthcare delivery of paediatric critical care. Pediatric Universal Life-Saving Effort Inc. (PULSE), a New York-based nonprofit organisation with a mission to develop paediatric critical care in resource-limited settings, collaborated with Aminu Kano University Teaching Hospital to decrease the gaps in knowledge and skills of medical and nursing personnel. The joint effort also aims to address and remove barriers to the delivery of paediatric critical care in northwestern Nigeria. The primary objective was to perform a needs assessment for paediatric intensive care resources in northwestern Nigeria, identify barriers to delivering these services, and designate a hub for the development of paediatric critical care educational programs for healthcare professionals. METHODS: An anonymous survey was designed and distributed using SurveyMonkey® online software to medical and nursing staff from nine healthcare institutions in northwestern Nigeria. RESULTS: Analysis from 67 responses revealed that care delivered to critically ill paediatric patients was by anaesthesiologists (77%), pediatricians (26%), and adult intensive care specialists (10%). The acquisition of clinical skills was perceived to be an essential need (65%), followed by adequate staffing of critical care units (19%), continuing medical and nursing education (13%), and availability of medical equipment (3%). DISCUSSION: There is an identified need for paediatric critical care training and resources in northwestern Nigeria. CONCLUSION: The needs assessment conducted has provided important results that will form the basis for building staff capacity and training programs for paediatric critical care in northwestern Nigeria.

Interstitial lung disease in children with Rubinstein-Taybi syndrome.

INTRODUCTION: Rubinstein-Taybi syndrome (RSTS) is a rare genetic syndrome caused primarily by a mutation in the CREBBP gene found on chromosome 16. Patients with RSTS are at greater risk for a variety of medical problems, including upper airway obstruction and aspiration. Childhood interstitial lung disease (ILD) thus far has not been definitively linked to RSTS. Here we present three patients with RSTS who developed ILD and discuss possible mechanisms by which a mutation in CREBBP may be involved in the development of ILD. METHODS: Routine hematoxylin and eosin staining was performed on lung biopsy tissue for histological analysis. Immunofluorescent staining was performed on lung biopsy tissue for markers of fibrosis, surfactant deficiency and histone acetylation. Cases 1 and 2 had standard clinical microarray analysis. Case 3 had whole exome sequencing. Bioinformatics analyses were performed to identify possible causative genes using ToppGene. RESULTS: Computed tomography images in all cases showed consolidated densities overlying ground glass opacities. Lung histopathology revealed accumulation of proteinaceous material within alveolar spaces, evidence of fibrosis, and increased alveolar macrophages. Immunofluorescent staining showed increase in surfactant protein C staining, patchy areas of increased anti-smooth muscle antibody staining, and increased staining for acetylated histone 2 and histone 3 lysine 9. DISCUSSION: Clinical characteristics, radiographic imaging, lung histopathology, and immunofluorescent staining results shared by all cases demonstrated findings consistent with ILD. Immunofluorescent staining suggests two possible mechanisms for the development of ILD: abnormal surfactant metabolism and/or persistent activation of myofibroblasts. These two pathways could be related to dysfunctional CREBBP protein.

Particulate matter exposure predicts residence in high-risk areas for community acquired pneumonia among hospitalized children.

Particulate matter exposure is a risk factor for lower respiratory tract infection in children. Here, we investigated the geospatial patterns of community-acquired pneumonia and the impact of PM2.5 (particulate matter with an aerodynamic diameter ≤2.5 µm) on geospatial variability of pneumonia in children. We performed a retrospective analysis of prospectively collected population-based surveillance study data of community-acquired pneumonia hospitalizations among children <18 years residing in the Memphis metropolitan area, who were enrolled in the Centers for Disease Control and Prevention sponsored Etiology of Pneumonia in the Community (EPIC) study from January 2010 to June 2012. The outcome measure, residence in high- and low-risk areas for community-acquired pneumonia, was determined by calculating pneumonia incidence rates and performing cluster analysis to identify areas with higher/lower than expected rates of community-acquired pneumonia for the population at risk. High PM2.5 was defined as exposure to PM2.5 concentrations greater than the mean value (>10.75 µg/m3), and low PM2.5 is defined as exposure to PM2.5 concentrations less than or equal to the mean value (≤10.75 µg/m3). We also assessed the effects of age, sex, race/ethnicity, history of wheezing, insurance type, tobacco smoke exposure, bacterial etiology, and viral etiology of infection. Of 810 (96.1%) subjects with radiographic community-acquired pneumonia, who resided in the Memphis metropolitan area and had addresses which were successfully geocoded (Supplementary Figure F2), 220 (27.2%) patients were identified to be from high- (n = 126) or low-risk (n = 94) community-acquired pneumonia areas. Community-acquired pneumonia in Memphis metropolitan area had a non-homogenous geospatial pattern. PM2.5 was associated with residence in high-risk areas for community-acquired pneumonia. In addition, children with private insurance and bacterial, as opposed to viral, etiology of infection had a decreased risk of residence in a high-risk area for community-acquired pneumonia. The results from this paper suggest that environmental exposures as well as social risk factors are associated with childhood pneumonia.

Trauma injury, severity, and outcomes among pediatric American Indian/Alaska Natives in the North Central United States.

BACKGROUND: There is a disproportionately higher trauma morbidity between American Indian/Alaska Native (AI/AN) and non-AI/AN children. OBJECTIVE: To characterize and compare trauma in AI/AN and non-AI/AN children presenting to a Regional Pediatric Level II Trauma Center (Adult Level I Trauma Center). METHOD: A retrospective observational study of all children <20 years presenting from 2012-2018. Descriptive data were analyzed along with T-tests to determine if demographic and clinical characteristics were different for AI/AN and non-AI/AN children. RESULTS: AI/AN children are more likely to be referred from outside hospitals [OR 5.61, 95% CI 3.79, 8.29], to have penetrating injuries [OR 3.87, 95% CI 1.88, 7.99] and have higher likelihood of both minor [OR 1.48, 95% Cl 1.06, 2.07] and major [OR 1.99, 95% Cl 1.37, 2.87] trauma activation on arrival. More AI/AN children suffer violent injuries [OR 3.12, 95% CI 1.90, 5.01], utilized Intensive Care Unit (ICU) [OR 1.54 95% CI 1.10, 2.14], had prolonged length of stay (LOS) [OR 1.52, 95% Cl 1.28, 1.80], and were less likely discharged home [OR 0.65, 95% Cl 0.44, 0.96]. CONCLUSIONS: AI/AN pediatric trauma patients suffer higher morbidity compared to non-AI/AN pediatric trauma patients. This study provides data which supports the need for future interventions to decrease the burden of injury noted among AI/AN children. STUDY TYPE: Treatment STUDY TYPE AND LEVEL OF EVIDENCE: Retrospective comparative study; Level III.
