Real-world effectiveness and causal mediation study of BNT162b2 on long COVID risks in children and adolescents.

Background: The impact of pre-infection vaccination on the risk of long COVID remains unclear in the pediatric population. We aim to assess the effectiveness of BNT162b2 on long COVID risks with various strains of the SARS-CoV-2 virus in children and adolescents, using comparative effectiveness methods. We further explore if such pre-infection vaccination can mitigate the risk of long COVID beyond its established protective benefits against SARS-CoV-2 infection using causal mediation analysis.

Piloting Market Food Environment Assessments in LMICs: A Feasibility Assessment and Lessons Learned.

Background: Food environments are rapidly changing in low- and middle-income countries (LMICs), leading to dietary shifts. Many gaps exist in the measurement of food environments in LMICs making it difficult to characterize the linkages between food environments and diets.

Objective: The objective of this study was to examine the feasibility of implementing USAID Advancing Nutrition's Market Food Environment Assessment (MFEA)-a suite of 7 non-resource intensive food environment assessments.

Predicting food insecurity in a pediatric population using the electronic health record.

Introduction: More than 5 million children in the United States experience food insecurity (FI), yet little guidance exists regarding screening for FI. A prediction model of FI could be useful for healthcare systems and practices working to identify and address children with FI. Our objective was to predict FI using demographic, geographic, medical, and historic unmet health-related social needs data available within most electronic health records.

Cost-Effectiveness of Intensive Blood Pressure Control in Youth With Chronic Kidney Disease.

Background: Intensive blood pressure (BP) control in youth with chronic kidney disease (CKD) slows progression, delaying the need for kidney replacement therapy (KRT). Most youth with CKD have hypertension and BP control is difficult to achieve outside of controlled experimental settings. Implementing effective BP control strategies in this population may be cost-saving despite requiring additional resources.
