Abstract Hypoxic‐ischemic encephalopathy (HIE) resulting from perinatal asphyxia presents a substantial risk of mortality and long‐term sequelae in neonates. Therapeutic hypothermia (TH) improves both short‐ outcomes near‐term/term neonates with moderate to severe HIE. While TH often require polypharmacy, the impact covariates on pharmacokinetics pharmacodynamics is only partially described quantified. In this pooled, multicenter retrospective study, longitudinal trends human serum albumin...

Total hip arthroplasty in dislocated developmental dysplasia is a complex, technically demanding procedure with high complication rates. Anatomic abnormalities and the young age of patients influence results. Restoration anatomic center often requires shortening femur order to avoid over-stretching neurovascular structures. We performed cementless total subtrochanteric transverse osteotomy on 44 hips 31 patients. There were 29 female 2 male The average at time operation was 43.2 (range,...

Critically ill neonates are at greater risk for adverse drug reactions (ADRs). The differentiation of ADRs from associated with organ dysfunction/immaturity or genetic variability is difficult.In this prospective cohort study, each ADR was assessed using newborn-specific severity and probability scales by the clinical pharmacist. Subsequently, a machine learning-based score designed to predict presence in neonates.In 98/412 (23.8%) (56.3%; male) included, 187 (0.42 ADR/patient) were...
