ABSTRACT
OBJECTIVE: To estimate the lung ultrasound (LUS0) scores within 6 hours of birth in neonates with respiratory distress (RD) and assess its ability to predict the severity of RD. METHODS: This single-center cross-sectional study included all neonates admitted with RD during the study period for whom a LUS was performed within 6h of birth. LUS0 scoring was done by dividing the lung fields into 3 fields on either side and a score from 0 to 3 per field (maximum score 18). We excluded neonates with congenital heart disease, congenital anomalies of chest/lung, chromosomal anomalies and if the operator for LUS0 was not available. ROC curves were constructed for estimating the cut-off LUS0 score for the severity of RD in terms of the following six outcomes: fraction of inspired oxygen (FiO2) requirement >50% during first 3 days of life, need for invasive ventilation on day 3 of life, Silverman-Anderson score >7, surfactant requirement, radiological grades of RDS, and death. RESULTS: The median (IQR) LUS0 scores were significantly higher in neonates with greater severity of RD in terms of FiO2 requirement >50% during first 3 days of life [12.0, (5.0, 14.0)], need for invasive ventilation on day 3 of life [12.0 (7.5, 12.5)], Silverman-Anderson score ≥ 7 in preterm [9.5, (6.0, 12.0)], surfactant requirement [11.5, (4.0, 12.5)], radiological grades of RDS [10.0, (4.0, 12.0)], and death [12.0, (7.0, 15.0)]. In logistic regression analysis, with continuous LUS0 scores as covariates, the odds ratio significantly increased for every unit increase in LUS0 score. CONCLUSION: Early LUS0 scores can predict the prognosis and severity of neonatal RD.

OBJECTIVE: Objective To analyze the risk of premature atherosclerosis in children with transfusion-dependent thalassemia (TDT) compared to controls by measuring carotid intima-media thickness (CIMT) and correlating it with clinical and biochemical parameters. METHODS: Case-control study among children aged 2 to 15 years. RESULTS: Significantly higher CIMT values were observed across all age groups. Mean (SD) CIMT in controls were 0.27(0.07) mm, 0.39 (0.03) mm, and 0.46 (0.05) mm in 2 to 5 years, 6 to 10 years, and 11 to 15 years age groups respectively, as against 0.43 (0.08) mm, 0.55 (0.07) mm and 0.63 (0.08) mm in cases in similar age groups (P<0.001). Mean triglycerides and liver enzymes were significantly elevated in cases. Logistic regression analysis demonstrated that older age group and higher serum ferritin levels, but not dyslipidemia, were significantly associated with high CIMT. CONCLUSION: Children with TDT are at increased risk for premature atherosclerosis.
