A correlation analysis of BroselowTM Pediatric Emergency Tape-determined pediatric weight with actual pediatric weight in India

BACKGROUND:The Broselow?Pediatric Emergency Tape indicates standardized,precalculated medication doses,dose delivery volumes,and equipment sizes using color-coded zones based on height-weight correlations.The present study attempted to provide more evidence on the effectiveness of the Broselow?Pediatric Emergency Tape by comparing the tape-estimated weights with actual weights.We hypothesized that the Broselow?Pediatric Emergency Tape would overestimate weights in Indian children aged<10 years,leading to inaccurate dosing and equipment sizing in the emergency setting.METHODS:This prospective study of pediatric patients aged<10 years who were divided into three groups based on actual body weight:<10 kg,10–18 kg,and>18 kg.We calculated the percentage difference between the Broselow-predicted weight and the measured weight as a measure of tape bias.Concordant results were those with a mean percent difference within 3%.Standard deviation was measured to determine precision.Accuracy was determined as color-coded zone prediction and measured weight concordance,including the percentage overestimation by 1–2 zones.RESULTS:The male-to-female ratio of the patients was 1.3:1.Total agreement between colorcoding was 63.18%(κ=0.582).The Broselow?color-coded zone agreement was 74.8%in the<10kg group,61.24%in the 10–18 kg group,and 53.42%in the>18 kg group.CONCLUSIONS:The Broselow?Pediatric Emergency Tape showed good evidence for being more reliable in children of the<10 kg and 10–18 kg groups.However,as pediatric weight increased,predictive reliability decreased.This raises concerns over the use of the Broselow?Pediatric Emergency Tape in Indian children because body weight was overestimated in those weighing>18 kg.

HbA_(1C) as a Biomarker of Non-alcoholic Fatty Liver Disease: Comparison with Anthropometric Parameters

Background and Aims:Multiple non-invasive methods including radiological,anthropometric and biochemical markers have been reported with variable performance.The present study assessed glycosylated hemoglobin(HbA1C)as a biomarker to predict non-alcoholic fatty liver disease(NAFLD)and its severity,compared with body mass index(BMI),waist to hip ratio(WHR)and waist circumference(WC)Methods:This case control study included 450 individuals,including 150 cases and 300 age-and gender-matched controls recruited from the Dow Radiology Institute on the basis of radiological findings of fatty infiltration on abdominal ultrasound through convenient sampling.BMI,WHR and WC were measured according to standard protocols.HbA1C was determined by turbidimetric inhibition immunoassay Results:Among the cases and controls,66%and 32%had HbA1C levels higher than 5.7%respectively.HbA1C and BMI were significantly associated with NAFLD[crude odds ratio(cOR)=4.12,2.88,2.25(overweight)and 4.32(obese)].WC was found to be significantly associated with NAFLD for both genders(cOR in males=5.50 and females=5.79,p<0.01).After adjustment for other parameters,HbA1C and WC were found to be significantly associated with NAFLD(aOR=3.40,p<0.001)along with WC in males(aOR=2.91,p<0.05)and in females(aOR=4.28,p<0.05).A significant rise in severity of hepatic steatosis was noted with increases in HbA1C,BMI and WC.HbA1C possessed a positive predictive value of 76%for the study population[0.76,confidence interval(CI):0.715-0.809],70.6%for males(0.706,CI:0.629-0.783)and 80%for females(0.80,CI:0.741-0.858).Conclusions:Higher than normal HbA1C and WC measurements possess a more than 70%potential to predict NAFLD.It is the single risk factor that is strongly associated with NAFLD after adjustment for indices of body measurements.HbA1C may be presented as a potential biomarker for NAFLD in examination with other anthropometric measures in the adult population.
