This study aimed to assess in critically ill patients the relationship between muscle mass estimates obtained using minimally invasive ultrasound techniques with both minimal and maximal pressure compared with CT images at the third lumber vertebra level. All patients were treated in a single Australian intensive care unit. Eligible patients had paired assessments, within a 72-h window, of muscle mass by ultrasound (quadriceps muscle layer thickness in centimetres, with maximal and minimal pressure) and CT axial cross-sectional area (cm ). Data are presented as mean (standard deviation), median (interquartile range), and frequencies[n (%)]. Thirty-five patients [mean (standard deviation) age= 55 (16) years, median (interquartile range) body mass rrogate for CT assessment of skeletal muscle mass. Ultrasound assessment of the quadriceps muscle using maximal pressure reasonably predicts the skeletal muscle at the third lumbar vertebra level of critically ill patients. However, there is substantial uncertainty within these regression estimates, and this may reduce the current utility of this technique as a minimally invasive surrogate for CT assessment of skeletal muscle mass. to compare the antipyretic effects of ibuprofen in febrile children with serious bacterial infections (SBI), and children with a presumed viral infection. A prospective cross- sectional study was conducted in a pediatric Emergency department between October 2018 and March 2020 for children aged 3months to 4years with a rectal temperature≥38.5°C. Patients received 10mg/kg of ibuprofen oral suspension. Rectal temperature was measured 60 and 120min after administration. Laboratory and imaging
