Ultrasonography and chest X-ray are equally accurate for determination of endotracheal tube tip-to-carina in infants. As ultrasonography is more easily available and is safer than X-ray, it may be a better modality for confirming proper placement of endotracheal tube in neonates.

AbstractBackgroundNoninvasive T2* magnetic resonance imaging (MRI) assessment can stratify the risk of subsequent cardiac dysfunction in β-thalassemia major (TM) and β-thalassemia intermedia (TI) patients. The normal level of N-terminal pro B-type natriuretic peptides (NT-proBNP) can rule out acute heart failure.AimWe aim to investigate the relation of NT-proBNP level, T2* MRI, and echocardiographic findings in TM and TI patients.Materials and methodsIn this cross-sectional study, 41 TM patients, 41 TI patients, and 41 healthy individuals (HI) were enrolled. NT-proBNP level, T2* MRI, and two-dimensional echocardiography were assessed for all patients and controls.ResultsThere was statistically significant correlation between NT-proBNP levels and mitral inflow late diastolic velocity (r = −0.538; p = 0.006) in TM group. There was statistically significant correlation between NT-proBNP levels and tricuspid annulus systolic velocity (r = −0.438; p = 0.028), systolic velocity of septum (r = −0.472; p = 0.020), and mitral inflow early-to-late diastolic wave ratio (r = 0.592; p = 0.002) in TM group.ConclusionEarly diagnosis and treatment of myocardial iron overload are likely to prevent the mortality in patients with established ventricular dysfunction. Since NT-proBNP levels were not significantly increased in documented left ventricular (LV) diastolic dysfunction, this factor may not be sensitive for the detection of latent LV diastolic dysfunction in the early stages of disease progression.

Background:The parents of children with congenital heart disease (CHD) are faced with multiple needs such as home care of children and medicinal care after the child is discharged from hospital. Objectives:To assess the effect of consultancy on phone after hospital discharge on self-efficacy of mothers of children with CHD.Method: This is a quasi-experimental study in which 100 mothers were selected from among those whose children were hospitalized due to their CHD using a simple random sampling and randomly divided into control and intervention groups using block randomization: the intervention group on phone consultancy and the control group. Tools used for collecting data were the Demographic Information and General Self-Efficacy questionnaires. The principal researcher phoned mothers in the intervention group on the third and fifth days after hospital discharge and consulted with them about giving medications. Immediately after hospital discharge and one week later, questionnaires were filled out. Results:The mothers' self-efficacy score in the intervention group had a statistically significant difference immediately after hospital discharge and one week later (p=0.000, p<0.001). However, the difference in the mothers' self-efficacy score in the control group was not significant immediately after hospital discharge and one week later (p=0.421).
