Our sample included 53 fetuses. Forty-seven (89%) had congenital heart disease (CHD) and 6 (11%) were diagnosed postnatally with primary lymphangiectasia. Interobserver agreement was 0.83. Pulmonary vein congestion on echocardiography was the strongest predictor of nutmeg lung (odds ratio [OR]=12.0, P=0.002). Ten fetuses reached the outcome of heart transplantation (n=1) or death (n=9) within the first 30days of life. In fetuses with CHD, survival of those with nutmeg lung was significantly lower than in those without (P<0.001). Nutmeg lung was an independent risk factor for 30-day mortality (hazard ratio [HR] 6.1, P=0.01).

Nutmeg lung pattern on fetal MRI is an independent risk factor associated with 30-day mortality in fetuses with CHD.

Traditionally, it has been used in a qualitative way, where the images are reported non-numerically by radiologists. But now MRI machines have built-in post-processing software connected to the scanner and the database of MR images. This setting enables and encourages simple quantitative analysis of MR images. In this paper, the author reviews the fundamentals of MRI and discusses the most common quantitative MRI techniques for body imaging T1, T2, T2*, T1rho and diffusion-weighted imaging (DWI). For each quantitative imaging method, this article reviews the technique, its measurement mechanism, and selected clinical applications to body imaging.Skull fractures are common in the pediatric population following head trauma and are estimated to occur post head trauma in 11% of children younger than 2 years. A skull fracture indicates potential underlying intracranial injury and might also help explain the mechanism of injury. Multiple primary and accessory sutures complicate the identification of non-depressed fractures in children younger than 2 years. Detection of linear skull fractures can be difficult on two-dimensional (2-D) CT and can be missed, particularly when the fracture is along the plane of image reconstruction. Knowledge of primary and accessory sutures as well as normal anatomical variants is of paramount importance in identifying pediatric skull fractures with a greater degree of confidence. Acute fractures appear as lucent cortical defects that do not have sclerotic borders, in contrast to sutures, which might demonstrate sclerotic margins. Three-dimensional (3-D) CT has increased sensitivity and specificity for detecting skull fractures and is essential in the evaluation of pediatric head CTs for distinguishing subtle fractures from sutural variants, especially in the setting of trauma. In this review, we present our experience of the use of 3-D reformats in head CT and its implications on the interpretation, especially in the setting of accidental or abusive head trauma.The Australian Health Economics Model of Osteoporosis (AusHEMO) has shown good face, internal and cross validities, and can be used to assist healthcare decision-making in Australia.

This study aimed to document and validate the risk engine of the Australian Health Economics Model of Osteoporosis (AusHEMO).

AusHEMO is a state-transition microsimulation model. The fracture risks were simulated using fracture incidence rates from the Dubbo Osteoporosis Epidemiology Study. The AusHEMO was validated regarding its face, internal and cross validities. Goodness-of-fit analysis was conducted and Lin's coefficient of agreement and mean absolute difference with 95% limits of agreement were reported.

The development of AusHEMO followed general and osteoporosis-specific health economics guidelines. AusHEMO showed good face validity regarding the model's structure, evidence, problem formulation and results. In addition, the model has been proven good internal and cross validities in goodness-of-fit test. Chk2 Inhibitor II nmr Lin's coefficluded. Health policy-makers in Australia can use the AusHEMO to select which osteoporosis interventions such as medications and public health interventions represent good value for money.Overweight/obesity, prevalent cardiovascular risk factors in children, can be associated with increased risk of adverse outcomes in children with heart disease. The American College of Cardiology (ACC) developed quality metrics including a BMI metric related to identifying and counseling overweight and obese children presenting to cardiology clinics. This metric was used for a multicenter collaborative learning Quality improvement (QI) Project through the ACC Quality Network (QNet). Our aim was to increase the percentage of children between ages 3 and 18 years presenting to cardiology clinics at participating centers with BMI > 85th percentile who received appropriate counseling. Participating centers submitted data quarterly to QNet for a sample of patients who received counseling. A Key Driver Diagram was created to help teams drive improvement. Individual centers customized interventions and participated in network-wide educational learning sessions about QI and shared experience. Statistical process control charts were used. From 04/01/2017 to 09/30/2019, 27,511 patient visits were included. Among 32 participating centers, overall counseling rate was 54%. The BMI counseling rate increased from 25% in 2017Q2 to 54% in 2019Q3. There was a wide variation from 10 to 100% in the performance of individual centers. The overall rate of identification and counseling of overweight and obese children presenting to ambulatory cardiology clinics in participating centers is low. There is wide variation in the performance of centers, providing an opportunity for improvement. Using this multicenter learning approach, individual centers have demonstrated improvement. This demonstrates that collaborative learning approaches in QI can increase implementation of the metric.Pulmonary artery hypertension (PAH) is a common and serious disease which is characterized by pulmonary vascular remodeling. Bosentan (BST) is the first approved oral targeted drug of endothelin-1 (ET-1) receptor antagonists for the treatment of PAH. MicroRNA-27a (miR-27a) and peroxisome proliferator-activated receptor γ (PPARγ) were found to be related to the pathogenesis of PAH. To further explore the signal transduction mechanism of BST in the treatment of PAH, we examined the effects of BST on endothelin receptors, miR-27a, and PPARγ. Meanwhile, the influence of miR-27a in the formation and development of PAH was discussed. Our results demonstrated that during the pathophysiology of PAH, miR-27a, PPARγ, and ET-1 were cross-inhibited, which indicated that the miR-27a/PPARγ/ET-1 signaling pathway was dysregulated; in addition, BST could competitively bind to ET-1 receptors and inhibit the miR-27a/PPARγ/ET-1 signaling pathway, thereby delaying the proliferation of PASMCs and affecting the development of PAH.
