Biochemical Screening for Pulmonary Hypertension in Preterm Infants with Bronchopulmonary Dysplasia

BACKGROUND: Pulmonary hypertension (PH) in infants with bronchopulmonary dysplasia (BPD) is associated with increased morbidity and mortality. Elevated levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and decreased levels of amino acid precursors of nitric oxide (NO) have been associated with PH, but have not been studied in infants with PH secondary to BPD.OBJECTIVE: The aim of thi

Three-Dimensional Evaluation of Aortic Valve Annular Shape in Children With Bicuspid Aortic Valves and/or Aortic Coarctation Compared With Controls

Bicuspid aortic valve (BAV) is the most common congenital cardiac abnormality, occurring in 1% to 2% of the general population. Adults with degenerative aortic valve (AV) disease have been shown to have an elliptical shaped AV annulus. The goal of this study was to investigate the shape of the aortic annulus in children with BAV, coarctation of the aorta (CoA) with or without BAV, and normal contr

Aortic stiffness and left ventricular diastolic function in children with well-functioning bicuspid aortic valves

AIMS: Aortic stiffness and diastolic function are abnormal in adults with bicuspid aortic valves (BAVs). The goal of this study was to determine the relationship between aortic stiffness and left ventricular (LV) diastolic impairment in children with well-functioning BAV and no associated congenital heart disease.METHODS AND RESULTS: This is a retrospective review of echocardiograms in children wi

Left Ventricular End-Systolic Eccentricity Index for Assessment of Pulmonary Hypertension in Infants

BACKGROUND: Pulmonary hypertension (PH) is a common problem in the neonatal intensive care unit and is associated with significant morbidity and mortality. The aim of this study was to identify a quantitative echocardiographic marker of septal curvature that can be used to accurately identify PH in NICU infants with concern for PH.METHODS: Echocardiograms of infants who were prematurely born and i

Prevalence of post-thrombotic syndrome after cardiac catheterization

BACKGROUND: As the survival of children with cardiac disease increases, chronic complications of deep venous thrombosis from cardiac catheterization, particularly post-thrombotic syndrome, may be important to monitor for and treat, if needed. We aimed to determine the prevalence of this syndrome in children who underwent cardiac catheterization.PROCEDURE: We conducted a cross-sectional study of ch

Atenolol versus losartan in children and young adults with Marfan's syndrome

BACKGROUND: Aortic-root dissection is the leading cause of death in Marfan's syndrome. Studies suggest that with regard to slowing aortic-root enlargement, losartan may be more effective than beta-blockers, the current standard therapy in most centers.METHODS: We conducted a randomized trial comparing losartan with atenolol in children and young adults with Marfan's syndrome. The primary outcome w

Association between right ventricular dysfunction and restrictive lung disease in childhood cancer survivors as measured by quantitative echocardiography

BACKGROUND: Restrictive lung disease is a complication in childhood cancer survivors who received lung-toxic chemotherapy and/or thoracic radiation. Left ventricular dysfunction is documented in these survivors, but less is known about right ventricular (RV) function. Quantitative echocardiography may help detect subclinical RV dysfunction. The aim of this study was to assess RV function quantitat

The Origins of China's Economic Transition

In the early 1950s China adopted a Stalinist development strategy and transferred a vast amount of farm surplus into investment in state-owned heavy industry. This created a typical dual economy with heavy industry on one side and agriculture, with its huge surplus of labor, on the other, and in between a vacuum: a lack of the development of light industry. Around 1980, the state increased the pri

Resistivity imaging as a tool for rock quarry planning

In the aggregate industry the use of geophysical measuring is rare. The aim of this project is to investigate how geophysical instruments can be a tool in prospecting for rock quarries, and also how they can be a help in which direction they should expand in. To have control over the quality of the aggregates is important and therefore to know when the rock mass is changing is of interest for the

Interrater agreement of EEG interpretation in comatose post cardiac arrest patients

Question: What is the interrater agreement of EEG interpretation in adult comatose post cardiac arrest patients using the American Clinical Neurophysiology Society (ACNS) standardized critical care EEG terminology? Methods: The EEG-data were obtained from patients included in the Target Temperature Management trial (TTM), an international, multicenter, clinical trial of temperature management in c

Variability in the Diagnosis of Surgical Site Infections After Full-Thickness Skin Grafting : An International Survey

BACKGROUND: Diagnosis of a surgical site infection (SSI) in dermatologic surgery can be entirely based on a subjective assessment according to the 4th criterion of the most common definition of an SSI, which was established by the US Centers for Disease Control (CDC).OBJECTIVES: To investigate the interobserver agreement between dermatologists in their diagnosis of SSI of dermatosurgical wounds.ME

Biomass, community structure and phosphorus uptake of ectomycorrhizal fungi in response to phosphorus limitation and nitrogen deposition

Popular science summaryMycorrhizal associations Mycorrhizal fungi are organisms that live in association with plant roots and provide plants with water and nutrients in exchange for the sugars obtained during photosynthesis. In forested ecosystems mycorrhizal fungi are crucial for tree nutrition and trees rely heavily on these associations to take up key elements like nitrogen and phosphorus. As rHigh levels of nitrogen (N) deposition might result in a transition from N to phosphorus (P) limitation in high latitude forests. Thiscould have fundamental consequences for forest production, nutrient acquisition and nutrient leaching.I studied a Norway spruce forest in a region of high N deposition in southwest Sweden and added N, P or N+P to force thesystem to N or P limitation. I studied tree

Local initiatives and global regimes - Multi-scalar transition dynamics in the chemical industry

The breaking with regime logics is one of the key leverage points to enable a socio-technical transition. Understanding how, and under what conditions, this may happen is thus an important task for transition studies. Recent research on socio-technical regimes has shown that they may be less geographically bound than previously assumed. Regimes may instead be replicated and reinforced globally thr

What Does Your Corporate Brand Stand For?

Companies are extremely good at defining their product brands. Customers, employees, and other stakeholders know exactly what an iPhone is and means. But organizations are often less sure-footed when it comes to the corporate brand. What does the parent company’s name really stand for, and how is it perceived and leveraged in the marketplace and within the company itself?A clear, unified corporate

On the Limit Theory of Mixed to Unity VARs: Panel Setting With Weakly Dependent Errors

In this paper we re-visit a recent theoretical idea introduced by Phillips and Lee (2015). They examine an empirically relevant situation when multiple time series under consideration exhibit different degrees of non-stationarity. By bridging the asymptotic theory of the local to unity and mildly explosive processes, they construct a Wald test for the commonality of the long-run behavior of two se

The Impact of Grade Inflation on Higher Education Enrolment and Earnings

Although grade inflation is unfair and may imply inefficient allocation of human resources, current knowledge of grade inflation effects on individual outcomes is scarce. One explanation is probably the challenge of measuring and estimating causal grade inflation effects. This study examines the consequences of grade inflation at the upper secondary education level on enrolment in higher education
