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

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

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

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

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

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

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

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

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

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

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

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

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

Chamber measurements of trace gas fluxes between the land surface and the atmosphere have been conducted for almost a century. Different chamber techniques, including static and dynamic, have been used with varying degrees of success in estimating greenhouse gases (CO2, CH4, N2O) fluxes. However, all of these have certain disadvantages which have either prevented them from providing an adequate es

Historical wage studies have never been able to truly or accurately address the changes in the working year. Real wages have almost always been based on the wages of unskilled and casual laborers, typically paid by the day. Their annual incomes are not clear or obvious – the income is directly dependent on how many days they work. Implicitly the literature has assumed that the number of days worke

Purpose: This study investigates the relationship between sick-listed patients’ return to work (RTW) expectancy and how they perceive that their physicians evaluate their ability and volition for RTW.Methods: Hierarchical logistic regression controlling for sociodemographic factors and pain characteristics was carried out on cross-sectional data from 205 participants (mean age= 47.24±9.66 years, 8
