Inter-observer variation in target delineation and dose trade-off for radiotherapy of paediatric ependymoma

Postoperative radiotherapy for intracranial paediatric ependymoma is challenging both for target definition and treatment planning [1]. Delineation of the tumour bed is difficult, as structures in prior contact with the tumour will shift back into their original positions after surgery. In infratentorial cases, the target is adjacent to the brainstem and upper spinal cord, therefore the relatively

Risk of venous and arterial thromboembolism in patients with giant cell arteritis and/or polymyalgia rheumatica : A Veterans Health Administration population-based study in the United States

Background: Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are systemic inflammatory diseases that primarily affect elderly women. Objectives: To compare the risk of thromboembolic events and retinal vascular occlusions in GCA and/or PMR with that in osteoarthritis (OA), evaluating a veteran-based population. Methods: A total of 1535 patients with GCA, 10,265 with PMR, and 1203 with o

Structure of a model dye/titania interface : Geometry of benzoate on rutile-TiO2 (110)(1 × 1)

Scanned-energy mode photoelectron diffraction (PhD) and ab initio density functional theory calculations have been employed to investigate the adsorption geometry of benzoate ([C6H5COO]-) on rutile-TiO2(110)(1 × 1). PhD data indicate that the benzoate moiety binds to the surface through both of its oxygen atoms to two adjacent fivefold surface titanium atoms in an essentially upright geometry. Mor

Prediagnostic alterations in circulating bile acid profiles in the development of hepatocellular carcinoma

Bile acids (BAs) play different roles in cancer development. Some are carcinogenic and BA signaling is also involved in various metabolic, inflammatory and immune-related processes. The liver is the primary site of BA synthesis. Liver dysfunction and microbiome compositional changes, such as during hepatocellular carcinoma (HCC) development, may modulate BA metabolism increasing concentration of c

Atrial fibrillatory rate as predictor of recurrence of atrial fibrillation in horses treated medically or with electrical cardioversion

Background: The recurrence rate of atrial fibrillation (AF) in horses after cardioversion to sinus rhythm (SR) is relatively high. Atrial fibrillatory rate (AFR) derived from surface ECG is considered a biomarker for electrical remodelling and could potentially be used for the prediction of successful AF cardioversion and AF recurrence. Objectives: Evaluate if AFR was associated with successful tr

Cognitive performance, fatigue, emotional and physiological strains in simulated long-duration flight missions

Pilots in long-duration flight missions in single-seat aircraft may be affected by fatigue. This study determined associations between cognitive performance, emotions and physiological activation and deactivation–measured by heart rate variability (HRV)–in a simulated 11-h flight mission in the 39 Gripen aircraft. Twelve participants volunteered for the study. Perceived fatigue was measured by the

SmartFlareTM is a reliable method for assessing mRNA expression in single neural stem cells

BACKGROUND One of the most challenging tasks of modern biology concerns the real-time tracking and quantification of mRNA expression in living cells. On this matter, a novel platform called SmartFlareTM has taken advantage of fluorophore-linked nanoconstructs for targeting RNA transcripts. Although fluorescence emission does not account for the spatial mRNA distribution, NanoFlare technology has g

Penetration Depth and Coherence Length in the Superconductor β-PdBi2

Small angle neutron scattering experiments have been carried out in the mixed state to determine the values and anisotropy of the penetration depth and coherence length in the superconductor β-PdBi2. The distortion of the vortex lattice observed on changing the magnetic field direction suggests that the a–c anisotropy of penetration depth in β-PdBi2 is small. With the magnetic field applied along

In a Land of Dreams : Left-Wing Politics and the Place of the Holocaust in Tage Erlander´s Sweden

As a consequence of Sweden’s status as a non-belligerent country during World War II and the continuous growth of its welfare state thereafter, the concept of a “People’s Home” and a “provisional Utopia,” a social support system characterized by equality and material prosperity, were central aspects of the country’s postwar policy. This article focuses on the ideological and political stance of th

Results-Based Financing for Health : A Case Study of Knowledge and Perceptions Among Stakeholders in a Donor-Funded Program in Zambia

In 2015, the Zambian government and the Swedish International Development Cooperation Agency (Sida) signed an agreement in which Sida committed to funding a program for Reproductive, Maternal, Newborn, Child, Adolescent Health and Nutrition (RMNCAH). The program includes a results-based financing (RBF) model that aims to reward Zambian districts for improved district-wide results on relevant indic

Understanding client satisfaction in elderly care: new insights from social resource theory

Social resource theory suggests that social interaction can be conceived as resource transaction or exchange with behaviours falling within six fundamental resource categories (i.e. love, status, information, money, goods, and services) organised along two underlying dimensions: particularism–universalism and concreteness–abstractness. With the purpose of extending knowledge about quality of care,

Assessing person-centred care: An item response theory approach

Given recent advances in psychometric assessment, there is a need for assessment studies using modern test theory in the field of person-centred care, mainly due to the dominant use of analytical strategies based on classical test theory. The main objective of the present study was thus to examine whether selected items from commonly used instruments of person-centred care were able to differentia

The Development and Inclusion of Questions on Surgery in the 2018 Zambia Demographic and Health Survey

Background: While primary data on the unmet need for surgery in low- and middle-income countries is lacking, household surveys could provide an entry point to collect such data. We describe the first development and inclusion of questions on surgery in a nationally representative Demographic and Health Survey (DHS) in Zambia. Method: Questions regarding surgical conditions were developed through a
