France has undertaken the most ambitious reform of healthcare education in more than 10 years. It has resulted in a hybrid system with multiple pathways, granting admission into the healthcare professions after competitive exams. The reform continues the trend to increase the quotas limiting the number of second year healthcare students, and also creates new local access options to healthcare education.

At such resolutions, most existing software packages for diffeomorphic image registration are prohibitively expensive. As a result, practitioners first significantly downsample the original images and then register them using existing tools.

The present study aimed to elucidate dynamics of tree-level C sink activity and allocation of recent photoassimilates (C ) and stored C in c. 70-year-old Norway spruce (Picea abies) trees during a 4-week period after drought release.
View Article and Find Full Text PDFCarbon (C) exuded via roots is proposed to increase under drought and facilitate important ecosystem functions. However, it is unknown how exudate quantities relate to the total C budget of a drought-stressed tree, that is, how much of net-C assimilation is allocated to exudation at the tree level. We calculated the proportion of daily C assimilation allocated to root exudation during early summer by collecting root exudates from mature Fagus sylvatica and Picea abies exposed to experimental drought, and combining above- and belowground C fluxes with leaf, stem and fine-root surface area.

Many helminths suppress the immune system of their hosts to prolong their survival. This helminth-induced immunosuppression "spills over" to unrelated antigens and can suppress the immune response to vaccination against other pathogens.

The Covid-19 pandemic has recently drawn public attention towards hospital capacity and has added new urgency to discussions on the future role of hospitals. In this context, recent experience in Germany provides valuable information for health systems seeking to manage hospital capacity.

Context: Despite numerous examples of health policy transfer in Western health systems, the nature of such "inspired" reforms has received little detailed attention. The aim of this article is to apply and refine a specific theoretical angle for the analysis of these reforms using the theoretical frameworks of transfer and translation.
Methods: The design is based on a comparative case study: the introduction of disease management programs (DMPs) for diabetes in Germany in 2002 and in France in 2008, drawing on a literature review and semistructured interviews.
Helminths are large multicellular parasites that infect one quarter of the human population. To prolong their survival, helminths suppress the immune responses of their hosts. Strongyloides ratti delays its expulsion from the gut by induction of regulatory circuits in a mouse strain-specific manner: depletion of Foxp3 regulatory T cells (Treg) improves the anti-S.

Purpose: Pay-for-performance (P4P) as an innovation for improved health care has been introduced in many health systems worldwide. The aim of this article is to apply and refine a specific theoretical angle for the analysis of these reforms, the theoretical frameworks of public policy instruments and programmatic actors, in order to highlight differences between countries.
Design/methodology/approach: This analysis is based on a comparative case study of the introduction of P4P in France and Germany in the ambulatory sector for the period from 2007 until 2017.

We present a Gauss-Newton-Krylov solver for large deformation diffeomorphic image registration. We extend the publicly available CLAIRE library to multi-node multi-graphics processing unit (GPUs) systems and introduce novel algorithmic modifications that significantly improve performance. Our contributions comprise () a new preconditioner for the reduced-space Gauss-Newton Hessian system, () a highly-optimized multi-node multi-GPU implementation exploiting device direct communication for the main computational kernels (interpolation, high-order finite difference operators and Fast-Fourier-Transform), and () a comparison with state-of-the-art CPU and GPU implementations.

Introduction: Thyroid transcription factor 1 (TTF-1) is a prognostic biomarker in lung adenocarcinoma; however, TTF-1-positive patients also display more favorable factors like actionable target mutations. In contrast, TTF-1-negative cancer is a poorly described entity. We performed a retrospective study to characterize a TTF-1-negative phenotype and to evaluate outcome depending on the chemotherapy regimen applied in the EGFR/ALK-negative population.

As part of the Roamer project, we sought to have a picture of the available mental health research (MHR) funding, capacity-building and infrastructures resources and to establish consensus-based recommendations that would allow an increase of European MHR resources and enable better use and accessibility to them. The methods fell into three sections (i) a review of the literature, (ii) a mental health-related keywords search within the Cordis, On-Course and Meril databases which contain information on European research funding, training and infrastructures. These reviews provided an overview that was presented to (iii) two experts workshops with 28 participants drawn from academic which identified gaps and produced recommendations.

Basophils are innate effector cells that may also contribute to the initiation and amplification of adaptive immune responses. Here, we use constitutively basophil-deficient Mcpt8-Cre mice to analyze the impact of basophils during initiation and execution of the protective type 2 responses to both, a primary infection and a challenge infection of immune mice with the helminth parasite Strongyloides ratti.

The aim of this retrospective study was to evaluate and quantify the additional benefit of LAT in synchronous OMD and to further identify prognostic factors for survival.
Patients And Methods: A propensity score-matched pairs analysis was performed on a set of patient and disease variables in 180 patients, treated for synchronous single organ OMD including non small-cell and neuroendocrine lung cancer with ≤4 metastases between 2000 and 2016 in 3 lung cancer centers in Berlin, Germany.
Aims: Although many mental health care systems provide care interventions that are not related to direct health care, little is known about the interfaces between the latter and core health care. 'Core health care' refers to services whose explicit aim is direct clinical treatment which is usually provided by health professionals, i.e.

Accumulating evidence suggests that IL-9 acts via both, initiation and regulation of adaptive immune responses and direct activation of intestinal effector pathways. Here we use IL-9 receptor deficient mice on BALB/c and C57BL/6 genetic background to dissect effector and regulatory functions of IL-9 during infection with the parasitic nematode Strongyloides ratti.
