Duodenum edema due to reduced lymphatic drainage leads to increased inflammation in a porcine endotoxemic model.

BackgroundInterventions, such as mechanical ventilation with high positive end-expiratory pressure (PEEP), increase inflammation in abdominal organs. This effect could be due to reduced venous return and impaired splanchnic perfusion, or intestinal edema by reduced lymphatic drainage. However, it is not clear whether abdominal edema per se leads to increased intestinal inflammation when perfusion

Suction cup on a piston-based chest compression device improves coronary perfusion pressure and cerebral oxygenation during experimental cardiopulmonary resuscitation

Introduction: The presented study aimed to investigate whether a mechanical chest compression piston device with a suction cup assisting chest recoil could impact the hemodynamic status when compared to a bare piston during cardiopulmonary resuscitation.Methods: 16 piglets were anesthetized and randomized into 2 groups. After 3 minutes of induced ventricular fibrillation, a LUCAS 3 device was used

The use of Diffusion Weighted Imaging and Intravoxel Incoherent Motion to Assess Edema and Perfusion in Abdominal Organs during Endotoxemia.

Diffusion weighted magnetic resonance imaging (DW-MRI) technique probing the microscopic movement of water molecules in tissue, allows for the quantification of water diffusivity and the contribution of perfusion to the total amount of water. In the last decades, its use in organs other than the brain has increased and it has successfully been applied to abdominal organs; otherwise the use of DWI

Continuous chest compressions are associated with higher peak inspiratory pressures when compared to 30:2 in an experimental cardiac arrest model.

BackgroundVentilation during cardiopulmonary resuscitation (CPR) has long been a part of the standard treatment during cardiac arrests. Ventilation is usually given either during continuous chest compressions (CCC) or during a short pause after every 30 chest compressions (30:2). There is limited knowledge of how ventilation is delivered if it effects the hemodynamics and if it plays a role in the

Comparing survival and outcomes in isolated versus polytrauma-associated TBI: a retrospective cohort study.

BACKGROUND: One in four patients with moderate to severe traumatic brain injury (TBI) also has other body district injuries (OBD). The impact of OBD on mortality and disability is debated. This study compared outcomes of TBI patients with polytrauma (p-TBI) versus isolated TBI (alone-TBI) and identified outcome determinants, focusing on survival time and prognosis.METHODS: This single-center, retr

Transparent Reflexivity : How to Exude Neutrality and Navigate Gatekeeping Through Shifting Positionality?

Gaining access to interviewees when carrying out qualitative research is a time-consuming, challenging undertaking. When face to face with gatekeepers, the work of convincing them to share their contacts and knowledge is not over, particularly when the research involves antagonistic groups and the researcher’s positionality can be scrutinized in relation to that. In this article, based on my field

Feminist situated scholarship as the antidote to the necrolocution

Gibson asks: how do we undo the harms of this participatory turn? How can we acknowledge that the material never fully accounts for the immaterial? How do we avoid becoming ants that need to spatialize and make visible everything they research? In this piece, I argue that some of these issues can be mediated and mitigated by entering the field with a feminist epistemological stance. I provide thre

Disrupted place attachments and emotional energy geography in fracked Appalachia

To date, there has been limited analysis at the intersection of extractive industry and emotional geography. Our research addresses this intersection by investigating how gas extraction, production, and distribution have disrupted residents’ place attachment, and how this disruption is emotionally embodied. This research relies on 24 interviews and 2 workshops conducted in Ohio, Pennsylvania, and

Buxus sempervirens and Laurus nobilis leaves from an archaeological site at 7300 cal BP (La Draga, Spain) provide a better understanding of past vegetation and human activities

Leaves are valuable, but very rare, remains in archaeological contexts, as they can provide precise information on the landscape vegetation composition, the past climatic conditions and the use of plant resources in a settlement. La Draga (Spain) is an early Neolithic site partially waterlogged, which has allowed the preservation of organic material. During the excavation of the oldest level (7300

Making sense of EU migration cooperation with third countries as a distributive (in)justice question. Does money do the job?

The EU and its Member States have been increasingly engaging into cooperation with third countries with the view to containing movements and preventing refugees from entering European soil. These cooperative arrangements have been critiqued for allowing EU countries to evade their responsibilities vis-a-vis refugees subjecting them to substandard treatment in transit countries. From a distributive

The future of a past porous city : public spaces as integrated components of Lahijan's stormwater management infrastructure

The emergence of the modern urban water infrastructure, albeit facilitated the waste- and stormwater management, it left some negative imprints on Iran's urban and natural environment. Among which changing the hydrology of urban watershed has great importance. Moreover, lack of resilience of the current stormwater management infrastructure is increasing the risks of urban flooding and pollution of

A comprehensive study on dynamics of flames in a nanosecond pulsed discharge. Part I: Discharge formation and gas heating

Nanosecond pulsed discharges (NPD) have been extensively used in plasma-assisted combustion to stimulate combustion kinetics. Experimental measurement of the energy transfer processes in non-equilibrium plasma-assisted processes is extremely difficult, as the non-equilibrium plasma discharge involves numerous different species with transient and complex three-dimensional structures across various

A comprehensive study on dynamics of flames in a nanosecond pulsed discharge. Part II: Plasma-assisted ammonia and methane combustion

Understanding the flame dynamics in a nanosecond pulsed discharge (NPD) is imperative for the novel technology of plasma-assisted combustion. We conducted a systematic study on the dynamics of atmospheric NPD-assisted flames in single-pulse mode using Rayleigh scattering combined with structured illumination. The study is divided into two parts. Part I detailed the measurements and CH4/air flame r

Fluorescence lifetime imaging of nitric oxide in nanosecond pulsed discharge-assisted NH3/air flames

Laser-induced fluorescence (LIF) is a widely used non-invasive method for characterizing NOx emission, mostly in combustion applications, but also in many plasma facilities. Under the carbon-free prerequisite, non-thermal plasma-assisted combustion (PAC) is a promising technology to address the low flammability issues of ammonia (NH3) flames, but nitric oxide (NO) emission remains unknown. NO quan

Screening performance and characteristics of breast cancer detected in the Mammography Screening with Artificial Intelligence trial (MASAI) : a randomised, controlled, parallel-group, non-inferiority, single-blinded, screening accuracy study

Background: Emerging evidence suggests that artificial intelligence (AI) can increase cancer detection in mammography screening while reducing screen-reading workload, but further understanding of the clinical impact is needed. Methods: In this randomised, controlled, parallel-group, non-inferiority, single-blinded, screening-accuracy study, done within the Swedish national screening programme, wo
