1. 21. Effects of Negative Pressure Wound Therapy on Perivascular Groin Infections after Vascular Surgery. Wound Healing, Cost-Effectiveness and Patient-Reported Outcome

   Sammanfattning : Abstract Background: Surgical site infection (SSI) in the groin after vascular surgery is common and deep perivascular infection leads to long periods of hospitalization, sometimes to amputation and/or death. Negative pressure wound therapy (NPWT) is increasingly used for treating wounds such as deep perivascular groin infections after vascular surgery, but there is no scientific evidence supporting its benefit over traditional wound therapy.

3. 22. Formation of solar bipolar regions : Magnetic flux concentrations from suction of the negative effective magnetic pressure instability

   Författare :Illa Rivero Losada; Axel Brandenburg; Matthias Rempel; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetohydrodynamics MHD ; turbulence; dynamo; Sun: magnetic fields; Sun: rotation; Sun: activity; Sun: dynamo; Astronomy; astronomi;

   Sammanfattning : Sunspots stand out on the visible solar surface. They appear as dark structures evolving and changing over time. They host energetic and violent events, like coronal mass ejections and flares, and concentrate strong magnetic fields. LÄS MER

4. 23. Modelling of Diffuse Brain Injury: Combining Methods to Study Possible Links between Transient Intracranial Pressure and Injury

   Författare :Ulrika Krave; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; animal model; astrocytosis; diffuse axonal injury; neurofilaments; diffuse brain injury; rotational acceleration; closed head trauma; rabbit; finite element analysis; intracranial pressure; injury mechanisms;

   Sammanfattning : The objectives of this research are the study of sagittal rotational acceleration induced diffuse brain injury mechanisms. Such injuries are common in vehicle accidents in particular; the consequences range from mild to severe symptoms and may lead to persistent neurological dysfunction. LÄS MER

5. 24. Lung and chest wall properties during mechanical ventilation

   Författare :Per Erik Persson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical ventilation; Respiratory mechanics; Esophageal pressure; Positive end-expiratory pressure;

   Sammanfattning : Background: Mechanical ventilation causes injury to the lungs due to high pressures and high volumes. Pressure affecting the lungs, the transpulmonary pressure, needs to be monitored to minimise harmful side effects but then lung and chest wall mechanics need to be separately considered. LÄS MER
