Objectives: to characterize the clinical presentation of patients with acute thrombo-embolic occlusion of the superior mesenteric artery (SMA).Design: prospective study.Materials: twenty-four consecutive patients admitted to Blekinge County Hospital, Karlskrona, Sweden, with acute thrombo-embolic occlusion of the SMA, over a three-year period from April 1999 through March 2002.Methods: clinical da

Background: Abdominal aortic aneurysm (AAA) and cardiovascular disease are intimately associated, the latter representing the most common cause of death in Sweden. Cardiac complications are held responsible for the majority of perioperative morbidity and mortality in patients undergoing repair of AAA. The importance of preoperative thorough cardiac assessment is therefore obvious. The aim of this

Objectives: Open abdomen (OA) treatment is sometimes necessary after surgery for aortic aneurysm (AA), to prevent or treat abdominal compartment syndrome (ACS). A multicentre study evaluating vacuum-assisted wound closure (100-150 mmHg) and mesh-mediated fascial traction (VAWCM) was performed. Methods: All patients treated with OA after AA repair (2006-2009) were prospectively registered at four c

The purpose of this study is to investigate possible differences in brain structure, as measured by T1-weighted MRI, between patients with systemic lupus erythematosus (SLE) and healthy controls (HC), and whether any observed differences were in turn more severe in SLE patients with neuropsychiatric manifestations (NPSLE) than those without (non-NPSLE). Structural T1weighted MRI was performed on 6

Worldwide, 463 million people are affected by diabetes of which the majority is diagnosed with Type 2 Diabetes (T2D). T2D can ultimately lead to retinopathy, nephropathy, nerve damage, and amputation of the lower extremities. α-Glucosidase, responsible for converting starch to monosaccharides, is a key therapeutic target for the management of T2D. However, due to substantial side effects of curren

Food texture affects palatability. A new study finds that the common dew fly Drosophila melanogaster is also choosy when it comes to food texture. Flies evaluate size and presence of food particles through neurons in the tongue that express the mechanically activated channel protein TMEM63.

Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To determine the effects of different regimens of systemic opioid analgesics in neonates (term or preterm) undergoing surgery, on mortality, pain and major neurodevelopmental disability. These different regimens may include: different doses of the same opioid; different routes of administration of

Randomised controlled trials conducted using cohorts and routinely collected data, including registries, electronic health records and administrative databases, are increasingly used in healthcare intervention research. A Consolidated Standards of Reporting Trials (CONSORT) statement extension for trials conducted using cohorts and routinely collected data (CONSORT-ROUTINE) has been developed with

This thesis proposes approaches and models to increase the energy saving of the User Equipment (UE) in Long-Term Evolution (LTE) and 5G. The focus is mainly on Discontinuous Reception (DRX), the UE energy saving mechanism that was first introduced in LTE and will play an important role in 5G too.In this thesis, we take two main approaches. The first approach is based on joint optimization of DRX a

The Learning with Errors (LWE) problem receives much attention in cryptography, mainly due to its fundamental significance in post-quantum cryptography. Among its solving algorithms, the Blum-Kalai-Wasserman (BKW) algorithm, originally proposed for solving the Learning Parity with Noise (LPN) problem, performs well, especially for certain parameter settings with cryptographic importance. The BKW a

The focus of this study was the empirical modelling of the high-speed bearings life and failure modes of a through-flow universal motor. An approach was used facilitating predictions of the life through-range of various conditions. The model estimates bearing life for the survival probability of 50% – L50. It influences parameters such as bearing temperature, speed factor, equivalent load, grease

Air pollution causes premature mortality and morbidity globally, but these adverse health effects occur over proportionately in low-and middle-income countries. Lack of both air pollution data and knowledge of its spatial distribution in African countries have been suggested to lead to an underestimation of health effects from air pollution. This study aims to measure nitrogen oxides (NOx), as wel

Background: Previous studies suggested that automated peritoneal dialysis (APD) could be improved in terms of shorter treatment times and lower glucose absorption using bimodal treatment regimens, having ‘ultrafiltration (UF) cycles’ using a high glucose concentration and ‘clearance cycles’ using low or no glucose. The purpose of this study is to explore such regimes further using mathematical opt

Background: Little is known about the heterogeneous etiology of suspected non-Alzheimer’s pathophysiology (SNAP), a group of subjects with neurodegeneration in the absence of β-amyloid. Using antemortem MRI and pathological data, we investigated the etiology of SNAP and the association of neurodegenerative pathologies with structural medial temporal lobe (MTL) measures in β-amyloid-negative subjec

Wood is a renewable resource and a promising construction material for the growing bio-based economy. Efficiently utilising wood in the built environment requires a comprehensive understanding of the dynamics regarding its usability. Durability is an essential property to consider, as various types of exposure create conditions for the deterioration of wood through biotic and abiotic agents. Biode
