BACKGROUND: Internal hernias occur frequently after laparoscopic gastric bypass. We have found no data on the relative strength of the various techniques available for closing these defects. The present study was performed to obtain such data to form a theoretical basis for clinical studies. METHODS: Six piglets were operated laparoscopically and four loops of small bowel created in each. These me
Background and aims: The effects of central sleep apnea in Cheyne-Stokes respiration on sleep-related symptoms and quality of life are not very well established. We aimed to investigate whether Cheyne-Stokes respiration is related to health-related quality of life. We also studied the impact on daytime sleepiness and nocturnal dyspnea. Methods: Included were 203 consecutive patients, stabilized fo
Popular Abstract in Swedish Kroniska ländryggsbesvär är en ekonomisk belastning för sjukvården och samhället i stort, och ger framför allt ett personligt lidande för den drabbade. Nästan alla (75-80 %) kommer att ha åtminstone en episod med ryggbesvär någon gång under sin livstid. Hälften av dessa kommer att ha utstrålande bensmärtor och ofta är besvären ett symtom på ischias (nervrotspåverkan). MRadicular pain is in the majority of cases caused by a disc herniation with a coexisting inflammation. It is characterized by positive neural tension tests, such as the Slump test, and by decreased range of motion (ROM) in the straight leg raising test (SLR) and lumbar flexion (Fingertip-to-floor test[FTF]). This may suggest that improvement in ROM correlates to reduction of self-reported disabili
This article examines how knowledge of an impending collapse of modern industrial civilization circulated in Swedish society during the early 1970s. The point of departure is the Swedish biochemist Gösta Ehrensvärd’s (1910–1980) short book Före – efter: En diagnos (Before – After: A Diagnosis). In this book Ehrensvärd argued that the technologically advanced societies of the early 1970s would soon
Background: Hyper- as well as hypoglycemia may be detrimental for brain energy metabolism and even a moderate increase in blood glucose concentration can affect outcome adversely. During physiological conditions, glucose concentration obtained from microdialysis of subcutaneous adipose tissue adequately reflects plasma glucose concentration. This study examines whether this correlation is also obt
Background and Purpose: Leptin, an important hormone for body weight regulation, may be involved in the pathogenesis of cardiovascular manifestations of obesity. We tested whether leptin may be an independent risk marker for stroke in a case-referent study. Methods: Definitive acute stroke events, defined by MONICA criteria, were identified from October 1, 1995 to April 30, 1999. Referents without
Objective: To compare the efficacy of adalimumab, etanercept, and infliximab in patients with established rheumatoid arthritis (RA) taking concomitant methotrexate (MTX) by calculating the number needed to treat (NNT) using three different methods. Methods: A systematic literature search of the Cochrane Library, MEDLINE, and EMBASE was conducted from inception to 30 June 2006. Two pairs of investi
A new sensing technology platform integrating magnetic permeability detection and a two-site heterogeneous immunoassay in a one-step analysis is described. As a platform model, measurements of C-reactive protein (CRP), a cardiac and inflammation marker, were performed in a rapid (11.5 min) high-sensitivity (hs) procedure with a low detection limit (0.2 mg/L) and accuracy (CV = 11%). The two-site h
The European Union has initiated a number of initiatives to improve resource efficiency in Europe. The Ecodesign Directive is one of the policy instruments that could aid the transition towards a more resource efficient economy. This paper examines the potential benefits and disadvantages in applying the Directive for this purpose, and reflects on the potential to apply certain types of standards.
The severe fouling common in food processing puts high demands on equipment cleaning. Adsorption of the protein betalactoglobulin to solid surfaces and its subsequent removal were followed using in situ ellipsometry. Most experiments were done in a stirred cuvette. Additionally, a flow cell was designed, which was employed in some work. The characteristics of the surface were shown to influence p
In this work, we present a ridged, microfabricated, force sensor that can be used to investigate mechanical interactions between cells exhibiting contact guidance and the underlying cell culture substrate, and a proof-of-function evaluation of the force sensor performance. The substrates contain arrays of vertical pillars between solid ridges that were microfabricated in silicon wafers using photo
The incorporation of drugs into Gelucires has been reported to increase the dissolution rate of poorly soluble drugs, often leading to improved drug bioavailability. In pharmaceutical applications, it is important to know how the excipient interacts with the drug, and how the mixture behaves during manufacturing, storage as well as during administration. The uptake of water by an amphiphilic excip
The present contribution discusses features of North Swedish intonational phonology. One characteristic feature is final element stress in compounds occurring particularly in dialects of North Botnia. The idea proposed here is that the accentual pattern (HL) of a compound has a different alignment in these dialects compared to East Standard Swedish. Another characteristic feature is related to a s
BACKGROUND: Mortality caused by acute pancreatitis in patients admitted to the hospital has been thoroughly investigated, but knowledge regarding outpatient fatalities is far from complete. The purpose of this study was to assess the incidence and clinical characteristics of patients who have died due to acute pancreatitis occurring outside the hospital. METHODS: Deaths caused by acute pancreatiti
Biodegradation is becoming an attractive mode of operation for eliminating toxic chemicals released from industrial processes or already present in the environment. One needs, however, not only to identify organisms capable of degrading such chemicals, but also to address the issue of whether these chemicals, after being degraded, will be toxic to the degrading organisms if present in high concent
Risk management is an important process and risk identification is an important part of this process, especially in development of medical software. This paper presents an experiment where physicians, developers and software developers for medical devices are asked to identify risk in a given scenario describing the procurement of a patient monitoring system. It is concluded that multiple roles an
Background: The acid-producing part of the rat stomach (fundus) is rich in endocrine cells, i.e. ECL cells and A-like cells. The ECL cells operate under gastrin control and manufacture histamine, the chromogranin-derived peptide pancreastatin and an unidentified peptide hormone. The A-like cells produce ghrelin, a newly discovered growth hormone-releasing hormone. Surgical removal of the entire gl
The impact of the quantization of SNR measurements on the throughput of a multiuser diversity scheme for constant-rate transmission is investigated under a block-Rayleigh fading assumption. In the downlink, each user measures its SNR, quantizes it, and feeds it back to the transmitter, which transmits a packet to the user with the highest quantized SNR. In the case of several users having the same
