OBJECTIVE: To compare the reliability of quantitative measurement of minimum hip joint space with a qualitative global assessment of radiological features for estimating the prevalence of primary osteoarthritis (OA) of the hip in colon radiographs.METHODS: All colon radiographs from patients aged 35 or older, taken at three different radiographic departments in Iceland during the years 1990-96, we

Purpose: To estimate inter-observer agreement with regard to describing adnexal masses using the International Ovarian Tumor Analysis (IOTA) terminology and the risk of malignancy calculated using IOTA logistic regression models LR1 and LR2, and to elucidate what explained the largest inter-observer differences in calculated risk of malignancy. Experimental Design: 117 women with adnexal masses we

In the past two decades, the eddy covariance technique has been used for an increasing number of methane flux studies at an ecosystem scale. Previously, most of these studies used a closed path setup with a tunable diode laser spectrometer (TDL). Although this method worked well, the TDL has to be calibrated regularly and cooled with liquid nitrogen or a cryogenic system, which limits its use in r

In this paper, a parametric analysis on the main engine calibration parameters applied on gasoline Partially Premixed Combustion (PPC) is performed. Theoretically, the PPC concept permits to improve both the engine efficiencies and the NOx-soot trade-off simultaneously compared to the conventional diesel combustion. This work is based on the design of experiments (DoE), statistical approach, and i

Tunnel Field Effect Transistor (TFET), based on band-to-band tunneling, overcomes the thermal limit (subthreshold slope (S) > 60 mV/decade) of the MOSFETs by filtering the high-energy Fermi tail, thereby allowing a substantial reduction of supply voltage and power consumption. Despite the steep slope behavior, TFETs can suffer from ambipolarity wherein carriers tunnel into the channel at both high

Background and purpose — Total hip arthroplasty (THA) is increasing as treatment of displaced femoral neck fractures. Several studies compare hemiarthroplasty (HA) with THA, but results vary and few studies report on medical complications. We examined the outcome of THA and HA with a focus on medical complications, hip complications, and death. Patients and methods — Data from the Swedish Hip Arth

Algorithms for secure encryption in a post-quantum world are currently receiving a lot of attention in the research community. One of the most promising such algorithms is the code-based scheme called QC-MDPC, which has excellent performance and a small public key size. In this work we present a very efficient key recovery attack on the QC-MDPC scheme using the fact that decryption uses an iterati

Objective: To estimate the genetic contribution to traumatic and degenerative meniscus tears for men and women across the lifespan. Methods: We linked the Swedish Twin Register with individual-level national healthcare data to form a 30-year, population-wide, longitudinal twin cohort. To study genetic contribution to meniscus tears, we estimated the heritability and familial risk using incident tr

INTRODUCTION: Despite much literature on reference values of acid-base status in umbilical cord blood at birth, there are as yet no studies performed to determine gestational age-dependent references in cord venous blood and no studies on preterm acid-base standards. Similarly, the normal reference range of Apgar scores for term and preterm infants has not yet been determined.MATERIAL AND METHODS:

Background: Isocapnic hyperventilation (IHV) is a method that shortens time to extubation after inhalation anaesthesia using hyperventilation (HV) without lowering airway CO 2 . In a clinical trial on patients undergoing long-duration sevoflurane anaesthesia for major ear–nose–throat (ENT) surgery, we evaluated th

This report represents the main findings from the first round of village-level community assessment of the economic and social impacts monitoring of COVID-19 in Myanmar. A total of 224 individuals (four per village, selected for their knowledge of the situation of the village, and representativity of key sub-groups), were interviewed across 56 villages, in two townships in every state and region a

Background: Popliteal artery aneurysm (PAA) carries a risk of sudden thromboembolism, resulting in acute limb ischemia (ALI). Since 2010, all 65 year-old-men in Region Skåne are invited for abdominal aortic aneurysm (AAA) screening, and subsequently for PAA if AAA is detected. The aims of the study were to explore if the ratio of PAAs treated electively compared with acute has changed since the im

BACKGROUND: Transforming growth factor-β1 (TGF-β1) is a potent regulator of cell growth and differentiation. TGF-β1 has been shown to be a key player in tissue remodeling processes in a number of disease states by inducing expression of extracellular matrix proteins. In this study a quantitative proteomic analysis was undertaken to investigate if TGF-β1 contributes to tissue remodeling by mediatin

Restenosis is a major problem after balloon angioplasty and stent implantation. The aim of this study is to introduce gadolinium neutron capture brachytherapy (GdNCB) as a suitable modality for treatment of stenosis. The utility of GdNCB in intravascular brachytherapy (IVBT) of stent stenosis is investigated by using the GEANT4 and MCNP4B Monte Carlo radiation transport codes. To study capture rat

Studies seeking to validate real-time three-dimensional echocardiography (3DE) with regard to cardiac function and dimensions have almost exclusively used apical views. However, it has never been examined whether apical views are preferable to parasternal or subcostal views. In the present study, we compared the feasibility of 3DE volumetric measurements of the four heart chambers in three differe

Background: Clinical studies have evaluated a correlation between preoperative walking capacity or function and outcome after hip and knee joint replacement surgery with contradictory results. Our aim was to investigate the effect of preoperative metabolic and/or aerobic exercise on surgical outcome, as well as to evaluate the effect of cumulated exercise by using a cutoff value at 3.5 hours throu

Double emulsions have a great potential in food applications, such as low calorie products and to improve sensory properties. For the dairy industry, double emulsions could be used to produce a product with a lower fat content which maintain the same properties as regular whipping cream. The purpose of this project was to obtain a stable Water-in-Oil (W/O) emulsion with butter oil with a small mea
