Background. The incidence and severity of invasive group A streptococcal infection demonstrate great variability over time, which at least, in part, seems to be related to group A streptococcal type distribution among the human population. Methods. An enhanced surveillance study of invasive group A streptococcal infection (746 isolates) was performed in Sweden from April 2002 through December 200
Objectives: To assess correlations between Kellgren & Lawrence (KL) gradings, minimum joint space width (mJSW) measurements and the Boston Leeds Osteoarthritis Knee Score (BLOKS) within a cohort of obese patients with knee osteoarthritis (KOA). Methods: 192 Participants were recruited from an outpatient clinic (ClinicalTrials.gov: NCT00655941). Inclusion criteria were age >= 50 years, body mas
ObjectiveThe focus of this study was on the impact of spousal loss on the development of chronic pain thereafter. More specifically, the aim was to investigate the effect of experiencing low preparedness before a wife's death and the widower's chronic pain 4-5 years after loss. MethodsIn a population-based study in the years 2004-2005, anonymous questionnaires were sent out to 907 men in Sweden wh
Subject Objective: To assess the accuracy of a portable monitoring device based on peripheral arterial tonometry to diagnose obstructive sleep apnea (OSA). To propose a new standard for limited-channel device validation using synchronized polysomnography (PSG) home recordings and a population-based cohort. Design: Single-night, unattended PSG and Watch_PAT 100 (WP_100). Setting: Home environment.
An imbalance of the trace element status in human tissues and body fluids has been suggested as a contributing factor for the development of fibromyalgia (FM). The study comprised 38 females with defined fibrornyalgia (FM) according to generally accepted criteria from the American College of Rheumatology (ACR). They were compared with 41 females matched for age and Geographic location. The concent
STUDY OBJECTIVE: Studies have indicated that women are more vulnerable to the effect of tobacco smoking compared with men. The aim of this study was to explore the prevalence of reported respiratory symptoms and diseases according to smoking burden, age and sex. DESIGN: Questionnaire in a cross sectional population based study. SETTING: The BONT (Bronchial obstruction in Nord-Trondelag) study is p
An air sampling method for the determination of isocyanates. aminoisocyanates and amines formed during the thermal degradation Of polyurethane (PUR) is presented. The method is based on the collection of air samples using impinger flasks containing di-n-butylamine (DBA) in toluene with a glass fibre filter in series. Isocyanates are derivatized with DBA to urea derivatives, and amines are derivati
An indoor mating disruption experiment was performed on the stored-product pest Plodia interpunctella. The female of this: species emits a four-component pheromone blend consisting of Z9,E12-14: OAc, Z9,E12-14: OR Z9,E12-14: Ald, and Z9-14: OAc. Mating of Plodia interpunctella was disrupted up to 93% by using synthetic pheromone in small-scale plot experiments. The study was performed in 2.5 m x 2
In areas where tectonics and weathering have hydrogeological significance, electrical methods can assist in mapping the subsurface. In this work, resistivity imaging was used to map fractures, faults and quartz veins emplaced in strongly weathered volcanic rocks. The aim was to map geological units related to the formation of groundwater systems in the Rio Artiguas basin, Nicaragua. Eight 2D resis
PURPOSE: To assess how patients perceive health-related quality of life (HRQOL) after endovascular and open abdominal aortic aneurysm (AAA) repair. METHODS: Forty-two consecutive patients (33 men; mean age 74 years, range 46-81) were assessed prospectively before and after elective endovascular (n = 21) and open (n = 21) AAA repair. Aneurysm morphology dictated the type of repair. The two patient
Anesthetized, paralyzed and mechanically ventilated pigs were hypoventilated to extreme hypercapnia (PaCO2 approximately 20 kPa) at FiO2 0.5, and allotted to receive hypothermia (approximately 31.5 degrees C) and buffer infusion, (HB-group, n = 6) or to a hypothermic control group (H-group, n = 6). The HB-group had higher arterial pH (7.34 vs 7.09, P < 0.01) and plasma bicarbonate (58.8 vs 35.4 mm
Aims: To explore the incidence, severity, time course, and risk factors of clinically significant hyponatremia in desmopressin treatment for nocturia. Methods: Data from three multi-center phase 111 trials were pooled. Hyponatremia was categorised as borderline (134-130 mmol/L) or significant (<130 mmol/L). Risk factors were explored with logistic regression and subgroup analysis performed to expl
Magnetic compass orientation in birds has been shown to be light dependent. Results from behavioural studies indicate that magnetoreception capabilities are disrupted under light of peak wavelengths longer than 565 nm, and shifts in orientation have been observed at higher light intensities (43-44x1015 quanta s-1 m-2). To investigate further the function of the avian magnetic compass with respect
Objectives: The strategies used to support smoking cessation among quitters were investigated according to year of smoking cessation and sociodemographic characteristics. Methods: The 2004 public health survey in Skane, Sweden, is a cross-sectional study. A total of 27 757 people aged 18-80 answered a postal questionnaire. The participation rate was 59%. Different strategies to support smoking ces
Copolymers of N-acryloyl-m-aminophenylboronic acid (NAAPBA) with acryamide (AA), N,N-dimethylacrylamide (DMAA), and N-isopropylacrylamide (NIPAM) were found to adsorb on cross-linked agarose gel (Sepharose CL-6B) in the pH range from 7.5-9.2, due to specific boronate-sugar interactions. The molar percentages of phenylboronic acid (PBA) groups in the boronate-containing copolymers (BCCs), as estima
Hypoglycaemia is presumed to be the cause of death in about 3% of insulin-treated diabetic patients. Some of these patients suffer from hypoglycaemic brain damage, but the majority have no evident brain damage and are supposed to have died from other causes such as a cardiac arrhythmia. The putative mechanism is a hypoglycaemia-induced prolongation of the QT interval which increases the risk of ma
Determination of dissolved L-lactate in tomato paste and baby food samples using a SIRE-based (sensors based on injection of the recognition element) biosensor is reported. The measuring principle is based on the use of a small amount of enzyme, which is injected into an internal delivery flow system and held in direct spatial contact with the amperometric transducer by the use of a semipermeable
