Background: Echocardiography involves strenuous postures of the upper limbs. This study explored the physical workload in the neck and upper limbs in sonographers performing echocardiography, and the extent to which the workload differs from than in other work tasks (other sonographic examinations, and nonsonographic tasks). Methods: The physical load was assessed by inclinometry, goniometry, and

Gasoline partially premixed combustion (PPC) has shown potential in terms of high efficiency with low emissions of oxides of nitrogen (NOx) and soot. Despite these benefits, emissions of unburned hydrocarbons (UHC) and carbon monoxide (CO) are the main shortcomings of the concept. These are caused, among other things, by overlean zones near the injector tip and injector dribble. Previous diesel lo

Type of Study: This is a longitudinal, case-control clinical trial. Objectives: This study aims to track recovery time following a vocal loading task (VLT) imposing vocal fatigue and to explore if patients with functional dysphonia (FD) are worse affected by vocal loading, and if these patients take longer than others to recover. Methods: Fifty (n = 50) female participants in four vocal subgroups

Lactones, cyclic esters of hydroxycarboxylic acids, are interesting biofuel candidates as they can be made from cellulosic biomass and have favorable physical and chemical properties for distribution and use. The reactions of γ-valerolactone (GVL), γ-crotonolactone (2(5H)-F), and α-methyl-γ-crotonolactone (3M-2(5H)-F) with Cl, OD, and O3 were investigated in a static chamber at 700 Torr and 298 ±

BACKGROUND AND OBJECTIVES: To study selective regional binding for tau pathology in vivo, using PET with [(11) C]PBB3 in PSP patients, and other conditions not typically associated with tauopathy.METHODS: Dynamic PET scans were obtained for 70 minutes after the bolus injection of [(11) C]PBB3 in 5 PSP subjects, 1 subject with DCTN1 mutation and PSP phenotype, 3 asymptomatic SNCA duplication carrie

Background. Polypharmacy is known to increase the risk for drug-related problems, and some drugs, potentially inappropriate medications (PIMs), are especially troublesome. Objective. To analyse the effects on prescription of PIMs of the SäKLäK project, an intervention model created to improve medication safety for elderly patients in primary care. Method. The SäkläK project was a multiprofessional

Dramatic alterations in mechanical properties have been documented for osteoarthritic (OA) cartilage. However, the matrix composition underlying these changes has not been mapped and their aetiology is not entirely understood. We hypothesised that an understanding of the cartilage matrix heterogeneity could provide insights into the origin of these OA-related alterations. We generated serial trans

BACKGROUND/AIMS: Mobility disability (MD) and obesity are conditions which have been associated with weaker labour market attachment. This study investigates whether the combined burden of MD and obesity increase the risk of disability pension compared with having only one of these conditions (the reference group).METHODS: A nationwide cohort study, based on national surveys made between 1996 and

Diabetic foot ulcer is a serious complication in patients with diabetes. In most outcome studies of this condition, there is a combination of various types of ulcer and ulcer locations. Plantar ulcers are usually localized to the forefoot, and constitute a quarter of all diabetic foot ulcers. There are a limited number of studies regarding development of new ulcers following healing of a plantar f

BACKGROUND: In patients with sinus rhythm and normal atrioventricular conduction, pacing only the left ventricle with appropriate atrioventricular delays can result in superior left ventricular and right ventricular function compared with standard biventricular (BiV) pacing.OBJECTIVE: To evaluate a novel adaptive cardiac resynchronization therapy ((aCRT) algorithm for CRT pacing that provides auto

Objective: The purpose of this study was to compare postoperative rehabilitation with structured physiotherapy to the standard approach in patients with cervical radiculopathy (CR) in a prospective randomized study at 6 months follow-up based on measures of neck-related physical function, self-efficacy, and coping strategies. Methods: Patients with persistent CR and scheduled for surgery (N = 202)

The gut microbiomes of birds and other animals are increasingly being studied in ecological and evolutionary contexts. Numerous studies on birds and reptiles have made inferences about gut microbiota using cloacal sampling; however, it is not known whether the bacterial community of the cloaca provides an accurate representation of the gut microbiome. We examined the accuracy with which cloacal sw

Background: The effectiveness of different procedures in routine surgical practice for hernia repair with respect to chronic postoperative pain and reoperation rates is not clear. Methods: This was prospective cohort study based on a unique combination of patient-reported outcomes and national registry data. Virtually all patients with a groin hernia repair in Sweden between September 2012 and Apr

Background: Reliable and easy to administer screening instruments focusing on neurodevelopmental disorders and associated conditions are scarce. The Autism-Tics, AD/HD and other Comorbidities inventory (A-TAC) has previously been validated and reporting good- excellent validity for several disorders. This article aims to expand these findings by including more conditions in a substantially larger

Introduction: The aim of this study was to investigate school contextual effects on daily tobacco smoking, heavy alcohol use and hashish use among adolescents, using multilevel analyses adjusting for individual-level factors. Methods: The 2012 public health survey among adolescents in Skåne includes pupils in ninth grade in primary school (predominantly 15-16. years old) and second grade in second

Introduction: The central question this study sought to answer was whether the team members of Strategic Crisis Teams (SCTs) participating in mass-casualty incident (MCI) exercises in the Netherlands learn from their participation. Methods: Evaluation reports of exercises that took place at two different times were collected and analyzed against a theoretical model with several dimensions, looking

Tannerella forsythia is a poorly studied pathogen despite being one of the main causes of periodontitis, which is an inflammatory disease of the supporting structures of the teeth. We found that despite being recognized by all complement pathways, T. forsythia is resistant to killing by human complement, which is present at up to 70% of serum concentration in gingival crevicular fluid. Incubation

Background: The aim of this study was to develop and psychometrically test a short, patient-reported questionnaire to be used in clinical practice for patients with Irritable Bowel Syndrome (IBS). The Visual Analogue Scale for Irritable Bowel Syndrome (VAS-IBS) questionnaire was designed to measure the treatment response of symptoms and well-being in patients suffering from IBS. Methods: The VAS-I
