Aims To investigate self-reported cold sensitivity and functional disability after a repaired major nerve trunk injury in the upper extremity. Methods We identified 735 individuals with a major nerve trunk injury in the upper extremity, surgically treated with direct nerve repair or reconstructed with nerve autografts, in the Swedish national quality registry for hand surgery (HAKIR). Patient-repo

Patients with heart valve prosthesis (HVP) and Staphylococcus aureus bacteremia (SAB) are at risk for endocarditis. In this retrospective, population-based cohort study of 134 patients with SAB and HVP, 97 patients (72%) were diagnosed with possible endocarditis. Despite that most patients with possible endocarditis received short antibiotic treatment, only 3 patients suffered recurrent SAB.

Introduction: Cardiac resynchronization therapy (CRT) is an established treatment for heart failure in selected patients. However, current guideline indications do not accurately predict individual prognosis with CRT, and up to 30% are nonresponders. Previous studies have shown that QRS area reduction following CRT is associated with improved survival. This study evaluates the incremental value of

Aim: This randomised controlled trial evaluated changes in parental self-efficacy and children's weight, after a Child-Centred Health Dialogue about preventing obesity. Methods: We randomly assigned 37 Child Health Centres in Skåne county Sweden to provide usual care or the dialogue intervention. They included centres from high and low socioeconomic areas. The outcomes were changes in parental sel

Purpose: An elevated sense of vocal effort due to increased vocal demand is frequently reported by patients with voice disorders. However, effects of vocal warm-up on self-assessed vocal effort have not been thoroughly examined. A recently developed version of the Borg CR-10 Scale facilitates vocal effort assessments, following different vocal warm-up tasks. Methods: Effects of a short (5 min) voc

Herein, metal–organic chemical vapor deposition (MOCVD) of GaN layers doped with Mg atoms to the recognized optimum level of [Mg] ≈2 × 1019 cm−3 is performed. In a sequence of MOCVD runs, operational conditions, including temperature and flow rate of precursors, are maintained except for intentionally larger flows of hydrogen carrier gas fed into the reactor. By employing the largest hydrogen flow

A structured approach to derive the water activity function of cellulose-based materials which describe the sorption behavior from dry fiber up to the fiber saturation point is proposed. The coupling between the sorption isotherm and the net isosteric heat of sorption is incorporated in a consistent way, which allows for coupled heat-diffusion problems to be solved. Three different models are deri

BACKGROUND: User involvement in research has rapidly increased and is often a precondition to obtain research funding. Benefits such as effectiveness and increased relevance of research are described in the literature, but the evidence to support this is weak. Little is known about ageing and health researchers' experiences and perspectives towards user involvement in research, and their attitudes

Background: Early diagnosis and compression treatment are important to prevent progression in breast cancer-related arm lymphedema (BCRAL). However, some mild BCRAL can be reversible, and therefore, compression treatment may not be needed. The aim of this study was to investigate the proportion of women with mild BCRAL showing progression/no progression of lymphedema after treatment with or withou

Here, a new accurate approach is presented to quantify the degree of crystallinity of regenerated cellulose textile fibers using wide-angle X-ray scattering. The approach is based on the observation that the contributions to the scattering from crystalline and amorphous domains of the fibers can be separated due to their different degree of orientation with respect to the fiber direction. The meth

Background: In recent years, a lot of effort has been put in the enhancement of medical imaging using artificial intelligence. However, limited patient data in combination with the unavailability of a ground truth often pose a challenge to a systematic validation of such methodologies. The goal of this work was to investigate a recently proposed method for an artificial intelligence-based generati

The evidence-based medicine (EBM) movement is stepping up its efforts to assess medical artificial intelligence (AI) and data science studies. Since 2017, there has been a marked increase in the number of published systematic reviews that assess medical AI studies. Increasingly, data from observational studies are used in systematic reviews of medical AI studies. Assessment of risk of bias is espe

Premature ventricular contractions (PVCs) during recovery of exercise stress testing are associated with increased cardiovascular mortality, but the cause remains unknown. We aimed to evaluate the association of PVCs during recovery with echocardiographic abnormalities, and their combined prognostic performance. Echocardiographic abnormalities [reduced left ventricular (LV) ejection fraction, valv

The motivation for this work has been to simplify the design of regulators for industrial processes. The regulators designed can be regarded as self-tuning regulators. They will serve as a substitute for the time-consuming process of plant experiments, parameter estimation and control design. The regulators can also be used as adaptive regulators for processes with slowly varying parameters. The p

While the twentieth century was dominated by private car usage, shifts towards more sustainable urban mobility, to mitigate environmental damage and increase health benefits, are now taking place. In Scandinavia, several car-free street experiments take form, that span from permanent car-free inner-city plans (i.e. Oslo) to temporary interventions (i.e. pop-up plaza and parklets) to shift the use

Diversification of cropping and farming systems is a central agroecological principle, which may improve resource use efficiency, reduce pests and diseases, diversify income sources, and enhance the resilience of the production. The main objective of this study was to identify challenges related to the sustainability of organic cropping systems that were diversified according to one or several of

Objectives: This is a protocol for a Cochrane Review (methodology). The objectives are as follows:. To systematically review the current literature describing the development, content, and measurement properties of clinical rating scales for the assessment of pain in newborn infants.

Most adaptive controllers do not assume any a priori knowledge about the process to be cont rolled. In most situations there is, however, some knowledge about the process. This knowledge should be used to improve the performance compared to the “black box” approach of earlier adaptive controllersThe a priori knowledge is in this paper used in the estimation of the process and also in the design of
