Non-urgent and urgent telephone nursing services are increasing globally, and phenomenographic research has shown that how work is understood may influence work performance. This descriptive study makes a qualitative inductive investigation of understandings of emergency medical dispatch center work among registered nurses. Twenty-four registered nurses at three mid Swedish emergency medical dispatch centers were interviewed. Analysis based on phenomenographic principles identified five categories in the interviews (i) Assess, prioritize, direct, or refer; (ii) Facilitate ambulance nursing work; (iii) Perform nursing care; (iv) Always be available for the public; and (v) Have the person behind the patient in mind. The first constitutes the basis of the work. The second emphasizes cooperation with and support for the ambulance staff. The third entails remotely providing nursing care, whilst the fourth stresses serving the entire population. The fifth and most comprehensive way of understanding work involves having a holistic view of the person in need, including person-centered care. Provision of high-quality emergency medical dispatch center work involves all categories. Combined, they constitute a “work map,” valuable for reflection, competence development, and introduction of new staff.Detecting genetic regions under selection in structured populations is of great importance in ecology, evolutionary biology and breeding programmes. We recently proposed EigenGWAS, an unsupervised genomic scanning approach that is similar to F ST but does not require grouping information of the population, for detection of genomic regions under selection. The original EigenGWAS is designed for the random mating population, and here we extend its use to inbred populations. We also show in theory and simulation that eigenvalues, the previous corrector for genetic drift in EigenGWAS, are overcorrected for genetic drift, and the genomic inflation factor is a better option for this adjustment. Applying the updated algorithm, we introduce the new EigenGWAS online platform with highly efficient core implementation. Our online computational tool accepts plink data in a standard binary format that can be easily converted from the original sequencing data, provides the users with graphical results via the R-Shiny user-friendly interface. We applied the proposed method and tool to various data sets, and biologically interpretable results as well as caveats that may lead to an unsatisfactory outcome are given. The EigenGWAS online platform is available at http://www.eigengwas.com, and can be localized and scaled up via R (recommended) or docker.
Proper arteriovenous fistula (AVF) management is crucial to avoid AVF complications and prolong its useful life for maintenance haemodialysis (MHD).
Retrospective cohort study.
Patients on MHD who underwent AVF surgery at the Wuhan Third Hospital between January 2018 and July 2018.
A total of 144 patients were included, with 56 in the integrated group and 88 in the routine group. There were no differences between the two groups in terms of sex (p=.61), age (p=.62) and type of primary kidney disease (p>.99). At 1year, the integrated group had significantly fewer fistula-related complications than the routine group (3.6% versus. 23.9%, p<.001). AVF functional scores were lower in the integrated group compared with the routine group (0.1±0.5 versus. 0.8±0.8, p<.001). The pain scores were lower in the integrated group than in the routine group (1.2±0.4 versus. 1.8±0.9, p<.001).

Oxidative stress is implicated in the insidious loss of muscle mass and strength that occurs with age. However, few studies have investigated the role of iron, which is elevated during ageing, in age-related muscle wasting and blunted repair after injury. We hypothesized that iron accumulation leads to membrane lipid peroxidation, muscle wasting, increased susceptibility to injury, and impaired muscle regeneration.
To examine the role of iron in age-related muscle atrophy, we compared the skeletal muscles of 3-month-old with 22- to 24-month-old 129SvEv FVBM mice. We assessed iron distribution and total elemental iron using laser ablation inductively coupled plasma mass spectrometry and Perls’ stain on skeletal muscle cross-sections. In addition, old mice underwent ischaemia-reperfusion (IR) injury (90min ischaemia), and muscle regeneration was assessed 14days after injury. Immunoblotting was used to determine lipid peroxidation (4HNE) and iron-related proteins. To determine whether muscle iron content canlate to structural improvements.
Muscles from old mice have increased iron levels, which are associated with increased lipid peroxidation, increased susceptibility to IR injury, and impaired muscle regeneration. MMP-9-IN-1 nmr Our results suggest that iron is involved in effective muscle regeneration, highlighting the importance of iron homeostasis in muscle atrophy and muscle repair.

To evaluate the influence of 2.2mm clear corneal incision (CCI) features in surgically induced astigmatism (SIA) and higher-order aberrations (HOAs) after cataract surgery.
Right eyes of 92 subjects receiving 2.2mm incision cataract surgery were involved. A total of 38 eyes were categorized as the intact incision group, and 54 eyes were the defective incision group. Pre- and postoperative (1month and 6months) corneal astigmatism and HOAs on anterior and posterior corneal surfaces, corneal volume, and corneal thickness (CT) were measured using Pentacam. The CCI features including incision length (IL), incision angles, distance from incision to central cornea (Dis-En/Ex), and CT at incision site were quantified using AS-OCT.
The defective incision group showed shorter IL and larger incision angles [false discovery rate (FDR) – p<0.05]. Changes in CT at incision site were more pronounced for the defective incision group (FDR – p<0.05). Some SIA parameters were related to the certain specific CCI features, especially IL (FDR – p<0.
