Macro- and microscopic changes in veins with short-term central venous catheters : an observational autopsy study
BACKGROUND: Centrally inserted central catheters (CICCs) are indispensable in modern healthcare, but unfortunately, come with complications. Catheter-related thrombosis is a well-known complication reported to occur in 5-30% of patients with CICC. There is a paucity of studies that report the incidence of catheter-related thrombosis after the introduction of real-time ultrasound insertion guidance
A concise review of glycerol derivatives for use as fuel additives
Due to renewable fuel mandates worldwide, the increase in biodiesel production has caused an oversupply of low-cost glycerol on the markets, which can negatively affect the sustainability of the biodiesel industry as a whole. In order to avoid that scenario, the transformation of glycerol into value-added products has been investigated, and the production of additives for internal combustion engin
Association Between Severe Nonadherence to Hydroxychloroquine and Systemic Lupus Erythematosus Flares, Damage, and Mortality in 660 Patients From the SLICC Inception Cohort
Objective: The goals of this study were to assess the associations of severe nonadherence to hydroxychloroquine (HCQ), objectively assessed by HCQ serum levels, and risks of systemic lupus erythematosus (SLE) flares, damage, and mortality rates over five years of follow-up. Methods: The Systemic Lupus International Collaborating Clinics (SLICC) Inception Cohort is an international multicenter init
Results of the first nationwide cohort study of outcomes in dialysis and kidney transplant patients before and after vaccination for COVID-19
Background. Patients on kidney replacement therapy (KRT) have been identified as a vulnerable group during the coronavirus disease 2019 (COVID-19) pandemic. This study reports the outcomes of COVID-19 in KRT patients in Sweden, a country where patients on KRT were prioritized early in the vaccination campaign. Methods. Patients on KRT between January 2019 and December 2021 in the Swedish Renal Reg
Surgical management of necrotising enterocolitis in Sweden : A national cohort study
Aim: Necrotising enterocolitis (NEC) is the dominating surgical emergency in preterm neonates. The aims were to investigate indications, surgical management and mortality for surgically treated neonates with NEC. Methods: Data were retrieved from the Swedish Neonatal Quality Register for Swedish neonates with surgically treated NEC from 1 January 2017 to 31 December 2021. Diagnosis was validated b
Wrist osteoarthritis - Impact on daily life, self-management and outcome
For individuals with symptomatic wrist osteoarthritis (OA), pain is the central problem negatively affecting all aspects of life. Despite the recommendations that all OA patients should be offered self-management treatment options, this approach is often lacking for patients with wrist OA. In addition, there has been surprisingly little interest shown in investigating wrist OA patients' wishes and
Diasporic group boundaries and solidarity in the making : collective memory in the anti-war protests in Sweden
Since the eruption of the war in Ukraine in February 2022, both Ukrainian and Russian diasporas in Sweden have been reframing themselves through memories, narratives and symbols. They have been revised in connection to the initial Russian-backed insurgency in eastern Ukraine and the annexation of Crimea (2014), the “homeland” as well as previous diasporic mobilizations in the country of residence.
Characterisation of functional deficits induced by AAV overexpression of alpha-synuclein in rats
Background: In the last decades different preclinical animal models of Parkinson's disease (PD) have been generated, aiming to mimic the progressive neuronal loss of midbrain dopaminergic (DA) cells as well as motor and non-motor impairment. Among all the available models, AAV-based models of human alpha-synuclein (h-aSYN) overexpression are promising tools for investigation of disease progression
Revisiting the P3P Problem
One of the classical multi-view geometry problems is the so called P3P problem, where the absolute pose of a calibrated camera is determined from three 2D-to-3D correspondences. Since these solvers form a critical component of many vision systems (e.g. in localization and Structure-from-Motion), there have been significant effort in developing faster and more stable algorithms. While the current s
Four-view Geometry with Unknown Radial Distortion
We present novel solutions to previously unsolved prob-lems of relative pose estimation from images whose calibration parameters, namely focal lengths and radial distortion, are unknown. Our approach enables metric reconstruction without modeling these parameters. The minimal case for reconstruction requires 13 points in 4 views for both the calibrated and uncalibrated cameras. We describe and imp
HEAP: Health promoting environments for an ageing population : A register and GIS-study of associations between urban greenness and formal social services in Sweden
Machining of Titanium Alloys with a Cemented Carbide Cutting Tools with Tungsten-Based Vacuum-Arc Nitride Coatings
Finding the right coatings for cutting tools is essential in order to increase the tool wear resistance and, thus, to get better surface roughness for the machined workpieces, and to improve productivity. A coating requirements are not only its mechanical and strength properties, but also its response to a given load and a given wear exposure. To expand ideas about the phenomena and mechanisms of
Wear mechanisms in Ti(C,N)-Al2O3 coated carbide during sustainable machining CGI
By replacing conventional gray cast iron (GI) with compacted graphite iron (CGI), automotive industry could keep up with stricter regulations on emissions and demands on higher engine performance. CGI has improved properties as to GI but is more difficult to machine. This study evaluates sustainable machining performance during finish face milling when using minimum quantity lubrication applied ve
Association of beta-blockers beyond 1 year after myocardial infarction and cardiovascular outcomes
Objective Beta-blockers (BB) are an established treatment following myocardial infarction (MI). However, there is uncertainty as to whether BB beyond the first year of MI have a role in patients without heart failure or left ventricular systolic dysfunction (LVSD). Methods A nationwide cohort study was conducted including 43 618 patients with MI between 2005 and 2016 in the Swedish register for co
Veiled Integration : The Use of Headscarves among a Christian Minority in Sweden
In this article, we trace a specific ‘situated bodily practice’, namely the ‘act of covering’ the head with a scarf during liturgy, in a church that has migrated from the Middle East to Sweden. This ‘veiled tradition’ is interpreted as a ‘ritual of migration’ that can cast light on the complexities of re-producing traditions in a new setting, functioning as a ‘cultural prism’ for the question of i
Football training as a non-pharmacological treatment of the global aging population—A topical review
In the present topical mini-review, the beneficial impact of small-sided game football training for the increasing elderly global population is presented. As a multicomponent type of physical activity, football training executed on small pitched with 4–6 players in each team is targeting a myriad of physiological systems and causes positive adaptations of relevance for several non-communicable dis
