Fabrication of Single-Crystalline InSb-on-Insulator by Rapid Melt Growth
InSb has the smallest bandgap and highest electron mobility among III-V semiconductors and is widely used for photodetectors and high-frequency electronic applications. Integration of InSb directly on Si would drastically reduce the fabrication cost and enable new applications, however, it is very challenging due to its 19% lattice mismatch with Si. Herein, the integration of single-crystalline In
Predictive molecular pathology in the time of coronavirus disease (COVID-19) in Europe
Aims Lung cancer predictive biomarker testing is essential to select advanced-stage patients for targeted treatments and should be carried out without delays even during health emergencies, such as the coronavirus (COVID-19) outbreak. Methods Fifteen molecular laboratories from seven different European countries compared 4 weeks of national lockdown to a corresponding period in 2019, in terms of t
Building a bridge between patients and transplant healthcare professionals – a descriptive study
This article describes a pathway for collaboration between transplant healthcare professionals and organ recipients. Under the umbrella of the European Society for Organ Transplantation (ESOT) a joint initiative started from three Sections and Committees of ESOT: EDTCO (European Donation and Transplant Coordination Organisation), ETHAP (European Transplant Allied Healthcare Professionals) and ELPA
Similar migration for medial congruent and cruciate-retaining tibial components in an anatomic TKA system : a randomized controlled trial of 60 patients followed with RSA for 2 years
Background and purpose — There is an ongoing debate regarding the appropriate level of constraint in primary TKA. To provide increased stability and better kinematics, more resembling a natural knee, a medial congruent (MC) tibial insert has been introduced. To investigate potential impact on implant migration, we evaluated the cemented Persona TKA, randomizing between MC and cruciate-retaining (C

Performance of Computed Tomography Angiography Before Revascularization Is Associated With Higher Amputation-Free Survival in Rutherford IIb Acute Lower Limb Ischaemia
Background: Acute lower limb ischemia with a motor deficit (Rutherford IIb) needs urgent revascularization to avoid major amputation and mortality. It is unclear whether immediate revascularization without performing CT angiography (CTA) prior to revascularization in Rutherford IIb acute lower limb ischemia (ALI) is associated with better outcomes. Methods: Retrospective observational study of Rut
Increasing bacteremia due to coagulase-negative staphylococci : fiction or reality?
BACKGROUND: The role of coagulase-negative staphylococci (CNS) in bacteremias continues to be controversial. Until the 1970s, CNS were mostly recognized as contaminants, being part of the cutaneous flora. Since then, several studies have reported increasing incidence and severity of infections due to CNS.PURPOSE: To review the literature concerning the epidemiology of CNS bacteremia in the United
Two Eyes Are Better Than One-Binocular Summation of Dark Vision in Healthy Individuals and Patients with Chronic Respiratory Disease
We compared monocular and binocular absolute thresholds of dark adaptation in two separate study populations. Eighteen healthy individuals (Group A) and 13 patients with chronic respiratory insufficiency (Group B) were examined three times each by computerised dark adaptometry with simultaneous but separate recordings from each eye and binocularly. The respiratory patients received oxygen suppleme
Respiratory responses to intravenous infusion of sodium lactate in male and female Wistar rats
In patients with panic disorder or premenstrual dysphoria, anxiety attacks can be triggered by intravenous administration of sodium lactate. Since respiratory symptoms, such as hyperventilation and shortness of breath, are characteristic features of spontaneous as well as lactate-induced panic, an involvement of central or peripheral chemoreceptors in this reaction has been suggested. In the prese

Carfilzomib and dexamethasone maintenance following salvage ASCT in multiple myeloma : A randomised phase 2 trial by the Nordic Myeloma Study Group
Objective: We investigated the efficacy and safety of carfilzomib-containing induction before salvage high-dose melphalan with autologous stem-cell transplantation (salvage ASCT) and maintenance with carfilzomib and dexamethasone after salvage ASCT in multiple myeloma. Methods: This randomised, open-label, phase 2 trial included patients with first relapse of multiple myeloma after upfront ASCT wh
Clinical evolution, genetic landscape and trajectories of clonal hematopoiesis in SAMD9/SAMD9L syndromes
Germline SAMD9 and SAMD9L mutations (SAMD9/9Lmut) predispose to myelodysplastic syndromes (MDS) with propensity for somatic rescue. In this study, we investigated a clinically annotated pediatric MDS cohort (n = 669) to define the prevalence, genetic landscape, phenotype, therapy outcome and clonal architecture of SAMD9/9L syndromes. In consecutively diagnosed MDS, germline SAMD9/9Lmut accounted f
alpha-synuclein: amyloid fibrils and interactions with lipid membranes
The second most common neurodegenerative disease, Parkinson’s disease, is linked with an amyloid forming protein, alpha-synuclein. Hallmarks of Parkinson’s disease are progressive loss of dopaminergic neurons and accumulation of intraneuronal inclusions termed Lewy bodies. Major components of Lewy bodies are amyloid fibrils formed by alpha-synuclein and various lipids and cell organelles. In this
The Microbiology of Infective Native Aortic Aneurysms in a Population-Based Setting
Objective: The aim was to describe the microbiology of surgically treated infective native (mycotic) aortic aneurysms (INAAs), and associated survival and development of infection-related complications (IRCs). Methods: Data were pooled from 2 nationwide studies on surgically treated patients with INAAs in Sweden, between 1994 – 2016. Patients were grouped and analyzed according to culture results:
Lifetime Trauma History and Cognitive Functioning in Major Depression and Their Role for Cognitive-Behavioral Therapy Outcome
Background: While cognitive-behavioral therapy (CBT) is the gold-standard psychological treatment for major depression (MD), non-response and lacking stability of treatment gains are persistent issues. Potential factors influencing treatment outcome might be lifetime trauma history and possibly associated primarily prefrontal-cortex- and hippocampus-dependent cognitive alterations. Method: We inve
Citizen integration in project prioritization methodologies
Expert-led multicriteria methodologies might have significant improvements in terms of relevance and effectiveness when citizen participation is integrated. This inclusion is especially influential regarding urban revitalization projects (URPs) prioritization, which directly affects the conservation of cultural heritage. The objective is to apply an existing multicriteria methodology for URPs’ pri
Single-cell measurements of two-dimensional binding affinity across cell contacts
The two-dimensional (2D) affinity between protein molecules across contacting cells is a key parameter regulating and initiating several cellular processes. However, measuring 2D affinity can be challenging, and experimental data are limited. In addition, the obtained 2D affinities are typically averaged over the cell population. We here present a method to measure 2D affinity on single cells bind
Change and consistency in Acta Radiologica over 100 years
Acta Radiologica celebrates its 100th anniversary in 2021. In this article, the foundation of the journal and its editors are described. During 100 years, the manuscript structure changed from single-author verbose monographs to multi-author collaborations on statistically analyzed research subjects. The authorship changed from purely Nordic authors to a truly international cadre of authors, and t
Validation of the classification for type 2 diabetes into five subgroups : a report from the ORIGIN trial
Aims/hypothesis: Data analyses from Swedish individuals with newly diagnosed diabetes have suggested that diabetes could be classified into five subtypes that differ with respect to the progression of dysglycaemia and the incidence of diabetes consequences. We assessed this classification in a multiethnic cohort of participants with established and newly diagnosed diabetes, randomly allocated to i
