Comparative cytological and histological assessment of 828 primary soft tissue and bone lesions, and proposal for a system for reporting soft tissue cytopathology

Introduction: The aim of the study was to evaluate the diagnostic utility of fine needle aspiration (FNA) cytology and core needle biopsies (CNBs) in a series of primary soft tissue and bone lesions and to test a possible system for reporting results of FNA cytology of soft tissue lesion. Methods: This retrospective study encompassed 828 primary soft tissue and bone lesions, analysed with FNA, CNB

Oral contraceptive use and risk of suicidal behavior among young women

Background. Oral contraceptive use has been previously associated with an increased risk of suicidal behavior in some, but not all, samples. The use of large, representative, longitudinally-assessed samples may clarify the nature of this potential association. Methods. We used Swedish national registries to identify women born between 1991 and 1995 (N = 216 702) and determine whether they retrieve

Hinchey I and II diverticular abscesses : long-term outcome of conservative treatment

BACKGROUND: The management of diverticular disease and its complications are an increasing burden to the health system. The natural history of conservatively managed diverticular abscesses (Hinchey I and II) is poorly described and it remains open to debate whether subsequent sigmoid resection is indicated after conservative management. This observational study compares outcomes of patients treate

Tumor and nodal staging of colon cancer : accuracy of preoperative computed tomography at a Swedish high-volume center

Background: When deciding treatment options for patients with colon cancer, accurate staging is required. In Sweden, the main preoperative evaluation modality to determine tumor and nodal stage is computed tomography (CT).Purpose: The aim of this study was to investigate how well the preoperative (CT-determined) clinical tumor and nodal stage (cTN) correlated with the postoperative histopathologic

Silent variant in F8:c.222G>T (p.Thr74Thr) causes a partial exon skipping in a patient with mild hemophilia A

One of the challenges of genetic testing in patients with hemophilia A is the interpretation of sequence variants. Here we report a silent variant found in exon 2 in the F8 gene in a 47-year-old patient with a previous von Willebrand disease (VWD) type 1 diagnosis. Clinically he had mild bleeding symptoms restricted to prolonged bleeding from minor wounds. Sanger sequencing of F8 gene using genomi

Islet Function in the Pathogenesis of Cystic Fibrosis-Related Diabetes Mellitus

Cystic fibrosis-related diabetes mellitus (CFRD) is the most common non-pulmonary co-morbidity in cystic fibrosis (CF). CF is caused by mutations in the cystic fibrosis transmembrane conductance regulator gene (CFTR), which leads to aberrant luminal fluid secretions in organs such as the lungs and pancreas. How dysfunctional CFTR leads to CFRD is still under debate. Both intrinsic effects of dysfu

The composite channel method : Efficient experimental evaluation of a realistic MIMO terminal in the presence of a human body

The immediate environment of the transmit (TX) and receive (RX) antennas, including the antenna casings and the users holding the antennas, has a strong impact on the propagation channel and thus on wireless systems. In this paper we experimentally evaluate a method that synthetically combines double-directional measurements of the propagation channel (without the user influence) with measured ant

Probing surface-sensitive redox properties of VOx/TiO2 catalyst nanoparticles

Redox processes of oxide materials are fundamental in catalysis. These processes depend on the surface structure and stoichiometry of the oxide and are therefore expected to vary between surface facets. However, there is a lack of direct measurements of redox properties on the nanoscale for analysing the importance of such faceting effects in technical materials. Here, we address the facet-depende

Training the trainers : Finding new educational opportunities in the virtual world

The COVID-19 pandemic has disrupted scientific gatherings and conferences, opening up opportunities for virtual learning platforms. Realizing the potential of online academic exchanges, the World Psychiatric Association (WPA) also developed virtual avenues and information systems for capacity building of mental health professionals across the world. Among its first such initiatives, the WPA organi

Modelling temperature dynamics in sewer systems – Comparing mechanistic and conceptual modelling approaches

The vast majority of the energy consumed for urban water services is used to heat tap water. Heat recovery from wastewater is consequently an area of rapidly growing concern, both in research and by commercial interest, promoting the path towards a circular economy. To facilitate a system-wide evaluation of heat recovery from wastewater, this paper compares two one-dimensional models (mechanistic

Structures of subcontracting : Work organisation, control, and labour in the Swedish building sector

Svensk byggindustri är under förändring. Stora delar av produktionen läggs idag ut på entreprenad och byggföretag förlitar sig på underentreprenörer i större utsträckning än tidigare. Som en del av en global trend av kostnadsreducering inom byggindustrin, försöker byggföretag minimera antalet anställda hantverkare och istället utkontraktera arbete till underentreprenörer i strävan efter organisatoThe organisation of work in the Swedish building sector is changing due to increased subcontracting and the adoption of construction management. In this study, construction management refers to a specific subcontracting regime, in which contractors externalise all parts of the production process and organise work through subcontractors. Echoing global trends of cost-cutting, this externalisation b

Raising Capital to Raise Crops : Slave Emancipation and Agricultural Output in the Cape Colony

Agricultural output fluctuated worldwide after the emancipation of slaves. The usual explanation is that former slaveholders now lacked labor. This is not the full story: slaves were not just laborers but capital investments to support production. Using databases covering more than 40 years from Stellenbosch in the British Cape Colony, this study measures changes in output before and after emancip

Resilience to shrinking as a catch-up strategy: a comparison of Brazil and Indonesia, 1964–2010

Development economics has long focused on growth patterns to explain countries’ ability to catch up and forge ahead. We argue, however, that resilience to economic shrinking matters more. Using the examples of Brazil and Indonesia, we propose that a framework consisting of social capabilities – namely structural transformation, autonomy, and inclusion – can explain why Indonesia is more resilient

Compliance to a Gluten-Free Diet in Swedish Children with Type 1 Diabetes and Celiac Disease

Children with type 1 diabetes (T1D) are at increased risk of celiac disease (CD). The replacement of insulin in T1D, and the exclusion of gluten in CD, are lifelong, burdensome treatments. Compliance to a gluten-free diet (GFD) in children with CD is reported to be high, while compliance in children with both diseases has scarcely been studied. To examine compliance to a GFD in children with both

A search for transiting planets around hot subdwarfs : I. Methods and performance tests on light curves from Kepler, K2, TESS, and CHEOPS

Context. Hot subdwarfs experienced strong mass loss on the red giant branch (RGB) and are now hot and small He-burning objects. These stars constitute excellent opportunities for addressing the question of the evolution of exoplanetary systems directly after the RGB phase of evolution.Aims. In this project we aim to perform a transit survey in all available light curves of hot subdwarfs from space

Pan-genomic sequencing reveals actionable cdkn2a/2b deletions and kataegis in anaplastic thyroid carcinoma

Anaplastic thyroid carcinoma (ATC) is a lethal malignancy characterized by poor response to conventional therapies. Whole-genome sequencing (WGS) analyses of this tumor type are limited, and we therefore interrogated eight ATCs using WGS and RNA sequencing. Five out of eight cases (63%) displayed cyclin-dependent kinase inhibitor 2A (CDKN2A) abnormalities, either copy number loss (n = 4) or trunca

Targeted genomic investigations in a population-based cohort of mantle cell lymphoma reveal novel clinically relevant targets

Mantle cell lymphoma (MCL) is an aggressive B-cell neoplasm that follows a heterogeneous clinical course. Recurrent mutations have been described, but their applicability in the clinical setting is currently limited. The main reasons are challenges in the sequencing of DNA retrieved from formalin-fixed tissue commonly used for tissue collection in clinical biobanks. In this study, we sequenced 77
