BACKGROUND: Counting very low levels of leukocytes is technically challenging but mandatory for quality control of leukocyte-depleted plasma. Established assays, such as flow cytometry and counting in the Nageotte chamber, are laborious and expensive. The aim of this study was to test two alternative assays, the cerebrospinal fluid program in the routine hematology analyzer ADVIA 2120 and a fluore

OBJECTIVES: To study the effects on the number of laboratory tests ordered after introduction of cost display (showing the cost in the computerized test ordering system at test ordering and test result delivery) and cost charge (requiring all primary healthcare centers to pay full laboratory costs of the ordered tests). STUDY DESIGN: The study included cost display for secondary healthcare centers

BACKGROUND: Quality control of residual white blood cells (WBCs) and red blood cells (RBCs) in leukoreduced plasma is mandatory. Although technological advances have been made, analysis of quality controls using routine hematology analyzers has not generally been introduced. The aim of this study was to evaluate if the routine hematology analyzer Sysmex XN-10, (Sysmex Nordic ApS) could be used for

Currently used methodologies for quality control of residual leukocytes and erythrocytes in leukocyte-depleted plasma are either expensive or time-consuming. It has been proposed that urine dipsticks could be used as a screening method for residual erythrocytes. The aim was, therefore, to evaluate if urine dipsticks could be used to detect residual erythrocytes and also residual leukocytes in leuk

Background: The recently launched high-throughput assays for detecting antibodies against SARS-CoV-2 has contributed to the managing strategies for the COVID-19 pandemic. This study aimed to investigate the performance of three high-throughput assays and one rapid lateral flow test relative to regulatory authorities' recommended criteria. Methods: A total of 315 samples, including 150 pre-pandemic

Objectives: Spectrophotometric absorption curve analysis of cerebrospinal fluid (CSF) for oxyhaemoglobin and bilirubin is necessary to accurately diagnose subarachnoid haemorrhage (SAH) in patients with typical symptoms but with negative findings on X-ray examinations. In this study, we evaluated the performance of two methods for interpreting absorption curves; one method from the United Kingdom

Terrestrial ecosystems regulate climate by absorbing about one-third of anthropogenic CO2 emissions. Monitoring carbon, water, and energy fluxes is essential for understanding ecosystem responses to climate change. However, existing flux datasets lack sufficient spatial resolution and consistency needed for fragmented landscapes like UK agricultural areas. This study presents the Unified FLUXes (U

This study aimed to describe differences in prevalence and the long-term presence of nucleocapsid antibodies (N-antibodies) elicited by SARS-CoV-2 infection in a Swedish blood donor population not subjected to lockdown. We tested 20,651 blood donor samples for nucleocapsid antibodies from the beginning of March 2020 and 27 months onwards using the Roche Elecsys Anti-SARS-CoV-2 assay. The proportio

Introduction: Primary ciliary dyskinesia (PCD) is a rare, congenital condition in which impaired ciliary function leads to bronchiectasis and progressive lung function decline. Bronchiectasis development is believed to involve infection and inflammation but is incompletely understood. Macrophages play a central role in cellular immune response, contributing to both pathogen clearance and immunoreg

Purpose: Humoral immunity proteins—immunoglobulins, complement proteins, and antimicrobial peptides—have key antimicrobial and immunomodulatory functions in sepsis. We hypothesised that their circulating levels are lower in non-survivors, potentially resulting in impaired bacterial clearance and persistent or recurrent infections. Methods: We performed a systematic review and meta-analysis evaluat

Chemical pollution is identified as a significant driver of biodiversity loss, raising concerns about the effectiveness of current environmental risk assessment (ERA) practices. Conventional ERA approaches primarily rely on the endpoints of mortality, growth, and reproduction, often failing to capture the full scope of potential effects that chemicals can have on organisms. This is potentially pro

There is a long tradition in using genetically based color polymorphisms in natural populations to study evolutionary processes. Despite growing evidence for continuous phenotypic variation within discrete morphs, we still know little about how this shapes selective dynamics. Here, using 43 years of plumage color data from a Finnish tawny owl population (Strix aluco), we show that gray and brown m

This dissertation examines the construction of monumental synagogues in nineteenth-century Sweden as a means through which Jewish communities articulated public presence, negotiated belonging, and translated aspirations for civic inclusion into durable architectural form. Focusing on five purpose-built synagogues in Gothenburg (1855), Norrköping (1858), Stockholm (1870), Karlstad (1899), and Malmö

Introduction: To address communication barriers, minimise social isolation, prevent psychosocial illness and increase the independence of Deaf older adults, a mobile care team consisting of Deaf assistant nurses using sign language was initiated and developed by a nongovernmental organisation in a region in southern Sweden. Aim: To describe Deaf older adults’ experiences receiving support from an

Aims The prevalence of adults with congenital heart disease (ACHD) is rising due to improved paediatric care. In parallel, updated data on prognosis in adult life are needed. Objectives The aim was to calculate the standardized mortality ratio (SMR) and death rates in ACHD compared to the general population. Methods and results Data were obtained from the national register of congenital heart dise
