Measurement of Distal Ulnar Hounsfield Units Accurately Predicts Bone Mineral Density of the Forearm

BACKGROUND: Hounsfield unit (HU) measurement obtained from computed tomography (CT) scans of the wrist is a potential new screening method for low bone mineral density (BMD). We hypothesized that HU measurements of the ulnar head obtained from CT scans would correlate with BMD assessed with dual x-ray absorptiometry (DXA) scans of the forearm.METHODS: Patients with both upper-extremity CT and DXA

Entry-inhibitory role of catechins against SARS-CoV-2 and its UK variant

BACKGROUND: The global pandemic caused by a RNA virus capable of infecting humans and animals, has resulted in millions of deaths worldwide. Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) infects the lungs, and the gastrointestinal tract to some extent. Rapid structural mutations have increased the virulence and infectivity of the virus drastically. One such mutated strain known as

Cardiac arrhythmias associated with spinal cord injury

CONTEXT/OBJECTIVES: To review the current literature to reveal the incidence of cardiac arrhythmias and its relation to spinal cord injury (SCI).DATA SOURCE: MEDLINE database, 304 hits, and 32 articles were found to be relevant. The relevant articles all met the inclusion criteria: (1) contained original data (2) on cardiac arrhythmias (3) in humans with (4) traumatic SCI.RESULTS: In the acute pha

EXPLORING THE HYDROMECHANICS OF A HETEROGENEOUS POROUS SANDSTONE: COUPLED IN SITU EXPERIMENTS WITH X-RAY AND NEUTRON IMAGING

In geoengineering, such as oil and gas production, geological CO2 storage, geothermal projects, and environmental remediation, a detailed understanding of the hydraulic and mechanical properties of sandstone properties is crucial. Traditional theories on the hydraulic and mechanical behavior of rocks rely on bulk measurements from boundary sensors, which fail to capture complex heterogeneity in st

Posttraumatiskt stressyndrom (PTSD) och komplex PTSD (CPTSD) : En klinisk kunskapsuppdatering

Post-traumatic stress disorder, PTSD, is a psychiatric diagnosis that describes a condition where one or more very traumatic events, that include life-threatening or extreme psychological stress, have left permanent traces of distress that induce sustained suffering. In this clinical overview, we present current updates in diagnostic criteria and a new diagnosis of complex PTSD, and discuss the pr

Experimental investigation of the response of an a-Si EPID to an unflattened photon beam from an Elekta Precise linear accelerator

The characteristics of an Elekta amorphous silicon (a-Si) electronic portal imaging device (EPID) in response to a 6 MV photon beam generated without a flattening filter, an unflattened beam, have been determined. The characteristics were then compared to those for a conventional photon beam generated with a flattening filter in the beam, a flattened beam, in order to determine the suitability of

Many Maids Make Much Noise

The documented artistic research project (doctoral thesis), Many Maids Make Much Noise, comprises a series of artistic projects focused on the social history of the early twentieth-century British militant campaign for votes for women (known as the suffragette movement). The aim is to try out artistic and educational strategies used within that movement, as a means of ‘reading’ these practices and

Utredning, handläggning och behandling av PTSD och CPTSD

Post-traumatic stress disorder (PTSD) is a disruptive condition associated with great suffering. Fortunately, effective treatments are available. Assessment of children and adolescents with symptoms of PTSD is done within the child and adolescent mental health services. Adults are assessed in primary healthcare settings. In complex conditions with psychiatric comorbidity, assessment is conducted i

The safety of cell saver washing all shed mediastinal blood before re-transfusing it to the patient

Introduction: Cardiotomy suction blood is used in cardiopulmonary bypass (CPB) surgery to maintain blood volume in the CPB system, although it is known to contain micro emboli, cytokines and free plasma hemoglobin. Our aim was to investigate whether cell saver washing the cardiotomy suction blood before re-transfusing it is safe. Methods: This is a retrospective study of 1671 elective coronary art

Four decades of changing dissolved organic matter quality and stoichiometry in a Swedish forest stream

Dissolved organic matter (DOM) concentrations have risen by a factor of two or more across much of Europe and North America during recent decades. These increases have affected the carbon cycle, light regime, drinking water treatability, and the energy and nutrient budgets of lakes and streams. However, while trends in DOM quantity are well characterised, information on how/whether qualitative pro

Governance hurdles for expansion of low trophic mariculture production in Sweden

The study examines the governance of low trophic species mariculture (LTM) using Sweden as a case study. LTM, involving species such as seaweeds and mollusks, offers ecosystem services and nutritious foods. Despite its potential to contribute to blue growth and Sustainable Development Goals, LTM development in the EU and OECD countries has stagnated. A framework for mapping governance elements (in

Three Decades of Changing Nutrient Stoichiometry from Source to Sea on the Swedish West Coast

European ecosystems have been subject to extensive shifts in anthropogenic disturbance, primarily through atmospheric deposition, climate change, and land management. These changes have altered the macronutrient composition of aquatic systems, with widespread increases in organic carbon (C), and declines in nitrogen (N) and phosphorus (P). Less well known is how these disturbances have affected nu

Quantifying nutrient recovery by element flow analysis : Harvest and use of seven marine biomasses to close N and P loops

Anthropogenic consumption of nitrogen (N) and phosphorus (P) has pushed their respective planetary boundaries beyond a safe operating space causing environmental problems, and simultaneously, the depletion of finite mineral P resources is of growing concern. Previous research has found that marine biomass such as kelp, reed and mussels have a high potential for taking up N and P, which could poten

Cost–benefit analysis of beach-cast harvest : Closing land-marine nutrient loops in the Baltic Sea region

Harvesting beach-cast can help mitigate marine eutrophication by closing land-marine nutrient loops and provide a blue biomass raw material for the bioeconomy. Cost–benefit analysis was applied to harvest activities during 2009–2018 on the island of Gotland in the Baltic Sea, highlighting benefits such as nutrient removal from the marine system and improved recreational opportunities as well as co

Marine biomass for a circular blue-green bioeconomy? A life cycle perspective on closing nitrogen and phosphorus land-marine loops

A blue-green bioeconomy revolution is underway in Europe, with particular attention being paid to the development of new or underutilized marine biomass resources. The wild harvest and mariculture of low-trophic non-fed species of marine biomass may be contributing to circular economies, the mitigation of environmental problems such as eutrophication and climate change through the uptake of nutrie

This chapter explores moral and ethical discussions that emerged in Sweden when the number of artificial grass pitches rose substantially. Based on research in the Swedish top-tier football league, named Allsvenskan, I shall present conflicting discourses that appear whenever grass is considered. The grass discussions often take a wider, political turn and reflect attitudes towards developments in

Jämställdhetens betydelse för energieffektivitet i transportsektorn : Slutrapport

Jämställdhet är en högst relevant aspekt för en mer hållbar transportsektor. Det finns genomgående stora skillnader mellan könen vad gäller såväl resvanor och beteende som attityder och värderingar. Skillnaderna i resvanor är så stora att enbart skillnaderna i bilanvändning skulle minska energianvändningen från transportsektorn med en femtedel om män i genomsnitt reste som kvinnor i genomsnitt.
