PURPOSE: Distal ulnar Hounsfield unit (HU) measurements obtained from computed tomography (CT) scans of the wrist can be used to accurately screen for low bone mineral density. It is unknown whether HU measurements can also predict the risk of future fragility fractures. Therefore, the purpose of this study was to determine if the HU values of the distal ulna correlate to fragility fracture risk.M

BACKGROUND: Individuals with neovascular age-related macular degeneration (AMD) have altered number and distribution of retinal macrophages and show changes in circulating antibodies. We wanted to investigate the corresponding precursors, with subpopulations. We therefore measured monocyte and B-lymphocyte populations in individuals with neovascular AMD.DESIGN: This was an observational case-contr

BACKGROUND: Osteoporosis is a costly and morbid disease with the first presentation often with a fragility fracture. The purpose of this study was to assess whether Hounsfield unit (HU) measurements on shoulder computed tomography could identify patients at risk of osteoporosis and aid in its diagnosis.METHODS: We identified patients who had both a computed tomography scan of the glenoid and a dua

PURPOSE: The purpose of this study was to determine the frequency with which osteoporosis topics (screening, medical treatment, and fracture prevention) are presented at national hand surgery meetings. This was compared with the frequency of the same topics presented at the Orthopaedic Trauma Association (OTA) annual meetings.METHODS: The annual meeting programs for the American Society for Surger

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

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

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

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

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

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

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

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

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

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

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

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

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
