Criteria for ECG detection of acute myocardial ischemia : Sensitivity versus specificity

Background: Criteria for electrocardiographic detection of acute myocardial ischemia recommended by the Consensus Document of ESC/ACCF/AHA/WHF consist of two parts: The ST elevation myocardial infarction (STEMI) criteria based on ST elevation (ST↑) in 10 pairs of contiguous leads and the other on ST depression (ST↓) in the same 10 contiguous pairs. Our aim was to assess sensitivity (SE) and specif

Uncontracted basis sets for ab initio calculations of muonic atoms and molecules

In this work, we investigated muonic atoms and molecules from a quantum chemist's viewpoint by incorporating muons in the CASSCF model. With the aim of predicting muonic X-ray energies, primitive muonic basis sets were developed for a selection of elements. The basis sets were then used in CASSCF calculations of various atoms and molecules to calculate muonic excited states. We described the influ

Monitoring Mangrove forest landcover changes in the coastline of Bangladesh from 1976 to 2015

This study used multi-date Landsat images to quantify mangrove cover changes in the whole of Bangladesh from 1976 to 2015. Images were pre-processed with an atmospheric correction using Dark Object Subtraction (DOS) and Relative Radiometric Normalization (RRN) using Pseudo-Invariant Features (PIFs). Land Use/Land Cover (LU/LC) classification map was generated using Maximum Likelihood (MaxLike) alg

Axial turbine design for a twin-turbine heavy-duty turbocharger concept

In the process of evaluating a parallel twin-turbine pulseturbocharged concept, the results considering the turbine operation clearly pointed towards an axial type of turbine. The radial turbine design first analyzed was seen to suffer from suboptimum values of flow coefficient, stage loading and blade-speed-ratio. Modifying the radial turbine by both assessing the influence of "trim" and inlet ti

Antithrombotic treatment and risk of complications after head and neck full thickness skin graft surgery

Head and neck skin cancer surgery using a full thickness skin graft is a common procedure. Evidence concerning the effects of perioperative antithrombotic treatment on complications is limited. The aim of this study was to evaluate whether perioperative antithrombotic treatment is associated with risk of necrosis, bleeding or infection after full thickness skin graft surgery. Retrospective single-

Evaluation of CMIP5 models for west and southwest Iran using TOPSIS-based method

GCMs (general circulation models) are main tools for generating climate projections for climate change research in hydrology and water resources. Accordingly, evaluating the performance of these models in simulating future climate is very important for choice of proper models. In this study, performance of 20 Coupled Model Intercomparison Project Phase 5 (CMIP5) model series was assessed using a t

Enhanced heat transfer and thermal performance of a blade with tree-shaped film cooling channels

Modern film cooling is an essential method to protect the turbine blade from the hot gas, and the issue about how to improve the film cooling performance has attracted much attention. In this study, a tree-shaped film cooling structure is carried out to improve the overall effectiveness and better decrease the metal temperature of the blade at the same time. To validate the superiority of the prop

Infective endocarditis due to Streptococcus dysgalactiae : clinical presentation and microbiological features

Knowledge of infective endocarditis (IE) caused by Streptococcus dysgalactiae (SD) is limited. This study aimed to identify the clinical and microbiological features of SD-caused IE and to investigate any possible synergy between penicillin and gentamicin on SD isolates. Cases of IE 2008–2016 due to SD reported to the Swedish Registry of Infective Endocarditis (SRIE) were identified. Isolates were

A virtual promise of happiness : kinship on the websites of Danish fertility clinics and sperm banks

Each month thousands of people travel across national borders to access assisted reproductive treatments across Europe. The possibility to purchase fertility treatments in a similar way to other products and services has led not only to a clearly defined market place and customer, but has also contributed to scholarly work on critical studies of kinship. To date, however, there has been little res

Participatory parity in schooling and moves towards ordinariness : a comparison of refugee education policy and practice in England and Sweden

Within the current global refugee crisis this paper emphasises the fundamental role of education in facilitating the integration of young new arrivals. It argues that a humanitarian problem of such scale requires a commensurate humanitarian response in the form of socially-just educational policies and practices in resettlement contexts within Europe. Utilising the theoretical concepts, ‘participa

Leptospira interrogans outer membrane protein lipl21 is a potent inhibitor of neutrophil myeloperoxidase

Leptospirosis is a widespread zoonotic and neglected infectious disease of human and veterinary concern that is caused by pathogenic Leptospira species. After entrance in the host, pathogenic leptospires evade the host natural defense mechanisms in order to propagate and disseminate to multiple organs. Myeloperoxidase is an enzyme stored in neutrophils azurophilic granules, and is released upon ne

Improved lumbar infusion test analysis for normal pressure hydrocephalus diagnosis

Objectives: Constant infusion lumbar infusion test (LIT) is an important way to find which patients, of those with signs and symptoms corresponding to normal pressure hydrocephalus (NPH) who will improve from shunt operation. LIT is a stress test on the ability for cerebrospinal fluid re-absorbtion. The aim of this study is to show how the information from LIT can be improved by quantitative analy

Moisture behavior of weathered wood surfaces during cyclic wetting : measurements and modeling

The effects of weathering on the in-service moisture behavior of wood have received only limited attention so far, with much focus being on the effect of photodegradation on the hydrophobicity of the wood surface. The objective of the present study was to examine the effect of weathering surfaces on the overall moisture behavior of wood specimens exposed to short-term cyclic spraying, with special

Baseline Prostate-specific Antigen Level in Midlife and Aggressive Prostate Cancer in Black Men

Background: Prostate-specific antigen (PSA) measurement in midlife predicts long-term prostate cancer (PCa) mortality among white men. Objective: To determine whether baseline PSA level during midlife predicts risk of aggressive PCa in black men. Design, setting, and participants: Nested case-control study among black men in the Southern Community Cohort Study recruited between 2002 and 2009. A pr

Cardiac arrest is rarely seen in children and teenagers. We present a 12-year old girl with cardiac arrest following myocardial infarction, that required prolonged cardiac massage and extracorporeal-membranous-oxygenation (ECMO). At coronary angiography the left main coronary artery (LMCA) was stented for a suspected coronary dissection. The contraction of the heart improved and the ECMO-treatment

Recycling of MSWI-bottom ash in paved constructions in Sweden – A risk assessment

This paper presents results from a risk assessment of recycling pre-treated bottom ash from municipal solid waste incineration as a subbase layer in certain asphalt paved constructions in Sweden. Based on a model for assessing environmental and health risks at contaminated areas, previously developed by the Swedish EPA and by the Swedish Geotechnical Institute, target values for total content and

Medicinsk etik i fokus

Vem avgör vad som är etiskt rätt att göra inom medicin och forskning? Och hur angriper en medicinetiker ett etiskt dilemma? I det här avsnittet möter vi Nils-Eric Sahlin, professor i medicinsk etik vid Lunds universitet och medlem i Statens medicinetiska råd (SMER). Vi pratar bland annat om artificiell intelligens i vården, hur de medicinetiska frågorna sett ut genom historien – och varför majorit
