Can a technology turn (also) into a symbol? The 3D printers case

The 3D printing industry has been recently affected by two events: the fact that open source (OS) business models are getting momentum, and the widespread diffusion of the Maker Movement. We argue that 3D printers can be conceptualised as innovations which embody both technological and symbolic aspects. If innovations of the first type are solely adopted for their technical utility, innovations wh

Efficacy and safety of dronedarone by atrial fibrillation history duration : Insights from the ATHENA study

Background: Atrial fibrillation/atrial flutter (AF/AFL) burden increases with increasing duration of AF/AFL history. Hypothesis: Outcomes with dronedarone may also be impacted by duration of AF/AFL history. Methods: In this post hoc analysis of ATHENA, efficacy and safety of dronedarone vs placebo were assessed in groups categorized by time from first known AF/AFL episode to randomization (ie, dur

All the organisms have developed defensive against different (parasites, harsh environmental conditions or contaminants) to which they should face in their environments. To deal with these selective factors, birds have developed defensive mechanisms such as the uropygial gland, which produces a secretion acting as a physico-chemical defensive barrier against a high diversity of ectoparasites and p

Disturbance in the oropharyngeal microbiota in relation to antibiotic and proton pump inhibitor medication and length of hospital stay

The aim of this study was to investigate the appearance of a disturbed oropharyngeal microbiota during hospitalization and explore the patient characteristics that maybe associated with such a disturbance. Oropharyngeal swabs were collected from 134 patients at hospital admission and every 3–4 days thereafter. The samples were cultivated to determine the presence of a disturbed microbiota, which,

Housing Assessment Tools Developed or Adapted for Use in East and Southeast Asia : A Scoping Review

An overview of housing assessment tools developed or adapted for research use in East and Southeast Asia is currently lacking. A scoping review was conducted to address this knowledge gap. PubMed, Web of Science and CINAHL were searched for relevant scientific literature, and 22 articles were selected. Besides study-specific checklists, two assessment tools validated for use in Asia and three vali

High-temperature oxidation of propanol isomers in the mixtures with N2O at high Ar dilution conditions

This work provides, for the first time, new information regarding the kinetics interaction between N2O and propyl alcohol isomers. To this end, the formation and consumption of atomic oxygen were measured behind the reflected shock waves using Atomic Resonance Absorption Spectroscopy (ARAS) technique for 1–10 ppm n- i-propanol + 10 ppm N2O + Ar mixtures, at 2–3 bar and over a wide temperature rang

Artificial intelligence-based detection of lymph node metastases by PET/CT predicts prostate cancer-specific survival

Introduction: Lymph node metastases are a key prognostic factor in prostate cancer (PCa), but detecting lymph node lesions from PET/CT images is a subjective process resulting in inter-reader variability. Artificial intelligence (AI)-based methods can provide an objective image analysis. We aimed at developing and validating an AI-based tool for detection of lymph node lesions. Methods: A group of

Experimental study and analysis of radiation heat fluxes received by a floor beneath an inclined ceiling

This study experimentally investigates the radiation heat flux distribution received on the floor due to fire plume impinging upon an inclined ceiling, which has not been quantified previously. The radiation heat fluxes were measured on the floor for 160 experimental conditions, involving various fire source heat release rates, source-ceiling heights, angles of ceiling inclination and dimensions (

Development of highly biocompatible neuro-electronic interfaces towards monitoring authentic neuronal signaling in the brain

Background: To understand how the neuronal circuits in the brain process information there is a need for novelneuro-electronic interfaces that can interact chronically with brain tissue with minimal disturbance of thephysiological conditions in the tissue, in awake and freely moving animals. For this, there is a need for implantableneuro-electronic interfaces that are mechanically compliant with t

Interatrial Block Predicts Atrial Fibrillation and Total Mortality in Patients with Cardiac Resynchronization Therapy

Background: Interatrial block (IAB) and abnormal P-wave terminal force in lead V1 (PTFV1) are electrocardiographic (ECG) abnormalities that have been shown to be associated with new-onset atrial fibrillation (AF) and death. However, their prognostic importance has not been proven in cardiac resynchronization therapy (CRT) recipients. Objective: To assess if IAB and abnormal PTFV1 are associated wi

Sharing indoor space : Stakeholders’ perspectives and energy metrics

The sharing of indoor space can improve space and energy efficiency. The drivers and barriers to space-sharing initiatives are investigated from the perspectives of building users and building sector practitioners, based on interviews and a workshop. The role of energy performance metrics in promoting space efficiency is further analysed through a literature review. From the users’ perspective, sp

“So I am stuck, but it´s OK” : residential reasoning and housing decision-making of low-income older adults with disabilities in Baltimore, Maryland

Housing preferences and housing decision-making in later life are critical aspects of aging in place, which is a public health priority in many Western countries. However, few studies have examined the economic, social, and health factors that guide older adults’ preferences and decisions about where to live, and even less so among older adults with low income or disabilities who may face greater

Using machine learning to enrich building databases : Methods for tailored energy retrofits

Building databases are important assets when estimating and planning for national energy savings fromenergy retrofitting. However, databases often lack information on building characteristics needed to determine the feasibility of specific energy conservation measures. In this paper, machine learning methods are used to enrich the Swedish database of Energy Performance Certificates with building c

Psychiatric disorders in offspring of childhood or adolescent central nervous system tumor survivors : a national cohort study

BACKGROUND: Children experience a higher risk of psychiatric problems when their parents are diagnosed with cancer. However, the psychological effect among offspring who are born after parental cancer diagnosed in childhood or adolescence is unknown. We aimed to investigate the risk of psychiatric disorders in children of survivors with childhood or adolescent central nervous system (CNS) tumors.M

Association of post-diagnostic use of cholera vaccine with survival outcome in breast cancer patients

BACKGROUND: Expensive cancer treatment calls for alternative ways such as drug repurposing to develop effective drugs. The aim of this study was to analyse the effect of post-diagnostic use of cholera vaccine on survival outcome in breast cancer patients.METHODS: Cancer diagnosis and cholera vaccination were obtained by linkage of several Swedish national registries. One vaccinated patient was mat

Drug Repurposing in Oncology : Current Evidence and Future Direction

BACKGROUND: Drug repurposing, the application of known drugs and compounds with a non-oncology primary purpose, might be an attractive strategy to offer more effective treatment options to patients with cancer at a low cost and reduced time.METHODS: This review described a total of 10 kinds of non-oncological drugs from more than 100 mechanical studies as well as evidence from population-based stu
