The Health and Occupation Research Network: An Evolving Surveillance System
Carder, Melanie,Hussey, Louise,Money, Annemarie,Gittins, Matthew,McNamee, Roseanne,Stocks, Susan Jill,Sen, Dil,Agius, Raymond M. Occupational Safety and Health Research Institute 2017 Safety and health at work Vol.8 No.3
Vital to the prevention of work-related ill-health (WRIH) is the availability of good quality data regarding WRIH burden and risks. Physician-based surveillance systems such as The Health and Occupation Research (THOR) network in the UK are often established in response to limitations of statutory, compensation-based systems for addressing certain epidemiological aspects of disease surveillance. However, to fulfil their purpose, THOR and others need to have methodologic rigor in capturing and ascertaining cases. This article describes how data collected by THOR and analogous systems can inform WRIH incidence, trends, and other determinants. An overview of the different strands of THOR research is provided, including methodologic advancements facilitated by increased data quantity/quality over time and the value of the research outputs for informing Government and other policy makers. In doing so, the utility of data collected by systems such as THOR to address a wide range of research questions, both in relation to WRIH and to wider issues of public and social health, is demonstrated.

Visualization of Magnetic Domains in Electrical Steel Using High-Resolution Dark-Field Imaging
김영주,김종열,Daniel Seth Hussey,Oh Youl Kwon,이승욱 대한금속·재료학회 2019 대한금속·재료학회지 Vol.57 No.6
Electrical steel is a soft magnetic steel material used in electric devices such as transformers and motors. The performance of these electric devices is primarily related to the magnetic properties of electrical steel, and the assessment of the magnetic properties of electrical steel has been considered an important topic. We use neutron grating interferometry, which is an imaging technique for visualizing the magnetic domain of electrical steel as the evaluation of magnetic properties. The dark-field image provided by neutron grating interferometry shows a sensitive contrast with respect to the magnetic domain of electrical steel due to the small angle neutron scattering generated at the domain wall. The Talbot-Lau interferometer was installed, and the feasibility test of high-resolution dark-field imaging was conducted at cold neutron imaging beamline of the NIST Center for Neutron Research. The dark-field image of electrical steel was compared with the magnetic domain image observed by the Bitter pattern based on the magnetic powder method to prove the validity of neutron grating interferometry. The dark-field image visualizes the magnetic domains of electrical steel, more detailed domain walls regardless of laser-irradiated lines than Bitter pattern result.

Purpose: We aimed to describe our technique for and experience with elective endovascular aneurysm repair using EndoAnchors under local anesthesia. Materials and Methods: We included seven patients with abdominal aortic aneurysms who underwent endovascular aneurysm repair using EndoAnchors with a standard regimen consisting of local anesthesia, intravenous sedation, and analgesia. The procedural and follow-up details were retrospectively reviewed. Results: Six out of seven infrarenal abdominal aortic aneurysms were successfully treated with endovascular aneurysm repair using primary EndoAnchors under local anesthesia. One patient was converted to general anesthesia due to acute aneurysm thrombosis independent of EndoAnchor deployment during the procedure. Remifentanyl infusions of up to 3.2 mg/min, morphine doses up to 6 mg (median, 0.5 mg), and midazolam doses of up to 4 mg (mean, 1.4 mg) were used. The mean theater time was 83 minutes (range, 60–130 minutes). Two patients were discharged on day 0, and the mean hospital stay was one day. All patients were alive between 484 and 1,128 days post-procedure, with no aneurysm-specific reintervention. Conclusion: The combination of local anesthesia, intravenous sedation, and analgesia is a viable strategy for timely and effective endovascular aneurysm repair using EndoAnchors. This technique may allow endovascular repair of more ruptured aneurysms using EndoAnchors with potential survival benefits.

Background: The aim of this study was to determine if there were significant differences in glenohumeral joint morphology between North American and East Asian populations that may influence sizing and selection of shoulder arthroplasty systems. Methods: Computed tomography reconstructions of 92 North American and 58 East Asian patients were used to perform 3-dimensional measurements. The proximal humeral position was normalized in all patients by aligning it with the scapular plane utilizing anatomic landmarks. Measurements were performed on the humerus and scapula and included coronal and axial humeral head radius, humeral neck shaft and articular arc angles, glenoid height and width, and critical shoulder angle. Glenohumeral relationships were also measured and included lateral distance to the greater tuberosity and acromion, abduction lever arm, and acromial index. Parametric and nonparametric statistical analyses were used to compare population metrics. Results: East Asian glenohumeral measurements were significantly smaller for all linear metrics (p < 0.05), with the exception of acromial length, which was greater than in the North American cohort (p < 0.001). The increase in acromial length affected all measurements involving the acromion including abduction lever arms. No difference was found between the neck shaft and articular angular measurements. Conclusions: The East Asian population exhibited smaller shoulder morphometrics than their North American cohort, with the exception of an extended acromial overhang. The morphologic data can provide some additional factors to consider when choosing an optimal shoulder implant for the East Asian population, in addition to creating future designs that may better accommodate this population.

<P><B>Abstract</B></P> <P>Micrometer to centimeter scale analyses of the crystalline phase volume fractions in a trip-assisted duplex stainless steel were performed under loading using electron backscatter diffraction (EBSD), in situ neutron diffraction, and energy selective neutron imaging (ESNI) methods. In contrast to the localized investigations of EBSD, ESNI provides macroscopic spatial distributions in a volume-averaged manner over the entire specimen with a spatial resolution of about 65 μm. The ESNI shows that the martensite is concentrated on the necking region and estimates its volume fraction of 14% at a strain of 0.2, which is comparable to the neutron diffraction result.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
