ABSTRACTObjectives 1) To develop a fully data-driven framework for automatically identifying patients with a condition from routine electronic primary care records; 2) to identify informative codes (risk factors) of arthropathy conditions in primary care records that can accurately predict a diagnosis of the conditions in secondary care records.
ApproachThis study linked routine primary and secondary care records in Wales, UK held in the SAIL (Secured Anonymised Information Linkage) databank, in which the secondary care records were used as golden standard. As such, we proposed to use machine learning techniques to extract patient information and identify cohorts with a condition from the large and high-dimensional linked dataset using the following phases: data preparation, performed in the machine learning context fashion; pre-selection of initial features, ranking and selecting features into a meaningful subset by using feature selection methods; and identification algorithm development which incorporates mechanisms of tackling the imbalanced nature of the data. This data-driven framework was then validated on an independent dataset, and compared with existing algorithm which had been developed using expert clinician knowledge for arthropathy conditions.
ResultsRheumatoid arthritis (RA) and ankylosing spondylitis (AS) were used to demonstrate the feasibility of this framework. Linking primary care records with the secondary care rheumatology clinical system, we collected 9,657 patients with 1,484 RA patients and 204 AS patients. The proposed framework identified various compact subsets of informative features (risk factors) from 43,100 potential Read codes. Applying to an independent test data, this framework achieved the classification accuracy and positive predictive values (PPVs) of 86.19% and 88.46% respectively for RA and 99.23 % and 97.75% respectively for AS, which are comparable with the performance of clinical knowledge-based method - the accuracy of 85.85%, the PPV of 85.28% for RA and the accuracy of 97.86% , the PPV of 95.65% for AS.
ConclusionThe proposed data-driven framework provides a rapid and cost-effective way of reliably identifying patients with a medical condition from primary care data. It performed as well as the clinically derived algorithm. This framework does not intend to substitute clinical expertise, instead it provides an decision support tool for clinicians during their decision process, in particular selection of patients for clinical trials.
Bibliometric Analysis to Scan and Scrape New Datasets: It’s all about that BASS
Authors: Tingay Karen , Perkins Brian , Anastasiou Athanasios 
Published: April 2017

ABSTRACTObjectivesThe main objective of this poster is to present a pilot project in determining emerging population health themes and identifying key research-enabling datasets ahead of time.
At present, large-scale databanks, such as the Secure Anonymised Information Linkage (SAIL) Databank at Swansea University Medical School, already manage large quantities of health and administrative linked datasets. While these datasets are valuable for research purposes, complementary datasets may be required by collaborating researchers to answer detailed population health research questions. Dataset acquisition can take several years, which is a serious delay to a project with time-limited funding.
The ability to pre-emptively acquire datasets so that these are ready for use before a researcher requests them would obviously be beneficial. However, a recent study conducted by the Farr Cipher team at Swansea University identified over 800 health and administrative datasets in Wales alone.
With limited resources such as available funding and time, which of these datasets is worth its effort in acquiring?
ApproachBibliometrics has long been a means of measuring the impact of papers on the wider academic community. Lately, the focus of analyses has been extended to include the topics, authorship and citations of the publications. Existing bibliometric data mining techniques suggest that it is possible to identify emerging topic trends and through this assist in prioritising dataset identification and acquisition.
The project explored mining available literature through bibliometric analysis in order to predict emerging trends and through these identify potentially relevant and valuable datasets for acquisition on behalf of the Dementias Platform UK (DPUK). Literature searches were conducted for papers published on the topic of “dementia” over the last 20 years. Additional keywords and topics were extracted to identify emerging areas of research and clinical interest. These were then compared against an existing list of over 800 Welsh datasets currently not held in SAIL.
ResultsResults focus on:

Using bibliometric methods in the context of DPUK cohort publications
Identifying emerging trends in the field of dementia research.
Identifying and prioritising datasets which might be useful for the SAIL Databank to acquire

Environmental attitudes and behaviors in sustainability about water use in homes
Authors: Obeidat Islam M. , Obeidat Saif , Obeidat Manar 
Published: April 2017

Introduction: The use of water is a global environmental concern. Understanding factors affecting peoples' behavior is necessary to devise effective water management policies. Water reuse is positively influenced by environmental values, convenience, adequate storage space, simplicity of reuse, feelings of satisfaction when reusing materials, and involvement in society.
Purpose: This paper proposed and tested a conceptual framework to identify the environmental (e.g., attitude toward the environment), situational (e.g., individual knowledge and experience), and psychological (e.g., personality characteristics, perceptions) factors that affect peoples' water management intentions and behaviors in homes.
Problem: Global environmental problems (e.g., water concern) can be effectively addressed by individual lifestyle changes. Unlike reduction and reuse, recycling is not influenced by environmental values; instead, it is viewed as an accepted norm. However, access to recycling facilities or curbside recycling improves participation.
Finding: A strong relationship between intention and behavior was found for all the three water management practices (i.e., reduction, reuse, and recycling). Water reduction was positively influenced by environmental values, increased knowledge of environmental policies, the belief that water is a threat to personal well-being, and feelings of personal responsibility. Older age groups were more likely to reduce water than younger age groups, possibly because they maintained lifestyles developed during their experiences and culture. Ease of recycling (e.g., presence of curbside recycling) was associated with diminished intentions to employ water use reduction and reuse strategies, possibly because individuals who recycled felt they had fulfilled their water management responsibilities. Designers should:– enact curbside recycling methods and techniques in homes to decrease water use;– recognize how factors beyond awareness and knowledge (e.g., water values) affect water management practices;– understand that different household water management practices (i.e., reduction, reuse, and recycling) are influenced by different factors (e.g., environmental attitudes).
Multi-layer UPVC piping system
Authors: Kamal Ahmed 
Published: April 2017

Technocore is the brand name of PVC multi-layer pipes manufactured and marketed by Hepworth under the license of Wavin. Technocore is a PVC pipe made up of three layers, which improves the durability of pipes more significantly than conventional pipes with solid wall construction. The secret lies in the new and ground-breaking microcellular foaming (MCF) technology from Wavin. A uniform middle layer construction based on many small-sized cells of ≤ 50 microns ensures increased mechanical properties of the pipe combined with the inner and outer layer ‘sandwich’ construction of virgin raw material, resulting in a pipe that exceeds all the requirements for durability despite its lower weight. The Wavin multi-layer technology has been used successfully for more than 25 years. Due to modern technology, existing pipe systems can be re-engineered to comply with new requirements and continuously rising standards that enter new markets (which replace conventional materials), dedicate functionality for each individual layer, improve the characteristics of the total pipe, and achieve environmental and sustainable advantages (CSR) The cell structure of the core of the pipes reduces the weight of the pipes. Less weight means less emissions and a more sustainable future. There are other indirect environmental factors. For example, lower weight means less CO2 emissions during transport, as well as reduced CO2 consumption during recycling, reuse and disposal. A lead-free system can create a healthy working condition and protects the environment. When using new technologies, less virgin raw materials (e.g. PVC resin) are required, which make them environmental-friendly and sustainable products when compared with conventional products. All the Wavin ML-PVC products are in line with EU lead-free legislation and therefore contribute to a better HSE policy and CSR aspects. They are stimulated and supported by TEPPFA. The Wavin ML-PVC technology enables producers to participate in voluntary programs such as Vinyl-Plus (following the successful Vinyl 2000 program) Wavin and Hepworth. ML-PVC products are rated as a ‘greener’ product compared with conventional products, which enables Wavin Group and Hepworth to win tenders in many EU countries as well as in the Middle East, for example Estidama in Abu Dhabi and potentially QNBN in Doha, Qatar.
Investigation of long-term, basin-scale thermohaline trends in Qatar's marine region in response to environmental and climatic change
Authors: Husrevoglu Y. Sinan , Al-Ansari Ebrahim S. 
Published: April 2017

The Arabian Gulf, an economically and geopolitically important marine area, is a semi-enclosed and shallow basin with an average depth 36 m. The Gulf is one of the seasonally warmest (i.e., in summer) and most saline marine regions, which naturally experiences extreme seasonal heating, cooling, and evaporation cycles. Recent economic development and industrialization along with climate change also have introduced significant anthropogenic pressures on this naturally-stressed marine environment. Due to its semi-enclosed, shallow morphology and unique climatic setting, the impacts of environmental pressures are increasingly manifested in the hydrography and biogeochemistry of the Gulf. Oceanographic data collected within the exclusive economic zone (EEZ) of Qatar, although limited in space and time, indicate that physical and biogeochemical properties exhibit high spatial and temporal variability. Previous observational and numerical studies of the region conclude that increased field observation activity is required to better investigate the physical and biogeochemical dynamics of the Gulf. Long-term, continuous, and integrated monitoring of the marine environment, therefore, is essential to understand the status and seasonal/interannual variability of marine physical and biogeochemical dynamics as well as to predict any significant future changes in water column and ecological properties in response to environmental pressures and climatic changes. In this study, basin-scale oceanographic data collected in Qatar's marine region in the recent years are comparatively analyzed with available historical observations to assess thermohaline trends in water column structure and continental shelf circulation, to identify spatial and temporal data gaps, and to provide recommendations regarding optimal time and space coverage for future observational studies.

The frontier beneath our feet
Authors: Grant Gordon E. , Dietrich William E. 
Published: April 2017

AbstractFollowing the simple question as to where water goes when it rains leads to one of the most exciting frontiers in earth science: the critical zone—Earth's dynamic skin. The critical zone extends from the top of the vegetation canopy through the soil and down to fresh bedrock and the bottom of the groundwater. Only recently recognized as a distinct zone, it is challenging to study because it is hard to observe directly, and varies widely across biogeoclimatic regions. Yet new ideas, instruments, and observations are revealing surprising and sometimes paradoxical insights, underscoring the value of field campaigns and long‐term observatories. These insights bear directly on some of the most pressing societal problems today: maintaining healthy forests, sustaining streamflow during droughts, and restoring productive terrestrial and aquatic ecosystems. The critical zone is critical because it supports all terrestrial life; it is the nexus where water and carbon is cycled, vegetation (hence food) grows, soil develops, landscapes evolve, and we live. No other frontier is so close to home.

AbstractPosttransplant hepatitis C virus (HCV) recurrence is universal in chronic hepatitis C recipients. Antiviral therapy is suggested after liver transplant to halt disease progression. Pegylated interferon plus ribavirin therapy remains the standard of care in many areas where direct antiviral agents are poorly accessible. This study aimed to assess the treatment efficacy and safety of the regimen for Taiwanese patients with post‐transplant HCV recurrence. Nine patients with HCV recurrence postliver transplantation were allocated. Patients received either pegylated interferon α‐2a 180 μg/wk or pegylated interferon α‐2b 1.5 mg/kg/wk plus ribavirin for 24–48 weeks. The primary endpoint was the achievement of sustained virological response (SVR), defined as undetectable HCV RNA throughout 6 months of follow‐up after the end of treatment. The safety profiles were also documented. The rates of rapid virological response, early virological response, end‐of‐treatment virological response, and SVR were 33%, 63%, 75%, and 56% respectively. Of the four patients who failed antiviral treatment, the treatment responses were nonresponse (n = 1), loss of follow‐up (n = 1), and relapse (n = 2). Three patients terminated therapy early due to severe adverse events, including severe anemia, intra‐abdomen infection, and hepatocellular carcinoma recurrence. One of the three patients who terminated treatment early at Week 6 experienced rapid virological response followed by SVR. Pegylated interferon/ribavirin combination allowed a chance for cure with a fair SVR rate in Taiwanese chronic hepatitis C patients postliver transplantation. Early identification of side effects and careful monitoring during therapy might enhance the treatment efficacy.

Published: April 2017

Abstract
Results of comprehensive geochemical studies of dispersed organic matter of the Bazhenov Formation are presented. The maximum total contents of organic carbon are found in the areas of the Surgut arch and South Nadym megamonoclise. The contents of organic matter are high (up to 24%) at the top of the formation section and gradually decrease to its bottom. By pyrolysis parameters and the composition of hydrocarbon biomarkers, the organic matter is referred to as type II kerogen (sapropelic organic matter) and is localized in the oil window.

Published: April 2017

AbstractScrub typhus is an endemic disease of Asian Pacific region, affecting about 1 million people every year. Although it remarkably recovers with doxycycline, the mortality in untreated cases may be as high as 40 to 45%. Owing to the lack of diagnostic facilities for scrub typhus in most places, it is very important to recognize the clinical features. A typical eschar is pathognomonic of the disease. However, this is very rare to be found on the face, and hence can lead to confusions. We present the case of a boy who presented three eschars on the upper lip and was diagnosed as a case of scrub typhus. He responded dramatically with intravenous doxycycline and the eschars healed spontaneously over the next 2 to 3 weeks.
An Intramolecular CAr–H•••O=C Hydrogen Bond and the Configuration of Rotenoids
Authors: Ren Yulin , Gallucci Judith , Kinghorn A. 
Published: April 2017

AbstractOver the past half a century, the structure and configuration of the rotenoids, a group of natural products showing multiple promising bioactivities, have been established by interpretation of their NMR and electronic circular dichroism spectra and confirmed by analysis of single-crystal X-ray diffraction data. The chemical shift of the H-6′ 1H NMR resonance has been found to be an indicator of either a cis or trans C/D ring system. In the present study, four structures representing the central rings of a cis-, a trans-, a dehydro-, and an oxadehydro-rotenoid have been plotted using the Mercury program based on X-ray crystal structures reported previously, with the conformations of the C/D ring system, the local bond lengths or interatomic distances, hydrogen bond angles, and the H-6′ chemical shift of these compounds presented. It is shown for the first time that a trans-fused C/D ring system of rotenoids is preferred for the formation of a potential intramolecular C6′–H6′•••O=C4 H-bond, and that such H-bonding results in the 1H NMR resonance for H-6′ being shifted downfield.
