Custodian Controlled Data Repository - supporting the timely, easy and cost effective access to linked data
Authors: Radbone Christopher , Adams Suzi 
Published: April 2017

ABSTRACTObjectivesIn response to Data Custodian and Researcher's request to assist improving the timeliness and ease of data extractions, SA NT DataLink established the Custodian Controlled Data Repository (CCDR). Issues including conflicting work priorities and limited resources do prevent timely data extractions. SA NT DataLink, as a trusted third party enable Custodians to hold separate copies of their de-identified content data ready for timely release. The CCDR is opt-in for Custodians. Its key strength being the data remains under the control of participating Custodians, with Custodians updating and correcting their data. SA NT DataLink staff are work with Data Custodians to clean, standardise, update and prepare data in advance of anticipated approvals, including spatial enabled GIS variables. SA NT DataLink staff work under the direction of the Data Custodians, taking responsibility for preparing the data extractions required for the approved project.
ApproachThe SA NT DataLink Custodian Controlled Data Repository (CCDR) takes advantage of the Secure Unified Research Environment (SURE), which is a secure remote access data laboratory operated by the Sax Institute in Sydney Australia. Using thin client and two-factor authentication, Data Custodians from South Australia and across Australia are able to securely store and maintain de-identified copies of their content data in SURE, ready for standardisation, quality review, and more timely release for approved use and data linkage projects.
ResultsThe CCDR functional diagram provides an understanding of the data flow and processes that support more timely, easy and cost effective collation and provision of de-identified and privacy protected data. The Curated Gateway feature of SURE manages all the data coming into and being released from the Repository. Agreed regular updates of Data Custodian's data is able to be stored into their sub-directory, with access to the sub-directory managed by authentication and passwords. The SA NT DataLink Analysts is able to perform the role of data integrator for approved projects and use, also running privacy protecting algorithms and verification of the data being provided against the approvals.
ConclusionThe CCDR securely stores the de-identified data ready for it to be integrated and released to Researchers. Use of secure remote access technologies allows Data Custodians to maintain control of their preloaded and pre-cleaned data in CCDR. In doing so this allows Custodians to authorise the use, from which SA NT DataLink staff dedicated to working only in the CCDR, integrate and release the data in a more timely manner.
Suicide Prevention through Shared Information
Authors: Balbuena Lloyd , Bowen Rudy , Baetz Marilyn 
Published: April 2017

ABSTRACT
ObjectivesAlthough mental health clinicians are in the best position to assess a person’s risk for suicide, people at imminent risk may first seek the help of crisis workers, the police, hospital staff, or family members. The present project will use international (UK Biobank), provincial, and local crisis line data to elucidate imminent risks for suicide. An interdisciplinary team will discuss whether a common protocol for handling acute cases is warranted. The possibility of sharing a minimal set of information across services will also be discussed.
ApproachThe conceptual framework is that suicide is a probabilistic outcome of risks (comprised of inherited traits, habits, and environmental stressors) that can be put in temporal order as distal, proximate, and immediate antecedents. Local, provincial, and international data will be mined for risks corresponding to each epoch. The evidence will be assessed by an interdisciplinary team composed of patient advocates, psychiatrists, the police service, community health workers and academic researchers with the objective of reaching an agreement on a common protocol for suicidality assessment. The possibility of sharing a minimal dataset that is relevant to saving the lives of people at imminent risk of suicide will be explored. Finally, the efficacy of coordinated care across services will be evaluated by comparing suicide and self-harm rates will be assessed by comparing suicide and self-harm rates before and after the adoption of the protocol.
ResultsAn interdisciplinary team has been formed and funding for the project is being sought. An application for data access to the UK Biobank received preliminary approval and is being evaluated by the scientific committee. Applications for access to provincial administrative data as well as telephone crisis line data for the last 10 years are being prepared.
ConclusionRoutinely collected administrative data is a resource for the collective decision-making of an interdisciplinary team of experts and patient advocates. The ability of critical information to flow across organizational boundaries may be an important tool in suicide prevention. Dialogues regarding the ethical dilemma between potentially saving lives and potentially breaking privacy may need to happen.
The Yin & Yang of Data Management - Four intractable contradictions and their harmonious resolutions
Authors: Hacker Alex 
Published: April 2017

ABSTRACT
ObjectivesIn our long-term prospective cohort study of over 500,000 adults, participants are actively followed-up through established morbidity and mortality registries, and by linkage to the national health insurance system. We also administer regular questionnaires; take physical measurements; and gather genetic, metabolomics, and even meteorological data.
Importing, integrating and distributing such a large and diverse dataset presents practical challenges, but also more fundamental ones. When individually reasonable data management requirements come into conflict, can a solution be found that satisfies both without compromising either? In this session I present, with examples, four such conflicts and the ways in which we harmonise and resolve them.
Approach & ResultsGather perfect data / Handle imperfect dataA data manager does not want to allow erroneous data into their database, but nor do they want to discard data that are imperfect but still meaningful. The approach that we take is to implement automatic validation at the point of entry, tailored to the data source in question.
Fix data issues / Don't make assumptionsIdeally every data issue that is detected should be fixed or flagged, but correction is not always possible and it's rarely clear where to draw the line between error and outlier. We address this via comprehensive data documentation, empowering each analyst to identify, assess and handle the values that might be problematic for them.
Be flexible / Be consistentEvery researcher has different data requirements, definitions and exclusions. Data management must support this without needless duplication of effort, or leaving everyone working on incompatible datasets. Our solution is centralised distribution: a single core database, centrally maintained and updated, from which all analyst's datasets are derived, and into which the work of individuals is incorporated for the benefit of all.
Keep it simple / Include everythingMost analyses examine some areas of the data in great detail but require only basic summaries of others. We supports this using well-chosen data aggregation, offering multiple levels of detail so that each analyst can decide how far they wish to ‘zoom in’ on each element.
ConclusionSome apparently contradictory requirements of data management can be resolved with the above techniques, creating a resource suitable for a wide range of applications without compromise.

Published: April 2017

ABSTRACT
ObjectivesIdentify geographic variations in health and healthcare among US Veterans living in rural areas and understand the relationships between social determinants of health and these variations.
ApproachData from 11 data sources will be leveraged to create the US Veterans Rural Health Atlas and chart book (VeRHA) patterned after the Dartmouth Atlas, The VeHRA will provide an interactive map and chart book can be used to efficiently examine a wide range of factors related to health and healthcare of rural Veterans. The analyses will assess the relationships between socioeconomic, cultural and environmental factors and geographical variation in access, utilization, quality, satisfaction and outcomes. Semi-structured qualitative interviews will be used to elicit the perspective of Veterans not using VA care and to identify non-governmental organizations who provide care and support to US Veterans. The project will also identify community, state, and federal entities with which ORH could form strategic partnerships to improve health and healthcare for Rural Veterans.
Initially, three maps will be created for Veterans who are not enrolled in care, those enrolled but not using care and those enrolled and using care. Areas where many Veterans live and use VA healthcare will be identified as “hot spots” while areas where Veterans live but do not use care will be identified as “cold spots”. Metrics for determining “hot and cold spots” will include measures of temporal and geographic access as well as measures of quality of care. We will first calculate raw rates for outcomes across geographic areas (census tract, county, and market/regions) Exploratory Spatial Data Analysis (ESDA) will be conducted by mapping the geographic distribution of key measures and then calculate the values of the local and global Moran’s I measures of spatial autocorrelation.
The relationship between social determinants of health and geographical variation in access, needs, utilization, quality, satisfaction, and outcomes for rural Veterans will be assessed, focused primarily on the “cold spots” – areas of greatest need.
ResultsThe project is a work in progress with initial maps created showing the density of Veterans across the United States. More extensive results will be available for presentation.
ConclusionThis work demonstrates the value of using large data sets to guide development of policies and programs at a national level.

Published: April 2017

ABSTRACTObjectivesThere have been a number of key changes in the clinical definition and diagnostic threshold of acute coronary syndromes in the last 10 years. We have characterised temporal and geographic changes in the incidence and outcomes following Acute Coronary Syndrome (ACS: Unstable Angina (UA), Non ST-segment elevation myocardial infarction (NSTEMI) and ST-segment elevation myocardial infarction (STEMI)) between 2009 and 2013.
Approach65,137 hospitals stays were identified involving ACS (ICD-10: I20.0, I21 and I22) relating to 55,369 individuals identified through secondary care primary diagnosis records during 2009-2013. All prior and subsequent secondary care diagnoses from 1981-2014 were sourced for these patients and records were deterministically matched on a pseudo patient identifier to obtain the cause and date of death for purposes of follow-up. An incident ACS case was defined as such if the patient had not suffered an ACS in the five years prior to the hospital admission and all co-morbidities were derived from hospital diagnostic codes accompanying the ACS codes.
ResultsFor the entire cohort, patients with an incident ACS were predominantly male (61.5%) with mean age 68 (SD=13.7 years). Co-morbidities included: 65.5% Other Ischaemic Heart Disease; 5.2% Stroke; 7.5% Peripheral Artery Disease; 14.8% Atrial Fibrillation; 42.0% Hypertension; 18.0% Diabetes Mellitus and 8.4% Chronic Kidney Disease.
The overall incidence of ACS in 2009 was 204/100,000 and fell by 8.1% to 188/100,000 in 2013. Subtypes of ACS comprised 9.4% UA, 50.9% NSTEMI, 29.0% STEMI and 10.8% MI unspecified in 2013.
In-hospital mortality following an incident ACS was 9.7% (95% CI: 9.2-10.3%) in 2009 and varied from 7.9 to 19.0% across the NHS boards. In 2013, in-hospital mortality was 8.5% (95% CI: 7.9-9.0%) ranging from 4.5 to 10.5% across the NHS boards. One-year mortality following an incident ACS in 2009 was 18.6% (95% CI: 17.9-19.4%) falling to 16.8% (95% CI: 16.1-17.5%) in 2013. Stratified by NHS board, the one-year mortality rate in 2009 varied from 16.9 to 28.0% and in 2013 ranged from 11.9 to 20.0% across the NHS boards.
ConclusionThese findings highlight the importance of a cohort based record linkage approach to routine healthcare datasets. While there appears to be changes in incidence of ACS and its subtypes and changes in mortality over time, these findings reflect significant changes in clinical practice with respect to definition and diagnosis. Cautious interpretation is needed combined with further research to fully understand the epidemiological implications of our findings.
Trends in Place of Death in Children who died after discharge from Paediatric Intensive Care Units : A national data linkage study
Authors: Fraser Lorna , Fleming Sarah , Parslow Roger 
Published: April 2017

ABSTRACT
AimTo identify characteristics of children who died in the community rather than hospital.
MethodsAll children admitted to a PICU in England or Wales (1st Jan 2004 and 31st Dec 2014) were identified in the PICANet dataset. Linkage to death certificate data was available up to the end of 2014.Place of death was categorised as hospital (hospital or PICU) or community (hospice, home or other) for multivariable logistic modelling.
ResultsThe cohort consisted of 110,328 individuals. 4760 deaths occurred on first admission in PICU (excluded from analyses) and 7709 deaths occurred after first discharge from PICU. Overall 41.2% of these deaths occurred in hospital, 32.5% in PICU, 16.6% at home, 8.7% in hospice and 0.7% elsewhere. Deaths in hospital (incl PICU) decreased from more 83.8% in 2004 to 68.1% in 2014. 852 (0.8%) of children were discharged to palliative care.Children discharged to palliative care were 8.4 times more likely to die in the community (OR 8.36 95%CI (6.76-10.34)). Children in all older age groups were significantly more likely to die outside hospital than the under 1s.Children from a South Asian background (OR 0.48 95%CI (0.36-0.58)) and those living in the most deprived categories were significantly less likely to die outside the hospital.
ConclusionsA large proportion of children dying after discharge from PICU continue to die in hospital. More involvement of palliative care at the point of discharge has the potential to offer choice around place of care and death for these children and families.

Dynamics (seasonal and intra-diurnal) of air-borne fungal spore population of Doha area, Qatar
Authors: Fayad Raghda K. , Abu-Dieyeh Mohammed H. 
Published: April 2017

The availability and dynamics of airborne fungal spores in the atmosphere are strongly influenced by the meteorological parameters and by other factors such as air pollutants. The aim of this study was to update the knowledge about the seasonal and diurnal variations in airborne fungal spores of Doha area and to correlate these variations with meteorological factors, and to investigate the influence of atmospheric CO2 concentrations and different culture media on the availability of fungal spores. From 106 settle plate exposures (on alternative days) throughout the period April 2015-March 2016, a total of 1197 mould- and 283 yeast colony-forming units (CFU), twenty one genera and 62 species were retrieved. The highest fungal spore's concentration was recorded in February 2016, whereas the lowest concentration occurred in August 2015. The main constituents of the fungal airspora were attributed to Cladosporium (60.2%), Aspergillus (10.4%), Fusarium (9.4%), Alternaria (8.5%), and Ganoderma spp. (2.3%). Cladosporium showed two peaks in April and February, while Fusarium and Alteranria peaked in July. Aspirgillus had one peak in August. The prevalence of Ganoderma spp. were exclusively detected in February and March. Temperature was significantly and negatively correlated with the total colony count and fungal species, however no significant correlation was found between relative humidity and both the total colony count and fungal species. Wind speed was significantly and positively correlated with the total colony count and fungal species. The correlation between rainfalls and either total colony count or fungal species was non-significant. Intra-diurnal fluctuations of fungal spores was investigated during the period of 1st of Feb – 31st of March 2016. The highest dispersal of fungal spores favored 18:00 h, whereas at 00:00 h (midnight) the lowest fungal spores release was recorded. No significant difference was observed in total number of fungal colonies or species collected with the two media Potato Dextrose Agar (PDA) and Rose Bengal media. Nevertheless, certain fungal taxa were highly selective and thus their growth rate was on one media much higher than with another. There were no significant differences in the composition and diversity of the airborne fungal population between two different study sites under the influence of atmospheric CO2 concentration, though daily concentration of CO2 was higher at the Industrial area site than at Qatar University Campus. Remarkably, the concentrations of Alternaria spp. and Fusarium spp. were significantly higher at Industrial area site in corresponding to CO2 than at Qatar University site.

Published: April 2017

This study aimed to establish a new protocol for in vitro rooting and acclimatization of date palm (Phoenix dactylifera L.) in different cultivars “Shishi and Lulu”. In order to increase growth and achieve a higher survival rate of plantlets through the acclimatization stage. The plantlets of the two cultivars were cultured in media in three successive steps (each of 6 weeks). In First and second steps kinetin and malt extract were tested to optimize the quality of plantlets in the presence of α-Naphthalene acetic acid (NAA). Third step were cultured plantlets onto liquid media with poly ethylene glycol. The obtained results showed that, plantlets grown on malt extract at 750 mg/l had wider and greener leaves 0.81, 0.74 mm and encouraged the adventitious roots number per plantlet 6.88, 6.10 in Shishi and lulu cultivars. Results demonstrated that the new established protocol is efficient in acclamation date palm. The highest survival rate was 98.66, 87.66 % of two cultivars at the acclimatization stage within a short period (3 month).
Global change impacts: How QNRF addresses those key scientific and societal issues
Authors: Freyssinet Philippe 
Published: April 2017

Climate change, and more generally Global Change issues have become a major field of environmental research for now more than 20 years. It is also an important component of the Qatar National Research Strategy. Qatar is already strongly committed to develop a more sustainable economy and diversified economy, as clearly stated in the National 2030 Vision.A large part of QNRF initiatives are aligned with those goals, as about 30 to 40% of the awarded projects by QNRF are dealing with sustainability topics. This covers in particular environmental issues, sustainable construction, low carbon energy technologies, renewable energies, risks related to regional climate change, CO2 emissions abatement technologies. QNRF addresses those scientific issues through its main collaborative research program NPRP, but also joined recently the Belmont Forum, a network of 25 funding agencies worldwide to support international calls on Global Change research.Climate change may induces many changes on the environment in the Gulf region in the forthcoming decades. Those changes may induce ecological risks, but also risks for the health population and the infrastructures. How important are these risks? Do they cumulate?If Global climate change scenarios are consistent, there is still a lot of uncertainty about climate change scenarios in the Gulf region, compared to other regions which are well documented such as the Mediterranean region or Northern Europe. Modeling of climate change at regional scale is a key issue to better define decadal trends, prevent extreme events or the impact on marine life.On another hand, R&D priority themes also focus on strengthening the national expertise to support the definition of mitigation strategies at governmental level.
