AIM: Chromosomal microarray (CMA) is an important diagnostic test for children with multiple congenital anomalies or certain developmental behavioural problems suggestive of an underlying genetic diagnosis. However, there are medical and ethical complexities to its use and few Australian policies to guide practice. We aimed to describe the current practice of Australian paediatricians in relation to CMA testing. We hypothesised that there are knowledge gaps in their use of CMA. METHODS: Online survey completed between September 2015 and January 2016 by paediatricians in secondary care settings...

AIM(S): Newly graduated doctors write a large proportion of prescriptions in UK hospitals but recent studies have shown that they frequently make prescribing errors. The Prescribing Safety Assessment (PSA) has been developed as an assessment of competence in relation to prescribing and supervising the use of medicines. This report describes the delivery of the PSA to all UK final-year medical students in 2016 (PSA2016). METHODS: The PSA is a 2-hour online assessment comprising eight sections which cover various aspects of prescribing defined within the outcomes of undergraduate education identified by the UK General Medical Council...

Skin cancer is a major public health concern in Australia and around the world, and UV radiation exposure is accepted as the most readily modifiable risk factor for the disease(1) . The attitudes and behaviours of young adults towards sun protection play an important role in their future risk of skin cancer, and are thus an important target for sun-safety messaging. A cross-sectional study aiming to investigate the sun-protective behaviours and attitudes of Australian medical students during both everyday outdoor activities and while travelling for leisure was conducted via an online questionnaire...

Motivation: Epigenetic data are invaluable when determining the regulatory programs governing a cell. Based on use of next-generation sequencing data for characterizing epigenetic marks and transcription factor binding, numerous peak-calling approaches have been developed to determine sites of genomic significance in these data. Such analyses can produce a large number of false positive predictions, suggesting that sites supported by multiple algorithms provide a stronger foundation for inferring and characterizing regulatory programs associated with the epigenetic data...

Motivation: Biological data and knowledge bases increasingly rely on Semantic Web technologies and the use of knowledge graphs for data integration, retrieval and federated queries. In the past years, feature learning methods that are applicable to graph-structured data are becoming available, but have not yet widely been applied and evaluated on structured biological knowledge. Results: We develop a novel method for feature learning on biological knowledge graphs...

Motivation: Genetic loci associated with the variance of phenotypic traits have been of recent interest as they can be signatures of genetic interactions, gene by environment interactions, parent of origin effects and canalisation. We present a fast efficient tool to map loci affecting variance of gene expression and other molecular phenotypes in cis. Results: Applied to the publicly available Geuvadis gene expression dataset, we identify 816 loci associated with variance of gene expression using an additive model, and 32 showing differences in variance between homozygous and heterozygous alleles, signatures of parent of origin effects...

Motivation: Realizing the value of synthetic biology in biotechnology and medicine requires the design of molecules with specialized functions. Due to its close structure to function relationship, and the availability of good structure prediction methods and energy models, RNA is perfectly suited to be synthetically engineered with predefined properties. However, currently available RNA design tools cannot be easily adapted to accommodate new design specifications. Furthermore, complicated sampling and optimization methods are often developed to suit a specific RNA design goal, adding to their inflexibility...

BACKGROUND: Several microRNA (miRNA) molecules have emerged as important post-transcriptional regulators of tumour suppressor and oncogene expression. Ras association domain family member 1 (RASSF1) is a critical tumour suppressor that controls multiple aspects of cell proliferation such as cell cycle, cell division and apoptosis. The expression of RASSF1 is lost in a variety of cancers due to the promoter hypermethylation. METHODS: miR-193a-3p was identified as a RASSF1-targeting miRNA by a dual screening approach...

BACKGROUND: The microvascular contrast agent transfer constant K(trans) has shown prognostic value in cervical cancer patients treated with chemoradiotherapy. This study aims to determine whether this is explained by the contribution to K(trans) of plasma flow (Fp), vessel permeability surface-area product (PS), or a combination of both. METHODS: Pre-treatment dynamic contrast-enhanced MRI (DCE-MRI) data from 36 patients were analysed using the two-compartment exchange model...

BACKGROUND: Mutations in the KRAS gene can be detected in about 70-90% of pancreatic cancer (PC) cases. Whether these mutations have a prognostic or predictive value remains elusive. Furthermore, the clinical relevance of the extended RAS (KRAS+NRAS) mutational status is unclear in PC. METHODS: We prospectively defined a PC patient population who received erlotinib-free chemotherapy regimens. A statistically significant difference between KRAS wild-type and KRAS mutated tumours in at least 160 patients in this population would support the assumption of a rather prognostic role of KRAS...

BACKGROUND: Pathological extramural vascular invasion (EMVI) is an independent prognostic factor in rectal cancer, but can also be identified on MRI-detected extramural vascular invasion (mrEMVI). We perform a meta-analysis to determine the risk of metastatic disease at presentation and after surgery in mrEMVI-positive patients compared with negative tumours. METHODS: Electronic databases were searched from January 1980 to March 2016. Conventional meta-analytical techniques were used to provide a summative outcome...

Received-signal-strength-based (RSS-based) device-free localization (DFL) is a promising technique since it is able to localize the person without attaching any electronic device. This technology requires measuring the RSS of all links in the network constituted by several radio frequency (RF) sensors. It is an energy-intensive task, especially when the RF sensors work in traditional work mode, in which the sensors directly send raw RSS measurements of all links to a base station (BS). The traditional work mode is unfavorable for the power constrained RF sensors because the amount of data delivery increases dramatically as the number of sensors grows...

Gangyong Jia, Guangjie Han, Hao Wang, Xuan Yang
In a cloud computing environment, the number of virtual machines (VMs) on a single physical server and the number of applications running on each VM are continuously growing. This has led to an enormous increase in the demand of memory capacity and subsequent increase in the energy consumption in the cloud. Lack of enough memory has become a major bottleneck for scalability and performance of virtualization interfaces in cloud computing. To address this problem, memory deduplication techniques which reduce memory demand through page sharing are being adopted...

Jennifer Loh, Craig Harms, Bronwyn Harman
BACKGROUND: Parental stress, optimism, and health-promoting behaviors (HPBs) are important predictors of the quality of life (QoL) of mothers. However, it is unclear how strongly these predictors affect the QoL of mothers. It is also unclear if the impact of these predictors on QoL differs between primiparous and multiparous mothers. In this study, we defined primiparous as "bearing young for the first time" and multiparous as "having experienced one or more previous childbirths." OBJECTIVES: The first objective of this study was to examine the relative effect of parental stress, optimism, and HPBs on the QoL of mothers...
