Abstract: The consequences of cancer and treatment on fertility can be a continuing source of distress for adolescents and young adults. The study aims were to assess the effects of bundled interventions on clinical practice concerning fertility in young people aged 14-25 years with cancer. Bundled interventions, including development of quality indicators, resources, and targeted education, were introduced during 2015 across five cancer centers. Data before interventions (2012-2014) were compared with data prospectively collected during 2015-2016. Relative risks (RR) with 95% confidence intervals (CI) were calculated to assess effects of interventions. Compared with the pre-intervention cohort (n = 260), the post-intervention cohort (n = 216) was 1.47 times more likely to have documented discussion of risk of infertility (95% CI 1.12-1.63, p = <0.001). Similarly, documented referral to fertility specialists was more likely in the post-intervention cohort (RR 1.53, 95% CI 1.26-1.87, p = <0.001) as was documented fertility preservation outcomes (RR 2.56, 95% CI 1.91-3.44, p = <0.001). These differences were significant across age, gender, and diseases. Females had greater improvement in documented risk of infertility discussion between cohorts (RR 1.70, 95% CI 1.19-2.08, p = <0.001). Among diseases, the greatest improvements were seen in those with brain cancers (RR 2.15, 95% CI 1.28-3.62, p = 0.004) and soft tissue sarcoma (RR 2.60, 95% CI 1.17-5.78, p = 0.02). We have demonstrated the effects of bundled interventions to improve clinical practice associated with fertility preservation in young people with cancer. Interventions were successful for reducing disparities identified in the pre-intervention cohort associated with gender and certain diseases. Assessment of the quality of patient care is not possible without accurate, consistent documentation.

Abstract: A massive amount of data is generated with the evolution of modern technologies. This high-throughput data generation results in Big Data, which consist of many features (attributes). However, irrelevant features may degrade the classification performance of machine learning (ML) algorithms. Feature selection (FS) is a technique used to select a subset of relevant features that represent the dataset. Evolutionary algorithms (EAs) are widely used search strategies in this domain. A variant of EAs, called cooperative co-evolution (CC), which uses a ide-and-conquer approach, is a good choice for optimization problems. The existing solutions have poor performance because of some limitations, such as not considering feature interactions, dealing with only an even number of features, and decomposing the dataset statically. In this paper, a novel random feature grouping (RFG) has been introduced with its three variants to dynamically decompose Big Data datasets and to ensure the probability of grouping interacting features into the same subcomponent. RFG can be used in CC-based FS processes, hence called Cooperative Co-Evolutionary-Based Feature Selection with Random Feature Grouping (CCFSRFG) . Experiment analysis was performed using six widely used ML classifiers on seven different datasets from the UCI ML repository and Princeton University Genomics repository with and without FS. The experimental results indicate that in most cases [i.e., with naïve Bayes (NB), support vector machine (SVM), k -Nearest Neighbor ( k -NN), J48, and random forest (RF)] the proposed CCFSRFG-1 outperforms an existing solution (a CC-based FS, called CCEAFS) and CCFSRFG-2, and also when using all features in terms of accuracy, sensitivity, and specificity.

Abstract: The Oncology Family App supports families across the vast state of Queensland, Australia, with easy access to vital information, including management plans for a deteriorating child, patient specific information and other resources. This article describes the development and evaluation of this mobile app. The app was developed and tested in collaboration with parents, caregivers, and clinicians and released in November 2015. This first version featured “Statewide Hospital Contacts,” including phone numbers, links to Google maps, and 24-hour emergency contacts with click to call functionality “When to Call” describing symptoms to look out for in a deteriorating child “Blood Results Table” and “Information” listing recommended websites, health care team contacts, appointments, and notes. The app was evaluated through interviews with parents, caregivers and patients and download metrics. Six months after the app release, 68% of the 38 parents and caregivers surveyed had downloaded the app. The most used modules were “Blood Results Table,” “When to Call,” and “Statewide Hospital Contacts,” but families reported using all features available. Families were enthusiastic about the support the app provided and gave useful feedback to direct future development. Using mobile health technology to support families is a novel, but rapidly growing concept. Family and caregiver feedback showed that the Oncology Family App was an efficient and convenient way to provide much needed information. A new version of the app is under development and evaluation of outcomes will be ongoing.

Abstract: A retrospective analysis of hospitalisation due to oral and dental conditions (ODC) was performed for patients in Queensland. The aim was to identify the rate and cost of hospitalisation and to examine the association between hospitalisation and age, geographical location and Indigenous status. There were 81528 admissions to Queensland’s hospitals due to ODC during the 3-year study period (2011–2013). The annual cost of ODC-related hospitalisation was estimated to be AU$87million. Indigenous infants (Z=4.08, P .001) and primary school children (Z=2.01, P=0.046) were significantly more likely to be hospitalised than their non-Indigenous counterparts. A non-Indigenous high school child was almost fourfold more likely to be hospitalised. There was no significant difference in the rate of hospitalisation for adults. Infants (Z=6.70, P .001) and primary school children (Z=8.73, P .001) from remote areas were significantly more likely to be hospitalised than their age-matched metropolitan counterparts. Whereas high school children (Z=2.74, P=0.006) and adults (Z=6.02, P .001) from remote areas were significantly less likely to be hospitalised. Our findings suggest that there is a need for alternative models of primary dental care to service remote areas of Queensland and Indigenous populations. Strategies that enable Indigenous Health Workers to provide dental care, and the use of teledentistry, are models of care that may reduce potentially preventable hospitalisations and lead to cost savings and better health outcomes.

Abstract: To examine reported outcomes of health services delivered by telehealth to Indigenous Australians. Systematic review of the literature. Searches were conducted to identify articles that reported a telehealth service used to provide clinical services to Indigenous Australians. Articles were screened for inclusion using pre-defined criteria. Findings were synthesised narratively and reported using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. 14 articles, describing 11 distinct telehealth services, were selected based on the inclusion criteria. Authors of included studies report that telehealth has improved social and emotional wellbeing, clinical outcomes and access to health services for Indigenous Australians. Further, it has reduced travel and improved screening rates. Indigenous people report positive perceptions of their telehealth interaction. Telehealth is used to address poor accessibility to health services and for targeted screening programs for at risk populations. Reported outcomes from existing services demonstrate the potential of telehealth for health service delivery for Indigenous Australians. Confidence in the findings of this review is reduced by the predominance of descriptive studies and small s le sizes in many of the included articles. Telehealth models of care facilitated through partnerships between Aboriginal community-controlled health services and public hospitals may improve both patient outcomes and access to specialist services for Indigenous people.

Abstract: The present study evaluates the effect of Camellia sinensis leaves (CSL) extract on the corrosion inhibition of carbon steel in produced water using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and computational methods. The chromatographic investigation of the extract was performed by HPLC. It was found that CSL extract serves as a mixed-type corrosion inhibitor and its inhibitive performance increases with concentration. The corrosion inhibition was assumed to occur via adsorption of the primary constituents of CSL extract. Surface analysis (SEM and FTIR) was also carried out to establish the mechanism of corrosion inhibition. The outcomes obtained from the computational study were found to confirm experimental data.

Abstract: Providing equitable access to healthcare services in rural and remote communities is an ongoing challenge that faces most governments. By increasing access to specialty expertise, telemedicine may be a potential solution to this problem. Regardless of its potential, many telemedicine initiatives do not progress beyond the research phase, and are not implemented into mainstream practice. One reason may be that some telemedicine services are developed without the appropriate planning to ascertain community needs and clinical requirements. The aim of this paper is to report the development of a planning framework for telemedicine services based on needs assessment. The presented framework is based on the key processes in needs assessment, Penchansky and Thomas's dimensions of access, and Bradshaw's types of need. This proposed planning framework consists of two phases. Phase one comprises data collection and needs assessment, and includes assessment of availability and expressed needs accessibility perception and affordability. Phase two involves prioritising the demand for health services, balanced against the known limitations of supply, and the implementation of an appropriate telemedicine service that reflects and meets the needs of the community. Using a structured framework for the planning of telemedicine services, based on need assessment, may help with the identification and prioritisation of community health needs.

Abstract: The adoption of telemedicine into mainstream health services has been slower than expected. Many telemedicine projects tend not to progress beyond the trial phase there are a large number of pilot or project publications and fewer 'service' publications. This issue has been noted since 1999 and continues to be acknowledged in the literature. While overall telemedicine uptake has been slow, some services have been successful. The reporting and evaluation of these successful services may help to improve future uptake and sustainability. The aim of this literature review was to identify peer-reviewed publications of deployed telemedicine services in hospital facilities and to report, and appraise, the methodology used to evaluate these services. Computerised literature searches of bibliographic databases were performed using the MeSH terms for "Telemedicine" and "Hospital Services" or "Hospital", for papers published up to May 2016. A total of 164 papers were identified, representing 137 telemedicine services. The majority of reported telemedicine services were based in the United States of America (n=61, 44.5%). Almost two thirds of the services (n=86, 62.7%) were delivered by real time telemedicine. Of the reviewed studies, almost half (n=81, 49.3%) assessed their services from three different evaluation perspectives: clinical outcomes, economics and satisfaction. While the remaining half (n=83, 50.6%) described their service and its activities without reporting any evaluation measures. Only 30 (18.2%) studies indicated a two-step implementation and evaluation process. There was limited information in all reported studies regarding description of a structured planning strategy. Our systematic review identified only 137 telemedicine services. This suggests either telemedicine service implementation is still not a part of mainstream clinical services, or it is not being reported in the peer-reviewed literature. The depth and the quality of information were variable across studies, reducing the generalisability. The reporting of service implementation and planning strategies should be encouraged. Given the fast paced technology driven environment of telemedicine, this may enable others to learn and understand how to implement sustainable services. The key component of planning was underreported in these studies. Studies applying and reporting more rigorous methodology would contribute greatly to the evidence for telemedicine.
