Australian local governments and the early national broadband network roll-out: an online survey

A recent decision by the Australian Federal Government to reassess the scale of the National Broadband Network (NBN) will leave the country with a patchwork of different levels of access to the infrastructure. This intensifies the need to investigate and evaluate the implications of telecommunication at the local level. The paper opens a discussion on the different approaches taken by local government authorities towards the NBN in the early roll-out localities. Building upon the international literature, it analyses the empirical data collected from the Australian local governments involved with the early NBN roll-out using an online survey. The findings reveal an interesting diversity in the approaches taken at the local level, and show how decision-making at higher levels of government can impact local outcomes

Executive function and autistic symptomatology in very young children

The Executive Function hypothesis proposes that the behavioural aspects of autism can be explained by impairment in executive function skills. The term 'executive function' refers to several cognitive skills including inhibitor)'control, generation of novel responses, working memory and planning. Many studies have demonstrated that school-aged children, adolescents and adults with autistic spectrum disorders are impaired on tasks designed to measure these skills (Pennington & Ozonoff, 1996). However, despite the early onset of this developmental disorder, little work has explored the executive functioning of pre-school children with autism, hi a developmental context, the executive function hypothesis would predict early executive deficits for children with autistic spectrum disorders, an association between executive function skill and symptom severity, and a relationship between the developmental trajectories of executive function and behavioural profiles. The present study recruited three-year-old children referred for autistic spectrum disorders or speech and language delay. A battery of executive function tasks measuring inhibition, working memory and planning was administered on recruitment and one year later. Detailed behavioural information was also gathered at both time points. Cross-sectional group comparisons revealed little evidence for an executive deficit in children with autism at either age. Similarly, there were no reliable relationships between executive performance and symptomatology. At a group level behavioural scores appeared to change little over the year. However, within each group there was evidence for both positive and negative change. Moreover, executive function performance did not change reliably across individuals over the year, nor was there any consistent relationship for individual children between performance on one executive function task and one behavioural domain. These findings are discussed in relation to the psychological theories of autism, and implications for intervention approaches are considered

Teledermatology to reduce face-to-face appointments in general practice during the COVID-19 pandemic : a quality improvement project

Teledermatology is an important subspecialty of telemedicine that continues to evolve with advances in telecommunication and mobile phone technology. A 19-week primary care quality improvement project collected baseline data and tested three change ideas, using the Model for Improvement method, with primary and secondary aims: to increase the weekly percentage of remote dermatological consultations with supporting images that were successfully concluded remotely to greater than 80% and to reduce the weekly percentage of dermatological face-to-face consultations to less than 50%. We hypothesised that by improving the quality of patient images and the confidence of reception staff in triaging skin complaints, there would be a decrease in the weekly number of face-to-face dermatological appointments, thereby decreasing the risk of COVID-19 transmission within the practice and community. Two change ideas focused on supporting patients to improve image quality by introducing ‘4 Key Instructions’ and a patient information leaflet (PIL). The third focused on increasing reception staff confidence in triaging skin complaints by introducing a triage pathway guidance tool. A total of 253 dermatological consultations were analysed: 170 of these were telephone consultations with 308 supporting images. Process measures showed clear improvements in the quality of images provided by patients which likely contributed to an increase in completed remote consultation. Our primary outcome measure was achieved. Our secondary outcome measure suggested that in the absence of high-quality images, it might not be possible to reduce dermatological face-to-face consultations much below 50% in primary care. Process measures showed clear improvements in the quality of images provided by patients which likely contributed to the increase in remote consultation. The implications of these findings for the theory of change are discussed.Publisher PDFPeer reviewe

MerA functions as a hypothiocyanous acid reductase and defense mechanism in Staphylococcus aureus

The major pathogen Staphylococcus aureus has to cope with host-derived oxidative stress to cause infections in humans. Here, we report that S. aureus tolerates high concentrations of hypothiocyanous acid (HOSCN), a key antimicrobial oxidant produced in the respiratory tract. We discovered that the flavoprotein disulfide reductase (FDR) MerA protects S. aureus from this oxidant by functioning as a HOSCN reductase, with its deletion sensitizing bacteria to HOSCN. Crystal structures of homodimeric MerA (2.4 Å) with a Cys43–Cys48 intramolecular disulfide, and reduced MerACys43S (1.6 Å) showed the FAD cofactor close to the active site, supporting that MerA functions as a group I FDR. MerA is controlled by the redox-sensitive repressor HypR, which we show to be oxidized to intermolecular disulfides under HOSCN stress, resulting in its inactivation and derepression of merA transcription to promote HOSCN tolerance. Our study highlights the HOSCN tolerance of S. aureus and characterizes the structure and function of MerA as a major HOSCN defense mechanism. Crippling the capacity to respond to HOSCN may be a novel strategy for treating S. aureus infections

Localization of DIR1 at the tissue, cellular and subcellular levels during Systemic Acquired Resistance in Arabidopsis using DIR1:GUS and DIR1:EGFP reporters

<p>Abstract</p> <p>Background</p> <p>Systemic Acquired Resistance (SAR) is an induced resistance response to pathogens, characterized by the translocation of a long-distance signal from induced leaves to distant tissues to prime them for increased resistance to future infection. DEFECTIVE in INDUCED RESISTANCE 1 (DIR1) has been hypothesized to chaperone a small signaling molecule to distant tissues during SAR in <it>Arabidopsis</it>.</p> <p>Results</p> <p>DIR1 promoter:DIR1-GUS/<it>dir1-1 </it>lines were constructed to examine DIR1 expression. DIR1 is expressed in seedlings, flowers and ubiquitously in untreated or mock-inoculated mature leaf cells, including phloem sieve elements and companion cells. Inoculation of leaves with SAR-inducing avirulent or virulent <it>Pseudomonas syringae </it>pv <it>tomato </it>(<it>Pst</it>) resulted in Type III Secretion System-dependent suppression of DIR1 expression in leaf cells. Transient expression of fluorescent fusion proteins in tobacco and intercellular washing fluid experiments indicated that DIR1's ER signal sequence targets it for secretion to the cell wall. However, DIR1 expressed without a signal sequence rescued the <it>dir1-1 </it>SAR defect, suggesting that a cytosolic pool of DIR1 is important for the SAR response.</p> <p>Conclusions</p> <p>Although expression of DIR1 decreases during SAR induction, the protein localizes to all living cell types of the vasculature, including companion cells and sieve elements, and therefore DIR1 is well situated to participate in long-distance signaling during SAR.</p

The Initial Economic Burden of Femur Fractures on Informal Caregivers in Dar es Salaam, Tanzania

BackgroundFemur fracture patients require significant in-hospital care. The burden incurred by caregivers of such patients amplifies the direct costs of these injuries and remains unquantified. Aim Here we aim to establish the in-hospital economic burden faced by informal caregivers of femur fracture patients. Methods 70 unique caregivers for 46 femoral shaft fracture patients were interviewed. Incurred economic burden was determined by the Human Capital Approach, using standardized income data to quantify productivity loss (in $USD). Linear regression assessed the relationship between caregiver burden and patient time-in-hospital.ResultsThe average economic burden incurred was$149, 9% of a caregiver’s annual income and positively correlated with patient time in hospital (p&lt;0.01). Conclusion Caregivers of patients treated operatively for femur fractures lost a large portion of their annual income, and this loss increased with patient time in hospital. These indirect costs of femur fracture treatment constitute an important component of the total injury burden

Gambling harms in adult social care: developing an ‘introductory’ question to identify gambling harms among service users

Gambling harms are disproportionately experienced among disadvantaged groups and as such, adult social care (ASC) practitioners are well-placed to identify and support affected individuals. There exists no evidence-based ‘introductory’ question for practitioners to identify those at risk of gambling harms, which includes family and friends (‘affected others’). To develop an ‘introductory’ question for use in English ASC, we conducted a scoping review that identified fifteen potential questions. Questions were refined through expert panel review groups (n = 13), cognitive interviewing (n = 18), test–retest reliability checks (n = 20) and validity testing (n = 2,100) against gold-standard measures of problem gambling behaviour. The question development process produced two questions suitable for testing in local authority (LA) ASC departments. These were (i) ‘Do you feel you are affected by any gambling, either your own or someone else’s?’ and (ii) ‘If you or someone close to you gambles, do you feel it is causing you any worries?’ Each had good face validity, strong test–retest reliability, correlated highly with well-being measures and performed reasonably against validated measures of problem gambling. These two questions are currently being piloted by ASC practitioners in three English LAs to assess their feasibility for adoption in practice

Bringing plant-based veterinary vaccines to market: Managing regulatory and commercial hurdles

AbstractThe production of recombinant vaccines in plants may help to reduce the burden of veterinary diseases, which cause major economic losses and in some cases can affect human health. While there is abundant research in this area, a knowledge gap exists between the ability to create and evaluate plant-based products in the laboratory, and the ability to take these products on a path to commercialization. The current report, arising from a workshop sponsored by an Organisation for Economic Co-operation and Development (OECD) Co-operative Research Programme, addresses this gap by providing guidance in planning for the commercialization of plant-made vaccines for animal use. It includes relevant information on developing business plans, assessing market opportunities, manufacturing scale-up, financing, protecting and using intellectual property, and regulatory approval with a focus on Canadian regulations

The Effectiveness of Passive Physical Modalities for the Management of Soft Tissue Injuries and Neuropathies of the Wrist and Hand: A Systematic Review by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration

AbstractObjectiveThe purpose of this systematic review was to determine the effectiveness of passive physical modalities compared to other interventions, placebo/sham interventions, or no intervention in improving self-rated recovery, functional recovery, clinical outcomes and/or administrative outcomes (eg, time of disability benefits) in adults and/or children with soft tissue injuries and neuropathies of the wrist and hand.MethodsWe systematically searched MEDLINE, EMBASE, PsycINFO, and the Cochrane Central Register of Controlled Trials, accessed through Ovid Technologies, Inc, and CINAHL Plus with Full Text, accessed through EBSCO host, from 1990 to 2015. Our search strategies combined controlled vocabulary relevant to each database (eg, MeSH for MEDLINE) and text words relevant to our research question and the inclusion criteria. Randomized controlled trials, cohort studies, and case-control studies were eligible. Random pairs of independent reviewers screened studies for relevance and critically appraised relevant studies using the Scottish Intercollegiate Guidelines Network criteria. Studies with low risk of bias were synthesized following best evidence synthesis principles.ResultsWe screened 6618 articles and critically appraised 11 studies. Of those, 7 had low risk of bias: 5 addressed carpal tunnel syndrome (CTS) and 2 addressed de Quervain disease. We found evidence that various types of night splints lead to similar outcomes for the management of CTS. The evidence suggests that a night wrist splint is less effective than surgery in the short term but not in the long term. Furthermore, a night wrist splint and needle electroacupuncture lead to similar outcomes immediately postintervention. Finally, low-level laser therapy and placebo low-level laser therapy lead to similar outcomes. The evidence suggests that kinesio tape or a thumb spica cast offers short-term benefit for the management of de Quervain disease. Our search did not identify any low risk of bias studies examining the effectiveness of passive physical modalities for the management of other soft tissue injuries or neuropathies of the wrist and hand.ConclusionsDifferent night orthoses provided similar outcomes for CTS. Night orthoses offer similar outcomes to electroacupuncture but are less effective than surgery in the short term. This review suggests that kinesio tape or a thumb spica cast may offer short-term benefit for the management of de Quervain disease
