Published: September 2019

AbstractCoccidioides immitis is an emerging fungal pathogen in Washington State (WA). While the geographical boundaries of C. immitis in WA have not been well characterized, human infections have resulted from exposure in the south‐central region of the state. Since 2010, only one dog has been identified as a probable locally acquired animal case, despite pilot canine serological surveys from south‐central WA revealing a 9.8% seroprevalence. On the suspicion that clinical animal cases may be underdiagnosed and/or underreported, we assessed WA veterinarians’ knowledge, attitudes and practices regarding coccidioidomycosis. All veterinarians with active licenses in WA were invited to complete a self‐administered, web‐based survey from November 2018 to January 2019. Four hundred and twenty‐five of 2,211 (19.2%) veterinarians returned the survey and were eligible for inclusion in the final analysis. Nearly, all respondents (98.8%) had heard of coccidioidomycosis, but only 31.5% and 25.6% knew that locally acquired animal and human cases, respectively, had been reported in WA. Only half (52.6%) of participants knew that the disease was reportable. Fewer than 20% of respondents reported confidence that their knowledge of coccidioidomycosis was up to date, and 76.9% “never” or “rarely” considered the risk of disease in their patients. A statistically significant predictor of a high knowledge score (≥70%), however, included practicing in endemic counties where the Washington State Department of Health had previously delivered outreach and education services. While the results suggest some success with these activities, it is clear that information on the emergence of coccidioidomycosis is not adequately reaching veterinary practitioners in WA. The data support that more frequent CE opportunities, and dissemination of public health communications through veterinary‐specific modalities, would help fill the knowledge gap. In turn, improved diagnosis and reporting of animal cases would assist in our overall understanding the epidemiology of coccidioidomycosis in WA.

Key points
Triheteromeric NMDA receptors contain two GluN1 and two distinct GluN2 subunits and mediate excitatory neurotransmission in the CNS.
Triheteromeric GluN1/2B/2D receptors have functional properties intermediate to those of diheteromeric GluN1/2B and GluN1/2D receptors.
GluN1/2B/2D receptors are more sensitive to channel blockade by ketamine and memantine compared to GluN1/2B receptors in the presence of physiological Mg2+.
GluN2B‐selective antagonists produce robust inhibition of GluN1/2B/2D receptors, and the GluN2B‐selective positive allosteric modulator spermine enhances responses from GluN1/2B/2D but not GluN1/2A/2B receptors.
These insights into the properties of triheteromeric GluN1/2B/2D receptors are necessary to appreciate their physiological roles in neural circuit function and the actions of therapeutic agents targeting NMDA receptors.
AbstractTriheteromeric NMDA‐type glutamate receptors that contain two GluN1 and two different GluN2 subunits contribute to excitatory neurotransmission in the adult CNS. In the present study, we report properties of the triheteromeric GluN1/2B/2D NMDA receptor subtype that is expressed in distinct neuronal populations throughout the CNS. We show that neither GluN2B, nor GluN2D dominate the functional properties of GluN1/2B/2D receptors because agonist potencies, open probability and the glutamate deactivation time course of GluN1/2B/2D receptors are intermediate to those of diheteromeric GluN1/2B and GluN1/2D receptors. Furthermore, channel blockade of GluN1/2B/2D by extracellular Mg2+ is intermediate compared to GluN1/2B and GluN1/2D, although GluN1/2B/2D is more sensitive to blockade by ketamine and memantine compared to GluN1/2B in the presence of physiological Mg2+. Subunit‐selective allosteric modulators have distinct activity at GluN1/2B/2D receptors, including GluN2B‐selective antagonists, ifenprodil, EVT‐101 and CP‐101‐606, which inhibit with similar potencies but with different efficacies at GluN1/2B/2D (∼65% inhibition) compared to GluN1/2B (∼95% inhibition). Furthermore, the GluN2B‐selective positive allosteric modulator spermine enhances responses from GluN1/2B/2D but not GluN1/2A/2B receptors. We show that these key features of allosteric modulation of recombinant GluN1/2B/2D receptors are also observed for NMDA receptors in hippocampal interneurons but not CA1 pyramidal cells, which is consistent with the expression of GluN1/2B/2D receptors in interneurons and GluN1/2A/2B receptors in pyramidal cells. Altogether, we uncover previously unknown functional and pharmacological properties of triheteromeric GluN1/2B/2D receptors that can facilitate advances in our understanding of their physiological roles in neural circuit function and therapeutic drug actions.
Incubation with sodium nitrite attenuates fatigue development in intact single mouse fibres at physiological
Authors: Bailey Stephen J. , Gandra Paulo G. , Jones Andrew M. , Hogan Michael C. , Nogueira Leonardo 
Published: September 2019

Key points
Dietary nitrate supplementation increases plasma nitrite concentration, which provides an oxygen‐independent source of nitric oxide and can delay skeletal muscle fatigue.
Nitrate supplementation has been shown to increase myofibre calcium release and force production in mouse skeletal muscle during contractions at a supra‐physiological oxygen tension, but it is unclear whether nitrite exposure can delay fatigue development and improve myofibre calcium handling at a near‐physiological oxygen tension.
Single mouse muscle fibres acutely treated with nitrite had a lower force and cytosolic calcium concentration during single non‐fatiguing contractions at a near‐physiological oxygen tension.
Nitrite treatment delayed fatigue development during repeated fatiguing isometric contractions at near‐physiological, but not at supra‐physiological, oxygen tension in combination with better maintenance of myofilament calcium sensitivity and sarcoplasmic reticulum calcium pumping.
These findings improve understanding of the mechanisms by which increased skeletal muscle nitrite exposure might be ergogenic and imply that this is related to improved calcium handling.
AbstractDietary nitrate (NO3−) supplementation, which increases plasma nitrite (NO2−) concentration, has been reported to attenuate skeletal muscle fatigue development. Sarcoplasmic reticulum (SR) calcium (Ca2+) release is enhanced in isolated single skeletal muscle fibres following NO3− supplementation or NO2− incubation at a supra‐physiological but it is unclear whether NO2− incubation can alter Ca2+ handling and fatigue development at a near‐physiological . We hypothesised that NO2− treatment would improve Ca2+ handling and delay fatigue at a physiological in intact single mouse skeletal muscle fibres. Each muscle fibre was perfused with Tyrode solution pre‐equilibrated with either 20% (∼150 Torr) or 2% O2 ( = 15.6 Torr) in the absence and presence of 100 µM NaNO2. At supra‐physiological (i.e. 20% O2), time to fatigue was lowered by 34% with NaNO2 (control: 257 ± 94 vs. NaNO2: 159 ± 46 s, Cohen's d = 1.63, P < 0.05), but extended by 21% with NaNO2 at 2% O2 (control: 308 ± 217 vs. NaNO2: 368 ± 242 s, d = 1.14, P < 0.01). During the fatiguing contraction protocol completed with NaNO2 at 2% O2, peak cytosolic Ca2+ concentration ([Ca2+]c) was not different (P > 0.05) but [Ca2+]c accumulation between contractions was lower, concomitant with a greater SR Ca2+ pumping rate (P < 0.05) compared to the control condition. These results demonstrate that increased exposure to NO2− blunts fatigue development at near‐physiological, but not at supra‐physiological, through enhancing SR Ca2+ pumping rate in single skeletal muscle fibres. These findings extend our understanding of the mechanisms by which increased NO2− exposure can mitigate skeletal muscle fatigue development.

Published: September 2019

ObjectiveWith inappropriately large facemasks, it is more difficult to create a seal on the face, potentially leading to ineffective ventilation during neonatal stabilisation. We investigated whether commonly available round facemasks are of appropriate size by measuring facial dimensions in near-term and term infants using two-dimensional (2D) and three-dimensional (3D) images.DesignProspective single-centre observational study.SettingInfants born in our centre at 34–41 weeks’ gestation were eligible.InterventionPatients were photographed with 2D and 3D technique.Main outcome measuresDistances between nasion and gnathion were measured and compared with the outer diameter of various round facemasks.Methods2D and 3D images were performed using standard equipment. Correlations between gestational age and the above-mentioned distances were assessed using Pearson’s r.ResultsImages were taken from 102 infants with a mean (SD) gestational age of 37.9 (2.3) weeks. Mean distance between nasion and gnathion was 46.9 mm (5.1) in 2D and 49.9 mm (4.1) in 3D images, that is, on average 3 mm smaller in 2D than with 3D (p<0.01). Based on these measurements, round facemasks with an external diameter of 50 mm seemed fitting for most (61%) term infants and 42 mm masks for most (72%) near-term infants (GA 34–36 weeks).ConclusionsRound facemasks with an external diameter of 60 mm are too large for almost all newborn infants, while 42/50 mm round facemasks are well fitting. Important anatomical structures were only visible using 3D images.Clinical trial registration numberNCT03369028

ObjectivesThis study aimed to investigate if the use of a transition team was feasible for patients with diabetes being discharged from hospital on injectable diabetes therapies.DesignPilot, randomised controlled trial.SettingThe trial was conducted between 2014 and 2016 conjointly by a tertiary referral hospital and a community healthcare provider.ParticipantsHospital inpatients (n=105) on new injectable diabetes therapies were randomised 1:1 to transition team or standard care. The transition team received in-home diabetes education 24–48 hours postdischarge, with endocrinologist review 2–4 weeks and 16 weeks postdischarge.Main outcome measuresThe primary outcome was feasibility, defined by percentage of patients successfully receiving the intervention. Secondary outcomes included safety, defined by hospital readmission and emergency department presentations within 16 weeks postrandomisation, and treatment satisfaction, measured using Diabetes Treatment Satisfaction Questionnaire (DTSQ). Exploratory outcomes included length of stay (LOS) and change in haemoglobin A1c (HbA1c) throughout the study.ResultsThe intervention was deemed feasible (85% (95% CI 73% to 94%)). No difference in safety between groups was detected. No difference in change in HbA1c between groups was detected (standard care median HbA1c −1.5% (IQR −3.7% to −0.2%) vs transition team median HbA1c −1.9% (IQR −3.8% to −0.2%), p=0.83). There was a trend towards reduced LOS in the transition team group (per protocol, standard care median LOS 8 (IQR 5.5–12); transition team median LOS 6 (IQR 3–12), p=0.06). There was a significant improvement in patient satisfaction in the transition team (standard care median 10.5 (IQR 8.5–16); transition team DTSQ change version median 15 (IQR 10–17.5), p=0.047), although interpretability is limited by missing data.ConclusionThis study demonstrated that the use of a novel transition diabetes team is a feasible alternative model of care.
The ‘Hikikomori’ syndrome: worldwide prevalence and co-occurring major psychiatric disorders: a systematic review and meta-analysis protocol

Published: September 2019

IntroductionThe ‘Hikikomori’ syndrome (HS) consists of prolonged and severe social withdrawal. It has been studied first in Japan and recently has increasingly drawn the attention of researchers and clinicians all over the world. It is unclear whether it exists in other cultural contexts than Asia. The existing systematic reviews did not provide a quantitative synthesis on its prevalence. In addition, a summary of the co-occurring rates of psychiatric disorders is lacking. To provide a more comprehensive understanding of the clinical picture, it seems important to investigate which psychiatric disorders listed in the classification systems are most frequently associated with this psychological condition affecting young people. This paper describes a systematic review and meta-analysis protocol summarising worldwide prevalence of the HS in general population and clinical samples with psychiatric disorders. The review will also assess the co-occurrence between HS and each psychiatric disorder defined by any version of the Diagnostic and Statistical Manual of Mental Disorders (DSM) or International Classification of Diseases (ICD) in any clinical samples with psychiatric disorders.Methods and analysisA systematic review will be conducted according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Studies will be included if they use youth aged 12–35 years, recruited from general population or population with psychiatric disorders, if they use international criteria to diagnose HS. No restriction about design or language will be applied. The search will be conducted during the first week of November 2019 by two independent reviewers through the databases Scopus, PubMed, PsycINFO, Web of Science, by examining study references, by looking for conference proceedings/dissertations/theses, by contacting study corresponding authors. Random-effect meta-analysis will be performed by computing effect sizes as logit event rates. Study quality will be assessed through the Newcastle-Ottawa Scale.Ethics and disseminationThe current review does not require ethics approval. The results will be disseminated through conference presentations and publications in peer-reviewed journals.PROSPERO registration numberCRD 42018098747.

ObjectiveTo review systematically the evidence on the costs and cost-effectiveness of deinstitutionalisation for adults with intellectual disabilities.DesignSystematic review.PopulationAdults (aged 18 years and over) with intellectual disabilities.InterventionDeinstitutionalisation, that is, the move from institutional to community settings.Primary and secondary outcome measuresStudies were eligible if evaluating within any cost-consequence framework (eg, cost-effectiveness analysis, cost–utility analysis) or resource use typically considered to fall within the societal viewpoint (eg, cost to payers, service-users, families and informal care costs).SearchWe searched MEDLINE, PsycINFO, CENTRAL, CINAHL, EconLit, Embase and Scopus to September 2017 and supplemented this with grey literature searches and handsearching of the references of the eligible studies. We assessed study quality using the Critical Appraisals Skills Programme suite of tools, excluding those judged to be of poor methodological quality.ResultsTwo studies were included; both were cohort studies from the payer perspective of people leaving long-stay National Health Service hospitals in the UK between 1984 and 1992. One study found that deinstitutionalisation reduced costs, one study found an increase in costs.ConclusionA wide-ranging literature review found limited evidence on costs associated with deinstitutionalisation for people with intellectual disabilities. From two studies included in the review, the results were conflicting. Significant gaps in the evidence base were observable, particularly with respect to priority populations in contemporary policy: older people with intellectual disabilities and serious medical illness, and younger people with very complex needs and challenging behaviours.PROSPERO registration numberCRD42018077406

ObjectivesRecent meta-analyses of eradication therapy inHelicobacter pylori-infected adults reported significant reductions in gastric carcinoma risk. However, concerns about supporting unfocused screening and eradication programme in healthy, asymptomatic populations have arisen. We performed a systematic review and Bayesian meta-analysis to provide an accurate interpretation of randomised evidence on the preventive effectiveness of eradication therapy on gastric carcinoma risk.MethodsWe searched databases including PubMed, Cochrane Central and Embase for reference and citation tracking without language restrictions, from inception through 31 July 2018. Paired investigators independently selected randomised controlled trials (RCTs) comparing eradication therapy with placebo or no treatment for asymptomatic or dyspepticH. pylori-infected adults with no previous gastric carcinoma. The main outcome was gastric carcinoma incidence; secondary outcomes included gastric carcinoma-specific, non-gastric carcinoma and all-cause mortality.ResultsA total of 5 population-based and 2 outpatient care-based RCTs involving 7303 adults were eligible. Eradication algorithms were heterogeneous, and unsuccessful eradication and reinfection were frequently observed. A Bayesian meta-analysis with competing risk outcomes found low-certainty evidence that eradication therapy might be more likely than control to reduce gastric carcinoma risk (HR=0.65; 95% credible interval (CrI) 0.41 to 1.0;I2=11%). The CrIs included the null effects across the subgroup and sensitivity analyses, apart from those based on particular models that excluded two RCTs that enrolled subjects with specific histological findings only (HR=0.55; CrI 0.30 to 0.89;I2=14%). The uncertainty of the average 41% risk reduction in gastric carcinoma-specific mortality included a clinically important mortality risk increase (HR=0.59 favouring eradication therapy; CrI 0.25 to 1.20;I2=13%; low certainty).ConclusionsThere is insufficient evidence to support or refute the effectiveness of eradication therapy in preventing gastric carcinoma inH. pylori-infected, high-risk populations. Rigorously conducted large RCTs of healthy infected adults only would provide evidence of the true efficacy of successful eradication.PROSPERO registration number:CRD42014009245.

IntroductionAchieving efficacious and safe treatments for unstable angina pectoris (UAP) is still a challenging clinical problem. The availability of different oral Chinese patent medicines frequently poses a practical challenge to clinicians, namely, which one to choose as first-line regimen for treatment. This study aims to examine the comparative effectiveness and safety of oral Chinese patent medicines for UAP on the national essential drugs list of China.Methods and analysisWe will conduct a network meta-analysis (NMA) of all randomised controlled trials to evaluate the use of oral Chinese patent medicines as adjuvant for the treatment of UAP. We will explore eight electronic databases from their inception to June 2018 and search for grey literature. Primary outcomes include mortality and the cardiovascular events. Secondary outcomes include: (1) symptom improvement; (2) ECG improvement; (3) frequency of acute angina attack; (4) duration of angina; (5) adverse effects. Two independent authors will screen titles and abstracts, review full texts, extract data, assess the risk of bias using the Cochrane risk of bias tool and assess the quality of evidence and strength of the recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). If adequate data are available, NMA will be performed with Bayesian analysis methods.Ethics and disseminationThe NMA will help us to reduce the uncertainty of interventions and help clinicians to make optimal and more accurate therapeutic decisions for adults with UAP. Therefore, we will publish the findings of this study in a peer-reviewed journal. No ethics approval is necessary for this study based on the nature of its design.Trial registration numberCRD42018092822.
Taking a systems approach to explore the impacts and outcomes of a research and evaluation capacity building partnership: a protocol
Authors: Tobin Rochelle , Hallett Jonathan , Lobo Roanna , Maycock Bruce Richard 
Published: September 2019

IntroductionPartnership models that bring researchers, policymakers and service providers closer together are gaining traction as a strategy to improve public health practice. Yet, there is little evidence of how these models work, or indeed if they do work. The Sexual Health and Blood-borne Virus Applied Research and Evaluation Network (SiREN) is one such model. SiREN is a partnership between researchers, policymakers and service providers that aims to develop the research and evaluation capacity and evidence-informed decision making capability of professionals working to address sexual health and bloodborne virus issues in Western Australia. This study will use a systems approach to identify the mechanisms of action, impacts and outcomes of SiREN and inform the development of evaluation tools.Methods and analysisData will be collected from organisational documents, surveys, in-depth interviews and a workshop. It will be analysed using a complex adaptive systems lens and findings will be used to inform the development of a type of qualitative systems model called a causal loop diagram. The causal loop diagram will illustrate the: contextual factors influencing engagement; mechanisms of action; and impacts and outcomes of SiREN. Evaluation tools will then be developed that can be used to assess the indicators identified in the causal loop diagram.Ethics and disseminationEthics approval was obtained from the Curtin University Human Research Ethics Committee (approval number: HRE2017-0090). Participants will be free to withdraw from the study at any point and confidentiality will be maintained by de-identifying participant responses in any published or shared data. The findings from this study will be shared in conference presentations, reports, peer-reviewed journals and online through websites and social media.
