Arabidopsis Root Microbiome Microfluidic (ARMM) Device for Imaging Bacterial Colonization and Morphogenesis of Arabidopsis Roots.

Imaging the spatiotemporal dynamics of host-microbiota interactions is of particular interest for augmenting our understanding of these complex systems. This is especially true of plant-microbe interactions happening around, on, and inside plant roots where relatively little is understood about the dynamics of these systems. Over the past decade, a number of microfluidic devices have been developed to grow plants hydroponically in gnotobiotic conditions and image morphogenesis of the root and/or dynamics with fluorescently labeled bacteria from the plant root microbiome.

Impairment's Role in the Pathway From Externalizing Psychopathology to Depressive Symptoms in Adolescents With ADHD.

Objective: This study examined the role of academic, social, and family impairment in the pathway from externalizing psychopathology to depression among young adolescents with ADHD in a multiple mediation model.

Method: The sample included adolescents with ADHD enrolled in an intervention trial. Parent ratings of externalizing psychopathology were measured at eligibility assessment, adolescent self-reported depressive symptoms were measured at eligibility and at the end of treatment, and parent-rated impairment was measured in the middle of treatment.

Clinical Outcomes and Risk Stratification of Early-Stage Melanoma Micrometastases From an International Multicenter Study: Implications for the Management of American Joint Committee on Cancer IIIA Disease.

Purpose: Indications for offering adjuvant systemic therapy for patients with early-stage melanomas with low disease burden sentinel node (SN) micrometastases, namely, American Joint Committee on Cancer (AJCC; eighth edition) stage IIIA disease, are presently controversial. The current study sought to identify high-risk SN-positive AJCC stage IIIA patients who are more likely to derive benefit from adjuvant systemic therapy.

Methods: Patients were recruited from an intercontinental (Australia/Europe/North America) consortium of nine high-volume cancer centers.

Evaluation of the Indications for Sentinel Node Biopsy in Early-Stage Melanoma with the Advent of Adjuvant Systemic Therapy: An International, Multicenter Study.

Background: Patients presenting with early-stage melanoma (AJCC pT1b-pT2a) reportedly have a relatively low risk of a positive SNB (~5-10%). Those patients are usually found to have low-volume metastatic disease after SNB, typically reclassified to AJCC stage IIIA, with an excellent prognosis of ~90% 5-year survival. Currently, adjuvant systemic therapy is not routinely recommended for most patients with AJCC stage IIIA melanoma.

Objectives: To determine the clinical and cost effectiveness of a multifactorial fall prevention programme compared with usual care in long term care homes.

Design: Multicentre, parallel, cluster randomised controlled trial.

Setting: Long term care homes in the UK, registered to care for older people or those with dementia.

A multizone cerebellar chip for bioinspired adaptive robot control and sensorimotor processing.

The cerebellum is a neural structure essential for learning, which is connected via multiple zones to many different regions of the brain, and is thought to improve human performance in a large range of sensory, motor and even cognitive processing tasks. An intriguing possibility for the control of complex robotic systems would be to develop an artificial cerebellar chip with multiple zones that could be similarly connected to a variety of subsystems to optimize performance. The novel aim of this paper, therefore, is to propose and investigate a multizone cerebellar chip applied to a range of tasks in robot adaptive control and sensorimotor processing.

A single bacterial genus maintains root growth in a complex microbiome.

Plants grow within a complex web of species that interact with each other and with the plant. These interactions are governed by a wide repertoire of chemical signals, and the resulting chemical landscape of the rhizosphere can strongly affect root health and development. Here, to understand how interactions between microorganisms influence root growth in Arabidopsis, we established a model system for interactions between plants, microorganisms and the environment.

Prescription opioid misuse among university students: A systematic review.

Misuse of prescription opioids has substantially increased in the past decade among the general population, including among university students. Relative to the literature concerning opioid misuse among the general population, little information is available regarding the college student population. The purpose of the present study was to conduct a systematic review of the literature concerning the prevalence of prescription opioid misuse among the university student population.

Application of a Glucose Dehydrogenase-Fused with Zinc Finger Protein to Label DNA Aptamers for the Electrochemical Detection of VEGF.

Aptamer-based electrochemical sensors have gained attention in the context of developing a diagnostic biomarker detection method because of their rapid response, miniaturization ability, stability, and design flexibility. In such detection systems, enzymes are often used as labels to amplify the electrochemical signal. We have focused on glucose dehydrogenase (GDH) as a labeling enzyme for electrochemical detection owing to its high enzymatic activity, availability, and well-established electrochemical principle and platform.

Clinical and cost-effectiveness of a diabetes education and behavioural weight management programme versus a diabetes education programme in adults with a recent diagnosis of type 2 diabetes: study protocol for the Glucose Lowering through Weight management (GLoW) randomised controlled trial.

Introduction: People with type 2 diabetes (T2D) can improve glycaemic control or even achieve remission through weight loss and reduce their use of medication and risk of cardiovascular disease. The Glucose Lowering through Weight management (GLoW) trial will evaluate whether a tailored diabetes education and behavioural weight management programme (DEW) is more effective and cost-effective than a diabetes education (DE) programme in helping people with overweight or obesity and a recent diagnosis of T2D to lower their blood glucose, lose weight and improve other markers of cardiovascular risk.

Methods And Analysis: This study is a pragmatic, randomised, single-blind, parallel group, two-arm, superiority trial.

Adaptive treatment and robust control.

A control theory perspective on determination of optimal dynamic treatment regimes is considered. The aim is to adapt statistical methodology that has been developed for medical or other biostatistical applications to incorporate powerful control techniques that have been designed for engineering or other technological problems. Data tend to be sparse and noisy in the biostatistical area and interest has tended to be in statistical inference for treatment effects.

Sensorimotor maps can be dynamically calibrated using an adaptive-filter model of the cerebellum.

Substantial experimental evidence suggests the cerebellum is involved in calibrating sensorimotor maps. Consistent with this involvement is the well-known, but little understood, massive cerebellar projection to maps in the superior colliculus. Map calibration would be a significant new role for the cerebellum given the ubiquity of map representations in the brain, but how it could perform such a task is unclear.

Acceptability of the Medication Adherence for Patients Support intervention to improve adherence to patients prescribed medications for hypertension or comorbidities, as an adjunct to primary care: A qualitative study.

Tailored interventions delivered via text and voice messages can improve adherence to multiple medications. However, no such intervention has been developed in the UK primary-care setting. We conducted focus groups with 12 patients with hypertension, type 2 diabetes, or both conditions, presumed to be non-adherent and recruited from deprived neighborhoods, to assess the acceptability and inform the development of an intervention to provide ongoing support for adherence, as an adjunct to primary-care consultations.

Randomised controlled trial of a theory-based behavioural intervention to reduce formula milk intake.

Objective: To assess the efficacy of a theory-based behavioural intervention to prevent rapid weight gain in formula milk-fed infants.

Design: In this single (assessor) blind, randomised controlled trial, 669 healthy full-term infants receiving formula milk within 14 weeks of birth were individually randomised to intervention (n=340) or attention-matched control (n=329) groups. The intervention aimed to reduce formula milk intakes, and promote responsive feeding and growth monitoring to prevent rapid weight gain (≥+0.

Clinical effectiveness and cost-effectiveness of issuing longer versus shorter duration (3-month vs. 28-day) prescriptions in patients with chronic conditions: systematic review and economic modelling.

Background: To reduce expenditure on, and wastage of, drugs, some commissioners have encouraged general practitioners to issue shorter prescriptions, typically 28 days in length; however, the evidence base for this recommendation is uncertain.

Objective: To evaluate the evidence of the clinical effectiveness and cost-effectiveness of shorter versus longer prescriptions for people with stable chronic conditions treated in primary care.

Design/data Sources: The design of the study comprised three elements.

A Syst-OMICS Approach to Ensuring Food Safety and Reducing the Economic Burden of Salmonellosis.

The Syst-OMICS consortium is sequencing 4,500 genomes and building an analysis pipeline for the study of genome evolution, antibiotic resistance and virulence genes. Metadata, including phenotypic as well as genomic data, for isolates of the collection are provided through the Foodborne Syst-OMICS database (SalFoS), at https://salfos.ibis.

Pragmatic randomised controlled trial to evaluate the effectiveness and cost effectiveness of a multi-component intervention to reduce substance use and risk-taking behaviour in adolescents involved in the criminal justice system: A trial protocol (RISKIT-CJS).

Background: Adolescence is a critical developmental stage when young people make lifestyle choices that have the potential to impact on their current and future health and social wellbeing. The relationship between substance use and criminal activity is complex but there is clear evidence that the prevalence of problematic substance use is far higher among adolescent offenders than the general adolescent population. Adolescent offenders are a marginalized and vulnerable population who are significantly more likely to experience health and social inequalities in later life than their non-offending peers.

A randomised controlled trial of three very brief interventions for physical activity in primary care.

Background: Very brief interventions (VBIs) for physical activity are promising, but there is uncertainty about their potential effectiveness and cost. We assessed potential efficacy, feasibility, acceptability, and cost of three VBIs in primary care, in order to select the most promising intervention for evaluation in a subsequent large-scale RCT.

Methods: Three hundred and ninety four adults aged 40-74 years were randomised to a Motivational (n = 83), Pedometer (n = 74), or Combined (n = 80) intervention, delivered immediately after a preventative health check in primary care, or control (Health Check only; n = 157).

Cerebellar-inspired algorithm for adaptive control of nonlinear dielectric elastomer-based artificial muscle.

Electroactive polymer actuators are important for soft robotics, but can be difficult to control because of compliance, creep and nonlinearities. Because biological control mechanisms have evolved to deal with such problems, we investigated whether a control scheme based on the cerebellum would be useful for controlling a nonlinear dielectric elastomer actuator, a class of artificial muscle. The cerebellum was represented by the adaptive filter model, and acted in parallel with a brainstem, an approximate inverse plant model.

When and how to update systematic reviews: consensus and checklist.

Updating of systematic reviews is generally more efficient than starting all over again when new evidence emerges, but to date there has been no clear guidance on how to do this. This guidance helps authors of systematic reviews, commissioners, and editors decide when to update a systematic review, and then how to go about updating the review.

Effectiveness and cost-effectiveness of a very brief physical activity intervention delivered in NHS Health Checks (VBI Trial): study protocol for a randomised controlled trial.

Background: Physical activity interventions that are targeted at individuals can be effective in encouraging people to be more physically active. However, most such interventions are too long or complex and not scalable to the general population. This trial will test the effectiveness and cost-effectiveness of a very brief physical activity intervention when delivered as part of preventative health checks in primary care (National Health Service (NHS) Health Check).
