Abstract
INTRODUCTION Severe respiratory syncytial virus (RSV) disease is most prevalent during infancy, particularly in those born prematurely, who benefit least from maternal antibody transfers. Maternal immunization is an attractive prevention leading to vaccine clinical trials. This meta-analysis aimed to evaluate recent maternal RSV vaccine trials. METHODS Following PRISMA-P guidelines for systematic reviews and registered at https://www.crd.york.ac.uk/prospero, this study shortlisted six randomized clinical trials of suitable quality from four databases. Meta-analysis evaluated vaccine safety, immunogenicity, and efficacy in infants and their mothers. RESULTS From random-effects and fixed-effects meta-analysis between trial and control arms, the maternal post-vaccination geometric antibody (Ab) titers showed pooled standard mean differences (SMDs [95% CI]) at delivery of (4.14 [2.91-5.37]), (3.95 [2.79-5.11]), and (12.20 [7.76, 16.64]) for RSV neutralizing Ab A, B, and F IgG, respectively. Vaccine administration was more likely than placebo to cause local pain, erythema, swelling, and systemic myalgia. Furthermore, the Ab levels in infants at birth showed pooled SMDs of each RSV A (3.9 [2.81-4.99]), RSV B (1.86 [1.09-2.62]), and RSV F IgG (2.24 [1.24-3.23]). The overall reduction of RSV-related lower respiratory tract infections and hospitalizations in the first 6 months of life was 52% and 48%, respectively. CONCLUSIONS Not only does antenatal RSV vaccination look safe and immunogenic in vaccinated mothers, but it also reliably provides effective antibody levels in infants and diminishes RSV-related severe disease in infants under 6 months of age.

Abstract
BACKGROUND Schools are an attractive platform for improving the dietary knowledge, attitudes and behaviors of children and their families, yet limited nutrition knowledge amongst educators can impede nutrition education efforts. Information and communication technology (ICT) can potentially overcome this barrier, yet there is limited evidence for its effectiveness in school settings in low- and middle-income countries. METHODS We implemented a randomized field experiment in 50 schools in the North Region of Cameroon to assess the effectiveness of a school-based nutrition education program at improving the nutrition knowledge of fifth and sixth grade students and their parents. We evaluate the relative effectiveness of video-based versus typical classroom instruction. Nutrition knowledge is assessed using a pre-post questionnaire and analyzed using analysis of covariance. RESULTS We find that students exposed to the video treatment improved their nutrition knowledge scores by 0.45 standard deviation more (equivalent to an additional 1.3 out of 14 correct answers) than students that received traditional classroom instruction. There is no differential impact of video on the nutrition knowledge scores of parents. CONCLUSION Videos can improve knowledge gains compared with typical classroom instruction, but questions remain as to the conditions under which videos and other ICT are most effective as instructional tools.

Abstract
BACKGROUND Respiratory infection with nontuberculous mycobacteria (NTM) in children with cystic fibrosis (CF) has increased in prevalence. The condition is difficult to diagnose and treatments are complex with limited evidence to guide practice. This study describes the approaches to diagnosis, management and consequences of treatment in a multicentre cohort of children with CF in the UK. METHODS Retrospective data were collected from 11 CF specialist centres from patients less than 17 years old, treated for NTM infection between 2006 and 2017. Descriptive statistics were used to describe the clinical characteristics of children treated. Treatment regimens, adverse events and success of treatment, with respect to lung function and culture conversion, were evaluated. RESULTS Data from 70 patients treated for NTM pulmonary disease were collated (60 Mycobacterium abscessus complex (MABSC); 10 M. avium complex (MAC)). Older age and previous diagnosis of allergic bronchopulmonary aspergillosis were all significantly associated with NTM. There was a wide variance in drug choice and side effects were reported with all agents. NTM eradication occurred in 80% of patients with MAC and 48% with MABSC, with variable outcomes on lung function. CONCLUSIONS Diagnosis and treatment of NTM infection in children with CF is challenging. Treatment success is not guaranteed, particularly for MABSC. Large clinical trials are urgently required to evaluate treatment regimes and their suitability and efficacy in children.

Abstract
The impact of published research is sometimes measured by the number of citations an individual article accumulates. However, the time from publication to citation can be extensive. Years may pass before authors are able to measure the impact of their publication. Social media provides individuals and organizations a powerful medium with which to share information. The power of social media is sometimes harnessed to share scholarly works, especially journal article citations and quotes. A non-traditional bibliometric is required to understand the impact social media has on disseminating scholarly works/research. The International Journal of Mental Health Nursing (IJMHN) appointed a social media editor as of 1 January 2017 to implement a strategy to increase the impact and reach of the journal's articles. To measure the impact of the IJMHN social media strategy, quantitative data for the eighteen months prior to the social media editor start date, and the eighteen months after that date (i.e.: from 01 July 2015 to 30 June 2018) were acquired and analysed. Quantitative evidence demonstrates the effectiveness of one journal's social media strategy in increasing the reach and readership of the articles it publishes. This information may be of interest to those considering where to publish their research, those wanting to amplify the reach of their research, those who fund research, and journal editors and boards.

Abstract
The characterization of an amplified piezoelectric actuator (APA) as a new axial scanning method for multiple-reference optical coherence tomography (MR-OCT) is described. MR-OCT is a compact optical imaging device based on a recirculating reference-arm-scanning optical delay using a partial mirror that can enhance the imaging depth range by more than 10 times the reference mirror's scanning amplitude. The scanning amplitude of the used APA was varied between 30 μm and 250 μm, depending on the scanning frequency of between 0.8 kHz and 1.2 kHz. A silver-coated miniature mirror was attached to the APA via ultraviolet-cured optical adhesive, and the light source was a super-luminescent diode with 1310 nm center wavelength and 56 nm bandwidth. The sensitivity was measured with and without the partial mirror in the reference delay line as a function of scan speed, frequency, and range, therefore providing results for MR-OCT and TD-OCT modes. It was found that the APA provides more than twice the mechanical scanning range compared to other opto-mechanic actuators, but results indicate degradation of signal-to-noise ratio and sensitivity at larger imaging depths. In conjunction with MR-OCT, the scan range of maximum 200 μm can be enhanced up to 1-1.5 mm by using a reduced amount of orders of reflections, which could be of interest to increase sensitivity in the future.

Abstract
OBJECTIVES We explored children's views on research without prior consent (RWPC) and sought to identify ways of involving children in research discussions. DESIGN Qualitative interview study. SETTING Participants were recruited through a UK children's hospital and online advertising. PARTICIPANTS 16 children aged 7-15 years with a diagnosis of asthma (n=14) or anaphylaxis (n=2) with recent (<12 months) experience of emergency care. RESULTS Children were keen to be included in medical research and viewed RWPC as acceptable in emergency situations if trial interventions were judged safe. Children trusted that doctors would know about their trial participation and act in their best interests. All felt that children should be informed about the research following their recovery and involved in discussions with a clinician or their parent(s) about the use of data already collected as well as continued participation in the trial (if applicable). Participants suggested methods to inform children about their trial participation including an animation. CONCLUSIONS Children supported, and were keen to be involved in, clinical trials in emergency situations. We present guidance and an animation that practitioners and parents might use to involve children in trial discussions following their recovery.

Abstract
Influenza virus infection continues to cause widespread morbidity and mortality, resulting in major challenges for healthcare systems. Current influenza vaccines are of limited efficacy against mismatched or emerging new virus strains. Recent efforts are focused on the development of novel vaccines capable of conferring broad protection against various influenza virus subtypes. We have studied the potential of Modified Vaccinia Ankara (MVA)-vectored vaccines expressing nucleoprotein and matrix protein 1 (MVA-NP+M1) to induce cross-reactive mucosal immunity using human adenotonsillar mononuclear cell (MNC) culture system with flow cytometry and ELISPOT analysis.
Influenza NP and M1 antigens were abundantly expressed following vaccine stimulation in MNC particularly in B cells and dendritic cells. M1-specific T cell response was analyzed in detail, and MVA-NP+M1 was shown to activate IFN-γ-producing CD8+ T cells against conserved M1 epitopes. M158–66-specific CD8+ T cells in HLA-matched individuals were markedly increased in an age-dependent manner. These M1-specific T cells coexpressed cytotoxic molecules such as perforin and granzyme A and B. Upon the recognition of M158–66 peptide, these cells displayed marked increase in surface CD107a expression (implicating degranulation), together with the production of pro-inflammatory cytokines including IFN-γ and TNF-α, that correlated to their ability to kill the peptide-pulsed target cells.
In summary, we showed MVA-NP+M1 activates conserved influenza antigen-specific cytotoxic T cell response in human NALT. The results suggest MVA-NP+M1 vaccine has the potential to induce cross-reactive mucosal T cell immunity against different types of influenza viruses.

Abstract
Congenital hypopituitarism (CH) is characterized by the deficiency of one or more pituitary hormones and can present alone or in association with complex disorders. Congenital hyperinsulinism (CHI) is a disorder of unregulated insulin secretion despite hypoglycaemia that can occur in isolation or as part of a wider syndrome. Molecular diagnosis is unknown in many cases of CH and CHI. The underlying genetic etiology causing the complex phenotype of CH and CHI is unknown. In this study, we identified a de novo heterozygous mutation in the developmental transcription factor, forkhead box A2, FOXA2 (c.505T>C, p.S169P) in a child with CHI and CH with craniofacial dysmorphic features, choroidal coloboma and endoderm-derived organ malformations in liver, lung and gastrointestinal tract by whole exome sequencing. The mutation is at a highly conserved residue within the DNA binding domain. We demonstrated strong expression of Foxa2 mRNA in the developing hypothalamus, pituitary, pancreas, lungs and oesophagus of mouse embryos using in situ hybridization. Expression profiling on human embryos by immunohistochemistry showed strong expression of hFOXA2 in the neural tube, third ventricle, diencephalon and pancreas. Transient transfection of HEK293T cells with Wt (Wild type) hFOXA2 or mutant hFOXA2 showed an impairment in transcriptional reporter activity by the mutant hFOXA2. Further analyses using western blot assays showed that the FOXA2 p.(S169P) variant is pathogenic resulting in lower expression levels when compared with Wt hFOXA2. Our results show, for the first time, the causative role of FOXA2 in a complex congenital syndrome with hypopituitarism, hyperinsulinism and endoderm-derived organ abnormalities.

Abstract
Background De novo truncating and splicing mutations in the additional sex combs-like 3 (ASXL3) gene have been implicated in the development of Bainbridge-Ropers syndrome (BRPS) characterised by severe developmental delay, feeding problems, short stature and characteristic facial features. Case presentation We describe, for the first time, a patient with severe short stature, learning difficulties, feeding difficulties and dysmorphic features with a novel compound heterozygous mutation in ASXL3.Additionally the patient also has primary insulin like growth factor-1 (IGF1) deficiency. The mutations occur in exon 11 and proximal part of exon 12 and are strongly conserved at the protein level across various species. In-silico analyses using PolyPhen-2 and SIFT predict the amino acid substitutions to be potentially deleterious to the protein function. Detailed bioinformatics analysis show that the molecular defects caused by the two compound heterozygous mutations synergistically impact on two points of the molecular interaction network of ASXL3. Conclusion We hypothesise that ASXL3 potentially has a role in transcriptional activation of IGF1 involved in signalling pathways that regulate cell proliferation and growth, which could be contributing to short stature encountered in these patients.

Abstract
MK 3814 is a potent and selective antagonist of the A2a receptor. A2a receptor antagonists have the potential for the treatment of Parkinson disease. Three distinct isotopically labelled forms of MK 3814 were synthesized. [3 H]MK 3814 was prepared for a preliminary absorption, distribution, metabolism, and excretion data (ADME) evaluation of the compound and [14 C]MK 3814 for more definitive ADME work, including an absorption, metabolism, and excretion study in man. In addition, [2 H4 ]MK 3814 was prepared as an internal standard for a liquid chromatography mass spectrometry bioanalytical method. This paper discusses the synthesis of 3 isotopically labelled forms of MK 3814.

Abstract
BACKGROUND Acute bronchiolitis is the most common cause of hospitalisation in infancy. Supportive care and oxygen are the cornerstones of management. A Cochrane review concluded that the use of nebulised 3% hypertonic saline (HS) may significantly reduce the duration of hospitalisation. OBJECTIVE To test the hypothesis that HS reduces the time to when infants were assessed as being fit for discharge, defined as in air with saturations of > 92% for 6 hours, by 25%. DESIGN Parallel-group, pragmatic randomised controlled trial, cost-utility analysis and systematic review. SETTING Ten UK hospitals. PARTICIPANTS Infants with acute bronchiolitis requiring oxygen therapy were allocated within 4 hours of admission. INTERVENTIONS Supportive care with oxygen as required, minimal handling and fluid administration as appropriate to the severity of the disease, 3% nebulised HS every ± 6 hours. MAIN OUTCOME MEASURES The trial primary outcome was time until the infant met objective discharge criteria. Secondary end points included time to discharge and adverse events. The costs analysed related to length of stay (LoS), readmissions, nebulised saline and other NHS resource use. Quality-adjusted life-years (QALYs) were estimated using an existing utility decrement derived for hospitalisation in children, together with the time spent in hospital in the trial. DATA SOURCES We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials and other databases from inception or from 2010 onwards, searched ClinicalTrials.gov and other registries and hand-searched Chest, Paediatrics and Journal of Paediatrics to January 2015. REVIEW METHODS We included randomised/quasi-randomised trials which compared HS versus saline (± adjunct treatment) or no treatment. We used a fixed-effects model to combine mean differences for LoS and assessed statistical heterogeneity using the I (2) statistic. RESULTS The trial randomised 158 infants to HS (n = 141 analysed) and 159 to standard care (n = 149 analysed). There was no difference between the two arms in the time to being declared fit for discharge [median 76.6 vs. 75.9 hours, hazard ratio (HR) 0.95, 95% confidence interval (CI) 0.75 to 1.20] or to actual discharge (median 88.5 vs. 88.7 hours, HR 0.97, 95% CI 0.76 to 1.23). There was no difference in adverse events. One infant developed bradycardia with desaturation associated with HS. Mean hospital costs were £2595 and £2727 for the control and intervention groups, respectively (p = 0.657). Incremental QALYs were 0.0000175 (p = 0.757). An incremental cost-effectiveness ratio of £7.6M per QALY gained was not appreciably altered by sensitivity analyses. The systematic review comprised 15 trials (n = 1922) including our own. HS reduced the mean LoS by -0.36 days (95% CI -0.50 to -0.22 days). High levels of heterogeneity (I (2) = 78%) indicate that the result should be treated cautiously. CONCLUSIONS In this trial, HS had no clinical benefit on LoS or readiness for discharge and was not a cost-effective treatment for acute bronchiolitis. Claims that HS achieves small reductions in LoS must be treated with scepticism. FUTURE WORK Well-powered randomised controlled trials of high-flow oxygen are needed.

Abstract
AIM To develop and validate a bronchiolitis severity scoring instrument for use by nurses and other healthcare professions. BACKGROUND Bronchiolitis is a viral lower respiratory tract infection of infancy. In industrialized countries, admission rates have increased over the last decade with up to 3% of all infants born being admitted to hospital. A small number of these hospitalized infants will require admission to critical care for either invasive or non-invasive ventilation. During the seasonal epidemic, the number of unplanned admissions to critical care with bronchiolitis substantially increases. DESIGN We will use a mixed methods study design. METHODS We will use scale development and psychometric methods to develop a scoring instrument and to test the instrument for content, construct and criterion validity and reliability in several different clinical locations. This study protocol has been reviewed and approved by the NHS National Research Ethics Service, January 2011. DISCUSSION There is an urgent need to develop a valid and reliable severity scoring instrument sensitive to clinical changes in the infant, to facilitate clinical decision-making and help standardize patient care. Furthermore, a valid and reliable scoring instrument could also be used as a proxy patient-reported outcome measure to evaluate the efficacy of clinical interventions in randomized controlled trials.

Abstract
Arable land in China has been decreasing as a result of rapid population growth and economic development as well as urban expansion, especially in developed regions around cities where quality farmland quickly disappears. This paper analyzed changes in arable land utilization during 1993-2008 in the Pinggu district, Beijing, China, developed a multinomial logit (MNL) model to determine spatial driving factors influencing arable land-use change, and simulated arable land transition probabilities. Land-use maps, as well as social-economic and geographical data were used in the study. The results indicated that arable land decreased significantly between 1993 and 2008. Lost arable land shifted into orchard, forestland, settlement, and transportation land. Significant differences existed for arable land transitions among different landform areas. Slope, elevation, population density, urbanization rate, distance to settlements, and distance to roadways were strong drivers influencing arable land transition to other uses. The MNL model was proved effective for predicting transition probabilities in land use from arable land to other land-use types, thus can be used for scenario analysis to develop land-use policies and land-management measures in this metropolitan area.

Abstract
OBJECTIVES The objective of this study was to establish the level of awareness of HAND among healthcare providers, the screening tools that are currently used in its detection and factors that limit cognitive assessments. METHODS We distributed a 12-item questionnaire to doctors and nurses who work in the Department of Genitourinary Medicine and Infectious Disease (GUIDE) service and also to doctors who work in the emergency department (ED) at St James Hospital. RESULTS 35 surveys were collected, 54% (n = 19) from the GUIDE service and 46% (n = 16) from the ED. 82% (n = 29) of participants were doctors from interns to consultants. There was reasonable appreciation among participants with regards the prevalence of neurocognitive impairment (estimated at 29.1% among patients on HAART, and 39.3% among patients not on HAART). Screening tools were rarely used by GUIDE and ED clinicians (25% vs. 15% of the time). The Mini Mental State Examination (MMSE) was previously used by 37% (n = 13) of the group. Very few people had used the HIV Dementia Scale (HIVDS) 6% (n = 2). 34% of respondents felt that 'Orientation in Person, Place and Time was a sufficient screening tool for cognitive assessment'. Lack of time, exposed environment and lack of availability of screening tool were cited as limitations to cognitive screening in the ED environment. CONCLUSIONS This study examines awareness of HAND among healthcare providers and also reasons for inadequate assessment. There is a need for consensus on screening guidelines. A quick, easy to use and readily available screening tool may have a role in the acute setting in identifying high-risk patients.

Abstract
We present the case of a 48-year-old HIV-positive man, who developed acute onset of pain in both upper limbs associated with proximal weakness and distal paraesthesia. Eight weeks prior to this presentation he had had varicella zoster affecting his right S1 dermatome. CD4 count was 355 cells/mm(3) and he was antiretroviral therapy (ART) naive. Power was 0/5 proximally and 4/5 distally in the upper limbs. Reflexes were absent and there was sensory loss in the C5, C6 and T1 dermatomes. Cerebrospinal fluid (CSF) examination showed a lymphocytosis with low glucose; however, CSF Mycobacterium tuberculosis (TB), and herpes simplex virus polymerase chain reaction (HSV PCR) were negative as was syphilis serology. Electromyography showed marked motor axonal loss. Magnetic resonance imaging (MRI) did not show any cervical spinal lesion. Varicella zoster virus (VZV) PCR was positive in the CSF. He was treated with high-dose intravenous aciclovir with good resolution of his syndrome over time and was commenced on ART. We believe this to be the first case report of varicella reactivation causing bilateral neuralgic amyotrophy in an HIV-positive patient.

Abstract
A retrospective chart review was carried out at the HIV clinic in St. James's Hospital, Dublin to examine the rate of cognitive impairment through the use of surrogate markers for cognitive impairment. 500 consecutive hospital charts were reviewed. There were 306 men and 194 women. Median age was 37. The most common mode of transmission was heterosexual. 45% had a nadir CD4 < 200. 78.6% were on antiretroviral therapy and 72.26% were virally suppressed. 69/500 patients (13.8%) had one or more positive surrogate markers for cognitive impairment. The surrogate markers used were subjective complaints, a new onset of a psychiatric diagnosis post diagnosis with HIV, neurological complications and radiological evidence of atrophy. Multivariate analysis using logistic regression showed significant relationships only with gender and year of diagnosis. This figure is lower than reported international prevalence rates of cognitive impairment and demonstrates that surrogate markers are no match for structured cognitive screening. We have since commenced structured prospective screening to obtain a true prevalence of cognitive impairment in this population.

Abstract
Boceprevir (SCH 503034), 1, a novel HCV NS3 serine protease inhibitor discovered in our laboratories, is currently undergoing phase III clinical trials. Detailed investigations toward a second generation protease inhibitor culminated in the discovery of narlaprevir (SCH 900518), 37, with improved potency (∼10-fold over 1), pharmacokinetic profile and physicochemical characteristics, currently in phase II human trials. Exploration of synthetic sequence for preparation of 37 resulted in a route that required no silica gel purification for the entire synthesis.

Abstract
Sleep disturbances are common in Parkinson's disease (PD). Actigraphy has emerged as an alternative to polysomnography to measure sleep, raising the question of its ability to capture sleep quality in PD patients. Our aim was to compare self-report data with actigraphic data. Thirty non-demented individuals with PD and 14 normal control participants (NC) were included. Sleep was measured using 24-h wrist actigraphy over a seven day period, during which time participants kept a sleep diary. Subjective sleep and arousal questionnaires included the Parkinson's Disease Sleep Scale and Epworth Sleepiness Scale. Patients with PD presented with more sleep problems than NC. In NC, none of the actigraphic sleep variables were related to any of the self-report measures of sleep. In PD, scores on subjective sleep measures correlated with actigraphy-derived estimates of sleep quality. Our results suggest that actigraphy is an appropriate method of measuring sleep quality in PD.

Abstract
The use of laser Doppler perfusion imaging (LDPI) and laser speckle perfusion imaging (LSPI) is well known in the noninvasive investigation of microcirculatory blood flow. This work compares the two techniques with the recently developed tissue viability (TiVi) imaging system, which is proposed as a useful tool to quantify red blood cell concentration in microcirculation. Three systems are evaluated with common skin tests such as the use of vasodilating and vasoconstricting drugs (methlynicotinate and clobetasol, respectively) and a reactive hyperaemia maneuver (using a sphygmomanometer). The devices investigated are the laser Doppler line scanner (LDLS), the laser speckle perfusion imager (FLPI)-both from Moor Instruments (Axminster, United Kingdom)-and the TiVi imaging system (WheelsBridge AB, Linkoping, Sweden). Both imaging and point scanning by the devices are used to quantify the provoked reactions. Perfusion images of vasodilatation and vasoconstriction are acquired with both LDLS and FLPI, while TiVi images are acquired with the TiVi imager. Time acquisitions of an averaged region of interest are acquired for temporal studies such as the reactive hyperaemia. In contrast to the change in perfusion over time with pressure, the TiVi imager shows a different response due its measurement of blood concentration rather than perfusion. The responses can be explained by physiological understanding. Although the three devices sample different compartments of tissue, and output essentially different variables, comparisons can be seen between the three systems. The LDLS system proves to be suited to measurement of perfusion in deeper vessels, while FLPI and TiVi showed sensitivity to more superficial nutritional supply. LDLS and FLPI are insensitive to the action of the vasoconstrictor, while TiVi shows the clear boundaries of the reaction. Assessment of the resolution, penetration depth, and acquisition rate of each instrument show complimentary features that should be taken into account when choosing a system for a particular clinical measurement.
