Information Needs and Preferences of Parents Considering Treatment of Child Anxiety
Authors: Mak Leanne , Walker John R. , Hiebert-Murphy Diane , Altman Gary 
Published: February 2017

ABSTRACT:

Objective:
To assess the information needs and preferences of parents who were making decisions concerning treatment for their child's anxiety.

Methods:
Ninety-three parents were recruited from hospital-based clinics, a parent group, and a public information meeting. They completed a survey about preference for decision-making involvement, information needs, and preferences concerning source and amount of information.

Results:
Most (69%) parents indicated that they prefer a collaborative decision-making role. They rated very highly the need for general information related to treatment and information related to psychosocial interventions and medication treatment. Fewer parents rated information about logistics of treatment (e.g., scheduling, cost) as highly important although this information was considered important by many parents. Direct discussions with a provider, written information, and information accessed through the internet were the most preferred sources of information. Many parents indicated a preference for substantial amounts of information about psychosocial and medication treatments.

Conclusion:
Much of the information that parents want concerning treatment is not widely available. It would be helpful to develop evidence-based brochures and web information resources that focus on answering parents' questions concerning treatment of children's anxiety.

PURPOSE:
Endurance training improves oxidative stress and vascular endothelial dysfunction in patients with chronic heart failure (CHF). However, patients with CHF and an implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy-defibrillator (CRT-D) often avoid endurance training for fear of ICD shock. Recent studies have reported that stretching exercises enhance antioxidant activity and improve vascular responses. Therefore, we aimed to assess the effects of 4 weeks of stretching exercises on oxidative stress and vascular endothelial function in patients with CHF with an ICD or CRT-D.

METHODS:
Fifty sedentary patients with CHF (78% males; mean age = 70 ± 9 years; left ventricular ejection fraction = 26% ± 8%) with an ICD or CRT-D were randomly divided into a group that performed 4 weeks of stretching exercises (stretching group) and a group that continued a sedentary lifestyle (control group). We compared the reactive hyperemia peripheral arterial tonometry (RH-PAT) index and blood parameters, such as von Willebrand factor (vWF), malondialdehyde-modified low-density lipoprotein cholesterol (MDA-LDL), reactive oxygen species (ROS), high-sensitivity C-reactive protein, pentraxin 3, and fibrinogen between the 2 groups before and after the 4-week study period.

RESULTS:
In the stretching group, a significant increase in the RH-PAT index and significant decreases in vWF, MDA-LDL, ROS, and fibrinogen concentrations were observed after the study compared with before (all P < .05). No significant changes were observed in the control group.

CONCLUSION:
Four weeks of stretching exercises improved vascular endothelial dysfunction through attenuation of oxidative stress in sedentary patients with CHF with an ICD or CRT-D.

PURPOSE:
Patients with chronic obstructive pulmonary disease (COPD) have body balance deficits, with consequent fall risk. It is possible that body sway in patients with COPD affects their ability to perform daily activities. The purpose of this study was to determine whether body balance is similar in patients with COPD and healthy persons when performing static and dynamic activities. In addition, we wanted to assess whether impairment of balance is related to the presence of falls in patients with COPD.

METHODS:
This is a cross-sectional study, in which every spirometric classification in patients with COPD (mild, moderate, severe, and very severe degrees) and age-matched healthy subjects was assessed. Subjects who were current smokers and patients who underwent physical training in the last 6 months prior to the start of the study were excluded. Static balance was assessed by computerized posturography and dynamic body balance using the Berg Balance Scale.

RESULTS:
Ninety-three patients with COPD and 39 healthy persons were evaluated. Mean age was 67.3 (10.8) and 65.1 (9.7) years and mean forced expiratory volume in 1 second (FEV1) was 50.4 (19.0) and 89.2 (23.6) for patients with COPD and healthy individuals, respectively. The impairment of body balance was higher for the group of patients with COPD (P = .0005). Patients with greater impairment in body balance had greater incidence of falls, and body balance was more affected with age in patients with COPD than in healthy persons.

CONCLUSION:
Impairment of body balance is more frequent in patients with COPD than in healthy persons while performing dynamic activities, and a greater incidence of falls activities was also found for this group.
Environmental market factors associated with electronic health record adoption among cancer hospitals
Authors: Tarver Will L. , Menachemi Nir 
Published: February 2017

Background:
Although recent literature has explored the relationship between various environmental market characteristics and the adoption of electronic health records (EHRs) among general, acute care hospitals, no such research currently exists for specialty hospitals, including those providing cancer care.

Purpose:
The aim of the study was to examine the relationship between market characteristics and the adoption of EHRs among Commission on Cancer (CoC)-accredited hospitals.

Methods/Approach:
Secondary data on EHR adoption combined with hospital and environmental market characteristics were analyzed using logistic regression. Using the resource dependence theory, we examined how measures of munificence, complexity, and dynamism are related to the adoption of EHRs among CoC-accredited hospitals and, separately, hospitals not CoC-accredited.

Findings:
In a sample of 2,670 hospitals, 141 (0.05%) were academic-based CoC-accredited hospitals and 562 (21%) were community-based CoC-accredited hospitals. Measures of munificence such as cancer incidence rates (OR = 0.99, CI [0.99, 1.00], p = .020) and percentage population aged 65+ (OR = 0.99, CI [0.99, 1.00], p = .001) were negatively associated with basic EHR adoption, whereas urban location was positively associated with comprehensive EHR adoption (OR = 3.07, CI [0.89, 10.61], p = .076) for community-based CoC-accredited hospitals. Measures of complexity such as hospitals in areas with less competition were less likely to adopt a basic EHR (OR = 0.33, CI [0.19, 0.96], p = .005), whereas Medicare Managed Care penetration was positively associated with comprehensive EHR adoption (OR = 1.02, CI [1.00, 1.05], p = .070) among community-based CoC-accredited hospitals. Lastly, dynamism, measured as population change, was negatively associated with the adoption of comprehensive EHRs (OR = 0.99, CI [0.99, 1.00], p = .070) among academic-based CoC-accredited hospitals.

Practice implications:
A greater understanding of the environment’s relationship to health information technology adoption in cancer hospitals will help stakeholders in these institutions make informed strategic decisions about information technology investments guided by their facilities’ respective environmental factors. The results of this study may also be useful to hospital chief information officers and chief executive officers seeking to either improve their quality of care or achieve and maintain accreditation in providing cancer care.

Abstract
Although widely used, the Hamilton Rating Scale for Depression (HRSD) and Hamilton Anxiety Rating Scale (HARS) discriminate poorly between depression and anxiety. To address this problem, Riskind, Beck, Brown, and Steer (J Nerv Ment Dis. 175:474–479, 1987) created the Reconstructed Hamilton Scales by reconfiguring HRSD and HARS items into modified scales. To further analyze the reconstructed scales, we examined their factor structure and criterion-related validity in a sample of patients with major depressive disorder and no comorbid anxiety disorders (n = 215) or with panic disorder and no comorbid mood disorders (n = 149). Factor analysis results were largely consistent with those of Riskind et al. The correlation between the new reconstructed scales was small. Compared with the original scales, the new reconstructed scales correlated more strongly with diagnosis in the expected direction. The findings recommend the use of the reconstructed HRSD over the original HRSD but highlight problems with the criterion-related validity of the original and reconstructed HARS.

ABSTRACTPurposeTo validate the Perceived Stress Scale (PSS) in patients with age-related macular degeneration (AMD) using Rasch analysis.MethodsStudy participants with AMD were recruited from the retina service of the Department of Ophthalmology at the Ohio State University during clinical visits for treatment or observation. Visual acuity with habitual distance correction was assessed. A 10-item version of the PSS was administered in large print or by reading the items to the patient. Rasch analysis was used to investigate the measurement properties of the PSS, including fit to the model, ability to separate between people with different levels of perceived stress, category response structure performance, and unidimensionality.ResultsA total of 137 patients with a diagnosis of AMD were enrolled. The mean (±SD) age of participants was 82 ± 9 years. Fifty-four percent were female. Median Early Treatment of Diabetic Retinopathy Study (ETDRS) visual acuity of the better eye was 65 letters (Snellen 20/50), with a range of approximately 20/800 to 20/15. Forty-seven percent of participants were receiving an anti-VEGF injection on the day of the study visit. The response category structure was appropriate. One item, “How often have you felt confident in your ability to handle your personal problems?” was removed due to poor fit statistics. The remaining nine items showed good fit to the model, acceptable measurement precision as assessed by the Rasch person separation statistic, and unidimensionality. There was some evidence of differential item functioning by age and visual acuity.ConclusionsThe Perceived Stress Scale demonstrated acceptable measurement properties and may be useful for the measurement of perceived stress in patients with AMD.

Published: February 2017

Objective
The current study demonstrated the potential use of calcineurin inhibitor (CNI) in combination therapy for interstitial lung disease (ILD) complicated with dermatomyositis (DM) and polymyositis (PM).

Methods
Thirty DM/PM patients with ILD were enrolled in this study. Continuous intravenous administration of cyclosporine A (IV-CsA) was simultaneously started with corticosteroid in patients presenting more than two respiratory distress factors as follows: <70 mmHg of PaO2, percentage of vital capacity <70%, and/or exertional dyspnea. Other patients took CNI orally with corticosteroid. When a patient presented exacerbation of ILD, intravenous cyclophosphamide pulse therapy (IVCY) was additionally administrated. Clinical outcomes were compared with those of 21 patients who had been previously treated in our hospital before starting this study, as the historical comparison group.

Results
Seven patients underwent IV-CsA, maintaining the drug concentration in blood between 300 and 350 ng/mL, and six of them had favorable outcomes without any adverse events. Eight out of the 30 patients additionally required IVCY. Meanwhile, the frequency of death ascribable to respiratory failure was 6.7%, which was significantly lower than that of the historical comparison group (P = 0.043). Furthermore, longer survival free from exacerbation and severe adverse event was significantly shown (P = 0.029).

Conclusions
For repressing the activity of ILD in DM/PM patients, stabilizing the blood concentration of CNI immediately is a reasonable treatment as well as initiating immunosuppressive therapy in the early phase of the illness. IV-CsA may be a useful option for achieving this purpose in patients with severe ILD.

Published: February 2017

Objective
The aim of this study was to develop a patient-reported outcome measure specific for systemic lupus erythematosus (SLE) to assess patient satisfaction with treatment, treatment options, and medical care.

Methods
Patients with SLE were recruited from four US rheumatology practices. Concept elicitation interviews identified aspects that patients considered important and relevant regarding satisfaction with treatment and medical care. Concept elicitation interviews and clinical input were used to draft the Lupus Satisfaction Questionnaire (LSQ). A second cohort of patients with SLE participated in combined concept elicitation/cognitive debriefing interviews, after which the LSQ was revised.

Results
Fourteen patients completed concept elicitation interviews: 93% were female, 57% were white, and 85% had moderate/severe SLE. Current treatments included hydroxychloroquine (93%), steroids (79%), and belimumab (57%), and 43% were biologic naive. Patients were generally satisfied with their treatment and medical care; however, they were dissatisfied with treatment adverse effects and the number of available treatment options. Cognitive debriefing interviews (n = 8) demonstrated that the LSQ was comprehensive, clear, and relevant; therefore, only minor revisions were made to the questionnaire. The LSQ assesses satisfaction with current SLE treatments (25 items), medical care (11 items), and insurance coverage (3 items). The draft LSQ was evaluated in 195 adults with SLE. Fifty-eight percent of patients reported that they were “somewhat satisfied” with their SLE treatment.

Conclusions
The LSQ has been developed to assess treatment satisfaction among patients with SLE. Following further testing to support its validity and reliability, it will provide a useful tool to facilitate assessment of satisfaction with treatments for SLE and help inform treatment decisions.
Repressing Integrase attachment site operation with CRISPR-Cas9 inE. coli
Authors: Shur Andrey , Murray Richard M. 
Published: February 2017

AbstractSerine integrases are bacteriophage proteins responsible for integrating the phage genome into that of the host. Synthetic biologists have co-opted these proteins into useful tools for permanent DNA logic, utilizing their specific DNA recombination abilities to build synthetic cell differentiation and genetic memory systems. Each integrase has a specific pair of DNA sequences (attP/attB sites) that it recombines, but multiple identical sites can result in unpredictable recombination. We have developed a way to control integrase activity on identical attP/attB sites by using catalytically dead Cas9 (dCas9) as a programmable binding protein that can compete with integrase for binding to specific attachment sites. Utilizing a plasmid that contains two identical Bxb1 attP sites, integration can be repressed up to 8 fold at either one of the two attP sites when guide RNA and dCas9 are present. Guide RNA sequences that bind specifically to attB, or either of two attP sites, have been developed. Future goals are to utilize this technology to construct larger and more complex integrase logic circuits.

Published: February 2017

AbstractNumerous brain lesion and fMRI studies have linked individual differences in executive abilities and fluid intelligence to brain regions of the fronto-parietal “multiple-demand” (MD) network. Yet, fMRI studies have yielded conflicting evidence as to whether better executive abilities are associated with stronger or weaker MD activations and whether this relationship is restricted to the MD network. Here, in a large-sample (n=216) fMRI investigation, we found that stronger activity in MD regions – functionally defined in individual participants – was robustly associated with more accurate and faster responses on a spatial working memory task performed in the scanner, as well as fluid intelligence measured independently (n=114). In line with some prior claims about a relationship between language and fluid intelligence, we also found a weak association between activity in the brain regions of the left fronto-temporal language network during an independent passive reading task, and performance on the working memory task. However, controlling for the level of MD activity abolished this relationship, whereas the MD activity-behavior association remained highly reliable after controlling for the level of activity in the language network. Finally, we demonstrate how unreliable MD activity measures, coupled with small sample sizes, could falsely lead to the opposite, negative, association that has been reported in some prior studies. Taken together, these results demonstrate that a core component of individual differences variance in executive abilities and fluid intelligence is selectively and robustly positively associated with the level of activity in the MD network, a result that aligns well with lesion studies.

Published: February 2017

AbstractBackgroundAberrant expression of miRNAs was a critical element in the pathogenesis of inflammatory bowel disease (IBD). This study aimed to explore the involvement and mechanism of miR-126 in IBD.MethodsIn this study, the endogenous expressions of miR-126, S1PR2 and S1P in the pathological tissues of patients with IBD were detected using qRT-PCR and western blot assay, respectively. The luciferase reporter gene assay was performed to confirm the targeting regulatory relation between miR-126 and S1PR2. The transendothelial electrical resistance assay was used to measured the value of TEER.ResultsThe expressions of miR-126, S1PR2 and S1P in the pathological tissues of IBD patients were significantly higher than that of the control group. Moreover, miR-126 overexpression contributed to intestinal mucosal barrier dysfunctionin vitro.S1PR2 was a direct target of miR-126, and S1PR2 expression was negatively regulated by miR-126 in Caco-2 cells. However, S1PR2 activated by S1P had the protection effect for the integrity and permeability of intestinal mucosal barrier via a PI3K/Akt dependent mechanism. MiR-126 silencing possessed obvious protective effects on the intestinal barrier function, but these effects could be reversed by JTE-013 or LY294002.ConclusionMiR-126 down-regulated S1PR2 and then prevented the activation of PI3K/AKT signaling pathway, which ultimately could damage intestinal mucosal barrier function.
ChromVAR: Inferring transcription factor variation from single-cell epigenomic data

Published: February 2017

AbstractSingle cell ATAC-seq (scATAC) yields sparse data that makes application of conventional computational approaches for data analysis challenging or impossible. We developed chromVAR, an R package for analyzing sparse chromatin accessibility data by estimating the gain or loss of accessibility within sets of peaks sharing the same motif or annotation while controlling for known technical biases. chromVAR enables accurate clustering of scATAC-seq profiles and enables characterization of known, or thede novoidentification of novel, sequence motifs associated with variation in chromatin accessibility across single cells or other sparse epigenomic data sets.

AbstractMonitoring changes in influenza A virus genomes is crucial to understand its rapid evolution and adaptation to changing conditions e.g. establishment within novel host species. Selective sweeps represent a rapid mode of adaptation and are typically observed in human influenza A viruses. We describe Sweep Dynamics (SD) plots, a computational method combining phylogenetic algorithms with statistical techniques to characterize the molecular adaptation of rapidly evolving viruses from longitudinal sequence data. To our knowledge, it is the first method that identifies selective sweeps, the time periods in which these occurred and associated changes providing a selective advantage to the virus. We studied the past genome-wide adaptation of the 2009 pandemic H1N1 influenza A (pH1N1) and seasonal H3N2 influenza A (sH3N2) viruses. The pH1N1 influenza virus showed simultaneous amino acid changes in various proteins, particularly in seasons of high pH1N1 activity. Partially, these changes resulted in functional alterations facilitating sustained human-to-human transmission. In the evolution of sH3N2 influenza viruses, we detected changes characterizing vaccine strains, which were occasionally revealed in selective sweeps one season prior to the WHO recommendation. Taken together, SD plots allow monitoring and characterizing the adaptive evolution of influenza A viruses by identifying selective sweeps and their associated signatures.
