Evidence-Based Practice Confidence and Behavior Throughout the Curriculum of Four Physical Therapy Education Programs: A Longitudinal Study
Background
Evidence-based practice (EBP) is a foundational process taught in health professional education, yet it is unclear when EBP confidence and skills are obtained. Increases in EBP confidence and behaviors from the start of physical therapy programs to post graduation have been reported in studies that evaluated a single program or used non-valid questionnaires. This study aimed to describe changes in EBP confidence and behavior using validated questionnaires of students from four physical therapy education programs throughout their curriculum and one year post graduation. Methods
One hundred and eighty-one students from a potential pool of 269 (67.3%) consented to participate. Students completed the Evidence-Based Practice Confidence (EPIC) Scale and the Evidence-Based Practice Implementation Scale (EBPIS) at 6 timepoints: start of the program, prior to first clinical experience, after first clinical experience, at the end of classroom instruction, graduation, and one year post. Medians (Mdn) and 25th and 75th percentiles (P25, P75) were calculated for 42 (23.2%) students with complete data across all timepoints. Change between timepoints was assessed using Friedman’s test and Wilcoxon signed rank test with a Bonferroni correction for post hoc analysis. Results
There were significant changes in EPIC scores (p \u3c 0.001) from enrollment (Mdn 50.0, P25, P75 35.5, 65.9) to prior to first clinical experience (Mdn 65.5, P25, P75 57.3, 72.5) and after the first clinical experience (Mdn 67.3, P25, P75, 58.9, 73.2) to the end of classroom instruction (Mdn 78.6, P25, P75, 72.0, 84.1). Significant increases on the EBPIS (p \u3c 0.01) were only seen from after the first year of training (Mdn 15, P25, P75, 10.0, 22.5) to end of the first clinical experience (Mdn 21.5, P25, P75 12.0, 32.0). Conclusions
EBP confidence increased significantly after classroom instruction but remained the same after clinical experiences and at one year post graduation. EBP behavior significantly increased only after the first clinical experience and remained the same through graduation. Confidence and behavior scores were higher than were previously reported in practicing professionals. Ongoing assessment of EBP confidence and behavior may help instructors build appropriate curricula to achieve their outlined EBP objectives
Relationship between Occupational and Physical Therapist Students’ Belongingness and Perceived Competence in the Clinic using the Ascent to Competence Scale
Clinical education experiences (CEEs) serve an essential role in physical therapist (PT) and occupational therapist (OT) student development. The Ascent to Competence Scale (ACS) measures valuable attributes of belongingness, competence, and welcoming associated with CEE placement. The purpose of this study was to examine the relationship between PT and OT students’ belongingness and perceived competence during CEE using the ACS. A survey consisting of 35 questions from the ACS measuring students’ feelings of belongingness and perceived competence in the clinic was administered to PT and OT students from 7 Midwest universities. Respondents rated statements using a 5-point Likert-type scale (“never true” to “always true”). Ascent to Competence items were aggregated to develop belongingness and perceived competence constructs. One hundred nineteen (67.2% PT, 32.8% OT) of 509 (23.4% response) eligible students completed the survey. Results of a linear regression analysis showed belongingness in the clinical environment significantly predicted perceived competence measures, F(1, 117) = 182.389; P = r2 = .609, y(comp) = .721(Xbel) + 1.249. Cumulative weeks in CEE and practice environment did not contribute to the predictive model. The analysis lends further support to the role that belongingness plays in advancing perceived competence during the CEE. The results suggest that supportive clinical education environments can positively impact student learning by promoting a sense of belongingness among student therapists
Adsorption models of hybridization and post-hybridisation behaviour on oligonucleotide microarrays
Analysis of data from an Affymetrix Latin Square spike-in experiment
indicates that measured fluorescence intensities of features on an
oligonucleotide microarray are related to spike-in RNA target concentrations
via a hyperbolic response function, generally identified as a Langmuir
adsorption isotherm. Furthermore the asymptotic signal at high spike-in
concentrations is almost invariably lower for a mismatch feature than for its
partner perfect match feature. We survey a number of theoretical adsorption
models of hybridization at the microarray surface and find that in general they
are unable to explain the differing saturation responses of perfect and
mismatch features. On the other hand, we find that a simple and consistent
explanation can be found in a model in which equilibrium hybridization followed
by partial dissociation of duplexes during the post-hybridization washing
phase.Comment: 26 pages, 6 figures, some rearrangement of sections and some

Adenovirus Type 7 Genomic-Type Variant, New York City, 1999
An outbreak of respiratory illness occurred in a long-term care facility in New York City. Investigation of the outbreak identified confirmed or suspected adenoviral infection in 84% of the residents from October 19 to December 18, 1999. Further identification by type-specific neutralization and restriction analysis identified a new genomic variant of adenovirus type 7

Dyclonine rescues frataxin deficiency in animal models and buccal cells of patients with Friedreich's ataxia.
Inherited deficiency in the mitochondrial protein frataxin (FXN) causes the rare disease Friedreich's ataxia (FA), for which there is no successful treatment. We identified a redox deficiency in FA cells and used this to model the disease. We screened a 1600-compound library to identify existing drugs, which could be of therapeutic benefit. We identified the topical anesthetic dyclonine as protective. Dyclonine increased FXN transcript and FXN protein dose-dependently in FA cells and brains of animal models. Dyclonine also rescued FXN-dependent enzyme deficiencies in the iron-sulfur enzymes, aconitase and succinate dehydrogenase. Dyclonine induces the Nrf2 [nuclear factor (erythroid-derived 2)-like 2] transcription factor, which we show binds an upstream response element in the FXN locus. Additionally, dyclonine also inhibited the activity of histone methyltransferase G9a, known to methylate histone H3K9 to silence FA chromatin. Chronic dosing in a FA mouse model prevented a performance decline in balance beam studies. A human clinical proof-of-concept study was completed in eight FA patients dosed twice daily using a 1% dyclonine rinse for 1 week. Six of the eight patients showed an increase in buccal cell FXN levels, and fold induction was significantly correlated with disease severity. Dyclonine represents a novel therapeutic strategy that can potentially be repurposed for the treatment of FA
Human Proteome Project Mass Spectrometry Data Interpretation Guidelines 3.0
The Human Proteome Organization’s (HUPO) Human Proteome Project (HPP) developed Mass Spectrometry (MS) Data Interpretation Guidelines that have been applied since 2016. These guidelines have helped ensure that the emerging draft of the complete human proteome is highly accurate and with low numbers of false-positive protein identifications. Here, we describe an update to these guidelines based on consensus-reaching discussions with the wider HPP community over the past year. The revised 3.0 guidelines address several major and minor identified gaps. We have added guidelines for emerging data independent acquisition (DIA) MS workflows and for use of the new Universal Spectrum Identifier (USI) system being developed by the HUPO Proteomics Standards Initiative (PSI). In addition, we discuss updates to the standard HPP pipeline for collecting MS evidence for all proteins in the HPP, including refinements to minimum evidence. We present a new plan for incorporating MassIVE-KB into the HPP pipeline for the next (HPP 2020) cycle in order to obtain more comprehensive coverage of public MS data sets. The main checklist has been reorganized under headings and subitems, and related guidelines have been grouped. In sum, Version 2.1 of the HPP MS Data Interpretation Guidelines has served well, and this timely update to version 3.0 will aid the HPP as it approaches its goal of collecting and curating MS evidence of translation and expression for all predicted ∼20 000 human proteins encoded by the human genome.This work was funded in part by the National Institutes of Health grants R01GM087221 (EWD/RLM), R24GM127667 (EWD), U54EB020406 (EWD), R01HL133135 (RLM), U19AG02312 (RLM), U54ES017885 (GSO), U24CA210967-01 (GSO), R01LM013115 (NB) and P41GM103484 (NB); National Science Foundation grants ABI-1759980 (NB), DBI-1933311 (EWD), and IOS-1922871 (EWD); Canadian Institutes of Health Research 148408 (CMO); Korean Ministry of Health and Welfare HI13C2098 (YKP); French Ministry of Higher Education, Research and Innovation, ProFI project, ANR-10-INBS-08 (YV); also in part by the National Eye Institute (NEI), National Human Genome Research Institute (NHGRI), National Heart, Lung, and Blood Institute (NHLBI), National Institute of Allergy and Infectious Diseases (NIAID), National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), National Institute of General Medical Sciences (NIGMS), and National Institute of Mental Health (NIMH) of the National Institutes of Health under Award Number U24HG007822 (SO) (the content is solely the responsibility of the authors and does not necessarily represent the official views of the National Institutes of Health)
