Is there a link between previous exposure to sport injury psychology education and UK sport injury rehabilitation professionals' attitudes and behaviour towards sport psychology?

Objectives: The use of sport psychology strategies during sport injury rehabilitation can lead to several positive outcomes such as improved adherence and self-efficacy. The purpose of this study was to compare the sport psychology related attitudes and behaviours of UK sport injury rehabilitation professionals (SIRPs) who had studied the psychological aspects of sport injury to those who had not. Participants and design: Ninety-four SIRPs (54 physiotherapists and 40 sports therapists with a mean of 9.22 years' experience of working in sport) completed an online survey and were grouped according to their level of previous exposure to sport injury psychology education at an undergraduate/postgraduate level. Analyses were undertaken to establish whether there were any differences in sport psychology related attitude (MANOVA), usage (MANOVA), and referral behaviours (chi square) between the groups. Results: The MANOVA and chi square tests conducted revealed that those who had studied the psychological aspects of sport injury reported using significantly more sport psychology in their practice and making more referrals to sport psychologists. Conclusions: It was concluded that sport injury psychology education appears to be effective in increasing the sport psychology related behaviours (use of sport psychology and referral) of SIRPs and should be integrated into professional training

The impact of a sport psychology education intervention on physiotherapists

The purpose of this study was to measure the impact of an online sport psychology education module on the attitudes and behaviours of qualified sports physiotherapists in the UK. Ninety-five sport physiotherapists studied either a sport psychology module or a control module, and their attitudes and behaviours towards sport psychology were measured prior to studying the module and at three points over a six-month period following its completion. It was found that those who had studied the sport psychology module demonstrated an improvement in their attitudes towards sport psychology immediately following its completion that was significantly higher than those who had studied the control module. Use of sport psychology also increased following the sport psychology module, with significant differences seen between the intervention and control group on the sport psychology subscale, indicating that those who had studied the sport psychology module were integrating more sport psychology techniques into their practice than those who had studied the control module. It was concluded that the online sport psychology module was effective in improving the attitudes and behaviours of UK physiotherapists and that more sport psychology education opportunities should be made available

Short-term genome stability of serial Clostridium difficile ribotype 027 isolates in an experimental gut model and recurrent human disease

Firstly, 62 isolates from 29 timepoints from three in vitro gut models, inoculated with a NAP1/027 strain. Secondly, 122 isolates from 44 patients (2–8 samples/patient) with mostly recurrent/on-going symptomatic NAP-1/027 C. difficile infection. Reference-based mapping was used to identify single nucleotide variants (SNVs).Across three gut model inductions, two with antibiotic treatment, total 137 days, only two new SNVs became established. Pre-existing minority SNVs became dominant in two models. Several SNVs were detected, only present in the minority of colonies at one/two timepoints. The median (inter-quartile range) [range] time between patients’ first and last samples was 60 (29.5–118.5) [0–561] days. Within-patient C. difficile evolution was 0.45 SNVs/called genome/year (95%CI 0.00–1.28) and within-host diversity was 0.28 SNVs/called genome (0.05–0.53). 26/28 gut model and patient SNVs were non-synonymous, affecting a range of gene targets.The consistency of whole genome sequencing data from gut model C. difficile isolates, and the high stability of genomic sequences in isolates from patients, supports the use of whole genome sequencing in detailed transmission investigations.Peer reviewe

A Middle School One-to-One Laptop Program: The Maine Experience

Over eight years ago, Maine embarked on a bold new initiative. Entitled the Maine Learning Technology Initiative (MLTI), this program funded by the State of Maine, provided all 7th and 8th grade students and their teachers with laptop computers, and provided schools and teachers with a wireless internet infrastructure, technical assistance, and professional development for integrating laptop technology into their curriculum and instruction. The first full implementation of MLTI began in the Fall of the 2002-03 academic year. At the same time the Maine commissioner of education contracted with the Maine Education Policy Research Institute (MEPRI) to conduct the ongoing evaluation of MLTI. MEPRI is a non-partisan research institute funded jointly by the Maine State Legislature and the University of Maine System. Over the past eight years the MEPRI research and evaluation team has used a mixed method approach in the evaluation of the MLTI program; an approach that uses both quantitative and qualitative techniques in collecting and analyzing research and evaluation evidence. The evidence presented in this report indicates the MLTI program has had a significant impact on curriculum, instruction, and learning in Maine’s middle schools. In the areas of curriculum and instruction, the evidence indicates many teachers have reached the tipping point in the adoption and integration of the laptop into their teaching. However, the adoption is uneven for some teachers, and in some content areas. Relatively speaking, mathematics teachers use the laptops less frequently than their colleagues in other core disciplines. Most teachers are not using the laptops as frequently in assessment as one might anticipate, and too few teachers report using the laptop in teaching 21st Century Skills

Impact of sequential surface-modification of graphene oxide on ice nucleation

Base-washed graphene-oxide which has been sequentially modified by thiol-epoxy chemistry, results in materials with ice nucleation activity. The role of hydro-philic/phobic grafts and polymers was evaluated with the most potent functioning at just 0.25 wt %. These 2-D hybrid materials may find use in cryopreservation and fundamental studies on ice formation

A caspase-3 'death-switch' in colorectal cancer cells for induced and synchronous tumor apoptosis in vitro and in vivo facilitates the development of minimally invasive cell death biomarkers

Novel anticancer drugs targeting key apoptosis regulators have been developed and are undergoing clinical trials. Pharmacodynamic biomarkers to define the optimum dose of drug that provokes tumor apoptosis are in demand; acquisition of longitudinal tumor biopsies is a significant challenge and minimally invasive biomarkers are required. Considering this, we have developed and validated a preclinical 'death-switch' model for the discovery of secreted biomarkers of tumour apoptosis using in vitro proteomics and in vivo evaluation of the novel imaging probe [ 18 F]ML-10 for non-invasive detection of apoptosis using positron emission tomography (PET). The 'death-switch' is a constitutively active mutant caspase-3 that is robustly induced by doxycycline to drive synchronous apoptosis in human colorectal cancer cells in vitro or grown as tumor xenografts. Deathswitch induction caused caspase-dependent apoptosis between 3 and 24 hours in vitro and regression of 'death-switched' xenografts occurred within 24 h correlating with the percentage of apoptotic cells in tumor and levels of an established cell death biomarker (cleaved cytokeratin-18) in the blood. We sought to define secreted biomarkers of tumor apoptosis from cultured cells using Discovery Isobaric Tag proteomics, which may provide candidates to validate in blood. Early after caspase-3 activation, levels of normally secreted proteins were decreased (e.g. Gelsolin and Midkine) and proteins including CD44 and High Mobility Group protein B1 (HMGB1) that were released into cell culture media in vitro were also identified in the bloodstream of mice bearing death-switched tumors. We also exemplify the utility of the death-switch model for the validation of apoptotic imaging probes using [ 18 F]ML-10, a PET tracer currently in clinical trials. Results showed increased tracer uptake of [ 18 F]ML-10 in tumours undergoing apoptosis, compared with matched tumour controls imaged in the same animal. Overall, the death-switch model represents a robust and versatile tool for the discovery and validation of apoptosis biomarkers. © 2013 Macmillan Publishers Limited. All rights reserved

Maternal Depression Trajectories and Child BMI in a Multi-Ethnic Sample: A Latent Growth Modeling Analysis

Background Perinatal (antenatal and postpartum) depression impacts approximately 12% of mothers. Perinatal depression can impact everyday functioning for mothers, and the relationship with, and development of, their children. The purpose of this study was to investigate depression trajectories from the antenatal period through 54-months postpartum and associations with child body mass index at 54-months postpartum. Methods This study applied latent growth modeling to the Growing Up in New Zealand study, which is a longitudinal pregnancy cohort study that provides nationally representative-level data, to investigate associations between depression at three time points (antenatal, 9-months postpartum, 54-months postpartum) and child body mass index at 54-months (n=4897). Results The average slope of depression for this sample is low and decreases over time. When child BMI was added to the model as an outcome variable, both antenatal depression (B=.25, pppχ2 (9) = 39.60, p \u3c .05, SRMR = 0.01, CFI = .99, RMSEA = 0.03, BIC=53213). Conclusions Our findings align with the Developmental Origins of Health and Disease theory and imply that both the physical and mental health of mothers during pregnancy may be important indicators of child growth and development outcomes. Early intervention directed towards women who have even mild depression scores during pregnancy may promote healthy child development outcomes. Additionally, given the heterogeneity of depressive symptoms over time seen in this study, multiple assessment periods across the postpartum period may be valuable to adequately address and support maternal mental health
