Abstract
INTRODUCTION The Rehabilitation EnAblement in CHronic Heart Failure in patients with Heart Failure (HF) with preserved ejection fraction (REACH-HFpEF) pilot trial is part of a research programme designed to develop and evaluate a facilitated, home-based, self-help rehabilitation intervention to improve self-care and quality of life (QoL) in heart failure patients and their caregivers. We will assess the feasibility of a definitive trial of the REACH-HF intervention in patients with HFpEF and their caregivers. The impact of the REACH-HF intervention on echocardiographic outcomes and bloodborne biomarkers will also be assessed. METHODS AND ANALYSIS A single-centre parallel two-group randomised controlled trial (RCT) with 1:1 individual allocation to the REACH-HF intervention plus usual care (intervention) or usual care alone (control) in 50 HFpEF patients and their caregivers. The REACH-HF intervention comprises a REACH-HF manual with supplementary tools, delivered by trained facilitators over 12 weeks. A mixed methods approach will be used to assess estimation of recruitment and retention rates; fidelity of REACH-HF manual delivery; identification of barriers to participation and adherence to the intervention and study protocol; feasibility of data collection and outcome burden. We will assess the variance in study outcomes to inform a definitive study sample size and assess methods for the collection of resource use and intervention delivery cost data to develop the cost-effectiveness analyses framework for any future trial. Patient outcomes collected at baseline, 4 and 6 months include QoL, psychological well-being, exercise capacity, physical activity and HF-related hospitalisation. Caregiver outcomes will also be assessed, and a substudy will evaluate impact of the REACH-HF manual on resting global cardiovascular function and bloodborne biomarkers in HFpEF patients. ETHICS AND DISSEMINATION The study is approved by the East of Scotland Research Ethics Service (Ref: 15/ES/0036). Findings will be disseminated via journals and presentations to clinicians, commissioners and service users. TRIAL REGISTRATION NUMBER ISRCTN78539530; Pre-results .

Abstract
Decreased blood dendritic cell precursors (DCP) count is linked with atherosclerotic disease, while reduction of circulating DCP is also seen in patients with chronic kidney disease (CKD). As poor vitamin D status could be linked to a compromised innate immune response, we hypothesized that vitamin D status might be involved in the decrease in circulating DCP in CKD. Moreover, the potential role of inflammation was considered. Circulating myeloid (mDCP), plasmacytoid (pDCP) and total DCP (tDCP) were analysed using flow cytometry in 287 patients with CKD stage 3. Serum 25(OH)D and 1,25(OH)2D levels were measured using enzyme-linked immunosorbent assays (ELISA), interleukin (IL)-6, IL-10 and tumour necrosis factor (TNF)-α using cytometric bead array, C-reactive protein (CRP) using a high-sensitivity (hs) ELISA. Contrary to our hypothesis, there was no association between vitamin D levels and DCP, although their number was decreased significantly in CKD (P < 0·001). Instead, mDCP (r = -0·211) and tDCP (r = -0·188,) were associated slightly negatively with hsCRP but positively with the estimated glomerular filtration rate (eGFR, r = 0·314 for tDCP). According to multivariate linear regression, only higher hsCRP concentration and the presence of diabetes mellitus had a significant negative influence on DCP count (P < 0·03, respectively) but not vitamin D, age and eGFR. A significant impact of vitamin D on the reduction of circulating DCP in CKD 3 patients can be neglected. Instead, inflammation as a common phenomenon in CKD and diabetes mellitus had the main influence on the decrease in DCP. Thus, a potential role for DCP as a sensitive marker of inflammation and cardiovascular risk should be elucidated in future studies.

Optimising self-care support for people with heart failure and their caregivers: development of the Rehabilitation Enablement in Chronic Heart Failure (REACH-HF) intervention using intervention mapping. Pilot Feasibility Stud 2016; 2:37. [PMID: 27965855 PMCID: PMC5153822 DOI: 10.1186/s40814-016-0075-x] [Citation(s) in RCA: 46] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2015] [Accepted: 06/30/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND We aimed to establish the support needs of people with heart failure and their caregivers and develop an intervention to improve their health-related quality of life. METHODS We used intervention mapping to guide the development of our intervention. We identified "targets for change" by synthesising research evidence and international guidelines and consulting with patients, caregivers and health service providers. We then used behaviour change theory, expert opinion and a taxonomy of behaviour change techniques, to identify barriers to and facilitators of change and to match intervention strategies to each target. A patient and public involvement group helped to identify patient and caregiver needs, refine the intervention objectives and strategies and deliver training to the intervention facilitators. A feasibility study (ISRCTN25032672) involving 23 patients, 12 caregivers and seven trained facilitators at four sites assessed the feasibility and acceptability of the intervention and quality of delivery and generated ideas to help refine the intervention. RESULTS The Rehabilitation Enablement in Chronic Heart Failure (REACH-HF) intervention is a comprehensive self-care support programme comprising the "Heart Failure Manual", a choice of two exercise programmes for patients, a "Family and Friends Resource" for caregivers, a "Progress Tracker" tool and a facilitator training course. The main targets for change are engaging in exercise training, monitoring for symptom deterioration, managing stress and anxiety, managing medications and understanding heart failure. Secondary targets include managing low mood and smoking cessation. The intervention is facilitated by trained healthcare professionals with specialist cardiac experience over 12 weeks, via home and telephone contacts. The feasibility study found high levels of satisfaction and engagement with the intervention from facilitators, patients and caregivers. Intervention fidelity analysis and stakeholder feedback suggested that there was room for improvement in several areas, especially in terms of addressing caregivers' needs. The REACH-HF materials were revised accordingly. CONCLUSIONS We have developed a comprehensive, evidence-informed, theoretically driven self-care and rehabilitation intervention that is grounded in the needs of patients and caregivers. A randomised controlled trial is underway to assess the effectiveness and cost-effectiveness of the REACH-HF intervention in people with heart failure and their caregivers.

Abstract
Abstract
BACKGROUND: First Nations (FN) youth in Canada have the highest rates of pain-related conditions (ear, dental, headaches) yet may be least likely to be treated for them. Untreated pain has an arresting impact on growth and development and is detrimental to the achievement of life goals. In recent research conducted by the Aboriginal Children’s Hurt & Healing Initiative (ACHH), community participants reported that First Nation children are stoic and are reluctant to talk about their pain (Latimer & Rudderham, 2013). Clinicians are trained to assess pain based on overt signs of expression (cry, facial grimace, ability to describe) however if you do not present your pain this way it may reduce the chance of proper assessment and treatment.
OBJECTIVES: Using a Two-Eyed Seeing qualitative perspective (best of Indigenous and Western knowledge) the purpose of this research was to provide FN youth with the method of art making to determine how they express their pain.
DESIGN/METHODS: Youth from four FN communities, in three Maritime Provinces were invited to participate in art workshops facilitated by internationally renowned Mi’kmaq artist Alan Syliboy. The workshop began with a conversation circle about pain experiences and then proceeded to the art making. A FN documentary cinematographer captured the workshops and the results are documented in art and film. Three team members independently themed the data using thematic analysis and the inter-rater reliability was >85%.
RESULTS: 39 youth aged 10-18 years participated in 4 community-based conversation and art sessions. The themes for the sessions were themed using the four dimensions of the Medicine Wheel. While the overwhelming theme discussed in the conversation sessions was physical pain, when provided the nonverbal, art mode of expression, the youth painted emotional pain more frequently than physical, spiritual and mental pain. There was overlap between the four themes but 70% of the artwork prominently illustrated emotional pain with 54% overlapping with physical, 30% mental and 31% spiritual.
CONCLUSION: These results present a more complicated issue regarding the integration of the different types of pain, intertwined together. The finding that when asked-youth primarily discussed physical pain but given the opportunity, more frequently painted emotional pain may shed new light on the degree to which emotional pain is a factor for these youth. The artwork and accompanying narratives are powerful and have implications for understanding the complexity of assessing the different dimensions of pain in a culturally meaningful manner and for clinician education purposes. A sample of the artwork is attached.

Abstract
Amphetamine (AMPH) exposure leads to changes in behavior and dopamine receptor function in the prefrontal cortex (PFC). Since dopamine plays an important role in regulating GABAergic transmission in the PFC, we investigated if AMPH exposure induces long-lasting changes in dopamine's ability to modulate inhibitory transmission in the PFC as well as whether the effects of AMPH differed depending on the age of exposure. Male Sprague-Dawley rats were given saline or 3 mg/kg AMPH (i.p.) repeatedly during adolescence or adulthood and following a withdrawal period of up to 5 weeks (Experiment 1) or up to 14 weeks (Experiment 2), they were sacrificed for in vitro whole-cell recordings in layer V/VI of the medial PFC. We found that in brain slices from either adolescent- or adult-exposed rats, there was an attenuation of dopamine-induced increases in inhibitory synaptic currents in pyramidal cells. These effects did not depend on age of exposure, were mediated at least partially by a reduced sensitivity of D1 receptors in AMPH-treated rats, and were associated with an enhanced behavioral response to the drug in a separate group of rats given an AMPH challenge following the longest withdrawal period. Together, these data reveal a prolonged effect of AMPH exposure on medial PFC function that persisted for up to 14 weeks in adolescent-exposed animals. These long-lasting neurophysiological changes may be a contributing mechanism to the behavioral consequences that have been observed in those with a history of amphetamine abuse.

Abstract
INTRODUCTION The Rehabilitation EnAblement in CHronic Heart Failure (REACH-HF) trial is part of a research programme designed to develop and evaluate a health professional facilitated, home-based, self-help rehabilitation intervention to improve self-care and health-related quality of life in people with heart failure and their caregivers. The trial will assess the clinical effectiveness and cost-effectiveness of the REACH-HF intervention in patients with systolic heart failure and impact on the outcomes of their caregivers. METHODS AND ANALYSIS A parallel two group randomised controlled trial with 1:1 individual allocation to the REACH-HF intervention plus usual care (intervention group) or usual care alone (control group) in 216 patients with systolic heart failure (ejection fraction <45%) and their caregivers. The intervention comprises a self-help manual delivered by specially trained facilitators over a 12-week period. The primary outcome measure is patients' disease-specific health-related quality of life measured using the Minnesota Living with Heart Failure questionnaire at 12 months' follow-up. Secondary outcomes include survival and heart failure related hospitalisation, blood biomarkers, psychological well-being, exercise capacity, physical activity, other measures of quality of life, patient safety and the quality of life, psychological well-being and perceived burden of caregivers at 4, 6 and 12 months' follow-up. A process evaluation will assess fidelity of intervention delivery and explore potential mediators and moderators of changes in health-related quality of life in intervention and control group patients. Qualitative studies will describe patient and caregiver experiences of the intervention. An economic evaluation will estimate the cost-effectiveness of the REACH-HF intervention plus usual care versus usual care alone in patients with systolic heart failure. ETHICS AND DISSEMINATION The study is approved by the North West-Lancaster Research Ethics Committee (ref 14/NW/1351). Findings will be disseminated via journals and presentations to publicise the research to clinicians, commissioners and service users. TRIAL REGISTRATION NUMBER ISRCTN86234930; Pre-results.

Abstract
The value of diffusion-weighted magnet resonance imaging (DWI-MRI) has been demonstrated for an ever growing range of clinical indications. DWI is sensitive to the diffusion of water molecules and probes their random displacement within tissue. DWI provides both qualitative and quantitative information on tissue characteristics, e.g. tissue cellularity. This review provides an overview of diffusion-weighted imaging and its emerging applications in ophthalmology. The basic physics and technical foundations of DWI are introduced. The emerging applications of DWI are surveyed, particularly in diseases of the eye, orbit and optical nerve.

Abstract
BACKGROUND/OBJECTIVES Low birth weight (LBW), defined as the body weight at birth of less than 2500 g, is a major public health problem in Bangladesh, where 37% of the babies are born with LBW. The objective of this study is to see the impact of nutrition education on growth of LBW babies with early initiation and exclusive breastfeeding compared to control group. SUBJECTS/METHODS A total of 184 LBW babies and their mothers who attended the Maternal Care and Health Training Institute and Dhaka Medical College Hospital were randomly allocated to either intervention or control group. Enrollment of the study population started in May 2008 and was completed in October 2008. Nutrition education was given to mothers twice weekly for 2 months, on initiation of breastfeeding within 1 h, exclusive breastfeeding and increasing their dietary intake. Nutritional status of LBW babies was assessed for length and weight every 2 weeks. Data were analyzed using SPSS/Window's version 12. Comparison of mean of data was done using standard Student's t-test. RESULTS Mean initial body weight and length of LBW babies were similar in both groups (2261±198 g vs 2241±244 g, P=0.535 and 43.0±1.3 cm vs 43.0±1.7 cm, P=0.77). Body weight and length of the LBW babies after 2 months increased significantly (3620±229 g vs 3315±301 g, P<0.001 and 50.2±1.3 cm vs 48.7±1.6 cm, P<0.001). It was found that the intervention group suffered less from respiratory illness compared with the control group (39% vs 66%, P<0.001). The rate of early initiation of breastfeeding was also significantly higher with nutrition intervention (59.8% vs 37.2%, P<0.001). Exclusive breastfeeding rate was significantly higher in intervention group (59.8% vs 37%, P=0.003). CONCLUSIONS The present study showed that weight and length gain of LBW babies significantly increased by breastfeeding and nutrition education. Therefore, nutrition education on breastfeeding proves to be a strong tool to reduce the high risk of malnutrition and mortality of the LBW babies.

Abstract
BACKGROUND Numerous studies have shown differences in pain perception between men and women, which may affect pain management strategies. AIM Our primary aim was to investigate whether there are gender-based differences in pain management in patients admitted to our emergency department with acute, non-specific abdominal pain (NSAP). Our secondary aim was to evaluate if other factors influence administration of analgesia for patients admitted with NSAP. METHODS From June 2007 to June 2008, we carried out a retrospective, gender-based, frequency-matched control study with 150 patients (75 consecutive men and 75 women) who presented with NSAP at our emergency department. Pain was documented using a numerical rating scale ('0' no pain, '10' most severe pain). A multinomial regression model was used to assess factors that might influence pain management. RESULTS No statistically significant difference was seen between men and women with respect to pain management (P= 0.085). Younger patients were, however, more likely to receive weaker (P= 0.011) and fewer analgesics (P < 0.001). Patients with previous abdominal surgery (P= 0.012), known chronic pain conditions (P= 0.029) or relevant comorbidities (P= 0.048) received stronger analgesia. Nationality (P= 0.244), employment status (P= 0.988), time of admission (P= 0.487) and known psychiatric illness (P= 0.579) did not influence pain management. CONCLUSIONS No statistically significant gender-dependent differences in pain management were observed. However, younger patients received less potent analgesic treatment. There is no reason for certain groups to receive suboptimal treatment, and greater efforts should be made to offer consistent treatment to all patients.

Abstract
GM1 gangliosidosis manifests with progressive psychomotor deterioration and dysostosis of infantile, juvenile, or adult onset, caused by alterations in the structural gene coding for lysosomal acid beta-galactosidase (GLB1). In addition, allelic variants of this gene can result in Morquio B disease (MBD), a phenotype with dysostosis multiplex and entire lack of neurologic involvement. More than 100 sequence alterations in the GLB1 gene have been identified so far, but only few could be proven to be predictive for one of the GM1 gangliosidosis subtypes or MBD. We performed genotype analyses in 16 GM1 gangliosidosis patients of all phenotypes and detected 28 different genetic lesions. Among these, p.I55FfsX16, p.W65X, p.F107L, p.H112P, p.C127Y, p.W161X, p.I181K, p.C230R, p.W273X, p.R299VfsX5, p.A301V, p.F357L, p.K359KfsX23, p.L389P, p.D448V, p.D448GfsX8, and the intronic mutation IVS6-8A>G have not been published so far. Due to their occurrence in homozygous patients, four mutations could be correlated to a distinct GM1 gangliosidosis phenotype. Furthermore, the missense mutations from heteroallelic patients and three artificial nonsense mutations were characterized by overexpression in COS-1 cells, and the subcellular localization of the mutant proteins in fibroblasts was assessed. The phenotype specificity of 10 alleles can be proposed on the basis of our results and previous data.

Abstract
INTRODUCTION Polysomnography (PSG) is one of the most important noninvasive methods for studying maturation of the child brain. Sleep in infants is significantly different from sleep in adults. This paper addresses the problem of computer analysis of neonatal polygraphic signals. METHODS We applied methods designed for differentiating three important neonatal behavioral states: quiet sleep, active sleep, and wakefulness. The proportion of these states is a significant indicator of the maturity of the newborn brain in clinical practice. In this study, we used data provided by the Institute for Care of Mother and Child, Prague (12 newborn infants of similar postconceptional age). The data were scored by an experienced physician to four states (wake, quiet sleep, active sleep, movement artifact). For accurate classification, it was necessary to determine the most informative features. We used a method based on power spectral density (PSD) applied to each EEG channel. We also used features derived from electrooculogram (EOG), electromyogram (EMG), ECG, and respiration [pneumogram (PNG)] signals. The most informative feature was the measure of regularity of respiration from the PNG signal. We designed an algorithm for interpreting these characteristics. This algorithm was based on Markov models. RESULTS The results of automatic detection of sleep states were compared to the "sleep profiles" determined visually. We evaluated both the success rate and the true positive rate of the classification, and statistically significant agreement of the two scorings was found. Two variants, for learning and for testing, were applied, namely learning from the data of all 12 newborns and tenfold cross-validation, and learning from the data of 11 newborns and testing on the data from the 12th newborn. We utilized information obtained from several biological signals (EEG, ECG, PNG, EMG, EOG) for our final classification. We reached the final success rate of 82.5%. The true positive rate was 81.8% and the false positive rate was 6.1%. DISCUSSION The most important step in the whole process is feature extraction and feature selection. In this process, we used visualization as an additional tool that helped us to decide which features to select. Proper selection of features may significantly influence the success rate of the classification. We made a visual comparison of the computed features with the manual scoring provided by the expert. A hidden Markov model was used for classification. The advantage of this model is that it determines the future behavior of the process by its present state. In this way, it preserves information about temporal development.

Abstract
We report on a male proband with pyridoxine-dependent epilepsy (PDE) and neonatal seizure onset. At the age of 31 months, a prolonged status epilepticus led to severe neurological regression with cortical blindness, loss of speech and muscular hypotonia with slow recovery over the following 3 months. At 33 months of age pyridoxine therapy was initiated with excellent response and the boy remained seizure-free on pyridoxine monotherapy, except for two occasions with seizure recurrence 10 days after accidental pyridoxine withdrawal. alpha-aminoadipic semialdehyde dehydrogenase (antiquitin) deficiency was indicated by elevated pipecolic acid concentrations in plasma and alpha-aminoadipic semialdehyde excretion in urine. Molecular analysis of the antiquitin gene revealed a novel missense mutation c.57insA, while the mutation of the other allele remained unidentified so far. Despite the delay in diagnosis and prolonged status epilepticus, neuropsychological evaluations at the ages of 11 and 18 years demonstrated full-scale IQ of 93 and 92, respectively, with better verbal IQ (103 and 101) than performance IQ (85 and 82).
