Experiences of people with multiple sclerosis and clinicians in using cognitive behavioural therapies for hidden symptoms: a systematic review and meta-aggregation. J Neurol 2024; 271:1084-1107. [PMID: 38219252 DOI: 10.1007/s00415-023-12116-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 10/31/2023] [Accepted: 11/13/2023] [Indexed: 01/16/2024]
Abstract
PURPOSE Cognitive behavioural therapies (CBTs) are a standard of care for treatment of many 'hidden symptoms' in people with MS (PwMS), such as stress, depression, and fatigue. However, these interventions can vary widely in formatting and may not be tailored for PwMS. To optimize CBTs for MS, understanding the experiences of PwMS and clinicians is essential. This systematic review and meta-aggregation synthesizes existing qualitative data on stakeholder perspectives of CBTs for PwMS. METHODS Systematic searches across five major electronic databases were conducted. Studies reporting qualitative data were identified. Two reviewers performed screening, quality assessment, data extraction, and certainty of evidence assessments. Meta-aggregation was performed as per the Joanna Briggs Institute approach, entailing qualitative data extraction, developing categories, and synthesizing overall findings. RESULTS Twenty-eight studies were included in this review, comprising data from 653 PwMS and 47 clinicians. In the meta-aggregation, 122 qualitative results were extracted and grouped into nine categories. Categories were then combined into six synthesized findings: (1) setting the context-life with MS, (2) reasons for participating in CBTs, (3) acceptability of and experiences with participating in CBTs, (4) perceived benefits of CBTs, (5) perceived challenges with CBTs, and (6) suggestions to improve CBTs for PwMS. CONCLUSIONS A range of benefits including psychological, social, and lifestyle improvements were reported, but varied based on the design of the CBT intervention. Future CBT interventions should be tailored to participant needs, delivered in group settings, offer online options, and be delivered by a trained facilitator familiar with MS. Further exploration of the ideal CBT design for PwMS, as well as engagement with caregivers and clinicians treating MS, is warranted.

Observation of an exotic insulator to insulator transition upon electron doping the Mott insulator CeMnAsO. Nat Commun 2023; 14:7037. [PMID: 37923745 PMCID: PMC10624918 DOI: 10.1038/s41467-023-42858-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Accepted: 10/17/2023] [Indexed: 11/06/2023] Open
Abstract
A promising route to discover exotic electronic states in correlated electron systems is to vary the hole or electron doping away from a Mott insulating state. Important examples include quantum criticality and high-temperature superconductivity in cuprates. Here, we report the surprising discovery of a quantum insulating state upon electron doping the Mott insulator CeMnAsO, which emerges below a distinct critical transition temperature, TII. The insulator-insulator transition is accompanied by a significant reduction in electron mobility as well as a colossal Seebeck effect and slow dynamics due to decoupling of the electrons from the lattice phonons. The origin of the transition is tentatively interpreted in terms of many-body localization, which has not been observed previously in a solid-state material.

Mental health and loneliness in Scottish schools: A multilevel analysis of data from the health behaviour in school-aged children study. BRITISH JOURNAL OF EDUCATIONAL PSYCHOLOGY 2023; 93:608-625. [PMID: 36683467 PMCID: PMC10952245 DOI: 10.1111/bjep.12581] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Accepted: 12/26/2022] [Indexed: 01/24/2023]
Abstract
BACKGROUND Adolescent loneliness and poor mental health represent dual public health concerns. Yet, associations between loneliness and mental health, and critically, how these associations vary in school settings are less understood. AIMS Framed by social-ecological theory, we aimed to identify key predictors of adolescent mental health and examine school-level variation in the relationship between loneliness and mental health. SAMPLE Cross-sectional data on adolescents from the 2018 wave of the Health Behaviour in School-aged Children study (HBSC) in Scotland were used (N = 5286). METHODS Mental health was measured as a composite variable containing items assessing nervousness, irritability, sleep difficulties and feeling low. Loneliness was measured via a single item assessing how often adolescents felt 'left out'. Multilevel models were used to identify social-ecological predictors of mental health, associations with loneliness and between-school variation. RESULTS Loneliness, as well as demographic, social and school factors, was found to be associated with mental health. Mental health varied across schools, with the between-school difference greater among adolescents with high levels of loneliness. Additionally, the negative effect of loneliness on mental health was stronger in schools with lower average mental health scores. CONCLUSIONS The findings suggest that schools can play an important role in shaping adolescent mental health. Our study uniquely identifies that school-based interventions targeting mental health may be especially necessary among lonely adolescents, and programmes aimed at tackling loneliness may be more beneficial in schools with poorer mental health.

Abstract
UNLABELLED We study the microbiome of sea water collected from two locations of the Barbadian coral reefs. The two sites differ in several environmental and ecological variables including their endogenous benthic community and their proximity to urban development and runoffs from inland watersheds. The composition of the microbial communities was estimated using whole genome DNA shotgun sequencing with adjuvant measurements of chemical and environmental qualities. Although both sites exhibit a similar degree of richness, the less urbanized site (Maycocks reef at Hangman's Bay) has a strong concentration of phototrophs whereas the more urbanized location (Bellairs reef at Folkstone) is enriched for copiotrophs, macroalgal symbionts and marine-related disease-bearing organisms from taxa scattered across the tree of life. Our results are concordant with previous profiles of warm ocean surface waters, suggesting our approach captures the state of each coral reef site, setting the stage for longitudinal studies of marine microbiome dynamics in Barbados.

Abstract
The purpose of this review is to scope the literature on the conceptualization, use, and outcomes associated with empathy and compassion in physical medicine and rehabilitation. Eligible studies included quantitative, qualitative, or mixed-methods research that presented primary data on the conceptualization, use, and outcomes associated with empathy and compassion in physical medicine and rehabilitation. Relevant studies were identified through CINAHL, Cochrane Library, EMBASE, MEDLINE, and PEDRO. Twenty-four studies were included (participant n = 3715): 13 quantitative, six mixed-methods, and five qualitative. In qualitative analysis, empathy and compassion were conceptualized as both intrinsic and exhibitory. Where self-compassion was examined as an intervention for patients, improvements in anxiety, depression, and quality of life were reported. Survey data suggested that when rehabilitation health care providers were perceived to be more empathic, patients reported greater treatment satisfaction, acceptance, adherence, and goal attainment. Individuals receiving and health care providers who deliver rehabilitative care conceptualize empathy and compassion as valuable in physical medicine and rehabilitation settings, with cognitive and behavioural elements described. Health care provider empathy and compassion-based interventions may influence outcomes positively in this context. More research is needed to understand the mechanisms of action of empathy and compassion and effectiveness in physical medicine and rehabilitation settings.

Defining research priorities for youth public mental health: reflections on a coproduction approach to transdisciplinary working. Health Res Policy Syst 2022; 20:72.

Abstract
BACKGROUND With most mental health problems established during childhood/adolescence, young people must be a key focus of public mental health approaches. Despite the range of factors known to influence mental health, evidence for effective interventions is lacking for this age group. This study aimed to define priorities for future public health intervention-focused research to support youth mental health by engaging with transdisciplinary stakeholder groups. METHODS Our coproduction approach involved priority-setting workshops with young people, researchers, practitioners and policy-makers. Each workshop focused on three thematic areas: social connections and relationships; schools and other education settings; and key groups at greater risk of mental ill-health, specifically LGBTQ+ and care-experienced young people. Workshop outputs were synthesized to define research priorities. RESULTS This paper presents the research priorities that were defined through the priority-setting workshops, and our reflections on the coproduction approach to guide future similar activities undertaken by others. Ten priorities for youth public mental health research were defined, covering the following areas: building supportive relationships; whole system approaches; social media; support at times of transition; improving links between different services; development and training for those who support young people; staff mental health; engaging with families; awareness of and access to services; and out-of-school and community settings. CONCLUSIONS These research priorities can inform future intervention development to support youth public mental health. Our transdisciplinary approach means the identified research priorities are likely to be relevant to young people's experiences and needs, and to fit with the needs of those working in practice and policy to support young people.

Abstract
In order to address the oft-cited societal, economic, and health and social care impacts of neurodegenerative diseases, such as Alzheimer's disease, we must move decisively from reactive to proactive clinical practice and to embed evidence-based brain health education throughout society. Most disease processes can be at least partially prevented, slowed, or reversed. We have long neglected to intervene in neurodegenerative disease processes, largely due to a misconception that their predominant symptom - cognitive decline - is a normal, age-related process, but also due to a lack of multi-disciplinary collaboration. We now understand that there are modifiable risk factors for neurodegenerative diseases, that successful management of common comorbidities (such as diabetes and hypertension) can reduce the incidence of neurodegenerative disease, and that disease processes begin (and, crucially, can be detected, reduced, and delayed, prevented, or treated) decades earlier in life than had previously been appreciated. Brain Health Scotland, established by Scottish Government and working in partnership with Alzheimer Scotland, propose far-reaching public health and clinical practice approaches to reduce neurodegenerative disease incidence. Focusing here on Brain Health Scotland's clinical offerings, we present the Scottish Model for Brain Health Services. To our knowledge, the Scottish Model for Brain Health, built on foundations of personalised risk profiling, targeted risk reduction and prevention, early disease detection, equity of access, and harnessing comprehensive data to assist in clinical decision-making, marks the first example of a nationwide approach to overhauling clinical, societal, and political approaches to the prevention, assessment, and treatment of neurodegenerative disease.

Abstract
Abstract
Few interventions are truly simple; complexity can arise from various sources, e.g.:
Aspects of the intervention itself, such as the number of intervention components, the number of groups targeted, how dynamic the intervention is permitted to be. The context in which the intervention is developed and delivered, such as the social, political, economic, and geographical context.
Complex intervention research should be approached with an awareness of these sources of complexity. Systems thinking can be helpful to understanding the dynamic interaction between interventions and their context. This presentation will introduce concepts of complex adaptive systems, e.g. feedback loops, adaptation, emergence, that should be considered when developing and evaluating complex interventions. It will then introduce participants to the research perspectives set out in the new framework: efficacy, effectiveness, theory-based, and systems perspectives. Each perspective is associated with a different type of research question, and therefore appropriate in different circumstances. The presentation will provide information to support participants to consider the research perspective(s) most suited to the research challenge that they are aiming to address.
Main messages
There are multiple sources of complexity, each of which can affect how the intervention works or contributes to change. Complex intervention research can take an efficacy, effectiveness, theory-based, or systems perspective, the choice of which is based on what is known already and what further evidence would be most useful.

Abstract
Abstract
The new framework will be presented. The main phases of intervention research: development or identification, feasibility, evaluation and implementation are connected to 6 core elements:
Context: any feature of the circumstances in which an intervention is conceived, developed, evaluated and implemented Programme theory: how an intervention is expected to lead to its effects and under what conditions. Programme theory should be tested and refined at all stages and used to guide the identification of uncertainties and research questions Stakeholders: those who are targeted by the intervention, involved in its development or delivery, or more broadly those whose personal or professional interests are affected, that is who have a stake in the topic. This includes patients, the public, and professionals Refinement: the process of ‘fine tuning' or making changes to the intervention once a preliminary version has been developed Uncertainties: identifying key uncertainties that exist given what is already known and what the programme theory, researchers and stakeholders identify as being most important to find out. These judgements inform the framing of research questions that, in turn, govern research perspective choice Economic considerations: exploring the comparative resource and outcome consequences of the interventions for those people and organisations affected
The presentation will discuss how to use the framework, highlighting that complex intervention research can be an iterative process. Repeating of phases is preferable to automatic progression to the next phase if uncertainties remain unresolved.
Main messages
Complex intervention research may begin at any phase, depending on what is appropriate for the intervention in question, and does not necessarily move sequentially through the phases. The core elements should be considered early and revisited continually throughout, as this will make it most likely that the intervention will be implementable in practice.

Abstract
PURPOSE Mindfulness-based interventions (MBIs) are effective treatments for stress, anxiety, and depression in PwMS. However, low adherence and high attrition may limit effectiveness. Qualitative research can provide important insights into MBI acceptability, accessibility, and implementation. This systematic review and meta-aggregation evaluated qualitative research findings on the use of MBIs for PwMS. METHODS Systematic searches were undertaken in six major electronic databases. Studies using qualitative or mixed methods were included. Two reviewers screened, data extracted, and critically appraised studies. Meta-aggregation was performed following the Joanna Briggs Institute approach, extracting findings, developing categories, and synthesizing findings. RESULTS Six eligible papers, including 136 PwMS were included in meta-aggregation. 136 findings were extracted, grouped into 17 categories, with four synthesized findings: (1) "accessing mindfulness," (2) "a sense of belonging," (3) "experiencing mindfulness," and (4) "making mindfulness more relevant and sustainable for PwMS." CONCLUSIONS MBIs for PwMS need to take into consideration disability which can limit accessibility. Online MBIs (synchronous and asynchronous) appear acceptable alternatives to traditional face-to-face courses. However, PwMS benefit from shared (mindful) experiencing and highlight MBI instructors as crucial in helping them understand and practice mindfulness. Involving PwMS in design, delivery, and iterative refinement would make MBIs more relevant to those taking part.IMPLICATIONS FOR REHABILITATIONBoth face-to-face and online Mindfulness-based interventions (MBIs) appear acceptable to PwMS and, ideally, people should be offered a choice in training modality.PwMS derive benefit from undertaking MBIs with their peers, where a sense of camaraderie and belonging develop through shared (mindful) experiences.Instructors delivering MBIs for PwMS should be knowledgeable about the condition; participants describe how the instructor has a key role in helping them practice mindfulness effectively in the context of unpleasant experiences associated with MS.MBIs tailored for PwMS should include a pre-course orientation session, clearly articulate how mindfulness practices can help with MS, provide well-organized course materials in large font size, and deliver individual mindfulness practices flexibly depending on participant need.

Abstract
Mutagenic compounds are a potent source of human disease. By inducing genetic instability, they can accelerate the evolution of human cancers or lead to the development of genetically inherited diseases. Here, we show that in addition to genetic mutations, mutagens are also a powerful source of transcription errors. These errors arise in dividing and nondividing cells alike, affect every class of transcripts inside cells, and, in certain cases, greatly exceed the number of mutations that arise in the genome. In addition, we reveal the kinetics of transcription errors in response to mutagen exposure and find that DNA repair is required to mitigate transcriptional mutagenesis after exposure. Together, these observations have far-reaching consequences for our understanding of mutagenesis in human aging and disease, and suggest that the impact of DNA damage on human physiology has been greatly underestimated.

Abstract
Objectives To study barriers and facilitators to implementation of mindfulness-based stress reduction for people with multiple sclerosis. Methods Qualitative interviews were used to explore barriers and facilitators to implementation of mindfulness-based stress reduction, including 33 people with multiple sclerosis, 6 multiple sclerosis clinicians and 2 course instructors. Normalisation process theory provided the underpinning conceptual framework. Data were analysed deductively using normalisation process theory constructs (coherence, cognitive participation, collective action and reflexive monitoring). Results Key barriers included mismatched stakeholder expectations, lack of knowledge about mindfulness-based stress reduction, high levels of comorbidity and disability and skepticism about embedding mindfulness-based stress reduction in routine multiple sclerosis care. Facilitators to implementation included introducing a pre-course orientation session; adaptations to mindfulness-based stress reduction to accommodate comorbidity and disability and participants suggested smaller, shorter classes, shortened practices, exclusion of mindful-walking and more time with peers. Post-mindfulness-based stress reduction booster sessions may be required, and objective and subjective reports of benefit would increase clinician confidence in mindfulness-based stress reduction. Discussion Multiple sclerosis patients and clinicians know little about mindfulness-based stress reduction. Mismatched expectations are a barrier to participation, as is rigid application of mindfulness-based stress reduction in the context of disability. Course adaptations in response to patient needs would facilitate uptake and utilisation. Rendering access to mindfulness-based stress reduction rapid and flexible could facilitate implementation. Embedded outcome assessment is desirable.

Abstract
BACKGROUND Mastery is the sense of being in control of one's life and improvement in mastery may help to enhance quality of life. Little research has explored mastery in people with multiple sclerosis (MS), including its association with quality of life. OBJECTIVE To explore the association between mastery and health-related quality of life (HRQOL) in people with MS. METHOD Two cross-sectional cohorts of adults with MS (n = 1401 and n = 573), recruited through convenience sampling, completed an online survey which measured mastery using the Pearlin Mastery Scale, physical and mental HRQOL via physical and mental health composite scores of MSQOL-54, along with other covariates, including demographics, clinical characteristics and lifestyle factors. Linear regression assessed associations between mastery and physical HRQOL adjusting for age, sex, education, disability and depression, and between mastery and mental HRQOL adjusting for age, sex, education, disability and clinically significant fatigue. RESULTS Greater mastery score was associated with higher physical and mental HRQOL in both cohorts, such that a one-point increase in the PMS was associated with an increase of 2.9 (95% Confidence Interval (CI): 2.6, 3.1) and 2.8 points (95% CI: 2.4, 3.2) in the means of physical HRQOL score in the first and second cohorts respectively, and a 2.9-point (95% CI: 2.7, 3.1) and 3.1-point (95% CI: 2.7, 3.4) increase in the means of mental HRQOL score. A dose-dependent relationship was demonstrated between a quartile categorical mastery variable and both physical and mental HRQOL in both cohorts. Mastery was associated with all subscores of both physical and mental HRQOL. CONCLUSIONS Greater mastery is associated with better physical and mental quality of life. Efforts to improve the sense of self control and agency of people with MS may have benefits for their quality of life, even despite clinical features of the illness.

Abstract
OBJECTIVE Impairment of mental well-being (anxiety, depression, stress) is common among people with multiple sclerosis (PwMS). Treatment options are limited, particularly for anxiety. The aim of this study was to update our previous systematic review (2014) and evaluate via meta-analysis the efficacy of mindfulness-based interventions (MBIs) for improving mental well-being in PwMS. METHODS Systematic searches for eligible randomised controlled trials (RCTs) were carried out in seven major databases (November 2017, July 2018), using medical subject headings and key words. Studies were screened, data extracted, quality appraised and analysed by two independent reviewers, using predefined criteria. Study quality was assessed using the Cochrane Collaboration risk of bias tool. Mental well-being was the primary outcome. Random effects model meta-analysis was performed, with effect size reported as standardised mean difference (SMD). RESULTS Twelve RCTs including 744 PwMS were eligible for inclusion in the systematic review, eight had data extractable for meta-analysis; n=635. Ethnicity, socioeconomic status, comorbidity and disability were inconsistently reported. MBIs varied from manualised to tailored versions, lasting 6-9 weeks, delivered individually and via groups, both in person and online. Overall SMD for mental well-being (eight studies) was 0.40 (0.28-0.53), p<0.01, I2=28%; against active comparators only (three studies) SMD was 0.17 (0.01-0.32), p<0.05, I2 =0%. Only three adverse events were reported. CONCLUSIONS MBIs are effective at improving mental well-being in PwMS. More research is needed regarding optimal delivery method, cost-effectiveness and comparative-effectiveness. PROSPERO REGISTRATION NUMBER CRD42018093171.

Abstract
We report three paediatric cases of severe dehydration and hyponatraemia with circulatory compromise associated with the use of external ventricular drainage of cerebrospinal fluid. Two of the children had cardiac arrests. All were successfully resuscitated. While there were additional factors that contributed to other fluid losses, and fluid balance data are incomplete, these cases highlight a need for increased vigilance when managing children with external ventricular drains.

Abstract
Background Young people in the UK are at highest risk of sexually transmitted infections and report higher levels of unsafe sex than any other age group. Involving peer supporters in intervention delivery is acceptable to students and effective in reducing risk behaviours via ‘diffusion of innovation’, particularly where peer supporters are influential in their networks. Informal peer-led interventions offer a useful alternative to peer-led didactic teaching, which has shown limited effects. Building on the successful ASSIST anti-smoking intervention, the ‘STis And Sexual Health’ (STASH) intervention involves identification and recruitment of the most influential students as peer supporters, training and support to these students by specialist trainers, positive sex and relationships messages, spread by peer supporters to their friendship groups in person and via social media. Methods/design This protocol describes a feasibility trial of the STASH intervention in six schools. It builds on an earlier study phase of intervention co-development using patient and public involvement (PPI) activities, followed by a pilot of intervention components and evaluation tools in one school. Participants are fourth year (S4) students (aged 14–16) in state-funded Scottish secondary schools who have received some level of teacher-led sex education. The previous cohort of S4 students (those completing S4 in the year prior to the intervention) will serve as controls. Data will be collected from controls (month 16), baseline (month 20–21) and follow-up (month 27–30) via a web-based questionnaire, which will measure (and test the reliability of) primary outcome measures for a phase III trial (delayed initiation of/abstinence from sex and consistent condom use), secondary outcomes and mediators of sexual behaviour (including school climate and social networks). The main feasibility outcome is whether the study meets pre-set progression criteria regarding feasibility and acceptability, measured largely via a process evaluation (basic measures in all 6 schools and in-depth in 2-4 schools). An economic evaluation reporting costs alongside consequences will be conducted. Discussion This study will inform decisions on the feasibility, design and sample size for a phase III effectiveness trial to assess whether the STASH intervention is effective in reducing the risk of sexually transmitted infections in young people.

Patient-reported outcomes are worse for progressive-onset multiple sclerosis than relapse-onset multiple sclerosis, particularly early in the disease process. Eur J Neurol 2018; 26:155-161. [PMID: 30133059 DOI: 10.1111/ene.13786] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2018] [Accepted: 08/17/2018] [Indexed: 02/03/2023]
Abstract
BACKGROUND AND PURPOSE Treatments for progressive-onset multiple sclerosis (MS) are lacking. To improve the disease management for progressive-onset MS, the differences between relapse-onset MS and progressive-onset MS in patient-reported disability, progression and symptoms were examined. METHODS A total of 1985 participants of the Australian Multiple Sclerosis Longitudinal Study were included. Associations between onset type and outcomes were assessed with negative binomial regression. RESULTS The severity of 17 of the 19 outcomes was significantly higher for progressive-onset MS patients than relapse-onset MS patients, including perspectives from disability, progression over the last year, fatigue, sensory, walking difficulties, pain, balance, spasticity, sexual dysfunction, bladder, bowel, anxiety, depression and the European quality of life (EQ-5D) (P < 0.05; adjusted mean ratio ranged from 1.11 to 1.52). The differences between the two onset types were most pronounced early in the disease process and reduced with increasing MS duration, and the interaction was significant for disability, progression over the last year, walking difficulties, bladder problems, bowel problems and spasticity. CONCLUSION Participants with progressive-onset MS were significantly worse off on nearly all patient-reported outcomes than relapse-onset MS participants, and the differences were most pronounced early in the disease course, highlighting the importance of early intervention for those with progressive-onset MS.

Self-reported cognitive function in a large international cohort of people with multiple sclerosis: associations with lifestyle and other factors. Eur J Neurol 2018; 26:142-154. [PMID: 30133057 PMCID: PMC6585853 DOI: 10.1111/ene.13784] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2018] [Accepted: 08/16/2018] [Indexed: 01/19/2023]
Abstract
Background and purpose We aimed to estimate the prevalence of perceived cognitive impairment (PCI) and explore its associations with lifestyle and disease characteristics in a large international cohort of people with multiple sclerosis (MS). Methods This study was a cross‐sectional analysis. Participants rated their cognitive function over the preceding 4 weeks using four questions in a subscale within the Multiple Sclerosis Quality of Life questionnaire (MSQOL‐54). These questions assessed perceived concentration, attention and memory by the patient and family/friends. Four definitions of PCI were derived, ranging from lowest to highest specificity. Associations with PCI were assessed by log‐binomial regression. Results The prevalence of PCI in our sample ranged from 41.0% (95% confidence interval, 39.0–43.0) using the least‐specific definition to 11.6% (95% confidence interval, 10.3–12.9) using the most specific definition. A number of factors were associated with PCI, increasing in magnitude as the definition specificity increased, including positive associations for smoking and body mass index, whereas physical activity, dietary quality and use of vitamin D/omega‐3 supplements were inversely associated with PCI. Conclusions Our study reports associations between healthy lifestyle behaviours and PCI in people with MS. Although reverse causality is a potential explanation for our findings, previous studies have shown comparable associations with healthy lifestyle and MS onset and progression. Subject to external validation, these results suggest benefits realized from a healthy lifestyle in people with MS.

Psychoeducational interventions in adolescent depression: A systematic review. PATIENT EDUCATION AND COUNSELING 2018; 101:804-816. [PMID: 29103882 PMCID: PMC5933524 DOI: 10.1016/j.pec.2017.10.015] [Citation(s) in RCA: 44] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/12/2017] [Revised: 10/12/2017] [Accepted: 10/21/2017] [Indexed: 05/13/2023]
Abstract
BACKGROUND Adolescent depression is common and leads to distress and impairment for individuals/families. Treatment/prevention guidelines stress the need for good information and evidence-based psychosocial interventions. There has been growing interest in psychoeducational interventions (PIs), which broadly deliver accurate information about health issues and self-management. OBJECTIVE, METHODS Systematic search of targeted PIs as part of prevention/management approaches for adolescent depression. Searches were undertaken independently in PubMed, PsycINFO, EMBASE, guidelines, reviews (including Cochrane), and reference lists. Key authors were contacted. No restrictions regarding publishing dates. RESULTS Fifteen studies were included: seven targeted adolescents with depression/depressive symptoms, eight targeted adolescents 'at risk' e.g. with a family history of depression. Most involved family/group programmes; others included individual, school-based and online approaches. PIs may affect understanding of depression, identification of symptoms, communication, engagement, and mental health outcomes. CONCLUSION, PRACTICE IMPLICATIONS PIs can have a role in preventing/managing adolescent depression, as a first-line or adjunctive approach. The limited number of studies, heterogeneity in formats and evaluation, and inconsistent approach to defining PI, make it difficult to compare programmes and measure overall effectiveness. Further work needs to establish an agreed definition of PI, develop/evaluate PIs in line with frameworks for complex interventions, and analyse their active components.

Acceptability of mindfulness from the perspective of stroke survivors and caregivers: a qualitative study. Pilot Feasibility Stud 2018; 4:57. [PMID: 29497560 PMCID: PMC5827989 DOI: 10.1186/s40814-018-0244-1] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2017] [Accepted: 02/02/2018] [Indexed: 01/10/2023] Open
Abstract
Background Depression is very common among stroke survivors with estimated prevalence rates of approximately 33% among stroke survivors, but treatment options are limited. Mindfulness-Based Stress Reduction (MBSR) is an effective treatment for depression generally, but benefits in stroke patients are unclear. The aim of this study was to determine the feasibility of delivering MBSR to stroke survivors and their caregivers in the community. We conducted a study to gain views of MBSR as a potential treatment option among stroke survivors and their caregivers in the community. Methods Participants were recruited from an urban community in Scotland (UK) using newspaper adverts, social media and support groups run by health charities. A 2-h MBSR taster session was delivered by two experienced mindfulness instructors, followed by focus group sessions with all participants on their user experience and suggestions for MBSR modifications for stroke survivors. The focus group sessions were audio recorded and transcribed verbatim. Transcript data were analysed thematically using the framework approach. Results The study sample consisted of 28 participants (16 females); there were 21 stroke survivors (11 females) and 7 caregivers (5 females). The median age for participants was 60 years.Most participants described the MBSR taster session as a positive experience. The main challenge reported was trying to maintain focus and concentration throughout the MBSR session. Some participants expressed reservations about the duration of standard mindfulness course sessions, suggesting a preference for shorter sessions. The potential for achieving better control over negative thoughts and emotions was viewed as a potential facilitator for future MBSR participation. Participants suggested having an orientation session prior to starting an 8-week course as a means of developing familiarity with the MBSR instructor and other participants. Conclusion It was feasible to recruit 21 stroke survivors and 7 caregivers for MBSR taster sessions in the community. A shorter MBSR session and an orientation session prior to the full course are suggestions for potential MBSR modifications for stroke survivors, which needs further research and evaluation.

Abstract
Youth offending is a problem worldwide. Young people in the criminal justice system have frequently experienced adverse childhood circumstances, mental health problems, difficulties regulating emotions and poor quality of life. Mindfulness-based interventions can help people manage problems resulting from these experiences, but their usefulness for youth offending populations is not clear. This review evaluated existing evidence for mindfulness-based interventions among such populations. To be included, each study used an intervention with at least one of the three core components of mindfulness-based stress reduction (breath awareness, body awareness, mindful movement) that was delivered to young people in prison or community rehabilitation programs. No restrictions were placed on methods used. Thirteen studies were included: three randomized controlled trials, one controlled trial, three pre-post study designs, three mixed-methods approaches and three qualitative studies. Pooled numbers (n = 842) comprised 99% males aged between 14 and 23. Interventions varied so it was not possible to identify an optimal approach in terms of content, dose or intensity. Studies found some improvement in various measures of mental health, self-regulation, problematic behaviour, substance use, quality of life and criminal propensity. In those studies measuring mindfulness, changes did not reach statistical significance. Qualitative studies reported participants feeling less stressed, better able to concentrate, manage emotions and behaviour, improved social skills and that the interventions were acceptable. Generally low study quality limits the generalizability of these findings. Greater clarity on intervention components and robust mixed-methods evaluation would improve clarity of reporting and better guide future youth offending prevention programs.

Should old age psychiatry develop memory clinics? A comparison with domiciliary work. PSYCHIATRIC BULLETIN 2018.

Abstract
Aims and MethodMemory clinics have become very popular in old age psychiatry and there is some pressure for them to be developed in old age services. However, there is little evidence to suggest that they are more advantageous over the traditional domiciliary visits or who should be seen in clinic. This was a naturalistic comparison of 76 consecutive new referrals to a memory clinic, with 74 consecutive new domiciliary requests within the same service over the same period of time. A retrospective case note review collected the clinical features and an 18-month prospective follow-up examined the subsequent clinical management.Clinical ImplicationsThe two groups were characterised more by their similarities than their differences. However, the domiciliary group had greater behavioural and psychological complications. The memory clinic patients were less likely to receive psychotropic medication and here more likely to be followed up.ResultsWe conclude that memory clinics might be less suitable for patients with prominent psychiatric complications. Memory clinics could complement the domiciliary model by providing early psychosocial/neuropsychiatric approaches, although this is likely to lead to an increased clinical case-load.

Abstract
SummaryBipolar disorder is a complex disorder of mood and behaviour that requires a multimodal treatment approach. In the past 10 years there has been growing interest in psychoeducational interventions delivered as adjuncts to conventional management. Several studies have tested the effectiveness of psychoeducational treatments delivered in a variety of formats. In this article we assess the evidence for the efficacy of these interventions and consider the likely future role of structured psychoeducational treatments in clinical practice.

Protocol for a feasibility randomised controlled trial of the use of Physical ACtivity monitors in an Exercise Referral Setting: the PACERS study. Pilot Feasibility Stud 2017; 3:51. [PMID: 29238607 PMCID: PMC5725949 DOI: 10.1186/s40814-017-0194-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2017] [Accepted: 10/24/2017] [Indexed: 12/04/2022] Open
Abstract
Background Exercise referral schemes are recommended by the National Institute for Clinical Excellence (NICE) for physical activity promotion among inactive patients with health conditions or risk factors. Whilst there is evidence for the initial effectiveness and cost-effectiveness of such schemes for increasing physical activity, evidence of long-term effects is limited. Techniques such as goal setting, self-monitoring and personalised feedback may support motivation for physical activity. Technologies such as activity monitoring devices provide an opportunity to enhance delivery of motivational techniques. This paper describes the PACERS study protocol, which aims to assess the feasibility and acceptability of implementing an activity monitor within the existing Welsh National Exercise Referral Scheme (NERS) and proposed evaluation methodology for a full-scale randomised controlled trial. Methods/design The PACERS study consists of a pilot randomised controlled trial, process evaluation and exploratory economic analyses. Participants will be recruited from the generic pathway of the Welsh NERS and will be randomly assigned to receive the intervention or usual practice. Usual practice is a 16-week structured exercise programme; the intervention consists of an accelerometry-based activity monitor (MyWellnessKey) and an associated web platform (MyWellnessCloud). The primary outcomes are predefined progression criteria assessing the acceptability and feasibility of the intervention and feasibility of the proposed evaluation methodology. Postal questionnaires will be completed at baseline (time 0: T0), 16 weeks after T0 (T1) and 12 months after T0 (T2). Routinely collected data will also be accessed at the same time points. A sub-sample of intervention participants and exercise referral staff will be interviewed following initiation of intervention delivery and at the end of the study. Discussion The PACERS study seeks to assess the feasibility of adding a novel motivational component to an existing effective intervention in order to enhance effects on physical activity and support longer-term maintenance. The study will provide insight into the acceptability of activity-monitoring technologies to an exercise referral population and delivery staff. Data from this study will be used to determine whether and how to proceed to a full-scale trial of effectiveness of the intervention, including any necessary refinements to intervention implementation or the proposed evaluation methodology.

Abstract
OBJECTIVE Understanding mechanisms of motivational interviewing (MI) could improve practice. Planning is important for behavior change, and a component of MI. We aimed to develop a scale to measure planning talk within MI and explore the potential association between planning and weight loss maintenance (WLM). METHODS A literature review and thematic analysis was used to develop the coding system. Reliability was tested using MI examples and a transcript. It was applied to 50 sessions and associations between planning and WLM were analyzed using logistic and linear regression. RESULTS The coding system included: past, continuing, future and hypothetical plans and goal setting, varying on specificity and commitment. The percentage agreement was 86% and 75% for examples and transcript reliability respectively. Frequent planners, potentially decrease their weight 2.8kg(-9.7, 0.6) and BMI 1.2kg/m2(-3.1, 0.4) more compared to less frequent planners. Frequent goal setters increase their BMI(3.6kg/m2, 1.5, 5.7) and weight (9.5kg, 3.4, 15.6) compared to non-goal setters. CONCLUSION It is feasible to measure planning, with acceptable agreement. Limited conclusions for the potential associations were demonstrated. PRACTICE IMPLICATIONS This is the first scale to measure planning, an important aspect of MI which has received less attention.

Abstract
BACKGROUND Anxiety and depression are common in multiple sclerosis (MS). We evaluated the prevalence and factors associated with anxiety, depression and fatigue at the 5-year review of a longitudinal cohort study following a first clinical diagnosis of CNS demyelination (FCD). METHODS Cases with a FCD were recruited soon after diagnosis and followed annually thereafter. A variety of environmental, behavioural and clinical covariates were measured at five-year review. Anxiety and depression were measured using the Hospital Anxiety & Depression Scale (HADS), and fatigue by the Fatigue Severity Scale (FSS). RESULTS Of the 236 cases, 40.2% had clinical anxiety (median HADS-A: 6.0), 16.0% had clinical depression (median HADS-D: 3.0), and 41.3% had clinical fatigue (median FSS: 4.56). The co-occurrence of all three symptoms was 3.76 times greater than expectation. Younger age, higher disability, concussion or other disease diagnosis were independently associated with a higher anxiety score; male sex, higher disability, being unemployed, less physical activity, and antidepressant and/or anxiolytic-sedative medication use were independently associated with a higher depression score. Higher disability, immunomodulatory medication use, other disease diagnosis and anxiolytic-sedative medication use were independently associated with having fatigue, while female sex, higher BMI, having had a concussion, being unemployed and higher disability were associated with a higher fatigue score. CONCLUSION These results support previous findings of the commonality of anxiety, depression and fatigue in established MS and extend this to post-FCD and early MS cases. The clustering of the three symptoms indicates that they may share common antecedents.

Abstract
BACKGROUND Hyperglycaemia has been associated with adverse outcomes in several different hospital populations. AIM The aim of this study was to investigate the relationship between admission blood glucose level (BGL) and outcomes in all patients admitted through the emergency department. METHODS This study was a retrospective observational cohort study from an Australian tertiary referral hospital. Patients admitted in the first week of each month from April to October 2012 had demographic data, co-morbidities, BGL, intensive care unit admission, length of stay and dates of death recorded. Factors associated with outcomes were assessed by multi-level mixed-effects linear regression. RESULTS Admission BGL was recorded for 601 admissions with no diagnosis of diabetes and for 219 admissions diagnosed with type 2 diabetes (T2DM). In patients with no diagnosis of diabetes, admission BGL was associated with in-hospital and 90-day mortality (P < 0.001). After multivariate analysis, BGL greater than 11.5 mmol/L was significantly associated with increased mortality at 90 days (P < 0.05). In patients with T2DM increased BGL on admission was not associated with in-hospital or 90-day mortality but was associated with length of hospital stay (β: 0.22 days/mmol/L; 95% confidence interval 0.09-0.35; P < 0.001), although this association was lost on multivariable analysis. In patients with T2DM, increased coefficient of variation of BGL was also positively associated with length of hospital stay in an almost dose-dependent fashion (P < 0.001). CONCLUSION Admission BGL was independently associated with increased mortality in patients with no diagnosis of diabetes. Glycaemic variability was associated with increased length of hospital stay in patients with T2DM.

Abstract
BACKGROUND AND AIMS The treatment of peritoneal malignancies with cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) has been shown to be associated with massive surgical blood loss. Maintaining high fibrinogen levels throughout surgery may reduce blood loss in these patients. The primary aim of the study was to see if Tranexamic Acid (TXA) and cryoprecipitate reduced surgical blood loss and hence red cell transfusions. A comparison was made with a cohort of patients treated with fresh frozen plasma (FFP) alone. The secondary aim was to measure the effect of both protocols on coagulation parameters and the incidence of arterial or venous thrombosis. METHOD We used prospectively collected data from 201 patients who had complete CRS with HIPEC for peritoneal malignancy using different protocols during two discrete 12-month time periods. RESULTS The new transfusion protocol led to a higher average fibrinogen level intra-operatively and post-operatively, with a significant reduction in average RBC, FFP and platelet transfusion intra-operatively per patient from 4·2 to 1·8 units, 6·2 to 0·2 units and 0·1 to 0 units, respectively. No significant difference in PT or APTT was seen between patients treated with the standard and new protocols. Venous thrombosis occurred in seven patients treated with the standard protocol and five with the new protocol. A single case of arterial thrombosis was seen in both groups. CONCLUSION Patients treated with upfront TXA and cryoprecipitate during CRS required less RBC transfusion than those treated with the standard protocol of early FFP.

Abstract
Murine models for the study of adult stem cell populations have broadened the understanding of previously uncharacterized stem cell niches. The development of murine reporter lines for the leucine-rich repeat-containing G-protein-coupled receptor-5 (Lgr5) has highlighted the importance of this gene as a stem cell marker in the stomach, intestine, hair follicle, liver, and kidney in mice. These models however have significant limitations in terms of translational applications because of anatomical and physiological differences between humans and mice. In order to overcome these limitations, we have sought to develop a porcine LGR5 reporter line. We report the generation of a porcine stem cell reporter line using the combination of transcription activator-like effector nucleases and somatic cell NT. Transcription activator-like effector nuclease-mediated homologous recombination was used to drive the integration of an internal ribosome entry site green fluorescent protein fusion into the 3′ untranslated region of the LGR5 locus in porcine fetal fibroblast cells. Multiple cell lines were developed and screened for the proper integration event. Upon confirmation of proper integration by genomic DNA sequencing, these lines were used as donors for somatic cell NT. Transfer of the somatic cell NT reconstructed embryos to a surrogate gilt resulted in 3 live births, and the establishment of a founder line of LGR5-green fluorescent protein reporter pigs. We have begun to characterise these lines, having observed fluorescent labelling of putative stem cell populations in the intestinal crypts and hair follicles from these animals. Many of these observations parallel the expression patterns observed in similar murine models. We have confirmed the fluorescent reporter signal by immunohistochemistry using an anti-green fluorescent protein antibody, and are working towards colocalization studies using anti-LGR5 antibodies and RNA in situ hybridization, as well as the characterisation of additional stem cell populations in the pig. The development of this line of transgenic pigs represents significant progress toward the study of adult stem cells, their progenitors, and the stem cell niche, using a large animal model with an anatomy, physiology, and ability to recapitulate human disease that overcomes the current limitations of rodent models.

1 GENERATION OF A STABLE TRANSGENIC SWINE MODEL FOR CELL TRACKING AND CHROMOSOME DYNAMIC STUDIES. Reprod Fertil Dev 2016.

Abstract
Transgenic pigs are an attractive research model in the field of translational research, regenerative medicine, and stem cell therapy due to their anatomic, genetic, and physiological similarities with humans. The development of a transgenic murine model with a fusion of green fluorescent protein (GFP) to histone 2B protein (H2B, protein of nucleosome core) resulted in an easier and more convenient method for tracking cell migration and engraftment levels after transplantation as well as a way to better understand the complexity of molecular regulation within cell cycle/division, cancer biology, and chromosome dynamics. Up to now the development of a stable transgenic large animal model expressing H2B-GFP has not been described. Our objective was to develop the first transgenic porcine H2B-GFP model via CRISPR-CAS9 mediated recombination and somatic cell nuclear transfer (SCNT). Porcine fetal fibroblasts were cotransfected with CRISPR-CAS9 designed to target the 3′ untranslated region of ACTB locus and a targeting vector containing 1Kb homology arms to ACTB flanking an IRES-H2B-GFP transgene. Four days after transfection GFP cells were fluorescence activated cell sorted. Single cell colonies were generated and analysed by PCR, and heterozygous colonies were used as donor cells for SCNT. The custom designed CRISPR-CAS9 knockin system demonstrated a 2.4% knockin efficiency. From positive cells, 119 SCNT embryos were generated and transferred to a recipient gilt resulting in three positive founder boars (P1 generation). Boars show normal fertility (pregnancies obtained via AI of wild type sows). Generated P1 clones were viable and fertile with a transgene transmission rate of 55.8% (in concordance with Mendel’s law upon chi-square test with P = 0.05). Intranuclear H2B-GFP expression was confirmed via fluorescence microscopy on 8-day in vitro cultured SCNT blastocysts and a variety of tissues (heart, kidney, brain, bladder, skeletal muscle, stomach, skin, and so on) and primary cultured cells (chondrocytes, bone marrow derived, adipocyte derived, neural stem cells, and so on) from P1 cloned boars and F1 42-day fetuses and viable piglets. In addition, chromosome segregation could be easily identified during cell cycle division in in vitro cultured stem cells. Custom designed CRISPR-CAS 9 are able to drive homologous recombination in the ACTB locus in porcine fetal fibroblasts, allowing the generation of the first described viable H2B-GFP porcine model via SCNT. Generated clones and F1 generation expressed H2B-GFP ubiquitously, and transgene transmission rates were with concordance of Mendel’s law. This novel large animal model represents an improved platform for regenerative medicine and chromosome dynamic and cancer biology studies.

Abstract
BACKGROUND We sought to determine the prevalence of MS on the Isle of Man in 2006 and 2011, and the incidence and mortality rates over this interval. METHODS Cases were identified by hospital medical record review, General Practitioners and the local MS Society. The significance of the change in prevalence over time and the significance of differences in frequencies by sex and place of birth were assessed by Poisson regression. RESULTS The 2006 prevalence was 153.64 per 100,000 persons and the 2011 prevalence was 179.89. The prevalence was higher among females and persons born in the Isle of Man at both time points. The 2006-2011 incidence rate was 6.86 per 100,000 person-years, much higher among females and persons born in the Isle of Man. The prevalence sex ratios in 2006 and 2011, 2.77 and 2.59, respectively, and the incidence sex ratio, 2.19, are similar to others found in the region. The mortality rate over the study period was 2.84 per 100,000 person-years, this solely among persons born overseas. CONCLUSIONS This is the first study of MS epidemiology in the Isle of Man, finding this area to be of high prevalence and to have one of the highest incidence rates in the UK region.

Patients' perspectives of the feasibility, acceptability and impact of a group-based psychoeducation programme for bipolar disorder: a qualitative analysis. BMC Psychiatry 2015; 15:184. [PMID: 26231750 PMCID: PMC4522139 DOI: 10.1186/s12888-015-0556-0] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2014] [Accepted: 07/14/2015] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Although there is some quantitative evidence to suggest the benefits of group psychoeducation for people with bipolar disorder, patients' perspectives and experiences of group psychoeducation require in-depth exploration to enable us to better understand the feasibility, acceptability and impact of these interventions, the potential facilitators and barriers to engagement, and how to improve these interventions in the future. METHODS In-depth, semi-structured interviews were conducted with 13 participants of a psychoeducation programme for bipolar disorder in Wales, following their involvement in the programme. The data were recorded and transcribed verbatim and analysed using thematic analysis. RESULTS Findings demonstrate that group psychoeducation may impact on participants' perceived social support, knowledge and acceptance of bipolar disorder, personal insights, attitude towards medication and access to services. Key recommendations for improvement included: allowing more time for group discussions, offering group sessions to family members and avoiding use of hospital or university venues for the groups. CONCLUSIONS This is the first qualitative study of patients' perspectives of a UK-based group psychoeducation programme for people with bipolar disorder, and findings present an in-depth account of how group psychoeducation may be experienced by patients. The recommendations for improving the content and delivery of group psychoeducation for bipolar disorder may enhance engagement and widen access to such programmes. Future research into psychoeducation for bipolar disorder should explore how to target and engage people of diverse ethnic backgrounds and those in lower socioeconomic groups who are less likely to access healthcare services.

How Patients Contribute to an Online Psychoeducation Forum for Bipolar Disorder: A Virtual Participant Observation Study. JMIR Ment Health 2015; 2:e21. [PMID: 26543925 PMCID: PMC4607375 DOI: 10.2196/mental.4123] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2014] [Revised: 03/25/2015] [Accepted: 04/23/2015] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND In a recent exploratory randomized controlled trial, an online psychoeducation intervention for bipolar disorder has been found to be feasible and acceptable to patients and may positively impact on their self-management behaviors and quality of life. OBJECTIVE The objective of the study was to investigate how these patients contribute to an online forum for bipolar disorder and the issues relevant for them. METHODS Participants in the intervention arm of the Bipolar Interactive PsychoEDucation ("BIPED") trial were invited to contribute to the Beating Bipolar forum alongside receiving interactive online psychoeducation modules. Within this virtual participant observation study, forum posts were analyzed using thematic analysis, incorporating aspects of discourse analysis. RESULTS The key themes which arose from the forum posts included: medication, employment, stigma, social support, coping strategies, insight and acceptance, the life chart, and negative experiences of health care. Participants frequently provided personal narratives relating to their history of bipolar disorder, life experiences, and backgrounds, which often contained emotive language and humor. They regularly sought and offered advice, and expressed encouragement and empathy. The forum would have benefitted from more users to offer a greater support network with more diverse views and experiences. CONCLUSIONS Online forums are inexpensive to provide and may offer peer support and the opportunity for patients to share their experiences and explore issues related to their illness anonymously. Future research should focus on how to enhance patient engagement with online health care forums.

Abstract
OBJECTIVE To investigate whether those genes involved in the vitamin D pathway modulate the relationship between 25-hydroxyvitamin D (25(OH)D) and IFN-β, the relationship between IFN-β and sun in predicting 25(OH)D, and the interaction between IFN-β and 25(OH)D in modulating relapse risk in patients with MS. METHODS Prospective cohort study of 169 participants with MS and genotype data followed 2002-2005. Gene-IFN-β and gene-IFN-β-sun interactions predicting 25(OH)D evaluated by multilevel mixed-effects linear regression. Gene-IFN-β interactions with 25(OH)D in modulating in relapse risk assessed using survival analysis. RESULTS The cohort was 71.6% female and of mean age 47.8. Two-independent intronic genotyped SNPs (rs10767935 and rs5030244) in WT1 significantly modified the IFN-β-25(OH)D association after adjustment (P(interaction) = 0.001, 0.0002; P(adj) = 0.003, 0.006, respectively). There was a marked difference in the interaction between self-reported sun exposure and IFN-β in predicting 25(OH)D by level of rs10767935, although this did not reach statistical significance. No SNPs modified the interaction between IFN-β and 25(OH)D in predicting relapse. CONCLUSIONS We have demonstrated that two-independent SNPs (rs10767935 and rs5030244) in WT1 modified the IFN-β-25(OH)D association in patients with MS. Some evidence was shown for a difference in the sun-IFN-β-25(OH)D association by level of rs10767935. These findings indicate that WT1 variants may play a role in altering the effects of IFN-β on vitamin D in MS.

Mechanisms of change within motivational interviewing in relation to health behaviors outcomes: a systematic review. PATIENT EDUCATION AND COUNSELING 2015; 98:401-11. [PMID: 25535015 DOI: 10.1016/j.pec.2014.11.022] [Citation(s) in RCA: 90] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/27/2014] [Revised: 10/08/2014] [Accepted: 11/25/2014] [Indexed: 05/15/2023]
Abstract
OBJECTIVE Motivational interviewing (MI) has been identified as an effective treatment for health behaviors. Understanding the mechanisms of MI could have practical implications for MI delivery. This review is the first to examine mechanisms within MI that affect health behavior outcomes and summarizes and evaluates the evidence. METHODS A systematic literature search was conducted in PSYCHINFO, MEDLINE and EMBASE to identify studies that delivered individual MI in the context of health behaviors, excluding addictions, and investigated mechanisms of MI. Effect sizes were calculated. RESULTS 291 studies were identified and 37 met the inclusion criteria. Few of the 37 studies included, conducted mediation analyses. MI spirit and motivation were the most promising mechanisms of MI. Although self-efficacy was the most researched, it was not identified as a mechanism of MI. Study quality was generally poor. CONCLUSION Although this review has indicated possible mechanisms by which MI could influence health behavior outcomes, it also highlights that more high quality research is needed, looking at other possible mechanisms or causal pathways within health behavior outcomes. PRACTICE IMPLICATIONS MI spirit possibly plays an important role within MI and may potentially be used to evoke change talk which links to outcomes.

Abstract
BACKGROUND The burden of childhood respiratory illness is large in low and middle income countries (LMICs). Infant lung function (ILF) testing may provide useful information about lung growth and susceptibility to respiratory disease. However, ILF has not been widely available in LMICs settings where the greatest burden of childhood respiratory disease occurs. AIM To implement and evaluate a pilot study of ILF testing in a semi-rural setting in South Africa. METHOD Infant lung function testing was established at a community hospital in South Africa. All measures were done in unsedated infants during sleep. Measurements, made with the infant quietly breathing through a face mask and bacterial filter, included tidal breathing (TBFVL), exhaled nitric oxide (eNO), and sulphur hexafluoride multiple breath washout (MBW) measures using an ultrasonic flow meter and chemoluminescent NO analyzer. RESULTS Twenty infants, mean age of 7.7 (SD 2.9) weeks were tested; 8 (40%) were Black African and 12 (60%) were mixed race. Five (25%) infants were preterm. There were 19 (95%) successful TBFVL and NO tests and 18 (90%) successful MBW tests. The mean tidal volume was 30.5 ml (SD 5.9), respiratory rate 50.2 breaths per minute (SD 8.7), and eNO 10.4 ppb (SD 7.3). The mean MBW measures were: functional residual capacity 71 ml (SD 13) and the lung clearance index 7.6 (SD 0.5). The intra-subject coefficient of variations (CV) of lung function measures were similar to published normative data for Caucasian European infants. CONCLUSION In this study we demonstrate that unsedated infant lung function measures of tidal breathing, MBW, and eNO are feasible in a semi-rural African setting with rates comparable to those reported from high income countries.

Abstract
BACKGROUND Among the environmental factors associated with multiple sclerosis (MS) causation, some of the strongest associations are with Epstein-Barr virus (EBV), and to a lesser extent human herpesvirus 6 (HHV6). Associations with clinical course are less conclusive, however. METHODS We evaluated serum anti-EBV-EA-R IgG and anti-HHV6 IgM, and EBV and HHV6 viral load (VL) for their associations with relapse, disability, and progression in disability in a prospective cohort of 198 participants with clinically definite MS. RESULTS Anti-EBV-EA-R IgG was detected in 81.8% of cases at study entry, and titers remained essentially unchanged during the study. Anti-HHV6 IgM was detected in only one participant, and EBV-VL (29%) and HHV6-VL (1.8%) were detected in a minority of samples, and where detected levels were low. Our previously demonstrated association between anti-HHV6 IgG and relapse hazard was not affected by adjustment for parameters of reactivation. We found no evidence that any of the viral markers were associated with disability or progression in disability. In relation to relapse, only EBV-VL was positively associated, although this was strongly influenced by a single individual. CONCLUSION Using a prospective cohort design, we found no convincing evidence that reactivation parameters of EBV or HHV6 were associated with subsequent MS relapse hazard or progression in disability, confirming previous findings, and indicating that herpesvirus reactivation is not an important driver of relapse or disability in this established MS population.
