Excellent hepatitis C virus cure rates despite increasing complexity of people who use drugs: Integrated-Test-stage Treat study final outcomes. J Viral Hepat 2024; 31:66-77. [PMID: 38018328 DOI: 10.1111/jvh.13897] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 08/27/2023] [Accepted: 10/31/2023] [Indexed: 11/30/2023]
Abstract
Achieving hepatitic C virus (HCV) elimination requires linking people who use drugs (PWUD) into care. We report final direct-acting antivirals (DAAs)-based outcomes from the Integrated-Test-stage -Treat (ITTREAT) study. Project ITTREAT (2013-2021), based at an addiction centre, was a 'one-stop' service with innovative linkage to care strategies. Primary outcome was sustained virological response (SVR12) (intention to treat ITT) including whether individuals were recruited in first (period 1) versus last four (period 2 included the COVID-19 pandemic) years of the study. Number recruited were n = 765, mean age 40.9 ± 10.1 years, 78% males, history of current/past injecting drug use (IDU) and alcohol use being 77% and 90%, respectively. Prevalence of a positive HCV PCR was 84% with 19% having cirrhosis. Comparing those recruited in period 2 versus period 1, there was increasing prevalence of IDU, 90% versus 72% (p < .001); homelessness, 67% versus 50% (p < .001); psychiatric diagnosis, 84% versus 50% (p < .001); overdose history 71% versus 31% (p < .001), receiving opioid agonist treatment (OAT) 75% versus 52% (p < .001) and comorbidity 44% versus 25% (p < .001). Of those treated with DAAs (n = 272), ITT SVR rates were 86% (95% CI: 81%-90%), being similar in period 2 versus period 1. Predictors of non-SVR were receiving OAT (OR 0.33, 95% CI: 0.12-0.87, p = .025) and ≥80% adherence (OR 0.01, 95% CI: 0.003-0.041, p < .001). Reinfection rates period 2 versus period 1 (per 100 person-years) were 1.84 versus 1.70, respectively. In the treated cohort, mortality was 15%, being mostly drug-related. Despite increasing complexity of PWUD, high SVR12 rates are achievable with use of OAT and good adherence.

Body mass index and nutritional intake following Elexacaftor/Tezacaftor/Ivacaftor modulator therapy in adults with cystic fibrosis. J Cyst Fibros 2023; 22:1002-1009. [PMID: 37422432 DOI: 10.1016/j.jcf.2023.06.010] [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: 02/02/2023] [Revised: 06/01/2023] [Accepted: 06/25/2023] [Indexed: 07/10/2023]
Abstract
BACKGROUND Elexacaftor/Tezacaftor/Ivacaftor (ETI) modulator therapy is often associated with increased body mass index (BMI) in people with cystic fibrosis (CF). This is thought to reflect improved clinical stability and increased appetite and nutritional intake. We explored the change in BMI and nutritional intake following ETI modulator therapy in adults with CF. METHODS Dietary intake, measured with myfood24®, and BMI were collected from adults with CF at baseline and follow-up as part of an observational study. Changes in BMI and nutritional intake in participants who commenced ETI therapy between time points were assessed. To contextualize findings, we also assessed changes in BMI and nutritional intake between study points in a group on no modulators. RESULTS In the pre and post ETI threapy group (n = 40), BMI significantly increased from 23.0 kg/m2 (IQR 21.4, 25.3) at baseline to 24.6 kg/m2 (IQR 23.0, 26.7) at follow-up (p<0.001), with a median of 68 weeks between time points (range 20-94 weeks) and median duration of ETI therapy was 23 weeks (range 7-72 weeks). There was a significant decrease in energy intake from 2551 kcal/day (IQR 2107, 3115) to 2153 kcal/day (IQR 1648, 2606), p<0.001. In the no modulator group (n = 10), BMI and energy intake did not significantly change between time points (p>0.05), a median of 28 weeks apart (range 20-76 weeks). CONCLUSIONS These findings tentatively suggest that the increase in BMI with ETI therapy may not simply be attributable to an increase in oral intake. Further exploration into the underlying aetiology of weight gain with ETI therapy is needed.

Tritium Beta Spectrum Measurement and Neutrino Mass Limit from Cyclotron Radiation Emission Spectroscopy. PHYSICAL REVIEW LETTERS 2023; 131:102502. [PMID: 37739382 DOI: 10.1103/physrevlett.131.102502] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 06/26/2023] [Accepted: 07/17/2023] [Indexed: 09/24/2023]
Abstract
The absolute scale of the neutrino mass plays a critical role in physics at every scale, from the subatomic to the cosmological. Measurements of the tritium end-point spectrum have provided the most precise direct limit on the neutrino mass scale. In this Letter, we present advances by Project 8 to the cyclotron radiation emission spectroscopy (CRES) technique culminating in the first frequency-based neutrino mass limit. With only a cm^{3}-scale physical detection volume, a limit of m_{β}<155 eV/c^{2} (152 eV/c^{2}) is extracted from the background-free measurement of the continuous tritium beta spectrum in a Bayesian (frequentist) analysis. Using ^{83m}Kr calibration data, a resolution of 1.66±0.19 eV (FWHM) is measured, the detector response model is validated, and the efficiency is characterized over the multi-keV tritium analysis window. These measurements establish the potential of CRES for a high-sensitivity next-generation direct neutrino mass experiment featuring low background and high resolution.

A novel protocol to induce mental fatigue. Behav Res Methods 2023:10.3758/s13428-023-02191-5.

Abstract
Mental fatigue is a commonplace human experience which is the focus of a growing body of research. Whilst researchers in numerous disciplines have attempted to uncover the origins, nature, and effects of mental fatigue, the literature is marked by many contradictory findings. We identified two major methodological problems for mental fatigue research. First, researchers rarely use objective measures of mental fatigue. Instead, they rely heavily on subjective reports as evidence that mental fatigue has been induced in participants. We aimed to develop a task which led to not only a subjective increase in mental fatigue, but a corresponding performance decrement in the mentally fatiguing task as an objective measure. Secondly, current mental fatigue paradigms have low ecological validity - in most prior studies participants have been fatigued with a single repetitive task such as the n-back or Stroop. To move towards a more ecologically valid paradigm, our participants undertook a battery of diverse cognitive tasks designed to challenge different aspects of executive function. The AX-CPT, n-back, mental rotation, and visual search tasks were chosen to challenge response inhibition, working memory, spatial reasoning, and attention. We report results from 45 participants aged 19 to 63 years who completed a two-hour battery comprising four different cognitive tasks. Subjective fatigue ratings and task performance were measured at the beginning and end of the battery. Our novel method resulted in an increase in subjective ratings of fatigue (p < 0.001) and a reduction in task performance (p = 0.008). Future research into mental fatigue may benefit from using this task battery.

Cardiac interoception in patients accessing secondary mental health services: A transdiagnostic study. Auton Neurosci 2023; 245:103072. [PMID: 36709619 DOI: 10.1016/j.autneu.2023.103072] [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: 09/05/2022] [Revised: 12/19/2022] [Accepted: 01/08/2023] [Indexed: 01/15/2023]
Abstract
BACKGROUND Abnormalities in the regulation of physiological arousal and interoceptive processing are implicated in the expression and maintenance of specific psychiatric conditions and symptoms. We undertook a cross-sectional characterisation of patients accessing secondary mental health services, recording measures relating to cardiac physiology and interoception, to understand how physiological state and interoceptive ability relate transdiagnostically to affective symptoms. METHODS Participants were patients (n = 258) and a non-clinical comparison group (n = 67). Clinical diagnoses spanned affective disorders, complex personality presentations and psychoses. We first tested for differences between patient and non-clinical participants in terms of cardiac physiology and interoceptive ability, considering interoceptive tasks and a self-report measure. We then tested for correlations between cardiac and interoceptive measures and affective symptoms. Lastly, we explored group differences across recorded clinical diagnoses. RESULTS Patients exhibited lower performance accuracy and confidence in heartbeat discrimination and lower heartbeat tracking confidence relative to comparisons. In patients, greater anxiety and depression predicted greater self-reported interoceptive sensibility and a greater mismatch between performance accuracy and sensibility. This effect was not observed in comparison participants. Significant differences between patient groups were observed for heart rate variability (HRV) although post hoc differences were not significant after correction for multiple comparisons. Finally, accuracy in heartbeat tracking was significantly lower in schizophrenia compared to other diagnostic groups. CONCLUSIONS The multilevel characterisation presented here identified certain physiological and interoceptive differences associated with psychiatric symptoms and diagnoses. The clinical stratification and therapeutic targeting of interoceptive mechanisms is therefore of potential value in treating certain psychiatric conditions.

A thematic analysis of barriers and facilitators to participant engagement in group exposure and response prevention therapy for obsessive-compulsive disorder. Psychol Psychother 2023; 96:129-147. [PMID: 36302721 PMCID: PMC10092306 DOI: 10.1111/papt.12430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Revised: 07/30/2022] [Accepted: 10/05/2022] [Indexed: 11/29/2022]
Abstract
Exposure and response prevention (ERP) is the gold standard in the treatment of the obsessive-compulsive disorder (OCD). It can be delivered effectively using an individual or group therapy format. Nonetheless, a sizeable proportion of people diagnosed with OCD do not experience OCD symptom remission following ERP. Research suggests that participant engagement with ERP tasks predicts therapy outcomes but there is little consistent evidence across studies on what predicts engagement. A recent meta-analysis of participant engagement in cognitive-behavioral therapy for OCD found that group ERP had a comparatively lower dropout rate than individual ERP. Little is known about participant perceptions of ERP to guide an understanding of how the group therapy format may affect participant engagement. This study conducted a qualitative exploration of what helps or hinders participants' engagement in group ERP. It involved thematic analysis of semi-structured interview data collected at a 6-month follow-up from 15 adults with OCD who took part in group ERP. The study identified five main themes that captured participants' perceived facilitators and barriers to engagement in therapy: 'Group processes', 'Understanding how to overcome OCD', 'Personal relevance', 'Personal circumstances', and 'Attitudes towards ERP', which captured dynamically inter-related barriers and facilitators at the level of the client, therapist, therapy and social environment. Each theme and associated sub-themes are discussed in turn, followed by a consideration of the study's limitations and implications.

Abstract
BACKGROUND Individuals with diabetes mellitus (DM) are known to frequently experience gastrointestinal (GI) symptoms. In contrast, the impact of cystic fibrosis-related diabetes (CFRD) on accentuating GI symptoms in people with cystic fibrosis (pwCF) is unknown. We sought to examine this. METHODS Abdominal symptoms were measured using the validated CF-specific GI symptom questionnaire - CFAbd-Score© - as part of a multicentre cohort study in pancreatic insufficient adults with CF, not on cystic fibrosis transmembrane conductance regulator (CFTR) modulators. The CFAbd-Score total score (0-100pts), its 5 domains, alongside nine specific GI symptoms associated with DM, were compared between the CFRD and non-CFRD groups. RESULTS 27 (31%) and 61 (69%) participants with CF were recruited in the CFRD and non-CFRD groups respectively. Total CFAbd-Score and the two domains: gastroesophageal reflux disease and disorders of appetite were significantly higher in the CFRD group compared to the non-CFRD group (p<0.05), with the mean total CFAbd-Score being 25.4 ± 2.5 and 18.4 ± 1.5 in the CFRD and non-CFRD groups respectively. Among the nine GI symptoms commonly reported as elevated in DM, bloating and nausea were significantly more common in individuals with CFRD compared to those without (p<0.05). CONCLUSIONS Individuals with CFRD overall, have a higher GI symptom burden, according to CFAbd-Scores. Specifically, they experience significantly more bloating and nausea. Close monitoring and further research is needed to better understand and manage GI symptoms in this group.

Abstract
BACKGROUND Hearing voices is a common experience in young people, irrespective of diagnosis. This experience can be associated with distress, self-harm and an increased risk of attempting suicide. However, there are currently no evidence-based interventions which specifically target distressing voice hearing experiences in young people. METHOD This was a service evaluation exploring the engagement, outcomes and experiences of young people who were offered a brief 4-session intervention for distressing voices within a Child and Adolescent Mental Health Service (CAMHS) in the UK's National Health Service. The intervention was based on the principles of Coping Strategy Enhancement (CSE). RESULTS A total of 24 young people were offered the CSE intervention over a 20-month period. The intervention was completed by 15 young people. Pre-post outcomes suggested clinically meaningful reductions in the negative impact of voices for the majority of the young people. Qualitative feedback was positive and highlighted the value of both a space to talk about voice hearing experiences and a focus upon coping strategies. CONCLUSIONS The findings from this service evaluation suggest that CSE can be a brief, acceptable and helpful way for young people within a CAMHS context to start a therapeutic conversation about their distressing voice hearing experiences.

Voice Hearing in Borderline Personality Disorder Across Perceptual, Subjective, and Neural Dimensions. Int J Neuropsychopharmacol 2021; 25:375-386.

Abstract
BACKGROUND Auditory verbal hallucinations (AVH) commonly occur in the context of borderline personality disorder (BPD) yet remain poorly understood. AVH are often perceived by patients with BPD as originating from inside the head and hence viewed clinically as "pseudohallucinations," but they nevertheless have a detrimental impact on well-being. METHODS The current study characterized perceptual, subjective, and neural expressions of AVH by using an auditory detection task, experience sampling and questionnaires, and functional neuroimaging, respectively. RESULTS Perceptually, reported AVH correlated with a bias for reporting the presence of a voice in white noise. Subjectively, questionnaire measures indicated that AVH were significantly distressing and persecutory. In addition, AVH intensity, but not perceived origin (i.e., inside vs outside the head), was associated with greater concurrent anxiety. Neurally, fMRI of BPD participants demonstrated that, relative to imagining or listening to voices, periods of reported AVH induced greater blood oxygenation level-dependent activity in anterior cingulate and bilateral temporal cortices (regional substrates for language processing). AVH symptom severity was associated with weaker functional connectivity between anterior cingulate and bilateral insular cortices. CONCLUSION In summary, our results indicate that AVH in participants with BPD are (1) underpinned by aberrant perceptual-cognitive mechanisms for signal detection, (2) experienced subjectively as persecutory and distressing, and (3) associated with distinct patterns of neural activity that inform proximal mechanistic understanding. Our findings are like analogous observations in patients with schizophrenia and validate the clinical significance of the AVH experience in BPD, often dismissed as "pseudohallucinations." These highlight a need to reconsider this experience as a treatment priority.

Interoceptive training to target anxiety in autistic adults (ADIE): A single-center, superiority randomized controlled trial. EClinicalMedicine 2021; 39:101042. [PMID: 34401684 PMCID: PMC8350004 DOI: 10.1016/j.eclinm.2021.101042] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 07/01/2021] [Accepted: 07/09/2021] [Indexed: 01/26/2023] Open
Abstract
BACKGROUND This trial tested if a novel therapy, Aligning Dimensions of Interoceptive Experience (ADIE), reduces anxiety in autistic adults. ADIE targets the association of anxiety with mismatch between subjective and behavioral measures of an individual's interoceptive sensitivity to bodily signals, including heartbeats. METHODS In this superiority randomized controlled trial, autistic adults (18-65 years) from clinical and community settings in Southern England were randomly assigned (1:1) to receive six sessions of ADIE or an active 'exteroceptive' control therapy (emotional prosody identification). Researchers conducting outcome assessments were blind to allocation. ADIE combines two modified heartbeat detection tasks with performance feedback and physical activity manipulation that transiently increases cardiac arousal. Participants were followed-up one-week (T1) and 3-months post-intervention (T2). The primary outcome was Spielberger Trait Anxiety Score (STAI-T) at T2. Outcomes were assessed on an intention-to-treat basis using multiple imputation for dealing with missing values. This trial was registered at International Standard Randomized Controlled Trial Registry, ISRCTN14848787. FINDINGS Between July 01, 2017, and December 31, 2019, 121 participants were randomly allocated to ADIE (n = 61) or prosody (n = 60) intervention groups. Data at T1 was provided by 85 (70%) participants (46 [75%] ADIE; 39 [65%] prosody). Data at T2 was provided by 61 (50%) participants (36 [59%] ADIE; 25 [42%] prosody). One adverse event (cardiac anxiety following ADIE) was recorded. A statistically significant group effect of ADIE on trait anxiety continued at T2 (estimated mean difference 3•23 [95% CI 1•13 to 5•29]; d = 0•30 [95% CI 0•09 to 0•51]; p = 0•005) with 31% of ADIE group participants meeting trial criteria for recovery (compared to 16% in the control group). INTERPRETATION ADIE can reduce anxiety in autistic adults, putatively improving regulatory control over internal stimuli. With little reliance on language and emotional insight, ADIE may constitute an inclusive intervention. FUNDING MQ Transforming Mental Health PsyImpact Grant.

A cross-sectional study of auditory verbal hallucinations experienced by people with a diagnosis of borderline personality disorder. Clin Psychol Psychother 2021; 29:631-641. [PMID: 34322956 DOI: 10.1002/cpp.2655] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2021] [Revised: 07/15/2021] [Accepted: 07/19/2021] [Indexed: 11/09/2022]
Abstract
BACKGROUND The presence of auditory verbal hallucinations (AVHs) does not currently feature in the main diagnostic criteria for borderline personality disorder (BPD). However, there is accumulating evidence that a high proportion of BPD patients report longstanding and frequent AVHs which constitute a significant risk factor for suicide plans and attempts, and hospitalization. AIM This study addressed questions about the validity and phenomenology of AVHs in the context of BPD. The longer-term aim is to facilitate the development and translation of treatment approaches to address the unmet need of this population. METHOD This was a cross-sectional study, combining phenomenological and psychological assessments administered in person and online. We explored the experiences of 48 patients with a diagnosis of BPD who were hearing AVHs. RESULTS Participants gave 'consistent' reports on the measure of AVH phenomenology, suggesting that these experiences were legitimate. Similar to AVHs in a psychosis context, AVHs were experienced as distressing and appraised as persecutory. AVHs were found to be weakly associated with BPD symptoms. AVHs were also rated highly as a treatment priority by the majority of participants. CONCLUSION The findings suggest that AVH is a legitimate and distressing symptom of BPD and a treatment priority for some patients. The relative independence of AVHs from other BPD symptoms and emotional states suggests that psychological treatment may need to be targeted specifically at the symptom of AVHs. This treatment could be adapted from cognitive behaviour therapy, the psychological intervention that is recommended for the treatment of AVHs in the context of psychosis.

Brief coping strategy enhancement for the treatment of distressing voices in the context of borderline personality disorder: A comparison with outcomes in the context of psychosis. Clin Psychol Psychother 2021; 29:567-578. [PMID: 34255401 DOI: 10.1002/cpp.2647] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Revised: 05/21/2021] [Accepted: 06/28/2021] [Indexed: 11/07/2022]
Abstract
BACKGROUND Voice hearing in the context of Borderline Personality Disorder (BPD) has traditionally been regarded as transient and an experience that lacks legitimacy. Consequently, there are no evidence-based treatments for the voices reported by BPD patients. Contrary to the traditional view, there is a growing literature suggesting that voice hearing in the context of BPD can be an enduring and distressing experience which shares similarities with voice hearing in the context of psychosis. Given these similarities, the aim of this study was to explore whether brief Coping Strategy Enhancement developed in the context of psychosis can be used to treat distressing voice hearing in the context of BPD. METHOD This was a service evaluation carried out in a specialist NHS service delivering psychological therapies for distressing voices. Patients with either a BPD (n = 46) or a psychosis diagnosis (n = 125) received four sessions of Coping Strategy Enhancement (CSE). The primary outcome was voice-related distress. The pre-post outcomes for BPD patients were explored and compared with those achieved by the psychosis patients. RESULTS Both the BPD and psychosis groups experienced a significant reduction in voice-related distress after CSE compared with baseline. The interaction between diagnosis group and time was small and statistically non-significant. CONCLUSION These findings suggest a brief CSE intervention developed in the context of psychosis can be an effective starting point in the treatment of distressing voice hearing in the context of BPD. Such interventions have the potential to be integrated into broader BPD treatment programmes for those who hear voices.

Abstract
Background Relationship status is an important factor associated with condomless anal intercourse (CAI) amongst men who have sex with men (MSM). Methods A multi-centre bio-behavioural survey with MSM was conducted in 13 European cities (n = 4901) exploring factors associated with CAI via bivariate and multivariate multilevel logistic regression analyses. Results Likelihood of CAI with casual partners was associated with being ‘out’ to a majority (AOR = 1.19;95% CI 1,1.42); knowing their HIV status (AOR = 1.86; 95% CI 1.25,2.76); using substances (1–2 AOR = 1.39; 95% CI 1.16,1.63, 2+ AOR = 1.81; 95% CI 1.35,2.42); being older (AOR = 0.98; 95% CI 0.97,0.99); successful sero-communication (AOR = 0.79; 95% CI 0.67,0.94); and, not having a recent HIV test (AOR = 0.78; 95% CI 0.66,0.92). CAI with steady partners was associated with successful sero-communication (AOR = 2.72; 95% CI 2.72,3.66); not having a recent HIV test (AOR = 1.26; 95% CI 1.09,1.46), and; being older (AOR = 0.99; 95% CI 0.98,0.99). Conclusions Understandings of partner type and/or relationship status in relation to CAI amongst MSM can potentially play an important role in the development of culturally appropriate HIV/STI prevention and risk-reduction efforts targeting at-risk MSM. Our results speak to the need to consider segmented and tailored public health and health promotion initiatives for MSM with differing CAI behaviours and relationship profiles.

Abstract
BACKGROUND Fibromyalgia and myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) are poorly understood conditions with overlapping symptoms, fuelling debate as to whether they are manifestations of the same spectrum or separate entities. Both are associated with hypermobility, but this remains significantly undiagnosed, despite impact on quality of life. OBJECTIVE We planned to understand the relevance of hypermobility to symptoms in fibromyalgia and ME/CFS. METHOD Sixty-three patient participants presented with a confirmed diagnosis of fibromyalgia and/or ME/CFS; 24 participants were healthy controls. Patients were assessed for symptomatic hypermobility. RESULTS Evaluations showed exceptional overlap in patients between fibromyalgia and ME/CFS, plus 81% met Brighton criteria for hypermobility syndrome (odds ratio 7.08) and 18% met 2017 hypermobile Ehlers-Danlos syndrome (hEDS) criteria. Hypermobility scores significantly predicted symptom levels. CONCLUSION Symptomatic hypermobility is particularly relevant to fibromyalgia and ME/CFS, and our findings highlight high rates of mis-/underdiagnosis. These poorly understood conditions have a considerable impact on quality of life and our observations have implications for diagnosis and treatment targets.

Exploring the Development, Validity, and Utility of the Short-Form Version of the CHoice of Outcome In Cbt for PsychosEs: A Patient-Reported Outcome Measure of Psychological Recovery. Schizophr Bull 2020; 47:653-661. [PMID: 33215190 PMCID: PMC8084424 DOI: 10.1093/schbul/sbaa173] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/13/2022]
Abstract
The original CHoice of Outcome In Cbt for psychosEs (CHOICE) measure was designed in collaboration with experts by experience as a patient-reported "Psychological Recovery" outcome measure for cognitive-behavioral therapy for psychosis (CBTp). A short version (CHOICE-SF) was developed to use as a brief outcome measure, with a focus on sensitivity to change, for use in future research and practice. CHOICE-SF was developed and validated using 3 separate samples, comprising 640 service users attending 1 of 2 transdiagnostic clinics for (1) CBTp or (2) therapies for voice hearing or (3) who took part in the treatment as usual arm of a trial. In the initial subsample of 69 participants, items from the original CHOICE measure with medium to large effect sizes for change pre- to post-CBTp were retained to form the CHOICE-SF. Internal consistency, construct validity, and sensitivity to change were confirmed, and the factor structure was examined in 242 participants. Specificity was confirmed by comparison with 44 participants who completed CHOICE at 2 time points but did not receive therapy. Validation of CHOICE-SF was carried out by confirming factor structure and sensitivity to change in a new sample of 354 and a subsample of 51 participants, respectively. The CHOICE-SF comprised 11 items and 1 additional personal goal item. A single-factor structure was confirmed, with high internal consistency, construct validity, and sensitivity to change. The CHOICE-SF is a brief, psychometrically robust measure to assess change following psychological therapies in research and clinical practice for people with psychosis and severe mental illness.

Participant perspectives on the acceptability and effectiveness of mindfulness-based cognitive behaviour therapy approaches for obsessive compulsive disorder. PLoS One 2020; 15:e0238845. [PMID: 33085672 PMCID: PMC7577499 DOI: 10.1371/journal.pone.0238845] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2020] [Accepted: 08/25/2020] [Indexed: 01/13/2023] Open
Abstract
Cognitive behavioural therapy (CBT) which includes Exposure and Response (ERP) is a highly effective, gold standard treatment for Obsessive-Compulsive Disorder (OCD). Nonetheless, not all patients with OCD significantly benefit from CBT. This has generated interest in the potential benefits of Mindfulness-Based Interventions (MBIs), either integrated with CBT, to enhance engagement with ERP tasks, or delivered as a stand-alone, first-line or therapy to augment CBT. This paper reports on two qualitative studies that involved a thematic analysis of interview data with participants in a 10-week Mindfulness-Based ERP (MB-ERP) course (study 1) and a 9-week Mindfulness-Based Cognitive Therapy course adapted for OCD (MBCT-OCD) (study 2). Whilst MB-ERP integrated a mindfulness component into a standard ERP protocol, MBCT-OCD adapted the psychoeducational components of the standard MBCT for depression protocol to suit OCD, but without explicit ERP tasks. Three common main themes emerged across MB-ERP and MBCT-OCD: 'satisfaction with course features', 'acceptability of key therapeutic tasks 'and 'using mindfulness to respond differently to OCD'. Sub-themes identified under the first two main themes were mostly unique to MB-ERP or MBCT-OCD, with the exception of '(struggles with) developing a mindfulness practice routine' whilst most of the sub-themes under the last main theme were shared across MB-ERP and MBCT-OCD participants. Findings suggested that participants generally perceived both MBIs as acceptable and potentially beneficial treatments for OCD, in line with theorised mechanisms of change.

Abstract
Background Gout has been associated with weaker foot/leg muscles and altered gait patterns. There is also evidence of on-going foot pain and an increased risk of tendinopathy, with the Achilles and patella tendons most frequently affected in gout. Additionally, the inflammation associated with gout may change tissue elasticity. Ultrasound imaging utilising shear wave elastography (SWE) offers a non-invasive method of quantifying changes in tendon stiffness. SWE findings have not previously been reported in individuals with gout. We sought to determine differences in Achilles tendon stiffness in people with gout compared to controls (non-gout). Methods A cross sectional study comparing 24 people with gout and 26 age/sex-matched controls. Clinical and demographic data were collated, and US imaging used to determine tendon thickness, presence of gouty tophi and/or aggregates and levels of angiogenesis. Ten shear wave elastography (SWE) measures were taken along the centre of a longitudinal section of the mid-portion of each Achilles tendon. Prior to data collection, intra-observer error was good (>0.69). Data were summarised using descriptive statistics and a repeated measures ANCOVA was used to compare SWE measures between the two groups for the left and right foot separately after accounting for Body Mass Index (BMI). Results A small proportion of those with gout presented with intra-tendon aggregates and/or intra-tendon tophi in one or both tendons. There was no statistically significant difference in tendon thickness between groups. Neo-vascularity was present in a third of gout participants. SWE findings demonstrated significantly reduced tendon stiffness in those with gout compared to controls: right Achilles mdiff =1.04 m/s (95% CI (0.38 to 1.7) p = 0.003 and left Achilles mdiff = 0.7 m/s (95% CI 0.09 to 1.32) p = 0.025. No relationship between the presence of tophi and SWE values were detected. Conclusion Subjects with chronic gout show significantly reduced Achilles tendon stiffness compared to non-gout controls. From a clinical standpoint, our findings were similar to SWE measurements in subjects with Achilles tendinopathy and who did not have gout.

Abstract
Abdominal pain is a common feature in patients with cystic fibrosis (CF) and CF related liver disease (CFLD). Superior mesenteric venous (SMV) thrombosis is an uncommon but important cause of abdominal pain. Management strategies are complicated by an underlying prothrombotic state and increased risk of bleeding from complications of CF and CFLD. This review addresses clinical presentation, detection and management options of an acute SMV thrombus in the context of CF.

Abstract
OBJECTIVE To investigate different types of parent-child conversations associated with young people's (13-17 years) alcohol-related risk behaviours. DESIGN Secondary analysis of the 2016 Drinkaware Monitor Survey. This survey employed a cross-sectional design and collected data using self-completion questionnaires. SETTING UK-wide. PARTICIPANTS 561 parent-child pairs were included in the analysis. The nationally representative quota sample was weighted by reference to the UK population. METHODOLOGY Data were analysed using purposeful selection modelling (adjusted OR (AOR), 95% CIs). RISK BEHAVIOURS: 'Whether have ever drank' and 'whether vomited as a result of alcohol'. RESULTS 50% (277/553) of young people reported drinking a whole alcoholic drink, and 22% (60/277) of these experienced vomiting as a result. After adjusting for age and gender, the likelihood of ever having drank alcohol was significantly increased among the following young people: those whose parents believed they knew a little about how much they drink (AOR 1.80, 95% CI 1.04 to 3.13) or that some/most/all friends drink (AOR 3.82, 95% CI 2.40 to 6.08); those given gentle reminders about taking care when drinking alcohol (AOR 1.82, 95% CI 1.15 to 2.88), practical advice (AOR 2.09, 95% CI 1.20 to 3.64) or designated time, led by the parent, to instil care around alcohol through a formal sit-down (AOR 1.79, 95% CI 1.07 to 2.99). The likelihood was reduced for parents aged 40-49 years (AOR 0.52, 95% CI 0.31 to 0.89) and conversations providing information (AOR 0.53, 95% CI 0.29 to 0.98). Vomiting was significantly associated with some/most/all friends drinking alcohol (AOR 3.65, 95% CI 1.08 to 12.30), parent's beliefs about child's frequency of drinking alcohol (AOR 1.26, 95% CI 1.02 to 1.54), parental harmful/dependency drinking (AOR 3.75, 95% CI 1.13 to 12.50) and having a formal sit-down conversation (AOR 2.15, 95% CI 0.99 to 4.66). CONCLUSIONS We found evidence of mostly negative associations between young people's risk behaviours and different types of parent-child conversations. Conversations providing information were linked to a reduced tendency to have ever drunk alcohol. All other types of conversations were negatively associated with risk behaviours. Psychological reactance and conversation quality possibly explain these findings.

Abstract
Introduction
A BMI increase, in men and women, is associated with an increased severity and progression of OSA. This study will examine the impact of BMI on varying levels of OSA severity and progression.
Methods
Participants, divided by sex, included 2728 (47%) men and 3076 (53%) women over the age of 40 that were in the Sleep Heart Health Study (SHHS). Participants were separated into 1 of 10 groups based on initial OSA levels at SHHS time point 1 (SHHS1) and ending OSA levels at SHHS time point 2 (SHHS2) as measured by RDI. A Kruskall-Wallis test examined the BMI median differences in the groups. Post-hoc tests, including pairwise comparisons and Wilcoxon rank sum test with Holm adjustment, were conducted to further examine results.
Results
Significant differences existed between certain groups (Men: Chi-Square=146.87, p<.001, df=9; Women: Chi-Square=128.59, p<.001, df=9). For men and women, those in the group with normal OSA levels at SHHS1 and SHHS2 had significant BMI differences compared to those in all 9 other groups where mild, moderate, or severe OSA levels exist at SHHS1 or SHHS2. Additionally, in men, BMI is significantly different for those with normal or mild OSA levels at SHHS2 compared to those with moderate or severe OSA levels at SHHS2. Also, a significant BMI difference exists in men maintaining mild OSA levels throughout SHHS compared to those maintaining severe OSA levels.
Conclusion
Although BMI is a known influential factor in OSA progression, this study demonstrated that those maintaining normal OSA levels over time have a significant BMI difference compared to those reaching even mild OSA levels over time. Additional implications were also found for men. These findings may coincide with recent research suggesting that one needs to progress only to moderate OSA levels to reach a tipping point of significantly increasing and impacting many health risks.

Low-Intensity Guided Help Through Mindfulness (LIGHTMIND): study protocol for a randomised controlled trial comparing supported mindfulness-based cognitive therapy self-help to supported cognitive behavioural therapy self-help for adults experiencing depression. Trials 2020; 21:374.

Abstract
Background Depression has serious personal, family and economic consequences. It is estimated that it will cost £12.15 billion to the economy each year in England by 2026. Improving access to psychological therapies (IAPT) is the National Health Service talking therapies service in England for adults experiencing anxiety or depression. Over 1 million people are referred to IAPT every year, over half experiencing depression. Where symptoms of depression are mild to moderate, people are typically offered cognitive behavioural therapy (CBT) self-help (CBT-SH) supported by a psychological well-being practitioner. The problem is that over half of people who complete treatment for depression in IAPT remain depressed despite receiving National Institute of Health and Care Excellent recommended treatment. Furthermore, less than half of IAPT service users complete treatment. This study seeks to investigate the effectiveness of an alternative to CBT-SH. Mindfulness-based cognitive therapy (MBCT) differs from CBT in focus, approach and practice, and may be more effective with a higher number of treatment completions. Methods/design This is a definitive randomised controlled trial comparing supported MBCT self-help (MBCT-SH) with CBT-SH for adults experiencing mild to moderate depression being treated in IAPT services. We will recruit 410 participants experiencing mild to moderate depression from IAPT services and randomise these to receive either an MBCT-based self-help workbook or a CBT-based self-help workbook. Participants will be asked to complete their workbook within 16 weeks, with six support sessions with a psychological well-being practitioner. The primary outcome is depression symptom severity on treatment completion. Secondary outcomes are treatment completion rates and measures of generalized anxiety, well-being, functioning and mindfulness. An exploratory non-inferiority analysis will be conducted in the event the primary hypothesis is not supported. A semi-structured interview with participants will guide understanding of change processes. Discussion If the findings from this randomised controlled trial demonstrate that MBCT-SH is more effective than CBT-SH for adults experiencing depression, this will provide evidence for policy makers and lead to changes to clinical practice in IAPT services, leading to greater choice of self-help treatment options and better outcomes for service users. If the exploratory non-inferiority analysis is conducted and this indicates non-inferiority of MBCT-SH in comparison to CBT-SH this will also be of interest to policy makers when seeking to increase service user choice of self-help treatment options for depression.

Abstract
BACKGROUND/AIMS Direct-acting antivirals (DAAs) provide an unprecedented opportunity for a "find-and-treat strategy." We aimed to report real-world clinical, patient reported and health economic outcomes of community-based hepatitis C virus (HCV) screening/treatment in people who use drugs (PWUDs). METHODS Project ITTREAT (2013-2021), established at a drug and alcohol treatment centre, offered a comprehensive service. Generic (SF-12v2 and EQ-5D-5L) and liver-specific (SFLDQoL) health-related quality of life (HRQoL) were assessed before and after HCV treatment. Costs/case detected and cured were calculated. Primary outcome measure was sustained virological response (SVR) (intention to treat). RESULTS Till March 2018, 573 individuals recruited, 462 (81%) males, mean age 40.5 ± 10.0 years. Of the 125 treated, 115 (92%) had past/current history of injecting drug use, 88 (70%) were receiving opioid agonist treatment and 50 (40%) were homeless. Twenty-six per cent received interferon-based and 74% DAA-only regimens. SVR (ITT) was 87% (90% with DAAs). Service uptake/HCV treatment completion rates were >95%, HCV reinfection being 2.63/100 person years (95% CI 0.67-10.33). HRQoL improved significantly at end of treatment (EOT) in those with SVR: SFLDQoL (symptoms, memory, distress, loneliness, hopelessness, sleep and stigma) (P</ = .011); SF-12 v2 physical and mental health domains (P < .001); and EQ-5D-5L composite profile score (P = .009) and visual analogue scale, P < .001. Cost (British pounds 2018) per case detected was £171; mean cost per cure (excluding medication) was £702 ± 188. CONCLUSIONS Excellent real-world SVRs in PWUDs with significant improvement in HRQoL can be achieved at modest costs. Project ITTREAT endorses community-based integrated services to help achieve HCV elimination.

Abstract
Brief and single-symptom forms of cognitive behaviour therapy (CBT) for distressing voices may increase access to evidence-based psychological therapy and transcend diagnostic barriers. The current study evaluated the "C" and "B" in CBT for distressing voices in a transdiagnostic voices clinic. The B module (component of therapy) sought to enhance coping with voices, and the C module evaluated the accuracy of negative beliefs about the self and voices. The aims of the study were to investigate (a) whether modules B and/or C led to significant and clinically meaningful improvements on the primary outcome of voice-related distress, and (b) if changes in beliefs about self and voices (proposed change mechanisms) underpinned changes in voice distress across module C. Each module consisted of four sessions, individually tailored yet manualized, and designed with ease of staff training and delivery in mind. Assessment measures were administered at baseline (T1), post-module B (T2), and post-module C (T3). The results (N = 62) showed statistically significant medium-sized pre- and post-effects for voice-related distress from T1 to T2 and from T2 to T3, with large effects from T1 to T3. Just over half of the clients reported clinically meaningful improvements from T1 to T3. Neither beliefs about self nor voices were found to mediate improvements in voice distress during module C. The findings from this study suggest that both the B and C in CBT for voices can contribute to positive outcomes within routine clinical practice.

Abstract
This research was conducted in response to governmental and public concern regarding the escalating use of section 136 of the Mental Health Act (1983) nationally and of the excessive use of police custody as a place of safety in Sussex in particular. A retrospective analysis of all detentions in Sussex during 2012 was combined with qualitative data from 37 people with lived experience of detention, as well as police, National Health Service (NHS) and allied staff and volunteers. Predominantly, police used s136 as suicide prevention (80%) when no other services or help were available. During the period of study (2013-2016), effective joint working strategies, such as the street triage pilot, were able to reduce the overall rates of s136 detentions and to increase access to NHS place of safety suites markedly. Although the research acknowledges idiosyncratic local factors which contribute to the high rate of detentions across Sussex, the results have wider implications for national policy and practice.

Abstract
Beneficial modulation of the gut microbiota is an attractive therapeutic approach to improve the efficacy of vaccine-induced immunity. In this study, mice were supplemented with the prebiotic milk oligosaccharide 2'-fucosyllactose (2'FL) as well as a complex mixture of immune modulatory prebiotic short-chain galacto-oligosaccharides and long-chain fructo-oligosaccharides (scGOS/lcFOS) from different stages in early life. Adult mice were vaccinated with trivalent influenza vaccine (TIV) and both development of the gut microbiota and antibody-mediated vaccine responses were followed over time. Within the control group, female mice demonstrated a larger antibody response to TIV vaccination than male mice, which was accompanied by enhanced cytokine production by splenocytes and a higher percentage of plasma cells in skin draining lymph nodes. In addition, the prebiotic diet improved vaccine-specific antibody responses in male mice. Introduction of prebiotics into the diet modulated the gut microbiota composition and at the genus level several bacterial groups showed a significant interaction effect which potentially contributed to the immunological effects observed. This study provides insight in the effect of scGOS/lcFOS/2'FL in influenza vaccination antibody production.

Abstract
BACKGROUND Only about half of people with obsessive compulsive disorder (OCD) show clinically significant improvement following the recommended therapy, exposure and response prevention (ERP), partly due to poor therapy acceptability. A mindfulness-based approach to ERP (MB-ERP) has the potential to improve acceptability and outcomes. METHODS This was an internal pilot randomised controlled trial (RCT) of group MB-ERP compared to group ERP. 37 participants meeting DSM-IV OCD criteria were randomly allocated to MB-ERP or ERP. RESULTS Both groups improved in OCD symptom severity. However, MB-ERP did not lead to clinically important improvements in OCD symptom severity at post-intervention compared to ERP - the minimum clinically important difference was not contained in the 95% confidence intervals. There were negligible between-group differences in engagement and MB-ERP did not appear to have broader benefits compared to ERP on depression, wellbeing or OCD-related beliefs. Conversely, MB-ERP led to medium/medium-large improvements in mindfulness compared to ERP. CONCLUSIONS MB-ERP is unlikely to lead to clinically meaningful improvements in OCD symptom severity compared to ERP alone. We underline the importance of adhering to treatment guidelines recommending ERP for OCD. Insufficient attention may have been given to mindfulness practice/discussion in MB-ERP and further research is recommended to explore this possibility.

Abstract
Cognitive behaviour therapy is recommended internationally as a treatment for psychosis (targeting symptoms such as auditory hallucinations, or "voices"). Yet mental health services are commonly unable to offer such resource-intensive psychological interventions. Brief, symptom-specific and less resource-intensive therapies are being developed as one initiative to increase access. However, as access increases, so might the risk of offering therapy to clients who are not optimally disposed to engage with and benefit from therapy. Thus, it is important to identify who is most/least likely to engage with and benefit from therapy, and when. In the current study, 225 clients were assessed for suitability for a brief, 4-session, manualized, cognitive behaviour therapy-based intervention for voices (named coping strategy enhancement therapy) and 144 commenced therapy, at a transdiagnostic voices clinic based in Sussex, UK. This article reports on the value of depression, anxiety, stress, insight into the origin of voices, length of voice hearing, and demographics in the prediction of engagement and outcomes. The study found that higher levels of baseline depression, anxiety, and stress were significantly associated with poorer outcomes, especially if clients also had high levels of voice-related distress. The engagement analyses showed that levels of voice-related distress at baseline predicted dropout. These findings highlight the importance of assessing negative affect and voice-related distress prior to commencing therapy for distressing voices, to help determine if the client is suitable or ready for brief-coping strategy enhancement.

Abstract
The experience of hearing voices (‘auditory hallucinations’) can cause significant distress and disruption to quality of life for people with a psychosis diagnosis. Psychological therapy in the form of cognitive behavior therapy (CBT) for psychosis is recommended for the treatment of positive symptoms, including distressing voices, but is rarely available to patients in the United Kingdom. CBT for psychosis has recently evolved with the development of symptom-specific therapies that focus upon only one symptom of psychosis at a time. Preliminary findings from randomized controlled trials suggest that these symptom-specific therapies can be more effective for distressing voices than the use of broad CBT protocols, and have the potential to target voices trans-diagnostically. Whilst this literature is evolving, consideration must be given to the potential for a symptom-specific approach to overcome some of the barriers to delivery of evidence-based psychological therapies within clinical services. These barriers are discussed in relation to the United Kingdom mental health services, and we offer suggestions for future research to enhance our understanding of these barriers.

Prevalence of drug use during sex amongst MSM in Europe: Results from a multi-site bio-behavioural survey. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2018; 55:231-241. [PMID: 29402683 DOI: 10.1016/j.drugpo.2018.01.002] [Citation(s) in RCA: 44] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2017] [Revised: 12/23/2017] [Accepted: 01/04/2018] [Indexed: 11/29/2022]
Abstract
BACKGROUND Substance use has been consistently reported to be more prevalent amongst Men who have Sex with Men (MSM) compared to the general population. Substance use, in particular polydrug use, has been found to be influenced by social and contextual factors and to increase the risk of unprotected intercourse among MSM. The objective of this analysis was to investigate the prevalence and predictors of drug use during a sexual encounter and to identify specific prevention needs. METHODS/DESIGN A multi-site bio-behavioural cross-sectional survey was implemented in 13 European cities, targeting MSM and using Time-Location Sampling and Respondent-Driven Sampling methods Multivariable multi-level logistic random-intercept model (random effect of study site) was estimated to identify factors associated with the use of alcohol, cannabis, party drugs, sexual performance enhancement drugs and chemsex drugs. RESULTS Overall, 1261 (30.0%) participants reported drug use, and 436 of 3706 (11.8%) reported the use of two or more drugs during their last sexual encounter. By drug class, 966 (23.0%) reported using sexual performance enhancement drugs, 353 (8.4%) - party drugs, and 142 (3.4%) the use of chemsex drugs. Respondents who reported drug use were more frequently diagnosed with HIV (10.5% vs. 3.9%) before and with other STIs during the 12 months prior to the study (16.7% vs. 9.2%). The use of all the analysed substances was significantly associated with sexual encounter with more than one partner. DISCUSSION Substance and polydrug use during sexual encounters occurred amongst sampled MSM across Europe although varying greatly between study sites. Different local social norms within MSM communities may be important contextual drivers of drug use, highlighting the need for innovative and multi-faceted prevention measures to reduce HIV/STI risk in the context of drug use.

Guided self-help cognitive-behaviour Intervention for VoicEs (GiVE): Results from a pilot randomised controlled trial in a transdiagnostic sample. Schizophr Res 2018; 195:441-447. [PMID: 29033279 DOI: 10.1016/j.schres.2017.10.004] [Citation(s) in RCA: 43] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2017] [Revised: 09/29/2017] [Accepted: 10/06/2017] [Indexed: 02/01/2023]
Abstract
BACKGROUND Few patients have access to cognitive behaviour therapy for psychosis (CBTp) even though at least 16 sessions of CBTp is recommended in treatment guidelines. Briefer CBTp could improve access as the same number of therapists could see more patients. In addition, focusing on single psychotic symptoms, such as auditory hallucinations ('voices'), rather than on psychosis more broadly, may yield greater benefits. METHOD This pilot RCT recruited 28 participants (with a range of diagnoses) from NHS mental health services who were distressed by hearing voices. The study compared an 8-session guided self-help CBT intervention for distressing voices with a wait-list control. Data were collected at baseline and at 12weeks with post-therapy assessments conducted blind to allocation. Voice-impact was the pre-determined primary outcome. Secondary outcomes were depression, anxiety, wellbeing and recovery. Mechanism measures were self-esteem, beliefs about self, beliefs about voices and voice-relating. RESULTS Recruitment and retention was feasible with low study (3.6%) and therapy (14.3%) dropout. There were large, statistically significant between-group effects on the primary outcome of voice-impact (d=1.78; 95% CIs: 0.86-2.70), which exceeded the minimum clinically important difference. Large, statistically significant effects were found on a number of secondary and mechanism measures. CONCLUSIONS Large effects on the pre-determined primary outcome of voice-impact are encouraging, and criteria for progressing to a definitive trial are met. Significant between-group effects on measures of self-esteem, negative beliefs about self and beliefs about voice omnipotence are consistent with these being mechanisms of change and this requires testing in a future trial.

Effects of montmorency tart cherry (L. Prunus Cerasus) consumption on nitric oxide biomarkers and exercise performance. Scand J Med Sci Sports 2018; 28:1746-1756.

Abstract
The purpose of this study was to investigate the effects of Montmorency tart cherry juice (MC) on nitric oxide (NO) biomarkers, vascular function, and exercise performance. In a randomized, double-blind, placebo (PLA)-controlled, crossover study, 10 trained cyclists (mean ± SD; V˙O2peak 59.0 ± 7.0 mL/kg/min) acutely ingested 30 mL of either MC or PLA following dietary restrictions of polyphenol-rich compounds and completed 6-minutes moderate- and severe-intensity cycling bouts 1.5 hour post-ingestion on 2 occasions for each experimental condition. The severe-intensity cycling test was continued to exhaustion on 1 occasion and immediately followed by a 60-seconds all-out sprint on the other occasion. Blood pressure, pulse wave measures, tissue oxygenation index, and plasma nitrite concentration were assessed pre- and 1.5 hour post-ingestion. Time to exhaustion was not different between conditions (P > .05), but peak power over the first 20 seconds (363 ± 42 vs 330 ± 26 W) and total work completed during the 60-seconds all-out sprint (21 ± 3 vs 19 ± 3 kJ) were 10% higher in the MC trial compared to the PLA trial (P < .05). Systolic blood pressure was 5 ± 2 mm Hg lower 1.5 hour post-MC supplementation compared to PLA supplementation (P < .05). There were no differences in pulse wave measures, plasma nitrite concentration, or tissue oxygenation between the MC and PLA trials (P > .05). These results suggest that acute supplementation with MC can lower blood pressure and improve some aspects of exercise performance, specifically end-sprint performance, in trained cyclists.

HIV serostatus knowledge and serostatus disclosure with the most recent anal intercourse partner in a European MSM sample recruited in 13 cities: results from the Sialon-II study. BMC Infect Dis 2017; 17:730.

Abstract
Background Knowledge of HIV status can be important in reducing the risk of HIV exposure. In a European sample of men-who-have-sex-with-men (MSM), we aimed to identify factors associated with HIV serostatus disclosure to the most recent anal intercourse (AI) partner. We also aimed to describe the impact of HIV serostatus disclosure on HIV exposure risks. Methods During 2013 and 2014, 4901 participants were recruited for the bio-behavioural Sialon-II study in 13 European cities. Behavioural data were collected with a self-administered paper questionnaire. Biological specimens were tested for HIV antibodies. Factors associated with HIV serostatus disclosure with the most recent AI partner were examined using bivariate and multilevel multivariate logistic regression analysis. We also describe the role of serostatus disclosure for HIV exposure of the most recent AI partner. Results Thirty-five percent (n = 1450) of the study participants reported mutual serostatus disclosure with their most recent AI partner or disclosed having HIV to their partner. Most of these disclosures occurred between steady partners (74%, n = 1077). In addition to the type of partner and HIV diagnosis status, other factors positively associated with HIV serostatus disclosure in the multilevel multivariate logistic regression model were recent testing, no condom use, and outness regarding sexual orientation. Disclosure rates were lowest in three south-eastern European cities. Following condom use (51%, n = 2099), HIV serostatus disclosure (20%, n = 807) was the second most common prevention approach with the most recent AI partner, usually resulting in serosorting. A potential HIV exposure risk for the partner was reported by 26% (111/432) of HIV antibody positive study participants. In 18% (20/111) of exposure episodes, an incorrect HIV serostatus was unknowingly communicated. Partner exposures were equally distributed between steady and non-steady partners. Conclusions The probability of HIV exposure through condomless AI is substantially lower after serostatus disclosure compared to non-disclosure. Incorrect knowledge of one’s HIV status contributes to a large proportion of HIV exposures amongst European MSM. Maintaining or improving condom use for anal intercourse with non-steady partners, frequent testing to update HIV serostatus awareness, and increased serostatus disclosure particularly between steady partners are confirmed as key aspects for reducing HIV exposures amongst European MSM.

Abstract
Auditory hallucinations (AH) are a common and distressing experience and patients report distress reduction to be a priority. Relating Therapy adopts a symptom-specific and mechanism focused approach to the reduction of AH distress. We conducted this single-blind, pragmatic, parallel groups, superiority pilot RCT within a single mental health centre in the UK. Patients (18+years) with persistent and distressing AH, irrespective of diagnosis were randomly allocated to receive either Relating Therapy and Treatment-as-usual (RT) or Treatment as-usual alone (TAU). Assessment of outcome was completed pre-randomisation (T0), 16weeks post-randomisation (T1) and 36weeks post-randomisation (T2). The primary outcome was the 5-item Distress scale of the Psychotic Symptoms Rating Scale - Auditory Hallucinations (PSYRATS-AHRS) at T1. We randomly assigned 29 patients to receive RT (n=14) or TAU (n=15). Twenty-five patients (86%) provided complete datasets. Compared with TAU, RT led to reductions in AH distress in the large effect size range across T1 and T2. Our findings suggest that Relating Therapy might be effective for reducing AH distress. A larger, suitably powered phase 3 study is needed to provide a precise estimate of the effects of Relating Therapy for AH distress.

Early intervention for stigma towards mental illness? Promoting positive attitudes towards severe mental illness in primary school children. JOURNAL OF PUBLIC MENTAL HEALTH 2016.

Abstract
Purpose
Stigma towards severe mental illness (SMI) is widespread, exacerbating mental health problems, and impacting on help-seeking and social inclusion. Anti-stigma campaigns are meeting with success, but results are mixed. Earlier intervention to promote positive mental health literacy rather than challenge stigma, may show promise, but little is known about stigma development or interventions in younger children. The purpose of this paper is to investigate children’s knowledge, attitudes and behaviour towards SMI and whether we can positively influence children’s attitudes before stigma develops.
Design/methodology/approach
A cross-sectional study investigated mental health schema in 7-11 year olds. An experimental intervention investigated whether an indirect contact story-based intervention in 7-8 year olds led to more positive mental health schema.
Findings
Young children’s schema were initially positive, and influenced by knowledge and contact with mental illness and intergroup anxiety, but were more stigmatising in older girls as intergroup anxiety increased. The indirect contact intervention was effective in promoting positive mental health schema, partially mediated by knowledge.
Social implications
Intervening early to shape concepts of mental illness more positively, as they develop in young children, may represent a more effective strategy than attempting to challenge and change mental health stigma once it has formed in adolescents and adults.
Originality/value
This study is the first to investigate an intervention targeted at the prevention of stigma towards SMI, in young children, at the point that stigma is emerging.

Abstract
Group Person-Based Cognitive Therapy (PBCT) integrates cognitive therapy and mindfulness to target distinct sources of distress in psychosis. The present study presents data from the first randomised controlled trial investigating group PBCT in people distressed by hearing voices. One-hundred and eight participants were randomised to receive either group PBCT and Treatment As Usual (TAU) or TAU only. While there was no significant effect on the primary outcome, a measure of general psychological distress, results showed significant between-group post-intervention benefits in voice-related distress, perceived controllability of voices and recovery. Participants in the PBCT group reported significantly lower post-treatment levels of depression, with this effect maintained at six-month follow-up. Findings suggest PBCT delivered over 12weeks effectively impacts key dimensions of the voice hearing experience, supports meaningful behaviour change, and has lasting effects on mood.

Abstract
Background Cognitive behavior therapy for psychosis (CBTp) is an effective intervention for people who hear distressing voices (auditory hallucinations). However, there continues to be a problem of poor access to CBTp. Constraints on health care funding require this problem to be addressed without a substantial increase in funding. One solution is to develop guided self-help forms of CBTp to improve access, and a symptom-specific focus on, for example, distressing voices (auditory verbal hallucinations) has the potential to enhance effectiveness. We term this cognitive behavior therapy for distressing voices (CBTv). Methods/design This trial is an external pilot randomized controlled trial comparing the effects of 12-week guided self-help CBTv (with eight therapist support sessions) with a wait list control condition. Informed consent will be obtained from each participant. Half of the 30 participants will be randomized to receive guided self-help CBTv immediately; the remaining half will receive the intervention after a 12-week delay. All participants will continue with their usual treatment throughout the study. Outcomes will be assessed using questionnaires completed at baseline and 12 weeks postrandomization. Interviews will be offered to all those who receive therapy immediately to explore their experiences with the intervention. Discussion The outcomes of this trial, both quantitative and qualitative, will inform the design of a definitive randomized controlled trial of guided self-help CBTv. If this intervention is effective, it could help to increase access to CBT for those who hear distressing voices. Trial registration ISRCTN registration number ISRCTN77762753.

Abstract
Chronic wounds represent a significant burden to health services and are associated with patient morbidity. Novel methods to diagnose and/or treat problematic wounds are needed. Interleukin (IL)-15 is a cytokine involved in a number of biological processes and disease states such as inflammation, healing and cancer progression. The current study explores the expression profile of IL-15 and IL-15 receptor α (IL-15Rα) in chronic wounds and its impact on keratinocytes. IL-15 and IL-15Rα expression were examined in healing and non-healing chronic wounds using qPCR and immunohistochemical analysis. The impact of recombinant IL-15 (rhIL-15) on human adult low calcium temperature (HaCaT) keratinocyte growth and migratory potential was further examined. IL-15 transcript expression was slightly, though non-significantly elevated in healing chronic wounds compared with non-healing chronic wounds. IL-15 protein staining was minimal in both subtypes of chronic wounds. By contrast, IL-15Rα transcript and protein expression were both observed to be enhanced in non-healing chronic wounds compared with healing chronic wounds. The treatment of HaCaT cells with rhIL-15 generally enhanced cell growth and promoted migration. Analysis with small molecule inhibitors suggested that the pro-migratory effect of rhIL-15 may be associated with ERK, AKT, PLCγ and FAK signalling. IL-15 may promote healing traits in keratinocytes and the differential expression of IL-15Rα is observed in chronic wounds. Together, this may imply a complex role for this interleukin in wound healing.

Abstract
BACKGROUND It is important to evaluate change in order to re-assure commissioners, staff and patients of the effectiveness of interventions, but also in order to identify areas for improvement. OBJECTIVE To consider whether analysis of improvement at the level of the individual, taking into account measurement error, may offer a further valuable way to assess change and inform service development over considering change at the group level in a post-acute neuro-rehabilitation unit. METHOD Pre and post intervention Scores on the FIM+FAM Full Scale and Cognitive and Motor subscales were considered for eighteen patients aged between 35 and 81 with mixed diagnoses who attended a post-acute inpatient neuro-rehabilitation unit for treatment. RESULTS Statistically significant improvements were achieved on the FIM+FAM Full Scale and Cognitive and Motor subscales in a whole group analysis. Reliable change analyses for each patient within each subscale however identified only half of the sample achieved reliable improvement within the Motor domain and just one person within the Cognitive domain (5.6%). CONCLUSIONS Findings are consistent with the emphasis of the rehabilitation unit on physical/motor function, and unsurprising as many of those assessed had multiple sclerosis, an often deteriorative condition. Use of reliable change analysis allowed a more detailed understanding of intervention impact, potentially identifying what services reliably work for whom, thereby informing future planning.
