The delivery of creative socially prescribed activities for people with serious mental health needs during lockdown: Learning about remote, digital and hybrid delivery.

BACKGROUND: Social prescribing interventions connect mental health service users to community resources, to support physical and mental wellbeing and promote recovery. COVID-19 restrictions impacted the delivery of socially prescribed activities, preventing face to face contact for long periods. AIMS: The aim of this study was to understand how Voluntary Community and Social Enterprise (VCSE) organisations working with a local NHS mental health Trust responded to the challenges of social distancing during the COVID-19 pandemic. This understanding will be used to make recommendations for future practice, post-lockdown. METHODS: Using a convergent mixed methods design, we surveyed VCSE providers of socially prescribed activities intended to be accessible and appropriate for people with severe mental health needs. Follow-up interviews explored further how they adapted during the first year of the pandemic, the challenges they faced, and how they sought to overcome them. The survey and interview data were analysed separately and then compared to identify convergent and divergent findings. RESULTS: Twenty VCSE representatives completed the survey which provided a snapshot of changes in levels of connection and numbers reached during lockdown. Of 20 survey respondents, 11 participated in follow-up interviews. Interviews revealed that lockdown necessitated rapid change and responsive adaptation; activities were limited by resource, funding, safeguarding and government restrictions; no single format suited all group members; connection was key; and impact was difficult to gauge. CONCLUSIONS: VCSE organisations commissioned to deliver creative socially prescribed activities during the pandemic rapidly adapted their offer to comply with government restrictions. Responsive changes were made, and new knowledge and skills were gained. Drawing on experiences during lockdown, VCSE organisations should develop bespoke knowledge, skills and practices to engage service users in future hybrid delivery of arts, sports, cultural and creative community activities, and to ensure that digital activities offer an equivalent degree of connection to face-to-face ones. Additionally, more effective methods of gaining feedback about patient experience of hybrid delivery is needed.

Clinical, experimental and pathophysiological effects of Yaq-001: a non-absorbable, gut-restricted adsorbent in models and patients with cirrhosis.

OBJECTIVE: Targeting bacterial translocation in cirrhosis is limited to antibiotics with risk of antimicrobial resistance. This study explored the therapeutic potential of a non-absorbable, gut-restricted, engineered carbon bead adsorbent, Yaq-001 in models of cirrhosis and acute-on-chronic liver failure (ACLF) and, its safety and tolerability in a clinical trial in cirrhosis. DESIGN: Performance of Yaq-001 was evaluated in vitro. Two-rat models of cirrhosis and ACLF, (4 weeks, bile duct ligation with or without lipopolysaccharide), receiving Yaq-001 for 2 weeks; and two-mouse models of cirrhosis (6-week and 12-week carbon tetrachloride (CCl4)) receiving Yaq-001 for 6 weeks were studied. Organ and immune function, gut permeability, transcriptomics, microbiome composition and metabolomics were analysed. The effect of faecal water on gut permeability from animal models was evaluated on intestinal organoids. A multicentre, double-blind, randomised, placebo-controlled clinical trial in 28 patients with cirrhosis, administered 4 gr/day Yaq-001 for 3 months was performed. RESULTS: Yaq-001 exhibited rapid adsorption kinetics for endotoxin. In vivo, Yaq-001 reduced liver injury, progression of fibrosis, portal hypertension, renal dysfunction and mortality of ACLF animals significantly. Significant impact on severity of endotoxaemia, hyperammonaemia, liver cell death, systemic inflammation and organ transcriptomics with variable modulation of inflammation, cell death and senescence in the liver, kidneys, brain and colon was observed. Yaq-001 reduced gut permeability in the organoids and impacted positively on the microbiome composition and metabolism. Yaq-001 regulated as a device met its primary endpoint of safety and tolerability in the clinical trial. CONCLUSIONS: This study provides strong preclinical rationale and safety in patients with cirrhosis to allow clinical translation. TRIAL REGISTRATION NUMBER: NCT03202498.

Modulation of the Gut Microbiota to Control Antimicrobial Resistance (AMR)-A Narrative Review with a Focus on Faecal Microbiota Transplantation (FMT).

Antimicrobial resistance (AMR) is one of the greatest challenges facing humanity, causing a substantial burden to the global healthcare system. AMR in Gram-negative organisms is particularly concerning due to a dramatic rise in infections caused by extended-spectrum beta-lactamase and carbapenemase-producing Enterobacterales (ESBL and CPE). These pathogens have limited treatment options and are associated with poor clinical outcomes, including high mortality rates. The microbiota of the gastrointestinal tract acts as a major reservoir of antibiotic resistance genes (the resistome), and the environment facilitates intra and inter-species transfer of mobile genetic elements carrying these resistance genes. As colonisation often precedes infection, strategies to manipulate the resistome to limit endogenous infections with AMR organisms, as well as prevent transmission to others, is a worthwhile pursuit. This narrative review presents existing evidence on how manipulation of the gut microbiota can be exploited to therapeutically restore colonisation resistance using a number of methods, including diet, probiotics, bacteriophages and faecal microbiota transplantation (FMT).

So You Want to Build Your Disease's First Online Patient Registry: An Educational Guide for Patient Organizations Based on US and European Experience.

Patient registries fulfill a number of key roles for clinicians, researchers, non-profit organizations, payers, and policy makers. They can help the field understand the natural history of a condition, determine the effectiveness of interventions, measure safety, and audit the quality of care provided. Successful registries in cystic fibrosis, Duchenne's muscular dystrophy, and other rare diseases have become a model for accelerating progress. However, the complex tasks required to develop a modern registry can seem overwhelming, particularly for those who are not from a technical background. In this Education article, a team of co-authors from across patient advocacy, technology, privacy, and commercial perspectives who have worked on a number of such projects offer a "Registry 101" primer to help get started. We will outline the promise and potential of patient registries with worked case examples, identify some of the key technical considerations you will need to consider, describe the type of data you might want to collect, consider privacy risks to protect your users, sketch out some of the paths towards long-term financial sustainability we have observed, and conclude with plans to mitigate some of the challenges that can occur and signpost interested readers to further resources. While rapid growth in the digital health market has presented numerous opportunities to those at the beginning of their journey, it is important to start with the long-term goals in mind and to benefit from the learnings of those who have walked this path before.

Exaggerated inflammatory response to bacterial products in decompensated cirrhotic patients is orchestrated by interferons IL-6 and IL-8.

Cirrhosis-associated immune dysfunction (CAID) contributes to disease progression and organ failure development. We interrogated immune system function in nonseptic compensated and decompensated cirrhotic patients using the TruCulture whole blood stimulation system, a novel technique that allows a more accurate representation than traditional methods, such as peripheral blood mononuclear cell culture, of the immune response in vivo. Thirty cirrhotics (21 decompensated and 9 compensated) and seven healthy controls (HCs) were recruited. Whole blood was drawn directly into three TruCulture tubes [unstimulated to preloaded with heat-killed Escherichia coli 0111:B4 (HKEB) or lipopolysaccharide (LPS)] and incubated in dry heat blocks at 37°C for 24 h. Cytokine analysis of the supernatant was performed by multiplex assay. Cirrhotic patients exhibited a robust proinflammatory response to HKEB compared with HCs, with increased production of interferon-γ-induced protein 10 (IP-10) and IFN-λ1, and to LPS, with increased production of IFN-λ1. Decompensated patients demonstrated an augmented immune response compared with compensated patients, orchestrated by an increase in type I, II, and III interferons, and higher levels of IL-1ß, IL-6, and IL-8 post-LPS stimulation. IL-1ß, TNF-α, and IP-10 post-HKEB stimulation and IP-10 post-LPS stimulation negatively correlated with biochemical markers of liver disease severity and liver disease severity scores. Cirrhotic patients exposed to bacterial products exhibit an exaggerated inflammatory response orchestrated by IFNs, IL-6, and IL-8. Poststimulation levels of a number of proinflammatory cytokines negatively correlate with markers of liver disease severity raising the possibility that the switch to an immunodeficient phenotype in CAID may commence earlier in the course of advanced liver disease. NEW & NOTEWORTHY Decompensated cirrhotic patients, compared with compensated patients, exhibit a greater exaggerated inflammatory response to bacterial products orchestrated by interferons, IL-6, and IL-8. Postbacterial product stimulation levels of a number of pro-inflammatory cytokines negatively correlate with liver disease severity biomarkers and liver disease severity scores raising the possibility that the switch to an immunodeficient phenotype in cirrhosis-associated immune dysfunction may commence earlier in the course of advanced liver disease.

Rifaximin-α reduces gut-derived inflammation and mucin degradation in cirrhosis and encephalopathy: RIFSYS randomised controlled trial.

BACKGROUND & AIMS: Rifaximin-α is efficacious for the prevention of recurrent hepatic encephalopathy (HE), but its mechanism of action remains unclear. We postulated that rifaximin-α reduces gut microbiota-derived endotoxemia and systemic inflammation, a known driver of HE. METHODS: In a placebo-controlled, double-blind, mechanistic study, 38 patients with cirrhosis and HE were randomised 1:1 to receive either rifaximin-α (550 mg BID) or placebo for 90 days. PRIMARY OUTCOME: 50% reduction in neutrophil oxidative burst (OB) at 30 days. SECONDARY OUTCOMES: changes in psychometric hepatic encephalopathy score (PHES) and neurocognitive functioning, shotgun metagenomic sequencing of saliva and faeces, plasma and faecal metabolic profiling, whole blood bacterial DNA quantification, neutrophil toll-like receptor (TLR)-2/4/9 expression and plasma/faecal cytokine analysis. RESULTS: Patients were well-matched: median MELD (11 rifaximin-α vs. 10 placebo). Rifaximin-α did not lead to a 50% reduction in spontaneous neutrophil OB at 30 days compared to baseline (p = 0.48). However, HE grade normalised (p = 0.014) and PHES improved (p = 0.009) after 30 days on rifaximin-α. Rifaximin-α reduced circulating neutrophil TLR-4 expression on day 30 (p = 0.021) and plasma tumour necrosis factor-α (TNF-α) (p <0.001). Rifaximin-α suppressed oralisation of the gut, reducing levels of mucin-degrading sialidase-rich species, Streptococcus spp, Veillonella atypica and parvula, Akkermansia and Hungatella. Rifaximin-α promoted a TNF-α- and interleukin-17E-enriched intestinal microenvironment, augmenting antibacterial responses to invading pathobionts and promoting gut barrier repair. Those on rifaximin-α were less likely to develop infection (odds ratio 0.21; 95% CI 0.05-0.96). CONCLUSION: Rifaximin-α led to resolution of overt and covert HE, reduced the likelihood of infection, reduced oralisation of the gut and attenuated systemic inflammation. Rifaximin-α plays a role in gut barrier repair, which could be the mechanism by which it ameliorates bacterial translocation and systemic endotoxemia in cirrhosis. CLINICAL TRIAL NUMBER: ClinicalTrials.gov NCT02019784. LAY SUMMARY: In this clinical trial, we examined the underlying mechanism of action of an antibiotic called rifaximin-α which has been shown to be an effective treatment for a complication of chronic liver disease which effects the brain (termed encephalopathy). We show that rifaximin-α suppresses gut bacteria that translocate from the mouth to the intestine and cause the intestinal wall to become leaky by breaking down the protective mucus barrier. This suppression resolves encephalopathy and reduces inflammation in the blood, preventing the development of infection.

Understanding young adults' reasons for seeking 'clinically unnecessary' urgent and emergency care: A qualitative interview study.

BACKGROUND: Studies have identified young adults as more likely to use emergency departments for 'clinically unnecessary' problems, with limited similar evidence for emergency ambulance use. Media portrayals depict young adults as motivated by 'convenience', but little research has explored the reasons for their help-seeking behaviour. METHODS: Qualitative interviews with 16 young adults (18-30) considered by clinicians to have made unnecessary use of emergency ambulance, emergency department or an urgent GP appointment. Data analysis was informed by interpretive phenomenological analysis. FINDINGS: A number of interrelated factors contributed to participants' decisions. They were anxious about the seriousness of their symptoms, sometimes exacerbated by reduced coping capacity due to poor mental health or life stresses. They looked to others to facilitate their decision making, who sometimes encouraged urgent contact. They wanted to avoid impact on existing day-to-day commitments including work or study. They had strong views about different health services, sometimes based on frustration with lack of resolution of on-going health problems. Convenience was not identified as a significant factor, although some actions could be interpreted in this light if the context was not considered. CONCLUSIONS: Young adults make 'clinically unnecessary' use of urgent and emergency care for more than convenience. Their decisions need to be understood in relation to the complexity of their experience, including lack of confidence in making health-related decisions, lowered coping capacity and concern to maintain normal daily life.

Person-centred experiential therapy versus cognitive behavioural therapy delivered in the English Improving Access to Psychological Therapies service for the treatment of moderate or severe depression (PRaCTICED): a pragmatic, randomised, non-inferiority trial.

BACKGROUND: The UK Government's implementation in 2008 of the Improving Access to Psychological Therapies (IAPT) initiative in England has hugely increased the availability of cognitive behavioural therapy (CBT) for the treatment of depression and anxiety in primary care. Counselling for depression-a form of person-centred experiential therapy (PCET)-has since been included as an IAPT-approved therapy, but there is no evidence of its efficacy from randomised controlled trials (RCTs), as required for recommendations by the National Institute for Health and Care Excellence. Therefore, we aimed to examine whether PCET is cost effective and non-inferior to CBT in the treatment of moderate and severe depression within the IAPT service. METHODS: This pragmatic, randomised, non-inferiority trial was done in the Sheffield IAPT service in England and recruited participants aged 18 years or older with moderate or severe depression on the Clinical Interview Schedule-Revised. We excluded participants presenting with an organic condition, a previous diagnosis of personality disorder, bipolar disorder, or schizophrenia, drug or alcohol dependency, an elevated clinical risk of suicide, or a long-term physical condition. Eligible participants were randomly assigned (1:1), independently of the research team, and stratified by site with permuted block sizes of two, four, or six, to receive either PCET or CBT by use of a remote, web-based system that revealed therapy after patient details were entered. Those assessing outcomes were masked to treatment allocation. Participants were seen by appropriately trained PCET counsellors and CBT therapists in accordance with the IAPT service delivery model. Depression severity and symptomatology measured by the Patient Health Questionnaire-9 (PHQ-9) at 6 months post-randomisation was the primary outcome, with the PHQ-9 score at 12 months post-randomisation being a key secondary outcome. These outcomes were analysed in the modified intention-to-treat population, which comprised all randomly assigned patients with complete data, and the per-protocol population, which comprised all participants who did not switch from their randomised treatment and received between four and 20 sessions. Safety was analysed in all randomly assigned patients. The non-inferiority margin was set a priori at 2 PHQ-9 points. Patient safety was monitored throughout the course of therapy, adhering to service risk procedures for monitoring serious adverse events. This trial is registered at the ISRCTN Registry, ISRCTN06461651, and is complete. FINDINGS: From Nov 11, 2014, to Aug 3, 2018, 9898 patients were referred to step three treatments in the Sheffield IAPT service for common mental health problems, of whom 761 (7·7%) were referred to the trial. Of these, we recruited and randomly assigned 510 participants to receive either PCET (n=254) or CBT (n=256). In the PCET group, 138 (54%) participants were female and 116 (46%) were male, and 225 (89%) were White, 16 (6%) were non-White, and 13 (5%) had missing ethnicity data. In the CBT group, 155 (61%) participants were female and 101 (39%) were male, and 226 (88%) were White, 17 (7%) were non-White, and 13 (5%) had missing ethnicity data. The 6-month modified intention-to-treat analysis comprised 401 (79%) of the enrolled participants (201 in the PCET group; 200 in the CBT group) and the 12-month modified intention-to-treat analysis comprised 319 participants (167 in the PCET group; 152 in the CBT group). The 6-month per-protocol analysis comprised 298 participants (154 in the PCET group; 144 in the CBT group). At 6 months post-randomisation, PCET was non-inferior to CBT in the intention-to-treat population (mean PHQ-9 score 12·74 [SD 6·54] in the PCET group and 13·25 [6·35] in the CBT group; adjusted mean difference -0·35 [95% CI -1·53 to 0·84]) and in the per-protocol population (12·73 [SD 6·57] in the PCET group and 12·71 [6·33] in the CBT group; 0·27 [95% CI -1·08 to 1·62]). At 12 months post-randomisation, there was a significant adjusted between-group difference in mean PHQ-9 score in favour of CBT (1·73 [95% CI 0·26-3·19]), with a 95% CI exceeding the 2-point non-inferiority margin. There were two deaths, one death by suicide in the PCET group and one due to chronic obstructive pulmonary disease in the CBT group. Both were assessed by the responsible clinician to be unrelated to the trial. In terms of using emergency departments for depression-related events, four people (three in the PCET group; one in the CBT group) made more than a single use and six people (three in the PCET group; three in the CBT group) made a single use. One patient in the PCET group had inpatient treatment for a depression-related event. INTERPRETATION: This trial is the first to examine the two most frequently administered psychological therapies in the IAPT service. The finding of non-inferiority of PCET to CBT at 6 months supports the results from large, routine, non-randomised datasets from the IAPT programme. Given the high demand for psychological therapies and the need for patient choice, our findings suggest the need for continued investment in the training and delivery of PCET for improving short-term outcomes, but suggest that PCET might be inferior to CBT at 12 months.

Targeting the gut-liver-immune axis to treat cirrhosis.

Cirrhotic portal hypertension is characterised by development of the decompensating events of ascites, encephalopathy, portal hypertensive bleeding and hepatorenal syndrome, which arise in a setting of cirrhosis-associated immune dysfunction (CAID) and define morbidity and prognosis. CAID describes the dichotomous observations that systemic immune cells are primed and display an inflammatory phenotype, while failing to mount robust responses to pathogen challenge. Bacterial infections including spontaneous bacterial peritonitis are common complications of advanced chronic liver disease and can precipitate variceal haemorrhage, hepatorenal syndrome and acute-on-chronic liver failure; they frequently arise from gut-derived organisms and are closely linked with dysbiosis of the commensal intestinal microbiota in advanced chronic liver disease.Here, we review the links between cirrhotic dysbiosis, intestinal barrier dysfunction and deficits of host-microbiome compartmentalisation and mucosal immune homoeostasis that occur in settings of advanced chronic liver disease. We discuss established and emerging therapeutic strategies targeted at restoring intestinal eubiosis, augmenting gut barrier function and ameliorating the mucosal and systemic immune deficits that characterise and define the course of decompensated cirrhosis.

Ototoxicity-induced hearing loss and quality of life in survivors of paediatric cancer.

INTRODUCTION: Hearing loss is a permanent and debilitating side-effect of a range of interventions commonly used in the treatment of childhood cancers, primarily ototoxic medications such as cisplatin. The purpose of this study was to examine the impact of hearing loss, in a population already at risk of reduced quality of life due to the cancer and treatment-related factors. METHODS: This study used a questionnaire specifically designed to tap issues relevant to children with hearing loss, the Paediatric Audiology Quality of Life questionnaire (PAQL). Parents of 78 children treated for a wide range of solid tumours and leukaemias completed the PAQL, 41 of whom had sensorineural hearing loss as a result of the cancer treatment. RESULTS: Significant differences between those children with hearing loss and those whose hearing remained normal were found on all four scales of the questionnaire. Children affected by ototoxicity were rated as having poorer quality of life in terms of their ability to communicate with family and peers, their independence, interactions with peers and emotional well-being. CONCLUSION: These results highlight the impact of acquired hearing loss and reinforce the importance of assessing quality of life with a measure capable of tapping the issues of consequence to the population under investigation. They also have implications for the clinical management of children during and following treatment for a wide range of cancers: medically, audiologically, psychologically and educationally.

Faecal cytokine profiling as a marker of intestinal inflammation in acutely decompensated cirrhosis.

BACKGROUND & AIMS: Gut dysbiosis and inflammation perpetuate loss of gut barrier integrity (GBI) and pathological bacterial translocation (BT) in cirrhosis, contributing to infection risk. Little is known about gut inflammation in cirrhosis and how this differs in acute decompensation (AD). We developed a novel approach to characterise intestinal immunopathology by quantifying faecal cytokines (FCs) and GBI markers. METHODS: Faeces and plasma were obtained from patients with stable cirrhosis (SC; n = 16), AD (n = 47), and healthy controls (HCs; n = 31). A panel of 15 cytokines and GBI markers, including intestinal fatty-acid-binding protein-2 (FABP2), d-lactate, and faecal calprotectin (FCAL), were quantified by electrochemiluminescence/ELISA. Correlations between analytes and clinical metadata with univariate and multivariate analyses were performed. RESULTS: Faecal (F) IL-1ß, interferon gamma, tumour necrosis factor alpha, IL-21, IL-17A/F, and IL-22 were significantly elevated in AD vs. SC (q <0.01). F-IL-23 was significantly elevated in AD vs. HC (p = 0.0007). FABP2/d-lactate were significantly increased in faeces in AD vs. SC and AD vs. HC (p <0.0001) and in plasma (p = 0.0004; p = 0.011). F-FABP2 correlated most strongly with disease severity (Spearman's rho: Child-Pugh 0.466; p <0.0001; model for end-stage liver disease 0.488; p <0.0001). FCAL correlated with plasma IL-21, IL-1ß, and IL-17F only and none of the faecal analytes. F-cytokines and F-GBI markers were more accurate than plasma in discriminating AD from SC. CONCLUSIONS: FC profiling represents an innovative approach to investigating the localised intestinal cytokine micro-environment in cirrhosis. These data reveal that AD is associated with a highly inflamed and permeable gut barrier. FC profiles are very different from the classical innate-like features of systemic inflammation. There is non-specific upregulation of TH1/TH17 effector cytokines and those known to mediate intestinal barrier damage. This prevents mucosal healing in AD and further propagates BT and systemic inflammation. LAY SUMMARY: The gut barrier is crucial in cirrhosis in preventing infection-causing bacteria that normally live in the gut from accessing the liver and other organs via the bloodstream. Herein, we characterised gut inflammation by measuring different markers in stool samples from patients at different stages of cirrhosis and comparing this to healthy people. These markers, when compared with equivalent markers usually measured in blood, were found to be very different in pattern and absolute levels, suggesting that there is significant gut inflammation in cirrhosis related to different immune system pathways to that seen outside of the gut. This provides new insights into gut-specific immune disturbances that predispose to complications of cirrhosis, and emphasises that a better understanding of the gut-liver axis is necessary to develop better targeted therapies.

A novel in vivo model using immunotoxin in the absence of p-glycoprotein to achieve ultra selective depletion of target cells: Applications in trogocytosis and beyond.

A commonly employed method to determine the function of a particular cell population and to assess its contribution to the overall system in vivo is to selectively deplete that population and observe the effects. Using monoclonal antibodies to deliver toxins to target cells can achieve this with a high degree of efficiency. Here, we describe an in vivo model combining the use of immunotoxins and multidrug resistant (MDR) gene deficient mice so that only MDR deficient cells expressing the target molecule would be depleted while target molecule expressing, but MDR sufficient, cells are spared. This allows targeted depletion at a higher degree of specificity than has been previously achieved. We have applied this technique to study trogocytosis, the intercellular transfer of cell surface molecules, but this principle could also be adapted using technology already available for use in other fields of study.

Variation in the delivery of telephone advice by emergency medical services: a qualitative study in three services.

BACKGROUND: An emergency ambulance is not always the appropriate response for emergency medical service patients. Telephone advice aims to resolve low acuity calls over the phone, without sending an ambulance. In England, variation in rates of telephone advice and patient recontact between services raises concerns about inequities in care. To understand this variation, this study aimed to explore operational factors influencing the provision of telephone advice. METHODS: This is a multimethod qualitative study in three emergency medical services in England with different rates of telephone advice and recontact. Non-participant observation (120 hours) involved 20 call handlers and 27 clinicians (eg, paramedics). Interviews were conducted with call handlers, clinicians and clinician managers (n=20). RESULTS: Services varied in their views of the role of telephone advice, selection of their workforce, tasks clinicians were expected and permitted to do, and access to non-ambulance responses. Telephone advice was viewed either as an acceptable approach to managing demand or a way of managing risk. The workforce could be selected for their expertise or their inability to work 'on-the-road'. Some services permitted proactive identification of calls for a lower priority response and provided access to a wider range of response options. The findings aligned with telephone advice rates for each service, particularly explaining why one service had lower rates. CONCLUSION: Some of the variation observed can be explained by operational differences between services and some of it by access to alternative response options in the wider urgent and emergency care system. The findings indicate scope for greater consistency in the delivery of telephone advice to ensure the widest range of options to meet the needs of different populations, regardless of geographical location.

Understanding Theory of Mind in Deaf and Hearing College Students.

Theory of Mind-the understanding that people have thoughts, wants, and beliefs that influence their interpersonal behavior-is an aspect of social cognition that develops with consistent, increasing complexity across age groups, languages, and cultures. Observed delays in theory of mind development among deaf children and others has led to a conversational account of theory of mind development and its delays in terms of the nature and amount of social communication experienced by children directly (conversationally) and indirectly (via overhearing). The present study explored theory of mind in deaf young adults by evaluating their understanding of sarcasm and advanced false belief (second-order false belief and double bluff), as well as related cognitive abilities. Consistent with previous studies, deaf participants scored significantly below hearing peers on all three theory of mind tasks. Performance was unrelated to their having had early access to social communication via either sign language (from deaf parents) or spoken language (through cochlear implants), suggesting that deaf participants' performance was not solely a function of access to social communication in early childhood. The finding of different predictors of theory of mind performance for deaf and hearing groups is discussed in terms of its language, social, and cognitive foundations.

Risk factors for negative experiences during psychotherapy.

BACKGROUND: It is estimated that between 3% and 15% of patients have a negative experience of psychotherapy, but little is understood about this. AIMS: The aim of this study was to investigate the factors associated with patients' negative therapy experiences. METHOD: The data comprised 185 patient and 304 therapist questionnaires, 20 patient and 20 therapist interviews. Patients reported on an unhelpful or harmful experience of therapy, and therapists on a therapy where they thought the patient they were working with had a poor or harmful experience. These were transcribed and analysed using thematic analysis. RESULTS: There was a Lack of fit between Patient needs, Therapist skills, and Service structures. This could result in Fault Lines, a tension between Safety and containment and Power and control. This tension led to Strain and Poor Engagement, which led to Consequences following the negative therapy experience. CONCLUSIONS: Patients require clear information, choice, involvement in decision-making, explicit contracting and clarity about sessions and progress. Opportunities for patient feedback should be the norm, where the therapist and service are vigilant for signs of deterioration and solutions considered. Clinical and methodological significance of this article: Estimates of "unwanted effects," including long-lasting effects, of psychotherapy have ranged from 3% to 15%. Few empirical studies have been conducted in this area. This study aimed to address this gap and provide clinicians with a model of risk factors for negative therapy effects. The findings of this study indicate the importance of providing patients with a supportive service structure that offers clear information, choice and involvement in decision-making. Explicit contracting at the beginning of therapy and clarity about sessions and progress are also important in managing patient expectations throughout. Opportunities for patient feedback should be provided.

Treatment of caffeine toxicity with metoprolol.

A 27-year-old man presented with an intentional overdose of concentrated caffeine powder that he bought over the internet. The patient received benzodiazepines and ondansetron for symptomatic treatment when he arrived in the Emergency Department (ED). Subsequently, he developed recurrent supraventricular tachycardia in the ED. The SVT was successfully treated with metoprolol. The patient's caffeine level was >90 mg/L. This is the first known report of treatment of caffeine-induced supraventricular tachycardia with metoprolol.

Exploring variation in how ambulance services address non-conveyance: a qualitative interview study.

OBJECTIVES: There is considerable variation in non-conveyance rates between ambulance services in England. The aim was to explore variation in how each ambulance service addressed non-conveyance for calls ending in telephone advice and discharge at scene. DESIGN: A qualitative interview study. SETTING: Ten large regional ambulance services covering 99% of the population in England. PARTICIPANTS: Between four and seven interviewees from each ambulance service including managers, paramedics and healthcare commissioners, totalling 49 interviews. METHODS: Telephone semistructured interviews. RESULTS: The way interviewees in each ambulance service discussed non-conveyance within their organisation varied for three broad themes. First, ambulance service senior management appeared to set the culture around non-conveyance within an organisation, viewing it either as an opportunity or as a risky endeavour. Although motivation levels to undertake non-conveyance did not appear to be directly affected by the stability of an ambulance service in terms of continuity of leadership and externally assessed quality, this stability could affect the ability of the organisation to innovate to increase non-conveyance rates. Second, descriptions of workforce configuration differed between ambulance services, as well as how this workforce was used, trained and valued. Third, interviewees in each ambulance service described health and social care in the wider emergency and urgent care system differently in terms of availability of services that could facilitate non-conveyance, the amount of collaborative working between health and social care services and the ambulance service and complexity related to the numbers of services and healthcare commissioners with whom they had to work. CONCLUSIONS: This study suggests that factors within and outside the control of ambulance services may contribute to variation in non-conveyance rates. These findings can be tested in a quantitative analysis of factors affecting variation in non-conveyance rates between ambulance services in England.

Therapeutic plasma exchange as a novel treatment for severe intrahepatic cholestasis of pregnancy: Case series and mechanism of action.

INTRODUCTION: Intrahepatic cholestasis of pregnancy is characterised by pruritus and elevated serum bile acids. The pruritus can be severe, and pharmacological options achieve inconsistent symptomatic improvement. Raised bile acids are linearly associated with adverse fetal outcomes, with existing management of limited benefit. We hypothesised that therapeutic plasma exchange removes pruritogens and lowers total bile acid concentrations, and improves symptoms and biochemical abnormalities in severe cases that have not responded to other treatments. METHODS: Four women with severe pruritus and hypercholanemia were managed with therapeutic plasma exchange. Serial blood biochemistry and visual analogue scores of itch severity were obtained. Blood and waste plasma samples were collected before and after exchange; individual bile acids and sulfated progesterone metabolites were measured with HPLC-MS, autotaxin activity and cytokine profiles with enzymatic methods. Results were analysed using segmental linear regression to describe longitudinal trends, and ratio t tests. RESULTS: Total bile acids and visual analogue itch scores demonstrated trends to transiently improve following plasma exchange, with temporary symptomatic benefit reported. Individual bile acids (excluding the drug ursodeoxycholic acid), and the sulfated metabolites of progesterone reduced following exchange (P = .03 and P = .04, respectively), whilst analysis of waste plasma demonstrated removal of autotaxin and cytokines. CONCLUSIONS: Therapeutic plasma exchange can lower potentially harmful bile acids and improve itch, likely secondary to the demonstrated removal of pruritogens. However, the limited current experience and potential complications, along with minimal sustained symptomatic benefit, restrict its current use to women with the most severe disease for whom other treatment options have been exhausted.

The Relationship between Types of Attention and Auditory Processing Skills: Reconsidering Auditory Processing Disorder Diagnosis.

Measures of attention have been found to correlate with specific auditory processing tests in samples of children suspected of Auditory Processing Disorder (APD), but these relationships have not been adequately investigated. Despite evidence linking auditory attention and deficits/symptoms of APD, measures of attention are not routinely used in APD diagnostic protocols. The aim of the study was to examine the relationship between auditory and visual attention tests and auditory processing tests in children with APD and to assess whether a proposed diagnostic protocol for APD, including measures of attention, could provide useful information for APD management. A pilot study including 27 children, aged 7-11 years, referred for APD assessment was conducted. The validated test of everyday attention for children, with visual and auditory attention tasks, the listening in spatialized noise sentences test, the children's communication checklist questionnaire and tests from a standard APD diagnostic test battery were administered. Pearson's partial correlation analysis examining the relationship between these tests and Cochrane's Q test analysis comparing proportions of diagnosis under each proposed battery were conducted. Divided auditory and divided auditory-visual attention strongly correlated with the dichotic digits test, r = 0.68, p < 0.05, and r = 0.76, p = 0.01, respectively, in a sample of 20 children with APD diagnosis. The standard APD battery identified a larger proportion of participants as having APD, than an attention battery identified as having Attention Deficits (ADs). The proposed APD battery excluding AD cases did not have a significantly different diagnosis proportion than the standard APD battery. Finally, the newly proposed diagnostic battery, identifying an inattentive subtype of APD, identified five children who would have otherwise been considered not having ADs. The findings show that a subgroup of children with APD demonstrates underlying sustained and divided attention deficits. Attention deficits in children with APD appear to be centred around the auditory modality but further examination of types of attention in both modalities is required. Revising diagnostic criteria to incorporate attention tests and the inattentive type of APD in the test battery, provides additional useful data to clinicians to ensure careful interpretation of APD assessments.
