Off-label ketamine treatment has shown acute antidepressant effects that offer hope for patients with therapy-resistant depression. However, its potential for integration into treatment algorithms is controversial, not least because the evidence base for maintenance treatment with repeated ketamine administration is currently weak. Ketamine is also a drug of misuse, which has raised concerns regarding the target population. Little is known about which patients would seek ketamine treatment if it were more widely available.

To explore some of the characteristics of the patients actively seeking ketamine treatment.

An online survey containing questions about duration of current depressive episode, number of antidepressants used and other comments was completed by patients who were exploring the internet regarding the possibility of ketamine for depression.

Of the 1088 people who registered their interest, 93.3% reported depression, 64.3% reported a chronic course of their symptoms and in the past 10 years, 86.3% had tried at least two antidepressants. Desperation was a common theme, but this appeared to be competently expressed. A small minority (<8%) reported experience of illegal ketamine use.

It cannot be ruled out that patients with different degrees of treatment resistance and comorbidities will seek treatment with ketamine. This stresses the urgency to perform larger randomised controlled trials as well as to systematically monitor outcomes and adverse effects of ketamine, that is currently prescribed off-label for patients in need.

Literature has focused on effect sizes rather than individual-level improvement rates to determine how effectively services address burgeoning numbers of adolescents with anxiety and depression.

To consider how many adolescents report reliable improvement in anxiety, depression and comorbid depression and anxiety by end of treatment.

The primary outcome was reliable improvement (i.e. change greater than likely the result of measurement error) in self-reported anxiety and depression for N = 4464 adolescents (mean age 14.5 years, s.d. = 1.9; 75% female; 61% White) seen in specialist mental health services in England.

In total, 53% of those with anxiety, 44% with depression, and 35% with comorbid depression and anxiety showed reliable improvement.

Improvement rates were higher than previously reported, but lower than generally used in advice to the public. There may be a need to set more realistic expectations, including with young people who seek help.

All authors were involved in the programme of service transformation that this report draws on. M.W. led the outcomes and evaluation group that agreed the approach to measurement used in the initiative.

Use of second-generation antipsychotics (SGA) has increased in recent years; however, their use and effect on metabolic outcomes has been poorly characterised in population-level studies.

This study aimed to determine the associations between SGA use and metabolic indicators in a general population.

We used data from the Canadian Health Measures Survey, a cross-sectional survey of Canadian households. Participants were Canadians aged 3–79 years, living in one of the ten provinces. Several metabolic indicators were examined, including weight, body mass index, waist circumference, hypertension, diabetes and two definitions of metabolic syndrome.

The proportion of Canadians taking an SGA tripled over the study period. SGA use was significantly associated with hypertension (odds ratio 1.94, 95% CI 1.07–3.55) and abdominal obesity in adults, as defined by the National Cholesterol Education Program–Adult Treatment Panel III (odds ratio 2.62, 95% CI 1.45–4.71).

Evidence of metabolic dysfunction with SGAs is seen in the Canadian population, along with a rapid increase in prevalence of use since 2007.

A theoretical model of individuals' experiences before, during and after involuntary admission has not yet been established.

To develop an understanding of individuals' experiences over the course of the involuntary admission process.

Fifty individuals were recruited through purposive and theoretical sampling and interviewed 3 months after their involuntary admission. Analyses were conducted using a Straussian grounded theory approach.

The ‘theory of preserving control’ (ToPC) emerged from individuals' accounts of how they adapted to the experience of involuntary admission. The ToPC explains how individuals manage to reclaim control over their emotional, personal and social lives and consists of three categories: ‘losing control’, ‘regaining control’ and ‘maintaining control’, and a number of related subcategories.

Involuntary admission triggers a multifaceted process of control preservation. Clinicians need to develop therapeutic approaches that enable individuals to regain and maintain control over the course of their involuntary admission.

Cognitive–behavioural therapy (CBT) is the treatment of choice for generalised anxiety disorder (GAD), yielding significant improvements in approximately 50% of patients. There is significant room for improvement in the outcomes of treatment, especially in recovery.

We aimed to compare metacognitive therapy (MCT) with the gold standard treatment, CBT, in patients with GAD (clinicaltrials.gov identifier: NCT00426426).

A total of 246 patients with long-term GAD were assessed and 81 were randomised into three conditions: CBT (n = 28), MCT (n = 32) and a wait-list control (n = 21). Assessments were made at pre-treatment, post-treatment and at 2 year follow-up.

Both CBT and MCT were effective treatments, but MCT was more effective (mean difference 9.762, 95% CI 2.679–16.845, P = 0.004) and led to significantly higher recovery rates (65% v. 38%). These differences were maintained at 2 year follow-up.

MCT seems to produce recovery rates that exceed those of CBT. These results demonstrate that the effects of treatment cannot be attributed to non-specific therapy factors.

It is well established that migration and ethnic minority status are risk factors for psychotic disorders. Recent studies have aimed to determine if they are also associated with subclinical psychosis (psychotic-like experiences and schizotypal traits).

We aimed to determine to what extent migrant and ethnic minority groups are associated with higher risk of subclinical psychosis.

We conducted a systematic review, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, and examined findings by ethnicity, migrant status, outcomes of subclinical psychosis and host country. A meta-analysis was carried out with robust variance estimation where possible, to handle statistically dependent effect size estimates.

We included 28 studies (19 studies on psychotic-like experiences and 9 studies on schizotypal traits) and found that ethnicity, but not migrant status, was associated with current and lifetime psychotic-like experiences. In the narrative analysis, we observed the effect of psychosocial risk factors on this association: Black ethnicity groups showed consistent increased prevalence of current and lifetime psychotic-like experiences compared with the reference population across countries.

More generalisable and standardised cohort studies of psychotic-like experiences and schizotypal traits in relation to migration/ethnicity are necessary to examine the effects of exposures and outcomes in different contexts, and to understand the underlying mechanisms of the association between subclinical psychosis and migrant and ethnic minority status.

Movement disorders associated with exposure to antipsychotic drugs are common and stigmatising but underdiagnosed.

To develop and evaluate a new clinical procedure, the ScanMove instrument, for the screening of antipsychotic-associated movement disorders for use by mental health nurses.

Item selection and content validity assessment for the ScanMove instrument were conducted by a panel of neurologists, psychiatrists and a mental health nurse, who operationalised a 31-item screening procedure. Interrater reliability was measured on ratings for 30 patients with psychosis from ten mental health nurses evaluating video recordings of the procedure. Criterion and concurrent validity were tested comparing the ScanMove instrument-based rating of 13 mental health nurses for 635 community patients from mental health services with diagnostic judgement of a movement disorder neurologist based on the ScanMove instrument and a reference procedure comprising a selection of commonly used rating scales.

Interreliability analysis showed no systematic difference between raters in their prediction of any antipsychotic-associated movement disorders category. On criterion validity testing, the ScanMove instrument showed good sensitivity for parkinsonism (90%) and hyperkinesia (89%), but not for akathisia (38%), whereas specificity was low for parkinsonism and hyperkinesia, and moderate for akathisia.

The ScanMove instrument demonstrated good feasibility and interrater reliability, and acceptable sensitivity as a mental health nurse-administered screening tool for parkinsonism and hyperkinesia.

Both internet-based cognitive–behavioural therapy (ICBT) and physical exercise are alternatives to treatment as usual (TAU) in managing mild to moderate depression in primary care.

To determine the cost-effectiveness of ICBT and physical exercise compared with TAU in primary care.

Economic evaluation of a randomised controlled trial (N = 945) in Sweden. Costs were estimated by a service use questionnaire and used together with the effects on quality-adjusted life-years (QALYs). The primary 3-month healthcare provider perspective in primary care was complemented by a 1-year societal perspective.

The primary analysis showed that incremental cost per QALY gain was €8817 for ICBT and €14 571 for physical exercise compared with TAU. At the established willingness-to-pay threshold of €21 536 (£20 000) per QALY, the probability of ICBT being cost-effective is 90%, and for physical exercise is 76%, compared with TAU.

From a primary care perspective, both ICBT and physical exercise for depression are likely to be cost-effective compared with TAU.

Sexual dysfunctions are associated with multiple medical and psychiatric disorders, as well as pharmacotherapies used to treat these disorders. Although sexual dysfunctions negatively affect both quality of life and treatment adherence, patients infrequently volunteer these symptoms and clinicians do not pose directed questions to determine their presence or severity. This issue is especially important in psychiatric patients, for whom most common psychotropics may cause sexual dysfunctions (antidepressants, antipsychotics, anxiolytics and mood-stabilising agents). There is limited literature addressing benzodiazepines, and alprazolam in particular.

To report dose-dependent alprazolam anorgasmia.

Case analysis with PubMed literature review.

A 30-year-old male psychiatric patient presented with new-onset anorgasmia in the context of asymptomatic generalised anxiety disorder, social anxiety, panic disorder with agoraphobia, obsessive–compulsive disorder, major depression in remission, and attention-deficit hyperactivity disorder treated with escitalopram 10 mg q.a.m., gabapentin 1000 mg total daily dose, lisdexamfetamine dimesylate 70 mg q.a.m., nortriptyline 60 mg q.h.s. and alprazolam extended-release 2.5 mg total daily dose. All psychotropic doses had been constant for >6 months excluding alprazolam, which was titrated from 1 mg to 2.5 mg total daily dose. The patient denied any sexual dysfunction with alprazolam at 1 mg q.d. and 1 mg b.i.d. Within 1 week of increasing alprazolam to 2.5 mg total daily dose, the patient reported anorgasmia. Anorgasmia was alprazolam dose-dependent, as anorgasmia resolved with reduced weekend dosing (1 mg b.i.d. Saturday/1.5 mg total daily dose Sunday).

Sexual dysfunction is an important adverse effect negatively influencing therapeutic outcome. This case reports alprazolam-induced dose-dependent anorgasmia. Clinicians/patients should be aware of this adverse effect. Routine sexual histories are indicated.

Common mental health problems affect a quarter of the population. Online cognitive–behavioural therapy (CBT) is increasingly used, but the factors modulating response to this treatment modality remain unclear.

This study aims to explore the demographic and clinical predictors of response to one-to-one CBT delivered via the internet.

Real-world clinical outcomes data were collected from 2211 NHS England patients completing a course of CBT delivered by a trained clinician via the internet. Logistic regression analyses were performed using patient and service variables to identify significant predictors of response to treatment.

Multiple patient variables were significantly associated with positive response to treatment including older age, absence of long-term physical comorbidities and lower symptom severity at start of treatment. Service variables associated with positive response to treatment included shorter waiting times for initial assessment and longer treatment durations in terms of the number of sessions.

Knowledge of which patient and service variables are associated with good clinical outcomes can be used to develop personalised treatment programmes, as part of a quality improvement cycle aiming to drive up standards in mental healthcare. This study exemplifies translational research put into practice and deployed at scale in the National Health Service, demonstrating the value of technology-enabled treatment delivery not only in facilitating access to care, but in enabling accelerated data capture for clinical research purposes.

Treatment for hoarding disorder is typically performed by mental health professionals, potentially limiting access to care in underserved areas.

We aimed to conduct a non-inferiority trial of group peer-facilitated therapy (G-PFT) and group psychologist-led cognitive–behavioural therapy (G-CBT).

We randomised 323 adults with hording disorder 15 weeks of G-PFT or 16 weeks of G-CBT and assessed at baseline, post-treatment and longitudinally (≥3 months post-treatment: mean 14.4 months, range 3–25). Predictors of treatment response were examined.

G-PFT (effect size 1.20) was as effective as G-CBT (effect size 1.21; between-group difference 1.82 points, t = −1.71, d.f. = 245, P = 0.04). More homework completion and ongoing help from family and friends resulted in lower severity scores at longitudinal follow-up (t = 2.79, d.f. = 175, P = 0.006; t = 2.89, d.f. = 175, P = 0.004).

Peer-led groups were as effective as psychologist-led groups, providing a novel treatment avenue for individuals without access to mental health professionals.

The prevalence and incidence of obesity are high in people with severe mental illness (SMI). In England, around 6000 people with SMI access care from secure mental health units. There is currently no specific guidance on how to reduce the risk of obesity-related morbidity and mortality in this population.

To identify international evidence that addresses the issue of obesity in mental health secure units.

A mixed method review of evidence (published 2000–2015) was carried out to assess obesity prevalence, intervention and policy change, as well as barriers to change.

Evidence from 22 mainly small, non-comparator studies (reported in 21 papers) using a range of methods was reviewed. Dietary, physical activity and cultural interventions being implemented within secure units to address the problem of obesity showed some promising outcomes for physical health and health education. These were facilitated by adequate organisational resources, staff training and motivated staff. Holistic interventions that included a social and/or competitive element were more likely to be taken up. Involving patients in decision-making mediated the tension between facilitating behaviour change and imposing control. Barriers to successful outcomes included patient movement in and out of units, severity of mental health condition and resistance to change by patients and staff.

Despite the promising outcomes reported, further assessment is needed of the feasibility, acceptability and effectiveness of interventions and policies targeting the obesogenic environment, using robust research methods.

Adolescents are digital natives, with the majority now owning their own smartphones and having internet access. Although the internet and smartphone applications (apps) can provide mental health support, little is known about how young adolescents use digital technology for mental health purposes. There are many digital health resources available for young people, but the assumption that they will be open to use them has been largely untested.

We aimed to explore how adolescents with and without raised symptoms of anxiety, depression and problematic eating use the internet on smartphones/tablets and mental health apps.

The Bristol Online Survey tool was used to deliver an online survey to 775 girls aged 11–16 years, attending a state-funded secondary school in the south-west of England. The survey was completed in class during the winter term of 2017.

A total of 98.7 and 97.4% used the internet and apps, respectively, although only 6% had used any mental health apps. Of those with raised mental health symptoms, 15–17% used or were using a mental health app, with 48.5% reporting that they would not use a mental health app.

Young female adolescents are avid users of the internet and apps but are not using digital technology for mental health purposes. Addressing concerns about digital technology are necessary to maximise the effect it can have on child and adolescent mental health.

Psychotherapy can alleviate mental distress and improve quality of life, but little is known about its potential negative effects and how to determine their frequency.

To present a commentary on the current understanding and future research directions of negative effects in psychotherapy.

An anonymous survey was distributed to a select group of researchers, using an analytical framework known as strengths, weaknesses, opportunities and threats.

The researchers perceive an increased awareness of negative effects in psychotherapy in recent years, but also discuss some of the unresolved issues in relation to their definition, assessment and reporting. Qualitative methods and naturalistic designs are regarded as important to pursue, although a number of obstacles to using such methods are identified.

Negative effects of psychotherapy are multifaceted, warranting careful considerations in order for them to be monitored and reported in research settings and routine care.

People with severe mental illness (SMI) show significantly shorter life expectancy, mostly due to more prevalent cardiovascular disease. Although age is a prominent contributor to contemporary risk assessment and SMI usually affects younger people, these assessments still do not reveal the actual risk. By assessing advanced glycation end products (AGEs), cardiovascular risk can be assessed independent of age.

To establish whether detection of AGEs with the AGE-reader will give a more accurate cardiovascular risk assessment in people with SMI.

We compared assessment with the AGE-reader with that of the Systematic Coronary Risk Evaluation (SCORE) table in a group of 120 patients with SMI.

The AGE-reader showed an increased cardiovascular risk more often than the SCORE table, especially in the youngest group.

Because of its ease of use and substantiation by studies done on other chronic diseases, we advocate use of the AGE-reader in daily care for patients with SMI to detect cardiovascular risk as early as possible. However, the findings of the current study should be evaluated with caution and should be seen as preliminary findings that require confirmation by a prospective longitudinal cohort study with a substantial follow-up observation period.
