Clozapine is uniquely effective in treatment-resistant psychosis but remains underutilised, partly owing to psychotic symptoms leading to non-adherence to oral medication. An intramuscular formulation is available in the UK but outcomes remain unexplored.

This was a retrospective clinical effectiveness study of intramuscular clozapine prescription for treatment initiation and maintenance in treatment-resistant psychosis over a 3-year period.

Successful initiation of oral clozapine after intramuscular prescription was the primary outcome. Secondary outcomes included all-cause clozapine discontinuation 2 years following initiation, and 1 year after discharge. Discontinuation rates were compared with a cohort prescribed only oral clozapine. Propensity scores were used to address confounding by indication.

Among 39 patients prescribed intramuscular clozapine, 19 received at least one injection, whereas 20 accepted oral clozapine when given an enforced choice between the two. Thirty-six (92%) patients successfully initiated oral clozapine after intramuscular prescription; three never transitioned to oral. Eight discontinued oral clozapine during the 2-year follow-up, compared with 83 out of 162 in the comparator group (discontinuation rates of 24% and 50%, respectively). Discontinuation rates at 1-year post-discharge were 21%, compared with 44% in the comparison group. Intramuscular clozapine prescription was associated with a non-significantly lower hazard of discontinuation 2 years after initiation (hazard ratio 0.39, 95% CI 0.14–1.06) and 1 year after discharge (hazard ratio 0.37, 95% CI 0.11–1.24). The only reported adverse event specific to the intramuscular formulation was injection site pain and swelling.

Intramuscular clozapine prescription allowed transition to oral maintenance in an initially non-adherent cohort. Discontinuation rates were similar to patients only prescribed oral clozapine and comparable to existing literature.

Lewy body dementia, consisting of both dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD), is considerably under-recognised clinically compared with its frequency in autopsy series.

This study investigated the clinical diagnostic pathways of patients with Lewy body dementia to assess if difficulties in diagnosis may be contributing to these differences.

We reviewed the medical notes of 74 people with DLB and 72 with non-DLB dementia matched for age, gender and cognitive performance, together with 38 people with PDD and 35 with Parkinson's disease, matched for age and gender, from two geographically distinct UK regions.

The cases of individuals with DLB took longer to reach a final diagnosis (1.2 v. 0.6 years, P = 0.017), underwent more scans (1.7 v. 1.2, P = 0.002) and had more alternative prior diagnoses (0.8 v. 0.4, P = 0.002), than the cases of those with non-DLB dementia. Individuals diagnosed in one region of the UK had significantly more core features (2.1 v. 1.5, P = 0.007) than those in the other region, and were less likely to have dopamine transporter imaging (P < 0.001). For patients with PDD, more than 1.4 years prior to receiving a dementia diagnosis: 46% (12 of 26) had documented impaired activities of daily living because of cognitive impairment, 57% (16 of 28) had cognitive impairment in multiple domains, with 38% (6 of 16) having both, and 39% (9 of 23) already receiving anti-dementia drugs.

Our results show the pathway to diagnosis of DLB is longer and more complex than for non-DLB dementia. There were also marked differences between regions in the thresholds clinicians adopt for diagnosing DLB and also in the use of dopamine transporter imaging. For PDD, a diagnosis of dementia was delayed well beyond symptom onset and even treatment.

To evaluate quality of life and patient preference for schizophrenia treatment in a community based study comparing the use of aripiprazole to the standard of care (SOC).

This open-label, 26-week, multi-centre, randomised study compared aripiprazole with SOC (olanzapine, quetiapine or risperidone) in patients with schizophrenia (DSM-IV-TR criteria). The primary effectiveness variable was the mean total score of the Investigator Assessment Questionnaire (IAQ) at Week 26. The outcome research variables included the Preference of Medicine (POM) questionnaire, the Quality of Life Scale (QLS), and the EuroQoL-5D (EQ-5D). The results from these outcome research variables are the focus of this paper addressing quality of life and patient preference.

A total of 555 patients were randomised to receive aripiprazole (n = 284) or SOC (n = 271). The OC data at Week 26, reported that more respondents rated the study medication as ‘much better’ compared with their previous medication in the aripiprazole group versus SOC for patients (59% vs 35%, P < 0.001) and caregivers (58% vs 30%, P = 0.014). The improvement in QLS total score was also significantly greater in the aripiprazole group compared with SOC – mean change from baseline in QLS total score of 16.21 vs 10.01 (P < 0.001) at Week 26 (OC data set). A greater proportion of patients (93% vs 85%; P = 0.005) in the aripiprazole group had a satisfactory response on the EQ-5D Self Care Scale; all other EQ-5D scores were similar.

The study findings suggest that quality of life and patient medication preference measures were better for aripiprazole than for SOC.

High potency cannabis has been associated with greater risk, and earlier onset of psychosis. However, its effect on brain structure, particularly white matter (WM), has never been explored.

To elucidate the interplay between cannabis potency, pattern of use (frequency and age of first use) and CC microstructure; in patients with first-episode psychosis (FEP) and healthy controls.

56 FEP and 43 healthy controls underwent Diffusion-Tensor Imaging combined with WM mapping-tractography. CC was virtually dissected and segmented to calculate Fractional Anisotropy (FA), Mean Diffusivity (MD), Axial Diffusivity (AD) and Radial Diffusivity (RD) for each CC segment.

High potency cannabis users had higher Total CC MD and Total CC AD than both low potency users and those who never used (p=0.009 and p=0.02 respectively). Daily users also had higher Total CC MD and Total CC AD than both occasional users and those who never used (p=0.02 and p=0.01 respectively). Furthermore, daily/highpotency users had higher Total CC MD than those who never used or used weekly [F(2,57)=4.7, p=0.01]. There was no effect of diagnosis or diagnosis X potency/patterns of use interactions; neither differences between users who started before the age of 15 and those who started later were detected, in any diffusivity measures.

Frequent use of high-potency cannabis significantly affects callosal microstructure, regardless of the presence of a psychotic disorder. Given the increased availability and use of high potency preparations in Europe, raising awareness about some of their detrimental effects is an important avenue to pursue.

The impact of cannabis use on brain structure, particularly white matter (WM), is poorly understood. The CC is the largest WM structure in the brain. Abnormalities revealed in the CC may underlie functional anomalies of cannabis use. This is the largest study to explore the effect of cannabis on callosal WM connectivity among first episode psychosis (FEP) and controls.

To investigate the relationship between cannabis use and WM micro-structural integrity of the CC, in FEP and healthy controls.

We evaluated 56 FEP patients (67% current cannabis users), and 43 healthy controls (44% current cannabis users). We used Diffusion Tensor Imaging combined with a WM mapping-tractography technique to investigate the microstructural integrity of the CC.

Total CC Fractional anisotropy (FA) was lower in patients than controls (p=0.05). Cannabis-using patients had lower FA of the total CC than cannabis-using controls (p=0.04). There were no differences in FA between cannabis-using patients and those who had never used. However, cannabis-using patients had higher mean diffusivity (MD) of total CC (p= 0.02), Rostral-Body (p=0.003), Anterior Mid-Body (p=0.03) and the Splenium (p=0.06) than patients who never used cannabis. There were no differences in MD between patient users who started before the age of 16 and those who started later.

Cannabis is associated with a significant effect on callosal WM integrity only in patients with psychosis. Disturbed callosal connectivity may explain some of the abnormalities with regard to the functional and clinical outcomes in FEP cannabis users, including measures of cognitive impairment.

Psychosocial interventions that mitigate psychosocial distress in cancer patients are important. The primary aim of this study was to examine the feasibility and acceptability of an adaptation of the Mindful Self-Compassion (MSC) program among adult cancer patients. A secondary aim was to examine pre–post-program changes in psychosocial wellbeing.

The research design was a feasibility and acceptability study, with an examination of pre- to post-intervention changes in psychosocial measures. A study information pack was posted to 173 adult cancer patients 6 months–5 years post-diagnosis, with an invitation to attend an eight-week group-based adaptation of the MSC program.

Thirty-two (19%) consented to the program, with 30 commencing. Twenty-seven completed the program (mean age: 62.93 years, SD 14.04; 17 [63%] female), attending a mean 6.93 (SD 1.11) group sessions. There were no significant differences in medico-demographic factors between program-completers and those who did not consent. However, there was a trend toward shorter time since diagnosis in the program-completers group. Program-completers rated the program highly regarding content, relevance to the concerns of cancer patients, and the likelihood of recommending the program to other cancer patients. Sixty-three percent perceived that their mental wellbeing had improved from pre- to post-program; none perceived a deterioration in mental wellbeing. Small-to-medium effects were observed for depressive symptoms, fear of cancer recurrence, stress, loneliness, body image satisfaction, mindfulness, and self-compassion.

The MSC program appears feasible and acceptable to adults diagnosed with non-advanced cancer. The preliminary estimates of effect sizes in this sample suggest that participation in the program was associated with improvements in psychosocial wellbeing. Collectively, these findings suggest that there may be value in conducting an adequately powered randomized controlled trial to determine the efficacy of the MSC program in enhancing the psychosocial wellbeing of cancer patients.

The first episode of psychosis is a critical period in the emergence of cardiometabolic risk.

We set out to explore the influence of individual and lifestyle factors on cardiometabolic outcomes in early psychosis.

This was a prospective cohort study of 293 UK adults presenting with first-episode psychosis investigating the influence of sociodemographics, lifestyle (physical activity, sedentary behaviour, nutrition, smoking, alcohol, substance use) and medication on cardiometabolic outcomes over the following 12 months.

Rates of obesity and glucose dysregulation rose from 17.8% and 12%, respectively, at baseline to 23.7% and 23.7% at 1 year. Little change was seen over time in the 76.8% tobacco smoking rate or the quarter who were sedentary for over 10 h daily. We found no association between lifestyle at baseline or type of antipsychotic medication prescribed with either baseline or 1-year cardiometabolic outcomes. Median haemoglobin A1c (HbA1c) rose by 3.3 mmol/mol in participants from Black and minority ethnic (BME) groups, with little change observed in their White counterparts. At 12 months, one-third of those with BME heritage exceeded the threshold for prediabetes (HbA1c >39 mmol/mol).

Unhealthy lifestyle choices are prevalent in early psychosis and cardiometabolic risk worsens over the next year, creating an important window for prevention. We found no evidence, however, that preventative strategies should be preferentially directed based on lifestyle habits. Further work is needed to determine whether clinical strategies should allow for differential patterns of emergence of cardiometabolic risk in people of different ethnicities.

In March 2017, the New Jersey Department of Health received reports of 3 patients who developed septic arthritis after receiving intra-articular injections for osteoarthritis knee pain at the same private outpatient facility in New Jersey. The risk of septic arthritis resulting from intra-articular injection is low. However, outbreaks of septic arthritis associated with unsafe injection practices in outpatient settings have been reported.

An infection prevention assessment of the implicated facility’s practices was conducted because of the ongoing risk to public health. The assessment included an environmental inspection of the facility, staff interviews, infection prevention practice observations, and a medical record and office document review. A call for cases was disseminated to healthcare providers in New Jersey to identify patients treated at the facility who developed septic arthritis after receiving intra-articular injections.

We identified 41 patients with septic arthritis associated with intra-articular injections. Cultures of synovial fluid or tissue from 15 of these 41 case patients (37%) recovered bacteria consistent with oral flora. The infection prevention assessment of facility practices identified multiple breaches of recommended infection prevention practices, including inadequate hand hygiene, unsafe injection practices, and poor cleaning and disinfection practices. No additional cases were identified after infection prevention recommendations were implemented by the facility.

Aseptic technique is imperative when handling, preparing, and administering injectable medications to prevent microbial contamination.

This investigation highlights the importance of adhering to infection prevention recommendations. All healthcare personnel who prepare, handle, and administer injectable medications should be trained in infection prevention and safe injection practices.

Medication with anticholinergic action is associated with potentially serious adverse effects in older people. We present an evaluation of a novel anticholinergic burden scale introduced into routine practice in older adult services in the South London and Maudsley (SLaM) NHS Foundation Trust. Our aim was to assess whether this tool improved the accurate identification of anticholinergic medication and guided safer prescribing in cognitively vulnerable older people.

The introduction of the anticholinergic effect on cognition (AEC) tool into clinical practice led to an increase in the identification and reporting to general practitioners of anticholinergic medication from 11 to 85% of cases (P = 0.0015).

Application of the AEC tool led to improved detection of anticholinergic medication and advice to primary care on when a medication review is necessary. This is an important step towards improving the safety of prescribing in this patient group.
