The heterogeneity of chronic post-COVID neuropsychiatric symptoms (PCNPS), especially after infection by the Omicron strain, has not been adequately explored.

To explore the clustering pattern of chronic PCNPS in a cohort of patients having their first COVID infection during the ‘Omicron wave’ and discover phenotypes of patients based on their symptoms’ patterns using a pre-registered protocol.

We assessed 1205 eligible subjects in Hong Kong using app-based questionnaires and cognitive tasks.

Partial network analysis of chronic PCNPS in this cohort produced two major symptom clusters (cognitive complaint–fatigue and anxiety–depression) and a minor headache–dizziness cluster, like our pre-Omicron cohort. Participants with high numbers of symptoms could be further grouped into two distinct phenotypes: a cognitive complaint–fatigue predominant phenotype and another with symptoms across multiple clusters. Multiple logistic regression showed that both phenotypes were predicted by the level of pre-infection deprivation (adjusted P-values of 0.025 and 0.0054, respectively). The severity of acute COVID (adjusted P = 0.023) and the number of pre-existing medical conditions predicted only the cognitive complaint–fatigue predominant phenotype (adjusted P = 0.003), and past suicidal ideas predicted only the symptoms across multiple clusters phenotype (adjusted P < 0.001). Pre-infection vaccination status did not predict either phenotype.

Our findings suggest that we should pursue a phenotype-driven approach with holistic biopsychosocial perspectives in disentangling the heterogeneity under the umbrella of chronic PCNPS. Management of patients complaining of chronic PCNPS should be stratified according to their phenotypes. Clinicians should recognise that depression and anxiety cannot explain all chronic post-COVID cognitive symptoms.

Nitrous oxide may possess antidepressant effects; however, limited data exist on repeated administrations and active placebo-controlled studies in treatment-resistant depression (TRD).

We aimed to test the feasibility of a randomised controlled trial examining a 4-week course of nitrous oxide or midazolam, an active placebo.

In this randomised, active, placebo-controlled pilot trial, 40 participants with TRD were assigned either a 1-h inhalation of 50% nitrous oxide plus intravenous saline (n = 20) or a 1-h inhalation of 50% oxygen plus intravenous midazolam (0.02 mg/kg, up to 2 mg; n = 20) once weekly, for 4 weeks. Feasibility was assessed by examining rates of recruitment, withdrawal, adherence, missing data and adverse events. The main measure of clinical efficacy was the change in depression severity (Montgomery–Åsberg Depression Rating Scale (MADRS)) score from baseline to day 42.

The recruitment rate was 22.3% (95% CI 16.9–29.0). Withdrawal rates were 10% (95% CI 2.8–30.1) in both groups and adherence rates were 100.0% (95% CI 82.4–100) in the nitrous oxide group and 94.4% (95% CI 74.2–99.0) in the placebo group. There were no missing primary clinical outcome data in either group (0.0%, 95% CI 0.0–17.6). MADRS score changed by −20.5% (95% CI −39.6 to −1.3) in the nitrous oxide group and −9.0% (95% CI −22.6 to 4.6) in the placebo group. Nearly all adverse events were mild to moderate and transient.

The findings support the feasibility and necessity of conducting a full-scale trial comparing nitrous oxide and midazolam in patients with TRD.

More people than ever are receiving support for mental health issues, and instances of suicide continue to grow. Although mental health funding has increased, UK government figures evidence that the National Health Service (NHS) does not have the resources required to respond to such growth in demand. The experiences of staff working in mental health services can offer insight into the efficacy of current provision and assist in service evaluation; however, research examining this issue outside of the COVID-19 pandemic, and in the context of community mental health, is lacking.

We aimed to explore the perspectives of staff working in a variety of mental health services in North-West England, to elucidate the current standard of care provided and highlight areas for improvement.

One-to-one interviews were conducted with 26 staff members as part of a qualitative grounded theory analysis.

Findings portrayed a community in crisis, consisting of the following themes: stabilisation not recovery, inefficient pathways and barriers to collaboration.

NHS services are struggling to meet the mental health needs of the population, resulting in lengthy waiting times for therapy, a lack of intervention-focused care and an over-reliance on the third sector. While crisis cafés are provided at low cost and result in satisfaction, policy-makers must ensure that these receive adequate funding and do not become overburdened. Staff reported that collaboration between clinical and non-clinical services would improve care pathways and reduce strain on the NHS, but judgemental attitudes and inflexible service development must be challenged to achieve this.

Trauma exposure has been associated with the development of psychotic disorders in adolescence and young adulthood. Trauma can compromise the sense of agency, a predictor of psychosis. Symptoms of post-traumatic stress disorder (PTSD) after trauma may also imply significant cognitive impairments that predispose young people to psychotic-like experiences (PLEs). This study investigates whether the two senses of agency subtypes – positive and negative agency, and PTSD symptoms mediated PLEs in youths after trauma.

The study aimed to explore the mediation of the sense of agency and post-traumatic stress symptoms in the development of psychotic-like experiences after trauma.

Participants were Hong Kong youths aged 12 to 25 who completed surveys online from May 2022 to May 2024. Self-report sense of agency, PLEs and related distress, potentially traumatic life events and PTSD symptoms from 517 youths with a mean age of 20.22 and 72.0% female were analysed. 283 participants (54.7%) experienced at least one potentially traumatic event.

A series of regression analyses revealed that a positive sense of agency mediated the effect of trauma on PLEs and related distress in the full sample. In the subgroup of 283 trauma-exposed youths, PTSD symptoms but not sense of agency mediated the effect of trauma on PLEs and related distress.

The presence of traumatic experiences can increase PLEs by reducing positive agency in community youths. Among trauma-exposed youths, the effect of various traumatic experiences on PLEs may be better explained by PTSD symptoms. Limitations of the study and future directions are discussed.

The rate at which psychosis drugs can be reduced in dose remains unclear. Anecdotal reports exist of people experiencing worsening of mental state before their next dose of long-acting injectable antipsychotic. No research has previously explored this phenomenon, but understanding this may advise on the rate of receptor occupancy change that provokes the emergence of psychotic symptoms.

Exploring the relationship between psychotic symptoms and variations in plasma concentration (and calculated receptor occupancy) of long-acting injectable antipsychotics.

This longitudinal study monitored mental state variation within dosing cycles of people taking depot flupentixol and zuclopenthixol. The Positive and Negative Syndrome Scale (PANSS) monitored global mental state changes, and was stratified into domains according to a five-factor model. Plasma assays at maximal and minimal concentrations allowed prediction of striatal D2 occupancy from published data. We examined correlations between receptor occupancy and the emergence of psychotic symptoms.

Preliminary results from ten participants with psychotic disorders suggest that global mental state deterioration may correlate with increased rate of D2 occupancy reduction. Increased rate of D2 occupancy reduction led to deterioration in ‘positive’ (r = 0.637 [CI: 0.013, 0.904], P = 0.047) and ‘resistance’ (r = 0.726 [CI: 0.177, 0.930], P = 0.018) PANSS clinical domains at minimal concentrations. PANSS score differences were not related to absolute reduction in D2 occupancy.

Our novel observational study design has been demonstrated to be feasible and practicable. Faster reductions in D2 occupancy may increase the risk of increased positive psychotic symptoms and irritability. Slower reductions may minimise this effect. Further recruitment is required before this can be confirmed.

Despite overlapping diagnostic criteria and aetiology, the frequency of complex post-traumatic stress disorder (C-PTSD) in people being treated for borderline personality disorder (BPD) is unknown.

To establish the frequency and correlates of probable C-PTSD in people meeting the diagnostic criteria and being treated for BPD.

C-PTSD was assessed in 87 patients meeting the diagnostic criteria for BPD and initiating treatment in out-patient personality disorder services in the UK, using the Structured Clinical Interview for DSM-IV Axis II Personality Disorders diagnostic interview, items from the Structured Interview for Disorders of Extreme Stress – Self Report and other measures. The cross-sectional association between C-PTSD and demographics, trauma and clinical variables was evaluated with logistic, ordinal and linear regression.

A total of 93% of participants reported a trauma history (95% CI 88–98%), and 57% met the criteria for probable C-PTSD (95% CI 47–67%). Previous sexual trauma increased the odds of probable C-PTSD (odds ratio 6.22, 95% CI 2.21–17.54, P < 0.001). Probable C-PTSD was associated with an increased odds of self-harm in the past 12 months (odds ratio 9.41, 95% CI 1.87–47.27, P = 0.01) and higher levels of abandonment fears (odds ratio 2.78, 95% CI 1.17–6.55, P = 0.02), abandonment–avoidant behaviour (odds ratio 4.25, 95% CI 1.30–13.91, P = 0.02) and identity instability (odds ratio 4.39, 95% CI 1.79–10.78, P < 0.01).

C-PTSD symptoms are likely to be common in people diagnosed with BPD, and are associated with higher overall psychiatric severity, with potential implications for formulation and treatment.

Bilateral sensory stimulation (BLS), such as eye movements or alternating tactile stimulation, is a key component of Eye Movement Desensitisation and Reprocessing (EMDR), a recommended treatment for post-traumatic stress disorder (PTSD). However, the neurophysiological mechanisms underlying BLS remain poorly understood.

This study examined the physiological effects of visual and tactile BLS on frontal electroencephalography (EEG) activity and autonomic arousal in patients with PTSD and healthy controls, by varying the type of stimulation in different emotional stimuli.

Twenty female PTSD patients and twenty matched healthy controls participated in a counterbalanced, within-subjects design. Participants recalled a subjectively stressful or neutral event while receiving visual or tactile BLS. Frontal EEG and peripheral psychophysiological measures were recorded before and after stimulation. Data were analysed using mixed model analysis to examine the effects of stimulation type, memory condition and group.

Both visual and tactile BLS significantly increased the total power of frontal EEG and decreased spectral edge frequency and peripheral physiological activation. These effects were consistent between the groups and memory conditions.

BLS, regardless of visual or tactile modality or emotional memory content, is associated with increased frontal EEG activity and reduced autonomic arousal. These findings support the hypothesis that BLS facilitates top-down cortical regulation, potentially aiding emotional processing in EMDR by using an inherent mechanism to promote psychological recovery. More research is needed to clarify the neural mechanisms and clinical implications.

Epilepsy is frequently accompanied by psychiatric symptoms, including mood disturbances such as depression, irritability and euphoria. Interictal dysphoric disorder (IDD), characterised by depressive and affective symptoms, is typically managed with psychiatric treatment. However, persistent symptoms, despite adequate psychiatric intervention, may indicate an underlying epileptogenic mechanism.

To highlight the importance of recognising epileptogenic contributions to persistent psychiatric symptoms, even in patients with apparently well-controlled epilepsy.

We present a case report of a Japanese woman in her 40s with well-controlled epilepsy; however, she developed enduring psychiatric symptoms. Clinical features, psychiatric treatments, neurological evaluation and therapeutic outcomes are described.

The patient experienced anxiety, depression, irritability and fear, leading to an initial diagnosis of IDD. Treatment with escitalopram and olanzapine achieved only partial symptom relief. Residual symptoms prompted further investigation, which revealed symptoms suggestive of temporal lobe epilepsy auras. Adjustment of anti-seizure therapy with lacosamide resulted in complete resolution of psychiatric symptoms, marked functional recovery and a reduction in her Hamilton Depression Rating Scale (HAMD-17) score improved from 23 to 6.

This case highlights that even in apparently well-controlled epilepsy persistent psychiatric symptoms may indicate an underlying epileptogenic mechanism rather than a primary psychiatric disorder. Careful evaluation and appropriate optimisation of anti-seizure medication can yield substantial psychiatric and functional improvements, underscoring the importance of multidisciplinary assessment in such presentations.

Non-suicidal self-injury (NSSI) displays an alarmingly high prevalence rate among university students, placing them at high risk for adverse long-term outcomes, including suicide.

This study aimed to achieve a better understanding of factors contributing to NSSI in university student populations by examining reasons for NSSI and histories of stressful events and coping strategies.

A total of 185 university students with a lifetime history of NSSI were assessed for depressive symptoms and NSSI characteristics. They completed three questionnaires on NSSI reasons, stressful events and coping strategies during childhood and adolescence. Each questionnaire included an ‘others’ option combined with an open-ended response box. After descriptive analysis of the closed questions, these open-ended responses were qualitatively categorised and analysed as predictors of depression severity and NSSI continuation from adolescence into adulthood.

Qualitative analysis identified eight, five and ten categories from the open-ended responses for NSSI reasons, stressful events and coping strategies, respectively, with substantial to almost perfect interrater reliability. Two qualitative reason categories, one stressful event category and two coping strategy categories significantly predicted depression severity (β = 0.21–0.23). Participants reporting events in the stressful events category ‘Traumatisation and experiences of violence’ were three times more likely to continue NSSI into adulthood (f 2 = 0.07).

This study demonstrates the value of mixed-methods approaches. Stable qualitative categories highlight the need to capture individual variations in NSSI-related factors. It emphasises trauma-related stressors due to their influence on depression severity and persistence of NSSI into adulthood.

To better meet the growing demand and complexity of clinical need, there is a broad international trend towards greater integration of various elements of health- and social care. However, there has been a lack of research aimed at understanding how healthcare providers have experienced these changes, including facilitators and inhibitors of integration.

This study set out to generate new understandings of this from three UK staffing ‘levels’: ‘micro’ frontline workers, a ‘meso’ level of those leading a healthcare organisation and a ‘macro’ level of commissioners.

Using Rogers’ Diffusion of Innovation framework, qualitative analysis of individual interviews from provider staff perceptions was undertaken at these three levels (total N = 33) in London.

English legislation and policy captured the need for change, but fail to describe problems or concerns of staff. There is little guidance that might facilitate learning. Staff identity, effective leadership and culture were considered critical in implementing effective integration, yet are often forgotten or ignored, compounded by an overall lack of organisational communication and learning. Cultural gains from integration with social care have largely been overlooked, but show promising opportunities in enhancing care delivery and experience.

Findings are mixed insofar as staff generally support the drivers for greater integration, but their concerns, and means for measuring change, have largely been ignored, limiting learning and optimisation of implementation. There is a need to emphasise the importance of culture and leadership in integrated care, and the benefits from closer working with social care.

The association between serum tumor necrosis factor-alpha (sTNF-α) levels and antidepressant treatment responses remains controversial.

This study aimed to examine the impact of sTNF-α levels on 12-week antidepressant treatment outcomes, and to explore the moderating effects of functional status on this relationship in patients with depressive disorders.

We measured baseline sTNF-α and evaluated functional status with the Social and Occupational Functioning Assessment Scale (SOFAS) in 1086 patients undergoing stepwise antidepressant treatment. Remission, defined as a score of ≤7 on the Hamilton Rating Scale for Depression, was assessed at 12 weeks. Logistic regression analyses were performed to adjust for relevant covariates.

Higher sTNF-α levels were significantly associated with non-remission at 12 weeks. This association was particularly evident among patients with higher SOFAS scores, whereas no significant association was observed in patients with lower SOFAS scores. The interaction between sTNF-α levels and SOFAS scores remained significant even after adjusting for relevant covariates.

Baseline sTNF-α levels may serve as a useful predictor of 12-week antidepressant treatment outcomes. Incorporating functional status into the predictive model enhances the accuracy of treatment response predictions.
