Patients with posttraumatic stress disorder (PTSD) exhibit smaller regional brain volumes in commonly reported regions including the amygdala and hippocampus, regions associated with fear and memory processing. In the current study, we have conducted a voxel-based morphometry (VBM) meta-analysis using whole-brain statistical maps with neuroimaging data from the ENIGMA-PGC PTSD working group.

T1-weighted structural neuroimaging scans from 36 cohorts (PTSD n = 1309; controls n = 2198) were processed using a standardized VBM pipeline (ENIGMA-VBM tool). We meta-analyzed the resulting statistical maps for voxel-wise differences in gray matter (GM) and white matter (WM) volumes between PTSD patients and controls, performed subgroup analyses considering the trauma exposure of the controls, and examined associations between regional brain volumes and clinical variables including PTSD (CAPS-4/5, PCL-5) and depression severity (BDI-II, PHQ-9).

PTSD patients exhibited smaller GM volumes across the frontal and temporal lobes, and cerebellum, with the most significant effect in the left cerebellum (Hedges’ g = 0.22, pcorrected = .001), and smaller cerebellar WM volume (peak Hedges’ g = 0.14, pcorrected = .008). We observed similar regional differences when comparing patients to trauma-exposed controls, suggesting these structural abnormalities may be specific to PTSD. Regression analyses revealed PTSD severity was negatively associated with GM volumes within the cerebellum (pcorrected = .003), while depression severity was negatively associated with GM volumes within the cerebellum and superior frontal gyrus in patients (pcorrected = .001).

PTSD patients exhibited widespread, regional differences in brain volumes where greater regional deficits appeared to reflect more severe symptoms. Our findings add to the growing literature implicating the cerebellum in PTSD psychopathology.

This study aimed to assess whether frailty (measured using the 5-Item Modified Frailty Index) was associated with increased morbidity following surgical tracheostomy.

A single-centre retrospective cohort study analysed a prospectively maintained database between 2022 and 2023. Univariable and multivariable regressions were used to determine factors (including frailty) associated with increased morbidity.

A total of 174 patients underwent surgical tracheostomy in the study period with 28 patients determined as frail (16.1 per cent). Overall, 21 patients (12.1 per cent) suffered a tracheostomy-specific complication. Multivariable regression found an association between frail patient status and increased tracheostomy-specific complications (odds ratio 4.09, 95 per cent confidence interval 1.51–11.11; p = 0.006) and longer hospital length of stay (β 15.76 days, 95 per cent confidence interval 1.06–30.44; p = 0.036).

Frailty was associated with increased morbidity and longer hospital stay following tracheostomy. Assessment of frailty may guide decision making and patient discussions when planning tracheostomy.

Obsessive–compulsive disorder (OCD) is a psychiatric condition leading to significant distress and poor quality of life. Successful treatment of OCD is restricted by the limited knowledge about its pathophysiology. This study aimed to investigate the pathophysiology of OCD using electroencephalographic (EEG) event-related potentials (ERPs), elicited from multiple tasks to characterise disorder-related differences in underlying brain activity across multiple neural processes.

ERP data were obtained from 25 OCD patients and 27 age- and sex-matched healthy controls (HCs) by recording EEG during flanker and go/nogo tasks. Error-related negativity (ERN) was elicited by the flanker task, while N200 and P300 were generated using the go/nogo task. Primary comparisons of the neural response amplitudes and the topographical distribution of neural activity were conducted using scalp field differences across all time points and electrodes.

Compared to HCs, the OCD group showed altered ERP distributions. Contrasting with the previous literature on ERN and N200 topographies in OCD where fronto-central negative voltages were reported, we detected positive voltages. Additionally, the P300 was found to be less negative in the frontal regions. None of these ERP findings were associated with OCD symptom severity.

These results indicate that individuals with OCD show altered frontal neural activity across multiple executive function-related processes, supporting the frontal dysfunction theory of OCD. Furthermore, due to the lack of association between altered ERPs and OCD symptom severity, they may be considered potential candidate endophenotypes for OCD.

Objective structured clinical examinations (OSCEs) play a pivotal role in medical education assessment. The Advanced Clinical Skills (ACS) OSCE examines clinical skills in psychiatry, general practice, obstetrics and gynaecology and paediatrics. This study examined if the 2020 ACS OSCE for fourth year medical students attending the National University of Ireland, Galway, was associated with any significant result differences compared to the equivalent 2019 OSCE. Additionally, we assessed students’ satisfaction and explored any organisational difficulties in conducting a face-to-face OSCE during the COVID-19 pandemic.

This study compared anonymised data between the 2019 and 2020 ACS OSCEs and analysed anonymised student feedback pertaining to the modified 2020 OSCE.

The mean total ACS OSCE result achieved in 2020 was statistically higher compared to the 2019 OSCE [62.95% (SD = 6.21) v. 59.35% (SD = 5.54), t = 6.092, p < 0.01], with higher marks noted in psychiatry (p = 0.001), paediatrics (p = 0.001) and general practice (p < 0.001) with more students attaining honours grades (χ2 = 27.257, df = 3, p < 0.001). No difference in failure rates were found. Students reported feeling safe performing the 2020 OSCE (89.2%), but some expressed face-mask wearing impeded their communication skills (47.8%).

This study demonstrates that conducting a face-to-face OSCE during the pandemic is feasible and associated with positive student feedback. Exam validity has been demonstrated as there was no difference in the overall pass rate.

To report feasibility, early outcomes and challenges of implementing a 14-day threshold for undertaking surgical tracheostomy in the critically ill coronavirus disease 2019 patient.

Twenty-eight coronavirus disease 2019 patients underwent tracheostomy. Demographics, risk factors, ventilatory assistance, organ support and logistics were assessed.

The mean time from intubation to tracheostomy formation was 17.0 days (standard deviation = 4.4, range 8–26 days). Mean time to decannulation was 15.8 days (standard deviation = 9.4) and mean time to intensive care unit stepdown to a ward was 19.2 days (standard deviation = 6.8). The time from intubation to tracheostomy was strongly positively correlated with: duration of mechanical ventilation (r(23) = 0.66; p < 0.001), time from intubation to decannulation (r(23) = 0.66; p < 0.001) and time from intubation to intensive care unit discharge (r(23) = 0.71; p < 0.001).

Performing a tracheostomy in coronavirus disease 2019 positive patients at 8–14 days following intubation is compatible with favourable outcomes. Multidisciplinary team input is crucial to patient selection.

Background Attention-deficit/hyperactivity disorder (ADHD) is among the most common psychiatric disorders of childhood that often persists into adulthood and old age. Yet ADHD is currently underdiagnosed and undertreated in many European countries, leading to chronicity of symptoms and impairment, due to lack of, or ineffective treatment, and higher costs of illness.

Methods The European Network Adult ADHD and the Section for Neurodevelopmental Disorders Across the Lifespan (NDAL) of the European Psychiatric Association (EPA), aim to increase awareness and knowledge of adult ADHD in and outside Europe. This Updated European Consensus Statement aims to support clinicians with research evidence and clinical experience from 63 experts of European and other countries in which ADHD in adults is recognized and treated.

Results Besides reviewing the latest research on prevalence, persistence, genetics and neurobiology of ADHD, three major questions are addressed: (1) What is the clinical picture of ADHD in adults? (2) How should ADHD be properly diagnosed in adults? (3) How should adult ADHDbe effectively treated?

Conclusions ADHD often presents as a lifelong impairing condition. The stigma surrounding ADHD, mainly due to lack of knowledge, increases the suffering of patients. Education on the lifespan perspective, diagnostic assessment, and treatment of ADHD must increase for students of general and mental health, and for psychiatry professionals. Instruments for screening and diagnosis of ADHD in adults are available, as are effective evidence-based treatments for ADHD and its negative outcomes. More research is needed on gender differences, and in older adults with ADHD.

This study aims to investigate existing evidence for the effectiveness of psychological treatments and/or antidepressant medication as a treatment for those diagnosed with moderate levels of depression.

A PRISMA systematic review of articles using electronic research databases (2000–2014) was conducted to identify studies investigating the effectiveness of psychotherapy and/or medication as a treatment for people with moderate levels of depression. Search terms included moderate depression, psychotherapy and/or medication, depressive disorders, antidepressants, psychotherapy, mental health services, and randomized-controlled trial (RCT). The included studies were then assessed, extracted, and synthesised.

A total of 14 studies met the inclusion criteria (11 RCTs and three additional studies) for this review. The findings of the systematic review indicate that there is limited evidence available specific to the treatment of moderate depression and that this research seems to suggest that psychotherapy or combined treatment has a beneficial effect.

Given that depression is one of the biggest challenges the world faces at present, further research is required to examine the effectiveness of treatment for different levels of depression severity.

The aim of this study is to examine the risk and protective factors associated with anxiety and depression in a representative sample of Irish adolescents.

Data used in this study were drawn from a subset of the My World Survey (MWS). The MWS-Second Level (MWS-SL) subset consists of a randomised sample of 72 schools, with a final sample of 6085 students. Outcome measures were depression and anxiety. Risk and protective factors included measures within the socio-demographic, psychosocial and risk-taking domains.

One in three adolescents experienced elevated levels of depression and anxiety. Age, gender, maternal education, family composition, parental mental health as well as the experience of racism and bereavement were associated with elevated distress. Psychosocial factors associated with depression and anxiety included optimism, personal competence, life-satisfaction, self-esteem, anger, body dissatisfaction, family competence, maternal and paternal criticism, experiencing the break-up of a romantic relationship, school and peer connectedness as well as the availability of one good adult. Finally, engaging in substance misuse was found to increase the likelihood of anxiety and depression.

Since factors protecting and putting adolescents at risk of anxiety and depression exist at every level of the adolescent’s ecological system, the study supports a community-based approach to youth mental health.
