Virtual reality (VR) has the potential to improve pain and pain-related symptoms. We examined the feasibility, acceptability, safety, and impact of a 30-min virtual underwater/sea environment (VR Blue) for reducing pain and pain-related symptoms in advanced colorectal cancer patients. A qualitative exit interview was conducted to understand preferences, thoughts, and feelings about the VR session.
Method
Participants (N = 20) had stage IV colorectal cancer and moderate-to-severe pain. Participants completed a 30-min VR Blue session that visually and aurally immersed them in virtual ocean scenarios. Feasibility was assessed by accrual (N = 20), protocol adherence (≥80% completing VR Blue), and completed data (≥80% assessment completion). Acceptability was determined by patients reporting ≥80% intervention satisfaction. Safety was determined by ≥80% of patients completing the session without self-reported side effects. Measures of pain, tension, relaxation, stress, anxiety, and mood were collected before, during, and after the VR Blue session. A semi-structured qualitative interview was conducted after VR Blue to assess participants’ VR experiences.
Results
All participants (100%) completed the VR Blue session. There was 100% data collection at the pre- and post-assessments. Satisfaction with VR Blue was high M = 3.3 (SD = 0.4) (83%). No significant side effects were reported. Pain decreased by 59% (Pre-M = 3 [1]; Post-M = 1 [1]). Tension decreased by 74% (Pre-M = 30 [24]; Post-M = 8 [13]). Relaxation improved by 38% (Pre-M = 62 [21]); Post-M = 86 [17]). Stress decreased by 68% (Pre-M = 24 [24]; Post-M = 8 [14]). Anxiety decreased by 65% (Pre-M = 20 [23]; Post-M = 7 [13]). Mood improved by 70% (Pre-M = 13 [16]; Post-M = 4 [11]). Qualitative data suggested a positive response to the VR Blue protocol.
Significance of results
This work supports the feasibility, acceptability, and safety of VR Blue for advanced colorectal cancer patients. Participants showed significant pre-post improvement in pain and pain-related symptoms hinting to the potential feasibility of VR interventions in this population. Larger, randomized trials with a control condition are needed to examine the efficacy of VR-based interventions for patients with advanced colorectal cancer and pain.
The novel coronavirus 2019 (COVID-19) has spread worldwide threatening human health. To reduce transmission, a ‘lockdown’ was introduced in Ireland between March and May 2020. The aim of this study is to capture the experiences of consultant psychiatrists during lockdown and their perception of it’s impact on mental health services.
Methods:
A questionnaire designed by the Royal College of Psychiatrists was adapted and circulated to consultant members of the College of Psychiatrists of Ireland following the easing of restrictions. The questionnaire assessed the perceived impact on referral rates, mental health act provision, availability of information technology (IT), consultant well-being and availability of personal protective equipment (PPE). Thematic analysis was employed to analyse free-text sections.
Results:
Response rate was 32% (n = 197/623). Consultants reported an initial decrease/significant decrease in referrals in the first month of lockdown (68%, n = 95/140) followed by an increase/significant increase in the second month for both new (83%, n = 100/137) and previously attending patients (65%, n = 88/136). Social isolation and reduced face-to-face mental health supports were among the main reasons identified. The needs of children and older adults were highlighted. Most consultants (76%, n = 98/129) felt their working day was affected and their well-being reduced (52%, n = 61/119). The majority felt IT equipment availability was inadequate (67%, n = 88/132). Main themes identified from free-text sections were service management, relationship between patients and healthcare service and effects on consultants’ lives.
Conclusions:
The COVID-19 pandemic has placed increased pressure on service provision and consultant wellness. This further supports the longstanding need to increase mental health service investment.
Recent literature suggests that over 70% of cases of antibody-mediated encephalitis present to psychiatry services with features of psychosis predominantly.
Aim
To investigate the seroprevalence of N-Methyl-D-Aspartate receptor antibodies (NMDAr-Ab) in patients with first episode psychosis (FEP)
Methods
Following ethical approval, all cases meeting entry criteria were invited to participate. Participants were interviewed with SCID to obtain a DSM diagnosis. NMDAr-Ab were identified in serum by cell based assay using co-transfected Human Embryonic Kidney (HEK)cells. Positive cases were reviewed by clinical neurology. Decision to treat with immunotherapy was made on a case by case basis.
Results
85/115 (72%) of patients with FEP entered the study. 49 (58%) participants were male, mean age (SD) 37 (15.7) years. 42 (52%) were outpatients at the time of assessment. Four cases (5%) were serum NMDAr-Ab positive. 3 of these cases were male, age 48 (16.3) years. All four were admitted as inpatients with normal brain MRI imaging. One case (female, 55) was confirmed as NMDAr-Ab encephalitis based on case presentation, EEG demonstrating bilateral cerebral dysfunction and NMDAr-Ab in CSF. Immunotherapy treatment lead to clinical improvement. In remaining cases, EEG was normal and CSF negative. All 3 of these cases showed clinical improvement following psychiatric treatment as usual.
Discussion
Our findings support the current estimates as to NMDAr-Ab prevalence in FEP. Increased awareness has lead to rapid treatment of florid cases of NMDAr-Ab encephalitis in our service. Additional seropositive cases are being followed with neuro-cognitive testing for any evidence of decline.
Hallucinations are classically associated with psychotic disorders. Recent
research, however, has highlighted that hallucinations frequently occur
outside of the context of psychosis. Despite this, to our knowledge, there
has been no epidemiological research to compare the prevalence of
hallucinations across common mental disorders with the prevalence in
borderline personality disorder (BPD). Using data from the Adult Psychiatric
Morbidity Survey (n = 7403), we investigated the prevalence
of hallucinations in individuals with a range of mental disorders and BPD.
Hallucinations were prevalent in all disorders (range 11–24%).
Hallucinations were no more prevalent in individuals with BPD (13.7%) than
in individuals with a (non-psychotic) mental disorder (12.6%) (χ2
= 0.03, P = 0.92).
Psychotic experiences (PE) are commonly reported in the general population, where they are associated with elevated clinical need and functional impairment. Research studies typically exclude PE that occur in the context of sleep or substance use (PE-SS), based on the assumption that they are normative within these contexts. This is the first study to formally test clinical and functional outcomes associated with PE that occur in the context of sleep or substance use.
Method
Data from the Collaborative Psychiatric Epidemiology Surveys (n = 11 776) were used to assess the associations between both PE and PE-SS and a broad range of outcomes, including psychiatric co-morbidity, suicidal behavior, mental health treatment utilization and World Health Organization (WHO) domains of function, using logistic regression analyses. Lifetime PE and PE-SS were mutually exclusive categories, assessed using the WHO Composite International Diagnostic Interview psychosis screen.
Results
PE were associated with all 10 clinical and functional outcomes. Similarly, respondents reporting PE-SS had greater clinical need and impaired function relative to controls, which was significant for seven of the 10 outcome variables. When directly compared, the PE and PE-SS groups differed only in their associations with role function (greater impairment for PE) and self-care (greater impairment for PE-SS).
Conclusions
PE-SS were associated with a broad range of clinical and functional outcomes in this large general population sample. These associations were similar to those found for PE. Future studies should investigate relative differences between sleep- and substance-induced PE.
Increasing rates of young people not in education, employment or training (NEETs) are a cause of concern both in Ireland and internationally, but little longitudinal research has examined the link between psychiatric disorder in young people and NEET status.
Methods
The Challenging Times (CT) Study is a longitudinal, population-based study of psychopathology among 212 young Irish people. Clinical interviews were performed at two time points: 12–15 years and 19–24 years.
Results
NEET status in young adulthood was associated with a sevenfold increased risk of current suicidal ideation. This result was independent of prior adolescent mental disorder. NEET young people had a fourfold increased odds of being diagnosed with a mental disorder in childhood or early adolescence compared with their economically active peers. NEET young people were at an almost threefold increased risk of any mental health disorder a twofold increased risk of anxiety disorder and threefold increased odds of suicide attempts over their lifetime compared with economically active peers.
Conclusions
NEET young people are at increased risk for mental disorder and suicidal ideation. The association is bidirectional, as prior mental disorder in adolescence appeared to account for much of the association between NEET status and current mental health problems. However, economic inactivity conveys an increased risk for suicidal ideation over and above that due to prior disorder. Our findings provide a compelling economic and societal argument for early intervention and treatment of mental disorder and the importance of vocational interventions for reducing suicide risk in young adults.
There is a lack of epidemiological research on the mental health of young adults in Ireland.
Objectives
To determine prevalence of psychiatric disorders in a cohort of young Irish adults.
Methods
The Challenging Times study was a landmark study of the prevalence of psychiatric disorders in adolescents in North Dublin, Ireland: 212 school children aged 12-15 years were recruited through schools and interviewed using the K-SADS semi-structured diagnostic instrument. This cohort was traced again at age 19-24 years (mean age 20.8 years) and interviewed using SCID I & II. Main outcome measures were current and lifetime Axis I and Axis II psychiatric disorders.
Results
Follow-up rate was 80%. Using a weighted population prevalence analysis 19.8% of the cohort had a current mental disorder, 56.0% had a lifetime mental disorder of whom 28.4% had mood disorders, 27.1% had anxiety disorders, 22.7% had substance use disorders; 25.4% had lifetime multi-morbidity. Cluster A personality disorders were found in 2.3%. Lifetime prevalence of binge-drinking was 75.0%, cannabis use 65% and 17% of young adults had fulfilled criteria for an alcohol use disorder at sometime in their life. Lifetime prevalence of suicidal thoughts/behaviour was 21.1%.
Conclusions
Lifetime prevalence of psychiatric disorder and substance use were high in this sample of young Irish adults. Mental Health service provision for this age group is a priority. Larger studies of nationally representative samples are needed to inform service development.
Psychotic symptoms, also termed psychotic-like experiences (PLEs) in the absence of psychotic disorder, are common in adolescents and are associated with increased risk of schizophrenia-spectrum illness in adulthood. At the same time, schizophrenia is associated with deficits in social cognition, with deficits particularly documented in facial emotion recognition (FER). However, little is known about the relationship between PLEs and FER abilities, with only one previous prospective study examining the association between these abilities in childhood and reported PLEs in adolescence. The current study was a cross-sectional investigation of the association between PLEs and FER in a sample of Irish adolescents.
Method
The Adolescent Psychotic-Like Symptom Screener (APSS), a self-report measure of PLEs, and the Penn Emotion Recognition-40 Test (Penn ER-40), a measure of facial emotion recognition, were completed by 793 children aged 10–13 years.
Results
Children who reported PLEs performed significantly more poorly on FER (β=−0.03, p=0.035). Recognition of sad faces was the major driver of effects, with children performing particularly poorly when identifying this expression (β=−0.08, p=0.032).
Conclusions
The current findings show that PLEs are associated with poorer FER. Further work is needed to elucidate causal relationships with implications for the design of future interventions for those at risk of developing psychosis.

The impact of climate change, in particular increasing spring temperatures, on life-cycle events of plants and animals has gained scientific attention in recent years. Leafing of trees, appearance and abundance of insects, and migration of birds, across a range of species and countries, have been cited as phenotrends that are advancing in response to warmer spring temperatures. The ability of organisms to acclimate to variations in environmental conditions is known as phenotypic plasticity. Plasticity allows organisms to time developmental stages to coincide with optimum availability of environmental resources. There may, however, come a time when the limit of this plasticity is reached and the species needs to adapt genetically to survive. Here we discuss evidence of the impact of climate warming on plant, insect and bird phenology through examination of: (1) phenotypic plasticity in (a) bud burst in trees, (b) appearance of insects and (c) migration of birds; and (2) genetic adaptation in (a) gene expression during bud burst in trees, (b) the timing of occurrence of phenological events in insects and (c) arrival and breeding times of migratory birds. Finally, we summarise the potential consequences of future climatic changes for plant, insect and bird phenology.
Introduction
The recent resurgence of interest in phenology (the timing of recurring life-cycle events in plants and animals) has stemmed from research on the impact of climate change, in particular, global warming.
Glycosylation variants of the virulent Leishmania major clone VI21 were generated by mutagenesis with N-methyl-N-nitroso-N-nitroguanidine and selected using the galactose-specific lectin Ricinus communis II (RCA II). Three mutants, 4B9, 1D1 and 1C12, which failed to bind RCA II, were found to have an altered expression of lipophosphoglycan (LPG), a molecule implicated in the attachment to host macrophages and survival within the phagolysosome. There were differences in the antigenicity, molecular weight and localization of LPG from mutant parasites as compared to V121. Expression of gp63, a surface molecule also implicated in attachment to macrophages, was unaltered. All 3 mutants caused disease when injected into genetically susceptible BALB/c mice but lesions developed at a much slower rate than those caused by the virulent V121 clone. This slow rate of lesion development did not correlate with promastigotes' ability to invade macrophages in vitro. Karyotype analysis showed that there was a reduction in the size of chromosome band number 2 in all 3 mutants. The differences in LPG and chromosome band 2 were retained by mutant clones following passage through mice, suggesting that these phenotypes are stable. Although the mutant parasites were infective and caused lesions, the changed structure of the LPG appeared to influence the virulence of the parasites.
