Sleep problems associated with poor mental health and academic outcomes may have been exacerbated by the COVID-19 pandemic.
Aims
To describe sleep in undergraduate students during the COVID-19 pandemic.
Method
This longitudinal analysis included data from 9523 students over 4 years (2018–2022), associated with different pandemic phases. Students completed a biannual survey assessing risk factors, mental health symptoms and lifestyle, using validated measures. Sleep was assessed with the Sleep Condition Indicator (SCI-8). Propensity weights and multivariable log-binomial regressions were used to compare sleep in four successive first-year cohorts. Linear mixed-effects models were used to examine changes in sleep over academic semesters and years.
Results
There was an overall decrease in average SCI-8 scores, indicating worsening sleep across academic years (average change −0.42 per year; P-trend < 0.001), and an increase in probable insomnia at university entry (range 18.1–29.7%; P-trend < 0.001) before and up to the peak of the pandemic. Sleep improved somewhat in autumn 2021, when restrictions loosened. Students commonly reported daytime sleep problems, including mood, energy, relationships (36–48%) and concentration, productivity, and daytime sleepiness (54–66%). There was a consistent pattern of worsening sleep over the academic year. Probable insomnia was associated with increased cannabis use and passive screen time, and reduced recreation and exercise.
Conclusions
Sleep difficulties are common and persistent in students, were amplified by the pandemic and worsen over the academic year. Given the importance of sleep for well-being and academic success, a preventive focus on sleep hygiene, healthy lifestyle and low-intensity sleep interventions seems justified.
International guidelines recommend that prospective organ transplant patients receive a psychosocial assessment to optimise outcomes. There is limited consensus regarding the criteria for psychosocial evaluation. The Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) tool was developed to enhance the pre-transplant psychosocial workup. The Mater Hospital is the National Centre for heart and lung transplantation in Ireland. The consultation-liaison psychiatry (CLP) service provides screening of pre-transplant candidates using a biopsychosocial assessment, SIPAT and cognitive screening tools. Post-transplant patients are reviewed on a referral basis.
Objectives
To identify the psychosocial needs of heart and lung transplant recipients and CLP service input over a one year period.
Methods
A review of all heart and lung transplant recipients between January 1st and December 31st 2021 was conducted. The following data were recorded: demographics, pre-existing mental illness, SIPAT scores, and referral to the CLP service within six months of transplantation.
Results
Twenty-eight individuals received a heart/lung transplant in 2021 (7 heart, 19 lung, 1 heart &liver, 1 heart & lung). Prior to transplant 50% (14/28) had a pre-existing mental health diagnosis, 7% (2/28) had attended a psychiatrist, and 28.6% (8/28) were on psychotropic medication. SIPAT scores were available for 20 patients. The overall mean SIPAT score was 10.8 (SD 6.1). The subscales were as follows: Patient Readiness, mean 3.2 (SD 1.7); Social Support System, mean 2.1 (SD: 1.8); Psychological Stability & Psychopathology, mean 1.6 (SD 2.7); and Lifestyle & Substance Misuse, mean 3 (SD 1.5). Based on SIPAT scores, 20% (4/20) were excellent candidates, 75% (15/20) were good candidates and 1 (1/20) was minimally acceptable. Pre-existing mental illness was associated with higher total SIPAT scores (p=0.013) and higher scores on the psychological stability subscale (p=0.032). Post-transplant, 50% (14/28) were referred for psychological support and 21.4% (6/28) were referred to the CLP service. A further 10.7% (n=3) were attending CLP prior to transplant. Referrals to CLP occurred (median) 13 days (range 1-275) post-transplant surgery. The reasons for attending CLP were anxiety (5/9), delirium (3/9) and mood (1/9).
Conclusions
SIPAT can be a valuable tool for use in the pre-transplant workup to help identify those that will require intensive psychosocial support post- transplant.
Perfectionism, low self-esteem and external locus of control are psychological constructs linked to insomnia, anxiety and depression. Examining how these constructs impact mental health and serve as risk factors for the development of clinically significant symptoms may help direct psychological support resources and preventative measures for university students.
Aims
To longitudinally examine associations between the aforementioned psychological constructs and symptoms of insomnia, anxiety and depression in a large representative sample of first-year university students.
Method
Electronic surveys including validated measures of the predictors and outcomes were emailed to all first-year undergraduate students at entry to a major Canadian university, and followed up on at conclusion of the academic year.
Results
Compared with healthy sleepers, students screening positive for insomnia had lower self-esteem, higher self-evaluative perfectionism and increased external locus of control (all P < 0.001). Self-evaluative perfectionism (standardised β = 0.13, P < 0.01), self-esteem (β = −0.30, P < 0.001) and external locus of control (β = 0.07, P = 0.02) measured at entry were significantly associated with insomnia symptoms at follow-up. Insomnia symptoms at entry were strong predictors of symptoms of depression (β = 0.15, P < 0.001) and anxiety (β = 0.16, P < 0.001) at follow-up, even after controlling for baseline symptoms of those disorders.
Conclusions
Perfectionism, low self-esteem and external locus of control may predispose the development of insomnia symptoms in university students. In turn, insomnia symptoms appear to be robust predictors for depressive and anxiety symptoms. Sleep may be an important prevention target in university students.
Novel, evidence-based treatments are required for treatment-resistant post-traumatic stress disorder (PTSD). 3,4-Methylenedioxymethamphetamine (MDMA) has beneficially augmented psychotherapy in several small clinical trials.
Objectives
To review the use of MDMA-assisted psychotherapy in treatment-resistant PTSD.
Methods
Systematic searches of four databases were conducted from inception to February 2020. A meta-analysis was performed on trials which were double-blinded, randomised, and compared MDMA-assisted psychotherapy to psychotherapy and placebo. The primary outcomes were the differences in Clinician Administered PTSD Scale (CAPS-IV) score and Beck’s Depression Inventory (BDI). Secondary outcome measures included neurocognitive and physical adverse effects, at the time, and within seven days of intervention.
Results
Four randomised controlled trials (RCTs) met inclusion criteria. When compared to active placebo, intervention groups taking 75mg (MD -46.90; 95% CI -58.78, -35.02), 125mg (MD -20.98; 95% CI -34.35, -7.61) but not 100mg (MD -12.90; 95% CI -36.09, 10.29) of MDMA with psychotherapy, had significant decreases in CAPS-IV scores, as did the inactive placebo arm (MD -33.20; 95% CI -40.53, -25.87). A significant decrease in BDI when compared to active placebo (MD -10.80; 95% CI -20.39, -1.21) was only observed at 75mg. Compared to placebo, participants reported significantly more episodes of low mood, nausea and jaw-clenching during sessions and lack of appetite after seven days.
Conclusions
These results demonstrate potential therapeutic benefit with minimal physical and neurocognitive risk for the use of MDMA-assisted psychotherapy in TR-PTSD, despite little effect on Beck’s Depression Inventory. Better powered RCTs are required to investigate further.

We have adapted the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) Science Pipelines to process data from the Gravitational-wave Optical Transient Observer (GOTO) prototype. In this paper, we describe how we used the LSST Science Pipelines to conduct forced photometry measurements on nightly GOTO data. By comparing the photometry measurements of sources taken on multiple nights, we find that the precision of our photometry is typically better than 20 mmag for sources brighter than 16 mag. We also compare our photometry measurements against colour-corrected Panoramic Survey Telescope and Rapid Response System photometry and find that the two agree to within 10 mmag (1$\sigma$) for bright (i.e., $\sim 14{\rm th} \mathrm{mag}$) sources to 200 mmag for faint (i.e., $\sim 18{\rm th} \mathrm{mag}$) sources. Additionally, we compare our results to those obtained by GOTO’s own in-house pipeline, gotophoto, and obtain similar results. Based on repeatability measurements, we measure a $5\sigma$L-band survey depth of between 19 and 20 magnitudes, depending on observing conditions. We assess, using repeated observations of non-varying standard Sloan Digital Sky Survey stars, the accuracy of our uncertainties, which we find are typically overestimated by roughly a factor of two for bright sources (i.e., $< 15{\rm th} \mathrm{mag}$), but slightly underestimated (by roughly a factor of 1.25) for fainter sources ($> 17{\rm th} \mathrm{mag}$). Finally, we present lightcurves for a selection of variable sources and compare them to those obtained with the Zwicky Transient Factory and GAIA. Despite the LSST Software Pipelines still undergoing active development, our results show that they are already delivering robust forced photometry measurements from GOTO data.
Concerns have been raised about the utility of self-report assessments in predicting future suicide attempts. Clinicians in pediatric emergency departments (EDs) often are required to assess suicidal risk. The Death Implicit Association Test (IAT) is an alternative to self-report assessment of suicidal risk that may have utility in ED settings.
Methods
A total of 1679 adolescents recruited from 13 pediatric emergency rooms in the Pediatric Emergency Care Applied Research Network were assessed using a self-report survey of risk and protective factors for a suicide attempt, and the IAT, and then followed up 3 months later to determine if an attempt had occurred. The accuracy of prediction was compared between self-reports and the IAT using the area under the curve (AUC) with respect to receiver operator characteristics.
Results
A few self-report variables, namely, current and past suicide ideation, past suicidal behavior, total negative life events, and school or social connectedness, predicted an attempt at 3 months with an AUC of 0.87 [95% confidence interval (CI), 0.84–0.90] in the entire sample, and AUC = 0.91, (95% CI 0.85–0.95) for those who presented without reported suicidal ideation. The IAT did not add significantly to the predictive power of selected self-report variables. The IAT alone was modestly predictive of 3-month attempts in the overall sample ((AUC = 0.59, 95% CI 0.52–0.65) and was a better predictor in patients who were non-suicidal at baseline (AUC = 0.67, 95% CI 0.55–0.79).
Conclusions
In pediatric EDs, a small set of self-reported items predicted suicide attempts within 3 months more accurately than did the IAT.
The past few decades have seen the burgeoning of wide-field, high-cadence surveys, the most formidable of which will be the Legacy Survey of Space and Time (LSST) to be conducted by the Vera C. Rubin Observatory. So new is the field of systematic time-domain survey astronomy; however, that major scientific insights will continue to be obtained using smaller, more flexible systems than the LSST. One such example is the Gravitational-wave Optical Transient Observer (GOTO) whose primary science objective is the optical follow-up of gravitational wave events. The amount and rate of data production by GOTO and other wide-area, high-cadence surveys presents a significant challenge to data processing pipelines which need to operate in near-real time to fully exploit the time domain. In this study, we adapt the Rubin Observatory LSST Science Pipelines to process GOTO data, thereby exploring the feasibility of using this ‘off-the-shelf’ pipeline to process data from other wide-area, high-cadence surveys. In this paper, we describe how we use the LSST Science Pipelines to process raw GOTO frames to ultimately produce calibrated coadded images and photometric source catalogues. After comparing the measured astrometry and photometry to those of matched sources from PanSTARRS DR1, we find that measured source positions are typically accurate to subpixel levels, and that measured L-band photometries are accurate to $\sim50$ mmag at $m_L\sim16$ and $\sim200$ mmag at $m_L\sim18$. These values compare favourably to those obtained using GOTO’s primary, in-house pipeline, gotophoto, in spite of both pipelines having undergone further development and improvement beyond the implementations used in this study. Finally, we release a generic ‘obs package’ that others can build upon, should they wish to use the LSST Science Pipelines to process data from other facilities.
The treatment of mental illness is undergoing a paradigm shift, moving away from involuntary treatments towards rights-based, patient-centred care. However, rates of seclusion and restraint in Ireland are on the rise. The World Health Organisation’s QualityRights initiative aims to remove coercion from the practice of mental health care, in order to concord with the Convention on the Rights of Persons with Disabilities. The QualityRights initiative has recently published a training programme, with eight modules designed to be delivered as workshops. Conducting these workshops may reduce coercive practices, and four of the modules may be of particular relevance for Ireland. The ‘Supported decision-making and advance planning’ and the ‘Legal capacity and the right to decide’ modules highlight the need to implement the Assisted Decision-Making (Capacity) Act, 2015, while the ‘Freedom from coercion, violence and abuse’ and ‘Strategies to end seclusion and restraint’ modules describe practical alternatives to some current involuntary treatments.
In product design engineering (PDE), ideation involves the generation of technical behaviours and physical structures to address specific functional requirements. This differs from generic creative ideation tasks, which emphasise functional and technical considerations less. To advance knowledge about the neural basis of PDE ideation, we present the first fMRI study on professional product design engineers practising in industry. We aimed to explore brain activation during ideation, and compare activation in open-ended and constrained tasks. Imagery manipulation tasks were contrasted with ideation tasks in a sample of 29 PDE professionals. The key findings were: (1) PDE ideation is associated with greater activity in left cingulate gyrus; (2) there were no significant differences between open-ended and constrained tasks; and (3) a preliminary association with activity in the right superior temporal gyrus was also observed. The results are consistent with existing fMRI work on generic creative ideation, suggesting that PDE ideation may share a number of similarities at the neural level. Future work includes: functional connectivity analysis of open-ended and constrained ideation to further investigate potential differences; investigating the effects of aspects of design expertise/training on processing; and the use of novelty measures directly linked to the designer’s internal processing in fMRI analysis.
As a catalyst for thinking about what an affective life might be and how such a life might be intimately bound up with its relations to its surroundings or environment, I propose in this chapter to present two different ways of thinking about individuality in Spinoza. I do so in order to draw out what is at stake in a double point of view of the degree of the power to act of a singular thing in Spinoza's Ethics. Sometimes this power to act seems to be fixed to a precisely determined degree, whereas sometimes it seems to admit a certain degree of variation. The problem of how to resolve this apparent contradiction has generated varying interpretations among scholars in Spinoza studies, including Martial Gueroult (1974), Gilles Deleuze (1992), Pierre Macherey (1995), and Charles Ramond (1995). The problem cannot be addressed in isolation from two other equally perplexing questions: whether the essence of a singular thing remains fixed or should be understood to be variable; and whether the conatus, as the expression of the power to act of a singular thing, should be understood to remain fixed or to be variable. These three questions are related because the three aspects of Spinoza's philosophy with which they deal – the power to act, modal essence, and conatus – are intimately intertwined, the interpretation of one having a bearing on the interpretation of the others. For a more precise understanding of these different ways of variation, and to render them compatible with each other, it is necessary to commence with the question of the variation of the essences of singular things. Certain interpreters, such as Gueroult, consider these essences to be situated between a ‘minimum’ and a ‘maximum’, and that it is only above or below this range that a rupture occurs in an individual's identity, resulting in a change of the individual's structure and therefore of its nature (Gueroult 1974: 351).
In Quantité et qualité dans la philosophie de Spinoza, by contrast, Charles Ramond argues that the essence of a singular thing is determined by a ‘precise relation’ of movement and rest, or by a quantum of the power to act of the conatus, and all variation is prohibited, since any augmentation or diminution of this power to act would create another individual.
As a pilot study to investigate whether personalized medicine approaches could have value for the reduction of malaria-related mortality in young children, we evaluated questionnaire and biomarker data collected from the Mother Offspring Malaria Study Project birth cohort (Muheza, Tanzania, 2002–2006) at the time of delivery as potential prognostic markers for pediatric severe malarial anemia. Severe malarial anemia, defined here as a Plasmodium falciparum infection accompanied by hemoglobin levels below 50 g/L, is a key manifestation of life-threatening malaria in high transmission regions. For this study sample, a prediction model incorporating cord blood levels of interleukin-1β provided the strongest discrimination of severe malarial anemia risk with a C-index of 0.77 (95% CI 0.70–0.84), whereas a pragmatic model based on sex, gravidity, transmission season at delivery, and bed net possession yielded a more modest C-index of 0.63 (95% CI 0.54–0.71). Although additional studies, ideally incorporating larger sample sizes and higher event per predictor ratios, are needed to externally validate these prediction models, the findings provide proof of concept that risk score-based screening programs could be developed to avert severe malaria cases in early childhood.
Culturomics is the study of behaviour and culture through quantitative analysis of digitised text. We aimed to apply a modern technique in this field to examine trends related to the history of psychiatry. In doing so, we aimed to explore the nature of the Google Ngram methodology.
Methods
Using Google Ngram Viewer, we studied Google’s corpus of over 4% of all published books and explored relevant trends in word usage.
Results
An exponential growth in the use of ‘psychiatry’ between 1890 and 1984 was identified. ‘Sigmund Freud’ was mentioned more frequently than all other prominent figures in the history of psychiatry combined. Mentions of ‘suicide’ increased since 1820. The impact of several DSM editions is discussed.
Conclusion
This study demonstrated the potential application of the Ngram methodology to the study of the history of psychiatry. The role of textual analysis in this field merits careful, constructive consideration and is likely to expand with technological advances.
This paper reports findings from the first systematic review of protocol studies focusing specifically on conceptual design cognition, aiming to answer the following research question: What is our current understanding of the cognitive processes involved in conceptual design tasks carried out by individual designers? We reviewed 47 studies on architectural design, engineering design and product design engineering. This paper reports 24 cognitive processes investigated in a subset of 33 studies aligning with two viewpoints on the nature of designing: (V1) design as search (10 processes, 41.7%); and (V2) design as exploration (14 processes, 58.3%). Studies on search focused on solution search and problem structuring, involving: long-term memory retrieval; working memory; operators and reasoning processes. Studies on exploration investigated: co-evolutionary design; visual reasoning; cognitive actions; and unexpected discovery and situated requirements invention. Overall, considerable conceptual and terminological differences were observed among the studies. Nonetheless, a common focus on memory, semantic, associative, visual perceptual and mental imagery processes was observed to an extent. We suggest three challenges for future research to advance the field: (i) developing general models/theories; (ii) testing protocol study findings using objective methods conducive to larger samples and (iii) developing a shared ontology of cognitive processes in design.
Towards addressing ontological issues in design cognition research, this paper presents the first generic classification of cognitive processes investigated in protocol studies on conceptual design cognition. The classification is based on a systematic review of 47 studies published over the past 30 years. Three viewpoints on the nature of design cognition are outlined (search, exploration and design activities), highlighting considerable differences in the concepts and terminology applied to describe cognition. To provide a more unified view of the cognitive processes fundamentally under study, we map specific descriptions of cognitive processes provided in protocol studies to more generic, established definitions in the cognitive psychology literature. This reveals a set of 6 categories of cognitive process that appear to be commonly studied and are therefore likely to be prevalent in conceptual design: (1) long-term memory; (2) semantic processing; (3) visual perception; (4) mental imagery processing; (5) creative output production and (6) executive functions. The categories and their constituent processes are formalised in the generic classification. The classification provides the basis for a generic, shared ontology of cognitive processes in design that is conceptually and terminologically consistent with the ontology of cognitive psychology and neuroscience. In addition, the work highlights 6 key avenues for future empirical research: (1) the role of episodic and semantic memory; (2) consistent definitions of semantic processes; (3) the role of sketching from alternative theoretical perspectives on perception and mental imagery; (4) the role of working memory; (5) the meaning and nature of synthesis and (6) unidentified cognitive processes implicated in conceptual design elsewhere in the literature.
The asylum process has received a lot of recent media attention but little has been said about the psychological needs of those seeking or granted asylum. Many asylum seekers have experienced trauma and torture, which is associated with substantial psychiatric and psychological morbidity. The Spiritan Asylum Services Initiative (Spirasi) is Ireland’s national treatment centre for survivors of torture. The aim of this study was to examine the demographic profile of those attending Spirasi and to consider potential clinical implications of this.
Methods
We retrospectively analysed demographic data relating to the 2590 individuals who attended Spirasi over a 12-year period (2001–2012 inclusive).
Results
The majority of attenders were asylum seekers (88%), male (71%) and from African countries. The mean age was 31.9 years. The rate of new referrals, as a percentage of Ireland’s asylum-seeking population, has stabilised at ~6% since 2008. Women are underrepresented among those who attend.
Conclusions
The number of new referrals to Spirasi is lower than expected given international estimates of torture prevalence and the impact this has on mental health. Clinicians working with populations of asylum seekers and refugees should sensitively enquire about such events and be aware of the available services. Female refugees and asylum seekers are underrepresented, especially from Asian and Middle Eastern regions. Psychiatric, psychological and general practice services need to respond flexibly to evolving patterns of migration and address potential barriers to access, especially among female refugees and asylum seekers.
