To estimate the prevalence of DSM-V mental disorders in a population of Irish emerging adults

Mental disorders are the leading cause of years lived with disability in youth worldwide. Few studies use gold standard of face to face semi-structured standardized interview tools, and this is a limitation in the estimates of prevalence rates of mental disorder in the extant literature.

Briefly, we recruited a representative sample of 212 adolescents and followed them up over ten years. In this wave of the adolescent brain development study, 103 of the initial 212 participants took part, 50 males and 53 females, with a mean age of 20.87 years (SD = 1.3). Psychopathology was assessed in all participants by trained research psychologists and mental health professionals using the Structured Clinical Interview for DSM-V (SCID).

52.4% of participants had one lifetime mental disorder, the prevalence rates were highest for Major Depressive Episode (25.3%), Social Anxiety (12.6%) and Generalized Anxiety (8.7%). 50.5% had a history of a mental disorder. 27.2% had 1 lifetime diagnosis, 15.5% had 2 and 7.8% had >2.

Rates of mental disorder rapidly increase during emerging adulthood. In a similar Irish study, 55% of young adults met the criteria for lifetime mental disorder. Whilst the rates of mental disorder are high in young people, previous longitudinal research has suggested that many common mental disorders remit by the late twenties. We suggest a need for further research investigating the comparative later functional and economic outcomes of these young people. Research to date is supportive of a need to expand capacity of youth friendly services for prevention and treatment.

Ethical Approval

Ethical approval for the study protocols, including interviews and assessments, along with informed consent documents, was granted by the Beaumont Hospital Medical Ethics Committee in 2016.

The COVID-19 pandemic has created a high demand on personal protective equipment, including disposable N95 masks. Given the need for mask reuse, we tested the feasibility of vaporized hydrogen peroxide (VHP), ultraviolet light (UV), and ethanol decontamination strategies on N95 mask integrity and the ability to remove the infectious potential of SARS-CoV-2.

Disposable N95 masks, including medical grade (1860, 1870+) and industrial grade (8511) masks, were treated by VHP, UV, and ethanol decontamination. Mask degradation was tested using a quantitative respirator fit testing. Pooled clinical samples of SARS-CoV-2 were applied to mask samples, treated, and then either sent immediately for real-time reverse transcriptase–polymerase chain reaction (RT-PCR) or incubated with Vero E6 cells to assess for virucidal effect.

Both ethanol and UV decontamination showed functional degradation to different degrees while VHP treatment showed no significant change after two treatments. We also report a single SARS-CoV-2 virucidal experiment using Vero E6 cell infection in which only ethanol treatment eliminated detectable SARS-CoV-2 RNA.

We hope our data will guide further research for evidenced-based decisions for disposable N95 mask reuse and help protect caregivers from SARS-CoV-2 and other pathogens.

Psychotic experiences (PE) are highly prevalent in childhood and are known to be associated with co-morbid mental health disorders and functional difficulties in adolescence. However, little is known about the long-term outcomes of young people who report PE.

As part of the Adolescent Brain Development Study, 211 young people were recruited in childhood (mean age 11.7 years) and underwent detailed clinical interviews, with 25% reporting PE. A 10 year follow-up study was completed and 103 participants returned (mean age 20.9 years). Structured clinical interviews for DSM-5 (SCID-5) and interviewer-rated assessments of functioning were conducted. A detailed neuropsychological battery was also administered. Analyses investigated group differences between those who had ever reported PE and controls in early adulthood.

The PE group was at a significantly higher risk of meeting DSM-5 criteria for a current (OR 4.08, CI 1.16–14.29, p = 0.03) and lifetime psychiatric disorder (OR 3.27, CI 1.43–7.47, p = 0.005). They were also at a significantly higher risk of multi-morbid lifetime psychiatric disorders. Significantly lower scores on current social and global functioning measures were observed for the PE group. Overall, there were no differences in neuropsychological performance between groups apart from significantly lower scores on the Stroop Word task and the Purdue Pegboard task for the PE group.

Our findings suggest that reports of PE are associated with poorer mental health and functional outcomes in early adulthood, with some persisting cognitive and motor deficits. Young people who report such symptoms could be considered a target group for interventions to aid functional outcomes.

Candida auris (CA) is an emerging multidrug-resistant pathogen associated with increased mortality. The environment may play a role, but transmission dynamics remain poorly understood. We sought to limit environmental and patient CA contamination following a sustained unsuspected exposure.

The index case patient and 17 collocated ward mates.

Immediately after confirmation of CA in the bloodstream and urine of a patient admitted 6 days previously, active surveillance, enhanced transmission-based precautions, environmental cleaning with peracetic acid-hydrogen peroxide and ultraviolet light, and patient relocation were undertaken. Pre-existing agreements and foundational relationships among internal multidisciplinary teams and external partners were leveraged to bolster detection and mitigation efforts and to provide genomic epidemiology.

Candida auris was isolated from 3 of 132 surface samples on days 8, 9, and 15 of ward occupancy, and from no patient samples (0 of 48). Environmental and patient isolates were genetically identical (4–8 single-nucleotide polymorphisms [SNPs]) and most closely related to the 2013 India CA-6684 strain (~200 SNPs), supporting the epidemiological hypothesis that the source of environmental contamination was the index case patient, who probably acquired the South Asian strain from another New York hospital. All isolates contained a mutation associated with azole resistance (K163R) found in the India 2105 VPCI strain but not in CA-6684. The index patient remained colonized until death. No surfaces were CA-positive 1 month later.

Compared to previous descriptions, CA dissemination was minimal. Immediate access to rapid CA diagnostics facilitates early containment strategies and outbreak investigations.

The purpose was to examine the associations among body weight status, blood pressure and daily Na intake among grade 7 students from south-western Ontario, Canada.

Cross-sectional. Data were collected using the Food Behaviour Questionnaire, including a 24 h diet recall. Measured height and weight were used to determine BMI. Blood pressure was taken manually using mercury sphygmomanometers.

Twenty-six schools in south-western Ontario, Canada.

Grade 7 students (n 1068).

Body weight status indicated 1 % were underweight, 56 % normal weight, 23 % overweight and 20 % were obese. Mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 108·3 (sd 10·3) mmHg and 66·0 (sd 7·5) mmHg, respectively, and mean Na intake was 2799 (sd 1539) mg/d. Bivariate analyses suggested that SBP (P < 0·001) and DBP (P < 0·001) were significantly different by body weight status, yet no associations were observed for Na. Adjusted for gender, ethnicity and under-reporting, participants were more likely to be overweight/obese if they had higher SBP (v. lower: OR = 1·06, 95 % CI 1·05, 1·08, P < 0·001), higher DBP (v. lower: OR = 1·02, 95 % CI 1·00, 1·04, P = 0·043) and higher intakes of Na (3rd v. 1st quartile: OR = 1·72, 95 % CI 1·14, 2·59, P = 0·009; 4th v. 1st quartile: OR = 2·88, 95 % CI, 1·76, 4·73, P < 0·001).

High intakes of Na, coupled with high SBP and DBP, were associated with overweight and obesity status among the grade 7 sample from south-western Ontario, Canada.
