Substance use and self-harm emergency department presentations during COVID19: evidence from a National Clinical Programme for Self-Harm

INTRODUCTION

Given the evidence that drinking patterns and self-harm hospital presentations have changed during COVID-19, this study aimed to examine any change in self-harm and suicide-related ideation presentations, together with any possible contribution made by alcohol or substance misuse, to Irish Emergency Departments in 2020, compared with 2018 and 2019.

METHODS

A population-based cohort with self-harm and suicide-related ideation presenting to Irish hospitals derived from the National Clinical Programme for Self-Harm was analysed. Descriptive analyses were conducted based on sociodemographic variables and types of presentation for the period January to August 2020 and compared with the same period in 2018 and 2019. Binomial regression analyses were performed to investigate the independent effect of demographic characteristics and pre/during COVID-19 periods on the use of substances as contributory factors in the self-harm and suicide-related ideation presentations.

RESULTS

12,075 presentations due to self-harm and suicide-related ideation were recorded for the periods January-August 2018-2020 across nine emergency departments. The COVID-19 year was significantly associated with substances contributing to self-harm and suicide-related ideation ED presentations (OR = 1.183; 95% CI, 1.075-1.301, p < 0.001). No changes in the demographic characteristics were found for those with self-harm or suicide-related ideation across the years. Suicide-related ideation seemed to be increased after May 2020 compared with previous years. In terms of self-harm episodes with comorbid drug and alcohol overdose and poisoning, these were significantly increased in January-August 2020, compared with previous timepoints (χ2 = 42.424, df = 6, p < 0.001).

CONCLUSION

An increase in suicide-related ideation and substance-related self-harm presentations may indicate longer term effects of the pandemic and its relevant restrictions. Future studies might explore whether those presenting with ideation will develop a risk of suicide in post-pandemic periods.

Irish Psychiatric Association survey of psychiatric services in Ireland

Aims and Method

The Irish Psychiatric Association conducted a national survey of psychiatric services in Ireland to examine clinical resources in relation to the relative affluence of catchment areas. A consultant psychiatrist from each catchment area was sent a postal survey form (August 2002) and the data received were cross-referenced with measures of relative affluence.

Results

There was a 72% response rate. A negative relationship emerged between indices of need and both the number of acute beds and the number of consultant psychiatrists per head of the population.

Clinical Implications

The results of this survey indicate that clinical resources in mental health in Ireland are not concentrated in areas of greatest need, but paradoxically have been best developed in areas of greatest affluence.

Genetic variation in DNMT3B and increased global DNA methylation is associated with suicide attempts in psychiatric patients

Recently, a significant epigenetic component in the pathology of suicide has been realized. Here we investigate candidate functional SNPs in epigenetic-regulatory genes, DNMT1 and DNMT3B, for association with suicide attempt (SA) among patients with co-existing psychiatric illness. In addition, global DNA methylation levels [5-methyl cytosine (5-mC%)] between SA and psychiatric controls were quantified using the Methylflash Methylated DNA Quantification Kit. DNA was obtained from blood of 79 suicide attempters and 80 non-attempters, assessed for DSM-IV Axis I disorders. Functional SNPs were selected for each gene (DNMT1; n = 7, DNMT3B; n = 10), and genotyped. A SNP (rs2424932) residing in the 3' UTR of the DNMT3B gene was associated with SA compared with a non-attempter control group (P = 0.001; Chi-squared test, Bonferroni adjusted P value = 0.02). Moreover, haplotype analysis identified a DNMT3B haplotype which differed between cases and controls, however this association did not hold after Bonferroni correction (P = 0.01, Bonferroni adjusted P value = 0.56). Global methylation analysis showed that psychiatric patients with a history of SA had significantly higher levels of global DNA methylation compared with controls (P = 0.018, Student's t-test). In conclusion, this is the first report investigating polymorphisms in DNMT genes and global DNA methylation quantification in SA risk. Preliminary findings suggest that allelic variability in DNMT3B may be relevant to the underlying diathesis for suicidal acts and our findings support the hypothesis that aberrant DNA methylation profiles may contribute to the biology of suicidal acts. Thus, analysis of global DNA hypermethylation in blood may represent a biomarker for increased SA risk in psychiatric patients.

Effects of psychotherapy in moderately severe COPD: a pilot study

Anxiety is common in the "pink puffer" syndrome associated with chronic obstructive pulmonary disease (COPD). The degree of anxiety correlates well with perceived dyspnoea. This pilot study examines the effect of group psychotherapy on anxiety, exercise tolerance, dyspnoea and quality of life. Ten patients with moderately severe, stable COPD (mean forced expiratory volume in one second (FEV1)-1.15 L) had six 90 min sessions of cognitive and behavioural psychotherapy at weekly intervals. Patients completed the Hospital Anxiety and Depression Scale (HADS), Medical Research Council Questionnaire (MRCQ) and St George's Respiratory Questionnaires (SGRQ), 1 week before and after therapy. FEV1, forced vital capacity (FVC), slow vital capacity (SVC), blood gas tensions and 6 min walking distance (6MWD) were measured. Eight control patients attended weekly for lung function and 6MWD for 6 weeks, but had no psychotherapy. Mean baseline HADS score was significantly higher in the psychotherapy group (12) than in controls (7), but otherwise there were no differences in lung function, blood gas tensions, 6MWD, or the other questionnaire scores between groups. After treatment, the physiological and psychological parameters where unchanged in both groups with the exception of the mean 6MWD, which had improved in the psychotherapy group only, from 351 to 423 m (p<0.001), an increase of 24%. Three months after treatment, the 6MWD was still 16% above the baseline value (p=0.02). In conclusion, six sessions of cognitive and behavioural psychotherapy produced a sustained improvement in exercise tolerance in a group of 10 anxious patients with severe chronic obstructive pulmonary disease, without any change in anxiety scores on the Hospital Anxiety and Depression Scale. Further studies of more prolonged, intensive psychotherapy would establish whether better symptom and quality of life scores accompany more dramatic increases in exercise tolerance in "pink puffers".

Systemic hypersensitivity reaction to intravesical BCG

BCGosis is a recognised complication of intravesical BCG immunotherapy for superficial bladder carcinoma. We present here a case of granulomatous hepatitis, pneumonitis and probable pericarditis resulting from an hypersensitivity reaction to intravesical BCG.

Gastric acid secretion in chronic renal failure

Contrary to the small amount of published evidence, but in accordance with clinical impression, we have found an increased incidence of peptic ulceration in people with chronic renal failure. Hyperacidic secretion in response to a standard pentagastrin test occurs in patients established on long-term dialysis treatment. The traditional liability of azotaemic patients to peptic ulceration seems not to be decreased by adequate long-term dialysis and indeed may be worsened.
