To compare psychiatric emergencies and self-harm at emergency departments (EDs) 1 year into the pandemic, to early pandemic and pre-pandemic, and to examine the changes in the characteristics of self-harm presentations. This retrospective cohort study expanded on the Pandemic-Related Emergency Psychiatric Presentations (PREP-kids) study. Routine record data in March to April of 2019, 2020, and 2021 from 62 EDs in 25 countries were included. ED presentations made by children and adolescents for any mental health reasons were analyzed. Altogether, 8,174 psychiatric presentations were recorded (63.5% female; mean [SD] age, 14.3 [2.6] years), 3,742 of which were self-harm presentations. Rate of psychiatric ED presentations in March to April 2021 was twice as high as in March to April 2020 (incidence rate ratio [IRR], 1.93; 95% CI, 1.60-2.33), and 50% higher than in March to April 2019 (IRR, 1.51; 95% CI, 1.25-1.81). Rate of self-harm presentations doubled between March to April 2020 and March to April 2021 (IRR, 1.98; 95% CI, 1.68-2.34), and was overall 1.7 times higher than in March to April 2019 (IRR, 1.70; 95% CI, 1.44-2.00). Comparing self-harm characteristics in March to April 2021 with March to April 2019, self-harm contributed to a higher proportion of all psychiatric presentations (odds ratio [OR], 1.30; 95% CI, 1.05-1.62), whereas female representation in self-harm presentations doubled (OR, 1.98; 95% CI, 1.45-2.72) and follow-up appointments were offered 4 times as often (OR, 4.46; 95% CI, 2.32-8.58). Increased pediatric ED visits for both self-harm and psychiatric reasons were observed, suggesting potential deterioration in child mental health. Self-harm in girls possibly increased and needs to be prioritized. Clinical services should continue using follow-up appointments to support discharge from EDs.

Suicide is a public health issue, and there are several factors leading to suicide, like mental illness and psychosocial stressors. Actual loneliness (living alone) and subjective loneliness (feeling of being alone) and different suicidal behaviors have been reported to have some link. This scoping review aimed to assess the association between loneliness and suicidal behaviour by exploring the existing literature. A scoping review was conducted implementing the appropriate framework and in accord with the PRISMA-ScR extension. A PubMed database search was made using a combination of terms to find publications in English from 2011 to 2021. Studies were included if they reported quantitative outcomes of the association between loneliness and suicidal experiences, including suicidal thoughts, plans, and/or attempts. Screening and data charting of the published literature was conducted by a panel of authors. The accuracy and clarity of extracted data was checked by three reviewers. Among 421 articles found, 31 full texts were evaluated based on exclusion and inclusion criteria, out of which, 18 papers that reported quantitative outcomes of the association between loneliness and suicidal experiences were included. We found that association between loneliness and suicidal behaviour is determined by individual, social and cultural factors. Co-existing mental illness, substance use disorder and economic hardship play an important role for the completion of suicide. Loneliness is correlated with suicide, and the knowledge about this association could assist in the identification of suicidal individuals or those at elevated risk of suicidal behaviour. Future studies should focus on loneliness and its relation to suicidal ideation in individuals with different mental health disorders and personalities.

Adolescence is a sensitive phase of human development where individuals, aged 10–19 years, are particularly vulnerable to developing mental health problems (MHPs). South Asia, home to 24% of the world's population, is mostly comprised of low- and middle-income countries (LMIC). Most of the world's young people live in LMICs. This systematic review aims to assess the available evidence on the nature, prevalence and determinants of MHPs experienced by adolescents in south Asia. Following PRISMA guidelines, searches were conducted in four online databases (Ovid Medline, Ovid EMBASE, Ovid Global Health, Ovid PsycInfo), titles, abstracts, and full-texts were screened, data extracted and quality assessed. Extracted data were categorised into school-based studies (SBS) and non-school-based studies (NSBS). Data were further stratified according to country, MHPs and narratively synthesised. Of the 5847 records identified in the searches, 117 met inclusion criteria. Most (n = 87) were SBS. Key MHPs reported across countries include anxiety disorders and depression. Wide ranges of prevalence rates were reported for anxiety in Indian SBS (1.5–81.6%) and NSBS (1.8–88.1%), and for depression, Pakistani SBS (21–79%) and Indian NSBS (0.4–98.5%). Determinants include individual characteristics; violent victimisation; poor family/home/school environment/peer relationships; already experiencing MHPs and substance use/abuse. Increased physical activity, adequate nutrition, safe/positive homes/family environment, being unmarried females, higher maternal education, peer support/friendship, higher education level and engaging in extra-curricular activities were protective of mental well-being. Prevalence of MHPs among south Asian adolescents appears high. Determinants include social, cultural, environmental and socioeconomic factors often beyond individual control. Mental health policies and programs and research appropriate to the cultural context, that address social determinants of MHPs and evidence gaps, are needed to tackle the significant mental health burden among south Asian adolescents.

Sri Lanka's civil war and the tsunami in 2004 had enormous psychological impacts on the country's children. Tackling these issues has been difficult due to the lack of specialists in child and adolescent psychiatry. The end of the war in 2009 opened new avenues for the development of mental health services for children and youth in Sri Lanka. The year 2016 was historic in that the first board-certified child and adolescent psychiatrists assumed services in the country, after training in Australia.

Although the physical consequences of dengue are well documented, delayed psychological co-morbidities are not well studied to date. Therefore, the objective of the present study was to determine the prevalence of depressive, anxiety and stress symptoms among past dengue patients. A community-based, case–control study in a multi-ethnic urban setting was conducted in Sri Lanka involving adults who were diagnosed to have dengue fever by a positive dengue IgM antibody response between 6 and 24 months ago. Self-administered Depression, Anxiety and Stress Scale (DASS-21), Centre for Epidemiological Studies Depression Scale (CESD-20) and a structured clinical interview by a psychiatrist were done in the patients and in an age and gender-matched control group. Fifty-three participants each in the patient (mean age 42.9 years, SD 15.5) and control (mean age 41.6 years, SD 15.3) groups were surveyed. The ages ranged from 18 to 70 years and 64.2% were females. The majority (90.6%; n = 48) of the individuals had been diagnosed with dengue fever followed by dengue haemorrhagic fever (9.4% n = 5). Dengue patients had higher DASS-21 mean depressive scores (means 11.7/9.4, SD 6.4/4.0, t = 2.2, p = .028), anxiety scores (means 10.7/7.2, SD 6.8/1.8, t = 3.6, p = .0005), stress scores (means 12.0/8.8, SD 5.3/3.5, t = 3.6, p = .0004) and CESD-20 scores (means 16.1/11.7, SD 9.4/7.3, t = 2.6, p = .008) than controls. The DSM-5 depressive disorder was clinically detected by the psychiatrist among 15.1 and 7.5% in patient and control groups (OR 2.1; CI .5–7.7; p = .22). Limitations: a limitation is the small sample size. Patients with past dengue had significantly higher depressive, anxiety and stress symptoms than the control group according to the DASS-21 and CESD-20 tools. To our knowledge, this is the first report on delayed psychological morbidity related to dengue. This may warrant healthcare professionals to incorporate mental counselling for dengue patients.
