Objective: This meta-analysis aims to estimate the pooled prevalence of mental disorders among COVID-19 survivors.

Methods: The databases Pubmed, Google Scholar, ScienceDirect, and medRxiv have been searched up to 1 August 2021 using COVID-19, survivors, mental disorders, and their related MeSH terms. The included studies were either cross-sectional, cohort, or case-control in design. Those studies included COVID-19 survivors after 14 or more days from their COVID-19 recovery and used validated questionnaires to assess their mental health outcomes. The random-effects model was used to pool the data from the incorporated studies. The heterogeneity was assessed using Cochran's Q heterogeneity test and I² statistic.

Results: Twenty-seven studies were included in the data synthesis with a total sample size of 9605 COVID-19 survivors. The prevalence rates for Post-Traumatic Stress Disorder (PTSD), anxiety, psychological distress, depression, and sleeping disorders were 20% (95% CI = 16-24%), 22% (95% CI = 18-27%), 36% (95% CI = 22-51%), 21% (95% CI = 16-28%), and 35% (95% CI = 29-41%), respectively.

Conclusions: Although we found high heterogeneity across the included studies, our meta-analysis provides evidence that there are psychological sequelae in COVID-19 survivors that require medical assiduity as well as further research on the matter.KEY POINTSIncreased prevalence of psychological sequelae among COVID-19 survivors.The prevalence of PTSD was 20% (95% CI = 16-24%) and of anxiety was 22% (95% CI = 18-27%) among COVID-19 survivors.The prevalence of psychological distress was 36% (95% CI = 22-51%), of depression was 21% (95% CI = 16-28%), and of sleep disorders was 35% (95% CI = 29-41%) among COVID-19 survivors.Future researches are recommended to search for effective and safe methods to mitigate the psychological sequelae in COVID-19 patients.

Objectives: There is a paucity of research about psychiatric inpatients' experience of dignity. Most of the limited literature on this topic is qualitative. Our study provides quantitative data about self-rated dignity among involuntary and voluntary psychiatry inpatients. We explore relationships between perceived dignity and legal status, coercion, level of insight, diagnosis, and therapeutic alliance, among other parameters.

Methods: We recruited 107 participants aged 18 years or over from two inpatient psychiatric units in Dublin, Ireland over a 30-month period. Interviews consisted of structured, validated assessment tools. Demographic and clinical data were obtained from patient charts.

Results: Patient Dignity Inventory (PDI) score was non-normally distributed (skewed to the right), with a median score of 63.0 out of 125 (inter-quartile range: 40.0-80.0). On multi-variable testing, lower self-rated dignity was associated with higher perceived coercion, better insight and more negative symptoms. There was no association between dignity and gender, employment status, marital status, ethnicity, age, admission status, diagnosis, working alliance, positive symptoms or cognition.

Conclusions: Lack of dignity is linked with perceived coercion and negative symptoms, and is seen in patients with better insight. These links merit further study if we are to understand patient dignity in a more nuanced and useful way.KEYPOINTSWe interviewed psychiatric inpatients using the Patient Dignity Inventory and other structured assessment tools.There was no significant difference between voluntary and involuntary patient groups' self-rated dignity.Less self-rated dignity was seen in patients with higher levels of perceived coercion.Patients with better insight reported lower dignity.Dignity scores were not significantly associated with age, gender, ethnicity, diagnosis or length of stay in hospital.

Background: Previous studies have explored associations between Tumour Necrosis factor-Alpha (TNF-a) polymorphisms and Schizophrenia. Their results were controversial. We conducted a meta-analysis to clarify the association between TNF-a - 308 G/A(rs1800629), -1031T/C(rs1799964), -863C/A(rs1800630) and -857 C/T (rs1799724) polymorphisms and Schizophrenia.

Methods: All the studies that investigated the association between TNF-a polymorphisms and Schizophrenia published before 15 October 2020 were included in. The literature were comprehensively searched and identified in 2 English databases and 2 Chinese databases. The odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated.

Results: For -1031 T/C polymorphism, at the overall analysis, significantly decreased Schizophrenia risk was found in T allele in the allele model (p = 0.006, OR = 0.88) and increased Schizophrenia risk was found in TC + CC genotype in the dominant model (p = 0.005, OR = 1.17). Similarly, the same results were obtained when pooled analyses were included in high-quality studies (allele model: p = 0.005, OR = 0.86; dominant model: p = 0.007, OR = 1.20). In addition, when stratified by ethnicity, the results showed that in allele model, the T allele decreased Schizophrenia risk in East Asian (p = 0.031, OR = 0.90).

Conclusion: The association may most likely result from less-credible, rather than from true associations or biological factors on the TNF-a - 1031 T/C polymorphism with Schizophrenia risk.KeypointsFor -1031T/C polymorphism, at the overall analysis, significantly decreased schizophrenia risk was found in T allele in the allele model, and increased schizophrenia risk was found in TC + CC genotype in the dominant model.In allele model, the T allele decreased schizophrenia risk in East Asian when stratified by ethnicity, and in the dominant model, TC + CC genotype increased schizophrenia risk in East Asian.

Background: Mental capacity for treatment decisions in psychiatry inpatients is an important ethical and legal concern, especially in light of changes in mental capacity legislation in many jurisdictions.

Aims: To conduct a systematic review of literature examining the prevalence of mental capacity for treatment decisions among voluntary and involuntary psychiatry inpatients, and to assess any correlations between research tools used to measure mental capacity and binary judgements using criteria such as those in capacity legislation.

Method: We searched PsycINFO, Ovid MEDLINE and EMBASE for studies assessing mental capacity for treatment decisions in people admitted voluntarily and involuntarily to psychiatric hospitals.

Results: Forty-five papers emanating from 33 studies were identified. There was huge variability in study methods and often selective populations, but the prevalence of decision-making capacity varied between 5% and 83.7%. These figures resulted from studies using cut-off scores or categorical criteria only. The prevalence of decision-making capacity among involuntary patients ranged from 7.7% to 42%, and among voluntary patients ranged from 29% to 97.9%. Two papers showed positive correlations between clinicians' judgement of decision-making capacity and scores on the MacArthur Competence Assessment Tool for Treatment; two papers showed no such correlation.

Conclusions: Not all voluntary psychiatry inpatients possess mental capacity and many involuntary patients do. This paradox needs to be clarified and resolved in mental health legislation; supported decision-making can help with this task.Key PointsLegislative changes for mental capacity are taking place in many jurisdictions.This is an important human rights issue for many people, including psychiatry inpatients.In our review, we found the prevalence of decision-making capacity varies between 5% and 83.7% in psychiatry inpatients.Not all voluntary inpatients have decision-making capacity.Many involuntary inpatients have mental capacity to make decisions.Supported decision-making can help those with impairments in their mental capacity.

Background: Few studies have investigated the relationship between electroconvulsive therapy (ECT) and markers of nitrosative stress and oxidative DNA damage.

Objective: The aim of this study is to examine changes in nitrosative stress and oxidative DNA damage in patients with a depressive episode treated with ECT.

Methods: The current study included 48 patients with a depressive episode treated with ECT and 30 healthy control participants. First, the serum nitrosative stress markers of nitric oxide (NO•), nitric oxide synthase (NOS), and peroxynitrite (ONOO-) and the oxidative DNA damage marker 8-hydroxy-2'-deoxyguanosine (8-OHdG) were compared between the study and control groups. These parameters were also compared pre- and post-treatment for the study group.

Results: NO•, NOS, and ONOO- levels were significantly higher in patients with depressive disorder (DD) than in the control group. NO• and NOS levels significantly decreased in the ECT group after treatment while 8-OHdG levels significantly increased.

Conclusions: The study findings suggest that ECT may have reduced nitrosative stress levels while increasing oxidative DNA damage. More research is now needed to better understand the issue.KEY POINTSNitrosative stress levels can increase in patients with depressive disorder.Electroconvulsive therapy may reduce nitrosative stress while increasıng oxidative DNA damage.These results suggest that nitrosative stress plays an important role in the mechanism of action of electroconvulsive therapy.

Introduction: Confabulations refer to the emergence of memories of experiences and events that are incorrect in place and time, or never took place. In alcoholic Korsakoff's syndrome, confabulations have been frequently reported, but seldomly been investigated. Traditional reports on confabulations state that confabulations in KS mainly occur in the post-acute phase of the illness. The aim of the study was to investigate whether confabulations extinguish in KS.

Methods: An observational rating of confabulation behaviour (the NVCL-R) was completed for 172 KS patients with alcoholic KS. Post-acute and chronic KS patients were compared cross-sectionally in two centres.

Results: Provoked and spontaneous confabulations were present in post-acute and chronic patients. Patients residing in a long-term care facility more often presented themselves with spontaneous confabulations than patients in a diagnostic centre.

Conclusions: In contrast to the traditional view, confabulations may be present throughout the course of KS, and are possibly more frequently present in patients receiving care in specialised long-term care facilities than in patients who receive less intensive support.Key pointsConfabulations are a central characteristic of Korsakoff's syndromeIn contrast to popular belief, confabulations may be present in acute and chronic Korsakoff's syndromeThe severity of confabulations is related to an unfavourable disease outcome in KSA longitudinal approach would help the confirmation of finding no decline in confabulations over time.

Background: The mental health (MH) burden on healthcare practitioners (HCPs) is emerging as a significant cost of the pandemic, although few studies have compared the MH of HCPs in different countries.

Methods: A link to an online survey was posted in the Spring of 2020 which included questions regarding perceived impact of the pandemic; current MH symptom severity and impairment was evaluated using validated scales.

Results: Overall, 1315 individuals (74% female, mean age: 42.9 + 16.4) in Canada, the United States, Brazil and Italy completed the survey. Nearly 26% met diagnostic thresholds for GAD and MDD; Italian respondents reported the lowest rates of disorder. Except for Canada, non-HCPs in each country reported higher symptom severity than HCPs. Amongst the HCPs, Canadian HCPs reported the highest rates of anxiety and depression as well as increases in alcohol and cannabis use, lower levels of perceived emotional support and more worry about themselves or their loved ones contracting COVID-19.

Conclusion: Despite key infrastructural and COVID-19 mortality differences between the countries, the MH effects appeared to be quite similar. HCPs, with the exception of Canada, reported less impact on their mental health compared to the general population, suggesting resilience in the face of adversity.Key pointsRates of current mental health disorders were similar across Canada, the USA and Brazil but lower in Italy, yet much higher than pre-pandemic ratesNon-Healthcare Practitioners (HCPs) reported significantly higher severity on all MH scales in the overall sample. This was consistent within the USA, Brazil and Italy, however in Canada, HCPs reported higher anxiety, depression and stress symptom severity compared to Canadian non-HCPs.Canadian HCPs reported significantly higher anxiety and depression symptom severity than all other countriesCanadian HCPs also reported significantly greater increases in alcohol and cannabis use, lower levels of perceived emotional support and more worry about themselves or their loved ones contracting COVID-19 compared to HCPs in the other countries.

Objective: To assess the long-term impact of early COVID-19 lockdown phase on emergency psychiatric consultations in two psychiatric emergency departments located in Italy.

Methods: We conducted a cross-sectional study comparing the number and characteristics of emergency psychiatric consultations during post-lockdown with respect to the lockdown period. Sociodemographic data, clinical characteristics, referred symptoms, diagnosis, information on multiple psychiatric consultations and hospitalisation were collected.

Results: A rise of almost 60% in emergency psychiatric consultations during the post-lockdown compared to the lockdown period was observed. Emergency psychiatric consultations in the post-lockdown period were associated with lower rates of cannabis (aOR = 0.42, p = 0.011) and cocaine use (aOR = 0.39, p = 0.011). Despite a lower occurrence of two or more psychiatric consultations was observed during post-lockdown phase (aOR = 0.44, p = 0.008), subjects who had anxiety disorders (aOR = 3.91, p = 0.000) and substance intoxication or withdrawal (aOR = 6.89, p = 0.000) were more likely to present to emergency psychiatric consultations during post-lockdown period compared to the lockdown one.

Conclusions: Substance intoxication or withdrawal and anxiety disorders increased after the COVID-19 lockdown. The findings of this study suggest to address more economic and professional sources to the mental health areas potentially more affected by the different phases of a pandemic.KEYPOINTSCOVID-19 pandemic and lockdown measures increased mental health unmet needs.According to our findings, a rise in emergency psychiatric consultations during the post-lockdown compared to the lockdown period was observed.Patients with substance intoxication or withdrawal syndrome and anxiety disorders were significantly more likely to present to emergency psychiatric consultations during post-lockdown.Lockdown was associated with higher rates of both cannabis and cocaine use disorders as well as of multiple psychiatric consultations.Alternative strategies to improve mental health such as e-health technologies should be promoted.
