Background: The outbreak of coronavirus disease 19 (CO-VID-19) has led to measures of social distancing and quarantine worldwide. This stressful period may lead to psychological problems, including increases in substance use. Objective: To investigate changes in alcohol, tobacco, and cannabis consumption before and during COVID-19 lockdown and motives for these changes in substance use. Method: A web-based survey was filled out by an unselected population during the social distancing measures of the CO-VID-19 pandemic in Belgium that assessed changes in alcohol, tobacco, and cannabis consumption in the period before and during the COVID-19 lockdown and also asked about reasons for change. Results: A total of 3,632 respondents (mean age 42.1 ± 14.6 years; 70% female) filled out the survey. Overall, respondents reported consuming more alcohol (d = 0.21) and smoking more cigarettes (d = 0.13) than before the COVID-19 pandemic (both p < 0.001), while no significant changes in the consumption of cannabis were noted. The odds of consuming more alcohol during the lock-down were associated with younger age (OR = 0.981, p < 0.001), more children at home (OR = 1.220, p < 0.001), nonhealthcare workers (p < 0.001), and being technically unemployed related to COVID-19 (p = 0.037). The odds of smoking more cigarettes during the lockdown were associated with younger age (OR = 0.988, p = 0.027), current living situation (p < 0.001), lower education (p = 0.015), and working situation related to COVID-19 (p = 0.018). Boredom, lack of social contacts, loss of daily structure, reward after a hard-working day, loneliness, and conviviality were the main reasons for consuming more of the various substances. Conclusions: During the lockdown, individuals consumed slightly more alcohol and smoked marginally more cigarettes compared to the period before the lockdown. Further research focussing on follow-up of individuals at risk may be useful to provide appropriate care in post-COVID times.

ECT is particularly effective in patients with depression with psychotic features and in elderly people with depression. More research on both biological and clinical predictors is needed to further evaluate the position of ECT in treatment protocols for major depression. Declaration of interest None.

BackgroundSub-Saharan transmigrants in Morocco are extremely vulnerable to sexual violence. From a public health perspective, the healthcare system is globally considered an important partner in the prevention of sexual violence. The aim of this study is twofold. In a first phase, we aimed to identify the current role and position of the Moroccan healthcare sector in the prevention of sexual violence against sub-Saharan transmigrants. In a second phase, we wanted these results and available guidelines to be the topic of a participatory process with local stakeholders in order to formulate recommendations for a more desirable prevention of sexual violence against sub-Saharan transmigrants by the Moroccan healthcare sector.MethodsKnowledge, attitudes and practices of healthcare workers in Morocco concerning sexual violence against sub-Saharan transmigrants and its prevention were firstly explored in semi-structured interviews after which they were discussed in a participatory process resulting in the formulation of recommendations.ResultsAll participants (n=24) acknowledged the need for desirable prevention of sexual violence against transmigrants. Furthermore, important barriers in tertiary prevention practices, i.e. psychosocial and judicial referral and long-term follow-up, and in secondary prevention attitudes, i.e. active identification of victims were identified. Moreover, existing services for Moroccan victims of sexual violence currently do not address the sub-Saharan population. Thus, transmigrants are bound to rely on the aid of civil society.ConclusionsThis research demonstrates the low accessibility of existing Moroccan services for sub-Saharan migrants. In particular, there is an absence of prevention initiatives addressing sexual violence against the sub-Saharan transmigrant population. Although healthcare workers do wish to develop prevention initiatives, they are dealing with structural difficulties and a lack of expertise. Recommendations adapted to the context of sub-Saharan transmigrants in Morocco are suggested.

Background: A mild pro-inflammatory status accompanies bipolar disorder (BD). Inflammation can cause a shift in monoamine metabolism, thereby activating more cytotoxic pathways. The extent to which low-grade inflammation in BD interacts with monoamine metabolism and how this accords to aging and clinical course is unknown.Objectives: We evaluated the presence of alterations in inflammation and monoamine metabolism in BD throughout different mood states and the role of aging therein.Methods: Sixty-seven patients with BD were included during an acute mood episode, either depressive (n = 29), (hypo)manic (n = 29), or mixed (n = 9). Plasma levels of inflammatory markers [tumor necrosis factor alpha (TNF-α), interferon gamma (IFN-y), interleukin-6 (IL-6), and C-reactive protein (CRP)] and markers of monoamine metabolism (neopterin, tryptophan, kynurenine, phenylalanine, and tyrosine) were measured repeatedly during a follow-up of 8 months. Levels in patients were compared to controls (n = 35) and correlated to HDRS-17 and YMRS scores. Spearman correlations and linear mixed model analysis were used for statistical analysis.Results: Forty-nine patients and 30 controls (age range: 22–62 years) completed the study. No significant differences in inflammatory markers were found between patients and controls overall. Tryptophan, tyrosine, and phenylalanine levels were lower in patients. In both patients and controls, markers of inflammation correlated only weakly with markers of monoamine metabolism, but correlations representative for activity of cytotoxic pathways in monoamine metabolism were more pronounced in patients. In patients, but not in controls, older age was associated with increases in inflammatory markers (IL-6, CRP, neopterin) and the kynurenine/tryptophan ratio. None of the biological markers correlated significantly with mood symptom severity.Conclusion: Our data suggest an increased susceptibility of patients with BD to develop a pro-inflammatory state and to shift monoamine metabolism toward more cytotoxic pathways. These findings are in support of the theory of neuroprogression and accelerated aging in BD. Since associations between biological markers and clinical characteristics are limited, it remains to be determined if alterations in biological markers are due to a disease effect or rather are a consequence of confounding factors.

Background In psychotic and mood disorders, immune alterations are hypothesized to underlie cognitive symptoms, as they have been associated with elevated blood levels of inflammatory cytokines, kynurenine metabolites, and markers of microglial activation. The current meta-analysis synthesizes all available clinical evidence on the associations between immunomarkers (IMs) and cognition in these psychiatric illnesses. Methods Pubmed, Web of Science, and Psycinfo were searched for peer-reviewed studies on schizophrenia spectrum disorder (SZ), bipolar disorder (BD), or major depressive disorder (MDD) including an association analysis between at least one baseline neuropsychological outcome measure (NP) and one IM (PROSPERO ID:CRD42021278371). Quality assessment was performed using BIOCROSS. Correlation meta-analyses, and random effect models, were conducted in Comprehensive Meta-Analysis version 3 investigating the association between eight cognitive domains and pro-inflammatory and anti-inflammatory indices (PII and AII) as well as individual IM. Results Seventy-five studies (n = 29,104) revealed global cognitive performance (GCP) to be very weakly associated to PII (r = −0.076; p = 0.003; I2 = 77.4) or AII (r = 0.067; p = 0.334; I2 = 38.0) in the combined patient sample. Very weak associations between blood–based immune markers and global or domain-specific GCP were found, either combined or stratified by diagnostic subgroup (GCP x PII: SZ: r = −0.036, p = 0.370, I2 = 70.4; BD: r = −0.095, p = 0.013, I2 = 44.0; MDD: r = −0.133, p = 0.040, I2 = 83.5). We found evidence of publication bias. Discussion There is evidence of only a weak association between blood-based immune markers and cognition in mood and psychotic disorders. Significant publication and reporting biases were observed and most likely underlie the inflation of such associations in individual studies.

Objectives Cytokines are thought to contribute to the pathogenesis of psychiatric symptoms by kynurenine pathway activation. Kynurenine metabolites affect neurotransmission and can cause neurotoxicity. We measured inflammatory markers in patients with bipolar disorder (BD) and studied their relation to kynurenine metabolites and mood. Methods Patients with BD suffering from an acute mood episode were assigned to the depressive (n = 35) or (hypo)manic (n = 32) subgroup. Plasma levels of inflammatory markers [cytokines, C‐reactive protein] and kynurenine metabolites [tryptophan (TRP), kynurenine (KYN), 3‐hydroxykynurenine (3‐HK), quinolinic acid (QA), kynurenic acid (KYNA)] were measured on 6 time points during 8 months follow‐up. Biological marker levels in patients were compared to controls (n = 35) and correlated to scores on mood scales. Spearman correlations and linear mixed models were used for statistical analysis. Results Twenty patients of the manic subgroup, 29 of the depressive subgroup, and 30 controls completed the study. The manic subgroup had a rapid remission of mood symptoms, but in the depressive subgroup subsyndromal symptoms persisted. No differences in inflammation were found between groups. A strong correlation between tumor necrosis factor‐α and KYN, KYN/TRP, 3‐HK and QA (ρ > 0.60) was specific for the manic group, but only at baseline (during mania). The depressive subgroup had a lower neuroprotective ratio (KYNA/3‐HK, P = .0004) and a strong association between interferon‐y and kynurenine pathway activation (P < .0001). KYNA was low in both patient groups versus controls throughout the whole follow‐up (P = .0008). Conclusions Mania and chronic depressive symptoms in BD are accompanied by a strong interaction between inflammation and a potentially neurotoxic kynurenine metabolism.
