Psychiatric emergencies during, after, and before the COVID-19 lockdown: what happened to our patients? A naturalistic observational study.

BACKGROUND: Despite concerns on mental health problems related to lockdowns, recent reports revealed a reduction in psychiatric admissions in Emergency Departments (ED) during the lockdown period compared with the previous year in several countries. Most of the existing studies focused on the first lockdown not considering the different phases of the COVID-19 crisis. The present study aimed to analyze differences in ED admission for psychiatric consultation during three different phases of the COVID-19 health crisis in Italy. METHODS: Information on ED admission for psychiatric consultations were retrospectively collected at the ED of the Santo Spirito Hospital in Rome (Italy), and compared between the three periods: the lockdown (March-June 2020) and the post-lockdown period (June 2020-June 2021) compared to the pre-lockdown (January 2019-March 2020). Multinomial logistic regression was used to assess the risk of accessing ED for psychiatric consultation before, during, after the lockdown. RESULTS: Three thousand and eight hundred seventy-one ED psychiatric consultations were collected. A significant reduction of psychiatric consultations in ED during the lockdown period and the post-lockdown (H 762,45; p < 0.001) was documented. Multinomial logistic regression analysis showed that compared to pre-lockdown during the lockdown and post-lockdown patients were more likely to be men (RRR 1.52; 95% CI 1.10-2.12) and more often diagnosed with non-severe mental illnesses (nSMI) (relative risk ratio [RRR] 1.53, 95% CI 1.10-2.15; and 1.72, 95% CI 1.42-2.08); during the lockdown, patients were also more often diagnosed with alcohol/substance abuse (A&S) (RRR 1.70; 95% CI 1.10-2.65). CONCLUSIONS: several changes in the clinical characteristics of psychiatric consultations during and after the lockdown emerged from the present study; nSMI and A&S abuse patients were more likely to present at the ED in the lockdown and post-lockdown periods while SMI patients appeared to be less likely. These may inform clinicians and future preventive strategies among community mental health services.

Linking novelty seeking and harm avoidance personality traits to cerebellar volumes.

Personality traits are multidimensional traits comprising cognitive, emotional, and behavioral characteristics, and a wide array of cerebral structures mediate individual variability. Differences in personality traits covary with brain morphometry in specific brain regions, and neuroimaging studies showed structural or functional abnormalities of cerebellum in subjects with personality disorders, suggesting a cerebellar role in affective processing and an effect on personality characteristics. To test the hypothesis that cerebellar [white matter (WM) and cortex] volumes are correlated with scores obtained in the four temperamental scales of the Temperament and Character Inventory (TCI) by Cloninger, a total of 125 healthy participants aged 18-67 years of both genders (males = 52) completed the TCI and underwent magnetic resonance imaging. The scores obtained in each temperamental scale were associated with the volumes of cerebellar WM and cortex of right and left hemispheres separately by using linear regression analyses. In line with our hypothesis, novelty seeking (NS) scores were positively associated with WM and cortex cerebellar volumes. Harm avoidance (HA) scores were negatively associated with WM and cortex cerebellar volumes. The range of individual differences in NS and HA scores reflects the range of variances of cerebellar volumes. The present data indicating a cerebellar substrate for some personality traits extend the relationship between personality and brain areas to a structure up to now thought to be involved mainly in motor and cognitive functions, much less in emotional processes and even less in personality individual differences.

Effectiveness of short-term olanzapine in patients with bipolar I disorder, with or without comorbidity with substance use disorder.

OBJECTIVES: Prognosis of comorbid bipolar disorder (BD) and drug abuse is poor. We assessed the efficacy of olanzapine in manic or mixed BD patients, with (SUD) or without (N-SUD) comorbidity with substance use disorder (SUD) and its effect on drug abuse, days of abuse, and craving. METHODS: Eighty patients with BD-I (40 SUD) were hospitalized for a manic or mixed episode and received add-on olanzapine. Assessments were conducted at admission, discharge, and 4 and 8 weeks after discharge. Primary outcome was the proportion of responders and remitters in each group. We used a logistic regression model to adjust for possible confounders. We assessed craving and drug-abuse days with a visual analog scale and the Timeline Follow-Back. RESULTS: SUD and N-SUD were similar on response and remission, adjusted for sex, age, years ill, age at first episode, first episode depressive, number of hospitalizations, and duration of hospitalization (odds ratio, 1.09; 95% confidence interval, 1.02-2.29). Mood rating scores dropped significantly from baseline to end point in both groups. Timeline follow-back decreased in SUD from 22.5 to 7.3 at 8 weeks postdischarge, whereas craving dropped from 8.3 to 5.1 (P < 0.03). CONCLUSIONS: The effectiveness of short-term olanzapine in BD-I mania or mixed mania did not differ according to SUD comorbidity. Treatment was followed by less substance use/abuse and craving in comorbid bipolar-SUD patients.

The wnt pathway in mood disorders.

OBJECTIVES: To review the evidence of the involvement of the Wnt signalling pathway in mood disorders and in the action of drugs used to treat these disorders. METHODS: We performed a careful PubMed search using as keywords all possible terms relevant to the Wnt pathway and crossing them with each of four areas, i.e., developmental effects, behavioural effects, mood disorders, and drugs used in their treatment. Papers were selected on the basis of their content and their data used for discussion. RESULTS: Neurodevelopmental and behavioural data point to the possibility of involvement of the Wnt pathway in the pathophysiology of mood disorders. Clinical and post-mortem data are not sufficient to corroborate a definite role for Wnt alterations in any mood disorder. Combining genetic and pharmacological data, we may state that glycogen synthase kinase is the key molecule in bipolar disorder, as it is connected with many other signalling pathways that were shown to be involved in mood disorders, while Wnt molecules in the hippocampus appear to be mainly involved in depressive disorders. CONCLUSIONS: Altered Wnt signalling may play a role in the pathophysiology of mood disorders, although not a central one. It is premature to draw conclusions regarding the possible usefulness of Wnt manipulations in the treatment of mood disorders.

Life-saving electroconvulsive therapy in a patient with near-lethal catatonia.

A young woman with bipolar I disorder and comorbid catatonia on enteral nutrition from several months, developed a form of near-lethal catatonia with weight loss, pressure sores, muscle atrophy, electrolyte imbalance, and depression of vital signs. A compulsory treatment was necessary, and informed consent was obtained from her mother for electroconvulsive therapy (ECT). After 7 ECT sessions, the patient recovered and resumed feeding. ECT may save the life of a patient with catatonia provided that legal obstacles are overcome. Clinicians should carefully evaluate patients with near-lethal catatonia, taking into account the risk of pulmonary embolism and other fatal events. The medical-legal issues, which vary across state regulations, should be addressed in detail to avoid unnecessary and potentially harmful delay in intervention.

Neural functional correlates of empathic face processing.

OBJECTIVES: Empathy is a human trait related to the ability to share someone else's feelings, and emotional face processing is one of its measures. Functional Magnetic Resonance Imaging (fMRI) studies showed significant neural correlates of empathic face processing. We aimed to identify those brain areas most consistently involved in empathy for emotional faces. METHODS: We carried ALE meta-analysis of whole-brain data from fMRI studies during empathic face-processing tasks. We included 23 studies conducted on a total of 568 participants (247 males and 321 females, mean age 32.2 years). RESULTS: Emotional vs. control faces processing significantly correlated with activations of the left anterior cingulate cortex (BA 32), right precentral gyrus (BA 6), left amygdala, right superior frontal gyrus (BA 9), left middle occipital gyrus (BA 37), right insula (BA 13), left putamen, and left posterior cingulate cortex (BA 31). CONCLUSIONS: Empathy is a complex process correlating with bi-hemispheric cortico-limbic activations involved in emotional cue processing, self-other/same-different discrimination, perspective-taking, theory of mind, emotional arousal, and decision-making.

Psychosis risk syndrome comorbid with panic attack disorder in a cannabis-abusing patient affected by Arnold-Chiari malformation type I.

OBJECTIVE: An 18-year-old man with Arnold-Chiari malformation (ACM) type I developed sudden panic attacks. He also manifested sleep disorder, cannabis abuse, and psychosis-risk syndrome (PRS). Although with average-superior intelligence, he had executive dysfunction. This prompted us to explore the relation between ACM, cannabis abuse, PRS and panic disorder. METHOD: We report the case and briefly review the literature focusing on ACM and psychiatric disorders. RESULTS: Behavior therapy led to gradual abstinence from cannabis with disappearance of anxiety symptoms. The patient is currently well and maintained on omega-3 polyunsaturated fatty acids. CONCLUSIONS: Locus coeruleus compression and cannabis abuse may have triggered the symptoms, and the latter might also be PRS-related. PRS and anxiety symptoms should be explored in ACM patients to allow better prevention of psychosis and anxiety disorders.
