RESUMEN

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.

RESUMEN

PURPOSE: Optimal autonomic regulation and stress resilience might be considered critical elements of athletic performance. We hypothesize that a novel unitary autonomic index for sports (ANSIs), together with a somatic stress related symptom score (4SQ) might help characterize athletes who were eventually selected for the Rio 2016 Olympic Games Italian team (Rio +). METHODS: In this retrospective study we examined 778 athletes (age 24.4 ± 6.7 yrs) who underwent a planned yearly pre-participation screening. All athletes underwent clinical, autonomic and exercise ECG evaluation. The combination of vagal and sympathetic indices from RR variability into ANSIs was performed by radar plot and percent ranking of index variables. We assessed (Rio +) versus (Rio -) athletes also after subdivision into three sport intensity groups (low, mid and high intensity). RESULTS: Overall there were no significant differences between (Rio +) and (Rio -) athletes when considering individual spectral derived variables. Conversely, the unitary Index ANSIs was significantly higher in (Rio +) compared to (Rio -) athletes (respectively 54.5 ± 29.5 and 47.9 ± 28.4 p = 0.014). This difference was particularly evident (p = 0.017) in the group of athletes characterized by both high static and dynamic components. 4SQ was smaller in the (Rio +) group, particularly in the groups of athletes characterized by both low-medium static and dynamic components. CONCLUSIONS: ANSIs, a proxy of integrated cardiac autonomic regulation and simple assessment of resilience to stress, may differentiate Italian athletes who were eventually selected for participation in the 2016 Rio Olympic Games from those who were not, suggesting the possibility of a "winning functional phenotype".

RESUMEN

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.

RESUMEN

BACKGROUND: Spectral analysis of Heart Rate Variability (HRV) is a simple, non-invasive technique that is widely used in sport to assess sympatho-vagal regulation of the heart. Its employment is increasing partly due to the rising usage of wearable devices. However data acquisition using these devices may be suboptimal because they cannot discriminate between sinus and non-sinus beats and do not record any data regarding respiratory frequency. This information is mandatory for a correct clinical interpretation. METHODS: This study involved 974 elite athletes, all of them underwent a complete autonomic assessment, by way of Autoregressive HRV analysis. RESULTS: In 91 subjects (9% of the total population) we observed criticalities of either cardiac rhythm or respiration. Through perusal of one-lead ECG analysis we observed that 77 subjects had atrial or ventricular ectopy, i.e. conditions which impair stationarity and sinus rhythm. Running anyway autonomic nervous system analysis in this population, we observed that RR variance and raw values of LF and HF regions are significantly higher in arrhythmic subjects. In addition 14 subjects had slow (about 6 breath/min, 0.1Hz) respiration. This condition clouds the separation between LF from HF spectral regions of RR interval variability, respectively markers of the prevalent sympathetic and vagal modulation of SA node and of their synergistic interaction. CONCLUSIONS: Caution must be payed when assessing HRV with non-ECG wearable devices. Recording ECG signal and ensuring that respiratory rate is higher than 10 breath/min are both prerequisites for a more reliable analysis of HRV particularly in athletes.

RESUMEN

BACKGROUND: Long term endurance training, as occurring in elite athletes, is associated to cardiac neural remodeling in favor of cardioprotective vagal mechanisms, resulting in resting bradycardia and augmented contribution of cardiac parasympathetic nerve activity. Autonomic assessment can be performed by way of heart rate variability. This technique however provides multiple indices, and there is not yet complete agreement on their specific significance. Purpose of the study was to assess whether a rank transformation and radar plot could provide a unitary autonomic index, capable to show a correlation between intensity of individual work and quality of autonomic regulation. METHODS: We studied 711 (23.6±6.2 years) elite athletes that took part in the selection procedure for the 2016 Rio Olympic Games for the National Italian Olympic Committee (CONI). Indices from Heart Rate Variability HRV obtained at rest, during standing up and during recovery from an exercise test were used to compute a percent ranked unitary autonomic index for sport (ANSIs), taken as proxy of quality of autonomic regulation. RESULTS: Within the observed wide range of energy expenditure, the unitary autonomic index ANSIs appears significantly correlated to individual and discipline specific training workloads (r=0.25, P<0.001 and r=0.78, P<0.001, respectively), correcting for possible age and gender bias. ANSIs also positively correlates to lipid profile. CONCLUSIONS: Estimated intensity of physical activity correlates with quality of cardiac autonomic regulation, as expressed by a novel unitary index of cardiac autonomic regulation. ANSIs could provide a novel and convenient approach to individual autonomic evaluation in athletes.

RESUMEN

PURPOSE: Autonomic assessment might be useful in training management. We planned to assess whether oscillatory metrics of RR variability (such as LFnu) would be more efficient than static indices from low order statistics (RR variance) at discriminating laying rest from stand posture, as an analog of a shift to sympathetic dominance. METHODS: We studied a large population of elite Olympic athletes: a total of 406 athletes (162 females and 244 males, of similar age 21.7 and 24.4 years) participating to the selection for the upcoming 2016 Olympic games. We employed various methods to extract autonomic indices from RR variability and employed a stepwise statistical approach combining factor and discriminant analysis. RESULTS: We observed that that relative power of oscillatory components from spectral analysis of RR variability (such as LF or HF in nu) and indices from symbolic analysis (particularly 0V) clearly outperform RR variance in discriminating between two physiological conditions (laying rest and stand) related to posture and autonomic activation. CONCLUSIONS: In world class Olympic athletes we have shown that a small subset of RR variability indices, related to sympathovagal balance, may be more appropriate than RR variance to assess excitatory sympathetic autonomic responsiveness of the SA node. These findings may have practical implications for the use of RR variability in guiding training and predicting success in competitions.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Memantine, a non-competitive NMDA receptor antagonist approved for Alzheimer's disease with a good safety profile, is increasingly being studied in a variety of non-dementia psychiatric disorders. We aimed to critically review relevant literature on the use of the drug in such disorders. We performed a PubMed search of the effects of memantine in animal models of psychiatric disorders and its effects in human studies of specific psychiatric disorders. The bulk of the data relates to the effects of memantine in major depressive disorder and schizophrenia, although more recent studies have provided data on the use of the drug in bipolar disorder as an add-on. Despite interesting preclinical data, results in major depression are not encouraging. Animal studies investigating the possible usefulness of memantine in schizophrenia are controversial; however, interesting findings were obtained in open studies of schizophrenia, but negative placebo-controlled, double-blind studies cast doubt on their validity. The effects of memantine in anxiety disorders have been poorly investigated, but data indicate that the use of the drug in obsessive-compulsive disorder and post-traumatic stress disorder holds promise, while findings relating to generalized anxiety disorder are rather disappointing. Results in eating disorders, catatonia, impulse control disorders (pathological gambling), substance and alcohol abuse/dependence, and attention-deficit hyperactivity disorder are inconclusive. In most psychiatric non-Alzheimer's disease conditions, the clinical data fail to support the usefulness of memantine as monotherapy or add-on treatment However, recent preclinical and clinical findings suggest that add-on memantine may show antimanic and mood-stabilizing effects in treatment-resistant bipolar disorder.

RESUMEN

Patients with schizophrenia present deficits in multiple domains of cognition. The study of the relationship between cognitive performance and symptoms of schizophrenia has yielded heterogeneous results. The purposes of this study were to examine the extent of the relationship between psychopathologic symptoms, cognitive function, and subjective disturbances in a group of patients affected by schizophrenia spectrum disorders and to compare short-term with remitted patients. Seventy-nine patients meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for schizophrenia, schizophreniform disorder, and schizoaffective disorder were assessed through the Positive and Negative Syndrome Scale, the Frankfurt Complaint Questionnaire, and a neuropsychologic battery exploring the 7 Measurement and Treatment Research to improve Cognition in Schizophrenia cognitive domains (speed of processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning and problem solving, and social cognition) plus executive control. Neuropsychologic and psychopathologic variables were compared and correlated. Treatment groups did not differ in neuropsychologic and psychopathologic measures. The cognitive factor of the Positive and Negative Syndrome Scale correlated with worse performance on cognitive tasks and with higher scores on the Frankfurt Complaint Questionnaire 24 in the short-term, remitted, and combined groups. Subjective disturbances correlated with impaired executive control, reasoning and problem solving, and social cognition but not during the short-term phase. Both "objective" and subjective psychopathology are intertwined with cognitive function, suggesting some common underlying neural bases. The condition of being in a short-term or a remitted phase of the illness influences this interrelationship, regardless of the type of antipsychotic medication taken.

RESUMEN

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.

RESUMEN

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.
