Effectiveness of early and intensive intervention on suicide prevention: CARS programme.

The aim of this study was to evaluate the outcomes of the Programme for Management of Suicidal Behaviour and Suicide Prevention (CARS). Individuals treated in the emergency department of University Hospital Marqués de Valdecilla for suicidal thoughts or attempts (N = 401) between 1-March-2016 and 31-December-2018 were considered. No randomization by patients or groups was performed. Student's t-test, chi-square and repeated measure analysis of variance were used. Kaplan-Meier survival function and Cox proportional hazard regression models were employed to estimate the risks of relapse. Outcome of those who voluntary enrol CARS were compared with treatment as usual (TAU) at 6- and 12-months follow-up. The results indicate a significant reduction and delayed occurrence of suicidal behaviour over a 12-month follow-up period with the CARS programme compared to TAU, along with a decreased frequency of hospital admissions. CARS programme demonstrates a substantial impact, significantly reducing the risk of recurrent suicidal behaviour by 35.5 % and the risk of repeated suicidal attempts by 47.2 % at the 12-month follow-up. The programme exhibits a dual protective effect, diminishing suicidal behaviour and fostering improved long-term outcomes. In conclusion, CARS effectively reduced suicidal behaviour recurrence, achieving significant decreases in suicidal thoughts, plans and attempts.

Comparison of Continuous Intracortical and Scalp Electroencephalography in Comatose Patients with Acute Brain Injury.

BACKGROUND: Depth electroencephalography (dEEG) is a recent invasive monitoring technique used in patients with acute brain injury. This study aimed to describe in detail the clinical manifestations of nonconvulsive seizures (NCSzs) with and without a surface EEG correlate, analyze their long-standing effects, and provide data that contribute to understanding the significance of certain scalp EEG patterns observed in critically ill patients. METHODS: We prospectively enrolled a cohort of 33 adults with severe acute brain injury admitted to the neurological intensive care unit. All of them underwent multimodal invasive monitoring, including dEEG. All patients were scanned on a 3T magnetic resonance imaging scanner at 6 months after hospital discharge, and mesial temporal atrophy (MTA) was calculated using a visual scale. RESULTS: In 21 (65.6%) of 32 study participants, highly epileptiform intracortical patterns were observed. A total of 11 (34.3%) patients had electrographic or electroclinical seizures in the dEEG, of whom 8 had both spontaneous and stimulus-induced (SI) seizures, and 3 patients had only spontaneous intracortical seizures. An unequivocal ictal scalp correlate was observed in only 3 (27.2%) of the 11 study participants. SI-NCSzs occurred during nursing care, medical procedures, and family visits. Subtle clinical manifestations, such as restlessness, purposeless stereotyped movements of the upper limbs, ventilation disturbances, jerks, head movements, hyperextension posturing, chewing, and oroalimentary automatisms, occurred during intracortical electroclinical seizures. MTA was detected in 18 (81.8%) of the 22 patients. There were no statistically significant differences between patients with MTA with and without seizures or status epilepticus. CONCLUSIONS: Most NCSzs in critically ill comatose patients remain undetectable on scalp EEG. SI-NCSzs frequently occur during nursing care, medical procedures, and family visits. Semiology of NCSzs included ictal minor signs and subtle symptoms, such as breathing pattern changes manifested as patient-ventilator dyssynchrony.

Intracortical focal non-convulsive status epilepticus causing cerebral hypoxia and intracranial hypertension.

We describe the pathophysiological consequences and long-term neurological outcome of a patient with acute brain injury (ABI) in whom intracortical electroencephalography (iEEG) captured an episode of prolonged focal non-convulsive status epilepticus (NCSE) that remained undetectable on scalp electroencephalography. A 53-year-old right-handed woman was admitted to hospital due to a large frontal left intraparenchymal hematoma. Over two and a half days, we captured recurrent non-convulsive electrographic and electroclinical seizures compatible with the diagnosis of intracortical focal NCSE. The patient remained sedated and a burst-suppression pattern was obtained. We also performed invasive brain multimodality monitoring including iEEG and measurements of intracranial pressure (ICP), partial brain tissue oxygenation (PbtO2) and brain temperature. During non-convulsive electrographic and electroclinical seizures, the values of PbtO2 decreased and those of ICP increased. Six months later, brain MRI revealed encephalomalacia localized to the left paramedial fronto-basal region. The neuropsychological assessment carried out one year after the injury showed scores below average in verbal learning memory, motor dexterity and executive functions. In summary, iEEG is a feasible innovative invasive technique that may be used to record non-convulsive electrographic and electroclinical seizures which remain invisible on the surface. Intracortical focal NCSE causes metabolic changes such as reduced brain oxygenation and an increase in ICP that can further damage previously compromised brain tissue.

Differences between psychiatric disorders in the clinical and functional effectiveness of an acute psychiatric day hospital, for acutely ill psychiatric patients. / Diferencias en la efectividad clínica y funcional, entre trastornos psiquiátricos, de un hospital de día psiquiátrico de agudos para pacientes con enfermedad mental aguda.

INTRODUCTION: Intensive treatment in acute day-care psychiatric units may represent an efficient alternative to inpatient care. However, there is evidence suggesting that this clinical resource may not be equally effective for every psychiatric disorder. The primary aim of this study was to explore differences between main psychiatric diagnostic groups, in the effectiveness of an acute partial hospitalization program. And, to identify predictors of treatment response. MATERIAL AND METHODS: The study was conducted at an acute psychiatric day hospital. Clinical severity was assessed using BPRS, CGI, and the HoNOS scales. Main socio-demographic variables were also recorded. Patients were clustered into 4wide diagnostic groups (i.e.: non-affective psychosis; bipolar; depressive; and personality disorders) to facilitate statistical analyses. RESULTS: A total of 331 participants were recruited, 115 of whom (34.7%) were diagnosed with non-affective psychosis, 97 (28.3%) with bipolar disorder, 92 (27.8%) with affective disorder, and 27 (8.2%) with personality disorder. Patients with a diagnosis of bipolar disorder showed greater improvement in BPRS (F=5.30; P=0.001) and CGI (F=8.78; P<0.001) than those suffering from psychosis or depressive disorder. Longer length of stay in the day-hospital, and greater baseline BPRS severity, were identified as predictors of good clinical response. Thirty-day readmission rate was 3%; at long-term (6 months after discharge) only 11.8% (N=39) of patients were re-admitted to a psychiatric hospitalization unit, and no differences were observed between diagnostic groups. CONCLUSIONS: Intensive care in an acute psychiatric day hospital is feasible and effective for patients suffering from an acute mental disorder. However, this effectiveness differs between diagnostic groups.

No sex differences in neuropsychological performance in first episode psychosis patients.

OBJECTIVE: The purpose of this study was to verify whether male patients with psychosis have greater neurocognitive impairment than female patients at illness onset. METHOD: Participants with a first episode of psychosis (74 women/86 men) and healthy controls (62 women/97 men) were assessed with an extensive neuropsychological test battery. RESULTS: Women in the clinical group were older at illness onset and had achieved higher formal education than men. This trend was the same for the control group. The patient group presented with lower premorbid IQ compared to healthy controls, and performed below for most neuropsychological tests. Women scored higher than men on a test of verbal memory, whereas men scored higher than women on a test of reaction time, visual memory, and a planning task. There were no group-by-sex interactions for any of the neuropsychological tests. CONCLUSION: The present study shows that at the onset of psychosis there are no differences between males and females in neuropsychological performance. The differential pattern of cognitive performance observed is similar to that in healthy males and females. Furthermore, females with a late onset of psychosis may represent a subgroup with specific visuospatial and problem solving impairments.

Course of cognitive deficits in first episode of non-affective psychosis: a 3-year follow-up study.

Cognitive dysfunctions are critical determinants of the quality of life and functionality in schizophrenia. Whether the cognitive deficits present at an early stage, are static or change across one's lifespan is still under debate. This study aims to investigate the long-term (3 years) course of cognitive deficits in a large and representative cohort of first episode schizophrenia spectrum patients (N=155),and evaluate their influence on disability. In addition, a healthy control sample (N=43) was also studied for comparison. This study evaluates the performance of patients and controls in a battery of cognitive assessments using baseline, 1-year and 3-year follow-up designs. The results show that, although cognitively outperformed by the controls at any time, the cognitive performance of the patients improved similar to the controls in all cognitive functions except verbal and visual memory. Even though the course of cognitive performance across the sample as a whole was stable, the subgroup of patients who experienced a cognitive decline had worse functionality and lesser amelioration of negative symptoms. Overall, there is no significant deterioration in the cognitive function in a group of first episode schizophrenia spectrum disorder patients, with the possible exception of tasks that were associated with episodic memory. However, patients whose cognitive performance demonstrated a declining trend may present with a poorer progression in terms of clinical and disability variables.

Homocysteine and cognition in first-episode psychosis patients.

In the last years, there has been growing evidence linking elevated homocysteine levels with cognitive dysfunction in several neurological and neuropsychiatric diseases. The aim of the present study was to investigate the potential relationship between elevated homocysteine levels and cognitive deficits in first-episode psychosis patients. Plasma levels and cognitive performance of 139 patients and 99 healthy volunteers were compared. Patients were classified as elevated homocysteine (>90 percentile for controls) and normal and compared on 22 cognitive outcome measures grouped into cognitive domains known to be impaired in schizophrenia. Patients had a statistically significant increase in plasmatic homocysteine levels. In addition, they presented with significantly increased cognitive deficits. However, no relationship between homocysteine levels and cognitive impairment was detected. These results suggest the need for further studies to clarify the role of homocysteine in the etiology and prognosis of psychosis.
