SIGNIFICANTLY LOWER RIGHT MIDDLE CEREBRAL ARTERY BLOOD FLOW VELOCITY IN THE FIRST EPISODE OF PSYCHOSIS DURING NEUROCOGNITIVE TESTING
Background: Changes in cerebral hemodynamics have been reported in schizophrenia and proposed as underlying the cognitive
deficits seen in patients. The objective of our study was to compare changes of the cerebral blood flow velocity (BFV) during
neurocognitive tasks between the patients with the first episode of psychosis and healthy controls.
Subjects and methods: We recruited 46 patients with the first episode of psychosis (FEP), admitted to the University Hospital
Centre Zagreb during 2016-2017 and 41 control subjects. Transcranial Doppler ultrasonography monitoring of BFV in both middle
cerebral arteries was recorded during 25-minute long neurocognitive assessment with Phonemic Verbal Fluency test, Trial Making
Test B and Stroop test. Between every consecutive test resting periods were recorded.
Results: After the adjustment for age, sex and education by quantile regression, patients with FEP had significantly lower BFV
in middle cerebral arteries during the 3rd
NEUROCOGNITIVE PROFILES OF PATIENTS WITH THE FIRST EPISODE OF PSYCHOSIS AND SCHIZOPHRENIA DO NOT DIFFER QUALITATIVELY: A NESTED CROSS-SECTIONAL STUDY
Background: The aim of study was to analyze neurocognitive profiles in patients with first-episode psychosis (FEP) and patients with schizophrenia (SCH), and their correlations with other clinical features.
Subjects and methods: We performed a multicentric cross sectional study including 100 FEP and 100 SCH recruited from three Croatian hospitals during 2015-2017. Assessment included a set of neurocognitive tests, psychiatric scales and self-reporting questionnaires. The main analysis was done by multigroup latent profile analysis.
Results: Multigroup latent profile analysis resulted in three structurally equivalent neurocognitive profiles ("Best", "Medium", "Worst"), with differences in the severity of neurocognitive deficits measured with successfulness in solving domain specific tasks. The "Best" profile was statistically significantly more prevalent in FEP and "Worst" profile in the SCH. Negative symptom score was the highest in patients with the "Worst" profile and the lowest among those with the "Best" profiles.
Conclusions: Differences in neurocognitive profiles between FEP and SCH appear to be quantitative rather than qualitative nature, possibly reflecting a specific trait of illness that may progress over time. Defining neurocognitive profiles from the first episode of psychosis could help in tailoring individualized treatment options with focus on neurocognitive and negative symptoms and possible influence on patients\u27 overall clinical outcome
EFFICACY, SAFETY AND TOLERABILITY OF AUGMENTATIVE rTMS IN TREATMENT OF MAJOR DEPRESSIVE DISORDER (MDD): A PROSPECTIVE COHORT STUDY IN CROATIA
Background: An increasing body of research suggest that repetitive Transcranial Magnetic Stimulation (rTMS) is effective and
safe treatment option for patients with major depressive disorder (MDD). The Psychiatric Hospital “Sveti Ivan“has the first TMS
laboratory with rTMS and deep TMS (dTMS) in Croatia. The objective of this study was to assess the efficacy, safety and tolerability
of augmentative rTMS treatment vs standard treatment in Croatian patients with major depressive disorder (MDD).
Subjects and methods: Total of 93 MDD patients were enrolled; 41 of them were treated by augmentative rTMS and 52 were
treated by standard (psychopharmacotherapy and psychotherapy) therapy only. We delivered rTMS to the left dorsolateral
prefrontal cortex at 120% motor threshold (10 Hz, 4-second train duration), 3000 pulses per session using a figure-eight coil,
minimum of 20 sessions during four weeks. Our key outcome was the change in Hamilton Depression Scale (HAM-D17) result from
baseline to 4th week. Our secondary outcomes were changes in Hamilton Anxiety (HAM-A) and WHOQOL-BREF scales.
Results: After four weeks the changes of HAM-D17 and HAM-A results were significantly different between the group of patients
treated by augmentative rTMS (48% and 53% decrease, respectively) and the group of patients treated by the standard therapy alone
(24% and 30% decrease) (P=0.004, P=0.007). Absolute benefit increase defined as the difference between rates of remission (HAMD17
≤7) in rTMS and control group was 33% (P=0.001). Number of patients needed to treat with rTMS in order to achieve
remission in one patient was NNT=3. In a group of patients treated with augmentative rTMS 21/41 (51%), and in control group
17/52 (33%) were responders (P=0.071).
Conclusions: It seems that augmentative treatment with rTMS is more effective on depression and anxiety symptoms than
standard therapy in MDD with equal safety and tolerability. Randomized, controlled studies are required to verify this finding
Cystatin C, renal resistance index, and kidney injury molecule-1 are potential early predictors of diabetic kidney disease in children with type 1 diabetes
BackgroundDiabetic kidney disease (DKD) is the main cause of end-stage renal disease in patients with diabetes mellitus type I (DM-T1). Microalbuminuria and estimated glomerular filtration rate (eGFR) are standard predictors of DKD. However, these predictors have serious weaknesses. Our study aimed to analyze cystatin C, renal resistance index, and urinary kidney injury molecule-1 (KIM-1) as predictors of DKD.MethodsWe conducted a cross-sectional study in 2019 on a consecutive sample of children and adolescents (10–18 years) diagnosed with DM-T1. The outcome was a risk for DKD estimated using standard predictors: age, urinary albumin, eGFR, serum creatinine, DM-T1 duration, HbA1c, blood pressure, and body mass index (BMI). We conducted the analysis using structural equation modeling.ResultsWe enrolled 75 children, 36 girls and 39 boys with the median interquartile range (IQR) age of 14 (11–16) years and a median (IQR) duration of DM-T1 of 6 (4–9) years. The three focal predictors (cystatin C, resistance index, and urinary KIM-1) were significantly associated with the estimated risk for DKD. Raw path coefficients for cystatin C were 3.16 [95% CI 0.78; 5.53; p = 0.009, false discovery rate (FDR) < 5%], for renal resistance index were –8.14 (95% CI –15.36; –0.92; p = 0.027; FDR < 5%), and for urinary KIM-1 were 0.47 (95% CI 0.02; 0.93; p = 0.040; FDR < 5%).ConclusionCystatin C, renal resistance index, and KIM-1 may be associated with the risk for DKD in children and adolescents diagnosed with DM-T1. We encourage further prospective cohort studies to test our results
TRACE ELEMENTS CONCENTRATIONS ASSOCIATION WITH SCHIZOPHRENIA SYMPTOMS; A CROSS-SECTIONAL STUDY IN CROATIA
Background: Significant inconsistencies exist in findings on association of bio-elements (BE) concentrations and schizophrenia.
Hypothesis of this research was that different concentrations of BE are associated with different psychopathological schizophrenia
symptoms.
Subjects and methods: This cross-sectional study was performed from 2014 to 2016 at Psychiatric Hospital “Sveti Ivan” and
University Psychiatric Hospital “Vra
INTEGRATION OF COMPLEMENTARY BIOMARKERS IN PATIENTS WITH FIRST EPISODE PSYCHOSIS: RESEARCH PROTOCOL OF A PROSPECTIVE FOLLOW UP STUDY
In this project, we recruited a sample of 150 patients with first episode of psychosis with schizophrenia features (FEP) and 100 healthy controls. We assessed the differences between these two groups, as well as the changes between the acute phase of illness and subsequent remission among patients over 18-month longitudinal follow-up. The assessments were divided into four work packages (WP): WP1- psychopathological status, neurocognitive functioning and emotional recognition; WP2- stress response measured by saliva cortisol during a stress paradigm; cerebral blood perfusion in the resting state (with single photon emission computed tomography (SPECT) and during activation paradigm (with Transcranial Ultrasonography Doppler (TCD); WP3-post mortem analysis in histologically prepared human cortical tissue of post mortem samples of subjects with schizophrenia in the region that synaptic alteration was suggested by WP1 and WP2; WP4- pharmacogenetic analysis (single gene polymorphisms and genome wide association study (GWAS). We expect that the analysis of these data will identify a set of markers that differentiate healthy controls from patients with FEP, and serve as an additional diagnostic tool in the first episode of psychosis, and prediction tool which can be then used to help tailoring individualized treatment options. In this paper, we describe the project protocol including aims and methods and provide a brief description of planned post mortem studies and pharmacogenetic analysis
Clinical decision-making style preferences of European psychiatrists : Results from the Ambassadors survey in 38 countries
Background While shared clinical decision-making (SDM) is the preferred approach to decision-making in mental health care, its implementation in everyday clinical practice is still insufficient. The European Psychiatric Association undertook a study aiming to gather data on the clinical decision-making style preferences of psychiatrists working in Europe. Methods We conducted a cross-sectional online survey involving a sample of 751 psychiatrists and psychiatry specialist trainees from 38 European countries in 2021, using the Clinical Decision-Making Style - Staff questionnaire and a set of questions regarding clinicians' expertise, training, and practice. Results SDM was the preferred decision-making style across all European regions ([central and eastern Europe, CEE], northern and western Europe [NWE], and southern Europe [SE]), with an average of 73% of clinical decisions being rated as SDM. However, we found significant differences in non-SDM decision-making styles: participants working in NWE countries more often prefer shared and active decision-making styles rather than passive styles when compared to other European regions, especially to the CEE. Additionally, psychiatry specialist trainees (compared to psychiatrists), those working mainly with outpatients (compared to those working mainly with inpatients) and those working in community mental health services/public services (compared to mixed and private settings) have a significantly lower preference for passive decision-making style. Conclusions The preferences for SDM styles among European psychiatrists are generally similar. However, the identified differences in the preferences for non-SDM styles across the regions call for more dialogue and educational efforts to harmonize practice across Europe.Peer reviewe
