RESUMO

OBJECTIVES: The study examines the clinical determinants of involuntary psychiatric hospitalization. Specifically, it investigates whether distinct clinical profiles of hospitalized patients can be discerned, what other characteristics they are linked with, and which profiles predict involuntary admission. METHODS: In this cross-sectional multicentre population study, data were collected for 1067 consecutive admissions in all public psychiatric clinics of Thessaloniki, Greece, during 12 months. Through Latent Class Analysis distinct patient clinical profiles were established based on Health of the Nation Outcome Scales ratings. The profiles were then correlated with sociodemographic, other clinical, and treatment-related factors as covariates and admission status as a distal outcome. RESULTS: Three profiles emerged. The "Disorganized Psychotic Symptoms" profile, combining positive psychotic symptomatology and disorganization, included mainly men, with previous involuntary hospitalizations and poor contact with mental health services and adherence to medication, indicating a deteriorating condition and chronic course. Τhe "Active Psychotic Symptoms" profile included younger persons with positive psychotic symptomatology in the context of normal functioning. The "Depressive Symptoms" profile, characterized by depressed mood coupled with nonaccidental self-injury, included mainly older women in regular contact with mental health professionals and treatment. The first two profiles were associated with involuntary admission and the third with voluntary admission. CONCLUSIONS: Identifying patient profiles allows the examination of the combined effect of clinical, sociodemographic, and treatment-related characteristics as risk factors for involuntary hospitalization, moving beyond the variable-centered approach mainly adopted to date. The identification of two profiles associated with involuntary admission necessitates the development of interventions tailored to chronic patients and younger persons suffering from psychosis respectively.

RESUMO

Introduction: Investigations of biofeedback (BF) and neurofeedback (NF) training for nicotine addiction have been long documented to lead to positive gains in smoking status, behavior and to changes in brain activity. We aimed to: (a) evaluate a multi-visit combined BF/NF intervention as an alternative smoking cessation approach, (b) validate training-induced feedback learning, and (c) document effects on resting-state functional connectivity networks (rsFCN); considering gender and degree of nicotine dependence in a longitudinal design. Methods: We analyzed clinical, behavioral, and electrophysiological data from 17 smokers who completed five BF and 20 NF sessions and three evaluation stages. Possible neuroplastic effects were explored comparing whole-brain rsFCN by phase-lag index (PLI) for different brain rhythms. PLI connections with significant change across time were investigated according to different resting-state networks (RSNs). Results: Improvements in smoking status were observed as exhaled carbon monoxide levels, Total Oxidative Stress, and Fageström scores decreased while Vitamin E levels increased across time. BF/NF promoted gains in anxiety, self-esteem, and several aspects of cognitive performance. BF learning in temperature enhancement was observed within sessions. NF learning in theta/alpha ratio increase was achieved across baselines and within sessions. PLI network connections significantly changed across time mainly between or within visual, default mode and frontoparietal networks in theta and alpha rhythms, while beta band RSNs mostly changed significantly after BF sessions. Discussion: Combined BF/NF training positively affects the clinical and behavioral status of smokers, displays benefit in smoking harm reduction, plays a neuroprotective role, leads to learning effects and to positive reorganization of RSNs across time.

RESUMO

Multiple Sclerosis (MS) is a chronic demyelinating and neurodegenerative disease of the central nervous system, with a variety of symptoms and uncertain course. It affects multiple facets of everyday life and since it results to some degree of disability, MS may cause deterioration of quality of life, both in mental and physical health. In this study, we investigated the role of demographic, clinical and, mostly, personal and psychological factors related to physical health quality of life (PHQOL). Our sample consisted of 90 patients with definite MS and the instruments used were: MSQoL-54 for PHQOL, DSQ-88 and LSI for the assessment of defense styles and mechanisms, BDI-II for depression, STAI for anxiety, SOC-29 as a measure of sense of coherence and FES for family relations. Important personality factors affecting PHQOL were the maladaptive and the self-sacrificing defense styles, the defense mechanisms of displacement and reaction formation, sense of coherence, while from the family environment, conflict affected PHQOL negatively and expressiveness positively. However, in the regression analysis none of these factors were found to be important. Multiple regression analysis showed the major impact of depression in PHQOL (negative correlation. Moreover, the fact that a person receives disability allowance, the number of the children, disability status and the event of a relapse in the current year, were also important negative factors for PHQOL. After a step-wise analysis, in which BDI and employment status were excluded, the most important variables were EDSS, SOC and relapse during the past year. This study confirms the hypothesis that psychological parameters play an important role in PHQOL and highlights the importance of the assessment of every PwMS by mental health professionals, as a routine. Not only psychiatric symptoms but also psychological parameters should be searched out in order to determine in which way each individual adjusts to the illness, thus impacting his PHQOL. As a result, targeted interventions, in personal or group level, or even in the family may enhance their QOL.

RESUMO

Background: Multiple sclerosis is a demyelinating chronic neurologic disease that can lead to disability and thus to deterioration of quality of life. Psychological parameters such as ego defense mechanisms, defense styles and family environment are important factors in the adaptation process, and as such they can play important roles in QoL. This study aims to assess the psychological factors as well as the clinical and demographic characteristics related to mental health quality of life (MHQoL). Methods: This was an observational, cross-sectional study conducted in a sample of 90 people with MS in the years 2018-2020. All participants completed the following questionnaires: MSQoL-54, DSQ-88, LSI, FES-R, SOC, BDI-II, STAI. Disability was assessed using EDSS. Results: In multiple linear regression, significant roles were played by depression (R2: 41.1%, p: 0.001) and, to a lesser extent, the event of a relapse (R2: 3.5%, p: 0.005), expressiveness (R2: 3.6%, p < 0.05) and image distortion style (R2: 4.5%, p: 0.032). After performing a hierarchical-stepwise analysis (excluding depression), the important factors were maladaptive defense style (R2: 23.7%, p: 0.002), the event of relapse (R2: 8.1%, p < 0.001), expressiveness (R2: 5.5%, p: 0.004) and self-sacrificing defense style (R2: 2.4%, p: 0.071). Conclusion: Psychological factors play important roles in MHQoL of people with multiple sclerosis. Thus, neurologists should integrate in their practice an assessment by mental health specialists. Moreover, targeted psychotherapeutic interventions could be planned i to improve QoL.

RESUMO

Hearing is a complex ability that extends beyond the peripheral auditory system. A speech in noise/competition test is a valuable measure to include in the test battery when attempting to assess an individual's "hearing". The present study compared syllable vs. word scoring of the Greek Speech-in-Babble (SinB) test with 22 native Greek speaking children (6-12-year-olds) diagnosed with auditory processing disorder (APD) and 33 native Greek speaking typically developing children (6-12-year-olds). A three-factor analysis of variance revealed greater discriminative ability for syllable scoring than word scoring, with significant interactions between group and scoring. Two-way analysis of variance revealed SinB word-based measures (SNR50%) were larger (poorer performance) than syllable-based measures for both groups of children. Cohen's d values were larger for syllable-based mean scores compared to word-based mean scores between groups for both ears. These findings indicate that the type of scoring affects the SinB's resolution capacity and that syllable scoring might better differentiate typically developing children and children with APD.

RESUMO

BACKGROUND: The aim of the current study was to explore the effect of gender, age at onset, and duration on the long-term course of schizophrenia. METHODS: Twenty-nine centers from 25 countries representing all continents participated in the study that included 2358 patients aged 37.21 ± 11.87 years with a DSM-IV or DSM-5 diagnosis of schizophrenia; the Positive and Negative Syndrome Scale as well as relevant clinicodemographic data were gathered. Analysis of variance and analysis of covariance were used, and the methodology corrected for the presence of potentially confounding effects. RESULTS: There was a 3-year later age at onset for females (P < .001) and lower rates of negative symptoms (P < .01) and higher depression/anxiety measures (P < .05) at some stages. The age at onset manifested a distribution with a single peak for both genders with a tendency of patients with younger onset having slower advancement through illness stages (P = .001). No significant effects were found concerning duration of illness. DISCUSSION: Our results confirmed a later onset and a possibly more benign course and outcome in females. Age at onset manifested a single peak in both genders, and surprisingly, earlier onset was related to a slower progression of the illness. No effect of duration has been detected. These results are partially in accord with the literature, but they also differ as a consequence of the different starting point of our methodology (a novel staging model), which in our opinion precluded the impact of confounding effects. Future research should focus on the therapeutic policy and implications of these results in more representative samples.

RESUMO

Advanced parental age at delivery and neurological soft signs (NSS) constitute risk factors for schizophrenia. The aim of the current study was to develop a neurobiological diagnostic index by combining them, and without the contribution of clinical symptomatology. The study sample included 133 patients suffering from schizophrenia according to DSM-IV-TR (77 males and 56 females; aged 33.55 ± 11.22 years old) and 122 normal controls (66 males and 56 females; aged 32.89 ± 9.91 years old). The assessment included the Neurological Evaluation Scale (NES), and a number of scales assessing the clinical symptoms and adverse effects. The statistical analysis included exploratory t-test, Pearson Correlation coefficient (R) and Discriminant Function Analysis (DFA). Exploratory t-tests and Pearson's R suggested that sex, parental age and NSS constitute independent components. On the basis of DFA results, the Psychotic Neurological Index was developed. At the cut-off PNI score of 8.5, sensitivity was equal to 94.74 and specificity to 93.44. The current is probably the first study to report on an easily obtainable diagnostic neurobiological marker with identifiable properties which is absolutely independent from the clinical manifestations and could serve in distinguishing between patients with schizophrenia and healthy controls with high efficacy.

RESUMO

The impact of the COVID-19 pandemic on the mental health of healthcare professionals is currently under research and prevalence of mental health symptoms across the world vary a lot. Moreover, knowledge and perceptions of healthcare professionals towards the new coronavirus is yet to be explored since very few data have been published to date. Thus, we decided to conduct a cross-sectional, web-based survey to measure the levels of depressive, anxiety and stress symptoms using the Depression, Anxiety and Stress Scale-21. The knowledge and perceptions of healthcare professionals towards the new coronavirus were also examined with a self-constructed questionnaire. Data were collected between April 19th and May 31st 2020. In total, 1484 professionals participated in the survey and 1064 completed it in full; 60.8% were females, 66.5% were physicians and 24.3% were first-line healthcare workers. The prevalence of at least moderate symptoms was 13% for depression, 11.9% for anxiety, and 11.3% for stress. Women, younger participants, residents in urban areas, having lower income and worse self-reported health status had higher scores in all outcomes. First-line healthcare workers also indicated higher anxiety scores compared to those who were not first responders. Regarding knowledge and perceptions, most participants agreed with the asymptomatic nature of the virus and its heightened danger for older individuals and those with underlying health conditions. Different views were expressed regarding the possibility of airborne transmission, its similarity to common flu, and the statements that the new coronavirus is manufactured and serves a specific purpose and that it is out of control. In conclusion, the results of our study suggest that the prevalence of depressive, anxiety and stress symptoms in Greek healthcare professionals is placed in the lower end of the range reported from various recent studies across the world. Nevertheless, professionals at risk should be monitored closely and supported when needed.airborne transmission, its similarity to common flu, and the statements that the new coronavirus is manufactured and serves a specific purpose and that it is out of control.

RESUMO

It is indicated that auditory perception deficits are present in schizophrenia and related to formal thought disorder. The purpose of the present study was to investigate the association of auditory deficits with cognitive impairment in schizophrenia. An experimental group of 50 schizophrenia patients completed a battery of auditory processing evaluation and a neuropsychological battery of tests. Correlations between neuropsychological battery scores and auditory processing scores were examined. Cognitive impairment was correlated with auditory processing deficits in schizophrenia patients. All neuropsychological test scores were significantly correlated with at least one auditory processing test score. Our findings support the coexistence of auditory processing disorder, severe cognitive impairment, and formal thought disorder in a subgroup of schizophrenia patients. This may have important implications in schizophrenia research, as well as in early diagnosis and nonpharmacological treatment of the disorder.

RESUMO

BACKGROUND: The aim of the current study was to explore the changing interrelationships among clinical variables through the stages of schizophrenia in order to assemble a comprehensive and meaningful disease model. METHODS: Twenty-nine centers from 25 countries participated and included 2358 patients aged 37.21 ± 11.87 years with schizophrenia. Multiple linear regression analysis and visual inspection of plots were performed. RESULTS: The results suggest that with progression stages, there are changing correlations among Positive and Negative Syndrome Scale factors at each stage and each factor correlates with all the others in that particular stage, in which this factor is dominant. This internal structure further supports the validity of an already proposed four stages model, with positive symptoms dominating the first stage, excitement/hostility the second, depression the third, and neurocognitive decline the last stage. CONCLUSIONS: The current study investigated the mental organization and functioning in patients with schizophrenia in relation to different stages of illness progression. It revealed two distinct "cores" of schizophrenia, the "Positive" and the "Negative," while neurocognitive decline escalates during the later stages. Future research should focus on the therapeutic implications of such a model. Stopping the progress of the illness could demand to stop the succession of stages. This could be achieved not only by both halting the triggering effect of positive and negative symptoms, but also by stopping the sensitization effect on the neural pathways responsible for the development of hostility, excitement, anxiety, and depression as well as the deleterious effect on neural networks responsible for neurocognition.

RESUMO

OBJECTIVE: The aim the study was to calculate remission, recovery and relapse rates in first episode patients with schizophrenia (FES) vs. patients at a later phase (non-FES). METHODS: Thirty-two FES and 101 non-FES patients took part in the study. The assessment included testing at baseline and at 1 year with the Positive and Negative Syndrome Scale (PANSS), Calgary Depression scale, State-Trait Anxiety Inventory (STAI), Udvalg for Kliniske Undersøgelser (UKU) scale, Simpson Angus, and General Assessment of Functioning (GAF) subscale. The statistical analysis included chi-square test and analysis of covariance. RESULTS: At baseline 15.62% FES vs. 10.89% non-FES patients were in remission; none of FES vs. 2.97% non-FES patients were in recovery. At endpoint, the respective figures were 12.50% vs. 25.00% and 3.12% vs. 3.96%. None of the differences in rates was significant between the two groups except from the percentage of patients being under medication (higher in the non-FES group). Baseline PANSS negative subscale (PANSS-N) was the only predictor of the outcome at endpoint. CONCLUSION: The current study reported very low rates of remission and recovery of patients with schizophrenia without any differences between FES and non-FES patients. One possibility is that the increased antipsychotic treatment compensates for the worsening of the illness with time. An accumulating beneficial effect of antipsychotic treatment suggested that early lack of remission is not prognostic of a poor outcome.

RESUMO

Auditory processing disorder (APD) is a specific deficit in the processing of auditory information along the central auditory nervous system. It is characterized mainly by deficits in speech in noise recognition. APD children may also present with deficits in processing of auditory rhythm. Rhythmic neural entrainment is commonly present in perception of both speech and music, while auditory rhythmic priming of speech in noise has been known to enhance recognition in typical children. Here, we test the hypothesis that the effect of rhythmic priming is compromised in APD children, and further assessed for correlations with verbal and non-verbal auditory processing and cognition. Forty APD children and 33 neurotypical ones were assessed through (a) WRRC, a test measuring the effects of rhythmic priming on speech in noise recognition, (b) a battery of auditory processing tests, commonly used in APD diagnosis, and (c) two cognitive tests, assessing working memory and auditory attention respectively. Findings revealed that (a) the effect of rhythmic priming on speech in noise recognition is absent in APD children, (b) it is linked to non-verbal auditory processing, and (c) it is only weakly dependent on cognition. We discuss these findings in light of Dynamic Attention Theory, neural entrainment and neural oscillations and suggest that these functions may be compromised in APD children. Further research is needed (a) to explore the nature of the mechanics of rhythmic priming on speech in noise perception and why the effect is absent in APD children, (b) which other mechanisms related to both rhythm and language are also affected in this population, and (c) whether music/rhythm training can restore deficits in rhythm effects.

RESUMO

The present study investigates the presence of Auditory Processing Disorder (APD) in schizophrenia and its association with symptomatology, especially Formal Thought Disorder (FTD). 50 patients with schizophrenia and 25 matched healthy controls completed a battery of three auditory processing tests. Positive and Negative Syndrome Scale (PANSS) and Thought, Language and Communication (TLC) scale were used to assess clinical symptoms. The patient group was divided into two subgroups, according to FTD severity. Auditory processing performance of the control group and the patient group was evaluated. Correlations between auditory processing scores and TLC scores, as well as auditory processing scores and PANSS scores were examined. Most of the patients, especially those with FTD, had auditory deficits that can be classified as APD. Patients showed impaired performance compared to controls in all tests. Total severity and specific factors of FTD, as well as other clinical symptoms and symptom categories were correlated with auditory processing performance. We provided evidence that APD may be present in schizophrenia and that FTD, as well as other clinical symptoms are associated with auditory processing deficits. There are important clinical implications for non-pharmacological interventions and early diagnosis of schizophrenia.
