RESUMO

PURPOSE: The treatment of mental disorders has shifted from inpatient wards to community-based settings in recent years, but some patients may still have to be admitted to inpatient wards, sometimes involuntarily. It is important to maintain the length of hospital stay (LoS) as short as possible while still providing adequate care. The present study aimed to explore the factors associated with the LoS in involuntarily admitted psychiatric patients. METHODS: A ten-year retrospective chart review of 332 patients admitted involuntarily to the inpatient psychiatric ward of the General University Hospital of Ioannina, Northwestern Greece, between 2008 and 2017 was conducted. RESULTS: The mean LoS was 23.8 (SD = 33.7) days and was relatively stable over the years. Longer-stay hospitalization was associated with schizophrenia-spectrum disorder diagnosis, previous hospitalizations and the use of mechanical restraint, whereas patients in residential care experienced significantly longer LoS (52.6 days) than those living with a caregiver (23.5 days) or alone (19.4 days). Older age at disease onset was associated with shorter LoS, whereas no statistically significant differences were observed with regard to gender. CONCLUSION: While some of our findings were in line with recent findings from other countries, others could not be replicated. It seems that multiple factors influence LoS and the identification of these factors could help clinicians and policy makers to design more targeted and cost-effective interventions. The optimization of LoS in involuntary admissions could improve patients' outcomes and lead to more efficient use of resources.

RESUMO

Background and Objectives: The study aims to provide a comprehensive neuropsychological analysis of psychotic spectrum disorders, including schizophrenia, bipolar disorder, and depression. It focuses on the critical aspects of cognitive impairments, diagnostic tools, intervention efficacy, and the roles of genetic and environmental factors in these disorders. The paper emphasizes the diagnostic significance of neuropsychological tests in identifying cognitive deficiencies and their predictive value in the early management of psychosis. Materials and Methods: The study involved a systematic literature review following the PRISMA guidelines. The search was conducted in significant databases like Scopus, PsycINFO, PubMed, and Web of Science using keywords relevant to clinical neuropsychology and psychotic spectrum disorders. The inclusion criteria required articles to be in English, published between 2018 and 2023, and pertinent to clinical neuropsychology's application in these disorders. A total of 153 articles were identified, with 44 ultimately included for detailed analysis based on relevance and publication status after screening. Results: The review highlights several key findings, including the diagnostic and prognostic significance of mismatch negativity, neuroprogressive trajectories, cortical thinning in familial high-risk individuals, and distinct illness trajectories within psychosis subgroups. The studies evaluated underline the role of neuropsychological tests in diagnosing psychiatric disorders and emphasize early detection and the effectiveness of intervention strategies based on cognitive and neurobiological markers. Conclusions: The systematic review underscores the importance of investigating the neuropsychological components of psychotic spectrum disorders. It identifies significant cognitive impairments in attention, memory, and executive function, correlating with structural and functional brain abnormalities. The paper stresses the need for precise diagnoses and personalized treatment modalities, highlighting the complex interplay between genetic, environmental, and psychosocial factors. It calls for a deeper understanding of these neuropsychological processes to enhance diagnostic accuracy and therapeutic outcomes.

RESUMO

Background: Alexithymia and atypical gut-brain signaling have been linked to the pathophysiology of inflammatory bowel disease (IBD). We herein assessed IBD patients' alexithymia levels and interoceptive abilities, and detected potential correlations with psychological distress, symptom severity and disease activity, and inflammation indices. Methods: Adult IBD outpatients and healthy controls were recruited. Alexithymia was assessed using the Toronto Alexithymia Scale, interoceptive accuracy using the Heartbeat Counting Test (cardiac interoception) and the Water Load Test-II (gastric interoception), and interoceptive sensibility using the Multidimensional Assessment of Interoceptive Awareness (MAIA). Results: Forty-one patients with Crohn's disease (CD), 16 with ulcerative colitis (UC), and 50 healthy controls were included. In CD patients, the level of externally oriented thinking and total alexithymia score were correlated with disease activity (P=0.027 and P=0.047, respectively), while in UC patients difficulties in identifying emotions were linked to disease activity (P=0.007). In CD patients, the Noticing, Not-Worrying and Emotional Awareness MAIA subscale score were correlated with C-reactive protein levels (P=0.005, P=0.048 and P=0.005), the Noticing subscale score with interleukin (IL)-1ß levels (r=-0.350, P=0.039), the Not-Distracting subscale score with IL-6 levels (r=-0.402, P=0.017), and the Emotional Awareness subscale score with IL-1ß (r=-0.367, P=0.030) and IL-6 (r=-0.379, P=0.025) levels. Finally, in UC patients, the Not-Worrying subscale score was significantly associated with IL-6 levels (r=-0.532, P=0.049), while difficulties in identifying emotions were linked to IL-8 levels (r=0.604, P=0.022). Conclusion: Emotional and interoceptive processing is associated with IBD disease activity, suggesting a potential implication for IBD pathophysiology.

RESUMO

OBJECTIVE: Antipsychotic drugs constitute the basis of schizophrenia therapy; however, available pharmaceutical agents lack efficacy for treating the cognitive deficits caused by the illness. The aim of the present work is to present current data regarding cognitive rehabilitation of schizophrenia, providing information and guidance to health professionals. METHOD: A literature search was conducted in the PubMed and Google Scholar Databases from inception up to 1/9/2022. Relevant articles were explored for factors affecting cognitive function, including genetics, psychopathology, time in the course of the illness, and drug therapy. Characteristics and outcome of cognitive rehabilitation programs are briefly presented. RESULTS: A total of 562 relevant articles were retrieved, 39 of which were selected for the review. Factors contributing to a favorable outcome are young age, early phase of disease, symptomatic control of hostility and conceptual disorganization, lack of negative symptoms, management of drug side effects, and cognitive and cortical reserve. Some evidence for a procognitive effect seems to exist for atypical antipsychotics, clozapine, aripiprazole, memantine, modafinil, d-serine, and cycloserine. The Val/Val polymorphism of the COMT gene seems to be associated with worse outcome. Specific remediation strategies include programs such as Cognitive Enhancement Therapy (CET), Cognitive Adaptation Training (CAT), and RehaCom Cognitive Therapy Software, among others, all employing a range of techniques, from paper-and-pencil to computer-assisted, bottom-up, or top-down approaches, and varying neurocognitive targets. CONCLUSION: Cognitive symptoms, closely related to functional impairment, still remain a therapeutic challenge. Cognitive rehabilitation strategies are as yet the only treatment modality offering cognitive improvement to patients who struggle to recover.

RESUMO

BACKGROUND: Recently, cognitive deficits occurring in rheumatic diseases have attracted scientific attention. Cognitive symptoms in patients with Rheumatoid Arthritis (RA) and Systemic Sclerosis (SSc) have not been thoroughly studied. This study aimed to assess cognitive function and its relationship with depressive symptoms in RA and SSc and compare it to mild neurocognitive disorder due to Alzheimer's disease (MiND) and to individuals without cognitive impairment. METHODS: Cognitive function and depressive symptoms were tapped with the Cognitive Telephone Screening Instrument plus (COGTEL+), the Serial Seven Test (SST), the Mini-Mental State Examination (MMSE) and the Geriatric Depression scale-15 (GDS), respectively. Statistical analyses included between groups-, correlation- and regression analyses. Demographic characteristics were considered in the regression models. RESULTS: The study included 30 individuals with RA, 24 with SSc, 26 adults without cognitive impairment and 33 individuals with MiND. Lower performance in verbal short-term memory, concentration/attention, verbal fluency and MMSE in patients with RA compared to individuals without cognitive impairment was detected. Of note, performance on verbal fluency, concentration/attention, inductive reasoning and MMSE was lower in RA compared to MiND. Individuals with SSc performed worse in verbal fluency and in MMSE in comparison to adults without cognitive deficits. Verbal fluency deficits in SSc exceeded that in MiND. Performance on MMSE, COGTEL+, prospective memory, working memory, verbal fluency and concentration/attention was related to GDS scores, which did not vary across the groups. CONCLUSIONS: Patients with RA and SSc encountered cognitive dysfunction, which partially pertains to depressive symptoms. Of note, the severity of cognitive dysfunction in many cases exceeded that of MiND.

RESUMO

This study estimated the crude prevalence of autism spectrum disorders (ASD) in Greece in 2021. A retrospective study was conducted for 2021 using data provided for research purposes for the first time by the Greek National Health Service Organization for Healthcare Services Provision (EOPYY) related to the ICD-10 diagnosis codes F84.0-F84.9 (ASD). Treatments were categorized by gender, age, and location. Statistical analysis was performed using the open-source software R. In total, 15,706 children aged 2-17 years were registered with ASD: 12,380 boys and 3326 girls. In total, 6,117,910 therapies were prescribed: 4,844,173 for boys and 1,273,737 for girls. Boys are estimated to be diagnosed 3.5 times more often than girls. On average, approximately 390 treatments are prescribed per person per year for both sexes. The annual prevalence is estimated at 0.94%, ranging from 0.42% to 1.44% depending on geographic region. Our findings provide evidence-based data for the planning of policies regarding health, education, and employment for people with ASD. The number of children and treatments makes ASD a public health concern to support children and their families and ensure equal participation in all aspects of society.

RESUMO

BACKGROUND: Involuntary psychiatric admissions are a widely used practice despite ethical concerns about coercion. There are particular concerns that vulnerable groups, such as single, unemployed or racial minorities, may be more subjected to such practices. AIM: We aimed to investigate the social patterns of involuntary psychiatric admissions from 2008 to 2017 at University General Hospital in Ioannina, Greece. METHOD: We retrospectively assessed inpatient records from 2008 to 2017 of patients admitted to the Department of Psychiatry of the Ioannina University General Hospital, Northwestern Greece. Alternative patients of alternative years were selected for inclusion; this yielded 332 patients involuntarily admitted, corresponding to 28.5% of total involuntary psychiatric admissions. RESULTS: Over the 10-year period, the overall numbers of annual involuntary psychiatric admissions remained relatively stable, as did the length of hospital stay (mean = 23.8 days). The most common disorder upon admission was schizophrenia spectrum disorders, accounting for approximately two-thirds of all admissions, followed by mood disorders (about 20%). There was evidence that people who lacked social support or experienced financial hardship were more greatly represented among those admitted: 70.2% of admitted patients were single and 64.8% were unemployed. Most patients had been admitted to the psychiatric ward in the past (64.2%). CONCLUSION: Our study indicates potentially worrisome evidence that patients who are in vulnerable positions are at elevated likelihood of being involuntarily admitted to psychiatric wards. Future research is needed to evaluate the socio-demographic patterning of involuntary admissions in other European countries.

RESUMO

Clozapine is the gold standard for treatment-resistant schizophrenia. Serious and even life-threatening adverse effects, mostly granulocytopenia, myocarditis, and constipation, are of great clinical concern and constitute a barrier to prescribing clozapine, thus depriving many eligible patients of a lifesaving treatment option. Interestingly, clozapine presents variable pharmacokinetics affected by numerous parameters, leading to significant inter- and intra-individual variation. Therefore, therapeutic drug monitoring of plasma clozapine levels confers a significant benefit in everyday clinical practice by increasing the confidence of the prescribing doctor to the drug and the adherence of the patient to the treatment, mainly by ensuring effective treatment and limited dose-related side effects. In the present systematic review, we aimed at identifying how a full range of adverse effects relates to plasma clozapine levels, using the Jadad grading system for assessing the quality of the available clinical evidence. Our findings indicate that EEG slowing, obsessive-compulsive symptoms, heart rate variability, hyperinsulinemia, metabolic syndrome, and constipation correlate to plasma clozapine levels, whereas QTc, myocarditis, sudden death, leucopenia, neutropenia, sialorrhea, are rather unrelated. Rapid dose escalation at the initiation of treatment might contribute to the emergence of myocarditis, or leucopenia. Strategies for managing adverse effects are different in these conditions and are discussed accordingly.

RESUMO

Τhe COVID-19 pandemic has mental health implications for both healthcare workforces and general population, particularly in regions heavily hit by the crisis. Τhe study aimed (i) to investigate anxiety- and depression severity differences between staff of a COVID-19 treatment unit (N = 84) and a hospital without such a unit (N = 55) in comparison to participants of a convenience general population online survey (N = 240) and (ii) to explore relations between such symptoms and hospital staff reaction to COVID-19 in a low COVID-19 burden setting. Anxiety was studied with the Generalized Anxiety Disorder 7-Item in hospital workforces and with the Hospital Anxiety Depression Scale (HADS) in online survey participants. Depression symptoms were assessed with the Patient Health Questionnaire-9 in hospital employees and the HADS in the online survey sample. Symptoms were classified as absent/minimal, borderline abnormal or indicating clinical caseness. Staff reaction to COVID-19 was tapped with a 9-item-questionnaire and the 22-item Impact of Event Scale-revised (IES-R). Proper tests for differences and stepwise ordered logistic regression models were employed. Anxiety- and depression severity was higher in hospital workforces than in online survey participants (P < 0.05). Anxiety was more severe in frontline- compared to backstage employees (P < 0.001) was inversely correlated with age (P = 0.011) and positively with avoidance (P = 0.028). Both anxiety and depression symptoms related to intrusion symptoms (P < 0.001). Regarding the relatively long data collection period, an inverse association between crisis duration and depression symptoms was detected (P = 0.025). These observations point to the urgent need for distress-mitigating interventions for hospital workforces even in low COVID-19 burden settings.

RESUMO

PURPOSE: The present study aims to investigate the course of psychological symptoms through chemotherapy in a sample of primary caregivers of patients with cancer and to examine all possible correlations between psychological distress and demographic characteristics. METHODS: In this prospective study, 112 primary family caregivers of cancer patients were evaluated. Symptom checklist 90 revised (SCL-90-R) was administered to assess their pathological symptoms, the Hospital Anxiety and Depression Scale (HADS) to assess depression and anxiety. There was an evaluation at the beginning of chemotherapy and a second at the end of the patients' intravenous chemotherapy treatment (EOT). RESULTS: A total of 112 primary caregivers were initially enrolled in the study, and 99 (88.4%) completed it. Caregivers' psychopathology was low to moderate at both points of time (baseline and EOT). However, a considerable decrease in the Global Severity Index (GSI) emerged over time. CONCLUSIONS: At EOT, participants reported statistically significant decreases in five aspects of SCL 90, namely Depression, phobic anxiety, obsessive-compulsive symptoms, somatization, and psychoticism. A notable finding was that female caregivers were significantly more distressed, especially when providing care to a male recipient.

RESUMO

BACKGROUND: Telephone-based neurocognitive instruments embody valuable tools in identifying cognitive impairment in research settings and lately also in clinical contexts due to the pandemic crisis. The accuracy of the Cognitive Telephone Screening Instrument (COGTEL) in detecting mild- (MiND) and major (MaND) neurocognitive disorder has not been studied yet. OBJECTIVE: Comparison of the utility of COGTEL and COGTEL+, which is enriched with orientation items, with the modified Mini-Mental State Examination (3MS) in detecting MiND and MaND due to Alzheimer's disease (AD) and assessment of the impact of COGTEL face-to-face-versus telephone administration on individual performance. METHODS: The study included 197 cognitively intact individuals (CI), being at least 45 years old, 95 and 65 patients with MiND and MaND due to AD, respectively. In 20 individuals COGTEL was administered both in face-to-face and telephone sessions. Statistical analyses included proportional odds logistic regression models, stratified repeated random subsampling used to recursive partitioning to training and validation set (70/30 ratio), and an appropriate F-test. RESULTS: All studied instruments were significant predictors of diagnostic outcome, but COGTEL+ and 3MS explained more variance relative to the original COGTEL. Except for the validation regression models including COGTEL in which the average misclassification error slightly exceeded 15%, in all other cases the average misclassification errors (%) were lower than 15%. COGTEL administration modality was not related to systematic over- or underestimation of performance on COGTEL. CONCLUSION: COGTEL+ is a valuable instrument in detecting MiND and MaND and can be administered in face-to-face or telephone sessions.

RESUMO

BACKGROUND: Although self-rating mania scales have been developed, a lack of such instruments validated for the Greek population is noted. This study aims to examine the validity, reliability and psychometric properties of the Altman Self Rating Mania Scale (ASRM) adapted in Greek (G-ASRM). METHODS: A sample of 86 consecutive inpatient and outpatient bipolar patients diagnosed by the DSM-5 criteria and 37 healthy controls were assessed by using the Young Mania Rating Scale (YMRS) and the Montgomery Asberg Depression Rating Scale (MADRS), and self-administered the G-ASRM. Factor analysis, test-retest analysis, measurement invariance tests, mean differences, Pearson's Correlation analysis and ROC analysis were used to confirm the validity of G-ASRM as a scale, test its reliability, study its psychometric properties in different subgroups and establish a cut-off value for indicating the presence of (hypo)mania in BD patients. Also, regression models were built to expose dependencies between YMRS and G-ASRM items. RESULTS: Monofactoriality of the scale was verified, based on Exploratory Factor Analysis (EFA). Cronbach's alpha was 0.895. G-ASRM is highly correlated with YMRS (r = 0.856, p < 0.0005) and uncorrelated with MADRS (r = -0.051, p = 0.623). Test- retest r-coefficient was calculated at 0.85. The optimal cut-off score, set at ≥6 for (hypo)mania assessment, is in agreement with the results reported for the original version. Limitations of the study are that the scale was not normed on diagnostic groups other than bipolar, nor was it administered longitudinally, so as to assess its sensitivity to symptom changes overtime. CONCLUSION: The G-ASRM can be validly and reliably used in the Greek population for the assessment of (hypo)mania in bipolar patients.

RESUMO

BACKGROUND: This study has assessed health-related quality of life (HRQoL) and psychological distress between public sector professional groups. METHODS: Short Form-36 Health Survey (SF-36) and Hospital Anxiety and Depression Scale (HADS) were administered to healthcare personnel, schoolteachers, and municipality and regional personnel in the region of Western Greece. Mean scores on all SF-36 dimensions and HADS were compared among these professional groups as well as with the Greek national norms to assess if there were significant differences between our study sample and the general population. RESULTS: Healthcare personnel reported significantly lower SF-36 scores than teachers and municipality employees. Women reported poorer HRQoL than men on all SF-36 dimensions. This overall low score for health care workers masks the fact that male health care workers, primarily medical doctors, actually scored better than women, primarily nurses and auxiliary personnel. Average mean scores on all SF-36 dimensions reported by nurses and auxiliary personnel in healthcare were considerably lower than the ones from employees in all other occupational types. The impact on HRQoL observed mainly in vitality, social functioning and mental health was important. Many participants have shown psychological burden and depression. CONCLUSIONS: The health inequalities among healthcare employees are significant. This study is important to suggest taking measures for improving the HRQoL of health workers.

RESUMO

BACKGROUND: SARS-CoV-2 has rapidly spread worldwide, threatening public health and financial and social life. AIMS: The current study's aim was to determine the prevalence of psychological distress and post-traumatic stress symptoms in the Greek population during the first COVID-19 lockdown, and to detect potential correlates. METHOD: An anonymous online survey was conducted between 10 April and 4 May 2020, to collect information regarding people's psychological functioning and COVID-19-related perceptions. RESULTS: A total of 1443 individuals completed the survey; 293 (20%) reported clinically significant anxiety symptoms, 188 (12.9%) reported clinically significant depressive symptoms and 506 (36.4%) suffered from definite post-traumatic stress disorder. Anxiety symptoms were independently associated with female gender (ß = 1.281, 95% CI 0.808-1.755, P < 0.001), educational level (ß = -1.570, 95% CI -2.546 to -0.595, P = 0.002), perceived severity (ß = -1.745, 95% CI -3.146 to -0.344, P = 0.015) and COVID-19-related worry (ß = 7.633, 95% CI 6.206-9.060, P < 0.001). Depressive symptoms were strongly correlated with educational level (ß = -1.298, 95% CI -2.220 to -0.377, P = 0.006), perceived severity (ß = -1.331, 95% CI -2.579 to -0.082, P = 0.037) and COVID-19-related worry (ß = 4.102, 95% CI 2.769-5.436, P < 0.001). Finally, post-traumatic stress symptoms were linked to female gender (ß = 6.451, 95% CI 4.602-8.299, P < 0.001), educational level (ß = -5.737, 95% CI -9.479 to -1.996, P = 0.003), psychiatric history (ß = -4.028, 95% CI -6.274 to -1.782, P < 0.001) and COVID-19-related worry (ß = 23.865, 95% CI 18.201-29.530, P < 0.001). CONCLUSIONS: A significant percentage of the population reported clinically important anxiety, depressive and post-traumatic stress symptoms. Women, less-educated individuals and people with a psychiatric history appeared more vulnerable to the pandemic's psychological impact.

RESUMO

Apolipoprotein E (APOE) ε, catechol-O-methytranferase (COMT) Val108/158Met and brain-derived neurotrophic factor (BDNF) Val66Met single nucleotide polymorphisms (SNPs) were shown to affect stress perception and response. The present study explored possible associations between these SNPs and changes in subclinical anxiety- and depressive symptoms, sense of coherence (SOC) and vital exhaustion (VE) during compulsory basic military training. The study encompassed 179 conscripts of a training base in Greece. The neuropsychiatric assessment was based on the Beck Depression Inventory, the State-Trait Anxiety Inventory, the Antonovsky SOC scale and the Maastricht Questionnaire. It was conducted at three time points of the 19-day basic military training: on day one (baseline), day six (follow-up I) and day 13 (follow-up II). Statistical analyses included Mann-Whitney test, Chi-square test and cross-sectional time series regression models based on the Skillings-Mack statistic. APOE ε4 non-carriers encountered significant changes in anxiety- and depressive symptoms and SOC (in all cases P < 0.001) over the observation period, whilst ε4 carriers did not. The changes in anxiety, depressive symptoms and SOC attained statistical significance in both BDNF Met66 carriers (in all cases P < 0.001) and non-carriers (P = 0.036; < 0.001; < 0.001, respectively) as well as in COMT Met108/158 carriers (P = 0.004; < 0.001; < 0.001, respectively) and non-carriers (P = 0.02; 0.01; 0.021, respectively. Changes over time in VE were not significant (P > 0.05). The observed resistance of APOE ε4 carriers vs non-carriers to changes in anxiety- and depressive symptoms and SOC when exposed to a stressful environment may point to superior coping capacities of healthy young men carrying the ε4 allele.

RESUMO

BACKGROUND: Cognitive impairment is common in multiple sclerosis (MS), but deficits tend to be more pronounced in progressive MS, negatively impacting daily functional capacity. Despite this, most cognitive rehabilitation (CR) interventions to date have focused on relapsing-remitting MS (RRMS). Moreover, information on the efficacy of CR in progressive MS is limited and controversial. The present study investigated the efficacy of a home based, computer assisted cognitive rehabilitation (HBCACR) intervention (RehaComTM software) exclusively in a Secondary Progressive Multiple Sclerosis (SPMS) sample. METHODS: This was a randomized, multi site, sham controlled trial. Thirty six (36) individuals with SPMS, naïve to the RehaCom software, with cognitive deficits were randomized to the treatment (IG; n= 19) or control group condition (CG; n=17). Treatment with the RehaCom modules consisted of 24 domain and task specific, 45 minute session's over an 8-week period, three sessions per week, applied by each patient at home. The CG completed non specific computer based activities at home with the same frequency and duration. Primary cognitive outcome measures included the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) battery, and secondary outcome measures for depression (BDI-FS), fatigue (MFIS), and quality of life (EuroQol EQ-5D) visual analogue scale (VAS). RESULTS: The two groups were well matched on demographic and clinical characteristics, cognitive reserve and severity of cognitive deficits at baseline assessment. At post treatment assessment the IG group showed significant improvements with large effect sizes; in verbal learning [z = -4.759, p <.0005, g = 2.898], visuospatial memory [z = -3.940, p <.0005, g = 1.699] and information processing speed [z= -4.792, p <.0005, g = 2.980], compared with the sham control group. We also found significant between group differences on physical [z=-3.308, p = .001, g= -.604], cognitive [z = -4.011, p <.0005, g = -1.654], psychosocial [z= 3.308, p = .010, g = -.940], and general fatigue impact [z= -2.623, p = .008, g = -.519], depression severity [z = -2.730, p = .006, g = -.519], and quality of life [z= -4.239, p <.0005, g = -1.885] in favor of the treated group. CONCLUSION: These data provide the first evidence supporting the efficacy of computer based restorative cognitive rehabilitation applied at home exclusively in SPMS patients, suggesting that adaptive neuroplasticity may occur after functional cognitive training in progressive MS. Improved cognitive functioning in combination with mood augmentation appear to have ameliorated fatigue, which impacted daily functioning activity and culminated in improved health related quality of life.

RESUMO

Major depressive disorder (MDD) is a chronic, severe psychiatric illness with an incidence of 3% worldwide. MDD patients have a significantly impaired quality of life and reduced life expectancy compared to unaffected individuals, the latter being largely accounted for by an increased incidence of suicide and cardiovascular disorders. The premature mortality observed in MDD has been considered a signature of accelerated aging, a hypothesis supported by data showing altered functioning and morphology of several brain regions that are typically present in the aging population. Telomere shortening is a hallmark of cellular aging, and as such several studies explored the involvement of disrupted telomere dynamics in MDD, reporting contrasting findings. In the current study, we measured leukocyte telomere length (LTL) in a sample of 54 MDD patients and 47 non-psychiatric controls characterized for response to antidepressant treatment. After correcting for age, sex, and body mass index, we showed significantly reduced LTL in affected individuals compared to controls (beta = -.22, p = .02). There was no difference in LTL between treatment resistant or responsive MDD patients. Moreover, we observed no correlation between lifetime exposure to antidepressants and LTL. Our study showed that MDD patients have shorter telomeres compared to controls, supporting the hypothesis of accelerated aging in this disorder. However, LTL seemed not to be influenced by antidepressant treatment or to correlate with clinical response to these antidepressants. Further investigations in larger samples and possibly with longitudinal design are warranted to elucidate the role of altered telomere dynamics in MDD.

RESUMO

Recent research has fueled a debate concerning the role of nicotine in the emergence of schizophrenia. The three main hypotheses are: (a) the self-medication effect, (b) the causal relationship hypothesis, or (c) the shared diathesis hypothesis. To explore this role, the study of nicotine consumption during the initial prodromal phase of schizophrenia offers important opportunities. In the present work, 10 relevant studies are reviewed, out of 727 retrieved citations, in order to address questions regarding the prevalence of smoking in the prodromal period, the time of smoking initiation, existing patterns of tobacco use in relation with the escalation of prodromal symptoms into first psychotic episode, and potential differences in symptomatology between smokers and nonsmokers. Even though there was considerable heterogeneity among studies, relevant findings are discussed. Prevalence of nicotine use during the prodromal period was reported to be 16.6-46%. Tobacco use was found to be taken up most often before or during the prodromal period of schizophrenia. Even though a protective role of smoking has been reported by one study, other studies report an increased risk for psychosis, with hazard ratios 2.77 (95% CI: 2.34-3.43) and 2.21 (95% CI: 1.11-4.42) for female and male heavy smokers (11-20 and >20 cigarettes/day), respectively. In a different study, the risk of onset was associated with the progressive use of cannabis and tobacco prior to onset, particularly with rapid escalation to the highest levels of use. Also, nicotine use in ultra high risk (UHR) for developing psychosis subjects is associated with elevated cognitive performance, namely better processing speed, visual learning, and spatial working memory. As a conclusion, it appears that evidence accumulates supporting a possible etiologic role of smoking, in the emergence of schizophrenia along with diverse effects on patients' symptomatology, already demonstrable at the prodromal phase. Future research employing better-defined criteria should further explore the patterns of use and effects of nicotine during the schizophrenia prodrome.

RESUMO

Cost- and time-effective markers of Alzheimer's disease (AD), reliable and feasible at the population level are urgently needed. Soluble amyloid-ß protein precursor ß (sAßPPß) in plasma has attracted scientific attention as a potential AD biomarker candidate. Here we report that plasma sAßPPß levels in patients with AD dementia and typical for AD cerebrospinal fluid (CSF) biomarker profiles (N = 33) are significantly lower (p < 0.01) than those of cognitively healthy elderly individuals without AD (N = 39), while CSF sAßPPß levels did not differ between the studied groups. This provides further evidence for the potential of sAßPPß in plasma as an AD biomarker candidate.

RESUMO

Rapid hormonal changes during pregnancy as well as psycho-social stressors accompanying parenthood have often been associated with peripartum mood episodes in women with bipolar disorder or with not yet clinically expressed bipolar diathesis. Yet, little is known about the correlation of peripartum onset of bipolar disorder in men. We present the case of a man with bipolar disorder with peripartum onset and subsequent episodes following the peripartum initiation of the disease, as well as the association of the couvade syndrome, as a pathological response to a man due to hormonal shifts observed in males cohabiting with a pregnant female. The patient had his first depressive episode during the peripartum period of his spouse, followed by two mixed episodes with psychotic features that leaded to his compulsory psychiatric evaluation and subsequent hospitalization and the diagnosis of Bipolar Disorder I. There is a well-known correlation between the peripartum period and mood disturbances to the point of inducing full blown episodes, suggesting of a bipolar disorder initiation or mood episodes relapsing in female patients already diagnosed with bipolar disorder. Due to the patient's psychological disturbances and the phenomenology of his symptoms, mainly concerning the psychotic features accompanying his episodes, we discuss the possible underlying biological correlates as a triggering mechanism, that might overlap the manifestation of the Couvade Syndrome as well as the initiation or relapse of Bipolar Disorder in males. It seems that males are not less influenced by hormonal and psycho-social factors posed upon them during the peripartum period of their cohabiting female spouse.
