RESUMEN

ABSTRACT: To our knowledge, this is the first study that specifically aims to assess the readability and quality of online information about schizophrenia. The analysis is performed on 93 of 195 websites that appeared in an advanced Google search of the term "schizophrenia" performed on a single day. The websites were categorized as commercial, nonprofit, professional, and government. The websites were evaluated using the Health on the Net Foundation (HON) code certificate, DISCERN tool, and Journal of the American Medical Association ( JAMA ) benchmark criteria for quality and the Flesch Reading Ease Formula, Flesch-Kincaid Grade Level (FKGL) Formula, Simple Measure of Gobbledygook, and Gunning Fog indices for readability. A total of 21.5% of all websites had a HON code certificate, 50.5% were accepted as high quality ( JAMA score ≥3), and 25.8% reached the recommended readability level (FKGL ≤8). Only three websites scored at a fifth- to sixth-grade reading level. Commercial and government websites had significantly lower DISCERN scores. Commercial websites had significantly lower Flesch Reading Ease Score and FKGL score than nonprofit websites. In conclusion, the current findings indicate that the quality of online information on schizophrenia is generally acceptable, but the readability is insufficient. Website creators, physicians, and health authorities should be more sensitive to the readability of online information about schizophrenia, considering the poor cognitive capacity of the patients and the unique nature of the disease.

RESUMEN

OBJECTIVES: The Internet is now more widely used than before by psychiatric patients and their families to search for medical conditions and treatments. To our knowledge, no study has addressed the quality and readability of online information about electroconvulsive therapy (ECT). We aimed to examine the quality and readability of English-language Internet information related to ECT. METHODS: An advanced search of Internet Web sites containing information about ECT was conducted by using the search term "ECT or electroconvulsive therapy." The resulting Web sites were categorized into 1 of 3 categories (commercial, nonprofit, or professional organizations). Their quality was evaluated using Health on the Net code certification, the Journal of the American Medical Association (JAMA) benchmark criteria, and the DISCERN tool. The readability of the Web sites was assessed using the Flesch Reading Ease, Flesch-Kincaid Grade Level Formula, Simple Measure of Gobbledygook, and Gunning Fog indexes. RESULTS: A total of 86 Web sites were included in the analysis. Of all these Web sites, 18 (20.9%) had a Health on the Net code certificate, and 16 (18.6%) were accepted as high quality (JAMA total score ≥3). The commercial Web sites had significantly lower DISCERN and JAMA benchmark scores compared with the other Web sites. A total of 30.23% of all the Web sites reached the recommended readability level (Flesch-Kincaid Grade Level Formula ≤ 8). Moreover, only 4 scored at the grade 5 to 6 reading level, which is considered ideal for patient educational materials. CONCLUSIONS: Our study indicates that both the quality and readability of online information about ECT are not at the desired level. Physicians, patients, and their families should consider this failure in relation to online information about ECT. In addition, Web site creators and health authorities should be aware of their responsibilities for providing quality and readable health information to the public.

RESUMEN

Molecular tumor boards (MTBs) require specialized activities to leverage genomic data for therapeutic decision-making. Currently, there are no defined standards for implementing, executing, and tracking the impact of MTBs. This study describes the development and validation of ACTE-MTB, a tool to evaluate the maturity of an organization's MTB to identify specific areas that would benefit from process improvements and standardization. The ACTE-MTB maturity assessment tool is composed of 3 elements: 1) The ACTE-MTB maturity model; 2) a 59-question survey on MTB processes and challenges; and 3) a 5-level MTB maturity scoring algorithm. This tool was developed to measure MTB maturity in the categories of Access, Consultation, Technology, and Evidence (ACTE) and was tested on 20 MTBs spanning the United States, Europe, and Asia-Pacific regions. Validity testing revealed that the average maturity score was 3.3 out of 5 (+/- 0.1; range 2.0-4.3) with MTBs in academic institutions showing significantly higher overall maturity levels than in non-academic institutions (3.7 +/- 0.2 vs. 3.1 +/- 0.2; P = .018). While maturity scores for academic institutions were higher for Consultation, Technology, and Evidence domains, the maturity score for the Access domain did not significantly differ between the two groups, highlighting a disconnect between MTB operations and the downstream impact on ability to access testing and/or therapies. To our knowledge, ACTE-MTB is the first tool of its kind to enable structured, maturity assessment of MTBs in a universally-applicable manner. In the process of establishing construct validity of this tool, opportunities for further investigation and improvements were identified that address the key functional areas of MTBs that would likely benefit from standardization and best practice recommendations. We believe a unified approach to assessment of MTB maturity will help to identify areas for improvement at both the organizational and system level.

RESUMEN

There is a growing need for alternative methodologies to evaluate digital health solutions in a short timeframe and at relatively low cost. Simulation-based research (SBR) methods have been proposed as an alternative methodology for evaluating digital health solutions; however, few studies have described the applicability of SBR methods to evaluate such solutions. This study used SBR to evaluate the feasibility and user experience of a clinical decision support (CDS) tool used for matching cancer patients to clinical trials. Twenty-five clinicians and research staff were recruited to match 10 synthetic patient cases to clinical trials using both the CDS tool and publicly available online trial databases. Participants were significantly more likely to report having sufficient time (p = 0.020) and to require less mental effort (p = 0.001) to complete trial matching with the CDS tool. Participants required less time for trial matching using the CDS tool, but the difference was not significant (p = 0.093). Most participants reported that they had sufficient guidance to participate in the simulations (96%). This study demonstrates the use of SBR methods is a feasible approach to evaluate digital health solutions and to collect valuable user feedback without the need for implementation in clinical practice. Further research is required to demonstrate the feasibility of using SBR to conduct remote evaluations of digital health solutions.

RESUMEN

ABSTRACT: We aimed to explore the prevalence and determinants of severe COVID-19 disease and mortality in patients with schizophrenia in this study. We conducted a retrospective observational study of 1620 patients with schizophrenia. Of the 1620 patients, 52 (3.2%) tested positive for SARS-CoV-19. Among SARS-CoV-2-positive patients, 40 patients were hospitalized, and 17 patients required intensive care unit admission due to COVID-19 (76.9% and 32.7%, respectively). Severe COVID-19 disease was noted in 17 patients (32.7%) requiring intubation. In the logistic regression analysis, antipsychotic dose, and comorbidity score were independently associated with a greater risk of severe COVID-19 disease in patients with schizophrenia. Our study suggests that factors such as age, sex, comorbidities, and a daily antipsychotic dose may have effects on the poor outcome of SARS-CoV-2 disease in schizophrenia patients. In addition, the current findings propose that mortality may be associated with an older age, comorbidity score, and a longer duration of psychiatric disease among the SARS-CoV-2-positive patients with schizophrenia. However, the findings of our study should be verified in prospective and larger sample studies.

RESUMEN

This study aims to examine possible differences in the effect on the course characteristics of the disease in cases of no use, short-term use and long-term use of benzodiazepines in patients with schizophrenia. In this retrospective observational study, the sample comprised patients with schizophrenia who were admitted to our psychiatric clinics from January 2015 to January 2019. Patients were also retrospectively tracked from the date of the first admission during the specified time until the end of the observation period (24 months) for clinical course characteristics. Data for 1710 patients with schizophrenia were included in the analyses. Patients with short-term benzodiazepines use had fewer psychiatric hospitalizations and shorter lengths of stay at psychiatric services than patients with no use or long-term use. Rates of antipsychotic drug discontinuation and suicidal behavior were also significantly lower among short-term benzodiazepines users than among those with no use or long-term use. In conclusion, our study indicates that short-term benzodiazepines use is associated with a better clinical course in patients with schizophrenia. Future studies should evaluate the effects of different benzodiazepines use patterns on disease prognosis with longer-term follow-up and prospective methodology and should concomitantly examine psychopathological variables.

RESUMEN

Tic-related obsessive-compulsive disorder (OCD) may be a unique OCD subtype. This study examined whether neurological soft signs (NSSs) of patients with tic-related and tic-free OCD enable discrimination of these subgroups. We used the Neurological Evaluation Scale to assess 32 patients with tic-related and 94 with tic-free OCD, as well as 84 controls. Most patients with tic-related OCD were male, with earlier illness onset and poorer insight scores than those of patients with tic-free OCD. Patients with tic-related OCD had poorer motor coordination, sensory integration, and motor sequencing than did tic-free patients. Logistic regression using NSS subscale scores predicted tic-related OCD. Patients with tic-related OCD displayed greater neurodevelopmental abnormalities than did tic-free patients. NSSs of the former group suggest the need to separate this subgroup. Our results also support the newly introduced tic-related specifier in the fifth edition of the Diagnostic and statistical manual of mental disorders.

RESUMEN

OBJECTIVES: The aim of this study was to analyze whether scar characterization could improve the risk stratification for life-threatening ventricular arrhythmias and sudden cardiac death (SCD). BACKGROUND: Among patients with a cardiac resynchronization therapy (CRT) indication, appropriate defibrillator (CRT-D) therapy rates are low. METHODS: Primary prevention patients with a class I indication for CRT were prospectively enrolled and assigned to CRT-D or CRT pacemaker according to physician's criteria. Pre-procedure contrast-enhanced cardiac magnetic resonance was obtained and analyzed to identify scar presence or absence, quantify the amount of core and border zone (BZ), and depict BZ distribution. The presence, mass, and characteristics of BZ channels in the scar were recorded. The primary endpoint was appropriate defibrillator therapy or SCD. RESULTS: 217 patients (39.6% ischemic) were included. During a median follow-up of 35.5 months (12 to 62 months), the primary endpoint occurred in 25 patients (11.5%) and did not occur in patients without myocardial scar. Among patients with scar (n = 125, 57.6%), those with implantable cardioverter-defibrillator (ICD) therapies or SCD exhibited greater scar mass (38.7 ± 34.2 g vs. 17.9 ± 17.2 g; p < 0.001), scar heterogeneity (BZ mass/scar mass ratio) (49.5 ± 13.0 vs. 40.1 ± 21.7; p = 0.044), and BZ channel mass (3.6 ± 3.0 g vs. 1.8 ± 3.4 g; p = 0.018). BZ mass (hazard ratio: 1.06 [95% confidence interval: 1.04 to 1.08]; p < 0.001) and BZ channel mass (hazard ratio: 1.21 [95% confidence interval: 1.10 to 1.32]; p < 0.001) were the strongest predictors of the primary endpoint. An algorithm based on scar mass and the absence of BZ channels identified 148 patients (68.2%) without ICD therapy/SCD during follow-up with a 100% negative predictive value. CONCLUSIONS: The presence, extension, heterogeneity, and qualitative distribution of BZ tissue of myocardial scar independently predict appropriate ICD therapies and SCD in CRT patients.

RESUMEN

BACKGROUND: Schizophrenia is a chronic and debilitating mental disorder that affects the patient's and their family's life. The disease remains a complicated disorder that is challenging to treat, despite there being a large antipsychotic armamentarium. Brexpiprazole acts both as a partial agonist at the serotonin 5-HT1A and dopamine D2 receptors and as an antagonist at the serotonin 5- HT2A and noradrenaline alpha1B and alpha2C receptors, all with similar potency. This balanced receptor profile may produce promising antipsychotic effects on positive, negative and cognitive symptoms in schizophrenia with minimal adverse effects. METHODS: This review summarizes the pharmacodynamics and pharmacokinetic profile of brexpiprazole and the clinical trial information pertaining to its effectiveness and safety and tolerability, discusses its best clinical use, and compares its clinical profile to those of other widely used antipsychotic agents. RESULTS: Brexpiprazole demonstrated significant clinical efficacy and had good safety and tolerability in well-designed trials with patients with schizophrenia. This agent may be a useful treatment alternative. CONCLUSION: However, it will be valuable to consider a long-term observational study that includes an active comparator, especially other second-generation antipsychotics (SGAs), to further evaluate the efficacy and safety of brexpiprazole in the treatment of schizophrenia.

RESUMEN

The diagnostic evaluation of acute chest pain has been augmented in recent years by advances in the sensitivity and precision of cardiac troponin assays, new biomarkers, improvements in imaging modalities, and release of new clinical decision algorithms. This progress has enabled physicians to diagnose or rule-out acute myocardial infarction earlier after the initial patient presentation, usually in emergency department settings, which may facilitate prompt initiation of evidence-based treatments, investigation of alternative diagnoses for chest pain, or discharge, and permit better utilization of healthcare resources. A non-trivial proportion of patients fall in an indeterminate category according to rule-out algorithms, and minimal evidence-based guidance exists for the optimal evaluation, monitoring, and treatment of these patients. The Cardiovascular Round Table of the ESC proposes approaches for the optimal application of early strategies in clinical practice to improve patient care following the review of recent advances in the early diagnosis of acute coronary syndrome. The following specific 'indeterminate' patient categories were considered: (i) patients with symptoms and high-sensitivity cardiac troponin <99th percentile; (ii) patients with symptoms and high-sensitivity troponin <99th percentile but above the limit of detection; (iii) patients with symptoms and high-sensitivity troponin >99th percentile but without dynamic change; and (iv) patients with symptoms and high-sensitivity troponin >99th percentile and dynamic change but without coronary plaque rupture/erosion/dissection. Definitive evidence is currently lacking to manage these patients whose early diagnosis is 'indeterminate' and these areas of uncertainty should be assigned a high priority for research.

RESUMEN

OBJECTIVES: The role of inflammation and lipid metabolism in the pathophysiology of suicidal behavior has received particular attention in recent years. The neutrophil-to-lymphocyte ratio (NLR) has been suggested as a new and more reliable indicator of low-grade inflammation. NLR has been found to be altered in major depressive disorder (MDD) and has been related to various factors, including chronic stress and impulsivity that were previously reported to be related to suicidal behavior. We aimed to explore the roles of NLR, C-reactive protein (CRP) and serum lipid levels on suicidal behavior in patients with MDD. METHODS: The study group consisted of 139 inpatients diagnosed with MDD [37 suicide attempters (SA); 102 suicide non-attempters (NSA)], 50 healthy controls and matched according to age, gender and education. NLR, PLR, CRP and lipid values were obtained from digital inpatient records. RESULTS: CRP levels and NLR were substantially higher in patients with SA than in subjects with NSA and healthy comparison subjects after adjusting the confounding factors. The logistic regression included two predictive variables for suicide status in patients with depressive disorder (A) previous suicidal history; (B) NLR. CONCLUSIONS: This is the first study suggesting that NLR may be a trait marker for suicidal vulnerability via a relationship between NLR and a recent suicide attempt in depressed inpatients. Future prospective studies are needed to determine the exact roles of NLR, and other inflammatory markers on suicidality in MDD.

RESUMEN

BACKGROUND: Predicting sudden cardiac death risk in the first months after ST-segment elevation myocardial infarction (STEMI) remains challenging. OBJECTIVE: The purpose of this study was to investigate the ability of late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) to identify the potentially arrhythmogenic substrate and its temporal evolution after STEMI. METHODS: One hundred consecutive patients with a first STEMI were included. Three-dimensional high-resolution LGE-CMR was obtained at 3 T on days 7 and 180. Left ventricular wall was segmented and characterized by pixel signal intensity algorithm in 5 layers from endocardium to epicardium. A 3-dimensional color-coded shell map was obtained for each layer, depicting scar core and border zone (BZ) distribution. Presence and characteristics of BZ channels were registered for each layer. RESULTS: At 180 days, left ventricular ejection fraction had improved significantly (from 46.7% ± 10% to 51.5% ± 10%; P <.001) and scar mass was reduced (from 22.6 ± 20 g to 13.8 ± 12 g; P <.001). Most BZ channels (89%) were identified in the same myocardial layer and American Heart Association (AHA) segment, with the same orientation and morphology in both studies. Early LGE-CMR had 96% sensitivity and 90% specificity for predicting presence of BZ channels at 180 days. Greater presence was observed in patients with no-reflow phenomenon at baseline (P = .01). CONCLUSION: Most BZ channels can be identified by LGE-CMR at day 7 post-STEMI and, despite scar mass reduction, remain unaltered at 6 months, suggesting that the potentially arrhythmogenic substrate is established within the first week post-STEMI.

RESUMEN

BACKGROUND: Cognitive insight, a recently developed insight measure, refers to metacognitive processes of the re-evaluation and correction of distorted beliefs and misinterpretations. However, to the best of the authors' knowledge, no study has specifically examined cognitive insight, demographics, psychopathological variables, and distorted beliefs in OCD. AIM: The aim of this research was to examine links between cognitive insight and demographics, clinical factors, and distorted beliefs among patients with OCD. METHOD: Eighty-four consecutive outpatients with a diagnosis of OCD underwent a detailed clinical assessment for OCD, including the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Beck Cognitive Insight Scale (BCIS), Thought-Action Fusion Scale (TAFS), White Bear Thought Suppression Inventory, Metacognition Questioniarre-30 (MCQ-30), and a sociodemographic questionnaire. In addition, 82 control subjects matched for age, education, and gender were tested. RESULTS: BCIS-self-certainty scores were all substantially higher in subjects with remitted and unremitted OCD than in healthy comparison subjects, while BCIS-composite scores were significantly lower in both patient groups than controls. Obsession and compulsion severity had significant effects on BCIS scores. In addition, it was found that the specific symptoms were linked to self-certainty scores. Self-reflectiveness and composite scores had positive correlations with the sub-scale scores of the MCQ-30, while the TAF-morality score was positively correlated with self-certainty scores. CONCLUSION: The results demonstrated poor cognitive insight among remitted and unremitted OCD patients. In addition, the present study suggested significant associations between sociodemographic and clinical features and dysfunctional appraisals. Cognitive-behavioural techniques aimed at enhancing cognitive insight may be beneficial for patients with OCD, particularly patients who have prominent dysfunctional beliefs.

RESUMEN

BACKGROUND: Violence is a significant clinical and public concern and is a frequent occurrence in patients with schizophrenia. The relationship between insight and violence remains controversial. In addition, there is a lack of research on insight, cognitive insight, demographic and psychopathologic variables in violent versus nonviolent schizophrenia patients. AIM: We aimed to compare insight, cognitive insight, psychopathological and demographic variables in violent and nonviolent subjects suffering from schizophrenia. In addition, we aimed to determine the demographic and clinical predictors of violent behaviour in patients with schizophrenia. METHOD: We recruited 133 schizophrenic patients without concomitant substance abuse or axis II disorder. Diagnoses were based on the SCID-I and SCID-II. Violent behaviours were assessed using the Overt Aggression Scale. Insight and cognitive insight were assessed with the Scale to Assess Unawareness of Mental Disorder and the Beck Cognitive Insight Scale, respectively. RESULTS: We compared 47 patients with violent schizophrenia with 86 nonviolent patients. Non-violent patients had more severe depression, lower scores on positive symptoms, better clinical insight, more self-reflectivity and higher R-C index scores than did violent patients. In addition, history of violence, lower self-reflectiveness, worse clinical insight and delusion severity were significant predictors of violence in schizophrenia. CONCLUSION: The present study suggests that the inclusion of insight and cognitive insight may increase the prediction of violence in this population. In addition, clinicians should consider using non-pharmacological techniques that are based on cognitive behaviour therapy and enhance insight, particularly cognitive insight, among patients with schizophrenia who exhibit violent behaviour.

RESUMEN

INTRODUCTION: Schizophrenia is associated with a significant risk of suicide, and suicide still remains one of the main causes of death in schizophrenic patients. Beside classic risk factors for suicidality, temperament and character traits have been researched and considered as risk factors for suicidal behavior in recent years. METHOD: Subjects were 94 patients with schizophrenia who were under treatment. All patients were in a stable phase of the illness. Patients with lifetime suicide attempt (n = 46) and without suicidal attempt (n = 48) were compared with each other in terms of temperament and character traits by using the Temperament and Character Inventory. RESULTS: Harm avoidance and persistence scores were higher in suicidal schizophrenic patients compared with nonsuicidal schizophrenic patients. The scores of self-directedness and cooperativeness were lower in suicidal schizophrenic patients compared with nonsuicidal schizophrenic patients. These 4 variables remained significant predictors of lifetime suicidal attempts in a logistic regression model. CONCLUSION: To the best of our knowledge, the present study is the first that specifically compares schizophrenic patients with and without suicidal behavior by the Cloninger temperament and character model. Our data indicate that schizophrenic patients will show a greater risk for suicide according to certain personality configurations. However, to establish causal relationships between personality and suicidality in schizophrenia, longitudinal studies are warranted within a multifactorial interactive framework of biologic and clinical variables.

RESUMEN

OBJECTIVE: The purpose of this study was to examine personality traits of patients with major depressive disorder and explore the possible connections between personality and clinical and sociodemographic variables. METHODS: The sociodemographic and clinical properties of 80 patients with major depression, who were euthymic according to Hamilton Depression Scale scores, were recorded. Their personality was evaluated by using Temperament and Character Inventory and results were compared with 80 age- and sex-matched healthy controls. We used general linear model analysis to evaluate the manner in which the variables contributed to TCI scores. RESULTS: Remitted depressive patients scored significantly lower on on self-directedness and higher on harm avoidance than HC. Previous suicide attempts had a main effect only on harm avoidance while previous psychotic mood episodes were significantly associated with novelty seeking, self-directedness and cooperativeness. With respect to numeric clinical variables, only duration of illness was significantly and negatively correlated with NS and RD scores. CONCLUSION: Patients with euthymic major depressive disorder may have significantly different personality traits than the normal population, and patients with different clinical and sociodemographic characteristics may show different personality patterns. In addition, assessment of major depressed patients by means of the Temperament and Character Inventory may be helpful to get a deeper insight into those personality traits underlying suicidality and the emergence of psychotic mood episode.

RESUMEN

Patients with deficit schizophrenia have worse cognition and poorer social functioning compared with those with nondeficit schizophrenia. Insight is another domain in which these two groups might differ. However, there is no literature data specifically on cognitive insight impairment in deficit versus nondeficit schizophrenia. We compared 40 patients with deficit schizophrenia with 81 nondeficit patients and found that schizophrenic patients with deficit syndrome were more self-reflective and have higher self-reflectiveness-self-certainty index scores than did those without deficit syndrome. These differences remained significant when analysis was controlled for sex, age, education, and depression severity. On the other hand, there was no significant difference in self-certainty scores between two groups. In addition, we found significant relationships between cognitive insight and specific psychotic symptoms. A better understanding of the cognitive component of insight in schizophrenia with deficit syndrome may help us to understand the true relationship between insight and negative symptoms and contribute to the development of more efficient cognitive strategies, thus improving patients' outcome in a severely disabled psychiatric patient group.

RESUMEN

Despite comorbid depression being relatively common even in subjects with schizophrenia, to the best of our knowledge, there is, to date, no report in the literature specifically and detailed examining the cognitive and clinical insight in subjects with schizophrenia and a comorbid depressive syndrome. Hence, in this study, we sought to compare the cognitive and clinical insight in our subjects with schizophrenia with and without a comorbid depressive syndrome. We found that participants in the depressive group scored significantly higher on self-reflectiveness and the reflectiveness-certainty (R-C) index scores than those in the nondepressive group. There was no significant difference among groups on the Scale for the Assessment of Positive Symptoms, Scale for the Assessment of Negative Symptoms, and clinical insight scores assessed by the Scale to Assess Unawareness of Mental Disorder. In addition, self-reflectiveness scores significantly correlated with depression, observed depression, hopelessness, and suicidality subscores of the Calgary Depression Scale for Schizophrenia. A better understanding of the cognitive component of insight in schizophrenia with comorbid depression may contribute to develop more efficient cognitive strategies, thus improving patient outcome. However, clinicians should be aware of the possibility of exacerbating a sense of hopelessness and suicide risk during the interventions that improve cognitive insight.
