RESUMO

Many individuals with serious mental illness are at high risk for hospitalization or death due to inadequate treatment of medical conditions or unhealthy behaviors. The authors describe demographic and clinical characteristics associated with increased risk in this population. Electronic data were obtained for individuals in treatment at a large Veterans' healthcare system who were at high risk according to a validated model. A random sample of these individuals was assessed in person. Multivariable regressions estimated the effect of numerous demographic, health, and clinical characteristics on risk. Emergency visits and hospitalizations were common. Greater risk was associated with being male, not married, and having more diagnoses. While risk varied by race, this effect was no longer significant after controlling for other factors. Health-related quality of life worsened with increasing risk. Routine data identify a large population of high-risk individuals who may benefit from outreach to provide healthcare services.

RESUMO

Evidence shows that caring for a family member with a psychotic disorder generates a significant emotional impact and repercussions on social functioning. However, this caregiving experience can be influenced by cultural factors. The aim of this study is to explore the experience and perception of a group of family caregivers of patients with psychotic disorders of different durations regarding the emotional and social functioning repercussions of caregiving on them in Andalusia. Three focus groups (28 participants) were conducted. Data were subject to a thematic analysis. Three themes emerged from the data: 1) Emotional invasion; 2) Disruption in the caregiver's life project; and 3) Changes in the family system. Participants reported experiencing sadness, fear, overwhelm, hopelessness, and uncertainty. Caregivers' accounts reflected an interruption of their daily tasks, as well as the need to reformulate plans or goals outside the family life that require long-term commitment, such as professional development or even their residence. The narratives indicated an impact on all roles within the family system, particularly for the mother. The results are consistent with existing research. Healthcare professionals and programs should take into account the costs associated with caregiving in order to minimize them, given the impact it has on both the patient's and the caregivers' health.

RESUMO

BACKGROUND: Resilience is defined as the ability to modify thoughts to cope with stressful events. Patients with schizophrenia (SCZ) having higher resilience (HR) levels show less severe symptoms and better real-life functioning. However, the clinical factors contributing to determine resilience levels in patients remain unclear. Thus, based on psychological, historical, clinical and environmental variables, we built a supervised machine learning algorithm to classify patients with HR or lower resilience (LR). METHODS: SCZ from the Italian Network for Research on Psychoses (N = 598 in the Discovery sample, N = 298 in the Validation sample) underwent historical, clinical, psychological, environmental and resilience assessments. A Support Vector Machine algorithm (based on 85 variables extracted from the above-mentioned assessments) was built in the Discovery sample, and replicated in the Validation sample, to classify between HR and LR patients, within a nested, Leave-Site-Out Cross-Validation framework. We then investigated whether algorithm decision scores were associated with the cognitive and clinical characteristics of patients. RESULTS: The algorithm classified patients as HR or LR with a Balanced Accuracy of 74.5% (p < 0.0001) in the Discovery sample, and 80.2% in the Validation sample. Higher self-esteem, larger social network and use of adaptive coping strategies were the variables most frequently chosen by the algorithm to generate decisions. Correlations between algorithm decision scores, socio-cognitive abilities, and symptom severity were significant (pFDR < 0.05). CONCLUSIONS: We identified an accurate, meaningful and generalizable clinical-psychological signature associated with resilience in SCZ. This study delivers relevant information regarding psychological and clinical factors that non-pharmacological interventions could target in schizophrenia.

RESUMO

BACKGROUND: Evidence from treatment trials shows that the most effective pharmacological treatment for Psychotic Major Depression (PMD) is combined antidepressant and antipsychotic pharmacotherapy. AIM: This study investigates the use of antidepressant and antipsychotic treatment for PMD in clinical practice and examines how treatment profiles correlate with demographic and clinical symptoms. METHOD: Anonymised electronic health records of 2,837 individuals with PMD were followed up for 12-months post-diagnosis in a historic open cohort design. The use of antidepressants and antipsychotics, alone or in combination, were described using frequency statistics. Demographic and clinical characteristics associated with each treatment were assessed using logistic regression analyses. RESULTS: Antidepressant and antipsychotic combination pharmacotherapy was the most used treatment for PMD with 69.9% users, compared to antidepressant monotherapy (10.9%) and antipsychotic monotherapy (10.3%). The remaining 8.9% of individuals did not receive antidepressant or antipsychotic treatment. The presence of delusions was strongly associated with the use of antipsychotics, both alone (odds ratio =3.99, 95% confidence intervals = 2.72-5.83, p<.001) and in combination with antidepressants (OR = 2.7, 95% CI = 2.09-3.67, p<.001), rather than antidepressant treatment alone. CONCLUSIONS: Combined antidepressant and antipsychotic pharmacotherapy is the most common treatment of PMD in clinical practice, showing that clinical practice is in line with evidence from treatment research.

RESUMO

Serious and realistic research into the inheritance of the psychoses started in earnest at the beginning of the twentieth century. This was encouraged by both the acceptance of the Kraepelinian classification and the rediscovery of the Mendelian model of inheritance. The application of Mendelian rules to the very complex genetics of the psychoses led to agonizing debate. The Classic Text is a translation of the introduction of the doctoral thesis of Jens Chr. Smith, a little-known Danish psychiatrist who was able to summarize, with the enthusiasm typical to his youth and with surprising accuracy, the early stages of the debate mentioned above.

RESUMO

Expansive autopsychosis, grouped with cycloid psychoses - an illness entity of double origin: (1) Morel's notion degeneracy, reformulated by Magnan and Legrain (reflected in Wimmer's concept: psychogenic psychosis); (2) Wernicke's, Kleist's, Bostroem's (and later Leonhard's) notion of these purportedly independent conditions. Locked in the Danish language, Strömgren and Ostenfeld provided important contributions to this field, exemplified by Ostenfeld's casuistry, translated in this Classic Text.

RESUMO

The negative symptoms of schizophrenia are responsible for patients' worse quality of life. The association with cognitive deficits impairs clinical and psychopathological conditions. Our small 5-year observational study evaluated the efficacy of clozapine in negative and cognitive symptoms in schizophrenia inpatients. The overall results showed a significant improvement in the mean total scores of the BNSS and PANSS (at baseline (T0) vs five years (T3)). The improvement was also in some negative subscales (PANSS Negative Factor subscale) but not in others and the Epitrack tool. The overall results showed that clozapine is a useful therapeutic tool that does not affect the cognitive decline of these patients.

RESUMO

Negative symptoms (NSs) and cognitive deficits (CDs) negatively affect patients' quality of life with primary psychosis. Our observational study evaluated the percentage of NSs in a group of inpatients of a psychiatric rehabilitation facility and the variation of the interaction with CDs during the COVID-19 pandemic. The results showed a significant correlation between NSs and CDs in the first observation period (PANSS - FSNS p=0.001; BNSS p=0.023; Epitrack p=0.00) and a stabilization of the results between the first and second observation periods (PANSS - FSNS: p=0.094; BNSS p=0.466; Epitrack p=0.026).

RESUMO

Low levels of vitamin C have been observed in patients with schizophrenia and psychosis, and vitamin C may affect the dopaminergic system. Likewise, antipsychotic medication modulates striatal dopamine D2 receptors. We measured vitamin C levels in 52 patients with first-episode psychoses (24 females, age 23.1 ± 5.2 years) and 57 matched HCs (20 females, age 22.7 ± 4.3 years) before and after 6 weeks where patients received aripiprazole monotherapy (mean dose 10.4 mg ± 4.8 mg). At baseline, patients displayed lower levels of vitamin C (57.4 ± 25.9 µM) than controls (72.7 ± 21.4 µM) (t = 3.4, P = .001). Baseline symptoms and vitamin C levels were not correlated. Higher baseline vitamin C levels were associated with more improvement in negative symptoms (n = 39, R2 = 0.20, F = 8.2, P = .007), but not with age, sex, or p-aripiprazole. Because negative symptoms are generally considered challenging to alleviate, a potential adjunctive effect of vitamin C on treatment response should be tested in future randomized clinical trials.

RESUMO

OBJECTIVE: To test whether a schizophrenia polygenic risk score (PRS) based on the subset of polymorphisms that affect brain expression of genes with altered expression by antipsychotics (exprAP PRS) is associated with psychiatric readmission of patients with schizophrenia. METHODS: The study involved 427 patients with schizophrenia. Genes with altered expression by antipsychotics were extracted from the Comparative Toxigenomics Database. ExprAP PRS was estimated using the clumping and thresholding (p < 0.05) method. Two additional PRS were tested based on subsets of exprAP polymorphisms whose schizophrenia risk allele has the same (unrestored PRS) or opposite (restored PRS) direction of effect on gene expression than antipsychotics. A general SCZ PRS was tested for comparison. Logistic and ordinal regression were used to test for association of each PRS with ever readmission and admission history, an outcome based on length and number of admissions, respectively. Webgestalt was used for Gene Ontology enrichment analysis. RESULTS: ExprAP PRS was associated with ever readmission (OR = 1.48, 95%CI:1.10-1.97) and admission history (OR = 1.30, 95%CI 1.07-1.57). SCZ PRS (OR = 1.22, 95%CI: 1.01-1.48) and unrestored PRS (OR = 1.26, 95%CI 1.04-1.53) were only associated with admission history. Genes at exprAP PRS were enriched in regulation of cytokine production. CONCLUSION: Our findings suggest that PRS based on genes with altered expression by antipsychotics may be better predictors of readmission than SCZ PRS, warranting further investigation in larger cohorts of patients. The action of antipsychotics may be related to brain gene expression, mainly in genes involved in immunity.

RESUMO

This study aimed to characterize the clinical profile of patients with brief psychotic disorders (BPD) triggered by the psychosocial distress derived from the COVID-19 crisis. A multicenter study was conducted from March 14 to May 14, 2020 (the peak weeks of the pandemic in Europe). All consecutive patients presenting non-affective psychotic episodes with a duration of untreated psychosis of less than 1 month and whose onset was related to the COVID-19 crisis were recruited, but only those patients meeting Diagnostic Statistical Manual 5th edition (DSM-5) criteria for "BPD with marked stressors" (DSM-5 code: 298.8) during follow-up were finally included. Patients' sociodemographic and clinical characteristics were collected at baseline and summarized with descriptive statistics. During the study period, 57 individuals with short-lived psychotic episodes related to the emotional stress of the COVID-19 pandemic were identified, of whom 33 met DSM-5 criteria for "BPD with marked stressors". The mean age was 42.33 ± 14.04 years, the gender distribution was almost the same, and the majority were rated as having good premorbid adjustment. About a quarter of the patients exhibited suicidal symptoms and almost half presented first-rank schizophrenia symptoms. None of them were COVID-19 positive, but in more than half of the cases, the topic of their psychotic features was COVID-19-related. The coronavirus pandemic is triggering a significant number of BPD cases. Their risk of suicidal behavior, their high relapse rate, and their low temporal stability make it necessary to closely monitor these patients over time.

RESUMO

The potentially traumatic impact of the COVID-19 pandemic in subjects with pre-existing mental disorders is still unclear, especially regarding its long-term consequences. The aim of this study was to prospectively assess post-traumatic stress disorder (PTSD) and post-traumatic stress symptoms (PTSS) in patients with mental disorders, during the 3rd wave of the infection (T0, March-April 2021) while strict containment measures were applied in Italy, and after 3 months (T1, June-July 2021), with reduced restrictive measures. A total sample of 527 subjects, with different DSM-5 diagnoses, was consecutively enrolled at nine Italian psychiatric outpatient services. Assessments at T0 included: the Trauma and Loss Spectrum-Self Report (TALS-SR), the Impact of Event Scale-Revised (IES-R) and the Work and Social Adjustment Scale (WSAS). These two latter were repeated at T1. Results showed that at T0, 43.6% of the sample reported symptoms of PTSD, with females (p = .004), younger subjects (p = .011), unemployed/students (p = .011), and living with their parental families (p = .017), resulting more affected. Differences in PTSD rates emerged across diagnostic groups ranging from 10% in patients with psychoses up to 59% in those with feeding and eating disorders. An improvement at T1 emerged in all diagnostic groups for the IES-R scores, while WSAS scores improved only in subjects with mood disorders. In conclusions, subjects with mental disorders presented relevant rates of PTSD and PTSS at 1-year into the pandemic. Further long-term studies are needed to follow-up the course of pandemic traumatic burden especially in patients with severe mental disorders.

RESUMO

OBJECTIVE: A systematic review of literature was conducted to determine the association between serum lipids and suicidality in people with schizophrenia spectrum disorders. METHODS: We undertook a systematic search of multiple databases for studies that ascertained an association between serum lipids and suicidality in adult patients with schizophrenia spectrum disorders (18-65 years) from database inception to 2 September 2020. Qualitative analysis was done using National Institute of Health (NIH) scales. The standard mean difference (SMD) and 95% confidence intervals (CI) were calculated for each study and standardized relative to the study. Adjusted p-value, Z-test, and heterogeneity were calculated, as well as testing for publication bias. RESULTS: Of 1262 records identified, 17 studies (n = 3113) were included in our systematic review, while 11 studies were included in the meta-analysis. The majority of studies (11) rated fair on qualitative analysis. Data from seven studies (n = 1597) revealed a medium effect size for an association between low total cholesterol and suicide attempts (SMD -0.560; 95% CI: 0.949-0.170; p = 0.005). People with history of suicide attempt had a mean cholesterol value 0.56 SD lower than the mean in those without suicide attempts. There were differences in how a suicide attempt was defined and there was high heterogeneity (I2 = 83.3%). No significant association was found between any of the serum lipid parameters and suicide ideation. Funnel-plot analysis suggested small study effects with publication bias. CONCLUSIONS: Suicide attempts in people with schizophrenia spectrum disorders are associated with low mean total cholesterol levels.

RESUMO

INTRODUCTION: The aim of this study is to analyse different ways of participation during the development of a clinical guideline to improve the early detection of psychosis and to deploy a comprehensive treatment plan to improve prognosis and social integration. MATERIALS AND METHOD: The clinical guideline was developed using the ADAPTE method with the participation of 40 authors and 80 external reviewers. The process was divided into three major phases: set up, adaptation and finalization. During adaptation and completion, a total of 44 patients and 18 family caregivers were involved. RESULTS AND CONCLUSIONS: The different roles assumed by the patients and their family caregivers were described, depending on the panel in which they participated, with diverse grades of complexity: a user as author, integration of the results of qualitative research with the participation of local users and family caregivers, 13 users as individual external reviewers and the participation of users and caregiver organizations in the external review. In the guideline, contributions from patients during the qualitative research were included in an innovative way, placing them just behind the recommendations. On the other hand, the results of the family caregivers' study were included in a specific area of uncertainty. Further, the expressed point of view was considered as the collective demands of users and family caregivers' organizations in the cost-benefit analysis made by the organizing committee. There were diverse ways to conduct direct patient participation during the guideline development, ensuring that their individual experiences contributed significantly to the final version.

RESUMO

BACKGROUND: Effects of drug treatment of clinical Alzheimer-type dementia (CATD) are uncertain. PURPOSE: To summarize evidence on the effects of prescription drugs and supplements for CATD treatment. DATA SOURCES: Electronic bibliographic databases (inception to November 2019), ClinicalTrials.gov (to November 2019), and systematic review bibliographies. STUDY SELECTION: English-language trials of prescription drug and supplement treatment in older adults with CATD that report cognition, function, global measures, behavioral and psychological symptoms of dementia (BPSD), or harms. Minimum treatment was 24 weeks (≥2 weeks for selected BPSD). DATA EXTRACTION: Studies with low or medium risk of bias (ROB) were analyzed. Two reviewers rated ROB. One reviewer extracted data; another verified extraction accuracy. DATA SYNTHESIS: Fifty-five studies reporting non-BPSD outcomes (most ≤26 weeks) and 12 reporting BPSD (most ≤12 weeks) were analyzed. Across CATD severity, mostly low-strength evidence suggested that, compared with placebo, cholinesterase inhibitors produced small average improvements in cognition (median standardized mean difference [SMD], 0.30 [range, 0.24 to 0.52]), no difference to small improvement in function (median SMD, 0.19 [range, -0.10 to 0.22]), no difference in the likelihood of at least moderate improvement in global clinical impression (median absolute risk difference, 4% [range, 2% to 4%]), and increased withdrawals due to adverse events. In adults with moderate to severe CATD receiving cholinesterase inhibitors, low- to insufficient-strength evidence suggested that, compared with placebo, add-on memantine inconsistently improved cognition and improved global clinical impression but not function. Evidence was mostly insufficient about prescription drugs for BPSD and about supplements for all outcomes. LIMITATION: Most drugs had few trials without high ROB, especially for supplements, active drug comparisons, BPSD, and longer trials. CONCLUSION: Cholinesterase inhibitors and memantine slightly reduced short-term cognitive decline, and cholinesterase inhibitors slightly reduced reported functional decline, but differences versus placebo were of uncertain clinical importance. Evidence was mostly insufficient on drug treatment of BPSD and on supplements for all outcomes. PRIMARY FUNDING SOURCE: Agency for Healthcare Research and Quality. (PROSPERO: CRD42018117897).

RESUMO

PURPOSE: Service providers need effective strategies to implement evidence-based practices (EBPs) with high fidelity. This study aimed to evaluate an intensive implementation support strategy to increase fidelity to EBP standards in treatment of patients with psychosis. METHODS: The study used a cluster randomized design with pairwise assignment of practices within each of 39 Norwegian mental health clinics. Each site chose two of four practices for implementation: physical health care, antipsychotic medication management, family psychoeducation, illness management and recovery. One practice was assigned to the experimental condition (toolkits, clinical training, implementation facilitation, data-based feedback) and the other to the control condition (manual only). The outcome measure was fidelity to the EBP, measured at baseline and after 6, 12, and 18 months, analyzed using linear mixed models and effect sizes. RESULTS: The increase in fidelity scores (within a range 1-5) from baseline to 18 months was significantly greater for experimental sites than for control sites for the combined four practices, with mean difference in change of 0.86 with 95% CI (0.21; 1.50), p = 0.009). Effect sizes for increase in group difference of mean fidelity scores were 2.24 for illness management and recovery, 0.68 for physical health care, 0.71 for antipsychotic medication management, and 0.27 for family psychoeducation. Most improvements occurred during the first 12 months. CONCLUSIONS: Intensive implementation strategies (toolkits, clinical training, implementation facilitation, data-based feedback) over 12 months can facilitate the implementation of EBPs for psychosis treatment. The approach may be more effective for some practices than for others.

RESUMO

Cortical thickness (CT) and local gyrification index (LGI) in psychotic disorders may show modifications that relate to clinical course. This observational study aimed to analyse such variables in patients with schizophrenia, compared to healthy controls (HCs). We compared CT and LGI of 18 patients with first-episode psychosis with that of 21 with multi-episode schizophrenia and 16 HCs. CT corrected for false-positive cases (Family-Wise Error Rate) showed a reduction in the multi-episode group compared to HCs in left temporal and parietal, and right temporal, parietal, occipital, and hippocampal cortices. Family-wise corrected LGI was increased in the left inferior and middle frontal cortices, and in the right fusiform gyrus, cingulate, lingual, and parahippocampal gyri in first onset patients compared to HCs. Increased LGI was absent from later stages of psychosis, suggesting that specific CT and LGI alterations may underlie different stages of illness.

RESUMO

Periodic catatonia (PC) is a psychomotor phenotype with a progressive-remitting course. While it can fit any disorder diagnosis of the schizoaffective spectrum, its core features consist of a mix of hypo- and hyperkinesias resulting in distortions of expressive movements such as grimacing and parakinesias. The replication of cerebral blood flow (CBF) increases in the left supplementary motor area (L-SMA) and lateral premotor cortex (L-LPM) in acute and remitting PC patients indicates that these increases could be used as diagnostic biomarkers. In this proof-of-concept study, 2 different MRI sequences were repeated on 3 separate days to get reliable measurement values of CBF in 9 PC and 26 non-PC patients during different cognitive tasks. Each patient was compared to 37 controls. In L-SMA [-9; +10; +60] and L-LPM [-46; -12; +43], a test was positive if the t value was >2.02 (α < 0.05; two tailed). The measurements had good analytical performance. Regarding the tests, their sensitivities and specificities were significantly different from the chance level on both measures, except for L-SMA sensitivities. When combining all the tests, among regions and methods, sensitivity was 98% (95% credible interval [CI] 76-100%) and specificity 88% (72-97%). Bayesian inferences of its negative predictive values for PC were >95% regardless of the context, while its positive predictive values reached 94% but only when used in combination with clinical criteria. The case-by-case analysis suggests that non-PC patients with neurological motor deficits are at risk to be false positive.

RESUMO

Research showing that risk for schizophrenia, bipolar disorder with psychosis, and other psychosis-spectrum diagnoses in adulthood is multidetermined has underscored the necessity of studying the additive and interactive factors in childhood that precede and predict future disorders. In this study, risk for the development of psychosis-spectrum disorders was examined in a 2-generation, 30-year prospective longitudinal study of 3,905 urban families against a sociocultural backdrop of changing economic and social conditions. Peer nominations of aggression, withdrawal, and likeability and national census information on neighborhood-level socioeconomic disadvantage in childhood, as well as changes in neighborhood socioeconomic conditions over the lifespan, were examined as predictors of diagnoses of schizophrenia, bipolar disorder, and other psychosis-spectrum disorders in adulthood relative to developing only nonpsychotic disorders or no psychiatric disorders. Individuals who were both highly aggressive and highly withdrawn were at greater risk for other psychosis-spectrum diagnoses when they experienced greater neighborhood disadvantage in childhood or worsening neighborhood conditions over maturation. Males who were highly aggressive but low on withdrawal were at greater risk for schizophrenia diagnoses. Childhood neighborhood disadvantage predicted both schizophrenia and bipolar diagnoses, regardless of childhood social behavior. Results provided strong support for multiple-domain models of psychopathology, and suggest that universal preventive interventions and social policies aimed at improving neighborhood conditions may be particularly important for decreasing the prevalence of psychosis-spectrum diagnoses in the future.

The recovery movement has revealed that outcomes which focuses on just symptoms and functioning may not be holistic and that consumer-rated outcomes may contribute to a more holistic and person-centric care model. However, a brief and effective measure is required in clinical settings; hence, the aim of the current study is to evaluate the psychometric properties of the briefest personal recovery measure- Mental Health Recovery Measure-10 items, using the CHIME (Connectedness, Hope and optimism about the future, Identity, Meaning in life, Empowerment) personal recovery framework. 64 outpatients with schizophrenia or schizoaffective disorder were assessed at two time points, 2 weeks apart. Data collected included sociodemographic information, MHRM-10, Psychological factors related to the CHIME framework, in respective order: RYFF subscale positive relations with others; Herth Hope Index (HHI); Internalized Stigma of Mental Illness (ISMI) and RYFF subscale self-acceptance; World Health Organization Quality of Life- BRIEF (WHOQOL-BREF); Empowerment, and Clinical factors- symptoms as measured by Positive and Negative Syndrome Scale, functioning (PSP) and depressive symptoms (CDSS). MHRM-10 demonstrated convergent validity with CHIME personal recovery psychological factors (all ρ > 0.5). MHRM-10 had excellent internal consistency (Cronbach's alpha = 0.904) and adequate test-retest reliability (ρ = 0.742, p < 0.001). Initial factor structure analysis revealed a one factor structure. The MHRM-10 is a valid instrument for use and can serve as a tool to facilitate a more collaborative and person-centric model of care for individuals with psychosis.
