Suicide-related thoughts and behavior and suicide death trends during the COVID-19 in the general population of Catalonia, Spain.

The COVID-19 pandemic is expected to increase suicidal behavior. However, data available to date are inconsistent. This study examines suicidal thoughts and behaviors and suicide trends in 2020 relative to 2019 as an approximation to the impact of the pandemic on suicidal behavior and death in the general population of Catalonia, Spain. Data on suicide-related thoughts and behaviors (STBs) and suicidal mortality were obtained from the Catalonia Suicide Risk Code (CSRC) register and the regional police, respectively. We compared the monthly crude incidence of STBs and suicide mortality rates of 2020 with those of 2019. Joinpoint regression analysis was used to assess changes in trends over time during the studied period. In 2020, 4,263 consultations for STBs and 555 suicide deaths were registered in Catalonia (approx. 7.5 million inhabitants). Compared to 2019, in 2020 STBs rates decreased an average of 6.3% (incidence rate ratio, IRR=0.94, 95% CI 0,90-0,98) and overall suicide death rates increased 1.2% (IRR=1.01, 95% CI 0.90-1.13). Joinpoint regression results showed a substantial decrease in STBs rates with a monthly percent change (MPC) of -22.1 (95% CI: -41.1, 2.9) from January-April 2020, followed by a similar increase from April-July 2020 (MPC=24.7, 95% CI: -5.9, 65.2). The most restrictive measures implemented in response to the COVID-19 pandemic reduced consultations for STBs, suggesting that the "stay at home" message may have discouraged people from contacting mental health services. STBs and mortality should continue to be monitored in 2021 and beyond to understand better the mid-to-long term impact of COVID-19 on suicide trends.

Spanish translation and analysis of the metric properties of inpatient satisfaction scale in psychiatry: The Satispsy-22-E.

The Satispsy-22 scale is an instrument created for the specific evaluation of psychiatric inpatient satisfaction. Therefore, the study aims to carry out the Satispsy-22 scientific translation to Spanish and to learn its psychometric properties. The Satipsy-22-E was administered to discharged patients from four units of acute psychiatric admission, a unit of dual pathology and two units of subacute psychiatric admission (N = 268). Cronbach's alpha was 0.886, which can be interpreted as good internal reliability. All the dimensions showed a good internal consistency with scores from 0.722 to 0.919. Test-retest offered scores of 0.752-0.951 showing good stability. Confirmatory factor analysis showed that all elements load in the estimated dimensions of the original scale and these were significant and the adjustment measures showed, in general, a rather good adjustment, Root Mean Square Error (RMSE) showed that the error between observations and actual data is small and acceptable. Satispsy-22-E is a specific scale in Spanish language for the assessment of psychiatric inpatient satisfaction. It is an easy to use tool that offers good psychometric properties. The availability of a validated survey in Spanish may help to improve the care provided by psychiatric wards in Spanish-speaking countries.

A study on the bioequivalence of lithium and valproate salivary and blood levels in the treatment of bipolar disorder.

Lithium (Li) and valproate (VPA) are used in the treatment of bipolar disorder (BD), with narrow therapeutic window requiring periodic control of serum levels. This prevents intoxication, lack of efficacy due to low serum concentrations, and allows monitoring adherence. We aimed at evaluating the bioequivalence of salivary and blood levels of LI or VPA in a sample of adult BD patients. Secondarily, lithium bioequivalence was evaluated across different patients' lifespans. BD patients treated with either Li or VPA underwent contemporary standard serum and salivary measurements. Blood levels of both drugs were taken according to standard procedures. Li salivary levels were performed by an adapted potentiometric method on the AVL9180 electrolyte analyzer. VPA salivary levels were taken with an immune-assay method with turbidimetric inhibition. A total of 50 patients (38 on Li, 12 on VPA) were enrolled. Blood-saliva bioequivalence for VPA was not found due to a high variability in salivary measures. Li measures resulted in a high correlation (r=0.767, p<0.001), showing no partial correlation with age (r=0.147, p=0.380). Li salivary test is a reliable method of measuring Li availability and is equivalent to serum levels. Potential advantages of Li salivary testing are its non-invasive nature and the possibility of doing the test during the usual appointment with the psychiatrist.

Effects of functional remediation on neurocognitively impaired bipolar patients: enhancement of verbal memory.

BACKGROUND: Functional remediation is a novel intervention with demonstrated efficacy at improving functional outcome in euthymic bipolar patients. However, in a previous trial no significant changes in neurocognitive measures were detected. The objective of the present analysis was to test the efficacy of this therapy in the enhancement of neuropsychological functions in a subgroup of neurocognitively impaired bipolar patients. METHOD: A total of 188 out of 239 DSM-IV euthymic bipolar patients performing below two standard deviations from the mean of normative data in any neurocognitive test were included in this subanalysis. Repeated-measures analyses of variance were conducted to assess the impact of the treatment arms [functional remediation, psychoeducation, or treatment as usual (TAU)] on participants' neurocognitive and functional outcomes in the subgroup of neurocognitively impaired patients. RESULTS: Patients receiving functional remediation (n = 56) showed an improvement on delayed free recall when compared with the TAU (n = 63) and psychoeducation (n = 69) groups as shown by the group × time interaction at 6-month follow-up [F 2,158 = 3.37, degrees of freedom (df) = 2, p = 0.037]. However, Tukey post-hoc analyses revealed that functional remediation was only superior when compared with TAU (p = 0.04), but not with psychoeducation (p = 0.10). Finally, the patients in the functional remediation group also benefited from the treatment in terms of functional outcome (F 2,158 = 4.26, df = 2, p = 0.016). CONCLUSIONS: Functional remediation is effective at improving verbal memory and psychosocial functioning in a sample of neurocognitively impaired bipolar patients at 6-month follow-up. Neurocognitive enhancement may be one of the active ingredients of this novel intervention, and, specifically, verbal memory appears to be the most sensitive function that improves with functional remediation.

The role of family interventions in bipolar disorder: A systematic review.

The reciprocal relationship between bipolar disorder (BD) and the family system highlights the importance of adjunctive family intervention. However, its implementation in clinical practice is not widespread. To update the knowledge in this field and identify areas of uncertainty this manuscript present a comprehensive overview of the bidirectional relationship between BD and family variables, and a systematic review of the evidence-based studies published up to March 2015 on the efficacy of adjunctive family intervention in BD. Findings show that not only specific family's attitudes/interactions affect the course of BD but that equally the illness itself has a strong impact on family functioning, caregivers' burden and health. Regarding family intervention, there are methodological differences between studies and variability in the sample characteristics and the intervention used. Most evidence-based studies support the efficacy of adjunctive family treatment in the illness outcomes, both in youth and adult population, as well as benefits for caregivers. The results emphasize the need to involve caregivers in the therapeutic management of BD through tailored interventions based on patients' characteristics and family needs.

The association between biological rhythms, depression, and functioning in bipolar disorder: a large multi-center study.

OBJECTIVE: We examined the relationship between biological rhythms and severity of depressive symptoms in subjects with bipolar disorder and the effects of biological rhythms alterations on functional impairment. METHOD: Bipolar patients (n = 260) and healthy controls (n = 191) were recruited from mood disorders programs in three sites (Spain, Brazil, and Canada). Parameters of biological rhythms were measured using the Biological Rhythms Assessment in Neuropsychiatry (BRIAN), an interviewer administered questionnaire that assesses disruptions in sleep, eating patterns, social rhythms, and general activity. RESULTS: Multivariate analyses of covariance showed significant intergroup differences after controlling for potential confounders (Pillai's F = 49.367; df = 2, P < 0.001). Depressed patients had the greatest biological rhythms disturbance, followed by patients with subsyndromal symptoms, euthymic patients, and healthy controls. Biological rhythms and HAMD scores were independent predictors of poor functioning (F = 12.841, df = 6, P < 0.001, R2  = 0.443). CONCLUSION: Our study shows a dose-dependent association between the severity of depressive symptoms and degree of biological rhythms disturbance. Biological rhythms disturbance was also an independent predictor of functional impairment. Although the directionality of this relationship remains unknown, our results suggest that stability of biological rhythms should be an important target of acute and long-term management of bipolar disorder and may aid in the improvement of functioning.

Bipolar disorder and antibodies against the N-methyl-d-aspartate receptor: A gate to the involvement of autoimmunity in the pathophysiology of bipolar illness.

The high prevalence of comorbidity between bipolar disorder (BD) and other medical conditions, including autoimmune diseases, supports the hypothesis of the nature of BD as a biological illness category. Hence, an immune dysregulation process may play an important role in the development of at least certain subtypes of BD. Increasing evidence also suggests that the N-methyl-d-aspartate receptor (NMDAR) may be relevant in the pathophysiology of BD. A possible key mechanism underlying the physiopathology of certain autoimmune diseases that may present with affective symptoms might be the production of anti-NMDAR auto-antibodies (auto-Abs). The best characterized autoimmune anti-NMDAR disease is the anti-NMDAR encephalitis. It has been found that 4% of these patients present isolated, mostly affective, psychiatric manifestations during their illness. An interesting suggestion emerged from this overview is that the same mechanisms that trigger affective symptoms in patients with increased anti-NMDAR auto-Abs levels could be involved in the physiopathology of at least a subgroup of BD. Future studies are needed to characterize the relationship between anti-NMDAR auto-Abs and BD.

Bipolar disorder with comorbid attention-deficit and hyperactivity disorder. Main clinical features and clues for an accurate diagnosis.

OBJECTIVE: To study the prevalence of attention-deficit and hyperactivity disorder (ADHD) in adult patients with bipolar disorder (BD) and identify differential clinical features for a better diagnosis. METHOD: A total of 163 euthymic bipolar out-patients were screened for ADHD with the ASRS.V1 and the WURS at a BD Unit. Patients with a positive screening were assessed with the CAADID, at an ADHD unit. Sociodemographic and clinical features of the groups with and without ADHD were compared. RESULTS: Lifetime prevalence of comorbid ADHD was 17.9% (10.5% for adult ADHD and 7.4% for childhood ADHD). The BD + ADHD group showed more suicidal behaviour although less severe. Comorbidity was also more common, especially regarding substance use disorders. Nevertheless, these patients did not show more affective episodes or hospitalizations and suffered more atypical but less melancholic depression. However, they required more treatment with psychotherapy and valproate. One-third of positive screenings at the ASRS were false; a severe course of BD was the hallmark of this subgroup. CONCLUSION: Adult patients with BD and ADHD show differential clinical features, but not a more severe course of BD. Comorbidity with substance abuse is a big issue, deserving special clinical attention. Better screening tools are necessary to avoid overdiagnosis of comorbid ADHD in BD.

Bipolar disorder in the elderly: a cohort study comparing older and younger patients.

OBJECTIVE: The purpose of this study was to analyze differences in clinical and socio-demographic characteristics between older and younger bipolar outpatients paying special attention to depressive symptoms in a large, naturalistic cohort. METHOD: Five hundred and ninety-three DSM-IV-TR bipolar outpatients were enrolled. Clinical characteristics were assessed according to DSM-IV-TR (SCID-I). Subjects were categorized into two groups according to current age (older OBD: age > 65 years; younger-YBD: age < 65 years). RESULTS: About 80% of patients were younger (N = 470), and a fifth were older (N = 123), with a mean age of 77.30 years in OBD. Older patients were more likely to be married, not qualified, bipolar II, with depressive polarity of first episode, higher age at illness onset, higher age at first hospitalization. They were more likely to present with depressive predominant polarity, with lifetime history of catatonic, psychotic and melancholic features, age at illness onset >40 years, as well as suffering from more medical comorbidities when compared to younger bipolars. CONCLUSION: The clinical presentation of bipolar disorder in late life would be defined more frequently by melancholic depressive features and a predominantly depressive polarity. These results suggest that treatment strategies for elderly bipolar patients should focus in the prevention of depressive episodes.

The risk of Bipolar Disorders in Multiple Sclerosis.

BACKGROUND: The aim was to determine the risk of Mood Disorders (MD), particularly Bipolar Disorders (BD), in Multiple Sclerosis (MS) using standardized psychiatric diagnostic tools. METHODS: Case-control study. CASES: 201 consecutive-patients with MS. CONTROLS: 804 sex- and age-matched subjects without MS, randomly selected from a database concurrently used for an epidemiological study on the MD prevalence in the community. Psychiatric diagnoses according to DSM-IV were determined by physicians using structured interview tools (ANTAS-SCID). RESULTS: Compared to controls, MS patients had a higher lifetime prevalence of DSM-IV Major Depressive Disorders (MDD; P<0.0001), BD I (P=0.05), BD II (P<0.0001) and Cyclothymia (P=0.0001). As people with MS had a higher risk of depressive and bipolar spectrum disorders, ratio MDD/bipolar spectrum disorders was lower among cases (P<0.005) indicating a higher association with Bipolar Spectrum Disorders and MS. LIMITATIONS: MS diagnosis was differently collected in cases and controls. Even if this might have produced false negatives in controls, it would have reinforced the null hypothesis of no increased risk for MD in MS; therefore, it does not invalidate the results of the study. CONCLUSIONS: This study was the first to show an association between BD and MS using standardized diagnostic tools and a case-control design. The results suggest a risk of under-diagnosis of BD (particularly type II) in MS and caution in prescribing ADs to people with depressive episodes in MS without prior excluding BD. The association between auto-immune degenerative diseases (like MS) and BD may be an interesting field for the study of the pathogenic hypothesis.

Treatment adherence in bipolar I and schizoaffective disorder, bipolar type.

BACKGROUND: Poor adherence rates in Bipolar Disorder type I (BDI) and Schizoaffective Disorder, bipolar type (SAD) may be high This study was aimed at comparing the clinical correlates of adherence to treatment and the course of illness in BDI and SAD patients. METHODS: 75 SAD and 150 BDI DSM-IV outpatients were included. Adherence was assessed on the basis of patients' and care-givers' reports and serum levels, when available. Socio-demographic, clinical and treatment variables were collected and compared between diagnostic subsamples and then between goodly and poorly adherent patients. Multiple logistic regressions were performed, controlling for diagnostic subsample differences, to identify correlates of adherence in BDI and SAD groups. RESULTS: Poor adherence was highly prevalent both in BDI (32%) and in SAD patients (44%), with no significant differences between diagnostic categories. Presence of psychotic symptoms (p=0.029), higher number of manic relapses (p<0.001), comorbidity with personality disorders (p=0.002), and lithium therapy (p=0.003) were associated with poor adherence to treatment. Diagnostic subgroup analyses showed different predictive models, with the BDI poorly adherent subsample being more likely to include comorbid personality and manic recurrences and the SAD poorly adherent subsample being less clinically predictable. LIMITATIONS: The cross-sectional nature of the study limits de capacity to ascertain the direction of the relationship between certain variables. CONCLUSIONS: Rates of poor adherence to oral treatments are similar in SAD and BDI. BDI patients with comorbid personality and substance use disorders are likely to be poorly adherent. Treatment adherence may be more difficult to predict in SAD patients.

Purpose and effectiveness of psychoeducation in patients with bipolar disorder in a bipolar clinic setting.

OBJECTIVE: This article reviews psychological therapies in the treatment of bipolar disorder, in particular psychoeducation, and how the inclusion of four fundamental principles - patient/therapist communication, flow of information, patient involvement and a trusting relationship - can improve patient outcomes. METHOD: The content of this article is based on the proceedings of a 1-day standalone symposium in November 2011 exploring how to establish a bipolar clinic within the context of existing services in the UK's National Health Service. RESULTS: Certain psychological interventions have emerged as beneficial add-on treatments to pharmacotherapy in bipolar disorder and are associated with greater stabilisation of symptoms, fewer relapses and longer time to relapse. Psychoeducation is a simple approach to support prevention of future episodes by delivering behavioural training to improve illness insight, early symptom identification and development of coping strategies. Empowering patients to actively participate in their treatment provides independence, counteracts the current disconnect of therapist and patient, and increases awareness and understanding of the challenges of living with and treating bipolar disorder. CONCLUSION: Psychoeducation enables patients to understand bipolar disorder, get actively involved in therapy planning, and be aware of methods for episode prevention, therefore effectively contributing to improved treatment outcomes and patient quality of life.

Mood instability and functional recovery in bipolar disorders.

OBJECTIVE: The aim of this study was to identify psychopathological factors associated with long-term functional outcome in euthymic bipolar disorder patients and to test new measures of mood instability and symptoms intensity. METHOD: Fifty-five patients with more than 12 months of follow-up were included. In addition to traditional clinical variables, the time spent ill was documented using a modified life-charting technique based on NIHM life-charting method. New measures, Mood Instability Factor, and Mood Intensity Factor were defined and assessed. Functioning Assessment Short Test (FAST) was used to assess disability. RESULTS: The follow-up period was 3.00 ± 1.51 years. Weeks with subsyndromal depressive symptoms (ß = 0.133, t = 2.556, P = 0.014), weeks with mild manic symptoms (ß = 1.441, t = 3.10, P = 0.003), and the Mood Instability Factor (ß = 0.105, t = 3.593, P = 0.001) contributed to approximately 46% of the FAST total score variance. CONCLUSION: New methodologies including subsyndromal symptoms and mood instability parameters might contribute to understand the worse long-term functional outcome that affects a considerable percentage of BD patients even after episode remission. Concerns about therapeutic approaches are discussed.

Faster onset of antimanic action with haloperidol compared to second-generation antipsychotics. A meta-analysis of randomized clinical trials in acute mania.

BACKGROUND: there is a lack of scientific data regarding speed of action of antimanic treatments, a relevant issue in clinical practice. OBJECTIVE: to assess differences in the speed of onset of antimanic efficacy between haloperidol (as most studied first-generation antipsychotic) and second-generation antipsychotics. EXPERIMENTAL PROCEDURES: meta-analysis of double-blind randomized clinical trials in acute mania, comparing treatment with haloperidol and with second-generation antipsychotics. Search was conducted in MEDLINE and CENTRAL databases (last search: September 2011). Differences in mania scale score reduction at week 1 were assessed. RESULTS: 8 randomized clinical trials fulfilled inclusion criteria and 1 of them was excluded due to low methodological quality. 2037 Manic patients had been treated with antipsychotics in the 7 trials. Haloperidol was found to be significantly more efficacious in the reduction of the mania scale score at week 1. The effect size was small, the Standardized Mean Difference (SMD) being 0.17, with a 95% Confidence Interval ranging from 0.01 to 0.32. Haloperidol was significantly more efficacious than olanzapine (SMD: 0.40 [0.21, 0.59]) and ziprasidone (0.39 [0.18, 0.61]). A non-significant trend towards superiority of haloperidol was found over aripiprazole (SMD: 0.13 [-0.02, 0.19]). There were no significant differences between haloperidol and quetiapine (0.17 [-0.11, 0.44]), and haloperidol and risperidone (SMD: -0.10 [0.30, 0.09]). CONCLUSIONS: haloperidol shows a faster onset of antimanic action than second-generation antipsychotics. This difference may be related to D2 affinity. Haloperidol may be considered a treatment option in severely ill manic patients who require urgent relief of symptoms.

Lower rate of depressive switch following antimanic treatment with second-generation antipsychotics versus haloperidol.

BACKGROUND: Treatment of acute mania with second-generation antipsychotics has been claimed to involve a lower risk of switch to depression than haloperidol. However, clinical guidelines clearly state that this is not a proven fact. METHODS: Meta-analysis of double-blind randomized controlled trials in acute mania, comparing rates of switch to depression with atypical antipsychotics and with haloperidol. Search was conducted in MEDLINE and CENTRAL databases (last search: September 2011). RESULTS: 8 randomized clinical trials fulfilled inclusion criteria. 2 of them were excluded because of low methodological quality or lack of data. 5 second-generation antipsychotics (aripiprazole, olanzapine, quetiapine, risperidone, and ziprasidone) were compared to haloperidol. In the mixed effects model the Risk Ratio for depressive switch was 0.71 (0.52, 0.96) favouring atypical antipsychotics. In the random effects model the difference did not reach statistical significance. In the heterogeneity analysis, exclusion of an outlying aripiprazole trial yielded a Risk Ratio of 0.58 (0.42, 0.82) with a non-significant heterogeneity test. Although no atypical antipsychotic was individually significantly superior to haloperidol, a trend could be seen favouring olanzapine (RR=0.56 [0.29, 1.08]), quetiapine (RR=0.36 [0.10, 1.33]), and ziprasidone (RR=0.51 [0.22, 1.18]). LIMITATIONS: All trials were industry supported, with some variability in dosage of haloperidol. Switch to depression was not the primary outcome of the trials. Heterogeneity could be explained as a lack of class-effect for atypicals. CONCLUSIONS: Treating acute mania with atypicals is associated to 42% less risk of switch to depression than with haloperidol. Nevertheless, caution should be taken when considering this a class effect, as only olanzapine, quetiapine, and ziprasidone may show a better profile.

Efficacy of psychoeducation on symptomatic and functional recovery in bipolar disorder.

OBJECTIVE: To evaluate the efficacy of psychoeducation in the symptomatic and functional recovery, and quality of life (QoL) in a sample of patients with bipolar disorder (BD). METHOD: The sample comprised 55 patients with BD I and II in remission (Young Mania Rating Scale ≤6 and Hamilton Depression Rating Scale ≤7). Out-patients were matched assigned to receive 16 sessions of psychoeducation [experimental group (EG)] or 16 sessions of placebo without psychoeducation [control group (CG)]. Groups were evaluated at study baseline, midpoint, endpoint, and at 6- and 12-month follow-ups. RESULTS: No significant differences between the groups were found for the variables evaluated (mood symptoms, functioning and QoL), except for overall clinical improvement, subjectively perceived by EG subjects. Both groups showed a trend toward improved clinical global impression and QoL (environmental). No reduction in mood symptoms or improvement in psychosocial functioning was observed. Psychosocial treatment compliance was positively correlated with global functioning, social adjustment, sociability, and global clinical impression. CONCLUSION: Sixteen session psychoeducation seems to be ineffective to prevent mood episodes or improve functioning in a sample of bipolar patients.

Rates and clinical correlates of treatment non-adherence in schizoaffective bipolar patients.

OBJECTIVE: To analyze demographical, clinical, and therapeutic variables that may be associated with pharmacological non-adherence in a sample of schizoaffective patients, bipolar type. METHOD: Adherence to treatment and its clinical correlates were assessed at the end of a 10-year follow-up in 76 patients meeting DSM-IV-TR diagnosis of schizoaffective disorder, bipolar type. Adherent and poorly adherent patients were compared regarding clinical and therapeutic variables. RESULTS: The rate of poorly adherent patients was 32/76 (41.2%) of the sample. Adherent patients were more likely to have presented an affective episode at illness onset and to have fewer purely - non-affective - psychotic episodes. Demographic or other clinical variables were not found to be associated to treatment adherence. Family history for psychiatric disorders or suicide did not correlate either, and neither did any specific pharmacological agent. CONCLUSION: Rates of non-adherence in schizoaffective disorder are high. Adherence seems to be associated to a more affective course of illness (affective first episode and fewer purely psychotic episodes). Patients with more prominent schizophrenia-like characteristics could be at higher risk for poor adherence and need to be closely followed and monitored. Even when properly treated, schizoaffective disorder is a disabling and severe disorder with high risk for recurrences.

What we know and what we don't know about the treatment of schizoaffective disorder.

Schizoaffective disorder (SAD) is a chronic, severe and disabling illness consisting on the concurrent presentation of symptoms of schizophrenia and affective disorders (depression and/or mania). Evidence for the treatment of SAD mostly derives from studies based on mixed samples (i.e. schizophrenic and schizoaffective patients) or on extrapolations from studies on schizophrenia or bipolar disorder. The objective of the present review is to systematically consider and summarize the best evidence-based approaches to the treatment of SAD and extensively point out the gap between treatment research and clinical practice of this disorder. The complex problem of controlling the pleomorphic presentation of SAD's syndromic construct is reflected in the lack of evidence on key topics, including: diagnostic consistency, pharmacological approaches (mood stabilizers, antidepressants, both in acute and maintenance treatment as well as their possible combination), and the adjunctive role of psychosocial and biophysical interventions. Finally, treatment strategies for SAD, both unipolar and bipolar type, are proposed.
