Quality of life of family primary caregivers of individuals with bipolar disorder and schizophrenia in south of Brazil.

BACKGROUND: The process of deinstitutionalization of individuals with mental disorders (MD) brought greater family responsibility in terms of patient care. AIMS: Evaluate the Quality of Life (QoL) and its associated factors of primary caregivers of bipolar and schizophrenic subjects. METHODS: A cross-sectional survey was conducted from 2012 to 2015 with 125 caregivers at an outpatient service of a teaching hospital in the South of Brazil. QoL instruments (WHOQOL-Bref, SF-36), questionnaires regarding socio-demographic, clinical data and depressive symptoms (BDI) were applied. RESULTS: Caregivers of schizophrenic individuals presented lower QoL scores than caregivers of bipolar individuals, with moderate effect in physical, and social domains of WHOQOL-Bref, and in physical functioning, role-physical, and role-emotional domains of SF-36. QoL scores of caregivers were lower when compared with the normative data of the Brazilian population. The factors associated with lower QoL scores were: patient diagnosis of schizophrenia, female gender, presence of clinical disease and presence of depressive symptoms in the caregiver. CONCLUSIONS: Caregivers of patients with schizophrenia or bipolar disorder present a significant impairment in their QoL when compared with the general population, highlighting the relevance of developing support programs in the mental health services that include these caregivers.

Hypothesis: Compulsive hoarding as an atavism.

In this hypothesis paper, we propose that hoarding disorder may be an ancestral mammalian behavior, possibly hard-wired but dormant in present-day humans, that can be activated by traumatic experiences. To support this claim, we describe hoarding in ancestral mammals and provide examples of recurrence of traits, or atavisms, in humans and other mammals, highlighting its implications for neuropsychiatric diseases. We highlight the potential of using shrews as animal models for hoarding behavior and, considering the current knowledge on the molecular underpinnings of the disorder, we also point to limitations of the proposed connection.

Bipolar Disorder Mixed Episodes: A Pragmatic Trial of a Public Health Treatment Effectiveness.

OBJECTIVES: To evaluate the effectiveness of an algorithm for the treatment of mixed episodes in bipolar disorder (BD) using the medications available under the Unified Health System (Sistema Único de Saúde) in Brazil. METHODS: The study included 107 individuals with BD in a current mixed episode, assessed biweekly for the outcomes of response and remission. The subjects were randomly assigned to start treatment with lithium, valproic acid, or carbamazepine, following a clinical protocol at a public outpatient clinic. Eligibility screening instruments, semistructured interview, and clinical psychiatric evaluation were used for diagnosis. To measure response and remission, the Hamilton Rating Scale for Depression and the Young Mania Rating Scale were used. A parameter of 50% or less in the symptom scales was used to define responses, as assessed by Kaplan-Meier time-event analysis. RESULTS: For the main outcome, response to treatment, all interventions proposed were proven to be effective, with no difference in response time for any of them. There was a lack of placebo control and blinding for intervention or outcomes. Individuals with mixed episodes in BD often face contradictory symptoms, and these inherent difficulties are the main obstacles to stabilize such a condition. CONCLUSIONS: The findings presented in this study show that the treatments available under the Unified Health System are able to reduce the overall burden of disease in terms of symptom reduction.

Amiodarone for arrhythmia in patients with Chagas disease: A systematic review and individual patient data meta-analysis.

BACKGROUND: Chagas disease is a neglected chronic condition caused by Trypanosoma cruzi, with high prevalence and burden in Latin America. Ventricular arrhythmias are common in patients with Chagas cardiomyopathy, and amiodarone has been widely used for this purpose. The aim of our study was to assess the effect of amiodarone in patients with Chagas cardiomyopathy. METHODOLOGY: We searched MEDLINE, Embase and LILACS up to January 2018. Data from randomized and observational studies evaluating amiodarone use in Chagas cardiomyopathy were included. Two reviewers selected the studies, extracted data and assessed risk of bias. Overall quality of evidence was accessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE). PRINCIPAL FINDINGS: We included 9 studies (3 before-after studies, 5 case series and 1 randomized controlled trial). Two studies with a total of 38 patients had the full dataset, allowing individual patient data (IPD) analysis. In 24-hour Holter, amiodarone reduced the number of ventricular tachycardia episodes in 99.9% (95%CI 99.8%-100%), ventricular premature beats in 93.1% (95%CI 82%-97.4%) and the incidence of ventricular couplets in 79% (RR 0.21, 95%CI 0.11-0.39). Studies not included in the IPD analysis showed a reduction of ventricular premature beats (5 studies), ventricular tachycardia (6 studies) and ventricular couplets (1 study). We pooled the incidence of adverse side effects with random effects meta-analysis; amiodarone was associated with corneal microdeposits (61.1%, 95%CI 19.0-91.3, 5 studies), gastrointestinal events (16.1%, 95%CI 6.61-34.2, 3 studies), sinus bradycardia (12.7%, 95%CI 3.71-35.5, 6 studies), dermatological events (10.6%, 95%CI 4.77-21.9, 3 studies) and drug discontinuation (7.68%, 95%CI 4.17-13.7, 5 studies). Quality of evidence ranged from moderate to very low. CONCLUSIONS: Amiodarone is effective in reducing ventricular arrhythmias, but there is no evidence for hard endpoints (sudden death, hospitalization). Although our findings support the use of amiodarone, it is important to balance the potential benefits and harms at the individual level for decision-making.

Electronic Version of the EQ-5D Quality-of-Life Questionnaire: Adaptation to a Brazilian Population Sample.

OBJECTIVES: To assess the measurement equivalence of the original paper version of an adapted tablet version of the EuroQol five-dimensional questionnaire (EQ-5D). METHODS: A randomly selected sample of 509 individuals aged 18 to 64 years from the general population responded to the EQ-5D at two time points separated by a minimum interval of 24 hours and were allocated to one of the following groups: test-retest group (tablet-tablet) or crossover group (paper-tablet and tablet-paper). Agreement between methods was determined using the intraclass correlation coefficient (ICC) and the κ coefficient. RESULTS: In the crossover group, the following ICC values were obtained: 0.76 (confidence interval [CI] 0.58-0.89) for EQ-5D scores and 0.77 (CI 0.68-0.84) for visual analogue scale in subjects responding first to the tablet version; 0.83 (CI 0.75-0.89) for EQ-5D scores and 0.75 (CI 0.67-0.85) for visual analogue scale in subjects responding first to the paper version. In the test-retest group, the ICC was 0.85 (CI 0.73-0.91) for EQ-5D scores and 0.79 (CI 0.66-0.87) for visual analogue scale. The κ values were higher than 0.69 in this group. The internal consistencies of the paper and tablet methods were similar. CONCLUSIONS: The paper and tablet versions of the EQ-5D are equivalent. Test-retest and crossover agreement was high and the acceptability of the methods was similar among individuals.

[Cue exposure treatment and coping skills training as adjuvant therapies in the management of craving in a crack cocaine addict]. / Tratamento de exposição a estímulos e treinamento de habilidades como coadjuvantes no manejo do craving em um dependente de crack.

OBJECTIVE: An increased prevalence of crack cocaine users has been observed in clinical samples over the past years, underscoring the need for conducting research and developing treatment strategies aimed at this population. The objective of this study was to describe the case of a crack cocaine addict (inpatient) submitted to cue exposure treatment (CET) and coping skills training (CS) as adjuvant approaches to the conventional addiction treatment. CASE DESCRIPTION: A male patient, 29 years old, single, with complete high school, was dependent on crack cocaine and marijuana and also had a diagnosis of harmful alcohol use. The patient had been hospitalized for 2 weeks and had undertaken a protocol comprising four motivational interview and relapse prevention sessions. Six sessions of CET and CS were carried out over 2 weeks, including both in vivo and imaginal exposure to stimuli evoking craving for crack cocaine, such as a crack pipe, a lighter, and simulated crack cocaine rocks (in vivo exposure), or remembering places and friends associated with drug use (imaginal exposure). The patient was also trained to use strategies for the management of craving. Three months after hospital discharge, toxicological screening was performed to assess abstinence. CET and CS were considered by the patient to be important techniques for the maintenance of abstinence and of a low level of craving 3 months after discharge. COMMENTS: These findings suggest that the two techniques may be useful as adjuvant therapies in the treatment of crack cocaine dependents. CET and CS should be assessed in clinical trials in order to demonstrate their real benefits.

Tratamento de exposição a estímulos e treinamento de habilidades como coadjuvantes no manejo do craving em um dependente de crack / Cue exposure treatment and coping skills training as adjuvant therapies in the management of craving in a crack cocaine addict

OBJETIVO: Tem-se observado um aumento da prevalência de dependentes de crack em amostras clínicas, o que torna necessária a realização de pesquisas quanto a estratégias de tratamento direcionadas a essa clientela. O objetivo deste estudo foi descrever o caso de um dependente de crack internado no qual foram utilizados o tratamento de exposição a estímulos (TEE) e o treinamento de habilidades (TH) como coadjuvantes ao tratamento tradicional. DESCRIÇÃO DO CASO: O paciente é do sexo masculino, 29 anos de idade, solteiro, ensino médio completo. Era dependente de crack e de maconha e fazia uso nocivo de álcool. O paciente já estava internado havia 2 semanas e tinha passado por um protocolo de quatro sessões com entrevista motivacional e prevenção à recaída. Foram feitas seis sessões, ao longo de 2 semanas, de TEE e TH, nas quais o paciente foi exposto in vivo e pela imaginação a estímulos evocadores de fissura, como cachimbo de crack, isqueiro, pedras simuladas, lembranças de locais e amigos associados ao uso da droga. Ele também foi treinado para utilizar estratégias de manejo da fissura. Após 3 meses da alta hospitalar, foi realizado screening toxicológico para avaliar a manutenção de abstinência. O paciente avaliou o uso das técnicas como importante para a manutenção da abstinência após 3 meses da alta e para sua baixa média de fissura pelo crack. COMENTÁRIOS: Talvez o TEE e o TH para manejo da fissura possam ser úteis como coadjuvantes no tratamento de dependentes de crack. Tal uso deve ser avaliado em ensaios clínicos para demonstrar seu real benefício (AU)

Evidence that folic acid deficiency is a major determinant of hyperhomocysteinemia in Parkinson's disease.

In the present work we measured blood levels of total homocysteine ((t)Hcy), vitamin B(12) and folic acid in patients with Parkinson s disease (PD) and in age-matched controls and searched for possible associations between these levels with smoking, alcohol consumption, L-DOPA treatment and disease duration in PD patients. We initially observed that plasma (t)Hcy levels were increased by around 30 % in patients affected by PD compared to controls. Linear correlation, multiple regression and comparative analyses revealed that the major determinant of the increased plasma concentrations of (t)Hcy in PD patients was folic acid deficiency, whereas in controls (t)Hcy levels were mainly determined by plasma vitamin B(12) concentrations. We also observed that alcohol consumption, gender and L-DOPA treatment did not significantly alter plasma (t)Hcy, folic acid and vitamin B(12) levels in parkinsonians. Furthermore, disease duration was positively associated with (t)Hcy levels and smoking was linked with a deficit of folic acid in PD patients. Considering the potential synergistic deleterious effects of Hcy increase and folate deficiency on the central nervous system, we postulate that folic acid should be supplemented to patients affected by PD in order to normalize blood Hcy and folate levels, therefore potentially avoiding these risk factors for neurologic deterioration in this disorder.
