Distinct effects of cocaine and cocaine + cannabis on neurocognitive functioning and abstinence: A six-month follow-up study.

BACKGROUND AND AIMS: Cannabis use is frequent among individuals with cocaine use disorder. Despite recent non-controlled studies advocating a therapeutic role of smoked cannabis, there is a paucity of evidence-based data on potential therapeutic and cognitive side-effects of this association. METHODS: We examined 63 cocaine-addicted subjects who used cannabis more than 50 times in lifetime (COC + CAN), 24 cocaine-addicted patients who use cannabis less than 50 times (COC), and 36 controls (CON). Participants were evaluated with an extensive battery of neurocognitive tests after two weeks of supervised detoxification in an inpatient treatment program. Patients were followed up in one, three, and six months after discharge. RESULTS: Both groups of patients performed worse than CON on working memory, processing speed, inhibitory control, mental flexibility, and decision making. COC + CAN performed worse than COC on speed processing, inhibitory control and sustained attention, while COC performed worse than COC + CAN on mental flexibility. Concomitant cannabis use did not decrease relapses to cocaine use after one, three and six months. Among COC + CAN, earlier cocaine and cannabis use, and impaired executive functioning were predictive of relapse on cocaine after six months. CONCLUSION: Our results did not support the recommendation of smoked cannabis as a safe therapeutic approach for cocaine-addicted patients due to significant negative cognitive side-effects and absence of efficacy. Further studies investigating frontal brain morphology, neuromaturation, and prescription of the non-psychoactive constituent of cannabis sativa cannabidiol among cocaine-addicted patients who use cannabis are warranted.

Efficacy of electroconvulsive therapy augmentation for partial response to clozapine: a pilot randomized ECT – sham controlled trial

Abstract Background Thirty percent of schizophrenia patients are treatment-resistant. Objective This is a single-blinded sham-controlled trial to assess the efficacy of electroconvulsive therapy (ECT) as augmentation strategy in patients with clozapine-resistant schizophrenia. Methods Twenty three subjects were randomly assigned to 12 sessions of ECT (N = 13) or placebo (Sham ECT) (N = 10). The primary outcome was improvement on psychotic symptoms as measured by the mean reduction of the PANSS positive subscale. The assessments were performed by blind raters. Results At baseline both groups were similar, except for negative and total symptoms of the PANSS, which were higher in the Sham group. At the endpoint both groups had a significant decrease from basal score. In the ECT group the PANSS total score decreased 8.78%, from 81.23 to 74.75 (p = 0.042), while the positive subscale had a mean reduction of 19% (19.31 to 16.17, p = 0.006). In the Sham group, the mean reduction of PANSS total score was 15.27% (96.80 to 87.43; p = 0.036), and the PANSS positive subscale decreased 27.81% (22.90 to 19.14, p = 0.008). The CGI score in ECT group decreased 23.0% (5.23 to 4.17; p = 0.001) and decreased 24.31% in the Sham ECT group (5.80 to 4.86; p = 0.004). Discussion In this pilot study, we found no difference between the groups.

Risk Factors for Diagnostic Delay in Psychogenic Nonepileptic Seizures Among Children and Adolescents.

BACKGROUND: This study aims to analyze a series of pediatric patients with psychogenic nonepileptic seizures (PNES) to establish the diagnostic gap and possible risk factors for the delayed diagnosis in this age group. METHODS: We evaluated all children with PNES documented by video electroencephalography. None had a previous diagnosis of PNES. In total, we included 53 children (interquartile range: seven to 17 years; mean age 12.81 years [S.D. 3.15]; 60.4% girls) who underwent a protocol consisting of neurological and psychiatric interviews. RESULTS: The average time between seizure onset and referral was 17.76 months (interquartile range: 0.5 to 48 months; S.D. ± 12.62). Earlier age of onset correlated with a later diagnosis (P < 0.001). The late referral group also presented with a history of psychological abuse (P = 0.018). CONCLUSION: Youth with PNES represent a diagnostic challenge. Identification of children at risk might lead to earlier diagnosis of PNES.

Co-occurrence of communication disorder and psychiatric disorders in maltreated children and adolescents: relationship with global functioning

Objective: To study the co-occurrence of psychiatric disorders (PD) and communication disorders (CD) and their relationship with global functioning in maltreated children and adolescents. Methods: The sample comprised 143 maltreated children and adolescents (55.8% male). All underwent clinical communication and psychiatric evaluations, as well as global functioning assessment using the Children’s Global Assessment Scale (C-GAS). Results: Four groups emerged from evaluation: Group 1 (n=7, 4.9%) did not exhibit any disorders; Group 2 (n=26, 18.2%) exhibited PD; Group 3 (n=34, 23.8%) exhibited CD; and Group 4 (n=76, 53.1%) exhibited both PD and CD on evaluation. Significant differences in global functioning scores were found between G1 and G2, G1 and G4, G2 and G4, and G3 and G4, with the highest C-GAS scores found in G1 and the lowest in G4. Conclusion: Rates of PD and CD are high in this maltreated population. The presence of PD has a major impact on C-GAS score, and the simultaneous presence of CD increases the already impaired function of PD. Demonstration of the additive effects of PD and CD on youth functioning suggests that professionals should be alert to the presence of both disorders to better act preventively and therapeutically in a high-risk population.

Hypertension prevalence among indigenous populations in Brazil: a systematic review with meta-analysis / Prevalencia de hipertensión arterial en indígenas de Brasil: una revisión sistemática con meta-análisis / Prevalência de hipertensão arterial em indígenas do Brasil: uma revisão sistemática com meta-análise

Abstract OBJECTIVE Evaluating the evidence of hypertension prevalence among indigenous populations in Brazil through a systematic review and meta-analysis. METHODS A search was performed by two reviewers, with no restriction of date or language in the databases of PubMed, LILACS, SciELO, Virtual Health Library and Capes Journal Portal. Also, a meta-regression model was designed in which the last collection year of each study was used as a moderating variable. RESULTS 23 articles were included in the review. No hypertension was found in indigenous populations in 10 studies, and its prevalence was increasing and varied, reaching levels of up to 29.7%. Combined hypertension prevalence in Indigenous from the period of 1970 to 2014 was 6.2% (95% CI, 3.1% - 10.3%). In the regression, the value of the odds ratio was 1.12 (95% CI, 1.07 - 1.18; p <0.0001), indicating a 12% increase every year in the probability of an indigenous person presenting hypertension. CONCLUSION There has been a constant increase in prevalence despite the absence of hypertension in about half of the studies, probably due to changes in cultural, economic and lifestyle habits, resulting from indigenous interaction with non-indigenous society.

Self-care in heart failure patients / Autocuidado de pacientes com insuficiência cardíaca / Autocuidado de los pacientes con insuficiencia cardíaca

AbstractObjective: to describe self-care behavior and its associated factors in a sample of heart failure Brazilian patients.Method: descriptive cross-sectional study with non-probabilistic sample of 116 ambulatory patients undergoing heart failure treatment. Self-care was evaluated using the Self-Care of Heart Failure Index, (scores ≥70 points=appropriate self-care). Association tests were applied, considering a descriptive level of 0.05.Results: the mean age of participants was 57.7 (SD =11.3) years; 54.3% were male; the mean schooling was 5.5 (SD = 4.0) years; and 74.1% had functional class II-III. The mean scores on the subscales of the Self-Care of Heart Failure Index indicated inappropriate self-care (self-care maintenance: 53.2 (SD =14.3), selfcare management: 50.0 (SD = 20.3) and self-care confidence: 52.6 (SD=22.7)) and it was found low frequencies of participants with appropriate self-care (self-care maintenance, 6.9%), self-care management (14.7%) and self-care confidence (19%). Higher scores of the Self-Care of Heart Failure Index were associated with: reduced left ventricular ejection fraction (p=0.001), longer time of experience with the disease (p=0.05) and joint monitoring by physician and nurse (p=0.007).Conclusion: investments are needed to improve the self-care behavior and the nursing can play a relevant role in this improvement.

Association study in Alzheimer’s disease of single nucleotide polymorphisms implicated with coffee consumption

There is evidence from animal and in vitro models of the protective effects of caffeine in Alzheimer’s disease. The suggested mechanisms through which caffeine may protect neurons against Alzheimer’s disease pathology include the facilitation of beta-amyloid clearance, upregulation of cholinergic transmission, and increased neuronal plasticity and survival. Epidemiological studies support that Alzheimer’s disease patients consume smaller amounts of coffee beverages throughout their lives as compared to age-matched cognitively healthy individuals. Objective: The aim of the present study was to determine whether the negative association between Alzheimer’s disease and coffee consumption may be influenced by a common genetic predisposition, given the fact that the pattern of coffee consumption is determined by both environmental and genetic factors. Method: We conducted an in silico search addressing the association between genetic polymorphisms related to coffee consumption and the diagnosis of Alzheimer’s disease. We further investigated the interactions between genes located in regions bearing these polymorphisms. Results: Our analysis revealed no evidence for a genetic association (nor interaction between related proteins) involving coffee consumption and Alzheimer’s disease. Discussion: The negative association between Alzheimer’s disease and coffee consumption suggested by epidemiological studies is most likely due to environmental factors that are not necessarily regulated by genetic background...

Auditory-perceptual analysis of voice in abused children and adolescents / Análise perceptivo-auditiva da voz de crianças e adolescentes vítimas de maus tratos

Introduction: Abused children and adolescents are exposed to factors that can trigger vocal changes. Objective: This study aimed to analyze the prevalence of vocal changes in abused children and adolescents, through auditory-perceptual analysis of voice and the study of the association between vocal changes, communication disorders, psychiatric disorders, and global functioning. Methods: This was an observational and transversal study of 136 children and adolescents (mean age 10.2 years, 78 male) who were assessed by a multidisciplinary team specializing in abused populations. Speech evaluation was performed (involving the aspects of oral and written communication, as well as auditory-perceptual analysis of voice, through the GRBASI scale). Psychiatric diagnosis was performed in accordance with the DSM-IV diagnostic criteria and by applying the K-SADS; global functioning was evaluated by means of the C-GAS scale. Results: The prevalence of vocal change was 67.6%; of the patients with vocal changes, 92.3% had other communication disorders. Voice changes were associated with a loss of seven points in global functioning, and there was no association between vocal changes and psychiatric diagnosis. Conclusion: The prevalence of vocal change was greater than that observed in the general population, with significant associations with communication disorders and global functioning. The results demonstrate that the situations these children experience can intensify the triggering of abusive vocal behaviors and consequently, of vocal changes. .

Introdução: Crianças e adolescentes vítimas de maus tratos estão expostas a fatores que podem desencadear alterações vocais. Objetivo: Analisar a prevalência de alteração vocal nesta população realizando análise perceptivo-auditiva da voz e estudar a associação entre alteração vocal, transtornos da comunicação, transtorno psiquiátrico e funcionamento global. Método: Estudo observacional e transversal. Participaram 136 sujeitos, com idade média de 10,2 anos, atendidos por equipe multidisciplinar especializada no tratamento ambulatorial de vítimas de maus tratos. Foi realizada avaliação fonoaudiologia (aspectos da comunicação orale escrita e análise perceptivo-auditiva da voz a qual foi feita por meio da escala GRBASI). O diagnóstico psiquiátrico foi dado de acordo com os critérios diagnósticos da CID-10 e aplicação do K-SADS; o funcionamento global foi avaliado por meio da escala C-GAS. Resultados: A prevalência de alteração vocal foi de 67,6%, dos pacientes com alteração vocal, 92,3% apresentaram outros transtornos da comunicação. A alteração vocal está associada a um prejuízo de sete pontos no funcionamento global e não apresentou associação com transtorno psiquiátrico. Conclusão: A prevalência de alterações vocais encontrada foi maior do que a observada na população geral, com associações significantes com transtornos da comunicação e funcionamento global. As situações que estas crianças vivem podem intensificar o desencadeamento de comportamentos vocais abusivos e consequentemente de alterações vocais. .

Religiousness and health-related quality of life of older adults / Religiosidade e qualidade de vida relacionada à saúde do idoso

OBJECTIVE To examine whether religiousness mediates the relationship between sociodemographic factors, multimorbidity and health-related quality of life of older adults. METHODS This population-based cross-sectional study is part of the Survey on Health, Well-Being, and Aging (SABE). The sample was composed by 911 older adults from Sao Paulo, SP, Southeastern Brazil. Structural equation modeling was performed to assess the mediator effect of religiousness on the relationship between selected variables and health-related quality of life of older adults, with models for men and women. The independent variables were: age, education, family functioning and multimorbidity. The outcome variable was health-related quality of life of older adults, measured by SF-12 (physical and mental components). The mediator variables were organizational, non-organizational and intrinsic religiousness. Cronbach's alpha values were: physical component = 0.85; mental component = 0.80; intrinsic religiousness = 0.89 and family APGAR (Adaptability, Partnership, Growth, Affection, and Resolve) = 0.91. RESULTS Higher levels of organizational and intrinsic religiousness were associated with better physical and mental components. Higher education, better family functioning and fewer diseases contributed directly to improved performance in physical and mental components, regardless of religiousness. For women, organizational religiousness mediated the relationship between age and physical (β = 2.401, p < 0.01) and mental (β = 1.663, p < 0.01) components. For men, intrinsic religiousness mediated the relationship between education and mental component (β = 7.158, p < 0.01). CONCLUSIONS Organizational and intrinsic religiousness had a beneficial effect on the relationship between age, education and health-related quality of life of these older adults.

OBJETIVO : Analisar se a religiosidade exerce efeito mediador na relação entre fatores sociodemográficos, multimorbidade e qualidade de vida relacionada à saúde em idosos. MÉTODOS : Este estudo transversal, de base populacional, é parte do estudo Saúde, Bem-Estar e Envelhecimento (SABE). A amostra foi composta por 911 idosos da cidade de São Paulo, residentes na comunidade. A modelagem de equações estruturais foi realizada para verificar o efeito mediador da religiosidade na relação entre variáveis selecionadas e a qualidade de vida relacionada à saúde dos idosos, com modelos para homens e mulheres. As variáveis independentes foram: idade, escolaridade, funcionalidade familiar e multimorbidade. A variável de desfecho foi a qualidade de vida relacionada à saúde, medida pelo SF-12 (componentes físico e mental). As variáveis mediadoras foram a religiosidade organizacional, a não organizacional e a intrínseca. Os coeficientes alfa de Cronbach foram: componente físico = 0,85; componente mental = 0,80; religiosidade intrínseca = 0,89 e Apgar familiar = 0,91. RESULTADOS : Maiores níveis de religiosidade organizacional e intrínseca estiveram associados a melhor componente físico e mental para os idosos. Maior escolaridade, melhor funcionalidade familiar e menor número de doenças contribuíram diretamente para melhor desempenho nos componentes físico e mental, independente da religiosidade. Para as mulheres, a religiosidade organizacional mediou a relação entre a idade e os componentes físico (β = 2,401; p < 0,01) e mental (β = 1,663; p < 0,01). Para os homens, a religiosidade intrínseca mediou a relação entre a escolaridade e o componente mental (β = 7,158; p < 0,01). CONCLUSÕES : A religiosidade organizacional e intrínseca exercem efeito benéfico sobre a relação entre idade, escolaridade e a qualidade de vida relacionada à saúde desses idosos.

Association of child maltreatment and psychiatric diagnosis in Brazilian children and adolescents.

OBJECTIVES: The objective of this study was to evaluate the association between different types of child maltreatment and the presence of psychiatric disorders in highly vulnerable children and adolescents served by a multidisciplinary program. METHODS: In total, 351 patients with a mean age of 12.47, of whom 68.7% were male and 82.1% lived in shelters, underwent psychiatric evaluations based on the Kiddie-Sads-Present and Lifetime Version. Two different methods were used to evaluate maltreatment: medical records were reviewed to identify previous diagnoses related to socioeconomic and psychosocial circumstances, and the Childhood Trauma Questionnaire was used to obtain a structured history of trauma. Bivariate associations were evaluated between psychiatric disorders and evidence of each type and the frequency of abuse. RESULTS: The most frequent psychiatric diagnoses were substance use disorders, affective disorders and specific disorders of early childhood, whereas 13.67% of the sample had no psychiatric diagnosis. All patients suffered neglect, and 58.4% experienced physical or sexual abuse. The presence of a history of multiple traumas was only associated with a diagnosis of substance use disorder. Mental retardation showed a strong positive association with reported physical abuse and emotional neglect. However, a negative correlation was found when we analyzed the presence of a history of multiple traumas and mental retardation. CONCLUSION: All children living in adverse conditions deserve careful assistance, but we found that physical abuse and emotional neglect were most strongly associated with mental retardation and multiple traumas with substance abuse.

Polydrug use among college students in Brazil: a nationwide survey.

OBJECTIVE: To estimate the frequency of polydrug use (alcohol and illicit drugs) among college students and its associations with gender and age group. METHODS: A nationwide sample of 12,544 college students was asked to complete a questionnaire on their use of drugs according to three time parameters (lifetime, past 12 months, and last 30 days). The co-use of drugs was investigated as concurrent polydrug use (CPU) and simultaneous polydrug use (SPU), a subcategory of CPU that involves the use of drugs at the same time or in close temporal proximity. RESULTS: Almost 26% of college students reported having engaged in CPU in the past 12 months. Among these students, 37% had engaged in SPU. In the past 30 days, 17% college students had engaged in CPU. Among these, 35% had engaged in SPU. Marijuana was the illicit drug mostly frequently used with alcohol (either as CPU or SPU), especially among males. Among females, the most commonly reported combination was alcohol and prescribed medications. CONCLUSIONS: A high proportion of Brazilian college students may be engaging in polydrug use. College administrators should keep themselves informed to be able to identify such use and to develop educational interventions to prevent such behavior.

The co-use of drugs was investigated as concurrent polydrug use (CPU) and simultaneous polydrug use (SPU), a subcategory of CPU that involves the use of drugs at the same time or in close temporal proximity. Results: Almost 26% of college students reported having engaged in CPU in the past 12 months. Among these students, 37% had engaged in SPU. In the past 30 days, 17% college students had engaged in CPU. Among these, 35% had engaged in SPU. Marijuana was the illicit drug mostly frequently used with alcohol (either as CPU or SPU), especially among males. Among females, the most commonly reported combination was alcohol and prescribed medications. Conclusions: A high proportion of Brazilian college students may be engaging in polydrug use. College administrators should keep themselves informed to be able to identify such use and to develop educational interventions to prevent such behavior. .

Single-nucleotide polymorphisms of GSK3B, GAB2 and SORL1 in late-onset Alzheimer's disease: interactions with the APOE genotype.

In this study, we investigated the associations between single-nucleotide polymorphisms in GAB2 (rs2373115), GSK3B (rs6438552) and SORL1 (rs641120) and Alzheimer's disease (AD), both alone and in combination with the APOE*4 allele.
