Halfway Houses for Alcohol Dependents: From Theoretical Bases to Implications for the Organization of Facilities

The purpose of this paper is to supply a narrative review of the concepts, history, functions, methods, development and theoretical bases for the use of halfway houses for patients with mental disorders, and their correlations, for the net construction of chemical dependence model. This theme, in spite of its relevance, is still infrequently explored in the national literature. The authors report international and national uses of this model and discuss its applicability for the continuity of services for alcohol dependents. The results suggest that this area is in need of more attention and interest for future research

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men

Prevalence of substance use among trauma patients treated in a Brazilian emergency room

OBJECTIVE: Although there is a considerable amount of data in the literature regarding the association between alcohol consumption and injuries treated in emergency rooms, little is known about the relationship between such injury and the use of other substances. The objective of this study was to estimate the prevalence of substance use in patients admitted to the emergency room for non-fatal injuries. METHOD: A prospective cross-sectional study assessing all patients admitted to the emergency room within 6 hours after a non-fatal injury was conducted over a three-month period. The following were used as measures of alcohol and drug use: a standardized World Health Organization questionnaire; a self-administered questionnaire related to drug consumption within the 24 hours preceding contact; the Drug Abuse Screening Test; urine screens for cannabis, cocaine and benzodiazepines; and determination of blood alcohol concentration. Descriptive analyses were performed and the confidence interval used was 95%. RESULTS: A total of 353 patients were included. Cannabis and cocaine screens were conducted for 242 patients and benzodiazepine screens were conducted for 166. Blood alcohol concentrations reached the level of positivity in 11% (n = 39), and 10% (n = 33) presented some degree of intoxication. Among the 242 patients screened, 13.6% (n = 33) tested positive for cannabis, and 3.3% (n = 8) tested positive for cocaine, whereas 4.2% (n = 7) of the 166 patients screened tested positive for benzodiazepines. CONCLUSIONS: Substance use was highly prevalent among these individuals. In this sample, the frequency for the use of cannabis (an illicit drug) was comparable to that of alcohol. More studies are needed in order to characterize such use among Brazilians and to develop proper approaches to such cases, with the aim of reducing substance use and its consequences

Craving decrease with topiramate in outpatient treatment for cocaine dependence: an open label trial Diminuição da fissura com topiramato no tratamento ambulatorial para dependência de cocaína: um ensaio clínico aberto

OBJECTIVE: To evaluate anticraving action and tolerability of topiramate in cocaine user treatment. METHOD: Male users of inhaled cocaine which met criteria for cocaine dependence (Diagnostic and Statistical Manual of Mental Disorders, fourth edition) were selected for outpatient 12-week, open label trial with topiramate; individual dosage ranged between 25-300 mg/day. Main clinical variables were abstinence rate, craving intensity, frequency and duration, adherence, dropouts, side effects and impulsivity measure through Barratt Impulsivity Scale. Patients received assertive strategic counseling for abstinence assistance and medication monitoring evaluation every two weeks. Comparative analysis was made with intention to treat, missing values were replaced (last observation carried forward), and significance level was 5%. RESULTS: Adherence to treatment was 57% (at least three evaluations), 32% dropped out (one evaluation). There were no severe side effects. Negative test average was 25.4% (31.2). Significant reduction in craving intensity and duration was observed in 25% of the sample. No statistical significant reduction in craving frequency was observed in 7.1%. Increase in frequency was observed in 10.7% and 82.1% did not present any variation. No significant statistical variations in Barratt Impulsivity Scale or in the total score were found in the final evaluation when compared to baseline. CONCLUSION: More randomized placebo-controlled trials with topiramate for cocaine dependants should be performed to evaluate preliminary evidence.<br>OBJETIVO: Avaliar a ação anticraving e tolerabilidade do topiramato em usuários de cocaína. MÉTODO: Homens usuários de cocaína inalada que preenchiam critérios para dependência de cocaína (Manual Diagnóstico e Estatístico de Desordens Mentais, quarta edição) foram selecionados para 12 semanas de tratamento ambulatorial, em ensaio clínico aberto com topiramato; dosagens escalonadas entre 25-300 mg/dia. As principais variáveis clínicas foram taxa de abstinência, intensidade, freqüência e duração do craving, aderência, perdas, efeitos colaterais e impulsividade medida por meio da Escala de Impulsividade Barratt. Os pacientes receberam estratégias assertivas de aconselhamento para manutenção da abstinência e monitoramento da medicação avaliada a cada duas semanas. Análises comparativas foram feitas com intenção de tratar, valores perdidos foram substituídos (última observação carregada ao final) e o nível de significância de 5%. RESULTADOS: A aderência ao tratamento foi de 57% (pelo menos três avaliações), 32% de perdas (uma avaliação). Não houve efeitos colaterais graves. A média de testes negativos foi 25,4% (31,2). Significante redução na intensidade e duração do craving foi observada em 25% da amostra. Nenhuma redução significativa na freqüência do craving foi observada em 7,1%. Aumento na freqüência foi observado em 10,7% e 82,1% não apresentaram nenhuma variação. Nenhuma variação estatisticamente significativa na Escala de Impulsividade Barratt ou na pontuação total foi encontrada no final da avaliação quando comparado à inicial. CONCLUSÃO: Mais ensaios clínicos placebo-controlados com o topiramato para dependentes de cocaína deveriam ser conduzidos a fim de avaliar a evidência preliminar
