Administrative prevalence of insomnia and associated clinical features in patients with addiction during active substance use.

INTRODUCTION: A bidirectional relation between substance use and insomnia has been described, although there are few studies examining insomnia in the population of people with addiction. The aim of this study was to describe the prevalence of insomnia during active substance use in patients with addiction and its associated clinical features. PATIENTS AND METHODS: Descriptive study in patients diagnosed with substance dependence disorder admitted to a Hospital Detoxification Unit. The existence of insomnia prior to admission was assessed using the Oviedo Sleep Questionnaire (OSQ). Demographic variables, consumptionrelated clinical variables, and diagnostic variables were collected and the SCID-I and -II (Structured Clinical Interview for DSM-IV) and CAADID (Conners’ Adult ADHD Diagnostic Interview for DSM-IV) were administered to evaluate the psychiatric diagnoses. Bivariate and multivariate analyses were made of the data. RESULTS: 481 patients (72.6% men, age 40.6±10.1 years) were enrolled. 64.3% of the patients reported insomnia during active substance use. The most common type of insomnia was fragmented nocturnal sleep (49.9%). The factors significantly associated with insomnia were polysubstance drug use, medical comorbidities (most notably, infectious diseases), anxiety disorder, personality disorder (particularly cluster C), a greater number of previous admissions for detoxication, and early age at onset of substance use. CONCLUSIONS: Insomnia is highly prevalent in patients with addiction during active use of the substance. Fragmented nocturnal sleep was the most common type of insomnia. Patients with addiction and comorbid anxiety disorder, medical comorbidity, and early onset of dependence were more likely to experience insomnia.

Prevalencia administrativa del insomnio en pacientes adictos durante el consumo activo de las sustancias y características clínicas asociadas / Administrative prevalence of insomnia and associated clinical features in patients with addiction during active substance use

Introducción. Se ha descrito una relación bidireccional entre el uso de sustancias y el insomnio, aunque existen escasos estudios sobre el insomnio en la población adicta. El objetivo es describir la prevalencia de insomnio durante el consumo activo de las sustancias en pacientes adictos y sus características clínicas asociadas. Pacientes y Metodología. Estudio descriptivo en pacientes diagnosticados de trastorno por dependencia de sustancias que ingresaron en una Unidad Hospitalaria de Desintoxicación. Se evaluó el insomnio previo al ingreso mediante el Cuestionario de Oviedo de Calidad del Sueño (COS). Se recogieron variables demográficas, clínicas referidas al consumo y diagnósticas y se realizaron las entrevistas SCID-I y II y CAADID para evaluar los diagnósticos psiquiátricos. Se realizó un análisis bivariante y multivariante de los datos. Resultados. Se incluyeron 481 pacientes (72,6% varones, edad 40,6±10,1 años). El 64,3% de los pacientes refirieron insomnio durante el consumo activo de la sustancia. El tipo de insomnio más frecuente fue el sueño nocturno fragmentado (49,9%). Los factores relacionados significativamente con el insomnio fueron policonsumidores, comorbilidad médica (destacando enfermedades infecciosas), trastorno de ansiedad, trastorno de personalidad (destacando cluster C), mayor número de ingresos de desintoxicación previos y edad de inicio del consumo más temprana. Conclusiones. El insomnio es muy prevalente en pacientes adictos durante el consumo activo de la sustancia. El sueño nocturno fragmentado es el tipo de insomnio más frecuente. Los pacientes adictos con trastorno de ansiedad comórbido, comorbilidad médica e inicio precoz de la dependencia tienen mayor probabilidad de presentar insomnio

Consumo de drogas entre los estudiantes de medicina: Una revisión de la literatura 1988-2013 / Substance Use among Medical Students: A Literature Review 1988-2013

El consumo de drogas legales e ilegales entre los estudiantes de medicina es un fenómeno parcialmente conocido. El objetivo de este trabajo es revisar la literatura internacional publicada, en los últimos 25 años, sobre el consumo de drogas legales e ilegales entre los estudiantes de medicina. Se realizó una búsqueda sistemática en MEDLINE y LILACS. Se evaluaron 106 manuscritos, que incluían 88.413 estudiantes de medicina. Se validaron 74.001 cuestionarios que representan el 83,7% de respuestas. La metodología y rigurosidad no son homogéneas en todas las publicaciones. Existen muchas variaciones regionales, siendo América y Europa las zonas en las que se han realizado más trabajos. Con la excepción del alcohol, en algunas zonas de occidente, los estudiantes de medicina consumen menos que los estudiantes universitarios en general y que la población general coetánea. Los consumos son principalmente de alcohol (24%), tabaco (17,2%) y cannabis (11,8%). También el consumo de fármacos hipnosedantes es frecuente (9,9%). El uso de estimulantes es del 7,7%, de cocaína es del 2,1%, siendo el de opiáceos muy reducido (0,4%). En algunas zonas de Latinoamérica hasta el 14,1% consumen inhalantes. Los estudiantes de los últimos años de carrera consumen más. El consumo de drogas es superior en los varones respecto a las mujeres, exceptuando los hipnosedantes. El consumo en estudiantes de medicina es un fenómeno que, por su prevalencia y posibles repercusiones, debe ser sistemáticamente evaluado

The use of legal and illegal substances by medical students is a phenomenon that is only partially known. The aim of this paper was to review the literature published internationally in the last 25 years about the use of legal and illegal substances by medical students. A systematic search was made of MEDLINE and LILACS. One hundred and six manuscripts were evaluated, which included a population of 88,413 medical students. We validated 74,001 questionnaires, which represented 83.7% of responses. The methodology and the rigor of its application are not the same in all the publications. There are many regional variations, most studies being made in America and Europe. With the exception of alcohol in some areas of the Western world, medical students use substances less than university students in general and the general population. The substances used are mainly alcohol (24%), tobacco (17.2%), and cannabis (11.8%). The use of hypnotic and sedative drugs also is common (9.9%). The rate of use of stimulants is 7.7% and of cocaine, 2.1%; opiate use being very low (0.4%). In some parts of Latin America, up to 14.1% use inhalants. Students in the last years of school have a higher rate of substance use. The use of substances, except for hypnotics and sedatives, is more common among men than women. The use of substances by medical students is a phenomenon that should be evaluated systematically due to its prevalence and potential impact

The influence of medical student gender and drug use on the detection of addiction in patients.

Little is known about medical students' interest in their training on drug addiction, their personal experience of consumption, and whether these aspects influence the detection of addiction in patients. Eighty-eight and one half percent considered that drug dependence issues are important to their professional future. The students report consuming alcohol (69%), cigarettes (19.5%), and illegal drugs (15.8%). Female students consumed fewer illegal drugs than the men (p =.022). Male students consumed more illegal drugs more frequently (p =.005), knew more consumers (p =.023), and those who drink alcohol consumed more illegal drugs than women who drink alcohol (p <.005). Drug and alcohol consumption among medical students may serve to normalize consumption and thus, may prevent the detection of addicts. It is important to educate and raise awareness about drugs and alcohol use, as this may influence detection. The focus should be particularly on the male group.

Lack of association between the LPR and VNTR polymorphisms of the serotonin transporter gene and cocaine dependence in a Spanish sample.

We genotyped the LPR and VNTR polymorphisms of the serotonin transporter gene in 504 cocaine-dependent patients and 508 controls. No association was detected with either polymorphism or with any haplotype combination. This study provided no evidence that these polymorphisms confer susceptibility to cocaine dependence in our sample.

[Risk factors for relapse in drug-dependent patients after hospital detoxification]. / Factores de riesgo de recaída en pacientes drogodependientes tras desintoxicación hospitalaria.

This work describes the profile of patients with relapse after hospital detoxification at six months of outpatient follow-up. An observational and prospective study was carried out in patients with substance-dependence disorder who were in the Detoxification Unit of the Vall d'Hebron University Hospital (Barcelona) between June 2009 and October 2010. Demographic, clinical, diagnostic and therapeutic variables were assessed. The criterion for relapse was a return to use of the substance that had led to hospitalization, and relapse was assessed by means of anamnesis, breathalyzer and/or urine analysis. Study variables were compared between patients who relapsed and those who did not. Of the 165 patients included, 108 patients finished the study (75% males, age 37.7 ± 9.5 years). A total of 72.2% had relapsed at the 6-month follow-up. Profile of patients who relapsed was: hospitalized for heroin detoxification (91.7% vs 8.3%, p = .038), polyconsumers (71.4% vs 32%, p = .05), high substance use in the hours prior to admission as a "farewell" (61.5% vs 39.5%, p = .04), patients with comorbidity (44.9% vs 23.3%, p = .04) and patients with affective disorders (19.5% vs 3.2%, p = .005). Detoxification from opiates and use in the hours prior to admission were associated independently with relapse at 6 months. There is a high percentage of relapses after hospital detoxification. Patients most likely to relapse are those dependent on opiates and those with compulsive use immediately prior to hospitalization.

Factores de riesgo de recaída en pacientes drogodependientes tras desintoxicación hospitalaria / Risk factors for relapse in drug-dependent patients after hospital detoxification

El presente trabajo pretende comparar las características entre los pacientes que recaen en el consumo y los que se mantienen abstinentes, a los seis meses de seguimiento ambulatorio tras terminar una desintoxicación hospitalaria. Se realizó un estudio observacional y prospectivo en pacientes con trastorno por dependencia de sustancias que ingresaron en la Unidad Hospitalaria de Desintoxicación del Hospital Universitario de Vall d’Hebron desde junio 2009 hasta octubre 2010. Durante el ingreso se recogieron variables demográficas, clínicas, diagnósticas y terapéuticas, y se realizó la entrevista SCID. Se consideró recaída el reinicio del consumo de la sustancia que fue motivo de ingreso y se evaluó por anamnesis y alcohotest y/o urinoanálisis. Las variables de estudio se compararon entre los pacientes que recayeron y los que no. De 165 pacientes incluidos, 108 finalizaron el estudio (75% varones, edad 37,7±9,5 años). 72,2% recayeron a los 6 meses. El perfil de pacientes que recayeron fue: pacientes que ingresaban para desintoxicación de heroína (91,7% vs 8,3%, p = .038), policonsumidores (71,4% vs 32%, p = .05), pacientes que consumían horas previas al ingreso a modo de despedida (61,5% vs 39,5%, p = .04), aquellos con comorbilidad médica (44,9% vs 23,3%, p = .04), y con trastornos afectivos comórbidos (19,5% vs 3,2%,p = .005). La desintoxicación de opiáceos y el consumo en horas previas se asociaron de forma independiente con la recaída a los 6 meses. Existe un alto porcentaje de recaídas tras desintoxicación hospitalaria. Ingresar para desintoxicación de opiáceos y/o consumir de forma compulsiva antes del ingreso, están relacionados con el mayor riesgo de recaída(AU)
