RESUMO
Background: The neurological symptoms of Long COVID (LC) and the impact of neuropsychological manifestations on people's daily lives have been extensively described. Although a large body of literature describes symptoms, validating this with objective measures is important. This study aims to identify and describe the effects of Long COVID on cognition, balance, and the retinal fundus, and determine whether the duration of symptoms influences cognitive impairment. Methods: This cross-sectional study involved LC volunteers with cognitive complaint from public health centers in northern Barcelona who participated between January 2022 and March 2023. This study collected sociodemographic characteristics, information on substance use, comorbidities, and clinical data related to COVID-19. We measured five cognitive domains using a battery of neuropsychological tests. Balance was assessed through posturography and retinal vascular involvement by retinography. Results: A total of 166 people with LC and cognitive complaints participated, 80.72% were women and mean age was 49.28 ± 8.39 years. The most common self-reported symptoms were concentration and memory deficit (98.80%), brain fog (82.53%) and insomnia (71.17%). The 68.67% presented cognitive deficit in at least one domain, with executive functions being the most frequent (43.98%). The 51.52% of the participants exhibited a dysfunctional pattern in balance, and 9.2% showed some alteration in the retina. There were no statistically significant differences between cognitive impairment and symptom duration. Conclusion: Our findings contribute to a more comprehensive understanding of the pathology associated with Long COVID. They highlight the diversity of self-reported symptoms, the presence of abnormal balance patterns, and some cognitive impairment. These findings underscore the necessity of addressing the clinical management of this condition in primary care through follow-up and the pursuit of multidisciplinary and comprehensive treatment.
RESUMO
OBJECTIVES: Identifying profiles of hospitalized COVID-19 patients and explore their association with different degrees of severity of COVID-19 outcomes (i.e. in-hospital mortality, ICU assistance, and invasive mechanical ventilation). The findings of this study could inform the development of multiple care intervention strategies to improve patient outcomes. METHODS: Prospective multicentre cohort study during four different waves of COVID-19 from March 1st, 2020 to August 31st, 2021 in four health consortiums within the southern Barcelona metropolitan region. From a starting point of over 292 demographic characteristics, comorbidities, vital signs, severity scores, and clinical analytics at hospital admission, we used both clinical judgment and supervised statistical methods to reduce to the 36 most informative completed covariates according to the disease outcomes for each wave. Patients were then grouped using an unsupervised semiparametric method (KAMILA). Results were interpreted by clinical and statistician team consensus to identify clinically-meaningful patient profiles. RESULTS: The analysis included nw1 = 1657, nw2 = 697, nw3 = 677, and nw4 = 787 hospitalized-COVID-19 patients for each of the four waves. Clustering analysis identified 2 patient profiles for waves 1 and 3, while 3 profiles were determined for waves 2 and 4. Patients allocated in those groups showed a different percentage of disease outcomes (e.g., wave 1: 15.9% (Cluster 1) vs. 31.8% (Cluster 2) for in-hospital mortality rate). The main factors to determine groups were the patient's age and number of obese patients, number of comorbidities, oxygen support requirement, and various severity scores. The last wave is also influenced by the massive incorporation of COVID-19 vaccines. CONCLUSION: Our study suggests that a single care model at hospital admission may not meet the needs of hospitalized-COVID-19 adults. A clustering approach appears to be appropriate for helping physicians to differentiate patients and, thus, apply multiple care intervention strategies, as another way of responding to new outbreaks of this or future diseases.

INTRODUCTION: The profiles of patients with COVID-19 have been widely studied, but little is known about differences in baseline characteristics and in outcomes between subjects with a ceiling of care assigned at hospital admission and subjects without a ceiling of care. The aim of this study is to compare, by ceiling of care, clinical features and outcomes of hospitalized subjects during four waves of COVID-19 in a metropolitan area in Catalonia. METHODS: Observational study conducted during the first (March-April 2020), second (October-November 2020), third (January-February 2021), and fourth wave (July-August 2021) of COVID-19 in five centers of Catalonia. All subjects were adults (> 18 years old) hospitalized with a proven SARS-CoV-2 infection and with therapeutic ceiling of care assessed by the attending physician at hospital admission. RESULTS: A total of 5813 subjects were analyzed. Subjects with a ceiling of care were mainly older (difference in median age of 20 years), with more comorbidities (Charlson index 3 points higher) and with fewer clinical signs at baseline than patients without a ceiling of care. Some features of their clinical profiles changed among waves. There were differences in treatments received during hospital admission across waves, but not between subjects with and without a ceiling of care. Subjects with a ceiling of care had a death incidence more than four times the death incidence of subjects a without a ceiling of care (risk ratio (RR) ranging from 3.5 in the first wave to almost 6 in the third and fourth). Incidence of severe pneumonia and complications for subjects with a ceiling of care was around 1.5 times the incidence in subjects without a ceiling of care. DISCUSSION: Analysis of hospitalized subjects with SARS-CoV-2 infection should be stratified according to therapeutic ceiling of care to avoid bias and outcome misestimation.
RESUMO
Antibiotic stewardship programs optimize the use of antimicrobials to prevent the development of resistance and improve patient outcomes. In this prospective interventional study, a multidisciplinary team led by surgeons implemented a program aimed at shortening the duration of antibiotic treatment <7 days. The impact of the intervention on antibiotic consumption adjusted to bed-days and discharges, and the isolation of multiresistant bacteria (MRB) was also studied. Furthermore, the surgeons were surveyed regarding their beliefs and feelings about the program. Out of 1409 patients, 40.7% received antibiotic therapy. Treatment continued for over 7 days in 21.5% of cases, and, as can be expected, source control was achieved in only 48.8% of these cases. The recommendations were followed in 90.2% of cases, the most frequent being to withdraw the treatment (55.6%). During the first 16 months of the intervention, a sharp decrease in the percentage of extended treatments, with R2 = 0.111 was observed. The program was very well accepted by surgeons, and achieved a decrease in both the consumption of carbapenems and in the number of MRB isolations. Multidisciplinary stewardship teams led by surgeons seem to be well received and able to better manage antibiotic prescription in surgery.
RESUMO
Surveillance colonoscopies focused to detect dysplasia are recommended to prevent colorectal cancer in patients with long-standing colonic inflammatory bowel disease (IBD). To date, histologic diagnosis and gradation of IBD-related dysplasia has been challenged by a high variability among pathologists. We aimed to analyze the observer characteristics that are correlated with concordance deviations in this diagnosis. Eight pathologists evaluated a set of 125 endoscopic biopsy samples with a representative distribution of nondysplastic and dysplastic lesions from long-standing IBD patients. Two rounds of diagnosis were carried out during a period of 18 months. The κ test was applied to analyze concordance. Pathologists were grouped on the basis of their experience. A subanalysis was performed by eliminating the highly prevalent nondysplastic samples, as well as an analysis after observers' grouping. Overall interobserver agreement was good (κ=0.73), with an even higher pairwise value (κ=0.86) as well as the intraobserver agreement values (best κ=0.85). After eliminating the highly prevalent nondysplastic samples, the interobserver agreement was still moderate to good (best overall κ=0.50; best paired κ=0.72). Notable differences were seen between the pathologists with a high-volume and low-volume practice (best overall κ=0.61 and 0.41, respectively). The agreement in the diagnosis of dysplasia in IBD endoscopic biopsies may have been undervalued over time. This is the first study evaluating pathologists' diagnostic robustness in this field. The results suggest that examining a large volume of samples is the key factor to increase the consistency in the diagnosis and gradation of IBD-related dysplasia.

BACKGROUND: We aimed to assess the effect of ageing and time since first heroin/cocaine use on cause-specific mortality risk and age disparities in excess mortality among heroin (HUs) and cocaine users (CUs) in Spain. METHODS: A cohort of 15,305 HUs and 11,905 CUs aged 15-49 starting drug treatment during 1997-2007 in Madrid and Barcelona was followed until December 2008. Effects of ageing and time since first heroin/cocaine use were estimated using a competing risk Cox model and the relative and absolute excess mortality compared to the general population through directly age-sex standardized rate ratios (SRRs) and differences (SRDs), respectively. RESULTS: Mortality risk from natural causes increased with time since first heroin use, whereas that from overdose declined after having peaked in the first quinquennium. Significant effects of time since first cocaine use were not identified, although fatal overdose risk seemed higher in CUs after five years. Mortality risk from natural causes (HUs and CUs), injuries (HUs), and overdoses (CUs) increased with age, the latter without reaching statistical significance. Crude mortality rates from overdoses and injuries remained very high at age 40-59 among both HUs (595 and 217 deaths/100,000 person-years, respectively) and CUs (191 and 88 deaths/100,000 person-years). SRDs from all and natural causes were much higher at age 40-59 than 15-29 in both HUs (2134 vs. 834 deaths/100,000 person-years) and CUs (927 vs. 221 deaths/100,000 person-years), while the opposite occurred with SRRs. CONCLUSION: The high mortality risk among HUs and CUs at all ages from both external and natural causes, and increased SRDs with ageing, suggest that high-level healthcare and harm reduction services should be established early and maintained throughout the lifetime of these populations.

BACKGROUND: Previous analyses of excess mortality in drug users compared with the general population have almost always been based on mortality ratios, reporting much higher figures in women than men. This study tests the hypothesis that being a heroin or cocaine user adds more death risk in women than men in Spain. METHODS: A retrospective cohort of 15,305 heroin users (HUs) and 11,905 cocaine users (CUs) aged 15-49 starting drug treatment in 1997-2007 was recruited in Spain and followed until December 2008 to determine vital status and cause of death. Excess mortality in men and women compared to the general population was assessed with directly age-standardized rate ratios (SRRs) and differences (SRDs). RESULTS: SRR was significantly higher in women than men for all causes (14.7 vs. 9.4), natural causes (8.7 vs. 6.2), overdose (331.6 vs. 163.9) and other external causes (46.9 vs. 11.8) among HUs; and for overdose (170.8 vs. 40.5) and other external causes (21.0 vs. 4.7) among CUs. However, the opposite happened with SRD for all causes (1294 vs. 1845 deaths/100,000 person-years), natural causes (675 vs. 1016 deaths/100,000 person-years) and overdose (331 vs. 619 deaths/100,000 person-years) among HUs, while no significant SRD gender disparities were observed among CUs. CONCLUSION: Compared with the general population, being a heroin user adds greater absolute risk in men than women, but this does not happen with cocaine users. Similar results would likely have been found in most published cohort studies if this indicator had been used; the exclusive use of relative indices of disparity as in previous meta-analysis can be extremely misleading.

In recent years, the immigrant population has substantially increased in Spain. However, there is a lack of information in the knowledge of alcohol abuse among Spanish immigrants. We describe the epidemiology of alcohol abuse among foreign-born immigrants versus Spanish natives. We carried out a cross-sectional study that uses data from the European Survey of Health on the General Population of Spain of 2009. A sample of 22,188 subjects was analyzed (of whom, 3,162 were foreign). Proxies of problematic alcohol consumption were the prevalence of excessive average consumption and the prevalence of excessive episodic consumption (binge drinking). Descriptive analysis of the population, determination of area of origin with major alcohol consumption and related factors for each kind of consumption, separating immigrant and native population, were performed. The immigrant profile was heterogeneous, though predominantly aged between 35 and 54, and were living with their family and working. 3.4% of immigrants and 3.2% of natives were considered excessive drinkers; 8.9% and 10%, respectively, reported binge drinking in the last year. Immigrants from Northern and Western Europe, and Latin America, Andean countries had significantly a higher report of frequent alcohol consumption and/or binge drinking compared to native. On the contrary, born in Africa was a protective factor. Unemployment was the most relevant related factor, being more important in the immigrant population. The excessive alcohol consumption in immigrants is dissimilar; the interventions must be adapted to their social situation, environments and areas of origin.
A pesar del gran incremento de la población inmigrante en los últimos años, su uso de alcohol está poco estudiado. Se describe la epidemiología del consumo de riesgo de alcohol en la población inmigrante residente en España, frente a la nativa. Se emplearon datos de 22188 respondentes a la Encuesta Europea de Salud de 2009, de los que 3162 eran extranjeros. Como indicadores de consumo problemático se usó la prevalencia de consumo excesivo promedio y el consumo excesivo episódico. Se realizaron análisis descriptivo de la población, determinación de zonas de procedencia con mayor consumo de alcohol y factores relacionados para cada tipo de consumo separando población inmigrante de autóctona. El perfil sociodemográfico del inmigrante fue heterogéneo, aunque predominantemente de entre 35 y 54 años, que vive en familia y trabaja. Se consideraron bebedores excesivos promedio al 3,4% de los inmigrantes por el 3,2% de los nativos, y bebedores excesivos episódicos en el último año el 8,9% frente al 10%. Los inmigrantes procedentes de Europa del Norte y del Oeste, y América latina, países andinos, fueron aquellos que presentaron mayores razones de prevalencia de bebedores de riesgo que la población nativa. Por el contrario, proceder de África fue un factor protector. De los factores relacionados con un mayor consumo, destaca el desempleo, siendo más relevante en la población inmigrante. El consumo excesivo de alcohol en inmigrantes es muy heterogéneo, debiendo adecuarse las intervenciones sobre el mismo a su situación social, diferentes entornos y áreas de procedencia.

BACKGROUND: The aim of the study was to estimate the lethality of opioid overdose among young heroin users. METHODS: A prospective community cohort study was conducted in Barcelona and Madrid, Spain. Participants included 791 heroin users aged 18-30 years who were followed up between 2001 and 2006. Fatal overdoses were identified by record linkage of the cohort with the general mortality register, while non-fatal overdoses were self-reported at baseline and follow-up interviews. The person-years (py) at risk were computed for each participant. Fatal and non-fatal overdose rates were estimated by city. Transition towards injection shortly before the overdose could not be measured. Overdose lethality (rate of fatal overdose in proportion to total overdose) and its 95% CI was estimated using Bayesian models. RESULTS: The adjusted rates of fatal and non-fatal opioid overdose were 0.7/100 py (95% CI: 0.4-1.1) and 15.8/100 py (95% CI: 14.3-17.6), respectively. The adjusted lethality was 4.2% (95% CI: 2.5-6.5). CONCLUSIONS: Four out of 100 opioid overdoses are fatal. These are preventable deaths that could be avoided before or after the overdose takes place. Resources are urgently needed to prevent fatal opioid overdose.

Alcohol affects the brain and most organs and systems, and its use is related to a large number of health problems. These include mental, neurological, digestive, cardiovascular, endocrine, metabolic, perinatal, cancerous, and infectious diseases, as well as intentional and non-intentional injuries. Physiopathological mechanisms still remain unraveled, though direct toxicity of ethanol and its metabolites, nutritional deficit and intestinal microbial endotoxin absorption have been suggested, all of which would be further modulated by use patterns and genetic and environmental factors. Individually it is difficult to precisely predict who will or will not suffer health consequences. At population level several disorders show a linear or exponential dose-response relationship, as is the case with various cancer types, hepatopathies, injuries, and probably risky behaviors such as unsafe sex. Other health problems such as general mortality in people above 45 years of age, ischemic disease or diabetes mellitus show a J-shaped relationship with alcohol use. The overall effect of alcohol on the global burden of disease is highly detrimental, despite the possible beneficial effect on cardiovascular disease. Large differences are found by country, age, gender, socioeconomic and other factors. Disease burden is mostly related with alcohol's capacity to produce dependence and with acute intoxication. Often alcohol also produces negative consequences for other people (violence, unattended family or work duties, etc) which are generally not taken into account when evaluating burden of disease. The aim of this study was to describe the main alcohol-related social and health harms, as well as their generating mechanisms, using secondary data sources.

El alcohol afecta al cerebro y a la mayoría de los órganos y sistemas y se relaciona con numerosos problemas sanitarios, incluyendo enfermedades mentales, neurológicas, digestivas, cardiovasculares, endocrinas y metabólicas, perinatales, cáncer, infecciones y lesiones intencionadas y no intencionadas. Los mecanismos fisiopatológicos aún no se comprenden bien, aunque se ha postulado toxicidad directa del etanol y de sus metabolitos, deficits nutricionales y absorción de endotoxinas microbianas intestinales, todo modulado por los patrones de consumo y factores genéticos y ambientales. A nivel individual no puede predecirse con precisión quien tendrá o no problemas. A nivel poblacional para muchos problemas, como varios tipos de canceres, hepatopatías, lesiones, y probablemente conductas de riesgo, como relaciones sexuales sin protección, se suele observar una relación dosis respuesta lineal o exponencial. Para otros, como mortalidad general en mayores de 45 años, enfermedades isquémicas o diabetes mellitus la relación es en forma de J. Su impacto sobre la carga global de enfermedad es enorme, incluso después de descontar los efectos beneficiosos sobre la enfermedad cardiovascular, con diferencias importantes según país, edad, genero, posición socioeconómica y otros factores. Buena parte de los danos se relacionan con su capacidad para producir dependencia y con la intoxicación aguda. A menudo genera también consecuencias negativas para otras personas (violencia, incumplimiento de responsabilidades familiares o laborales, molestias) que no suelen considerarse al evaluar la carga de enfermedad. El objetivo de este trabajo es describir los principales danos sociales y sanitarios relacionados con el consumo de alcohol y los mecanismos que los generan a partir de fuentes secundarias (AU)

AIM: To determine predictors of changes in amount of cocaine use among regular users outside treatment services. DESIGN: Longitudinal study-we estimated the proportion of subjects who increased or decreased cocaine use and assessed possible predictors related to these changes among a street-recruited cohort of young regular cocaine users (RCU). SETTING: Three Spanish cities: Barcelona, Madrid and Seville PARTICIPANTS: A total of 720 RCU aged 18-30 years not regularly using heroin were recruited in the community during 2004-06 (Itinere Project). Follow-up interviews (n = 501) were carried out at 12-24 months. MEASUREMENTS: The average amount of cocaine used weekly was calculated taking into account the number of days of use and the usual quantity (g/day). A multinomial logistic regression approach was used to investigate the association between changes in amount of cocaine use (i.e. difference exceeded 33.3% of baseline level) after 12-24 months, and baseline socio-demographic characteristics, nightlife, patterns of cocaine use and use of alcohol and other psychoactive drugs. FINDINGS: Cocaine use baseline average level was 2.14 g/week [95% confidence interval (CI) = 2.02-2.42]. It decreased in 71.5% of subjects and increased in 14.1%. In multinomial analysis, negative associations were found between decreasing cocaine use and high levels of alcohol consumption and using an increasing number of psychoactive drugs. Moreover, low education level, having used cocaine frequently in houses and reporting cocaine binges were associated with increasing cocaine use. CONCLUSIONS: A street-recruited cohort of cocaine users in Spain showed a significant reduction in cocaine use over a period of 12-24 months. High consumption of alcohol and increasing use of other psychoactive drugs decreased the probability of reducing cocaine use.

We assessed mortality risk factors and excess mortality compared to the general population in two Spanish sub-cohorts of 8,825 cocaine and heroin users (CHUs) and 11,905 only cocaine users (OCUs) aged 15-49 admitted to drug treatment. Heroin use (among all cocaine users), no-regular employment and drug injection (among CHUs and OCUs), daily cocaine use and previous drug treatment (among CUs), and death before 2005 and >10 years of heroin use (among CHUs) were clearly associated with higher mortality in Cox regression. Excess mortality was assessed by the directly standardized mortality rate ratio, which was higher in CHUs (14.3; 95% CI: 12.6-16.2) than CUs (5.1; 95% CI: 4.3-6.0) and in women than men, especially among OCUs (8.6; 95% CI: 7.5-10.0 vs. 3.5; 95% CI: 3.3-3.8); it decreased with age among CHUs, but did not decrease overall during 1997-2008. OCUs excess mortality was considerable and showed no signs of decline, suggesting the need for improved treatment and prevention interventions.

BACKGROUND/AIMS: Non-fatal opioid overdose (NFOO) and major depression (MD) are highly prevalent in heroin users. Many risk factors are known for NFOO, but studies in non-clinical samples on its relationship with MD are lacking. We aimed to examine this relationship in a street-recruited sample, controlling for potential well-known confounders. METHODS: A cross-sectional study in 452 heroin users street-recruited by chain referral methods in three Spanish cities. Eligibility criteria were: age≤30 years, heroin use at least 12 days in the last year and at least once in the last 3 months. Depression was assessed using the Composite International Diagnostic Interview. A precise definition of NFOO was used. Adjusted odds ratios (AORs) for the NFOO predictors were obtained by logistic regression. RESULTS: The prevalence of NFOO and MD in the last 12 months was 9.1 and 23.2%, respectively. After adjusting for potential confounders, NFOO and MD were significantly associated (AOR 2.2; 95% CI 1.01-4.74). Other associated factors were imprisonment (AOR 4.1; 95% CI 1.4-12.1), drug injection (AOR 6.7; 95% CI 2.4-18.4) and regular use of tranquillisers/sleeping pills (AOR 2.9; 95% CI 1.16-7). CONCLUSIONS: Drug and mental health treatment facilities should consider the relationship between MD and NFOO when contacting and treating heroin users. Imprisonment, drug injection and use of tranquillisers/sleeping pills are also risk factors for NFOO.

OBJECTIVE: To identify the profile of community-recruited regular cocaine users and the prevalence of recent depression and associated factors. METHOD: A cross-sectional study was carried out in 630 regular cocaine users who were not heroin consumers. Depression, social support and dependence were evaluated with the Composite International Diagnostic Interview, the Duke-Functional Social Support Questionnaire, and the Severity of Dependence Scale, respectively. RESULTS: The mean age was 23 years and 33% of users were women. The predominant profile of cocaine use was recreational-intense. Most (88%) participants had completed secondary education. The use of emergency services in the previous year was 45.9% and 7.8% were under drug-dependence/psychiatric treatment. The prevalence of depression was 14.6%. In the multivariate analysis, the factors associated with recent depression were female gender, homelessness, ketamine consumption, and less confidential support CONCLUSIONS: Regular cocaine users may require specific attention in general health services. Greater access to treatment for depression is needed among this group.

BACKGROUND: Published studies indicate that primary cocaine users (PCUs) have a mortality rate 4-8 times higher than their age-sex peers in the general population. Most PCUs are primary intranasal cocaine users, never-injectors and never-opioid users (PICUNINOs) and are usually underrepresented in cohort mortality studies. The aim is to estimate excess mortality in all PCUs and in the subgroups of never-opioid users and PICUNINOs in Spain. METHODS: 714 PCUs aged 18-30 were street-recruited in 2004-2006 in Spain and followed until 2010 to ascertain vital status. Drug use was self-reported at baseline and 1-2years later. Mortality was compared with that of the general population using standardized mortality ratios (SMRs). RESULTS: SMRs were 4.7 (95% CI: 2.4-9.0), 2.5 (95%CI: 0.8-7.8) and 3.1 (95% CI: 1.0-9.6), respectively, among all participants, never-opioid users and PICUNINOS when using only baseline data on drug use, and 1.2 (95% CI: 0.2-8.5) and 1.4 (95% CI: 0.2-9.9) among the latter two subgroups, when using baseline plus follow-up data. CONCLUSION: Short-term mortality in young Spanish PCUs is 5 times higher than in the general population. This excess mortality may largely be explained by a history of opioid use or the risk of starting such use.

El consumo de drogas es un problema de salud pública. Entre los consumidores la presencia concomitante de trastornos mentales y abuso de sustancias son comunes. Este artículo examina los trastornos psiquiátricos que presentan jóvenes consumidores de cocaína y heroína, medidos con la World Mental Health Composite International Diagnostic Interview (WMH-CIDI).Se realizó una encuesta transversal de entrada a una cohorte de 1.266 jóvenes (18-30 años), consumidores regulares de cocaína y no heroína (705) y de 561 consumidores de heroína reclutados fuera de los servicios de salud en Barcelona, Madrid y Sevilla. Para evaluar los trastornos mentales se utilizó el WMH-CIDI, para medir el grado de dependencia la Severity of Dependence Scale (SDS), y para evaluar el apoyo social se utilizó el Cuestionario de Apoyo Social Funcional Duke-UNC. Se diagnosticó un trastorno mental al 43% de la muestra. Los diagnósticos más frecuentes fueron la depresión (37,5%) y la fobia específica (6,8%). Durante los últimos 12 meses, la prevalencia de trastorno mental en el grupo de heroína (26.4%) fue mayor que en el de cocaína (21.7%). Las variables relacionadas con la morbilidad psiquiátrica en la cohorte de cocaína fueron: el mayor número de días de consumo, las condiciones de vida inestables y el bajo apoyo social. En la cohorte de heroína, el ganar dinero a través de actividades ilegales, mientras que el consumo moderado de alcohol actuó como factor protector para la patología mental. En ambas cohortes, la morbilidad se asoció a haber recibido tratamiento psiquiátrico/psicológico durante los últimos 12 meses. Este estudio muestra una prevalencia relativamente alta de morbilidad psiquiátrica en consumidores de cocaína y heroína reclutados en entornos no clínicos. Para el futuro, son necesarios estudios que examinen las diferencias entre los patrones de consumo de cocaína y heroína y su asociación con las enfermedades mentales (AU)
Drug abuse is a serious public health problem. Moreover, co-occurring mental health and substance abuse disorders are common among drug users. This paper examines psychiatric disorders of young cocaine and heroin users using the World Mental Health Composite International Diagnostic Interview (WMH-CIDI). A cohort of 1266 young (18-30 years) current regular cocaine (705) and heroin (561) users were recruited outside the health services in Barcelona, Madrid and Seville, Spain. The WMH-CIDI was used to evaluate mental disorders; the Severity of Dependence Scale (SDS) measured the degree of dependence; and the Duke-UNC Functional Social Support Questionnaire (FSSQ) assessed social support, in a cross sectional study design. About 43% was diagnosed with a lifetime mental disorder. The most common diagnoses were depression (37.5%) and specific phobia (6.8%). During the last 12 months, prevalence rates were also slightly higher in heroin group (26.4%) than in cocaine cohort (21.7%). Every day cocaine consumption, having unstable living conditions and low social support were variables highly associated with psychiatric morbidity in cocaine cohort. In heroin cohort, earning money through illegal activities was associated with psychiatric morbidity, while the moderate use of alcohol acted as a protective factor for mental pathology. Morbidity was associated to having received psychiatric/psychological treatment during the last 12 months in both cohorts. This study has shown a relatively high prevalence of psychiatric morbidity in cocaine and heroin users recruited in non-clinical settings. Future studies examining differences between cocaine and heroin patterns of consumption associated with mental diseases are necessary (AU)

Objetivos El uso sanitario del Índice Nacional de Defunciones (INDEF) está aumentando por su gratuidad y accesibilidad. Partiendo de hallazgos inesperados al cruzar dos cohortes de pacientes con el INDEF, se pretende valorar la calidad de la información de esta fuente. Métodos Los registros individuales de dos cohortes de tratados por drogas en Barcelona (n=19.974) y Madrid (n=17.557) se cruzaron con el INDEF y luego con el Instituto Nacional de Estadística (INE) para asignar el estado vital. Se obtuvieron la especificidad y la sensibilidad del INDEF en relación al INE, y estimaciones de la mortalidad con ambos sistemas. Se calculó también la subestimación de la mortalidad en el conjunto de España en el mismo periodo. Resultados Durante 1997-2008, en Madrid, la búsqueda independiente en el INDEF subestimó la mortalidad un 18,9% con respecto al INE. Una búsqueda individualizada posterior restringida a los muertos detectados en el INE pero no en el INDEF la redujo al 13,9%. En Barcelona, con búsqueda combinada (independiente más restringida), la subestimación fue del 3,3%. Durante 2001-2002 la subestimación con búsquedas combinadas llegó al 32,3% en Madrid y al 7,3% en Barcelona. La subestimación también se aprecia en el conjunto de la población española (1,8% en 1997-2008 y 9,3% en 2001-2002). Durante 1997-2008 la especificidad de las búsquedas independientes en el INDEF fue del 100%, pero su sensibilidad en Madrid fue sólo del 81%.ConclusionesLa calidad del INDEF es suficiente para muchos usos sanitarios, pero subestima la mortalidad con importantes variaciones temporoespaciales. Mejorar sus algoritmos de búsqueda, posibilitar tabulaciones on-line de los principales resultados, introducir controles de calidad y evaluarlo sistemáticamente, permitirían aumentar su calidad (AU)
Objective The use of the Spanish National Death Index (S-NDI) is increasing as it is free and easily accessible. Prompted by unexpected findings when linking two cohorts of patients with the S-NDI, this study was performed to evaluate the quality of mortality data from this source. Methods Individual records of two cohorts of persons admitted to drug abuse treatment in Barcelona (n=19,974) and Madrid (n=17,557) were linked with the S-NDI and then with the National Statistics Institute (NSI) to assign vital status. The sensitivity and specificity of the S-NDI in relation to the NSI and estimates of mortality with both systems were obtained. Underestimation of mortality by the S-NDI for the same period in the whole of Spain was also calculated. Results For Madrid, from 1997-2008, independent searches in the S-NDI underestimated mortality by 18.9% compared with the NSI. A subsequent individualized search limited to deaths detected by the NSI but not by the S-NDI reduced underestimation to 13.9%. For Barcelona, underestimation with a combined search (independent plus limited) was 3.3%. From 2001-2002, underestimation with combined searches reached 32.3% in Madrid and 7.3% in Barcelona. Underestimation was also seen in the general Spanish population (1.8% in 1997-2008 and 9.3% in 2001-2002). From 1997-2008, the specificity of independent searches in the S-NDI was 100%, but its sensitivity in Madrid was only 81%.ConclusionsThe quality of the S-NDI is good enough for many uses in the health sector, but this index underestimates mortality with substantial spatiotemporal variations. The quality of the S-NDI could be increased by improving its search algorithms, enabling on-line tabulations of the main results, and introducing quality controls and routine evaluations (AU)
