Abstract: Background Traffic related injuries are leading contributors to burden of disease worldwide. In developing countries a high proportion of them can be attributed to public transportation vehicles. Several mental disorders including alcohol and drug abuse, psychotic disorders, mental stress, productivity pressure, and low monetary income were found predictors of high rates of traffic related injuries in public transportation drivers. The goal of this study was to estimate the prevalence of common mental disorders in the population of public transportation drivers of buses and rickshaws in Lima, Peru. Methodology/Principal Findings Cross sectional study. A sample of bus and rickshaw drivers was systematically selected from formal public transportation companies using a snowball approach. Participants completed self-administered questionnaires for assessing major depressive episode, anxiety symptoms, alcohol abuse, and burnout syndrome. Socio demographic information was also collected. The analyses consisted of descriptive measurement of outcomes taking into account both between and within cluster standard deviation (BCSD and WCSD). A total of 278 bus and 227 rickshaw drivers out of 25 companies agreed to participate in the study. BCSD for major depressive episode, anxiety symptoms and burnout syndrome was not found significant (p>0.05). The estimated prevalence of each variable was 13.7% (IC95%: 10.7–16.6%), 24.1% (IC95%: 19.4–28.8%) and 14.1% (IC95%: 10.8–17.4%) respectively. The estimated prevalence of alcohol abuse was 75.4% (IC95%: 69–81.7%, BCSD = 12.2%, WCSD = 41.9%, intra class correlation (ICC): 7.8%). Conclusion Common mental disorders such as alcohol abuse, major depressive episode, anxiety symptoms and burnout syndrome presented higher rates in public transportation drivers than general population.

Abstract: Estudio que describe las características de los registros de pacientes con accidente cerebro vascular (ACV), como diagnóstico causante de hospitalización en el Hospital Nacional Cayetano Heredia entre los a os 2000 - 2009. Se obtuvieron 2225 registros de pacientes mayores de 18 a os, con ACV. De acuerdo con la CIE-10, 1071 tenían el diagnóstico de ACV isquémico, 554 ACV hemorrágico, 183 hemorragia subaracnoidea, 49 isquémico hemorrágico, 10 crisis isquémica transitorias y en 358 no fue posible especificar el tipo. Se registraron 352 muertes (19,6 %), la mayoría en los primeros tres días. La razón hombre/mujer fue 1,09; la edad promedio 64,1 ± 17,2 a os y la mediana del tiempo de hospitalización fue de nueve días. Las condiciones asociadas más frecuentes fueron hipertensión arterial, fibrilación auricular y diabetes mellitus tipo 2. La mortalidad descrita es la más alta informada en nuestro medio, es constante en todos los grupos de edad y mayor en mujeres. We performed a descriptive study taking on account the characteristics of the registries of the patients hospitalized at the Hospital Nacional Cayetano Heredia between the years 2000 and 2009 with stroke as hospitalization diagnosis. 2225 records were obtained from patients older than 18, with stroke. According to ICD-10, 1071 had diagnosis of ischemic stroke, 554 were hemorrhagic, 183 were subarachnoid hemorrhage, 49 were ischemic plus hemorrhagic, 10 were transient ischemic attack (TIA) and in 358 we were unable to specify the type of stroke. 352 deaths were recorded (19.6 %), most of them during the first 3 days. The male / female ratio was 1.09, the mean age 64.1 ± 17.2 years and the median length of hospital stay was 9 days. The most common associated conditions were high blood pressure, atrial fibrillation and type 2 diabetes mellitus. The mortality found is the highest reported in our country, constant in all age groups and higher in women.

Abstract: Background Depressive disorders are leading contributors to burden of disease in developing countries. Research aiming to improve their diagnosis and treatment is fundamental in these settings, and psychometric tools are widely used instruments to support mental health research. Our aim is to validate and compare the psychometric properties of the Spanish versions of the Center for Epidemiological Studies Depression Scale (CES-D) and the Zung Self-Rating Depression Scale (ZSDS). Methodology/Principal Findings A Spanish version of the CES-D was revised by 5 native Spanish speaking psychiatrists using as reference the English version. A locally standardized Spanish version of the ZSDS was used. These Spanish versions were administered to 70 patients with a clinical diagnosis of DSM-IV Major Depressive Episode (MDE), 63 without major depression but with clinical diagnosis of other psychiatric disorders (OPD), and 61 with no evidence of psychiatric disorders (NEP). For both scales, Cronbach's alpha (C-α) and Hierarchical McDonald Omega for polychoric variables (MD-Ω) were estimated; and receiver operating characteristics (ROC) analysis performed. For the CES-D and ZSDS scales, C-α was 0.93 and 0.89 respectively, while MD-Ω was 0.90 and 0.75 respectively. The area under the ROC curve in MDE+OPD was 0.83 for CES-D and 0.84 for ZSDS; and in MDE+NEP was 0.98 for CES-D and 0.96 for ZSDS. Cut-off scores (co) for the highest proportions of correctly classified (cc) individuals among MDE+OPD were ≥29 for CES-D (sensitivity (ss) = 77.1/specificity (sp) = 79.4%/(cc) = 78.2%) and ≥47 for ZSDS (ss = 85.7%/sp = 71.4%/cc = 78.9%). In the MDE+NEP, co were ≥24 for the CES-D (ss = 91.4%/sp = 96.7%/cc = 93.9%) and ≥45 for the ZSDS (ss = 91.4%/sp = 91.8%/cc = 91.6%). Conclusion Spanish versions of the CES-D and ZSDS are valid instruments to detect depression in clinical settings and could be useful for both epidemiological research and primary clinical settings in settings similar as those of public hospitals in Lima, Peru.

ROSAT-HRI detection of the Class I protostar YLW16A in the rho Ophiuchi dark cloud

Abstract: I analyze unpublished or partially published archival ROSAT data of the rho Ophiuchi dark cloud. This set of seven overlapping ROSAT HRI pointings, composed of eight ~one-hour exposures, detects mainly the X-ray brightest T Tauri stars of this star-forming region. Only two HRI sources are new X-ray sources, and their optical counterparts are proposed as new Weak T Tauri star candidates. Meanwhile the ROSAT HRI caught during just one exposure a weak X-ray source (maximum likelihood=10; SNR=4.1\sigma for Gaussian statistics) among a group of three embedded young stellar objects including two Class I protostars. Previous ROSAT PSPC, ASCA GIS observations, and as I argue here one Einstein IPC observation, have already detected an X-ray source in this area, but this higher angular resolution data show clearly that X-rays are emitted by the Class I protostar YLW16A. This is the second Class I protostar detected by the ROSAT HRI in this dark cloud. The determination of the intrinsic X-ray luminosity of this event, L_X[0.1-2.4 keV]=(9.4-450)*1E30 erg/s, critically depends on the source absorption estimate. Improvements will be obtained only by the direct determination of this parameter from fitting of Chandra and XMM-Newton spectra.
