A systematic review of tuberculosis detection and prevention studies in prisons

Many studies have demonstrated that prisons are hotspots of tuberculosis disease and transmission. Despite this, it remains unclear which interventions are most effective at controlling tuberculosis in prisons. The objective was to determine the study designs used to investigate tuberculosis control in prisons, and the efficacy of interventions undertaken. This systematic review included published studies which had the aim of reducing TB incidence or prevalence, or increasing the number of people screened for active pulmonary tuberculosis in incarcerated populations. 2,429 records were identified, 178 full-text articles were screened, and 17 studies included. The majority of reports were before/after or prospective non-comparative studies. The median study duration was 23 months (range 5-144). The most common intervention was the introduction of active case finding (10/17 studies) but the timing and methods varied. Comparable pre- and post intervention outcome values were infrequently reported; therefore, it was not possible to quantify the efficacy of interventions. Data from studies of tuberculosis control in prisons is limited by a lack of: controlled interventions, reporting of pre-intervention methods, and comparable pre- and post-intervention outcomes. Prospective comparative trials of adequate duration to determine trends in incidence are necessary to understand which interventions are effective in prisons

Internal and relative motions of the Taurus and Ophiuchus star-forming regions

We investigate the internal and relative motions of the Taurus and Ophiuchus star-forming regions using a sample of young stars with accurately measured radial velocities and proper motions. We find no evidence for expansion or contraction of the Taurus complex, but a clear indication for a global rotation, resulting in velocity gradients, this suggests a common origin, possibly related to that of Gould's Belt.Comment: 2 figure

Una nueva asociación de matorral gipsófilo para el Sur de España (Provincia Bética)

El estudio de los matorrales gípsicos en el sur de España, revela la presencia de una comunidad diferente del resto de asociaciones descritas hasta el momento dentro de la alianza Lepidion subulati, al existir diferencias florísticas, ecológicas y biogeográficas. Por ello se propone la asociación Ononido angustifolii-Anthyllidetum cytisoidi nova, con un área subbética e hispalense, que se presenta en ambientes, secos y subhúmedos, sobre substratos gípsicos, los cuales dependiendo del ombrotipo se encuentran más o menos lavados, por lo que el matorral puede presentar más o menos gipsófitos estrictos. Asociación que se desarrolla sobre sustratos gípsicos, los cuales experimentan una pérdida de sales en ambientes seco-subhúmedos, por lo que esta nueva comunidad presenta un bajo porcentaje de gipsófilos estrictos frente a una mayor frecuencia de especies menos estrictas. Por lo que se propone la nueva alianza Resedo constrictae-Helianthemion syriacae nova de distribución ibérico-magrebíA study of the thickets growing on gypsum soils in the south of Spain reveals the presence of a community different from the other associations already described within the suballiance Lepidienion subulati as a result of the floristic, ecological and biogeographical differences. Therefore, we propose the association Ononido angustifolii-Anthyllidetum cytisoidi nova with a Subbetic and Hispalensean distribution. The association occurs in semiarid, dry and subhumid environments, on gypsum soils which, depending on the ombrotype, are more or less washed-out and, consequently, the thicket may comprise more o less strict gypsophytes. The association grows on gypsum soils which undergo salt deprivation in dry-subhumid environments. Thus, in this new community the percentage of strict gypsophilous taxa is low as compared to the number of less strict gypsophytes.

NIRS potential use for the determination of natural resources quality from dehesa (acorn and grass) in Montanera system for Iberian pigs.

NIRS technology has been used as an alternative to conventional methods to determinate the content of nutrients of acorns and grass from dehesa ecosystem. Dry matter (DM), crude fat (CF), crude protein (CP), starch, total phenolic compounds (TP), α-tocopherol, γ-tocopherol, fatty acids, neutral detergent fiber (NDF), total antioxidant activity (TAA) and total energy (TE) were determined by conventional methods for later development of NIRS predictive equations. The NIR spectrum of each sample was collected and for all studied parameters, a predictive model was obtained and external validated. Good prediction equations were obtained for moisture, crude fat, crude protein, total energy and γ-tocopherol in acorns samples, with high coefficients of correlation (1-VR) and low standard error of prediction (SEP) (1-VR=0.81, SEP=2.62; 1-VR=0.92, SEP=0.54; 1-VR=0.86, SEP=0.47; 1-VR=0.84, SEP=0.2; 1-VR=0.88, SEP=5.4, respectively) and crude protein, NDF, α-tocopherol and linolenic acid content in grass samples (1-VR=0.9, SEP=1.99; 1-VR=0.87, SEP=4.13; 1-VR=0.76, SEP=10.9; 1-VR=0.82, SEP=0.6, respectively). Therefore, these prediction models could be used to determinate the nutritional composition of Montanera natural resources

Valid group comparisons can be made with the Patient Health Questionnaire (PHQ-9): A measurement invariance study across groups by demographic characteristics

This is the final version. Available on open access from Public Library of Science via the DOI in this recordData Availability: The database is freely accessible from the website of the National Institute of Statistics of Peru, URL: http://iinei.inei.gob.pe/microdatos/ The information can be obtained by entering the survey query tab and selecting the ENDES data using the health module data. Only cross-sectional information from 2016 ENDES Health Questionnaire was used.Objective Analyze the measurement invariance and the factor structure of the Patient Health Questionnaire-9 (PHQ-9) in the Peruvian population. Method Secondary data analysis performed using cross-sectional data from the Health Questionnaire of the Demographic and Health Survey in Peru. Variables of interest were the PHQ-9 and demographic characteristics (sex, age group, level of education, socioeconomic status, marital status, and area of residence). Factor structure was evaluated by standard confirmatory factor analysis (CFA), and measurement invariance by multi-group CFA, using standard goodness-of-fit indices criteria for interpreting results from both CFAs. Analysis of the internal consistency (α and ω) was also pursued. Results Data from 30,449 study participants were analyzed, 56.7% were women, average age was 40.5 years (standard deviation (SD) = 16.3), 65.9% lived in urban areas, 74.6% were married, and had 9 years of education on average (SD = 4.6). From standard CFA, a one-dimensional model presented the best fit (CFI = 0.936; RMSEA = 0.089; SRMR = 0.039). From multi-group CFA, all progressively restricted models had ΔCFI<0.01 across almost all groups by demographic characteristics. PHQ-9 reliability was optimal (α = ω = 0.87). Conclusions The evidence presents support for the one-dimensional model and measurement invariance of the PHQ-9 measure, allowing for reliable comparisons between sex, age groups, education level, socioeconomic status, marital status, and residence area, and recommends its use within the Peruvian population.Universidad Católica los Ángeles de Chimbote (ULADECH-Católica)PSYCOPERU Peruvian Research Institute of Educational and Social Psycholog

Organic pollutants (PAHs) derived from the dump of the Thermal Power Station of Aliaga (Teruel)

The aim of this study was to determine if the soils, waters and plants from the Aliaga dump contained polycyclic aromatic hydrocarbons (PAHs) and their quantification.The results showed that PAHs concentrations in soils are in general higher than the reference levels from the Spanish legislation. Waters and plants contained PAHs but in low concentrations. The possible actions for remediation (photodegradation and bioremediation) seem to be unviable here because of the large volume of materials involved, although its use as an additive for the cement industry and derivatives can be considered. It is proposed that fluorantene in waters, and phenanthrene and benzo[ghi]perilene in soils be considered as pollutants as well as to study the incorporation of PAHs to plantsEl objetivo de este estudio fue determinar y cuantificar los hidrocarburos policíclicos aromáticos (PAHs) en los suelos, plantas y aguas de la Escombrera de Aliaga. La concentración de PAHs en las cenizas supera, en general, los valores establecidos en la legislación española. Las aguas y plantas contienen PAHs, aunque en concentraciones bajas. La remoción de los materiales para someterlos a fotodegradación y biorremediación es inviable debido al gran volumen de la escombrera, aunque se plantea su uso como aditivo en la fabricación de productos derivados del cemento. Se propone incluir el fenantreno y benzo[ghi]perileno en el la normativa de suelos, así como el naftaleno en la de aguas y la elaboración de una legislación sobre la incorporación de estos compuestos a las planta
