Social, Clinical and Microbiological Differential Characteristics of Tuberculosis among Immigrants in Spain

BACKGROUND: To identify the differential tuberculosis (TB) characteristics within the immigrant population with respect to natives in Spain. METHODOLOGY/PRINCIPAL FINDINGS: A prospective cohort study design was implemented to examine the TB cases diagnosed and starting standard antituberculous treatment in Spain, between January 1st 2006 and March 31st 2007. A logistic regression analysis was performed to determine differential characteristics. 1,490 patients were included in the study population, 1,048 natives and 442 (29.7%) immigrants. According to the multivariate analysis, the following variables were significantly associated with immigrant TB cases: younger age (OR = 3.79; CI:2.16-6.62), living in group situation (OR = 7.61; CI:3.38-12.12), lower frequency of disabled (OR:0.08; CI:0.02-0.26) and retired (OR:0.21; CI:0.09-0.48) employment status, lower frequency of pulmonary disease presentation (OR = 0.47; CI:0.24-0.92), primary or emergency care admission (OR = 1.80; CI:1.05-3.06 and OR = 2.16; CI:1.36-3.45), drug resistance (OR = 1.86; CI:1.01-3.46), treatment default (OR:2.12; CI:1.18-3.81), lower frequency of alcohol and cigarette consumption (OR = 2.10; CI:1.42-3.11 and OR = 2.85; CI:2.10-3.87 respectively), more directly observed treatment (OR = 1.68; CI:1.04-2.69), and poor understanding of TB disease and its treatment (OR = 3.11; CI:1.86-5.20). The low percentage of primary MDR-TB in the native population (0.1% vs. 2.2% of immigrants) should be noted. CONCLUSIONS/SIGNIFICANCE: The differences show the need to introduce specific strategies in the management of TB within the immigrant population, including the improvement of social and work conditions

Epidemiological trends of HIV/HCV coinfection in Spain, 2015-2019

Altres ajuts: Spanish AIDS Research Network; European Funding for Regional Development (FEDER).Objectives: We assessed the prevalence of anti-hepatitis C virus (HCV) antibodies and active HCV infection (HCV-RNA-positive) in people living with HIV (PLWH) in Spain in 2019 and compared the results with those of four similar studies performed during 2015-2018. Methods: The study was performed in 41 centres. Sample size was estimated for an accuracy of 1%. Patients were selected by random sampling with proportional allocation. Results: The reference population comprised 41 973 PLWH, and the sample size was 1325. HCV serostatus was known in 1316 PLWH (99.3%), of whom 376 (28.6%) were HCV antibody (Ab)-positive (78.7% were prior injection drug users); 29 were HCV-RNA-positive (2.2%). Of the 29 HCV-RNA-positive PLWH, infection was chronic in 24, it was acute/recent in one, and it was of unknown duration in four. Cirrhosis was present in 71 (5.4%) PLWH overall, three (10.3%) HCV-RNA-positive patients and 68 (23.4%) of those who cleared HCV after anti-HCV therapy (p = 0.04). The prevalence of anti-HCV antibodies decreased steadily from 37.7% in 2015 to 28.6% in 2019 (p < 0.001); the prevalence of active HCV infection decreased from 22.1% in 2015 to 2.2% in 2019 (p < 0.001). Uptake of anti-HCV treatment increased from 53.9% in 2015 to 95.0% in 2019 (p < 0.001). Conclusions: In Spain, the prevalence of active HCV infection among PLWH at the end of 2019 was 2.2%, i.e. 90.0% lower than in 2015. Increased exposure to DAAs was probably the main reason for this sharp reduction. Despite the high coverage of treatment with direct-acting antiviral agents, HCV-related cirrhosis remains significant in this population

Nutrición parenteral domiciliaria en España 2018. Informe del Grupo de Nutrición Artificial Domiciliaria y Ambulatoria NADYA

Objetivo: comunicar los datos de nutrición parenteral domiciliaria (NPD) obtenidos del registro del grupo NADYA-SENPE (www.nadya-senpe.com) del año 2018. Material y métodos: análisis descriptivo de los datos recogidos de pacientes adultos y pediátricos con NPD en el registro NADYA-SENPE del 1 de enero al 31 de diciembre de 2018. Resultados: se registraron 278 pacientes (54, 7% mujeres), 23 niños y 255 adultos, procedentes de 45 hospitales españoles, lo que representa una tasa de prevalencia de 5, 95 pacientes/millón de habitantes/año 2018. El diagnóstico más frecuente en adultos fue “oncológico paliativo” (22, 0%), seguido de “otros”. En niños fue la enfermedad de Hirschsprung junto con la enterocolitis necrotizante, con cuatro casos (17, 4%). El primer motivo de indicación fue síndrome de intestino corto tanto en niños (60, 9%) como en adultos (35, 7%). El tipo de catéter más utilizado fue el tunelizado tanto en niños (81, 0%) como en adultos (41, 1%). Finalizaron 75 episodios, la causa más frecuente fue el fallecimiento (52, 0%) y el paso a vía oral (33, 3%). Conclusiones: el número de centros y profesionales colaboradores en el registro de pacientes que reciben NPD se mantiene estable, así como las principales indicaciones y los motivos de finalización de la NPD. Aim: To communicate home parenteral nutrition (HPN) data obtained from the HPN registry of the NADYA-SENPE group (www.nadya-senpe.  com) for the year 2018. Material and methods: Descriptive analysis of the data collected from adult and pediatric patients with HPN in the NADYA-SENPE group registry from January 1st, 2018 to December 31st, 2018.  Results: There were 278 patients from 45 Spanish hospitals (54.7% women), 23 children and 255 adults, which represent a prevalence rate of 5.95 patients/million inhabitants/year 2018. The most frequent diagnosis in adults was “palliative cancer” (22.0%), followed by “others”. In children it was Hirschsprung’s disease together with necrotizing enterocolitis, with four cases (17.4%). The first indication was short bowel syndrome in both children (60.9%) and adults (35.7%). The most frequently used type of catheter was tunneled in both children (81.0%) and adults (41.1%). Ending 75 episodes, the most frequent cause was death (52.0%) and change to oral feeding (33.3%). Conclusions: The number of centers and collaborating professionals in the registry of patients receiving HPN remains stable, as well as the main indications and reasons for termination of HPN

Active structures and geological hazards in the central sector of the Betic-Rif Cordillera and the Alboran Sea

X Congreso Geológico de España, 5-7 de julio 2021, Vitoria-Gasteiz.-- 1 page[EN] The recent geodynamic activity in the Betic-Rif Cordillera and the Alboran Sea is determined by the interaction of subduction processes with roll-back in the West and tectonic indentation in the East. The integration of sea and land data in the DAMAGE project characterizes the central area of interaction. At the northern end, the seismicity of the frontal region of Sierra de Cazorla is associated with incipient tectonic indentation. To the South, seismic and aseismic extensional faults of high and low angle interact in the Granada Basin. The active normal faults in the Campo de Dalías are connected with recent and new strike-slip faults that affect the Alboran Sea, being responsible of the 2016 Alhoceima earthquake (M 6.3). Towards the Rif, new areas of deformation in the Al Hoceima region are identified on blind faults with significant seismogenic activity in 1993 and 2004. These structures represent an important geological hazard related to slope instability and tsunami development in the Alboran Sea and in water reservoirs. The economic and social impact of this geological hazard should be considered and quantified[ES] La actividad geodinámica reciente en la Cordillera Bético-Rifeña y el Mar de Alborán está determinada por la interacción entre los procesos de subducción con roll-back en el Oeste y la indentación tectónica en el Este. La integración de datos en mar y tierra en el proyecto DAMAGE caracteriza la zona central de interacción. En el extremo septentrional, la sismicidad de la región frontal de Sierra de Cazorla está asociada a indentación tectónica incipiente. Hacia el Sur, en la Cuenca de Granada, interaccionan fallas extensionales sísmicas y asísmicas de alto y bajo buzamiento. Las fallas normales activas en el Campo de Dalías, están conectadas con fallas de salto en dirección neoformadas que afectan el Mar de Alborán, y son responsables del terremoto de Alhucemas de 2016 (M 6.3). Hacia el Rif se identifican nuevas zonas de deformación en Alhucemas sobre fallas ciegas con importante actividad sismogénica en 1993 y 2004. Estas estructuras tienen asociada una importante peligrosidad geológica relacionada con la estabilidad de los taludes y la generación de tsunamis en el Mar de Alborán y estabilidad de masas de agua en embalses, cuya incidencia económica y social se debe considerar y cuantificarPeer reviewe
