Increased specificity of Fasciola hepatica excretory-secretory antigens combining negative selection on hydroxyapatite and salt precipitation.

A single and rapid method to obtain an antigenic fraction of excretory-secretory antigens (ESAs) from Fasciola hepatica suitable for serodiagnosis of fascioliasis is reported. The procedure consists in the negative selection of F. hepatica ESAs by hydroxyapatite (HA) chromatography (HAC; fraction HAC-NR) followed by antigen precipitation with 50% ammonium sulphate (AS) and subsequent recovery by means of a Millex-GV or equivalent filter (Fi-SOLE fraction). Tested in indirect ELISA, the Fi-SOLE antigens detected natural infections by F. hepatica with 100% sensitivity and 98.9% specificity in sheep, and 97.7% sensitivity and 97.7% specificity in cattle, as determined by ROC analysis. The SDS-PAGE and proteomic nano-UHPLC-Tims-QTOF MS/MS analysis of fractions showed that the relative abundance of L-cathepsins and fragments thereof was 57% in fraction HAC-NR and 93.8% in fraction Fi-SOLE. The second most abundant proteins in fraction HAC-NR were fatty-acid binding proteins (11.9%). In contrast, free heme, and heme:MF6p/FhHDM-1 complexes remained strongly bond to the HA particles during HAC. Interestingly, phosphorylcholine (PC)-bearing antigens, which are a frequent source of cross-reactivity, were detected with an anti-PC mAb (BH8) in ESAs and fraction HAC-NR but were almost absent in fraction Fi-SOLE.

Bayesian hierarchical modelling of the geospatial distribution of fasciolosis in dairy cattle and the impact on production: Application to the main milk-producing region (Galicia) in Spain.

Fasciolosis caused by Fasciola hepatica is a common parasitic infection among cattle in many countries. Although infected adult cows rarely show overt clinical signs, milk production may be impaired. Thus, significant production losses may occur in dairy herds with a high prevalence of fasciolosis. In this study, Bayesian hierarchical modelling was used to estimate the geospatial distribution of dairy cattle fasciolosis and its impact on milk production. The study was conducted in Galicia, the main milk producing region in Spain and a geographically heterogeneous area. The aims were: 1) to model the geospatial distribution of fasciolosis in dairy herds in the study area, 2) to identify clusters of herds with a high prevalence of fasciolosis, and 3) to assess the effect of fasciolosis on milk yield and quality. A large number of dairy cattle farms (n = 4907), of which 1660 provided production records, were surveyed. Fasciola infection status was determined by applying the MM3-SERO ELISA test to bulk tank milk samples. A high probability of infection was predicted in several zones, particularly in the centre, northeast and southeast of Galicia. Conversely, the predicted probability was very low in some parts of the northwest of the region. Infections with high within-herd prevalence (> 25% lactating cows infected) predominated. High within-herd prevalence was associated with loss of milk production (-1.387 kg/cow/ day, on average). No association between Fasciola infection and either milk fat or protein content was observed. This study has generated the first maps of the spatial distribution of the probability of Fasciola infection in dairy cattle herds in Galicia. The maps presented here can be used for reference purposes, enabling the design of better targeted fasciolosis control programmes in the region. Use of Bayesian hierarchical statistical analysis enabled us to ascertain the uncertainty of the predictions and to account for the spatial autocorrelation in the data. It also enabled us to generate maps showing the residual spatial variation in milk production, a topic that may deserve more detailed study.

Association between e-cigarette and conventional cigarette use among Spanish adolescents. / Asociación entre el uso de cigarrillos electrónicos y cigarrillos convencionales en adolescentes españoles.

In recent years, studies have highlighted the upward trend in electronic cigarette use among adolescents, as well as the potential of e-cigarette use to lead to subsequent conventional cigarette use. The study's aims were two-fold: 1) to examine the progression from e-cigarette use to conventional cigarette use; and 2) to analyze the differences in the severity of smoking pattern among dual users (i.e., e-cigarette and conventional cigarette use), cigarette-only smokers, and e-cigarette-only users in a Spanish adolescent population. Data were obtained from the ESTUDES, a representative survey of addictive behaviors of Spanish adolescents aged 14-18, which was comprised of 38,010 adolescents (Mage = 15.69; SD = 1.19; 51.35% females). Results indicate that lifetime e-cigarette use increased the prevalence of subsequent conventional cigarette use by 1.86 times (95% CI 1.74, 1.99), and the prevalence of conventional cigarette use in the last month by 2.38 times (95% CI 2.19, 2.58), independently of whether the e-cigarette contains nicotine or not. Dual users showed a higher percentage of daily smokers, and a greater number of cigarettes per day, a higher use of e-cigarettes with nicotine, and an earlier age of smoking onset. Regarding risk perception, e-cigarette-only users perceived both conventional tobacco and e-cigarettes as less harmful (all p-values < .001). These findings document the strength of association between e-cigarette and conventional cigarettes, and underscore the importance of developing legal restrictions and prevention strategies aimed at reducing e-cigarette use, which in turn would reduce tobacco use.

En los últimos años, algunos estudios han destacado la tendencia ascendente en el uso del cigarrillo electrónico entre adolescentes, así como el potencial para el posterior consumo de cigarrillos convencionales. Este estudio tuvo dos objetivos: 1) examinar la progresión del cigarrillo electrónico al cigarrillo convencional; y 2) analizar las diferencias en el patrón de gravedad del tabaquismo entre consumidores duales (i.e., cigarrillos electrónicos y convencionales), fumadores de cigarrillos y consumidores de cigarrillos electrónicos. Los datos se obtuvieron de la encuesta ESTUDES, una encuesta nacional que recoge información de conductas adictivas en adolescentes entre 14 y 18 años, la cual consta de 38 010 personas (Medad = 15,69; DT = 1,19; 51,35% mujeres). Los resultados indicaron que haber usado alguna vez un cigarrillo electrónico incrementó la probabilidad de un consumo posterior de cigarrillos 1,86 veces (IC 95% 1,74-1,99), y la probabilidad de consumir tabaco en el último mes 2,38 veces (IC 95% 2,19-2,58), independientemente de si los cigarrillos electrónicos contienen o no nicotina. Los consumidores duales mostraron un mayor porcentaje de fumadores diarios, un mayor número de cigarrillos al día, un mayor uso de cigarrillos electrónicos con nicotina y una edad de inicio más temprana. Con respecto a la percepción de riesgo, los adolescentes que han usado solo cigarrillos electrónicos percibían tanto el tabaco como los cigarrillos electrónicos como menos dañinos (todos los valores p < ,001). Estos hallazgos indican la fuerte asociación entre los cigarrillos electrónicos y los convencionales, y subrayan la importancia de desarrollar restricciones legales y estrategias preventivas dirigidas al cigarrillo electrónico, lo que reduciría a su vez el consumo de tabaco.

Protocol for a Trial Assessing the Efficacy of a Universal School-Based Prevention Program for Addictive Behaviors.

BACKGROUND: "Juego de Llaves" [ Set of Keys ] is a universal school-based prevention program for adolescents aged 12-15. It is aimed at reducing drug use and other addictive behaviors. This paper describes the full protocol for the evaluation design, instruments, randomization procedure, follow-ups, and primary outcomes. METHOD: Non-Randomized Control Cluster Trial in a set of Spanish secondary schools, with follow-ups at 12-, 24- and 36-months. Participants will be allocated to an experimental or control group. Using a digital application designed for the study, a battery of instruments will be used to assess addictive behaviors, sociodemographic variables, school climate and other transdiagnostic psychological variables. RESULTS: A pilot test will be carried out to test the implementation protocol and to calculate the sample size needed for outcome evaluation. After implementing the program, longitudinal statistical approaches will be used to report intervention efficacy and potential moderators and mediators. CONCLUSIONS: There is a lack of assessments on the effectiveness of school prevention programs, and this paper is expected to improve monitoring and ongoing evaluation in prevention.

Field evaluation of the enhanced MM3-COPRO ELISA test for the diagnosis of Fasciola hepatica infection in sheep.

Fasciolosis is a severe zoonosis responsible for major economic losses in livestock. The enhanced MM3-COPRO test (eMM3-COPRO) and the commercial version BIO K 201 (Bio-X Diagnostics, Rochefort, Belgium) are widely used as immunodiagnostic tools for the specific detection of coproantigens released by Fasciola during the late prepatent and patent stages of infection. However, performance of the eMM3-COPRO has never been evaluated under field conditions. To address this gap, a large number of ovine faecal samples, collected in a region where fasciolosis is endemic (Galicia, NW Spain), were analyzed. Two groups of sheep flocks were selected according to the Fasciola infection status: 'Fasciola-free' and 'Fasciola-infected' flocks. 'Fasciola-free' flocks were seronegative flocks with no history of fasciolosis detected by either coproscopy or necropsy in the last 5 years. Faecal samples from these sheep were used to calculate a cut-off value for infection (OD = 0.021). The cut-off was calculated using a bootstrap resampling method that enables estimation of the sampling distribution of the statistical parameters without making assumptions about the underlying data distribution. 'Fasciola-infected' flocks were characterized by high seroprevalence, a history of fasciolosis and periodical treatment with flukicides. Samples from these flocks were used to estimate the diagnostic accuracy of the eMM3-COPRO relative to coproscopy, which although limited by poor sensitivity is the only reference test available for diagnosing fasciolosis in vivo. To overcome this limitation, all animals classified positive by eMM3-COPRO were treated with triclabendazole and then retested. The eMM3-COPRO displayed higher sensitivity than coproscopy, as it detected coproantigens in all samples with positive coproscopy and in 12% of samples with negative coproscopy. The test also proved highly specific as coproantigens disappeared after the treatment. The eMM3-COPRO was less time consuming than coproscopy, particularly when the procedure involved numerous samples, and showed promise as a tool for monitoring flukicide efficacy.

CM-352 Efficacy in a Mouse Model of Anticoagulant-Associated Intracranial Hemorrhage.

BACKGROUND: Intracranial hemorrhage (ICH) is one of the major devastating complications of anticoagulation. Matrix metalloproteinase (MMP) inhibition has been proposed as a novel pharmacological approach for ICH treatment. OBJECTIVES: We evaluated the effects of CM-352 (MMP-fibrinolysis inhibitor) in an experimental ICH model associated with oral anticoagulants as compared with clinically used prothrombin complex concentrate (PCC). METHODS: ICH was induced by collagenase injection into the striatum of wild type (C57BL/6J) anticoagulated mice (warfarin or rivaroxaban) and Mmp10 -/- mice. Hematoma volume and neurological deficits were measured 24 hours later by diaminobenzidine staining and different behavioral tests. Circulating plasminogen activator inhibitor-1 (PAI-1) activity and interleukin-6 (IL-6) were measured in plasma samples and local inflammation was assessed by neutrophil infiltration. Finally, fibrinolytic effects of MMP-10 and rivaroxaban were evaluated by thromboelastometry and thrombin-activatable fibrinolysis inhibitor (TAFI) activation assays. RESULTS: Only PCC reduced hemorrhage volume and improved functional outcome in warfarin-ICH, but both PCC and CM-352 treatments diminished hemorrhage volume (46%, p < 0.01 and 64%, p < 0.001, respectively) and ameliorated functional outcome in rivaroxaban-ICH. We further demonstrated that CM-352, but not PCC, decreased neutrophil infiltration in the hemorrhage area at 24 hours. The effect of CM-352 could be related to MMP-10 inhibition since Mmp10 -/- mice showed lower hemorrhage volume, better neurological score, reduced IL-6 levels and neutrophil infiltration, and increased PAI-1 after experimental ICH. Finally, we found that CM-352 reduced MMP-10 and rivaroxaban-related fibrinolytic effects in thromboelastometry and TAFI activation. CONCLUSION: CM-352 treatment, by diminishing MMPs and rivaroxaban-associated fibrinolytic effects, might be a novel antihemorrhagic strategy for rivaroxaban-associated ICH.

The silent epidemic of lymphogranuloma venereum inside the COVID-19 pandemic in Madrid, Spain, March 2020 to February 2021.

Despite social distancing measures implemented in Madrid to prevent the propagation of SARS-CoV-2, a significant increase (57.1%; 28.5 to 38.5 cases/month) in cases of lymphogranuloma venereum was detected during the COVID-19 pandemic. This unusual scenario might have accelerated a shift in Chlamydia trachomatis (CT) epidemiology towards a higher proportion of L genotypes compared with non-L genotypes in CT-positive samples. Our data underscore the importance of surveillance of sexually transmitted infections during the pandemic, in particular among vulnerable populations.

No evidence of the clinical utility of single-item breakpoint to inform on tobacco demand in persons with substance use disorders.

RATIONALE: Behavioral economics has shown that single-item demand indicators are promising for capturing crucial aspects of nicotine reinforcement. It is suggested that brief breakpoint measures perform comparably to full-length demand indices in characterizing nicotine dependence; however, there have been no thorough assessments of their validity in clinical settings. OBJECTIVES: This study aimed to assess the validity and accuracy of a single-item breakpoint in informing on tobacco demand. METHODS: The sample consisted of 88 treatment-seeking smokers (% males = 70.5%) enrolled in substance use treatment. Participants provided data on smoking characteristics and completed the Fagerström Test for Nicotine Dependence, a single-item breakpoint measure and a 14-item cigarette purchase task (CPT). Hierarchical regressions were performed to compare the predictive capability of a single-item breakpoint and full-length tobacco demand indicators in determining nicotine addiction severity. RESULTS: The single-item breakpoint was significantly correlated with all indices stemmed from the CPT and both latent factors (all r values = .250-.368). Neither the brief breakpoint nor the full-length breakpoint significantly predicted nicotine dependence. After controlling for sex and smoking variables, factor 2 [ß = .565, p < .001] and its observed variables Omax [ß = .279, p = .006], 1/elasticity [ß = .340, p = .001], and intensity [ß = .551, p < .001], robustly predicted nicotine dependence severity. CONCLUSIONS: Our findings do not support the validity of single-item breakpoint measures for characterizing nicotine dependence in substance users. In a bid to foster translational research, brief demand measures capturing Omax, intensity, and elasticity should be developed.

Diferencias De Opinión Sobre El Uso De Los Test: Su Relación Con La Edad El Género Y El Sector Laboral / Differences In Opinions Regarding Testing Practices: The Role Of Age, Gender And Job Sector

Los test son importantes herramientas que ayudan a los profesionales de la Psicología a tomar decisiones sobre las personas. Para plantear acciones encaminadas a mejorar su uso, es importante determinar qué factores afectan a las opiniones que los psicólogos tienen sobre la práctica de los test. El presente estudio analiza el rol de tres factores: el género, la edad y el sector laboral (público vs. privado). Asimismo, se contrasta la opinión de los profesionales colegiados con las de los profesores universitarios que imparten asignaturas relacionadas con los test y su uso (Psicometría y Evaluación Psicológica o Psico-educativa). Tras analizar una muestra de 1.248 colegiados y 95 profesores de distintas universidades, los resultados muestran algunas diferencias de opinión en función de todos los factores considerados. Se analizan los resultados y sus implicaciones de cara al futuro. (AU)

Tests are important tools that help psychologists to make decisions about people. In order to propose actions aimed at improvingthe use of tests, it is important to determine what factors relate to psychologists’ opinions about testing practices. In this study weassess the role of three factors: gender, age, and job sector (public vs. private). In addition, we compare professionals’ opinions with those reported by professors of test-related subjects (psychometrics, and psychological and psycho-educational assessment). After analyzing a sample of 1,248 members of the Spanish Psychological Association and 95 professors from different universities, results show some differences in opinions across all the factors analyzed. Results and future challenges are discussed. (AU)

Does e-assessment always fit digital natives? A within-subject comparison between paperand tablet-based gambling assessments in adolescents / ¿La evaluación electrónica siempre se adapta a los nativos digitales? Una comparación intra-sujeto de la evaluación del juego de azar entre papel y tabletas electrónicas en adolescentes

Technological development has enabled the use of sophisticated methods for assessing multiple human behaviors. Despite the advantages of these newtechnologies, concerns exist regarding their equivalence with paper-based measures in epidemiological and health-related surveys. To date, literature on thistopic in relation to adolescents is virtually nonexistent. This study compares respondents’ performance on the same survey using both paper- and electronic tab-let-based assessment methods. A final sample of 135 adolescents (mean age 17.30 years, SD = 0.59; 56.3% males) consecutively completed two versions ofthe same survey on gambling behaviors and two questionnaires: The Gambling Motives Questionnaire (GMQ) and the South Oaks Gambling Screening-Re-vised for Adolescents (SOGS-RA). An ad-hoc questionnaire assessing participants’ satisfaction levels with each method was also used. The digital surveyyielded a lifetime, past year, and past month gambling prevalence of 54.1%, 45.2%, and 27.4%, respectively. Paper-based prevalence rates were 3.7-5.2%lower (all p < .092) and there were discrepancies in gambling activities. Although the reliability of the questionnaires was high in both formats, total scores wereconsistently higher in the paper-based format. GMQ and SOGS-RA intraclass correlations between versions ranged from .856-.884. Unexpectedly, studentspreferred the paper-based survey to the e-assessment (51.5% vs. 48.5%) and also enjoyed it more (31.3% vs 26.1%). Paper- and tablet-based surveys yielddifferent, albeit non-statistically significant, estimations of gambling behaviors even when the same participants were surveyed at one time. We recommend thatconsistency be routinely checked across assessment formats when adapting paper-and-pencil measures to digital formats.(AU)

El desarrollo tecnológico ha permitido el uso de métodos sofisticados de evaluación de múltiples comportamientos humanos.A pesar de los avances de estas nuevas tecnologías, existen preocupaciones sobre su equivalencia con las medidas de papel y lápiz en encuestas epidemio-lógicas y de salud. Hasta la fecha, la literatura en el tema en relación con los adolescentes es prácticamente inexistente. Este estudio compara el desempeñode los participantes sobre la misma encuesta utilizando métodos de evaluación de papel y lápiz y electrónicos. Una muestra de 135 adolescentes (edad media17.30 años, DT = 0.59; 56.3% hombres) completaron consecutivamente os versiones de la misma encuesta sobre conductas de juego y dos cuestionarios: elCuestionario de Motivos de Juego (GMQ) y el Cribado de Juego de South Oaks en su versión revisada para adolescentes (SOGS-RA). También se utilizó uncuestionario ad-hoc para evaluar el nivel de satisfacción de los participantes en cada método. La encuesta digital arrojó una prevalencia de juego vida, año y mesde 54,1%, 45,2%, y 27,4%, respectivamente. Las prevalencias en papel fueron 3,7-5,2% menores (todas p < ,092) y se mostraron discrepancias en las activi-dades de apuestas. A pesar de que la fiabilidad de los cuestionarios fue alta en ambos formatos, las puntuaciones totales fueron consistentemente más altas enel formato en papel. Las correlaciones intraclase en el GMQ y SOGS-RA oscilaban entre ,856 - ,884. Inesperadamente, los estudiantes preferían la encuestaen papel sobre el formato digital (51,5% vs. 48,5%) y también lo disfrutaron más (31,3% vs 26,1%).

Current Challenges for Fasciolicide Treatment in Ruminant Livestock.

Pharmacological treatment remains essential to control fasciolosis in areas where infection is endemic. However, there are major constraints to treating food-producing animals. Of particular concern is the lack of flukicides for treating early Fasciola infections in ruminant livestock in some countries. In addition, the information provided in package leaflets, particularly regarding withdrawal periods, is often incomplete, confusing, and/or contradictory. International regulatory bodies should harmonize the use of flukicides in livestock in favor of fairer, safer international trade. In addition, monitoring the efficacy of fasciolicides on farms is also essential to minimize the spread of drug-resistant populations of Fasciola. The current situation regarding flukicide formulations in the European Union and other, non-European countries is analyzed in this review paper.

Concurrent validity of the Alcohol Purchase Task for measuring the reinforcing efficacy of alcohol: an updated systematic review and meta-analysis.

BACKGROUND AND AIMS: An early meta-analysis testing the concurrent validity of the Alcohol Purchase Task (APT), a measure of alcohol's relative reinforcing value, reported mixed associations, but predated a large number of studies. This systematic review and meta-analysis sought to: (1) estimate the relationships between trait-based alcohol demand indices from the APT and multiple alcohol indicators, (2) test several moderators and (3) analyze small study effects. METHODS: A meta-analysis of 50 cross-sectional studies in four databases (n = 18 466, females = 43.32%). Sex, year of publication, number of APT prices and index transformations (logarithmic, square root or none) were considered as moderators. Small study effects were examined by using the Begg-Mazumdar, Egger's and Duval & Tweedie's trim-and-fill tests. Alcohol indicators were quantity of alcohol use, number of heavy drinking episodes, alcohol-related problems and hazardous drinking. APT indices were intensity (i.e. consumption at zero cost), elasticity (i.e. sensitivity to increases in costs), Omax (i.e. maximum expenditure), Pmax (i.e. price associated to Omax ) and breakpoint (i.e. price at which consumption ceases). RESULTS: All alcohol demand indices were significantly associated with all alcohol-related outcomes (r = 0.132-0.494), except Pmax , which was significantly associated with alcohol-related problems only (r = 0.064). The greatest associations were evinced between intensity in relation to alcohol use, hazardous drinking and heavy drinking and between Omax and alcohol use. All the tested moderators emerged as significant moderators. Evidence of small-study effects was limited. CONCLUSIONS: The Alcohol Purchase Task appears to have concurrent validity in alcohol research. Intensity and Omax are the most relevant indices to account for alcohol involvement.

El problema de la demarcación. Ciencia, Psicología y Psicoterapia / The demarcation problem. Science, Psychology and Psychotherapy

La polémica sobre la naturaleza científica de la Psicología tiene que ver necesariamente con la idea de ciencia y con los criterios que sirven para demarcarla. Se pasa revista a distintas ideas filosóficas sobre la ciencia con sus respectivos criterios de demarcación y se defiende la pluralidad de las ciencias, que no son reducibles unas a otras. La Psicología se concibe, así mismo, como una ciencia plural, en tensión entre las ciencias naturales y humanas, en la que el desarrollo histórico aún no ha llevado a un monismo teórico ni metodológico. Esta pluralidad es la fuente de la dificultad para desarrollar un criterio de demarcación tanto para la Psicología, como para la psicoterapia. Finalmente se analizan los problemas para establecer los criterios de demarcación para la Psicología y la psicoterapia, y se proponen los principales aspectos que se deben tener en cuenta a la hora de construirlos

The controversy over the scientific nature of psychology necessarily has to do with the idea of science and the criteria that demarcate it. Different philosophical ideas about science are reviewed with their respective demarcation criteria, and the plurality of the sciences, which are not reducible to each other, is supported. Psychology is also conceived as a plural science, in tension between the natural and human sciences, and in which historical development has not yet led to theoretical or methodological monism. This plurality is the source of the difficulty in developing a criterion of demarcation for both psychology and psychotherapy. Finally, the problems in establishing the demarcation criteria for psychology and psychotherapy are analyzed, and the main aspects that must be taken into account when constructing them are proposed

[The COVID-19 psychological helpline of the Spanish Ministry of Health and Spanish Psychological Association: characteristics and demand.] / El teléfono de asistencia psicológica por la COVID-19 del Ministerio de Sanidad y del Consejo General de la Psicología de España: Características y demanda.

Between March and May 2020, the Spanish Ministry of Health and the Spanish Psychological Association created the Psychological First Care Service (Servicio de Primera Ayuda Psicológica-SPAP), a national helpline designed to provide early psychological intervention to those people affected by COVID-19. This service attended more than 15,000 calls and carried out more than 11,000 interventions and 9,500 follow-ups with the general population, healthcare and other essential professionals and the patients and relatives of the sick or deceased. Results show that the majority of calls (45.7%) came from the Autonomous Community of Madrid, that women significantly used this service in a higher proportion than men (73.5%) and that the commonest age range among users was 40-59. 75.9% of consultations were related to psychological problems linked to anxiety and depressive symptoms. However, grief symptoms also stood out among the patients or relatives of the sick and deceased and, to a lesser extent, stress symptoms were prevalent in the group of professionals. These data show the usefulness of this early psychological care service and the need for similar resources to be implemented in coordination with or within the National Health System.

Entre marzo y mayo de 2020, el Ministerio de Sanidad y el Consejo General de la Psicología de España, pusieron en marcha el Servicio de Primera Ayuda Psicológica (SPAP), un servicio telefónico para toda España, diseñado para proveer atención psicológica temprana a las personas afectadas por la COVID-19. En el tiempo en que el servicio estuvo disponible, se gestionaron 15.170 llamadas, que condujeron a realizar 11.417 intervenciones psicológicas con personal sanitario y otros intervinientes, con enfermos y familiares de enfermos o fallecidos, y población general. Los resultados muestran que la mayoría de llamadas (45,7%) provenían de la Comunidad Autónoma de Madrid, que hubo significativamente más mujeres que utilizaron el servicio (73,5%) y que el rango de edad más común entre los usuarios era el de 40-59 años. El 75,9% de las consultas tuvo que ver con problemas psicológicos relacionados con sintomatología ansiosa y depresiva, aunque también destacaba la sintomatología de duelo entre los enfermos o familiares de enfermos y fallecidos y, en menor medida, la sintomatología de estrés en el grupo de intervinientes. Estos datos muestran la necesidad de este servicio de atención psicológica temprana y sugieren que recursos como este deberían implementarse de manera integrada en el Sistema Nacional de Salud.

Risk Factors for Mortality in Nursing Home Residents: An Observational Study.

Purpose: Identifying mortality risk factors in people living in nursing homes could help healthcare professionals to individualize or develop specific plans for predicting future care demands and plan end-of-life care in this population. This study aims to identify mortality risk factors in elderly nursing home (NH) residents, based on variables adapted to this environment, routinely collected and easily accessible to their healthcare professionals. Methods: A prospective, longitudinal, observational study of NH residents aged 65 years and older was carried out collecting sociodemographic, functional and cognitive status, nutritional variables, comorbidities, and other health variables. These variables were analyzed as mortality risk factors by Cox proportional hazard models. Results: A total of 531 residents (75.3% female; average age 86.7 years (SD: 6.6)) were included: 25.6% had total dependence, 53.4% had moderate to severe cognitive impairment, 84.5% were malnourished or at risk of malnutrition, and 79.9% were polymedicated. Risk of mortality (hazard ratio, HR) increased in totally dependent residents (HR = 1.52; p = 0.02) and in those with moderate or severe cognitive impairment ((HR = 1.59; p = 0.031) and (HR = 1.93; p = 0.002), respectively). Male gender (HR = 1.88; p < 0.001), age ≥80 years (HR = 1.73; p = 0.034), hypertension (HR = 1.53; p = 0.012), atrial fibrillation/arrhythmia (HR = 1.43; p = 0.048), and previous record of pneumonia (HR = 1.65; p = 0.029) were also found to be mortality drivers. Conclusion: Age and male gender (due to the higher prevalence of associated comorbidity in these two variables), certain comorbidities (hypertension, atrial fibrillation/arrhythmia, and pneumonia), higher functional and cognitive impairment, and frequency of medical emergency service care increased the risk of mortality in our study. Given their importance and their easy identification by healthcare professionals in nursing homes, these clinical variables should be used for planning care in institutionalized older adults.

Fingolimod in multiple sclerosis: profile of use in habitual practice.

OBJECTIVES: Fingolimod is the first oral drug indicated in monotherapy as a modifier of the course of very active relapsing-remitting multiple sclerosis (RRMS). The safety profile of fingolimod is well established in clinical trials and post-marketing studies. Our objective was to study the profile of fingolimod use in our health area. METHODS: A retrospective, observational, descriptive study was performed on the use of fingolimod in adult patients diagnosed with RRMS between January 2015 and February 2017 or until suspension of treatment in a reference hospital in north-western Spain. RESULTS: A total of 55 patients were included with a mean±SD time of treatment with fingolimod of 26±14.6 months (range 2-53). Thirteen patients permanently discontinued the treatment (10 due to outbreaks/disease progression and 3 due to adverse effects). No statistically significant differences were found between the percentage of patients who discontinued fingolimod and who had received only one previous treatment and those who had received two or more treatments. No cases of symptomatic bradycardia were reported. CONCLUSIONS: Fingolimod is a safe treatment for patients with multiple sclerosis.

Maternal immune response in the placenta of sheep during recrudescence of natural congenital infection of Neospora caninum.

In order to gain further insight into the pathogenesis and transmission of ovine neosporosis, the serological response of 13 naturally infected pregnant sheep was monitored. All sheep were euthanized upon the detection of a sharp increase in the level of specific antibodies against N. caninum in order to study the maternal immune response after the recrudescence of a chronic infection. Ten sheep were euthanized between 84 and 118 days of gestation, whereas the three remaining and three control not infected, pregnant sheep were euthanized at 135 days of gestation after no sharp increase in antibodies was detected. Vertical transmission was confirmed in 11 sheep by detection of N. caninum-DNA in at least one fetus, confirming recrudescence. Not all of fetuses showed pathologic microscopic lesions, however, multifocal non-purulent encephalitis was the main finding. Furthermore, nine out of the 11 vertical transmission positive sheep had lesions in placentomes (mainly multifocal necrotic foci), and the parasite was detected in eight out of 11 placentas by PCR and/or immunohistochemestry. The placentomes from sheep that suffered recrudescence showed an increased number of T lymphocytes CD3+ (CD4/CD8 < 1) and macrophages (MHC-II+), assessed by immunohistochemestry, together with an up-regulation of IFN-γ, IL-10, IL-4, TNFα, IL-2 and IL-18. IL-17 was only upregulated in the three infected sheep that did not have a sharp increase in antibody levels. In the sheep that showed fetal death at the time of euthanasia (n = 3) the placental microscopic lesions were more severe, the inflammatory infiltrate was higher, and the upregulation of cytokines was greater than in those sheep carrying viable fetuses. This study suggests that, similarly to bovine neosporosis, the time of gestation when recrudescence occurs determines the viability of the fetuses and, thus, seems to be related to the severity of lesions and immune response in the placenta. These results suggest that there might be a correlation, either as cause or as a consequence, between protection against vertical transmission of the parasite and a milder maternal serological response together with a high level of transcription of IL-17 in the placenta.
