Tras comentar la metodología utilizada y explicitar los resultados obtenidos, exponemos cuales son las características de los puestos de trabajo del profesorado universitario y comparamos dichas características con las de otros puestos similares

La villa romana de Salar (Granada). El programa escultórico en contexto arqueológico

This work was carried out within the framework of the Project HAR2017-89004-P, sponsored by the Ministerio de Economia y Competitividad of the Government of Spain and with ERDF Funds (Fondos FEDER), and the Project PID2019-105294GB-100/AEI/10.13039/501100011033, sponsored by the Ministerio de Ciencia e Innovacion of the Government of Spain and with ERDF Funds(Fondos FEDER); as well as the Research Groups HUM 143 and HUM 402 (Plan Andaluz de Investigacion of the Junta de Andalucia). We thank the City Council of Salar (Granada) for supporting the systematic archaeological excavation project in villa Salar, approved bythe Junta de Andalucia (Consejeria de Cultura y Patrimonio Historico) as a General Research Project.During the last decade various excavation campaigns have taken place at the Roman villa of Salar (Granada, Spain), located in the province Baetica. The excavated sector corresponds to the area surrounding a large peristyle of the pars urbana. Presiding over the open courtyard on one of the shorter sides is a triclinium, which in turn is associated with a nymphaeum. The ambulacrum on the opposite side of the peristyle was also excavated, uncovering a mosaic pavement with an interesting hunting scene, as well as other rooms that open onto it. In this work, the typological and iconographic study of the sculptural program recovered is carried out. The sculptural assemblage consists of 1) two nymph sculptures discovered in the nymphaeum associated with the triclinium; and 2) a Capitoline type Venus statue, which possibly decorated another fountain located on the southern side of the peristyle. The archaeological context and petrographic analyses add to the study of the pieces, as well as the analysis of this sculptural program related to nymphaea and garden environments.Durante la última década se han desarrollado varias campañas de excavación en la villa romana de Salar (Granada, España), situada en la provincial romana de la Bética. El sector excavado corresponde a la pars urbana, articulada en torno a un gran peristilo central. Presidiendo uno de los lados cortos del patio abierto se sitúa el triclinium, asociado con un nymphaeum. El ambulacrum en el lado opuesto del peristilo ha sido también excavado, descubriéndose un pavimento de mosaico con una interesante escena de caza, así como otras habitaciones que abren a este patio. En este trabajo se aborda el estudio tipológico e iconográfico del programa escultórico de la villa. El conjunto está integrado por: dos esculturas de ninfas, descubiertas en el nymphaeum asociado con el triclinium; y 2) una estatua de Venus, tipo Capitolina, que posiblemente decorase otra fuente, localizada en el lado sur del peristilo. El contexto arqueológico y los análisis petrográficos se integran en el estudio de las piezas, así como el análisis del programa escultórico del nymphaeum y el jardín circundante.Spanish Government HAR2017-89004-PERDF Funds (Fondos FEDER)Spanish Government PID2019-105294GB-100/AEI/10.13039/501100011033ERDF Funds(Fondos FEDER) Junta de Andalucia HUM 143 HUM 40

The Poly I:C maternal immune stimulation model shows unique patterns of brain metabolism, morphometry, and plasticity in female rats

Introduction: Prenatal infections are associated with an increased risk of the onset of schizophrenia. Rodent models of maternal immune stimulation (MIS) have been extensively used in preclinical studies. However, many of these studies only include males, omitting pathophysiological features unique to females. The aim of this study is to characterize the MIS model in female rats using positron emission tomography (PET), structural magnetic resonance imaging (MR), and neuroplasticiy studies. Methods: In gestational day 15, Poly I:C (or Saline) was injected into pregnant Wistar rats to induce the MIS model. Imaging studies: [18F]-fluoro-2-deoxy-D-glucose-PET scans of female-offspring were acquired at post-natal day (PND) 35 and PND100. Furthermore, T2-MR brain images were acquired in adulthood. Differences in FDG uptake and morphometry between groups were assessed with SPM12 and Regions of Interest (ROI) analyses. Ex vivo study: The density of parvalbumin expressing interneurons (PV), perineuronal nets (PNN), and parvalbumin expressing interneurons surrounded by perineuronal nets (PV-PNN) were evaluated in the prelimbic cortex and basolateral amygdala using confocal microscopy. ROIs and neuroplasticity data were analyzed by 2-sample T-test and 2-way-ANOVA analyses, respectively. Results: A significant increase in brain metabolism was found in all animals at adulthood compared to adolescence. MIS hardly modified brain glucose metabolism in females, highlighting a significant hypometabolism in the thalamus at adulthood. In addition, MIS induced gray matter (GM) enlargements in the pituitary, hippocampus, substantia nigra, and cingulate cortex, and GM shrinkages in some thalamic nuclei, cerebelar areas, and brainstem. Moreover, MIS induced white matter shrinkages in the cerebellum, brainstem and corpus callosum, along with cerebrospinal fluid enlargements in the lateral and 4th ventricles. Finally, MIS reduced the density of PV, PNN, and PV-PNN in the basolateral amygdala. Conclusion: Our work showed in vivo the differential pattern of functional and morphometric affectation in the MIS model in females, as well as the deficits caused at the synaptic level according to sex. The differences obtained highlight the relevance of including both sexes in psychiatric research in order to consider their pathophysiological particularities and successfully extend the benefits obtained to the entire patient population.MS-M was supported by the Ministerio de Ciencia e Innovación, Instituto de Salud Carlos III (PI17/01766, BA21/0030); co-financed by European Regional Development Fund (ERDF), “A way to make Europe”; project PID2021_128862OB-I00 funded by MCIN/AEI/10.13039/501100011033/FEDER, UE; Centro de Investigación Biomédica en Red de Salud Mental (CIBERSAM; project number CB07/09/0031); Delegación del Gobierno para el Plan Nacional sobre Drogas (project number 2017/085); and Fundación Alicia Koplowitz.

Evaluation of a New Monoclonal Chemiluminescent Immunoassay Stool Antigen Test for the Diagnosis of Helicobacter pylori Infection: A Spanish Multicentre Study

The stool antigen test (SAT) represents an attractive alternative for detection of Helicobacter pylori. The aim of this study was to assess the accuracy of a new SAT, the automated LIAISON(R) Meridian H. pylori SA based on monoclonal antibodies, compared to the defined gold standard C-13-urea breath test (UBT). This prospective multicentre study (nine Spanish centres) enrolled patients >= 18 years of age with clinical indication to perform UBT for the initial diagnosis and for confirmation of bacterial eradication. Two UBT methods were used: mass spectrometry (MS) including citric acid (CA) or infrared spectrophotometry (IRS) without CA. Overall, 307 patients (145 naive, 162 with confirmation of eradication) were analysed. Using recommended cut-off values (negative SAT = 1.10) the sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 67%, 97%, 86%, 92% and 91%, respectively, obtaining an area under the receiver operating characteristic (ROC) curve (AUC) of 0.85. Twenty-eight patients, including seven false positives and 21 false negatives, presented a discordant result between SAT and UBT. Among the 21 false negatives, four of six tested with MS and 11 of 15 tested with IRS presented a borderline UBT delta value. In 25 discordant samples, PCR targeting H. pylori DNA was performed to re-assess positivity and SAT accuracy was re-analysed: sensitivity, specificity, positive predictive value, negative predictive value, accuracy and AUC were 94%, 97%, 86%, 99%, 97% and 0.96, respectively. The new LIAISON(R) Meridian H. pylori SA SAT showed a good accuracy for diagnosis of H. pylori infection

Effectiveness and Safety of the Switch from Remicade® to CT-P13 in Patients with Inflammatory Bowel Disease

BACKGROUND AND AIMS: To evaluate the clinical outcomes in patients with IBD after switching from Remicade® to CT-P13 in comparison with patients who maintain Remicade®. METHODS: Patients under Remicade® who were in clinical remission with standard dosage at study entry were included. The ''switch cohort'' [SC] comprised patients who made the switch from Remicade® to CT-P13, and the ''non-switch'' cohort [NC] patients remained under Remicade®. RESULTS: A total of 476 patients were included: 199 [42%] in the SC and 277 [58%] in the NC. The median follow-up was 18 months in the SC and 23 months in the NC [p < 0.01]. Twenty-four out of 277 patients relapsed in the NC; the incidence of relapse was 5% per patient-year. The cumulative incidence of relapse was 2% at 6 months and 10% at 24 months in this group. Thirty-eight out of 199 patients relapsed in the SC; the incidence rate of relapse was 14% per patient-year. The cumulative incidence of relapse was 5% at 6 months and 28% at 24 months. In the multivariate analysis, the switch to CT-P13 was associated with a higher risk of relapse (HR = 3.5, 95% confidence interval [CI] = 2-6). Thirteen percent of patients had adverse events in the NC, compared with 6% in the SC [p < 0.05]. CONCLUSIONS: Switching from Remicade® to CT-P13 might be associated with a higher risk of clinical relapse, although this fact was not supported in our study by an increase in objective markers of inflammation. The nocebo effect might have influenced this result. Switching from Remicade® to CT-P13 was safe

Ciencia y profesión : el farmacéutico en la historia

474 páginas. Versiones pdf / epubLas IV Jornadas Científicas de la Sociedad de Docentes Universitarios de Historia de la Farmacia (SDUHFE) se celebraron en la Sede de La Rábida en junio de 2016. Esta obra presenta diversas investigaciones y comunicaciones, con varias temáticas que pueden desglosarse en cuatro bloques: 1) En un primer grupo podemos considerar todos los capítulos que abordan la historia de los colegios farmacéuticos así como los avatares de la profesión. Se da cuenta en la provincia de Sevilla de las dificultades del Colegio de Farmacéuticos en el periodo de la Guerra Civil y la Posguerra (1936-1949), del proceso de colegiación obligatoria a partir de 1916, pinceladas históricas sobre los farmacéuticos cántabros del siglo XIX, del Colegio de Farmacéuticos de Filipinas a finales del XIX, de los conflictos de los farmacéuticos en las reuniones sanitarias de mitad del XX, y del papel de los farmacéuticos titulares en la potabilización de las aguas de consumo en Plentzia (Vizcaya). 2) Podemos destacar también todos los trabajos que giran en torno a diferentes medicamentos y productos farmacéuticos, entre ellos estudios históricos sobre piedras preciosas, medicamentos para tratar heridas, quina contra las tercianas, opio, alexifármacos, medicamentos homeopáticos, talidomida o curiosos productos como el Licor del Polo. 3) El papel de los laboratorios farmacéuticos como la Casa Nestlé durante la Guerra Civil española y el franquismo, diferentes laboratorios onubenses durante este mismo periodo, el papel del Instituto de Higiene Militar y la experimentación con insecticidas clorados sintéticos en la posguerra española, aglutinan el tercer cuerpo temático. 4) Finalmente, podemos destacar los trabajos que tienen una componente publicitaria, divulgadora y social entre los que cabe destacar el estudio del NO-DO y los diferentes noticieros y documentales sobre temas farmacéuticos que resultan muy ilustrativos. La propaganda farmacéutica desarrollada en la revista Matronas, el inventario del patrimonio farmacéutico catalán, junto a la percepción social de la farmacia a través de las fallas valencianas conforma este último grupo

Effectiveness of an intervention for improving drug prescription in primary care patients with multimorbidity and polypharmacy:Study protocol of a cluster randomized clinical trial (Multi-PAP project)

This study was funded by the Fondo de Investigaciones Sanitarias ISCIII (Grant Numbers PI15/00276, PI15/00572, PI15/00996), REDISSEC (Project Numbers RD12/0001/0012, RD16/0001/0005), and the European Regional Development Fund ("A way to build Europe").Background: Multimorbidity is associated with negative effects both on people's health and on healthcare systems. A key problem linked to multimorbidity is polypharmacy, which in turn is associated with increased risk of partly preventable adverse effects, including mortality. The Ariadne principles describe a model of care based on a thorough assessment of diseases, treatments (and potential interactions), clinical status, context and preferences of patients with multimorbidity, with the aim of prioritizing and sharing realistic treatment goals that guide an individualized management. The aim of this study is to evaluate the effectiveness of a complex intervention that implements the Ariadne principles in a population of young-old patients with multimorbidity and polypharmacy. The intervention seeks to improve the appropriateness of prescribing in primary care (PC), as measured by the medication appropriateness index (MAI) score at 6 and 12months, as compared with usual care. Methods/Design: Design:pragmatic cluster randomized clinical trial. Unit of randomization: family physician (FP). Unit of analysis: patient. Scope: PC health centres in three autonomous communities: Aragon, Madrid, and Andalusia (Spain). Population: patients aged 65-74years with multimorbidity (≥3 chronic diseases) and polypharmacy (≥5 drugs prescribed in ≥3months). Sample size: n=400 (200 per study arm). Intervention: complex intervention based on the implementation of the Ariadne principles with two components: (1) FP training and (2) FP-patient interview. Outcomes: MAI score, health services use, quality of life (Euroqol 5D-5L), pharmacotherapy and adherence to treatment (Morisky-Green, Haynes-Sackett), and clinical and socio-demographic variables. Statistical analysis: primary outcome is the difference in MAI score between T0 and T1 and corresponding 95% confidence interval. Adjustment for confounding factors will be performed by multilevel analysis. All analyses will be carried out in accordance with the intention-to-treat principle. Discussion: It is essential to provide evidence concerning interventions on PC patients with polypharmacy and multimorbidity, conducted in the context of routine clinical practice, and involving young-old patients with significant potential for preventing negative health outcomes.

Impacto de la pandemia de COVID-19 y la cuarentena en hombres que tienen sexo con hombres viviendo con VIH en Argentina

Introducción: Las personas que viven con VIH (PVV) tienen mayor riesgo de complicaciones de salud mental. Para mitigar la propagación del COVID-19 en nuestro país se estableció una cuarentena temprana. Estudiamos el impacto del estrés relacionado con COVID-19 y la cuarentena en hombres que tienen sexo con hombres que viven con VIH (HSHV) en Argentina. Materiales y métodos: Realizamos una encuesta anónima en abril-mayo de 2020. Se incluyeron PVV en seguimiento en una institución privada en Argentina. Se evaluaron la adherencia a medidas preventivas de COVID-19 y al tratamiento antirretroviral, el acceso a recursos, factores psicosociales y el consumo de sustancias durante la cuarentena. Este análisis se centró en los resultados de HSHV. Resultados: Entre 1336 participantes incluidos, 596 se autoreportaron HSHV (mediana de edad de 44 años, RIC 35-52). La adherencia a la cuarentena fue del 96,8%; la pérdida de empleo en el hogar 55,4%. Se observó interrupción en la obtención de medicamentos antirretrovirales en el 4,9% y el 29,9% reportó adherencia subóptima. Los problemas de salud mental fueron frecuentes: depresión (14,1%), soledad (15,6%) y ansiedad (20,2%). Conclusiones: Nuestro estudio evidenció alta adherencia a las medidas preventivas al inicio de la cuarentena y dificultades en el acceso a los servicios de salud. La pandemia de COVID-19 ha comprometido la economía del país; este estudio muestra su impacto en el acceso de los HSHV a recursos básicos. Dado que la salud mental de los HSHV ha sido afectada, la pandemia resalta la necesidad de una visión integral de la salud de nuestros pacientes.
