A comparative evaluation of internal medicine wards in spain

Objective – This analysis investigates the functional and environmental quality of several internal medicine wards in Spain. Background – Despite the economic recession, the Spanish healthcare system has proven to be resilient. In the near future, Spain will be faced with the demographic challenge of an ever-ageing population. Further efforts should be made to ensure a sustainable and affordable healthcare system. The elderly population is the group that requires the highest rates of healthcare resources, especially in acute-care hospitals, with the maximum hospital attendances and the longest average length of stay. Since there is scientific evidence that links healthcare outcomes with design (evidence-based-design), one way of improving the efficiency of healthcare delivery is by enhancing the quality of existing internal medicine wards as it is usually the place where the elderly inpatients are cared for. Post-Occupancy- Evaluation (POE) tools have been used globally to assess the performance of existing buildings but little has been applied in the Spanish context. Research question – How well do existing internal medicine wards perform in relation to guidelines and research on functional and environmental quality? Methods – Both quantitative and qualitative methods have been used in this case study for the triangulation of data. Four internal medicine wards have been evaluated with the following methods: architectural layout analysis, photo analysis and a POE tool designed for the Spanish context (CURARQ-H). Results – Not surprisingly, the oldest ward scores lower than the most recent buildings. The analysis reveals that the patients’ area is the one that gets better grades while the access area scores the lowest marks. Further details on improvement measures are given for each ward area. Conclusion – Compared to Scandinavia, USA or Canada, healthcare architecture in Spain is being slow to embark on EBD. This evaluation method together with CURARQ-H tool could be an enabler for generating synergies between healthcare staff and architects in Spain and work as an accelerator in the use of EBD at a national level.publishedVersio

Evaluación de la arquitectura hospitalaria: unidad de neonatología

The pursuit of efficiency and quality is particularly relevant in healthcare architecture because its design has a direct impact on clinical outcomes. Within a hospital, the neonatal unit is the place where patients are most vulnerable to their surrounding environment. This study evaluates the design of two Spanish neonatal units using architectural layout analysis, photo analysis and the post-occupancy-evaluation tool CURARQ-UNeo, and compares these against national guidelines and principles based on the evidence-based design process. The results from these studies are used to identify areas for improvement in each unit. This kind of evaluation might enhance the progress of the evidence-based design process in Spain, with the aim of guiding project decisions that contribute towards improving the quality of life of neonates, their relatives and the staff in the neonatal unit.La búsqueda de la eficiencia y la calidad es especialmente relevante en la arquitectura sanitaria ya que su diseño tiene una repercusión directa en los resultados clínicos obtenidos. Dentro del hospital, la unidad de neonatología es el lugar donde se atiende a los pacientes más vulnerables al entorno que les rodea. Este estudio evalúa el diseño de dos unidades españolas en relación con las guías de diseño nacionales y las recomendaciones del proceso de diseño basado en evidencias a partir del análisis de sus plantas, fotografías y la herramienta de evaluación post-ocupacional CURARQ-UNeo. Los resultados identifican las posibles actuaciones de mejora para cada unidad. Este tipo de evaluación puede impulsar el avance del proceso de diseño basado en evidencias en España con la finalidad de que las decisiones del proyecto contribuyan a mejorar la calidad de vida de los neonatos, sus familiares y el personal de una unidad de neonatología

Novel potential predictive markers of sunitinib outcomes in long-term responders versus primary refractory patients with metastatic clear-cell renal cell carcinoma

Background: several potential predictive markers of efficacy of targeted agents in patients with metastatic renal cell carcinoma (mRCC) have been identified. Interindividual heterogeneity warrants further investigation. Patients and methods: multicenter, observational, retrospective study in patients with clear-cell mRCC treated with sunitinib. Patients were classified in two groups: long-term responders (LR) (progression-free survival (PFS)≥22 months and at least stable disease), and primary refractory (PR) (progressive disease within 3-months of sunitinib onset). Objectives were to compare baseline clinical factors in both populations and to correlate tumor expression of selected signaling pathways components with sunitinib PFS. Results: 123 patients were analyzed (97 LR, 26 PR). In the LR cohort, overall response rate was 79% and median duration of best response was 30 months. Median PFS and overall survival were 43.2 (95% confidence intervals[CI]:37.2-49.3) and 63.5 months (95%CI:55.1-71.9), respectively. At baseline PR patients had a significantly lower proportion of nephrectomies, higher lactate dehydrogenase and platelets levels, lower hemoglobin, shorter time to and higher presence of metastases, and increased Fuhrman grade. Higher levels of HEYL, HEY and HES1 were observed in LR, although only HEYL discriminated populations significantly (AUC[ROC]=0.704; cut-off=34.85). Increased levels of hsa-miR-27b, hsa-miR-23b and hsa-miR-628-5p were also associated with prolonged survival. No statistical significant associations between hsa-miR-23b or hsa-miR-27b and the expression of c-Met were found. Conclusions: certain mRCC patients treated with sunitinib achieve extremely long-term responses. Favorable baseline hematology values and longer time to metastasis may predict longer PFS. HEYL, hsa-miR-27b, hsa-miR-23b and hsa-miR-628-5p could be potentially used as biomarkers of sunitinib response

Novel potential predictive markers of sunitinib outcomes in long-term responders versus primary refractory patients with metastatic clear-cell renal cell carcinoma

Background: Several potential predictive markers of efficacy of targeted agents in patients with metastatic renal cell carcinoma (mRCC) have been identified. Interindividual heterogeneity warrants further investigation. Patients and methods: Multicenter, observational, retrospective study in patients with clear-cell mRCC treated with sunitinib. Patients were classified in two groups: long-term responders (LR) (progression-free survival (PFS)=22 months and at least stable disease), and primary refractory (PR) (progressive disease within 3-months of sunitinib onset).

ENE-COVID nationwide serosurvey served to characterize asymptomatic infections and to develop a symptom-based risk score to predict COVID-19

Objectives: To characterize asymptomatic SARS-CoV-2 infections and develop a symptom-based risk score useful in primary healthcare. Study design and setting: Sixty-one thousand ninty-two community-dwelling participants in a nationwide population-based serosurvey completed a questionnaire on COVID-19 symptoms and received an immunoassay for SARS-CoV-2 IgG antibodies between April 27 and June 22, 2020. Standardized prevalence ratios for asymptomatic infection were estimated across participant characteristics. We constructed a symptom-based risk score and evaluated its ability to predict SARS-CoV-2 infection. Results: Of all, 28.7% of infections were asymptomatic (95% CI 26.1-31.4%). Standardized asymptomatic prevalence ratios were 1.19 (1.02-1.40) for men vs. women, 1.82 (1.33-2.50) and 1.45 (0.96-2.18) for individuals <20 and ≥80 years vs. those aged 40-59, 1.27 (1.03-1.55) for smokers vs. nonsmokers, and 1.91 (1.59-2.29) for individuals without vs. with case contact. In symptomatic population, a symptom-based score (weights: severe tiredness = 1; absence of sore throat = 1; fever = 2; anosmia/ageusia = 5) reached standardized seroprevalence ratio of 8.71 (7.37-10.3), discrimination index of 0.79 (0.77-0.81), and sensitivity and specificity of 71.4% (68.1-74.4%) and 74.2% (73.1-75.2%) for a score ≥3. Conclusion: The presence of anosmia/ageusia, fever with severe tiredness, or fever without sore throat should serve to suspect COVID-19 in areas with active viral circulation. The proportion of asymptomatics in children and adolescents challenges infection control.The ENE-COVID study was supported by the Spanish Ministry of Health, the Institute of Health Carlos III, and the Spanish National Health System.

SARS-CoV-2 viral load in nasopharyngeal swabs is not an independent predictor of unfavorable outcome

The aim was to assess the ability of nasopharyngeal SARS-CoV-2 viral load at first patient’s hospital evaluation to predict unfavorable outcomes. We conducted a prospective cohort study including 321 adult patients with confirmed COVID-19 through RT-PCR in nasopharyngeal swabs. Quantitative Synthetic SARS-CoV-2 RNA cycle threshold values were used to calculate the viral load in log10 copies/mL. Disease severity at the end of follow up was categorized into mild, moderate, and severe. Primary endpoint was a composite of intensive care unit (ICU) admission and/or death (n = 85, 26.4%). Univariable and multivariable logistic regression analyses were performed. Nasopharyngeal SARS-CoV-2 viral load over the second quartile (≥ 7.35 log10 copies/mL, p = 0.003) and second tertile (≥ 8.27 log10 copies/mL, p = 0.01) were associated to unfavorable outcome in the unadjusted logistic regression analysis. However, in the final multivariable analysis, viral load was not independently associated with an unfavorable outcome. Five predictors were independently associated with increased odds of ICU admission and/or death: age ≥ 70 years, SpO2, neutrophils > 7.5 × 103/µL, lactate dehydrogenase ≥ 300 U/L, and C-reactive protein ≥ 100 mg/L. In summary, nasopharyngeal SARS-CoV-2 viral load on admission is generally high in patients with COVID-19, regardless of illness severity, but it cannot be used as an independent predictor of unfavorable clinical outcome

Deciphering the quality of SARS-CoV-2 specific T-cell response associated with disease severity, immune memory and heterologous response

SARS-CoV-2 specific T-cell response has been associated with disease severity, immune memory and heterologous response to endemic coronaviruses. However, an integrative approach combining a comprehensive analysis of the quality of SARS-CoV-2 specific T-cell response with antibody levels in these three scenarios is needed. In the present study, we found that, in acute infection, while mild disease was associated with high T-cell polyfunctionality biased to IL-2 production and inversely correlated with anti-S IgG levels, combinations only including IFN-γ with the absence of perforin production predominated in severe disease. Seven months after infection, both non-hospitalised and previously hospitalised patients presented robust anti-S IgG levels and SARS-CoV-2 specific T-cell response. In addition, only previously hospitalised patients showed a T-cell exhaustion profile. Finally, combinations including IL-2 in response to S protein of endemic coronaviruses were the ones associated with SARS-CoV-2 S-specific T-cell response in pre-COVID-19 healthy donors’ samples. These results could have implications for protective immunity against SARS-CoV-2 and recurrent COVID-19 and may help for the design of new prototypes and boosting vaccine strategies.NIH (contract to AS, DW), Grant/AwardNumber: 75N9301900065; “Contratación de Personal Investigador Doctor”supported by the European Social Fund and Junta de Andalucía (PAIDIDOCTOR- Convocatoria 2019-2020 toFJO, SB); Instituto de Salud Carlos III,Fondos FEDER.

Altimetry for the future: Building on 25 years of progress

In 2018 we celebrated 25 years of development of radar altimetry, and the progress achieved by this methodology in the fields of global and coastal oceanography, hydrology, geodesy and cryospheric sciences. Many symbolic major events have celebrated these developments, e.g., in Venice, Italy, the 15th (2006) and 20th (2012) years of progress and more recently, in 2018, in Ponta Delgada, Portugal, 25 Years of Progress in Radar Altimetry. On this latter occasion it was decided to collect contributions of scientists, engineers and managers involved in the worldwide altimetry community to depict the state of altimetry and propose recommendations for the altimetry of the future. This paper summarizes contributions and recommendations that were collected and provides guidance for future mission design, research activities, and sustainable operational radar altimetry data exploitation. Recommendations provided are fundamental for optimizing further scientific and operational advances of oceanographic observations by altimetry, including requirements for spatial and temporal resolution of altimetric measurements, their accuracy and continuity. There are also new challenges and new openings mentioned in the paper that are particularly crucial for observations at higher latitudes, for coastal oceanography, for cryospheric studies and for hydrology. The paper starts with a general introduction followed by a section on Earth System Science including Ocean Dynamics, Sea Level, the Coastal Ocean, Hydrology, the Cryosphere and Polar Oceans and the ‘‘Green” Ocean, extending the frontier from biogeochemistry to marine ecology. Applications are described in a subsequent section, which covers Operational Oceanography, Weather, Hurricane Wave and Wind Forecasting, Climate projection. Instruments’ development and satellite missions’ evolutions are described in a fourth section. A fifth section covers the key observations that altimeters provide and their potential complements, from other Earth observation measurements to in situ data. Section 6 identifies the data and methods and provides some accuracy and resolution requirements for the wet tropospheric correction, the orbit and other geodetic requirements, the Mean Sea Surface, Geoid and Mean Dynamic Topography, Calibration and Validation, data accuracy, data access and handling (including the DUACS system). Section 7 brings a transversal view on scales, integration, artificial intelligence, and capacity building (education and training). Section 8 reviews the programmatic issues followed by a conclusion

MAREJADAS RURALES Y LUCHAS POR LA VIDA, VOL. II: CONFLICTOS SOCIOTERRITORIALES Y POR RECURSOS NATURALES

Volumen 2. Conflictos socioterritoriales y por recursos naturales, coordinado por: Rosalía López Paniagua, Dante Ariel Ayala Ortiz y Armando Contreras Hernández, constituido por 19 trabajos, divididos en tres secciones. La primera titulada Tierra: tenencia y cultivos transgénicos, contiene 6 trabajos, que abordan el persistente conflicto por la tenencia de la tierra y la producción de soya y maíz transgénico y la asociada acumulación del capital por despojo que caracteriza la agricultura transgénica en México, pero también formas de resistencia como la denuncia de contaminación transgénica en la Sierra Juárez de Oaxaca y las instituciones, actores y gestión en la Reserva de la Biósfera El Triunfo en la Sierra Madre de Chiapas. La segunda sección: Territorio: Explotación y envenenamiento, está compuesta por 5 trabajos que hacen referencia a los conflictos socioambientales derivados de la minería en manos de empresas nacionales y extranjeras omisas y gobiernos cómplices de las consecuencias depredadoras que generan en territorios campesinos e indígenas, debido a su asociación con el narcotráfico y por la contaminación del agua y la tierra que provocan, además de las consecuencias perversas en la salud humana y el entorno natural en diversas regiones del país. En la tercera y última sección, Agua: contaminación y escases, los 8 trabajos que la integran, analizan los conflictos socioterritoriales y luchas por la vida, en diversos estados del país. Se trata de investigaciones que estudian movimientos y conflictos sociales actuales en el campo mexicano, como son las luchas por la defensa del territorio y la defensa de la naturaleza, trabajos que abordan especialmente las disputas por el agua, y los problemas asociados del acceso, la escasez y la contaminación, no solo internos sino con empresas y con el Estado mismo que con la aprobación y aplicación de leyes y reglamentos, el despojo a los campesinos de su territorio en el que han trabajado y vivido por generaciones.INSTITUTO DE CIENCIAS AGROPECUARIAS Y RURALES (ICAR), UNIVERSIDAD DE GUADALAJARA, EL COLEGIO DE MICHOACÁN A.C., FACULTAD DE ESTUDIOS SUPERIORES ACATLÁN-UNAM, ECOSUR, CUCOSTA SUR GRANA, ASOCIACIÓN MEXICANA DE ESTUDIOS RURALES A.C
