    Present paper describes some aspects of the restoration project recently undertaken in La Zarzuela Racecourse, designed by E. Torroja and Dominguez in 1934. Despite the good mechanical work of steel, it has started a deterioration process which has caused the corrosion of reinforcement by carbonation. It has been detected corrosion attack in some places due the breaking of the upper waterproofing membrane of the shell which enabled the water to remain long periods in the roof and therefore promoted corrosion of reinforcement. For the repair first an assessment of the degree of corrosion was made. The restoration project finally consisted in the injection of all the cracks in order to assure the joint work of the shell and the patching of the deteriorated zones. Profiting these works it was installed a monitoring system of corrosion sensors. Results of the recording are given in the paper

    Introducción: La reciente pandemia de COVID-19 ha representado la utilización por parte de los profesionales de la salud de diferentes equipos de protección individual (EPI), lo que ha dado lugar a la aparición de lesiones cutáneas asociadas a los mismos (LC-EPI). Conocer la epidemiología, las características y los factores relacionados con el uso de los diferentes tipos de EPI y la prevención y el tratamiento de las LC-EPI puede ser muy útil para comprender el alcance del problema y definir estrategias para su prevención y tratamiento en posibles pandemias futuras. Métodos: Estudio transversal realizado por el Grupo Nacional para el Estudio y Asesoramiento en Úlceras por Presión y Heridas Crónicas (GNEAUPP) en el ámbito geográfico del Estado español, mediante una encuesta autoadministrada utilizando un cuestionario de Google Forms. El universo de estudio fueron profesionales de la salud, de cualquier disciplina y nivel asistencial o tipo de institución que habían estado en contacto con pacientes o sospechosos de COVID-19 y habían utilizado EPI durante la primera ola de la pandemia de COVID-19 en España. Resultados: Se obtuvieron 2078 cuestionarios, el 75,5% de enfermeras, el 10,79% de técnicos en cuidados auxiliares de enfermería (TCAE) y el 6,6% de médicos. De los respondedores, el 84,7% eran mujeres y el 15,3% hombres con una edad media de 43,7 años. En el 18,2% de los casos, la institución del profesional contaba con un protocolo para la prevención de las LC-EPI, en el 10,2% el profesional no sabía si existía y en el 71,3% restante la institución no contaba con dicho protocolo. El 29,9% de los profesionales utilizaba siempre algún producto de prevención de LC-EPI y el 25,3% en ocasiones. El 52,4% de los encuestados informó haber presentado al menos una LC-EPI, de los cuales el 39% había presentado una, el 35,8% dos, el 14,3% tres, el 2,2% cuatro y el 8,6% más de cuatro. En relación con el tipo de lesiones, el 74,3% fueron definidas como lesiones por presión (LPP), el 11% como lesiones por fricción (LF), el 8,5% como lesiones combinadas o multicausales (LCMC) y el 6,1% como lesiones cutáneas asociadas a la humedad (LESCAH). La duración media de las lesiones incidentes fue de 11,6 días (9,7 días para las LPP, 10,2 días para las LF, 19,9 días para las LCMC y 19,4 días para las LESCAH). En el artículo se presenta información más detallada por tipo de dispositivo causante, tipología y gravedad de las lesiones por dispositivo, así como las medidas preventivas utilizadas.Introduction: The recent COVID-19 pandemic has represented the use by health care professionals (HCP) of different personal protective equipment (PPE), resulting in the appearance of skin injuries associated with PPE (PPE-SI). Knowing the epidemiology, characteristics and factors related to the use of different types of PPE and the prevention and treatment of PPE-SI can be very useful to understand the scope of the problem and to define strategies for its prevention and treatment in possible future pandemics. Methods: To this end, the GNEAUPP proposed the performance of a cross-sectional study, in the geographical area of the Spanish state, by means of a self-administered survey using a Google forms questionnaire. The study universe was HCP, from any discipline and from any level of care or type of institution with patients who have been in contact with COVID-19 patients or COVID-19 suspects and have used PPE during the first wave of the COVID-19 pandemic in Spain. Main results: We obtained 2078 questionnaires, 75.5% from nurses, 10.79% from nurse aids, and 6.6% from physicians. Of these, 84.7% were women and 15.3% were men with an average age of 43.7 years. In 18.2% of the cases the institution of the professional had a protocol for the prevention of PPE-SI, in 10.2% the professional did not know if it existed or not and in the remaining 71.3% the institution did not have such a protocol. 29.9% of the professionals always used some prevention product and 25.3% sometimes. 52.4% of respondents reported having submitted at least one PPE-SI, of which 39% had submitted one, 35.8% two, 14.3% three, 2.2% four and 8.6% more than four. In relation to PPE-SI, 74.3% were defined as pressure injuries (PI), 11% were friction injuries (FI), 8.5% were combined or multicausal injuries (CMCI) and 6.1% were skin injuries associated with moisture (MASI). The mean duration of incident injuries was 11.6 days (9.7 days for PI, 10.2 days for FI, 19.9 days for CMCI and 19.4 days for MASI). More detailed Information is presented in the paper by type of device causing, typology and severity of injuries per device as well as preventive measures used

    Background and purpose: Recent studies suggested an increased incidence of cerebral venous thrombosis (CVT) during the coronavirus disease 2019 (COVID-19) pandemic. We evaluated the volume of CVT hospitalization and in-hospital mortality during the 1st year of the COVID-19 pandemic compared to the preceding year. Methods: We conducted a cross-sectional retrospective study of 171 stroke centers from 49 countries. We recorded COVID-19 admission volumes, CVT hospitalization, and CVT in-hospital mortality from January 1, 2019, to May 31, 2021. CVT diagnoses were identified by International Classification of Disease-10 (ICD-10) codes or stroke databases. We additionally sought to compare the same metrics in the first 5 months of 2021 compared to the corresponding months in 2019 and 2020 (ClinicalTrials.gov Identifier: NCT04934020). Results: There were 2,313 CVT admissions across the 1-year pre-pandemic (2019) and pandemic year (2020); no differences in CVT volume or CVT mortality were observed. During the first 5 months of 2021, there was an increase in CVT volumes compared to 2019 (27.5%; 95% confidence interval [CI], 24.2 to 32.0; P<0.0001) and 2020 (41.4%; 95% CI, 37.0 to 46.0; P<0.0001). A COVID-19 diagnosis was present in 7.6% (132/1,738) of CVT hospitalizations. CVT was present in 0.04% (103/292,080) of COVID-19 hospitalizations. During the first pandemic year, CVT mortality was higher in patients who were COVID positive compared to COVID negative patients (8/53 [15.0%] vs. 41/910 [4.5%], P=0.004). There was an increase in CVT mortality during the first 5 months of pandemic years 2020 and 2021 compared to the first 5 months of the pre-pandemic year 2019 (2019 vs. 2020: 2.26% vs. 4.74%, P=0.05; 2019 vs. 2021: 2.26% vs. 4.99%, P=0.03). In the first 5 months of 2021, there were 26 cases of vaccine-induced immune thrombotic thrombocytopenia (VITT), resulting in six deaths. Conclusions: During the 1st year of the COVID-19 pandemic, CVT hospitalization volume and CVT in-hospital mortality did not change compared to the prior year. COVID-19 diagnosis was associated with higher CVT in-hospital mortality. During the first 5 months of 2021, there was an increase in CVT hospitalization volume and increase in CVT-related mortality, partially attributable to VITT

    Circulating microRNAs in sera correlate with soluble biomarkers of immune activation but do not predict mortality in ART treated individuals with HIV-1 infection: A case control study

    Introduction: The use of anti-retroviral therapy (ART) has dramatically reduced HIV-1 associated morbidity and mortality. However, HIV-1 infected individuals have increased rates of morbidity and mortality compared to the non-HIV-1 infected population and this appears to be related to end-organ diseases collectively referred to as Serious Non-AIDS Events (SNAEs). Circulating miRNAs are reported as promising biomarkers for a number of human disease conditions including those that constitute SNAEs. Our study sought to investigate the potential of selected miRNAs in predicting mortality in HIV-1 infected ART treated individuals. Materials and Methods: A set of miRNAs was chosen based on published associations with human disease conditions that constitute SNAEs. This case: control study compared 126 cases (individuals who died whilst on therapy), and 247 matched controls (individuals who remained alive). Cases and controls were ART treated participants of two pivotal HIV-1 trials. The relative abundance of each miRNA in serum was measured, by RTqPCR. Associations with mortality (all-cause, cardiovascular and malignancy) were assessed by logistic regression analysis. Correlations between miRNAs and CD4+ T cell count, hs-CRP, IL-6 and D-dimer were also assessed. Results: None of the selected miRNAs was associated with all-cause, cardiovascular or malignancy mortality. The levels of three miRNAs (miRs -21, -122 and -200a) correlated with IL-6 while miR-21 also correlated with D-dimer. Additionally, the abundance of miRs -31, -150 and -223, correlated with baseline CD4+ T cell count while the same three miRNAs plus miR- 145 correlated with nadir CD4+ T cell count. Discussion: No associations with mortality were found with any circulating miRNA studied. These results cast doubt onto the effectiveness of circulating miRNA as early predictors of mortality or the major underlying diseases that contribute to mortality in participants treated for HIV-1 infection

    Family businesses from emerging markets and choice of entry mode abroad: insights from Indian firms

    Internationalization of family businesses (FBs) is an interesting topic that has received extensive attention in the literature during the last decades. Prior studies emphasized the conservative attitude toward risk of FBs. However, studies addressing international decisions of emerging-market FBs (EMFBs) are still scarce. We investigate whether home and host countries matter when EMFBs choose the entry mode abroad. By doing so, we discern whether they follow the same behavioral pattern as developed-country multinational enterprises (MNEs) or they show a distinctive strategic behavior. Drawing on a sample of 298 foreign market entries carried out by Indian MNEs, our results show that Indian FBs prefer acquisitions instead of greenfield investments. Moreover, host country factors matter, since outward foreign direct investment (OFDI) of Indian FBs in developed markets is associated with a preference for acquisitions, whereas OFDI in developing countries is associated with greenfield investments

    Ristola M. on työryhmien DAD Study Grp ; Royal Free Hosp Clin Cohort ; INSIGHT Study Grp ; SMART Study Grp ; ESPRIT Study Grp jäsen.Background Chronic kidney disease (CKD) is a major health issue for HIV-positive individuals, associated with increased morbidity and mortality. Development and implementation of a risk score model for CKD would allow comparison of the risks and benefits of adding potentially nephrotoxic antiretrovirals to a treatment regimen and would identify those at greatest risk of CKD. The aims of this study were to develop a simple, externally validated, and widely applicable long-term risk score model for CKD in HIV-positive individuals that can guide decision making in clinical practice. Methods and Findings A total of 17,954 HIV-positive individuals from the Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) study with >= 3 estimated glomerular filtration rate (eGFR) values after 1 January 2004 were included. Baseline was defined as the first eGFR > 60 ml/min/1.73 m2 after 1 January 2004; individuals with exposure to tenofovir, atazanavir, atazanavir/ritonavir, lopinavir/ritonavir, other boosted protease inhibitors before baseline were excluded. CKD was defined as confirmed (>3 mo apart) eGFR In the D:A:D study, 641 individuals developed CKD during 103,185 person-years of follow-up (PYFU; incidence 6.2/1,000 PYFU, 95% CI 5.7-6.7; median follow-up 6.1 y, range 0.3-9.1 y). Older age, intravenous drug use, hepatitis C coinfection, lower baseline eGFR, female gender, lower CD4 count nadir, hypertension, diabetes, and cardiovascular disease (CVD) predicted CKD. The adjusted incidence rate ratios of these nine categorical variables were scaled and summed to create the risk score. The median risk score at baseline was -2 (interquartile range -4 to 2). There was a 1: 393 chance of developing CKD in the next 5 y in the low risk group (risk score = 5, 505 events), respectively. Number needed to harm (NNTH) at 5 y when starting unboosted atazanavir or lopinavir/ritonavir among those with a low risk score was 1,702 (95% CI 1,166-3,367); NNTH was 202 (95% CI 159-278) and 21 (95% CI 19-23), respectively, for those with a medium and high risk score. NNTH was 739 (95% CI 506-1462), 88 (95% CI 69-121), and 9 (95% CI 8-10) for those with a low, medium, and high risk score, respectively, starting tenofovir, atazanavir/ritonavir, or another boosted protease inhibitor. The Royal Free Hospital Clinic Cohort included 2,548 individuals, of whom 94 individuals developed CKD (3.7%) during 18,376 PYFU (median follow-up 7.4 y, range 0.3-12.7 y). Of 2,013 individuals included from the SMART/ESPRIT control arms, 32 individuals developed CKD (1.6%) during 8,452 PYFU (median follow-up 4.1 y, range 0.6-8.1 y). External validation showed that the risk score predicted well in these cohorts. Limitations of this study included limited data on race and no information on proteinuria. Conclusions Both traditional and HIV-related risk factors were predictive of CKD. These factors were used to develop a risk score for CKD in HIV infection, externally validated, that has direct clinical relevance for patients and clinicians to weigh the benefits of certain antiretrovirals against the risk of CKD and to identify those at greatest risk of CKD.Peer reviewe
