Background rates of 41 adverse events of special interest for COVID-19 vaccines in 10 European healthcare databases - an ACCESS cohort study.

BACKGROUND: In May 2020, the ACCESS (The vACCine covid-19 monitoring readinESS) project was launched to prepare real-world monitoring of COVID-19 vaccines. Within this project, this study aimed to generate background incidence rates of 41 adverse events of special interest (AESI) to contextualize potential safety signals detected following administration of COVID-19 vaccines. METHODS: A dynamic cohort study was conducted using a distributed data network of 10 healthcare databases from 7 European countries (Italy, Spain, Denmark, The Netherlands, Germany, France and United Kingdom) over the period 2017 to 2020. A common protocol (EUPAS37273), common data model, and common analytics programs were applied for syntactic, semantic and analytical harmonization. Incidence rates (IR) for each AESI and each database were calculated by age and sex by dividing the number of incident cases by the total person-time at risk. Age-standardized rates were pooled using random effect models according to the provenance of the events. FINDINGS: A total number of 63,456,074 individuals were included in the study, contributing to 211.7 million person-years. A clear age pattern was observed for most AESIs, rates also varied by provenance of disease diagnosis (primary care, specialist care). Thrombosis with thrombocytopenia rates were extremely low ranging from 0.06 to 4.53/100,000 person-years for cerebral venous sinus thrombosis (CVST) with thrombocytopenia (TP) and mixed venous and arterial thrombosis with TP, respectively. INTERPRETATION: Given the nature of the AESIs and the setting (general practitioners or hospital-based databases or both), background rates from databases that show the highest level of completeness (primary care and specialist care) should be preferred, others can be used for sensitivity. The study was designed to ensure representativeness to the European population and generalizability of the background incidence rates. FUNDING: The project has received support from the European Medicines Agency under the Framework service contract nr EMA/2018/28/PE.

Relación entre la grasa corporal y la expresión de ira en personas que realizan ejercicio regularmente / Relacionamento entre gordura corporal e expressão de raiva em pessoas que se exercitam regularmente / Relationship between body fat mass and the expression of anger in people who practice exercise customarily

La actividad física proporciona beneficios, tanto a la población sana como enferma, pero también puede derivar en problemas psicológicos y emocionales como respuesta al estrés. Además, aquellos atletas con menor peso corporal presentan indicadores más elevados de depresión e ira. Se plantea determinar la relación de la grasa corporal sobre la expresión de ira y entender la relación entre distintos comportamientos psicológicos, en personas físicamente activas. 264 sujetos cumplimentaron el Inventario de Expresión de Ira Estado-Rasgo, versión 2, para el estudio sobre las características de la ira y sus efectos en la salud mental y física. Se tomaron medidas antropométricas (peso, talla, IMC, porcentaje de grasa corporal, masa libre de grasa). Se calcularon distintos percentiles en función del género y edad, clasificando a los participantes en tres grupos: percentil 55 de grasa corporal. Se analizaron distintos comportamientos en relación al STAXI-2 y a los distintos percentiles, pero sin encontrar diferencias significativas entre la ira y los tres grupos (AU)

Physical activity provides benefits, both to healthy as to ill population, but can also lead to psychological and emotional problems in response to stress. Furthermore, those athletes with lower body weight have higher indicators of depression and anger. We propose to relate body fat on the expression of anger and to understand the relationship between different psychological behaviors in physically active people. 264 subjects completed the Anger Expression Inventory State Trait version 2 (STAXI-2), which studies the characteristics of anger and its effects on mental and physical health. Anthropometric measurements (weight, height, BMI, percent body fat, fat-free mass) were taken. Various body fat percentiles, 55 were calculated according to gender and age, classifying participants into three percentile groups. Different behaviors were recorded in relation to STAXI-2 and percentiles, but with no significant differences between anger and those groups (AU)

Risk of ischemic stroke associated with non-steroidal anti-inflammatory drugs and paracetamol: a population-based case-control study.

OBJECTIVE: To assess the risk of non-fatal ischemic stroke associated with non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol. The effects of dose, duration of treatment, background cardiovascular (CV) risk and use of concomitant aspirin were studied. METHODS: We performed a population-based case-control study. Patients were considered exposed if they were on treatment within a 30-day window before the index date. We estimated adjusted odds ratios (ORs) and their 95% confidence intervals (CIs) using logistic regression. RESULTS: Two thousand eight hundred and eighty-eight cases and 20 000 controls were included. No increased risk was observed with traditional NSAIDs as a group (OR = 1.03; 95% CI, 0.90-1.19), but results varied across individual agents and conditions of use. An increased risk was found with diclofenac (OR = 1.53; 95% CI, 1.19-1.97), in particular when used at high doses (OR = 1.62; 1.06-2.46), over long-term periods (> 365 days; OR = 2.39; 1.52-3.76) and in patients with a high background CV risk (OR = 1.78; 1.23-2.58), as well as with aceclofenac when used at high doses (OR = 1.67; 1.05-2.67), in long-term treatments (OR = 2.00; 1.14-3.53) and in patients with CV risk factors (OR = 2.33; 1.40-3.87). No association was found with ibuprofen (OR = 0.94; 0.76-1.17) or naproxen (OR = 0.68; 0.36-1.29). The concomitant use of aspirin did not show a significant effect modification. Paracetamol did not increase the risk overall (OR = 0.97; 0.85-1.10) or in patients at high CV risk (OR = 0.94; 0.78-1.14). CONCLUSIONS: Diclofenac and aceclofenac increase the risk of ischemic stroke while ibuprofen and naproxen do not. Dose, duration and baseline CV risk, but not aspirin use, appear to modulate the risk. Paracetamol does not increase the risk, even in patients with a high background CV risk.

Effect of laser remelting on the tribological performance of thermal barrier coatings.

Gas turbine's efficiency improves as operating temperature is increased. For this reason, metallic components used in turbine engines, for propulsion and power generation, are protected by thermal barrier coatings (TBC). Laser glazing has been used to enhance the oxidation and corrosion resistance of thermally sprayed TBC, but there is no information about the effect of this treatment on the tribological performance. ZrO2(CaO) top coat and NiAIMo bond coating were flame sprayed onto an AlSI 1045 carbon steel. The top coat was laser remelted and a densified ceramic layer was induced in the top surface of the ceramic coating. Both, the as sprayed and the laser remelted top coatings, were formed by cubic ZrO2 with some tetragonal precipitates. The grain size was reduced by the laser treatment. The mechanical properties and the local wear rate were evaluated by depth sensing indentation and scratch tests respectively. The nanoscale wear behaviour was always improved by the laser treatment.

Evaluation of inappropriate prescribing according to Beers criteria in cardiology and respiratory medicine departments

Objetivo. Conocer la incidencia de prescripciones potencialmente inapropiadas (PPI) de los pacientes mayores de 65 años ingresados en las unidades de neumología y cardiología, así como los fármacos principalmente implicados y su severidad clínica. Métodos. Estudio observacional, prospectivo, de 6 meses de duración. Se revisaron los tratamientos de los pacientes mayores de 65 años ingresados en estas unidades. Se consideraron como PPI las incluidas en la lista de Beers de 2003. Se recogió la unidad clínica, edad, sexo, fármaco inapropiado, dosis y vía de administración. Se calculó la incidencia de PPI (número de PPI/número de pacientes) global y en función la unidad clínica, así como según el sexo, fármaco implicado y severidad clínica. Resultados. Se recogieron datos de 385 pacientes (190 en cardiología y 195 en neumología). Se encontraron 111 PPI (0,29 PPI/paciente). Teniendo en cuenta la unidad de origen, se encontraron 53 PPI en cardiología (0,28 PPI/paciente) y 58 PPI en neumología (0,30 PPI/paciente). El 66,6% (n=74) de las PPI ocurrieron en hombres y el 33,4% (n=37) en mujeres. Los principales fármacos implicados fueron amiodarona (24,3%), digoxina (19,8%), doxazosina (17,1%) y diazepam (16,2%). El 68,5% de las PPI encontradas fueron de severidad alta según los criterios de Beers. Conclusión. La prescripción de medicamentos inapropiados en ancianos es elevada. Esto es importante ya que son una de las causas de aparición de reacciones adversas a medicamentos, las cuales provocan a su vez una parte importante de los ingresos hospitalarios. La inclusión de alertas en el programa de prescripción asistida y la difusión de boletines informativos al respecto en el personal implicado mejoraría la calidad de la asistencia sanitaria y minimizaría los problemas relacionados con la medicación(AU)

Objective. To determine the incidence of potentially inappropriate prescriptions (PPI) for patients older than 65 years admitted to the cardiology and respiratory medicine units, as well as the main drugs involved and their clinical severity. Methods. A prospective, observational study was carried out over a 6 month period. We reviewed the treatment of patients over 65 years old admitted to these units. PPI is considered as those included in the Beers criteria 2003. We recorded clinical unit, age, sex, inappropriate drug, dosage and route of administration. We calculated the overall incidence of PPI (number of PPI/number of patients) and according to the clinical unit, sex, drug involved, and clinical severity. Results. Data were collected from 385 patients (190 in cardiology and 195 respiratory medicine unit). We found 111 PPI (0.29 PPI/patient). If we take into account the clinical unit, there were 53 PPI in cardiology (0.28 PPI/patient) and 58 PPI in respiratory medicine (0.30 PPI/patient). Two-thirds (66.6%, n=74) of the PPI occurred in men and 33.4% (n=37) in women. The main drugs involved were amiodarone (24.3%), digoxin (19.8%), doxazosin (17.1%) and diazepam (16.2%). According to the Beers criteria, 68.5% of those were high severity PPI. Conclusion. The prescription of inappropriate medications in the elderly is high. This is important because they are a cause of adverse reactions, which leads to a significant proportion of hospital admissions. The inclusion of warnings in the program of assisted prescribing and distributing of newsletters about these to the personnel involved, improves the quality of health care and minimises medication-related problems(AU)

Utilización terapéutica de los anticuerpos monoclonales / Therapeutic use of monoclonal antibodies

La utilización de terapias basadas en anticuerpos monoclonales ha supuesto un gran avance en la práctica clínica. Tienen un ámbito de utilización muy diverso, incluyendo aplicaciones diagnósticas y terapéuticas principalmente. En cuanto a su uso como tratamiento, las áreas más beneficiadas con su descubrimiento han sido la oncología y las enfermedades del sistema inmune.Se trata de un área en continuo crecimiento, tanto por la aparición de nuevos fármacos, como por la ampliación de indicaciones de los ya existentes. Esta revisión resume las características farmacológicas más importantes de los anticuerpos monoclonales comercializados en nuestro país. Se centra principalmente en la utilidad terapeútica, dosificación, eventos adversos de gran relevancia clínica y consideraciones importantes para su correcta administración. También se realiza un breve apunte de las indicaciones de los anticuerpos monoclonales autorizados por la agencia europea del medicamento (EMEA) y que se encuentran en distintas fases del proceso de comercialización(AU)

The utilization of therapies based on monoclonal antibodies has supposed a great advance in the clinical practice. They have a diverse field of use, including diagnostic and therapeutic applications. As treatment, the most benefited has been the oncology and immune system diseases.This is an area in continuous growth, so much for the appearance of new medicaments, since for the extension of indications of the already existing ones. This review summarizes the most important pharmacological characteristics of the monoclonal antibodies commercialized in our country. It centres principally on the authorized indications, dosing, adverse events of great clinical relevancy and important considerations for his correct administration. Also there is realized a brief note of the indications of the monoclonal antibodies authorized by the European agency of the medicine (EMEA) and that are in different phases of the process of commercialization(AU)

Improving thermal barrier coatings by laser remelting.

Thermal barrier coatings are extensively used to protect metallic components in applications where the operating conditions include aggressive environment at high temperatures. These coatings are usually processed by thermal spraying techniques and the resulting microstructure includes thin and large splats, associated with the deposition of individual droplets, with porosity between splats. This porosity reduces the oxidation and corrosion resistance favouring the entrance of aggressive species during service. To overcome this limitation, the top coat could be modified by laser glazing reducing surface roughness and sealing open porosity. ZrO2(Y2O3) top coat and NiCrAlY bond coating were air plasma sprayed onto an Inconel 600 Ni base alloy. The top coat was laser remelted and a densified ceramic layer was induced in the top surface of the ceramic coating. This layer inhibited the ingress of aggressive species and delayed bond coat oxidation.

Latex allergy: low prevalence of immunoglobulin E to highly purified proteins Hev b 2 and Hev b 13.

BACKGROUND: Hevea brasiliensis (Hev b) 2 and Hev b 13 have recently been identified as major latex allergens by detecting specific IgE antibodies in >50% of sera from Hev b latex-allergic individuals. OBJECTIVE: We assessed the prevalence rates for sensitization to extensively purified latex allergens in patients from three diverse geographical areas. METHODS: Native Hev b 2, Hev b 5, Hev b 6.01 and Hev b 13 were purified by non-denaturating chromatography and were used in ELISAs to assess sera from 215 latex-allergic patients and 172 atopic non-sensitized controls from Finland, Spain and the United States to detect allergen-specific IgE antibodies. RESULTS: Unexpectedly, even highly purified Hev b 13 contained epitope(s) to which Hev b 6-specific human IgE antibodies bound effectively. Further purification, however, reduced the prevalence of IgE antibody reactivity to low levels: 15%, 5% and 11% for Hev b 2, and 18%, 30% and 27% for Hev b 13 among latex-allergic Finnish, Spanish and American patients, respectively. Interestingly, Finnish patients had a lower prevalence of Hev b 5-specific IgE antibody (28%) as compared with Spanish (49%) and American (71%) patients. The prevalence of Hev b 6.01-specific IgE reactivity was uniformly >50% in all three populations. CONCLUSION: Neither Hev b 2 nor Hev b 13 appear to be major latex allergens when evaluated in serological assays using highly purified allergens. The reason(s) for the observed differences in published sensitization rates in various geographic regions requires further study. The purity of the allergen preparations has a marked impact on the accuracy of latex-specific IgE antibody detection in epidemiological studies and in the serological diagnosis of latex allergy.

Assessment of a new brand of determinants for skin testing in a large group of patients with suspected beta-lactam allergy.

BACKGROUND: Skin testing with major and minor determinants of benzylpenicillin is recommended standard practice for the evaluation of patients with immediate hypersensitivity reactions to beta-lactams. However, commercial reagents for this purpose were recently dropped from the European market. OBJECTIVE: In the present study, we assessed a new brand of reagents for use in skin testing in patients with suspected penicillin allergy. METHODS: Prick tests and intradermal tests were performed with benzylpenicilloyl polylysine (PPL) and minor determinant mixture (MDM). Penicillin G, amoxicillin, and the culprit beta-lactam were also tested. If skin tests were negative, a single-blind oral challenge test was performed with the culprit active principle or penicillin. If both skin tests and challenge tests were negative, the same procedure was repeated between 2 and 4 weeks later. RESULTS: A total of 636 patients were assessed. The allergy study was positive in 69 patients. Skin tests with PPL were positive in 30 patients (46.8%) and with MDM in 28 (43.7%). Sixteen patients displayed a positive reaction to both PPL and MDM (25%), while 42 patients (65.6%) had a positive reaction to either PPL or MDM alone. Thirty-two patients had positive skin test reactions to penicillin G or another p-lactam antibiotic. Five patients in whom a negative result was obtained in skin tests had a positive reaction to oral challenge. CONCLUSIONS: Our results indicate that a new brand of determinants that is commercially available in Europe is a reliable and useful tool for the diagnosis of beta-lactam allergy. The new reagents are a safe alternative to the previously available brand.
