Ajuste psicológico en cuidadores familiares de adolescentes: un análisis longitudinal durante el confinamiento por la COVID-19 en España
2021
Debido al confinamiento por la COVID-19, las familias españolas tuvieron que adaptarse a nuevas situaciones y rutinas. El objetivo de esta investigación ha sido conocer qué variables explicaban el ajuste psicológico de cuidadores familiares de adolescentes ante la COVID-19, mediante un estudio longitudinal (evaluando primero a las 2-3 semanas del inicio del estado de alarma y después tras 8 semanas de su instauración en España). Participaron 32 progenitores de adolescentes. Tras aceptar participar, se evaluó: clima familiar, satisfacción vital, regulación emocional, resiliencia y psicopatología. Se realizaron modelos de análisis comparativo cualitativo de conjuntos difusos (fsQCA). Nuestros…

COVID-19 Vaccination in Pregnancy, Paediatrics, Immunocompromised Patients, and Persons with History of Allergy or Prior SARS-CoV-2 Infection: Overvi…
2021
To date, four vaccines have been authorised for emergency use and under conditional approval by the European Medicines Agency to prevent COVID-19: Comirnaty, COVID-19 Vaccine Janssen, Spikevax (previously COVID-19 Vaccine Moderna) and Vaxzevria (previously COVID-19 Vaccine AstraZeneca). Although the benefit–risk profile of these vaccines was proven to be largely favourable in the general population, evidence in special cohorts initially excluded from the pivotal trials, such as pregnant and breastfeeding women, children/adolescents, immunocompromised people and persons with a history of allergy or previous SARS-CoV-2 infection, is still limited. In this narrative review, we critically overv…

AbstractThe COVID-19 pandemic has surprised the entire population. The world has had to face an unprecedented pandemic. Only, Spanish flu had similar disastrous consequences. As a result, drastic measures (lockdown) have been adopted worldwide. Healthcare service has been overwhelmed by the extraordinary influx of patients, often requiring high intensity of care. Mortality has been associated with severe comorbidities, including chronic diseases. Patients with frailty were, therefore, the victim of the SARS-COV-2 infection. Allergy and asthma are the most prevalent chronic disorders in children and adolescents, so they need careful attention and, if necessary, an adaptation of their regular…
Affinity Sensors for the Diagnosis of COVID-19
2021
The coronavirus disease 2019 (COVID-19) outbreak caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was proclaimed a global pandemic in March 2020. Reducing the dissemination rate, in particular by tracking the infected people and their contacts, is the main instrument against infection spreading. Therefore, the creation and implementation of fast, reliable and responsive methods suitable for the diagnosis of COVID-19 are required. These needs can be fulfilled using affinity sensors, which differ in applied detection methods and markers that are generating analytical signals. Recently, nucleic acid hybridization, antigen-antibody interaction, and change of reactive oxyge…
Application of C1-Esterase Inhibitor During Reperfusion of Ischemic Myocardium
2001
Background—Complement activation during reperfusion of ischemic myocardium augments myocardial injury, and complement inhibition with C1-esterase inhibitor (C1-INH) at the time of reperfusion exerts marked cardioprotective effects in experimental studies. Application of C1-INH in newborns, however, was recently reported to have dangerous and even lethal side effects. This study addresses the essential role of dosage in studies using C1-INH.Methods and Results—Cardioprotection by C1-INH was examined in a pig model with 60 minutes of coronary occlusion followed by 120 minutes of reperfusion. C1-INH was administered intravenously 5 to 10 minutes before coronary reperfusion without heparin at a…
Single-cell RNA Expression of SARS-CoV-2 Cell Entry Factors in Human Endometrium during Preconception
2020
AbstractWe investigated potential SARS-CoV-2 tropism in human endometrium by single-cell RNA-sequencing of viral entry-associated genes in healthy women. Percentages of endometrial cells expressing ACE2, TMPRSS2, CTSB, or CTSL were <2%, 12%, 80%, and 80%, respectively, with 0.7% of cells expressing all four genes. Our findings imply low efficiency of SARS-CoV-2 infection in the endometrium before embryo implantation, providing information to assess preconception risk in asymptomatic carriers.

Focus on clinical practice: angiotensin-converting enzyme 2 and corona virus disease 2019: pathophysiology and clinical implications.
2020
: ACE2 receptor has a broad expression pattern in the cellular membrane and provides a protective action against the development of cardiovascular diseases. Recently, this enzyme has become of extreme interest during the pandemic infection of COVID-19 (coronavirus disease 2019). This virus invades alveolar epithelium and cardiomyocytes using ACE2 as a transmembrane receptor. ACE2 is a counter-regulatory peptide that degrades Ang II into Ang 1-7, thereby attenuating the biological effects of the AT1 receptor. The binding between the spike protein of COVID-19 and the enzyme is crucial for the virus to enter the target cells, but whether an increase in ACE2 activity could facilitate the infect…
Cardiopatías y enfermedades periodontales: ¿existen evidencias de asociación?
2005
Las enfermedades cardiovasculares representan una de las principales causas de muerte en las sociedades desarrolladas. Estas enfermedades no sólo son importantes por la mortalidad que generan, sino por la gran cantidad de individuos afectados y en tratamiento que han de soportar los sistemas de salud de los distintos países. De ahí que la detección precoz de los factores de riesgo conducentes a desencadenar estas enfermedades haya sido vista como el mecanismo más eficaz para prevenirlas. En los últimos tiempos se viene relacionando de una manera más o menos directa a la patología periodontal con el padecimiento de enfermedades cardiovasculares. Este hecho podría tener una gran relevancia cl…
