Hydroxychloroquine and Tocilizumab in the Treatment of COVID-19: A Longitudinal Observational Study

Objetivos El objetivo del trabajo fue evaluar el empleo de la hidroxicloroquina y el tocilizumab al comienzo de la pandemia, así como describir el perfil de los pacientes que recibieron estos tratamientos. Métodos Se analizaron las historias clínicas de 403 pacientes que ingresaron por COVID-19 desde el 1 de marzo hasta el 15 de abril de 2020 en el Hospital Universitario San Cecilio (Granada, España). Los datos recogidos incluían sexo, edad, días hospitalizados, patologías y/o tratamientos previos, posibles desenlaces y fármacos administrados en el centro. Para estimar las posibles asociaciones entre las variables definidas se utilizaron los parámetros estadísticos T de Student y χ² de Pearson. Resultados Los pacientes, con una edad media de 66 años (desviación estándar = 15,38), estuvieron hospitalizados un promedio de 15 días (desviación estándar = 12,89). La tasa de ingreso en UCI fue del 9,93 % y la de fallecimientos ascendió al 17,37 % del total de individuos. Durante la primera onda epidémica se administró la hidroxicloroquina a la mayoría de pacientes ingresados, mientras que el tocilizumab se restringió a los cuadros clínicos más graves. Conclusiones Los resultados obtenidos en este trabajo mostraron dos tendencias distintas en el uso de los fármacos estudiados. El tocilizumab se administró a un número muy reducido de pacientes, principalmente aquellos de mayor estancia o con complicaciones. La hidroxicloroquina se empleó independientemente de las características iniciales de los pacientes, con especial relevancia en aquellos que presentaban comorbilidades o estaban polimedicados.Objectives The objective of this study is to evaluate the use of hydroxychloroquine and tocilizumab at the beginning of the COVID-19 pandemic and to describe the profile of patients who received these treatments. Method The medical records of 403 patients admitted for COVID-19 from March 1 to April 15, 2020 at the San Cecilio University Hospital (Granada, Spain) were analyzed. The data collected included sex, age, days hospitalized, previous pathologies and/or treatments, possible outcomes and drugs administered at the hospital. Student’s t-test and Pearson’s chi-square tests were used as statistical parameters to estimate the possible associations between the defined variables. Results Patients with a mean age of 66 years (standard deviation = 15.38), were hospitalized for an average of 15 days (standard deviation = 12.89). The ICU admission rate was 9.93 %, and the death rate added up to 17.37 % of the total number of patients. During the first wave of the pandemic, hydroxychloroquine was administered to the majority of hospitalized patients, while tocilizumab was restricted to the more severe cases. Conclusions The results showed two distinct trends in the use of the drugs studied. Tocilizumab was administered to a small number of patients, mainly those with longer length of stay or with complications. Hydroxychloroquine was administered independently of the initial characteristics of patients, especially those who presented comorbidities or took multiple medications

Design and construction of a proportional gas flow meter with application in Mössbauer spectroscopy

The design, construction and operation parameters of a gas flow proportional counter are presented in order to implement the integral conversion electron mössbauer spectroscopy technique (ICEMS). The detector works with the support of a multi-channel detection system and a source of highenergy radiation of 57Co. A constant gas flow of a mixture of 5% CH4 in He was used as a multiplier gas, which increased the signal intensity, and protected the sample´s surface of electric shocks. An internal filter for low energy X-rays was considered during the design to achieve a lower background noise and optimize the volume of gas consumed. With this built-in ICEMS detector it is feasible to characterize efficiently the magnetic properties and oxidation states (hyperfine interactions) of both bulk materials and thin films. The calibration of the device was performed by using an iron sample synthesized by powder metallurgy. It was successfully identified the presence of a distinctive sextet of the α-Fe phase with a hyperfine field of 330 kOe and an isomer shift of 0.312 mm / s. The great usefulness of the equipment was verified by solving the magnetic hyperfine interactions of the Mössbauer spectrum associated to a commercial stainless-steel washer.The design, construction and operation parameters of a gas flow proportional counter are presented in order to implement the integral conversion electron mössbauer spectroscopy technique (ICEMS).

GAPS-megacities: A new global platform for investigating persistent organic pollutants and chemicals of emerging concern in urban air

A pilot study was initiated in 2018 under the Global Atmospheric Passive Sampling (GAPS) Network named GAPS-Megacities. This study included 20 megacities/major cities across the globe with the goal of better understanding and comparing ambient air levels of persistent organic pollutants and other chemicals of emerging concern, to which humans residing in large cities are exposed. The first results from the initial period of sampling are reported for 19 cities for several classes of flame retardants (FRs) including organophosphate esters (OPEs), polybrominated diphenyl ethers (PBDEs), and halogenated flame retardants (HFRs) including new flame retardants (NFRs), tetrabromobisphenol A (TBBPA) and hexabromocyclododecane (HBCDD). The two cities, New York (USA) and London (UK) stood out with ∼3.5 to 30 times higher total FR concentrations as compared to other major cities, with total concentrations of OPEs of 15,100 and 14,100 pg/m3, respectively. Atmospheric concentrations of OPEs significantly dominated the FR profile at all sites, with total concentrations in air that were 2-5 orders of magnitude higher compared to other targeted chemical classes. A moderately strong and significant correlation (r = 0.625, p < 0.001) was observed for Gross Domestic Product index of the cities with total OPEs levels. Although large differences in FR levels were observed between some cities, when averaged across the five United Nations regions, the FR classes were more evenly distributed and varied by less than a factor of five. Results for Toronto, which is a "reference city" for this study, agreed well with a more in-depth investigation of the level of FRs over different seasons and across eight sites representing different urban source sectors (e.g. traffic, industrial, residential and background). Future sampling periods under this project will investigate trace metals and other contaminant classes, linkages to toxicology, non-targeted analysis, and eventually temporal trends. The study provides a unique urban platform for evaluating global exposome.Fil: Saini, Amandeep. Environment and Climate Change; CanadáFil: Harner, Tom.

A Functional Pipeline of Genome-Wide Association Data Leads to Midostaurin as a Repurposed Drug for Alzheimer’s Disease

Genome-wide association studies (GWAS) constitute a powerful tool to identify the different biochemical pathways associated with disease. This knowledge can be used to prioritize drugs targeting these routes, paving the road to clinical application. Here, we describe DAGGER (Drug Repositioning by Analysis of GWAS and Gene Expression in R), a straightforward pipeline to find currently approved drugs with repurposing potential. As a proof of concept, we analyzed a meta-GWAS of 1.6 × 107 single-nucleotide polymorphisms performed on Alzheimer’s disease (AD). Our pipeline uses the Genotype-Tissue Expression (GTEx) and Drug Gene Interaction (DGI) databases for a rational prioritization of 22 druggable targets. Next, we performed a two-stage in vivo functional assay. We used a C. elegans humanized model over-expressing the Aβ1-42 peptide. We assayed the five top-scoring candidate drugs, finding midostaurin, a multitarget protein kinase inhibitor, to be a protective drug. Next, 3xTg AD transgenic mice were used for a final evaluation of midostaurin’s effect. Behavioral testing after three weeks of 20 mg/kg intraperitoneal treatment revealed a significant improvement in behavior, including locomotion, anxiety-like behavior, and new-place recognition. Altogether, we consider that our pipeline might be a useful tool for drug repurposing in complex diseases.This work was mainly financed by Programa Operativo FEDER funds from the European Union through grant UMA20-FEDERJA-133.
