Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Search for a Light Charged Higgs Boson Decaying to a W Boson and a CP-Odd Higgs Boson in Final States with eμμ or μμμ in Proton-Proton Collisions at √s=13 TeV

A search for a light charged Higgs boson (H+) decaying to a W boson and a CP-odd Higgs boson (A) in final states with eμμ or μμμ is performed using data from pp collisions at √s=13  TeV, recorded by the CMS detector at the LHC and corresponding to an integrated luminosity of 35.9  fb−1. In this search, it is assumed that the H+ boson is produced in decays of top quarks, and the A boson decays to two oppositely charged muons. The presence of signals for H+ boson masses between 100 and 160 GeV and A boson masses between 15 and 75 GeV is investigated. No evidence for the production of the H+ boson is found. Upper limits at 95% confidence level are obtained on the combined branching fraction for the decay chain, t→bH+→bW+A→bW+μ+μ−, of 1.9×10−6 to 8.6×10−6, depending on the masses of the H+ and A bosons. These are the first limits for these decay modes of the H+ and A bosons.Peer reviewe

El uso de la música en el tránsito del Reino a la República

El presente trabajo destaca cómo la música generada durante el proceso de emancipación tuvo su origen en un corpus sonoro tradicional que empieza a ser perseguido durante la segunda mitad del siglo XVIII debido a las nuevas formas de pensamiento de los borbones; la manera cómo este corpus con su carácter discordante se tornó propicio para injertarse en las letras a favor y en contra del movimiento de insurrección iniciado en 1810; y, finalmente, cómo algunos de sus versos contenían el germen del antiespañolismo que posteriormente sería utilizado por el naciente Estado mexicano como medio para generar identidad entre sus habitante

Determinación toxicológica de Cocaína, Marihuana y sus metabolitos en escolares de Educación Secundaria en Lima-Perú

Percentage of Drug abuse in Peruvian population is being determined only with inquiries and no toxiccological analysis is done. For the present study, 55 National High Schools from Lima, Perú, were selected considering those with high student population. The students age fluctuated between 15 and 19 years old, and 13 301 samples were analysed. The analysis results indicated that 15.9% of students had consumed cocaine; 9.9% marijuana; 0.7% benzodiazepine; 0.3% barbiturates and no one had consumed amphetamines. At the same time of sample collection, an inquiry, was performed results but the did not agree with the ones obtained from toxicological analysis. So, we concluded, that inquiries do not demonstrate the real percentage of drug abuse, since they are not answered with responsability by fue students, may be because of fear or shame to their drug-dependence situation.En el Perú, el porcentaje del consumo de drogas en la población viene siendo determinado mediante encuestas sin la realización de los análisis toxicológicos. Para el estudio se seleccionaron 55 colegios nacionales de educación secundaria del Departamento de Lima. Perú, considerando aquellos con gran cantidad de alumnos, con edades comprendidas entre los 15 y 19 años de edad, analizándose un total de 13 301 muestras. De los resultados de los análisis se concluye que el 15.9% de los alumnos consumían cocaína, el 9,9% marihuana, el 0,7% benzodiacepinas, el 0,3% barbitúricos y ninguno de ellos anfetaminas. Se realizó en forma paralela a la toma de muestra una encuesta, cuyo resultados no se aproximan a los obtenidos en los análisis toxicológicos, por lo que podemos afirmar que las encuestas no reflejan el porcentaje real del consumo de drogas

Search for new physics in dijet angular distributions using proton-proton collisions at root s=13 TeV and constraints on dark matter and other models

An Erratum to this article was published on 29 April 2022: https://doi.org/10.1140/epjc/s10052-022-10278-0search is presented for physics beyond the standard model, based on measurements of dijet angular distributions in proton-proton collisions at root s = 13 TeV. The data collected with the CMS detector at the LHC correspond to an integrated luminosity of 35.9 fb(-1). The observed distributions, corrected to particle level, are found to be in agreement with predictions from perturbative quantum chromodynamics that include electroweak corrections. Constraints are placed on models containing quark contact interactions, extra spatial dimensions, quantum black holes, or dark matter, using the detector-level distributions. In a benchmark model where only left-handed quarks participate, contact interactions are excluded at the 95% confidence level up to a scale of 12.8 or 17.5 TeV, for destructive or constructive interference, respectively. The most stringent lower limits to date are set on the ultraviolet cutoff in the Arkani-Hamed-Dimopoulos-Dvali model of extra dimensions. In the Giudice-Rattazzi-Wells convention, the cutoff scale is excluded up to 10.1 TeV. The production of quantum black holes is excluded for masses below 5.9 and 8.2 TeV, depending on the model. For the first time, lower limits between 2.0 and 4.6 TeV are set on the mass of a dark matter mediator for (axial-)vector mediators, for the universal quark coupling g(q) = 1.0.Peer reviewe
