Genetics, sex and the use of platelet-rich plasma influence the development of arthrofibrosis after anterior cruciate ligament reconstruction.

Purpose: To identify genes and patient factors that are related to the development of arthrofibrosis in patients after anterior cruciate ligament (ACL) reconstruction and to develop a prognostic model.

Methods: The study included patients diagnosed with ACL injury who underwent ACL reconstruction. Patients were enroled consecutively and divided into non-fibrotic (controls) and fibrotic (cases) groups until a balanced sample of matched case-control was achieved.

Prediction of the structure and mechanical properties of polycaprolactone-silica nanocomposites and the interphase region by molecular dynamics simulations: the effect of PEGylation.

Polymer/silica (PS) nanocomposites are, among numerous combinations of inorganic/organic nanocomposites, one of the most important materials reported in the literature and have been employed in a wide variety of applications. Due to this great interest in the scientific and industry community, knowledge about their physiochemistry allows for a better understanding of their development and improvement. One area of interest found in biopolymers is silica, where silica nanoparticles can be used to increase their mechanical properties and give them higher opportunities to replace synthetic plastics.

Incidence, Clinical Characteristics, Risk Factors and Outcomes of Acute Coronary Syndrome in Patients With COVID-19: Results of the UMC-19-S10.

Background: There is a lack of knowledge about the real incidence of acute coronary syndrome (ACS) in patients with COVID-19, their clinical characteristics, and their prognoses.

Objective: We investigated the incidence, clinical characteristics, risk factors, and outcomes of ACS in patients with COVID-19 in the emergency department.

Methods: We retrospectively reviewed all COVID-19 patients diagnosed with ACS in 62 Spanish emergency departments between March and April 2020 (the first wave of COVID-19).

The impact of Ibero-American science on global bioethical thinking.

The bioethics research conducted in Ibero-American countries has been very much restricted to its own realm. The aim of this study was to perform a bibliometric evaluation of bioethics papers by authors affiliated with Ibero-American institutions, and to determine how their work influences global bioethics literature. We performed a literature search in the Web of Science Core Collection (WoS CC) and Scopus.
