Comunicar para fortalecer la Universidad en pandemia

La pandemia por Covid-19 y el aislamiento social, preventivo y obligatorio, dispuesto a raíz de ella, ocasionó un escenario sin precedentes. En ese contexto de confinamiento, las comunicaciones a través de los medios sociales adoptaron un rol central aún mayor al que tenían, sobre todo en instituciones que requerían sostener el vínculo con sus stakeholders. El caso de la Universidad Nacional de Lomas de Zamora no fue la excepción, y por eso debió apelar a distintas estrategias comunicacionales para sostener lazos identitarios y de pertenencia con su comunidad en tiempos de incertidumbre como los vividos en el país durante 2020.

Efficacy of a Nasal Spray Containing Iota-Carrageenan in the Postexposure Prophylaxis of COVID-19 in Hospital Personnel Dedicated to Patients Care with COVID-19 Disease.

BACKGROUND: Iota-Carrageenan (I-C) is a sulfate polysaccharide synthesized by red algae, with demonstrated antiviral activity and clinical efficacy as nasal spray in the treatment of common cold. In vitro, I-C inhibits SARS-CoV-2 infection in cell culture. RESEARCH QUESTION: Can a nasal spray with Iota-Carrageenan be useful in the prophylaxis of COVID-19 in health care workers managing patients with COVID-19 disease? STUDY DESIGN AND METHODS: This is a pilot pragmatic multicenter, randomized, double-blind, placebo-controlled study assessing the use of a nasal spray containing I-C in the prophylaxis of COVID-19 in hospital personnel dedicated to care of COVID-19 patients. Clinically healthy physicians, nurses, kinesiologists and other health care providers managing patients hospitalized for COVID-19 were assigned in a 1:1 ratio to receive four daily doses of I-C spray or placebo for 21 days. The primary end point was clinical COVID-19, as confirmed by reverse transcriptase polymerase chain reaction testing, over a period of 21 days. The trial is registered at ClinicalTrials.gov (NCT04521322). RESULTS: A total of 394 individuals were randomly assigned to receive I-C or placebo. Both treatment groups had similar baseline characteristics. The incidence of COVID-19 differs significantly between subjects receiving the nasal spray with I-C (2 of 196 [1.0%]) and those receiving placebo (10 of 198 [5.0%]). Relative risk reduction: 79.8% (95% CI 5.3 to 95.4; p=0.03). Absolute risk reduction: 4% (95% CI 0.6 to 7.4). INTERPRETATION: In this pilot study a nasal spray with I-C showed significant efficacy in preventing COVID-19 in health care workers managing patients with COVID-19 disease. CLINICAL TRIALS REGISTRATION: NCT04521322.
