Clinical and demographic characteristics of patients dying from COVID-19 in Italy vs China.
2020
Abstract Coronavirus disease 2019 (COVID‐19), an infectious outbreak caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2),1 has now progressed to global pandemic.2 Besides the compelling need to understand the novel biological pathways underlying the virulence and pathogenicity of SARS‐CoV‐2 in humans to enable the development of appropriate interventions and therapies,3,4 the noticeable difference in mortality rates between Asian and European populations is one of the most significant issues demanding the attention of biologists, epidemiologists and clinicians around the world.

Correction to: The dysregulated innate immune response in severe COVID-19 pneumonia that could drive poorer outcome
2021
Although immune modulation is a promising therapeutic avenue in coronavirus disease 2019 (COVID-19), the most relevant targets remain to be found. COVID-19 has peculiar characteristics and outcomes, suggesting a unique immunopathogenesis.Thirty-six immunocompetent non-COVID-19 and 27 COVID-19 patients with severe pneumonia were prospectively enrolled in a single center, most requiring intensive care. Clinical and biological characteristics (including T cell phenotype and function and plasma concentrations of 30 cytokines) and outcomes were compared.At similar baseline respiratory severity, COVID-19 patients required mechanical ventilation for significantly longer than non-COVID-19 patients …
Treatment of COVID-19 with MSCs: how does it work?
2021
The infusion of coronavirus disease 2019 (COVID-19) patients with mesenchymal stem cells (MSCs) potentially improves clinical symptoms, but the underlying mechanism remains unclear. We conducted a randomized, single-blind, placebo-controlled (29 patients/group) phase II clinical trial to validate previous findings and explore the potential mechanisms. Patients treated with umbilical cord-derived MSCs exhibited a shorter hospital stay (P = 0.0198) and less time required for symptoms remission (P = 0.0194) than those who received placebo. Based on chest images, both severe and critical patients treated with MSCs showed improvement by day 7 (P = 0.0099) and day 21 (P = 0.0084). MSC-treated pat…
Hospitalizations for Stroke in France During the COVID-19 Pandemic Before, During, and After the National Lockdown.
2021
Background and Purpose: In France, the entire population was put under a total lockdown from March 17 to May 11, 2020 during the peak of the coronavirus disease 2019 (COVID-19) pandemic. Whether the lockdown had consequences on the management of medical emergencies such as stroke and transient ischemic attack (TIA) has yet to be fully evaluated. This article describes hospitalization rates for acute stroke in 2 French regions that experienced contrasting rates of COVID-19 infection, before, during, and after the nationwide lockdown (January to June 2020). Methods: All patients admitted for acute stroke/TIA into all public and private hospitals of the 2 study regions were included. Data wer…

Pediatric routine vaccinations in the COVID 19 lockdown period: the survey of the Italian Pediatric Society
2021
Abstract Background COVID-19 pandemic was responsible for disrupting routine immunization activities all over the world. Aim of the study was to investigate the reduced adherence to the national children vaccination schedule during the lockdown period in Italy. Materials and methods Through social channels, the Italian Pediatric Society conducted a survey among Italian families on children vaccination during lockdown period. Results In the study period, 1474 responders were collected. More than one third (34%) of them skipped the vaccine appointment as they were afraid of SARS-CoV-2-virus (44%), vaccination services postponed the appointment (42%) or was closed to public (13%). Discussion R…
1.5 vs 3 Tesla Magnetic Resonance Imaging
2021
ABSTRACT: The second part of this review deals with experiences in neuroradiological and pediatric examinations using modern magnetic resonance imaging systems with 1.5 T and 3 T, with special attention paid to experiences in pediatric cardiac imaging. In addition, whole-body examinations, which are widely used for diagnostic purposes in systemic diseases, are compared with respect to the image quality obtained in different body parts at both field strengths. A systematic overview of the technical differences at 1.5 T and 3 T has been presented in part 1 of this review, as well as several organ-based magnetic resonance imaging applications including musculoskeletal imaging, abdominal imagin…
Intraocular Pressure Telemetry for Managing Glaucoma during the COVID-19 Pandemic
2021
Purpose To evaluate in glaucoma patients the feasibility and use of remote monitoring of intraocular pressure (IOP) with an implanted telemetry sensor during the coronavirus disease 2019 (COVID-19) lockdown. Design Cross-sectional study. Participants Patients previously implanted with a telemetric IOP sensor (Eyemate; Implandata GmbH) were included. Methods Intraocular pressure measurements acquired by the patients during the lockdown were collected by physicians who were located remotely. A questionnaire was sent to 10 participating study centers to evaluate the clinical impact of remote monitoring of IOP via the IOP sensor system. Main Outcome Measures Number of patients who obtained home…
Clinical profile and predictors of in-hospital mortality among older patients hospitalised for COVID-19.
2020
Abstract Background the coronavirus disease 2019 (COVID-19) is characterized by poor outcomes and mortality, particularly in older patients. Methods post hoc analysis of the international, multicentre, ‘real-world’ HOPE COVID-19 registry. All patients aged ≥65 years hospitalised for COVID-19 were selected. Epidemiological, clinical, analytical and outcome data were obtained. A comparative study between two age subgroups, 65–74 and ≥75 years, was performed. The primary endpoint was all cause in-hospital mortality. Results about, 1,520 patients aged ≥65 years (60.3% male, median age of 76 [IQR 71–83] years) were included. Comorbidities such as hypertension (69.2%), dyslipidaemia (48.6%), card…
