Aerosol delivery systems for treating obstructive airway diseases during the SARS-CoV-2 pandemic.
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes CoronaVirus Disease 2019 (COVID-19), has resulted in a worldwide pandemic and currently represents a major public health crisis. It has caused outbreaks of illness through person-to-person transmission of the virus mainly via close contacts, and droplets produced by an infected person's cough or sneeze. Aerosolised inhaled therapy is the mainstay for treating obstructive airway diseases at home and in healthcare settings, but there is heightened particular concern about the potential risk for transmission of SARS-CoV-2 in the form of aerosolised respiratory droplets during the nebulised treatment of patients with COVID-19. ⋯ Furthermore, some patients may be unable to adequately use their new device and may not benefit fully from the switch to treatment via hand-held inhalers. Thus, there is no compelling reason to alter aerosol delivery devices for patients with established nebuliser-based regimens. The purpose of this paper is to discuss the current evidence and understanding of the use of aerosolised inhaled therapies during the SARS-CoV-2 pandemic and to provide some guidance on the measures to be taken to minimise the risk of transmitting infection, if any, during aerosol therapies.

Growing reports since the beginning of the pandemic and till date describe increased rates of cardiac complications (CC) in the active phase of coronavirus disease 2019 (COVID-19). CC commonly observed include myocarditis/myocardial injury, arrhythmias and heart failure, with an incidence reaching about a quarter of hospitalized patients in some reports. The increased incidence of CC raise questions about the possible heightened susceptibility of patients with cardiac disease to develop severe COVID-19, and whether the virus itself is involved in the pathogenesis of CC. ⋯ The induced CC seem to dramatically impact the prognosis of COVID-19, with some studies suggesting over 50% mortality rates with myocardial damage, up from ~ 5% overall mortality of COVID-19 alone. Thus, it is particularly important to investigate the relation between COVID-19 and heart disease, given the major effect on morbidity and mortality, aiming at early detection and improving patient care and outcomes. In this article, we review the growing body of published data on the topic to provide the reader with a comprehensive and robust description of the available evidence and its implication for clinical practice.

Multicenter Study
Intensive cardiac care unit admission trends during the COVID-19 outbreak in Italy: a multi-center study.
A significant decline in the admission to intensive cardiac care unit (ICCU) has been noted in Italy during the COVID-19 outbreak. Previous studies have provided data on clinical features and outcome of these patients, but information is still incomplete. In this multicenter study conducted in six ICCUs, we enrolled consecutive adult patients admitted to ICCU in three specific time intervals: from February 8 to March 9, 2020 [before national lockdown (pre-LD)], from March 10 to April 9, 2020 [during the first period of national lockdown (in-LD)] and from May 18 to June 17, 2020 [soon after the end of all containment measures (after-LD)]. ⋯ This study confirms a notable reduction in the admissions to ICCUs from pre-LD to in-LD followed by an increment in the admission rates after-LD. These data strongly suggest that people, particularly women and patients with NSTEMI, are reluctant to seek medical care during lockdown, possibly due to the fear of viral infection. Such a phenomenon, however, was not associated with a rise in mortality among patients who get hospitalization.
