Angiotensin-Converting Enzyme 2 (ACE2) has been proved to be the main host cell receptor for the binding of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the COVID-19 pandemic. The SARS-CoV-2 spike (S) protein binds to ACE2 to initiate the process of replication. This enzyme is widely present in human organ tissues, such as the heart and lung. The pathophysiology of ACE2 in SARS-CoV-2 infection is complex and may be associated with several factors and conditions that are more severe in COVID-19 patients, such as age, male gender, and comorbidities, namely, cardiovascular diseases, chronic respiratory diseases, obesity, and diabetes. Here we present a comprehensive review that aims to correlate the levels of expression of the in patients with comorbidities and with a poor outcome in COVID-19 disease. Significantly higher levels of expression of were observed in myocardial and lung tissues in heart failure and COPD patients, respectively. An age-dependent increase in SARS2-CoV-2 receptors in the respiratory epithelium may be also responsible for the increased severity of COVID-19 lung disease in elderly people. Although the role of ACE2 is highlighted regarding the damage that can arise upon the SARS-CoV-2 invasion, there was no association observed between renin-angiotensin-aldosterone system (RAAS) inhibitors and the severity of COVID-19.

Purpose: Neuropathic corneal pain (NCP) has been recognized as a distinct disease, yet treatment options remain limited. The aim of this pilot study was to explore the effectiveness of extranasal neurostimulation (EXNS) as a potential pain relief strategy for individuals with the peripheral component of NCP.
Methods: A retrospective study was performed to identify patients who were diagnosed with refractory peripheral or mixed NCP and subsequently underwent a single session of EXNS.

Importance: A growing body of literature suggests the presence of a prodromal period with nonspecific signs and symptoms before onset of multiple sclerosis (MS).
Objective: To systematically assess diseases and symptoms diagnosed in the 5 years before a first MS- or central nervous system (CNS) demyelinating disease-related diagnostic code in pediatric patients compared with controls without MS and controls with another immune-mediated disorder, juvenile idiopathic arthritis (JIA).
Design, Setting, And Participants: This population-based, matched case-control study included children and adolescents (aged <18 years) in Germany with statutory health insurance from January 2010 to December 2020.

Introduction: Medication regimen complexity may be an important risk factor for adverse outcomes in older adults with heart failure. However, increasing complexity is often necessary when prescribing guideline-directed medical therapy at the time of a heart failure hospitalization. We sought to determine whether increased medication regimen complexity following a heart failure hospitalization was associated with worse post-hospitalization outcomes.

Objectives: With the prolongation of life expectancy in patients with myasthenia gravis, the number of comorbidities is increasing. Diabetes mellitus is one of the main comorbidities faced by patients with myasthenia gravis. However, there is not enough epidemiological information on diabetes mellitus.

Background: The purpose of this study was to test the impact of Function Focused Care for Acute Care Using the Evidence Integration Triangle (FFC-AC-EIT) on hospitalized patients living with dementia.
Methods: This was a clustered randomized clinical trial including 12 hospitals from two states and 455 patients living with dementia. Hospitals were randomized to FFC-AC-EIT versus FFC Education Only.
