Observational Study
Rehabilitation Levels in Patients with COVID-19 Admitted to Intensive Care Requiring Invasive Ventilation. An Observational Study.
Rationale: Patients with severe coronavirus disease (COVID-19) have complex organ support needs that necessitate prolonged stays in the intensive care unit (ICU), likely to result in a high incidence of neuromuscular weakness and loss of well-being. Early and structured rehabilitation has been associated with improved outcomes for patients requiring prolonged periods of mechanical ventilation, but at present no data are available to describe similar interventions or outcomes in COVID-19 populations. Objectives: To describe the demographics, clinical status, level of rehabilitation, and mobility status at ICU discharge of patients with COVID-19. ⋯ Conclusions: The early experience of the COVID-19 pandemic in the United Kingdom resembles the experience in other countries, with high acuity of illness and prolonged period of mechanical ventilation required for those patients admitted to the ICU. Although the time to commence rehabilitation was delayed owing to this severity of illness, rehabilitation was possible within the ICU and led to increased levels of mobility from waking before ICU discharge. Clinical trial registered with ClinicalTrials.gov (NCT04396197).

Coronavirus disease 2019 (COVID-19) first emerged in a group of patients who presented with severe pneumonia in Wuhan, China, in December 2019. A novel virus, now called SARSCoV- 2 (Severe Acute Respiratory Syndrome Coronavirus-2), was isolated from lower respiratory tract samples. The current outbreak of infection has spread to over 100 countries and killed more than 340,000 people as of 25th May, 2020. ⋯ Furthermore, COVID-19 infection has led to de novo cardiac complications, like acute myocardial injury and arrhythmias. In this review, we have focused on the cardiovascular manifestations of COVID-19 infection that have been reported in the literature so far. We have also outlined the effect of pre-existing cardiovascular disease as well as risk factors on the clinical course and outcomes of COVID-19 infection.

Multicenter Study Observational Study
Seroconversion in patients with cancer and oncology health care workers infected by SARS-CoV-2.
Patients with cancer have high risk for severe complications and poor outcome to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related disease [coronavirus disease 2019 (COVID-19)]. Almost all subjects with COVID-19 develop anti-SARS-CoV-2 immunoglobulin G (IgG) within 3 weeks after infection. No data are available on the seroconversion rates of cancer patients and COVID-19. ⋯ Our data indicate that SARS-CoV-2-specific IgG antibody detection do not differ between cancer patients and healthy subjects.

ReviewCurrent state of vaccine development and targeted therapies for COVID-19: impact of basic science discoveries.
Coronavirus disease-19 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 is closely related to two other coronaviruses that caused disease epidemic breakouts in humans in the last 2 decades, namely, severe acute respiratory distress syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). The similarities have enabled the scientists to apply the basic scientific discoveries garnered from studying the structure and modus operandi of SARS-CoV and MERS-CoV to develop therapies that specifically target SARS-CoV-2 and to develop vaccines to prevent COVID-19. ⋯ Likewise, complete sequencing of the SARS-CoV-2 and identification of its structural and nonstructural proteins have enabled development of RNA-, DNA-, and peptide-based vaccines as well attenuated viral vaccines to instigate the host-immune responses. The clinical impacts of the basic science discoveries are amply evident on the rapid pace of progress in developing specific antiviral therapies and vaccines against SARS-CoV-2. The progress emphasizes the merit of discovering the fundamental scientific elements, regardless of whether or not they have apparent or immediate clinical applications.

The first cases of COVID-19, caused by the virus called SARS-CoV-2, were recorded in Wuhan, China, in December 2019; however, its transmission ability caused for the infection to be practically present throughout the world six months later. The origin of the virus appears to be zoonotic; it has been proposed that it comes from a bat and that it may have had an intermediate host that led to its introduction in the human population. ⋯ Almost since the beginning of the epidemic, several molecules have been proposed for the treatment of infection; however, there is not yet a drug available with sufficient effectiveness for treatment. This review describes SARS-CoV-2 main characteristics, its replicative cycle, its possible origin and some advances in the development of antiviral treatments.
