Pericardial tamponade following long-term overall occlusion revascularization: a case record and also literature review.
Severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2), initially termed 2019-new CoV (2019-nCoV), is a novel coronavirus responsible for the severe respiratory illness currently ongoing worldwide from the beginning of December 2019. This beta gene virus, very close to bat coronaviruses (bat-CoV-RaTG13) and bat-SL-CoVZC45, causes a severe disease, similar to those caused by Middle East respiratory syndrome (MERS)-CoV and SARS-CoV viruses, featured by low to moderate mortality rate. Saracatinib molecular weight Unfortunately, the antiviral drugs commonly used in clinical practice to treat viral infections, are not applicable to SARS-Cov-2 and no vaccine is available. Thus, it is extremely necessary to identify new drugs suitable for the treatment of the 2019-nCoV outbreak. Different preclinical studies conducted on other coronaviruses suggested that promising clinical outcomes for 2019-nCoV should be obtained by using alpha-interferon, chloroquine phosphate, arabinol, remdesivir, lopinavir/ritonavir, and anti-inflammatory drugs. Moreover, clinical trials with these suitable drugs should be performed on patients affected by SARS-Cov-2 to prove their efficacy and safety. Finally, a very promising therapeutic drug, tocilizumab, is discussed; it is currently used to treat patients presenting COVID-19 pneumonia. Herein, we recapitulate these experimental studies to highlight the use of antiviral drugs for the treatment of SARS-Cov-2 disease.The Covid-19 pandemic is a world-wide crisis without an effective therapy. While most approaches to therapy are using repurposed drugs that were developed for other diseases, it is thought that targeting the biology of the SARS-CoV-2 virus, which causes Covid-19, can result in an effective therapeutic treatment. The coronavirus RNA cap structure is methylated by two viral methyltransferases that transfer methyl groups from S-adenosylmethionine (SAM). The proper methylation of the virus depends on the level of methionine in the host to form SAM. Herein, we propose to restrict methionine availability by treating the patient with oral recombinant methioninase, aiming to treat Covid-19. By restricting methionine we not only interdict viral replication, which depends on the viral RNA cap methyaltion, but also inhibit the proliferation of the infected cells, which have an increased requirement for methionine. Most importantly, the virally-induced T-cell- and macrophage-mediated cytokine storm, which seems to be a significant cause for Covid-19 deaths, can also be inhibited by restricting methionine, since T-cell and macrophrage activation greatly increases the methionine requirement for these cells. The evidence reviewed here suggests that oral recombinant methioninase could be a promising treatment for coronavirus patients.COVID-19 is viral respiratory infection with frequently fatal lung complications in the elderly or in people with serious comorbidities. Lung destruction appears to be associated with a cytokine storm related to an increased level of interleukin-6 (IL6). Therapeutic targeting of the interleukin-6 signaling pathway can attenuate such a cytokine storm and can be beneficial for patients with COVID-19 in danger of pulmonary failure. This article demonstrates the importance of IL6 in progression of disease and the possibility of inhibition of IL6 signaling in COVID-19 therapy.Background On March 11, 2020, the World Health Organization (WHO) declared the outbreak of coronavirus disease (COVID-19) a pandemic. Since then, thousands of people have suffered and died, making the need for a treatment of severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2) more crucial than ever. Materials and methods The authors carried out a search in PubMed, ClinicalTrials.gov and New England Journal of Medicine (NEJM) for COVID-19 to provide information on the most promising treatments against SARS-CoV-2. Results Possible COVID-19 agents with promising efficacy and favorable safety profile were identified. The results support the combination of copper, N-acetylcysteine (NAC), colchicine and nitric oxide (NO) with candidate antiviral agents, remdesivir or EIDD-2801, as a treatment for patients positive for SARS-CoV-2. Conclusion The authors propose to study the effects of the combination of copper, NAC, colchicine, NO and currently used experimental antiviral agents, remdesivir or EIDD-2801, as a potential treatment scheme for SARS-COV-2.Background Although there are considerable racial and ethnic disparities in prostate cancer incidence and mortality in the United States and globally, clinical trials often do not reflect disease incidence across racial and ethnic subgroups. This study aims to comprehensively review the reporting of race and ethnicity data and the representation of race and ethnicity across prostate cancer treatment-, prevention-, and screening-based clinical trials. Methods Seventy-two global phase III and IV prevention, screening, and treatment prostate cancer clinical trials with enrollment start dates between 1987 and 2016 were analyzed in this study, representing a total of 893,378 individual trial participants. Availability and representation of race and ethnicity data by trial funding type, temporal changes in the racial/ethnic diversity of participants, and geographic representation of countries were assessed. Results Of the 72 trials analyzed, 59 (81.9%) had available race data, and 11 (15.3%) of these trials additionally reported ethnicity. Of the trials reporting data, participants were overwhelmingly white men (with the highest proportion in U.S. nonpublicly funded trials), comprising over 96% of the study population. The proportion of white participants in prostate cancer clinical trials has remained at over 80% since 1990. Geographically, Africa and the Caribbean were particularly underrepresented with only 3% of countries included. Conclusions Trial participants continue to be majority white despite the known racial disparities in prostate cancer clinical outcomes. Impact Current and future trials must use novel recruitment strategies to ensure enrollment of underrepresented men. Targeting the inclusion of African and Caribbean medical centers is crucial to achieve equity in representation.
