We will conduct a narrative synthesis of quantitative data and a thematic analysis of qualitative findings. Discussion We expect that our findings will contribute to improving the evidence-based general practice by identifying physicians perspectives about different sources of medical information.The current COVID-19 pandemic has the potential to overwhelm the capacity of hospitals and Intensive Care Units in Chile and Latin America. Thus local authorities have an ethical obligation to be prepared by implementing pertinent measures to prevent a situation of rationing of scarce healthcare resources, and by defining ethically acceptable and socially legitimate criteria for the allocation of these resources. This paper responds to recent ethical guidelines issued by a Chilean academic institution and discusses the main moral principles for the ethical foundations of criteria for rationing during the present crisis. It argues that under exceptional circumstances such as the current pandemic, the traditional patient-centered morality of medicine needs to be balanced with ethical principles formulated from a public health perspective, including the principles of social utility, social justice and equity, among others. The paper concludes with some recommendations regarding how to reach an agreement about rationing criteria and about their implementation in clinical practice.The authors informed the journal that several errors occurred in their manuscript and request the following to be corrected 1.

Measurement of the Combined Levels of Serum Uric Acid and Alanine Aminotransferase and the Risk of Metabolic Syndrome in a Population Aged 60 Years or More in Northeastern China. Med Sci Monit, 2020; 26 e916459. doi 10.12659/MSM.916459.BACKGROUND Papillary fibroelastoma accounts for approximately 24% of all primary cardiac tumors and is the third most common primary cardiac neoplasm. It mostly involves the cardiac valves; however, there have been cases of involvement of the endocardium. Papillary fibroelastoma, although typically benign, can cause a plethora of complications, including systemic embolization, myocardial infarction, arrhythmia, and sudden cardiac death. In this article we present a unique case of a man diagnosed with a papillary fibroelastoma of the right ventricle in the setting of multifocal pulmonary hemorrhages and pulmonary embolization. CASE REPORT A 39-year-old man presented with hemoptysis and dyspnea due to bilateral lower-lobe pneumonia and a left pleural effusion. Further imaging throughout his hospitalization revealed worsening multifocal consolidations, pulmonary hemorrhages, and a pulmonary embolus. A mobile cardiac mass measuring 30.2×20 mm, detected by echocardiography, was found in the right ventricle, partially fixed to the intraventricular septum via a 14.4-mm stalk, which was surgically excised and was found to be consistent with papillary fibroelastoma. He underwent an IVC filter and was discharged on warfarin, which he tolerated well. CONCLUSIONS Papillary fibroelastomas are benign infrequent findings but carry a high risk of systemic complications, as demonstrated in our patient. He had no known cardiac disease or risk factor for tumor growth, yet developed a papillary fibroelastoma of the right ventricle, which is rare. Given the potential of fatal outcomes, it is imperative that patients with unexplained embolic phenomena undergo early diagnosis by echocardiography and early surgical treatment.Objective To inform the current coronavirus disease 2019 (COVID-19) outbreak, we conducted a systematic literature review of case reports of Middle East respiratory syndrome coronavirus (MERS-CoV), severe acute respiratory syndrome coronavirus (SARS-CoV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, during pregnancy and summarized clinical presentation, course of illness, and pregnancy and neonatal outcomes. Data sources We searched MEDLINE and ClinicalTrials.gov from inception to April 23, 2020. see more Methods of study selection We included articles reporting case-level data on MERS-CoV, SARS-CoV, and SARS-CoV-2 infection in pregnant women. Course of illness, indicators of severe illness, maternal health outcomes, and pregnancy outcomes were abstracted from included articles. Tabulation, integration, and results We identified 1,328 unique articles, and 1,253 articles were excluded by title and abstract review. We completed full-text review on 75, and 29 articles ailable. The capture of critical data is needed to better define how this infection affects pregnant women and neonates. This review was not registered with PROSPERO.Individual state maternal mortality review committees aim to comprehensively review all maternal deaths to not only evaluate the cause of death, but also to assess preventability and make recommendations for action to prevent future deaths. The maternal mortality review committee process remains critical during the coronavirus disease 2019 (COVID-19) pandemic. Maternal deaths due to COVID-19 have been reported in the United States. Some state maternal mortality review committees may choose to expedite review of these deaths in an effort to quickly provide clinicians with information intended to prevent other deaths during the ongoing pandemic. If states opt to pursue rapid review, entry of data into the Maternal Mortality Review Information Application system for submission to the Centers for Disease Control and Prevention will allow for aggregation nationally without duplication. It will be important to review not only deaths directly attributed to COVID-19, but also those that may be indirectly related to the COVID-19 pandemic, such as those influenced by changes in care practices or delays in seeking care during the pandemic.
