The COVID-19 pandemic declared in March 2020, has generated worldwide concern due to its effect on the health of the population and the potential health collapse. The strategy of "flattening the curve" through social distancing made it possible to adapt the resources of the health system to patients with COVID-19, but results in other areas of health could not be predicted. The objective of this work was to analyze the consequences of the pandemic on liver transplantation in general and for hepatocarcinoma (HCC). The following studies were carried out a) a retrospective analysis using data from the CRESI / INCUCAI to compare admission to the waiting list, mortality on the list, donation and liver transplantation from 03/20 to 08/15, 2019 and the same period in 2020, and b) a survey of the transplant centers with the highest transplant activity to assess the effect of the measures taken in different institutional and regional situations. The first analysis showed a 55% decrease in liver transplants, with a similar reduction in donation and admission to the liver waiting list; while HCC transplantation rose from 10% in 2019 to 22% in 2020. The second analysis showed that the occupancy rate of beds by COVID-19 patients / week was variable from 0.4% to 42.0%. The number of surgeries, hepato-bilio-pancreatic, resection of HCC and liver transplantation, were reduced by 47%, 49%, 31% and 36% respectively. The reduction in transplant activity mainly affected centers with high occupancy due to COVID-19. The final long-term outcome will need to be assessed.The COVID-19 pandemic and preventive and compulsory social isolation (PCSI) have generated changes in the organization and use of the health system around the world. We analyze the impact of the health situation on the number of outpatient visits, hospitalizations and access to revascularization therapy for cerebrovascular disease. The period from March 1 to July 31, 2020 was analyzed. It was compared with the same period in 2019. Total outpatient and hospital visits were evaluated, NIHSS scale (National Institute of Health Stroke Scale) upon admission, type of cerebrovascular disease and use of revascularization therapies; 197 patients with acute cerebrovascular events were admitted in 2019 and 150 patients in 2020. There was a significant decrease in the number of hospitalizations for total ischemic events and transient ischemic attacks in the comparison of 5 months.  https://www.selleckchem.com/products/Cyclopamine.html  An increase in cerebral venous thrombosis and cerebral hemorrhages was also seen. Access to intravenous fibrinolysis and mechanical thrombectomy remained stable, but with prolonged door-to-needle time. Outpatient visits fell 67%, the decrease being greater in April and more marked in follow-up visits. The number of hospitalizations and outpatient visits during the PCSI dropped substantially. This seems to be due to strict compliance with quarantine and not to pathophysiological mechanisms related to COVID-19. The population should be educated about the need to control chronic diseases and acute events and safety measures should be guaranteed in health centers.The clinical features of COVID-19 differ substantially upon the presence (or absence) of viral pneumonia. The aim of this article was to describe the clinical characteristics of COVID-19 patients admitted to the Internal Medicine ward, as divided into those with and without pneumonia. This single-center prospective cohort study was conducted in a tertiary teaching public hospital in Buenos Aires City named Hospital General de Agudos Carlos G. Durand. Baseline data collection was performed within 48 hours of admission and patients were followed until discharge or in-hospital death. Epidemiological, clinical, laboratory, and radiological characteristics together with treatment data were obtained from the medical records. Of the 417 included, 243 (58.3%) had pneumonia. Median age was 43 years (IQR32-57) and 222 (53.2%) were female. The overall crude case-fatality rate was 3.8%. None of the COVID-19 patients without pneumonia developed critical disease, required invasive mechanical ventilation nor died during hospitalization. However, 7 (4%) developed severe disease during follow-up. Among patients with COVID-19 pneumonia, in-hospital mortality rate was 6.6%, severe disease developed in 81 (33.3%), critical disease in 23 (9.5%), and 22 (9.1%) were admitted to the intensive care unit. A largely good prognosis was observed among COVID-19 patients without pneumonia, still, even among this group, unfavorable clinical progression can develop and should be properly monitored. Critical illness among patients with COVID-19 pneumonia was frequent and observed rates from this cohort provide a sound characterization of COVID-19 clinical features in a major city from South America.This retrospective descriptive study analyzes the clinical and epidemiological characteristics, the disease evolution and its association with laboratory markers of poor prognosis of the first 100 patients with COVID-19 admitted to internal medicine wards at the Hospital de Clínicas José de San Martín, University of Buenos Aires. Thirty-one patients were nursing home residents, the most common clinical manifestations were fever, cough and odynophagia. Regarding comorbidities, obesity was the most frequent one and hypertension was the most prevalent in patients with pneumonia. The most important predictors of mortality were age and pneumonia. Patients older than 70 years had higher acute phase reactants showing an exaggerated inflammatory response. Mortality was high (13%), compared to most reports (5%), probably because of the advanced age of our population and the unfavorable clinical conditions they presented at admission.The Coronavirus Disease 2019 (COVID-19) pandemic has strained the world's health systems, highlighting the need to optimize its clinical management and treatment. The usefulness of blood cultures in patients with COVID-19 pneumonia has not been proved. We aim to describe the diagnostic yield of early blood cultures in patients with COVID-19 pneumonia in a public hospital in Buenos Aires City. This descriptive observational study included all adult patients with COVID-19 pneumonia admitted to the Internal Medicine ward of Hospital Durand between April 1, 2020 and July 30, 2020, who had blood cultures drawn within 5 days from hospital admission. Among 267 patients hospitalized with COVID-19 pneumonia, 38 had early blood cultures drawn. No clinically relevant microorganism was isolated from blood and contaminant microorganisms were recovered in 7 (18.4%) patients. This study found no evidence of bacteremia in patients with COVID-19 pneumonia. Furthermore, the rate of contaminated blood cultures nearly doubles the reported in patients with community acquired pneumonia (10%), which may be explained by unfamiliarity of additional personal protective equipment worn by healthcare workers.
