development of multiple malignant neoplasms without PTEN germline mutations, we confirmed the function of WWP1 as a cancer-susceptibility gene through direct aberrant regulation of the PTEN-PI3K signaling axis. (Funded by the National Institutes of Health and others.).Background Remdesivir is an RNA polymerase inhibitor with potent antiviral activity in vitro and efficacy in animal models of coronavirus disease 2019 (Covid-19). see more Methods We conducted a randomized, open-label, phase 3 trial involving hospitalized patients with confirmed SARS-CoV-2 infection, oxygen saturation of 94% or less while they were breathing ambient air, and radiologic evidence of pneumonia. Patients were randomly assigned in a 11 ratio to receive intravenous remdesivir for either 5 days or 10 days. All patients received 200 mg of remdesivir on day 1 and 100 mg once daily on subsequent days. The primary end point was clinical status on day 14, assessed on a 7-point ordinal scale. Results In total, 397 patients underwent randomization and began treatment (200 patients for 5 days and 197 for 10 days). The median duration of treatment was 5 days (interquartile range, 5 to 5) in the 5-day group and 9 days (interquartile range, 5 to 10) in the 10-day group. At baseline, patients randomly assigned to the 10-day group had significantly worse clinical status than those assigned to the 5-day group (P = 0.02). By day 14, a clinical improvement of 2 points or more on the ordinal scale occurred in 64% of patients in the 5-day group and in 54% in the 10-day group. After adjustment for baseline clinical status, patients in the 10-day group had a distribution in clinical status at day 14 that was similar to that among patients in the 5-day group (P = 0.14). The most common adverse events were nausea (9% of patients), worsening respiratory failure (8%), elevated alanine aminotransferase level (7%), and constipation (7%). Conclusions In patients with severe Covid-19 not requiring mechanical ventilation, our trial did not show a significant difference between a 5-day course and a 10-day course of remdesivir. With no placebo control, however, the magnitude of benefit cannot be determined. (Funded by Gilead Sciences; GS-US-540-5773 ClinicalTrials.gov number, NCT04292899.).Background Many reports on coronavirus disease 2019 (Covid-19) have highlighted age- and sex-related differences in health outcomes. More information is needed about racial and ethnic differences in outcomes from Covid-19. Methods In this retrospective cohort study, we analyzed data from patients seen within an integrated-delivery health system (Ochsner Health) in Louisiana between March 1 and April 11, 2020, who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, the virus that causes Covid-19) on qualitative polymerase-chain-reaction assay. The Ochsner Health population is 31% black non-Hispanic and 65% white non-Hispanic. The primary outcomes were hospitalization and in-hospital death. Results A total of 3626 patients tested positive, of whom 145 were excluded (84 had missing data on race or ethnic group, 9 were Hispanic, and 52 were Asian or of another race or ethnic group). Of the 3481 Covid-19-positive patients included in our analyses, 60.0% were female, 70.4% were black no.89; 95% confidence interval, 0.68 to 1.17). Conclusions In a large cohort in Louisiana, 76.9% of the patients who were hospitalized with Covid-19 and 70.6% of those who died were black, whereas blacks comprise only 31% of the Ochsner Health population. Black race was not associated with higher in-hospital mortality than white race, after adjustment for differences in sociodemographic and clinical characteristics on admission.In the presented review of the book N.R. Efimochkina “Bacterial food pathogens of the Campylobacter genus” (Moscow, 2019) attention is drawn to the safety of food products and food raw materials, especially poultry products for consumers. In general, the problematic issues of campylobacteriosis and its causative agent are highlighted in a new way the main reservoirs, sources and factors of pathogen transmission are indicated, theoretical issues are analyzed and generalized data of screening studies of food products and environmental objects in the poultry industry for bacteria of the genus Campylobacter are presented. Particular attention is paid to laboratory diagnostics of the pathogen for the presence of uncultivated forms of these pathogens, the existence of Campylobacter in biofilms, and the resistance of isolated cultures to antibiotics. Laboratory methods that improve the detection of these pathogens are proposed. The developed methodological documents that accelerate the processes of Campylobacter isolation and antibiotic resistance assessment are relevant, which is important for the efficiency of production control and sanitary inspections of poultry and meat processing enterprises at control critical points. The introduction of the methods described in the monograph for analyzing the content of Campylobacter in food products, on the surface of equipment and inventory will help to effectively manage the risks associated with contamination of food products by these pathogens. The monograph will be of great importance for improving the knowledge of a number of medical staff, including sanitary and hygienic profile, that is important for environmental protection, the prevention of food poisoning and intestinal infections with alimentary transmission factor.The enrichment of food products of industrial production in order to replenish vitamin and mineral deficiency is an actual trend in optimizing the diet of adults and children. Enriched milk as a healthy food is in constant demand. In this regard, monitoring the content of nutrients declared by the manufacturer in fortified milk and identification of its assortment is an important task. The aim of the research was assessment of the content of vitamins and mineral substances as micronutrients that form a balanced diet, in enriched milk marketed in Kemerovo. Material and methods. The content of micronutrients declared by the manufacturer in the information on the individual product label has been determined vitamins C and B1; mineral substances (calcium, iron, iodine, zinc) in 10 samples of fortified drinking milk with a fat content of 2.5% from different manufacturers. Iron was determined by colorimetric method based on measuring the color intensity of red solution of a complex compound of divalent iron with ortho-phenanthroline.
