The association between enteral nutrition with survival of critical patients with COVID‐19

Background: Coronavirus disease 2019 (COVID‐19) results in several complications and mortality in intensive care unit (ICU) patients. Limited studies have investigated the effect of enteral nutrition (EN) on the survival of COVID‐19 patients in the ICU. The aim of this study was to investigate the association of EN with biochemical and pathological indices associated with mortality in ICU patients with COVID‐19. Methods: This case–control study was conducted on 240 patients with COVID‐19 hospitalized in the ICU including 120 eventual nonsurvived as the cases and 120 survived patients as the controls. All of the patients received EN as a high protein high volume or standard formula. Data on general information, anthropometric measurements, and the results of lab tests were collected. Results: The recovered patients received significantly more high protein (60.8% vs. 39.6%, p = .004) and high volume (61.6% vs. 42.3%, p = .005) formula compared to the nonsurvived group. Mortality was inversely associated with high volume (odds ratio [OR]: 0.45 confidence interval [CI]95%, p = .008) and high protein (OR: 0.42 CI95%, p = .003) formula. The results remained significant after adjusting for age and sex. Further adjustment for underlying diseases, smoking, body mass index, and the acute physiology and chronic health evaluation II (APACHE II) score did not change the results. Conclusion: The findings of the study showed that there was a significant inverse association between mortality and high volume and high protein formula in patients with COVID‐19. Further investigation is warranted

Environmental contamination of different areas of Isfahan province of Iran with Toxocara spp. eggs using molecular methods

Background: Toxocariasis is a parasitic disease caused by the larval stage of Toxocara canis and Toxocara cati. Infective stage of this parasite for human develops on soil. So, in this work contamination of the soil of public environments in five geographical areas of Isfahan province of Iran has been investigated. Materials and Methods: In this descriptive study, 355 soil samples were collected from parks, children's playgrounds, student dormitories, and university environments, and examined by Flotation method. The samples were then inspected using microscopic and molecular methods. Results: From the 355 examined soil samples in 77 (21.69%), and 87 (24.50%) cases Toxocara eggs were detected by microscopic and molecular methods, respectively. In the molecular method, 31 (8.70%) cases of T. cati and 44 (12.39%) cases of T. canis were identified. Conclusion: Toxocara eggs were identified in all areas of Isfahan province, although contamination rate was higher in Fereydun Shahr and Semirum counties
