The RECOVERY study documented lower 28-day mortality with the use of dexamethasone in hospitalized patients on invasive mechanical ventilation or oxygen with COVID-19 Pneumonia. We aimed to examine the practice patterns of steroids use, and their impact on mortality and length of stay in ICU. We retrospectively examined records of all patients with confirmed Covid 19 pneumonia admitted to the ICU of Dubai hospital from January 1st, 2020 - June 30th, 2020. We assigned patients to four groups (No steroids, low dose, medium dose, and high dose steroids). The primary clinical variable of interest was doses of steroids. Secondary outcomes were 28-day mortality and length of stay in ICU". We found variability in doses of steroid treatment. The most frequently used dose was the high dose. Patients who survived were on significantly higher doses of steroids and had significantly longer stays in ICU. The prescription of steroids in Covid-19 ARDS is variable. The dose of steroids impacts mortality rate and length of stay in ICU, although patients treated with high dose steroids seem to stay more days in ICU.

Background COVID-19 has caused 4 million deaths as of 24 August 2021. A significant number of patients were admitted to undesignated ICU areas before transfer to a desig-nated ICU owing to the unavailability of ICU beds. We aim to compare the mortality and length of stay of patients in these 2 areas. Methods We retrospectively studied all critically ill patients with COVID-19 pneumonia who were admitted to Dubai hospital between 1 January 2020 and 30 June 2020. Patients who transferred to wards other than designated ICU constitute cases, while those who were admitted directly to designated ICUs constitute controls. The demographics, clinical parameters, and treatment profile of these patients were recorded and compared. Mortality and length of stay were calculated. Results The sample includes 239 subjects (admitted to an undesignated ICU ward [n = 107] and directly admitted to a designated ICU ward [n = 132]). Patients admitted to an undesignated ICU had extra transfers between wards and had more days on MV (median [IQR] 18 (19) vs. 11 (14); P = 0.001), greater length of stay in the ICU (median [IQR]) 21.5 (19) vs. 15 (14); P = 0.001), and greater length of stay in hospital (median [IQR] 32 (28) vs. 21 (26); P = 0.001). Multiple logistic regression analysis showed that patients treated at an undesignated ICU have better survival (odds of death for patients cared for at an undesignated ICU was 0.347 with CI 0.178–0.676; P = 0.002). Multiple linear regression analysis also showed that patients treated at an undesignated ICU had longer stay – 4.2 days, CI 1.3–7.13, P = 0.004). Conclusions Admission to an undesignated ICU impacts mortality and length of ICU and hospital stay.

Introduction: Bloodstream infections are one of the leading causes of mortality and morbidity. Time to positive blood culture may be reflective of the severity of infection. We aim to study the impact of time to positivity (TTP) of blood culture upon clinical outcome. Methods: Data from blood cultures for 17 months duration reviewed. Outcome measures included in-hospital mortality and length of stay in ICU (LOSICU). TTP was determined for each sample. Demographics (age, gender, BMI, and nationality), APACHE-2 score for severity of illness, comorbid conditions, and other confounding factors were recorded. Results: One hundred and one patients with 346 positive blood cultures with mean age of 62 and mean APACHE-2 score of 18.9 + 9.7 (mean +SD) with overall observed mortality of 61%. Median TTP was 20.2 h with quartiles cutoff Q1 = 15.3, Q2 = 20.2, Q3 = 28, and range 8–104 h. Only APACHE-2 scores predict LOSICU. TTP is not a significant predictor for mortality or LOSICU. Discussion: Data on TTP of blood cultures have a complex interaction with clinical outcomes. Conclusion: TTP of blood cultures does not predict mortality or length of stay in ICU.

The Representation of Animals in Selected Plays by Edward Albee Starting from the 90s, critics began to highlight the importance not only of creating ecological based drama, but also of rereading and reinterpreting plays from an ecocritical standpoint. Applying ecocriticism to theatre studies involves showing the political significance of elements such as landscape and animal bodies on stage. The burgeoning field of animal studies has allowed critics to examine the significance of the representation of animals in literary works. Animal studies main aim is to bring "the question of the animal" to the forefront of the field of criticism. It also aims at examining and questioning the ideologies and the various discourses that created the gap between human and nonhuman animals. It is concerned with how animals are represented both literary and socially. The Zoo Story (1958) and Seascape (1975) are two plays written by Edward Albee. Although animal ubiquity cannot be missed in both texts, yet the main focus of critics was usually on the human protagonists. Approaching the two plays from animal studies and posthumanist perspectives reveals the ideological connotations upon which the distinction between human and nonhuman animals is constructed. The thesis consists of a preface, three chapters and a conclusion. Chapter 1 entitled “Theatre and Animal Studies” introduces the relation between ecocriticism and theatre as well as the emergence of the field of critical animal studies. Chapter 2 “The Animal Gaze in The Zoo Story” deals with the gaze of the animal and how it defines the relationship between human and nonhuman animals. Chapter 3 “Breaking Boundaries in Seascape” shows how that the corporeal experience can free both human and nonhuman animals from the ideological constructions that defined their relation for centuries reminding us that humans themselves are inherently animals.

In this study, we isolated and characterized three phages named as Salmacey1, Salmacey2 and Salmacey3, infecting multi drug resistant Salmonella serovars isolated from broilers in Egypt. The most prevalent Salmonella serovars were S. typhimurium, S. enteritidis, and S. kentucky. All these Salmonella serovars were found to be resistant to more than two of the ten antimicrobial agents tested. Only S. kentucky was found to be resistant to seven antimicrobial agents. Examination of these phage particles by transmission electron microscopy (TEM), demonstrated that two phages (Salmacey1, Salmacey2) were found to belong to family Siphoviridae, and Salmacey3 was assigned to the family Myoviridae. The results of host range assay revealed that these bacteriophages were polyvalent and thus capable of infecting four strains of Salmonella serovars and Citrobacter freundii. Moreover, the two phages (Salmacey1, Salmacey2) had a lytic effect on Enterobacter cloacae and Salmacey3 was able to infect E. coli. All phages could not infect S. para Typhi, Staphylococus aureus and Bacillus cereus. One-step growth curves of bacteriophages revealed that siphovirus phages (Salmacey1, Salmacey2) have burst size (80 and 90 pfu per infected cell with latent period 35 min and 40 min respectively), and for the myovirus Salmacey3 had a burst size 110 pfu per infected cell with latent period 60 min. Molecular analyses indicated that these phages contained double-stranded DNA genomes. The lytic activity of the phages against the most multidrug resistant serovars S. kentucky as host strain was evaluated. The result showed that these bacteriophages were able to completely stop the growth of S. kentucky in vitro. These results suggest that phages have a high potential for phage application to control Salmonella serovars isolated from broilers in Egypt.
