A social learning theory model for understanding team-based professional communication learning for computer science students

The study interrogates an annual course with undergraduate computer science students that takes place against the background of national student protests at universities across South Africa to effect equitable access to universities. It uses reflections by computer science students of their experience of collaborative work on a Scenario Pedagogy (SP) course, as well as the results of a survey of student collaborative practices in a digital space as a window into their learning trajectories. The study demonstrates and offers an understanding of how SP can contribute to developing computer science students as communicators in their discipline at university and future workplaces. It explores the usefulness of Communities of Practice (COP) and Knowledgeability across Landscapes of Practice (KLP) theory as an analytical tool-set as well as a descriptive language for investigating and explaining learning events. The changing and changed landscape of higher education and the world of work present new challenges and opportunities, particularly in curriculum development and delivery. Utilising “authentic” pedagogies and social learning theory provides appropriate tools for meeting these challenges. Exploring reflective practices and their contribution to the emerging of transformed practices and identities in the South African higher education sector would be a fruitful avenue of future research

Is cytomegalovirus reactivation increasing the mortality of patients with severe sepsis?

Cytomegalovirus (CMV) is a ubiquitous virus present in approximately two-thirds of the healthy population. This virus rarely causes an active disease in healthy individuals, but it is among the most common opportunistic infections in immunocompromised patients such as solid organ transplant recipients, patients receiving chemotherapy for cancer or patients with human immunodeficiency virus. Critically ill patients who are immunocompetent before intensive care unit admission may also become more prone to develop active CMV infection if they have prolonged hospitalizations, high disease severity, and severe sepsis. The development of active CMV infection in these critically ill patients has been associated with a significantly higher risk of death in several previous studies. The present issue of Critical Care brings a new study by Heininger and colleagues in which the authors found that patients with severe sepsis who developed active CMV infection had significantly longer intensive care unit and hospital stays, prolonged mechanical ventilation, but no changes in mortality compared to patients without CMV infection. We discuss the possible reasons for their findings (for example, selection bias and low (20%) statistical power to detect mortality endpoints), and also perform an update of our previous meta-analysis with the addition of Heininger and colleagues' study to verify whether the higher mortality rate with CMV holds. Our updated meta-analysis with approximately 1,000 patients shows that active CMV infection continues to be associated with a significant 81% higher mortality rate than that in critically ill patients without active CMV infection

Baricitinib plus Remdesivir for Hospitalized Adults with Covid-19

BACKGROUND: Severe coronavirus disease 2019 (Covid-19) is associated with dysregulated inflammation. The effects of combination treatment with baricitinib, a Janus kinase inhibitor, plus remdesivir are not known. METHODS: We conducted a double-blind, randomized, placebo-controlled trial evaluating baricitinib plus remdesivir in hospitalized adults with Covid-19. All the patients received remdesivir ( \u3c /=10 days) and either baricitinib ( \u3c /=14 days) or placebo (control). The primary outcome was the time to recovery. The key secondary outcome was clinical status at day 15. RESULTS: A total of 1033 patients underwent randomization (with 515 assigned to combination treatment and 518 to control). Patients receiving baricitinib had a median time to recovery of 7 days (95% confidence interval [CI], 6 to 8), as compared with 8 days (95% CI, 7 to 9) with control (rate ratio for recovery, 1.16; 95% CI, 1.01 to 1.32; P = 0.03), and a 30% higher odds of improvement in clinical status at day 15 (odds ratio, 1.3; 95% CI, 1.0 to 1.6). Patients receiving high-flow oxygen or noninvasive ventilation at enrollment had a time to recovery of 10 days with combination treatment and 18 days with control (rate ratio for recovery, 1.51; 95% CI, 1.10 to 2.08). The 28-day mortality was 5.1% in the combination group and 7.8% in the control group (hazard ratio for death, 0.65; 95% CI, 0.39 to 1.09). Serious adverse events were less frequent in the combination group than in the control group (16.0% vs. 21.0%; difference, -5.0 percentage points; 95% CI, -9.8 to -0.3; P = 0.03), as were new infections (5.9% vs. 11.2%; difference, -5.3 percentage points; 95% CI, -8.7 to -1.9; P = 0.003). CONCLUSIONS: Baricitinib plus remdesivir was superior to remdesivir alone in reducing recovery time and accelerating improvement in clinical status among patients with Covid-19, notably among those receiving high-flow oxygen or noninvasive ventilation. The combination was associated with fewer serious adverse events. (Funded by the National Institute of Allergy and Infectious Diseases; ClinicalTrials.gov number, NCT04401579.)

Mothers\u27 Work and Children\u27s Lives: Low-Income Families after Welfare Reform

This book examines the effects of work requirements imposed by welfare reform on low-income women and their families. The authors pay particular attention to the nature of work—whether it is stable or unstable, the number of hours worked in a week and the regularity and flexibility of work schedules. They also show how these factors make it more difficult for low-income women to balance their work and family requirements.https://research.upjohn.org/up_press/1026/thumbnail.jp
