Notes

Spectroscopic and practical characterization of the [2Fe-2S] scaffolding health proteins Nfu from Synechocystis PCC6803.
Hematopoietic stem/progenitor cells (HSPC) have both unique and common responses following hemorrhage, injury, and sepsis. HSPCs from different lineages have a distinctive response to these 'stress' signals. Inflammation, via the production of inflammatory factors, including cytokines, hormones, and interferons, has been demonstrated to impact the differentiation and function of HSPCs. In response to injury, hemorrhagic shock, and sepsis, cellular phenotypic changes and altered function occur, demonstrating the rapid response and potential adaptability of bone marrow hematopoietic cells. In this review, we summarize the pathophysiology of emergency myelopoiesis and the role of myeloid-derived suppressor cells, impaired erythropoiesis, as well as the mobilization of HSPCs from the bone marrow. Finally, we discuss potential therapeutic options to optimize HSPC function after severe trauma or infection.
We used lung ultrasonography to identify features of COVID-19 pneumonia and to evaluate the prognostic value.

We performed lung ultrasonography on 48 COVID-19 patients in an ICU (Wuhan, China) using a 12-zone method. The associations between lung ultrasonography score, PaO2/FiO2, APACHE II, SOFA, and PaCO2 with 28-day mortality were analyzed and the receiver operator characteristic curve was plotted.

25.9% areas in all scanning zones presented with B7 lines and 23.5% with B3 lines(B-pattern) on lung ultrasonography; 13% areas with confluent B lines(B-pattern), 24.9% in areas with consolidations, and 9.9% in areas with A lines. Pleural effusion was observed in 2.8% of areas. Lung ultrasonography score was negatively correlated with PaO2/FiO2 (n = 48, r = -0.498, P < 0.05) andpositively correlated with APACHE II (n = 48, r = 0.435, P < 0.05). Lung ultrasonography score was independently associated with 28-day mortality. The areas under ROC curves of lung ultrasonography score was 0.735 (95% CI 0.586-0.844). The sensitivity, specificity, and cutoff values were 0.833, 0.722, and 22.5, respectively.

Lung ultrasonography could be used to assess the severity of COVID-19 pneumonia, and it could also reveal the pathological signs of the disease. The lung ultrasonography score on ICU admission was independently related to the ICU 28-day mortality.

Because of the COVID-19 pandemic, education and learning processes have been shifted to a completely virtual, online format. Students' satisfaction has been linked to better learning outcomes.

The purpose was to determine factors associated with students' satisfaction with e-learning among Saudi nursing students.

A cross-sectional, correlational descriptive study was conducted among 139 nursing students from different nursing programs in Saudi Arabia using a self-reported online survey.

Previous experience with and readiness for e-learning influenced students' overall satisfaction with e-learning and satisfaction with assessment. see more Only readiness for e-learning was associated with satisfaction with teaching and generic skills and learning experiences.

This study may enhance faculty members' understandings of factors influencing students' satisfaction with e-learning. Therefore, the urgent national distance education plan may need further development to meet students' needs.

The COVID-19 pandemic initiated a period of new and difficult challenges for nursing students.

The aim of this study was to assess the change in levels of anxiety and ways of coping when the lockdown was being lifted compared with the period of the most severe lockdown restrictions.

First- to fourth-year nursing students in Israel (N = 244) completed 2 surveys conducted during the initial lockdown and 5 weeks later.

When the restrictions were lightened, the mean anxiety score decreased from 9.3 to 7.5 (P < .0001). Among Muslims students, the trend was the opposite, and anxiety levels increased. Stronger resilience was associated with lower odds for anxiety. Mental disengagement and information seeking were associated with higher anxiety levels.

The pandemic created unparalleled stressful situations for nursing students. Faculty should have heightened awareness of these stressors and act to implement innovative resolutions for the problems that arise.

Clinical performance evaluation is a high-stakes assessment that requires a valid and reliable instrument. There appear to be no identified clinical evaluation instruments developed for nurse practitioner (NP) students that have undergone content validation.

This study describes the process to develop, validate, and pilot a clinical evaluation instrument for NP students framed in the Quality and Safety Education of Nurses Competencies for advanced practice.

Six expert nurse educators were recruited for the purpose of rating items for relevance for inclusion in the Quality and Safety Framed Clinical Evaluation Instrument for NP Students using the content validity index. The instrument was pilot tested in a primary care clinical course.

Two rounds of review yielded a 34-item content validated instrument.

Evidence suggests that the Quality and Safety Framed Clinical Evaluation for NP Students is a valid and reliable instrument to evaluate the clinical performance of NP students.
