Background Some physicians in intensive care units (ICUs) report that electronic health records (EHRs) can be cumbersome and disruptive to workflow. There are significant gaps in our understanding of the physician-EHR interaction. Objective To better understand how clinicians use the EHR for chart review during ICU pre-rounds through the characterisation and description of screen navigation pathways and workflow patterns. Method We conducted a live, direct observational study of six physician trainees performing electronic chart review during daily pre-rounds in the 30-bed medical ICU at a large academic medical centre in the Southeastern United States. A tailored checklist was used by observers for data collection. Results We observed 52 distinct live patient chart review encounters, capturing a total of 2.7 hours of pre-rounding chart review activity by six individual physicians. Physicians reviewed an average of 8.7 patients (range = 5-12), spending a mean of 305 minutes per patient (range = 134-518). On average, physicians visited 6.3 (±3.1) total EHR screens per patient (range = 1-16). Four unique screens were viewed most commonly, accounting for over half (52.7%) of all screen visits results review (17.9%), summary/overview (13.0%), flowsheet (12.7%), and the chart review tab (9.1%). Navigation pathways were highly variable, but several common screen transition patterns emerged across users. Average interrater reliability for the paired EHR observation was 80.0%. Conclusion We observed the physician-EHR interaction during ICU pre-rounds to be brief and highly focused. Although we observed a high degree of "information sprawl" in physicians' digital navigation, we also identified common launch points for electronic chart review, key high-traffic screens and common screen transition patterns. Implications From the study findings, we suggest recommendations towards improved EHR design.Five previously undescribed flavonoids (1-5) and ten known ones (6-15) were isolated from the roots of Oxybaphus himalaicus. Their structures were elucidated by spectroscopic experiments including NMR, HRESIMS and ECD. The cytotoxic activities of all isolated compounds were assayed against human lung carcinoma A549 cells and human hepatocellular carcinoma HepG2 cells in vitro. Compound 11 displayed the most powerful inhibitory effect with IC50 values of 19.47 ± 0.28 μM against A549 and 52.6 ± 0.38 μM against HepG2, respectively.Diffuse pulmonary inflammation, endothelial inflammation and enhanced thrombosis are cardinal features of COVID-19, the disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). These features are reminiscent of several adverse reactions triggered by angiotensin II, and opposed by angiotensin1-7, in many experimental models. SARS-CoV-2 binds to ACE2 receptors and entries into the cell through the fusion of its membrane with that of the cell. Hence, it down-regulates these receptors. The loss of ACE2 receptor activity from the external site of the membrane will lead to less angiotensin II inactivation and less generation of antiotensin1-7. [https://www.selleckchem.com/products/gambogic-acid.html https://www.selleckchem.com/products/gambogic-acid.html] In various experimental models of lung injury, the imbalance between angiotensin II over-activity and of antiotensin1-7 deficiency triggered inflammation, thrombosis and other adverse reactions. In COVID-19, such imbalance could play an important role in influencing the clinical picture and outcome of the disease. According to this line of thinking, some therapeutic approaches including recombinant ACE2, exogenous angiotensin1-7 and angiotensin receptor blockers appear particularly promising and are being actively tested.Mistranslation occurs when an amino acid not specified by the standard genetic code is incorporated during translation. Since the ribosome does not read the amino acid, tRNA variants aminoacylated with a non-cognate amino acid or containing a non-cognate anticodon dramatically increase the frequency of mistranslation. In a systematic genetic analysis, we identified a suppression interaction between tRNASerUGG, G26A, which mistranslates proline codons by inserting serine, and eco1-1, a temperature sensitive allele of the gene encoding an acetyltransferase required for sister chromatid cohesion. The suppression was partial with a tRNA that inserts alanine at proline codons and not apparent for a tRNA that inserts serine at arginine codons. Sequencing of the eco1-1 allele revealed a mutation that would convert the highly conserved serine 213 within β7 of the GCN5-related N-acetyltransferase core to proline. Mutation of P213 in eco1-1 back to the wild-type serine restored function of the enzyme at elevated temperature. Our results indicate the utility of mistranslating tRNA variants to identify functionally relevant mutations and identify eco1 as a reporter for mistranslation. We propose that mistranslation could be used as a tool to treat genetic disease.Background Performing physical activity whilst exposed to nature can improve health. However, there is little evidence of its impact on stress outcomes. The aim of this study was to examine the influence of the visual exercise environment on the response to a psychosocial stressor.Methods Eighteen participants were randomized to one of three conditions i. nature; ii. built or; iii. control condition. Participants exercised for 30 min on a treadmill at 50% of their VO2max whilst viewing a video of either a natural or built environment or a blank screen. Following the exercise, participants completed the Trier Social Stress Test (TSST), a standardized laboratory stressor. Salivary samples were collected before, during and after the TSST to calculate cortisol reactivity and recovery.Results One-way ANOVA revealed a significant effect of viewing condition on cortisol reactivity [F(2, 11) = 4.686, p = .034; n2 p = .460]; with significantly lower reactivity in the built compared to the nature condition (p = .027, d = 1.73). There was no effect of condition on cortisol recovery (p = .137; n2 p = .257).Conclusions In the context of the adverse health impact of lower (i.e., blunted) cortisol responding, these findings could indicate a negative impact of the built environment on stress responses.
