The past few weeks, after the viewpoint surfaced, it was noticed that it has enabled clinicians and healthcare professionals to compute the neurovirulence associated with SARS-CoV-2 in COVID-19 patients, as evidenced by very recently reported studies.Atherosclerotic plaques exhibit high deposition of cholesterol and macrophages. NSC 644468 These are not only the main components of the plaques but also key inflammation-triggering sources. However, no existing therapeutics can achieve effective removal of both components within the plaques. Here, we report cargo-switching nanoparticles (CSNP) that are physicochemically designed to bind to cholesterol and release anti-inflammatory drug in the plaque microenvironment. CSNP have a core-shell structure with a core composed of an inclusion complex of methyl-β-cyclodextrin (cyclodextrin) and simvastatin (statin), and a shell of phospholipids. Upon interaction with cholesterol, which has higher affinity to cyclodextrin than statin, CSNP release statin and scavenge cholesterol instead through cargo-switching. CSNP exhibit cholesterol-sensitive multifaceted antiatherogenic functions attributed to statin release and cholesterol depletion in vitro. link2 In mouse models of atherosclerosis, systemically injected CSNP target atherosclerotic plaques and reduce plaque content of cholesterol and macrophages, which synergistically leads to effective prevention of atherogenesis and regression of established plaques. These findings suggest that CSNP provide a therapeutic platform for interfacing with cholesterol-associated inflammatory diseases such as atherosclerosis.The oxidation of nitric oxide to nitrogen dioxide by hydroperoxy (HO2) and organic peroxy radicals (RO2) is responsible for the chemical net ozone production in the troposphere and for the regeneration of hydroxyl radicals, the most important oxidant in the atmosphere. In Summer 2014, a field campaign was conducted in the North China Plain, where increasingly severe ozone pollution has been experienced in the last years. Chemical conditions in the campaign were representative for this area. Radical and trace gas concentrations were measured, allowing for calculating the turnover rates of gas-phase radical reactions. Therefore, the importance of heterogeneous HO2 uptake on aerosol could be experimentally determined. HO2 uptake could have suppressed ozone formation at that time because of the competition with gas-phase reactions that produce ozone. The successful reduction of the aerosol load in the North China Plain in the last years could have led to a significant decrease of HO2 loss on particles, so that ozone-forming reactions could have gained importance in the last years. However, the analysis of the measured radical budget in this campaign shows that HO2 aerosol uptake did not impact radical chemistry for chemical conditions in 2014. Therefore, reduced HO2 uptake on aerosol since then is likely not the reason for the increasing number of ozone pollution events in the North China Plain, contradicting conclusions made from model calculations reported in the literature.High-field asymmetric waveform ion mobility spectrometry (FAIMS) enables the separation of ions on the basis of their differential mobility in an asymmetric oscillating electric field. We, and others, have previously demonstrated the benefits of FAIMS for the analysis of peptides and denatured proteins. To date, FAIMS has not been integrated with native mass spectrometry of folded proteins and protein complexes, largely due to concerns over the heating effects associated with the high electric fields employed. Here, we demonstrate the newly introduced cylindrical FAIMS Pro device coupled with an Orbitrap Eclipse enables analysis of intact protein assemblies up to 147 kDa. No evidence for dissociation was detected suggesting that any field heating is insufficient to disrupt the noncovalent interactions governing these assemblies. Moreover, the FAIMS device was integrated into native liquid extraction surface analysis (LESA) MS of protein assemblies directly from thin tissue sections. Intact tetrameric hemoglobin (64 kDa) and trimeric reactive intermediate deiminase A (RidA, 43 kDa) were detected. Improvements in signal-to-noise of between 1.5× and 12× were observed for these protein assemblies on integration of FAIMS.During the coronavirus disease 2019 (COVID-19) pandemic, delaying lifesaving cancer surgeries must be done with extreme caution and thoughtfulness. Modelling indicates that delays in high-risk cancer surgeries beyond 6 weeks could affect long-term outcomes for thousands of Canadians. link3 Consequently, it is possible that postponing cancer surgery without consideration of its implications could cost more lives than can be saved by diverting all surgical resources to COVID-19. This article provides general guidance on supporting curative surgical treatment where appropriate and with available resources. © 2020 Joule Inc. or its licensors.OBJECTIVES To evaluate serum ferritin measured within 48 hours of admission as a prognostic marker and examine the association with unfavorable outcomes in a population of pediatric patients with sepsis and high prevalence of iron deficiency anemia in which this biomarker is routinely measured. DESIGN Retrospective cohort study. SETTING PICU of a tertiary care teaching hospital in a middle-income country in South America. PATIENTS All patients 6 months to 18 years old (n = 350) admitted with a diagnosis of sepsis, suspected or proven, were eligible for inclusion. Exclusion criteria were length of PICU stay less than 8 hours and inherited or acquired disorder of iron metabolism that could interfere with serum ferritin levels. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Three-hundred twelve patients had their ferritin levels measured within 48 hours, and only 38 did not. The prevalence of iron deficiency anemia (hemoglobin less then 11 g/dL and mean corpuscular volume less then 80 fl was 40.3%. The median of the highest serum ferritin level within 48 hours was 150.5 ng/mL (interquartile range, 82.25-362 ng/mL), being associated with mortality (p less then 0.001; Exp(B), 5.170; 95% CI, 2.619-10.205). A 10-fold increase in ferritin level was associated with a five-fold increase in mortality. There was a monotonic increase in mortality with increasing ferritin levels (p less then 0.05). Regarding the discriminatory power of ferritin for mortality, the area under the receiver operating characteristic curve was 0.787 (95% CI, 0.737-0.83; p less then 0.0001). CONCLUSIONS Serum ferritin at lower thresholds predicts mortality in children with sepsis admitted to the ICU in a middle-income country with high prevalence of iron deficiency anemia.OBJECTIVES Paralleling improved outcomes in critically ill patients, survival for pediatric acute kidney injury has improved. Continuous renal replacement therapy is the preferred modality to optimize fluid and electrolyte management as well as nutritional support for children developing acute kidney injury in the PICU. However, some patients remain too fragile for transition to intermittent renal replacement therapies and require continuous renal replacement therapy for a prolonged period. Characteristics of this cohort and factors impacting outcomes are not well known. We aimed to describe the characteristics of pediatric patients requiring prolonged continuous renal replacement therapy and evaluate the factors impacting hospital survival. DESIGN Retrospective chart review. SETTING Tertiary PICU. PATIENTS Children requiring prolonged continuous renal replacement therapy. Prolonged continuous renal replacement therapy was defined as continuous renal replacement therapy dependence greater than or equal to 28 he study group died from sepsis. Neutropenia at continuous renal replacement therapy initiation was associated with increased risk of mortality. Progression of underlying disease process could explain the higher death rate in patients with neutropenia; however, inadequate treatment of infectious complications could be another explanation to explore further in future studies.OBJECTIVES Viral infections are common in children, but there is a lack of data on severe viral infections in critically ill children. We investigated testing for viral infections in children requiring PICU admission and describe the epidemiology and outcomes. DESIGN Multicenter retrospective study. Results of viral testing for nine respiratory viruses using polymerase chain reaction were collected. PARTICIPANTS Children less than 16 years old nonelectively admitted to PICU over a 6-year period. SETTING Two tertiary PICUs in Queensland, Australia. INTERVENTIONS None. MAIN OUTCOME MEASURES Primary outcome was PICU length of stay. Secondary outcomes included need for and duration of intubation and mortality in PICU. Univariate and multivariate regression analyses were performed, adjusting for age, indigenous status, comorbidities, and severity of illness. RESULTS Of 6,426 nonelective admissions, 2,956 (46%) were polymerase chain reaction tested for a virus of which 1,353 (46%) were virus positive. Respiratory sultiple viruses and outcomes was observed. CONCLUSION Viral infections are common in critically ill children. Viral infections were associated with lower intubation and mortality rates compared with all children testing negative for viral infections. In several subgroups studied, identification of viral pathogens was associated with longer PICU length of stay while mortality was comparable. Prospective studies are required to determine the benefit of routine testing for respiratory viruses at the time of PICU admission.OBJECTIVES To assess risk factors for electronic prescription errors in a PICU. DESIGN A database of electronic prescriptions issued by a computerized physician order entry with clinical decision support system was analyzed to identify risk factors for prescription errors. MEASUREMENTS AND MAIN RESULTS Of 6,250 prescriptions, 101 were associated with errors (1.6%). The error rate was twice as high in patients older than 12 years than in patients children 6-12 and 0-6 years old (2.4% vs 1.3% and 1.2%, respectively, p less then 0.05). Compared with patients without errors, patients with errors had a significantly higher score on the Pediatric Index of Mortality 2 (-3.7 vs -4.5; p = 0.05), longer PICU stay (6 vs 3.1 d; p less then 0.0001), and higher number of prescriptions per patient (40.8 vs. 15.7; p less then 0.0001). In addition, patients with errors were more likely to have a neurologic main admission diagnosis (p = 0.008) and less likely to have a cardiologic diagnosis (p = 0.03) than patients without errors. CONCLUSIONS Our findings suggest that older patient age and greater disease severity are risk factors for electronic prescription errors.OBJECTIVES To examine the effects of patient and treatment variables on circuit lifespan in critically ill children requiring continuous renal replacement therapy. DESIGN Retrospective observational study based on a prospective registry. SETTING Tertiary referral 30-bed PICU. PATIENTS One hundred sixty-one critically ill children undergoing continuous renal replacement therapy during an 8-year period (2007-2014) were included in the study. INTERVENTIONS Continuous renal replacement therapy. MEASUREMENTS AND MAIN RESULTS During the study period, 161 patients received a total of 22,190 hours of continuous renal replacement therapy, with a median duration of 74.75 hours (interquartile range, 32-169.5) per patient. Of the 572 filter circuits used, 276 (48.3%) were changed due to circuit clotting and 262 (45.8%) were electively changed. Median circuit life was 24.62 hours (interquartile range, 10.6-55.3) for all filters and significantly longer for those electively removed as compared to those prematurely removed because of clotting (35.
