Acute myeloid leukemia (AML) is a caricature of normal hematopoiesis, driven from leukemia stem cells (LSC) that share some hematopoietic stem cell (HSC) programs including responsiveness to inflammatory signaling. Although inflammation dysregulates mature myeloid cells and influences stemness programs and lineage determination in HSC by activating stress myelopoiesis, such roles in LSC are poorly understood. Here, we show that S1PR3, a receptor for the bioactive lipid sphingosine-1-phosphate, is a central regulator which drives myeloid differentiation and activates inflammatory programs in both HSC and LSC. S1PR3-mediated inflammatory signatures varied in a continuum from primitive to mature myeloid states across AML patient cohorts, each with distinct phenotypic and clinical properties. S1PR3 was high in LSC and blasts of mature myeloid samples with linkages to chemosensitivity, while S1PR3 activation in primitive samples promoted LSC differentiation leading to eradication. Our studies open new avenues for therapeutic target identification specific for each AML subset.
To assess whether composite polymer resin delivered in compules include pores and the possible effect on the amount of porosity in dental restorations.

Original compules containing unpolymerised composite polymer resin (CPR) were scanned in a micro-CT. Four products were examined, which comprised universal composites (Herculite XRV Ultra, Ceram.X Universal, Tetric Evo Ceram) and a flowable bulk-fill composite (SDR) (
 = 10 per group). The pore size distribution and amount of porosity (vol.%) were estimated for the unpolymerized and polymerized material used to restore a standardised cavity in a typodont tooth. CaMK inhibitor Manufacturers' instructions were followed regarding material handling, and polymerisation by use of a calibrated light-curing unit. The pore characteristics and their size distribution, and the amount of porosity in the dental restoration were contrasted with the values measured in the compule. Non-parametric tests were used to analyse differences between the four products.

All the composite polyporosity (p  less then  .01).The main objective of this study was to evaluate trends in set tidal volumes across all adult ICUs at a large academic medical center over 6 years, with a focus on adherence to lung-protective ventilation (≤ 8-cc/kg ideal body weight). A secondary objective was to survey providers on their perceptions of lung-protective ventilation and barriers to its implementation.
Retrospective observational analysis (primary objective) and cross-sectional survey study (secondary objective), both at a single center.

Mechanically ventilated adult patients with a set tidal volume (primary objective) and providers rotating through the Medical and Neurosciences ICUs (secondary objective).

None.

From 2013 to 2018, the average initial set tidal volume (cc/kg ideal body weight) decreased from 8.99 ± 2.19 to 7.45±1.34 (
< 0.001). The cardiothoracic ICU had the largest change in tidal volume from 11.09 ± 1.96 in 2013 to 7.97 ± 1.03 in 2018 (
< 0.001). Although the majority of tidal volumes across all ICUs were betwolumes over the years, in 2018, over a quarter of mechanically ventilated adult patients were being ventilated with tidal volumes greater than 8 cc/kg. Survey data indicate that despite respondents acknowledging the benefits of lung-protective ventilation, there are barriers to its optimal implementation. Future modifications of the electronic medical record, including a calculator to set tidal volume in cc/kg and the use of default set tidal volumes, may help facilitate the delivery of and adherence to lung-protective ventilation.Involvement of clinical pharmacists in the ICU attenuates costs, avoids adverse drug events, and reduces morbidity and mortality. This survey assessed services and activities of ICU pharmacists.
A 27-question, pretested survey.

1,220 U.S. institutions.

Critical care pharmacists.

Electronic questionnaire of pharmacy services and activities across clinical practice, education, scholarship, and administration.

A total of 401 (response rate of 35.4%) surveys representing 493 ICUs were completed. Median daily ICU census was 12 (interquartile range, 6-20) beds with 1 (interquartile range, 1-1.5) pharmacist full-time equivalent per ICU. Direct clinical ICU pharmacy services were available in 70.8% of ICUs. Pharmacists attended rounds 5 days (interquartile range, 4-5 d) per week with a median patient-to-pharmacist ratio of 17 (interquartile range, 12-26). The typical workweek consisted of 50% (interquartile range, 40-60%) direct ICU patient care, 10% (interquartile range, 8-16%) teaching, 8% (interquartile rartmental policies/guidelines (84-86.8%) and 65.7% conducted some form of scholarship.

ICU pharmacists have diverse and versatile responsibilities and provide several key clinical and nonclinical services. Initiatives to increase the availability of services are warranted.

In recent times, patient care in ICUs has become more complex with technological advances in monitoring, diagnostic testing, and therapeutics; many of these advances have translated into improved patient outcomes. In this increasingly complicated system, local culture and goals for the unit can also be overwhelmed by the impersonal and overarching institutional objectives. Developing "ICU specific principles" is a structured approach to cultivate habits and encourage attitudes that are aligned with the values of the team; this can serve to optimize the work environment and prioritize excellent patient care.End-of-life care and decisions on withdrawal of life-sustaining therapies vary across countries, which may affect the feasibility of future multicenter cardiac arrest trials. In Brazil, withdrawal of life-sustaining therapy is reportedly uncommon, allowing the natural history of postcardiac arrest hypoxic-ischemic brain injury to present itself. We aimed to characterize approaches to neuroprognostication of cardiac arrest survivors among physicians in Brazil.
Cross-sectional study.

Between August 2, 2019, and July 31, 2020, we distributed a web-based survey to physicians practicing in Brazil.

Physicians practicing in Brazil and members of the Brazilian Association of Neurointensive Care, who care for patients resuscitated following cardiac arrest.

Not applicable.

Responses from 185 physicians were obtained. Pupillary reflexes, corneal reflexes, and motor responses were considered critical to prognostication, whereas neuroimaging and electroencephalography were also regarded as important. For patientssicians believed that improving neuroprognostication will impact end-of-life decision-making. Given the tendency to delay prognostic recommendations while using similar neuroprognostic tools, Brazil offers a unique cohort in which to examine the natural history of hypoxic-ischemic brain injury in future studies.
There is significant variability in neuroprognostic approaches to postcardiac arrest patients and timing of prognostic studies among Brazilian physicians, with practices frequently deviating from current guidelines, underscoring a need for greater neuroprognostic accuracy. Nearly all physicians believed that improving neuroprognostication will impact end-of-life decision-making. Given the tendency to delay prognostic recommendations while using similar neuroprognostic tools, Brazil offers a unique cohort in which to examine the natural history of hypoxic-ischemic brain injury in future studies.The presence of spontaneous echo contrast on ultrasonography is a predisposition to increased thromboembolic risk. The purpose of this study was to assess for the prevalence and consequences of spontaneous echo contrast on point-of-care vascular ultrasound in coronavirus disease 2019.
This was a retrospective cohort study of 39 adult patients admitted to the ICU with a confirmed coronavirus disease 2019 diagnosis at a large tertiary-care academic medical center. Patients were included if they had undergone a vascular ultrasound examination during their ICU admission. Overall, 48 venous ultrasound studies among the 39 patients were reviewed in blinded fashion by two reviewers for the presence of venous spontaneous echo contrast, and charts were analyzed for laboratory data and outcomes.

pontaneous echo contrast correlated with serum viscosity (mean values of 2.64, 2.54, and 2.04 cP for dense spontaneous echo contrast, spontaneous echo contrast , and no spontaneous echo contrast, respectively, with a
valustometry - maximum lysis, platelet counts, C-reactive protein, or interleukin-6.

Point-of-care venous ultrasonography is easily performed and reliably interpreted for visualization of spontaneous echo contrast. The presence of spontaneous echo contrast in patients with coronavirus disease 2019 is associated with hyperviscosity and increased rates of thrombotic events and complications.

It has also been associated with acute liver failure.
Retrospective observational study.

Tertiary-care medical ICU.

Thirty-one patients critically ill with hemophagocytic lymphohistiocytosis.

None.

We performed a comprehensive review of critically ill hemophagocytic lymphohistiocytosis patients admitted to a tertiary-care medical ICU from January 2012 to December 2018. Most patients presented with constitutional symptoms and elevated liver enzymes and thrombocytopenia were common upon hospital admission. ICU admission laboratory and clinical variables were used to calculate Acute Physiology and Chronic Health Evaluation II, hemophagocytic syndrome diagnostic score, and model for end-stage liver disease. Mean age of the cohort was 48.1 years, and 45% were male. The mortality rate was 65% at 28 days and 77% at 1 year. About 28-day survivors were younger, hagnostic scores, are more likely to receive hemophagocytic lymphohistiocytosis specific chemotherapy, and are less likely to have organ failure. Hemophagocytic lymphohistiocytosis can be associated with acute liver failure especially when model for end-stage liver disease score is elevated upon admission.
Patients admitted to the ICU with hemophagocytic lymphohistiocytosis have a high mortality. Those who survived had lower Acute Physiology and Chronic Health Evaluation scores, had higher hemophagocytic syndrome diagnostic scores, are more likely to receive hemophagocytic lymphohistiocytosis specific chemotherapy, and are less likely to have organ failure. Hemophagocytic lymphohistiocytosis can be associated with acute liver failure especially when model for end-stage liver disease score is elevated upon admission.
