Evaluation of Aliphatic Alcohols for CO2 Capture Using the Characteristic Carbonate Frequency.

Control over CO2 capture and utilization are important scientific and technological challenges. Although a variety of amine absorbents are used for capture, releasing the captured CO2 is often difficult and limits their recyclability. Therefore, it is crucial to control the strength of the CO2 bond with the absorbent.

Photoinduced Carbon Dioxide Release via a Metastable Photoacid in a Nonaqueous Environment.

Capturing carbon dioxide (CO) from the atmosphere is a scientific and technological challenge. CO can be captured by forming carbamate bonds with amines, most notably monoethanolamine (MEA). Regenerating MEA by releasing captured CO requires that the carbamate solution be heated.

Clinical pharmacokinetics and pharmacodynamics of empagliflozin in patients with heart failure.

Aims: The aim of this work is to compare empagliflozin systemic exposure between patients with heart failure (HF) and patients with type 2 diabetes (T2D).

Methods: Analysis of covariance (ANCOVA) compared steady state trough concentrations of empagliflozin 10 mg in EMPEROR-reduced (patients with HF with reduced ejection fraction [HFrEF]) and EMPA-REG OUTCOME (patients with T2D at high cardiovascular risk) after adjusting for eGFR and body weight.

Results: The difference in geometric Mean (gMean) empagliflozin steady state trough concentration of 10 mg empagliflozin between EMPEROR-reduced and EMPA-REG OUTCOME was 1.

Inferring the Energetics of CO-Aniline Adduct Formation from Vibrational Spectroscopy.

Control of atmospheric CO is an important contemporary scientific and engineering challenge. Toward this goal, the reaction of CO with amines to form carbamate bonds is an established method for CO capture. However, controllable reversal of this reaction remains difficult and requires tuning the energetics of the carbamate bond.

Clinical decision support to Optimize Care of patients with Atrial Fibrillation or flutter in the Emergency department: protocol of a stepped-wedge cluster randomized pragmatic trial (O'CAFÉ trial).

Background: Management of adults with atrial fibrillation (AF) or atrial flutter in the emergency department (ED) includes rate reduction, cardioversion, and stroke prevention. Different approaches to these components of care may lead to variation in frequency of hospitalization and stroke prevention actions, with significant implications for patient experience, cost of care, and risk of complications. Standardization using evidence-based recommendations could reduce variation in management, preventable hospitalizations, and stroke risk.

Aggregation of Charge Acceptors on Nanocrystal Surfaces Alters Rates of Photoinduced Electron Transfer.

Semiconductor nanocrystals (NCs) interfaced with molecular ligands that function as charge and energy acceptors are an emerging platform for the design of light-harvesting, photon-upconverting, and photocatalytic materials. However, NC systems explored for these applications often feature high concentrations of bound acceptor ligands, which can lead to ligand-ligand interactions that may alter each system's ability to undergo charge and energy transfer. Here, we demonstrate that aggregation of acceptor ligands impacts the rate of photoinduced NC-to-ligand charge transfer between lead(II) sulfide (PbS) NCs and perylenediimide (PDI) electron acceptors.

Controlling Symmetry Breaking Charge Transfer in BODIPY Pairs.

Symmetry breaking charge transfer (SBCT) is a process in which a pair of identical chromophores absorb a photon and use its energy to transfer an electron from one chromophore to the other, breaking the symmetry of the chromophore pair. This excited state phenomenon is observed in photosynthetic organisms where it enables efficient formation of separated charges that ultimately catalyze biosynthesis. SBCT has also been proposed as a means for developing photovoltaics and photocatalytic systems that operate with minimal energy loss.

Point-of-care testing for tetanus immunity: a systematic review and meta-analysis.

Background: The current standard of care for tetanus prophylaxis management in patients with open wounds likely results in overtreatment and unnecessary costs. Point-of-care immunochromatographic tests, known as Tetanus Quick Sticks (TQS), have been developed to qualitatively measure tetanus immunoglobulin levels. Multiple studies advocate their use in EDs.

Graded Coronary Risk Stratification for Emergency Department Patients With Chest Pain: A Controlled Cohort Study.

Background Resource utilization among emergency department (ED) patients with possible coronary chest pain is highly variable. Methods and Results Controlled cohort study amongst 21 EDs of an integrated healthcare system examining the implementation of a graded coronary risk stratification algorithm (RISTRA-ACS [risk stratification for acute coronary syndrome]). Thirteen EDs had access to RISTRA-ACS within the electronic health record (RISTRA sites) beginning in month 24 of a 48-month study period (January 2016 to December 2019); the remaining 8 EDs served as contemporaneous controls.

Prognostic Importance of NT-proBNP and Effect of Empagliflozin in the EMPEROR-Reduced Trial.

Background: The relationship between the benefits of empagliflozin in heart failure with reduced ejection fraction (HFrEF) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) has not been reported.

Objectives: The authors sought to evaluate the relationship between NT-proBNP and empagliflozin effects in EMPEROR-Reduced (Empagliflozin Outcome Trial in Patients With Chronic Heart Failure With Reduced Ejection Fraction).

Methods: Patients with HFrEF were randomly assigned to placebo or empagliflozin 10 mg daily.

Clinical characteristics of COVID-19 patients evaluated in the emergency department: A retrospective cohort study of 801 cases.

Background: Coronavirus disease 2019 (COVID-19), the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has extracted devastating tolls. Despite its pervasiveness, robust information on disease characteristics in the emergency department (ED) and how that information predicts clinical course remain limited.

Methods: We conducted a retrospective cohort study of the first ED visit from SARS-CoV-2-positive patients in our health system, from February 21, 2020 to April 5, 2020.

Concentration-dependent clinical and prognostic importance of high-sensitivity cardiac troponin T in heart failure and a reduced ejection fraction and the influence of empagliflozin: the EMPEROR-Reduced trial.

Aims: Circulating troponin is an important measure of risk in patients with heart failure, but it has not been used to determine if disease severity influences the responses to drug treatments in randomized controlled trials.

Methods And Results: In the EMPEROR-Reduced trial, patients with class II-IV heart failure and a reduced ejection fraction were randomly assigned to placebo or empagliflozin 10 mg daily and followed for the occurrence of serious heart failure and renal events. High-sensitivity cardiac troponin T (hs-cTnT) was measured in 3636 patients (>97%) at baseline, and patients were divided into four groups based on the degree of troponin elevation.

Prospective Validation and Comparative Analysis of Coronary Risk Stratification Strategies Among Emergency Department Patients With Chest Pain.

Background Coronary risk stratification is recommended for emergency department patients with chest pain. Many protocols are designed as "rule-out" binary classification strategies, while others use graded-risk stratification. The comparative performance of competing approaches at varying levels of risk tolerance has not been widely reported.
