80 (95% confidence interval (CI) 0.75-0.84) vs. AUC 0.87 (95% CI 0.86-0.89); P = 0.004]. Time to discharge from the ED was significantly longer in patients with prior CABG [359 (215-525) min vs. 300 (192-435) min; P &lt; 0.001]. Key findings were confirmed in a large independent external validation cohort (n = 13653).<br />Patients with prior CABG presenting with suspected AMI have a high prevalence of AMI and unstable angina and lower diagnostic accuracy of CPCs and the ECG, possibly justifying liberal use of early coronary angiography in these vulnerable patients.<br />Number NCT00470587.<br />Number NCT00470587.<br />Coronary microvascular obstruction (MVO) occurs frequently in patients with ST-elevation myocardial infarction (STEMI) after percutaneous coronary intervention (PCI). However, mechanisms are multiple and not yet fully understood. Perilipin 2 (PLIN2) is involved in lipid metabolism of macrophages resident in atherosclerotic plaques, along with a role in enhancing plaque inflammation. We studied the association between PLIN2 and MVO in STEMI patients undergoing primary PCI, and we assessed the role of PLIN2 to predict major adverse cardiovascular events (MACEs).<br />STEMI patients undergoing primary PCI were enrolled. PLIN2 was evaluated in peripheral blood monocytes; MVO was assessed using coronary angiogram. MACEs, as a composite of cardiac death, non-fatal myocardial infarction, re-admission for heart failure, and target vessel revascularization were investigated at follow-up. Among 100 STEMI patients, 33 (33.0%) had MVO. Patients with MVO had higher levels of PLIN2 (1.03 ± 0.28 vs. 0.90 ± 0.16, P = 0.019). ndently associated with MVO and was an independent predictor of MACEs at follow-up, suggesting to further explore PLIN2 as a target for future cardioprotection therapies.Base editors are capable of installing precise genomic alterations without creating double-strand DNA breaks. In this study, we targeted critical motifs regulating γ-globin reactivation with base editors delivered via HDAd5/35++ vectors. Through optimized design, we successfully produced a panel of cytidine and adenine base editor (ABE) vectors targeting the erythroid BCL11A enhancer or recreating naturally occurring hereditary persistence of fetal hemoglobin (HPFH) mutations in the HBG1/2 promoter. All 5 tested vectors efficiently installed target base conversion and led to γ-globin reactivation in human erythroid progenitor cells. We observed ~23% γ-globin protein production over β-globin, when using an ABE vector (HDAd-ABE-sgHBG-2) specific to the -113A&gt;G HPFH mutation. In a β-YAC mouse model, in vivo hematopoietic progenitor/stem cell (HSPC) transduction with HDAd-ABE-sgHBG-2 followed by in vivo selection resulted in &gt;40% γ-globin+ erythrocytes in the peripheral blood. This result corresponded to 21% γ-globin production over human β-globin. The average -113A&gt;G conversion in total bone marrow cells was 20%. No alterations in hematological parameters, erythropoiesis, and bone marrow cellular composition were observed after treatment. No detectable editing was found at top-scoring, off-target genomic sites. Bone marrow lineage-negative cells from primary mice were capable of reconstituting secondary transplant-recipient mice with stable γ-globin expression. Importantly, the advantage of base editing over CRISPR/Cas9 was reflected by the markedly lower rates of intergenic HBG1/2 deletion and the absence of detectable toxicity in human CD34+ cells. Our observations suggest that HDAd-vectorized base editors represent a promising strategy for precise in vivo genome engineering for the treatment of β-hemoglobinopathies.<br />Troponin-based algorithms are made to identify myocardial infarctions (MIs) but adding either standard acute coronary syndrome (ACS) risk criteria or a clinical risk score may identify more patients eligible for early discharge and patients in need of urgent revascularization.<br />Post-hoc analysis of the WESTCOR study including 932 patients (mean 63 years, 61% male) with suspected NSTE-ACS. Serum samples were collected at 0, 3, and 8-12 h and high-sensitivity cTnT (Roche Diagnostics) and cTnI (Abbott Diagnostics) were analysed. The primary endpoint was MI, all-cause mortality, and unplanned revascularizations within 30 days. Secondary endpoint was non-ST-elevation myocardial infarction (NSTEMI) during index hospitalization. Two combinations were compared troponin-based algorithms (ESC 0/3 h and the High-STEACS algorithm) and either ACS risk criteria recommended in the ESC guidelines, or one of eleven clinical risk scores, HEART, mHEART, CARE, GRACE, T-MACS, sT-MACS, TIMI, EDACS, sEDACS, Goldman, and Geleijnse-Sanchis. The prevalence of primary events was 21%. Patients ruled out for NSTEMI and regarded low risk of ACS according to ESC guidelines had 3.8-4.9% risk of an event, primarily unplanned revascularizations. Using HEART score instead of ACS risk criteria reduced the number of events to 2.2-2.7%, with maintained efficacy. The secondary endpoint was met by 13%. The troponin-based algorithms without evaluation of ACS risk missed three-index NSTEMIs with a negative predictive value (NPV) of 99.5% and 99.6%.<br />Combining ESC 0/3 h or the High-STEACS algorithm with standardized clinical risk scores instead of ACS risk criteria halved the prevalence of rule-out patients in need of revascularization, with maintained efficacy.<br />Combining ESC 0/3 h or the High-STEACS algorithm with standardized clinical risk scores instead of ACS risk criteria halved the prevalence of rule-out patients in need of revascularization, with maintained efficacy.<br />Dexmedetomidine is one of the sedative agents recommended by the Society of Critical Care Medicine as a preferred option over benzodiazepines in critically ill, mechanically ventilated patients. Little data exists describing sedation in the cardiac intensive care unit (CICU). The purpose of this study was to determine the prevalence of adverse events in CICU patients treated with dexmedetomidine.<br />This was a retrospective cohort analysis of patients &gt;18 years old admitted to the University of Michigan CICU from June 2014 to October 2019 who received dexmedetomidine therapy.

Secondary outcomes included individual components of the primary outcome. Patients that experienced adverse events were compared to those that did not experience adverse events to identify risk factors for adverse events. A total of 197 patients were included. There were 116 adverse events in 106 patients.
