According to the latest European Society of Cardiology Guidelines for the diagnosis and management of chronic coronary syndromes, patients who suffered an acute coronary syndrome fall into a chronic stable phase after 1 year. In these patients, the estimated 10-year risk for recurrent cardiovascular events varies considerably. We applied the SMART (Second Manifestations of Arterial Disease) risk score in 281 patients 1 year after an acute coronary syndrome to estimate the 10-year risk for recurrent cardiovascular events (subsequent nonfatal myocardial infarction, nonfatal stroke, or cardiovascular death). We assessed the distribution of the estimated risk and the potential risk reduction that might be achieved with optimal guideline-directed management of modifiable risk factors (systolic blood pressure, low-density lipoprotein cholesterol, smoking, and body mass index). In our cohort, the median SMART score was 16.1% (interquartile range [IQR] 9.7 to 27.3), particularly increased in patients with older age, diabetes, polyvascular disease or chronic kidney disease (median 28.6%, IQR 20.8 to 52.9; 23.8%, 4.8 to 41.6; 29.4%, 18.8 to 49.7; 53.8%, 26.5 to 71.6, respectively). If all modifiable risk factors met guideline-recommended targets, the median SMART risk score would be 9.6% (IQR 6.3 to 20.9), with 51% of the patients at a 10-year risk 20% 10-year risk, even with optimal risk factor management, clearly underlining that residual risk is an unmet clinical challenge.The problem of stabilizing dynamic systems with unknown or uncertain equilibrium states is studied. Derivative control schemes are proposed for both state and output feedback for the local stabilization at the true equilibrium states. The case where norm-bounded uncertainties are present in the system model is considered to derive robust stability conditions in linear matrix inequality form. The proposed control solutions drive the closed-loop system exponentially to its equilibrium states as shown via simulation on the chaotic Rössler and Lorenz attractors, when the equilibrium states are unknown and model uncertainties are present. A practical example involving a magnetic levitation system, in which two disks are to be levitated at an unknown magnetic equilibrium, demonstrates the effectiveness of the output derivative feedback controller.This paper aims to compare two strategies for damping low-frequency electromechanical oscillations in multi-machine power systems through Static Synchronous Compensators (STATCOM) with a multi-band controller. STATCOM is represented by a controllable voltage source behind an impedance and the multi-band controller acts as a power oscillation damper that modulates parameters of the voltage source in the transient period. In the first strategy, the multi-band controller acts on the voltage-control loop through the voltage modulation. In the second one, the controller acts on the real power-control loop to modulate the phase angle of the voltage source. The coordinated design of multi-band controllers and power systems stabilizers is performed through an optimization approach taking into account several operation conditions.
Effects of cardiovascular (CV) risk factors on the diameter of the thoracic aorta have not been fully studied. This study examined the associations between CV risk factors and diameter of thoracic aorta.

Study population comprised of 1273 asymptomatic adults aged ≥18 years from Central Appalachia region of the United States who participated in a coronary artery screening between January 2014 and December 2016. Descriptive statistics and multiple linear regression analyses were performed to examine associations between multiple CV risk factors and diameters of the thoracic aorta.

Mean (±SD) age of participants was 57.9±9.7 years; that of body mass index (BMI) was 29.4±5.9. The mean aortic sinus, ascending aorta, and descending aorta diameter were 34.1±4.4mm, 33.8±4.4mm, and 26.0±3.6mm, respectively. Increasing age, being male, and having a higher BMI were associated with wider aortic sinus, ascending aorta, and descending aorta diameters. Hypertension (p<0.05) and obesity (p<0.0001) were significantly associated with wider diameter for all measured aortic diameters. Participants with diabetes had wider descending aorta compared to those without (26.6±3.9mm vs. 25.9±3.5mm, P=0.012). Participants who had ever smoked a cigarette had significantly wider descending aorta diameter compared to never smokers (26.3±3.6 mm vs. 25.9±3.5 mm, p=0.031).

The study results suggest that decreasing BMI and management of CV risk factors such as hypertension and modifying behavioral risk factors such as smoking are likely to be emphasized in order to decrease the rate of aortic dilatation and subsequent aortic dissection, if aortic dilatation is detected during a CT scan.

Patients undergoing esophagectomy often receive jejunostomy tubes (j-tubes) for nutritional supplementation. read more We hypothesized that j-tubes are associated with increased post-esophagectomy readmissions.

We identified esophagectomies for malignancy with (EWJ) or without (EWOJ) j-tubes using the 2010-2015 Nationwide Readmissions Database. Outcomes include readmission, inpatient mortality, and complications. Outcomes were compared before and after propensity score matching (PSM).

Of 22,429 patients undergoing esophagectomy, 16,829 (75.0%) received j-tubes. Patients were similar in age and gender but EWJ were more likely to receive chemotherapy (24.2% vs. 15.1%, p<0.01). EWJ was associated with decreased 180-day inpatient mortality (HR 0.72 [0.52-0.99]) but not with higher readmissions at 30- (15.2% vs. 14.0%, p=0.16; HR 0.9 [0.77-1.05]) or 180 days (25.2% vs. 24.3%, p=0.37; HR 0.94 [0.79-1.10]) or increased complications (p=0.37). These results were confirmed in the PSM cohort.

J-tubes placed in the setting of esophagectomy do not increase inpatient readmissions or mortality.
