The apelin receptor generates increasing interest as a potential target across several cardiovascular indications. However, the short half-life of its cognate ligands, the apelin peptides, is a limiting factor for pharmacological use. In this study, we systematically explored each position of apelin-13 to find the best position to cyclize the peptide, with the goal to improve its stability while o...
To determine if there is an association between the single nucleotide polymorphisms (SNPs): rs2046934, rs1126643, rs5918, rs6065, rs4244285; rs4986893 and the occurrence of cardiovascular events (CVE) in patients following coronary artery bypass grafting (CABG) surgery.
Holt-Oram syndrome (HOS) is an autosomal dominant disorder, which is characterized by deformities of upper limbs and congenital heart defects. Alterations of TBX5 gene have been identified to be the leading cause of HOS, while some cases could not be explained by TBX5 mutations. In our study, we preliminarily diagnosed a newborn baby, who had Tetralogy of Fallot, thumb agenesis, facial dysplasia, ...
The term cor pulmonale has traditionally been used as a synonym for right heart failure due to chronic respiratory diseases, although this condition is less frequently seen in the modern era because of the use of long-term oxygen therapy along with aggressive measures directed at optimizing ventilation and gas exchange. The mechanisms by which adaptation or maladaptation of right heart structure a...
Heart failure is a common form of heart disease associated with progressive exercise intolerance and high risk of adverse clinical outcome events. The pathophysiology of chronic systolic heart failure is fundamentally determined by the failure of the circulatory system to deliver oxygen sufficient for metabolic needs, and it is best explained by a complex interplay between intrinsic abnormalities ...
In 1954-1955, the author served as a research fellow in the cardiopulmonary laboratory led by André Cournand at Bellevue Hospital in New York. Cournand was a pulmonary physiologist and a professor of medicine at Columbia University. In his quest to obtain mixed venous blood to calculate pulmonary blood flow, he catheterized the right atrium, right ventricle, and pulmonary artery in patients and a...
To investigate whether Post-Acute Care Inpatient Rehabilitation (PACIR) admission after NICU stay affects the total length of stay (LOS) of very preterm (VPT: ≤30 weeks of gestation) infants.
Obesity and metabolic syndrome are disorders that correlate with the activation of pro-inflammatory pathways and cytokine production, to which Toll like receptors (TLR) contribute. Exercise may act as an anti-inflammatory modulator, but there is no consensus about the role of the TLR in this tuning. The present styudy aims to systematically review the current evidence on exercise-induced TLR regul...
Acute respiratory distress syndrome (ARDS) is defined as hypoxemic respiratory failure with intense pulmonary inflammation, involving hyperactivation of endothelial cells and neutrophils. Given the anti-inflammatory effects of aerobic exercise (AE), this study investigated whether AE performed daily for 5 weeks would inhibit extra-pulmonary LPS-induced ARDS. C57Bl/6 mice were distributed into Cont...
Patients presenting for transcatheter aortic valve replacement are often in acute on chronic heart failure, as indicated by elevated N-terminal pro-B-type natriuretic peptide. Many believe that elevated N-terminal pro-B-type natriuretic peptide is an indication to treat medically, reserving surgery until the patient is medically optimized.
The primary objective was to investigate the long-term survival of patients who underwent single-vessel coronary revascularization with minimally invasive direct coronary artery bypass surgery with or without hybrid revascularization. The secondary outcome measures were repeat revascularization either by coronary artery bypass grafting or by percutaneous coronary intervention and the incidence of ...
Previous studies have shown that women carry a higher risk of morbidity and mortality after coronary artery bypass surgery. We investigated sex differences in risk factors and outcomes in our patients undergoing robotic beating heart connector totally endoscopic coronary artery bypass.
Postoperative prescribing following acute care surgery must be optimized to limit excess opioids in circulation as misuse and diversion are frequently preceded by a prescription for acute pain. This study aimed to identify patient characteristics associated with higher opioid prescribing following laparoscopic cholecystectomy (LC).
Examining tracheal microbiota before, during, and after acute respiratory infection (ARI) in patients with a tracheostomy demonstrated large baseline intra-patient microbiota variability and a significant bloom of Haemophilus and Moraxella on day 1 of ARI symptoms. The tracheal microbiota community composition changed significantly from baseline to 1 month after ARI.
Myocardial infarction (MI) causes significant loss of cardiomyocytes, myocardial tissue damage, and impairment of myocardial function. The inability of cardiomyocytes to proliferate prevents the heart from self-regeneration. The treatment for advanced heart failure following an MI is heart transplantation despite the limited availability of the organs. Thus, stem-cell-based cardiac therapies could...
TGFβ superfamily includes the transforming growth factor βs (TGFβs), bone morphogenetic proteins (BMPs), growth and differentiation factors (GDFs) and Activin/Inhibin families of ligands. Among the 33 members of TGFβ superfamily ligands, many act on multiple types of cells within the heart, including cardiomyocytes, cardiac fibroblasts/myofibroblasts, coronary endothelial cells, smooth muscle ...
High blood pressure (HBP) is a major cardiovascular disease (CVD) risk factor. Clinical trials including Dietary Approaches to Stop Hypertension (DASH) have demonstrated beneficial effects of dairy consumption on risks of HBP and CVD. Yogurt, a fermented dairy product, may independently be related to CVD risk.
To implement secondary care electronic record linkage for patients hospitalised with suspected or known acute coronary syndrome (ACS) in a complex regional healthcare system and evaluate this e-Registry in terms of patterns of service delivery and 1-year outcomes.
Half of all heart failure patients have preserved ejection fraction (HFpEF). Comorbidities associated with and contributing to HFpEF include obesity, diabetes and hypertension. Still, the underlying pathophysiological mechanisms of HFpEF are unknown. A preliminary consensus proposes that the multi-morbidity triggers a state of systemic, chronic low-grade inflammation and microvascular dysfunction,...
Three data sources are generally used in monitoring health on the population level. Health interview surveys (HISs) are based on participants' self-report. Health examination surveys (HESs) yield more objective data, and also persons who are unaware of their elevated risks can be detected. Medical records (MRs) and other administrative registers also provide objective data, but their availability,...
Understanding disease seasonality is important for improving clinical practice, hospital resource utilization and community-based preventive care. However, no studies have investigated the seasonality of acute kidney injury (AKI).
The molecular mechanism of brain arteriovenous malformation (BAVM) is largely unknown. Intracranial venous hypertension (VH) may enhance focal angiogenesis and promote BAVM development and progression. A rat VH model effectively simulates the hemodynamic microenvironment of this disease.
Given the high prevalence of hypertension in adolescents, it is important to investigate alternatives for estimating the magnitude of the disease. Our objective was to investigate the accuracy of self-reported hypertension. The study assessed participants of the Study of Cardiovascular Risk in Adolescents (ERICA). The following were calculated: sensitivity, specificity, positive predictive value (...
