Introduction Moderate mitral regurgitation (MR) of ischemic etiology has been associated with worse outcomes after coronary artery bypass grafting (CABG). Studies comparing concomitant mitral valve replacement/repair (MVR/Re) with CABG and standalone CABG have reported conflicting results. We performed a systematic review and meta-analysis of the published literature. Patients and Methods We searched using PubMed, Cochrane, EMBASE, CINAHL, and Google scholar databases from January 1960 to June 2016 for clinical trials comparing CABG to CABG + MVR/Re for moderate MR...

BACKGROUND: Effective regurgitant orifice area (EROA), calculated from the vena contracta width (VCW) as the narrowest portion of the proximal regurgitant jet, might be used to estimate severity of mitral regurgitation. However, this simplified assumption only holds when the EROA is circular, which might not be true in dogs with myxomatous mitral valve disease (MMVD). HYPOTHESIS: Effective regurgitant orifice area in dogs with MMVD is noncircular, and using color Doppler real-time 3-dimensional (RT3D) echocardiography, measured EROA in the en face view will be significantly different from calculated EROA...

Protein disulfide isomerase (PDI) plays a major role in platelet aggregation and its inhibitors have emerged as novel antithrombotic drugs. In previous work, we designed a peptide based on PDI redox motif (CGHC) that inhibited both PDI reductase activity and PDI-modulated superoxide generation by neutrophil Nox2. Thus, we hypothesized this peptide would also inhibit platelet aggregation by association to surface PDI. Three peptides were used: CxxC, containing the PDI redox motif; Scr, presenting a scrambled sequence of the same residues and AxxA, with cysteines replaced by alanine...

Off the shelf scaffolds for replacing ultra-small diameter vascular grafts are valuable for reconstruction of diseased or damaged vessels. The limitations for such grafts include optimal handling with ready availability of varied lengths of grafts, graft patency with the ability to replace the function of active cellular mechanisms and adequate mechanical properties to maintain physicochemical function. We used a well-established, solvent casting method for potential tissue replacement scaffold fabrication with incorporated bioactive molecules, which we have previously explored to confer haemocompatibility...

Antegrade balloon aortic valvuloplasty (BAV) may be more effective than retrograde BAV. However, early restenosis is found inconstantly within three months after BAV. To evaluate the factor of ER after intracardiac echocardiogram (ICE) guided Antegrade BAV, fifty patients with severe aortic stenosis (AS) underwent BAV procedures with ICE. ER was defined as mean aortic valve pressure gradient (PG) >40 mmHg. During one-year follow-up period, 6 patients died and 2 patients underwent aortic valve replacement...

Endovascular repair of abdominal aortic aneurysms has widely replaced the open surgical repair due to its minimal invasive nature and the accompanying lower perioperative mortality and morbidity. During the past two decades, certain improvements and developments have provided a wide variety of endograft structural designs and geometric patterns, enabling the physician to approach a more patient-specific treatment of AAA. This review presents the currently available aortic endografts and describes the clinical, technical and mechanical characteristics of them...

BACKGROUND: The Affordable Care Act of 2010 advanced the economic model of bundled payments for total joint arthroplasty (TJA), in which hospitals will be financially responsible for readmissions, typically at 90 days after surgery. However, little is known about the financial burden of readmissions and what patient, clinical, and hospital factors drive readmission costs. QUESTIONS/PURPOSES: (1) What is the incidence, payer mix, and demographics of THA and TKA readmissions in the United States? (2) What patient, clinical, and hospital factors are associated with the cost of 30- and 90-day readmissions after primary THA and TKA? (3) Are there any differences in the economic burden of THA and TKA readmissions between payers? (4) What types of THA and TKA readmissions are most costly to the US hospital system? METHODS: The recently developed Nationwide Readmissions Database from the Healthcare Cost and Utilization Project (2006 hospitals from 21 states) was used to identify 719,394 primary TJAs and 62,493 90-day readmissions in the first 9 months of 2013 based on International Classification of Diseases, 9th Revision, Clinical Modification codes...

Both mammals and adult humans possess classic brown adipocytes and beige adipocytes, and the amount and activity of these adipocytes are considered key factors in combating obesity and its associated metabolic diseases. Uncoupling protein 1 (Ucp1) is the functional marker of both brown and beige adipocytes. To facilitate a reliable, easy, and sensitive measurement of Ucp1 expression both in vivo and in vitro, we generated a Ucp1-2A-luciferase knock-in mouse by deleting the stop codon for the mouse Ucp1 gene and replacing it with a 2A peptide...

OBJECTIVES: Both kaolin- and Celite-activated clotting times (ACT) are used to guide anticoagulation during cardiopulmonary bypass. It is unknown whether these methods lead to similar management procedures for anticoagulation in patients and are thus interchangeable in terms of bias, precision and variability. METHODS: We randomized 97 patients undergoing coronary artery bypass grafting or aortic valve replacement to either kaolin- or Celite-guided anticoagulation...

OBJECTIVES: Considering the chronic and progressive nature of aortic dissection, operative planning must anticipate the need for later interventions. We have increasingly used a modified version of the frozen elephant trunk repair operation to treat these patients. We review the indications, considerations for planning, and important operative details for performing frozen elephant trunk repair for chronic aortic dissection. METHODS: Frozen elephant trunk repair is performed using selective antegrade brain perfusion, direct placement of commercially available stent grafts with suture fixation in the aortic arch, and proximal aortic replacement...

OBJECTIVES: In patients with acute aortic dissection involving the arch and the descending aorta (AADA DeBakey type I), performing a total aortic arch replacement with the frozen elephant trunk (FET) procedure for supposedly better long-term results is still controversial. METHODS: From February 2004 to April 2016, 94 patients with AADA DeBakey type I had an FET procedure (80% men, age 58 ± 12 years). During the early period (Group 1, 2004-10), the FET technique was performed using non-branched grafts...

SummaryThe development of new devices to improve treatment and to explore new indications that have not yet been adequately addressed is a natural consequence of the clinical demand for solutions to as yet unmet needs. The frozen elephant trunk technique was one of the major steps within the last 15 years to improve on existing treatments as well as to explore new indications. The goal of this article is to provide technical details about advances in implantation techniques for the treatment of acute and chronic thoracic aortic pathological conditions...

SummaryAortic arch surgery requires complex patient management beyond the manual replacement of the diseased vessel. These procedures include (i) a thorough and pathologically adjusted preoperative evaluation, (ii) initiation and control of cardiopulmonary bypass, (iii) cerebral protection strategies and (iv) techniques to protect the abdominal end organs during prolonged operations. Due to the complexity of aortic arch procedures, multimodal real-time surveillance is required during all stages of the operation...

Genomic prediction is a statistical method to predict phenotypes of polygenic traits using high throughput genomic data. Most diseases and behaviors in human and animals are polygenic traits. The majority of agronomic traits in crops are also polygenic. Accurate prediction of these traits can help medical professionals diagnose acute diseases and breeders to increase food products, and therefore, significantly contribute to human health and global food security. The best linear unbiased prediction (BLUP) is an important tool to analyze high throughput genomic data for prediction...

Fungal nonribosomal peptide synthetases (NRPSs) are megasynthetases that produce cyclic and acyclic peptides. In Aspergillus nidulans, the NRPS ivoA (AN10576) has been associated with the biosynthesis of grey-brown conidiophore pigments. Another gene, ivoB (AN0231), has been demonstrated to be an N-acetyl-6-hydroxytryptophan oxidase that putatively acts downstream of IvoA. A third gene, ivoC, has also been predicted to be involved in pigment biosynthesis based on publicly available genomic and transcriptomic information...
