: Fibrotic cardiac muscle exhibits high stiffness and low compliance which are major risk factors of heart failure. Although heat shock transcription factor 1 (HSF1) was identified as an intrinsic cardioprotective factor, the role that HSF1 plays in cardiac fibrosis remains unclear. Our study aims to investigate the role of HSF1 in pressure overload-induced cardiac fibrosis and the underlying mechanism. HSF1 phosphorylation was significantly downregulated in transverse aortic constriction (TAC)-treated mouse hearts and mechanically stretched cardiac fibroblasts (cFBs)...

Portopulmonary hypertension (POPH) is a poorly understood complication of liver disease associated with significant morbidity and mortality. We sought to identify novel biomarkers of POPH disease presence and severity. We performed a prospective, multicenter, case-control study involving patients with liver disease undergoing right heart catheterization. POPH cases were defined as a mean pulmonary arterial pressure (mPAP) ≥25 mmHg and pulmonary vascular resistance (PVR) >240 dynes˙s˙cm(-5). Plasma samples were collected from the systemic and pulmonary circulation, and antibody microarray was used to identify biomarkers...

BACKGROUND: Effusive-constrictive pericarditis (ECP) is traditionally diagnosed by using the expensive and invasive technique of direct pressure measurements in the pericardial space and the right atrium. The aim of this study was to assess the diagnostic role of echocardiography in tuberculous ECP. METHODS: Intrapericardial and right atrial pressures were measured pre- and post-pericardiocentesis, and right ventricular and left ventricular pressures were measured post-pericardiocentesis in patients with tuberculous pericardial effusions...

BACKGROUND: Surgical site infections (SSI) remain a major source of morbidity and cost after resection of intra-abdominal malignancies. Negative pressure wound therapy (NPWT) has been reported to significantly reduce SSI when applied to the closed laparotomy incision. This paper reports results of a randomized clinical trial examining the effect of NPWT on SSI rates in surgical oncology patients with increased risk for infectious complications. STUDY DESIGN: From 2012-2016, 265 patients underwent open resection of intra-abdominal neoplasms stratified into three groups: gastrointestinal (n=57), pancreas (n=73), and peritoneal surface malignancy (n=135)...

Impaired sulfatide catabolism is the primary biochemical insult in patients with the inherited neurodegenerative disease, metachromatic leukodystrophy (MLD), and sulfatide elevation in body fluids is useful in the diagnostic setting. Here we used mass spectrometry to quantify fourteen species of sulfatide, in addition to the deacetylated derivative, lyso-sulfatide, using high pressure liquid chromatography-electrospray ionisation-tandem mass spectrometry in both positive and negative ion mode. A single phase extraction of 0...

Ciprofloxacin is an important antibacterial drug targeting Type II topoisomerases, highly active against Gram-negatives including Escherichia coli The evolution of resistance to ciprofloxacin in E. coli always requires multiple genetic changes, usually including mutations affecting two different drug target genes, gyrA and parC Resistant mutants selected in vitro or in vivo can have many different mutations in target genes and efflux regulator genes that contribute to resistance. Among resistant clinical isolates the genotype, gyrA S83L D87N, parC S80I is significantly overrepresented suggesting that it has a selective advantage...

In 2007 the International Diabetes Federation (IDF) proposed single blood pressure (BP) cutpoints (systolic: ≥130 mm Hg and diastolic: ≥85 mm Hg) for the diagnosis of high blood pressure (HBP) in adolescents. Before this proposal, HBP had been defined as BP at or above the 95th percentile for age, sex, and height percentile (reference standard). In this study, we evaluated the risk for misclassification when using the IDF single-cutpoints criteria. We first applied the IDF criteria to a reconstructed population with the same age, sex, and height distribution as the population used to develop the reference standard...

Adrian A Matioc
This second installment of the history of basic airway management covers the early-artisanal-years of anesthesia from 1846 to 1904. Anesthesia was invented and practiced as a supporting specialty in the context of great surgical and medical advances. The current-day anesthesia provider tends to equate the history of airway management with the history of intubation, but for the first 58 yr after the introduction of ether anesthesia, airway management was provided by basic airway techniques with or without the use of a face mask...

Questions remain regarding the potential negative effects of dietary high protein (HP) on kidney health, particularly in the context of obesity in which the risk for renal disease is already increased. To examine whether some of the variability in HP effects on kidney health may be due to source of protein, obese fa/fa Zucker rats were given HP (35% of energy from protein) diets containing either casein, soy protein, or a mixed source of animal and plant proteins for 12 weeks. Control lean and obese rats were given diets containing casein at normal protein (15% of energy from protein) levels...

BACKGROUND: Postoperative, iatrogenic or spontaneous upper gastrointestinal defects result in significant morbidity and mortality of the patients. In the last few years, endoscopic vacuum therapy (EVT) has been recognized as a new promising method for repairing upper gastrointestinal defects of different etiology. However, probably due to insufficient data and no commercially available system for EVT of the upper gastrointestinal tract, until the end of 2014, covering of esophageal defects with self-expanding metal stents (SEMS) were still the mainstay of endoscopic therapy...

The early arterial dysfunction linked with obesity and a sedentary lifestyle heightens the likelihood of suffering from future cardiovascular events. Whole-body vibration training (WBVT) may improve systemic arterial stiffness (brachial-ankle pulse wave velocity (baPWV)) and muscle strength in pre- and post-menopausal women. However, the effectiveness of WBVT to impact the arterial segments included in baPWV is unknown. The aim of this study was to investigate the effects of WBVT on aortic and leg arterial stiffness in young sedentary overweight/obese women...

William E Hughes, Darren P Casey
BACKGROUND: Aortic wave reflection (augmentation index; AIx) decreases during orthostatic challenges despite increased peripheral resistance, which is thought to be due to venous pooling. The purpose of this study was to examine if the decrease in AIx during an orthostatic challenge is due to venous pooling alone or body position manipulation. METHODS: Twenty-three young, healthy adults (11F/12M) participated in 3 separate orthostatic challenges (5 minutes each); 60° head-up tilt (HUT), 60° HUT with bilateral rhythmic blood pressure (BP) cuff inflation on calves (75 mm Hg) to minimize venous pooling, and lower body negative pressure (LBNP; -30 mm Hg) for venous pooling independent of body position...

The clinical value of ischemic conditioning during percutaneous coronary intervention (PCI) and mode of administration is controversial. Our aim was to assess the long-term effect of remote ischemic postconditioning among patients undergoing PCI. We randomized 360 patients undergoing PCI who presented with a negative troponin T at baseline into 3 groups: 2 groups received remote ischemic postconditioning (with ischemia applied to the arm in 1 group and to the thigh in the other group), and the third group acted as a control group...
