BACKGROUND: Interleukin 6 (IL-6) is a predictive factor of poor prognosis in patients with acute respiratory distress syndrome (ARDS). However, its acute pulmonary hemodynamic effects and role in lung injury have not been investigated in a clinically relevant murine model of ARDS. METHODS: We used adult C57Bl6 wild-type (WT) and IL-6 knock-out (IL-6KO) mice. The animals received intravenous recombinant human IL-6 (rHuIL-6) or vehicle followed by intratracheal lipopolysaccharide (LPS) or saline before undergoing low tidal volume mechanical ventilation (MV) for 5 h...

In this review on respiratory assistance, we aim to discuss the following recent advances: the optimization and customization of mechanical ventilation, the use of high-frequency oscillatory ventilation, and the role of noninvasive ventilation. The prevention of ventilator-induced lung injury and diaphragmatic dysfunction is now a key aspect in the management of mechanical ventilation, since these complications may lead to higher mortality and prolonged length of stay in intensive care units. Different physiological measurements, such as esophageal pressure, electrical activity of the diaphragm, and volumetric capnography, may be useful objective tools to help guide ventilator assistance...

Increased inflammation arising from an abnormal immune response can damage healthy tissue and lead to disease progression. An important example of this is the accumulation of inflammatory mediators in the kidney, which can subsequently lead to hypertension and renal injury. The origin of this inflammation may involve neuro-immune interactions. For example, the novel vagus nerve-to-spleen mechanism known as the "cholinergic anti-inflammatory pathway" controls inflammation upon stimulation. However, if this pathway is dysfunctional, inflammation becomes less regulated and chronic inflammatory diseases such as hypertension may develop...

Traumatic brain injury (TBI) is the leading cause of injury-related death in children, with boys and children under 4 years having particularly poor outcomes. Activation of ATP- and calcium-sensitive (KATP and KCa ) channels produces cerebrovasodilation and contributes to autoregulation, both of which are impaired after TBI, contributing to poor outcomes. Upregulation of the c-Jun-terminal kinase (JNK) isoform of mitogen-activated protein kinase produces K channel function impairment after CNS injury. Vasoactive agents can be used to normalize cerebral perfusion pressure...

Simvastatin is a hypolipidemic drug that inhibits hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase to control elevated cholesterol, or hypercholesterolemia. Previous studies have shown that simvastatin may attenuate inflammation in ischemia-reperfusion injury and sepsis. Herein, we hypothesized that simvastatin may prevent rats from lipopolysaccharide (LPS)-induced septic shock. In our study, rats were divided into a saline group, an LPS group and an LPS plus simvastatin group. Male Sprague-Dawley (SD) rats were pretreated with simvastatin (1 mg/kg) for 30 min before the addition of LPS (8 mg/kg), with variations in left ventricular pressure recorded throughout...

Minocycline, a glial suppressor, prevents behavioural hypersensitivities in animal models of peripheral nerve injury. However clinical trials of minocycline in human studies have produced mixed results. This study addressed two questions: can repeated injections of hypertonic saline (HS) in humans induce persistent hypersensitivity? Can pre-treatment with minocycline, a tetracycline antibiotic with microglial inhibitory effects, prevent the onset of hypersensitivity? Twenty seven healthy participants took part in this double-blind, placebo-controlled study, consisting of six test sessions across 2 weeks...

Reduction of salivary nitrate to nitrite by oral microbes expressing nitrate-reductase has emerged as a crucial pathway in systemic NO homeostasis in humans and other mammals. Selective depletion of oral microbes prevents dietary nitrate-dependent lowering of blood pressure, inhibition of platelet aggregation and ischemic injury. To date, most studies interrogate enterosalivary nitrate reduction by following changes in saliva or plasma nitrite and NO-signaling (functional) end points. Little is known about whether, and if so how, nitrate-reductase enzymatic activity per se (i...

Katherine Freundlich
Pressure injuries are a challenging problem in the care of medically complex children. Available evidence is limited, and there are theoretical reasons to use caution before extrapolating adult data, including key differences in body composition, common locations of pressure injury, and association with medical devices. The focus of this article will be to review the definition of a pressure injury and what is known about pathophysiology, prevention, recognition, staging, and treatment of pressure injuries in children with medical complexity...

Salt-sensitive hypertension (SSHT) leads to kidney interstitial fibrosis. However, the potential mechanisms leading to renal fibrosis have not been well investigated. In present study, Dahl salt-sensitive (DS) rats were divided into three groups: normal salt diet (DSN), high salt diet (DSH) and high salt diet treated with hydrochlorothiazide (HCTZ) (DSH + HCTZ). A significant increase in systolic blood pressure (SBP) was observed 3 weeks after initiating the high salt diet, and marked histological alterations were observed in DSH rats...

PURPOSE OF REVIEW: Syncope is a prevalent syndrome with diverse causes, which have in common a sudden transient failure of the autonomic nervous system to maintain blood pressure against the force of gravity at a level sufficient for cerebral perfusion. Neurally mediated syncope is an episodic phenomenon in which autonomic nervous system function is normal the rest of the time. Although relatively benign, syncope increases the risk for injury from falling and can substantially impair patients' quality of life...

We substantiated the role of peroxisome proliferator-activated receptor-γ (PPAR-γ) activation in the protective effect of apigenin against the myocardial infarction (MI) in diabetic rats. Diabetes was induced by intraperitoneal administration of a single dose of streptozotocin (55 mg/kg). The study groups included diabetic rats receiving vehicle, apigenin (75 mg/kg/day, orally), GW9662 (1 mg/kg/day, intraperitoneally), and a combination of apigenin and GW9662 for 14 days. The MI was induced in all the study groups except the diabetic control group by subcutaneous injection of 100 mg/kg/day of isoproterenol on the two terminal days...

Obesity and related disorders have increased concurrently with an increased consumption of saturated fatty acids. We examined whether post-weaning high fat (HF) diet would exacerbate offspring vulnerability to maternal HF-induced programmed hypertension and kidney disease sex-specifically, with a focus on the kidney. Next, we aimed to elucidate the gene-diet interactions that contribute to maternal HF-induced renal programming using the next generation RNA sequencing (NGS) technology. Female Sprague-Dawley rats received either a normal diet (ND) or HF diet (D12331, Research Diets) for five weeks before the delivery...
