BACKGROUND/AIMS: It has become clear that metformin exerts pleiotropic actions beyond its glucose-lowering agent effect. In this review, we summarise the state of the art concerning the potential renoprotective effects of metformin in vitro, animal models and clinical nephrology. METHODS: A literature search was performed in PUBMED, ScienceDirect, between January 1957 and March 2017 using the following keywords: "metformin," "nephroprotection," "renoprotection," "survival," "renal failure," "chronic kidney diseases," "fibrosis," "polycystic kidney disease" and "microalbuminuria...

RATIONALE: The neuromuscular blocking agent cisatracurium may improve mortality for patients with moderate-severe ARDS. Other neuromuscular blocking agents, such as vecuronium, are commonly used and have different mechanisms of action, side effects, cost, and availability in the setting of drug shortages. OBJECTIVE: To determine whether cisatracurium is associated with improved outcomes when compared vecuronium in patients at risk for and with ARDS. METHODS: Using a nationally representative database, patients admitted to the intensive care unit (ICU) with a diagnosis of ARDS or an ARDS risk factor, received mechanical ventilation, and were treated with a continuous infusion of neuromuscular blocking agent for at least two days within two days of hospital admission were included...

Osteoarthritis is highly prevalent, disabling and costly to the person and the community. The burden of this chronic condition is predicted to increase dramatically over the coming decades. Healthcare spending on osteoarthritis is unsustainable and action is needed to improve care delivery. At present, there is an over-emphasis on surgical and pharmacological interventions, despite evidence supporting conservative treatments such as exercise, weight loss and education. While clinical guidelines provide recommendations regarding best practice (ie, what to do), they fail to address how to operationalise these recommendations into clinical practice...

Repetitive nerve stimulation (RNS) is a valuable diagnostic method for myasthenia gravis (MG). However, its association with clinical severity was scarcely studied. We reviewed medical records and retrospectively enrolled 121 generalized MG patients. Sensitivity of different muscles to RNS and clinical scoring systems was evaluated. RNS testing revealed facial muscles have the highest positive rate, followed by proximal muscles and distal muscles, with the palpebral portion of the orbicularis oculi muscle most sensitive...

Virtual reality is nowadays used to facilitate motor recovery in stroke patients. Most virtual reality studies have involved chronic stroke patients; however, brain plasticity remains good in acute and subacute patients. Most virtual reality systems are only applicable to the proximal upper limbs (arms) because of the limitations of their capture systems. Nevertheless, the functional recovery of an affected hand is most difficult in the case of hemiparesis rehabilitation after a stroke. The recently developed Leap Motion controller can track the fine movements of both hands and fingers...

Perceived injustice is a belief that one has been treated unfairly, disrespectfully, and is suffering unnecessarily as a result of another person's actions. Perceived injustice predicts chronic disability after musculoskeletal injury, but to our knowledge, has not been empirically studied in people with mild traumatic brain injuries (MTBIs). We examined perceived injustice and its correlates in patients who were slow to recover from MTBI. Patients (N=102) were recruited from four concussion clinics. The sample was on average 41...

We analyzed China's current use of and microbial resistance to antibiotics, and possible means of reducing antimicrobial resistance. Interventions like executive orders within clinical settings and educational approach with vertical approaches rather than an integrated strategy to curb the use of antimicrobials remain limited. An underlying problem is the system of incentives that has resulted in the intensification of inappropriate use by health professionals and patients. There is an urgent need to explore the relationship between financial and non-financial incentives for providers and patients, to eliminate inappropriate incentives...

Anabasum is a synthetic analogue of Δ8 - tetrahydrocannabinol (THC)-11-oic acid that in pre-clinical models of experimental inflammation exerts potent anti-inflammatory actions with minimal CNS cannabimimetic activity. Here we used a novel model of acute inflammation driven by i.d. UV-killed E. coli in healthy humans and found that Anabasum (5mg) exerted a potent anti-inflammatory effect equivalent to that of prednisolone in terms of inhibiting neutrophil infiltration, the hallmark of acute inflammation. These effects arose from the inhibition of the neutrophil chemoattractant LTB4 , while the inhibition of anti-phagocytic prostanoids (PGE2 , TxB2 and PGF2 α) resulted in enhanced clearance of inflammatory stimulus from the injected site...

BACKGROUND: Muscle soreness typically occurs after intense exercise, unaccustomed exercise or actions that involve eccentric contractions where the muscle lengthens while under tension. It peaks between 24 and 72 hours after the initial bout of exercise. Many people take antioxidant supplements or antioxidant-enriched foods before and after exercise in the belief that these will prevent or reduce muscle soreness after exercise. OBJECTIVES: To assess the effects (benefits and harms) of antioxidant supplements and antioxidant-enriched foods for preventing and reducing the severity and duration of delayed onset muscle soreness following exercise...

Anaphylaxis is defined as a severe life-threatening generalized or systemic hypersensitivity reaction characterized by rapidly developing airway and/or circulation problems. It presents with very different combinations of symptoms and apparently mild signs and can progress to fatal anaphylactic shock unpredictably. The difficulty in recognizing anaphylaxis is due, in part, to the variability of diagnostic criteria, which in turn leads to a delay in administration of appropriate treatment, thus increasing the risk of death...

Atsushi Shioi, Yuji Ikari
Plaque calcification develops by the inflammation-dependent mechanisms involved in progression and regression of atherosclerosis. Macrophages can undergo two distinct polarization states, that is, pro-inflammatory M1 phenotype in progression and anti-inflammatory M2 phenotype in regression. In plaque progression, predominant M1 macrophages promote the initial calcium deposition within the necrotic core of the lesions, called as microcalcification, through not only vesicle-mediated mineralization as the result of apoptosis of macrophages and vascular smooth muscle cells (VSMCs), but also VSMC differentiation into early phase osteoblasts...

While progesterone receptor (PR)-targeted therapies are modestly active in patients with uterine cancer, their underlying molecular mechanisms are not well understood. The clinical use of such therapies is limited because of the lack of biomarkers that predict response to PR-agonists (progestins) or PR-antagonists (onapristone). Thus, understanding the underlying molecular mechanisms of action will provide an advance in developing novel combination therapies for cancer patients. Nuclear translocation of PR has been reported to be ligand-dependent or -independent...

Activation of tropomyosin receptor kinase (TRK) family tyrosine kinases by chromosomal rearrangement has been shown to drive a wide range of solid tumors and hematologic malignancies. TRK fusions are actionable targets as evidenced by recent clinical trial results in solid tumors. Entrectinib (RXDX-101) is an investigational, orally available, CNS-active, highly potent and selective kinase inhibitor against TRKA/B/C, ROS1 and ALK kinase activities. Here, we demonstrate that TRK kinase inhibition by entrectinib selectively targets preclinical models of TRK fusion-driven hematologic malignancies...

Non-classical Ferroportin Disease is a form of hereditary hemochromatosis caused by mutations in the iron transporter ferroportin (Fpn), resulting in parenchymal iron overload. Fpn is regulated by the hormone hepcidin, which induces Fpn endocytosis and cellular iron retention. We characterized 11 clinically-relevant and 5 nonclinical Fpn mutations using stably transfected, inducible, isogenic cell lines. All clinical mutants were functionally resistant to hepcidin as a consequence of either impaired hepcidin binding or impaired hepcidin-dependent ubiquitination despite intact hepcidin binding...

BACKGROUND: The pharmaceutical agent pentosan polysulfate (PPS) is known to induce proliferation and chondrogenesis of mesenchymal progenitor cells (MPCs) in vitro and in vivo. However, the mechanism(s) of action of PPS in mediating these effects remains unresolved. In the present report we address this issue by investigating the binding and uptake of PPS by MPCs and monitoring gene expression and proteoglycan biosynthesis before and after the cells had been exposed to limited concentrations of PPS and then re-established in culture in the absence of the drug (MPC priming)...

However, significant shortcomings have been detected in its diagnosis and clinical management, as well as in patient outcomes. We developed the INDI collaborative care model to improve the management of depression in primary care. This intervention has been favorably evaluated in terms of clinical efficacy and cost-effectiveness in a clinical trial. Our aim is to bring this intervention from the scientific context into clinical practice...

AIM: In this study, we tested the hypothesis that lipid peroxide-derived dicarboxylic acids, by virtue of their ability bind to calcium, might be involved in atherosclerotic calcification. We determined the ability of azelaic acid (AzA) to promote calcification in human aortic smooth muscle cells (HASMC), identified AzA in human calcified atherosclerotic lesions, and compared its levels with control and non-calcified atherosclerotic lesions. RESULTS: HASMCs efficiently converted 9-oxononanoic acid (ONA), a lipid peroxide derived monocarboxylic aldehyde, to AzA...

Androgens are responsible for the development and maintenance of male sex characteristics. Dysfunctions in androgen action due to mutations in the androgen receptor gene (AR) can lead to androgen insensitivity syndrome (AIS) that can be classified as mild (MAIS), partial (PAIS), or complete (CAIS). We have analyzed functional effects of p.Ser760Thr, p.Leu831Phe, p.Ile899Phe, p.Leu769Val, and p.Pro905Arg mutations and the combination p.Gln799Glu + p.Cys807Phe that were identified in patients with PAIS or CAIS...
