For over 50 years patients with liver cirrhosis were considered to be at markedly increased risk of bleeding. This dogma was seemingly supported by abnormalities in standard laboratory tests (SLTs), such as the prothrombin time, that were interpreted as indicating a bleeding diathesis. However, publications from the last decade have revealed SLTs to be poor predictors of bleeding and it is now understood that stable patients with cirrhosis have a rebalanced haemostatic system and preserved thrombin generation...

This study utilized 2D-DIGE, isotope-coded protein labelling (ICPL) and biochemical assays to characterize protein alteration in Ulcerative Colitis (UC) and Crohn's Disease (CD) in human epithelial cell and mucosal biopsies in Inflammatory Bowel Disease (IBD)-affected patients. The aim of this study is to identify the key molecular signatures involved in epithelial cell structure of IBDs. In non-inflamed UC (QUC) keratins, vimentin and FAK increased, whereas vinculin and de-tyrosinated α-tubulin decreased; inflammation (IUC) exacerbated molecular changes, being COL6A1, tenascin-C and vimentin increased...

Myocardial ischemia culminates in ATP production impairment, ionic derangement and cell death. The provision of metabolic substrates during reperfusion significantly increases heart tolerance to ischemia by improving mitochondrial performance. Under normoxia, glutamate contributes to myocardial energy balance as substrate for anaplerotic reactions, and we demonstrated that the Na(+)/Ca(2+) exchanger1 (NCX1) provides functional support for both glutamate uptake and use for ATP synthesis. Here we investigated the role of NCX1 in the potential of glutamate to improve energy metabolism and survival of cardiac cells subjected to hypoxia/reoxygenation (H/R)...

BACKGROUND: Intrahepatic microvascular derangements and microcirculatory dysfunction are key in the development of liver cirrhosis and its associated complications. While much has been documented relating to cirrhosis and the dysfunction of the microcirculation in the liver parenchyma, far less is known about the state of the extrahepatic microcirculation and the role this may have in the pathogenesis of multiple organ failure in end stage liver cirrhosis. AIM: To provide an update on the role of the microcirculation in the pathophysiology of cirrhosis and its associated complications and briefly discuss some of the imaging techniques which may be used to directly investigate the microcirculation...

Cardiomyopathy is a serious complication of diabetes mellitus and occurs independently of coronary artery disease or hypertension. It manifests as systolic/diastolic dysfunction and hypertrophy of the left ventricle and can lead to heart failure. Hyperglycemia can trigger a series of maladaptive stimuli and result in cardiac hypertrophy, fibrosis and reduced performance and contractility. The pathogenesis of diabetic cardiomyopathy is a multifactorial process that includes metabolic derangements such as increased oxidative stress, and altered non-oxidative glucose pathways and lipid metabolism...

Heart Failure (HF), a common end point for many cardiovascular diseases, is a syndrome with a very poor prognosis. Although clinical trials in HF have achieved important outcomes in reducing mortality, little is known about functional mechanisms conditioning health improvement in HF patients. In parallel with clinical studies, basic science has been providing important discoveries to understand the mechanisms underlying the pathophysiology of HF, as well as to identify potential targets for the treatment of this syndrome...

BACKGROUND: The induction of CD80 on podocytes has been shown in animal models of podocyte injury and in certain cases of nephrotic syndrome. In a lipopolysaccharide (LPS)-induced mouse model of albuminuria, we have recently shown a signalling axis of LPS-myeloid cell activation-TNFα production-podocyte CD80 induction-albuminuria. Therefore, in this report, we investigated the cellular and molecular consequences of TNFα addition and CD80 expression on cultured podocytes. METHODS: A murine podocyte cell line was used for TNFα treatment and for over-expressing CD80...

Mechanical low back pain (LBP) is an injury or derangement of an anatomic structure in the low back. When evaluating patients with LBP, clinicians should maintain clinical suspicion for vertebral fracture, cancer, and cauda equina syndrome. Management includes patient education focused on exercise, massage, and behavioral approaches such as cognitive behavioral therapy. Acupuncture can be an effective alternative and specific herbal supplements may provide short-term pain relief. The prognosis for patients with mechanical LBP is good...

REVIEW
Chiara Berteotti, Alessandro Silvani
Narcolepsy is a rare disease that entails excessive daytime sleepiness, often associated with sudden episodes of muscle weakness known as cataplexy. Narcolepsy with cataplexy (NC) is due to the loss of hypothalamic neurons that release the neuropeptides orexin A and B. Orexin neuron projections prominently target brain structures involved in wake-sleep state switching and the central autonomic network. This review provides an updated summary of the links between NC and autonomic cardiovascular dysfunction from a translational perspective...

Among the many organ systems affected by harmful alcohol use, the lungs are particularly susceptible to infections and injury. The mechanisms responsible for rendering people with alcohol use disorder (AUD) vulnerable to lung damage include alterations in host defenses of the upper and lower airways, disruption of alveolar epithelial barrier integrity, and alveolar macrophage immune dysfunction. Collectively, these derangements encompass what has been termed the "alcoholic lung" phenotype. Alcohol-related reductions in antioxidant levels also may contribute to lung disease in people with underlying AUD...

Cocaine is the third most common substance of abuse after cannabis and alcohol. The use of cocaine as an illicit substance is implicated as a causative factor for multisystem derangements ranging from an acute crisis to chronic complications. Vasospasm is the proposed mechanism behind adverse events resulting from cocaine abuse, acute ischemic strokes (AIS) being one of the few. Our study looked into in-hospital outcomes owing to cocaine use in the large population based study of AIS patients. Using the national inpatient sample (NIS) database from 2014 of United States of America, we identified AIS patients with cocaine use using International Classification of Disease, Ninth Revision (ICD-9) codes...
