In December 2011, a major revision of GOLD 2011 guidelines was published based on the evidence-based medicine. The goal of GOLD 2011 is to determine the severity of the disease, its impact on the patient's health, and the risk of future events; all of which eventually guide therapy. A combined COPD assessment according to GOLD 2011 considers the patient's level of symptoms, spirometry abnormalities, risk of exacerbation, and the presence of comorbidities. GOLD 2011 stratifies patients into four basic groups labeled A, B, C, and D...

Overdiagnosis and disease are related concepts. Widened conceptions of disease increase overdiagnosis and vice versa. This is partly because there is a close and complex relationship between disease and overdiagnosis. In order to address the problems with overdiagnosis, we may benefit from a closer understanding this relationship. Accordingly, the objective of this article is to elucidate the relationship between disease and overdiagnosis. To do so, the article starts with scrutinizing how overdiagnosis can explain the expansion of the concept of disease...

REVIEW
Paula Pierozan, Regina Pessoa-Pureur
Cytoskeletal proteins are increasingly recognized as having important roles as a target of the action of different neurotoxins. In the last years, several works of our group have shown that quinolinic acid (QUIN) was able to disrupt the homeostasis of the cytoskeleton of neural cells and this was associated with cell dysfunction and neurodegeneration. QUIN is an excitotoxic metabolite of tryptophan metabolism and its accumulation is associated with several neurodegenerative diseases. In the present review, we provide a comprehensive view of the actions of QUIN upstream of glutamate receptors, eliciting kinase/phosphatase signaling cascades that disrupt the homeostasis of the phosphorylation system associated with intermediate filament proteins of astrocytes and neurons...

Fatigue is a common complaint in patients with Parkinson's disease (PD). However, the neural bases of fatigue in PD remain uncertain. In this cross-sectional study, our aim was to study the change of the local brain function in PD patients with fatigue. Among 49 patients with PD, 17 of them had fatigue and the remaining 32 patients without fatigue, and 25 age- and gender-matched healthy controls were enrolled. All subjects were evaluated with Fatigue Severity Scale (FSS) and had a resting-state functional magnetic resonance imaging (rs-fMRI) scan...

Hepatitis E is the most common cause of hepatitis worldwide. While originally considered a disease of developing countries, it is increasingly recognised in developed countries, probably related to contaminated pork meat, and where infection is often asymptomatic. However, several non-liver manifestations have become apparent, the most important of which are neurological, including Guillain-Barré syndrome (acute inflammatory demyelinating polyradiculoneuropathy (AIDP)), neuralgic amyotrophy and meningoencephalitis...

OBJECTIVE: Magnitude and independent drivers of the risk of acute arterial events in IBD are still unclear. We addressed this question in patients with IBD compared with the general population at a nationwide level. DESIGN: Using the French National Hospital Discharge Database from 2008 to 2013, all patients aged 15 years or older and diagnosed with IBD were identified and followed up until 31 December 2013. The rates of incident acute arterial events were calculated and the impact of time with active disease (period around hospitalisation for IBD flare or IBD-related surgery) on the risk was assessed by Cox regression adjusted for traditional cardiovascular risk factors...

OBJECTIVE: Spinal cord tanycytic ependymomas (TEs) are rarely reported because of extremely low incidence. Understanding of this disease is therefore poor. The aim of this study was to analyze the incidence and clinical, radiological, pathological, and prognostic features of spinal cord TEs. METHODS: Approximately 4,000 spinal cord tumors were surgically resected in Beijing Tiantan Hospital between April 2009 and May 2016. We identified all cases of pathologically proved TEs among these patients...

BACKGROUND: Subintimal angioplasty is an alternative approach in treating critical limb ischemia with crural artery disease. However, route or location of the newly created channel is not understood. CASE PRESENTATION: A 68-year-old man was referred to our hospital with ischemic gangrene of the right big toe. We performed endovascular treatment because he was a poor candidate for bypass surgery. The posterior tibial artery was treated using subintimal angioplasty, though it resulted in early occlusion...

Napier grass Stunt Disease (NSD) is a severe disease of Napier grass (Pennisetum purpureum) in Eastern Africa, caused by the leafhopper-transmitted bacterium Candidatus Phytoplasma oryzae. The pathogen severely impairs the growth of Napier grass, the major fodder for dairy cattle in Eastern Africa. NSD is associated with biomass losses of up to 70% of infected plants. Diagnosis of NSD is done by nested PCR targeting the phytoplasma DNA, which is difficult to perform in developing countries with little infrastructure...

Alcohol-related liver disease (ALD) remains the most important cause of death due to alcohol. Infections, particularly bacterial infections, are one of the most frequent and severe complications of advanced ALD, as alcoholic cirrhosis and severe alcoholic hepatitis (sAH). The specific mechanisms responsible of this altered host defence become to be deciphered. The aim of the present work is to review the current knowledge about infectious complications in ALD and the pathophysiological mechanisms, distinguishing the role of alcohol consumption and the contribution of different forms of ALD...

BACKGROUND & AIMS: Macrophage migration inhibitory factor (MIF) is a multi-potent cytokine that contributes to the inflammatory response to injury. MIF is expressed by multiple cell types; however, the cellular source and actions of MIF in alcoholic liver disease (ALD) are not well known. Here we tested the hypothesis that non-myeloid cells, specifically hepatocytes, are an important cellular source of MIF in ALD. METHODS: MIF expression was measured in HuH7 and differentiated THP-1 cells in response to ethanol...

The intellectual disability that characterizes Down syndrome (DS) is primarily caused by prenatal changes in central nervous system growth and differentiation. However, in later life stages, the cognitive abilities of DS individuals progressively decline due to accelerated aging and the development of Alzheimer's disease (AD) neuropathology. The AD neuropathology in DS has been related to the overexpression of several genes encoded by Hsa21 including DYRK1A (dual-specificity tyrosine-(Y)-phosphorylation regulated kinase 1A), which encodes a protein kinase that performs crucial functions in the regulation of multiple signaling pathways that contribute to normal brain development and adult brain physiology...

The incidence, severity and progression of autoimmune diseases (e.g. scleroderma, multiple sclerosis, rheumatoid arthritis) and certain inflammatory diseases (e.g. asthma) are sex-biased where these pathologies dominate in women. However, other immune disorders such as sepsis, post-surgery infections and gout display higher incidence and severity in men. The molecular and cellular basis underlying this sex dimorphism remains incompletely elucidated but may provide important insights for sex-specific pharmacotherapy...

Oxidation-associated malondialdehyde (MDA) modification of proteins can generate immunogenic neo-epitopes that are recognized by autoantibodies. In health, IgM antibodies to MDA-adducts are part of the natural antibody pool, while elevated levels of IgG anti-MDA antibodies are associated with inflammatory and autoimmune conditions. Yet, in human autoimmune disease IgG anti-MDA responses have not been well characterized and their potential contribution to disease pathogenesis is not known. Here, we investigate MDA-modifications and anti-MDA-modified protein autoreactivity in rheumatoid arthritis (RA)...

Targeting plasma IgE by therapeutic mABs like Omalizumab (Xolair®) is current clinical practice for severe allergic conditions or other IgE related diseases like chronic urticaria. As an alternative to soluble IgE targeting, IgE supply can be lowered by targeting the Extracellular Membrane Proximal Domain (EMPD) of the IgE B cell receptor (BCR) present on IgE switched B cells. This ultimately leads to apoptosis of these cells upon IgE BCR crosslinking. Since tools to selectively assess the efficacy of IgE BCR crosslinking by IgE targeting antibodies are limited, a readily quantifiable cell model was developed that allows to specifically address IgE BCR crosslinking activity in vitro...
