Excessive production of pro-inflammatory cytokines such as interleukin-1β (IL-1β) plays a key role in the pathophysiological development of osteoarthritis (OA). Orexin A is an important peptide of hypothalamic origin, which has displayed its multiple biological functions in several chronic diseases via activation of its specific G-protein coupled receptors, orexin-1 receptor (OX1R) and orexin-2 receptor (OX2R). In this study, we aimed to characterize the protective effects of orexin A against IL-1β-induced degradation of articular cartilage matrixes in human chondrocytes...

OBJECTIVE: African American (AA) people with systemic lupus erythematosus (SLE) are at high morbidity and mortality risk, and they often require multiple medications. Low medication adherence is a highly prevalent, multidimensional problem associated with poor outcomes in people with SLE. Depression, a predictor of low adherence in people with chronic conditions, has been described in over 35% of AAs with SLE. We hypothesized that depressive symptoms would be increasingly associated with low adherence in this population...

We examined the differential impact of exposure to smoking-related graphic health warnings (GHWs) on risk perceptions and intentions to quit among different audience segments characterized by gender, race/ethnic group, and presence of chronic disease condition. Specifically, we sought to test whether GHWs that portray specific groups (in terms of gender, race, and chronic disease conditions) are associated with differences in risk perception and intention to quit among smokers who match the portrayed group...

Systemic Lupus Erythematosus (SLE or lupus) (OMIM: 152700) is a chronic autoimmune disease with debilitating inflammation that affects multiple organ systems. The STAT1-STAT4 locus is one of the first and most highly-replicated genetic loci associated with lupus risk. We performed a fine-mapping study to identify plausible causal variants within the STAT1-STAT4 locus associated with increased lupus disease risk. Using complementary frequentist and Bayesian approaches in trans-ancestral Discovery and Replication cohorts, we found one variant whose association with lupus risk is supported across ancestries in both the Discovery and Replication cohorts: rs11889341...

Cerebral tuberculosis TB (tuberculomas) without meningitis is an uncommon disease with a high morbidity and mortality. We report on a case that illustrates the complexity of this clinical presentation. An 11 month old, previously healthy male infant was brought to the clinic due to fever present during the last 1.5 months, associated with loss of neurodevelopmental goals and signs of endocranial hypertension. CT scan of the skull revealed dilatation of the ventricular system with transependimary edema; MRI showed multiple intra- and extra-axial micronodular images and hydrocephalus...

A number of bacteria provoking zoonotic diseases present intracellular survival and a host cell tropism limited to the monocyte/macrophage lineage. Thus, infection is rendered difficult to eradicate, causing chronic inflammatory reactions to the host and widespread prevalence. Although self-inactivating lentiviral vectors have been successfully tested in the clinic against virally-induced human infectious diseases, little is known about the transduction susceptibility of ruminant animal phagocytes that play a critical role in the outbreak of zoonotic diseases such as brucellosis...

Inflammatory bowel diseases (IBD) are chronic inflammatory conditions of the gastrointestinal tract encompassing two main clinical entities: Crohn's disease (CD) and ulcerative colitis (UC). These disorders are characterized by various grades of tissue damage and development of local complications and extra-intestinal manifestations. The cause of IBD remains unknown but accumulating evidence indicates that both CD and UC arise in genetically-predisposed individuals as a result of the action of multiple environmental factors, which ultimately trigger excessive and poorly-controlled immune response against antigens of the luminal flora...

The aim of this study was to design a system to diagnose chronic stress, based on blunted reactivity of the autonomic nervous system (ANS) to cognitive load (CL). The system concurrently measures CL-induced variations in pupil diameter (PD), heart rate (HR), pulse wave amplitude (PWA), galvanic skin response (GSR), and breathing rate (BR). Measurements were recorded from 58 volunteers whose stress level was identified using the State-Trait Anxiety Inventory. Number-multiplication questions were used as CLs...

Coronary artery disease (CAD) is considered as a chronic inflammatory disease initiated from early childhood. Nuclear factor κB (NF κB) and κB1A (NF κB1A) are the key regulators of inflammatory responses. The NFKB1 -94ATTG ins/del and NFKB1A -826C/T polymorphisms may contribute to the development of CAD. The aim of the present study was to investigate the association of these polymorphisms with the risk of CAD. The study population included 120 patients with angiographically confirmed CAD and 100 matched controls...

Current medicine and medical science puts great effort into elucidating the basis of chronicity and finding appropriate treatments for inflammatory diseases; however, the mechanisms driving aberrant immune responses are mostly unknown and deserve further study. Of particular interest is the identification of checkpoints that regulate the function and differentiation of pro-inflammatory cells during pathogenesis, along with means of their modulation for therapeutic purposes. Natural killer group 2, member D (NKG2D) is a potent activator of the immune system, known as a sensor for "induced-self" ligands, i...

Protein energy wasting (PEW) is a condition commonly occurring among patients with ESRD on hemodialysis. PEW is characterized by depletion of protein and energy stores and is caused by multiple factors related to chronic kidney disease, acute and chronic comorbidities and by renal replacement therapy itself. Anorexia is central in the pathogenesis of PEW; it is frequently observed in these patients whose protein and energy intakes are typically lower than guidelines recommendations. If untreated, PEW invariably leads to major complications, and may activate a vicious circle with further worsening of nutritional status...

Hypertension affects nearly one third of the adult US population and is a significant risk factor for chronic kidney disease (CKD). An expanding body of recent studies indicates that gut microbiome has crucial roles in regulating physiological processes through, among other mechanisms, one mode of short chain fatty acids (SCFA) and their target receptors. In addition, these SCFA receptors are potential targets of regulation by host miRNAs, however, the mechanisms through which this occurs is not clearly defined...

BACKGROUND: Frailty is associated with older age and multimorbidity (two or more long-term conditions); however, little is known about its prevalence or effects on mortality in younger populations. This paper aims to examine the association between frailty, multimorbidity, specific long-term conditions, and mortality in a middle-aged and older aged population. METHODS: Data were sourced from the UK Biobank. Frailty phenotype was based on five criteria (weight loss, exhaustion, grip strength, low physical activity, slow walking pace)...

INTRODUCTION: Acute kidney injury (AKI) is a common and serious complication after hip fracture surgery in older adults. Hypoalbuminemia is a known independent risk factor for AKI. However, few studies have investigated the relationship between early postoperative hypoalbuminemia and AKI after hip fracture surgery. Therefore, we sought to determine the incidence of and risk factors for AKI and the effects of early postoperative hypoalbuminemia on AKI incidence after surgery for hip fractures, especially intertrochanteric fractures of the proximal femur...

Ismail Sebina, Ashraful Haque
Type I interferons are a family of cytokines with a wide range of biological activities including anti-viral and immune-regulatory functions. Here, we focus on the protozoan parasitic disease, malaria, and examine the effects of type I IFN-signalling during Plasmodium infection of humans and experimental mice. Since the 1960's, there have been many studies in this area, but a simple explanation for the role of type I IFN has not emerged. Although epidemiological data are consistent with roles for type I IFN in influencing malaria disease severity, functional proof of this remains sparse in humans...

Tremendous progress in treatment and outcomes has been achieved across the whole range of haematological malignancies in the past two decades. Although cure rates for aggressive malignancies have increased, nowhere has progress been more impactful than in the management of typically incurable forms of haematological cancer. Population-based data have shown that 5-year survival for patients with chronic myelogenous and chronic lymphocytic leukaemia, indolent B-cell lymphomas, and multiple myeloma has improved markedly...

BACKGROUND: Antimicrobial treatment for acute exacerbations of chronic obstructive pulmonary disease (AECOPD) remains controversial. In some cases AECOPD are caused by microorganisms that are resistant to treatments recommended by guidelines. Our aims were: 1) identify the risk factors associated with infection by microorganisms resistant to conventional treatment (MRCT), 2) Compare the clinical characteristics and outcomes of patients with AECOPD resulting from MRCT against those with AECOPD from other causes...
