Periodontitis is a chronic oral inflammatory disease produced by bacteria. Gingival retraction and bone and connective tissues resorption are the hallmarks of this disease. Chronic periodontitis may contribute to the risk of onset or progression of neuroinflammatory pathological conditions, such as Alzheimer's disease. The main goal of the present study was to investigate if the role of epigenetic modulations is involved in periodontitis using human periodontal ligament stem cells (hPDLSCs) as an in vitro model system...

Skin cells can respond to UVB-induced damage either by tolerating it, or restoring it through antioxidant activation and DNA repair mechanisms or, ultimately, undergoing programmed cell death, when damage is massive. Nutritional factors, in particular, food antioxidants, have attracted much interest because of their potential use in new preventive, protective, and therapeutic strategies for chronic degenerative diseases, including skin inflammation and cancer. Some polyphenols, present in virgin olive oil, well tolerated by organism after oral administration, show a variety of pharmacological and clinical benefits such as anti-oxidant, anti-cancer, anti-inflammatory, and neuro-protective activities...

Innate lymphoid cells (ILCs) are lymphocytes lacking antigen recognition receptors and become activated in response to cytokines and through microbe-associated molecular pattern (MAMP) receptors. ILCs are found mainly in mucosal tissues and participate in the immune response against infections and in chronic inflammatory conditions. ILCs are divided in ILC-1, ILC-2 and ILC-3, and these cells have analogue functions to those of immune adaptive response lymphocytes Th1, Th2 and Th17. ILC-1 express T-bet, produce IFNγ, protect against infections with intracellular microorganisms and are related to inflammatory bowel disease immunopathology...

Chronic obstructive pulmonary disease (COPD) is a common, preventable and treatable condition that has a complex pathophysiology and an even more complex immunopathological process. The purpose of this review was to analyze COPD immunopathological aspects, which was addressed by undertaking a literature search for the most relevant documents indexed in the PubMed database over the last 10 years. Different conclusions could be drawn: in COPD immunopathology there are immune and non-immune inflammatory changes with oxidative stress imbalance, there are alterations in the protease/anti-protease ratio caused by direct and indirect genetic and epigenetic-environmental defects; COPD produces irreversible tissue damage and chronic inflammation with tissue repair alteration, which induces chronic obstruction of the airway, bronchitis and systemic damage...

OBJECTIVE: The aim of this study is to determine if the pattern of monthly medical expense can be used to identify individuals at risk of dying, thus supporting providers in proactively engaging in advanced care planning discussions. BACKGROUND: Identifying the right time to discuss end of life can be difficult. Improved predictive capacity has made it possible for nurse leaders to use large data sets to guide clinical decision making. METHODS: We examined the patterns of monthly medical expense of Medicare beneficiaries with life-limiting illness during the last 24 months of life using analysis of variance, t tests, and stepwise hierarchical linear modeling...

Stridor is a result of turbulent air-flow through the trachea from upper airway obstruction, and although in children it is often due to croup, it can also be caused by noninfectious and/or congenital conditions as well as life-threatening etiologies. The history and physical examination guide initial management, which includes reduction of airway inflammation, treatment of bacterial infection, and, less often, imaging, emergent airway stabilization, or surgical management. This issue discusses the most common as well as the life-threatening etiologies of acute and chronic stridor and its management in the emergency department...

Skin tears represent a common condition of traumatic wounds, which may be encountered in some categories of individuals at the extremes of age, such as infants and the elderly. Despite the high prevalence and cost of these lesions, there has been little investigation into the risk factors that lead to this condition. The aim of this review was to systematically evaluate the main risk factors involved in development of skin tears. We planned to include all the studies dealing with risk factors related to skin tears...

Macrophages infiltrating the allografts are heterogeneous, consisting of pro-inflammatory (M1 cells) as well as anti-inflammatory and fibrogenic phenotypes (M2 cells); they affect transplant outcomes via diverse mechanisms. Herein, we found that macrophage polarization into M1 and M2 subsets was critically dependent on TRAF6 and mTOR, respectively. In a heart transplant model we showed that macrophage-specific deletion of TRAF6 (LysM(C)(re) Traf6(fl/fl) ) or mTOR (LysM(C)(re) Mtor(fl/fl) ) did not affect acute allograft rejection...

Neuroinflammation has been reported to follow chronic ethanol intake and may perpetuate alcohol consumption. Present studies determined the effect of human mesenchymal stem cells (hMSCs), known for their anti-inflammatory action, on chronic ethanol intake and relapse-like ethanol intake in a post-deprivation condition. Rats were allowed 12-17 weeks of chronic voluntary ethanol (10% and 20% v/v) intake, after which a single dose of activated hMSCs (5 × 10(5) ) was injected into a brain lateral ventricle...

BACKGROUND: Since 2006, human papillomavirus (HPV) vaccines have been introduced in many countries worldwide. Whilst safety studies have been reassuring, focus has been on the primary target group, the young adolescent girls. However, it is also important to evaluate safety in adult women where background disease rates and safety issues could differ significantly. OBJECTIVE: We took advantage of the unique Danish and Swedish nationwide healthcare registers to conduct a cohort study comparing incidence rate ratios (RRs) of 45 preselected serious chronic diseases in quadrivalent HPV (qHPV)-vaccinated and qHPV-unvaccinated adult women 18-44 years of age...

Historically, osteoporosis has not been considered a public health priority for the Hispanic population. However, recent data indicate that Mexican Americans are at increased risk for this chronic condition. Although it is well established that there is heterogeneity in social, lifestyle, and health-related factors among Hispanic subgroups, there are currently few studies on bone health among Hispanic subgroups other than Mexican Americans. The current study aimed to determine the prevalence of osteoporosis and low bone mass (LBM) among 953 Puerto Rican adults, aged 47 to 79 yr and living on the U...

BACKGROUND: Permanent hypoparathyroidism is a serious problem and requires medications indefinitely. Parathyroid allotransplantation (PA) with short-term immunosuppression is definitive choice but long-term results are not clear. METHOD: We performed PA from two donors to two recipients. Both recipients were 39-year-old females. Donors were a 32-year-old female and a 36-year-old male, who both have chronic kidney disease. Routine tests, viral markers, and cross-matches were analyzed individually...

The term "neuroinflammation" has been widely used to describe a series of acute or chronic conditions that cause inflammation in the central nervous system (CNS). Neurological damage can be a consequence of direct local injury or, secondary, of systemic or even distant inflammatory processes. In this respect, animal models have been developed to better understand the pathophysiology and, possibly, to evaluate more effective methods of treatment for these disorders. Animal models that promote alterations in blood-brain barrier permeability-the activation of microglia or astrocytes, modifications in neuropeptide expression, oxidative stress, increased apoptosis, release of inflammatory mediators, leukocyte infiltration, and brain edema-are likely to involve neuroinflammation and therefore can serve as useful models for human inflammatory CNS injury...

Chronic muscle ischemia leads to accumulation of lactic acid and other inflammatory mediators with a subsequent drop in interstitial pH. Acid-sensing ion channels (ASICs), expressed in thin muscle afferents, sense the decrease in pH and evoke a pressor reflex known to increase mean arterial pressure. The naturally occurring endomorphins are also released by primary afferents under ischemic conditions. We examined whether high affinity mu opioid receptor (MOR) agonists, endomorphin-1 (E-1) and -2 (E-2), modulate ASIC currents and the lactic acid-mediated pressor reflex...

BACKGROUND: Chronic heart failure (HF) is a relevant and growing public health problem. Although the prognosis has recently improved, it remains a lethal disease, with a mortality that equals or exceeds that of many malignancies. Furthermore, chronic HF is costly, representing a large and growing drain on healthcare resources. METHODS: This narrative review is based on the material searched for and obtained via PubMed up to May 2017. The search terms we used were: "heart failure, echocardiography, natriuretic peptides" in combination with "treatment, biomarkers, guidelines"...

Based on results of the 2012 Canadian Community Health Survey-Mental Health, 1.2% of Canadians aged 15 to 64 (an estimated 282,000) experienced mental and substance use disorders concurrently in the previous year (at least one mood/anxiety disorder and one substance use disorder). Demographic, socioeconomic, health status and service use characteristics of the concurrent disorder group were compared with those of people who had only a mood/ anxiety disorder or only a substance use disorder. Those with concurrent disorders had consistently poorer psychological health and higher use of health services and were more likely to report partially met/unmet needs than the substance use disorder group, even when demographic and socioeconomic factors and number of chronic health conditions were taken into account...

Acquired Cystic Kidney Disease (ACKD) is regarded as a common late condition of end stage renal damage and expresses its most important features when associated with long term hemodialysis. ACKD is also widely known as a premalignant lesion. Its occurrence in chronically rejected renal allografts is rare and its frequency and behavior in this setting are not well known. Herein we report a case of ACKD in a long standing nonfunctional allograft (215 months) which is not associated with malignancy and briefly review the related literature...
