    Introduction Whereas the overall association between smoking and rheumatoid arthritis (RA) must be regarded as established, considerably less is known about how much smoking is needed to increase the risk of RA, that is, the effect of smoking intensity, duration and cessation. Methods The Swedish Mammography Cohort, including 34,101 women aged 54 to 89 years, was followed up from January 1, 2003 through December 31, 2010 (219 RA cases identified). Relative risks (RR) and their 95% confidence intervals (CI) were estimated as rate ratios using Cox proportional hazards model. Results There was a statistically significant association between smoking intensity (RR comparing 1 to 7 cigarettes/day vs never smoking 2.31 (95% CI: 1.59, 3.36)) as well as duration of smoking (comparing 1 to 25 years vs never smoking RR = 1.60 (95% CI: 1.07, 2.38)) and risk of RA. Compared to never smokers, the risk was still significantly elevated 15 years after smoking cessation (RR = 1.99 (95% CI: 1.23, 3.20)). However, among former smokers, the risk of RA seemed to be decreasing over time since stopping smoking: women who stopped smoking 15 years before the start of the follow-up had 30% lower risk of RA compared to those who stopped only a year before start of the follow-up (RR = 0.70 (95% CI: 0.24,2.02)). Conclusions This prospective study highlights that even light cigarette smoking is associated with increased risk of RA in women and that smoking cessation may reduce, though not remove, this risk.

    Full Text Available Psoriatic arthritis (PsA is an inflammatory arthritis associated with psoriasis. In addition to skin and joint involvement, there is increasing evidence suggesting that patients with PsA also have an increase in risk of clinical and subclinical cardiovascular diseases, mostly due to accelerating atherosclerosis. Both conventional and nonconventional cardiovascular risk factors contribute to the increased cardiovascular risk in PsA. Chronic inflammation plays a pivotal role in the pathogenesis of atherosclerosis in PsA, acting independently and/or synergistically with the conventional risk factors. In this paper, we discuss the current literature indicating that patients with PsA are at risk of cardiovascular diseases.

    Objective. To determine whether the incidence of malignancy is increased in patients with rheumatoid arthritis (RA) compared to a matched comparison cohort and to identify risk for any individual malignancy in RA. Methods. A cohort of 813 Olmsted County, Minnesota, residents who first fulfilled 1987 ACR criteria for RA in 1980–2007 was previously identified by medical record review. Medical records of 813 RA cases and a comparison cohort of age and sex matched Olmsted County residents without RA were evaluated retrospectively for cancer occurrence. Patients in both cohorts were followed until death, migration from Olmsted County, or 12/31/2014. Results. The RA and non-RA cohorts (mean age at incidence/index date: 55.9 [SD: 15.7] years; 68.4% females in both cohorts) were followed on average of 14.1 (SD: 7.7) and 14.9 (SD: 8.1) years, respectively. Prior to RA incidence/index date, 52 RA patients and 66 non-RA subjects had malignancies excluding NMSC (p = 0.21). During follow-up, significantly more malignancies occurred in patients with RA (n = 143) than in comparator subjects (n = 118; hazard ratio: 1.32; p = 0.027). Inclusion of NMSC obviated this difference. Conclusion. After excluding NMSC, there was a small to moderately increased risk of malignancies in patients with RA. Cancer surveillance is imperative in all patients with RA.

  12. Fetal Risks, Relative Risks, and Relatives' Risks.

    2016-01-01

    Several factors related to fetal risk render it more or less acceptable in justifying constraints on the behavior of pregnant women. Risk is an unavoidable part of pregnancy and childbirth, one that women must balance against other vital personal and family interests. Two particular issues relate to the fairness of claims that pregnant women are never entitled to put their fetuses at risk: relative risks and relatives' risks. The former have been used-often spuriously-to advance arguments against activities, such as home birth, that may incur risk; the latter implicate the nature of relationships in determining the acceptability of coercing or precluding activities. Motivated reasoning by clinicians and judges leads to inaccurate risk assessments, and judgments based on false claims to objectivity. Such judgments undermine the moral and legal standing of pregnant women and do not advance the interests of fetuses, pregnant women, families, or states. PMID:26832079

    Introduction Juvenile idiopathic arthritis (JIA) is an umbrella term for all chronic childhood arthropathies and can be divided into seven subtypes. It includes the enthesitis related arthritis (ERA) subtype which displays symptoms similar to ankylosing spondylitis (AS) and juvenile-onset psoriatic arthritis which has similarities to psoriatic arthritis (PsA) and psoriasis (Ps). We, therefore, hypothesized that two well-established susceptibility loci for AS and Ps, ERAP1 and IL23R, could als...

    Since cardiovascular disease (CVD) is the most common cause of mortality in patients with rheumatoid arthritis (RA), we aimed to determine factors associated with such a complication in a large series of Colombian patients. This was a cross-sectional analytical study in which 800 consecutive Colombian patients with RA were assessed for variables associated with CVD. Furthermore, a systematic literature review was performed to address the state of the art about non-traditional risk factors for CVD in RA. The preferred reporting items for systematic reviews and meta-analyses guidelines were followed in data extraction, analysis, and reporting of articles selected. Hypercholesterolemia, type 2 diabetes mellitus, abnormal body mass index, abdominal obesity, and current smoking were all traditional risk factors significantly associated with CVD in Colombians. As non-traditional risk factors, familial autoimmunity, more than 10 years of duration of the disease, patients working on household duties, use of systemic steroids, and low education level were associated with CVD in the studied population. Out of a total of 9,812 articles identified in PubMed and Scopus databases, 140 fulfilled the eligibility criteria and were included. Through this systematic review, several factors and outcomes related to CVD were confirmed and identified. These were categorized into genetics, RA-related, and others. Traditional risk factors do not completely explain the high rates of CVD in patients with RA; thus, novel risk factors related to autoimmunity are now recognized predicting the presence of CVD as strong as traditional risk factors. Our results may assist health professionals and policymakers in making decisions about CVD in patients with RA. PMID:23584985

    Two patients with rheumatoid arthritis developed pancytopenia during treatment with azathioprine 100 mg daily. In one patient this side effect occurred after three weeks, in the other after eight weeks of treatment. Rapid fall of platelets in one patient necessitated platelet transfusion. In the other patient additional treatment with allopurinol was probably responsible for the toxic effect. Haematological side effects of azathioprine are discussed.

    Full Text Available Introduction: Some of the studies have shown that RA (Rheumatoid Arthritis may cause hearing disorders. These disorders can result in problems later in life, so survey of correlation between rheumatoid arthritis and hearing disorders is important . Methods: This was a case-control study which has done from December 2004 to August 2006 at Shaheed Sadoughi hospital in Yazd. In this study, 50 Rheumatoid arthritis patients as case group (100 ears with 50 persons as control group who were of the same age, sex and job (100 ears were compared. Results: Patients were 21-67 years old and the mean age was 47.58 years(It was the same as the control group.From 50 cases (controls 42 were women and 8 were men . Audiometric tests in different frequencies showed that hearing loss in high frequencies, especially in 8000 Hz was significantly different in the two groups. Also, acoustic reflex was absent in case group and this too was significantly different.The evaluation of sensory neural hearing loss showed that this hearing loss was sensory, not neural . Conclusion: In Rheumatoid arthritis, middle and inner ear disorders have been shown. But some patients aren't aware of their hearing loss and they have no clinical complains, so frequent evaluation of audiometric tests is recommended. Hearing disorders can be controlled by therapeutic and rehabilitation procedures in these patients.

    The purpose of this investigation was to assess the clinical characteristics, therapeutic aspects, and outcome of arthritis related to invasive meningococcal disease (IMD). All episodes of bacterial meningitis and IMD are recorded systematically. We selected all episodes of IMD, with or without meningitis, that presented arthritis. From 1977 to 2010, 522 episodes of IMD were treated. Thirty-nine of these (7.5 %, 26 women, mean age 33 years) presented arthritis. Of these 39, 37 (95 %) presented skin lesions and 31 (79 %) had meningitis. Twenty (51 %) had positive blood cultures and six (15 %) had shock. No differences were found in skin lesions, shock, or bacteremia compared to cases without arthritis. In contrast to other septic forms, arthritis related to IMD was cured with short antibiotic therapy and without surgical drainage. There was no mortality. All patients recovered and none presented joint sequelae; however, 13 adult patients (33 %) required long-term treatment with steroids due to persistent symptoms. Arthritis related to IMD most frequently affects the knees and ankles, and may be a cause of fever relapse. Short antibiotic therapy is enough in all cases and surgical drainage is not needed. In some adult patients, especially those over 50 years of age, evolution is torpid and steroid therapy may be required in order to achieve recovery. PMID:22476361

    Full Text Available Introduction In the last three decades numerous epidemiologic studies have shown the correlation between risk factors and cardiovascular diseases. Clinical research has proven that rheumatoid arthritis patients (RA have higher prevalence of classical risk factors in relation to general population, and over the last few years there has been an emphasis on some new risk factors which can contribute to cardiovascular diseases (CVD. Material and methods This study examined risk factor values for CVD in 88 patients with RA treated at Rheumatology Department, Clinical Hospital Center, Zemun. All patients have been thoroughly examined (clinical findings, laboratory and echocardiographic examination. Apart from classical factors, 'new' risk factors have been examined in all patients: C-reactive proteine (CRP, high-sensitive C-reactive proteine (hs-CRP and homocystein. Results It has been determined that RA patients have more frequent higher new risk factors in comparison to classical ones. 84.1% of patients had higher CRP values, 97.1% had hsCRP and 39.5% had homocystein. The mean CRP values, especially hsCRP have been higher in patients with positive rheumatoid factor finding. Discussion Rheumatoid arthritis patients may have worse 'background atherosclerosis' than even subjects matched for classical cardiovascular risk factors. Continuous exposure to high grade systemic inflammation may be linked to accelerated atherosclerosis. Conclusions Timely identification of patients with risk factors, particularly with new risk factors, enables adequate approach in prevention of and treatment for CVD in rheumatoid arthritis patients.

    An epidemiological survey, accompanied by a serological analysis,was conducted on samples taken from Lebanese goat herds in order to determine the prevalence of infection with the caprine arthritis encephalitis virus (CAEV) in Lebanon. The results of the survey provided information on various livestock production, animal health and herd management factors. Serum samplesfrom 952 goats, including the local breeds (Baladi and Damascene) and imported breeds (Alpine and Saneen), were taken from 60 farms distributed throughout Lebanon and tested for the presence of anti-CAEV antibodies. The data obtained were analysed using a statistical model to assess CAEV infection risk factors in Lebanon. In total, 125 samples proved to be positive, representing a prevalence in selected individuals of 13.1% and in selected herds of 51.7%. The Bekaa region had the highest number of herds with seropositive goats (90% of herds); the level was lower in Mount Lebanon, the North and the South (54%, 34% and 33%, respectively). The prevalence in relation to the livestock production system was 70% in herds in intensive systems, 54% in semi-intensive systems and 45% in extensive systems. The indigenous breeds were more resistant and tolerant of CAEV than the imported breeds. This study confirms the presence of CAEV in Lebanese goat herds and identifies the different livestock production practices likely to favour the rapid spread of the virus. PMID:27044161

    Full Text Available The objective was to evaluate the frequency of cardiovascular risk factors and hypertension in patients with rheumatoid arthritis depending on body weight. The study involved 100 patients with rheumatoid arthritis and stably selected therapy for more than 6 months at the age from 45 to 65 years (mean age 53,19 ± 5,40 years. Traditional cardiovascular risk was assessed, taking into account risk factors by SCORE scale and amended for patients with RA. The levels of total cholesterol, triglycerides, C-reactive protein, serum creatinine, body mass index, body area index were determined. Arterial hypertension was diagnosed in 41 (41% patients with rheuma¬toid arthritis and was associated with traditional risk factors (age, obesity, rheumatoid factor, hyperuricemia and the duration of glucocorticoid therapy. Obesity and excess body mass occurred in the majority of patients with rheumatoid arthritis, herewith the highest level of inflammation indicators and risk of cardiovascular events was in overweight patients. Obesity was associated with duration of rheumatoid arthritis, the activity of the inflammatory process, the duration of glucocorticoids taking. It is found that the traditional SCORE scale does not fully reflect the risk of cardiovascular events in rheumatoid arthritis. Identification of hypertension and obesity increases the information content of the risk assessment of cardiovascular events in rheumatoid arthritis.

    Hansen, Frank

    We consider the risk premium demanded by a decision maker with wealth x in order to be indifferent between obtaining a new level of wealth y1 with certainty, or to participate in a lottery which either results in unchanged present wealth or a level of wealth y2 > y1. We define the relative risk...... premium as the quotient between the risk premium and the increase in wealth y1–x which the decision maker puts on the line by choosing the lottery in place of receiving y1 with certainty. We study preferences such that the relative risk premium is a decreasing function of present wealth, and we determine....... Decreasing relative risk premium in the small implies decreasing relative risk premium in the large, and decreasing relative risk premium everywhere implies risk aversion. We finally show that preferences with decreasing relative risk premium may be equivalently expressed in terms of certain preferences on...

  14. TNF-alpha antagonism and cancer risk in rheumatoid arthritis: is continued vigilance warranted?

    Science.gov (United States)

    Park, Hyon Ju; Ranganathan, Prabha

    2012-03-01

    Rheumatoid arthritis (RA) is a chronic, systemic inflammatory arthritis that can lead to significant damage and dysfunction of involved joints. Prior to 1998, treatment options were limited to disease modifying anti-rheumatic drugs, commonly referred to as DMARDs like methotrexate, sulfasalazine, hydroxychloroquine, and gold salts. Tumor necrosis factor alpha (TNF-α) is a central cytokine that drives the inflammation in RA; hence inhibition of TNF-α offers an attractive treatment strategy in RA. The introduction of TNF-α inhibitors, a class of biologic DMARDs, has dramatically changed the treatment of RA as these are highly effective therapies. Medication-related adverse events remain a major problem in health care. This is true of the TNF-α antagonists as well, with particular concerns about increased risks of infections and malignancy. Because clinical trials performed prior to medication approval are limited by the number and clinical complexity of participants and the duration of the trials, post-marketing surveillance is critical in identifying adverse events. In order to better clarify the safety issues related to the use of TNF-α inhibitors in RA, several studies using large observational registries along with pooled meta-analyses of these studies have been published. This review will summarize the data from these recent studies on the question of malignancy risk associated with TNF-α inhibitor use in RA. It is comforting that the data from these studies do not support an increased risk of cancer, except non-melanoma skin cancer, with the use of TNF-α antagonists in adults with RA. PMID:22463799

    Full Text Available Abstract Background The aetiology of juvenile idiopathic arthritis (JIA is largely unknown. We have established a JIA biobank in Melbourne, Australia called CLARITY – ChiLdhood Arthritis Risk factor Identification sTudY, with the broad aim of identifying genomic and environmental disease risk factors. We present here study protocols, and a comparison of socio-demographic, pregnancy, birth and early life characteristics of cases and controls collected over the first 3 years of the study. Methods Cases are children aged ≤18 years with a diagnosis of JIA by 16 years. Controls are healthy children aged ≤18 years, born in the state of Victoria, undergoing a minor elective surgical procedure. Participant families provide clinical, epidemiological and environmental data via questionnaire, and a blood sample is collected. Results Clinical characteristics of cases (n = 262 are similar to those previously reported. Demographically, cases were from families of higher socio-economic status. After taking this into account, the residual pregnancy and perinatal profiles of cases were similar to control children. No case-control differences in breastfeeding commencement or duration were detected, nor was there evidence of increased case exposure to tobacco smoke in utero. At interview, cases were less likely to be exposed to active parental smoking, but disease-related changes to parent behaviour may partly underlie this. Conclusions We show that, after taking into account socio-economic status, CLARITY cases and controls are well matched on basic epidemiological characteristics. CLARITY represents a new study platform with which to generate new knowledge as to the environmental and biological risk factors for JIA.

  19. Cigarette smoking and risk of rheumatoid arthritis: a dose-response meta-analysis

    Science.gov (United States)

    2014-01-01

    Introduction Although previous studies found that cigarette smoking is associated with risk of rheumatoid arthritis (RA), the dose-response relationship remains unclear. This meta-analysis quantitatively summarizes accumulated evidence regarding the association of lifelong exposure to cigarette smoking assessed as pack-years with the risk of RA. Methods Relevant studies were identified by a search of MEDLINE and EMBASE from 1966 to October 2013, with no restrictions. Reference lists from retrieved articles were also reviewed. Studies that reported relative risks (RR) or odds ratio (OR) estimates with 95% confidence intervals (CIs) for the association between pack-years of cigarette smoking and rheumatoid arthritis were included in a dose-response random-effects meta-regression analysis. Results We included 3 prospective cohorts and 7 case-control studies in the meta-analysis. They included a total of 4,552 RA cases. There was no indication of heterogeneity (Pheterogeneity = 0.32) and publication bias did not affect the results. Compared to never smokers, the risk of developing RA increased by 26% (RR = 1.26, 95% CI 1.14 to 1.39) among those who smoked 1 to 10 pack-years and doubled among those with more than 20 pack-years (RR for 21 to 30 pack years = 1.94, 95% CI 1.65 to 2.27). The risk of RA was not increasing further for higher exposure levels (RR for >40 pack-years = 2.07, 95% CI 1.15 to 3.73). The risk of RA was statistically significantly higher among rheumatoid factor (RF)-positive RA cases (RR = 2.47, 95% CI 2.02 to 3.02) compared to RF-negative (RR = 1.58, 95% CI 1.15 to 2.18) when comparing the highest versus lowest category of pack-years for the individual studies. Conclusions Lifelong cigarette smoking was positively associated with the risk of RA even among smokers with a low lifelong exposure. The risk of RA did not further increase with an exposure higher than 20 pack-years. PMID:24594022

    The project, within which this work report was prepared, aimed to complement the Vaermeforsk publication 'Handbook of fuels' on fuel related risks and measures to reduce the risks. The fuels examined in this project where the fuels included in the first version of the handbook from 2005 plus four additional fuels that will be included in the second and next edition of the handbook. Following fuels were included: woodfuels (sawdust, wood chips, powder, briquettes), slash, recycled wood, salix, bark, hardwood, stumps, straw, reed canary grass, hemp, cereal, cereal waste, olive waste, cocoa beans, citrus waste, shea, sludge, forest industrial sludge, manure, Paper Wood Plastic, tyre, leather waste, cardboard rejects, meat and bone meal, liquid animal and vegetable wastes, tall oil pitch, peat, residues from food industry, biomal (including slaughterhouse waste) and lignin. The report includes two main chapters; a general risk chapter and a chapter of fuel specific risks. The first one deals with the general concept of risk, it highlights laws and rules relevant for risk management and it discuss general risks that are related to the different steps of fuel handling, i.e. unloading, storing, processing the fuel, transportation within the facility, combustion and handling of ashes. The information that was used to produce this chapter was gathered through a literature review, site visits, and the project group's experience from risk management. The other main chapter deals with fuel-specific risks and the measures to reduce the risks for the steps of unloading, storing, processing the fuel, internal transportation, combustion and handling of the ashes. Risks and measures were considered for all the biofuels included in the second version in the handbook of fuels. Information about the risks and risk management was gathered through interviews with people working with different kinds of fuels in electricity and heat plants in Sweden. The information from

  1. Characteristics of Rheumatoid Arthritis relative to HLA-DR in Saudi Arabia

    International Nuclear Information System (INIS)

    The objective was to determine the clinical characteristics of rheumatoid arthritis in Saudi Arabia in relation to human leukocyte antigen type. A group of 91 rheumatoid arthritis patients, 72 females and 19 males were studied for the various clinical, laboratory and radiological parameters along with human leukocyte antigen-DR phenotypes. Since human leukocyte antigen-DR10 was most commonly associated with rheumatoid arthritis in our population, we compared those patients with human leukocyte antigen-DR10 to those without. The comparison yielded differences in the presence of rheumatoid nodules, erosions, corticosteroid treatment, and joint involvement at presentation, hemoglobin levels, and white cell count. Only the last 3 parameters showed a statistical significance. Human leukocyte antigen type of Saudi patients with rheumatoid arthritis influenced the course of the disease but only to a limited extent. (author)

    Objective To examine whether polymorphisms in genes coding for drug metabolizing enzymes (DMEs) impact rheumatoid arthritis (RA) risk due to cigarette smoking in African Americans. Methods Smoking status was evaluated in African American RA cases and non-RA controls categorized as heavy (≥ 10 pack-years) vs. other. Individuals were genotyped for a homozygous deletion polymorphism in glutathione S-transferase Mu-1 (GSTM1-null) in addition to tagging single nucleotide polymorphisms (SNPs) in N-acetyltransferase (NAT)1, NAT2, and epoxide hydrolase (EPXH1). Associations of genotypes with RA were examined using logistic regression and gene-smoking interactions were assessed. Results There were no significant associations of any DME genotype with RA. After adjustment for multiple comparisons, there were significant additive interactions between heavy smoking and NAT2 SNPs rs9987109 (Padd = 0.000003) and rs1208 (Padd = 0.00001); attributable proportions (APs) due to interaction ranged from 0.61 to 0.67. None of the multiplicative gene-smoking interactions examined remained significant after adjustment for multiple testing in overall disease risk. There was no evidence of significant gene-smoking interactions in analyses of GSTM1-null, NAT1, or EPXH1. DME gene-smoking interactions were similar when cases were limited to anti-citrullinated protein antibody (ACPA) positive individuals. Conclusion Among African Americans, RA risk imposed by heavy smoking appears to be mediated in part by genetic variation in NAT2. While further studies are needed to elucidate mechanisms underpinning these interactions, these SNPs appear to identify African American smokers at a much higher risk for RA with relative risks that are at least two-fold higher compared to non-smokers lacking these risk alleles.

    Full Text Available Background: Psoriasis and psoriatic arthritis are common, chronic, immune mediated disease of the skin and joints. Interaction between genes and environment are important in disease causation. Objectives: The aim of the present study was to determine the socioemographic and clinical characters of adult patients with psoriasis and those with psoriatic arthritis, to define psoriasis and psoriatic arthritis etiological risk factors, and to define the relationship between psoriasis severity and these items. Subjects and methods: This study was conducted at Dermatology Clinic, Al-Hussein University Hospital. A case-control study design was chosen to perform this research. The study was conducted on 100 adult patients with psoriasis and an equal number of free adults as controls. Criteria for diagnosis of psoriasis and psoriatic arthritis were used. A comprehensive questionnaire was used to survey the studied groups. Body surface area of the affected patients was used as a marker of disease severity.Results: The study showed that 44.0% of the cases had psoriasis age of onset; 22-45 years. Stress was the most common etiological risk factor, 67.0%. While, the most important risk factors were family history of psoriasis, recurrent pharyngitis, smoking ≥20 cigarettes/ day and higher level of education, odds ratio (OR=7.58, 5.94, 2.78 and 2.69, respectively. Also, 32.0% of the patients had psoriatic arthritis. Psoriatic arthritis comes after psoriasis and had mild severity in 65.6% and 68.7% of the cases, respectively. The most important etiological risk factors were severe psoriasis, smoking ≥20 cigarettes/day and early onset of psoriasis, OR=9.64, 3.06 and 2.72, respectively.Conclusions and recommendations: The epidemiology of psoriasis is not well defined in Egypt. The heredity and environmental factors are the most important risk factors. Also, psoriatic arthritis is an important associated disease. The fact that it has no cure has important

    Full Text Available Abstract Background Health-related quality of life (HRQOL is a key outcome in arthritis, but few population-based studies have examined the relationship of specific arthritic conditions, such as osteoarthritis (OA and rheumatoid arthritis (RA with HRQOL. Methods Older adults in Pennsylvania completed a mail version of the Centers for Disease Control and Prevention (CDC HRQOL modules. Medicare data were used to identify subjects with OA, RA, and no arthritis diagnosis. We compared HRQOL responses among these groups, and we also examined relationships of demographic characteristics to HRQOL among subjects with arthritis. Results In analyses controlling for demographic characteristics and comorbidity, subjects with OA and RA had poorer scores than those without arthritis on all HRQOL items, including general health, physical health, mental health, activity limitation, pain, sleep, and feeling healthy and full of energy. HRQOL scores were also lower for those with RA compared to OA. Among individuals with arthritis, all subject characteristics (including age, race, sex, nursing home residence, marital status, income, and comorbid illnesses were significantly related to at least one HRQOL item. Older age, nursing home residence, and greater comorbidity were the most consistently associated with poorer HRQOL. Conclusions Results of this study show that both OA and RA have a significant impact on multiple dimensions of HRQOL among older adults. Results also suggest the CDC HRQOL items are suitable for use among older adults and in mail surveys. Due to the rising number of older adults in many countries, the public health burden of arthritis is expected to increase dramatically. Efforts are needed to enhance access to medical care and disseminate self-management interventions for arthritis.

    Full Text Available Abstract Background Reactive arthritis (ReA is a recognized sequela of infectious gastroenteritis (IGE. However, the population-based incidence of IGE-related ReA is poorly defined, and the risk of disease has not previously been characterized in a military population. The intent of this study was to provide estimates of the incidence and morbidity associated with IGE-related ReA in the U.S. military population. Methods Using active duty US military medical encounter data from the Defense Medical Surveillance System, we conducted a matched case-control study to assess the risk of ReA following IGE. Both specific and nonspecific case definitions were utilized to address ICD-9 coding limitations; these included specific ReA (Reiter's Disease or postdysenteric arthritis and nonspecific arthritis/arthralgia (N.A.A (which included several related arthropathy and arthralgia diagnoses. Incidence was estimated using events and the total number of active duty personnel for each year. Results 506 cases of specific ReA were identified in active duty personnel between 1999 and 2007. Another 16,365 cases of N.A.A. were identified. Overall incidence was 4.1 (95% CI: 3.7, 4.5 and 132.0 (95% CI, 130.0-134.0 per 100,000 for specific ReA and N.A.A, respectively. Compared to the youngest age category, the incidence of both outcomes increased 7-fold with a concurrent increase in symptom duration for cases over the age of 40. Specific IGE exposures were documented in 1.4% of subjects. After adjusting for potential confounders, there was a significant association between IGE and ReA (specific reactive arthritis OR: 4.42, 95% CI: 2.24, 8.73; N.A.A OR: 1.76, 95% CI: 1.49, 2.07. Conclusions Reactive arthritis may be more common in military populations than previously described. The burden of ReA and strong association with antecedent IGE warrants continued IGE prevention efforts.

  10. Risk of infection with biologic antirheumatic therapies in patients with rheumatoid arthritis.

    Science.gov (United States)

    Lahiri, Manjari; Dixon, William G

    2015-04-01

    There are currently 10 licensed biologic therapies for the treatment of rheumatoid arthritis in 2014. In this article, we review the risk of serious infection (SI) for biologic therapies. This risk has been closely studied over the last 15 years within randomised controlled trials, long-term extension studies and observational drug registers, especially for the first three antitumour necrosis factor (TNF) drugs, namely infliximab, etanercept and adalimumab. The risk of SI with the newer biologics rituximab, tocilizumab, abatacept and tofacitinib is also reviewed, although further data from long-term observational studies are awaited. Beyond all-site SI, we review the risk of tuberculosis, other opportunistic infections and herpes zoster, and the effect of screening on TB rates. Lastly, we review emerging opportunities for stratifying the risk. Patients can be risk-stratified based on both modifiable and non-modifiable patient characteristics such as age, co-morbidity, glucocorticoid use, functional status and recent previous SI.

    Full Text Available X-linked agammaglobulinemia (XLA is a primary immune deficiency characterized by recurrent bacterial infections and profoundly depressed serum immunoglobulin levels and circulating mature B cells. We describe a 12-year-old boy with XLA and enthesitis-related arthritis (ERA. To date, there has been a paucity of reports of noninfectious inflammatory arthritis in children with XLA. This case illustrates that functional B cells and/or immunoglobulin are not required for ERA pathogenesis. In addition, this case suggests a possible link between immune deficiency, immune dysregulation, and rheumatic illness.

    Background Earlier studies have demonstrated that smoking and genetic risk factors interact in providing an increased risk for Rheumatoid Arthritis (RA). Less is known on how smoking contributes to RA in the context of genetic variability, and what proportion of RA that may be caused by smoking. Objectives To determine the association between amount of smoking and risk of RA in the context of different HLA-DRB1 shared epitope (SE) alleles, and to estimate proportions of RA cases attributed to smoking. Design, Setting, and Participants Data from the Swedish Epidemiological Investigation of Rheumatoid Arthritis (EIRA) case-control study encompassing 1204 cases and 871 controls were analysed. Main Outcome Measure Estimated odds ratio to develop RA and excess fraction of cases attributable to smoking according to amount of smoking and genotype. Results Smoking was estimated to be responsible for 35 % of the ACPA+ cases. For each HLA-DRB1 SE genotype, smoking was dose-dependently associated with increased risk of ACPA+ RA (p-trend<0.001). In individuals carrying two copies of the HLA-DRB1 shared epitope, 55 % of ACPA-positive RA were attributable to smoking. Conclusions Smoking is a preventable risk factor for RA. The increased risk due to smoking is dependent on amount of smoking and genotype. PMID:21149499

    2012-04-01

    We have previously identified Cia10 as an arthritis severity and articular damage quantitative trait locus. In this study, we used Illumina RatRef-12 microarrays to analyze the expression of 21,922 genes in synovial tissues from arthritis-susceptible DA and arthritis-protected DA.ACI(Cia10) congenics with pristane-induced arthritis. 310 genes had significantly different expression. The genes upregulated in DA, and reciprocally downregulated in DA.ACI(Cia10) included IL-11, Ccl12 and Cxcl10, as well as genes implicated in Th17 responses such as IL-17A, IL-6, Ccr6, Cxcr3 and Stat4. Suppressors of immune responses Tgfb and Vdr, and inhibitors of oxidative stress were upregulated in congenics. There was an over-representation of genes implicated in cancer and cancer-related phenotypes such as tumor growth and invasion among the differentially expressed genes. Cancer-favoring genes like Ctsd, Ikbke, and Kras were expressed in increased levels in DA, whereas inhibitors of cancer phenotypes such as Timp2, Reck and Tgfbr3 were increased in DA.ACI(Cia10). These results suggest that Cia10 may control arthritis severity, synovial hyperplasia and joint damage via the regulation of the expression of cancer-related genes, inflammatory mediators and Th17-related markers. These new findings have the potential to generate new targets for therapies aimed at reducing arthritis severity and joint damage in rheumatoid arthritis. PMID:22048456

    OBJECTIVE: Patients with psoriasis and psoriatic arthritis (PsA) have an increased incidence of cardiovascular disease (CVD) and cardiovascular risk factors such as smoking, hypertension, and metabolic syndrome compared to the normal population. Patients with psoriasis and PsA may also have increased risk from nonconventional risk factors such as raised levels of homocysteine and excessive alcohol consumption. We conducted a comprehensive review of the literature on CVD and all cardiovascular risk factors in patients with psoriasis and PsA. METHODS: Data sources: All studies identified from a Medline (www.ncbi.nlm.nih.gov) search pertaining to CVD, individual risk factors in psoriasis, and PsA were included. Study selection: Studies included a healthy reference population, were published between 1975 and 2009, and were written in English. RESULTS: Our search yielded 14 studies that documented rates of CVD in patients with psoriasis and PsA compared to controls. Substantial evidence points to elevated risk of CVD in patients with psoriasis and PsA. CONCLUSION: It remains difficult to conclude if risk factors are caused by psoriasis or share a common pathogenesis. Physicians treating patients with psoriasis and PsA must be aware of all potential cardiovascular risk factors in their patients.

    Rheumatoid arthritis (RA) is a complex genetic disease. Human leukocyte antigen (HLA) and non-HLA genes are reportedly associated with an increased risk of RA. The protein tyrosine phosphatase non-receptor 22 gene (PTPN22), which encodes the lymphoid tyrosine phosphatase (LYP) protein, is one of the best examples of a non-HLA gene associated with a risk for RA in several populations. The functional PTPN22 C1858T (R620W) non-synonymous polymorphism is widely associated with an increased risk for RA in Europeans and non-Europeans. The aim of this study was to determine if the PTPN22 C1858T polymorphism confers susceptibility to RA in a sample of patients from Mexico. This study included 364 RA patients and 387 non-related controls from Central Mexico. Genotyping of the PTPN22 C1858T (rs2476601) polymorphism was performed using allelic discrimination assays with TaqMan probes. The functional PTPN22 C1858T polymorphism was associated with an increased risk for RA in our study population. The CC vs CT genotype in RA patients versus healthy controls had an odds ratio (OR) of 4.17 (95 % CI 1.79-9.74, p = 0.00036), while T allele had an OR of 4.06 (95 % CI 1.75-9.41, p = 0.00043). PTPN22 is a genetic risk factor for developing RA in the Mexican population. PMID:26951256

    A 71-year-old man with osteoarthritis and chondrocalcinosis came to our observation developing a swelling in the groin region after a recent left colectomy for adenocarcinoma. The imaging techniques revealed the presence of an iliopsoas bursitis in connection with the hip. The synovial fluid analysis detected the presence of calcium pyrophosphate (CPP) crystals and allowed the final and unusual diagnosis of iliopsoas bursitis related to acute CPP crystal hip arthritis.

    Full Text Available The study was aimed to evaluate cardiovascular risk parameters, body mass index (BMI centiles for sex and age, and body fat percentage using the electric bioimpedance method in children with juvenile idiopathic arthritis (JIA. 30 children with JIA participated in the study. A control group included 20 children. Patients were well matched for the age and sex. The body mass and body fat percentage were determined using the segmental body composition analyser; the BMI centiles were determined. All patients had the following parameters determined: lipid profile, hsCRP, homocysteine, and IL-6. The intima media thickness (IMT was measured. Patients with JIA had significantly lower body weight, BMI, and the BMI centile compared to the control group. The IL-6 levels were significantly higher in patients with JIA compared to the control group. There were no differences between two groups with regard to the lipid profile, % content of the fat tissue, homocysteine levels, hsCRP, and IMT. Further studies are necessary to search for reasons for lower BMI and BMI centile in children with JIA and to attempt to answer the question of whether lower BMI increases the cardiovascular risk in these patients, similarly as in patients with rheumatoid arthritis (RA.

    Full Text Available BACKGROUND: To investigate the associations between HLA-DRB1 shared epitope (SE alleles and rheumatoid arthritis in subsets of rheumatoid arthritis defined by autoantibodies in three Asian populations from Malaysia. METHODS: 1,079 rheumatoid arthritis patients and 1,470 healthy controls were included in the study. Levels of antibodies to citrullinated proteins (ACPA and rheumatoid factors were assessed and the PCR-SSO method was used for HLA-DRB1 genotyping. RESULTS: The proportion of ACPA positivity among Malay, Chinese and Indian rheumatoid arthritis patients were 62.9%, 65.2% and 68.6%, respectively. An increased frequency of SE alleles was observed in ACPA-positive rheumatoid arthritis among the three Asian ethnic groups. HLA-DRB1*10 was highly associated with rheumatoid arthritis susceptibility in these Asian populations. HLA-DRB1*0405 was significantly associated with susceptibility to rheumatoid arthritis in Malays and Chinese, but not in Indians. HLA-DRB1*01 did not show any independent effect as a risk factor for rheumatoid arthritis in this study and HLA-DRB1*1202 was protective in Malays and Chinese. There was no association between SE alleles and ACPA- negative rheumatoid arthritis in any of the three Asian ethnic groups. CONCLUSION: The HLA-DRB1 SE alleles increase the risk of ACPA-positive rheumatoid arthritis in all three Asian populations from Malaysia.

    2011-06-01

    There is great interest in the identification of genetic factors that differentiate psoriatic arthritis (PsA) from psoriasis vulgaris (PsV), as such discoveries could lead to the identification of distinct underlying aetiological pathways. Recent studies identified single nucleotide polymorphisms (SNPs) in the interleukin 13 (IL-13) gene region as risk factors for PsV. Further investigations in one of these studies found the effect to be primarily restricted to PsA, thus suggesting the discovery of a specific genetic risk factor for PsA. Given this intriguing evidence, association to this gene was investigated in large collections of PsA and PsV patients and healthy controls.

    The current methods of cardiovascular (CV) risk assessment in the course of inflammatory connective tissue diseases are a subject of considerable controversy. Comparing different methods of CV risk assessment in current rheumatoid arthritis (RA) guidelines, only a few of them recommend the use of formal risk calculators. These are the EULAR guidelines suggesting the use of SCORE and the British Society for Rheumatology guidelines performed in collaboration with NICE preferring the use of QRISK-2. Analyzing the latest American and British reports, two main concepts could be identified. The first one is to focus on risk calculators developed for the general population taking into account RA, and the calculator that might fulfill this role is the new QRISK-2 presented by NICE in 2014. The second concept is to create RA-specific risk calculators, such as the Expanded Cardiovascular Risk Prediction Score for RA. In this review we also discuss the efficiency of a new Pooled Cohort Equation and other calculators in the general and RA population. PMID:27504023

    Rheumatoid arthritis (RA) is a chronic inflammatory disease which is associated with an increased cardiovascular (CV) burden. Whether the risk is already present at the time of RA diagnosis remains a key area of debate. The aim of this review was to evaluate the existence of both subclinical CV changes, including endothelial dysfunction and atherosclerosis, CV risk factors, as well as CV disease manifestations such as coronary heart disease, myocardial infarction, congestive heart failure and CV death prior to RA diagnosis and during the first few years of the disease. The state of the endothelial function remains controversial in patients with newly diagnosed RA. Studies with impaired brachial artery vasodilatory responses at baseline showed a reversal of the dysfunction after 6-12 months of anti-inflammatory therapy. Morphological evidence of arterial wall atherosclerosis, measured by carotid artery intima-media thickness or the prevalence of carotid plaques, was already present during the first year following RA diagnosis. The risk of coronary heart disease and myocardial infarction is increased even prior to and, at the latest, within 1 year of the clinical onset of RA. The prevalence of hypertension was similar among patients with RA and controls. CV mortality may not increase within the first years of RA diagnosis. In conclusion, the CV risk seems to increase sooner after the RA diagnosis than previously thought. In addition to systematic CV risk assessment, patients with early RA might benefit from being targeted with stricter than conventional CV risk prevention and intervention. PMID:22736093

    Rheumatoid arthritis (RA) is a chronic inflammatory disease in which the progressive destruction of joint causes morbidity. It is also associated with an increased risk of atherosclerosis, which can result in cardiovascular disease and mortality. The therapeutic goal is to control the systemic inflammation to obtain not only the remission of symptoms, but also improve general state of health. Although recent biologic immunosuppressive therapies targeting pro-inflammatory cytokines have spawned a paradigm shift regarding the prognosis of RA, these therapies possess inherent side effects. Also, early diagnosis of the disease remains confounded by uncertainty. While the mechanisms responsible for the onset of RA remain unclear, reactive oxygen species (ROS) play a significant role in the pathogenesis of RA. ROS play a central role both upstream and downstream of NF-κB and TNFα pathways, which are located at the center of the inflammatory response. Among the ROS, the hydroxyl radical is the most harmful, and molecular hydrogen (H2) is a selective scavenger for this species. Recently, it has been shown that H2 is useful when administered along with the conventional therapy in RA as it acts to reduce oxidative stress in the patients. Especially in the early stage, H2 showed significant therapeutic potential, which also seemed to assist diagnosis and treatment decisions of RA. The possible expectations regarding the potential benefits of H2 by reducing the oxidative stress, resulting from inflammatory factors, are raised and discussed here. They include prevention of RA and related atherosclerosis, as well as therapeutic validity for RA. PMID:23859555

    Full Text Available The use of tumor necrosis factor-α (TNF-α inhibitors that selectively block important components of the immunopathogenesis of rheumatoid arthritis (RA is a highly effective and relatively safe treatment for rheumatoid inflammation and can be considered as a new area in the therapy of autoimmune diseases, the basis of which is T- and B-cell immunity suppression. At the same time, it is necessary to conduct prospective studies that will be able to more exactly define the implication of TNF-α in the development of cardiovascular catastrophes and its inhibition in the prevention of cardiovascular events in patients with RA.

    The improved characterisation of risk factors for rheumatoid arthritis (RA) suggests they could be combined to identify individuals at increased disease risks in whom preventive strategies may be evaluated. We aimed to develop an RA prediction model capable of generating clinically relevant predictive data and to determine if it better predicted younger onset RA (YORA). Our novel modelling approach combined odds ratios for 15 four-digit/10 two-digit HLA-DRB1 alleles, 31 single nucleotide polymorphisms (SNPs) and ever-smoking status in males to determine risk using computer simulation and confidence interval based risk categorisation. Only males were evaluated in our models incorporating smoking as ever-smoking is a significant risk factor for RA in men but not women. We developed multiple models to evaluate each risk factor's impact on prediction. Each model's ability to discriminate anti-citrullinated protein antibody (ACPA)-positive RA from controls was evaluated in two cohorts: Wellcome Trust Case Control Consortium (WTCCC: 1,516 cases; 1,647 controls); UK RA Genetics Group Consortium (UKRAGG: 2,623 cases; 1,500 controls). HLA and smoking provided strongest prediction with good discrimination evidenced by an HLA-smoking model area under the curve (AUC) value of 0.813 in both WTCCC and UKRAGG. SNPs provided minimal prediction (AUC 0.660 WTCCC/0.617 UKRAGG). Whilst high individual risks were identified, with some cases having estimated lifetime risks of 86%, only a minority overall had substantially increased odds for RA. High risks from the HLA model were associated with YORA (P<0.0001); ever-smoking associated with older onset disease. This latter finding suggests smoking's impact on RA risk manifests later in life. Our modelling demonstrates that combining risk factors provides clinically informative RA prediction; additionally HLA and smoking status can be used to predict the risk of younger and older onset RA, respectively.

    Gut microflora and dysbiosis as an environmental factor has been linked to the pathogenesis of enthesitis-related arthritis (JIA-ERA); thus, we performed a proof-of-concept study of probiotics to modulate the gut-flora and study the effects on immune and clinical parameters of children having JIA-ERA. Forty-six children with active JIA-ERA were randomized to placebo or probiotic therapy along with non-steroidal anti-inflammatory drugs (NSAIDs) for 12 weeks. Patients were assessed using a six-point composite disease activity index (mJSpADA) based on morning stiffness, joint count, enthesitis count, sacroiliitis/inflammatory back pain, uveitis and erythrocyte sedimentation rate/C-reactive protein (ESR/CRP). Frequencies of T helper type 1 (Th1), Th2, Th17 and regulatory T cells in blood were measured using flow cytometry. Serum cytokines interferon (IFN)-γ, interleukin (IL)-4, IL-17, IL-10, tumour necrosis factor (TNF)-α and IL-6 were measured by cytokine bead array using flow cytometer. The average age of 46 children (44 boys) was 15 ± 2.5 years and duration of disease was 3.5 ± 3 years. There was no significant difference in improvement in mJSpADA between the two groups (P = 0·16). Serum IL-6 levels showed a decrease (P < 0·05) in the probiotic-group. Th2 cell frequency (P < 0·05) and serum IL-10 levels (P < 0·01) showed an increase in the placebo group, but again the probiotic use did not show a significant change in immune parameters when compared to the placebo. Adverse effects among the probiotic and placebo groups were diarrhea (36 versus 45%), abdominal pain (9 versus 20%), minor infections (4·5 versus 20%) and flatulence (23 versus 15%), respectively. Thus, we can conclude that probiotic therapy in JIA-ERA children is well tolerated, but failed to show any significant immune or clinical effects over NSAID therapy. PMID:27238895

    To assess the impact of the application of the European League against Rheumatism (EULAR) task force recommendations in the cardiovascular (CV) risk of a series of Spanish patients diagnosed with rheumatoid arthritis (RA). Two hundred consecutive RA patients seen at the rheumatology outpatient clinics of Bellvitge Hospital, Barcelona, were studied. Information on clinical features of the disease, classic CV risk factors, and history of CV events was assessed. Both the systematic coronary risk evaluation (SCORE) CV risk index and the modified SCORE (mSCORE) according to the last EULAR recommendations were calculated. Based on the classic CV risk factors, the mean ± standard deviation SCORE was 2.1 ± 2.3% (median, 2; interquartile range [IQR], 1-3). Twenty-three (11%) patients were above the threshold of high CV risk for the Spanish population (≥5%). Following the EULAR recommendations, a change in the score was required in 119 (59%) patients. Therefore, the mean mSCORE was 2.7 ± 2.9% (median, 2; IQR, 1-3) and, due to this, 28 (14%) patients were above the threshold of high CV risk. Nine (5%) had at least one ischemic CV event. Patients with CV events were older and had more CV risk factors and higher SCORE and mSCORE than those without CV events. Although a large proportion of patients from this series fulfilled the criteria for the application of the EULAR recommendations, the final impact on the calculated CV risk was low and clinically significant in only a few patients. However, an association between the mSCORE and the presence of ischemic CV events was observed. PMID:21567119

    Reactive arthritis is an important cause of lower limb oligoarthritis, mainly in young adults. It is one of the spondyloarthropathy family; it is distinguishable from other forms of inflammatory arthritis by virtue of the distribution of affected sites and the high prevalence of characteristic extra‐articular lesions. Many terms have been used to refer to this and related forms of arthritis leading to some confusion. Reactive arthritis is precipitated by an infection at a distant site and gen...

Anna Hospital, Brescia, Italy; 3Eye Clinic, Department of Health Sciences, University of Molise, Campobasso, ItalyAbstract: Juvenile idiopathic arthritis-related uveitis is the most common type of uveitis in childhood and one of the main causes of visual impairment in children. The introduction of biological treatment has widened the range of therapeutic options for children with uveitis refractory to standard nonbiologic immunosuppressants. Data from clinical trials suggest that both adalimumab and infliximab have demonstrated effectiveness and safety in open-label studies, although no large, randomized, controlled trials have been reported so far. The role of etanercept in treating juvenile idiopathic arthritis-related uveitis is not yet well defined. In our experience, anti-tumor necrosis factor therapy has been shown to be more effective than steroids and/or methotrexate in treating uveitis. Up to now, tumor necrosis factor blocking compounds have been reserved for the treatment of the most severe cases of refractory uveitis, and larger prospective clinical trials are required in order to better assess the safety of these new compounds.Keywords: adalimumab, etanercept, infliximab

    HLA phenotypes were determined in 50 patients with psoriasis alone and in 50 patients with psoriasis and psoriatic arthritis. Positive associations were found in both groups with B13, B17, B37, Cw6, and DR7, and in addition with C4A6. Higher relative risks were found in respect to the patients with psoriasis alone compared with those with arthritis, and this suggests the involvement of additional genetic factors predisposing to peripheral arthritis.

    Full Text Available Objective: Rheumatoid arthritis (RA is a chronic autoimmune inflammatory disorder of flexible joints with unknown etiology, which affects 1% of the world’s population. The aim of this 2010 study was to investigate the association between the level of education, tonsillectomy and appendectomy in the patients’ history with RA. The study was carried out in Hamedan City, in the West of Iran.Patients and Methods: As a patient-control study, information from 128 patients and 130 controls, matched for age and gender, was collected by questionnaires and physical exams with the consent of both patients and controls, followed by an SPSS statistical analysis (Pearson’s Chi-Square test.Results: In patient and control groups, there were 116 and 117 females, respectively, and the rest were males. Statistical analysis showed that there is no significant association between level of education or tonsillectomy with RA (p>0.05, whereas appendectomy was significantly associated inversely with the risk of RA (p < 0.05.Conclusion: Considering previous global investigations on this topic with different results and the results of our study, it seems that more studies are needed to determine the definitive association between level of education, tonsillectomy and appendectomy with the risk of RA.

    Chih-Chao Hsu

    Full Text Available Studies have suggested that chronic inflammation plays an essential role in the pathophysiology of both rheumatoid arthritis (RA and bipolar disorder. The most common clinical features associated with RA are anxiety and depression. The risk of bipolar disorder among patients with RA has not been characterized adequately.To determine the association between RA and the subsequent development of bipolar disorder and examine the risk factors for bipolar disorder among patients with RA.We identified patients who were diagnosed with RA in the Taiwan National Health Insurance Research Database. A comparison cohort was created by matching patients without RA with those with RA according to age, sex, and comorbidities. The occurrence of bipolar disorder was evaluated in both cohorts.The RA cohort consisted of 2,570 patients, and the comparison cohort consisted of 2,570 matched control patients without RA. The incidence of bipolar disorder (incidence rate ratio  = 2.13, 95% confidence interval [CI]  = 1.12-4.24, P =  .013 was higher among patients with RA than among control patients. Multivariate, matched regression models revealed that asthma (hazard ratio [HR]  = 2.76, 95% CI 1.27-5.96, P =  .010, liver cirrhosis (HR  = 3.81, 95% CI  = 1.04-14.02, P =  .044, and alcohol use disorders (HR  = 5.29, 95% CI  = 1.71-16.37, P =  .004 were independent risk factors for the development of bipolar disorder among patients with RA.RA might increase the incidence of bipolar disorder development. Based on our data, we suggest that, following RA diagnosis, greater attention be focused on women with asthma, liver cirrhosis, and alcohol use disorder. Prospective clinical studies of the relationship between RA and bipolar disorder are warranted.

    Objective The relationship between chronic inflammation and the incidence of chronic kidney disease (CKD) remained not-clear in patients with rheumatoid arthritis (RA). This study aims to examine the relationship between persistently high C-reactive protein (CRP), a marker of inflammation, and the incidence of CKD in RA. Methods We retrospectively examined the relationship between the levels of CRP and incidence of CKD in 345 RA patients. The outcome of interest was incidence of CKD, defined as an estimated glomerular filtration rate (eGFR) CRP, as >3.0 mg/L. On the basis of three measurements of CRP for 6-months period, patients were divided into three groups: group 1, including patients with no high CRP values; group 2, patients with transient high CRP values (once or twice) and group 3, patients with persistently high CRP values. Results During a median follow-up period of 89 months, 14% of all patients developed CKD. The cumulative incidence of CKD was 7% in group 1, 14% in group 2 and 22% in group 3 (P = 0.008, log-rank test). In a multivariate analysis, including classical risk factors for CKD, persistently high CRP was an independent predictor of the incidence of CKD (hazard ratio, 3.00; 95% confidence interval, 1.23–8.53; P = 0.01). Conclusions Persistently high CRP was a significant risk factor for the incidence of CKD. Results suggest that persistent inflammation is a marker for the high risk of CKD in RA. PMID:27537204

    Full Text Available Abstract Background Bisphosphonate-related osteonecrosis of the jaw (BRONJ is a clinical condition characterized by the presence of exposed bone in the maxillofacial region. Its pathogenesis is still undetermined, but may be associated with risk factors such as rheumatoid arthritis (RA. The aim of this paper is to report two unpublished cases of BRONJ in patients with RA and to conduct a literature review of similar clinical cases with a view to describe the main issues concerning these patients, including demographic characteristics and therapeutic approaches applied. Methods Two case reports of BRONJ involving RA patients were discussed Results Both patients were aging female taking alendronate for more than 3 years. Lesions were detected in stage II in posterior mandible with no clear trigger agent. The treatment applied consisted of antibiotics, oral rinses with chlorhexidine, drug discontinuation and surgical procedures. Complete healing of the lesions was achieved. Conclusions This paper brings to light the necessity for rheumatologists to be aware of the potential risk to their patients of developing BRONJ and to work together with dentists for the prevention and early detection of the lesions. Although some features seem to link RA with oral BRONJ and act as synergistic effects, more studies should be developed to support the scientific bases for this hypothesis.

    STAT4 has been consistently associated with several autoimmune diseases, including rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). The aim of this study was to determine whether the STAT4 rs7574865G/T polymorphism confers susceptibility for RA and SLE in a sample of Mexican patients. This study included 869 individuals: 415 patients with RA, 128 patients with SLE, and 326 controls. Genotyping using TaqMan probes showed an association between the STAT4 rs7574865G/T polymorphism and RA (GG vs. TT: OR 1.99, p=0.0009; G vs. T: OR 1.42, p=0.0009) and SLE (GG vs. TT: OR 2.98, 0.0003; G vs. T: OR 1.74, p=0.0002). Gender stratification showed an association with RA (GG vs. TT: OR 1.99, 95% CI 1.3-3.1, p=0.002; G vs. T: OR 1.42, 95% CI 1.1-1.8, p=0.002) and SLE (GG vs. TT: OR 3.3, 95% CI 1.7-6.2, p=0.0002; G vs. T: OR 1.8, 95% CI 1.3-2.4, p=0.0002) in women. Thus, the STAT4 rs7574865G/T polymorphism confers risk for RA and SLE in the Mexican population. PMID:27178308

  15. Hypermethylation of MST1 in IgG4-related autoimmune pancreatitis and rheumatoid arthritis

    International Nuclear Information System (INIS)

    The serine/threonine kinase Mst1 plays important roles in the control of immune cell trafficking, proliferation, and differentiation. Previously, we reported that Mst1 was required for thymocyte selection and regulatory T-cell functions, thereby the prevention of autoimmunity in mice. In humans, MST1 null mutations cause T-cell immunodeficiency and hypergammaglobulinemia with autoantibody production. RASSF5C(RAPL) is an activator of MST1 and it is frequently methylated in some tumors. Herein, we investigated methylation of the promoter regions of MST1 and RASSF5C(RAPL) in leukocytes from patients with IgG4-related autoimmune pancreatitis (AIP) and rheumatoid arthritis (RA). Increased number of CpG methylation in the 5′ region of MST1 was detected in AIP patients with extrapancreatic lesions, whereas AIP patients without extrapancreatic lesions were similar to controls. In RA patients, we detected a slight increased CpG methylation in MST1, although the overall number of methylation sites was lower than that of AIP patients with extrapancreatic lesions. There were no significant changes of the methylation levels of the CpG islands in the 5′ region of RASSF5C(RAPL) in leukocytes from AIP and RA patients. Consistently, we found a significantly down-regulated expression of MST1 in regulatory T cells of AIP patients. Our results suggest that the decreased expression of MST1 in regulatory T cells due to hypermethylation of the promoter contributes to the pathogenesis of IgG4-related AIP. - Highlights: • Mst1 controls immune cells trafficking, cell proliferation and differentiation. • Autoimmune pancreatitis (AIP) is an idiopathic pancreatitis affecting multiple organs. • Decreased MST1 expression and increased CpG methylation of promoter of MST1 in AIP. • Slight increased CpG methylation of MST1 in rheumatoid arthritis patients. • MST1 contributes pathogenesis of IgG4-related AIP

    Guillaume Moulis

    Full Text Available BACKGROUND: The risk of malignancies on TNF-α antagonists is controversial. The aim of this survey was to assess cancer risk on TNF-α antagonists in adult rheumatoid arthritis patients, including the five marketed drugs (infliximab, etanercept, adalimumab, golimumab and certolizumab used in line with the New Drug Application. Furthermore, the relative interest of modified intention to treat or per protocol analyses to assess such sparse events remains unknown. METHODOLOGY/PRINCIPAL FINDINGS: Data sources were MEDLINE, CENTRAL, ISI Web of Science, ACR and EULAR meeting abstracts, scientific evaluation of the drugs leading to their marketing approval, and clinicaltrials.gov, until 31 December 2012.We selected double-blind randomized controlled trials in adult rheumatoid arthritis patients, including at least one treatment arm in line with New Drug Application. We performed random effect meta-analysis, with modified intention to treat and per protocol analyses. Thirty-three trials were included. There was no excess risk of malignancies on anti-TNF-α administered in line with New Drug Application in the per protocol model (OR, 0.93 95%CI[0.59-1.44], as well as in the modified intention to treat model (OR, 1.27 95%CI[0.82-1.98]. There was a non-significant tendency for an excess non-melanoma skin cancer risk in both models (respectively, 1.37 [0.71-2.66] and 1.90 [0.98-3.67]. With fixed effect Peto model restricting to trials during at least 52 weeks, the overall cancer risk was respectively 1.60 [0.97-2.64] and 1.22 [0.72-2.08]. Whatever the model, modified intention to treat analysis led to higher estimations than per protocol analysis. The later may underestimate the treatment effect when assessing very sparse events and when many patients dropped out in placebo arms. In metaregression, there was no differential risk among the five drugs. CONCLUSIONS/SIGNIFICANCE: This study did not find any evidence for an excess cancer risk on TNF

    Objective Findings from previous studies have suggested that subclinical inflammation of the synovium does not coincide with the appearance of rheumatoid arthritis (RA)–specific autoantibodies. This study was undertaken to examine the relationship between the presence of autoantibodies, changes in the synovium, and development of arthritis over time in a markedly larger, prospective study. Methods Fifty-five individuals who were IgM rheumatoid factor positive and/or anti–citrullinated protein antibody (ACPA) positive (detected by the anti–cyclic citrullinated peptide antibody test) and who were without any evidence of arthritis upon physical examination were included in the study. ACPAs were subsequently also detected using a multiplex chip-based assay. All individuals underwent magnetic resonance imaging and mini-arthroscopic synovial biopsy sampling of a knee joint at inclusion and were prospectively followed up. Proportional hazards regression analysis was performed to investigate whether changes in the synovium were associated with the onset of arthritis. Results Fifteen individuals (27%) developed arthritis after a median followup time of 13 months (interquartile range 6–27 months; range 1–47 months). No overt synovial inflammation was observed, but CD3+ T cell numbers in the biopsy tissue showed a borderline association with subsequent development of clinically manifest arthritis (hazard ratio 2.8, 95% confidence interval [95% CI] 0.9–9.1; P = 0.088). In addition, the presence of CD8+ T cells was associated with ACPA positivity (odds ratio [OR] 16.0, 95% CI 1.7–151.1) and with the total number of ACPAs present (OR 1.4, 95% CI 1.0–1.8). Conclusion These findings confirm and extend previous results showing the absence of clearcut synovial inflammation in individuals having systemic autoimmunity associated with RA. However, subtle infiltration by synovial T cells may precede the signs and symptoms of arthritis in preclinical RA. PMID:24574210

    Full Text Available Abstract Background An inverse association between early contact with microbial compounds and respiratory allergies is well established. The protective effect of infant contact with animals was also shown for inflammatory bowel disease (IBD and systemic lupus erythematosus (SLE. We aimed to test the association between animal contact in infancy and oligoarticular juvenile idiopathic arthritis (OA JIA. Methods Parents of children with OA JIA registered at the Hospital for Pediatric Rheumatology in Garmisch-Partenkirchen were asked to complete a questionnaire. Children who underwent strabismus surgery at six referral centers for ophthalmology served as controls. Children age 6 to 18 years born in Germany without malformations were included (238 cases; response 89% and 832 controls; response 86%. Data were analyzed using logistic regression models after adjusting for potential confounders. Results Neither place of living (urban vs. rural area, living on a farm, nor regular farm animal (adjusted odds ratio 0.79; 95% confidence interval 0.42-1.47 or pet contact (0.79; 0.55-1.14 during infancy were clearly related to case status. Allergic rhinitis was inversely related to OA JIA (0.57; 0.34-0.95. Neither place of living (urban vs. rural area, living on a farm, nor regular farm animal (adjusted odds ratio 0.79; 95% confidence interval 0.42-1.47 or pet contact (0.79; 0.55-1.14 during infancy were related to case status. Allergic rhinitis was inversely related to OA JIA (0.57; 0.34-0.95. Conclusions Contact with farm environments in infancy might not be associated with OA JIA. This finding is consistent with previous findings for diabetes mellitus type 1 but contradicts results for IBD and SLE.

      Biologics have revolutionized the treatment of rheumatoid arthritis (RA). However certain amount of the patients cannot achieve goal of therapy. Recently, compounds targeting the intracellular kinase, Janus kinase (JAK) have demonstrated therapeutic effects resembling biologics. Tofacitinib is the only JAK inhibitor approved for RA and during the clinical trial, increased events of herpes zoster (HZ) was observed. Incidence rate was twice as much as patients treated with conventional anti-rheumatic drug and was especially increased in Japan that was four times as much. The risk factors were age and glucocorticoid that is identical to that of common RA patients and there was nothing specific for tofacitinib. Mechanism of increased incidence of HZ and the difference in ethnicity remains unknown. Analysis of clinical trials have identified that HZ do not correlate with further adverse events. Therefore, it is extremely important to accumulate clinical data with considerable amount of patients with long term follow up including the post marketing surveillance in Japan to reveal the significance of increased HZ in RA patients.

    If the diagnosis of the hip septic arthritis is delayed, serious complications such as the arthrosis in joint, the separation of epiphyseal, osteomyelitis and sepsis can develop. The presence of the accompanying infectious diseases contributes to the delay of the diagnosis. In order to get rid of the late period sequelaes of septic arthritis, the required tests should be asked for the differential diagnosis of this disease in each patient presenting with hip pain.

    This study was conducted to investigate the predictive value of the initial response to methotrexate (MTX) on long-term patient-related outcomes (PROs) in rheumatoid arthritis (RA). All RA patients starting MTX treatment between 1980 and 1987 in our department were enrolled in a prospective observational study. After an average of 18 years, patient-related outcomes were assessed in three dimensions according to the International Classification of Functioning, Disability and Health (ICF). Statistical analyses employed multivariable models with baseline values for age, gender, disease duration, rheumatoid factor positivity, disease activity, response to MTX after 1 year and continuous use of MTX as covariates. The 271 patients enrolled had a mean disease duration of 8.5 years, a mean number of swollen joints of 18 (out of 32), and a mean erythrocyte sedimentation rate of 55 mm/h. After 18 years, PRO was available in 89 patients (33 %). A clinical improvement of at least 20 % 1 year after the initiation of MTX was associated with a favourable outcome in all three dimensions of the ICF, independent of continuation of MTX (p < 0.05). The initial response to MTX is an independent predictor of PRO in RA as assessed after an average of 18 years. PMID:26920753

    Full Text Available Abstract Background The health-related quality of life (HRQL is an important indicator of the burden of musculoskeletal disease. The Medical Outcome Study Short-Term 36 (SF-36 is the most used tool that evaluates HRQL as a subjective perception about psychological and physical limitations due to an underlying illness. The purpose of this study was to compare the HRQL scores among patients with rheumatoid arthritis (RA, psoriatic arthritis (PsA and ankylosing spondylitis (AS and a selected sample of health people and determine their relationship with measures of clinical condition. Methods 799 patients (469 with RA, 164 with AS, 65 with axial PsA and 101 with peripheral PsA accepted the invitation to participate. 1579 healthy controls were used for the comparison. We calculated scores for the eight SF-36 subscales, the Physical Component Summary (PCS score, and the Mental Component Summary (MCS score, according to published algorithms. Disease-related characteristics included disease duration, comorbidity, a measure for disease activity and for radiographic damage. The presence of comorbidity was ascertained through patient's self-reports by the Self-Administered Comorbidity Questionnaire (SCQ. Comparison were performed with respect to sex and age, and s-scores were calculated for comparison with the norm. Multivariate analyses were used to assess the relationship between HRQL and radiographic damage, disease activity, and socio-demographic data. Results The four inflammatory rheumatic diseases (IRD, compared to controls, significantly impaired all eight health concepts of the SF-36 (p Conclusion Chronic IRD have a clearly detrimental effect on the HRQL in both sex and in age groups, and physical domain is more impaired than mental and social ones.

  10. LDL cholesterolemia as a novel risk factor for radiographic progression of rheumatoid arthritis: a single-center prospective study.

    Directory of Open Access Journals (Sweden)

    Yune-Jung Park

    Full Text Available Dyslipidemia has been implicated in various musculoskeletal diseases, including rheumatoid arthritis (RA. Evidence is emerging that there might be a pathogenic interaction among inflammation, dyslipidemia, and adipokines. We prospectively investigated the association of cumulative lipid levels with radiographic progression of RA. RA patients (n=242 underwent plasma cholesterol assessment at four visits. Disease activity parameters and X-rays of the hands and feet were also serially monitored in these patients. The cumulative inflammatory burden and lipid levels were estimated by time-integrated values. Serum leptin and adiponectin concentrations were determined by ELISA. When patients were divided into three groups according to time-integrated lipid levels, as expected, patients with LDL cholesterol and/or triglyceride levels in the third tertile had persistently higher ESR and CRP levels. In parallel, a more rapid radiographic progression over two years was observed in patients with higher LDL cholesterol and/or triglyceride levels. In multivariate analysis, time-integrated LDL cholesterol was independently associated with radiographic progression. Particularly, the risk of radiographic progression was 5.6-fold in a subgroup with both LDL cholesterol and triglyceride levels in the third tertile. Moreover, LDL cholesterol synergistically increased the adjusted probability of radiographic progression in patients with high serum leptin levels but not in those without. These results demonstrate that LDL cholesterolemia is a novel serum marker that can be used to predict radiographic progression of RA, which seems to be related to circulatory leptin levels. We suggest that personalized and more aggressive anti-rheumatic therapy is required for dyslipidemic subgroups in RA patients.

  11. When is arthritis reactive?

    Science.gov (United States)

    Hamdulay, S S; Glynne, S J; Keat, A

    2006-07-01

    Reactive arthritis is an important cause of lower limb oligoarthritis, mainly in young adults. It is one of the spondyloarthropathy family; it is distinguishable from other forms of inflammatory arthritis by virtue of the distribution of affected sites and the high prevalence of characteristic extra-articular lesions. Many terms have been used to refer to this and related forms of arthritis leading to some confusion. Reactive arthritis is precipitated by an infection at a distant site and genetic susceptibility is marked by possession of the HLA-B27 gene, although the mechanism remains uncertain. Diagnosis is a two stage process and requires demonstration of a temporal link with a recognised "trigger" infection. The identification and management of "sexually acquired" and "enteric" forms of reactive arthritis are considered. Putative links with HIV infection are also discussed. The clinical features, approach to investigation, diagnosis, and management of reactive arthritis are reviewed. PMID:16822921

  12. Respiratory symptoms in rheumatoid arthritis. Relation between high resolution CT findings and functional impairment

    International Nuclear Information System (INIS)

    The objectives of this study were to analyze the high resolution computed tomography (HRCT) findings in rheumatoid arthritis (RA) patients with respiratory symptoms and to evaluate the relation between the extent of HRCT findings and functional impairment as assessed by spirometry. HRCT examination of the thorax and pulmonary function tests (PFTs) were performed in 34 RA patients with respiratory symptoms. Patients with smoking history or with emphysema evident on HRCT were excluded from the study. CT findings were assessed for the presence and pattern of abnormalities. Extent was scored based on the number of pulmonary segments involved. PFTs included forced expiratory flows (FEFs) and forced vital capacity (FVC). Bronchial wall thickening was detected in 29 of 34 RA patients (85%), small nodules in 24 patients (71%), and bronchial dilatation in 21 patients (62%). The extent of bronchial wall thickening correlated with FEF25-75, FEF75, and FEF50 (p<0.0001, respectively) (Spearman's rank correlation). Extent of small nodules correlated with FEF25-75, FEF50, and FEF25 (p<0.01, respectively). Stepwise regression analysis showed independent correlations of bronchial wall thickening with decreases in FEF25-75 and FEF75 (p<0.0001, both). Bronchial dilatation was also independently associated with a decrease in FVC (p<0.05). The most common HRCT findings in RA patients with respiratory symptoms are bronchial wall thickening and small nodules, and the extent of these findings correlates significantly with functional impairment.

    Full Text Available Abstract Background Patients with rheumatoid arthritis (RA are known to be at increased risk of infection, particularly if they are taking drugs with immunomodulatory effects. There is a need for more information on the risk of influenza in patients with RA. Methods A retrospective cohort study was carried out using data gathered from a large US commercial health insurance database (Thomson Reuters Medstat MarketScan from 1 January 2000 to 31 December 2007. Patients were ≥18 years of age, with at least two RA claims diagnoses. The database was scanned for incidence of seasonal influenza and its complications on or up to 30 days after an influenza diagnosis in RA patients and matched controls. Other factors accounted for included medical conditions, use of disease-modifying anti-rheumatic drugs (DMARDs, use of biological agents, influenza vaccination and high- or low-dose corticosteroids. Incidence rate ratios (IRRs were calculated for influenza and its complications in patients with RA. Results 46,030 patients with RA and a matching number of controls had a median age of 57 years. The incidence of influenza was higher in RA patients than in controls (409.33 vs 306.12 cases per 100,000 patient-years, and there was a 2.75-fold increase in incidence of complications in RA. Presence or absence of DMARDs or biologics had no significant effect. The adjusted IRR of influenza was statistically significant in patients aged 60–69 years, and especially among men. A significantly increased rate of influenza complications was observed in women and in both genders combined (but not in men only when all age groups were combined. In general, the risk of influenza complications was similar in RA patients not receiving DMARDs or biologics to that in all RA patients. Pneumonia rates were significantly higher in women with RA. Rates of stroke/myocardial infarction (MI were higher in men, although statistical significance was borderline. Conclusions RA is

    Full Text Available Abstract Juvenile arthritis comprises a variety of chronic inflammatory diseases causing erosive arthritis in children, often progressing to disability. These children experience functional impairment due to joint and back pain, heel pain, swelling of joints and morning stiffness, contractures, pain, and anterior uveitis leading to blindness. As children who have juvenile arthritis reach adulthood, they face possible continuing disease activity, medication-associated morbidity, and life-long disability and risk for emotional and social dysfunction. In this article we will review the burden of juvenile arthritis for the patient and society and focus on the following areas: patient disability; visual outcome; other medical complications; physical activity; impact on HRQOL; emotional impact; pain and coping; ambulatory visits, hospitalizations and mortality; economic impact; burden on caregivers; transition issues; educational occupational outcomes, and sexuality. The extent of impact on the various aspects of the patients', families' and society's functioning is clear from the existing literature. Juvenile arthritis imposes a significant burden on different spheres of the patients', caregivers' and family's life. In addition, it imposes a societal burden of significant health care costs and utilization. Juvenile arthritis affects health-related quality of life, physical function and visual outcome of children and impacts functioning in school and home. Effective, well-designed and appropriately tailored interventions are required to improve transitioning to adult care, encourage future vocation/occupation, enhance school function and minimize burden on costs.

    Full Text Available OBJECTIVES: Hydroxychloroquine is an antimalarial agent that has been used in systemic lupus erythematosus and rheumatoid arthritis treatment for many years. Recently, novel mechanisms of action have been proposed, thereby broadening the therapeutic perspective of this medication. The purpose of this study was to evaluate the immunomodulatory activity of hydroxychloroquine in T helper 17 (Th17 cytokines in healthy individuals and patients. METHODS: Eighteen female patients with systemic lupus erythematosus (mean age 39.0±12.9 years and 13 female patients with rheumatoid arthritis (mean age 51.5±7.7 years were recruited from Universidade Federal de Pernambuco-Brazil. The patients were included after fulfilling four classification criteria for systemic lupus erythematosus or rheumatoid arthritis from the American College of Rheumatology. After being stimulated with phorbol 12-myristate 13-acetate and ionomycin in the absence or presence of different concentrations of hydroxychloroquine, the interleukin 6, 17 and 22 levels were quantified with an enzyme-linked immunosorbent assay in culture supernatants of peripheral blood mononuclear cells from healthy individuals and patients. RESULTS: We demonstrated that in peripheral blood mononuclear cells from healthy volunteers and in systemic lupus erythematosus and rheumatoid arthritis patients, there was a significant reduction in the IL-6, IL-17 and IL-22 supernatant levels after adding hydroxychloroquine. CONCLUSIONS Our in vitro results demonstrated that hydroxychloroquine inhibits IL-6, IL-17 and IL-22 production and contributes to a better understanding of the mechanism of action of this medication.

    Full Text Available OBJECTIVE: To provide a table indicating the risk for developing anti citrullinated protein antibody (ACPA positive rheumatoid arthritis (RA according to one's HLA-DRB1 genotype. METHODS: We HLA-DRB1 genotyped 857 patients with ACPA positive RA and 2178 controls from South Eastern and Eastern France and calculated Odds Ratios (OR for developing RA for 106 of 132 possible genotypes accounting for 97% of subjects. RESULTS: HLA-DRB1 genotypic ORs for developing ACPA positive RA range from 28 to 0.19. HLA-DRB1 genotypes with HLA-DRB1*04SE (HLA-DRB1*0404, HLA-DRB1*0405, HLA-DRB1*0408, HLA-DRB1*04∶01, HLA-DRB1*01 are usually associated with high risk for developing RA. The second HLA-DRB1 allele in genotype somewhat modulates shared epitope associated risk. We did not identify any absolutely protective allele. Neither the Reviron, nor the du Montcel models accurately explains our data which are compatible with the shared epitope hypothesis and suggest a dosage effect among shared epitope positive HLA-DRB1 alleles, double dose genotypes carrying higher ORs than single dose genotypes. CONCLUSION: HLA-DRB1 genotypic risk for developing ACPA positive RA is influenced by both HLA-DRB1 alleles in genotype. We provide an HLA-DRB1 genotypic risk table for ACPA positive RA.

    Increasing evidence indicates an increased risk of tuberculosis (TB) for rheumatoid arthritis (RA) patients receiving biologic therapy, and the effectiveness of isoniazid prophylaxis (INHP) in TB prevention. We aimed to examine 1) the incidence rate (IR) and risk factors for TB among RA patients receiving different therapies; 2) INHP effectiveness for TB prevention; 3) mortality rates after TB diagnosis in patients receiving different therapies. This retrospective study was conducted using a nationwide database: 168,720 non-RA subjects and a total of 42,180 RA patients including 36,162 csDMARDs-exposed, 3,577 etanercept-exposed, 1,678 adalimumab-exposed and 763 rituximab-exposed patients. TB risk was 2.7-fold higher in RA cohort compared with non-RA group, with an adjusted hazard ratio (aHR) of 2.58. Advanced age, male, the use of corticosteroids≧5mg/day, and the presence of diabetes mellitus (DM), chronic obstructive pulmonary disease and chronic kidney disease were risk factors for developing TB. Using csDMARDs-exposed group as reference, aHR of TB was the highest with adalimumab treatment (1.52), followed by etanercept (1.16), and the lowest with rituximab (0.08). INHP could effectively reduce TB risk in biologics-exposed patients. Mortality rates after TB diagnosis were higher in RA patients, particularly the elderly and those with DM, with lower rates in adalimumab-exposed patients compared with csDMARDs-exposed patients. In conclusion, TB risk was increased in patients receiving TNF-α inhibitors, but the risk associated with rituximab therapy was relatively low. With the effectiveness of INHP shown in the prevention of biologics-associated TB, stricter implementation of INHP should be beneficial. The mortality from biologics–associated TB may be efficiently reduced through increased awareness. PMID:27064275

    Recent experimental studies suggest that risk aversion is negatively related to cognitive ability. In this paper we report evidence that this relation might be spurious. We recruit a large subject pool drawn from the general Danish population for our experiment. By presenting subjects with choice...... tasks that vary the bias induced by random choices, we are able to generate both negative and positive correlations between risk aversion and cognitive ability. Structural estimation allowing for heterogeneity of noise yields no significant relation between risk aversion and cognitive ability.

    Despite the progress in human leukocyte antigen (HLA) causal variant mapping, independent localization of major histocompatibility complex (MHC) risk from classical HLA genes is challenging. Here, we conducted a large-scale MHC fine-mapping analysis of rheumatoid arthritis (RA) in a Japanese population (6,244 RA cases and 23,731 controls) population by using HLA imputation, followed by a multi-ethnic validation study including east Asian and European populations (n = 7,097 and 23,149, respectively). Our study identified an independent risk of a synonymous mutation at HLA-DOA, a non-classical HLA gene, on anti-citrullinated protein autoantibody (ACPA)-positive RA risk (p = 1.4 × 10(-9)), which demonstrated a cis-expression quantitative trait loci (cis-eQTL) effect on HLA-DOA expression. Trans-ethnic comparison revealed different linkage disequilibrium (LD) patterns in HLA-DOA and HLA-DRB1, explaining the observed HLA-DOA variant risk heterogeneity among ethnicities, which was most evident in the Japanese population. Although previous HLA fine-mapping studies have identified amino acid polymorphisms of the classical HLA genes as driving genetic susceptibility to disease, our study additionally identifies the dosage contribution of a non-classical HLA gene to disease etiology. Our study contributes to the understanding of HLA immunology in human diseases and suggests the value of incorporating additional ancestry in MHC fine-mapping. PMID:27486778

    As the treatment of rheumatoid arthritis (RA) moves towards earlier and more consistently maintained therapy, often with highly toxic medications, the importance of assessing patients' health-related quality of life (HR-QOL) is of increasing concern to healthcare providers, insurers and policy-makers. As the course of RA can extend 20 years or more, and as patient involvement in their care and evaluation increases, the goal of therapy should be to work towards the HR-QOL desired by the patien...

    2016-09-01

    Dactylitis is a common feature of psoriatic arthritis (PsA); local physical trauma has been identified as a possible contributing factor. The aim of this study was to explore differences in forefoot plantar pressures in patients with PsA with and without dactylitis and compare to healthy controls. Thirty-six participants were recruited into three groups: group A PsA plus a history of dactylitis; group B PsA, no dactylitis; group C control participants. Forefoot plantar pressures were measured barefoot and in-shoe at the left second and fourth toes and corresponding metatarsophalangeal joints. Temporal and spatial parameters were measured and data from the foot impact scale for rheumatoid arthritis (FIS-RA), EQ5D and health assessment questionnaire (HAQ) were collected. Pressure time integral peak plantar pressure, and contact time barefoot and in-shoe were not significantly different between groups. Temporal and spatial parameters reported no significant differences between groups. ANOVA analysis and subsequent post hoc testing using Games-Howell test yielded significance in FIS-RA scores between both PsA groups versus controls, A p ≤ 0.0001 and PsA group B p history of dactylitis does not appear to worsen patient reported outcomes.

    Full Text Available Reviewing the relationships between polyunsaturated FAs (PUFAs with inflammation and rheumatoid arthritis disorders, the PUFAs containing ω-3, ω-6 and ω-9, these ω-3FAs levels were correlated with ω-6: ω-3 ratios including arachidonic acid (AA, eicosapentaenoic acid (EPA and docosahexaenoic acid (DHA. Based on previously-reports, the levels of ω-3 FAs considered being as a 'lower risk' category for inflammation and rheumatoid arthritis. Certain PUFAs ratios may aid in inflammation and rheumatoid arthritis-related risk assessment. PUFA are the most effective for the production of oil with high concentration of DHA and EPA content significantly.

    Full Text Available Reactive arthritis is an acute, sterile, non-suppurative and inflammatory arthropaty which has occured as a result of an infectious processes, mostly after gastrointestinal and genitourinary tract infections. Reiter syndrome is a frequent type of reactive arthritis. Both reactive arthritis and Reiter syndrome belong to the group of seronegative spondyloarthropathies, associated with HLA-B27 positivity and characterized by ongoing inflammation after an infectious episode. The classical triad of Reiter syndrome is defined as arthritis, conjuctivitis and urethritis and is seen only in one third of patients with Reiter syndrome. Recently, seronegative asymmetric arthritis and typical extraarticular involvement are thought to be adequate for the diagnosis. However, there is no established criteria for the diagnosis of reactive arthritis and the number of randomized and controlled studies about the therapy is not enough.

  8. Psoriatic arthritis

    International Nuclear Information System (INIS)

    In the past 10 years, a number of well-controlled surveys of psoriatic patients selective for the presence of arthritis have been conducted. A Canadian group reported that of 100 patients admitted to the hospital for treatment of psoriasis, 32 had clinical or radiologic evidence of psoriatic arthritis, and 17 had both types of evidence. Eighty patients with radiologic evidence of spinal or sacroiliac involvement were asymptomatic, and seven had clinical evidence of peripheral arthritis but without radiologic evidence. The authors concluded that psoriatic arthritis is a common event in patients with severe psoriasis and that it is associated with more extensive skin disease than is found in patients without arthritis. The information gathered from these epidemiologic studies coupled with clinical, radiologic, and serologic characteristics have provided the basis for the current belief that psoriatic arthritis is indeed a distinct entity

    OBJECTIVES: Gene expression signatures can provide an unbiased view into the molecular changes underlying biologically and medically interesting phenotypes. We therefore initiated this study to identify signatures that would be of utility in studying rheumatoid arthritis (RA). METHODS: We used...... microarray profiling of peripheral blood mononuclear cells (PBMCs) in 30 RA patients to assess the effect of different biologic agent (biologics) treatments and to quantify the degree of a type-I interferon (IFN) signature in these patients. A numeric score was derived for the quantification step and applied...... showing RA to be heterogeneous for an IFN component. A comparison of individuals currently untreated with a biologic with those treated with infliximab, tocilizumab, or abatacept suggested that each biologic induces a specific gene signature in PBMCs.

    Full Text Available Objective. To determine frequency and significance of traditional risk factors of cardiovascular pathology development and to assess features of carotids atherosclerotic damage in women of reproductive age with rheumatoid arthritis (RA. Material and methods. 85 women with RA (mean age 42,1±6,8 years and 32 healthy women (mean age 43,2±6,7 years were included. Traditional risk factors of cardiovascular diseases (CVD were examined. Blood lipid spectrum was assessed by content of total cholesterol (CTC, triglycerides (TG and high density lipoprotein cholesterol (HDLC. Low density lipoprotein cholesterol (LDLC and atherogenity index (AI were calculated. To reveal subclinical forms of atherosclerosis common carotid arteries (CCA duplex scanning with measurement of intima-media complex (IMC was performed using ultrasound system “Acuson 128/XP10” (USA by linear sensor with 7 MHz frequency. C- reactive protein (CRP was assessed by immuno-enzyme assay. Results. Hypertension and lipid metabolism disturbance were the most prevalent risk factors of development and progression of CVD in women of reproductive age with RA. Subclinical atherosclerosis characterized by thickening of IMC was more frequent in RA pts than in healthy women (p<0,001. Presence of extra-articular RA manifestations was accompanied by significant IMC thickening in the region of carotid artery bulb and internal carotid artery (p<0,001, p=0,003. Carotid artery IMC was significantly increased at 3rd RA activity degree in comparison with 1st activity degree (p=0,016 and in the presence of rheumatoid factor in serum (p=0,026. RA pts had IMC thickening irrespectively from CVD history. Conclusion. RA activity as well as HDLC, LDLC and CRP concentration are predictors of vascular atherosclerotic damage in RA

    2010-06-01

    Full Text Available Inflammation of the vascular wall with endothelial dysfunction and subsequent activation of inflammatory immune response play pivotal roles in the early development of the atherosclerotic process not only in adults with rheumatoid arthritis (RA, but also in children with juvenile idiopathic arthritis (JIA. This hypothesis was supported by our findings from autopsy examination, revealing atherosclerosis lesions in about 30�0children with JIA. The established methods of assessing pre-clinical atherosclerosis include measurement of biochemical markers of endothelium impairment and ultrasonographic examination of vessels (FMD, IMT. The authors suggest that revealing structural and functional impairment of peripheral microvessels by means of static and dynamic videocapillaroscopy can give clinicians a chance to identify even younger patients with JIA/RA at high risk of atherosclerosis.

    2014-01-01

    Full Text Available Background. The incidence of breast cancer in RA patients remains controversial. Thus we performed a meta-analysis to investigate the impact of RA on breast cancer. Methods. Published literature was available from PubMed, Embase, and Cochrane Library. Pooled standardized incidence rate (SIR was computed by random-effect model analysis. Results. We identified 16 separate studies in the present study, in which the number of patients ranged from 458 to 84,475. We did not find the increased cancer risk in RA patients (SIR=0.86, 95% CI=0.72–1.02. However, subgroup analysis showed that breast cancer risk in RA patients was positively different in Caucasians (SIR=0.82, 95% CI=0.73–0.93 and non-Caucasians (SIR=1.21, 95% CI=1.19–1.23, respectively. In subgroup analysis by style, a reduced incidence was found in hospital-based case subjects (SIR=0.82, 95% CI=0.69–0.97. Similarly, subgroup analysis for adjusted factors indicated that in A3 (age and sex and A4 (age, sex, and race/ethnicity the risk was decreased (SIR=0.87, 95% CI=0.76–0.99; SIR=0.63, 95% CI=0.59–0.67. Conclusions. The meta-analysis revealed no increased breast cancer risk in RA patients. However, in the subgroup analysis, the risk of breast cancer is increased in non-Caucasians patients with RA while it decreased in Caucasian population, hospital-based case subjects, and A3 group. Such relationship may provide preference for risk of breast cancer in different population.

    Full Text Available Total hip replacement (THR is successful in treating hip arthritis. Prosthetic survivorship may depend on the medications taken by the patient; particularly, the role of benzodiazepines and related drugs (Z-drugs with THR revision has been poorly investigated. Our objective was to compare THR short-term survivorship according to level of exposure to benzodiazepine and Z-drugs.All French patients aged 40 years or older, having undergone primary THR from January 1, 2009, through December 31, 2012, for arthritis according to French national health insurance databases were included in the cohort. Outcome of interest was THR revision, including any surgical procedure in which the implant or any component was changed or removed. Follow-up started the day the primary THR was performed. Observations were right-censored on December 31, 2014, if neither revision nor death had yet occurred. Exposure of interest was the cumulative defined daily doses per day (cDDD/day of benzodiazepines and Z-drugs dispensed within 6 months before or after inclusion. We defined four exposure groups; cDDD/d = 0: unexposed; 0.38: high exposure. THR survivorship was assessed according to level of exposure to benzodiazepines and Z-drugs in univariate and multivariate Cox models adjusted for patient, THR and implanting center characteristics.The study cohort comprised 246,940 individuals: mean age at baseline, 69.9 years; women, 57.9%; unexposed: 51.7%; low exposure: 16.7%; medium exposure: 15.9%; and high exposure: 15.7%. During the median 45-month follow-up, 9043 individuals underwent prosthetic revision. Adjusted hazard ratios in low, medium and high exposed groups were 1.18 (95%CI, 1.12-1.26; P<0.001, 1.32 (95%CI, 1.24-1.40; P<0.001 and 1.37 (95%CI, 1.29-1.45; P<0.001, respectively, compared to unexposed.Exposure to benzodiazepines and Z-drugs is associated with an increased risk of THR revision, with a dose-response relationship.

This narrative Review provides an overview of mental health comorbidities in RA, and discusses how these comorbidities interact with disease processes, including dysregulation of inflammatory responses, prolonged difficulties with pain and fatigue, and the development of cognitive and behavioural responses that could exacerbate the physical and psychological difficulties associated with RA. This article describes how the social context of individuals with RA affects both their coping strategies and their psychological responses to the disease, and can also impair responses to treatment through disruption of patient-physician relationships and treatment adherence. Evidence from the literature on chronic pain suggests that the resulting alterations in neural pathways of reward processing could yield new insights into the connections between disease processes in RA and psychological distress. Finally, the role of psychological interventions in the effective and comprehensive treatment of RA is discussed. PMID:27411910

    Full Text Available Aim. To detect the frequency of subclinical atherosclerosis in rheumatoid arthritis patients without clinically evident atherosclerosis and to correlate its presence with the disease activity. Patients and Methods. Our study includes 112 RA patients (group 1 and 40 healthy controls (group 11. All patients and controls were subjected to full history taking, clinical examination, and laboratory investigations. Carotid intima media wall thickness (IMT and carotid plaques were measured in both groups by B-mode ultrasonography; also color duplex Doppler ultrasound of the brachial artery was done to detect endothelial function. Results. There is atherosclerosis in 31.3% of asymptomatic RA patients compared with only 5% in controls P=0.003**. A significant difference was detected in patients with and without atherosclerosis regarding duration of the disease P=0.0001*** and patient’s age P=0.01*. There is highly statistical significant correlation between atherosclerosis and disease activity index. Conclusion. The frequency of subclinical atherosclerosis was high in long-term active RA patients.

  4. Reactive arthritis.

    Reactive arthritis is one of the spondyloarthropathy family of clinical syndromes. The clinical features are those shared by other members of the spondyloarthritis family, though it is distinguished by a clear relationship with a precipitating infection. Susceptibility to reactive arthritis is closely linked with the class 1 HLA allele B27; it is likely that all sub-types pre-dispose to this condition. The link between HLA B27 and infection is mirrored by the development of arthritis in HLA B27-transgenic rats. In this model, arthritis does not develop in animals maintained in a germ-free environment. Infections of the gastrointestinal, genitourinary and respiratory tract appear to provoke reactive arthritis and a wide range of pathogens has now been implicated. Although mechanistic parallels may exist, reactive arthritis is distinguished from Lyme disease, rheumatic fever and Whipple's disease by virtue of the distinct clinical features and the link with HLA B27. As in these conditions both antigens and DNA of several micro-organisms have been detected in joint material from patients with reactive arthritis. The role of such disseminated microbial elements in the provocation or maintenance of arthritis remains unclear. HLA B27-restricted T-cell responses to microbial antigens have been demonstrated and these may be important in disease pathogenesis. The importance of dissemination of bacteria from sites of mucosal infection and their deposition in joints has yet to be fully understood. The role of antibiotic therapy in the treatment of reactive arthritis is being explored; in some circumstances, both the anti-inflammatory and anti-microbial effects of certain antibiotics appear to be valuable. The term reactive arthritis should be seen as a transitory one, reflecting a concept which may itself be on the verge of replacement, as our understanding of the condition develops. Nevertheless it appropriately describes arthritis that is associated with demonstrable

  5. [Juvenile idiopathic arthritis: Definition and classification].

    2016-04-01

    Juvenile idiopathic arthritis (JIA) is a group of diseases defined by the presence of arthritis of more than 6weeks duration in patients aged less than 16years and with unknown etiology. The international classification based on clinical and biological criteria define each type of JIA: systemic, oligoarticular, polyarticular with and without rheumatoid factor, enthesitis-related arthritis, and psoriatic arthritis. However, some discussions persist concerning systemic-onset juvenile idiopathic arthritis, whose clinical symptoms and pathogenic mechanisms are quite similar to those observed in autoinflammatory diseases, arthritis with antinuclear factors (poly- and oligoarticular) that could be considered as a homogenous group, and a family history of psoriasis that frequently led to unclassified arthritis. Better knowledge of the pathogenic mechanisms should improve the initial clinical classification with more homogeneous groups of patients and reduce the number of unclassified cases of arthritis.

  12. Risk considerations related to lung modeling

    International Nuclear Information System (INIS)

    Improved lung models provide a more accurate assessment of dose from inhalation exposures and, therefore, more accurate dose-response relationships for risk evaluation and exposure limitation. Epidemiological data for externally irradiated persons indicate that the numbers of excess respiratory tract carcinomas differ in the upper airways, bronchi, and distal lung. Neither their histogenesis and anatomical location nor their progenitor cells are known with sufficient accuracy for accurate assessment of the microdosimetry. The nuclei of sensitive cells generally can be assumed to be distributed at random in the epithelium, beneath the mucus and tips of the beating cilia and cells. In stratified epithelia, basal cells may be considered the only cells at risk. Upper-airway tumors have been observed in both therapeutically irradiated patients and in Hiroshima-Nagasaki survivors. The current International Commission on Radiological Protection Lung-Model Task Group proposes that the upper airways and lung have a similar relative risk coefficient for cancer induction. The partition of the risk weighting factor, therefore, will be proportional to the spontaneous death rate from tumors, and 80% of the weighting factor for the respiratory tract should be attributed to the lung. For Weibel lung-model branching generations 0 to 16 and 17 to 23, the Task Group proposes an 80/20 partition of the risk, i.e., 64% and 16%, respectively, of the total risk. Regarding risk in animals, recent data in rats indicate a significantly lower effectiveness for lung-cancer induction at low doses from insoluble long-lived alpha-emitters than from Rn daughters. These findings are due, in part, to the fact that different regions of the lung are irradiated. Tumors in the lymph nodes are rare in people and animals exposed to radiation.44 references

  13. Abuse and HIV-related risk.

    Science.gov (United States)

    Benson, J D

    1995-04-01

    Research has been conducted on the effects of childhood abuse that may lead to HIV risk-taking behaviors in adolescence and adulthood. There is evidence of a higher incidence of childhood abuse among HIV-infected individuals and those at highest risk, but not enough evidence to confirm childhood abuse as a root cause of risk-taking. Research is beginning to show important connections between psychological trauma and risk, and to suggest therapeutic approaches. The trauma of childhood sexual abuse is retained by the victims, which can cause dissociative defenses and damaging feelings of self-efficacy which may affect safer sex practices. To identify sexual abuse as an issue in therapy, it is advised that counselors develop client histories regarding relationships, sexual expression and identity, substance use, suicidality, and other recurring self-destructive patterns of thought and behavior. The treatment goal is to assist the patient in understanding how abuse has affected feelings, thoughts, and relationship styles, and to recognize patterns that lead directly to HIV-related risk or that set the stage for risky activities. The critical aspect of treatment is to accurately assess the patient's coping skills when determining the course of treatment. ¿¿¿¿¿¿¿ PMID:11362459

  14. Risk factors for age-related maculopathy.

    LENUS (Irish Health Repository)

    Connell, Paul P

    2012-02-01

    Age-related maculopathy (ARM) is the leading cause of blindness in the elderly. Although beneficial therapeutic strategies have recently begun to emerge, much remains unclear regarding the etiopathogenesis of this disorder. Epidemiologic studies have enhanced our understanding of ARM, but the data, often conflicting, has led to difficulties with drawing firm conclusions with respect to risk for this condition. As a consequence, we saw a need to assimilate the published findings with respect to risk factors for ARM, through a review of the literature appraising results from published cross-sectional studies, prospective cohort studies, case series, and case control studies investigating risk for this condition. Our review shows that, to date, and across a spectrum of epidemiologic study designs, only age, cigarette smoking, and family history of ARM have been consistently demonstrated to represent risk for this condition. In addition, genetic studies have recently implicated many genes in the pathogenesis of age-related maculopathy, including Complement Factor H, PLEKHA 1, and LOC387715\\/HTRA1, demonstrating that environmental and genetic factors are important for the development of ARM suggesting that gene-environment interaction plays an important role in the pathogenesis of this condition.

  15. Viral arthritis.

    Marks, Michael; Marks, Jonathan L

    2016-04-01

    Acute-onset arthritis is a common clinical problem facing both the general clinician and the rheumatologist. A viral aetiology is though to be responsible for approximately 1% of all cases of acute arthritis with a wide range of causal agents recognised. The epidemiology of acute viral arthritis continues to evolve, with some aetiologies, such as rubella, becoming less common due to vaccination, while some vector-borne viruses have become more widespread. A travel history therefore forms an important part of the assessment of patients presenting with an acute arthritis. Worldwide, parvovirus B19, hepatitis B and C, HIV and the alphaviruses are among the most important causes of virally mediated arthritis. Targeted serological testing may be of value in establishing a diagnosis, and clinicians must also be aware that low-titre autoantibodies, such as rheumatoid factor and antinuclear antibody, can occur in the context of acute viral arthritis. A careful consideration of epidemiological, clinical and serological features is therefore required to guide clinicians in making diagnostic and treatment decisions. While most virally mediated arthritides are self-limiting some warrant the initiation of specific antiviral therapy. PMID:27037381

    Cross-reactivity or molecular mimicry may be one of the underlying mechanisms involved in the etiopathogenesis of rheumatoid arthritis (RA). Antiserum against the RA susceptibility sequence EQKRAA was shown to bind to a similar peptide ESRRAL present in the hemolysin of the gram-negative bacterium Proteus mirabilis, and an anti-ESRRAL serum reacted with EQKRAA. There was no reactivity with either anti-EQKRAA or anti-ESRRAL to a peptide containing the EDERAA sequence which is present in HLA-DRB1*0402, an allele not associated with RA. Furthermore, the EQKRAA and ESRRAL antisera bound to a mouse fibroblast transfectant cell line (Dap.3) expressing HLA-DRB1*0401 but not to DRB1*0402. However, peptide sequences structurally related to the RA susceptibility motif LEIEKDFTTYGEE (P. mirabilis urease), VEIRAEGNRFTY (collagen type II) and DELSPETSPYVKE (collagen type XI) did not bind significantly to cell lines expressing HLA-DRB1*0401 or HLA-DRB1*0402 compared to the control peptide YASGASGASGAS. It is suggested here that molecular mimicry between HLA alleles associated with RA and P. mirabilis may be relevant in the etiopathogenesis of the disease. PMID:10338479

    Full Text Available OBJECTIVE: Rheumatoid arthritis (RA is a chronic inflammatory disease associated with increased cardiovascular (CV mortality. Since CD40-CD154 binding has direct consequences on inflammation process initiation, we aimed to replicate previous findings related to disease susceptibility in Spanish RA population. Furthermore, as the major complication in RA disease patients is the development of CV events due to accelerated atherosclerosis, and elevated levels of CD40L/CD154 are present in patients with acute myocardial infarction, we assessed the potential association of CD40 and CD154/CD40L gene variants with CV risk in Spanish RA patients. METHODS: One thousand five hundred and seventy-five patients fulfilling the 1987 ACR classification criteria for RA and 1600 matched controls were genotyped for the CD40 rs1883832, rs4810485 and rs1535045 and CD154 rs3092952 and rs3092920 gene polymorphisms, using predesigned TaqMan single nucleotide polymorphism genotyping assays. Afterwards, we investigated the influence of CD40-CD154 gene variants in the development of CV events. Also, in a subgroup of 273 patients without history of CV events, we assessed the influence of these polymorphisms in the risk of subclinical atherosclerosis determined by carotid ultrasonography. RESULTS: Nominally significant differences in the allele frequencies for the rs1883832 CD40 gene polymorphism between RA patients and controls were found (p=0.038. Although we did not observe a significant association of CD40-CD154 gene variants with the development of CV events, an ANCOVA model adjusted for sex, age at the time of the ultrasonography assessment, follow-up time, traditional CV risk factors and anti-cyclic citrullinated peptide antibodies disclosed a significant association (p=0.0047 between CD40 rs1535045 polymorphism and carotid intima media thickness, a surrogate marker of atherosclerosis.

  2. Radionuclide dispersion and related radiological risk

    International Nuclear Information System (INIS)

    Since 1945 some 130 accidents with radioactive sources have been reported. In the early phase of such an accident it is important to detect, identify and locate the radionuclide dispersion and to assess the related radiological risk.Transport models and mobile systems for surveillance of the environment would be used for this purpose. Accidents with dangerous radioactive sources can lead to serious health effects for individuals of the population. In many cases of a widespread dispersion (with a length scale of a few kilometres around the point of release) of the activity of such sources, the risk to the population would be small. The release of radioactive material in an urban environment could cause great concern in the population. (author)

  3. Caucasian and Asian specific rheumatoid arthritis risk loci reveal limited replication and apparent allelic heterogeneity in north Indians.

    Directory of Open Access Journals (Sweden)

    Pushplata Prasad

    Full Text Available Genome-wide association studies and meta-analysis indicate that several genes/loci are consistently associated with rheumatoid arthritis (RA in European and Asian populations. To evaluate the transferability status of these findings to an ethnically diverse north Indian population, we performed a replication analysis. We investigated the association of 47 single-nucleotide polymorphisms (SNPs at 43 of these genes/loci with RA in a north Indian cohort comprising 983 RA cases and 1007 age and gender matched controls. Genotyping was done using Infinium human 660w-quad. Association analysis by chi-square test implemented in plink was carried out in two steps. Firstly, association of the index or surrogate SNP (r2>0.8, calculated from reference GIH Hap-Map population was tested. In the second step, evidence for allelic/locus heterogeneity at aforementioned genes/loci was assessed for by testing additional flanking SNPs in linkage equilibrium with index/surrogate marker.Of the 44 European specific index SNPs, neither index nor surrogate SNPs were present for nine SNPs in the genotyping array. Of the remaining 35, associations were replicated at seven genes namely PTPN22 (rs1217407, p = 3×10(-3; IL2-21 (rs13119723, p = 0.008; HLA-DRB1 (rs660895, p = 2.56×10(-5; rs6457617, p = 1.6×10(-09; rs13192471, p = 6.7×10(-16; TNFA1P3 (rs9321637, p = 0.03; CCL21 (rs13293020, p = 0.01; IL2RA (rs2104286, p = 1.9×10(-4 and ZEB1 (rs2793108, p = 0.006. Of the three Asian specific loci tested, rs2977227 in PADI4 showed modest association (p<0.02.

    Dysfunctional transverse and alar craniovertebral ligaments can cause instability and osseous destruction in rheumatoid arthritis (RA). This study examined (1) the feasibility of high-resolution magnetic resonance imaging (MRI) of these ligaments in RA and (2) the relation between ligament high-signal changes and atlantoaxial subluxation and RA duration/severity. Consecutive RA patients (n=46) underwent clinical examination, functional radiography, and high-resolution MRI. Two blinded radiologists rated MRI image quality, graded ligament high-signal changes 0-3 on proton-weighted sequences using an existing grading system, and assessed cervical spine rheumatic changes on short tau inversion recovery images. Agreement was analyzed using kappa and relations using multiple logistic regression. MRI images had good quality in 42 (91.3%) of 46 patients and were interpretable in 44 (32 women and 12 men, median age/disease duration 60.4/9.1 years). MRI grades 2-3 changes of the transverse and alar ligaments showed moderate and good interobserver agreement (kappa 0.59 and 0.78), respectively, and prevalence 31.8% and 34.1%. Such ligament changes were more frequent with increasing anterior atlantoaxial subluxation (p=0.012 transverse, p=0.028 alar), higher erythrocyte sedimentation rate (p=0.003 transverse), positive rheumatoid factor (p=0.002 alar), and neck pain (p = 0.004 alar). This first study of high-resolution MRI of these ligaments in RA showed high feasibility and relations with atlantoaxial subluxation, RA disease activity, and neck pain. The clinical usefulness of such MRI needs further evaluation. (orig.)

  7. Phenotypic alterations of neuropeptide Y and calcitonin gene-related peptide-containing neurons innervating the rat temporomandibular joint during carrageenan-induced arthritis

    Directory of Open Access Journals (Sweden)

    2012-10-01

    Full Text Available The aim of this study was to identify immunoreactive neuropeptide Y (NPY and calcitonin gene-related peptide (CGRP neurons in the autonomic and sensory ganglia, specifically neurons that innervate the rat temporomandibular joint (TMJ. A possible variation between the percentages of these neurons in acute and chronic phases of carrageenan-induced arthritis was examined. Retrograde neuronal tracing was combined with indirect immunofluorescence to identify NPY-immunoreactive (NPY-IR and CGRP- immunoreactive (CGRP-IR neurons that send nerve fibers to the normal and arthritic temporomandibular joint. In normal joints, NPY-IR neurons constitute 78±3%, 77±6% and 10±4% of double-labeled nucleated neuronal profile originated from the superior cervical, stellate and otic ganglia, respectively. These percentages in the autonomic ganglia were significantly decreased in acute (58±2% to superior cervical ganglion and 58±8% to stellate ganglion and chronic (60±2% to superior cervical ganglion and 59±15% to stellate ganglion phases of arthritis, while in the otic ganglion these percentages were significantly increased to 19±5% and 13±3%, respectively. In the trigeminal ganglion, CGRP-IR neurons innervating the joint significantly increased from 31±3% in normal animals to 54±2% and 49±3% in the acute and chronic phases of arthritis, respectively. It can be concluded that NPY neurons that send nerve fibers to the rat temporomandibular joint are located mainly in the superior cervical, stellate and otic ganglia. Acute and chronic phases of carrageenan-induced arthritis lead to an increase in the percentage of NPY-IR parasympathetic and CGRP-IR sensory neurons and decrease in the percentage of NPY-IR sympathetic neurons related to TMJ innervation.

    Full Text Available Rheumatoid arthritis (RA generally starts at the age when many women have already become mothers; however, it may occur in childhood or adolescence. Furthermore, there has been recently a women’s tendency to plan pregnacy for a more mature age, which necessitates a discussion about gestation in this disease. Investigation of mechanisms pregnancy can influence the development of RA both in the gestation and long-term periods is of important theoretical and practical value. The results of these investigations may be used to develop new treatments for RA and management tactics for patients during pregnancy and lactation. The  aper gives the data available in the literature on fertility in RA, impact of pregnancy on its activity and that of RA on the course and outcomes of gestation, as well as current ideas on lactation and use of oral contraceptives in RA. Particular attention is given to drug therapy in pregnant and breastfeeding women with RA: groups of anti-rheumatic drugs are considered in detail in relation to the safety of or a potential risk from their use. A therapeutic algorithm and recommendations for pregnancy planning and a follow-up of patients with RA during gestation are proposed.

    Objectives: To evaluate the utility of sequentially acquired, post hoc fused, magnetic resonance imaging (MRI) and multi-pinhole single photon emission computed tomography (MPH-SPECT) with technetium-99m-labeled disphosphonates (Tc99m-DPD) for the identification of finger joints with later erosive progression in early rheumatoid arthritis (ERA) patients. Methods: Ten consecutive ERA patients prospectively underwent MPH-SPECT and MRI of metacarpophalangeal (MCP) joints prior to and after 6 months methotrexate therapy. Tc99m-DPD uptake was measured at proximal and distal MCP sites using regional analysis. The course of joint pathologies was scored according to the Rheumatoid Arthritis MRI Score (RAMRIS) criteria. Results: The frequency of increased Tc99m-DPD uptake, synovitis and bone marrow edemadecreased under MTX therapy; but the number of bone erosions increased. Joints with progressive and new erosions on follow-up had a higher baseline Tc99m-DPD uptake (2.64 ± 1.23 vs. 1.43 ± 0.91) (p = 0.02). Conclusions: Joints with erosive progression are characterized by an early increased Tc99m-DPD uptake, even in absence of MRI bone pathologies. Tc99m-DPD MPH-SPECT might thus be of additional value to morphological MRI for the identification of RA patients with a high risk for erosive progression.

    Full Text Available Not so long ago, information technology (IT risk occupied a small corner of operational risk - the opportunity loss from a missed IT development deadline. Today, the success of an entire financial institution may lay on managing a broad landscape of IT risks. IT risk is a potential damage to an organization's value, resulting from inadequate managing of processes and technologies. IT risk includes the failure to respond to security and privacy requirements, as well as many other issues such as: human error, internal fraud through software manipulation, external fraud by intruders, obsolesce in applications and machines, reliability issues or mismanagement. The World Economic Forum provides best information about this problem. They rank a breakdown of critical information infrastructure among the most likely core global risks, with 10-20 % likelihood over the next 10 years and potential worldwide impact of $250 billion. Sustained investment in IT - almost $1.2 trillion or 29% of 2006 private-sector capital investment in the U.S. alone fuels growing exposure to IT risk. Greg Hughes, chief strategy officer in Symantec Corp. recently claimed "IT risk management is more than using technology to solve security problems. With proper planning and broad support, it can give an organization the confidence to innovate, using IT to outdistance competitors".

    Full Text Available BACKGROUND & OBJECTIVES: Patients with Rheumatoid Arthritis (R.A. have a marked increase in Carotid Atherosclerosis independent of traditional risk factors like family history of myocardial infarction in first degree male relatives younger than 55 years of age or first degree female relatives younger than 65 years of age, smoking, hypertension (D efined as blood pressure of 140/90 mm hg or higher, diabetes mellitus and fasting serum cholesterol levels including age. Chronic inflammation and possibly disease severity and duration are atherogenic in Rheumatoid Arthritis patients. Preclinical disease may also be identified by using ultrasonography to determine carotid intimal - media thickness, an indirect measure of atherosclerosis. The common carotid artery Intima media thickness in Rheumatoid Arthritis patients is positively associated with disease duration, Early Rheumatoid Arthritis (D uration less or = 1 year is associated with lesser Intima media thickness than was Rheumatoid Arthritis of longer duration. Increased carotid artery Intima media thickness and the presence of carotid plaque are associated with markers of systemic inflammation in patients with Rheumatoid Arthritis and in healthy subjects. OBJECTIVE OF THE STUDY: To determine preclinical atherosclerosis occurring prematurely in patients of Rheumatoid Arthritis by ultrasonograhic measurement Common Carotid Artery Intima media thickness and to evaluate the risk factors associated with arterial intima media thickness in patient of Rheumatoid Arthritis. RESULTS: In RA patients, common carotid artery IMT was significantly higher when compared to healthy controls (0.65 ± 0.06 v/s 0.57 ± 0.049 and was significantly associated with the duration of RA, swollen joint count and erosive changes on hand x - ray independently of other confounding variables.

    Full Text Available Objective. Programmed cell death 1 (PD-1 induces negative signals to T cells during interaction with its ligands and is therefore a candidate gene in the development of autoimmune diseases such as rheumatoid arthritis (RA. Herein, we investigate the association of PDCD-1 polymorphisms with the risk of RA among Chinese patients and healthy controls. Methods. Using the PCR-direct sequencing analysis, 4 PDCD-1 SNPs (rs36084323, rs11568821, rs2227982, and rs2227981 were genotyped in 320 RA patients and 309 matched healthy controls. Expression of PD-1 was determined in peripheral blood lymphocytes by flow cytometry and quantitative real-time reverse transcriptase polymerase chain reaction. Results. We observed that the GG genotype of rs36084323 was associated with a increased risk for developing RA (OR 1.70, 95% 1.11–2.61, P=0.049. Patients carrying G/G genotype displayed an increased mRNA level of PD-1 (P=0.04 compared with A/A genotype and healthy controls. Meanwhile, patients homozygous for rs36084323 had induced basal PD-1 expression on activated CD4+ T cells. Conclusion. The PDCD-1 polymorphism rs36084323 was significantly associated with RA risk in Han Chinese population. This SNP, which effectively influenced the expression of PD-1, may be a biomarker of early diagnosis of RA and a suitable indicator of utilizing PD-1 inhibitor for treatment of RA.

    Increasing evidence indicates that the risk of nontuberculous mycobacteria (NTM) disease is elevated in patients with rheumatoid arthritis (RA). However, the risk factors and outcomes for NTM disease among RA patients remain unclear. We conducted a case-control study and estimated odds ratios (ORs) for RA patients with NTM disease according to comorbidities and anti-rheumatic medications by using conditional logistic regression. Prior tuberculosis history (adjusted OR (aOR) =5.58, p 51, Ptrend = 0.007) were associated with a significantly increased risk of NTM disease in RA patients. The predominant species causing NTM disease in RA patients was Mycobacterium intracellulare (46.0%). Most NTM isolates were resistant to the majority of the antibiotics that are currently available, which maybe caused treatment failure; hospitalization and mortality are increased. To prevent and treat NTM disease efficiently, we suggested that it is important to monitor the development of NTM disease in RA patients receiving therapy with corticosteroids, particularly in those with predisposing factors.

  10. Anti-inflammatory role of methotrexate in adjuvant arthritis: effect on substance p and calcitonin gene-related peptide in thymus and spleen

    International Nuclear Information System (INIS)

    To investigate the anti-inflammatory effect of methotrexate (MTX) in rats with adjuvant arthritis through its influence on the expression of proinflammatory neuropeptides, substance P (SP) and calcitonin gene-related peptide (CGRP) in immune organs, thymus and spleen. Adjuvant arthritis was induced in rats by inoculation with heat-killed mycobacteria. One group of arthritic rats (n=6) was treated with MTX (0.2 mg/kg body weight, subcutaneously) on every 4th day for a period of 18 weeks, while another group of arthritic rats (n=6) was treated with physiological saline served as control. At the end of experiment, animals were sacrificed and thymus and spleen were dissected and prepared for immunohistochemical analysis. The neuronal density of SP and CGRP immunoreactivity in thymus and spleen was assessed by semi-quantitative analysis. There was a marked reduction in hind paw swelling and inflammation in the MTX-treated rats after 18 weeks of treatment. Restoration of joint spaces (tibiotalar and subtalar) was seen after 9 weeks of MTX treatment. CGRP-positive nerve fibres were significantly reduced (p=0.0001) in thymus of rats treated with MTX compared to control rats. SP-positive nerve fibers were also found to be decreased in thymus of rats treated with MTX compared to controls, however, the decrease was not statistically significant. The neuronal density of SP and CGRP-immunoreactivity in spleen was not significantly different in MTX-treated and placebo-treated rats. In arthritic rats, MTX significantly reduced CGRP expression in thymus. Suppression of pro-inflammatory neuropeptides, such as CGRP and probably SP could be another mechanism by which MTX produces its antiinflammatory effect in adjuvant arthritis. (author)

  11. Relative and absolute risk in epidemiology and health physics

    International Nuclear Information System (INIS)

    The health risk from ionizing radiation commonly is expressed in two forms: (1) the relative risk, which is the percentage increase in natural disease rate and (2) the absolute or attributable risk which represents the difference between the natural rate and the rate associated with the agent in question. Relative risk estimates for ionizing radiation generally are higher than those expressed as the absolute risk. This raises the question of which risk estimator is the most appropriate under different conditions. The absolute risk has generally been used for radiation risk assessment, although mathematical combinations such as the arithmetic or geometric mean of both the absolute and relative risks, have also been used. Combinations of the two risk estimators are not valid because the absolute and relative risk are not independent variables. Both human epidemiologic studies and animal experimental data can be found to illustrate the functional relationship between the natural cancer risk and the risk associated with radiation. This implies that the radiation risk estimate derived from one population may not be appropriate for predictions in another population, unless it is adjusted for the difference in the natural disease incidence between the two populations

    Rheumatoid arthritis is a chronic autoimmune-based inflammatory disease that leads to progressive joint degeneration, disability, and an increased risk of cardiovascular complications, which is the main cause of mortality in this population of patients. Although several biomarkers are routinely used in the management of rheumatoid arthritis, there is a high demand for novel biomarkers to further improve the early diagnosis of rheumatoid arthritis, stratification of patients, and the prediction of a better response to a specific therapy. In this study, the metabolomics approach was used to provide relevant biomarkers to improve diagnostic accuracy, define prognosis and predict and monitor treatment efficacy. The results indicated that twelve metabolites were important for the discrimination of healthy control and rheumatoid arthritis. Notably, valine, isoleucine, lactate, alanine, creatinine, GPC  APC and histidine relative levels were lower in rheumatoid arthritis, whereas 3-hydroxyisobutyrate, acetate, NAC, acetoacetate and acetone relative levels were higher. Simultaneously, the analysis of the concentration of metabolites in rheumatoid arthritis and 3 months after induction treatment revealed that L1, 3-hydroxyisobutyrate, lysine, L5, acetoacetate, creatine, GPC+APC, histidine and phenylalanine were elevated in RA, whereas leucine, acetate, betaine and formate were lower. Additionally, metabolomics tools were employed to discriminate between patients with different IL-17A genotypes. Metabolomics may provide relevant biomarkers to improve diagnostic accuracy, define prognosis and predict and monitor treatment efficacy in rheumatoid arthritis. PMID:26476882

    To test the hypothesis that MR imaging guided triamcinolone acetonide injection into the sacroiliac joints of children with enthesitis-related arthritis is feasible, accurate and safe; and effectively reduces sacroiliac inflammation and disease progression. A retrospective analysis of 14 children (6/14 [43%] female, 8/14 (57%) male; mean age, 13.2 years; range, 6-16 years) who received MR imaging guided sacroiliac joint injections at 0.2 Tesla or 1.5 Tesla for enthesitis-related arthritis and acute sacroilitis refractory to medical therapy was performed. 20 mg triamcinolone acetonide were injected. Assessed were intra-articular drug delivery; image quality, duration, and complications. Success of therapy was defined by change of sacroiliac inflammation. Remission time and erosions were assessed by follow-up MRI (range, 10-22 months). Twenty four procedures resulted in intra-articular injection. Image quality was sufficient. No complications occurred. Procedure time was 40 min. Sedation time was 22 min. Success of therapy was achieved in 11/14 (79%) children. Sacroiliac inflammation decreased significantly (-59%). Median remission time was 13.7 months. No erosions occurred. MR imaging guided steroid injection of the sacroiliac joints is feasible, accurate, and safe and can effectively reduce sacroiliac inflammatory activity and may therefore aid in the prevention of disease progression.

    In September 2006, the Nuclear Safety Commission of Japan revised the Regulatory Guide for Reviewing Seismic Design of Nuclear Power Reactor Facilities, which has introduced, in addition to the conventional deterministic approach, the concept of probabilistic 'residual risk' that arises from the earthquake exceeding the defined design standard earthquake Ss. In response to this, the Nuclear and Industrial Safety Agency (NISA) requested the utilities to evaluate the residual risk for all the domestic nuclear power plants, in addition to the deterministic back-check to the revised guideline. In this residual risk evaluation, conformity will be checked for each plant to satisfy the performance objectives (i.e. core damage frequency and containment failure frequency) and the safety goal (i.e. average individual risk). In this situation, it is inevitable for JNES to establish consecutive evaluation system for seismic PSA models, including level-1 (core damage frequency), level-2 (containment failure frequency and release of radioactive materials) and level-3 (radiological consequence), in order to perform its own seismic PSA, keeping adequate quality level. With the established evaluation system, it becomes possible to timely and efficiently review the results of the utilities through cross-checking utilizing the results of JNES. In 2010, level-1, 2, 3 PSA modeling for all the domestic light water reactors have been almost completed as well as PSA modeling for multi-unit site and tsunami was progressed to prepare for the review for the 'residual risk' by the utilities.

    Objective Glutathione S-transferase (GST) and heme oxygenase-1 (HMOX1) genes encode enzymes that detoxify carcinogens and protect against oxidative stress. We studied gene-smoking interactions on rheumatoid arthritis (RA) susceptibility. Methods 549 matched Caucasian RA cases and controls were selected from the Nurses' Health Study. Genotyping by TaqMan and BioTrove identified GSTM1, GSTT1 homozygous deletions (null) and GSTP1 (rs1695), HMOX1 (rs2071746) alleles, respectively. We studied gene-smoking interactions on the risk of all RA and serologic RA phenotypes in separate logistic models adjusted for covariates. We assessed multiplicative interactions with product terms in the logistic models and additive interactions with the attributable proportion due to interaction (AP). For replication, we repeated significant analyses in an independent case-control sample from the Epidemiologic Investigation of RA. Results For all RA risk, we observed: multiplicative (p=0.05) and additive (AP=0.53, p=0.0005) interactions between GSTT1-null and smoking and multiplicative interaction (p=0.05) between HMOX1 and smoking. For seropositive RA risk, we found multiplicative (p=0.01) and additive (AP=0.63, p<0.0001) interactions between GSTT1-null and smoking and additive interaction (AP=0.41, p=0.03) between HMOX1 and smoking. After correction for multiple comparisons, additive interactions for GSTT1-null and smoking remained significant. GSTM1-null and GSTP1 did not show significant interactions. No associations were seen with seronegative RA. In replication analyses, we observed significant multiplicative (p=0.04) and additive (AP=0.32, p=0.02) interactions between GSTT1-null and smoking for ACPA-positive RA risk. Conclusion We observed significant gene-environment interactions between GSTT1-null and heavy smoking on RA risk. Future studies are needed to assess the impact of these interactions on RA prediction. PMID:20597111

  18. Relative Hazard and Risk Measure Calculation Methodology Rev 1

    International Nuclear Information System (INIS)

    Documentation of the methodology used to calculate relative hazard and risk measure results for the DOE complex wide risk profiles. This methodology is used on major site risk profiles. In February 1997, the Center for Risk Excellence (CRE) was created and charged as a technical, field-based partner to the Office of Science and Risk Policy (EM-52). One of the initial charges to the CRE is to assist the sites in the development of ''site risk profiles.'' These profiles are to be relatively short summaries (periodically updated) that present a broad perspective on the major risk related challenges that face the respective site. The risk profiles are intended to serve as a high-level communication tool for interested internal and external parties to enhance the understanding of these risk-related challenges. The risk profiles for each site have been designed to qualitatively present the following information: (1) a brief overview of the site, (2) a brief discussion on the historical mission of the site, (3) a quote from the site manager indicating the site's commitment to risk management, (4) a listing of the site's top risk-related challenges, (5) a brief discussion and detailed table presenting the site's current risk picture, (6) a brief discussion and detailed table presenting the site's future risk reduction picture, and (7) graphic illustrations of the projected management of the relative hazards at the site. The graphic illustrations were included to provide the reader of the risk profiles with a high-level mental picture to associate with all the qualitative information presented in the risk profile. Inclusion of these graphic illustrations presented the CRE with the challenge of how to fold this high-level qualitative risk information into a system to produce a numeric result that would depict the relative change in hazard, associated with each major risk management action, so it could be presented graphically. This report presents the methodology developed

    BACKGROUND:Patients with rheumatoid arthritis have high cardiovascular disease risks and postsurgical complications such as postoperative infection and wound healing problems in the process of total joint arthroplasty. OBJECTIVE:To retrospectively review the peri-operative risks when undergoing total joint replacement in patients with rheumatoid arthritis, and assess these risks, propose solutions to guide clinical practice for better peri-operative management. METHODS:The studies related with perioperative cardiovascular risk, the risk of infection of total joint replacement were retrieved by the first author from PubMed database, GOOGLE academic database, CNKI database, Wanfang database, VIP database from 2000 to 2015 through computer. The key words in English and Chinese were respectively“Rheumatoid arthritis, Total joint arthroplast, Perioperative management, Infection, Postsurgical complications, Corticosteroid, Disease modifying antirheumatic drugs, Biologics”. Old and repetitive studies were excluded. RESULTS AND CONCLUSION:A total of 97 articles were retrieved. Total y 53 articles which content was inconsistent with the research themes were excluded, and 44 papers were included in the analysis. We should make a comprehensive cardiovascular examination for the patients with rheumatoid arthritis before operation. If the cardiovascular disease of the patient is unstable, this condition should be clarified and treated appropriately before surgery, otherwise, patients need to check heart function, and predict the operation risk;We should reasonably arrange the anti-rheumatism medicines and corticosteroid during perioperative, so as to make a balance between reducing postoperative infection and preventing the condition relapse;Because rheumatoid arthritis often easy to erode the cervical spine, we should conduct routine imaging examination for the patients before total joint replacement. Movement should be gentle when general anesthesia was needed.%背景

    Recent experimental studies suggest that risk aversion is negatively related to cognitive ability. In this paper we report evidence that this relation might be spurious. We recruit a large subject pool drawn from the general Danish population for our experiment. By presenting subjects with choice...... tasks that vary the bias induced by random choices, we are able to generate both negative and positive correlations between risk aversion and cognitive ability. Structural estimation allowing for heterogeneity of noise yields no significant relation between risk aversion and cognitive ability.

    Curtis, Stanley B.

    1993-01-01

    A number of considerations must go into the process of determining the risk of deleterious effects of space radiation to travelers. Among them are (1) determination of the components of the radiation environment (particle species, fluxes and energy spectra) which will encounter, (2) determination of the effects of shielding provided by the spacecraft and the bodies of the travelers which modify the incident particle spectra and mix of particles, and (3) determination of relevant biological effects of the radiation in the organs of interest. The latter can then lead to an estimation of risk from a given space scenario. Clearly, the process spans many scientific disciplines from solar and cosmic ray physics to radiation transport theeory to the multistage problem of the induction by radiation of initial lesions in living material and their evolution via physical, chemical, and biological processes at the molecular, cellular, and tissue levels to produce the end point of importance.

  6. Carbohydrate metabolism disorders in patients with rheumatoid arthritis and ankylosing spondylitis – impact of treatment

    Directory of Open Access Journals (Sweden)

    Piotr Dąbrowski

    2014-06-01

    Full Text Available Chronic inflammation – the crucial pathogenic mechanism of rheumatoid arthritis and ankylosing spondylitis – is the main cause of accelerated atherosclerosis, insulin resistance and well-known consequences related to it. The conservative treatment of rheumatoid arthritis and ankylosing spondylitis may provide a significant influence on glucose metabolism. The paper is a literature overview concerning insulin resistance and impaired glucose metabolism during treatment with disease-modifying drugs including biologic DMARDs (disease-modifying antirheumatic drugs, corticosteroids and commonly used non-steroidal anti-inflammatory drugs (NSAID. It has been found that the risk of carbohydrate disorders among those patients is much lower after therapy with hydroxychloroquine, methotrexate and TNF blockers – particularly with infliximab. The NSAID may play an important protective role in reducing risk of diabetes. The recent data show, contrary to general opinion, the advantageous outcome for glucose metabolism after treatment with corticosteroids, especially in the early active stage of rheumatoid arthritis.

  12. Relative safeguards risks of advanced reactor concepts

    International Nuclear Information System (INIS)

    The purpose of this report is to develop a procedure to quantitatively assess the risk to diversion of the nuclear material in the fuel cycle for seven advanced reactor design concepts (LWR-Pu, LMFBR, HTGR, GCFR, MSBR, LWBR, HWR). Each stage in each of the seven reactor fuel cycles is evaluated and the result of the evaluation is a comparison among the various fuel cycles. This method of evaluation is used to determine the stages in a nuclear reactor fuel cycle that are most susceptible to diversion; it also gives an indication of what factors contribute to that susceptibility

  14. Lung manifestation in rheumatoid arthritis: High-resolution CT in mutual relation to skeletal changes and laboratory parameters

    International Nuclear Information System (INIS)

    Purpose: It has been the aim of the following study to evaluate pulmonary changes in rheumatoid arthritis with high-resolution CT and to assess their correlation with joint manifestation and laboratory paramters. Material and methods: The authors prospectively performed computed tomography (CT) in 83 patients with rheumatoid arthritis and graded pulmonary changes for frequency and severity. Included were patients with 6-7/7 ARA, BSR>25/1 min and mean disease duration of 12 years (range, 1-44). Data of medical and drug histories, smoking habits, blood levels of rheumatoid factor (RF), antinuclear antibodies (ANA) and C-reactive protein as well as the degree of joint involvement were taken into account. Results: 58 patients (70%) had pathological CT scans showing the following abnormalities: Interlobular thickening (44.5%), intralobular thickening (34%), nonseptal linear attenuation (35%), nodular or linear pleural thickening (32.5%), ground-glass pattern (19%), centrilobular nodules (13%), honeycombing (13%) and bronchiolectasis (9%). Intralobular thickening, honeycombing and pleural thickening were associated with a higher degree of joint manifestation; pleural thickening, honeycombing and ground-glass pattern were associated with a higher level of rheumatoid factor. There was no relationship between pulmonary changes and either the duration of the disease, antinuclear antibodies (ANA) or C-reactive protein. Conclusion: CT may be a useful noninvasive tool for recognition of RA-associated lung disease. Interstitial lung changes are frequent and they are independent of the duration of the disease. Pulmonary interstitial changes are more frequent and more severe in RF-positive patients and in case of more severe joint involvement. (orig.)

  15. Several regions in the major histocompatibility complex confer risk for anti-CCP-antibody positive rheumatoid arthritis, independent of the DRB1 locus.

    2008-01-01

    Recent evidence suggests that additional risk loci for RA are present in the major histocompatibility complex (MHC), independent of the class II HLA-DRB1 locus. We have now tested a total of 1,769 SNPs across 7.5Mb of the MHC located from 6p22.2 (26.03 Mb) to 6p21.32 (33.59 Mb) derived from the Illumina 550K Beadchip (Illumina, San Diego, CA, USA). For an initial analysis in the whole dataset (869 RA CCP + cases, 1,193 controls), the strongest association signal was observed in markers near the HLA-DRB1 locus, with additional evidence for association extending out into the Class I HLA region. To avoid confounding that may arise due to linkage disequilibrium with DRB1 alleles, we analyzed a subset of the data by matching cases and controls by DRB1 genotype (both alleles matched 1:1), yielding a set of 372 cases with 372 controls. This analysis revealed the presence of at least two regions of association with RA in the Class I region, independent of DRB1 genotype. SNP alleles found on the conserved A1-B8-DR3 (8.1) haplotype show the strongest evidence of positive association (P ~ 0.00005) clustered in the region around the HLA-C locus. In addition, we identified risk alleles that are not present on the 8.1 haplotype, with maximal association signals (P ~ 0.001-0.0027) located near the ZNF311 locus. This latter association is enriched in DRB1*0404 individuals. Finally, several additional association signals were found in the extreme centromeric portion of the MHC, in regions containing the DOB1, TAP2, DPB1, and COL11A2 genes. These data emphasize that further analysis of the MHC is likely to reveal genetic risk factors for rheumatoid arthritis that are independent of the DRB1 shared epitope alleles. PMID:18309376

    2013-10-01

    Given the widespread use of empirical actuarial risk tools in corrections and forensic mental health, it is important that evaluators and decision makers understand how scores relate to recidivism risk. In the current study, we found strong evidence for a relative risk interpretation of Static-99R scores using 8 samples from Canada, United Kingdom, and Western Europe (N = 4,037 sex offenders). Each increase in Static-99R score was associated with a stable and consistent increase in relative risk (as measured by an odds ratio or hazard ratio of approximately 1.4). Hazard ratios from Cox regression were used to calculate risk ratios that can be reported for Static-99R. We recommend that evaluators consider risk ratios as a useful, nonarbitrary metric for quantifying and communicating risk information. To avoid misinterpretation, however, risk ratios should be presented with recidivism base rates. PMID:23264543

  18. Superior forniceal advancement conjunctival pedicle (SFACP) in the management of corneal perforations and impending perforations due to rheumatoid arthritis related autoimmune corneal melts

    International Nuclear Information System (INIS)

    Peripheral ulcerative keratitis (PUK) is a disorder consisting of a crescent-shaped destructive inflammation of the perilimbal corneal stroma. PUK may occur in variety of systemic diseases including collagen vascular disease. We describe the outcome of superior forniceal advancement conjunctival pedicle (SFACP) in two patients with corneal perforation and impending perforation due to rheumatoid arthritis (RA) related auto immune corneal melt that has not previously been reported. Both patients had good recovery with restoration of vision when SFACP was performed as an adjunct to systemic immunosuppressive agents. SFACP is a valuable surgical option which may have an important role in reducing progression of corneal melt and underlying disease when used along with adequate systemic immunosuppressive agents.

    2016-07-01

    Rheumatoid arthritis (RA) is a systemic chronic inflammatory disease characterized by extensive synovitis resulting in erosions of articular cartilage and marginal bone with joint destruction. The lack of immunological tolerance in RA represents the first step toward the development of autoimmunity. Susceptible individuals, under the influence of environmental factors, such as tobacco smoke, and silica exposure, develop autoimmune phenomena that result in the presence of autoantibodies. HLA and non-HLA haplotypes play a major role in determining the development of specific autoantibodies differentiating anti-citrullinated antibodies (ACPA)-positive and negative RA patients. Rheumatoid factor (RF) and ACPA are the serological markers for RA, and during the preclinical immunological phase, autoantibody titers increase with a progressive spread of ACPA antigens repertoire. The presence of ACPA represents an independent risk factor for developing RA in patients with undifferentiated arthritis or arthralgia. Moreover, anti-CarP antibodies have been identified in patients with RA as well as in individuals before the onset of clinical symptoms of RA. Several autoantibodies mainly targeting post-translational modified proteins have been investigated as possible biomarkers to improve the early diagnosis, prognosis and response to therapy in RA patients. Psoriatic arthritis (PsA) is distinguished from RA by infrequent positivity for RF and ACPA, together with other distinctive clinical features. Actually, specific autoantibodies have not been described. Recently, anti-CarP antibodies have been reported in sera from PsA patients with active disease. Further investigations on autoantibodies showing high specificity and sensibility as well as relevant correlation with disease severity, progression, and response to therapy are awaited in inflammatory arthritides.

    1977-01-01

    Living in a technological society with large energy requirements involves a number of related actities with attendant health risks, both to the working and to the general public. Therefore, the formulation of some general principles for risk acceptance is necessary. In addition to maximizing benefits and minimizing risk, relevant considerations must be made about the perception of risk as voluntary or involuntary, the number of persons collectively at risk at any one occasion, and the extent to which a risk is a familiar one. With regard to a given benefit, such as a given amount of energy, comparisons of the risks of alternate modes of production may be utilized. However, cost-benefit consideration is essential to the amelioration of current or prospective risks. This is unusual, since it is based on some estimate of the monetary value per premature death averted. It is proposed that increased longevity would be a more satisfactory measure. On a societal basis, large expenditures for additional energy-related pollution control do not appear justifiable since much larger, nonenergy-related health risks are relatively underaddressed. Knowledgeable health professionals could benefit the public by imparting authoritative information in this area.

We recruit a large subject pool drawn from the general Danish population for our experiment. By presenting subjects with choice...... tasks that vary the bias induced by random choices, we are able to generate both negative and positive correlations between risk aversion and cognitive ability. Our results suggest that cognitive ability is related to random decision making rather than to risk preferences....

    2009-01-01

    The literature has so far focused on the risk-return tradeoff in equity markets and ignored alternative risky assets. This paper is the first to examine the presence and significance of an intertemporal relation between expected return and risk in the foreign exchange market. The paper provides new evidence on the intertemporal capital asset pricing model by using high-frequency intraday data on currency and by presenting significant time-variation in the risk aversion parameter.

  13. SMAD3 rs17228212 gene polymorphism is associated with reduced risk to cerebrovascular accidents and subclinical atherosclerosis in anti-CCP negative Spanish rheumatoid arthritis patients.

    Directory of Open Access Journals (Sweden)

    Mercedes García-Bermúdez

    Full Text Available Rheumatoid arthritis (RA is a complex polygenic inflammatory disease associated with accelerated atherosclerosis and increased risk of cardiovascular (CV disease. Previous genome-wide association studies have described SMAD3 rs17228212 polymorphism as an important signal associated with CV events. The aim of the present study was to evaluate for the first time the relationship between this gene polymorphism and the susceptibility to CV manifestations and its potential association with the presence of subclinical atherosclerosis assessed by the evaluation of carotid intima-media thickness (cIMT in patients with RA.One thousand eight hundred and ninety-seven patients fulfilling classification criteria for RA were genotyped for SMAD3 rs17228212 gene polymorphism through TaqMan genotyping assay. Also, subclinical atherosclerosis determined by the assessment of cIMT was analyzed in a subgroup of these patients by carotid ultrasonography.No statistically significant differences were observed when allele frequencies of RA patients with or without CV events were compared. Nevertheless, when RA patients were stratified according to anti-cyclic citrullinated peptide (anti-CCP status, we found that in RA patients who were negative for anti-CCP antibodies, the presence of C allele of SMAD3 rs17228212 polymorphism conferred a protective effect against the risk of cerebrovascular accident (CVA after adjustment for demographic and classic CV risk factors (HR [95%CI]=0.36 [0.14-0.94], p=0.038 in a Cox regression model. Additionally, correlation between the presence of C allele of SMAD3 rs17228212 polymorphism and lower values of cIMT was found after adjustment for demographic and classic CV risk factors (p-value=0.0094 in the anti-CCP negative RA patients.Our results revealed that SMAD3 rs17228212 gene variant is associated with lower risk of CVA and less severe subclinical atherosclerosis in RA patients negative for anti-CCP antibodies. These findings may have

  14. Psoriatic arthritis

    International Nuclear Information System (INIS)

    Psoriatic arthritis (PsA) is a chronic inflammatory joint disease which develops in patients with psoriasis. It is characteristic that the rheumatoid factor in serum is absent. Etiology of the disease is still unclear but a number of genetic associations have been identified. Inheritance of the disease is multilevel and the role of environmental factors is emphasized. Immunology of PsA is also complex. Inflammation is caused by immunological reactions leading to release of kinins. Destructive changes in bones usually appear after a few months from the onset of clinical symptoms. Typically PsA involves joints of the axial skeleton with an asymmetrical pattern. The spectrum of symptoms include inflammatory changes in attachments of articular capsules, tendons, and ligaments to bone surface. The disease can have divers clinical course but usually manifests as oligoarthritis. Imaging plays an important role in the diagnosis of PsA. Classical radiography has been used for this purpose for over a hundred years. It allows to identify late stages of the disease, when bone tissue is affected. In the last 20 years many new imaging modalities, such as ultrasonography (US), computed tomography (CT) and magnetic resonance (MR), have been developed and became important diagnostic tools for evaluation of rheumatoid diseases. They enable the assessment and monitoring of early inflammatory changes. As a result, patients have earlier access to modern treatment and thus formation of destructive changes in joints can be markedly delayed or even avoided

  15. Radiographic manifestations of arthritis in AIDS patients

    International Nuclear Information System (INIS)

    The purpose of this study is to familiarize the radiologist with a newly discovered association between arthritis and acquired immunodeficiency syndrome (AIDS). The authors retrospectively reviewed the clinical and radiographic findings in 31 patients with human immunodeficiency virus (HIV) infection referred to their rheumatology clinic with musculoskeletal complaints. The patients carried a wide range of clinical diagnosis including Reiter syndrome, psoriatic arthritis, undifferentiated seronegative arthritis, isolated enthesopathies, rheumatoid arthritis and osteonecrosis. Radiographs were available in 24 of the 31 patients, and in 20 they showed radiographic features of arthritis, which included soft-tissue swelling periarticular osteoporosis, synovial effusions, sacroiliitis, periosteal reaction, joint space narrowing, marginal erosions, and osteonecrosis. Although the radiographic abnormalities were frequently mild, they were significant, given the short duration of disease in many of their patients (weeks to months) at the time radiographs were obtained. The range of radiographic findings in their series was varied and paralleled the wide range of clinical diagnoses. No findings were pathognomonic for HIV-associated arthritis. Nevertheless, HIV infection needs to be considered in any patient belonging to a recognized risk group who presents with musculoskeletal disease. This is particularly important since immunosupressive drugs used for the treatment of arthritis can be detrimental to patients with HIV infection

  17. A Comparative Metabolomic Evaluation of Behcet's Disease with Arthritis and Seronegative Arthritis Using Synovial Fluid.

    Directory of Open Access Journals (Sweden)

    Joong Kyong Ahn

    Full Text Available Behcet's disease (BD with arthritis is often confused with seronegative arthritis (SNA because of shared clinical symptoms and the lack of definitive biomarkers for BD. To investigate possible metabolic patterns and potential biomarkers of BD with arthritis, metabolomic profiling of synovial fluid (SF from 6 patients with BD with arthritis and 18 patients with SNA was performed using gas chromatography/time-of-flight mass spectrometry in conjunction with univariate and multivariate statistical analyses. A total of 123 metabolites were identified from samples. Orthogonal partial least square-discriminant analysis showed clear discrimination between BD with arthritis and SNA. A set of 11 metabolites were identified as potential biomarkers for BD using variable importance for projection values and the Wilcoxon-Mann-Whitney test. Compared with SNA, BD with arthritis exhibited relatively high levels of glutamate, valine, citramalate, leucine, methionine sulfoxide, glycerate, phosphate, lysine, isoleucine, urea, and citrulline. There were two markers identified, elevated methionine sulfoxide and citrulline, that were associated with increased oxidative stress, providing a potential link to BD-associated neutrophil hyperactivity. Glutamate, citramalate, and valine were selected and validated as putative biomarkers for BD with arthritis (sensitivity, 100%; specificity, 61.1%. This is the first report to present potential biomarkers from SF for discriminating BD with arthritis from SNA. The metabolomics of SF may be helpful in searching for potential biomarkers and elucidating the clinicopathogenesis of BD with arthritis.

  2. Adequacy of relative and absolute risk models for lifetime risk estimate of radiation-induced cancer

    International Nuclear Information System (INIS)

    This report examines the applicability of the relative (multiplicative) and absolute (additive) models in predicting lifetime risk of radiation-induced cancer. A review of the epidemiologic literature, and a discussion of the mathematical models of carcinogenesis and their relationship to these models of lifetime risk, are included. Based on the available data, the relative risk model for the estimation of lifetime risk is preferred for non-sex-specific epithelial tumours. However, because of lack of knowledge concerning other determinants of radiation risk and of background incidence rates, considerable uncertainty in modelling lifetime risk still exists. Therefore, it is essential that follow-up of exposed cohorts be continued so that population-based estimates of lifetime risk are available

    2016-01-01

    Full Text Available The feature of rheumatoid arthritis (RA is the predominant clinical picture of chronic synovial joint inflammation accompanied by progressive cartilage and bone destruction, the pathogenesis of which is greatly due to autoimmune mechanisms. Some investigations demonstrate that a set of poor climatic and geographical factors may influence the development of immune disorders that are a trigger in the development of RA.Objective: to comparative analyze immunological parameters in RA in dwellers from different regions of Uzbekistan.Subjects and methods. The study enrolled RA patients from three Uzbekistan zones: 1 Tashkent (n = 25, 2 Xorazm Region (n = 25; 3 Namangan Region (n = 28.Results and discussion. Comparative analysis of the immune status indicated that the patients living in Zone 2 exhibited a significantly reduced T cell immune response (p < 0.05, a considerably higher count of B lymphocytes (p < 0.001, and significantly lower levels of CD11b+, CD18+, CD25+, and CD95+ cells (p < 0.05 than did those from the two other zones. Examination of the frequency of the monomorphic determinant of histocompatibility Class I (HLA-I antigens revealed its significant decrease in the patients residing in Zones 1 and 3 (p < 0.05 whereas the RA patients from Zone 2 had a significantly higher frequency of HLA-DR (p < 0.05.Conclusion. The comparative analysis shows that the immunological parameters differ in the patients from the three zones of Uzbekistan, which may suggest that the climatic and geographical factors of the environment may influence the course of the disease.

  4. Smoking and Rheumatoid Arthritis

    Directory of Open Access Journals (Sweden)

    Kathleen Chang

    2014-12-01

    Full Text Available Rheumatoid arthritis (RA is a chronic inflammatory disease caused by both genetic and environmental factors. Smoking has been implicated as one of the most important extrinsic risk factors for its development and severity. Recent developments have shed light on the pathophysiology of RA in smokers, including oxidative stress, inflammation, autoantibody formation and epigenetic changes. The association of smoking and the development of RA have been demonstrated through epidemiologic studies, as well as through in vivo and animal models of RA. With increased use of biological agents in addition to standard disease-modifying antirheumatic drugs (DMARDs, there has been interest in how smoking affects drug response in RA treatment. Recent evidence suggests the response and drug survival in people treated with anti-tumour necrosis factor (anti-TNF therapy is poorer in heavy smokers, and possible immunological mechanisms for this effect are presented in the current paper.

    2012-01-01

    Background Rheumatoid Arthritis (RA) is an autoimmune disease characterized by chronic inflammation of the joints that affects approximately 1% of the population worldwide. The HLA-DRB1 gene locus plays a major role in genetic susceptibility to RA, a condition that has been associated with a high cardiovascular morbidity and mortality in many studies. Methodology/Principal Findings The aim of this work was to investigate which types of HLA class II genes are associated with RA in patients from the Brazilian Amazon and their influence on high cardiovascular risk status in this population. For this purpose, a case-control study was carried out with a total of 350 non-Indian individuals made up of a cohort of 132 consecutive RA sufferers and 218 healthy controls. A χ2 test showed that HLADRB1*04 (p<0.0016; OR = 1.89; 95% CI = 1.29–2.79) and HLADRB1*10 (p = 0.0377; OR = 3.81; 95% CI = 1.16–12.50) are the major HLA genes associated with susceptibility to RA. A logistic regression model also showed that the interaction between HLADRB1*04 (p = 0.027; OR = 6.02; 95% CI = 1.21–29.7), age (p = 0.0001; OR = 1.26; 95% CI = 1.13–1.39) and smoking (p = 0.0001; OR = 23.6; 95% CI = 4.25–32.1) is associated with a probability of a high cardiovascular risk status at an early age. Conclusions/Significance The results of this study show for the first time that HLA class II type is associated with RA in Brazilian Amazon populations and that a specific interaction between the HLA-DRB1*04 gene and smoking is associated with a high cardiovascular risk status, as initially reported in the European population. This study therefore contributes to an understanding of gene-environment interactions in RA patients. PMID:22912672

  7. Gender-specific effects of genetic variants within Th1 and Th17 cell-mediated immune response genes on the risk of developing rheumatoid arthritis.

    Full Text Available The present study was conducted to explore whether single nucleotide polymorphisms (SNPs in Th1 and Th17 cell-mediated immune response genes differentially influence the risk of rheumatoid arthritis (RA in women and men. In phase one, 27 functional/tagging polymorphisms in C-type lectins and MCP-1/CCR2 axis were genotyped in 458 RA patients and 512 controls. Carriers of Dectin-2 rs4264222T allele had an increased risk of RA (OR = 1.47, 95%CI 1.10-1.96 whereas patients harboring the DC-SIGN rs4804803G, MCP-1 rs1024611G, MCP-1 rs13900T and MCP-1 rs4586C alleles had a decreased risk of developing the disease (OR = 0.66, 95%CI 0.49-0.88; OR = 0.66, 95%CI 0.50-0.89; OR = 0.73, 95%CI 0.55-0.97 and OR = 0.68, 95%CI 0.51-0.91. Interestingly, significant gender-specific differences were observed for Dectin-2 rs4264222 and Dectin-2 rs7134303: women carrying the Dectin-2 rs4264222T and Dectin-2 rs7134303G alleles had an increased risk of RA (OR = 1.93, 95%CI 1.34-2.79 and OR = 1.90, 95%CI 1.29-2.80. Also five other SNPs showed significant associations only with one gender: women carrying the MCP-1 rs1024611G, MCP-1 rs13900T and MCP-1 rs4586C alleles had a decreased risk of RA (OR = 0.61, 95%CI 0.43-0.87; OR = 0.67, 95%CI 0.47-0.95 and OR = 0.60, 95%CI 0.42-0.86. In men, carriers of the DC-SIGN rs2287886A allele had an increased risk of RA (OR = 1.70, 95%CI 1.03-2.78, whereas carriers of the DC-SIGN rs4804803G had a decreased risk of developing the disease (OR = 0.53, 95%CI 0.32-0.89. In phase 2, we genotyped these SNPs in 754 RA patients and 519 controls, leading to consistent gender-specific associations for Dectin-2 rs4264222, MCP-1 rs1024611, MCP-1 rs13900 and DC-SIGN rs4804803 polymorphisms in the pooled sample (OR = 1.38, 95%CI 1.08-1.77; OR = 0.74, 95%CI 0.58-0.94; OR = 0.76, 95%CI 0.59-0.97 and OR = 0.56, 95%CI 0.34-0.93.

    Full Text Available Significance of psoriasis (PS research is determined by increasing incidence of this disorder, higher frequency of severe clinical forms, e.g., psoriatic arthritis (PsA. Clinical course and outcomes of psoriasis and psoriatic arthritis depend on degree of immunological disturbances and imbalance of cytokine regulation of intercellular interactions. The leading immune disorders involved in pathogenesis of psoriasis and PsA are those characterized by alterations of Th1-type cytokine profile (TNFα, IL-2, IFNγ, etc.. We have analyzed publications that reveal some features of PS and PsA immunopathogenesis associated with nature of the diseases. The review draws attention to relatively new and scarcely studied data concerning the role of cytokines produced by Th17- and Th22-cells (IL-17, IL-22, IL-23, IL-26, IL-19 subfamily (IL-19, IL-20, IL-24 in development of psoriasis and PsA. Search for the immunological markers predisposing for risk of psoriasis and PsA is an important step in personalized approach to their prediction and planning of preventive measures, in order to prevent progression of this pathology.

  10. Relations between radiation risks and radiation protection measuring techniques

    International Nuclear Information System (INIS)

    Relations between radiation risks and radiation protection measuring techniques are considered as components of the radiation risk. The influence of the exposure risk on type and extent of radiation protection measurements is discussed with regard to different measuring tasks. Based upon measuring results concerning the frequency of certain external and internal occupational exposures in the GDR, it has been shown that only a small fraction of the monitored persons are subjected to a high exposure risk. As a consequence the following recommendations are presented: occupationally exposed persons with small exposure risk should be monitored using only a long-term desimeter (for instance a thermoluminescence desimeter). In the case of internal exposure, the surface and air contamination levels should be controlled so strictly that routine measurements of internal contamination need not be performed

    Genotypic variability based genome-wide association studies (vGWASs) can identify potentially interacting loci without prior knowledge of the interacting factors. We report a two-stage approach to make vGWAS applicable to diseases: firstly using a mixed model approach to partition dichotomous phenotypes into additive risk and non-additive environmental residuals on the liability scale and secondly using the Levene's (Brown-Forsythe) test to assess equality of the residual variances across genotype groups per marker. We found widespread significant (P TYK2 and ANKRD55. Both PTPN22 and TYK2 had evidence of interactions reported elsewhere. We conclude that vGWAS can help discover interacting loci for complex diseases but require large samples to find additional signals. PMID:27109064

    Systemic juvenile idiopathic arthritis (sJIA) is an often severe, potentially life-threatening childhood inflammatory disease, the pathophysiology of which is poorly understood. To determine whether genetic variation within the MHC locus on chromosome 6 influences sJIA susceptibility, we performed an association study of 982 children with sJIA and 8,010 healthy control subjects from nine countries. Using meta-analysis of directly observed and imputed SNP genotypes and imputed classic HLA types, we identified the MHC locus as a bona fide susceptibility locus with effects on sJIA risk that transcended geographically defined strata. The strongest sJIA-associated SNP, rs151043342 [P = 2.8 × 10−17, odds ratio (OR) 2.6 (2.1, 3.3)], was part of a cluster of 482 sJIA-associated SNPs that spanned a 400-kb region and included the class II HLA region. Conditional analysis controlling for the effect of rs151043342 found that rs12722051 independently influenced sJIA risk [P = 1.0 × 10−5, OR 0.7 (0.6, 0.8)]. Meta-analysis of imputed classic HLA-type associations in six study populations of Western European ancestry revealed that HLA-DRB1*11 and its defining amino acid residue, glutamate 58, were strongly associated with sJIA [P = 2.7 × 10−16, OR 2.3 (1.9, 2.8)], as was the HLA-DRB1*11—HLA-DQA1*05—HLA-DQB1*03 haplotype [6.4 × 10−17, OR 2.3 (1.9, 2.9)]. By examining the MHC locus in the largest collection of sJIA patients assembled to date, this study solidifies the relationship between the class II HLA region and sJIA, implicating adaptive immune molecules in the pathogenesis of sJIA.

    Background: Solar ultraviolet radiation exposure has been inversely related to prostate cancer incidence and mortality, possibly mediated through vitamin D status. Pigmentation-related traits influence endogenous vitamin D synthesis and may alter risk of prostate cancer. Methods: We examined prostate cancer in relation to hair and eye colour, and skin phototype in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study cohort. Incident cancer was diagnosed in 1982 out of 20 863 men. Multi...

  4. Abnormal bone remodelling in inflammatory arthritis

    1998-01-01

    Osteopenia is responsible for substantial comorbidity in patients suffering from rheumatoid arthritis and is an important factor in the surgical management of joint disease. In animal models of bone loss stimulated by inflammatory arthritis, increased bone remodelling and altered microstructure of bone have been documented. The subchondral bone plate near the joint surface is narrow and perforated by vascular inflammatory invasion, and in the shaft the thin cortices are weakened by giant resorption defects. Biomechanical tests and a mathematical model of bone strength suggest that cortical defects, much larger than those found in normal osteonal remodelling, are principally responsible for the experimentally observed loss of strength. Similarly, these defects may explain the increased femoral fracture risk in rheumatoid arthritis. The osteoclast, the cell resorbing bone, is demonstrated in increased number and activity in rheumatoid arthritis and in animal models. Bisphosphonates, drugs that inhibit osteoclast function, have been shown experimentally to reduce both focal and generalized osteopenia and to prevent loss of bone strength. Bisphosphonates also protect articular cartilage from damage characteristic of inflammatory arthritis. The mechanism of chondroprotection may be prevention of subchondral bone resorption by the osteoclast and also an altered distribution of bone marrow cells. Thus, bisphosphonates, currently in clinical use for other bone metabolic diseases, appear to have potential as prophylaxis and treatment for osteopenia and joint damage in inflammatory arthritis.

    BACKGROUND AND PURPOSE: Myotonic dystrophies (DM) are autosomal dominantly inherited neuromuscular disorders caused by unstable nucleotide repeat expansions. DM and cancer have been associated, but the pathogenesis behind the association remains unclear. It could relate to derived effects of the DM...... genotype in which case non-DM relatives of DM patients would not be expected to be at increased risk of cancer. To elucidate this, a population-based cohort study investigating risk of cancer in relatives of DM patients was conducted. METHODS: DM was identified using the National Danish Patient Registry...... and results of genetic testing. Information on cancer was obtained from the Danish Cancer Registry. A population-based cohort of 5 757 565 individuals with at least one relative was established using the Danish Family Relations Database based on kinship links in the Danish Civil Registration System...

  6. Plasma Interleukin-37 Is Elevated in Patients with Rheumatoid Arthritis: Its Correlation with Disease Activity and Th1/Th2/Th17-Related Cytokines

    2015-01-01

    Full Text Available Interleukin- (IL- 37 is a novel anti-inflammatory cytokine that suppresses immune response and inflammation. This study was performed to determine whether IL-37 was elevated in patients with rheumatoid arthritis (RA and investigate the correlation between IL-37 level and disease activity and the concentration of Th1/Th2/Th17-related cytokines. Clinical parameters of disease activity, including the 28-joint disease activity score (DAS28 and C-reactive protein (CRP, were collected in 34 RA patients and 34 age- and sex-matched healthy controls. Plasma IL-37 was measured by ELISA. Plasma levels of TNF-α, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12, IL-13, IL-17, G-CSF, GM-CSF, IFN-γ, MCP-1, and MIP-1β were analyzed using the Bio-Plex suspension array system. It was found that IL-37 levels were elevated markedly in RA patients and almost undetectable in healthy controls. In addition, IL-37 levels in patients with active RA were significantly enhanced as compared with those in patients of remission. More importantly, IL-37 showed a significant correlation with disease activity (DAS28 and IL-4, IL-7, IL-10, IL-12, and IL-13 concentrations in RA patients. These findings suggest that IL-37 plays an important role in the pathogenesis of RA and may prove to be a potential biomarker of active RA.

    Objective To study the potential risk factors for severe acute respiratory syndromes (SARS)-related deaths in Beijing. Methods Epidemiological data were collected among the confirmed SARS patients officially reported by Beijing Centers for Disease Control and Prevention (BCDC), and information was also supplemented by a follow-up case survey. Chi-square test and multivariate stepwise logistic regression analysis were performed. Results Old age (over 60 years) was found to be significantly associated with SARS-related deaths in the univariate analysis. Also, history of contacting SARS patients within 2 weeks prior to the onset of illness, health occupation, and inferior hospital ranking as well as longer interval of clinic consulting (longer than 1 day) were the risk factors for SARS-related deaths. Multivariate stepwise logistic regression analysis found four risk factors for SARS-related deaths. Conclusion Old age (over 60 years) is the major risk factor for SARS-related deaths.Moreover, hospital health workers, the designated hospitals for SARS clinical services and the interval of consulting doctors (less than 1 day) are protective factors for surviving from SARS.

  8. Human capital and risk aversion in relational incentive contracts

    International Nuclear Information System (INIS)

    This paper examines a self-enforced relational incentive contract between a risk neutral principal and a risk averse agent where the agent's human capital is essential in ex post realization of values. I analyse the effect of outside options on the optimal bonus level, showing how the presence of ex post outside options may impede desirable degrees of performance pay. The effect of risk aversion and incentive responsiveness is analysed by allowing for linear contracts. I show that the first order effect of these parameters are the same as in verifiable contracts, but second order effects show that the optimal bonus level's sensitivity to risk aversion and incentive responsiveness increases with the discount factor. The analysis has interesting implications on firm boundaries and specificity choices. (author)

  9. Analysis of the interferon gamma (rs2430561, +874T/A functional gene variant in relation to the presence of cardiovascular events in rheumatoid arthritis.

    Directory of Open Access Journals (Sweden)

    Mercedes García-Bermúdez

    Full Text Available OBJECTIVE: Rheumatoid arthritis (RA is a chronic inflammatory disease associated with increased cardiovascular (CV morbidity and mortality. Since interferon-gamma (IFN-γ has a direct effect on inflammation, in this study we assessed the potential association of the IFNG functional gene variant rs2430561 with CV disease in patients with RA. METHODS: One thousand six hundred and thirty-five patients fulfilling the 1987 American College of Rheumatology classification criteria for RA were genotyped for the IFNG (rs2430561, +874T/A gene polymorphism using TaqMan genotyping assay. Patients were stratified according to the presence of CV events or not. Logistic regression models to explain the presence of CV disease according to the IFNG rs2430561 allele distribution were performed. The potential influence of this variant in the development of subclinical atherosclerosis was also analyzed in a subgroup of patients with no history of CV events to determine carotid artery intima-media thickness (IMT (n = 286 and presence of carotid plaques. Levels of the cytokine were determined in a subgroup of patients by ELISA. RESULTS: Adjusted logistic regression model disclosed that presence of the minor allele A was not associated with increased risk of suffering CV events in RA patients. Besides, differences did not achieve statistical significance regarding carotid IMT and presence of carotid plaques in RA patients carrying IFNG rs2430561 variant allele. Levels of IFN-γ were higher in patients who had suffered CV events compared to patients who did not. CONCLUSION: Our results do not support a role of IFNG rs2430561 (+874T/A functional gene variant in the development of CV disease in RA patients.

    Pedersen, Carsten Bøcker; Mortensen, Preben Bo

    2006-01-01

    BACKGROUND: Urban birth or upbringing increase schizophrenia risk. Though unknown, the causes of these urban-rural differences have been hypothesized to include, e.g., infections, diet, toxic exposures, social class, or an artefact due to selective migration. METHODS: We investigated the hypothesis...... that traffic related exposures affect schizophrenia risk and that this potential effect is responsible for the urban-rural differences. The geographical distance from place of residence to nearest major road was used as a proxy variable for traffic related exposures. We used a large population....... RESULTS: The geographical distance from place of residence to nearest major road had a significant effect. The highest risk was found in children living 500-1000 metres from nearest major road (RR=1.30 (95% Confidence Interval: 1.17-1.44). However, when we accounted for the degree of urbanization, the...

  14. Can the weather influence arthritis symptoms?

    Directory of Open Access Journals (Sweden)

    Wai Chin Li

    2014-09-01

    Full Text Available By reviewing twelve previous studies on the relationship between the weather and arthritis symptoms, this article summarized the major findings on this controversial topic. It has been supported by most of the studies that arthritis symptoms are associated with weather conditions. Factors such as barometric pressure and temperature were generally believed to be related to arthritis symptoms. However, controversies arose at minor levels. Whether the weather-symptom relationship depends on the specific type of arthritis, weather variables, demographic and pathological heterogeneity of the patients is still a matter of debate. This article calls for standardization in future research design, and hope the mechanism underlying the weather-symptom association will be found.

    Full Text Available Aims of the study were to investigate health-related quality of life (HRQOL in adult patients with former diagnosis of Juvenile Idiopathic Arthritis (JIA, to compare their HRQOL with the general population and to identify factors related to a poor outcome.In 2012, a cross-sectional survey was performed by mailing a questionnaire to a large cohort of former and current patients of the German Centre for Rheumatology in Children and Adolescents. Only adult patients (≥18 years with a diagnosis compatible with JIA were included (n = 2592; response 66%. The questionnaire included information about HRQOL (EQ5D, disease-related questions and socio-demographics. Prevalence and 95% confidence intervals (CI of problems with mobility, self-care, usual activities, pain and anxiety/depression were standardized to the German general population. Factors associated with low HRQOL in JIA patients were identified using logistic regression models.Sixty-two percent of the study population was female; age range was 18-73 years. In all dimensions, JIA patients reported statistically significantly more problems than the general population with largest differences in the pain dimension (JIA patients 56%; 95%CI 55-58%; general population 28%; 26-29% and the anxiety/depression dimension (28%; 27-29% vs. 4%; 4-5%. Lower HRQOL in JIA patients was associated with female sex, older age, lower level of education, still being under rheumatic treatment and disability.HRQOL in adult JIA patients is considerably lower than in the general population. As this cohort includes historic patients the new therapeutic schemes available today are expected to improve HRQOL in future.

  19. Explanatory risk factors in the relations between schizotypy and indicators of suicide risk.

    2016-04-30

    Schizotypy has been linked to suicide risk, but it is not known whether established suicide-related risk factors mediate this relation. The aim of this study was to assess the mediating effects of depressive symptoms, social anxiety, self-esteem, and intimate disclosure in peer relationships in the relation between interpersonal schizotypy and suicide ideation or lifetime suicide attempts. This aim was tested in 590 young adults using a nonparametric bootstrapping procedure. After inclusion of the mediators, interpersonal schizotypy was no longer directly associated with either suicide ideation or lifetime suicide attempts. Depression and self-esteem mediated the relation between interpersonal schizotypy and suicide ideation. No variables mediated the relation between interpersonal schizotypy and lifetime suicide attempts, and there were no significant direct relations when mediators were included. Schizotypy appears to be a distal risk factor for suicidal behavior; assessing depressive symptoms and self-esteem may provide more proximal information about suicide risk, and may be targets for mitigating suicide risk in individuals with schizotypy.

    Full Text Available Giuseppe Murdaca, Francesca Spanò, Francesco PuppoDepartment of Internal Medicine, Clinical Immunology Unit, University of Genoa, Genoa, ItalyAbstract: Rheumatoid arthritis (RA is a chronic inflammatory disease that is associated with joint damage and progressive disability, an increased risk of morbidity related to comorbid conditions and substantial socioeconomic costs. Tumor necrosis factor-alpha (TNF-α is a proinflammatory cytokine known to have a central role in the initial host response to infection and in the pathogenesis of various immune-mediated diseases, such as RA, ankylosing spondylitis, psoriasis and/or psoriatic arthritis, Crohn’s disease, and systemic lupus erythematosus. Five TNF-α inhibitors are available for the clinical use: infliximab; adalimumab; etanercept; golimumab; and certolizumab pegol. Infliximab is a chimeric human/murine IgG1 monoclonal antibody (mAb; adalimumab, and golimumab are human mAbs; certolizumab pegol is composed of the fragment antigen-binding anti-binding domain of a humanized anti-TNF-α mAb, combined with polyethylene glycol to increase its half-life in the body; etanercept is a fusion protein that acts as a “decoy receptor” for TNF-α. In this paper, we will briefly review the current data on efficacy and safety of adalimumab in patients with RA, its potential beneficial effects upon comorbid conditions, such as endothelial dysfunction and accelerated atherosclerosis in RA, and the immunogenicity.Keywords: adalimumab, efficacy, safety, rheumatoid arthritis, VEGF, immunogenicity, infections

  2. Food for thought - Communicating food-related risks

    Directory of Open Access Journals (Sweden)

    Sturloni Giancarlo

    2003-03-01

    Full Text Available In the last few years, a continuous series of food alerts have caught the attention of the media and the public in Europe. First, eggs and pork contaminated with dioxins; then, “mad cow” disease, while, all along in the background, a battle against genetically modified plants has been in progress. These food alerts have had complex repercussions on the perception of risks associated with food production. Experts have often been divided over these issues, and the uncertainty of scientific data has been indicated on more than one occasion as one of the factors that influence risk perception. However, the most important factor seems to be undoubtedly the way in which the risk has been communicated (or not communicated to the public. Therefore, risk communication analysis offers an excellent opportunity to understand the profound changes that are taking place in relations among the scientific community, mass media and other members of civil society now that they are fully aware that scientific and technological innovation, the real driving force of modern industrial society, is a source of development but also a source of risks which are not always acceptable. Within this different context, a debate open to all interested parties appears to have become a dire necessity for the “risk society”, especially as far as food is concerned because food has extremely important psychological, ethical and cultural values.

  3. Relative energy risk: is solar energy riskier than nuclear

    International Nuclear Information System (INIS)

    The discussion of risk analysis is divided into three parts: (a) a brief discussion of the methodology which can be used, (b) a listing of some of the major assumptions, and (c) the results of a comparison of eleven energy systems. The energy systems considered here can be divided into two groups: conventional, i.e., those in fairly widespread use, like coal or nuclear, and non-conventional, i.e., all others, like solar and wind. In general, although some of these non-conventional systems have been described as risk-free, they are not. In fact, compared to some conventional systems like natural gas and nuclear, technologies like solar and windpower have relatively high risk. The reason is simple. Because of the dilute nature of the energy they handle, solar and wind systems, when compared on the quantity of their energy production, require a considerable amount of apparatus as compared to other systems. In turn, this apparatus requires a large amount of material and construction labor to build and install. Associated with each ton of material and hour of labor is a definite number of accidents, diseases and deaths, according to labor statistics. When the risk is summed up in this way, we find that non-conventional systems generally have high risk. In particular, to answer the question posed in the title of this talk, solar energy seems to have a higher risk than nuclear power, when the methodology outlined below is used

    Full Text Available Background. Peritonitis represents a major complication of peritoneal dialysis (PD. The aim of this paper was to systematically collect data on patient-related risk factors for PD-associated peritonitis, to analyze the methodological quality of these studies, and to summarize published evidence on the particular risk factors. Methods. Studies were identified by searches of Pubmed (1990–2012 and assessed for methodological quality by using a modified form of the STROBE criteria. Results. Thirty-five methodologically acceptable studies were identified. The following nonmodifiable risk factors were considered valid and were associated with an increased risk of peritonitis: ethnicity, female gender, chronic lung disease, coronary artery disease, congestive heart failure, cardiovascular disease, hypertension, antihepatitis C virus antibody positivity, diabetes mellitus, lupus nephritis or glomerulonephritis as underlying renal disease, and no residual renal function. We also identified the following modifiable, valid risk factors for peritonitis: malnutrition, overweight, smoking, immunosuppression, no use of oral active vitamin D, psychosocial factors, low socioeconomic status, PD against patient’s choice, and haemodialysis as former modality. Discussion. Modifiable and nonmodifiable risk factors analyzed in this paper might serve as a basis to improve patient care in peritoneal dialysis.

    2016-01-01

    Chronic stress is a public health problem that affects a significant part of the population. While the physiological damage it causes is under ongoing scrutiny, its behavioral effects have been overlooked. This is one of the first studies to examine the relation between chronic stress and decision-making, using a standard lottery paradigm. We measured risk taking in the gain domain through binary choices between financially incentivized lotteries. We then measured self-reported chronic stress with the Trier Inventory for the Assessment of Chronic Stress (TICS). We additionally collected hair samples in a subsample of volunteers, in order to quantify accumulation of the stress hormone cortisol. We discovered a significant positive, though modest, correlation between self-reported chronic stress and risk taking that is stronger for women than for men. This confirms part of the findings in acute stress research that show a connection between higher stress and increased risk taking. However, unlike the biologically-based results from acute stress research, we did not identify a significant relation between hair cortisol and behavior. In line with previous literature, we found a clear gender difference in risk taking and self-reports: women generally take less risk and report slightly higher stress levels than men. We conclude that perceived chronic stress can impact behavior in risky situations. PMID:26858663

    Full Text Available The aim of the report is to assess the risk factors among patients with spontaneous ipsilateral subconjunctival hemorrhage (SCH who presented to the outpatients’ department in General Hospital of Veria, Veria, Greece. Thirty-five patients with SCH participated in the study. A thorough case history was taken and a full ophthalmic examination was performed to identify the risk factors related to the clinical finding. The common hematological parameters associated with the coagulation profile of each patient were evaluated. With the exception of SCH, the ophthalmic examination was normal in all patients. Identified risk factors include history of systemic hypertension (21 patients [60%], mean systolic value: 170 mmHg±15 mmHg, strenuous exercise [19 patients (54%] and minor ocular trauma [5 patients (14%]. Other risk factors [each in 2 patients (6%] included: diabetes mellitus, smoking, severe cough, straining at stool, and weight lifting. Seven patients (20% were under medication related to bleeding diathesis. The values of the blood coagulation parameters were within the normal limits in all patients. Twenty-nine patients (83% had elevated blood pressure during the ophthalmological examination. Our study provides documentation regarding the potential risk factors associated with SCH. It is interesting to observe the high incidence of hypertension among the patients with SCH. Therefore, it is highly recommended that the blood pressure be checked in all patients with SCH and that the patients be referred to a general practitioner for further management if indicated.

    Full Text Available OBJECTIVES: To investigate the prevalence of dyslipoproteinemia in a homogeneous cohort of polyarticular juvenile idiopathic arthritis patients. METHODS: Based on the National Cholesterol Education Program, fasting lipoprotein levels and risk levels for coronary artery disease were determined in 28 patients with polyarticular juvenile idiopathic arthritis. The exclusion criteria included diabetes, thyroid dysfunction, smoking, proteinuria, lipid-lowering drugs, and hormone/diuretic therapy. Disease activity, disease duration, and therapy with corticosteroids and/or chloroquine were defined at the time of lipid measurements. RESULTS: Dyslipoproteinemia was identified in 20 of the 28 (71% patients with polyarticular juvenile idiopathic arthritis. The primary lipoprotein risk factor was decreased high-density lipoprotein cholesterol (57%, followed by elevated levels of low-density lipoprotein cholesterol (18%, triglycerides (14%, and total cholesterol (7%. The male patients had decreased high-density lipoprotein cholesterol levels than the female patients (p5 years disease duration. CONCLUSIONS: Dyslipoproteinemia is highly prevalent in patients with polyarticular juvenile idiopathic arthritis and is primarily related to decreased high-density lipoprotein cholesterol levels; therefore, early intervention is essential.

    Methotrexate (MTX), the most commonly used anti-rheumatic drug against RA, enters the cell via the action of the reduced folate carrier 1(RFC1). A major polymorphism of the RFC1 gene, 80G/A, has been reported to influence the activity of RFC1, resulting in variable intracellular MTX-polyglutamate (MTX-PG) levels. However, the association studies addressing the RFC1 80G/A polymorphism and MTX efficacy or toxicity in Rheumatoid arthritis (RA) has yielded conflicting results. In the present meta-analysis, we aimed to evaluate the association between the RFC1 80G/A polymorphism and MTX efficacy or toxicity in RA patients. A total 17 studies met our inclusion criteria. Among them, 12 studies with 2049 subjects reported the association between the RFC1 80G/A and MTX response, and 12 studies involving 2627 subjects were on MTX-related toxicity. Meta-analysis revealed significant association between RFC1 80G/A polymorphism and MTX efficacy (odds ratio (OR) for the A allele=1.29, 95% confidence interval (CI) 1.05-1.67, P=0.02; for AA genotype: OR=1.49, 95%CI 1.17-1.907, P=0.001). However, no association could be detected in the analysis of MTX-related toxicity. Stratification by ethnic population also indicated an association between this polymorphism and MTX efficacy in Asian group (P=0.002 for A allele; P=0.003 for AA genotype), but not in the Caucasian group (P=0.15 for A allele; P=0.05 for AA genotype). In both Asian and Caucasian sub-groups, no influence of the RFC1 80G/A polymorphism on MTX toxicity can be detected. In conclusion, the RFC1 G80A polymorphism is associated with responsiveness to MTX therapy, but may not be associated with MTX toxicity in RA patients. PMID:27233001

    Full Text Available The paper considers the problems of comorbidities in patients with rheumatoid arthritis (RA. Two or more RA-related conditions were diagnosed according to the results of the QUEST-RA program implemented in 34 countries. Osteoarthritis along with hypertension, hyperlipidemia, and osteoporosis was detected among the most commonly diseases. Owing to expanded diagnostic capabilities, the recognition and treatment of the comorbidities have recently received much attention, as embodied in the draft Association of Rheumatologists of Russia Guidelines for RA management (2014; Part 1. The concept and major characteristics of secondary osteoarthritis in RA are analyzed. It is precisely the inflammatory process and underlying disease-related risk factors, including treatment, that have impact on the development of secondary osteoarthritis and patients’ quality of life as a whole. All this allows an inference about the mechanisms closely intertwined with the underlying disease for the development of secondary osteoarthritis, which initiates cartilage damage and further remodeling. Primary and secondary osteoarthritis was comparatively analyzed. Particular emphasis is placed on current cartilage biomarkers, their diagnostic value and role in monitoring the efficiency of treatment in clinical trials. The paper provides a comparative analysis of detectable serum and urine biomarkers according to the results of the complex analysis made by the National Institutes of Health. Particular attention is given to cartilage oligomeric matrix protein (COMP. Foreign authors’ investigations suggest that there is a relationship between serum COMP levels and disease severity and joint X-ray changes. There is evidence for the efficacy of hyaluronic acid used in the treatment of secondary osteoarthritis in patients with RA.

    Full Text Available Rheumatoid Arthritis (RA is a widespread disease and its renal involvement, relatively common, is clinically significant because worsens course and mortality of the primary disease. There is still no agreement on the prevalence of renal disorders in RA: data analysis originates from different sources, as death certificates, autopsies, clinical and laboratory findings and kidney biopsies, each with its limitations. Histoimmunological studies on bioptical specimens of patients with RA and kidney damage, led to clarify prevalent pathologies. In order of frequency: glomerulonephritis and amyloidosis (60-65% and 20-30% respectively, followed by acute or chronic interstitial nephritis. Kidney injury during RA includes secondary renal amyloidosis, nephrotoxic effects of antirheumatic drugs and nephropathies as extra-articular manifestations (rheumatoid nephropathy. Amyloidosis affects survival, increases morbidity and is the main cause of end stage renal disease in patients with RA and nephropathy. Strong association between RA activity and amyloidosis needs the use of immunosuppressive and combined therapies, to prevent this complication and reduce risk of dialysis. Long-lasting and combined RA pharmacotherapy involves various renal side effects. In this review we describe NSAIDs and DMARDs (Disease-Modifying Antirheumatic Drugs nephrotoxicity, particularly by gold compounds, D-penicillamine, cyclosporine A and methotrexate. Rare cases of IgA glomerulonephritis during immunomodulating therapy with leflunomide and TNF blocking receptor (etanercept are reported; real clinical significance of this drug-related nephropathy will be established by development of RA treatment. In RA nephropathies, mesangial glomerulonephritis is the most frequent histological lesion (35-60 % out of biopsies from patients with urinary abnormalities and/or kidney impairment, followed by minimal change glomerulopathy (3-14% and p-ANCA positive necrotizing crescentic

    Full Text Available PURPOSE: To determine the relationship between the severity or stage of diabetic retinopathy and associated risk factors in a southern Brazilian population. METHODS: Transversal study of diabetic patients without previous ophthalmologic treatment, seen at a University eye clinic. These patients underwent fundus photography, complete blood work-up, systemic blood pressure measurement, urine analysis, and were questioned about risk factors previously determined by the authors. The presence or absence of risk factors was compared to the severity of diabetic retinopathy. RESULTS: Eighty-one patients were selected, 28 male, 53 female, 55 Caucasians, 26 African descendants, 28 had insulin-dependent diabetes mellitus, 53 had non-insulin-dependent diabetes mellitus. Factors related to more severe diabetic retinopathy include: insulin-dependent diabetes mellitus (a<0.01, nephropathy (a<0.05, proteinuria (a<0.05, duration of the disease (p<0.001, elevated fasting plasma glucose (p=0.11, glycosylated hemoglobin (HbA (1c (p=0.001, total serum cholesterol (p=0.019, lower hematocrit (p=0.004 and hemoglobin (p=0.001. CONCLUSIONS: The severity of diabetic retinopathy appears to be associated with risk factors such as duration of disease, type of diabetes, poor metabolic control, hemoglobin levels, total cholesterol and proteinuria. Factors apparently not related to severity of diabetic retinopathy include gender, age, systemic hypertension and hypomagnesemia.

    Full Text Available Drawing upon current socio-cultural understandings of risk, this study highlights the disjunction between the expert risk discourses that permeate official public health policy and practice, and young people’s own perspectives on health and risk. Data were collected from young people aged 14-16 years through the use of group and individual interviews in a school and community youth centre setting. Findings from this study question the saliency of expert-defined health-related risks to young people’s everyday lives. Young people in this study saw health as closely linked to ‘being happy’. Friendships and a sense of personal achievement were particularly important to participants’ health and well-being. When accounting for their participation in health-related practices identified as ‘risky’ in government policy – such as smoking, alcohol and substance use – young people emphasised the levels of pressure they experienced. Sources of pressure included arguments and bullying, school work, and negative stereotypes of young people in general. These areas indicated young people’s concerns that reach beyond the official prescriptions permeating current health policy.

  20. Building-related risk factors and work-related lower respiratory symptoms in 80 office buildings

    International Nuclear Information System (INIS)

    We assessed building-related risk factors for lower respiratory symptoms in office workers. The National Institute for Occupational Safety and Health in 1993 collected data during indoor environmental health investigations of workplaces. We used multivariate logistic regression analyses to assess relationships between lower respiratory symptoms in office workers and risk factors plausibly related to microbiologic contamination. Among 2,435 occupants in 80 office buildings, frequent, work-related multiple lower respiratory symptoms were strongly associated, in multivariate models, with two risk factors for microbiologic contamination: poor pan drainage under cooling coils and debris in outside air intake. Associations tended to be stronger among those with a history of physician-diagnosed asthma. These findings suggest that adverse lower respiratory health effects from indoor work environments, although unusual, may occur in relation to poorly designed or maintained ventilation systems, particularly among previously diagnosed asthmatics. These findings require confirmation in more representative buildings

    Full Text Available PURPOSES: To assess the risk factors of age-related macular degeneration in Argentina using a case-control study. METHODS: Surveys were used for subjects' antioxidant intake, age/gender, race, body mass index, hypertension, diabetes (and type of treatment, smoking, sunlight exposure, red meat consumption, fish consumption, presence of age-related macular degeneration and family history of age-related macular degeneration. Main effects models for logistic regression and ordinal logistic regression were used to analyze the results. RESULTS: There were 175 cases and 175 controls with a mean age of 75.4 years and 75.5 years, respectively, of whom 236 (67.4% were female. Of the cases with age-related macular degeneration, 159 (45.4% had age-related macular degeneration in their left eyes, 154 (44.0% in their right eyes, and 138 (39.4% in both eyes. Of the cases with age-related macular degeneration in their left eyes, 47.8% had the dry type, 40.3% had the wet type, and the type was unknown for 11.9%. The comparable figures for right eyes were: 51.9%, 34.4%, and 13.7%, respectively. The main effects model was dominated by higher sunlight exposure (OR [odds ratio]: 3.3 and a family history of age-related macular degeneration (OR: 4.3. Other factors included hypertension (OR: 2.1, smoking (OR: 2.2, and being of the Mestizo race, which lowered the risk of age-related macular degeneration (OR: 0.40. Red meat/fish consumption, body mass index, and iris color did not have an effect. Higher age was associated with progression to more severe age-related macular degeneration. CONCLUSION: Sunlight exposure, family history of age-related macular degeneration, and an older age were the significant risk factors. There may be other variables, as the risk was not explained very well by the existing factors. A larger sample may produce different and better results.

    Purpose: It has been the aim of the following study to evaluate pulmonary changes in rheumatoid arthritis with high-resolution CT and to assess their correlation with joint manifestation and laboratory paramters. Material and methods: The authors prospectively performed computed tomography (CT) in 83 patients with rheumatoid arthritis and graded pulmonary changes for frequency and severity. Included were patients with 6-7/7 ARA, BSR>25/1 min and mean disease duration of 12 years (range, 1-44). Data of medical and drug histories, smoking habits, blood levels of rheumatoid factor (RF), antinuclear antibodies (ANA) and C-reactive protein as well as the degree of joint involvement were taken into account. Results: 58 patients (70%) had pathological CT scans showing the following abnormalities: Interlobular thickening (44.5%), intralobular thickening (34%), nonseptal linear attenuation (35%), nodular or linear pleural thickening (32.5%), ground-glass pattern (19%), centrilobular nodules (13%), honeycombing (13%) and bronchiolectasis (9%). Intralobular thickening, honeycombing and pleural thickening were associated with a higher degree of joint manifestation; pleural thickening, honeycombing and ground-glass pattern were associated with a higher level of rheumatoid factor. There was no relationship between pulmonary changes and either the duration of the disease, antinuclear antibodies (ANA) or C-reactive protein. Conclusion: CT may be a useful noninvasive tool for recognition of RA-associated lung disease. Interstitial lung changes are frequent and they are independent of the duration of the disease. Pulmonary interstitial changes are more frequent and more severe in RF-positive patients and in case of more severe joint involvement. (orig.)

    It was investigated what blood disorders except leukemia increased the relative risk with dose dependency in atomic bomb survivors. Subjects were 217 patients of atomic bomb survivors in Hiroshima and Nagasaki, who had blood disorders except leukemia and died between 1950 and 1990. Their medical records were analyzed and their diagnoses were reevaluated. Sixteen cases were diagnosed as the aplastic anemia and 12 as the myelodysplastic syndrome (MDS). In the aplastic anemia, there was no correlation between the exposure dose and the mortality. In MDS, the excess relative risk (ERR)/bone marrow exposure dose of 1 Sv was very high (13.0). These results supports the hypothesis that MDS would be broken out by the clonal abnormality of the hematopoietic stem cell and radiation exposure could cause the appearance of the abnormal stem cell clone.

    Research on socioeconomic differences in overweight and obesity and on the ecological association between income inequality and obesity prevalence suggests that relative deprivation may contribute to lifestyle risk factors for obesity independently of absolute affluence. We tested this hypothesis using data on 25,980 adolescents (11-15 years) in the 2010 Canadian Health Behaviour in School-aged Children (HBSC) study. The Yitzhaki index of relative deprivation was applied to the HBSC Family Affluence Scale, an index of common material assets, with more affluent schoolmates representing the comparative reference group. Regression analysis tested the associations between relative deprivation and four obesity risk factors (skipping breakfasts, physical activity, and healthful and unhealthful food choices) plus dietary restraint. Relative deprivation uniquely related to skipping breakfasts, less physical activity, fewer healthful food choices (e.g., fruits, vegetables, whole grain breads), and a lower likelihood of dieting to lose weight. Consistent with Runciman's (1966) theory of relative deprivation and with psychosocial interpretations of the health consequences of income inequality, the results indicate that having mostly better off schoolmates can contribute to poorer health behaviours independently of school-level affluence and subjective social status. We discuss the implications of these findings for understanding the social origins of obesity and targeting health interventions. PMID:26851410

    Full Text Available Rheumatoid arthritis is a systemic autoimmune disease, mainly poli-artycular, among wide-spread chronic inflammatory diseases, that cause pain, functional limitation, damage and joints deformations, and disability. It is characterized by turns of active inflammation and remission phases. Inflammation degree and persistence are associated to a bad functional prognosis and progressive joint disability. These patients management require a continuous valuation of inflammatory activity index of disease both therapeutic management and to prevent disablement process. We focus on many valuation index of joint disability and functional damage. Very important are both the scales of auto-values concerning the pain and the joint swelling and clinical data get by physician to valuate activity index of disease as defined by DAS28. Significant data come by health-related quality of life, disability and by AIMS2 (Arthritis Impact Measurement Scale.

    In many theories of decision under risk (e.g., expected utility theory, rank-dependent utility theory, and prospect theory), the utility of a prospect is independent of other options in the choice set. The experiments presented here show a large effect of the available options, suggesting instead that prospects are valued relative to one another. The judged certainty equivalent for a prospect is strongly influenced by the options available. Similarly, the selection of a preferred prospect is ...

  12. Current concepts in psoriatic arthritis: pathogenesis and management.

    Science.gov (United States)

    de Vlam, Kurt; Gottlieb, Alice B; Mease, Philip J

    2014-11-01

    Psoriatic arthritis occurs in a subset of psoriasis patients and is therefore commonly encountered in dermatology practice. Although its exact pathogenesis is unknown, psoriatic arthritis is thought to share common mechanisms with psoriatic skin symptoms. Innate and adaptive immune responses are abnormally activated in psoriasis and may acquire the ability to attack peripheral joints and other sites following an environmental trigger (e.g. mechanical stress, trauma, infection) in genetically susceptible patients. The increased cardiovascular risk inherent in psoriasis appears further enhanced in psoriatic arthritis, likely reflecting the overall burden of systemic inflammation contributing to atherogenic processes. Basic research and clinical trials have suggested that tumour necrosis factor is important in psoriatic arthritis pathophysiology, and accumulating evidence suggests that Th17 cells and interleukin-17A may also be important. Basic research and clinical trials inform our understanding of psoriatic arthritis pathophysiology and, in turn, help dermatologists to make better treatment decisions. PMID:24573106

    Full Text Available Background and Objectives: Anthropometric variables and their relation to conventional coronary artery disease (CAD risk factors in railway employees have been inadequately studied in India. This cross-sectional survey was carried out in the Solapur division of the Central railway in the year 2004, to assess the anthropometric variables in railway employees and their relation to conventional CAD risk factors. Materials and Methods: A total of 995 railway employees, with 872 males and 123 females participated in this cross-sectional study. All subjects underwent anthropometric measurements, fasting lipid profile, and blood sugar level. Various anthropometric indices were calculated for body mass index (BMI, waist circumference (WC, waist-to-hip ratio (WHR, waist-to-height ratio (WHtR, and abdominal volume index (AVI. Statistical analysis was done by EPI Info 6 statistical software. Results: Compared to all other obesity indices, WHtR was most prevalent in both genders. High WHtR was present in 699 (80.16% males and 103 (83.73% females. Age ≥45 years, high systolic BP, high diastolic BP, low HDL, high triglyceride, and diabetes mellitus were positively correlated with high BMI, high WC, high WHR, high WHtR, and high AVI. High BMI, high WC, high WHR, high WHtR, and high AVI were negatively associated with physical inactivity. Conclusions: Over all, anthropometric variables in both genders were significantly deranged in subjects with coronary risk factors. Compared to all other anthropometric variables, WHtR was statistically significantly associated with a majority of coronary artery risk factors. Hence we recommend inclusion of WHtR as a parameter of obesity to predict coronary artery disease risk factor along with WC, WHR, and BMI in epidemiologic studies.

  14. Modelling the genetic risk in age-related macular degeneration.

    Felix Grassmann

    Full Text Available Late-stage age-related macular degeneration (AMD is a common sight-threatening disease of the central retina affecting approximately 1 in 30 Caucasians. Besides age and smoking, genetic variants from several gene loci have reproducibly been associated with this condition and likely explain a large proportion of disease. Here, we developed a genetic risk score (GRS for AMD based on 13 risk variants from eight gene loci. The model exhibited good discriminative accuracy, area-under-curve (AUC of the receiver-operating characteristic of 0.820, which was confirmed in a cross-validation approach. Noteworthy, younger AMD patients aged below 75 had a significantly higher mean GRS (1.87, 95% CI: 1.69-2.05 than patients aged 75 and above (1.45, 95% CI: 1.36-1.54. Based on five equally sized GRS intervals, we present a risk classification with a relative AMD risk of 64.0 (95% CI: 14.11-1131.96 for individuals in the highest category (GRS 3.44-5.18, 0.5% of the general population compared to subjects with the most common genetic background (GRS -0.05-1.70, 40.2% of general population. The highest GRS category identifies AMD patients with a sensitivity of 7.9% and a specificity of 99.9% when compared to the four lower categories. Modeling a general population around 85 years of age, 87.4% of individuals in the highest GRS category would be expected to develop AMD by that age. In contrast, only 2.2% of individuals in the two lowest GRS categories which represent almost 50% of the general population are expected to manifest AMD. Our findings underscore the large proportion of AMD cases explained by genetics particularly for younger AMD patients. The five-category risk classification could be useful for therapeutic stratification or for diagnostic testing purposes once preventive treatment is available.

    2012-06-01

    Full Text Available Epidemiological studies on psoriatic arthritis have long been hampered by the absence of widely accepted classification criteria. The development of the CASPAR (ClASsification criteria for Psoriatic ARthritis criteria has recently provided the framework for conducting epidemiological studies in psoriatic arthritis using uniform recruitment criteria. However, so far, only a minority of studies have adopted such criteria. In addition to the lack of shared classification criteria, differences in study settings, designs, and ascertainment methods have contributed to yield substantial disparities in the estimates of the incidence (from 3,02 to 23,1 cases per 100,000 people and prevalence (from 49,1 to 420 cases per 100,000 people of psoriatic arthritis around the globe. Overall, the available data suggests that the prevalence of psoriasis in the general population is approximately 2-3%, with about a third of patients with psoriasis having arthritis. Therefore, psoriatic arthritis may affect 0,3- 1,0% of the population, a frequency not dissimilar from that of rheumatoid arthritis. Future epidemiological studies should be carried out in larger numbers of patients diagnosed using consistent criteria.

    Objectives Rheumatoid arthritis (RA) is a prototypic chronic inflammatory disease with a debilitating course if untreated. A genetic predisposition for RA is known, and its occurrence is associated with the presence of autoantibodies in the serum and with environmental factors. It is unknown if smoking and overweight are contributory factors for developing RA in individuals with RA-specific autoantibodies in the serum. Methods Fifty-five individuals at risk for developing RA, based on the presence of RA-specific autoantibodies in the serum, who never had any evidence of arthritis upon physical examination, were followed over time. Smoking was assessed as being never or ever smoker and body mass index as <25 (normal) or ≥25 kg/m2 (overweight). Clinical endpoint was the occurrence of arthritis. Proportional hazard regression analysis was performed to investigate the potential of (combinations of) variables in predicting the onset of arthritis over time. Results After a median follow up time of 13 (IQR 6–27) months, 15 individuals (27%) developed arthritis. Smoking was associated with the development of arthritis (HR (95% CI): 9.6 (1.3 to 73.0); p=0.029). Overweight was, independently of smoking, associated with arthritis (HR (95% CI): 5.6 (1.3 to 25.0); p=0.023). The overall arthritis risk of 28% after a median of 27 months follow up increased to 60% in individuals with a smoking history combined with overweight. Conclusions This is the first prospective study showing that smoking and overweight increase the risk of development of arthritis in a cohort of autoantibody-positive individuals at risk for developing RA. These results show the importance of life style factors in development of RA and should be critically evaluated in future clinical research aimed at disease prevention. PMID:23104761

    The format in which risk information is presented has a fundamental influence on the quality of risk communication with health consumers. Graphic formats might enhance the risk communication process, but we know little about how these formats affect risk-related behavior. Based on a review of literature within and outside the medical domain, we present four useful frameworks for evaluating the effects of graphic format on risk-related behavior.

  19. Arthritis in the buff

    International Nuclear Information System (INIS)

    Understanding the significance of radiologic perturbations in articular diseases is facilitated by correlation with its representation in intact macerated skeletons (from the collections of the Cleveland Museum of Natural History). Classic skeletal involvement is illustrated grossly and radiographically for the following conditions: rheumatoid arthritis calcium pyrophosphate deposition disease, osteoarthritis, ankylosing spondylitis, reactive (Reiter syndrome, psoriatic arthritis) diffuse idiopathic skeletal hyperostosis, and infectious arthritis. Distribution and lesion character is reviewed. Visualization of the gross bone lesion ''in the buff'' provides clear explanation of its radiologic appearance and facilitates the transition from x-ray image to the pathophysiology proposed in the interpretation

    In Malaysia technologically enhanced naturally occurring radioactive materials (TENORM) wastes are mainly the product of the oil and gas industry and mineral processing. Among these TENORM wastes are tin tailing, tin slag, gypsum and oil sludge. Mineral processing and oil and gas industries produce large volume of TENORM wastes that has become a radiological concern to the authorities. A study was carried out to assess the radiological risk related to workers working at these disposal sites and landfills as well as to the members of the public should these areas be developed for future land use. Radiological risk was assessed based on the magnitude of radiation hazard, effective dose rates and excess cancer risks. Effective dose rates and excess cancer risks were estimated using RESRAD 6.4 computer code. All data on the activity concentrations of NORM in wastes and sludges used in this study were obtained from the Atomic Energy Licensing Board, Malaysia, and they were collected over a period of between 5 and 10 y. Results obtained showed that there was a wide range in the total activity concentrations (TAC) of nuclides in the TENORM wastes. With the exception of tin slag and tin tailing-based TENORM wastes, all other TENORM wastes have TAC values comparable to that of Malaysia's soil. Occupational Effective Dose Rates estimated in all landfill areas were lower than the 20 mSv y(-1) permissible dose limit. The average Excess Cancer Risk Coefficient was estimated to be 2.77×10(-3) risk per mSv. The effective dose rates for residents living on gypsum and oil sludge-based TENORM wastes landfills were estimated to be lower than the permissible dose limit for members of the public, and was also comparable to that of the average Malaysia's ordinary soils. The average excess cancer risk coefficient was estimated to be 3.19×10(-3) risk per mSv. Results obtained suggest that gypsum and oil sludge-based TENORM wastes should be exempted from any radiological regulatory

    Full Text Available The article deals with the issue of psychic problems of rheumatoid arthritis patients. Rheumatoid arthritis is a chronic, inflammatory motor system disease with comprehensive impact on the patient's life. The disease is often considered an exclusively physical disease. But such approach is insufficient because the disease is accompanied by motor limitations of different intensities, by pain and by fatigue that cause considerable exhaustion to the patient. The patients often must give up their hobbies and in some cases even their jobs. In most serious cases, even common daily activities including self-servicing actions become an obstacle to the patient. It is therefore logical that the psyche of a patient with such disease is considerably strained. One of the partial goals of the study consisted in mapping the subjectively perceived quality of life of rheumatoid arthritis patients in facet 8, "negative feelings", and in ascertaining whether there is statistically significant relation to facets 1, "pain and discomfort", and 2, "energy and fatigue". Another goal consisted in comparing the subjectively perceived quality of life between men and women with rheumatoid arthritis, as well as between population of rheumatoid arthritis patients and control healthy population. The study was implemented within the research project of the Grant Agency of the University of South Bohemia in České Budějovice number 120/2012/S, "Reflection of quality of life in nursing", under use of two standardized questionnaires, WHOQOL-100 and HAQ. This article presents exclusively the data acquired based on the WHOQOL-100 questionnaire. The research set consisted of patients suffering from rheumatoid arthritis from all over the Czech Republic.

    Full Text Available Genetic variations, such as single nucleotide polymorphisms (SNPs in microRNAs (miRNA or in the miRNA binding sites may affect the miRNA dependent gene expression regulation, which has been implicated in various cancers, including breast cancer, and may alter individual susceptibility to cancer. We investigated associations between miRNA related SNPs and breast cancer risk. First we evaluated 2,196 SNPs in a case-control study combining nine genome wide association studies (GWAS. Second, we further investigated 42 SNPs with suggestive evidence for association using 41,785 cases and 41,880 controls from 41 studies included in the Breast Cancer Association Consortium (BCAC. Combining the GWAS and BCAC data within a meta-analysis, we estimated main effects on breast cancer risk as well as risks for estrogen receptor (ER and age defined subgroups. Five miRNA binding site SNPs associated significantly with breast cancer risk: rs1045494 (odds ratio (OR 0.92; 95% confidence interval (CI: 0.88-0.96, rs1052532 (OR 0.97; 95% CI: 0.95-0.99, rs10719 (OR 0.97; 95% CI: 0.94-0.99, rs4687554 (OR 0.97; 95% CI: 0.95-0.99, and rs3134615 (OR 1.03; 95% CI: 1.01-1.05 located in the 3' UTR of CASP8, HDDC3, DROSHA, MUSTN1, and MYCL1, respectively. DROSHA belongs to miRNA machinery genes and has a central role in initial miRNA processing. The remaining genes are involved in different molecular functions, including apoptosis and gene expression regulation. Further studies are warranted to elucidate whether the miRNA binding site SNPs are the causative variants for the observed risk effects.

    Rheumatoid arthritis (RA)-related pulmonary disorders specifically airway abnormalities and interstitial pneumonia (IP) are important extra-articular manifestations. The forced oscillation technique (FOT) is a useful method to assess respiratory impedance, respiratory resistance (Rrs) and reactance (Xrs), at different oscillatory frequencies during tidal breathing. The aim of this study was to characterize the respiratory mechanics of patients with RA and to relate them to parameters of the pulmonary function test and findings of chest CT images. Respiratory impedance of RA patients (n = 69) was measured as a function of frequency from 4 to 36 Hz using the FOT device and compared with that of healthy subjects (n = 10). Data were retrospectively reviewed. Patients were female-dominant (60.9 %) and 95.7 % had abnormal CT findings including airway and parenchymal abnormalities. Thirty-seven of 69 patients (53.6 %) were smokers. Rrs was significantly frequency-dependent in RA patients but not in the healthy subjects. Xrs were significantly frequency-dependent in both RA and healthy groups. Rrs was significantly higher during an expiratory phase in both RA and healthy groups. Xrs was significantly lower (more negative) during an expiratory phase than that during an inspiratory phase in RA patients but not in healthy subjects. Xrs of the RA group was significantly more negative than that of the normal control. There was no difference in impedance parameters between the airway lesion dominant (n = 27) and IP dominant groups (n = 23) in the RA group. The impedance parameters of the RA group significantly correlated with most parameters of the pulmonary function test. In pulmonary function test results, % of the predicted value for forced expiratory flow from 25 to 75 % of forced vital capacity was significantly lower and % of the predicted value for diffusing capacity of the lung for carbon monoxide was higher in the airway lesion dominant group than those in

    Human immunodeficiency virus (HIV) is often contracted through engaging in risky reward-motivated behaviors such as needle sharing and unprotected sex. Understanding the factors that make an individual more vulnerable to succumbing to the temptation to engage in these risky behaviors is important to limiting the spread of HIV. One potential source of this vulnerability concerns the degree to which an individual is able to resist paying attention to irrelevant reward information. In the present study, we examine this possible link by characterizing individual differences in value-based attentional bias in a sample of HIV+ individuals with varying histories of risk-taking behavior. Participants learned associations between experimental stimuli and monetary reward outcome. The degree of attentional bias for these reward-associated stimuli, reflected in their ability to capture attention when presented as task-irrelevant distractors, was then assessed both immediately and six months following reward learning. Value-driven attentional capture was related to substance abuse history and non-planning impulsiveness during the time leading up to contraction of HIV as measured via self-report. These findings suggest a link between the ability to ignore reward-associated information and prior HIV-related risk-taking behavior. Additionally, particular aspects of HIV-associated neurocognitive disorders were related to attentional bias, including motor deficits commonly associated with HIV-induced damage to the basal ganglia.

  15. Complementary medicine in rheumatoid arthritis

    Directory of Open Access Journals (Sweden)

    2011-09-01

    Full Text Available Use of complementary and alternative medicine (CAM for chronic conditions has increased in recent years. CAM is immensely popular for musculoskeletal conditions and patients suffering from rheumatoid arthritis (RA frequently try CAM. This review summarises the trial data for or against CAM as a symptomatic treatment for rheumatoid arthritis. Collectively the evidence demonstrates that some CAM modalities show significant promise, e.g. acupuncture, diets, herbal medicine, homoeopathy, massage, supplements. However, for the great majority of these therapies no evidencebased (clinical randomized trials results are available. CAM is usually used in addition to, and not as a substitute for conventional therapies. The motivation of patients to try CAM is complex; the willingness to take control of their healthcare, the desire to try everything available, the mass-media pressure and the erroneous notion that CAM is without risks. In fact, none of these treatments is totally devoid of risks. While the use of complementary and alternative modalities for the treatment of RA continues to increase, rigorous clinical trials examining their efficacy are needed before definitive recommendations regarding the application of these modalities can be made.

    Full Text Available In this paper, expected utility, defined by a Taylor series expansion around expected wealth, is maximized. The coefficient of relative risk aversion (CRRA that is commensurate with a 100% investment in the risky asset is simulated. The following parameters are varied: the riskless return, the market standard deviation, the market stock premium, and the skewness and the kurtosis of the risky return. Both the high extremes and the low extremes are considered. With these figures, the upper bound of the market CRRA is 3.021 and the lower bound is 0.466. Log utility, which corresponds to a CRRA of 1, is not excluded.

    2015-10-01

    Dengue is a mosquito-transmitted viral infection of major international public health concern. Global environmental and socio-economic change has created ideal conditions for the global expansion of dengue transmission. Innovative modelling tools help in understanding the global determinants of dengue risk and the relative impact of environmental and socio-economic factors on dengue transmission and spread. While climatic factors may act as a limiting factor on the global scale, other processes may play a dominant role at the local level. Understanding the spatial scales at which environmental and socio-economic factors dominate can help to target appropriate dengue control and prevention strategies. PMID:26311416

  19. Nuclear fuel cycle risk assessment: survey and computer compilation of risk-related literature

    International Nuclear Information System (INIS)

    The US Nuclear Regulatory Commission has initiated the Fuel Cycle Risk Assessment Program to provide risk assessment methods for assistance in the regulatory process for nuclear fuel cycle facilities other than reactors. Both the once-through cycle and plutonium recycle are being considered. A previous report generated by this program defines and describes fuel cycle facilities, or elements, considered in the program. This report, the second from the program, describes the survey and computer compilation of fuel cycle risk-related literature. Sources of available information on the design, safety, and risk associated with the defined set of fuel cycle elements were searched and documents obtained were catalogued and characterized with respect to fuel cycle elements and specific risk/safety information. Both US and foreign surveys were conducted. Battelle's computer-based BASIS information management system was used to facilitate the establishment of the literature compilation. A complete listing of the literature compilation and several useful indexes are included. Future updates of the literature compilation will be published periodically. 760 annotated citations are included

  20. Energy use and related risk management problems in CEE countries

    International Nuclear Information System (INIS)

    Nowadays, the efficiency of energy use in the Central and East-European (CEE) countries is insufficient, being much lower than in the 'Old Europe'. The problem becomes increasingly pressing due to non-stop increasing prices of energy carriers (especially of crude oil). The authors trace the development of research activities in this sphere, classifying the revealed changes in parameters of energy consumption processes in particular time intervals into deterministic, probabilistic, and fuzzy. The paper presents a thorough analysis of decision-making in the energy management at its different levels normative, strategic, and operative. Particular attention is given to the management under uncertainty conditions - i.e. to the risk management. The most wanted research directions in this area proposed by the energy and environment policy (EEP) Center specially created for CEE countries concern management under risk connected with innovations, international activities, loss of reputation, etc.. The authors consider in detail the risk management with insufficient knowledge (non-knowledge) and under chaos. Much consideration is given to the scenario management and the game theory principles as related to the sphere of energy use. (Authors)

    2007-04-15

    Purpose: To find magnetic resonance (MR) findings predicting cement leakage in patients receiving percutaneous vertebroplasty (PVP) due to osteoporotic compression fractures. Material and Methods: MR was done in 43 patients (age 52-89 years) before PVP (56 vertebrae), which was done via a bipedicular approach with fluoroscopic monitoring. Shortly after the procedure, a non-contrast-enhanced computed tomography (CT) scan was done at the vertebroplasty sites for evaluation of bone cement leakage. The following MR findings of fractured vertebral bodies were retrospectively reviewed for correlation with leakage risk: severity of bone-marrow edema, presence of a T2-weighted low-signal-intensity line, percentage residual vertebral body height, presence of either a vacuum or cystic change within the vertebral body, and presence of a cortical disruption. Results: After PVP, cement leakage was detected in 35 vertebrae (62.5%). Leakage was most frequently observed in the anterior external vertebral venous plexus (46%). Cement leakage rate increased when there was a cortical disruption (P = 0.037), especially at the endplates, while it decreased when there was a vacuum or a cystic change within the fractured vertebra (P 0.019). Other MR findings were not related to the risk of cement leakage. Conclusion: The risk of cement leakage in PVP increases when MR shows cortical disruption in a fractured vertebral body, especially at the endplates. It decreases when MR shows a vacuum or cystic change within the body. Keywords Cement leakage, MR imaging, spine, vertebroplasty.

  2. Nanotechnology, risk, and oversight: learning lessons from related emerging technologies.

    Emerging technologies are defined by their novelty and thus are accompanied by significant uncertainty in determining appropriate ways to manage risks associated with them. Yet, there is a body of prior knowledge about risk management and oversight policy for other technologies that have already permeated society. Here, we describe two ways in which prospective oversight policy analysis for emerging technologies can draw upon these past experiences. One involves comparing specific products that have already been marketed to similar products of the emerging technology (cognate-product approach). The other treats the emerging technology as a body of products and methods and relates it to another technological field that has already emerged and penetrated markets (whole-technology approach). In this article, we describe our work using these approaches to inform risk and oversight policy for nanotechnology and its products. We draw parallels between biotechnology and nanotechnology as whole fields of development and also between genetically engineered organisms in the food supply and agricultural products of nanotechnology. Through these comparisons, we find that both approaches to historical learning have value and present lessons that could be applied to nanotechnology. PMID:20723152

    Background: The effects of the risk factors of ischemic heart disease (IHD) and stroke on the occurrence of these diseases differ between different populations. Objectives: To study the difference in the effects of different cardiovascular (CVD) risk factors on the incidence of IHD and stroke in an Iranian adult population. Patients and Methods: The Isfahan Cohort Study (ICS) is a longitudinal study that followed up 6323 subjects older than 35 years with no history of CVD since 2001. Of the original sample, only 5431 participants were contacted and followed up until 2011. The end points were the occurrence of IHD (defined as fatal and non-fatal myocardial infarction, unstable angina, and sudden cardiac death) and stroke. After 10 years of follow-up, 564 new cases of IHD and 141 new cases of stroke were detected. The relative risks (RRs) of cardiometabolic risk factors such as hypertension, diabetes, hypercholesterolemia, hypertriglyceridemia, high low-density lipoprotein cholesterol (LDL-C) level, low high-density lipoprotein cholesterol (HDL-C) level, current smoking, obesity, high waist-to-hip ratio, family history of CVD, and metabolic syndrome were compared between IHD and stroke patients. The ratio of relative risks (RRR) was calculated for comparing two RRs and estimated adjusted RRR was calculated by using generalized linear regression with a log link and binomial distribution. Results: The RRs of the occurrence of IHD and stroke in diabetic patients were 1.94 and 3.26, respectively, and the difference was statistically different (P = 0.016). The RR of high LDL-C was significantly higher for IHD than for stroke (P = 0.045), while all the other risk factors showed similar RRs for IHD and stroke, with no significant difference in their RRR, including hypertension. Diabetes and hypertension had the highest RRs for IHD, followed by diabetes, metabolic syndrome, and hypertension for stroke. Conclusions: The effect of diabetes mellitus on stroke was more

    Strategies and measures for disaster risk reduction (DRR) are not being implemented at the scale called for by the Hyogo Framework of Action. Part of the problem is that, from the perspective of decision makers with resource constraints, it is risky to invest in something that reaps benefits only in the case of a relatively unlikely event (such as a hurricane or a drought). People and institutions are understandably prone to invest in choices that yield less uncertain benefits. DRR, in itself...

  8. Dust related risks of clinically relevant lung functional deficits

    The aim was to quantify the risks of clinically important deficits of FEV1 in coal miners in relation to cumulative and average concentrations of respirable dust. Data were studied from over 7000 men who had been surveyed in the late 1970s. Linear regression equations for the association between FEV1 and self-reported breathlessness on mild exertion were used to define clinically important levels of FEV1 deficit, and the probabilities that individuals with different dust exposures would experience these deficits were calculated. Levels of FEV1 were lower among breathless men than among others, with a large overlap of the distributions. The relations between standardised FEV1 and breathlessness were constant over all age and smoking groups. FEV1 deficits of 20.367, 20.627, and 20.993 I (designated as 'small', 'medium', and 'large' deficits) were, on average, associated with proportional increases of risks of breathlessness by factors of 1.5, 2.0, and 3.0 respectively. Cumulative respirable dust exposure ranged up to 726 gh/m{sup 3}, mean 136 gh/m{sup 3} (British Medical Research Council measurement convention). An increase of 50 gh/m{sup 3} was associated with an increase of about 2% in the proportion of men with small deficits in FEV1. For medium deficits the increases ranged from 1.5% to 2%, depending on age. A similar pattern was seen for large deficits, but with smaller increases. In the unlikely event of continuous exposure at the proposed new maximum respirable dust limit for British mines of 3 mg/m{sup 3} (ISO-CEN measurement convention) for a working lifetime, the risk of a medium deficit of FEV1 for a non-smoker at age 60 would be estimated to be 34%, compared with 25% for zero dust exposure; for smokers, about 54% compared with 44%.

  10. Time Dependent Relative Risks in Life Insurance Medical Underwriting.

    Science.gov (United States)

    Kneepkens, Robert F

    2015-01-01

    Introduction .- Life insurance medicine focuses on mortality hazards in specified periods. People are free to insure their lives for shorter or longer terms. Because the chosen terms range from 1 year to a life time, life insurers have to take into account the fact that the predictive value of risk indicators can and will change over time. The time a risk indicator keeps its predictive value, will be dependent on its biological effects, volatility, and treatability. For a given applicant this implies that the relative hazard (RH) calculated for his/her medical condition should be dependent on the term of the insurance. The main objective of this study is to determine if some commonly used risk indicators - previously used to study age dependency of relative risks - have a predictive value that increases with the observation period. (1) Methods .- This population-based cohort study uses NHANES-data files from the Third National Health and Nutrition Examination Survey (NHANES III) and the NHANES Linked Mortality Files 2010. Only participants aged 20 to 69 that were examined in mobile examination centers, without a history of some prevalent high risk diseases were included. The observed mortality was compared to the expected mortality in a Generalized Linear Model (GLM) with Poisson error structure with two reference populations, which both can serve as preferred reference for life insurers: The United States Life Tables 2008 (USLT) and the 2008 Valuation Basic Tables (VBT) based on the insured population of 35 US Life insurers. The time dependency of the RHs of the systolic blood pressure (SBP), aspartate aminotransferase (ASAT), lactate dehydrogenase (LDH), serum albumin and albuminuria, was assessed, with correction for ethnicity, household income, history of diabetes mellitus, BMI and serum cholesterol. To be able to compare the results with the results of the Age Dependency Study (ADS), the same data, risk indicators, statistical analysis method, and the

In the patients aged >65 years, the safety profile (defined as rate of side effects of etanercept was similar to that in patients aged ≤65 years (P > 0.05 and the survival curves between the groups were similar (P > 0.05.Conclusions: In our three-year experience, the anti-TNFα agent etanercept has been well tolerated and safe in elderly patients. The risk of side effects in these patients was no greater than in subjects aged ≤65 years. However, such inhibitors are associated with various and numerous side effects and elderly patients with RA should be carefully monitored to limit the risk of side effects during anti-TNFα therapy as much as possible.Keywords: anti-TNF therapy, rheumatoid arthritis, elderly

  18. Exposure of workers to the risks related to electromagnetic fields. Guide for risk assessment

    International Nuclear Information System (INIS)

    This guide aims at helping companies to prevent risks related to worker exposure to electromagnetic fields, and at simplifying the assessment approach. After some generalities of electromagnetic fields (notions of electromagnetic spectrum, electric, magnetic and electromagnetic fields, wavelength and frequency, reactive near- or far-field area, work environment), this report describes the effect of an exposure with respect to frequencies (under 100 khz, over 10 MHz, between 100 khz and 10 MHz), recalls the regulation in occupational environment. It presents some generalities on exposure sources, and methods and ways for a simplified risk assessment (equipment inventory and characterization, CE-labelled equipment). It addresses various aspects of a deepened risk assessment: the exposure assessment (emitted field measurement, workstation analysis, maximum exposure, determination of exposure action level or VDA), the indirect effects (contact with a metallic object within the field, projection of ferromagnetic objects, initiation of firing electric devices, fires and explosions), and workers with specific risks (those bearing active implants or passive ferromagnetic implants, pregnant women). The last part addresses actions aimed at reducing the exposure. Eight industrial applications are more particularly addressed and discussed at the end of each chapter: induction-based devices (welding, fusion, heating, surface treatment, so on), magnetizers and demagnetizers, magneto-scopic devices, magnetic resonance imagery devices, electrolytic cells, heating or welding devices based on dielectric losses, and microwave ovens

  20. School-related risk and protective factors associated with truancy among urban youth placed at risk.

    Science.gov (United States)

    Henry, Kimberly L; Huizinga, David H

    2007-11-01

    Truancy is a serious concern in the United States. Its negative effects are so pervasive that in 2003 the Office of Juvenile Justice and Delinquency Prevention named truancy prevention a national priority. Effective prevention of truancy requires a thorough understanding of the characteristics that describe truant youth as well as factors that may put them at risk for truancy. Unfortunately, surprisingly little is known about the correlates and/or causes of truancy. In this paper we explore associations between truancy and several salient school-related risk and protective factors among a sample of youth who grew up in socially disorganized neighborhoods of Denver, CO. We demonstrate that several school-related risk and protective factors are associated with truancy. Perhaps most importantly, we identify that the two most robust predictors are school performance and involvement with delinquent peers, and that these two variables form a synergistic relationship in which the relationship between delinquent peer association and truancy is mitigated among students who perform well in school. EDITORS' STRATEGIC IMPLICATIONS: The authors use data from a large probability sample drawn from neighborhoods with high crime rates to identify key correlates of truancy. They also draw attention to the dearth of efficacious truancy prevention efforts in spite of the magnitude of the problem. PMID:18004658

  2. Demographic And Risk Factors Related To Military Tuberculosis

    Directory of Open Access Journals (Sweden)

    M. Rasolinejad

    2006-05-01

    Full Text Available Background and Aim: Tuberculosis is one the major health care problems in developing countries. Miliary tuberculosis is induced by blood dissemination of multiple tubercle bacilli, the paramount importance of accurate diagnosis of military tuberculosis is because of its dismal outcome if untreated and the chance of cure if diagnosis happens early in the course of the disorder. In this study we describe the demographic and risk factors related to military tuberculosis, which enables us to control and reduce the incidence of military tuberculosis. This ultimately reduces the mortality and morbidity consistent with this disorder. Materials and Methods: we conducted a retrospective case control study, which compares 28 patients with military tuberculosis and 56 patients with pulmonary tuberculosis as control. We reviewed all the patients' documents registered between years 1994-2004, after extracting raw data we analyzed them with chi-square and Fisher exact tests. Results and Conclusion: We found that HIV (P< 0.05 infection and lack of BCG vaccination (P< 0.05 increases the number of military tuberculosis among our patients. In addition we did not find any other significant risk factor.

    In those severe-accident scenarios in which the primary vessel fails, high-temperature core debris falls into the reactor cavity where it interacts with structural concrete. This presentation outlines three aspects of core-concrete interaction analysis that must be considered in the prediction of radiological source terms: (1) the risk-related physical and chemical phenomena, (2) the NRC computer codes, CORCON and VANESA, used to predict the source-term and containment-loading parameters, and (3) possible causes of uncertainties in code predictions. Finally, to illustrate the range of problems encountered in determining code prediction uncertainties, a number of sensitivity studies and code comparisons with experimental data are reviewed

  8. Risk factors for age-related maculopathy are associated with a relative lack of macular pigment.

    2007-01-01

    Macular pigment (MP) is composed of the two dietary carotenoids lutein (L) and zeaxanthin (Z), and is believed to protect against age-related maculopathy (ARM). This study was undertaken to investigate MP optical density with respect to risk factors for ARM, in 828 healthy subjects from an Irish population. MP optical density was measured psychophysically using heterochromatic flicker photometry, serum L and Z were quantified by HPLC, and dietary intake of L and Z was assessed using a validated food-frequency questionnaire. Clinical and personal details were also recorded, with particular attention directed towards risk factors for ARM. We report a statistically significant age-related decline in MP optical density (r2=0.082, p<0.01). Current and past smokers had lower average MP optical density than never smokers and this difference was statistically significant (p<0.01). Subjects with a confirmed family history of ARM had significantly lower levels of MP optical density than subjects with no known family history of disease (p<0.01). For each of these established risk factors, their statistically significant negative association with MP persisted after controlling for the other two, and also after controlling for other potentially confounding variables such as sex, cholesterol, dietary and serum L (p<0.01). In the absence of retinal pathology, and in advance of disease onset, the relative lack of MP seen in association with increasing age, tobacco use and family history of ARM supports the hypothesis that the enhanced risk that these variables represent for ARM may be attributable, at least in part, to a parallel deficiency of macular carotenoids.

  12. On accounting difficulties: risks related to nuclear power

    International Nuclear Information System (INIS)

    An extreme risk has a very slight probability but potentially heavy consequences. Despite the existence of 3 accountancy methods for dealing with them (provisions, contingent liabilities and insurance), the transposition of such risks into financial statements is based on a sequential analysis of both the probability of the risk happening and the ability to estimate the effects. This method keeps us from taking into account risks with a highly uncertain probability of occurrence, such as accidents at nuclear power plants - independently of the 'amount' at stake. As management reports from firms concerned by nuclear risks show, the diffusion of qualitative information does not offset this gap in bookkeeping. (authors)

    Full Text Available Kate McAllister, Stephen Eyre, Gisela OrozcoArthritis Research United Kingdom Epidemiology Unit, Manchester Academic Health Science Centre, University of Manchester, UKAbstract: The study of complex genetics in autoimmune diseases has progressed at a tremendous pace over the last 4 years, as a direct result of the enormous gains made by genome wide association studies (GWAS. Novel genetic findings are continuously being reported alongside the rapid development of genetic technologies, sophisticated statistical analysis, and larger sample collections. It is now becoming clear that multiple genes contribute to disease risk in many complex genetic disorders including rheumatoid arthritis (RA and that there are common genetic risk factors that underlie a spectrum of autoimmune diseases. This review details the current genetic landscape of RA, and describes what GWAS has taught us in terms of missing heritability, subsets of disease, existence of genetic heterogeneity, and shared autoimmune risk loci. Finally, this review addresses the initial challenges faced in translating the wealth of genetic findings into determining the biological mechanisms that contribute to the relationship between genotype and phenotype. Unraveling the mechanism of how genes directly influence the cause of RA will lead to a better understanding of the disease and will ultimately have a direct clinical impact, informing the development of new therapies that can be utilized in the treatment of RA.Keywords: rheumatoid arthritis, GWAS, fine mapping, immunochip, bioinformatics

    Over the past several years, an increased understanding of the pathophysiology of psoriasis and psoriatic arthritis (PsA) has led to the development of several new biologic therapies. Appropriate treatment selection and timing may slow, and even halt, the progression of psoriasis and PsA; as a result, it can decrease the economic burden. As treatment options vary based on individual disease characteristics and patient preferences, reviewing the patient's complete clinical picture is imperative. An updated treatment algorithm, based on patients' most severe disease domain, is now available to guide the selection of optimal therapy. Special care should be given to patients with both psoriasis and PsA who experience multiple disease domains, a heavy symptom burden, and an increased risk of comorbidities. PMID:27356194

    aggressive floods in 1500-1800 era, and actual added trends of "climate change" are towards higher temperatures, less water and higher perturbations. These long term risks are rather poorly predictable and will be handled mostly by improvements in agriculture and also by social and economic adaptations, but at shorter delays and specific areas active policies are possible and exist. An agribusiness can set his production plans lowering his global risk. Sometimes it might use prudently some financial instruments, such as "orange juice futures". When using decision making models, some utility functions may consider that severe losses have higher effects than good profits, letting ranges for business margins for insurers to be limited by concurrence at correct levels. Correct availability of credits is necessary for bad periods, and also state policies for rare bad situations, concerning agribusiness survival and also alimentary safety. Insurance products are effective aids for a growing variety of well definite natural risks, such as in cases of hailstorm, that have probabilities of occurrence measurable from previous events data, and a variety of adequate professional models are continuously made for them. Related to Universidad Politecnica de Madrid the CEIGRAM institute has started recently and is involved in agricultural insurance, being connected with insurers through ENESA and AGROMUTUA. That world is active, important, evolving, and is regulated by diverse laws.

It is determined by some factors and it is the most important predictive index of infantile mortality. Objective: identifying the risk factors related to low birth weight. Methods: a descriptive study was conducted. There were analyzed the 77 birth of children with inferior weigh to 2500g, occurred in 2010 at the municipality of Cienfuegos, puerperas were included, mothers of those children. The pregnancy's follow-up cards, patient’s clinical records and municipal and provincial statistics were checked. In addition to the socio-demographic characteristics, the nutritional state, numbers of pregnancies, heavy profit during pregnancy, age, toxic habits and diseases correlated to pregnancy were analyzed. Results: the index of low birth weigh oscillated between 3.6 and 6.7 per month. The 52% of low birth weight newborn’s mothers had school university level. The 74 % of mothers work. The 70.1 % were smokers and the 57, 1 % developed a gravidum hypertensive disease. Conclusions: the most associated factors to low birth weight were, the mother’s habit to smoke, as well as the diseases that affected them during pregnancy, fundamentally the hypertensive disease and the vaginal sepsis.

  20. Relative risk site evaluations for Yakima Training Center

    Energy Technology Data Exchange (ETDEWEB)

    Smith, R.M.; Whelan, G.

    1996-11-01

    All 20 U.S. Army Yakima Training Center (YTC) sites evaluated were given a `low` relative risk. At Solid Waste Management Unit (SWMU) 22, a `minimum` soils contaminant hazard factor was assigned even though 6,700 mg/kg TPH-diesel was found in surface soil. SWMU 22 is physically located on top of and with the fence surrounding Area of Concern (AOC) 4. Because the diesel is most likely associated with AOC 4, and plans are to clean up AOC 4, any further actions regarding these contaminated soils should be addressed as part of the planned actions for AOC 4. Contaminant hazard factors of `moderate` were assigned to the soil pathway for SWMUs 4 and 7 because dieldrin and arsenic, respectively, were found in surface soil samples at concentrations exceeding standards. A `moderate` contaminant hazard factor was also assigned to the sediment pathway for AOC 1 because arsenic detected in sediments in `Larry`s Swimming Pool` exceeded the standard. All other contaminant hazard factors were rated as minimal. The receptor factor for all sites and pathways was rated `limited,` except for SWMU 54 in which the groundwater receptor factor was rated `potential.` A `potential` rating was assigned to the groundwater pathway at this site to be conservative. The site is located on the south side of the syncline axis where the unconfined aquifer may be present and there are no monitoring wells at the site to confirm or deny the presence of groundwater contamination.

  1. Review of studies related to uncertainty in risk analsis

    International Nuclear Information System (INIS)

    The Environmental Protection Agency's Office of Radiation Programs (ORP) is responsible for regulating on a national level the risks associated with technological sources of ionizing radiation in the environment. A critical activity of the ORP is analyzing and evaluating risk. The ORP believes that the analysis of uncertainty should be an integral part of any risk assessment; therefore, the ORP has initiated a project to develop framework for the treatment of uncertainty in risk analysis. Summaries of recent studies done in five areas of study are presented

    The flooding risk has always been considered to be very important for the risk safety management of dams. The extreme flooding downstream of a dam could be either due to dam failure or sometimes it can occur without failure. In both cases, it poses serious risks to people and property downstream of the dam. In this study, the risk assessment for the Jhelum river valley downstream of Mangla dam has been carried out. Mangla dam is one of the large earth and rock-fill dams in the world. The hei...

    Full Text Available Imaging of psoriatic arthritis (PsA is important for two reasons: the differential diagnosis from other arthritides and the assessment of structural damage that can be inhibited by the new drugs such as the anti-TNFα agents. Plain film radiographic findings of peripheral arthritis have been important in elaborating the concept of PsA as a separate disease entity. Characteristic aspects of psoriatic peripheral arthritis help the differentiation from rheumatoid arthritis. High-resolution ultrasonography (US, US combined with power Doppler (PDUS and magnetic resonance imaging (MRI can be used to image joint synovitis of PsA. Radiologic features of spondylitis associated with psoriasis are similar to spondylitis associated with reactive arthritis and differ from those of primary ankylosing spondylitis (AS and the spondylitis associated with inflammatory bowel disease. MRI is very sensitive for the early diagnosis of sacroiliitis. There have been no MRI studies on the spine of patients with PsA. In primary AS bone oedema in the vertebral bodies is an indicator of active disease and can ameliorate during anti-TNFα therapy. Historically, plain film radiography have played a pivotal role in defining enthesitis lesions of SpA. However, entheseal bone changes appear late. US and MRI have proved to be a highly sensitive and non invasive tools. Recent US and MRI studies on both finger and toe dactylitis have established that dactylitis is due to flexor tenosynovitis and marked adjacent soft tissue swelling with a variable degree of small joint synovitis. There is no evidence of enthesitis of the insertion of the flexor digitorum tendons and of the attachment of the caspsule of the digit joints.

  6. Septic arthritis of the pubic symphysis: an atypical abdominal pain.

    2015-02-01

    Septic arthritis of the pubic symphysis is a rare infection mostly caused by Staphylococcus aureus, and is traditionally associated with risk factors (sports, female incontinence surgery). Typical features of pubic symphysis infection include abdominal, pelvic, or groin pain that increases upon standing and walking, causing limping to occur. Acute onset of fever is often associated. It is important to distinguish septic arthritis of the pubic symphysis from its aseptic homologue, improperly called 'osteitis pubis' in English literature. This general term is mostly used to designate a mechanical pubic pain and has several aetiological meanings (joint stress, postoperative pain, rheumatic diseases). However, some authors consider the infection of the pubic symphysis as a variant of osteitis pubis, placing the two diseases in the continuum of the same entity. This confusion in pubic pathology related to its rarity and its atypical presentation, may in some cases lead to diagnostic and therapeutic delay. In this article, we would like to make practitioners aware of this uncommon and often ignored anatomical site, so that it can recover its place in the differential diagnosis of abdominal pain.

    Full Text Available Megan L Krause, Ashima Makol Division of Rheumatology, Department of Internal Medicine, Mayo Clinic, MN, USA Abstract: Rheumatoid arthritis, a chronic inflammatory autoimmune disease with significant physical disability, affects women three times more frequently than men, often in their childbearing years. Parenthood decisions can be challenging, often affected by perceptions of their disease state, health care needs, and complex pharmacological treatments. Many women struggle to find adequate information to guide them on pregnancy planning, lactation, and early parenting in relation to their chronic condition. The expanded availability and choice of pharmacotherapies have supported optimal disease control prior to conception and enhanced physical capabilities for women to successfully overcome the challenges of raising children but require a detailed understanding of their risks and safety in the setting of pregnancy and breastfeeding. This review outlines the various situational challenges faced by rheumatologists in providing care to men and women in the reproductive age group interested in starting a family. Up to date evidence-based solutions particularly focusing on the safe use of disease-modifying antirheumatic drugs and biologic response modifiers to assist rheumatologists in the care of pregnant and lactating women with RA are reviewed.

    Full Text Available Rheumatoid arthritis (RA is a chronic inflammatory disease associated with high cardiovascular morbidity and mortality. Epicardial adipose tissue (EAT thickness may act as a therapeutic target during treatments with drugs modulating the adipose tissue. We evaluate EAT thickness in RA patients treated with biological and nonbiological disease-modifying antirheumatic drugs (DMARDs. A cross-sectional study was conducted with a cohort of 34 female RA patients and 16 controls matched for age and body mass index (BMI. Plasma glucose, basal insulin, plasma lipids, and high-sensitivity C-reactive protein (hs-CRP were assessed. EAT thickness and left ventricular mass (LVM were measured by echocardiography. No significant differences in waist circumference (WC, blood pressure, fasting blood glucose, basal insulin, and lipid parameters were found between the groups. The control group showed lower concentrations (P=0.033 of hs-CRP and LVM (P=0.0001 than those of the two RA groups. Patients treated with TNF-α inhibitors showed significantly lower EAT thickness than those treated with nonbiological DMARDs (8.56 ± 1.90 mm versus 9.71 ± 1.45 mm; P=0.04. Women with no RA revealed reduced EAT thickness (5.39 ± 1.52 mm as compared to all RA patients (P=0.001. Results suggest that RA patients have greater EAT thickness than controls regardless of BMI and WC.

    The level and distribution of health risks in a society is substantially influenced by measures of various policies, programmes or projects. Risk assessment can evaluate the nature, likelihood and severity of an adverse effect. Health impact assessment (HIA) provides similar function when used as a...... risk appraisal phase to describe effects of various factors on different health outcomes. Consequently, HIA is typically led by a large, preferably intersectoral steering group with representatives of communities at risk. Risk assessment, in contrary, is mainly a licensed scientific process completed...... by licensed experts and lacks participatory approach. According to our findings, to be able to manage the analysis of the complex impact structure of various planned measures in HIA, the comprehensive assessment of health effects requires the analysis of the full impact scheme and must follow each...

    Full Text Available Eric G Boyce, Deepti Vyas, Edward L Rogan, Cynthia S Valle-Oseguera, Kate M O'Dell Department of Pharmacy Practice, Thomas J Long School of Pharmacy and Health Sciences, University of the Pacific, Stockton, CA, USAAbstract: Rheumatoid arthritis is a chronic, progressive autoimmune disease associated with inflammation and destruction of joints and systemic effects, which result in significant impact on patient's quality of life and function. Tofacitinib was approved for the treatment of rheumatoid arthritis in the USA in 2012 and subsequently in other countries, but not by the European Medicines Agency. The goal of this review was to evaluate the impact of tofacitinib on patient-reported and patient-specific outcomes from prior clinical studies, focusing on quality of life, functionality, pain, global disease assessment, major adverse consequences, and withdrawals. A total of 13 reports representing 11 clinical studies on tofacitinib in rheumatoid arthritis were identified through PubMed and reference lists in meta-analyses and other reviews. Data on improvements in patient-driven composite tools to measure disease activity in rheumatoid arthritis, such as the Health Assessment Questionnaire, served as a major outcome evaluated in this review and were extracted from each study. Additional data extracted from those clinical studies included patient assessment of pain (using a 0–100 mm visual analog scale, patient global assessment of disease (using a 0–100 mm visual analog scale, patient withdrawals, withdrawals due to adverse effects or lack of effect, and risk of serious adverse effects, serious infections, and deaths. Tofacitinib 5 mg bid appears to have a favorable impact on patient outcomes related to efficacy and safety when compared with baseline values and with comparator disease-modifying antirheumatic drugs and placebo. Improvements were seen in the composite and individual measures of disease activity. Serious adverse effects, other

    This review presents an overview of the range of imaging modalities used in the diagnostic evaluation of patients with psoriatic arthritis (PsA). Conventional radiography is used to detect structural changes of the joints and tendon attachments. These changes occur late in the course of PsA hence conventional radiography contributes little to the early detection of PsA; however, the detection of periosteal proliferations on radiographs allows a relatively specific diagnosis of PsA. Skeletal scintigraphy and computed tomography are rarely used in PsA. Arthrosonography (ultrasound of the joints) is gaining increasing importance in the early identification of inflammatory soft tissue signs of PsA in the peripheral joints. Sonography enables early detection of synovitis and tenosynovitis as well as superficial erosions and also inflammatory processes of the tendon attachments. Magnetic resonance imaging (MRI) is indispensable for identifying possible involvement of the axial skeleton. Moreover, it allows good visualization of periostitis and arthritis. High resolution microcomputed tomography is an interesting novel diagnostic tool which allows highly sensitive evaluation of the bone structure and can detect very tiny bone lesions where typical signs of PsA are omega-shaped erosions and small corona-like spikes. Another interesting new diagnostic technique is fluorescence optical imaging (FOI) with the Xiralite system which is highly sensitive for detecting inflammatory processes of the hands. PMID:24085530

    Increasing pressure on water supply worldwide, especially in arid areas, has resulted in groundwater overexploitation and contamination, and subsequent deterioration of the groundwater quality and threats to public health. Environmental risk assessment of regional groundwater is an important tool for groundwater protection. This study presents a new approach for assessing the environmental risk assessment of regional groundwater. It was carried out with a relative risk model (RRM) coupled with a series of indices, such as a groundwater vulnerability index, which includes receptor analysis, risk source analysis, risk exposure and hazard analysis, risk characterization, and management of groundwater. The risk map is a product of the probability of environmental contamination and impact. The reliability of the RRM was verified using Monte Carlo analysis. This approach was applied to the lower Liaohe River Plain (LLRP), northeastern China, which covers 23604 km2. A spatial analysis tool within GIS which was used to interpolate and manipulate the data to develop environmental risk maps of regional groundwater, divided the level of risk from high to low into five ranks (V, IV, III, II, I). The results indicate that areas of relative risk rank (RRR) V cover 2324 km2, covering 9.8% of the area; RRR IV covers 3986 km2, accounting for 16.9% of the area. It is a new and appropriate method for regional groundwater resource management and land use planning, and is a rapid and effective tool for improving strategic decision making to protect groundwater and reduce environmental risk.

  16. Sensation seeking related to varied definition of risk

    International Nuclear Information System (INIS)

    This pilot study is based on the assumption that the normal use of the word risk varies across subjects. It has been shown in previous risk perception studies that some people report their definition or normal use of the concept of risk as e.g. mainly probability, a combination of probability and consequences, mainly consequences, or due to the nature of the event (Drottz-Sjoeberg, 1991). Another field of research has developed measures for personality traits, i.e. facets of Sensation Seeking; Disinhibition, Thrill and Adventure Seeking, Experience Seeking, and Boredom Susceptibility (Zuckerman, 1994). The design of the present study involved three independent groups of first year psychology students (N=93). They were presented with one of three response formats regarding their normal use of the word risk, i.e. an open-ended format, separate ratings of four items suggesting a definition of risk on five-point scales, and one single five-point scale with the extremes labelled probability and consequences, and with their combination as the scale mid-point. The results showed, e.g. that the typical open-ended response to the personal definition of risk was 'danger', but among the responses were also 'chance', and 'outcome'. Another finding was that people who defined risk as 'outcome' and 'chance', using the open-ended format tended to score higher on the total Sensation Seeking Scale than those who defined risk as 'danger'. In addition, subjects who defined risk as the 'combination' of probability and consequences, using other response formats, also tended to score higher on the total Sensation Seeking Scale (SSS), especially as compared to those defining risk as the 'probability' of an event.

    Full Text Available Abstract Background Migraine, a common chronic-intermittent disorder of idiopathic origin characterized by severe debilitating headaches and autonomic nervous system dysfunction, and placental abruption, the premature separation of the placenta, share many common pathophysiological characteristics. Moreover, endothelial dysfunction, platelet activation, hypercoagulation, and inflammation are common to both disorders. We assessed risk of placental abruption in relation to maternal history of migraine before and during pregnancy in Peruvian women. Methods Cases were 375 women with pregnancies complicated by placental abruption, and controls were 368 women without an abruption. During in-person interviews conducted following delivery, women were asked if they had physician-diagnosed migraine, and they were asked questions that allowed headaches and migraine to be classified according to criteria established by the International Headache Society. Logistic regression procedures were used to calculate odds ratios (aOR and 95% confidence intervals (CI adjusted for confounders. Results Overall, a lifetime history of any headaches or migraine was associated with an increased odds of placental abruption (aOR = 1.60; 95% CI 1.16-2.20. A lifetime history of migraine was associated with a 2.14-fold increased odds of placental abruption (aOR = 2.14; 95% CI 1.22-3.75. The odds of placental abruption was 2.11 (95% CI 1.00-4.45 for migraineurs without aura; and 1.59 (95% 0.70-3.62 for migraineurs with aura. A lifetime history of tension-type headache was also increased with placental abruption (aOR = 1.61; 95% CI 1.01-2.57. Conclusions This study adds placental abruption to a growing list of pregnancy complications associated with maternal headache/migraine disorders. Nevertheless, prospective cohort studies are needed to more rigorously evaluate the extent to which migraines and/or its treatments are associated with the occurrence of placental abruption.

    Full Text Available Introduction Septic arthritis represents an intra-articular infection caused by pyogenic bacteria. During the earliest childhood it is considered to be a systemic septic condition and demands early diagnosis and prompt surgical treatment. Material and methods This is a retrospective analysis of patients with septic arthritis treated at the Department of Orthopedics of the Pediatric Surgery Clinic in Novi Sad, over a 10-year period. We are also presenting a case of a 12-day-old newborn baby, with clear radiological signs of osteoarthritis of the right knee. Results A retrospective study included the period 1991-2000, and showed that 15 patients, aged 10 days - 12 months were treated for osteoarthritis. The most common localization was the hip, in 60% of cases. In 11 patients the causative agent was Staphylococcus aureus while in the 4 remaining patients the bacteriologic finding was negative. One patient died of generalized sepsis. Discussion In neonates and infants septic arthritis is characterized by atypical clinical picture, often causing delayed diagnosis. In the initial phases of the disease ultrasonographic findings were of greater use compared to radiological imaging, due to relatively late appearance of radiological signs of disease. Conclusions Due to possible development of serious and irreversible damage, even lethal outcome, septic arthritis requires early diagnosis, prompt administration of antibiotics and early surgical treatment. It is a quite unique area in Pediatric Orthopedics where missed or delayed diagnosis may have serious consequences.

  4. Reactive arthritis or post-infective arthritis?

    Science.gov (United States)

    Keat, Andrew

    2002-09-01

    Infective mechanisms probably underlie a wide range of inflammatory arthropathies. There appears to be a spectrum of mechanisms ranging from the frankly septic, through low-grade infection with very small numbers of microorganisms in the joint to arthritides in which no hard evidence for an infective cause exists. In the midst of the spectrum lie 'post-infective' and 'reactive' arthritides, characterized clinically, genetically and by epidemiological links with infection. Identification of bacterial components within joint material from such patients suggested that the causes of the arthritis had been found. It is now clear that many bacteria are present in inflamed joints; establishing their significance will be of crucial importance, but not easy. PMID:12406424

  7. The relative benefits and risks of diagnostic procedures using radionuclides

    International Nuclear Information System (INIS)

    The risk of potential radiation damage from diagnostic procedures using radionuclides must be carefully balanced against the diagnostic and occasionally also therapeutic advantages offered by those methods. A global discussion of collective doses and collective risks appears rather useless for lack of differentiation. Instead, a variety of individual factors must be taken into account, which include the patient's age, the expected outcome of the disorder to be examined, the presence of pathological changes and possible therapeutic benefits from the diagnostic strategy adopted. The risk assessments in the study were made accordingly on the basis of statistical data and sample cases. They proved that in a large number of patients the benefits are by far greater than the associated risks. This statement must, however be modified by the fact that there are also cases where the diagnostic use of radiation should be approached with caution. (orig.)

  8. Relation between Childhood Obesity and Adult Cardiovascular Risk

    Directory of Open Access Journals (Sweden)

    Darren M. Allcock

    2009-01-01

    Full Text Available The incidence of overweight and obesity is rising at an alarming pace in the pediatric population, just as in the adult population. The adult comorbidities associated with this risk factor are well-recognized and are being further elucidated continually. Additionally, we are gradually developing a better understanding of the risks of overweight and obesity among children while they are still young. However, there is now a growing body of evidence showing that childhood obesity not only leads all too frequently to adult obesity, but is in itself a risk factor for cardiometabolic syndrome and resultant cardiovascular risk in adulthood. If current trends continue, the problem of pediatric overweight and obesity will become of unmanageable proportions once these individuals reach adulthood. Future research efforts toward understanding this complex problem will need to focus on those overweight and obese children who later went on to change their metabolic course and become normal-weight adults.

    Recent genome-wide association studies (GWAS) have identified eleven leukocyte telomere length (LTL)-related single nucleotide polymorphisms (SNPs). Since LTL has been associated with risk of many malignancies, LTL-related SNPs may contribute to cancer susceptibility. To test this hypothesis in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC), we genotyped these eleven LTL-related SNPs in a case-control set including 1186 HBV-related HCC cases, 508 chronic HBV carriers and 1308 healthy controls at the discovery stage. The associations of HCC risk with these SNPs were further confirmed in an independent case-control set. We found that 1p34.2 rs621559 and 14q21 rs398652 were significantly associated with HBV-related HCC risk (both PHCC cases and 1954 controls), we observed a decreased HCC risk, 0.72-times, associated with the 1p34.2 rs621559 AA genotype compared to the GG genotype (P = 1.6×10(-6)). Additionally, there was an increased HCC risk, 1.27-fold, associated with the rs398652 GG genotype (P = 3.3×10(-6)). A statistical joint effect between the rs621559 GG and rs398652 GG genotypes may exist in elevating risk of HBV-related HCC. We show, for the first time, that rs398652 and rs621559 might be marker genetic variants for risk of HBV-related HCC in the Chinese population. PMID:25365256

    Hertzberger-ten Cate, R; Fiselier, T

    1991-10-01

    On basis of clinical and immunogenetic factors most children with pauciarticular juvenile chronic arthritis can be included in one of the subtypes: type 1 and type 2 pauciarticular JCA. Type 1 occurs in young children, mainly girls, with involvement of knees, ankles or elbows. In the majority of children antinuclear antibodies can be detected. The presence of these autoantibodies is associated with chronic anterior uveitis. Type 2 or the juvenile spondylarthropathies include morbus Bechterew, the reactive arthritides and arthritis associated with psoriasis and inflammatory bowel diseases. Large joints of the lower extremities are involved, back pain is unusual at onset, but enthesitis is frequently present. There is a strong association with HLA-B27. Treatment of both subsets consists of non-steroidal anti-inflammatory drugs, application of intra-articular steroids, physio- and hydrotherapy and splinting. In children with a polyarticular course of type 1, or a prolonged course of type 2 disease modifying drugs are often needed. PMID:1957301

    2004-01-01

    In this study, we describe the relationship between self-esteem and HIV-related risk behaviors, and explore what factors predict self-esteem levels of "at risk" women. Interviews were conducted with 250 (predominantly African American) women living in the Atlanta, Georgia metropolitan area between August 1997 and August 2000. A community identification process was used to identify potential study participants, with further expansion of the sample via targeted and theoretical sampling and ethnographic mapping procedures. Self-esteem was related to the number of times having oral sex, the number of times having sex with paying partners, the frequency of sexual risk-taking (all during the 90 days prior to interview), the number of different HIV risk behaviors practiced during the previous year, and condom use attitudes and self-efficacy. Greater involvement HIV risk behaviors was associated with lower self-esteem. Multivariate analyses revealed five significant predictors of women's self-esteem levels: race, religiosity, childhood experiences with emotional neglect, the number of money-related problems experienced, and the number of drug-related problems experienced. The findings indicate that self-esteem is highly relevant to "at risk" women's HIV risk behavior practices, and this has important implications for HIV intervention programs. PMID:15911511

    The aim of this pilot study was to evaluate the response to 16 and 52 weeks of treatment with adalimumab and etanercept and its effect on disease activity and quality of life in patients with rheumatoid arthritis (RA). Patients were selected from 2155 medical cards of patients of Connective Tissue Health Centre (Poznań, Poland) who were refractory to conventional treatment with disease modifying anti-rheumatic drugs. To assess the disease activity, Disease Activity Score (DAS28) was used and the measurement of quality of life was evaluated with the Polish version of the WHOQoL-Bref questionnaire. To assess the disability, we have used Health Assessment Questionnaire Disability Index (HAQ-DI) and to assess the patients' pain caused by RA, Visual Analogue Scale (VAS) was used. The results of the study show a significant decrease in inflammatory activity of the disease and, consequently, an improvement in quality of life after anti-TNF α treatment. Results obtained with TNF-blockers after 52 weeks of treatment in RA objectively show the efficacy of these drugs and also the patients' perception of the effect on their quality of life. Study results also indicate changes in disability caused by RA and patients' pain due to disease between 16 and 52 weeks of treatment. PMID:27180448

    2016-06-01

    Psoriasis and psoriatic arthritis (PsA) are chronic immune-mediated diseases that primarily affect the skin and joints, respectively; these diseases are also associated with high rates of cardiovascular and other comorbidities. Despite over 40 genes proven to be related to the disease, the exact causes of psoriasis and PsA are still to be determined. Recent insights into the underlying pathophysiology of these diseases have revealed novel therapeutic targets. Effective management requires timely diagnosis and initiation of treatment. Yet, both psoriasis and PsA remain underrecognized and undertreated in current clinical practice. Recognizing the true physical, social, and emotional burden of psoriasis and PsA, as well as their associated comorbidities, is the first step to improving the prognosis for affected patients.

    Psoriasis vulgaris (PsV) and psoriatic arthritis (PsA) are inter-related disorders, with PsA representing a disease within a disease. From an epidemiological perspective, the genetic contributions of PsV and PsA are now well documented. HLA-C is firmly established as a PsV/PsA gene, with HLA-Cw*0602 as a major risk allele. Fine mapping studies within the MHC region in PsV and PsA have identified novel loci that are independent of the HLA-Cw6 allele. Recent genome-wide association scans have l...

    This paper presents a summary of the evidence review group (ERG) report into the use of golimumab for the treatment of psoriatic arthritis (PsA). The main clinical effectiveness data were derived from a single phase III randomised controlled trial (RCT: GO-REVEAL) that compared golimumab with placebo for treating patients with active and progressive PsA who were symptomatic despite the use of previous disease-modifying antirheumatic drugs or non-steroidal anti-inflammatory drugs. The 14-week data showed that, compared with placebo, golimumab 50 mg significantly improved joint disease response as measured by American College of Rheumatology (ACR) 20 [relative risk (RR) 5.73, 95% confidence interval (CI) 3.24 to 10.56] and Psoriatic Arthritis Response Criteria (PsARC) (RR 3.45, 95% CI 2.49 to 4.87), and skin disease response as measured by the Psoriasis Area and Severity Index (PASI) 75 (RR 15.95, 95% CI 4.62 to 59.11). The 24-week absolute data showed that these treatment benefits were maintained. There was a significant improvement in patients' functional status as measured by the Health Assessment Questionnaire (HAQ) change from baseline at 24 weeks (-0.33, p patient crossover at week 16. The manufacturer conducted a mixed treatment comparison (MTC) analysis. The ERG considered the assumption of exchangeability between the trials for the purpose of the MTC analysis to be acceptable, and the statistical approach in the MTC analysis to be reliable. Regarding the safety evaluation of golimumab, the manufacturer failed to provide longer-term data or to consider adverse event data of golimumab from controlled studies in other conditions, such as rheumatoid arthritis and ankylosing spondylitis. Although the adverse effect profile of golimumab appears similar to other anti-tumour necrosis factor (TNF) agents, the longer-term safety profile of golimumab remains uncertain. The manufacturer's submission presented a decision model to compare etanercept, infliximab, golimumab

    Full Text Available Background: Growth of scientific evidence suggests an exquisite association between oral infection and systemic diseases. Though etiologies of periodontitis and rheumatoid arthritis (RA are separate, their underlying pathological processes are sufficient to warrant consideration of hypothesis that individuals at risk of developing RA may also be at the risk of developing periodontitis and vice versa. Materials and Methods: To test their relationship, a study was carried out on 80 individuals. Part A: Forty subjects having rheumatoid arthritis (RA group were compared to 40 controls without arthritis (NRA group. Their periodontal indices rheumatoid arthritis clinical laboratory parameters were also correlated with periodontitis in group. Part B: Omplete periodontal treatment was done for 10 patients of group suffering from periodontitis. All parameters of periodontal indices were measured pre-operatively and weeks after completion of periodontal treatment. Results: (1 There was high prevalence of mild (12.5% to moderate (75% periodontitis in group. (2 Extent severity of periodontal disease rheumatoid arthritis were positively correlated. (3 Statistically significant differences were present in periodontal parameters of RA group compared to NRA group. (4 There was statistically, significant reduction in parameters postoperatively with concomitant decrease in periodontal parameters in RA group. Conclusion: Thus, an association exists between periodontal disease with an underlying dysregulation of the molecular pathways in the inflammatory response. Also, there are significant management implications in the future as new host modifying medications are developed.

  10. Radiographic abnormalities of the wrist in adult-onset still disease: Comparison with juvenile chronic arthritis and rheumatoid arthritis

    International Nuclear Information System (INIS)

    Pericapitate involvement of the wrist has been described as characteristic of adult-onset Still disease, a relatively rare disorder that is often diagnosed by exclusion after extensive and frequently invasive tests. To evaluate the diagnostic value of carpal radiography in cases of adult-onset Still disease, a retrospective blinded analysis of 48 patients, 16 each with adult-onset Still disease, juvenile chronic arthritis, and rheumatoid arthritis, was performed. Pericapitate articular alterations without radiocarpal involvement were found to be frequent in the setting of adult-onset Still disease but distinctly unusual among patients with rheumatoid arthritis. In juvenile chronic arthritis, severe pericapitate involvement was frequent, but generally occurred in conjunction with radiocarpal joint abnormalities

    Full Text Available The effects of an intervention is best measured in a randomized controlled trial (RCT and can be expressed in various ways using the measures such as risk difference, number needed to treat (NNT, relative risk or odds ratio. Risk difference (RD is the difference in risk of the outcome event between control and experimental group. Control group is not exposed to the intervention, whereas experimental group is the one that is exposed to intervention. The risk of outcome event in the control group is also called baseline risk. The NNT is the inverse of the risk difference and indicates the number of patients required to be treated to avoid one additional outcome event. Risk difference and NNT are absolute measures of effect. Relative risk (RR is a relative measure and is the ratio of the risk in the exposed group to that in the unexposed group. Relative risk reduction (RRR is one minus RR and indicates the fraction (or percent of baseline risk that reduces with exposure to the intervention. Odds ratio (OR is ratio of odds of having the event in the exposed group to that in the unexposed group. These measures are suitable for different purposes and appeal to different constituencies. Odds ratio is the only measure suitable for use in logistic regression and case control studies.

    2015-09-01

    Rheumatoid arthritis (RA) is a chronic debilitating autoimmune disorder characterized by synovitis that leads to cartilage and bone erosion by invading fibrovascular tissue. Mouse models of RA recapitulate many features of the human disease. Despite the availability of medicines that are highly effective in many patient populations, autoimmune diseases (including RA) remain an area of active biomedical research, and consequently mouse models of RA are still extensively used for mechanistic studies and validation of therapeutic targets. This review aims to integrate morphologic features with model biology and cover the key characteristics of the most commonly used induced and spontaneous mouse models of RA. Induced models emphasized in this review include collagen-induced arthritis and antibody-induced arthritis. Collagen-induced arthritis is an example of an active immunization strategy, whereas antibody- induced arthritis models, such as collagen antibody-induced arthritis and K/BxN antibody transfer arthritis, represent examples of passive immunization strategies. The coverage of spontaneous models in this review is focused on the TNFΔ (ARE) mouse, in which arthritis results from overexpression of TNF-α, a master proinflammatory cytokine that drives disease in many patients.

    In the first part of this work, the progress of Italian National Rules about dams design, construction and operation are presented to highlight the strong connection existing between the promulgation of new decrees, as a consequence of a dam accidents, and the necessity to prevent further loss of lives and goods downstream. Following the Gleno Dam failure (1923), a special Ministerial Committee wrote out the first Regulations and made the proposal to establish, within the High Council of Public Works, a special department that become soon the "Dam Service", with the tasks of control and supervision about construction and operation phases of the dams and their reservoirs. A different definition of tasks and the structure of Dam Service were provided in accordance with law n° 183/1989, which transferred all the technical services to the Office of the Prime Minister; the aim was to join the Dam Office with the Department for National Technical Services, with the objective of increasing the knowledge of the territory and promoting the study on flood propagation downstream in case of operations on bottom outlet or hypothetical dam-break. In fact, population living downstream is not ready to accept any amount of risk because has not a good knowledge of the efforts of experts involved in dam safety, both from the operators and from the safety Authority. So it's important to optimize all the activities usually performed in a dam safety program and improve the emergency planning as a response to people's primary needs and feeling about safety from Civil Protection Authority.

    Immunodiagnostics play an important role in the differential diagnostics of arthritis but the test results must be interpreted with respect to the clinical context. The detection of antibodies against citrullinated proteins has significantly improved the immunodiagnostics of arthritis, whereas the importance of testing for rheumatoid factor has decreased due to the low specificity. Antibodies against carbamylated or oxidized proteins will expand the immunodiagnostics of arthritis (especially rheumatoid arthritis) in the future. In contrast, the determination of cytokine concentrations in plasma or synovial fluid plays a subordinate role in the differential diagnostics of arthritis. Indirect immunofluorescence continues to be the gold standard in the detection of antinuclear antibodies (ANA) and in the case of positive results further testing for antigen specificity should be carried out. The presence of ANA is not necessarily associated with autoimmune diseases. An example of a non-pathogenic ANA is anti-DFS70 antibodies. PMID:27142378

    Full Text Available There is no doubt that inflammatory arthritis/enthesitis and psoriasis coexist more frequently than would be expected by chance: for instance, in a study of 1285 patients with psoriasis seen in an hospital, 483 (38% were suffering from arthritis/ enthesitis, including 40 patients classified as Rheumatoid Arthritis (RA (3%, 177 (14% as undifferentiated arthritis (UA, and 266 (21% as Psoriatic Arthritis (PsA (1. Although lower percentages have been noticed in the general population with psoriasis (6% of PsA in an extensive study of 1844 patients with psoriasis (2, they were superior to 5% (i.e. at least 5 times greater than the figures found for patients without psoriasis (3-7.

    Full Text Available We evaluated the association between anti-cyclic citrullinated peptide antibodies (anti-CCP and anti-mutated citrullinated vimentin antibodies (anti-MCV with the presence of extra-articular (ExRA manifestations in 225 patients with rheumatoid arthritis (RA. Ninety-five patients had ExRA and 130 had no ExRA. There was no association of anti-CCP and anti-MCV levels with the presence of ExRA as total group (P=0.40 and P=0.91, resp.. Making an analysis of individual manifestations, rheumatoid nodules were associated with positivity for rheumatoid factor (RF; (P=0.01, anti-CCP (P=0.048, and anti-MCV (P=0.02. Instead, RF, anti-CCP, or anti-MCV were not associated with SS, chronic anemia, or peripheral neuropathy. Levels of anti-CCP correlated with the score of the Health Assessment Questionnaire-Disability Index (HAQ-Di (r=0.154, P=0.03, erythrocyte sedimentation rate (ESR; (r=0.155, P=0.03, and RF (P=0.254, P<0.001, whereas anti-MCV titres only correlated with RF (r=0.169, P=0.02. On adjusted analysis, ExRA was associated with longer age (P=0.015, longer disease duration (P=0.007, higher DAS-28 score (P=0.002, and higher HAQ-DI score (P=0.007, but serum levels of anti-CCP and anti-MCV were not associated. These findings show the need to strengthen the evaluation of the pathogenic mechanisms implied in each specific ExRA manifestation.

    The autoimmune diseases are among the 10 leading causes of death for women and the number two cause of chronic illness in America as well as a predisposing factor for cardiovascular diseases and cancer. Patients of some autoimmune diseases have shown a shorter life span and are a model of accelerated immunosenescence. Conversely, centenarians are used as a model of successful aging and have shown several immune parameters that are better preserved and lower levels of autoantibodies. The study reported here focused on clarifying the connection between longevity and some autoimmune and allergic diseases in 29 developed Organisation for Economic Co-operation and Development (OECD) countries, because multidisciplinary analyses of the accelerated or delayed aging data could show a distinct relationship pattern, help to identify common factors, and determine new important factors that contribute to longevity and healthy aging. The relationships between the mortality rates data of multiple sclerosis (MS), rheumatoid arthritis (RA), asthma, the incidence of type 1 diabetes (T1D) from one side and centenarian rates (two sets) as well as life expectancy data from the other side were assessed using regression models and Pearson correlation coefficients. The data obtained correspond to an inverse linear correlation with different degrees of linearity. This is the first observation of a clear tendency of diminishing centenarian rates or life expectancy in countries having higher death rates of asthma, MS, and RA and a higher incidence of T1D in children. The conclusion is that most probably there are common mechanistic pathways and factors affecting the above diseases and at the same time but in the opposite direction the processes of longevity. Further study, comparing genetic data, mechanistic pathways, and other factors connected to autoimmune diseases with those of longevity could clarify the processes involved, so as to promote longevity and limit the expansion of those

  11. Leukocyte telomere length-related rs621559 and rs398652 genetic variants influence risk of HBV-related hepatocellular carcinoma.

    Full Text Available Recent genome-wide association studies (GWAS have identified eleven leukocyte telomere length (LTL-related single nucleotide polymorphisms (SNPs. Since LTL has been associated with risk of many malignancies, LTL-related SNPs may contribute to cancer susceptibility. To test this hypothesis in hepatitis B virus (HBV-related hepatocellular carcinoma (HCC, we genotyped these eleven LTL-related SNPs in a case-control set including 1186 HBV-related HCC cases, 508 chronic HBV carriers and 1308 healthy controls at the discovery stage. The associations of HCC risk with these SNPs were further confirmed in an independent case-control set. We found that 1p34.2 rs621559 and 14q21 rs398652 were significantly associated with HBV-related HCC risk (both P<0.005 after Bonferroni corrections. There was no significant difference of either rs621559 or rs398652 genotypes between chronic HBV carriers and healthy controls, demonstrating that the association was not due to predisposition to HBV infection. In the pooled analyses (1806 HBV-related HCC cases and 1954 controls, we observed a decreased HCC risk, 0.72-times, associated with the 1p34.2 rs621559 AA genotype compared to the GG genotype (P = 1.6×10(-6. Additionally, there was an increased HCC risk, 1.27-fold, associated with the rs398652 GG genotype (P = 3.3×10(-6. A statistical joint effect between the rs621559 GG and rs398652 GG genotypes may exist in elevating risk of HBV-related HCC. We show, for the first time, that rs398652 and rs621559 might be marker genetic variants for risk of HBV-related HCC in the Chinese population.

    Multiple chronic disease risks have been identified in Italian furnace workers. A range of potential toxins have been identified in foundry dust. We suggest that the heavy metal cadmium (Cd) plays an important role in the development of chronic diseases, notably rheumatoid arthrits, and propose that research into the mechanism of action be undertaken to discover the aetiology of this link.

    Full Text Available INTRODUCTION: Amphotericin B (AmphoB is the drug of choice for treatment of severe fungal illnesses; however, it is very nephrotoxic. Modified (less toxic amphotericins are very expensive. In low-risk patients, saline loading would be enough to prevent significant loss of renal function. MATERIAL AND METHODS: Patients with normal renal function and within the first 24 hours of treatment with AmphoB were prospectively enrolled in the study. Patients in intensive care units or who were using vasoactive drugs were excluded. Saline loads were infused before and after the AmphoB treatment. Blood and urine analyses were made at the beginning and at the end of the treatment. Serum creatinine was repeated 30 days after the end of the AmphoB treatment. RESULTS: The mean increase in serum creatinine in the 48 patients was 0.3 (0.18-0.41 mg/dL, due to a mean decrease of 25 (12.8-36.9 mL/min of creatinine clearance (CrCl. Acute renal failure, defined as an increase of more than 50% of the baseline creatinine, occurred in 15 patients (31%. Patients that were on antibiotics, in post-chemotherapy status or those submitted to bone marrow transplantation had the highest risk. Mean serum creatinine and the CrCl levels were no different from baseline values after 30 days. CONCLUSION: In low-risk patients, the use of AmphoB with prophylactic sodium chloride loading was associated with a small and reversible decrease in renal function. Due to its high cost the use of more expensive therapies for this type of patient does not seem to be justified.

    Full Text Available OBJECTIVES: The aim of this study was to report the type and frequency of ocular manifestations in Brazilian psoriatic arthritis patients. METHODS: We conducted a cross-sectional study in a Brazilian tertiary hospital. The test group included 40 patients who had psoriatic arthritis according to the Classification Criteria for Psoriatic Arthritis. A control group of 40 individuals was matched for age and gender. All of the patients underwent ophthalmic evaluation, which included best-corrected visual acuity, slit lamp and fundus examinations, and dry eye diagnostic tests (Schirmer I, tear breakup time and rose bengal. Demographic parameters were also evaluated. RESULTS: The mean age of the patients was 53.9±13.1 years; the mean disease duration was 8±10.5 years. Most of the patients were women (60%, and the majority had polyarticular disease (57.5%. Several ocular abnormalities were found, including punctate keratitis, pinguecula, blepharitis, pterygium, cataract, glaucoma, uveitis, and retinal microvascular abnormalities. There were no significant differences in the rates of these abnormalities compared with the control group, however. The Keratoconjunctivitis sicca and dry eye diagnostic tests were more often positive in the patients with psoriatic arthritis than in the control group. CONCLUSIONS: In this study, keratoconjunctivitis sicca was the most common ocular finding related to psoriatic arthritis. Therefore, we recommend early ophthalmologic evaluations for all psoriatic arthritis patients who complain of eye symptoms.
