Microcrystals As Damps And Their Role In Joint Inflammation

The concept of danger signals as important triggers of inflammation and immune activation has passed from fanciful hypothesis to a widely accepted biological process with receptors, signalling cascades and mediators. Products of cell death or cell stress are prime examples of DAMPs. They interact with receptors on the cell surface such as TLRs as well as cytoplasmic proteins such as the NLRs to modulate cellular metabolism and activation. Recently, the identification of the inflammasomes and their role in processing IL-1b and IL18 provided further insights into how DAMPs provoke inflammation. A class of substances that are potent activators of the inflammasome is microcrystals. All three microcrystals associated with joint disease in man : urate, CPP and hydroxyapatite require the NLRP3 inflammasome to process and release IL-1b from leucocytes. This mechanism most probably explain the inflammatory phase of acute crystal arthritis. However, microcrystals can also induce apoptosis, cell death as well as cell activation, depending on the cell type they are in contact with. These different cellular effects could well explain the role crystals can play in degenerative joint diseases, where inflammation is not as prominent. Our understanding of the intracellular pathways linking microcrystals to inflammation and cell activation is currently still very sketchy, and we hope that the detailed analysis of these pathways may lead to better comprehension and treatment of microcrystal induced joint diseases.Disclosures : The author has declared no conflicts of interest.

Recurrent dominant mutations affecting two adjacent residues in the motor domain of the monomeric kinesin KIF22 result in skeletal dysplasia and joint laxity.

Spondyloepimetaphyseal dysplasia with joint laxity, leptodactylic type (lepto-SEMDJL, aka SEMDJL, Hall type), is an autosomal dominant skeletal disorder that, in spite of being relatively common among skeletal dysplasias, has eluded molecular elucidation so far. We used whole-exome sequencing of five unrelated individuals with lepto-SEMDJL to identify mutations in KIF22 as the cause of this skeletal condition. Missense mutations affecting one of two adjacent amino acids in the motor domain of KIF22 were present in 20 familial cases from eight families and in 12 other sporadic cases. The skeletal and connective tissue phenotype produced by these specific mutations point to functions of KIF22 beyond those previously ascribed functions involving chromosome segregation. Although we have found Kif22 to be strongly upregulated at the growth plate, the precise pathogenetic mechanisms remain to be elucidated.

A new approach to accurate measurement of uniaxial joint angles based on a combination of accelerometers and gyroscopes.

A new method of measuring joint angle using a combination of accelerometers and gyroscopes is presented. The method proposes a minimal sensor configuration with one sensor module mounted on each segment. The model is based on estimating the acceleration of the joint center of rotation by placing a pair of virtual sensors on the adjacent segments at the center of rotation. In the proposed technique, joint angles are found without the need for integration, so absolute angles can be obtained which are free from any source of drift. The model considers anatomical aspects and is personalized for each subject prior to each measurement. The method was validated by measuring knee flexion-extension angles of eight subjects, walking at three different speeds, and comparing the results with a reference motion measurement system. The results are very close to those of the reference system presenting very small errors (rms = 1.3, mean = 0.2, SD = 1.1 deg) and excellent correlation coefficients (0.997). The algorithm is able to provide joint angles in real-time, and ready for use in gait analysis. Technically, the system is portable, easily mountable, and can be used for long term monitoring without hindrance to natural activities.

Clinical and ultrasonographic predictors of joint replacement for knee osteoarthritis: results from a large, 3-year, prospective EULAR study.

OBJECTIVES: To determine clinical and ultrasonographic predictors of joint replacement surgery across Europe in primary osteoarthritis (OA) of the knee. METHODS: This was a 3-year prospective study of a painful OA knee cohort (from a EULAR-sponsored, multicentre study). All subjects had clinical evaluation, radiographs and ultrasonography (US) at study entry. The rate of knee replacement surgery over the 3-year follow-up period was determined using Kaplan-Meier survival data analyses. Predictive factors for joint replacement were identified by univariate log-rank test then multivariate analysis using a Cox proportional-hazards regression model. Potential baseline predictors included demographic, clinical, radiographic and US features. RESULTS: Of the 600 original patients, 531 (88.5%), mean age 67+/-10 years, mean disease duration 6.1+/-6.9 years, had follow-up data and were analysed. During follow-up (median 3 years; range 0-4 years), knee replacement was done or required for 94 patients (estimated event rate of 17.7%). In the multivariate analysis, predictors of joint replacement were as follows: Kellgren and Lawrence radiographic grade (grade > or =III vs <III, hazards ratio (HR) = 4.08 (95% CI 2.34 to 7.12), p<0.0001); ultrasonographic knee effusion (> or =4 mm vs <4 mm) (HR = 2.63 (95% CI 1.70 to 4.06), p<0.0001); knee pain intensity on a 0-100 mm visual analogue scale (> or =60 vs <60) (HR = 1.81 (95% CI 1.15 to 2.83), p=0.01) and disease duration (> or =5 years vs <5 years) (HR=1.63 (95% CI 1.08 to 2.47), p=0.02). Clinically detected effusion and US synovitis were not associated with joint replacement in the univariate analysis. CONCLUSION: Longitudinal evaluation of this OA cohort demonstrated significant progression to joint replacement. In addition to severity of radiographic damage and pain, US-detected effusion was a predictor of subsequent joint replacement.

Globalization and wage inequality in South and East Asia, and Latin America: A gender approach

In this paper we analyse the reasons behind the evolution of the gender gap and wage inequality in South and East Asian and Latin American countries. Health human capital improvements, the exposure to free market openness and equal treatment enforcement laws seem to be the main exogenous variables affecting women s economic condition. During the second globalization era (in the years 1975-2000) different combinations of these variables in South East Asian and Latin American countries have had as a result the diminution of the gender gap. The main exception to this rule according to our data is China where economic reforms have been simultaneous to the increase of gender differences and inequality between men and women.This result has further normative consequences for the measure of economic inequality. Theimprovement of women s condition has as a result the diminution of the dispersion of wages.Therefore in most of the countries analysed the consequence of the diminution of the gender gapduring the second global era is the decrease of wage inequality both measured with Gini and Theil indexes.

Nationalisme économique et réalisme mercantile : la politique énergétique russe sous Poutine (2000-2008)

Mon travail met en évidence la restructuration de l'industrie énergétique russe sous les deux mandats Poutine (2000-2008) via le rôle prédominant de l'État dans une perspective historique. Une nouvelle élite politique russe (les Silovikis) issue des structures de force de l'Etat favorise le nationalisme économique axé sur le rétablissement de l'autorité du gouvernement central au sein de l'industrie énergétique nationale au détriment des pouvoirs régionaux, des sociétés privées étrangères et des oligarques indépendants. Dans cette perspective, on peut citer "l'affaire Youkos" en 2003 caractérisée par l'arrestation de l'oligarque Mikhaïl Khodorkhovsky; les tentatives silovikiennes de reprendre l'ascendant sur les compagnies pétrolières régionales Tatneft et Bachneft gérées par les gouvernements tatar et bachkir, la pression fiscale envers les majors pétrolières étrangères à l'instar du conflit russo- britannique relatif à la joint-venture TNK-BP. Quant à la politique énergétique étrangère russe, elle est inspirée par line vision réaliste mercantile; le gouvernement silovikien vise à défendre l'intérêt national, le prestige et la puissance de la Russie via ses "champions" énergétiques Rosneft et Gazprom utilisés comme levier politique, notamment à l'égard des pays de la CEI considéré par Moscou comme sa sphère d'influence historique. Dans cette perspective, nous pouvons mentionner l'interruption des approvisionnements pétroliers et gaziers russes à l'Ukraine, aux Etats baltes ou encore à la Géorgie; la concurrence entre les majors russes et étrangères en Asie centrale / Caucase pour les champs pétrolifères et les tracés de pipelines (nouveau «Grand Jeu»); la diversification des marchés russes à l'exportation à travers la promotion de nouveaux pipelines partant des champs pétrolifères sibériens vers la Chine et l'océan Pacifique.¦My work highlights the restructuration of the Russian energy industry under the 2 Putin madates (2000-2008) by the predominant role of the state in a historical perspective. A new Russian politic elite (Siloviki) from state structure forces promotes the economic nationalism focused on the reestablishment of the central governmental authority in the national energy industry against regional powers, private foreign companies and independent oligarchs. In this perspective, we can mention the "Yukos Affair" in 2003 with the arrest of the oligarch Mikhail Khodorkhovsky; the silovikian attempts to take over the regional oil companies Tatneft and Bachneft handled by the Tatar and Bashkir governments; the fiscal silovikian pressure against foreign companies such as the Russo-Britannic joint- venture TNK-BP. As for the Russian energy Foreign policy, it is inspired by a mercantile realism vision; the silovikian government aims to defend the national interest, the prestige and the power of Russia through its energy companies Rosneft and Gazprom as a political leverage especially toward the CEI Countries considered by Moscow as it historical sphere of influence. In this perspective, we can mention the interruption of Russian oil&gas supply toward Ukraine, Baltic states or Georgia; the competition between Russian and foreign companies in Central Asia/Caucasus for oil and gas fields and pipeline routes (new "Great Game"); the diversification of Russian export markets through the promotion ο new pipelines from Siberian oil&gas fields to China and the Pacific Ocean.

Building an honest microfinance organization: Embezzlement and the optimality of rigid repayment schedules and joint liability

We consider the agency problem of a staff member managing microfinancing programs, who can abuse his discretion to embezzle borrowers' repayments. The fact that most borrowers of microfinancing programs are illiterate and live in rural areas where transportation costs are very high make staff's embezzlement particularly relevant as is documented by Mknelly and Kevane (2002). We study the trade-off between the optimal rigid lending contract and the optimal discretionary one and find that a rigid contract is optimal when the audit cost is larger than gains from insurance. Our analysis explains rigid repayment schedules used by the Grameen bank as an optimal response to the bank staff's agency problem. Joint liability reduces borrowers' burden of respecting the rigid repayment schedules by providing them with partial insurance. However, the same insurance can be provided byborrowers themselves under individual liability through a side-contract.

Structural joint inversion of time-lapse crosshole ERT and GPR traveltime data

Time-lapse geophysical monitoring and inversion are valuable tools in hydrogeology for monitoring changes in the subsurface due to natural and forced (tracer) dynamics. However, the resulting models may suffer from insufficient resolution, which leads to underestimated variability and poor mass recovery. Structural joint inversion using cross-gradient constraints can provide higher-resolution models compared with individual inversions and we present the first application to time-lapse data. The results from a synthetic and field vadose zone water tracer injection experiment show that joint 3-D time-lapse inversion of crosshole electrical resistance tomography (ERT) and ground penetrating radar (GPR) traveltime data significantly improve the imaged characteristics of the point injected plume, such as lateral spreading and center of mass, as well as the overall consistency between models. The joint inversion method appears to work well for cases when one hydrological state variable (in this case moisture content) controls the time-lapse response of both geophysical methods.

From correspondence analysis to multiple and joint correspondence analysis

The generalization of simple (two-variable) correspondence analysis to more than two categorical variables, commonly referred to as multiple correspondence analysis, is neither obvious nor well-defined. We present two alternative ways of generalizing correspondence analysis, one based on the quantification of the variables and intercorrelation relationships, and the other based on the geometric ideas of simple correspondence analysis. We propose a version of multiple correspondence analysis, with adjusted principal inertias, as the method of choice for the geometric definition, since it contains simple correspondence analysis as an exact special case, which is not the situation of the standard generalizations. We also clarify the issue of supplementary point representation and the properties of joint correspondence analysis, a method that visualizes all two-way relationships between the variables. The methodology is illustrated using data on attitudes to science from the International Social Survey Program on Environment in 1993.

Characteristics and outcome of knee prosthetic joint infections (PJI): A 10-year cohort study (2000-2009)

Background: Prosthetic joint infections (PJI) lead to significant long-term morbidity with high cost of healthcare. We evaluated characteristics of infections and the infection and functional outcome of knee PJI over a 10-year period. Methods: All patients hospitalized at our institution from 1/2000 through 12/2009 with knee PJI (defined as growth of the same microorganism in ≥2 tissue or synovial fluid cultures, visible purulence, sinus tract or acute inflammation on tissue histopathology) were included. Patients, their relatives and/or treating physicians were contacted to determine the outcome. Results: During the study period, 61 patients with knee PJI were identified. The median age at the time of diagnosis of infection was 73 y (range, 53-94 y); 52% were men. Median hospital stay was 37 d (range, 1-145 d). Most reasons for primary arthroplasty was osteoarthritis (n = 48), trauma (n = 9) and rheumatoid arthritis (n = 4). 23 primary surgeries (40%) were performed at CHUV, 34 (60%) elsewhere. After surgery, 8 PJI were early (<3 months), 16 delayed (3-24 months) and 33 late (>24 months). PJI were treated with (i) open or arthroscopic debridement with prosthesis retention in 26 (46%), (ii) one-stage exchange in 1, (iii) two-stage exchange in 22 (39%) and (iv) prosthesis removal in 8 (14%). Isolated pathogens were S. aureus (13), coagulase-negative staphylococci (10), streptococci (5), enterococci (3), gram-negative rods (3) and anaerobes (3). Patients were followed for a median of 3.1 years, 2 patients died (unrelated to PJI). The outcome of infection was favorable in 50 patients (88%), whereas the functional outcome was favorable in 33 patients (58%). Conclusions: With the current treatment concept, the high cure rate of infection (88%) is associated with a less favorable functional outcome o 58%. Earlier surgical intervention and more rapid and improved diagnosis of infection may improve the functional outcome of PJI.
