L'inno avestico agli Aməsha Spəṇtas (Yasht 2). Testo critico e traduzione con commentario storico religioso

L'inno dedicato ai sette Amesha Spəṇta è parte della produzione avestica recenziore, e si compone in gran parte di porzioni testuali riprese da altri testi avestici a loro volta di formazione tardiva. Lo Yašt si divide in tre parti principali: le stanze 0-10; 11-14; e infine la stanza 15 che comprende la formula di chiusura tipica degli inni avestici. La prima sezione (2.0-10) è composta dalla formula di apertura, incompleta rispetto a quelle dei restanti inni, seguita dai primi sette capitoli di entrambi i Sīh-rōzag compresi i Gāh. Le stanze centrali (11-14) si caratterizzano per l'assenza di passi gemelli, un elevato numero di hapax e di arcaismi formali e inoltre, una grande variabilità nella tradizione manoscritta. Si tratta di una formula magica per esorcizzare/allontanare demoni e stregoni, che doveva essere recitata per sette volte. Tale formula probabilmente rappresentava in origine un testo autonomo che veniva recitato assieme ad altri testi avestici. La versione a noi pervenuta comprende la recitazione di parte di entrambi i Sīh-rōzag, ma è molto probabile che tale arrangement sia soltanto una sequenza recitativa che doveva coesistere assieme ad altre. Attualmente la formula magica viene recitata principalmente assieme allo Yasna Haptaŋhāiti, senza le restanti stanze dell'inno nella sua versione geldneriana. Il testo sembra nascere come formula magica la quale venne recitata assieme a diversi testi avestici come per esempio parti dello Sīh-rōzag. In un periodo impossibile da stabilire con certezza la versione viene fissata nella forma a noi pervenuta nella maggior parte dei manoscritti e per la sua affinità formale probabilmente interpretato come inno e perciò incluso nell'innario avestico.

Measurement of the unpolarized K+ Lambda and K+ Sigma 0 electroproduction cross-section off the proton with KAOS-spectrometer

The new stage of the Mainz Microtron, MAMI, at the Institute for Nuclear Physics of the Johannes Gutenberg-University, operational since 2007, allows open strangeness experiments to be performed. Covering the lack of electroproduction data at very low Q2, p(e,K+)Lambda and p(e,K+)Sigma0, reactions have been studied at Q^2 = 0.036(GeV/c)^2 andrnQ^2 = 0.05(GeV=c)^2 in a large angular range. Cross-section at W=1.75rnGeV will be given in angular bins and compared with the predictions of Saclay-Lyon and Kaon Maid isobaric models. We conclude that the original Kaon-Maid model, which has large longitudinal couplings of the photon to nucleon resonances, is unphysical. Extensive studies for the suitability of silicon photomultipliers as read out devices for a scintillating fiber tracking detector, with potential applications in both positive and negative arms of the spectrometer, will be presented as well.

Kinetische Studien zur OH-Bildung über die Reaktionen von HO 2 mit organischen Peroxyradikalen

Es wurde untersucht, wie sich das Substitutionsmuster organischer Peroxyradikale (RO2) auf die Ratenkonstante k1 und die Verzweigungsverhältnisse α, β und γ der Reaktionen von RO2 mit HO2 auswirkt. Die Effekte der Deuterierung von HO2 wurden ebenfalls studiert. Für zwei RO2 wurde zusätzlich das UV-Absorptionsspektrum bestimmt.rnrn αrnRO2 + HO2 → RO + OH + O2 R1arnrn βrn → RO2H + O2 R1brnrn γrn → ROH + O3 R1crnrnIn dieser Arbeit wurde ein neues Experiment aufgebaut. Für die direkte und zeitaufgelöste Messung der OH-Konzentration wurde das Verfahren der Laser-induzierten Fluoreszenz angewendet. Die Radikalerzeugung erfolgte mittels gepulster Laserphotolyse, wodurch unerwünschte Nebenreaktionen weitgehend unterdrückt werden konnten. Mittels transienter Absorptionsspektroskopie konnten die Menge der photolytisch erzeugten Radikale bestimmt und die Ozonbildung über R1c quantifiziert werden. Für die Auswertung wurden kinetische Modelle numerisch an die Messdaten angepasst. Um die experimentellen Unsicherheiten abzuschätzen, wurde ein Monte-Carlo-Ansatz gewählt.rnrnk1 und α reagieren sehr empfindlich auf Veränderungen des RO2-Substitutionsmusters. Während sich eine OH-Bildung für das unsubstituierte C2H5O2 (EtP) mit α EtP ≤ 5 % nicht nachweisen lässt, stellt R1a bei den α-Oxo-substituierten H3CC(O)O2 (AcP) und HOCH2C(O)O2 (HAP) mit α AcP = (63 ± 11) % bzw. α HAP = (69 ± 12) % den Hauptkanal dar. Wie die mit α HEP = (10 ± 4) % geringfügige OH-Bildung bei HOC2H4O2 (HEP) zeigt, nimmt die OH-Gruppe in β-Stellung weniger Einfluss auf den Wert von α als die Oxogruppe in α-Stellung. Bei der Erzeugung α-Oxo-substituierter RO2 kann ebenfalls OH entstehen (R+O2→RO2/OH). Die Druckabhängigkeit dieser OH-Quelle wurde mit einem innovativen Ansatz bestimmt. Mit γ AcP = (15+5-6) % bzw. γ HAP = (10+2-3) % lässt sich für die Reaktionen der α-Oxo-substituierten RO2 eine erhebliche Ozonbildung nachweisen. Durch die Einführung der α-Oxogruppe steigt k1 jeweils um 1,3 • 10-11 cm3s-1 an, der Effekt der β-Hydroxygruppe ist halb so groß (k1 AcP = (2,0 ± 0,4) • 10-11 cm3s-1, k1 HAP = (2,6 ± 0,4) • 10-11 cm3s-1). Das Verzweigungsverhältnis α steigt weiter, wenn das HO2 deuteriert wird (α AcP,iso = (80 ± 14) %, k1 AcP,iso = (2,1 ± 0,4) • 10-11 cm3s-1). Vergleiche mit älteren Studien zeigen, dass die OH-Bildung über R1a bislang deutlich unterschätzt worden ist. Die möglichen Ursachen für die Unterschiede zwischen den Studien werden ebenso diskutiert wie die Hintergründe der beobachteten Substituenteneffekte.

Ago e filo 3.0: quali opportunità di business per l'artigianato locale con l'evoluzione dei social? C'è ancora spazio e visibilità per loro?

Con l’evoluzione dei social network e degli strumenti del 2.0 (blog, wiki, forum), internet si avvia verso nuove forme di business cui artigiani e pmi possono sfruttare per nuove opportunità, unendo social network e e-commerce e capire come si è evoluto il processo di creazione e finanziamento di un prodotto. La tesi è un viaggio per scoprire quali sono queste nuove opportunità per chi pratica artigianato a livello locale, e come è cambiata la figura stessa dell’artigiano, tra questi un nuovo movimento chiamato makers, che sfruttano i nuovi strumenti, tra cui anche mezzi rivoluzionari come la stampante 3D ora accessibile a tutti per creare oggetti e nuove idee. Sarà necessario capire quali sono le vetrine online dove e come poter vendere i nostri prodotti e profilare attraverso una segmentazione l’utente medio che già utilizza il social-commerce. In seguito si tratta il caso empirico di una start-up italiana, Blomming, una dei primi a differenziarsi dagli altri marketplace più famosi come contenitore adatto ad artigiani, ma non solo. Si seguiranno le varie fasi di crescita da un’idea, introduzione nel mercato fino alla direzione a cui si sta avviando con le ultime novità effettuando un’analisi dei rischi. Infine per capire tendenze e storie di chi sta già usando queste piattaforme è stato necessario fare un profilo dell’artigiano fai-da-te medio intervistando, e successivamente creando grafici, 100 artigiani che già vendono online.

The effect of a slow mode of BMP-2 delivery on the inflammatory response provoked by bone-defect-filling polymeric scaffolds

We investigated the inflammatory response to, and the osteoinductive efficacies of, four polymers (collagen, Ethisorb, PLGA and Polyactive) that bore either an adsorbed (fast-release kinetics) or a calcium-phosphate-coating-incorporated (slow-release kinetics) depot of BMP-2. Titanium-plate-supported discs of each polymer (n = 6 per group) were implanted at an ectopic (subcutaneous) ossification site in rats (n = 48). Five weeks later, they were retrieved for a histomorphometric analysis of the volumes of ectopic bone and foreign-body giant cells (a gauge of inflammatory reactivity), and the degree of polymer degradation. For each polymer, the osteoinductive efficacy of BMP-2 was higher when it was incorporated into a coating than when it was directly adsorbed onto the material. This mode of BMP-2 carriage was consistently associated with an attenuation of the inflammatory response. For coated materials, the volume density of foreign-body giant cells was inversely correlated with the volume density of bone (r(2) = 0.96), and the volume density of bone was directly proportional to the surface-area density of the polymer (r(2) = 0.97). Following coating degradation, other competitive factors, such as the biocompatibility and the biodegradability of the polymer itself, came into play.

5a-Butyl-1,3,8,10-tetra-chloro-7,13-bis-(4-nitro-benzo-yl)-5a,6a,12a,12b-tetra-hydro-7H,13H-thieno[2,3-b:4,5-b']bis-(1,4-benzoxazine)

The title compound, C(34)H(24)Cl(4)N(4)O(8)S, is a linear penta-cyclic system formed of two substituted benzoxazinyl groups fused to 2-n-butyl-tetra-hydro-thio-phene. The oxazine ring, which is fused to the n-butyl-substituted side of the thio-phene ring, is in a boat conformation. The other fused oxazine ring and the tetra-hydro-thiene ring are each in an envelope conformation. The bridgehead C atom alpha to both the S and N atoms forms the flap of each envelope. This results in a twist of the penta-cyclic system such that the dihedral angle between the terminal dichloro-benzene rings is 82.92 (8)°. In the crystal, inversion-related mol-ecules form a weakly hydrogen-bonded dimer, with two C-H⋯O inter-actions between an H atom on the oxazine ring and an amide O atom. Additionally, C-H⋯O inter-actions occur between an H atom on a screw-related nitro-benzene ring and an O atom on the nitro-benzene ring of one mol-ecule. One of the Cl atoms and the butyl group are disordered over two sets of sites with occupancy ratios of 0.94 (2):0.06 (2) and 0.624 (4):0.376 (4), respectively.

Novel positron emission tomography/computed tomography of diffuse parenchymal lung disease combining a labeled somatostatin receptor analogue and 2-deoxy-2[¹⁸F]fluoro-D-glucose

We prospectively investigated the potential of positron emission tomography (PET) using the somatostatin receptor (SSTR) analogue ⁶⁸Ga-DOTATATE and 2-deoxy-2[¹⁸F]fluoro-D-glucose (¹⁸F-FDG) in diffuse parenchymal lung disease (DPLD). Twenty-six patients (mean age 68.9 ± 11.0 years) with DPLD were recruited for ⁶⁸Ga-DOTATATE and ¹⁸F-FDG combined PET/high-resolution computed tomography (HRCT) studies. Ten patients had idiopathic pulmonary fibrosis (IPF), 12 patients had nonspecific interstitial pneumonia (NSIP), and 4 patients had other forms of DPLD. Using PET, the pulmonary tracer uptake (maximum standardized uptake value [SUV(max)]) was calculated. The distribution of PET tracer was compared to the distribution of lung parenchymal changes on HRCT. All patients demonstrated increased pulmonary PET signal with ⁶⁸Ga-DOTATATE and ¹⁸F-FDG. The distribution of parenchymal uptake was similar, with both tracers corresponding to the distribution of HRCT changes. The mean SUV(max) was 2.2 ± 0.7 for ⁶⁸Ga-DOTATATE and 2.8 ± 1.0 (t-test, p  =  .018) for ¹⁸F-FDG. The mean ⁶⁸Ga-DOTATATE SUV(max) in IPF patients was 2.5 ± 0.9, whereas it was 2.0 ± 0.7 (p  =  .235) in NSIP patients. The correlation between ⁶⁸Ga-DOTATATE SUV(max) and gas transfer (transfer factor of the lung for carbon monoxide [TLCO]) was r  =  -.34 (p  =  .127) and r  =  -.49 (p  =  .028) between ¹⁸F-FDG SUV(max) and TLCO. We provide noninvasive in vivo evidence in humans showing that SSTRs may be detected in the lungs of patients with DPLD in a similar distribution to sites of increased uptake of ¹⁸F-FDG on PET.

Outcome evaluation of early placed maxillary anterior single-tooth implants using objective esthetic criteria: a cross-sectional, retrospective study in 45 patients with a 2- to 4-year follow-up using pink and white esthetic scores

BACKGROUND: To validate the concept of early implant placement for use in the esthetically sensitive anterior maxilla, clinical trials should ideally include objective esthetic criteria when assessing outcome parameters. METHODS: In this cross-sectional, retrospective 2- to 4-year study involving 45 patients treated with maxillary anterior single-tooth implants according to the concept of early implant placement, a novel comprehensive index, comprising pink esthetic score and white esthetic score (PES/WES; the highest possible combined score is 20), was applied for the objective esthetic outcome assessment of anterior single-tooth implants. RESULTS: All 45 anterior maxillary single-tooth implants fulfilled strict success criteria for dental implants with regard to osseointegration, including the absence of peri-implant radiolucency, implant mobility, suppuration, and pain. The mean total PES/WES was 14.7 +/- 1.18 (range: 11 to 18). The mean total PES of 7.8 +/- 0.88 (range: 6 to 9) documents favorable overall peri-implant soft tissue conditions. The two PES variables facial mucosa curvature (1.9 +/- 0.29) and facial mucosa level (1.8 +/- 0.42) had the highest mean values, whereas the combination variable root convexity/soft tissue color and texture (1.2 +/- 0.53) proved to be the most difficult to fully satisfy. Mean scores were 1.6 +/- 0.5 for the mesial papilla and 1.3 +/- 0.5 for the distal papilla. A mean value of 6.9 +/- 1.47 (range: 4 to 10) was calculated for WES. CONCLUSIONS: This study demonstrated that anterior maxillary single-tooth replacement, according to the concept of early implant placement, is a successful and predictable treatment modality, in general, and from an esthetic point of view, in particular. The suitability of the PES/WES index for the objective outcome assessment of the esthetic dimension of anterior single-tooth implants was confirmed. However, prospective clinical trials are needed to further validate and refine this index.

BMP-2 liberated from biomimetic implant coatings induces and sustains direct ossification in an ectopic rat model

INTRODUCTION: Using a rat model, we evaluated the kinetics and histomorphometry of ectopic bone formation in association with biomimetic implant coatings containing BMP-2. MATERIALS AND METHODS: One experimental and three control groups were set up: titanium-alloy discs coated with a biomimetically co-precipitated layer of calcium phosphate and BMP-2 [1.7 microg per disc (incorporated-BMP group)]; uncoated discs (control); discs biomimetically coated with a layer of calcium phosphate alone (control); and discs biomimetically coated with a layer of calcium phosphate bearing superficially adsorbed BMP-2 [0.98 microg per disc (control)]. Discs (n = 6 per group) were implanted subcutaneously in rats and retrieved at 7-day intervals over a period of 5 weeks for kinetic, histomorphometrical, morphological and histochemical analyses. RESULTS: In the incorporated-BMP-2 group, osteogenic activity was first observed 2 weeks after implantation and thereafter continued unabated until the end of the monitoring period. The net weekly rates of bone formation per disc were 5.8 mm3 at 2 weeks and 3.64 mm3 at 5 weeks. The total volumes of bone formed per disc at these junctures were 5.8 mm3 and 10.3 mm3, respectively. Bone tissue, which was formed by a direct ossification mechanism, was deposited at distances of up to 340 microm from the implant surfaces. The biomimetic coatings were degraded gradually, initially by foreign body giant cells alone and then also by osteoclasts. Forty percent of the coating material (and thus presumably of the incorporated BMP-2) remained at the end of the monitoring period. Hence, 60% of the incorporated BMP-2 had been released. At this 5-week juncture, no bone tissue was associated with any of the control implants. CONCLUSION: BMP-2 incorporated into biomimetic calcium phosphate coatings is capable not only of inducing bone formation at an ectopic site in vivo but also of doing so with a very high potency at a low pharmacological level, and of sustaining this activity for a considerable period of time. The sustainment of osteogenic activity is of great clinical importance for the osseointegration of dental and orthopedic implants.

Bone morphogenetic protein 2 incorporated into biomimetic coatings retains its biological activity

We have previously shown that proteins can be incorporated into the latticework of calcium phosphate layers when biomimetically coprecipitated with the inorganic components, upon the surfaces of titanium-alloy implants. In the present study, we wished to ascertain whether recombinant human bone morphogenetic protein 2 (rhBMP-2) thus incorporated retained its bioactivity as an osteoinductive agent. Titanium alloy implants were coated biomimetically with a layer of calcium phosphate in the presence of different concentrations of rhBMP-2 (0.1-10 microg/mL). rhBMP-2 was successfully incorporated into the crystal latticework, as revealed by protein blot staining. rhBMP-2 was taken up by the calcium phosphate coatings in a dose-dependent manner, as determined by ELISA. Rat bone marrow stromal cells were grown directly on these coatings for 8 days. Their osteogenicity was then assessed quantitatively by monitoring alkaline phosphatase activity. This parameter increased as a function of rhBMP-2 concentrations within the coating medium. rhBMP-2 incorporated into calcium phosphate coatings was more potent in stimulating the alkaline phosphatase activity of the adhering cell layer than was the freely suspended drug in stimulating that of cell layers grown on a plastic substratum. This system may be of osteoinductive value in orthopedic and dental implant surgery.

Effect of a chitosan additive to a Sn(2+)-containing toothpaste on its anti-erosive/anti-abrasive efficacy-a controlled randomised in situ trial

OBJECTIVES It is well known that Sn(2+) is a notable anti-erosive agent. There are indications that biopolymers such as chitosan can enhance the effect of Sn(2+), at least in vitro. However, little information exists about their anti-erosive/anti-abrasive in situ effects. In the present in situ study, the efficacy of Sn(2+)-containing toothpastes in the presence or absence of chitosan was tested. METHODS Ten subjects participated in the randomised crossover study, wearing mandibular appliances with human enamel specimens. Specimens were extraorally demineralised (7 days, 0.5 % citric acid, pH 2.6; 6 × 2 min/day) and intraorally exposed to toothpaste suspensions (2 × 2 min/day). Within the suspension immersion time, one half of the specimens were additionally brushed intraorally with a powered toothbrush (5 s, 2.5 N). Tested preparations were a placebo toothpaste (negative control), two experimental toothpastes (F/Sn = 1,400 ppm F(-), 3,500 ppm Sn(2+); F/Sn/chitosan = 1,400 ppm F(-), 3,500 ppm Sn(2+), 0.5 % chitosan) and an SnF2-containing gel (positive control, GelKam = 3,000 ppm Sn(2+), 1,000 ppm F(-)). Substance loss was quantified profilometrically (μm). RESULTS In the placebo group, tissue loss was 11.2 ± 4.6 (immersion in suspension) and 17.7 ± 4.7 (immersion in suspension + brushing). Immersion in each Sn(2+)-containing suspension significantly reduced tissue loss (p ≤ 0.01); after immersion in suspension + brushing, only the treatments with GelKam (5.4 ± 5.5) and with F/Sn/chitosan (9.6 ± 5.6) significantly reduced loss [both p ≤ 0.05 compared to placebo; F/Sn 12.8 ± 6.4 (not significant)] CONCLUSION Chitosan enhanced the efficacy of the Sn(2+)-containing toothpaste as an anti-erosive/anti-abrasive agent. CLINICAL RELEVANCE The use of Sn(2+)- and chitosan-containing toothpaste is a good option for symptomatic therapy in patients with regular acid impacts.

A Restriction-Centered Theory of Reasoning and Computation to materialize a Web 3.0

Researchers suggest that personalization on the Semantic Web adds up to a Web 3.0 eventually. In this Web, personalized agents process and thus generate the biggest share of information rather than humans. In the sense of emergent semantics, which supplements traditional formal semantics of the Semantic Web, this is well conceivable. An emergent Semantic Web underlying fuzzy grassroots ontology can be accomplished through inducing knowledge from users' common parlance in mutual Web 2.0 interactions [1]. These ontologies can also be matched against existing Semantic Web ontologies, to create comprehensive top-level ontologies. On the Web, if augmented with information in the form of restrictions andassociated reliability (Z-numbers) [2], this collection of fuzzy ontologies constitutes an important basis for an implementation of Zadeh's restriction-centered theory of reasoning and computation (RRC) [3]. By considering real world's fuzziness, RRC differs from traditional approaches because it can handle restrictions described in natural language. A restriction is an answer to a question of the value of a variable such as the duration of an appointment. In addition to mathematically well-defined answers, RRC can likewise deal with unprecisiated answers as "about one hour." Inspired by mental functions, it constitutes an important basis to leverage present-day Web efforts to a natural Web 3.0. Based on natural language information, RRC may be accomplished with Z-number calculation to achieve a personalized Web reasoning and computation. Finally, through Web agents' understanding of natural language, they can react to humans more intuitively and thus generate and process information.

Measurement of the jet radius and transverse momentum dependence of inclusive jet suppression in lead-lead collisions at sqrtsNN=2.76 TeV with the AT detector

Measurements of inclusive jet suppression in heavy ion collisions at the LHC provide direct sensitivity to the physics of jet quenching. In a sample of lead-lead collisions at root S-NN = 2.76 TeV corresponding to an integrated luminosity of approximately 7 mu b(-1), ATLAS has measured jets with a calorimeter system over the pseudorapidity interval vertical bar eta vertical bar < 2.1 and over the transverse momentum range 38 < pT <210 GeV. Jets were reconstructed using the anti-k(t) algorithm with values for the distance parameter that determines the nominal jet radius of R = 0.2, 0.3, 0.4 and 0.5. The centrality dependence of the jet yield is characterized by the jet "central-to-peripheral ratio," R-CP. Jet production is found to be suppressed by approximately a factor of two in the 10% most central collisions relative to peripheral collisions. R-CP varies smoothly with centrality as characterized by the number of participating nucleons. The observed suppression is only weakly dependent on jet radius and transverse momentum. These results provide the first direct measurement of inclusive jet suppression in heavy ion collisions and complement previous measurements of dijet transverse energy imbalance at the LHC.

Dominance of chemokine ligand 2 and matrix metalloproteinase-2 and -9 and suppression of pro-inflammatory cytokines in the epidural compartment after intervertebral disc extrusion in a canine model

BACKGROUND CONTEXT In canine intervertebral disc (IVD) disease, a useful animal model, only little is known about the inflammatory response in the epidural space. PURPOSE To determine messenger RNA (mRNA) expressions of selected cytokines, chemokines, and matrix metalloproteinases (MMPs) qualitatively and semiquantitatively over the course of the disease and to correlate results to neurologic status and outcome. STUDY DESIGN/SETTING Prospective study using extruded IVD material of dogs with thoracolumbar IVD extrusion. PATIENT SAMPLE Seventy affected and 13 control (24 samples) dogs. OUTCOME MEASURES Duration of neurologic signs, pretreatment, neurologic grade, severity of pain, and outcome were recorded. After diagnostic imaging, decompressive surgery was performed. METHODS Messenger RNA expressions of interleukin (IL)-1β, IL-2, IL-4, IL-6, IL-8, IL-10, tumor necrosis factor (TNF), interferon (IFN)γ, MMP-2, MMP-9, chemokine ligand (CCL)2, CCL3, and three housekeeping genes was determined in the collected epidural material by Panomics 2.0 QuantiGene Plex technology. Relative mRNA expression and fold changes were calculated. Relative mRNA expression was correlated statistically to clinical parameters. RESULTS Fold changes of TNF, IL-1β, IL-2, IL-4, IL-6, IL-10, IFNγ, and CCL3 were clearly downregulated in all stages of the disease. MMP-9 was downregulated in the acute stage and upregulated in the subacute and chronic phase. Interleukin-8 was upregulated in acute cases. MMP-2 showed mild and CCL2 strong upregulation over the whole course of the disease. In dogs with severe pain, CCL3 and IFNγ were significantly higher compared with dogs without pain (p=.017/.020). Dogs pretreated with nonsteroidal anti-inflammatory drugs revealed significantly lower mRNA expression of IL-8 (p=.017). CONCLUSIONS The high CCL2 levels and upregulated MMPs combined with downregulated T-cell cytokines and suppressed pro-inflammatory genes in extruded canine disc material indicate that the epidural reaction is dominated by infiltrating monocytes differentiating into macrophages with tissue remodeling functions. These results will help to understand the pathogenic processes representing the basis for novel therapeutic approaches. The canine IVD disease model will be rewarding in this process.

Prevalence of type 2 diabetes is higher in peripheral artery disease than in coronary artery disease patients.

Type 2 diabetes mellitus and pre-diabetes are risk factors for atherosclerosis and are highly prevalent in patients with coronary artery disease. However, the prevalence of impaired glucose metabolism in patients with peripheral artery disease is not as well elucidated. We aimed at comparing prevalence rates of type 2 diabetes mellitus and pre-diabetes, which were diagnosed according to the current American Diabetes Association criteria, among 364 patients with peripheral artery disease, 529 patients with coronary artery disease and 383 controls. The prevalence of type 2 diabetes mellitus in peripheral artery disease patients was 49.7%. It was significantly higher in these patients than in coronary artery disease patients (34.4%; p < 0.001) and controls (21.4%; p < 0.001). Adjusted for sex, age and body mass index, odds ratios for type 2 diabetes mellitus were 2.0 (95% confidence interval 1.5-2.6) comparing the peripheral artery disease group with the coronary artery disease group (p < 0.001) and 4.0 (2.8-5.8) comparing the peripheral artery disease group with controls (p < 0.001). The prevalence of pre-diabetes among non-diabetic subjects was high in all three study groups (64.5% in peripheral artery disease patients, 63.4% in coronary artery disease patients and 61.8% in controls), without significant between-group differences. In conclusion, the prevalence of type 2 diabetes mellitus is even higher in peripheral artery disease patients than in coronary artery disease patients. This observation underlines the need to consider impaired glucose regulation in the management of peripheral artery disease.
