Purpose : The aim of the present study was to evaluate prospectively the clinical outcomes of a prototype one-piece zirconia implants after a -18 month follow-up. Material and methods : 20 prototype one-piece zirconia implants were placed and immediately restored with provisional protheses. A flapless or a minimally invasive approach was used for every implant placement. Bone levels were recorded at baseline and -1 year. Surgical, biological and prosthetic complications were also assessed. Results : The study included 15 patients. Most of the implants (90%) were placed at the anterior maxilla. Six of the implant sites were previously augmented with autogenous bone block grafts, 8 were managed with socket preservation techniques, 3 implants were immediatly placed after extraction and one implant was placed simultanously with a guided bone regeneration. Insertion torque (> 30N/cm2) was reached for all implants. The implant survival and success rates reached respectively 100% and 95%. One implant abutment fractured at placement because of an excessive insertion torque (> 50 N/cm2). No further complication occurred. Conclusion : From the preliminary results of this prospective clinical study, one-piece zirconia implants seem to success after 1 year despite they were often placed in critical clinical situtations (bone augmentations) and immediately restored. Further follow-up is needed to evaluate the long-term outcomes. [less ▲]

N-Vinylcaprolactam (NVCL) was copolymerized statistically for the first time in a controlled manner with hydrophilic N-vinylamide or hydrophobic vinylester monomers in order to precisely tune up and down the lower critical solution temperature (LCST) of the resulting copolymers. The incorporation of these segments in complex architectures was also considered. Several narrowly distributed NVCL-based copolymers were prepared by cobalt-mediated radical polymerization (CMRP) using the bis-(acetylacetonato)cobalt(II) complex as a controlling agent and N-methyl-N-vinylacetamide (NMVA), N-vinylacetamide (NVA), vinyl acetate (VAc) or vinyl pivalate (VPi) as comonomers. PNVCL-containing block copolymers having two discrete LCSTs were also synthesized following a one-pot strategy based on the sequential CMRP of NVCL followed by the copolymerization of NMVA with the residual NVCL. Upon gradual heating of aqueous solutions of such double thermoresponsive copolymers, we noticed a transition from free chains to micelles before full dehydration and collapse of the block copolymers. These advances represent a significant step towards the development of a platform based on thermoresponsive PNVCL copolymers with a single phase separation or multistep assembly behaviors. [less ▲]

The trisaccharide Gal alpha 1-->3Gal beta 1-->4GlcNAc beta 1-->O-(CH2)8COOCH3 was enzymatically synthesized, with in situ UDP-Gal regeneration. By combination in one pot of only four enzymes, namely, sucrose synthase, UDP-Glc 4'-epimerase, UDP-Gal:GlcNAc beta 4-galactosyltransferase and UDP-Gal:Gal beta 1-->4GlcNAc alpha 3-galactosyltransferase, Gal alpha 1-->3Gal beta 1-->4GlcNAc beta 1-->O-(CH2)8COOCH3 was formed in a 2.2 mumol ml-1 yield starting from the acceptor GlcNAc beta 1-->O-(CH2)8COOCH3. This is an efficient and convenient method for the synthesis of the Gal alpha 1-->3Gal beta 1-->4GlcNAc epitope which pays an important role in various biological and immunological processes.

BACKGROUND: The aim was to ascertain the 1-year clinical outcomes of 1,234 patients who underwent implantations of sirolimus-eluting stents (SES) for acute myocardial infarction (MI) in the multinational e-SELECT registry. METHODS: Fifteen thousand and one hundred and forty-seven patients treated with SES were entered in the e-SELECT registry, of whom 1,234 presented within <24 hours of onset of acute MI. RESULTS: At 1 year, the rates of major adverse cardiac events (MACE) (5.5% vs. 4.8%; P = 0.28) were similarly low in the acute and no acute MI groups. The rates of definite/probable stent thrombosis (ST) were higher in the acute MI group (2.1%vs; 0.88%, P < 0.001). ST was a strong independent predictor of death at 1 year (HR 13.4; 95% CI 5.0, 36.0; P < 0.001) and MI (HR 58.9; 95% CI 26.9, 129.1; P < 0.001). Dual antiplatelet therapy (DAPT) compliance at 6 months was 96.0% in the acute MI versus 94.5% in the no acute MI group (P = 0.03). CONCLUSION: In selected patients presenting within <24 hours of acute MI onset and highly compliant with DAPT, SES implantation was associated with similar rates of MACE, though higher rates of ST, as compared to no acute MI patients.

Baseline Ankle-Brachial Blood Pressure Index (ABI base) was measured in 85 chronic hemodialysis (HD) patients in 2005, giving a 41% prevalence of peripheral arterial disease (ABI < 0.9). The index was measured 1 year later (ABI 1 year) in 69 BD for whom both screening values were available. The evolution of ABI, 1 year apart, was analyzed in relation to major other cardiovascular (CV) risk factors such as hypertension (lIT), pulse pressure (PP), pulse wave velocity (PWV), phosphocalcic metabolism, and lipids.

OBJECTIVES: To determine Coll2-1, Coll2-1NO(2) and myeloperoxydase (MPO) levels in serum of patients with knee or hip osteoarthritis (OA) before the surgery, 3 months and 1 year after knee or hip replacement. METHODS: Coll2-1, Coll2-1NO(2) and MPO were measured in 103 patients with isolated symptomatic knee or hip OA candidates for joint replacement. Sera were taken the day before surgery, 3 months and 1 year after hip or knee replacement. Coll2-1 and Coll2-1NO(2) immunohistochemistry was performed on biopsies removed from cartilage lesions. RESULTS: Immunostainings revealed the extensive presence of Coll2-1 and Coll2-1NO(2) in the superficial layer of fibrillated cartilage and around some chondrocytes clusters. Three months after joint replacement, Coll2-1 and MPO serum levels were decreased and even reached the reference value for Coll2-1. By contrast, Coll2-1NO(2) levels remained elevated. At 1-year follow-up, Coll2-1 levels remained at the reference value, MPO levels were similar to those measured at 3 months, and Coll2-1NO(2) levels were unchanged and comparable to the pre-surgery values. However, in patients with pre-surgery values above the median (more than 0.42 nM), Coll2-1NO(2) levels significantly and progressively decreased post-operatively, but tended towards an increase in patients with pre-surgery Coll2-1NO(2) values below the median. CONCLUSIONS: The normalisation of Coll2-1 levels 3 months after surgery indicates that Coll2-1 is a disease-specific marker that is sensitive to the structural changes occurring in a single joint. Furthermore, the immunohistochemical findings are consistent with the concept that the major source of serum Coll2-1 is the damaged articular cartilage. Finally, serum MPO levels decreased after joint replacement indicating that neutrophil activation occurs in OA joints, even in the late stage of the disease. [less ▲]

Introduction: Infiltration of PRP may be used as a recent therapeutic option for chronic tendinopathies The aim of the current study is to evaluate the clinic and the return to sports activities in patients with chronic upper patellar tendinopathies 1 year after 1 infiltration of PRP. Material and methods: The follow-up of 20 subjects who beneficed from 1 infiltration of PRP was made before infiltration, after 3 months and 1 year after infiltration; it was made as follow: VAS, IKDC and VISA-P scores. Moreover, they had to answer an information questionnaire concerning their life and sports activities. Results: Seventy percents of patients reported a favourable evolution with decrease of pain, 10% did never report any improvement and 20% were treated surgically. Eighty-seven percents returned to sports activities without any pain, and 50% of them recovered the same sport level. VAS has significantly (p<0.0001) dropped, IKDC significantly improved (p=0.0007) and VISA-P also significantly increased (p=0.0087) over the follow-up of 1 year. Discussion: This study confirms that a local injection of PRP coupled with a program of eccentric rehabilitation through a chronic Jumper's knee, improves painful symptoms and the functionality of the subjects’ knee up to a follow-up of 1 year.
