    On the radiographs, only 4.88% of the patients present advanced osteoarthritis. selleck products It was not possible to identify risk factors related to a worse outcome after surgery.

    The arthroscopic Bankart repair with suture anchors is considered the gold standard for treatment of anterior glenohumeral instability. The long-term follow-up shows a favourable outcome, with a redislocation rate of 9% and low complication rate.

    To evaluate the short term and 1-year follow-up functional effects of a physiotherapy programme in patients over 60 years of age with massive and irreparable Rotator Cuff (RC) tear.

    A total of 96 patients with massive and irreparable RC tear were prospectively recruited. All patients were treated with a 12-week physiotherapy programme. Three evaluations were performed, at the beginning, at the end of the treatment and at one year of follow-up. The Constant-Murley questionnaire was used to assess shoulder function, the DASH questionnaire for upper limb function, and the Visual Analogue Scale (VAS) for pain intensity.

    At the end of the treatment, all the variables showed a clinically and statistically significant difference (p<.05). At one year of follow-up, the Constant-Murley showed an increase of 26.5 points (Cohen’s d=1.7; 95% CI 23.5-29.5; p<.001), DASH showed a decrease of 31.4 points (Cohen’s d=2.2; 95% CI 28.5-34.3; p<.001), and the VAS showed a decrease of 3.9cm (Cohen’s d=3.6; 95% CI 3.6-4.1; p<.001).

    In the short term and 1-year follow-up, a physiotherapy programme showed clinically and statistically significant results in all functional variables in patients older than 60 years with massive and irreparable RC tear.

    Surveillance systems make it possible to analyze the trends of infections associated with hip arthroplasty. The aim of this study is to determine risk factors associated with surgical site infection (SSI) and mortality following total hip arthroplasty (THA) or hemiarthroplasty (HHA).

    Observational study including individuals ≥18 years who underwent THA or HHA between January 2007 and December 2017. Incidences of SSI were compared with the national rates according to NNIS indexes. Risk factors for SSI and mortality were evaluated using multiple logistic regression model.

    In THA, an association with a higher risk of SSI was found with hospital stay (OR 1.08; 95% CI 1.02-1.15; p=.007). In HHA, hospital stay was associated with a higher risk of SSI (OR 1.05; 95% CI 1.02-1.08; p=.001), as also happened with obesity (OR 13.28; 95% CI 2.68-65.74; p=.002), while inadequate antibiotic prophylaxis was associated with a higher risk of mortality (OR 4.69; 95% CI 1.01-21.74; p=.048).

    In THA, hospital stay was associated with an increased risk of SSI. In HHA this association is found with hospital stay and obesity, while inadequate antibiotic therapy was associated with mortality.

Access to the individual oxygen isotope compositions (δ18O) in the lignin monomeric units is, however, challenging as depolymerization of lignin to release the monomeric units may cause isotope fractionation. We have developed a novel method to measure the δ18O of the three oxygens (O-3, O-4 and O-5) attached to the aromatic ring of the monomeric units (bearing no oxygen in their side chains) releasable by highly selective W2C/AC (tungsten carbide supported by activated carbon)-catalyzed hydrogenolysis of lignin. O-4 is obtained by measuring the δ18O of H-type monomeric unit, while O-3 and O-5 can be calculated following isotope mass balance between H, G and S-type monomeric units measurable simultaneously with GC/Py/IRMS (gas chromatography-pyrolysis-isotope ratio mass spectrometry). The measurement precisions are better than 1.15 mUr and 4.15 mUr at molecular and positional levels, respectively. It was shown that there were a δ18OH > δ18OG > δ18OS isotopic order in the herbaceous plant lignin and an (inclusive) opposite order in woody plant lignin. Such differences in isotopic order is likely to be caused by the fact that both L-tyrosine, which carries an 18O-enriched leaf water signal, and L-phenylalanine, which carries mainly a molecular O2 isotopic signal, serve as the precursors for lignin biosynthesis in herbaceous plants while only the latter serves as precursor for lignin biosynthesis in woody plants. We have highlighted the potential application of such molecular and positional levels isotopic signals in plant physiological, metabolic, lignin biosynthetic and climate studies.Colorimetric localized surface plasmon resonance (LSPR) as analytical response is applied for a wide number of chemical sensors and biosensors. However, the dependence of different factors, such as size distribution of nanoparticles (NPs), shape, dielectric environment, inter-particle distance and matrix, among others, can provide non-reliable results by UV-vis spectrometry in complex matrices if NP assessment is not carried out, particularly at low levels of analyte concentrations. Miniaturized liquid chromatography, capillary (CapLC) and nano (NanoLC), coupled on line with in-tube solid phase microextraction (IT-SPME) is proposed for the first time for both, controlling suitability of used noble metal NP dispersions and developing plasmonic assays. Several capped noble NPs and target analytes were tested from variations in the chromatographic profiles obtained by using diode array detection. The IT-SPME step, which influenced the chromatographic fingerprint provided by noble NP dispersions, was studied by asymmetrical flow field flow fractionation (AF4) too.
