Published: January 2015

Objectives: Crank test and the radiological Sulcus sign are described as reliable parameters of shoulder instability. Our objective is to establish by these methods, the clinical and x- ray stability outcome in patients with arthroscopic Bankart repair. Methods: We studied 30 patients, 21 males and 9 female, average age 31 years (17-45), with ISIS average of 3.5 (2-5), all the cases presented Bankart lesion. All patients were treated on by the same team, all the surgeries were did by the same arthroscopic technique. Average follow up 21 months (6 - 36). The radiological and clinic assessment was done by the same surgeon to the 3, 6, 12 and 24 months postoperatively. Results: We found In 25 patients a negative result of clinical - x ray evaluation, 4 patients had crank test positive,1 patient presented both, Crank test and positive Sulcus sign. Discussion: These clinical and radiological tests are a practical tool that reproduced the gleno humeral postsurgical instability; In addition, it was found that the positive cases of instability coincide with a 6 points preoperative ISIS evaluation. Conclusion: We can infer that both, Crank test as Sulcus sign are reliable parameters for evaluate postoperative instability. We know that the success of the surgical outcome is the preoperative screening of the patient.

Published: January 2015

Objectives: The aim of this study was to evaluate the results of autologous osteochondral transfer for the treatment of cartilage defects in 2 groups of patients: The first with an isolated osteochondral injury and the other with associated anterior cruciate ligament (ACL) injury treated in one stage surgery Materials and Methods: We retrospectively evaluated 25 patients with symptomatic focal full-thickness chondral lesions in the femoral condyles during the years 2003-2009, with a minimum of 5 years of follow up. The patients were divided into 2 groups: Group A: 10 patients with associated ACL injury, and Group B: 15 patients with an isolated osteochondral lesion. Clinical outcome was analyzed by Lysholm and IKDC scores. Results: There was an improvement of all scores in both groups. There were no significant differences between the groups in the IKDC (82/84) and Lysholm (87/86) scores. The mean age at the time of assessment for group A was 46 years and 44 for the group B. The mid term follow-up was 96 months for group A and 103 months for group B. Two complications were recorded in group A: 1 infection and 1 arthrofibrosis. 2 complicationsoccurred in group B: 2 arthrofibrosis. Conclusion: The results of the mosaicplasty for the focal full-thickness chondral lesions in the femoral condyles are favorable after 5 years of follow up. There was no difference between the associated or not ACL injury.

Objectives: The aim of our study was to determine the morbidity and mortality at 3 and 6 months after surgery of patients undergoing total knee arthroplasty at the Unidad de Cirugía del Aparato Locomotor (UCAL) of the Asociación Española de Socorros Mutuos (a medical institution). Methods: In a prospective single cohortstudy, all patients undergoing primary totalkneearthroplastyatUCALinthe periodbetween Mayand December2011were included, totalizing 140 arthroplasties .A 4 of them failed to complete follow them, so that the results of 136 primary knee arthroplasties using different functional scores were evaluated, findings, comorbidities and complications encounteredwere described. Results: The mortality at follow-upinthe populationwas 0%. Seven patients (5,14%) had complications, including 2patients (1.47%) who had a deep infection. The rateof readmissionandreoperationof our populationwas 4,4% (6 patients). Patients which had no previous comorbidities were a 16,9% The most frequent comorbidity was hypertension present in 65,4% of our patients. All patients with complications had at least 3 comorbidities. Most patients improved their functional dependence by 3% improved their quality of life by 80%, and above all reduced their symptoms especially pain by 66%. Conclusion: All patients with complications had 3 or more comorbidities. In the study population 32% of patients with 3 or more comorbidities suffered any complications. There were no complications in the group of patients with less than 3 comorbidities regardless of age this being statistically significant. We conclude that having 3 or more comorbidities increased the risk of complications this being statistically significant.

Authors: Ballas Juan Pablo Estévez 
Published: January 2015

Purpose: The aim of this study is to access the correlation of Moragas manouver and arthroscopic findings, in the diagnosis of lateral meniscal injury, and to know the imagenologic findings and comparison with arthroscopic results. Methods: 474 arthroscopic procedures were performed with meniscal injuries between 2005-2013. 142 are lateral meniscus lesions (male=94, female=58) by clinical evaluation, average age= 34.4 years old (15-58). MRI was performed in 73 cases, what allowed correlate findings clinical imaging. All clinical tests were realized by the same clinician. Results: Of the 142 patients, 136 were pure external meniscus injuries, (95.77%), 3 were colateral ligament lesions, 1 was a parameniscal cyst, 1 was popliteus tendinosis and 1 was normal. Of 73 cases with MRI evaluation, 68 were a pure lateral meniscal lesions (93.15%), 2 were partial colateral ligament lesions, 1 was popliteus tendinosis, 1 was iliotibial band friction syndrome and 1was lateral condyle avascular necrosis. The comparison between MRI findings and arthroscopic procedure they had no statistical significance. p< 0.0025 Conclusion: The Moragas manouver has a high sensitivity diagnosed for lateral meniscal injury, and the imagenologic correlation with arthroscopic findings was minor in this study (95.77% v/s 93.15%). Discussion: A correct clinic examination and semiologic tests are still important to clinical diagnosis in orthopedics.

Published: January 2015

Objectives: The objective of this study was to analyze whether it is more frequent the presence of a decreased range of motion in the hips of recreational athletes with primary injury of the anterior cruciate ligament (ACL) than in a control group of volunteers without knee pathology. Methods: We included prospectively recreational athletes between 18 and 40 years with an acute ACL injury between January 2011 and January 2013. They were compared with a control group of volunteers recreational athletes without lower limb pathology and in the same range of age. The internal and external rotations passively prior to the point at which the pelvis movement contributes were observed. The results were statistically analyzed using t test for related samples to the hips of patients with ACL injury and t test for independent variables for comparison with the control group. Results: 48 patients with ACL injury and 53 healthy volunteers were evaluated. The ACL group was composed of 32 males and 16 females with an average age of 29.3 years. In the control group 26 males and 27 females were studied with a mean age of 26.6 years. Internal (IR) and external (ER) rotation in the LCA group was 22,9º and 55,5º respectively in the ipsilateral hip and 27,9º and 57,7º in the contralateral. In the control group a 35,9º of IR and 55,2º of ER was observed. The analysis showed an association between ACL injury and hypomotility of the hip further expense of a decrease in internal rotation. The analysis showed an association between ACL injury and hypomotility of the hip at the expense to a greater decrease in internal rotation. Conclusion: We found a statistically significant difference in the mobility of the hips in patients with ACL injury predominantly due to internal rotation, pattern that allows us to interpret this injury not only as an intrinsic etiology of the knee but also of the adjacent joints. We consider very importance to incorporate prevention activities and screening of risk factors regarding to at least high performance athletes.
The role of Th-U minerals in assessing the performance of nuclear waste forms

Published: January 2015

AbstractMaterials designed for nuclear waste disposal include a range of ceramics, glass ceramics and glass waste forms. Those with crystalline phases have provided the momentum for studies of minerals as a means to understand aspects of waste-form crystal chemistry, behaviour in aqueous systems and radiation damage over geological periods of time. Although the utility of natural analogue studies varies, depending upon the degree of analogy to the proposed geological repository and other factors such as chemical composition, the available data suggest that Th-U host phases such as brannerite, monazite, pyrochlore, zircon and zirconolite are resistant generally to dissolution in aqueous fluids at low temperatures. Geochemical durability may or may not extend to hydrothermal systems depending on the specifics of fluid composition, temperature and pressure. At elevated temperatures, for example, davidite may break down to new phase assemblages including titanite, ilmenite and rutile. Perovskite is generally less resistant to dissolution at low temperatures and breaks down to TiO2, releasingA-site cations to the aqueous fluid. Studies of radiation damage indicate that the oxide and silicate phases become amorphous as a result of the gradual accumulation of alpha-recoil collision cascades. Monazite tends to remain crystalline on geological time scales, a very attractive property that potentially eliminates major changes in physical properties such as density and volume, thereby reducing the potential for cracking, which is a major concern for zircon. In spite of recent success in describing the behaviour of Th-U minerals in geological systems, considerable work remains in order to understand theP-T-Xconditions during alteration andT-thistory of the host rocks.
Recent advances in clean-up strategies of waters polluted with sulfonamide antibiotics: a review of sorbents and related properties
Authors: Martucci A. , Braschi I. , Marchese L. , Quartieri S. 
Published: January 2015

AbstractSeveral strategies are available to reduce or eliminate recalcitrant sulfonamide antibiotics (sulfa drugs) from aqueous media. These contaminants are bioactive and ubiquitous pollutants of soils and watercourses and are known to induce bacterial resistance. Here the biological, chemical and physical methods developed over the last 5 years to decontaminate waters polluted with sulfa drugs are reviewed with special attention to procedures that make use of porous adsorbent materials and their applicability to real waters.

AbstractSelected samples of asbestos-containing material (ACM) with different Ca/Si ratios have been treated thermally at 1200°C for 15 min to obtain an ‘end of waste geo-inspired material’. Before and after treatment, micro-Raman spectroscopy allowed the investigation of both powdered and massive samples by directing the laser beam onto crystals with elongated morphology, thin fibres and the matrix. In the raw samples, chrysotile and/or crocidolite were detected. After the thermal treatment, no asbestos phases were identified in the Raman spectra collected on fibrous or fibre-like morphologies. The scanning electron microscopy/energy dispersive spectroscopy investigations confirmed the onset of a pseudomorphic process during annealing, leading to the complete transformation of asbestos minerals into non-hazardous magnesium or calcium magnesium silicates such as forsterite, monticellite, a˚kermanite and merwinite.The identification of such mineral assemblages was inspired by the close inspection of a natural counterpart, the high-temperature contact metamorphic imprint due to the intrusion of a sill into carbonate rocks. The process turned out to occur largely at the solid state and involved substantial mobilization of Ca and Mg to form a spinel phase (namely MgFe2O4) which was recognized in the matrix and within, or close to elongated morphologies.
Phase transitions during compression of thaumasite, Ca3Si(OH)6(CO3)(SO4)·12H2O: A high-pressure synchrotron powder X-ray diffraction study

AbstractThe high-pressure behaviour of the thaumasite structure was investigated using synchrotron powder X-ray diffraction, up to 19.5 GPa. Based on Rietveld refinements, thaumasite retained the roompressure P63 space group throughout the whole investigated pressure range while the pressure dependence of the refined unit-cell parameters can be cast into three different compression regimes, each corresponding to a different thaumasite phase (th-I, th-II and th-III) related by isosymmetric phase transitions. In particular, the phase transition in the 7.40–15.02 GPa P-range (i.e. from th-II to th-III) is associated with an inversion of the axial bulk moduli which, by analogy with ettringite, can be rationalized as due to a change in the relative strengths of the iono-covalent bonds along the [Ca3Si(OH)6(H2O)12]4+ columns parallel to the c axis vs. the O–H bonds linking the columns within the ab plane. The linear inverse relationship between the low- and high-temperature data from the literature with those collected under high-pressure conditions reveals that the same bonding regime governs the anisotropic expansion and contraction of thaumasite up to ~1.4 GPa and 400 K (HP-HT stability limits of th-I phase).

Published: January 2015

AbstractClay/polymer nanocomposites (CPN) exhibit improved technical properties compared to their microand macro-counterparts. Nevertheless, thermal degradation of CPN may limit the applicability of these hybrid materials. In this paper accelerated ageing (110°C and 150°C) was performed in injection moulded pure polyamide 66 (PA66-S-0 samples) and polyamide 66 reinforced with 5 wt.% sepiolite (PA66-S-5 samples) CPN. Polymer degradation was monitored by the amount of newly formed carbonyl bonds. The carbonyl indices obtained indicate that degradation occurs to a greater extent as the temperature of the ageing process increases. Moreover, the degradation increases with time at the highest treatment temperature (150°C). On the other hand, the occurrence of carbonaceous silicates in the nanocomposite samples at high temperatures yields greater thermal stability of sepiolite/PA66 nanocomposites compared to pure PA66. Furthermore, the sepiolite nanofibres maintain their position in the reticulated semicrystalline structure. In agreement with those results, differential scanning calorimetry and X-ray diffraction analyses show that the motion of the amide groups in the polymer chains are constrained by the well dispersed sepiolite.
Minerals formed by the weathering of sulfides in mines of the Czech part of the Upper Silesian Basin

Published: January 2015

AbstractThis study describes the occurrences of sulfate minerals in mines of the Czech part of the Upper Silesian Basin. This mineralization originates from the oxidation of Fe disulfides contained in the coal matrix and enclosing sediments. The oxidation occurs in the presence of formational brines and chemotrophic bacteria. The brines have a pH between 6.3 and 8.5 and total solute content of up to 300 g/l. They are rich in Na, Ca, K, Mg, Ba and Sr and Cl– is the major anion. The minerals of the pickeringite–halotrichite series with coexisting magnesiocopiapite are formed primarily in drier places and areas where the water is only slightly mineralized. In more humid places where the brines are more concentrated, a diverse assemblage of up to 20 different sulfates are found (e.g. natrojarosite, sideronatrite, metasideronatrite, tamarugite, magnesiocopiapite, bílinite, starkeyite, blödite, rozenite and siderotil). These sulfates are accompanied by halite, sulfur, goethite and a number of phases of uncertain identity, such as sulfates containing Sr and REE. This is an example of mineral paragenesis formed by weathering in a saline evaporite environment, which is extremely rare in Europe but is found in arid regions elsewhere (e.g. in the Atacama Desert in Chile).
Modelling of dissolution–reprecipitation ion-exchange reactions for the development of flame perthite in a suite of sheared alkaline rocks: an example from Chimakurthy, Eastern Ghats, India
Authors: Bhattacharyya Sudip , Sengupta P. 
Published: January 2015

AbstractA suite of sheared syenites occurring along the western margin of the Eastern Ghats Belt, India have developed extensive flame perthite in K-feldspar. Albite flames show large variation in size, shape and abundance. Field, petrographic and chemical evidence suggests complex interplay between differential stress, recycling of K-Na-Ca and supply of Na by infiltration for the development of flame perthite. Partial replacement of pyroxenes, plagioclase and alkali feldspar by amphibole, biotite, nepheline and calcite causes internal recycling of Na-Ca-K in a closed system. Representative compositions of the minerals are used to constrain the model dissolution–reprecipitation ion-exchange reactions involving Na and K either as reactants and/or as products. A substantial proportion of Na+ required for the development of the albite flames, originates from Na metasomatism accompanied by ductile shearing in the feldspathic rocks, providing an ideal open system wherein both the differential stress and Na+ are made available for the development of the flame perthites. This process probably augmented the replacement of K-feldspar grains by flame albite and the K+ released was carried away by the fluid or, possibly, augmented the biotite-forming reactions in the associated quartz-poor syenites and, hence, trigger the Na-K cycle in these rocks.
microRNAs function in CD8+T cell biology

Published: January 2015

Abstract
During an immune response, CD8+T cells can differentiate into multiple types of effector and memory cells that are important components of immune surveillance. However, their dysregulation has been implicated in infection with viruses or intracellular bacteria and tumorigenesis. miRNAs have been identified as crucial regulators of gene expression, and they perform this function by repressing specific target genes at the post-transcriptional level. Most miRNAs expressed in a given cell type serve the function to impede broadly cell-type-inappropriate gene expression and potently deepen a pre-existing differentiation program. It is increasingly recognized that miRNAs directly modulate the concentration of many regulatory proteins that are required for the development of immune cells in the thymus and their responses in the periphery. This review outlines our current understanding of the function of miRNAs in CD8+T cell biology as it impacts expression of protein-coding genes in the context of proper development, infection, as well as oncogenesis. In addition, we conclude with a perspective on future challenges and the clinical relevance of miRNA biology.

Published: January 2015

Purpose We examined whether the survival advantage of androgen-deprivation therapy with radiotherapy (ADT plus RT) relative to ADT alone for men with locally advanced prostate cancer reported in two randomized trials holds in real-world clinical practice and extended the evidence to patients poorly represented in the trials. Methods We conducted nonrandomized effectiveness studies of ADT plus RT versus ADT in three groups of patients diagnosed between 1995 and 2007 and observed through 2009 in the SEER-Medicare data set: (1) the randomized clinical trial (RCT) cohort, which included men age 65 to 75 years and was most consistent with participants in the randomized trials; (2) the elderly cohort, which included men age > 75 years with locally advanced prostate cancer; and (3) the screen-detected cohort, which included men age ≥ 65 years with screen-detected high-risk prostate cancer. We evaluated cause-specific and all-cause mortality using propensity score, instrumental variable (IV), and sensitivity analyses. Results In the RCT cohort, ADT plus RT was associated with reduced cause-specific and all-cause mortality relative to ADT alone (cause-specific propensity score–adjusted hazard ratio [HR], 0.43; 95% CI, 0.37 to 0.49; all-cause propensity score–adjusted HR, 0.63; 95% CI, 0.59 to 0.67). Effectiveness estimates for the RCT cohort were not significantly different from those from randomized trials (P > .1). In the elderly and screen-detected cohorts, ADT plus RT was also associated with reduced cause-specific and all-cause mortality. IV analyses produced estimates similar to those from propensity score–adjusted methods. Conclusion Older men with locally advanced or screen-detected high-risk prostate cancer who receive ADT alone risk decrements in cause-specific and overall survival.
