The results of allogeneic hematopoietic cell transplantation (alloHCT) may be influenced by smart donor selection. Today, insights from registry studies and translational science can be used to select an optimal donor. In recent work, we investigated whether young unrelated donors (UD) provide a benefit for older patients with myeloid malignancies compared to HLA-identical sibling donors (MSD). In total, we analyzed data from 3460 patients. With multivariable adjustment event-free survival (EFS) (HR 0.86, p = 0.003), overall survival (HR 0.82, p < 0.001), and risk of relapse (HR 0.84, p = 0.018) were significantly better for HLA-compatible UD compared to MSD. No survival advantage was found for UD with unfavorable sex or CMV constellation. In a meta-analysis on 9905 patients with myeloid malignancies, including ours, we found reduced risk of relapse (pooled HR 0.78, p = 0.006) and better EFS (pooled HR 0.89, p < 0.001) for young matched UD versus MSD. In this seminar, we will review our results and interpret their impact in the context of current literature on donor selection for HLA-matched alloHCT.

To assess short term relapse and disability risk after switching from fingolimod (FTY) to ocrelizumab (OCR) or cladribine (CLAD) in patients with relapsing-remitting multiple sclerosis (RRMS)

Learning the proper steps for organizing a failure investigation ensures success. Failure investigations cross company functional boundaries and are an integral component of any design or manufacturing business operation. Well-organized and professionally conducted investigations are essential for solving manufacturing problems and assisting in redesigns. This book outlines a proven systematic approach to failure investigation. It explains the relationship between various failure sources (corrosion, for example) and the organization and conduct of the investigation. It provides a learning platform for engineers from all disciplines: materials, design, manufacturing, quality, and management. The examples in this book focus on the definition of and requirements for a professionally performed failure analysis of a physical object or structure. However, many of the concepts have much greater utility than for investigating the failure of physical objects. For example, the book provides guidance in areas such as learning how to define objectives, negotiating the scope of investigation, examining the physical evidence, and applying general problem-solving techniques.

Prameha has been a global problem is well described in the ancient Indian classics life the Vedas and the Ayurvedic works which ensued the Vedic period . Prameha is a disease, manifesting in one of the tri-marma namely basti .The aetiopathogenesis of pramehas as described by the Ayurvedic authors with a glance to the therapeutic measures is also included in the study.In the present era, many people are suffering from this disease and is often considered as the silent killer. This fact itself triggered the need of review of this disease.Prediabetes means a ‘pre diagnosis of diabetes’. In real sense this is an intermediate state of hyperglycemia that gives you a chance to wake up and combat the dreadful menace untowardly knocking the door of your life. Modern sedentary life style may be one of the basic reasons of this pathological entity. So, understanding its pace with which it is growing all over the world WHO also have declared its moto for this year as ‘Stop Diabetes’ mission. Near about 471 million peoples across the globe are suffering from this ‘Prediabetes’ and unfortunately, Prediabetes is an intermediate state of hyperglycemia where the glycemic level is above normal but below the Diabetic glycemic threshold level. Thus, Prediabetes is a state of high risk for developing Diabetes with 5 to 10% cases converting to Diabetes per annum. The appropriate changes in the life style can definitely reduce the severity of the risk factors and help to overcome the debacle.

BackgroundThe management of patients with rheumatologic diseases (RDs) involves a complex interaction between different parties such as patients, physicians, pharmacists. The development of biologic therapies has created a more complex decision-making process to select the treatment option for patients. To optimize the appropriateness of the decisions, it is necessary to be informed and aware of the preferences of the interested parties.ObjectivesTo estimate preferences of relevant treatment characteristics with biological agents valued by the different subjects involved in the management of patients with rheumatic diseases.MethodsWe involved patients with RDs, rheumatologists, nurses and pharmacists with experience in the treatment with/provision of biological drugs of these patients. Through a Discrete-Choice-Experiment, the participants valued 16 possible scenarios in which pairs of similarly effective treatments were described with 6 characteristics including 2–4 possible levels each: (1) frequency of administration; (2) mode and place of administration; (3) hospitality, service, efficiency and courtesy of health personnel; (4) frequency of reactions at the site of drug administration; (5) generalized undesired/allergic reactions; (6) additional cost: since the Italian NHS pays treatment costs, we included possible additional cost as monthly healthcare taxes for all the citizens, to make available the treatment to all target patients. relative importance of each characteristic was estimated through a random-effects conditional logistic regression model.Results513 patients, 110 rheumatologists, 51 nurses and 46 pharmacists from 30 centres through Italy participated. Characteristics (3), (4) and (6) were the most important for every subgroup, while (1) was the least important for patients and rheumatologists, (2) the least important for the pharmacists, (2) and (5) the least important for the nurses. The four subgroups were consistent in preferences towards the specified levels of characteristics (1) and (3) to (6). However, as for characteristic (2), pharmacists preferred autonomous subcutaneous injection with syringe, nurses preferred assisted infusion at an infusional center close to patient's place, patients and rheumatologists preferred autonomous subcutaneous injection with pen.ConclusionsDifferent subjects show different preferences for some treatment characteristics, which together with pure clinical aspects can play an important role in the choice and consequent success of treatments.Disclosure of InterestP.

We present a new evaluation of the negatively charged pion mass based on the simultaneous spec-troscopy of pionic nitrogen and muonic oxygen transitions using a gaseous target composed by a N 2 /O 2 mixture at 1.4 bar. We present the experimental setup and the methods for deriving the pion mass value from the spatial separation from the 5g -- 4 f $\pi$N transition line and the 5g -- 4 f $\mu$O transition line used as reference. Moreover, we discuss the importance to use dilute targets in order to minimize the influence of additional spectral lines from the presence of remaining electrons during the radiative emission. The occurrence of possible satellite lines is investigated via hypothesis testing methods using the Bayes factor.

In the wet-texturing process, a smaller etch depth of 8 µm was established on each side of the thin silicon wafer. Formation of a very small size (1–3 µm) pyramidal structure was confirmed on a thin c-Si surface through the use of SEM micrographs. For this silicon surface with small pyramidal structures, a surface reflectance of 15.14% was observed. Saw damage removal was employed for the second and the third sets of silicon wafers in a NaOH (8 wt%) solution, and the wafers were then textured in a mixture of NaOH (1.5 wt%), de-ionized water and Isopropyl alcohol (IPA, 6–8 wt%) at 80 °C for 18 min and 24 min, respectively. In this process, the scraped depths were 16 and 26 µm on each side of the second and the third sets of silicon wafers, and the pyramidal sizes were 4–9 µm and 9–12 µm respectively. We found that the reflectances of these sets of wafers were 14.98% and 14.78%, respectively. Our novel approach of ultrasonic cleaning, hot de-ionized water treatment, and texturing for thin c-Si wafers yielded small-sized (1–3 µm) uniform pyramidal structure that were stable and suitable for metalized screen printing. Even though the reflectance was high for the first set of wafers the illuminated current-voltage (LIV) measurements confirmed the wafers’ superiority over the conventional textured c-Si solar cells in terms of the open-circuit voltage and the fill factor. The small-size pyramidal-structured thin single-crystalline silicon solar cells showed a 17.9% efficiency. Since no NaOH solution was used for saw damage removal in the first set of silicon wafers, the production cost for commercial production of large-area single-crystalline silicon solar cells was reduced by nearly 20%.

Some implants have approximately a lifetime of 15 years. The femoral stem, for example, should be made of 316L/316LN stainless steel. Fretting corrosion, friction under small displacements, should occur during human gait, due to repeated loadings and un-loadings, between stainless steel and bone for instance. Some experimental investigations of fretting corrosion have been practiced. As well known, metallic alloys and especially stainless steels are covered with a passive film that prevents from the corrosion and degradation. This passive layer of few nanometers, at ambient temperature, is the key of our civilization according to some authors. This work is dedicated to predict the passive layer thicknesses of stainless steel under fretting corrosion with a specific emphasis on the role of proteins. The model is based on the Point Defect Model (micro scale) and an update of the model on the friction process (micro-macro scale). Genetic algorithm was used for finding solution of the problem. The major results are, as expected from experimental results, albumin prevents from degradation at the lowest concentration of chlorides; an incubation time is necessary for degrading the passive film; under fretting corrosion and high concentration of chlorides the passive behavior is annihilated. Les implants orthop\'ediques de hanche ont une dur\'ee de vie d'environ 15 ans. Par exemple, la tige f\'emorale d'un tel implant peut \^etre r\'ealis\'ee en acier inoxydable 316L ou 316LN. Le fretting corrosion, frottement sous petits d\'eplacements, peut se produire pendant la marche humaine en raison des chargements r\'ep\'et\'es entre le m\'etal de la proth\`ese et l'os. Plusieurs investigations exp\'erimentales du fretting corrosion ont \'et\'e entreprises. Cette couche passive de quelques nanom\`etres, \`a temp\'erature ambiante, est le point clef sur lequel repose le d\'eveloppement de notre civilisation, selon certains auteurs. Ce travail vise \`a pr\'edire les \'epaisseurs de cette couche passive de l'acier inoxydable soumis au fretting corrosion, avec une attention sp\'ecifique sur le r\^ole des prot\'eines. Le mod\`ele utilis\'e est bas\'e sur le Point Defect Model, PDM (\`a une \'echelle microscopique) et une am\'elioration de ce mod\`ele en prenant en compte le processus de frottement sous petits d\'ebattements. L'algorithme g\'en\'etique a \'et\'e utilis\'e pour optimiser la convergence du probl\`eme. Les r\'esultats les plus importants sont, comme d\'emontr\'e avec les essais exp\'erimentaux, que l'albumine, la prot\'eine \'etudi\'ee, emp\^eche les d\'egradations de l'acier inoxydable aux plus faibles concentrations d'ions chlorure ; ensuite, aux plus fortes concentrations de chlorures, un temps d'incubation est n\'ecessaire pour d\'etruire le film passif.
