TL;DR: This integrated mutational and cytogenetic model independently predicted survival, improved CLL prognostication accuracy compared with FISH karyotype, and was externally validated in an independent CLL cohort.

TL;DR: It is concluded that JAK2 617V>F homozygosity identifies PV or ET patients with a more symptomatic myeloproliferative disorder and is associated with a higher risk of major cardiovascular events in patients with ET.

TL;DR: Similar binding repertoires for the LG modules of three basement membrane proteins involved in cell–matrix interactions and supramolecular assembly are demonstrated.
Abstract: The C‐terminal G domain of the mouse laminin α2 chain consists of five lamin‐type G domain (LG) modules (α2LG1 to α2LG5) and was obtained as several recombinant fragments, corresponding to either individual modules or the tandem arrays α2LG1‐3 and α2LG4‐5. These fragments were compared with similar modules from the laminin α1 chain and from the C–terminal region of perlecan (PGV) in several binding studies. Major heparin‐binding sites were located on the two tandem fragments and the individual α2LG1, α2LG3 and α2LG5 modules. The binding epitope on α2LG5 could be localized to a cluster of lysines by site‐directed mutagenesis. In the α1 chain, however, strong heparin binding was found on α1LG4 and not on α1LG5. Binding to sulfatides correlated to heparin binding in most but not all cases. Fragments α2LG1–3 and α2LG4‐5 also bound to fibulin‐1, fibulin‐2 and nidogen‐2 with K d = 13–150 nM. Both tandem fragments, but not the individual modules, bound strongly to α‐dystroglycan and this interaction was abolished by EDTA but not by high concentrations of heparin and NaCl. The binding of perlecan fragment PGV to α‐dystroglycan was even stronger and was also not sensitive to heparin. This demonstrated similar binding repertoires for the LG modules of three basement membrane proteins involved in cell–matrix interactions and supramolecular assembly.

TL;DR: The aim of this study was to review the methods to assess muscle mass and to reach consensus on the development of a reference standard for measuring lean body mass.
Abstract: BACKGROUND: All proposed definitions of sarcopenia include the measurement of muscle mass, but the techniques and threshold values used vary. Indeed, the literature does not establish consensus on the best technique for measuring lean body mass. Thus, the objective measurement of sarcopenia is hampered by limitations intrinsic to assessment tools. The aim of this study was to review the methods to assess muscle mass and to reach consensus on the development of a reference standard. METHODS: Literature reviews were performed by members of the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis working group on frailty and sarcopenia. Face-to-face meetings were organized for the whole group to make amendments and discuss further recommendations. RESULTS: A wide range of techniques can be used to assess muscle mass. Cost, availability, and ease of use can determine whether the techniques are better suited to clinical practice or are more useful for research. No one technique subserves all requirements but dual energy X-ray absorptiometry could be considered as a reference standard (but not a gold standard) for measuring muscle lean body mass. CONCLUSIONS: Based on the feasibility, accuracy, safety, and low cost, dual energy X-ray absorptiometry can be considered as the reference standard for measuring muscle mass.

TL;DR: A tradeoff between the optimal voltage and the severity of side effects made it possible to control parkinsonian signs effectively, and preliminary data indicate that functional inactivation of the STN may reduce the requirement for dopaminergic therapy in PD.
Abstract: Objective: To reduce antiparkinsonian medication in parkinsonian patients with bilateral high frequency subthalamic nucleus (STN) stimulation. Background: Parkinsonian syndromes are characterized by hyperactivity of the STN. Preliminary data indicate that functional inactivation of the STN may reduce the requirement for dopaminergic therapy in PD. Methods: Bilateral quadripolar leads were implanted stereotactically in the STN of seven patients with advanced PD (mean age, 57.4 years; mean disease duration, 15.4 years). High-frequency stimulation was applied for 24 hours a day. Following implantation, antiparkinsonian medication was reduced to the minimum possible and stimulation was gradually increased. The patients were evaluated in the practically defined “off” and “on” conditions using the Unified Parkinson’s Disease Rating Scale (UPDRS) and the Schwab & England scale. The average follow-up was 16.3 ± 7.6 months. A battery of neuropsychological tests was applied before and 9 months after the implant. Results: Parkinsonian features improved in all patients—the greatest change seen in rigidity, then tremor, followed by bradykinesia. Compared with the presurgical condition, off-drug UPDRS motor scores improved by 41.9% on the last visit ( p = 0.0002), UPDRS activities of daily living (ADL) scores improved by 52.2% ( p = 0.0002), and the Schwab & England scale score improved by 213% ( p = 0.0002). The levodopa-equivalent daily dose was reduced by 65%. Night sleep improved in all patients due to increased mobility at night, and in five patients insomnia was resolved. All patients gained weight after surgery and their appetite increased. The mean weight gain at the last follow-up was 13% compared with before surgery. During the last visit, the stimulation amplitude was 2.9 ± 0.5 V and the total energy delivered per patient averaged 2.7 ± 1.4 W × 10 −6 . The results of patient self-assessment scales indicated a marked improvement in five patients and a moderate improvement in the other two. The neuropsychological data showed no changes. Side effects were mild and tolerable. In all cases, a tradeoff between the optimal voltage and the severity of side effects made it possible to control parkinsonian signs effectively. The most marked side effects directly related to STN stimulation consisted of ballistic or choreic dyskinesias of the neck and the limbs elicited by contralateral STN stimulation above a given threshold voltage, which varied depending on the individual. Conclusions: Parkinsonian signs can be controlled by bilateral high-frequency STN stimulation. The procedure is well tolerated. On-state dyskinesias were greatly reduced, probably due to the reduction of total antiparkinsonian medication. Bilateral high-frequency STN stimulation compensated for drug reduction and elicited dyskinesias, which differ from those observed following dopaminergic medication. ADL improved significantly, suggesting that some motor tasks performed during everyday chores, and that are not taken into account in the UPDRS motor score, also improved.
