The Advanced GAmma Tracking Array (AGATA) is a European project to develop and operate the next generation gamma-ray spectrometer. AGATA is based on the technique of gamma-ray energy tracking in electrically segmented high-purity germanium crystals. This technique requires the accurate determination of the energy, time and position of every interaction as a gamma ray deposits its energy within the detector volume. Reconstruction of the full interaction path results in a detector with very high efficiency and excellent spectral response. The realisation of gamma-ray tracking and AGATA is a result of many technical advances. These include the development of encapsulated highly segmented germanium detectors assembled in a triple cluster detector cryostat, an electronics system with fast digital sampling and a data acquisition system to process the data at a high rate. The full characterisation of the crystals was measured and compared with detector-response simulations. This enabled pulse-shape analysis algorithms, to extract energy, time and position, to be employed. In addition, tracking algorithms for event reconstruction were developed. The first phase of AGATA is now complete and operational in its first physics campaign. In the future AGATA will be moved between laboratories in Europe and operated in a series of campaigns to take advantage of the different beams and facilities available to maximise its science output. The paper reviews all the achievements made in the AGATA project including all the necessary infrastructure to operate and support the spectrometer. (C) 2011 Elsevier B.V.

Exercising with the Pilates method may be a beneficial treatment to improve balance and decrease the number of falls. To ascertain this, our search in 7 databases included 15 randomized controlled trials in which Pilates was the primary intervention. Participants were over 60 years of age; the outcomes were related to balance and falls. The Cochrane tool and PEDro scale were used to assess risk of bias and quality of individual studies. Current evidence supported the view that exercising with the Pilates method improves the balance of older adults with a high practical effect in terms of the dynamic (SMD=0.75[0.17;1.32]), static (SMD=1.33[0.53;2.13]) and overall balance (SMD=0.96[0.00;1.91]). Pilates also produced greater improvements with a moderate effect in terms of the dynamic (SMD=0.37[-0.36;1.11]) and overall balance (SMD=0.58[0.19;0.96]) compared to other training approaches oriented to the same end. Literature evaluating the effects on falls is scarce, and results were not conclusive.
Objective: To assess the effects of preoperative balance training on the early postoperative balance and functional outcomes after total knee replacement surgery and to test whether an outpatient intervention may be as effective as a domiciliary intervention. Design: This is a three-arm randomized controlled trial. Setting: University hospital. Subjects: Eighty-six individuals were recruited. Seventy-seven were analysed, aged 72.1 (SD 7.6) years, of which 68% were women. Outcome measures: Overall state of balance, as measured with the Berg Balance Scale, and patient-perceived functionality, as measured with the Knee Injury and Osteoarthritis Outcome Score Function in Activities in Daily Living (KOOS-ADL) questionnaire, were the primary outcomes. Secondary assessments targeted knee function, balance and mobility, quality of life, and self-reported outcomes. The primary end-point was six weeks after surgery. Intervention: The hospital group implemented a four-week preoperative outpatient balance-oriented intervention. The home group implemented similar training, but this was domiciliary. The control group was instructed to keep performing their normal activities. Results: Home and hospital groups presented a moderate effect against the control group ( dhospital-control = 0.54; dhome-control = 0.63), both being similarly effective in improving the overall state of balance at six weeks after surgery ( P = 0.013). KOOS-ADL scores showed no between-group differences and a small effect size ( d < 0.5; P = 0.937). Secondary assessments suggested non-significant between-group differences. Conclusion: Preoperative balance training, conducted either as domiciliary or as an outpatient, is an effective approach to enhance early postoperative balance outcome but not the perceived functionality of individuals undergoing total knee replacement.
