This paper describes a pilot multidisciplinary computer-based therapy tool for motor and language rehabilitation following brain injury. The functional connectivity and structural proximity of elements of the language and motor systems result in frequent co-morbidity post brain injury. Although rehabilitation services are becoming increasingly multidisciplinary and "integrated", treatment for language and motor functions often occurs in isolation. Thus, behavioural therapies which promote neural reorganisation and neuronal regrowth do not reflect the high intersystem connectivity of the neurologically intact brain. As such, there is a pressing need for rehabilitation tools which better reflect and target the impaired cognitive networks. This project uses the Kinect sensor to develop an integrated motor and language rehabilitation therapy tool, capable of providing cost-effective, long-term, high dosage rehabilitation in the home setting. © 2015 ACM.

Background and objectives: Ketamine S(+) is important in pain modulation in surgical patients. The objective of the present study was to evaluate the relationship between the levels of sedation produced by low doses of ketamine S(+), as well as encephalographic variables: BIS, SEF 95%, pEMG, suppression rate, and presence of burst-suppression. Methods: Thirty patients of both sexes, aged 25-50 years, were randomized into three groups. Group G1 (10) received intravenous ketamine S(+) 0.050 mg,kg-1; group G2 (10) intravenous ketamine S(+) 0.125 mg.kg-1; and group G3 (10) intravenous ketamine S(+) 0.250 mg.kg-1. All patients received 0.08 mg.kg-1 of intravenous midazolam 10 minutes before administration of ketamine S(+). In each group, two moments were evaluated: M1, before ketamine S(+) administration; and M2, after ketamine S(+) administration. Sedation levels and encephalographic variables: BIS, SEF 95%, pEMG, suppression rate, and the presence of burst-suppression were evaluated in all patients before and after ketamine S(+) administration. ANOVA was used for repeated measurements and the p-value was adjusted for multiple comparisons by Tukey's test. Results: A decrease in alertness-sedation scale scores was observed in all three groups in moment M2. Electroencephalographic variables showed significant variation in all three groups when moments M1 and M2 were compared, both in pEMG and BIS (p < 0.05). Conclusions: Sedation levels showed significant correlation with the increase in ketamine S(+) dosage. However, increased BIS levels may have reflected increased pEMG induced by ketamine S(+). © 2011 Elsevier Editora Ltda.

Synthesis and remodeling of the lung matrix is necessary for primary and compensatory lung growth. Because cyclic negative force is applied to developing lung tissue during the respiratory cycle, we hypothesized that stretch is a critical regulator of lung matrix remodeling. By using quantitative image analysis of whole-lung and whole-lobe elastin in situ zymography images, we demonstrated that elastase activity increased twofold during the alveolar stage of postnatal lung morphogenesis in the mouse. Remodeling was restricted to alveolar walls and ducts and was nearly absent in dense elastin band structures. In the mouse pneumonectomy model of compensatory lung growth, elastase activity increased threefold, peaking at 14 days postpneumonectomy and was higher in the accessory lobe compared with other lobes. Remodeling during normal development and during compensatory lung growth was different with increased major airway and pulmonary arterial remodeling during development but not regeneration, and with homogenous remodeling throughout the parenchyma during development, but increased remodeling only in subpleural regions during compensatory lung growth. Left lung wax plombage prevented increased lung elastin during compensatory lung growth. To test whether the adult lung retains an innate capacity to remodel elastin, we developed a confocal microscope-compatible stretching device. In ex vivo adult mouse lung sections, lung elastase activity increased exponentially with strain and in peripheral regions of lung more than in central regions. Our study demonstrates that lung elastase activity is stretch-dependent and supports a model in which externally applied forces influence the composition, structure, and function of the matrix during periods of alveolar septation.

A good idea does not inevitably lead to successful innovation; it needs additional "drivers" and coherent activity of a specialized team. The initial idea needs proof-of-concept and prototype testing. Alongside, market review must anticipate future need and competitors, and ensure that no current patents are infringed. The likelihood that reimbursement will be secured and that health systems will "adopt" the device has to be considered. Intellectual property (IP) protection is needed to maintain sole rights to exploit the core concept. Non-disclosure agreements (NDA) should be put in place, and commercial considerations should be remembered before any disclosure in the public domain, including publications. Prospective business partners will review the concept from many perspectives, including stage of device development, effective IP protection, any clinical trial evidence, and whether the device aligns with their business strategy. Royalties arising from sales of a marketed device are distributed to all parties contributing to its development; the party bearing the greater financial burden of developing the final product will gain the greater share of royalties. The innovator's employer will have a call on proceeds if the idea arose in the course of employment. All stages of development require fastidious documentation to meet requirements of the regulatory authorities responsible for permitting use in patients. Specific regulatory requirements depend on which region(s) of the world the device will be marketed in. This review explains all stages of the innovation pathway from concept to adoption, giving practical advice and signposting expertise relevant to each stage. Copyright © 2011 Wiley Periodicals, Inc.

The hospital-wide pooling and sharing of certain types of medical equipment can lead to both significant improvements in patient safety and financial advantages when compared with a department or ward-level equipment ownership system. In September 2003, a Medical Equipment Loan Service (MELS) was established, focusing initially on infusion pumps. The aims and expected benefits included; improving availability of equipment for both patients and clinical users, managing and reducing clinical risk, reducing equipment diversity, improving equipment management and reducing the overall cost of equipment provision. A user survey was carried out in 2005 and repeated in 2011. The results showed wide and continued satisfaction with the service. The process and difficulties of establishing the service and its development to include additional types of equipment are described. The benefits of managing medical equipment which is in widespread general use, through a MELS as part of a Clinical Engineering Department, are presented. © 2015 © 2015 Informa UK Ltd.
