مستخلص: A hospital bed having foot egress, including a foot section with a pair of foot panels that can pivot upward and be locked into place to provide a support structure for standing and ambulation. Each of the pair of foot section panels can include a grab handle for assistance in standing. The foot end of the frame of the bed includes a retractable crossbar which supports the foot panels, and which can be reversibly retracted towards the middle of the bed frame and beneath the seat section of the bed to provide a clearing at the distal foot end of the bed for the patient to stand and exit the bed safely and efficiently.

الوصف: Purpose: To compare the repair of penetrating corneal incisions in an in vivo rabbit model using a laser-activated thin-film adhesive, sutures, or self-seal. Setting: The University of Sydney, Camperdown, Australia. Design: Animal studies. Methods: Under an operating microscope, 2.0 mm penetrating incisions were created in 162 right eyes. Incisions in one group were repaired with the adhesive, the second group received a single 10-0 nylon suture, and the third group was left to self-seal. Rabbits were killed humanely at predetermined timepoints over 2 weeks, and wound healing was assessed using burst pressure and immunohistological studies. A modified McDonald-Shadduck scoring was used to assess eyes. Results: The mean burst pressure of the adhesive group was significantly higher than the sutured or self-sealed groups at all timepoints within the first 72 hours. At 0 hour, the burst pressure was 98.0 (±17.0) mm Hg, 30.6 (±2.1) mm Hg, and 3.8 (±0.6) mm Hg ( P < .00001) for adhesive-treated (n = 5), sutured (n = 5), and self-sealed wounds (n = 5), respectively. These increased to 229.0 (±53.7) mm Hg, 12.4 (±2.9) mm Hg, and 27.3 (±4.0) mm Hg ( P = .0011) at 72 hours. The modified McDonald-Shadduck score was significantly higher for eyes repaired using the adhesive than those sutured or left to self-seal for the first 72 hours. On histology and immunofluorescence, adhesive treatment demonstrated better wound approximation and higher myofibroblastic activation than the other groups. Conclusions: The adhesive was efficacious in sealing penetrating corneal incisions and tolerated higher burst pressures than sutures or self-seal. The adhesive was biocompatible in rabbits, and incisions demonstrated a rapid gain in wound strength that sustained over the study period.

الوصف: Poly(β-hydroxybutyrate), (PHB), is a biologically produced, biodegradable thennoplastic with commercial potential. In this work the qualitative and quantitative investigations of the structure and degradation of a previously unstudied, novel, fibrous form of PHB, were completed. This gel-spun PHB fibrous matrix, PHB(FM), which has a similar appearance to cotton wool, possesses a relatively complex structure which combines a large volume with a low mass and has potential for use as a wound scaffolding device. As a result of the intrinsic problems presented by this novel structure, a new experimental procedure was developed to analyze the degradation of the PHB to its monomer hydroxybutyric acid, (HBA). This procedure was used in an accelerated degradation model which accurately monitored the degradation of the undegraded and degraded fractions of a fibrous matrix and the degradation of its PHB component. The in vitro degradation mechanism was also monitored using phase contrast and scanning electron microscopy, differential scanning calorimetry, fibre diameter distributions and Fourier infra-red photoacoustic spectroscopy. The accelerated degradation model was used to predict the degradation of the samples in the physiological model and this provided a clearer picture as to the samples potential biodegradation as medical implantation devices. The degradation of the matrices was characterized by an initial penetration of the degradative medium and weakening of the fibre integrity due to cleavage of the ester linkages, this then led to the physical collapse of the fibres which increased the surface area to volume ratio of the sample and facilitated its degradation. Degradation in the later stages was reduced due to the experimental kinetics, compaction and degradation resistant material, most probably the highly crystalline regions of the PHB. The in vitro degradation of the PHB(FM) was influenced by blending with various polysaccharides, copolymerizing with poly(~-hydroxyvalerate), (PHV), and changes to the manufacturing process. The degradation was also detennined to be faster than that of conventional melt processed PHB based samples. It was concluded that the material factors such as processing, sample size and shape affected the degradation of PHB based samples with the major factor of sample surface area to volume ratio being of paramount importance in determining the degradation of a sample.

مستخلص: Purpose: We assess the effect of consumer-directed care on the emotional, physical, and financial well-being of the primary informal caregivers of the Medicaid beneficiaries who voluntarily joined Arkansas's Cash and Counseling demonstration. Design and Methods: The demonstration randomly assigned beneficiaries to a program in which they could direct their own disability-related supportive services (the treatment group) or rely on traditional agency services (the control group). We constructed outcome measures from telephone interviews with 1,433 caregivers who provided beneficiaries with the most unpaid assistance at baseline, and we used multivariate regression models to estimate program effects. Interviews occurred between February 2000 and April 2002, 10 months after beneficiaries' random assignment. Results: At follow-up, treatment group caregivers provided fewer hours of assistance than did their control group counterparts, on average, and they reported better emotional, physical, and financial well-being. Implications: Permitting interested Medicaid beneficiaries to direct their own in-home supportive services reduces burden on informal care givers, which may help reduce beneficiaries' nursing home use.

مستخلص: The invention provides a bioadhesive composition comprising a polysaccharide and an energy converter, wherein the energy converter is activated by non-UV light. The composition may be prepared by dissolving the polysaccharide and the energy converter in an aqueous acidic solution. The composition, in the form of a film or a gel, may be used for repairing a discontinuity in an area of tissue or for joining tissue.
