Scaffold Case

Tissue engineering is an emerging interdisciplinary field that uses principles from engineering, biology and chemistry in an effort towards tissue regeneration. The main draw of tissue engineering is the regeneration of a patient’s own tissues and organs free from low biofunctionality and poor biocompatibility and serious immune rejection. As medical care continues to improve and life expectancy continues to grow, organ shortages become more problematic.(Manufacturing living things) According to organdonor.gov, a patient is added to the waiting list every 10 minutes and an average of 18 people die everyday waiting for an organ donation. The “nirvana” of tissue engineering is to replace the need for organ donation altogether. This could be achieved using scaffolding from

Describe the series of events that occur in skin, which is healing with the help of a skin graft?

Barrett (2009) concurs that, the management of wound required dressing that can maintain a moist environment, absorbs exudates as well as remain in situ over number of days.

Skin repair is an important physiological process which is essential for homeostasis, restoring barrier function and preventing infection (Martin, 2009; Boateng and Catanzano, 2015). Wound healing is defined as a complex, dynamic and the specific biological process associated with the phenomena of tissue regeneration and growth (Mazumder et al., 2016). Regeneration can be defined as a tissue that significantly damaged either completely or partially removed and tissue's original function and cell types must be functional and structurally restored (Mazumder et al., 2016). The process of healing comprises a cytokine, blood cells, extracellular matrix and growth factor (Joao De Masi et al., 2016). The growth factor is a protein that activates and

The goal to treat an ulcer in a diabetic patient is to heal the wound faster to prevent infection, pressure has to be take off the area by “offloading” the foot, remove dead tissue by the process of debridement, apply to dress per doctors order, and focus on managing the patient’s blood sugar effectively to promote healing. In addition, to prevent infection, the patient must keep the dressing clean, cleanse the wound daily and change the bandage and dressing, the patient must also avoid walking on barefoot.

The recommendations for change to practice at the level of the provider would include first treating the underlying problem that Mrs. Smith was admitted for. According to the literature, a progressively worsening diabetic foot ulcer involves implementing a multitude of strategies to prevent amputation of the limb. This allow for decreased rates in mortality and can increase quality of life. Adequate wound management such as debridement, and offloading techniques should be instilled. Furthermore, education by the provider would be of critical importance for Mrs. Smith in terms of consistent foot care and management of her disease process (Yazdanpanah, Nasiri, & Adarvishi, 2015). Due

Integra is a synthetic wound dressing frequently used to treat burn wounds (Figure 5). It is a bilayer composed of bovine tendon collagen glycosaminoglycan (chondroitin-6-sulphate) cross-linked to it, onto which a silicone (synthetic polysiloxane polymer) membrane is sealed to the upper surface to act as a protective temporary epidermis. The silicone layer is applied as a liquid monomer; curing occurs on the surface of the collagen at room temperature. It serves to control moisture loss from the wound. Water flux across this silicone membrane is the same as that across normal epidermis. The collagen-GAG matrix contains pores ranging from 70 to 200 µm that are invaded by host fibroblasts upon application to an excised wound bed. The pore size was carefully designed by adjusting the collagen-GAG mixture. In GAG-free collagen, the resulting structure was more closed than in collagen-GAG matrices. Smaller pores can delay, or even prevent, biointegration, whereas larger pores would provide an insufficient attachment area for invading host cells. Freeze-drying procedures followed by slow sublimation are used to control pore size too. The degradation rate of 30 days of the collagen-GAG sponge is controlled by glutaraldehyde-induced cross-links. The polypeptide collagen is used for its low levels of antigenicity (it has minimal rejection potential) and because it exerts a hemostatic effect on vascular wounds. Collagen is already found in skin. It is degraded by collagenase deposited

Based on progress report dated 06/22/15 by Dr. Wrotslavsky, the patient is 3 weeks status post skin flap and skin graft right plantar foot. Patient states he cannot reach his foot and do his own dressing changes. Patient has a right foot ulcer. He states Methicillin-resistant Staphylococcus

Patients at Long Term Care Facilities are generally debilitated and elderly people who have incontinence problems. Incontinence makes treating pressure ulcers very difficult because it alters tissue tolerance and reapplying products becomes very costly. Usually negative pressure wound therapy (NPWT) is used to treat pressure ulcers but it is also very costly and does not match with some wound locations. Collagen plays a vital role in the wound healing process by creating a framework for the adhesion, movement, and production of new cells. This study determined the effects and uses of Type 1 formulated collagen on granulation tissue formation and reepithreelialization in chronic pressure ulcers.

The recommendations for change to practice at the level of the provider would include first treating the underlying problem that Mrs. Smith was admitted for. According to the literature, a progressively worsening diabetic foot ulcer requires implementing a multitude of strategies to prevent amputation of the limb. Adequate wound management, including debridement if required, and offloading techniques should be instilled for Mrs. Smith.

There are two methods of cloning organs. One is by injecting a growth factor into the wound site, causing the patient's own cells to migrate and regenerate. The other method is to harvest donor cells and pack them into a three-dimensional polymer scaffold, which is molded into the desired shape. These cells replicate and then can be transplanted into a recipient. The polymer breaks down as the cells form into the shape desired. These organs are called neo-organs. While this may sound like something straight out of a science fiction film, like Dolly, neo-organs are already a reality. All over the United States, grown skin is being used to treat everything from burn victims to skin cancer patients. Also, machines containing cloned liver cells are being used to filter blood until a transplant can be found. Cartilage, because of it's relatively simple structure, seems likely to be the next step. Larger organs will take

As today’s technology is changing, some of the most major effects of it are superior advances in the medical field. One advance in the medical field is tissue engineering. It is being developed for use in regenerative medicine and soon to be in wider use for other treatments. Tissue engineering’s goal for the future is for the medicine to be able to stimulate other cells around the damage area of the body to get them to grow and produce living tissue (Sciencedaily). Another medical advancement is the monitoring systems and how hospitals can better track for problems and signs of an emergency. This can also help the surgeons decide how to stitch up a patient for best recovery time (Sciencedaily). As technology keeps progressing, another medical advancement is the way surgeons are doing operations. Today, for complex surgeries, surgeons now will get help from the use of a robot for accurate procedures; this will help with the size of the incision and keep the recovery time shorter than during standard surgery.

The management of diabetic foot ulcers remains a major therapeutic challenge, which implies an urgent need to review strategies and treatments in order to achieve the goals and reduce the burden of care in an efficient and cost-effective way. Questions remain as to which types of intervention, technology, and dressing are suitable to promote healing, and whether all therapies are necessary and cost-effective as adjunctive therapies. Prevention of diabetic foot ulceration is critical in order to reduce the associated high morbidity and mortality rates, and the danger of amputation. It is essential to identify the “foot at risk,” through careful inspection and physical examination of the foot followed by neuropathy and vascular tests. Regular

he foot of a diabetic patient has the potential risk of developing complications such as infection, ulceration, and/or destruction of deep tissues associated with neurologic abnormalities, various degrees of peripheral vascular disease, and/or metabolic complications of diabetes in the lower limb. The lifetime risk of a diabetic individual having a foot ulcer could be as high as 25%. As indicated by the International Diabetic Federation in 2005, 85% of diabetes-related amputations in the lower extremity are preceded by a foot ulcer. Diabetic foot ulcers result from the simultaneous action of various contributing causes. The main causes are said to be peripheral neuropathy and ischemia from peripheral vascular disease. The gold standard for

The combination of limb progenitor cells and growth factors/signaling pathways are both needed for normal limb regeneration. The fibrin patch method employed to deliver the growth factors and progenitor cell plays a role in normal limb regeneration. The fibrin patch was able to deliver cells and the slow release beads containing growth factors in a way that promoted cell survival and migration in contrast to a direct injection
