Active clinical trials for "Atrophy"

The objective of the study is to evaluate histomorphometrically the healing at implants installed with standard or very low insertion torque values.

This study is a biomarker evaluation study in patients with geographic atrophy secondary to age-related macular degeneration (AMD). The study evaluates microperimetry (fundus-controlled perimetry) and optical coherence tomography imaging for assessing changes in retinal sensitivity and anatomy over time.

It is believed that the average person with an eighty year old life span will walk the distance of the world twice in their lifetime. The foot is comprised of a specialized fat pad to provide shock absorption and protection against breakdown. With all the walking humans do however, foot fat pad breakdown is inevitable. Trauma to the foot is compounded in the diabetic patients due to many reasons: loss of protective sensation secondary to neuropathy, reduced skin hydration, decreased soft tissue elasticity, elevated blood sugars and increased body weight to name a few. Increased foot pressure and decreased fat pad protection are the main contributing factors to callus formation, foot pain and ulcer formation. Fat grafting is a cosmetic and reconstructive procedure that is used sometimes to help improve one's soft tissue thickness, shape and integrity. Autologous fat transplantation is a procedure using a patient's own fat that is taken by a small liposuction tube, from areas with a substantial amount of fat ( i.e. abdomen or thighs) and then transferred into the fat atrophied (decreased or worn out) area (in this case, the foot). The investigators are performing this research in an effort to decrease foot pressure during activity and to increase the soft tissue thickness of the sole of the foot during one's lifetime. Ultimately this could help reduce foot pain, callus formation and even ulcer formation. The goal of this research is to see whether fat grafting will help decrease the prevalence of the aforementioned foot complications. The investigators hope that by using one's own fat tissue, he or she may have a longer duration of relief than by using other methods. This is a randomized, cross-over designed study. Randomized means that patients will be enrolled by chance (like the flip of a coin) to one of two groups for the first part of the study. Cross-over means that, after the first part of the study or at one year, patients will move into the opposite group. One group will receive the fat grafting procedure with one year follow up (year A pathway) and the other will receive standard of care treatment from the patient's primary podiatrist during the first year (year B pathway). After the first year, patients will switch to the opposite year pathway for the next 12 months. Participation in this study will last approximately 24-26 months.

This is a prospective, multi-site trial to be conducted at 2 clinical sites. Up to 20 subjects will receive study treatments. Following study treatments, follow-up visits will occur at 60, 90 and 180 days from each subject's last study treatment.

Stroke, a leading cause of disability in the aging population, increases the risk for diabetes, subsequent stroke recurrence, and cardiovascular disease complications. The downsizing of private and federal health care resources, along with the anticipated increase in stroke rates as our population ages, mandate that alternative strategies be developed to reduce the public health burden of stroke. This pilot study may facilitate our knowledge of the timing of paretic leg muscle atrophy, fiber type shift, and the progression of worsening of glucose tolerance after stroke. Knowledge of the skeletal muscle changes occurring in the sub-acute stroke period is essential to create new guidelines incorporating exercise rehabilitation, much like cardiac rehabilitation, in order to facilitate and improve the health care of veteran stroke survivors.

After people lose an eye, for whatever reason, they often experience fat atrophy of the tissues in the orbit. This leads to a sunken appearance that is often not correctable by a cosmetic shell prosthesis. Current techniques to correct this deformity are inadequate/ invasive. Injection of various gels (Restylane, Radiesse) are temporary had have their own disadvantages. This study seeks to demonstrate an improvement in the retention of injected autologous fat by mixing in autologous PRP (platelet rich plasma).

The purpose of this study was to compare the development of new geographic atrophy in patients with wet Age-related Macular Degeneration (AMD) when treated with either ranibizumab or aflibercept over 24 months. Geographic atrophy is an advanced form of AMD that can result in the progressive and irreversible loss of visual function over time.

immobilization of yoked extra-ocular muscles in the anophthalmic orbit, in conjunction with platelet-rich-plasma, will improve integration of viable adipocytes injected into orbital fat

The purpose of this study is to find out how long it takes the vagina to respond to hormonal vaginal cream in women with pelvic organ prolapse (bulge in the vagina). It also will address the appropriate amount to use prior to vaginal repair of pelvic organ prolapse.

The purpose of this study is to analyze the volumetric gain and stability of the newly formed bone tissue comparing guided bone regeneration with block graft.
