Active clinical trials for "Atrophy"

VAGINAL PRASTERONE in the treatment of VAGINAL ATROPHY IN PATIENTS WITH BREAST CANCER TREATMENT WITH AROMATASE INHIBITORS (VIBRA STUDY)

Multiple system atrophy (MSA) is a rare and fatal neurodegenerative disease characterised by a variable combination of parkinsonism, cerebellar impairment and autonomic dysfunction. The neuropathological hallmark is the accumulation of alpha-synuclein in oligodendrocytes. While some symptomatic treatments exist, neuroprotective treatments for MSA remain an urgent, unmet need. Moreover, at present there is not a single surrogate biomarker of MSA which could be used to inform clinical trials. This study seeks to characterise the natural history of MSA on a panel of candidate biomarkers, pre-selected for being putative surrogates of the underlying neurodegenerative process

The decline in physical function and strength was seen by the nature of aging. The older adults often complain of fatigue. For these reasons, proper rehabilitation approaches should be used to ensure healthy life and to keep the quality of life at the highest possible level by minimizing the decline seen with aging process. Exercise programs and Neuromuscular Electrical Stimulation (NMES) are applied in rehabilitation to restore muscular strength and improve physical performance. NMES is used to prevent the atrophy of nonuse, to increase joint range of motion, to re-educate muscle, to regulate spasticity, to replace orthosis, to improve motor involvement of muscle fibers. Despite the use of NMES for strengthening in the clinics, the application parameters and methods should be discussed. The frequency, the pulse duration, the on / off time, the amplitude, the waveform of the current and the application time vary between the studies. For geriatric populations, it is recommended that the highest intensity, biphasic symmetrical currents with a frequency in the range of 50-100 Hz, for 100-400 μs, can be pulsed for ideal amplification. NMES is usually practiced by physiotherapists continuously for 20 minutes in to strengthen. However, in recent studies, it has been shown that continuous application of a single-session 100 Hz current for 20 minutes leads to intense fatigue and after a while the effect of the strengthening of the current has been removed. Therefore, intermittent applications have been proposed instead of continuous applications for 20 minutes. Considering the fragility and the presence of sarcopenia in the geriatric population, NMES applications should be preferred in which rest periods are given instead of continuous application for 20 minutes. In the literature, there is no study showing the effect of NMES on Quadriceps strength, fatigue and physical function by using quadriceps stimulation for 20 minutes using different stimulation periods.Therefore, in this study, will be investigated the possible effects of two different methods of NMES on Quadriceps strength, fatigue and physical function.

Plantar heel pain is the most common problem of the foot. Plantar fasciitis is the leading cause of this pain, accounting for 11-15% of all foot symptoms seeking professional care, and occurs in 10% of the US population. The cause of heel pain can be from bone, soft tissue, nerve, or systemic disease. The second most common cause of heel pain is fat pad atrophy, followed by a combination of both fat pad atrophy and plantar fasciitis. [1-4] Fat pad displacement may be seen in the heel as well. Current treatments for plantar fasciitis include stretching and external support with orthotics with the goal of reducing local pressure as well as tissue breakdown.[5] However, patient compliance with extrinsic devices is challenging, and they may experience increased friction, irritation and breakdown at a different location on the foot due to thickness of the device in the shoe. Also, the patient must replace the device as soon as it breaks down but the breakdown often goes unnoticed. Failure of conservative management may lead to treatment with steroids or surgical intervention by endoscopic plantar fasciotomy, open fasciotomy or excision of bone spurs. Injection of steroids can instigate or exacerbate pre-existing heel fat pad atrophy. Autologous fat grafting to the heel may reduce plantar pressures, and thus serve as a treatment for heel pain. Autologous fat grafting is currently under investigation for a myriad of clinical scenarios.[6-19] Even though autologous fat grafting is not yet an established therapeutic approach for the cited indications, some of the reported results have been intriguing.[19] The variable resorption of fat, however, is an important confounding factor in all these studies. Currently the literature reports fat retention rates ranging from 25% to 80%.[20] The specific aim of this study is to assess the adipose stem cell characteristics in patients undergoing autologous fat grafting for heel fat pad atrophy and correlate these characteristics with fat retention. Data from this study will help determine the characteristics of the adipose stem cells in this population and open the door to additional studies. This pilot study will also help build new collaborative efforts between Foot and Ankle Specialists, Plastic Surgery, and Adipose Stem Cell Biologists, combining biomechanical expertise with fat grafting and basic science expertise.

Muscle size declines at around 0.5-1% per year after 50 years of age, with muscle strength declining up to twice as fast as muscle size. This may eventually lead to loss of independence if tasks of daily living become too strenuous to be performed safely. Short periods of bed rest cause very rapid loss of muscle size and strength, and studies using healthy older participants have shown that age increases vulnerability to this muscle loss. However, it is unlikely that healthy individuals would be faced with periods of bed rest unless suffering a severe illness. In light of this, recent evidence has shown that even just reducing walking to less than 1,500 steps per day for two weeks caused 4% loss of leg muscle in over 65 year olds. This amount of activity is roughly the equivalent of being housebound, something that may become more common into older age, for example due to prolonged bad weather, or minor injury or illness. This study will investigate what causes such stark muscle loss during two weeks of reduced activity, and the impact on skeletal muscle function and size, as well as balance, body composition, and other indicators of general health such as how the body responds to food or exercise. Importantly, exercise strategies that could reduce muscle loss during a period of reduced activity will also be investigated. In brief, three groups of 10 older men (aged 65-80 years) will undertake two weeks of reduced physical activity by limiting their daily steps to <1,500/day. All groups will then undertake a re-training exercise programme to ensure that any losses in muscle strength or size are regained. One of the groups will be a control, whereby they will undertake the step-reduction intervention and re-training, but no protective exercise before or during the step-reduction intervention. This group will allow us to achieve our primary objective of determining the influence of two weeks of reduced physical activity on muscle strength and size in healthy older males. The two other groups will undertake either four weeks of strength exercise training before the step-reduction intervention, or daily home based exercise 'snacking' during the step-reduction intervention. The potential protective benefits of the exercise interventions in reducing the impact of two weeks of reduced activity on muscle strength and size, and any effect on how muscle is re-gained afterwards, will be compared to the 'control' group.

The study will examine the effects of fractional/pixel CO2 laser treatment in vaginal atrophy and in vulvar lichen sclerosus by means of histological and immuno-histochemical characterization of the epithelial layers and markers of tissue aging. The tissue characterization will be performed by biopsies of the vaginal or vulvar tissue at three different points of time: prior to treatment, two weeks after the third and last treatment, and one year after the last treatment.

Ageing is associated with a gradual decline in muscle mass that is detrimental to both physical function and metabolic health, increasing the risk of morbidity and mortality. The loss of protein muscle mass with ageing is poorly understood, but it may partly relate to inactivity/disuse (i.e. during injury or hospitalization). Periods of inactivity/disuse blunt the ability of muscle to grow (termed anabolic blunting), leading to a loss of muscle mass and strength. An accumulation of these periods over a lifetime promotes the devastating loss of muscle protein mass and strength seen with ageing. Disuse-induced muscle loss is underpinned by a blunted muscle anabolic response to protein nutrition. Supplementing the diet with the amino acid leucine may offer a potential solution to alleviate muscle mass and strength loss during disuse. In fact, leucine is suggested to promote muscle protein growth and reduce muscle protein loss during disuse in rats, but this is yet to be shown in humans. Accordingly, the proposed study will investigate whether leucine supplementation can offset muscle and strength loss during short-term disuse. Twenty-four healthy (non-obese, non-diabetic, non-smokers) men aged 18-35 years will initially complete a lower-limb strength assessment and undergo a body composition scan three days later. The following morning, participants will be randomly assigned to ingest either 5g of leucine (n=12) or a caloric-matched placebo (n=12) with each meal over a 7 d period of a single-leg immobilisation. Immediately following immobilisation participants will undergo another body composition scan. Additionally, a stable isotope infusion will be combined with serial muscle biopsies from the thigh of each leg to determine the measure rates of muscle protein synthesis in the fasted state and in the 'early' and 'late' phase of feeding. A day later, the assessment of muscle strength will be repeated.
