Mechanisms of Disuse Atrophy in Human Skeletal Muscle (iMOB)
Muscular AtrophyImmobility SyndromeLoss of muscle can be caused by a variety of stimuli and results in reduced mobility and strength and also impacts whole body health. Whilst it is known that muscles waste the process by which this occurs is not well understood. Furthermore, whilst some muscles waste quickly others seem resistant to the effects of disuse. This study aims to evaluate how quickly changes in muscles start to occur, and investigate the processes which underlie muscle atrophy. By studying muscles which waste quickly and those which are resistant to atrophy this study aims to identify the different processes which lead to muscle loss. This study will also evaluate the differences in muscle changes between young and old people.
Quality of Life of Caregivers and Patients Suffering From Multiple System Atrophy
Multiple System AtrophyMultiple system atrophy (MSA) is a rare and fatal neurodegenerative disorder that cause as other neurodegenerative diseases profound declines in functioning and thus, require caregiving for assistance with daily living. The aim of the study is to evaluate the effect of a multimodal intervention as proposed by the NYU Caregiver Counseling and Support Intervention (NYUCI) on the quality of life of patients and their caregivers.
Physiologic Volume and Atrophy of Brain and Spinal Cord Measured by Magnetic Resonance Imaging
Cognitive ChangeAtrophy Brain2 moreSpinal cord (SC) involvement is prevalent in multiple sclerosis (MS) and contributes importantly to disease progression. To be able reliably evaluate spinal cord volume and its changes in MS patients we need to understand variability of these parameters in sex and age matched healthy controls (HC). To date, no generally available data about these parameters in HC are available. The objective of this study is to investigate age and sex matched HC by MRI to get the basic set of the data representing both cross sectional values and its longitudinal changes. The present study will also investigate different strategies how to normalize the absolute spinal cord and brain volume data, what is a relationship between spinal cord volume and brain volume and what is the best protocol to be used in a routine clinical practice.
Postoperative Electrical Muscle Stimulation (POEMS)
Muscle AtrophyPostoperative ComplicationsPatients lose a significant amount of muscle following major abdominal surgery. This is partly due to a catabolic response to the surgical insult and inflammation, but is also probably due to a lack of muscle use secondary to immobility. This study will aim to assess whether some or even all of postoperative muscle loss in the upper leg muscle group is preventable through electrical muscle stimulation to mimic physical activity.
Mobilization With Neuromuscular Electrical Stimulation in Critical Care Patients
Muscular AtrophyNeuromuscular electrical stimulation in pectoral muscles (fibres of the pectoralis major muscle bilaterally) and rectus abdominis muscles (bilaterally) preserves / decreases the loss of muscle mass.
Measuring Geographic Atrophy in AMD Patients Using the Nidek MP-3 Microperimetry Device
Age-related Macular Degeneration (AMD)The investigators would like to know if different imaging devices can improve the quality of images and visualization of imaged tissues. Also, the investigators would like to find out whether these changes are useful in the diagnosis and treatment of eye diseases. Using images of previous participants will allow us to demonstrate the advancement of different technologies, as well be used to allow comparisons between current technologies.

Comparison of Brain Atrophy Rates, Cognition, and Patient-Reported Outcomes in MS Patients Using...
Multiple SclerosisRates of brain atrophy for long term users of fingolimod when compared to glatiramer acetate have not been examined in patients with relapsing forms of multiple sclerosis (MS). As patients on long term therapy typically have little or no overt signs of white matter inflammatory activity (T2, gad lesions), brain atrophy measures can provide insight into whether there is continued progression of MS in these patients. What remains unknown is whether patients on a particular therapy have a slower rate of brain atrophy. This would provide convincing evidence that central nervous system tissue injury is further suppressed. Such information would be of substantial clinical benefit when deciding between various therapies. The investigators will estimate the impact of long term use of fingolimod therapy (defined as a minimum of two years on therapy) on whole brain atrophy in treated patients with relapsing forms of MS as compared to age and gender matched patients on Glatiramer Acetate. The investigators secondary goal is to determine the correlation between brain atrophy and cognitive performance in treated patients with relapsing forms of MS. The investigators will also examine the correlation between the NeuroQualityofLife (NeuroQOL) PROs, patient self-reports of disability, clinical assessment of physical disability, work productivity, clinical assessments of cognitive functioning with whole brain volume loss for patients on long term fingolimod vs. long term glatiramer acetate therapy matched on age and gender. The investigators anticipate the findings of this study will generate relevant hypotheses about these relationships.
