Pilot randomized, placebo-controlled trial of nulliparous postpartum women with a perineal laceration following a term vaginal delivery comparing vulvovaginal atrophy symptoms between women using vaginal estrogen in the postpartum period with those using placebo.
The purpose of this study is to try to understand why reversals of amyotrophic lateral sclerosis (ALS) and primary muscular atrophy (PMA) take place. The study will enroll patients with ALS or PMA reversals to give saliva samples in order to determine if the ALS or PMA reversal is because of certain changes in the genetic code.
Phase 3, open-label, single-arm, single-dose, trial of onasemnogene abeparvovec-xioi (gene replacement therapy) in patients with spinal muscular atrophy (SMA) Type 1 who meet enrollment criteria and are genetically defined by a biallelic pathogenic mutation of the survival motor neuron 1 gene (SMN1) with one or two copies of survival motor neuron 2 gene (SMN2). Up to 30 patients < 6 months (< 180 days) of age at the time of gene replacement therapy (Day 1) will be enrolled.
Following orthopedic surgery and/or injury, a significant loss of muscle mass is generally observed. While this loss of muscle mass appears to be the norm, it causes significant problems in both the athletic and general population. Athletes struggle to regain their performance because of the decrease in muscle mass and also have a greater potential for reinjury while they are in a depleted state. In the general population, and particularly among the elderly, this loss in muscle mass can be even more devastating because as people age, it is more difficult to regain muscle after it is lost. In elderly individuals, this loss in muscle mass can lead to significant disability, diminished quality of life along with an increased risk of falls. In addition to the muscle mass lost during the post-operative period, the strength of the muscle also decreases. This has obvious performance implications in athletes, as well as having the potential to extend recovery time. In the elderly, decreased strength may result in reduced independence and inability to perform activities of daily living. Many previous bed rest studies have reported that significant bone loss also occurs during times of decreased mechanical loading. The post-operative period generally results in decreased mechanical loading; however, some muscle loading will still occur during the rehabilitation process. The dynamic relation between muscle activity/loading and bone density changes in the post-operative state has not been fully described and requires further study. With this knowledge of the importance of nutrition to the musculoskeletal system, applying the principles of increased protein intake through the addition of a dietary supplement to a population preparing for orthopedic surgery and subsequent muscle disuse is a logical next step. The investigators hypothesize that through the consumption of a protein-based dietary supplement three times per day (75g protein), along with educating patients on the importance of consuming foods that are high in protein, there will be an attenuation of decreases in muscle mass and strength as well as losses in bone that occur with orthopedic injury and disuse. The investigators long-term goal is to identify a nutritional protocol that can be implemented prior to and following orthopedic surgery to diminish the deleterious effects of the subsequent disuse on muscle and bone.
Patients admitted to the ICU with diagnosis of sepsis and requiring mechanical ventilation for at least 24-hours and receiving enteral or parenteral nutrition will be prospectively randomized to one of two arms. Patients allocated to the estimated energy expenditure group will receive nutrition with caloric intake calculated based on the Penn State equation. Patients randomized to the measured group will receive nutrition with caloric intake calculated based on IC measurement present in the GE ventilator. Patients in the estimated group will have IC performed, but these data will not be used for prescription of nutrition. An equal number of beds within the ICU will be allocated to the measured group and the estimated group. The primary objective is to assess whether the utilization of indirect calorimetry for caloric goal calculation results in improvement in muscular structure, and consequent reduction of mechanical ventilation duration in patients with sepsis in comparison to utilizing the Penn State estimation equation for caloric goal calculation. The secondary objective is to assess whether the utilization of indirect calorimetry for caloric goal calculation results in improved adequacy of nutritional delivery in comparison to the adequacy of nutritional delivered when utilizing the Penn State estimation equation. Adult patients (> 18 years of age) admitted to the hospital with diagnosis of sepsis, and who require mechanical ventilation during hospitalization will be considered. Patients newly ventilated for at least one day but less than three days will be included in the study. Informed consent will be obtained from the legal authorized representative (LAR).
Current semi-occluded vocal tract therapies limit the type of vocalizations that can be produced to single vowels, which does not promote learning of the healthy voice behavior in connected speech or generalization to conversation. However, recent preliminary results using a semi-occluded mask indicate that the use of certain mask port diameters may allow for natural speech production while increasing supraglottal pressure and impedance, and thereby result in elicitation of voice with increased efficiency. In addition, the use of a semi-occluded mask provides the possibility for a better transition from phonating single phonemes in therapy to training the target therapy techniques in connected speech.
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.
A purpose of the present study is to investigate the capability of serum uric acid elevation, safety, and tolerability of inosine 5'-monophosphate in patients with multiple system atrophy with multicenter, randomized, placebo controlled, parallel assigned design. This may provide the cornerstone for future extended trial in multiple system atrophy, a debilitating disease to date.
