Filter by:Sleep is a physiological state that is essential for human performance, including academic, occupational, interpersonal, and psychological aspects. Sleep disruption or deprivation leads to a loss of psychomotor skills and an increased association with various diseases. Therefore, it is critical to assess how chronic sleep deprivation affects medical residents who work long shifts, including those assigned during their training.
This study aims to determine, via skeletal muscle ultrasound (US), the extent, timing and relationship between skeletal muscle mass loss and outcomes after orthotropic heart transplantation (OHT) and left ventricular assist device (LVAD) implantation amongst patients with cardiogenic shock. Advanced therapies such as OHT and VADs in the heart failure (HF) population may promote skeletal muscle mass and subsequent quality of life, but there is a lack of literature assessing muscle mass changes in HF patients before and after advanced therapies using US imaging. Therefore this observational study will provide further insight into the 1) changes in lean body mass during critical illness and 2) the feasibility of using bedside US to assess lean body mass in the inpatient setting.
This study will characterize intramuscular molecular mechanisms underlying anabolic resistance to protein ingestion during muscle disuse. Adults (n=12) will be studied using a unilateral leg immobilization model in which one leg will be randomly assigned to immobilization and the contralateral, active leg used as a within-subjects control. Immobilization will be implemented for five days using a rigid knee brace, during which time participants will ambulate using crutches. Integrated ribonucleic acid (RNA) synthesis will be determined during immobilization in the immobilized and non-immobilized legs using ingested deuterium oxide, salivary and blood sampling, and muscle biopsies. Immediately after immobilization, muscle biopsies will be collected before and 90 mins after consuming 25 g of whey protein from the immobilized and non-immobilized legs to characterize the intramuscular molecular response to protein feeding. Serial blood samples will be collected during that time to characterize the circulating metabolic response to protein ingestion. Knowledge generated from this effort will inform the development of targeted interventions for mitigating anabolic resistance to protein ingestion that develops during periods of muscle disuse.
Many methods utilize for acne scar treatment including laser, cosmetic filler, microneedling, local tumescent, Subcision and chemical peels. These procedures can be used individually or as a combination therapy. Combining procedures give better results. In our study we will try in the period from March 2024 to March 2026, to assess the efficacy of combination of scar subcision with platelet rich plasma, Polydioxanone mono threads or fractional Carbon dioxide laser in the treatment of severe atrophic acne scars with 1:1:1 ratios and to compare between these modalities regarding safety and efficacy.
The purpose of this clinical trial was to evaluate the safety and tolerability for 12 weeks after one dose of TRTP-101 in adults with atrophic scars.
However, recently, most described techniques for posterior atrophic maxillary rehabilitation, are targeting more conservative, cost-effective and efficient methods for sinus elevation eliminating its lateral access. The aim of the present study is to evaluate and compare the long-term implant stability for implants placed by the novel crestal sinus approach versus osseodensification using Densa-bur in Atrophic Posterior Maxilla.
The primary objective of this clinical investigation is to demonstrate that treatment with the VITA AV clinical system is feasible and to evaluate clinical performance and safety when used to improve the symptoms and signs of vaginal atrophy (VA) due to menopause.
This is a 10-week human study involving 24 younger (20-35 y) and 24 older (65-85 y) healthy individuals. All participants will undergo unilateral immobilization of a knee for 7-10 days, followed by 4 weeks of heavy resistance exercise training (HReT). Half of the participants (12 younger and 12 older) will also undergo 4 weeks HReT prior to the immobilization. Prehabilitative exercise may confer protective effects on subsequent immobilization, and the various underlying mechanisms involved
Despite declining incidence rates, gastric cancer (GC) ranks the fourth leading cause of cancer-related mortality and the fifth most common cancer worldwide, with the highest incidence reported in Eastern Asia. The 5-year overall survival rate of early GC exceeds 90%, which was well above advanced GC. Most intestinal-type GCs follow the Correa cascade-inflammation,atrophy, intestinal metaplasia (IM), dysplasia and subsequent carcinoma. The presence of gastric mucosal atrophy and intestinal metaplasia are important risk factors for GC. The purpose of this study was to investigate the incidence of GC attributed to atrophic gastritis in a region with high incidence of GC.
The New York Stem Cell Foundation (NYSCF) Research Institute is performing this research to accelerate diverse disease research using cells from the body (such as skin or blood cells) to make stem cells and other types of cells, conduct research on the samples, perform genetic testing, and store the samples for future use. Through this research, researchers hope to identify future treatments or even cures for the major diseases of our time.
