Filter by:The main objective of this study is to find a correlation between vitamin D deficiency and stress fracture occurrences in athletes who participate in high-risk activities. These high-risk athletes undergo elevated bone turnover, which requires adequate levels of vitamin D in order to support bone health. It is hypothesized that providing supplemental treatment to athletes showing lower than normal serum vitamin D levels will decrease the occurrence of stress fractures. By recording the dates and specific occurrences of fractures, it may be possible to correlate injury rates with seasons, providing more supportive data to pre-existing literature. This area of research is lacking in the quantity of prospective studies. Previous studies primarily focus on adolescent, elder, or military recruit populations. While literature has shown that vitamin D plays an important role in bone health, there are no previous studies that directly examine vitamin D deficiency and supplemental treatment in conditioned collegiate athlete populations. This study will add to the existing knowledge and will provide a more specific analysis for athletes.
Opioids is known that produce not only analgesia but also hyperalgesia through activation of central glutaminergic system-GABA. At the same time, recently it was found that the main opioid receptor (OPRM1) is present on human granulosa cells and exogenous opiates and their antagonists can influence granulosa cell vascular endothelial growth factor (VEGF) production via OPRM1, causing ovarian hyperstimulation syndrome. This study aims to investigate if a single exposure to opioids is enough to produce activation of stress mechanism during oocyte retrieval.
This study is prospective single arm extension study of protocol AAG-G-H-1220. It is open only to participants of AAG-G-H-1220 randomized to the Microfracture treatment group.
The study is a genetic historical cohort study in a military combat recruits - this study does not examine a specific treatment but rather examines a statistical link between medical history of traumatic fractures, clinical diagnosis of stress fractures and the presence of unique SNPs in subjects DNA.
Hypothesis: Diagnostic ultrasound is an appropriate screening test for acute stress fracture in the lower extremity and is superior to x-ray. Primary Aims: To determine if diagnostic ultrasound is an appropriate screening test with high sensitivity and at least moderate specificity for the identification of acute stress fractures of the lower extremity. Methods: In this double-blind, prospective clinical study, subjects (age 14 years and up) suspected to have an acute stress fracture of the lower extremity will be recruited from the Sports Medicine clinic at the University of Virginia Health System in the Department of Physical Medicine & Rehabilitation. Subjects will undergo the traditional diagnostic algorithm including screening x-ray as part of standard care. Subjects will then undergo a confirmatory MRI of the region of concern if the initial x-ray was negative as part of standard care. Any subject who does not require an MRI for clinical purposes (initial X-ray was positive) will have one completed for research purposes. All subjects will also undergo diagnostic ultrasound performed by a separate, blinded physician competent in diagnostic ultrasound for research purposes. A statistician in the Department of Public Health at the University of Virginia will be performing statistical analysis during data analysis. Findings will be analyzed using a McNemar chi-square test to evaluate for significant differences between the sensitivities of ultrasound and x-ray.
Patients who are involved in a clinical protocol driven 12 week medical weight loss intervention will be randomized to receive either a placebo or 600 mg of an ashwagandha root extract. The study endpoints are primarily the patients self-reported perception of life stress and sleep quality. The working hypothesis of this study is that the addition of aschwagandha to .the medical weight loss program will improve the self-reported perception of life stress and sleep quality
Post Market clinical outcomes study to collect data on the short - and long-term outcomes for subjects who are undergoing or who have undergone the Subchondroplasty Procedure in the foot and/or ankle in a standard clinical setting. Outcomes to be assessed include pain medication usage, pain, function, activity levels and patient satisfaction.
1. PURPOSE OF THE STUDY 1.1 Justification The purpose of the project is to examine the effect of breathing biofeedback and thoughts about stress on performance under stress and cigarette cravings. Smoking rates in the United States have been steadily going down over the past 50 years, and now 16.8% of adults smoke (Centers for Disease Control and Prevention, 2015). Most smokers try to quit, but end up going back to smoking (Garcia-Rodriguez et al., 2013; Piasecki, 2006; Rafful et al., 2013). The reasons people go back to smoking may have something to do with stress in their lives, particularly for women who smoke. This study wants to see if we can reduce temporary stress and lower craving to smoke after stress. 1.2 Description of the Research Project Approximately 60 adult women will participate in the study. Participants must be between 18 and 65 years old, able to read English fluently, and must agree to engage in the research procedures (stress protocol, physiological assessment, breathing training, questionnaires) to participate. People who are taking medications that interfere with physiological assessment are excluded from participating including people with: self-identified substance use problems, self-identified psychosis, morbid obesity (BMI>40), and people who take anti-cholinergic medication, beta blockers, Ritalin, benzodiazepines, tricyclic antidepressants or bupropion, varenicline, antipsychotic medication, or nicotine replacement therapy. People who have a cardiac rhythm abnormality or major neurological problem are also excluded from the study. Also, participants may not participate if they are pregnant or color-blind. Participation is strictly voluntary. 2. PROGRESSION OF THIS STUDY 2.1 Procedures The study visit procedures will take place at the Emotion and Psychopathology Laboratory at Rutgers University, located at the Rutgers Institute for Health, Healthcare Policy, and Aging Research. Participants will first complete some questionnaires and provide some basic information about themselves (demographic information, responses to emotion and stress, and smoking history). Next, participants will engage in a baseline psychophysiological assessment where investigators will examine heart rate, breathing, and blood pressure. Next, investigators will either ask participants to sit quietly for 30 minutes while completing a computer task and watching short videos, or practice a specific deep breathing exercise for 30 minutes. Then participants will do three tasks on a computer. The tasks will ask participants to trace different shapes, answer math problems while receiving feedback about how they're doing, and identify colors and words on a screen. Finally, participants will be asked to sit quietly for 15 minutes before investigators remove the psychophysiological recording equipment. One week after the study visit, investigators will contact participants via phone to ask them some questions about the study visit. 2.2 Duration of the study This study visit will last approximately 3 hours. Length of the visit may vary because each individual may complete procedures at a different pace. The phone call after the study visit will last approximately 10-15 minutes.
The current study will investigate the combination of the two modalities in a mixed-methods design, in order to provide comprehensive knowledge regarding the effects of family-centered MT during KC, on premature-infants' autonomic nervous system stability (measured by parasympathetic tone, physiological vital signs and behavioral states); Parents' anxiety levels; And parents' unique experiences of the intervention. Additionally, the study will analyze separately mothers and fathers to elucidate similar and different effects
This study evaluates the effect of a late intervention of continuous skin-to-skin contact (SSC) in the neonatal intensive care unit (NICU). Half of the participants will receive the intervention and the other half will receive standard care.
