one measurement of pain threshold in high altitude and in low altitude using pressure algometer and Situational pain scale.
Over 30% of American adults have hypertension (HTN) (high blood pressure), and the rate increases considerably with age; 64% of men and 78% of women over 65 have HTN. High blood pressure associated with HTN can force of the blood against artery walls with enough pressure that it can eventually cause health problems, such as heart disease and stroke. HTN is one of the most significant causes of early death worldwide and one of the most preventable causes of death. Many studies reveal that lowering blood pressure (BP) reduces the incidence of diseases of the heart and blood vessels. Non-drug related treatments are known to reduce BP which can have a great effect on public health. Research suggests that Tai Chi (TC) is effective in lowering BP in patients with HTN, but because of the low quality of existing studies there is no definite proof. Also, it is not known how TC reduces BP. One possibility is that TC practice, which is shown to reduce psychological distress such as anxiety and depression and reduce the body's responses to stress, can improve the balance of the autonomic nervous system (the part of your nervous system that controls beating of the heart and the widening or narrowing of blood vessels). This may lead to lower BP. The investigators plan to investigate the pathways among autonomic, blood vessel, immune and psychological factors in relation to BP changes in response to 12-weeks of TC compared with Healthy Aging Practice-centered Education (HAP-E). 250 older adults (60+ years old) with mild HTN will be enrolled, and the investigators will take several measurements of heart and nervous system functioning. The investigators hypothesize that performing TC for 12 weeks will result in autonomic "re-regulation" which will improve BP and blood vessel health (Aim 1) and sympathetic nervous system (part of the nervous system that serves to speed up heart rate, contract blood vessels, and raise blood pressure) regulation of the immune system (Aim 2). Lastly, the investigators hypothesize that psychological factors will be related to TC effects on autonomic regulation (Aim 3). Findings from the investigators study will hopefully shed light on the pathways by which TC reduces BP. Also, the particular effects of TC ("meditative movement") in an older, "hard-to-treat" hypertensive population will be better understood.
Breast surgeries are usually associated with significant postoperative pain. Suitability of analgesic technique after breast surgery is always questionable. The aim of this study is to compare US guided Pecs II block versus thoracic paravertebral block performed by US guidance as regards to potential complications and analgesic efficacy of both techniques in the first 24 h after modified radical mastectomy.
The benefit of drug therapy to persons with diabetes has been well established in clinical trials in terms of reducing cardiovascular risk, microvascular complications and mortality. However, treatment adherence and treatment effectiveness continue to be challenges in diabetes management. Rimidi Diabetes has developed software algorithms to simulate the effect of anti-diabetic medications on an individual's glucose profile, allowing the clinician and their patient to visualize the anticipated outcome of a medical intervention. Use of this technology should allow for more targeted decision-making by the clinician and should facilitate a shared decision-making process with the PwD who is now privy to the thought process behind their medical management. The proposed study is designed to test whether adding a decision support capability (Diabetes+Me Rx) that allows for modeling the anticipated effect of medication adjustments leads to improved glycemic control and a perceived benefit by healthcare providers and PwDs.
The purpose of this study is to create an electronic registry to house phenotypic information from patients with achondroplasia. The initial focus of this registry will be to include U.S. patients with achondroplasia. Once populated, the collective data can be queried to pursue clinical research questions pertaining to health outcomes and treatment options for patients with this conditions. The registry is longitudinal in nature with the functionality to retrospectively enter patients' clinical data from the prenatal period up through the most recent encounter, with all intervening data entered in a chronologic fashion.
This study aimed to verify the effects of propofol for treatment on emergence agitation (EA) after sevoflurane anesthesia in pediatric strabismus surgery.
The present study aims to assess the effectiveness of three different retention schemes used to maintain tooth position after orthodontic treatment with fixed orthodontic appliances (stability) and to evaluate possible association between retention scheme and gingival recessions on the lingual surfaces of the lower anterior teeth seen for up to 5 years post-treatment. Moreover the possible association between primary relapse tendency and long term occlusal stability will be evaluated.
The objective of the study is to evaluate the impact of strength training on sleep apneas in the elderly. Individuals aged between 65 and 80 years and that presenting apnea-hypopnea index between 20 and 50 events per hour, measured by out-of-center portable polysomnography, will be recruited. Those included will be randomized to two groups: Intervention: consisted of 12 weeks, twice a week, of strength training; or control: consisted of lifestyle recommendations.
To determine the prevalence of 5 specific corneal dystrophies in a subgroup of patients seeking refractive surgery, and to use that information to inform them and their refractive surgeons of the presence of the corneal dystrophies so that they may make safer choices when considering refractive surgery.
The aim is to study the use of Ocusweep system especially in driving health evaluation and compare the results produced by Ocusweep system to those of conventional devices. The main focus is in patients suffering from wet age-related macular degeneration. The study aims to find out how frequently these patients do not meet the European Union health criteria of safe driving and how Ocusweep finds these patients from a population of patients being treated in a busy medical retina clinic. The tests of Ocusweep system are compared against conventional visual field tests, contrast sensitivity tests, visual acuity tests and tests showing anatomical changes related to wet age-related macular degeneration (optical coherence tomography, fundus photography and fluorescein or indocyanine green angiography).
