The study will begin with 2 days of studies in San Francisco (sea level baseline). Measurements will include non-invasive measurements of blood and tissue oxygen and venous blood draws for cytokine levels.
The altitude part of the study involves ascent to the University of California's White
This study was designed to bring together elements of prior studies and go one step further for definitive data on several points. The trial will employ two pharmaceutical intervention arms, which will compare placebo (the standard of care - information on prevention of altitude sickness) with the
Introduction : very long distance mountain trail which is particularly demanding for the organism. This kind of competition is likely to have an impact on the athlete's health and / or physical integrity. It is assumed that many participants may use medication in an attempt to i) prevent and /or
The specific aim of this study is to evaluate if acetazolamide will be similar to ibuprofen (i.e. Ibuprofen being non-inferior) in decreasing the incidence of Acute Mountain Sickness (AMS) in travelers to high altitude. It has been shown that ibuprofen taken 3 times a day 6 hours prior to ascent is
Acute mountain sickness (AMS) is a well-known disorder in sojourners to high altitude (>2000m) characterized by headache, nausea and tiredness, akin to hangover-like symptoms. The Lake Louise criteria for AMS was primarily developed to allow uniformity in comparing the prevalence of AMS in different
The high-altitude pulmonary edema (HAPE) is the leading cause of death from high altitude sickness. At moderate altitude (2500-4500m) the incidence (0.2-6%) may be underestimated because only clinical HAPE leads to symptoms and motivates the patient to seek medical advice. Cremona et al. [Cremona et
There are many physiological situations in which the organism is exposed to hypoxia, such as exercise and altitude. In addition some pathological situations also involve hypoxia, such as obesity, heart failure, respiratory failure and sleep apnea syndrome.
Hypoxia associated with altitude is
The study will be conducted in Cache County, UT. Surrounded by tall mountains (2513-3042 m), and subject to frequent winter atmospheric inversions characterized by stagnant air that traps and concentrates pollutants, Cache Valley, home to 120,000 inhabitants, is particularly susceptible to high
A patent foramen ovale (PFO) is present in ~30% of the general population. The PFO has historically been considered to be trivial. However, recent work by the investigator's group and others has identified that, compared to individuals without a PFO, those with a PFO have a higher core body
Cardiovascular Disease (CVD) is the primary non-communicable cause of global mortality killing more than 7 million people per year. Chronic inflammation plays a crucial role in the genesis of atherosclerosis which further leads to cardiovascular disease. Apical periodontitis is "an acute or chronic
Materials and methods Subjects (patients) Patients derived from a population of patients referred to 12 months follow-up coronary angiography for ischemic heart disease who are enable to be performed IVUS will be enrolled in the present trial, between Dec 2017 and Dec 2018. The study was an all
Dark chocolate is rich in flavonoids, bioactive micronutrients that increase the bioavailability of nitric oxide as well as decrease the rate in which nitric oxide is removed from the body. Through increasing the bioavailability of nitric oxide (NO) to bodily tissues, the tissues are better able to
Currently, there is no "cure" for spinal cord injuries (SCI). Although the scientific understanding of central nervous system (CNS) regeneration has advanced greatly in the past twenty years, there are still many unknowns with regard to inducing successful regeneration, especially with chronic SCI.
BACKGROUND:
Children and adolescents with CKD have high rates of hospitalization, and those with End-Stage Renal Disease (ESRD) have a remaining life expectancy of about 20 years with increased risk of premature death due to cardiovascular disease. Most have much less physical endurance than their
