Ghrelin, Growth Hormone and Growth Factors at High Altitude

Regulation of ghrelin, growth hormone and growth factors at high altitude and their change during ascent to high altitude has not been studied in depth yet. The study includes 33 volunteers (12f) investigated at sea level, 4 days after ascent to 3440m and 14 days after ascent to 5400-5900m. The investigators hypothesized that during ascent growth hormone levels would increase to compensate for the higher energy needs at high altitude.


Early Signs of Altitude Illness in Patients With COPD

This study evaluates whether structured self-monitoring (SSM) by a symptom checklist in combination with a pulse oximeter worn at the wrist allows lowlanders with COPD to accurately identify whether or not they will experience an altitude-related illness during altitude travel.

Physiological Adaptations to Simulated Intermittent Altitude on Human Health and Performance

The investigators expect to find that different intensity and altitude exposure levels will show what kind of intermittent exposure protocol is more beneficial to athletes and healthy individuals that experience acute exposure to altitude during exercise. This may furthermore be related to acute altitude exposure for recreational exercise use as well.


Effects of Aircraft Cabin Altitude on Passenger Comfort and Discomfort

Commercial aircraft passengers are exposed to atmospheric pressures ranging from the pressure found at ground level to that encountered in the external environment at 8,000 feet. There is some evidence in the medical literature that symptoms of acute mountain sickness can result from ascent to altitudes of 6,300 to 10,000 feet by unacclimated persons during the first few days following ascent, probably due to the hypoxia that results from breathing air at the reduced ambient p...

Sickness Evaluation at Altitude With Acetazolamide at Relative Dosages

This double blind randomized trial will compare acetazolamide taken the morning of ascent to acetazolamide taken the evening prior to ascent for the prevention of acute mountain sickness (AMS). The day of ascent dosing has not been studied as a powered primary outcome. The study population is hikers who are ascending at their own rate under their own power in a true hiking environment at the White Mountain Research Station, Owen Valley Lab (OVL) and Bancroft Station (BAR), Banc...

Acclimatization Mechanisms During Ascent to 7500m

The trial evaluates the role of ascent protocol on acute mountain sickness and cardio-respiratory physiology during an ascent to Muztagh Ata (7546m). Two groups of mountaineers ascend with different acclimatization time to the summit. The prevalence and severity of symptoms of acute mountain sickness are evaluated along with physiologic variables.

Saliva Cortisol Measurement as a Screening Test for Suspisious Cushings Syndrome in Children.

Cortisol overproduction ( Cushings syndrome) is a condition where the patient have a special fat distribution, with accumulation of fat around the abdomen and in the neck, with thinner limbs and weak musculature. The condition can be difficult to separate from adiopsitas in general. Screening for hypercortisolism in adults has been easier the last years, because we can measure free cortisol in saliva samples at late night. In children we still dont have reference ranges for sal...

Altitude Sickness Prevention and Efficacy of Comparative Treatments

This study is designed to be the first to examine the novel drug budesonide for prevention of acute mountain sickness in comparison to acetazolamide and in the context of rapid ascent to high altitude. The investigators will accomplish these objectives with a prospective, double blinded view of a large population of hikers who are ascending at their own rate in a true hiking environment.

Acute Exposure to High Altitude on Symptoms

Randomized crossover Trial in patients with Pulmonary Hypertension (PAH, CTEPH) to assess the acute response to High Altitude (2500m above sea level) in altitude related symptoms

Hair Cortisol and Testosterone Levels in Patients With and Without Acute Myocardial Infarction(MI)

The purpose of this study is to determine whether hair levels of cortisol and testosterone are elevated in patients with acute MI compared to controls.

Training in Hypoxia to Prevent Acute Mountain Sickness

Some studies suggest that high-altitude related illnesses - like acute mountain sickness - could be prevented by acclimatisation, reached at low altitude using training in simulated altitude. The purpose of this study is to determine whether training in hypoxia is suitable to prevent acute mountain sickness.

Susceptibility to High Altitude Pulmonary Edema in Subjects With Increased Hypoxic Pulmonary Vasoconstriction

It has been shown, that subjects susceptible to high altitude pulmonary edema (HAPE)are characterized by an abnormal increase of pulmonary artery pressure at rest in hypoxia and during exercise in normoxia. This abnormal rise of pulmonary artery pressure has also been observed in about 10 % of otherwise healthy subjects without prior altitude exposure. The aim of the study is to investigate the susceptibility to HAPE in unacclimatized subjects with abnormal increase of pulmonar...

Pulmonary Function at High-Altitude

Based on the findings of decreased vital capacity, decreased FEV1 and increased closing volume after ascent to high altitude, some investigators suggest the presence of a subclinical high altitude pulmonary edema (HAPE). Since these parameters are only indirect measures of pulmonary interstitial fluid accumulation, the aim of this study is to examine the effects of broncho-constriction on the increase of closing volume by extensive lung function testing in healthy mountaineers ...

Anti-Oxidant Supplementation for the Prevention of Acute Mountain Sickness

Acute mountain sickness (AMS), high altitude pulmonary edema (HAPE), and high altitude cerebral edema (HACE) are complications of rapid ascent to high altitude. Several features suggest that raised intracranial pressure (ICP) may be an important factor in the pathogenesis of AMS. Magnetic resonance imaging of HACE patients has demonstrated that the oedema in HACE is of the vasogenic, rather that cytotoxic, type. Thus it is likely that cerebrovascular permeability has an importa...

Decompression Tables for Diving at Altitude

The aims of this proposal are to test current USN procedures for adjusting decompression procedures during air diving at 8,000 and 10,000 ft altitude and to provide a decompression algorithm for no-stop dives to 100 feet of sea water (fsw) at 10,000 and 12,000 ft altitude using enriched O2 (PO2=1.3 ATM). Additionally, the experiments will determine whether a period of hyperbaric hyperoxia, such as would be experienced during a dive at altitude, reverses altitude acclimatization...

T89 in Prevention and Treatment of Acute Mountain Sickness (AMS) During Rapid Ascent

To evaluate the safety and efficacy of T89 in preventing Acute Mountain Sickness (AMS) and relieving the symptoms of AMS during rapid ascent.

Effect of Augmented Reality Books on Cortisol Levels in Hospitalized Pediatric Patients

Hospitalization is a stressful event that might impact in a patient's recovery. Children are more susceptible to suffer acute stress as a result of a hospital stay. Stress is often quantized using cortisol levels, a substance which increases following stressful stimuli. Since stress management is important in a patient's recovery, different therapies are used and have been evaluated and proven effective to diminish cortisol levels such as play interventions and clown therapy. N...
