Iron metabolism in high-altitude residents
(American Physiological Society, 2020)
Residents at high altitude cope with decreasing inspiratory oxygen partial pressure by stimulating erythropoiesis. The increase in hemoglobin levels requires high amounts of additional iron supplied from the diet. Here, ...
Maternal adaptation to high-altitude pregnancy : an experiment of nature-a review
(Placenta, 2004)
A long and productive history of studies at high altitude has demonstrated that chronic hypoxia plays a key role in the aetiology of intrauterine growth restriction (IUGR) and pre-eclampsia. Susceptibility to altitude-associated ...
Higher estrogen levels during pregnancy in Andean than European residents of higy altitude suggest differences in aromatase activity
(J Clin Endocrinol Metab, 2014-08)
Context: Uteroplacental hypoxia has been reported to lower estrogen levels in preeclampsia as the
result of reduced aromatase activity.
Objective: We asked whether the chronic hypoxia of residence at high altitude in the ...
Hemoglobin Levels in Peruvian Patients with Chronic Kidney Disease at Different Altitudes.
(Mary Ann Liebert, 2023)
Background: Decreased hemoglobin is a manifestation of chronic kidney disease (CKD), and people who reside at high altitude adapt to hypoxia by increasing their hemoglobin. The study's objective was to determine the ...
Microalbuminuria in healthy adolescents: A comparative study at high altitude and at sea level
(Bentham Open, 2014)
Background : High altitude is associated with hypobaric hypoxia and increased risk for microalbuminuria in adults. We hypothesized that healthy adolescents at higher altitude might have an increased frequency of microalbuminuria ...
The Increase in Hemoglobin Concentration With Altitude Differs Between World Regions and Is Less in Children Than in Adults.
(Wolters Kluwer Health, 2023)
To compensate for decreased oxygen partial pressure, high-altitude residents increase hemoglobin concentrations [Hb]. The elevation varies between world regions, posing problems in defining cutoff values for anemia or ...
Effect of altitude on mortality of end-stage renal disease patients on hemodialysis in Peru
(Oxford University Press, 2020)
Background: In Latin America, the prevalence of end-stage kidney disease (ESKD) has risen tremendously during the last decade. Previous studies have suggested that receiving dialysis at high altitude confers mortality ...
Cerebral glucose metabolism and cerebral blood flow in high-altitude residents
(Journal of Applied Physiology, 1974)
The present study was performed to evaluate the hypothesis that an increased H+ production by the brain from lactic acid formation during hypoxia a role in the lowering of the bicarbonate concentration. Twenty –three ...
High altitude reduces infection rate of COVID-19 but not case-fatality rate
(ElsevierNL, 2020)
Coronavirus disease 19 (COVID-19) is a pandemic caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). It is suggested that life at high altitude may reduce COVID infections and case-fatality rates ...
Edema agudo de pulmón de reentrada a gran altitud
(Universidad San Martín de Porres. Facultad de Medicina HumanaSeguro Social de Salud (EsSalud)PE, 2020)
El edema agudo de pulmón de altura es una condición médica potencialmente mortal. Se conoce también como edema agudo de pulmón de altura “de reentrada” y puede ocurrir en residentes de la altura que retornan de una estadía ...
