La ansiedad como factor de riesgo de tabaquismo en estudiantes de medicina de la Universidad Mayor de San Andrés, su prevalencia, incidencia y las alteraciones espirométricas secundarias a grandes alturas (3.600 M.S.N.M.) Estudio bietápico
(Revista Cuadernos, 2016)RESUMEN. Introducción. El tabaquismo es una enfermedad adictiva, con prevalencias elevadas en estudiantes de medicina, en quienes la ansiedad generada por el modelo académico exigente es un factor de riesgo. Este es ... -
Aymara children are protected from high-altitude-induced pulmonary hypertension
(High Altitude Medicine & Biology, 2005-02-22)Pulmonary hypertension is a hallmark of the adaptation to ambient lack of oxygen. This assumption is also thought to hold true for high-altitude native children, since invasive studies showed elevated pulmonary-artery pressure ... -
La circulation cutanée au cours de l'adaptation à l'altitude
(Pflügers Arch., 1969)Résumé. Débit, pression et volume ont été mesurés dans la main droite considérée comme représentative de la circulation cutanée. Ces mesures ont été faites comparativement à basse altitude (50 et 400 m) et à haute altitude ... -
Comparison of cisternal and lumbar cerebrospinal fluid pH in high altitude natives
(Pflügers Arch., 1975)Summary. Samples of cisternal or lumbar cerebrospinal fluid were obtained from 20 young male volunteers born and living at high altitude (3500 to 4800 m). The pH, carbon dioxide and oxygen tensions, and bicarbonate ... -
Does chronic mountain sickness (CMS) have perinatal origins?
(Respiratory Physiology & Neurobiology, 2007-06-29)Abstract. Chronic mountain sickness (CMS) occurs in 10% of male high-altitude residents. It is characterized by hypoventilation and hypoxemia but its underlying cause remains unknown. We hypothesized that CMS' origins ... -
Effects of exercise on plasma erythropoietin in natives living permanently at high altitude
(Springer Verlag, 1992)Abstract. The effects of inspiratory hypoxia on the erythropoietin (EPO) system decisively depend on the duration of the exposure to the hypoxic environment. Whereas a stay of some hours in a hypobaric chamber leads to ... -
Effets de l'oxygénation sur la réponse ventilatoire au CO₂ chez l'homme à haute et basse altitude

Estudios cardiorespiratorios en la enfermedad crónica de la montaña (Síndrome de Monge)
(Revista IBBA, 1972)Resumen. Comparación entre 14 individuos normales jóvenes del sexo masculino y 20 enfermos con síndrome de Monge. Se mostró que éstos últimos tienen una superficie corporal media, una hemoglobina, volumen tidal en reposo ... -
Evidence that parent-of-origin affects birth-weight reductions at high altitude
(American Journal of Human Biology, 2008-02-19)Abstract. Hypoxia exerts a profound depressant effect on fetal growth, lowering birth weight, and raising mortality risk. Multigenerational high-altitude populations are relatively protected from this birth-weight decline, ... -
Excessive polycythemia occurs in young high-altitude (3600 M) residents in the absence of lung disease
(High Altitude Medicine & Biology, 2002-04-18)Objective: Chronic Mountain Sickness occurs in , 8% of the La Paz population. We asked whether its primary diagnostic sign, excessive polycythemia (EP), occurred in youngeraged persons without lung disease. Methods: ... -
Fútbol en la altura en Bolivia
(Cuadernos del Hospital de Clínicas, 2009)RESUMEN. El presente trabajo se realizó en razón del tercer veto emitido por la FIFA, de jugar partidos eliminatorios para Copas Mundiales de Fútbol en alturas por encima de los 2500 m. Los objetivos del estudio se basaron ... -
Haemoglobin concentration and lung diffusing capacity in man at low high altitude
(Compterendus des séances de la Société de Biologie, 1982)Resumen. Lung diffusing capacity (DLCO) was measured using a steady state method in high (3600 m.) and sea level natives. Correlation was found between DLCO, height, age and haemoglobin concentration. Regression coefficients ... -
Heat exchange and energetic balance during exercise in highlanders and lowlanders at sea level and high altitude
(Environmental Physiology, 1973)This study was designer to determine the effects of changes in both cutaneous circulation (15) and kinetics of oxygen uptake (20) at high altitude on mechanisms of heat exchange during exercise. From a theoretical point ... -
High-altitude ancestry protects against IUGR and reductions in birth weight associated with high altitude and preeclampsia
(High Altitude Medicine & Biology, 2005-02-22)Background. Observations consistently demonstrate diminished birth weight [BW] with ascending altitude; however population comparisons reveal the extent of BW reduction depends, in part, upon high-altitude ancestry. ... -
High-altitude haematology : Quechua-Aymara comparisons
(Annals of Human Biology, 1981)Summary. Haematological studies have been carried out al various altitudes between 450 m and 4800 m, on two separate human groups (Quechuas and Aymaras) living in South America. Changes in the haematological parameters ... -

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 ... -
Metahemoglobinemia de altura. Metahemoglobina y NADH diaforasas
(Sangre, 1982)RESUMEN. La elevación de la tasa de metahemoglobina en las grandes alturas es una de las consecuencias de la modificación metabólica provocada por la hipoxia de altura que sufre el eritrocito. Por el estudio de la evolución ... -
Oxygen deficit and debt in submaximal exercise at sea level and high altitude
(Journal of Applied Physiology, 1974)Kinetics of O₂ uptake (Vo₂) during exercise (3 work loads, 2 time periods) show that for a given work load O₂ deficit is larger at high altitude (HA) than at sea level (SL). However, the relationship between deficit and ...
