Pubertal Hormonal Changes and the Autonomic Nervous System: Potential Role in Pediatric Orthostatic Intolerance

Frontiers in Neuroscience, 2019
Puberty is initiated by hormonal changes in the adolescent body that trigger physical and behavioral changes to reach adult maturation. As these changes occur, some adolescents experience concerning pubertal symptoms that are associated with dysfunction ...

Tirzepatide and Cardiovascular Outcomes: A Narrative Review of Mechanisms, Efficacy and Implications for Heart Failure Management

Endocrinology, Diabetes &Metabolism, Volume 9, Issue 1, January 2026.
Integrated framework for tirzepatide in HFpEF management. Through metabolic, haemodynamic, structural and anti‐inflammatory pathways, tirzepatide modifies the disease trajectory of HFpEF, leading to improvements in symptoms, functional capacity and reduction in HF events.

Heat stress and orthostatic tolerance

Journal of Physical Fitness and Sports Medicine, 2012
In healthy individuals, exercise and nonexercise (i.e. passive body heating) heat stress induces vulnerability in the cardiovascular system, and is apt to cause hypotension during upright posture, resulting in a reduction of orthostatic tolerance ...

A model for plasma volume changes during short duration spaceflight [PDF]

It is well established that plasma volume decreases during spaceflight and simulated weightlessness (bedrest). The decrement in plasma volume is thought to contribute to the orthostatic intolerance that has been observed in some crew members following ...

Galanin and Adrenomedullin Plasma Responses During Artificial Gravity on a Human Short-Arm Centrifuge

Frontiers in Physiology, 2019
Galanin and adrenomedullin plasma responses to head-up tilt and lower body negative pressure have been studied previously. However, to what extent short-arm human centrifugation (SAHC) affects these responses is not known.
