Background: Apnea of prematurity often occurs during and following caffeine therapy. We hypothesized that number of apnea events would be impacted by adjustments in caffeine therapy. Materials and Methods: An automated algorithm was used in all infants ≤32 weeks gestation admitted to a level IV

This study was designed to examine the effects of hypoxia, acidosis, glucose-free medium and their combination on contraction and sarcoplasmic reticulum (SR) function in rat ventricular trabeculae. The isometric twitch tension was measured during superfusion with hypoxic (PO2 less than 30 mmHg),
INTERMITTENT HYPOXIA ALTERS DOSE DEPENDENT CAFFEINE EFFECTS ON RENAL PROSTANOIDS AND RECEPTORS IN NEONATAL RATS.

Caffeine, one of the most commonly prescribed drugs in preterm neonates, is given in standard or suprapharmacologic doses. Although known as a diuretic, its effects in the neonatal kidneys are not well studied. We tested the hypothesis that neonatal intermittent hypoxia (IH) and high caffeine doses
Alteration of carotid body chemoreflexes after neonatal intermittent hypoxia and caffeine treatment in rat pups.

In human neonates, caffeine therapy for apnoea of prematurity, especially when associated with hypoxemia, is maintained for several weeks after birth. In the present study, we used newborn rats and whole-body plethysmography to test whether chronic exposure to neonatal caffeine treatment (NCT),
Maternal caffeine ingestion during gestation and lactation influences respiratory adaptation to acute alveolar hypoxia in newborn rats and adenosine A2A and GABA A receptor mRNA transcription.

Caffeine is a widely used psychostimulant freely crossing the placental barrier. At the doses usually absorbed, it acts as an antagonist of both A1 and A2A adenosine receptors. Pregnant women are generally not advised to limit their caffeine consumption and thus expose their progeny to the drug
Epileptogenic action of caffeine during anoxia in the neonatal rat hippocampus.

Excessive maternal caffeine consumption can lead to fetal and neonatal pathology, but the underlying mechanisms have not been determined. Here, we report that low doses of caffeine generate seizures when applied in conjunction with brief anoxic episodes in the hippocampus of neonatal rats in vitro.

OBJECTIVE
To investigate the effects of caffeine on performance, neuromuscular fatigue and perception of effort during high-intensity cycling exercise in moderate hypoxia.
METHODS
Seven adult male participants firstly underwent an incremental exercise test on a cycle ergometer in conditions of acute

The respiratory stimulant caffeine is the most frequently used xanthine (theophylline or aminophylline) for the treatment of apnea in premature infants. It decreases but does not eliminate apnea. In most cases such decreases is insufficient to prevent the use of artificial ventilation. Progesterone
Enhancement of the breathing frequency response to hypoxia by neonatal caffeine treatment in adult male rats: the role of testosterone.

Caffeine is a common treatment for apnea of prematurity. Although relatively safe, little is known about the potential long-term effects of this treatment on respiratory control development. We previously showed that adult male (but not female) rats previously subjected to neonatal caffeine

Purinergic signaling is linked to neurodegenerative and proinflammatory damage during pathological conditions such as hypoxia, but involvement of this pathway in brain damage in fish exposed to environmental hypoxia remains unknown, and we propose dietary supplementation with caffeine in order to
Maternal hypoxia and caffeine exposure depress fetal cardiovascular function during primary organogenesis.

OBJECTIVE
Hypoxia is known to influence cardiovascular (CV) function, in part, through adenosine receptor activation. We have shown in a mouse model that during primary cardiac morphogenesis, acute maternal hypoxia negatively affects fetal heart rate, and recurrent maternal caffeine exposure reduces

Hypothermia during calcium-free perfusion of hearts protects them from injury caused by subsequent calcium repletion at 37 C (calcium paradox). Injury to calcium-free hearts is also associated with contracture caused by anoxia, 2,4-dinitrophenol (DNP), or caffeine. This study was done for the
Chronic caffeine intake in adult rat inhibits carotid body sensitization produced by chronic sustained hypoxia but maintains intact chemoreflex output.

Sustained hypoxia produces a carotid body (CB) sensitization, known as acclimatization, which leads to an increase in carotid sinus nerve (CSN) activity and ensuing hyperventilation greater than expected from the prevailing partial pressure of oxygen. Whether sustained hypoxia is physiological (high
Caffeine stimulates ventilation in athletes with exercise-induced hypoxemia.

OBJECTIVE
Many athletes with exercise-induced hypoxemia (EIH) show an insufficient ventilatory response to exercise and low resting ventilatory responsiveness. The purpose of this project was to determine whether a moderate dosage of caffeine, a common ventilatory stimulant, could augment resting

The effect of oral caffeine on resting ventilation (VE), ventilatory responsiveness to progressive hyperoxic hypercapnia (HCVR), isocapnic hypoxia (HVR), and moderate exercise (EVR) below the anaerobic threshold (AT) was examined in seven healthy adults. Ventilatory responses were measured under
