Maternal behavior in basic science: translational research and clinical applicability

Gabriel Natan Pires, Sergio Tufik, Márcia Giovenardi, Monica Levy Andersen

Clinical aspects of the mother-infant relationship and related issues are well studied and very relevant to medical practice. Nevertheless, some approaches in this context cannot plausibly be investigated in humans due to their ethical implications and to the potential harm to the mother’s and child’s health. Studies on maternal behavior in animals have evident importance to some clinical fields, such as psychiatry and psychology, particularly considering topics, including mother-infant relationship, postpartum depression, cognitive and behavioral development of children, and associated […]

Relationship between sleep deprivation and anxiety: experimental research perspective

Gabriel Natan Pires, Sergio Tufik, Monica Levy Andersen

Sleep deprivation is a condition that is more and more observed in modern society bringing various neurobehavioral effects, being anxious states one of the main problems. Many studies have successfully demonstrated the relationship between sleep deprivation and anxiety in clinical research. As to basic experimentation, various models have been efficiently used in order to evaluate an anxious behavior. However, the same efficacy is not found on basic studies that deal with the relationship between paradoxical sleep and anxiety. The great […]

ABSTRACTObjective:To assess the prevalence of ventricular arrhythmias induced by exercise in a population with sleep disorders and to analyze the triggering factors.Methods:Patients were consecutively selected from the database of the Sleep Clinic of Universidade Federal de São Paulo. All subjects were submitted to basal polysomnography, blood sample collection, physical examination, 12-lead ECG, spirometry, cardiorespiratory exercise study on a treadmill, and echocardiogram. The Control Group was matched for age and gender.Results:A total of 312 patients were analyzed. Exercise-induced ventricular arrhythmia was […]
