Introduction: The clinic usefulness of a diagnostic test is in relationship to the precision with which measures the studied phenomenon. The lack of precision involve the reliability upon causing confounded results of the normal and diseased populations.
Objective: Since the sleep varies in function of the age, to find sleep parameters that fit better to the changes that the aging produces in the sleep.
Material And Methods: Spectral analysis through the Fast Fourier Transformation of the ambulatory EEG of 28 healthy subjects.
Results: Maximum value of power (maximum depth) in a frequency of ended in a point of the sleep goes losing in a way specifies and systematical with the age.
Conclusions: The variance accounted by this parameter is of the 87%, what, being tried to a phenomenon so variable as the sleep, supposes a interesting starting point to be applied to some pathologies in those which is presumed that the slow sleep (to which is attributed a paper in the cerebral restoration) is decreased.

Background: Obstructive sleep apnea (OSA) is frequently associated with increased incidence and mortality of pulmonary hypertension (PH). The immune response contributes to pulmonary artery remodeling and OSA-related diseases. The immunologic factors linked to OSA-induced PH are not well understood.

Background: Accumulating research highlights that exposure to serum brominated flame retardants (BFRs) may elevate health risks. The effects of serum BFRs, both alone and in combination, on obstructive sleep apnea syndrome (OSAS) have not been thoroughly studied. Our main goal was to examine the association between individual and mixtures of serum BFRs and OSAS risk.

Approximately 30-50% of SSc patients develop interstitial lung disease (SSc-ILD), with 30-35% of related deaths attributed to it. Even though men are less likely to develop systemic sclerosis, they have a higher incidence of SSc-ILD than women, and they tend to develop it at a younger age with a higher mortality rate.

Objective: The association between sleep duration, caffeine intake, and bone mineral density (BMD) is not well understood, with previous studies providing controversial results. This study explores the associations among caffeine intake, sleep duration, and BMD.
Methods: Data were sourced from the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018, including 13,457 participants who self-reported sleep duration and caffeine intake, with BMD measured via dual X-ray absorptiometry.
