PURPOSE: Ferritin is an intracellular iron storage protein and a marker of inflammation. Studies have shown that subjects with obstructive sleep apnea (OSA) have higher levels of circulating pro-inflammatory cytokines, but little is known about the association between ferritin and OSA. The aims of the study were to evaluate serum ferritin (S-Ferritin) levels in OSA patients compared to levels in the general population and also examine the effect of obesity level and treatment with positive airway pressure (PAP) on S-Ferritin levels...

INTRODUCTION: Obstructive sleep apnea (OSA) has been suggested to be a potential contributing factor for nonalcoholic fatty liver disease (NAFLD). Studies on the association between continuous positive airway pressure (CPAP) and NAFLD in OSA patients are limited and controversial. OBJECTIVES: The aim of this study was to assess the relationship between OSA and NAFLD and the effect of CPAP therapy on serum aminotransferase levels in OSA patients. METHODS: A total of 160 consecutive patients who underwent standard polysomnography were enrolled...

Regulatory neuropeptides control and regulate breathing in physiological and pathophysiological conditions. While they have been identified in the neurons of major respiratory areas, they can be active not only at the central level, but also at the periphery via chemoreceptors, vagal afferents, or locally within lungs and airways. Some neuropeptides, such as leptin or substance P, are respiratory stimulants; others, such as neurotensin, produce variable effects on respiration depending on the site of application...

BACKGROUND: Balloon aortic valvuloplasty (BAV) is often utilized as a bridge prior to surgical or transcatheter aortic valve replacement. Chronic kidney disease (CKD) is commonly present in patients with aortic stenosis, however, its association with outcomes following BAV has not been well studied. Accordingly, we sought to assess the impact of CKD on mortality in adults undergoing BAV. METHODS: The Nationwide Inpatient Sample was screened for hospitalizations involving adults undergoing BAV from 2006 to 2012...

PURPOSE: Treatment-emergent central sleep apnea (TE-CSA) is defined as the emergence or persistence of central respiratory events during the initiation of positive airway pressure (PAP) without a back-up rate in obstructive sleep apnea (OSA) patients and after significant resolution of obstructive events. Previous studies have estimated a prevalence from 0.56 to 20.3%. The aim of this study was to establish the prevalence of TE-CSA in a Greek adult population. METHODS: One thousand fifty nine patients with newly diagnosed OSA, who were referred to the Sleep Disorders Center of Evangelismos Hospital of Athens over an 18-month period, were included in this study...

REVIEW
Elliott Vichinsky
Sickle cell disease is now a chronic adult illness characterized by progressive multiorgan failure, particularly involving the brain and kidney. The etiology is multifactorial; it includes hemolysis and nitric oxide deficiency. As patients age, most experience neurologic insult. Twenty-five percent of older adults have had a clinical stroke and at least half of the population have had a silent infarct, cortical atrophy, and neurocognitive impairment. Periodic screening with neuroimaging and neurocognitive testing is recommended...

OBJECTIVES: Depth of sleep within non-rapid-eye-movement (non-REM) stage-2 (N2-depth) varies from being nearly similar to stage-1 to nearly similar to stage-3. Differences in N2-depth are not captured by conventional indices of sleep depth (N1-N3 times, arousal/awakening index) when comparing sleep depth under different conditions. Magnitude of changes in N2-depth in the same individual under different experimental conditions, and the importance of measuring these changes are unknown...

A population of appropriately selected patients does not respond, or does not achieve cure, with hypoglossal nerve stimulation (HGNS). We describe the case of nonresponder whose obstructive sleep apnea (OSA) resolved with the addition of chin strap. After initial placement and titration of HGNS implant, follow-up sleep study demonstrated persistent moderate OSA. Drug-induced sleep endoscopy demonstrated supraglottic collapse with activate neurostimulation. With mouth closure and change of stimulation settings to unipolar from bipolar, the airway collapse and desaturations improved...

Sickle cell disease is one of the most common hereditary hemoglobinopathies worldwide, and its vaso-occlusive and hemolytic crises cause considerable patient morbidity. A growing body of evidence has shown that sleep-disordered breathing, and in particular, obstructive sleep apnea, occurs at high frequency in the sickle cell population, and that there is significant overlap in the underlying pathophysiology of these two conditions. Through a variety of mechanisms including nocturnal hypoxemia and increased oxidative stress, production of pro-inflammatory cytokines, and endothelial dysfunction, sickle cell anemia and sleep-disordered breathing potentiate each other's clinical effects and end-organ complications...

BACKGROUND AND PURPOSE: Intermittent hypoxia causes a persistent increase in sympathetic activity, which progresses to hypertension in chronic conditions such as obstructive sleep apnea (OSA). Pituitary adenylate cyclase activating polypeptide (PACAP) is an excitatory neurotransmitter that causes long-lasting sympathetic excitation. We aimed to determine if intermittent activation of the rostral ventrolateral medulla (RVLM) causes PACAP-mediated elevation of sympathetic nerve activity (sSNA), termed sympathetic long-term facilitation (sLTF)...
