The objective of this study is to compare the histology and immune cell composition of tonsils from patients with periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome to those from patients with obstructive sleep apnea (OSA). Patients with PFAPA and age-matched controls with OSA who had undergone tonsillectomy at Vanderbilt Children's Hospital were recruited. After informed consent, archival paraffin-embedded, formalin-fixed tonsil tissues were obtained. Sizes of major histologic regions were measured...

Performing hypoxia-reoxygenation cycles in cell culture with a cycle duration accurately reflecting what occurs in obstructive sleep apnea (OSA) patients is a difficult but crucial technical challenge. Our goal was to develop a novel device to expose multiple cell culture dishes to intermittent hypoxia (IH) cycles relevant to OSA with limited gas consumption. With gas flows as low as 200 mL/min, our combination of plate holders with gas-permeable cultureware generates rapid normoxia-hypoxia cycles. Cycles alternating 1 minute at 20% O2 followed by 1 minute at 2% O2 result in pO2 values ranging from 124 to 44mmHg...

The apolipoprotein (APOE) ε4 allele, a well-described genetic risk factor for late-onset Alzheimer disease (AD), is associated with sleep disturbances even in cognitively normal older adults, although it is not clear whether this association is independent of sleep apnea. We sought to extend previous studies by examining whether cognitively normal older adults without self-reported sleep apnea who carry the APOE ε4 allele have altered sleep characteristics compared to noncarriers. Data from N = 36 (APOE ε4 carriers [n = 9], noncarriers [n = 27]) cognitively normal older adults (Clinical Dementia Rating [CDR] scale = 0) without self-reported sleep apnea were used for these analyses...

OBJECTIVE: Severity estimation of obstructive sleep apnea (OSA) is currently based on the apnea-hypopnea index (AHI), which ignores individual breathing cessation event characteristics. Gender differences in the relationship between the breathing cessation event duration and the related desaturation event severity could mean that the severity of OSA is different in males and females despite a similar AHI. The aim of this work was to evaluate gender differences in the severity of peripheral oxygen desaturation events following obstructive apneas or hypopneas...

PURPOSE: Portable respiratory monitor (PRM) has been proposed for pre-diagnosis of obstructive sleep apnea syndrome (OSAS). However, discrepant physiological signal combinations were rarely studied for diagnostic assessment of OSAS. This study was designed to evaluate combination modes of key physiological signals collected by portable sensor modules for OSAS screening in comparison with polysomnography (PSG). METHODS: People with suspected OSAS were submitted to PRM at a sleep laboratory monitoring concurrently with PSG...

Sleep-disordered breathing is a highly prevalent medical condition, which if undiagnosed leads to increased morbidity and mortality, particularly related to increased incidence of cardiovascular events. It is therefore imperative that we identify patient population at high risk for sleep apnea and refer them to the appropriate therapy as early as possible. Up-to-date there is no management guideline specifically geared towards cardiac patients. Thus, we propose a (SAP) Sleep Apnea Pathway to correctly identify and triage these patients to the appropriate therapy...

OBJECTIVE: To explore the relationship between obstructive sleep apnea syndrome (OSAS) and polymorphism in the IL-1β gene. PATIENTS AND METHODS: We recruited 164 OSAS patients to the observation group and 146 healthy people to the control group during the same period. Using RFLP (Restriction Fragment Length Polymorphism), we detected higher G/G and C/C rates on locus 154 of the IL-1β gene in the OSAS patients compared with the control group. RESULTS: Quantitative fluorescence PCR results showed no significant differences in the mRNA expression between the OSAS patients and the healthy people...

PURPOSE: Obstructive sleep apnea (OSA) has been linked to higher rates of perioperative complications. Practice guidelines recommend minimizing opioids in this cohort to reduce complications. However, a paucity of evidence exists relating different levels of opioid prescription to perioperative complications. Our aim was to investigate if different levels of opioid prescription are related to perioperative complication risk in patients with OSA. METHODS: A total of 107,610 OSA patients undergoing total knee or hip arthroplasty between 2006 and 2013 were identified in a nationwide database and divided into subgroups according to the amount of opioids prescribed...

Mandibular distraction osteogenesis (MDO) successfully relieves obstructive sleep apnea in many infants with Robin sequence. Preoperative virtual surgical planning and fabrication of three-dimensionally printed cutting guides may lead to further improvements in the MDO technique and decrease the risk for damage to adjacent structures such as developing teeth and the inferior alveolar nerve. This report presents an algorithm for virtual surgical planning and three-dimensionally printing of cutting guides for MDO in infants with RS...

Obstructive sleep apnea (OSA) is one of the most common sleep disorders. Since aging is a risk factor for OSA development, it is expected that its prevalence will increase with the current increase in life span. In recent years, several studies have shown that OSA potentially contributes to functional decline, mainly prompted by chronic intermittent hypoxia and sleep fragmentation. Here, we propose that OSA might anticipate/aggravate aging by inducing cellular and molecular impairments that characterize the aging process, such as stem cell exhaustion, telomere attrition and epigenetic changes...

Increasing evidence proved that obstructive sleep apnea (OSA) is associated with a variety of diseases, especially cardiovascular diseases. This study systematically reviewed the existing publications to assess the influence of OSA on cardiovascular survival among patients who underwent percutaneous coronary intervention. Eleven eligible publications, including 3,008 participants, were finally evaluated. Eight studies conducted adjustment of risk ratio for potential cardiovascular risk factors, 5 studies defined OSA groups as AHI (apnea hypopnea index) ≥15/hour, whereas the remaining eligible studies used AHI ≥5/hour, AHI ≥10/hour, or AHI ≥30/hour as the criteria...
