background and objective: higher concentration of systemic inflammatory markers is reported in patients with obstructive sleep apnea (osa). levels of inflammatory markers may be associated with severity of osa. objective of this study was to evaluate the correlation between level of inflammation markers and osa severity. materials and methods: fifty six patients with symptoms and signs of osa f...

BACKGROUND Obstructive sleep apnea (OSA) is associated with an increase in the prevalence and incidence of hypertension and cardiovascular diseases. Data about epidemiological characteristics of OSA in Chinese hypertensive populations is limited. METHODS Hypertensive subjects without a prior diagnosis of OSA were recruited, and the apnea-hyponea index (AHI) was assessed by polysomnography. Co...

BACKGROUND Prospective studies have identified obstructive sleep apnea (OSA) as a risk factor for increased overall cancer incidence and mortality. The potential role of OSA in the risk or progression of specific cancers is not well known. We hypothesized that pathological differences in pancreatic cancers from OSA cases compared to non-OSA cases would implicate OSA in pancreatic cancer progres...

Obstructive sleep apnea (OSA) is a highly prevalent condition that is associated with significant neurobehavioral impairments. Cognitive abnormalities identified in individuals with OSA include impaired verbal memory, planning, reasoning, vigilance, and mood. Therapy for OSA improves some but not all neurobehavioral outcomes, supporting a direct role for OSA in brain dysfunction and raising the...

BACKGROUND Obstructive sleep apnea (OSA) is a prevalent disorder causing hypertension. Endothelial dysfunction appears to underlie development of hypertension. It is not known whether hypoxia during sleep is necessarily the prerequisite process for endothelial dysfunction and hypertension in OSA. We therefore examined the relationship between endothelial-dependent vasodilatory capacity, hypoxia...

OBJECTIVES. To estimate the soft tissue determined individual features of the upper airway sagittal size which may predispose the patient to snoring and OSA and to find whether there is any relationship between the patient's body-mass index (BMI) and the severity of OSA. MATERIAL AND METHODS. 58 consecutive patients with a mean age of 33.4 years were surgically treated for snoring and OSA. Befo...

Obstructive sleep apnea (OSA) is a common medical condition that occurs in a considerable percentage of the population. Substantial evidence shows that patients with OSA have an increased incidence of hypertension compared with individuals without OSA, and that OSA is a risk factor for the development of hypertension. It is established that OSA may be implicated in stroke and transient ischemic...

In order to improve the ability of starch absorb menthone, corn was modified by enzymatic treatment (amyloglucosidase and ?-amylase) combined with octenyl succinic anhydride (OSA) esterification. The oil absorption rate followed OSA (P-OSA) reached 101.33%, whereas that samples reverse action sequences (OSA-P) only 59.67%. degree substitution OSA-P also generally lower than P-OSA. At high addit...

Obstructive sleep apnea (OSA) is highly associated with hypertension. However, the correlation between hypertension and OSA at different levels of severity and the influence of gender on that correlation are unclear. A total of 996 patients (776 males and 190 females) with OSA were recruited. The influence of gender on the correlation between hypertension and OSA at different stratifications of...
