Reactive oxygen species produced either endogenously or exogenously can attack lipids, proteins and DNA in human cells cause potentially deleterious consequences. In recent years, their role the pathogenesis of lung cancer preventive effect antioxidants have been studied extensively. this study, our aim was to investigate levels 8-hydroxy-2'-deoxyguanosine (8OHdG) malondialdehyde as a marker for effects reactive on antioxidant vitamins correlations between these oxidative stress markers...
Objective: To investigate the effect of one year continuous positive airway pressure (CPAP) treatment on metabolic syndrome (MS) prevalence and components in patients diagnosed with both obstructive sleep apnea (OSAS) syndrome.Methods: This was a single center, observational prospective cohort study. 38 who were OSAS after polysomnographic analysis laboratory MS according to National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guideline underwent CPAP followed for...
The objective of this study was to evaluate left atrial (LA) function in patients with obstructive sleep apnoea (OSA) receiving continuous positive airway pressure therapy (CPAP), incorporating two-dimensional speckle-tracking echocardiography (2D-STE).Forty-five control and 117 OSA were enrolled the study. They categorized into mild, moderate severe groups according apnoea-hypopnoea index (AHI). All underwent conventional 2D-STE. Forty-three AHI greater than 20 receive CPAP for 24 weeks....
This study was conducted to determine the critical partial oxygen pressure (pO2) value that would impair hearing function by evaluating effects of hypoxia on in subjects diagnosed with chronic obstructive pulmonary disease (CPOD).The included 25 male and 5 female patients referred our clinic who were COPD, according spirometry PaO2 values, did not show pathology upon autoscopic examination. The control group consisted 14 16 had no lung same age range as COPD group.A statistically significant...
Association of obstructive sleep apnea with homocystein, nitric oxide and total antioxidant capacity levels in patients or without coronary artery disease Introduction: Obstructive (OSA) is associated cardiovascular morbidity mortality.Deficiency
In the present study, "obstructive sleep apnea (OSA) patients" and "non-OSA were classified into two groups using with synchronic heart rate variability (HRV) series obtained from electrocardiography (ECG) photoplethysmography (PPG) signals. A linear synchronization method called cross power spectrum density (CPSD), commonly used on HRV series, was performed to obtain high-quality signal features discriminate OSA controls. To classify simultaneous ECG PPG signals recorded non-OSA patients,...
Amaç: Obstrüktif Uyku Apne sendromu (OSAS) hastalarında fiziksel aktivite (PA) katılımını etkileyen faktörleri inceleyen araştırmalara ihtiyaç vardır.Bu çalışmanın amacı, OSAS'li hastalarda PA düzeyi ile gündüz uyku hali, yorgunluk algısı, yaşam kalitesi ve psikolojik durum arasındaki ilişkiyi araştırmaktır.Gereç Yöntem: Bu kesitsel çalışma, 30-60 yaşları arasında 38 hastayı kapsamaktadır.PA seviyesi, Uluslararası Fiziksel Aktivite Anketinin (IPAQ) Türkçe versiyonu kullanılarak...
The purpose of this study was to determine whether there is a correlation between CPAP usage and corneal thickness in patients with sleep disordered breathing. Full-night polysomnography (PSG) recordings were collected. Ten had undergone PSG continuous positive airway pressure (CPAP), seven without CPAP. We measured by ultrasonic pachymeter before ten minutes after waking. also visual acuity routine ophthalmologic eye chart sleep. asked fill out post-sleep questionnaire get their subjective...
YKL-40 [chitinase-3 like-1 (CHI3L1)] is a glycoprotein, has been implicated in inflammation, endothelial dysfunction, tissue remodelling and it accepted as noninvasive prognostic biomarker for inflammation. In this study, we aimed to underline usability of serum an inflammatory patients with obstructive sleep apnea syndrome (OSAS).Two groups OSAS [Group I: Mild-moderate OSAS, n:43; median apnea-hypopnea index: AHI, /hour:18], Group II: Severe n: 25; AHI:41.6] healthy control group [n:25,...
In this study, to obtain high quality signal features in discriminating the Central Sleep Apnea (CSA) and Obstructive (OSA) from controls, both linear nonlinear EEG synchronization methods so called Coherence Function (CF) Mutual Information (MI) are performed. For purpose, sleep series data collected patients healthy volunteers classified by using a well known widely used Feed-Forward Neural Network (FFNN) with respect synchronic activities between C3 C4 recordings. The results show that...
Amaç: Pulmoner tromboemboli (PTE) mortalite ve morbiditesi yüksek bir hastalıktır.Tedavi edilmemiş PTE'de %30'dur.Bu çalışmada amacımız kliniğimizde tetkik tedavileri yapılmış olan embolili hastaları; semptomları, risk faktörleri, fizik muayene, laboratuvar radyolojik bulguları açısından tekrar değerlendirmektir
Amaç: Bu çalışmada, uvulopalatal flap cerrahisinin kantitatif analizi için sinyal işleme tekniklerine dayanan yeni bir metodoloji önerilmektedir
Is Hepcidin a Good Marker for Inflammation in Obstructive Sleep Apnea Syndrome (OSAS) Patients?Amaç: Obstrüktif Uyku Apne sendromu (OUAS) uykuda defalarca üst solunum yolunun tıkanması ile karakterize klinik bir sendrom olup, kronik aralıklı hipoksi gelişimi sonucu dokuda enflamasyon oluşumuna neden
Objective: Obstructive sleep apnea (OSA) is associated with increased risk of left atrial (LA) dysfunction. Although previous echocardiographic studies have demonstrated improved LA function in patients OSA receiving continuous positive airway pressure (CPAP) device, a long-term prospective study incorporating two-dimensional speckle tracking echocardiography (2D-STE) has not been evaluated to date.
ÖzObjective: The purpose of the study is to evaluate risks atrial and ventricular tachyarrhythmia risk right dilatation by using P wave amplitude (Pda) measurement, in patients with Obstructive Sleep Apnea syndrome (OSAS) parameters dispersion (Pd) QT interval (QTc) accepted noninvasive indicators for tachyarrhythmia.Materials Methods: Patients who had applied our clinic's sleep laboratory pre-diognosis OSAS were evaluated.Two hundred twenty five cases included met criteria acceptance...
