[PMID: 37430029 DOI: 10.1007/s11325-023-02870-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 05/01/2023] [Accepted: 06/07/2023] [Indexed: 07/12/2023]
Abstract
PURPOSE Ischemia-modified albumin (IMA), total oxidant status (TOS), and total antioxidant status (TAS) are biomarkers used to evaluate oxidative stress status in various diseases including obstructive sleep apnea (OSA). In this study, we investigated the effects of disease severity and comorbidity on IMA, TOS and TAS levels in OSA. METHODS Patients with severe OSA (no-comorbidity, one comorbidity, and multiple comorbidities) and mild-moderate OSA (no-comorbidity, one and multiple comorbidities), and healthy controls were included in the study. Polysomnography was applied to all cases and blood samples were taken from each participant at the same time of day. ELISA was used to measure IMA levels in serum samples and colorimetric commercial kits were used to perform TOS and TAS analyses. In addition, routine biochemical analyses were performed on all serum samples. RESULTS A total of 74 patients and 14 healthy controls were enrolled. There was no statistically significant difference between the disease groups according to gender, smoking status, age, body mass index (BMI), HDL, T3, T4, TSH, and B12 (p > 0.05). As the severity of OSA and comorbidities increased, IMA, TOS, apnea-hypopnea index (AHI), desaturation index (T90), cholesterol, LDL, triglyceride, AST, and CRP values increased significantly (p < 0.05). On the other hand, TAS, minimum desaturation, and mean desaturation values decreased significantly (p < 0.05). CONCLUSIONS We concluded that IMA, TOS, and TAS levels may indicate OSA-related oxidative stress, but as the severity of OSA increases and with the presence of comorbidity, IMA and TOS levels may increase and TAS levels decrease. These findings suggest that disease severity and presence/absence of comorbidity should be considered in studies on OSA.

The beneficial effects of green tea on sleep deprivation-induced cognitive deficits in rats: the involvement of hippocampal antioxidant defense. Heliyon 2021; 7:e08336. [PMID: 34820541 PMCID: PMC8601997 DOI: 10.1016/j.heliyon.2021.e08336] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Revised: 08/15/2021] [Accepted: 11/03/2021] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND The weight of evidence suggests that sleep is essential for the processes of memory consolidation and sleep deprivation (SD) impairs the retention of long-term memory in both humans and experimental animals, which is associated with oxidative stress damage within the brain. Green tea polyphenols have revealed carcinogenic, antioxidant, anti-, and anti-mutagenic properties. We aimed to investigate the possible protective effect of green tea extract (GTE) and its main active catechin, epigallocatechin-3-gallate (EGCG), on post-training total sleep deprivation (TSD) -induced spatial memory deficits and oxidative stress profile in the hippocampus of the rat. METHODS Male rats were treated with saline, GTE (100 and 200 mg/kg/day), and EGCG (50 mg/kg/day) intraperitoneally for 21 days and then trained in Morris water maze (MWM) in a single day protocol. Immediately after the end of MWM training, animals were sleep deprived for 6 h by the gentle handling method, and then evaluated for spatial memory. Hippocampal levels of malondialdehyde, (MDA), and thiol was assessed as oxidant and antioxidant markers. RESULTS Spatial memory was impaired in the TSD group and GTE at the dose of 200 mg/kg/day as well as EGCG at the dose of 50 mg/kg/day could reverse the impairment to the saline-treated levels. Despite the unchanged MDA levels, hippocampal total thiol was significantly decreased after TSD and EGCG increased it to the basal levels. CONCLUSION In conclusion, green tea and its main catechin, EGCG, could prevent memory impairments during 6 h of TSD; probably through normalizing the antioxidant thiol defense system which was impaired during TSD.

Abstract
AIM This study aimed to determine the differences in the clinical, demographic and polysomnographic characteristics of OSAS between patients older than and younger than 65 years of age. METHODS Two groups of OSAS patients under 65 years of age and older who underwent PAP treatment in our sleep center were included in the study. Demographic, clinical, and polysomnographic variables of patients were compared as well as the PAP device usage compliance. RESULTS The study was conducted with 183 patients (81 females and 102 males) having the diagnosis of OSAS. The ages of the patients ranged from 37 to 85 years (mean: 58.77 ± 12.59). The incidence of apnea, chest pain, arrhythmia, headache, non-concentration, forgetfulness, psychiatric disorders, motor activity, enuresis, libido and impotence complaints as well as the sedative usage rates and incidence of additional diseases were higher in elderly patients. Apnea hypopnea index, inspiratory positive airway pressure, and expiratory positive airway pressure measurements were significantly higher in the elderly group. The rates of NREM2 (%) and NREM3 (%) were lower in elderly patients. CONCLUSION Many comorbid medical conditions, concomitant drug use, and age-related physiological changes in sleep architecture and circadian rhythm and their effects on sleep should be considered in the elderly sleep.

Abstract
INTRODUCTION We aimed to evaluate plasma thiol and disulphide levels as an additional marker to prostate specific antigen (PSA) in the diagnosis of prostate cancer (PCa). METHODS Between March 2017 and January 2018 prospective study was conducted among patients with PSA levels of 2.5-20 ng/mL without suspicion of malignancy in rectal examination and who underwent prostate needle biopsy. Patients were divided into two groups according to PSA level as 2.5-10 ng/mL (Group 1) and 10.01-20 ng/mL (Group 2). Diagnostic efficacy of thiol, disulphide and PSA levels were measured by ROC analysis. RESULTS A total of 76 patients were included in the study. There were 49 patients in group 1 and 27 patients in group 2. There was no significant difference between two groups in terms of PSA density and prostate size. In Group 1, area under curve (AUC) was higher in PSA than other parameters with statistically significant difference (p<.05). In group 2, AUC of native and total thiol was higher than PSA but there was no statistically significant difference for AUC in parameters. CONCLUSIONS We think that plasma thiol test may be used in diagnosis of prostate cancer while PSA levels between 10 to 20 ng/mL. However, further studies are required.

Abstract
OBJECTIVES Obstructive Sleep apne syndrome is a disease with high morbidity and mortality. The aim of this study was to investigate the conditions affecting the mortality of patients diagnosed with OSAS at six year follow up. METHODS 970 patients who admitted to Sleep laboratory between 2011-2013 were evaluated retrospectively. 74 patients whose mortality data could not be accessed through the system were excluded. The patients who died until April 2019 were compared with the surviving group in terms of demographic, clinical, comorbidities and polysomnographic findings. RESULTS Total 47 patients who died were older, had higher BMI, AHI and ODI values, lower minimum oxygen saturations compared with the survival group (p < .001). In the Cox-hazard regression analysis, BMI (hazard ratio (HR), 1.08; 95% CI, 1.04-1.12), age (1.12, 1.08-1.15), accompanying COPD (2.19, 1.08-4.43), accompanying CAD (2.76, 1.34-5.67) and AHI of >50/h (2.19, 1.19-1.4.05) were reported. CONCLUSION This study showed that OSAS increases the risk of death accompanied by CAD and COPD. It has also been shown that patients with higher AHI (AHI > 50/h) values die more. Therefore, it may be useful to classify the AHI> 50/h group as very severe OSAS instead of severe OSAS.

Abstract
The present study aimed to investigate the frequency of deep venous thrombosis (DVT) among patients with obstructive sleep apnea syndrome (OSAS). Patients who referred the preliminary diagnosis of OSAS were included in this study. D-dimer levels of all patients were measured, and D-dimer (+) patients were evaluated by Doppler USG of the lower-extremity. Mean age of the patient group was 52 ± 12 years and 31.8% (76/239) were women. The rate of D-dimer positivity among severe-OSAS cases (15/85) was significantly higher compared to the rest (13/154) (17.6% and 8.4%, respectively; p = 0.034). The risk of D-dimer positivity was elevated by 2.3 folds in severe-OSAS cases (OR: 2,324, 95% confidence interval: 1.048-5.152). Among 28 D-dimer (+) cases, 4 (14.2%) had DVT as demonstrated by USI of the lower-extremity. All four cases with DVT had severe OSAS. D-dimer was positive in 17.6% (15/85) of all severe OSAS cases. DVT was diagnosed in 4.7% (4/85) of severe-OSAS cases. DVT frequency was 26.6% (4/15) in D-dimer (+) severe-OSAS. Findings of this study indicate that severe-OSAS can be a significant risk factor for DVT. Additionally, data obtained in this study underline the benefits of questioning severe-OSAS patients with respect to DVT symptoms, investigating D-dimer levels and evaluating D-dimer (+) severe-OSAS cases for DVT prophylaxis.

Abstract
AIM Obstructive sleep apnea syndrome (OSAS) patients show multiple physiological deficits and several neuropsychological comorbidities. The aim of this study was to investigate the eating attitudes in OSAS patients. MATERIAL AND METHODS Polysomnography records of 157 were performed. Eating Attitudes Test (EAT), Beck Depression Inventory (BDI), and the Beck Anxiety Inventory (BAI) were applied to all participants. RESULTS The mean age of the 157 individuals included in the study was 47.2 ± 11.4 (18-76) years and 36% (n = 56) of the individuals were female and 64% (n = 101) were male. When the patients were ranked according to the severity of OSAS, 38.2% (n = 60) were severe, 20.4% (n = 32) were moderate, 24.2% (n = 38) were mild, and 17.2% (n = 27) were OSAS negative. There was a significant difference in terms of the age-and-BMI-adjusted EAT score according to OSAS severity (p = .042). There was a significant difference in the age-and-BMI-adjusted value of the EAT according to the presence of OSAS (p = .011). After controlling age and BMI, no significant correlation was found between the EAT and the BDI (r = 0.012, p = .890) in patients with OSAS while there was a significant positive correlation EAT and the BAI (r = 0.177, p = .046). CONCLUSIONS Considering the association of OSAS with psychiatric disorders, the presence of eating disorders (EDs) becomes an important and special topic. Treatment of patients with OSAS should not only aim to improve the patient's sleep apnea, but also to improve the patient's quality of life by evaluating the patient's psychological and physical functions.

Abstract
OBJECTIVE We aimed to determine the clinical, radiological and laboratory findings that may indicate poor prognosis in severe community acquired pneumonia (CAP) requiring intensified care to reduce the risk of death. METHODS The medical histories, demographic characteristics and laboratory values of over 65 years old patients admitted to the intensive care unit (ICU) and diagnosed with CAP were recorded. RESULTS Total of 86 patients were included in the study. Among those patients 39 were discharged from the ICU with health but 47 were expired. Diastolic blood pressure was significantly lower in expired patients (p = 0.044). In multivariate analysis, older age (>78 years) (p = 0.004), at admission elevated blood glucose (>108 mg/dL) levels (p = 0.048), decreased serum albumin (<3.5 g/dL) levels (p = 0.043), elevated serum procalcitonin levels (>0.63 μg/L) (p = 0.034) and in blood gas analysis decreased pH (<7.35) (p = 0.042)and increased lactate (>2mmol/L) (p = 0.001) were the significant risk factors for in-ICU mortality. CONCLUSIONS At old age, blood glucose and procalcitonin levels increased at the time of admission, serum albumin levels decreased, pH decreased in blood gas analysis and lactate levels increased, and significant mortality determinants in CAP patients over 65 years of age who applied to the intensive care unit.

Abstract
OBJECTIVE To examine dynamic thiol/disulphide homeostasis metrics as a novel risk factor of oxidative stress in patients with peripheral arterial disease. METHODS One hundred patients with lower extremity peripheral arterial disease (a study group) and 100 control subjects were included in this prospective case-control study. Participants' baseline clinical characteristics and laboratory data including some oxidant/antioxidant status parameters such as albumin, ferroxidase and myeloperoxidase, and thiol/disulphide homeostasis parameters such as native thiol, total thiol and disulphide, as well as native thiol/total thiol, disulphide/native thiol and disulphide/total thiol ratios were all recorded and then compared between the groups. RESULTS Mean albumin and ferroxidase, and median myeloperoxidase levels were found to be significantly higher in patients with the peripheral arterial disease than in control group (p = 0.045, p = 0.000 and p = 0.000, respectively). Mean native thiol and total thiol, and median disulphide levels were found to be significantly lower in the study group as compared with the control group (p = 0.000, p = 0.000 and p = 0.037, respectively). According to the results of logistic regression analysis, systolic blood pressure, ferroxidase and myeloperoxidase levels were detected to be the independent predictors of peripheral arterial disease. CONCLUSION Our report is the first one in the literature investigating dynamic thiol/disulphide homeostasis metrics as a novel risk factor of oxidative stress in peripheral arterial disease. Dynamic thiol/disulphide homeostasis metrics may be used as a valuable risk factor of oxidative stress in patients with the peripheral arterial disease since it is readily available, easily calculated and relatively cheap.

Abstract
Aim: The aim of this study was to compare hematological parameters with the mean obstructive apnea duration (MOAD), mean mixed apnea duration (MMAD), mean central apnea duration (MCAD), mean total apnea duration (MTAD) and mean hypopnea duration (MHD), and blood oxygenation, other polysomnographic sleep parameters in patients with severe OSA.Material and methods: A retrospective study included 120 patients with severe OSA. The correlations between the hematological parameters with MOAD, MMAD, MCAD, MTAD, MHD, and blood oxygenation, other polysomnographic sleep parameters were analyzed.Results: There was a positive correlation between hgb with MOAD, MMAD, MTAD MCAD, MHD; mean oxygen desaturation, and the number of desaturation (≥5%). Also, hgb associated negatively with N1 sleep, WASO (wake time after sleep onset) and positively with REM, N2 sleep, total sleep time, and sleep efficiency. RDW and MOAD, MTAD, MHD were negatively related. Also, RDW related positively with sleep latency, WASO, and N1 sleep; negatively with sleep efficiency and REM sleep. There was no relationship between duration of respiratory events with NLR, PRL, and MPV.Conclusions: Hematological parameters, especially hgb and RDW, can be used to assess the severity of the disease in severe OSA patients in addition to AHI.

Abstract
Background: There are few studies showing that the increase in particulate matters less than 10 μm (PM10) values increases the apnea-hypopnea index (AHI). We aimed to investigate relationship between air quality parameters and the seasons with the AHI.Methods: This was a retrospective study that included 500 adults. Polysomnography (PSG) was performed on all patients. Oxygen saturation, air temperature, relative humidity, and PM10 values were recorded in Düzce for every year. The parameters of the national air quality network and sleep parameters of 500 individuals hospitalized between 2015 and 2017 were checked.Results: A total of 500 patients were included in the study, of whom 316 (63.2%) were male and 184 (36.8%) were female. While the AHI value of patients who presented during 2016 was 27.5, it had significantly declined to 20.2 in 2017 (p = .024). A significant decline was observed in AHI values of OSA patients from 2016 to 2017 (p = .043). A significant positive correlation was observed between REM-related AHI and relative humidity (r = 0.183, p = .002). Conclusions: This study showed a clear relationship between AHI and PM10 during winter when air pollution parameters are high in the region. PM10 emerged as a parameter that substantially increases the relative risk for OSA.
