Publication Assessment of the risk of obstructive sleep apnoea syndrome among healthcare workers(Turkish Assoc Tuberculosis & Thorax, 2019-01-01) Güçlü, Özge Aydın; İntepe, Yavuz Selim; Acican, Turan; Arslan, Sertaç; Sertoğullarından, Bünyamin; Karadağ, Mehmet; KARADAĞ, MEHMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi.; 0000-0002-9027-1132; AAG-8744-2021Introduction: Sleep deprivation is known to increase the risks for workplace accidents, neuro-behavioural symptoms and reduced quality of life. Shift work leads to sleep related problems, such as sleep deprivation, poor sleep quality and daytime sleepiness. The purpose of our study is to assess snoring prevalence and obstructive sleep apnoea risk among healthcare workers (HCWs) by using the Berlin Questionnaire.Materials and Methods: HCWs employed at different centres that agreed to take part in this study were enrolled. Employing the Berlin Questionnaire, demographic characteristics, smoking histories, comorbidities, on-call shifts, number of on-call shifts and sleep durations of the participants were surveyed.Results: 604 HCWs including specialist, nurse, junior doctor, medical student, clinical academic, health technician and hospital staff were enrolled in this study. In terms of sleep apnoea, 92 (15.1%) participants were identified as high-risk and 512 (84.8%) as low-risk according to the findings of the questionnaire. When the two groups identified as high and low risk for sleep apnoea according to the Berlin Questionnaire were compared, significant differences were found between the two groups in terms of age, sex, height, weight, BMI value and hypertension (p< 0.001 for all variables). Multivariate logistic regression analysis has shown that on-call shifts (OR=0.199, CI=0.053-0.747, p=0.017) are negative associated with sleep apnoea risk.Conclusion: With extended working hours and on-call shifts increasing the risk of sleep disorders among HCWs, surveys designed for screening can be used to identify the prospective cases in this population for further examination.Publication Associated factors with short-term mortality in pulmonary thromboembolism patients(European Respiratory, 2015-09-01) Çetinoğlu, Ezgi Demirdöğen; Dilektaşlı, Aslı Görek; Güçlü, Özge Aydın; Özkaya, Güven; Coşkun, Funda; Ursavaş, Ahmet; Karadağ, Mehmet; Çetinoğlu, Ezgi Demirdöğen; GÖREK DİLEKTAŞLI, ASLI; AYDIN GÜÇLÜ, ÖZGE; ÖZKAYA, GÜVEN; COŞKUN, NECMİYE FUNDA; URSAVAŞ, AHMET; KARADAĞ, MEHMET; Uludağ Üniversitesi/Tıp Fakültesi/Göğüs Hastalıkları Anabilim Dalı; Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı; 0000-0002-7400-9089; 0000-0001-7099-9647; 0000-0003-1005-3205; 0000-0003-0297-846X; 0000-0003-3604-8826; 0000-0002-9027-1132; JPK-7012-2023; AAG-8744-2021; AAI-3169-2021; AAD-1271-2019; A-4421-2016; AAG-9930-2019; AAH-9812-2021; DTT-7416-2022Publication Association between burnout, anxiety and insomnia in healthcare workers: A cross-sectional study burnout, anxiety and insomnia in healthcare workers(Routledge Journals, Taylor & Francis, 2021-01-23) Aydin Guclu, Ozge; Akkoyunlu, Muhammed Emin; Acican, Turan; Sertogullarindan, Bunyamin; Kirbas, Gokhan; Selimoglu Sen, Hatice; Lakadamyali, Huseyin; Intepe, Yavuz Selim; Arslan, Sertac; Firat Gursoy, Sibel; Kaya, Akin; Karadağ, Mehmet; KARADAĞ, MEHMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi.; 0000-0003-1005-3205; 0000-0002-9027-1132; 0000-0002-2866-6686; 0000-0002-5697-5291; JSK-7543-2023; AAP-7682-2020; AAG-8744-2021; AAG-9930-2019; D-5756-2018; W-1764-2017All healthcare workers (HCWs) encounter stress during in their working lives, and are constantly exposed to adverse conditions. The present study evaluates the relationship between burnout syndrome, anxiety levels and insomnia severity among healthcare workers, who mostly work in shifts. The Maslach Burnout Inventory, the Insomnia Severity Index and the Beck Anxiety Inventory were used to measure burnout, insomnia severity and anxiety status, respectively. This cross sectional study included a total of 1,011 HCWs and 679 (67.2%) of the study respondents were women. The respondents were aged 20-72, with a mean age of 35.67 +/- 8.61 years. Fifty-eight percent (n = 589) of the participants were rotating shift workers. Working on-call led to a significant difference in all burnout parameters (for each, <0.001). Age and on-call duty were seen to lead to a significant difference in the severity of insomnia (p = 0.028, p < 0.001, respectively). The total ISI score was found to be statistically significant positively correlated with the MBI subscales and the total BAI score (for each, <0.001). An increased awareness of the impact of sleep deprivation, burnout and anxiety among HCWs and meaningful interventions promoting change within the healthcare system are needed.Publication Association of fatigue with mental well-being, quality of life and exercise capacity in sarcoidosis: A case-control comparision(Amer, 2015-01-01) Dilektaşlı, Aslı Görek; Çetinoğlu, E.

Although the STOP-BANG questionnaire is an attractive screening tool because of high sensitivity, it lacks power in specificity. The aim of the present study was to evaluate and compare the diagnostic accuracy of standard STOP-BANG and a modified STOP-BANG questionnaire, using national cut-off values for neck circumference that determined OSA, in a sleep center population.MATERIALS AND METHODS: One hundred eighty-five participants who were referred to the sleep-disordered breathing clinic were consecutively enrolled. We used 40 cm and 36 cm as the cut-off values for neck circumference, thus scoring patients accordingly and creating a modified STOP-BANG score with national anthropometric obesity indexes.RESULTS: The median neck circumferences were 41 (39-44) cm, 40 (37-42) cm, and 43 (40-45) cm for total population, female gender, and male gender, respectively. The mean STOP-BANG score was 4.5 +/- 1.5, and the mean modified STOP-BANG score was 4.9 +/- 1.5. Discrimination of OSA measured by area under the curve for both questionnaires is comparable (p>0.05). Sensitivity to define OSA (apnea-hypopnea index (AHI)>= 1.5) was 92.2% and 93.8% for original and modified STOP-BANG questionnaire, respectively. Sensitivity for moderate (AHI >= 15) and severe OSA (AHI >= 30) was identical for both questionnaires.CONCLUSION: The STOP-BANG questionnaire has an excellent sensitivity, but modest specificity and adding national obesity indexes for neck circumference achieved similar results in terms of sensitivity and specificity with the original questionnaire.Publication Did the smokers level of knowledge on copd changed in the last decade?

Methods: Between January 2014 and September 2018, epidermal growth factor receptor (EGFR), anaplastic lymphoma receptor tyrosine kinase (ALK), and c-ros oncogene 1 receptor tyrosine kinase gene (ROS1) alterations, demographic characteristics, asbestos exposure, and asbestos-related radiological findings of 1904 patients with lung adenocarcinoma were recorded. Results: The frequencies of EGFR mutations, ALK, and ROS1 rearrangements were 14.5%, 3.7%, and 0.9%, respectively. The rates of EGFR mutations and ALK rearrangements were more frequent in asbestos exposed non-smokers (48.7% and 9%, respectively). EGFR mutation rate was correlated to female gender and not-smoking, ALK rearrangement rate was correlated to younger age, not-smoking, and a history of asbestos exposure. Conclusions: The higher rate of ALK rearrangements in asbestos-exposed lung adenocarcinoma cases shows that asbestos exposure may most likely cause genetic alterations that drive pulmonary adenocarcinogenesis.Publication Evaluation of asthma awareness among teachers in Bursa(Turkish Assoc Tuberculosis & Thorax, 2018-01-01) Aydın Güçlü, Özge; Karadağ, Mehmet; KARADAĞ, MEHMET; Demirdöğen Çetinoğlu, Ezgi; DEMİRDÖĞEN, EZGİ; Ceren, Aslı Macunluoğlu; Ediger, Dane; EDİGER, DANE; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/İmmunoloji Anabilim Dalı.; 0000-0002-9027-1132; 0000-0002-2954-4293; AAG-9930-2019; AAG-8744-2021; AAE-9142-2019Introduction: The purpose of this study was to elucidate the asthma knowledge level of primary-secondary school teachers in Bursa, and factors associated with this subject.Materials and Methods: In our study 1812 teachers from 64 randomly selected primary schools in Bursa were included.Results: It was known by the vast majority of participants that asthma symptoms, asthma is not a contagious disease and may be familial, medications taken by inhalation. It was known by 64.1% of the teachers that asthmatic children do not mind doing sports. Approximately one of the two teachers knew that the medication were not addictive.Conclusion: The knowledge level of the teachers was related to female gender and age. We think that an asthma education program is needed for Turkish teachers to increase their understanding about what asthma is, its impact and how to meet the needs of a child with asthma to achieve improved wellbeing and school attendance.Publication Evaluation of fibrinogen levels in patients with obstructive sleep apnea syndrome(Wiley, 2013-11-01) Çetinoğlu, Ezgi Demirdoğen; Ursavaş, Ahmet; Karadağ, Mehmet; Coşkun, Funda; Ediger, Dane; Uzaslan, Esra; Ege, Ercüment; Gözü, Oktay; Çetinoğlu, Ezgi Demirdoğen; URSAVAŞ, AHMET; KARADAĞ, MEHMET; COŞKUN, NECMİYE FUNDA; EDİGER, DANE; UZASLAN, AYŞE ESRA; Ege, Ercüment; Gözü, Oktay; Uludağ Üniversitesi/Tıp Fakültesi/Göğüs Hastalıkları Anabilim Dalı.; 0000-0002-7400-9089; 0000-0002-9027-1132; 0000-0003-3604-8826; 0000-0002-2954-4293; AAI-3169-2021; AAD-1271-2019; AAG-8744-2021; JPK-7012-2023; AAE-9142-2019; AAH-9812-2021; CDI-1977-2022; CPF-5844-2022; JLC-5863-2023Publication Frailty: An indicator for poor outcomes among in-hospital pulmonology patients(European Respiratory Soc Journals, 2021-09-05) Öztürk, Nilüfer Aylin Acet; Dilektaşlı, Aslı Görek; Güçlü, Özge Aydın; Ursavaş, Ahmet; Demirdoğen, Ezgi; Coşkun, Funda; Uzaslan, Esra; Karadağ, Mehmet; ACET ÖZTÜRK, NİLÜFER AYLİN; GÖREK DİLEKTAŞLI, ASLI; AYDIN GÜÇLÜ, ÖZGE; URSAVAŞ, AHMET; DEMİRDÖĞEN, EZGİ; COŞKUN, NECMİYE FUNDA; UZASLAN, AYŞE ESRA; KARADAĞ, MEHMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Göğüs Hastalıkları Anabilim Dalı.; 0000-0002-6375-1472; 0000-0003-1005-3205; 0000-0002-7400-9089; 0000-0003-3604-8826; 0000-0002-9027-1132; AAI-3169-2021; JPK-7012-2023; AAG-8744-2021; AAD-1271-2019; Z-1424-2019; CNP-1063-2022; AAG-9930-2019; CDI-1977-2022Publication Il-21: A potential biomarker for diagnosis and predicting prognosis in covid-19 patients(European Respiratory Society Journals, 2021-09-05) Öztürk, Nilüfer Aylin Acet; Ursavaş, Ahmet; Dilektaşlı, Aslı Görek; Demirdöğen, Ezgi; Coşkun, Funda; Ediger, Dane; Uzaslan, Esra; Yöyen-Ermiş, Diğdem; Karaca, Mert; Terzi, Orkun; Bayram, Merve; Ömer, Dilara; Yiğitliler, Büşra; Yurttaş, Ahmet; Maharramov, Shahriyar; Çelik, Gamze; Oral, Barbaros; Karadağ, Mehmet; ACET ÖZTÜRK, NİLÜFER AYLİN; URSAVAŞ, AHMET; GÖREK DİLEKTAŞLI, ASLI; DEMİRDÖĞEN, EZGİ; COŞKUN, NECMİYE FUNDA; EDİGER, DANE; UZASLAN, AYŞE ESRA; YÖYEN ERMİŞ, DİĞDEM; KARACA, MERT; TERZİ, ORKUN ERAY; BAYRAM, MERVE; ÖMER TOPÇU, DİLARA; YURTTAŞ, AHMET; ORAL, HALUK BARBAROS; KARADAĞ, MEHMET; MAHARRAMOV, SHAHRİYAR; YAZICI, GAMZE; Bursa Uludağ Üniversitesi/Tıp Fakültesi.; 0000-0002-6375-1472; 0000-0002-7400-9089; 0000-0003-3604-8826; 0000-0002-2954-4293; 0000-0001-5871-8769; 0000-0002-9027-1132; AAG-8744-2021; JPK-7012-2023; AAH-3888-2021; AAE-9142-2019; AAI-3169-2021; AAD-1271-2019Publication Improvements in functional exercise performance at six months following bariatric surgery, a prospective cohort study(Amer, 2018-01-01) Dilektaşlı, Aslı Görek; Dilektasli, E.; Coşkun, Funda; Karadağ, Mehmet; GÖREK DİLEKTAŞLI, ASLI; COŞKUN, NECMİYE FUNDA; KARADAĞ, MEHMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi; 0000-0003-3604-8826; 0000-0002-9027-1132; AAD-1271-2019; AAG-8744-2021; DTT-7416-2022Publication Interleukin-21: A potential biomarker for diagnosis and predicting prognosis in covid-19 patients(Tubitak Scientific & Technological Research Council Turkey, 2021-01-01) ACET ÖZTÜRK, NİLÜFER AYLİN; URSAVAŞ, AHMET; GÖREK DİLEKTAŞLI, ASLI; DEMİRDÖĞEN, EZGİ; COŞKUN, NECMİYE FUNDA; EDİGER, DANE; UZASLAN, AYŞE ESRA; YÖYEN ERMİŞ, DİĞDEM; KARACA, MERT; TERZİ, ORKUN ERAY; BAYRAM, MERVE; ÖMER TOPÇU, DİLARA; Yigitliler, Busra; YURTTAŞ, AHMET; Maharramov, Shahriyar; YAZICI, GAMZE; ORAL, HALUK BARBAROS; KARADAĞ, MEHMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi.; 0000-0002-6375-1472; 0000-0001-7099-9647; 0000-0002-7400-9089; 0000-0003-3604-8826; 0000-0002-2954-4293; 0000-0001-5871-8769; 0000-0003-0463-6818; 0000-0002-9027-1132; AAG-7406-2021; AAD-1271-2019; AAH-3888-2021; K-7285-2012; AAG-8744-2021; AAI-3169-2021; JPK-7012-2023; AAE-9142-2019Background/aim: COVID-19 patients have a wide spectrum of disease severity. Several biomarkers were evaluated as predictors for progression towards severe disease. IL-21 is a member of common gamma-chain cytokine family and creates some specific effects during programming and maintenance of antiviral immunity. We aimed to assess IL-21 as a biomarker for diagnosis and outcome prediction in patients hospitalized with COVID-19. Materials and methods: Patients with a preliminary diagnosis of COVID-19 and pneumonia other than COVID-19 admitted to a tertiary care hospital were included consecutively in this comparative study. Results: The study population consisted of 51 patients with COVID-19 and 11 patients with non-COVID-19 pneumonia. Serum IL-21 concentration was markedly higher, and serum CRP concentration was significantly lower in COVID-19 patients compared to nonCOVID-19 pneumonia patients. Within COVID-19 patients, 10 patients showed radiological and clinical progression. Patients with clinical worsening had lower lymphocyte count and haemoglobin. In addition to that, deteriorating patients had higher urea, LDH levels, and elevated concentration of both IL-6 and IL-21. The cut-off value of 106 ng/L for IL-21 has 80.0% sensitivity, %60.9 specificity for discriminating patients with clinical worsening. Multivariable analysis performed to define risk factors for disease progression identified IL-6 and IL-21 as independent predictors. Odds ratio for serum IL-6 concentrations >_ 3.2 pg/mL was 8.07 (95% CI: 1.3747.50, p = 0.04) and odds ratio for serum IL-21 concentrations >_ 106 ng/L was 6.24 (95% CI: 1.04 - 37.3, p = 0.02). Conclusion: We identified specific differences in serum IL-21 between COVID-19 and non-COVID-19 pneumonia patients. Serum IL-21 measurement has promising predictive value for disease progression in COVID-19 patients. High serum IL-6 and IL-21 levels obtained upon admission are independent risk factors for clinical worsening.Publication Is serum iron responsive protein-2 level associated with pulmonary functions and frequent exacerbator phenotype in copd?(Turkish Assoc Tuberculosis & Thorax, 2020-01-01) Öztürk, Nilufer Aylin Acet; ACET ÖZTÜRK, NİLÜFER AYLİN; Dilektaşlı, Aslı Görek; GÖREK DİLEKTAŞLI, ASLI; Demirdoğen, Ezgi; DEMİRDÖĞEN, EZGİ; Coşkun, Funda; COŞKUN, NECMİYE FUNDA; Ursavas, Ahmet; URSAVAŞ, AHMET; Karadağ, Mehmet; KARADAĞ, MEHMET; Uzaslan, Esra Kunt; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Göğüs Hastalıkları Anabilim Dalı.; 0000-0002-6375-1472; 0000-0001-7099-9647; 0000-0002-7400-9089; 0000-0003-3604-8826; 0000-0002-9027-1132; JPK-7012-2023; Z-1424-2019; AAI-3169-2021; AAD-1271-2019; AAH-9812-2021; AAI-1004-2021; AAG-8744-2021Introduction: Chronic Obstructive Pulmonary Disease (COPD) exacerbations contribute to the overall severity in individual patients because they are associated with airway inflammation, pulmonary function loss, decreased quality of life and increased mortality. Although, identifying frequent exacerbator patients is important due to severe outcomes associated with frequent exacerbator phenotype in COPD patients there is no single biomarker which can differentiate this phenotype. Iron responding protein-2 (IRP2) is the protein product of IREB2 gene, which is a COPD susceptibility gene that regulates cellular iron homeostasis and has a key role in hypoxic conditions. Previous research indicates that IREB2 expression in lung tissue is associated with spirometric measurements and emphysema in COPD. In this study, our aim was to investigate whether serum IRP2 levels were associated with frequent exacerbator phenotype, to evaluate whether IRP2 levels in serum are associated with pulmonary functions and selected systemic inflammation biomarkers.Materials and Methods: Designed as a single tertiary care center based, cross-sectional study, included high risk (GOLD C, D) COPD patients who admitted to outpatient clinic consecutively between December 2015 and July 2016.Results: The study included 80 COPD patients. Serum IRP2 levels were negatively correlated with FEV ml (r= -0.25, p= 0.02) and body weight (r= -0.35, p= 0.002) but not with markers of systemic inflammation. COPD patients with at least one exacerbation history in the last year tended to have higher 1RP2 levels than patients without any exacerbation (12.3 (IQR 25-75: 10.417.1) vs 10.5 (1QR 25-75: 8.8-18.5), p= 0.061.Conclusion: Serum IRP2 level is significantly correlated with FEV1 mL but not with FEV1 predicted and cannot be used to differentiate frequent exacer bator patients. Although IREB2 gene expressions in lung tissue and bronchoalveolar lavage results have significant associations with emphysema and FEV1/FVC, FEV1 %predicted in COPD patients, our results suggests serum IRP2 level is not as promising.Publication Nutritional parameters and dyspnea status in end-stage renal disease patients(European Respiratory Soc Journals Ltd, 2020-09-07) Güçlü, Özge Aydın; Deveci, Filiz; Erol, Haşim Atakan; Dilektaşlı, Aslı Gürek; GÖREK DİLEKTAŞLI, ASLI; Coskun, Funda; COŞKUN, NECMİYE FUNDA; Karadag, Mehmet; KARADAĞ, MEHMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi; 0000-0003-3604-8826; AAD-1271-2019Publication Relationship with excessive daytime sleepiness and serum substance P levels in OSAS patients and the effect of PAP treatment(Springer Japan, 2019-07-01) Güçlu, Özge Aydın; Ursavaş, Ahmet; Kasapoğlu, Fikret; Özarda, Yeşim; Bozyiğit, Cengiz; Ocakoğlu, Gökhan; Karadağ, Mehmet; AYDIN GÜÇLÜ, ÖZGE; URSAVAŞ, AHMET; KASAPOĞLU, FİKRET; ÖZARDA, YEŞİM; BOZYİĞİT, CENGİZ; OCAKOĞLU, GÖKHAN; KARADAĞ, MEHMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Göğüs Hastalıkları Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Kulak Burun Boğaz Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Biyokimya Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı.; 0000-0003-1005-3205; 0000-0003-2215-6973; 0000-0002-1114-6051; 0000-0002-9027-1132; AAI-3877-2021; AAI-3169-2021; AAH-5180-2021; AAL-8873-2021; HLG-6346-2023; AAG-8744-2021; AAG-9930-2019; AAE-1623-2022Obstructive sleep apnea syndrome (OSAS) is a commonly seen disorder characterized by repeated episodes of upper airway obstruction during sleep leading to intermittent hypoxemia or arousal. We aim to evaluate the effects of positive airway pressure (PAP) treatment on daytime sleepiness and serum Substance P (SP) levels in OSAS patients. Seventy-one consecutive patients with newly diagnosed OSAS and 19 non-apneic control subjects were enrolled to the study. PAP treatment indicated subjects were re-evaluated after 3 months of treatment. Morning SP levels of OSAS patients and Epworth sleepiness scale (ESS) were assessed at the beginning and then after 3 months of PAP treatment. Of the patients 71 (78.9%) were male and 19 (21.1%) were female, with a median age of 45 [20-62]. The levels of SP in the OSAS group were significantly lower than the snorer group and a significant correlation was not found between serum levels of SP and ESS. SP levels were negatively correlated with AHI. The baseline SP median was 336.1pg/mL [121.6-536.1], while the 3rd month SP median was 213.1pg/mL [103.5-727.6]. Serum SP values were found to have significantly decreased at 3months (p<0.0001). Statistically significant correlation was not found between percentage of ESS change and the percentage of SP change. It can be assumed that the SP level is reduced as part of the compensation mechanism in OSAS cases and supporting this mechanism, the PAP therapy further reduces the SP value by relieving the cases from apnea and the intermittent hypoxia burden.Publication Respiratory morbidity and exacerbations in patients with copd diagnosed with the fixed ratio and the lower limit of normal(European Respiratory Soc Journals Ltd, 2023-09-09) Dilektaşlı, Aslı Görek; GÖREK DİLEKTAŞLI, ASLI; COŞKUN, NECMİYE FUNDA; Yiğitliler, Büşra; Öztürk, Nilufer; ACET ÖZTÜRK, NİLÜFER AYLİN; UZASLAN, AYŞE ESRA; Uzaslan, Esra; Karadağ, Mehmet; KARADAĞ, MEHMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi.; 0000-0001-7099-9647; 0000-0002-9027-1132; AAG-8744-2021Publication Sarcoidosis and sjogren's syndrome: Mimicry or coexistence?(Elsevier, 2015-10-01) Dilektaşlı, Aslı Görek; Çetinoğlu, Ezgi D.; Durmuş, Eda; Uzaslan, Esra; Karadağ, Mehmet; GÖREK DİLEKTAŞLI, ASLI; Çetinoğlu, Ezgi D.; Durmuş, Eda; UZASLAN, AYŞE ESRA; KARADAĞ, MEHMET; Uludağ Üniversitesi/Tıp Fakültesi/Göğüs Hastalıkları Anabilim Dalı; 0000-0001-7099-9647; 0000-0002-7400-9089; 0000-0002-9027-1132; AAG-8744-2021; JPK-7012-2023; DTT-7416-2022; AAH-9812-2021; ETU-0442-2022; CDI-1977-2022
