Aortic diameters, aortic distensibility, microalbuminuria, coronary artery disease which are all together related to vascular aging are investigated in this paper. Methods. Eighty consecutive nondiabetic patients undergoing elective coronary angiography were enrolled into the study. Systolic and diastolic aortic diameters, aortic distensibility, CAD severity by angiogram with the use of Gensini scoring, and albumin excretion rates were determined. Results. Cases with CAD had significantly larger systolic (30,72 +/- 3,21mm versus 34,19 +/- 4,03 mm for cases without and with CAD, resp.) and diastolic aortic diameters measured 3 cm above aortic valve compared to patients without CAD (33,56 +/- 4,07 mm versus 29,75 +/- 3,12 mm). The systolic and diastolic diameters were significantly higher in albuminuria positive patients compared to albuminuria negative patients (p = 0.017 and 0.008, resp., for systolic and diastolic diameters). Conclusion. In conclusion aortic diameters are increased in patients with coronary artery disease and in patients with microalbuminuria. In CAD patients, systolic blood pressure, pulse pressure, aortic systolic and diastolic pressure, and albumin excretion rate were higher and aortic distensibility was lower.Publication Dislodgement of a sirolimus-eluting stent in the circumflex artery and its successful deployment with a small-balloon technique(Turkish Soc Cardiology, 2011-07-01) Şentürk, Tunay; YEŞİLBURSA, DİLEK; ŞENTÜRK, TUNAY; ÖZDEMİR, BÜLENT; Özdemir, Bülent; Serdar, Osman Akın; SERDAR, OSMAN AKIN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Kardiyoloji Anabilim Dalı.; 0000-0003-1744-8883; AAF-5116-2019; C-1517-2017Coronary stent dislodgement or embolization before deployment is a rare but serious complication in interventional cardiology. A 60-year-old male presented with unstable angina five years after coronary artery bypass surgery. There was a stenosis (70%) in the obtuse marginal branch of the circumflex artery. During percutaneous coronary intervention, a sirolimus-eluting stent was stripped from its balloon mainly because of significant proximal angulation and incarcerated within the proximal circumflex artery. A smaller balloon dilatation catheter was advanced and pushed through the inside of the slipped stent. Using this technique, the stent could be advanced into the lesion and was successfully deployed. To our knowledge, this is the first case report on sirolimus-eluting stent dislodgement.Publication Serum fetuin-a levels for the detection and evaluation of the left ventricular systolic heart failure(Elsevier, 2013-10-29) Keçebaş, Mesut; Güllülü, Sümeyye; Sağ, Saim; Açıkgöz, Ebru; Besli, Feyzullah; Şentürk, Tunay; Kaderli, Aysel Aydın; Özdemir, Bülent; Baran, İbrahim; Sarandöl, Emre; Aydınlar, Ali; Keçebaş, Mesut; GÜLLÜLÜ, NAZMİYE SÜMEYYE; Sağ, Saim; Açıkgöz, Ebru; Besli, Feyzullah; ŞENTÜRK, TUNAY; Kaderli, Aysel Aydın; ÖZDEMİR, BÜLENT; Baran, İbrahim; SARANDÖL, EMRE; AYDINLAR, ALİ; Uludağ Üniversitesi/Tıp Fakültesi/Kardiyoloji Anabilim Dalı; Uludağ Üniversitesi/Tıp Fakültesi/Biyokimya Anabilim Dalı; 0000-0002-6206-8700; C-1517-2017; ABE-1716-2020; AAW-9185-2020; AAI-6632-2021; JKQ-3658-2023; JGR-6552-2023; CBS-6076-2022; DXE-4816-2022; CXL-7581-2022; JHE-3353-2023; CDA-1396-2022Publication A family with IgA nephropathy and hereditary lymphoedema praecox(Wiley, 2002-05-01) Usta, M; Dilek, Kamil; Ersoy, Ahmet; Alper, E; Özbek, Serhat; Özdemir, Bülent; Filiz, G; Yavuz, M; Güllülü, Mustafa; Yurtkuran, Merih; Usta, M; DİLEK, KAMİL; Ersoy, Ahmet; Alper, E; ÖZBEK, SERHAT; ÖZDEMİR, BÜLENT; Filiz, G; Yavuz, M; GÜLLÜLÜ, MUSTAFA; Yurtkuran, Merih; Uludağ Üniversitesi Tıp Fakültesi/Nefroloji Bölümü; Uludağ Üniversitesi Tıp Fakültesi/Nükleer Tıp Bölümü; Uludağ Üniversitesi Tıp Fakültesi/Plastik ve Rekonstrüktif Cerrahi; Uludağ Üniversitesi Tıp Fakültesi/Patoloji Anabilim Dallarından; 0000-0003-3427-8337; 0009-0001-9179-9107; HYD-3798-2023; CNY-9323-2022; GXG-1656-2022; CCY-8570-2022; FTG-3544-2022; JHE-3353-2023; EVQ-8652-2022; HJG-9929-2022; JGS-9425-2023; GLB-5791-2022Immunoglobulin A (IgA) nephropathy is the most common primary glomerulonephritis worldwide. The pathogenesis is still unknown and treatment has not yet been established. Rarely it can be associated with other disorders. Its association with hereditary lymphoedema is not reported before. We report four patients, a 60-year-old father, his two sons and his daughter, with hereditary lymphoedema. The family had nine members and in four of them lymphoedema was evident. The other members had neither lymphoedema nor IgA nephropathy. This is the first report of IgA nephropathy in association with hereditary lymphoedema.Publication A comparison of percutaneous and mini-open techniques of Achilles tenotomy: An experimental study in rats(British Editorial Soc Bone Joint Surgery, 2009-12-01) Doğan, Ahmet; Uzumcugil, Onat; Sarısözen, Bartu; Özdemir, Bülent; Akman, Y. Emre; Bozdağ, Ergün; Sunbuloğlu, Emin; Bozkurt, Erol; SARISÖZEN, MEHMET BARTU; ÖZDEMİR, BÜLENT; Uludağ Üniversitesi/Tıp Fakültesi/Ortopedi ve Travmatoloji Kliniği; 0000-0003-4071-8052; FVC-9695-2022; ABI-7283-2020Purpose To investigate the effect of Achilles tenotomy performed percutaneously and by mini-open methods on tendon healing and final strength.Materials and methods In two groups, each consisting of 14 rats, percutaneous and mini-open techniques in Achilles tenotomy were compared in terms of biomechanical, histological and gross properties.Results In the gross evaluation, it was observed that an obvious thickening and adhesion to the subcutaneous tissue of the healing tendon were observed in nearly all rats in which the mini-open technique was performed. In the biomechanical analysis, there was no significant difference between percutaneous and mini-open groups and between operated and intact Achilles tendons in both groups, in terms of tendon strength (P > 0.05). In the histological evaluation, irregularity in the parallel pattern of the collagen fibres, emergence of a non-specific collagenous tissue formation and infiltration of mild mononuclear inflammatory cells were reported. These changes were more marked in the rats in which the percutaneous technique was performed.Conclusion Mini-open technique for Achilles tenotomy may be considered as an alternative method of treatment to apply the tenotomy technique in a secure way. Clinical relevance There are two basic advantages of Achilles tenotomy performed by the mini-incision open technique: (1) a complete tenotomy is guaranteed, as it has to be in the original Ponseti technique, (2) iatrogenic neuro-vascular injury risk is nearly completely avoided due to the subparatenon exploration of the tendon and direct visual observation during the transection. The mini-open technique may only be used in cases in which a vascular compromise is clinically suspected or confirmed by Doppler ultrasonography and/or arteriography. On the other hand, the technique may be performed in all cases routinely by the choice of the surgeon.Publication Attitudes of smoking and knowledge about substances in cigarette smoke in university students(Scibulcom, 2015-01-01) Özdemir, A.; Utkualp, N.; Özdemir, B.; Özdemir, L.; ÖZDEMİR, AYSEL; UTKUALP, NEVİN; ÖZDEMİR, BÜLENT; ÖZDEMİR, LEVENT; Uludağ Üniversitesi/Sağlık Bilimleri Fakültesi/Halk Sağlığı Hemşireliği Bölümü.; Uludağ Üniversitesi/Tıp Fakültesi/Kardiyoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Halk Sağlığı Anabilim Dalı.; 0000-0002-0815-9505; 0000-0002-4330-8334; AAJ-1202-2021; C-7487-2018; AAC-9352-2021; FRF-3343-2022Smoking is a worldwide problem causing significant mortality. Due to the complications occurring later in life giving up is not intended for many users. Media, environment, family, friends, and cultural factors are effective in the onset and prolongation of this habit.In this study we aimed to determine the knowledge level of 188 students of the Institute of Health Sciences who gave informed consent and participated in the study. We gathered data with a questionnaire form and asked questions related to the diseases proven to be caused by smoking and the substances in the cigarette smoke. We used the Fagerstrom Nicotine Dependence Test to evaluate the nicotine dependence status of smoking students. The mean age of the students was 20.49 +/- 1.19 and the number of females was 144 (76.6%). The mean age of onset of smoking and alcohol consumption was 17.04 +/- 2.13 and 17.06 +/- 2.34, respectively. Overall rate of smoking was 11.7% (n = 22) and in females and males 7.6 and 25.0%, respectively (p < 0.003).It was concluded that the smoking rate in students of the Institute of Health Sciences is high, particularly in male students. The knowledge of substances in cigarette smoke did not affect the smoking pattern of students.Publication Association of epicardial adipose tissue thickness by echocardiography and heart rate recovery in metabolic syndrome(Elsevier, 2013-10-29) Böyük, Ferit; Özdemir, Bülent; Sağ, Saim; Şentürk, Tunay; Kaderli, Aysel Aydın; Güllülü, Sümeyye; Aydınlar, Ali; Böyük, Ferit; ÖZDEMİR, BÜLENT; Sağ, Saim; ŞENTÜRK, TUNAY; Kaderli, Aysel Aydın; GÜLLÜLÜ, NAZMİYE SÜMEYYE; AYDINLAR, ALİ; Uludağ Üniversitesi/Tıp Fakültesi/Kardiyoloji Bölümü; C-1517-2017; AAI-6632-2021; AAW-9185-2020; JIX-2728-2023; JHE-3353-2023; CXL-7581-2022; JGR-6552-2023Publication The relationship between Cardiotrophin-1 and Troponin-I in coronary arterial bypass grafting on the beating heart: A prospective study(Forum Multimedia Publishing, 2015-08-01) Çalışkan, Serhat; Beşli, Feyzullah; Yıldırım, Ahmet; Güngören, Fatih; Alışır, Mehmet Fethi; Polat, Ufuk; Özdemir, Bülent; Biçer, Murat; Çalışkan, Serhat; Yıldırım, Ahmet; Güngören, Fatih; Polat, Ufuk; ÖZDEMİR, BÜLENT; BİÇER, MURAT; Uludağ Üniversitesi/Tıp Fakültesi/Kardiyoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Kalp Damar Cerrahisi Anabilim Dalı.; 0000-0003-4411-8185; 0000-0002-0815-9505; AAA-3163-2021; ABC-2231-2020; AAC-9352-2021; ERK-8925-2022; JTI-0902-2023; DLY-6718-2022Objective: Cardiotrophin-1 (CT-1) is closely associated with many cardiovascular diseases, such as hypertension, myocardial infarction (MI), and heart failure, and exhibits a cardioprotective effect in ischemia-reperfusion injury. The aim of this study was to evaluate the relationship between CT-1 and Troponin-I (Tn-I) in off-pump coronary artery bypass (OPCAB) grafting on the beating heart.Methods: Seventy-eight patients (mean age 60.8 +/- 9.7 years, 79.5% male) undergoing elective OPCAB surgery were included in this study undertaken between July 1, 2012 and July 1, 2013 in the Department of Cardiology and Cardiac Surgery, University School of Medicine Hospital. Venous blood samples were collected 5 minutes before OPCAB surgery and 6 hours after surgery. Plasma CT-1 levels were measured using the ELISA method.Results: Compared to the preoperative period, Tn-I and CT-1 values were higher in the postoperative period [0.255 ng/mL (0.030-0.430) versus 0.045 ng/mL (0.005-0.090), P < .001; and 33.7 pg/mL (15.8-98.5) versus 8.7 pg/mL (0.68-25.4), P <. 001]. There was also an elevation in white blood cells, aspartate aminotransferase, creatine kinase (CK), and creatine kinase MB (CK-MB) values, as well as a decrease in hemoglobin values (P < .001). When a correlation analysis for postoperative CT-1 was performed, there was a significant positive correlation between postoperative CK, CK-MB, and Tn-I levels (r = 0.250, P < .027; r = 0.270, P =.017; and r = 0.241, P < .034).Conclusion: CT-1 was found to be associated with Tn-I, which is used to detect myocardial damage after OPCAB surgery. CT-1 may also be used to detect myocardial damage.Publication Association between blood pressure, inflammation and spirometry parameters in chronic obstructive pulmonary disease(Korean Assoc Internal Medicine, 2019-01-01) Arslan, Sülhattin; Yıldız, Gürsel; Özdemir, Levent; Kaysoydu, Erdal; Özdemir, Bülent; ÖZDEMİR, BÜLENT; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Kardiyoloji Anabilim Dalı.; JHE-3353-2023Background/Aims: Many systems including the cardiovascular system (ischemic heart diseases, heart failure, and hypertension) may act as comorbidities that can be seen during the course of chronic obstructive pulmonary disease (COPD). Comorbidities affect the severity and prognosis of COPD negatively. Nearly 25% of patients with COPD die due to cardiovascular diseases. In this study, we aimed to evaluate the relationship between the blood pressure, inflammation, hypoxia, hypercapnia, and the severity of airway obstruction.Methods: We included 75 COPD patients in the study with 45 control cases. We evaluated age, sex, body mass index, smoking history, C-reactive protein levels, 24-hour ambulatory blood pressure Holter monitoring, arterial blood gas, and respiratory function tests of the patient and the control groups.Results: In COPD patients, the night time systolic, diastolic blood pressures and pulse per minute and the mean blood pressures readings were significantly elevated compared to the control group (p < 0.05). In the correlation analysis, night time systolic pressure was associated with all the parameters except forced expiratory volume in 1 second (FEV1%). Diastolic blood pressure was associated with pH and HCO3 levels. The mean night time, day time pulse pressures and 24-hour pulse per minute values were also associated with all the parameters except FEV1%.Conclusions: In this study we found that parameters of systolic and diastolic blood pressures and pulse pressures were significantly elevated in COPD patients compared to the control groups. Blood pressure was associated blood gas parameters and inflammation parameters in COPD patients. This, in turn, may cause understanding of the pathophysiology of COPD and its complications.
