Publication Evaluation of the cases with non-cystic fibrosis bronchiectasis(Galenos Yayıncılık, 2018-01-01) Korkmaz, Serpil; Canıtez, Yakup; Çekiç, Şükrü; Efe, Hülya Poyraz; Ocakoğlu, Gökhan; Sapan, Nihat; Korkmaz, Serpil; CANITEZ, YAKUP; ÇEKİÇ, ŞÜKRÜ; Efe, Hülya Poyraz; OCAKOĞLU, GÖKHAN; SAPAN, NİHAT; Uludağ Üniversitesi/Tıp Fakültesi/Çocuk Alerji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı.; 0000-0002-9574-1842; 0000-0002-1114-6051; HLG-6346-2023; L-1933-2017; CJQ-2060-2022; CPN-6371-2022; FFE-8839-2022; FUI-8766-2022INTRODUCTION: Bronchiectasis is a chronic inflammatory disease characterized by a permanent dilation of the bronchial wall. We aimed to evaluate pediatric cases diagnosed with non-cystic fibrosis bronchiectasis.METHODS: A total of 98 cases who were diagnosed with non-cystic fibrosis bronchiectasis and were being followed-up between January 2010 and January 2015 at our clinic were included. Clinical, laboratory and radiological evaluations were recorded from patients electronic files.RESULTS: Female to male ratio of the cases was 1.3 (56/42). The median age of the cases was 12.2 years (1-18), the median age of diagnosis was 6 years (1-17 years), and the median duration of follow-up was 38 months (3-140 months).The most common symptom of the cases was cough (n: 91, 93%) followed by sputum expectoration (n: 56, 57%). In the pulmonary function tests performed during the initial phase of diagnosis; restrictive pattern was seen in 29.1% (n = 21) of patients and obstructive pattern was seen in 23.2% (n = 17). Furthermore, in last control visit, restrictive pattern was seen in 17.3% (n=9) of them and obstructive pattern was seen in 44.2% (n = 23). The most frequent etiological cause was infectious diseases (n: 41, 42%). Bronchiectasis was seen most commonly in the left lower lobe of the lung (n: 52, 53%), followed by the right lower lobe (n=32, 33.7%).DISCUSSION and CONCLUSION: Bronchiectasis is still a major health problem in developing countries and causes irreversible damage to the lung when untreated. Postinfectious lung diseases are one of the most important causes of bronchiectasis in children. Early diagnosis improves treatment success.Publication Prognostic value of estrogen receptors in patients who underwent prostatectomy for non-metastatic prostate cancer(Spandidos Publ Ltd, 2023-02-01) Aydın, Yavuz Mert; Şahin, Ahmet Bilgehan; Dölek, Rabia; Vuruşkan, Berna Aytaç; Ocakoğlu, Gökhan; Vuruşkan, Hakan; Yavaşçaoğlu, İsmet; Coşkun, Burhan; AYDIN, YAVUZ MERT; ŞAHİN, AHMET BİLGEHAN; DÖLEK, RABİA; AYTAÇ VURUŞKAN, BERNA; OCAKOĞLU, GÖKHAN; VURUŞKAN, HAKAN; YAVAŞCAOĞLU, İSMET; COŞKUN, BURHAN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Üroloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Onkoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Patoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı.; 0000-0002-6287-6767; 0000-0002-7846-0870; 0000-0002-1114-6051; 0000-0002-8242-9921; AAH-9704-2021; AFP-3055-2022; HSH-9815-2023; JCO-5169-2023; AAH-5180-2021; AAM-4927-2020; EEJ-1452-2022; EFH-9523-2022; EIN-0828-2022Estrogen receptors in prostate cancer (PCa) are a subject of debate. The aim of the present study was to investigate whether estrogen receptor-alpha (ER alpha) and estrogen receptor-beta (ER beta) impact the biochemical recurrence (BCR) of non-metastatic PCa after surgery. Following the application of the exclusion criteria, data from 108 patients who underwent laparoscopic radical prostatectomy between January 2011 and December 2019 were retrospectively evaluated. A total of 36 patients with BCR constituted the BCR group. The control group was formed using the Propensity Score Matching (PSM) method with a 1:2 ratio, including parameters with well-studied effects on BCR. The median follow-up time was 74.3 (range, 30-127.5) months in the BCR group and 66.6 (range, 31.5-130) months in the control group. Pathology specimens from the two groups were immunohistochemically stained with ER alpha and ER beta antibodies. Logistic regression analysis and survival analysis were performed. No differences in clinicopathological characteristics were detected between the two groups. The patients with ER alpha(-)/ER beta(+) staining results had a significantly fewer BCRs than other patients (P=0.024). In the logistic regression analysis, patients with ER alpha(-)/ER beta(+) PCa also had a significantly lower risk of recurrence (P=0.048). In the survival analysis, the 5-year BCR-free survival rate of patients with ER alpha(-)/ER beta(+) PCa was higher than that of other patients (85.7 vs. 66.1%; P=0.031). Excluding the effects of well-studied risk factors for recurrence by the PSM method, the present study showed that ER alpha and ER beta have prognostic value for non-metastatic PCa. The 5-year BCR-free survival rate is significantly higher in patients whose PCa tissue has ER alpha(-)/ER beta(+) staining results.Publication Pregnancy and kidney transplantation: A single-center experience(Aves, 2022-07-01) Ayar, Yavuz; Sayılar, Emel Işıktaş; Demir, Bilge Cetinkaya; ÇETİNKAYA DEMİR, BİLGE; ERSOY, ALPARSLAN; OCAKOĞLU, GÖKHAN; YILDIZ, ABDULMECİT; ORUÇ, AYŞEGÜL; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Nefroloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Jinekoloji ve Doğum Anabilim Dalı.; 0000-0003-4607-9220; 0000-0002-1114-6051; 0000-0002-0342-9692; 0000-0001-6845-9991; AAH-5180-2021; AAH-4002-2021Objective: The possibility of pregnancy increases with kidney transplantation in patients with chronic kidney disease. However, graft dysfunction, risk of fetal growth retardation, and fetal anomaly should be monitored closely. In this study, renal and obstetric outcomes were analyzed in pregnant kidney recipients who were followed in our center.Methods: We analyzed 140 reproductive-aged patients who underwent renal transplantation between January 2009 and May 2015, and clinical and laboratory data were evaluated retrospectively.Results: Twenty-four patients became pregnant (17.1%). In pregnant group, median age was significantly lower than nonpregnant group (P =.014). The median age of pregnant group at the time of transplantation was also significantly lower than non-pregnant patients (P <.001). The rate of pregnant patients was 66.7% in 18-25 year age group (P =.008). The rate of urinary tract infection in non-pregnant group was higher than pregnant group (P =.03). Live birth rates were 83.3% and 45.8% of those whose birth weight was higher than 2500 g. The increased level of daily urinary proteinuria and the time from diagnosis of renal failure to transplantation had significant effect on pregnancy (odds ratio = 13.81;95% CI: 2.06-92.45; P =.007 and odds ratio = 3.25;95% CI: 1.11-9.48; P =.031, respectively). Low serum creatinine level had significant protective effect (odds ratio = 0.001; 95% CI: 0-0.30, P =.018). The patients in 18-25 age group were 48.39 times more eligible for pregnancy compared to those in >35 age group (odds ratio = 48.39; 95% CI: 1.26-1860.72; P =.037). Rejection episodes were observed in 1 of pregnant women and 11 of non-pregnant women (P >.05).Conclusion: Pregnancy is possible in kidney transplant recipients of reproductive age. Calcineurin inhibitors and azathioprine seem to be safe. Maternal age, low-serum creatinine, and urinary proteinuria affect pregnancy. The close monitoring of renal function and fetal parameters is very important.Publication Is there a relationship between the diameter of the inferior vena cava and hemodynamic parameters in critically ill patients?(Medknow Publications, 2015-11-01) Aydın, Şule A.; Özdemir, Fatma; Taşkın, G.; Ocakoğlu, Gökhan; Yıldırım, H.; Köksal, Özlem; AYDIN, ŞULE; ÖZDEMİR, FATMA; Taşkın, G.; OCAKOĞLU, GÖKHAN; KÖKSAL, ÖZLEM; Uludağ Üniversitesi/Tıp Fakültesi/Acil Servis Bölümü; Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı; 0000-0002-1114-6051; AAH-5180-2021; AAK-8332-2020; HLG-6346-2023; AAI-2164-2021; IOY-2055-2023; GHW-4797-2022Introduction: The early detection of critically ill patients together with the rapid initiation of effective treatment in emergency departments(ED) increase the survival rates.Aim: This study investigated whether a correlation exists between haemodynamic parameters of critically ill patients and the diameter of the inferior vena cava (IVC).Materials and Methods: A cross-sectional study was performed included patients aged >= 18 years with an unstable haemodynamic and/or respiratory status who were referred to the ED for non-traumatic issues. IVC diameters were measured by ultrasound (US) and then central venous pressures (CVP) were measured. Anteroposterior (AP) and mediolateral (ML) diameters of the IVC, both in the inspirium (IAP, IML) and expirium (EAP, EML), were measured by US.Results: 102 patients were evaluated with a median age of 59. The relationship between the diameters of IVC and CVP was evaluated and significant correlation was found in IAP, EAP according to CVP values (p<0.001). ROC analyses were performed and significant relationship was found between the EAP diameter with haemoglobin (Hmg), haemotocrit (Hct), and central venous oxygen saturation (ScvO2) and also significant correlation was detected between the IAP diameter and white blood cell (WBC).Discussion: We detected significant correlation between the CVP and the IVC diameter in our study compatible with recent studies besides, significant correlation was found between the diameter of the IVC and CVP values as well as between the EAP diameter and Hmg, Hct, ScvO2 levels.Conclusion: Measurement of IVC diameters, especially EAP may be useful at the monitoring of critically ill patients in ED.Publication Retrospective analysis of decompressive craniectomy performed in pediatric patients with subdural hematoma(Travma Acil Cerrahisi, 2019-07-01) Taşkapılıoğlu, M.

In this paper, we aimed to investigate the role of decompressive craniectomy performed to treat traumatic subdural hematoma in patients from the pediatric age group.METHODS: We described our experience with DC in pediatric acute subdural hematoma patients and analyzed the outcomes.RESULTS: Eleven (7 unilateral and 4 bilateral) DCs were performed. The patients' ages ranged from 8 months to 15 years. The mean GCS score at admission was 7.8. All patients underwent DC with duraplasty within 2 hours of injury. All the patients were admitted to the intensive care unit for 10 days postoperatively. The mean hospital stay was 22 days and the mean follow-up period was 3.7 years.CONCLUSION: Early DC for pediatric subdural hematoma patients, independent of their initial GCS, was recommended. Larger studies are needed to define the indications, surgical techniques, and timing of DC in the pediatric population.Publication Development and validation of a simple risk scoring system for a COVİD-19 diagnostic prediction model(Tüberküloz ve Toraks, 2023-01-01) Güçlü, Özge Aydın; Ursavaş, Ahmet; Ocakoğlu, Gokhan; Demirdogen, Ezgi; Öztürk, Nilufer Aylin Acet; Topçu, Dilara Ömer; Terzi, Orkun Eray; Onal, Uğur; Dilektaşlı, Aslı Görek; Sağlık, İmran; Coşkun, Funda; Ediger, Dane; Uzaslan, Esra; AkalIn, Halis; Karadağ, Mehmet; AYDIN GÜÇLÜ, ÖZGE; URSAVAŞ, AHMET; OCAKOĞLU, GÖKHAN; DEMİRDÖĞEN, EZGİ; ACET ÖZTÜRK, NİLÜFER AYLİN; ÖMER TOPÇU, DİLARA; TERZİ, ORKUN ERAY; ÖNAL, UĞUR; GÖREK DİLEKTAŞLI, ASLI; SAĞLIK, İMRAN; COŞKUN, NECMİYE FUNDA; EDİGER, DANE; UZASLAN, AYŞE ESRA; AkalIn, Halis; KARADAĞ, MEHMET; Uludağ Üniversitesi/Tıp Fakültesi/Göğüs Hastalıkları Anabilim Dalı; Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı; Uludağ Üniversitesi/Tıp Fakültesi/Enfeksiyon Hastalıkları ve Klinik Mikrobiyoloji Anabilim Dalı; 0000-0003-1005-3205; 0000-0002-1114-6051; 0000-0002-7400-9089; 0000-0002-6375-1472; 0000-0001-7099-9647; 0000-0002-2954-4293; 0000-0001-7530-1279; 0000-0002-9027-1132; AAH-5180-2021; A-4970-2019; AAG-8744-2021; AAI-3169-2021; JCO-3678-2023; JPK-7012-2023Introduction: In a resource-constrained situation, a clinical risk stratification system can assist in identifying individuals who are at higher risk and should be tested for COVID-19. This study aims to find a predictive scoring model to estimate the COVID-19 diagnosis.Materials and Methods: Patients who applied to the emergency pandemic clinic between April 2020 and March 2021 were enrolled in this retrospective study. At admission, demographic characteristics, symptoms, comorbid diseases, chest computed tomography (CT), and laboratory findings were all recorded. Development and validation datasets were created. The scoring system was performed using the coefficients of the odds ratios obtained from the multivariable logistic regression analysis.Results: Among 1187 patients admitted to the hospital, the median age was 58 years old (22-96), and 52.7% were male. In a multivariable analysis, typical radiological findings (OR= 8.47, CI= 5.48-13.10, p< 0.001) and dyspnea (OR= 2.85, CI= 1.71-4.74, p< 0.001) were found to be the two important risk factors for COVID-19 diagnosis, followed by myalgia (OR= 1.80, CI= 1.082.99, p= 0.023), cough (OR= 1.65, CI= 1.16-2.26, p= 0.006) and fatigue symptoms (OR= 1.57, CI= 1.06-2.30, p= 0.023). In our scoring system, dyspnea was scored as 2 points, cough as 1 point, fatigue as 1 point, myalgia as 1 point, and typical radiological findings were scored as 5 points. This scoring system had a sensitivity of 71% and a specificity of 76.3% for a cut-off value of >2, with a total score of 10 (p< 0.001).Conclusion: The predictive scoring system could accurately predict the diagnosis of COVID-19 infection, which gave clinicians a theoretical basis for devising immediate treatment options. An evaluation of the predictivePublication Can diffusion weighted magnetic resonance imaging differentiate between inflammatory-infectious and malignant pleural effusions?(Assoc Royal Soc Scientifiques Medicales Belges, 2015-03-01) Karatag, O.; Alar, T.; Koşar, S.; Ocakoğlu, Gökhan; Yıldız, Y.; Gedik, E.; Gönlügür, U.; Özdemir, H.; OCAKOĞLU, GÖKHAN; Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Bölümü; AAH-5180-2021; HLG-6346-2023Aim: To assess exudative pleural effusions with diffusion-weighted magnetic resonance imaging (DW-MRI) in order to determine non-invasive differentiation criteria for inflammatory-infectious and malignant effusions.Materials and methods: Thirty-two patients with pleural effusions underwent DW-MRI with 4 different b values (10, 500, 750 and 1000 s/mm(2)). ADC maps were generated automatically. Signal intensity and ADC values were measured. Following MRI, pleural fluid of 10-15 ml was obtained and analyzed. AUC values were compared for different diffusion levels of ADC and SI measurements. The relationship between ADC values and pleural effusion LDH and total protein levels was examined.Results: The cut-off values obtained from signal intensity and ADC measurements to differentiate exudates with malignant pathology were not found to be statistically significant. In the inflammatory-infectious group, a significant negative correlation was observed between ADC values and pleural fluid LDH measurements in all b values. In the malignant group, a significant positive correlation was observed between ADC values and pleural fluid total protein measurements in b values of 500 and 1000.Conclusion:Infectious/inflammatory and malignant effusions overlap strongly and cannot therefore be differentiated using DW MRI.Publication Bilateral 4-quadrant laparoscopic-assisted transversus abdominis plane block reduces early postoperative pain after laparoscopic cholecystectomy a prospective, single-blind, randomized study(Saudi Med J, 2023-02-01) Çevikkalp, Eralp; Narmanlı, Mustafa; Özgüç, Halil; Ocakoğlu, Gökhan; OCAKOĞLU, GÖKHAN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı.; 0000-0002-1114-6051Objectives: To investigate the efficacy of bilateral 4-quadrant laparoscopic-assisted transversus abdominis plane (BLTAP) block in laparoscopic cholecystectomy (LC).Methods: This study was carried out at Private Medicabil Hospital, Bursa, Turkey, between September 2021 and March 2022. Patients were randomly divided into 4 groups (n=40, each): i) the standard analgesia (SA) group received the block and port-site infiltration with normal saline (NS); ii) the local anesthetic group received the block with NS and port-site infiltration of bupivacaine; iii) the unilateral laparoscopic-assisted transversus abdominis plane (ULTAP) block group received 2-quadrant block with bupivacaine on the right and NS on the left and port-site NS infiltration; and iv) the BLTAP block group received bilateral bupivacaine and port-site NS infiltration. Postoperative 1-, 3-, 6-, 12-, and 24-hours visual analog scale (VAS) pain scores at rest and during cough, opioid requirement, presence of nausea and vomiting, and satisfaction scores were recorded.Results: The one-hour VAS score at rest was lower in the BLTAP block group than in the SA and ULTAP block groups. The change in VAS score was higher in the SA group than in the BLTAP block group. During cough, the one-hour VAS score was lower in the BLTAP block group than in the SA group. There were no differences among groups in other parameters. Conclusion: Bilateral 4-quadrant laparoscopic-assisted transversus abdominis plane block technique is more effective than SA, local anesthetic infiltration, and ULTAP block in preventing early postoperative pain after LC.Publication Association of morning blood pressure surge (mbps) with left ventricular hypertrophy in autosomal dominant polycystic kidney disease (ADPKD): Across sectional study(Oxford Univ Press, 2016-05-01) Sağ, Saim; Yıldız, Abdulmecit; Ersoy, Alparslan; Ocakoğlu, Gökhan; Oruç, Ayşegül; Güngören, Fatih; Ayar, Yavuz; Gül, Cuma Bülent; Güllülü, Sümeyye; Güllülü, Mustafa; Sağ, Saim; YILDIZ, ABDULMECİT; ERSOY, ALPARSLAN; OCAKOĞLU, GÖKHAN; ORUÇ, AYŞEGÜL; Güngören, Fatih; Ayar, Yavuz; GÜL, CUMA BÜLENT; GÜLLÜLÜ, NAZMİYE SÜMEYYE; GÜLLÜLÜ, MUSTAFA; Uludağ Üniversitesi/Tıp Fakültesi/Kardioloji Bölümü; 0000-0002-1114-6051; 0000-0002-0342-9692; 0000-0003-4607-9220; 0000-0003-2467-9356; AAH-5180-2021; AGF-0767-2022; AAW-9185-2020; AAH-5054-2021; O-9948-2015; AAA-3163-2021; HLG-6346-2023; AAH-4002-2021; A-7063-2018; GSE-0029-2022; HIG-9032-2022; JGR-6552-2023; CTG-8811-2022Publication 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.
