Item Liver Transplant and Reexpansion Pulmonary Edema: A Case Report(2018) Kara, Sibel; Sen, Nazan; Akcay, Sule; Moray, Gokhan; Kus, Murat; Haberal, Mehmet; 0000-0002-4171-7484; 0000-0002-8360-6459; 0000-0003-2498-7287; 0000-0001-6529-7579; 0000-0002-3462-7632; 29528016; AAI-8069-2021; AAI-8947-2021; AAB-5175-2021; AAE-1041-2021; AAJ-7870-2021; AAJ-8097-2021Hydrothorax occurs frequently in patients with end-stage liver disease and usually requires drainage of pulmonary effusion during the hepatectomy phase of liver transplant. Reexpansion pulmonary edema is a rare but potentially fatal complication seen after rapid reexpansion of the collapsed lung following thoracentesis of pleural fluid or tube drainage of pneumothorax. This condition, which manifests with various degrees of clinical severity, is rarely reported following liver transplantation. Herein, we present a 62-year-old male patient who developed reexpansion pulmonary edema after drainage of massive pleural effusion, which caused a total collapse in the right hemithorax during liver transplant. Six hours after pleural fluid drainage, the patient developed a nonproductive cough, mild tachypnea, shortness of breath, and low oxygen saturation (88%). His chest radiograph showed diffuse heterogeneous opacities in the right hemithorax. Computed tomography of the thorax revealed consolidations containing air bronchograms and ground glass opacities in the parenchyma of the right lung; these findings did not extend to the periphery and were observed less frequently in the inferoposterior left lung. These symptoms and radiologic findings were diagnosed as reexpansion pulmonary edema. Complete clinical and radiologic improvements were achieved within 72 hours of mechanical ventilatory support.Item Pneumonia in Renal Transplant Recipients: A Single-Center Study(2018) Kara, Sibel; Sen, Nazan; Kursun, Ebru; Yabanoglu, Hakan; Yildirim, Sedat; Akcay, Sule; Haberal, Mehmet; 0000-0002-4171-7484; 0000-0002-1161-3369; 0000-0002-5735-4315; 0000-0002-8360-6459; 0000-0002-3462-7632; 29528008; AAI-8947-2021; AAG-5020-2020; AAJ-7865-2021; AAF-4610-2019; AAI-8069-2021; AAB-5175-2021; AAJ-8097-2021Objectives: Pulmonary infections are a significant cause of morbidity and mortality in solid-organ transplant recipients despite enhanced facilities for perioperative care. The aim of this study was to evaluate the demographic characteristics, clinical course, and outcomes of renal transplant recipients with pneumonia. Materials and Methods: The medical records of all renal transplant recipients from January 2010 to December 2014 were retrospectively reviewed, and patients diagnosed with pneumonia according to Centers for Disease Control and Prevention criteria were evaluated. Pneumonia was classified as community acquired or nosocomial. Patient demographics, microbiologic findings, need for intensive care/mechanical ventilation over the course of treatment, and information about clinical follow-up and mortality were all recorded. Results: Eighteen (13.4%) of 134 renal transplant recipients had 25 pneumonia episodes within the study period. More than half (56%) of the pneumonia episodes developed within the first 6 months of transplant, whereas 44% developed after 6 months (all > 1 year). Eight cases (32%) were considered nosocomial pneumonia, and 17 (68%) were considered community-acquired pneumonia. Bacteria were the most common cause of pneumonia (28%), and fungi ranked second (8%). No viral or mycobacterial agents were detected. No patients required prolonged mechanical ventilation. No statistically significant difference was found in the need for intensive care or regarding mortality between patients with nosocomial and community-acquired pneumonia. Two patients (11%) died, and all remaining patients recovered. Conclusions: The present study confirmed that pneumonia after renal transplant is not a rare complication but a significant cause of morbidity. Long-term and close follow-up for pneumonia is necessary after renal transplant.Item Pneumococcal and Influenza Vaccines in Dialysis Patients: Vaccination Information, Rates, and Patient Awareness(2022) Kara, Sibel; Torun, Dilek; Oruc, Ebru; Habesoglu, Mehmet Ali; Akcay, Muserref Sule; GVT-0626-2022Objective: Pneumococcal and influenza vaccination rates are still far below the desired levels in dialysis patients. We aimed to determine the pneumococcal and influenza vaccination information, rates, and knowledge levels of dialysis patients. Methods: The study is a descriptive cross-sectional study in which 307 dialysis patients between 2020 and 2021 were analyzed retrospectively. Demographic characteristics of all patients and vaccination information were obtained from the face-to-face questionnaire and hospital medical records. Results: Of the participants, 52.4% were males, and the mean age was 56 +/- 15.45 years. The pneumococcal vaccination rate was 37.1%, and the influenza vaccination rate was 58.6%. Of 114 patients who had received a pneumococcal vaccine, 91.2% had received a single dose of the vaccine. While the type of vaccine could not be determined in 86.8% of the patients in this group, the rate of vaccination with the 2 types of the pneumococcal vaccine was only 8.8%. Annual vaccination was given to all those who were vaccinated against influenza. In the whole group, the rate of those who had never heard of the pneumococcal vaccine was 24.4%, while this rate was 6.5% for the influenza vaccine. The patients had a very low level of knowledge of both vaccines (41% and 53.7%, respectively). Conclusion: Pneumococcal and influenza vaccination rate of dialysis patients was low. Influenza vaccination had been performed in compliance with the recommended scheme, but the doses of the pneumococcal vaccine were incomplete. Although the level of patient knowledge was low for both vaccines, patients were more aware of the influenza vaccine.Item Factors Affecting Mortality In Geriatric Patients Diagnosed With Community-Acquired Pneumonia Treated In Intensive Care Units(2021) Bozkurt Yilmaz, Hatice Eylul; Unsal, Zuhal Ekici; Habesoglu, Mehmet Ali; Kara, Sibel; Sen, NazanIntroduction: The aim of this study was to determine the factors affecting mortality in elderly patients with community-acquired pneumonia who were receiving intensive care unit. Materials and Methods: The study was retrospective, cross-sectional, and descriptive. The medical records of patients over 65 years of age who were admitted to the intensive care unit with a diagnosis of community-acquired pneumonia between January 1, 2013 and February 29, 2020 were reviewed. The factors associated with mortality in the patients who had died were examined. Results: A total of 208 patients with a mean age of 75.11 +/- 5.59 years, 78 of whom were women (37.5%), were included in the study. During the follow-up 35 (16.82%) of 208 patients had died from pneumonia or complications due to pneumonia. According to multiple linear regression analysis, the following parameters were found to be predictors of mortality: Charlson comorbidity index value (odds ratio: 1.44, 95% confidence interval: 1.132-1.1841, p=0.003), chronic obstructive pulmonary disease (odds ratio: 0.292, 95% confidence interval: 0.094-1.149, p=0.038), congestive heart failure (odds ratio: 0.199, 95% confidence interval: 0.051-0.782, p=0.021), saturation value in arterial blood gas (odds ratio: 0.569, 95% confidence interval: 0.804-0.939, p<0.001), intubation duration (odds ratio: 3.476, 95% confidence interval: 1.880-6.425, p<0.001), hypertension (odds ratio: 3.449, 95% confidence interval: 0.941-12.649, p=0.042), and the presence of diabetes mellitus (odds ratio: 3.116, 95% confidence interval: 2.673-59.021, p=0.046). Conclusion: Community-acquired pneumonia requiring intensive care unit is a clinical condition with high mortality in the elderly patient population. The presence of comorbid diseases and prolonged intubation time may be associated with higher mortality.Item Side effects and antibody response of an inactive severe acute respiratory syndrome coronavirus 2 vaccine among health care workers(2021) Gumus, Hatice Hale; Odemis, İlker; Aliska, Hikmet Eda; Karsli, Asli; Kara, Sibel; Ozkale, Murat; Gul, Eylem; 0000-0001-9071-9606; 0000-0001-9060-3195; 0000-0003-2638-0163; 34909957; AAJ-2108-2021; AAE-2282-2021OBJECTIVE: This study aims to investigate the antibody response and the side effects of the two-dose inactive SARS-CoV-2 vaccine (CoronaVac, Sinovac, China) among a health care worker population in Turkey. METHODS: This study was a prospective, cross-sectional, single-center study conducted between December 16, 2020, and March 15, 2021. We evaluated the side effects from a questionnaire, and anti-spike immunoglobulin G response to the vaccine (0- and 28-day schedule) using an enzyme-linked immunosorbent assay. RESULTS: A total of 94 of 184 health care workers completed this study. The percentages of participants who were seronegative at baseline and achieved to the seropositivity were 21.3 and 97.9%, respectively, on day 21 after vaccinations. The seropositivity was predominantly detected in 31-45 years of the age group (55.4%, p=0.636), normal body mass index (47.8%, p=0.999), nonsmokers (64.1%, p=0.999), those without any comorbidities (73.9%, p=0.463), and those without any side effects (70.2%, p=0.256). The frequencies of overall side effects within seven days after the first and second doses of CoronaVac were 37.2 and 28.7%, respectively. The most common side effects was localized pain at the injection site (15.7 and 11.6%, respectively). CONCLUSIONS: We found that vaccination by two-dose CoronaVac could elicit a specific humoral response, and it was well tolerated in health care workers. The high seropositivity developed after the second dose attracted attention. Our study will be useful in terms of showing short-term immunity and side effects.Item Predicting Pulmonary Complications Following Upper and Lower Abdominal Surgery: ASA vs. ARISCAT Risk Index(2020) Kara, Sibel; Kupeli, Elif; Yilmaz, Hatice Eylul Bozkurt; Yabanoglu, Hakan; 0000-0002-5826-1997; 0000-0002-1161-3369; 0000-0003-0268-8999; 32259139; AAB-5345-2021; AAJ-7865-2021; AAI-8069-2021; AAK-2011-2021Objective: Postoperative pulmonary complications (POPC) account for a substantial proportion of risk related to surgery and anaesthesia. The American Society of Anesthesiologists (ASA) classification and the Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) risk index correlate Well with POPC. Here, we compared their accuracy in predicting pulmonary complications following upper and lower abdominal surgery. Methods: We retrospectively reviewed the medical records of patients undergoing upper and lower abdominal surgery. We collected patients' demographic data, comorbidities, preoperative pulmonary risk score, laboratory results, surgical data, respiratory tract infection history within one month before surges); surgical urgency, ASA scores and pulmonary complications within one month after the surgery. Results: We evaluated 241 patients [upper abdominal surgery n=121; lower abdominal surgery (UAS) n=120; mean age 55.7 +/- 3.1 years]. In the UAS. 55.13% of the patients were male. In LAS, all patients were fitmale. In both groups, the most common POPC was pleural elfin:ion with compressive atelectasis (CA). Regarding risk score, in both groups, patients with high-risk developed a higher rate of pulmonary complications [JAS (50%), LAS 140%)]. In patients with low-risk scores, the rate of pulmonary complications was significantly lower than the intermediate and high-risk groups (p<0.001). A positive correlation was observed between preoperative risk score and complications (UAS r=0.34; LAS r=0.35 LAS p<0.05). No association was observed between the ASA scores and POPC (p=0.3). Conclusion: The ASA classification was found to be a weaker modality than ARISCAT risk index to predict pulmonary complications after the upper and lower abdominal surgeries.Item Evaluation of Subclinical Atherosclerosis with Carotid Intima-Media and Epicardial Fat Thickness in Patients with Sarcoidosis(2020) Yilmaz, Hatice Eylul Bozkurt; Yilmaz, Mustafa; Erol, Tansel; Sen, Nazan; Unsal, Zuhal Ekici; Kara, Sibel; Habesoglu, Mehmet Ali; Akcay, Sule; 0000-0002-3628-4661; 0000-0002-2557-9579; 0000-0002-8360-6459; 0000-0003-3225-2686; 0000-0002-4171-7484; 32584234; AAN-5153-2021; S-6973-2016; AAI-8069-2021; AAB-5175-2021; AAD-5602-2021; AAI-8947-2021OBJECTIVES: Since many similar mechanisms may play a role in the pathophysiology of sarcoidosis and atherosclerosis, the risk of subclinical atherosclerosis may be increased in patients with sarcoidosis. The aim of this study was to evaluate known markers of subclinical atherosclerosis, namely epicardial fat thickness (EFT) and carotid intima-media thickness (CIMT) in patients with sarcoidosis. MATERIALS AND METHODS: This cross-sectional study included a total of 183 subjects, including 94 patients with sarcoidosis (patient group) and a control group of 89 healthy individuals. Measurements of EFT and CIMT were taken from all subjects and recorded. The groups were compared, and differences were analyzed statistically. RESULTS: EFT was higher in patients than in control subjects (6.42 +/- 1.12 mm vs 7.13 +/- 1.41 mm, p<0.001). CIMT was higher in patients than in control subjects (0.51 +/- 0.02 mm vs 0.52 +/- 0.02 mm, p=0.003). CONCLUSION: EFT and CIMT were found to be higher in patients with sarcoidosis than in healthy people. These results indicate that the risk of subclinical atherosclerosis might be increased in these patients.Item Change of respiratory functions, the STOP-Bang questionnaire, and Epworth sleepiness scale after bariatric surgery(2020) Kara, Sibel; Habesoglu, Mehmet Ali; Yabanoglu, Hakan; 33055387INTRODUCTION AND OBJECTIVE: Obesity is a highly morbid and fatal syndrome that reduces respiratory function. Obstructive sleep apnea syndrome (OSAS) is a common sleep disorder in morbid obesity. Herein, we aimed to determine how respiratory function tests changed over time after bariatric surgery and to assess non-PSG (polysomnography) tests, namely STOP-Bang questionnaire and Epworth sleepiness tests, for predicting OSAS risk. METHOD: This retrospectively conducted study enrolled 35 patients who underwent bariatric surgery. Patients were divided into three groups formed on the basis of time passed after surgery (1, 2, or 3 years). Preoperative and postoperative respiratory function test parameters assessed by spirometry, body mass index (BMI), STOP-Bang questionnaire, and Epworth sleepiness test scores were recorded. RESULTS: Twenty-four (68.6%) patients were female, 11 (31.4%) male. The mean age was 36.5 +/- 10.5 years. Postoperative weight loss of the study groups was 26% p=0.001, 23.6% p=0.002 and 25.9% p=0.005. Reductions in BMI were 32 kg/m(2) p=0.001, 34.5 kg/m(2) p=0.002, 35.8 kg/m(2) p=0.005 respectively. Postoperative FVC (440 ml, 390 ml, 430 ml p = 0.005) and FEV1 (220 ml p = 0.005, 250 ml p = 0.004, 214 ml p = 0.005) increased in all three groups. STOP-Bang questionnaire and Epworth sleepiness scale scores significantly decreased after weight loss compared to preoperative period in all the study groups. CONCLUSION: We showed that FVC and FEV1 increased in the short and long term after weight loss by bariatric surgery; we also found that STOP-Bang questionnaire and Epworth sleepiness scale scores decreased postoperatively. These tests may be helpful to assess OSAS risk before and after surgery.Item Comparative analysis of the patients with community-acquired pneumonia (CAP) and health care-associated pneumonia (HCAP) requiring hospitalization(2019) Kara, Sibel; Akcay, Muserref Sule; Ekici, Unsal Zuhal; Bozkurt Yilmaz, Hatice Eylul; Habesoglu, Mehmet Ali; 31414641Introduction: The recently introduced concept of health care-associated pneumonia (HCAP), referring to patients with frequent healthcare contacts and at higher risk of contracting resistant pathogens is controversial. Materials and Methods: A prospective study comparing patients with HCAP and community-acquired pneumonia (CAP) in the our center. The primary outcome was 30 day mortality. Results: A total of the 169 patients HCAP 36 (21.3%); CAP 133 (78.7%) were evaluated. HCAP patients were older than patients with CAP [median age was 72.5 (43-96), 60.0 (18-91) years p< 0.05]. The most common Klebsiella pneumoniae (16.6%) and Pseudomonas aeruginosa (8.3%) were gram-negative bacteria in the SBIP group; In the TGP group, gram-positive bacteria were more frequently isolated. Polymicrobial agents (22.2% vs. 3.7% p< 0.05) and MDR pathogens (57.1% vs. 24% p< 0.05) were more common in patients with HCAP. Mortality rate (22.2% vs. 6% p< 0.05) was also higher in HCAP more than CAP. Conclusion: HCAP was common among patients with pneumonia requiring hospitalization and mortality rate was high. The patients with HCAP were different from CAP in terms of demographic and clinical features, etiology, outcome.Item Congenital Bronchial Artery - Pulmonary Artery Fistula in a Young Adult(2015) Kara, Sibel; Sen, Nazan; Ozkan, Ugur; Akcay, M.SulePrimary vascular malformations such as connection between bronchial artery and pulmonary artery or pulmonary vein are quite rare. A 18-year-old male patient with the first episode of massive hemoptysis was found to have bronchial artery-pulmonary artery fistula, a rare vascular anomaly, on selective bronchial angiography. Since medical history revealed no acquired cause, it is considered congenital. He underwent bronchial artery embolization and hemoptysis was completely resolved after endovascular treatment. The presence of such vascular anomalies should be suspected in patients with massive hemoptysis. Bronchial artery embolization is a safe and effective nonsurgical treatment option for such patients.
