    A Bibliometric Overview on Endovenous Laser Ablation Research
    (Cem TIRINK, 2023) Şahin, Serpil
    In managing saphenous vein reflux, endovenous laser ablation (EVLA) has emerged as a trendy minimally invasive substitute in recent years. The development of this field benefits from a thorough understanding of its state of development, and bibliometric analysis may help this. However, no bibliometric analysis has adequately summed up this field. In this study, we sought to analyze decades' worth of EVLA literature. The present study aimed to retrieve information from journals listed in the Web of Science (WoS) search engine with the dataset "TI= (EVLA) or TI= (Endovenous Laser Ablation)." We searched the WoS core collection. There were 471 publications (70.701% articles). They were cited 8062 times totally and 17.12 times per article. The mean Hirsch (H) index of the published documents was 49. Over the past 20 years, there has been a gradual rise in the number of publications and citations in EVLA research, suggesting that the field has gained attention. The United States of America (USA) (n=99), England (n=48), Netherlands (n=48), Türkiye (n=46), and Germany (n=40) were the top five publishing countries on EVLA research. The findings showed that the number of published documents was limited. The contribution was only from 46 countries. The number of publications and the number of broadcasting countries should be increased

    Contribution of Turkey in Heart Transplant Research: A Web of Science Database Search
    (Baskent University, 2023) Şahin, Serpil; Alkan, Sevil
    Objectives: In 2001, Turkey performed its the first successful heart transplant. Since 2011, 765 heart transplants have been conducted among 15 heart transplant centers. The scientific impact of Turkish articles on heart transplantation remains uncertain. The purpose of this study was to evaluate Turkey’s contributions in international heart transplant research. Materials and Methods: The bibliometric study approach was used to assess publications on heart transplantation, which included analysis of year of publication, organizations/authors, sponsorship, keywords, citations, and other characteristics. Titles, abstracts, and key words were searched in the Web of Science database for terms that included “heart” or “cardiac” and “transplantation.” Methods for both quantitative and qualitative data analysis were used. Results: During the analysis period of 1970 through 2021, 6370 article publications were retrieved with an average of 20.88 citations/article and 133 018 total citations. H index was 129. Most of the retrieved articles were from research areas of surgery (n = 2876; 45.14%), followed by transplantation (n = 2818; 44.23%) and cardiovascular system cardiology (n = 2522; 39.59%). Annual citation growth showed slow growth until 1986. The highest number of citations was seen in 2021 (n = 702). The United States led countries on articles (n = 2924; 45.9%), followed by Germany (n = 458; 7.19%), England (n = 411; 6.45%), Canada (n = 384; 6.02%), France (n = 330; 5.18%), and Spain (n = 329; 5.16%). The other 84 countries totaled 753 (11.82%) articles. Turkey ranked eighteenth with 87 publications, with Başkent University (n = 37) and Ege University (n = 13) being the leading centers on heart transplant research in Turkey. Conclusions: Publications from the United States continue to increase. The workload of both transplant surgery and research and publishing is challenging and Turkish researchers are encouraged to make strides at innovations.

    Amaç: Diyabet ve damar hastalıkları, diyabetik ayak enfeksiyonu (DAE) ve alt ekstremite amputasyonu riskini artırır. DAE risk faktörleri ve mikrobiyolojik analizler kapsamlı bir şekilde araştırılmış olmasına rağmen, bu özel grup için veriler sınırlıdır. Bu çalışmada DAE tanısı ile takip ve tedavi edilen hastaların altta yatan vasküler risk faktörlerinin ve klinik sonuçlarının incelenmesi amaçlandı. Yöntemler: 2016-2021 yılları arasında DAE için merkezimize başvuran 153 hastanın klinik, demografik, laboratuvar, mikrobiyolojik ve ayak muayene verileri hastane bilgi sisteminden geriye dönük olarak toplandı. Bulgular: Mevcut merkez, bu süre içinde 5 yıl boyunca toplam 153 DFI hastası topladı. Yaş ortalaması 67.71±15 yıl olan 86 erkek ve 67 kadın hasta vardı. Vasküler kaynaklı olmayan DAE grubunda 104, vasküler kaynaklı DAE grubunda 49 hasta vardı. DAE hastalarının ilk iki komorbiditesi sırasıyla kardiyovasküler hastalık ve hipertansiyondu. Vasküler kaynaklı DAE grubunda erkek hasta oranı istatistiksel olarak daha yüksekti (p=0,003). Ayrıca vasküler kaynaklı DFI grubunda hipertansiyon ve kardiyovasküler hastalık daha sıktı (p=0.0006, p=0.01). Ekstremite amputasyonu/debridman öyküsü, Wagner grade 5 DAE ve doku kültürlerinde Gram negatif mikroorganizma üremesi vasküler kaynaklı DAE grubunda daha sıktı (p=0.01, p=0.01 ve p=0.0006). Vasküler kaynaklı DAE grubunda ekstremite amputasyon/debridman oranları daha yüksekti (p=0.01) Sonuç: DAE’ları, yüksek ampütasyon riski, uzun süreli antibiyotik tedavisi, artan hastane yatışı ve tetkikler sonucu artan sağlık maliyetlerine neden olur. DAE’larının altında yatan vasküler patolojilerin farkındalığı, klinisyenlerin hastalığı yönetmesine yardımcı olabilir. Bu çalışmada amaç vasküler faktörlerin önemini vurgulamaktadır

    Gallic acid encapsulated pea flour-based nanofibers produced by electrospinning as a potential active food packaging material
    (John Wiley and Sons Inc, 2021) Aydoğdu Emir, Ayca; Yıldız, Eda; Aydoğdu, Yıldırım; Sumnu, Gülüm; Şahin, Serpil
    The main aim of the article was to produce gallic acid-loaded pea flour/polyethylene oxide (PEO)-based nanofibers through the electrospinning method as an alternative active packaging material. Incorporation of gallic acid caused significant changes in both solution properties and fiber morphology. Increasing gallic acid concentration resulted in increasing conductivity and decreasing consistency index, by the way decreasing average fiber size diameter. In thermogravimetric analysis (TGA), gallic acid addition resulted in a decrease in thermal degradation value of nanofibers. In addition to these changes, new chemical bands formed were an indicator of the successful encapsulation of gallic acid in Fourier-transform infrared (FTIR) spectra. Nanofibers also showed promising results in terms of encapsulation of bioactive compounds. Therefore, gallic acid-loaded pea flour/PEO-based nanofibers might be considered as a promising active packaging material.

    (Mesut TUZLALI, 2022) Alkan, Sevil; Gürbüz, Esra; Şahin, Serpil; Özlü, Can; Şahinoğlu, Mustafa Serhat
    Although it was known that the most common route of transmission for hepatitis E virus (HEV) was the fecal-oral route in previous years, the possibility of transmission by blood transfusion has been advocated by many researchers recently. This transmission is thought to cause mild to modarate hepatitis, especially in immunosuppressive patients. It has been reported that especially HEV Genotype 3 is transmitted in blood transfusion. In this study, it was aimed to review the global literature in terms of HEV transmitted by blood transfusion

    (Mesut TUZLALI, 2022) Şahin, Serpil; Şahinoğlu, Mustafa Serhat; Alkan, Sevil
    Aort vücudun ana damarı olup, bu damar bazı enfeksiyöz ve non enfeksiyöz hastalıkların seyri sırasında tutulabilir. Aort duvarının inflamasyonu aortit olarak tanımlanmaktadır. Aortit; yaşamı tehdit edebilen bir acil olup insidansı gerek çocuklarda gerekse de erişkinlerde oldukça düşüktür. Aortitin tanımlanmış enfeksiyöz nedenleri arasında salmonelloz, sifiliz gibi enfeksiyöz hastalıklar bulunmaktadır. İnsan brusellozu, birçok organ sisteminde komplikasyonlar oluşturabilen, sistemik enfeksiyon tablosunun yanı sıra fokal hastalık tabloları ile de karşımıza çıkabilen zoonotik bir hastalıktır. Bununla birlikte, brusellozun nadir bir komplikasyonu olarak aort tutulumu olan hastalarda klinik özellikler, terapötik yaklaşımlar gibi birçok konu hakkında çok az şey bilinmektedir. Biz de bu çalışmada, aort tutulumu olan bruselloz olgularını literatür eşliğinde derlemeyi amaçladık

    (2023) Şahin, Serpil; Altınışık, Hatice Betül; Çeviker, Sevil Alkan; Küçük, Uğur; Çinpolat, Havva Yasemin; Gönlügür, Uğur
    Aim: In this study, we sought to determine patient characteristics and clinical outcomes of patients who experience this complication, as well as the frequency of thromboembolic events (TEE) in COVID-19 patients hospitalized. Materials and Methods: Between January 2020 and December 2021, all the patients with positive COVID-19 PCR test results were enrolled in this study. The data of the cases that developed TEE with the diagnosis of COVID-19 were evaluated retrospectively. Results:During this time, 2,845 inpatients were admitted with COVID-19. Among this group, 96 patients (3.37%) had COVID-19 - related TEE. The mean age was 63.76±13.85 years (range, 28–80 years) with 46 men (47.92%) and 50 women (52.08%). Of the patients, 46 of 96 (47.92%) had severe COVID-19, and 50 of 96 (52.08%) had only mild respiratory symptoms. Severe COVID-19 group patients were older but there was not statistically significance between the groups. Peripheral venous disease was more common in mild COVID-19 group, while peripheral arterial disease is more common in severe COVID-19 group.CRP, uric acid, troponin, creatinine,D-dimer and leukocyte levels were higher in severe COVID-19 patients with TEE (p<0.05). Peripheral venous disease was present in 81 of 96 (84.37%), peripheral arterial disease in 5 of 96 (5.2%), and pulmonary embolism in 11 (11.45%) cases. One patient (1.04%) had both peripheral venous disease and pulmonary embolism. The overall mortality was 6.25% (6/96). Conclusion: COVID-19-associated thrombotic process affects more frequently veins than arteries. Given the significant observed risk for TEE in COVID-19, diagnostic imaging for TEE should be evaluated with a high degree of clinical suspicion.

    Investigation of Venous Thromboembolism Prophylaxis Practices in Spinal Fusion Surgery and Outcomes: A Single Center Experience
    (Rabia YILMAZ, 2023) Akar, Ali; Şahin, Serpil
    Abstract Aim: Venous thromboembolism (VTE) is among the most common causes of preventable hospital-acquired deaths. VTE is known as deep vein thrombosis (DVT) when it occurs in the veins and pulmonary embolism (PE) when it occurs in the lungs and is common in surgery practice. We aimed to determine the frequency of venous thromboembolism (VTE), the factors affecting the development of VTE, and the types and effectiveness of VTE prophylaxis applications in patients who underwent spinal fusion surgery (SFS). Material and Methods: The patients aged over 18 who underwent SFS for spinal fracture or thoracolumbar stenosis in our neurosurgery clinic between June, 2020 and December, 2022 were included. The patients records were evaluated retrospectively. VTE prophylaxis was given according to the Caprini risk score. Results: A total of 137 patients, 85 (62%) of female, with a meanage of 48.6±+8.77 years were included in the study. According to the Caprini risk scores, 90 (65.7%) of the cases were at high risk. VTE was detected in four patients (2.9%) despite prophylaxis (3 cases of DVT and one pulmonary embolism). Conclusions: Although VTE prophylaxis is performed according to Carpini risk score in SFS, it is seen that embolisms cannot be prevented sufficiently. Therefore, studies with a high level of evidence are needed for the use of these algorithms in SFS

    Predicting New-Onset Atrial Fibrillation in Patients with Coronary Artery Bypass Graft: the Precise-Dapt Score
    (National Scientific Medical Center, 2024) Küçük, Uğur; Şahin, Serpil
    Aim: Postoperative new-onset atrial fibrillation (POAF) after isolated coronary artery bypass graft surgery (CABG) is associated with adverse events. The Predicting bleeding complications in patients undergoing stent implantation and subsequent dual antiplatelet therapy (PRECISE-DAPT) score is used to predict the bleeding risk after dual antiplatelet therapy and has been associated with arrhythmias in recent years. Therefore, the present study sought to investigate the association between the PRECISE-DAPT score and POAF after coronary artery bypass graft surgery. Materials and methods: 350 patients who underwent CABG were retrospectively screened. After exclusion criteria, 135 patients were included in the study. A total of 135 patients who underwent on-pump CABG were divided into two groups: patients with POAF and those without POAF. The PRECISE-DAPT score was calculated for each patient, and intergroup comparisons of the calculated scores were performed. Results: POAF was detected in 66 patients out of 135. Patients with POAF had longer hospital stays. PRECISE-DAPT score was higher in the patients with POAF compared to the patients without POAF (p<0.001). PRECISE-DAPT score was determined to be a predictor of POAF after CABG (odds ratio [OR]: 1.305; 95% confidence interval [CI]: 1.268–2.030; p<0.001). The PRECISE-DAPT score for POAF risk had a sensitivity of 60% and a specificity of 79% at cut-off values of 14.5 and above. Conclusion: An increased PRECISE-DAPT score may be used as a predictive score for POAF that may develop during hospital stay after on-pump CABG. © 2024, National Scientific Medical Center.

    Research trends and top cited articles on the frozen elephant trunk procedure
    (2022) Şahin, Serpil
    ABSTRACT Background: Bibliometric studies can direct academics. There have been many specialties and subspecialties where bibliometric analyses have been published, but our literature search yielded no bibliometric analysis of the frozen elephant trunk (FET) procedure. The primary objective of this study was to identify the most frequently referenced papers on FET procedure research and investigate the research trends. Methods: A dataset of all scientific journals published in the English language was created using the Web of Science (WOS) database. This search was then cross-referenced with a comparable search phrase query of the Scopus Library database in order to locate any publications that could have been overlooked during the first search. Citation counts were used to rank the articles. Also knowledge maps were created using VOSviewer software, and articles and reviews pertaining to the FET procedure in CVDs were taken from the WOS Core Collection. Results: A total of 484 documents on Scopus and 494 documents on WOSpertaining to the FET procedure were included in this study. The leading countries that published most of the research were Germany, Japan, and Italy in both databases. The largest subset of the FET procedure articles was published since 2012. The most cited authors were Karck, Shrestha, and Uchida. The mean Hirsch index of the articles was 40 and 10.47 per article. Conclusion:This study offers information on the traits and standards of the FET procedure literature that has received the most citations, as well as a ranking of the most important sources for this procedure. This work provides as a guide to what constitutes a citeable FET procedure publication by offering the most important references and mostly publishing journals.

    THE CORRELATION BETWEEN BRUGADA SYNDROME/ BRUGADA PATTERN AND FEVER
    (Mesut TUZLALI, 2023) Şahin, Serpil; Alkan, Sevil; Küçük, Uğur; Şahinoğlu, Mustafa Serhat
    Brugada syndrome is a hereditary cardiac sodium channelopathy that is autosomal dominant. Despite having a structurally normal heart, people with Brugada syndrome have an increased risk of sudden cardiac death. The electrocardiogram (ECG) pattern used for diagnosis can be seen either spontaneously or during a sodium channel blocker test. Despite recent findings from sizable population cohorts, risk stratification among affected patients is still difficult. Numerous risk factors for stratifying the risk of sudden cardiac death in Brugada syndrome have recently been proposed. The Brugada pattern is defined as a significant coved or saddle-shaped ST-segment elevation followed by T wave shifts in V1–V3 and without any other obvious explanation. Brugada syndrome or Brugada pattern can be occasionally precipitated by fever and several infections. In this review, our goal was to examine the literature in relation to Brugada syndrome/ Brugada pattern and fever

    THROMBOANJITIS OBLITERANS(BUERGER‘S DISEASE)
    (Mesut TUZLALI, 2022) Şahin, Serpil
    Thromboangiitis obliterans (TAO) is a non-atherosclerotic segmental inflammatory disease.It affects small and medium-sized arteries and veins in the upper and lower extremities. Cigarette smoke is the main etiology of the disease. As the rate of smoking increases worldwide, so does the number of patients with TAO. Never treatment modalities have shown promising results.These treatments help in reducing pain, the healing of trophic changes, the increase in pain-free walking distance, decreasing the need for major amputations and an overall improvement in quality of life. However,long-term treatments all fail in preventing the diseases’ progression in patients who continue to smoke.With the global increase in smoking in mind, a review of current literature on TAO has been carried out with a focus on modern treatments

    Usefulness of red cell distribution width as a predictor of amputation after embolectomy in acute lower limb ischemia
    (2023) Şahin, Serpil; Taşoğlu, İrfan
    Objectives: This study aimed to determine whether red cell distribution width (RDW) is an independent predictor of adverse outcomes in patients who underwent surgical embolectomy for acute lower limb ischemia. Patients and methods: This retrospective study included 245 patients who underwent surgical embolectomy for acute lower limb ischemia between January 2008 and June 2012. Patients who had thrombosis of the atherosclerotic lesion and iliac or femoral stent thrombosis were excluded. The patients were divided into two groups according to the need for limb amputation after the initial embolectomy: 42 were in the limb amputation group (33 males, 9 females; mean age: 67.2±9.1 years; range, 52 to 85 years), and 203 were in the limb salvage group (132 males, 71 females; mean age: 58.4±9.3 years; range, 44 to 71 years). A multinomial logistic regression analysis was applied to determine the independent predictive effect of RDW and other parameters on major/minor amputation. The analysis was multivariately adjusted for age and sex to eliminate the confounding effect of other variables. Results: Age (odds ratio [OR]=1.131, 95% confidence interval [CI]: 1.074-1.191, p<0.001), recurrent embolism in the same limb (OR=2.898, 95% CI: 1.238-6.780, p=0.01), urea level (OR=1.037, 95% CI: 1.013-1.062, p=0.003), and RDW (OR=1.324, 95% CI: 1.006-1.741, p=0.04) were significantly associated with the risk of major amputation in unadjusted multinominal logistic regression analysis, whereas the association of RDW with the risk of major amputation did not remain when adjusted for age and sex (OR=1.191, 95% CI: 0.963-1.474, p=0.10). Conclusion: In conclusion, RDW may have a role in predicting adverse outcomes in patients treated for acute lower limb ischemia. However, it cannot be used as a stand-alone predictive marker.

    Vascular Access for Dialysis
    (Nova Science Publishers, Inc., 2025) Şahin, Serpil; Şahin, Ozgur
    Hemodialysis is a critical treatment and one of the major medical advancements for the survival of patients with chronic renal failure. The effectiveness of this treatment is closely linked to the provision and maintenance of suitable vascular access routes. The vascular tract playsacrucialrole in hemodialysis treatment by providing the necessary blood supply. For this reason, vascular tract expertiseis vital for hemodialysis and is often referred to asthe "life path," "life way" and "green tendon." Advances in health and technology, especially in vascular surgery, have provideddialysis patients with recent renal failure the opportunity to undergo dialysis for many years and, significantly extend their lifespan. The life expectancy of hemodialysis patients varies depending on adequate dialysis, the minimum possible occurrence of vascular complications, and the continuity of a healthy vascular tract. Therefore, good planning and policies need to be developed to keep the vascular tract healthy. Key initiatives in this regard include the preparation of arteriovenous fistulas prior to dialysis, the training of patients and healthcare personnel, successful and appropriate vascular tract surgeries, the preservation of arm circulation, the monitoringof vascular problems, and the development of short-term solutions and interventions these issues. Academic research over the past 10 years has focused on various innovations and improvements to improve the effectiveness of the vascular entrance pathways used for hemodialysis and minimize complications. This section presents an assessment of important academic studies in the last 10 years on vascular entrance routes and their selection for hemodi alysis. © 2026 Nova Science Publishers, Inc.
