Abstract
INTRODUCTION Cold agglutinin disease (CAD) is a rare autoimmune disorder characterized by destruction (hemolysis) of erythrocytes. In CAD, autoantibodies that cause agglutination at temperature of optimum +3-+4 ℃ degree cause symptoms. It is known that CAD often occurs after viral infections. Also, it has been reported in case reports that COVID-19 disease can cause CAD. CASE REPORT 46-year-old male patient with a history of diabetes mellitus and hypertension presented to outpatient clinic in our department to have CABG surgery. He recovered from COVID-19 disease 1.5 months ago. Cardiopulmonary bypass was initiated and the cross-clamp was placed and antegrade Delnido cardioplegia solution was started to be given at +4 ℃. It was observed that the cardioplegia line was agglutinated. On the other hand, it was seen that the autologous blood taken by the anesthesiologist was also agglutinated and formed air bubbles and became unusable. X-clamp was removed and the heart rhythm recovered. The patient was consulted to hematology during postoperative intensive care follow-ups. The cold agglutinin test performed at of +4 ℃ was reported as positive. In this case, we associated the CAD with covid-19 for three main reasons. First one, the patient's complaints about CAD started after COVID-19 disease. Secondly, in the national health archive, the patient's pre-COVID-19 blood tests were completely normal but it was seen that LDH increased and RBC-HCT incompatibility started after COVID-19. As the third, when we search the literature, we have seen the COVID-19 related CAD in many case reports published by hematologists. CONCLUSION With the rare cold agglutinin disease, it seems that we will encounter it more often after the COVID-19 pandemic. Except for deep hypothermia, the most important problem is seen during cardioplegia administration. Therefore, non-blood cardioplegia can be lifesaving.

Abstract
INTRODUCTION Anemia and transfusion of blood products are risk factors associated with poor patient outcomes across all elective surgeries. Patient blood management (PBM) is a patient-centered approach to optimize patient's endogenous red cell mass, to minimize blood loss in patients undergoing surgery, and to harness and optimize patient-specific physiological tolerance to anemia. This study aimed to assess (1) the impact of PBM on blood product usage in cardiovascular surgeries in a state hospital setting, (2) cost-effectiveness of PBM with a model based on transfusion of red blood cells (RBCs) in cardiovascular surgeries, and (3) the budget impact of PBM implementation based on transfusion of RBCs. METHODS Cost-effectiveness and budget impact models, based on the numbers of avoided transfusions and avoided complications after implementation of the PBM program, were compared between pre- and post-PBM periods at the cardiovascular surgery department of Ankara Bilkent City Hospital between February 11, 2019 and July 24, 2022. The probabilities of transfusions and complications with and without PBM were taken from recent meta-analyses. Data from the Ankara Bilkent City Hospital transfusion center informed the pre- and post-PBM calculations. Costs were calculated from the Social Security Institution's perspective. RESULTS There was a 21% decrease in the use of RBCs and a 23.7% decrease in use of all blood products after the implementation of PBM. The number of RBC packs per patient reduced by 0.88 packs (21%). The cost saving from reduction of RBC transfusions per patient was 518.68 Turkish lira (TRY) and for the hospital it was 1,635,948 TRY. Fewer complications and lower costs in favor of the post-PBM arm were demonstrated in the cost-effectiveness analysis. On the basis of the budget impact model, in 20 months, the hospital's cardiovascular surgery department saved 6,596,934 TRY (€342,302). CONCLUSION This hospital-based study demonstrated that PBM is a budget-saving and cost-effective option in Turkey.

Abstract
Objective Perioperative multimodal analgesia is an important step in enhanced recovery after surgery (ERAS) care. Many factors, such as preoperative chronic pain and anxiety, may provide information about the expected postoperative pain. In this study, we evaluated preoperative pain and anxiety and investigate their effects on acute postoperative pain in patients undergoing elective cardiac surgery. Methods After ethics committee approval, 67 consenting patients undergoing on-pump cardiac surgery under the ERAS program were included in our prospective observational study. Pre- and postoperative pain scores were obtained using a numeric rating scale (NRS) at rest and during movement. Preoperative anxiety was assessed on a 0-10 scale, and data were recorded. The relationships between pre-operative pain/anxiety and postoperative pain were evaluated using correlation analysis. Results In preoperative pain assessment, the percentage of patients with a pain score above 4 with NRS was 1.5%, regardless of whether they were at rest or mobilize. In postoperative pain assessment, there were 20.9% and 34.3% patients with NRS >4 at rest and mobilization, respectively. 7.5% of patients had preoperative anxiety of grade 5 or higher. While preoperative pain was not correlated with postoperative pain, preoperative anxiety had a moderate positive correlation with postoperative pain (r=0.382, P=0.003). Conclusion The prevalence of preoperative pain in patients who underwent cardiac surgery is quite low and is not associated with postoperative pain. There is also a significant relationship between the severity of preoperative anxiety and postoperative pain.

Abstract
OBJECTIVE To compare the results of endovascular therapy for chronic limb-threatening ischemia (CLTI) in patients categorized under the gray and yellow zones of the patient risk, limb severity, and anatomic pattern (PLAN) concept over a 2-year follow-up period. METHODS Patients who underwent endovascular therapy for peripheral artery disease and presented with CLTI from February 2017 to February 2019 were retrospectively reviewed. The patients were grouped into yellow and gray zones based on the PLAN concept. Preoperative and postoperative walking distances, Rutherford classes, and postoperative target vessel patency rates were recorded and compared between the groups. Follow-up evaluations were performed at 1, 6, 12, and 24 months post-procedure. RESULTS Of the 387 patients evaluated, the yellow and gray groups comprised 88 patients each. The overall patency rates were similar between the groups (84 (95.45%) vs. 81 (92.05%), respectively). The occlusion-/stenosis-free survival times, amputation-free survival time, and mean survival time were not significantly different. However, the gray group had a significantly higher number of atherectomy interventions (74 vs. 59) and crosser devices used (62 vs. 42). CONCLUSION Endovascular therapy is an effective treatment option for patients in the gray zone of the PLAN color coding system.

Abstract
BACKGROUND Clinical evidence is commonly obtained through individual trials that are time-, cost- and resource-consuming, and which often leave unanswered clinically relevant questions. Umbrella studies have been developed to address the need for more efficient and flexible trial structures, predominantly for cancer treatments. The umbrella concept foresees data collection within a unifying trial structure, to which one or more substudies may be added at any time to address product- or therapy-specific questions. To our knowledge, the umbrella concept has not yet been used in the medical device area, but it may offer similar advantages as in other settings, particularly in areas where multiple therapies are available within one large treatment area. METHODS The MANTRA study (NCT05002543) is a prospective, global, post-marketing clinical follow-up study. The aim is to collect safety and device performance data covering the Corcym cardiac surgery portfolio for the treatment of aortic, mitral, and tricuspid valve diseases. The study uses a master protocol that outlines the main common parameters, and the specific questions are addressed in three substudies. The primary endpoints are device success at 30 days. Secondary endpoints include safety- and device performance-related data at 30 days, 1 year, and then annually through to 10 years. All endpoints are defined according to the more recent guidelines for heart valve procedures. Additionally, procedure and hospitalization information are collected, including Enhanced Recovery after Surgery in sites using such protocols, and patient outcome measures such as New York Heart Association classification and quality-of-life questionnaires. RESULTS The study started in June 2021. Enrollment in all three substudies is ongoing. CONCLUSIONS The MANTRA study will provide contemporary information on the long-term outcomes of medical devices for the treatment of aortic, mitral, and tricuspid heart valve diseases in routine clinical practice. The umbrella approach adopted in the study has the potential of longitudinally assessing long-term efficacy of the devices and the flexibility to investigate new research questions as they arise.

Abstract
In this study, magnetic poly(ethylene glycol dimethacrylate-N-methacryloyl-(L)-glutamic acid) (mPEGDMA-MAGA) particles were prepared by the dispersion polymerization in order to purify thrombin effectively. mPEGDMA-MAGA particles were synthesized by adding different ratios of magnetite (Fe3O4) to the medium in addition to the monomer phases EGDMA and MAGA. The characterization studies of mPEGDMA-MAGA particles were used by fourier transform infrared spectroscopy, zeta size measurement, scanning electron microscopy and electron spin resonance. mPEGDMA-MAGA particles were used in thrombin adsorption studies from aqueous thrombin solutions in both batch and magnetically stabilized fluidized bed (MSFB) system. Maximum adsorption capacity in pH 7.4 phosphate buffer solution is 964 IU/g polymer and 134 IU/g polymer in MSFB system and batch system, respectively. The developed magnetic affinity particles enabled the separation of thrombin from different patient serum samples in one step. It has also been observed that magnetic particles can be used repeatedly without significant reduction in adsorption capacity.

Abstract
In this study, it is aimed to determine cardiac troponin I by a surface plasmon resonance biosensor immobilized anti-cardiac troponin I monoclonal antibody. The immobilized anti-cardiac troponin I monoclonal antibody surface plasmon resonance biosensors were characterized with ellipsometry, atomic force microscopy and contact angle analysis. After that, surface plasmon resonance biosensor system was completed to biosensor system to investigate kinetic properties for cardiac tropinin I. The sensing ability of surface plasmon resonance biosensor was investigated with 0.001-8.0 ng/mL concentrations of cardiac tropinin I solutions. The limit of detection and limit of quantification were calculated as 0.00012 ng/mL and 0.00041 ng/mL, respectively. To show the selectivity of surface plasmon resonance biosensor competitive adsorption of cardiac tropinin I, myoglobin, immunoglobulin G and prostate specific antigen were investigated. Surface plasmon resonance biosensor was investigated five times with 0.5 ng/mL concentrations of cardiac tropinin I solution to show reuse of the chip. The results showed that surface plasmon resonance biosensor has high selectivity for cardiac tropinin I. The reproducibility of surface plasmon resonance sensors was investigated both on the same day and on different days for five times. To determine the usability, selectivity and validation studies of surface plasmon resonance biosensors were performed by enzyme-linked immunosorbent assay method.

Abstract
In the human body, vascular injuries that are caused by trauma, vessel lumen stenosis, and occlusions are often irreversible and can lead to sequelae formation as the vessels cannot reproduce fast enough. To solve this problem, the blood flow must be returned to the region as fast as possible. The adipose tissue contains progenitor cells with angiogenic potential and can be used to resolve the issue. In the present study, mesenchymal stem cells (MSCs) derived from rat adipose tissue, vascular endothelial growth factor (VEGF), and their mixture were applied on the dorsum of a rat, which was traumatized and its contribution to vascular regeneration was reviewed. No application was made to the control group. The results showed that the percentage of necrotic area was significantly lower in the MSC group than that of all the other groups. When the VEGF group was compared to the VEGF + MSCs, the percentage of necrotic area was observed to be similiar. However, VEGF showed effects only when a large quantites of VEGF was applied to the flap area. VEGF could not fully respond to the needs, whereas MSCs can produce VEGF according to the needs of tissue. This makes them superior to stem cells.
