- Abstract
OBJECTIVE: Anastomotic leakage is a complication that creates significant concern in terms of postoperative morbidity and mortality after colorectal surgery. This study aimed to identify variables for detecting anastomotic leakage in those who had open, laparoscopic, or robotic low anterior resection for cancer and to explore their relationships. PATIENTS AND METHODS: A total of 283 patients who were diagnosed with rectal cancer and underwent low anterior resection were divided into two groups: those with and without anastomotic leakage. Demographic and clinical data were analyzed. Anastomotic leakage was detected in 23 of 283 patients who underwent low anterior resection. RESULTS: The postoperative analysis of the biochemical data of the patients showed statistically significant differences between the two groups in terms of C-reactive protein (Crp), albumin, lymphocytes, leukocytes, neutrophils, and their ratio. The performance of these parameters in predicting anastomotic leakage was statistically analyzed in the patient group with anastomotic leakage, and nomogram results were acquired. Immune system components and biomarkers were statistically tested, and nomogram results were obtained in rectal cancer patients. CONCLUSIONS: These parameters can be used together as a potential marker in anastomotic leakage. Further development of these variables has the potential to facilitate the timely detection and treatment of anastomotic leakage. [ABSTRACT FROM AUTHOR]

- Abstract
OBJECTIVE: There is no study that compares the diagnostic performance of ATV and ESV techniques in detecting cleft palate. We aimed to evaluate the diagnostic accuracy of two ultrasound techniques: axial-transverse (ATV) and "equal sign" view (ESV), in detecting fetal cleft palate without cleft lip. PATIENTS AND METHODS: This prospective study was conducted from March 2019 to January 2022 in a tertiary referral hospital. Secondary palates were assessed with ATV and ESV by two experienced fetal medicine specialists who were blinded to each other's ultrasound findings. Final diagnosis was done according to postnatal physical examination. The sensitivity and specificity of the two techniques were calculated. RESULTS: A total of 311 pregnancies which met the study criteria were evaluated. Postnatal physical examination showed that 13 (0.4%) neonates had cleft palate only (CPO). According to final diagnosis the sensitivity, specificity, positive predictive value and negative predictive value for ATV were 100%, 98.7%, 76.4%, 100% and 100% for ESV were 76.9%, 97.8%, 58.9% and 99%, respectively. CONCLUSIONS: ATV in 2D ultrasound provides higher sensitivity and specificity than ESV in detecting CPO. [ABSTRACT FROM AUTHOR]

- Abstract
OBJECTIVE: Aspirin is an essential drug in the prevention of atherosclerotic cardiovascular disease (ASCVD). It is ultimately indicated in a patient with ASCVD. However, its role is debated in primary prevention. We aimed to investigate the appropriateness of aspirin use in diabetic patients according to recommendations of recent guidelines. PATIENTS AND METHODS: ASSOS was a multicenter observational study investigating aspirin use in cardiology outpatient clinics. We evaluated aspirin use in diabetic patients in primary prevention from the ASSOS study. We also assessed the appropriate use of aspirin according to the European Society of Cardiology (ESC), American College of Cardiology/American Heart Association (ACC/AHA), American Diabetes Association (ADA), Consensus Statement of Endocrinology, Cardiology, and Nephrology (ENCARNE), and the United States Preventive Services Task Force (USPTF). RESULTS: A total of 5,007 patients of whom 1,537 had type 2 diabetes mellitus (DM) were included in the study. 1,132 of the total participants used aspirin for primary prevention; 313 of them had type 2 DM. Only 248 (76.7%), 132 (40.8%), and 128 (39.6%) diabetic patients indicated aspirin use according to the ESC/INCARNE, ACC/AHA, and ADA/USPTF guidelines, respectively. CONCLUSIONS: Inappropriate aspirin use was common among diabetic patients, according to clinical practice guideline recommendations. In addition, the differences between the indications for the use of aspirin in diabetic patients according to the guidelines were remarkable. Guidelines that minimize these differences are needed for clinicians, and compliance with these guidelines in clinical practice could reduce inappropriate aspirin use. [ABSTRACT FROM AUTHOR]

- Abstract
OBJECTIVE: The aim of the study was to investigate the existence of neuroendocrine cells and to compare the density of those in normal ovarian tissue, endometriotic and non-endometriotic benign ovarian cysts. PATIENTS AND METHODS: Twenty patients with the diagnosis of endometrioma and 30 control subjects consisting of ovarian serous cystadenoma (n=10), ovarian mucinous cystadenoma (n=10) and normal ovarian tissue (n=10) were included. The tissues were prepared and assessed according to staining density by using the H-score method. RESULTS: Tissues with mucinous cystadenoma were significantly more stained with PAS and VanGieson, when compared to women with endometrioma. Macrophage deposition was higher in cyst samples with endometrioma and in normal ovarian tissue when compared to serous cystadenoma and mucinous cystadenoma. Normal ovarian tissue was significantly more stained with PGP9.5, NSE and SYN when compared to endometrioma and non-endometriotic benign ovarian cyst. PGP9.5 staining was higher in normal ovarian tissue when compared with endometriotic lesions (p<.001). Endometrioma samples were significantly more stained with p53 when compared to non-endometriotic cysts and normal ovarian tissue. c-Kit staining was mild and not statistically significant among all groups. CONCLUSIONS: During endometrioma transformation, expression intensity of neuroendocrine markers decreases compared to normal ovarian tissue and other benign ovarian cysts. [ABSTRACT FROM AUTHOR]

- Abstract
OBJECTIVE: DNA repair genes may be related with the onset of primary ovarian failure (POF). The study was planned to investigate whether the polymorphisms in the DNA repair genes modulate the risk of POF. PATIENTS AND METHODS: This prospective study included 25 women diagnosed with POF and 25 healthy controls. The genotyping and allele of XRCC1 and XPD genes were determined by using Polymerase Chain Reaction and fluorescence melting curve analysis. RESULTS: The genotype and allele distribution of the Arg194Trp and Arg399Lys polymorphism of the XRCC1 gene did not differ statistically between those of the POF and control groups. The frequency of the C (Gln) allele was significantly lower in patients diagnosed with POF when compared to that in healthy controls [48% vs. 76%, p=0.040, OR: 3.43 (CI: 1.03-11.48)]. The Lys/Lys genotype for XPD-Lys751Gln polymorphism in patients diagnosed with POF was more common than in healthy controls (p=0.028, 52% vs. 24%). CONCLUSIONS: The genotype distribution and allele frequency of XPD-Lys751Gln, XRCC1-Arg-194Trp and XRCC1-Arg399 Gln did not regulate the risk of developing POF. Gln/Gln+Lys/Gln and XPD-Lys751Gln polymorphism may have a possible protective role against the development of POF. [ABSTRACT FROM AUTHOR]

- Abstract
Abstract: This observational cohort study investigated the potential of a novel sperm-washing medium (SWM) enriched with serotonin (5-HT), L-carnitine (L-C), and coenzyme Q10 (CoQ10) to enhance sperm motility and reduce DNA damage. It compared this innovative medium (5-HT/L-C/CoQ10 SWM) with two widely used commercial media (SWM 1 and SWM 2). Ninety-eight volunteers from an infertility clinic provided semen samples, which were divided into three aliquots for analysis in different SWMs: group 1, SWM was composed of hydroxyethyl piperazineethanesulfonic acid (HEPES), sodium bicarbonate, human serum albumin (HSA), taurine, and gentamicin sulfate (SWM 1); group 2, SWM was composed of HEPES, sodium bicarbonate, and HSA (SWM 2); and group 3, SWM was composed of HEPES-buffered human tubal fluid supplemented with 5-HT, L-C, and CoQ10 (5-HT/L-C/CoQ10 SWM). Sperm motility was categorized as progressive, nonprogressive, or immotile. Apoptosis, reactive oxygen species (ROS) production, and DNA fragmentation were also assessed. There were no significant differences in total or progressive sperm motility among the groups. Spermatozoa in group 3 exhibited reduced apoptosis, necrosis, and ROS levels and increased viability. No significant differences were observed in the DNA fragmentation index among groups. The 5-HT/L-C/CoQ10 SWM reduced sperm oxidative stress and apoptosis compared with those of the two commercially available SWMs, suggesting that 5-HT/L-C/CoQ10 SWM could be useful for enhancing in vitro fertilization success rates., (Copyright © 2024 Copyright: ©The Author(s)(2024).)

- Abstract
Purpose: With significant advancements in laparoscopic procedures and tools over the last decade, the partial nephrectomy (PN) surgical approach has gradually transformed from open to laparoscopic partial nephrectomy (LPN). Although numerous studies evaluating the postoperative complications of laparoscopic partial nephrectomy can be found in the literature, a scoring system that addresses both preoperative physical condition and intraoperative risk factors has not yet been established. The Estimation of Physiological Ability and Surgical Stress (E-PASS) score is a scoring system that considers both the patient's preoperative condition and intraoperative variables to predict the risk of postoperative complications in surgically treated patients. This study aimed to assess the applicability of the E-PASS scoring system for predicting postoperative complications following LPN., Methods: We analyzed data of 196 patients who underwent LPN between 2017 and 2024 by a single surgeon in this single-center retrospective study. Demographic data of the patients, parameters reflecting patients' preoperative physical condition, and intraoperative risk factors were recorded. Postoperative complications were classified using the Clavien-Dindo system. The E-PASS score and its sub-scores were calculated for each patient., Results: Various degrees of complications developed in 46 patients (23.5%). Patients who developed complications had significantly higher mean age, performance scores, tumor sizes, length of hospital stay, and E-PASS values. The cutoff value of the E-PASS Comprehensive Risk Score (CRS) for predicting the development of postoperative complications was determined to be - 0.1692 (AUC = 0.676; 95% CI 0.581-0.771; p < 0.001). According to the results of the multivariate analysis, the presence of E-PASS CRS > - 0.1692 (OR 4.872; 95% CI 2.384-9.957; p < 0.001) and tumor size (OR 1.021; 95% CI 1-1.041; p = 0.047) was identified as independent risk factors predicting postoperative complications. Patients with a CRS higher than the cutoff value had a 4.87 times higher rate of postoperative complications after LPN., Conclusion: The E-PASS scoring model successfully predicts postoperative complications in patients undergoing LPN by utilizing preoperative data on the patient's physical condition and surgical risk factors. The E-PASS score and its sub-scores can serve as objective criteria to determine the risk of postoperative complications both preoperatively and immediately postoperatively., (© 2024.

- Abstract
Objective: To determine whether the urinary excretion of podocyte degradation products varies according to PCOS phenotype and metabolic syndrome (MetS). Methods: The concentrations of podocalyxin (PDX) and nephrin, chronic markers of podocyte damage, and neutrophil gelatinase-associated lipocalin (NGAL), a marker of acute glomerular damage, were analyzed in the morning urine samples of 50 PCOS patients and 50 healthy controls matched by age and BMI. Albuminuria was assessed by calculating the urine albumin-creatinine ratio (uACR). Results: The PDX, nephrin and NGAL concentrations of PCOS participants were significantly higher than those of the control group. While PDX, nephrin and NGAL levels of classic phenotypes were similar, they were higher than ovulatory and non-hyperandrogenic phenotypes. Significant increases in urinary levels of each podocyte protein were detected in PCOS patients with MetS compared to patients without MetS. A positive significant correlation between podocyte proteins and BMI, systolic blood pressure, testosterone, glucose, HOMA-IR and uACR. After adjusting for age and BMI, podocyte proteins were an independent risk factor for microalbuminuria. The incidence of microalbuminuria in PCOS increased 6-fold compared to controls. The frequency of microalbuminuria was higher in classical phenotypes than in ovulatory phenotype. The frequency of microalbuminuria in PCOS patients with MetS was 6.5 times higher than in PCOS patients without MetS. Conclusions: In PCOS accompanied by hyperandrogenemia or metabolic syndrome, leakage of acute and chronic podocyte breakdown products into the urine becomes more pronounced.

- Abstract
Objectives: This study aimed to assess the effectiveness of deep convolutional neural network (CNN) algorithms for the detecting and segmentation of overhanging dental restorations in bitewing radiographs., Methods: A total of 1160 anonymized bitewing radiographs were used to progress the artificial intelligence (AI) system for the detection and segmentation of overhanging restorations. The data were then divided into three groups: 80% for training (930 images, 2399 labels), 10% for validation (115 images, 273 labels), and 10% for testing (115 images, 306 labels). A CNN model known as You Only Look Once (YOLOv5) was trained to detect overhanging restorations in bitewing radiographs. After utilizing the remaining 115 radiographs to evaluate the efficacy of the proposed CNN model, the accuracy, sensitivity, precision, F1 score, and area under the receiver operating characteristic curve (AUC) were computed., Results: The model demonstrated a precision of 90.9%, a sensitivity of 85.3%, and an F1 score of 88.0%. Furthermore, the model achieved an AUC of 0.859 on the receiver operating characteristic (ROC) curve. The mean average precision (mAP) at an intersection over a union (IoU) threshold of 0.5 was notably high at 0.87., Conclusions: The findings suggest that deep CNN algorithms are highly effective in the detection and diagnosis of overhanging dental restorations in bitewing radiographs. The high levels of precision, sensitivity, and F1 score, along with the significant AUC and mAP values, underscore the potential of these advanced deep learning techniques in revolutionizing dental diagnostic procedures., (© The Author(s) 2024.

- Abstract
Objective: The aim of this study is to determine if a deep learning (DL) model can predict the surgical difficulty for impacted maxillary third molar tooth using panoramic images before surgery., Materials and Methods: The dataset consists of 708 panoramic radiographs of the patients who applied to the Oral and Maxillofacial Surgery Clinic for various reasons. Each maxillary third molar difficulty was scored based on dept (V), angulation (H), relation with maxillary sinus (S), and relation with ramus (R) on panoramic images. The YoloV5x architecture was used to perform automatic segmentation and classification. To prevent re-testing of images, participate in the training, the data set was subdivided as: 80 % training, 10 % validation, and 10 % test group., Results: Impacted Upper Third Molar Segmentation model showed best success on sensitivity, precision and F1 score with 0,9705, 0,9428 and 0,9565, respectively. S-model had a lesser sensitivity, precision and F1 score than the other models with 0,8974, 0,6194, 0,7329, respectively., Conclusion: The results showed that the proposed DL model could be effective for predicting the surgical difficulty of an impacted maxillary third molar tooth using panoramic radiographs and this approach might help as a decision support mechanism for the clinicians in peri‑surgical period., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Masson SAS.

- Abstract
The purpose of this study was to assess the awareness and knowledge of professional team sport athletes about ACL injuries, injury prevention programs, and the return to sports after ACL injuries. A total of 419 athletes representing soccer, basketball, volleyball and handball sports were included in the study. We utilized a 15-item self-report survey to assess the awareness of athletes about ACL injury, ACL injury prevention program, and return to sport after ACL injuries. Male and soccer players participated in prevention programs more than female athletes ( p = 0.001). Participation in prevention programs was significantly higher in the ≥ 18 years old group than in the < 18 years old group ( p = 0.040). Participants who were informed about ACL injuries were 8.4 times more likely to participate in the ACL injuries prevention program than others (OR: 8.38, 95% CI: 3.823-18.376, p < 0.001). The majority of participants believed that return to sport after ACL injury takes 6 months and 81.4% of them thought that it is not possible to do sport without an ACL. This study revealed that the awareness and performance of ACL prevention training programs among professional team sport athletes were insufficient. The athletes' knowledge regarding return to sports after ACL injuries was also inadequate. Improving athletes' knowledge of ACL injuries may lead to increased participation in ACL injury prevention programs. Thus, the provision of tailored educational interventions to athletes could potentially enhance their awareness and understanding of ACL injuries, consequently contributing towards the prevention of such injuries.

- Abstract
Objective: Primary hypophysitis might be challenging to diagnose, and there is a lack of evidence regarding optimal treatment strategies due to rarity of the disease. We aim to investigate the clinical features and compare the outcomes of different management strategies of primary hypophysitis in a large group of patients recruited on a nationwide basis., Design: A retrospective observational study., Methods: The demographic, clinical, and radiologic features and follow-up data were collected in study protocol templates and analyzed., Results: One hundred and thirteen patients (78.8% female, median age: 36 years) were included. Lymphocytic (46.7%) and granulomatous hypophysitis (35.6%) were the prevailing subtypes out of 45 patients diagnosed after pathologic investigations. Headache (75.8%) was the most common symptom, and central hypogonadism (49.5%) was the most common hormone insufficiency. Of the patients, 52.2% were clinically observed without interventions, 18.6% were started on glucocorticoid therapy, and 29.2% underwent surgery at presentation. Headache, suprasellar extension, and chiasmal compression were more common among glucocorticoid-treated patients than who were observed. Cox regression analysis revealed higher hormonal and radiologic improvement rates in the glucocorticoid-treated group than observation group (hazard ratio, 4.60; 95% CI, 1.62-12.84 and HR, 3.1; 95% CI, 1.40-6.68, respectively). The main indication for surgery was the inability to exclude a pituitary adenoma in the presence of compression symptoms, with a recurrence rate of 9%., Conclusion: The rate of spontaneous improvement might justify observation in mild cases. Glucocorticoids proved superior to observation in terms of hormonal and radiologic improvements. Surgery may not be curative and might be considered in indeterminate, treatment-resistant, or severe cases., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2024.

After the mobile application was created, 10 children and their families were interviewed., Results: Nine of the families (90%) found the developed mobile application useful and easy to use. Families' suggestions to improve the mobile application were to make it more interesting for children and to enrich its content., Conclusion: In line with the feedback, the mobile application was updated and finalised. Preliminary results are promising that the developed mobile application can be used as an aid to treatment in children with urinary incontinence. With the mobile application developed, urotherapy training was not limited to the time they visited the hospital. This suggests that the mobile application can eliminate the problem of partial or omitted treatment. This research has shown that leveraging technology can be a good option to increase treatment success., Clinical Trial Number: NCT05815940., (© 2024 John Wiley & Sons Ltd.)

- Abstract
Purpose: This study aims to analyze the experience of a tertiary health center about the management of adnexal masses that have been diagnosed during pregnancy or detected accidentally during cesarean delivery., Methods: This is a retrospective review of 160 women who underwent concurrent surgery for adnexal mass during cesarean section, 24 women who delivered vaginally and subsequently had surgery due to the prenatal diagnosis of adnexal mass and 10 women who underwent surgery for adnexal mass during pregnancy. Corresponding to the delivery and surgery times, 200 women who had no diagnosis of pregnancy-associated adnexal mass served as controls., Results: The women in the control group and study groups had statistically similar gestational age at delivery, birth weight and preterm delivery (p > 0.05 for all). Miscarriage was significantly more frequent in women undergoing surgery for adnexal mass during pregnancy (p = 0.001). The women who had surgery for adnexal mass during pregnancy, at the time of cesarean section and following delivery were statistically similar with respect to surgery type and histopathological diagnosis (p > 0.05 for both). Malignancy was detected in none of the patients who underwent surgery for adnexal mass during pregnancy. Acute abdomen was the indication for the emergency surgery in six patients (3.5%) who had surgery for adnexal mass during pregnancy. Four patients (2.4%) had surgery for adnexal mass during pregnancy due to the high index of suspicion for malignancy., Conclusion: The risk of malignancy was relatively lower in this cohort of adnexal masses detected during pregnancy and cesarean delivery. Surgical management of adnexal masses should be postponed to postpartum period as such management leads to an increased risk of miscarriage. Unless there is a need for emergent surgery or cancer staging, vaginal delivery should be encouraged in women diagnosed with adnexal mass during pregnancy., (© 2024.

- Abstract
Objectives: The purpose of this study was to evaluate the effectiveness of dental caries segmentation on the panoramic radiographs taken from children in primary dentition, mixed dentition, and permanent dentition with Artificial Intelligence (AI) models developed using the deep learning method., Methods: This study used 6075 panoramic radiographs taken from children aged between 4 and 14 to develop the AI model. The radiographs included in the study were divided into three groups: primary dentition (n: 1857), mixed dentition (n: 1406), and permanent dentition (n: 2812). The U-Net model implemented with PyTorch library was used for the segmentation of caries lesions. A confusion matrix was used to evaluate model performance., Results: In the primary dentition group, the sensitivity, precision, and F1 scores calculated using the confusion matrix were found to be 0.8525, 0.9128, and 0.8816, respectively. In the mixed dentition group, the sensitivity, precision, and F1 scores calculated using the confusion matrix were found to be 0.7377, 0.9192, and 0.8185, respectively. In the permanent dentition group, the sensitivity, precision, and F1 scores calculated using the confusion matrix were found to be 0.8271, 0.9125, and 0.8677, respectively. In the total group including primary, mixed, and permanent dentition, the sensitivity, precision, and F1 scores calculated using the confusion matrix were 0.8269, 0.9123, and 0.8675, respectively., Conclusions: Deep learning-based AI models are promising tools for the detection and diagnosis of caries in panoramic radiographs taken from children with different dentition.

- Abstract
Background: Silent new cerebral ischemic lesions (sNCIL) are a common complication of carotid artery stenting (CAS) that can lead to an increase in morbidity and mortality. We aimed to evaluate the impact of hematological parameters on sNCIL in patients undergoing CAS., Methods: We retrospectively evaluated 103 patients who underwent CAS, with a mean age of 70.5 ± 6.7 years, and 31 (20.1 %) of whom were female. Stents were placed for internal carotid artery revascularization. The presence of new hyperintense lesions on diffusion-weighted imaging (DWI) without neurological symptoms was considered as sNCIL in cases without apparent neurological findings. Patients were categorized into two groups based on DWI results: positive (29) and negative (74)., Results: In the study population, sNCIL was observed in 29 patients (28.2 %). The DWI-positive group exhibited significantly higher Plateletcrit (PCT) levels, advanced age, and a lack of embolic protection device usage compared to the DWI-negative group. The Receiver Operating Characteristic (ROC) analysis identified a PCT value of 0.26 as the optimal threshold, detecting the development of sNCIL with a sensitivity of 75.9 % and specificity of 59.1 % (AUC: 0.700; 95 % CI: 0.594-0.806, p = 0.002)., Conclusion: To be determined by a simple blood parameter, PCT can predict the risk of sNCIL before CAS and holds clinical value in the treatment of patients with carotid artery stenosis., Competing Interests: Declaration of competing interest The authors did not receive any financial support for research , authorship, and/or publication of this manuscript .

- Abstract
Objectives: The study aims to develop an artificial intelligence (AI) model based on nnU-Net v2 for automatic maxillary sinus (MS) segmentation in cone beam computed tomography (CBCT) volumes and to evaluate the performance of this model., Methods: In 101 CBCT scans, MS were annotated using the CranioCatch labelling software (Eskisehir, Turkey) The dataset was divided into 3 parts: 80 CBCT scans for training the model, 11 CBCT scans for model validation, and 10 CBCT scans for testing the model. The model training was conducted using the nnU-Net v2 deep learning model with a learning rate of 0.00001 for 1000 epochs. The performance of the model to automatically segment the MS on CBCT scans was assessed by several parameters, including F1-score, accuracy, sensitivity, precision, area under curve (AUC), Dice coefficient (DC), 95% Hausdorff distance (95% HD), and Intersection over Union (IoU) values., Results: F1-score, accuracy, sensitivity, precision values were found to be 0.96, 0.99, 0.96, 0.96, respectively for the successful segmentation of maxillary sinus in CBCT images. AUC, DC, 95% HD, IoU values were 0.97, 0.96, 1.19, 0.93, respectively., Conclusions: Models based on nnU-Net v2 demonstrate the ability to segment the MS autonomously and accurately in CBCT images., (© The Author(s) 2024.

- Abstract
Objective: Infantile myofibromatosis is a rare entity of childhood characterized by benign myofibroblastic tumors in the soft tissues, the bones, and occasionally the viscera. Solitary skeletal lesions are relatively uncommon. Calvarial involvement should be distinguished from more aggressive tumors for appropriate treatment., Methods: We reviewed solitary infantile myofibroma of the calvarium and discussed the relevant computed tomography and magnetic resonance imaging findings along with differential diagnosis. A case study of the frontal bone in a 5-month-old girl was also presented., Results: Fourteen cases were reviewed, including the current case. Of the 13 cases with known sex, eight were male and five female. The mean age was 3.03 with an age range of 0.41-9 years. Nine of the 14 tumors were in the frontal bone. The lesions were intradiploic with tabula interna and/or externa of the calvaria involvement. The mean largest diameter was 22.3 mm. Upon computed tomography, all the lesions were expansile and lytic, and hypoattenuated, isoattenuated or occasionally hyperatenuated. Calcification was not seen. On magnetic resonance imaging, most neoplasms were hypointense on T1-weighted and T2-weighted images. Neoplasms showed hypointense signal on diffusion-weighted imaging and hyperintense on apparent diffusion coefficient, without restricted diffusion in three cases. All lesions were intensely enhanced after gadolinium administration. Treatment was total surgical resection and recurrence was not observed during follow-up., Conclusions: Infantile myofibromas are rare, typically intradiploic expansile lytic lesions with tabula interna and/or externa involvement. Distinctive imaging features include the presence of hipointense signals on T2-weighted magnetic resonance images without restricted diffusion on diffusion-weighted imaging. A slow-growing, firm, painless, and nontender mass with supportive imaging findings should raise suspicion of the disease., (© 2024.

- Abstract
Introduction: Hyponatremia is the most common electrolyte disorder often present in peritoneal dialysis (PD) patients. The aim of this retrospective study was to investigate the effect of hyponatremia on mortality in patients undergoing PD., Methods: The health records of adult individuals with an inserted PD catheter identified via the centralized national e-health database were used., Results: The mean age of the 846 patients included in the study was 52.48 years (±14.6). The mean sodium level was 136.51 mEq/L. Sodium levels <137 mEq/L were associated with higher death risk independent of comorbidities. There was a 0.821 times less reduction in mortality for each mEq /L increase in serum sodium., Conclusion: Our study provides evidence that monitoring and adjusting serum sodium levels is crucial in managing PD patients with hyponatremia, as low serum sodium level was found to be a significant and independent predictor of mortality., (© 2023 International Society for Apheresis and Japanese Society for Apheresis.)

- Abstract
Objective: This study aimed to develop machine learning (ML) algorithms for the differential diagnosis of adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome (CS) based on biochemical and radiological features., Methods: Logistic regression algorithms were used for ML, and the area under the receiver operating characteristics curve (AUROC) was used to measure performance. We used Shapley Contributed Comments (SHAP) values, which help explain the results of the ML models to identify the meaning of each feature and facilitate interpretation., Results: A total of 106 patients, 80 with Cushing's disease (CD) and 26 with ectopic ACTH syndrome (EAS), were enrolled in the study. The ML task was created to classify patients with ACTH-dependent CS into CD and EAS. The average AUROC value obtained in the cross-validation of the logistic regression model created for the classification task was 0.850. The diagnostic accuracy of the algorithm was 86%. The SHAP values indicated that the most important determinants for the model were the 2-day 2-mg dexamethasone suppression test, the > 50% suppression in the 8-mg high-dose dexamethasone test, late-night salivary cortisol, and the diameter of the pituitary adenoma. We have also made our algorithm available to all clinicians via a user-friendly interface., Conclusion: ML algorithms have the potential to serve as an alternative decision support tool to invasive procedures in the differential diagnosis of ACTH-dependent CS., (© The Author(s) 2024.

- Abstract
Background: This study aimed to evaluate the efficacy and safety of Pro-Glide, a suture-mediated vascular closure device, regarding technical success and complications in patients who had undergone aortic intervention and had previous groin intervention (PGI)., Methods: One hundred and thirty-five patients who underwent percutaneous thoracic endovascular aortic repair via the femoral artery and were closed with the Pro-Glide device were analyzed retrospectively. PGI was defined as a history of open surgical access to the femoral artery or wide sheath (>18 F) placement due to endovascular or valvular intervention. The patients were divided into two groups 38 cases with PGI and 97 cases without PGI., Results: The overall success rate of closure of the femoral artery with Pro-Glide was not statistically significant between the two groups (93.8% vs 92.1%, p = .711). Sheath sizes were compared between the groups and PGI (+) group had significantly higher sheath sizes compared to PGI (-) group (24.3 ± 1.1 F vs 23.8 ± 1.0 F, p = .011). Three patients in the PGI (+) group and six patients in the PGI (-) group experienced technical failure of the percutaneous femoral approach. Femoral complications were seen after the procedures in four patients in the PGI (+) group and four in the PGI (-) group. The PGI (+) group had a higher complication rate when compared to the PGI (-) group; however, this was not statistically significant ( p = .181)., Conclusion: The present study was conducted on a significantly larger sample compared to previous studies and the findings suggest that the Pro-Glide vascular closure device is a safe option for patients with a history of PGI and may not be considered as a contraindication., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Background: A fine-tuned pro-inflammatory and anti-inflammatory balance in the follicular unit is essential for cumulus expansion and successful ovulation. While the long pentraxin 3 (PTX3) gene is required for the expansion of cumulus cells (CCs), ovulation, resumption of meiosis and fertilization, the vitamin D receptor gene (VDR-X2) is required for intra-follicle redox balance. This study was planned to determine the expression pattern of VDR-X2 and PTX3 mRNA in CCs isolated from germinal vesicle (GV), metaphase I (MI), and metaphase II (MII) oocytes of PCOS patients with ovulatory dysfunction., Methods: The relative expression of CC-PTX3 and CC-VDR-X2 mRNA were evaluated using qRT-PCR in a total of 79 CC samples collected from individual cumulus-oocyte complex of 40 infertile patients (20 PCOS and 20 non-PCOS normal responders) who underwent ovarian stimulation with the GnRH antagonist protocol., Results: Relative PTX3 mRNA expressions of CCMI-control and CCMII-control showed 3- and 9-fold significant upregulation compared to CCGV-control, respectively. The relative PTX3 mRNA expression of CCMII-control increased approximately three fold compared to CCMI-control. Compared to CCGV-pcos, a 3-fold increase was noted in the relative PTX3 mRNA expression of CCMI-pcos and an approximately 4-fold increase in the PTX3 mRNA expression of CCMII-pcos. Relative PTX3 mRNA expression values of CCMII-pcos and CCMI-pcos were similar. A 6-fold upregulation of relative PTX3 mRNA and a 4-fold upregulation of VDR-X2 mRNA were detected in CCMII-control compared to CCMII-pcos. CC-VDR-X2 expression patterns of the PCOS and control groups overlapped with the CC-PTX3 pattern. Fertilization rates of the PCOS group exhibiting failed transcript expression were similar to normal responders., Conclusion: The fact that relative CC-PTX3 and CC-VDR mRNA expression does not increase during the transition from MI to MII stage in PCOS as in normal responders suggests that PTX3 and VDR expression may be defective in cumulus cells of PCOS patients with ovulatory dysfunction., (© 2023.

- Abstract
Food security is an important factor in ensuring a healthy diet. However, it has been reported that women are more vulnerable to food insecurity than men in many countries. In addition, there is little evidence that Mediterranean diet (MD) adherence is associated with a lower risk of food insecurity. Therefore, this study aimed to evaluate food insecurity and associated factors in women of childbearing age. In addition, women's adherence to MD and its relationship with food insecurity were evaluated. This descriptive and cross-sectional study was conducted with 2675 adult women aged 18-49. The demographic characteristics, anthropometric measurements, nutritional habits, compliance with the MD, and the level of food insecurity were evaluated using the structured, self-administered, web-based questionnaire form. The mean age of the individuals was 29.5 ± 10.35 years. 21.6% of individuals had food insecurity, and 5.2% had severe food insecurity. 36.4% of the individuals adhere to the MD. There was a statistically significant difference between the individuals with and without food security regarding age, marital status, and income status ( p < .05). However, there was no statistically significant difference in terms of the Mediterranean diet adherence score (MEDAS) and MEDAS classification between individuals with and without food security ( p > .05). It was determined that age, marital status, and income status affected food insecurity ( R
2 = 0.374; p < .001). Also, it was determined that age, number of main meals and snacks, and income status affected adherence to MD ( R2 = 0.286; p < .001). In conclusion, considering the fragility of women in food insecurity, more comprehensive studies should be conducted in this area to better define the factors associated with food insecurity in women and inform policymakers. In addition, the results of this study can shed light on comprehensive intervention studies in this area., Competing Interests: The authors declare that there are no conflicts of interest., (© 2023 The Authors.

- Abstract
Background: Peripheral arterial disease is a common disease all over the world. Medical treatment, percutaneous invasive treatment, and operation are the considerable options. Percutaneous treatment is a valid option with a higher patency rate. Systemic immune-inflammatory index (SII) is a formula which is calculated as neutrophil count to platelet count divided into lymphocyte count. This formula demonstrates the active inflammatory state. In our study, we aimed to demonstrate the relationship with SII and the mortality, major cardiovascular events, and success rates of percutaneous treatment of iliac artery disease., Methods: A total of 600 patients underwent percutaneous intervention due to iliac artery disease were enrolled. The primary end point was mortality and the secondary end points were in-hospital thrombosis, restenosis, residual stenosis, and postintervention complications. The best cut-off value of SII to predict mortality was determined and the patients were divided into 2 groups, as those with higher SII values (1,073.782 <) and as those with lower SII values (1,073.782 >). Each group was evaluated in terms of clinical, laboratory, and technical aspects., Results: After exclusion criteria were applied, 417 patients were enrolled into the study. Patients with high SII values had higher rates of in-hospital thrombosis [0 (0%); 3 (2.2%), P = 0.037] and mortality [38 (13.7%); 46 (33.1%), P < 0.001]. In multivariate logistic regression analysis, chronic kidney disease [odds ratio: 4.104, 95 0.5 confidence interval: 2.250-7.487, P < 0.001] and SII [odds ratio: 3.346, 95 0.5 confidence interval: 1.982-5.649, P < 0.001] were found to be independent risk factors for mortality., Conclusions: SII is a relatively new, simple, and effective mortality risk predictor in patients with iliac artery disease who underwent percutaneous intervention. To the best of our knowledge, our study is the first study which uses SII to predict mortality in such patient group., (Copyright © 2023 Elsevier Inc. All rights reserved.)

- Abstract
Purpose: To evaluate oral health-related quality of life (OHRQoL) in patients with temporomandibular disorders (TMDs) involving masticatory muscle pain, disc displacement with reduction, or both and to determine the associations of these disorders with anxiety., Materials and Methods: This study consisted of 150 patients with TMDs and 50 healthy controls. Patients were diagnosed according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) Axis I and then divided into three diagnostic groups: masticatory muscle pain (group MP), disc displacement with reduction (group DD), or both (group MPDD). The participants completed the Oral Health Impact Profile-14 (OHIP-14) and Generalized Anxiety Disorder-7 (GAD-7) questionnaires for assessment of OHRQoL and anxiety, respectively. Statistical analyses were performed using Kruskal-Wallis test and Mann-Whitney U post hoc paired-comparison tests., Results: A total of 121 of the patients (60.25%) were female and 79 (39.75%) were male, ranging from ages 18 to 68 years (mean age: 37.32 ± 13.62). Gender distribution, mean age, educational status, and occupational status were similar among groups. The OHIP-14 global and domain scores and distribution of GAD-7 levels were significantly different among groups ( P < .001). For psychologic discomfort and disability domains, group MPDD statistically scored the highest, followed by group MP, group DD, and then the control group ( P < .05). According to correlation analyses, there were positive correlations between the GAD-7 and all OHIP-14 scores (r = 0.438, P < .001) within group MPDD., Conclusion: OHRQoL is negatively affected by TMDs and worsens as the severity of anxiety increases. Therefore, physical conditions and anxiety levels in TMD patients should be simultaneously considered for treatment and maintenance. Int J Prosthodont 2023;36:148-154. doi: 10.11607/ijp.7587.

- Abstract
Background: Omphalocele is associated with many aneuploidies, deletions and congenital anomalies. This study evaluates pregnancies diagnosed with omphalocele and its relevance to concomitant genetic disorders., Methods: The data of patients with the intrauterine diagnosis of omphalocele who had invasive diagnostic testing performed between January 2017 and January 2020 were evaluated retrospectively. The traditional karyotype analysis was performed to prenatal diagnosis for all fetuses. During the study period, all patients were scanned via ultrasonography by an experienced perinatologist, prenatally., Results: We evaluated 22 cases of omphalocele whose genetic testing results were available. The mean maternal age was 25 (18-41) years. The median gestational week at diagnosis was 13 (11-22). Invasive genetic testing revealed aneuploidy in 7 patients (31.8%), 2 with trisomy 13 (9.1%), and 5 with trisomy 18 (22.8%). There were 5 fetuses (22.7%) that had extracorporeal liver: 1 had trisomy 18 (20%), 1 had trisomy 13 (20%), and the other 3 fetuses had a normal karyotype (60%). Further, 14 (63.6%) pregnancies were terminated: 4 had trisomy 18 (28.6%), 1 had trisomy 13 (7.1%), and 9 of the terminated pregnancies (64.3%) had additional congenital anomalies. There were 4 infants who died (50%) born from 8 patients who decided to continue with their pregnancy. The omphalocele sac of 1 infant spontaneously regressed in the ensuing weeks of pregnancy who is now 1 year old., Conclusions: The chromosomal abnormalities presented in up to 31.8% of cases diagnosed with omphalocele. Moreover, for cases with normal genetic testing results, the propensity for additional structural defects was high and the prognosis remains poor. Counseling parents to consider their option of terminating the pregnancy is appropriate.

- Abstract
Background: The prognostic value of C-reactive protein/albumin ratio (CAR) is of import in cardiovascular diseases. Our aim was to evaluate the impact of the CAR in patients with asymptomatic abdominal aortic aneurysm (AAA) undergoing endovascular aneurysm repair (EVAR)., Material and Method: We retrospectively evaluated 127 consecutive patients who underwent technically successful elective EVAR procedure between December 2014 and September 2020. The optimal CAR cut-off value was determined by using receiver operating characteristic (ROC) curve analysis. Based on the cut-off value, we investigated the association of CAR with long-term all-cause mortality., Results: 32 (25.1%) of the patients experienced all-cause mortality during a mean 32.7 ± 21.7 months' follow-up. In the group with mortality, CAR was significantly higher than in the survivor group (4.63 (2.60-11.88) versus 1.63 (0.72-3.24), p < 0.001). Kaplan-Meier curves showed a higher incidence of all-cause mortality in patients with high CAR compared to patients with low CAR (log-rank test, p < 0.001). Multivariable Cox regression analysis revealed that glucose ≥ 110 mg/dL (HR: 2.740; 95% CI: 1.354-5.542; p = 0.005), creatinine ≥ 0.99 mg/dL (HR: 2.957, 95% CI: 1.282-6.819, p = 0.011) and CAR > 2.05 (HR: 8.190, 95% CI: 1.899-35.320, p = 0.005) were the independent predictors of mortality., Conclusion: CAR was associated with a significant increase in postoperative long-term mortality in patients who underwent EVAR. Preoperatively calculated CAR can be used as an important prognostic factor.

- Abstract
Background: Inaccurate test results may be a reason why vitamin D deficiency is seen as a common problem worldwide. Interferences from the sample matrix during testing are the most important factors in measurement errors. In this study, the relationship between triglycerides and total cholesterol levels and vitamin D levels in Turkey was investigated., Methods: The 25-hydroxyvitamin D test results and lipid test results studied in Turkey in 2021 were compared. Data were obtained from the Ministry of Health National Health Database. Simultaneously, 25-hydroxyvitamin D, triglyceride, and total cholesterol levels were studied, and 1,135,644 test results were taken as the basis., Results: In the group of patients with total cholesterol levels between 0-10.33 mmol/L, the proportion of patients below 20 mg/L ranged from 56.8% to 61.8%. In the patient group with cholesterol between 10.36-259 mmol/L, the rate of patients with less than 20 mg/L was between 70.8-100%, while the rate of patients with cholesterol above 100 mg/L was 0%. The mean 25-hydroxyvitamin D level was 20.1 mg/L in the patient group with a total cholesterol level between 0-10.33 mmol/L, and 16 mg/L in the patient group with a cholesterol level above 10.36 mmol/L. The mean 25-hydroxyvitamin D level was 20.11 mg/L in the patient group with triglycerides 0-10.16 mmol/L, and the 25-hydroxyvitamin D level was 12.28 mg/L in the patient group with triglycerides 10.17-113 mmol/L. The proportion of patients with vitamin D levels above 100 mg/L was found to be 0% in the group of patients with triglycerides above 10.17-113 mmol/L., Conclusions: According to this study, there is a risk of toxicity when administering vitamin D therapy in patients with high cholesterol and triglycerides levels. This study is the first of this size in the literature. High triglycerides and cholesterol levels can cause inaccurate measurement of vitamin D levels, so care should be taken when evaluating these tests., Competing Interests: All the authors declare that they have no conflictof interest in this work.Conflict of Interest: The authors stated that they have no conflicts of interest regarding the publication of this article., (2023 Murat Çağlayan, Ataman Gonel, Tugba Songul Tat, Osman Celik, Fidanci Ali Aykut, Ayvali Mustafa Okan, Ulgu Mustafa Mahir, Naim Ata, Suayip Birinci, published by CEON/CEES.)

- Abstract
Objective: To compare functional outcome of microscopic and endoscopic approach regarding type of ossiculoplasty., Methods: In this retrospective study, cases who had undergone type-II and type-III tympanoplasty between February 2007 to September 2019 were divided into two groups according to the type of approach as microscopic and endoscopic. In cases with type-II reconstruction; Partial Ossicular chain Replacement Prosthesis (PORP), incus interposition and bone cement were used in order of frequency. Whereas in cases with type-III reconstruction, only Total Ossicular chain Replacement Prosthesis (TORP) was used. The average Air Bone Gap (ABG) was determined pre- and post-operatively for the calculation of Air Conductance Gain (ACG). The ACG, pre- and post-operative ABG values of each group were compared with regard to the type of ossiculoplasty., Results: A total of 79 cases consisting of 32 females and 47 males who had undergone type-II and type-III tympanoplasty were enrolled. No statistically significant difference between microscopic and endoscopic approach was found in terms of ACG (p = 0.42), pre-(p = 0.23) and postoperative ABG (p = 0.99). We did not find any significant difference in terms of ACG, pre- and postoperative ABG between two approaches for type-II and type-III reconstructions (p > 0.05)., Conclusions: According to the current study, endoscopic approach in type-II and type-III reconstruction is at least reliable as microscopic approach regarding functional outcome. Since both techniques have similar functional results, other factors (anatomic characteristics, habitude of the surgeon and duration of the surgery) should be considered when choosing the technique., Level of Evidence: In the current paper we present a retrospective comparative study of two different approaches of a particular type of otologic surgery. Level of evidence corresponds to level III., (Copyright © 2022 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial. Published by Elsevier España, S.L.U. All rights reserved.)

- Abstract
Background: Although it has been reported that the intermittent fasting (IF) diet has positive effects on heart health and improvement in blood pressure, it has not been sufficiently clarified how it could have these positive effects yet., Objective: We aimed to evaluate the effects of IF on the autonomic nervous system (ANS) and renin-angiotensin system (RAS), which are closely related to blood pressure., Methods: Seventy-two hypertensive patients were included in the study, and the data of 58 patients were used. All the participants fasted for about 15-16 hours for 30 days. Participants were evaluated with 24-hour ambulatory blood pressure monitoring and Holter electrocardiography before and after IF; also, 5 ml venous blood samples were taken for assessment of Serum angiotensin I (Ang-I) and angiotensin II (Ang-II) levels and angiotensin-converting enzyme (ACE) activity. For data analysis, the p-value <0.05 was accepted as significant., Results: Compared to pre-IF, a significant decrease was observed in the patients' blood pressures in post-IF. An increase in high-frequency (HF) power and the mean root square of the sum of squares of differences between adjacent NN intervals (RMSSD) were observed after the IF protocol (p=0.039, p=0.043). Ang-II and ACE activity were lower in patients after IF (p=0.034, p=0.004), and decreasing Ang-II levels were determined as predictive factors for improvement of the blood pressure, like the increase in HF power and RMSSD., Conclusion: The present findings of our study demonstrated an improvement in blood pressure and the relationship of blood pressure with positive outcomes, including HRV, ACE activity, and Ang-II levels after the IF protocol.

- Abstract
Background: Homeobox genes A10 (HOXA10) and A11 (HOXA11), members of the abdominal B gene family, are responsible for embryonic survival and implantation. This study was planned to investigate whether endometrial injury alters the expression of both transcripts in women with implantation failure., Methods: A total of 54 women with implantation failure were divided into two equal groups as experimental (scratching) and sham (no scratching). Participants in the scratching group were exposed to endometrial injury in the mid-luteal phase, and those in the sham group were exposed to endometrial flushing. The scratching group, but not the sham group, underwent prior endometrial sampling. A second endometrial sampling was performed on the scratching group in the mid-luteal phase of the following cycle. The mRNA and protein levels of the HOXA10 and 11 transcripts were determined in endometrial samples collected before and after injury/flushing. Participants in each group underwent IVF/ET in the cycle after the second endometrial sampling., Results: Endometrial injury caused a 60.1-fold ( p < 0.01) increase in HOXA10 mRNA and a 9.0-fold increase in HOXA11 mRNA ( p < 0.02). Injury resulted in a significant increase in both HOXA10 ( p < 0.001) and HOXA11 protein expression ( p < 0.003). There was no significant change in HOXA10 and 11 mRNA expressions after flushing. Clinical pregnancy, live birth, and miscarriage rates of the both groups were similar., Conclusions: Endometrial injury increases homeobox transcript expression at both mRNA and protein levels.

- Abstract
Objectives: Treatment of abdominal aortic aneurysms (AAA) with endovascular aortic repair (EVAR) has become quite common in recent years. This method, which has many advantages compared to the open surgical procedure, also has some complications. One of these complications is acute kidney injury (AKI). ACEF (age, creatinine, and ejection fraction) score, which is gaining popularity, can be an easy-to-use and cost-effective method in detecting this condition that causes increased morbidity and mortality. We aimed to evaluate whether this ACEF score may predict a development of AKI in patients who underwent EVAR., Methods: A total of 133 consecutive patients with AAA who underwent EVAR were analyzed. The primary endpoint of the study was the development of AKI. The best cut-off value for the ACEF score to predict the development of AKI was calculated and according to this value, the patients were divided into two groups as those with high ACEF scores and those with low ACEF scores. ACEF score was calculated by the formula of age/EF + 1 (if baseline creatinine > 2 mg/dL)., Results: After the exclusion criteria, a total of 118 patients were included in the study, and 20 (16.9%) of them developed AKI after EVAR. In the ROC curve analysis, a cut-off value of 1.34 was found for the ACEF score, and scores above this value were found to be independent predictors of AKI development after EVAR. In addition to the ACEF score, the contrast media volume was also found to be an independent predictor of the development of AKI., Conclusion: In conclusion, ACEF is a simple and effective scoring system in patients undergoing EVAR. To the best our knowledge, our study is the first study which applies ACEF score to predict AKI in EVAR patients.

- Abstract
Introduction: The effect of vitamin D status on steatosis has not been fully elucidated. In this study, we planned to investigate this interaction using a large-scale population-based cohort., Material and Methods: Patients diagnosed with simple steatosis (K76.0) and non-alcoholic steatohepatitis (NASH) (K75.8) by using the International Classification of Diseases 10th Revision (ICD-10) coding system, and who had 25-hydroxyvitamin D (25OHD) measurements at the diagnosis, were included in the study. Control group comprised subjects without liver diseases. Age, gender, alanine aminotransferase (ALT) and 25OHD levels, and the date of the measurements were recorded., Results: We compared ALT and 25OHD measurements between the patient and control groups, and between the simple steatosis and NASH subgroups. 25OHD levels were lower and ALT levels were higher in the patient group (p < 0.001, effect size = 0.028, and p < 0.001, effect size = 0.442, respectively). Logistic regression analysis showed that when 25OHD levels decrease by 1 ng/dL, it increases the risk of being in the patient group by 3.7%., Conclusion: Our results suggest that vitamin D status may be related to the development of non-alcoholic fatty liver disease (NAFLD). Although this relationship is weak, it may be important in the pathogenesis of steatosis.

- Abstract
To which extent the pre-existing hypothyroidism or hyperthyroidism has an impact on coronavirus infection 2019 (COVID-19) outcomes remains unclear. The objective of this study was to evaluate COVID-19 morbidity and mortality in patients with pre-existing thyroid dysfunction. A retrospective cohort of patients with a polymerase chain reaction (PCR)-confirmed COVID-19 infection (n=14 966) from March 11 to May 30, 2020, was established using the database of the Turkish Ministry of Health. We compared the morbidity and mortality rates of COVID-19 patients with pre-existing hypothyroidism (n=8813) and hyperthyroidism (n=1822) to those patients with normal thyroid function (n=4331). Univariate and multivariate regression analyses were performed to identify the factors associated with mortality. Mortality rates were higher in patients with hyperthyroidism (7.7%) and hypothyroidism (4.4%) than those with normal thyroid function (3.4%) (p<0.001 and p=0.008, respectively). Pre-existing hyperthyroidism was significantly associated with an increased risk of mortality (OR 1.54; 95% CI, 1.02-2.33; p=0.042) along with advanced age, male gender, lymphopenia and chronic kidney disease (p<0.001 for all). Although a potential trend was noted, the association between pre-existing hypothyroidism and mortality was not significant (OR 1.36; 95% CI, 0.99-1.86; p=0.055). In conclusion, this study showed an association between pre-existing hyperthyroidism with higher COVID-19 mortality. A potential trend towards increased mortality was also observed for hypothyroidism. The risk was more pronounced in patients with hyperthyroidism., Competing Interests: The authors declare that they have no conflict of interest., (Thieme. All rights reserved.)

- Abstract
Background: Transcatheter aortic valve implantation (TAVI) is a less invasive and safe therapeutic alternative in patients who are at very high surgical risk or in whom there are contraindications to open surgery. On the other hand, allocating transcatheter therapy to the adequate candidates and identifying a reliable and validated risk stratification tool for mortality prediction is still lacking. The C-reactive (CRP) to albumin ratio (CAR) is a novel inflammation-based prognostic tool and it is strongly associated with inflammation severity and mortality. In this study, we aimed to elucidate the predictive significance of CAR for mortality in patients who underwent TAVI., Methods: The records of 321 consecutive patients who underwent TAVI due to symptomatic aortic stenosis between 1 January 2015 and 31 December 2020 were analysed. Patients were divided into two groups based on the CAR values. For each group, all-cause, cardiovascular, and non-cardiovascular mortality occurring >72 h after the index procedure and at maximum follow-up was documented., Results: The mean follow-up time was 40 (22-63) months. A total of 180 (56.1%) patients died during long-term follow-up. According to our study, median CAR values were significantly higher among patients who died during follow-ups compared to survivors [1.13 (0.69-2.21) vs 3.56 (1.53-10.00), p < 0.001]., Conclusion: Our data showed that CAR is an independent predictor of long-term mortality in patients undergoing TAVI due to symptomatic aortic stenosis.
