Background and Objectives: The aim of this study is to evaluate the relationship between serum estradiol (E2) levels measured on the day of antagonist administration and live birth rates (LBRs) in women undergoing IVF-ET with an antagonist protocol. Materials and Methods: Data from women who underwent IVF-ET with an antagonist protocol between 2011 and 2023 were retrospectively analyzed. Patients were divided into five groups on the basis of serum E2 levels measured on the day of antagonist administration (Group I: E2 < 400 pg/mL, Group II: 400 ≤ E2 < 650 pg/mL, Group III: 650 ≤ E2 < 800 pg/mL, Group IV:800 ≤ E2 < 1000 pg/mL, and Group V: E2 ≥ 1000 pg/mL). The independent effect of serum E2 levels on live birth was analyzed via an adjusted regression model. Results: A total of 1613 patients were included in the study. The overall LBR was 32.1%. The LBRs for Groups I, II, III, IV, and V were 28.9%, 37.8%, 26.4%, 32.2%, and 34.1%, respectively (p = 0.017). In the adjusted regression model, serum E2 levels measured on the day of antagonist administration < 400 pg/mL (OR: 0.752, 95% CI: 0.580-0.999, p = 0.048) and 650 ≤ E2 < 800 pg/mL (OR: 0.595, 95% CI: 0.388-0.911, p = 0.011) were identified as factors that reduce the likelihood of a live birth, adjusting for age, infertility duration, body mass index (BMI), cycle number, quality of embryo, and number of embryos transferred. Conclusions: The serum E2 level associated with the highest LBR in women undergoing IVF-ET with an antagonist protocol was found to be in the range of 400-650. Serum E2 levels < 400 pg/mL or in the range of 650-800 pg/mL were statistically significantly associated with a reduced LBR.

Background and Objectives: The Analgesia Nociception Index (ANI), a surrogate marker derived from heart rate variability (HRV) analysis, has been validated for assessing the balance between antinociception and nociception during propofol anesthesia. The ANI continuously monitors this balance, with values above 50 indicating optimal analgesia. By adjusting analgesic administration based on ANI values, anesthesiologists can provide more personalized intraoperative pain control. Remimazolam, a novel benzodiazepine anesthetic lacking intrinsic analgesic properties, exhibits distinct HRV patterns compared to propofol. Considering these differences, the validity of the ANI during remimazolam anesthesia remains uncertain. We evaluated the validity of the ANI by assessing its ability to detect nociceptive stimuli during remimazolam anesthesia. Materials and Methods: In total, 28 patients were administered general anesthesia using remimazolam and remifentanil. We evaluated changes in the ANI before and after tetanic stimulation. In addition, we investigated the association between hemodynamic responses during surgical incisions and changes in the ANI. Results: Tetanic stimulation resulted in a significant (p < 0.001) reduction in the ANI, from 62.0 (interquartile range [IQR] 50.5-76.0) to 44.0 (IQR 37.0-55.5). Of the 13 patients who experienced hemodynamic responses during surgical incision, the ANI significantly decreased from 63.2 ± 13.6 to 36.9 ± 13.8 following noxious surgical stimulation (p < 0.001). Conclusions: The ANI reflects the dynamic equilibrium between antinociception and nociception during remimazolam-based general anesthesia.

Background and Objectives: Prosthesis-patient mismatch (PPM) after surgical aortic valve replacement (SAVR) is associated with worse clinical outcomes and worse valve durability. The aim of this retrospective single-center study was to evaluate the consistency between predicted PPM (PPMp) and measured PPM (PPMm) after SAVR with three different bioprostheses. Materials and Methods: We analyzed data of all consecutive patients who underwent surgical aortic valve replacement with Magna Ease, Intuity, and Inspiris Resilia bioprostheses (Edwards Lifesciences, Irvine, CA, USA) at our institution. PPM was defined if EOAi ≤ 0.85 cm²/m². PPMm was determined by institutional echo lab-measured EOAi on discharge-day echocardiogram. PPMp was assessed using reference values for each valve model and size indexed to BSA based on height, weight, prosthesis type, and size. For the overall population and for the three valve types we evaluated the sensitivity, specificity, positive predicted value, negative predicted value, and accuracy of PPMp. Furthermore, the consistency between PPMm and PPMp were evaluated according to prosthesis type, size, stent internal diameter (ID), and true ID. Results: A total of 1323 patients underwent SAVR; complete hemodynamic data were available for 872 patients, who represent the population of our study. Magna Ease, Intuity, and Inspiris Resilia were implanted in 446 (51.1%), 341 (39.1%), and 85 (9.7%) patients, respectively. In 635 out of 872 cases (72.8%), PPMp was consistent with PPMm (Magna Ease: 321/446, 72%; Inspiris Resilia: 58/85, 68.2%; Intuity: 256/341, 75%). Overall, the sensitivity, specificity, positive predicted value, negative predicted value, and accuracy of PPMp were 0.26, 0.83, 0.24, 0.84, and 0.73, respectively (Magna Ease: 0.21, 0.82, 0.3, 0.8, and 0.72; Inspiris Resilia: 0.11, 0.82, 0.14, 0.79, and 0.68; Intuity: 0.45, 0.78, 0.19, 0.93, and 0.75). Conclusions: The consistency between PPMp and PPMm was suboptimal. We did not observe differences between PPMp and PPMm among different valve types. Discordance between PPMp and PPMm was more evident in smaller valve sizes. When implanting small valves, the evaluation of PPMp should be used with caution to avoid unexpected PPMm.

Background and Objectives: This scoping review explores the current state of the art of AI-based applications in the field of orthopedics, focusing on its implementation in diagnostic imaging and preoperative planning of knee joint procedures. Materials and Methods: The search was carried out using the recognized scholarly databases PubMed, Medline and Embase and was set to identify original research addressing AI applied to imaging in knee diagnosis and surgical planning, written in English and published up to January 2025. Results: The search produced 1612 papers, of which 36 were included in our review. All papers addressed AI applied to common imaging methods in clinical practice. Of these, thirty integrated AI-based tools with X-rays, one applied AI to X-rays to produce CT-like 3D reproductions, and two studies applied AI to MRI. Conclusions: Several AI tools have already been validated for enhancing the accuracy of measurements and detecting additional parameters in a shorter time compared to standard assessments. We expect these may soon be introduced into routine clinical practice to streamline a number of technical tasks and in some cases to replace the need for human intervention.

Background and Objectives: Bladder cancer (BLCA), intimately associated with the immune system, represents a substantial global health burden due to its high recurrence rates and limited therapeutic effectiveness. Although immunotherapy shows promise, challenges persist due to the lack of reliable therapeutic targets. This study aims to investigate potential immune-related biomarkers that could influence the tumor microenvironment in BLCA, using proteomic and in silico approaches. Materials and Methods: Tissue samples from BLCA patients (n = 27) and controls (n = 27) were collected from Şişli Hamidiye Etfal Training and Research Hospital. Proteomic analysis was performed by liquid chromatography/mass spectrometry (LC-MS)/MS to reveal the identities of differentially regulated proteins. Protein network analysis and hub protein detection were performed using Cytoscape (v.3.10.3), while functional annotation was carried out using EnrichR. The immunological analysis of hub proteins was performed in Sangerbox platform, and prognostic associations were evaluated through the Kaplan-Meier Plotter tool. Results: LC-MS/MS analysis identified 120 differentially regulated immune-related proteins. STRING analysis, using an immune response dataset (GO:0006955), highlighted the complement cascade as a significantly enriched pathway (p < 0.05). Proteins, namely C4A, CFB, C4B, C8B, CFH, CFI, C5, C4BPA, C3, and C2, that are known to play key roles in the complement system were identified. Immunological analysis with these proteins revealed the phenomena of immune infiltration and immune checkpoint gene associations (p < 0.05). Four hub genes-CFB, C4B, CFI, and C2-demonstrated a significant prognostic value for BLCA (p < 0.05). Conclusions: This study highlights the pivotal role of the complement system in the immune regulation of BLCA. CFI, C4A, and C4B emerged as potential target proteins for BLCA treatment, particularly in immunotherapy, for enhancing survival. Future research on these proteins and the complement system specifically focusing on BLCA may facilitate the development of targeted immunotherapies, ultimately improving treatment outcomes.

Background and Objectives: Sport practice, performance satisfaction, and interoception influence physical and mental health. Motor imagery (MI) training improves sensorimotor and cognitive-emotional functions. This study aimed to (a) compare sedentary and artistic gymnastics-practicing young females and (b) evaluate the changes in interoception and performance satisfaction occurring in gymnastics-practicing participants after one month of motor imagery training. Materials and Methods: The difference in interoceptive accuracy (IA) and sensibility (IS) between young sedentary females (Control group, C, n = 27) and age-matched females practicing artistic gymnastics (Experimental group, E, n = 27) were studied using the Interoceptive Accuracy Scale (IAS), the Multisensory Assessment of Interoceptive Awareness (MAIA), and Body Perception Questionnaire (BPQ). The capacity for focusing one's attention on specific tasks (absorption) was assessed by the Tellegen Absorption Scale (TAS). Groups were compared at T0 (before motor imagery training). In group E, the same variables and satisfaction with performance were rated before and after 1 month of motor imagery training. The years of practice and absorption were used as covariates in analyses. Results: (a) Group E exhibited significantly higher scores in the MAIA dimensions than group C and similar BPQ and IAS scores; (b) group E's satisfaction with performance, MAIA, IAS, and BPQ scores increased significantly from T0 to T1. The increase in performance satisfaction became non-significant when using years of practice as the control. The improvement in MAIA dimensions became non-significant when using TAS as the control. Conclusions: Despite the limitations as a result of the absence of an objective evaluation of the performance and physiological correlations of mental imagery and interoceptive accuracy, the baseline differences between the two groups confirm that practicing artistic gymnastics improves interoception. The experience undergone by group E of better performance after training is associated with further improvement in interoceptive intermingled pathways and shared relay stations of sensorimotor and interoceptive information. The results are relevant to the setting up of personalized mental training to improve physical and mental health.

Metabolic dysfunction-associated steatotic fatty liver disease (MASLD) is a worsening global health issue, affecting over one-third of the adult population and representing the leading cause of liver-related morbidity and mortality. MASLD is not only a key precursor to chronic liver disease, but also a systemic condition that leads to numerous extrahepatic complications, increasing the risk of cardiovascular diseases, chronic kidney disease, type 2 diabetes, and certain cancers. The primary reference method for assessing liver fibrosis, allowing for precise determination of its location and severity, remains liver biopsy. However, it is an invasive procedure and involves certain risks. In recent years, the importance of MASLD diagnosis using noninvasive diagnostic methods has been increasing, including serological markers, methods based on multi-omics, and imaging techniques such as liver elastography. This review presents data on the diagnosis and evaluation of this disease that may find application in future clinical practice. The focus is on presenting both currently used and newly identified noninvasive diagnostic methods that open up the prospect of gradually replacing biopsy in the diagnosis of MASLD.

Background and Objectives: Prostatectomy is a common surgical procedure for prostate cancer, the most frequently diagnosed cancer in the male population. The choice of anaesthetic technique has a significant impact on postoperative pain management. The changes in recommendations between 2015 and 2021 prompted this study to evaluate the impact of intrathecal morphine administration in combination with general anaesthesia compared to general anaesthesia alone on postoperative analgesic consumption and the associated side effects. Material and Methods: A single-centre retrospective cohort study was conducted, analysing data from 202 patients who underwent a prostatectomy between 2015 and 2021. Patients were divided into two groups: 147 patients received intrathecal morphine combined with general anaesthesia, while 49 patients received general anaesthesia alone. Key postoperative parameters, including numerical rating scale (NRS) scores, analgesic consumption, and side effects (e.g., nausea, pruritus, hypotension, and respiratory depression) were evaluated. Statistical analyses were performed using Mann-Whitney U-tests and multiple regression models. Results: The group receiving intrathecal morphine showed a significant decrease in NRS pain scores at rest and during movement in the recovery room (p < 0.001). The need for postoperative analgesics, especially opioids such as piritramide, was reduced in this group. No significant increase in serious side effects such as respiratory depression was observed. Conclusions: The present study investigates the potential of intrathecal morphine combined with general anaesthesia as a promising approach to improve pain management in prostatectomy patients. By reducing pain intensity, this method shows significant clinical benefits. In addition, the absence of a significant increase in serious adverse events reinforces the safety of this approach. However, further studies are warranted to assess the long-term outcomes and explore optimal dosing strategies. The reintroduction of this anaesthetic technique has great potential to improve patient recovery and satisfaction following major surgery.

Background/Objectives: Patellofemoral pain syndrome (PFPS) is a common musculoskeletal condition that causes anterior knee pain, often linked to increased joint stress. Rehabilitation typically includes education, strength training, and functional exercises. Recently, telerehabilitation has become a promising alternative, particularly useful in improving access to care in rural areas. This study compares the effects of supervised (SE), web-based (WBE), and self-guided (SGE) exercise programs on pain, functionality, and fear of movement (kinesiophobia) in individuals with PFPS. Materials and Methods: Sixty female patients with PFPS participated in this randomized controlled trial. They were randomly assigned to one of three groups: SE, WBE, or SGE. Each program lasted six weeks, with exercises adjusted based on individual tolerance. Outcomes were assessed using the Kujala Anterior Knee Pain Scale, the visual analog scale (VAS) for pain, the Timed Up and Go Test (TUG) for mobility, and the Tampa Kinesiophobia Scale. Results: All groups showed significant improvements in pain, functionality, and kinesiophobia (p < 0.05). The SE group achieved the greatest improvements across all measures, reducing pain and kinesiophobia while enhancing functionality (p < 0.017). The WBE group also showed significant improvements, outperforming the SGE group in all outcomes (p < 0.017). The SGE group demonstrated the least improvement but still achieved positive changes. Conclusions: Supervised exercise programs were the most effective in managing PFPS symptoms. However, the web-based programs also provided substantial benefits, making them a viable option when in-person supervision is not feasible. Future research should aim to enhance digital interventions for broader accessibility and engagement. Trial Registration: The study protocol was also registered on ClinicalTrials.gov (NCT06625086).

Background and Objectives: Hip surgery is increasingly performed among elderly patients. Oral antithrombotics, which are taken for patients' underlying diseases, are a main concern regarding perioperative bleeding. Postoperative venous thromboembolism (VTE) is a leading cause of mortality after hip surgery. Therefore, administration of preoperative oral antithrombotics is a double-edged sword in hip surgery. In this study, we examined the correlation between the occurrence of postoperative VTE and the type of oral antithrombotics administered preoperatively. Materials and Methods: We analyzed the medical records of 601 patients aged 19 and over who underwent hip surgery from January 2021 to June 2023. The patients were assigned to two groups as follows: Groups VTE+ (patients who developed postoperative VTE) and VTE- (patients who did not develop postoperative VTE), respectively. Results: Of the 139 patients who had been taking oral antithrombotics for 6 months or more, 24 were allocated to group VTE+ and 115 to group VTE-, respectively. The number of patients who took clopidogrel and cilostazol was significantly higher in groups VTE- and VTE+, respectively (12.5 vs. 33.9%, p = 0.038, odds ratio (OR) = 0.278, 95% confidence interval (CI) = 0.078-0.991; 20.8 vs. 5.2%, p = 0.010, 95% CI = 1.325-17.245; group VTE+ vs. group VTE-). Preoperative albumin levels were significantly lower in group VTE+ (3.4 ± 0.6 g/dL vs. 3.7 ± 0.4 g/dL, p = 0.004, OR = 0.285, 95% CI = 0.115-0.702). In multivariate regression analysis, the results were statistically significant for clopidogrel, cilostazol, and preoperative albumin levels (p = 0.035, OR = 0.237, 95% CI = 0.062-0.901; p = 0.011, OR = 6.479, 95% CI = 1.542-27.226; p = 0.002, OR = 0.211, 95% CI = 0.080-0.558). Conclusions: Among the patients who had been taking oral antithrombotics for ≥6 months, clopidogrel had a prophylactic effect, but cilostazol showed an aggravating effect on postoperative VTE in hip surgery. Preoperative hypoalbuminemia increases the risk of postoperative VTE in hip surgery.
