We present a new catalog of 118 ultraluminous infrared galaxies (ULIRGs) and one hyperluminous infrared galaxy (HLIRG) by cross-matching the AKARI all-sky survey with the Sloan Digital Sky Survey Data Release 10 (SDSS DR10) and the final data release of the Two-Degree Field Galaxy Redshift Survey. Forty of the ULIRGs and one HLIRG are new identifications. We find that ULIRGs are interacting pair galaxies or ongoing or postmergers. This is consistent with the widely accepted view: ULIRGs are major mergers of disk galaxies. We confirm the previously known positive trend between the active galactic nucleus fraction and infrared luminosity. We show that ULIRGs have a large offset from the main sequence up to z ∼ 1; their offset from the z ∼ 2 “main sequence” is relatively smaller. We find a result consistent with the previous studies showing that, compared to local star-forming SDSS galaxies of similar mass, local ULIRGs have lower oxygen abundances. We demonstrate for the first time that ULIRGs follow the fundamental metallicity relation (FMR). The scatter of ULIRGs around the FMR (0.09 dex-0.5 dex) is comparable to the scatter of z ∼ 2-3 galaxies. We provide the largest local (0.050

High Mobility Group Box Protein-1 (HMGB1), which has proinflammatory properties, is known to be involved in psychiatric disorders as far as we know, there are only one clinical studies investigating the role of HMGB1 in major depressive disorder (MDD). In this study, we aimed to investigate the role of HMGB1 in the etiopathogenesis of MDD and whether HMGB1 can be used as a biomarker in MDD by measuring the serum HMGB1 levels of depressed patients in the episode and remission periods. This study included 30 patients diagnosed with MDD in episode, 30 patients in remission and 30 healthy controls. Each group comprised 20 female and 10 male participants. In this study, serum HMGB1 levels were found to be lower in the patient group in the episode compared to the patient group in the remission period and the healthy control group. There was no significant difference between the patient group in remission and the healthy control group in terms of serum HMGB1 levels. The fact that serum HMGB1 levels were lower in the patient group in the episode compared to the patient group in the remission period and the control group may be related to the neuroprotective effects of HMGB1. HMGB1 may be used as a biomarker for MDD., Competing Interests: Declaration of competing interest None.

Background: Neonates are relatively prone to immediate, early, and late complications related to central venous cannulation (CVC). Ultrasound-guided brachiocephalic vein (BCV) cannulation has proven to be safe in neonates. Although studies addressed the immediate and early complications of CVC via BCV in neonates, few explored long-term maintenance-related complications., Aims: To evaluate the incidences of long-term maintenance-related complications including central line-associated blood stream infection (CLABSI), central line-associated thrombosis (CLAT), and mechanical complications (CLAMC) of nontunneled BCV cannulation in neonates and their relationship with patient and catheter-related factors., Methods: This study included BCV cannulations of neonates with postconceptional age of ≤44 weeks performed between January 2018 and January 2023. The incidences of complications were determined. Correlations between complications and postconceptional age, body weight, indication for catheter placement, the size and side of the catheter, as well as catheter dwell time were analyzed., Results: In total, 89 BCV cannulations performed in 71 neonates. The incidences were 19.3 [95%CI: 12.88-28.76] total complications, 5.9 [95%CI: 2.84-12.06] CLABSI, 3.4 [95%CI: 1.30-8.58] CLAT and 10.1 [95%CI: 5.76-17.49] CLAMC in 1000 catheter days. There were 23 (25.8%) total complications; 7 (7.9%) were CLABSI, 4 (4.5%) were CLAT, and 12 (13.5%) were CLAMC. The multivariate analysis revealed that prolonged dwell time was associated with high incidence of total complications [OR: 1.07, 95% CI: 1.00-1.14, p = .047] and the catheter of smaller size (3F in this study) was associated with higher incidence of CLABSI [OR: 8.91, 95% CI: 1.03-77.45, p = .047]., Conclusion: In this study, the prolonged dwell time and smaller sized catheter was found to be independent predictors of total complications and CLABSI, respectively. The independent predictive effects of postconceptional age and body weight should be addressed in larger studies as potential risk factors., (© 2024 John Wiley & Sons Ltd.)

Objectives: The objective of this study was to investigate whether residual inhibition (RI), which provides information on the relationship between tinnitus and increased spontaneous activity in the auditory system, is a predictor for the success of sound enrichment treatment., Design: Tinnitus patients were divided into two groups based on whether RI was achieved (RI+) or not (RI-). All participants underwent sound enrichment. Psychosomatic measures (for tinnitus severity, discomfort, attention deficit and sleep difficulties), Tinnitus Handicap Inventory (THI), minimum masking level (MML), and tinnitus loudness level (TLL) results were compared before and at 1, 3, and 6 months after treatment., Study Sample: Sixty-seven chronic tinnitus patients were divided into two groups based on whether RI was achieved (RI+) or not (RI-). There were 38 patients in the RI+ group and 29 in the RI- group., Results: There was a statistically significant difference between the groups in psychosomatic measures, THI, MML and TLL scores at the post-treatment 6 months after treatment (p <.05). There was a statistically significant decrease in psychosomatic measures, THI, MML and TLL scores during the treatment period in the RI+ group, but not in the RI- group., Conclusion: RI may predict the prognosis of tinnitus treatments used in clinics to reduce the spontaneous firing rate of neurons in the central auditory system, and that RI positivity may be a predictor of treatment success in sound enrichment., (© 2024 The Author(s).

Background: Myocardial fibrosis is often detected in patients with hypertrophic cardiomyopathy (HCM), which causes left ventricular (LV) dysfunction and tachyarrhythmias., Purpose: To evaluate the potential value of a machine learning (ML) approach that uses radiomic features from late gadolinium enhancement (LGE) and cine images for the prediction of ventricular tachyarrhythmia (VT) in patients with HCM., Material and Methods: Hyperenhancing areas of LV myocardium on LGE images were manually segmented, and the segmentation was propagated to corresponding areas on cine images. Radiomic features were extracted using the PyRadiomics library. The least absolute shrinkage and selection operator (LASSO) method was employed for radiomic feature selection. Our model development employed the TabPFN algorithm, an adapted Prior-Data Fitted Network design. Model performance was evaluated graphically and numerically over five-repeat fivefold cross-validation. SHapley Additive exPlanations (SHAP) were employed to determine the relative importance of selected radiomic features., Results: Our cohort consisted of 60 patients with HCM (73.3% male; median age = 51.5 years), among whom 17 had documented VT during the follow-up. A total of 1612 radiomic features were extracted for each patient. The LASSO algorithm led to a final selection of 18 radiomic features. The model achieved a mean area under the receiver operating characteristic curve of 0.877, demonstrating good discrimination, and a mean Brier score of 0.119, demonstrating good calibration., Conclusion: Radiomics-based ML models are promising for predicting VT in patients with HCM during the follow-up period. Developing predictive models as clinically useful decision-making tools may significantly improve risk assessment and prognosis., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Cardiovascular diseases (CVDs) are the leading cause of death worldwide. Vital organs like the heart are affected by the occlusion of blood vessels due to atherosclerotic plaque formation. However, the role of infectious agents has always been an essential subject of investigation. This study investigated the presence of microorganisms, including nanobacteria, in atherosclerotic plaques removed from human carotid arteries by microbiological and metagenomic examination., Methods: Atheroma plaque samples were obtained from 20 patients with carotid artery stenosis who had atherectomy by surgery or percutaneous intervention. Nanobacteria were grown by culturing homogenates of the atheroma plaques. Whole genome sequencing was done for samples. Because of the high percentage of Toxoplasma gondii (T. gondii) DNA, PCR investigation was applied to detect T. gondii DNA in the samples., Results: A molecular analysis of nanobacteria revealed them to be made of human proteins, supporting the theory that they are not living organisms. According to sequencing results, samples showed that more than 50 % of the metagenomic sequences belonged to Toxoplasma gondii. PCR investigation indicated that T. gondii DNA was positive in 8 (40 %) of 20 plaques., Conclusions: Further evidence regarding the role of T. gondii in the etiology of plaque formation may help determine the strategy for prevention and treatment of infections in preventing atheroma plaque formation in the future., 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.

Background: Although brief skin cooling (BSC) is widely used in sports medicine and rehabilitation for its positive effects on motor performance, the mechanism underlying this motor facilitation effect remains unclear., Objectives: To explore the hypothesis that BSC enhances muscle force generation, with cold-induced sympathetic activation leading to heightened muscle spindle sensitivity, thereby contributing to this effect., Methods: The study involved two experiments. Experiment 1 included 14 healthy volunteers. Participants submerged their hand in ice water for 3 min. Sympathetic activity was measured via heart rate (HR), muscle force generation was assessed through plantar flexor strength during maximum voluntary contraction (MVC), and cortical contribution to force generation via the volitional wave (V-wave) with and without the cold pressor test (CPT). Experiment-2 involved 11 healthy volunteers and focused on muscle spindle sensitivity and Ia synapse efficacy, assessed using soleus T-reflex and H-reflex recordings before, during, and after CPT., Results: Experiment 1 showed significant increases in HR (7.8%), MVC force (14.1%), and V-wave amplitude (93.4%) during CPT compared to pre-CPT values (p = 0.001, p = 0.03, and p = 0.001, respectively). In Experiment-2, hand skin temperature significantly decreased during CPT and remained lower than pre-CPT after 15 min (p < 0.001). While H-reflex and background EMG amplitudes remained unchanged, T-reflex amplitude (113.7%) increased significantly during CPT and returned to pre-CPT values immediately afterward (p < 0.001). A strong correlation was also observed between HR and T-reflex amplitude (r = 0.916, p = 0.001)., Conclusion: BSC enhances muscle spindle sensitivity via the sympathetic nervous system, promoting more significant muscle force generation. The method used in this study can be safely applied in clinical practice., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

The development of a rapid, sensitive, specific method for detecting foodborne pathogens is paramount for supplying safe food to enhance public health safety. Despite the significant improvement in pathogen detection methods, key issues are still associated with rapid methods, such as distinguishing living cells from dead, the pathogenic potential or health risk of the analyte at the time of consumption, the detection limit, and the sample-to-result. Mammalian cell-based assays analyze pathogens' interaction with host cells and are responsive only to live pathogens or active toxins. In this study, a human embryonic kidney (HEK293) cell line expressing Toll-Like Receptor 5 (TLR-5) and chromogenic reporter system (HEK dual hTLR5) was used for the detection of viable Salmonella in a 96-well tissue culture plate. This cell line responds to low concentrations of TLR5 agonist flagellin. Stimulation of TLR5 ligand activates nuclear factor-kB (NF-κB)-linked alkaline phosphatase (AP-1) signaling cascade inducing the production of secreted embryonic alkaline phosphatase (SEAP). With the addition of a ρ-nitrophenyl phosphate as a substrate, a colored end product representing a positive signal is quantified. The assay's specificity was validated with the top 20 Salmonella enterica serovars and 19 non- Salmonella spp. The performance of the assay was also validated with spiked food samples. The total detection time (sample-to-result), including shortened pre-enrichment (4 h) and selective enrichment (4 h) steps with artificially inoculated outbreak-implicated food samples (chicken, peanut kernel, peanut butter, black pepper, mayonnaise, and peach), was 15 h when inoculated at 1-100 CFU/25 g sample. These results show the potential of HEK-Dual TM hTLR5 cell-based functional biosensors for the rapid screening of Salmonella .

Purpose: To report the safety and efficacy of brolucizumab (Beovu) 6 mg versus aflibercept (Eylea) 2 mg administered every 4 weeks in participants with neovascular age-related macular degeneration (nAMD) and persistent retinal fluid after the week 52 up to week 104., Design: Multicenter, randomized, double-masked phase 3a study., Participants: Participants with recalcitrant nAMD (persistent residual retinal fluid despite previous frequent anti-VEGF treatment)., Methods: Study eyes were randomized 2:1 to intravitreal brolucizumab 6 mg or aflibercept 2 mg every 4 weeks for 100 weeks or until study termination., Main Outcome Measures: All available efficacy (analysis of noninferiority in mean best-corrected visual acuity [BCVA], central subfield thickness [CST], fluid-free status [no intraretinal fluid and no subretinal fluid]) and safety data up to study termination, including data up to week 104 for those participants who completed the study before its termination. All P values after week 52 were nominal and reflect observed data for the efficacy analyses., Results: Brolucizumab 6 mg every 4 weeks was noninferior to aflibercept 2 mg in mean BCVA change from baseline to week 104 (least squares mean difference, -0.4 ETDRS letters; 95% confidence interval [CI], -3.7 to 3.0; P = 0.0169). The proportion of eyes with ≥15-letter loss was 6.2% for brolucizumab and 4.7% for aflibercept (P = 0.7762), and a greater proportion of eyes were fluid free at week 104 (52.5% brolucizumab vs. 28.2% aflibercept; 95% CI, 11.9-37.3; P < 0.001) in eyes treated with brolucizumab versus aflibercept. Incidence of intraocular inflammation (IOI), including retinal vasculitis and retinal vascular occlusion, was 11.5% (0.8% and 2.2%) for brolucizumab versus 6.1% (0% and 0.6%) for aflibercept., Conclusions: Consistent with 52-week results, brolucizumab 6 mg every 4 weeks was noninferior in mean BCVA change, with anatomic outcomes superior to aflibercept 2 mg every 4 weeks from baseline to week 104 or study termination. The incidence of IOI, including retinal vasculitis and retinal vascular occlusion, was higher with brolucizumab versus aflibercept; therefore, brolucizumab should not be used more frequently than every 8 weeks after the loading regimen., Financial Disclosure(s): Proprietary or commercial disclosure may be found after the references., (Copyright © 2024 American Academy of Ophthalmology.

Atrial fibrillation (AF) poses substantial challenges in cardiovascular diseases, impacting patient health and economic burdens. Understanding the mechanical effects of AF on the left atrium (LA) and assessing the influence of treatment modalities on LA functions are critical. This study aims to assess the efficacy of echocardiographic and biochemical parameters in predicting AF recurrence following second generation cryoballoon ablation (CB-2). Ninety-two patients with symptomatic AF, treated with CB-2 at Istanbul University-Cerrahpaşa, Faculty of Medicine, Department of Cardiology, were prospectively examined from January 2021 to July 2023. The study endeavors to develop a predictive model for AF recurrence, investigating the relationship between echocardiographic measurements and serum biomarkers with recurrence. The follow-up duration for echocardiographic assessments and biochemical analyses was systematically documented. The study revealed a significant enhancement in LA mechanical functions during echocardiographic follow-ups three months post-procedure. Specifically, LA strain parameters emerged as significant predictors of recurrence (LAsr: 95%CI 1.004-1.246, p = 0.047; LAsct: 95%CI 1.040-1.750, p = 0.024). Biochemical analyses demonstrated a correlation between elevated PRO-BNP levels and an increased risk of recurrence (95%CI 1.000-1.003, p = 0.012). Moreover, specific biomarkers such as MYBPHL, which demonstrated increased levels post-procedure, were deemed indicative of atrial damage, suggesting potential additional atrial substrate modification beyond PVI. Consequently, improvements in LA function post-cryoballoon ablation and biochemical markers have surfaced as potential indicators for predicting AF recurrence. This study elucidates the effectiveness of CB-2 in treating AF and its impact on LA functions. Notably, LA strain measurements and PRO-BNP levels have emerged as reliable indicators for predicting recurrence. Beyond clinical implications, our research establishes a foundation for a deeper understanding of the role of CB-2 in AF management and factors associated with recurrence., (© 2024.

Objectives: To assess whether nasal breathing improves exercise ventilatory efficiency in patients with heart failure (HF) or chronic coronary syndromes (CCS). Background: Exercise inefficient ventilation predicts disease progression and mortality in patients with cardiovascular diseases. In healthy people, improved ventilatory efficiency with nasal compared to oral breathing was found. Methods: Four study groups were recruited: Patients with HF, patients with CCS, old (age≥45 years) and young (age 20-40 years) healthy control subjects. After a 3-min warm-up, measurements of 5 min with once nasal and once oral breathing were performed in randomized order at 50% peak power on cycle ergometer. Ventilation and gas exchange parameters measured with spiroergometry were analysed by Wilcoxon paired-sample tests and linear mixed models adjusted for sex, height, weight and test order. Results: Groups comprised 15 HF, CCS, and young control and 12 old control. Ventilation/carbon dioxide production ( V ˙ E / V ˙ CO 2 ), ventilation ( V ˙ E ), breathing frequency (f R ), and end-tidal oxygen partial pressure (P ET O 2 ) were significantly lower and tidal volume and end-tidal carbon dioxide partial pressure (P ET CO 2 ) significantly higher during nasal compared to oral breathing in all groups, with large effect sizes for most parameters. For patients with HF, median V ˙ E / V ˙ CO 2 was 35% lower, f R 26% lower, and P ET CO 2 10% higher with nasal compared to oral breathing, respectively. Exercise oscillatory ventilation (EOV) was present in 6 patients and markedly reduced with nasal breathing. Conclusion: Nasal breathing during submaximal exercise significantly improved ventilatory efficiency and abnormal breathing patterns (rapid shallow breathing and EOV) in 80% of our patients with HF and CCS., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Prisca, Pietro, Anja, Laura, Sarina, Dominic, Sabina and Matthias.)

Objective: In previous studies, the results regarding the presence of listening effort or fatigue in tinnitus patients were inconsistent. The reason for this inconsistency could be that extended high frequencies, which can cause listening handicap, were not within normal limits. Therefore, this study aimed to evaluate the listening skills in tinnitus patients by matching the normal hearing thresholds at all frequencies, including the extended high frequency., Methods: Eighteen chronic tinnitus patients and thirty matched healthy controls having normal pure-tone average with symmetrical hearing thresholds was included. Subjects were evaluated with 0.125-20 kHz pure-tone audiometry, Montreal cognitive assessment test (MoCA), Tinnitus Handicap Inventory (THI), Matrix Test, Pupillometry., Results: Pupil dilatation in the 'coding' phase of the sentence presented in tinnitus patients was less than in the control group (p < 0.05). There was no difference between the groups for Matrix test scores (p > 0.05) Also, there was no statistically significant correlation between THI and Pupillometry components nor between MoCA (p > 0.05)., Conclusion: Even though tinnitus patients had normal hearing in the range of 0.125-20 kHz, their autonomic nervous system responses during listening differed from healthy subjects. This difference was interpreted for potential listening fatigue in tinnitus patients., Competing Interests: Declaration of competing interest The authors declare that they have no confict of interest., (Copyright © 2024.

Purpose: The mechanism of tinnitus remains poorly understood; however, studies have underscored the significance of the subcortical auditory system in tinnitus perception. In this study, our aim was to investigate the subcortical auditory system using electrophysiological measurements in individuals with tinnitus and normal hearing. Additionally, we aimed to assess speech-in-noise (SiN) perception to determine whether individuals with tinnitus exhibit SiN deficits despite having normal-hearing thresholds., Methods: A total 42 normal-hearing participants, including 22 individuals with chronic subjective tinnitus and 20 normal individuals, participated in the study. We recorded auditory brainstem response (ABR) and speech-evoked frequency following response (sFFR) from the participants. SiN perception was also assessed using the Matrix test., Results: Our results revealed a significant prolongation of the O peak, which encodes sound offset in sFFR, for the tinnitus group (p < 0.01). The greater non-stimulus-evoked activity was also found in individuals with tinnitus (p < 0.01). In ABR, the tinnitus group showed reduced wave I amplitude and prolonged absolute wave I, III, and V latencies (p ≤ 0.02). Our findings suggested that individuals with tinnitus had poorer SiN perception compared to normal participants (p < 0.05)., Conclusion: The deficit in encoding sound offset may indicate an impaired inhibitory mechanism in tinnitus. The greater non-stimulus-evoked activity observed in the tinnitus group suggests increased neural noise at the subcortical level. Additionally, individuals with tinnitus may experience speech-in-noise deficits despite having a normal audiogram. Taken together, these findings suggest that the lack of inhibition and increased neural noise may be associated with tinnitus perception., (© 2024. The Author(s).)

Purpose: Hearing aid fitting can be challenging when tinnitus accompanies hearing loss, as speech intelligibility and quality of life are affected by both hearing loss and tinnitus perception. However, studies focusing on the optimal hearing aid fitting for this group are scarce. Here, we aim to investigate the performance of alternative hearing aid fitting scenarios in improving hearing aid benefit and managing tinnitus., Methods: Sixty-six participants were included in the study and randomly divided into three groups based on the fitting formula: NAL-NL2, DSL pediatric and hybrid gain fitting procedure (covering NAL-NL2 for low frequencies and DSL pediatric formulas for high frequencies). Hearing aid benefit was evaluated using the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire and speech perception in noise (SPIN). To evaluate tinnitus perception, psychoacoustic characteristics of tinnitus were determined, and the Tinnitus Handicap Inventory (THI) was gathered., Results: The NAL-NL2 fitting procedure showed better results in hearing aid benefit and SPIN compared to the DSL pediatric procedure. In the DSL pediatric procedure, better results were obtained in tinnitus management compared to NAL-NL2. There was no difference between the hybrid fitting procedure and DSL pediatric in tinnitus management. The hybrid fitting procedure also did not differ from NAL-NL2 in SPIN and hearing aid benefit., Conclusion: Here, we propose a hybrid gain fitting procedure that can be a better alternative to boost hearing aid performance and tinnitus management in clinical practice., (© 2024.

Objective: Tinnitus retraining therapy (TRT) has been widely used in tinnitus management. However, its efficacy is often assessed through subjective methods. Here, we aimed to assess potential neural changes following TRT using mismatch negativity (MMN)., Design: Chronic tinnitus (>6 months) patients participated in a six-month TRT program. We collected tinnitus psychoacoustic features and gathered the tinnitus handicap inventory (THI) before and after TRT. We also used a multi-featured paradigm, including frequency, intensity, duration, location and silent gap deviants, to elicit MMN response before and after TRT. Data were analyzed retrospectively., Study Sample: The study involved 26 chronic tinnitus patients., Results: Post-TRT measurements showed that MMN amplitudes significantly increased for all deviant conditions (p ≤ .03). However, we did not find a significant difference in MMN latencies for all deviant conditions (p ≥ .13). The THI scores of the patients significantly decreased following the TRT program ( p  < 0.001). Our results reveal improved subjective tinnitus perception following the TRT program., Conclusion: These findings indicate that TRT might be a viable alternative in tinnitus management. The greater MMN amplitudes and improved subjective tinnitus perception raise the possibility that MMN can be a useful tool in tinnitus research and tinnitus patient follow-up.

Patients on double antiplatelet treatment who need early in-hospital coronary artery bypass grafting (CABG) are at high risk of major bleeding. In this study, we aimed to investigate the impact of ticagrelor preloading on CABG related bleeding in patients with ST-segment elevation myocardial infarction (STEMI) initially managed with primary percutaneous coronary intervention (pPCI). Patients with the diagnosis of STEMI who were managed with pPCI and underwent subsequent early (4-7 days following pPCI) or delayed (> 7 days following pPCI) on-pump CABG surgery were included. All study patients were preloaded with ticagrelor 180 mg prior to pPCI procedure. Patients' demographics, clinical variables, and short-term cardiovascular outcomes were recorded. This is a retrospective study which included 98 patients. Fifty-four (54%) patients underwent early and 44 (45%) patients underwent delayed CABG surgery. CABG-related bleeding occurred in 22 (22.4%) patients. There was no significant difference with respect to total ticagrelor dose and timing of the surgery between patients with or without CABG-related bleeding (p: 0.165 and p: 0.142). Multivariate analyses demonstrated that only preoperative hemoglobin level < 10.9 and use of mechanical cardiac support devices were independent predictors of CABG-related bleeding [OR: 3719, p: 0.009 and OR: 11,698, p: 0.004, respectively].There were three deaths within the 30 days of surgery, all occurring in patients with CABG-related bleeding. However, CABG-related bleeding was not associated with long-term cardiovascular events during the follow-up. Our results indicated that discontinuation of ticagrelor therapy 3 days prior to surgery is sufficient to avoid CABG-related bleeding. Moreover, early CABG following STEMI does not increase the risk of long-term cardiovascular events., (© 2024. Springer Nature Japan KK, part of Springer Nature.)

Purpose: Congenital aortic stenosis is a common pathology in the childhood age group and its clinical spectrum varies between asymptomatic and severe heart failure. In our study, we planned to evaluate the long-term results of patients who underwent balloon aortic valvuloplasty (BAV) due to critical aortic valve stenosis in our clinic., Materials and Methods:  Patients aged 0-18 years who underwent aortic balloon valvuloplasty due to aortic stenosis in our clinic between January 2002 and January 2022 were retrospectively evaluated., Results: Among the 48 patients who underwent balloon valvuloplasty due to aortic stenosis, 13 (27%) were female, and 35 (73%) were male. The median age at the time of the procedure was 27.5 months (IQR: 4-96), the median weight was 9.9 kg (IQR: 5.40-29.50), and the median height was 79 cm (IQR: 54-133). The median follow-up duration was 93.5 months (IQR: 38-132). Angiographic assessments in all patients revealed a median left ventricular pressure of 160 mmHg (IQR: 140-200) and a median pressure gradient between the left ventricle and the aorta of 60 mmHg (IQR: 42-80). The median balloon diameter used was 10 mm (IQR: 8-12). Post-procedural measurements showed a median mean gradient of 30 mmHg (IQR: 20-35) between the left ventricle and the aorta. The procedure was successful in 45 (93.5%) patients. During follow-up, 11 patients required surgical intervention. Ross procedure was performed in five patients, homograft in five patients, and mechanical valve implantation in one patient. Risk factors for the need for surgical intervention were evaluated in detail. During the follow-up, the risk factor for intervention was determined to be aortic insufficiency., Conclusion: Aortic valve balloon valvuloplasty is a safe and successful treatment method for critical aortic stenosis. It should be the first choice of treatment option in suitable patients., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Objective: This study is an addition to the already published prospective randomized double-blinded trial by Tschiedel et al. that compared two different sedation regimes in fiberoptic flexible bronchoscopy in pediatric subjects. The objective of the presented study is to analyze the correlation between the neutrophil percentage of the bronchoalveolar lavage fluid (BALF) and coughing episodes during bronchoscopy., Methods: Fifty subjects, aged 1-17 years, received flexible fiberoptic bronchoscopy under deep sedation. The BALF of 39 subjects was analyzed with reference to cytology and microbiology., Results: The percentage of neutrophils from the total cell count ranged from 0% to 95.3% (median 2.7). Nineteen patients (49%) had a percentage of ≥3.0%. Pearson's correlation showed a high correlation ( r  = 0.529, p  = 0.001) between the coughing episodes per minute and the neutrophil percentage in the BALF. Analysis of variance showed a significant difference in neutrophil percentage between the indication groups ( p  = 0.013). The t -test ( p  = 0.019) showed a significant difference between the neutrophil percentage for patients with a probable airway infection under immunosuppression (median 2.9) and patients with cystic fibrosis (median 49.6). The linear regression analysis showed a significantly stronger impact of the neutrophil percentage on coughing frequency than the sedation regime ( β neutrophils  = 0.526 with p  = 0.001 vs. β sedation  = 0.165 with p  = 0.251)., Conclusion: When bronchoscopy is to be performed on a pediatric patient with suspected bacterial or viral infection, and therefore neutrophilic airway inflammation, coughing is to be expected., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Danino, Stehling, Eckerland, Orhan and Tschiedel.)

Background: Cleft lip and palate (CLCP) surgeries necessitate precise airway management, especially in pediatric cases with anatomical variations. The Covid-19 pandemic posed unprecedented challenges to anesthesiology practices that required adaptations to ensure patient safety and minimize viral transmission. Videolaryngoscopy (VL) emerged as a valuable tool in airway management during the pandemic, offering improved intubation success rates and reduced aerosol generation risks., Methods: This retrospective study compared anesthesiology practices in CLCP surgeries before (2015-2019) and during the Covid-19 (2019-2022) pandemic at a tertiary care center. Patient demographics, anesthesia techniques, intubation difficulty, airway management, and intraoperative and postoperative follow-up were analyzed from anesthesia records., Results: This study included 1282 cases. Demographics were similar between periods. During the pandemic, there was a significant decrease in the number of patients under one year old (p < 0.001) and a higher prevalence of micrognathia and comorbidities (p = 0.001 and p = 0.038, respectively). Difficult intubation and intraoperative complication rates decreased during the pandemic, but they were not statistically significant. VL usage during the pandemic contributed to improved extubating success (p < 0.001)., Conclusions: VL usage and improved patient outcomes were observed during the pandemic, potentially due to proactive measures and infection control protocols. Decision-making processes for extubation and intensive care unit stay became crucial during the pandemic. Understanding the role of VL and its adaptations during the Covid-19 pandemic is vital for optimizing perioperative care in CLCP surgeries and other procedures requiring airway management. The findings highlight the resilience of healthcare systems and the importance of evidence-based practices under challenging circumstances., (Copyright © 2024 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Objective: The aim of this study was to examine the quality of life and behavioral disorders in children with obstructive sleep apnea (OSA) or primary snoring, as well as how these problems changed after monobloc treatment., Methods: Fourteen children with primary snoring and 16 children with OSA who had skeletal class II malocclusion due to mandibular retrognathia were treated with monobloc appliances. To investigate the relationship between behavioral disorders and quality of life, parents were asked to complete four questionnaires: attention deficit and hyperactivity disorder (ADHD) scale, strength and difficulties questionnaire (SDQ), pediatric sleep questionnaire (PSQ), and Pittsburgh sleep quality scale (PSQS). Mann-Whitney U and Wilcoxon signed-rank tests were used to evaluate the data., Results: According to the results of the PSQ and PSQS, an increase in sleep quality was observed after monobloc treatment. The decrease in the total ADHD score at the end of the treatment was found to be statistically significant in both the OSA (p<0.01) and snoring (p<0.01) groups. According to the SDQ scores, the increase in the social behavior score and the decrease in the peer bullying score in the snoring group were statistically significant (p<0.05)., Conclusion: The use of a monobloc appliance in pediatric patients exhibiting primary snoring and OSA resulted in a notable reduction in sleep-breathing disorder symptoms and a notable enhancement in their overall quality of life. Based on the analyses of the questionnaires, it was concluded that the increase in sleep quality improved the pediatric patients' quality of life after orthodontic treatment with orthodontic monobloc appliances., Competing Interests: Declaration of Interests: The authors declare no conflict of interest., (Copyright© 2024 The Author.

Objectives: To report ocular manifestations in patients with Fabry disease (FD) from a tertiary eye care center in Türkiye., Materials and Methods: This prospective, cross-sectional study included 30 eyes of 15 patients with FD. The diagnosis of FD was made based on a combination of clinical findings, genetic analysis, and biochemical evaluation. All participants underwent a detailed ophthalmic examination with special focus on the typical ocular features of FD (cornea verticillata, conjunctival aneurysms, cataract, retinal vessel tortuosity)., Results: The mean age was 45±17 years (range: 22-75 years), with a female/male ratio of 2:3. All patients had tortuous conjunctival vessels and 12 patients (80%) had conjunctival aneurysms. Cornea verticillata was present in 10 patients (66.6%), lens opacification in 4 patients (26.6%), and retinal vascular tortuosity in 8 patients (53.3%). All patients had at least two different ocular findings; most (3 heterozygotes/7 hemizygotes) had a combination of corneal verticillata and conjunctival vessel abnormality. The conjunctiva, cornea, and retina were affected together in 5 hemizygous patients (33.3%). One hemizygous patient had all FDrelated ocular manifestations in both eyes., Conclusion: To our knowledge, this study is the first to describe the ocular manifestations of FD in the Turkish population. Although cornea verticillata is considered a hallmark of FD, it was absent in approximately one-third of patients. Moreover, cataract, another well-known feature of FD, was present in only 26.6% of the patients. Conjunctival vascular abnormality alone seems to be quite rare in FD, although it often accompanies other ocular manifestations. Therefore, recognition of other mild findings and special consideration of their associations may increase the diagnostic value of ocular findings in FD., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors., (©Copyright 2024 by the Turkish Ophthalmological Association / Turkish Journal of Ophthalmology published by Galenos Publishing House.)

Introduction: Clear aligner technology based on a machine learning algorithm is currently available for orthodontic treatment. Treatment planning on the basis of 3-dimensional crown, root, and bone imaging is claimed to provide accurate diagnosis and better treatment outcomes for adult patients with complex needs. This study aimed to answer the following questions: (1) would practitioners modify their original treatment plan once provided with the crown, root, and bone view? and (2) does practitioner satisfaction regarding treatment outcomes change once the crown, root, and bone view is provided?, Methods: An online questionnaire was emailed to members of the American Association of Orthodontists (n = 2300) and the Virginia Orthodontic Education and Research Foundation (n = 211). The survey consisted of videos of 4 patients shown in 2 presentations: crown-only and crown, root, and bone views, generated by artificial intelligence-driven treatment planning software (3D Predict aligner system; 3D Predict, New York, NY). Respondents were asked to answer treatment-related questions and rate the treatment outcomes using a visual analog scale. Statistical analyses were completed to determine the significance of crown, root, and bone view on treatment planning with clear aligners., Results: A total of 70 orthodontists participated in the survey. There were significant differences in responses when viewing patients in crown-only and crown, root, and bone presentations. Across the 4 patients, 33%-43% of practitioners changed their sentiment toward the treatment plan (P <0.001). When rating satisfaction on the 100-point scale, average ratings changed by 10.6 to 21.0 points; both increases and decreases in satisfaction were seen across the patients (P <0.001)., Conclusions: When given 3-dimensional information on the position of a patient's crowns, root, and bone coverage, orthodontists are likely to change their clear aligner treatment plan. This study showed that a confirmation of dehiscence and fenestrations using the root and bone view resulted in practitioner dissatisfaction despite an initial satisfaction with the crown-only view., (Copyright © 2024 American Association of Orthodontists.

Objective: This study aims to control all hearing thresholds, including extended high frequencies (EHFs), presents stimuli of varying difficulty levels, and measures electroencephalography (EEG) and pupillometry responses to determine whether listening difficulty in tinnitus patients is effort or fatigue-related., Methods: Twenty-one chronic tinnitus patients and 26 matched healthy controls having normal pure-tone averages with symmetrical hearing thresholds were included. Subjects were evaluated with 0.125-20 kHz pure-tone audiometry, Montreal Cognitive Assessment Test (MoCA), Tinnitus Handicap Inventory (THI), EEG, and pupillometry., Results: Pupil dilatation and EEG alpha power during the "encoding" phase of the presented sentence in tinnitus patients were less in all listening conditions (p < .05). Also, there was no statistically significant relationship between EEG and pupillometry components for all listening conditions and THI or MoCA (p > .05)., Conclusion: EEG and pupillometry results under various listening conditions indicate potential listening effort in tinnitus patients even if all frequencies, including EHFs, are controlled. Also, we suggest that pupillometry should be interpreted with caution in autonomic nervous system-related conditions such as tinnitus., (© 2024 The Author(s).

Background: Advancements in artificial intelligence are being seen in multiple fields, including medicine, and this trend is likely to continue going forward. To analyze the accuracy and reproducibility of ChatGPT answers about acute coronary syndromes (ACS)., Methods: The questions asked to ChatGPT were prepared in two categories. A list of frequently asked questions (FAQs) created from inquiries asked by the public and while preparing the scientific question list, 2023 European Society of Cardiology (ESC) Guidelines for the management of ACS and ESC Clinical Practice Guidelines were used. Accuracy and reproducibility of ChatGPT responses about ACS were evaluated by two cardiologists with ten years of experience using Global Quality Score (GQS)., Results: Eventually, 72 FAQs related to ACS met the study inclusion criteria. In total, 65 (90.3%) ChatGPT answers scored GQS 5, which indicated highest accuracy and proficiency. None of the ChatGPT responses to FAQs about ACS scored GQS 1. In addition, highest accuracy and reliability of ChatGPT answers was obtained for the prevention and lifestyle section with GQS 5 for 19 (95%) answers, and GQS 4 for 1 (5%) answer. In contrast, accuracy and proficiency of ChatGPT answers were lowest for the treatment and management section. Moreover, 68 (88.3%) ChatGPT responses for guideline based questions scored GQS 5. Reproducibility of ChatGPT answers was 94.4% for FAQs and 90.9% for ESC guidelines questions., Conclusions: This study shows for the first time that ChatGPT can give accurate and sufficient responses to more than 90% of FAQs about ACS. In addition, proficiency and correctness of ChatGPT answers about questions depending on ESC guidelines was also substantial.

Objective: Previous studies have focused on the balance system's involvement in sleep deprivation or disorders. This study investigated how daily routine sleep quality affects the balance system of people without sleep deprivation or diagnosed sleep disorders., Methods: The study included 45 participants with a BMI score of <25. The PSQI was used to determine sleep quality. The SOT, HS-SOT, and ADT evaluated the vestibular system's functionality., Results: In SOT, condition 3, 4, 5, and 6 composite scores, VIS and VEST composite balance scores, and HS-SOT 5 scores were lower in the HPSQI group. At the same time, there is a statistically significant negative correlation between these scores and PSQI scores., Conclusion: Poor sleep quality may be a factor influencing the balance system. Sleep quality affects the visual and vestibular systems rather than the somatosensory system. The population should be made aware of this issue, and clinicians should consider the potential impact of sleep quality when evaluating the balance system., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2024 Elsevier Inc.

Introduction: To assess real-world safety outcomes for adults with neovascular age-related macular degeneration (nAMD) treated with brolucizumab from the US-based IRIS® (Intelligent Research in Sight) Registry., Methods: In this retrospective study, 18,312 eyes (15,998 patients) treated with ≥ 1 intravitreal brolucizumab injections between 8 October 2019 (US launch date for brolucizumab) and 7 October 2021 were followed up for ≤ 2 years after first injection (index date). The study assessed the predefined incident ocular adverse events of intraocular inflammation (IOI), retinal vasculitis (RV), and retinal vascular occlusion (RO)., Results: Overall, 614/18,312 eyes (3.4%) experienced any IOI, RV, and/or RO event. Median (interquartile range [IQR]) time to an event was 84 (42-167) days; 77.4% of events (475/614) occurred within 6 months after index date. Median (IQR) number of brolucizumab injections before an event was 2 (1-4). For eyes with an adverse event and visual acuity (VA) data (n = 406), median (IQR) change in Early Treatment of Diabetic Retinopathy Study (ETDRS) letters from pre-event VA was 0 (- 7 to + 5) at the 6-month follow-up; 50 eyes (12.3%) had a VA loss of 10 or more ETDRS letters. Risk of an event (hazard ratio [95% confidence interval]) was decreased in eyes from male patients (0.61 [0.53-0.71]), from older patients (0.83 [0.76-0.90]), from treatment-naive patients (0.51 [0.38-0.69]), and from patients who started brolucizumab in the second year after launch (0.68 [0.53-0.86] vs. first year)., Conclusion: In this large real-world brolucizumab safety study, 3.4% of eyes experienced an IOI, RV, and/or RO event. Among eyes that experienced an adverse event for which VA data were available, median ETDRS vision change was 0 letters (IQR - 7 to + 5)., (© 2024. The Author(s).)

Although antibodies, a key element of biorecognition, are frequently used as biosensor probes, the use of these large molecules can lead to adverse effects. Fab fragments can be reduced to allow proper antigen-binding orientation via thiol groups containing Fab sites that can directly penetrate Au sites chemically. In this study, the ability of the surface plasmon resonance (SPR) sensor to detect Salmonella was studied. Tris(2-carboxyethyl)phosphine was used as a reducing agent to obtain half antibody fragments. Sensor surface was immobilized with antibody, and bacteria suspensions were injected from low to high concentrations. Response units were changed by binding first reduced antibody fragments, then bacteria. The biosensor was able to determine the bacterial concentrations between 10 3 and 10 8  CFU/mL. Based on these results, the half antibody fragmentation method can be generalized for faster, label-free, sensitive, and selective detection of other bacteria species., (© 2024 John Wiley & Sons Ltd.)

Objective: In previous animal studies, sound enhancement reduced tinnitus perception in cases associated with hearing loss. The aim of this study was to investigate the efficacy of sound enrichment therapy in tinnitus treatment by developing a protocol that includes criteria for psychoacoustic characteristics of tinnitus to determine whether the etiology is related to hearing loss., Methods: A total of 96 patients with chronic tinnitus were included in the study. Fifty-two patients in the study group and 44 patients in the placebo group considered residual inhibition (RI) outcomes and tinnitus pitches. Both groups received sound enrichment treatment with different spectrum contents. The tinnitus handicap inventory (THI), visual analog scale (VAS), minimum masking level (MML), and tinnitus loudness level (TLL) results were compared before and at 1, 3, and 6 months after treatment., Results: There was a statistically significant difference between the groups in THI, VAS, MML, and TLL scores from the first month to all months after treatment (p < .01). For the study group, there was a statistically significant decrease in THI, VAS, MML, and TLL scores in the first month (p < .01). This decrease continued at a statistically significant level in the third month of posttreatment for THI (p < .05) and at all months for VAS-1 (tinnitus severity) (p < .05) and VAS-2 (tinnitus discomfort) (p < .05)., Conclusion: In clinical practice, after excluding other factors related to the tinnitus etiology, sound enrichment treatment can be effective in tinnitus cases where RI is positive and the tinnitus pitch is matched with a hearing loss between 45 and 55 dB HL in a relatively short period of 1 month., (© 2024 The Authors.

Abstract: Pretreatment with an oral P2Y12 receptor blocker (before coronary angiography) versus treatment in the catheterization laboratory has been a matter of debate in patients presenting with non-ST segment elevation myocardial infarction (NSTEMI). The primary aim of this study was to assess the impact of an immediate preloading strategy with ticagrelor on periprocedural myocardial injury in patients with NSTEMI treated with an early invasive strategy. NSTEMI patients who underwent coronary angiography and subsequent percutaneous coronary intervention (PCI) within 24 hours after hospital admission were divided into 2 groups: the first group (pretreatment group) included patients who received ticagrelor pretreatment as soon as possible after admission and the second group (no pretreatment group) included patients who received a loading dose of ticagrelor after coronary angiography. The pretreatment group included 232 patients, and the no pretreatment group included 87 patients. Male patients represented the majority of the patients. The 2 groups were similar in baseline characteristics, except for a greater incidence of hypertension ( P = 0.014) and higher hemoglobin levels ( P = 0.01) in the pretreatment group in comparison with the no pretreatment group. Patients in the ticagrelor pretreatment group had less myocardial injury until coronary angiography based on troponin measurements collected at 12 hours after admission ( P = 0.025). Patients in the ticagrelor pretreatment group also had fewer periprocedural myocardial injuries based on troponin measurements taken between 12 and 24 hours after the PCI ( P = 0.026 and P = 0.022, respectively). Our findings suggested that ticagrelor pretreatment reduces periprocedural myocardial injury in NSTEMI patients who underwent PCI within 24 hours after admission., Competing Interests: The authors report no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose: Transcatheter closure is the first-line treatment option for hemodynamically significant secundum atrial septal defects (ASDs). This study examines our center's experience with this procedure over the last 15 years., Materials and Methods: Pediatric patients aged 0-18 years with secundum ASDs who were planned for transcatheter closure in our clinic between January 2007 and January 2023 were retrospectively evaluated., Results: Transcatheter secundum ASD closure was planned for a total of 334 patients during the study period: 191 girls (57.2%) and 143 boys (42.8%). Their mean age was 8.08±3.9 years, and their mean weight was 30±15.6 kg. Defect diameter measured transesophageally ranged from 5 to 35 mm, with a mean of 12.56±4.02 mm. Transesophageal echocardiographic examination revealed a single secundum ASD in 319 patients (95.5%) and multiple secundum ASDs in 15 patients (4.5%). In 11 patients (3.3%), the procedure was terminated before initiating transcatheter ASD closure because of insufficient vena cava rims or a very large or multi-fenestrated defect. The 323 patients (96.7%) who underwent transcatheter ASD closure had a mean pulmonary artery pressure of 15.1±4.0 mmHg and a mean Qp/Qs ratio of 1.97±0.56. The procedure failed in four patients (1.3%) because of device embolization (n=2) or the inability to properly position the device (n=2). Major complications other than device embolization observed during or after transcatheter closure included anesthetic-induced respiratory depression (n=1) and total atelectasis of the lung (n=1). No new major complications were detected during the patients' long-term follow-up., Conclusion: With appropriate patient and device selection, transcatheter closure is a safe and effective treatment for secundum ASD and should be the first treatment of choice., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Doğan et al.)

Background: Currently, the primary treatment for gastroesophageal reflux is acid suppression with proton pump inhibitors, but they are not a cure, and some patients don't respond well or refuse long-term use. Therefore, alternative therapies are needed to understand the disease and develop better treatments. Laparoscopic anti-reflux surgery (LARS) can resolve symptoms of these patients and plays a significant role in evaluating esophageal healing after preventing harmful effects. Successful LARS improves typical gastroesophageal reflux symptoms in most patients, mainly by reducing the exposure time to gastric contents in the esophagus. Amelioration of the inflammatory response and a recovery response in the esophageal epithelium is expected following the cessation of the noxious attack., Aim: To explore the role of inflammatory biomolecules in LARS and assess the time required for esophageal epithelial recovery., Methods: Of 22 patients with LARS (pre- and post/5.8 ± 3.8 months after LARS) and 25 healthy controls (HCs) were included. All subjects underwent 24-h multichannel intraluminal impedance-pH monitoring and upper gastrointestinal endoscopy, during which esophageal biopsy samples were collected using endoscopic techniques. Inflammatory molecules in esophageal biopsies were investigated by reverse transcription-polymerase chain reaction and multiplex-enzyme-linked immunosorbent assay., Results: Post-LARS samples showed significant increases in proinflammatory cytokines [interleukin (IL)-1β, interferon-γ, C-X-C chemokine ligand 2 (CXCL2)], anti-inflammatory cytokines [CC chemokine ligand (CCL) 11, CCL13, CCL17, CCL26, CCL1, CCL7, CCL8, CCL24, IL-4, IL-10], and homeostatic cytokines (CCL27, CCL20, CCL19, CCL23, CCL25, CXCL12, migration inhibitory factor) compared to both HCs and pre-LARS samples. CCL17 and CCL21 levels were higher in pre-LARS than in HCs ( P < 0.05). The mRNA expression levels of AKT1, fibroblast growth factor 2, HRAS, and mitogen-activated protein kinase 4 were significantly decreased post-LARS vs pre-LARS. CCL2 and epidermal growth factor gene levels were significantly increased in the pre-LARS compared to the HCs ( P < 0.05)., Conclusion: The presence of proinflammatory proteins post-LARS suggests ongoing inflammation in the epithelium. Elevated homeostatic cytokine levels indicate cell balance is maintained for about 6 months after LARS. The anti-inflammatory response post-LARS shows suppression of inflammatory damage and ongoing postoperative recovery., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2024.

Objectives: This study aimed to assess the clinical outcomes and risk factors for severe coronavirus disease 2019 (COVID-19) in patients with inflammatory rheumatic disease (IRD) of a national cohort., Patients and Methods: The multicenter cross-sectional study was carried out between July 15, 2020, and February 28, 2021. Data collection was provided from a national network database system, and 3,532 IRD patients (2,359 males, 1,173 females; mean age: 48.7±13.9 years; range; 18 to 90 years) were analyzed. Demographics, clinics about rheumatic disease, comorbidities, smoking status, being infected with COVID-19, and the course of the infection were questioned by rheumatology specialists., Results: One hundred seventeen patients were infected with COVID-19, the hospitalization rate due to COVID-19 was 58.9%, and the mortality rate was 1.7%. There was no difference between the COVID-19 positive and negative groups in terms of rheumatic disease activities and receiving drugs. It was observed that patients with COVID-19 had worse compliance with isolation rules, and bacillus Calmette-Guérin (BCG) vaccination was less common. The mean age and the rate of smoking of hospitalized COVID-19 patients were higher than those without hospitalization., Conclusion: In this cohort, in which real-life data were analyzed, COVID-19 rates in IRD patients were similar to the general population for the same period. Compliance with the isolation rules and BCG vaccination attracted attention as components that reduce the risk of COVID-19 infection. The risk factors for hospitalization were older age and smoking., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2024, Turkish League Against Rheumatism.)

Background/aim: To investigate the relationship between sex-related visceral obesity and WHO/ISUP nuclear grade in clear cell renal cell carcinoma (ccRCC)., Materials and Methods: Between January 2018 and June 2022, 95 patients (56 men and 39 women) with pathologically proven ccRCC who underwent abdominal computed tomography examination were retrospectively examined. The patients were classified into two groups: low- and high-WHO/ISUP nuclear grade ccRCC (n = 58 and n = 37), respectively. Patient height, weight, body mass index (BMI), sex, age, subcutaneous fat area (SFA), visceral fat area (VFA), total fat area (TFA), and percentage of visceral fat (VF%) were recorded for the two groups., Results: No significant differences were found in age, BMI, SFA, or TFA, but VFA and VF% were significantly higher in the high-grade patient group. In males, maximal tumor diameter (MTD) (67.8% sensitivity and 76.9% specificity) had the highest area under the curve (AUC), while in females, VF% (70.0% sensitivity and 73.7% specificity) had the highest AUC. VF% revealed an odds ratio (OR) of 1.09 in females with high-grade ccRCC, and in males, MTD was an independent predictor of ccRCC with an OR of 1.03., Conclusions: Sex-related body fat tissue, including VFA and VF%, could be used for estimating WHO/ISUP nuclear grade in patients with ccRCC, especially in females., Competing Interests: Conflict of interest: The authors declare that there are no conflicts of interest., (© TÜBİTAK.)

Background: Hypertrophic cardiomyopathy (HCM) is a genetically inherited cardiac disorder with diverse clinical presentations. Adrenergic activity, primarily mediated through beta-adrenoceptors, plays a central role in the clinical course of HCM. Adrenergic stimulation increases cardiac contractility and heart rate through beta-1 adrenoceptor activation. Beta-blocker drugs are recommended as the primary treatment for symptomatic HCM patients to mitigate these effects., Methods: This prospective study aimed to investigate the impact of common ADRB-1 gene polymorphisms, specifically serine-glycine at position 49 and arginine-glycine at position 389, on the clinical and structural aspects of HCM. Additionally, the study explored the association between these genetic variations and the response to beta-blocker therapy in HCM patients., Results: A cohort of 147 HCM patients was enrolled, and comprehensive assessments were performed. The findings revealed that the Ser49Gly polymorphism significantly influenced ventricular ectopic beats, with beta-blocker therapy effectively reducing them in Ser49 homozygous patients. Moreover, natriuretic peptide levels decreased, particularly in Ser49 homozygotes, indicating improved cardiac function. Left ventricular outflow obstruction, a hallmark of HCM, was also reduced following beta-blocker treatment in all patient groups. In contrast, the Arg389Gly polymorphism did not significantly impact baseline parameters or beta-blocker response., Conclusion: These results emphasize the role of the Ser49Gly polymorphism in the ADRB-1 gene in shaping the clinical course and response to beta-blocker therapy in HCM patients. This insight may enable a more personalized approach to managing HCM by considering genetic factors in treatment decisions. Further research with larger populations and longer follow-up periods is needed to confirm and expand upon these findings.
