Syntax drives default language selection in bilingual connected speech production.

The present study investigated the role of syntactic processing in driving bilingual language selection. In two experiments, 120 English-dominant Spanish-English bilinguals read aloud 18 paragraphs with language switches. In Experiment 1a, each paragraph included eight switch words on function targets (four that repeated in every paragraph), and Experiment 1b was a replication with eight additional switches on content words in each paragraph. Both experiments had three conditions: (a) normal, (b) noun-swapped (in which nouns within consecutive sentences were swapped), and (c) random (in which words in each sentence were reordered randomly). In both experiments bilinguals produced intrusion errors, automatically translating language switch words by mistake, especially on function words (e.g., saying the day and stay awake instead of the day y stay awake). Intrusion rates did not vary across experiments even though switch rate was doubled in Experiment 1b relative to Experiment 1a. Bilinguals produced the most intrusions in normal paragraphs, slightly but significantly fewer intrusions in noun-swapped paragraphs, and a dramatic drop in intrusion rates in the random condition, even though the random condition elicited the most within-language errors. Bilinguals also demonstrated a common signature of inhibitory control in the form of reversed language dominance effects, which did not vary significantly across paragraph types. Finally, intrusions increased with switch word predictability (surprisal), but significant differences between conditions remained when controlling for predictability. These results demonstrate that bilingual language selection is driven by syntactic processing, which operates independently from other language control mechanisms, such as inhibition.the day and stay (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Research on Cattle Behavior Recognition and Multi-Object Tracking Algorithm Based on YOLO-BoT.

In smart ranch management, cattle behavior recognition and tracking play a crucial role in evaluating animal welfare. To address the issues of missed and false detections caused by inter-cow occlusions and infrastructure obstructions in the barn environment, this paper proposes a multi-object tracking method called YOLO-BoT. Built upon YOLOv8, the method first integrates dynamic convolution (DyConv) to enable adaptive weight adjustments, enhancing detection accuracy in complex environments. The C2f-iRMB structure is then employed to improve feature extraction efficiency, ensuring the capture of essential features even under occlusions or lighting variations. Additionally, the Adown downsampling module is incorporated to strengthen multi-scale information fusion, and a dynamic head (DyHead) is used to improve the robustness of detection boxes, ensuring precise identification of rapidly changing target positions. To further enhance tracking performance, DIoU distance calculation, confidence-based bounding box reclassification, and a virtual trajectory update mechanism are introduced, ensuring accurate matching under occlusion and minimizing identity switches. Experimental results demonstrate that YOLO-BoT achieves a mean average precision (mAP) of 91.7% in cattle detection, with precision and recall increased by 4.4% and 1%, respectively. Moreover, the proposed method improves higher order tracking accuracy (HOTA), multi-object tracking accuracy (MOTA), multi-object tracking precision (MOTP), and IDF1 by 4.4%, 7%, 1.7%, and 4.3%, respectively, while reducing the identity switch rate (IDS) by 30.9%. The tracker operates in real-time at an average speed of 31.2 fps, significantly enhancing multi-object tracking performance in complex scenarios and providing strong support for long-term behavior analysis and contactless automated monitoring.

High-Performance Electro-optical Dual-Mode Color-Changing and Energy Storage Device Based on Mo-Doped WO3 and TiO2/NiO Thin Films.

Under optical and electrical control, a multifunctional electro-optical dual-control color-changing and energy storage device not only realizes fast color conversion but also achieves good energy storage performance. In this work, Mo-doped WO3 (Mo-WO3) films were prepared by a one-step hydrothermal method, among which the 2 at. % Mo-doped WO3 film has the best electrochromic and energy storage performance. Meanwhile, TiO2/NiO composite films were prepared by the hydrothermal method and electrodeposition method. The TiO2/NiO/N719 photoanode was prepared by the dip-dyeing method on the TiO2/NiO composite film. The results show that the TiO2/NiO-10s/N719 composite film has excellent photoelectric conversion and energy storage properties. Finally, choosing Mo-WO3 as the cathode and the TiO2/NiO/N719 film as the anode, a multifunctional electro-optical dual-control Mo-WO3@TiO2/NiO/N719 color-changing and energy storage device was constructed. Under electrical control, it shows a fast color switching rate (the coloring/bleaching time is 4.1/2.9 s), excellent coloration efficiency (62.1 cm2/C), obviously improved area capacitance (90.4 mF/cm2), and excellent cycle stability. Under optical control, it shows a shortened optical response time (the coloring/bleaching is 70.3/158.9 s), excellent coloration efficiency (58.2 cm2/C), better area capacitance (51.1 mF/cm2), and excellent photoelectric conversion efficiency.

Substance discrimination imaging derived from switchable soft and hard x‐ray sensing in direct x‐ray detector

AbstractSubstance discrimination beyond the shape feature is urgently desired for x‐ray imaging for enhancing target identification. With two x‐ray sources or stacked two detectors, the two‐energy‐channel x‐ray detection can discriminate substance density by normalizing the target thickness. Nevertheless, the artifacts, high radiation dose and difficulty in image alignment due to two sources or two detectors impede their widespread application. In this work, we report a single direct x‐ray detector with MAPbI3/MAPbBr3 heterojunction for switchable soft x‐ray (<20 keV) and hard x‐ray (>20 keV) detection under one x‐ray source. Systematic characterizations confirm soft and hard x‐ray deposit their energy in MAPbI3 and MAPbBr3 layer, respectively, while working voltages can control the collection of generated charge carriers in each layer for selective soft/hard x‐ray detection. The switching rate between soft and hard x‐ray detection mode reaches 100 Hz. Moreover, the detector possesses a moderate performance with ~50 nGy s−1 in limit‐of‐detection, ~8000 μC Gy−1 cm−2 in sensitivity and ~7 lp/mm in imaging resolution. By defining the attenuation coefficient ratio (𝜇L/𝜇H) as substance label, we effectively mitigate the influence of target thickness and successfully discriminate substances in the acquired x‐ray images.image

Multilayer network analysis reveals instability of brain dynamics in untreated first-episode schizophrenia.

Although aberrant static functional brain network activity has been reported in schizophrenia, little is known about how the dynamics of neural function are altered in first-episode schizophrenia and are modulated by antipsychotic treatment. The baseline resting-state functional magnetic resonance imaging data were acquired from 122 first-episode drug-naïve schizophrenia patients and 128 healthy controls (HCs), and 44 patients were rescanned after 1-year of antipsychotic treatment. Multilayer network analysis was applied to calculate the network switching rates between brain states. Compared to HCs, schizophrenia patients at baseline showed significantly increased network switching rates. This effect was observed mainly in the sensorimotor (SMN) and dorsal attention networks (DAN), and in temporal and parietal regions at the nodal level. Switching rates were reduced after 1-year of antipsychotic treatment at the global level and in DAN. Switching rates at baseline at the global level and in the inferior parietal lobule were correlated with the treatment-related reduction of negative symptoms. These findings suggest that instability of functional network activity plays an important role in the pathophysiology of acute psychosis in early-stage schizophrenia. The normalization of network stability after antipsychotic medication suggests that this effect may represent a systems-level mechanism for their therapeutic efficacy.

A compact solid-state high repetition rate trigger based on a spiral generator.

The trigger generator made with a spiral generator (SG) has the advantages of light weight, compact structure, and low cost and has promising applications in the pulsed power field. This paper introduces a compact solid-state high-voltage pulse trigger system based on an improved SG, which has improved repetition rate and lowered the demands for semiconductor switches' maximum current and current rise rate when compared with previous studies. The improvement is achieved by winding outward an additional layer of the passive layer and low-voltage metal strip, which realizes a significant reduction of the peak current and current rise rate of the discharge switch. The final dimension of the trigger is 25 × 10 × 10cm3, excluding the power supply. An experiment carried out in single shot mode shows that the peak value of the output pulse can reach 50kV with a leading edge of 57ns. Repetitive experiments were carried out up to 1kHz, with the peak voltage of the output pulse being 30.5kV, the leading edge being 48ns, and the jitter being 0.84ns. Finally, the generator is used to trigger a gas switch, and it works stably and reliably.

Study on electro-optical dual-control color-changing and energy-storage device based on Mo-WO3 and Al-TiO2 thin film electrode

Under optical and electrical control, a multifunctional electro-optical dual-control color-changing and energy-storage device not only realizes quick color conversion, but also achieves good storage performance. In this work, Mo doped WO3 (Mo-WO3) films were synthesized through one-step hydrothermal method and N719/Al doped TiO2 (N719/Al-TiO2) films were synthesized by hydrothermal and dip-dyeing method. Eventually, choosing Mo-WO3 as cathode and N719/Al-TiO2 film as anode, a multifunctional electro-optical dual-control Mo-WO3@N719/Al-TiO2 color-changing and energy-storage device was constructed. Under electrical control, the device shows excellent coloration efficiency (73.99 cm2/C), fast color switching rate (coloring/ bleaching time is 3.6 s/1.4 s), obviously improved area capacitance (about 82.6 mF/cm2) and excellent cycle stability. Under optical control, the device also shows shortened response time (coloring/ bleaching is 64.3 s/143.4 s), outstanding coloration efficiency (70.49 cm2/C), better area capacitance (about 58.6 mF/cm2) and excellent photoelectric conversion efficiency (10.56 %).

Utilising an in silico model to predict outcomes in senescence-driven acute liver injury

Currently liver transplantation is the only treatment option for liver disease, but organ availability cannot meet patient demand. Alternative regenerative therapies, including cell transplantation, aim to modulate the injured microenvironment from inflammation and scarring towards regeneration. The complexity of the liver injury response makes it challenging to identify suitable therapeutic targets when relying on experimental approaches alone. Therefore, we adopted a combined in vivo-in silico approach and developed an ordinary differential equation model of acute liver disease able to predict the host response to injury and potential interventions. The Mdm2fl/fl mouse model of senescence-driven liver injury was used to generate a quantitative dynamic characterisation of the key cellular players (macrophages, endothelial cells, myofibroblasts) and extra cellular matrix involved in liver injury. This was qualitatively captured by the mathematical model. The mathematical model was then used to predict injury outcomes in response to milder and more severe levels of senescence-induced liver injury and validated with experimental in vivo data. In silico experiments using the validated model were then performed to interrogate potential approaches to enhance regeneration. These predicted that increasing the rate of macrophage phenotypic switch or increasing the number of pro-regenerative macrophages in the system will accelerate the rate of senescent cell clearance and resolution. These results showcase the potential benefits of mechanistic mathematical modelling for capturing the dynamics of complex biological systems and identifying therapeutic interventions that may enhance our understanding of injury-repair mechanisms and reduce translational bottlenecks.

Analysis of SF6 and CF4 consumption for refueling high-voltage switching equipment

The article describes to eliminate possible errors in the supply of cylinders with sulfur hexafluoride and cylinders with carbon tetrafluoride to high-voltage substations for refueling switching devices such as high-voltage switches, voltage transformers, etc. Conduct an analysis of possible erroneous supplies of the two above-mentioned gases at the substation. Make an analysis of possible residuals (or shortfalls) of gas cylinders after refilling. Make an assumption about the reasons for the appearance of possible residues. Give recommendations for overcoming possible problems. Make the appropriate calculations. Propose a formula (table) for recalculating the consumption of both types of gases. Make a table for calculating the actual values of the number of supplied cylinders, related to the discreteness of the volumes of the cylinders and the switching devices themselves. Draw appropriate conclusions and make recommendations. To achieve this goal, a method was used to calculate the state of an ideal gas using software for working with spreadsheets. The article reflects the relevance of the topic and discusses the features of refueling high-voltage SF6 equipment in various climatic conditions (below minus 40-49°F). An analysis of typical ratings of high-voltage switches used at highvoltage substations was carried out. A graph is presented for converting the molar fraction (contributing to pressure) of gases into the mass fraction. A sample calculation of the number of cylinders is presented for two commonly encountered volumes of switching devices and fortyliter gas cylinders for several standard cylinder filling ratios. Presumptive conclusions are presented regarding the assessment of real errors when sending gas cylinders for refilling switching devices. The article offers an understanding of the sequence of problems associated with incorrect calculations and a complete methodology for calculating the correct volumes (mass) of gas depending on the actual types of devices used, depending on the volume of supplies pieces of equipment.

Low Versus Standard Intensity Heparin Protocols in Adults Maintained on Extracorporeal Membrane Oxygenation: A Retrospective Cohort Study

Background: Patients maintained on extracorporeal membrane oxygenation (ECMO) often require systemic anticoagulation to prevent circuit clotting and systemic thromboembolic complications. The optimal intensity of anticoagulation to balance the risk of bleeding and prevention of thrombotic complications in this patient population is not well described. Objective: To compare bleeding events in patients on ECMO anticoagulated with standard vs low intensity heparin protocols. Methods: This single-center, retrospective cohort study included adult patients on VA- or VV-ECMO and anticoagulated with low or standard intensity heparin protocols. The primary outcome was the incidence of major bleeding; secondary outcomes included the incidence of minor bleeding, thrombotic complications, heparin-induced thrombocytopenia, in-hospital mortality, time in therapeutic range, anti-Xa correlation with aPTT, intensive care unit and hospital lengths of stay, oxygenator exchanges, and rate of protocol switching. Results: A total of 27 patients (14 low intensity, 13 standard intensity) were included. There were six major bleeding events in the low intensity group and four in the standard intensity group ( P = 0.69); there were four minor bleeding events in the low intensity group and five in the standard intensity group ( P = 0.69). Seven patients in the standard intensity group switched protocols; zero patients in the low intensity group switched protocols ( P = 0.002). There were no differences in any other outcomes. Conclusions: There was no difference in the incidence of any bleeding or thrombotic events when using a low vs standard intensity heparin protocol in patients on ECMO. A low intensity heparin strategy for patients on ECMO may be feasible and safe.

Neighbors affect vocal behavior of tropical wrens: a multispeaker density-manipulation experiment.

For territorial animals, the behavior of conspecific neighbors sets the social context of communication. Despite numerous investigations of vocalizations related to territory defense and mate attraction, the effect of neighbor density on animal vocal behavior has received little attention, particularly in tropical animals and animals where both sexes produce complex acoustic signals. In this study, we used an innovative multispeaker playback experiment to manipulate the apparent density of neighbors in rufous-and-white wrens, Thryophilus rufalbus, living in Costa Rica's tropical dry forest. In this tropical songbird, both males and females defend year-round territories and sing complex, learned songs for territory defense. We recorded the singing behavior of 24 subjects (12 pairs), and then we used an array of 6 loudspeakers to simulate the presence of 6 new territorial neighbors (3 simulated pairs) outside each subject pair's breeding territory. The stimuli persisted for 3 consecutive days, with both male and female songs broadcast at a natural rate from dawn to dusk. We found that the mean male song rate increased by almost 50% in response to the simulated increase in local density. Females showed less frequent song-type switching rates following the simulated increase in local density, although it was a marginal increase. These findings reveal that male and female songbirds' vocal behavior varies with the local density of territorial neighbors. We conclude that birds are sensitive to acoustic signals of conspecific density arising from sounds beyond their territory boundaries, and that they use this public information to guide their vocal behavior.

Psoriasis treatment and biologic switching: The association with clinical characteristics and laboratory biomarkers over a 13-year retrospective study.

The advent of biologics has greatly improved patient outcomes, yet some patients are compelled to switch therapies. Predicting these therapeutic failures is important; however, the factors associated with switching biologics have not been fully explored. This study examined patterns and determinants of biologics switching in psoriasis treatment retrospectively over 13 years. We focused on the association between clinical characteristics, basal laboratory data, and frequency of biologics switching. The findings revealed that elevated Psoriasis Area Severity Index scores and the presence of arthritis were observed in patients who experienced two or more treatment switches compared with those without treatment switches. Moreover, neutrophil to lymphocyte ratio was associated with higher biologics switching rates, indicating that systemic inflammation significantly impacts treatment adherence. A treatment approach, taking into account both the clinical presentation and inflammatory biomarkers, may be important for optimizing patient management in psoriasis.

Photonic generation and programmable switching of variable-band chirped waveforms with immunity to power fading.

A photonic approach for generating and programmable switching variable-band chirped waveforms by using a dual-parallel Mach-Zehnder modulator (DPMZM) is proposed and experimentally demonstrated. By coupling binary switching codes with the baseband chirped signal and applying them into the RF input port of DPMZM, the variable-band chirped waveforms can be generated and fast switched. The switching speed is consistent with the input code bit rate. Moreover, by properly adjusting the bias voltages, the generated signals can be anti-dispersion transmitted over different distances. Full experimental verification on the generation and programmable switching of the chirped waveforms centered at 2.1, 6.3, and 8.4 GHz or 1.5, 4.5, and 6 GHz over 10 or 20 km standard single-mode fibers with 4 or 100 Mbps switching rates are successfully carried out. The proposed approach features compact architecture, programmable switching capability and immunity to power fading, which are significant in distributed multifunction radar networks with optical fiber-based transmission.

Resonant-force-induced symmetry breaking in a quantum parametric oscillator

A parametrically modulated oscillator has two opposite-phase vibrational states at half the modulation frequency. An extra force at the vibration frequency breaks the symmetry of the states. The effect can be extremely strong due to the interplay between the force and the quantum fluctuations resulting from the coupling of the oscillator to a thermal bath. The force changes the rates of the fluctuation-induced walk over the quantum states of the oscillator. If the number of the states is large, then the effect accumulates to an exponentially large factor in the rate of switching between the vibrational states. We find the factor and analyze it in the limiting cases, including the prebifurcation regime where the system is close but not too close to the bifurcation point.

Linker Conformation Controls Oxidation Potentials and Electrochromism in Highly Stable Zr-Based Metal-Organic Frameworks.

The development of tailor-made electrochromic (EC) materials requires a large variety of available substances with properties that precisely match the task. Since the inception of electrochromic metal-organic frameworks (MOFs), the field relies only on a limited set of building blocks, providing the desired electrochromic effect. Herein, we demonstrate for the first time the implementation of a Piccard-type system (N,N,N',N'-benzidinetetrabenzoate) into Zr-MOFs to obtain electrochromic materials. With fast switching rates, high contrast ratio, long-life stability, and exceptional chemical and physical stability, the novel material is on par with inorganic EC material. The new EC system exhibits an ultrahigh contrast from the bleaching state, with transmittance in the visible region >53%, to the colored state with a transmittance of ca. 3%. The 5 μm thick film attained up to 90% of the coloring in 12.5 s and exhibited high electrochemical reversibility. Moreover, the conformational lability of the electrochromic ligand chosen is locked via the topology design of the framework, which is not attainable in the solution. Locked conformations of the redox active linker in distinct polymorphous frameworks (DUT-65 and DUT-66) feature different redox characteristics and opens the door to the overarching control of the oxidation pathway in the Piccard-type systems.

Singular limit of a chemotaxis model with indirect signal production and phenotype switching

Abstract Convergence of solutions to a partially diffusive chemotaxis system with indirect signal production and phenotype switching is shown in a two-dimensional setting when the switching rate increases to infinity, thereby providing a rigorous justification of formal computations performed in the literature. The expected limit system being the classical parabolic–parabolic Keller–Segel system, the obtained convergence is restricted to a finite time interval for general initial conditions but valid for arbitrary bounded time intervals when the mass of the initial condition is appropriately small. Furthermore, if the solution to the limit system blows up in finite time, then neither of the two phenotypes in the partially diffusive system can be uniformly bounded with respect to the L 2-norm beyond that time.

Manufacturer-sponsored drug coupon use and drug-switching behavior among patients with type 2 diabetes.

Patients often use manufacturer-sponsored coupons to reduce their out-of-pocket spending. However, little is known whether coupon use is associated with medication-switching behaviors. To examine if using a manufacturer-sponsored coupon to initiate a medication is associated with patterns of medication-switching behaviors among patients with type 2 diabetes. Using IQVIA's retail pharmacy claims data from October 2017 to September 2019, we analyzed commercially insured patients with type 2 diabetes who had newly started taking the following noninsulin diabetes drugs: generic metformin (nearly no coupon use), Sodium-glucose Cotransporter-2 (SGLT2) Inhibitors (SGLT2, high coupon use), and dipeptidyl peptidase IV inhibitors (DPP-IV inhibitors, moderate coupon use). We assessed if drug-switching behaviors, defined as no switching, switching to a same-class drug, or switching to a drug in a different class, differed among patients who did and did not use coupons to initiate treatments. We performed multinomial logistic regression to estimate the probability of each switching type associated with patients' initial coupon use. Among 9,781 patients in our sample, 83.7% of them initiated treatments with metformin, 8.2% with SGLT2, and 8.1% with DPP-IV inhibitors. The overall switching rate was the lowest for generic metformin (40%) than brand-name drugs (56%-57%). Among the brand-name drug users, patients who used a coupon to initiate these drugs were less likely to switch to any drug compared with patients without coupon use (SGLT2 = -18% [95% CI = -24% to -13%]; DPP-IV inhibitors = -9% [-16% to -2%]). These patients were also less likely to switch to drugs in other competing classes (SGLT2 = -16% [95% CI = -22% to -10%]; DPP-IV inhibitors = -9% [-16% to -2%]). Patients who started their treatment with generic metformin had the lowest rate of drug switching. Using coupons to initiate brand-name drugs in classes with prevalent coupons was associated with reduced medication switching to other class drugs.

Exposure to Valsartan Products Containing Nitrosamine Impurities in the United States, Canada, and Denmark.

Following the mass recall of valsartan products with nitrosamine impurities in July 2018, the number of patients exposed to these products, the duration of exposure, and the potential for cancer remains unknown. Therefore, we assessed the extent and duration of use of valsartan products with a nitrosamine impurity in the United States, Canada, and Denmark. We conducted a retrospective cohort study using administrative healthcare data from the US FDA Sentinel System, four Canadian provinces that contribute to the Canadian Network for Observational Drug Effect Studies (CNODES), and the Danish National Prescription Registry. Patients, 18 years and older between May 2012 and December 2020 with a valsartan dispensing were identified in each database. Patients were followed from the date of valsartan dispensing until discontinuation. We defined four valsartan exposure categories based on nitrosamine impurity status; recalled generic products with confirmed NDMA/NDEA levels (recalled-tested); recalled generic products that were not tested (recalled); non-recalled generic and non-recalled branded products. In Denmark, the recalled-tested category was not included due to absence of testing data. The proportion and duration of use of valsartan episodes stratified by nitrosamine-impurity status was calculated. We identified 3.3 and 2.8 million (United States) and 51.3 and 229 thousand (Canada) recalled-tested and recalled valsartan exposures. In Denmark, where valsartan exposure was generally low, there were 10 747 recalled exposures. Immediately after the recall notices were issued, there was increased rates of switching to a non-valsartan ARB. The mean duration of use of the recalled-tested products was 167 (±223.1) and 146 (±255.8) days in the United States and Canada respectively. For the recalled products, mean cumulative duration of use was 178 (±249.6), 269 (±397.3) and 166 (±251.0) days in the United States, Canada, and Denmark, respectively. In this cohort study, despite widespread use of recalled generic valsartan between 2012 and 2018, the duration of use was relatively short and probably did not pose an elevated risk of nitrosamine-induced cancer. However, since products with nitrosamine impurity could have been on the market over a 6-year period, patients exposed to these products for longer durations could have a potentially different risk of cancer.

Advanced PSO Algorithms Development with Combined lbest and gbest Neighborhood Topologies

Abstract This paper introduces an innovative approach integrating global best (gbest) and local best (lbest) PSO communication topologies. The algorithm initiates with lbest and seamlessly transitions to gbest, with the switching rate controlled by the parameter “a”. Rational values of “a” is determined through numerical experiments. A comparative methodology employing two estimation criteria is used to showcase the improved performance of the modified PSO-based algorithms. Furthermore, the efficacy of this approach is demonstrated in addressing two optimal control problems within dynamical systems. Results highlight the modified algorithms’ superiority in terms of the total number of successful runs and statistical indicators. Consequently, these advanced algorithms prove effective for applications such as artificial neural network training, controller gains determination, and similar problem domains.

Comparison of Surgery and Stent Application in the Treatment of Tracheal Stenosis

Introduction Tracheal stenosis is a pathology that is gradually increasing and requires intervention. Surgical treatment has been used as the gold standard for years, but it is difficult to decide on surgery in patients with comorbidities and high surgical risk. We aimed to evaluate the data of both treatment methods applied in our center. Materials And Methods Our study was designed as retrospective and observational. The data of 61 patients who underwent resection & reconstruction or stent due to tracheal stenosis in our center between May 2002 and May 2019 were analyzed. 54 patients who met the inclusion criteria were included in the study. Results 44 patients who met the inclusion criteria were studied. Both treatment methods were found to be effective in reducing the stenosis and regressing the complaints. The average age in the stent group was higher than in the surgery group. As the intensive care period in the intubated state increases; Severe stenosis and deterioration of cartilage integrity increased. An increase in antibiotic switching rates was observed in steroid users. Post-procedure complication rate was 22.5% in the surgery group, 53.5% in the stent group. The satisfaction score of the surgery group was higher than the stent group. Conclusion Both treatment methods are effective in improving respiratory functions and quality of life. The lesion was located higher in the surgical group and was longer in the stent group. Hospitalization times were longer in patients with severe stenosis and antibiotic changes were more frequent in patients using steroids. No statistically significant difference was found.
