Abstract

Fe2O3/ZnO fiber membranes with a high specific surface area and broadened UV-Vis absorption were successfully fabricated by electrospinning followed by calcination. The diameters of Fe2O3/ZnO fibers are approximately 150 nm, and the specific surface areas of Fe2O3/ZnO fiber membranes are around 29 m2/g. XRD, SEM, and XPS results confirm the formation of a heterojunction between hexagonal ZnO and hematite α-Fe2O3. Compared with pure ZnO fiber membranes, the UV-Vis absorptions of the Fe2O3/ZnO fiber membranes are extended, and transient photocurrent intensities are significantly increased from 0.65 mA/cm2 to 0.86 mA/cm2. The free radical capture experiments further reveal the generation of abundant •OH radicals, which play a crucial role in enhancing the photocatalytic performance of these Fe2O3/ZnO fiber membranes. Optimization studies have determined that the most effective molar ratio of Fe to Zn in the Fe2O3/ZnO heterojunction is 8 mol%, resulting in a 45% increase in photocatalytic degradation efficiency for MB. In addition to this enhanced photocatalytic efficacy, the Fe2O3/ZnO fiber membranes also demonstrate exceptional cycling stability, highlighting their significant potential for application in the photocatalytic treatment of dye wastewater.

Abstract

Objectives: To assess the relationship between the Child Opportunity Index (COI), a validated measure that uses 29 indicators of social determinants of health linked to the US Census, and pediatric supraventricular tachycardia (SVT) management and outcomes, specifically looking at utilization of ablation.
Study Design: A retrospective, single-center study was performed evaluating pediatric SVT patients from January 2018-July 2023. Patients diagnosed at < 5 years old, with pre-excitation, and with hemodynamically significant congenital heart disease were excluded. Characteristics were compared among low, moderate, and high COI categories using Kruskal-Wallis tests for continuous variables, and chi-square or Fisher’s exact tests for categorical variables. Logistic regression and log-normal regression models were used to assess the relationship between COI category and primary outcomes of interest among SVT patients.
Results: A cohort of 306 patients met inclusion criteria. 45% had a high COI, 29% a moderate COI, and 26% a low COI. The odds of having one or more hospital admissions were 3.88 times greater for the low COI patients compared to high COI patients (95% CI: 1.39-10.8, p = 0.010). COI was not found to be associated with any other primary outcomes of interest, including utilization of ablation.
Conclusions: Lower COI was associated with greater odds of admission in SVT patients but did not differ in rates of ablation or outcomes. This suggests social factors may affect resource utilization while having limited impact on treatments like ablations.

Published: November 2024

Abstract

Background and Objectives The flexible nasopharyngolaryngoscopy (F-NPLS) is a routine office procedure. We compared two trajectories of intranasal scope negotiation used for F-NPLS and assessed patients comfort and performers satisfaction. Methods This is prospective, randomized, parallel group controlled study. Patients undergoing F-NPLS for evaluation of upper airway were enrolled and randomized into two study groups. Group A patients underwent intranasal scope negotiation trajectory “below middle turbinate”; for group B patients the trajectory of “along the inferior turbinate” was used. The primary outcome evaluated was successful unhindered scope negotiation in first attempt. Patient perceived pain, event of mucosal trauma and bleeding, episode and need of repetition of scopy were evaluated as secondary outcome. Results One hundred and eleven patients were randomized into group A (n = 53) and group B (n = 58). Baseline characteristics age, gender were similar in both the groups. Both groups did not show statistical difference with respect to primary outcome. (Group A: 52.8% Vs Group B: 55.2%, p = 0.8) The F-NPLS without episode of mucosal trauma was significantly higher in group B (Group A: 56.9% Vs Group B:35.9%, p = 0.004). The mucosal ecchymosis was commonly encountered finding in group A (Group A: 41.5% Vs Group B:13.8%, p = 0.03) whereas, nasal bleeding observed frequently in group B though statistically insignificant. (Group A: 29.3% Vs Group B:22.6% p = 0.42) Conclusion The present study showed that there is no difference in successful unhindered F-NPLS using either of the trajectory. However, patient experienced moderate to severe pain during repeat scopy as compared to the F-NPLS in first attempt itself.

Published: November 2024

Abstract

Background: Hypertension (HTN) and diabetes mellitus (DM) are associated with cognitive impairment and dementia. Antihypertensive treatment may improve cognitive functioning. Elevated blood glucose levels can increase the risk of dementia even in non-DM. Both HTN and DM may contribute to the development of Alzheimer’s disease.
Aims: The aim of this study was to assess the influence of vascular risk factors on cognition.
Methods: The study was conducted in the south of Poland among rural population over 65 years of age. 85 patients qualified into the study were divided into groups according to the presence of HTN (n=18), DM (n=7), or both (n=40). Control group was also formed (n=20). Biochemical tests, neurological scales assessment and ultrasound examinations were conducted.
Results: The median score for the M-ACE scale was 3 points lower when HTN and DM coexisted, compared to the diagnosis of DM or HTN solely (25 points and 28 points respectively). Considering MMSE scale the results were comparable. The higher number of years of education correlated with better M-ACE result (median value of years of education 11 for the >25 points M-ACE results and 9 for patients with suspected dementia (<22 M-ACE points)
Conclusions: The coexistence of DM and HTN caused the most profound decline in cognitive functioning of patients. Moreover, the higher number of years of education was a protective factor against the development of dementia in old age. Cholesterol and uric acid roles in cognitive decline are still debatable.
Enhancing Patient Education With AI:A Readability Analysis of AI-Generated Versus American Academy of Ophthalmology Online Patient Education Materials
Authors: Kufta Allison , Djalilian Ali 
Published: November 2024

Abstract

Purpose: This study aims to compare the readability of patient education materials (PEMs) written by the American Academy of Ophthalmology (AAO) with those generated by large language models (LLMs), including ChatGPT-4o, Microsoft Copilot, and Meta-Llama-3.1-70B-Instruct.
Methods: LLMs were prompted to generate PEMs for 15 common diagnoses relating to cornea and anterior chamber, which was followed by a prompt to reword the content at a 6th-grade reading level. The readability of these materials was evaluated using nine different readability analysis python libraries and compared to existing PEMs found on the AAO website.
Results: For all 15 topics, ChatGPT, Copilot, and Llama successfully generated PEMs, though all exceeded the recommended 6th-grade reading level. While unprompted ChatGPT, Copilot, and Llama outputs were 10.8, 12.2, and 13.2, respectively, prompting significantly improving readability to 8.3 for ChatGPT, 11.2 for Copilot, and 9.3 for Llama (p < 0.001). While readability improved, AI-generated PEMs were on average, not statistically easier to read than AAO PEMs, which averaged an 8.0 Flesch-Kincaid grade level.
Conclusions: Prompted AI chatbots can generate PEMs with improved readability, nearing the level of AAO materials. However, most outputs remain above the recommended 6th-grade reading level, and the brevity of Copilot's responses raises concerns about content quality. By creating a blueprint, AI chatbots show promise as tools for ophthalmologists to increase the availability of accessible PEMs in ophthalmology.

Authors: Chen ZhengWei , Wang Gaoxiang , Xia Tianyang , Shao Wei , Liu Changqing , Zhang Weiguo , Wang Fangqin , Xie Mingran 
Published: November 2024

Abstract

Objective
This study evaluates the prognostic value of preoperative inflammatory markers—Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte Ratio (PLR), Systemic Immune-Inflammation Index (SII), and Fibrinogen-to-Prealbumin Ratio (FPR)—in patients with resectable esophageal squamous cell carcinoma (ESCC). A survival prognostic model integrating these markers with TNM staging was developed and validated.
Methods
Clinical data from 224 ESCC patients who underwent surgical resection between January 2017 and December 2017 at the First Affiliated Hospital of the University of Science and Technology of China were retrospectively analyzed as a training set, and data from 87 patients at Tongling People's Hospital (January 2018 to September 2019) served as the validation set. ROC analysis determined optimal cut-off values for NLR, PLR, SII, and FPR. Survival was analyzed using the Kaplan-Meier method, and prognostic factors were identified through Cox regression. A nomogram was constructed using R software to predict overall survival (OS) and disease-free survival (DFS). Model performance was assessed via ROC, calibration curves, and decision curve analysis (DCA).
Results
The optimal cut-off values for NLR, PLR, SII, and FPR were 2.70, 140.34, 360.73, and 0.015, respectively. Higher NLR, PLR, and FPR levels were associated with significantly poorer 5-year OS and DFS (all p < 0.01), while higher SII levels were associated with improved outcomes (p = 0.008 for OS, p = 0.013 for DFS). Multivariate Cox analysis identified age, T stage, N stage, differentiation, and NLR as independent prognostic factors. The nomogram demonstrated strong predictive accuracy, with ROC AUCs of 0.966 (3-year OS), 0.907 (5-year OS), 0.960 (3-year DFS), and 0.919 (5-year DFS). Calibration curves confirmed model reliability, and DCA indicated high clinical utility.
Conclusions
Preoperative NLR, PLR, SII, and FPR are significant predictors of ESCC prognosis, with NLR serving as an independent marker. The nomogram based on inflammatory markers and clinicopathological factors accurately predicts patient outcomes, aiding preoperative decision-making and postoperative management.

Authors: TEKE Mehmet Turhan , ÖZYURTSEVEN Betül TAŞ 
Published: November 2024

Abstract

Objectives: In our study, kinesio taping was used to reduce pain, edema and trismus more rapidly following extraction of impacted mandibular third molars. It was investigated whether kinesio taping affects the blood flow in the extraction site and the rate of edema drainage, and its potential to increase patient comfort in the postoperative period was evaluated.
Materials and Methods: 87 patients who underwent surgical extraction of impacted mandibular third molars were included in our parallel-arm randomized clinical study. While patients in the control group were only observed, a fan-shaped kinesio tape application was applied between the clavicle and tragus in the kinesio tape group to provide lymphatic drainage. Blood flow measurements were taken with a laser Doppler flowmeter device at four points identified in the head and neck region where lymphatic channels drain: preoperatively, immediately after the operation, and on the 2nd, 4th and 7th days post-operation. Additionally, pain symptoms, maximum mouth opening, and edema measurements were evaluated on the 2nd, 4th and 7th days of post-operation.
Results: The kinesio tape group consists of 22 females and 21 males, with a mean age of 23.5 ± 4.02 years, while the control group consists of 22 females and 22 males, with a mean age of 23.3 ± 3.19 years. In the kinesio tape group, higher blood flow was measured, with lower pain on the 2nd day and reduced edema on the 4th day compared to the control group. It was observed that mouth opening was regained more rapidly from the 2nd day onwards.
Conclusions: Our study shows that the application of kinesio tape reduces postoperative complications and improves quality of life. Kinesio tape application, which stands out with its atraumatic and ease of application, has been a supportive method which we believe to be useful in the management of morbidity following oral surgery applications.

Published: November 2024

Abstract

Background
Mesenchymal stem cells (MSCs) and their exosomes, particularly adipose-derived stem cell exosomes (ADSC-Exs), have shown promise in treating secondary lymphedema (SLE), a condition characterized by fibrosis driven by the TGFβ-Smad signaling pathway. While ADSCs and ADSC-Exs have demonstrated antifibrotic effects, it is not yet clear whether these benefits stem from their ability to regulate this pathway. This study aimed to clarify the role of ADSCs and ADSC-Exs in reducing fibrosis in SLE by modulating the TGFβ-Smad pathway.
Methods
We established a secondary lymphedema model in C57BL/6 mice through surgical excision and localized radiation. Tissue staining was used to assess fibrosis progression at key time points, identifying the peak fibrosis stage. ADSCs and ADSC-Exs were injected into the affected areas to test their therapeutic effects, while TGFβ1 inhibitors were used as controls to block the TGFβ-Smad signaling pathway. This study compared the effects of ADSCs, ADSC-Exs, and the inhibitors on lymphedema and fibrosis markers, with a focus on their influence on the TGFβ-Smad pathway.
Results
Fibrosis in the SLE model peaked between the 4th and 5th weeks. Both ADSCs, ADSC-Exs, and the TGFβ inhibitor EW-7197 reduced edema and fibrosis, with ADSC-Exs having the most significant effect on skin fibrosis. This was evident by decreased levels of TGFβ1, Smad2/3, and phosphorylated Smad2/3, along with increased Smad7 levels, indicating that ADSC-Exs effectively regulate the TGFβ-Smad pathway to reduce fibrosis.
Conclusions
Our findings demonstrate that ADSCs and ADSC-Exs significantly alleviate edema and fibrosis in a secondary lymphedema mouse model. This therapeutic effect is largely mediated through the regulation of the TGFβ-Smad pathway, suggesting a promising approach for treating fibrosis in SLE.

Authors: Hoseini Farnaz , Notash Anaram Yaghoobi 
Published: November 2024

Abstract

Putting captions on images is an important phase in image processing and machine vision which divides an image into different regions. In the related captioning operation, similar attributes are extracted from each region and a single caption is opted for the title of the input for the relevant image. In the developed world, due to the considerable volume of images that are available on the Internet, it is complicated to choose a suitable method for captioning images automatically and determining concepts correctly. In this study, a method based on a Bidirectional LSTM neural network with 14 layers is used for automatic captioning. The dataset is trained on ImageNet by MobileNet architecture. Due to the high volume of the data set consequently with the huge calculations that are required for captioning, MobileNet architecture has been applied to decrease the computational load and to boost the performance of the proposed method. in this study, the data set is flickr8k with a volume of data of more than 1.04 GB which was selected as one of the challenging data sets for captioning images through the Kaggle site. The proposed method is implemented with Python language by artificial intelligence package TensorFlow and Cross on Google Colab. The proposed Bidirectional LSTM neural network has been compared with five other models based on the LSTM neural network. So, the results of these comparisons have been evaluated for Precision, Accuracy, Recall, F score, and Loss Function. According to the hardware's limitations and the huge volume of calculations, the proposed model was able to show convincing performance compared to other models. The obtained results with an accuracy of 75.90% indicate the improvement of the accuracy as well as the reduction of the cost in the captioning process for the proposed model.

Published: November 2024

Abstract

Background
Second victim experiences of nurses are a critical issue in healthcare. In addition to causing psychological and emotional distress to nurses, second-victim experiences adversely affect organizational performance and overall patient safety.
Purpose
This study aimed to identify the effects of the perceived just culture of medical institutions on the second victim experiences of nurses after patient safety incidents.
Methods
This was a cross-sectional correlational study. Data were collected from 183 clinical nurses in tertiary general hospitals between December 28, 2022 and January 14, 2023 using an online self-report questionnaire. Data were analyzed using SPSS WIN 23.0 and AMOS 23.0 programs.
Results
The hypothesized model was found to be statistically fit (normed χ2 /df = 2.53; root mean square error of approximation = .09; comparative fit index = .99; Tucker-Lewis index = .97; normed fit index = .99). Eight hypothesized pathways were tested, of which five direct effects and three indirect effect pathways were statistically significant. Just culture had a significant effect on second victim distress (β = -0.29, p = .001) and demand for support (β = -0.65, p = .001). Second victim distress had a significant effect on demand for support (β = 0.14, p = .025) and negative work-related outcomes (β = 0.66, p = .001). Demand for support had a significant effect on negative work-related outcomes (β = 0.18, p = .010).
Conclusions
This study demonstrates that a just culture in medical institutions can ameliorate second victim experiences of nurses involved in patient safety incidents. Implementing systemic interventions to establish a just culture in medical institutions is a key imperative to mitigate second victim experiences and improve organizational performance.

Abstract

Study Design: Retrospective Cohort Study
Objectives: Chondrosarcoma of mobile spine is a rare aggressive malignant tumor and postsurgical local recurrence rates remain high. En bloc resection is currently the preferred treatment. Resection that achieves non-intralesional removal of the tumor may enable more complete removal of tumor tissue but significantly increases the complexity and risk of surgery and results in more postoperative complications. We sought to compare surgical outcomes, complications, and prognoses between patients who underwent en bloc resection with and without intralesional removal of the tumor.
Methods: We reviewed 56 patients with spinal chondrosarcoma who underwent en bloc tumor resection and reconstructive surgery at our center between 2000 and 2024 with a minimum postoperative follow-up of 1 year. We collected and analyzed data regarding surgical procedures, complication characteristics, and local tumor control and recurrence.
Results: We included 56 patients. Of these, 36 patients underwent the first surgery, and 20 experienced recurrences. All patients underwent en bloc tumor resection; 36 and 20 underwent intralesional and non-intralesional resections, respectively. We recorded 83 complications; the incidence and the number of major complications were significantly higher in the non-intralesional surgery group. Thirty patients experienced tumor recurrence and 26 patients died. Non-intralesional en bloc resection and conventional-type chondrosarcoma were predictive factors for reduced long-term postoperative recurrence and mortality risk.
Conclusions: Non-intralesional resection carries higher risks and is associated with a greater number of perioperative complications, but reduces the risk of local tumor recurrence and prolongs recurrence-free survival and overall survival, providing patients with better prognoses.

Abstract

Background
The evaluation of Hand Grip Strenght (HGS) is relevant for the early detection of muscle weakness. It may be an early indicator of juvenile sarcopenia and other alterations associated with neuromuscular disorders.
Objective
a) to compare hand grip strength (HGS) with other regional studies and b) to propose reference values of HGS by age, sex in children and adolescents living in a moderate altitude region of Peru.
Methodology:
A cross-sectional study was designed in school children and adolescents living in a moderate altitude region of Peru (2320 meters above sea level). The sample selection was non-probabilistic (accidental), considering 1058 schoolchildren (557 boys and 501 girls) with an age range of 6 to 17 years. These schoolchildren came from public schools. Weight, height and Body Mass Index (BMI) were assessed. HGS of both hands (right, left and both hands) was evaluated. The p50th percentile was used to compare discrepancies with studies from Chile, Colombia and Peru.
Results
The median values (p50) of both hands show a linear increase with advancing age. It is expected that HGS tends to increase as children get older. The maximum HGS of both hands occurred in males at 17 years of age (38.87kg/f). While in females it was at 15–16 years (23.56kg/f). Discrepancies in HGS were observed when comparing the 50th percentile (P50) of schoolchildren living at moderate altitude in Peru with regional studies carried out in Chile, Colombia and Peru. HGS percentiles by age and sex were developed for the left, right and both hands (P3, P5, P15, P25, P50, P75, P85, P90, P95 and P97).
Conclusion
The study demonstrated discrepancies in HGS between schoolchildren living in a moderate altitude region of Peru and neighboring regions. This allowed us to propose percentiles to evaluate HGS by age and sex. The results suggest its use in educational and clinical contexts.
