Published: December 2024

Abstract

Obstructive sleep apnea (OSA) is a prevalent condition that frequently goes undiagnosed. NoSAS Score provides a straightforward approach for rapid and accurate OSA screening, although it requires measuring neck circumference (NC). We aimed to develop a linear regression model to estimate NC using NoSAS variables. 3,109 subjects from the Sleep Health Heart Study database were included (56% man; 62 ± 10 years; body mass index [BMI] = 28.6 ± 4.8 kg/m2; NC = 38.5 ± 4.8 cm; apnea-hypopnea index = 14.5). Four multiple linear regression models were developed: 1) Age, BMI, sex, snoring; 2) Age, height, weight, sex, snoring; 3) Sex, BMI; 4) Sex, weight. Models 3 and 4 included the most significant variables of models 1 and 2, identified through permutation feature importance. For fitting and evaluating the models, participants were allocated into training/validation (80%) and testing (20%) sets. Model 3 (mean absolute error = 1.72 cm, mean absolute percentage error = 4.49%, and R2 = 0.72) was selected for further evaluation due to its simplicity, resulting in the following formula for estimated NC: eNC = 22.9 + 0.438×BMI + 5.435×Male. Using eNC instead of true NC did not reduce the performance of NoSAS in identifying individuals at high risk of OSA. The presented model for NC estimation can be utilized to assess OSA risk when NC measurement is unavailable.

Authors: Rajaraman Vaishnavi , Kumary Beena 
Published: December 2024

Abstract

Background: A broad range of Müllerian anomalies have been documented, and multiple anomalies can coexist in a single individual. Accurate identification of the different components of an anomaly is crucial for determining an effective treatment plan. This report presents an extremely rare case of a Müllerian anomaly in a 34-year-old nulliparous woman.
Case Presentation: A 34-year-old nulliparous woman presented to the outpatient department with a six-month history of dyspareunia, without any associated menstrual irregularities or disturbances. Perineal examination revealed a blind-ending vaginal pouch measuring 1 cm, along with a septum and a narrowed vaginal orifice. Ultrasound and pelvic MRI were critical in establishing the diagnosis of a Müllerian anomaly.
Discussion: Although this is a rare presentation, it is essential to have a structured protocol for accurate diagnosis and management of Müllerian anomalies to ensure favorable outcomes. The patient underwent a complete septal resection, which successfully addressed her symptoms. This case emphasizes the importance of early and precise diagnosis using imaging modalities such as ultrasound and MRI for planning effective treatment and improving the patient's quality of life.

Published: December 2024

Abstract

Objectives
The Atherogenic Index of Plasma (AIP) value is relationship with the risk of atherosclerosis, a known risk factor for cardiovascular events. However, studies on the correlation between AIP value and ischemic stroke (IS) in the diabetic population in Intensive Care Unit (ICU) are rare. Our study aimed to investigate the relationship between AIP values and IS among diabetic patients in American ICUs.
Methods
A multicenter retrospective cohort study comprising 3695 patients from the eICU-CRD v2.0 database between 2014 and 2015 in the USA was conducted. We utilized logistic regression model to investigate the correlation between between AIP values and IS among diabetic patients in American ICUs. To detect possible non-linear associations, we combined logistic regression with generalized additive model (GAM). Additionally, we conducted a thorough array of sensitivity and subgroup analyses to verify the robustness of our results.
Results
The prevalence of IS was 19.46%. The median AIP was 0.52 (interquartile range, 0.29-0.76). Participants with stroke exhibited a significant elevation in AIP levels. In particular, each one-unit elevation in AIP levels was associated with a 40% increased risk of IS (OR=1.4, 95% CI 1.1-2.8, P<0.001). In addition, a non-linear relationship exists between the AIP value and the incidence of IS, with an inflection point at 0.8. The effect sizes (OR) on the left and right sides of the inflection point were 0.9 (95%CI: 0.5-1.8; P= 0.741) and 1.7 (95%CI: 1.2-2.5; P＜0.001 ), respectively.
Conclusion
The research uncovers a positive, non-linear correlation between the AIP value and IS incidence among diabetic patients in American ICUs. Notably, a significant association between the AIP value and IS emerges when the AIP value is less than 0.8. From a therapeutic perspective, reducing AIP levels below the inflection point seems reasonable. However, the findings require validation through prospective studies.

Abstract

Objective: To compare theintraoperative outcome and postoperativeefficacy of fully neuroendoscopic and microscopic microvascular decompression (MVD) under neurophysiological monitoring in the treatment of primary trigeminal neuralgia (PTN).
Methods: This retrospective study included 131 patients with PTN who were admitted to our hospital between January 2019 and October 2022. The patients were categorized according to the treatment received into the endoscopic group (n=53) (fully neuroendoscopic MVD) and the microscopic group (n=78) (microscopic MVD). All patients were treated under neurophysiological monitoring. The surgical time, identification of offending vessels, full exposure of trigeminal nerve structure, postoperative efficacy, complications, and recurrence rate were compared between both groups.
Results: There were differences in incision length and bone flap diameter between the two groups (P<0.05). Endoscopy was more minimally invasive compared to microscopy; however, there was no significant difference in surgical time and blood loss between the two groups (P>0.05). In the group with no neurovascular compression identified during preoperative assessment, the surgical duration was significantly shorter with endoscopy compared to microscopy (P < 0.05).The consistency rate of preoperative MRTA result and intraoperative offending vessels differed between the two groups (P<0.05), indicating that endoscopy may be more accurate than microscopy in detecting offending vessels. Compared to microscopes, endoscopes provide better exposure of the trigeminal nerve throughout the procedure, and the need to adjust the Teflon pledget is less frequent (P<0.05), thereby reducing the number of nerve disturbances. There was no significant difference in postoperative remission rate and BNI scores between the groups (P>0.05). Compared to the microscopy group, the recurrence rate at 2 years and the last follow-up after endoscopic surgery was lower; however, the difference was not significant (P>0.05). There was no significant difference in the incidence of postoperative complications, mortality rate, and length of hospital stay between the groups (P>0.05).
Conclusion: Endoscopic and microscopic microvascular decompression are effective for PTN and have comparable outcomes. Endoscopy enhances visualization and identification of offending vessels; moreover, compared with microscopy, endoscopy is more suitable for detecting and fully separating potentially hidden offending vessels; however, its technical complexity necessitates individualized treatment based on patient needs and institutional expertise.

Published: December 2024

Abstract

Addressing the growing issue of soil contamination requires identifying effective hyperaccumulator plant species, which are essential for the success and efficiency of phytoremediation. These unique plants can absorb and sequester metals at concentrations significantly higher than typical flora, offering a sustainable and eco-friendly solution. Phytoremediation, as the primary approach in this study, was explored to identify potential candidates for phytoextraction and phytostabilization among seven native plant species growing on manganese (Mn)-bearing soils derived from ultramafic rocks in the Abadeh-Tashk ophiolite complex, Iran. E. stellata was a promising Mn-hyperaccumulator suitable for phytoextraction in contaminated areas. In contrast, species like C. intricata, O. persica, and A. fasciculifolius exhibited high bioconcentration factors (BCFs) alongside low translocation factors (TFs), suggesting their potential for Mn phytostabilization. Further analysis of individual elements revealed that these species, with BCF > 1 and TF < 1, were also suitable candidates for Cu phytostabilization. Additionally, C. intricata demonstrated strong nickel (Ni) accumulation, indicating its suitability for Ni phytostabilization. The study also examined factors influencing Mn uptake, including soil characteristics such as CaCO3 content, exchangeable Mn fraction, pH, organic matter (OM), soil texture, and cation exchange capacity (CEC). Results indicated that low CaCO3 content and alkaline soil pH enhanced Mn uptake, while clay loam texture and low OM limited Mn bioavailability, hindering its uptake by plants. This comprehensive investigation into Mn uptake and the identification of suitable plants for phytoremediation in the Abadeh-Tashk region offered valuable insights into the capabilities of hyperaccumulators in mitigating soil metal contamination. The study not only contributed to the understanding of environmental science but also provided promising solutions for soil restoration projects on a global scale.
Category-Level 6D Pose Estimation Based on Deep Cross-Modal Feature Fusion
Authors: Tang Chunhui , Zhang Mingyang , Zhao Yi , Shan Shouxue 
Published: December 2024

Abstract

Category-level 6D pose estimation methods aim to predict the rotation, translation, and size of unseen objects in a given category. RGB-D based dense correspondence methods have achieved leading performance. However, due to the differences in textures and shapes of the objects within a category, the object masks acquired by previous instance segmentation methods may be defective, resulting in inaccurate object point clouds acquired by depth map back-projection and RGB image patches acquired by cropping. Existing fusion methods that directly stitch RGB and geometric features cannot obtain accurate fused features. To solve these problems, we propose a new data processing method to improve the accuracy of the input data. The object position information provided by the object detection algorithm is fused with the image embedding information extracted through the vision transformer to obtain an accurate object mask. In addition, we introduce a new implicit fusion strategy that employs a cross-attention mechanism to align two different semantic features and subsequently reason about the fused features of the two different input data through a transformer-based architecture. We demonstrate the approach’s effectiveness by conducting experiments on two publicly available datasets, REAL275 and CAMERA275.

Abstract

Background: The most common severe inherited hemorrhagic disease is hemophilia, which means "love of blood." Deficiencies in Factors VIII and IX cause hemophilia, with inadequate levels or malfunctioning of these factors being the primary causes of hemophilia A and B, respectively. This study aims to assess the incidence and characteristics of inherited coagulation disorders, particularly hemophilia B.
Objective: The present investigation aims to evaluate the incidence and clinical traits of congenital anticoagulation diseases, specifically hemophilia B.
Method: The study included 98 Hemophilia B patients with a mean age of 25. Medical histories were recorded using a predesigned Performa, covering age, gender, bleeding site, and family history.
Result: The study included 98 hemophilia B patients, with 39 having severe and 59 moderate forms. The majority (60.2%) had moderate hemophilia, while 39.7% had the severe type. Most patients (17.4 ± 10.5 years) were aged 21-30, with the mean age of onset being 17.4±10.5 years for severe hemophilia and 8.6±4.43 years for moderate cases. Knee joints were the most affected, found in 79.5% of cases and accounting for 98.9% of target joint infections, followed by elbow joints at 90.8%. Regular factor IX replacement was needed in 39.7% of severe cases. This highlights the importance of early diagnosis and treatment for managing joint-related complications in hemophilia B patients.
Conclusion: The current study examines hemophilia B's sociodemographic and clinic-pathological characteristics. Early diagnosis may be beneficial only when the spectral manifestation of hemophilia B in the community is known.

Published: December 2024

Background
Chronic heart failure (CHF) is a serious threat to human health, with high morbidity and mortality rates, imposing a heavy burden on the health care system and society. With the abundance of medical data and the rapid development of machine learning (ML) technologies, new opportunities are provided for in-depth investigation of the mechanisms of CHF and the construction of predictive models. The introduction of health ecology research methodology enables a comprehensive dissection of CHF risk factors from a wider range of environmental, social, and individual factors. This not only helps to identify high-risk groups at an early stage but also provides a scientific basis for the development of precise prevention and intervention strategies.

Objective
This study aims to use ML to construct a predictive model of the risk of occurrence of CHF and analyze the risk of CHF from a health ecology perspective.

Methods
This study sourced data from the Jackson Heart Study database. Stringent data preprocessing procedures were implemented, which included meticulous management of missing values and the standardization of data. Principal component analysis and random forest (RF) were used as feature selection techniques. Subsequently, several ML models, namely decision tree, RF, extreme gradient boosting, adaptive boosting (AdaBoost), support vector machine, naive Bayes model, multilayer perceptron, and bootstrap forest, were constructed, and their performance was evaluated. The effectiveness of the models was validated through internal validation using a 10-fold cross-validation approach on the training and validation sets. In addition, the performance metrics of each model, including accuracy, precision, sensitivity, F1-score, and area under the curve (AUC), were compared. After selecting the best model, we used hyperparameter optimization to construct a better model.

Results
RF-selected features (21 in total) had an average root mean square error of 0.30, outperforming principal component analysis. Synthetic Minority Oversampling Technique and Edited Nearest Neighbors showed better accuracy in data balancing. The AdaBoost model was most effective with an AUC of 0.86, accuracy of 75.30%, precision of 0.86, sensitivity of 0.69, and F1-score of 0.76. Validation on the training and validation sets through 10-fold cross-validation gave an AUC of 0.97, an accuracy of 91.27%, a precision of 0.94, a sensitivity of 0.92, and an F1-score of 0.94. After random search processing, the accuracy and AUC of AdaBoost improved. Its accuracy was 77.68% and its AUC was 0.86.

Conclusions
This study offered insights into CHF risk prediction. Future research should focus on prospective studies, diverse data, advanced techniques, longitudinal studies, and exploring factor interactions for better CHF prevention and management.

Abstract
The paper presents new results of manufacturing coatings by magnetron sputtering to improve the functional properties of joint endoprostheses. The antibacterial properties of Ti-Cu and Ta-Cu coatings deposited by DC multi-magnetron sputtering on Ti6Al4V alloy substrates subjected of gas-abrasive treatment have been investigated. The roughness of the substrate was measured by optical profilometry. The coating hardness and elastic modulus were estimated by nanoindentation methods; the adhesion characteristics were assessed by Rockwell test. Scanning electron microscopy with energy-dispersive X-ray analysis verified the application of coatings with 25 at.% Cu, at thicknesses of 2 μm and 10 μm to roughened Ti6Al4V alloy. All coatings demonstrated sufficient adhesion, whereas Ta-Cu coatings generally revealed higher hardness, while the elastic modulus decreased with increasing coating thickness. Staphylococcus aureus strains were used for in vitro study of the antibacterial properties of Ti-Cu and Ta-Cu coatings. The largest zones of inhibition of bacteria S. aureus 23 mm were observed for 10 µm Ta-Cu coating thickness. The release dynamics of Cu ions from Ta-Cu and Ti-Cu coatings into physiological solution analyzed over seven days via inductively coupled plasma mass spectrometry, matched the inhibition zone growth. The Ti-Cu and Ta-Cu coatings of 2 µm thickness provided weaker antibacterial effect. The optimal parameters of magnetron sputtering of antibacterial Ti-Cu and Ta-Cu coatings on Ti6Al4 alloy substrates were selected. These findings support the potential of these coatings in developing endoprosthesis implants with enhanced antimicrobial and wear-resistant properties
