- Abstract
Despite the vast amount of restaurant information shared on social platforms, users often face difficulties identifying suitable options efficiently. Ratings are constrained by information narrowness, while textual reviews pose challenges due to information overload. Furthermore, restaurant recommendations based solely on ratings lack objectivity, as individual preferences differ. Users cannot judge whether a restaurant is worth visiting without credible information. However, few existing studies integrate semantic analysis with multidimensional orientation and social influence to make recommendations, leaving a gap in objective and comprehensive analysis. This research proposes a synthesis collective recommendation approach utilizing machine learning with aspect-based sentiment and social influence analyses. The proposed approach can appropriately adjust ratings as a basis for deciding the list of recommendations, considering location and preference factors. Experimental results show that the proposed mechanism significantly enhances users' ability to find restaurants that meet their needs, thereby improving business opportunities. [ABSTRACT FROM AUTHOR]

Objectives: Stroke is a leading cause of death in Taiwan. Poor public knowledge of stroke may lead to delays in prehospital arrival, resulting in unfavorable prognoses. Studies have investigated public knowledge of stroke and highlighted the importance of stroke education, however, few such studies have been conducted in Taiwan. This study assessed the changes in public knowledge of stroke between 2012 and 2020 by conducting a survey during two World Stroke Day events. Furthermore, this study identified areas where educational efforts may have been insufficient. Materials & Methods: Questionnaires were distributed to the participants of 2012 and 2020 World Stroke Day events in Taiwan. In total, 328 and 336 questionnaires were completed, respectively. Stroke literacy and knowledge were analyzed between 2012 and 2020. Data were analyzed using the chi-square test or independent t-test. p < 0.05 indicates statistical significance. Results: Hypertension was the most recognized risk factor for stroke in both years (p < 0.001), and recognition of most of the given risk factors significantly increased. In addition, recognition of more than half of the stroke warning signs significantly increased, awareness of the correct acute stroke response also increased (p < 0.001), and overall stroke literacy in Taiwan increased (p = 0.001). Conclusion: Stroke literacy and knowledge in Taiwan have improved significantly between 2012 and 2020, but many people still lack adequate stroke knowledge and awareness. Government health department must take this sort of intervention continually (campaigns) and novel approaches (e.g. board game...) to improve stroke literacy and knowledge in public health.

- Abstract
Sublobar resection of early-stage non-small cell lung cancer (NSCLC) is increasingly considered appropriate but may compromise margins compared with lobectomy. This study evaluated resection extent, margin status, and survival in patients with clinical stage I NSCLC. Patients with clinical T1-2 N0 M0 NSCLC in the National Cancer Database (2006-2020) who were treated with primary surgery were compared stratified by margin status. The potential benefit of radiation was explored in subgroup analysis of patients who underwent sublobar resection with positive margins. Positive margins occurred in 5089 (2.8%) of 181,824 patients and were more common in sublobar resections compared with lobectomy (4.3% vs 2.4%; P <.001). Sublobar resection had the strongest association with positive margins in multivariable analysis (odds ratio, 2.06; 95% CI, 1.91-2.23; P <.001). Patients with positive margins were more likely to undergo both adjuvant chemotherapy (16% vs 13%; P <.001) and radiation (17% vs 1%; P <.001) but had worse survival in univariate analysis (44.0% 5-year overall survival vs 69.2%; P <.001) and multivariable Cox analysis (hazard ratio, 1.71; 95% CI, 1.63-1.78; P <.001) in the entire cohort, as well as in a univariate subset analysis of lobectomy (46.9% vs 70.4%; P <.001) and sublobar resection (37.5% vs 64.1%; P <.001). Postoperative radiation for patients who underwent sublobar resection with positive margins did not improve 5-year overall survival (36.3% for irradiated patients vs 38.3% for nonirradiated patients; P =.57), and patients who underwent sublobar resection with positive margins who were treated with radiation had survival inferior to that of patients who underwent lobectomy with negative margins. Positive margins occur more frequently after sublobar resection of clinical stage I NSCLC compared with lobectomy. Patients with positive margins have worse survival than patients who undergo complete resection and are not rescued by postoperative radiation. [ABSTRACT FROM AUTHOR]

- Abstract
The gut microbiota prevents harmful microbes from entering the body, a function known as colonization resistance. The enteric pathogen Salmonella enterica serovar (S.) Typhimurium uses its virulence factors to break colonization resistance through unknown mechanisms. Using metabolite profiling and genetic analysis, we show that the initial rise in luminal pathogen abundance was powered by a combination of aerobic respiration and mixed acid fermentation of simple sugars, such as glucose, which resulted in their depletion from the metabolome. The initial rise in the abundance of the pathogen in the feces coincided with a reduction in the cecal concentrations of acetate and butyrate and an increase in epithelial oxygenation. Notably, these changes in the host environment preceded changes in the microbiota composition. We conclude that changes in the host environment can weaken colonization resistance even in the absence of overt compositional changes in the gut microbiota. [Display omitted] • Glucose fuels virulence factor-driven growth of Salmonella in the murine cecum • Colonization resistance becomes impaired when microbiota is compositionally intact • Colonization resistance is compromised when inflammation disrupts epithelial hypoxia • Aerobic respiration and fermentation of sugars support Salmonella outgrowth Rogers et al. show that Salmonella overcomes colonization resistance when the microbiota is compositionally intact by disrupting epithelial hypoxia. Pathogen outgrowth is fueled by catabolizing simple sugars, such as glucose, using a combination of aerobic respiration and mixed acid fermentation. [ABSTRACT FROM AUTHOR]

- Abstract
Sublobar resection offers noninferior survival vs lobectomy for ≤2 cm non-small cell lung cancer and is commonly used for subsolid tumors. Although data exist for solid tumors, the minimum adequate margin of resection for subsolid adenocarcinomas remains unclear. This was a retrospective review of 1101 adenocarcinoma resections at our institution from 2006 to 2022. Inclusion criteria were tumors ≤3 cm with ≥10% radiographic ground glass, excised by sublobar resection. Exclusions were positive nodes or positive or unreported margin. The primary outcome was the rate of local recurrence (LR) at multiple thresholds of margin distance. The relationship between margin distance and solid component size was also explored. Inclusion criteria were met by 194 patients. Median (interquartile range) tumor diameter and margin distance were 12 mm (9-17 mm) and 10 mm (5-17 mm), respectively. Median follow-up was 42.5 months. There was a progressive increase in LR with diminishing margin (0.1-cm decrements) from 1.5 cm to 0.5 cm. The difference in the rate of LR between "over" (n = 143) and "under" (n = 51) was most significant at 0.5 cm (8 of 51 [15.7%] vs 6 of 143 [4.2%]; P =.01) but did not reach α adjusted for multiple comparisons. On Cox regression for LR-free survival, margin ≤0.5 cm (P =.19) and solid component percentage (P =.14) trended to significance. Combining these using a ratio of margin distance–to–solid component size, a ratio of ≤1 showed a significantly higher rate of LR (7 [14.3%] vs 2 [2.0%], P =.009). Treatment of LRs provided at least intermediate-term survival in 87% of recurrences (median postrecurrence follow-up was 44 months). During sublobar resection of subsolid lung adenocarcinomas, a margin distance–to–solid component size ratio of >1.0 appears to be a more reliable factor than margin distance alone to minimize local recurrence. Local recurrence, however, may not impact survival in patients with subsolid adenocarcinomas if timely treatment is administered. [ABSTRACT FROM AUTHOR]

- Abstract
Lepidic-type adenocarcinomas (LPAs) can be multifocal, and treatment is often deferred until growth is observed. This study investigated the potential downside of that strategy by evaluating the relationship of nodal involvement with tumor size and survival. The impact of tumor size on lymph node involvement and survival was evaluated for National Cancer Database patients who underwent surgery without induction therapy as primary treatment for cT1-3 N0 M0 histologically confirmed LPA from 2006 to 2019 by using logistic regression, Kaplan-Meier, and Cox analyses. Positive nodes occurred in 442 of 8286 patients (5.3%). The incidence of having positive nodes approximately doubled with each 1-cm increment increase in size. Patients with positive nodes were more likely to have larger tumors (27 mm vs 20 mm, P <.001) and clinical ≥T2 disease (40.7% vs 26.8%, P <.001) compared with node-negative patients. However, tumor size was the only significant independent predictor of having positive nodal disease in logistic regression analysis, and this association grew stronger with each incremental centimeter increase in size. Patients with positive nodes were more likely to undergo adjuvant radiotherapy (23.5% vs 1.1%, P <.001) and chemotherapy (72.9% vs 7.9%, P <.001), and expectedly, had worse survival compared with the node-negative group in univariate (5-year overall survival, 50.9% vs 81.1%, P <.001) and multivariable (hazard ratio, 2.56; 95% CI, 2.14-3.05; P <.001) analyses. Nodal involvement is relatively uncommon in early-stage LPAs but steadily increases with tumor size and is associated with dramatically worse survival. These data can be used to inform treatment decisions when evaluating LPA patients. [ABSTRACT FROM AUTHOR]

- Abstract
Topologically protected magnetic skyrmions in magnetic materials are stabilized by an interfacial or bulk Dzyaloshinskii–Moriya interaction (DMI). Interfacial DMI decays with an increase of the magnetic layer thickness in just a few nanometers, and bulk DMI typically stabilizes magnetic skyrmions at low temperatures. Consequently, more flexibility in the manipulation of DMI is required for utilizing nanoscale skyrmions in energy-efficient memory and logic devices at room temperature (RT). Here, we demonstrate the observation of RT skyrmions stabilized by gradient DMI (g-DMI) in composition gradient-engineered CoPt single-layer films by employing the topological Hall effect, magnetic force microscopy, and nitrogen-vacancy scanning magnetometry. Skyrmions remain stable over a wide range of applied magnetic fields and are confirmed to be nearly Bloch-type from micromagnetic simulation and analytical magnetization reconstruction. Furthermore, we observe skyrmion pairs, which may be explained by skyrmion–antiskyrmion interactions. Our findings expand the family of magnetic materials hosting RT magnetic skyrmions by tuning g-DMI via gradient polarity and a choice of magnetic elements.

- Abstract
Quantum states can provide means to systematically manipulate the transport of electrons. Here we present electron transport across quasi-bound states of two heterogeneous quantum wells (QWs), where the transport of thermally excited electrons is blocked or enabled depending on the relative positions of the two quasi-bound states, with an abrupt current onset occurring when the two QW states align. The QW switch comprises a source (Cr), QW1 (Cr2O3), QW2 (SnOx, x< 2), a tunneling barrier (SiO2), and a drain (Si), where the effective electron mass of QW1 (m*QW1) is selected to be larger than QW2 (m*QW2). The current–voltage (I–V) measurements of the fabricated devices show abrupt current onsets, with the current transition occurring within 0.25 mV, corresponding to an effective electron temperature of 0.8 K at room temperature. Since transistor power consumption is fundamentally tied to effective electron temperature, this sub-1K cold-electron QW switching holds promise for highly energy-efficient computing.

- Abstract
ABSTRACTIntroductionScaffold hopping has emerged as a practical tactic to enrich the synthetic bank of small molecule antitumor agents. Specifically, it enables the chemist to refine the lead compound’s pharmacodynamic, pharmacokinetic, and physiochemical properties. Scaffold hopping opens up fresh molecular territory beyond established patented chemical domains.Area coveredThe authors present the scaffold hopping-based drug design strategies for dual inhibitory antitumor structural templates in this review. Minor modifications, structure rigidification and simplification (ring-closing and opening), and complete structural overhauls were the strategies employed by the medicinal chemist to generate a library of bifunctional inhibitors. In addition, the review presents an overview of the computational methods of scaffold hopping (software and programs) and organopalladium catalysis leveraged for the synthesis of templates designed via scaffold hopping.Expert opinionThe medicinal chemist has demonstrated remarkable prowess in furnishing dual inhibitory antitumor chemical architectures. Scaffold hopping-based drug design strategies have yielded a plethora of pharmacodynamically superior dual modulatory antitumor agents. An integrated approach involving computational advancements, synthetic methodology advancements, and conventional drug design strategies is required to increase the number of scaffold-hopping-assisted drug discovery campaigns.

- Abstract
Precedential evidence ascertaining the overexpression of LSD1 and HDACs in colorectal cancer spurred us to design a series of dual LSD1-HDAC inhibitors. Capitalizing on the modular nature of the three-component HDAC inhibitory model, tranylcypromine as a surface recognition motif was appended to zinc-binding motifs via diverse linkers. A compendium of hydroxamic acids was generated and evaluated for in vitrocytotoxicity against HCT-116 cells (human colorectal cancer cell lines). The most potent cell growth inhibitor 2(GI50= 0.495 μMm HCT-116 cells) shows promising anticancer effects by reducing colony formation and inducing cell cycle arrest in HCT-116 cells. It exhibits preferential inhibition of HDAC6, along with potent inhibition of LSD1 compared to standard inhibitors. Moreover, Compound 2upregulates acetyl-tubulin, acetyl-histone H3, and H3K4me2, indicative of LSD1 and HDAC inhibition. In vivo, it demonstrates significant antitumor activity against colorectal cancer, better than irinotecan, and effectively inhibits growth in patient-derived CRC organoids.

- Abstract
Organic electrode materials for rechargeable batteries show great promise for improving the storage capacity, reducing production costs, and minimizing environmental impact toward sustainability. In this study, we report a series of newly synthesized arylamine-based polyimides, TPPA-PIs, with three different bridge functionalizations on the imide rings and isomeric constituents that can work as versatile battery electrodes. As a lithium-ion battery cathode, a maximum energy density of 248 Wh kg–1with high voltage operation up to 4.0 V can be achieved. As a lithium-ion battery anode, the TPPA-PIs showed a reversible storage capacity of 806 mA h g–1at 100 mA g–1current density with good rate capability up to a current density of 2000 mA g–1. Moreover, when applied as sodium-ion battery anodes, TPPA-PIs delivered an optimum specific capacity of up to 218 mA h g–1after 50 cycles at a 50 mA g–1current density and revealed a long cycling stability up to 1000 cycles under a high current density of 1000 mA g–1. More importantly, these electrochemical performances of TPPA-PIs are among the best compared with other reported polymer-based electrodes. The mechanistic studies show that both bridge functionalization on the imide units and isomerism impact the electrochemical performance by regulating their intrinsic properties such as charge storage behavior, ion diffusivity, and activation energy. We believe that such a detailed study of the structural design to electrochemical performance of these polymeric electrodes will offer insights into materials development and optimization for next-generation multifunctional energy storage devices in a wide range of applications.

- Abstract
Controlling the surface diffusion of particles on 2D devices creates opportunities for advancing microscopic processes such as nanoassembly, thin-film growth, and catalysis. Here, we demonstrate the ability to control the diffusion of F4TCNQ molecules at the surface of clean graphene field-effect transistors (FETs) via electrostatic gating. Tuning the back-gate voltage (VG) of a graphene FET switches molecular adsorbates between negative and neutral charge states, leading to dramatic changes in their diffusion properties. Scanning tunneling microscopy measurements reveal that the diffusivity of neutral molecules decreases rapidly with a decreasing VGand involves rotational diffusion processes. The molecular diffusivity of negatively charged molecules, on the other hand, remains nearly constant over a wide range of applied VGvalues and is dominated by purely translational processes. First-principles density functional theory calculations confirm that the energy landscapes experienced by neutral vs charged molecules lead to diffusion behavior consistent with experiment. Gate-tunability of the diffusion barrier for F4TCNQ molecules on graphene enables graphene FETs to act as diffusion switches.

- Abstract
ABSTRACTIntroductionSpleen tyrosine kinase (SYK), a nonreceptor tyrosine kinase, has emerged as a vital component in the complex symphony of cancer cell survival and division. SYK activation (constitutive) is documented in various B-cell malignancies, and its inhibition induces programmed cell death. In some instances, it also acts as a tumor suppressor.Areas coveredInvolvement of the SYK in the cancer growth, specifically in the progression of chronic lymphocytic leukemia (CLL), diffuse large B cell lymphomas (DLBCLs), acute myeloid leukemia (AML), and multiple myeloma (MM) is discussed. Therapeutic strategies to target SYK in cancer, including investigational SYK inhibitors, combinations of SYK inhibitors with other drugs targeting therapeutically relevant targets, and recent advancements in constructing new structural assemblages as SYK inhibitors, are also covered.Expert opinionThe SYK inhibitor field is currently marred by the poor translation rate of SYK inhibitors from preclinical to clinical studies. Also, dose-limited toxicities associated with the applications of SYK inhibitors have been evidenced. Thus, the development of new SYK inhibitory structural templates is in the need of the hour. To accomplish the aforementioned, interdisciplinary teams should incessantly invest efforts to expand the size of the armory of SYK inhibitors.

- Abstract
In the field of stock price forecasting, we are actively seeking to integrate various information to more accurately grasp market dynamics. Although historical stock prices and financial news have been widely used in previous studies, it is relatively rare to find research considering news-based, technical, and chip factors simultaneously and evaluating their combined effect. In this study, we innovatively propose a multi-kernel model that not only combines news-based, technical, and chip factor analysis but also utilizes market data provided by the Taiwan Stock Exchange, including institutional trading situations and stock price technical indicators. The aim is to further enhance the prediction accuracy of stock price dynamics. Based on the frequency of word occurrences, we design a new discriminant index to extract features highly correlated with stock prices from financial news. The empirical results show that our multi-kernel model significantly surpasses the single-kernel model in prediction accuracy. However, we also find that although financial news is somewhat correlated with stock price dynamics, information such as chip factors and stock price technical indicators contribute more significantly in our model. This further validates that our multi-kernel learning algorithm can effectively handle multifaceted data sources and give appropriate weights according to the importance of each data point, thereby enhancing the comprehensiveness of prediction. Through this research, we hope to bring new perspectives and inspirations to the field of stock price forecasting.

- Abstract
Objectives: There is an increasing incidence and prevalence of patients with chronic kidney disease (CKD) worldwide. Little is known the prevalence of CKD among older patients with schizophrenia. The purpose of this study was to investigate the prevalence of CKD and its risk factors in older adults with schizophrenia. Methods: In this cross-sectional study, a convenience sample of 240 patients with schizophrenia age 50 or older was recruited. In addition to demographic and clinical data, participants' estimated glomerular filtration rate was calculated using the Modification of Diet in Renal Disease equation based on age, sex, ethnicity, and serum creatinine level determined from a blood sample taken from participants. Results: The overall prevalence of CKD was 11.3%. Those with CKD were older, had a longer duration of psychiatric illness, a higher body mass index (BMI), and diagnoses of hypertension compared to those in the non-CKD group. Independent of other risk factors, older age and BMI were significantly associated with CKD. Conclusions: This study found that the overall prevalence of CKD in older patients with schizophrenia was 11.3%. Independent risk factors for CKD in this population were older age and higher BMI. In addition to early identification and early treatment of CKD in older patients with schizophrenia, clinicians should actively manage the risk factors identified in this study.

The purpose of this study was to develop two pictorial tools for assessing the attitudes of Taiwanese male senior high school students with intellectual disabilities toward sexually offensive behavior, focusing on cognitive distortion and victim empathy. A total of 181 male high school students at special education schools participated in this study. The validity and reliability were examined using exploratory factor analysis and Cronbach's alpha coefficient. For the cognitive distortion scale, 18 items grouped into three factors, rationalization, denial, and victim blaming, and explained 69.72% of the variance; for the victim empathy scale, 12 items grouped into two factors, the victim's feelings when the offensive behavior is perpetrated by another, and the victim's feelings when the offensive behavior is perpetrated by oneself, and explained 68.00% of the variance. The reliability was.96 for the cognitive distortion scale and.93 for the victim empathy scale. In conclusion, the two scales developed in this research were found to be reliable and valid tools for evaluating male students' attitudes toward sexually offensive behavior, and can also be used as reference material for courses in sex education.

- Abstract
Chemokines are small, secreted cytokines crucial in the regulation of a variety of cell functions. The binding of chemokine C-X-C motif chemokine ligand 12 (CXCL12) (stromal cell-derived factor 1) to a G-protein-coupled receptor C-X-C chemokine receptor type 4 (CXCR4) triggers downstream signaling pathways with effects on cell survival, proliferation, chemotaxis, migration, and gene expression. Intensive and extensive investigations have provided evidence suggesting that the CXCL12-CXCR4 axis plays a pivotal role in tumor development, survival, angiogenesis, metastasis, as well as in creating tumor microenvironment, thus implying that this axis is a potential target for the development of cancer therapies. The structures of CXCL12 and CXCR4 have been resolved with experimental methods such as X-ray crystallography, NMR, or cryo-EM. Therefore, it is possible to apply structure-based computational approaches to discover, design, and modify therapeutic molecules for cancer treatments. Here, we summarize the current understanding of the roles played by the CXCL12-CXCR4 signaling axis in cellular functions linking to cancer progression and metastasis. This review also provides an introduction to protein structures of CXCL12 and CXCR4 and the application of computer simulation and analysis in understanding CXCR4 activation and antagonist binding. Furthermore, examples of strategies and current progress in CXCL12-CXCR4 axis-targeted development of therapeutic anticancer inhibitors are discussed. [ABSTRACT FROM AUTHOR]

This study aimed to investigate the influence of immunonutritional factors on treatment-related toxicities and survival outcomes in patients with cervical cancer undergoing definitive radiochemotherapy. Patients with cervical cancer who received curative radiochemotherapy between 2016 and 2021 were retrospectively investigated. Pretreatment prognostic nutritional index (PNI), neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), and platelet-lymphocyte ratio (PLR) were measured. Survival outcomes, acute and late toxicities were evaluated. Among the 138 patients, those with larger tumor diameters had significantly lower pre-treatment PNI (p = 0.005). Pre-treatment immunonutritional factors were predictive of clinical survival, whereas post-treatment factors did not correlate with prognosis. Patients with low pre-treatment PNI (<49.5) or high NLR (>2.4) had shorter progression-free survival (PFS, HR: 1.86, p = 0.045 for PNI; HR: 3.15, p = 0.002 for NLR) and overall survival (OS, HR: 1.80, p = 0.048 for PNI; HR: 3.83, p = 0.015 for NLR). High pre-treatment NLR was associated with an increased risk of acute diarrhea (p = 0.049) and late severe toxicities (p = 0.046). Combined analysis revealed that pre-treatment good nutritional status and low systemic inflammation were linked to longer PFS (p = 0.007) and OS (p = 0.002), and poor nutritional status and substantial systemic inflammation were associated with higher rates of late severe toxicities (p = 0.036), with higher prognostic value in advanced stage patients. Pretreatment immunonutritional measures serve as quantitative biomarkers for predicting survivals and treatment toxicities in patients with cervical cancer treated with definitive radiochemotherapy.

- Abstract
This paper empirically analyzes the impact of social security contributions on firm performance using data from China's Shanghai and Shenzhen A-share listed companies from 2010 to 2022. The findings show that social security contributions have an inverted U-shaped relationship with firm performance, which is due to the fact that the human capital effect of social security contributions is greater than the crowding-out effect before the optimal point, and the crowding-out effect is greater than the human capital effect after the optimal point is reached. The above conclusion still holds after a series of robustness tests. In addition, this paper constructs the optimal social security contribution rate for enterprise performance from the relevant theory of factor endowment change in new structural economics, and at the same time finds that deviation from the optimal social security contribution rate reduces enterprise performance. This paper analyzes the heterogeneous roles played by both the social security contribution rate and the optimal social security contribution rate, and it can be found that these results vary across firms with different property rights and factor intensities. The findings of this paper provide policy considerations for setting the optimal social security contribution rate.

- Abstract
Laser powder bed fusion (LPBF) is a subset of the additive manufacturing process in which a laser beam selectively joins the metal powder into a desired part in a sequential layer process. Owing to its complex nature of rapid heating and cooling of the melt pool, there is a need to understand the melt pool behavior and its effects on the final manufactured part. A densely packed powder bed is highly desirable for fabricating a superior part using the LPBF process. In this work, discrete element model was used to generate powder beds with realistic powder properties and various factors affecting the packing density were studied. The powder beds generated were then irradiated with a high-power laser source to selectively melt the powder particles to study the melt pool dynamics using volume of fluid method. The effect of laser parameters like laser power and scan speed on the melt pool was studied using single-track and multi-track simulations. Multi-layer simulations were performed to replicate the actual LPBF process. The simulations were in close agreement with actual experimental efforts.

- Abstract
Tooth decay is a chronic disease resulting in pain, infection, and tooth loss. This illness is common because many factors, such as poor oral hygiene, sugar consumption, and microbial flora, contribute to dental cavities. Untreated or undetected tooth decay often escalates to a more severe stage, emphasizing the importance of early detection and intervention. We propose a portable, low-cost, and ergonomic optoelectronic device to provide a possible solution for the early detection of dental cavities before annual or regular dental checkups for the first time. This device integrates mini cameras on top of a dental impression tray to capture images of the teeth, and the photographs can be transmitted via Wi-Fi to the cloud for real-time cavity detection through a you only look once (YOLO) algorithm that is based on a convolutional neural network (CNN). Our results show the precision, recall, and mean average precision (mAP)@0.5:0.95 for YOLOv5 (0.72, 0.70, 0.75), YOLOv6 (0.59, 0.50, 0.58), and YOLOv7 (0.93, 0.94, 0.82). We also compared the YOLO algorithm with traditional techniques such as support vector machine (SVM) and k-nearest neighbor (kNN) algorithms. This intraoral cavity detection system paves the way for early detection of dental cavities with quick accessibility and affordable cost. We foresee that this optoelectronic device will play a role in advancing biomedical technologies, ultimately promoting the long-term well-being of individuals.

[Display omitted] • Hydrothermally synthesized BiOCl was ultrasonically combined with hollow-shaped f-CNT for the detection of pharmaceutical drug AAP. • BiOCl/f-CNT electrocatalytic activity for AAP was assessed using CV and DPV techniques. • This sensor demonstrated wide linear ranges with low detection limits. Acetaminophen (AAP) is well recognized as a pharmaceutical agent but prolonged consumption of AAP causes serious health issues for human beings. Herein we focus on BiOCl implanted with functionalized carbon nanotube (f-CNT) used to predict AAP levels in the human body samples by electrochemical detection. Bismuth Oxy Chloride (BiOCl) improves electrochemical performance with its electrochemical active sites, it suffers from sluggish kinetics with electron transfer. The composites of BiOCl and f-CNT are well-dispersed substantially, and the synergistic interface between BiOCl and f-CNT improves the electron transfer properties, alongside the catalytic activity enhanced with the large surface area of f-CNT. Notably, the BiOCl/f-CNT/Glassy carbon electrode (GCE) composite exhibits an excellent redox AAP detection in the electrochemical methods of cyclic voltammetry and different pulse voltammetry in pH-7.0 phosphate buffer solution at 0.4 V. The BiOCl/f-CNT composite achieves an outstanding lower detection limit of 0.0016 µM with a wide linear range of 0.01 to 650 µM of AAP with a higher sensitivity of 0.8754 µA µM
−1 cm−2 . Moreover, composite additionally depicts good selectivity and outstanding repeatability, reproducibility, and strong stability. However, human urine and blood serum gain insights into the clinical detection of AAP with an Acceptable recovery range. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Background: It remains unknown whether estimated glomerular filtration rate (eGFR) using the refit Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation without a term for race is associated with mortality and the need for kidney replacement therapy (KRT) differentially between Black and White heart transplant recipients. Methods: We studied 25,900 adults included in the Scientific Registry of Transplant Recipients. We classified recipients into six categories of eGFR (< 30, 30 to < 45, 45 to < 60, 60 to < 90, 90 to < 120, ≥ 120 ml/min/1.73 m
2 ) using the race-neutral CKD-EPI refit equation, and assessed survival with multivariable adjusted Cox proportional hazards regression. Results: The association between pre-transplant race-neutral eGFR and mortality varied by race (Pinteraction = 0.006). Compared to White patients with an eGFR of 90–120 ml/min/1.73 m2 , the mortality rates were 57% (95% CI 1.25, 1.98), 29% (95% CI 1.11, 1.51), 34% (95% CI 1.19, 1.52), and 19% (95% CI 1.06, 1.33) higher in Black patients with an eGFR less than 30, 30–45, 45–60, and 60–90 ml/min/1.73m2 , respectively; and 53% (95% CI 1.28, 1.82), 49% (95% CI 1.33, 1.66), and 23% (95% CI 1.11, 1.35) higher among White patients with an eGFR less than 30, 30–45, and 45–60 ml/min/1.73 m2 , respectively. The association between pre-transplant eGFR and the need for KRT during follow-up was similar between Black and White patients (Pinteraction = 0.57). Conclusions: Worsening pre-transplant eGFR using the new race-neutral CKD-EPI refit equation was associated with a higher rate of post-heart transplant mortality and KRT in Black and White recipients. The racial disparity in post-heart transplant mortality was narrower in the setting of severe kidney dysfunction. Graphical abstract:- Published

- Abstract
Purpose: Parkinson’s disease (PD) is a complex neurodegenerative disorder characterized by diverse symptoms. Diagnosis relies on established criteria and comprehensive assessment. The Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) motor score assesses motor function but is susceptible to rater variability. This study employs MediaPipe and video-assisted methods to objectively calculate real-time motion parameters, aiming to enhance diagnostic accuracy and mitigate inter-rater discrepancies in PD assessment. Methods: Between 2021 and 2022, 30 videos featuring patients with PD were recorded at Kaohsiung Medical University Chung-Ho Memorial Hospital and Kaohsiung Municipal Ta-Tung Hospital, compared with 30 normal controls. Using MediaPipe landmark detection, five movements were analyzed, and experienced specialists assessed movement severity based on MDS-UPDRS Motor Section. Results were organized for statistical analysis. Results: Significant differences in various motion parameters were observed between normal individuals and patients with PD (p< 0.007). Motion severity, assessed by pose tracking, strongly correlated with MDS-UPDRS motor section as rated by movement disorder specialists (p < 0.05). Even patients with mild symptoms showed differences from the control group (p < 0.05). Conclusion: MediaPipe and video-assisted landmark detection provide an objective tool for assessing PD bradykinesia symptoms, which is comparable to manual rating, exhibiting good sensitivity even for very mild symptoms.

- Abstract
To analyze the admission and treatment process of potentially COVID-19-infected patients in the intensive care unit under normalization, prevention, and control of the pandemic. A multidisciplinary team was assembled to develop a flowchart of potentially COVID-19-infected patients admitted to the intensive care unit and identify potential failure steps and modes throughout the process using the failure mode and effect analysis method. Through risk priority number (RPN) analysis of each failure mode, those with the highest impact on nosocomial infection were identified, and the priority of implementation was determined. Related corrective measures have been developed to continuously improve clinical practice and management. Eighty potential failure modes were identified, and 8 potential failure modes were identified with RPNs greater than 100. These high RPNs of the failure modes were associated with careless inquiries of epidemiological histories by nurses, inadequate implementation of management standards by nursing assistants, and exposure of attending physicians to potentially risky environments. Finally, 18 general corrective measures are proposed. Application of the failure mode and effect analysis method for quality improvement is a powerful tool for predicting potential failures in the process and can suggest corrective measures that could help avoid nosocomial infection during a pandemic. • This study examines the use and efficacy of failure mode and effect analysis (FMEA) in analyzing the journey of a potentially COVID-19 infected patient through the ICU admission, treatment, and discharge process as a means to identify and control nosocomial disease outbreak. • By identifying the most likely failure modes in the process and assigning risk priority numbers, we were able to develop corrective measures that are applicable from admission to discharge. • Our study makes a significant contribution to the literature because the FMEA tool has not previously been applied in the intensive care setting during the COVID-19 outbreak.

A contest sponsor or crowdsourcing intermediary hosting an open innovation contest can employ knowledge sharing activities such as panels, meetings, or even community forums to help maximize each contestant’s performance. However, in addition to the paradox of openness resulting from the incentive to protect their knowledge assets, contestants face a predicament related to sharing, as benevolently helping others may reduce their opportunity to win the contest. In this research, we integrate two stylized models to determine how a contest sponsor can most efficiently deploy its resources under budget constraints, and explore how to stimulate co-creation in knowledge-sharing activities. Our findings indicate that employing educational workshops to encourage brainstorming among contestants before submitting their work results may be inefficient if the prize is too high. In addition, if a contest sponsor values the overall contribution made by contestants, encouraging knowledge-sharing behavior can benefit the intermediary in a crowdsourcing-based open innovation contest when the number of contestants and the contest sponsor’s budget are set appropriately.

• The presence of multiple elements, each with distinct mixing affinities, promotes an accelerated amorphization. The energetic state and atomic size disparities among these elements render the amorphous phase resistant to crystalline reversion upon annealing. • The formation energies reveal that the amorphous structure assumes the most stable configuration and is energetically favorable relative to crystalline phases like BCC, FCC, and HCP, thereby driving the transformations. • High-energy mechanical milling induces distortion, antisite defects, and the formation of nanograin boundaries in the intermetallic phase, disrupting the order in atomic configuration and promoting amorphization. We describe a novel mechanism for the synthesis of a stable high-entropy alloy powder from an otherwise immiscible Mg-Ti rich metallic mixture by employing high-energy mechanical milling. The presented methodology expedites the synthesis of amorphous alloy powder by strategically injecting entropic disorder through the inclusion of multi-principal elements in the alloy composition. Predictions from first principles and materials theory corroborate the results from microscopic characterizations that reveal a transition of the amorphous phase from a precursor intermetallic structure. This transformation, characterized by the emergence of antisite disorder, lattice expansion, and the presence of nanograin boundaries, signifies a departure from the precursor intermetallic structure. Additionally, this phase transformation is accelerated by the presence of multiple principal elements that induce severe lattice distortion and a higher configurational entropy. The atomic size mismatch of the dissimilar elements present in the alloy produces a stable amorphous phase that resists reverting to an ordered lattice even on annealing.

- Abstract
We aimed to assess the secular trend of the global prevalence of Helicobacter pylori (H pylori) infection in adults and children/adolescents and to show its relation to that of gastric cancer incidence. We performed a systematic review and meta-analysis to calculate overall prevalence, adjusted by multivariate meta-regression analysis. The incidence rates of gastric cancer were derived from the Global Burden of Disease Study and Cancer Incidence in Five Continents. Of the 16,976 articles screened, 1748 articles from 111 countries were eligible for analysis. The crude global prevalence of H pylori has reduced from 52.6% (95% confidence interval [CI], 49.6%–55.6%) before 1990 to 43.9% (95% CI, 42.3%–45.5%) in adults during 2015 through 2022, but was as still as high as 35.1% (95% CI, 30.5%–40.1%) in children and adolescents during 2015 through 2022. Secular trend and multivariate regression analyses showed that the global prevalence of H pylori has declined by 15.9% (95% CI, −20.5% to −11.3%) over the last 3 decades in adults, but not in children and adolescents. Significant reduction of H pylori prevalence was observed in adults in the Western Pacific, Southeast Asian, and African regions. However, H pylori prevalence was not significantly reduced in children and adolescents in any World Health Organization regions. The incidence of gastric cancer has decreased globally and in various countries where the prevalence of H pylori infection has declined. The global prevalence of H pylori infection has declined during the last 3 decades in adults, but not in children and adolescents. The results raised the hypothesis that the public health drive to reduce the prevalence of H pylori as a strategy to reduce the incidence of gastric cancer in the population should be confirmed in large-scale clinical trials. [Display omitted] The prevalence of Helicobacter pylori has decreased from 52.6% (95% confidence interval, 49.6%–55.6%) before 1990 to 43.9% (95% confidence interval, 42.3%–45.5%) during 2015 to 2022 in adults, but not in children and adolescents, concomitant with a decrease of gastric cancer incidence globally and in various countries where the prevalence of Helicobacter pylori infection has declined.

An increasing body of evidence indicates correlations between the symptoms of temporomandibular disorder and those of eating disorder (ED). However, further investigation is required to elucidate the temporal and causal relationships between the aforementioned disorders. This retrospective cohort study was conducted using data from the Taiwan National Health Insurance Research Database. Temporomandibular joint disorder (TMJD) was analyzed both as the cause and consequence of ED. We collected the data (from January 1, 1998, to December 31, 2011) of patients with antecedent TMJD (N = 15,059) or ED (N = 1219) and their respective controls (1:10), matched by age, sex, income level, residential location, and comorbidities. This study included patients who had received a new diagnosis of an ED or a TMJD between January 1, 1998, and December 31, 2013. Cox regression models were used to assess the risk of ED or TMJD development in patients with antecedent TMJD or ED. TMJD patients had an approximately 3.70-fold (95 % confidence interval [CI]: 1.93–7.10) risk of ED development. Similarly, patients with ED had an approximately 4.78-fold (95 % CI: 2.52–9.09) risk of TMJD development. Subgroup analyses based on ED subtypes indicated antecedent TMJD and bulimia nervosa as the predictors of increased bulimia nervosa and TMJD risks (hazard ratios: 6.41 [95 % CI: 2.91 to 14.11] and 5.84 [95 % CI: 2.75 to 12.41]), respectively. Previous TMJD and ED are associated with increased risks of subsequent ED and TMJD; these findings suggest the presence of a bidirectional temporal association between TMJD and ED.

- Abstract
To identify meaningful changes in patients in 3 functional domains (basic mobility [BM], daily activity [DA], and applied cognition [AC]) after discharge from inpatient stroke rehabilitation and to identify the predictors of 1-year functional improvement. A longitudinal, multicenter, prospective cohort study. The acute care wards of 3 hospitals in the Greater Taipei area of Taiwan. Five hundred patients with stroke in acute care wards (mean age=60±12.2 years, 62% men, N=500). Not applicable. The Mandarin version of the Activity Measure for Post-Acute Care (AM-PAC) short forms were assessed at discharge and 3-, 6-, and 12-month follow-up. The minimal detectable change (MDC) was used to categorize changes in the scores as improved and unimproved at the 4 time points. The mean scores of the AM-PAC BM and DA subscales substantially increased over the first 3 months after discharge (86% of participants exhibited improvement) and slightly increased during the subsequent 9 months (5∼26% of participants exhibited improvement). However, the mean score of the AC subscale decreased within the first 3 months and increased over the subsequent 9 months (22-23% of participants exhibited improvement). The BM, AC scores at discharge were the dominant predictors of subsequent functional improvement (P <.05). Patients with a higher functional stage at discharge were more likely to experience significant improvement. This study established the capacity of the AM-PAC to predict functional improvement in 3 domains during the early, middle, and late stages of recovery. The findings can assist clinicians in identifying patients at risk of unfavorable long-term functional recovery and providing such patients with tailored interventions during the early stage of rehabilitation.

- Abstract
IMPORTANCE: Guidelines recommend seizure prophylaxis for early posttraumatic seizures (PTS) after severe traumatic brain injury (TBI). Use of antiseizure medications for early seizure prophylaxis after mild or moderate TBI remains controversial. OBJECTIVE: To determine the association between seizure prophylaxis and risk reduction for early PTS in mild and moderate TBI. DATA SOURCES: PubMed, Google Scholar, and Web of Science (January 1, 1991, to April 18, 2023) were systematically searched. STUDY SELECTION: Observational studies of adult patients presenting to trauma centers in high-income countries with mild (Glasgow Coma Scale [GCS], 13-15) and moderate (GCS, 9-12) TBI comparing rates of early PTS among patients with seizure prophylaxis with those without seizure prophylaxis. DATA EXTRACTION AND SYNTHESIS: The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) reporting guidelines were used. Two authors independently reviewed all titles and abstracts, and 3 authors reviewed final studies for inclusion. A meta-analysis was performed using a random-effects model with absolute risk reduction. MAIN OUTCOME MEASURES: The main outcome was absolute risk reduction of early PTS, defined as seizures within 7 days of initial injury, in patients with mild or moderate TBI receiving seizure prophylaxis in the first week after injury. A secondary analysis was performed in patients with only mild TBI. RESULTS: A total of 64 full articles were reviewed after screening; 8 studies (including 5637 patients) were included for the mild and moderate TBI analysis, and 5 studies (including 3803 patients) were included for the mild TBI analysis. The absolute risk reduction of seizure prophylaxis for early PTS in mild to moderate TBI (GCS, 9-15) was 0.6% (95% CI, 0.1%-1.2%; P = .02). The absolute risk reduction for mild TBI alone was similar 0.6% (95% CI, 0.01%-1.2%; P = .04). The number needed to treat to prevent 1 seizure was 167 patients. CONCLUSION AND RELEVANCE: Seizure prophylaxis after mild and moderate TBI was associated with a small but statistically significant reduced risk of early posttraumatic seizures after mild and moderate TBI. The small absolute risk reduction and low prevalence of early seizures should be weighed against potential acute risks of antiseizure medications as well as the risk of inappropriate continuation beyond 7 days.

- Abstract
Gypenoside XIII is isolated from Gynostemma pentaphyllum(Thunb.) Makino. In mice, G. pentaphyllumextract and gypenoside LXXV have been shown to improve non‐alcoholic steatohepatitis (NASH). This study investigated whether gypenoside XIII can regulate lipid accumulation in fatty liver cells or attenuate NASH in mice. We used HepG2 hepatocytes to establish a fatty liver cell model using 0.5 mM oleic acid. Fatty liver cells were treated with different concentrations of gypenoside XIII to evaluate the molecular mechanisms of lipid metabolism. In addition, a methionine/choline‐deficient diet induced NASH in C57BL/6 mice, which were given 10 mg/kg gypenoside XIII by intraperitoneal injection. In fatty liver cells, gypenoside XIII effectively suppressed lipid accumulation and lipid peroxidation. Furthermore, gypenoside XIII significantly increased SIRT1 and AMPK phosphorylation to decrease acetyl‐CoA carboxylase phosphorylation, reducing fatty acid synthesis activity. Gypenoside XIII also decreased lipogenesis by suppressing sterol regulatory element‐binding protein 1c and fatty acid synthase production. Gypenoside XIII also increased lipolysis and fatty acid β‐oxidation by promoting adipose triglyceride lipase and carnitine palmitoyltransferase 1, respectively. In an animal model of NASH, gypenoside XIII effectively decreased the lipid vacuole size and number and reduced liver fibrosis and inflammation. These findings suggest that gypenoside XIII can regulate lipid metabolism in fatty liver cells and improve liver fibrosis in NASH mice. Therefore, gypenoside XIII has potential as a novel agent for the treatment of NASH.

- Abstract
Clinical manifestations of phlebosclerotic colitis (PC) exhibit significant variability, necessitating diverse treatment strategies depending on disease severity. However, there is limited research exploring the relationship between imaging findings and disease severity. Hence, this retrospective study aimed to analyze the correlation between computed tomography (CT) findings, colonoscopic features, and disease severity. This study compared the abdominal CT characteristics, colonoscopy findings, and treatment modalities of 45 PC patients. CT images were assessed for the severity of mesenteric venous calcification, maximum colonic wall thickness, number of involved colonic segments, and presence of pericolic inflammation. Colonoscopic images were assessed for dark purple discoloration mucosa, erosive and ulcerative lesions, mucosal edema, luminal narrowing, and the number of involved colonic segments. In addition, patients were categorized into three groups: the observation (n= 15), medical treatment (n= 19), and operation (n= 11) groups. In CT images, a significant difference in pericolic inflammation (p= 0.039) was observed among groups. Further, significant differences in dark purple discoloration mucosa (p= 0.033), erosive or ulcerative lesions (p< 0.001), mucosal edema (p< 0.001), luminal narrowing (p= 0.012), and the number of involved colonic segments (p= 0.001) were observed in colonoscopy. Moreover, we found positive correlations between CT and colonoscopy features. In conclusion, CT manifestations and colonoscopy findings exhibited correlation with disease severity in PC. When limited to one diagnostic tool, observations from that tool can infer potential manifestations of the alternative tool.
