The Assembly of Cerium(III)-Containing Silicotungstate with Lewis Acid-Base Sites Enables the Selective C3-Alkenylation of Oxindole.

A cerium(III)-containing silicotungstate, [H2N(CH3)2]10NaK[KCe(SiW11O39)2(H2O)]·18.5H2O (CeSiW), was successfully synthesized and characterized. Structure analysis reveals that CeSiW is composed of two {SiW11O39} units connected by one cerium(III) cation to form a typical 1:2 sandwich structure, which is further expanding into a 1D chain linked by K+ ions. The oxygen-enriched surfaces of {SiW11O39} units and open cerium sites provide abundant Lewis base and acid sites in CeSiW. As a result, CeSiW efficiently catalyzed the C3-alkenylation of oxindoles with aldehydes through the simultaneous activation of both reaction substrates on its crystal framework. Various 3-benzylidene-oxindoles are synthesized with excellent yields and high E-selectivity under solvent-free conditions.

ER-mitochondria contact sites regulate hepatic lipogenesis via Ip3r-Grp75-Vdac complex recruiting Seipin.

BACKGROUND: Mitochondria and endoplasmic reticulum (ER) contact sites (MERCS) constitute a functional communication platform for ER and mitochondria, and they play a crucial role in the lipid homeostasis of the liver. However, it remains unclear about the exact effects of MERCs on the neutral lipid synthesis of the liver. METHODS: In this study, the role and mechanism of MERCS in palmitic acid (PA)-induced neutral lipid imbalance in the liver was explored by constructing a lipid metabolism animal model based on yellow catfish. Given that the structural integrity of MERCS cannot be disrupted by the si-mitochondrial calcium uniporter (si-mcu), the MERCS-mediated Ca2+ signaling in isolated hepatocytes was intercepted by transfecting them with si-mcu in some in vitro experiments. RESULTS: The key findings were: (1) Hepatocellular MERCs sub-proteome analysis confirmed that, via activating Ip3r-Grp75-voltage-dependent anion channel (Vdac) complexes, excessive dietary PA intake enhanced hepatic MERCs. (2) Dietary PA intake caused hepatic neutral lipid deposition by MERCs recruiting Seipin, which promoted lipid droplet biogenesis. (3) Our findings provide the first proof that MERCs recruited Seipin and controlled hepatic lipid homeostasis, depending on Ip3r-Grp75-Vdac-controlled Ca2+ signaling, apart from MERCs's structural integrity. Noteworthy, our results also confirmed these mechanisms are conservative from fish to mammals. CONCLUSIONS: The findings of this study provide a new insight into the regulatory role of MERCS-recruited SEIPIN in hepatic lipid synthesis via Ip3r-Grp75-Vdac complex-mediated Ca2+ signaling, highlighting the critical contribution of MERCS in hepatic lipid homeostasis.

Magnesium-promoted nickel-catalysed chlorination of aryl halides and triflates under mild conditions.

In this study, we present a ligand-free nickel(II)-catalyzed halogen exchange of aromatic halides with magnesium chloride. This method effectively facilitates the retro-Finkelstein reaction for a wide range of aryl bromides, iodides and triflates, demonstrating excellent functional group tolerance. Mechanistic studies reveal that magnesium plays a crucial role in the challenging reductive elimination from Ni(II) intermediates.

Mediastinal extension of pancreatic pseudocyst through the esophagus hiatus: A case report.

Pancreatic pseudocysts have a high amylase concentration and are surrounded by a fibrous capsule without a true epithelial lining. They are most frequently located in the peripancreatic region, and rarely extend into the mediastinum. We report a case of a 46-year-old male patient with a history of pancreatitis due to eat and drink too much presented with nausea and vomiting, MRI of the abdominal demonstrated a cystic mass connecting the abdominal cavity to posterior mediastinum and compressing the heart and stomach, ultrasound-guided aspiration of the cystic mass revealed high levels of amylase, conffrming that the mass was a rare pancreatic pseudocyst extending into the mediastinum. He was admitted for expectant management and was successfully treated with cystojejunostomy. This case aims to illustrate the possibility of rare pancreatic pseudocysts when a cystic mass is found that penetrates the abdominal and thoracic cavities.

Copper-nickel-MOF/nickel foam catalysts grown in situ for efficient electrochemical nitrate reduction to ammonia.

Reducing nitrate (NO3-) in an aqueous solution to ammonia under ambient conditions can provide a green and sustainable NH3-synthesis technology and mitigate global energy and pollution issues. In this work, a CuNi0.75-1,3,5-benzenetricarboxylic acid/nickel foam (CuNi0.75-MOF/NF) catalyst grown in situ was prepared via a one-pot method as an efficient cathode material for electrocatalytic nitrate reduction reaction (NO3RR). The CuNi0.75-MOF/NF catalyst exhibited excellent electrocatalytic NO3RR performance at -1.0 V versus a reversible hydrogen electrode, achieving an outstanding faradaic efficiency of 95.88 % and an NH3 yield of 51.78 mg h-1 cm-2. The 15N isotope labeling experiments confirmed that the sole source of N in the electrocatalytic NO3RR was the NO3- in the electrolyte. The reaction pathway for the electrocatalytic NO3RR was derived by in situ Fourier transform infrared spectroscopy and in situ differential electrochemical mass spectrometry. Density functional theory calculations revealed that the Ni element in the CuNi0.75-MOF/NF catalyst had excellent O-H activation ability and strong *H adsorption capacity. These *H species were transferred from the Ni sites to the *NO adsorption intermediates located on the Cu sites, providing a continuous supply of *H to Cu, thereby promoting the formation of *NOH intermediates and enhancing the hydrogenation process of the electrocatalytic NO3RR.

Modified furosemide responsiveness index and biomarkers for AKI progression and prognosis: a prospective observational study.

BACKGROUND: Modified furosemide responsiveness index (mFRI) is a novel biomarker for assessing diuretic response and AKI progression in patients with early AKI. However, the comparative predictive performance of mFRI and novel renal biomarkers for adverse renal outcomes remains unclear. In a single-center prospective study, we aimed to evaluate the discriminatory abilities of mFRI and other novel renal biomarkers in predicting AKI progression and prognosis in patients with initial mild and moderate AKI (KDIGO stage 1 to 2). RESULTS: Patients with initial mild and moderate AKI within 48 h following cardiac surgery were included in this study. The mFRI, renal biomarkers (including serum or urinary neutrophil gelatinase-associated lipocalin [sNGAL or uNGAL], serum cystatin C, urinary N-acetyl-beta-D-glycosaminidase [uNAG], urinary albumin-to-creatinine ratio) and cytokines (TNF, IL-1ß, IL-2R, IL-6, IL-8, and IL-10) were measured at AKI diagnosis. The mFRI was calculated for each patient, which was defined as 2-hour urine output divided by furosemide dose and body weight. Of 1013 included patients, 154 (15.2%) experienced AKI progression, with 59 (5.8%) progressing to stage 3 and 33 (3.3%) meeting the composite outcome of hospital mortality or receipt of renal replacement therapy (RRT). The mFRI showed non-inferiority or potential superiority to renal biomarkers and cytokines in predicting AKI progression (area under the curve [AUC] 0.80, 95% confidence interval [CI] 0.77-0.82), progression to stage 3 (AUC 0.87, 95% CI 0.85-0.89), and composite outcome of death and receipt of RRT (AUC 0.85, 95% CI 0.82-0.87). Furthermore, the combination of a functional biomarker (mFRI) and a urinary injury biomarker (uNAG or uNGAL) resulted in a significant improvement in the prediction of adverse renal outcomes than either individual biomarker (all P < 0.05). Moreover, incorporating these panels into clinical model significantly enhanced its predictive capacity for adverse renal outcomes, as demonstrated by the C index, integrated discrimination improvement, and net reclassification improvement (all P < 0.05). CONCLUSIONS: As a rapid, cost-effective and easily accessible biomarker, mFRI, exhibited superior or comparable predictive capabilities for AKI progression and prognosis compared to renal biomarkers in cardiac surgical patients with mild to moderate AKI.

GSP-AI: An AI-Powered Platform for Identifying Key Growth Stages and the Vegetative-to-Reproductive Transition in Wheat Using Trilateral Drone Imagery and Meteorological Data.

Wheat (Triticum aestivum) is one of the most important staple crops worldwide. To ensure its global supply, the timing and duration of its growth cycle needs to be closely monitored in the field so that necessary crop management activities can be arranged in a timely manner. Also, breeders and plant researchers need to evaluate growth stages (GSs) for tens of thousands of genotypes at the plot level, at different sites and across multiple seasons. These indicate the importance of providing a reliable and scalable toolkit to address the challenge so that the plot-level assessment of GS can be successfully conducted for different objectives in plant research. Here, we present a multimodal deep learning model called GSP-AI, capable of identifying key GSs and predicting the vegetative-to-reproductive transition (i.e., flowering days) in wheat based on drone-collected canopy images and multiseasonal climatic datasets. In the study, we first established an open Wheat Growth Stage Prediction (WGSP) dataset, consisting of 70,410 annotated images collected from 54 varieties cultivated in China, 109 in the United Kingdom, and 100 in the United States together with key climatic factors. Then, we built an effective learning architecture based on Res2Net and long short-term memory (LSTM) to learn canopy-level vision features and patterns of climatic changes between 2018 and 2021 growing seasons. Utilizing the model, we achieved an overall accuracy of 91.2% in identifying key GS and an average root mean square error (RMSE) of 5.6 d for forecasting the flowering days compared with manual scoring. We further tested and improved the GSP-AI model with high-resolution smartphone images collected in the 2021/2022 season in China, through which the accuracy of the model was enhanced to 93.4% for GS and RMSE reduced to 4.7 d for the flowering prediction. As a result, we believe that our work demonstrates a valuable advance to inform breeders and growers regarding the timing and duration of key plant growth and development phases at the plot level, facilitating them to conduct more effective crop selection and make agronomic decisions under complicated field conditions for wheat improvement.

Mapping oral medicine (stomatology) & oral and maxillofacial pathology international organizations: a scoping review of global data and historical analysis.

OBJECTIVES: To describe the historical evolution and dissemination of the Oral Medicine and Oral and Maxillofacial Pathology international societies and associations across the globe, and to provide insights into their significant contributions toward oral health promotion. STUDY DESIGN: This review was conducted in accordance with the JBI Scoping Review Methodology Group guidance. The reporting followed the Preferred Reporting Items for Systematic Reviews extension for Scoping Reviews (PRISMA-ScR). RESULTS: Search strategy was applied to 5 databases (MEDLINE/PubMed, Scopus, Embase, Web of Science, Latin American and Caribbean Health Sciences (LILACS)) and grey literature (Google Scholar, Open Grey and ProQuest), as well as additional sources, such as organization websites. Eighty-nine sources were included in this review. Forty-six professional associations/societies were identified, of which 39 represented a country or geopolitical region, 2 represented continents, 2 represented multinational organizations and 3 multinational study groups. CONCLUSIONS: Documentation of the historical establishment and development of Oral Medicine and Oral and Maxillofacial Pathology organizations worldwide is limited and describing these processes remains challenging. Analysis of global data reveals heterogeneous development and distribution, resulting in disparities in accessibility and standardization. Further efforts toward oral health promotion should be implemented.

Intranasal application of diluted saline alleviates ischemic brain injury in association with suppression of vasopressin neurons.

INTRODUCTION: Cerebral swelling and brain injury in ischemic stroke are closely related to increased vasopressin (VP) secretion. How to alleviate ischemic brain injury by suppressing VP hypersecretion through simply available approaches remains to be established. METHODS: Using a rat model of middle cerebral artery occlusion (MCAO), testing effects of intranasal application of 0.09% NaCl (IAL) on brain damages, VP neuronal activity, synaptic inputs, astrocytic plasticity, olfactory bulb (OB) activity in immunohistochemistry, patch-clamp recording, Western blotting and co-immunoprecipitation. RESULTS: IAL reduced MCAO-evoked neurological disorders, brain swelling, injury and loss of neurons, increase in c-Fos expression and excitation of supraoptic VP neurons. The effects of IAL on VP neurons were associated with its suppression of MCAO-evoked increase in the frequency of excitatory synaptic inputs and decrease in the expression of glial fibrillary acidic protein (GFAP) filaments around VP neurons. MCAO and IAL also caused similar but weaker reactions in putative oxytocin neurons. In the OB, MCAO also increased the firing rate of mitral cells in the lesioned side, which was reduced by IAL. Direct hypotonic challenge of OB slices increased the expression of glutamine synthetase and GFAP filaments in the glomerular bodies while reducing the firing rate of mitral cells. Blocking aquaporin 4 activity in the supraoptic and paraventricular nuclei in the MCAO side blocked MCAO-evoked VP increase and brain damages. CONCLUSION: IAL reduces ischemic stroke-evoked brain injury in association with suppressing VP neuronal activity through reducing excitatory synaptic inputs and astrocytic process retraction, which likely result from reducing mitral cell activation.

End-to-end [18F]PSMA-1007 PET/CT radiomics-based pipeline for predicting ISUP grade group in prostate cancer.

OBJECTIVES: To develop an end-to-end radiomics-based pipeline for the prediction of International Society of Urological Pathology grade group (ISUP GG) in prostate cancer (PCa). METHODS: This retrospective study includes 356 patients (241 in training set and 115 in independent test set) with histopathologically confirmed PCa who underwent [18F]PSMA-1007 PET/CT scan. Patients were classified into two groups according to their ISUP GG (1-3 vs. 4-5). Radiomics features were extracted from the whole, automatically segmented prostate on PET/CT images, 30 models were constructed by combining 6 feature selection algorithms and 5 machine learning classifiers. The clinical model incorporated age, total prostate-specific antigen (tPSA), maximum standardized uptake value (SUVmax), and prostate volume. The predictive performance of the models was evaluated using the area under the receiver operating characteristic curve (AUC), balanced accuracy (bAcc), and decision curve analysis (DCA). RESULTS: The best-performing radiomics model significantly outperformed clinical model (AUC 0.879 ± 0.041 vs. 0.799 ± 0.051, bAcc 0.745 ± 0.074 vs. 0.629 ± 0.045). On an external independent test set, best-performing radiomics model perform better than clinical model, with an AUC of 0.861 vs. 0.750, p = 0.002 (Delong), and bAcc of 0.764 vs. 0.582, p = 0.043 (McNemar). The learning curve, calibration curve and DCA demonstrated goodness-of-fit and improved benefits in clinical practice. CONCLUSION: The end-to-end radiomics-based pipeline is an effective non-invasive tool to predict ISUP GG in PCa.

An Analysis of Emergency Surgical Outcomes for Pediatric Traumatic Brain Injury: A Ten-Year Single-Institute Retrospective Study in Taiwan.

Background and Objectives: Pediatric traumatic brain injury (pTBI) remains a major pediatric public health problem, despite well-developed injury prevention programs. The purpose of this study is to analyze the emergency surgical outcomes of pTBI in a single institute ten-year retrospective study to offer a real-world clinical result. Materials and Methods: Our institute presented a clinical retrospective, single-institute research study of 150 pediatric TBI cases that were diagnosed and underwent emergency surgical treatment from 2010 to 2019. Results: The incidence of radiological findings is detailed as follows: brain edema (30%, 45/150), followed by acute subdural hematoma (27.3%, 41/150), epidural hematoma (21.3%, 32/150), chronic subdural hemorrhage (10%, 15/150), skull fracture (6.7%, 10/150), and traumatic subarachnoid hemorrhage (4.7%, 7/150). Surgical intervention data revealed that decompressive craniectomy was still the main effective surgical method. The results showed longer hospital stays and higher morbidity rates in the brain edema, acute subdural hematoma, and chronic subdural hemorrhage groups, which were viewed as poor surgical outcome groups. Epidural hematoma, skull fracture and traumatic subarachnoid hemorrhage were categorized into good surgical outcome groups. Notably, the data revealed gross improvement in Glasgow Coma Scale/Score (GCS) evolution after surgical interventions, and the time to cranioplasty was a significant factor in the development of post-traumatic hydrocephalus (PTH). Conclusions: Our study provided real-world data for the distribution of etiology in pTBI and also categorized it into six groups, indicating disease-orientated treatment. In addition, our data supported that decompressive craniectomy (DC) remains a mainstay surgical treatment in pTBI and early cranioplasty could decrease the incidence of PTH.

The Complete Mitochondrial Genome and Phylogenetic Analysis of Rhagastis binoculata (Matsumura, 1909) (Lepidoptera: Sphingidae).

The mitochondrial genome (mitogenome) Rhagastis binoculata (Matsumura, 1909), an endemic moth species in Taiwan, was sequenced and analyzed. The complete circular mitogenome of R. binoculata is 15,303 bp and contains 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and an AT-rich control region. The mitogenome has an overall nucleotide composition of 41.2% A, 11.9% C, 7.5% G, and 39.4% T, with an AT content of 80.6%. Of the protein-coding genes (PCGs), 12 start with ATG, ATT, and ATC, and COX1 starts with a "CGA" codon. All of the stop codons are "TAA, TAG, or T". Our phylogenetic analysis of 21 species of Sphingidae insects suggests that R. binoculata is clustered with Rhagastis mongoliana, which belongs to the subfamily Macroglossinae.

Surgical Outcomes of Open and Laparoscopic Hartmann Reversal: A Single-Center Comparative Study.

BACKGROUND AND OBJECTIVES: Hartmann reversal (HR) is challenging and traditionally requires a large laparotomy wound. With the development of minimally invasive techniques, laparoscopic reversal of Hartmann's operation (HO) was attempted. We aimed to evaluate the outcomes of laparoscopic Hartmann reversal (LHR) versus open Hartmann reversal (OHR). MATERIALS AND METHODS: In this study, we included 33 patients who underwent HR at Chi Mei Medical Center between January 2015 and March 2023. Ten patients received LHR, while 23 received OHR. We compared patient demographics, perioperative outcomes, early postoperative complications, and late postoperative complications between the two groups. RESULTS: There was no significant difference in the baseline demographics of both groups. Compared to the open method, the LHR group had a shorter hospital stay and time to solid diet. The median length of hospital stay in the OHR and LHR groups was 15.00 (Q1-Q3: 13.00-16.00) and 11.5 (Q1-Q3: 10.00-14.00) days (p = 0.028), respectively. The median time to solid diet was 8.00 (Q1-Q3: 7.00-8.00) days in the OHR group and 5.00 (Q1-Q3: 5.00-7.00) days in the LHR group (p = 0.022). No statistical significance between the groups was noticed in early and late postoperative complications. CONCLUSIONS: Whether using a laparoscopic or an open method, HR is challenging. In our study, patients who underwent LHR were associated with reduced hospital stays and faster bowel movements.

Light-chain amyloidosis with dysphagia as the main symptom: a case report.

BACKGROUND: Immunoglobulin light-chain amyloidosis is a relatively rare condition with a worldwide incidence of 5.1-12.8 cases per million person-years (Baker, 2022). It is characterized by a clonal population of immunoglobulin-secreting cells that produce a monoclonal light chain of κ or λ type as either an intact molecule or a fragment. CASE PRESENTATION: A 69-year-old East Asian (Chinese) male patient who presented with progressive dysphagia visited multiple hospitals repeatedly for more than 2 years and was finally diagnosed with immunoglobulin light-chain amyloidosis. CONCLUSIONS: Otolaryngologists should consider immunoglobulin light-chain amyloidosis when encountering suspicious clinical manifestations and intervene early to avoid misdiagnosis.

Evaluation of a new scoring system for assessing nerve invasion in resected pancreatic cancer: A single-center retrospective analysis.

Nerve invasion (NI) is a characteristic feature of pancreatic cancer. Traditional dichotomous statements on the presence of NI are unreasonable because almost all cases exhibit NI when sufficient pathological sections are examined. The critical implications of NI in pancreatic cancer highlight the need for a more effective criterion. This study included 511 patients, who were categorized into a training group and a testing group at a ratio of 7:3. According to the traditional definition, NI was observed in 91.2 % of patients using five pathological slides in our study. The prevalence of NI increased as more pathological slides were used. The criterion of 'two points of intraneural (endoneural) invasion in the case of four pathological slides' has the highest receiver operating characteristic (ROC) score. Based on this new criterion, NI was proved to be an independent prognostic factor for overall survival (OS) and disease-free survival (DFS) and was also correlated with tumor recurrence (P = 0.004). Interestingly, gemcitabine-based chemotherapy regimen is an independent favorable factor for patients with high NI. In the high NI group, patients who received a gemcitabine-based regimen exhibited a better prognosis than those who did not receive the gemcitabine-based regimen for OS (P = 0.000) and DFS (P = 0.001). In conclusion, this study establishes assessment criteria to evaluate the severity of NI in order to predict patient outcomes.

Global-local aware Heterogeneous Graph Contrastive Learning for multifaceted association prediction in miRNA-gene-disease networks.

Unraveling the intricate network of associations among microRNAs (miRNAs), genes, and diseases is pivotal for deciphering molecular mechanisms, refining disease diagnosis, and crafting targeted therapies. Computational strategies, leveraging link prediction within biological graphs, present a cost-efficient alternative to high-cost empirical assays. However, while plenty of methods excel at predicting specific associations, such as miRNA-disease associations (MDAs), miRNA-target interactions (MTIs), and disease-gene associations (DGAs), a holistic approach harnessing diverse data sources for multifaceted association prediction remains largely unexplored. The limited availability of high-quality data, as vitro experiments to comprehensively confirm associations are often expensive and time-consuming, results in a sparse and noisy heterogeneous graph, hindering an accurate prediction of these complex associations. To address this challenge, we propose a novel framework called Global-local aware Heterogeneous Graph Contrastive Learning (GlaHGCL). GlaHGCL combines global and local contrastive learning to improve node embeddings in the heterogeneous graph. In particular, global contrastive learning enhances the robustness of node embeddings against noise by aligning global representations of the original graph and its augmented counterpart. Local contrastive learning enforces representation consistency between functionally similar or connected nodes across diverse data sources, effectively leveraging data heterogeneity and mitigating the issue of data scarcity. The refined node representations are applied to downstream tasks, such as MDA, MTI, and DGA prediction. Experiments show GlaHGCL outperforming state-of-the-art methods, and case studies further demonstrate its ability to accurately uncover new associations among miRNAs, genes, and diseases. We have made the datasets and source code publicly available at https://github.com/Sue-syx/GlaHGCL.

Dislocation Effect Boosting the Electrochemical Properties of Prussian Blue Analogues for 2.6 V High-Voltage Aqueous Zinc-Based Batteries.

Prussian blue analogues (PBAs) have attracted increasing attention in aqueous zinc-based batteries (AZBs) with the advantages of an open framework, adjustable redox potential, and easy synthesis. However, they exhibited a low specific capacity and a poor cycle performance. In this work, crystalline potassium iron hexacyanoferrate (FeHCF) with dislocation was designed and prepared by a poly(vinylpyrrolidone) (PVP) additive. The metastable state provided by PVP would cause an electrostatic interaction between cyanogen and water molecules. The reduced force increases the steric resistance of the water molecules entering the crystal. The low content of crystal water in FeHCF is associated with the formation of dislocation. The dislocation effect effectively improves the electrochemical reactivity and reaction kinetics of FeHCF. Thus, it presents a high reversible capacity of 131 mAh g-1 with a superior capacity retention of 85% after 550 cycles at 0.5 A g-1. When used as a cathode, the AZBs display a high voltage of 2.6 V, a fast charging capability (<5 min), and a satisfactory cycle stability with a capacity retention of 82% after 400 cycles at 0.2 A g-1 in decoupling electrolytes. This work provides an effective strategy for the design of high-performance PBA-based cathodes for 2.6 V AZBs.

The clinicopathological significance and prognostic impact of 14-3-3σ/stratifin expression on patients with surgically resectable intrahepatic cholangiocarcinoma.

INTRODUCTION: Intrahepatic cholangiocarcinoma (iCCA) is the second most common primary liver cancer after hepatocellular carcinoma. Through data mining of publicly available iCCA transcriptomic datasets from the Gene Expression Omnibus, we identified SFN as the most significantly up-regulated gene in iCCA compared to normal tissue, focusing on the Gene Ontology term "cell proliferation" (GO:0008283). SFN encodes the 14-3-3σ protein, also known as stratifin, which plays crucial roles in various cellular processes. MATERIALS AND METHODS: Immunohistochemistry was used to assess stratifin expression in 182 patients with localized iCCAs undergoing surgical resection. Patients were divided into low and high expression groups, and the association between stratifin expression and clinicopathological features was analyzed. Univariate and multivariate survival analyses were performed to assess overall survival (OS), disease-specific survival (DSS), local recurrence-free survival (LRFS), and metastasis-free survival (MeFS). RESULTS: Elevated stratifin expression in iCCAs was significantly associated with the absence of hepatitis, positive surgical margins, advanced primary tumor stages, and higher histological grades (all p ≤ 0.011). Survival analyses demonstrated a significant negative association between stratifin expression and all prognostic indicators, including OS, DSS, LRFS, and MeFS (all p ≤ 0.0004). Multivariate analysis revealed that stratifin overexpression was significantly correlated with poorer outcomes in terms of DSS, LRFS, and MeFS (all p < 0.001). CONCLUSIONS: These findings suggest that stratifin may play a crucial role in iCCA oncogenesis and tumor progression, serving as a potential novel prognostic biomarker.

Nomogram construction and evaluation for predicting non-remission after a single radioactive iodine therapy for Graves' hyperthyroidism: a retrospective cohort study.

Background: Radioactive iodine (RAI) therapy is a widely used treatment for Graves' Hyperthyroidism (GH). However, various factors can impact the non-remission rate of GH after single RAI therapy. This study aimed to develop an online dynamic nomogram to assist physicians in providing personalized therapy for GH. Methods: Data from 454 GH patients who received RAI therapy were retrospectively reviewed and included in the present study. The univariate and multivariate analysis were conducted to investigate and identify independent influencing factors. The nomogram was developed based on the training cohort to explore non-remission rates. Finally, the reliability and accuracy of the constructed nomogram model were verified in the validation cohort via the calibration, receiver operating characteristic (ROC) curve, and decision curve analysis (DCA). Results: 24-hours radioactive iodine uptake (RAIU24h), effective half-life (Teff), total iodine dose (TID) and iodine dose per gram of thyroid tissue (IDPG) were independent predictors. The nomogram had a high C-index 0.922 (95% CI: 0.892-0.953), for predicting non-remission. The calibration curves demonstrated excellent consistency between the predicted and the actual probability of non-remission. ROC analysis showed that the AUC of the nomogram model and the four independent factors in the training cohort were 0.922, 0.673, 0.760, 0.761, and 0.786, respectively. The optimal cutoff value for the total nomogram scores was determined to be 155. A total score of ≥155 indicates a higher likelihood of non-remission after a single RAI therapy for GH, whereas a score below 155 suggests a greater likelihood of remission. Additionally, the DCA curve indicated that this nomogram had good clinical utility in predicting non-remission. Conclusion: An online nomogram was constructed with good predictive performance, which can be used as a practical approach to predict and assist physicians in making personalized therapy decisions for GH patients.
