Recent years have witnessed exponential growth in cardiac imaging technologies, allowing better visualization of complex cardiac anatomy and improved assessment of physiology. These advances have become increasingly important as more complex surgical and catheter-based procedures are evolving to address the needs of a growing congenital heart disease population. This state-of-the-art review presents advances in echocardiography, cardiac magnetic resonance, cardiac computed tomography, invasive angiography, 3-dimensional modeling, and digital twin technology. The paper also highlights the integration of artificial intelligence with imaging technology. While some techniques are in their infancy and need further refinement, others have found their way into clinical workflow at well-resourced centers. Studies to evaluate the clinical value and cost-effectiveness of these techniques are needed. For techniques that enhance the value of care for congenital heart disease patients, resources will need to be allocated for education and training to promote widespread implementation.

Abstract The vertebrate stress response (SR) is mediated by the hypothalamic–pituitary–adrenal (HPA) axis and contributes to generating context appropriate physiological and behavioral changes. Although the HPA axis plays vital roles both in stressful and basal conditions, research has focused on the response under stress. To understand broader roles of the HPA axis in a changing environment, we characterized an adaptive behavior of larval zebrafish during ambient illumination changes. Genetic abrogation of glucocorticoid receptor (nr3c1) decreased basal locomotor activity in light and darkness. Some key HPI axis receptors (mc2r [ACTH receptor], nr3c1), but not nr3c2 (mineralocorticoid receptor), were required to adapt to light more efficiently but became dispensable when longer illumination was provided. Such light adaptation was more efficient in dimmer light. Our findings show that the HPI axis contributes to the SR, facilitating the phasic response and maintaining an adapted basal state, and that certain adaptations occur without HPI axis activity.

The participants were enrolled and an electronic questionnaire was exclusively sent to the members of the Lung Cancer Special Committee of the China Medicine Education Association through the WeChat platform. Multivariable logistic regression analysis was performed to explore the associated factors of high PR knowledge scores (≥ 18 points).Results: From the 858 valid questionnaires, the routine implementation of PR was only reported for 16.95% of physicians. The main reason hindering the implementation of PR for patients was the limited knowledge and awareness of PR among the physicians involved (69.1%). A total of 618 and 240 physicians had high and low knowledge scores, respectively. Multivariable analysis suggests that the self-perception of PR knowledge (OR = 1.89, 95% CI: 1.32– 2.771, P = 0.001) was independently associated with high knowledge scores, while having no theoretical knowledge of PR was associated with poor knowledge scores (OR = 0.43, 95% CI: 0.26– 0.72, P = 0.001).Conclusion: Inadequate knowledge of pulmonary rehabilitation is evident among physicians who are involved in pulmonary disease management in China. This underscores the need for more comprehensive and standardized training to bolster their awareness and effective utilization of pulmonary rehabilitation.Keywords: chronic obstructive pulmonary disease, pulmonary rehabilitation, lung cancer, knowledge, oncologists

Data on the number of patients with COPD in China from 1990 to 2019 were obtained from the Global Burden of Disease (GBD) database. The coefficient of determination (R2), mean absolute error (MAE), mean absolute percentage error (MAPE), root mean squared error (RMSE), relative error of prediction, Akaike Information Criterion (AIC), and Bayesian Information Criterion (BIC) were used to evaluate and compare the fitting effect, prediction effect, and reliability of the three models.Results: The GAM, ARIMA, and curve-fitting methods could predict future trends in COPD in China. The performance of the GAM is the best among the three models, whereas the curve fitting method is the worst, and the ARIMA (0,1,2) model is in between. The prediction results of the three models showed that the number of patients with COPD in China is expected to increase from 2020 to 2025.Conclusion: GAM and AIRMA models are recommended for predicting the future prevalence of COPD in China. The number of patients with COPD in China is expected to increase in the next few years. The prevention and control of COPD in China still needs to be strengthened. Using appropriate models to predict future trends in COPD will provide support for health policymakers.Keywords: generalized additive model, ARIMA model, curve fitting method, COPD, prediction

Clinical, demographic, and concomitant medication data were collected. The endpoint was defined as OAC discontinuation for more than 30 days or a switch to an alternative therapy. Predictors of OAC non-persistence were investigated using a multivariable Cox regression model.Results: This study included 560 participants (51.1% men, mean age 80.9± 0.2 years). During a median follow-up of 20 months, medication persistence was observed in 322 patients (57.5%). Non-persistence was found to be significantly higher with warfarin than with NOAC (48.8% vs 33.6%, p = 0.006). In the multivariate analysis, OAC non-persistence was independently predicted by a history of permanent pacemaker implantation, the use of antiplatelet drugs, employee Medicare, living with children, college degree or above, and persistent AF (HR = 1.580, 1.586, 0.604, 0.668, 0.028, 0.769, p < 0.05, respectively). Treatment discontinuation within 3 months of discharge was observed in a large number of patients (81.8%). Medication discontinuation due to bleeding was more frequently observed in patients who continued for longer than 3 months (p < 0.001), while discontinuation due to patient preference was more frequent in those with shorter durations (≤ 3 months) (p = 0.049). Patient preference was the second leading cause of non-persistence in patients, regardless of whether they were taking warfarin or NOAC.Conclusion: OAC non-persistence remains high among elderly AF patients during long-term follow-up, with a significant proportion discontinuing shortly after discharge. This pattern of non-persistence is heavily influenced by demographic factors and patient preference. Further interventions should be developed based on the reasons and risk factors to improve persistence and initiated early in the treatment process.Keywords: atrial fibrillation, the elderly, oral anticoagulants, non-persistence

However, the molecular mechanism underlying lipid metabolism in esophageal squamous cell carcinoma (ESCC) and its effect on patient prognosis are not well understood. The objective of our study was to construct a lipid metabolism-related prognostic model to improve prognosis prediction in ESCC.Methods: We downloaded the mRNA expression profiles and corresponding survival data of patients with ESCC from the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) databases. We performed differential expression analysis to identify differentially expressed lipid metabolism-related genes (DELMGs). We used Univariate Cox regression and least absolute shrinkage and selection operator (LASSO) analyses to establish a risk model in the GEO cohort and used data of patients with ESCC from the TCGA cohort for validation. We also explored the relationship between the risk model and the immune microenvironment via infiltrated immune cells and immune checkpoints.Results: The result showed that 132 unique DELMGs distinguished patients with ESCC from the controls. We identified four genes (ACAA1, ACOT11, B4GALNT1, and DDHD1) as prognostic gene expression signatures to construct a risk model. Patients were classified into high- and low-risk groups as per the signature-based risk score. We used the receiver operating characteristic (ROC) curve and the Kaplan-Meier (KM) survival analysis to validate the predictive performance of the 4-gene signature in both the training and validation sets. Infiltrated immune cells and immune checkpoints indicated a difference in the immune status between the two risk groups.Conclusion: The results of our study indicated that a prognostic model based on the 4-gene signature related to lipid metabolism was useful for the prediction of prognosis in patients with ESCC.Keywords: biomarkers, esophageal squamous cell carcinoma, immune microenvironment, lipid metabolism, prognosis

Predicting poorly differentiated HCC has essential significance for clinical decision-making. Although some studies have developed predictive models based on magnetic resonance imaging (MRI) and radiomics, radiomic features that require specific software for analysis are impractical for clinical work. This study aims to develop a novel and user-friendly nomogram model to predict E-S grade III–IV.Patients and Methods: Medical data on patients meeting the inclusion criteria were obtained from the Nanjing Drum Tower Hospital HCC database (January 2020 to December 2022). Univariate analysis was used to screen for risk factors associated with E-S grade III–IV. A novel nomogram was established based on the subsequent multivariate logistic regression analysis. The performance of the established model was evaluated through diagnostic ability, calibration, and clinical benefits.Results: Overall, 240 HCC patients were included in this study. Among them, 103 were highly differentiated (E-S grade I–II) HCC and 137 were poorly differentiated (E-S grade III–IV) HCC. A nomogram model that integrated alpha-fetoprotein (AFP), des-γ-carboxy prothrombin (DCP), hepatitis B virus surface antigen (HBsAg), hepatitis C virus antibodies (HCVAb), aspartate aminotransferase to lymphocyte ratio index (ALRI), and macrovascular invasion was established. The novel model had a good diagnostic performance with an area under the curve (AUC) value of 0.763. Meanwhile, the model had a diagnostic accuracy of 72.5%, a sensitivity of 78.1%, and a specificity of 65.1%. The calibration curve showed good calibration of the nomogram model (mean absolute error = 0.043), and the decision curve analysis (DCA) demonstrated that the clinical benefit was provided.Conclusion: Our developed nomogram model could successfully predict E-S grade III–IV in HCC patients, which may be helpful in clinical decision-making.Keywords: hepatocellular carcinoma, Edmondson-Steiner grade, nomogram, prediction

In China, the COVID-19 epidemic situation entered a low level now. With the arrival of flu season, the number of patients with respiratory symptoms is increasing. We reported three cases of patients who co-infected with SARS-CoV-2 and influenza A virus (IAV), and they were all treated with nirmatrelvir-ritonavir (NMV/r) and baloxavir marboxil. Due to the overlapping clinical features between the two diseases, it is important to identified them and gave the antiviral therapy timely.Keywords: COVID-19, influenza, co-infection, baloxavir marboxil, nirmatrelvir-ritonavir

For the particularity of the COVID-19 medical images with blurred boundaries, low contrast and different infection sites, some researchers have improved the accuracy by adding more complexity. Also, they overlook the complexity of lesions, which hinder their ability to capture the relationship between segmentation sites and the background, as well as the edge contours and global context. However, increasing the computational complexity, parameters and inference speed is unfavorable for model transfer from laboratory to clinic. A perfect segmentation network needs to balance the above three factors completely. To solve the above issues, this paper propose a symmetric automatic segmentation framework named MS-DCANet. We introduce Tokenized MLP block, a novel attention scheme that uses a shift-window mechanism to conditionally fuse local and global features to get more continuous boundaries and spatial positioning capabilities. It has greater understanding of irregular lesion contours. MS-DCANet also uses several Dual Channel blocks and a Res-ASPP block to improve the ability to recognize small targets. On multi-modality COVID-19 tasks, MS-DCANet achieved state-of-the-art performance compared with other baselines. It can well trade off the accuracy and complexity. To prove the strong generalization ability of our proposed model, we apply it to other tasks (ISIC 2018 and BAA) and achieve satisfactory results.Patients: The X-ray dataset from Qatar University which contains 3379 cases for light, normal and heavy COVID-19 lung infection. The CT dataset contains the scans of 10 patient cases with COVID-19, a total of 1562 CT axial slices. The BAA dataset is obtained from the hospital and includes 387 original images. The ISIC 2018 dataset is from the International Skin Imaging Collaborative (ISIC) containing 2594 original images.Results: The proposed MS-DCANet achieved evaluation metrics (MIOU) of 73.86, 97.26, 89.54, and 79.54 on the four datasets, respectively, far exceeding other current state-of-the art baselines.Conclusion: The proposed MS-DCANet can help clinicians to automate the diagnosis of COVID-19 patients with different symptoms.Keywords: multi-modality COVID-19 lesion segmentations, laboratory to clinic, multi-scale feature learning, depthwise separable convolution

Another cohort was enrolled for external validation. The area under the curve (AUC) of receiver operating characteristic (ROC) was calculated to evaluate the accuracy of the model.Results: A total of 1493 eligible patients with AMI were enrolled as the training set, of whom 70 (4.7%) developed VA during hospitalization. In-hospital mortality was significantly higher in the VA set than in the non-VA set (31.4% vs 2.7%, P=0.001). The independent predictors of VA in patients with AMI including Killip grade ≥ 3, STEMI patients, LVEF < 50%, frequent premature ventricular beats, serum potassium < 3.5 mmol/L, type 2 diabetes, and creatinine level. The AUC of the model for predicting VT/VF in the training set was 0.815 (95% CI: 0.763– 0.866). A total of 1149 cases were enrolled from Xuzhou Center Hospital as the external validation set. The AUC of the model in the external validation set for predicting VT/VF was 0.755 (95% CI: 0.687– 0.823). Calibration curves indicated a good consistency between the predicted and the observed probabilities of VA in both sets.Conclusion: We have established a clinical prediction risk score for predicting the occurrence of VA in AMI patients. The prediction score is easy to use, performs well and can be used to guide clinical practice.Keywords: ventricular tachycardia, ventricular flutter and fibrillation, risk stratification, scoring system, acute myocardial infarction

Our previous Phase III clinical study revealed that polymeric micellar paclitaxel (Pm-Pac) is safe and efficacious in advanced NSCLC patients. However, the histopathological-toxicological profile of Pm-Pac in mammals remains unclear.Methods: We examined the Pm-Pac-induced antitumour effect in both A549/H226 cells and A549/H226-derived xenograft tumour models.. And then, we evaluated the short-term and long-term toxicity induced by Pm-Pac in healthy Sprague‒Dawley (SD) rats. The changes in body weight, survival, peripheral neuropathy, haematology, and histopathology were studied in SD rats administered Pm-Pac at different dosages.Results: In the A549-derived xenograft tumour model, better therapeutic efficacy was observed in the Pm-Pac group than in the solvent-based paclitaxel (Sb-Pac) group when an equal dosage of paclitaxel was administered. Toxicity assessments in healthy SD rats indicated that Pm-Pac caused toxicity at an approximately 2- to 3-fold greater dose than Sb-Pac when examining animal body weight, survival, peripheral neuropathy, haematology, and histopathology. Interestingly, based on histopathological examinations, we found that Pm-Pac could significantly decrease the incidences of paclitaxel-induced brain and liver injury but could potentially increase the prevalence of paclitaxel-induced male genital system toxicity.Conclusion: This study introduces the toxicological profile of the engineered nanoparticle Pm-Pac and provides a novel perspective on the Pm-Pac-induced histopathological-toxicological profile in a rat model.Graphical Abstract: Keywords: nanomedicine, polymeric micellar paclitaxel, NSCLC, toxicological profile

Dynamic Nuclear Polarization (DNP) is a powerful suite of techniques that deliver multifold signal enhancements in nuclear magnetic resonance (NMR) and MRI. The generated athermal spin states can also be exploited for quantum sensing and as probes for many-body physics. Typical DNP methods require the use of cryogens, large magnetic fields, and high power microwave excitation, which are expensive and unwieldy. Nanodiamond particles, rich in Nitrogen-Vacancy (NV) centers, have attracted attention as alternative DNP agents because they can potentially be optically hyperpolarized at room temperature. Here, unraveling new physics underlying an optical DNP mechanism first introduced by Ajoy et al. [Sci. Adv. 4, eaar5492 (2018)], we report the realization of a miniature "optical nanodiamond hyperpolarizer," where 13C nuclei within the diamond particles are hyperpolarized via the NV centers. The device occupies a compact footprint and operates at room temperature. Instrumental requirements are very modest: low polarizing fields, low optical and microwave irradiation powers, and convenient frequency ranges that enable miniaturization. We obtain the best reported optical 13C hyperpolarization in diamond particles exceeding 720 times of the thermal 7 T value (0.86% bulk polarization), corresponding to a ten-million-fold gain in averaging time to detect them by NMR. In addition, the hyperpolarization signal can be background-suppressed by over two-orders of magnitude, retained for multiple-minute long periods at low fields, and deployed efficiently even to 13C enriched particles. Besides applications in quantum sensing and bright-contrast MRI imaging, this work opens possibilities for low-cost room-temperature DNP platforms that relay the 13C polarization to liquids in contact with the high surface-area particles.

The origins of spin lifetimes in quantum systems is a matter of importance in several areas of quantum information. Spectrally mapping spin relaxation processes provides insight into their origin and motivates methods to mitigate them. In this paper, we map nuclear relaxation in a prototypical system of [Formula: see text] nuclei in diamond coupled to Nitrogen Vacancy (NV) centers over a wide field range (1 mT-7 T). Nuclear hyperpolarization through optically pumped NV electrons allows signal measurement savings exceeding million-fold over conventional methods. Through a systematic study with varying substitutional electron (P1 center) and [Formula: see text] concentrations, we identify the operational relaxation channels for the nuclei at different fields as well as the dominant role played by [Formula: see text] coupling to the interacting P1 electronic spin bath. These results motivate quantum control techniques for dissipation engineering to boost spin lifetimes in diamond, with applications including engineered quantum memories and hyperpolarized [Formula: see text] imaging.

The purpose of this study was to construct an age-related specific immune index according to the immune aging phenomenon of gastric cancer (GC) and explore its prognostic value.Methods: This study retrospectively analyzed patients who underwent radical GC surgery in the Department of Gastrointestinal Surgery, Affiliated Cancer Hospital of Harbin Medical University, from August 2014 to December 2016 and divided them into a training cohort and a validation cohort. A new immune score, the GC-specific immune index (GSII), was developed as a series of lymphocyte subsets associated with the prognosis of patients with GC. Then, the receiver operating characteristic (ROC) curve was used to compare the prediction performance. The Kaplan‒Meier method and Log rank test were used to analyze the overall survival of patients. Cox hazard regression models were used to identify independent risk factors associated with prognosis. Finally, a nomogram model was constructed by combining the GSII and clinicopathological characteristics, and the calibration chart, consistency index, and decision curve were used to test the performance of the model.Results: Aging did not significantly affect CD8 cell counts but decreased CD4 and CD19 cell counts. Based on the Cox analysis, the GSII of patients ≤ 60 years old was 0.079×lg CD4+0.348×lg CD19, and the GSII of patients > 60 years old was 0.058×lg CD4. A decreased GSII was indicative of a poor prognosis and was an independent risk factor associated with patient outcomes. The nomogram constructed based on the GSII and clinicopathological features accurately predicted patient prognosis. Furthermore, the GSII was well validated in the validation cohort.Conclusion: The GSII constructed for the special immune aging phenomenon of GC can accurately predict patient prognosis.Keywords: gastric cancer, lymphocyte subsets, age, prognosis

Inadequate postoperative analgesia usually leads to severe postsurgical pain, which could cause patients to suffer from many other related complications. Recently, an increasing number of studies have found that gabapentin can relieve hyperalgesia, postoperative pain, and postoperative inflammation. However, there have been no reports on the use of gabapentin combined with sufentanil preoperatively for acute pain following intraspinal tumor resection.Study Design and Methods: This is a protocol for a randomized, placebo-controlled, and double-blinded trial. One-hundred and sixty-eight participants with chronic pain related to the intraspinal tumor will be randomized into the gabapentin and placebo groups in a 1:1 ratio. In the gabapentin group, patients will be given 300 mg gabapentin orally 36 h, 24 h, and 12 h before surgery; the placebo group will receive a placebo orally at the same time points preoperatively. To estimate the efficacy and safety endpoints, all the researchers and patients will be blinded until the completion of this study. The primary outcome will be the consumption of sufentanil within 48 h postoperatively. The secondary outcomes include the visual analog scale pain score and Von Frey mechanical pain threshold 36 h and 24 h before and 24 h and 48 h after surgery, the incidence of postoperative nausea, vomiting, and drowsiness, the length of hospital stay and medical expenses.Discussion: This trial is to evaluate the efficacy and safety of gabapentin combined with sufentanil for postoperative analgesia in patients who complain of pain before intraspinal tumor resection. The findings will provide a new strategy for multimode perioperative analgesia management in these patients.Keywords: gabapentin, intraspinal tumor resection, multimode perioperative analgesia, opiates
