Effect of health literacy on hospital readmission among patients with heart failure: A protocol for systematic review and meta-analysis.

BACKGROUND: Patients with heart failure have a high rate of health literacy deficiency, and their hospital readmission is a great burden. Whether health literacy affects hospital readmission remains controversial. OBJECTIVE: To investigate the impact of health literacy on hospital readmission among heart failure patients. METHOD: Relevant keywords were used to search for Chinese and English literature from Web of Science, PubMed, Cochrane Library, China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals, Digital Journal of Wanfang Data, and Chinese BioMedical Literature Database. Newcastle-Ottawa Scale was used to assess the quality of the studies. Statistical analysis was performed using Stata 15.0, the fixed effect model was used to calculate the pooled effect estimate, and Begg's and Egger's tests were applied to assess the presence of publication bias. RESULTS: Nine studies, involving 4093 heart failure patients, were included in this study. The overall rate of inadequate health literacy was 40.3%. Among these articles, 6 were included in the meta-analysis to calculate the pooled effect. The results indicated that, when compared with patients with adequate health literacy, those with inadequate health literacy had a relative risk of hospital readmission of 1.01, which increased to 1.14 after adjusting for follow-up time, the result was not significant (P = .09). CONCLUSIONS: About 2 out of 5 heart failure patients had inadequate health literacy, and there was no statistical association between health literacy and hospital readmission among these patients. This finding should be carefully considered and confirmed in further studies.

Distinct pathway activities are associated with prognosis and response to bortezomib-containing treatment in MCL1-M based molecular subtypes of multiple myeloma.

Multiple myeloma (MM) is the second most prevalent hematological malignancy and remains incurable with remarkable heterogeneity in prognosis and treatment response across the patients. Clinical diagnosis and the existing molecular classification systems are inadequate for predicting treatment responses. Based on the convergence between plasma cell development and MM pathogenesis, we identified a gene co-expression module centered on the plasma cell survival regulator MCL1 (MCL1 module, MCL1-M) in the transcriptomes of pre-treated MM, which enabled stratification of MM patients into MCL1-M high and MCL1-M low molecular subtypes with subtype-specific prognosis and response to bortezomib-containing treatment. Here, we aimed to examine the mechanism underlying the disparate prognosis and treatment responses between the two molecular subtypes. Our findings reveal that MCL1-M high MM displays significant activation of pathways associated with cell proliferation, while MCL1-M low MM exhibits activation of immune-related signaling pathways. The relative enrichment of immune cells within the bone marrow microenvironment of MCL1-M low MM, particularly plasmacytoid dendritic cells, likely contributes to the activation of immune-related signaling pathways in this subset of myeloma cells. Using phase III trial data, we show that responses to bortezomib-containing treatment are associated with the extent of unfolded protein response (UPR) signaling activity. Further, bortezomib-mediated killing of MM cells could be enhanced or inhibited by in vitro manipulation of UPR activities in representative cell lines. In conclusion, MCL1-M based molecular subtypes of MM are characterized by distinct signaling activities from both malignant cells and bone marrow microenvironment, which may drive distinct prognosis and treatment responses.

Men with a history of commercial heterosexual contact play essential roles in the transmission of HIV-1 CRF55_01B from men who have sex with men to the general population in Guangxi, China.

Background: There is increasing focus on HIV-1 CRF55_01B in China. However, there is limited information regarding the dissemination of CRF55_01B across different regions and populations in Guangxi. This study was performed to elucidate the evolutionary history of the introduction and dissemination of CRF55_01B in Guangxi. Methods: Molecular network and phylogenetic analyses were used to investigate the transmission characteristics of CRF55_01B in China. The analyses particularly focused on the cross-provincial spatial and temporal transmission patterns between Guangdong Province and Guangxi, as well as the transmission dynamics among different regions and populations within Guangxi. Results: In total, 2226 partial pol sequences of CRF55_01B strains sampled from 2007 to 2022 were collected, including 1895 (85.09%) sequences from Guangdong, 199 (8.94%) sequences from Guangxi, and 172 (7.59%) sequences from other provinces of China. Most people living with HIV in Guangxi were infected with HIV-1 through heterosexuals (52.76%). Among these, 19.10% had a history of commercial heterosexual contact (CHC) and 15.58% had a history of non-marital non-commercial heterosexual contact (NMNCHC). Overall, 1418 sequences were identified in the molecular network. Notably, the sequences from Guangdong Province were most closely linked to those from Guangxi. Phylogenetic analysis showed that CRF55_01B was first introduced from Shenzhen City to Nanning City around 2007. Subsequently, CRF55_01B established local transmission within Guangxi, with Nanning City serving as the transmission center from 2008 to 2017. After 2017, the CRF55_01B strain spread to other regions of Guangxi. Men who have sex with men (MSM) and men with a history of CHC have played a significant role in the transmission of CRF55_01B among different populations in Guangxi. Conclusions: This study provides evidence on the transmission trajectory of CRF55_01B among different regions and populations in Guangxi. Given the bridging role of men with a history of CHC in the dissemination of CRF55_01B from MSM to the general population, it is imperative to enhance surveillance among key populations to mitigate the secondary transmission of HIV-1.

Spotlight on endoplasmic reticulum stress in acute kidney injury: A bibliometric analysis and visualization from 1997 to 2024.

BACKGROUND: Endoplasmic reticulum (ER) stress, a protective stress response of body and play important role in maintain ER stability. Acute kidney injury (AKI) is a severe syndrome, and the molecular mechanisms of AKI has not been fully elucidated. With an increasing understanding of ER stress, ER stress has been investigated and considered a potential and novel therapeutic target in AKI. This study aims to employ a bibliometric approach to analyze research trends and focal points in ER stress associated with AKI over 3 decades. METHODS: Data were retrieved from the Web of Science Core Collection on April 15, 2024. CiteSpace and VOSviewer bibliometric software were mainly used to measure bibliometrics and analyze knowledge graphs to predict the latest research trends in the field. RESULTS: There were 452 "ER stress in AKI" articles in the Web of Science Core Collection. According to the report, China and the United States were the leading research drivers in this field. Central South University was the most active academic institution, contributing the most documents. In this field, Dong Zheng was the most prolific author. The American Journal of Physiology-Renal Physiology was the journal with the most records among all journals. The keywords "NLRP3 inflammasome," "redox signaling," and novel forms of cell death such as "ferroptosis" may represent current research trends and directions. CONCLUSION: The bibliometric analysis comprehensively examines the trends and hotspots on "ER stress and AKI." Studies on AKI related to stress in the ER are still in their infancy. Research should focus on understanding the relationship between ER stress and inflammasome, redox signal pathways and new forms of cell death such as ferroptosis.

The role of ALDH2 rs671 polymorphism and C-reactive protein in the phenotypes of male ALS patients.

Background: The aldehyde dehydrogenase 2 (ALDH2) rs671 (A) allele has been implicated in neurodegeneration, potentially through oxidative and inflammatory pathways. The study aims to investigate the effects of the ALDH2 rs671 (A) allele and high sensitivity C-reactive protein (hs-CRP) on the clinical phenotypes of amyotrophic lateral sclerosis (ALS) in male and female patients. Methods: Clinical data and ALDH2 rs671 genotype of 143 ALS patients, including 85 males and 58 females, were collected from January 2018 to December 2022. All patients underwent assessment using the Chinese version of the Edinburgh Cognitive and Behavioral ALS Screen (ECAS). Complete blood count and metabolic profiles were measured. Clinical and laboratory parameters were compared between carriers and non-carriers of the rs671 (A) allele in males and females, respectively. The significant parameters and rs671 (A) Allele were included in multivariate linear regression models to identify potential contributors to motor and cognitive impairment. Mediation analysis was employed to evaluate any mediation effects. Results: Male patients carrying rs671 (A) allele exhibited higher levels of hs-CRP than non-carriers (1.70 mg/L vs. 0.50 mg/L, p = 0.006). The rs671 (A) allele was identified as an independent risk factor for faster disease progression only in male patients (ß = 0.274, 95% CI = 0.048-0.499, p = 0.018). The effect of the rs671 (A) allele on the executive function in male patients was fully mediated by hs-CRP (Indirect effect = -1.790, 95% CI = -4.555--0.225). No effects of the rs671 (A) allele or hs-CRP were observed in female ALS patients. The effects of the ALDH2 rs671 (A) allele and the mediating role of hs-CRP in male patients remained significant in the sensitivity analyses. Conclusion: The ALDH2 rs671 (A) allele contributed to faster disease progression and hs-CRP mediated cognitive impairment in male ALS patients.

Synergic treatment of domestic wastewater and food waste in an anaerobic membrane bioreactor demo plant: Process performance, energy consumption, and greenhouse gas emissions.

Ambient operation and large-scale demonstration have limited the implementation and evaluation of anaerobic membrane bioreactors (AnMBRs) for low-strength wastewater treatment. Here, we studied these issues at an AnMBR demo plant that treats domestic wastewater and food waste together at ambient temperatures (7-28 °C). At varied hydraulic retention times (HRTs, 8-42 h), the AnMBR achieved a COD removal efficiency and biogas production of 80.4% ± 3.9% and 66.5 ± 9.4 NL/m3-Influent, respectively. Moreover, a stable high membrane flux of 14.4 L/m2/h was reached. The electric energy consumption for the AnMBR operation was 0.269-0.433 kW·h/m3, and 49.4%-91.3% could be compensated by the electric energy produced from methane production. At an HRT of 10 h, the AnMBR system demonstrated an impressively low net electric energy consumption of merely 0.05 kW·h/m3, resulting in a net greenhouse gas emission of 0.015 CO2-eq/m3, cutting 85% compared to the conventional activated sludge process. Achievements in this study provide key parameters for the ambient operation of AnMBR and demonstrate that AnMBR is an energy-saving and low-carbon solution for low-strength wastewater treatment.

A 12-year comparison of patients with Alzheimer's dementia with their informants in eight Asian countries.

BACKGROUND: The number of patients with Alzheimer's disease (AD) has increased dramatically in Asia. OBJECTIVE: To update the demographic characteristics of patients with AD and their informants in eight Asian countries and compare them from 12 years prior. METHODS: The A1-A3 components of the Uniform Dataset (UDS), version 3.0, were administered in Taiwan, Beijing, Hong Kong, Korea, Japan, Philippines, Thailand, and Indonesia. Data were compared with patients with AD in the first registration using the UDS version 1.0 from 2010-2014 in the same regions. RESULTS: A total of 1885 patients with AD and their informants were recruited from 2022 to 2024 and were compared with 2042 patients recruited a decade prior. Each country had its own unique characteristics that changed between both eras. The mean age of the patients and informants was 79.8±8.2 years and 56.5±12.1 years, respectively. Compared with the first registration, the patients were older (79.8 vs 79.0, p=0.002) and had worse global function (mean CDR-SB scores 6.1 vs 5.8, p<0.001); more informants were children (56 % vs. 48 %, p<0.001), and their frequency of in-person visits increased significantly if not living together. A total of 11 %, 4.5 %, 11 %, and 0.4 % of the patients had a reported history of cognitive impairment in their mothers, fathers, siblings, and children, respectively; all percentages, except children, increased significantly over the past decade. CONCLUSION: The present study reports the heterogeneous characteristics of patients with AD and their informants in Asian countries, and the distinct changes in the past decade. The differences in dementia evaluation and care between developing and developed countries warrant further investigation.

Multi-dimensional signals coupling of simultaneous acquisition stripping current with laser-induced breakdown spectroscopy for accurate analysis of Cd(II) in coexisting Cu(II).

BACKGROUND: Despite significant advancements in detecting Cd(II) using nanomaterials-modified sensitive interfaces, most detection methods rely solely on a single electrochemical stripping current to indicate concentration. This approach often overlooks potential inaccuracies caused by interference from coexisting ions. Therefore, establishing multi-dimensional signals that accurately reflect Cd(II) concentration in solution is crucial. RESULTS: In this study, we developed a system integrating concentration, electrochemical stripping current, and laser-induced breakdown spectroscopy (LIBS) characteristic peak intensity through in-situ laser-induced breakdown spectroscopy and electrochemical integrated devices. By simultaneously acquiring multi-dimensional signals to dynamically track the electrochemical deposition and stripping processes, we observed that replacement reactions occur between Cu(II) and Cd(II) on the surface of Ru-doped MoS2 modified carbon paper electrodes (Ru-MoS2/CP). These reactions facilitate the oxidation of Cd(0) to Cd(II) during the stripping process, significantly increasing the currents of Cd(II). Remarkably, the ingenious design of the Ru-MoS2 sensitive interface allowed for the undisturbed deposition of Cu(II) and Cd(II) during the electrochemical deposition process. Consequently, our in-situ integrated device achieved accurate detection of Cd(II) in complex environments, boasting a detection sensitivity of 8606.5 counts µM⁻1. SIGNIFICANCE: By coupling multi-dimensional signals from stripping current and LIBS spectra, we revealed the interference process between Cu(II) and Cd(II), providing valuable insights for accurate electrochemical analysis of heavy metal ions in complex water environments.

Impact of shared decision-making in Taiwanese patients with atrial fibrillation eligible for novel oral anticoagulant therapy.

BACKGROUND/PURPOSE: Shared decision-making (SDM) promotes patient awareness about medical conditions and treatments, facilitating patient involvement in care decisions. This two-stage multicenter study evaluated impacts of SDM in Taiwanese adults with atrial fibrillation (AF) eligible for novel oral anticoagulant (NOAC) therapy. METHODS: Participants were NOAC-naïve (part I) or dabigatran-experienced (part II). During Stage I, part I participants (n = 124) completed a semi-structured survey (understanding evaluation sections only) before and after viewing SDM materials on stroke prevention for AF. Surveys collected data on anxiety about AF, confidence in healthcare professionals, usefulness of the SDM materials, and perception of different NOACs. During Stage II, part I participants after being prescribed NOACs, and part II participants completed another survey to compare impacts of SDM. RESULTS: During Stage I, dabigatran was the preferred NOAC after viewing the SDM materials among 90% of part I participants. During Stage II, both part I (n = 87) and part II participants (n = 104) completed another survey. Fewer part I participants were anxious about AF (p < 0.01), and more had confidence in healthcare professionals (p < 0.01) after viewing SDM materials than before. Most part I participants (≥90%) rated the SDM materials as "very helpful". In Stage II, participants viewing SDM before initiating dabigatran had lower anxiety (part I, 43%; part II, 53%; p < 0.01) and a higher trust (part I, 92%; part II, 84%; p < 0.01). CONCLUSION: In conclusion, SDM reduced anxiety and improved trust in healthcare professionals among NOAC-naïve participants with AF.

Designing electrolytes with high solubility of sulfides/disulfides for high-energy-density and low-cost K-Na/S batteries.

Alkaline metal sulfur (AMS) batteries offer a promising solution for grid-level energy storage due to their low cost and long cycle life. However, the formation of solid compounds such as M2S2 and M2S (M = Na, K) during cycling limits their performance. Here we unveil intermediate-temperature K-Na/S batteries utilizing advanced electrolytes that dissolve all polysulfides and sulfides (K2Sx, x = 1-8), significantly enhancing reaction kinetics, specific capacity, and energy density. These batteries achieve near-theoretical capacity (1655 mAh g-1 sulfur) at 75 °C with a 1 M sulfur concentration. At a 4 M sulfur concentration, they deliver 830 mAh g-1 at 2 mA cm-2, retaining 71% capacity after 1000 cycles. This new K-Na/S battery with specific energy of 150-250 Wh kg-1 only employs earth-abundant elements, making it attractive for long-duration energy storage.

Injectable Gel-PEG hydrogels as promising delivery system for intravitreal PACAP release: Novel therapeutics for unilateral common carotid artery occlusion induced retinal ischemia.

Retinal ischemia is an ophthalmic emergency often caused by cardiovascular diseases, leading to irreversible vision loss and even blindness. Innovative retinal ischemia treatments are needed due to limited options. The pathological mechanisms involve retinal cell apoptosis and microglial activation. The pituitary adenylate cyclase-activating polypeptide (PACAP) is a well distributed neuropeptide found in both central nervous system and peripheral organs. Though it shows great anti-apoptosis and anti-microglia activation properties, it is rapidly cleared by intravitreal injection. Herein, we established a novel poly(ethylene glycol) (PEG) hydrogel system by cross-linking 4arm-PEG-NHS and 4arm-PEG-NH2 to load PACAP (PACAP@Gel-PEG), which exhibited great fluidity, injectability, structural recovery ability, moderate swelling ratio and drug release ability that were appropriate for drug delivery. Then the safety and effectiveness of the PACAP@Gel-PEG were evaluated in vitro in three retinal cell lines (ARPE-19, 661 W and rRMC) and in vivo using the unilateral common carotid artery occlusion (UCCAO) mice model. The CCK-8 test and live/dead staining demonstrated that PACAP@Gel-PEG exhibited excellent biocompatibility in three retinal cell lines. Furthermore, after PACAP@Gel-PEG treatment, a great anti-apoptotic effect was observed in cells treated by CoCl2. Application of PACAP@Gel-PEG greatly improved the therapeutic efficacy of PACAP in restoring retinal function, maintaining retinal integrity, and suppressing apoptosis and microglia activation in retinal tissues. Moreover, in mice, the biosafety of PACAP@Gel-PEG was confirmed by H&E staining of systemic organs. Taken together, our results demonstrated PACAP@Gel-PEG as a promising therapeutic option for retinal ischemia, providing new strategies for vision restoration.

Complete mitochondrial genomes of Dactylogyrus crucifer and Dactylogyrus zandti reveal distinct patterns of codon usage within Dactylogyrus.

Monogeneans of the genus Dactylogyrus Diesing, 1850, the largest genus in the family Dactylogyridae, mostly parasitize the gills of cyprinoid hosts; however, only 3 Dactylogyrus' mitochondrial genomes (mitogenomes) are studied so far. The aim of this research is to extend our understanding of the mitogenomes of Dactylogyrus. We sequenced the mitogenomes of D. crucifer and D. zandti isolated from Rutilus rutilus and Abramis brama orientalis in northwest China, and then we compared these mitogenomes with other monogeneans. We used Illumina NovaSeq to sequence the entire mitochondrial genomes of D. crucifer and D. zandti and characterized the mitogenomes to understand the gene structure, gene identity, the secondary structures of the 22 tRNA genes, and relative synonymous codon usage. We used the analytic Bayesian Information and Maximum Likelihood methods to determine their associated phylogenetic trees. The mitogenomes of D. crucifer and D. zandti were 14,403 and 18,584 bp, respectively. Organization and positioning of these genes were in accordance with Dactylogyrus lamellatus and Dactylogyrus tuba. The nucleotide composition of Dactylogyridae was different from other families of Monogenea, and the A+T count of genus Dactylogyrus (54 - 58.4 %) was lower than other genus species of the family Dactylogyridea (63.9 - 78.4 %) in protein-coding genes. Dactylogyrus members displayed a codon usage bias. The relative synonymous codon used by Dactylogyrus was not conserved and was lower than other monogeneans. The codon use patterns of closely-related species isolated from closely-related hosts were identical. Phylogenetic analyses using mitogenomic dataset produced Dactylogyrus isolated from host subfamily Leuciscinae formed a sister-group. Our results contributed significantly to an increased database of mitogenomes, more than 50 %, for Dactylogyrus that may help future studies of mitochondrial genes and codon uses for the analysis of monogenean phylogenetics.

Interactions of clathrate hydrate promoters sodium dodecyl sulfate and tetrahydrofuran investigated using 1H diffusion nuclear magnetic resonance at hydrate-forming conditions.

Thermodynamic hydrate promoters and kinetic hydrate promoters can be used to reduce the P-T conditions for clathrate hydrate synthesis to decrease the nucleation induction time while increasing growth rates. Two commonly used promoters for hydrate research are tetrahydrofuran (THF) and sodium dodecyl sulfate (SDS), which can increase the overall hydrate promotion when used in tandem as compared to individually. There are several molecular theories regarding how SDS promotes hydrate growth. This study explores the micellular theory, for which hydrate formation depends on surfactant aggregates (micelles) at a critical micelle concentration (CMC) to increase the interfacial surface area. The micellular theory is the most investigated and criticized surfactant hydrate promotion theory. To address questions related to micellar behavior, this study investigates the intermolecular behavior between SDS and THF for the identification of micelles at hydrate-forming conditions. The systems explored contained THF at 3 and 5 wt. % with varying concentrations of SDS below and above the CMC. Several methods including a qualitative visual method, conductivity, interfacial tensiometry, 13C Liquid-state Nuclear Magnetic Resonance (NMR) spectroscopy, and 1H diffusion NMR spectroscopy were evaluated at temperatures below the Krafft point of SDS and above 0 °C. The presence of THF at low concentrations decreased the critical temperature for the formation of SDS micelles, where SDS is solubilized in THF/water solution at hydrate-forming temperatures without precipitation. The CMC of SDS was decreased significantly even at hydrate-forming conditions. Mixed surfactant-cosolvent micellular behavior of SDS in the presence of low concentrations of THF was confirmed at hydrate-forming conditions above 0 °C.

Multicenter investigation of preoperative distinction between primary central nervous system lymphomas and glioblastomas through interpretable artificial intelligence models.

OBJECTIVE: Research into the effectiveness and applicability of deep learning, radiomics, and their integrated models based on Magnetic Resonance Imaging (MRI) for preoperative differentiation between Primary Central Nervous System Lymphoma (PCNSL) and Glioblastoma (GBM), along with an exploration of the interpretability of these models. MATERIALS AND METHODS: A retrospective analysis was performed on MRI images and clinical data from 261 patients across two medical centers. The data were split into a training set (n = 153, medical center 1) and an external test set (n = 108, medical center 2). Radiomic features were extracted using Pyradiomics to build the Radiomics Model. Deep learning networks, including the transformer-based MobileVIT Model and Convolutional Neural Networks (CNN) based ConvNeXt Model, were trained separately. By applying the "late fusion" theory, the radiomics model and deep learning model were fused to produce the optimal Max-Fusion Model. Additionally, Shapley Additive exPlanations (SHAP) and Grad-CAM were employed for interpretability analysis. RESULTS: In the external test set, the Radiomics Model achieved an Area under the receiver operating characteristic curve (AUC) of 0.86, the MobileVIT Model had an AUC of 0.91, the ConvNeXt Model demonstrated an AUC of 0.89, and the Max-Fusion Model showed an AUC of 0.92. The Delong test revealed a significant difference in AUC between the Max-Fusion Model and the Radiomics Model (P = 0.02). CONCLUSION: The Max-Fusion Model, combining different models, presents superior performance in distinguishing PCNSL and GBM, highlighting the effectiveness of model fusion for enhanced decision-making in medical applications. CLINICAL RELEVANCE STATEMENT: The preoperative non-invasive differentiation between PCNSL and GBM assists clinicians in selecting appropriate treatment regimens and clinical management strategies.

The efficacy and safety of continuous theta burst stimulation for auditory hallucinations: a systematic review and meta-analysis of randomized controlled trials.

Objective: Auditory hallucinations are the most frequently occurring psychotic symptom in schizophrenia. Continuous theta burst stimulation (cTBS) has been used as an adjuvant treatment for auditory hallucinations. This meta-analysis focused on randomized controlled clinical trials (RCTs) to assess the efficacy of adjuvant cTBS on auditory hallucinations in schizophrenia. Methods: We performed a comprehensive search of four international databases from their inception to January 14, 2024, to identify relevant RCTs that assessed the effects of adjuvant cTBS on auditory hallucinations. The key words included "auditory hallucinations", "continuous theta burst stimulation" and "transcranial magnetic stimulation". Inclusion criteria included patients with auditory hallucinations in schizophrenia or schizoaffective disorder. The Revised Cochrane risk-of-bias tool for randomized trials (RoB1) were used to evaluate the risk of bias and the Review Manager Software Version 5.4 was employed to pool the data. Results: A total of 4 RCTs involving 151 patients with auditory hallucinations were included in the analysis. The Cochrane risk of bias of these studies presented "low risk" in all items. Preliminary analysis showed no significant advantage of adjuvant cTBS over sham stimulation in reducing hallucinations [4 RCTs, n = 151; SMD: -0.45 (95%CI: -1.01, 0.12), P = 0.13; I2 = 61%]. Subgroup analysis revealed that patients treated with adjuvant cTBS for more than 10 stimulation sessions and total number of pulses more than 6000 [3 RCTs, n = 87; SMD: -4.43 (95%CI: -8.22, -0.63), P = 0.02; I2 = 47%] had a statistically significant improvement in hallucination symptoms. Moreover, the rates of adverse events and discontinuation did not show any significant difference between the cTBS and sham group. Conclusions: Although preliminary analysis did not revealed a significant advantage of adjuvant cTBS over sham stimulation, subgroup analysis showed that specific parameters of cTBS appear to be effective in the treatment of auditory hallucinations in schizophrenia. Further large-scale studies are needed to determine the standard protocol of cTBS for treating auditory hallucinations.

Psychometric properties of International Trauma Questionnaire (ITQ) and symptom structure of complex post-traumatic stress disorder among Chinese patients with MDD.

AIMS: To assess the validity and internal reliability of the International Trauma Questionnaire (ITQ) among patients diagnosed with major depressive disorder (MDD) and to explore the network structure of Complex post-traumatic stress disorder (CPTSD) among MDD patients in China. METHODS: Eligible individuals were recruited from a large tertiary hospital in Guangdong Province. Trained researchers conducted in-person interviews and administered self-report questionnaires, including demographics, medical information, and psychological assessments. Confirmatory factor analyses (CFA) and network analysis were performed, with calculations of Average Variance Extracted (AVE), Cronbach's α, and composite reliability. RESULTS: A total of 113 patients with MDD participated in this study. The correlated six-factor one-order model was a good representation of the latent structure of ITQ (χ2= 60.114, df = 39, P = 0.017, SRMR = 0.070, RMSEA = 0.050, TLI = 0.952, CFI = 0.972, BIC = 175.508). All ITQ subscales possessed acceptable convergent validity and internal reliability, except for affective dysregulation and re-experiencing. The square root of AVE for affective dysregulation was lower than its correlations with other clusters. Network analysis revealed that node C4 ('I feel worthless'), as a core symptom, was significantly associated with the development of CPTSD. CONCLUSIONS: The clinical applicability of the ITQ was demonstrated by its overall validity and reliability among patients with MDD. However, the affective dysregulation and re-experiencing clusters still need to be revised and enhanced. Timely screening, recognition, and diagnosis are critical due to the worse clinical outcomes seen in comorbid patients.

A nebular origin for the persistent radio emission of fast radio bursts.

Fast radio bursts (FRBs) are millisecond-duration, bright (approximately Jy) extragalactic bursts, whose production mechanism is still unclear1. Recently, two repeating FRBs were found to have a physically associated persistent radio source of non-thermal origin2,3. These two FRBs have unusually large Faraday rotation measure values2,3, probably tracing a dense magneto-ionic medium, consistent with synchrotron radiation originating from a nebula surrounding the FRB source4-8. Recent theoretical arguments predict that, if the observed Faraday rotation measure mostly arises from the persistent radio source region, there should be a simple relation between the persistent radio source luminosity and the rotation measure itself7,9. Here we report the detection of a third, less luminous persistent radio source associated with the repeating FRB source FRB 20201124A at a distance of 413 Mpc, substantially expanding the predicted relation into the low luminosity-low Faraday rotation measure regime (<1,000 rad m-2). At lower values of the Faraday rotation measure, the expected radio luminosity falls below the limit-of-detection threshold for present-day radio telescopes. These findings support the idea that the persistent radio sources observed so far are generated by a nebula in the FRB environment and that FRBs with low Faraday rotation measure may not show a persistent radio source because of a weaker magneto-ionic medium. This is generally consistent with models invoking a young magnetar as the central engine of the FRB, in which the surrounding ionized nebula-or the interacting shock in a binary system-powers the persistent radio source.

Notch1 signaling pathway promotes growth and metastasis of gastric cancer via modulating CDH5.

OBJECTIVE: To explore the underlying molecular mechanism of Notch1/cadherin 5 (CDH5) pathway in modulating in cell malignant behaviors of gastric cancer (GC). METHODS: We performed bioinformatic analyses to screen the potential target genes of Notch1 from cadherins in GC. Western blot and RT-PCR were conducted to detect CDH5 expression in GC tissues and cells. We utilized chromatin immunoprecipitation (CHIP) assays to assess the interaction of Notch1 with CDH5 gene. The effects of Notch1/CDH5 axis on the proliferation, invasion, migration and vasculogenic mimicry in GC cells were evaluated by EdU, wound healing, transwell, and tubule formation assays. RESULTS: Significantly increased CDH5 expression was found in GC tissues compared with paracancerous tissues and associated to clinical stage and poor overall survival (OS) in patients with GC. Notch1 positively regulate the expression of CDH5 in GC cells. CHIP assays validated that CDH5 was a direct target of Notch1. In addition, Notch1 upregulation enhanced the proliferation, migration, invasion and vasculogenic mimicry capacity of GC cells, which could be attenuated by CDH5 silencing. CONCLUSIONS: These results indicated Notch1 upregulation enhanced GC malignant behaviors by triggering CDH5, suggesting that targeting Notch1/CDH5 axis could be a potential therapeutic strategy for GC progression.

π-π conjugated PDI supramolecular regulating the photoluminescence of imine-COFs for sensitive smartphone visual detection of levofloxacin.

As the contamination and enrichment in food chain of levofloxacin (LV) antibiotics have caused a significant threat to life safety, the instant detection of LV has become an urgent need. Here, a PDI-functionalized imine-based covalent organic framework (PDI-COF300) was prepared by the electrostatic self-assembly method as fluorescent probe for smartphone visual detection of LV, which exhibited excellent fluorescence quantum yield (82.68%), greater stability, high sensitivity with detection limit of 0.303 µM. Based on the results of molecular docking and Stern-Volmer equation, the LV detection by PDI-COF300 was mainly a static quenching process through π-π stacked hydrophobic interactions and fluorescence resonance energy transfer. Besides, PDI-COF300 was applied to LV detection in environmental medium and milk samples with recoveries from 85.56% to 108.34% and relative standard deviations <2.70%. This work also provided a new general strategy for using PDI-COF in smartphone devices and fluorescent papers for LV fluorescence detection and microanalysis.

PathEX: Make good choice for whole slide image extraction.

BACKGROUND: The tile-based approach has been widely used for slide-level predictions in whole slide image (WSI) analysis. However, the irregular shapes and variable dimensions of tumor regions pose challenges for the process. To address this issue, we proposed PathEX, a framework that integrates intersection over tile (IoT) and background over tile (BoT) algorithms to extract tile images around boundaries of annotated regions while excluding the blank tile images within these regions. METHODS: We developed PathEX, which incorporated IoT and BoT into tile extraction, for training a classification model in CAM (239 WSIs) and PAIP (40 WSIs) datasets. By adjusting the IoT and BoT parameters, we generated eight training sets and corresponding models for each dataset. The performance of PathEX was assessed on the testing set comprising 13,076 tile images from 48 WSIs of CAM dataset and 6,391 tile images from 10 WSIs of PAIP dataset. RESULTS: PathEX could extract tile images around boundaries of annotated region differently by adjusting the IoT parameter, while exclusion of blank tile images within annotated regions achieved by setting the BoT parameter. As adjusting IoT from 0.1 to 1.0, and 1-BoT from 0.0 to 0.5, we got 8 train sets. Experimentation revealed that set C demonstrates potential as the most optimal candidate. Nevertheless, a combination of IoT values ranging from 0.2 to 0.5 and 1-BoT values ranging from 0.2 to 0.5 also yielded favorable outcomes. CONCLUSIONS: In this study, we proposed PathEX, a framework that integrates IoT and BoT algorithms for tile image extraction at the boundaries of annotated regions while excluding blank tiles within these regions. Researchers can conveniently set the thresholds for IoT and BoT to facilitate tile image extraction in their own studies. The insights gained from this research provide valuable guidance for tile image extraction in digital pathology applications.
