Intestinal microbiota and gene expression alterations in leopard coral grouper (Plectropomus leopardus) under enteritis.

Enteritis poses a significant threat to fish farming, characterized by symptoms of intestinal and hepatic inflammation, physiological dysfunction, and dysbiosis. Focused on the leopard coral grouper (Plectropomus leopardus) with an enteritis outbreak on a South China Sea farm, our prior scrutiny did not find any abnormalities in feeding or conventional water quality factors, nor were any specific pathogen infections related to enteritis identified. This study further elucidates their intestinal flora alterations, host responses, and their interactions to uncover the underlying pathogenetic mechanisms and facilitate effective prevention and management strategies. Enteritis-affected fish exhibited substantial differences in intestinal flora compared to control fish (P = 0.001). Notably, norank_f_Alcaligenaceae, which has a negative impact on fish health, predominated in enteritis-affected fish (91.76 %), while the probiotic genus Lactococcus dominated in controls (93.90 %). Additionally, certain genera with pathogenesis potentials like Achromobacter, Sphingomonas, and Streptococcus were more abundant in diseased fish, whereas Enterococcus and Clostridium_sensu_stricto with probiotic potentials were enriched in control fish. At the transcriptomic level, strong inflammatory responses, accompanied by impaired metabolic functions, tissue damage, and iron death signaling activation were observed in the intestines and liver during enteritis. Furthermore, correlation analysis highlighted that potential pathogen groups were positively associated with inflammation and tissue damage genes while presenting negatively correlated with metabolic function-related genes. In conclusion, dysbiosis in the intestinal microbiome, particularly an aberrantly high abundance of Alcaligenaceae with pathogenic potential may be the main trigger for this enteritis outbreak. Alcaligenaceae alongside Achromobacter, Sphingomonas, and Streptococcus emerged as biomarkers for enteritis, whereas some species of Lactococcus, Clostridium_sensu_stricto, and Enterococcus showed promise as probiotics to alleviate enteritis symptoms. These findings enhance our understanding of enteritis pathogenesis, highlight intestinal microbiota shifts in leopard coral grouper, and propose biomarkers for monitoring, probiotic selection, and enteritis management.

Mediating Role of Rumination in Second Victim Experience to Turnover Intention in Psychiatric Nurses.

BACKGROUND: Psychiatric nurses often face patient safety incidents that can cause physical and emotional harm, even leading to s econd victim syndrome and staff shortages. Rumination-a common response after nurses suffer a patient safety event-may play a specific role between the second victim experience and turnover intention. Understanding these mechanisms is crucial for supporting psychiatric nurses and retaining psychiatric nursing resources. OBJECTIVES: The study aimed to explore the associations among second victim experience, rumination, and turnover intention in psychiatric nurses and confirm how second victim experience influences turnover intention through rumination and its subtypes. METHODS: A descriptive, cross-sectional study was adapted to survey 252 psychiatric nurses who experienced a patient safety incident at three hospitals in China between March and April 2023. We used the Sociodemographic and Patient Safety Incident Characteristics Questionnaire (the Chinese version of the Second Victim Experience and Support Tool), the Event-Related Rumination Inventory, and the Turnover Intention Scale. Path analysis with bootstrapping was employed to accurately analyze and estimate relationships among the study variables. RESULTS: There was a positive association between second victim experience and turnover intention. In addition, both invasive and deliberate rumination showed significant associations with second victim experience and turnover intention. Notably, our results revealed that invasive and deliberate rumination played partial mediating roles in the relationship between second victim experience and turnover intention in psychiatric nurses. DISCUSSION: The negative experience and turnover intention of the psychiatric nurse second victims are at a high level. Our results showed that invasive rumination positively mediated the relationship between second victim experience and turnover intention, and deliberate rumination could weaken this effect. This study expands the knowledge of the mechanisms underlying the effect of the second victim experience on turnover intention. Organizations must attach importance to the professional dilemmas of the psychiatric nurses' second victims. Nurse managers can reduce nurses' turnover intention by taking measures to reduce invasive rumination and fostering deliberate meditation to help second victims recover from negative experiences.

Conservative Scattering of Spinning Black Holes at Fourth Post-Minkowskian Order.

Using the N=1 supersymmetric, spinning worldline quantum field theory formalism, we compute the conservative spin-orbit part of the momentum impulse Δp_{i}^{µ}, spin kick ΔS_{i}^{µ}, and scattering angle θ from the scattering of two spinning massive bodies (black holes or neutron stars) up to fourth post-Minkowskian (PM) order. These three-loop results extend the state of the art for generically spinning binaries from 3PM to 4PM. They are obtained by employing recursion relations for the integrand construction and advanced multiloop Feynman integral technology in the causal (in-in) worldline quantum field theory framework to directly produce classical observables. We focus on the conservative contribution (including tail effects) and outline the computations for the dissipative contributions as well. Our spin-orbit results agree with next-to-next-to-next-to-leading-order post-Newtonian and test-body data in the respective limits. We also reconfirm the conservative 4PM nonspinning results.

C1QTNF6 regulated by miR-29a-3p promotes proliferation and migration in stage I lung adenocarcinoma.

OBJECTIVE: C1QTNF6 has been implicated as an essential component in multiple cellular and molecular preliminary event, including inflammation, glucose metabolism, endothelial cell modulation and carcinogenesis. However, the biological process and potential mechanism of C1QTNF6 in lung adenocarcinoma (LUAD) are indefinite and remain to be elucidated. Therefore, we investigated the interaction among the traits of C1QTNF6 and LUAD pathologic process. METHODS: RT-qPCR and western blot were conducted to determine the expression levels of C1QTNF6. RNA interference and overexpression of C1QTNF6 were constructed to identify the biological function of C1QTNF6 in cellular proliferative, migratory and invasive potentials in vitro. Dual-luciferase reporter assay was applied to identify the possible interaction between C1QTNF6 and miR-29a-3p. Moreover, RNA sequencing analysis of C1QTNF6 knockdown was performed to identify the potential regulatory pathways. RESULTS: C1QTNF6 was upregulated in stage I LUAD tissues compared with adjacent non-cancerous tissues. Concurrently, C1QTNF6 knockdown could remarkably inhibit cell proliferation, migratory and invasive abilities, while overexpression of C1QTNF6 presented opposite results. Additionally, miR-29a-3p may serve as an upstream regulator of C1QTNF6 and reduce the expression of C1QTNF6. Subsequent experiments showed that miR-29a-3p could decrease the cell mobility and proliferation positive cell rates, as well as reduce the migratory and invasive possibilities in LUAD cells via downregulating C1QTNF6. Moreover, RNA sequencing analysis demonstrated that the cytokine-cytokine receptor interaction pathway may participate in the process of C1QTNF6 regulating tumor progression. CONCLUSION: Our study first demonstrated that downregulation of C1QTNF6 could inhibit tumorigenesis and progression in LUAD cells negatively regulated by miR-29a-3p. These consequences could reinforce our awareness and understanding of the underlying mechanism and provide a promising therapeutic target for LUAD.

An integrated analysis of the competing endogenous RNA network associated of prognosis of stage I lung adenocarcinoma.

BACKGROUND: Accumulating evidence indicates that long non-coding RNAs (lncRNAs) are involving in the tumorigenesis and metastasis of lung cancer. The aim of the study is to systematically characterize the lncRNA-associated competing endogenous RNA (ceRNA) network and identify key lncRNAs in the development of stage I lung adenocarcinoma (LUAD). METHODS: Totally, 1,955 DEmRNAs, 165 DEmiRNAs and 1,107 DElncRNAs were obtained in 10 paired normal and LUAD tissues. And a total of 8,912 paired lncRNA-miRNA-mRNA network was constructed. Using the Cancer Genome Atlas (TCGA) dataset, the module of ME turquoise was revealed to be most relevant to the progression of LUAD though Weighted Gene Co-expression Network Analysis (WGCNA). RESULTS: Of the lncRNAs identified, LINC00639, RP4-676L2.1 and FENDRR were in ceRNA network established by our RNA-sequencing dataset. Using univariate Cox regression analysis, FENDRR was a risk factor of progression free survival (PFS) of stage I LUAD patients (HRs = 1.69, 95%CI 1.07-2.68, P < .050). Subsequently, diffe rential expression of FENDRR in paired normal and LUAD tissues was detected significant by real-time quantitative (qRT-PCR) (P < 0.001). CONCLUSIONS: This study, for the first time, deciphered the regulatory role of FENDRR/miR-6815-5p axis in the progression of early-stage LUAD, which is needed to be established in vitro and in vivo.

Comprehensive Analysis of Aquaporin Superfamily in Lung Adenocarcinoma.

Background: Lung adenocarcinoma (LUAD) is the most predomintnt lung cancer subtype with increasing morbidity and mortality. Previous studies have shown that aquaporin (AQP) family genes were correlated with tumor progression and metastasis in several kinds of malignancies. However, their biological behaviors and prognostic values in LUAD have not been comprehensively elucidated. Methods: RNA sequencing and real-time reverse transcription PCR (RT-PCR) were used to assess AQP1/3/4/5 gene expressions in LUAD patients using GEPIA and UALCAN databases. And then Kaplan-Meier analysis, cBioPortal, Metascape, GeneMANIA, TISIDB, and TIMER were utilized to determine the prognostic value, mutation frequency, and immune cell infiltration of AQP family members in LUAD. Results: We found that AQP3 expression was significantly elevated and AQP1 expression was markedly reduced in LUAD patients, whereas the expression levels of AQP4 and AQP5 exhibited no significant changes. The Kaplan-Meier survival analysis indicated that the higher expressions of AQP1/4/5 were related to longer overall survival (OS). Of interest, AQP3 was significantly correlated with the clinical tumor stage and lower AQP3 expression showed favorable prognosis in stage I LUAD patients, which indicated that AQP3 may be a potential prognostic biomarker for patients. Through functional enrichment analysis, the functions of these four AQPs genes were mainly involved in the passive transport by aquaporins, water homeostasis, and protein tetramerization. Moreover, AQP1/3/4/5 expression was strongly associated with tumor-infiltrating lymphocytes (TILs) in LUAD. Conclusion: AQP3 can be used as a prognosis and survival biomarker for stage I LUAD. These findings may provide novel insights into developing molecular targeted therapies in LUAD.

Clinical Study on Effect of Solution Focused Approach on the Complications, Pain, Sleep, and Quality of Life in Patients with Hepatocellular Carcinoma Undergoing TACE.

OBJECTIVE: The objective of this study is to explore the effect of solution focused approach (SFA) on the complications, pain, sleep, and quality of life in patients with hepatocellular carcinoma undergoing transcatheter arterial chemoembolization (TACE). METHODS: Total of 106 patients with hepatocellular carcinoma who underwent TACE in our hospital from July 2019 to June 2020 were selected. According to the admission time, they were divided into the control group (n = 53) and the observation group (n = 53). The control group implemented routine nursing intervention, and the observation group implemented SFA on the basis of the control group. The clinical data, complications, pain, sleep status, and quality of life scores were compared between the two groups. RESULTS: The total incidence of complications in the observation group (16.98%) was lower than that in the control group (33.96%) (P < 0.05). There was no significant difference in the score of pain perception between the two groups (P > 0.05). The scores of sleep status in the observation group were lower than those in the control group (P < 0.05). The quality of life scores in the observation group was higher than that in the control group (P < 0.05). CONCLUSION: SFA can effectively reduce the complications, relieve pain, improve sleep status, and improve the quality of life in patients with hepatocellular carcinoma undergoing TACE.

The association between the incidence risk of pneumonitis and PD-1/PD-L1 inhibitors in advanced NSCLC: A meta-analysis of randomized controlled trials.

OBJECTIVE: Immune checkpoint inhibitors (ICIs) have shown a significant efficacy for patients with non-small cell lung cancer (NSCLC). However, checkpoint inhibitor pneumonitis (CIP) is a rare but severe and life-threatening adverse event. Hence, we performed a systematic review and meta-analysis to evaluate the incidence and risk of CIP in patients with NSCLC. METHODS: Pubmed, Embase, Cochrane Library and ClinicalTrials.gov (http://clinicaltrials.gov/) were searched up to December 15, 2020. Studies regarding all-grade and high-grade pneumonitis were included. The data was analyzed using meta-packages of R 3.6.0. RESULTS: A total of sixteen randomized controlled trials including 9500 patients were identified for further evaluation. The overall incidence of all-grade and high-grade CIP was 4.17% and 2.02%, respectively. Compared with conventional chemotherapy, patients treated with ICIs significantly increased risk of all-grade (RR: 4.11, p < 0.0001) and high-grade (RR: 3.16, p < 0.0001) pneumonitis. Subgroup analysis showed the ICIs combined with chemotherapy was associated with a higher incidence of CIP than monotherapy alone (6.03% vs 3.32%, p = 0.01). And the rate of death owing to CIP was higher than chemotherapy-mediated pneumonitis. CONCLUSION: There were a higher incidence and risk of pneumonitis with the application of ICIs when compared with chemotherapy. Higher mortality rate of pneumonitis was more frequent in ICIs group. Thus, early detection, proper administration and optimal management are needed for physicians prevent potentially CIP deterioration.

Single-vesicle tracking reveals the potential correlation of the movement of cell-bound membrane vesicles (CBMVs) with cell migration.

The movement of cell-bound membrane vesicles (CBMVs) on migrating cells is poorly understood. We hypothesized that the movement of CBMVs on migrating cells is different from that on non-migrating cells and can be interfered by external stimuli. To test it, single-vesicle tracking was performed to analyze motion type, speed, displacement, and direction of CBMVs on migrating cells treated with different reagents (Ang-1, TNF-α, LPS, VEGFα, endostatin, Cytochalasin D, and nocodazole) among which the former four promoted cell migration whereas the others inhibited cell migration. We found that cell migration changed CBMVs from non-directed to directed motion and that most CBMVs on untreated migrating cells moved along the migration axis. Interestingly, the migration-promoting reagents played positive roles in CBMV movement (improving directed motion, speed and/or maximal displacement, upregulating the amount of vesicles moving in migration direction) whereas the migration-inhibiting reagents played negative roles (impairing/abolishing directed motion, speed and/or maximal displacement, downregulating the vesicles moving forward or causing an even distribution of motion direction). The cytoskeleton (particularly microtubules) probably played vital roles in CBMV movement on migrating cells and mediated the effects of stimuli on vesicle movement. The data may provide important information for understanding the properties, behaviors, and functions of CBMVs.
