The effectiveness of Balint groups at improving empathy in medical and nursing education: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: Empathy is crucial for patient health. The Balint group is a commonly used method for empathy training. However, the impact of Balint groups on empathy remains unclear. This systematic review and meta-analysis of randomized controlled trials (RCTs) aims to assess the impact of Balint groups on empathy training among medical and nursing students, as well as doctors and nurses. METHODS: This review involved searching multiple databases for relevant articles. Rigorous eligibility criteria were applied during the screening of titles and abstracts, and during the selection of records. Following a full-text eligibility evaluation, two reviewers independently extracted data from the final selection of studies, and a meta-analysis was conducted. The standardized mean difference (SMD) was calculated to assess the systematic outcomes. RESULTS: A total of 11 studies were included in this systematic review and meta-analysis. Participants in Balint groups demonstrated a significant increase in empathy than those in the control group (SMD = 1.46, 95% confidence interval [CI] 0.86-2.06; p < 0.001). Studies conducted in China (SMD = 2.13, 95% CI 1.27-2.99; p < 0.001) revealed a greater impact of Balint groups on empathy than those conducted in France (SMD = 0.24, 95% CI 0.12-0.37; p < 0.001). The impact of Balint groups was significantly greater among physicians (SMD = 2.50, 95% CI 1.79-3.21; p < 0.001) and nurses (SMD = 2.88, 95% CI 1.34-4.43; p < 0.001) compared to medical students (SMD = 0.71, 95% CI = 0.35-1.06; p < 0.001). Participants who attended ten or more sessions (SMD = 2.37, 95% CI 1.35-3.39; p < 0.001) demonstrated better outcomes compared to those who attended fewer than ten sessions (SMD = 0.79, 95% CI 0.30-1.29; p < 0.01). CONCLUSION: Balint groups are effective for empathy training among doctors, nurses, and medical students. Future research should incorporate patient-led measurements to evaluate empathy and ascertain the long-term impact of Balint groups on empathy training.

Rotational stability of plate-haptic toric intraocular lenses implantation with a capsular tension ring: a prospective randomized paired-eye study.

PURPOSE: To compare the rotational stability and visual outcomes of plate-haptic toric intraocular lenses (IOLs) with and without a capsular tension ring (CTR) in paired eyes. SETTING: Eye and Ears, Nose, and Throat Hospital of Fudan University, Shanghai, China. DESIGN: Prospective, randomized, paired-eye study. METHODS: Patients with bilateral cataracts and coexisting regular corneal astigmatism were enrolled. The two eyes of each patient were randomly assigned to the CTR or non-CTR (NCTR) group. Both eyes of each patient were subjected to phacoemulsification and toric IOL implantation. CTRs were implanted into the eyes of the CTR group. All patients were followed-up for 12 months; the uncorrected distance visual acuity (UDVA), residual astigmatism (RAS), and rotational degree of the toric IOL were recorded. RESULTS: In total, 186 eyes of 93 patients were eligible for analysis. At each visit, UDVA improved significantly after surgery in all eyes (p < 0.001). The mean rotational degree and RAS were significantly smaller in the CTR group at the 2-week visit (p < 0.05). The toric IOLs achieved rotational stability at 1 week postoperatively in the CTR group while at 2 weeks postoperatively in the NCTR group. In the subgroup analyses, CTR co-implantation significantly reduced the 2-week IOL rotation in eyes meeting specific ocular measurements. CONCLUSIONS: CTR co-implantation could increase the rotational stability of plate-haptic toric IOLs, by reducing the amount of the IOL rotation in the early postoperative period and accelerating the stabilization of IOLs in the capsular bag.

Vinpocetine protects against osteoarthritis by inhibiting ferroptosis and extracellular matrix degradation via activation of the Nrf2/GPX4 pathway.

BACKGROUND: Osteoarthritis (OA) is a progressive joint condition marked by the slow degradation of articular cartilage. Vinpocetine (Vin), a synthetic derivative of vincamine derived from the vinca plant, exhibits anti-inflammatory and antioxidant properties. Nevertheless, the specific role and mechanism of Vin in the treatment of OA remain largely unexplored. OBJECTIVES: The study is designed to uncover the impacts of Vin on tert­butyl hydroperoxide (TBHP)-induced ferroptosis and to explore its potential role and underlying mechanisms in the treatment of OA. Concurrently, we established an OA mouse model through medial meniscal instability surgery to assess the therapeutic effects of Vin in vivo. METHODS: Through network pharmacology analysis, we have identified the key targets and potential pathways of Vin. To simulate an oxidative stress-induced OA environment in vitro, we induced chondrocyte injury using TBHP. We tested how Vin affects chondrocytes under TBHP induction by DHE and DCFH-DA probes, BODIPY-C11 and FerroOrange staining, mitochondrial function assessment, Western blotting, co-immunoprecipitation, and immunofluorescence techniques. Simultaneously, we established an OA mouse model through medial meniscal instability surgery to assess the in vivo therapeutic effects of Vin. In this model, we used X-ray and micro-CT imaging, SO staining, TB staining, H&E staining, and immunohistochemistry to analyze the role of Vin in detail. RESULTS: This study demonstrated that Vin effectively suppressed TBHP-induced ferroptosis and extracellular matrix (ECM) degradation and significantly lessened mitochondrial damage associated with ferroptosis. In the OA mouse model, Vin improved cartilage degeneration, subchondral remodeling, synovitis, and ECM degradation. Vin worked by activating the Nrf2/GPX4 pathway and inhibiting the Keap1-Nrf2 interaction. This study focused on the function of ferroptosis in OA and its influence on chondrocyte damage and disease progression, offering novel perspectives on potential treatments. CONCLUSION: Vin activated the Nrf2/GPX4 pathway, thereby slowing OA progression, inhibiting ferroptosis, and preventing ECM degradation.

Transdermal buprenorphine patch as an adjunct to multimodal analgesia after total joint arthroplasty: a retrospective cohort study.

Background: Total hip arthroplasty or total knee arthroplasty (THA/TKA) is often associated with varying degrees of pain. In recent years, transdermal buprenorphine (TDB) patch has shown encouraging results for acute postoperative pain control in orthopedic surgery. The aim of our study was to investigate the efficacy and safety of the combination of TDB patch and nonsteroidal anti-inflammatory drugs (NSAIDs) as a multimodal analgesic regimen after THA/TKA. Methods: Patients who underwent THA and TKA between January 2022 and January 2023 were reviewed. Three postoperative analgesic regimens were selected: Group A (flurbiprofen 50 mg and tramadol 37.5 mg/acetaminophen 325 mg), Group B (flurbiprofen 50 mg and TDB 5 mg), and Group C (Parecoxib 40 mg and TDB 5 mg). The primary outcomes were the Wong-Baker face pain scale revision (FPS-R) scores and the rate of sleep disturbances. Secondary outcomes of the study included the proportion of patients with postoperative pain relief rates categorized as 0%, <50%, ≥50%, and 100%. Results: The dynamic FPS-R pain scores on day 3 after surgery in Group B were significantly lower than those in Group A for THA (P < 0.017). The dynamic FPS-R pain scores were lowest in Group C on day 2 and 3 after THA and TKA (P < 0.017). Rate of sleep disturbances was significantly lower in Group B for THA and in Group C for TKA, respectively, compared with that in Group A (P < 0.017). The proportion of dynamic pain relief rate ≥50% in Group C was statistically higher than that in Group A for THA (P < 0.017). Rate of adverse reactions among three groups for THA and TKA was not statistically different (P > 0.05). Conclusion: This study suggests that the combination of TDB patch and NSAIDs is safe and effective for postoperative analgesia after THA/TKA.

Unveiling the Network regulatory mechanism of ncRNAs on the Ferroptosis Pathway: Implications for Preeclampsia.

Non-coding RNAs (ncRNAs) are transcripts originating from the genome that do not serve as templates for protein synthesis. They function as epigenetic and translational regulators in various pathophysiological mechanisms, including cell proliferation and apoptosis. The ferroptosis signaling pathway, a novel mode of cell death, participates in numerous pathophysiological processes. Its signaling transmission is both complex and precise, featuring interconnected and interdependent pathways. Recent studies suggest that ncRNAs can finely regulate key genes in the ferroptosis pathway, thus modulating cellular functions, reducing oxidative stress, and maintaining maternal-fetal interface homeostasis. Future strategies targeting the ncRNA/ferroptosis axis may provide new perspectives and potential intervention points for treating preeclampsia. This article clarifies how the ncRNA/ferroptosis axis impacts preeclampsia, revealing how ncRNAs interact with ferroptosis, and pinpointing new molecular targets for the treatment of preeclampsia, thereby providing theoretical support for clinical strategies.

miR-16a-5p antagonizes FGF-2 in ligamentogenic differentiation of MSC: a new therapeutic perspective for tendon regeneration.

With the increasing demand for exercise, the population of patients with ankle sprain to anterior talofibular ligament injury has the characteristics of a large base and high requirements for returning to sports, and how to promote the repair of damaged ligaments from a microscopic perspective is an urgent problem to be solved. In many studies, human amniotic mesenchymal stem cells have strong differentiation ability, and can be induced to continuously differentiate into ligament cells to achieve the purpose of repairing damaged ligaments. Human amniotic stem cells were extracted and cultured from human amniotic tissues, evaluated by cell identification and other techniques, and evaluated into ligament differentiation by toluidine blue, alizarin red, oil red O staining and detection of ligament cell differentiation, protein detection by Western blot, mRNA level by qPCR, and finally, the targeted binding relationship between miR-16a-5p and mRNA FGF2 was verified by double luciferase reporter assay. The expression of collagen type 1 (COL 1), collagen type 3 (COL3), SCX and MKX was increased by overexpression of mRNA FGF2, respectively, and miR-16a-5p had a targeted effect on FGF2 and regulated the ligamentous differentiation of human amniotic mesenchymal stem cells. We found that the regulatory effect of overexpressed mRNA FGF2 on mesenchymal stem cells could be inhibited by up-regulation of miR-16a-5p, while the knockdown of FGF2 could reverse the regulatory effect of miR-16a-5p inhibition on ligament-forming differentiation of human amniotic mesenchymal stem cells. In this study, we discovered the existence of the miR-16a-5p-FGF2 axis in human amniotic mesenchymal stem cells, and the differentiation of human amniotic mesenchymal stem cells into ligamentous cells can be regulated by regulating various links in this axis.

Nurses' preferences for working in Uber-style 'Internet plus' nursing services: A discrete choice experiment.

BACKGROUND: China's 'Internet Plus' nursing services, which are Uber-style home care services with an 'online application, offline service' approach, have been evolving over the past five years. Registered nurses' preference for these Uber-style Internet Plus nursing services are crucial for improving human resource management and service efficiency, yet research in this area remains scarce. OBJECTIVE: This study aimed to explore registered nurses' preferences for Uber-style Internet Plus nursing services and provide optimization recommendations from a supply-side perspective. DESIGN: A cross-sectional study utilising a discrete choice experiment. SETTING(S): Two public tertiary hospitals located in Tianjin, China, which have implemented Internet Plus nursing services. PARTICIPANTS: 211 registered nurses who participated in Internet Plus nursing services. METHODS: The survey was conducted anonymously using an online survey platform. Respondents were presented with choices between two alternatives, based on five key attributes: income, safety and security, patient and family cooperation, commute time, and service type. Mixed logit models estimated the stated preferences for attributes. Relative importance scores, willingness-to-pay estimates, and simulations of service-type uptake rates were calculated. Subgroup analysis and seemingly unrelated regression estimation were performed to examine heterogeneity in preferences. RESULTS: A total of 3202 choice observations were generated. When sorted by the strength of preference, the five attributes related to registered nurses' choice of Uber-style Internet Plus nursing services, measured by their relative importance scores, are as follows: safety and security (30.89 %), income (27.41 %), patient and family cooperation (18.47 %), service type (11.96 %), and commuting time (11.27 %). Elevating safety and security from low to high levels has the same utility as a 31.81 % increase in monthly income, equivalent to 2586.14 yuan. Subgroup analysis showed that senior nurses place more value on safety and security than junior nurses (ß = 1.421 vs.ß = 0.725; P = 0.011), and unmarried nurses had a stronger preference for family and caregiver cooperation (ß = 1.105 vs.ß = 0.314; P = 0.023). CONCLUSIONS: The strength and heterogeneity of registered nurses' preferences should be highlighted in the dispatch algorithms model of Uber-style Internet Plus nursing services, thereby enhancing the efficiency and humanity of Uber-style Internet Plus nursing services. TWEETABLE ABSTRACT: Registered nurses prioritise safety and security, acknowledging heterogeneous preferences in Uber-style Internet Plus nursing services.

Phosphination of aryl/alkyl bromides via Mn-mediated reductive C-P coupling.

Mn-mediated reductive cross-coupling of organic bromides with 2-bromo-1,3,2-diazaphospholene was developed for efficient construction of C-P bonds under mild conditions. Mechanistic studies suggested that bromides are activated by in situ formed bis-diazaphospholene via hybrid radical and polar mechanisms.

Pyrotinib plus capecitabine for patients with HER2-positive metastatic breast cancer and brain metastases (PERMEATE trial): overall survival results from a multicenter, single-arm, two-cohort, phase 2 trial.

Background: The phase 2 PERMEATE study has shown the antitumor activity and safety of pyrotinib plus capecitabine in patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer and brain metastases. In this report, survival results were updated with extended follow-up. Methods: Between January 29, 2019 and July 10, 2020, adult patients with HER2-positive metastatic breast cancer who had radiotherapy-naïve brain metastases (cohort A, n = 59) or progressive disease after radiotherapy (cohort B, n = 19) were enrolled and received pyrotinib (400 mg once daily) and capecitabine (1000 mg/m2 twice daily on days 1-14 of each 21-day cycle) until disease progression or unacceptable toxicity. Secondary endpoints progression-free survival (PFS) and overall survival (OS) were updated, and post-hoc central nervous system (CNS)-PFS was analyzed. This study is registered with ClinicalTrials.gov (NCT03691051). Findings: As of February 2, 2023, the median follow-up duration was 30.9 months (interquartile range, 16.1-39.8). Median PFS was 10.9 months (95% confidence interval [CI], 7.6-14.6) in cohort A and 5.7 months (95% CI, 3.4-11.5) in cohort B. Median OS was 35.9 months (95% CI, 24.4-not reached) in cohort A and 30.6 months (95% CI, 12.6-33.3) in cohort B. Median CNS-PFS was 13.6 months (95% CI, 9.0-15.8) in cohort A and 5.7 months (95% CI, 3.4-11.5) in cohort B. Median OS was 34.1 months (95% CI, 21.7-not reached) for 14 patients with intracranial progression only in cohort A who restarted pyrotinib plus capecitabine after local radiotherapy. Interpretation: These data support further validation in a randomized controlled trial for the assessment of pyrotinib in combination with capecitabine as systemic therapy for patients with HER2-positive breast cancer and brain metastases.

Combining Biomarkers to Improve Diagnostic Accuracy in Detecting Diseases With Group-Tested Data.

We consider the problem of combining multiple biomarkers to improve the diagnostic accuracy of detecting a disease when only group-tested data on the disease status are available. There are several challenges in addressing this problem, including unavailable individual disease statuses, differential misclassification depending on group size and number of diseased individuals in the group, and extensive computation due to a large number of possible combinations of multiple biomarkers. To tackle these issues, we propose a pairwise model fitting approach to estimating the distribution of the optimal linear combination of biomarkers and its diagnostic accuracy under the assumption of a multivariate normal distribution. The approach is evaluated in simulation studies and applied to data on chlamydia detection and COVID-19 diagnosis.

Fam3a-mediated prohormone convertase switch in α-cells regulates pancreatic GLP-1 production in an Nr4a2-Foxa2-dependent manner.

BACKGROUND: Fam3a has been demonstrated to regulate pancreatic ß-cell function and glucose homeostasis. However, the role and mechanism of Fam3a in regulating α-cell function remain unexplored. METHODS: Glucagon and glucagon-like peptide-1 (GLP-1) levels in pancreas and plasma were measured in global Fam3a knockout (Fam3a-/-) mice. Human islet single-cell RNA sequencing (scRNA-seq) datasets were utilized to analyze gene expression correlations between FAM3A and PCSK1 (encoding PC1/3, which processes proglucagon into GLP-1). Mouse pancreatic α-cell line αTC1.9 cells were transfected with Fam3a siRNA or plasmid for Fam3a knockdown or overexpression to explore the effects of Fam3a on PC1/3 expression and GLP-1 production. The downstream mediator (including Nr4a2) was identified by transcriptomic analysis, and its role was confirmed by Fam3a knockdown or overexpression in αTC1.9 cells. Based on the interacted protein of Nr4a2 and the direct binding to Pcsk1 promoter, the transcription factor Foxa2 was selected for further verification. Nuclear translocation assay and dual-luciferase reporter assay were used to clarify the involvement of Fam3a-Nr4a2-Foxa2 pathway in PC1/3 expression and GLP-1 production. Moreover, α-cell-specific Fam3a knockout (Fam3aα-/-) mice were constructed to evaluate the metabolic variables and hormone levels under normoglycemic, high-fat diet (HFD)-fed and streptozotocin (STZ)-induced diabetic conditions. Exendin 9-39 (Ex9), a GLP-1 receptor antagonist, was used to investigate GLP-1 paracrine effects in Fam3aα-/- mice and in their primary islets. RESULTS: Compared with wild-type mice, pancreatic and plasma active GLP-1 levels were increased in Fam3a-/- mice. Analysis of human islet scRNA-seq datasets showed a significant negative correction between FAM3A and PCSK1 in α-cells. Fam3a knockdown upregulated PC1/3 expression and GLP-1 production in αTC1.9 cells, while Fam3a overexpression displayed inverse effects. Transcriptomic analysis identified Nr4a2 as a key downstream mediator of Fam3a, and Nr4a2 expression in αTC1.9 cells was downregulated and upregulated by Fam3a knockdown and overexpression, respectively. Nr4a2 silencing increased PC1/3 expression, albeit Nr4a2 did not directly bind to Pcsk1 promoter. Instead, Nr4a2 formed a complex with Foxa2 to facilitate Fam3a-mediated Foxa2 nuclear translocation. Foxa2 negatively regulated PC1/3 expression and GLP-1 production. Besides, Foxa2 inhibited the transcriptional activity of Pcsk1 promoter at specific binding sites 10 and 6, and this inhibition was intensified by Nr4a2 in αTC1.9 cells. Compared with Flox/cre littermates, improved glucose tolerance, increased active GLP-1 level in pancreas and plasma, upregulated plasma insulin level in response to glucose, and decreased plasma glucagon level were observed in Fam3aα-/- mice. Primary islets isolated from Fam3aα-/- mice also showed an increase in active GLP-1 and insulin release. In addition, the insulinotropic effect of intra-islet GLP-1 was blocked by Ex9 in Fam3aα-/- mice and in their primary islets. Similarly, HFD-fed Fam3aα-/- mice also exhibited an improved glucose tolerance. Both HFD-fed and STZ-induced diabetic Fam3aα-/- mice showed an increased pancreatic active GLP-1 level, an elevated plasma insulin level and a reduced plasma glucagon level. CONCLUSIONS: Fam3a deficiency in α-cells enhances pancreatic GLP-1 production to improve ß-cell function via paracrine signaling in an Nr4a2-Foxa2-PC1/3-dependent manner. Our study unveils a novel strategy for reprogramming α-cell proglucagon processing output from glucagon to GLP-1 and deepen the understanding of crosstalk between α-cells and ß-cells.

Life-threatening event in laparoscopic hepatic surgery: Training curriculum on sudden hepatic artery haemorrhage.

BACKGROUND: Exposure of the hepatic artery is a fundamental step in many surgeries, during which iatrogenic hepatic artery injury may occur. Although the incidence of hepatic artery haemorrhage is low, its occurrence can lead to life-threatening haemorrhage. It is difficult and dangerous to accumulate clinical experience in laparoscopic hepatic artery repair in actual patients, and simulation training models for laparoscopic hepatic artery repair are currently lacking. In this study, a 3D printed model was designed to simulate the training curriculum for sudden hepatic artery haemorrhage, but whether training with the 3D printed model could yield superior skill improvement for surgeons remained to be determined. METHODS: A new 3D printed model was designed for this study. Surgeons from the General Surgery Department of Sir Run Run Shaw Hospital participated in this simulation training. The surgical performance of each model was compared, and the authenticity of the model was evaluated and mechanically tested. RESULTS: Experienced surgeons performed better on the 3D printed model. After repeated training, inexperienced surgeons showed significant improvement of their laparoscopic hepatic artery repair skills. The authenticity of the model was generally satisfactory, but shortcomings persisted in the mechanical testing of artery wall tearing, necessitating further improvement. CONCLUSIONS: Few studies have investigated laparoscopic simulation training for sudden hepatic artery haemorrhage. This simulation model distinguishes surgeons with different levels of experience and allows those with less experience to improve their laparoscopic hepatic artery repair skills through training on the model.

Light δD apatites reveal deep origin water in North China Craton intracontinental granites and basalts.

Water is essential to the formation of intracontinental granites, but its origin remains elusive. Here we address this scientific problem by analyzing D/H isotopes of apatites, hydrous minerals in Jurassic and Early Cretaceous granites and basalts from eastern North China Craton, where water was previously interpreted as derived from subducting slab. Results reveal extremely low δD values in pristine Early Cretaceous granitic (-203‰ to -127‰) and basaltic (-197‰ to -107‰) apatites, contrasting with relatively high δD values (-137‰ to -47‰) in Jurassic granites. Given the depth-dependent D/H isotopic fractionation during slab dehydration and high-water contents in coeval primitive mafic magmas, the Early Cretaceous magma water is attributed to the stagnant slab within the mantle transition zone. Secular change in the depth of water aligns with steepening of subducting Paleo-Pacific plate from Jurassic to Early Cretaceous, demonstrating the potential of apatite H isotopes in tracing water origin in granites and basalts.

A new species of Opsariichthys (Teleostei, Cypriniformes, Xenocyprididae) from Southeast China.

Opsariichthysiridescens sp. nov. is described from the Qiantang and Oujiang rivers in Zhejiang Province and a tributary of the Yangtze River adjacent to the Qiantang River. It is distinguished from congeners by the following combination of morphological features: no obvious anterior notch on the tip of the upper lip; 45-52 lateral-line scales; 18-21 pre-dorsal scales; two rows of pharyngeal teeth; a maxillary extending to or slightly beyond the vertical anterior margin of the orbit in adult males; a pectoral fin extending to the pelvic fin in adult males; nuptial tubercles on the cheeks and lower jaw of males, which are usually united basally to form a plate; uniform narrow pale pink cross-bars on trunk and two widening significantly on caudal peduncle. Its validity was also supported by its distinct Cyt b gene sequence divergence from all congeners and its monophyly recovered in a Cyt b gene-based phylogenetic analysis.

Analgesic effect of dance movement therapy: An fNIRS study.

OBJECTIVE: This study aims to explores the physiological and psychological mechanisms of exercise-induced hypoalgesia (EIH) by combining the behavioral results with neuroimaging data on changes oxy-hemoglobin (HbO) in prefrontal cortex (PFC). METHODS: A total of 97 healthy participants were recruited and randomly divided into three groups: a single dance movement therapy (DMT) group, a double DMT group, and control group. Evaluation indicators included the pressure pain threshold (PPT) test, the color-word stroop task (CWST) for wearing functional near-infrared spectroscopy (fNIRS), and the self-assessment manikin (SAM). The testing time is before intervention, after intervention, and one hour of sit rest after intervention. RESULTS: 1) Repeated measures ANOVA revealed that, there is a time * group effect on the PPT values of the three groups of participants at three time points. After 30 min of acute dance intervention, an increase in the PPT values of 10 test points occurred in the entire body of the participants in the experimental group with a significant difference than the control group. 2) In terms of fNIRS signals, bilateral DLPFC and left VLPFC channels were significantly activated in the experimental group. 3) DMT significantly awakened participants and brought about pleasant emotions, but cognitive improvement was insignificant. 4) Mediation effect analysis found that the change in HbO concentration in DLPFC may be a mediator in predicting the degree of improvement in pressure pain threshold through dance intervention (total effect ß = 0.7140). CONCLUSION: In healthy adults, DMT can produce a diffuse EIH effect on improving pressure pain threshold, emotional experience but only showing an improvement trend in cognitive performance. Dance intervention significantly activates the left ventrolateral and bilateral dorsolateral prefrontal cortex. This study explores the central nervous system mechanism of EIH from a physiological and psychological perspective.

Socioeconomic inequalities, genetic susceptibility, and risks of depression and anxiety: A large-observational study.

OBJECTIVES: This study aimed to investigate the interplay between genetic susceptibility and socioeconomic disparities on psychiatric disorders. METHODS: In this study, we utilized data from the UK Biobank to analyze the Generalized Anxiety Disorder (GAD)-7 scale (N = 74,425) and the Patient Health Questionnaire (PHQ)-9 (N = 74,101), along with the Index of Multiple Deprivation (IMD). The polygenic risk score (PRS) was calculated to assess the genetic risk associated with GAD-7/PHQ-9 scores, and the individuals were classified into low, medium, and high genetic risk groups according to tertiles of PRSs related to the GAD-7/PHQ-9. Linear regression models were used to explore the relationships between GAD-7/PHQ-9 scores and IMD scores in patients with different genetic susceptibilities. RESULTS: Disadvantaged socioeconomic status was associated with the risk of anxiety and depression across all strata of genetic risk, and stronger associations were shown for individuals with greater genetic susceptibility. From low to high genetic risk, the risk of psychiatric disorders increased for the GAD-7 (ß = 0.002 to 0.032) and PHQ-9 (ß = 0.003 to 0.045) scores. In addition, strong associations of high genetic risk with anxiety (ß = 0.875) and depression (ß = 1.152) were detected in the IMD quartile 4 group compared with the least deprivation quartile group. Furthermore, income and employment were estimated to contribute strongly to anxiety (ßemployment = 7.331, ßincome = 4.492) and depression (ßemployment = 9.951, ßincome = 6.453) in the high genetic risk group. CONCLUSION: The results suggest that we should pay more attention to psychiatric disorders with high genetic susceptibility and try to improve their socioeconomic status to prevent the development of psychiatric disorders.

Identification of new subtypes of breast cancer based on vasculogenic mimicry related genes and a new model for predicting the prognosis of breast cancer.

Breast cancer is a malignant tumor that poses a serious threat to women's health, and vasculogenic mimicry (VM) is strongly associated with bad prognosis in breast cancer. However, the relationship between VM and immune infiltration in breast cancer and the underlying mechanisms have not been fully studied. On the basis of the Cancer Genome Atlas (TCGA), Fudan University Shanghai Cancer Center (FUSCC) database, GSCALite database, and gene set enrichment analysis (GSEA) datasets, we investigated the potential involvement of VM-related genes in the development and progression of breast cancer. We analyzed the differential expression, mutation status, methylation status, drug sensitivity, tumor mutation burden (TMB), microsatellite instability (MSI), immune checkpoints, tumor microenvironment (TME), and immune cell infiltration levels associated with VM-related genes in breast cancer. We created two VM subclusters out of breast cancer patients using consensus clustering, and discovered that patients in Cluster 1 had better survival outcomes compared to those in Cluster 2. The infiltration levels of T cells CD4 memory resting and T cells CD8 were higher in Cluster 1, indicating an immune-active state in this cluster. Additionally, we selected three prognostic genes (LAMC2, PIK3CA, and TFPI2) using Lasso, univariate, and multivariate Cox regression and constructed a risk model, which was validated in an external dataset. The prognosis of patients is strongly correlated with aberrant expression of VM-related genes, which advances our knowledge of the tumor immune milieu and enables us to identify previously unidentified breast cancer subtypes. This could direct more potent immunotherapy approaches.
