Prognostic nomogram based on pre-treatment HALP score for patients with advanced non-small cell lung cancer.

BACKGROUND: To explore the correlation of pre-treatment Hemoglobin-Albumin-Lymphocyte-Platelet (HALP) score with the prognosis of patients with advanced Non-Small Cell Lung Cancer (NSCLC) undergoing first-line conventional platinum-based chemotherapy. METHODS: In this retrospective cohort study, 203 patients with advanced NSCLC were recruited from January 2017 to December 2021. The cut-off value for the HALP score was determined by Receiver Operating Characteristic (ROC) curve analysis. The baseline characteristics and blood parameters were recorded, and the Log-rank test and Kaplan-Meier curves were applied for the survival analysis. In the univariate and multivariate analyses, the Cox regression analysis was carried out. The predictive accuracy and discriminative ability of the nomogram were determined by the Concordance index (C-index) and calibration curve and compared with a single HALP score by ROC curve analysis. RESULTS: The optimal cut-off value for the HALP score was 28.02. The lower HALP score was closely associated with poorer Progression-Free Survival (PFS) and Overall Survival (OS). The male gender and other pathological types were associated with shorter OS. Disease progression and low HALP were correlated with shorter OS and PFS. In addition, nomograms were established based on HALP scores, gender, pathology type and efficacy rating, and used to predict OS. The C-index for OS prediction was 0.7036 (95% CI 0.643 to 0.7643), which was significantly higher than the C-index of HALP at 6-, 12-, and 24-months. CONCLUSION: The HALP score is associated with the prognosis of advanced NSCLC patients receiving conventional platinum-based chemotherapy, and the nomogram established based on the HALP score has a better predictive capability for OS.

Development and Application of Machine Learning Models for Prediction of Soil Available Cadmium Based on Soil Properties and Climate Features.

Identifying the key influencing factors in soil available cadmium (Cd) is crucial for preventing the Cd accumulation in the food chain. However, current experimental methods and traditional prediction models for assessing available Cd are time-consuming and ineffective. In this study, machine learning (ML) models were developed to investigate the intricate interactions among soil properties, climate features, and available Cd, aiming to identify the key influencing factors. The optimal model was obtained through a combination of stratified sampling, Bayesian optimization, and 10-fold cross-validation. It was further explained through the utilization of permutation feature importance, 2D partial dependence plot, and 3D interaction plot. The findings revealed that pH, surface pressure, sensible heat net flux and organic matter content significantly influenced the Cd accumulation in the soil. By utilizing historical soil surveys and climate change data from China, this study predicted the spatial distribution trend of available Cd in the Chinese region, highlighting the primary areas with heightened Cd activity. These areas were primarily located in the eastern, southern, central, and northeastern China. This study introduces a novel methodology for comprehending the process of available Cd accumulation in soil. Furthermore, it provides recommendations and directions for the remediation and control of soil Cd pollution.

Reverse-sequence endoscopic nipple-sparing mastectomy with immediate implant-based breast reconstruction: an improvement of conventional minimal access breast surgery.

Background: Our center proposes a new technique that effectively provides space to broaden the surgical field of view and overcomes the limitations of endoscopy-assisted nipple-sparing mastectomy (E-NSM) by changing the dissection sequence and combining it with air inflation. The purpose of this study was to compare the clinical outcomes of the new technique designated "reverse-sequence endoscopic nipple-sparing mastectomy (R-E-NSM) with subpectoral breast reconstruction (SBR)" and the conventional E-NSM (C-E-NSM) with SBR. Method: All patients undergoing E-NSM with SBR at our breast center between April 2017 and December 2022 were included in this study. The cohort was divided into the C-E-NSM group and the R-E-NSM group. The operation time, anesthesia time, medical cost, complications, cosmetic outcomes, and oncological safety were compared. Results: Twenty-six and seventy-nine consecutive patients were included in the C-E-NSM and R-E-NSM groups, with average ages of 36.9 ± 7.0 years and 39.7 ± 8.4 years (P=0.128). Patients in the R-E-NSM group had significantly shorter operation time (204.6 ± 59.2 vs. 318.9 ± 75.5 minutes, p<0.001) and anesthesia time (279.4 ± 83.9 vs. 408.9 ± 87.4 minutes, p<0.001) and decreased medical costs [5063.4 (4439.6-6532.3) vs. 6404.2 (5152.5-7981.5), USD, p=0.001] and increase SCAR-Q scores (77.2 ± 17.1 vs. 68.8 ± 8.7, P=0.002) compared to the C-E-NSM group. Although trends increased in both the excellent rate of Ueda scores (53.8% vs. 42.3%, P = 0.144), excellent rate of Harris scores (44.0% vs. 63.1%, P=0.102), and decreased surgical complications (7.6% vs. 19.2%, P = 0.135) were observed in the R-E-NSM group, the differences were not significant. There were no significant differences in oncological outcomes between the two groups. Conclusion: R-E-NSM improves cosmetic outcomes and efficiency of C-E-NSM, reduces medical costs, and has a trend of lower surgical complications while maintaining the safety of oncology. It is a safe and feasible option for oncological procedures that deserves to be promoted and widely adopted in practice.

A novel technique of reverse-sequence endoscopic nipple-sparing mastectomy with direct-to-implant breast reconstruction: medium-term oncological safety outcomes and feasibility of 24-h discharge for breast cancer patients.

BACKGROUND: Due to the short operation time and no need for special instruments, reverse-sequence endoscopic nipple-sparing mastectomy (R-E-NSM) with direct-to-implant breast reconstruction (DIBR) has been rapidly becoming popular in the last three years. However, there has yet to be an evaluation of its oncologic safety or the feasibility of discharging patients within 24 h. MATERIALS AND METHODS: In this single-centre retrospective cohort study, individuals diagnosed with stage 0-III breast cancer between May 2020 and April 2022 who underwent traditional open mastectomy or R-E-NSM with DIBR were included. Follow-up started on the date of surgery and ended in December 2023. Data, including demographics, tumour characteristics, medium-term oncological outcomes, and postoperative complications, were collected and analyzed. Propensity score matching (PSM) was performed to minimize selection bias. RESULTS: This study included 1679 patients [median (IQR) age, 50 [44-57) years]. Of these, 344 patients underwent R-E-NSM with DIBR (RE-R group), and 1335 patients underwent traditional open mastectomy (TOM group). The median [IQR] follow-up time was 30 [24-36] months [29 (23-33) months in the RE-R group and 30([24-36) months in the TOM group]. Regarding before or after PSM, the P value of local recurrence-free survival (LRFS, 0.910 and 0.450), regional recurrence-free survival (RRFS, 0.780 and 0.620), distant metastasis-free survival (DMFS, 0.061 and 0.130), overall survival (OS, 0.260 and 0.620), disease-free survival (DFS, 0.120 and 0.330) were not significantly different between the RE-R group and the TOM group. The 3y-LRFS and 3y-DFS rates were 99.0% and 97.1% for the RE-R group and 99.5% and 95.3% for the TOM group, respectively. The rates of any complications and major complications were not significantly different between the RE-R patients who were discharged within 24 h and the RE-R patients who were not discharged within 24 h ( P =0.290, P =0.665, respectively) or the TOM patients who were discharged within 24 h ( P =0.133, P =0.136, respectively). CONCLUSIONS: R-E-NSM with DIBR is an innovative oncologic surgical procedure that not only improves cosmetic outcomes but also ensures reliable oncologic safety and fewer complications, enabling patients to be safely discharged within 24 h. A long-term prospective multicenter assessment will be supporting.

Clinical Outcomes of Transaxillary Reverse-Sequence Endoscopic Nipple-Sparing Mastectomy and Direct-to-Implant Prepectoral Breast Reconstruction: A Prospective Study of Initial 68 Procedures.

BACKGROUND: Minimal access breast surgery improves cosmetic outcomes over conventional breast surgery but still faces barriers in becoming standard procedure for breast reconstruction. This report introduces a novel technique of transaxillary reverse-sequence endoscopic nipple-sparing mastectomy (R-E-NSM) followed by direct-to-implant prepectoral breast reconstruction (DTI-PBR) and describes its clinical outcomes. METHODS: This prospective study enrolled patients who underwent R-E-NSM and DTI-PBR from March 2021 to December 2021 at a single institution. Perioperative data, surgical complications, oncologic outcomes, and patient- and surgeon-reported cosmetic results were noted. RESULTS: The 60 patients in this study who underwent 68 R-E-NSM and DTI-PBR had a mean age was 40.4 ± 10.3 years. The average durations of uni- and bilateral operations were 156.5 ± 48.3 min and 191.3 ± 36.1 min, respectively. The overall surgical complication rate was 13.3%, including 10.0% of patients with minor complications and 3.3% of patients with major complications. The study had one case (1.7%) of implant loss and one case (1.7%) of skin flap necrosis treated by reoperation. During the median follow-up period of 24 months, one patient (1.7%) who discontinued chemotherapy for myelosuppression experienced liver metastases 5 months postoperatively, and one patient experienced new-onset contralateral ductal carcinoma in situ 24 months postoperatively. The preoperative and 18-month postoperative Breast-Q scores for satisfaction with breasts, psychosocial well-being, sexual well-being, and chest well-being did not differ significantly, and the Scar-Q was 81.2 ± 14.5 points. The good-to-excellent rate in surgeon-reported cosmetic results reached 90%. CONCLUSIONS: Transaxillary R-E-NSM followed by DTI-PBR is a safe and efficient technique with high cosmetic outcomes and reliable medium-term oncologic results.

Effect of TEMPO-oxidized bacterial cellulose nanofibers stabilized Pickering emulsion of cinnamon essential oil on structure and properties of gelatin composite films.

Pure gelatin film often exhibits high hydrophilicity and a lack of antibacterial activity, hindering its practical application in the field of food preservation. To address these issues, we incorporated 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-oxidized bacterial cellulose (TOBC) nanofibers stabilized cinnamon essential oil (CEO) Pickering emulsions into the gelatin matrix to develop active food packaging films. The study revealed that the good distribution of emulsion droplets in the film matrix. While with increasing Pickering emulsion proportion, the microstructures of composite films were more heterogeneous, showing some pores or cavities. In addition, the insertion of TOBC-stabilized CEO emulsions could improve the elongation at break (EAB), water-resistance, UV blocking ability, and antibacterial activity of film, but reduced its tensile strength (TS) and water vapor barrier properties (WVP). Notably, the film prepared with 4 % TOBC-stabilized CEO Pickering emulsion demonstrated enhanced preservation of strawberries. Overall, the as-prepared gelatin-based active composite films have considerable potential for food packaging.

The immune inflammation factors associated with disease severity and poor prognosis in patients with COVID-19: A retrospective cohort study.

Coronavirus disease 2019 (COVID-19) is associated with immune dysregulation and cytokine storm. It is essential to explore the immune response characteristics of peripheral circulation in COVID-19 patients to reveal pathogenesis and predict disease progression. In this study, the levels of total immunoglobulins (IgG, IgM, IgA), complement (C3, C4)，lymphocyte subsets (CD3+ cell，CD4+ cell，CD8+ cell, NK cell, CD19+ cell and CD45+ cell) and cytokines (IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-17, IL-12p, IL-1ß, TNF-α, IFN-α and IFN-γ) were retrospectively analyzed in COVID-19 patients. A total of 513 patients were enrolled in this study, cases were distributed according to clinical status as mild or moderate (n = 212), severe survivors (n = 197) and severe non-survivors (n = 104). IL-6, IL-8, IL-10 and IFN-γ were increased in severe patients compared with non-severe patients, despite decreased CD45+ cell, CD3+ cell, CD4+ cell, CD8+ cell, CD19+ cell, and NK cell. Compared with severe survivors, the levels of L-6, IL-8 and IL-10 in non-survivors increased significantly, and levels of C3, CD45+ cell, CD3+ cell，CD4+ cell，CD8+ cell, and NK cell decreased. Moreover, age, IL-8, IL-10, CD8+cells and NK cell were independent risk factors for the severity of COVID-19. Multivariable regression showed increasing odds ratio of in-hospital death associated with tumor, older age, higher IL-8 level, and decreasing odds ratio of in-hospital death associated with increased levels of CD8+cell and NK cell. Finally, patients with tumor, or high IL-6 or high IL-10 expression and lower CD8+ or lower NK levels exhibited a significantly shorter survival time. In conclusion, our study provides findings of the immunological characteristics associated with disease severity to predict the progression of COVID-19. The immune inflammation factors, such as IL-6, IL-8, IL-10, CD8+ cell and NK cell, could serve as excellent biomarkers for monitoring or predicting COVID-19 progression therapeutic to COVID-19 patients.

NIR-triggered bacterial cellulose-based wound dressings for multiple synergistic therapy of infected wound.

Skin wounds are repaired by a complex series of events and overlapping phases in which bacterial infection and insufficient angiogenesis at the wound site delay the healing process. Thus, functional wound dressings with enhanced antibacterial activity and angiogenic capacity have attracted attention. Herein, bacterial cellulose (BC)-based dressings were successfully fabricated by functionalization with a polydopamine (PDA) coating and copper sulfide nanoparticles (CuS NPs). Under 808 nm laser illumination, the BC/PDA/CuS composite membranes exhibited outstanding adjustable photothermal and photodynamic activities as well as controlled Cu2+ release, endowing the composite membranes with synergetic antibacterial activity. Specially, a bactericidal efficiency of 99.7 % and 88.0 % for Staphylococcus aureus and Escherichia coli was achieved after treatment with BC/PDA/CuS5 sample under NIR irradiation (0.8 W/cm2, 10 min), respectively. Moreover, the BC/PDA/CuS5 composite membrane could enhance the angiogenesis due to the released Cu2+. In vivo experiments revealed that the BC/PDA/CuS5 composite membrane dressing could accelerate the wound closure process of the full-thickness skin defects with S. aureus by synergistically reducing inflammation, enhancing collagen deposition, and promoting vascularization under NIR irradiation. Additionally, the BC/PDA/CuS5 composite membrane exhibited high biocompatibility and biosafety. This work offers a new strategy to prepare multifunctional BC-based dressing for clinical wound healing.

An Innovative and Highly Efficient Single-Port Endoscopic Nipple-/Skin-Sparing Mastectomy and Dual-Plane Direct-to-Implant Breast Reconstruction: A Prospective Study from a Single Institution.

BACKGROUND: The difficulty in creating and maintaining a stable workspace of the breast makes endoscopic nipple-/skin-spring mastectomy (E-N/SSM) develop slowly. This study aims to report the preliminary results of a novel endoscopic technique for N/SSM followed by dual-plane direct-to-implant (DP-DTI) breast reconstruction. METHODS: A prospectively maintained database was reviewed that included patients who underwent single-axillary-incision E-N/SSM and DP-DTI breast reconstruction from September 2020 to April 2021 at a single institution by three surgeons. The data were collected prospectively and analyzed to determine the efficacy, feasibility, safety, and esthetic results of the operation, as well as quality of life (QoL). RESULTS: During the study period, a total of 68 E-N/SSM and DP-DTI reconstruction procedures through a single axillary incision were performed in 63 female patients. Among all the procedures, the majority were performed for grade 1-3 ptotic breasts (n =46, 73.0%). During the median follow-up of 26.5 months, the major and minor surgical complication rates were 1.6% (1/63) and 9.5% (6/63), respectively. The cosmetic complication rate was 14.3%. One patient suffered local recurrence 4 months postoperation. The average scores in patient-reported outcomes at 2 years postoperation of satisfaction with breast (66.57), psychosocial well-being (75.93) and sexual well-being (56.29) were not significantly different compared with the baseline, except for physical well-being: chest (69.85). CONCLUSIONS: The proposed procedure for E-N/SSM and DP-DTI breast reconstruction is feasible, time-saving and safe with good outcomes in terms of cosmetic results and QoL and expands the indications of DTI reconstruction to ptotic breasts, making it easier to popularize.

Minimally Invasive and Innovative Management of Prosthesis Infections in Endoscopic-Assisted Breast Reconstruction.

BACKGROUND: Implant infection continues to be the most common complication of breast reconstruction, and it can lead to serious consequences of implant loss. Recently, endoscopic-assisted nipple-sparing mastectomy with direct-to-implant breast reconstruction is being performed more frequently, with similar prosthetic infection incidence compared to conventional techniques. But there is little information published in the literature on the management of periprosthetic infection in endoscopic-assisted breast reconstruction. METHODS: A retrospective review was performed of patients who underwent endoscope-assisted breast reconstruction and developed periprosthetic infection between January 2020 and December 2022. Prosthesis infection was defined as any case where antibiotics were given, beyond the surgeon's standard perioperative period, in response to clinical signs such as swelling, pain, erythema, increased temperature, fever, etc. We summarized our clinical approach and treatment protocol for periprosthetic infection patients. Collected data include preoperative basic information, surgical details, postoperative data, and outcomes. RESULTS: A total of 580 patients (713 reconstructions) underwent endoscopic-assisted immediate breast reconstruction. There were 58 patients developed periprosthetic infection, 14 of whom had bilateral prosthesis reconstruction with unilateral prosthesis infection. The incidence of infection was 10.0%. Average follow-up was 17.3 ± 8.9 months (range = 2-37 months). Of the 58 patients, 53 (91.4%) patients successful salvaged implant and 5(8.6%) patients removed prosthesis. During follow-up, Baker III capsular contracture occurred in 2 patients (3.8%) who had radiotherapy. CONCLUSION: Our management of prosthesis infections in endoscopic-assisted breast reconstruction is easy, minimally invasive, and inexpensive. This method can be repeated if the implant infection does not improve after the first drainage. What's more, our data suggest that our prosthesis salvage of periprosthetic infection is effective.

Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of YK-029A in Treatment-Naive Patients With Advanced NSCLC Harboring EGFR Exon 20 Insertion Mutations: A Phase 1 Trial.

INTRODUCTION: Treatment options for treatment-naive patients with advanced NSCLC harboring EGFR exon 20 insertion (ex20ins) mutations are limited. This study evaluated the safety, tolerability, and pharmacokinetics of YK-029A, a third-generation EGFR tyrosine kinase inhibitor, and the preliminary efficacy of YK-029A in treatment-naive patients with EGFR ex20ins mutation. METHODS: This multicenter, dose-escalation, and dose-expansion phase 1 clinical trial enrolled patients with NSCLC harboring EGFR mutations. During the dose-escalation phase, YK-029A was orally administered using the traditional 3+3 principle at 50, 100, 150, 200, and 250 mg/d. In the dose-expansion phase, treatment-naive patients with EGFR ex20ins mutations were enrolled and administered YK-029A 200 mg/d. The primary end point was safety and tolerability. RESULTS: The safety analysis included 108 patients. No dose-limiting toxicity was observed, and the maximum tolerated dose was not reached. The most common treatment-emergent adverse events were anemia (50.9%), diarrhea (49.1%), and rash (34.3%). There was minimal drug accumulation after multiple doses. A total of 28 treatment-naive patients with EGFR ex20ins mutations were enrolled in the dose-expansion and 26 were included in the efficacy analysis. According to the independent review committee evaluation, the objective response rate was 73.1% (95% confidence interval: 52.21%-88.43%), and the disease control rate was 92.3% (95% confidence interval: 74.87%-99.05%). CONCLUSIONS: YK-029A was found to have manageable safety and be tolerable in patients with NSCLC harboring EGFR mutations and have promising antitumor activity in untreated patients with EGFR ex20ins mutations.

Correlation Between Postpartum Myometrial Elasticity and Obstetric Complications in Pregnant Women with Gestational Diabetes Mellitus.

Objective: To investigate postpartum myometrial elasticity in pregnant women with gestational diabetes mellitus (GDM) using shear wave elastography (SWE) and analyze the correlation between myometrial SWE values and obstetric complications. Methods: Clinical data of women who gave birth at Affiliated Hospital of Yangzhou University from August 2022 to July 2023 were retrospectively analyzed and divided into two groups based on GDM diagnosis: the GDM group and the healthy control group. SWE was used to measure the elasticity values of the anterior and posterior myometrial walls in both groups. Differences in placental attachment position and SWE values at the placental attachment site were compared between the two groups. Spearman correlation analysis was utilized to evaluate the correlation between SWE values and obstetric complications. Results: Glycated hemoglobin (HbA1c), homeostasis model assessment of insulin resistance (HOMA-IR), fasting plasma glucose (FPG), 2-hour postprandial glucose (2h PG), triglycerides (TG), and total cholesterol (TC) levels were higher in the GDM group than in the healthy control group (P<0.05). There was a statistically significant difference in placental attachment position between the two groups (P<0.05). In both the GDM (17.52±0.42 vs 25.29±0.74, P=0.001) and control groups (14.06±5.01 vs 22.20±6.34, P=0.001), mean SWE values were significantly lower for anterior versus posterior placental attachment, and mean SWE values were also significantly higher in the GDM versus control group for both anterior (17.52±0.42 vs 14.06±5.01, P=0.001) and posterior placental attachment (25.29±0.74 vs 22.20±6.34, P=0.001). Spearman correlation analysis showed that postpartum hemorrhage (r=0.632, P=0.017), preeclampsia (r=0.818, P=0.014), premature rupture of membranes (r=0.710, P=0.012), placental abruption (r=0.732, P=0.031), and ketoacidosis (r=0.729, P=0.022) were negatively correlated with average myometrial SWE values in the GDM group (P<0.05). Conclusion: SWE values at the placental attachment site were higher in GDM patients than in healthy pregnant women, and myometrial elasticity was positively correlated with obstetric complications.

The role of hydrogen therapy in Alzheimer's disease management: Insights into mechanisms, administration routes, and future challenges.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder predominantly affecting the elderly. While conventional pharmacological therapies remain the primary treatment for AD, their efficacy is limited effectiveness and often associated with significant side effects. This underscores the urgent need to explore alternative, non-pharmacological interventions. Oxidative stress has been identified as a central player in AD pathology, influencing various aspects including amyloid-beta metabolism, tau phosphorylation, autophagy, neuroinflammation, mitochondrial dysfunction, and synaptic dysfunction. Among the emerging non-drug approaches, hydrogen therapy has garnered attention for its potential in mitigating these pathological conditions. This review provides a comprehensively overview of the therapeutic potential of hydrogen in AD. We delve into its mechanisms of action, administration routes, and discuss the current challenges and future prospects, with the aim of providing valuable insights to facilitate the clinical application of hydrogen-based therapies in AD management.

Multifunctional Asymmetric Bacterial Cellulose Membrane with Enhanced Anti-Bacterial and Anti-Inflammatory Activities for Promoting Infected Wound Healing.

An asymmetric wound dressing acts as a skin-like structure serves as a protective barrier between a wound and its surroundings. It allows for the absorption of tissue fluids and the release of active substances at the wound site, thus speeding up the healing process. However, the production of such wound dressings requires the acquisition of specialized tools, expensive polymers, and solvents that contain harmful byproducts. In this study, an asymmetric bacterial cellulose (ABC) wound dressing using starch as a porogen has been developed. By incorporating silver-metal organic frameworks (Ag-MOF) and curcumin into the ABC membrane, the wound dressing gains antioxidant, reactive oxygen species (ROS) scavenging, and anti-bacterial activities. Compared to BC-based wound dressings, this dressing promotes efficient dissolution and controlled release of curcumin and silver ions. In a full-thickness skin defect model, wound dressing not only inhibits the growth of bacteria on infected wounds but also regulates the release of curcumin to reduce inflammation and promote the production of epithelium, blood vessels, and collagen. Consequently, this dressing provides superior wound treatment compared to BC-based dressing.

Breast cancer prediction model based on clinical and biochemical characteristics: clinical data from patients with benign and malignant breast tumors from a single center in South China.

OBJECTIVE: Breast cancer is the most prevalent cancer and is second leading cause of death from malignancy among women worldwide. In addition to tumor factors, the host characteristics of tumors have been paid more and more attention by the medical community. This study aimed to develop a breast cancer prediction model for the Chinese population using clinical and biochemical characteristics. METHODS: This is a retrospective study. From 2012 to 2021, we selected 19,751 patients with breast diseases from the Guangdong Hospital of Traditional Chinese Medicine, which included 5660 patients with breast cancer and 14,091 patients with benign breast diseases-75% of patients were randomly assigned to the training group and 25% to the test group using a total of 34 clinical and biochemical characteristics. Significant clinical signs were investigated, and logistic regression with recursive feature elimination (RFE) model was used to develop a prediction model for distinguishing benign from malignant breast diseases. The prediction model's accuracy, precision, sensitivity, specificity, and area under the ROC curve (AUC) were calculated. RESULTS: Clinical statistics demonstrated that the prediction model comprised 19 clinical characteristics had statistical separability in both the training group and the test group, as well as good sensitivity and prediction. CONCLUSIONS: This model based on biochemical parameters demonstrates a significant predictive effect for breast cancer and may be useful as a reference for invasive tissue biopsy in patients undergoing BI-RADS 3 and 4A breast imaging.

Single axillary incision reverse-order endoscopic nipple/skin-sparing mastectomy followed by subpectoral implant-based breast reconstruction: Technique, clinical outcomes, and aesthetic results from 88 preliminary procedures.

BACKGROUND: Single axillary incision reverse-order endoscopic nipple-sparing mastectomy overcomes the limitations of conventional endoscopic nipple-sparing mastectomy application. We introduce this technique and report the preliminary results of this study. METHODS: Patients who received single axillary incision reverse-order endoscopic nipple-/skin-sparing mastectomy from May 2020 to May 2022 were enrolled from a single institution. Data were analyzed to evaluate the safety and effectiveness of this technique. Patient-reported and surgeon-reported cosmetic outcomes were collected. RESULTS: In total, 68 patients who underwent 88 single axillary incision reverse-order endoscopic nipple-/skin-sparing mastectomy combined with subpectoral implant-based breast reconstruction were enrolled in the current study. The overall complication rate was 10.3%. In total, 2.9% of patients suffered from major complications, and 5 (7.4%) experienced minor complications. Only 1 patient experienced partial nipple-areola complex necrosis. During a median follow-up time of 24 months, the locoregional recurrence and distant metastasis rate was both 1.6%. In the surgeon-reported cosmetic results, 92.1% of patients achieved good or excellent results. The mean SCAR-Q scores were 82.07 ± 8.86, and 85.3% evaluated their breasts as good or excellent. The mean overall cost was 5,670.4 ± 1,351.3 USD. The total mean operation time and maturity-stage mean operation time were 234.3 ± 80.4 and 172.55 ± 41.29 min, respectively. According to cumulative sum plot analysis, approximately 18 cases were needed for surgeons to decrease their operation time significantly and complication rate. CONCLUSION: Single axillary incision reverse-order endoscopic nipple-sparing mastectomy is a safe, less expensive, and efficient surgical technique with reliable intermediate-term oncologic safety. For suitable candidates, the technique with subpectoral implant-based breast reconstruction can provide a good cosmetic outcome.

Selective BD2 Inhibitor Exerts Anti-Fibrotic Effects via BRD4/FoxM1/Plk1 Axis in Orbital Fibroblasts From Patients With Thyroid Eye Disease.

Purpose: We investigated the therapeutic potential of ABBV744, a bromodomain and extra-terminal (BET) inhibitor with selectivity for the second bromodomain (BD2) in thyroid eye disease (TED). The anti-fibrotic effects of ABBV744 and its underlying mechanism were explored in cultured orbital fibroblasts (OFs) from patients with TED. Methods: Immunohistochemistry (IHC) and real-time quantitative polymerase chain reaction (RT-qPCR) assays were conducted on orbital connective tissues from TED and controls. RT-qPCR, Western blot, Cell-counting Kit-8 (CCK-8), and 5-ethynyl-2'-deoxyuridine (EdU) cell proliferation assays were conducted on OFs isolated from patients with TED. Results: The expression of BRD4 was upregulated in the orbital tissues of patients with TED relative to controls and in TED OFs stimulated with TGF-ß1. Further, we showed that BRD4 modulated the profibrotic process through the interaction with Forkhead Box M1 (FoxM1) and its downstream molecule Polo-like kinase 1 (Plk1) in cultured TED OFs. Inhibition of BRD4 both by BD2 selective inhibitor ABBV744 and pan-BET inhibitor JQ1 exerted anti-fibrotic effects, whereas ABBV744 displayed superior anti-fibrotic effects and acceptable safety compared to JQ1. Conclusions: We conclude that BDR4 may modulate the profibrotic process in OFs of patients with TED via the FoxM1/Plk1 axis, and that selectively targeting BD2 domain of BRD4 may therefore be a potential therapeutic option for treating patients with TED.

Effects of vegetation succession on soil microbial stoichiometry in Phyllstachys edulis stands following abandonment.

Moso bamboo (Phyllostachys edulis) is China's most important economic bamboo species. With a continuous decline in the value of its shoots and timber and an increase in affiliated labor and production costs, many of these stands have been abandoned, resulting in the occurrence of vegetation succession. Currently, our understanding on changes in soil microbial stoichiometric and entropic effects and associated imbalances following stand abandonment is limited. Accordingly, this study explores three timescales of Ph. edulis stand abandonment (i.e., 0, 9, and 21 years) to investigate soil-microbial carbon (C), nitrogen (N), and phosphorus (P) dynamics within a 30 cm soil profile. Results showed that (1) following abandonment, vegetation succession significantly influenced soil carbon (Csoil), nitrogen (Nsoil), and phosphorus (Psoil), microbial biomass (Cmic), nitrogen (Nmic), and phosphorus (Pmic), and Csoil:Nsoil:Psoil and Cmic:Nmic:Pmic ratios. Additionally, Csoil, Nsoil, Psoil, Cmic, Nmic, Pmic all increased significantly over time following abandonment. Moreover, Csoil:Nsoil, Cmic:Pmic, and Nmic:Pmic ratios clearly increased while Csoil:Psoil, Nsoil:Psoil, and Cmic:Nmic ratios all significantly decreased. (2) Soil microbial entropy nitrogen (qMBN) and soil microbial imbalances in Cimb:Nimb increased while soil microbial entropy carbon (qMBC), soil microbial entropy phosphorus (qMBP), and soil microbial imbalances in Cimb:Pimb and Nimb:Pimb decreased over time following abandonment. (3) Redundancy analysis (RDA) indicated that Csoil:Nsoil and Cmic:Pmic ratios were key influencing factors of microbial quotient (qMB), explaining 55.35 % and 24.39 % of variation, respectively. Following abandonment, positive or negative successional impacts on Csoil:Nsoil:Psoil, microbial C, N, P stoichiometric imbalances (Cimb:Nimb:Pimb), and Csoil:Nsoil:Psoil ratios had a positive effect on qMB. Collectively, these findings highlight the importance of Csoil:Nsoil:Psoil and Cimb:Nimb:Pimb ratios in regulating qMB induced by vegetation succession following Ph. edulis abandonment, and provide valuable information for vegetation restoration and establishment of bamboo mixed forest.
