Tabular review of contemporary fenestrated-branched endovascular aortic repair experiences for treatment of thoracoabdominal aortic aneurysms.

INTRODUCTION: Repair of thoracoabdominal aortic aneurysms (TAAAs) represents a technical challenge regardless of which technique is used. Open surgical repair (OSR) is the time-tested option against which novel techniques must be compared and it is still considered the gold standard option for younger, fit patients with heritable aortic diseases. Endovascular repair offers a less-invasive alternative in patients with suitable anatomy. This article aims to present a tabular review of the contemporary published data on endovascular repair of TAAAs using fenestrated-branched techniques. EVIDENCE ACQUISITION: The published literature for single-center and multicenter studies evaluating the outcomes of FB-EVAR for TAAAs was searched using MEDLINE and Embase databases. Studies published between January 1st 2010 and July 11th 2024, in the English language which provided data on FB-EVAR of TAAAs with more than fifty reported cases were included. EVIDENCE SYNTHESIS: The average patient age at time of repair was 71 years old with majority of males (65.5%). Most patients presented with a Crawford Extent II TAAAs (21.6%), followed by Extent III (21.2%). Early mortality was 4.9% for the entire cohort. The most prevalent adverse event was acute kidney injury (9.4%), followed by spinal cord injury (8.0%). CONCLUSIONS: FB-EVAR of TAAAs continues to evolve. Pooled analysis of early mortality and morbidity is lower in this tabular review than historical outcomes of open TAAA repair.

Early salvage therapy with anti-PD-1 antibody Camrelizumab in patients with advanced cervical cancer: a retrospective study.

OBJECTIVE: To observe the clinical efficacy of Camrelizumab in patients with advanced cervical cancer who presented with resistance to initial therapy. METHODS: We retrieved data from 25 patients with advanced (stage IIA2-IV) cervical cancer who were administered a combination salvage therapy with Camrelizumab due to the poor response to initial chemotherapy. The primary outcome was objective response rate (ORR) and disease control rate (DCR), the secondary endpoints included progression-free survival (PFS) and the occurrence of adverse events. To evaluate its long-term effect on PFS, we included 64 patients diagnosed with stage IIA2-IV during the study period, who were responsive to initial radiotherapy or chemotherapy and received conventional therapy as control. RESULTS: Camrelizumab exhibits a high salvage treatment efficacy, with ORR of 80.0% (20/25) and DCR of 88.0% (22/25) in Camrelizumab salvage group (CS group). The PFS in CS group was significantly longer than that in control group. The median follow-up time were 18.1 and 18.3 months in the CS group and the control group, respectively, and neither achieved median PFS. The adverse event (AEs) rates in the CS and control groups were 52.0% (13/25) and 51.6% (33/64), in which the most common adverse events were myelosuppression, cutaneous capillary endothelial proliferation (CCEP), and elevated liver enzymes, and the grade of AEs was less than grade 3 in all patients. CONCLUSION: Camrelizumab demonstrated promising efficacy and safety as the early salvage treatment for patients with advanced cervical cancer.

Potential of semen coicis in enhancing the anti-tumor effects of PD-1 inhibitor on A549 cell lines by blocking the PI3K-AKT-mTOR pathway.

BACKGROUND: The objective of this research was to investigate how the combination of semen coicis extract and PD-1 inhibitors can potentially work together to enhance the anti-tumor effects, with a focus on understanding the underlying mechanism. METHODS: We obtained the active components and specific targets of semen coicis in the treatment of NSCLC from various databases, namely TCMSP, GeneCard, and OMIM. By utilizing the STRING database and Cytoscape software, we established a protein interaction network (PPI) for the active ingredient of semen coicis and the target genes related to NSCLC. To explore the potential pathways involved, we conducted gene ontology (GO) and biological pathway (KEGG) enrichment analyses, which were further supported by molecular docking technology. Additionally, we conducted cyto-inhibition experiments to verify the inhibitory effects of semen coicis alone or in combination with a PD-1 inhibitor on A549 cells, along with examining the associated pathways. Furthermore, we investigated the synergistic mechanism of these two drugs through cytokine release experiments and the PD-L1 expression study on A549 cells. RESULTS: Semen coicis contains two main active components, Omaine and (S)-4-Nonanolide. Its primary targets include PIK3R1, PIK3CD, PIK3CA, AKT2, and mTOR. Molecular docking experiments confirmed that these ingredients and targets form stable bonds. In vitro experiments showed that semen coicis demonstrates inhibitory effects against A549 cells, and this effect was further enhanced when combined with PD-1 inhibitors. PCR and WB analysis confirmed that the inhibition of the PI3K-AKT-mTOR pathway may contribute to this effect. Additionally, semen coicis was observed to decrease the levels of IFN-γ, IL-6, and TNF-α, promoting the recovery of the human anti-tumor immune response. And semen coicis could inhibit the induced expression of PD­L1 of A549 cells stimulated by IFN­Î³ as well. CONCLUSION: Semen coicis not only has the ability to kill tumor cells directly but also alleviates the immunosuppression found in the tumor microenvironment. Additionally, it collaboratively enhances the effectiveness of PD-1 inhibitors against tumors by blocking the activation of PI3K-AKT-mTOR.

Predictive progression outcomes and risk stratification in patients with recurrent or metastatic nasopharyngeal carcinoma who received first-line immunochemotherapy.

PURPOSE: Progression after first-line immunochemotherapy (ICT) for recurrent or metastatic nasopharyngeal carcinoma (R/M NPC) is a clinical concern due to subsequent limited treatment options. This study firstly predicted the progress outcome. METHODS: A cohort of 186 R/M NPC cases that received first-line ICT was included for developing a Cox regression model for progression-free survival (PFS) and risk stratification, which was verified by cross-validation. Discrimination and calibration were evaluated. Progression sites in risk groups was shown with a Sankey diagram. RESULTS: Baseline predictors including liver metastasis, trend of plasma Epstein-Barr virus DNA copies, lymphocyte-to-monocyte ratio, and level of platelet and lactate dehydrogenase were identified for model construction, which stratify the cohort into low, middle, and high-risk groups. The overall concordance index (C-index) was 0.67 (95% CI 0.62-0.73). The area under the curve (AUC) was 0.68 (95% CI 0.60-0.76), 0.74 (95% CI 0.66-0.82), 0.75 (95% CI 0.65-0.84) at predicting 12, 18, and 24 months PFS, indicating a moderate accuracy. Cross-validation showed the model performance was robust. Compared with the low-risk group (median PFS: 24.4 months, 95% CI 18.4 months to not reached), the high-risk group (median PFS: 7.1 months, 95% CI 6.4-10.1 months; hazard risk: 7.4, 95% CI 4.4-12.4, p < 0.001) progressed with more liver metastasis after ICT resistance. CONCLUSION: It was the first study that described the risk factors and progression characteristics in R/M NPC patients who received first-line ICT, investigating the progression patterns, which was helpful to identify patients with different risks and help guide personalized interventions.

Correlation analysis of cardiopulmonary exercise test indices and conditions of overweight patients with obstructive sleep apnea: a retrospective study

ABSTRACT BACKGROUND: The cardiopulmonary function of patients with obstructive sleep apnea (OSA) is significantly lower than that of patients with simple snoring and is significantly related to the severity of OSA. Currently, only a few studies have been conducted on cardiopulmonary exercise testing in overweight patients with OSA. OBJECTIVE: To analyze the correlation between cardiopulmonary exercise test (CPET) indices and the condition of overweight patients with OSA. DESIGN AND SETTING: Retrospective study in Guangdong Provincial Hospital of Chinese Medicine. METHODS: This study included 73 hospitalized overweight patients. The patients were divided into no, mild, moderate, and severe OSA groups. Differences in the CPET indices among the four groups were compared. The correlation between the CPET indices and conditions was analyzed. RESULTS: No, mild, moderate, and severe OSA groups had 18 men and 5 women, 11 men and 3 women, 12 men and 2 women, and 21 men and 1 woman, respectively (P > 0.05). No significant difference was observed in resting pulmonary function among the four groups (P > 0.05). In the CPET, the anaerobic threshold, maximum oxygen uptake, and oxygen pulse were significantly lower in the severe OSA group than those in the normal OSA group (P < 0.05). Moreover, CPET indices negatively correlated with the apnea-hypopnea index. CONCLUSION: Changes in CPET indices occurred earlier than changes in resting pulmonary function in patients with OSA. CPET might be a potential method for evaluating the severity of OSA combined with overweight status.

Long noncoding RNA-mediated epigenetic regulation of auxin-related genes controls shade avoidance syndrome in Arabidopsis.

The long noncoding RNA (lncRNA) AUXIN-REGULATED PROMOTER LOOP (APOLO) recognizes a subset of target loci across the Arabidopsis thaliana genome by forming RNA-DNA hybrids (R-loops) and modulating local three-dimensional chromatin conformation. Here, we show that APOLO regulates shade avoidance syndrome by dynamically modulating expression of key factors. In response to far-red (FR) light, expression of APOLO anti-correlates with that of its target BRANCHED1 (BRC1), a master regulator of shoot branching in Arabidopsis thaliana. APOLO deregulation results in BRC1 transcriptional repression and an increase in the number of branches. Accumulation of APOLO transcription fine-tunes the formation of a repressive chromatin loop encompassing the BRC1 promoter, which normally occurs only in leaves and in a late response to far-red light treatment in axillary buds. In addition, our data reveal that APOLO participates in leaf hyponasty, in agreement with its previously reported role in the control of auxin homeostasis through direct modulation of auxin synthesis gene YUCCA2, and auxin efflux genes PID and WAG2. We show that direct application of APOLO RNA to leaves results in a rapid increase in auxin signaling that is associated with changes in the plant response to far-red light. Collectively, our data support the view that lncRNAs coordinate shade avoidance syndrome in A. thaliana, and reveal their potential as exogenous bioactive molecules. Deploying exogenous RNAs that modulate plant-environment interactions may therefore become a new tool for sustainable agriculture.

MicroRNA-181a regulates Treg functions via TGF-ß1/Smad axis in the spleen of mice with acute gouty arthritis induced by MSU crystals.

Regulatory T cells (Tregs) play critical roles in restricting inflammatory pathogenesis and limiting undesirable Th2 response to environmental allergens. However, the role of miR-181a in regulating acute gouty arthritis (AGA) and Treg function remains unclear. This study aimed to investigate the potential roles of miR-181a in Treg immunity and the associated signaling pathway in the AGA mouse model. A solution with monosodium urate (MSU) crystals was injected into the joint tissue of mice to induce AGA. ELISA was used to examine inflammatory factors in blood samples, and flow cytometry was used to analyze Treg profile in mice with MSU-induced AGA. Cell proliferation and viability were assessed by CCK-8 assay. TGF-ß1/Smad signaling activation was detected by western blot. We found that miR-181a expression showed a positive correlation with the changes of splenic Tregs percentage in AGA mice. miR-181a regulated the TGF-ß1/Smad axis, since the transfection of miR-181a mimic increased the level of TGF-ß1 and the phosphorylation of Smad2/3 in Tregs in AGA mice. Additionally, miR-181a mimic also promoted responses of Tregs via TGF-ß1 in vitro and in vivo. Our work uncovered a vital role of miR-181a in the immune function of Treg cells by mediating the activity of the TGF-ß1/Smad pathway in the AGA mouse model induced by MSU.

Phenotype and Genotype of a Cohort of Chinese Children with Early-Onset Protein-Losing Enteropathy.

OBJECTIVES: To examine the phenotypes and perform next-generation sequencing in children with early-onset protein-losing enteropathy. STUDY DESIGN: We performed a retrospective review of 27 children with early-onset protein-losing enteropathy. Patients were characterized on clinical, immunologic, and systemic involvements. Targeted gene panel sequencing and whole-exome sequencing were performed in 9 patients. RESULTS: In 27 patients (55.6% male), median age of disease onset was 173 days, and 59.3% had onset of disease before 1 year of age. Initial gastrointestinal symptoms included diarrhea (74.1%), vomiting (33.3%), and abdominal distention (48.1%). All patients had hypoalbuminemia, with an average serum albumin concentration of 20.2 ± 5.4 g/L. Hypogammaglobulinemia was identified in 72% of the patients. Upper endoscopy showed typical presentation of intestinal lymphangiectasia (n = 13). Patients frequently received intravenous albumin and immunoglobulin infusions as well as parenteral nutrition. Next-generation sequencing in 9 patients with available DNA showed 1 patient had compound heterozygous CCBE1 mutations and 2 had novel homozygous DGAT1 mutations. Monogenic diseases were identified in 3 of 9 patients who underwent genetic sequencing. Three subjects (11.1%) died, of whom 2 had homozygous DGAT1 mutations. No significant correlation was found between age of symptom onset, serum albumin, serum IgG, lymphocyte count, CD4+ cells, and mortality. CONCLUSIONS: Monogenic diseases may be observed in children with early-onset protein-losing enteropathy, and genetic evaluation with next-generation sequencing should be considered.

Familial Risk of Appendicitis: A Nationwide Population Study.

OBJECTIVE: To investigate the familial risk of appendicitis in the general population. STUDY DESIGN: A nationwide, cross-sectional study consisting of 24 349 599 Taiwan National Health Insurance beneficiaries in 2015 was conducted. Among them, 788 042 individuals had at least 1 first-degree relative with appendicitis. The familial relative risks (RRs) of appendicitis and familial transmission were estimated. RESULTS: The overall RR (95% CI) of appendicitis in individuals with any affected first-degree relatives was 1.67 (1.64-1.71) compared with the general population. The RRs for individuals with an affected twin, sibling, offspring, and parent were 3.40 (2.66-4.35), 1.98 (1.92-2.04), 1.55 (1.51-1.59), and 1.54 (1.50-1.58), respectively. The RRs for individuals with 1, 2, 3 or more affected first-degree relatives were 1.65 (1.62-1.68), 2.63 (2.37-2.91), and 6.70 (4.22-10.63), respectively. Furthermore, there was an age-dependent trend of the RRs, with the greatest RR in the youngest group. The estimated familial transmission (genetic plus shared environmental contribution to the total phenotypic variance of appendicitis) was 23.2%. CONCLUSION: Individuals with a family history of appendicitis have an increased risk of appendicitis. This risk is age-dependent and related to the genetic distance and numbers of affected relatives.

Biocontrol potential of saline- or alkaline-tolerant Trichoderma asperellum mutants against three pathogenic fungi under saline or alkaline stress conditions.

Salinity and alkalinity are major abiotic stresses that limit growth and development of poplar. We investigated biocontrol potential of saline- and alkaline-tolerant mutants of Trichoderma asperellum to mediate the effects of salinity or alkalinity stresses on Populus davidiana×P. alba var. pyramidalis (PdPap poplar) seedlings. A T-DNA insertion mutant library of T. asperellum was constructed using an Agrobacterium tumefaciens mediated transformation system; this process yielded sixty five positive transformants (T1-T65). The salinity tolerant mutant, T59, grew in Potato Dextrose Agar (PDA) containing up to 10% (1709.40mM) NaCl. Under NaCl-rich conditions, T59 was most effective in inhibiting Alternaria alternata (52.00%). The alkalinity tolerant mutants, T3 and T5, grew in PDA containing up to 0.4% (47.62mM) NaHCO3. The ability of the T3 and T5 mutants to inhibit Fusarium oxysporum declined as NaHCO3 concentrations increased. NaHCO3 tolerance of the PdPap seedlings improved following treatment with the spores of the WT, T3, and T5 strains. The salinity tolerant mutant (T59) and two alkalinity tolerant mutants (T3 and T5) generated in this study can be applied to decrease the incidence of pathogenic fungi infection under saline or alkaline stress.

Phylogeny and bioactivity of epiphytic Gram-positive bacteria isolated from three co-occurring antarctic macroalgae.

Marine macroalgae are emerging as an untapped source of novel microbial diversity and, therefore, of new bioactive secondary metabolites. This study was aimed at assessing the diversity and antimicrobial activity of the culturable Gram-positive bacteria associated with the surface of three co-occurring Antarctic macroalgae. Specimens of Adenocystis utricularis (brown alga), Iridaea cordata (red alga) and Monostroma hariotii (green alga) were collected from the intertidal zone of King George Island, Antarctica. Gram-positive bacteria were investigated by cultivation-based methods and 16S rRNA gene sequencing, and screened for antimicrobial activity against a panel of pathogenic microorganisms. Isolates were found to belong to 12 families, with a dominance of Microbacteriaceae and Micrococcaceae. Seventeen genera of Actinobacteria and 2 of Firmicutes were cultured from the three macroalgae, containing 29 phylotypes. Three phylotypes within Actinobacteria were regarded as potentially novel species. Sixteen isolates belonging to the genera Agrococcus, Arthrobacter, Micrococcus, Pseudarthrobacter, Pseudonocardia, Sanguibacter, Staphylococcus, Streptomyces and Tessaracoccus exhibited antibiotic activity against at least one of the indicator strains. The bacterial phylotype composition was distinct among the three macroalgae species, suggesting that these macroalgae host species-specific Gram-positive associates. The results highlight the importance of Antarctic macroalgae as a rich source of Gram-positive bacterial diversity and potentially novel species, and a reservoir of bacteria producing biologically active compounds with pharmacological potential.

Frequency and clinical correlates of elevated plasma Epstein-Barr virus DNA at diagnosis in peripheral T-cell lymphomas.

Epstein-Barr virus (EBV)-encoded RNAs (EBER) in tumor tissue and cell-free plasma EBV-DNA (pEBVd) are detected in EBV-associated lymphomas. Studies have suggested that EBER+ peripheral T-cell lymphomas (PTCL) have worse prognosis but the role of EBV in these neoplasms remains unclear. pEBVd is quantitative and more easily amenable to standardization than EBER, but frequency of pEBVd detection, clinical impact and agreement with EBER status in PTCL are unknown. We retrospectively assessed frequency of detectable pre-treatment pEBVd, presence of EBER in tumor tissue, and outcomes in 61 of 135 EBV-assessable PTCL patients. Fifteen of 61 patients (24.5%, 95% CI: 14-37%) were pre-treatment pEBVd+, with no significant differences in baseline characteristics or treatment between pEBVd+ and pEBVd- patients. EBER-ISH was performed on 10 pEBVd+ and 35 pEBVd- tumors. All 10 pEBVd+ patients were EBER+, but 9 pEBVd- patients were also EBER+. With median follow up of 24 months (range 1-96), overall survival (OS) was shorter in pEBVd+ compared to pEBVd- patients (13 vs. 72 months; p = 0.04). In our retrospective study, pre-treatment pEBVd was elevated in 25% of PTCL patients, was highly specific for EBER+ tumors, and was associated with shorter survival. pEBVd should be further explored as a prognostic variable and tumor biomarker in PTCL.

Single-center study on transplantation of livers donated after cardiac death: A report of 6 cases.

Effective use of all available donated organs is critical, in order to meet the increasing demand for transplants. The present study explored liver transplantation with livers that were donated following cardiac death (DCD). According to the guidelines established by The Red Cross Society of China, 42 DCD organs were procured. Selected donors were treated with extracorporeal membrane oxygenation (ECMO) prior to the organ retrieval. The present single-center study included 6 liver transplantations of DCD organs (5 liver transplants and 1 liver-kidney combined transplant). All 6 recipients had a successful recovery without significant complications. The serum alanine transaminase, total bilirubin and international normalized ratio returned to the normal levels within a short period of time following transplantation, and the liver function remained normal during the follow-up period, which lasted up to 24 months. The present report demonstrated the feasibility of orthotopic liver transplantation using DCD livers. The pre-conditioning DCD donors and optimization of the recipient's condition using ECMO, played a crucial role in ensuring the success of transplantation.
