RESUMO

Background: Several studies indicated that inflammatory bowel disease (IBD) may contribute to increased susceptibility to primary biliary cholangitis (PBC). However, the causal relationship between IBD and PBC remains unclear. Methods: The genetic variant data of patients with IBD and PBC were obtained from published genome-wide association studies (GWASs). The IBD data were further divided into a discovery dataset and a validation dataset depending on the data source. We conducted a two-sample Mendelian randomization (MR) analysis using the inverse variance weighting (IVW), MR-Egger, weighted median (WM), MR robust adjusted profile score (MR-RAPS), and maximum likelihood (ML) methods, with IVW being the main focus, to verify the causal relationship between IBD and PBC. Additionally, a series of sensitivity analyses were performed to ensure the reliability of the results. Results: In the discovery cohort, the IVW analysis results (OR = 1.114, P = 0.011) indicated a significant association between IBD and PBC. The MR-RAPS (OR = 1.130, P = 0.007) and ML (OR = 1.115, P = 0.011) analyses yielded results consistent with those of IVW in confirming IBD as a risk factor for PBC. In the validation cohort, consistent findings were observed regarding the causal relationship between IBD and PBC using IVW, MR-RAPS, and ML analyses; all three methods identified IBD as a risk factor for developing PBC. By the IVW analysis, Crohn's disease (CD) emerged as the most prominent subtype of IBD associated with an increased risk of developing PBC in both the discovery cohort (OR = 1.068, P = 0.049) and the validation cohort (OR = 1.082, P = 0.019). Conclusion: The results of the MR analysis suggest a causal relationship between IBD and PBC, highlighting the necessity for proactive PBC prevention in patients with IBD, particularly those with CD.

RESUMO

Tumor invasion and metastasis are the processes that primarily cause adverse outcomes in patients with cervical cancer. Cancer-associated fibroblasts (CAFs), which participate in cancer progression and metastasis, are novel targets for the treatment of tumors. The present study aimed to assess the heterogeneity of CAFs in the cervical cancer microenvironment through single-cell RNA sequencing. After collecting five cervical cancer samples and obtaining the CAF-associated gene sets, the CAFs in the cervical cancer microenvironment were divided into myofibroblastic CAFs and extracellular (ec)CAFs. The ecCAFs appeared with more robust pro-tumorigenic effects than myCAFs according to enrichment analysis. Subsequently, through combining the ecCAF hub genes and bulk gene expression data for cervical cancer obtained from The Cancer Genome Atlas and Gene Ontology databases, univariate Cox regression and least absolute shrinkage and selection operator analyses were performed to establish a CAF-associated risk signature for patients with cancer. The established risk signature demonstrated a stable and strong prognostic capability in both the training and validation cohorts. Subsequently, the association between the risk signature and clinical data was evaluated, and a nomogram to facilitate clinical application was established. The risk score was demonstrated to be associated with both the tumor immune microenvironment and the therapeutic responses. Moreover, the signature also has predictive value for the prognosis of head and neck squamous cell carcinoma, and bladder urothelial carcinoma, which were also associated with human papillomavirus infection. In conclusion, the present study assessed the heterogeneity of CAFs in the cervical cancer microenvironment, and a subgroup of CAFs that may be closely associated with tumor progression was defined. Moreover, a signature based on the hub genes of ecCAFs was shown to have biomarker functionality in terms of predicting survival rates, and therefore this CAF subgroup may become a therapeutic target for cervical cancer in the future.

RESUMO

Purpose: Immunological regimens are an important area of research for treating multiple myeloma (MM). Plasma cells play a crucial role in immunotherapy. Patients and Methods: In our study, we used both single-cell RNA sequencing (scRNA-seq) and bulk sequencing techniques to analyze MM patients. We analyzed each sample using gene set variation analysis (GSVA) based on immune-related gene sets. We also conducted further analyses to compare immune infiltration, clinical characteristics, and expression of immune checkpoint molecules between the H-S100A9 and L-S100A9 groups of MM patients. Results: We identified eight subpopulations of plasma cells, with S100A9 plasma cells being more abundant in patients with 1q21 gain and 1q21 diploid. CellChat analysis revealed that GAS and HGF signaling pathways were prominent in intercellular communication of S100A9 plasma cells. We identified 14 immune-related genes in the S100A9 plasma cell population, which allowed us to classify patients into the H-S100A9 group or the L-S100A9 group. The H-S100A9 group showed higher ESTIMATE, immune and stroma scores, lower tumor purity, and greater immune checkpoint expression. Patients with 1q21 gain and four or more copies had the lowest ESTIMATE score, immune score, stroma score, and highest tumor purity. Drug sensitivity analysis indicated that the H-S100A9 group had lower IC50 values and greater drug sensitivity compared to the L-S100A9 group. Quantitative reverse transcription (RT-q) PCR showed significantly elevated expression of RNASE6, LYZ, S100A8, S100A9, and S100A12 in MM patients compared to the healthy control group. Conclusion: Our study has identified a correlation between molecular subtypes of S100A9 plasma cells and the response to immunotherapy in MM patients. These findings improve our understanding of tumor immunology and provide guidance for developing effective immunotherapy strategies for this patient population.

RESUMO

OBJECTIVE: The investigation of the role of preoperative conization in cervical cancer aiming to explore its potential clinical significance. DATA SOURCES: Cochrane Library, Embase, PubMed, and Web of Science, up to April 28, 2023. METHODS OF STUDY SELECTION: (1) Observational cohort studies, (2) studies comparing radical hysterectomy with preoperative conization (CO) vs radical hysterectomy without preoperative conization (NCO) in patients with early-stage cervical cancer, and (3) studies comparing disease-free survival outcomes. TABULATION, INTEGRATION, AND RESULTS: Two reviewers independently extracted the data and assessed the quality of the studies. The meta-analysis used combined hazard ratios along with their corresponding 95% confidence intervals to compare CO and NCO. We conducted a Bayesian network meta-analysis using Markov chain Monte Carlo methods to compare minimally invasive CO, open CO, minimally invasive NCO, and open NCO. Our study included 15 retrospective trials, 10 of which were used to traditional pairwise meta-analysis and 8 for network meta-analysis. The NCO group exhibited a notably higher probability of cancer recurrence than the CO group (hazard ratio, 0.52; 95% confidence interval, 0.41-0.65). In the network meta-analysis, minimally invasive NCO showed the worst survival outcome. CONCLUSION: Preoperative conization seems to be a protective factor in decreasing recurrence risk, assisting clinicians in predicting survival outcomes for patients with early-stage cervical cancer. It may potentially aid in selecting suitable candidates for minimally invasive surgery in clinical practice.

RESUMO

CONTEXT.­: Noninvasive self-sampling is a convenient option that may be highly accepted by women for home-based detection, which could increase the screening rate for cervical cancer (CC) and reduce its incidence and mortality. OBJECTIVE.­: To compare the distribution of high-risk human papillomavirus (hr-HPV) between the vulva and cervix and to explore the clinical value of vulvar HPV detection in CC screening. DESIGN.­: The study was nested within a clinical trial on recombinant HPV 9-valent vaccine for women ages 20 to 45 years. Women with paired vulvar and cervical specimens were included and received cytology and HPV detection. The consistency of HPV detection between vulvar and cervical specimens was evaluated using Cohen κ statistics. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were used to evaluate the diagnostic accuracy of primary CC screening. The primary end points were cervical intraepithelial neoplasia (CIN) grade 2/3 or worse (CIN2+/3+). RESULTS.­: A total of 7999 women were enrolled, and 83/33 cases were diagnosed as CIN2+/CIN3+. The HPV-positive rate in vulvar specimens (1785 of 7999; 22.32%) was higher than that in cervical specimens (1390 of 7999; 17.38%), and there were no significant differences in the distribution of hr-HPV genotypes between the vulva and cervix in patients with CIN2+/CIN3+. Vulva-based HPV primary screening showed sensitivity, specificity, PPV, and NPV comparable to those for cervix-based HPV primary CC screening in the detection of CIN3+. CONCLUSIONS.­: The distribution of vulvar and cervical HPV was similar in patients with CIN2+/CIN3+. Vulva-based HPV primary CC screening had acceptable diagnostic efficacy and might be used as a modality for primary CC screening.

RESUMO

Background: POEMS syndrome is a rare and complex plasma cell disorder characterized by polyneuropathy, organomegaly, endocrinopathy, high M protein levels, and skin changes. Understanding of POEMS syndrome has advanced rapidly since the 21st century. This study aims to summarize and evaluate the research status of POEMS syndrome in the past 23 years through a bibliometric and visualization analysis, and identify research focuses and emerging hotspots for the future. Methods: POEMS syndrome-related articles published between January 1, 2000, and March 8, 2023, were systematically retrieved from the Web of Science Core Collection. Data processing and visualization analysis were carried out using a combination of R software, HistCite, VOSviewer, and CiteSpace. Results: Since entering the 21st century, 3677 authors from 1125 institutions in 68 countries/regions have published 830 original and review articles on POEMS syndrome in 408 journals so far, among which the USA, Japan, and China published the most articles, and Mayo Clinic, Udice French Research Universities, and Peking Union Medical College listed the top three most prolific institutions. However, collaborative research across countries and groups in the study of POEMS syndrome remain significantly limited. Angela Dispenzieri ranked first in POEMS syndrome research from every aspect of authors, producing the most papers and contributing the most-cited article, followed by Satoshi Kuwabara and Sonoko Misawa. Internal medicine was the most productive journal on POEMS syndrome. "endothelial growth factor" was the keyword with the highest occurrence except for "POEMS syndrome", and "bevacizumab", "lenalidomide", "dexamethasone", and "management" were recognized as emerging topics. Conclusion: This study utilized bibliometric and visualization analysis to systematically summarize the research of POEMS syndrome in the first two decades of the 21st century, offering a data-based and objective perspective on the field of POEMS syndrome and guiding researchers in the identification of novel research directions.

RESUMO

The activating protein-1 (AP-1) transcription factors (TFs) have been associated with many different cancer types and are promising therapeutic targets in logical malignancies. However, the mechanisms of their role in multiple myeloma (MM) remain elusive. The present study determined and compared the mRNA and protein expression levels of the AP-1 family member JunB in CD138+ mononuclear cells from MM patients and healthy donors. Herein, we investigated the effect of T-5224, an inhibitor of JUN/AP-1, on MM. We found that the cytotoxicity of T-5224 toward myeloma is due to its ability to induce cell apoptosis, inhibit proliferation, and induce cell cycle arrest by increasing the levels of cleaved caspase3/7 and concomitantly inhibiting the IRF4/MYC axis. We also noticed that siJunB-mediated deletion of JunB/AP-1 enhanced MM cell apoptosis and affected cell proliferation. The software PROMO was used in the present study to predict the AP-1 TF that may bind the promoter region of IRF4. We confirmed the correlation between JunB/AP-1 and IRF4. Given that bortezomib (BTZ) facilitates IRF4 degradation in MM cells, we applied combination treatment of BTZ with T-5224. T-5224 and BTZ exerted synergistic effects, and T-5224 reversed the effect of BTZ on CD138+ primary resistance in MM cells, in part due to suppression of the IRF4/MYC axis. Our results suggest that targeting AP-1 TFs is a promising therapeutic strategy for MM. Additionally, targeting both AP-1 and IRF4 with T-5224 may be a synergistic therapeutic strategy for this clinically challenging subset of MM.

RESUMO

Introduction: Triple-negative breast cancer (TNBC) is a highly aggressive subtype with a poor prognosis. Current single-agent checkpoint therapy has limited effectiveness in TNBC patients. In this study, we developed doxorubicin-loaded platelet decoys (PD@Dox) for chemotherapy and induction of tumor immunogenic cell death (ICD). By combining PD-1 antibody, PD@Dox has the potential to enhance tumor therapy through chemoimmunotherapy in vivo. Methods: Platelet decoys were prepared using 0.1% Triton X-100 and co-incubated with doxorubicin to obtain PD@Dox. Characterization of PDs and PD@Dox was performed using electron microscopy and flow cytometry. We evaluated the properties of PD@Dox to retain platelets through sodium dodecyl sulfate-polyacrylamide gel electrophoresis, flow cytometry, and thromboelastometry. In vitro experiments assessed drug-loading capacity, release kinetics, and the enhanced antitumor activity of PD@Dox. The mechanism of PD@Dox was investigated through cell viability assays, apoptosis assays, Western blot analysis, and immunofluorescence staining. In vivo studies were performed using a TNBC tumor-bearing mouse model to assess the anticancer effects. Results: Electron microscopic observations confirmed that platelet decoys and PD@Dox exhibited a round shape similar to normal platelets. Platelet decoys demonstrated superior drug uptake and loading capacity compared to platelets. Importantly, PD@Dox retained the ability to recognize and bind tumor cells. The released doxorubicin induced ICD, resulting in the release of tumor antigens and damage-related molecular patterns that recruit dendritic cells and activate antitumor immunity. Notably, the combination of PD@Dox and immune checkpoint blockade therapy using PD-1 antibody achieved significant therapeutic efficacy by blocking tumor immune escape and promoting ICD-induced T cell activation. Conclusion: Our results suggest that PD@Dox, in combination with immune checkpoint blockade therapy, holds promise as a potential strategy for TNBC treatment.

RESUMO

Chemoresistance to paclitaxel (PTX) is one of the main reasons for treatment failure and poor prognosis in patients with advanced ovarian cancer. Therefore, it is imperative to explore the mechanisms related to chemotherapy resistance in ovarian cancer to find potential therapeutic targets. Circular RNAs (circRNAs) play important roles in cancer development and progression. However, their biological functions and clinical significance in ovarian cancer have not been fully elucidated. Therefore, in this study, we aimed to investigate the function and underlying mechanism of hsa_circ_0002782 (circSLC39A8), identified by circRNA sequencing, in regulating PTX resistance. The effects of circSLC39A8 on PTX resistance was assessed by cell viability, colony formation, flow cytometry assays and an in vivo subcutaneous xenografted tumor mouse model. RNA immunoprecipitation and dual-luciferase reporter assays were performed to verify the interaction between circSLC39A8 and the miR-185-5p/BMF signal axis. We found that circSLC39A8 was downregulated in PTX-resistant ovarian cancer cells and tissues, and its low expression was associated with poor prognosis. Biologically, circSLC39A8 knockdown promoted PTX resistance in vitro and in vivo, while circSLC39A8 overexpression showed the opposite effect. Mechanistically, circSLC39A8, acting as an endogenous sponge for miR-185-5p, could relieve the inhibition of miR-185-5p on the expression of its downstream target, BMF; thus enhancing the sensitivity of ovarian cancer to PTX. Our findings demonstrate that circSLC39A8 can promote PTX sensitivity by regulating the miR-185-5p/BMF axis. This may be a valuable prognostic biomarker and a promising therapeutic target for patients with ovarian cancer.

RESUMO

BACKGROUND: USP51 is a deubiquitinase (DUB), that is involved in diverse cellular processes. Accumulating evidence has demonstrated that USP51 contributes to cancer development. However, its impact on non-small cell lung carcinoma (NSCLC) cell malignancy is largely unknown. METHODS: In this study, we performed bioinformatics analysis on a dataset from The Cancer Genome Atlas to determine the association between USP51 and cell stemness marker expression in NSCLC patients. RT‒qPCR, Western blotting, and flow cytometry were performed to examine the effects of USP51 depletion on stemness marker expression. Colony formation and tumor sphere formation assays were used to assess the stemness of NSCLC cells. A cycloheximide chase time-course assay and a polyubiquitination assay were carried out to analyze the effects of USP51 on the TWIST1 protein level. TWIST1 was overexpressed in USP51 knockdown NSCLC cells to determine whether TWIST1 is required. The effect of USP51 on the in vivo growth of NSCLC cells was tested through subcutaneous injections in mice. RESULTS: We found that USP51 deubiquitinates TWIST1, which is significantly upregulated in the tissues of patients with NSCLC and is closely associated with poor prognosis. USP51 expression was positively correlated with the expression of stemness marker CD44, SOX2, NANOG, and OCT4 in NSCLC patients. USP51 depletion attenuated mRNA, protein, and cell surface expression of stemness markers and the stemness of NSCLC cells. Ectopic USP51 expression potentiated the stability of the TWIST1 protein by attenuating its polyubiquitination. In addition, TWIST1 re-expression in NSCLC cells reversed the inhibitory effect of USP51 knockdown on cell stemness. Furthermore, the in vivo results confirmed the suppressive effect of USP51 depletion on NSCLC cell growth. CONCLUSIONS: Our results show that USP51 maintains the stemness of NSCLC cells by deubiquitinating TWIST1. Knocking it down reduces both cell stemness and growth of NSCLC cells.

RESUMO

Multiple myeloma (MM) is a malignant and incurable disease. Chemotherapy is currently the primary treatment option for MM. However, chemotherapeutic drugs can interrupt treatment because of serious side effects. Therefore, development of novel therapeutics for MM is essential. In this study, we designed and constructed an innovative nanoparticle-based drug delivery system, P-R@Ni3P-BTZ, and investigated its feasibility, effectiveness, and safety both in vitro and in vivo. P-R@Ni3P-BTZ is a nanocomposite that consists of two parts: (1) the drug carrier (Ni3P), which integrates photothermal therapy (PTT) with chemotherapy by loading bortezomib (BTZ); and (2) the shell (P-R), a CD38 targeting peptide P-modified red blood cell membrane nanovesicles. In vitro and in vivo, it was proven that P-R@Ni3P-BTZ exhibits remarkable antitumor effects by actively targeting CD38 + MM cells. P-R@Ni3P-BTZ significantly induces the accumulation of intracellular reactive oxygen species (ROS) and increases the apoptosis of MM cells, which underlies the primary mechanism of its antitumor effects. In addition, P-R@Ni3P exhibits good biocompatibility and biosafety, both in vitro and in vivo. Overall, P-R@Ni3P-BTZ is a specific and efficient MM therapeutic method.

RESUMO

Background: Metabolic syndrome (MetS) has been associated with digestive system diseases, and recent observational studies have suggested an association between MetS and cholelithiasis. However, the causal relationship between them remains unclear. This study aimed to assess the causal effect of MetS on cholelithiasis using Mendelian randomization (MR) analysis. Methods: Single nucleotide polymorphisms (SNPs) of MetS and its components were extracted from the public genetic variation summary database. The inverse variance weighting method (IVW), weighted median method, and MR-Egger regression were used to evaluate the causal relationship. A sensitivity analysis was performed to ensure the stability of the results. Results: IVW showed that MetS increased the risk of cholelithiasis (OR = 1.28, 95% CI = 1.13-1.46, P = 9.70E-05), and the weighted median method had the same result (OR = 1.49, 95% CI = 1.22-1.83, P = 5.68E-05). In exploring the causal relationship between MetS components and cholelithiasis, waist circumference (WC) was significantly associated with cholelithiasis. IVW analysis (OR = 1.48, 95% CI = 1.34-1.65, P = 1.15E-13), MR-Egger regression (OR = 1.62, 95% CI = 1.15-2.28, P = 0.007), and weighted median (OR = 1.73, 95% CI = 1.47-2.04, P = 1.62E-11) all found the same results. Conclusion: Our study indicated that MetS increases the incidence of cholelithiasis, especially in MetS patients with abdominal obesity. Control and treatment of MetS can effectively reduce the risk of gallstone formation.

RESUMO

The frequency of exertional heat stroke (EHS) increases with the gradual elevation of global temperatures during summer. Acute kidney injury (AKI) is a common complication of EHS, and its occurrence often indicates the worsening of a patient's condition or a poor prognosis. In this study, a rat model of AKI caused by EHS was established, and the reliability of the model was evaluated by HE staining and biochemical assays. The expression of kidney tissue proteins in the EHS rats was analyzed using label-free liquid chromatography-tandem mass spectrometry. A total of 3,129 differentially expressed proteins (DEPs) were obtained, and 10 key proteins were finally identified, which included three upregulated proteins (Ahsg, Bpgm, and Litaf) and seven downregulated proteins (medium-chain acyl-CoA synthetase 2 (Acsm2), Hadha, Keg1, Sh3glb1, Eif3d, Ambp, and Ddah2). The qPCR technique was used to validate these 10 potential biomarkers in rat kidney and urine. In addition, Acsm2 and Ahsg were double-validated by Western blotting. Overall, this study identified 10 reliable biomarkers that may provide potential targets for the treatment of AKI caused by EHS.

RESUMO

Early detection and timely treatment is the key to improving the prognosis of rectal cancer. Lymph node metastasis is one of the reasons for the poor prognosis of rectal cancer, especially early-stage rectal cancer. In this study, we developed a nomogram based on log odds of positive lymph nodes (LODDS) to predict cancer-specific survival (CSS) in patients with T1 rectal cancer. We included 1934 patients from the Surveillance, Epidemiology, and End Results (SEER) database and divided them into a training cohort and an in-validation cohort. 140 patients from our hospital formed the ex-validation cohort. Multivariate Cox regression analysis indicated that age, sex, grade, and M stage were independent prognostic factors for CSS. LODDS showed better predictive ability than the N stage and PLNs (positive lymph nodes) and was further selected as an independent prognostic factor for the construction of the nomogram. The C-index of the nomogram was 0.743, 0.756, and 0.876 in the training, in-validation, and ex-validation cohorts, respectively. The AUC values of the three cohorts were 0.750, 0.703, and 0.958 at 3 years and 0.731, 0.678, and 0.783 at 5 years. The calibration curves and DCA demonstrated the nomogram's excellent performance. In conclusion, we developed and validated a new nomogram based on LODDS that can effectively predict CSS at 3 and 5 years for patients with T1 rectal cancer.

RESUMO

BACKGROUND: There has been great progress in the use of endoscopic ultrasound (EUS)-guided drainage in acute pancreatitis patients using a novel lumen-apposing metal stent (LAMS) in the last decade, but some patients experience bleeding. Our research analyzed the preprocedural risk factors for bleeding. METHODS: From July 13, 2016 to June 23, 2021, we retrospectively analyzed all patients who received endoscopic drainage by the LAMS in our hospital. Univariate and multivariate statistical analyses were used to identify the independent risk factors. We plotted ROC curves based on the independent risk factors. RESULTS: A total of 205 patients were analyzed and 5 patients were excluded. A total of 200 patients were included in our research. Thirty (15%) patients presented with bleeding. In the multivariate analysis, computed tomography severity index score (CTSI) score [odds ratio (OR), 2.66; 95% CI: 1.31-5.38; P = 0.007], positive blood cultures [odds ratio (OR), 5.35; 95% CI: 1.31-21.9; P = 0.02], and Acute Physiology and Chronic Health Evaluation II (APACHE II) score [odds ratio (OR), 1.14; 95% CI: 1. 01-1.29; P = 0.045] were associated with bleeding. The area under the ROC curve of the combined predictive indicator was 0.79. CONCLUSION: Bleeding in endoscopic drainage by the LAMS is significantly associated with the CTSI score, positive blood cultures, and APACHE II score. This result could help clinicians make more appropriate choices.

RESUMO

What is already known about this topic?: The effective implementation of cervical cancer examination programs requires improved cervical cancer screening coverage and quality. What is added by this report?: The detection rate of ≥high-grade squamous intraepithelial lesions (HSIL) in 6 hospitals was 19.6%. Not having undergone screening in the last 5 years and abnormal screening results had a negative association with detection of ≥HSIL, and abnormal screening results would increase the risk of detection by 75% compared with normal screening results. Additionally, low-grade, high-grade, and cancer of colposcopic impression were associated with a higher risk for detecting ≥HSIL. What are the implications for public health practice?: It is essential to disseminate health knowledge about cervical cancer control to women in order to increase their awareness and screening rates. Additionally, it is necessary to further strengthen the training of professional staff to improve the quality of cervical cancer prevention, including screening, colposcopic examination, and follow-up for target female populations.

RESUMO

Previous studies have shown the potential of immunogenic cell death-related modalities in myeloma. The significance of IL5RA in myeloma and immunogenic cell death remains unknown. We analyzed IL5RA expression, the gene expression profile, and secretory protein genes related to IL5RA level using GEO data. Immunogenic cell death subgroup classification was performed using the ConsensusClusterPlus and pheatmap R package. Enrichment analyses were based on GO/KEGG analysis. After IL5RA-shRNA transfection in myeloma cells, cell proliferation, apoptosis, and drug sensitivity were detected. P < 0.05 was considered statistically significant. IL5RA was upregulated in myeloma and progressed smoldering myeloma. We observed enrichment in pathways such as the PI3K-Akt signaling pathway, and Natural killer cell mediated cytotoxicity in the high-IL5RA group. IL5RA was also closely associated with secretory protein genes such as CST6. We observed the enrichment of cellular apoptosis and hippo signaling pathway on differential genes in the immunogenic cell death cluster. Furthermore, IL5RA was associated with immune infiltration, immunogenic cell death-related genes, immune-checkpoint-related genes, and m6A in myeloma. In vitro and in vivo experiments showed the involvement of IL5RA in apoptosis, proliferation, and drug resistance of myeloma cells. IL5RA shows the potential to be an immunogenic cell death-related predictor for myeloma.

RESUMO

To evaluate the effect of DH3-human papillomavirus (HPV) partial genotyping for risk stratification in cervical cancer screening, we conducted a post hoc analysis within a retrospective cohort of 7263 Chinese women aged 21-71 years who participated in population-based screening. The residual cytological samples at baseline were retested with DH3-HPV and Hybrid Capture 2 (HC2) assay after 3-year follow-up. Risk values with 95% confidence intervals (CIs) of cervical intraepithelial neoplasia (CIN) grade 3/2 or worse (CIN3+/CIN2+) were estimated based on HPV and cytology results. The report complies with the STROBE statement. Across every cytological result, risk estimates obtained from DH3-HPV and HC2 were similar or almost identical. By DH3-HPV partial genotyping, risks of CIN3+/CIN2+ were invariably higher for HPV16/18 than other high-risk HPV (hrHPV). Among women with normal cytology, immediate CIN3+ risks were 8.16% (95% CI = 4.19%-15.28%) for HPV16/18 positive and 0.48% (95% CI = 0.13%-1.73%) for other hrHPV positive. Among women with any abnormal cytology, immediate CIN3+ risks were 33.33% (95% CI = 22.24%-46.64%) for HPV16/18, and 13.33% (95% CI = 8.37%-20.56%) for other hrHPV. Among 5840 women completed 3-year follow-up, the cumulative CIN3+ risk was 25.56% (95% CI = 18.91%-33.59%) for HPV16/18 and 8.22% (95% CI = 6.02%-11.13%) for other hrHPV. Women with an HPV-negative result with DH3-HPV or HC2 test had very low cumulative 3-year CIN3+ risk (0.06%, 95% CI = 0.02%-0.17%), which was about one-tenth of women with normal cytology at baseline (0.62%, 95% CI = 0.45%-0.86%). Similar patterns were observed for the endpoint of CIN2+. These findings suggest that partial genotyping of DH3-HPV performs well in risk stratification, which can better balance the benefits and harms of cervical cancer screening.

RESUMO

Background: Existing guidelines recommend endoscopic treatment within 12 h or 12-24 h for patients with esophagogastric variceal bleeding (EGVB) in cirrhosis. In addition, research findings on the optimal time for endoscopy are inconsistent. Aim: The aim of this study was to investigate the relationship between the timing of endoscopy and clinical outcomes in cirrhotic patients with EGVB and to analyze the risk factors for the composite outcomes after endoscopic treatment. Methods: From January 2019 to June 2020, 456 patients with cirrhotic EGVB who underwent endoscopy were matched by a 1:1 propensity score. Finally, 266 patients were divided into two groups, including 133 patients within 12 h (urgent endoscopy group) of admission and after 12 h (non-urgent endoscopy group). Baseline data and clinical outcomes were compared. Logistic regression model analysis was used to determine risk factors for 30 days rebleeding and mortality. Results: In 266 patients, the overall 30 days rebleeding rate and mortality were 10.9% (n = 29) and 3.4% (n = 9), respectively. Patients who underwent endoscopic treatment within 12 h had significantly higher 30 days rebleeding outcomes than those who underwent treatment beyond 12 h (15 vs. 6.8%, p = 0.003). However, 30 days mortality did not differ significantly between the two groups (3 vs. 3.8%, p = 0.736). Logistic regression analysis showed that age and shock on admission were independent risk factors for the composite outcome of 30 days rebleeding and mortality in patients with EGVB. Conclusion: The 30 days rebleeding rate in patients with cirrhotic EGVB treated with urgent endoscopy was significantly higher than that in patients treated with non-urgent endoscopy, but there was no significant difference in 30 days mortality.
