Predictive value of PAR and PNI for the acute complicated course of pediatric acute hematogenous osteomyelitis

Abstract Objective Platelet to albumin ratio (PAR) and prognostic nutritional index (PNI) are potential indicators for evaluating nutritional and inflammatory status. This study aimed to examine the relationship between PAR and PNI and the acute complicated course of acute hematogenous osteomyelitis (AHO). Methods AHO patients were divided into the simple course group and the acute complicated course group. The patient's gender, age, site of infection, body temperature, laboratory results, and pathogen culture results were collected and compared. Multivariate logistic regression analysis was used to determine the independent risk factors of the acute complicated course group. The receiver operating characteristic curve was applied to determine the optimal cut-off value. Results In total, 101 AHO patients with a median age of 7.58 years were included. There were 63 cases (62.4 %) in the simple course group and 38 cases (37.6 %) in the complicated course group. Binary logistic regression analysis revealed that PAR and PNI were independent risk factors for predicting the acute complicated course of AHO (p = 0.004 and p < 0.001, respectively). Receiver operating characteristic curve analysis demonstrated that the combination of PAR and PNI had an area under the curve of 0.777 (95 % CI: 0.680-0.873, p < 0.001) with a cut-off value of 0.51. Conclusions The incidence of acute complicated courses was significantly higher in patients with high PAR and low PNI. A combined factor greater than 0.51, derived from PAR and PNI measurements within 24 h of admission, may be useful for predicting AHO patients who are likely to develop severe disease.

A clinicopathological study of histomorphological differentiation and staging of lymph node metastasis in periampullary carcinoma

Background: The periampullary region is an anatomically and histologically complex area that is prone towards malignant transformation. Malignancies in this region have increased in incidence in the last few decades. Classifying these malignancies has become crucial for prognosis and treatment. With the pancreato-biliary type being more aggressive as compared to the intestinal type. Lymph node metastasis and lymph node ratio also aid in prognostication. Methods: This prospective descriptive study was conducted over one year from August 2022 on 30 patients diagnosed with periampullary tumors who underwent pancreatoduodenectomy and biopsy. Histopathological classification and prognostic factors were analyzed based on Kimura et al classification. Results: The study included 18 males and 12 females with a mean age of 53.47 years. The origin of the tumor was the head of the pancreas in 66.66% (n=20) of the patients. Adenocarcinoma was the most common histological type. The pancreato-biliary type of adenocarcinoma was more aggressive than the intestinal type when primary tumor size and staging were compared. Conclusions: Periampullary carcinomas are difficult to classify. Kimura et al classification is an important classification system that helps in the treatment and prognostication of the patient. The pancreato-biliary type of adenocarcinoma is more aggressive as compared to the intestinal type. Lymph node metastasis and lymph node ratio are also important prognostic factors.

Fibrilación auricular de novo en síndrome coronario agudo / Atrial fibrillation de novo in acute coronary syndrome

Resumen Una de las complicaciones durante un evento de síndrome coronario agudo es la presencia de arritmias. Dentro de ellas, las de tipo supraventricular, en especial fibrilación auricular, acarrea un mal pronóstico tanto a corto como a largo plazo y es la causa de situaciones como evento vascular cerebral, arritmias ventriculares y aumento de la mortalidad. Dicha arritmia tiende a aparecer en cierto grupo de población con particulares factores de riesgo durante el evento índice en aproximadamente 10% de los casos. Un tratamiento apropiado en el momento de su aparición, gracias al uso de fármacos que modulan la frecuencia cardiaca, el ritmo y el manejo anticoagulante en los grupos más vulnerables conllevará un desenlace menos sombrío para estos pacientes.

Abstract One of the complications during an acute coronary syndrome event is the presence of arrhythmias. Among them, those of the supraventricular type, especially atrial fibrillation, carry a poor prognosis both in the short and long term, being the cause of situations such as cerebrovascular event, ventricular arrhythmias, and increased mortality. The arrhythmia tends to appear in a certain population group with particular risk factors during the index event in approximately 10% of cases. Appropriate treatment at the time of its onset, thanks to the use of drugs that modulate heart rate, rhythm, and anticoagulant management in the most vulnerable groups, will lead to a less bleak outcome for these patients.

Recurrence factors in patients with cutaneous melanoma and positive sentinel lymph node treated in a single reference unit in Buenos Aires / Factores de recurrencia en pacientes con melanoma cu táneo y ganglio centinela positivo

Abstract Introduction : Although therapeutic advances have improved results of cutaneous melanoma (CM), senti nel node-positive patients still have substantial risk to develop recurrent disease. We aim to investigate prog nostic indicators associated with disease recurrence in positive-sentinel lymph node biopsy (SLNB) patients in a Latin-American population. Methods : Retrospective analysis of CM patients and positive-SLNB (2010-2020). Patients were divided into two groups: Group A (completion lymph node dissection, CLND), Group B (active surveillance, AS). Association of demographics, tumor data and SLN features with recurrence-free (RFS), distant metastases-free (DMFS) and melanoma specific (MSS) survival was analyzed. Results : Of 205 patients, 45 had a positive SLNB; 27(60%) belonged to Group A and 18(40%) to Group B. With a median follow-up of 36 months, 16 patients (12 in Group A and 4 in Group B) developed recurrent dis ease and estimated 5-yr RFS at any site was 60% (CI95%, 0.39 - 0.77) (44.5% in CLND group vs. 22% in AS group; P = 0.20). Estimated 5-yr DMFS and MSS: 65% (CI 95%, 0.44 - 0.81) and 73% (CI 95%, 0.59 - 0.89) with no differ ences between groups (p = 0.41 and 0.37, respectively). Independent predictors of poorer MSS were extranodal extension (ENE) and MaxSize > 2 mm of melanoma deposit in SLN. Factors independently associated with DMFS: Breslow depth > 2 mm, ENE, number (≥ 2) of posi tive SN and CLND status. Conclusion : Primary tumor and SN features in mela noma provide important prognostic information that help optimize prognosis and clinical management. AS is now the preferred approach for most positive-SLNB CM patients.

Resumen Introducción : Si bien los avances terapéuticos han permitido mejorar los resultados del melanoma cutáneo (MC), los pacientes con ganglio centinela positivo (BGCP) aún tienen riesgo elevado de desarrollar recurrencia de la enfermedad. Nuestro objetivo fue investigar in dicadores pronósticos asociados a dicho evento en una población latinoamericana. Métodos : Análisis retrospectivo de pacientes con MC y BGCP entre 2010-2020. Los pacientes se dividieron en 2 grupos: Grupo A (linfadenectomía terapéutica) y Grupo B (Vigilancia activa, VA). Se analizaron datos demográficos, tumorales y características del GC junto con sobrevida-libre de recurrencia (SLR), libre de metástasis a distancia (SLMD) y específica de melanoma (SEM). Resultados : De 205 pacientes, 45 presentaron BGCP; 27 (60%) perteneció al Grupo A y 18 (40%) al Grupo B. Con una mediana de seguimiento de 36 meses, 16 pa cientes (12 en Grupo A y 4 en Grupo B) desarrollaron enfermedad recurrente con una SLR a 5 años de 60% (IC95%: 0.39-0.77) (44.5% en Grupo B vs. 22% en Grupo A; P = 0.20). Las SLMD y SEM estimadas a 5 años fueron de 65% (CI 95%, 0.44 - 0.81) y 73% (CI 95%, 0.59 - 0.89) sin diferencias entre ambos grupos (p = 0.41 y 0.37, respec tivamente). Los predictores independientes de peor SEM fueron: extensión extranodal (ENE) y MaxSize > 2mm de depósito tumoral en GC. Los factores asociados de forma independiente con SLMD fueron Breslow >2mm, ENE, número (≥ 2) de GC positivos y el status (positividad) de la linfadenectomía. Conclusión : Características del tumor primario y del GC brindan información importante que ayuda a optimi zar el pronóstico y manejo clínico de los pacientes con MC. La VA es actualmente el abordaje de elección para la mayoría de los pacientes con BGCP.

Prediction of Prognostic Features Based on Neutrophil-Related Genes for Lung Squamous Cell Carcinoma Reveals Immune Landscape and Drug Candidates

ABSTRACT Background: Since to the prognosis of lung squamous cell carcinoma is generally poor, there is an urgent need to innovate new prognostic biomarkers and therapeutic targets to improve patient outcomes. Objectives: Our goal was to develop a novel multi-gene prognostic model linked to neutrophils for predicting lung squamous cell carcinoma prognosis. Methods: We utilized messenger RNA expression profiles and relevant clinical data of lung squamous cell carcinoma patients from the Cancer Genome Atlas database. Through K-means clustering, least absolute shrinkage and selection operator regression, and univariate/multivariate Cox regression analyses, we identified 12 neutrophil-related genes strongly related to patient survival and constructed a prognostic model. We verified the stability of the model in the Cancer Genome Atlas database and gene expression omnibus validation set, demonstrating the robust predictive performance of the model. Results: Immunoinfiltration analysis revealed remarkably elevated levels of infiltration for natural killer cells resting and monocytes in the high-risk group compared to the low-risk group, while macrophages had considerably lower infiltration in the high risk group. Most immune checkpoint genes, including programmed cell death protein 1 and cytotoxic T-lymphocyte-associated antigen 4, exhibited high expression levels in the high risk group. Tumor immune dysfunction and exclusion scores and immunophenoscore results suggested a potential inclination toward immunotherapy in the "RIC" version V2 revised high risk group. Moreover, prediction results from the CellMiner database revealed great correlations between drug sensitivity (e.g., Vinorelbine and PKI-587) and prognostic genes. Conclusion: Overall, our study established a reliable prognostic risk model that possessed significant value in predicting the overall survival of lung squamous cell carcinoma patients and may guide personalized treatment strategies.

FRZB: a potential prognostic marker for head and neck squamous cell carcinoma

Head and neck squamous cell carcinoma (HNSCC) is the sixth most common malignancy worldwide, with approximately 600,000 new cases each year. A small number of HNSCCs are caused by human papillomavirus (HPV) infection. Frizzled related protein (FRZB) has been reported in many inflammatory diseases and cancers, but it is yet unclear how FRZB affects HNSCC, as well as its role and underlying mechanism. TIMER2 database was utilized to evaluate FRZB expression in cancer tissues, and FRZB expression in HNSCC tissues was confirmed by samples obtained from Gene Expression Omnibus. To identify whether FRZB could be used as a prognostic predictor, we performed univariate and multivariate Cox regression analyses. FRZB co-expression profile was explored using the LinkedOmics database, then Kyoto Encyclopedia of Genes and Genomes and Gene Ontology enrichment analyses were performed for these FRZB-related genes in HNSCC samples. Lasso regression analysis was subsequently used to screen for prognostic variables, and we determined the infiltration of immune cells in HNSCC patients to clarify the influence of FRZB on tumor immune microenvironment. At last, we assessed the association between FRZB expression and immune checkpoint gene, and compared the sensitivity of common chemotherapeutic agents. In this study, we found that FRZB was dysregulated in HNSCC tumor tissues and had a relationship with clinical parameters. The reliability and independence of FRZB as a factor in determining a patient's prognosis for HNSCC was also established. Additional investigation revealed that FRZB was linked to common immune checkpoint genes and may be implicated in immune infiltration.

An extensive analysis of the prognostic and immune role of FOXO1 in various types of cancer

Forkhead Box O1 (FOXO1) has been reported to play important roles in many tumors. However, FOXO1 has not been studied in pan-cancer. The purpose of this study was to reveal the roles of FOXO1 in pan-cancer (33 cancers in this study). Through multiple public platforms, a pan-cancer analysis of FOXO1 was conducted to obtained FOXO1 expression profiles in various tumors to explore the relationship between FOXO1 expression and prognosis of these tumors and to disclose the potential mechanism of FOXO1 in these tumors. FOXO1 was associated with the prognosis of multiple tumors, especially LGG (low grade glioma), OV (ovarian carcinoma), and KIRC (kidney renal clear cell carcinoma). FOXO1 might play the role of an oncogenic gene in LGG and OV, while playing the role of a cancer suppressor gene in KIRC. FOXO1 expression had a significant correlation with the infiltration of some immune cells in LGG, OV, and KIRC. By combining FOXO1 expression and immune cell infiltration, we found that FOXO1 might influence the overall survival of LGG through the infiltration of myeloid dendritic cells or CD4+ T cells. Functional enrichment analysis and gene set enrichment analysis showed that FOXO1 might play roles in tumors through immunoregulatory interactions between a lymphoid and a non-lymphoid cell, TGF-beta signaling pathway, and transcriptional misregulation in cancer. FOXO1 was associated with the prognosis of multiple tumors, especially LGG, OV, and KIRC. In these tumors, FOXO1 might play its role via the regulation of the immune microenvironment.

CLCA1 is Poorly Expressed in Stomach Adenocarcinoma and Correlates with Immune Infiltration / CLCA1 se Expresa Deficientemente en el Adenocarcinoma de Estómago y se Correlaciona con la Infiltración Inmune

SUMMARY: Calcium-activated chloride channel regulator 1 (CLCA1) is associated with cancer progression. The expression and immunologic function of CLCA1 in stomach adenocarcinoma (STAD) remain unclear. In this investigation, the expression of CLCA1 in STAD tissues and its involvement in the progression and immune response of STAD were examined using databases such as cBioPortal, TISIDB, and UALCAN. In order to validate the expression level of CLCA1 protein in gastric adenocarcinoma, thirty clinical tissue specimens were gathered for immunohistochemical staining. The findings indicated a downregulation of CLCA1 in STAD patients, which was correlated with race, age, cancer grade, Helicobacter pylori infection, and molecular subtype. Through the examination of survival analysis, it was identified that diminished levels of CLCA1 within gastric cancer cases were linked to decreased periods of post-progression survival (PPS), overall survival (OS), and first progression (FP) (P<0.05). The CLCA1 mutation rate was lower in STAD, but the survival rate was higher in the variant group. The correlation between the expression level of CLCA1 and the levels of immune infiltrating cells in STAD, as well as the immune activating molecules, immunosuppressive molecules, MHC molecules, chemokines, and their receptor molecules, was observed. Gene enrichment analysis revealed that CLCA1 may be involved in STAD progression through systemic lupus erythematosus (SLE), proteasome, cell cycle, pancreatic secretion, and PPAR signaling pathways. In summary, CLCA1 is anticipated to function as a prognostic marker for patients with STAD and is linked to the immunization of STAD.

El regulador 1 del canal de cloruro activado por calcio (CLCA1) está asociado con la progresión del cáncer. La expresión y la función inmunológica de CLCA1 en el adenocarcinoma de estómago (STAD) aún no están claras. En esta investigación, se examinó la expresión de CLCA1 en tejidos STAD y su participación en la progresión y respuesta inmune de STAD utilizando bases de datos como cBioPortal, TISIDB y UALCAN. Para validar el nivel de expresión de la proteína CLCA1 en el adenocarcinoma gástrico, se recolectaron treinta muestras de tejido clínico para tinción inmunohistoquímica. Los hallazgos indicaron una regulación negativa de CLCA1 en pacientes con STAD, que se correlacionó con la raza, la edad, el grado del cáncer, la infección por Helicobacter pylori y el subtipo molecular. Mediante el examen del análisis de supervivencia, se identificó que los niveles reducidos de CLCA1 en los casos de cáncer gástrico estaban relacionados con períodos reducidos de supervivencia posterior a la progresión (PPS), supervivencia general (OS) y primera progresión (FP) (P <0,05). La tasa de mutación CLCA1 fue menor en STAD, pero la tasa de supervivencia fue mayor en el grupo variante. Se observó la correlación entre el nivel de expresión de CLCA1 y los niveles de células inmunes infiltrantes en STAD, así como las moléculas activadoras inmunes, moléculas inmunosupresoras, moléculas MHC, quimiocinas y sus moléculas receptoras. El análisis de enriquecimiento genético reveló que CLCA1 puede estar involucrado en la progresión de STAD a través del lupus eritematoso sistémico (LES), el proteasoma, el ciclo celular, la secreción pancreática y las vías de señalización de PPAR. En resumen, se prevé que CLCA1 funcione como un marcador de pronóstico para pacientes con STAD y está vinculado a la inmunización de STAD.

Testes de Triagem Prevendo Metástase de Câncer na Etiologia do Derrame Pericárdico: HALP Score e PNI / Screening Tests Predicting Cancer Metastasis in the Etiology of Pericardial Effusion: HALP Score and PNI

Resumo Fundamento: A triagem do câncer é absolutamente necessária em pacientes com derrame pericárdico, pois o câncer é uma das doenças mais graves em sua etiologia. Estudos anteriores indicaram que o índice de inflamação imunológica sistêmica (IIS), o índice prognóstico nutricional (PNI) e o escore de hemoglobina, albumina, linfócitos e plaquetas (HALP) podem ser escores relacionados ao câncer. Objetivos: Este estudo foi iniciado considerando que esses sistemas de pontuação poderiam prever o câncer na etiologia de pacientes com derrame pericárdico. Métodos: Os pacientes submetidos à pericardiocentese entre 2006 e 2022 foram analisados retrospectivamente. A pericardiocentese foi realizada em um total de 283 pacientes com derrame pericárdico ou tamponamento cardíaco de moderado a grande no período especificado. Os índices de HALP, PNI e IIS foram calculados do sangue venoso periférico retirado antes do procedimento de pericardiocentese. O nível de significância estatística foi aceito em p<0,05. Resultados: O escore HALP foi de 0,173 (0,125-0,175) em pacientes com câncer. Detectou-se que em pacientes não oncológicos o escore foi de 0,32 (0,20-0,49; p<0,001). O escore de PNI foi de 33,1±5,6 em pacientes com câncer. Detectou-se que em pacientes não oncológicos o escore foi 39,8±4,8 (p<0,001). Conclusão: Os escores HALP e PNI são testes de triagem de câncer fáceis e rápidos que podem prever metástases de câncer na etiologia de pacientes com derrame pericárdico.

Abstract Background: Cancer screening is absolutely necessary in patients with pericardial effusion, given that cancer is one of the most serious diseases in the etiology of pericardial effusion. In previous studies, it was stated that the systemic immune-inflammation index (SII); the prognostic nutrition index (PNI); and the hemoglobin, albumin, lymphocyte, platelet (HALP) score can produce scores related to cancer. Objectives: This study began considering that these scoring systems could predict cancer in the etiology of patients with pericardial effusion. Methods: This study produced a retrospective analysis of patients who underwent pericardiocentesis between 2006 and 2022. Pericardiocentesis was performed in a total of 283 patients with moderate-to-large pericardial effusion or pericardial tamponade within the specified period. HALP, PNI, and SII scores were calculated according to the peripheral venous blood taken before the pericardiocentesis procedure. The statistical significance level was set at p<0.05. Results: The HALP score proved to be 0.173 (0.125-0.175) in cancer patients and 0.32 (0.20-0.49) in non-cancer patients (p<0.001). The PNI score proved to be 33.1±5.6 in cancer patients and 39.8±4.8 in non-cancer patients (p<0.001). Conclusion: The HALP score and PNI proved to be easy and fast cancer screening tests that can predict cancer metastasis in the etiology of patients with pericardial effusion.

Objective:To screen the interacting protein of ubiquitin-conjugating enzyme E2S(UBE2S)and construct the hepatocellular carcinoma(HCC)based on UBE2S interacting protein prognosis model(UIPM),and to discuss the value of UIPM in assessing the prognosis of the HCC patients.Methods:Co-immunoprecipitation(Co-IP)was used to screen the protein complexes binding to Flag-UBE2S.After validation by sodium dodecyl sulphate-polyacrylamide gel electrophoresis(SDS-PAGE)and Western blotting methods;liquid chromatography-mass spectrometer(LC-MS)was used to identify the UBE2S interacting proteins;Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis were conducted on these proteins;the prognosis-related proteins from The Cancer Genome Atlas(TCGA)were cross-referenced with UBE2S interacting proteins by survival package of R software;the key proteins were extracted through LASSO regression analysis to build the UIPM;the prognostic model risk scoring formula was established.The HCC patients in TCGA were divided into high risk group and low risk group based on median value of the risk scores.The predictive accuracy of UIPM was evaluated by receiver operating characteristic curve(ROC),and the predictive accuracy was further validated by International Cancer Genome Consortium(ICGC)Database;univariate regression analysis and multivariate Cox regression analysis were used to detect whether the UIPM risk score was an independent prognostic factor for HCC.Furthermore,the nomogram model was built.Results:A total of 97 UBE2S interacting proteins were identified through Co-IP combined with LC-MS analysis.The GO functional enrichment analysis and KEGG signaling pathway enrichment analysis results showed that the interacting proteins were closely associated with cysteine-type endopeptidase activity,oxidative stress,and cell death.The TCGA revealed 5 163 HCC prognosis-related proteins;after intersecting with UBE2S interacting proteins,40 prognosis-related interacting proteins were found.Seven key proteins were determined through LASSO regression analysis,including UBE2S,heat shock protein family A member 8(HSPA8),heterogeneous nuclear ribonucleoprotein H1(HNRNPH1),chaperonin containing TCP1 subunit 3(CCT3),eukaryotic translation initiation factor 2 subunit 1(EIF2S1),receptor for activated C kinase 1(RACK1),and actin related protein 2/3 complex subunit 4(ARPC4),and the UIPM was constructed.There was significant difference in survival rate of the patients between high risk group and low risk group(P<0.05).The ROC curve analysis results showed the area under ROC curve(AUC)values of UIPM for predicting 1-year,2-year,and 3-year survival risk scores of the HCC patients were all greater than 0.7,indicating the model had high predictive accuracy.This was also confirmed by ICGC Database data.The univariate and multivariate Cox regression analysis results showed that the UIPM risk score was an independent prognostic risk factor for the HCC patients(P<0.05).The nomogram results showed good consistency between predicted survival rate and actual survival rate of the patient.Conclusion:A total of 97 interacting proteins that interact with UBE2S may promote the occurence and devolopment of HCC through oxidative stress and dysregulation of ferroptosis pathways.The UIPM risk score is an independent risk factor for the prognosis of HCC and can be used to predict the outcomes of the patients.UBE2S,HSPA8,HNRNPH1,CCT3,EIF2S1,RACK1,and ARPC4 could be regarded as the new biomarkers and therapeutic targets for HCC.

Analysis on severity of cerebral edema and prognostic influencing factors after mechanical thrombectomy in patients with acute ischemic stroke due to anterior circulation large vessel occlusion / 重庆医学

Objective To observe the severity of cerebral edema after mechanical thrombectomy in the patients with acute ischemic stroke caused by large vessel occlusion,and to statistically analyze the related fac-tors affecting the prognosis quality of the patients,so as to guide the patients to conduct scientific interven-tion.Methods Ninety-one patients with acute ischemic stroke due to anterior circulation large vessel occlusion treated with mechanical thrombectomy in this hospital from October 2021 to October 2022 served as the ana-lytic subjects.According to the severity of brain edema,they were divided into the group Ⅰ(mild),group Ⅱ(moderate),and group Ⅲ(severe);after 12-week treatment,the improved Rankin scale was used to evaluate the prognosis.The patients with good prognosis were included in the excellent group,and the patients with poor prognosis were included in the poor group.Single factor and multifactor logistic analysis was used to ana-lyze the influencing factors and prognostic related factors of different degrees of brain edema.Results The univariate analysis showed that the percentage of patients with NIHSS score at admission ≥15,time from on-set to thrombolysis ≥6 h,history of hypertension,successful vascular recanalization and good collateral circu-lation were significantly different among the groups Ⅰ,Ⅱ and Ⅲ(P＜0.05);the multivariate logistic regres-sion analysis results showed that the NIHSS score at admission ≥15,time from onset to thrombolysis ≥6 h,and hypertension history were the risk factors leading to severe cerebral edema,while successful recanalization of blood vessels was a protective factor for cerebral edema(P＜0.05).The univariate analysis showed that in the good prognosis group the percentage of patients had good circulation of lateral branches,successful reca-nalization of blood vessels,severe cerebral edema,hypertension,time from onset to thrombolysis ≥6 h,and NIHSS score ≥15 at admission were significantly different from those in the poor prognosis group(P＜0.05).The multivariate logistic regression analysis results showed that severe cerebral edema,time from onset to thrombolysis ≥6 h and NIHSS score ≥15 at admission were the risk factors for poor prognosis,while good collateral circulation and successful recanalization of blood vessels were the positive factors for good prognosis(P＜0.05).Conclusion Mechanical thrombectomy patients with hypertension and time from onset to throm-bolysis ≥6 h and NIHSS score at admission ≥15 have more severe brain edema after treatment;severe brain edema,time from onset to thrombolysis ≥6 h,NIHSS score at admission ≥15 were the adverse factors affect-ing the prognosis of the patients with mechanical thrombectomy.

Clinical characteristics and prognostic factors of young patients with sporadic rectal cancer liver metastasis / 解放军医学杂志

Objective To identify the clinical characteristics and prognostic factors of young patients with sporadic rectal cancer liver metastasis(RCLM).Methods The clinical data of young RCLM patients at 45 years or under(n=40,as younger patient group)in Peking University First Hospital from January 2016 to January 2021 were reviewed,meanwhile,elder RCLM patient group were comprised of 82 patients older than 45-year-old in a 1:2 ratio.Proportions of categorical variables were compared between young patients and old patients.The clinicopathologic parameters were analyzed with univariate and multivariate Cox regression models and Kaplan-Meier method for demonstrating survival differences between the maximum diameter of liver metastasis and local therapy.Results One hundred and twenty-two RCLM patients were identified,the 1-,3-and 5-year survival rates of young patient group were 97.5%,47.5%,15.0%,those of elder patient group were 84.1%,26.8%,9.8%,respectively.The differences in BMI(P=0.008),primary tumor with obstruction and bleeding(P=0.006),synchronous rectal cancer liver metastases(P=0.005),the maximum diameter of liver metastasis>3 cm(P=0.019)were statistically significant between the two groups.And univariate and multivariate analyses showed that age(P=0.003),N stage(P=0.007),local therapy for liver metastases(P=0.047)and the maximum diameter of liver metastasis(P=0.030)were independent risk factors for influencing the prognosis of RCLM patients;curative resection or not of primary tumor(P=0.035)and the maximum diameter of liver metastasis(P=0.041)were independent risk factors for influencing the prognosis of young RCLM patients.Kaplan-Maier curve demonstrated survival differences between the maximum diameter of liver metastasis and local therapy for liver metastasis in RCLM patients(log-rank P=0.000).Conclusions Although with later staging of initial tumor station,young RCLM patients may obtain better survival benefit compared with old patients.Higher degree of lymph node metastasis,local therapy for liver metastases and the maximum diameter of liver metastasis>3 cm indicates poor prognosis in RCLM patients,and without curative resection of primary tumor and maximum diameter of liver metastasis are also considered as the independent poor prognostic factors of young RCLM patients.Local therapy for liver metastases appears to play an important role in the treatment strategy of RCLM patients.

Expression of bone morphogenetic protein 9 in patients with sepsis-associated acute respiratory distress syndrome and its role in early recognition and prognosis prediction of disease / 中华急诊医学杂志

Objective:To observe the expression level of bone morphogenetic protein 9 (bone morphogenetic protein 9,BMP9) in patients with sepsis-associated acute respiratory distress syndrome (acute respiratory distress syndrome,ARDS), and to explore the role of BMP9 in early recognition and prognosis prediction of sepsis-associated ARDS.Methods:From May 2022 to May 2023, total of 56 patients with sepsis-associated ARDS in Shanxi Bethune Hospital were selected as the ARDS group, 49 patients with cardiogenic pulmonary edema as the case control group, and 46 adults who underwent physical examination in the physical examination center of our hospital as the healthy control group.The patients in the ARDS group were followed up for 28 days and divided into survival group ( n = 26) and death group ( n = 30). The expression level of serum BMP9 and its correlation with clinical indicators in each group were analyzed and compared. The risk factors of sepsis-associated ARDS were analyzed by Logistic regression, and the diagnostic efficacy and prognostic value of related indicators were analyzed. Results:The serum level of BMP9 in sepsis-associated ARDS group [1401.14 (856.59,1982.86) ]pg/mL was significantly higher than that in case control group (438.26±128.52) pg/mL and healthy control group (398.96±96.55)pg/mL, the differences were statistically significant ( P<0.01). In addition, BMP9 expression significantly correlated with procalcitonin, lymphocyte count and SOFA score ( P < 0.05, P < 0.01, respectively). Multivariate Logistic regression analysis showed that BMP9 was a high risk factor for the development of sepsis-associated ARDS ( P<0.01). The area under the ROC curve (area under the ROC curve,AUC) of BMP9 to predict the occurrence of sepsis-associated ARDS was 0.930. The specificity was 100.0% and the sensitivity was 80.4%, which was significantly higher than the specificity (89.8%) and sensitivity (67.9%) of the oxygenation index. Follow-up and comparison of BMP9 levels in patients with different prognosis of sepsis-associated ARDS showed that the expression level of BMP9 in the death group was higher than that in the survival group, and the difference was statistically significant ( P < 0.05). The ROC curve of BMP9 in predicting the prognosis of patients with sepsis-associated ARDS. The area under the ROC curve was 0.699, the sensitivity was 43.3%, and the specificity was 100.0%. Conclusions:The expression of BMP9 in sepsis-associated ARDS patients significantly increased, and its high expression was significantly correlated with inflammatory markers such as procalcitonin, lymphocyte count and SOFA score. BMP9 is an independent risk factor in patients with sepsis-associated ARDS, and it is promising as a new biomarker for early identification of sepsis-associated ARDS. However, it do not show a good predictive effect on the prognosis of the disease.

Objective·To analyze the clinicopathologic characteristics,gene mutation profile,and prognostic factors of thyroid diffuse large B-cell lymphoma(DLBCL).Methods·From November 2003 to December 2021,a total of 66 patients with thyroid DLBCL[23 cases(34.8%)with primary thyroid DLBCL,and 43 cases(65.2%)with secondary thyroid DLBCL]admitted to Ruijin Hospital,Shanghai Jiao Tong University School of Medicine were retrospectively analyzed for their clinicopathological data,survival and prognostic factors.Gene mutation profiles were evaluated by targeted sequencing(55 lymphoma-related genes)in 40 patients.Results·Compared to primary thyroid DLBCL,secondary thyroid DLBCL had advanced ratio of Ann Arbor stage Ⅲ?Ⅳ(P=0.000),elevated serum lactate dehydrogenase(LDH)(P=0.043),number of affected extranodal involvement≥2(P=0.000),non-germinal center B cell(non-GCB)(P=0.030),BCL-2/MYC double expression(DE)(P=0.026),and international prognostic index(IPI)3?5-scores(P=0.000).The proportion of patients who underwent thyroid surgery(P=0.012)was lower than that of patients with primary thyroid DLBCL.The complete remission(CR)rate in primary thyroid DLBCL patients was higher than that in secondary thyroid DLBCL patients(P=0.039).Fifty-five patients(83%)received rituximab combined with cyclophosphamide,doxorubicin,vincristine,and prednisone(R-CHOP)-based first-line regimen.The estimated 5-year progression free survival(PFS)rate of primary thyroid DLBCL patients was 95.0%,higher than the 49.7%of the secondary patients(P=0.010).Univariate analysis showed that Ann Arbor Ⅲ?Ⅳ(HR=4.411,95%CI 1.373?14.170),elevated LDH(HR=5.500,95%CI 1.519?19.911),non-GCB(HR= 5.291,95%CI 1.667?16.788),and DE(HR=6.178,95%CI 1.813?21.058)were adverse prognostic factors of PFS in patients with thyroid DLBCL.Ann Arbor Ⅲ?Ⅳ(HR=7.088,95%CI 0.827?60.717),elevated LDH(HR=6.982,95%CI 0.809?60.266),and DE(HR=18.079,95%CI 1.837?177.923)were adverse prognostic factors of overall survival(OS).Multivariate analysis showed that Ann Arbor Ⅲ?Ⅳ(HR=4.693,95%CI 1.218?18.081)and elevated LDH(HR=5.058,95%CI 1.166?21.941)were independent adverse prognostic factors of PFS in patients with thyroid DLBCL.Targeted sequencing data showed mutation frequency>20%in TET2(n=14,35%),KMT2D(n=13,32%),TP53(n=11,28%),GNA13(n=10,25%),KMT2C(n=9,22%),and TP53 were adverse prognostic factors of PFS in patients with thyroid DLBCL(P=0.000).Conclusion·Patients with primary thyroid DLBCL have better PFS and OS than those with secondary thyroid DLBCL.Ann Arbor Ⅲ?Ⅳ,elevated LDH,non-GCB,and DE(MYC and BCL2)are adverse prognostic factors in thyroid DLBCL.TET2,KMT2D,TP53,GNA13,and KMT2C are commonly highly mutated genes in thyroid DLBCL,and the prognosis of patients with TP53 mutations is poor.

Construction and Evaluation of the Disulfidptosis-Related Genes(DRGs)Prognostic Risk Model for Hepatocellular Carcinoma Based on TCGA Database / 现代检验医学杂志

Objective To construct and evaluate a disulfidptosis-related genes(DRGs)prognostic risk model for hepatocellular carcinoma(HCC)based on the cancer genome atlas(TCGA)database.Methods The expression of 15 DRGs in 371 HCC samples and 50 adjacent cancer samples in the TCGA database was analyzed using bioinformatics methods,and then gene ontology(GO)functional annotation,Kyoto encyclopedia of genes and genomes(KEGG)enrichment analysis and Kaplan-Meier(KM)survival analysis were performed.Statistical significant DRGs were screened through univariate COX regression analysis,and key DRGs were selected through LASSO regression analysis and multivariate COX regression analysis to construct a prognostic risk model.HCC patients were divided into high-risk and low-risk groups based on risk scores,and the KM survival curves and time-dependent receiver operator characteristic(ROC)curves were created to validate and evaluate prognostic risk models.Results Compared with the adjacent cancer samples,FLNA,MYH9,TLN1,ACTB,MYL6,CAPZB,DSTN,ACTN4,SLC7A11,INF2,CD2AP,PDLIM1,and FLNB were all upregulated in the 15 DRGs of HCC samples,and the differences were significant(t=1 793～6 310,all P<0.001).According to GO functional annotation and KEGG enrichment analysis,DRGs were closely related to biological processes or pathways related to actin cytoskeleton and cell adhesion.The results of KM survival analysis showed that the survival rate of the high expression group of SLC7A11,INF2,CD2AP,MYL6,and ACTB were lower than that of the low expression group[HR=1.46(1.03～2.07)～1.93(1.36～2.75),all P<0.05].Univariate COX regression analysis,LASSO analysis,and multivariate COX regression analysis were used to construct a prognostic risk model,with risk score=(0.247×SLC7A11)+(0.289×INF2)+(0.076×CD2AP)+(0.06×MYL6).The risk score of the sample in this model was calculated,and the higher the risk score,the more HCC patients with poor prognosis.KM survival analysis showed that the overall survival rate of the high-risk group was lower than that of the low-risk group.The AUC values for 1,3,and 5 years were 0.709,0.661,and 0.648,respectively.Multivariate COX regression analysis showed that SLC7A11[HR=1.832(1.274～2.636),P=0.001]was an independent prognostic risk factor.Conclusion The prognostic risk model was constructed by four DRGs,which has a certain role in predicting the prognosis of HCC patients.
