Adverse Prognosis In Patients Research Articles

Application of preoperative NLR-based prognostic model in predicting prognosis of intrahepatic cholangiocarcinoma following radical surgery

PurposeTo investigate the application value of the neutrophil to lymphocyte count ratio (NLR) in the prognostic analysis of intrahepatic cholangiocarcinoma (ICC) after radical resection, and to offer guidance for the individualized perioperative diagnosis and treatment of ICC.MethodsThe clinical data of 360 patients diagnosed with ICC following radical surgery were retrospectively analyzed. The cut-off value of NLR was calculated using the minimum p-value method, and then divided into High-NLR (H-NLR) group and Low-NLR (L-NLR) group according to the NLR cut-off value. The prognostic value of NLR in ICC was analyzed. Subsequently, the patients were divided into the hepatolithiasis-related intrahepatic cholangiocarcinoma (HICC) group and the non-hepatolithiasis-related intrahepatic cholangiocarcinoma (NHICC) group based on whether they combined with hepatolithiasis. Multiple regression models were constructed based on NLR and clinicopathological indicators to verify the application value of prognostic models in the survival and recurrence of ICC patients after radical surgery.ResultsThe cut-off value of NLR was 2.36, and the survival analysis disclosed that overall ICC patients with NLR ≥ 2.36 manifested a poor 5-year survival rate and a higher tumor recurrence rate (p < 0.001). In the HICC group, patients with H-NLR presented a poor 5-year survival rate and a higher tumor recurrence rate compared with L-NLR (p < 0.001). The NLR-based survival/recurrence prediction models in the HICC group demonstrated excellent predictive capacity (H-L test: 0.359/0.680, AUC: 0.764/0.791). In the NHICC group, patients with H-NLR exhibited a poor 5-year survival rate compared with L-NLR (p < 0.001), yet there was no significant difference in tumor recurrence between the two groups (p = 0.071). The NLR-based survival prediction model in the NHICC group demonstrated acceptable predictive ability (H-L test: 0.268, AUC: 0.729), while the NLR-based recurrence prediction model did not show an effective predictive ability (H-L test: 0.01, AUC: 0.649).ConclusionNLR is an independent risk factor influencing postoperative survival and recurrence in ICC patients, particularly in HICC patients. Preoperative NLR ≥ 2.36 suggests that patients might have a poor prognosis. The survival and recurrence prediction model constructed based on NLR and other clinical indicators demonstrates good prediction accuracy and can effectively predict the risk of postoperative adverse prognosis in patients with HICC. This study offers a novel idea for the clinical treatment of HICC patients.

Prior fecal immunochemical test positivity is associated with adverse prognosis in patients with acute ST-segment elevation myocardial infarction

Abstract Backgrounds While fecal immunochemical testing (FIT) is commonly used for disease screening, its significance in other conditions, particularly in patients with ST-segment elevation myocardial infarction (STEMI), is not extensively researched. Purpose This study aimed to investigate the impact of prior positive FIT results on the clinical prognosis of patients with STEMI. Methods The data for this study were derived from the Health and Medical Big Data Superplatform, comprising a retrospective cohort of patients discharged from 72 hospitals from 2010 to 2023. A total of 76,157 patients with acute STEMI patients were enrolled. Positive FIT was defined as "+-" or higher on the fecal occult blood test. Propensity score matching (PSM) was employed to balance differences between the two groups. Kaplan-Meier analysis with log-rank tests compared endpoint risks between groups, and a multivariable Cox regression model adjusted for potential confounders. The primary endpoint was Net Adverse Clinical Event (NACE), including cardiac death, recurrent myocardial infarction, revascularization, stroke, cerebral hemorrhage, and gastrointestinal bleeding. Results After 1:3 PSM,2,148acute STEMI patients were included, with 537 having prior positive FIT and 1,611 without. Patients with prior positive FIT were more likely to have comorbidities such as hyperlipidemia, prior malignancy, post-coronary artery bypass grafting, renal insufficiency, and prior cerebral hemorrhage. The prior positive FIT group had a higher proportion of prior clopidogrel and indobufen usage, while aspirin use during follow-up was lower. Kaplan-Meier analysis demonstrated a significantly higher risk of NACE in acute STEMI patients with prior positive FIT (before PSM: log-rank P = 0.001, after PSM: log-rank P = 0.005, Figure 1）, as well as increased rates of Major Adverse Cardiac and Cerebral Events (MACCE), all-cause death, and gastrointestinal bleeding (log-rank P < 0.05 for all). Multivariate Cox-proportional hazard analysis adjusted for age, sex, percutaneous coronary intervention during hospitalization, diabetes, hypertension, ischemic stroke, atrial fibrillation, medication during hospitalization, and follow-up showed similar results (Figure 2). Conclusions This study reveals a significant association between prior positive FIT and higher rates of NACE, MACCE, all-cause death, and gastrointestinal bleeding in STEMI patients within 1 year. A history of positive FIT results could serve as a prognostic indicator in this specific patient population.

Prevalance and impact of concomitant atrial fibrillation in patients undergoing percutaneous coronary intervention for acute myocardial infarction

Abstract Introduction Atrial fibrillation (AF) is a common cardiac arrhythmia associated with coronary artery disease (CAD) and myocardial infarction (MI). The prevalence of AF in patients following acute MI varies, with conflicting evidence on its impact on outcomes. Concomitant atrial fibrillation is associated with an adverse prognosis in patients with acute myocardial infarction (MI). However, it remains unclear whether this is due to a causal effect of AF, or whether AF acts as a surrogate marker for comorbidities in this population Also, there are limited data on whether coronary artery disease distribution impacts the risk of developing AF. Purpose This large cohort study aims to determine the prevalence of AF in acute MI patients treated with PCI, assess its independent prognostic value for MACCE, investigate the association of AF with CAD distribution patterns, and provide insights into the long-term outcomes of AF in this patient population. Methods A cohort of 1000 consecutive MI patients treated with PCI was retrospectively analyzed. Data on demographics, medical history, presentation, treatment, and outcomes was collected. Propensity score matching was used to adjust for baseline differences between AF and non-AF groups. CAD distribution, major adverse events, and MACCE were assessed using statistical analyses. Results Amongst the studied population, 6.5% people had AF (65/1000) and it was noted that those with AF had a worse outcome. However, on statistical analyses (both on multivariable cox and propensity matching) accounting for risk factors, outcomes were not significantly different between those with and without AF. Hence, this negated key baseline differences between AF and non-AF groups, with no significant differences in demographics or presentation. Patients with AF had a higher prevalence of severe CAD in the left main stem (LMS) and left circumflex artery (LCx). The association of AF with MACCE was not significant in the matched groups. Long-term follow-up revealed similar rates of MACCE between AF and non-AF groups. Discussion AF in acute MI patients undergoing PCI is associated with a higher prevalence of severe CAD in the LMS and LCx. AF appears to be a surrogate marker of other risk factors, rather than an independent risk factor for MACCE. The study highlights the need for tailored aggressive treatment for risk factor modification in AF patients with MI. Conclusions AF is associated with an increased risk of MACCE in acute MI patients undergoing PCI. However, this association is primarily driven by the burden of comorbidities associated with AF, emphasizing the importance of tailored treatment strategies for AF patients. Prospective studies with routine ambulatory monitoring are recommended to validate these findings and guide future practice.

Neutrophil-to-lymphocyte ratio can predict the clinical prognosis of patients with primary adosteronism

Abstract Background Excess aldosterone-mediated inflammatory response is thought to be a factor in the high risk of cardiovascular events in patients with primary aldosteronism (PA). Leucocyte related inflammatory parameters, especially NLR, were significantly independent of aldosterone (PAC) in PA patients. However, the impact of NLR on the long-term prognosis of PA patients is unclear. Objective To explore the predictive value of neutrophil-to-lymphocyte ratio (NLR) on the long-term prognosis of patients with primary aldosteronism (PA). Methods The data for this study were derived from the Tianjin Health and Medical Big Data Super platform, comprising a retrospective cohort of patients discharged from 72 hospitals in our city from 2010 to 2023. According to the inclusion and exclusion criteria, 570 patients were ultimately included in the statistical analysis. Each patient had laboratory measurements, including blood cell counts, taken after admission and before interventional treatment. The primary endpoint was major cardiovascular events (MACEs), defined as cardiovascular death, nonfatal myocardial infarction (MI), and nonfatal stroke. Results During a mean follow-up period of 5 years, 125（21.9%）MACEs were recorded. ROC curve analysis displayed that the best cut-off value of NLR for predicting MACEs was 4.87. The MACEs of the high NLR group at 1 year, 3 years, and 5 years were higher than those of the low NLR group（25.0% vs 9.4%，40.3% vs17.1% 和 40.3% vs 19.3%；P＜0.05).Kaplan-Meier survival curve analysis showed that the survival rate of the low NLR group was higher than that of the high NLR group (P<0.001). The results of multivariate Cox proportional hazards regression analysis showed that NLR was an independent risk factor affecting the prognosis of PA patients, and the difference was statistically significant (P<0.05). Conclusions Elevated NLR is associated with adverse prognosis in patients with PA. NLR can serve as a simple and practical indicator to evaluate the long-term prognosis of PA patients. These findings warrant external validation, preferably in a prospective design.

The dynamic increment of epicardial adipose tissue is associated with reverse remodeling after guideline-directed medical treatment in dilated cardiomyopathy patients

Abstract Background/Introduction Epicardial adipose tissue (EAT) accumulation is associated with adverse prognosis in patients with HFpEF and a better prognosis in HFrEF patients. Whether EAT is playing a protective role in dilated cardiomyopathy (DCM) patients have been described sparingly. Purpose Aim to explore whether the epicardial fat would change along with the dynamic changes in cardiac function and volumes after receiving guideline-directed medical therapy (GDMT) in patients with DCM. Methods We prospectively enrolled 232 DCM patients who underwent complete baseline and follow-up Cardiac magnetic resonance (CMR) examinations. The measurement of the epicardial fat composition includes epicardial fat thickness, paracardial fat thickness, and paracardial fat volume, while the measurement of body fat composition includes subcutaneous and visceral abdominal fat, while We used univariable and multivariable logistic regression to evaluate the association between different body and cardiac fat depots with the changes in bi-ventricular structure (delta indexed EDV) and function (delta EF). Results The study included 232 patients (mean age 46.1±14.1 years, 157 (67.7%) males). After GDMT, we found that the visceral fat thickness and EAT (thickness and volume) tend to significantly increase. The increase in the (left ventricular reverse remodeling) LVRR group was significantly higher compared with the non-LVRR group. Independently with the changes of BMI and body fat depots, the increment of EAT was associated with the improvement in bi-ventricular function and volumes (significantly positively correlated with the improvement of LVEF (r = 0.499, p < 0.001), and RVEF (r = 0.482, p < 0.001), negatively correlated with delta LVEDVi (r = -0.407, p < 0.001), delta RVEDVi (r = -0.305, p < 0.001)). Conclusions After GDMT, the increment of EAT was positively correlated with the improvement of bi-ventricular structure and function, independent of the changes in BMI and body fat depots.Graphic Abstract

Diagnostic value of exosomal N‐glycan profiles for microvascular invasion in hepatocellular carcinoma

AbstractBackgroundMicrovascular invasion (MVI) was a critical high‐risk factor for postoperative recurrence and adverse prognosis in patients with hepatocellular carcinoma (HCC), and there were no reliable non‐invasive pre‐operative diagnostic markers. The exosomal N‐glycan profile was closely related to the invasion and immune escape of HCC. Therefore, this article investigated the expression of N‐glycan profiles in serum exosomes of patients with HCC and its clinical significance for MVI.MethodsSerum samples from 210 patients with HCC were collected and randomly divided into modeling and validation cohorts. The abundances of N‐glycans in serum exosomes with different MVI grades were determined. A diagnostic model for MVI in HCC based on N‐glycosylation was constructed and the diagnostic value was analyzed.ResultsIn the modeling cohort, comparing groups M0 with M2, the area under the receiver operating characteristic (AUC) of the diagnostic model namely SUM (AUCSUM) was 0.861, the sensitivity of SUM was 92.68%, and the specificity of SUM was 79.41%, all of which were higher than the seven individual indexes (containing Peak 1, Peak 6, Peak 9, Peak 10, Peak 12, AFP, and PIVKA‐II). In the comparison between the M1 and M2 groups, the AUCSUM was 0.749, the sensitivity of SUM was 79.07%, and the specificity of SUM was 76.60%, all of which were higher than the seven individual indexes. When comparing the M0 and M1 groups, the AUCSUM was 0.712, the sensitivity of SUM was 88.57%, and the specificity of SUM was 65.00%. The AUCSUM and sensitivity of SUM were higher than the seven individual indexes and the specificity of SUM was slightly lower than that of AFP (68.18%) but higher than other individual indexes. The results of the validation cohort were similar to those of the modeling cohort.ConclusionThe SUM model of serum exosomes can serve as an auxiliary diagnostic index for MVI staging in patients with HCC.

High levels of blood lipid and glucose predict adverse prognosis in patients with aneurysmal subarachnoid hemorrhage

ObjectiveWe conducted a retrospective study on the prognostic factors of aneurysmal subarachnoid hemorrhage (aSAH) patients in the author's Hospital from January 2019 to May 2023. To discuss the association of the blood lipid and glucose levels of patients with the prognosis of aSAH, and verify that high blood lipid and glucose levels are important factors affecting adverse prognosis. MethodsAll patients with aSAH were collected as the case group, which was divided into two groups according to the modified Rankin Scores (mRS), the good prognosis group (Group A, mRS ＜ 3) and the adverse prognosis group (Group B,mRS ≥3). The clinical data of age, gender, accompanied chronic diseases (hypertension, diabetes), smoking, drinking, Glasgow Coma Scale (GCS), Hunt-Hess (H-H) grade, Modified Fisher grade, total cholesterol (TC) , triglyceride (TG) , high-density cholesterol lipoprotein (HDL-C) , low-density cholesterol lipoprotein (LDL-C) , blood glucose (BG) , responsible aneurysm diameter and location were recorded too. Correlations between blood lipid and glucose levels and Modified Fisher grade were assessed by the Spearman correlation analysis. The receiver operating characteristic (ROC) curve was utilized to evaluate the diagnostic efficacy. The effect of blood lipid and glucose levels on adverse prognosis was analyzed by Logistic regression models. ResultA total of 259 patients with aSAH were enrolled. The average age of all patients is (56.54 ± 10.52) years, including 96 males and 163 females. They were divided into Group A (n = 146) and Group B (n = 113). Univariate analysis results show that age, the levels of TC, TG, LDL-C, and BG were higher in Group B (P < 0.05). Besides, Group B had more severe GCS, H-H grade, and Modified Fisher grade than Group A, and a higher proportion of intracranial aneurysms with larger diameter (P < 0.05). Correlation analysis showed that TC, TG, LDL-C, and BG levels were positively correlated with Modified Fisher grade (P < 0.05) and H-H grade (P < 0.05). Multivariate logistic regression model analysis showed that high level of Modified Fisher grade (OR = 0.079, 95%CI: 0.027–0.230) , high level of H-H grade (OR = 0.204, 95%CI: 0.067–0.622) , TC (OR = 10.711, 95%CI: 2.457–46.700) , LDL-C (OR = 0.178, 95%CI: 0.039–0.823) and BG (OR = 1.273, 95%CI: 1.012–1.602) increased the risk of adverse prognosis. The AUC of “H-H grade”, “Modified Fisher grade”, “TC level”, “LDL-C level” and “BG level” was 0.822, 0.885, 0.860, 0.772, and 0.721, respectively, in the ROC curve. ConclusionModified Fisher grade, H-H grade, TC, LDL-C, and BG levels at admission were independent predictors of adverse prognosis of aSAH. Besides, TC, LDL-C, and BG levels were positively correlated with Modified Fisher grade and Hunt-Hess grade. What's more, high levels of TC, LDL-C, and BG combined with Modified Fisher grade and H-H grade can identify high-risk groups with adverse prognoses in aSAH patients.

Association between the C-reactive protein to albumin ratio and poor clinical outcome in patients with spontaneous intracerebral hemorrhage

BackgroundThe C-reactive protein-to-albumin ratio (CAR) is a novel prognostic biomarker of systemic inflammation and nutritional status. The association between CAR and the long-term outcome of spontaneous intracerebral hemorrhage (ICH) remains unclear. MethodsFrom January 2014 to September 2016, 497 patients with spontaneous ICH were enrolled in our study from 13 hospitals in Beijing. According to the CAR quartiles, patients were classified into four groups (Q1-Q4). Logistic regression was applied to analyze the relationship between different CAR levels and main outcome (90-day and 1-year mRS 4-6). Restricted cubic splines and receiver operating characteristic (ROC) curves of CAR for poor clinical outcomes were assessed. ResultsIn the multivariate logistic regression model, compared with the lowest quartile of CAR, the adjusted odds ratios of the Q2, Q3, and Q4 group for 90-day mRS score of 4-6 were 3.64 (1.61–8.23), 3.83 (1.67–8.77), and 8.91 (3.85–20.64). In terms of 1-year mRS score of 4-6, compared with the lowest quartile of CAR, the adjusted odds ratios of the Q3 and Q4 group were 3.31 (1.33–8.22) and 6.87 (2.81–16.78). ConclusionsA high CAR level was associated with a high risk of long-term adverse prognosis in patients with ICH, and the risk of ICH poor outcome increased steadily with CAR rising in a certain range, and maintained in a high level thereafter.

Cystathionine-β-synthase expression correlates with tumour progression and adverse prognosis in patients with colon cancer.

To investigate the levels of cystathionine-β-synthase (CBS) in colon cancer tissues compared with adjacent control tissues; and to examine the relationship between CBS level and clinical characteristics and prognosis. This retrospective study enrolled patients with primary colon cancer. Paraffin-embedded specimens were used to create pathological tissue microarrays. Immunohistochemistry was performed on the microarray to detect the levels of CBS in colon cancer tissues and normal adjacent tissues. Analyses were undertaken to examine the relationship between the level of CBS and clinical characteristics and prognosis. A total of 216 patients (107 males and 109 females) were included in the study. The level of CBS in cancer tissues was found to be significantly increased compared with normal adjacent control tissues. There were significant differences in tumour location, tumour-node-metastasis stage and survival rate between the CBS-negative and CBS-positive groups. Positive CBS immunostaining was associated with decreased survival in colon cancer patients. The results of multivariate Cox regression analysis revealed that tumour location and positive CBS immunostaining were independent prognostic factors for survival. Positive CBS immunostaining was closely associated with colon cancer and high levels of CBS might accelerate tumour development and affect patient prognosis in colon cancer.

Emerging opportunities to target inflammation: myocardial infarction and type 2 diabetes.

After myocardial infarction (MI), patients with type 2 diabetes have an increased rate of adverse outcomes, compared to patients without. Diabetes confers a 1.5-2-fold increase in early mortality and, importantly, this discrepancy has been consistent over recent decades, despite advances in treatment and overall survival. Certain assumptions have emerged to explain this increased risk, such as differences in infarct size or coronary artery disease severity. Here, we re-evaluate that evidence and show how contemporary analyses using state-of-the-art characterization tools suggest that the received wisdom tells an incomplete story. Simultaneously, epidemiological and mechanistic biological data suggest additional factors relating to processes of diabetes-related inflammation might play a prominent role. Inflammatory processes after MI mediate injury and repair and are thus a potential therapeutic target. Recent studies have shown how diabetes affects immune cell numbers and drives changes in the bone marrow, leading to pro-inflammatory gene expression and functional suppression of healing and repair. Here, we review and re-evaluate the evidence around adverse prognosis in patients with diabetes after MI, with emphasis on how targeting processes of inflammation presents unexplored, yet valuable opportunities to improve cardiovascular outcomes in this vulnerable patient group.

The prognostic value of lymph node response to neoadjuvant therapy among breast cancer subtypes

Objectives. The aim of this study was to assess the prognostic value of persistent node involvement after neoadjuvant chemotherapy among breast cancer subtypes. Materials and methods. A total of 258 patients with T1-T4 and N0-N3 breast cancer treated by neoadjuvant chemotherapy followed by tumor excision and axillary lymph-node dissection between January 2015 and December 2019 were selected from the Coltea Clinical Hospital database and retrospectively evaluated. Association between nodal involvement (ypN) binned into four classes (0, 1-3, 4-9 and &gt;10), relapse free-survival and overall survival among the whole population and according to breast cancer subtypes was analyzed using Statistical Package for Social Science Version 29.0.2.0. Outcomes. After a median follow-up of 20.7 months (range 1-97 months) post neoadjuvant chemotherapy nodal involvement was significantly associated with disease free survival in the whole population (X2(3)= 23.161, p &lt;.001) and between breast cancer subgroups (X2(3) = 27.871, p= &lt;.001). After univariate cox regression analyses by breast cancer subtypes nodal involvement was statistically significant only in the Luminal B(HER-) (X2(3)=14.867, p=.002) and triple-negative breast cancer (X2(3)= 9.867, p=.020). In Luminal B(HER2-) breast cancers all nodal involvement subgroups were associated with impaired relapse free survival compared to ypN0 tumors (1-3 nodes, HR= 4.871, 95%CI [1.32-17.94], p=.017; 4-9 nodes, HR=5.126, 95%CI [1.341-19.59], p=.017; &gt;10 nodes, HR=8.744, 95%CI [2.379-32.13], p=.001). In triple negative breast cancers, relapse-free survival was associated with an adverse prognosis in patients with more than 10 nodes involved when compared with ypN0 (HR=16.57, 95%CI [3.25-84.30], p=&lt;.001). There was no statistically significant association in the univariate cox regression analyze between post neoadjuvant chemotherapy nodal involvement and overall survival neither in the whole population (X2(3)=.992, p=.803) nor among breast subtypes (X2(3)=1.191, p= .779). Kaplan Meier analyze of RFS adjusted for BC subtype showed a statistically significant relapse rate in all groups (1-3 (p=.035), 4-9(p=&lt;.001), &gt;10 (p=&lt;.001)) compared with ypN0 group. Kaplan Meier overall survival analyze showed no statistical difference in survival among node groups. Conclusions. Post neoadjuvant chemotherapy lymph node status in breast cancer subtypes represents an important prognostic factor of relapse-free survival and the prognostic value of residual axillary disease should be interpreted according to breast cancer subtype.

Unveiling the role of UPF3B in hepatocellular carcinoma: Potential therapeutic target.

RNA-binding proteins can regulate nucleotide metabolism and gene expression. UPF3B regulator of nonsense mediated mRNA decay (UPF3B) exhibits dysfunction in cancers. However, its role in the progression of hepatocellular carcinoma (HCC) is still insufficiently understood. Here, we found that UPF3B was markedly upregulated in HCC samples and associated with adverse prognosis in patients. UPF3B dramatically promoted HCC growth both invivo and invitro. Mechanistically, UPF3B was found to bind to PPP2R2C, a regulatory subunit of PP2A, boosting its mRNA degradation and activating the PI3K/AKT/mTOR pathway. E2F transcription factor 6 (E2F6) directly binds to the UPF3B promoter to facilitate its transcription. Together, the E2F6/UPF3B/PPP2R2C axis promotes HCC growth through the PI3K/AKT/mTOR pathway. Hence, it could be a promising therapeutic target for treating HCC.

Establishment and validation of a bad outcomes prediction model based on EEG and clinical parameters in prolonged disorder of consciousness.

This study aimed to explore the electroencephalogram (EEG) indicators and clinical factors that may lead to poor prognosis in patients with prolonged disorder of consciousness (pDOC), and establish and verify a clinical predictive model based on these factors. This study included 134 patients suffering from prolonged disorder of consciousness enrolled in our department of neurosurgery. We collected the data of sex, age, etiology, coma recovery scales (CRS-R) score, complications, blood routine, liver function, coagulation and other laboratory tests, resting EEG data and follow-up after discharge. These patients were divided into two groups: training set (n = 107) and verification set (n = 27). These patients were divided into a training set of 107 and a validation set of 27 for this study. Univariate and multivariate regression analysis were used to determine the factors affecting the poor prognosis of pDOC and to establish nomogram model. We use the receiver operating characteristic (ROC) and calibration curves to quantitatively test the effectiveness of the training set and the verification set. In order to further verify the clinical practical value of the model, we use decision curve analysis (DCA) to evaluate the model. The results from univariate and multivariate logistic regression analyses suggested that an increased frequency of occurrence microstate A, reduced CRS-R scores at the time of admission, the presence of episodes associated with paroxysmal sympathetic hyperactivity (PSH), and decreased fibrinogen levels all function as independent prognostic factors. These factors were used to construct the nomogram. The training and verification sets had areas under the curve of 0.854 and 0.920, respectively. Calibration curves and DCA demonstrated good model performance and significant clinical benefits in both sets. This study is based on the use of clinically available and low-cost clinical indicators combined with EEG to construct a highly applicable and accurate model for predicting the adverse prognosis of patients with prolonged disorder of consciousness. It provides an objective and reliable tool for clinicians to evaluate the prognosis of prolonged disorder of consciousness, and helps clinicians to provide personalized clinical care and decision-making for patients with prolonged disorder of consciousness and their families.

Analysis of risk factors for postoperative recurrence of stage I colorectal cancer: a retrospective analysis of a large population.

Colorectal cancer (CRC) is the third most common cancer worldwide. Patients diagnosed with stage I CRC typically do not require postoperative adjuvant treatment. However, postoperative recurrence is present in at least 40% of patients with CRC and often occurs in those with stage I disease. This study aimed to elucidate the current status of recurrence and clinicopathological characteristics in patients with stage I CRC. Data of indicated patients were obtained from 18 registries in Surveillance, Epidemiology, and End Results (SEER). The multivariable Fine-Gray regression model was used to identify the mortality risk of patients. Disparities in survival were analyzed using Kaplan-Meier curves. Logistic regression was employed to identify factors associated with recurrent risk overestimation. Our study indicated a recurrence rate of 15.04% (1,874/12,452) in stage I CRC cases. Notably, we identified race, age, T stage, and carcinoembryonic antigen (CEA) levels as independent risk factors for tumor recurrence, substantially impacting prognosis. Furthermore, gender, race (Black), age (>65 years), elevated CEA levels, and refusal or unknown status regarding radiotherapy significantly correlated with an adverse prognosis in patients with stage I CRC. We identified certain key clinicopathological features of patients with stage I CRC and demonstrated the survival benefits of radiotherapy, offering a new perspective on stage I CRC follow-up and treatment recommendations.

Prevalence and Impact of Concomitant Atrial Fibrillation in Patients Undergoing Percutaneous Coronary Intervention for Acute Myocardial Infarction.

Background: Concomitant atrial fibrillation (AF) is associated with an adverse prognosis in patients with acute myocardial infarction (MI). However, it remains unclear whether this is due to a causal effect of AF or whether AF acts as a surrogate marker for comorbidities in this population. Furthermore, there are limited data on whether coronary artery disease distribution impacts the risk of developing AF. Methods: Consecutive patients admitted with acute MI and treated using percutaneous coronary intervention (PCI) at a single centre were retrospectively identified. Associations between AF and major adverse cardiac and cerebrovascular events (MACCEs) over a median of five years of follow-up were assessed using Cox regression, with adjustment for confounding factors performed using both multivariable modelling and a propensity-score-matched analysis. Results: AF was identified in N = 65/1000 (6.5%) of cases; these patients were significantly older (mean: 73 vs. 65 years, p < 0.001), with lower creatinine clearance (p < 0.001), and were more likely to have a history of cerebrovascular disease (p = 0.011) than those without AF. In addition, patients with AF had a greater propensity for left main stem (p = 0.001) or left circumflex artery (p = 0.004) involvement. Long-term MACCE rates were significantly higher in the AF group than in the non-AF group (50.8% vs. 34.2% at five years), yielding an unadjusted hazard ratio (HR) of 1.86 (95% CI: 1.32-2.64, p < 0.001). However, after adjustment for confounding factors, AF was no longer independently associated with MACCEs, either on multivariable (adjusted HR: 1.25, 95% CI: 0.81-1.92, p = 0.319) or propensity-score-matched (HR: 1.04, 95% CI: 0.59-1.82, p = 0.886) analyses. Conclusions: AF is observed in 6.5% of patients admitted with acute MI, and those with AF are more likely to have significant diseases involving left main or circumflex arteries. Although unadjusted MACCE rates were significantly higher in patients with AF, this effect was not found to remain significant after adjustment for comorbidities. As such, this study provided no evidence to suggest that AF is independently associated with MACCEs.

Analysis of Factors Influencing Prognosis and Assessment of 60 Cases of Decompensated Cirrhotic Patients with Portal Hypertension.

To investigate the risk factors for the development of portal hypertension in patients with decompensated cirrhosis and analyze their prognosis. Patients with decompensated cirrhosis who were admitted to our hospital and Qu fu People's Hospital from June 2022 to June 2023 were included in this study. Among them, there were 45 male and 15 female patients, with a median age of 56 (range: 35-77) years. A comparative analysis was performed between Group A (hepatic venous pressure gradient, HVPG <16 mmHg) and Group B (HVPG ≥16 mmHg) patients, along with various clinical outcomes. Multivariate analysis was conducted to explore the risk factors influencing the occurrence of portal hypertension and adverse prognosis in patients with cirrhosis. In Group A patients with portal hypertension, we observed lower levels of aspartate aminotransferase, laminin, serum hyaluronic acid, type III procollagen N-terminal peptide, total bile acids, and cholylglycine acid compared to Group B. On the other hand, levels of alanine aminotransferase, white blood cells, and serum albumin were higher in Group A than in Group B. These differences between the groups were statistically significant (P < 0.05). Multivariate analysis of the aforementioned risk factors indicated that low white blood cell count, high cholylglycine acid levels, and high serum hyaluronic acid levels were identified as independent risk factors for the occurrence of difficult-to-control complications in decompensated portal hypertension among patients with liver cirrhosis (P < 0.05). Liver cirrhosis patients with portal hypertension and multiple risk factors like low white blood cell count and high liver transaminase levels should be cautious regarding the progression of portal hypertension when combined with splenomegaly, liver fibrosis, and bile stasis, as it often indicates a poor prognosis.

S100A6 mediated epithelial-mesenchymal transition affects chemosensitivity of colorectal cancer to oxaliplatin

PurposeTo investigate the mechanism by which S100 calcium-binding protein A6 (S100A6) affects colorectal cancer (CRC) cells to oxaliplatin (L-OHP) chemotherapy, and to explore new strategies for CRC treatment. MethodsS100A6 expression was assessed in both parental and L-OHP-resistant CRC cells using western blotting, quantitative real-time polymerase chain reaction (qRT-PCR), and enzyme-linked immunosorbent assays (ELISA). Lentiviral vectors were utilized to induce the knockdown of S100A6 expression, followed by comprehensive evaluations of cell proliferation, apoptosis, and epithelial-mesenchymal transition (EMT). Additionally, RNA-seq analysis was conducted to identify genes associated with the knockdown of S100A6. ResultsElevated S100A6 expression in CRC tissues correlated with an adverse prognosis in patients with CRC. Higher expression of S100A6 was also observed in L-OHP-resistant CRC cells, which showed enhanced proliferation, migration, invasion, and antiapoptotic capabilities. Notably, the knockdown of S100A6 expression resulted in decreased proliferation, increased apoptosis, and suppression of EMT and tumorigenicity in L-OHP-resistant CRC cells. Transcriptome sequencing reveals a noteworthy association between S100A6 and vimentin expression. Application of the EMT agonist, transforming growth factor β (TGF-β), induces EMT in CRC cells. S100A6 expression positively correlates with TGF-β expression. TGF-β facilitated the expression of EMT-related molecules and reduced the chemosensitivity of L-OHP in S100A6-knockdown cells. ConclusionIn conclusion, the knockdown of S100A6 may overcome the L-OHP resistance of CRC cells by modulating EMT.

Initial lactate levels linked to oliguria in term neonates with perinatal asphyxia

BackgroundOliguria is a sign of impaired kidney function and has been shown to be an early predictor of adverse prognoses in patients with acute kidney injury. The relationship between urine output (UOP) and early lactate levels in neonates with perinatal asphyxia (PA) has not been extensively explored. This study aimed to investigate the link between oliguria during the first 24 h of life and early lactate levels in neonates with PA.MethodsThe medical records of 293 term neonates with asphyxia from 9216 hospitalized newborns were retrospectively analyzed, including 127 cases designated as the oliguria group and 166 cases as controls. Peripheral arterial blood gas after PA and UOP within 24 h after birth were analyzed. Logistic regression analyses and receiver operating characteristic curve analysis were conducted.ResultsOliguria occurred in 43.34% of neonates with PA. The median UOP of the oliguria and control groups were 0.65 and 1.46 mL/kg/h, respectively. Elevated lactate levels after PA are an independent risk factor for oliguria in the following 24 h (p = 0.01; OR: 1.19; 95%CI: 1.04–1.35) and show a moderate discriminatory power for oliguria (AUC = 0.62). Using a cut off value of 8.15 mmol/L, the positive and negative predictive values and the specificity were 59.34%, 63.86%, and 78.30%, respectively.ConclusionNeonates with elevated lactate levels after PA face a risk of oliguria in the following 24 h. Based on early elevated lactate levels after resuscitation, especially ≥ 8.15 mmol/L, meticulously monitoring UOP will allow this vulnerable population to receive early, tailored fluid management and medical intervention.Graphical abstractA higher resolution version of the Graphical abstract is available as Supplementary information

Integrative single-cell transcriptomic analyses reveal the cellular ontological and functional heterogeneities of primary and metastatic liver tumors

BackgroundThe global cellular landscape of the tumor microenvironment (TME) combining primary and metastatic liver tumors has not been comprehensively characterized.MethodsBased on the scRNA-seq and spatial transcriptomic data of non-tumor liver tissues (NTs), primary liver tumors (PTs) and metastatic liver tumors (MTs), we performed the tissue preference, trajectory reconstruction, transcription factor activity inference, cell–cell interaction and cellular deconvolution analyses to construct a comprehensive cellular landscape of liver tumors.ResultsOur analyses depicted the heterogeneous cellular ecosystems in NTs, PTs and MTs. The activated memory B cells and effector T cells were shown to gradually shift to inhibitory B cells, regulatory or exhausted T cells in liver tumors, especially in MTs. Among them, we characterized a unique group of TCF7+ CD8+ memory T cells specifically enriched in MTs that could differentiate into exhausted T cells likely driven by the p38 MAPK signaling. With regard to myeloid cells, the liver-resident macrophages and inflammatory monocyte/macrophages were markedly replaced by tumor-associated macrophages (TAMs), with TREM2+ and UBE2C+ TAMs enriched in PTs, while SPP1+ and WDR45B+ TAMs in MTs. We further showed that the newly identified WDR45B+ TAMs exhibit an M2-like polarization and are associated with adverse prognosis in patients with liver metastases. Additionally, we addressed that endothelial cells display higher immune tolerance and angiogenesis capacity, and provided evidence for the source of the mesenchymal transformation of fibroblasts in tumors. Finally, the malignant hepatocytes and fibroblasts were prioritized as the pivotal cell populations in shaping the microenvironments of PTs and MTs, respectively. Notably, validation analyses by using spatial or bulk transcriptomic data in clinical cohorts concordantly emphasized the clinical significance of these findings.ConclusionsThis study defines the ontological and functional heterogeneities in cellular ecosystems of primary and metastatic liver tumors, providing a foundation for future investigation of the underlying cellular mechanisms.

The prognostic value of ductal adenocarcinoma of the prostate in patients with advanced prostate cancer treated with abiraterone acetate.

167 Background: Previous studies have indicated that ductal adenocarcinoma of the prostate (DA) is associated with adverse prognosis in patients with localized prostate cancer (PCa). However, the clinical significance of DA in advanced PCa remains largely ambiguous. This study endeavors to investigate the relationship between the existence of DA in prostate biopsy specimens and treatment outcomes among patients with advanced PCa receiving abiraterone acetate (AA) therapy. Methods: We retrospectively analyzed data from 440 patients with advanced PCa who received AA at either the metastatic hormone-sensitive (mHSPC, N=123) or castration-resistant PCa (mCRPC, N=317) stage. The presence of DA and its proportion was evaluated based on prostate biopsy specimens. Kaplan-Meier curves and COX regression were used to evaluate the predictive significance of DA on AA efficacy, including PSA response, PSA progression-free survival (PSA-PFS), and radiographic progression-free survival (rPFS). Results: In aggregate, DA was detected in 35/440 (8.0%) patients, with 13/440 (3.0%) and 22/440 (5.0%) men harboring DA&lt;5% and ≥5%, respectively, in the total tumors. The overall PSA response rate in the entire cohort was 302/440 (68.6%), and it was comparable for people with and without DA, with both groups having a response rate of 68.6%. Of note, compared with patients without DA, men with DA have significantly longer median PSA-PFS (mPSA-PFS, 12.1- vs. 25.0-Mo, P=0.005) and median rPFS (mrPFS, 19.8 vs. 38.2-Mo, P=0.034). Subgroup analysis based on DA proportion further revealed that in comparison with PCa without DA, DA≥5% was an indicator of favorable PSA-PFS (HR, 95%CI: 0.28, 0.14-0.56, p&lt;0.001) and rPFS (HR, 95%CI: 0.35, 0.18-0.72, p=0.004), while DA&lt;5% was not. In multivariate COX regression analysis, after adjusting by clinicopathological factors, including mCRPC/mHSPC stage, ISUP grading, metastatic burden, pain score and pretreatment hemoglobin, alkaline phosphatase, and lactate dehydrogenase, DA≥5% was still independently associated with better therapeutic efficacy of AA treatment (PSA-PFS: HR, 95%CI: 0.36, 0.17-0.74, p&lt;0.001; rPFS: HR, 95%CI: 0.47, 0.23-0.96, p=0.040). Conclusions: A DA proportion ≥5% in the tumor is related to improved treatment efficacy for individuals with advanced PCa receiving AA. Thus, in the pathological diagnosis of PCa, it is necessary to routinely report the presence and proportion of DA in order to aid with treatment decision-making.
