Lymphocyte subsets in pediatric acute lymphoblastic leukemia and their prognostic value.

To study the changes of lymphocyte subsets in children with acute lymphoblastic leukemia (ALL) at initial diagnosis and compare them with those of healthy children and patients who have achieved complete remission (CR). Furthermore, we aim to analyze the prognostic significance of lymphocyte subsets in these patients. From May 2011 to December 2015, 405 children with ALL were enrolled in this study. Peripheral blood was collected at the time of diagnosis, and lymphocyte subsets were detected by flow cytometry. Then, the percentages of lymphocyte subsets in each group were compared. In addition, survival and prognostic factor analyses were performed to determine the prognostic value of lymphocyte subsets. Lymphocyte subsets in children with ALL were dramatically different from those in healthy children and patients achieving CR. Additionally, lymphocyte subsets were correlated with different minimal residual disease and risk parameters. Furthermore, percentages of CD3+ T cells and CD4+ T cells and the ratio of CD4/CD8 were associated with different clinical outcomes. Multivariate analysis demonstrated the percentage of CD4+ T cell as an independent predictor for clinical prognosis. Lymphocyte subsets in pediatric ALL undergo dramatic changes and were related to prognosis, especially CD4+ T cells.

Identification and validation of a prognostic model based on immune-related genes in ovarian carcinoma.

A novel valuable prognostic model has been developed on the basis of immune-related genes (IRGs), which could be used to estimate overall survival (OS) in ovarian cancer (OC) patients in The Cancer Genome Atlas (TCGA) dataset and the International Cancer Genome Consortium (ICGC) dataset. This prognostic model was engineered by employing LASSO regression in training cohort (TCGA dataset). The corresponding growth predictive values of this model for individualized survival was evaluated using survival analysis, receiver operating characteristic curve (ROC curve), and risk curve analysis. Combined with clinical characteristics, a model risk score nomogram for OS was well built. Thereafter, depended on the model risk score, patients were divided into high and low risk subgroups. The survival difference between these subgroups was measured using Kaplan-Meier survival method. In addition, correlations containing pathway enrichment, treatment, immune cell infiltration and the prognostic model were also analyzed. We established the ovarian cancer cell line W038 for this study and identified the performances of GBP1P1 knockdown on a series of activities including cellular proliferation, apoptosis, migration, and invasion of W038 cells in vitro. We constructed a 25-genes prognostic model (TNFAIP8L3, PI3, TMEM181, GBP1P1 (LOC400759), STX18, KIF26B, MRPS11, CACNA1C, PACSIN3, GMPR, MANF, PYGB, SNRPA1, ST7L, ZBP1, BMPR1B-DT, STAC2, LINC02585, LYPD6, NSG1, ACOT13, FAM120B, LEFTY1, SULT1A2, FZD3). The areas under the curves (AUC) of 1, 2 and 3 years were 0.806, 0.773 and 0.762, in the TCGA cohort, respectively. Besides, the effectiveness of the model was verified using ICGC testing data. Univariate and multivariate Cox regression analysis exposes the risk score as an independent prognosis predictor for OS both in the TCGA and ICGC cohort. In summary, we utilized comprehensive bioinformatics analysis to build an effective prognostic gene model for OC patients. These bioinformatic results suggested that GBP1P1 could act as a novel biomarker for OC. GBP1P1 knockdown substantially inhibited the proliferation, migration, and invasion of W038 cells in vitro, and increased the percentage of apoptotic W038 cells. The analyses of genetic status of patients with 25-genes model might improve the ability to predict the prognosis of patients with OC and help to select patients suit able to therapies. Immune-related gene GBP1P1 might serve as prognostic biomarker for OC.

The prognosis of acute myocardial infarction due to stent thrombosis after 2nd generation drug eluting stents era (comparative study with acute myocardial infarction due to plaque rupture or erosion)

Abstract Backgrounds Stent thrombosis (ST) is a rare complication after percutaneous coronary intervention (PCI), and more than 70% of ST cases result in acute myocardial infarction (AMI). Although a new generation of drug-eluting stents (DES) and newer antiplatelet therapies have been shown to reduce the incidence of ST, ST-related AMI continues to be observed in contemporary practice. The prevalence and prognosis of ST results in AMI have not been well evaluated after the 2nd generation DES (G2-DES) era. Purpose The purpose of this study was to evaluate the prevalence and prognosis of AMI due to ST after the G2-DES era compared with AMI due to plaque rupture or erosion. Methods Among 6601 AMI patients enrolled in the Mie ACS registry from January 2013 to November 2022, 6273 AMI patients with AMI due to ST(ST) and AMI due to plaque rupture and erosion (AMI:P) were included for this analysis after excluding other types of AMI. ST was confirmed by angiography. The primary endpoint was defined as all-cause mortality, and revascularization after PCI for AMI was also evaluated. Results Seventy-eight patients, or 1.2% of all AMI in this study, had AMI due to ST, including early ST n=13 (16.7%), late ST n=4 (5.1%), and very late ST n=61 (78.2%). Stent types were G2-DES n=35 (44%), G1-DES n=18 (23.1%), bare metal stent (BMS) n=12 (15.4%), and unknown n=13 (16.7%). According to the KM survival curve, the 30-day mortality rate of ST was 2.6%, while the AMI:P rate was 6.7%, which was not statistically significant, but the ST was half the mortality rate. Furthermore, in the landmark analysis, the 2-year mortality rates were 6.2% for ST and 7.0% for AMI:P (P=0.66, Figure 1). ST was not an independent predictor of poor prognosis by multivariate Cox regression analysis. Even after the propensity score matching analysis as a sensitivity analysis, ST was not an independent predictor of poor prognosis in AMI patients. Among ST patients, 82.2% were treated with balloon angioplasty (without additional stenting) at the time of AMI, whereas 9.7% of AMI:P patients were treated with balloon angioplasty (P&amp;lt;0.001). Compared to patients with AMI:P, patients with ST had a higher incidence of revascularization after PCI for AMI within 2 years (21.8% vs. 11.2%; P=0.02, Figure 2A). Multivariate Cox regression analysis also showed that ST was an independent predictor of revascularization after PCI for AMI with a hazard ratio of 2.00 (P&amp;lt;0.01, Figure 2B). Conclusion The prognosis of ST patients tended to be better than that of AMI:P patients. The proportion of ST in AMI has decreased in the G2-DES era, and the higher proportion of VLST in ST suggests that its prognosis may be better than that of AMI:P . However, the rate of revascularization is higher in ST patients because stenting was not performed in the acute phase of PCI for AMI, and the appropriate use of stents depending on the type of ST may lead to a reduction in revascularization.Figure1Figure2

What is the true normal: comparison of different equations for estimating peak oxygen uptake for outcome prediction in heart failure

Abstract Background and Objectives One of the strongest prognostic parameters obtained during Cardiopulmonary exercise testing (CPET) in patients with heart failure (HF) is the peak oxygen uptake (pVO2), as a standalone or as a percentage of the predicted peak oxygen uptake (ppVO2) reached. However, traditional standards by which ppVO2 is calculated have limitations, having been derived from small cohorts, lacking portability and poorly represented by women. Thus, we aim to compare the FRIEND Registry equation to previously used methods of calculating ppVO2 as it relates to prognostic value imparted by the percentage of ppVO2 (%ppVO2) reached during CPET and portability to the Portuguese HF population. Methods Single centre retrospective study of patients with HF with LVEF &amp;lt; 50% who underwent CPET between 2015-2021. Patients who did not reach RER≥ 1.05 were excluded from our analysis. All tests were evaluated and ventilatory thresholds determined by 3 independent, experienced operators. ppVO2 was calculated according to 1) the Wasserman equation; 2) the Wasserman equation using ideal body weight; 3) the Neder equation, 4) the SHIP equation and 5) the FRIEND equation. Our primary endpoint was a composite of CV death, urgent transplant or left ventricular assist device implantation and HF hospitalization. Results We included 238 patients (mean age 59 ± 11 years, 83% males). The HF aetiology was mostly ischemic in nature (68%), with LVEF of 34 ± 9% and median NTproBNP of 776 (2566 – 2342) pg/mL. Most patients (67%) were in class NYHA I-II and with high prevalence of GDMT (93% ACEi/ARB; 97% beta-blockers and 64% on MRA). Mean BMI in this group was 27.3 ± 4.7 kg/min. Patients performed CPET on a treadmill with a protocol adjusted to their predicted exercise capacity. Mean pVO2 was 18.1 ± 6.2mL/kg/min, corresponding to a median %ppVO2 that ranges from 51 ± 16% to 71 ± 22%, depending on the equation that is used. Mean VE/VCO2 Slope was 42 ± 13 and 48 % (n = 98) of patients showed exercise oscillatory ventilation (EOV). Mean ppVO2 as per the FRIEND and Wasserman equations was 18.9 ± 6.6 and 21.2 ± 4.5 mL/kg/min, with no statistically significant difference between both. %ppVO2 as calculated through all equations was an independent predictor of prognosis on multivariate analysis adjusted for LVEF, NTproBNP and VE/VCO2 Slope (p &amp;lt; 0.001 for values derived from all equations). However, the FRIEND and Wasserman equations showed a slight advantage over the remaining 2 equations, with higher AUC on ROC curve analysis (see figure). Conclusions In our population of Portuguese patients with HF, both the FRIEND registry and Wasserman equations for predicting pVO2 yielded strong prognostic power. However, these equations provide different absolute predicted VO2 values for the same patients and thus should not be used interchangeably. Standardisation of the type ppVO2 equation used should be recommended by local scientific societies.

Early postoperative Fibrinogen-to-Albumin Ratio prognosticate 6-month procedural success in patients undergoing orthotopic heart transplantation

Abstract Background The Fibrinogen-to-Albumin ratio (FAR) has emerged as a novel biomarker, integrating liver function and inflammatory reaction with proven prognostic value in heart failure (HF) patients. This study aims to evaluate its significance in advanced HF patients treated with orthotopic heart transplantation (HTx). Methods Mean fibrinogen, albumin and FAR values were analyzed one week post-HTx. The primary endpoint of the study was 6-month all-cause mortality. Regression models incorporating parameters significantly different between survivor and deceased groups (troponin, potassium, asparagine aminotransferase [AST]) were developed to assess predictive value of FAR. Additionally, the Spearman's rank correlation between FAR and inflammatory biomarkers (C-reactive protein [CRP], procalcitonin, white blood cells (WBC)] and liver enzymes [AST, alanine aminotransferase [ALT], gamma-glutamyl transpeptidase [GGTP]) were calculated. Results The analysis included 104 patients undergoing HTx with a median age of 53 years (44.5-62.5), 82% were male, 44% had ischaemic aetiology of HF. Within 6 months post-HTx 17 patients (16%) died. Mean fibrinogen in all patients was (3.18 ± 0.83), albumin (3.17 ± 0.35) and FAR (1.01 ± 0.28). Deceased patients exhibited lower 1 week post HTx mean fibrinogen (2.46 ± 1.13) compared to survivors (3.30 ± 0.70), lower albumin (2.93 ± 0.43) vs. (3.21 ± 0.32), and lower FAR median (0.73, 0.53-1.16) vs. (0.99, 0.88-1.18), all p&amp;lt;0.05. The post-HTx fibrinogen independently predicted death: (RR 0.37, p=0.003, 95% CI [0.19,0.71]), as did post-HTx albumin: (RR 0.21, p=0.05, 95% CI [0.04,1.0]). FAR was also an independent risk factor: (RR 0.08, p=0.009, 95% CI [0.01,0.54]). There were significant correlations between FAR and CRP (R=0.30, p=0.003), and GGTP (R=0.25, p=0.045). FAR was not significantly correlated with procalcitonin, WBC, AST and ALT. Conclusions Early post-HTx fibrinogen, albumin and FAR are independent predictors of an unfavorable prognosis in HF patients undergoing HTx. In contrast to chronic HF, early post-HTx FAR was inversely correlated with mortality. The calculated correlation between FAR, inflammatory markers and liver enzymes suggests limited association with inflammatory processes and liver function in this population.

Echocardiographic evaluation of right ventricle to pulmonary artery coupling in patients undergoing transcatheter aortic valve implantation: a systematic review and meta-analysis

Abstract Background Right Ventricle to Pulmonary Artery (RV/PA) uncoupling, which depicts the inability of RV contractility to match the increasing RV afterload, has recently gained recognition as a simple echocardiography parameter to aid prognosis judgment in patients with RV dysfunction. In Aortic Stenosis (AS) patients, the extent of RV dysfunction and Pulmonary Hypertension (PH) has been linked with poor outcomes, but the prognostic value of RV/PA uncoupling in AS patients undergoing TAVI has not been well-defined. Purpose To investigate the prognostic value of RV/PA uncoupling and its association with echocardiographic parameters in AS patients undergoing TAVI. Methods We conducted a systematic search through Pubmed and Embase to include studies up to February 2024. Studies were eligible if they evaluated the prognostic performance of RV/PA uncoupling in AS patients undergoing TAVI. Random-effects model were employed to pool the adjusted Hazard Ratio (aHR) with inverse-variance weighting method or Relative Risk (RR) with 95% Confidence Interval (95% CI) using Mantel-Haenszel test for categorical outcomes or Weighted Mean Difference (WMD) for numerical outcomes. Risk of bias assessment was conducted using the Newcastle Ottawa Scale (NOS). Results Thirteen studies were included. Out of 4,146 patients, 55.21% were reported to have RV-PA uncoupling prior to TAVI. RV/PA uncoupling was customarily assessed with TAPSE/PASP ratio, with threshold for uncoupling ranging between &amp;lt;0.31–&amp;lt;0.63 mm/mmHg. Follow-up period ranged between 6–65 months. Patients with baseline RV/PA uncoupling had lower LVEF (WMD -9.94% [-4.36– -15.53%]; I2 = 78%), lower TAPSE (WMD -4.98 mm [95% CI -1.15– -8.80]; I2 = 95%), and higher PASP (WMD 19.77 [95% CI 17.02–22.51]; I2 = 0%) compared to patients with RV/PA coupling at baseline. Baseline RV-PA uncoupling was an independent predictor of all-cause mortality (pooled aHR = 2.26 (95% CI 1.36–3.76); I2 = 77%) and composite endpoint of mortality and adverse cardiac or cerebrovascular events (pooled aHR = 2.07 (1.30–3.29); I2 = 24%). However, RV/PA uncoupling was not significantly associated with a higher risk of permanent pacemaker implantation after TAVI (pooled Risk Ratio 1.02 [0.70–1.47]; I2 = 0%). Conclusion Pre-procedural RV/PA uncoupling emerges as an independent predictor of worse prognosis in AS patients undergoing TAVI, contributing to a better understanding of the impact of this parameter on patient outcomes.

Prognostic significance of right ventricular dysfunction in patients with TTR amyloidosis

Abstract Background Transthyretin amyloidosis (ATTR) is increasingly recognized as a cause of heart failure (HF) that now benefits from effective treatment. While the role of right ventricular (RV) systolic dysfunction has been widely accepted as an independent predictor of poor prognosis in HF patients, its implications in ATTR remain poorly understood. Right ventricular free wall strain (FWS) over pulmonary arterial systolic pressure (PAsP) has been recently proposed as an accurate and sensitive tool to evaluate RV function and its coupling to the afterload. Purpose Our study sought to analyze whether indexing FWS to PASP should integrate the set of fundamental data we have to assess the prognosis of ATTR patients. Methods 191 consecutive patients diagnosed with ATTR were enrolled. A comprehensive echocardiographic examination was part of the systematic evaluation. The primary outcome was a composite of cardiovascular mortality and hospitalization caused by heart failure worsening. Results After a median follow-up of 24 months, among patients with ATTR [median age 82 (77, 85), 89.5% male], the primary composite outcome occured in 26%. Cardiovascular mortality rate was 7.3% and the hospital event rate was 18.8%. Tricuspid annular plane systolic excursion (TAPSE), FWS, TAPSE/PAsP and PAsP were univariately significant risk factors for adverse outcome. In multivariate Cox regression analysis, after adjustment of confounding factors, FWS/PASP emerged as an independent predictor of the composite endpoint of cardiac death and rehospitalization (HR 1.61, 95% CI 1.07-2.42, p=0.021). Based on receiver-operating characteristic analysis, the optimal FWS/PASP cut-off value for event prediction was 42.5% (area under the curve = 0.749, p = 0.001). Conclusion Right ventricular function assessed with speckle-tracking echocardiography is an independent prognostic marker for cardiac mortality and heart failure hospitalization in patients with ATTR. FWS/PAsP should be integrated into regular clinical practice for a better evaluation and follow-up of ATTR patients.

Association of PCSK6 rs1531817(C/A) polymorphism with the prognosis and coronary stenosis in premature myocardial infarction patients: a prospective cohort study

Abstract Background An increasing proportion of younger patients are currently hospitalized for acute myocardial infarction. Exploring the factors affecting coronary artery lesions and prognosis in patients with premature myocardial infarction (PMI) from a genetic perspective is of great significance to clinical management. Proprotein convertase subtilisins/kexins 6(PCSK6), a member of the PCSK family, functions in protein hydrolytic cleavage. It has been shown that PCSK6 polymorphisms are associated with carotid atherosclerosis. Purpose This research intended to evaluate the relationship between the PCSK6 rs1531817 polymorphism and the prognosis of PMI patients and their coronary stenosis. Methods This study was a prospective cohort study, which consecutively included 605 patients with PMI who underwent emergency PCI from January 2017 to August 2022 at X Hospital. Using the Massarray technique, the single nucleotide polymorphisms(SNPs) of PCSK6 rs1531817 were identified, and the patients underwent follow-up for 12 to 72 months, with major adverse cardiovascular events (MACEs) as the outcome. Analyze the relationship between patients' SNPs, Gensini score(GS), Triple vessel diseases(TVD), and MACEs. Results In PMI patients with PCSK6 rs1531817 CA+AA genotypes, ApoA1/ApoB levels were higher than in patients with CC genotype, and TC/HDL levels were lower (p &amp;lt; 0.05). Logistic regression analysis showed that the PCSK6 rs1531817 polymorphism (Dominant model: CA+AA vs.CC) was significantly correlated with the GS (high vs. low GS, adjOR=0.297, 95%CI:0.139-0.632, p=0.002; high vs. medium GS, adjOR=0.449, 95%CI:0.211-0.956, p=0.038), and it was correlated with the number of coronary artery lesions (TVD vs. SVD, adjOR=0.420, 95%CI:0.226-0.782, p=0.006; TVD vs. DVD, adjOR=0.406, 95%CI:0.214-0.773, p=0.006). According to multivariate Cox regression analysis, the PCSK6 rs1531817 dominant model was associated with the MACEs in PMI patients (adjHR=0.454, 95%CI:0.269-0.766, p=0.003). The mediation effect results showed that ApoA1/ApoB played a partially mediating role in the association between PCSK6 rs1531817 polymorphism and the severity of coronary stenosis (the effect leading to high GS and TVD accounted for 14.6% and 8.3% respectively), TC/HDL and TVD partially parallel mediated the association between PCSK6 rs1531817 polymorphism and MACEs (effect proportions were 8.1% and 17.1%, respectively). Conclusion Carrying the PCSK6 rs1531817 mutant A allele is an independent protective predictor of severe coronary stenosis and long-term prognosis in patients with PMI. Patients with the PCSK6 CA+AA genotypes have milder coronary stenosis partially because they have higher levels of ApoA1/ApoB; in addition, these patients have a better long-term prognosis partially because they have lower TC/HDL levels and fewer TVD patients.Figure 1.ApoA1/ApoB and TC/HDL were compareFigure 2.Correlation of PCSK6 rs1531817 pol

SRSF12 is a prognostic biomarker involved in immune infiltration in acute myeloid leukemia

ABSTRACT Background Acute myeloid leukemia (AML) is a disease characterized by the proliferation of abnormal cells originating from blood stem cells. Understanding the pathogenesis and progression of AML, as well as identifying molecular markers for early diagnosis and prognosis assessment, is of paramount importance. Methods The AML dataset was obtained from the Cancer Genome Atlas (TCGA), while the normal sample dataset was derived from the Genotype-Tissue Expression(GTEx) dataset. Furthermore, the association between SRSF12 expression and drug response was assessed using the Cancer Therapeutic Response Portal (CTRP) database to evaluate its potential therapeutic value. Finally, SRSF12 expression in AML cells was measured using quantitative real-time PCR (qRT-PCR). Result The difference in SRSF12 expression between 13 types of tumors and normal tissue samples was found to be statistically significant (P < 0.05). SRSF12 exhibited predominantly high expression in AML, indicating its potential as a diagnostic and prognostic marker for AML patients. High expression of SRSF12, along with age and cytogenetic risk, emerged as independent predictors of favorable prognosis in AML patients (P < 0.05). PCR demonstrated a significant increase in SRSF12 expression in AML patients. Conclusion Overall, our findings suggest that the high expression of SRSF12 in AML patients is a poor prognostic factor, which may provide a new option for the diagnosis, and targeted therapy of AML.

Impact of fasting blood glucose on prognosis after acute large vessel occlusion reperfusion: results from a multicenter analysis

ObjectiveTo analyze the effect of fasting blood glucose levels after reperfusion of acute large vessel occlusion (ALVO) on patient functional prognosis.MethodsRetrospectively included ALVO patients from three large stroke centers in China, all of whom achieved vascular reperfusion after mechanical thrombectomy or bridging thrombolysis. The prognosis scores of all patients at 90 ± 7 days post-recanalization were categorized into a good prognosis group (mRS 0–2) and a poor prognosis group (mRS 3–6). The relationship between mean blood glucose levels at 72 h post-recanalization and prognosis was explored using multivariable logistic regression analysis. Then we measured the area under the ROC curve for all factors to assess their predictive performance.Results(1) Totally 2,056 patients were included in the study, with 1,488 males and 568 females. There were 1,370 patients in the good prognosis group (mRS 0–2) and 686 in the poor prognosis group (mRS 3–6). (2) The two groups exhibited significant differences in terms of age, preoperative mRS score, history of diabetes, and mean fasting blood glucose (MFBG) (p &amp;lt; 0.001). (3) With 90-day mRS as the outcome variable, all independent variables were included in Univariate and multivariate regression analyses analysis, and the results showed that: age, preoperative mRS score, history of diabetes, and MFBG are all independent predictors of prognosis after recanalization of ALVO, with MFBG demonstrating a higher predictive power than the other factors (AUC = 0.644).ConclusionVarious factors are correlated with the prognosis in patients who have undergone ALVO recanalization. Notably, the MFBG level demonstrates a significant predictive value for outcomes within the first 72 h following the recanalization procedure.

SHARPIN is a novel gene of colorectal cancer that promotes tumor growth potentially via inhibition of p53 expression.

Colorectal cancer (CRC) is widely prevalent and represents a significant contributor to global cancer‑related mortality. There remains a pressing demand for advancements in CRC treatment modalities. The E3 ubiquitin ligase is a critical enzyme involved in modulating protein expression levels via posttranslational ubiquitin‑mediated proteolysis, and it is reportedly involved in the progression of various cancers, making it a target of recent interest in anticancer therapy. In the present study, using comprehensive expression analysis involving spatial transcriptomic analysis with single‑cell RNA sequencing in clinical CRC datasets, the ubiquitin‑associated protein Shank‑associated RH domain interactor (SHARPIN) was identified, located on amplified chromosome 8q, which could promote CRC progression. SHARPIN was found to be upregulated in tumor cells, with elevated expression observed in tumor tissues. This heightened expression of SHARPIN was positively associated with lymphatic invasion and served as an independent predictor of a poor prognosis in patients with CRC. In vitro and in vivo analyses using SHARPIN‑overexpressing or ‑knockout CRC cells revealed that SHARPIN overexpression upregulated MDM2, resulting in the downregulation of p53, while SHARPIN silencing or knockout downregulated MDM2, leading to p53 upregulation, which affects cell cycle progression, tumor cell apoptosis and tumor growth in CRC. Furthermore, SHARPIN was found to be overexpressed in several cancer types, exerting significant effects on survival outcomes. In conclusion, SHARPIN represents a newly identified novel gene with the potential to promote tumor growth following apoptosis inhibition and cell cycle progression in part by inhibiting p53 expression via MDM2 upregulation; therefore, SHARPIN represents a potential therapeutic target for CRC.

Loss of vimentin expression in preoperative biopsies independently predicts poor prognosis, lymph node metastasis and recurrence in endometrial cancer

BackgroundPrecise preoperative risk classification of endometrial cancer is crucial for treatment decisions. Existing clinical markers often fail to accurately predict lymph node metastasis and recurrence risk. Loss of vimentin expression has emerged as a potential marker for predicting recurrence in low-risk endometrial cancer patients. We assessed whether vimentin expression in preoperative biopsies predicts poor prognosis and lymph node metastasis in a large multicentre cohort.MethodsVimentin expression was evaluated using immunohistochemistry in 1483 patients diagnosed with endometrial cancer across 14 hospitals in Europe. Expression levels of vimentin were analyzed in conjunction with clinical characteristics for predicting disease-specific survival and lymph node metastases.ResultsVimentin loss was significantly associated with aggressive disease and poor survival. Adjusted for clinicopathological variables, vimentin remained independently prognostic with a hazard ratio (HR) of 1.68 (95% CI 1.16–2.42, P = 0.006). Vimentin expression remained independently prognostic in endometrioid endometrial cancer- and FIGO staged 1 patient. Interestingly, vimentin loss independently predicted lymph node metastases, with an HR of 1.83 (95% CI 1.13–2.95, P = 0.014).ConclusionsLoss of vimentin in preoperative biopsies serves as an independent predictor of poor prognosis and lymph node metastases. Incorporating vimentin as a clinical marker can improve risk stratification and treatment decisions.

Three-Month Mortality in Nonhaematological Patients with Chronic Pulmonary Aspergillosis: Differences between Subtypes.

Objectives: Chronic pulmonary aspergillosis (CPA) is a fungal lung infection characterised by the slowly progressing destruction of the lung parenchyma and has four main subtypes. The objective of this work was to evaluate the epidemiology of CPA in our area and evaluate the involvement of the different subtypes in mortality. Methods: This was a descriptive longitudinal retrospective study developed in three tertiary hospitals in Spain. Among all patients admitted with a pulmonary aspergillosis diagnosis, we selected those who fulfilled the criteria for chronic aspergillosis according to the criteria of Denning, excluding those with a haematological disorder. Results: Among 409 inpatients recorded as having a pulmonary aspergillosis infection, only 76 (18.5%) fulfilled the criteria for CPA, with an estimated incidence of 0.67 cases/100,000 inhabitants/year. The subtypes detected were subacute invasive aspergillosis (SAIA) in 33 (43.4%) patients, simple aspergilloma (SA) in 25 (32.9%) patients, cavitary chronic aspergillosis (CCPA) in 13 (17.1%) patients, and chronic fibrosis (CFPA) in five (6.5%) patients. The overall three-month mortality rate was 23%, which was higher in SAIA patients. The predictors of early mortality were age > 65 years (OR 3.0 CI 95 1.0-9.5 p = 0.043) and the SAIA subtype vs. other subtypes (OR 3.1 CI 95 1.0-9.5 p = 0.042). Conclusions: The incidence rate estimated was inferior to that previously reported. The three-month mortality in patients with CPA was high, with older age and the SAIA subtype being the variable independent predictors of a worse prognosis.

Examination of Sarcopenia with Obesity as a Prognostic Factor in Patients with Colorectal Cancer Using the Psoas Muscle Mass Index

Background: Sarcopenia, the age-related loss of muscle mass, is a negative prognostic factor in gastrointestinal cancer. Sarcopenia combined with visceral obesity (sarcopenic obesity) is associated with poor outcomes. We explored the influence of obesity and other factors on the prognosis of patients with colorectal cancer diagnosed with sarcopenia. Methods: We enrolled 211 patients with colorectal cancer diagnosed with preoperative sarcopenic obesity who underwent radical resection at Osaka University Hospital between January 2009 and January 2012. Muscle mass was assessed using the psoas muscle mass index. Obesity was evaluated by measuring the visceral fat area in the umbilical region. Patients were categorized into two groups: sarcopenia with obesity (SO) and sarcopenia without obesity (non-SO). Overall survival, cancer-specific survival, and cancer-related relapse-free survival (CRRFS) were compared between the two groups. Patient characteristics, including age, sex, body mass index, serum albumin, C-reactive protein, tumor markers, prognostic nutritional index (PNI), modified Glasgow prognostic score (mGPS), and geriatric nutritional risk index (GNRI), were also analyzed. Results: CRRFS was significantly shorter in the SO group than in the non-SO group (p = 0.028). PNI, mGPS, and GNRI were not identified as significant prognostic factors for CRRFS. Multivariate analysis highlighted sarcopenic obesity, elevated carcinoembryonic antigen levels, and unfavorable histological types as significant predictors of poor CRRFS outcomes. Conclusions: Sarcopenic obesity is an independent predictor of poor prognosis in patients with CRC. Thus, interventions aimed at increasing muscle mass and reducing visceral fat could potentially improve the prognosis of these patients.

Treatment strategy for cervical lymph node metastases from early-stage tongue and floor of the mouth squamous cell carcinoma using tumour budding and depth of invasion as predictors.

This study aimed to determine whether elective neck dissection can help improve outcomes in early-stage tongue and floor squamous cell carcinoma (SCC) by statistically analysing the relationship between information obtained from biopsy specimens and the incidence and prognosis of cervical lymph node metastasis (CLM). Biopsy specimens of 103 patients diagnosed with early cT1-T2 cancer of the tongue and floor of the mouth were included. Multivariate analysis showed that the three parameters significantly correlated with CLM, and univariate analyses showed that budding score (BS) ≥ 5 and pathological depth of invasion (pDOI) ≥ 5mm were independent risk factors for CLM. There were significant differences in the 5-year cumulative disease-specific survival between the BS < 5 and BS ≥ 5 groups, the pDOI < 5mm and pDOI ≥ 5mm groups, and the positive and negative budding and depth of invasion (BD) score groups. In early-stage tongue and floor of the mouth cancers with maximum tumour diameter ≤ 20mm, it may be necessary to treat occult CLM during initial surgery based on the following preoperative criteria: pDOI ≥ 5mm or BS ≥ 5 in biopsy specimens and DOI ≥ 8mm on imaging. The BD model exhibited the highest specificity and proved helpful for CLM prediction. pDOI ≥ 5mm and BS ≥ 5 were independent predictors of CLM and prognosis in early-stage tongue and floor of the mouth cancers with a maximum tumour diameter of 20mm.

Prognosis of Acute HEV Infection in Patients With Liver Cirrhosis: A Retrospective Study of 628 Chinese Patients.

Acute hepatitis E virus infection is a serious global health problem, which a significant cause of morbidity and mortality. The aim of the present study was to characterise the clinical features and therapeutic response of patients with acute HEV infection and identify risk factors for poor prognosis. In a retrospective study from 01 January 2014 to 01 Januray 2022, we collected baseline data from all patients eligible for acute hepatitis E virus (HEV) infection and followed up with all patients via interviews and medical records. We explored the clinical feature of Chinese patients with acute HEV infection. The follow-up data of patients were used to identify risk factors for poor prognosis. In total, 628 acute hepatitis E (AHE) patients fulfilled the inclusion criteria and did not meet the exclusion criteria. Among them, 452 were males and 176 were females (M:F = 2.57:1). The median age at diagnosis was 57.0 years (interquartile range: 46-64 years). The median baseline serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBIL) were elevated in this cohort (642.3 U/L, 216.2 U/L, 104.1 μmol/L, respectively). The median hospitalisation duration was 16 days. Compared with patients without other liver diseases, patients with liver cirrhosis show lower baseline ALT and AST level, poorer coagulation indices and higher MELD scores. According to multivariate analysis, liver cirrhosis, high MELD score, low albumin concentration was found to be independent predictors of poor prognosis in patients with AHE. Our study used a lager sample size to validate that some demographic and serological features were quite different between patients with/without CLDs. Liver cirrhosis was a significant independent predictor of poor prognosis in acute HEV hepatitis.

Grading carcinoembryonic antigen levels can enhance the effectiveness of prognostic stratification in patients with colorectal cancer: a single-centre retrospective study.

This study developed a refined carcinoembryonic antigen (CEA) grading system using CEA cut-off points of 5, 20 and 50 ng/mL and to explore the prognostic value of CEA grading in predicting the progression-free survival (PFS) and overall survival (OS) of colorectal cancer (CRC) patients. A retrospective cohort study. First Affiliated Hospital of Guangxi Medical University. 1107 CRC patients who received surgical treatment. Survival analysis was conducted using the Kaplan-Meier method and compared using the log-rank test. A Cox regression model with a 95% CI was used to evaluate the independent prognostic risk factors for CRC. Prognostic nomograms were constructed to predict the 1-5-year PFS/OS. Elevated serum CEA levels are often indicative of recurrence and death in CRC patients. Higher CEA levels were significantly associated with more aggressive tumour phenotypes. The CEA grading system was an independent predictor of prognosis in CRC patients and effectively stratified PFS (62.0% vs 51.2% vs 33.7% vs 20.2%, p<0.001) and OS (64.7% vs 54.4% vs 36.6% vs 22.5%, p<0.001) in CRC patients. As the CEA grade increased, the risk of poor prognosis gradually increased in a gradient manner, with an approximately 10% difference in risk grade between each CEA grade. The internal validation cohort further confirmed that CEA grade remains an effective prognostic factor for the survival of CRC patients. Prognostic nomograms, which integrate individual characteristics, tumour features and CEA grading, provide a more comprehensive prognostic evaluation for CRC patients. The CEA grading system is an independent predictor of prognosis for CRC patients and can effectively stratify PFS and OS.

Clinical characteristics of SARS-CoV-2 Omicron pneumonia in immunocompromised and immunocompetent patients: A retrospective cohort study

ObjectivePrevious studies evaluating the differences in COVID-19 mortality rates between immunocompromised patients and other patient groups have shown conflicting findings. This research aimed to compare the mortality rates of immunocompromised and immunocompetent patients during the Omicron-dominant period of the SARS-CoV-2 pandemic, and to identify factors associated with prognosis. MethodsWe conducted a retrospective analysis of 1085 adult patients (aged ≥18 years) admitted with COVID-19 pneumonia to the China-Japan Friendship Hospital between December 1, 2022, and January 31, 2023. We assessed the prevalence of comorbidities, incidence of co-infections and nosocomial infections, and 30-day mortality. ResultsAmong the 1085 patients, 254 were immunocompromised, and 831 were immunocompetent. Immunocompromised patients had higher rates of non-invasive ventilation use (30.3 % vs. 21.1 %), invasive ventilation (12.2 % vs. 5.3 %), and 30-day mortality (19.7 % vs. 13.7 %) compared to immunocompetent patients. However, overall mortality rates did not significantly differ based on immunocompromised status. Cox regression analysis identified that elevated troponin T (≥0.15 ng/mL), respiratory failure, high lactate dehydrogenase (≥272.5 U/L), elevated D-dimer (≥1.295 mg/L), increased C-reactive protein (≥90 mg/L), elevated interleukin-6 (>11.67 ng/L), high peripheral blood neutrophil count (>9.84 × 10⁹/L), and immunocompromised status were independent predictors of poor COVID-19 prognosis. In the immunocompetent group, current smoking and a history of interstitial lung disease were related to a worse prognosis. ConclusionsCOVID-19 pneumonia due to the Omicron variant may lead to worse outcomes in immunocompromised patients. In immunocompetent patients, careful monitoring is essential for those with respiratory failure, smoking history, or interstitial lung disease to prevent adverse outcomes.
