Association between life’s essential 8 and frailty status among cancer survivors in the United States: a cross-sectional analysis

BackgroundFrailty not only affects disease survival but also impacts the long-term function and quality life of all adults diagnosed with and/or treated for cancer.The American Heart Association has introduced Life’s Essential 8 (LE8) as a novel metric for assessing cardiovascular health. Currently, LE8’s application in evaluating the frailty of cancer survivors remains unreported. This research seeks to explore the connection between LE8 scores and frailty levels in cancer survivors across the United States, thereby addressing a significant void in existing studies.MethodsThis study analyzed data from cancer survivors enrolled in the National Health and Nutrition Examination Surveys (NHANES) spanning the years 2005 to 2018, providing a comprehensive dataset. Multivariable logistic regression models were used to examine the linkage between LE8 rankings and frailty condition in cancer survivors. Furthermore, the study delved deeper into this correlation using restricted cubic spline (RCS) curves and subgroup analyses.ResultsIn the fully adjusted model, an increased LE8 level was closely associated with a reduced odds ratio of frailty among cancer survivors, with an OR of 0.95 (95% CI: 0.94–0.96, p < 0.0001).This pattern persisted across different categorizations of LE8 into low, moderate, and high groups, demonstrating a consistent trend. The analysis revealed a non-linear relationship between LE8 scores and frailty status, further supporting a straightforward association (p-value for non-linearity = 0.0729).ConclusionStudies have found that the higher the LE8 score, the less likely a cancer patient is to develop debilitating symptoms.This indicates that the LE8 scores may provide an opportunity for interventions aimed at improving the prognosis of cancer patients.

Development and assessment of an RNA editing-based risk model for the prognosis of cervical cancer patients.

RNA editing, as an epigenetic mechanism, exhibits a strong correlation with the occurrence and development of cancers. Nevertheless, few studies have been conducted to investigate the impact of RNA editing on cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC). In order to study the connection between RNA editing and CESC patients' prognoses, we obtained CESC-related information from The Cancer Genome Atlas (TCGA) database and randomly allocated the patients into the training group or testing group. An RNA editing-based risk model for CESC patients was established by Cox regression analysis and least absolute shrinkage and selection operator (LASSO). According to the median score generated by this RNA editing-based risk model, patients were categorized into subgroups with high and low risks. We further constructed the nomogram by risk scores and clinical characteristics and analyzed the impact of RNA editing levels on host gene expression levels and adenosine deaminase acting on RNA. Finally, we also compared the biological functions and pathways of differentially expressed genes (DEGs) between different subgroups by enrichment analysis. In this risk model, we screened out 6 RNA editing sites with significant prognostic value. The constructed nomogram performed well in forecasting patients' prognoses. Furthermore, the level of RNA editing at the prognostic site exhibited a strong correlation with host gene expression. In the high-risk subgroup, we observed multiple biological functions and pathways associated with immune response, cell proliferation, and tumor progression. This study establishes an RNA editing-based risk model that helps forecast patients' prognoses and offers a new understanding of the underlying mechanism of RNA editing in CESC.

Pan-cancer analysis of LRRC59 with a focus on prognostic and immunological roles in hepatocellular carcinoma.

LRRC59 is a leucine-rich repeats-containing protein located in the endoplasmic reticulum (ER), it serves as a prognostic marker in several cancers. However, there has been no systematic analysis of its role in the tumor immune microenvironment, nor its predictive value of prognosis and immunotherapy response in different cancers. A comprehensive pan-cancer analysis of LRRC59 was conducted from various databases to elucidate the associations between its expression and the prognosis of cancer, genetic alterations, tumor metabolism, and tumor immunity. Additionally, further functional assays were performed in hepatocellular carcinoma (HCC) to study its biological role in regulating cell proliferation, migration, apoptosis, cell cycle arrest, and sensitivity to immunotherapy. The pan-cancer analysis reveals a significant upregulation of LRRC59 in pan-cancer, and its overexpression is correlated with unfavorable prognosis in cancer patients. LRRC59 is negatively correlated with immune cell infiltration, tumor purity estimation, and immune checkpoint genes. Finally, the validation in HCC demonstrates LRRC59 is significantly overexpressed in cancer tissue and cell lines, and its knockdown inhibits cell proliferation and migration, promotes cell apoptosis, induces cell cycle arrest, and enhances the sensitivity to immunotherapy in HCC cells. LRRC59 emerges as a novel potential prognostic biomarker across malignancies, offering promise for anti-cancer drugs and immunotherapy.

Elucidating the impact of parthanatos-related microRNAs on the tumoral immune microenvironment and clinical outcome in low-grade gliomas

Parthanatos, a cell death mechanism triggered by PARP-1 activation, is implicated in oncogenic processes, yet their role in low-grade gliomas (LGG) remains poorly understood. This research investigates Parthanatos-related miRNAs' prognostic and immunomodulatory potential, alongside their influence on therapeutic outcomes in LGGs. Comprehensive miRNA and mRNA profiles of LGG patients were extracted from TCGA and CGGA databases, integrating clinical parameters to identify Parthanatos-associated miRNAs. IHC data validated the expression levels of Parthanatos-related genes in glioma versus normal brain tissues. Protein–protein interaction networks and Spearman correlation analysis facilitated the identification of key miRNAs. Parthanatos-related miRNA indices (PMI) were screened using Lasso and assessed for their accuracy in predicting prognosis, comparing their associated potential molecular functions and heterogeneity of the immune microenvironment. Drug sensitivity was assessed between different groups and optimal therapeutic agents were predicted. Validate the expression levels of key miRNAs by qPCR. Ninety-one miRNAs significantly associated with Parthanatos were screened, through which a PMI prognosis model of nine miRNAs was constructed. The PMI score was able to independently predict the prognosis of patients with LGG, and the nomogram constructed based on the PMI provided a practical tool for clinical prediction of patient prognosis. The proportion of immune response was lower in patients in the high-risk group, and there were significant differences in drug sensitivity between different risk classes, while drugs such as Fasudil were identified as the most promising therapeutic agents for patients in the high-risk group. Our findings highlight the critical role of Parthanatos-associated miRNAs in the progression and treatment of LGG, offering novel insights into their prognostic value and therapeutic potential.

Efficacy of surgical treatment of perianal infection in patients with hematological malignancy.

The efficacy of surgical intervention for perianal infection in patients with hematologic malignancies is not well established. Therefore, our study aimed to investigate the clinical efficacy and complications of surgical treatment of perianal infection in patients with hematologic malignancies. This retrospective study included patients with hematological malignancies who were diagnosed with perianal infections and treated at the China Aerospace Science & Industry Corporation 731 Hospital between 2018 and 2022. Patient characteristics, hematological data, surgical intervention, and complications, including recurrence and mortality, were analyzed. This study included 156 patients with leukemia aged 2 months to 71 years who were treated surgically for perianal infection, comprising 94 males and 62 females. Perianal infection included 36 cases of abscesses, 91 anal fistulas, and 29 anal fissures accompanied by infection. A total of 36 patients developed severe complications postoperatively, including 4 patients who died, 6 patients with severe incision bleeding, 18 patients with severe pain, 6 patients with sepsis, 12 patients who needed reoperation, 15 patients with hospitalization for more than 2 weeks, and 3 patients with anal stenosis; none of the patients developed anal incontinence. Additionally, risk factors for postoperative complications of perianal infection in patients with hematologic malignancies include leukopenia, agranulocytosis, thrombocytopenia, depth of abscess and not undergone an MRI. Surgical intervention may improve the prognosis of patients with perianal abscess formation, particularly in patients who show no improvement with medical therapy and those who develop perianal sepsis. Granulocytopenia and thrombocytopenia should be improved before surgery, which can significantly reduce postoperative complications. Although these findings are from a case series without a comparator, they may be of value to physicians because to the best of our knowledge, no randomized or prospective studies have been conducted on the management of perianal infections in patients with hematological malignancies.

Hypoxia-inducible factor in breast cancer: role and target for breast cancer treatment

Globally, breast cancer stands as the most prevalent form of cancer among women. The tumor microenvironment of breast cancer often exhibits hypoxia. Hypoxia-inducible factor 1-alpha, a transcription factor, is found to be overexpressed and activated in breast cancer, playing a pivotal role in the anoxic microenvironment by mediating a series of reactions. Hypoxia-inducible factor 1-alpha is involved in regulating downstream pathways and target genes, which are crucial in hypoxic conditions, including glycolysis, angiogenesis, and metastasis. These processes significantly contribute to breast cancer progression by managing cancer-related activities linked to tumor invasion, metastasis, immune evasion, and drug resistance, resulting in poor prognosis for patients. Consequently, there is a significant interest in Hypoxia-inducible factor 1-alpha as a potential target for cancer therapy. Presently, research on drugs targeting Hypoxia-inducible factor 1-alpha is predominantly in the preclinical phase, highlighting the need for an in-depth understanding of HIF-1α and its regulatory pathway. It is anticipated that the future will see the introduction of effective HIF-1α inhibitors into clinical trials, offering new hope for breast cancer patients. Therefore, this review focuses on the structure and function of HIF-1α, its role in advancing breast cancer, and strategies to combat HIF-1α-dependent drug resistance, underlining its therapeutic potential.

Acquired Fanconi syndrome in mixed cryoglobulinemia patients: a single-center case series.

Cryoglobulinemia is a pathological condition characterized by the presence of cryoglobulins in the blood, with cryoglobulinemic glomerulonephritis being the most frequent form of renal involvement. Fanconi syndrome presents as a generalized dysfunction of the proximal tubule, characterized by the presence of polyuria, phosphaturia, glycosuria, proteinuria, proximal renal tubular acidosis, and osteomalacia. We aimed to present five cases co-occurring with Fanconi syndrome and cryoglobulinemia. We retrospectively summarized the cases of five patients with Fanconi syndrome and cryoglobulinemia at Peking Union Medical College Hospital from January 2012 to June 2022. The clinical features, diagnosis, treatment, and prognosis were systematically analyzed. All five patients exhibited typical features of Fanconi syndrome, and cryoglobulinemia was concurrently detected in all cases. These patients also exhibit positive anti-nuclear antibody spectrum and hyperglobulinemia, and IgM constitutes the predominant monoclonal component in cryoglobulins. In addition to supplemental treatment, timely immunosuppressive therapy may potentially benefit the long-term renal prognosis of patients with this condition. Our findings highlight the rare co-occurrence of Fanconi syndrome and cryoglobulinemia in clinical practice. Despite the lack of causal evidence, the coexistence of Fanconi syndrome and tubulointerstitial injury is also noteworthy in patients with cryoglobulinemia, underscoring the importance of thorough evaluation and tailored management in patients presenting with overlapping renal manifestations. Key Points • Patients with mixed cryoglobulinemia can clinically present with tubulointerstitial injury, specifically manifesting as Fanconi syndrome. • In addition to typical symptoms of Fanconi syndrome, these patients also exhibit positive anti-nuclear antibody spectrum and hyperglobulinemia, while IgM constitutes the monoclonal component in cryoglobulins. • Timely immunosuppressive therapy may improve long-term renal prognosis in these patients.

Effect of a comprehensive geriatric assessment-based individualized intervention on postoperative patients with cerebral hemorrhage: A randomized controlled study.

Comprehensive geriatric assessment (CGA) has been used in inpatient, outpatient, and emergency patients in Western countries and is an important evaluation tool in medicine. In China, the application of CGA to multiple single diseases has achieved satisfactory intervention effects. To explore the effect of CGA on postoperative quality of life (QoL), psychological state, neurological recovery, and self-efficacy in patients with cerebral hemorrhage. In this randomized controlled trial, a total of 133 postoperative patients with cerebral hemorrhage who were treated and nursed in our hospital between March 2019 and March 2021 were randomly assigned to a control group (68 patients) and an observation group (65 patients). The control group was given a general comprehensive care intervention. The observation group was evaluated using an electronic medical record-based CGA system that assessed patient prognosis and was given individualized interventions based on the CGA findings. The postoperative QoL, psychological state, neurological recovery, and self-efficacy of the two groups were compared. After the intervention, self-decompression, self-decision-making, and positive attitudes of the observation group were higher than those of the control group. However, the National Institute of Health Stroke Scale score of the observation group was lower than that of the control group, the Self-rating anxiety scale and self-rating depression scale scores of the observation group were lower than those of the control group, and the social support score was significantly higher in the observation group than in the control group. After the intervention, the mental vitality, social interaction, emotional restriction, and mental status scores of the observation group were significantly higher than those of the control group. Comprehensive evaluation of patients with cerebral hemorrhage based on a CGA, targeting the individual factors that affect the prognosis of patients, and formulating and implementing individualized nursing intervention programs based on the CGA results can effectively relieve the symptoms of cerebral hemorrhage, reduce anxiety and depression, and improve the QoL of patients with cerebral hemorrhage.

Does IPSS-R down-staging before transplantation improve the prognosis of patients with Myelodysplastic Neoplasms?

In MDS patients higher IPSS-R at transplant is associated with worse transplant outcome. Thus, it may seem beneficial to improve IPSS-R by therapeutic intervention prior to transplantation in order to “down-stage” the disease risk. However, there is no evidence to date to support this approach. A retrospective analysis of the EBMT transplant registry was performed to investigate the role of therapeutic interventions prior to transplantation with regard to changes in IPSS-R and transplant outcomes. A total of 1482 MDS patients with sufficient data to calculate IPSS-R at diagnosis and at time of transplantation were selected and analysed for transplant outcome in a multivariable Cox model including IPSS-R at diagnosis, treatment intervention, change in IPSS-R before transplant and several patient and transplant variables.Transplant outcome was unaffected by IPSS-R change in untreated patients and moderately superior in chemotherapy-treated patients with improved IPSS-R at transplant. Improved IPSS-R after hypomethylating agents (HMA) or other therapies showed no beneficial effect. However, when IPSS-R progressed after chemotherapy, (HMA) or other therapies, transplant outcome was worse than without any prior treatment. Similar results were found when reduction or increase in bone marrow (BM) blasts between diagnosis and transplantation was considered. The results show a limited benefit of IPSS-R down staging or reduction of BM blasts after chemotherapy and no benefit for HMA or other treatments and thus question the role of prior therapy in MDS patients scheduled for transplantation. The model-based survival estimates should help inform decision making for both doctors and patients.

Outcomes of patients in nasopharyngeal adenoid cystic carcinoma in the IMRT era: a single-center experience

ObjectiveNasopharyngeal adenoid cystic carcinoma (NACC) is a rare malignancy with special biological features. Controversies exist regarding the treatment approach and prognostic factors in the IMRT era. This study aimed to evaluate the long-term outcomes and management approaches in NACC.MethodsFifty patients with NACC at our institution between 2010 and 2020 were reviewed. Sixteen patients received primary radiotherapy (RT), and 34 patients underwent primary surgery.ResultsBetween January 2010 and October 2020, a total of 50 patients with pathologically proven NACC were included in our analysis. The median follow-up time was 58.5 months (range: 6.0–151.0 months). The 5-year overall survival rate (OS) and progression-free survival rate (PFS) were 83.9% and 67.5%, respectively. The 5-year OS rates of patients whose primary treatment was surgery and RT were 90.0% and 67.3%, respectively (log-rank P = 0.028). The 5-year PFS rates of patients whose primary treatment was surgery or RT were 80.8% and 40.7%, respectively (log-rank P = 0.024). Multivariate analyses showed that nerve invasion and the pattern of primary treatment were independent factors associated with PFS.ConclusionsDue to the relative insensitivity to radiation, primary surgery seemed to provide a better chance of disease control and improved survival in NACC. Meanwhile, postoperative radiotherapy should be performed for advanced stage or residual tumours. Cranial nerve invasion and treatment pattern might be important factors affecting the prognosis of patients with NACC.

MULTIPLE RESIDUAL ROOTS EXTRACTIONS AND ETIOPATHOGENESIS OF ASSOCIATED PERIAPICAL LESION: A SURGICAL CASE REPORT

Before any surgical intervention in dentistry, it is necessary to plan each case correctly, to induce a positive prognosis for patients, always enabling the functionality of the stomatognathic system. Men tend to have more teeth extracted than women, with more posterior teeth extracted in patients in more advanced age groups due to periodontal disease. The case presented leads to a discussion of the periapical lesions removed surgically. The etiology and study of the evolutionary process of pulp pathology and the supporting tissues of the dental element are substantial. The endo-periodontal interrelationship is unique and can be considered a single continuous system or biological unit with multiple forms of communication. In summary, this article seeks to highlight and report a surgical case of a patient diagnosed with periapical lesions associated with residual tooth roots, which were removed during the common exodontia protocol with the aim of total rehabilitation of the patient. The patient authorized all the images and information used in this study.

PCDHGA10 as a Potential Biomarker of Lung Squamous Cell Carcinoma Based on Bioinformatics and Experimental Verification.

Procalcitonin gamma subfamily A, 10 (PCDHGA10) is a member of the procalcitonin gamma gene cluster, which is associated with neuronal synapse development. However, there are lack of studies on the role and potential prognostic value of PCDHGA10 in lung squamous cell carcinoma (LUSC). We analyzed the RNAseq data of PCDHGA10 to compare their expression differences. Then survival analysis, tumor microenvironment (TME) analysis, and mutation analysis were carried out. Additionally, we performed gene ontology (GO) and kyoto gene encyclopedia (KEGG) enrichment analyses to explore potential signal pathways. PCDHGA10 protein expression was evaluated using immunohistochemistry (IHC) on tissue microarrays (HLugS180Su02). By microarray analysis and database analysis, we found that PCDHGA10 was significantly highly expressed in LUSC. Sufferers with elevated PCDHGA10 levels exhibited a worse prognosis, according to the survival analysis. The PCDHGA10 mutation was also linked to LUSC patient prognosis. Besides, PCDHGA10 was closely related to tumor immune cell infiltration andimmunecheckpoints. In conclusion, PCDHGA10 is expected to become a new molecular marker for LUSC.

Analysis of onset-to-door time and its influencing factors in Chinese patients with acute ischemic stroke during the 2020 COVID-19 epidemic: a preliminary, prospective, multicenter study

BackgroundPre-hospital delay in China is a serious issue with unclear relevant reasons, seriously impeding the adoption of appropriate measures. Herein, we analyzed the onset-to-door time (ODT) in Chinese patients with acute ischemic stroke (AIS) and its influencing factors.MethodsWe prospectively recruited 3,459 patients with AIS from nine representative tertiary general hospitals in China between January and June 2022. Patients were divided into ODT ≤ 3 h and ODT > 3 h groups. Following single-factor analysis, binary logistic regression analysis was performed to evaluate the risk factors leading to pre-hospital delay.ResultsIn total, 763 (21.83%) patients arrived at the hospital within 3 h of onset. After adjusting for confounding factors, the risk factors for ODT were residence in rural areas (odds ratio [OR]: 1.478, 95% credibility interval [CI]: 1.024–2.146) and hospital transfer (OR: 7.479, 95% CI: 2.548–32.337). The protective factors for ODT were location of onset ≤ 20 km from the first-visit hospital (OR: 0.355, 95% CI: 0.236–0.530), transportation by emergency medical services (OR: 0.346, 95% CI: 0.216–0.555), history of atrial fibrillation (OR: 0.375, 95% CI: 0.207–0.679), moderate stroke (OR: 0.644, 95% CI: 0.462–0.901), and severe stroke (OR: 0.506, 95% CI: 0.285–0.908).ConclusionsMost patients with AIS fail to reach a hospital within the critical 3-h window. The following measures are recommended to reduce pre-hospital delays: reasonable distribution of hospitals accessible to nearby residents, minimizing interhospital transfer, paying attention to patients with mild stroke, and encouraging patients to use ambulance services. Pre-hospital delays for patients can be reduced by implementing these measures, ultimately improving the timeliness of treatment and enhancing patient prognosis. This study was carried out amid the COVID-19 pandemic, which presented challenges and constraints.

Clinical characteristics and prognosis of patients with infective endocarditis admitted to a coronary unit in a hospital with cardiac surgery

Abstract Funding Acknowledgements None. Introduction Cardiac critical care units are essential for the management of complicated infective endocarditis (IE). Objective We set out to analyze the baseline characteristics, clinical complications and prognosis of patients with IE admitted to a Coronary Care Unit (CCU), as well as to compare them with patients admitted to hospital wards. Material and Methods Prospective, single-centre, observational study including patients who were diagnosed of IE from 2016-2022 and admitted in a hospital with cardiac surgery. They were classified into two groups according to whether or not they were admitted to the CCU. We collected data on microbiological isolation, cardiac and systemic complications as well as in-hospital mortality. Patients were followed long-term for cardiovascular (CV) and all-cause mortality, readmission and IE recurrence. All variables (qualitative) were compared by Chi-square test and overall mortality was compared in both groups by the LogRank test. We established a significance level of p&amp;lt;0.05. Results From a total of 162 patients with a median age of 68 years (IQR 68), 28.4% (46) were admitted to the CCU. These patients were similar in age to those not admitted (mean 65 vs 66 years, NS), but had a higher percentage of diabetics (47.8 vs 27.6%, p=0.01). The most frequent previous heart disease in both groups was valvular heart disease. The most frequently isolated microorganisms in CCU patients were Staphylococcus aureus (46.4%) and Streptococcus epidermidis (37.9%) which, in our series, produced the highest percentage of shock (35.7% and 23.3% respectively) in a statistically significant way (p&amp;lt;0.01), with the need for noradrenaline (60.9%) and dobutamine (28.3%); no ventricular assist devices were used. Critically ill patients had a higher incidence of atrioventricular block requiring a permanent pacemaker (32.6% vs 4.3%, p&amp;lt;0.01), valve dysfunction (76.1% vs 55.2%, p=0.014) and were more frequently operated than those admitted to the ward (56.%% vs 38%, p=0.04). Among all IE patients, 24.6% died during admission, most of them (15.7% of the total) were admitted to the coronary unit (p&amp;lt;0.01). In our 36-month mean follow-up, we found significantly higher readmission rates in the CCU group (36.6% vs. 15%, p&amp;lt;0.01), unrelated to IE recurrences. The critically ill group exhibited a higher mortality rate due to cardiovascular disease and all-cause causes (43.5% vs 15.9%, p0.01; 63% vs 23.9%, p0.01). In the CCU group there is significantly lower survival (mean 65 vs 37 months, LogRank p&amp;lt;0.01) with respect to the hospital ward group. Conclusion Our CCU is responsible for treating patients with IE that is highly complex and that progresses poorly, with a higher frequency of shock and in-hospital mortality, which leads to a decreased prognosis during follow-up. Anticipating complications and collaborating with cardiac surgery is essential to improve clinical outcomes.

High STAT4 expression correlates with poor prognosis in acute myeloid leukemia and facilitates disease progression by upregulating VEGFA expression.

The aim of our study is to explore the mechanism of transcription-4 (STAT4) in acute myeloid leukemia (AML). STAT4 level in AML bone marrow samples/cells was analyzed using bioinformatics and quantitative real-time PCR. The correlation between high STAT4 expression and the prognosis of AML patients was analyzed. The viability, apoptosis, and angiogenesis of AML cells were detected. The levels of STAT4, vascular endothelial growth factor A (VEGFA), and apoptosis-related proteins (Bcl-2 and Bax) in transfected AML cells were examined. STAT4 level was upregulated in AML. STAT4 silencing decreased the viability and angiogenesis, yet increased the apoptosis of AML cells, while overexpressed STAT4 did conversely. VEGFA silencing counteracted the impacts of overexpressed STAT4 upon promoting viability and angiogenesis as well as repressing the apoptosis of AML cells. High STAT4 expression was correlated with poor prognosis of AML patients and facilitated disease progression via upregulating VEGFA expression.

Prognosis of patients with advanced bile tract carcinoma: assessment using the modified-Gustave Roussy Immune Score (mGRIm-s) as a clinico-immunological tool

BackgroundThe emergence of immune checkpoint inhibitors (ICIs) has enhanced survival outcomes for certain patients with advanced biliary tract carcinoma (BTC). Pinpointing those who would benefit most from immunotherapy remains elusive. We investigated the predictive value of the modified Gustave Roussy Immune Score (mGRIm-s) in BTC patients treated with ICIs.MethodsData from 110 patients at Chinese People's Liberation Army General Hospital, spanning September 2015 to April 2021, were analyzed. The median follow-up duration was 38.7 months as of December 2023. Risk factors included low albumin, high lactate dehydrogenase, and an elevated neutrophil–lymphocyte ratio. Patients were stratified into low (patients with no risk factors) and high (patients with at least one risk factor) mGRIm-s groups based on these factors.ResultsSurvival outcomes post-immunotherapy favored the low mGRIm-s group, with significantly improved progression-free survival (PFS) and overall survival (OS) (8.50 months vs. 3.70 months and 21.60 months vs. 8.00 months). COX regression confirmed an elevated risk in the high mGRIm-s group. Subgroup analysis highlighted a notable survival advantage for low mGRIm-s patients receiving first-line immunotherapy.ConclusionsThis study underscores mGRIm-s's potential in predicting immunotherapy response in BTC, paving the way for more targeted approaches.

Influence of tricuspid regurgitation on the prognosis of patients with cardiogenic shock

Objective Tricuspid regurgitation (TR) is associated with adverse prognosis in various patient populations. However, data regarding the prognostic impact in patients with cardiogenic shock (CS) is limited. The study investigates the prognostic impact of pre-existing TR in patients with CS. Methods Consecutive patients with CS from 2019 to 2021 were included in a monocentric registry. Every patient's medical history, including echocardiographic data, was recorded. The influence of pre-existing TR on prognosis was investigated. Furthermore, Kaplan-Meier analyses based on TR severity were conducted. Statistical analyses comprised univariable t-test, Spearman´s correlation, Kaplan-Meier analyses, as well as multivariable Cox proportional regression models. Analyses were stratified by the underlying cause of CS such as acute myocardial infarction (AMI), or the need for mechanical ventilation. Results 105 patients with CS and pre-existing TR were included. In Kaplan Meier analyses, it could be demonstrated that patients with severe TR (TR III°) had the highest 30-day all-cause mortality compared to mild (TR I°) and moderate TR (TR II°) (44% vs. 52% vs. 77%; log rank p = 0.054). In the subgroup analyses of CS-patients without AMI, TR II°/TR III° showed a higher all-cause mortality after 30 days compared to TR I° (39% vs. 64%; log rank p = 0.027). In multivariable Cox regression TR II°/TR III° was associated with 30-day all-cause mortality in CS-patients without AMI (HR = 2.193; 95% CI 1.007–4.774; p = 0.048). No significant difference could be found in the AMI group. Furthermore, TR II°/III° was linked to an increased 30-day all-cause mortality in non-ventilated CS-patients (6% vs. 50%, log rank p = 0.005), which, however, could not be confirmed in multivariable Cox regression. Conclusion The occurrence of pre-existing TR II°/III° was independently related with 30-day all-cause mortality in CS-patients without AMI. However, no prognostic influence was observed in CS-patients with AMI.

Clinical prognostic value of different NPM1 mutations in acute myeloid leukemia patients.

Acute myeloid leukemia (AML) patients with various nucleophosmin 1 (NPM1) mutations are controversial in the prognosis. This study aimed to investigate the prognosis of patients according to types of NPM1 mutations (NPM1mut). Bone marrow samples of 528 patients newly diagnosed with AML, were collected for morphology, immunology, cytogenetics, and molecular biology examinations. Gene mutations were detected by next-generation sequencing (NGS) technology. About 25.2% of cases exhibited NPM1mut. 83.5% of cases were type A, while type B and D were respectively account for 2.3% and 3.0%. Furthermore, 15 cases of rare types were identified, of which 2 cases have not been reported. Clinical characteristics were similar between patients with A-type NPM1 mutations (NPM1A - type mut) and non-A-type NPM1 mutations (NPM1non - A-type mut). Event-free survival (EFS) was significantly different between patients with low NPM1non - A-type mut variant allele frequency (VAF) and low NPM1A - type mut VAF (median EFS = 3.9 vs. 8.5 months, P = 0.020). The median overall survival (OS) of the NPM1non - A-type mutFLT3-ITDmut group, the NPM1A - type mutFLT3-ITDmut group, the NPM1non - A-type mutFLT3-ITDwt group, and the NPM1A - type mutFLT3-ITDwt group were 3.9, 10.7, 17.3 and 18.8 months, while the median EFS of the corresponding groups was 1.4, 5.0, 7.6 and 9.2 months (P < 0.0001 and P = 0.004, respectively). No significant difference was observed in OS and EFS between patients with NPM1A - type mut and NPM1non - A-type mut. However, types of NPM1 mutations and the status of FLT3-ITD mutations may jointly have an impact on the prognosis of AML patients.

Impact of misdiagnosis on the treatment and prognosis of acute aortic syndrome

Abstract Funding Acknowledgements None. Introduction Acute aortic syndrome (AAS) embraces a spectrum of pathologies with relatively low prevalence but associated with high mortality. The clinical presentation of AAS is highly variable and the differential diagnosis with other much more common diseases such as myocardial infarction (AMI) or pulmonary embolism (PE) is often difficult to achieve. AAS detection requires a high index of suspicion and the delay in diagnosis is associated with increased morbidity and mortality. Purpose The aim of this study is to characterize the diagnostic approach to AAS patients in the emergency department (ED) and to study the impact of the initial diagnostic suspicion on the treatment and prognosis of patients with AAS. Methods The "Aorta Code" is an inter-hospital and interdisciplinary care protocol for the management of patients with AAS in a 4-Hospital network. Patients with AAS were prospectively and consecutively collected from 2019 to 2022. The sample was classified into two groups according to whether the initial suspicion was AAA or another clinical entity. The diagnosis of AAS was established by computed tomography in all patients. Time, clinical, treatment and prognostic variables were analyzed. Results A total of 113 patients with AAS were included. Of them, only 38% (34) were initially suspected of having an AAS (Figure). AMI and PE were the initial diagnosis in 34% of patients (Figure). There were no significant differences in age, history of hypertension or other cardiovascular risk factors between the groups (table). Anterior chest pain was more frequent in the "AAS-suspicion" group. The diagnostic time delay was longer in patients with initial misdiagnosis (table). Patients with type A AAS with initial misdiagnosis underwent surgery in a lower proportion (table). Although the differences were not significant, patients with initial misdiagnosis had more postoperative complications and higher mortality. Conclusion It is essential to maintain a high index of diagnostic suspicion for AAS in the ED. Initial misdiagnosis is associated with a delayed diagnosis, delayed surgical treatment and a lower rate of surgery. In addition, although it is a small sample size, this group of patients had more postoperative complications and higher mortality.
