Association between hs-CRP/HDL-C ratio and three-month unfavorable outcomes in patients with acute ischemic stroke: a second analysis based on a prospective cohort study

ObjectiveThe associations between the ratio of blood high-sensitivity C-reactive protein (hs-CRP) to high-density lipoprotein cholesterol (HDL-C) (hs-CRP/HDL-C ratio) and outcomes in patients with acute ischemic stroke (AIS) have yet to be established. This study is the first to examine the relationship between the hs-CRP/HDL-C ratio and three-month unfavorable outcomes in patients with AIS.MethodsThis secondary analysis utilized data from a prospective cohort study involving 1559 AIS patients recruited at a South Korean hospital between January 2010 and December 2016. We constructed a binary logistic regression model to explore the association between the hs-CRP/HDL-C ratio and unfavorable outcomes in patients with AIS. An attempt was made to use a generalized additive model (GAM) with smooth curve fitting to elucidate potential nonlinear interactions. Furthermore, inflection points were identified via a recursive method, and binary logistic regression models were developed for each side of these inflection points. Ultimately, a log-likelihood ratio test was used to identify the most appropriate model for explaining the connection between the hs-CRP/HDL-C ratio and unfavorable outcomes in patients with AIS.ResultsThe incidence of unfavorable outcomes was 24.5%, with a median hs-CRP/HDL-C ratio of 3.64. After accounting for other factors, the binary logistic regression model revealed a statistically significant positive association between the hs-CRP/HDL-C ratio and the likelihood of poor outcomes in AIS patients (OR = 1.013, 95% CI: 1.005–1.022; P = 0.002). A nonlinear relationship was observed, with the first inflection point of the hs-CRP/HDL-C ratio at 42.74. Each 1-unit increase in the hs-CRP/HDL-C ratio was associated with a 2.4% greater risk of unfavorable outcomes (OR = 1.024, 95% CI: 1.011–1.038, P < 0.001).ConclusionThis study provides evidence of a positive and nonlinear correlation between the hs-CRP/HDL-C ratio and poor three-month functional outcomes in AIS patients. When the hs-CRP/HDL-C ratio was less than 42.74, a positive association was observed with the risk of unfavorable outcomes. This finding offers a reference for optimizing early individualized therapy and aids in clinical counseling for patients with AIS.

Refining risk stratification in hypertrophic cardiomyopathy: the role of late gadolinium enhancement and syncope in predicting adverse outcomes

Abstract Background The presence of late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging (MRI) is recognized as a significant marker of myocardial fibrosis and a predictor of adverse outcomes in hypertrophic cardiomyopathy (HCM). Nevertheless, the specific quantity of LGE that correlates with poor outcomes is still under debate. Therefore, this study sought to assess the combined impact of LGE presence and a history of syncopal events and its association with clinical prognosis. Methods Between May 2018 and June 2023, a total of 230 HCM patients was prospectively enrolled at our Medical University, a tertiary referral center. The primary endpoint was a composite of new-onset ventricular tachycardia (VT), appropriate ICD therapy, and all-cause mortality. Results Median age of enrolled patients was 56 (IQR 44-64) years and 40% (n=94) were female. Median interventricular septal thickness (IVS) was 21 (IQR 18–25) mm and 43 % (n=84) had significant left ventricular outflow tract obstruction (LVOTO). Over a median follow-up of 3.2 years, 30 patients (13%) met the composite endpoint. These patients had a significantly higher LGE quantity compared to the non-event group (1.1 % vs. % 9.0, P=0.012). An LGE threshold of 5.2% was identified as an optimal predictor of the composite endpoint, with an area under the curve of 0.72, which increased to 0.77 when including at least one syncopal event in medical history. LGE &amp;gt; 5.2% and/or syncope were independently associated with adverse outcomes after multivariable adjustment (Adj HR 7.26 [95%CI 2.54-20.72]). Furthermore, NTproBNP and hsTnT were associated with the presence of LGE or syncope (OR for a 1-unit increase in standardized log-transformed biomarker NTproBNP 3.35 [95%CI 1.42-10.85]; hsTnT 3.48 [95%CI 1.48-10.24], respectively). Interestingly, typically used variables for risk stratification, such as age, IVS or LVOT were not significantly associated with these cardiac biomarkers. Conclusion An extent of LGE &amp;gt; 5.2% and the history of at least one syncope are associated with unfavorable clinical outcomes in HCM patients. These findings call for detailed MRI appraisal and suggest adopting a holistic approach to accurately identify high-risk patients.

Effect of Statins and Renin–Angiotensin–Aldosterone System Inhibitors on IL-6 Levels in COVID-19 Patients

Background/Objectives: Severe clinical course and mortality from COVID-19 are mostly associated with increased concentrations of IL-6 and IL-10. Findings from clinical trials suggest that both statins and renin–angiotensin–aldosterone system inhibitors (RAASI) might have the potential to reduce unfavorable outcomes in patients with COVID-19. The aim of this study was to evaluate the effect of statins and RAASI on the cytokine concentrations in COVID-19 patients. Methods: SARS-CoV-2 infected patients were enrolled in this study, and demographic, clinical, and routine laboratory data were evaluated. Plasma cytokine levels were measured by multiplex assay. Results: COVID-19 patients with chronic cardiovascular diseases (CVD) had significantly lower median plasma IL-6 levels than COVID-19 patients with no co-morbidities (26 vs. 53 pg/mL, p = 0.021). COVID-19 patients with CVD who were taking statins had significantly lower median concentrations of IL-6 (21 vs. 44 pg/mL, p = 0.027), TNFα (21 vs. 39.5 pg/mL, p = 0.036), and IL-10 (19 vs. 25.5 pg/mL, p = 0.025) compared to COVID-19 patients with no CVD. In a binary logistic regression model, IL-6 was a significant variable, with an odds ratio value of 0.961 (95% CI 0.929–0.995). Regarding RAASI, only plasma IL-6 (22 vs. 44 pg/mL, p = 0.012) levels were found to be significantly lower in COVID-19 patients with CVD consuming these medications compared to patients who did not have any CVD. Conclusions: COVID-19 patients who had chronic cardiovascular co-morbidities and who were administered statins or RAASI had significantly lower concentrations of IL-6 than COVID-19 patients who did not have any co-morbidities. These findings suggest that the use of statins or RAASI may be of value in COVID-19 patients.

SEMA7A-mediated juxtacrine stimulation of IGFBP-3 upregulates IL-17RB at pancreatic cancer invasive front.

Tumor invasion is the hallmark of tumor malignancy. The invasive infiltration pattern of tumor cells located at the leading edge is highly correlated with metastasis and unfavorable patient outcomes. However, the regulatory mechanisms governing tumor malignancy at the invasive margin remain unclear. The IL-17B/IL-17RB pathway is known to promote pancreatic cancer invasion and metastasis, yet the specific mechanisms underlying IL-17RB upregulation during invasion are poorly understood. In this study, we unveiled a multistep process for IL-17RB upregulation at the invasive margin, which occurs through direct communication between tumor cells and fibroblasts. Tumor ATP1A1 facilitates plasma membrane expression of SEMA7A, which binds to and induces IGFBP-3 secretion from fibroblasts. The resulting gradient of IGFBP-3 influences the direction and enhances IL-17RB expression to regulate SNAI2 in invasion. These findings highlight the importance of local tumor-fibroblast interactions in promoting cancer cell invasiveness, potentially leading to the development of new therapeutic strategies targeting this communication.

Results of surgical treatment for drug-resistant temporal epilepsy and related predictors of negative post-surgery outcome

Objective: to evaluate the results of surgical treatment and identify related predictors of unfavorable outcome in patients with temporal drug-resistant epilepsy (DRE) in long-term postoperative period.Material and methods. Fifty-one patients with temporal lobe DRE were examined using clinical, neuroimaging, electro- physiological, and laboratory research methods from June 2020 to June 2023. Anteromedial temporal lobectomy (AMLE) and selective amygdalohippocampectomy (SAHE) were performed in 38 (74.5%) and 13 (25.5%) cases, respectively. Postsurgery outcomes were evaluated in 51 patients 6 months later, continued in 43 and 20 patients 1 year and 2 years, respectively, afterwards.Results. The percentage of patients with significant improvement (Engel I/II) 6 months, 1 year and 2 years post-surgery was 82.4%, 72.1%, and 55.0%, respectively. After AMLE vs. SAHE, patients had a more favorable outcome while assessing seizure control. The predictors of unfavorable post-surgery outcome included a prolonged epilepsy course before surgery, the presence of electroencephalography-verified epileptiform activity in postoperative period, and repeated surgical intervention. Patient age, the presence of focal seizures evolving into bilateral tonic-clonic seizures as well as more frequent seizures before surgery were considered as potential predictors.Conclusion. The study results show that quite high effectiveness of seizure control in postoperative period in temporal DRE is quite high that may be accounted for by probability of removing epileptogenic foci and suppression of the mechanisms ensuring emergence and irritation of epileptic discharges. Nevertheless, effectiveness of surgical treatment fades off with time, which requires to further investigate the negative factors countering long-term post-surgery effect. In connection with this, a special attention should be paid to factors such as the presence of electroencephalography-verified epileptiform activity in postoperative period, repeated surgical intervention as well as prolonged epilepsy before surgery.

Brain-targeted ursolic acid nanoparticles for anti-ferroptosis therapy in subarachnoid hemorrhage

BackgroundSubarachnoid hemorrhage (SAH) is a life -threatening cerebrovascular disease, where early brain injury (EBI) stands as a primary contributor to mortality and unfavorable patient outcomes. Neuronal ferroptosis emerges as a key pathological mechanism underlying EBI in SAH. Targeting ferroptosis for therapeutic intervention in SAH holds significant promise as a treatment strategy.MethodsSAH model was induced via intravascular puncture and quantitatively assessed the presence of neuronal ferroptosis in the early phase of SAH using FJC staining, Prussian blue staining, as well as malondialdehyde (MDA) and glutathione (GSH) measurements. Hyaluronic acid-coated ursolic acid nanoparticles (HA-PEG-UA NPs) were prepared using the solvent evaporation method. We investigated the in vivo distribution of HA-PEG-UA NPs in SAH model through IVIS and fluorescence observation, and examined their impact on short-term neurological function and cortical neurological injury. Finally, we assessed the effect of UA on the Nrf-2/SLC7A11/GPX4 axis via Western Blot analysis.ResultsWe successfully developed self-assembled UA NPs with hyaluronic acid to target the increased CD44 expression in the SAH-afflicted brain. The resulting HA-PEG-UA NPs facilitated delivery and enrichment of UA within the SAH-affected region. The targeted delivery of UA to the SAH region can effectively inhibit neuronal ferroptosis, improve neurological deficits, and prognosis in mice. Its mechanism of action is associated with the activation of the Nrf-2/SLC7A11/GPX4 signaling pathway.ConclusionsBrain-targeted HA-PEG-UA NPs was successfully developed and hold the potential to enhance SAH prognosis by limiting neuronal ferroptosis via modulation of the Nrf-2/SLC7A11/GPX4 signal.Graphical

Nano Spirulina platensis countered cisplatin-induced repro-toxicity by reversing the expression of altered steroid hormones and downregulation of the StAR gene.

Cisplatin is a commonly utilized chemotherapy medication for treating different sarcomas and carcinomas. Its ability interferes with cancer cells' DNA repair pathways and postpones unfavorable outcomes in cancer patients. The current investigation's goal was to ascertain if nano Spirulina platensis (NSP) might shield rat testicles from cisplatin damage by assessing the expression of the StAR and SOD genes, sex hormones, 17ß-hydroxysteroid dehydrogenase(17ß-HSD), sperm profile picture, oxidative condition of testes, testicular histology, and DNA damage. Four equal and random groups of 28 adult male Wistar rats were created; the control group was given saline for 8weeks. An extraction of NSP at a concentration of 2500mg/kg body weight was administered orally for 8weeks to the NSP group. For the first 4weeks, the cisplatin group was intraperitoneally injected with 2mg/kg/body weight of cisplatin, and for the next 4weeks, they were given a dosage of 4mg/kg/body weight. The cisplatin + NSP group was given both NSP and cisplatin. The results of the experiment showed that intake of NSP and cisplatin improved sperm profile; re-established the balance of oxidizing agents and antioxidant state; enhanced testicular histology; promoted the histometric parameters of seminiferous tubules including epithelial height, their diameter, and Johnsen's score, decreasing DNA breakage in testicular tissue; increased testosterone level; decreased 17ß-HSD concentration; and upregulated both the StAR and SOD gene expression in testicles compared to rats exposed to cisplatin alone. These results demonstrate that NSP is a promising agent for improving cisplatin-induced testicular injury and infertility.

Liberalization of the Systemic Glucose Management is Associated with a Reduced Frequency of Neuroglucopenia in Subarachnoid Hemorrhage Patients: An Observational Cohort Study.

Pathologically low brain glucose levels, referred to as neuroglucopenia, are associated with unfavorable outcomes in neurocritical care patients. We sought to investigate whether an increase in serum glucose levels would be associated with a reduction of neuroglucopenia. In this retrospective analysis of prospectively collected data, we included 55 consecutive patients with spontaneous subarachnoid hemorrhage who underwent cerebral microdialysis (CMD) monitoring. Neuroglucopenia was defined as CMD-glucose levels < 0.7mmol/l. We identified systemic glucose liberalization events, defined as a day with median serum glucose levels < 150mg/dl, followed by a day with median serum glucose levels > 150mg/dl, and compared concentrations of cerebral metabolites between these days. Unfavorable outcome was defined as modified Rankin Scale score ≥ 3 at 3 months after the bleeding. Episodes of neuroglucopenia were more frequent in patients with unfavorable outcome (19.8% [19.3-20.3%] vs. 10.9% [10.4-11.5%], p = 0.007). Sixty-nine systemic glucose liberalization events were identified in 40 patients. Blood glucose levels increased from 141.2 (138.7-143.6) mg/dl to 159.5 (157.0-162.2) mg/dl (p < 0.001), CMD-glucose levels increased from 1.44 (1.39-1.50) mmol/l to 1.68 (1.62-1.75) mmol/l (p = 0.001), and the frequency of neuroglucopenia decreased from 24.7% (22.9-26.5%) to 20.2% (18.7-21.8%) (p = 0.002) during these events. Liberalization was not associated with changes in CMD-lactate, CMD-pyruvate, CMD-lactate-to-pyruvate ratio, CMD-glutamate, or CMD-glycerol. In conclusion, the liberalization of serum glucose concentrations to levels between 150 and 180 mg/dl was associated with a significant reduction of neuroglucopenia.

Elucidating the power of arginine restriction: taming type I interferon response in breast cancer via selective autophagy

BackgroundType I interferons (IFN-I) are potent alarm factors that initiate cancer cell elimination within tumors by the immune system. This critical immune response is often suppressed in aggressive tumors, thereby facilitating cancer immune escape and unfavorable patient outcome. The mechanisms underpinning IFN-I suppression in tumors are incompletely understood. Arginase-1 (ARG1)-expressing immune cells that infiltrate tumors can restrict arginine availability by ARG1-mediated arginine degradation. We hypothesized that arginine restriction suppresses the IFN-I response in tumors.MethodsComprehensive, unbiased open approach omics analyses, various in vitro techniques, including microscopy, qPCR, immunoblotting, knock-down experiments, and flow cytometry were employed, as well as ex vivo analysis of tumor tissue from mice. Several functional bioassays were utilized to assess metabolic functions and autophagy activity in cancer cells.ResultsArginine restriction potently induced expression of selective autophagy receptors, enhanced bulk and selective autophagy and strongly suppressed the IFN-I response in cancer cells in an autophagy-dependent manner.ConclusionOur study proposes a mechanism for how tumor-infiltrating immune cells can promote cancer immune escape by dampening the IFN-I response. We suggest ARG1 and autophagy as putative therapeutic targets to activate the IFN-I response in tumors.

Transcription factor EB (TFEB) promotes autophagy in early brain injury after subarachnoid hemorrhage in rats.

Subarachnoid hemorrhage (SAH) has high mortality. Early brain injury (EBI) is responsible for unfavorable outcomes for patients with SAH. The protective involvement of autophagy in hemorrhagic stroke has been proposed. The transcription factor EB (TFEB) can increase autophagic flux by promoting autophagosome formation and autophagosome-lysosome fusion, and dysregulation of TFEB activity might induce the development of several diseases. However, the biological functions of TFEB in EBI after SAH remain unknown. We established an animal model of SAH by the modified endovascular perforation method. Expression of TFEB and autophagy required genes was measured by western blotting and immunofluorescence staining. SAH grading, brain water content and neurobehavioral functions were evaluated at 24h post-SAH. Neuronal apoptosis in cerebral cortex was assessed by TUNEL staining and Fluoro Jade B staining. TFEB was downregulated in SAH rats, and its overexpression reduced brain edema and ameliorated neurological deficits of SAH rats. Additionally, the neuronal apoptosis induced by SAH was inhibited by TFEB overexpression. Moreover, TFEB overexpression promoted autophagy after SAH. TFEB overexpression promotes autophagy to inhibit neuronal apoptosis, brain edema and neurological deficits post-SAH.

The association between serum S100β levels and prognosis in acute stroke patients after intravenous thrombolysis: a multicenter prospective cohort study

BackgroundS100β is a biomarker of astroglial damage, the level of which is significantly increased following brain injury. However, the characteristics of S100β and its association with prognosis in patients with acute ischemic stroke following intravenous thrombolysis (IVT) remain unclear.MethodsPatients in this multicenter prospective cohort study were prospectively and consecutively recruited from 16 centers. Serum S100β levels were measured 24 h after IVT. National Institutes of Health Stroke Scale (NIHSS) and hemorrhagic transformation (HT) were measured simultaneously. NIHSS at 7 days after stroke, final infarct volume, and modified Rankin Scale (mRS) scores at 90 days were also collected. An mRS score ≥ 2 at 90 days was defined as an unfavorable outcome.ResultsA total of 1072 patients were included in the analysis. The highest S100β levels (> 0.20 ng/mL) correlated independently with HT and higher NIHSS at 24 h, higher NIHSS at 7 days, larger final infarct volume, and unfavorable outcome at 3 months. The patients were divided into two groups based on dominant and non-dominant stroke hemispheres. The highest S100β level was similarly associated with the infarct volume in patients with stroke in either hemisphere (dominant: β 36.853, 95% confidence interval (CI) 22.659–51.048, P < 0.001; non-dominant: β 23.645, 95% CI 10.774–36.516, P = 0.007). However, serum S100β levels at 24 h were more strongly associated with NIHSS scores at 24 h and 3-month unfavorable outcome in patients with dominant hemisphere stroke (NIHSS: β 3.470, 95% CI 2.392–4.548, P < 0.001; 3-month outcome: odds ratio (OR) 5.436, 95% CI 2.936–10.064, P < 0.001) than in those with non-dominant hemisphere stroke (NIHSS: β 0.326, 95% CI − 0.735–1.387, P = 0.547; 3-month outcome: OR 0.882, 95% CI 0.538–1.445, P = 0.619). The association of S100β levels and HT was not significant in either stroke lateralization group.ConclusionsSerum S100β levels 24 h after IVT were independently associated with HT, infarct volume, and prognosis in patients with IVT, which suggests the application value of serum S100β in judging the degree of disease and predicting prognosis.

Association of dynamic changes in arterial partial pressure of carbon dioxide with neurological outcomes in aneurysmal subarachnoid hemorrhage

BackgroundCerebral blood flow (CBF) is closely regulated by carbon dioxide (CO2). In patients with aneurysmal subarachnoid hemorrhage (aSAH), abnormal arterial partial pressure of CO2 (PaCO2) might deteriorate brain injuries. Nevertheless, the impact of dynamic PaCO2 fluctuations on neurological outcomes in aSAH patients has not been extensively studied. Our study aimed to investigate the association between dynamic PaCO2 levels and unfavorable neurological outcomes in aSAH patients. MethodsIn this retrospective observational study, we consecutively enrolled 159 aSAH patients from December 2019 to July 2021. Arterial blood gas measurements within 10 days after intensive care unit (ICU) admission for each patient were recorded to calculate the time-weighted average (TWA)-PaCO2, an indicator representing the dynamic changes in PaCO2 levels. For the association between TWA-PaCO2 levels and unfavorable neurological outcomes in aSAH patients, multivariable logistic analysis was used to explore TWA-PaCO2 levels as categorical variables, and restricted cubic spline (RCS) was used to explore TWA-PaCO2 levels as continuous variables. ResultsIn multivariable logistic analysis, after adjusting confounders, when TWA-PaCO2 35–45 mmHg was as a reference, TWA-PaCO2 < 35 mmHg (odds ratio [OR] 2.15, 95 % confidence interval [CI] 0.83–5.55, P = 0.113) and TWA-PaCO2 > 45 mmHg (OR 8.31, 95 % CI 0.72–96.14, P = 0.090) were not independently associated with unfavorable neurological outcomes (modified Rankin score of 3–6). The RCS shows a “U” shape curve between TWA-PaCO2 levels and unfavorable neurological outcomes, with a nonlinear P-value of 0.023. The lowest ORs of unfavorable neurological outcomes were within PaCO2 32.8–38.1 mmHg. ConclusionsBoth lower and higher PaCO2 levels are harmful to aSAH patients. PaCO2 in the range of 32.8–38.1 mmHg is associated with lowest unfavorable neurological outcomes.

ARL8B promotes hepatocellular carcinoma progression and inhibits antitumor activity of lenvatinib via MAPK/ERK signaling by interacting with RAB2A

Tumor recurrence and metastasis are important factors affecting postoperative survival in hepatocellular carcinoma (HCC) patients. ADP Ribosylation factor-like GTPase 8B (ARL8B) plays a crucial role in many biological processes, including lysosomal function, immune response, and cellular communication, all of which are related to the occurrence and development of tumors. However, its role in HCC remains unclear. Herein, we revealed that ARL8B is consistently elevated in HCC tissues compared to normal liver tissues, suggesting an unfavorable outcome in HCC patients. Increased ARL8B levels promoted the malignant phenotype of HCC in vitro and in vivo. Notably, ARL8B also induced epithelial-to-mesenchymal transition (EMT) in HCC cells. Mechanistically, the results of bioinformatics analysis combined with mass spectrometry revealed the potential downstream target molecule RAB2A of ARL8B. ARL8B directly interacted with RAB2A and increased the levels of GTP-bound RAB2A, thereby contributing to the activation of the extracellular signal-regulated kinase (ERK) signaling pathway. Interestingly, knockout of ARL8B in Hep3B cells enhanced the antitumor activity of lenvatinib in vitro and in vivo. Furthermore, AAV-shARL8B enhanced the inhibition of HCC growth through lenvatinib, providing new insights into its mechanism of action in lenvatinib-insensitive patients. In conclusion, ARL8B promotes the malignant phenotype of HCC and EMT via RAB2A mediated activation of the MAPK/ERK signaling pathway and is expected to be a valuable prognostic indicator and therapeutic target for HCC patients.

Assessing outcomes for patients receiving chemotherapy in the intensive care unit.

190 Background: Despite the low in-hospital mortality rate (9%) for Intensive Care Unit (ICU) stays in the US, outcomes for patients with cancer undergoing chemotherapy in the ICU remains unclear. We aimed to assess survival in patients with cancer (liquid, solid tumor and allogeneic stem cell transplant (alloSCT) receiving chemotherapy at our institution and identify patient characteristics for enhanced chemotherapy stewardship. Methods: We analyzed pharmacy data for patients with confirmed malignancies who received chemotherapy while admitted to the ICU at our institution from 1/1/21 to 12/31/23, excluding non-cancer patients and those on home oral regimens. Primary endpoints included 14-day, 30-day, and 90-day survival. Secondary analyses examined survival differences by age, ECOG performance status, and treatment history. Survival differences among patient subtypes were evaluated using Z-tests. Results: We identified 74 unique patients who received chemotherapy for cancer. 54 had liquid tumors, 5 were post-alloSCT, and 15 had solid tumors. The 90-day survival rate was 47% overall: 46% for the liquid tumor group, 80% for the alloSCT group, and 40% for the solid tumor group. When further stratified by tumor type, higher 90-day survival was variable; see Table 1 for details). In patients with lung cancer, 90-day survival was worse for non-small cell lung cancer without tumor mutations (0%, n=2) than those with targetable mutations (50%, n=4) or small cell lung cancer (33%, n=3). An ECOG performance status of 3-4 showed poorer 90-day survival in liquid tumors (23%) compared to ECOG 1-2 (74%; 95% CI 0.26 , 0.76). Solid tumors showed no significant ECOG differences (50%, 40%). Treatment-naive status showed higher 90-day survival in liquid tumors (59%) compared to treatment-resistant tumors (18%; 95% CI 0.17, 0.65), but not in solid tumors (50%, 20%). Conclusions: Our findings suggest generally unfavorable 90-day outcomes for ICU chemotherapy patients, especially those aged over 75, with multiple therapy lines, or ECOG status 3-4. Survival rates varied significantly across tumor types. We are currently broadening our study to include all solid tumor cancer patients. While this is a limited sample, this underscores the need for careful chemotherapy stewardship and advanced care planning in ICU settings. 90-day survival of solid and liquid tumor patients receiving chemotherapy in the ICU by select cancer diagnoses.

Unraveling molecular and clinical aspects of ALKBH5 as dual role in colorectal cancer.

This study investigates the dual role of ALKBH5, an eraser enzyme, in colorectal cancer (CRC), focusing on how N6-methyladenosine (m6A) mutations influence CRC development and progression. We reviewed various studies that highlighted the role of ALKBH5 in colorectal cancer (CRC). This includes the impact of ALKBH5 on tumor cell behavior including immune system interactions, invasion, and proliferation in CRC. We also looked into how ALKBH5 acts as a tumor suppressor under different conditions analyzed clinical data to assess the impact of ALKBH5 expression on outcomes in colorectal cancer patients. In CRC, ALKBH5 plays a dual role. In certain situations, it inhibits the progression of the tumor, but in other circumstances, it promotes tumor growth and immunosuppression. The interaction with RABA5 plays a role in the development of CRC. Having elevated levels of ALKBH5 has been associated with unfavorable patient outcomes, such as reduced survival rates and more advanced cancer stages. Various factors, including tumor differentiation, TNM stages, and carcinoembryonic antigen (CEA) levels, be linked to ALKBH5 expression. ALKBH5 plays a complicated and situation-specific role in colorectal cancer (CRC). Targeting ALKBH5 could result in novel therapy options that balance its tumor-promoting and tumor-fighting properties in CRC. Further research into m6A alterations and ALKBH5 could enhance CRC treatment approaches and patient outcomes.

Silencing EPHB2 diminished the malignant biological properties of esophagus cancer cells by blocking autophagy and Wnt/β-catenin pathway.

Eph receptor B2 (EPHB2) is overexpressed in some tumors and relevant to unfavorable outcomes of tumor patients. By searching Gene Expression Profiling Interactive Analysis and KM Plot websites, we discovered that EPHB2 was highly expressed in patients with esophageal cancer, leading to poor prognosis. However, the role and molecular mechanism of EPHB2 in esophagus cancer is unknown. Our study aims to unveil the underlying mechanism by which EPHB2 modulates the biological properties of esophagus cancer cells. After si-EPHB2 transfection, the malignant biological properties of esophagus cancer cells were determined by several biological experiments. IWP-4 was applied to block Wnt/β-catenin signaling pathway. The expressions of autophagy and Wnt/β-catenin signaling pathway relevant molecules were tested by western blot assay. An increased expression of EPHB2 was happened in esophagus cancer samples and loss of EPHB2 diminished esophagus cancer cells proliferation, migration, and invasion. Moreover, our data showed that depletion of EPHB2 blocked the autophagy and in-activated Wnt/β-catenin signaling pathway in esophagus cancer cells. While, IWP-4 treatment inhibited the autophagy and limited esophagus cancer cells proliferation, migration, and invasion. Moreover, EPHB2 knocked down strengthened the effect of IWP-4 treatment in regulating esophagus cancer cells proliferation, migration, and invasion. Finally, we illustrated that EPHB2 regulated the biological properties of esophagus cancer cells by modulating autophagy and Wnt/β-catenin signaling pathway. Our study illustrated that EPHB2 might be a worthwhile target considering for the treatment of esophagus cancer.

Gut-related molecules as potential biomarkers in patients with decompensated cirrhosis

Introduction and ObjectivesMicrobial translocation contributes to cirrhosis progression and complications. This study aims to investigate whether molecules related to intestinal permeability or microbial translocation can serve as prognostic biomarkers in patients with decompensated cirrhosis. Materials and MethodsWe prospectively evaluated hospitalized patients with decompensated cirrhosis for liver function, complications during hospitalization, in-hospital mortality, composite outcomes of in-hospital mortality and complications, 12-month mortality, and survival rates. Blood samples were collected upon admission, and 1,3 beta-d-glucan, zonulin, calprotectin, and lipopolysaccharide-binding protein were measured using commercial kits. ResultsNinety-one patients with decompensated cirrhosis were enrolled. The mean age was 58 ± 12 years; 57% were male. The three main cirrhosis etiologies were hepatitis C (35%), alcohol (25%), and non-alcoholic steatohepatitis (17%). In terms of liver function, 52% were Child C, and 68% had model for end-stage liver disease ≥15. The in-hospital and one-year mortality rates were 31% and 57%, respectively. Child-Pugh, 1,3 beta-glucan, and model for end-stage liver disease were positively correlated; zonulin was associated with complications during hospitalization (acute kidney injury) and composite outcomes, and calprotectin was associated with all outcomes except 12-month mortality. ConclusionsSerum calprotectin and zonulin levels emerge as noninvasive prognostic biomarkers for potentially unfavorable outcomes in patients with decompensated cirrhosis.

The association between physical activity and delayed neurocognitive recovery in elderly patients: a mediation analysis of pro-inflammatory cytokines

BackgroundDelayed neurocognitive recovery (dNCR) can result in unfavorable outcomes in elderly surgical patients. Physical activity (PA) has been shown to improve cognitive function, potentially by reducing systemic inflammatory responses. However, there is a lack of supportive data indicating whether PA has a protective effect against dNCR.AimsTo examine the correlation between dNCR and PA, and to further analyze if pro-inflammatory cytokines mediate this relationship.MethodsThis study is a prospective nested case-control investigation of elderly patients who had knee replacement surgery. dNCR was defined as a decline in cognitive function compared with baseline by using a battery of neuropsychological tests. PA was assessed with the Physical Activity Scale for the Elderly (PASE). Enzyme-linked immunosorbent assay (ELISA) was used to measure the serum concentrations of IL-6, IL-1β, and TNF-α. Multivariable logistic regression analysis was conducted to assess the association between PA and dNCR. Mediation analysis was employed to evaluate whether pro-inflammatory cytokines mediate the relationship between them.ResultsA cohort of 152 patients was included, resulting in an incidence rate of dNCR of 23.68%. PA was associated with dNCR after full adjustment [OR = 0.199, (95% CI, 0.061; 0.649), P = 0.007]. Mediation analysis showed that the IL-6 mediated the statistical association between PA and dNCR, with mediation proportions (%) of 77.68 (postoperative concentration of IL-6) or 27.58 (the absolute change in IL-6 before and after surgery).ConclusionsPA serves as a protective factor against dNCR, possibly through the reduction of pro-inflammatory cytokine concentrations.The Chinese Clinical Trail Registry: www.http://chictr.org.cn, Registration No. ChiCTR2300070834, Registration date: April 24, 2023.

Beyond the Gut: Exploring Cardiovascular Implications of Celiac Disease.

Celiac disease (CD) is an autoimmune disorder that presents with gastrointestinal symptoms including diarrhea, weight loss, and abdominal bloating due to the inflammation in the small intestine. It has been associated with various extraintestinal manifestations, including mucocutaneous findings such as dermatitis herpetiformis, anemia, dental enamel defects, osteoporosis, and arthritis. Studies have revealed an increasing association between CD and cardiovascular diseases (CVDs), including atherosclerosis, cardiomyopathy, and arrhythmia. Chronic inflammation, nutritional deficiencies from malabsorption, endothelial dysfunction, thrombophilic autoantibodies, thrombocytosis, and protein C and S deficiency have been proposed as the probable mechanisms for the association between the 2 conditions. This article aims to provide a review of the pathophysiological mechanism of celiac disease causing various CVDs and to compare and contrast the existing studies suggesting both favorable and unfavorable CVD outcomes in patients with CD.
