The prognostic significance of HDL-associated apolipoproteins in ascitic fluid from patients with cirrhosis and spontaneous bacterial peritonitis
Abstract Apolipoproteins (Apo) A-I and A-II are major components of high-density lipoproteins (HDL) with immunomodulatory functions. Low serum apoA-I levels indicate complications of cirrhosis. We hypothesized that HDL-associated apolipoproteins in ascitic fluid (AF) are differentially abundant during spontaneous bacterial peritonitis (SBP). Serum and non-infected AF samples from 18 patients with cirrhosis (cohort 1) were analyzed using LC–MS/MS to identify differentially regulated apolipoproteins. In cohort 2, samples from 59 patients with SBP and 59 without were analyzed for AF apoA-II and apoA-I concentrations using ELISA, and cumulative 90-day transplant-free survival was analyzed. Proteomic analysis indicated depletion of AF apoA-II in the absence of SBP. Lower AF apoA-II and apoA-I correlated with lower AF protein and albumin, higher serum bilirubin, and lower platelets. During SBP, AF apoA-II levels significantly increased, leading to higher apoA-II/apoA-I ratios. AF apoA-II, but not apoA-I, correlated with peritoneal IL-6 concentrations. AF apoA-II > 45 µg/ml during SBP indicated an increased risk of death or transplantation within 90 days and remained a predictor of transplant or death after adjustment for age and MELD (adjusted hazard ratio, 2.59; 95% CI, 1.08–5.91; P = 0.032). In summary, the composition of HDL-associated apolipoproteins in ascites is altered during SBP and correlates with disease course.

Self-assessment of quality of life in patients after suffering from aneurysmal subarachnoid hemorrhage, principal component analysis
Abstract Quality of life (QoL) is one of the parameters that characterize the treatment success after aneurysmal subarachnoid hemorrhage, along with overall survival and independent living without the need for care. Thus, the main aim of this research was to evaluate the quality of life of patients after endovascular or microsurgical treatment of ruptured cerebral aneurysms. This study was performed at the Jena University Hospital in Germany. A total of 32 patients completed the German version of the WHO QoL Questionnaire during routine follow-up visits at our neurovascular outpatient clinic between January and September 2024. Analyses were stratified by the type of treatment. Patients who underwent endovascular treatment have better subjective reports of QoL in the psychological and environment domains, whereas those who underwent microsurgical clipping showed better outcomes in physical and social domains. Aneurysm location did not significantly impact QoL. To conclude, these findings suggest that different treatment modalities influence distinct aspects of QoL. Implementing treatment-tailored strategies, alongside comprehensive management of subarachnoid hemorrhage-related risks, may further enhance recovery and optimize functional outcomes.
Fabrication, spectroscopic inspection, biological evaluation of some transition metal complexes with bis- azomethine ligand and γ-ray irradiation dose effect
Abstract A new bis- azomethine ligand N′,N′′′-(2,2′-(((1E,1′E)-cyclohexa-2,5-diene-1,4-diylbis(methanylylidene))bis(azanylylidene))bis(benzoyl))di(picolinohydrazide) and its Cd+2 (1), Hg+2 (2) and Co+2 (3) complexes have been fabricated. Via FT-IR, UV/Vis., 1H-NMR spectroscopy and XRD, in addition to magnetic moment, elemental, molar conductance and thermal analysis, the structure of synthesized compounds was explored. The parent complexes (1,2) have been irradiated by 60Co radioactive source γ-rays at room temperature with dose values of 150 and 200 kGy to get irradiated samples (1R and 1R*) and (2R and 2R*), respectively. The structural of the irradiated samples were studied by the same techniques as for the parent complexes. The cytotoxicity of the ligand and its Cd+2 and Hg+2 complexes against breast (MCF-7) and hepatocellular cancerous cells (HepG-2) was evaluated. The chelates are significantly more potent compared to the ligand. Moreover, these compounds have been screened for their antimicrobial potency. The finding showed that the parent metal complexes demonstrated promising antimicrobial activity against gram −ve (Escherichia coli) and gram + ve (Staphylococcus aureus) bacterial species and two fungal species (Candida albicans and Aspergillus nigar) as well. The complexes exhibited greater antimicrobial potency than Ampicillin and Nystatin.
References to unbiased sources increase the helpfulness of community fact-checks
Abstract Community-based fact-checking is a promising approach to address misinformation on social media at scale. However, an understanding of what makes community-created fact-checks helpful to users is still in its infancy. In this paper, we analyze the determinants of the helpfulness of community-created fact-checks. For this purpose, we draw upon a unique dataset of real-world community-created fact-checks and helpfulness ratings from X’s (formerly Twitter) Community Notes platform. Our empirical analysis implies that the key determinant of helpfulness in community-based fact-checking is whether users provide links to external sources to underpin their assertions. On average, the odds for community-created fact-checks to be perceived as helpful are 2.33 times higher if they provide links to external sources. Furthermore, we demonstrate that the helpfulness of community-created fact-checks varies depending on their level of political bias. Here, we find that community-created fact-checks linking to high-bias sources (of either political side) are perceived as significantly less helpful. This suggests that the rating mechanism on the Community Notes platform successfully penalizes one-sidedness and politically motivated reasoning. These findings have important implications for social media platforms, which can utilize our results to optimize their community-based fact-checking systems.
