    Previous studies showed that tumors are associated with the increased inflammatory burden and neutrophil-to-lymphocyte ratio (NLR) is also associated with inflammatory conditions. However, there is no review on the role of NLR in meningioma. The goal of this study was to see if NLR has any prognostic and diagnostic value in meningioma. The search was conducted on PubMed, Scopus, and Web of Science up to 3 August 2023. A total of 23 studies were included in the systematic review, of which 13 were included in the meta-analysis. It was found that patients with high-grade meningioma had higher levels of NLR compared to those with low-grade meningioma (standardized mean difference [SMD] = 0.72, 95% confidence interval [CI]: 0.21–1.23, p = 0.006)]. In addition, we found that there was no difference between NLR levels of patients with meningioma and those with gliomas (SMD, −0.19, 95% CI: −0.47–0.10, p = 0.20). Also, higher levels of NLR were found in patients with meningioma compared with healthy controls (SMD = 0.56, 95% CI: 0.24–0.88, p = 0.01). Studies showed that an NLR > 2.4 differentiated high-grade and low-grade meningioma, an NLR > 2.74 differentiated high and low progression-free survival groups, and an NLR > 2.59 was associated with recurrence, with high sensitivity and specificity. However, the NLR did not predict postoperative pneumonia following meningioma resection. Because of the contradiction, our study did not clearly demonstrate the difference in NLR levels in meningioma and other pathologies, so more studies are needed on this subject. NLR had significant diagnostic and prognostic value in meningioma. In general, we inferred a strong link between systemic inflammation assessed by NLR and meningioma, based on elevated levels of NLR in patients with meningioma compared to healthy controls. In addition, NLR had significant predictive potential for the progression and recurrence of meningioma. The predictive potential increased when combined with other diagnostic tools such as fibrinogen level. NLR may guide clinical decision making as an inflammatory marker and its relationship to therapeutic efficacy. Full article

    Tuberculosis remains a global health concern, and its treatment usually involves potent first-line antitubercular drugs which are tempered by the risk of associated hepatotoxicity leading to noncompliance and drug resistance. In this review, medicinal plants with the potential of protection against antitubercular drug-induced hepatotoxicity in animal models were explored from scientific literatures. From literature published between 1999 and 2022, this review systematically extracted 68 studies that reported on medicinal plants with protection against antitubercular drug-induced liver toxicity in animal models. Isoniazid, pyrazinamide, rifampicin, and etambutol were the first-line drugs reported in the reviewed studies. The liver enzymes, antioxidant status, inflammatory markers, and improvement in the liver architecture were the criteria most frequently used by the reported studies to access hepatoprotection. These plants are rich in bioactive phytochemicals which exhibit their hepatoprotective properties via mechanisms such as antioxidant activity, anti-inflammatory effects, and detoxification enhancement. This review provides the hepatoprotective properties and mode of action of medicinal plants and encourages future perspectives marked by rigorous scientific research, clinical trials, and integrative medicine approaches. Albeit the challenges of standardization of herbal formulation, safety concerns and hurdles of the regulatory framework must be addressed as traditional medicinal plants offer a promise to mitigate antitubercular drug hepatotoxicity.

    Our capacity to recognize and manage allosensitized transplant recipients and optimize organ allocation has been greatly improved by the development of single-antigen bead tests for detecting human leukocyte antigen antibodies. The main drawbacks of this technology have been thoroughly discussed in the literature, covering problems like artifacts that result in nonspecific background, variability, lack of uniformity, and difficulties in data interpretation. Consequently, it is not always easy to understand single-antigen bead data. This review will discuss the interpretation of donor-specific antibody data while considering the associated technical limitations. To ensure the correct clinical application of this test and to enhance the quality of antibody data used to support published clinical research in the era of epitope-based computational matching algorithms, a detailed understanding of the single-antigen bead assay is necessary.

    The huge burden of type 1 diabetes mellitus (T1DM) has been a source of concern globally since the Industrial Revolution in the 18th–19th centuries. To this end, studies have shown that certain environmental changes that accompanied the Revolution may have increased the risk and burden of the disease in genetically predisposed individuals. However, documented studies that synthesize these environmental triggers are scarce. As a result, the current study was conceived to synthesize the environmental triggers of T1DM to boost public awareness. Relevant information was retrieved from reputable academic databases; namely, Scopus, PubMed, SpringerLink, and Embase. The results showed that chemical exposure, viral infection, gut microbiome disruption, vitamin and mineral deficiencies, inadequate or exclusive breastfeeding, as well as early exposure to infant feeding formulas could increase the risk and burden of T1DM in genetically predisposed individuals. As a consequence, these triggers could compromise the expression of certain genes involved in insulin synthesis and immune function, such as the human leukocyte antigen (HLA), insulin (INS), cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), and protein tyrosine phosphatase non-receptor type 22 (PTPN22) genes. This would result in a dysfunctional immune system in which immune cells, such as T-cells and B-cells and molecules, such as cytokines would attack self-tissues, thus causing autoimmunity of the pancreatic beta cells. Environmental triggers could also induce the T1DM pathophysiology by modifying the epigenome of the mentioned genes. Furthermore, some epigenetic changes could be reversed, which would infer that treatment procedures that would include the pathophysiology of the environmental triggers could be more effective.

    Emerging evidence suggests that RNA-binding motif (RBM) proteins are involved in hepatocarcinogenesis and act either as oncogenes or tumor suppressors. The objective of this study was to investigate the role of RBM34, an RBM protein, in hepatocellular carcinoma (HCC). We first examined the expression of RBM34 across cancers. The correlation of RBM34 with clinicopathological features and the prognostic value of RBM34 for HCC was then investigated. Functional enrichment analysis of RBM34-related differentially expressed genes (DEGs) was performed to explore its biological function. RNA sequencing (RNA-seq) was applied to identify downstream genes and pathways affected upon RBM34 knockout. The correlation of RBM34 with immune characteristics was also analyzed. The oncogenic function of RBM34 was examined in in vitro and in vivo experiments. RBM34 was highly expressed in hepatocellular carcinoma and correlated with poor clinicopathological features and prognosis. RBM34 was positively associated with tumor immune cell infiltration, biomarkers of immune cells, and immune checkpoint expression. A positive correlation was also observed between RBM34, T cell exhaustion, and regulatory T cell marker genes. Knockout of RBM34 significantly inhibited cell proliferation, migration, and xenograft tumor growth, and sensitized HCC cells to sorafenib treatment. RBM34 inhibition reduced FGFR2 expression and affected PI3K-AKT pathway activation in HCC cells. Our study suggests that RBM34 may serve as a new prognostic marker and therapeutic target of HCC.

    Naringenin is an anti-inflammatory flavonoid that has been studied in chronic liver disease. The mechanism specific to its antifibrosis activity needs further investigation This study was to focused on the cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS) pathway in hepatic stellate cells and clarified the antifibrosis mechanism of naringenin. The relationship between the cGAS-stimulator of interferon genes (STING) pathway and liver fibrosis was analyzed using the Gene Expression Omnibus database. Histopathology, immunohistochemistry, fluorescence staining, Western blotting and polymerase chain reaction were performed to assess gene and protein expression levels associated with the cGAS pathway in clinical liver tissue samples and mouse livers. Molecular docking was performed to evaluate the relationship between naringenin and cGAS, and western blotting was performed to study the expression of inflammatory factors downstream of cGAS in vitro. Clinical database analyses showed that the cGAS-STING pathway is involved in the occurrence of chronic liver disease. Naringenin ameliorated liver injury and liver fibrosis, decreased collagen deposition and cGAS expression, and inhibited inflammation in carbon tetrachloride (CCl4)-treated mice. Molecular docking found that cGAS may be a direct target of naringenin. Consistent with the in vivo results, we verified the inhibitory effect of naringenin on activated hepatic stellate cells (HSCs). By using the cGAS-specific agonist double-stranded (ds)DNA, we showed that naringenin attenuated the activation of cGAS and its inflammatory factors affected by dsDNA. We verified that naringenin inhibited the cGAS-STING pathway, thereby reducing the secretion of inflammatory factors by HSCs to ameliorate liver fibrosis. Interrupting the cGAS-STING pathway helped reverse the fibrosis process. Naringenin has potential as an antihepatic fibrosis drug. Full article
