The updated 2021 WHO Classification of Central Nervous System (CNS) Tumors introduces, for the first time, an age-based approach to glioma classification, leveraging advances in molecular biology and epigenetics CNS tumors. This classification groups gliomas within category "Gliomas, glioneuronal tumors, neuronal tumors," distinguishing between adult-type pediatric-type diffuse gliomas, corresponding low-grade high-grade malignancies (LGG HGG), highlighting fundamental role age gliomagenesis. A review current literature deepens understanding age-related characteristics, differences, patterns gliomagenesis across groups, which is essential effective diagnosis treatment. Pediatric-type (pLGG aLGG) differ location, biological behavior, molecular-genetic profiles. Inherited syndromes (e.g., NF-1, TSC) associated with development are linked specific LGG subtypes occurring childhood, adolescence, adulthood. Moreover, pLGG differs from aLGG its potential malignant transformation spontaneous regression, as well mutations affecting MAPK (mitogen-activated protein kinase) pathway.

This study aimed to investigate the potential association between white blood cell counts and risk of lung cancer, including its subtypes, through Mendelian randomization (MR) analysis. We conducted a two-sample MR analysis using genome-wide (GWAS) summary statistics for both exposure traits (eosinophil count, neutrophil lymphocyte monocyte basophil total count) outcome (lung cancer subtypes). The GWAS dataset included 29,266 cases (11273 adenocarcinoma (LUAD), 7426 squamous carcinoma (LSCC), 2664 small (SCLC)) 56,450 controls. In analysis, we employed methods such as Inverse variance weighted (IVW), median, MR-Egger regression, pleiotropy residual sum outlier. revealed an elevated (WBC) count significantly increased LUAD (IVW: OR = 1.484, 95% CI 1.219–1.749, p 0.003). results confirmed causal relationship 1.687, CI:1.542–1.830, < 0.001).

ABSTRACT Background The exact nature of the link between breast cancer and meningiomas is unknown, although observational studies have shown a correlation two. Using two‐sample Mendelian randomization (MR) strategy, we aimed to investigate effect on meningiomas. Methods Three sets genetic instruments were utilized in this study based publicly available summary data. For cancer, selected 62 strongly associated SNPs; separate datasets curated for HER2‐positive HER2‐negative subtypes. MR analyses included outlier testing, MR‐Egger regression, MR‐PRESSO, weighted median, inverse variance approaches. Results analysis demonstrated significant evidence cancer's meningioma risk (OR = 1.213, 95% CI 1.054–1.396, p 0.007), supported by 1.456, 1.066–1.988, 0.021) though not median method 1.095, 0.914–1.311, 0.326).

While endometriosis (EM) has been previously associated with multiple immune factors, the causal relationship underlying these associations remains unclear. In this study, Two-sample Mendelian randomization (MR) method was employed to investigate between 731 cell traits and EM based on tabulated data from genome-wide association studies (GWAS). MR includes inverse variance weighting (IVW), weighted median (WM), MR-Egger, model, simple model. IVW is used as primary for judging effects. Peripheral blood obtained patients, positive phenotype confirmed using flow cytometry. After P-value correction, our two-sample showed that CD28 CD28+ DN (CD4-CD8-) had a suggestive (β =0.040, 95% CI =1.02-1.06, P =0.00029, PFDR = 0.1984). The results of other two main methods were similar: Weighted (OR =1.031, =1.00-1.07, =0.082); MR-Egger =1.032, =1.10-1.06, =0.044). cytometry indicated expression level (CD4-CD-8) significantly increased in ectopic intima patients.

Diabetes mellitus (DM), herpes zoster (HZ) and its sequelae, post-herpetic neuralgia (PHN), are common in elderly individuals. Previous observational studies have shown that the prevalence of HZ PHN conjunction with DM is increasing. Nonetheless, few investigated causal relationships between risk PHN. A two-sample Mendelian randomization (TSMR) analysis was conducted on genome-wide association study (GWAS) data. We obtained four separate datasets for DM: type 1 diabetes (T1D), 2 (T2D), mother (mother-DM) father (father-DM), two independent anti-varicella-zoster virus IgG (VZV-IgG), a single GWAS The inverse variance weighted (IVW), MR‒Egger, median mode analyses were used to estimate causality. Genetically predicted T1D increased level VZV-IgG (IVW: OR=1.011, 95% CI 1.006-1.016, P -FDR=8.44×10-6).
