Emerging evidence implicates immune dysregulation and neuroinflammation in the pathogenesis of epilepsy, yet the causal mechanisms remain unclear. This study aimed to investigate the causal effects of immune cells and inflammatory proteins on epilepsy and evaluate the mediating role of inflammatory proteins.

This study utilized the largest available genome-wide association study data on immune cell phenotypes and inflammatory proteins as exposures, and epilepsy genome-wide association study data from the FinnGen dataset as outcomes. Five Mendelian randomization (MR) methods were applied within a two-sample MR framework to assess causal effects. Furthermore, a two-step MR analysis was conducted to quantify the proportion of epilepsy and its subtypes influenced by immune cells through inflammatory proteins.

The two-sample MR analysis identified 32 immune cell phenotypes associated with epilepsy risk (19 risk-increasing, e.g., CD19+ B cells; 13 protective, e.g., regulatory T cell subsets). Subtype analyses revealed 30 immune phenotypes associated with generalized epilepsy and 26 with focal epilepsy. Eight inflammatory proteins showed suggestive causal effects on epilepsy: C-C chemokine ligand 23, C-X-C motif chemokine ligand 6, C-X-C motif chemokine ligand 11, and vascular endothelial growth factor A increased epilepsy risk, while interleukin-13 (IL-13), leukemia inhibitory factor receptor, tumor necrosis factor, and osteoprotegerin conferred protection. Mediation analysis indicated that inflammatory proteins mediated 6.3–13.5% of the immune effects on epilepsy. Specifically, CD14+CD16+ monocytes increased epilepsy risk through elevated C-C chemokine ligand 23 levels (8.5% mediation), while effector memory double-negative (CD4−CD8−) T cells reduced epilepsy risk via upregulation of IL-13 (6.3%). Sensitivity analyses confirmed the robustness of these findings (P heterogeneity/pleiotropy > 0.05). Although no associations reached Bonferroni-corrected significance, the findings implicate B cells, monocytes, regulatory T cells, and cytokines (e.g., IL-13, leukemia inhibitory factor receptor) in the pathogenesis of epilepsy, with inflammatory proteins acting as partial mediators.

These results enhance our understanding of immune-inflammatory pathways in epilepsy and highlight potential therapeutic targets. Future studies should validate these findings across diverse populations and further elucidate the molecular mechanisms underlying the identified associations.

Inflammatory bowel disease (IBD) is a chronic condition with significant health implications worldwide. In Nigeria, data on its prevalence and characteristics are limited, highlighting the need for comprehensive studies to better understand its epidemiology and clinical features in the region. This study aimed to assess the clinical presentation, endoscopic findings, and management challenges of IBD among patients undergoing colonoscopy in Nigeria.

Over five years (2019–2024), a multicenter, cross-sectional survey was conducted involving clinicians across Nigeria’s six geopolitical zones. It included a retrospective review of records from 18 centers. Data collection was conducted in two phases via Google Forms, focusing on care practices and detailed case information, including demographics, clinical features, histology, and treatment. Data analysis used descriptive statistics and tests for associations, with significance set at p < 0.05.

A total of 459 suspected IBD cases (9.7%) were identified among over 4,700 colonoscopies, with histological confirmation in 208 cases (4.4%), indicating the prevalence of IBD in the Nigerian patient population. The most common subtype was ulcerative colitis (53.9%), followed by Crohn’s disease (21.0%) and indeterminate colitis (25.0%). Regional variations were observed, with higher diagnosis rates in some zones (North-West: 14.9%; South-East: 1.4%). The predominant clinical feature was rectal bleeding. Endoscopic findings frequently showed pan-colitis (62%), with significant regional differences (p < 0.001), and management mainly involved medications such as acetylsalicylic acid derivatives (60.0%), with surgical options rarely employed (0.6%). Challenges included high medication costs and limited availability, which affected nearly half of the patients (49.4%; 46.2%).

IBD, though under-recognized, is present in the Nigerian population, with notable regional variation in prevalence and presentation. The primary clinical features align with global patterns, and significant barriers, such as medication costs and availability, hinder effective management. Increasing awareness, improving diagnostic infrastructure, and addressing treatment challenges are essential to enhance care and outcomes for patients with IBD in Nigeria.

Malignant mixed Müllerian tumor (MMMT) or carcinosarcoma of the female genital tract is a rare but highly aggressive malignancy.

We report a unique case of primary ovarian MMMT with poorly differentiated angiosarcoma as its homologous sarcomatous component in a 53-year-old woman with a known germline BRCA1 mutation who presented with a pelvic mass. She underwent staging cytoreduction surgery including total hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and pelvic and para-aortic lymph node dissections. The removed right ovarian tumor formed a 2.5 cm nodular to cystic mass replacing the entire organ. Microscopic examination revealed two distinct tumor components: high-grade serous carcinoma and poorly differentiated angiosarcoma. The proliferating sarcomatous cells were diffusely positive for CD31 and Factor VIII, but were negative for 100, SOX10 and cytokeratin. Both the serous carcinoma and angiosarcoma components demonstrated aberrant strong and diffuse p53 nuclear positivity. KRAS mutation analysis revealed guanine-adenine-thymine point mutation at codon 12 in both tumor components. Metastatic tumor was found involving the contralateral left ovary with the cellular composition of pure angiosarcomatous component.

This is the first report of an ovarian MMMT with angiosarcoma as its homologous sarcoma component. The presence of aberrant p53 expression and identical KRAS mutation in both the serous carcinoma and angiosarcoma components supports the theory of malignant mesenchymal transition/metaplasia in the development of MMMT.

Delirium, commonly observed in critically ill patients following intracerebral hemorrhage (ICH), is an acute neuropsychiatric disorder characterized by disturbances in attention, consciousness, and cognition. The underlying brain network mechanisms remain poorly understood. This study aimed to explore the functional connectivity (FC) of the ascending reticular activating system (ARAS) in delirium patients with basal ganglia ICH and to identify potential biomarkers for predicting delirium onset.

In this cross-sectional study, brain networkomics techniques were used to examine the FC within the ARAS in ICH patients with and without delirium. A two-sample t-test compared differences in ARAS connectivity between delirium and non-delirium groups, identifying abnormal brain regions and their corresponding FC values. Receiver operating characteristic curve analysis was then performed to evaluate the predictive value of FC for delirium onset.

A significant disruption in FC between the brainstem ARAS nuclei and the left parahippocampal gyrus was observed in ICH patients with delirium. The FC strength between these regions was a reliable predictor of delirium occurrence, with an area under the curve of 0.893, indicating high predictive accuracy.

The disruption of FC between the brainstem ARAS nuclei and the left parahippocampal gyrus may represent a key mechanism underlying delirium pathogenesis. The strength of this connectivity could serve as a potential biomarker for predicting delirium onset. Future research should focus on strategies to restore this connectivity as a potential treatment for early reversal of delirium.

Artemisia argyi H. Lév. & Vaniot essential oil (AAEO) holds significant pharmacological potential, but its application is constrained by hepatotoxicity. This study aimed to investigate the feasibility of reducing AAEO’s toxicity through storage and to evaluate changes in chemical composition, toxicity, and bioactivity.

Gas chromatography-mass spectrometry was used to analyze compositional changes during storage. Zebrafish acute toxicity tests and the liver-specific transgenic zebrafish model Tg(fabp10:EGFP) were used to assess toxicity. Antimicrobial, analgesic, and antioxidant assays evaluated variations in bioactivity.

Over the 150-day storage period, gas chromatography-mass spectrometry analysis identified 39 components. Zebrafish acute toxicity tests showed that the LD50 of AAEO stored for 0, 30, 60, 90, 120, and 150 days were 0.10 µL·mL−1, 0.10 µL·mL−1, 0.10 µL·mL−1, 0.11 µL·mL−1, 0.13 µL·mL−1, and 0.14 µL·mL−1, respectively, demonstrating a 40% reduction in acute toxicity after 150 days of storage. Using the liver-specific green fluorescent transgenic Tg(fabp10:EGFP) zebrafish model, the inhibition rates of AAEO on hepatic fluorescence intensity were measured at 68.5%, 43.5%, 42.6%, 37.8%, 34.6%, and 31.9% at different time points, confirming reduced hepatotoxicity after storage. Additionally, the antioxidant and analgesic activities of AAEO were significantly enhanced (p < 0.05) after storage, while the antibacterial activity decreased (p < 0.05).

After storage, AAEO significantly reduces hepatotoxicity, with a 40% decrease in acute toxicity after 150 days. Meanwhile, the antioxidant and analgesic activities of AAEO increase, while its antibacterial activity decreases after storage.
