The uterine cervix and vaginal regions are infrequently infiltrated by lymphoma. Involvement of these topographic regions may constitute primary disease or more commonly represent a manifestation of systemic lymphomatous disease. Herein, we report an expanded spectrum of high-grade B-cell non-Hodgkin lymphomas comprising plasmablastic lymphoma (with and without plasmacytic differentiation), ALK-positive large B-cell lymphoma, and diffuse large B-cell lymphoma which involved the uterine cervix and/or vagina of 6 patients at initial diagnosis. These tumors clinically mimicked carcinoma and developed predominantly, but not exclusively, in the setting of human immunodeficiency virus infection.

The introduction of anti-tumor necrosis factor-α (anti-TNF-α) agents, particularly infliximab (IFX) and adalimumab (ADA), has significantly expanded the therapeutic arsenal for inflammatory bowel disease (IBD). While these biologics have demonstrated substantial efficacy, they are associated with a spectrum of potential adverse events (AEs). This study aims to evaluate and document these AEs to facilitate optimal patient selection and monitoring strategies of patients undergoing these therapies.

Despite the vast amount of water on Earth, only a small percent is suitable for consumption, and these resources are diminishing. Moreover, water resources are unevenly distributed, leading to significant disparities in access to drinking water between countries and populations. Increasing consumption and the expanding human population necessitate the development of novel wastewater treatment technologies and the use of water treatment byproducts in other areas, such as fertilisers.

Fibronectin glomerulopathy (FG) is caused by fibronectin 1 () gene mutations. A renal biopsy was performed on a 4-year-old girl with incidentally discovered proteinuria (150 mg/dL); her family history of renal disease was negative. Markedly enlarged glomeruli (mean glomerular diameter: 196 μm; age-matched controls: 140 μm), α-SMA-positive and Ki-67-positive mesangial cell proliferation (glomerular proliferation index 1.

The intensification of aquaculture has escalated disease outbreaks and overuse of antibiotics, driving the global antimicrobial resistance (AMR) crisis. Antimicrobial peptides (AMPs) provide a promising alternative due to their rapid, broad-spectrum activity, low AMR risk, and additional bioactivities, including immunomodulatory, anticancer, and antifouling properties. AMPs derived from aquatic invertebrates, particularly marine-derived, are well-suited for aquaculture, offering enhanced stability in high-salinity environments.

However, the genotype-phenotype correlations and the underlying pathogenic mechanisms remain poorly understood.
