Summary: Severe acute pancreatitis (SAP) is a severe acute abdominal disease, and recent evidence suggests that maintaining intestinal homeostasis is crucial for managing this condition. Chitosan oligosaccharides (COS) with antioxidant properties have shown promising therapeutic effects in treating inflammatory diseases. This study demonstrated that COS administration alleviated the severity of SAP by reducing inflammation, oxidative stress, and restoring intestinal homeostasis, indicating its potential as a prebiotic agent for SAP treatment.

Summary: Ocular immune privilege refers to the ability of foreign tissue grafts placed in the eye to survive indefinitely. This privilege is maintained by various mechanisms, including the blood-ocular barrier, lack of lymphatics in the eye, production of immune-suppressing molecules in the ocular microenvironment, and induction of systemic regulatory immunity. Failure of ocular immune privilege can lead to uveitis, which is a group of inflammatory disorders that can cause vision loss. Current treatments for uveitis involve immunosuppressive and anti-inflammatory medications. Research on ocular immune privilege mechanisms and the development of novel uveitis treatments is ongoing.

Summary: This study aimed to develop a comprehensive grading system to objectively evaluate the progression of experimental autoimmune uveitis (EAU) in mice. Weekly fundus and optical coherence tomography (OCT) images were acquired over 12 weeks, and each mouse was graded based on changes seen on both types of images. The analysis of the clinical scores showed a gradual increase in inflammatory signs in EAU mice, with most signs reaching a plateau towards the end of the study period. The development of this grading system enhances the preclinical evaluation of novel uveitis treatments.

Summary: This study investigates the role of Nrf2 in the development of autoimmune uveoretinitis and suggests that Nrf2 deficiency exacerbates retinal inflammation, while activation of Nrf2 has a suppressive effect on the development of uveoretinitis.

Summary: Uveitis is a complex ocular inflammatory disease that can be caused by infections or autoimmune factors. While infectious uveitis can often be resolved with anti-infective therapy and corticosteroids, non-infectious uveitis requires a better understanding of inflammatory pathways to develop more effective treatments.

Summary: The study demonstrates that high ambient temperature exacerbates the severity of experimental autoimmune uveitis in mice, leading to an increase in Th1 and Th17 cell frequency, as well as elevated generation of neutrophil extracellular traps (NETs). These effects may be mediated by the NADPH oxidase-dependent pathway.

Summary: The eye is constantly exposed to solar radiations and vulnerable to reactive oxygen species, leading to biomolecular modifications in ocular diseases. Anterior eye segment injury originates from the imbalance of pro-oxidant/antioxidant levels, resulting in increased oxidative damage. Oxidative stress is related to various ocular diseases, such as dry eye, keratoconus, uveitis, and cataract, through mechanisms like inflammation and mitochondrial dysfunction. Biomarkers offer potential for predictive diagnostics of eye diseases. This review analyzes oxidative stress, inflammation, and the importance of biomarkers in anterior ocular diseases.

Summary: Uveitis is a group of inflammatory eye diseases characterized by infiltration of leukocytes into the uveal tissues. HLA-B27-positive uveitis displays a unique pattern of ocular leukocyte infiltration with a prominent presence of plasmacytoid and classical dendritic cells. These cells play a central role in predicted local cell-cell communication within the eye, suggesting their importance in HLA-B27-associated inflammation.

Summary: Chitosan oligosaccharides (COS) can effectively alleviate constipation by modulating gut microbiota, enhancing intestinal motility, inhibiting inflammatory responses, improving water-electrolyte metabolism, and preventing gut barrier damage. The balance of intestinal bacteria and metabolites plays a key role in this process, as shown in a study on loperamide-induced constipated mice.

Summary: The study demonstrated that betaine has anti-inflammatory effects in experimental autoimmune uveitis (EAU) rats by increasing serum superoxide dismutase levels, downregulating pro-inflammation molecules, and suppressing inflammation in the retina and ciliary bodies. This suggests that betaine plays a role in mitigating EAU through its anti-oxidation and anti-inflammatory activities.

Summary: This study aims to investigate the effectiveness of single-dose intravitreal dexamethasone (DEX) implants for patients with post-vitrectomy macular edema (ME) under silicone oil (SO) tamponade. The results suggest that the single-dose DEX implant treatment may benefit patients with recalcitrant post-vitrectomy ME under SO tamponade, with maximum central macular thickness (CMT) improvement observed at 1 month.

Summary: This study aimed to investigate the development, evolution, outcomes, and prognostic factors of lamellar macular hole (LMH) in highly myopic patients. The study identified four different traction-related LMH developmental processes with varying evolution and outcomes. LMHs caused by foveal thinning induced by epiretinal membranes were associated with the worst visual outcomes.

Summary: This study investigated biomarkers of OCT and OCTA for good visual outcomes in eyes with mCNV treated with anti-VEGF therapy. The study found that visual improvement was associated with thicker subfoveal choroid thickness and ellipsoid zone integrity at baseline, while OCTA biomarkers played a less important role in predicting visual outcomes of mCNV.

Summary: The purpose of this study is to describe the clinical characteristics and surgical treatment of secondary full-thickness macular hole (MH) after diabetic vitrectomy (DV) in patients with proliferative diabetic retinopathy (PDR). The study found that the formation of MH was related to unreleased tractional force and weakened foveal structure. The development of anterior proliferative vitreoretinopathy and epiretinal membrane (ERM) may also lead to MH. Various surgical techniques can be used for MH closure.

Summary: In exudative pachychoroid neovasculopathy (PNV), eyes with dilated choroidal vascular channels (DCVC) have a higher vascular density of macular neovascularization and poorer corrected distance visual acuity (CDVA) at baseline, and they also exhibit poorer visual and anatomical outcomes despite receiving more anti-VEGF injections.

Summary: The purpose of this study was to evaluate the rate and time to complete vascularization in premature infants and explore associated factors. The findings showed that lower birth weight, presence of retinopathy of prematurity (ROP), and antivascular endothelial growth factor therapy may delay complete vascularization. These results can contribute to a better understanding and management of persistent avascular retina in preterm infants.

Summary: The study investigated changes in the vitreoretinal interface after anti-vascular endothelial growth factor (anti-VEGF) treatment in highly myopic eyes. The prevalence of myopic macular retinoschisis (MRS) was 25.4%, with rates of progression and onset of 75.9% and 16.2% respectively. Outer retinal schisis and lamellar macular hole (LMH) were identified as risk factors for MRS progression and onset, while male sex and outer retinal schisis were risk factors for MRS progression. The study concluded that changes in the vitreoretinal interface, including progression, onset, and improvement of MRS, were observed after anti-VEGF treatment.

Summary: This study found that extended exposure to white or blue light can promote the expression of the Angelman syndrome-related gene UBE3A in the retina but not in the visual cortex. Additionally, it was observed that this light exposure caused changes in the chromatin structure of the Ube3a promoter, which further impacted gene expression.
