Summary: Diabetic retinopathy is a retinal disease associated with hyperglycemia in diabetes patients, affecting both the central and peripheral retina. Its major mechanism involves oxidative stress caused by elevated production of reactive oxygen species, which is particularly harmful to the retina due to its high metabolic activity. This review provides an overview of the role of oxidative stress in diabetic retinopathy, including the formation and effects of advanced glycation end-products, metabolic memory, and non-coding RNA, as well as potential therapeutic strategies.

Summary: This study examined the relationship between diabetic retinopathy (DR) and systemic factors in 261 patients with type 2 diabetes. Logistic regression analyses revealed that the duration of diabetes, average and highest HbA1c levels, and grade of diabetic nephropathy (DN) significantly correlated with the development of DR. Additionally, the severity of DR was significantly correlated with the duration of diabetes, average HbA1c level, and severity of DN. Logistic regression analyses also showed a significant correlation between the development of diabetic macular edema (DME) and the grade of DN. DN grade is associated with the development of DR and DME, and decreased renal function predicts the onset of DR.

Summary: This systematic review comprehensively summarizes the current understanding of the associations between dietary consumption, diabetic retinopathy (DR), and diabetic macular edema (DME). The review found that higher intakes of fruits, vegetables, dietary fibers, fish, a Mediterranean diet, oleic acid, and tea were protective against DR, while high intakes of diet soda, caloric intake, rice, and choline were associated with a higher risk of DR. There was no association between vitamin C, riboflavin, vitamin D, milk, and DR. A single study assessed dietary intake and DME, and found a risk of high sodium intake for DME progression.

Summary: The study aimed to determine the importance of blood sugar control, blood pressure, and other systemic factors on the risk of diabetic retinopathy progression. The findings confirmed that glucose control, as measured by HbA1c, was the most important modifiable risk factor, followed by blood pressure control and total cholesterol. Non-white patients generally had a higher risk of progression to diabetic retinopathy, while Asian patients were less likely to develop diabetic macular edema.

Summary: This study investigated the correlation between serum inflammatory and metabolic biomarkers in patients with diabetic retinopathy (DR) and diabetic macular edema (DME). The results showed significant differences in the levels of IL-6 and CRP between patients with and without DR, with a positive correlation between IL-6 and CRP and the severity of DR. Only IL-6 was found to be significantly elevated in DR patients with DME compared to those without DME. None of the metabolic markers correlated significantly with DR and DME.

Summary: Retinal Muller glial dysfunction and intracellular edema in diabetic retinopathy (DR) are associated with down-regulation of Aquaporin 11 (AQP11). AQP11 overexpression alleviates intracellular edema, enhances glutamate metabolism, and reduces cell death. The down-regulation of AQP11 in DR is mediated by the miRNA-AQP11 axis, which is partially reversed by AQP11 overexpression. Targeting AQP11 regulation may provide a new therapeutic strategy for diabetic macular edema (DME).

Summary: The study assessed differences in macular thickness evolution after uncomplicated cataract surgery between non-diabetic subjects and diabetic patients without diabetic retinopathy using SD-OCT. Results showed that there was no increase in foveal, parafoveal, and perifoveal retinal thickness on postoperative day 7, but thickness values increased on days 30, 90, and 180 after surgery in both groups, peaking at 90 days. There were no differences in macular thickness before or after surgery between diabetic and non-diabetic patients.

Summary: Subthreshold micropulse laser treatment has shown potential in treating diabetic macular edema, but its mechanism of action and most effective treatment methods are not yet fully understood, requiring further research. The treatment appears to normalize specific retinal neuroinflammatory metabolic pathways long-term, contributing to the restoration of retinal homeostasis and the curtailing of local inflammatory processes. Optimized and standardized parameters are key to ensuring effective and safe treatment.

Summary: The study found that the morphological responses of retinal microglia to electrical overstimulation injury depended on their spatial location relative to the electrode lumen, leading to three different morphological responses. These responses included severely injured microglia becoming immotile ball-like processes, surviving microglia rapidly extending filopodia towards the damage zone, and a fading of fluorescence in deeper outer microglia under the electrode.

Summary: Recent clinical studies have suggested that a common polymorphism of the BDNF gene may be related to the severity of fatigue following cancer treatment. In this study, transgenic mice homozygous for the Val66Met BDNF gene were used to investigate the effect of the polymorphism on fatigue-like behavior. The results showed that the Val66Met mice lost more weight during the baseline wheel-running period and exhibited a less severe fatigue-like phenotype during the first week after chemotherapy treatment.

Summary: This study evaluated the associations between cytokine concentrations and symptom profiles in women with breast cancer. The results showed that cytokine concentrations differed between extracellular vesicles (EVs) and soluble fractions. Several pro-inflammatory cytokines were positively associated with depressive symptoms and fatigue in both older and younger age groups. Furthermore, older patients with a specific symptom profile had higher levels of EV GM-CSF compared to patients with a different symptom profile. These findings suggest that EVs may serve as potential biomarkers for understanding underlying mechanisms of different symptom profiles in breast cancer patients.

Summary: This study explored the relationship between the single-nucleotide polymorphism (SNP) rs6265 of brain-derived neurotrophic factor (BDNF) and psychoneurological (PN) symptoms in female cancer survivors. The results showed that participants with the Met/Met genotype reported worse cancer-related fatigue and neuropathic pain, and that cancer-related fatigue was correlated with other PN symptoms, particularly depression. These correlations were stronger in participants with the Met/Met genotype. Therefore, the BDNF rs6265 genotype may influence the PN symptoms experienced by female cancer survivors.
