Purpose: Tranexamic acid (TXA) is a widely used antifibrinolytic agent that can also cause a decrease in vascular permeability. We hypothesized that TXA could improve macular edema (ME) that is caused by an increase in retinal vascular permeability. The aim of this study is to evaluate the efficacy of oral TXA for ME associated with retinal vein occlusion (RVO) or diabetic ME (DME). Patients and methods: Oral TXA (1,500 mg daily for 2 weeks) was administered to patients with persistent ME secondary to RVO (7 eyes) and DME (7 eyes)...

Purpose: Real-life clinical outcomes of patients treated with anti-VEGF drugs for neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), or macular edema secondary to branch retinal vein occlusion (BRVO) are often inferior to results from randomized clinical trials. This observational cohort study investigates treatment adherence and real-life clinical outcomes within the first year of treatment. Patients and methods: A total of 708 treatment-naïve patients (466 nAMD, 134 DME, and 108 BRVO) were included...

Importance: In diabetic macular edema (DME), identification of baseline markers on spectral-domain optical coherence tomography (SD-OCT) and their association with severity of diabetic retinopathy (DR) might aid in disease management and the design of future trials. Objective: To examine associations between DR severity, retinal morphology on SD-OCT, and visual acuity in participants with DME. Design, Setting, and Participants: This cross-sectional observational case series was conducted at a single tertiary care referral center...

Microvascular complications of pediatric-onset type 1 diabetes are common in low-income countries. In this study, we aimed at reviewing microvascular outcomes in 6 cases with type 1 diabetes over 14 to 31 years of follow-up. Severe proliferative diabetic retinopathy (PDR) and/or diabetic macular edema (maculopathy) (DME) and overt diabetic nephropathy (macroalbuminuria) were seen among 4 of 6 patients, whereas severe diabetic peripheral neuropathy with Charcot neuroarthropathy was seen in 1 patient only, who had the longest duration of follow-up...

BACKGROUND: Inter-individual variability in hepatic drug metabolizing enzyme (DME) activity is a major contributor to heterogeneity in drug clearance and safety. Accurate data on expression levels and activities of DMEs is an important prerequisite for in vitro-in vivo extrapolation and in silico based predictions. Characterization and assessment of inter-correlations of the major DMEs cytochrome P450s (CYPs) and UDP-glucuronosyltransferases (UGTs) have been extensively documented, but simultaneous quantification including other major DMEs has been lacking...

The present paper aims at presenting the methodology and first results of a detection system of risk of diabetic macular edema (DME) in fundus images. The system is based on the detection of retinal exudates (Ex), whose presence in the image is clinically used for an early diagnosis of the disease. To do so, the system applies digital image processing algorithms to the retinal image in order to obtain a set of candidate regions to be Ex, which are validated by means of feature extraction and supervised classification techniques...

OBJECTIVE: To examine the relationship between early response to anti-vascular endothelial growth factor (VEGF) treatment and visual prognosis. METHODS: We retrospectively separated 20 patients with persistent diabetic macular edema (DME) into two responder status groups based on the reduction of central macular thickness (CMT) from baseline to month 3: a delayed responder group (DRG) (≤25% CMT reduction, n = 11) and an immediate responder group (IRG) (>25% CMT reduction, n = 14)...

REVIEW

Transmission of morbilliviruses within and among marine mammal species has been documented in a variety of marine habitats. Cetacean morbillivirus spreads between cetacean species in the aquatic environment whereas both phocine distemper virus and canine distemper virus have been associated with transmission within and between pinniped and terrestrial carnivore species in their natural habitat and at the aquatic-terrestrial interface. Periodically these viruses have caused large epizootics involving thousands of animals, due to sustained intra-species virus transmission...

PurposeA pilot study to validate the collection of vitreous reflux (VR) after intravitreal injection using Schirmers tear strips was carried out. We assessed its efficiency for proteomics studies by estimating the differential expression of 27 cytokines using multiplexed bead array in diabetic macular oedema and proliferative diabetic retinopathy. To set, validate and assess the efficacy of Schirmer tear strips for collecting VR in patients undergoing intravitreal injections for diabetic macular oedema (DME)...

This review reports recent achievements in dimethyl ether (DME) synthesis via CO₂ hydrogenation. This gas-phase process could be considered as a promising alternative for carbon dioxide recycling toward a (bio)fuel as DME. In this view, the production of DME from catalytic hydrogenation of CO₂ appears as a technology able to face also the ever-increasing demand for alternative, environmentally-friendly fuels and energy carriers. Basic considerations on thermodynamic aspects controlling DME production from CO₂ are presented along with a survey of the most innovative catalytic systems developed in this field...

PURPOSE: The purpose of this study is to study the benefit of addition of oral fenofibrate to the current regimen of diabetic macular edema (DME) management and quantify its effect on macular thickness and visual function in DME. METHODS: Fifty-three eyes of 50 patients were randomized into treatment (Group A) (oral fenofibrate 160 mg/day) and control groups (Group B). Both groups underwent treatment of DME as per the standard treatment protocol of our hospital including intravitreal injections (anti-vascular endothelial growth factor/steroid) and grid laser...

AIM: To clarify the mechanism of infliximab treatment in diabetic macular edema (DME) and to provide a new alternative therapy for DME. METHODS: Rats were randomly divided into the control group, the model group and the infliximab treatment group. A diabetic rat model was created. The concentration of TNF-α in the vitreous body was detected by ELISA. The expressions of B-Raf, p38, claudin-1 and occludin in the retina were detected by Western blot. The integrity of the blood retinal barrier (BRB) was measured using Evan's blue as a tracer...

Substituting metals for either aluminum or phosphorus in crystalline, microporous aluminophosphates creates Brønsted acid sites, which are well known to catalyze several key reactions, including the methanol to hydrocarbons (MTH) reaction. In this work, we synthesized a series of metal-substituted aluminophosphates with AFI topology that differed primarily in their acid strength and that spanned a predicted range from high Brønsted acidity (H-MgAlPO-5, H-CoAlPO-5, and H-ZnAlPO-5) to medium acidity (H-SAPO-5) and low acidity (H-TiAlPO-5 and H-ZrAlPO-5)...

PURPOSE: To compare the functional and anatomical outcomes after a 0.2 µg/day fluocinolone acetonide (FAc) implant between vitrectomized and nonvitrectomized eyes with chronic diabetic macular edema (DME). METHODS: This is a retrospective, comparative analysis of 43 eyes with chronic DME. All eyes were treated with a single 0.2 µg/day FAc implant and followed up for a mean period of 8.5 months (median, 6.0 months; range, 1-21 months). The patients with a 0.2 µg/day FAc implant were divided into 2 groups: 24 eyes which had undergone pars plana vitrectomy prior to 0...
