Aim: A clinical comparative trial was conducted to compare the levels of glycosylated hemoglobin (HbA1c) in patients with diabetic cystoid macular edema (CME) with and without serous macula detachment (SMD).
Materials And Methods: Thirty patients (group 1) with diabetic CME in both eyes, but without SMD, and 30 patients (group 2) with diabetic CME and SMD in both eyes documented by optical coherence tomography (OCT) and fundus fluorescein angiography (FFA), were included in the study. In addition to the measurement of central macular thickness by OCT and visual acuity (VA) (as logMAR) using the the early treatment diabetic retinopathy study (ETDRS) chart, the concentrations of HbA1c were measured by high performance liquid chromatography (HPLC). Statistical analysis was done by independent samples t test.
Results: The mean logMAR VA was 0.8 +/- 0.22 (1.0-0.5) in group 1 and 0.7 +/- 0.16 (1.0-0.6) in group 2. The mean central macular thickness, as determined by OCT, was 468.70 +/- 70.44 microm (344-602 microm) in group 1 and 477.80 +/- 73.34 microm (354-612 microm) in group 2. The difference between the groups was not statistically significant (P = 0.626). The mean HbA1c levels were 8.16 +/- 0.99% in group 1 and 10.05 +/- 1.66% in group 2. The difference between the groups was statistically significant (P < 0.001).
Conclusions: The presence of SMD and high HbA1c levels in the patients with diabetic CME may be indirectly suggestive of retinal pigment epithelium dysfunction.

Division of Cardiology, Department of Internal Medicine, Ilsan Paik Hospital, Inje University College of Medicine, Goyang, Republic of Korea.
Background: Amiodarone is an effective anti-arrhythmic drug; however, it is frequently associated with thyroid dysfunction. The aim of this study was to investigate the incidence and risk factor of amiodarone-induced dysfunction in an iodine-sufficient area.
Methods: This retrospective cohort study included 27,023 consecutive patients treated with amiodarone for arrhythmia, using the Korean National Health Insurance database.
Background: To investigate the effectiveness of different bariatric metabolic surgeries in improving metabolic syndrome indicators in patients.
Methods: A retrospective analysis was conducted on obese patients who underwent laparoscopic sleeve gastrectomy (LSG), laparoscopic sleeve gastrectomy + jejunojejunal bypass (LSG + JJB), and laparoscopic Roux-en-Y gastric bypass (LRYGB). Patients were categorized into groups based on their surgical procedure: LSG (N = 199), LSG + JJB (N = 242), and LRYGB (N = 288).
Marine-derived bioactive compounds for neuropathic pain: pharmacology and therapeutic potential.

Neuropathic pain, a challenging condition often associated with diabetes, trauma, or chemotherapy, impairs patients' quality of life. Current treatments often provide inconsistent relief and notable adverse effects, highlighting the urgent need for safer and more effective alternatives. This review investigates marine-derived bioactive compounds as potential novel therapies for neuropathic pain management.

Background: Chronic inflammation is well recognized as a key factor related to renal function deterioration in patients with diabetic kidney disease (DKD). Neutrophil extracellular traps (NETs) play an important role in amplifying inflammation. With respect to NET-related genes, the aim of this study was to explore the mechanism of DKD progression and therefore identify potential intervention targets.

Introduction: More than half of diabetes patients are Asians, and their tolerance to antidiabetic drugs may differ from that of non-Asians. Oral semaglutide has recently gained attention for its advantages in glycemic and body weight control. However, its effects across different ethnic groups remain unknown.
