Rationale: Internal limiting membrane (ILM) peeling and gas tamponade are the standardized treatments for macular holes (MHs). However, the close rate is low, and postoperative vision is unsatisfactory in large, chronic MHs. Currently, various modifications of the ILM flap techniques are being gradually applied for large MHs in the hope of obtaining better postoperative effects. This study described 2 successful cases achieved by "Sandwich-type" modified ILM flap covering technique in patients with large, chronic MHs.
Patient Concerns: A 62-year-old woman presented with decreased vision and visual distortion of the left eye for 18 months. Optical coherence tomography (OCT) showed the absence of full-thickness neuroepithelial tissue in the central fovea, with a minimum MH diameter of 742 μm and a base diameter of 1630 μm. A 57-year-old man experienced decreased visual acuity for 8 months. OCT showed the absence of full-thickness neuroepithelial tissue in the central fovea, with a minimum MH diameter of 713 μm and a basal diameter of 939 μm.
Diagnoses: Two patients were diagnosed with large, chronic MH based on the OCT results and duration of the hole.
Interventions: The 2 patients were treated with the "sandwich-type" modified ILM flap covering technique.
Outcomes: Large, chronic MH closure was observed using SD-OCT, and the BCVA improved. The patients were very satisfied with the postoperative results.
Lessons: "Sandwich-type" modified ILM flap covering technique may be a safe, effective way for large, chronic MH.

Dysregulation of GABAergic inhibition is associated with pathological pain. Consequently, enhancement of GABAergic transmission represents a potential analgesic strategy. However, therapeutic potential of current GABA agonists and modulators is limited by unwanted side effects.

Background: Self-management interventions empower individuals to manage their chronic conditions and daily life after stroke. However, traditional in-person self-management interventions often face transportation and geographical barriers. Digital interventions may offer a solution to address this gap.

: China has the world's largest internal migrant population, yet chronic disease prevalence among this group remains largely overlooked. The integration of the internal migrant population into the local society may affect their noncommunicable disease prevalences and become a challenge for the public health system. This study aimed to explore the association between the social integration of China's internal migrant population and the prevalences of chronic diseases, including hypertension and diabetes.

Background/objectives: Although eligibility criteria for clinical trials significantly impact study outcomes, these criteria are often established without scientific justification, leading to delayed recruitment, small sample sizes, and limited study generalizability. Persistent Lyme disease (PLD) presents unique challenges due to symptom variability, inconsistent treatment responses, and the lack of reliable biomarkers, underscoring the need for scientifically justified eligibility criteria.
Objective: This study examines the effects of commonly used enrollment criteria on sample yield in PLD clinical trials using real-world data (RWD) from the MyLymeData patient registry.
