Purpose: To present a cohort of treatment-naive patients with the neovascular form of age-related macular degeneration (nAMD) treated with aflibercept in a fixed regimen and evaluate the treatment response of three types of choroidal neovascular membrane (CNV)-occult (Type 1), classic (Type 2), and minimally classic (Type 4).
Methods: This was a multicentre, prospective, observational consecutive case series study. Patients diagnosed with three types of CNV of nAMD were treated in a fixed regimen (3 injections every 4 weeks, and then injections at 8 week intervals). The follow-up period was 48 weeks. Best-corrected visual acuity (BCVA) and central retinal thickness (CRT) were measured using Early Treatment Diabetic Retinopathy Study (ETDRS) charts and spectral-domain optical coherence tomography (OCT). The measurements were taken at the baseline and then at 16, 32, and 48 weeks.
Results: The treatment-naive group was composed of 135 eyes of 135 patients in the study. 61 eyes had Type 1 lesions of CNV, 50 eyes had Type 2 lesions, and 24 eyes had Type 4 lesions. Mean baseline BCVA ± SD for Type 1 lesions was 56.1 ± 10.8 ETDRS letters, and then 62.2 ± 12.9 letters, 61.2 ± 13.7 letters, and 62.8 ± 15.1 letters at 16, 32, and 48 weeks, respectively. Mean baseline CRT ± SD for Type 1 lesions was 442.4 ± 194.9 m, and then 302.5 ± 144.4 m, 299.7 ± 128.5 m, and 277.7 ± 106.5 m at 16, 32, and 48 weeks, respectively. Mean baseline BCVA ± SD for Type 2 lesions was 55.6 ± 9.9 ETDRS letters, and then 62.5 ± 11.1 letters, 60.7 ± 13.0 letters, and 62.5 ± 14.2 letters at 16, 32, and 48 weeks, respectively. Mean baseline CRT ± SD. For Type 4 lesions mean baseline BCVA ± SD was 56.7 ± 9.0 ETDRS letters, and then 59.1 ± 10.6 letters, 59.5 ± 11.4 letters, and 59.2 ± 12.6 letters at 16, 32, and 48 weeks respectively. Mean baseline CRT ± SD for Type 4 lesions was 492.1 ± 187.0 m, and then 333.3 ± 137.5 m, 354.4 ± 175.0 m, and 326.7 ± 122.4 m at 16, 32, and 48 weeks respectively. All these changes were statistically significant ( < 0.005).
Conclusions: The primary outcome of our study is that the treatment with aflibercept in nAMD patients led to statistically significant improvement in BCVA and to a decrease in CRT throughout the follow-up period in both occult and classic types of CNV. The minimally classic type of CNV demonstrated a poorer functional and anatomical response to treatment.

Background: Familial hypercholesterolemia (FH) is a genetically inherited disorder caused by monogenic mutations or polygenic deleterious variants. Patients with FH innate with significantly elevated risks for coronary heart disease (CHD). FH prevalence based on genetic testing in Chinese CHD patients is missing.

Poor understanding of the cellular and molecular basis of clinical and genetic heterogeneity in progressive multiple sclerosis (MS) has hindered the search for new effective therapies. To address this gap, we analyzed 632,000 single-nucleus RNA sequencing profiles from 156 brain tissue samples of MS and control donors to examine inter- and intra-donor heterogeneity. We found distinct cell type-specific gene expression changes between MS gray and white matter, highlighting clear pathology differences.

The present study aimed to examine the impact of Ricinus communis and valacyclovir (VACV) on the progression of skin lesions and pain responses in mice infected with herpes simplex virus type 1 (HSV-1). Mice were infected with HSV-1 and treated with R. communis (8, 16, or 48 mg/kg) or VACV (8, 25, or 90 mg/kg) twice daily on days 2-8 post-infection.

Background: The classification of major adverse cardiovascular event (MACE) endpoints in patients with type 2 diabetes mellitus (T2DM) and either confirmed coronary artery disease (CAD) or high CAD risk, as well as the extent of the association between T2DM and coronary plaque characteristics, remains uncertain.
Purpose: This meta-analysis aims to compare MACE endpoints between patients with diabetes and patients without diabetes based on coronary artery plaques.
Methods: We searched studies from Web of Science, PubMed, Embase, and the Cochrane Library up until September 1, 2023.
