Abortion is one of the major threats to the livestock industry, and it also poses significant threats to public health since some of the abortifacient agents are considered zoonotic. (), (), (), and Cache Valley virus (CVV) are recognized as important zoonotic and abortifacient agents of reproductive failure in small ruminants. This study determined the prevalence of these agents in ovine and caprine foetuses in Türkiye.

Studies have speculated that it may ultimately affect the choroidal anatomy. This is particularly important from a clinical point-of-view since patients occasionally hold their breath while undergoing macular optical coherence tomography (OCT).

This study aimed to investigate the prevalence and genetic diversity of DWV in honey bees in Türkiye and to determine the role of in the transmission of the genetic variants of DWV. Honey bee samples were collected from 62 apiaries, by simple random sampling, during March 2022 and April 2023.
View Article and Find Full Text PDFObjective: To compare one-year anatomical and functional results of switching to an on-label intravitreal anti-vascular endothelial growth factor (anti-VEGF) agent (intravitreal ranibizumab [IVR] or aflibercept [IVA]) after treatment failure with three loading doses of off-label intravitreal bevacizumab (IVB), which is mandatory in the treatment of neovascular age-related macular degeneration (nAMD) to get reimbursement from Social Security Institution in Turkiye.
Methods: This comparative, real-life, retrospective cohort study included treatment-naïve nAMD patients treated starting with three loading doses of IVB, switched to three loading doses of IVR and IVA due to treatment failure after IVB loading, and followed up one year with a treat-and-extend (T&E) protocol with 2-week extension/shortening intervals. The primary outcomes were changes in best-corrected visual acuity (BCVA; logMAR) and central macular thickness (CMT, µm) one year after the switch, and the secondary outcomes were maximum treatment intervals, number of injections, and disease activity rates.
Article Synopsis
- The study aimed to evaluate the choroidal blood vessel structure in pediatric myopic patients, specifically analyzing those with and without peripapillary hyperreflective ovoid mass-like structures (PHOMS).
- A total of 60 myopic patients were assessed, along with a control group of 30 emmetropic children, using advanced imaging techniques to measure various choroidal parameters such as total choroidal area and vascularity index.
- Results showed significant differences in choroidal metrics between patients with PHOMS and the control group, suggesting that choroidal characteristics vary in myopic children with these structures; however, more extensive research is needed to fully understand these differences.
