Article Abstract
Purpose: To determine the loss of follow-up ratio and reasons during the COVID-19 lockdown in patients with retinal diseases treated by anti-vascular endothelial growth factor intravitreal injections and to report the visual outcome and rate of complications of these patients 1 year after the end of the lockdown.
Methods: This is a prospective descriptive cohort study (NCT04395859) conducted at the Rothschild Foundation Hospital - Paris between April 2020 and May 2021. Patients with retinal diseases treated by repeated intravitreal anti-VEGF injections (IVI) since before October 2019 were included. They filled-out a questionnaire and were followed up during a period of 1 year.
Results: During the COVID-19 lockdown 198 eyes (82.5%) of 157 patients (82.6%) received their injections in a timely manner (group 1) while 42 eyes (17.5%) of 33 patients (17.4%) had their injections delayed or missed (group 2). No statistically significant difference was found between group 1 and group 2 when comparing the change of mean best corrected distance visual acuity (BCVA) between month 12 and inclusion ( = 0.6) and the rate of ocular complications. The most frequent reasons for missing scheduled injections are appointments cancellation by the hospital (12 patients, 36%), fear of virus exposure during transportation (7 patients, 21%) or at the hospital (5 patients, 15%). Eighty-four percent (130/157 patients) of patients who attended their appointment were satisfied by the protective measures used in the hospital.
Conclusion: COVID-19 lockdown did not seem to negatively affect the 1-year outcome of patients with retinal diseases treated by anti-VEGF IVIs who missed their scheduled injections. The BCVA and rate of complications at 1 year did not differ whether patients missed their scheduled injections or not. Maintaining IVIs during lockdown periods and educating patients about the risks of missing injections are pivotal in improving prognosis of retinal diseases.

The study also evaluated changes in critical treatment intervals: onset to door (O2D), door to balloon (D2B) and door to needle (D2N) and assessed 30-day clinical outcomes. This study examined MI care trends in India during the COVID-19 lockdown period, irrespective of patients' COVID-19 infection status.

Understanding dog behavior, especially in the context of the human social environment, is critical to maintaining positive human-dog interactions and relationships. Furthermore, behavior can be an important indicator of health and welfare in companion dogs. Behavioral change can signal transitions in life stages, alert caretakers to potential illnesses or injuries, and is an important factor in understanding and measuring stress.

Background: Extended delays in non-elective surgeries have been associated with suboptimal outcomes. The SARS-CoV-2 pandemic forced healthcare systems to adapt their setups for unscheduled procedures, leading, in our institution, to a reorganization from a setup with two dedicated operating rooms (ORs) at a central facility without dedicated teams to a temporary one with both dedicated teams and ORs during lockdown phase. This study evaluates the impact of this transitions on the time to surgery considering unscheduled procedures.

Objective: There is a lack of research on how illness representations as represented in the Common Sense Self-Regulation Model (CS-SRM) emerge and develop. We aimed to describe the evolution of COVID-19 illness representations over time, and to explore associations with sociodemographic characteristics and protective behaviours.
Methods And Measures: This study (June 2020 release from lockdown to February 2021 after vaccine roll-out) used 17 independently recruited cross-sectional cohorts.
