Effect of COVID-19 on Alzheimer's and dementia measured through ocular indications

Screening for early detection of Alzheimer's disease (AD) through a comprehensive eye exam appears to be promising and could potentially provide a more sensitive, inexpensive way to visualize early signs of AD for early detection in large populations. Optical coherence tomography (OCT), as well as retinal imaging techniques such as Doppler and fluorescence lifetime imaging ophthalmoscopy (FLIO), can detect signs of early AD such as vascular changes or accumulations of Tau proteins and beta-amyloid proteins. In the age of COVID-19, this screening opportunity is threatened by increased no-show rates leading to decreased early detection of AD. Through the combination of COVID-19 neuroinflammation potentially augmenting AD neurodegeneration, as well as missed opportunity in the use of early ophthalmic detection, the pandemic may have significantly worsened the trajectory of AD. © 2023 Elsevier Inc.

Primary ureteroscopy for diagnosing and treating acute urolithiasis during the COVID-19 pandemic: Quality and cost benefits

Purpose: The purpose of this study was to investigate the management of acute urolithiasis during index admission by primary ureteroscopy (P-URS) during coronavirus disease-2019 (COVID-19) pandemic. With the rise in prevalence of urolithiasis, the focus has shifted to manage patients presenting with acute ureteric colic during their first admission rather than using temporary measures such as emergency stenting (ES) or nephrostomies which are followed by deferred ureteroscopic procedures Deferred Ureteroscopy (D-URS). We compared the results of ES with P-URS procedures in terms of quality and cost benefits during COVID-19 pandemic. Materials and Methods: Data were collected prospectively from April 2020 to March 2021 for all emergency urolithiasis procedures performed including ES and P-URS. The quality assessment was based in relation to patient factors including the number of procedures per patient, number of days spent at hospital, number of days off work, and expertise of person operating. Cost analysis included theater expenses, hospital stay charges, and loss of working days. Results: This study revealed that the average stay of patients on index admission who had an ES was 1.35 days compared to 1.78 days in patients who underwent P-URS. Patients who had ES had to undergo D-URS and spent another average of 1.5 days in the hospital. Overall, additional expenditure in patients who did not undergo primary ureterorenoscopy was on an average in the range of £1800 (excluding loss of work for patients, who needed to return for multiple procedures). Conclusion: We conclude that the approach of P-URS and management of stones in index admission is very effective in both improving quality of patients (during the COVID-19 pandemic) and bringing down cost expenditure effectively.
