Article Abstract

Aims: To analyze the impact of the COVID-19 pandemic on the activity and outcomes of the Andalusian Program for Early Detection of Diabetic Retinopathy (APDR).

Methods: A retrospective observational study was conducted during 2018-2023. The following variables were analyzed annually: newly included patients, retinal photographs performed, and pathological findings categorized by severity. Moderate-to-severe non-proliferative and proliferative retinopathy were classified as vision-threatening diabetic retinopathy (VTDR).

Results: In 2020 and 2021, the number of newly included patients (11,897 and 18,343, respectively) and retinal photographs performed (39,667 and 64,092, respectively) decreased compared to previous years (2018 and 2019: 25,940 and 30,807 new patients, respectively; 85,171 and 100,849 retinal photographs, respectively). In 2022, activity levels increased 160% compared to 2019. The proportion of VTDR cases remained stable at 0.163%, 0.14%, and 0.075% during 2021, 2022, and 2023, respectively, compared to the prepandemic period (0.168% and 0.117% in 2018 and 2019, respectively).

Conclusions: Despite the slowdown in activity during the COVID-19 pandemic, the post-pandemic proportion of VTDR cases diagnosed through the APDR remained stable, suggesting resilience against severe outcomes despite healthcare disruption. The program has demonstrated an effective recovery. Ongoing long-term monitoring is essential to fully assess the pandemic's potential impact on late-stage complications.

Background: The COVID-19 pandemic forced the world to quarantine to slow the rate of transmission, causing communities to transition into virtual spaces. Asian American and Pacific Islander communities faced the additional challenge of discrimination that stemmed from racist and xenophobic rhetoric in the media. Limited data exist on technology use among Asian American and Pacific Islander adults during the height of the COVID-19 shelter-in-place period and its effect on their physical and mental health.

The COVID-19 pandemic, caused by the continuously evolving SARS-CoV-2 virus, has presented persistent global health challenges. As novel variants emerge, many with enhanced transmissibility and immune evasion capabilities, concerns have intensified regarding the efficacy of existing vaccines and therapeutics. This review provides a comprehensive overview of the current landscape of COVID-19 vaccination, including the development and performance of monovalent and bivalent boosters, and examines their effectiveness against newly emerging variants of interest (VOIs) and variants under monitoring (VUMs), such as JN.

This article explores two complementary strategies for addressing the affordability and access challenges facing advanced therapies. As high development costs and limited market access have led to the withdrawal of several therapies, the article examines how these barriers create 'valleys of death' that prevent innovation from reaching patients. Through the case of Glybera and other examples, it outlines a rehabilitative approach focused on reforming current systems through improved reimbursement schemes, regulatory streamlining, and more efficient manufacturing.
