Utilization of Instagram by Ophthalmology Residency Programs in the Era of COVID-19.

Purpose: The aim of this research is to describe the use of the social media platform, Instagram, by academic ophthalmology residency programs in the United States over time and consider the impact of the COVID-19 pandemic on ophthalmology's social media presence. Methods and Subjects: This cross-sectional study was conducted online by reviewing the publicly accessible Instagram accounts of all accredited US academic ophthalmology residency programs. Main Outcomes and Measures: Number of US ophthalmology residency programs with an affiliated Instagram account were analyzed by year of creation. The content of the top six accounts with the most followers was analyzed by evaluating amount of engagement within defined post categories. Results: Of the 124 ophthalmology residency programs, 78 (62.9%) were identified as having an affiliated Instagram account, 60 accounts (48.4%) were created during the years 2020 or 2021, and 62 (50.0%) accounts focused specifically on promoting the residency training program. Of the top six accounts with the most followers, post categories that received the most engagement were "Medical" and "Group Photo", while those that received the least engagement were "Department Bulletin" and "Miscellaneous." User engagement on posts as measured by likes and comments increased across multiple post categories after January 2020. Conclusion: Social media presence of ophthalmology residency programs on Instagram increased substantially in 2020 and 2021. As a result of the COVID-19 pandemic restricting in-person interactions, residency programs have used alternative platforms to reach applicants. Given the increasing use of such applications, social media will likely continue to become an important aspect of professional engagement in ophthalmology.

Rapid tissue prototyping with micro-organospheres.

In vitro tissue models hold great promise for modeling diseases and drug responses. Here, we used emulsion microfluidics to form micro-organospheres (MOSs), which are droplet-encapsulated miniature three-dimensional (3D) tissue models that can be established rapidly from patient tissues or cells. MOSs retain key biological features and responses to chemo-, targeted, and radiation therapies compared with organoids. The small size and large surface-to-volume ratio of MOSs enable various applications including quantitative assessment of nutrient dependence, pathogen-host interaction for anti-viral drug screening, and a rapid potency assay for chimeric antigen receptor (CAR)-T therapy. An automated MOS imaging pipeline combined with machine learning overcomes plating variation, distinguishes tumorspheres from stroma, differentiates cytostatic versus cytotoxic drug effects, and captures resistant clones and heterogeneity in drug response. This pipeline is capable of robust assessments of drug response at individual-tumorsphere resolution and provides a rapid and high-throughput therapeutic profiling platform for precision medicine.

Encephalopathy With Akinetic Mutism in a Child With COVID-19 Infection: A Case Report.

INTRODUCTION: COVID-19 has been associated with neurological complications, including encephalopathy and akinetic mutism. CASE PRESENTATION: A 7-year-old unvaccinated boy presented with visual hallucinations, urinary incontinence, and akinetic mutism 13 days after he was exposed to COVID-19. He had minimal respiratory symptoms, including just 1 day of fever and cough. Evaluations showed slowing on electroencephalogram, normal cerebrospinal fluid, normal brain magnetic resonance imaging, and mild sinus bradycardia. He recovered rapidly to baseline after 5 days of intravenous methylprednisolone. DISCUSSION: COVID-19-related encephalopathy including akinetic mutism is usually found in older adult patients with more severe COVID-19 illness. Our case demonstrates that akinetic mutism can present in children with mild COVID-19 illness and that it can respond rapidly and completely to intravenous methylprednisolone. CONCLUSIONS: COVID-19-related encephalopathy may be immune mediated. A heightened awareness of its association with COVID-19 illness should lead to earlier diagnosis and consideration of immunomodulatory therapy.

Cataracts in setting of multisystem inflammation after COVID-19 vaccination.

Purpose: To describe a unique case of bilateral cataract formation in the setting of multisystem inflammation after the 1st dose of the BNT162b2 mRNA COVID-19 vaccination. Observations: A previously healthy 20-year-old male developed intumescent bilateral cataracts leading to visual decline from 20/20 to 20/300-20/400 in each eye, likely from systemic inflammation after vaccination. Conclusion and importance: This is the first reported case of cataract formation following a COVID-19 vaccine. While ocular adverse effects associated with COVID-19 vaccination are rare, it is important to raise awareness of these entities amongst medical providers as the COVID-19 pandemic continues and vaccinations become widespread.
