Long-Term Consequences of COVID-19 in Predominantly Immunonaive Patients: A Canadian Prospective Population-Based Study.

: Lingering symptoms are frequently reported after acute SARS-CoV-2 infection, a condition known as post-COVID-19 condition (PCC). The duration and severity of PCC in immunologically naïve persons remain unclear. Furthermore, the long-term consequences of these chronic symptoms on work and mental health are poorly documented.

Cardiac and pleuropulmonary involvement in Erdheim-Chester disease without bone lesions: A case report.

Erdheim-Chester disease is a rare multisystemic non-Langerhans histiocytosis characterized by histiocytes that stain positive for CD68 and negative for CD1a. Skeletal involvement is reported to be present in up to 96% cases and mutation in about half of the cases. Here, we report a patient with an unusual longstanding BRAF-negative Erdheim-Chester disease without bone lesions who developed pleuropulmonary and cardiac involvement.

Retinal Displacement: Providing New Insights for Retinal Detachment Surgery.

Purpose: To review the current literature on retinal displacement and provide a discussion of potential risk factors, postoperative outcomes, and future directions.

Methods: Two databases, MEDLINE and EMBASE, were mined using a directed search strategy to identify all articles on retinal displacement.

Results: We identified 1522 articles.

Effect of growth media and washing on the spectral signatures of aerosolized biological simulants.

We have evaluated the influence of growth media and washing on the laser-induced fluorescence spectra of bacteria. Three different bacterial simulants were cultured in three types of growth media. Three kinds of samples were generated from each culture: the culture itself, the growth medium alone, and a triple-washed sample.
