Coronavirus Disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Over 220 countries and territories have been affected by this virus, and the infection rate has continued to rise. As patients recover from the virus, many are experiencing lingering symptoms. Understanding the impact of demographics and comorbidities on symptom prevalence, manifestations, and severity is not only relevant during acute infection, it is critical to the clinical management of patients with post-acute sequelae of COVID-19, also known as PASC. Herein, we provide a comprehensive review on the most recent research related to PASC. Specifically, we focus on the description of the disorder itself, compared to acute COVID-19, and which types of patients are most affected by long-term sequelae. Further, we share recommendations for management of the most common complications of PASC.
Until additional studies are performed, the risks and benefits must be weighed on an individual basis with consideration of prophylaxis when a decision is made to continue these medications in the perioperative period. Part of this decision making includes the risk of fetal harm in an unwanted pregnancy in preparation for nonobstetric surgery versus an increased risk of venous thromboembolism.
ObjectiveThis study aims to investigate the effects of ankle joint mobilization (AJM) on mechanical hyperalgesia and peripheral and central inflammatory biomarkers after intraplantar (i.pl.) Complete Freund’s Adjuvant (CFA)-induced inflammation.MethodsMale Swiss mice were randomly assigned to 3 groups (n = 7): Saline/Sham, CFA/Sham, and CFA/AJM. Five AJM sessions were carried out at 6, 24, 48, 72, and 96 h after CFA injection. von Frey test was used to assess mechanical hyperalgesia. Tissues from paw skin, paw muscle and spinal cord were collected to measure pro-inflammatory (TNF, IL-1β) and anti-inflammatory cytokines (IL-4, IL-10, and TGF-β1) by ELISA. The macrophage phenotype at the inflammation site was evaluated by Western blotting assay using the Nitric Oxide Synthase 2 (NOS 2) and Arginase-1 immunocontent to identify M1 and M2 macrophages, respectively.ResultsOur results confirm a consistent analgesic effect of AJM following the second treatment session. AJM did not change cytokines levels at the inflammatory site, although it promoted a reduction in M2 macrophages. Also, there was a reduction in the levels of pro-inflammatory cytokines IL-1β and TNF in the spinal cord.ConclusionTaken together, the results confirm the anti-hyperalgesic effect of AJM and suggest a central neuroimmunomodulatory effect in a model of persistent inflammation targeting the pro-inflammatory cytokines IL-1β and TNF.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
