The Central Role of the Aldosterone in COVID-19 Provides a Treatment Target.
Bibliographic record
Abstract
Striking features of the COVID-19 pandemic are the rapid spread of the SARS-CoV-2 virus and the relatively narrow profile of patients adversely affected. SARS-CoV-2 enters human cells by means of ACE2, destroying the protein in the process. ACE2 maintains renin-angiotensin-aldosterone system (RAAS) homeostasis and is upregulated in the setting of chronic RAAS disequilibrium seen in COVID-19-susceptible patients. The ACE2-depletion effect on angiotensin II (AngII) levels likely contributes to the spectrum of cytokine responses found in COVID-19 patients. However, as most of the inflammatory effects of AngII are amplified through aldosterone-activated mineralocorticoid receptors (MRs), blocking MRs may provide much-needed benefit. The MR-blockers, spironolactone and eplerenone, are relatively selective in exerting downstream dampening effects on RAAS stress and target the pathophysiological processes in COVID-19-susceptible patients where acute viral-induced ACE2 depletion could be responsible for a catastrophic aldosterone surge in severely ill patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
