“…Because older male COVID-19 patients have a poorer prognosis, as compared to young females [ 3 , 40 , 41 ], and given the large size of our cohorts, we tried identifying metabolic and clinical correlates for these variables ( Figure 3 A–D, Supplementary Figures S4E–J and S5 ). Aging was associated with increased weight, BMI, kidney dysfunction (creatine, creatinine), and tissue damage (creatine kinase), along with markers of hypercoagulability (VWF:AG, FVIII), fibrinolysis (D-dimer), hyperglycemia, hypoxia and mitochondrial dysfunction (2-hydroxyglutarate, lactate, spermidine, acylcarnitines), purine oxidation (urate), inflammation (CRP), proteolysis (albumin), and anemia (hemoglobin levels, RBC counts), especially in COVID-19 patients ( Figure 3 A–D).…”
