The Intact Nephron Hypothesis has guided renal drug dosing for 60+ years. The idea: as GFR drops, tubular secretion drops proportionally. Sounds elegant, right? But new data shows it's WRONG for many drugs in severe CKD. Here's what you need to know 🧵👇 #Nephrology #NephSky #Pharmacokinetics

Normal anion gap metabolic acidosis + positive urine anion gap = RENAL TUBULAR ACIDOSIS But which type? Proximal vs distal?🤔 Key findings that pointed to DISTAL RTA: ✅ Severe hypo-K ✅ Urine pH >5.5 despite systemic acidosis ✅ NO Fanconi syndrome features www.kireportscommunity.org/post/renal-t...

Next level of cherry-picking. Lack of significance in Student's t-test? Report then F-test and interpret it as a t-test 🫣🫣🫣 (F-test compares variances, not means🤡) Source: doi.org/10.3390/cell...

Sometimes it’s not about finding a disease marker — it’s about noticing what’s missing. In some cases, a healthy, stable microbiome is the best sign of health. When that pattern breaks, disease can follow. doi.org/10.1101/2023...

2/4 Pathophysiology: RHUC = mutations in proximal tubule UA transporters → impaired reabsorption → UA loss in urine. It can lead to exercise-induced AKI (EIAKI). To make life harder, during EIAKI, UA may normalize. (Figure from www.mdpi.com/2227-9059/10...)

A great surprise to start the day—thank you, @wikipedia.org, for the recognition! 🥰
