Hyaline vs atheromatous lesions / Membranous & Focal Segmental nephropathy

There are these little things that UW is confusing me with. UW mentioned in one explanation that hyaline "acellular" arteriolosclerosis is a result of mild hypertension (the common essential hypertension), but in another explanation it says it's a result of diabetic microangiopathy, while only atheromatous lesions (lipid-filled plaques) are due to hypertension and causes claudication.

Another thing, UW says that focal segmental nephropathy is the most common cause of nephrotic syndrome in adults, while in FA, membranous nephropathy is the most common culprit.

So.. what really is the correct info?
