Survival and cognitive deterioration in elderly patients undergoing hemodialysis.

Aim: This study aimed to elucidate the 5-year changes in the cognitive function of elderly patients undergoing hemodialysis and its association with survival and related factors.

Methods: Cognitive function in patients aged ≥65 years undergoing hemodialysis at the Nagasaki Renal Center was assessed using the Mini-Mental State Examination (MMSE) in 2016. Patients were subsequently classified into normal, mild cognitive impairment (MCI) and suspected dementia groups according to their scores; MMSE was conducted at 30 and 60 months thereafter.

Poor prognosis after lower-limb amputation irrespective of diabetes status in patients undergoing hemodialysis.

Introduction: Diabetes mellitus is one of the most important risk factors for lower-limb amputation in patients undergoing hemodialysis. However, the influence of diabetes mellitus on survival after lower-limb amputation is unknown.

Methods: Patients who underwent lower-limb amputation since 1996 (amputation group) and those who underwent hemodialysis during 2011-2012 (control group) were included and were followed up until July 2022.
