Summary
Hemodialysis patients show significant impairments in future memory (PM), specifically in event-based and time-based tasks. These findings suggest PM can help evaluate cognitive dysfunction in hemodialysis patients.
Area of Science:
- Neuroscience
- Nephrology
- Cognitive Psychology
Background:
- Future memory (PM) is crucial for daily functioning.
- Cognitive function in hemodialysis (HD) patients requires thorough evaluation.
Purpose of the Study:
- To investigate future memory (PM) impairment in hemodialysis (HD) patients.
- To explore factors influencing PM task performance in HD patients.
Main Methods:
- Sixty HD patients and 60 age-matched healthy controls were assessed.
- Cognitive functions were evaluated using the MMSE, DST, VFT, RAVLT, SCWT, and PM tasks (EBPM and TBPM).
Main Results:
- HD patients demonstrated significantly worse performance on the MMSE, RAVLT (total recall, delayed recognition), SCWT (reading, color naming, interference, inhibition/switching), VFT (fruit), EBPM, and TBPM tasks compared to controls.
- No significant differences were observed in DST-Forward, DST-Backward, RAVLT delayed recall, or VFT (animals) between groups.
Conclusions:
- Event-based PM (EBPM) and time-based PM (TBPM) are impaired in hemodialysis patients.
- PM tasks show potential as tools for assessing cognitive dysfunction in HD patients.

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

764
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...
