Abstract
Background & Aim: One of the important issues that affects the quality of hemodialysis is recirculation. Some researchers have suggested that the direction and distance of needle cannulation can affect the amount of recirculation. Therefore, this study aimed to investigate the effect of direction and distance of needle cannulation on recirculating of arteriovenous fistula in hemodialysis patients.
Methods & Materials: This clinical trial was performed on patients referred to the dialysis ward of Kamkar-Arabnia hospital affiliated to Qom University of Medical Sciences in 2016. The amount of recirculation was measured in 22 patients by urea based method, in four consecutive sessions. In each session, the distance and direction of the needles were three centimeters in opposite direction, three centimeters in same direction, six centimeters in opposite direction, and six centimeters in same direction. Data were analyzed using Stata and GEE test.
Results: The average age of participants was 53(16±0.75) years. In 41 dialysis cases (out of 88), the amount of recirculation was higher than 10%. The odds ratio for more than 10% recirculation for a distance of three centimeters compared to six centimeters was 2.05 (1.07-3.93) and for same direction compared to opposite direction was 1.98 (1.03-3.78).
Conclusion: The results of this study showed that the insertion of needles at a distance of six centimeters in opposite position had the lowest chance of recirculation. Therefore, the attention to proper insertion of needles can be effective in reducing recirculation and increasing the quality of dialysis.

Abstract
Background & Aim: Occupational fatigue reduces the quality-of-life of healthcare workers. Warm foot baths have been suggested as a simple, traditional intervention for prevention and management. The present study aimed to investigate the effect of warm foot baths on occupational fatigue and quality of life among intensive care unit (ICU) nurses.
Methods & Materials: A randomized controlled trial was conducted with 50 ICU nurses at Shahid Beheshti Hospital, Qom, in 2023. Participants were recruited by convenience sampling and randomly assigned to an intervention or a control group. The intervention consisted of immersing the legs below the knees in warm water for 15 minutes each night for two weeks. The control group received no intervention. The Swedish Occupational Fatigue Inventory (SOFI) and a quality-of-life questionnaire were completed at baseline and after the intervention. Data were analyzed using chi-square tests and t-tests in SPSS version 22.
Results: The total fatigue score (P=0.014) and the physical discomfort subscale (P=0.012) showed significantly greater reductions in the intervention group compared to the control group. No significant differences were observed in other fatigue subscales. Changes in quality of life and its subscales did not differ significantly between groups.
Conclusion: The findings indicate that warm foot baths effectively reduce occupational fatigue among ICU nurses. Therefore, the use of warm foot baths is recommended as an affordable, easy, and fast-acting solution to alleviate nurses' fatigue.
