Abstract
The incidence and prevalence of end-stage kidney disease (ESKD) in Korea are increasing, and ESKD constitutes a very important medical and social issue. Elderly dialysis patients have the highest risk of early mortality within 3 months after initiating dialysis, and geriatric syndromes such as aging, frailty, functional impairment, and cognitive impairment are crucial for the prognosis of elderly patients. Shared decision-making (SDM) is an approach through which clinicians and patients can achieve informed preferences, thereby yielding better clinical outcomes and quality of life. Through SDM-based, close consultation among patients, families, and healthcare providers, an ESKD Life-Plan for elderly patients should be established. A multidisciplinary approach led by nephrologists can help them to provide proper vascular access for dialysis at the right time, with the right evidence, and to the right patient. Strategies that can improve peritoneal dialysis in elderly patients include assisted peritoneal dialysis, homecare support programs, and automated peritoneal dialysis. In order to enhance the role of kidney transplantation in elderly patients with ESKD, it is necessary to accurately identify patients' clinical conditions before transplantation and to perform active rehabilitation activities and postoperative management to promote recovery after transplantation. With the aging population and the increase in ESKD in the elderly, clinicians must identify factors affecting the mortality and quality of life of elderly dialysis patients.

Abstract
In this review, we discuss common challenges at the interface between dialysis access planning, prognostication, and patient-centered decision making. Particularly for patients whose survival benefit from dialysis is attenuated by advanced age or other serious illness, knowing the potential complications and anticipated frequency of access procedures is essential for patients and families to be able to conceptualize what life on dialysis will look like. Although starting dialysis with a functioning graft or fistula is associated with reduced infection rates, mortality, hospitalizations, and cost compared with a central venous catheter, these benefits must be weighed against the chance that early access placement in an elderly or seriously ill patient is an unnecessary surgery because the chronic kidney disease never progresses, the patient dies before developing an indication to start dialysis, or, the patient prefers conservative kidney management over dialysis. Kidney palliative care is a growing subspecialty of nephrology focused on helping seriously ill patients navigate complex medical decisions, and may be useful for intensive goals-of-care discussions about treatment and access options for patients with limited anticipated survival because of age or other serious illness.

Northrup H, He Y, Le H, Berceli SA, Cheung AK, Shiu YT. Differential hemodynamics between arteriovenous fistulas with or without intervention before successful use. Front Cardiovasc Med 2022; 9:1001267. [PMID: 36407418 PMCID: PMC9669082 DOI: 10.3389/fcvm.2022.1001267] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2022] [Accepted: 10/17/2022] [Indexed: 08/22/2023] Open
Abstract
A significant number of arteriovenous fistulas (AVFs) fail to maturate for dialysis. Although interventions promote maturation, functional primary patency loss is higher for AVFs with interventions (assisted maturation) than AVFs without interventions (un-assisted maturation). Although blood flow-associated hemodynamics have long been proposed to affect AVF remodeling, the optimal hemodynamic parameters for un-assisted maturation are unclear. Additionally, AVF maturation progress is generally not investigated until 6 weeks after AVF creation, and the examination is focused on the AVF's venous limb. In this exploratory study, patients (n = 6) underwent magnetic resonance imaging (MRI) at 1 day, 6 weeks, and 6 months after AVF creation surgery. Before successful use for hemodialysis, three AVFs required intervention and three did not. MRI of the AVFs were used to calculate lumen cross-sectional area (CSA) and perform computational fluid dynamics (CFD) to analyze hemodynamics, including velocity, wall shear stress (WSS), and vorticity. For the venous limb, the no-intervention group and intervention group had similar pre-surgery vein diameter and 1-day post-surgery venous CSA. However, the no-intervention group had statistically larger 1-day venous velocity (0.97 ± 0.67 m/s; mean ± SD), WSS (333 ± 336 dyne/cm2) and vorticity (1709 ± 1290 1/s) than the intervention group (velocity = 0.23 ± 0.10 m/s; WSS = 49 ± 40 dyne/cm2; vorticity = 493.1 ± 227 1/s) (P < 0.05). At 6 months, the no-intervention group had statistically larger venous CSA (43.5 ± 27.4 mm2) than the intervention group (15.1 ± 6.2 mm2) (P < 0.05). Regarding the arterial limb, no-intervention AVF arteries also had statistically larger 1-day velocity (1.17 ± 1.0 m/s), WSS (340 ± 423 dyne/cm2), vorticity (1787 ± 1694 1/s), and 6-month CSA (22.6 ± 22.7 mm2) than the intervention group (velocity = 0.64 ± 0.36 m/s; WSS = 104 ± 116 dyne/cm2, P < 0.05; vorticity = 867 ± 4551/s; CSA = 10.7 ± 6.0 mm2, P < 0.05). Larger venous velocity, WSS, and vorticity immediately after AVF creation surgery may be important for later lumen enlargement and AVF maturation, with the potential to be used as a tool to help diagnose poor AVF maturation earlier. However, future studies using a larger cohort are needed to validate this finding and determine cut off values, if any.
