Emergency Department Use Among Adults Receiving Dialysis.

Importance: People with kidney failure receiving maintenance dialysis visit the emergency department (ED) 3 times per year on average, which is 3- to 8-fold more often than the general population. Little is known about the factors that contribute to potentially preventable ED use in this population.

Objective: To identify the clinical and sociodemographic factors associated with potentially preventable ED use among patients receiving maintenance dialysis.

Global variations in funding and use of hemodialysis accesses: an international report using the ISN Global Kidney Health Atlas.

Background: There is a lack of contemporary data describing global variations in vascular access for hemodialysis (HD). We used the third iteration of the International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA) to highlight differences in funding and availability of hemodialysis accesses used for initiating HD across world regions.

Methods: Survey questions were directed at understanding the funding modules for obtaining vascular access and types of accesses used to initiate dialysis.

Randomized Controlled Trial of the Effect of an Exercise Rehabilitation Program on Symptom Burden in Maintenance Hemodialysis: A Clinical Research Protocol.

Background: People receiving hemodialysis experience high symptom burden that contributes to low functional status and poor health-related quality of life. Management of symptoms is a priority for individuals receiving hemodialysis but limited effective treatments exist. There is emerging evidence that exercise programming can improve several common dialysis-related symptoms.

The Association Between Intradialytic Symptom Clusters and Recovery Time in Patients Undergoing Maintenance Hemodialysis: An Exploratory Analysis.

Background: Individuals receiving hemodialysis often experience concurrent symptoms during treatment and frequently report feeling unwell after dialysis. The degree to which intradialytic symptoms are related, and which specific symptoms may impair health-related quality of life (HRQoL) is uncertain.

Objectives: To explore intradialytic symptoms clusters, and the relationship between intradialytic symptom clusters with dialysis treatment recovery time and HRQoL.

Nurse Practitioner Care Compared with Primary Care or Nephrologist Care in Early CKD.

Background: Early interventions in CKD have been shown to improve health outcomes; however, gaps in access to nephrology care remain common. Nurse practitioners can improve access to care; however, the quality and outcomes of nurse practitioner care for CKD are uncertain.

Methods: In this propensity score-matched cohort study, patients with CKD meeting criteria for nurse practitioner care were matched 1:1 on their propensity scores for ( 1 ) nurse practitioner care versus primary care alone and ( 2 ) nurse practitioner versus nephrologist care.

Health related quality of life during dialysis modality transitions: a qualitative study.

Background: Modality transitions represent a period of significant change that can impact health related quality of life (HRQoL). We explored the HRQoL of adults transitioning to new or different dialysis modalities.

Methods: We recruited eligible adults (≥ 18) transitioning to dialysis from pre-dialysis or undertaking a dialysis modality change between July and September 2017.

Electronic patient-reported outcomes in clinical kidney practice (ePRO Kidney): a process evaluation of educational support for clinicians.

Background: Patient-reported outcomes (PROs) are increasingly mandated in kidney care to incorporate patients' perspectives.

Objectives: We assessed whether educational support for clinicians using electronic (e)PROs could enhance person-centered care.

Design: A process evaluation, using a mixed methods longitudinal comparative concurrent design was undertaken of educational support to clinicians on routine use of ePROs.

Association Between the Route of Administration and Formulation of Estrogen Therapy and Hypertension Risk in Postmenopausal Women: A Prospective Population-Based Study.

Background: Hypertension is the leading global cause of cardiovascular disease and premature mortality in women. The effects of postmenopausal hormone therapy (HT) on blood pressure are uncertain but may be related to route of estrogen administration and formulation of estrogen. We sought to determine the association between route of administration and formulation of estrogen HT and hypertension risk in postmenopausal women.

A Randomized Trial Examining the Impact of Timing of Intradialytic Cycling on Intradialytic Hypotension.

Introduction: Intradialytic cycling is often performed during the first half of hemodialysis because of concerns regarding increased frequency of intradialytic hypotension (IDH) late in hemodialysis. This increases exercise program resource needs and limits utility of intradialytic cycling to treat dialysis-related symptoms.

Methods: This multicenter, randomized, crossover trial compared IDH rate when cycling during the first half versus the second half of hemodialysis in 98 adults on maintenance hemodialysis.

Sex differences in body fluid composition in humans with obstructive sleep apnea before and after CPAP therapy.

Obstructive sleep apnea (OSA) is common in heart and kidney disease, both conditions prone to fluid retention. Nocturnal rostral fluid shift contributes to the pathogenesis of OSA in men more than women, suggesting a potential role for sex differences in body fluid composition in the pathogenesis of OSA, with men having a predisposition to more severe OSA due to an underlying volume expanded state. Continuous positive airway pressure (CPAP) increases intraluminal pressure in the upper airway and mitigates the rostral fluid shift; this, in turn, may prevent fluid redistribution from other parts of the body to the upper airway.

Sex differences in COVID-19 symptoms and outcomes in people with kidney failure treated with dialysis: a prospective cohort study.

Background: People with kidney failure treated with dialysis are at increased risk of SARS-CoV-2 infection, and severe COVID-19 outcomes such as hospitalization and death. Though there are well-defined sex differences in outcomes for the general population with COVID-19, we do not know whether this translates into kidney failure populations. We aimed to estimate the differences in COVID-19 symptoms and clinical outcomes between males and females treated with maintenance dialysis.

The Association Between Route of Post-menopausal Estrogen Administration and Blood Pressure and Arterial Stiffness in Community-Dwelling Women.

Background: Postmenopausal hormone therapy (HT) is associated with increased cardiovascular risk. Although the route of estrogen administration may play a role in mediating risk, previous studies have not controlled for concomitant progestin use.

Objective: To investigate the association between the route of estrogen therapy (oral or non-oral) HT use, without concomitant progestin, and blood pressure and arterial stiffness in postmenopausal women.

Sex influences the effect of adiposity on arterial stiffness and renin-angiotensin aldosterone system activity in young adults.

Introduction: Sex influences the cardiovascular risk associated with body mass index (BMI) in older adults. Whether this risk differs by sex in younger adults is unknown. We aimed to evaluate the association between measures of adiposity and arterial stiffness and reninangiotensin-aldosterone system (RAAS) activity in younger adults, stratified by sex.

Canadian Association of Paediatric Nephrologists COVID-19 Rapid Response: Home and In-Center Dialysis Guidance.

Purpose Of The Program: This article provides guidance on optimizing the management of pediatric patients with end-stage kidney disease (ESKD) who will be or are being treated with any form of home or in-center dialysis during the COVID-19 pandemic. The goals are to provide the best possible care for pediatric patients with ESKD during the pandemic and ensure the health care team's safety.

Addressing feasibility challenges to delivering intradialytic exercise interventions: a theory-informed qualitative study.

Background: Intradialytic exercise (IDE) may improve physical function and health-related quality of life. However, incorporating IDE into standard hemodialysis care has been slow due to feasibility challenges. We conducted a multicenter qualitative feasibility study to identify potential barriers and enablers to IDE and generate potential solutions to these factors.

Global Policy Barriers and Enablers to Exercise and Physical Activity in Kidney Care.

Objective: Impairment in physical function and physical performance leads to decreased independence and health-related quality of life in people living with chronic kidney disease and end-stage kidney disease. Physical activity and exercise in kidney care are not priorities in policy development. We aimed to identify global policy-related enablers, barriers, and strategies to increase exercise participation and physical activity behavior for people living with kidney disease.

Understanding Home Hemodialysis Patient Attrition: A Cohort Study.

Background: Home hemodialysis (HHD) offers a flexible, patient-centered modality for patients with kidney failure. Growth in HHD is achieved by increasing the number of patients starting HHD and reducing attrition with strategies to prevent the modifiable reasons for loss.

Objective: Our primary objective was to describe a Canadian HHD population in terms of technique failure and time to exit from HHD in order to understand reasons for exit.

In-center nocturnal hemodialysis improves health-related quality of life for patients with end-stage renal disease.

Background: Conventional in-center hemodialysis (HD) is associated with significant symptom burden and reduced health-related quality of life (HRQOL). The HRQOL effects of conversion to in-center nocturnal hemodialysis (INHD) remain unclear, especially amongst those with poor HRQOL.

Methods: Prospective cohort study of HD patients converting to INHD.

Sex differences in the vascular access of hemodialysis patients: a cohort study.

Background: We describe differences for probability of receiving a fistula attempt, achieving fistula use, remaining catheter-free and the rate of access-related procedures as a function of sex.

Methods: Prospectively collected vascular access data on incident dialysis patients from five Canadian programs using the Dialysis Measurement Analysis and Reporting System to determine differences in fistula-related outcomes between women and men. The probability of receiving a fistula attempt and the probability of fistula use were determined using binary logistic regression.
