Abstract
BACKGROUND Patients with advanced chronic kidney disease have lower health-related quality of life (HRQOL) than the general population. There is uncertainty regarding patterns of HRQOL changes before dialysis initiation. This study aimed to characterise HRQOL trajectory and assess its potential association with intended dialysis modality. METHODS This prospective single-centre cohort study followed adults with an estimated glomerular filtration rate ≤15 mL/min/1.73 m2 for one year. Patients were allocated into one of two groups based on their intended treatment modality, 'home dialysis' (peritoneal dialysis or home haemodialysis (HD)) and 'other' (in-centre HD or conservative care). Follow-up was for up to 1 year or earlier if initiated on kidney replacement therapy or died. Kidney Disease Quality of Life - Short Form (KDQOL-SF) was completed every 6 months. Predictors of changes in KDQOL-SF components were modelled using mixed effect multivariable linear regressions. RESULTS One hundred and nine patients were included. At baseline, crude physical composite summary (PCS) (45 ± 10 vs. 39 ± 8) was higher in patients choosing home dialysis (n = 41), while mental composite summary (MCS) was similar in both groups. After adjustment, patients choosing home dialysis had an increase in MCS (B = 8.4 per year, p = 0.007) compared to those selecting in-centre HD/conservative care. This translates into an annual increase in MSC by 3 points for the 'home dialysis' group, compared to an annual decline by 5.4 points in the 'other' group. There was no difference in PCS trajectory through time. CONCLUSIONS Patients choosing home dialysis had improved MCS over time compared to those not selecting home dialysis. More work is needed to determine how differences in processes of care and/or unmeasured patient characteristics modulate this association.

Abstract
BACKGROUND It has been reported that living far from the peritoneal dialysis (PD) unit is a risk factor for peritonitis. Considering that PD units are urban located; the question of whether living in a rural area compared to an urban area is a risk factor for peritonitis has arisen. METHODS From March 2010 to August 2020, 335 episodes of peritonitis in 202 PD patients followed in a single center were evaluated retrospectively. People living in areas with a population <1000 were defined as living in rural areas regardless of their distance from the PD center. Cox regression analysis was used to identify independent factors associated with peritonitis. RESULTS A total of 202 PD patients were followed during 791 patient-years (mean follow-up of 3.9 years per patient). Total patients had 335 episodes of peritonitis and the rate of peritonitis was 0.42 episodes per year (episodes/patient-year). Cox regression analysis revealed that living environment (urban vs. rural) was not a risk factor for peritonitis (p = 0.57). CONCLUSIONS In Turkey, we report that living in a rural area in our region is not a risk factor for peritonitis. It is not the right approach for both the physician and the patient to be reluctant in the choice of PD due to the concern of peritonitis in rural areas.

Abstract
Key Points The adjustments made by the dialysis units during the peak of the pandemic were effective in maneuvering the challenges faced by our patients during the COVID-19 pandemic. Patients who remained on PD were satisfied with the quality of care, felt supported by the unit staff, and did not report feeling anxious or depressed. Background During the coronavirus disease 2019 (COVID-19) pandemic, adjustments were made to peritoneal dialysis (PD) practices in the outpatient units. These were decisions made by dialysis providers, clinical staff, and governments with input from patient organizations in some instances. The patient perspective regarding these changes during the pandemic has not been explored. We sought to evaluate patient experiences and perceptions of the challenges they faced, institutional adjustments, and their mental health during the height of the COVID-19 pandemic in the United States. Methods We conducted a cross-sectional survey of PD patients across four home dialysis units affiliated with four large academic centers, who were on PD between March 2020 and March 2021. Results Ninety-eight participants completed the survey across the four outpatient PD clinics. Over 95% of patients did not have to change their home accommodations during the pandemic, and over 80% did not have issues getting their dialysis supplies and medications delivered. Ninety-three percent of patients felt comfortable coming to the dialysis unit if they needed to during the pandemic. Almost all patients (98%) felt supported by their dialysis staff during the peak of COVID-19 and had modified Patient Health Questionnaire 2 (91%) and Generalized Anxiety Disorder 2-item (96%) scores not consistent with depression or anxiety. Less than 10% of patients considered changing their dialysis modality. Conclusions The adjustments made by the dialysis units during the peak of the pandemic were effective in maneuvering the challenges faced by our patients during the COVID-19 pandemic. Overall, patients who remained on PD were satisfied with the quality of care, felt supported by the unit staff, and did not report feeling anxious or depressed.

Abstract
The dialyzer is the core element in the hemodialysis treatment of patients with end-stage kidney disease (ESKD). During hemodialysis treatment, the dialyzer replaces the function of the kidney by removing small and middle-molecular weight uremic toxins, while retaining essential proteins. Meanwhile, a dialyzer should have the best possible hemocompatibility profile as the perpetuated contact of blood with artificial surfaces triggers complement activation, coagulation and immune cell activation, and even low-level activation repeated chronically over years may lead to undesired effects. During hemodialysis, the adsorption of plasma proteins to the dialyzer membrane leads to a formation of a secondary membrane, which can compromise both the uremic toxin removal and hemocompatibility of the dialyzer. Hydrophilic modifications of novel dialysis membranes have been shown to reduce protein adsorption, leading to better hemocompatibility profile and performance stability during dialysis treatments. This review article focuses on the importance of performance and hemocompatibility of dialysis membranes for the treatment of dialysis patients and summarizes recent studies on the impact of protein adsorption and hydrophilic modifications of membranes on these two core elements of a dialyzer.

Abstract
Background The availability of dialysis facilities and distance traveled to receive care can impact health outcomes for patients with newly onset kidney failure. We examined recent changes in county-level number of dialysis facilities between 2012 and 2019 and assessed the association between county-level dialysis facility supply and the distance incident kidney failure patients travel to receive care. Methods We conducted a cross-sectional study of 828,427 adult patients initiating in-center hemodialysis for incident kidney failure between January 1, 2012, and December 31, 2019. We calculated the annual county-level number of dialysis facilities, and counties were categorized as having zero, one, two, or three or more dialysis facilities at the time of treatment initiation. We then measured the distance traveled between a patient's home address and dialysis facility at treatment initiation (in miles) and evaluated the association between county-level number of dialysis facilities and distance traveled to initiate treatment. Results The average annual county-level number of facilities increased from 1.8 to 2.3 between 2012 and 2019. In our study period, 5% of incident adult kidney failure patients resided in a county that had zero dialysis facilities between 2012 and 2019. Compared with counties with three or more dialysis facilities, patients living in counties with no facilities in our study period traveled 14.3 miles (95% CI, 13.4 to 15.2) further for treatment. Conclusions Kidney failure patients in counties that had no dialysis facilities traveled further, limiting their access to dialysis. Counties with no dialysis facilities at the end of the study period were more rural and had higher poverty than other counties.

Abstract
To facilitate the desired increase in home dialysis utilization in the United States, multiple factors need to be taken into consideration in order to achieve this complex task. Through policy-level facilitators such as the Advancing American Kidney Health Initiative and the expansion of telehealth utilization, adjustments to the existing payment models, providing health equity incentives, increasing number of provider education materials on home therapies, and allaying patient fears with the expansion of home dialysis education nationwide, we have taken several steps in the right direction. There is still a long way to go, and further improvements can be made while utilizing lessons learned from some of our international peers who have been successful in their implementation of large-scale home dialysis programs.

Abstract
Background The 240,000 rural patients with end stage kidney disease in the United States have less access to nephrology care and higher mortality than those in urban settings. The Advancing American Kidney Health initiative aims to increase the use of home renal replacement therapy. Little is known about how rural patients access home dialysis and the availability and quality of rural dialysis facilities. Methods Incident dialysis patients in 2017 and their facilities were identified in the United States Renal Data System. Facility quality and service availability were analyzed with descriptive statistics. We assessed the availability of home dialysis methods, depending on rural versus urban counties, and then we used multivariate logistic regression to identify the likelihood of rural patients with home dialysis as their initial modality and the likelihood of rural patients changing to home dialysis within 90 days. Finally, we assessed mortality after dialysis initiation on the basis of patient home location. Results Of the 97,930 dialysis initiates, 15,310 (16%) were rural. Rural dialysis facilities were less likely to offer home dialysis (51% versus 54%, P<0.001). Although a greater proportion of rural patients (9% versus 8%, P<0.001) were on home dialysis, this was achieved by traveling to urban facilities to obtain home dialysis (OR=2.74, P<0.001). After adjusting for patient and facility factors, rural patients had a higher risk of mortality (HR=1.06, P=0.004). Conclusions Despite having fewer facilities that offer home dialysis, rural patients were more often on home dialysis methods because they traveled to urban facilities, representing an access gap. Even if rural patients accessed home dialysis at urban facilities, rural patients still suffered worse mortality. Future dialysis policy should address this access gap to improve care and overall mortality for rural patients.
