End stage kidney disease (ESKD) patients in the developing countries often present late for dialysis initiation with advanced uremia and life-threatening complications. Urgent start dialysis in such emergent situations exposes the patient to risk of uremia related complications as well as iatrogenic insults. We report the case of a middle-aged man with ESKD who presented late with acute pulmonary edema and hyperkalemia and developed osmotic demyelination syndrome following urgent start hemodialysis. Osmotic demyelination syndrome in this patient is noteworthy since there was no accompanying hyponatremia, the most commonly recognized antecedent. We propose that rapid lowering of serum osmolality by aggressive hemodialysis is sufficient to incite osmotic demyelination syndrome in patients who have long-standing uremia and high blood urea level. Malnutrition resulting from uremia might be a compounding factor in this scenario. Our patient had a characteristic initial presentation of osmotic demyelination syndrome with locked-in-state which later progressed to respiratory failure and death.

Introduction: It is unclear if cannulation-associated variables such as timing of first cannulation, access creation method, cannulation technique, or needle type are associated with the outcomes of arteriovenous fistulas. We conducted a meta-analysis to investigate such potential associations with 1-year primary patency.

Methods: Twenty-eight publications with titles that included "arteriovenous fistula," "patency," "cannulation," "metric," "first cannulation," "hemodialysis," "complication," "vascular," "nursing," and "puncture" were retrieved and reviewed.

Findings: The 1-year primary patency rates ranged from 0.32 to 0.93. Primary patency rates were significantly lower in patients in whom initial cannulation was done less than 1.5 months after fistula creation compared to fistulas first cannulated more than 1.5 months after anastomosis (odds ratio [OR] = 0.41, 95% confidence interval [CI]: 0.32-0.52). The effect of cannulation timing on primary patency rate was attenuated when plastic cannulas were used during the first two to three puncture weeks compared to metal needles (OR = 0.62 vs. 0.34; p = 0.032). Fistulas in the upper arm did not have a higher 1-year primary patency compared to those in the forearm (OR = 1.05, 95% CI: 0.93-1.19). Primary patency of upper arm arteriovenous fistulas was higher in reports from the Americas or Europe compared to reports from Asia. Buttonhole cannulation was not associated with higher patency rates at 1 year compared to rope-ladder cannulation (OR = 1.14, 95% CI: 0.75-1.71).

Discussion: Early cannulation was associated with reduced 1-year arteriovenous fistula patency. This association was reduced when plastic cannulas were used during the initial 2-3 weeks.

Introduction: Cognitive impairment is common among patients with hemodialysis. Hemodialysis patients have theoretical risks for both deficiency and accumulation of trace elements. We aimed to investigate the relationship between cognitive dysfunction and whole blood levels of trace elements in hemodialysis patients. We also aimed to examine the effect of baseline trace element status and cognitive dysfunction on mortality.

Methods: Maintenance hemodialysis patients and age-and sex-matched controls were included. The whole blood levels of trace elements were measured by inductively coupled plasma mass spectrometry. Cognitive impairment was defined as a score of ≤24 points on the Montreal Cognitive Assessment test. Executive dysfunction was also defined as Trails A score of more than 75 s and Trails B score of more than 180 s.

Findings: Forty-two patients and 35 controls were included. Cognitive impairment was detected in 69% of the patients and 45.7% of the controls (p = 0.039). Cognitively impaired patients had lower education years (p = 0.003) and higher whole blood levels of manganese (Mn) and lead (Pb) (p = 0.026, p = 0.019, respectively) compared to patients without cognitive impairment. Mn levels were also found statistically higher in patients with executive dysfunction compared to patients without executive dysfunction (p = 0.005). Lower education years and higher Pb levels were independent risk factors for cognitive impairment in hemodialysis patients (odds ratio [OR] 0.589 [95% confidence interval, CI 0.400-0.866, p = 0.007] and OR 1.047 [95% CI 1.001-1.096, p = 0.047, respectively]).

Discussion: Cognitive impairment, especially impaired executive function, is common among patients with hemodialysis patients. Cognitive impairment is not found to be associated in cross-sectional analysis with several modifiable end-stage renal disease- and dialysis-associated factors. The accumulation of trace elements especially Mn and Pb might exacerbate the cognitive dysfunction in hemodialysis patients.

Background: Healthcare-associated infections are still a worrying health problem that complicates patient care and increases morbidity and mortality. The incidence of infections in hemodialysis patients is still high and they constitute the second cause of hospitalization and death in this category.

Aims: The study's objective was to evaluate nursing and medical staff's involvement in hospital hygiene.

Methods: This is an observational study that took place within the hemodialysis unit of a Moroccan university hospital from March 2021 to June 2021. A surface swabbing technique for bacteriological examination was also carried out.

Results: The study revealed some shortcomings regarding hand hygiene which was respected by the nurses in only 17.5% of sessions and in 42.2% by the doctors. Other shortcomings in asepsis measures, were also noted such as the non-change of gloves after skin preparation (1.03%) and before manual compression. The serological status of patients concerning HBV, HVC, and HIV was also not always known (31.1%). The bacteriological samples from the surfaces also showed colonization of the medical devices and the ultrasound scanner used for the ultrasound-guided introduction of the central catheters. The results of the study showed some deviations concerning the recommendations; however, they are comparable to other studies conducted internationally, especially in terms of hand hygiene.

Conclusion: Our study results highlight some shortcomings adherence to hygiene measures like inconsistent disinfection of medical devices and dialysis stations, as well as insufficient hand hygiene practices among some staff members. However, we observed an improvement in practices following the implementation of awareness-raising sessions. To maintain improved hygiene practices and prevent infections, it is crucial to provide ongoing training for staff, ensure adequate resources, and regularly monitor compliance with hygiene standards.

Introduction: The study was performed to examine the effects of death anxiety on diet-fluid restriction non-adherence in hemodialysis patients.

Methods: This descriptive, cross-sectional, and correlational study was performed with 118 hemodialysis patients who received treatment in the dialysis unit of a university hospital and a state hospital in Elazığ, eastern Turkey. The study data were obtained with the "Descriptive Data Form", "Death Anxiety Scale", and "Dietary and Fluid Restriction Non-Adherence Scale".

Findings: The average Death Anxiety Scale total score of the patients was 10.00 ± 4.75. The "Duration of non-adherence with diet" mean score was 1.66 ± 1.70, "Degree of non-adherence with diet" mean score was 1.24 ± 1.19, "Duration of non-adherence with fluid restriction" mean score was 1.61 ± 1.71, and "Degree of non-adherence with fluid restriction" mean score was 1.16 ± 1.13. The independent variable Death Anxiety Scale significantly and negatively affected the dependent variable "Duration of non-adherence with diet", "Degree of non-adherence with diet", "Duration of non-adherence with fluid restriction", and "Degree of non-adherence with fluid restriction".

Discussion: Hemodialysis patients face serious death anxiety, their degree of non-adherence with diet-fluid restriction was low as death anxiety scores increased, and the degree of non-adherence with diet-fluid restriction decreased.

Introduction: Vitamin D deficiency is prevalent among patients undergoing hemodialysis. This study aimed to investigate the associations between vitamin D levels and clinical parameters with the risk of COVID-19 infection, severity, and mortality in hemodialysis patients with end-stage kidney disease (ESKD).

Methods: This retrospective cohort study included 198 hemodialysis patients from a single center. Vitamin D deficiency was defined by the last measurement of 25-hydroxycholecalciferol less than 20 ng/mL. Vitamin D deficiency and vitamin D supplements were combined to categorize patients into three groups: deficiency, uncertain deficiency, and likely sufficient. COVID-19 infection status, severity, and outcomes were recorded. Statistical analyses were performed to assess the associations between vitamin D levels and COVID-19 severity and mortality.

Findings: Among the 198 patients, 73 patients (37%) were in the deficiency group, 29 patients (15%) had uncertain deficiency, and 96 patients (48%) were likely sufficient. The overall COVID-19 infection rate was 59%. The deficiency group had a similar infection rate (60.3%) compared to those with likely sufficient levels (54.2%). However, the severity and mortality rates of vitamin D deficiency group had a significantly higher rate than those with likely sufficient levels. Multivariate logistic regression analysis showed that vitamin D deficiency and uncertain deficiency group were significantly associated with an increased risk of COVID-19 severity (OR = 22.57, p = 0.01 and OR = 15.8, p = 0.03, respectively). Uncertain deficiency group was significantly associated with an increased risk of COVID-19 mortality (OR = 12.93, p = 0.04), while the deficiency group should similarly trend but did not reach statistical significance.

Discussion: Vitamin D deficiency is associated with an increased risk of COVID-19 severity in hemodialysis patients with ESKD. These findings suggest that monitoring and managing vitamin D levels may be important in reducing the risk of COVID-19 severity in this vulnerable population.

Introduction: Phosphate binders are commonly used in patients receiving kidney replacement therapy (KRT), aiming to reduce and maintain serum phosphorus. Chronic kidney disease-mineral and bone disorder has been linked to reduced lifespan and worsened quality of life. This study aims to examine the efficacy and safety of sucroferric oxyhydroxide versus sevelamer carbonate in patients receiving KRT.

Methods: The data sources examined were MEDLINE (PubMed), Scopus, and the Cochrane Central Register of Controlled Clinical Trials with a search deadline of October 2023. We examined randomized controlled trials that compared sucroferric oxyhydroxide versus sevelamer carbonate in the adult population receiving KRT. We performed a meta-analysis combining the data from trials, using R-studio.

Findings: Inclusion criteria were met by five randomized trials. There was no statistically significant difference in the reduction of serum phosphorus between the two groups (MD: -0.07 mmol/L, 95% CI-random effects: -0.15 to 0.02). In the same line, a non-statistically significant difference was observed in serum i-PTH reduction between the two drugs (MD = -1.53 mg/dL, 95% CI = (-4.45, 1.4), p = 0.26, random effects model). No statistically significant difference was observed in all adverse events between the two groups (odds ratio: 1.11, 95% CI: 0.65-1.88, random effects model). Further analysis of gastrointestinal adverse events revealed that sevelamer carbonate increases gastrointestinal adverse events by up to 60% (odds ratio: 1.60, 95% CI: 1.31-1.97, common (fixed) effect model).

Discussion: This meta-analysis of randomized trials showed that both drugs, sucroferric oxyhydroxide and sevelamer equally and effectively controlled serum phosphorus levels, whereas sucroferric oxyhydroxide revealed a better profile in terms of gastrointestinal adverse events. Sucroferric oxyhydroxide is a valuable option for patients receiving KRT when sevelamer carbonate is more difficult to tolerate.

Introduction: The complexity of managing patients with end-stage kidney disease on hemodialysis underscores the importance of implementing quality improvement (QI) initiatives to enhance patient safety and prioritize patient-centered care. To address this, we established a QI committee at our tertiary academic center focusing on evidence-based practices, patient-centered approaches, and cost efficiency. To facilitate the seamless implementation of QI initiatives, we leveraged the capabilities of our electronic medical record (EMR) system.

Methods: This review details effective strategies for optimizing use of an EMR system to successfully implement QI efforts. Drawing from our experience, we provide detailed descriptions and practical insights that can be applied to other EMRs.

Findings: The creation of a secure and accessible dashboard, offering real-time data on quality metrics, stands out as the most notable feature. This dashboard operates through an algorithm that merges data from both our dialysis and hospital EMR systems. Its primary objectives are to streamline the identification of high-priority patients, enhance team communication, and facilitate tracking of quality indicators. Additionally, we integrated clinical pathways, checklists, and standardized protocols into the renal EMR to ensure smooth implementation of QI interventions. Notable examples of these interventions include an incremental hemodialysis protocol, a new hemodialysis start checklist, vaccination care plans, and personalized kidney transplant workups. Programmed electronic automatic reminders have proven invaluable in ensuring timely follow-ups of assigned tasks. The EMR has also contributed to medication optimization and deprescribing by generating patient lists based on specific medication classes. Finally, the EMR's capability to swiftly generate lists of patients with specific features has significantly facilitated targeted QI interventions.

Conclusions: Leveraging the capabilities of an EMR system can be crucial for enhancing care of hemodialysis patients and implementing effective QI initiatives.
