BACKGROUND: Although the risk factors for positive follow-up blood cultures (FUBCs) in gram-negative bacteremia (GNB) have not been investigated extensively, FUBC has been routinely carried out in many acute care hospitals. We attempted to identify the risk factors and develop a predictive scoring model for positive FUBC in GNB cases. METHODS: All adults with GNB in a tertiary care hospital were retrospectively identified during a 2-year period, and GNB cases were assigned to eradicable and non-eradicable groups based on whether removal of the source of infection was possible...

INTRODUCTION: The development of thoracic central venous obstruction (TCVO) leads to narrowing of the vessel lumen which impacts blood flow and the placement of central venous access. The most common cause of TCVO is central venous catheters (CVCs) which can induce intravascular scarring or endoluminal obstruction via thrombus formation. AREAS COVERED: The Surfacer® System is used to obtain central venous access (CVA) in patients with TCVO by facilitating catheter insertion via the novel Inside-Out® approach...

The use of tunneled dialysis catheters (TDCs) for patients in need of hemodialysis treatments (HDs) cause a significant number of blood stream infections (BSIs), with very few viable preventative/treatment methods. Use of antibiotics are relatively ineffective due to the development of multi-drug resistant bacterial strains and their inability to penetrate bacterial biofilms. Nitric oxide (NO) is an endogenous gas molecule that has broad spectrum antimicrobial/anti-biofilm activity. In this study, the potential of creating a NO releasing insert device that is attached onto the hub region cap of TDCs and locally releases NO within the TDC hub is evaluated for its antimicrobial/anti-biofilm effectiveness...

The objective is to compare Multi-detector CT angiography (MDCTA) and digital subtraction angiography (DSA) in diagnosing hemodialysis catheter related-central venous stenosis (CVS). During a period of 6 years, hemodialysis patients with suspected catheter related-CVS who received both MDCTA and DSA were retrospectively enrolled. We analyzed the sensitivity, specificity, accuracy, Cohen's kappa coefficient (κ) and other diagnostic parameters for MDCTA compared to DSA. A total of 1533 vascular segments in 219 patients were analyzed...

The use of tunneled cuffed catheters (TCCs) for permanent blood access is increasing as the hemodialysis population ages. However, the higher mortality and complication rates associated with their use have been significant concerns. This single-center observational cohort study aimed to investigate clinical factors affecting mortality and complications in Japanese hemodialysis patients with a TCC.We enrolled 64 consecutive patients receiving hemodialysis through a TCC between 2012 and 2019. The primary outcome was all-cause mortality and the secondary outcome was the incidence of catheter-related complications at 2 years...

Fungal peritonitis in patients undergoing peritoneal dialysis (PD) is very difficult to treat and is associated with significant morbidity and mortality. Among fungal pathogens, Aspergillus peritonitis presents a higher mortality rate when compared to Candida peritonitis and its identification as well as appropriate treatment remains a challenge for the physicians. We critical reviewed all published cases in literature of Aspergillus peritonitis in PD patients. The results showed that a total of 55 cases (51% males) of Aspergillus peritonitis in PD patients were reported from 1968 to 2019...

The incidence and prevalence of renal replacement therapy has continued to increase in the pediatric population. Recent data have shown that hemodialysis was the most frequently used dialysis modality, especially in pediatric ESRD patients (age 0-21 years). A well-functioning vascular access is required for effective hemodialysis and choosing the best vascular access option for pediatric patients can be difficult. Pediatric vascular options include arteriovenous fistula, arteriovenous graft, and central venous catheters (CVCs)...

The cost and health burden of ESRD continues to increase globally. Total Medicare expenditure on dialysis has increased from 229 million USD in 1973 to 35.4 billion USD in 2016. Dialysis access can represent almost a tenth of these costs. Central venous catheters have been recognized as a significant factor driving costs and mortality in this population. Home dialysis, which includes peritoneal dialysis and home hemodialysis, is an effective way of reducing costs related to renal replacement therapy, reducing central venous catheter usage and in many cases improving the clinical and psychosocial aspects of patients' health...

Tunneled dialysis catheters remain the most common vascular access used to initiate hemodialysis. Unfortunately, their use is associated with higher morbidity and mortality when compared with arteriovenous fistulae or grafts. Different types of catheters with different designs and material properties function differently. Additional devices and medications can be used to decrease the rates of infection and thrombosis. The current available tunneled dialysis catheters remain far from the desired goal and innovation in the field of dialysis vascular access remains in dire need...

Chronic kidney disease (CKD) is a major noncommunicable disorder and has become the 9th leading cause of death in the United States. Most patients with CKD in the United States choose hemodialysis as their treatment of choice. A functioning arteriovenous access is essential to reduce dependence on central venous catheters. An arteriovenous fistula (AVF), though the preferred access, has a major limitation with a high primary maturation failure rate. A functioning AVF requires well-preserved vessels, both arteries and veins, along with an acceptable cardiac pump function...

OBJECTIVE: Renal dysfunction, requiring renal replacement therapy (RRT) is commonly encountered in patients with left ventricular assist devices (LVAD). Continuous flow LVAD (CFLVAD) is the most widely used device. Non-pulsatile blood flow begets special hemodynamic changes. This poses a unique challenge in choosing a long-term dialysis access for patients with CFLVAD where life expectancy is limited. METHODS: Sixty-one year old man with an implanted CFLVAD and renal dysfunction receiving intermittent RRT through a non-tunneled dialysis catheter had progressed to dialysis dependent renal failure...

Vascular accesses for hemodialysis are considered the patient's lifeline and their maintenance is essential for treatment continuity. Following the example of institutions in other countries affected by the Covid-19 pandemic, the Brazilian Society of Nephrology developed these guidelines for healthcare services, elaborating on the importance of carrying out procedures for the preparation and preservation of vascular accesses. Creating definitive accesses for hemodialysis, grafts and arteriovenous fistulas are non-elective procedures, as well as the transition from the use of non-tunneled catheters to tunneled catheters, which cause less morbidity...

INTRODUCTION: The implantation of acute or chronic vascular accesses for hemodialysis (HD) in end-stage kidney disease patients is a critical skill procedure for nephrologists, with an impact on short- and long-term outcomes of the modality and patient survival. Placement circumstances, however, may depend on the availability of technological support and will likely vary across the world. MATERIALS AND METHODS: We retrospectively reviewed our local experience with ultrasound-guided tunneled dialysis catheter (TDC) insertions but without access to fluoroscopic guidance...

Aneurysmal transformation of arteriovenous fistula (AVF) is a common complication and associated with increased risk of arrosive bleeding. Ligation of fistulous vein is conventional surgery for bleeding. This is followed by AVF malfunction and need for implantation of central venous catheter. We report reconstructive surgery and maintaining the function of AVF in a patient with aneurysmal transformation of AVF after arrosive bleeding. Reconstructive vascular surgery can significantly extend the period of patent AVF for hemodialysis...

Insertion of a central venous catheter is one of the most common invasive procedures applied in hemodialysis therapy for end-stage renal disease. The most important complication of a central venous catheter is catheter-related infections that increase hospitalization and duration of intensive care unit stay, cost of treatment, mortality, and morbidity rates. Pathogenic microorganisms, such as, bacteria and fungi, enter the body from the catheter insertion site and the surface of the catheter can become colonized...

BACKGROUND AND OBJECTIVES: For patients who rely on a tunneled cuffed catheter, the internal jugular vein is the preferred site of insertion. A few studies have suggested that the posterior approach for central lines is equivalent or better in comparison to the conventional central approach. However, there have been fewer studies examining tunneled cuffed catheter insertion using the posterior approach. We have performed many posterior insertions of tunneled cuffed catheters in our practice, and because the technique has not yet been comprehensively studied for long-term use, we performed a retrospective study to evaluate the safety and efficacy of posterior approach for tunneled cuffed catheter in maintained hemodialysis patients...
