Life-saving vascular access in vascular capital exhaustion: single center experience in intra-atrial catheters for hemodialysis.
CONCLUSION: Placing an IAC to perform HD is associated to significant risks and high mortality. However, when alternative RRT are exhausted, or as a bridge to others modalities, this option should be considered. PMID: 28355409 [PubMed - in process]

Vascular access cannulation in hemodialysis patients: technical approach.
CONCLUSIONS: The vascular access cannulation technique depends on the vascular access characteristics and expertise of cannulators. Clinical trials are required for the formulation of guidelines for vascular access cannulation. PMID: 31826075 [PubMed - as supplied by publisher]

Relevance of a skilled vascular surgeon and optimized facility practices in the long-term patency of arteriovenous fistulas: a prospective study.
CONCLUSIONS: Results suggest that a long-lasting, suitable AVF is feasible in almost all patients. The surgeon's skills and facility practices can have an important role in the long term outcome of AVF. PMID: 31063174 [PubMed - as supplied by publisher]

Erythropoietin resistance in end-stage renal disease patient with gastric antral vascular ectasia.
Authors: Lee DJ, Fragata J, Pestana JO, Draibe S, Canziani ME, Cendoroglo M, Góes MÂ Abstract We observed a case of recombinant human erythropoietin resistance caused by Gastric Antral Vascular Ectasia in a 40-year-old female with ESRD on hemodialysis. Some associated factors such as autoimmune disease, hemolysis, heart and liver disease were discarded on physical examination and complementary tests. The diagnosis is based on the clinical history and endoscopic appearance of watermelon stomach. The histologic findings are fibromuscular proliferation and capillary ectasia with microvascular thrombosis of the lamin...

Translumbar hemodialysis long-term catheters: an alternative for vascular access failure.
CONCLUSION: TLDC is an option for patients with VA failure, improving survival and acting as a bridge for renal transplantation. PMID: 30281060 [PubMed - as supplied by publisher]

Cbfa1 expression in vascular smooth muscle cells may be elevated by increased nitric oxide/iNOS.
CONCLUSION: This study showed that increased NO/iNOS expression causes an increase in cbfa1 expression in VSMC. PMID: 32459278 [PubMed - as supplied by publisher]

Hemodialysis Vascular access maintenance in the Covid-19 pandemic: Positioning paper from the Interventional Nephrology Committee of the Brazilian Society of Nephrology.
Authors: Franco RP, Costa CBS, Sousa CS, Rodrigues AT, Neves PDMM, Chula DC Abstract 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 procedure...

AGEs accumulation is related to muscle degeneration and vascular calcification in peritoneal dialysis patients
CONCLUSIONS: The study revealed associations between AGEs accumulation and lower muscle stiffness/density. Associations that linked muscle degeneration parameters with vascular calcification were observed.PMID:33650629 | DOI:10.1590/2175-8239-JBN-2020-0119

p-cresol but not p-cresyl sulfate stimulate MCP-1 production via NF- κB p65 in human vascular smooth muscle cells.
CONCLUSIONS: VSMC are involved in atherosclerosis lesion formation and production of MCP-1, which contributes to the inflammatory response initiation. Our results suggest that PC mediates MCP-1 production in VSMC, probably through NF-κB p65 pathway, although we hypothesize that PCS acts through a different subunit pathway since NF-κB p65 inhibitor was not able to inhibit MCP-1 production.

Vascular stiffness and healthy arterial aging in older patients with optimal blood pressure
CONCLUSION: Older people with optimal arterial blood pressure do not necessarily have HVA and could have c-fPWV values close to the limits established for CAS diagnosis.PMID:36638247 | DOI:10.1590/2175-8239-JBN-2022-0123en
