Iatrogenic arteriovenous fistula in the brachial artery after percutaneous coronary intervention in a patient with end stage kidney disease.

Iatrogenic arteriovenous fistula (AVF) is a complication accompanying venous and arterial puncture. Herein we report a case of ligation closure of an iatrogenic AVF in the brachial artery after percutaneous coronary intervention (PCI) for the patient with end-stage kidney disease (ESKD). A 68-year-old woman presented with a history of several coronary angiographies (CAG) and PCI through the right brachial artery.

The predictive markers of severity and mortality in hospitalized hemodialysis patients with COVID-19 during Omicron epidemic.

Introduction: Predictive markers and prognosis remain unclear in hospitalized hemodialysis (HD) patients with coronavirus disease 2019 (COVID-19) during the Omicron epidemic.

Methods: We evaluated characteristics, laboratory parameters, and outcomes in hospitalized HD patients with COVID-19 (n = 102) at two centers between January and April 2022.

Results: The 30-day mortality rate was higher in moderate-critical group (n = 43) than mild group (n = 59) (16.

The Impact of Tunneled Central Venous Hemodialysis Catheter on Mortality of Elderly Hemodialysis Patients Hospitalized in a Long-Term Care Hospital.

Introduction: The association between tunneled central venous hemodialysis catheters (TCVCs) and mortality in hospitalized elderly hemodialysis (HD) patients remains unclear.

Methods: This retrospective observational study was conducted in a long-term care hospital. We evaluated the association between TCVC and mortality in HD patients hospitalized between 2015 and 2020.

EBV+ tumors exploit tumor cell-intrinsic and -extrinsic mechanisms to produce regulatory T cell-recruiting chemokines CCL17 and CCL22.

The Epstein-Barr Virus (EBV) is involved in the etiology of multiple hematologic and epithelial human cancers. EBV+ tumors employ multiple immune escape mechanisms, including the recruitment of immunosuppressive regulatory T cells (Treg). Here, we show some EBV+ tumor cells express high levels of the chemokines CCL17 and CCL22 both in vitro and in vivo and that this expression mirrors the expression levels of expression of the EBV LMP1 gene in vitro.

Tumors establish resistance to immunotherapy by regulating T recruitment via CCR4.

Background: Checkpoint inhibitors (CPIs) such as anti-PD(L)-1 and anti-CTLA-4 antibodies have resulted in unprecedented rates of antitumor responses and extension of survival of patients with a variety of cancers. But some patients fail to respond or initially respond but later relapse as they develop resistance to immune therapy. One of the tumor-extrinsic mechanisms for resistance to immune therapy is the accumulation of regulatory T cells (T) in tumors.
