Background: Spontaneous primary intracerebral hemorrhage (ICH) accounts for 10%-15% of strokes and is accompanied by ventricular involvement in 10%-30% of cases. Intraventricular hemorrhage (IVH) is a poor prognostic factor and the current treatment paradigm of external ventricular drainage requires frequent flushing and replacement. Given the documented high rate of failure standard EVD catheters, we sought to determine if the use of the IRRAflow system with the addition of alteplase would be beneficial in this patient population for the treatment of IVH associated with primary hypertensive ganglionic hemorrhages.
Methods: Three patients with ganglionic hemorrhages and IVH underwent treatment with the IRRAflow system at our institution from December 2022 to January 2023. A retrospective review was then performed of patients with primary hypertensive ganglionic hemorrhages and EVD placement at our institution from January 2021 to present day.
Results: Three patients underwent treatment with the IRRAflow system and continuous lavage of Tissue Plasminogen Activator (tPA). The IVH was efficiently cleared in all cases and the drains were removed within 8 days in all cases. No patients required replacement of the drain and there were no hemorrhagic complications noted. In our retrospective review, 28 patients were identified who underwent placement of a standard EVD for the treatment of primary hypertensive ganglionic hemorrhages. When patients who had early withdrawal of care were excluded, the average length of EVD treatment was 11.3 days and the EVD replacement rate was 24%.
Conclusions: We demonstrate here that the use of the IRRAflow system for the treatment of primary hypertensive hemorrhages with IVH results in rapid clearance of the IVH without safety concerns. Compared to historical controls there was a decrease in EVD duration, EVD replacement and, ICU LOS.

Association between estrogen and kidney function: population based evidence and mutual bidirectional Mendelian randomization study.

Department of Nephrology, Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine, Shanghai, China.
Background: Previous studies have suggested a potential role of estrogen in the pathophysiology of chronic kidney disease (CKD); however, the association and causality between estrogen and kidney function remain unclear.
Methods: The cross-sectional correlation between serum estradiol concentration and estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratio (ACR) was analyzed using data from the National Health and Nutrition Examination Survey 2013-2016. Causality was tested using mutual bidirectional Mendelian randomization (MR) approaches based on six large-scale GWAS studies.
Novel Therapies for Right Ventricular Failure.
Curr Cardiol Rep

Pediatric Advanced Heart Failure and Heart Transplant Program, University of Mississippi Medical Center, 2500 N State Street, Jackson, MS, USA.
Purpose Of Review: Traditionally viewed as a passive player in circulation, the right ventricle (RV) has become a pivotal force in hemodynamics. RV failure (RVF) is a recognized complication of primary cardiac and pulmonary vascular disorders and is associated with a poor prognosis. Unlike treatments for left ventricular failure (LVF), strategies such as adrenoceptor signaling inhibition and renin-angiotensin system modulation have shown limited success in RVF.
