Impact of lactate levels on admission in STEMI patients with cardiogenic shock treated with IMPELLA.

The concomitant use of IMPELLA and veno-arterial extracorporeal membrane oxygenation (V-A ECMO) (ECPELLA) has been increasingly used to treat severe cardiogenic shock. However, the relationship between severity of heart failure on admission and prognosis based on differences in the mechanical circulatory support (MCS) is not fully understood. This study evaluated the association between lactate levels on admission and clinical outcomes based on differences in MCS.

Physcomitrium LATERAL SUPPRESSOR genes promote formative cell divisions to produce germ cell lineages in both male and female gametangia.

The evolution of green plants from aquatic to terrestrial environments is thought to have been facilitated by the acquisition of gametangia, specialized multicellular organs housing gametes. Antheridia and archegonia, responsible for producing and protecting sperm and egg cells, undergo formative cell divisions to produce a cell to differentiate into germ cell lineages and the other cell to give rise to surrounding structures. However, the genes governing this process remain unidentified.

Efficacy and Safety of Sodium Zirconium Cyclosilicate in the Management of Hyperkalemia in Patients with Heart Failure with Reduced and Mildly Reduced Ejection Fraction and Chronic Kidney Disease Treated with Spironolactone: Rationale for and Design of the REGISTA-K Trial.

Background: To evaluate whether sodium zirconium cyclosilicate (SZC) enables the up-titration of spironolactone without increasing the risk of hyper- and hypokalemia in patients with heart failure with reduced and mildly reduced ejection fraction (HFrEF and HFmrEF) and moderate/severe chronic kidney disease (CKD) who developed hyperkalemia during treatment with suboptimal spironolactone dose.

Methods: The REGISTA-K is a randomized, double-blind, placebo-controlled, multicenter trial that examined the efficacy and safety of SZC in up-titrating spironolactone without the occurrence of hyperkalemia or hypokalemia. A total of 266 patients with HFrEF and HFmrEF and hyperkalemia will be randomized in a 1:1 ratio to receive either SZC or placebo after treating hyperkalemia with SZC at 25 sites in Japan.

Hyperdifferentiated murine melanoma cells promote adaptive anti-tumor immunity but activate the immune checkpoint system.

Accumulating evidence suggests that phenotype switching of cancer cells is essential for therapeutic resistance. However, the immunological characteristics of drug-induced phenotype-switching melanoma cells (PSMCs) are unknown. We investigated PSMC elimination by host immunity using hyperdifferentiated melanoma model cells derived from murine B16F10 melanoma cells.
