Voltage Gated Calcium Channel Dysregulation May Contribute to Neurological Symptoms in Calmodulinopathies.

Calmodulinopathies are caused by mutations in calmodulin (CaM), and result in debilitating cardiac arrythmias such as long-QT syndrome (LQTS) and catecholaminergic polymorphic ventricular tachycardia (CPVT). In addition, many patients exhibit neurological comorbidities, including developmental delay and autism spectrum disorder. Until now, most work into these mutations has focused on cardiac effects, identifying impairment of Ca /CaM-dependent inactivation (CDI) of Ca 1.

Stent-in-Stent Intervention for Pulmonary Vein in Stent Restenosis: A Long-Term Follow-Up Case Report.

Introduction: Pulmonary vein (PV) restenosis develops with reported incidence rates of up to 50%. Balloon angioplasty seems to be the widely preferred treatment of choice.

Method And Results: A 54-year-old man with long history of atrial fibrillations developed PVS secondary to multiple radiofrequency ablation procedures.

Effect of Dapagliflozin on Measured vs. Panel-Estimated Glomerular Filtration Rate.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors can cause a reversible decline in glomerular filtration rate (GFR), which may influence dosing recommendations for renally excreted medications. In practice, GFR is typically estimated by serum creatinine concentration, but creatinine may not be a reliable indicator of GFR decline in the setting of SGLT2 inhibitor use. Alternative filtration markers such as cystatin C, β-trace protein (BTP), and β2-microglobulin (B2M) may be more appropriate, but little is known about how these markers are affected by SGLT2 inhibitor use.

Improve time to anti-coagulation reversal for hemorrhagic strokes.

Background: Oral anticoagulation (OAC) is a risk factor for intracerebral hemorrhage (ICH) which is an important source of disability and mortality. OAC-associated ICH (OAC-ICH) patients have worse outcomes as compared to ICH patients not on OAC, likely because of the associated larger stroke volumes, higher propensity to intraventricular hemorrhage, and a higher risk of rebleeding. Although current guidelines recommend that OAC should be reversed quickly, many health care systems have not developed a process for optimizing that aspect of care.
