Over 200 point mutations in the ryanodine receptor (RyR2) of the cardiac sarcoplasmic reticulum (SR) are known to be associated with cardiac arrhythmia. We have already reported on the calcium signaling phenotype of a point mutation in RyR2 Ca binding site Q3925E expressed in human stem-cell-derived cardiomyocytes (hiPSC-CMs) that was found to be lethal in a 9-year-old girl. CRISPR/Cas9-gene-edited mutant cardiomyocytes carrying the RyR2-Q3925E mutation exhibited a loss of calcium-induced calcium release (CICR) and caffeine-triggered calcium release but continued to beat arrhythmically without generating significant SR Ca release, consistent with a remodeling of the calcium signaling pathway.

Research on the links between intimate relationships and PTSD and the treatments for PTSD tend to be limited to couples in which only one partner within the dyad has PTSD. No investigations, to our knowledge, have empirically examined the simultaneous provision of evidence-based PTSD treatment to both partners in an intimate relationship diagnosed with PTSD. The current case study describes two partners in a different-sex relationship, both diagnosed with current PTSD, who received individual Prolonged Exposure (PE) therapy at the same time as part of a larger randomized clinical trial.

Patients with obesity-related heart failure with preserved ejection fraction (HFpEF) display circulatory volume expansion and pressure overload contributing to cardiovascular-kidney end-organ damage. In the SUMMIT trial, patients with HFpEF and obesity were randomized to the long-acting glucose-dependent insulinotropic polypeptide receptor and glucagon-like peptide-1 receptor agonist tirzepatide (n = 364, 200 women) or placebo (n = 367, 193 women). As reported separately, tirzepatide decreased cardiovascular death or worsening heart failure.

Objective: Systemic lupus erythematosus (SLE) affects nine women to every man worldwide, and these patients are at greater risk for cardiovascular disease (CVD) morbidity and mortality. Clinical studies have demonstrated that patients with SLE are more likely to develop CVD, including cardiac and vascular dysfunction. Although many preclinical models of SLE are available, including treatment with Toll-like receptor (TLR) 7/8 agonists, a consistent preclinical model of SLE-like CVD with systemic, cardiac, renal, and cerebral endothelial activation and cardiac dysfunction has yet to be described.

Article Synopsis
  • * In the first trial (RCT-I), there were no significant differences in important health outcomes like cardiovascular mortality or stroke, while the second trial (RCT-II) showed a benefit in responder patients using shunts over a sham treatment.
  • * The atrial shunt treatment in responders led to fewer heart failure events and better health-related quality of life measured by KCCQ, but also had a higher rate of ischemic stroke and reduced worsening kidney dysfunction compared to sham treatment.

Article Synopsis
  • The study aimed to investigate the impact of beta-blocker (BB) use on clinical outcomes in patients with heart failure, specifically those with mildly reduced and preserved ejection fraction, using a large observational analysis.
  • A total of 16,951 patients were analyzed, with 75.6% receiving BB treatment; results showed that while unadjusted outcomes were similar for BB users and non-users, adjusted outcomes indicated that BB users had better outcomes, especially in those with atrial fibrillation.
  • The conclusions suggest that BB treatment does not correlate with worse heart failure outcomes, even after considering various other health factors.

Article Synopsis
  • The study evaluated the impact of Optimal Medical Therapy (OMT) scoring on long-term clinical outcomes for patients with chronic heart failure and reduced ejection fraction (HFrEF) by classifying patients based on their use and dosing of guideline-directed medical therapy (GDMT).
  • Using data from the CHAMP-HF study involving 4,582 participants, researchers found that half of the patients had optimal treatment while a significant portion had suboptimal care.
  • Results indicated that patients receiving optimal therapy had significantly lower rates of all-cause and cardiovascular death compared to those with suboptimal therapy, suggesting OMT scores are useful for assessing patient risk in HFrEF.

Purpose: The best possible outcomes in infantile epileptic spasms syndrome require electroclinical remission; however, determining electrographic remission is not straightforward. Although the determination of hypsarrhythmia has inadequate interrater reliability (IRR), the Burden of AmplitudeS and Epileptiform Discharges (BASED) score has shown promise for the reliable interictal assessment of infantile epileptic spasms syndrome. Our aim was to develop a BASED training program and assess the IRR among learners.

All definitions of treatment-resistant depression (TRD) require that patients have experienced insufficient benefit from one or more adequate antidepressant trials. Thus, identifying "failed, adequate trials" is key to the assessment of TRD. The Antidepressant Treatment History Form (ATHF) was one of the first and most widely used instruments that provided objective criteria in making these assessments.

Article Synopsis
  • Researchers studied serum levels of 4123 proteins in 1117 patients with heart failure with preserved ejection fraction (HFpEF) to identify prognostic markers linked to clinical outcomes.
  • A total of 288 proteins were found to be significantly associated with heart failure hospitalization and cardiovascular death, with specific proteins like B2M and TIMP1 showing strong correlations.
  • The study concluded that the protein markers for HFpEF are similar to those for heart failure with reduced ejection fraction, implying that the derived proteomic risk scores do not offer improved predictive power for HFpEF patients.

Esophageal thermal injury is one of the most devastating complications of atrial radiofrequency ablation, and its diagnosis can be challenging. In this report, we highlight the novel use of free water as a contrast material to better visualize the esophageal lumen in a patient with anaphylaxis to Iodinated contrast media and Gadolinium who recently underwent atrial fibrillation ablation. This becomes particularly handy in patients with contrast allergy, and further emphasizes the role of multimodality imaging.
