Revisiting ICD Therapy for Primary Prevention in Patients With Heart Failure and Reduced Ejection Fraction.

Implantable cardioverter-defibrillators (ICDs) are recommended to reduce the risk of sudden cardiac death (SCD) in patients with heart failure with reduced ejection fraction (HFrEF). The landmark studies leading to the current guideline recommendations preceded the 4 pillars of guideline-directed medical therapies (GDMTs). Therefore, some have questioned the role of ICDs for primary prevention in current clinical practice.

Prevalence of SPOP and IDH Gene Mutations in Prostate Cancer in a Jordanian Population.

Speckle-type POZ (SPOP) is described as an essential tumor suppressor factor in gastric cancer, colorectal cancer, and prostate cancer (PCa). SPOP gene mutations were reported in primary human PCa. Isocitrate dehydrogenase-1 (IDH1) oncogene mutations were detected in gliomas, acute myeloid leukemia, some benign and malignant cartilaginous tumors, and only 1% of PCa.

Long-Term Outcomes of Subcutaneous Versus Transvenous Implantable Cardioverter Defibrillator Use Among Patients on Maintenance Dialysis.

Background: Despite an elevated risk of sudden cardiac death among dialysis patients, implantable cardioverter defibrillators (ICDs) have not been shown to improve mortality and are associated with high complication rates. Subcutaneous (S-)ICDs may reduce the risk of complications for eligible dialysis patients, but safety and benefits vs transvenous (TV-ICDs are unknown.

Objective: To compare long-term outcomes between dialysis patients receiving S-ICD vs TV-ICDs.

State of the art of mobile health technologies use in clinical arrhythmia care.

The rapid growth in consumer-facing mobile and sensor technologies has created tremendous opportunities for patient-driven personalized health management. The diagnosis and management of cardiac arrhythmias are particularly well suited to benefit from these easily accessible consumer health technologies. In particular, smartphone-based and wrist-worn wearable electrocardiogram (ECG) and photoplethysmography (PPG) technology can facilitate relatively inexpensive, long-term rhythm monitoring.

Cardiac implantable electronic device patient follow-up: Assessment of U.S. practice.

Background: A 2015 expert consensus statement recommended that patients with cardiac implantable electronic devices receive remote monitoring and at least 1 in-office evaluation annually.

Objective: The purpose of this study was to examine whether patients who underwent implantation of a new cardiac implantable electronic device received care concordant with consensus statement recommendations.

Methods: We examined the rate of follow-up office visits and remote monitoring for 211,346 Medicare beneficiaries with an implantation of a new cardiac implantable electronic device between October 2015 and December 2020.

Analysis of IDH and EGFR as biomarkers in glioblastoma multiforme: A case-control study.

Background: Glioblastoma multiforme (GBM) is a very aggressive primary central nervous system (CNS) tumor with limited therapeutic options and poor prognosis. This study aimed to analyze the association between single nucleotide polymorphisms (SNPs), including IDH1 rs121913500C > T, IDH2 rs11540478G > A, and EGFR rs1468727C > T, and their association on the risk and overall survival of GBM patients in Jordan.

Methods: Using a case-control study design involving 63 GBM patients and 226 healthy controls was conducted at King Abdullah University Hospital in Jordan.

Expert Panel Perspective: Shared Decision-Making in Multidisciplinary Team-Based Cardiovascular Care.

Shared decision-making (SDM) and multidisciplinary team-based care delivery are recommended across several cardiology clinical practice guidelines. However, evidence for benefit and guidance on implementation are limited. Informed consent, the use of patient decision aids, or the documentation of these elements for governmental or societal agencies may be conflated as SDM.

RAndomized Cluster Evaluation of Cardiac ARrest Systems (RACE-CARS) trial: Study rationale and design.

Out-of-hospital cardiac arrest (OHCA) occurs in nearly 350,000 people each year in the United States (US). Despite advances in pre and in-hospital care, OHCA survival remains low and is highly variable across systems and regions. The critical barrier to improving cardiac arrest outcomes is not a lack of knowledge about effective interventions, but rather the widespread lack of systems of care to deliver interventions known to be successful.

Tonsillar synovial sarcoma, unusual anatomical location: case report and literature review.

Background: Synovial sarcoma is a rare soft tissue malignancy, occasionally found in the head and neck region. The diagnosis necessitates a multidisciplinary approach involving the clinical presentation, proper imaging studies and histological confirmation, with molecular testing for definitive identification. Treatment entails surgical resection with adjuvant therapies as needed.

Exploring Genetic Determinants: A Comprehensive Analysis of Serpin B Family SNPs and Prognosis in Glioblastoma Multiforme Patients.

Serpins are serine proteinase inhibitors, with several serpins being overexpressed in cancer cells. Thus, we aim to analyze the single-nucleotide polymorphism (SNP) of and its association with GBM survival. A cohort of 63 GBM patients recruited from King Abdullah University Hospital in Jordan underwent polymorphism analysis and overall survival (OS) assessments.

Relationship between sex, body size, and cardiac resynchronization therapy benefit: A patient-level meta-analysis of randomized controlled trials.

Background: Women might benefit more than men from cardiac resynchronization therapy (CRT) and do so at shorter QRS durations.

Objective: This meta-analysis was performed to determine whether sex-based differences in CRT effects are better accounted for by height, body surface area (BSA), or left ventricular end-diastolic dimension (LVEDD).

Methods: We analyzed patient-level data from CRT trials (MIRACLE, MIRACLE ICD, MIRACLE ICD II, REVERSE, RAFT, COMPANION, and MADIT-CRT) using bayesian hierarchical Weibull regression models.

Point-of-Care Chemistry-Guided Dialysate Adjustment to Reduce Arrhythmias: A Pilot Trial.

Introduction: Excessive dialytic potassium (K) and acid removal are risk factors for arrhythmias; however, treatment-to-treatment dialysate modification is rarely performed. We conducted a multicenter, pilot randomized study to test the safety, feasibility, and efficacy of 4 point-of-care (POC) chemistry-guided protocols to adjust dialysate K and bicarbonate (HCO3) in outpatient hemodialysis (HD) clinics.

Methods: Participants received implantable cardiac loop monitors and crossed over to four 4-week periods with adjustment of dialysate K or HCO3 at each treatment according to pre-HD POC values: (i) K-removal minimization, (ii) K-removal maximization, (iii) Acidosis avoidance, and (iv) Alkalosis avoidance.
