Local atrial bipolar electrogram voltage drops during cardiac magnetic resonance guided catheter ablation of typical atrial flutter: Associations with delivered radiofrequency energy and peri-procedural imaging.

Background: Cardiac magnetic resonance (CMR)-guided catheter ablation of the cavotricuspid isthmus (CTI) has been proven feasible, but determinants of local electrogram (EGM) voltage drops during radiofrequency (RF) applications are unknown.

Objective: The purpose of this study was to investigate local atrial bipolar EGM voltage drops and the association with delivered RF energy and anatomical information derived from peri-procedural CMR imaging.

Methods: In consecutive patients undergoing CMR-guided CTI ablation procedures, relative EGM voltage drops for RF applications ≥20 seconds were calculated.

Inhibitor development upon switching from plasma-derived to recombinant factor VIII in previously untreated patients with severe hemophilia A: the PUP-SWITCH study.

Background: The SIPPET randomized clinical trial showed that in previously untreated patients (PUPs) with severe hemophilia A, treatment with plasma-derived factor (F)VIII (pdFVIII) within the first 50 exposure days (EDs) was associated with a lower cumulative incidence of inhibitors than with recombinant FVIII (rFVIII). Switching to rFVIII beyond 50 EDs with pdFVIII is a treatment often implemented by many centers. The question is whether or not this switch may induce a risk of inhibitor development.

Recanalization Does Not Always Equate to Reperfusion: No-Reflow Phenomenon After Successful Thrombectomy.

Background: Thrombectomy for acute large vessel occlusion is a well-established treatment for stroke prevention. However, futile recanalization cases, where no-reflow occurs despite successful recanalization, have been reported. This study aimed to assess cerebral hemodynamics immediately after thrombectomy and their relationship with clinical outcomes.

Hormone-related thrombosis: duration of anticoagulation, risk of recurrence, and the role of hypercoagulability testing.

Hormone-related venous thromboembolism (VTE) is common and entails scenarios in which VTE occurs during exposure to exogenous or endogenous female sex hormones, typically estrogen and progestogen. For the management of hormone-related VTE, it is important to realize that many patients use these hormones for a vital purpose often strongly related to the patient's well-being and quality of life. In this review we discuss clinical cases of VTE related to hormonal contraceptive use and pregnancy to illustrate key considerations for clinical practice.

Disease-modifying treatment and disability progression in subclasses of patients with primary progressive MS: results from the Big MS Data Network.

Background: Effectiveness of disease-modifying treatment (DMT) in people affected by primary progressive multiple sclerosis (PPMS) is limited. Whether specific subgroups may benefit more from DMT in a real-world setting remains unclear. Our aim was to investigate the potential effect of DMT on disability worsening among patients with PPMS stratified by different disability trajectories.

Hospital-Acquired Pressure Ulcers and Long-Term Motor Score Recovery in Patients With Acute Cervical Spinal Cord Injury.

Importance: Pressure ulcers (PUs) are (1) prevalent secondary complications after spinal cord injury (SCI), (2) present with elevated systemic inflammatory tone, and (3) may interfere with healing processes underlying neurological recovery (disrepair).

Objective: To investigate whether PUs acquired during initial hospitalization are associated with neurological and functional long-term outcome and survival after SCI.

Design, Setting, And Participants: Multicenter cohort study at 20 centers of the prospective SCI Model Systems (SCIMS) Database (Birmingham, AL).

External validation of the Leiden Thrombosis Recurrence Risk Prediction models (L-TRRiP) for the prediction of recurrence after a first venous thrombosis in the Heart and Vascular Health study.

Background: Long-term outcome after a first venous thromboembolism (VTE) might be optimized by tailoring anticoagulant treatment duration on individual risks of recurrence and major bleeding. The L-TRRiP models (A-D) were previously developed in data from the Dutch Multiple Environment and Genetic Assessment of Risk Factors for Venous thrombosis study to predict VTE recurrence.

Objectives: We aimed to externally validate models C and D using data from the United States Heart and Vascular Health (HVH) study.

Surgical specialists face higher a risk for malpractice compared to their non-surgical colleagues.

In previous studies, surgical specialties accounted for most malpractice claims. The objective of the present study was to determine the risk for malpractice claims for physicians working in hospitals. A retrospective observational study using anonymized closed malpractice claims between 2007 up to 2021 from two Dutch insurers was carried out.

The Prevalence of Diffuse Large B-Cell Lymphoma Varies Substantially by Methods Applied: Results From a Population-Based Study.

Objectives: Accurate prevalence estimates of diffuse large B-cell lymphoma (DLBCL) are important for numerous purposes including orphan drug designation. A key criterion for orphan drug designation is a disease prevalence of less than 5/10,000 persons. The objective is to apply and compare different methods of prevalence assessment.

Time trends in antithrombotic therapy during pregnancy and maternal and perinatal outcomes in the Netherlands (2013-19): a nationwide cohort study.

Background: Considering the paucity of data, we aimed to describe nationwide time trends in antithrombotic therapy during pregnancy and risks of maternal and perinatal outcomes in the Netherlands.

Methods: In this nationwide cohort study, all female individuals aged 16-45 years with delivery records in the Dutch perinatal registry between Jan 1, 2013, and Dec 31, 2019, and their infants, were included. Individually linked data from Statistics Netherlands on outpatient medication prescriptions, in-hospital diagnoses, and mortality were used to evaluate time trends in antithrombotic therapy during pregnancy, and risks of maternal and perinatal outcomes (including thromboembolism, bleeding, preeclampsia and eclampsia, and low birthweight).

Moving Beyond Medical Statistics: A Systematic Review on Missing Data Handling in Electronic Health Records.

Missing data in electronic health records (EHRs) presents significant challenges in medical studies. Many methods have been proposed, but uncertainty exists regarding the current state of missing data addressing methods applied for EHR and which strategy performs better within specific contexts. All studies referencing EHR and missing data methods published from their inception until 2024 March 30 were searched via the MEDLINE, EMBASE, and Digital Bibliography and Library Project databases.
