Antithrombotic therapy and the risk of pocket hematoma after subcutaneous implantable cardioverter-defibrillator implantation.

Background: Little data exists regarding the optimal antithrombotic strategy during S-ICD implantation to prevent pocket hematomas. This study explores the association between perioperative antithrombotic management and the occurrence of pocket hematoma following S-ICD implantation.

Methods: All patients who underwent de novo S-ICD implantation between February 2009 and January 2023 at Amsterdam UMC were included.

The Added Diagnostic Value of Transcatheter CT Hepatic Arteriography for Intraprocedural Detection of Previously Unknown Colorectal Liver Metastases During Percutaneous Ablation and Impact on the Definitive Treatment Plan.

Purpose: This study assessed the diagnostic value of CT hepatic arteriography (CTHA) for the intraprocedural detection of previously unknown colorectal liver metastases (CRLM) and the impact on the definitive treatment plan.

Materials And Methods: All patients treated with CTHA-guided percutaneous ablation for CRLM between January 2012 and March 2022 were identified from the Amsterdam Colorectal Liver Met Registry (AmCORE). Radiology reports of the ablative procedure and follow-up imaging were reviewed to see if (a) previously unknown CRLM were detected intra-procedurally and if (b) new CRLM, potentially missed on CTHA, appeared within 6 months following the procedure; three abdominal radiologists re-reviewed the baseline CTHA scans of these patients with early recurrence.

Genetic survey of a group of children with clefting: implications for genetic counseling.

A cleft lip, cleft palate, or both are associated with a high frequency of other anomalies. This study gives an inventory of associated anomalies in a consecutive group of children (n = 36) with clefts, referred to a local multidisciplinary cleft team in the Netherlands. In 47.

Monoclonal antibody mediated targeting of enzymes. A comparative study using the mouse spleen as a model system.

The aim of this study was to target enzymes specifically to cells in the murine spleen. Monomeric and polymeric conjugates of the enzymes horseradish peroxidase or alkaline phosphatase and monoclonal antibodies against cell surface determinants were prepared. Highly specific in vivo targeting of enzymes to macrophages was obtained only when monomeric MAb-enzyme conjugates were used.

Development of antibody-forming cells in follicles of lymph nodes of mice after continuous antigenic stimulation.

It was the purpose of the present study to test a hypothesis on the direct differentiation of newly formed memory B cells into antibody-forming cells (AFC) in the follicles of lymph nodes. AFC may develop in follicles when mobile antigen is present at the moment that such memory B cells have completed their differentiation under influence of immune complexes trapped on follicular dendritic cells (FDC). In order to study whether the simultaneous presence of mobile antigen and immobilized immune complexes on FDC alters the normal distribution of AFC in lymph nodes, different immunization protocols with the thymus-dependent antigens trinitrophenylated keyhole limpet haemocyanin (TNP-KLH) and horseradish peroxidase (HRP) were used.
