Die Highlights vom Kongress des American College of Cardiology 2024

Im April diskutierten die Herz-Kreislauf-Spezialisten aus der ganzen Welt auf dem  Kongress des American College of Cardiology (ACC) u.a. neue Therapieansätze bei akutem Myokardinfarkt, koronarer Herzerkrankung, kardiogenem Schock oder Aortenklappenstenose. In unserem Kongress-Dossier haben wir für Sie Berichte über die „Late-Breaking Trials“ und andere wichtige Studien zusammengestellt.

Abstract

Purpose of Review

This article summarizes the emerging landscape of pediatric epilepsy, highlighting genetic contributions, and reviews approaches to genetic evaluation for pediatric epilepsy in this context.

Recent Findings

Advances in understanding the genetic basis for epilepsy over the last several years have been due in large part to the identification of de novo genetic variation underlying sporadic severe epilepsy in children; the genetic underpinnings of the more common epilepsies remain largely unknown. Next-generation sequencing approaches have been added to the repertoire of clinical tests for the evaluation of pediatric epilepsy, improving our ability to make positive diagnoses. Yields of over 50% are now being reported in selected groups of patients.

Summary

Genetic variation contributing to the risk for pediatric epilepsy spans continua of scale and influence. The highest yield of genetic testing is currently in children with sporadic severe epilepsy caused by de novo variation. The approach to genetic evaluation and interpretation of results requires an understanding of (1) the epilepsy phenotype and (2) the particular advantages and limitations of the different genetic tests available. Our understanding of genetic variation will continue to improve over time and “negative” results are best conceptualized as “unresolved” or “negative for now.”

Hirnblutung unter DOAK und VKA ähnlich bedrohlich

17.05.2024 Direkte orale Antikoagulanzien Nachrichten

Kommt es zu einer nichttraumatischen Hirnblutung, spielt es keine große Rolle, ob die Betroffenen zuvor direkt wirksame orale Antikoagulanzien oder Marcumar bekommen haben: Die Prognose ist ähnlich schlecht.

Thrombektomie auch bei großen Infarkten von Vorteil

16.05.2024 Ischämischer Schlaganfall Nachrichten

Auch ein sehr ausgedehnter ischämischer Schlaganfall scheint an sich kein Grund zu sein, von einer mechanischen Thrombektomie abzusehen. Dafür spricht die LASTE-Studie, an der Patienten und Patientinnen mit einem ASPECTS von maximal 5 beteiligt waren.

Schwindelursache: Massagepistole lässt Otholiten tanzen

14.05.2024 Benigner Lagerungsschwindel Nachrichten

Wenn jüngere Menschen über ständig rezidivierenden Lagerungsschwindel klagen, könnte eine Massagepistole der Auslöser sein. In JAMA Otolaryngology warnt ein Team vor der Anwendung hochpotenter Geräte im Bereich des Nackens.

Schützt Olivenöl vor dem Tod durch Demenz?

10.05.2024 Morbus Alzheimer Nachrichten

Konsumieren Menschen täglich 7 Gramm Olivenöl, ist ihr Risiko, an einer Demenz zu sterben, um mehr als ein Viertel reduziert – und dies weitgehend unabhängig von ihrer sonstigen Ernährung. Dafür sprechen Auswertungen zweier großer US-Studien.
