Abstract

Purpose

A symbiotic relationship between ovarian granulosa cells (GC) and the developing oocyte is critical. Genetic modulations in GC’s can lead to reproductive insufficiency, highlighting the role of GC’s in reproductive competence. Utilizing gene expression analyses in cumulus GC’s, we attempt to enhance our understanding of mechanisms that may contribute to poor reproductive capacity in young women with diminished ovarian reserve (DOR).

Methods

We measured gremlin 1 (GREM1) gene expression in GC’s from infertile women <38 years undergoing in vitro fertilization in the context of DOR.

Results

GREM1, a member of the differential screening-selected gene aberrative in neuroblastoma (DAN) family of genes known for its highly regulated expression pattern during folliculogenesis and a downstream effecter of oocyte-derived growth and differentiation factor 9, was down-regulated 3-fold (−3.08) in women with DOR versus control; down-regulation was confirmed by qRT-PCR (−4.02).

Conclusion

This is the first demonstration linking differential expression of Gremlin with etiology of infertility in women.

Ambulantisierung: Erste Erfahrungen mit dem Hybrid-DRG

02.05.2024 DCK 2024 Kongressbericht

Die Hybrid-DRG-Verordnung soll dazu führen, dass mehr chirurgische Eingriffe ambulant durchgeführt werden, wie es in anderen Ländern schon länger üblich ist. Die gleiche Vergütung im ambulanten und stationären Sektor hatten Niedergelassene schon lange gefordert. Aber die Umsetzung bereitet ihnen doch Kopfzerbrechen.

Sind Frauen die fähigeren Ärzte?

30.04.2024 Gendermedizin Nachrichten

Patienten, die von Ärztinnen behandelt werden, dürfen offenbar auf bessere Therapieergebnisse hoffen als Patienten von Ärzten. Besonders gilt das offenbar für weibliche Kranke, wie eine Studie zeigt.

Harninkontinenz: Netz-Op. erfordert über lange Zeit intensive Nachsorge

30.04.2024 Harninkontinenz Nachrichten

Frauen mit Belastungsinkontinenz oder Organprolaps sind nach einer Netz-Operation keineswegs beschwerdefrei. Vielmehr scheint die Krankheitslast weiterhin hoch zu sein, sogar höher als von harninkontinenten Frauen, die sich nicht haben operieren lassen.

Welche Übungen helfen gegen Diastase recti abdominis?

30.04.2024 Schwangerenvorsorge Nachrichten

Die Autorinnen und Autoren einer aktuellen Studie aus Griechenland sind sich einig, dass Bewegungstherapie, einschließlich Übungen zur Stärkung der Bauchmuskulatur und zur Stabilisierung des Rumpfes, eine Diastase recti abdominis postpartum wirksam reduzieren kann. Doch vieles ist noch nicht eindeutig belegt.
