Abstract

Purpose

Ovarian hyperstimulation syndrome (OHSS) represents a rare but dangerous condition associated with controlled ovarian stimulation (COS) in IVF/ICSI. Over the last decades, many strategies have been introduced into clinical practice with the objective of preventing this potentially life-threatening condition. Among these, the freeze-all policy has gained great popularity, thanks to improvements in vitrification. Nevertheless, not all clinics have adequate skills in vitrification procedures and patients may be dissatisfied with a longer time to pregnancy.

Methods

This study is a systematic review and network meta-analysis of randomized controlled trials comparing different strategies of ovarian stimulation in IVF/ICSI cycles (freeze-all policy, algorithm-based individualization of the starting dose, experience-based individualization of the starting dose, standard dose) in terms of reduction of OHSS, in normal responders.

Results

The results indicate that only the algorithm-based individualization of the starting gonadotropin dose reduces OHSS similarly to the freeze-all strategy.

Conclusion

Albeit in the era of the freeze-all policy, the personalization of the starting gonadotropin dose obtained by the use of algorithms should be pursued as a valid and safe option for IVF.

Starke Menopausensymptome: ein Hinweis auf kognitive Veränderungen?

Stärkere Beschwerden in der Perimenopause sind mit einer reduzierten kognitiven Funktion in den mittleren und späteren Lebensjahren assoziiert. Auch das Verhalten kann sich ändern, wie eine Studie zeigt. Beides steht womöglich für erhöhte Demenzgefährdung.

Was tun, wenn pneumologische Medikamente Psyche und Blutbild verändern?

Arzneimittel für Patienten mit Mukoviszidose oder pulmonaler arterieller Hypertonie wirken offenbar nicht nur auf die Lunge. Was es in der Praxis zu beachten gilt, wurde beim Pneumologie-Kongress erläutert.
