BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is a result of ovarian overexpression of vascular endothelial growth factor (VEGF) and its receptor 2 (VEGFR2). VEGF/VEGFR2 binding disrupts cellular junctions and increases vascular permeability (VP), a characteristic of OHSS, but enhances angiogenesis, which is a fundamental step in implantation. In animals, the dopamine agonist Cabergoline ...

BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is a recognized complication of ovulation induction, occurring in 1-10% of IVF and embryo transfer cycles. While mild OHSS is of no clinical relevance, severe OHSS is a life threatening complication. However, the efficacy of prevalent treatments appeared to be limited. We developed a continuous autotransfusion system with an ultrafiltration in...

Gonadotropin-releasing hormone agonist (GnRHa) trigger instead of human chorionic gonadotropin in the context of ovarian hyperstimulation syndrome (OHSS) prevention has been used for >20 years. In its first decade it did not gain popularity because it cannot work in GnRHa-based ovarian stimulation protocols. The introduction of GnRH antagonists has revolutionized our ability to eliminate OHSS c...

Ovarian hyperstimulation syndrome (OHSS) is potentially life-threatening complication associated with ovarian induction. OHSS is a very rare event in spontaneous pregnancies, most often in situations of multiple or molar gestations, hypothyroidism or polycystic ovary syndrome. We describe a patient with naturally conceived pregnancy associated with spontaneous OHSS complicated by hyperthyroidis...

Abstract Study question What are the underlying mechanisms of EGCG to alleviate Ovary hyperstimulation syndrome (OHSS)? Summary answer inhibited VEGF via TGF-β1 classical-SMAD pathway and 67LR-mediated CREB could reduce ovarian inflammatory effect attenuated OHSS progress in rat model. is known already Ovarian (OHSS) one most severe complications COH during IVF treatment. The pathophysiology ch...

CONTEXT In vitro fertilization (IVF) treatment is an effective therapy for infertility, but can result in the potentially life-threatening complication, ovarian hyperstimulation syndrome (OHSS). OBJECTIVE This study aimed to investigate whether kisspeptin-54 can be used to effectively and safely trigger oocyte maturation in women undergoing IVF treatment at high risk of developing OHSS. SET...

OBJECTIVES To study the nature and extent of evaluation research in occupational health services (OHSs). METHODS Literature review of evaluation research in OHSs. On the basis of a conceptual model of OHS evaluation, empirical studies are categorised into aspects of input, process, output, outcome, and OHS core activities. RESULTS Many methods to evaluate OHSs or OHS activities exist, depen...

Ovarian hyperstimulation syndrome (OHSS) is still a severe complication due to controlled ovarian stimulation for artificial reproductive technology. Even though multiple techniques to avoid OHSS have been discussed in the last decades, up to now no clear concepts for primary and secondary prevention exist. This review gives an overview over proposed strategies to avoid OHSS. In a retrospective...

no family history of cardiovascular disease, no use of oral contraceptive or preventive medication for stroke. She had been nulligravida before this pregnancy. Ultrasonographic examination of the ovaries was performed by the infertility clinic and revealed multiple, bilateral follicles, 0.5–0.7 cm in size. Induction of ovulation began 28 days prior to focal neurological symptoms. The patient re...
