Journal: Progesterone receptors regulate susceptibility to spreading depression. (Pubmed Central) - Jan 30, 2025 PRs were modulated using agonist segesterone and antagonist RU-486...Chemogenetic silencing of PR-expressing somatosensory cortical neurons also reduced the CSD frequency. These findings demonstrate the critical role of progesterone-PR signaling in regulating CSD and enhance our understanding of female hormonal regulation of migraine pathophysiological mechanisms.

Review, Journal: Progesterone signaling in uterine fibroids: Molecular mechanisms and therapeutic opportunities. (Pubmed Central) - Jan 18, 2025 Newer SPRMs, such as vilaprisan, show promise, but further research is necessary to assess the long-term safety and effectiveness. This review discusses the mechanisms by which progesterone contributes to fibroid growth and examines clinical effectiveness of SPRMs as potential treatments for uterine fibroids.

Journal: Treatment of Early Pregnancy Loss With Mifepristone and Misoprostol Compared With Misoprostol Only. (Pubmed Central) - Jan 17, 2025 This review discusses the mechanisms by which progesterone contributes to fibroid growth and examines clinical effectiveness of SPRMs as potential treatments for uterine fibroids. The addition of mifepristone to misoprostol was associated with a significantly lower rate of treatment failure, including late surgical intervention for early pregnancy loss, compared with misoprostol alone.

These include the clinical trajectory of changes made gradually over two decades by the Food and Drug Administration in the United States, the Therapeutic Goods Administration in Australia and Medsafe in New Zealand; evolving attitudes in the community; and the subversive accessibility of "mere pills".

Journal: A descriptive summary of the WHO availability assessments of medical abortion medicines in eight African countries. (Pubmed Central) - Dec 28, 2024 Framings of 'period-like pain' do not clarify expectations and should be avoided. The national landscape assessments identified several cross-cutting opportunities to improve availability of medical abortion medicines, including importing quality-assured medical abortion medicines; developing nationally approved abortion service and delivery guidelines that optimize healthcare worker roles; and expanding communication strategies to reach end-users and pharmacists.

Journal: A glucocorticoid spike derails muscle repair to heterotopic ossification after spinal cord injury. (Pubmed Central) - Dec 18, 2024 We report that spinal cord injury (SCI) triggers a rapid corticosterone spike in mice, which is causal for NHO development because treatments with corticosterone or the synthetic glucocorticoid (GC) receptor (GR) agonist dexamethasone are sufficient to trigger heterotopic ossification and upregulate the expression of osteoinductive and osteogenic differentiation genes in injured muscles even without SCI...Furthermore, administration of clinical GR antagonists inhibits NHO development in mice with SCI. This study identifies endogenous GC as causing pathological NHO after CNS injury and suggests that GR antagonists may be of prophylactic use to prevent NHO development in victims of severe CNS injuries.

Methods, results, and complications (Pubmed Central) - Dec 18, 2024 The incidence of complications after medical termination of pregnancy is comparable to what has been observed in other Nordic countries. Despite a higher risk of incomplete abortion when drugs are used, the benefit of medical therapy over surgery is significant.

Journal: Fetal death: Expert consensus of the French College of Obstetricians and Gynecologists. (Pubmed Central) - Dec 10, 2024 Regarding prevention of fetal death in the general population, it is not recommended to counsel or prescribe rest, aspirin, vitamin A, vitamin D, or micronutrient supplementation; systematically look for nuchal cord during prenatal screening ultrasound; or perform systematic antepartum monitoring by cardiotocography for the sole purpose of reducing the risk of fetal death...Regarding patient management in cases of fetal death, it is recommended that: in the absence of risks for disseminated intravascular coagulation or maternal demise, the patient's wishes regarding the timing between the fetal death diagnosis and labor induction should be considered; return home is possible, according to the patient's wishes; in all situations except maternal life-threatening emergencies, the preferred mode of delivery is vaginal, regardless of previous cesarean section(s); mifepristone 200?mg be prescribed at least 24?h before induction; and perimedullary analgesia be initiated at the start of induction if requested by the patient, regardless of GA...Note that if the cause of fetal death is identified, management should be adjusted on a case-by-case basis. Regarding fetal death in a twin pregnancy, it is recommended that the surviving twin be examined immediately upon fetal death diagnosis; in a dichorionic twin pregnancy, preterm delivery induction is not recommended; in a monochorionic twin pregnancy, the surviving twin should be immediately evaluated for signs of acute fetal anemia, with weekly ultrasound monitoring for the first month, though immediate labor induction is not recommended.

This study first proposes that neuron pyroptosis-induced GnRH pulsatility disruption accounts for the pathogenesis of LPD, and QUE facilitates the pulse secretion of GnRH to boost the spontaneous progesterone secretion by inhibiting NF-?B/NLRP3-mediated neuron pyroptosis, which provides a new therapeutic target and strategy for LPD.

Journal: GR/P300 Regulates MKP1 Signaling Pathway and Mediates Depression-like Behavior in Prenatally Stressed Offspring. (Pubmed Central) - Nov 22, 2024 Interestingly, treatment with a GR antagonist (mifepristone, RU486) increased hippocampal GR levels and decreased MKP1 expression, thereby ameliorating abnormal neurogenesis and depression-like behavior in PNS offspring. In conclusion, our study suggested that the regulation of the MKP1 signaling pathway by GR/P300 is involved in depression-like behavior in prenatal stress-exposed offspring and provides new insights and ideas for the fetal hypothesis of mental health.
