Inter-assay variation and reproducibility of progesterone measurements during ovarian stimulation for IVF. [PDF]

PLoS ONE, 2018
In recent years there is increasing evidence that elevated progesterone levels during ovarian stimulation for IVF / ICSI have a negative impact on the ART-outcome.

GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

Advanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.

Long‐term prognosis is associated with residual disease after neoadjuvant systemic therapy but not with initial nodal status

BJS (British Journal of Surgery), EarlyView., 2020
This long‐term follow‐up study determined survival rates in a Swedish national cohort of 417 patients with breast cancer who all had neoadjuvant systemic therapy (NAST). Sentinel lymph node biopsy (SLNB) was performed before NAST in clinically node‐negative and after NAST in clinically node‐positive patients.

Progesterone Enhances Sensitivity of Ovarian Cancer Cells to SN38 Through Inhibition of Topoisomerase I and Inducing Ferroptosis

Cancer Reports
Background Progesterone rapidly induces ovarian cancer cell death through non‐genomic actions mediated by the membrane progesterone receptor (mPR). Aims We investigated the combined effects of progesterone and SN38, an active metabolite of irinotecan, on

Vaginal progesterone reduces the rate of preterm birth in women with a sonographic short cervix: a multicenter, randomized, double-blind, placebo-controlled trial

Ultrasound in Obstetrics and Gynecology, 2011
Women with a sonographic short cervix in the mid‐trimester are at increased risk for preterm delivery. This study was undertaken to determine the efficacy and safety of using micronized vaginal progesterone gel to reduce the risk of preterm birth and ...

Lactation is Associated with Accelerated Postpartum Pelvic Floor Muscle Recovery in a Pregnant Simulated Birth Injury Model

Advanced Science, EarlyView.
ABSTRACT Healthy pelvic floor muscles (PFMs) are essential for proper pelvic floor function. The biggest risk factor for PFM dysfunction is injury sustained during vaginal childbirth, yet the factors that facilitate or impair PFM recovery from birth injury remain unknown.

Natural Resistance to Ovarian Hyperstimulation Syndrome in Estrildid Finches Reveals Macrophage GPR183 as a Potential Therapeutic Target

Advanced Science, EarlyView.
Ovarian macrophage depletion reverses OHSS resistance in estrildid finches and exacerbates OHSS symptoms in rats. Activating macrophage GPR183 alleviates OHSS by reducing pro‐inflammatory factors, increasing immunomodulatory molecules, remodeling CD44/SDC4‐mediated communication, and restoring immune homeostasis.

Progesterone and preterm birth [PDF]

International Journal of Gynecology & Obstetrics, 2020
AbstractProgestogens (vaginal progesterone and intramuscular 17‐hydroxyprogesterone acetate) are widely recommended for women at high risk of preterm birth. Typical regimens include 17‐hydroxyprogesterone caproate (250 mg intramuscularly weekly), starting at 16–20 gestational weeks until 36 weeks or delivery for women with a singleton gestation and a ...

Reprogramming the Immune Landscape of Inflammatory Breast Cancer

Advanced Science, EarlyView.
Inflammatory breast cancer is the most lethal subtype of breast cancer and is characterized by an immunosuppressive tumor microenvironment (TME) driven by a complex network of immune cells and inflammatory cytokines, contributing to its aggressiveness and treatment challenges. Immune checkpoint inhibitors, either alone or in combination, show potential
