Objective: To evaluate the ovarian response cycles of IVF-ET in patients who previously underwent laparoscopic cystectomy for endometriomas.
Design: Retrospective study with prospective selection of participants and controls.
Setting: Instituto de Ginecología y Fertilidad Buenos Aires, Argentina.
Patient(s): Thirty-nine patients underwent an operation for ovarian endometriomas by atraumatic removal of the pseudocapsule with minimal bipolar cauterization of small bleeders and an IVF-ET cycle (group A) and 39 control patients of similar age underwent an IVF-ET cycle for tubal factor infertility (group B).
Intervention(s): Laparoscopic endometrioma cystectomy, IVF-ET cycle.
Main Outcome Measure(s): E(2) levels, number of gonadotropin ampoules, follicles, oocytes retrieved, number and quality of embryos transferred, and clinical pregnancy rate.
Result(s): There were no differences in all the parameters studied (E(2) levels, number of follicles, oocytes retrieved, number and quality of embryos transferred, and clinical pregnancy rate) except for the number of gonadotropin ampoules needed for ovarian hyperstimulation, which was significantly higher in group A than in group B.
Conclusion(s): Our results indicate that laparoscopic cystectomy for endometriomas is an appropriate treatment since it did not negatively affect the ovarian response for IVF-ET.

Background: LIGHT (oLaparib In HRD-Grouped Tumor types; NCT02983799) prospectively evaluated olaparib treatment in patients with platinum-sensitive relapsed ovarian cancer (PSROC) assigned to cohorts by known BRCA mutation (BRCAm) and homologous recombination deficiency (HRD) status: germline BRCAm (gBRCAm), somatic BRCAm (sBRCAm), HRD-positive non-BRCAm, and HRD-negative. At the primary analysis, olaparib treatment demonstrated activity across all cohorts, with greatest efficacy in terms of objective response rate and progression-free survival observed in the g/sBRCAm cohorts. The authors report final overall survival (OS).

One of the most important targets for natural killer (NK) cell-mediated therapy is the induction of natural killer group 2D ligand (NKG2D-L) expression. APTO253 is a small molecule that selectively kills acute myeloid leukemia (AML) cells, and it has been reported that APTO253 can induce Krüppel-like factor 4 (KLF4) expression and downregulate c-MYC expression. Recently, we discovered a novel role of APTO253 in modulating the NK cell response by inducing surface expression of NKG2D-Ls, especially MHC class I polypeptide-related sequence A (MICA), in AML cells.

Background: Para-phenylenediamine (PPD) is a crystalline solid that belongs to the aromatic amine group, widely used in the manufacturing of various dyes. PPD exhibits toxic effects on female hormone stability, ovarian function, and embryo development. Although studies have shown that PPD exposure can damage oocyte quality in female mice, research on its effects on male reproductive capability, particularly on human sperm quality and function, is limited.

Background: To assess the utility of the TCGA molecular classification of endometrial cancer in a well-annotated, moderately sized, consecutive cohort of Chinese patients with ovarian clear cell carcinoma (OCCC).
Methods: We performed DNA sequencing on 80 OCCC patients via a panel that contains 520 cancer-related genes. The TCGA molecular subtyping method was utilized for classification.

Background: Mycotoxin, a secondary metabolite of fungus, found worldwide and concerning in crops and food, causing multiple acute and chronic toxicities. Its toxic profile includes hepatotoxicity, carcinogenicity, teratogenicity, estrogenicity, immunotoxicity, and neurotoxicity, leading to deleterious impact on human and animal health. Emerging evidence suggests that it adversely affects perinatal health, progeny by its ability to cross placental barriers.
