Comparative analysis of long versus short co-incubation of gametes on post-insemination outcomes and embryo morphokinetics.

Research Question: Does a short co-incubation of gametes in conventional IVF affect post-insemination outcomes and embryo morphokinetics?

Design: Sibling oocyte randomized pilot study conducted between December 2020 and March 2023. Eligible couples (n = 55) were women aged 18-43 years with BMI 35 km/m or lower and male normal semen parameters. Cumulus oocyte complexes (COC) (six to 12) were randomized in a 1:1:2 proportion in long (16-18 h) or short (2 h) co-incubation IVF exposure and ICSI, respectively.

The First Lugano Workshop on the role of adenomyosis in ART.

Adenomyosis is an important clinical condition with uncertain prevalence, and clinical focus on adenomyosis in patients undergoing assisted reproductive technology (ART) has increased during recent years. Recognizing the limited clinical knowledge on the impact of adenomyosis on ART outcomes, the First Lugano Adenomyosis Workshop was a symposium involving experts in the field of adenomyosis, covering basic research, imaging, surgery and infertility to highlight current advances and future research areas over a wide range of topics related to adenomyosis. Adenomyosis is characterized by altered oestrogen and progesterone signalling pathways.

Private versus funded infertility care: not a challenge but a call for cooperation.

Private medical care has significantly contributed to the advancement of various medical fields. The birth of private IVF groups in the 1990s led to improvements in stimulation protocols, embryo culture, intracytoplasmic sperm injection, vitrification and preimplantation genetic testing. However, infertility is often misunderstood as a disease, leading to low birth rates and a lack of awareness among the general population.

Assessing the clinical value of day 7 blastocysts: a predictive model for preimplantation genetic testing for aneuploidy (PGT-A) cycles.

Purpose: To identify the benefit of extending embryo culture until day (D)7 based on patients and cycle characteristics.

Methods: A retrospective cohort study was conducted including 25,120 blastocysts from 5278 PGT-A autologous cycles between 2017 and 2022. A theoretical cumulative live birth rate (CLBR) was calculated by binomial density function.

Steady morphokinetic progression is an independent predictor of live birth: a descriptive reference for euploid embryos.

Study Question: Can modelling the longitudinal morphokinetic pattern of euploid embryos during time-lapse monitoring (TLM) be helpful for selecting embryos with the highest live birth potential?

Summary Answer: Longitudinal reference ranges of morphokinetic development of euploid embryos have been identified, and embryos with steadier progression during TLM are associated with higher chances of live birth.

What Is Known Already: TLM imaging is increasingly adopted by fertility clinics as an attempt to improve the ability of selecting embryos with the highest potential for implantation. Many markers of embryonic morphokinetics have been incorporated into decision algorithms for embryo (de)selection.

Molecular Testing for Mutation in Moroccan NSCLC Patients: CHU Hassan II-Fez Experience.

Epidermal growth factor receptor () mutation screening in non-small cell lung cancer (NSCLC) is now used to guide treatment decisions to identify patients with positive mutations that predict response to tyrosine kinase inhibitors. This study aimed to explore with a prospective study the current testing practices and the predictive value of mutations in a series of 261 patients with NSCLC. EGFR mutation testing was conducted using 2 different assays: bidirectional Sanger sequencing of polymerase chain reaction (PCR) and real-time PCR on the Rotor-Gene Q instrument.

Undetected, natural conception pregnancies in luteal phase stimulations-case series and review of literature.

Study Question: What is the risk of an undetected natural conception pregnancy during luteal phase ovarian stimulation, and how does it impact the pregnancy's course?

Summary Answer: The risk for an undetected, natural conception pregnancy in luteal phase ovarian stimulation is low and it appears that ovarian stimulation is unlikely to harm the pregnancy.

What Is Known Already: Random start ovarian stimulation appears to be similarly effective as early follicular stimulation start; and it allows ovarian stimulation to be started independent of the cycle day and throughout the cycle, in accordance with the patients' and clinics' schedule as long as there is no intention of a fresh embryo transfer in the same cycle. Starting ovarian stimulation in the luteal phase bears the possibility of an-at the timepoint of stimulation start-undetected, natural conception pregnancy that has already occurred.

A novel antimüllerian gene mutation in a woman with high antral follicle count and extremely low serum antimüllerian hormone levels.

Objective: To report a case with a distinct difference between the ovarian reserve parameters of antimüllerian hormone (AMH) levels, antral follicle count (AFC), and follicle-stimulating hormone levels caused by a novel homozygous missense variant in the exon 1 of the gene [NM_000479.4:c259G>A, p.(Val87Met)].

Ongoing pregnancy rates in single euploid frozen embryo transfers remain unaffected by female age: a retrospective study.

Research Question: Is female age a significant factor in the likelihood of an ongoing pregnancy in single euploid frozen embryo transfers (FET)?

Design: Retrospective study of 1923 single euploid FET cycles in 1464 women, either in a natural cycle or a hormone replacement therapy cycle. The primary outcome was the ongoing pregnancy rate (OPR).

Results: There were 990 (51.

Clinicopathological and prognostic implications of EGFR mutations subtypes in Moroccan non-small cell lung cancer patients: A first report.

Background: Non-small cell lung cancer (NSCLC) remains a significant global health concern, with EGFR mutations playing a pivotal role in guiding treatment decisions. This prospective study investigated the prevalence and clinical implications of EGFR mutations in Moroccan NSCLC patients.

Methods: A cohort of 302 NSCLC patients was analyzed for EGFR mutations using multiple techniques.

An epidermal growth factor receptor compound mutation of L858R with S768I in advanced non-small-cell lung cancer: a case report.

Background: In the current treatment landscape for non-small cell lung cancers, epidermal growth factor receptor-tyrosine kinase inhibitors have emerged as a well-established treatment option for patients with advanced or metastatic disease. This is particularly true for those with commonly occurring epidermal growth factor receptor mutations. However, the therapeutic efficacy of these agents for so-called rare epidermal growth factor receptor mutations, and in particular those characterized by a high degree of complexity, such as double mutations, remains a subject of clinical uncertainty.

The combination of dydrogesterone and micronized vaginal progesterone can render serum progesterone level measurements on the day of embryo transfer and rescue attempts unnecessary in an HRT FET cycle.

Purpose: To evaluate the role of serum progesterone (P4) on the day of embryo transfer (ET) when dydrogesterone (DYD) and micronized vaginal progesterone (MVP) are combined as luteal phase support (LPS) in a hormone replacement therapy (HRT) frozen ET (FET) cycles.

Methods: Retrospective study, including single euploid HRT FET cycles with DYD and MVP as LPS and P4 measurement on ET day. Initially, patients with P4 levels < 10 ng/ml increased MVP to 400 mg/day; this "rescue" was abandoned later.

The Anti-urolithiatic effect of the roots of (falc) Lipsch agonist ethylene glycol and magnesium oxide induced urolithiasis in rats.

Phytotherapy, which involves the use of plant extracts and natural compounds for medicinal purposes, is indeed a promising alternative for managing urinary lithiasis. Many plants have been studied for their potential to prevent and treat kidney stones, and they may offer a more natural and potentially less harmful approach compared to conventional treatments. Additionally, phytotherapy may be more cost-effective.

Do women with severely diminished ovarian reserve undergoing modified natural-cycle in-vitro fertilization benefit from earlier trigger at smaller follicle size?

Objective: To evaluate whether trigger and oocyte collection at a smaller follicle size decreases the risk of premature ovulation while maintaining the reproductive potential of oocytes in women with a severely diminished ovarian reserve undergoing modified natural-cycle in-vitro fertilization.

Methods: This was a retrospective cohort study including women who had at least one unsuccessful cycle (due to no response) of conventional ovarian stimulation with a high dosage of gonadotropins and subsequently underwent a modified natural cycle with a solitary growing follicle (i.e.

Primary sex ratio in euploid embryos of consanguine couples after IVF/ICSI.

Purpose: To assess the primary sex ratio (males-to-females at time of conception) in blastocysts from consanguine couples undergoing IVF/ICSI treatments and its correlation with chromosomal constitution.

Method: A total of 5135 blastocysts were analyzed by preimplantation-genetic testing for aneuploidy (PGT-A) with next-generation sequencing (NGS) from November 2016 to December 2020. From those, a total of 1138 blastocysts were from consanguine couples (CS) and 3997 from non-consanguine couples (NCS).

Association of 'normal' early follicular FSH concentrations with unexpected poor or suboptimal response when ovarian reserve markers are reassuring: a retrospective cohort study.

Research Question: Are basal FSH measurements, when elevated within its normal range, useful for assessing overall ovarian response and predicting unexpected poor or suboptimal ovarian response?

Design: Retrospective cohort study of ovarian stimulation cycles.

Results: A total of 1058 ovarian stimulation cycles (891 first, 167 repeated) were included. Anti-Müllerian hormone (AMH) values were categorized into four (0 to ≤0.

The Clinicopathological Features and Prognostic Significance of HER2-Low in Early Breast Tumors Patients Prognostic Comparison of HER-Low and HER2-Negative Breast Cancer Stratified by Hormone Receptor Status.

Introduction: There has been increased interest in HER2-low breast tumors recently, as these tumors may have distinct clinical and molecular characteristics compared to HER2-negative and HER2-positive tumors. A new nomenclature has been proposed for HER2 1+ and HER2 2+ tumors that are confirmed negative according to fluorescence in situ hybridization (FISH). These tumors are now referred to as HER2-low, and it is thought that they may represent a distinct subtype of breast cancer that warrants further investigation.
