AI Article Synopsis
- Many patients facing recurrent implantation failure (RIF) might benefit from hyaluronic acid (HA) added to the transfer medium during assisted reproductive technology (ART) procedures.
- A study with 248 RIF patients found that while the addition of HA significantly improved clinical pregnancy rates, it did not lead to a higher live birth rate compared to the control group without HA.
- Secondary outcomes related to pregnancy, such as implantation rates and multiple pregnancies, showed no significant differences between the HA and control groups.
Article Abstract
Introduction: Many patients who undergo assisted reproductive technology (ART) suffer from recurrent implantation failure (RIF). The addition of hyaluronic acid (HA) to the transfer medium is one of several methods to improve pregnancy outcomes. We investigated whether HA could improve the live birth and clinical pregnancy rates of RIF patients.
Methods: This study included 248 RIF patients, who were divided into two groups: the control (CTL) group (n=137), which received transfer medium without HA, and the HA group (n=111), which received transfer medium with HA. The two groups were compared according to the ART outcome.
Results: The primary outcomes were the clinical pregnancy and live birth rates. Secondary outcomes include a positive urine pregnancy test, the implantation, ongoing pregnancy, multiple pregnancy, clinical miscarriage, and ectopic pregnancy rates, foetal or congenital defects, obstetric complications, infant birth weight and any related adverse events. Regarding the primary outcomes, the clinical pregnancy rate was significantly higher in the HA group than in the control group, and there was no significant difference in the live birth rate (LBR) between the HA and control groups. Regarding the secondary outcomes, the implantation, multiple pregnancy and ectopic pregnancy rates were similar between the two groups.
Discussion: Our findings supported the conclusion that HA can improve the clinical pregnancy rate of patients with RIF undergoing FET cycles, but the live birth rate was not significantly improved with the addition of HA to the traditional transfer medium.

Silver nanoparticles (AgNPs) are increasingly used in various consumer products and industrial applications, raising concerns about their environmental impact on aquatic ecosystems. This study investigated the physicochemical stability, trophic transfer, and toxic effects of citrate-coated AgNPs in a freshwater food chain including the diatom Cyclotella meneghiniana and the gastropod Lymnaea stagnalis. AgNPs remained stable in the exposure medium, with a minimal dissolution (<0.

The large amounts of attention directed towards the commercialization of renewable energy systems have motivated extensive research to develop non-precious-metal-based catalysts for promoting the electrochemical production of H and O from water. Here, we report promising technology, , electrochemical water splitting for OER and HER. This work used a simple hydrothermal method to synthesize a novel CoTe-FeC nanocomposite directly on a stainless-steel substrate.

Background: Non-metastatic pancreatic ductal adenocarcinoma (PDAC) presents a challenging scenario: the rarity of the disease, the limited number of completed prospective trials, and the shortcomings of comparability across series produce several controversial topics and unanswered questions. Guideline recommendations usually include all the different therapeutic options, de facto transferring to the multidisciplinary team the responsibility on the final decision. This secondary analysis of the GARIBALDI study was aimed to explore the correlation of center type, self-declared volume, and commitment with the overall survival (OS) in patients with non-metastatic PDAC.

Purpose: Supersaturated formulations have been widely explored for improving the oral bioavailability of drugs by using mesoporous silica (MS) to generate supersaturation via molecular adsorption; however, this is followed by precipitation. Several precipitation inhibitors (PI) have been explored to prevent precipitation and maintain the drug in solution for a longer period. However, the combined approach of MS and PIs, the impact of MS and Silica, and the loading of high-molecular-weight neutral molecules such as Cyclosporine A (CsA) have not yet been explored.
