Introduction: Hysterosalpingography (HSG) and hysterosalpingo-foam sonography (HyFoSy) are commonly used tubal patency tests during the fertility work-up. Besides its diagnostic purpose, HSG with oil-based contrast can also be applied for its fertility-enhancing effect, by tubal flushing. HyFoSy is considered as less painful compared with HSG, it lacks exposure to iodinated contrast medium and ionising radiation.

- * The study aimed to determine accurate cut-off values for diagnosing "giant atrium," suggesting the use of indexed volume measurements instead of traditional diameter methods for better assessment.
- * Findings indicate that structural abnormalities in the atria are linked to a higher risk of arrhythmias, but further research is needed to understand the implications of these conditions on serious complications like thromboembolism.
Article Synopsis
- Shortwave-infrared (SWIR) photodetectors are crucial for industries like surveillance and quality control, with organic semiconductors emerging as a promising technology for these applications.
- The performance of organic photodetectors (OPDs) is hindered by trap states in disordered semiconductors, but this research cleverly uses these trap states to enhance SWIR sensitivity through a technique called "trap-doping."
- The study presents a proof-of-concept for a broadband OPD that can detect both visible and SWIR light, showcasing performance that rivals advanced photodetectors and highlighting a novel way to improve photodetection by leveraging inherent material limitations.
Article Synopsis
- The study aims to address the concerns surrounding the safety of MRI scans in patients with abandoned and/or epicardial leads in cardiac devices, which is often avoided due to potential heating issues reported in laboratory settings.
- Researchers conducted a comprehensive review of existing literature, analyzing 21 studies involving 656 patients and their MRI experiences with abandoned or epicardial leads, finding no major adverse cardiac events or severe complications.
- The conclusion suggests that while existing data indicates MRI can be safely performed under strict guidelines for these patients, a careful risk-benefit assessment is needed, especially for those with epicardial leads.
