Prevalence and Clinical Features of Pulmonary Embolism in Pregnancy and Puerperium in the Post-COVID-19 Era.

Objective: Interest in pulmonary embolism (PE) has undergone a renaissance since the emergence of COVID-19 pandemic, but PE researches among pregnant mothers in this post-COVID-19 era remains scarce. This study was conducted to (a) determine PE prevalence rate among pregnant and post-partum women with suspected PE after the COVID 19 pandemic, (b) compare the clinical characteristics, laboratory findings and CT features between the PE and non-PE cohorts, and (c) validate the Pregnancy-Adapted Geneva (PAG) score in our population.

Methods: This retrospective cross-sectional study involved the review of all maternal cases with suspected PE who underwent diagnostic CTPA in year 2022.

Novel treatment vs. standard of care in melanoma-associated leptomeningeal metastases: a systematic review and network meta-analysis.

Background: Melanoma stands out as a prevalent instigator of leptomeningeal disease (LMD) within the realm of cancer. Given the poor prognosis accompanying this condition, ongoing trials are exploring a spectrum of treatment modalities in pursuit of more effective interventions. To ascertain the most effective therapeutic strategies, we aim to compare novel treatments against the current standard of care for melanoma-associated LMD.

Bi-allelic MED16 variants cause a MEDopathy with intellectual disability, motor delay, and craniofacial, cardiac, and limb malformations.

The Mediator complex regulates protein-coding gene transcription by coordinating the interaction of upstream enhancers with the basal transcription machinery at the promoter. Pathogenic variants in Mediator subunits typically lead to neurodevelopmental or neurodegenerative disorders with variable clinical presentations, designated as MEDopathies. Here, we report the identification of 25 individuals from 18 families with bi-allelic MED16 variants who have a multiple congenital anomalies (MCAs)-intellectual disability syndrome.

On-Chip Non-Volatile Reconfigurable Phase Change Topological Photonics.

Programmable on-chip terahertz (THz) topological photonic devices are poised to address the rising need for high-capacity data systems, offering broad bandwidth, minimal loss, and reconfigurability. However, current THz topological chips rely on volatile tuning mechanisms that require continuous power to function. Here, a nonvolatile, programmable THz topological silicon chip is demonstrated that integrates a waveguide-cavity coupled system with phase-change material, GeSbTe (GST), enabling persistent and efficient functionality without constant power input.
