Article Synopsis
  • High grade serous ovarian cancer has two metabolic subtypes: a high OXPHOS subtype that is more chemosensitive and a low OXPHOS subtype that relies on glycolysis and is more drug resistant.
  • The low OXPHOS subtype shows higher levels of lactate dehydrogenase and monocarboxylate transporter 4, indicating different metabolic behaviors compared to the high OXPHOS subtype.
  • Two imaging techniques, C magnetic resonance spectroscopy and PET scans, can differentiate between these subtypes and track their treatment responses, offering potential clinical applications for patient management.

Although calcification in the cardiovascular system is highly studied, the mechanisms behind it are not well understood. Current proposed mechanisms focus on cellular processes leading to, or controlling the unwanted mineralization in soft tissues. However, extracellular components such as collagen and elastin fundamentally regulate the mechanical properties of heart tissues.

The Use of 3-Dimensional Modeling and Printing in Corrective Osteotomies of the Malunited Pediatric Forearm: A Systematic Review and Meta-Analysis.

J Am Acad Orthop Surg Glob Res Rev

December 2024

From the Evelina London Children's Hospital, Guy's and St. Thomas' NHS Trust, London, UK (Dr. Fossett and Dr. Afsharpad); the Imperial College London University, South Kensington, London, UK (Dr. Fossett and Dr. Sarraf); and the St. Mary's Hospital, Imperial College Healthcare, London, UK (Dr. Sarraf).

Introduction: Forearm fractures contribute up to 40% of all pediatric fractures, with ≤39% of conservatively managed fractures resulting in malunion. Surgical management of malunion is challenging as precise calculation of multiplanar correction is required to obtain optimal outcomes. Advances in 3D computer modeling and printing have shown promising results in orthopaedics, reducing surgical time, blood loss, and fluoroscopy.

Background: Approximately 15 % of women undergoing assisted reproductive treatment (ART) fall in the category of poor ovarian reserve defined as the retrieval of three or fewer oocytes following conventional ovarian stimulation with a daily gonadotrophin dose of 150-450 international units, according to the Bologna criteria. Low number of oocytes collected is, therefore, likely to translate to low chance of successful ART treatment.

Objectives: The objective of the study was to assess if age and number of oocytes retrieved influence the cumulative live birth rate (LBR) in women with poor ovarian response (POR) to controlled ovarian hyperstimulation.

  • The anti-WNT factor ZNRF3 is crucial for determining gonadal sex, as XY mice lacking it show variable ovarian tissue development during fetal stages.
  • Researchers used single-cell RNA sequencing to investigate how ZNRF3 deficiency affects cell development in the gonads, revealing failures in the proper differentiation of Sertoli and granulosa cells.
  • The study finds that without ZNRF3, there is significant disruption in the expected testicular cell fate, leading to a mix of cellular identities that complicate the traditional understanding of sexual differentiation.

November 2024

National Heart and Lung Institute, Imperial College London, London, UK; Royal Brompton and Harefield Hospitals, Guy's and St Thomas' NHS Foundation Trust, London, UK.

Article Synopsis
  • Intravoxel incoherent motion (IVIM) imaging traditionally has low sensitivity in measuring heart perfusion, prompting the development of a more effective stimulated-echo (STEAM) method for better assessment of cardiac microstructure and perfusion.
  • The new STEAM-IVIM technique collects data at 20 different b-values and 6 diffusion directions, allowing thorough analysis of heart tissue in 20 healthy individuals.
  • The results indicate high-quality imaging with promising IVIM parameters and diffusion tensor metrics, suggesting that this method can detect abnormalities in heart microstructure and perfusion without needing contrast agents.
