I love this podcast ! I was so grateful juju was able to participate in this study 🙏

The JIMD Podcast, a fortnightly podcast from the Journal of Inherited Metabolic Disease. Features interviews with journal authors discussing recent publications.

Johannes Zschocke, Shamima Rahman, and Carlos Ferreira join hosts James Nurse and Eva Moreva to discuss their recent paper on the ICIMD, a new classification system that eloquently organises all things metabolic. They explain what's included, why it is necessary and just how simple it all is. Interested listeners should also read:  Quo vadis: the re-definition of “inborn metabolic diseases” (https://doi.org/10.1007/s10545-015-9893-x)

Professors Jun Kido, Johannes Häberle and Fanny Mochel discuss their recent work on Urea Cycle Disorders to hi-light the significance of this group of diseases. Jun and Johannes collaborated on a large natural history study in Japan of over 270 patients and Fanny recently reported on a large cohort of adults presenting with disease from 16-86 years of age. All three relate these findings to the first revision of the Guidelines for Management published in 2019.

In our latest podcast, Antonia Ribes, Frederic Tort, and Gerard Muñoz-Pujol discuss CRISPR/Cas9 based technique for the validation of genetic variants requiring just the genetic data.

Blood spots are integral to disease monitoring in PKU, however, there are concerns regarding correlation between capillary and plasma levels and discrepancies arising based on sampling quality and storage. Dr Rachel Carling explains how a volumetric blood collection device presents a cost effective way to improve consistency and reduce rejected samples.

The Journal of Inherited Metabolic Disease Editorial Committee come together to talk about the direction of metabolic medicine, the dangers and potential of AI, impact factors, reviewing papers and their publication hopes for 2024. There's also a little metabolic quiz, allowing you to pit your wits against the committee. Featuring: Shamima Rahman, Matthias Baumgartner, Verena Peters, Marc Patterson, Johannes Zschocke and Sean Froese.

JIMD Editor's Roundtable (2023)

Dr Sander Houten discusses a child with hyperlysinemia diagnosed via newborn screening and whether this reflects a disease or just a metabolic perturbation. This distinction is relevant as inducing this state may be a treatment option in GA1 or pyridoxine dependent epilepsy.

Returning guests, Nina Stolwijk and Dr Carla Hollak, and their colleague Dr Annet Bosch, try to untangle the tricky subject of regulation in nutritional products used as therapies in IMD. They also present a framework for when a food should be considered a medicine.

Lottie Morison joins the podcast to discuss recent insights around speech and language progression and assessment in CLN2 and CLN3 disease. Lottie is the first speech and language pathologist to lead an episode and brilliant exemplifies the multidisciplinary nature of IMD care.

Krista Casazza talks about validating key biomarkers in Niemann-Pick type C and why they are essential for future clinical trials and regulatory approval. The discussion focuses on emerging candidates such as 24-hydroxycholesterol, neurofilament light chain, and calbindin-D, alongside the urgent need for data harmonisation and collaboration across the NPC community.

Professor Saudubray and Professor Garcià-Cazorla discuss their paper from 2019 which proposed a simplified classification of IMD. They discuss the challenges of placing over 1000 diagnoses in one of three categories and the value this provides to clinicians.
