With an impending #MRI to make sure my #MultipleSclerosis meds are working on Monday, I’m planning to get everything I can outta this weekend. Mid 60s here we come!

Mit dem PEDNET-LC Netzwerk soll eine einheitliche, bedarfsgerechte Versorgung aufgebaut werden. Ein interdisziplinärer Verbund aus Medizin, Forschung und Betroffenenorganisationen, darunter der Fatigatio e.V., arbeitet zusammen, um Wissen zu bündeln, Forschung voranzutreiben und Versorgungsstrukturen nachhaltig zu verbessern.
Projektleiterin ist Prof. Uta Behrends vom MRI Chronische Fatigue Centrum für junge Menschen (MCFC).

NEW PAPER OUT IN #PEDIATRICRESEARCH
We used quantitative susceptibility mapping (#QSM) to measure cerebral oxygenation in #preterm #neonates 
We explored whether isolating paramagnetic components improved the accuracy in major cerebral veins.

NatureThe application of magnetic susceptibility separation for measuring cerebral oxygenation in preterm neonates - Pediatric ResearchQuantitative susceptibility mapping (QSM), a magnetic resonance imaging (MRI) modality sensitive to deoxyhemoglobin, is a promising method for measuring cerebral oxygenation in human neonates. Paramagnetic sources, like deoxyhemoglobin, however, can be obscured by diamagnetic sources such as water and myelin. This study evaluated whether QSM images, or isolated paramagnetic components, are more accurate for measuring oxygenation of cerebral veins of preterm neonates, and explored oxygenation differences between the major cerebral veins. 19 preterm neonates were scanned on at term equivalent age on a 3T MRI using a multi-echo susceptibility-weighted imaging sequence. Susceptibility values were calculated from QSM images to determine oxygen saturation (SvO2) in the superior sagittal sinus (SSS) and central cerebral veins (CCV). The paramagnetic components of QSM images were isolated, and SvO2 values were recalculated. The mean SvO2 values from QSM were 72.4% (SD, 3.4%) for the SSS and 68.7% (SD, 3.5%) for the CCV. SvO2 values for paramagnetic components were 58.1% (SD, 7.3%) for the SSS and 57.7% (SD, 7.0%) for the CCV. While paramagnetic component decomposition yielded SSS values closer to those found in the literature, it increased variability. No significant oxygenation differences were found between the SSS and CCV, contrasting with prior studies.
I've put together a summary of my recent paper using upright MRI in Perthes' disease - take a look!
Luke Johnson · Research summary: Perthes’ disease and hip impingementChanges to the shape of the hip joint caused by Perthes’ disease are linked to problems such as hip pain and arthritis later in life. But how exactly does deformity result in bad outcomes? One part of my PhD thesis looked into this question, and is available open access in the Journal of Pediatric Orthopaedics as:
Johnson LG, Zhang H, Joseph B, et al. 2024. Anterior hip clearance in residual Legg-Calvé-Perthes disease. J Pediatr Orthop.
Some say that journal articles are like buses...
I'm very happy to announce that two of the chapters from my PhD thesis were just published, within a week of each other!

My ears feel like I’ve been to a very loud rock concert #MRI
I had a brain MRI recently. The report dropped during the night. No sign that the cancer is back.
I've been four years in remission. I entered remission on December 2020 (I don't recall the exact day), after two rounds of chemo (out of 8).

Tanja Schwerdtle, die neue Präsidentin des Max-Rubner-Instituts (#MRI)
Klingt jetzt nicht besonders innovativ.
Zur #Ernährung von Kindern... #Schwerdtle machte deutlich, dass die Gemeinschaftsverpflegung für #Kinder zwar sehr wichtig sei, sie aber von kostenlosen Angeboten wenig halte...
Im Gegensatz zum #Bürgerrat.
Umfangreiche Studien wie die Verzehrstudie des MRI aus dem Jahr 2008 hält Schwerdtle für zu aufwändig.
Und die #Milchindustrie /#Lebensmittel #Lobby
Jammert (typisch und unberechtigt) rum, das sie zu wenig eingebunden wird.
Nix wirklich neues... im #Bundestag

Not really worried about tomorrow's MRI scan as this will the third one I have had. I more worried about what they will find but that is always the case.
It does my anxiety a world of good, not!
