Abstract Introduction Absolute quantification of individual metabolites in complex biological samples is crucial targeted metabolomic profiling. Objectives An inter-laboratory test was performed to evaluate the impact NMR software, peak-area determination method (integration vs. deconvolution) and operator on trueness precision. Methods A synthetic urine containing 32 compounds prepared. One site prepared calibration samples, acquisition. spectra were acquired with two pulse sequences including water suppression used routine analyses. The pre-processed sent other sites where each quantified using internal referencing or external calibration, his/her favourite in-house, open-access commercial tool. Results For 1D measurements solvent presaturation during recovery delay (zgpr), 20 successfully by all processing strategies. Some could not be some methods. TSP, only one half a below 5%. With peak integration about 90% NMRProcFlow module allowed several additional metabolites. number improved for deconvolution tools. Trueness precision significantly different between zgpr- NOESYpr-based 70% variables. Conclusion External better than TSP referencing. Inter-laboratory tests are useful when choosing rationalize choice tools NMR-based profiling confirm value

Several studies described the role small as well complex molecules such metabolites, cytokines, chemokines lipoproteins during in recovered patients. In fact, after SARS-CoV-2 viral almost 10-20% experience persistent post 12 weeks recovery defined long-term COVID-19 (LTCS) or long post-acute (PACS). Emerging evidence revealed that dysregulated immune system persisting inflammation could be one key drivers LTCS. However, how these biomolecules altogether govern pathophysiology is largely underexplored. Thus, clear understanding parameters within integrated fashion predict course would help to stratify LTCS This even allow elucidation mechanistic course.

In recent years, various quantitative and functional magnetic resonance imaging (MRI) sequences have been developed used in clinical practice for the diagnosis of patients with low back pain (LBP). Until now, T2-weighted (T2WI), a visual qualitative evaluation method, has to diagnose intervertebral disc (IVD) degeneration. However, this method limitations terms reproducibility inter-observer agreement. Moreover, T2WI observations do not directly relate LBP. Therefore, new such as T2 mapping, T1ρ MR spectroscopy alternative methods. These MRIs can evaluate anatomical physiological changes IVD degeneration more detail than conventional T2WI. values obtained from these still correlate LBP, there is need widespread use techniques that are specific symptoms pain. paper, we review state-of-the-art methodologies future challenges MRI an diagnostic tool painful discs.
