Monitoring M-Protein, Therapeutic Antibodies, and Polyclonal Antibodies in a Multiparametric Mass Spectrometry Assay Provides Insight into Therapy Response Kinetics in Patients with Multiple Myeloma.

Multiple Myeloma (MM) is a hematologic malignancy caused by clonally expanded plasma cells that produce a monoclonal immunoglobulin (M-protein), a personalized biomarker. Recently, we developed an ultra-sensitive mass spectrometry method to quantify minimal residual disease (MS-MRD) by targeting unique M-protein peptides. Therapeutic antibodies (t-Abs), key in MM treatment, often lead to deep and long-lasting responses.

Red blood cell transfusions in neonatal intensive care units: a nationwide observational cohort study.

Objective: To describe the use and nationwide variation of red blood cell (RBC) transfusions in neonatal intensive care units (NICUs) following the introduction of the revised national transfusion guideline in 2019.

Design And Patients: We randomly selected neonates born below 32 weeks' gestation admitted to any NICU in the Netherlands in 2020 to include in our retrospective observational cohort study.

Main Outcome Measures: Main outcome measures were the number of neonates receiving at least one transfusion, and the number of transfusions per transfused neonate.

From movement to mind: Early fine motor skills are associated with cognitive performance at school age in very preterm infants.

Background: Although preterm birth is associated with deficits in both motor and cognitive functioning, the association between early motor skills and cognitive outcomes at a later age remains underexplored.

Aim: To evaluate associations between motor skills at age 5.5 and cognitive functioning at age 8.

Isavuconazole as prophylaxis and therapy for invasive fungal diseases: a real-life observational study.

Background: Isavuconazole is a relatively new antifungal agent indicated for the management of various invasive fungal diseases (IFDs), including invasive aspergillosis. Information on real-world experience with isavuconazole is scarce. This retrospective observational study aimed to describe the usage of isavuconazole in clinical practice with an in-depth evaluation of individual isavuconazole exposure.

Temporal Variation and Persistence of Methane Emissions from Shallow Water Oil and Gas Production in the Gulf of Mexico.

Methane emissions from the oil and gas supply chain can be intermittent, posing challenges for monitoring and mitigation efforts. This study examines shallow water facilities in the US Gulf of Mexico with repeat atmospheric observations to evaluate temporal variation in site-specific methane emissions. We combine new and previous observations to develop a longitudinal study, spanning from days to months to almost five years, evaluating the emissions behavior of sites over time.
