Elevated Fecal Lipocalin-2 Levels During Early Life Are Associated with Maternal Inflammatory Bowel Disease Diagnosis.
Dig Dis Sci

Background: Fecal lipocalin-2 (LCN2) is a biomarker of neutrophil activation, which is elevated in patients with inflammatory bowel disease (IBD); however, its dynamic changes during pregnancy and early life are largely unknown. We characterized LCN2 levels by maternal IBD diagnosis, offspring feeding behavior, and gut microbiota composition.
Methods: In the prospective MECONIUM (Exploring Mechanisms of Disease Transmission In Utero through the Microbiome) study, we analyzed 559 fecal samples from 91 pregnant women with IBD, 78 healthy controls, and their 147 offspring for LCN2 levels at each trimester of pregnancy and multiple time points during early life using linear mixed-effects model and multiple logistic regression analyses.
Circulating extracellular vesicles and neutrophil extracellular traps contribute to endothelial dysfunction in preeclampsia.

Background: Preeclampsia (PE) is a pregnancy complication characterized by hypertension, proteinuria, endothelial dysfunction, and complement dysregulation. Placenta-derived extracellular vesicles (EVs), necessary in maternal-fetal communication, might contribute to PE pathogenesis. Moreover, neutrophil extracellular traps (NETs) play a pathogenic role in other complement-mediated pathologies, and their contribution in PE remains unexplored.

Case Rep Med
December 2024
Department of Surgery, Jimma Medical Center, Jimma University, Jimma, Ethiopia.
Spontaneous hepatic rupture is a rare complication that occurs in pregnant mothers with HELLP syndrome, or preeclampsia with severe features, or eclampsia. The most common symptom of hepatic rupture/hematoma is right upper quadrant pain or epigastric pain, which is similar to the presentation of preeclampsia with severe features. Therefore, the absence of specific signs and symptoms leads to a diagnostic dilemma and a delay in management.

Contemporarily, pulsed mode thulium laser has been reported to confer adequate hemostasis. Therefore, the primary outcome of this study was to assess safety and efficacy of thulium laser-based hemostasis during PNL.

Article Synopsis
- * The study focused on the role of the complement anaphylatoxin C5a in hookworm infection during the early lung stage, revealing that C5aR1 mice had a reduced burden of hookworms and less lung damage compared to regular mice.
- * Results showed that C5aR1 signaling in neutrophils plays a complex role in response to hookworm infections, highlighting an unexpected downside of complement activation in fighting parasites.
