Objective: There is a pressing need to understand the pathogenesis of histologic findings and identify the biomarkers for predicting the histologic severity in lupus nephritis (LN). This study aimed to identify the pathogenic signal pathway and elucidate urinary biomarkers for predicting the presence or severity of histologic findings in LN.
Methods: Urine samples from patients with biopsy-proven active LN were screened for 1,305 proteins using an aptamer-based proteomic assay. The diversity and expansion of individual renal histologic features in LN were quantified to identify the urinary proteins associated with the histologic findings found in each score. Candidate urinary proteins were validated in a validation cohort. Immunohistochemical staining of the renal tissues was performed to clarify the localization of the candidate proteins.
Results: Cluster analysis extracted five histologic subgroups according to their correlations with each histologic finding in LN. Protein groups that correlated with each histologic subgroup revealed a distinct pathogenesis in LN using pathway analyses. Enzyme-linked immunosorbent assay validation revealed that urinary calgranulin B (S100A9), monocyte chemotactic protein 1 (MCP-1), and insulin-like growth factor binding protein 5 (IGFBP-5) levels could specifically predict the presence and severity of active glomerular lesions, interstitial inflammation, and interstitial fibrosis, respectively. Immunohistochemical staining revealed the localization of these proteins in each lesion.
Conclusion: Renal histologic findings may reflect the different pathogeneses involved in each lesion, and estimating the urinary calgranulin B, MCP-1, and IGFBP-5 levels may be useful in predicting the presence and severity of histologic findings in LN.

Importance: Exposure to inflammation from chorioamnionitis places the fetus at higher risk of premature birth and may increase the risk of neurodevelopmental impairments, though the evidence for the latter is mixed.
Objective: To evaluate whether moderate to severe histologic chorioamnionitis (HCA) is directly associated with adverse motor performance, independent of the indirect mediating effects of premature birth.
Design, Setting, And Participants: This prospective, population-based cohort study recruited participants between September 16, 2016, and November 19, 2019, from referral and nonreferral neonatal intensive care units of 5 southwestern Ohio hospitals.

Purpose: Frailty measures are critical for predicting outcomes in metastatic spine disease (MSD) patients. This study aimed to evaluate frailty measures throughout the disease process.
Methods: This retrospective analysis measured frailty in MSD patients at multiple time points using a modified Metastatic Spinal Tumor Frailty Index (MSTFI).

Rosai-Dorfman disease (RDD) is a rare histiocytic disorder that may clinically and histologically resemble IgG4-related disease (IgG4-RD), especially in the presence of IgG4-positive plasma cell infiltration. In this case, a 69-year-old woman with generalized lymphadenopathy, constitutional symptoms, and elevated IgG4 levels was initially suspected to have IgG4-RD based on core needle biopsy. However, further evaluation with excisional lymph node biopsy revealed emperipolesis and S100-positive histiocytes, confirming the diagnosis of RDD.

Purpose: Taenia pisiformis cysticerci have been reported in the female reproductive tract of rabbits, and this parasitosis is known to alter reproductive behavior and reduce embryo implantation; however, tissue-based studies relating the immune system to the implantation site during infection have not been previously addressed. Therefore, our research provides new information on the interaction between pregnancy and parasitic infection.
Methods: This study evaluated the recruitment of immune cells in uterine tissue during T.

Background: Enzyme-linked immunosorbent assay (ELISA) kits for BP180-NC16A use different cutoff levels established for cutaneous bullous pemphigoid (BP). However, in oral mucous membrane pemphigoid (OMMP), circulating antibodies are reported to be less readily detectable than cutaneous BP and there is little evidence that these cut-off levels are suitable for OMMP. This study was performed to explore whether the available cutoff values of anti-BP180-NC16A ELISA used for cutaneous BP are equally effective when applied to OMMP or should benefit from an optimized cut-off value.
