Although NLR is a simple and easily applicable marker, CA-125 is superior for differentiating endometriomas from other benign ovarian cysts. The combination of these 2 markers improves diagnostic accuracy.

Inflammation plays a key role in the pathogenesis of bronchopulmonary dysplasia (BPD). Fatty acid-binding proteins (FABPs) 4 and 5 regulate the inflammatory activity of macrophages. Whether FABPs 4 and 5 could play a role in the pathogenesis of BPD via the promotion of macrophage inflammatory activity is unknown. This study sought to examine whether the expression levels of FABP4 and FABP5 were altered in bronchoalveolar lavage fluid and lung tissue in a baboon model of BPD. This study also sought to characterize the cell types that express these proteins. Real-time PCR, immunoblotting, immunohistochemistry, and double immunofluorescence were used to examine the expression of FABPs in samples of BPD. Morphometric analysis was used to quantify FABP4-positive peribronchial blood vessels in lung sections. FABP4 was primarily expressed in macrophages in samples of BPD. In addition, FABP4 was expressed in the endothelial cells of blood vessels in peribronchial areas and the vasa vasorum, but not in the alveolar vasculature in samples of BPD. FABP4 concentrations were significantly increased in lungs and bronchoalveolar lavage fluid samples with BPD. An increased density of FABP4-positive peribronchial blood vessels was evident in both baboon and human BPD sections. FABP5 was expressed in several cell types, including alveolar epithelial cells and macrophages. FABP5 concentrations did not show any significant alterations in BPD. In conclusion, FABP4 but not FABP5 levels are increased in BPD. FABP4 is differentially expressed in endothelial cells of the bronchial microvasculature, which demonstrates a previously unrecognized expansion in BPD.

INTRODUCTION: Subclinical inflammation markers play a significant role in hyperemesis gravidarum (HEG). Simple hematological markers such as mean platelet volume (MPV), platelet distribution width (PDW), neutrophil-to-lymphocyte ratio (NLR), red cell distribution width (RDW), plateletcrit (PCT), and platelet-to-lymphocyte ratio (PLR) have been shown to reflect inflammatory burden and disease activity in several disorders. Ketonuria is a parameter used in the diagnosis of severe HEG, but its correlation with disease severity remains controversial. The relationship of subclinical inflammation markers with degree of ketonuria has not been examined previously. In this study, we aimed to determine the diagnostic value of these subclinical inflammation markers and the relationship between these markers and grade of ketonuria in patients with HEG. MATERIALS AND METHODS: A total of 94 pregnant women with a diagnosis of HEG and 100 gestational age-matched healthy pregnant women were enrolled in this retrospective study. MPV, PDW, NLR, PLR, PCT, and ketonuria were calculated and analyzed from complete blood cell counts and total urine analyses. RESULTS: Lymphocyte count was significantly higher in the control group (P < 0,001); NLR and PLR values were significantly higher in the HEG group (P < 0,001). Among inflammation markers, RDW increased significantly (P = 0,008) with an increase in ketonuria in patients with HEG. A statistically significant correlation was found between white blood cell (WBC) and NLR, PLR, PCT. A moderate uphill relationship was observed between NLR and WBC and a weak uphill linear relationship was observed between WBC and PLR and between WBC and PCTCONCLUSIONS: PLR and NLR can be considered effective markers to aid in the diagnosis of HEG. No marker was found to correlate with ketonuria grade except RDW, although the relationship of the severity of ketonuria with severity of disease is controversial. RDW increases as the degree of ketonuria increases.

Background/aim: Nicotinamide N-methyltransferase (NNMT) is an enzyme that is overexpressed in malignancies. NNMT expression has not been previously studied in endometrial cancer (EC). Increased phospho-Akt (pAkt) levels in response to NNMT overexpression have been reported in in vitro studies of different cancer types. We assayed NNMT expression in primary and metastatic high-grade EC and investigated the relationship of NNMT with p53, pAkt, and survival. Materials and methods: NNMT, pAkt, and p53 expressions were assayed in 100 tissue samples of benign endometria, primary EC, and metastatic EC by immunohistochemistry. Results: The NNMT immunoreactivity score was significantly higher in primary high-grade EC than benign endometrial tissue (P = 0.001). NNMT expression in metastatic tissue was significantly higher than in primary cancer (P < 0.001). Metastatic stromal NNMT expression was significantly higher than that of the adjacent tumor and stroma adjacent to the primary tumor. p53 expression in the primary tumor showed a significant positive correlation with omental NNMT and pAkt expression. NNMT expression was also correlated with pAkt expression in metastatic tissue. NNMT overexpression in metastatic tissue was associated with decreased survival (P = 0.039). Conclusion: This study suggests that NNMT may promote cancer progression and that NNMT overexpression is associated with aberrant p53 expression, pAkt, and poor survival. NNMT's role in cancer progression could make it a target of EC therapy.
