The purposes of this study were to assess the prevalence of chronic fatigue (CF) in irradiated survivors of non-Hodgkin lymphoma, analyze for associations between hormonal dysfunction and CF, and to investigate the associations between CF and functioning. Invited survivors were all treated with radiation to the head and neck region, with or without additional chemotherapy. The participants (n = 98) responded to questionnaires measuring CF, mental distress (HADS), and functioning (SF-36), and had blood drawn for analyses of four hormonal axes. Hormonal status was categorized as normal, hormone dysfunction in one or more axes, or hormone replacement therapy. A total of 29% of the survivors had CF. In multivariate analyses there was an increased risk of CF among survivors with untreated hormone dysfunction (OR 3.87, 95% CI: 1.20-12.51, p = 0.02). Survivors on hormone substitution did not have increased risk for CF compared to survivors with normal hormonal status. CF was significantly associated with reduced functioning. © 2015 Informa UK, Ltd. Source

Systemic inflammation like in sepsis is still lacking specific diagnostic markers and effective therapeutics. The first line of defense against intruding pathogens and endogenous damage signals is pattern recognition by e.g., complement and Toll-like receptors (TLR). Combined inhibition of a key complement component (C3 and C5) and TLR-co-receptor CD14 has been shown to attenuate certain systemic inflammatory responses. Using DNA microarray and gene annotation analyses, we aimed to decipher the effect of combined inhibition of C3 and CD14 on the transcriptional response to bacterial challenge in human whole blood. Importantly, combined inhibition reversed the transcriptional changes of 70% of the 2335 genes which significantly responded to heat-inactivated Escherichia coli by on average 80%. Single inhibition was less efficient (p<0.001) but revealed a suppressive effect of C3 on 21% of the responding genes which was partially counteracted by CD14. Furthermore, CD14 dependency of the Escherichia coli-induced response was increased in C5-deficient compared to C5-sufficient blood. The observed crucial distinct and synergistic roles for complement and CD14 on the transcriptional level correspond to their broad impact on the inflammatory response in human blood, and their combined inhibition may become inevitable in the early treatment of acute systemic inflammation. © 2015 Lau et al.

Placenta | Year: 2012

Objective: At present there is no internationally accepted, clinically easy understandable, comprehensive morphological placental classification. This hampers international benchmarking and comparisons, and clinical research. Study design: Internationally published criteria on morphological placental pathology were collected, standardized and focused into a comprehensive diagnosis category system. The idea was to create a clinically relevant placental pathology scheme related to major pathological processes. A system of nine main diagnostic categories (normal placenta included) was constructed. Pathologists and obstetricians discussed the mutual understanding of the wording in the reporting. The previously published diagnostic criteria were merged, structured and standardized. Through an interobserver correlation study on 315 placentas from intrauterine deaths and 31 controls (placentas from live births) the microscopic criteria in this classification system were tested on user-friendliness and reproducibility. Results: The clinical feedback has been very positive, focusing on the understandability and usefulness in patient follow-up. The interobserver agreement in the microscopic correlation study was in general good. The differences in agreement mainly reflected the degree of preciseness of the microscopic criteria, exemplified by excellent correlation in diagnosing acute chorioamnionitis. Maternal and fetal circulatory disorders need grading criteria and studies are needed to get more insight and clinical correlations of villitis and maturation disorders. Conclusion: The clinically oriented, unifying and simple placental pathology classification system may work as a platform for standardization and international benchmarking. Further research is needed to define diagnostic criteria in staging and grading of some main diagnostic categories. © 2012 Elsevier Ltd. All rights reserved. Source
