RESULTS Bland-Altman plots revealed increasing error with increasing amounts of wake during the sleep episode. Precision-recall statistics indicate that with less sensitive actigraphy thresholds, episodes identified as "wake" are usually 'wake', but many true episodes of 'wake' are missed. With more sensitive actigraphy thresholds, more episodes of 'wake' are identified, but only some of these are true episodes of 'wake'. CONCLUSIONS In hospitalized patients with TBI and poor sleep, actigraphy underestimates the level of sleep disruption and has poor concordance with PSG-determined sleep. Alternate methods of scoring sleep from actigraphy data are necessary in this population. This article is protected by copyright. All rights reserved. This article is protected by copyright.

Radiation terror, nuclear explosion, as well as accidental exposure to radioactive sources in some industries pose a threat to the life of exposed persons. Studies have been conducted using some low-toxic agents to mitigate radiation toxicity and increase survival probability for exposed people. In the current study, we aimed to show the mitigation of radiation-induced mortality and bone marrow toxicity using postirradiation treatment with melatonin. METHOD Mice whole bodies were exposed to 4 or 7 Gy radiation followed by treatment with melatonin after 24 hours. Survival of mice with or without melatonin, the levels of peripheral cells, transforming growth factor (TGF)-β and 8-hydroxy-2' -deoxyguanosine (8-OHdG) in the bone marrow, as well as the expression of NADPH oxidase (NOX)2 and NOX4 in bone marrow cells were evaluated. RESULTS Whole body irradiation led to mortality 30 days after irradiation. However, melatonin treatment reduced mortality. Irradiation also showed severe reduction of lymphocytes, platelets, and red blood cells. The expressions of NOX2 and NOX4, in addition to TGF-β level, were increased after exposure to radiation. Melatonin ameliorated the increased levels of these factors and improved the number of blood cells. CONCLUSIONS Melatonin showed ability to mitigate radiation-induced hematopoietic system toxicity and also increased survival rate. These results suggest that melatonin could be a potential mitigator for accidental radiation events. © 2020 Wiley Periodicals, Inc.BACKGROUND Indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan (Trp) catabolism have been demonstrated to play an important role in tumor immunosuppression. This study examined the expression and catalytic activity of IDO1 in penile squamous cell carcinoma (PSCC) and explored their clinical significance. METHODS IDO1 expression level, serum concentrations of Trp and kynurenine (Kyn) were examined in 114 PSCC patients by immunohistonchemistry and solid-phase extraction-liquid chromatography-tandem mass spectrometry. The survival was analyzed using Kaplan-Meier method and the log-rank test. Hazard ratio of death was analyzed via univariate and multivariate Cox regression. Immune cell types were defined by principal component analysis. The correlativity was assessed by Pearson's correlation analysis. RESULTS The expression level of IDO1 in PSCC cells was positively correlated with serum Kyn concentration and Kyn/Trp radio (KTR; both P  less then  0.001) but negatively correlated with serum Trp concentration (P =lymphocytes, tumor-associated macrophages, and myeloid-derived suppressor cells; all P  less then  0.001) in PSCC tissues. BTK assay Furthermore, the expression of IDO1 was induced by IFNγ in a dose-dependent manner in PSCC cells. CONCLUSIONS IFNγ-induced IDO1 plays a crucial role in immunoediting and immunosuppression in PSCC. Additionally, serum KTR, an indicator of IDO1 catabolic activity, can be utilized as an independent prognostic factor for PSCC. © 2020 The Authors.

Whether interstitial macrophages (IMs) are also involved in lung tumorigenesis is still unclear. Thus, the aim of this study is to evaluate the role of both AM and IM in the development of EGFR mutant driven lung adenocarcinoma. METHODS We used the EGFR mutant doxycycline-inducible mouse model of lung adenocarcinoma to deplete interstitial or AMs by clodronate-encapsulated liposomes administered intravenously (IV) and intratracheally (IT), respectively. Tumor burden, AMs, and the tumor microenvironment were examined by immunohistochemistry, bronchoalveolar lavage fluid or flow cytometry. RESULTS Clodronate treatment resulted in a significant reduction of tumor burden compared with vehicle liposomes alone. Elimination of AMs resulted in a significant reduction of proliferation compared with IV treatment. However, both treatments resulted in a significantly Immunity, Inflammation and Disease published by John Wiley & Sons Ltd.This study examined the health-related quality of life (HRQoL) and psychological functioning of children and young adults with Gaucher disease, type 1 (GD1). Thirty-two (17 pediatric, 15 young adult) patients with GD1 and one parent completed age-appropriate assessments of HRQoL, emotional, and behavioral health. The HRQoL of children with GD1 was compared with a healthy sample and to children diagnosed with Fabry disease (FD; another lysosomal storage disease), while young adults were compared to a healthy sample and to patients with self-reported chronic illnesses. Children with GD1 reported significantly lower HRQoL across all domains relative to healthy counterparts yet comparable HRQoL compared to children with FD. Young adults reported mildly lower physical functioning than healthy peers, but no differences in HRQoL relative to the chronic illness sample. Parent-reported symptom severity was associated with poorer HRQOL in children but not young adults. Few group differences in psychological functioning were observed, except young children showed more school problems than the normative average and there was a trend toward internalizing symptoms.
