Religious involvement is associated with mental health and well-being in non-military populations. This study examines the relationship between religiosity and PTSD symptoms, and the mediating effects of anxiety and depression in Veterans and Active Duty Military (V/ADM). This was a cross-sectional multi-site study involving 585 V/ADM recruited from across the USA. Inclusion criteria were having served in a combat theater and PTSD symptoms. Demographics, military characteristics, and social factors were assessed, along with measurement of religiosity, PTSD symptoms, depression, and anxiety. Bivariate and multivariate analyses examined the religiosity-PTSD relationship and the mediating effects of anxiety/depression on that relationship in the overall sample and stratified by race/ethnic group (White, Black, Hispanic). In bivariate analyses, the religiosity-PTSD relationship was not significant in the overall sample or in Whites. However, the relationship was significant in Blacks (r = - 0.16, p = 0.01) and in Hispanics (r = 0.30, p = 0.03), but in opposite directions. In the overall sample, religiosity was inversely related to anxiety (r = - 0.07, p = 0.07) and depression (r = - 0.21, p < 0.0001), especially in Blacks (r = - 0.21, p = 0.001, and r = - 0.34, p < 0.0001, respectively); however, in Hispanics, religiosity was positively related to anxiety (r = 0.32, p = 0.02) as it was to PTSD symptoms. When anxiety/depression was controlled for in multivariate analyses, the religiosity-PTSD relationship in the overall sample reversed from negative to positive, approaching statistical significance (B = 0.05, SE = 0.03, p = 0.079). In Blacks, the inverse association between religiosity and PTSD was explained by quality of relationships, whereas the positive relationship in Hispanics was explained by anxiety symptoms. In conclusion, religiosity was inversely related to PTSD symptoms in Blacks, positively related to PTSD in Hispanics, and unrelated to PTSD in the overall sample and in Whites. Anxiety/depression partially mediated the relationship in the overall sample and in Hispanics. Although longitudinal studies will be necessary to determine how these relationships come about, consideration should be given to spiritual/religious interventions that target anxiety/depression in V/ADM with PTSD.
- The prognostic significance of Albumin-to-Alkaline Phosphatase Ratio in upper tract urothelial carcinoma. [Journal Article]

To assess the prognostic impact of pretreatment albumin-to-alkaline phosphatase ratio (AAPR) in patients with upper tract urothelial carcinoma (UTUC), the data of 692 patients, operated between 2003 and 2016 in our center, were retrospectively assessed. The threshold of AAPR was defined as 0.58 by using the receiver-operating curve analysis. Overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS) were evaluated using the Kaplan-Meier method. And the univariate and multivariate Cox's regression models were performed to identify independent prognostic predictors. The results showed that AAPR <0.58 was significantly related to higher pT stage and grade, concomitant variant histology, anemia and larger tumor size. Additionally, patients with a lower AAPR had an inferior survival outcomes than those with an AAPR ≥0.58 (all P < 0.001). Multivariate analysis suggested that the lower AAPR was also an independent risk factor for poor OS (HR 1.587, 95%CI: 1.185-2.126; P = 0.002), CSS (HR 1.746, 95%CI: 1.249-2.440; P = 0.001), and RFS (HR 1.337, 95%CI: 1.027-1.739; P = 0.031). Moreover, subgroup analysis demonstrated the lower AAPR was related to worse prognosis in high-grade UTUC patients; but in those with low-grade disease, no relationship between them was observed. In conclusion, our results found that the decreased AAPR was independently related to poor survival outcomes in UTUC patients. Using the AAPR for subclassification of high-grade UTUC seems to further identify a poor prognostic group and contribute to clinical decisions making.

Xanthine oxidase (XO), an isoform of xanthine oxidoreductase (XOR), is thought to increase the cardiovascular burden among chronic kidney disease (CKD) patients via oxidative radical production. Plasma XOR redox, which is characterized by the ratio of XO to total XOR, changes under different oxidative conditions associated with kidney dysfunction. However, the relationship between plasma XOR redox and oxidative stress (OS) is unclear. Thus, we aimed to clarify whether OS is related to XOR redox. We used the redox state of human serum albumin (HSA) as a marker to investigate the status of OS in CKD patients. HSA is composed of human mercaptoalbumin (HMA), which possesses not oxidized cysteine residues, reversibly oxidized human nonmercaptoalbumin-1 (HNA-1), and strongly oxidized human nonmercaptoalbumin-2 (HNA-2). The subjects included 13 nondialysis patients (7 males and 6 females) with varying degrees of kidney function. We found that ƒ(HMA) was negatively (R = -0.692, P = 0.0071) and ƒ(HNA-1) was positively (R = 0.703, P = 0.0058) correlated with plasma XO/XOR. ƒ(HNA-2) showed no correlation with XO/XOR (R = 0.146, P = 0.6412), indicating that plasma XOR redox is not related to the irreversible oxidation of HSA. In conclusion, plasma XOR redox is closely related to HSA redox, particularly reversible oxidation of HSA.

Fabry disease is characterised by neuropathic pain and accelerated vascular disease. This study evaluates the utility of corneal confocal microscopy (CCM) to non-invasively quantify corneal nerve and endothelial cell morphology and dendritic cell (DC) density in relation to disease severity in subjects with Fabry disease. Seventeen consecutive participants with Fabry disease and 17 healthy control subjects were included in this cross-sectional study. Fabry disease severity was measured using the Mainz Severity Score Index (MSSI). Central corneal sensitivity was assessed with a contact corneal esthesiometer. There was a significant reduction in the corneal sensitivity (5.75 [5.25-6.00] vs. 6.00 [6.00-6.00] cm, P = 0.014), nerve fiber density (NFD) (26.4 ± 10.1 vs. 33.7 ± 7.9 fibers/mm2, P = 0.025) and nerve fiber length (NFL) (15.9 ± 3.4 vs. 19.5 ± 4.4 mm/mm2, P = 0.012) and an increase in DC density (38.3 [17.5-97.3] vs. 13.5 [0-29.4] cells/mm2, P = 0.004) in subjects with Fabry disease compared to the healthy control subjects. The total MSSI score correlated with NFD (ρ = -0.686; P = 0.006), NFL (ρ = -0.692; P = 0.006), endothelial cell density (ρ = -0.511; P = 0.036), endothelial cell area (ρ = 0.514; P = 0.036) and α-galactosidase A enzyme activity (ρ = -0.723; P = 0.008). This study demonstrates reduced corneal sensitivity, corneal nerve fiber damage and increased DCs in subjects with Fabry disease.

Atypical RhoV GTPase (Chp/Wrch-2) is a member of the human Rho GTPase family, which belongs to the superfamily of Ras-related small GTPases. The biological functions of RhoV, regulation of its activity, and mechanisms of its action remain largely unexplored. Rho GTPases regulate a wide range of cellular processes by interacting with protein targets called effectors. Several putative RhoV effectors have been identified, including protein kinases of the Pak (p21-activated kinase) family: Pak1, Pak2, Pak4, and Pak6. RhoV GTPase activates Pak1 protein kinase and simultaneously induces its ubiquitin-dependent degradation. Pak1 regulates E-cadherin localization at adherens junctions downstream of RhoV during gastrulation in fish. The effector domain of RhoV mediates its binding to the CRIB (Cdc42/Rac1 interactive binding) motif in the N-terminal p21-binding domain (PBD) of Pak6 protein kinase. The role of the RhoV effector domain in mediating interaction with Pak1 has not been studied. This study has identified mutations in the effector domain of RhoV GTPase (Y60K, T63A, L65A, and D66A) that impair its interaction with Pak1 in the GST-PAK-PBD pull-down assay and coimmunoprecipitation. Our results suggest that the effector domain of RhoV mediates its binding to Pak1, complementing the current view of the molecular basics of RhoV binding to effectors of the Pak family. These data lay the basis for further studies on the role of Pak1 in RhoV-activated signaling pathways and cellular processes.
