Abstract
INTRODUCTION The American Gastroenterological Association (AGA) has compiled risk factors that may be predictive of disease complications in Crohn's disease (CD) and ulcerative colitis (UC). The aim of this study was to evaluate the performance of the AGA risk factors for risk stratification in UC and CD. METHODS We included participants of 2 cohorts: the Ocean State Crohn's and Colitis Area Registry cohort and the Mayo Clinic cohort. Baseline clinical risk factors were extracted according to the AGA pathway. Our primary end point was defined as follows: (i) any inflammatory bowel disease related-hospitalization, (ii) any inflammatory bowel disease-related bowel surgery, or (iii) any progression of disease. We analyzed the association of the number of AGA risk factors with our end point. Statistical multivariable modeling was performed with Cox proportional hazards model. RESULTS A total of 412 patients with CD were included. Comparing ≥3 risk factors with 0-1 risk factor, we found a significantly increased risk of complications in both the Ocean State Crohn's and Colitis Area Registry cohort (hazard ratio [HR] 2.75, 95% confidence interval 1.71-4.41) and Mayo Clinic cohort (HR 2.07, 95% confidence interval 1.11-3.84). Diagnosis at younger age (HR 2.07), perianal disease (HR 1.99), and B2/B3 behavior (HR 1.92) were significantly associated with disease complications. We did not observe a consistent association between number of risk factors nor any specific individual risk factors and risk of disease complications in the 265 patients with UC included. DISCUSSION We found a significant association between the number of AGA risk factors and the risk of disease complication in CD; this association was not significant in UC. The presence of ≥ 3 risk factors in CD leads to the highest risk of complications. The AGA care pathway is a useful tool to stratify patients who are at higher risk of disease complications in patients with CD.

Abstract
BACKGROUND & AIMS Better biomarkers for prediction of ulcerative colitis (UC) development and prognostication are needed. Anti-integrin αvβ6 (anti-αvβ6) autoantibodies have been described in patients with UC. We tested for the presence of anti-αvβ6 antibodies in the preclinical phase of UC and studied their association with disease-related outcomes after diagnosis. METHODS Anti-αvβ6 autoantibodies were measured in 4 longitudinal serum samples collected from 82 subjects who later developed UC and 82 matched controls from a Department of Defense preclinical cohort (PREDICTS [Proteomic Evaluation and Discovery in an IBD Cohort of Tri-service Subjects]). In a distinct, external validation cohort (Crohn's and Colitis Canada Genetic Environmental Microbial project cohort), we tested 12 pre-UC subjects and 49 matched controls. Furthermore, anti-αvβ6 autoantibodies were measured in 2 incident UC cohorts (COMPASS [Comprehensive Care for the Recently Diagnosed IBD Patients], n = 55 and OSCCAR [Ocean State Crohn's and Colitis Area Registry], n = 104) and associations between anti-αvβ6 autoantibodies and UC-related outcomes were defined using Cox proportional hazards model. RESULTS Anti-αvβ6 autoantibodies were significantly higher among individuals who developed UC compared with controls up to 10 years before diagnosis in PREDICTS. The anti-αvβ6 autoantibody seropositivity was 12.2% 10 years before diagnosis and increased to 52.4% at the time of diagnosis in subjects who developed UC compared with 2.7% in controls across the 4 time points. Anti-αvβ6 autoantibodies predicted UC development with an area under the curve of at least 0.8 up to 10 years before diagnosis. The presence of anti-αvβ6 autoantibodies in preclinical UC samples was validated in the GEM cohort. Finally, high anti-αvβ6 autoantibodies was associated with a composite of adverse UC outcomes, including hospitalization, disease extension, colectomy, systemic steroid use, and/or escalation to biologic therapy in recently diagnosed UC. CONCLUSIONS Anti-integrin αvβ6 autoantibodies precede the clinical diagnosis of UC by up to 10 years and are associated with adverse UC-related outcomes.

Abstract
BACKGROUND Phosphate is indispensable in osteogenesis and mineralization. However, mechanisms by which phosphate enhances osteogenic differentiation are not fully understood. In this study, we studied the effect of phosphate on osteogenic differentiation as well as signaling pathways induced by phosphate in the process. METHOD Induced human bone marrow-derived mesenchymal stem cells differentiation into osteoblasts by the change of media containing β-glycerophosphate (GP), 1 mM inorganic phosphate, or 3 mM inorganic phosphate (Pi). The differentiation of osteoblasts was verified by the expression of osteoblast differentiation markers and calcium deposition. RNA sequencing was performed to assess transcriptome in the early stage of osteogenic differentiation. RESULTS Osteogenic differentiation and mineralization were promoted in the 3 mM Pi group compared to those in the GP and 1 mM Pi groups on day 7 of culture. RNA sequencing revealed that the gene expressions involved in osteogenesis and the components in the Wnt signaling pathway was increased in 3 mM Pi group compared with those in the GP on day 7. Analysis with qPCR and Western blot suggested upregulation of components in the non-canonical Wnt signaling pathway, including WNT5b and phosphorylated-c-Jun in the 3 mM Pi group on day 7. WNT11 mRNA expression was increased in the 2 induction groups on day 7. Inhibition of WNT5b by siRNA experiment attenuated the components in non-canonical Wnt signaling expression, including WNT5b, WNT11 and ROR2 mRNA expression and phosphorylated-c-Jun protein expression. In addition, osteogenic differentiation and mineralization were partly decreased in 3 mM Pi group on day 7 by the inhibition of WNT5b. CONCLUSION Pi promoted osteogenic differentiation through the up-regulation of the non-canonical Wnt signaling pathway, including WNT5b, WNT11, p-c-Jun/c-Jun, in the early stage of differentiation. These findings provide a new perspective into the association of Pi and the non-canonical Wnt signaling pathway during osteogenic differentiation.

Abstract
BACKGROUND Anemia is associated with intensive care unit (ICU) outcomes, but data describing this association in sub-Saharan Africa are scarce. Patients in this region are at risk for anemia due to endemic conditions like malaria and because transfusion services are limited. METHODS This was a prospective cohort study of ICU patients at Kamuzu Central Hospital (KCH) in Malawi. Exclusion criteria included age <5 years, pregnancy, ICU readmission, or admission for head injury. Cumulative incidence functions and Fine-Gray competing risk models were used to evaluate hemoglobin (Hgb) at ICU admission and hospital mortality. RESULTS Of 499 patients admitted to ICU, 359 were included. The median age was 28 years (interquartile ranges (IQRs) 20-40) and 37.5% were men. Median Hgb at ICU admission was 9.9 g/dL (IQR 7.5-11.4 g/dL; range 1.8-18.1 g/dL). There were 61 (19%) patients with Hgb < 7.0 g/dL, 59 (19%) with Hgb 7.0-8.9 g/dL, and 195 (62%) with Hgb ≥ 9.0 g/dL. Hospital mortality was 51%, 59%, and 54%, respectively. In adjusted analyses, anemia was associated with hospital mortality but was not statistically significant. CONCLUSIONS This study provides preliminary evidence that anemia at ICU admission may be an independent predictor of hospital mortality in Malawi. Larger studies are needed to confirm this association.

Abstract
Background:
Hypertension and cognition decline are common problems among mid-aged and elderly populations. We examined the impact of hypertension and its treatment on cognitive function between 2011 and 2015 using the China Health and Retirement Longitudinal Study (CHARLS).
Methods:
A national sample of 10958 mid-aged and elderly Chinese was followed for four years. Hypertension was defined by a mean systolic blood pressure of ≥ 140 mmHg or a mean diastolic blood pressure of ≥ 90 mmHg or by antihypertensive treatment. Cognition was estimated by a composite score of the Telephone Interview of Cognition Status (TICS) (score range: 0-11) and the immediate and delayed recall of 10 simple nouns (score range: 0-10). In linear regression models, the relation between hypertension status, treatment, and cognitive decline over time was examined in different age groups adjusting for baseline cognition score. We further examined the role of selected covariates related to hypertension and cognition, including gender, education level, and residency (rural vs urban).
Results:
Overall cognition scores declined significantly from 11.01(SD: 3.96) in 2011 to 10.24 (SD: 4.29) in 2015 (p < 0.01). For participants aged 55 years and over (n = 6971), the cognition of hypertensive patients who were not aware of their condition (n = 1377) showed a 0.57 point larger decline (p < 0.01) compared to participants without hypertension (n = 4128); patients on antihypertensive treatment (n = 1466) showed a 0.56 point smaller cognition decline (p < 0.01) compared to patients who were not aware of their condition. The cognition decline of patients on antihypertensive treatment was comparable to the decline among non-hypertensive participants, (difference: -0.01 p = 0.96). Results were similar after adjusting for education, gender, and residency. For participants aged 45 to 54 years, there were no differences in cognition decline comparing any of these groups.
Conclusions:
Hypertension may accelerate cognitive decline over a four-year observational period in elderly Chinese but this decline is counteracted by antihypertensive treatment. Efforts to expand medical insurance for hypertension and treatment for the elderly in China may therefore also delay cognition decline in this population.

Abstract
PURPOSE Biomarkers are needed to stratify patients with stage II-III melanoma for clinical trials of adjuvant therapy because, while immunotherapy is protective, it also confers the risk of severe toxicity. We previously defined and validated a 53-immune gene melanoma immune profile (MIP) predictive both of distant metastatic recurrence and of disease-specific survival (DSS). Here, we test MIP on a third independent population. EXPERIMENTAL DESIGN A retrospective cohort of 78 patients with stage II-III primary melanoma was analyzed using the NanoString assay to measure expression of 53 target genes, and MIP score was calculated. Statistical analysis correlating MIP with DSS, overall survival, distant metastatic recurrence, and distant metastasis-free interval was performed using ROC curves, Kaplan-Meier curves, and standard univariable and multivariable Cox proportional hazards models. RESULTS MIP significantly distinguished patients with distant metastatic recurrence from those without distant metastatic recurrence using ROC curve analysis (AUC = 0.695; P = 0.008). We defined high- and low-risk groups based on the cutoff defined by this ROC curve and find that MIP correlates with both DSS and overall survival by ROC curve analysis (AUC = 0.719; P = 0.004 and AUC = 0.698; P = 0.004, respectively). Univariable Cox regression reveals that a high-risk MIP score correlates with DSS (P = 0.015; HR = 3.2). CONCLUSIONS MIP identifies patients with low risk of death from melanoma and may constitute a clinical tool to stratify patients with stage II-III melanoma for enrollment in clinical trials.
