Abstract
BACKGROUND Molecular biomarkers are promising tools to be routinely used in clinical psychiatry. Among psychiatric diseases, major depression disorder (MDD) has gotten attention due to its growing prevalence and morbidity. METHODS We tested some peripheral molecular parameters such as serum mature Brain-Derived Neurotrophic Factor (mBDNF), plasma C-Reactive Protein (CRP), serum cortisol (SC), and the salivary Cortisol Awakening Response (CAR), as well as the Pittsburgh sleep quality inventory (PSQI), as part of a multibiomarker panel for potential use in MDD diagnosis and evaluation of disease's chronicity using regression models, and ROC curve. RESULTS For diagnosis model, two groups were analyzed: patients in the first episode of major depression (MD: n = 30) and a healthy control (CG: n = 32). None of those diagnosis models tested had greater power than Hamilton Depression Rating Scale-6. For MDD chronicity, a group of patients with treatment-resistant major depression (TRD: n = 28) was tested across the MD group. The best chronicity model (p < 0.05) that discriminated between MD and TRD included four parameters, namely PSQI, CAR, SC, and mBDNF (AUC ROC = 0.99), with 96% of sensitivity and 93% of specificity. CONCLUSION These results indicate that changes in specific biomarkers (CAR, SC, mBDNF and PSQI) have potential on the evaluation of MDD chronicity, but not for its diagnosis. Therefore, these findings can contribute for further studies aiming the development of a stronger model to be commercially available and used in psychiatry clinical practice.

Abstract
Pentraxin 3 (PTX3) is a soluble pattern recognition receptor playing an important role in immune response and inflammation. Lipopolysaccharide (LPS) stimulation can significantly induce PTX3 expression and secretion in adipocytes. Appropriate regulation of PTX3 secretion is critical for inflammatory homeostasis. Using chemical inhibitors of conventional and unconventional protein secretion, we explored the mechanisms that control LPS-stimulated PTX3 secretion in 3T3-L1 adipocytes. Inhibiting the conventional protein secretion blocked LPS-stimulated PTX3 secretion, resulting in cellular PTX3 accumulation in adipocytes. We also detected PTX3 in exosomes from LPS-treated adipocytes; inhibiting exosome trafficking attenuated PTX3 secretion. However, only 4.3% of secreted PTX3 was detected in exosomes compared to 95.7% in the non-exosomal fractions. The fractionation of isolated exosomes by the iodixanol density gradient centrifugation confirmed that a small portion of secreted PTX3 overlapped with exosomal markers in small extracellular-vesicle fractions. We conclude that PTX3 is secreted mainly through conventional protein secretion, and a small percentage of PTX3 is released in exosomes from LPS-stimulated adipocytes.

Abstract
Currently, forensic research is multidisciplinary with new methods and parameters useful to define the cause and time of death as well as survival/agony times. The identification of biochemical markers able to estimate agonal period has been studied by many forensic researchers. It is known that the estimation of agonal time in different types of death is not always easy, hence our interest in literature's data. The studies analyzed in this review confirm the important role of thanatobiochemistry for the estimation of survival times. Regardless of the death cause, the survival/agony time between the primary event and death influences markers concentrations in biological samples (e.g., blood, urine, cerebrospinal fluid). Different biomarkers can be used for qualitative evaluations in deaths with short and long agony (e.g., C-reactive protein, ferritin, GFAP, etc.). Instead, the quantitative interpretation showed limits due to the lack of reference cut-offs. Thanatobiochemistry is a useful tool to confirm what emerged from autopsies findings (macroscopic and histological analysis), but further studies are desirable to confirm the evidence emerging from our review of the literature.

Abstract
There are reports that the use of regional anesthesia (RA) may be associated with better perioperative surgical stress response in cancer patients compared with general anesthetics (GA). However, the role of anesthesia on the magnitude of the postoperative systemic inflammatory response (SIR) in colorectal cancer patients, within an enhanced recovery pathway (ERP), is not clear.The aim of the present study was to examine the effect of anesthesia, within an enhanced recovery pathway, on the magnitude of the postoperative SIR in patients undergoing elective surgery for colorectal cancer.Database of 507 patients who underwent elective open or laparoscopic colorectal cancer surgery between 2015 and 2019 at a single center was studied. The anesthetic technique used was categorized into either GA or GA + RA using a prospective proforma. The relationship between each anesthetic technique and perioperative clinicopathological characteristics was examined using binary logistic regression analysis.The majority of patients were male (54%), younger than 65 years (41%), either normal or overweight (64%), and were nonsmokers (47%). Also, the majority of patients underwent open surgery (60%) and received mainly general + regional anesthetic technique (80%). On univariate analysis, GA + RA was associated with a lower day 4 CRP (≤150/>150 mg/L) concentration. On day 4, postoperative CRP was associated with anesthetic technique [odds ratio (OR) 0.58; confidence interval (CI) 0.31-1.07; P = .086], age (OR 0.70; CI 0.50-0.98; P = .043), sex (OR 1.15; CI 0.95-2.52; P = .074), smoking (OR 1.57; CI 1.13-2.19; P = .006), preoperative mGPS (OR 1.55; CI 1.15-2.10; P = .004), and preoperative dexamethasone (OR 0.70; CI 0.47-1.03; P = .072). On multivariate analysis, day 4 postoperative CRP was independently associated with anesthetic technique (OR 0.56; CI 0.32-0.97; P = .039), age (OR 0.74; CI 0.55-0.99; P = .045), smoking (OR 1.58; CI 1.18-2.12; P = .002), preoperative mGPS (OR 1.41; CI 1.08-1.84; P = .012), and preoperative dexamethasone (OR 0.68; CI 0.50-0.92; P = .014).There was a modest but an independent association between RA and a lower magnitude of the postoperative SIR. Future work is warranted with multicenter RCT to precisely clarify the relationship between anesthesia and the magnitude of the postoperative SIR.

Abstract
INTRODUCTION Gestational Diabetes Mellitus (GDM) development is related to underlying metabolic syndrome that is associated with elevated complement C3 and C4. Elevated C3 levels have been associated with preeclampsia and the development of macrosomia. METHODS This case-control study included 34 pregnant women with GDM and 16 non-diabetic (ND) women in their second trimester. Complement-related proteins were measured and correlated with demographic, biochemical, and pregnancy outcome data. RESULTS GDM women were older with a higher BMI (p<0.001); complement C3, C4 and Factor-H were significantly elevated (p=0.001, p=0.05, p=0.01, respectively). When adjusted for age and BMI, Complement C3 (p=0.04) and Factor-H (p=0.04) remained significant. Partial correlation showed significant correlation between C4 with serum alanine aminotransferase (ALT) (p<0.05) and 2nd term diastolic blood pressure (p<0.05); Factor-H and C-reactive protein (CRP; p<0.05). Pearson bivariate analysis revealed significant correlations between C3, C4, and Factor-H and CRP; p<0.05; C3 and gestational age at delivery (GA; p<0.05); C4 and ALT and second-trimester systolic blood pressure (STBP) (p=0.008 and p<0.05, respectively); Factor-H and glycated hemoglobin (HbA1c) (p<0.05). Regression analysis showed that the elevation of C3 could be accounted for by age, BMI, GA and CRP, with CRP being the most important predictor (p=0.02). C4 elevation could be accounted for by ALT, CRP and STBP. CRP predicted Factor-H elevation. CONCLUSION The increased C3, C4 and Factor-H during the second trimester of pregnancy in GDM are not independently associated with GDM; inflammation and high BMI may be responsible for their elevation. The elevation of second trimester C3 in GDM is associated with earlier delivery and further work is needed to determine if this is predictive.

Abstract
BACKGROUND Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is a novel coronavirus that has caused a worldwide pandemic. The majority of medullary thyroid cancers present as a thyroid nodule. At the time of diagnosis, cervical lymph nodes and distant metastases are frequently detected. CASE REPORT Here, we present a case of a 46-year-old man with coronavirus disease (COVID) pneumonia, who had persistently high serum procalcitonin levels despite normal C-reactive protein levels. The attending infectologist happened to be a colleague who spent some time, as part of her internal medicine rotation, in the Endocrine Ward and recalled that medullary thyroid cancer might be the cause. This led to the timely workup and treatment of the medullary cancer.

Abstract
BACKGROUND Zinc (Zn) is a trace metal that is considered to have an impact on chronic inflammation. However, findings of clinical trials have been inconsistent. The present systematic review and meta-analysis aimed to provide a more robust examination of the evidence on the effectiveness of Zn supplements on markers of inflammation and oxidative stress. METHODS A systematic search in PubMed, Scopus, Web of Science and Cochrane Library was undertaken to identify relevant randomized controlled trials (RCTs) assessing the impact of Zn on inflammation and oxidative stress until 17 August 2020. We applied a random-effects method to obtain effect sizes (ES) and 95% confidence intervals (CIs). Meta-regression was used to detect the potential source of between-study heterogeneity. RESULTS Twenty-one eligible RCTs comprising 1321 participants were included in the meta-analysis. In comparison with the control groups, serum C-reactive protein (CRP) (ES = -0.92 mg/L, 95% CI = [-1.36, -0.48], P < 0.001, I2 = 90.2%), tumor necrosis factor-alpha (TNF-α) (ES = -0.49 pg/mL, 95% CI = [-084, -0.14], P = 0.006, I2 = 34.6%) and malondialdehyde (MDA) (ES = -0.42, 95% CI = [-083, -0.01], P = 0.04, I2 = 76.1%) were significantly reduced in the groups receiving Zn. Serum interleukin 6 (ES = -1.02 pg/mL, 95% CI = [-2.06, 0.02], P = 0.05, I2 = 92.3%) was marginally reduced following Zn supplementation. Moreover, treatment duration was found as the source of inter-study heterogeneity. CONCLUSION This meta-analysis suggests that Zn supplements reduce serum concentrations of markers of inflammation and oxidation: CRP, TNF-α and MDA.

Abstract
Pentraxin-3 (PTX3) belongs to the pentraxine family, innate immune regulators involved in angiogenesis, proliferation and immune escape in cancer. Here, we evaluated PTX3 tissue expression and serum levels as biomarkers of clear cell renal cell carcinoma (ccRCC) and analyzed the possible role of complement system activation on tumor site. A 10-year retrospective cohort study including patients undergoing nephrectomy for ccRCC was also performed. PTX3 expression was elevated in both neoplastic renal cell lines and tissues, while it was absent in both normal renal proximal tubular cells (HK2) and normal renal tissues. Analysis of complement system activation on tumor tissues showed the co-expression of PTX3 with C1q, C3aR, C5R1 and CD59, but not with C5b-9 terminal complex. RCC patients showed higher serum PTX3 levels as compared to non-neoplastic patients (p<0.0001). Higher PTX3 serum levels were observed in patients with higher Fuhrman grade (p<0.01), lymph node (p<0.0001), and visceral metastases (p<0.001). Patients with higher PTX3 levels also showed significantly lower survival rates (p=0.002). Our results suggest that expression of PTX3 can affect the immunoflogosis in the ccRCC microenvironment, by activating the classical pathway of CS (C1q) and releasing pro-angiogenic factors (C3a, C5a). The up-regulation of CD59 also inhibits the complement-mediated cellular lysis.

Abstract
Osteoporosis is a chronic, progressive disease in which early diagnosis is very important. The neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) have been reported as new predictors in inflammatory and immune diseases including osteoporosis. No studies have reported the relationship between monocyte-to-lymphocyte ratio (MLR) and osteoporosis patients.To investigated the ability of MLR to predict osteoporosis.Three hundred sixteen osteoporosis patients and 111 healthy control subjects were enrolled. Patients' laboratory and clinical characteristics were recorded. MLR, NLR, and PLR levels were calculated. The differences were compared and the diagnostic values of MLR were analyzed.There were 76 male and 105 female patients included, with a mean age of 56.57 ± 9.95 years. The levels of MLR, NLR, and PLR in osteoporosis patients were all higher than those in healthy control subjects. The area under the curve of MLR was higher than those of NLR and PLR. Multivariate linear regression analysis showed that T-score was affected by age and MLR. MLR was positively correlated with C-reactive protein, erythrocyte sedimentation rate, red blood cell distribution width, age, sex, and inversely with hemoglobin. MLR and PLR levels were significantly higher in osteoporosis patients than in osteopenia patients (P < .05).The present study shows that MLR had a higher diagnostic value for osteoporosis. MLR may be a reliable, inexpensive, and novel potential predictor of osteoporosis.

Abstract
Gabapentin (GPT) has become an emerging contaminant in aquatic environments due to its wide application in medical treatment all over the world. In this study, embryos of zebrafish were exposed to gabapentin at realistically environmental concentrations, 0.1 μg/L and 10 μg/L, so as to evaluate the ecotoxicity of this emergent contaminant. The transcriptomics profiling of deep sequencing was employed to illustrate the mechanisms. The zebrafish (Danio rerio) embryo were exposed to GPT from 12 hpf to 96 hpf resulting in 136 and 750 genes differentially expressed, respectively. The results of gene ontology (GO) analysis and the Kyoto encyclopedia of genes and genomes (KEGG) pathway analysis illustrated that a large amount of differentially expressed genes (DEGs) were involved in the antioxidant system, the immune system and the nervous system. RT-qPCR was applied to validate the results of RNA-seq, which provided direct evidence that the selected genes involved in those systems mentioned above were all down-regulated. Acetylcholinesterase (AChE), lysozyme (LZM) and the content of C-reactive protein (CRP) were decreased at the end of exposure, which is consistent with the transcriptomics results. The overall results of this study demonstrate that GPT simultaneously affects various vital functionalities of zebrafish at early developmental stage, even at environmentally relevant concentrations.

Abstract
Individuals' social experiences are associated with their mental health, physical health, and even mortality. Over the last 30 years, researchers have examined the ways in which these social experiences might be associated with chronic inflammation - a component underlying many of the chronic diseases of aging. Little research, however, has examined the role of adults' attachment style as a specific social component that might be associated with inflammation. In the present study, we utilized data from a sample of 59 African-American adults from the Maryland Adolescent Development in Context Study (MADICS) to examine the links between attachment avoidance and attachment anxiety and C-reactive protein (CRP) and interleukin (IL)-6. After controlling for demographic characteristics, body mass index, and depressive symptoms, attachment avoidance and anxiety were associated with IL-6 but not CRP. This study adds to the growing body of research identifying the wide range of social experiences associated with inflammation and further suggests that attachment relationship experiences may have implications for biological processes relevant to many chronic diseases of aging.

Abstract
C-reactive protein (CRP) acts as a biomarker reflecting different degrees of inflammation. Accumulating reports have suggested that there is a close relationship between CRP and various cancers. However, the influence of CRP on the development of tongue squamous cell carcinoma (TSCC) remains unclear. The purpose of this study was to investigate the role of CRP in TSCC. The results of immunohistochemical staining and statistical analyses showed that CRP expression was associated with TSCC tumor size, lymph node metastasis and pathological differentiation. Cell Counting Kit-8 (CCK-8) assay revealed that CRP could enhance TSCC cell proliferation in a dose- and time-dependent manner. Moreover, with CRP stimulation, proliferating cell nuclear antigen (PCNA) expression patterns presented a notable time-dependent up-regulation. In addition, CRP could enhance the invasion and migration of TSCC cells, as revealed by transwell and wound-healing assays, respectively. Annexin V-FITC/PI staining showed that CRP could protect TSCC cells from starvation- and drug-induced apoptosis. With CRP stimulation, the protein expression levels of phosphorylated protein kinase B (pAkt), phosphorylated mammalian target of rapamycin (pmTOR) and phosphorylated S6 ribosomal protein (pS6) were significantly increased, as demonstrated by western blot analysis. Our data suggest that CRP may play an important role in the development of TSCC. Moreover, the biological effects of CRP on TSCC cells might be related to Akt, mTOR, and S6.

Abstract
Background Leptin, apart from the regulation of food intake, has been implicated in hematopoiesis, the immune response and angiogenesis. Leptin has been found to be decreased in various hematological malignancies. In the present study leptin was measured in multiple myeloma (MM) patients before and after treatment and correlated with other angiogenic molecules and markers of disease activity. Methods Serum leptin, vascular endothelial growth factor (VEGF), basic fibroblast growth factor (b-FGF), interleukin-1 beta (IL-1β), beta 2 microglobulin (β2M) and C-reactive protein (CRP) were measured in 62 newly diagnosed MM patients, 22 of whom obtaining disease stabilization after treatment. The same parameters were measured in 20 healthy controls. Disease stage was defined according to the Durie-Salmon criteria. Results Leptin, VEGF, b-FGF, IL-1β, and β2M were significantly higher in newly diagnosed MM patients than in controls (p<0.05). VEGF, b-FGF, IL-1β, β2M, CRP but not leptin increased with advancing stage of disease (p<0.01). All parameters decreased significantly following treatment (p<0.001). Although IL-1β correlated positively with VEGF, β2M, b-FGF and CRP, leptin did not correlate with any of the measured parameters. Conclusion Leptin serum levels do not reflect disease severity in MM. However, there seems to be a decrease in leptin following treatment, which may be associated with an alteration in the metabolic state or the chemokine milieu.

Abstract
OBJECTIVE To examine the effect of infection with Enterovirus (EV) in children with type 1 diabetes (T1D) on the activities of serum antioxidant enzymes in diabetic and nondiabetic controls. SUBJECTS AND METHODS Three hundred and eighty-two diabetic and 100 nondiabetic children were tested for EV RNA using reverse transcriptase (RT)-PCR. The activities of serum superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) were also estimated in diabetic patients infected with EV (T1D-EV+), those not infected with EV (T1D-EV-), and in nondiabetic controls. RESULTS The frequency of EV was higher in diabetic children (100/382; 26.2%) than in healthy controls (0/100). Levels of fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c) and C-reactive protein (CRP) were significantly higher but C-peptide was significantly lower in diabetic children than in controls. CRP levels were higher in the T1D-EV+ group than in the T1D-EV- group, and higher in all diabetic children than in nondiabetic controls. The activities of the antioxidant enzymes GPx, SOD, and CAT decreased significantly in diabetic children compared to in controls. Moreover, the activities of the enzymes tested were significantly reduced in the T1D-EV+ group compared to in the T1D-EV- group. CONCLUSION Our data indicate that EV infection correlated with a decrease in the activity of antioxidant enzymes in the T1D-EV+ group compared to in the T1D-EV- group; this may contribute to β cell damage and increased inflammation.

Abstract
BACKGROUND C-reactive protein (CRP) has been shown to be associated with several tumors. However, its association with nasopharyngeal carcinoma (NPC) is not well characterized. We performed a literature review and meta-analysis to assess the prognostic relevance of elevated CRP levels in patients with NPC. METHODS A literature search for relevant studies was performed on PubMed (Medline), the Cochrane Library, and Web of Science databases. Hazard ratios (95% confidence intervals) were calculated to assess the association between elevated CRP levels and survival outcomes. RESULTS Five studies with a combined study population of 5215 patients with NPC were included. Pooled hazard ratios for overall survival and distant metastasis-free survival were 1.84 (95% CI = 1.57-2.17) and 1.81 (95% CI = 1.53-2.14), respectively. Subgroup analyses showed that types of indicators and treatment before inclusion had no significant impact on the observed association. CONCLUSION Elevated serum CRP levels in patients with NPC were associated with worse prognosis.

Abstract
Chronic low-grade inflammation plays an important role in the pathogenesis of insulin resistance. In the current study, we tested the effects of salsalate, a non-steroidal anti-inflammatory drug, in an animal model of inflammation and metabolic syndrome using spontaneously hypertensive rats (SHR) that transgenically express human C-reactive protein (SHR-CRP rats). We treated 15-month-old male transgenic SHR-CRP rats and nontransgenic SHR with salsalate (200 mg/kg/day) mixed as part of a standard diet for 4 weeks. A corresponding untreated control group of male transgenic SHR-CRP and SHR rats were fed a standard diet without salsalate. In the SHR-CRP transgenic strain, salsalate treatment decreased circulating concentrations of the inflammatory markers TNF-α and MCP-1, reduced oxidative stress in the liver and kidney, increased sensitivity of skeletal muscles to insulin action and improved tolerance to glucose. In SHR controls with no CRP-induced inflammation, salsalate treatment reduced body weight, decreased concentrations of serum free fatty acids and total and HDL cholesterol and increased palmitate oxidation and incorporation in brown adipose tissue. Salsalate regulated inflammation by affecting the expression of genes from MAPK signalling and NOD-like receptor signalling pathways and lipid metabolism by affecting hepatic expression of genes that favour lipid oxidation from PPAR-α signalling pathways. These findings suggest that salsalate has metabolic effects beyond suppressing inflammation.

Abstract
OBJECTIVE This study investigates the associations of body mass index (BMI) and waist circumference (WC) with markers of systemic inflammation in midlife by race and gender. DESIGN Data were obtained from the Survey of Midlife in the United States, a cross-sectional, observational study of Americans 35 years old or older (White men: N = 410; White women: N = 490; Black men: N = 58; Black women: N = 117). Inflammation was measured by concentrations of fibrinogen and C-reactive protein (CRP) in fasting plasma and concentrations of E-selectin and interleukin-6 (IL-6) in fasting serum. Anthropometric data were used to obtain BMI and WC. Socio-demographic and health-related factors were assessed with a survey. Multivariate models by race and gender were estimated to test the roles of BMI and WC for each inflammation marker. RESULTS Compared to White men, Black women have higher BMI and higher levels of all four inflammation markers; White women have lower BMI, lower WC, and lower E-selectin and fibrinogen but higher CRP; and Black men have higher fibrinogen. After adjusting for socio-demographic and health-related covariates as well as perceived discrimination, WC is associated with all four markers of inflammation among White men and women; with three markers (fibrinogen, CRP, and IL-6) of inflammation among Black women; and with CRP (and marginally with fibrinogen and E-selectin) among Black men. BMI is associated with higher CRP and fibrinogen among Black men (marginally so for White men) but not for women of either race. CONCLUSIONS WC shows more consistent associations with inflammation markers than BMI, although the relationships vary by inflammation marker and population group. Our findings suggest that WC is a risk factor for systemic inflammation among White and Black men and women, and BMI is an additional risk factor for Black men.

Abstract
Background: Micronutrient deficiencies may occur in patients with malignancy due to a variety of possible causes, including unbalanced dietary intake and adverse effects of treatment. In addition, many patients show signs of a chronic inflammatory response, which can affect circulating concentrations of certain vitamins and trace elements. Our aim was to examine the effect of the inflammatory response, as determined by plasma C-reactive protein (CRP) concentrations, on a range of micronutrients in patients with malignancy. Methods: Blood samples were collected from 50 patients with various malignancies for the measurement of vitamins A, E, C and B1, the trace elements copper, zinc, selenium and manganese and the inflammatory marker CRP. Vitamin A was measured as retinol and vitamin E as α-tocopherol. Vitamin C measurement included both ascorbic acid and dehydroascorbic acid. The vitamins were assayed by high-performance liquid chromatography and the trace elements by atomic-absorption spectroscopy. Results: Concentrations of zinc and selenium below their respective reference ranges and copper and manganese above their respective reference ranges were commonly found in the cancer group. However, none of these elements showed any significant correlation with CRP ( P >0.01). Reduced levels of vitamin A, C and B1 were commonly found in the cancer group. Vitamins A and C showed a significant negative correlation with CRP ( rs=-0.66, P <0.0001 and rs=-0.53, P = 0.0005, respectively). Vitamin E showed no correlation with CRP. Conclusion: The inflammatory response is a major consideration in the interpretation of vitamin A and C concentrations in patients with malignancy.

Abstract
Chronic inflammation is a major cause of morbidity and mortality in end-stage renal disease. The associated anemia in these patients due to renal cortical atrophy and erythropoietin deficiency is treated with recombinant erythropoietin. Recent reports suggest a growing incidence of symptomatic venous thrombosis in cancer patients treated with recombinant erythropoietin. Several investigators have reported on different mechanisms of thrombosis in these patients. We hypothesize that thrombosis in patients with end-stage renal disease due to increased expression of C-reactive protein (CRP) as a result of chronic inflammation promotes the release of thrombin activatable fibrinolytic inhibitor causing fibrinolytic deficit and eventually thrombosis. Furthermore, because endothelial nitric oxide is responsible for the maintenance of the normal vascular function, the decreased levels of nitric oxide in chronic inflammation cause endothelial damage and result in thrombosis. To test this hypothesis, blood samples were collected from 106 patients (49 male and 57 female, aged 59.8±15.7 years) with end-stage renal disease undergoing hemodialysis and treated with recombinant erythropoietin at a mean dose of 201.8 U/kg/week. Blood samples were drawn in 5-mL tubes containing 3.2% sodium citrate just before the hemodialysis procedure. These blood samples were immediately centrifuged to obtain platelet-poor plasma, which was aliquoted and frozen at -70°C until further analysis. Erytropoietin antibodies were measured using an anti-EPO enzyme-linked immunosorbent assay (ELISA) method developed in our laboratory. Nitric oxide was measured using a NO analyzer (Sievers 280I, Ionics, Boulder, CO). Plasma CRP levels were measured with a highly sensitive ELISA method IMUNOCLONE CRP ELISA (American Diagnostica, Greenwich, CT). TAFI antigen levels in plasma were analyzed with an IMUCLONE TAFI ELISA kit (American Diagnostica, Greenwich, CT). TAFI functional activity was assayed with an ACTICHROME TAFI activity kit. The measured levels of nitric oxide, CRP, TAFI antigen, and TAFI functional were 37.36±36.8 (normal value, 37.49±18.96; range, 19.3-102 μM), 12.27±10.6 (normal value, < 1 μg/mL), 146.9±28.4% NHP (normal, 100% NHP), and 102.55±37% NHP (normal range, 22.3-165.7; mean, 89.5% NHP), respectively. The erythropoietin antibody was detected in 9.4% of the patient group. While 20% of the erythropoietin antibody-positive and 27.1% of the erythropoietin antibody-negative patients experienced chest pain, thrombotic events developed in 9.4% of the erythropoietin antibody-negative patients. These data provide the rationale for a novel mechanism of thrombosis through increased activity of CRP, nitric oxide, and TAFI, leading to fibrinolytic deficit and thrombosis in patients treated with erythropoietin.

Abstract
In-stent restenosis is a major problem following coronary stent implantation, and inflammation plays an active role. We evaluated the effectiveness of the inflammatory marker C-reactive protein (CRP) as a predictor of in-stent restenosis after successful stent implantation, in 86 patients with unstable angina pectoris. Plasma CRP was measured in all patients before the procedure, and at 48-72 h and 1, 2 and 3 months post-procedure. An angiographic loss of 50% at follow-up was accepted as in-stent restenosis. We found negative and positive predictive values of the pre-procedural plasma CRP for determining 6-month in-stent restenosis of 34% and 61%, respectively. We also found a strong correlation between the 3-month post-procedural CRP value and 6-month in-stent restenosis; the negative and positive predictive values being 8% and 76%, respectively. In conclusion, we showed that a plasma CRP value > 3 mg/l in the third month after coronary stent implantation was a strong predictor of angiographic in-stent restenosis.

Abstract
Inflammation and oxidative and dicarbonyl stress play important roles in the pathogenesis of type 2 diabetes. Metformin is the first-line drug of choice for the treatment of type 2 diabetes because it effectively suppresses gluconeogenesis in the liver. However, its "pleiotropic" effects remain controversial. In the current study, we tested the effects of metformin on inflammation, oxidative and dicarbonyl stress in an animal model of inflammation and metabolic syndrome, using spontaneously hypertensive rats that transgenically express human C-reactive protein (SHR-CRP). We treated 8-month-old male transgenic SHR-CRP rats with metformin (5 mg/kg/day) mixed as part of a standard diet for 4 weeks. A corresponding untreated control group of male transgenic SHR-CRP rats were fed a standard diet without metformin. In a similar fashion, we studied a group of nontransgenic SHR treated with metformin and an untreated group of nontransgenic SHR controls. In each group, we studied 6 animals. Parameters of glucose and lipid metabolism and oxidative and dicarbonyl stress were measured using standard methods. Gene expression profiles were determined using Affymetrix GeneChip Arrays. Statistical significance was evaluated by two-way ANOVA. In the SHR-CRP transgenic strain, we found that metformin treatment decreased circulating levels of inflammatory response marker IL-6, TNFα and MCP-1 while levels of human CRP remained unchanged. Metformin significantly reduced oxidative stress (levels of conjugated dienes and TBARS) and dicarbonyl stress (levels of methylglyoxal) in left ventricles, but not in kidneys. No significant effects of metformin on oxidative and dicarbonyl stress were observed in SHR controls. In addition, metformin treatment reduced adipose tissue lipolysis associated with human CRP. Possible molecular mechanisms of metformin action-studied by gene expression profiling in the liver-revealed deregulated genes from inflammatory and insulin signaling, AMP-activated protein kinase (AMPK) signaling and gluconeogenesis pathways. It can be concluded that in the presence of high levels of human CRP, metformin protects against inflammation and oxidative and dicarbonyl stress in the heart, but not in the kidney. Accordingly, these cardioprotective effects of metformin might be especially effective in diabetic patients with high levels of CRP.

Abstract
OBJECTIVE Hepcidin reduces iron absorption by binding to the intestinal iron transporter ferroportin, thereby causing its degradation. Although short-term administration of testosterone or growth hormone (GH) has been reported to decrease circulating hepcidin levels, little is known about how hepcidin is influenced in human endocrine conditions associated with anemia. RESEARCH DESIGN AND METHODS We used a sensitive and specific dual-monoclonal antibody sandwich immunoassay to measure hepcidin-25 in patients (a) during initiation of in vitro fertilization when endogenous estrogens were elevated vs. suppressed, (b) with GH deficiency before and after 12 months substitution treatment, (c) with hyperthyroidism before and after normalization, and (d) with hyperprolactinemia before and after six months of treatment with a dopamine agonist. RESULTS In response to a marked stimulation of endogenous estrogen production, median hepcidin levels decreased from 4.85 to 1.43 ng/mL (p < 0.01). Hyperthyroidism, hyperprolactinemia, or GH substitution to GH-deficient patients did not influence serum hepcidin-25 levels. CONCLUSIONS In humans, gonadotropin-stimulated endogenous estrogen markedly decreases circulating hepcidin-25 levels. No clear and stable correlation between iron biomarkers and hepcidin-25 was seen before or after treatment of hyperthyroidism, hyperprolactinemia or growth hormone deficiency.

Abstract
Genistein is an isoflavone constituent of soya. This study examined the mechanism by which genistein produced adverse effects in pregnant laboratory rats. Pregnant rats were divided into control (Con) and genistein (Gen) force fed (2 mg/kg) groups. At terminal gestation day (GD) ranging from 0-20, the rats were sacrificed, and blood samples and amniotic fluids were collected. Thyroid hormone, C-reactive protein (CRP) and leptin assay was carried using the blood samples. Leptin was also assayed in the placenta and amniotic fluid supernatant. Oral exposure of pregnant rats to genistein significantly altered maternal T3, (GD18; Con 1.65 ± 0.01, Gen 1.03 ± 0.04 nmol/L), T4 (GD6; Con 29.60 ± 0.00, Gen 36.04 ± 1.29 nmol/L), Leptin (Placenta GD20; Con 0.08 ± 0.01, Gen 0.31 ± 0.02 ng/ml, amniotic fluid ;GD 20; Con 0.02 ± 0.00, Gen 0.35 ± 0.05 ng/ml) in genistein group. These changes were accompanied with loss of embryonic implants and a decrease in fetal and placental weights. The CRP level was significantly decreased and increased at the onset and toward late pregnancy respectively. Oral exposure of pregnant rats to genistein precipitated hypothyroidism, altered some metabolic hormones with a reduction in fetal and placental growth and increased resorption of embryonic implants.

Abstract
Elevated high sensitive C-reactive protein (hsCRP) is a marker for systemic inflammation and a risk marker for atherosclerotic cardiovascular disease (ACVD), and has also been associated with periodontitis. Inter-individual variation for hsCRP in periodontitis has been shown. ANRIL is the strongest genetic susceptibility locus for both periodontitis and ACVD, and it is speculated that genetic variation in ANRIL may modulate inflammatory processes. Therefore, we explored the possible association between hsCRP plasma levels and a leading ANRIL single nucleotide polymorphism (SNP) in periodontitis patients and controls. 171 healthy subjects with North European descent (115 periodontitis and 56 controls) were included in this case-control study. hsCRP levels were determined and subjects were genotyped for the leading ANRIL SNP rs1333048. In a multivariate analysis, periodontitis, female gender, increasing BMI and homozygosity for the major allele (AA-genotype) of rs1333048 were significantly associated with elevated hsCRP plasma levels (p = 0.012, p = 0.004, p = 0.007 and p = 0.003, respectively). Periodontitis patients with rs1333048 AA-genotype showed higher levels of hsCRP than those carrying the minor C allele (median: 4.5 mg/L vs. 1.6 mg/L, padjusted = 0.007). This study is the first to show that, in addition to gender and BMI, also a leading SNP in ANRIL is explanatory for inter-individual variation in hsCRP levels in periodontitis patients of North European descent.

Abstract
BACKGROUND GJA1 and PTX3 were proposed as gene markers for oocyte and embryo developmental competence, while SERPINE2 was reported to be associated with pregnancy outcome. PRSS35, which is exclusively expressed in the ovary, may be correlated with oocyte competence. This study was conducted to evaluate the correlation of cumulus GJA1, PRSS35, PTX3, and SERPINE2 gene expression levels with oocyte maturation, fertilization, and early embryo development. METHODS In total, 308 cumulus cell samples separated from individual cumulus-oocyte complex were obtained from 40 patients undergoing the intracytoplasmic sperm injection treatment procedure. Gene expression levels (mRNA levels) in cumulus cells were assessed using quantitative real-time polymerase chain reaction. RESULTS Gene expression levels of GJA1 and SERPINE2 in cumulus cells surrounding mature oocytes were significantly lower than those in cumulus cells enclosing immature oocytes. PRSS35 mRNA levels in cumulus cells of fertilized oocytes were significantly higher than those in cumulus cells of unfertilized oocytes. GJA1 and SERPINE2 seemed to express higher mRNA levels, while PRSS35 showed lower expression in cumulus cells of oocytes that developed into embryos with good morphology; however, the expression levels of all three genes and PTX3 showed no significant differences between embryos with good or poor morphology. CONCLUSIONS GJA1 and SERPINE2 represent potential gene markers associated with oocyte maturation. PRSS35 may be correlated with oocyte fertilization potential. However, GJA1, PRSS35, PTX3, and SERPINE2 may not be considered as marker genes for predicting embryo morphology.

Abstract
Study Strategy A retrospective clinic study. Purpose To evaluate the efficacy of conservative and surgical treatment for lumbosacral tuberculosis. Methods This study retrospectively reviewed 53 patients with lumbosacral tuberculosis who were treated in our institution between January 2005 and January 2011. There were 29 males and 24 females with average ages of 37.53 ± 17.28 years (range 6–72 years). 11 patients were given only anti-TB drugs; the remainder underwent anterior debridement, interbody fusion with and without instrumentation, or one-stage anterior debridement combined with posterior instrumentation. Outcome data for these patients included neurologic status, lumbosacral angle, erythrocyte sedimentation rate value(ESR) and C-reactive protein value(CRP) were assessed before and after treatment. Results The mean lumbosacral angles were 23.00°± 2.90°in the conservatively treated patients and 22.36°± 3.92o in the surgically treated patients. At the final follow-up, this had improved to 24.10o ± 2.96°in the conservatively treated patients and 28.13° ± 1.93°in the surgically treated patients (all P < 0.05). There were statistically significant differences before and after treatment in terms of ESR and CRP (all P < 0.05). All patients achieved bone fusion. The mean follow-up period was 32.34 ± 8.13 months (range 18 to 55 months). The neurological deficit did not worsen in any of the patients. Conclusions It has been proven that conservative and surgical treatments are safe and effective and produce good clinical outcomes for patients with lumbosacral tuberculosis. The advantages of operation include thoroughness of debridement, decompression of the spinal cord, and adequate spinal stabilization.

Abstract
BACKGROUND Chronic inflammation characterized by the recruitment and activation of macrophages has been implicated in the development of gastric cancer. MATERIALS AND METHODS Expression of the long form of pentraxin-3 (PTX3) in gastric cancer cells was examined by reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay. The migratory capacity of gastric cancer cells and chemotaxis of macrophages by PTX3 were assessed by wound-healing and transwell assays. PTX3 silencing using small interfering RNA (siRNA) was performed to confirm PTX3-mediated effects. RESULTS We demonstrated that PTX3 expression was elevated in human advanced gastric cancer tissues with increased infiltration of CD11b+ macrophages. Tumor necrosis factor-alpha increased PTX3 expression via nuclear factor-kappa B activation in human gastric cancer cells. PTX3 promoted the tumor cell migratory potential, the recruitment of macrophages and their subsequent binding to gastric cancer cells. These effects were suppressed by PTX3 knockdown using siRNA. CONCLUSION Our findings suggest that gastric cancer-derived PTX3 promotes macrophage recruitment, which may contribute to gastric cancer-related inflammation.

Abstract
BACKGROUND The long pentraxin PTX3 is an acute-phase multi-functional protein that might play both positive and detrimental effects under different pathophysiological conditions. We previously showed that statins down-regulate the release of PTX3 in human endothelial cells (ECs). The present study investigated the mechanism mediating this effect, its occurrence in other cells involved in atherogenesis, and whether it takes place in experimental atherosclerosis. METHODS AND RESULTS We found that atorvastatin (1-5 μmol/L) decreased the production and release of PTX3 in human ECs through a post-transcriptional effect. Co-incubation with mevalonate or geranylgeranyl pyrophosphate prevented this effect. Direct blockade of geranylgeranyl transferase I by GGTI-286, treatment with the Rac inhibitor NSC23766 or silencing of the geranylgeranylated GTPase Rac2 by siRNA closely mimicked the action of atorvastatin. In contrast, inactivation of other geranylgeranylated proteins such as RhoA, RhoB, and RhoC or Rac1 did not affect PTX3 release. In addition, we found that atorvastatin also decreased PTX3 secretion in aortic SMCs through a mechanism likely dependent on protein geranylgeranylation, while no effect was observed in monocytes. Finally, we found that atherosclerotic lesions from cholesterol-fed rabbits treated with atorvastatin (2.5 mg/kg/day for 8 weeks) showed less immunoreactive PTX3 than lesions from control animals. CONCLUSIONS Results suggest that statins may interfere with PTX3 expression in vascular cells via inhibition of protein geranylgeranylation. Since PTX3 is increasingly regarded as an important mediator of the inflammatory response underlying atherosclerosis and its complications, these results highlight the need for further studies of the role of PTX3 and its potential pharmacological modulation in cardiovascular disease.

Abstract
PURPOSE Obesity is a major risk factor for several cancers, including female cancers. Endogenous hormones and inflammatory factors may mediate the association between anthropometric measures and cancer risk, although these associations have been studied mainly in Caucasians. The aim of the current study was to explore the association of circulating hormones, adipokines, and inflammatory factors with obesity and overweight in premenopausal Mexican women. METHODS We conducted a cross-sectional analysis of 504 premenopausal women from the large Mexican Teachers' Cohort (MTC, ESMaestras) study to determine the association of insulin-like growth factor I (IGF-I), its major circulating binding protein (IGFBP-3), leptin, adiponectin, C-peptide, and C-reactive protein with comprehensive measures of body size. Biomarkers were measured by immunoassays. Multivariate regression analyses were performed to compare geometric mean biomarker concentrations with measured markers of body size and adiposity. RESULTS Mean IGF-I and IGFBP-3 concentrations significantly increased with increasing height and leg length. Concentrations of IGF-I, adiponectin, and the IGF-I/IGFBP-3 ratio strongly decreased with increasing BMI, weight, waist and hip circumferences, waist-to-hip ratio (WHpR), and waist-to-height ratio (WHtR), while CRP, leptin, C-peptide concentrations, and the leptin/adiponectin ratio strongly increased. Adiponectin and the leptin/adiponectin ratio remained significantly related to measures of central adiposity (waist circumference, WHpR, and WHtR) after adjustment by body mass index. CONCLUSIONS The results of our study suggest a strong relation between biomarkers and body size in this study population and suggest that different fat depots may have different metabolic properties.

Abstract
We herein report the long-term outcome (30 years) of a human immunodeticiency virus- and human herpesvirus 8-negative Japanese man who was diagnosed to have multicentric Castleman disease (MCD) of the plasmacytic type after investigation of generalized lymphadenopathy at 34 of age in 1983. He received chemotherapy based on lymphoma regimens (combinations of prednisolone, vincristine, vindesine, cyclophosphamide, etoposide, melphalan, and ranimustine, etc.) for over 20 years. Although the systemic lymphadenopathy resolved, AA amyloidosis-related nephropathy occurred, with a serum creatinine (Cre) level of 0.9 mg/dL and urinary protein excretion (UP) of 7.5 g daily. Rituximab was started, but Cre increased to 2.6 mg/dL in 2010 and UP was unchanged. Therefore, treatment with tocilizmab was started. As a result, his hypergammaglobulinemia was well controlled, C-reactive protein became normal, UP decreased to 3.5 g daily, and Cre remained at 2.5 mg/dL in 2013. When AA amyloid nephropathy occurred after long-term chemotherapy, lituximab could not control it, but tocilizmab stopped the progression of nephropathy. This case suggests that MCD and AA amyloidosis may both have a close relationship to the overproduction of interleukin-6.

Abstract
Atherosclerosis is a chronic inflammatory disease in the vessel. As a representative inflammatory cytokine, C-reactive protein (CRP) participates in atherogenesis. Although hyperaldosteronism is known to evoke inflammatory response in several tissues and cell types, there is no direct evidence to demonstrate the proinflammatory effect of aldosterone on vascular smooth muscle cells (VSMCs) through CRP. In this study, we observed the effect of aldosterone on CRP expression and the molecular mechanisms in rat VSMCs. The results showed that aldosterone induced CRP expression in VSMCs in vitro and in vivo. Mineralocorticoid receptor (MR) antagonist spironolactone abolished aldosterone-induced CRP expression. In addition, aldosterone stimulated generation of reactive oxygen species (ROS) and activated ERK1/2 phosphorylation, whereas spironolactone inhibited aldosterone-stimulated ROS generation and ERK1/2 phosphorylation. Antioxidant NAC decreased aldosterone-induced CRP expression and ERK1/2 phosphorylation. The further study confirmed that ERK1/2 inhibitor PD98059 and NF-κB inhibitor pyrrolidine dithiocarbamate both depressed aldosterone-induced CRP expression. These demonstrate that aldosterone is able to induce CRP expression via MR-ROS-ERK1/2-NF-κB signal pathway in VSMCs, which provides a new evidence for the proinflammatory and proatherosclerotic effects of aldosterone.

Abstract
Background C‐reactive protein (CRP) binds to damaged cells, activates the classical complement pathway, is elevated in multiple inflammatory conditions, and provides prognostic information on risk of future atherosclerotic events. It is controversial, however, as to whether inhibiting CRP synthesis would have any direct anti‐inflammatory effects in humans. Methods and Results A placebo‐controlled study was used to evaluate the effects of ISIS 329993 (ISIS‐CRPRx) on the acute‐phase response after endotoxin challenge in 30 evaluable subjects. Healthy adult males were randomly allocated to receive 6 injections over a 22‐day period of placebo or active therapy with ISIS 329993 at 400‐ or 600‐mg doses. Eligible subjects were subsequently challenged with a bolus of endotoxin (2 ng/kg). Inflammatory and hematological biomarkers were measured before and serially after the challenge. ISIS‐CRPRx was well tolerated with no serious adverse events. Median CRP levels increased more than 50‐fold from baseline 24 hours after endotoxin challenge in the placebo group. In contrast, the median increase in CRP levels was attenuated by 37% (400 mg) and 69% (600 mg) in subjects pretreated with ISIS‐CRPRx (P<0.05 vs. placebo). All other aspects of the acute inflammatory response were similar between treatment groups. Conclusion Pretreatment of subjects with ISIS‐CRPRx selectively reduced the endotoxin‐induced increase in CRP levels in a dose‐dependent manner, without affecting other components of the acute‐phase response. These data demonstrate the specificity of antisense oligonucleotides and provide an investigative tool to further define the role of CRP in human pathological conditions.

Abstract
MTHFD1 1958G>A, a polymorphism in folate metabolism, increases risk of pregnancy complications. A mouse model exhibited developmental defects, increased weight and decreased leukocyte counts. To examine the latter associations, we genotyped 651 women from a premature birth cohort. Prematurity and 1958G>A were not associated. Increases in the inflammatory marker CRP (logistic regression, p = 0.055) and BMI (chi-square, p = 0.0113) were associated with AA genotype in women with low folate. MTHFD1 1958G>A may influence immune function and obesity.

Abstract
BACKGROUND AND PURPOSE Delirium is thought to be associated with systemic inflammatory response. However, its association with the most widely used inflammatory biomarker C-reactive protein (CRP) has not been well established. We aimed to examine whether CRP on intensive care unit (ICU) entry was associated with subsequent development of delirium. DESIGN AND SETTING This prospective observational study was conducted in a mixed 24-bed ICU in a tertiary teaching hospital. METHODS All patients admitted to the ICU from February 2011 to June 2012 were screened for eligibility. Demographic data and clinical characteristics of included patients were recorded. Patients were screened for the presence of delirium by using the tool Confusion Assessment Method for the ICU (CAM-ICU). C-reactive protein was obtained on ICU entry and 24 hours thereafter. Eligible patients were followed up for 28 days or until death. Univariate and multivariate analyses were performed to evaluate independent risk factors for delirium. Clinical outcome included the length of stay (LOS) in the ICU, 28-day mortality, and duration of mechanical ventilation. Two-tailed P < .05 was considered statistically significant. RESULTS A total of 223 patients were included during study period. In univariate analysis, patients with delirium showed significantly higher CRP values than those without (120.5 vs 57.5 mg/L; P = .0001). By adjusting for confounding variables (including age, sex, Acute Physiology and Chronic Health Evaluation II, intubation, living alone, physical restraint, alcohol drinking, smoking, type of medical condition, and hospital LOS before ICU admission) in logistic regression model, CRP remained an independent predictor of delirium (odds ratio, 1.07; 95% confidence interval, 1.01-1.15). As compared with nondelirious patients, those with delirium showed longer LOS in ICU (13 vs 5 days; P < .001) and duration of mechanical ventilation (6 vs 1 days; P < .001). An increase in CRP greater than 8.1 mg/L within 24 hours was associated with 4-fold increase in the risk of delirium (odds ratio: 4.47, 95% confidence interval, 1.28-15.60). CONCLUSION C-reactive protein measured on ICU entry and its changes within 24 hours are risk indicators of delirium. Further studies exploring the treatment of delirium according to CRP levels are warranted.

Abstract
BACKGROUND Although basic research on neuroimmune interactions suggests that inflammatory processes may play a role in the development of fatigue, population-based evidence on this association is limited. This study examined whether plasma C-reactive protein (CRP) and interleukin-6 (IL-6), biomarkers of systemic inflammation, predict fatigue onset. METHOD The Whitehall II study is a large-scale cohort study conducted in 20 civil service departments in London. Plasma CRP and IL-6 were measured in 4847 non-fatigued participants at phase 3 (1991-1993, aged 39-63 years). Fatigue was assessed using the Vitality subscale of the 36-item Short Form Health Survey (SF-36) at phase 3 and phase 4 (1995-1996). RESULTS During a mean follow-up of 3.1 years, 957 new fatigue cases (19.7%) were identified using the pre-established cut-off score of ≤ 50 on the Vitality subscale. CRP values were dichotomized as low (<1.0 mg/l ) or high (≥ 1.0 mg/l) using the Centers for Disease Control/American Heart Association recommendations. Similarly, IL-6 values were also dichotomized as low (<1.5 pg/ml) or high (≥ 1.5 pg/ml). After full adjustment for sociodemographic and biobehavioral covariates, the odds ratios for new-onset fatigue were 1.28 [95% confidence interval (CI) 1.09-1.49, p = 0.003] for high CRP and 1.24 (95% CI 1.06-1.45, p = 0.008) for high IL-6. Similar results were found when CRP and IL-6 were treated as continuous variables. CONCLUSIONS Plasma CRP and IL-6 were prospectively associated with new-onset fatigue, supporting the hypothesis that low-grade inflammation has a role in the development of fatigue.

Abstract
Visfatin is a newly identified pro-inflammatory adipokine and a genetic polymorphism -1535 C>T located in the visfatin gene promoter has been suggested to be associated with the regulation of visfatin expression in some inflammatory illness. However, there were some conflicting results regarding whether this variant is functional or not. This study aimed to examine the relations of the -1535 C>T single nucleotide polymorphism (SNP) of visfatin gene to the plasma visfatin and C-reactive protein concentrations in traumatic brain injury (TBI). 318 Chinese Han patients with TBI were recruited in this study. Plasma visfatin and C-reactive protein levels were significantly different between the genotypes in the SNP-1535 C>T even after adjustment for age, sex and body mass index. The genotype C-C had the highest plasma visfatin and C-reactive protein concentrations. The plasma visfatin and C-reactive protein concentrations between the variant genotypes C-T and T-T did not differ significantly. Plasma visfatin level was significantly associated with plasma C-reactive protein level using multivariate linear regression. Thus, the SNP-1535 C>T of visfatin gene seemed to be potentially involved in the inflammatory component of TBI through a decreased production of visfatin.

Abstract
Experimental and prevalent case-control studies suggest an association between biomarkers of inflammation, endothelial function, and adiposity and cancer risk, but results from prospective studies have been limited. The authors' objective was to prospectively examine the relations between these biomarkers and cancer risk. A nested case-control study was designed within the Supplémentation en Vitamines et Minéraux Antioxydants (SU.VI.MAX) Study, a nationwide French cohort study, to include all first primary incident cancers diagnosed between 1994 and 2007 (n = 512). Cases were matched with randomly selected controls (n = 1,024) on sex, age (in 2-year strata), body mass index (weight (kg)/height (m)(2); <25 vs. ≥25), and SU.VI.MAX intervention group. Conditional logistic regression was used to study the associations between prediagnostic levels of high-sensitivity C-reactive protein (hs-CRP), adiponectin, leptin, soluble intercellular adhesion molecule 1 (sICAM-1), soluble vascular cell adhesion molecule 1, soluble E-selectin, and monocyte chemoattractant protein 1 and cancer risk. All statistical tests were 2-sided. Plasma sICAM-1 level was positively associated with breast cancer risk (for quartile 4 vs. quartile 1, multivariate odds ratio (OR) = 1.86, 95% confidence interval (CI): 1.06, 3.26; P(trend) = 0.048). Plasma hs-CRP level was positively associated with prostate cancer risk (for quartile 4 vs. quartile 1, multivariate OR = 3.04, 95% CI: 1.28, 7.23; P(trend) = 0.03). These results suggest that prediagnostic hs-CRP and sICAM-1 levels are associated with increased prostate and breast cancer risk, respectively.

Abstract
BACKGROUND The aim of this study is to evaluate the link between C-reactive protein (CRP) and Alzheimer's disease (AD) and mild cognitive impairment (MCI) among Mexican Americans. METHODS Non-fasting serum CRP levels, Mini-Mental State Examination scores, and Clinical Dementia Rating scale (CDR) scores were analyzed from 1,066 participants (Mexican American n = 471; non-Hispanic n = 595) of the Texas Alzheimer's Research & Care Consortium. RESULTS Among the total cohort, CRP levels among AD cases were significantly decreased as compared to normal controls (p < 0.001) and MCI cases (p = 0.002). CRP levels among MCI cases were decreased relative to controls (p = 0.03). Among Mexican American and non-Hispanic AD cases, CRP levels were significantly decreased among AD cases as compared to controls. CRP levels were only associated with disease severity (CDR scores) among non-Hispanics (p = 0.03) AD cases. CONCLUSIONS These results show that while CRP levels are decreased among Mexican American AD cases, CRP does not appear to be related to clinical variables as it is among non-Hispanic whites.

Abstract
BACKGROUND The effects of prenatal Zinc Deficiency (ZD) and Vitamin A Deficiency (VAD) on birthweight are controversial and their interaction has not been investigated. OBJECTIVE To assess the independent and interaction effects of prenatal zinc and vitamin A deficiencies on birthweight in rural Sidama, Southern Ethiopia. METHODOLOGY A community-based prospective cohort study design was employed. Six hundred fifty pregnant women in their second or third trimester were randomly selected and their serum zinc and retinol concentrations were determined. About 575 subjects were successfully followed until delivery and birthweight was measured within 72 hours after delivery. The association between the exposures and birthweight was examined using log-binomial and liner regression analyses. Potential interaction between ZD and VAD was examined using Synergy Index (SI). RESULTS The mean birthweight (± standard deviation) was 2896 g (±423). About 16.5% (95% CI: 13.5-19.6%) of the babies had Low Birthweight (LBW). Prenatal ZD and VAD were not significantly associated to LBW with Adjusted Relative Risk (ARR) of 1.25 (95 CI: 0.86-1.82) and 1.27 (95% CI: 0.86-1.87), respectively. Stratified analysis on the basis of gestational trimester showed that the occurrence of the deficiencies neither in the second nor third trimester were associated to LBW. The deficiencies did not show synergetic interaction in causing LBW [SI = 1.04 (95% CI: 0.17-6.28)]. Important risk factors of LBW were maternal illiteracy [RR = 1.80 (95% CI: 1.11-2.93)], female sex of the newborn [RR = 1.79 (95% CI: 1.19-2.67)], primiparity [RR = 1.16 (95% CI: 1.02-1.35)], short maternal stature [RR = 1.63 (95% CI: 1.06-2.51)] and maternal thinness [RR = 1.52 (95% CI: 1.03-2.25)]. In the linear regression model, elevated CRP was also negatively associated to birthweight. CONCLUSION LBW is of public health significance in the locality. The study did not witness any independent or interaction effect of prenatal ZD and VAD on birthweight.

Abstract
OBJECTIVE The aim is to characterize subgroups or phenotypes of rheumatoid arthritis (RA) patients using a systems biology approach. The discovery of subtypes of rheumatoid arthritis patients is an essential research area for the improvement of response to therapy and the development of personalized medicine strategies. METHODS In this study, 39 RA patients are phenotyped using clinical chemistry measurements, urine and plasma metabolomics analysis and symptom profiles. In addition, a Chinese medicine expert classified each RA patient as a Cold or Heat type according to Chinese medicine theory. Multivariate data analysis techniques are employed to detect and validate biochemical and symptom relationships with the classification. RESULTS The questionnaire items 'Red joints', 'Swollen joints', 'Warm joints' suggest differences in the level of inflammation between the groups although c-reactive protein (CRP) and rheumatoid factor (RHF) levels were equal. Multivariate analysis of the urine metabolomics data revealed that the levels of 11 acylcarnitines were lower in the Cold RA than in the Heat RA patients, suggesting differences in muscle breakdown. Additionally, higher dehydroepiandrosterone sulfate (DHEAS) levels in Heat patients compared to Cold patients were found suggesting that the Cold RA group has a more suppressed hypothalamic-pituitary-adrenal (HPA) axis function. CONCLUSION Significant and relevant biochemical differences are found between Cold and Heat RA patients. Differences in immune function, HPA axis involvement and muscle breakdown point towards opportunities to tailor disease management strategies to each of the subgroups RA patient.

Abstract
AIM It has been shown that pro-adrenomedullin is a good marker of the severity of septic shock but there are no data on the early changes in serum pro-adrenomedullin concentrations in patients with shock. METHODS Twenty-one patients with septic shock and 21 healthy subjects studied as controls. Serum concentrations of pro-adrenomedullin, procalcitonin, ferritin, CRP and IL-6 were determined in all subjects at the initial observation. Patients with septic shock were also studied after 24 and 48 hours. RESULTS The concentrations of the acute phase proteins were significantly higher in patients with septic shock than in the control subjects during the entire study period (P<0.001). Only procalcitonin significantly decreased on the third day of observation with respect to both the first day (P=0.002) and the second day (P=0.006). Proadrenomedullin (P=0.017) and IL-6 (P=0.001) showed an AUC significantly different from the null hypothesis in differentiating the patients who survived and those who did not. The sensitivity and specificity of pro-adrenomedullin in the assessment of death were 71.4% and 72.7%, respectively, while IL-6 had a sensitivity of 92.9% and a specificity of 60.6%. CONCLUSION Proadrenomedullin is a reliable prognostic marker in patients with shock; further studies on a more consistent number of septic patients will definitively assess whether proadrenomedullin may replace the current prognostic markers in critically ill patients with shock due to sepsis.

Abstract
BACKGROUND Magnesium is an essential ion for all living cells because over 300 enzymes require the presence of magnesium for their catalytic action. To date, no group has evaluated magnesium as a cardiovascular risk factor in chronic kidney disease (CKD) subjects, in which closely interrelated factors and potential confounders such as endothelial dysfunction, insulin resistance (the homeostasis model assessment (HOMA) index) and inflammation (expressed as serum C-reactive protein (CRP) levels) were also considered. METHODS Between March 2006 and December 2010, 283 CKD patients were followed up for time-to-event analysis until the occurrence of fatal or nonfatal cardiovascular events. Endothelium-dependent vasodilatation (flow-mediated dilatation; FMD) and endothelium-independent vasodilatation (nitroglycerin-mediated dilatation) of the brachial artery were assessed noninvasively using high-resolution ultrasound. RESULTS From the univariate analysis of FMD, it appears that a higher magnesium level is associated with less endothelial dysfunction. When a multivariate analysis was performed, magnesium and estimated glomerular filtration rates (eGFR) maintained a strong positive correlation with FMD, supporting the hypothesis that higher levels of magnesium may protect against endothelial damage. In univariate Cox proportional hazards models, FMD, magnesium, high sensitivity CRP, the HOMA index, eGFR, comorbid diabetes, hypertension, smoking status, systolic blood pressure, serum phosphate and intact parathormone emerged as significant predictors for cardiovascular outcomes. Kaplan-Meier curves showed significantly higher cardiovascular mortality rates in CKD patients whose serum magnesium levels were below 2.05 mg/dl. CONCLUSIONS This observational cohort study showed that magnesium may be an independent predictor of future cardiovascular outcomes and is the first study demonstrating such a role in etiologically diagnosed CKD patients, across different stages.

Abstract
Several lines of evidence have shown that plasma C-reactive protein (CRP) is associated with increased risk of stroke; however, previous studies were not adequately powered to assess whether plasma CRP levels are associated with stroke progression. In the current study, we designed a rabbit stroke model and investigated the relationship between plasma CRP and infarcted brain tissue. To produce a rabbit stroke model, we injected autologous thrombi into the left internal carotid artery. The plasma CRP levels were measured by ELISA at 0.5, 3, 6, 9, and 12 h poststroke. At 12 h, the rabbits were sacrificed, and the whole brains were examined by H & E and immunohistochemical staining with a monoclonal antibody against rabbit CRP. CRP mRNA expression in the infarcted tissue was evaluated by RT-PCR. Plasma CRP was markedly increased after embolic stroke. Plasma CRP positively correlated with the cerebral infarct area (r = 0.98, P < 0.01). Immunohistochemical staining revealed that CRP was frequently present in the infarcted area but not in normal cerebral tissue. RT-PCR showed that CRP was expressed in infarcted brain tissue. The plasma CRP level was significantly elevated after stroke and was closely correlated with the size of infarction, suggesting that CRP is an ideal marker to assess the acute embolic stroke.

Abstract
C-reactive protein (CRP), a plasma protein of the innate immune system, is produced by hepatocytes. A critical regulatory region (-42 to -57) on the CRP promoter contains binding site for the IL-6-activated transcription factor C/EBPβ. The IL-1β-activated transcription factor NF-κB binds to a κB site located nearby (-63 to -74). The κB site overlaps an octamer motif (-59 to -66) which is the binding site for the constitutively active transcription factor Oct-1. Oct-1 is known to function both as a transcriptional repressor and as an activator depending upon the promoter context. Also, Oct-1 can regulate gene expression either by binding directly to the promoter or by interacting with other transcription factors bound to the promoter. The aim of this study was to investigate the functions of Oct-1 in regulating CRP expression. In luciferase transactivation assays, overexpressed Oct-1 inhibited (IL-6+IL-1β)-induced CRP expression in Hep3B cells. Deletion of the Oct-1 site from the promoter drastically reduced the cytokine response because the κB site was altered as a consequence of deleting the Oct-1 site. Surprisingly, overexpressed Oct-1 inhibited the residual (IL-6+IL-1β)-induced CRP expression through the promoter lacking the Oct-1 site. Similarly, deletion of the Oct-1 site reduced the induction of CRP expression in response to overexpressed C/EBPβ, and overexpressed Oct-1 inhibited C/EBPβ-induced CRP expression through the promoter lacking the Oct-1 site. We conclude that Oct-1 acts as a transcriptional repressor of CRP expression and it does so by occupying its cognate site on the promoter and also via other transcription factors by an as yet undefined mechanism.

Abstract
BACKGROUND There are actually becoming controversial data regarding the profiles of interleukin-17 (IL-17) in different pathogenical stages of rheumatoid arthritis (RA). OBJECTIVES To assessing the IL-17 patterns in synovium, serum and synovial fluid from treatment-naïve early RA patients and to identifying potential correlations with disease activity markers and with synovial histopathological profile. MATERIALS AND METHODS Serum samples from 30 treatment-naïve early RA patients were evaluated for C-reactive protein (CRP), erythrocytes sedimentation rate (ESR), rheumatoid factor (RF), anti-cyclic citrullinated peptide antibodies (anti-CCP). IL-17A levels were also assessed in serum and synovial fluid (SF). Disease activity score (DAS28) calculation was done for all patients. Control serum and SF samples were obtained from 29 patients with osteoarthritis (OA); control synovium specimens were obtained from eight patients with OA and during surgery for knee tear ligaments. Histopathological (Hp) score, immunohistochemical reactivity for IL-17 were also assessed in synovium of early RA patients and controls. Dependencies between serum and synovial profile of IL-17A and the other parameters were statistically tested. RESULTS In early RA patients, strong correlations of serum and SF IL-17A levels were found with ESR, CRP, RF, anti-CCP, Hp score and IL-17 synovial immunoreactivity; a good correlation was noted with DAS28 score. Also, strong correlation was noted between serum and SF IL-17A levels. CONCLUSIONS In early stages of untreated RA, simultaneous IL-17 assessment of serum, SF and synovium might be valuable in defining activity and predictive patterns, given that synovium is highly suggestive for an disease aggressivity and might express specific therapeutically targets.

Abstract
PURPOSE To evaluate the role of interleukin-6 (IL-6) in the inflammatory and proliferative stages of Eales' disease (ED) and to determine the influence of IL-6-174G/C polymorphism in the IL-6 and IL-6-regulated protein expression, as well as the development of ED. METHODS One hundred and twenty-one patients diagnosed with ED, 223 matched healthy controls, and 16 control patients with macular holes were recruited from the eastern Indian population. Serum and vitreous levels of IL-6 and vascular endothelial growth factors (VEGF) were measured by enzyme-linked immunosorbent assay. Serum levels of high-sensitivity C-reactive protein (hsCRP) were measured by enzyme immunoassay. Subjects were genotyped for the IL-6-174G/C polymorphism (rs1800795) by a custom TaqMan single-nucleotide polymorphism (SNP) Genotyping Assays system. RESULTS Serum IL-6 (p<0.0001), hsCRP (p<0.0001), and VEGF (p=0.0031) levels were significantly higher in the inflammatory stage of ED than in healthy controls. Serum IL-6 also significantly correlated with hsCRP (Spearman's correlation coefficient; r=0.4992, p=0.0009), but not with VEGF in this stage in ED patients. At the proliferative stage of ED, significantly higher levels of vitreous IL-6 (p=<0.0001) and VEGF (p=<0.0001) were found compared with the vitreous of patients with macular holes. A significant correlation was observed between vitreous IL-6 and VEGF in ED patients (Spearman's correlation coefficient; r=0.5834, p=0.0087). A statistically significant association was found between the -174GG genotype (p=0.006) and occurrence of ED. Mean serum and vitreous concentrations of IL-6 were also higher in the subjects with the GG genotype than in those with the GC or CC genotype in this population. CONCLUSIONS IL-6 expression, regulated by the allelic distribution of -174 loci and the enhanced level of IL-6, modulates CRP and VEGF concentration depending respectively on the acute inflammatory stimulation at the initial stage and angiogenic stimulation at the advanced stage of ED.

Abstract
BACKGROUND The animal efficacy rule addressing development of drugs for selected disease categories has pointed out the need to develop alternative large animal models. Based on this rule, the pathophysiology of the disease in the animal model must be well characterized and must reflect that in humans. So far, manifestations of the acute radiation syndrome (ARS) have been extensively studied only in two large animal models, the non-human primate (NHP) and the canine. We are evaluating the suitability of the minipig as an additional large animal model for development of radiation countermeasures. We have previously shown that the Gottingen minipig manifests hematopoietic ARS phases and symptoms similar to those observed in canines, NHPs, and humans. PRINCIPAL FINDINGS We establish here the LD50/30 dose (radiation dose at which 50% of the animals succumb within 30 days), and show that at this dose the time of nadir and the duration of cytopenia resemble those observed for NHP and canines, and mimic closely the kinetics of blood cell depletion and recovery in human patients with reversible hematopoietic damage (H3 category, METREPOL approach). No signs of GI damage in terms of diarrhea or shortening of villi were observed at doses up to 1.9 Gy. Platelet counts at days 10 and 14, number of days to reach critical platelet values, duration of thrombocytopenia, neutrophil stress response at 3 hours and count at 14 days, and CRP-to-platelet ratio were correlated with survival. The ratios between neutrophils, lymphocytes and platelets were significantly correlated with exposure to irradiation at different time intervals. SIGNIFICANCE As a non-rodent animal model, the minipig offers a useful alternative to NHP and canines, with attractive features including ARS resembling human ARS, cost, and regulatory acceptability. Use of the minipig may allow accelerated development of radiation countermeasures.

Abstract
The purpose of this retrospective study was to develop a pre-treatment laboratory prognostic index (LPI) based on laboratory results that might serve as an extension to clinicopathological parameters for prognosis and treatment in patients with oral squamous cell carcinoma (OSCC). Pre-treatment LPI was calculated from C-reactive protein (CRP), hemoglobin (Hb) levels, and count of white blood cells (WBCs) due to significant (P < 0.05) association with locoregional recurrence measured for each parameter by receiver operating characteristic (ROC) curves in 187 patients with OSCC. Positive predictive values (+PV, precision rate) and negative predictive values (-PV) of LPI were measured. Likelihood ratios (LRs) were used to assess how good the pre-treatment LPI diagnostic test is to determine locoregional recurrence of the disease. CRP expression by cancer cells was confirmed by immunocytochemistry and FACS analysis. ROC analysis determined cutoff values for CRP levels, Hb levels, and WBC count and showed significant differences between nonrecurrent and recurrent group of OSCC. On univariate analysis, patients with high pre-treatment LPI (LPI ≥ 2, hazard ratio (HR) = 3.8670, 95% confidence interval (CI) = 2.2518-6.6407, P < 0.0001) had a significant poorer prognosis. Multivariate analysis showed that the most important independent prognostic factor was high pre-treatment LPI (LPI ≥ 2, HR = 3.6450, 95% CI = 2.3964-5.5441, P < 0.0001). Moreover, pre-treatment LPI ≥ 2 showed high probability that locoregional recurrence will be present later (+PV, LPI ≥ 2, 86.4%, 95% CI = 65.1-97.1). High +LR gave an excellent indication for a good quality of the test (LR+, LPI ≥ 2, 12.77, 95% CI = 8.8-18.6). Immunohistochemistry and FACS analysis confirmed inflammatory CRP expression by cancer cells. This study highlights the combination of inflammatory CRP levels, Hb levels, and WBC count as the most important independent prognostic factor in predicting disease recurrence of patients with OSCC. LPI can be used as a pre-treatment inflammatory biomarker that may identify OSCC with a more aggressive biological phenotype of the disease and might be helpful for guiding further post-operative treatment in OSCC.

Abstract
C-reactive protein (CRP), a marker for inflammation, was evaluated with other routine blood tests in children with newly diagnosed inflammatory bowel disease. Evaluation of CRP level helped identify additional patients found to have inflammatory bowel disease at endoscopy, although a sizeable number of patients with mild ulcerative colitis had a normal CRP level.
