Abstract
As a crucial economic trait, fat deposition is directly related to carcass quality and feed efficiency in sheep. The purpose of this study was to investigate the polymorphisms of the FGB gene related to fat deposition and detect the expression features of the FGB gene in different adipose tissues of sheep by using Sanger sequencing, MassARRAY® SNP technique, and quantitative real-time PCR (qRT-PCR). Results showed that in the intron region of the FGB gene, a SNP g. 3378953 A > T has been identified, and significant association was found between perirenal fat weight, perirenal fat relative weight, mesenteric fat weight, and mesenteric fat relative weight (P < 0.05). Moreover, qRT-PCR analysis showed that FGB was expressed in all three adipose tissues, and FGB gene expression level in the AA genotype was significantly lower than that in the AT or TT genotypes (P < 0.05). Therefore, the FGB gene can be used as a candidate gene to reduce fat deposition in Hu sheep breeding, and the selection of the AA genotype in Hu sheep in production practice is more conducive to improving production efficiency.

J Surg Res 2023; 288:208-214. [PMID: 37023568 PMCID: PMC10192037 DOI: 10.1016/j.jss.2023.02.043] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 12/05/2022] [Accepted: 02/18/2023] [Indexed: 04/08/2023]
Abstract
INTRODUCTION Obesity is associated with higher mortality following trauma, although the pathogenesis is unclear. Both obesity and trauma are associated with syndecan-1 shedding and metalloproteinase-9 (MMP-9) activation, which can adversely affect endothelial cell function. We recently demonstrated that fibrinogen stabilizes endothelial cell surface syndecan-1 to reduce shedding and maintain endothelial barrier integrity. We thus hypothesized that MMP-9 activation and syndecan-1 shedding would be exacerbated by obesity after trauma but attenuated by fibrinogen-based resuscitation. MATERIALS AND METHODS ApoE null (-/-) mice were fed a Western diet to induce obesity. Mice were subjected to hemorrhage shock and laparotomy then resuscitated with Lactated Ranger's (LR) or LR containing fibrinogen and compared to null and lean sham wild type mice. Mean arterial pressure (MAP) was monitored. Bronchial alveolar lavage protein as an indicator of permeability and lung histopathologic injury were assessed. Syndecan-1 protein and active MMP-9 protein were measured. RESULTS MAP was similar between lean sham and ApoE-/- sham mice. However, following hemorrhage, ApoE-/- mice resuscitated with fibrinogen had significantly higher MAP than LR mice. Lung histopathologic injury and permeability were increased in LR compared to fibrinogen resuscitated animals. Compared with lean sham mice, both active MMP-9 and cleaved syndecan-1 level were significantly higher in ApoE-/- sham mice. Resuscitation with fibrinogen but not lactated Ringers largely reduced these changes. CONCLUSIONS Fibrinogen as a resuscitative adjunct in ApoE-/- mice after hemorrhage shock augmented MAP and reduced histopathologic injury and lung permeability, suggesting fibrinogen protects the endothelium by inhibiting MMP-9-mediated syndecan-1 cleavage in obese mice.

The effect of smoking on chronic inflammation, immune function and blood cell composition. Sci Rep 2020; 10:19480. [PMID: 33173057 PMCID: PMC7655856 DOI: 10.1038/s41598-020-76556-7] [Citation(s) in RCA: 79] [Impact Index Per Article: 19.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Accepted: 10/28/2020] [Indexed: 01/08/2023] Open
Abstract
Smoking is the number one risk factor for cancer mortality but only 15-20% of heavy smokers develop lung cancer. It would, therefore, be of great benefit to identify those at high risk early on so that preventative measures can be initiated. To investigate this, we evaluated the effects of smoking on inflammatory markers, innate and adaptive immune responses to bacterial and viral challenges and blood cell composition. We found that plasma samples from 30 heavy smokers (16 men and 14 women) had significantly higher CRP, fibrinogen, IL-6 and CEA levels than 36 non-smoking controls. Whole blood samples from smokers, incubated for 7 h at 37 °C in the absence of any exogenous stimuli, secreted significantly higher levels of IL-8 and a number of other cytokines/chemokines than non-smokers. When challenged for 7 h with E. coli, whole blood samples from smokers secreted significantly lower levels of many inflammatory cytokines/chemokines. However, when stimulated with HSV-1, significantly higher levels of both PGE2 and many cytokines/chemokines were secreted from smokers' blood samples than from controls. In terms of blood cell composition, red blood cells, hematocrits, hemoglobin levels, MCV, MCH, MCHC, Pct and RDW levels were all elevated in smokers, in keeping with their compromised lung capacity. As well, total leukocytes were significantly higher, driven by increases in granulocytes and monocytes. In addition, smokers had lower NK cells and higher Tregs than controls, suggesting that smoking may reduce the ability to kill nascent tumor cells. Importantly, there was substantial person-to person variation amongst smokers with some showing markedly different values from controls and others showing normal levels of many parameters measured, indicating the former may be at significantly higher risk of developing lung cancer.

Abstract
Total joint arthroplasty (TJA) of the hip or knee (THA, TKA) has become an increasingly common procedure. While TJA is a successful treatment for individuals experiencing degenerative joint diseases, it is well known that one of the most common perioperative complications of TJA is deep venous thrombosis (DVT). To profile tissue factor (TF), microparticle-tissue factor (MP-TF), thrombin-activatable fibrinolysis inhibitor (TAFI), and fibrinogen levels in patients undergoing TJA to determine potential preexisting Hemostatic dysregulation. De-identified blood samples were obtained from patients undergoing TJA 1 day pre- and 1 day postprocedure. Plasma samples were analyzed using enzyme-linked immunosorbent assay kits for fibrinogen, TAFI, TF, and MP-TF; fibrinogen levels were also assessed using a clot-based activity assay. In comparison with healthy controls, there were significant increases of fibrinogen and MP-TF levels, while there were significant decreases in TF and TAFI levels in the preoperative and postoperative patients. Comparing the pre versus postoperative patients, no significant differences were found; interestingly, however, surgical intervention exacerbated the changes found in the preoperative samples compared to the controls. The results of this study confirm that patients undergoing TJA have preexisting alterations in the fibrinolytic system. Surgical intervention tended to exacerbate these changes. The alterations observed in this study may provide insight as to why TJA is associated with higher rates of DVT and thromboembolism.

Abstract
Flavonoids in cocoa and yerba mate have a beneficial role on inflammation and oxidative disorders. Their effect on HIV individuals has not been studied yet, despite the high cardiovascular risk of this population. This study investigated the role of cocoa and yerba mate consumption on oxidative and inflammatory biomarkers in HIV+ individuals. A cross-over, placebo-controlled, double-blind, randomized clinical trial was conducted in 92 individuals on antiretroviral therapy for at least six months and at viral suppression. Participants were randomized to receive either 65 g of chocolate or chocolate-placebo or 3 g of yerba mate or mate-placebo for 15 days each, alternating by a washout period of 15 days. At baseline, and at the end of each intervention regimen, data regarding anthropometry, inflammatory, oxidative and immunological parameters were collected. High-sensitivity C-reactive protein, fibrinogen, lipid profile, white blood cell profile and thiobarbituric acid reactive substances were assessed. There was a difference between mean concentrations of HDL-c (ANOVA; p ≤ 0.05) among the different regimens: dark chocolate, chocolate-placebo, yerba mate and mate-placebo. When a paired Student t-test was used for comparisons between mean HDL-c at baseline and after each regimen, the mean concentration of HDL-c was higher after supplementation with dark chocolate (p = 0.008).

Abstract
BACKGROUND AND OBJECTIVE A number of studies have suggested inverse associations between lung function and inflammatory markers, including fibrinogen. In this study, we used data from the Newcastle Thousand Families birth cohort to assess the association between contemporaneous markers of lung function and fibrinogen while adjusting for potential confounding factors throughout life. METHODS At age 49-51 years, complete data on lung function and plasma fibrinogen were available for 380 study members. These data were analysed in relation to each other, adjusted for sex and height, with further adjustment for potential confounders within linear regression models using robust estimates. RESULTS Forced expiratory volume in 1 s was significantly inversely associated with plasma fibrinogen concentration after initial adjustments for sex and height (beta = -0.12, P = 0.011) and remained so after further adjustments for pack-years of cigarettes smoked and current smoking status. On further adjustment for standardized birthweight and duration breast-fed, the association approached statistical significance (P = 0.051). Adjusting for body mass index (BMI) resulted in a loss of significance (P = 0.09), but an unchanged regression coefficient, while, after adjustment for percent body fat, rather than BMI, the association was no longer significant (P = 0.20) and the coefficient reduced. CONCLUSIONS The association between lung function and fibrinogen remains after adjustment for potential early-life confounders and smoking. However, it is not independent of contemporaneous measures of adiposity, with evidence of confounding by percent body fat. Further studies, with measures of adiposity, are required to confirm whether associations between markers of inflammation and lung function are due to residual confounding by adiposity.

Abstract
OBJECTIVE Previous studies in acromegaly and growth hormone deficiency observed inverse associations between insulin-like growth factor-I (IGF-I) levels and inflammatory biomarkers including high-sensitive C-reactive protein (hsCRP), interleukin-6 or fibrinogen. We aimed to assess the relations between IGF-I or IGF binding protein 3 (IGFBP-3) levels and hsCRP, interleukin-6, fibrinogen and white blood cell count (WBC) in a population-based sample. DESIGN AND PATIENTS Data from 3480 subjects from the population-based Study of Health in Pomerania (SHIP) were used. IGF-I, IGFBP-3 and inflammatory biomarkers were measured. Analysis of variance (anova), quantile regression models and logistic regression models, adjusted for age, smoking, diabetes mellitus and waist circumference, were performed. MEASUREMENTS AND RESULTS anova and/or quantile regression showed inverse associations between IGF-I and hsCRP as well as positive associations between IGF-I and fibrinogen among both sexes. Furthermore, the odds of elevated fibrinogen levels increased with increasing IGF-I levels (per SD IGF-I increase: men: odds ratio (OR) 1·35 [95% confidence interval (CI) 1·04, 1·55]; women: OR 1·44 [95% CI 1·21, 1·71]) in both sexes, whereas the odds of increased hsCRP (women: OR 0·46 [95% CI 0·36, 0·58]) and interleukin-6 (men: odds ratio (OR) 0·77 [95% CI 0·61, 0·96]; women: OR 0·69 [95% CI 0·55, 0·86]) decreased. CONCLUSION Serum IGF-I levels are associated with inflammatory biomarkers including hsCRP, interleukin-6 and fibrinogen. Further experimental studies are needed to elucidate the mechanisms underlying the relation between the GH/IGF axis and the inflammatory system.

Abstract
BACKGROUND Metabolic disorders, in particular weight gain, increase cardiovascular mortality risk and can cause serious problems after renal transplantation. Weight and body mass index are imprecise indicators of nutritional status. Accurate determination of the body composition of renal transplant patients is essential; therefore, a simple tool that allows appropriate patient monitoring is crucial. DESIGN A new device, the Body Composition Monitor (BCM, Fresenius Medical Care, Bad Homburg, Germany), expresses body weight in terms of adipose tissue, lean tissue mass, and excess fluid. We compared the performance of this 3-compartment model with dual-energy X-ray absorptiometry (DEXA) as a reference method in determining body composition in a renal transplant population. SUBJECTS Thirty-three clinically stable renal transplant patients were studied. Bland-Altman plots and Passing-Bablok regression were used to compare methods. RESULTS Mean lean mass was 51.8 ± 12.3 kg with DEXA and 39.0 ± 9.9 kg with BCM. Despite the Passing-Bablok regression failing to find significant differences, the predictive value of BCM for DEXA was poor. Mean fat mass was 19.4 ± 9.7 kg with DEXA and 30.0 ± 16.0 kg with BCM. The slope of the regression line of BCM over DEXA significantly differed from 1. CONCLUSION We conclude that, in this population, these methods cannot be substituted for one another.

Abstract
BACKGROUND/OBJECTIVES Fiber-rich diets have been proposed to lower circulating levels of inflammatory makers. Our objective was to investigate cross-sectional relationships between fiber intake and plasma fibrinogen. SUBJECTS/METHODS We examined the relationship between plasma fibrinogen and dietary fiber in 20,960 men and women, aged 45-75 years old, living in Norfolk, U.K. Fiber intake was assessed using a food frequency questionnaire. RESULTS Mean fibrinogen levels were lower across the increasing quartiles of the fiber intake after adjusting for age, sex, body mass index, physical activity, smoking status and alcohol consumption, and total calories, percentage of energy intake from carbohydrate, protein and fat, with a difference of 0.08 g/l fibrinogen between first and fourth quartiles (P for trend <0.001) for the whole population. When categorized by sex, the results for men were the same and for women, the results failed to be significant. In linear regression models, fibrinogen levels were significantly related to fiber intake for the whole population (-0.056 g/l, s.e.=0.012 per 10 g increase in fiber intake, P<0.001), but although the relations were in the same direction after adjusting for the same covariates above, they failed to be significant when smokers or women not using post-menopause hormone therapy were separately considered. CONCLUSIONS Plasma fibrinogen levels appear to be inversely related to dietary fiber intake in middle-aged and older men and women.

Abstract
UNLABELLED The role of plasma fibrinogen levels in predicting metabolic syndrome (MetS) and assessment of determinants of these levels were investigated. A total of 2234 men and women, aged 49+/-12 years, representative of Turkish adults who had plasma fibrinogen determinations, were prospectively evaluated and followed for a mean of 6.6 years. The modified Clauss method was used for assays. MetS was defined by ATPIII criteria modified for male abdominal obesity. MetS cases at baseline were excluded in prospective analyses. Median (interquartile range) fibrinogen values were 2.87 (2.29; 3.56) g/L. Fibrinogen levels predicted significantly newly developing MetS in men (RR 1.40 [95%CI 1.07; 1.83] for a 2-fold increment), after adjustment for age and smoking status, and (RR 1.32 [95%CI 0.95; 1.83] again for doubling), after additional adjustment for all 5 components of MetS. MetS was not significantly predicted by fibrinogen levels in women in either multivariable model. By regression analysis of eight covariates, not waist circumference, but systolic blood pressure, current smoking and C-reactive protein (CRP) in men, and age in women were predictors of elevated (>3.0 g/L) fibrinogen at follow-up (p<0.05 in all). CONCLUSIONS Plasma fibrinogen predicts MetS independently of its components in men, in contradistinction to women, and, hence, is likely one of its components. Hyperfibrinogenemia representing an inflammatory state is postulated as the underlying mechanism. Central obesity is linked to elevation in fibrinogen mainly through the mediation of blood pressure, CRP, and via being affected by cigarette smoking.

Abstract
BACKGROUND HIV infection is associated with an increased risk of coronary artery disease, but the contribution of inflammation versus antiretroviral drugs is not well understood. Fibrinogen is an inflammatory factor associated with atherosclerosis. METHODS A total of 1131 HIV-infected patients and 281 controls [from the Coronary Artery Risk Development in Young Adults (CARDIA) study, a population-based study of cardiovascular risk assessment] in the Study of Fat Redistribution and Metabolic Change in HIV infection (FRAM) had plasma fibrinogen levels measured. Multivariable linear regression identified factors associated with fibrinogen. RESULTS HIV-infected patients had higher levels of fibrinogen compared with controls (males: 25 mg/dl higher, P = 0.006; females: 21 mg/dl higher, P = 0.39). Among HIV-infected persons, median levels of fibrinogen were 11% higher in patients currently using any protease inhibitor (PI) compared with those not using a PI (P < 0.0001). The strongest univariate associations were with the individual PIs, ritonavir and indinavir. Patients taking indinavir boosted with ritonavir had median fibrinogen levels 8% higher than those on indinavir alone (P = 0.049). Lower levels of fibrinogen were seen in those HIV-infected patients currently using any nonnucleoside reverse transcriptase inhibitor (NNRTI) compared to those not using an NNRTI (nevirapine -14.4%, P < 0.0001; efavirenz -7%, P = 0.0002). The associations of ritonavir, indinavir, efavirenz and nevirapine with fibrinogen levels persisted after multivariable analysis and were independent of other antiretroviral use. CONCLUSION Protease inhibitor use is associated with elevated fibrinogen levels which may contribute to increased risk of atherosclerosis in HIV-infected patients. Conversely, NNRTI use is associated with lower fibrinogen levels which may decrease risk of atherosclerosis.

Abstract
Hypertension is an important risk factor for cardiovascular diseases. There is increasing evidence suggesting that inflammation is involved in the development of hypertension. Interleukin-6 (IL-6) is an important mediator of inflammatory response and the major regulator of hepatic production of acute phase proteins, such as fibrinogen and C-reactive protein (CRP), which have been associated with hypertension and cardiovascular diseases. Therefore, we studied the association of single nucleotide polymorphism (SNP) in the IL-6 gene (IL6) promoter with plasma levels of fibrinogen, CRP and hypertension. Five hundred and two Hong Kong Chinese subjects (282 normotensives and 220 hypertensives) were recruited. IL-6 gene promoter was examined for polymorphism and the study subjects were genotyped for any SNP identified. The IL6 -572C>G polymorphism (rs1800796) was found with a frequency of 0.23 for the minor G allele. Subjects with the -572G allele had significantly higher plasma fibrinogen (3.06+/-0.57 vs 2.83+/-0.60, P=0.002) and CRP (interquartile range 0.33-1.56 vs 0.12-0.93, P=0.003) levels than those without. The -572C>G polymorphism was found to be an independent predictor of fibrinogen and CRP levels after adjusting for confounding factors. Plasma concentrations of fibrinogen and CRP correlated with systolic blood pressure. However, the -572C/G genotype frequencies did not differ between hypertensive and normotensive subjects, and there was no association between -572C>G polymorphism and blood pressure. Our results provide evidence that there is a clear genetic influence of IL6 -572C>G polymorphism on plasma levels of fibrinogen and CRP, but this polymorphism does not lead to elevated blood pressure.

Abstract
BACKGROUND Increased plasma levels of fibrinogen are been associated with an increased risk of cardiovascular accident. We aimed at verifying whether the changes of fibrinogen levels are associated with red blood cell (and/or hemoglobin) concentration. METHODS A group of 381 carefully selected healthy volunteers (219 male and 162 female), aged from 18 to 101 years, were enrolled in this study. Fasting blood samples were taken and all measurements (fibrinogen plasma level, whole blood viscosity, hemoglobin concentration, hematocrit value, red blood cell and white blood cell count, platelet count, glucose, total cholesterol and triglycerides plasma concentration, and C-reactive protein level) were obtained with standardized methodology using appropriate equipment, procedures, and controls. RESULTS AND CONCLUSIONS In the male but not in the female group, plasma fibrinogen concentration inversely correlated with hemoglobin (P < 0.0001) and hematocrit value (P < 0.01). In a post hoc analysis, plasma fibrinogen level inversely correlated with hemoglobin in the subgroup of the 93 premenopausal women and directly correlated with age and inversely correlated with platelet count in the subgroup of the 69 postmenopausal women. Results of multiple regression analysis revealed that in all the subjects, except in the postmenopausal women, hemoglobin level is an independent predictor of fibrinogen plasma level. Considering the physiopathologic role of increased plasma fibrinogen concentration and the scarcity of pharmacologic approaches to decrease its level, these findings could be important in designing a preventive therapy of cardiovascular disease.

Abstract
OBJECTIVE Hormone replacement therapy (HRT) has generally been documented to reduce plasminogen activator inhibitor-1 (PAI-1) and fibrinogen levels in plasma of postmenopausal women. We used a wash out protocol to study whether stopping long-term HRT with estrogen alone or a combination of estrogen-progestin have different effects on these markers of hemostasis. STUDY DESIGN Thirty healthy postmenopausal women on HRT participated. Fifteen had estradiol valerate, and 15 had estradiol valerate and levonorgestrel. Each was studied after long-term HRT (period 1), four weeks after cessation of the treatment (period 2, wash out), and three weeks after reintroducing the therapy (period 3). RESULTS In the estrogen group, PAI-1 increased by 18% during the wash out period (P=0.013) and decreased by 22% after reintroduction of therapy (P=0.001). In the combined therapy group, there was a trend of PAI-1 to increase by 18% when therapy was discontinued (P=0.17), and it decreased by 25% after reintroduction of hormone replacement therapy (P=0.036). Fibrinogen was initially lower in the estrogen group compared with the combined therapy group (p=0.014), and did not change during wash out. CONCLUSION This wash out study shows that cessation of long-term HRT unfavorably increases PAI-1, but appears to have no adverse effect on fibrinogen.

Abstract
PURPOSE AND METHOD Several studies have suggested that physical inactivity and obesity increase the risk for colorectal neoplasia. In this study, we investigated the association of physical activity and body mass index (BMI) with the risk of different types of large bowel polyps. We did an observational analysis nested within a randomized double-blind placebo-controlled chemoprevention trial among patients with one or more recently resected histologically confirmed colorectal adenoma. Nine hundred thirty patients were randomized to calcium (1,200 mg/d, as carbonate) or placebo. Follow-up colonoscopies were conducted approximately 1 and 4 years after the qualifying examination. At study entry, we obtained each subject's current body weight and height, which we used to calculate BMI. After the second study colonoscopy, we asked subjects questions about their leisure time physical activity. Seven hundred eighty-seven subjects completed at least part of the physical activity questionnaire. RESULTS We found no association between measures of physical activity or BMI and tubular adenomas or hyperplastic polyps. However, among men, there were strong inverse associations observed between physical activity and advanced neoplastic polyps. Compared with men whose total daily energy expenditure was in the lowest tertile, those in the highest tertile had a risk ratio of 0.35 (95% confidence interval, 17-0.72); there was no similar reduction observed among women (risk ratio, 1.21; 95% confidence interval, 0.36-4.03; P for interaction = 0.04). DATA INTERPRETATIONS We found a significant inverse relationship between several measures of physical activity and risk of advanced colorectal neoplasms, particularly among men. No associations were found between BMI and hyperplastic polyps, tubular adenomas, or advanced neoplastic polyps.
