Abstract
BACKGROUND Rising global obesity rates are linked with inflammation and associated morbidities. These negative outcomes are generally more common in low-resource communities within high-income countries; however, it is unclear how frequent infectious disease exposures in these settings may influence the relationship between adiposity and inflammation. AIM We test associations between adiposity measures and distinct forms of inflammation among adults (n = 80) living in low-resource U.S. communities experiencing high levels of obesity and pathogen exposure. SUBJECTS AND METHODS Adiposity measures included BMI and percent body fat. Inflammation measures included systemic inflammation (C-reactive protein [CRP]) and localised intestinal inflammation (faecal calprotectin [FC]). The relationship between a condition characterised by elevated inflammation (Helicobacter pylori infection) and adiposity was also considered. RESULTS Adiposity was not significantly related to FC concentration. However, both adiposity measures were positively related with odds of CRP elevation and H. pylori infection was associated with significantly lower adiposity measures (all p < 0.05). CONCLUSION For this disadvantaged U.S. sample, the association between adiposity and inflammation varies by the systemic/localised nature of inflammation and the likely underlying cause of inflammation. Defining these associations will improve understanding of how rising obesity rates shape long-term health inequities, with implications for more effective intervention design.

Abstract
BACKGROUND Childhood obesity is most prevalent nutritional disorder worldwide. Studies on clinical correlations between body fat (BF) composition, lipid profile, inflammatory biomarkers, and endothelial dysfunction (ED) parameters in children from United Arab Emirates (UAE) are limited. Therefore, we aimed to study obesity pattern in children and determine clinical correlations with biomarkers. METHODS Children (6-13 years) from different schools were divided into obese, overweight, and normal groups based upon Centers for Disease Control and Prevention weight-for-age centiles study (n=166). Anthropometric, BF composition, lipid profile, inflammatory, and ED biomarkers were determined and analyzed using SPSS software. RESULTS The mean age and weight ± SD of participants were 10.6 ± 2.6 years and 48.2 ± 19.5 kg with 65% as overweight or obese. In normal, overweight, and obese group male were 40 (70.2%), 35 (67.3%), and 40 (70.2%) and female were 17 (29.8%), 17 (32.7%) and 17 (29.8%). There was significant difference in age (p<0.01), height (p< 0.01), weight (p< 0.01) among groups. Obesity markers (MCP-1, leptin, adiponectin) showed positive correlation with age, height, weight, WC, BF%, body fat mass (BFM), body muscle mass (BMM). A significant correlation (all p<0.01) of BMM with SBP (r=0.412), DBP (r=0.255), MCP-1 (r=0.558), adiponectin (r=0.635), hs-CRP (r=0.263), IL-6 (r=0.348), TNF-alpha (r=0.370), ICAM-1 (r=0.237), and VCAM-1 (r=0.343). The inflammatory markers (ICAM-1, VCAM-1) showed significant correlations with age, height, weight, WC, BF%, BFM, BMM. Leptin significantly (all p<0.01) correlated with age (r=0.470), height (r=0.423), weight (r=0.677), WC (r=0.606), BF (r=0.700), BFM (r=0.752), and BMM (r=0.524) and negatively correlated with TBW (r=-0.701). Adiponectin also showed a significant (all p<0.01) positive correlation with age, height, weight, WC, BF, BFM, and BMM. CONCLUSION A strong association between BF composition, lipid profile, and inflammatory and ED biomarkers was observed in the study. Thus, immediate measures should be implemented to reduce risk of obesity and associated diseases.

Abstract
BACKGROUND The impact of the changes in the obesity status on mortality has not been established; thus, we investigated the long-term influence of body fat (BF) changes on all-cause deaths and cardiovascular outcomes in a general population. METHODS A total of 8374 participants were observed for 12 years. BF was measured at least two times using a bioimpedance method. The causes of death were acquired from the nationwide database. A major adverse cardiovascular event (MACE) was defined as a composite of myocardial infarction, coronary artery disease, stroke, and cardiovascular death. Standard deviations (SDs) were derived using a local regression model corresponding to the time elapsed between the initial and final BF measurements (SDT) and were used to standardize the changes in BF (ΔBF/SDT). RESULTS The incidence rates of all-cause death, cardiovascular death, and MACE were the highest in the participants with ΔBF/SDT <-1 and lowest in the participants with ΔBF/SDT ≥1. Multivariate Cox proportional hazard models adjusted for relevant covariates, including baseline obesity and physical activity, showed that the risks of all-cause deaths (hazard ratio [HR] 0.58; 95% confidence intervals [CI] 0.53-0.64), cardiovascular deaths (HR 0.63; 95% CI 0.51-0.78) and MACEs (HR 0.68; 95% CI 0.62-0.75) decreased as ΔBF/SDT increased. Subgroup analyses showed that existing cardiovascular diseases weakened the associations between higher ΔBF/SDT and better outcomes, while high physical activity and exercise did not impact the associations. CONCLUSION Increasing BF was associated with a lower risk of all-cause death, cardiovascular death, and MACE in the general population.Key messagesIncreasing body fat is associated with a lower risk of all-cause death, cardiovascular death, and major cardiovascular adverse events in a low-risk ageing general population, independently of physical activity, underlying cardiovascular disease burden, changes in muscle mass, and baseline obesity status.Fatness measured at baseline requires adjustment for the changes in fatness during the follow-up to reveal its impact on the clinical outcomes.

Abstract
OBJECTIVES Peruvians are experiencing rapid dietary and lifestyle changes, resulting in a phenomenon known as the "dual burden of disease." A common manifestation of the dual burden in individuals is the co-occurrence of overweight and anemia. Despite recent initiatives introduced to address these concerns, rates continue to be public health concerns. This study investigates the relationship between immune activation and lack of response to iron supplementation after 1 month of treatment and explores variation in body fat stores as a potential moderator between immune function and response to treatment. METHODS Data come from children, aged 2-5 years (n = 50) from a peri-urban community in Lima, Peru. Multivariate logistic regression models were used to explore the associations between response to treatment (Hb > =11.0 g/dl) after 1 month of treatment), markers of immune activation (C-reactive protein [CRP] and reported morbidity symptoms), and measures of body fat (waist-to-height ratio, triceps skinfold thickness, and body mass index [BMI]). RESULTS We found that high CRP is associated with a lack of response to iron supplementation after 1 month of treatment and that BMI z-score may moderate this association. Generally, larger body size is associated with response to iron supplementation whether or not the children in this sample have high immune activation. However, the probability of anemic children responding to iron supplementation treatment differed across adiposity measures. CONCLUSIONS Our finding suggesting that adiposity and CRP influence response to iron supplementation, furthers our understanding of the relationship between inflammation and anemia treatment in children and has both theoretical and public health implications.

Abstract
Conflicting results have been reported regarding human herpes virus (HHV) reactivation in patients with rheumatoid arthritis (RA). To explore this link, 74 RA patients were selected and compared to 42 first degree relatives (FDR) from probands with RA and 25 healthy controls from the Tatarstan women cohort. The serological analysis was done by testing anti-HSV/CMV/EBV IgM, IgG, plus the IgG avidity index, and completed by evaluating HSV/CMV/EBV DNA by PCR. Results from these analyses reveal: (i) a long lasting infection of HHV in RA, FDR and healthy controls (IgG seroconversion >97%); (ii) an elevated IgM anti-HHV response in seroconverted RA patients which is related to HSV1/2 reactivation (HSV1/2 PCR+); and (iii) a multi-reactive IgM HHV burden profile associated with disease activity (DAS28). In conclusion, HSV1/2 reactivation in seroconverted RA patients is associated with an abnormal anti-HHV immune response, which was reflected in IgM HHV burden, and in activity disease profile.

Abstract
PURPOSE OF REVIEW Obesity is a multifactorial disease that is now endemic throughout most of the world. Although addressing proximate causes of obesity (excess energy intake and reduced energy expenditure) have been longstanding global health priorities, the problem has continued to worsen at the global level. RECENT FINDINGS Numerous microbial agents cause obesity in various experimental models-a phenomena known as infectobesity. Several of the same agents alter metabolic function in human cells and are associated with human obesity or metabolic dysfunction in humans. We address the evidence for a role in the genesis of obesity for viral agents in five broad categories: adenoviridae, herpesviridae, phages, transmissible spongiform encephalopathies (slow virus), and other encephalitides and hepatitides. Despite the importance of this topic area, there are many persistent knowledge gaps that need to be resolved. We discuss factors motivating further research and recommend that future infectobesity investigation should be more comprehensive, leveraged, interventional, and patient-centered.

Abstract
BACKGROUND Gastritis is an important premalignant lesion and recent studies suggested a production of inflammatory cytokine-like C-reactive protein during gastritis. This study aimed to determine any relationship between high sensitive C-reactive protein (hs-CRP) and inflammation activity among patients with gastritis. METHODS Demographic and clinical variables of participants were collected by a validated questionnaire. Using histology of the gastric mucosa, Helicobacter pylori status was investigated and serum concentrations of hs-CRP were measured among dyspeptic patients. Correlation between hs-CRP serum levels and inflammation activities was evaluated by logistic regression analysis. The relation between active inflammation and other variables was evaluated by logic link function model. RESULTS Totally 239 patients (56.6% female) were analysed. The prevalence of mild, moderate and severe inflammation activities was 66.5%, 23.8% and 9.6% respectively. Mean ± SD of hs-CRP among men and women were 2.85 ± 2.84 mg/dl and 2.80 ± 4.80 mg/dl (p = 0.047) respectively. Mean ± SD of hs-CRP among patients with H. pylori infection, gland atrophy, metaplasia and dysplasia were 2.83 ± 3.80 mg/dl, 3.52 ± 5.1 mg/dl, 2.22 ± 2.3 mg/dl and 5.3 ± 5.04 mg/dl respectively. Relationship between hs-CRP and inflammation activities (p < 0.01) was significant. A significant relationship between dysplasia and hs-CRP (p < 0.04) was revealed. A significant relationship between age and hs-CRP was detected (p < 0.05). CONCLUSION Although serum hs-CRP is not a specific biomarker for gastritis, elevated hs-CRP levels may be considered as a predictive marker of changes in gastric mucosa and a promising therapeutic target for patients with gastritis.

Abstract
Elevated skeletal muscle expression of toll-like receptor 4 (TLR4) has been linked to increased inflammation in clinical populations. TNFα converting enzyme (TACE), which cleaves membrane-bound TNFα (mTNFα) to its soluble (sTNFα) and more bioactive form, has been linked to chronic disease. In contrast, higher physical activity level is associated with decreased chronic disease risk and inflammation. The purpose of the present study was to examine the relationship between physical activity and skeletal muscle TLR4, TACE, and TNFα in older adults. In 26 older adults (age = 68 ± 4 years, body mass index = 26 ± 3 kg·m(-2)), self-reported physical activity (kcal·week(-1)), estimated maximal oxygen consumption, and body composition (air plethysmography) were measured. TLR4, TACE, mTNFα, and sTNFα were measured in skeletal muscle biopsies (vastus lateralis) using western blot analyses. Pearson product-moment correlations were run between variables. Significance was set at p < 0.05. Skeletal muscle TACE was directly associated with sTNFα (r = 0.53, p < 0.01). Linear regression modeling showed that mTNFα and TACE expression were predictive of sTNFα expression. No correlations were observed between physical activity and TLR4, TACE, or sTNFα. Percent body fat was directly associated with skeletal muscle TLR4 (r = 0.52, p < 0.01) and TACE (r = 0.50, p < 0.01), whereas fasting blood glucose was directly associated with TACE and sTNFα. In conclusion, we found that percent body fat was directly associated with TLR4 and TACE expression in skeletal muscle of older adults. These findings suggest that elevated skeletal muscle expression of TLR4 and TACE may contribute to the augmented inflammation and chronic disease risk observed with increased adiposity.

Abstract
BACKGROUND The environmental and behavioral risk factors associated with central obesity and/or inflammation in populations exposed to both obesogenic and pathogenic environments remain unclear. OBJECTIVES We tested which of the characteristics distinguished 3 risk groups--high waist-to-height ratio (WHtR; >0.5) without inflammation [high-sensitivity C-reactive protein (hs-CRP) <3 mg/L], normal WHtR (≤ 0.5) with inflammation (hs-CRP: 3-10 mg/L), and high WHtR with inflammation--from the referent group with normal WHtR without inflammation and, secondarily, which factors differed between the groups with high WHtR with and without inflammation. METHODS The analytic sample included 8068 adults participating in the China Health and Nutrition Survey in 2009. Adjusted multinomial and logistic regression models were used to assess the risk of being in one of the "unhealthy" groups compared with the referent group. RESULTS Men with high WHtR with and without inflammation were more likely to live at higher urbanicity (57-63%) and have higher incomes (26-42%) and household sanitation (26-67%) and were >40% less likely to have high physical activity than the healthy referent group. Men with high WHtR with inflammation had higher odds of infectious symptoms than those with high WHtR without inflammation (OR: 1.73; 95% CI: 1.15, 2.61). Women with high WHtR without inflammation were less likely to have high household sanitation (44%) or perform high levels of physical activity (24%) and were 34% more likely to consume more fiber than the healthy referent group. Women with high WHtR and inflammation were more likely than those with high WHtR without inflammation to have infectious symptoms (OR: 1.45; 95% CI: 1.01, 2.07) and less likely to have higher fiber intake (OR: 0.77; 95% CI: 0.60,1.00) or physical activity (OR: 0.55; 95% CI: 0.41, 0.73). CONCLUSION These results document different underlying pathogenic and obesogenic risk factors for visceral adiposity with and without inflammation in Chinese adults, suggesting that context-specific approaches may be needed to prevent and treat inflammation.

Abstract
Helicobacter pylori infection may contribute to the development of extra-gastroduodenal diseases. The aim of this study was to explore whether this infection could influence metabolic parameters and body composition of dyslipidemic patients. In an 8-month period, 155 patients attended our clinic; 110 patients (48 men and 62 women, age 35-55 years) fulfilled inclusion criteria. Metabolic parameters were determined by routine tests and body composition by anthropometry and bioelectrical impedance analysis. The H. pylori and CagA infectious status were examined serologically. Sixty-one patients (55.4%) had serum antibodies to H. pylori and 30 infected patients (49.1%) had anti-CagA antibodies. The mean percentage of fat mass and level of high-density protein cholesterol in seropositive patients were significantly lower than those measured in seronegative ones (P = 0.008 and P < 0.001, respectively). The mean glucose concentration in patients with anti-H. pylori serum IgG was significantly higher than in uninfected patients (P = 0.021). No significant difference was observed regarding the other parameters. The CagA status did not influence any of the considered parameters. Our results are in agreement with those of other studies; however, the level of concordance of results reported in the various publications on this topic is very low, presumably from differences concerning the age, alimentary habits and possible presence of different pathologies in the groups studied. The most plausible hypothesis for the observed alterations may exist in the low-grade systemic inflammatory status of infected individuals, which may influence the fat turnover and support the insulin resistance with consequent alteration of glucose metabolism.

Abstract
OBJECTIVES Influenced by pathogen exposure and obesity, inflammation provides a critical biological pathway linking changing environments to the development of cardiometabolic disease. This study tests the relative contribution of obesogenic and pathogenic factors to moderate and acute CRP elevations in Chinese children, adolescents and adults. METHODS Data come from 8795 participants in the China Health and Nutrition Study. Age-stratified multinomial logistic models were used to test the association between illness history, pathogenic exposures, adiposity, health behaviors and moderate (1-10 mg/L in children and 3-10 mg/L in adults) and acute (>10mg/L) CRP elevations, controlling for age, sex and clustering by household. Backward model selection was used to assess which pathogenic and obesogenic predictors remained independently associated with moderate and acute CRP levels when accounting for simultaneous exposures. RESULTS Overweight was the only significant independent risk factor for moderate inflammation in children (RRR 2.10, 95%CI 1.13-3.89). History of infectious (RRR 1.28, 95%CI 1.08-1.52) and non-communicable (RRR 1.37, 95%CI 1.12-1.69) disease, overweight (RRR 1.66, 95%CI 1.45-1.89) and high waist circumference (RRR 1.63, 95%CI 1.42-1.87) were independently associated with a greater likelihood of moderate inflammation in adults while history of infectious disease (RRR 1.87, 95%CI 1.35-2.56) and overweight (RRR 1.40, 95%CI 1.04-1.88) were independently associated with acute inflammation. Environmental pathogenicity was associated with a reduced likelihood of moderate inflammation, but a greater likelihood of acute inflammation in adults. CONCLUSIONS These results highlight the importance of both obesogenic and pathogenic factors in shaping inflammation risk in societies undergoing nutritional and epidemiological transitions.

Abstract
BACKGROUND Chronic infection with cytomegalovirus (CMV), Chlamydia pneumoniae, herpes simplex virus 1 (HSV-1), and Helicobacter pylori may contribute to essential hypertension. However, the evidence now available does not clarify whether the aggregate number of pathogens (pathogen burden) may be associated with hypertension. METHODS Sera from 1,754 men and women aged ≥25 years were analyzed for immunoglobulin G antibodies to C. pneumoniae, HSV-1, H. pylori, and CMV using enzyme-linked immunosorbent assay. The aggregate number of seropositives to the studied viral and bacterial agents was defined as pathogen burden. Hypertension was defined according to World Health Organization criteria. RESULTS A total of 459 (26.3%) of the subjects had hypertension. In the hypertensive group, 4.2% had 0 or 1 pathogens present, 20.6% had 2, 43.2% had 3, and 32.1% had 4; in the normotensive group, 7.9% had 0 or 1, 28.4% had 2, 42.7% had 3, and 21.0% had 4. Of the 4 studied pathogens, H. pylori seropositivity showed a significant independent association with hypertension (odds ratio (OR) =1.37; 95% confidence interval (CI) =1.05-1.79; P = 0.02). In multiple logistic regression analyses, the pathogen burden did not show a significant independent association with hypertension. Coinfection with H. pylori and C. pneumoniae was significantly associated with hypertension compared with double seronegativity after adjustment for age, sex, chronic low-grade inflammation, and cardiovascular risk factors (OR = 1.68; 95% CI = 1.14-2.47; P = 0.008]. CONCLUSIONS The pathogen burden was not associated with hypertension. However, coinfection with C. pneumoniae and H. pylori showed a significant association with essential hypertension, independent of cardiovascular risk factors and chronic low-grade inflammation.
