Abstract |
In city playgrounds, there is a potential risk of harming children's health by contamination coming from anthropogenic activities. With the aim to determinate the sources and the risk of hazardous elements, soil samples were collected in 19 selected playgrounds of different urban and rural areas from the Rio Grande do Sul state (Brazil). The concentration of 23 metals and metalloids and lead isotopic ratios were determined by ICP-MS. The methodology proposed here, firstly, classified the parks according to the average metal content by means of the NWACs (Normalized-and-Weighted Average Concentrations) and assess the contamination risk determining the Contamination Factors (CFs). Finally, statistical tools (correlation analysis and principal component analysis) were used to identify the most important contamination sources. The statistical tools used, together with lead isotopic composition analysis of the samples, revealed that coal combustion is the main source of contamination in the area. Vegetation was identified as a barrier for the contamination coming from the city. Nonetheless, some of the soils present a possible toxicological risk for humans. In fact, Cr, Sb, and Pb concentrations were higher than the Residential Intervention Values (VIRs) defined by the Environmental Protection Agency of the State of Sao Paulo, also in Brazil. |

Abstract |
For urban Brazil, the First World War triggered a dramatic food crisis that brought with it a massive increase in falsified goods and led to an uproar among the general public. Critics targeted the health authorities, who were evidently unable to suppress these frauds. This text spans the First Republic period and shows that since its proclamation the issue of regulating the food trade was part of health policies, but implementation was repeatedly delayed because of other priorities. This situation only changed with the health reforms of the early 1920s, which allows us to identify the First World War food crisis as a decisive point for the Brazilian state to take responsibility in this area. |

Abstract |
INTRODUCTION: Aberrant DNA methylation frequently occurs in the inflammatory mucosa in ulcerative colitis (UC) and is involved in UC-related tumorigenesis. We performed comprehensive DNA methylation profiling of the promoter regions of the inflamed rectal mucosae of patients with UC. DESIGN: The methylation status of the promoter CpG islands (CGIs) of 45 cancer/inflammation or age-related candidate genes and the LINE1 repetitive element were examined in the colonic mucosae of 84 cancer-free patients with UC by bisulfite pyrosequencing. Methylation status of selected genes (DPYS, N33, MIR1247, GSTP1, and SOX11) was also determined in 14 neoplastic lesions (5 with high-grade dysplasia and 9 with carcinoma) and 8 adjacent tissues derived from 12 patients. An Infinium HumanMethylation450 BeadChip array was used to characterize the methylation status of >450,000 CpG sites for 10 patients with UC. RESULTS: Clustering analysis based on the methylation status of the candidate genes clearly distinguished the inflammatory samples from the noninflammatory samples. The hypermethylation of the promoter CGIs strongly correlated with increased disease duration, which is a known risk factor for the development of colon cancer. Genome-wide methylation analyses revealed a high rate of hypermethylation in the severe phenotype of UC, particularly at the CGIs. Exclusively hypermethylated promoter CGIs in the severe phenotypes were significantly related to genes involved in biosynthetic processes, the regulation of metabolic processes, and nitrogen compound metabolic processes. CONCLUSION: Our findings suggest the potential utility of DNA methylation as a molecular marker and therapeutic target for UC-related tumorigenesis. |

Abstract |
BACKGROUND: Patients with inflammatory bowel disease (IBD) occasionally require central venous catheter (CVC) placement to support a therapeutic plan. Given that CVC can predispose patients to infection, this investigation was undertaken to assess the incidence, risk factors, and outcomes of CVC-related blood stream infection (CRBSI) in patients with IBD during routine clinical practice. METHODS: Data were compiled using retrospective chart reviews of 1367 patients treated at our IBD center between 2007 and 2012 during routine clinical practice. Among the 1367 patients, 314 who had received CVC placements were included. Patients with positive blood culture were considered as “definite” CRBSI, whereas “possible” CRBSI was defined as patients in whom fever alleviated within 48 hours post-CVC without any other infection. Patients' demographic variables including age, body mass index, serum albumin, duration of CVC placement, use of antibiotics, medications for IBD, and perioperative status between CRBSI and non-CRBSI subgroups were compared by applying a multivariate Poisson logistic regression model. RESULTS: Among the 314 patients with CVC placement, there were 83 CRBSI cases (26.4%). The average time to the onset of CRBSI was 22.5 days (range 4-105 days). The jugular vein access was found to be the most serious risk of CRBSI (risk ratio 2.041 versus subclavian vein). All patients with CRBSI fully recovered. CONCLUSIONS: In this investigation, regardless of the patients' demographic features including immunosuppressive therapy, up to 30% of febrile IBD patients with CVC showed CRBSI. It is believed that CVC placement per se is a risk of CRBSI in patients with IBD. |

Abstract |
We investigated the implications of hypervirulence determinants on clinical features of 48 adult patients with bacteremia caused by extended-spectrum beta-lactamase-producing Klebsiella pneumoniae. Isolates in the hypervirulence group included any of the following virulence determinants: K1/K2 capsule serotypes, hypermucoviscosity phenotype, rmpA gene, or rmpA2 gene. Nonhypervirulence group isolates were negative for all of the above virulence factors. In this study, all isolates used were non-K1/K2 strains. Statistically significant differences were observed in clinical features of patients between the two groups. The hypervirulent isolates (n = 19), including 11 isolates with the hypermucoviscosity phenotype, 15 with the rmpA gene, and 16 with the rmpA2 gene, were more commonly recovered from diabetic patients and mainly manifested as secondary bacteremia (such as pneumonia, urinary tract infections, or other localized infections). The nonhypervirulent isolates (n = 29) were more commonly recovered from patients after prolonged hospital stays (>30 days) and mostly manifested as primary bacteremia. The overall in-hospital mortality was 56.3%. Hazard ratio (HR) analysis revealed the following positive predictors for mortality: nosocomial infection, stay in an intensive care unit, no removal of the central venous catheter, Charlson comorbidity score, and APACHE II score (>==15). The negative predictors were initial appropriate antibiotic therapy (HR 0.42) and urinary tract infection (HR 0.19). Charlson score was an independent confounder based on multivariate analysis (HR 1.43, 95% confidence interval 1.04-1.99). In conclusion, hypervirulence determinants played a role in causing secondary infections in diabetic patients; however, the presence of morbidity cofactors could themselves influence mortality, despite the absence of hypervirulence determinants. |
