Abstract
Functional foods that provide benefits beyond their traditional nutritional value have attracted much interest. Aim of the study was to evaluate the nutritional and the functional properties of a frozen ready-to-eat soup containing barley and pigmented vegetables. Both glycaemic index and the glyceamic load of ready-to-eat soup were evaluated in vivo. Moreover the bioavailability of carotenoids (lutein and beta-carotene) and the effect on lipid profile and lipid peroxidation were studied in 38 volunteers whose diet was supplemented for two weeks with a daily portion (250 g) of the ready-to-eat soup. Plasma levels of carotenoids (lutein and beta-carotene) and plasma total antioxidant capacity significantly increased after 2 weeks of treatment. Furthermore, we observed a decrease in the levels of lipids (total cholesterol and low density lipoprotein-cholesterol) and of markers of lipid peroxidation (oxidized low density lipoprotein and lipid hydroperoxides) in plasma of all subjects. The glyceamic index of the product was 36, therefore it could be considered a low glyceamic index food. An accurate selection of vegetable foods results in a palatable and healthy product that provides benefits on plasma lipids and lipid peroxidation (Protocol number 211525).

Abstract
In multiple injuries, features of bleeding from solid organs mostly involve the liver, spleen and kidneys and may be treated by embolization. The indications and techniques for embolization vary between organs and depend on the pathophysiology of the injuries, type of vascularization (anastomotic or terminal) and type of embolization (curative or preventative). Interventional radiologists should have a full understanding of these indications and techniques and management algorithms should be produced within each facility in order to define the respective place of the different treatment options.

Abstract
BACKGROUND AND AIM Oxidative stress is associated with insulin resistance pathogenesis, insulin secretion deficiency, and complication onset. Fermented papaya preparation (FPP), a dietary supplement obtained by fermentation of the papaya fruit, may be used as an antioxidant in the prevention of diabetic complications. METHODS AND RESULTS Platelets from 30 patients with type 2 diabetes mellitus (DM 2) and 15 healthy subjects were analyzed to evaluate the in vitro effects of FPP incubation. Na(+)/K(+)-adenosine triphosphatase (ATPase) activity, membrane fluidity, total antioxidant capacity (TAC), superoxide dismutase (SOD) activity, and conjugated diene levels were determined. In vitro FPP incubation improved platelet function, by enhancing Na(+)/K(+)-ATPase activity and membrane fluidity, and ameliorated the antioxidant system functionality, through an increase in TAC and SOD activity and a parallel decrease in conjugated diene levels in patients with DM 2. CONCLUSION Our data suggest that the incubation with FPP may have a protective effect on platelets from patients with DM 2, by preventing the progression of oxidative damage associated with diabetes and its complications.

Abstract
We analyzed predictive risk factors for recurrence of hepatocellular carcinoma (HCC) after orthotopic liver transplantation (OLT). We retrospectively analyzed the clinical data from 109 consecutive HCC patients who underwent OLT at our center from 1988 to 2007. We excluded all patients who died due to factors other than tumor recurrence within the first year (n = 24). The remaining 85 patients were enrolled in either a recurrence group (A; n = 19) or a nonrecurrence group (B; n = 66). Upon univariate analysis, the 2 groups were significantly different for 11 parameters. Group A included more females (P = .05), noncirrhotic liver recipients (P = .003), "up-to 7 status" patients (HCC with 7 as the sum of the size of the largest tumor [cm] and the number of tumors, P < .0001), patients exceeding Milan criteria (MC; P < .0001) or University of California San Francisco (UCSF) criteria (P < .0001), and OLT performed before 1999 (P = .003). Group A also showed a higher number of lesions (P = .035), a greater sum of diameters of the lesions (P < .0001), a major number of macrovascular (P < .0001) and microvascular invasions (P < .0001), and an increased number of G3-G4 grading (P = .006). Only microvascular invasion (P = .007) and exceeding UCSF criteria (P = .003) were independent risk factors for recurrence upon multivariate analysis. Patients with both these parameters are not candidates for OLT. Microvascular invasion is a good predictive parameter, but is impossible to detect preoperatively. New pre-OLT predictive risk factors are needed to achieve optimal results.

Abstract
Central nervous system (CNS) involvement in systemic lupus erythematosus (SLE) is reported in about 50% of patients. Among the neuropsychiatric features of SLE, myelopathy, including acute transverse myelitis (ATM) or acute longitudinal myelitis (ALM), represents an uncommon event. A possible vascular aetiology of SLE myelopathies has been hypothesized and it seems to be much more associated to SLE-associated antiphospholipid syndrome (APS). Furthermore, a possible infectious cause of ATM or ALM in healthy subjects has been described. SLE patients are susceptible to infection due to the disease itself or to the immunosuppressive therapy. Cryptococci non-neoformans have been rarely associated to infections in humans. Here we describe the case of a 47-year-old woman with SLE and Sjögren Syndrome who developed an ALM concurrently with a Cryptococcus laurentii pneumonia. The patient was treated with antimycotics, high doses of glucocorticoids and intravenous immunoglobulins with a significant clinical and radiological improvement. As far as we know, this is the first case of Cryptococcus laurentii infection and ALM in a patient with SLE who later developed a seronegative APS. Even though myelopathy may be considered primarily associated to SLE, a possible role of the infection in ALM development cannot be excluded.

Abstract
BACKGROUND Although fine needle aspiration (FNA) is the standard diagnostic test for the characterization of a suspicious thyroid nodule, in some cases cytological evaluation is inconclusive. The aim of this study was to determine the role of BRAF mutation in aiding diagnosis and to verify whether archival cytological samples could be suitable for molecular analysis. METHODS Eighty-five patients with suspicious (Thy4) or follicular (Thy3) lesions on cytology were resubmitted to a second FNA for BRAF mutation analysis. Of these, 56 subsequently underwent surgery. The usefulness of archival samples for molecular analysis was also studied in a second cohort of 42 patients with a confirmed diagnosis of papillary thyroid carcinoma for whom both archived paraffin-embedded histological samples and cytological smears were available. A further 15 patients with paired fresh FNA and archived cytological and histological samples were recruited. RESULTS BRAF mutation was found in the fresh FNA samples from 10 of 56 patients who had surgery with previous inconclusive cytology (4/45, 9%, Thy3 and 6/11, 55%, Thy4). The BRAF test showed a specificity and positive predictive value of 100% (26/26 and 10/10, respectively), sensitivity of 33% (10/30) and negative predictive value of 57% (26/46). There was absolute concordance between the BRAF results obtained with 42 histological and cytological archived samples. BRAF analysis on 15 archived cytological samples showed absolute concordance with histology, whereas there was one false negative on the matched fresh FNA. CONCLUSION BRAF analysis is a highly specific test that can facilitate cytological diagnosis in some cases and can also be performed on archived cytological samples.

Abstract
BACKGROUND Various biomarkers have been studied for diagnosing bacterial infections, seeking to stop the sepsis cascade. Presepsin, which is ∼13 kDa in size, has been identified to increase specifically in the blood of sepsis patients. Additionally, measurement of presepsin is useful to evaluate the severity of infection and monitor clinical responses. We evaluated the analytical and clinical performance of the Pathfast presepsin (PFP) assay system for early diagnosis of infection. MATERIALS AND METHODS From November 2011 to June 2012 we studied 70 adult patients, including 35 cadaveric organ transplant recipients and 35 abdominal surgery patients. The 32 female and 38 male subjects had a mean age of 56.1 years (range, 19-70). Heparinized whole blood for PFP assay was tested at 48 hours after surgery together with blood cultures. RESULTS The mean presepsin level (PL) in the 50 positive patients was 3,957.45 pg/mL (range 255-20,000). For transplant patients, PL was 3,034.43 ± 2,880.791 pg/mL, with 30 positive results. Microbiologic findings confirmed the presence of bacterial infections within 69 ± 2.5 hours from enrollment despite that when the test was performed, 70% showed no sign or symptom of infection. In 15 abdominal surgery patients, the PFP test was negative with negative blood cultures. The positive PFP test in 20 other abdominal surgery patients showed PL of 2,363 ± 7,988.47 pg/mL in the absence of signs or symptoms of infection in 25% of them. The 20 positive patients showed positive blood cultures within 67 ± 1.8 hours from enrollment. CONCLUSIONS The PFP test had a (100%) sensitivity to show the presence of infection in a short time (15 min), confirmed by positive blood cultures.

Abstract
In this review, we focus on current information on the apheresis procedures for endotoxins removal with Polymyxin B cartridges (PMX). This device has been designed in 2003 in Japan in order to take advantage of the antibiotic effects of Polymyxins on Gram negative bacteria and endotoxins, by-passing the toxicity shown by the intravenous administration. Although its mechanisms of action are nowadays well-known, we felt the need to sum up all the someway scattered information giving an overall sight on the entire process that brings Polymyxins molecules to function as powerful detergents of the endotoxins from the blood flow. Since the first experiences on humans, over one hundred studies have been published about the clinical use of this device. Even if some of them were limited in number of patients and compliance to international standards, they all converged in showing a highly positive impact of PMX on the improvement of clinic condition and outcome. Recently, more significant and large experiences confirmed the benefits of this treatment on hemodynamic, PaO2/FiO2 ratio, APACHE and SOFA scores and outcome at 28 days even on different typologies of sepsis cases, such as in transplanted patients. Summarizing, this relatively new procedure has proven to be a promising tool against Gram negative and endotoxin sepsis, combining clinical and outcome improvements with a fair cost/effectiveness ratio. Given that, there's still need of wider and more structured clinical studies that could steady the use of this device and widen its fields of applications.

Abstract
OBJECTIVE Methylglyoxal (MG), a reactive carbonyl compound formed primarily from triose phosphates, appears to be involved in the molecular mechanisms of diabetes, end-stage renal disease and neurodegenerative diseases. Methylglyoxal exerts several biological activities. Among these it promotes advanced glycation end products (AGEs), which are crucial in pathogenesis of human disease. Previous studies have demonstrated that MG reacts with proteins and compositional modifications reflect loss of biological activity. The aim of the study was to investigate the effect of in vitro MG-induced glycation on human high density lipoprotein (HDL) and on the activity of the enzyme paraoxonase-1 (PON1). METHODS HDL was incubated in the absence or in the presence of MG (0.2mmol/L and 1.0mmol/L) (MG-HDL) for different times (3, 6, 24h) at 37° C. We evaluated apoprotein compositional changes, in both control and MG treated HDL, using intrinsic fluorescence of tryptophan and monitoring the decrease of free amino groups. Furthermore we evaluated fluorescent advanced glycation end products (Ex=370nm, Em=440nm) and the activity of HDL-paraoxonase. RESULTS We demonstrated that human HDL is susceptible to glycation by MG (0.2mmol/L and 1mmol/L). The decrease of free amino groups and of intrinsic fluorescence of tryptophan demonstrates HDL apoprotein modifications in HDL incubated with MG. The compositional changes are associated with a significant increase in fluorescent advanced glycation end products and with a significant decrease of paraoxonase-1 enzyme activity associated with the HDL surface. CONCLUSIONS HDL-associated paraoxonase is responsible for the anti-inflammatory and anti-oxidative properties of HDL and detoxification against homocysteine-thiolactone. Therefore, modifications of apoprotein composition and the decrease of paraoxonase-1 activity in MG-treated HDL could affect the protective effect exerted by HDL against oxidative damage and could contribute to complications in patients affected by diseases associated with aging and oxidative stress.

Abstract
OBJECTIVE Obesity and/or psychopathological disorders of parents represent risk factors for childhood obesity. The aim of the study was to investigate the link between obesity in pregnancy and oxidative stress. METHODS Venous blood was collected from 37 women at the eighth month of gestation (19 obese and 28 normal weight). Cord blood was obtained at birth from newborns of obese mothers and controls. Cord blood and maternal blood was used to separate plasma to be used for the evaluation of leptin, oxidized LDL and paraoxonase (PON1) activity. RESULTS Higher levels of leptin were observed both in maternal blood and cord blood of children of obese women compared to normal-weight women. The data also showed lower levels of PON1 activity in plasma of obese women and in the cord blood of their children. Furthermore, a positive correlation was established between levels of PON1 activity in maternal blood and cord blood, suggesting a relationship between PON1 in maternal plasma and fetal cord blood. CONCLUSIONS Essential obesity in pregnancy is associated with hyperleptinemia. PON1 exerts an antioxidant role; therefore, our results demonstrated that obesity exposes to an increased susceptibility to oxidative damage in both mothers and newborns.

Abstract
BACKGROUND Psoriasis is a chronic, inflammatory skin condition associated with a high frequency of cardiovascular events. Modifications of plasma lipids, and an increase in the levels of biochemical markers of inflammation and lipid peroxidation have been reported in subjects with psoriasis, suggesting a relationship between psoriasis, inflammation and oxidative damage. OBJECTIVES To investigate whether modulation of inflammatory activity by tumour necrosis factor-α inhibitors in patients with psoriasis is associated with modification of lipid profiles, oxidative stress and paraoxonase (PON)1 activity. METHODS The levels of plasma lipids and lipoprotein(a), and the levels of the markers of inflammation and lipid peroxidation were evaluated in subjects with psoriasis (n=23) before and after 24 weeks of treatment with etanercept. In the same subjects plasma total antioxidant capacity and the activity of PON1, an antioxidant and anti-inflammatory enzyme associated with the high-density lipoproteins (HDLs), were investigated. RESULTS The results showed that clinical improvement in patients with psoriasis treated with etanercept is associated with a reduction in the levels of inflammatory markers [C-reactive protein (CRP)] and lipid peroxidation, and also with increased antioxidant capacity in the serum of patients with psoriasis. These modifications are associated with a significant increase in the activity of PON1. A significant increase in the PON1/CRP ratio has also been observed in patients with psoriasis after treatment. The significant inverse correlation between CRP and PON1 activity suggests a relationship between PON1 activity and inflammation. CONCLUSIONS Treatment with etanercept is associated with a reduction in lipid peroxidation and an improvement in HDL antioxidant and anti-inflammatory properties.

Abstract
Birth cohort studies of developmental defects of enamel (DDE) and early childhood caries (ECC) in very low birthweight (VLBW) and normal birthweight (NBW) infants are rare. In this birth cohort of 234 VLBW and 234 NBW infants, we report the incidence of ECC and DDE at 8 and 18-20 mos of corrected age. Infant medical and maternal socio-demographic data were abstracted from medical records at birth. Dental assessments for ECC and DDE (enamel hypoplasia, demarcated and diffuse opacities) were completed at 8 and 18-20 mos. The incidence of hypoplasia was significantly higher in VLBW compared with NBW infants (8 mos, 19% vs. 2%; 18 mos, 31% vs. 8%). The incidence of ECC (International Caries Detection and Assessment System: ICDAS ≥ 2) was 1.4% (8 mos) and 12% (18-20 mos) and was similar between the VLBW and NBW groups. At both ages, using a beta-binomial regression model to control for potential confounders (maternal and infant characteristics), we found increased risk for enamel hypoplasia among the VLBW infants compared with the NBW infants. African Americans had a lower risk for enamel hypoplasia at 18-20 mos. The VLBW infants should be monitored for ECC due to the presence of enamel hypoplasia.

Abstract
In this study we compared retrospectively the autopsy and the CT-scan findings in 47 gunshot victims (96 wounds) in order to assess the accuracy of the two methods in injury and ballistic diagnoses. Firing distance was determined in 46 wounds (47.9%). Firing range was determined by autopsy alone in 37 cases (80.5%) and by CT-scan alone in three cases (6.5%). In the six remaining cases (13%), autopsy and CT-scan reports concluded both to the same firing range. Entrance wounds were detected concordantly by both CT-scan and autopsy in 63 of the 91 penetrating wounds (69.2%). Exit wounds were present in 69 shots. They were concordantly detected by autopsy and CT-scan in 36 cases (52.2%). It was possible at CT imaging to determine the track of the bullet in up to 62 wounds (72.1%). CT-scan was superior to autopsy in determining two items: face fractures and pneumencephalon. CT scan was of limited value in demonstrating skull base fractures and contusions of the brain. There was good correspondence in demonstrating subarachnoid hemorrhage. CT-scan was accurate to demonstrate presence of gas, either in the pleural cavity (pneumothorax) or in the vessels' lumen (air embolism). Both autopsy and CT-scan were concordant in demonstrating thoracic well injuries, heart lacerations and intra thoracic hemorrhage. CT-scan was far below autopsy in detecting solid organs injuries except for kidneys. The present survey shows that CT-scan is second to none in demonstrating features as pneumencephalon, facial fractures, midline shifts, air embolism, pneumothorax, and pelvic bones fractures. It may contribute to determine the firing range in cases of contact-range and of intermediate range though the firing range assessment remains beyond post-mortem imaging possibilities, at least at the current state of knowledge.
