A Multifunctional Bread Rich in Beta Glucans and Low in Starch Improves Metabolic Control in Type 2 Diabetes: A Controlled Trial
Abstract: Design: Functional foods may be useful for people with diabetes. The soluble fibers beta
glucans can modify starch digestion and improve postprandial glucose response. We analyzed
the metabolic effects of a specifically designed \u2018functional\u2019 bread, low in starch, rich in fibers
(7 g/100 g), with a beta glucan/starch ratio of (7.6:100, g/g), in people with type 2 diabetes
mellitus. Methods: Clinical and metabolic data from two groups of age-, sex- and glycated
hemoglobin-matched diabetic subjects, taking either the functional bread or regular white bread,
over a roughly six-month observation period, were retrieved. Results: Bread intake did not change
during the trial. The functional bread reduced glycated hemoglobin by ~0.5% (absolute units) vs.
pre-treatment values (p = 0.028), and by ~0.6% vs. the control group (p = 0.027). Post-prandial and
mean plasma glucose was decreased in the treatment group too. Body weight, blood pressure and
plasma lipids did not change. The acceptance of the functional bread was good in the majority
of subjects, except for taste. Conclusions: A starch-restricted, fiber-rich functional bread, with an
increased beta glucan/starch ratio, improved long term metabolic control, and may be indicated in
the dietary treatment of type 2 diabetes
Essential amino acids: master regulators of nutrition and environmental footprint?
The environmental footprint of animal food production is considered several-fold greater than that
of crops cultivation. Therefore, the choice between animal and vegetarian diets may have a relevant
environmental impact. In such comparisons however, an often neglected issue is the nutritional value
of foods. Previous estimates of nutrients\u2019 environmental footprint had predominantly been based
on either food raw weight or caloric content, not in respect to human requirements. Essential amino
acids (EAAs) are key parameters in food quality assessment. We re-evaluated here the environmental
footprint (expressed both as land use for production and as Green House Gas Emission (GHGE), of
some animal and vegetal foods, titrated to provide EAAs amounts in respect to human requirements.
Production of high-quality animal proteins, in amounts sufficient to match the Recommended Daily
Allowances of all the EAAs, would require a land use and a GHGE approximately equal, greater o smaller
(by only \ub11-fold), than that necessary to produce vegetal proteins, except for soybeans, that exhibited
the smallest footprint. This new analysis downsizes the common concept of a large advantage, in
respect to environmental footprint, of crops vs. animal foods production, when human requirements of
EAAs are used for reference
The admission experience survey italian version (I-AES). a factor analytic study on a sample of 156 acute psychiatric in-patients
Coercive treatments are often regarded as an inevitable and yet highly debated feature of psychiatric care. Perceived coercion is often reported by patients involuntarily committed as well as their voluntary counterparts. The Admission Experience Survey (AES) is a reliable tool for measuring perceived coercion in mental hospital admission. We developed the Italian AES (I-AES) through translation back-translation and administered it to 156 acutely hospitalized patients (48% women, 69% voluntarily committed) in two university hospitals in Rome (Policlinico Umberto I, Sant'Andrea Hospital). A principal component analysis (PCA) with equamax rotation was conducted. The I-AES showed good internal consistency (Cronbach's alpha = 0.90); Guttmann split-half relia- bility coefficient was 0.90. AES total score significantly differed between voluntary and involuntary committed patients (5.08 ± 4.1 vs. 8.1 ± 4.9, p < .05). PCA disclosed a three-factor solution explaining 59.3 of the variance. Some discrepancies were found between the factor structure of the I-AES and the original version. I- AES total score was positively associated with numbers of previous involuntarily hospitalization (r = 0.20, p < .05) and psychiatric symptoms' severity (r = 0.22, p < .02). I-AES and its proposed new factor structure proved to be reliable to assess perceived coercion in mental hospital admission. Consequently, it may represent a helpful instrument for the study and reduction of patients' levels of perceived coercion
The contribution of muscle, kidney and splanchnic tissues to leucine transamination in humans
The first steps of leucine utilization are reversible deamination to \u3b1-ketoisocaproic acid (\u3b1-KIC) and irreversible oxidation. Recently the regulatory role of leucine deamination over oxidation was underlined in rodents. Our aim was to measure leucine deamination and reamination in the whole-body, in respect to previously determined rates across organs, in humans. By leucine and KIC isotope kinetics, we determined whole-body leucine deamination and reamination, and we compared these rates to those already reported across the sampled organs. As an in vivo counterpart of the "metabolon" concept, we analysed ratios between oxidation to either deamination or reamination. Leucine deamination to KIC was greater than KIC reamination to leucine in the whole-body (p=0.005), muscle (p=0.005) and the splanchnic area (p=0.025).These rates were not significantly different in the kidneys. Muscle accounted for 4860% and 4878%, the splanchnic bed for 4815% and 4815%, and the kidney for 4812% and 4818%, of whole-body leucine deamination and reamination rates, respectively. In the kidney, percent leucine oxidation over either deamination or reamination was >3-fold greater than muscle and the splanchnic bed. Skeletal muscle contributes by the largest fraction of leucine deamination, reamination and oxidation. However, in relative terms, the kidney plays a key role in leucine oxidation
Lumican is overexpressed in lung adenocarcinoma pleural effusions.
Adenocarcinoma (AdC) is the most common lung cancer subtype and is often associated with pleural effusion (PE). Its poor prognosis is attributable to diagnostic delay and lack of effective treatments and there is a pressing need in discovering new biomarkers for early diagnosis or targeted therapies. To date, little is known about lung AdC proteome. We investigated protein expression of lung AdC in PE using the isobaric Tags for Relative and Absolute Quantification (iTRAQ) approach to identify possible novel diagnostic/prognostic biomarkers. This provided the identification of 109 of lung AdC-related proteins. We further analyzed lumican, one of the overexpressed proteins, in 88 resected lung AdCs and in 23 malignant PE cell-blocks (13 lung AdCs and 10 non-lung cancers) using immunohistochemistry. In AdC surgical samples, lumican expression was low in cancer cells, whereas it was strong and diffuse in the stroma surrounding the tumor. However, lumican expression was not associated with tumor grade, stage, and vascular/pleural invasion. None of the lung cancer cell-blocks showed lumican immunoreaction, whereas those of all the other tumors were strongly positive. Finally, immunoblotting analysis showed lumican expression in both cell lysate and conditioned medium of a fibroblast culture but not in those of A549 lung cancer cell line. PE is a valid source of information for proteomic analysis without many of the restrictions of plasma. The high lumican levels characterizing AdC PEs are probably due to its release by the fibroblasts surrounding the tumor. Despite the role of lumican in lung AdC is still elusive, it could be of diagnostic value
Laser-assisted strategy for reflux abolition in a modified CHIVA approach
The aim of this study was to assess feasibility and efficacy of an endovenous laser (EL) assisted saphenous-sparing strategy in chronic venous disease (CVD). Fourteen CVD patients (C2,3,4s Ep As Pr1,2,3) underwent a saphenofemoral junction (SFJ) treatment by EL just from below the superficial epigastric vein downward for a limited tract, together with a flush ligation of the incompetent tributaries of the great saphenous vein (GSV) along the leg. The following GSV parameters were assessed 15 cm below the SFJ: reflux time, caliber, peak systolic velocity (PSV), end diastolic velocity (EDV), resistance index (RI). Venous clinical severity score and the Clinical, Etiological, Anatomical, and Pathophysio logical (CEAP) classification clinical classes were assessed. At 1 year follow up 3 cases were considered failures because of a GSV thrombosis, even if they presented a GSV recanalization with a laminar flow within at the 2 years follow-up. Eleven procedures succeeded because neither minor nor major peri-procedural complications were reported, apart 2 cases of self-healing bruising. In these last 11 cases the procedure led to a GSV reflux suppression (from 3.1±0.4 s to a retrograde laminar draining flow), to a GSV caliber reduction (from 9.4±0.5 to 3.1±0.2 cm, P<0.001), to a PSV reduction (from 50.2±4.6 to 18.4±3.5 cm/s, P<0.001), to a RI reduction (from 0.9±0.2 to 0.51±0.2, P<0.005) and to an oscillatory flow suppression (EDV from -8.9±1.6 to 6.2±2.3 cm/s, P<0.001). Both CEAP and venous clinical severity score improved from 3 to 1 (P<0.001) and from 7±2 to 2±1 (P<0.05), respectively. The GSV flow reappeared below the shrunk tract draining into the re-entry perforator. Sapheno-femoral reflux suppression can be obtained by just a GSV segmental closure. An almost 80% of success rate of the present investigation paves the way for an even wider diffusion of endovenous techniques, moreover erasing the surgical requirements for those who would like to perform a saphenoussparing strategy. In this way new devices could be used inside equally innovative strategies
Short endovenous laser ablation of the great saphenous vein in a modified CHIVA strategy
Mini-invasiveness, ease of use and execution speed represent the reasons for endovenous laser ablation success. Nevertheless, the strategic choice remains the ablation of the saphenous trunk. Hemodynamic correction (CHIVA) represents an option, based on a saphenous-sparing therapeutic strategy. We tested the feasibility of a modified CHIVA strategy by means of endovenous lasers (EL) shrinkage of segmental great saphenous vein (GSV) tracts, in networks characterized by sapheno-femoral incompetence and re-entry perforators focused on the GSV. We report the follow up of the first 2 chronic venous disease [C1,2,3sEpAsPr1,2,3, venous clinical severity score (VCSS) 8 and 9 respectively] treated cases. At 1-year follow up both patients were C1,2,3sEpAsPr1,2,3 and the VCSS were 1 and 2 respectively. The non-treated GSV tracts maintained their patency. ELs were herein used within a saphenous-sparing therapeutic plan, thanks to an accurate pre-operative hemodynamic assessment, which allowed the shrinkage of only the first saphenous trunk tract only. Proper technical and hemodynamic considerations are discussed
Ground motion areas detection (GMA-D): an innovative approach to identify ground deformation areas using the SAR-based displacement time series
Abstract. In this work, an innovative methodology to generate the
automatic ground motion areas mapping is presented. The methodology is based
on the analysis of the Synthetic Aperture Radar (SAR)-based displacement
time series. The procedure includes two modules developed using the
ModelBuilder tool (ArcGis). These modules allow to identify the ground
motion areas (GMA) using only one dataset and the persistent GMA (PGMA)
considering the different monitored periods and datasets. These areas
represent clusters of targets characterized by the same displacement time
series trend. The procedure was tested using different sensors such as
ERS-1/2, ENVISAT, COSMO-SkyMed and Sentinel-1 covering the periods,
1992–2000, 2003–2010, 2012–2016 and 2014–2017, respectively, over an area of
about 500 km2 in the Venetian-Friulian coastal Plain (NE Italy). The
resulting mapping allows to detect priority areas where to address further
in situ investigations such as to verify the presence of localized buried
landforms
Economic implications in inflammatory bowel disease: results from a retrospective analysis in an Italian Centre
BACKGROUND: Inflammatory bowel disease (IBD) represents a group of chronic conditions characterized by elevated costs. Over the last years, also a considerable healthcare burden associated with IBD has emerged, due to an increasing use of biological drugs and hospitalization costs. Despite the creation of local or regional databases, data regarding healthcare expenditure are lacking in Italy.AIM: To evaluate the treatment cost (biological drugs and hospitalizations) for patients with ulcerative colitis (UC) or Crohn’s disease (CD) treated with biological drugs.METHODS: Disease severity was evaluated by clinical scores (partial Mayo score and Harvey Bradshaw Index). We analyzed retrospectively patients treated with biologics referred to our IBD Unit between May 2015-April 2016 who underwent at least six months of follow-up (last visit October 2016). We calculated a mean cost per month of treatment for each patient. We also investigated the presence of any correlation between the monthly cost of treatment and demographic or clinical variables.RESULTS: We enrolled 142 patients (52 UC, mean age 44.3 years, male 40.4%; 90 CD, mean age 38.8 years, male 56.7%). About half of CD patients (48.9%) underwent previous intestinal surgery. The disease severity was higher in UC group vs CD group. In UC group infliximab was the most prescribed biologic (51.9%), followed by golimumab (26.9%) and adalimumab (21.2%). While CD patients were treated with adalimumab in 54.4% and infliximab in 45.6%. The mean monthly cost of treatment was € 1,235.41 ± 358.38 for UC and € 1,148.92 ± 337.36 for CD (p = 0.16). In both groups expenditure due to biologics amounts for more than 80%. We found a correlation between costs and disease activity (UC: p < 0.01; CD: p < 0.01).CONCLUSION: The main cost is due to biological drugs, but patients enrolled were the most severe in comparison to the whole IBD population under conventional therapy. As no cost differences were found between biologic drugs and the way of administration (intravenous or subcutaneous), the therapeutic choice should be driven by clinical reasons and not only economic ones
Elastic stockings effect on leg volume variability in healthy workers under prolonged gravitational gradient exposure
The aim of this study was to determine the elastic stockings effect on healthy workers (HW) who are exposed to a prolonged hydrostatic pressure overload for professional reasons. The cohort was composed by 20 HW who voluntarily underwent a water plethysmography test before and after eight hour of standing up in an operating room, wearing elastic stockings. After 8 h of gravity exposure, we demonstrated the absence of leg volume increase in case of elastic stockings use. In the morning measurement we found that the lower limb volume was 1967.5 mL±224, while in the evening it was 1962.5 mL±227 (P<0.0828). The decreased volume is significantly correlated with the time that was spent under gravity forces for working purpose wearing elastic stockings (R2=0.99, P<0.0001). Our experiment demonstrates that elastic stockings may effectively counteract the increased leg volume over time in workers who are exposed to prolonged gravitational gradient. Further longitudinal studies are needed to determine if the above effect could correct one of the major risk factors for the development of chronic venous insufficiency
