Insulin Resistance and Hyperinsulinemia in Patients with Chronic Liver Disease and Hepatocellular Carcinoma
ObjectivesTo investigate the role of insulin resistance (IR) and insulin plasma levels (IRI) in patients with chronic liver disease (CLD) and hepatocellular carcinoma (HCC).MethodsWe recruited the following patients: 125 with HCC, 128 with liver cirrhosis (LC) and 133 with chronic hepatitis C (CHC). IR was assessed by the HOMA-IR method. To define IR and hyperinsulinemia we selected as a cut-off level, the value of the 80th percentile for HOMA-IR (2.72) and IRI (11.18) in 113 healthy subjects.ResultsThe mean levels of HOMA-IR and IRI increase progressively among CHC (2.7 ± 2.9 and 11.5 ± 10.5, respectively), LC (5.4 ± 4.5 and 17.6 ± 11.2) and HCC (6.4 ± 9.8 and 18.2 ± 18.8). In the upper quintiles for HOMA-IR and IRI, the frequency of patients in the LC and HCC groups was twice as much in CHC cases. HCC with DM2 have the greatest percentage above the 80th percentile of HOMA-IR, their quintiles distribution is inverted and HOMA-IR mean values are significantly higher in comparison with HCC without DM2 cases.DiscussionOur study shows that the association between IR and CLD begins in the early stages of liver fibrosis. DM2 increases HOMA-IR and IRI mean levels in HCC patients and these metabolic factors could play a major role in the link between diabetes mellitus and hepatocarcinoma
A MIP-and-refine matheuristic for smart grid energy management
Abstract In the last years we have witnessed an increasing interest in smart buildings, in particular for what concerns optimal energy management, renewable energy sources, and smart appliances. In this paper we investigate the problem of scheduling smart appliance operation in a given time horizon with a set of energy sources and accumulators. Appliance operation is modeled in terms of uninterruptible sequential phases with a given power demand, with the goal of minimizing the energy bill fulfilling duration, energy, and user preference constraints. A Mixed Integer Linear Programming (MIP) model and a greedy heuristic algorithm are given, intended to be used in a synergic way. We show how a general purpose (off-the-shelf) MIP refining procedure can effectively be used for improving, in short computing time, the quality of the solutions provided by the initial greedy heuristic. Computational results confirm the viability of the overall approach, in terms of both solution quality and speed
Alcohol and HCV Chronic Infection Are Risk Cofactors of Type 2 Diabetes Mellitus for Hepatocellular Carcinoma in Italy
Type 2 diabetes mellitus (DM2) has been associated with hepatocellular carcinoma (HCC) development. To study this relationship, we enrolled 465 HCC patients compared with 618 Cirrhotic cases and 490 Controls. The prevalence of DM2 is significantly higher in HCC patients with an Odds Ratio of 3.12 versus Controls. In HCC cases with alcohol abuse, the frequency of DM2 is the highest. In our HCC patients, when HCV infection is associated with alcohol abuse, the liver cancer develops earlier. In addition, multivariate analysis shows that alcohol consumption is an independent risk factor for HCC more relevant than HCV infection

Conscious Sedation in Dentistry for the Management of Pediatric Patients with Autism: A Narrative Review of the Literature
(1) Background: the variety of autism spectrum disorder makes the definition of guidelines
for dental care a challenging task. The aim of this review was to evaluate the literature concerning the
use of conscious sedation for dental treatments in pediatric autistic patients. (2) Methods: we searched
MEDLINE/PubMed, EMBASE, Cochrane databases in order to identify pertinent studies. The search
strategy was based on these areas of interest: autistic spectrum disorder, pediatric patients, dentistry,
tranquilizing agents, and conscious sedation. (3) Results: the search yielded 177 non-duplicated
articles, of which 24 articles were retrieved for full text review, and 2 were found to address our
review aim. The first paper was a retrospective study that included 83 autistic patients sedated
either with an oral premedication combined with nitrous oxide/oxygen inhalation or with nitrous
oxide/oxygen inhalation alone; the second article was a prospective trial on the effectiveness of
0.3 mg/kg of oral diazepam with 0.5 mg/kg of oral midazolam in 13 sedated uncooperative autistic
patients. (4) Conclusions: this review highlights the insufficiency of studies that can provide concrete
indications for the dental treatment in conscious sedation of pediatric patients with autism. New
studies are needed to better define the appropriate drugs, dosages, sedation level and evaluate
patient cooperation

W1778 Relationships Among Type 2 Diabetes Mellitus, Antidiabetic Therapy and Hepatocellular Carcinoma
Cancer risk among patients with type 2 diabetes mellitus: A population-based cohort study in northeastern Italy
Diabetes mellitus (DM) is associated with an elevated risk of cancer. The aim of this study was to assess cancer risk and survival in individuals with type 2 DM (T2DM) in Friuli Venezia Giulia, Italy. A retrospective population-based cohort study of 32,247 T2DM patients aged 40\u201384 years was conducted through a record linkage of local healthcare databases and cancer registry for the period 2002\u20132009. Standardized incidence ratios (SIRs) with 95% confidence intervals (95%CIs) and 5-year survival probabilities after T2DM and cancer diagnosis were computed. The SIRs for all cancers (n\u2005=\u20052069) was 1.28 (95%CI: 1.23\u20131.34). The highest SIRs were observed for cancers of the liver, female genital organs, small intestine, and pancreas. After 3 years from T2DM diagnosis, a reduced risk of prostate cancer (SIR\u2005=\u20050.73, 95%CI: 0.54\u20130.96) was found in men aged 65\u201374 years, and a higher risk for breast cancer (SIR\u2005=\u20051.24, 95%CI: 1.00\u20131.52) was found among T2DM female patients. The overall 5-year survival after T2DM was 88.7%. Furthermore, T2DM appeared to have a negative effect on survival of women with breast cancer. This population-based study confirmed that T2DM patients are at increased risk of several cancers, and of premature death in women with breast cancer
Pepsinogens to Distinguish Patients With Gastric Intestinal Metaplasia and Helicobacter pylori Infection Among Populations at Risk for Gastric Cancer
OBJECTIVES: The objectives of this study were to investigate the serum pepsinogen test for the prediction of OLGIM (Operative Link on Gastric Intestinal Metaplasia Assessment) stages in first-degree relatives (FDR-GC) of patients with gastric cancer (GC) and autoimmune chronic atrophic gastritis (ACAG).METHODS: In 67 consecutive patients with ACAG, 82 FDR-GC, and 53 controls (CTRL) without gastric disease (confirmed by biopsy), serum levels of pepsinogen 1 (PG1), pepsinogen 2 (PG2), G17, and the PG1/2 ratio were assessed by enzyme-linked immunosorbent assay kit. All ACAG patients had positive antiparietal cell antibody levels, estimated by indirect immunofluorescence. Biopsies taken in duplicate from the antrum, corpus, and fundus were stained with Giemsa for Helicobacter pylori detection. Endoscopic detection of metaplasia was confirmed by histological diagnosis. Histological classification of OLGIM stages was applied by using the criteria of severity and topography of intestinal metaplasia (IM).RESULTS: The highest discrimination capacity for distinguishing ACAG from other groups of patients was the gastrin G17 test. The lowest mean for PG1 and PG2 serum levels was found in ACAG. In multivariate analysis by age, PG1 and PG1/PG2 were independent prognostic factors for metaplasia, and PG2 also for the presence of a histological H. pylori infection. The serum PG1 level was significantly lower in individuals with IM at OLGIM stage >2 than in those with IM at OLGIM stage = 2 vs. 0-1 OLGIM stages, the receiver operating characteristic (ROC) curve at 47.9 ng/ml PG1 level reached a significant area under the curve (AUC) value (0.978, P= 2. Using a cutoff of 47.9 ng/ml, PG1 testing in FDR-GC and ACAG patients had a sensitivity of 95.83% and a specificity of 93.37. Although these results could be validated in a prospective study, the known importance of higher OLGIM stages in increasing the risk of GC development supports the rationale of proposing PG1 algorithm as a diagnostic tool for the selection of high-risk FDR-GC and ACAG patients at high-risk stages for subsequent detailed endoscopic examination to detect dysplasia and asymptomatic GC. In addition, serum PG1 and PG2 levels could stratify patients based on both H. pylori infection and OLGIM risk in consideration of the increased acknowledge regarding the role of H. pylori in the progression of gastritis to GC
