Antibiotic resistance profiles in Helicobacter pylori strains isolated in Sicily (Italy)

The occurrence of extended-spectrum β-lactamase producing Shigella spp. in Tehran, Iran
2013
Background and Objectives: The emergence of extended-spectrum β-lactamase (ESBL)-producing Shigella spp. is of increasing clinical concern specially in children worldwide. The aim of this study was to investigate the occurrence of extended-spectrum β-lactamase producing Shigella spp. in Tehran, Iran. Materials and Methods: The study included all Shigella isolates recovered from pediatric patients aged less than 12 years admitted to a major pediatric hospital in Tehran, Iran, from 2008 to 2010. Bacterial identification, antimicrobial susceptibility testing, extended spectrum β-lactamases (ESBLs) screening and confirmatory tests were performed according to the standard guidelines. Conjugal tr…
Molecular Epidemiological Survey ofCitrobacter freundiiMisidentified asCronobacterspp. (Enterobacter sakazakii) andEnterobacter hormaecheiIsolated fr…

A total of 75 powdered infant milk formula (PIF) samples collected from pharmacies and drugstores in Western Sicily, Italy, and representative of 12 different brands were analyzed in this study to evaluate their microbiological quality. According to the U.S. Food and Drug Administration protocol, 32 samples out of 75 were contaminated by enterobacteria. Commercial biochemical API(r) 20E-system identification method indicated that six PIF samples were presumptively contaminated by Cronobacter spp., but further characterization by alpha-glucosidase based polymerase chain reaction (PCR) assay identification strongly suggested that these strains did not belong to the genus Cronobacter. Phylogen…
Antibiotic Susceptibility Patterns and Molecular Epidemiology of Metallo-β-Lactamase Producing Pseudomonas Aeruginosa Strains Isolated From Burn Pati…
2014
BACKGROUND: Failure in the treatment of burn patients infected with Pseudomonas aeruginosa could happen as a result of the acquisition of antibiotic resistance, including carbapenems. OBJECTIVES: The aim of the present study was to investigate the phenotypic and genotypic characteristics of the Pseudomonas aeruginosa strains, isolated from burn patients. PATIENTS AND METHODS: During a 12 month period, in this cross-sectional study, two hundred seventy strains of Pseudomonas aeruginosa were isolated from the burn patients in Ghotbeddin Burn Hospital, Shiraz, Iran. Screening for the carbapenem resistance in the isolates was carried out by the E test method. Sensitivity patterns of metallo-β-l…
Phylodynamic Analysis and Implication of HCV Genotype 4 Variability on Antiviral Drug Response and T-Cell Recognition.
2020
Therapies for HCV care could change the prevalence and the geographic distribution of genotypes due to differences in Sustained Virologic Response (SVR). In this scenario, uncommon genotypes/subtypes, such as genotype 4, could spread from high-risk groups, replacing genotypes eradicated by antiviral drugs. Genotype eradication is also strongly influenced by the CD8+ T cell response. In this study, the genetic variability in HCV genotype 4 strains obtained from a cohort of 67 patients naï
Consensus On Women'S Health Aspects Of Polycystic Ovary Syndrome (Pcos)
2012
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in females with a high prevalence. The etiology of this heterogeneous condition remains obscure and its phenotype expression varies. Two, widely cited, previous ESHRE/ASRM-sponsored PCOS consensus workshops focused on diagnosis (published in 2004) and infertility management (published in 2008). The present third PCOS consensus paper summarizes current knowledge and identifies knowledge gaps regarding various women's health aspects of PCOS. Relevant topics addressed-all dealt with in a systematic fashion-include adolescence, hirsutism and acne, contraception, menstrual cycle abnormalities, quality of life, ethnicity, preg…

Obesity: A main factor of metabolic syndrome?
2006
The metabolic syndrome (MS) is a common metabolic disorder that has been recently related to the increasing prevalence of obesity. The disorder is defined in various ways, but in the near future a new definition(s) will be applicable worldwide. The pathophysiology has been largely attributed, in the past years, to insulin-resistance, even if several epidemiological and pathophysiological data are attractive to indicate visceral obesity as a main factor in the occurrence of the MS, promoting new definitions and re-valuation of the pathogenesis of this syndrome. In this review, we have analyzed the role of visceral obesity in the new definition of the MS such as the pathophysiological role of…
Exercise in obesity management
2011
Obesity is considered a global epidemic by the World Health Organization in both developed and developing countries. It is associated with a higher risk of cardiovascular disease, diabetes mellitus, cancer and other clinical conditions. Visceral fat is the major responsible for metabolic complications, such as insulin-resistance, and it acts as an endocrine organ producing adipokines involved in lipidic and glycaemic metabolism. TNF-α and IL-6, produced by adipose tissue, increase NADPH oxidase activity activating protein kinase C and NFκB leading to an higher oxidative stress. The obesity management includes physical activity: aerobic training improves lipid profile and insulin sensitivity…
HEPATIC STEATOSIS IS ASSOCIATED WITH SEVERE FIBROSIS IN PATIENTS WITH CHRONIC HEPATITIS B
2010
Background and aim: Steatosis and insulin resistance (IR) are the major disease modifying in patients with chronic hepatitis C (CHC). Only few studies evaluated these features in patients with chronic hepatitis B (CHB). We aimed to assess the prevalence and the characteristics of steatosis and IR in CHB patients, compared to CHC subjects, and to evaluate the potential association between these features and fibrosis severity. Material and methods: 170 consecutive patients with CHB (28 HBeAg positive, 128 HBeAg negative, and 14 HBeAg negative/anti-HDV positive), and 170 sex, age and BMI matched genotype 1 CHC patients were evaluated by liver biopsy and metabolic measurements, including IR, by…
