Acinetobacter baumannii is an opportunistic pathogen causing various nosocomial infections. The aim of this study was to characterize the molecular support of carbapenem-resistant A. baumannii clinical isolates recovered from four hospitals in Tripoli, Libya. Bacterial isolates were identified and antibiotic susceptibility testing was per-formed using automated system. Carbapenem resistance determinants were studied phenotypically using two dif-ferent techniques: E-test; chromogenic culture media. Polymerase chain reaction (PCR) amplification was used to determine the presence of bla OXA23 and blaOXA51 genes among isolates. A total of 119 isolates were characterized, overall the resistance prevalence was extremely high for aminoglycosides (79-96.6%), fluoroquinolones (94-96%), cephalosporins (96.6-100%) and carbapenemes (93.2-100%), all isolates were susceptible to colistin. In addition, 97.5% of isolates were identified as multidrug resistance (MDR). Varying degree of phenotypic detection of car-bapenemes was determined; highest levels of carbapenemes were detected using chromogenic media (76.5%) com-pared with E-test (45.4 %). The carbapenem resistance-encoding genes detected were blaOXA23 (84%) and blaOXA51 (73.1%); the highest occurrence of blaOXA23 was demonstrated in Tripoli’s Central Hospital (5/5; 100%) then in Tripoli Medical Center (44/51; 86.27%). The co-occurrence of these genes was demonstrated in (75/119; 63%) showing dissemination of carbapenemes resistance MDR A. baumannii in hospitals. This study shows that the high prevalence of OXA-23 contribute to antibiotic resistance in … arabic 14 English 113

GLUT4 translocation in response to insulin involves the PI3K/Akt pathway and IR mediated phosphorylation of CAP (SORBS1), and formation of the CAP:Cbl. These pathways act in a coordinated manner to regulate glucose, lipid and protein metabolism. In previous studies, T228A polymorphism of SORBS1 gene has been shown to be a protective factor for obesity, type-2 diabetes mellitus (T2DM), polycystic ovary (PCOs), and lacunars infarction. Objectives: The objective of this study was to investigate the association between this polymorphism and T2DM, gestational diabetes (GDM), and obesity. Methods: Genotyping was achieved by PCR-RELP in 227 individuals chosen randomly from the out patient’s clinics of Al-Jala maternity hospital of Tripoli and Gharian hospital, including: 63 T2DM patients, 59 GDM patients, 57 obese, 47 healthy control individuals from Libyan pregnant women population (North-West Region). Results: The results revealed that this polymorphism has no association with T2DM, GDM, and obesity in comparison with the control sample. Conclusion: T228A polymorphism of SORBS1 gene is not associated with the pathological conditions studied. arabic 15 English 98

The pattern of diabetic deaths in the medical wards of Tripoli Medical Centre was retrospectively studied. During a three‐year period, 575 diabetic deaths occurred, accounting for 26.2% of all medical deaths. The mean age at death was 65.33±12.7 years. Cardiovascular disease (183 [31.8%]), cerebrovascular accidents (102 [17.7%]) and infection (83 [14.4%]) were the most common complications associated with diabetic deaths. Other causes were malignancy (10%), liver cirrhosis (5.6%), and acute diabetic complications (5%). Forty‐five (7.8%) deaths unaccountable for may be due to other unknown causes. Factors predictive of mortality, such as admission diagnosis of hyperosmolar non‐ketotic state, cerebrovascular disease, acute coronary syndromes or infection were associated with poor prognosis. Admission hyperglycaemia, old age, renal dysfunction and prior stroke were also associated with poor admission outcome. The excess mortality, mainly due to atherosclerotic complications, is potentially preventable through implementation of serious approaches to the management of cardiovascular risk factors. arabic 8 English 64
