Despite the relative abundance of sunny weather, surprisingly, there is increasing evidence that vitamin D deficiency is extremely prevalent in females of reproductive age in Middle East countries. There is also increasing interest in the non-classical roles of vitamin in health and disease including its relation to incidence of gestational diabetes, its impact on glycaemic control in diabetes mellitus, and its association with some complications of pregnancy like preeclampsia. The objective of this study was to estimate the prevalence of Vitamin D deficiency in pregnant diabetic patients in west Libya and analyse potential links to socioeconomic and cultural factors. This is a cross sectional observational study. Random plasma was collected form expected mothers attending the Antenatal Diabetes Clinic at Tripoli’s Main Maternity Hospital. Demographics and socioeconomic and cultural factors were recorded at the same time. Samples were analysed for vitamin D level and biochemical screening panel. Vitamin D level was obtained from 160 patients (mean age 35 years). Over all 95 % of the study population had vitamin D levels below normal (defined as vitamin D level of < 20 ng/mL). Results were subcategorised into severe deficiency ( 30 ng/ml, only 1.3%, 2 patients). All patients were taking daily vitamin D Supplements at a dose of 400 IU as per hospital policy. Vitamin D deficiency is extremely prevalent in pregnant diabetic patients in Libya. There is no clear association with socioeconomic risk factors like employment, type of accommodation or geographic distribution. However, most of the study population had life style characterized by minimal exposure to direct sun arabic 11 English 70

Background and Aims: Despite the well‑known association between human papillomavirus (HPV) and cervical cancer, yet there are no available data concerning the prevalence of HPV and its type distribution among Libyan women. The aim of this study was to investigate the prevalence of the most common high‑risk HPV types 16 and 18 among Libyan women in Tripoli and to compare it with the cytological findings of the cervix. Methods: A total of 132 cervical samples were collected from women who sought medical attention at the gynecology outpatient clinic of the Tripoli University Hospital and other gynecology private clinics in Tripoli region. Cervical cytological status was classified according to the Bethesda System 2014. Quantitative polymerase chain reaction was used to facilitate the specific detection of HPV types 16 and/or 18. Results: The cytopathological examination showed that 92.4% of women had normal cervical cytology (n = 122/132) and 7.5% (n = 10/132) of them had cervical lesions. The overall prevalence of the most common oncogenic HPV types was 4.5%, as only six samples (n = 6/132) were confirmed of harboring HPV‑DNA. Concerning the cytological status of the cervix, HPV‑DNA was not found (0%) in women with a normal cervix, and it was present in 60% of women with cervical lesions. The high‑risk HPV type 16 was the exclusive type among our all positive samples, with no detection of HPV type 18 among all our recruited subjects. Conclusion: Even though our findings showed a low overall prevalence of high‑risk HPV types among Libyan women, the burden of HPV 16 among women with cervical lesions highlights the need to raise attention toward expanding research about HPV and adopt measures to prevent cervical cancer by vaccination and national screening program. The introduction of HPV‑DNA testing in cervical cancer management will greatly benefit early‑stage HPV detection and help prevent cervical lesions from progression to cancer. arabic 15 English 81

Efficient extraction of genomic DNA (gDNA) from biological materials found in harsh environments is the first step for successful forensic DNA profiling. This study aimed to evaluate two methods for DNA recovery from animal tissues (livers, muscles), focusing on the best storage temperature for DNA yield in term of quality, quantity, and integrity for use in several downstream molecular techniques. Six male Swiss albino mice were sacrificed, liver and muscle tissues (n=32) were then harvested and stored for one week in different temperatures, -20C, 4C, 25C and 40C. The conditioned animal tissues were used for DNA extraction by Chelex-100 method or NucleoSpin Blood and Tissue kit. The extracted gDNA was visualized on 1.5% agarose gel electrophoresis to determine the quality of gDNA and analysed spectrophotometrically to determine the DNA concentration and the purity. Both methods, Chelex-100 and NucleoSpin Blood and Tissue kit found to be appropriate for yielding high quantity of gDNA, with the Chelex100 method yielding a greater quantity (P < 0.045) than the kit. At -20C, 4C, and 25C temperatures, the concentration of DNA yield was numerically lower than at 40C. The NucleoSpin Blood and Tissue kit produced a higher (P=0.031) purity product than the Chelex-100 method, particularly for muscle tissues. The Chelex-100 method is cheap, fast, effective, and is a crucial tool for yielding DNA from animal tissues (livers, muscles) exposed to harsh environment with little limitations.
