World Journal of Hepatology 2017年第23期9卷 1001-1007页

作者： Amal Ahmed Mohamed zainab A ali-Eldin Tamer A Elbedewy Magdy El-Serafy Fatma A ali-Eldin Hossameldin Abdel Aziz Biochemistry Department National Hepatology and Tropical Medicine Research Institute Department of Internal Medicine Faculty of MedicineAin Shams University Department of Internal Medicine Facultyof MedicineTanta University Department of Tropical Medicine Faculty of MedicineCairo University Department of Tropical Medicine Faculty of MedicineAin Shams University

To assess the role of some circulating miRNAs (miR-23a, miR-203, miR338, miR-34, and miR-16) as tumor markers for diagnosis of hepatocellular carcinoma (HCC). METHODSOne hundred and seventy-one subjects were enrolled, 57 patients with HCC, 57 patients with liver cirrhosis (LC) and 57 healthy subjects as control group. Severity of liver disease was assessed by Child Pugh score. Tumor staging was done using Okuda staging system. Quantification of Micro RNA (miR-23a, miR-203, miR338, miR-34, and miR-16) was performed. RESULTSAll studied miRNA showed significant difference between HCC and cirrhotic patients in comparison to healthy control. miR-23a showed statistically significant difference between HCC and cirrhotic patients being higher in HCC group than cirrhotic. miR-23a is significantly higher in HCC patients with focal lesion size equal or more than 5 cm, patients with multiple focal lesions and Okuda stage III. At cutoff value ≥ 210, miR-23a showed accuracy 79.3% to diagnose HCC patients with sensitivity 89.47% and specificity about 64.91%. At cut off level ≥ 200 ng/mL, serum alpha fetoprotein had 73.68% sensitivity, 52.63% specificity, 43.75% PPV, 80% NPV for diagnosis of HCC. CONCLUSIONMicroRNA 23a can be used as a screening test for early detection of HCC. Also, it is related to larger size of tumour, late Okuda staging and multiple hepatic focal lesions, so it might be a prognostic biomarker.

Psychological and Mental Health among Isolated Hospitalized Suspected and Confirmed COVID-19 Patients, Qatif Central Hospital, Eastern Province, Saudi Arabia: A Single-Center Descriptive Study

引用

Open Journal of Internal Medicine 2020年第3期10卷 245-255页

作者： Alya Hassan Alhajjaj Taaweel Hussain Al Abduljaber zainab ali Alsadeq Fatimah Lateef Alkhabbaz Hoor Hussain Alobaidan Fatimah ali Al Saeed Jumana Mansour Al-Jishi Ghada ali Aljanobi Internal Medicine Department Qatif Central Hospital Al Qatīf Saudi Arabia Psychiatry Department Erada Complex for Mental Health Al Dammam Saudi Arabia

Introduction: During COVID-19 pandemic, isolation and quarantine as preventive measures have been implemented. Isolation is often a bad experience for isolated people and it could affect the psychological and mental health. Objectives: To study the impact of isolation on the psychological and mental health of isolated hospitalized suspected and confirmed COVID-19 patients. Material & Methods: A single-center cohort, descriptive survey involving isolated confirmed and suspected COVID-19 patients in Qatif central hospital, Eastern province, Saudi Arabia. The study was conducted between March 22 and April 18, 2020. Information was collected through an online Arabic-language questionnaire. Our sample included both male and female. Anxiety and depression symptoms during hospitalization were evaluated with the Hospital Anxiety and Depression Scale. Results: A total of 52 questionnaires were returned completed. The majority of the respondents were females (65.4%). Most of the participants were less than 60 years of age (90.4%). Three patients were known to have previous mental illness. About two-thirds of the participants were isolated in shared rooms. The duration of isolation was less than 10 days in 72.3% of our sample. Borderline and abnormal scores for depression and anxiety were observed in about 38.4%, and 17.3% of patients, respectively. Three patients had both abnormal depression and anxiety scores. Conclusion: Isolation for contagious infections such as COVID-19 could cause severe psychological health problems, though this was not supported by our study due to the small sample size. Further studies are needed to address this important issue which results from isolation during infectious outbreaks.

Acute Transverse Myelitis in Pregnancy—A Case Report and a Literature Review

引用

Open Journal of Obstetrics and Gynecology 2024年第9期14卷 1512-1521页

作者： Huda Abbas ali Isa Fatema Hasan zainab Mohd Al Aswad Naeema Ahmed Abdulkareem Salmaniya Medical Complex Manama Bahrain Ob Gyn Faculty Arabian Gulf University Manama Bahrain

Purpose: This case report highlights a rare instance of a 26-week pregnant woman presenting with limb numbness, diagnosed with acute transverse myelitis (ATM) following COVID-19 vaccination. Notably, she tested positive for neuromyelitis optica (NMO) but did not exhibit the typical symptoms of blurred vision. Methods: Data were collected from I Seha in governmental hospitals in Bahrain, providing a comprehensive overview of the patient’s clinical journey. Results: The patient was treated with carbamazepine, steroids, and clexane, leading to the successful delivery of a healthy baby at 34 weeks. However, two years postpartum, she reported new episodes of blurred vision and numbness. Subsequent treatment with Rituximab resulted in significant improvement, with a diagnosis of Devic’s disease established. Conclusion: Acute transverse myelitis is a rare condition, particularly during pregnancy, and in this case, symptoms of Devic’s disease were masked by the absence of blurred vision. This condition predominantly affects females in their 20s during childbearing years and can lead to complications such as premature delivery. Effective management includes steroids and antiepileptic drugs, with clexane playing a crucial role in preventing embolisms. A delivery mode may vary based on obstetric factors, and MRI remains the gold standard for diagnosis. Close follow-up is essential for optimal patient outcomes.

A comparative study of Fungi (yeast and moulds) and their toxic metabolites was carried out on offal and muscles of freshly fried and stored Sallah meats from rams, bulls, goats and camels slaughtered for sacrifice in Danbatta Local Government Area, Kano State, Nigeria. The objective was to determine the effects of frying and four weeks storage at ambient temperatures on the mycological loads of the fried and stored meats. A total of seventy two (72) samples of muscles and offal were collected from six different and randomly selected households that slaughtered and fried any of the four animals during that period. The samples were analyzed immediately as freshly fried, and then stored for a period of four weeks during which analyses were conducted at the second and fourth weeks. An analysis of variance (ANOVA) was used to compare between the fungal loads and the toxin contents in the stored meat. Results revealed the presence of Mucor, Rhizopus stolonifer, Aspergillus niger, Saccharomycetes, Penicilium spp and Aspergillus flavus;and that, Aspergillus flavus and

Generation of Electricity by Electrogenic Bacteria in a Microbial Fuel Cell Powered by Waste Water

引用

Advances in Bioscience and Biotechnology 2016年第7期7卷 329-335页

作者： Zakira Naureen zainab ali Rashid Al Matani Miyassa Nasser Al Jabri Saif Khalfan Al Housni Syed Abdullah Gilani Fazal Mabood Saima Farooq Javid Hussain Ahmed Al Harrasi Department of Biological Science and Chemistry University of Nizwa Nizwa Oman

The present study aimed at isolation characterization and evaluation of electrogenic bacteria for electricity generation using waste water. In this context, waste water samples were collected from University of Nizwa waste water treatment plant. A total of eight distinct bacterial isolates were isolated from these samples by serial dilution and plating on LB Agar medium. The bacterial isolates were than grown at different temperatures and pH. DNA from bacterial samples was isolated and 16S rRNA gene amplification was carried out. The 16S rRNA gene PCR products were directly sequenced and the resulting sequence was blasted using BLASTn. Based on BLAST results, the bacterial strains were identified. The bacteria were used in different combinations to generate electricity from waste water in microbial fuel cells constructed using plastic bottles. The microbial isolates were found to produce varying levels of currents and their electrogenic potential in waste water was observed to increase with the passage of time.
