    AbstractMycoplasma hominis (MH) and Ureaplasma urealyticum (UU) are important members of genital Mycoplasmas. They are implicated in urogenital infections and complicated pregnancy (chorioamnionitis, preterm delivery, abortion, and preterm birth) as well as bacterial vaginosis and cervicitis. The administration of antimicrobial agents to pregnant women with preterm rupture of the membranes (PROM) may extend the gestation period and decrease the risks of associated complications and neonatal infections. Despite empirical therapy is the rule in cases suspected to have genital infection in Egypt, the surveillance of the susceptibilities of used antibiotics is mandatory to ensure treatment efficacy and good prevention of any possible complications. This study aimed to assess the infection rate of genital Mycoplasmas (MH and UU) among pregnant females and their antimicrobial susceptibility pattern to provide a provisional idea about the effectiveness of antibiotics used empirically to treat cases of genital infections in pregnant women. High vaginal swabs of 50 pregnant females were examined using Mycoplasma IES kit, for identification of UU and MH. The kit also provides the antimicrobial susceptibility results for 12 antimicrobials of five different classes. UU and MH were detected in 26/50 (52%), and 7/50 (14%) of cases respectively, of which 5 cases showed mixed infection with both organisms. UU was most sensitive to quinolones (90–95%), followed by tetracyclines (80–85%). The least sensitivity was detected with chloramphenicol and clindamycin (40% and 30% respectively). The two MH isolates (100%) were sensitive to the three tested quinolones in addition to clindamycin and thiamphenicol. MH showed 100% sensitivity to clindamycin and 75% of UU isolates were sensitive to azithromycin. Further studies are needed to detect any future changes in the susceptibility pattern for these drugs or other antibiotics

    Impact of Nurses’ Work Patterns on Nurses and Patients in Critical Care and Toxicology Care Units of Alexandria University Hospitals

    Get PDF
    Background: Nowadays, there are difficulties in recruiting and retaining nursing staff with increasing pressures and demands on nurses working in critical care areas. The role of nursing care in patients' safety and healthcare outcomes has led to increased interest in measuring and reporting nurses’ work patterns and their consequences on nurses and patients. Objectives:  Describe nurses’ work patterns and their impacts on nurses and patient outcomes. Methods: Self-report forms were used to collect data regarding nurses’ time spent on direct and indirect nursing activities, non- nursing care and personal activities as well as care left undone. Questionnaires were used to measure stress, tension, conflict, nurses’ intent to leave, nurses' satisfaction and  patient satisfaction  Results: nurses spent their working time on direct nursing care (36.64 %); indirect nursing care (28.18 %), non-nursing care (30.64 %) and personal activities ( 4.7%). Profile of direct and indirect patient care and personal activities increased in night shifts, while the profile of non-nursing tasks increased in morning shifts.  There was a positive correlation between care left undone and three non-nursing tasks. Besides, there was a positive correlation between left care undone, non-nursing duties and four nursing job outcomes. There also was a negative correlation between care left undone, non-nursing tasks and nurses' and patients' satisfaction.  Conclusion:  the study focused on the importance of direct patient care on improving quality of care and patient safety. Reducing the performance of non-nursing duties by nurses and decreasing care left undone will most likely result in greater nurses’ and patients’  satisfaction, reduced stress, tension, and conflict and decreased numbers of  nurses’ leaving their jobs.

    Production of Cold-Active Lipase by Free and Immobilized Marine Bacillus cereus HSS: Application in Wastewater Treatment

    Get PDF
    Lipases are enzymes that have the potential to hydrolyze triacylglycerol to free fatty acids and glycerol and have various applications. The aim of the present study was to isolate and screen marine bacteria for lipase production, optimize the production, and treat wastewater. A total of 20 marine bacterial isolates were obtained from the Mediterranean Sea and were screened for lipase production. All isolates were found to have lipolytic ability. The differences between the isolates were studied using RAPD-PCR. The most promising lipase producer (isolate 3) that exhibited the highest lipolytic hydrolysis (20 mm) was identified as Bacillus cereus HSS using 16S rDNA analysis and had the accession number MF581790. Optimization of lipase production was carried out using the Plackett–Burman experimental design with cotton seed oil as the inducer under shaking conditions at 10°C. The most significant factors that affected lipase production were FeSO4, KCl, and oil concentrations. By using the optimized culture conditions, the lipase activity increased by 1.8-fold compared with basal conditions. Immobilization by adsorption of cells on sponge and recycling raised lipase activity by 2.8-fold compared with free cells. The repeated reuse of the immobilized B. cereus HSS maintained reasonable lipase activity. A trial for the economic treatment of oily wastewater was carried out. Removal efficiencies of biological oxygen demand, total suspended solids, and oil and grease were 87.63, 90, and 94.7%, respectively, which is promising for future applications

    The aim of this study was to reach a consensus on an updated version of the recommendations for the diagnosis and Treat-to-Target management of osteoporosis that is effective and safe for individuals with chronic kidney disease (CKD) G4-G5D/kidney transplant. Delphi process was implemented (3 rounds) to establish a consensus on 10 clinical domains: (1) study targets, (2) risk factors, (3) diagnosis, (4) case stratification, (5) treatment targets, (6) investigations, (7) medical management, (8) monitoring, (9) management of special groups, (10) fracture liaison service. After each round, statements were retired, modified, or added in view of the experts' suggestions, and the percent agreement was calculated. Statements receiving rates of 7-9 by more than 75% of experts' votes were considered as achieving consensus. The surveys were sent to an expert panel ( = 26), of whom 23 participated in the three rounds (2 were international experts and 21 were national). Most of the participants were rheumatologists (87%), followed by nephrologists (8.7%), and geriatric physicians (4.3%). Eighteen recommendations, categorized into 10 domains, were obtained. Agreement with the recommendations (rank 7-9) ranged from 80 to 100%. Consensus was reached on the wording of all 10 clinical domains identified by the scientific committee. An algorithm for the management of osteoporosis in CKD has been suggested. A panel of international and national experts established a consensus regarding the management of osteoporosis in CKD patients. The developed recommendations provide a comprehensive approach to assessing and managing osteoporosis for all healthcare professionals involved in its management.

    Association of Spermatogenic Failure with the b2/b3 Partial AZFc Deletion

    Get PDF
    Infertility affects around 1 in 10 men and in most cases the cause is unknown. The Y chromosome plays an important role in spermatogenesis and specific deletions of this chromosome, the AZF deletions, are associated with spermatogenic failure. Recently partial AZF deletions have been described but their association with spermatogenic failure is unclear. Here we screened a total of 339 men with idiopathic spermatogenic failure, and 256 normozoospermic ancestry-matched men for chromosome microdeletions including AZFa, AZFb, AZFc, and the AZFc partial deletions (gr/gr, b1/b3 and b2/b3)

    Importance: Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child's life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale. Objectives: To report the retinoblastoma stage at diagnosis in patients across the world during a single year, to investigate associations between clinical variables and national income level, and to investigate risk factors for advanced disease at diagnosis. Design, Setting, and Participants: A total of 278 retinoblastoma treatment centers were recruited from June 2017 through December 2018 to participate in a cross-sectional analysis of treatment-naive patients with retinoblastoma who were diagnosed in 2017. Main Outcomes and Measures: Age at presentation, proportion of familial history of retinoblastoma, and tumor stage and metastasis. Results: The cohort included 4351 new patients from 153 countries; the median age at diagnosis was 30.5 (interquartile range, 18.3-45.9) months, and 1976 patients (45.4%) were female. Most patients (n = 3685 [84.7%]) were from low- and middle-income countries (LMICs). Globally, the most common indication for referral was leukocoria (n = 2638 [62.8%]), followed by strabismus (n = 429 [10.2%]) and proptosis (n = 309 [7.4%]). Patients from high-income countries (HICs) were diagnosed at a median age of 14.1 months, with 656 of 666 (98.5%) patients having intraocular retinoblastoma and 2 (0.3%) having metastasis. Patients from low-income countries were diagnosed at a median age of 30.5 months, with 256 of 521 (49.1%) having extraocular retinoblastoma and 94 of 498 (18.9%) having metastasis. Lower national income level was associated with older presentation age, higher proportion of locally advanced disease and distant metastasis, and smaller proportion of familial history of retinoblastoma. Advanced disease at diagnosis was more common in LMICs even after adjusting for age (odds ratio for low-income countries vs upper-middle-income countries and HICs, 17.92 [95% CI, 12.94-24.80], and for lower-middle-income countries vs upper-middle-income countries and HICs, 5.74 [95% CI, 4.30-7.68]). Conclusions and Relevance: This study is estimated to have included more than half of all new retinoblastoma cases worldwide in 2017. Children from LMICs, where the main global retinoblastoma burden lies, presented at an older age with more advanced disease and demonstrated a smaller proportion of familial history of retinoblastoma, likely because many do not reach a childbearing age. Given that retinoblastoma is curable, these data are concerning and mandate intervention at national and international levels. Further studies are needed to investigate factors, other than age at presentation, that may be associated with advanced disease in LMICs
