    This thesis aims to develop a framework for the UAE to activate its national innovation ecosystem. The present study was guided by the following research questions: What is the current nature of the national innovation ecosystem that exists in the UAE? What are the main drivers that influence or hinder a sustainable (educational) innovation-based national ecosystem? How can the UAE Government best promote and activate a successful national innovation ecosystem? These questions were answered using qualitative and quantitative methods to gather data about innovation in the UAE. A total of 24 semi-structured interviews were conducted and thematically analysed, representing the qualitative aspect of the study. Then, 207 descriptively analysed surveys were conducted, providing quantitative data. These were used to validate the qualitative findings. An initial draft of the national innovation framework was developed, which was validated through further semi-structured interviews with six influential policymakers from the UAE national ecosystem of innovation. Their input was considered carefully and used to refine the final version of the framework

    Emerging research findings suggest a potential relationship between smartphone use (SPU) and dry eye disease (DED), which has not been systematically reviewed. The aim of this study was to systematically review and synthesize evidence on the relationship between SPU and DED. A systematic search of Medline, EMBASE, CINAHL, and PsychINFO bibliographic databases from their inception to January 15, 2021. Study screening, full-text assessment, study selection and exclusion, data extraction, and quality assessment was performed independently by at least two review authors. Four studies were included in the review (3 cross-sectional studies and 1 nonrandomized clinical trial). A narrative synthesis of findings was used due to heterogeneity among study designs and measures of association summarizing the relationship between SPU and DED. All included studies were conducted in South Korea and included school children, college students, or young adults. Three of the 4 included studies showed an association between SPU and DED. There is some evidence that SPU is associated with DED. However, this evidence is limited by a small number of studies of satisfactory methodological quality. There is a great need for high-quality studies to further investigate the relationship between SPU and DED and identify mechanisms underlying this potential relationship. This information is important for raising public awareness about the negative effect of SPU on eye health and development of clinical guidelines for this potentially emerging SPU-driven eye condition.This research was funded by Qatar National Research Fund, Undergraduate Research Experience Program (UREP26-074-3-026). The funder had no role in study design; collection, analysis, and interpretation of data; writing the report; and the decision to submit the report for publication

    Genetic engineering to enhance microalgal-based produced water treatment with emphasis on CRISPR/Cas9: A review

    Get PDF
    In recent years, the increased demand for and regional variability of available water resources, along with sustainable water supply planning, have driven interest in the reuse of produced water. Reusing produced water can provide important economic, social, and environmental benefits, particularly in water-scarce regions. Therefore, efficient wastewater treatment is a crucial step prior to reuse to meet the requirements for use within the oil and gas industry or by external users. Bioremediation using microalgae has received increased interest as a method for produced water treatment for removing not only major contaminants such as nitrogen and phosphorus, but also heavy metals and hydrocarbons. Some research publications reported nearly 100% removal of total hydrocarbons, total nitrogen, ammonium nitrogen, and iron when using microalgae to treat produced water. Enhancing microalgal removal efficiency as well as growth rate, in the presence of such relevant contaminants is of great interest to many industries to further optimize the process. One novel approach to further enhancing algal capabilities and phytoremediation of wastewater is genetic modification. A comprehensive description of using genetically engineered microalgae for wastewater bioremediation is discussed in this review. This article also reviews random and targeted mutations as a method to alter microalgal traits to produce strains capable of tolerating various stressors related to wastewater. Other methods of genetic engineering are discussed, with sympathy for CRISPR/Cas9 technology. This is accompanied by the opportunities, as well as the challenges of using genetically engineered microalgae for this purpose.This work was supported by ExxonMobil funding (QUEX-CAS-EMRQ-20/21).

    Qatar is one of the biggest oil and gas producers in the world, coupled with it is challenging environmental conditions (high average temperature: >40 °C, low annual rainfall: 46.71 mm, and high annual evaporation rate: 2200 mm) harbors diverse microbial communities that are novel and robust, with the potential to biodegrade hydrocarbons. In this study, we collected hydrocarbon contaminated sludge, wastewater and soil samples from oil and gas industries in Qatar. Twenty-six bacterial strains were isolated in the laboratory from these samples using high saline conditions and crude oil as the sole carbon source. A total of 15 different bacterial genera were identified in our study that have not been widely reported in the literature or studied for their usage in the biodegradation of hydrocarbons. Interestingly, some of the bacteria that were identified belonged to the same genus however, demonstrated variable growth rates and biosurfactant production. This indicates the possibility of niche specialization and specific evolution to acquire competitive traits for better survival. The most potent strain EXS14, identified as Marinobacter sp., showed the highest growth rate in the oil-containing medium as well as the highest biosurfactant production. When this strain was further tested for biodegradation of hydrocarbons, the results showed that it was able to degrade 90 to 100% of low and medium molecular weight hydrocarbons and 60 to 80% of high molecular weight (C35 to C50) hydrocarbons. This study offers many promising leads for future studies of microbial species and their application for the treatment of hydrocarbon contaminated wastewater and soil in the region and in other areas with similar environmental conditions

    Nonlinear pattern of pulmonary tuberculosis among migrants at entry in Kuwait: 1997–2006

    <p>Abstract</p> <p>Background</p> <p>There is a paucity of published data on the pattern of pulmonary tuberculosis among migrant workers entering Middle Eastern countries particularly Kuwait. The objectives of this study were to use routine health surveillance data i) to estimate the prevalence of pulmonary tuberculosis among migrant workers at entry in Kuwait and ii) to determine the occurrence of any time trends in the proportions of pulmonary tuberculosis positive workers over the study period.</p> <p>Methods</p> <p>The monthly aggregates of daily number of migrants tested and the number of pulmonary tuberculosis cases detected during routine health examinations of migrant workers from tuberculosis high-prevalence countries were used to generate the monthly series of proportions (per 100,000) of pulmonary tuberculosis cases over 120 months between January 1, 1997 and December 31, 2006 and analysed using time series methods.</p> <p>Results</p> <p>The overall prevalence (per 100,000) of documented pulmonary tuberculosis cases among screened migrants was 198 (4608/2328582). Year-specific prevalence (per 100,000) of tuberculosis cases consistently declined from 456 (95% CI: 424 – 490) in 1997 to 124 (95% CI: 110 – 140) in 2002 before showing a steady increase up to 183 (95% CI: 169–197) in 2006. The second-order polynomial regression model revealed significant (<it>P </it>< 0.001) initial decline, followed by a significant (<it>P </it>< 0.001) increasing trend thereafter in monthly proportions of tuberculosis cases among migrant workers.</p> <p>Conclusion</p> <p>The proportions of documented tuberculosis cases among migrant workers showed a significant nonlinear pattern, with an initial decline followed by a significant increasing trend towards the end of the study period. These findings underscore the need to maintain the current policy of migrants' screening for tuberculosis at entry. The public health authorities in Kuwait and perhaps other countries in the region may consider complementing the current screening protocol with interferon-<it>γ </it>assays to detect migrants with latent <it>Mycobacterium tuberculosis </it>infection. An appropriate curative or preventive chemotherapy of detected tuberculosis cases may help in further minimizing the risk of local transmission of <it>M. tuberculosis</it>, while contributing in global efforts to control this public health menace.</p

    Background: The aim of this post hoc analysis of a large cohort study was to evaluate the association between night-time surgery and the occurrence of intraoperative adverse events (AEs) and postoperative pulmonary complications (PPCs). Methods: LAS VEGAS (Local Assessment of Ventilatory Management During General Anesthesia for Surgery) was a prospective international 1-week study that enrolled adult patients undergoing surgical procedures with general anaesthesia and mechanical ventilation in 146 hospitals across 29 countries. Surgeries were defined as occurring during \u2018daytime\u2019 when induction of anaesthesia was between 8:00 AM and 7:59 PM, and as \u2018night-time\u2019 when induction was between 8:00 PM and 7:59 AM. Results: Of 9861 included patients, 555 (5.6%) underwent surgery during night-time. The proportion of patients who developed intraoperative AEs was higher during night-time surgery in unmatched (43.6% vs 34.1%; P<0.001) and propensity-matched analyses (43.7% vs 36.8%; P=0.029). PPCs also occurred more often in patients who underwent night-time surgery (14% vs 10%; P=0.004) in an unmatched cohort analysis, although not in a propensity-matched analysis (13.8% vs 11.8%; P=0.39). In a multivariable regression model, including patient characteristics and types of surgery and anaesthesia, night-time surgery was independently associated with a higher incidence of intraoperative AEs (odds ratio: 1.44; 95% confidence interval: 1.09\u20131.90; P=0.01), but not with a higher incidence of PPCs (odds ratio: 1.32; 95% confidence interval: 0.89\u20131.90; P=0.15). Conclusions: Intraoperative adverse events and postoperative pulmonary complications occurred more often in patients undergoing night-time surgery. Imbalances in patients\u2019 clinical characteristics, types of surgery, and intraoperative management at night-time partially explained the higher incidence of postoperative pulmonary complications, but not the higher incidence of adverse events.
