Background: Multiple laboratory tests are used in the diagnosis and management of patients with diabetes mellitus. The quality of the scientific evidence supporting the use of these assays varies substantially. Approach: An expert committee compiled evidencebased recommendations for the use of laboratory analysis in patients with diabetes. A new system was developed to grade the overall quality of the evidence and the strength of the recommendations. A draft of the guidelines was posted on the Internet, and the document was modified in response to comments. The guidelines were reviewed by the joint Evidence-Based Laboratory Medicine Committee of the AACC and the National Academy of Clinical Biochemistry and were accepted after revisions by the Professional Practice Committee and subsequent approval by the Executive Committee of the American Diabetes Association. Content: In addition to the long-standing criteria based on measurement of venous plasma glucose, diabetes can be diagnosed by demonstrating increased hemoglobin A1c (HbA1c) concentrations in the blood. Monitoring of glycemic control is performed by the patients measuring their own plasma or blood glucose with meters and by laboratory analysis of Hb A1c. The potential roles of noninvasive glucose monitoring, genetic testing,and measurement of autoantibodies, urine albumin, insulin, proinsulin, C-peptide, and other analytes are addressed. Summary: The guidelines provide specific recommendations based on published data or derived from expert consensus. Several analytes are found to have minimal clinical value at the present time, and measurement of them is not recommended.

Mohammed Hariri Bakri(Mohammed Hariri Bakri ),Abdulla Ali Al Mazrouei(Abdulla Ali Al Mazrouei ),Albert Feisal Ismail(Albert Feisal Ismail ),Mohamad Idham Md Razak(Mohamad Idham Md Razak ),Geraldine De People&Global Business Association 2023 Global Business and Finance Review Vol.28 No.4

Purpose: This research examines the impact of four leadership behavior styles; directive, supportive, participative, and achievement-oriented. These four leadership behavior styles are retrieved from the Path goal theory, which considers the employee motivation determinants by the expectancy theory. Design/methodology/approach: The association between the leadership styles and behaviors suggested by the Path goal theory with employee motivation lacks the role of the entrepreneurial mindset factor, which stands on the thinking that enables the employee to overcome challenges, be decisive, and accept responsibility. This research tests the mediation effect of the entrepreneurial mindset factor to fill this gap and contributes significantly to the knowledge of leadership behavior styles. The study also validates the proposed conceptual framework using structural equations modeling, then uses smart PLS with the data collected from 341 employees from the UAE municipalities to test the constructed hypotheses of this research. Findings: The finding of this research revealed a positive and significant relationship between achievement-oriented style and employee motivation in the municipalities of the UAE, a positive and significant relationship between entrepreneurial mindset and employee motivation in the municipalities of the UAE, a positive and significant relationship between participative style and employee motivation in the municipalities of the UAE and positive and significant relationship between supportive style and employee motivation in the municipalities of the UAE. The mediation effect of the entrepreneurial mindset factor, there was a mediation of entrepreneurial mindset for the relationship between directive style and employee motivation. There is no mediation of entrepreneurial mindset for the relationship between achievement-oriented style and employee motivation, no mediation of entrepreneurial mindset for the relationship between participative style and employee motivation, and no mediation of entrepreneurial mindset for the relationship between supportive style and employee motivation. Research limitations/implications: The employees must be appreciated verbally or in writing for their activities in the municipalities to increase their powers and responsibilities and to provide training and career development opportunities. These are the primary leadership motivational factors that provide employees with psychological and social support rather than economic benefit. It can be stated that psycho-social motivation ties employees more. The findings can assist managers in determining which type of leadership style is most suitable in terms of outcomes, as well as how they can adjust their leadership styles to make them more successful and result-oriented. Originality/value: This research can be the first local empirical research to evaluate the organization's performance relationship between leadership behavior styles and the UAE municipality employees' motivation through an entrepreneurial mindset.

Purpose: The main purpose of this study is to investigate the behavioural intention of the millennials in Malaysia toward the acceptance of Islamic e-wallet usage using Unified Theory of Acceptance and Use of Technology(UTAUT) via Structural Equation Model. Design/methodology/approach: The data have been collected by the 384 millennials in Malaysia. A person has aged between 25 until 40 years old is considered the millennials group The method that used in this paper is the Unified theory of acceptance and use of technology (UTAUT). There will be five independent variables: performance expectancy, effort expectancy, social influence, facilitating condition, and Shariah-compliant. Shariah-compliant variables have been added to the study because the study investigates the Islamic e-wallet where it is needed the Shariah-compliant elements. Before the data is analysed into measurement, preliminary analysis such as Exploratory Factor Analysis (EFA) is conducted as well. Findings: The result showed that the performance expectancy (PE), effort expectancy (EE), social influence (SI) and Shariah complaint (SC) significantly affect the Islamic e-wallet acceptance among the millennials. In addition, the Shariah complaint has a strong effect on Islamic e-wallet acceptance. In contrast, facilitating condition (FC) showed no effect on Islamic e-wallet acceptance. In this study, all the requirements for model fit were achieved. The four exogenous constructs are performance expectancy (PE), effort expectancy (EE), social influence (SI) and facilitating condition (FC). The mediating construct is behavioural intention (BI) and the endogenous is user adoption (UA). All exogenous constructs show significant p-value except for effort expectancy (EE). Research limitation/implications: This paper offers important implications specifically for the digital economy as it is currently making its way throughout every aspect in the human life, be it social, religion, financial transaction, entertainment and many more. The impact of digital economy can be traced through the emergence of Fintech. One of the least academically discussed areas is the adoption of Islamic Fintech. This study is considered necessary to explore the prediction of consumer behaviour in Islamic Fintech intention, as part of digital economy. Originality/value: The paper fills the gap perceived within the existing literature of finance technology by showing Islamic financial technology (E-Wallet) intention via model measurement.

Portfolio Diversification Benefits of Cryptocurrencies and ASEAN-5 Stock Markets

Bakri Abdul KARIM,Aisyah ABDUL-RAHMAN,Josephine Yau Tan HWANG,Norlina KADRI 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.6

This paper examines the portfolio diversification benefits in the cryptocurrencies (Bitcoin, Ethereum, Ripple, Litecoin, Stellar and Dash) and ASEAN-5 stock markets (Malaysia, Indonesia, Singapore, Thailand and Philippines). Cointegration and Granger causality tests are used in this study for the period from August 2015 to October 2019. We found evidence of no cointegration among the cryptocurrencies. Thus, the cryptocurrencies market provides an opportunity for the potential benefits from portfolio diversification and hedging strategies. However, cointegration is found between cryptocurrencies and ASEAN-5 stock markets thus indicating limited portfolio diversification benefits in the long-run among these markets. In addition, the results also show that ASEAN-5 stock markets are going towards a greater integration among them which is in congruence with the previous studies. However, in the short-run, Granger causality tests show that Dash, Ethereum, Lite, Ripple and Stellar have no causality relationship with all ASEAN-5 stock markets and no causality is also found between Bitcoin and three of ASEAN-5 stock markets (Malaysia, Singapore and Philippines). Therefore, there still exists an opportunity for portfolio diversification between cryptocurrencies and ASEAN-5 stock markets in the short-run. The findings of this study suggest that crypto-investors, international investors and fund managers can diversify their investments in both cryptocurrencies and the ASEAN-5 stock markets.

The study investigates developing an Islamic student financing securitization model based on sukuk structures. This study employs sample of descriptive, analytical, and comparative analyses utilized to discuss a novel framework of Islamic securitization through the different structures of sukuk wakalah derived from asset securitization. The result served to investigate the use of Islamic student financing securitization in a Shariah-compliant manner, which would be implementable in Malaysia. It emphasized the sukuk structures based on the wakeel principle, which indicated a situation where a wakeel or representative appointment was made to manage a project on the behalf of the sukuk holder. The findings of this study supported the economic benefits obtained in the form of lower overall financing costs through the use of securitization for student financing in higher education. This paper offers important implications specifically for the creation of sukuk structures and issuing a highly graded and marketable sukuk, which are compliant towards global Shariah principles. The paper fills the gap perceived within the existing literature of Islamic finance by showing Islamic securitization via sukuk as a viable source of funds potential utilizable in stabilizing the securities market. It can also pose as a solution for securing a sustainable funding.

Improvement of biohistological response of facial implant materials by tantalum surface treatment

Bakri, Mohammed Mousa,Lee, Sung Ho,Lee, Jong Ho Korean Association of Maxillofacial Plastic and Re 2019 Maxillofacial Plastic Reconstructive Surgery Vol.41 No.-

Background: A compact passive oxide layer can grow on tantalum (Ta). It has been reported that this oxide layer can facilitate bone ingrowth in vivo though the development of bone-like apatite, which promotes hard and soft tissue adhesion. Thus, Ta surface treatment on facial implant materials may improve the tissue response, which could result in less fibrotic encapsulation and make the implant more stable on the bone surface. The purposes of this study were to verify whether surface treatment of facial implant materials using Ta can improve the biohistobiological response and to determine the possibility of potential clinical applications. Methods: Two different and commonly used implant materials, silicone and expanded polytetrafluoroethylene (ePTFE), were treated via Ta ion implantation using a Ta sputtering gun. Ta-treated samples were compared with untreated samples using in vitro and in vivo evaluations. Osteoblast (MG-63) and fibroblast (NIH3T3) cell viability with the Ta-treated implant material was assessed, and the tissue response was observed by placing the implants over the rat calvarium (n = 48) for two different lengths of time. Foreign body and inflammatory reactions were observed, and soft tissue thickness between the calvarium and the implant as well as the bone response was measured. Results: The treatment of facial implant materials using Ta showed a tendency toward increased fibroblast and osteoblast viability, although this result was not statistically significant. During the in vivo study, both Ta-treated and untreated implants showed similar foreign body reactions. However, the Ta-treated implant materials (silicone and ePTFE) showed a tendency toward better histological features: lower soft tissue thickness between the implant and the underlying calvarium as well as an increase in new bone activity. Conclusion: Ta surface treatment using ion implantation on silicone and ePTFE facial implant materials showed the possibility of reducing soft tissue intervention between the calvarium and the implant to make the implant more stable on the bone surface. Although no statistically significant improvement was observed, Ta treatment revealed a tendency toward an improved biohistological response of silicone and ePTFE facial implants. Conclusively, tantalum treatment is beneficial and has the potential for clinical applications.

Opportunistic Insights into Occupational Health Hazards Associated with Waterpipe Tobacco Smoking Premises in the United Kingdom

Al-Bakri, Ali,Jawad, Mohammed,Salameh, Pascale,al'Absi, Mustafa,Kassim, Saba Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.2

Background: Smokefree laws aim to protect employees and the public from the dangers of secondhand smoke. Waterpipe premises have significantly increased in number in the last decade, with anecdotal reports of poor compliance with the smokefree law. The literature is bereft of information pertaining to waterpipe premise employees. This study aimed to opportunistically gather knowledge about the occupational health hazards associated with working in waterpipe premises in London, England. Materials and Methods: Employees from seven convenience-sampled, smokefree-compliant waterpipe premises in London were observed for occupational activities. Opportunistic carbon monoxide (CO) measurements were made among those with whom a rapport had developed. Observations were thematically coded and analysed. Results: Occupational hazards mainly included environmental smoke exposure. Waterpipe-serving employees were required to draw several puffs soon after igniting the coals, thereby providing quality assurance of the product. Median CO levels were 27.5ppm (range 21-55ppm) among these employees. Self-reported employee health was poor, with some suggestion that working patterns and smoke exposure was a contributory factor. Conclusions: The smokefree law in England does not appear to protect waterpipe premise employees from high levels of CO. Continued concerns surrounding chronic smoke exposure may contribute to poor self-reported physical and mental wellbeing.

Sources of political parties’ campaign expenditure in Nigeria’s Fourth Republic: Examining the 2015 General Election

Babayo Sule,Bakri Mat,Mohd Azizuddin Mohd Sani,Saalah Yakubu Ibrahim 한국외국어대학교 국제지역연구센터 2019 International Area Studies Review Vol.22 No.4

A periodic election is a fundamental pillar and backbone of any democratic regime, and for a proper election to take place there must be some activities, most especially by parties and contestants to vote for them most especially competing to secure the electorates. These activities require huge expenditure from the parties and their financiers through campaigns, media advertisements and other related activities. The problem is that parties and their candidates are allowed, in Nigeria constitutionally and by the Electoral Act 2010, to source their campaign finance privately, which has led to illegal financing. The objective of this paper is to examine the sources of parties’ campaign expenditure in the Fourth Republic, taking the 2015 General Election as the case study. The research used a qualitative method of data collection and analysis where both primary and secondary sources were used. The primary source was an in-depth personal interview with some selected informants/participants from the categories of stakeholders in the electoral process, parties, and agencies responsible for regulating their activities. The secondary source was the use of available documents such as books, journals and Internet sources on the subject matter of the study. The data obtained were analysed and interpreted using thematic analytical interpretations from the informants’ views and the existing data in the field. The research discovered that there are basically six major sources of campaign expenditure for parties and that some of the sources are illegal and the spending has violated the regulations. The research recommends thorough supervision and monitoring of the sources of parties’ campaign expenditure and the spending process.

Spinal versus general anesthesia for Cesarean section in patients with sickle cell anemia

Mohamed H. Bakri,Eman A. Ismail,Gamal Ghanem,Mahmoud Shokry 대한마취통증의학회 2015 Korean Journal of Anesthesiology Vol.68 No.5

Background: Sickle cell anemia (SCA) increases the rate of maternal and fetal complications. This pilot study was designed to compare the maternal and fetal outcomes of spinal versus general anesthesia (GA) for parturients with SCA undergoing cesarean delivery. Methods: Forty parturients with known SCA scheduled for elective Cesarean delivery were randomized into spinal anesthesia (n = 20) and GA groups (n = 20). Perioperative hemodynamic parameters were recorded. Postpartum complications were followed up. Opioid consumption was calculated. Blood loss during surgery and the number of patients who received intraoperative or postpartum blood transfusion were recorded. Patient satisfaction with the type of anesthesia was assessed. The Apgar score at 1 and 5 min, neonatal admission to the intensive care unit, and mortality were also recorded. Results: Blood loss was significantly higher in the GA than spinal group (P = 0.01). However, the number of patients who received an intraoperative or postpartum blood transfusion was statistically insignificant. Significantly more patients developed intraoperative hypotension and bradycardia in the spinal than GA group. Opioid use during the first 24 h was significantly higher in the GA than spinal group (P < 0.0001). More patients had vaso-occlusive crisis in the GA than spinal group without statistical significance (P = 0.4). There was one case of acute chest syndrome in the GA group. No significant differences were observed in postoperative nausea and/or vomiting, patient satisfaction, or hospital length of stay. Neonatal Apgar scores were significantly better in the spinal than GA group at 1 and 5 min (P = 0.006 and P = 0.009, respectively). Neonatal intensive care admission was not significantly different between the two groups, and there was no neonatal mortality. Conclusions: Spinal anesthesia may have advantages over GA in parturients with SCA undergoing Cesarean delivery.

AUTOMATIC NEURAL NETWORK SYSTEM FOR VORTICITY OF SQUARE CYLINDERS WITH DIFFERENT CORNER RADII

Y.El-Bakry, Mostafa.,El-Harby, A.A.,Behery, G.M. Korean Society of Computational and Applied Mathem 2008 Journal of applied mathematics & informatics Vol.26 No.5

The neural networks (NNs) simulation has been designed to simulate and predict the vortex wavelength ${\lambda}_x^*$, lateral vortex spacing ${\lambda}_y^*$, and normalized maximum vorticity at the vortex center near the wake of square cylinders with different corner radii. The system was trained on the available data of the three cases, although this data is very little. Therefore, we designed the system to work in automatic way for finding the best network that has the ability to have the best test and prediction. The proposed system shows an excellent agreement with that of an experimental data in these cases. The technique has been also designed to simulate the other distributions not presented in the training set and predicted them with effective matching.
