risk factors management and outcome of subtypes of ischemic stroke a stroke registry from the arabian Gulf
Journal of the Neurological Sciences, 2011Co-Authors: Dirk Deleu, Jihad Inshasi, Naveed Akhtar, Thomas Vurgese, Manorama Rajan, Moudi Almutairy, Ahmed Zayed, George Paulose, Kassid Nouri, A ThussuAbstract:Abstract Background Data on the determinants and outcome of ischemic stroke (IS) from the Arabian Gulf Countries (AGC) are still scanty. The aim of this study was to characterize IS in six large stroke centers on the Arabian peninsula. Methods IS subtypes were evaluated in four AGC from January 2006 to December 2007 in a large prospective multicenter hospital-based stroke registry including demographics, baseline risk factors, outcome and management. Results A total of 780 patients with IS were included. Mean age was 58.9 years (63.7% males). Large-artery atherosclerosis (LAA) (38.1%) was the most common subtype followed by lacunar stroke (LS)(34.7%), cardioembolic stroke (CE)(13.5%) and other determined causes (7%). LAA and CE were both more commonly observed over the age of 70. LAA showed a higher male preponderance, and the highest prevalence of hypertension, diabetes, obesity and ischemic heart disease among all subtypes. Obesity was a risk factor for both LAA and CE. Anterior circulation stroke was significantly more affected in LAA (21.2%), CE (19%) and LS (15.1%) subtype of stroke than in posterior circulation strokes (4.4%, 2.9% and 2.8%, respectively) (p Conclusions Demographically, our data are different from those in Western registries but the distribution of stroke subtypes is comparable. Compared to Asian registries the ratio LS versus LAA was much lower. For the first time these data allow to study the IS profile in this population.

multiple sclerosis in the arabian Gulf Countries a consensus statement
Journal of Neurology, 2013Co-Authors: Saeed Bohlega, Abdel Rahman Al Tahan, Abu Bakr Madani, Hussien Qahtani, Jihad Inshasi, Peter RieckmannAbstract:The epidemiology of multiple sclerosis (MS) is rapidly changing in many parts of the world. Based on the Kurtzke classification, the Arabian Gulf Region is located in a low-risk zone for MS; however, recent studies suggest a moderate-to-high prevalence nearby (31–55 MS per 10,0000 individuals), with an increase in incidence in recent years. The relapsing-remitting disease course ratio is 2.5:1 versus the primary progressive type. In a geographic area that was previously associated with low prevalence; the recent high prevalence and fast rising incidence of MS in the Gulf Countries, encouraged the neurologists of this region to meet in a consensus panel, in order to share our latest findings in terms of MS epidemiology and consent on MS management in the Arabian Gulf. Therefore 20 key opinion leader neurologists and MS experts representing various Countries of the Arabian Gulf have met in Dubai on the 2 and 3 February 2012, they shared their latest epidemiological findings, discussed recent MS aspects in the region, and consented on MS management relevantly to this geographic area.

rates of catheter associated urinary tract infection in tertiary care hospitals in 3 arabian Gulf Countries a 6 year surveillance study
American Journal of Infection Control, 2016Co-Authors: Wafa Al Nasser, Aiman Elsaed, Amina Aljardani, Abdulhakeem O Althaqafi, Huda Alansari, Jameela AlsalmanAbstract:Background The true burden of catheter-associated urinary tract infections (CAUTIs) remains largely unknown because of a lack of national and regional surveillance reports in Gulf Cooperation Council (GCC) Countries. The purpose of this study was to estimate location-specific CAUTI rates in the GCC region and to compare them with published reports from the U.S. National Healthcare Safety Network (NHSN) and the International Nosocomial Infection Control Consortium (INICC). Methods CAUTI rates and urinary catheter utilization between 2008 and 2013 were calculated using NHSN methodology pooled from 6 hospitals in 3 GCC Countries: Saudi Arabia, Oman, and Bahrain. The standardized infection ratios of the CAUTIs were compared with published reports of the NHSN and INICC. Results A total of 286 CAUTI events were diagnosed during 6 years of surveillance, covering 89,254 catheter days and 113,807 patient days. The overall CAUTI rate was 3.2 per 1,000 catheter days (95% confidence interval, 2.8-3.6), with an overall urinary catheter utilization of 0.78. The CAUTI rates showed a wide variability between participating hospitals, with approximately 80% reduction during the study. The overall compliance with the urinary catheter bundle implementation during the second half of the study was 65%. The risk of CAUTI in GCC hospitals was 35% higher than the NHSN hospitals, but 37% lower than the INICC hospitals. Conclusions CAUTI rates pooled from a sample of GCC hospitals are quite different from rates in both developing and developed Countries.

ventilator associated pneumonia rates in critical care units in 3 arabian Gulf Countries a 6 year surveillance study
American Journal of Infection Control, 2016Co-Authors: Aiman Elsaed, Amina Aljardani, Abdulhakeem O Althaqafi, Huda Alansari, Jameela Alsalman, Zaina Al MaskariAbstract:Background Data estimating the rates of ventilator-associated pneumonia (VAP) in critical patients in Gulf Cooperation Council (GCC) Countries are very limited. The aim of this study was to estimate VAP rates in GCC hospitals and to compare rates with published reports of the U.S. National Healthcare Safety Network (NHSN) and International Nosocomial Infection Control Consortium (INICC). Methods VAP rates and ventilator utilization between 2008 and 2013 were calculated from aggregate VAP surveillance data using NHSN methodology pooled from 6 hospitals in 3 GCC Countries: Saudi Arabia, Oman, and Bahrain. The standardized infection ratios of VAP in GCC hospitals were compared with published reports of the NHSN and INICC. Results A total of 368 VAP events were diagnosed during a 6-year period covering 76,749 ventilator days and 134,994 patient days. The overall VAP rate was 4.8 per 1,000 ventilator days (95% confidence interval, 4.3-5.3), with an overall ventilator utilization of 0.57. The VAP rates showed a wide variability between different types of intensive care units (ICUs) and were decreasing over time. After adjusting for the differences in ICU type, the risk of VAP in GCC hospitals was 217% higher than NHSN hospitals and 69% lower than INICC hospitals. Conclusions The risk of VAP in ICU patients in GCC Countries is higher than pooled U.S. VAP rates but lower than pooled rates from developing Countries participating in the INICC.

economic assessment of the development of co 2 direct reduction technologies in long term climate strategies of the Gulf Countries
Climatic Change, 2021Co-Authors: Alain Haurie, Frederic Louis Francois Babonneau, Ahmed Badran, Maroua Benlahrech, Maxime Schenckery, Marc VielleAbstract:This paper proposes an assessment of long-term climate strategies for oil- and gas-producing Countries—in particular, the Gulf Cooperation Council (GCC) member states—as regards the Paris Agreement goal of limiting the increase of surface air temperature to 2°C by the end of the twenty-first century. The study evaluates the possible role of carbon dioxide removal (CDR) technologies under an international emissions trading market as a way to mitigate welfare losses. To model the strategic context, one assumes that a global cumulative emissions budget will have been allocated among different coalitions of Countries—the GCC being one of them—and the existence of an international emissions trading market. A meta-game model is proposed in which deployment of CDR technologies as well as supply of emission rights are strategic variables and the payoffs are obtained from simulations of a general equilibrium model. The results of the simulations indicate that oil and gas producing Countries and especially the GCC Countries face a significant welfare loss risk, due to “unburnable oil” if a worldwide climate regime as recommended by the Paris Agreement is put in place. The development of CDR technologies, in particular direct air capture (DAC) alleviates somewhat this risk and offers these Countries a new opportunity for exploiting their gas reserves and the carbon storage capacity offered by depleted oil and gas reservoirs.

Water management in the Arabian Gulf region and a partial solution to water shortages
Developments in Water Science, 2003Co-Authors: A.e.m. NairnAbstract:Abstract Even with the most stringent conservation measures on water use—agriculturally, domestically and commercially—there remains a deficit in all the Gulf Countries. The most likely solution to overcome the deficit at the present time is the vastly increased production of desalinated water. Water management policies must be developed nationally to co-ordinate production, distribution and use with the necessary legislative background to deal with potential social, economic issues which can arise out of decisions on the distribution, allocation and charging for water. One by-product of the hydrocarbons used as the energy source for desalination is the release of pollutants, largely carbon dioxide to the atmosphere. However the accession to significant volumes of pollutant gases runs contrary to the terms of the Kyoto accord. This can be avoided by use of solar energy as an alternate energy source. Of the techniques currently available, wind power has the greatest potential, and has been proven in the western US as well as on the plains of Northern Europe. It offers possibilities for both large and small scale operating units.
