BACKGROUND Gastrointestinal bleeding(GIB)is a serious health problem worldwide,particularly during childhood.This can be an alarming sign of an underlying disease.Gastrointestinal endoscopy(GIE)is a safe method for the diagnosis and treatment of GIB in most cases.AIM To determine the incidence,clinical presentation,and outcomes of GIB in children in Bahrain over the last two decades.METHODS This was a retrospective cohort review of the medical records of children with GIB who underwent endoscopic procedures in the Pediatric Department at Salmaniya Medical Complex,Bahrain,between 1995 and 2022.Demographic data,clinical presentation,endoscopic findings,and clinical outcomes were recorded.GIB was classified into upper(UGIB)and lower(LGIB)GIB according to the site of bleeding.These were compared with respect to patients’sex,age,and nationality using the Fisher’s exact,Pearson’sχ2,or the Mann-Whitney U tests.RESULTS A total of 250 patients were included in this study.The median incidence was 2.6/100000 per year(interquartile range,1.4-3.7)with a significantly increasing trend over the last two decades (P < 0.0001). Most patients were males (n = 144, 57.6%). Themedian age at diagnosis was 9 years (5-11). Ninety-eight (39.2%) patients required upper GIEalone, 41 (16.4%) required colonoscopy alone, and 111 (44.4%) required both. LGIB was morefrequent (n = 151, 60.4%) than UGIB (n = 119, 47.6%). There were no significant differences in sex (P = 0.710), age (P = 0.185), or nationality (P = 0.525) between the two groups. Abnormalendoscopic findings were detected in 226 (90.4%) patients. The common cause of LGIB was inflammatorybowel disease (IBD) (n = 77, 30.8%). The common cause of UGIB was gastritis (n = 70, 28%).IBD and undetermined cause for bleeding were higher in the 10-18 years group (P = 0.026 and P =0.017, respectively). Intestinal nodular lymphoid hyperplasia, foreign body ingestion, andesophageal varices were more common in the 0-4 years group (P = 0.034, P < 0.0001, and P = 0.029,respectively). Ten (4%) patients underwent one or more therapeutic interventions. The medianfollow-up period was two years (0.5-3). No mortality was reported in this study.CONCLUSIONGIB in children is an alarming condition, whose significance is increasing. LGIB, commonly due toIBD, was more common than UGIB, commonly due to gastritis. 展开更多

BACKGROUND Children like to discover their environment by putting substances in their mouths.This behavior puts them at risk of accidentally ingesting foreign bodies(FBs)or harmful materials,which can cause serious morbidities.AIM To study the clinical characteristics,diagnosis,complications,management,and outcomes of accidental ingestion of FBs,caustics,and medications in children.METHODS We conducted a retrospective cohort study of all children admitted for accidental ingestion to the Department of Pediatrics,Salmaniya Medical Complex,Bahrain,between 2011 and 2021.Demographic data,type of FB/harmful material ingested,and investigations used for diagnosis and management were recorded.The patients were divided into three groups based on the type of ingested material(FBs,caustics,and medications).The three groups were compared based on patient demographics,socioeconomic status(SES),symptoms,ingestion scenario,endoscopic and surgical complications,management,and outcomes.The FB anatomical location was categorized as the esophagus,stomach,and bowel and compared with respect to symptoms.The Fisher’s exact,Pearson’s χ^(2),Mann-Whitney U,and Kruskal-Wallis tests were used for comparison.RESULTS A total of 161 accidental ingestion episodes were documented in 153 children.Most children were boys(n=85,55.6%),with a median age of 2.8(interquartile range:1.8-4.4)years.Most participants ingested FBs(n=108,70.6%),31(20.3%)ingested caustics,and the remaining 14(9.2%)ingested medications.Patients with caustic ingestion were younger at the time of presentation(P<0.001)and were more symptomatic(n=26/31,89.7%)than those who ingested medications(n=8/14,57.1%)or FBs(n=52/108,48.6%)(P<0.001).The caustic group had more vomiting(P<0.001)and coughing(P=0.029)than the other groups.Most FB ingestions were asymptomatic(n=55/108,51.4%).In terms of FB location,most esophageal FBs were symptomatic(n=14/16,87.5%),whereas most gastric(n=34/56,60.7%)and intestinal FBs(n=19/32,59.4%)were asymptomatic(P=0.002).Battery ingestion was the most common(n=49,32%).Unsafe toys were the main source of batteries(n=22/43,51.2%).Most episodes occurred while playing(n=49/131,37.4%)or when they were unwitnessed(n=78,57.4%).FBs were ingested more while playing(P<0.001),caustic ingestion was mainly due to unsafe storage(P<0.001),and medication ingestion was mostly due to a missing object(P<0.001).Girls ingested more jewelry items than boys(P=0.006).The stomach was the common location of FB lodgment,both radiologically(n=54/123,43.9%)and endoscopically(n=31/91,34%).Of 107/108(99.1%)patients with FB ingestion,spontaneous passage was noted in 54(35.5%),endoscopic removal in 46(30.3%),laparotomy in 5(3.3%)after magnet ingestion,and direct laryngoscopy in 2(1.3%).Pharmacological therapy was required for 105(70.9%)patients;79/105(75.2%)in the FB group,22/29(75.9%)in the caustic group,and 4/14(28.8%)in the medication group(P=0.001).Omeprazole was the commonly used(n=58;37.9%)and was used more in the caustic group(n=19/28,67.9%)than in the other groups(P=0.001).Endoscopic and surgical complications were detected in 39/148(26.4%)patients.The caustic group had more complications than the other groups(P=0.036).Gastrointestinal perforation developed in the FB group only(n=5,3.4%)and was more with magnet ingestion(n=4)than with other FBs(P<0.001).In patients with FB ingestion,patients aged<1 year(P=0.042),those with middle or low SES(P=0.028),and those with more symptoms at presentation(P=0.027)had more complications.Patients with complications had longer hospital stays(P<0.001)than those without.CONCLUSION Accidental ingestion in children is a serious condition.Symptomatic infants from middle or low SES families have the highest morbidity.Prevention through parental education and government legislation is crucial. 展开更多

BACKGROUND Ventilator-associated pneumonia(VAP)is defined as pneumonia that occurs two calendar days following endotracheal intubation or after that.It is the most common infection encountered among intubated patients.VAP incidence showed wide variability between countries.AIM To define the VAP incidence in the intensive care unit(ICU)in the central gove-rnment hospital in Bahrain and review the risk factors and the predominant bacterial pathogens with their antimicrobial susceptibility pattern.METHODS The research was a prospective cross-sectional observational study over six months from November 2019 to June 2020.It included adult and adolescent patients(>14 years old)admitted to the ICU and required intubation and mechanical ventilation.VAP was diagnosed when it occurred after 48 h after endotracheal intubation using the clinical pulmonary infection score,which considers the clinical,laboratory,microbiological,and radiographic evidence.RESULTS The total number of adult patients admitted to the ICU who required intubation and mechanical ventilation during the study period was 155.Forty-six patients developed VAP during their ICU stay(29.7%).The calculated VAP rate was 22.14 events per 1000 ventilator days during the study period,with a mean age of 52 years±20.Most VAP cases had late-onset VAP with a mean number of ICU days before the development of VAP of 9.96±6.55.Gram-negative contributed to most VAP cases in our unit,with multidrug-resistant Acinetobacter being the most identified pathogen.CONCLUSION The reported VAP rate in our ICU was relatively high compared to the international benchmark,which should trigger a vital action plan for reinforcing the implementation of the VAP prevention bundle. 展开更多

The study aims to focus upon the association between the auditors and companies by indicating how this association affects the quality of audit and auditor independence in a developing country (the case of Bahrain). To achieve these objectives, a questionnaire was developed and distributed to respondents from audit firms in Bahrain. Descriptive statistics were used to analyse the influence of auditor-client association upon quality of audit and auditor independence and how audit quality and auditor independence are improved was also explored in the study. The results show that all the questions (1-8) in the questionnaire impair both audit quality and auditor independence with the means ranging from 3.6000 to 4.0364 with an average mean of 3.7212. According to the measurement scale, any item with a mean of 3.50 or more is acceptable, and since all the influences are above 3.50, they are all acceptable. Regarding how auditor-client relationship (or long tenured auditor) would improve both quality of audit and auditor independence, the results show that all the questions (9-17) would improve both audit quality and auditor independence with the means ranging from 3.6364 to 4.0727 with an average of 3.8646, which are acceptable. These results confirm statistically that there is a significant relationship between the auditor long-term tenure and audit quality and auditor independence, so the null hypothesis (H0) is rejected and the alternative hypothesis is accepted. Simple regression analysis is employed to test the hypothesis of the study and its significance. The results show that (H0) hypothesis is not significant. Therefore, the alternative hypothesis (H1) is significant at p 〈 0.005, which means that there are differences in viewpoints among respondents and the p-value obtained is 0.044 which is less than the significant value of p 〈 0.05. These results confirm the hypothesis that a significant relationship exists between the auditor long-term tenure and quality of audit and auditor independence. 展开更多

The objectives of this study are: (1) to explore current audit appointment practices by audit firms in Bahrain; (2) to look into the opinions of audit firms in Bahrain on potential effects provided by implementing mandatory audit firm rotation (audit quality); and (3) to investigate audit firms' views in implementing mandatory audit firm rotation in Bahrain. To achieve these objectives, a questionnaire was developed and distributed to respondents that consist of all auditors working in audit firms in Bahrain. The findings indicated that there is a significant relationship between mandatory audit firm rotation and quality of audit. The study also indicated that longer partner tenure makes the auditor's performance lack the quality in the auditing process. The average mean for all questions of the hypothesis together is 2.73 with average standard deviation of 0.94 which is less than half of the mean. This means that there is no dispersion among respondents about the questions of the hypothesis. Also, the analysis shows that the t-value is 29.922, which is greater than the table critical value of t (1.66), and the p-value obtained is 0.000 which is less than the value of significance at p 〈 0.05. These results confirm statistically that there is a significant relationship, so the null hypothesis is rejected and the alternative hypothesis is accepted. 展开更多

Municipal Solid Waste (MSW) becomes a point of focus globally due to its harmful effects on the environment and human health if it is not managed properly. MSW was proved globally to be used as a resource, and it has a major opportunity in the realm of conversion technologies. Accordingly, this study aims to explore the enablers and barriers to six different MSW management (MSWM) technologies adopted in the Kingdom of Bahrain, in order to ensure the successful adoption of these technologies that are Anaerobic Digestion (AD), Incineration, Pyrolysis, Gasification, Composting and Refused Derived Fuel (RDF). This study provides sufficient information to the decision and policy-makers for the processes of selection and adoption of the MSWM technologies in Bahrain, using a qualitative approach “mainly semi-structured interviews” with experts and then Thematic Analysis using nvivo12 software. The results show that the main themes that enablers and barriers fall under are: political (e.g. national waste management strategy), technical (e.g. segregation at source), managerial (e.g. capacity building), social (e.g. public awareness), economic (e.g. incentives to investment) and environmental (e.g. air quality). This study concluded that in order to succeed in the MSWM technologies adoption, the resulted barriers should be overcome. Furthermore, Incineration was recommended as the best solution to manage MSW which has the least barriers and most enablers in Bahrain as per the experts. 展开更多

Marine environment of the Arabian Gulf is naturally stressed due to marked fluctuations in sea temperatures and high salinities. Anthropogenically induced stresses including waste water discharges from desalination plants could pose additional threats to the coastal and marine ecosystems in the Arabian Gulf. Macrobenthic assemblages in the proximity of two major desalination plants that use Multi-Stage Flash (MSF) and brackish water Reverse Osmosis (RO) technologies in Bahrain were investigated. Reduced levels of biodiversity and abundance were recorded in sampling stations adjacent to the outlet of MSF reflecting severe impacts on macrobenthic assemblages caused by brine effluents that associated with high temperatures, salinities, and a range of chemical and heavy metal pollutants. Although localized severe impacts on macrobenthic assemblages were detected, collective discharges of desalination effluents, may synergistically contribute to the degradation of the naturally stressed marine ecosystems and natural resources in the Arabian Gulf. 展开更多

There is a growing demand for high building performance,providing better energy efficiency as well as high standard living and workplace. Intelligent Buildings (IBs) will meet the needs of sustainable development in built environment. The Kingdom of Bahrain's construction industry has grown significantly in past years to support economic growth,other business sectors,and the aim to be one of the world's major financial centres. This paper aims at investigating current issues regarding intelligent buildings in the Kingdom of Bahrain. Case studies of three buildings,which are Bahrain Financial Harbour (BFH),Bahrain World Trade Centre (BWTC) Project and the Bahrain City Centre (BCC) Shopping Mall,have been carried out via structured observation,interview and questionnaire survey in Bahrain in 2007. Through this study,we conclude that the pace of construction in Bahrain and the Middle East is such that there are lots of scopes for IBs to develop further,both from the perspective of the number of IBs being built and also the sophistication of their specifications. 展开更多

This study examines the Granger causality relationships between economic growth,energy consumption and emissions,from 1980 to 2007 in Bahrain,controlling for capital and urban population using Toda and Yamamoto's approach.It was found that there is unilateral causality which runs from urban population,economic growth,capital and energy consumption to environment.Further,we found strong support for causality running from economic growth to energy consumption,emissions and capital.The existence of these linkages suggests that the government of Bahrain may pursue energy efficiency strategies and carbon emissions reduction policy in the long run without impeding economic growth.Additionally,the long run pursuit of high economic growth given sustained increases in energy efficiency may also reduce CO_2 emissions intensity per unit of her GDP. 展开更多

In Bahrain, like the other Gulf Cooperation Council (GCC) countries, desalination is inevitable to meet the escalating municipal water demands. However, desalination is associated with many environmental effects, which need to be minimized to their lowest possible limits. One of the major environmental concerns of desalination in the Arabian Gulf region is the local and regional effects of the outfall areas on the marine environment. In this study, the outfall area of a government-owned MSF desalination plant is characterized in terms of temperature and salinity. The spatial extent of the plume of the desalination plant’s effluent is mapped by a field survey conducted during the winter season around the plant’s outfall area at 25 cm and 1 m below the water surface and at low and high tide. The results of the characterization indicated that the temperature of the brine discharged to the outfall was 37°C, higher than the ambient seawater temperature by 16.5°C at high tide and 17.5°C at low tide, and that the extent of the mixing zone area was found at about 260 m and 1 km from the outfall point at high tide and low tide, respectively. The results also showed that brine thermal discharge is not in compliance with the standard limits (<3°C from ambient within 100 m of shoreline) both at high and low tides with differences reaching more than 10°C. In terms of salinity, the brine discharged salinity was 56.2 parts per trillion (ppt) compared to an ambient seawater salinity of 43.2 ppt. The maximum salinity measured near the outfall point was 56 ppt at low tide and 51 ppt at high tide, both at 1 m below the surface water column. It is found that the current design structure consisting of two jetties to isolate the desalination plant outfall area from its surroundings is not environmentally sound, as the current surface/inter-tidal outfall location is susceptible to significant increases in salinity and temperature around the outfall area due to the limited flushing it experiences. Therefore, the current design of the outfall area needs to be reviewed to ensure meeting brine discharge regulations and mitigate its impact on the surrounding marine area. The spatial extent of the brine plume can be minimized by building a discharge area further offshore at a sub-tidal location where turbulent flow exists to minimize the spatial extent and intensity of the brine plume. It is recommended that this characterization be extended to all desalination plants in Bahrain, and a regular monitoring program, which should also include selected biological communities and organisms of ecological relevance, be established around the desalination plants outfall areas. 展开更多

Municipal Solid Waste (MSW) generation is growing rapidly as compared to the rate of urbanization. Household waste management is considered a highly challenging task for Bahrain’s policy-makers, urban planners and municipalities due to rising population, burgeoning growth rate of waste generation, limited availability of land and scarce waste disposal sites. Public awareness represents a key enabler in order to succeed any sustainable waste management practice in the country. The survey aimed at gauging public awareness about household waste management in Muharraq Governorate and explored if there are any correlations between educational level, gender, occupation and age and area of living with the level of public awareness as well as its three components: knowledge, attitude and behaviour of the people in Muharraq Governorate. The results indicated the total awareness is significantly different across different age levels and nationality. Moreover, it shows a high public awareness toward household waste management among people in Muharraq Governorate, which indicated that the society is aware and has the basics to build on in terms of sustainable waste management practices and technologies adoption, which may help overcome the possible social barrier represented by low public awareness. 展开更多

Environmental Impact Assessment (EIA) was formally adopted as a measure to protect the environment in Bahrain in 1998. A decade after its implementation, this paper evaluates the current EIA system in Bahrain using a set of criteria. The evaluation was based on review of literature, investigation of legislative and administrative framework and interviews with EIA practitioners. Several measures are required to further strengthen the EIA system in Bahrain including amending EIA laws to include whole aspects of EIA process, developing comprehensive guidelines on procedural EIA, increasing public participation, improving capacity building and integrating environmental concerns to higher-level policy making through existing national environmental strategies. Findings of this study could contribute to wider international experience of EIA performance in developing countries. 展开更多

Business analysts worldwide use the standard theories and tools of macroeconomics and finance to determine the investment, trade or production possibilities in foreign markets. These evaluations are generally supported by three sources: estimations of using country-specific macroeconomic data on which they can determine patterns of growth, inflation, unemployment, productivity, income per capita, etc.; timely data on current conditions and developments in production, income and spending; and institutional information on policy makers, business practices and financial markets. This paper focuses on the first two where we examine the publically available macroeconomic data for the Kingdom of Bahrain to determine their reliability. Among our findings are: (1) creating a reliable data base of macroeconomic data is difficult due to data revision and incomplete data gathering; (2) the movement of standard macro-variables is often unusual, leading one to question further the reliability of the data; (3) based on available data it appears that the growth in Bahrain has been driven almost solely by an increase in the number of people working, with little to no apparent rise in productivity; and (4) the growth of GDP will eventually be constrained by physical limits on population growth, and can be improved only if ways can be found to increase the productivity of the workforce. 展开更多

This paper will present several passive-cooling technologies and design features that can be adopted to reduce building heat gain without the need of excess energy consumption. A typical residential unit will be selected as case study and a three basic passive cooling strategies were selected to enhance the building envelop, as well as using appropriate shading devices and green roofing system that prove to be a good environment quality improver. IES energy simulation software will be used to evaluate the performance of the building. The study revealed a number of significant findings in reducing the energy consumption and enhancing the tenants' thermal comfort. American Society of Heating Refrigerating and Airconditioning Engineer (ASHRAE) standards specially via improving the performance of building envelop because it is the interface between internal and external environment. Moreover, improving the building envelope has recorded that overall energy and chiller energy consumption can be reduced up to 10.8% and 21.6% respectively, Therefore, it is anticipated that further reductions can be achieved via applying more passive cooling strategies. Finally, it could argue that the results of this paper will not only be applicable to Bahrain but also many countries that have similar climatic and environmental context. 展开更多

Monitoring and assessment of agricultural land degradation is of vital importance for better land and water management planning and reclamation. It requires setting baseline information and basic analysis at specific time and space. About 33 geo-referenced soil sampling spots were selected in two agricultural production locations in the Kingdom of Bahrain to assess the status and preliminary causes of land degradation. Soil samples were taken from 13 sites in Diraz location while 19 samples were taken from Budayyi location. The samples were taken to 90 cm depth at 30 cm intervals. Standard procedures were followed to determine soil physiochemical properties. In addition, field observations on farm condition, distance from the sea, method of irrigation and irrigation water source were taken. Some of the soil samples were deliberately taken from outside the irrigated basins among trees compared with samples taken from inside the actively growing area for comparison. The results indicated that the salinity level was significantly (P 〈 0.001) higher at the 0-30 cm soil depth compared with 30-60 cm or 60-90 cm depths in both locations. The distance from the sea did not show clear correlation with surface soil salinity in Budayyi area compared with Diraz. Both locations showed significantly higher salinity levels on samples taken outside the actively growing areas compared with those taken from within. The effect is more prominent at the 0-30 cm depth. The observed variability on salinity levels may be attributed to farm management practices and deteriorating quality of ground water. Thus, agricultural land degradation in Bahrain cannot be attributed to ground water deterioration alone. The use of tertiary treated sewage water (TSE) may ease the pressure on ground water, but the pH of the TSE should be carefully monitored and managed with proper studies on leaching requirements to avoid further salinity complications. 展开更多

The GCC countries have been experiencing an accelerated socio-economic development process since the 1970s,resulting in rapid demographic and urbanization growth and associated with rapidly increasing municipal water demands.To meet these demands’quantity and quality,the GCC countries resorted to desalination.Currently,the GCC countries collectively possess the largest desalination capacity in the world(~45%),and based on the current urbanization trends,it is expected that current rates in desalination capacity growth will continue in the future.However,desalination has a number of environmental externalities on the marine,and their severity will depend on various factors(i.e.,site-specific).The objective of the present study is to investigate the impacts of the brine water discharged by Al-Dur RO desalination plant on the coastal infauna benthic species composition in the east coast of Bahrain.Sediment samples were collected from 10 locations selected at different distances from the discharge outlet.The species composition of infauna was investigated using univariate analysis and multivariate analysis.The results showed an extreme elevation in temperature(>38℃)and hypersaline waters(>55‰)at locations nearby the discharge outlet,and also at bottom waters of depths more than 3 m during the high and low tide cycles in both seasons with exceptional levels in summer.Four main groups of benthic infauna identified are represented by Polychaeta(12 taxa),Bivalves(4 taxa),Gastropod(2 taxa),and Amphipod(3 taxa)including 256 specimens.The univariate analysis indicated spatial variations in infauna species composition where the lower diversity indices were found at locations close to the discharge outlet and at Station 5 where noticeable vertical differences were observed indicating exceptional elevation of hypersaline waters with lesser extent of temperature at bottom layer.However,the highest species diversity indices characterized the most offshore stations.The infauna species composition found to be related to the water quality particularly salinity in the outlet vicinity rather than the bottom texture.Polychaeta could be considered as the most useful bio-indicator to reveal any contamination from desalination brine discharge,due to their sensitivity and their capability to adopt to any environmental alteration. 展开更多

The adoption and use of social media has played a major role in the changes in journalists’ work. The use of these new means has become indispensable to the daily tasks and work of journalists in most news organizations. It is no longer possible to bypass these means when it comes to searching for information and news, or in production, publishing, distribution and marketing, or even in interaction with the public. The characteristics of ease, speed, immediacy, interactivity, and being free of charge that characterize them, have made them a useful technological tool, which is influential and necessary not only for the future of the journalist’s career but also for the future of the news organization itself. With the growing number of users of social media around the world, journalists and news organizations have found additional access, more important than previous channels, to access additional sources that help them market and interact with their work in a new dynamic environment completely different from previous communication models, and put audience activity at the forefront. In this study, which is part of the Technology Acceptance Model (TAM), the author tries to understand and analyze the factors of adoption and use of social media as a new technological tool by Bahraini journalists and to identify their new role in the changes in journalism. In addition, the study attempts to examine the implications in relation to the future of the press profession and the economic model of the news organization. The results showed a clear adoption and an increased use of social media by journalists, who consider it a key element in the development of journalism, and an inevitable strategic choice for the future of the news organization. They also expressed their full awareness of the problems surrounding the issue of precision and credibility of news accessed through social media. 展开更多
