[Ab] Resumo:BACKGROUND: Effective clinical teaching is crucially important for the future of patient care. Robust clinical training therefore is essential to produce physicians capable of delivering high quality health care. Tools used to evaluate medical faculty teaching qualities should be reliable and valid. This study investigates the psychometric properties of modification of the System for Evaluation of Teaching Qualities (SETQ) instrument in the clinical years of undergraduate medical education. METHODS: This cross-sectional multicenter study was conducted in four teaching hospitals in the Kingdom of Bahrain. Two-hundred ninety-eight medical students were invited to evaluate 105 clinical teachers using the SETQ instrument between January 2015 and March 2015. Questionnaire feasibility was analyzed using average time required to complete the form and the number of raters required to produce reliable results. Instrument reliability (stability) was assessed by calculating the Cronbach's alpha coefficient for the total scale and for each sub-scale (factor). To provide evidence of construct validity, an exploratory factor analysis was conducted to identify which items on the survey belonged together, which were then grouped as factors. RESULTS: One-hundred twenty-five medical students completed 1161 evaluations of 105 clinical teachers. The response rates were 42% for student evaluations and 57% for clinical teacher self-evaluations. The factor analysis showed that the questionnaire was composed of six factors, explaining 76.7% of the total variance. Cronbach's alpha was 0.94 or higher for the six factors in the student survey; for the clinical teacher survey, Cronbach's alpha was 0.88. In both instruments, the item-total correlation was above 0.40 for all items within their respective scales. CONCLUSION: Our modified SETQ questionnaire was found to be both reliable and valid, and was implemented successfully across various departments and specialties in different hospitals in the Kingdom of Bahrain.

[Ab] Resumo:A study of the external background radiation in areas affected by NORM generated by oil and gas industrial activities has been performed in the Kingdom of Bahrain. In this framework, two experimental residential areas, Awali and Riffa Views, were selected due to the presence of extensive oil and gas exploration and transportation. Additionally, two control residential areas, Isa Town and Al-Budaiya Village, were selected as they lack any industrial activities that would disrupt the radiation profile. The radiation dose rates were measured using Colibri Very Low Dose radiation survey meter with a built-in GPS. A total of 317 dose rates with their GPS coordinates were acquired. The lowest dose rate was 0.02 µSv/h acquired in Isa Town while the highest dose rate was 0.37 µSv/h acquired in Awali. Since there were no studies performed in the Kingdom to measure the average background radiation, the average external background radiation calculated from the control areas was used in this study which is 0.75 ± 0.31 mSv/y. The measured mean annual equivalent doses above the background radiation levels in Isa Town, Al-Budaiya, Riffa Views and Awali were -0.05 ± 0.05 mSv/y, 0.04 ± 0.04 mSv/y, 0.62 ± 0.13 mSv/y and 1.32 ± 0.35 mSv/y respectively. In other words, the radiation measurements were notably higher in the experimental areas. This was particularly true in south and southwestern Awali where the annual equivalent dose in some areas reached 2.49 mSv/y above average background levels. The geological constituent of the earth crust could be one source that contribute to overall background radiation. However, presence of NORM generated by extensive oil and gas operations and transportation is stronger justification for the higher radiation readings in the experimental areas than geological characteristic factor. Such high radiation values were found only near oil and gas installations and not in other locations of the same areas.

[Ab] Resumo:INTRODUCTION: Bahrain has high prevalence rates of sickle cell and thalassemia in the population. This study reports the frequencies and phenotypic characteristics of α- and/or ß-thalassemia associated with sickle-cell disease (SCD) in a tertiary care hospital. METHODS: Adult SCD patients (n = 200) were screened for the common α- and ß-thalassemia alleles prevalent in the region using molecular techniques. Results of CBC, hemoglobin analysis, and average annual frequencies of severe pain episodes and numbers of transfused red cell units were documented. RESULTS: Patients were grouped on the basis of molecular studies as sickle-cell anemia (SS, n = 131), SS/α-thalassemia with three normal genes (n = 27), SS/α-thalassemia with two normal genes (n = 11), sickle-ß-thalassemia (Sß, n = 23), and Sß with co-inherited α-thalassemia (n = 8). Identified α-thalassemia determinants were -α (n = 52), -α (n = 4), α α (n = 1), and α α (n = 1). All ß-thalassemia alleles were ß defects. Sickle-thalassemia association resulted in higher hemoglobin, hematocrit, and erythrocyte counts with reduced MCV and reticulocytes. Significant clinical associations were as follows: increased severe pain frequency with α-thalassemia (three-gene group); red cell transfusion with ß-thalassemia alleles and female gender. CONCLUSION: One-third of patients with SCD co-inherited α- and/or ß-thalassemia alleles and these associations explained some of the observed phenotypic variability. A low prevalence of nondeletion α-thalassemia alleles was observed in these patients. The most significant disease amelioration occurred in SCD associated with two α-thalassemia alleles.

[Ab] Resumo:Limited data are available on the epidemiology, clinical manifestations and outcomes of patients with invasive aspergillosis in Bahrain. This study was conducted retrospectively to determine the epidemiology of invasive aspergillosis and its risk factors, clinical presentation, underlying conditions, and outcomes over the past five years in a major hospital. The medical records of patients with positive Aspergillus cultures admitted to a major tertiary care hospital in Bahrain during 2009-2013 were reviewed. Cases were classified according to (1) the European Organization for the Research and Treatment of Cancer/Mycoses Study Group (MSG) criteria (proven, probable, possible IA or not classifiable) and (2) "validated" criteria to distinguish Aspergillus colonization from IA (putative or proven IA). Demographic, microbiologic and diagnostic data were collected, and outcomes were recorded. A total of 60 patients were included, of whom 44 were colonized (73.3%), and 16 had probable IA (26.7%); no proven or possible IA cases were identified according to the EORTC/Mycoses Study Group (MSG) criteria. In comparison, with the alternative "validated" criteria, 32 were colonized (53.3%), 28 had putative IA (46.7%), and none had proven IA (0%). The lung was the most common site of infection, and Aspergillus fumigatus was the most commonly isolated species (53%). Mortality was 25% among colonized patients, 44% in probable cases and 32% in those with putative IA. All patients were immunocompromised or had one or more predisposing factors. Independent risk factors for death among patients with IA included older age, history of mechanical ventilation, renal replacement therapy and higher sequential organ failure assessment scores at diagnosis.

[Ab] Resumo:OBJECTIVE: The aim of this study was to investigate the dietary patterns and sedentary behaviors among university students in Bahrain. MATERIALS AND METHODS: A cross-sectional study was carried out with students of the College of Health Sciences in Bahrain using a self-reported questionnaire. All the students enrolled in this college were included in this study (642 students; 90 males and 552 females). The mean age of the sample was 20.1±2.0 years. A pre-tested questionnaire was used to collect information on the students' breakfast intake, snacking, food frequency intake, and sedentary habits. RESULTS: More than 50% of the students did not consume breakfast on a daily basis. A statistically significant difference (p<0.003) was found between males (19%) and females (35%) in relation to the intake of an afternoon snack. There were no significant gender differences regarding frequency of food intake, except for carbonated beverages (p<0.001) and nuts (p<0.047) consumption. Females were more likely than males to spend time watching television, use the Internet, use a mobile phone and sleep; however, the only significant difference found was for Internet use (p<0.003). Being physically active on a daily basis was more prevalent among males (41.6%) than females (16%) (p<0.001). Females (42.9%) were more prone to sleep for less time (<7 h) than males (34.4%)(p<0.08). CONCLUSION: The findings indicated that a high percentage of health science students in Bahrain had unhealthy dietary habits and sedentary behaviors. Thus, an intervention program to promote healthy dietary patterns and lifestyle habits among university students is highly recommended.

[Ab] Resumo:This study aimed to estimate the frequency of the SNPs (+45T>G and +276G>T) genotypes and investigate the association between the two SNPs and adiponectin concentration, metabolic parameters and risk of T2DM in the Bahraini population. We genotyped the two ADIPOQ SNPs in 140 unrelated T2DM patients and 66 nondiabetic controls using the polymerase chain reaction-restriction fragment length polymorphism assay. Lipid profile was measured by enzymatic methods. Total serum adiponectin levels were measured by immunoassay. T2DM patients had reduced adiponectin levels compared with controls. +45T>G was more prevalent in patients than controls. The rare G allele of +45T>G occurred more frequently than the common T allele in T2DM patients compared with controls, and was associated with lower serum adiponectin levels. There was no significant difference in allele and genotype frequencies of +276G>T between type T2DM patients and controls. There was no association between both SNPs and metabolic parameters.

[Ab] Resumo:Type 2 diabetes mellitus is prevalent especially in Gulf countries and poses serious long-term risks to patients. A multifaceted treatment approach can include nutritional supplements with antioxidant properties such as 5-aminolevulinic acid (5-ALA) with sodium ferrous citrate (SFC). This prospective, randomized, single-blind, placebo-controlled, dose escalating pilot clinical trial assessed the safety of 5-ALA with SFC at doses up to 200 mg 5-ALA/229.42 mg SFC per day in patients living in Bahrain with type 2 diabetes mellitus that was uncontrolled despite the use of one or more antidiabetic drugs. Fifty-three patients ( = 53) from 3 sites at one center were enrolled by Dr. Feryal (Site #01), Dr. Hesham (Site #02), and Dr. Waleed (Site #03) ( = 35, 5-ALA-SFC; = 18, placebo). There was no significant difference in incidence of adverse events reported, and the most frequent events reported were gastrointestinal in nature, consistent with the known safety profile of 5-ALA in patients with diabetes. No significant changes in laboratory values and no difference in hypoglycemia between patients receiving 5-ALA and placebo were noted. Overall, the current results support that use of 5-ALA-SFC up to 200 mg per day taken as 2 divided doses is safe in patients taking concomitant oral antidiabetic medications and may offer benefits in the diabetic population. This trial is registered with ClinicalTrials.gov NCT02481141.

[Ab] Resumo:INTRODUCTION: HIV/AIDS is one of the major health problems worldwide. Despite the low prevalence of HIV in Bahrain, educational and awareness programs remain highly important in controlling and preventing the spread of the disease. This study aimed to assess the public's knowledge, risk perceptions, and attitudes towards HIV/AIDS in Bahrain. METHODOLOGY: A self-administered questionnaire-based survey was administered to and completed by 1,038 Bahraini adults. RESULTS: Although the average general awareness among participants was good (63%), some misconceptions and erroneous beliefs were common, including knowledge of mode of transmission and high risk groups. Participants' attitudes towards HIV/AIDS patients varied but were mostly negative; 60% of respondents agreed to isolating HIV/AIDS patients in workplaces and schools, and 52.4% of them thought that HIV is a divine punishment. The vast majority of the participants (84.4%) believed in the role of religion in limiting the spread of the disease. Though the local media was the least utilized source of information, the general opinion of the participants about the role of Bahraini government agencies and organizations in combating HIV/AIDS was positive. CONCLUSIONS: Though the Bahraini public had good knowledge about HIV/AIDS, there were misconceptions that need to be addressed. A major finding of this study was the negative attitudes towards HIV/AIDS patients. To have successful HIV control programs, negative attitudes towards HIV patients and the disease should be minimized. Existing and newly proposed health education and awareness program in Bahrain should address the issue of negative attitudes towards HIV/AIDS observed in this study.

[Ab] Resumo:Meningitis is among the 10 commonest infectious causes of death worldwide. This retrospective analysis of reported cases of meningitis in Bahrain aimed to assess the trend in the incidence of bacterial meningitis from 1990 to 2013, before and after the introduction of new vaccines. Of 1455 reported cases of meningitis during the study period 73.1% were viral and 26.9% were bacterial etiology (tuberculous meningitis 8.3%; Streptococcus pneumoniae 4.9%, Haemophilus influenzae 3.6% and Neisseria meningitidis 1.7%). There was a peak of meningitis cases in 1995-1996. The incidence of meningitis due to H. influenzae and N. meningitidis showed a marked reduction after the introduction of the corresponding vaccines in 1998 and 2001 respectively, and S. pneumoniae became the predominant organism after Mycobacterium tuberculosis. The changing trend in the etiology of bacterial meningitis points to the need to study vaccination programme modifications, such as pneumococcal vaccine for the adult population, especially high-risk groups.

[Ab] Resumo:CONTEXT: In problem-based learning (PBL), students construct concept maps that integrate different concepts related to the PBL case and are guided by the learning needs generated in small-group tutorials. Although an instrument to measure students' concept maps in PBL programmes has been developed, the psychometric properties of this instrument have not yet been assessed. OBJECTIVES: This study evaluated the generalisability of and sources of variance in medical students' concept map assessment scores in a PBL context. METHODS: Medical students (Year 4, n = 116) were asked to construct three integrated concept maps in which the content domain of each map was to be focused on a PBL clinical case. Concept maps were independently evaluated by four raters based on five criteria: valid selection of concepts; hierarchical arrangement of concepts; degree of integration; relationship to the context of the problem, and degree of student creativity. Generalisability theory was used to compute the reliability of the concept map scores. RESULTS: The dependability coefficient, which indicates the reliability of scores across the measured facets for making absolute decisions, was 0.814. Students' concept map scores (universe scores) accounted for the largest proportion of total variance (47%) across all score comparisons. Rater differences accounted for 10% of total variance, and the student × rater interaction accounted for 25% of total variance. The variance attributable to differences in the content domain of the maps was negligible (2%). The remaining 16% of the variance reflected unexplained sources of error. Results from the D study suggested that a dependability level of 0.80 can be achieved by using three raters who each score two concept map domains, or by using five raters who each score only one concept map domain. CONCLUSIONS: This study demonstrated that concept mapping assessment scores of medical students in PBL have high reliability. Results suggested that greater improvements in dependability might be made by increasing the number of raters rather than by increasing the number of concept map domains.
