Objective
The purpose of this study was to assess the use of and satisfaction with the academic-advising and student-support systems available to undergraduate students in the College of Dentistry at the University of Dammam. In addition, the study aimed to also identify factors that explained the help-seeking behavior of students which they used to solve academic issues.Materials and methods
Students enrolled in the five-year Bachelor of Dental Surgery (BDS) program in 2012–13 and 2013–14 first-year students were invited to respond to a self-administered questionnaire.Results
The results showed that 66.2% of students had discussed academic issues with their advisor at least once, with a frequency ranging from zero to six times. Most students reported that their advisors were readily available, listened intently to their needs and questions, and helped them solve their problems. However, only 7.6% of students relied primarily on advisors for help with academic issues, whereas 51% depended first on colleagues and 13.8% did not seek help and relied on themselves. In total, 17.2% of students were very or somewhat satisfied with the academic advising system. Males had lower odds of discussing issues with their advisors, and the odds were higher with advisors who were more available (OR = 0.25 and 3.74, respectively). Alerting students to important dates in the academic calendar significantly increased the odds that a student would depend primarily on academic advisors for advice related to academic issues (OR = 6.53).Conclusions
Few students were satisfied with the academic support system. We need to train advisors to help them develop their skills and knowledge and to enable them to provide the support needed by the students. 相似文献53.

Objectives:
To evaluate the knowledge and behavior of workers at a Saudi airport regarding public health emergency measures applied during Hajj season.Methods:
This study is a cross-sectional study conducted at the Prince Mohammed International Airport in Al-Madinah Al-Munawwarah, Saudi Arabia between August and September 2014. Data were collected by semi-structured questionnaires during personal interviews. Non-random purposive sampling was conducted to target workers at higher risk of acquiring infection from travellers.Results:
One hundred and eighty-six participants were recruited of whom 92.5% were males. The study participants were workers in 8 different sectors. Twenty-six percent of the participants were health workers. Non-health workers were more likely to be concerned on acquiring infection while working at the airport compared with health workers (p=0.023). The most commonly feared disease was Ebola viral disease (EBV) among 30% of health workers, and 47% of non-health workers. Approximately 47% of non-health workers reported no knowledge of the procedures implemented during public health emergencies. The proportion of participants who received public health related training among non-health workers was significantly lower compared with health workers (p<0.00001).Conclusion:
More emphasis should be given to educating airport workers on the potential health threats at the airport. Specific guidelines for public health emergencies at the airport should be established and communicated with airport sectors.Airports are frontier gates where proper public health measures are likely to reduce the possibility of allowing the entrance of communicable disease to a country. According to the World Health Organization (WHO) International Health Regulations mandate WHO member states to ensure that every designated point of entry is equipped with staff and instruments enabling smooth movements of the travellers while maintaining appropriate public health measures.1 Maintaining such regulations is likely to enhance proper travellers’ movement during public health emergencies by reducing possible interference between application of preventive public health measures, and the ability of travellers to access the designated points of entry. Additionally, ensuring the application of public health measures might aid in preventing the occurrence of any public health emergencies. A public health emergency is defined as any situation with health consequences that are likely to overwhelm the community’s routine capability of addressing them. A health situation can be considered as an emergency if there is a risk due to timing, such as facing emerging diseases threats during Hajj season, scale, as with an overwhelming number of causalities, or due to the unpredictability of the situation. Defining the nature of potential public health emergencies is crucial to allow competent development of preparedness plans.2 Having a large number of passengers arriving at a particular point of entry during a limited time is a burden on the available health services. A meticulous state of readiness is required to respond to any risk of spreading a communicable disease. The state of readiness is maintained by several steps including preparation of staff, equipment, and buildings.3,4 The burden of not maintaining effective public health event response measures is aggravated if an epidemic is announced in a particular region of the globe where travellers form these areas are scheduled to arrive in the country. During the Hajj season of 2014, the Ebola Virus Disease (EVD), which is a viral hemorrhagic disease, was announced as an epidemic disease in Guinea, Liberia, and Sierra Leone in West Africa. Additionally, a localized spread of the virus was announced in certain areas of Nigeria.5 The Saudi Arabian government, as a preventive measure, decided to prevent citizens of EVD-affected countries from entering the country. However, nationals of Nigeria were exempt as no extended transmission of EVD was announced.6,7 Nonetheless, several procedures were applied to prevent the transmission of Ebola virus among thousands of Nigerian pilgrims arriving in the country. These measures were mainly related to exit screening of travellers in Nigeria,8 and entry screening at points of entry in Saudi Arabia. Additionally, the Ministry of Health in Saudi Arabia produced response plans for infectious diseases (Middle East Respiratory Syndrome [MERS] and EVD) to be implemented during Hajj.9 There are many potential sources of infectious disease transmission from a single infected individual. The presence of infected travellers, such as an EVD infection, on an aircraft increases the risk of transmitting infection to neighboring passengers and flight crew. Airport workers, such as ground workers handling cleaning of aircrafts and lavatories, are at risk of the infection, especially with the presence of spilled infectious materials. Airport workers handling the flow of passengers during busy times are at risk of acquiring infection such as immigration, customs, security, and healthcare workers. Therefore, all of these individuals have to be aware of the potential health threats at the airport, should be aware of preventive methods, how to use preventive methods, and know what to do when facing a public health emergency event in the airport. Prince Mohammed Airport (Al-Madinah, Saudi Arabia) workers’ level of knowledge of the potential health threat at the airport is currently not known. Additionally, the attitude and practice of the staff when a public health emergency is announced in the airport is not measured. The significance of this study stems from the ability to investigate the degree to which airport workers, at the time of dealing with travellers during Hajj season, were able to deal with potential urgent infectious cases, and to adhere to the relevant protective guidelines. 相似文献54.

Background
Coronary computed tomography angiography (CCTA) is increasingly being used for the evaluation of coronary artery disease; however, radiation exposure remains a major limitation of its use.Objective
To compare image quality and radiation exposure in two groups of patients undergoing CCTA using a 256-slice dual-source helical computed tomography scanner with high-pitch (FLASH) or prospective [step-and-shoot (SAS)] gating protocols.Methods
A prospective, single-center study was performed in our cardiac center. In total, 162 patients underwent CCTA with either FLASH or SAS scanning protocols. Subjective image quality was graded on the basis of a four-point grading system (1, non-diagnostic; 2, adequate; 3, good; 4, excellent). Objective image quality was assessed using image signal, noise, and signal-to-noise ratio (SNR). The effective radiation dose was also estimated.Results
The clinical and demographic characteristics of the patients in both groups were similar. The median age of the patients in both groups was 48.43?years, and males accounted for 63% and 68.7% of the FLASH and SAS groups, respectively. We found that the subjective image quality obtained with the FLASH protocol was superior to that obtained with the SAS protocol (3.35?±?0.6?mSv vs. 2.82?±?0.61?mSv; p?<?0.001). Image noise was higher in the FLASH group but was not statistically significant (25.0?±?6.13 vs. 24.0?±?6.8; p?=?0.10), whereas the signal and SNR was significantly higher with the FLASH protocol than with the SAS protocol [(469?±?116 vs. 397?±?106; p?>?0.001) and (21.6?±?8.7?mSv vs. 16.6?±?7.7?mSv; p?<?0.001), respectively]. Radiation exposure was 62% lower in the FLASH protocol than in the SAS protocol, (1.9?±?0.4?mSv vs. 5.12?±?1.8?mSv; p?<?0.001).Conclusion
The use of 256-slice CCTA performed with the FLASH protocol has a better objective and subjective image quality as well as lower radiation exposure when compared with the use of prospective electrocardiography gating. 相似文献55.

Background
Septic arthritis of the costovertebral thoracic joint is a rare site infection. We report an isolated case of septic arthritis of the 10th costo-vertebral right joint with osteitis due to Staphylococcus aureus.Case presentation
A 59 year old Tunisian man presented with a 2 months history of dorsal spinal pain with fever, associated with asthenia, anorexia and loss of weight. There was a raised C-reactive protein (176 mg/L) and erythrocyte sedimentation rate (100 mm/1st h). Tests for tuberculosis and brucellosis were negative. In the present patient, the clinical symptoms were unspecific with lack of obvious predisposing factors. He had neither history of taking immunosuppressors nor of any disease indicative of immunodeficiency. Thoraco-abdominal computed tomography (CT) showed a lytic lesion centered on the 10th costo-vertebral right joint and histo-pathologic exam of the costo-vertebral puncture confirmed chronic active osteitis and bacteriologic culture allowed identifying methicillin-sensitive Staphylococcus aureus. The patient was treated with ciprofloxacin 1500 mg/day, associated with daily rifampin (20 mg/kg) for total treatment duration of 12 weeks after consulting infectious disease specialists. After a follow-up of 6 months, the patient remained asymptomatic and the markers of inflammation negative.Conclusion
Septic arthritis of costovertebral joints should be considered when a patient presents with back pain, fever and elevated inflammatory markers. The diagnosis of septic arthritis of costovertebral joints remain a challenge to clinicians. CT is important to confirm a diagnosis and guide costovertebral biopsy and culture. Early and appropriate antibiotic therapy is important for a required outcome. 相似文献56.

Dipeptidyl peptidase-4 expression in pancreatic tissue from patients with congenital hyperinsulinism
Sofia A Rahman Senthil Senniappan Maha Sherif Sophia Tahir Khalid Hussain 《International journal of clinical and experimental pathology》2015,8(7):8199-8208
Congenital hyperinsulinism (CHI) is caused by unregulated insulin release and leads to hyperinsulinaemic-hypoglycaemia (HH). Glucagon like peptide-1 (GLP-1), glucose-dependent insulinotropic peptide (GIP), peptide YY (PYY) and the enzyme; dipeptidyl peptidase-4 (DPP-4) all regulate appetite and glucose homeostasis. These proteins have been identified as possible contributors to HH but the mechanism remains poorly understood. We aimed to look at the expression pattern of pancreatic DPP-4 in children with focal and diffuse CHI (FCHI and DCHI, respectively). Using immunohistochemistry; we determined DPP-4 expression patterns in the pancreas of CHI patients. DPP-4 was found to be expressed in the pancreatic β, α and δ-cells in and around the focal area. However, it was predominantly co-localised with β-cells in the paediatric tissue samples. Additionally, proliferating β-cells expressed DPP-4 in DCHI, which was absent in the FCHI pancreas. Insulin was found to be present in the exocrine acini and duct cells of the DCHI pancreas suggestive of exocrine to endocrine transdifferentiation. Furthermore, 6 medically-unresponsive DCHI pancreatic samples showed an up-regulation of total pancreatic DPP-4 expression. In conclusion; the expression studies have shown DPP-4 to be altered in HH, however, further work is required to understand the underlying role for this enzyme. 相似文献

Risk factors for hospital admission among COVID-19 patients with diabetes: A study from Saudi Arabia
Ayman A. Al Hayek Asirvatham A. Robert Abdullah Bin Matar Ali Algarni Haneen Alkubedan Turki Alharbi Afrah Al Amro Seham A. Alrashidi Mohamed Al Dawish 《Saudi medical journal》2020,41(10):1090
Objectives:To elucidate the risk factors for hospital admission among COVID-19 patients with type 2 diabetes mellitus (T2DM).Methods:This retrospective study was conducted at the Prince Sultan Military Medical City, Riyadh, Saudi Arabia between May 2020 and July 2020. Out of 7,260 COVID-19 patients, 920 were identified as T2DM. After the exclusion process, 806 patients with T2DM were included in this analysis. Patients’ data were extracted from electronic medical records. A logistic regression model was performed to estimate the risk factors of hospital admission.Results:Of the total of 806 COVID-19 patients with T2DM, 48% were admitted in the hospital, 52% were placed under home isolation. Older age between 70-79 years (OR [odd ratio] 2.56; p=0.017), ≥80 years (OR 6.48; p=0.001) were significantly more likely to be hospitalized compared to <40 years. Similarly, patients with higher HbA1c level of ≥9% compared to <7%; (OR 1.58; p=0.047); patients with comorbidities such as, hypertension (OR 1.43; p=0.048), cardiovascular disease (OR 1.56; p=0.033), cerebrovascular disease (OR 2.38; p=0.016), chronic pulmonary disease (OR 1.51; p=0.018), malignancy (OR 2.45; p=0.025), chronic kidney disease (CKD) IIIa, IIIb, IV (OR 2.37; p=0.008), CKD V (OR 5.07; p=0.007) were significantly more likely to be hospitalized. Likewise, insulin-treated (OR 1.46; p=0.03) were more likely to require hospital admission compared to non-insulin treated patients.Conclusion:Among COVID-19 patients with diabetes, higher age, high HbA1c level, and presence of other comorbidities were found to be significant risk factors for the hospital admission. 相似文献
