Seventy seven antral biopsies were collected from patients attending endoscopy clinic at King Khalid University Hospital, Riyadh, Saudi Arabia during a period of six months between December 1988 to May 1989. Of these 69 (89.6%) showed chronic gastritis as well as Helicobacter-like organisms (HLOs) in the biopsy specimens while 63 (81.8%) of biopsies grew Helicobacter pylori on culture. These findings indicate a good correlation between the histological diagnosis of chronic gastritis and isolation of H. pylori on culture. 相似文献

We are currently facing an obesity pandemic, with worldwide obesity rates having tripled since 1975. Obesity is one of the main risk factors for the development of non-communicable diseases, which are now the leading cause of death worldwide. This calls for urgent action towards understanding the underlying mechanisms behind the development of obesity as well as developing more effective treatments and interventions. Appetite is carefully regulated in humans via the interaction between the central nervous system and peripheral hormones. This involves a delicate balance in external stimuli, circulating satiating and appetite stimulating hormones, and correct functioning of neuronal signals. Any changes in this equilibrium can lead to an imbalance in energy intake versus expenditure, which often leads to overeating, and potentially weight gain resulting in overweight or obesity. Several lines of research have shown imbalances in gut hormones are found in those who are overweight or obese, which may be contributing to their condition. Therefore, this review examines the evidence for targeting gut hormones in the treatment of obesity by discussing how their dysregulation influences food intake, the potential possibility of altering the circulating levels of these hormones for treating obesity, as well as the role of short chain fatty acids and protein as novel treatments. 相似文献

Emotionality truly shapes critical thinking in the development of American health policy. President Obama has misgauged the emotions and thoughts of the Nation and Congress about the health care reform bill. Most Americans don??t approve of the design or impetus of health care legislation under the Obama administration. The enacted legislation provides health care insurance for all Americans. However, health care insurance for the lower class shows intense ??red lights?? for repeal of the legislation to members of the middle and upper classes. It violates their critical thinking processes and comes down to a kind of ??class warfare?? of poverty level and low income persons against the gut emotional feelings of the middle and upper classes to repeal the program. Sarah Palin and her Tea Party compatriots envision such ??class warfare?? with the implementation of the program, even ??death panels?? to mete out health care for those seriously or gravely ill. 相似文献

Background: Subjective radiographic classifications of alveolar bone have been proposed and correlated with implant insertion torque (IT). The present diagnostic study aims to identify quantitative bone features influencing IT and to use these findings to develop an objective radiographic classification for predicting IT. Methods: Demographics, panoramic radiographs (taken at the beginning of dental treatment), and cone‐beam computed tomographic scans (taken for implant surgical planning) of 25 patients receiving 31 implants were analyzed. Bone samples retrieved from implant sites were assessed with dual x‐ray absorptiometry, microcomputed tomography, and histology. Odds ratio, sensitivity, and specificity of all variables to predict high peak IT were assessed. Results: A ridge cortical thickness >0.75 mm and a normal appearance of the inferior mandibular cortex were the most sensitive variables for predicting high peak IT (87.5% and 75%, respectively). A classification based on the combination of both variables presented high sensitivity (90.9%) and specificity (100%) for predicting IT. Conclusions: Within the limitations of this study, the results suggest that it is possible to predict IT accurately based on radiographic findings of the patient. This could be useful in the treatment plan of immediate loading cases. 相似文献

Objectives
The aim of this study was to evaluate the strength of the bond between newly introduced self-adhesive resin cements and tooth structures (i.e., enamel and dentin).Methods
Three self-adhesive cements (SmartCem2, RelyX Unicem, seT SDI) were tested. Cylindrical-shaped cement specimens (diameter, 3 mm; height, 3 mm) were bonded to enamel and dentin. Test specimens were incubated at 37 °C for 24 h. The shear bond strength (SBS) was tested in a Zwick Roll testing machine. Results were analyzed by one-way ANOVA and t-test. Statistically significant differences were defined at the α = 0.05 level. Bond failures were categorized as adhesive, cohesive, or mixed.Results
The SBS values ranged from 3.76 to 6.81 MPa for cements bonded to enamel and from 4.48 to 5.94 MPa for cements bonded to dentin (p > 0.05 between surfaces). There were no statistically significant differences between the SBS values to enamel versus dentin for any given cement type. All cements exhibited adhesive failure at the resin/tooth interface.Conclusions
Regardless of their clinical simplicity, the self-adhesive resin cements examined in this study exhibit limited bond performance to tooth structures; therefore, these cements must be used with caution. 相似文献9.

Objectives:
To assess health care services provided to type 1 and type 2 diabetic patients and diabetes health care expenditure in the Kingdom of Saudi Arabia (KSA).Methods:
This study was part of a nationwide, household, population based cross-sectional survey conducted at the University Diabetes Center, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia between January 2007 and December 2009 covering 13 administrative regions of the Kingdom. Using patients’ interview questionnaires, health care services data were collected by trained staff.Results:
A total of 5,983 diabetic patients were chosen to assess health care services and expenditure. Approximately 92.2% of health services were governmental and the remaining 7.8% were in private services. The mean annual number of visits to physicians was 6.5±3.9 and laboratories was 5.1±3.9. Diabetic patients required one admission every 3 years with a mean admission duration of 13.3±28.3 days. General practitioners managed 85.9% of diabetic cases alone, or shared with internists and/or endocrinologists. Health care expenditure was governmental in 90% of cases, while it was personal in 7.7% or based on insurance payment in 2.3%.Conclusion:
Health services and its expenditure provided to diabetic citizens in Saudi Arabia are mainly governmental. Empowerment of the role of both the private sector and health insurance system is badly needed, aside from implementing proper management guidelines to deliver good services at different levels.The health care system (HCS) in the Kingdom of Saudi Arabia (KSA) is growing at an annual rate of 2% to meet the increasing demand for health care services caused by increased population growth, and a surge in chronic non-communicable diseases.1 This has resulted in an increase in the total health care budget by more than 2 times; from 30 billion Saudi Riyals (SR) (US$8 billion) in 2008 to approximately SR69 billion (US$18.4 billion US dollars) in the year 2011 with a cumulative allocation of SR113 billion (U$30.13 billion) in 2010 and 2011; which accounted for 3.7% of the estimated country’s gross domestic product (GDP), which is one of the highest among Gulf Cooperation Council (GCC) countries.2 The Saudi health care system, which is ranked 26th among 190 countries by the World Health Organization (WHO),3 has a lower percentage of average expenditure in relation to the country’s GDP than many developed and developing countries.4 The government HCS in KSA is structured to deliver free health care services to Saudi citizens through various public hospitals and primary health care centers (PHCCs) including government health sectors, such as the Ministry of Health (MOH), Military Health Services and University Health Institutions. In addition to this, the private health care sector, through its clinics and hospitals, provided 31.1% of the total health care services in KSA in 2013.5 The real challenge facing the Kingdom’s HSC is the increased demands for hospital beds and medical personnel to meet international standards.6 The population ratio of physician and nurses in the Kingdom is lower than the global ratio being 9.4 physicians and 21 nurses per 10,000 of population versus 13 physicians and 28 nurses globally.7 This explains the current imbalance between the growth in HCS and the real medical needs of Saudi citizens.Diabetes mellitus, being the most prevalent chronic non-communicable disease in the Kingdom, has a significant effect on the country’s HCS and overall economy.8,9 This is proved by the fact that 25.4% of Saudi citizens older than 30 years of age have diabetes, which implies that there are approximately 1.5 million Saudi citizens suffering from this chronic disease.10 This is aside from the fact that more than 70% of known diabetic patients in the Middle Eastern countries have poorly controlled diabetes,11 associated with high rates of chronic complications that place greater pressure on health services and expenditure, where in 2013, it was estimated that the Middle East and North Africa (MENA) region spent US$13.6 billion on diabetes care with the spending per person with diabetes, where the spending in Saudi Arabia was US$934, which is far below other GCC such as United Arab Emirates (US$2,228), Qatar (US$2,199), and Kuwait (US$1,886),12 although we strongly believe that these figures are underestimated.Diabetic patients are currently managed at all health care levels, from primary to secondary and tertiary levels by general practitioners (GPs), internists, and endocrinologists.13 Since diabetes care involves many medical disciplines, such as ophthalmology, cardiology, nephrology and so forth, specialized diabetes clinics, and diabetes centers are needed to function as liaising bodies. Although health care needs for diabetic patients’ management at a global level have witnessed a clear shift to the primary from secondary and tertiary health care levels,14 diabetic patients in the Kingdom are still receiving services at secondary or even tertiary levels. Since there are no studies so far that have looked into the health care services provided to diabetic patients in KSA, the current study, as a part of the Saudi Abnormal Glucose Metabolism and Diabetes Impact (SAUDI-DM) survey,10 has investigated the current status of health care services provided to diabetic patients. This study aimed to assess the medical system providing care to diabetic patients, and methods of payment through a randomly selected cohort of diabetic patients at a country level. 相似文献10.
