Knowledge about anesthesia and the role of anesthesiologists among Jeddah citizens

Background: The anesthesiologist has a vital role in the operating theatres. Awareness of the role of the anesthesiologist and the types of anesthesia is essential for every person. This study was made to estimate how much information the general population have about the anesthesiologist and the different types of anesthesia.Methods: This research was a cross sectional non-interventional study. The research team conducted a questionnaire in which each participant in the study was interviewed by the research team. The sample size was 159 participants.Results: From the participants,99 (62.2%) recognized the anesthesiologist as a specialized doctor who administers the anesthetics,62 (38.9%) know that the anesthesiologist has a role in resuscitating the patient with the team if crises occurred. However, 85 (53.4%) believe that the surgeon has the responsibility of postoperative pain management. Physicians were the source of knowledge for most participant’s information.Conclusions: A reasonable percentage of people appreciated the role of the anesthesiologist in administrating the anesthesia, however there is a lack of information about the role of the anesthesiologist intra and postoperatively. The need for more education for people about anesthesia is essential as the amount of information about anesthesia in general is rather low

Influence of sports facilities and programs on sports participation at Saudi Universities

Participation in physical activity without doubt has many benefits especially to students at all levels. It is however worrisome to note that this participation by a number of factors including availability of sport facilities and sport programs. Hence, the purpose of this study was to investigate the role or influence of sport facilities and programme on the participation in physical activity among the students in Saudi Arabia. In order to do this, the study adopted a descriptive approach with data collected with the aid of an adapted questionnaire administered on 643 undergraduate students who were randomly selected from 25 universities in Saudi Arabia. The data collected were analysed using Smart PLS software. It was revealed that there were inadequate sport facilities in the universities and this greatly affected students’ sports participation at Saudi Arabia universities. In addition, findings revealed that (non)availability of sports programs had effects on the students’ sports participation at Saudi Arabia universities. Therefore, these results showed that sports facilities provided by the universities could positively encourage students to use these facilities and participate in sports activities and that the sports programs provided by the universities had significant effect on students’ participation. The study thus concluded that in order to increase the participation level of students, universities should offer them different types of programs, workshops and training, which enable them to discover their skills and participate in the sports that they believe they can enjoy the most with their colleagues. There should also be adequate provision of sport facilities for the use of the students. It is believed that through these, the students and the country will drive the maximum benefits of sports and sport participation

Cross-sectional study identifying forms of tobacco used by Shisha smokers in Pakistan

OBJECTIVES: To estimate the frequency of different forms of tobacco intake such as smoker\u27s tobacco, chewable tobacco and snuff tobacco among shisha smoker\u27s and to study the patterns and predictors of shisha smoking affecting youth from different cities of Pakistan. METHODS: A cross-sectional study was conducted including youth from four cities. Participants were asked to fill out a data collection tool at shisha cafes, shopping malls and restaurants. Data was analyzed using SPSSv.18. RESULTS: A total of 406 participants, 296 (73%) males and 110 (27%) females were included in the study. There were 163 (40%) cigarette smokers; 65 (16%) chewed tobacco and 33 (8%) snuffed it. The median age at initiation of Shisha smoking was 20 years. 280 (69%) considered Shisha smoking to be less deleterious to health than cigarettes. Respiratory disease was the most commonly cited health effect reported. Most 248 (61%) of the participants were infrequent shisha smokers. CONCLUSION: There is high frequency of tobacco usage in the form of cigarettes, chewable tobacco and snuff tobacco among shisha smokers of Pakistan. The highest frequency is for cigarette smoking. The rise in Shisha smoking as a trendy social habit appears to be occurring despite emerging scientific evidence of its potential health risks

General Anesthesia: Observing and Monitoring the Post-operative Complications

The aim of this research was to analyze the post-operative complications of general anesthesia and by utilizing that information, to plan and produce a comprehensive detailed layout of the literature related to the subject investigated. More than 200 studies were surveyed, and the data collected was organized with a systematic layout of the observing and monitoring processes of the post-operative general anesthesia complications. The study concluded that post anaesthetic observations and monitoring are an essential requirement for patient assessment and the recognition of clinical deterioration in post-operative patients. There is disparity in the literature as to what constitutes ‘standard’ routine post anaesthesia orders, so in line with the observation and continuous monitoring guidelines

Prevalence of prediabetes, diabetes, and Its associated risk factors among males in Saudi Arabia: A population-based survey

Objectives: The study aims at determining the prevalence of prediabetes and diabetes and at ascertaining some concomitant risk factorsamong males in Saudi Arabia.Methods: A population-based cross-sectional study including 381 Saudi adult males from different institutions was recruited. Odds ratios for diabetes risk and risk factors were calculated using log-binomial and multinomial logistic regression, using STATA version 12.Results: The participants included 381 diabetic males with a median age of 45 years, average body mass index of 25 ± 40 kg/m2, whereas waist circumferences ranged from 66 to 180 cm in the male study population. In addition, 27.82% had normal BMI, 32.28% were overweight, and 36.22% were obese. Around 36% had higher waist circumference, that is, \u3e102 cm. Age, BMI, marital status, and educational attainment were statistically significant predictors for prediabetes and diabetes.Conclusion: This study found that the prevalence of diabetes and prediabetes was 9.2% and 27.6%, respectively, for male Al-Kharj study population. The factors that increase the risk of diabetes and prediabetes include older age, obesity and overweight, being married, smoker, and having a civilian job and less education. All these factors were found statistically significant except smoking status and job type. In order to evaluate the causal relationship of these factors, prospective studies are required in future

Prevalence of prediabetes, diabetes and Its predictors among females in alkharj, saudi arabia: A cross-sectional study.

BACKGROUND/OBJECTIVE: The prevalence of prediabetes and diabetes is reaching epidemic proportions across the globe. Therefore, this study aims to determine the prevalence of prediabetes and diabetes, together with its accompanying risk factors, among young females. METHODS: An exploratory cross-sectional survey was conducted with 638 Saudi females in Alkharj, Saudi Arabia. Statistical analysis was carried out using STATA version 14. Odds ratios for the risk of diabetes and associated factors were calculated using log-binomial and multinomial logistic regression. Standardized prevalence and strata-specific prevalence of diabetes and prediabetes for different risk factors were also calculated. FINDINGS: The study revealed that nondiabetics and prediabetics were more prevalent between the ages of 18 and 24 years, while diabetic patients were consistently between 25 to 44 years of age. The average value for HbA1c in females was 5.44. Regression analysis shows that being older, married, obese, a smoker or less educated significantly increases the risk for both prediabetes and diabetes. Mutivariable analysis revealed obesity had a significant association with both prediabetes and diabetes. Prediabetics were 2.35 times more likely to be obese as compared to nondiabetics, with 95% CI (1.38-3.99). Similarly, diabetics were 6.67 times more likely to be obese compared to nondiabetics 95% CI (1.68-26.42). CONCLUSION: Our study shows the prevalence of diabetes and prediabetes among females from Al Kharj was 3.8% and 18.8%, respectively. The diabetic and prediabetic female participants had higher mean BMI and waist circumference, were older in age, were married, and smoked as compared to nondiabetics. In the context of the findings of our study, and keeping in view the the burden of this disease globally and in our population, it has now become extremely important to understand these factors and encourage health-promoting behaviors to construct effective interventions

A robust computational investigation on C₆₀ fullerene nanostructure as a novel sensor to detect SCNˉ

This study explored on the adsorption properties and electronic structure of SCNˉ via density functional theory analysis on the exterior surfaces of C₆₀ and CNTs using B3LYP functional and 6-31G** standard basis set. Then adsorption of SCNˉ through nitrogen atom on the C60 fullerene is electrostatic (₋48.02 kJ molˉ1) in comparison with the C₅₉Al fullerene that shows covalently attached to fullerene surface (₋389.10 kJ mol̄ˉ1). Our calculations demonstrate that the SCNˉ adsorption on the pristine and Al-doped single-walled CNTs are ₋173.13 and ₋334.43 kJ molˉ1, indicating that the SCNˉ can be chemically bonded on the surface of Al-doped CNTs. Moreover, the adsorption of SCNˉ on the C₆₀ surface is weaker in comparison with C₅₉B, C₅₉Al, and C₅₉Ga systems but its electronic sensitivity improved in comparison with those of C₅₉B, C₅₉Al, and C₅₉Ga fullerenes. The evaluation of adsorption energy, energy gap, and dipole moment demonstrates that the pure fullerene can be exploited in the design practice as an SCNˉ sensor and C₅₉Al can be used for SCNˉ removal application
