Copper oxide nanoparticles-loaded zeolite and its characteristics and antibacterial activities

In the present work, a simple and green co-precipitation method was used to prepare copper oxide-zeolite nanocomposites (CuO-zeolite NCs). The weight ratio (1, 3, 5, 8 and 10 wt%) of CuO nanoparticles (NPs) loaded into zeolite was investigated to obtain the optimum CuO distribution for antibacterial activities. The prepared CuO-zeolite NCs were characterized by ultraviolet-visible (UV–vis) spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, powder X-ray diffraction (XRD), and energy dispersive X-ray fluorescence spectrometry (EDXRF). The transmission electron microscopy (TEM) and field emission scanning electron microscopy (FE-SEM) revealed a uniform surface morphology of the CuO-zeolite NCs. The UV–vis spectrum of NCs showed absorption peaks between 230 and 280 nm for nano-CuO in the XRD patterns, and new peaks appeared between (36.56°–38.83°) related to the CuO. At weight ratio less than 10 wt%, the CuO nanoparticles loaded to the zeolite exhibited spherical shapes with average particle diameter of 6.5 nm measured by TEM and XRD. Antibacterial activities were tested against Gram-negative and Gram-positive bacteria. The obtained results showed that, CuO-zeolite NCs with 8 wt% CuO nanoparticles had the highest antibacterial activities against Bacillus Subtilis B29 and Salmonella Choleraesuis ATCC 10708, which can be attributed to the good dispersion of CuO NPs on the zeolite surface

The Prevalence of Obesity among School Students and its Relation to Dietary and Physical Habits

BACKGROUND: Recent studies suggest that unhealthy food practices and lack of exercise are the main cause of the progressive increase in the obesity prevalence. AIM: We aim to assess the prevalence of obesity among school students and its relationship to dietary and physical habits. METHODS: A cross-sectional study from 18 intermediate and high schools located in Taif, Saudi Arabia, between April 2014 and June 2015. We excluded any student with a psychological disease or chronic diseases. We calculated the body mass index (BMI) of students by measuring their height and weight. Dietary, physical, sleep habits, and socioeconomic status were assessed. RESULTS: A total of 2943 students participated with a mean age of 15.4 ± 1.7 years. The majority of these were boys and attending government schools with a mean BMI 22.7 ± 8.6 kg/m2. Overall, 13.6% were overweight and 12.8% were obese. One-third of students report a sedentary lifestyle. Compared to girls, boys were more likely to have lower BMI (p < 0.001), be overweight (p < 0.001), exercise for >300 min/week (p < 0.001), own electronic devices other than smartphone (p < 0.001), use the electronic devices <3 h/day (p = 0.007), eat their meals with their family (p < 0.001), eat fruits and vegetables daily (p < 0.05), exercise for >300 min/week (p < 0.001), and walk to and from school at least once weekly (p < 0.001). CONCLUSION: A quarter of the students were either overweight or obese. Girls were more likely to be obese with less favorable socioeconomic, media consumption, dietary, and physical profiles

Subjective Happiness Assessment among Taif University Medical Students

Abstract Happiness is a very important factor in human life, it is due to happiness that a person can perform tasks in a better or worse way, as it can affect performance. It also could be affected by different factors including study load, smoking, marital status, income, exercise, and study habits. Medical students in particular are subject to have many factors that could influence their happiness level. We conducted a cross-sectional study of 605 medical students at Taif University, Taif, Saudi Arabia that was conducted between August and November of 2015. Students filled a questioner that includes demographic data and validated questions to assess the subjective happiness [the Subjective Happiness Scale (SHS)]. We classified students into happy and unhappy groups according to the score achieved. Those who achieved score more than median were considered to be happy. The primary goal is to assess the level happiness and it's relation to the level of the students, gender, income, study habits, and lifestyle habits. According to the SHS, more students were classified as unhappy (54.4%). The 2nd and 3rd year groups were more likely to be happy (p 0.106). Engaged students were more likely to be happy compared to those who were single or married (p 0.323). Happy students tend to have non-significant higher mean GPA. Happy students were more likely to be younger and reports high/middle income compared to the unhappy group (p <0.05). Those who do exercise for at least 30 min were more likely to be happy compared to those who reports sedentary lifestyle (p 0.146). Students study habits didn't impact the happiness level (p 0.953). According to SHS, more students were considered to be unhappy. The 2nd and 3rd year groups were happier than the other years. Happy students were more likely to be male, younger, engaged, reports high/middle income, higher GPA and exercise more

Medical students’ awareness of and compliance with the hepatitis B vaccine in a tertiary care academic hospital: An epidemiological study

Summary: Background: The hepatitis B virus (HBV) poses a health risk to healthcare workers who are in close proximity to infected individuals. Medical students are a particularly high-risk group due to the lack of an obligatory vaccination program and a post-vaccination screening program to determine immunity status, which results in a lack of awareness of and compliance with the HBV vaccine. Methods: This cross-sectional survey was conducted in King Khalid University Hospital (KKUH), a tertiary care academic hospital in Riyadh, Saudi Arabia, from November 2013 to March 2014. Medical students in their second to fifth years (n = 444; 213 men and 231 women) completed a self-administered questionnaire regarding awareness of HBV and compliance with the HBV vaccination program in KKUH. Results: Medium to low knowledge levels were present in 53.5% of the participants, and 44.3% reported that they were not compliant with the vaccination program provided by KKUH. While 93.9% received the HBV vaccine upon entry to medical school, only 59.5% received all 3 doses, citing forgetfulness and a busy schedule as common reasons for the low compliance. There was no association between the knowledge and awareness of the participants and their compliance (p = 0.988). Conclusion: Medical students had a low level of compliance with the HBV vaccination program, regardless of their knowledge and awareness of the disease and vaccination. We recommend that programs and campaigns be developed to increase the overall awareness of this disease. We also suggest that a mandatory HBV vaccination program should be implemented to improve the compliance rate among medical students.

Nonalcoholic fatty liver disease burden – Saudi Arabia and United Arab Emirates, 2017–2030

Background/Aim: Due to epidemic levels of obesity and type 2 diabetes mellitus (DM), nonalcoholic fatty liver disease (NAFLD) and resulting nonalcoholic steatohepatitis (NASH) will be driving factors in liver disease burden in the coming years in Saudi Arabia and United Arab Emirates (UAE). Materials and Methods: Models were used to estimate NAFLD and NASH disease progression, primarily based on changes in adult prevalence rates of adult obesity and DM. The published estimates and expert interviews were used to build and validate the model projections. Results: In both countries, the prevalence of NAFLD increased through 2030 parallel to projected increases in the prevalence of obesity and DM. By 2030, there were an estimated 12,534,000 NAFLD cases in Saudi Arabia and 372,000 cases in UAE. Increases in NASH cases were relatively greater than the NAFLD cases due to aging of the population and disease progression. Likewise, prevalent cases of compensated cirrhosis and advanced liver disease are projected to at least double by 2030, while annual incident liver deaths increase in both countries to 4800 deaths in Saudi Arabia and 140 deaths in UAE. Conclusions: Continued high rates of adult obesity and DM, in combination with aging populations, suggest that advanced liver disease and mortality attributable to NAFLD/NASH will increase across both countries. Reducing the growth of the NAFLD population, along with potential therapeutic options, will be needed to reduce liver disease burden
