TRANSDERMAL OF ATENOLOL VIA MICROEMULSIONS

Objective: Developing novel non-ionic microemulsions (MEs) for transdermal of atenolol as satisfactory alternative drug delivery systems for the oral route. Methods: Seven MEs were developed then checked for encapsulation of atenolol using Fourier Transform Infrared Spectroscopy (FTIR-spectroscopy) (), isotropy, droplet sizes, rheological properties and transdermal flux using Franz diffusion cell. Furthermore, two MEs with best flux values were selected for bioavailability evaluation after transdermal application over rat’s skin. Results: The results showed that the MEs complies with colloidal systems properties. Also, the developed MEs were stable throughout the study, ideal viscous systems with droplet sizes below 500 nm and isotropic. Besides, FTIR-spectra could reveal the structure of the MEs and encapsulation of atenolol inside the dispersed phase. Moreover, the flux values of atenolol in MEs through rat’s skin varied with different factors such as atenolol concentration, MEs’s composition, and zetapotential. The highest flux value of the developed systems was 243.5±16.3 µg. cm-2. h-1. Furthermore, the in vivo results showed that using the two tested microemulsions maximum plasma levels of atenolol 5.22±0.43 and 4.06±0.15 mg. ml-1at 8.18 and 3.64 h respectively could be achieved. Conclusion: The developed microemulsions can be promise formulations for transdermal administration of atenolol as alternative for oral tablets

Public knowledge, beliefs, psychological responses, and behavioural changes during the outbreak of COVID - 19 in the Middle East

Objective : To evaluate the knowledge, believes, psychological and behavioural impact of COVID - 19 on the general population in the Middle East, exploring how it impacted public lives. Methods : A descriptive cross - sectional online survey was sen t to a convenience sample in the Middle East through social media (Facebook and WhatsApp) between 16 th of June and 30 th of June 2020. The questionnaire was designed to collect the demographic, participant’s source of information regarding COVID - 19, knowled ge and believes about COVID - 19, the psychological consequences of COVID - 19, impact of COVID - 19 on participant’s behaviour. The final version of the questionnaire was further tested for content validity by experts in the field. Results : A total of 2,061 par ticipants completed the survey, with the majority being females (n=1394, 67.6%), from urban areas (n=1896, 92%) and the majority were from countries of The Levant (n=1199, 58.1%), followed by the Arabian Peninsula (n=392, 1 9.1%), Iraq (n=300, 14.6%) and Eg ypt (n=138, 6.7%). Few participants (3.0%) reported to have been infected and many (n=1847, 89.6%) were committed to quarantine at home. Social media platforms were the most common sources of information (41.2%). Many (63%) believed that COVID - 19 is a biol ogical weapon and were afraid of visiting crowded places (85%). The majority avoided public facilities (86.9%) such as prayer places and believed that the news about COVID - 19 made them anxious (49.5%)

A comprehensive overview of substance abuse amongst Syrian individuals in an addiction rehabilitation center

Objectives: This study aims to provide a comprehensive overview of substance abuse amongst Syrian individuals in an addiction rehabilitation center. Methods: This is a descriptive cross-sectional survey-based study, from patients receiving treatment in an addiction rehabilitation center in Damascus. Syria. The study was conducted over a period of nine months. Results: A total of 82 participants were recruited, the majority of them were males (n = 78.95.1%). More than half of those investigated reported multi-level failure (n = 46, 56.1%) during their education. Most of the participants (n = 44, 53.7%) started to use drugs at a friend’s home. The family was shown to play a positive role in stopping the initial drug taking trials at early stages (33/56, 58.9%). Again, friends' effect was the main reason for the return of abusing drugs (20/56, 35.7%). Sources of drugs were mainly from drug promoters for most of the participants (n = 58, 70.7%) followed by friends (n = 28, 34.1%). Participants revealed that taking drugs were mostly accompanied by additional habits such as cigarette smoking before using their drugs (n = 65, 79.3%), or drinking alcohol (57.3%). Surprisingly, participants believed that drug abuse does not lead to addiction (n = 52, 63.4%). The most common experienced feeling was depressed, desperate, or sad (n = 47, 57.3%), followed by anxiety and the desire to escape reality and resort to imaginations (n = 44, 53.7%). Conclusions: The findings of this study indicate the need of policymakers to give more attention, in developing preventive strategies, to friends, as a main cause of addiction, in addition to the family influences on individual’s drug abuse, addiction behaviors, and mindsets. Understanding the influencing factors could spot the light on the key to solve the addiction problem. A realist rehabilitation programs must be well designed and implemented as the level of individuals, institutions and communities to face this problematic addiction disaster

Interleukin 6 (IL6) as a potential interplaying factor between obesity and COVID-19 outcome

Background: Obesity is associated with chronic low-grade inflammation and severe COVID-19. Interleukin 6 (IL6) is a key mediator of cytokine storm hyperinflammation. However, it is unknown if IL6 is involved in the link between obesity and COVID-19 outcomes. Methods: Observational retrospective research was conducted between September 8, 2020, and September 30, 2021. BMI-varying COVID-19 patient data were collected. Demographic, clinical, radiographic, and laboratory variables were assessed. COVID-19 outcomes were examined in relation to body mass index () and IL6 levels. Results: More than half of the participants (60.4 %) were elderly individuals. A quarter of the study population was non-obese, and 6.6 % had 3rd-degree obesity. Individuals with normal weight and class I obesity had higher IL-6 levels (70.1 % and 75.6 %, respectively). Severe cases were more likely to have higher IL-6 levels than non-severe cases (p < 0.05, OR = 7.221). However, we did not find a significant association between BMI and odds of mortality (p = 0.05). Conclusion: People with severe COVID-19 illness, class 1 obesity, and those requiring intensive care unit admission had considerably higher levels of IL6, however our study found no association between BMI categories and mortality. Further research is required to investigate the interplay between obesity and COVID-19 outcomes

A multinational study on the factors influencing university students’ attitudes and usage of ChatGPT

Abstract Artificial intelligence models, like ChatGPT, have the potential to revolutionize higher education when implemented properly. This study aimed to investigate the factors influencing university students’ attitudes and usage of ChatGPT in Arab countries. The survey instrument “TAME-ChatGPT” was administered to 2240 participants from Iraq, Kuwait, Egypt, Lebanon, and Jordan. Of those, 46.8% heard of ChatGPT, and 52.6% used it before the study. The results indicated that a positive attitude and usage of ChatGPT were determined by factors like ease of use, positive attitude towards technology, social influence, perceived usefulness, behavioral/cognitive influences, low perceived risks, and low anxiety. Confirmatory factor analysis indicated the adequacy of the “TAME-ChatGPT” constructs. Multivariate analysis demonstrated that the attitude towards ChatGPT usage was significantly influenced by country of residence, age, university type, and recent academic performance. This study validated “TAME-ChatGPT” as a useful tool for assessing ChatGPT adoption among university students. The successful integration of ChatGPT in higher education relies on the perceived ease of use, perceived usefulness, positive attitude towards technology, social influence, behavioral/cognitive elements, low anxiety, and minimal perceived risks. Policies for ChatGPT adoption in higher education should be tailored to individual contexts, considering the variations in student attitudes observed in this study
