Abstract: The reaction kinetics of catechol or resorcinol with cerium (Ce) ammonium sulfate were spectrophotometrically investigated in polymer media containing polyethylene glycol (PEG 200, 600, 1500, and 4000). Kinetic runs for Ce(IV) were performed under pseudo-first-order reaction conditions. The reaction was found to be first-order for Ce(IV) and fractional orders for catechol, resorcinol, and H+. The presence of PEG caused considerable acceleration of the oxidation of the two substrates. Of note, PEG 4000 presents a distinguished catalytic activity when compared with PEG 200, 600, and 1500 in an acidic medium. The kinetic results were modeled using the Benesi–Hildebrand and Menger–Portnoy equations to explain the nature of the catalytic effects of both PEG forms and substrates. Hence, the efficiency of the reaction was optimal in the presence of resorcinol as a substrate. Based on kinetic features and thermodynamic parameters, probable mechanisms and expected final products are suggested and discussed.

Abstract: Kinetics of the reaction of maltose with cerium ammonium sulfate were analyzed spectrophotometrically by observing the decrease of the absorbance of Cerium(IV) at 385 nm in the presence and absence of polyethylene glycols (600, 1500, and 4000) and Polyvinylpyrrolidone (PVP), in addition to anionic micelles of sodium dodecyl sulfate (SDS), cationic micelles of cetyltrimethylammonium bromide (CTAB) and nonionic micelles of Tween 20 surfactants. Generally, there are few literatures about using the polymers (PEGs and PVP) as catalysts in the oxidation-reduction reactions, therefore the major target of this work was to investigate the influence of the nature of polymers and surfactants on the oxidation rates of maltose by Cerium(IV) in acidic aqueous media, as well as employing the Piszkiewicz model to explain the catalytic effect. The kinetic runs were derived by adaptation of the pseudo first-order reaction conditions with respect to the Cerium(IV). The reaction was found to be first-order with respect to the oxidant and fractional-order to maltose and H2SO4. The reaction rates were enhanced in the presence of polymer and micellar catalysis. Indeed, the surfactants were found to work perfectly close to their critical micelle concentrations (CMC). The electrostatic interaction and H-bonding appear to play an influential role in binding maltose molecules to polymer/ surfactant micelles, while oxidant ions remain at the periphery of the Stern layer within the micelle.

Abstract: Adopting an acoustic framework, this experimental study elucidates the effect of the shadowing technique on the prosodic competence of learners of English whose L1 (Arabic) and English have quite dissimilar phonological systems. It appertains to prosodic aspects such as pauses, stress, and sound length that cause challenges to non-English native speakers. Two individuals of heterogeneous linguistic background participated in a pre-test and a post-test before and after five weeks of shadowing sessions. The data was analyzed acoustically using Praat Software. Findings showed that the participant with the elementary level outperformed the other participant whose level was intermediate, partially because the former was highly motivated to improve her English. The study concluded that shadowing per se is in no way a panacea for improving supra-segmental features unless it is coupled with a motivation to do so, regardless of the level of proficiency.

Abstract: Abstract. Background: Medical nutrition therapy is essential in managing and preventing diseases, and liraglutide plays a critical role in controlling weight and modulating the effectiveness of 5’ AMP-activated protein kinase (5’-AMPK) in the hypothalamus. On the other hand, the neural effects of liraglutide and 5’- AMPK are negatively altered by a high-fat diet (HFD); in addition to that, it remains unclear how normal fat diets combined with liraglutide could counteract the HFD effect. Objectives: To investigate the effects of a high-fat versus normal diet on the neural and thermogenic activities of liraglutide and 5’ –AMPK in the hypothalamus. Methods: We searched the available literature for studies published in PubMed, Science Direct, and ClinicaTrials.gov between November/2020 and January /2021, and we included controlled clinical trials based on the animals’ model issued in the past six years. Findings: A total 101 out of 250 articles were included in our search, and findings revealed that high-fat diets negatively influence liraglutide and 5’-AMPK in the hypothalamus. In contrast, a normal-fat diet could reverse this negative influence if combined with a dose of 1.8-3 mg/kg of liraglutide for up to 16 weeks. Conclusion: High-fat diets counteract the activity of liraglutide and 5’-AMPK in controlling food intake and energy hemostasis in the hypothalamus. Furthermore, we didn’t find adequate studies that examined the effect of combining a normal-fat diet with liraglutide on 5’-AMPK in the hypothalamus; hence, our concern was reviewing and predicting the possible effect of normal-fat diets.

Abstract: Abstract Purpose: Given their negative influence on community health, vaccine hesitancy and resistance are emerging challenges that require healthcare intervention. Therefore, this study aimed to assess the impact of physician-pharmacist collaborative health coaching on rates of hesitancy and resistance for a COVID-19 vaccine. Methods: After an initial assessment of rates of hesitancy and resistance for a COVID-19 vaccine was conducted, hesitant and resistant participants were approached, recruited, and randomized into an active and control group. Pharmacists-physicians collaborative coaching intervention was delivered to active group subjects over two months through Facebook live sessions. The outcome measures were assessed in both groups before coaching, directly after coaching, and a month after coaching. Results: The proportions of hesitancy and resistance for a COVID-19 vaccine among subjects in the active group were significantly reduced from 64.3% and 35.7?fore coaching to 20.1% and 7.8% directly after coaching, respectively. These proportions were further reduced to 11.1% and 3.3% a month after coaching, respectively. Furthermore, the mean scores for knowledge on, and attitude towards COVID-19 vaccine were significantly increased from 4.6 ± 1.8 and 4.1 ± 1.7 before coaching to 7.5 ± 3.1 and 8.9 ± 3.8 directly after coaching, respectively. However, the change in mean score of beliefs about COVID-19 vaccines among active group subjects was not significant. Conclusion: High rates of hesitancy and resistance for a COVID-19 vaccine were found in Jordan. These rates can be significantly reduced through online pharmacists-physicians collaborative coaching, which can also improve knowledge of and attitude towards COVID-19 vaccines.

Research Title: Assessment of A new Strategy to Prevent Prescribing Errors Involving COVID-19 Patients in Community Pharmacies

Author: Asma Ahmad El-Shara, Published Year: 2022

Hospital Pharmacy, April

Faculty: Pharmacy

Abstract: Background: Because COVID-19 patients are vulnerable to prescribing errors (PEs) and adverse drug events, designing and implementing a new approach to prevent prescribing errors (PEs) involving COVID-19 patients has become a priority in pharmacotherapy research. Objectives: To investigate whether using WhatsApp to deliver prescribing error (PE)-related clinical scenarios to community pharmacists could enhance their ability to detect PEs and conduct successful pharmaceutical interventions (PIs). Methods: In this study, 110 community pharmacies were recruited from different regions across Jordan and equally allocated to 2 groups. Over the course of 4 weeks, WhatsApp was used to send PEs-related clinical case scenarios to the active group. The second group was controlled with no clinical scenarios. After completion of the 4-week phase, pharmacists from both groups were asked to document PEs in COVID-19 patients and their interventions using a data-collection form. Results: The incidence of PEs in COVID-19 patients documented in the active group (18.54%) was higher than that reported in the control group (3.09%) (P = .001). Of the 6598 and 968 PIs conducted by participants working in the active and control group pharmacies, 6013 (91.13%) and 651 (67.25%) were accepted, respectively. The proportions of wrong drug (contraindication), wrong drug (unnecessary drug prescribed/no proof of its benefits), and omission of a drug between the active and control groups were 15.30% versus 7.21% (P = .001), 11.85% versus 6.29% (P = .03), and 17.78% versus 10.50% (0.01), respectively. Additionally, the proportions of lethal, serious, and significant errors were 0.74% versus 0.35% (P = .04), 10.52% versus 2.57% (0.002), and 47.88% versus 9.57% (0.001), respectively. Addition of drug therapy interventions (AOR = 0.62; 95% CI, 0.21-0.84) and errors with significant clinical seriousness (AOR = 0.32; 95% CI, 0.16-0.64). Conclusions PEs involving COVID-19 patients in community settings are common and clinically significant. The intervention assessed in this study could be promising for designing a feasible and time-efficient interventional tool to encourage pharmacists’ involvement in identifying and correcting PEs in light of COVID-19.

Faculty: Allied Medical Sciences

Abstract: Recently, significant attention has been given to the effects of obesity-inducing neuroinflammation on the hypothalamus, particularly the activation of glial cells and neurodegenerative sequences. Understanding how high-fat diets provoke neuroinflammation is essential to propose preventative or management strategies combined with medication interventions such as liraglutide. Scientific studies related to obesity and high-fat diet (HFD) in adult humans and rodents and published in PubMed, Science Direct, and ClinicaTrials.gov in the past ten years have been reviewed. The focus has been placed on studies (A) investigating HFD and obesity effects on neuroinflammation and glial cell activation. (B) The effect of liraglutide intervention on neuroinflammation induced by obesity in the hypothalamus. A total of 90 articles fit the inclusion criteria and were included. Findings revealed that induced obesity by HFD is associated with neuroinflammation in the hypothalamus, specifically microglial activation and oxidative stress, and the cellular and molecular mechanisms for this injurious effect are discussed in the review. On the other hand, liraglutide shows promising neuroprotective, antiinflammatory, and anti-apoptosis activities that help manage neurodegenerative diseases. Obesity influences multiple aspects of neuroinflammation in the hypothalamus, including increasing blood-brain barrier permeability, inducing oxidative stress in ER, activating glial cells, and insulin and leptin resistance. It also highlights the consequences of HFD, not only in inducing obesity but also in altering neural integrity. Finally, liraglutide is neuroprotective and limits the initiation of neuroinflammation; therefore, it could be an encouraging therapy for the management of neurodegenerative diseases.
