The development of analytical procedures using ICP-OES and ICP-MS for the analysis of trace metals in pharmaceutical formulations

New regulations regarding elemental impurities in pharmaceuticals will be implemented in January 2018 and the guidelines include the use of inductively coupled plasma optical emission spectroscopy (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). In this work, a method using each instrument was developed for the analysis of arsenic (As), cadmium (Cd), mercury (Hg), lead (Pb), cobalt (Co), nickel (Ni) and vanadium (V) and validated to meet the international conference of harmonisation (ICH Q3D) guidelines. Liquid and solid samples were prepared using microwave assisted acid digestion method that was developed using reverse aqua regia. The results obtained from the validation showed good linearity (R2>0.995) with low limits of detections (LODs) and limits of quantifications (LOQs). The percentage recoveries for both the standard reference material (SRM) and the spiked samples were between 95-105% with relative standard deviation (RSD) of less than 5. Cold symptoms relief products were purchased and analysed. Levels of Pb and Cd in certain products were found to exceed the permitted daily exposure limit (PDE) when the maximum dose was taken

Evaluation of knowledge, experiences, and fear toward prescribing and dispensing corticosteroids among Egyptian healthcare professionals: A cross-sectional study

Background: Corticosteroids (CS) are essential drugs in the treatment of several medical conditions. Assuming different roles, physicians and pharmacists play a primary role in prescribing and dispensing these medications to optimize patients' clinical management. The data on assessing knowledge and experience of healthcare professionals toward CS is scarce. Therefore, this study aimed to assess and compare knowledge, experience, and fears towards CS among Egyptian physicians and pharmacists. Methods: A cross-sectional, self-administrated, validated online questionnaire was used to collect the data from Egyptian healthcare professionals. The questionnaire consisted of four sections with multiple choice questions: sociodemographic (7 questions), knowledge about CS (13 questions), experience with CS prescription/dispensing (5 questions), and fears and preferences toward CS prescription/dispensing (13 questions). Descriptive and inferential statistics were used to analyze the data. Results: A total of 600 responses were analyzed in this study. The study sample was almost two-half of healthcare providers: 303 (50.5%) pharmacists and 297 (49.5%) physicians. Pharmacists had marginally higher knowledge scores as compared to those recorded for physicians (11.29 versus 10.16, respectively; P = 0.047). Physicians had more experience choosing corticosteroids in treatment plans based on their experience (51.8% vs 38.5%) and guideline recommendations (72.8% vs 50.9%) than pharmacists. However, pharmacists had more experience dealing with corticosteroid use based on patients' preferences (19.5% vs 4.9%) and showed a broader scope of experiencing side effects of corticosteroids with their patients. The two professions demonstrated high levels of fear, with pharmacists acknowledging significantly lower concerns about CS than physicians (3.72 versus 4.0, respectively; P = 0.003). Conclusion: Discrepancies exist among healthcare professionals in knowledge and experience, favoring better scientific knowledge of pharmacists related to corticosteroids. Based on these findings, the interprofessional collaborative efforts would provide comprehensive, patient-centered care that maximizes the benefits of CS while minimizing their risks

Superior rat wound-healing activity of green synthesized silver nanoparticles from acetonitrile extract of Juglans regia L: Pellicle and leaves

The process of wound healing is complicated. Antimicrobial silver has been one of the substances used for wounds since ancient times. Moreover, traditional medicine has long used Juglans regia L. to promote wound healing. Since eco-friendly nanotechnology has various uses in biomedical research, the aim of this study was to assess the wound-healing capacity of bio-reduced silver nanoparticles (AgNPs). UV, DLS, TEM, and FTIR were used to characterize the prepared AgNPs. Pellicle's bioreduced AgNP (AgNP/P) has a better polydispersity index (PI) of 0.336 compared to its chemically synthesized peers, which have a PI of 0.67. Using incision and excision wound healing models, AgNPs and extracts were compared to Solcoseryl®. Skin-breaking strength, wound contraction, epithelialization time, histology, and cytokines were all assessed. Juglans regia L. pellicle extract (P) has shown significant effectiveness in both models, as well as their bio-reduced partner AgNP/P. The skin's tensile strength following AgNP/P therapy (871 g, p value < 0.05) is comparable to that after Solcoseryl® (928 g), both of which are significantly better than AgNP (592 g) in the incision wound model. Epithelialization time (16.0 and 16.5 days) did not substantially differ from Solcoseryl® (15.3 days) (P value < 0.05). There was an elevated collagen content. Low levels of IL1β (189.0 pg/g) and high levels of TNF-α (1007.1 pg/g) in the case of AgNP/P suggest various cellular kinds of maturation and various wound healing structures that are evident in histopathology investigations. The bioreduced AgNP/P could find use as a pharmaceutical agent for wound healing dressings

Short-term side effects of COVID-19 vaccines: A cross-sectional study in Jordan

The rapid manufacturing of vaccines has increased hesitancy toward receiving the COVID-19 vaccines. Clarifying what to expect after vaccination and revealing the possible side effects will lower hesitancy toward receiving the COVID-19 vaccine and increase public awareness. This descriptive cross-sectional survey-based study was conducted in Jordan (August 2021) to collect data on the short-term side effects following the COVID-19 vaccines. An extensive literature review was conducted by the research team to assist in developing the first draft of the survey. The survey was tested for face and content validity and piloted test to improve readability and clarity. The survey was organized into two sections (demographics and perceived COVID-19 vaccines’ side effects). Data were analyzed using the Statistical Package for Social Science (SPSS). A total of 1,044 participants were enrolled in the study. The most received vaccine among the participants was Pfizer-BioNTech (51.1%). The most frequently reported side effects were sore arm at the injection site (84.65%), fatigue (84.48%), discomfort (65.43%), muscles/joint pain (61.38%), drowsiness (58.73%), and headache (58.38%). More side effects were significantly associated with being older (p = 0.046), having an allergy (p = 0.024) or rheumatoid arthritis (p = 0.023), and participants who take NSAIDs regularly (p = 0.029). Short-term side effects of COVID-19 vaccines seem to be mostly local or transient in nature. Older age and certain comorbidities may increase susceptibility to side effects

Evaluation and molecular modelling of bis-Schiff base derivatives as potential leads for management of diabetes mellitus

Developing a medication to cure and manage diabetes mellitus complications is of interest in medicinal chemistry. Toward this end, six bis-biphenyl-salicylaldehyde Schiff base derivatives have been evaluated for their α-glucosidase inhibition, antiglycation and anti-inflammation potentials. Four compounds (compounds 2–5) showed an excellent α-glucosidase inhibitory effect superior to that produced by acarbose. Additionally, the docking study revealed that these compounds are anchored within the binding pocket of α-glucosidase via hydrogen bonding, π-stacking and hydrophobic interactions, comparable to a high number of hydrogen bonding involved in anchoring acarbose. Interestingly, all tested compounds showed varying degrees of antiglycation activity with superior activity for two of them (compound 1 and compound 6) compared to the standard rutin. Moreover, the results indicated an outstanding anti-inflammatory activity for two compounds (compounds 1 and 6) compared to ibuprofen

Public Knowledge and Perceptions about the Emerging Human Mpox in Jordan: A Cross-Sectional Study

Hundreds of human mpox cases are spreading outside of Western and Central Africa, which could be considered a significant world health problem. In this study, we sought to assess public knowledge and perceptions of human mpox. The study was a cross-sectional survey conducted in Jordan in September–October 2022. All participants were approached through social media portals. A total of 1195 participants agreed to participate in this study. The participants showed a low median knowledge score about human mpox (4.0 out of 15.0, IQR = 5.0), with only 27.9% of the participants (n = 334) correctly identifying that human mpox is not a bacterial disease, and around half of them (n = 589, 49.3%) knowing that this disease affects both genders. Higher monthly income (≥400 JD/month) was significantly associated with better knowledge about the disease. Social media was the most comprehensive source of information about mpox (n = 1018, 85.2%). Finally, 57.3% of the participants (n = 685) believed that mpox would affect social and economic life, like the COVID-19 pandemic. These findings highlight the urgent need for systematic strategies that should be promoted to increase public knowledge of mpox, which will be critical in improving the capacity to respond to the disease

The Effects of Medications and the Roles of Pharmacists on the Recovery of Patients with COVID-19 Infection: An Epidemiological Study from the United Arab Emirates

Patients infected with coronavirus have new experiences and hence new needs from the healthcare sector. Acknowledging patients’ experiences can exhibit promising outcomes in coronavirus management. Pharmacists are considered a vital pillar in managing patients’ experiences during their infection. A cross-sectional study was conducted to assess the experiences of COVID-19-infected individuals and the roles of pharmacists in the United Arab Emirates. The survey was face- and content-validated after being developed. Three sections were included in the survey (demographics, experiences of infected individuals, and the roles of pharmacists). Data were analyzed using the Statistical Package for the Social Sciences. The study participants (n = 509) had a mean age of 34.50 (SD = 11.93). The most reported symptoms among participants were fatigue (81.5%), fever (76.8%), headache (76.6%), dry cough (74.1%), muscle or joint pain (70.7%), and sore throat (68.6%). Vitamin C was the most used supplement (88.6%), followed by pain relievers (78.2%). Female gender was the only factor associated with symptom severity. About 79.0% agreed that the pharmacist played an important and effective role during their infection. The most reported symptom was fatigue, with females reporting more severe symptoms. The role of the pharmacist proved to be vital during this pandemic

Pharmacists’ perceived barriers towards delivering their emergency roles during the COVID-19 pandemic and perceived policymakers’ responsibilities

Rational: In March 2020, the World Health Organization (WHO) declared the coronavirus infectious disease as a pandemic referred to as COVID-19. As an essential service, community pharmacists have been enacting a key role in patient counseling and supply of essential medicines and protective equipment. Objectives: To investigate pharmacists’ perspectives of the role of educational institutes and professional pharmacy organizations in supporting them to take on roles during COVID-19 pandemic and to identify barriers to be able to support themselves and their patients. Methods: This descriptive mixed-method study was conducted via a cross-sectional online survey distributed to pharmacists/pharmacy students in Jordan during the COVID-19 outbreak (15-30 March 2020) using an online questionnaire, followed by an online focus group. Questionnaire items related to participants’ perspectives in being prepared for and supported in their roles during the COVID-19 pandemic and items were tested for face validity. Data were descriptively analyzed using the Statistical Package for the Social Sciences and triangulated with focus group findings. Results: Considering that fear and anxiety are a consequence of mass social distancing/quarantine, study participants (n=726, age=26.9 (SD=8.0) years, 71.9% females), reported needing training on mental healthcare to be able to support themselves and people during pandemics (90.2%). Most respondents agreed/strongly agreed (59.7%) with the statement around pharmacy educators/educational institutes having a key role in preparing pharmacists for practice during epidemics/pandemics, and agreed that their faculties should add a course regarding pandemic preparedness in their curriculum (89.9%). Results were similar regarding roles for the pharmaceutical associations. Focus group findings (n=7) mirrored the survey findings to a large extent. Conclusions: Most participants believed that Pharmacy Educators and pharmaceutical associations have a role in preparing them to deal with the COVID-19 pandemic through online educational workshops/webinars. Online education on mental healthcare is specifically needed
