ABSTRACT
AIMS: To evaluate the effect of silver nanoparticles alone and in combination with Triclosan, and trans-cinnamaldehyde against Staphylococcus aureus and Escherichia coli biofilms on sutures to improve patients' outcomes. METHODS AND RESULTS: Silver nanoparticles were prepared by chemical method and characterized by UV-visible spectrophotometer and dynamic light scattering. The minimum inhibitory concentration was assessed by the Microdilution assay. The antibiofilm activity was determined using crystal violet assay. A checkerboard assay using the fractional inhibitory concentration index and time-kill curve was used to investigate the synergistic effect of silver nanoparticle combinations. The hemolytic activity was determined using an erythrocyte hemolytic assay. Our results revealed that silver nanoparticles, Triclosan, and trans-cinnamaldehyde (TCA) inhibited S.aureus and E.coli biofilms. Silver nanoparticles with TCA showed a synergistic effect (FICI values 0.35 and 0.45 against S. aureus and E. coli biofilms, respectively), and silver nanoparticles with Triclosan showed complete inhibition of S. aureus biofilm. The hemolytic activity was <2.50% for the combinations.

BACKGROUND: Being the professional membership body for pharmacists in Jordan, the Jordan Pharmacists Association (JPA) took the initiative to establish a training centre for practising pharmacists. This study aims to identify the self-assessed training priorities of community pharmacists in Jordan. METHODS: In the period between August and October 2022, an online self-administered questionnaire was distributed using a variety of participants' identification and recruitment approaches. The questionnaire targeted currently practising community pharmacists. Data were analysed descriptively and inferentially. RESULTS: In total, 470 community pharmacists participated in this study. Of 470 participants, 307 (65.3%) were employees, of which 206 were full-time employees. Results showed that only 97 (21%) had access to an in-house training programme or scheme. Self-assessment of training needs highlighted differences between the three competencies clusters. While administrative and managerial skills and competencies were more frequently prioritised on average than the other two clusters, interpersonal and communication skills were needed the least. Evidence showed a significant difference between female and male participants regarding the need for training addressing maternity and early childhood health training issues. Lastly, the role-based comparison showed that, compared to pharmacy owners, employees had a significantly higher need for training related to bookkeeping and taxation returns preparation and how to handle and manage records of narcotic and controlled medicines. CONCLUSIONS: If training and development programmes are tailored to address specific needs in administrative, clinical, and interpersonal competencies, community pharmacists have the potential to enhance public health, expand their role, provide patient-centred care, and support the national healthcare system.

INTRODUCTION: Antimicrobial stewardship programs are intended to improve patient outcomes, reduce side effects, bacterial resistance, and costs. Thus, it is important to assess their impact on an ongoing basis. We aimed to assess the impact of the antimicrobial stewardship program in two different hospitals which used different program approaches. METHODOLOGY: This is a retrospective observational study in two private hospitals [4088 patient records] in Amman- Jordan. Antibiotic susceptibility using antibiogram results, consumption of antibiotics using Defined Daily Dose, and the incidence of Multi-Drug Resistance were recorded using patients' records during 2018, 2019, and 2020. RESULTS: Antimicrobial stewardship program outcomes varied between the two hospitals. Bacterial susceptibility to antibiotics were improved in both hospitals. Moreover, the defined daily dose in Hospital "A" showed no significant change in Fluoroquinolones, Carbapenems, and Piperacillin- Tazobactam, Cephalosporins, and Colistin, while a significant change was observed among Anti-MRSA antibiotics. Finally, the incidence of Extended Spectrum Beta-lactamase [ESBL] E. coli, ESBL Klebsiella, and Vancomycin Resistant Enterococci [VRE] have decreased numerically over the study period, while Methicillin-Resistant Staphylococcus aureus [MRSA] showed an increase in incidence during the second year of the study. CONCLUSION: The study emphasizes the positive impact of the AMS program throughout the three years of the study. Plus, the need to enhance the program through recruiting extra staff and applying extra regulations like implementing educational programs for the hospital staff, designing local guidelines for common ID diseases, and monitoring the program's outcomes which would eventually be more efficient, cost-effective, and safe.

Mucormycosis is a rare but serious fungal infection caused by a group of moulds called mucormycetes. More attention has recently been paid to it due to its association with coronavirus disease 2019 (COVID-19). Thus, it is important to review the progress of studies on mucormycosis and highlight the important findings in relation to epidemiology, clinical manifestation, major risk factors, diagnostic strategies and management. An electronic literature search was performed in PubMed using the keywords: Rhizopus, Mucorales, mucormycosis, zygomycosis, zygomycetes, COVID-19, the drugs (azoles, posaconazole, isavuconazole, amphotericin B pharmaceutical preparations and caspofungin), combination therapy, diagnosis and clinical manifestations. Studies written in the English language from January 1960 to 2021 were considered for this review article. All search results were reviewed, and the relevance of each article was determined by the authors independently. The review emphasized the fact that the diagnosis of mucormycosis is difficult, it is necessary to have a high index of suspicion to identify it, surgical debridement should be done prior to the dissemination of infection to improve clinical outcomes and identifying underlying risk factors is important for proper treatment. Moreover, antifungal therapeutic options are few with polyenes and their combinations should be appropriate for empirical therapy while posaconazole and isavuconazole are best reserved for de-escalation, refractory cases or patients intolerant to amphotericin B.

BACKGROUND: The ongoing spread coronavirus disease worldwide has caused major disruptions and led to lockdowns. Everyday lifestyle changes and antenatal care inaccessibility during the coronavirus disease 2019 (COVID-19) pandemic have variable results that affect pregnancy outcomes. This study aimed to assess the alterations in stillbirth, neonatal-perinatal mortality, preterm birth, and birth weight during the COVID-19 national lockdown. METHODS: We used the data from the Jordan stillbirths and neonatal death surveillance system to compare pregnancy outcomes (gestational age, birth weight, small for gestational age, stillbirth, neonatal death, and perinatal death) between two studied periods (11 months before the pandemic (May 2019 to March 2020) vs. 9 months during the pandemic (April 2020 to March 1st 2020). Separate multinomial logistic and binary logistic regression models were used to compare the studied outcomes between the two studied periods after adjusting for the effects of mother's age, income, education, occupation, nationality, health sector, and multiplicity. RESULTS: There were 31106 registered babies during the study period; among them, 15311 (49.2%) and 15795 (50.8%) births occurred before and during the COVID-19 lockdown, respectively. We found no significant differences in preterm birth and stillbirth rates, neonatal mortality, or perinatal mortality before and during the COVID-19 lockdown. Our findings report a significantly lower incidence of extreme low birth weight (ELBW) infants (<1kg) during the COVID-19 lockdown period than that before the lockdown (adjusted OR 0.39, 95% CI 0.3-0.5: P value <0.001) CONCLUSIONS: During the COVID-19 lockdown period, the number of infants born with extreme low birth weight (ELBW) decreased significantly. More research is needed to determine the impact of cumulative socio-environmental and maternal behavioral changes that occurred during the pandemic on the factors that contribute to ELBW infants.

Sulphonylurea compounds have versatile activities such as antidiabetic, diuretic, herbicide, oncolytic, antimalarial, antifungal and anticancer. The present study describes the design, synthesis and in vivo testing of novel glycosylated aryl sulfonylurea compounds as antihyperglycaemic agents in streptozocine-induced diabetic mice. The rational for the introduction of the glucosamine moiety is to enhance selective drug uptake by pancreatic ß-cells in order to decrease the cardiotoxic side effect commonly associated with sulfonylurea agents. 2-Deoxy-2-(4-chlorophenylsulfonylurea)-D-glucopyranose was found to be the most potent antihyperglycaemic agents among the synthesized compounds in diabetic mice. This investigation indicates the importance of this novel class as potential antihyperglycaemic agents.

Background and Aim: Antibiotic-resistant Pseudomonas aeruginosa poses a serious health threat. This study aimed to investigate the antibacterial activity of peptide KW-23 against drug-resistant P. aeruginosa and its potential for enhancing the efficacy of conventional antibiotics. Materials and Methods: KW-23 was synthesized from nine amino acids, specifically three tryptophans and three lysines. The purity of the substance was analyzed using reverse-phase high-performance liquid chromatography. The peptide was identified through mass spectrometry using electrospray ionization. The minimum inhibitory concentration (MIC) values of KW-23 in combination with conventional antibiotics against control and multidrug-resistant P. aeruginosa were determined utilizing broth microdilution. The erythrocyte hemolytic assay was used to measure toxicity. The KW-23 effect was analyzed using the time-kill curve. Results: The peptide exhibited strong antibacterial activity against control and multidrug-resistant strains of P. aeruginosa, with MICs of 4.5 µg/mL and 20 µg/mL, respectively. At higher concentration of 100 µg/mL, KW-23 exhibited a low hemolytic impact, causing no more than 3% damage to red blood. The cytotoxicity assay demonstrates KW-23's safety, while the time-kill curve highlights its rapid and sustained antibacterial activity. The combination of KW-23 and gentamicin exhibited synergistic activity against both susceptible and resistant P. aeruginosa, with fractional inhibitory concentration index values of 0.07 and 0.27, respectively. Conclusion: The KW-23 synthesized in the laboratory significantly combats antibiotic-resistant P. aeruginosa. Due to its strong antibacterial properties and low toxicity to cells, KW-23 is a promising alternative to traditional antibiotics in combating multidrug-resistant bacteria.
ABSTRACT
OBJECTIVE: The study's aim was to explore academic entitlement among pharmacy students in different pharmacy colleges in the Arab World and assess associated factors. METHODS: This study design was a cross-sectional survey. Data were collected using a self-administered electronic questionnaire posted across pharmacy college networks in 10 Arab countries (Egypt, Iraq, Jordan, Lebanon, Libya, Oman, Palestine, Qatar, Saudi Arabia, and United Arab Emirates). The electronic survey was administered through Qualtrics Survey Software, and its link was open from January 23, 2022 to May 13, 2022. The multiple linear regression measured the association between different predictors and the academic entitlement. RESULTS: A total of 2386 surveys were received from students studying in 10 different Arab countries. The majority of responding students were male and studying in a Bachelor of pharmacy program. Students reported an agreeable attitude in 4 areas: rewards for efforts, customer orientation, customer service expectation, and general academic entitlement. In accommodation, a neutral attitude was reported, while they reported a disagreeing attitude in the responsibility avoidance domain. In grade haggling, the 3 items of the domain had different attitudes. Only 3 factors had a significant negative association with student entitlement (professionalism, GPA, and year in the study program). CONCLUSION: The academic entitlement scores among pharmacy students in the Arab World were high and had a negative association with professionalism perceptions. This study finding is a call for pharmacy programs to consider the effect of academic entitlement on pharmacy education and to obtain in-depth evidence on its magnitude and associated factors.

Introduction: Studies from developed and developing countries showed that the knowledge levels of stroke need improvement. Educational campaigns varied and were of limited influence predominantly because of their short duration and the need for financial support. The study aims to test the impact of a 3-min online video on the knowledge of stroke and factors influencing the knowledge score in four Arab countries. Methods: A cross-sectional web-based pre-post study was conducted in Egypt, Jordan, Lebanon, and the United Arab Emirates. The data were collected using the snowball technique. Participants were adults aged 18 years and above. The questionnaire sequence was conducting a pretest, followed by the educational video explaining stroke occurrence, types, risks, warning signs, preventive measures, and treatment, and finally, a posttest to evaluate the differences in knowledge from baseline. Statistical analysis included paired t-tests comparing pre-post-education stroke knowledge scores, while repeated measures ANOVA, adjusting for covariates, assessed mean changes. Results: The total number of participants was 2,721, mainly younger than 55 years. The majority had a university degree and were not healthcare professionals. A significant improvement was noted in the total knowledge score in all countries from a mean average (Mpretest = 21.11; Mposttest = 23.70) with p < 0.001. Identification of the stroke risks (Mpretest = 7.40; Mposttest = 8.75) and warning signs (Mpretest = 4.19; Mposttest = 4.94), understanding the preventive measures (Mpretest = 5.27; Mposttest = 5.39) and the importance of acting fast (Mpretest = 0.82; Mposttest = 0.85) improved from baseline with (p < 0.001) for all score components. Conclusion: The educational tool successfully enhanced public understanding of stroke risks, the identification of stroke signs, and the critical need for emergency action. The advantages of this video include its short length, free online access, use of evidence-based content in lay language, and reflective images. The ultimate goal remains the long-term improvement of sustainability by mandating full-scale trials.

Background and Aim: Human infections caused by Candida albicans are common and range in severity from relatively treatable skin and mucosal conditions to systemic, fatal invasive candidiasis. The treatment of fungal infections is challenged by major obstacles, including the scarcity of effective therapeutic options, the toxicity of available medications, and the escalating antifungal resistance. Hence, there exists an urgent need to develop new classes of antimicrobial agents. This study was conducted to investigate the effect of KW-23 peptide against standard and resistant strains of C. albicans alone and in combination with fluconazole. Materials and Methods: A conjugated ultrashort antimicrobial peptide (KW-23) was designed and synthesized. KW-23 was challenged against standard and multidrug-resistant C. albicans alone and in combination with fluconazole using standard antimicrobial and checkerboard assays. The toxicity of the peptide was examined using hemolytic assays. Results: KW-23 positively affected the standard and resistant Candidal strains (at 5 and 15 µg/mL respectively), exhibiting potent synergistic antimicrobial activity against the standard strain when combined with fluconazole. The effect of the combination was additive against the resistant strain (0.6 µg/mL). Furthermore, the peptide exhibited negligible toxicity on human erythrocytes. Conclusion: KW-23 and its combination with fluconazole could be a promising candidate for developing anticandidal agents.
ABSTRACT
BACKGROUND: The role of pharmacists has recently expanded, necessitating enhanced competencies. This requires pharmacists' participation in continuing education initiatives. This study aims to explore attitudes, motivations, opportunities, and challenges of pharmacists in a country in the middle east, towards continuous professional development. METHODS: A cross-sectional observational close-ended questions study was conducted in Jordan between September and October 2021, and enrolled 309 pharmacists, the tool was developed by the research team and experts in the field to evaluate the continuous professional development perception among pharmacists. The research was approved by the Ethics and Research Committee in an area hospital and a University. RESULTS: The majority of participants had confidence that continuous professional development prepares pharmacists for practical development, believed that it enhances the status of the profession with other health care professionals as well as with the public, and felt confident that it meets their needs (> 98%). Most of the participants agreed that job restrictions (91%) and lack of time (83%) were the major barriers to participation in continuous professional development. The motivation was positively correlated with attitudes (R = 0.551, P < .001). However, barriers were not significantly correlated with either attitudes or motivations. CONCLUSION: Our findings emphasize the positive attitude of pharmacists towards continuous professional development. Identified barriers to continuous professional development participation included job constraints and lack of time. The study highlights the need for policies and procedures that address these issues before the implementation of mandatory continuous professional development programs for pharmacists.

BACKGROUND: Health care providers including pharmacists are often on the first line when dealing with COVID -19; they can be under threat of contracting and spreading the disease. We aimed to assess and compare their knowledge of hand sanitization during COVID-19 pandemic to improve quality of care. METHODS: A cross-sectional study was conducted in Jordan, on healthcare providers in different settings from 27 October till 3 December 2020, using a pre-validated electronic questionnaire. Participants (n = 523) were healthcare providers practicing in different settings. Descriptive and association statistical analyses were produced on the data using SPSS 26. Chi square was used for the categorical variables, and One way ANOVA was used on the continuous and categorical variables. RESULTS: A significant difference was recorded in total knowledge mean according to gender (59.78 vs 61.79 p = 0.030) in favor of men, and between pharmacists and other healthcare providers in favor of the latter (59.22 vs 61.45, p = 0.02). No significant difference was generally noticed between those who attended hand hygiene training and those who did not. CONCLUSION: Healthcare providers' knowledge of hand hygiene was generally good among participants, regardless of training and it was possibly increased because of fear of COVID-19 infection. Physicians were the most knowledgeable in regard of hand hygiene while pharmacists were the least among healthcare providers. Thus, structured, more frequent, and tailored training on hand sanitization in addition to new educational strategies are recommended for healthcare providers, in particular, pharmacists for better quality of care especially in pandemics.

Minimizing antibiotic resistance is a key motivation strategy in designing and developing new and combination therapy. In this study, a combination of the antibiotics (cefixime, levofloxacin and gentamicin) with Lysobacter enzymogenes (L. enzymogenes) bioactive proteases present in the cell- free supernatant (CFS) have been investigated against the Gram-positive methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant Staphylococcus aureus (MRSA) and the Gram-negative Escherichia coli (E. coli O157:H7). Results indicated that L. enzymogenes CFS had maximum proteolytic activity after 11 days of incubation and higher growth inhibitory properties against MSSA and MRSA compared to E. coli (O157:H7). The combination of L. enzymogenes CFS with cefixime, gentamicin and levofloxacin at sub-MIC levels, has potentiated their bacterial inhibition capacity. Interestingly, combining cefixime with L. enzymogenes CFS restored its antibacterial activity against MRSA. The MTT assay revealed that L. enzymogenes CFS has no significant reduction in human normal skin fibroblast (CCD-1064SK) cell viability. In conclusion, L. enzymogenes bioactive proteases are natural potentiators for antimicrobials with different bacterial targets including cefixime, gentamicin and levofloxacin representing the beginning of a modern and efficient era in the battle against multidrug-resistant pathogens.

BACKGROUND: The use of cosmetic products is growing in dominance in the Arab population, making it essential to measure its effects on users. The production of cosmetics has been largely driven by consumerism and a bid to keep abreast with the latest trends in the beauty industry with less attention on how the users' quality of life (QoL) is affected. AIMS: This study aims to investigate the effect of cosmetic products on users' quality of life in eight Arab countries. METHODS: A cross-sectional study was carried out using an online data collection approach. A validated and specialist instrument tool called BeautyQoL, which consists of five domains and a total of 52 questions, was distributed to a sample of 2219 cosmetic users. Descriptive and inferential statistical analysis was done using SPSS® version 26.0. RESULTS: The mean age of participants was 34 ± 11.25 years, and more women were represented in the sample (71%) than men. The majority of respondents had oily skin type (39.6%) and tan skin tone (30.4%). QoL through cosmetic use is computed with a mean score of 51 out of 100. The users' mean score satisfaction from cosmetic use is centred on attractiveness (56.1), followed by self-confidence (51.8). Cosmetics have a statistically significant effect on participants who are young adults, women, single, and employed with high income. As the respondents' skin tone deepens from very fair to dark, the mean score for each domain significantly increases, whereas when skin type changes from very oily to dry, the mean score for each domain decreases. CONCLUSION: The effect of cosmetics on the users' QoL is limited, contrary to the narrative commonly portrayed in cosmetics' advertisements. Therefore, the use of cosmetics among the Arab population should be from an informed perspective of their specific needs instead of conforming to the viral trends pedaled by influencers and bloggers on social media, which might be irrelevant for them.

Factors associated with antibiotic use, resistance and safety have been well recognized worldwide in the literature. Nevertheless, only few studies have been conducted in Jordan in this area. The aim of this study was to assess knowledge, behavior and attitude toward antibiotics use among adult Jordanians. The study represents a cross sectional survey using an interviewer administered questionnaire. Data collected from a random sample of 1141 adult Jordanians, recruited at different settings, regarding their knowledge about the effectiveness of, resistance toward, and self medications with antibiotics against bacterial, viral and parasitic diseases. 67.1% believed that antibiotics treat common cold and cough. 28.1% misused antibiotics as analgesics. 11.9% of females showed inadequate knowledge about the safe use of antibiotics during pregnancy and nursing. 28.5% kept antibiotics at home for emergency use and 55.6% use them as prophylaxis against infections. 49.0% use left-over antibiotics without physicians' consultation while 51.8% use antibiotics based on a relative advice. 22.9% of physicians prescribe antibiotics over the phone and >50.0% routinely prescribe antibiotics to treat common cold symptoms. Our findings indicated that young adults showed unsatisfactory knowledge of proper antibiotic use. Therefore, there is an urge for educational programs using all media means.
ABSTRACT
Background: Bacterial resistance is a challenging limitation in infection treatment. This work evaluates the potential antibacterial activity of conjugation of Tryasine peptide with silver nanoparticles against selected pathogens. Materials and Methods: The peptide Tryasine was produced using three subunits of tryptophan and three lysine amino acids, then its purity was determined by reverse-phase high-performance liquid chromatography. The peptide was confirmed using mass spectrometry and electrospray ionization mass spectrometry. Silver nanoparticles conjugate with Tryasine was synthesized by adding Tryasine-silver nitrate solution in the presence of the reducing agent sodium borohydride. The presence of Tryasine-silver nanoparticles was indicated by the yellow-brown color and was further confirmed through ultraviolet-visible spectrophotometry. The minimum inhibitory and minimum bactericidal concentrations for Tryasine nanoparticles were determined against Staphylococcus aureus, Escherichia coli, methicillin resistant Staphylococcus aureus, and ESBL Escherichia coli using the microdilution method. Toxicity for nanoparticles conjugated with Tryasine was determined using erythrocyte hemolytic assay. Results: Tryasine alone was effective (MIC around 100 and 200 µM) against standard and resistant strains of bacteria used. However, Tryasine-silver nanoparticles were more effective with MICs ranging from 30 to 100 µM depending on the bacterial strain used. Tryasine-silver nanoparticles at concentration of 100 µM only caused 1% hemolysis on human erythrocytes after 30 min of incubation. Conclusions: The findings indicate that Tryasine-silver nanoparticles had good antibacterial activity against pathogenic strains of Gram-positive and Gram-negative bacteria. Additionally, the conjugate showed low hemolytic activity and cytotoxicity. Therefore, conjugation of Tryasine with silver nanoparticles is a promising treatment candidate for bacterial infection with low toxicity.
ABSTRACT
OBJECTIVES: The study aimed to evaluate four selective serotonin reuptake inhibitors (SSRIs) as modifiers of fluconazole activity against resistant strains of Candida glabrata. METHODS: The effect of SSRIs on fluconazole activity was studied using the checkerboard method against C. glabrata strains (CBS 138, CBS 850821, DSY 562, DSY 565, ATCC 22553 and ATCC 90030); fractional inhibitory concentration index (FIC) was calculated and time-kill curve was used for the most prominent combination for further evaluation. RESULTS: All used SSRIs have antifungal activity against the C. glabrata strains tested. A combination of fluconazole with fluoxetine or fluvoxamine showed indifferent effects (fractional inhibitory concentration index [FICI] in all strains >1 but <4), whereas a paroxetine-fluconazole combination showed an additive effect against DSY565 and CBS138, known to express efflux pumps as well as on ATCC strain (0.5 < FIC < 1) with indifferent effect on other strains used. The most promising combination was that of fluconazole with sertraline (FICI ≤0.5), where a synergistic effect was observed against all resistant and susceptible dose-dependent strains, including those known to express efflux pumps. This synergistic effect was confirmed by time-kill curve assay against all resistant C. glabrata and ATCC strains with a >2-log10 CFU/mL reduction caused by combination compared with a single active agent of fluconazole after 24 hours of incubation. A sertraline-fluconazole combination produced an additive effect on the reference ATCC strain. CONCLUSION: Our data suggest that blocking active efflux pumps by sertraline may be considered the probable mechanism of synergism with fluconazole. The combination of sertraline with fluconazole could be a promising remedy for treatment of infections caused by resistant C. glabrata.

This study assesses Jordanian community pharmacists' readiness and willingness to deliver vaccination services in their practice sites. Between February and April 2021, a self-administered online questionnaire was distributed via social media, WhatsApp messages, and personal communication. The questionnaire targeted practicing community pharmacies. Descriptive and inferential data analysis was carried out. A total of 403 community pharmacists participated in the study. Almost 146 (36%) community pharmacists reported vaccinating patients in their practice sites. However, readiness assessment revealed that only 54 (13.4%) pharmacists received the required training and qualifications. Moreover, 33 (8.2%) study participants worked in adequately equipped and designed community pharmacies. Overall, surveyed participants held positive attitudes toward their involvement in vaccination services: 260 (64.5%) pharmacists were willing to vaccinate patients, and 227 (65.0%) out of unready, unqualified, participants were willing to get needed training and qualifications. According to study participants, regulatory and professional bodies (Ministry of Health, Jordan Pharmacists Association) are influential in supporting pharmacist-vaccinators. Among the investigated factors, organizational structure and employment status were significantly associated with pharmacists' readiness to deliver vaccination. This study revealed that further work is needed to increase pharmacists' and pharmacies' readiness to deliver vaccination services and that regulators should follow a more active approach in highlighting the importance of training and the impact of training in patients' safety and satisfaction.

COVID-19 infection is a global pandemic health emergency. This contagious disease was caused by the Severe Acute Respiratory Syndrome Coronavirus2 (SARSCoV-2) which is mutating over time. In 2021, the Delta variant became the most dominant transmissible form. During the crisis, human practice and knowledge were critical in the overall efforts to encompass the outbreak. A cross-sectional, web-based approach was conducted among adults in Jordan to quantify knowledge, attitude, and practices towards SARS-CoV-2 (Delta variant). This research was carried out between 15th April and 15th of May 2021. The study questionnaire consisted of four sections including the participant's demographics, knowledge, practices and attitude. Comparative evaluation of responses was accomplished using a scoring system. Respondents who scored above the mean score (60%) on the item measured were categorized as knowledgeable, having a positive attitude, and good practices. Participants were allocated to one of the three groups; medical, non-medical and others (unemployed and housewives). Data collected was analyzed using Statistical Package for Social Sciences (SPSS) version 23.0 software. A variance test to assess the statistical difference between groups was used. Pearson's chi-squared test was applied to compare the variables and identify significant predictors. Of the participants, 308 (66%) were in the age group of 18-25yrs, 392 (84.1%) females, 120 (25.8%) employed and 346 (74.2%) unemployed. The principle source of knowledge was social media (291, 62.4%). Interestingly, participants had adequate overall knowledge. The mean knowledge score was 22.6 (± 0.19), 20.6 (± 0.19), and 21.3 (± 0.18) for the medical, the non-medical and the others group, respectively. Also, participants showed a positive attitude and good practices towards SARS-CoV-2 (Delta variant). The mean practice score for medical, the non-medical and the others groups was 7.35 (± 0.25), 7.38 (± 0.24), 7.35 (± 0.24) and the mean attitude score was 10.8 (± 0.16), 9.4 (± 0.21), 9.5 (± 0.22), respectively. The studied groups generally had good knowledge, positive attitudes and good practices about SARS-CoV-2 (Delta variant). This was expected due to the authorities' successful management of the pandemic and the high educational level of the Jordanian society, bearing in mind the economic and social impact of COVID-19 disease.

BACKGROUND: The issue around vaccination of children has brought divergent opinions among the populations across the globe and among the Arab population. There has been a low response rate to the calls for vaccination of children and this is reflective of the sentiments which parents may have towards their children being vaccinated. This study aims to explore the parents' health beliefs, intentions, and strategies towards the COVID-19 vaccine for their children among Arab population. METHODS: A cross-sectional study using an online survey from October to December 2021, was carried out in five Arab countries in the Middle East. A reliable health belief model (HBM) including five domains: severity, susceptibility, benefits, barriers and cues to action, was adopted. Chi-square, Mann-Whitney test, and multivariable logistic regression were performed for data analysis. RESULTS: The survey response rate was 58 % (1154/2000). Only 56 % of Arab parents are intended to vaccinate their children against COVID-19. The mean scores of parental health belief are largely driven by their concern over the vaccine's side effect (p = 0.001) followed by its efficacy, safety (p < 0.001), and scheduling difficulty (p = 0.029). However, strategies that were statistically encouraged parents to vaccinate their children included doctor's recommendation, adequate information being provided, and acceptance of the vaccine by public (p < 0.001). Parents with one child were almost three times most likely to vaccinate their children (OR = 2.660, 95 %CI = 1.572-4.504, p < 0.001). Parents' desire to vaccinate their children is also influenced by other factors such as job loss owing to COVID-19 and the presence of a health worker in the family. CONCLUSION: Intention of Arab parents to vaccinate their children via COVID-19 vaccine is still limited. Thus, it is essential for health care authorities to avail the information which will debunk the erroneous beliefs which some parents have developed towards the vaccination of children against COVID-19.
