RESUMO

BACKGROUND: Integrating artificial intelligence (AI) into healthcare has raised significant ethical concerns. In pharmacy practice, AI offers promising advances but also poses ethical challenges. METHODS: A cross-sectional study was conducted in countries from the Middle East and North Africa (MENA) region on 501 pharmacy professionals. A 12-item online questionnaire assessed ethical concerns related to the adoption of AI in pharmacy practice. Demographic factors associated with ethical concerns were analyzed via SPSS v.27 software using appropriate statistical tests. RESULTS: Participants expressed concerns about patient data privacy (58.9%), cybersecurity threats (58.9%), potential job displacement (62.9%), and lack of legal regulation (67.0%). Tech-savviness and basic AI understanding were correlated with higher concern scores (p < 0.001). Ethical implications include the need for informed consent, beneficence, justice, and transparency in the use of AI. CONCLUSION: The findings emphasize the importance of ethical guidelines, education, and patient autonomy in adopting AI. Collaboration, data privacy, and equitable access are crucial to the responsible use of AI in pharmacy practice.

RESUMO

Objective: The present study was conducted to assess the perceptions and readiness of pharmacists toward implementing "Telepharmacy" in Jordan. Methods: This was a cross-sectional study that was conducted between April and May 2023. Any licensed community pharmacists practicing in Jordan were considered to be eligible to be included in this study. Pharmacists were approached at their pharmacy store using a convenience sampling method. Logistic regression analysis was utilized to identify predictors affecting pharmacists readiness to implement telepharmacy services. Results: Two hundred eighteen community pharmacists volunteered to participate in this study. Roughly around 42% of the pharmacists (n = 91) reported that they have previously used telepharmacy. More than 70% of the pharmacists believed that telepharmacy decreases the patient's visits to hospitals, private clinics, or pharmacies (n = 165, 75.7%). In addition, more than 65% of the pharmacists expressed their concerns that telepharmacy service may increase pharmacists' workload and commitment (n = 150, 68.8%), and it has a higher error rate for medication dispensing and filling (n = 147, 67.4%). Nearly 70% of the pharmacists (n = 153) expressed their readiness to implement telepharmacy. Regression analysis showed that pharmacists who had previous experience in using telepharmacy service and those who showed more positive perception toward telepharmacy showed significantly higher readiness to implement telepharmacy service (p < 0.001 for both). Conclusions: The utilization of telepharmacy by community pharmacists in Jordan is still limited. The adaption of telepharmacy faces many challenges, including a negative attitude from the pharmacist, financial reimbursement, training, regulations, and competency in and access to efficient technology.

RESUMO

Prostate cancer (PCa) is a significant global contributor to mortality, predominantly affecting males aged 65 and above. The field of omics has recently gained traction due to its capacity to provide profound insights into the biochemical mechanisms underlying conditions like prostate cancer. This involves the identification and quantification of low-molecular-weight metabolites and proteins acting as crucial biochemical signals for early detection, therapy assessment, and target identification. A spectrum of analytical methods is employed to discern and measure these molecules, revealing their altered biological pathways within diseased contexts. Metabolomics and proteomics generate refined data subjected to detailed statistical analysis through sophisticated software, yielding substantive insights. This review aims to underscore the major contributions of multi-omics to PCa research, covering its core principles, its role in tumor biology characterization, biomarker discovery, prognostic studies, various analytical technologies such as mass spectrometry and Nuclear Magnetic Resonance, data processing, and recent clinical applications made possible by an integrative "omics" approach. This approach seeks to address the challenges associated with current PCa treatments. Hence, our research endeavors to demonstrate the valuable applications of these potent tools in investigations, offering significant potential for understanding the complex biochemical environment of prostate cancer and advancing tailored therapeutic approaches for further development.

RESUMO

This cross-sectional study aimed to evaluate public perception, satisfaction, expectations, and barriers to utilize the community pharmacy services. A validated self-reported online survey was distributed on 681 individuals in different regions across Jordan. The mean age of the participants was 29 (±10) years. The most reported reason for choosing a particular community pharmacy was its closure to home or workplace (79.1%), while the main reason for visiting a community pharmacy was to obtain over the counter medications (66.2%). The participants showed good perception, satisfaction, and expectations of community pharmacy services. However, several barriers were identified, including higher participants' trust in physicians when compared to pharmacists (63.1%), and lack of privacy in the pharmacy (45.7%). Community pharmacists should participate in successful education and training programs in order to raise the quality of the provided services, meet patient requirements, and re-establish consumer confidence in community pharmacists.

RESUMO

This study investigated parental attitudes toward childhood vaccination in Jordan, focusing on acceptance, concerns, and perceptions. A cross-sectional survey conducted from January to February 2024 included 939 parents. Findings indicated that 85.4% (n = 802) of respondents received the COVID-19 vaccine, while only 25% (n = 229) vaccinated their children. Concerns regarding vaccine safety and efficacy were prevalent, with 63.9% (n = 600) expressing worries about side effects and 46.9% (n = 440) trusting immunization programs. Post-pandemic, 34% (n = 319) reported a more negative attitude. Logistic regression showed parents not vaccinating their children against COVID-19 were significantly less likely to exhibit positive attitudes toward childhood vaccination (OR = 0.412, p < 0.001). Older participants were more inclined toward negativity post-pandemic (OR = 1.031, p = 0.007). In conclusion, parental attitudes shifted post-COVID-19, reflecting hesitancy and decreased trust. Addressing concerns and restoring confidence are crucial, especially for children's health. Education through healthcare providers and dispelling social media misinformation are essential. Implementing strategies to enhance post-pandemic vaccine acceptance is imperative for preventing outbreaks of vaccine-preventable diseases.

RESUMO

OBJECTIVES: This study aims to evaluate healthcare providers' awareness and experience with anabolic androgenic steroid (AAS) use among gym users in Jordan and their role in mitigating AAS misuse. METHODS: A cross-sectional study was conducted between November 2022 and Feb 2023. During the study period, 158 physicians involved in prescribing AAS or treating adverse effects associated with these agents were invited to participate. A questionnaire was created and uploaded on Google Forms and distributed through social media platforms to reach physicians from different medical subspecialties. RESULTS: Of the 158 physicians surveyed, 30.4% were general practitioners, and 63.3% reported having formal education about the risks of bodybuilding with AAS. Among the participants, 48.7% had encountered gym users who were using AAS, with the main reason for referral being the management of side effects associated with AAS use. The median knowledge score regarding AAS and their complications was 10.0 out of 14 (IQR = 7.0), indicating adequate knowledge about most AAS side effects. Around 46% of the physicians (n = 73, 46.2%) believed that gym users might struggle to disclose AAS because they lack trust in them. Finally, the most common advice to gym users was informing them about the health-associated consequences of AAS use, with 92.2% of physicians providing this advice. CONCLUSION: Although healthcare professionals in Jordan had adequate knowledge about AAS, they needed more to make them confident in dealing with AAS use. This highlights the necessity for specialized teaching and training programs to enhance their knowledge and skills in providing accurate information to AAS users.

RESUMO

Nedaplatin is a chemotherapeutic agent used widely in cancer therapy. Nedaplatin has been shown to cause DNA damage to cells via the induction of oxidative stress. Vitamin E (Vit E) has an anti-mutagenic activity that can protect cells from DNA damaging agents. The objective of this study is to examine the genotoxic and cytotoxic effects of nedaplatin in human cultured lymphocytes. In addition, modulation of such effects by Vit E was also examined. The frequencies of sister chromatid exchange (SCE) and chromosomal aberrations (CAs) were used as an indicator for genotoxicity. The mitotic and proliferative indices were used to examine the cytotoxic effects of nedaplatin. The results showed that nedaplatin significantly elevated SCE and CA frequencies in human lymphocytes (p Ë‚ 0.01). The increases in the frequencies of SCE and CA caused by nedaplatin were lowered by pretreatment treatment with Vit E (p < 0.05). Nedaplatin significantly lowered mitotic index but Vit E pretreatment did not modulate this effect. These results suggest that Vit E has the potential to ameliorate the genotoxicity of nedaplatin in cultured lymphocytes.

RESUMO

Skin cancer, including malignant melanoma (MM) and keratinocyte carcinoma (KC), historically named non-melanoma skin cancers (NMSC), represents the most common type of cancer among the white skin population. Despite decades of clinical research, the incidence rate of melanoma is increasing globally. Therefore, a better understanding of disease pathogenesis and resistance mechanisms is considered vital to accomplish early diagnosis and satisfactory control. The "Omics" field has recently gained attention, as it can help in identifying and exploring metabolites and metabolic pathways that assist cancer cells in proliferation, which can be further utilized to improve the diagnosis and treatment of skin cancer. Although skin tissues contain diverse metabolic enzymes, it remains challenging to fully characterize these metabolites. Metabolomics is a powerful omics technique that allows us to measure and compare a vast array of metabolites in a biological sample. This technology enables us to study the dermal metabolic effects and get a clear explanation of the pathogenesis of skin diseases. The purpose of this literature review is to illustrate how metabolomics technology can be used to evaluate the metabolic profile of human skin cancer, using a variety of analytical platforms including gas chromatography-mass spectrometry (GC-MS), liquid chromatography-mass spectrometry (LC-MS), and nuclear magnetic resonance (NMR). Data collection has not been based on any analytical method.

RESUMO

Drug-Food Interaction (DFI) can potentially lead to treatment ineffectiveness and adverse health outcomes. This study investigated knowledge and attitude towards DFI and the associated factors. A validated questionnaire was distributed to 2040 participants across Jordan. The participants had moderate knowledge and attitudes regarding DFIs. Regression results revealed that male gender, lower education level, not working in the healthcare sector, and utilizing non-scientific sources of information about DFIs were associated with lower knowledge about DFI. Furthermore, male gender, being unmarried, having a low or moderate education level, not working in the healthcare sector, not having a family member with chronic disease, and having low knowledge of DFI were significantly associated with negative attitudes towards DFIs. Future health education programs should emphasize using reliable scientific sources to enhance awareness about DFIs'. Additionally, healthcare professionals should counsel patients on avoiding DFIs and provide guidance accordingly.

RESUMO

Background: The COVID-19 pandemic was detrimental to lifestyle and behavior. In this investigation, changes in reading habits during the pandemic were examined. Methods: The study is cross-sectional and survey-based. 1844 individuals completed an online survey about sociodemographic and reading habits during COVID-19. Multinomial logistic regression was used to examine the relationship between the study variables. Results: Most of the participants were active readers (71.5%-83.2%). Fewer (13.8-18.0%) reported a decrease in reading, while about half reported a no change, and 1/3rd reported an increase. Changes in reading habits were related to age, education, job type, and income. Conclusion: About half of the participants during the pandemic reported a change in reading habits. Interventions to further enhance reading among people during the pandemic might help ameliorate the negative impacts of the pandemic.

RESUMO

Background: Artificial intelligence (AI) is the capacity of machines to perform tasks that ordinarily require human intelligence. AI can be utilized in various pharmaceutical applications with less time and cost. Objectives: To evaluate community pharmacists' willingness and attitudes towards the adoption of AI technology at pharmacy settings, and the barriers that hinder AI implementation. Methods: This cross-sectional study was conducted among community pharmacists in Jordan using an online-based questionnaire. In addition to socio-demographics, the survey assessed pharmacists' willingness, attitudes, and barriers to AI adoption in pharmacy. Binary logistic regression was conducted to find the variables that are independently associated with willingness and attitude towards AI implementation. Results: The present study enrolled 401 pharmacist participants. The median age was 30 (29-33) years. Most of the pharmacists were females (66.6%), had bachelor's degree of pharmacy (56.1%), had low-income (54.6%), and had one to five years of experience (35.9%). The pharmacists showed good willingness and attitude towards AI implementation at pharmacy (n = 401). The most common barriers to AI were lack of AI-related software and hardware (79.2%), the need for human supervision (76.4%), and the high running cost of AI (74.6%). Longer weekly working hours (attitude: OR = 1.072, 95% C.I (1.040-1.104), P < 0.001, willingness: OR = 1.069, 95% Cl. 1.039-1.009, P-value = 0.011), and higher knowledge of AI applications (attitude: OR = 1.697, 95%Cl (1.327-2.170), willingness: OR = 1.790, 95%Cl. (1.396-2.297), P-value < 0.001 for both) were significantly associated with better willingness and attitude towards AI, whereas greater years of experience (OR = 20.859, 95% Cl (5.241-83.017), P-value < 0.001) were associated with higher willingness. In contrast, pharmacists with high income (OR = 0.382, 95% Cl. (0.183-0.795), P-value = 0.010), and those with<10 visitors (OR = 0.172, 95% Cl. (0.035-0.838), P-value = 0.029) or 31-50 visitors daily (OR = 0.392, 95% Cl. (0.162-0.944), P-value = 0.037) had less willingness to adopt AI. Conclusions: Despite the pharmacists' positive willingness and attitudes toward AI, several barriers were identified, highlighting the importance of providing educational and training programs to improve pharmacists' knowledge of AI, as well as ensuring adequate funding support to overcome the issue of AI high operating costs.

RESUMO

Introduction: Drug-related problems (DRPs) are events or circumstances involving drug therapy that actually or potentially interferes with desired health outcomes. Objectives: To assess community pharmacists' knowledge and practice regarding DRP-reduction services, as well as the barriers and factors associated with decreased provision of these services. Methods: This cross-sectional study utilized a validated questionnaire to assess pharmacists' knowledge, practice, and barriers to the provision of DRP-reduction services in the community pharmacy setting. Binary regression model was used to assess the variables associated with the practice of DRP-reduction services. Results: A total of 412 pharmacists participated in the study. The pharmacists demonstrated strong knowledge but inadequate practice of DRP-reduction services. The most reported DRPs were inappropriate combination of drugs, or drugs and herbal medications, or drugs and dietary supplements (52.4%), patients' inability to understand instructions properly (46.1%), inappropriate drug according to guidelines (43.7%), and too high dose (40.3%). The most common barriers to these services were increased workload (60.5%), limited time (53.2%), and lack of good communication skills (49.8%). The presence of a counselling area in the pharmacy increased the practice of DRP-reduction services (OR: 3.532, 95%Cl: 2.010-5.590, P < 0.001), while increased weekly working hours (OR: 0.966, 95%Cl: 0.947-0.986), P < 0.01) and serving < 10 patients daily (OR = 0.208, 95%Cl: 0.072-0.601, P < 0.01) decreased it. Conclusions: Community pharmacists' practice of DRP-reduction services showed a scope for improvement. Future pharmaceutical care initiatives should increase the number of personnel working in the pharmacy and provide them with opportunities for continued education and training in order to improve the provision of DRP services and optimize patients' outcomes.

RESUMO

Background: The aim of the study was to examine changes in the frequency of respiratory diseases during the COVID-19 pandemic and to correlate the changes with nonpharmacological interventions for overcoming the pandemic. In addition, the study explored the predictors of adherence to nonpharmacological interventions among the Jordanian public. Method: The study is survey-based and self-reported, using convenient sampling. The study was conducted during October-November of 2021. Results: The study included 1714 participants. About one-quarter of participants reported decreases in the incidence of cold (21.9%), influenza (24.7%), respiratory infections other than cold and influenza (23.3%), tonsillitis (23.0%), and oral ulcers (23.5%). On the other hand, the majority reported no change in the incidence of the above infections (62.0-64.4%). Adherence of the sample to nonpharmacological interventions of COVID-19 was moderate. The percentages of people who always wear a mask, follow social distancing, and use sanitizing procedures were 47.1%, 37.8%, and 68.8% respectively. ANOVA test showed a significant correlation between the incidence of respiratory/oral infections and adherence to nonpharmacological interventions. The multiple regression test showed that people who followed COVID-19 news, have children, have a job, and being married were more adhered to nonpharmacological measures compared to others. Conclusion: Implementation of nonpharmacological interventions used to overcome the COVID-19 pandemic can be applied to reduce other respiratory infections during their peak seasons.

RESUMO

The outbreak of the COVID-19 pandemic puts a great strain on the healthcare system, as the national and global infection rates increased rapidly. Efforts were devoted to minimizing the effects of the spreading pandemic without overwhelming the already stretched healthcare system. The study objective was to establish how coronavirus lockdown was affecting chronic disease care among pediatric patients admitted to hospitals in developing countries. For that purpose, a cross-sectional survey of registered pediatricians was carried out. Findings showed that the mortality rate from COVID-19 in children seemed to be low. However, children with chronic illnesses were likely to be gravely affected by the disturbance of repetitive healthcare services. About 79% of pediatricians treated a child with a chronic condition during the lockdown. Furthermore, 15% of patients with chronic diseases visiting pediatricians exhibited uncontrolled emerging complications. In addition, 9% of pediatricians reported one to five fatalities among children under their care due to delay or lack of appropriate medical care in the period of the lockdown. Residents (48.9%) reported a significantly (p < 0.001) higher proportion of providing face-to-face services compared with consultants (17.9%) and specialists (13.6%). In conclusion, the care of chronically ill children should be taken into consideration when implementing lockdown and/or social distancing, thus minimizing the negative effects of lockdown and/or social distancing on children with chronic diseases.

RESUMO

Sex selection is becoming a more common practice in the society and worldwide. The current study aimed to examine the perceptions about sex selection options and possible association with sociodemographic factors and relevant characteristics. The study was a cross-sectional survey of adults in Jordan in January and February 2020 using a self-administered questionnaire. Results showed that 40.1% of respondents preferred male gender when having a child, 22.4% of respondents preferred the male gender when having a child, even if they have had children of both genders, and 71.3% preferred having children from both genders. On the other hand, 58.8% of participants preferred a male gender when there is one chance to conceive via assisted reproduction technologies. Also, among participants, 66% thought that sex selection is religiously acceptable, yet 78.0% did not support of the sex selection idea. The above factors were significantly associated with several sociodemographic variables such as gender, marital status, education, career, and place of residence, but not income. In conclusion, the current study shed a light on preferences towards sex selection in a large cohort to better understand the perception and attitude of the population towards this practice.

RESUMO

The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has captivated the globe's attention since its emergence in 2019. This highly infectious, spreadable, and dangerous pathogen has caused health, social, and economic crises. Therefore, a worldwide collaborative effort was made to find an efficient strategy to overcome and develop vaccines. The new vaccines provide an effective immune response that safeguards the community from the virus' severity. WHO has approved nine vaccines for emergency use based on safety and efficacy data collected from various conducted clinical trials. Herein, we review the safety and effectiveness of the WHO-approved COVID-19 vaccines and associated immune responses, and their impact on improving the public's health. Several immunological studies have demonstrated that vaccination dramatically enhances the immune response and reduces the likelihood of future infections in previously infected individuals. However, the type of vaccination and individual health status can significantly affect immune responses. Exposure of healthy individuals to adenovirus vectors or mRNA vaccines causes the early production of antibodies from B and T cells. On the other hand, unhealthy individuals were more likely to experience harmful events due to relapses in their existing conditions. Taken together, aligning with the proper vaccination to a patient's case can result in better outcomes.

RESUMO

Glioblastoma (GB) is a primary malignancy of the central nervous system that is classified by the WHO as a grade IV astrocytoma. Despite decades of research, several aspects about the biology of GB are still unclear. Its pathogenesis and resistance mechanisms are poorly understood, and methods to optimize patient diagnosis and prognosis remain a bottle neck owing to the heterogeneity of the malignancy. The field of omics has recently gained traction, as it can aid in understanding the dynamic spatiotemporal regulatory network of enzymes and metabolites that allows cancer cells to adjust to their surroundings to promote tumor development. In combination with other omics techniques, proteomic and metabolomic investigations, which are a potent means for examining a variety of metabolic enzymes as well as intermediate metabolites, might offer crucial information in this area. Therefore, this review intends to stress the major contribution these tools have made in GB clinical and preclinical research and highlights the crucial impacts made by the integrative "omics" approach in reducing some of the therapeutic challenges associated with GB research and treatment. Thus, our study can purvey the use of these powerful tools in research by serving as a hub that particularly summarizes studies employing metabolomics and proteomics in the realm of GB diagnosis, treatment, and prognosis.

RESUMO

Cancer of the central nervous system (CNS) is ranked as the 19th most prevalent form of the disease in 2020. This study aims to identify candidate biomarkers and metabolic pathways affected by paclitaxel and etoposide, which serve as potential treatments for glioblastoma, and are linked to the pathogenesis of glioblastoma. We utilized an untargeted metabolomics approach using the highly sensitive ultra-high-performance liquid chromatography-electrospray ionization quadrupole time-of-flight mass spectrometry (UHPLC-ESI-QTOF-MS) for identification. In this study, 92 and 94 metabolites in U87 and U373 cell lines were profiled, respectively. The produced metabolites were then analyzed utilizing t-tests, volcano plots, and enrichment analysis modules. Our analysis revealed distinct metabolites to be significantly dysregulated (nutriacholic acid, L-phenylalanine, L-arginine, guanosine, ADP, hypoxanthine, and guanine), and to a lesser extent, mevalonic acid in paclitaxel and/or etoposide treated cells. Furthermore, both urea and citric acid cycles, and metabolism of polyamines and amino acids (aspartate, arginine, and proline) were significantly enriched. These findings can be used to create a map that can be utilized to assess the antitumor effect of paclitaxel and/or etoposide within the studied cancer cells.

RESUMO

Hepatocellular carcinoma (HCC) is the second prominent cause of cancer-associated death worldwide. Usually, HCC is diagnosed in advanced stages, wherein sorafenib, a multiple target tyrosine kinase inhibitor, is used as the first line of treatment. Unfortunately, resistance to sorafenib is usually encountered within six months of treatment. Therefore, there is a critical need to identify the underlying reasons for drug resistance. In the present study, we investigated the proteomic and metabolomics alterations accompanying sorafenib resistance in hepatocellular carcinoma Hep3B cells by employing ultra-high-performance liquid chromatography quadrupole time of flight mass spectrometry (UHPLC-QTOF-MS). The Bruker Human Metabolome Database (HMDB) library was used to identify the differentially abundant metabolites through MetaboScape 4.0 software (Bruker). For protein annotation and identification, the Uniprot proteome for Homo sapiens (Human) database was utilized through MaxQuant. The results revealed that 27 metabolites and 18 proteins were significantly dysregulated due to sorafenib resistance in Hep3B cells compared to the parental phenotype. D-alanine, L-proline, o-tyrosine, succinic acid and phosphatidylcholine (PC, 16:0/16:0) were among the significantly altered metabolites. Ubiquitin carboxyl-terminal hydrolase isozyme L1, mitochondrial superoxide dismutase, UDP-glucose-6-dehydrogenase, sorbitol dehydrogenase and calpain small subunit 1 were among the significantly altered proteins. The findings revealed that resistant Hep3B cells demonstrated significant alterations in amino acid and nucleotide metabolic pathways, energy production pathways and other pathways related to cancer aggressiveness, such as migration, proliferation and drug-resistance. Joint pathway enrichment analysis unveiled unique pathways, including the antifolate resistance pathway and other important pathways that maintain cancer cells' survival, growth, and proliferation. Collectively, the results identified potential biomarkers for sorafenib-resistant HCC and gave insights into their role in chemotherapeutic drug resistance, cancer initiation, progression and aggressiveness, which may contribute to better prognosis and chemotherapeutic outcomes.

RESUMO

AIM: This study aimed to explore healthcare providers' (HCP) stigmatization from patients during the COVID-19 outbreak in Jordan. METHOD: A cross-sectional design was used. Data collection was conducted between May and July 2021. The research questionnaire included demographic information about participants and multiple statements that reflect stigma of participants toward HCPs. Regression analysis was conducted to assess the association between stigma and explanatory variables. RESULTS: A total of 777 surveys were included in the study. Many people show high stigma toward HCPs during COVID-19 pandemic. Various factors including hearing news all time (p<.001), having children (p<.024), and smoking (p<.001) were significant in prediction stigma toward HCPs. CONCLUSION: This one of few studies conducted in Jordan regarding the stigma toward HCP from other people with chronic diseases. Our study found that many people showed some stigma toward HCP during COVID-19. Stigmatization of HCP related to a pandemic is a lesson most people have not learned. It is not enough to cheer HCPs. A clear, sensible public education campaign about the public's risks by interacting with HCP is necessary.
