RESUMEN

BACKGROUND: Excessive use of mobile phones leading to development of symptoms suggestive of dependence syndrome with teenagers are far more likely to become dependent on mobile phones as compared to adults. COVID-19 pandemic has had an impact on the mental health of several groups in society, especially university students. This study aimed to explore the prevalence of mobile phone dependence among university students and its associated factors. METHODS: Between September 2021 and January 2022, a cross-sectional study was conducted at universities in Jordan, Lebanon, Egypt, Bahrain, and Saudi Arabia utilizing an online and paper-based self-administered questionnaire. We employed a previously developed questionnaire by Aggarwal et al. RESULTS: A total of 5,720 university students were involved in this study (Egypt = 2813, Saudi Arabia = 1509, Jordan = 766, Lebanon = 432, and Bahrain = 200). The mean estimated daily time spent on using mobile phone was 186.4 (94.4) minutes. The highest mobile dependence score was observed for the university students from Egypt and the lowest mobile dependence score was observed for the university students from Lebanon. The most common dependence criteria across the study sample was impaired control (55.6%) and the least common one was harmful use (25.1%). Females and those reported having anxiety problem or using a treatment for anxiety were at higher risk of developing mobile phone dependence by 15% and 75%, respectively. CONCLUSION: Mobile phone dependence is common among university students in Arab countries in the Middle East region. Future studies exploring useful interventions to decrease mobile phone dependence are warranted.

RESUMEN

BACKGROUND: Pharmaceutical companies spend more than one-third of their sales revenue on marketing and promotion directed toward healthcare professionals. There has been a focus on the relationship between healthcare professionals and the pharmaceutical industry in recent years. This study aims to explore the attitude toward and acceptability of medical promotional tools and their influence on physicians' prescribing practices in Jordan and Iraq. METHODS: A cross-sectional survey study was conducted to explore the influence of visits by medical representatives (MRs) and medical promotions on physicians' prescribing practices between June and October 2020 in Jordan and Iraq. Previously validated questionnaires were used. RESULTS: A total of 801 physicians completed the questionnaires. Face-to-face visits, followed by the dispensing of medical samples, were the two most common promotional methods used by MRs. 48% of participating physicians reported that they would accept the promotional marketing tools offered to them. MRs focused on the key selling points of their product during medical promotions, and 39.6% of the physicians reported that MRs had a negative attitude toward their competitors' products. 69.9% of the physicians reported that they would change their practice after participating in conferences or meetings. CONCLUSION: Medical promotional tools have a clear influence on physicians' prescribing practices in Jordan and Iraq. Therefore, medical promotion should be controlled and guided by clear and country-specific ethical guidelines. This will ensure safe medical promotion to physicians and optimise the healthcare practices provided to patients.

RESUMEN

BACKGROUND: Pharmacists are considered to be important sources of drug information (DI) for patients and other healthcare providers. This study aims to examine the characteristics of DI utilization for practicing pharmacists in Jordan and identify the main barriers that impede their ability to utilize them. METHOD: A cross-sectional study using an online survey was conducted in Jordan between the 27th of November 2020 and 18th of January 2021. Our questionnaire was constructed to explore pharmacists' utilization patterns of DI resources, the types of DI resources they use and barriers impeding them. RESULTS: A total of 1875 pharmacists participated in this study. Only one-fifth of the participating pharmacists reported that they referred to DI databases. The most commonly reported databases/websites were Drugs.com, Jordan FDA, and Medscape. The most commonly reported paper-based resources were Drugs in Jordan, Step up pharmacy, and British Pharmacopeia. The most commonly used mobile applications were Drugs.com, Medscape and Lexicomp. 44% of the pharmacists reported that they use DI resources fewer than five times per week and more than half of them (60.7%, n = 1138) reported that the day-shift was the shift that allowed them more time to use DI resources. Lack of time was the most common barrier (53.2%) that restricted the ability of pharmacists to use DI resources. CONCLUSION: Using electronic resources is still deficient and far from optimum and interventions to improve the pharmacists' utilization of electronic drug databases are required. Universities and various pharmaceutical bodies are advised to train pharmacists on using DI databases.

RESUMEN

Excess cardiac iron levels are associated with cardiac damage and can result in increased morbidity and mortality. Here, we hypothesize that elevations in tissue iron can activate caspase-dependent signaling, which leads to increased cardiac apoptosis and fibrosis, and that these alterations can be attenuated by iron chelation. Using an iron-overloaded gerbil model, we show that increased cardiac iron is associated with reduced activation of Akt (Ser473 and Thr308), diminished phosphorylation of the proapoptotic regulator Bad (Ser136), and an increased Bax/Bcl-2 ratio. These iron-overload-induced alterations in Akt/Bad phosphorylation and Bax/Bcl-2 ratio were coupled with increased activation of the downstream caspase-9 (40/38- and 17-kDa fragments) and apoptosis executioner caspase-3 (19- and 17-kDa fragments), which were accompanied by evidence of elevated cytoskeletal α-fodrin cleavage (150- and 120-kDa fragments), discontinuity of myocardial membrane dystrophin immunoreactivity, increases in the number of terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL)-positive cells (nucleic DNA fragmentation), and cardiac fibrosis. We demonstrate that the administration of deferasirox, a tridentate iron chelator, is associated with diminished tissue iron deposition, attenuated activation of caspases, reduced α-fodrin cleavage, improved membrane integrity, decreased TUNEL reactivity, and attenuated cardiac fibrosis. These results suggest that the activation of caspase-dependent signaling may play a role in the development of iron-induced cardiac apoptosis and fibrosis, and deferasirox, via a reduction in cardiac tissue iron levels, may be useful for decreasing the extent of iron-induced cardiac damage.

RESUMEN

BACKGROUND: The emergence of COVID-19 global pandemic coupled with high transmission rate and mortality has created an unprecedented state of emergency worldwide. This global situation may have a negative impact on the psychological well-being of individuals which in turn impacts individuals' performance. This study aims to explore the prevalence of depression and anxiety among the GP, HCPs, and USs during COVID-19 outbreak, and to identify key population(s) who might need psychological intervention. METHODS: A cross-sectional study using an online survey was conducted in Jordan between 22 and 28 March 2020 to explore the mental health status (depression and anxiety) of the general population, healthcare professionals, and university students during the COVID-19 outbreak. The Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) were used to assess depression and anxiety among the study participants. Logistic regression analysis was used to identify predictors of depression and anxiety. RESULTS: The prevalence of depression and anxiety among the entire study participants was 23.8% and 13.1%, respectively. Anxiety was most prevalent across university students 21.5%, followed by healthcare professionals 11.3%, and general population 8.8%. Females among healthcare professionals and university students, divorced healthcare professionals, pulmonologists, and university students with history of chronic disease were at higher risk of developing depression. Females, divorced participants among the general population, and university students with history of chronic disease and those with high income (≥1,500 JD) were at higher risk of developing anxiety. CONCLUSIONS: During outbreaks, individuals are put under extreme stressful condition resulting in higher risk of developing anxiety and depression particularly for students and healthcare professionals. Policymakers and mental healthcare providers are advised to provide further mental support to these vulnerable groups during this pandemic.

RESUMEN

Iron-induced cardiovascular disease is the leading cause of death in iron-overloaded patients. Deferasirox is a novel, once daily oral iron chelator that was recently approved for the treatment of transfusional iron overload. Here, we investigate whether deferasirox is capable of removing cardiac iron and improving iron-induced pathogenesis of the heart using the iron overload gerbil model. Animals were randomly divided into three groups: control, iron overload, and iron overload + deferasirox treatment. Iron-dextran was given 100 mg/kg per 5 days i.p for 10 weeks. Deferasirox treatment was taken post iron loading and was given at 100 mg/kg/day p.o for 1 or 3 months. Cardiac iron concentration was determined by inductively coupled plasma atomic emission spectroscopy. Compared with the untreated group, deferasirox treatment for 1 and 3 months decreased cardiac iron concentration 17.1% (P = 0.159) and 23.5% (P < 0.05), respectively. These treatment-associated reductions in cardiac iron were paralleled by decreases in tissue ferritin expression of 20% and 38% at 1 and 3 months, respectively (P < 0.05). Using oxyblot analysis and hydroethidine fluorescence, we showed that deferasirox significantly reduces cardiac protein oxidation and superoxide abundance by 36 and 47.1%, respectively (P < 0.05). Iron-induced increase in oxidative stress was also associated with increased phosphorylation of ERK-, p38-, and JNK-mitogen-activated protein kinase (MAPK). Interestingly, deferasirox treatment significantly diminished the phosphorylation of all three MAPK subfamilies. These results suggest that deferasirox may confer a cardioprotective effect against iron induced injury.

RESUMEN

OBJECTIVES: To (1) investigate physicians' expectations about community pharmacist's roles and physician attitudes toward collaborative agreements with community pharmacists in West Virginia and (2) determine physicians' perceptions of pharmacists providing medication therapy management (MTM) services. METHODS: A mail survey was conducted for a random sample of 500 physicians practicing in West Virginia. Survey items measured the physicians' perceptions about the roles of pharmacists, their level of comfort with pharmacists providing certain MTM services, and their attitudes toward a collaborative agreement with pharmacists. RESULTS: 102 responses were received, yielding a response rate of 22.1%; 60% of the physicians had a favorable attitude toward supporting collaborative agreement with pharmacists. Physicians were more comfortable with certain areas of MTM services, such as general drug education and the Medicare Part D prescription drug benefit, and they expected pharmacists to identify medication errors and educate the patients about the safe and appropriate use of medications. CONCLUSION: Of the physician respondents, 60% reported a favorable attitude toward collaborative practice agreements, but their attitude toward pharmacists' role in collaborative drug therapy management and pharmacists providing MTM services were not that favorable. Participating physicians may not have consistent expectations regarding pharmacists providing patient care.

RESUMEN

Protein kinases are promising therapeutic targets for cancer therapy. Here, we applied multiple approaches to optimize the potency and selectivity of our reported alloxazine scaffold. Flexible moieties at position 2 of the hetero-tricyclic system were incorporated to fit into the ATP binding site and extend to the adjacent allosteric site and selectively inhibit protein kinases. This design led to potential selective inhibition of ABL1, CDK1/Cyclin A1, FAK, and SRC kinase by 30-59%. Cytotoxicity was improved by ∼50 times for the optimized lead (10b; IC50 = 40 nM) against breast cancer (MCF-7) cells. Many compounds revealed potential cytotoxicity against ovarian (A2780) and colon carcinoma (HCT116) cells of ∼10-30 time improvement (IC50 5-17 nM). The results of the Annexin-V/PI apoptotic assay demonstrated that many compounds induced significantly early (89-146%) and a dramatically late (556-1180%) cell death in comparison to the vehicle control of MCF-7 cells. SAR indicated that 5-deazaalloxazines have a higher selectivity for Abl-1 and FAK kinases than alloxazines. The correlations between GoldScore fitness into FAK and SRC kinases and IC50 against MCF-7 and A2780 cells were considerable (R2: 0.86-0.98).

RESUMEN

Iron-induced cardiovascular disease is the leading cause of death in iron-overloaded patients. Deferasirox is a novel tridentate oral chelator that exhibits a half-life suitable for once-daily dosing; however, little is known regarding the effectiveness of this agent in preventing iron-induced cardiovascular disease. Adult male Mongolian gerbils were randomly divided into 3 groups: control, iron overload, and iron overload followed by deferasirox treatment. Iron-overloaded animals received iron dextran 100 mg/kg intraperitoneally (ip)/5 days for 10 weeks, while deferasirox was given 100 mg/kg per d orally (po) for 9 months post iron loading. Cardiac and aortic iron levels were determined by inductively coupled plasma atomic emission spectrometry. Gerbil electro- and echocardiograms were obtained in anesthetized animals at regular intervals. Compared to control animals, iron concentration was 3.3- and 2.4-fold higher in iron-overloaded heart and aorta, respectively (P < .05). Deferasirox treatment reduced cardiac and aortic iron levels by 32% and 35%, respectively (P < .05). These results were consistent with the decrease in cellular iron deposition observed with Prussian Blue iron staining. Iron-overloaded gerbils were found to exhibit frequent arrhythmias including premature ventricular contractions, supraventricular tachycardia, and recurrent ventricular tachycardia. In addition, echocardiographic assessment demonstrated iron overload-associated increase in left ventricular dimensions including left ventricular posterior wall dimension (LVPWd: 49%), left ventricular internal dimension (LVIDd: 26%), and left ventricular septum thickness (LVSd: 42%). These parameters were significantly reduced with deferasirox treatment (LVPWd: 23%, LVIDd: 24%, and LVSd: 27%). Iron overload was also associated with reduced ejection fraction (EF: by 30%) and fractional shortening (FS: by 23%) in comparison with controls (P < .05). With deferasirox treatment, these values were higher (EF: by 30%, FS: by 28%) compared to iron-overloaded group. These findings suggest that deferasirox may be useful for attenuating iron-induced changes in cardiac structure and function.

RESUMEN

Iron overload is associated with an increased risk of liver complications including fibrosis, cirrhosis, and hepatocellular carcinoma. Deferasirox is a new oral chelator with high iron-binding potency and selectivity. Here we investigate the ability of deferasirox to remove excessive hepatic iron and prevent iron-induced hepatic injury. Adult male Mongolian gerbils were divided into 3 groups (n=5/group)-control, iron overload (100 mg iron-dextran/kg body weight/5 days; intraperitoneal for 10 weeks), and iron overload followed by deferasirox treatment (100 mg deferasirox/kg body weight/d; pulse oral for 1 or 3 months). Compared with the nontreated iron overload group, deferasirox reduced hepatic iron concentration by 44% after 3 months of treatment (P<0.05). Histological analysis of hepatic tissue from the iron overloaded group detected frequent iron deposition, evidence of hepatic damage, and an accumulation of lipid vacuoles. Iron deposition was significantly diminished with deferasirox treatment, and no evidence of lipid accumulation was observed. Immunoblotting demonstrated that iron overload caused approximately 2-fold increase in hepatic ferritin expression (P<0.05), which was 48% lower after 3 months of deferasirox treatment (P<0.05). Deferasirox treatment also was associated with reduced hepatic protein oxidation, superoxide abundance, and cell death. The percentage of terminal deoxynucleotidyl transferase dUTP nick end labeling positive cells in the deferasirox-treated livers was 41% lower than that of iron overloaded group (P<0.05). Similarly, an iron-related increase in the expression of Bax/Bcl2, Bad, and caspase-3 were significantly lower after deferasirox treatment. These findings suggest that deferasirox may confer protection against iron-induced hepatic toxicity.

RESUMEN

Although the Foreign Pharmacy Graduate Equivalency Examination (FPGEE) is not intended to measure educational outcomes or institutional effectiveness, it may be a reliable and valid criterion to assess the quality or success of international pharmacy programs. This comprehensive review describes the evolution and historical milestones of the FPGEE, along with trends in structure, administration, and passing rates, and the impact of country of origin on participant performance. Similarities between the FPGEE and the Pharmacy Curriculum Outcomes Assessment (PCOA) are also explored. This paper aims to provide a global prospective and insight for foreign academic institutions into parameters for evaluating their students' educational capabilities.
