RESUMO

Objectives: Treatment options for preventing vaso-occlusive crises among sickle cell disease patients are on the rise, especially if hydroxyurea treatment has failed. This economic analysis is conducted to assess the comparative clinical effectiveness, safety, and acquisition cost of l-glutamine and crizanlizumab for older adolescents and adults (⩾16 years old) with sickle cell disease in Qatar, with an emphasis on treatment costs and acute pain crises. Methods: We conduct a decision-tree model, where we compare the clinical and economic outcomes of two novel Food and drug administration (FDA)-approved medications which are available in Qatar; l-glutamine and crizanlizumab over a time horizon of 1 year in a hypothetical cohort of adult sickle cell disease patients from a Qatar healthcare perspective. The main outcome is incremental cost per sickle cell disease-related acute pain crises averted. Model clinical parameters were derived from individual drug randomized trials, published literature, whereas cost parameters from Qatar healthcare payer system (2020-2021). A sensitivity analysis was carried out, and the study results were robust around model inputs. Costs were converted to 2020 US dollars. Results: Study results showed that both treatment modalities' costs were the main driver of this analysis, with an average annual cost of the treatments per patient being $189,014 for crizanlizumab (5 mg/kg), $143,798 for crizanlizumab (2.5 mg/kg), and $74,323 for l-glutamine. The probability of no first-time sickle cell disease-related vaso-occlusive crises averted was 0.001/year for glutamine, 0.26/year for crizanlizumab (5 mg/kg), and 0.34/year for crizanlizumab (2.5 mg/kg). Lower dose crizanlizumab (2.5 mg/kg) dominated the higher one (5 mg/kg). The incremental cost-effectiveness ratio of crizanlizumab (2.5 mg/kg), when compared to l-glutamine was $81,265 per sickle cell disease-related vaso-occlusive crises averted. When comparing crizanlizumab (5 mg/kg) and l-glutamine, crizanlizumab (5 mg/kg) showed higher efficacy, yet the crizanlizumab incremental cost-effectiveness ratio was at $459,620 than l-glutamine. Conclusions: Crizanlizumab (2.5 mg/kg) may be a cost-effective intervention, yet it is not the approved dose for preventing vaso-occlusive crises in adolescents and adults with sickle cell disease. Crizanlizumab (5 mg/kg) was more cost-effective than the approved l-glutamine per sickle cell disease vaso-occlusive crisis prevented. Of note, we primarily focused on modeling acute vaso-occlusive pain, which limited our ability to consider other key outcomes in sickle cell disease.

RESUMO

Academic Entitlement (AE) is the expectation by students to receive high grades or preferential treatment without significant effort. Exploring AE from faculty perspective has not been investigated in Arab colleges of pharmacy. The aim of this study was to explore experiences and perceptions towards student AE among pharmacy faculty in the Arab World. A cross-sectional, self-administered, anonymous, electronic survey was sent to pharmacy faculty across pharmacy colleges in Arab countries. The survey collected demographic data, an AE measure including 17 items reflecting seven AE components, and faculty perceptions and perceived reasons for AE. A total of 345 responses were collected. The AE level was moderate (46.05 ±7.29), and the highest scores among its components were for customer service expectation (62%) and responsibility avoidance (59%). In multiple linear regression, AE showed positive significant association with faculty in clinical pharmacy departments and those having fewer years of experience. Most common complaints heard by faculty from students were requests to turn in assignments late (90%), while the most common communication issues faculty faced with students were unprofessional verbal communication (58%) and unprofessional messages on social media (57%). Poor admission criteria (40%) and existence of multiple private colleges of pharmacy (37%) were the most common perceived reasons for AE by participating faculty. This study reveals moderate AE experienced by pharmacy faculty in the Arab World, as well as common complaints, communication issues, and AE reasons. In collaboration with other stakeholders, faculty play an important role in indicating expectations from students regarding AE, and research is warranted to check if such interventions reduce AE among pharmacy students.

RESUMO

PURPOSE: Selinexor is a first-in-class, oral selective-inhibitor-of-nuclear-export, granted accelerated approval by FDA (2019) for relapsed and refractory multiple myeloma (RRMM). We sought to quantitatively summarize the selinexor efficacy and safety in RRMM. METHODS: We searched PubMed, EMBASE, CENTRAL, clinicaltrial.gov, and google scholar, until May 2023, studies about selinexor use in RRMM. The outcome measures of interest were primarily efficacy outcomes, in addition to safety outcomes. Random-effect model analyses were performed, at statistical significance of P<0.05, using the RevMan software. RESULTS: Meta-analyses of eleven included clinical trials yielded a significant 56.21% overall clinical benefit, 46.91% overall response, 4.89% complete response, 23.41% very good partial response, 24.68% partial response, and 28.06% stable disease rates with selinexor. Due to safety reasons, selinexor caused significant increase in discontinuation rate, 16.80%. Subgroup analyses demonstrated higher efficacy with selinexor plus dexamethasone and proteasome inhibitor combinations than with selinexor alone. The multiple myeloma type, high cytogenetic risk, refractory state, and advanced disease state did not affect performance. Risk of selection, performance, and detection biases were unclear in the included trials. CONCLUSION: Selinexor led to significant positive responses with an acceptable safety profile in RRMM patients, despite higher rates of safety-related discontinuations. Selinexor-based combinations further enhanced response.

RESUMO

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.

RESUMO

INTRODUCTION: Drug-related problems (DRPs) affect the health outcomes of patients during hospitalization. We sought to analyze the clinical pharmacist-documented interventions among hospitalized patients in the cancer hospital in Qatar. METHODS: A retrospective analysis of electronically reported clinical pharmacist interventions of patients admitted to cancer units at Hamad Medical Corporation, Qatar was conducted. Extracted data was based on an overall 3-month follow-up period; March 1-31, 2018, July 15-August 15, 2018 and January 1-31, 2019. Categorical variables were expressed as frequencies and percentages, while continuous variables were expressed as mean ± standard deviation (SD). RESULTS: A total of 281 cancer patients with 1354 interventions were included. The average age of the study participants was 47 years (SD ± 17.36). The majority of the study population was females (n = 154, 54.80%). The prevailing pharmacist intervention was the addition of a drug therapy (n = 305, 22.53%), followed by medication discontinuation (n = 288, 21.27%) and the addition of a prophylactic agent (n = 174, 12.85%). This pattern was similar across all subgroups (i.e., gender, age, ward), except for the urgent care unit, where an increase in medication dose was the third highest frequently identified intervention (n = 3, 0.22%). The two medication groups associated with the majority of interventions were the anti-infective and fluid/electrolyte agents. Most of the interventions documented were in the oncology ward (73.19%), while the urgent care unit had the least documented interventions (1.62%). CONCLUSIONS: Our analysis showed that clinical pharmacists can effectively identify and prevent DRPs among hospitalized cancer patients.

RESUMO

The purpose of this study was to assess the efficacy of certain plant extracts and to compare them with current biocides on the viability of Acanthamoeba castellanii cysts and trophozoites in vitro. Amoebicidal and cysticidal assays were performed against both trophozoites and cysts of Acanthamoeba castellanii (ATCC 50370). Ten plant extracts were evaluated alongside the current agents included polyhexamethylene biguanide (PHMB), octenidine and chlorhexidine digluconate. A. castellanii (ATCC 50370) was treated to serial two-fold dilutions of the test compounds and extracts in microtitre plate wells to investigate the effect on trophozoites and cysts of A. castellanii (ATCC 50370). Furthermore, the toxicity of each of the test compounds and extracts were assessed towards a mammalian cell line. Minimum trophozoite inhibitory concentration (MTIC), minimum trophozoite amoebicidal concentration (MTAC), and minimum cysticidal concentration (MCC) were used to establish A. castellanii (ATCC 50370) in vitro sensitivity. The findings of this research revealed that the biguanides PHMB, chlorhexidine, and octenidine all had excellent effectiveness against trophozoites and cysts of A. castellanii (ATCC 50370). The plant extracts testing results showed that, great activity against trophozoites and cysts ofA. castellanii (ATCC 50370) at lower concentrations. This is the first study to demonstrate that the Proskia plant extract had the lowest MCC value, which was 3.9 µg/mL. The time kill experiment confirmed this finding, as this extract reduced cysts of A. castellanii (ATCC 50370) by more than 3-log at 6 hour and by 4-log after 24 hour. The anti-amoebic efficacy of new plant extracts on the viability of A. castellanii (ATCC 50370) cysts and trophozoites was comparable to existing biocide treatments and was not toxic when tested on a mammalian cell line. This could be a promising novel Acanthamoeba treatment by using the tested plant extracts as a monotherapy against trophozoites and cysts.

RESUMO

Objective: To investigate the post-COVID-19 long-term complications or long COVID of various organ systems in patients after 3 months of the infection, specifically before the Omicron variant, with comparative literature analysis. Methods: A systemic literature search and meta-analysis were conducted using multiple electronic databases (PubMed, Scopus, Cochrane library) with predefined search terms to identify eligible articles. Eligible studies reported long-term complications of COVID-19 infection before the Omicron variant infection. Case reports, case series, observational studies with cross-sectional or prospective research design, case-control studies, and experimental studies that reported post-COVID-19 complications were included. The complications reported after 3 months after the recovery from COVID-19 infection were included in the study. Results: The total number of studies available for analysis was 34. The effect size (ES) for neurological complications was 29% with 95% confidence interval (CI): 19%-39%. ES for psychiatric complications was 24% with 95% CI: 7%-41%. ES was 9% for cardiac outcomes, with a 95% CI of 1%-18%. ES was 22%, 95% CI: 5%-39% for the gastrointestinal outcome. ES for musculoskeletal symptoms was 18% with 95% CI: 9%-28%. ES for pulmonary complications was 28% with 95% CI: 18%-37%. ES for dermatological complications was 25%, with a 95% CI of 23%-26%. ES for endocrine outcomes was 8%, with a 95% CI of 8%-9%. ES size for renal outcomes was 3% with a 95% CI of 1%-7%. At the same time, other miscellaneous uncategorized outcomes had ES of 39% with 95% CI of 21%-57%. Apart from analyzing COVID-19 systemic complications outcomes, the ES for hospitalization and intensive care unit admissions were found to be 4%, 95% CI: 0%-7%, and 11% with 95% CI: 8%-14%. Conclusion: By acquiring the data and statistically analyzing the post-COVID-19 complications during the prevalence of most virulent strains, this study has generated a different way of understanding COVID-19 and its complications for better community health.

RESUMO

Purpose: This study was undertaken to investigate in-depth the factors impacting job satisfaction among pharmacists in the Arab world and the challenges they encounter in their career path. The outcome of this study should help the local policymakers to take corrective actions to improve pharmacist's satisfaction and therefore enhance quality of patient care. Method: This qualitative study collected responses of pharmacists from 12 Arab countries, as part of a large quantitative survey. Participants added comments to an optional open-ended question regarding work satisfaction. The Qualtrics Survey Software was used to collect the responses. The survey was distributed from March to May 2021 through multiple online channels for filling. The responses collected were analysed to develop themes. An inductive constructivist approach was used for the conceptual thematic analysis as the methodological orientation. Results: A total of 110 responses/comments were received from the study participants. The two largest practice settings of the participants were from hospitals (44.5%) and community pharmacies (28.2%). Almost 40% of responses came from pharmacists practising in Qatar (21.8%) and UAE (18.1%). The survey data demonstrated several reasons impacting job satisfaction among pharmacists practising in the Arab countries. Underestimation of the pharmacists' role, low salaries, lack of motivation and excessive workload were reported as major contributors to job dissatisfaction. On the other hand, professional commitment and the culture of the work setting were the major contributors to job satisfaction. Conclusions: The study provides valuable insights into the aspects concerning pharmacists' satisfaction in the Arab world. Policymakers and other stakeholders need to act upon aspects of pharmacists' job satisfaction and dissatisfaction to ensure potentially better working environment and patient outcomes.

RESUMO

BACKGROUND: The economic benefit of the clinical pharmacist's role in ensuring the optimum use of medicines is potentially considerable, particularly when it comes to cancer management. We sought to evaluate the overall economic impact of clinical pharmacist interventions in the main cancer setting in Qatar. METHODS: The total economic benefit of the clinical pharmacy interventions were analyzed from the public hospital perspective. Patient records in March 2018, July/August 2018, and January 2019 were retrospectively reviewed at the National Center for Cancer Care and Research, Qatar. The total benefit from interventions was the total cost avoidance due to preventable adverse drug events plus any cost savings associated with therapeutic-based resource use. Sensitivity analyses confirmed the results' robustness and increased generalizability. RESULTS: A total of 1352 interventions based on 281 patients were analyzed. The majority of the drug-related problems were related to the appropriateness of therapy, followed by dosing and administration. The total population benefit over the 3-months study period was QAR 4,879,185 (USD 1,336,763), constituting cost avoidance of QAR 4,234,012 (USD 1,160,003) and negative resource-use cost savings of -QAR 645,174 (-USD 176,760). Projected annual overall benefit was QAR 14,355,354 (USD 3,932,974). The increase in resource use with therapies was mostly because of the addition of other medications. Cost avoidance was mostly driven by recommending additional medications and discontinuation of medications. The uncertainty analysis demonstrated the robustness of outcomes. CONCLUSIONS: The clinical pharmacist intervention increased resource use and its cost. In overall, however, taking avoided cost of adverse drug events in consideration, it is an economically beneficial practice in the National Center for Cancer Care and Research setting, associated with adverse drug events prevention and substantial economic benefits.

RESUMO

BACKGROUND: In line with global trends, cancer incidence and mortality may have decreased for specific types of cancer in Qatar. However, the cancer-related burden on patients, healthcare systems, and the economy is expected to expand; thus, cancer remains a significant public healthcare issue in Qatar. Qatar's free access to cancer care represents a considerable economic burden. Ensuring the best utilization of financial resources in the healthcare sector is important to provide unified and fair access to cancer care for all patients. Experts from the Qatar Oncology Health Economics Expert Panel (Q-OHEP) aimed to establish a consistent and robust base for evaluating oncology/hematology medications; involve patients' insights to accelerate access to cutting-edge medications; increase the value of cancer care; and reach a consensus for using cost-effective strategies and efficient methodologies in cancer treatment. METHODS: The Q-OHEP convened on 30 November 2021 for a 3-hour meeting to discuss cancer management, therapeutics, and health economics in Qatar, focusing on four domains: (1) regulatory, (2) procurement, (3) treatment, and (4) patients. Discussions, guided by a moderator, focused on a list of suggested open-ended questions. RESULTS: Some of the salient recommendations included the development of a formal, fast-track, preliminary approval pathway for drugs needed by patients with severe disease or in critical condition; and encouraging and promoting the conduct of local clinical trials and real-world observational studies using existing registry data. The Q-OHEP also recommended implementing a forecast system using treatment center data based on the supply/demand of formulary oncology drugs to detect treatment patterns, estimate needs, expedite procurement, and prevent shortages/delays. Furthermore, the panel discussed the needs to define value concerning cancer treatment in Qatar, implement value-based models for reimbursement decision-making such as health technology assessment and multiple-criteria decision analysis, and promote patient education and involvement/feedback in developing and implementing cancer management guidelines. CONCLUSION: Herein, we summarize the first Q-OHEP consensus recommendations, which aim to provide a solid basis for evaluating, registering, and approving new cancer medications to accelerate patient access to novel cancer treatments in Qatar; promote/facilitate the adoption and collection of patient-reported outcomes; and implement value-based cancer care in Qatar.

RESUMO

BACKGROUND: There is a paucity of studies about the readiness of community pharmacists to manage the safe and effective use of oral anticancer medicines (OAMs) in developing settings. OBJECTIVES: Using the readiness component (knowledge and willingness) of the situational theory of leadership, the study assessed community pharmacists' readiness to manage the safe and effective use of OAMs in Qatar, and also identified its significant predictors. METHODS: A cross-sectional assessment of 252 community pharmacists was conducted with a pre-tested 48-item questionnaire. Readiness was assessed with a 5-point Likert-type scale and the maximum obtainable score was 70. The mean was used as the cut-off point to categorize willingness and knowledge as either high (≥ mean) or low (< mean). Independent t-test, one-way analysis of variance and multiple linear regression was used for data analyses. RESULTS: The mean SD score for the readiness of community pharmacists was 39.3 ± 11.2 (min = 11, max = 70). Only a minority of the respondents expressed an excellent understanding of the chemotherapy cycles (19.6%; 45/230), and familiarity with targeted anticancer therapy (14.3%; 33/230), side effects (22.2%; 51/230), and dosing of OAMs (14.4%; 33/230). Employment status, number of OAMs prescriptions dispensed per month and adequacy of the contents related to OAMs in undergraduate training were the significant predictors of readiness (R2 = 0.558, (F (11, 209) = 3.559, p = 0.0001). CONCLUSIONS: Community pharmacists' readiness appear inadequate especially regarding its dosing, side effects, handling, and disposal of OAMs. These inadequacies probably underline community pharmacists' low familiarity and comfortability with dispensing and educating patients on the effective and safe use of OAMs.

RESUMO

Introduction: There is an increased interest in cost consciousness concerning healthcare spending worldwide. In the Arab world, a major transformation is underway in the healthcare sectors to achieve national and government visions to attain better outcomes with optimal value. This article contains expert recommendations on how decision-makers can implement pharmacoeconomic principles at a national level in the Arab world. Methods: A multidisciplinary panel of experts was formed of policymakers, clinical pharmacists, health economists, and chronic disease control and public health experts from different countries and healthcare sectors. The panel developed consensus recommendations for different stakeholders using a framework analysis method. Results: The experts discussed the limitations and opportunities of implementing the pharmacoeconomics concept in evaluating new technologies in their respective countries. Common limitations recognized in the included countries were a lack of infrastructure to support the adoption of the concept in practice, challenges in obtaining data to support the decision-making process, and the lack of human resources to raise awareness among decision-makers and the public to use health economics in making informed decisions in reimbursing new technologies. Conclusion: The expert panel recommendations will guide relevant stakeholders at a national level per country. Adapting these recommendations to each setting is essential to accommodate the situation and needs of each country.

RESUMO

Introduction: Palbociclib and ribociclib are indicated in the first-line treatment of hormonal receptor-positive HER-2 negative (HR+/HER2- negative) advanced breast cancer. Although randomized-controlled trials (RCTs) proved their clinical efficacy, there are no observational studies yet to validate the clinical findings in the real-world. Therefore, this study aimed to evaluate and compare the clinical effectiveness and safety profiles of palbociclib and ribociclib in Qatar. Materials and methods: A retrospective observational study was conducted on HR+/HER-2-negative stage-IV breast cancer patients receiving palbociclib or ribociclib in the state of Qatar. Clinical data were collected from the National Center for Cancer Care and Research (NCCCR) in Qatar using Cerner®. Primary outcomes were progression-free-survival (PFS) and overall-survival (OS) generated by Kaplan-Meier curves. Moreover, safety profiles of both two treatments were evaluated. Results: The data from 108 patients were included in the final analysis. There was no statistically significant difference in PFS between the palbociclib and ribociclib groups; PFS was 17.85 versus 13.55 months, respectively(p> 0.05). Similarly, there was no statistically significant difference in OS between the two medications, 29.82 versus 31.72 months, respectively(p>0.05). Adverse events were similar between the two groups. Neutropenia was the most common side effect in the study population accounting for 59.3% of the patients. Conclusions: Therefore, both treatments have similar efficacy and safety profiles. Further research on a larger-scale population and longer follow-up period is recommeneded.

RESUMO

Introduction: Immune checkpoint blockade (ICB)-based therapy is revolutionizing cancer treatment by fostering successful immune surveillance and effector cell responses against various types of cancers. However, patients with HER2+ cancers are yet to benefit from this therapeutic strategy. Precisely, several questions regarding the right combination of drugs, drug modality, and effective dose recommendations pertaining to the use of ICB-based therapy for HER2+ patients remain unanswered. Methods: In this study, we use a mathematical modeling-based approach to quantify the growth inhibition of HER2+ breast cancer (BC) cell colonies (ZR75) when treated with anti-HER2; trastuzumab (TZ) and anti-PD-1/PD-L1 (BMS-202) agents. Results and discussion: Our data show that a combination therapy of TZ and BMS-202 can significantly reduce the viability of ZR75 cells and trigger several morphological changes. The combination decreased the cell's invasiveness along with altering several key pathways, such as Akt/mTor and ErbB2 compared to monotherapy. In addition, BMS-202 causes dose-dependent growth inhibition of HER2+ BC cell colonies alone, while this effect is significantly improved when used in combination with TZ. Based on the in-vitro monoculture experiments conducted, we argue that BMS-202 can cause tumor growth suppression not only by mediating immune response but also by interfering with the growth signaling pathways of HER2+BC. Nevertheless, further studies are imperative to substantiate this argument and to uncover the potential crosstalk between PD-1/PD-L1 inhibitors and HER2 growth signaling pathways in breast cancer.

RESUMO

Outpatient Chemotherapy Appointment (OCA) planning and scheduling is a process of distributing appointments to available days and times to be handled by various resources through a multi-stage process. Proper OCAs planning and scheduling results in minimizing the length of stay of patients and staff overtime. The integrated consideration of the available capacity, resources planning, scheduling policy, drug preparation requirements, and resources-to-patients assignment can improve the Outpatient Chemotherapy Process's (OCP's) overall performance due to interdependencies. However, developing a comprehensive and stochastic decision support system in the OCP environment is complex. Thus, the multi-stages of OCP, stochastic durations, probability of uncertain events occurrence, patterns of patient arrivals, acuity levels of nurses, demand variety, and complex patient pathways are rarely addressed together. Therefore, this paper proposes a clustering and stochastic optimization methodology to handle the various challenges of OCA planning and scheduling. A Stochastic Discrete Simulation-Based Multi-Objective Optimization (SDSMO) model is developed and linked to clustering algorithms using an iterative sequential approach. The experimental results indicate the positive effect of clustering similar appointments on the performance measures and the computational time. The developed cluster-based stochastic optimization approaches showed superior performance compared with baseline and sequencing heuristics using data from a real Outpatient Chemotherapy Center (OCC).

RESUMO

Ventilator-associated pneumonia (VAP) is a prevalent nosocomial illness in mechanically ventilated patients. Hence, the aim of this study was to investigate the pattern of antibiotic resistance and biofilm formation of bacterial profiles from Endotracheal Tubes of patients hospitalized in an intensive care unit in southwest Iran. According to the standard operating method, the microbiological laboratory conducts bacteria culture and susceptibility testing on endotracheal Tube samples suspected of carrying a bacterial infection. The Clinical and laboratory standards institute (CLSI) techniques are used to determine the Antimicrobial resistance (AMR) of bacterial isolates to antibiotics using the disk diffusion method. The crystal violet staining method was used to assess the biofilm-forming potential of isolates in a 96-well microtiter plate. In total, (51%) GPBs were included in this study. The isolated GPB were coagulase-negative Staphylococcus (16%), S. aureus (14%). In total, (40%) of GNB were included in this study. The isolated GNB were Klebsiella spp. (36%), A. baumannii (22%), P. aeruginosa (35%). (32%) bacterial strains were MDR and (29%) strains were XDR. The results of biofilm formation showed (72%) were biofilm producers. VAP is a common and severe nosocomial infection in mechanically ventilated patients. Controlling biofilm formation, whether on the ET or in the oropharyngeal cavity, is thus an important technique for treating VAP. Colistin and linezolid are antibiotics that are effective against practically all resistant GNB and GPB isolates.

RESUMO

Home cancer care research (HCCR) has accelerated, as considerable attention has been placed on reducing cancer-related health costs and enhancing cancer patients' quality of life. Understanding the current status of HCCR can help guide future research and support informed decision-making about new home cancer care (HCC) programs. However, most current studies mainly detail the research status of certain components, while failing to explore the knowledge domain of this research field as a whole, thereby limiting the overall understanding of home cancer care. We carried out bibliometric and visualization analyses of Scopus-indexed papers related to home cancer care published between 1990-2021, and used VOSviewer scientometric software to investigate the status and provide a structural overview of the knowledge domain of HCCR (social, intellectual, and conceptual structures). Our findings demonstrate that over the last three decades, the research on home cancer care has been increasing, with a constantly expanding stream of new papers built on a solid knowledge base and applied to a wide range of research themes.

RESUMO

Surface-growing antibiotic-resistant pathogenic bacteria such as Escherichia coli and Staphylococcus aureus are emerging as a global health challenge due to dilemmas in clinical treatment. Furthermore, their pathogenesis, including increasingly serious antimicrobial resistance and biofilm formation, makes them challenging to treat by conventional therapy. Therefore, the development of novel antivirulence strategies will undoubtedly provide a path forward in combatting these resistant bacterial infections. In this regard, we developed novel biosurfactant-coated nanoparticles to combine the antiadhesive/antibiofilm properties of rhamnolipid (RHL)-coated Fe3O4 nanoparticles (NPs) with each of the p-coumaric acid (p-CoA) and gallic acid (GA) antimicrobial drugs by using the most available polymer common coatings (PVA) to expand the range of effective antibacterial drugs, as well as a mechanism for their synergistic effect via a simple method of preparation. Mechanistically, the average size of bare Fe3O4 NPs was ~15 nm, while RHL-coated Fe3O4@PVA@p-CoA/GA was about ~254 nm, with a drop in zeta potential from -18.7 mV to -34.3 mV, which helped increase stability. Our data show that RHL-Fe3O4@PVA@p-CoA/GA biosurfactant NPs can remarkably interfere with bacterial growth and significantly inhibited biofilm formation to more than 50% via downregulating IcaABCD and CsgBAC operons, which are responsible for slime layer formation and curli fimbriae production in S. aureus and E. coli, respectively. The novelty regarding the activity of RHL-Fe3O4@PVA@p-CoA/GA biosurfactant NPs reveals their potential effect as an alternative multitarget antivirulence candidate to minimize infection severity by inhibiting biofilm development. Therefore, they could be used in antibacterial coatings and wound dressings in the future. IMPORTANCE Antimicrobial resistance poses a great threat and challenge to humanity. Therefore, the search for alternative ways to target and eliminate microbes from plant, animal, and marine microorganisms is one of the world's concerns today. Furthermore, the extraordinary capacity of S. aureus and E. coli to resist standard antibacterial drugs is the dilemma of all currently used remedies. Methicillin-resistant S. aureus (MRSA) and vancomycin-resistant S. aureus (VRSA) have become widespread, leading to no remedies being able to treat these threatening pathogens. The most widely recognized serotypes that cause severe foodborne illness are E. coli O157:H7, O26:H11, and O78:H10, and they display increasing antimicrobial resistance rates. Therefore, there is an urgent need for an effective therapy that has dual action to inhibit biofilm formation and decrease bacterial growth. In this study, the synthesized RHL-Fe3O4@PVA@p-CoA/GA biosurfactant NPs have interesting properties, making them excellent candidates for targeted drug delivery by inhibiting bacterial growth and downregulating biofilm-associated IcaABCD and CsgBAC gene loci.

RESUMO

BACKGROUND: Eltrombopag olamine (ELT) is a synthetic nonpeptide with a low molecular weight that has been investigated in various phase-3 studies and shown to be efficacious at a typical dose of 50 mg. Varied ethnic groups have reported different responses to ELT. AIM: The aim is to examine the efficacy of ELT in Asian and Arab patients with immune thrombocytopenia (ITP) from the Indian subcontinent by starting with (12.5 mg, as a minimum dose) and gradually increasing to a maximum dose of 50 mg. METHODS: Between January 2015 and January 2019, we reviewed the electronic health records of non-Arab Asian (n = 17) versus Arab (n = 41) patients who were ≥18 years old, residing in Qatar, and with confirmed diagnoses with chronic ITP and under active treatment with a platelet count of 30,000/L, and bleeding symptoms. Following receiving ELT for three months or longer at various dosages, patients' response was examined. RESULTS: After three months of ELT therapy, the response rate (platelet count of 50,000/L) was equivalent in non-Arab (88.2%) versus Arab (87.5%) patients. However, to achieve an adequate response, 26% of Arab patients required a lower dose of 12.5 or 25 mg, and 41.5% required a higher dose of 50 mg. CONCLUSION:  In adult chronic ITP patients, ELT is typically well-tolerated and delivers the desired outcomes. In 67.5% of Arab patients, smaller dosages of ELT (12.5-50 mg) were helpful in sustaining acceptable PLT levels. This helps patients get the most benefit at the lowest feasible dose, reducing toxicity and expense.

RESUMO

OBJECTIVES: The study objectives were to (1) describe the characteristics of the pharmacy professionals and (2) explore the association between job satisfaction and factors, such as work control, work stress, workload and organization and professional commitments. METHODS: This study was a cross-sectional design. The survey items were mainly adapted from the US National Pharmacist Workforce Survey. An electronic (Qualtrics) questionnaire was posted on pharmacist social media in several Arab countries. The survey link was posted from 22 March 2021 to 1 May 2021. The multiple linear regression measured the association between 12 independent variables and pharmacist job satisfaction. KEY FINDINGS: A total of 2137 usable surveys were received from pharmacists (54.7% female) working in 18 Arabic countries. The job satisfaction rate varied among countries in the Arab world. The fields with the highest satisfaction average included pharmaceutical marketing, academia and the pharmaceutical industry. At the same time, pharmacists working in community pharmacy and Ministry of Health/administrative positions had the lowest satisfaction rates. Overall, pharmacist satisfaction was average (3.1 out of 5). The pharmacists had the lowest satisfaction averages with income and job expectations. The pharmacists with bachelor's degrees had significantly lower satisfaction than pharmacists with postgraduate degrees. Male pharmacists had significantly higher job satisfaction compared with female pharmacists. Workload and the feelings of organization and professional commitments had significant positive associations with job satisfaction. CONCLUSIONS: The pharmacy profession in Arabic countries faced several challenges that negatively impacted job satisfaction. Improving work environment, professional management, income and organization loyalty is necessary to enhance pharmacist job satisfaction.
