Prevalence and risk factors of osteopenia and osteoporosis among postmenopausal women: A cross-sectional study from Jordan.

OBJECTIVES: Our aim was to predict the prevalence of osteopenia and osteoporosis and their associated risk factors among postmenopausal women from Jordan. METHODOLOGY: In this cross-sectional study, a total of 368 postmenopausal women were recruited from King Abdullah University Hospital (KAUH) in the North of Jordan between September 2022 and April 2023. Bone mineral density (BMD) was measured using a dual-energy X-ray absorptiometry scan. T-score was used for osteoporosis diagnosis in accordance with the International Society for Clinical Densitometry (ISCD) guidelines. Data about sociodemographic and lifestyle variables were collected using face-to-face interviews. Medical records were used to retrieve participants' BMD information. Predictors of osteoporosis were identified using logistic regression. RESULTS: Prevalence of osteoporosis was 40.5%, while 44.6% of participants were diagnosed with osteopenia. The lumbar spine had the highest frequency of osteoporosis (30.4%), while the left femoral neck had the highest prevalence of osteopenia (46.3%). Postmenopausal women's age (p-value = .024), and history of chronic diseases (p-value = .038) were significant factors associated with increased osteoporosis risk. CONCLUSIONS: Postmenopausal women from Jordan had high prevalence of osteoporosis and osteopenia. It is therefore necessary to target risk factors leading to osteoporosis and to improve patients' lifestyles through patient education. Healthcare systems should consider early screening approaches for osteoporosis at the age of menopause and thereafter. Supplements of calcium and vitamin D may be routinely considered for this age group depending on their serum levels.

Drugs in Human Milk Part 1: Practical and Analytical Considerations in Measuring Drugs and Metabolites in Human Milk.

Human milk is a remarkable biofluid that provides essential nutrients and immune protection to newborns. Breastfeeding women consuming medications could pass the drug through their milk to neonates. Drugs can be transferred to human milk by passive diffusion or active transport. The physicochemical properties of the drug largely impact the extent of drug transfer into human milk. A comprehensive understanding of the physiology of human milk formation, composition of milk, mechanisms of drug transfer, and factors influencing drug transfer into human milk is critical for appropriate selection and use of medications in lactating women. Quantification of drugs in the milk is essential for assessing the safety of pharmacotherapy during lactation. This can be achieved by developing specific, sensitive, and reproducible analytical methods using techniques such as liquid chromatography coupled with mass spectrometry. The present review briefly discusses the physiology of human milk formation, composition of human milk, mechanisms of drug transfer into human milk, and factors influencing transfer of drugs from blood to milk. We further expand upon and critically evaluate the existing analytical approaches/assays used for the quantification of drugs in human milk.

Knowledge and attitude of healthcare prescribers and pharmacists toward antimicrobial stewardship program and the barriers for its implementation.

BACKGROUND: Antimicrobial stewardship (ASP) is considered a key prevention strategy in addressing the worldwide concern of accelerating antimicrobial resistance. Limited research is available regarding healthcare providers' knowledge and attitude toward antimicrobial stewardship and the barriers for its implementation. METHODS: The present cross-sectional study was conducted on pharmacists and healthcare prescribers (HCPs) in different hospital sites across Jordan. A validated survey was used to evaluate HCPs and pharmacists' knowledge, and attitudes towards ASP and the barriers for its implementation. Logistic and linear regression were conducted to identify the factors associated with knowledge and attitude toward ASP, respectively. RESULTS: A total of 603 participants, 69 (11.4%) pharmacists and 534 (88.6%) HCPs completed the study questionnaire, with a response rate of 80.4%. The overall mean knowledge about ASP was 7.16 out of 10, ranging from 0 to 10 (SD 2.22). Being a pharmacist and increased awareness/familiarity about ASP were associated with improved ASP knowledge. The overall average attitude score was = 3.8 ± 0.49 (range: 1.8-4.8). Results revealed that being a pharmacist and improved knowledge were associated with improved attitude toward ASP. Lack of specialized staff with expertise in ASP and lack of access to education and training programs were the major barriers hinder ASP implementation. CONCLUSION: Despite the reasonable knowledge and the positive attitude toward the ASP, several barriers were reported, particularly by the pharmacists. Therefore, promoting the presence of adequately skilled healthcare personnel, creating easily accessible online courses, and establishing a comprehensive database of ASP resources are all suggested approaches to improve the application of ASP in healthcare settings.

Simplified processing and rapid quantification of buprenorphine, norbuprenorphine, and their conjugated metabolites in human plasma using UPLC-MS/MS: Assessment of buprenorphine exposure during opioid use disorder treatment.

Opioid use disorder (OUD) is a chronic neurobehavioral ailment and is prevalent in pregnancy. OUD is commonly treated with methadone or buprenorphine (BUP). Pregnancy is known to alter the pharmacokinetics of drugs and may lead to changes in drug exposure and response. A simple, specific, and sensitive analytical method for measuring the parent drug and its metabolites is valuable for assessing the impact of pregnancy on drug exposure. A new liquid chromatography-tandem mass spectrometric method that utilized a simple protein precipitation procedure for sample preparation and four deuterated internal standards for quantification was developed and validated for BUP and its major metabolites (norbuprenorphine [NBUP], buprenorphine-glucuronide [BUP-G], and norbuprenorphine-glucuronide [NBUP-G]) in human plasma. The standard curve was linear over the concentration range of 0.05-100 ng/mL for BUP and NBUP, and 0.1-200 ng/mL for BUP-G and NBUP-G. Intra- and inter-day bias and precision were within ±15% of nominal values for all the analytes. Quality controls assessed at four levels showed high recovery consistently for all the analytes with minimal matrix effect. Adequate analyte stability was observed at various laboratory conditions tested. Overall, the developed method is simple, sensitive, accurate and reproducible, and was successfully applied for the quantification of BUP and its metabolites in plasma samples collected from pregnant women in a clinical study assessing BUP exposure during OUD treatment.

Simple and rapid quantification of ribociclib in rat plasma by protein precipitation and LC-MS/MS: An application to pharmacokinetics of ribociclib nanoparticles in rats.

Ribociclib is a cyclin-dependent kinase (CDK4/6) inhibitor and is a standard of care for treating metastatic breast cancer. The drug has moderate oral bioavailability and exhibits permeability-controlled absorption. Novel formulations to enhance ribociclib pharmacokinetics are being developed and tested in rats. This requires developing analytical assays for quantifying ribociclib monitoring in rat plasma. We present a fully validated, sensitive, and simple LC-MS/MS method for measuring ribociclib in rat plasma. Ribociclib-D6 was utilized as an internal standard, and a simple protein precipitation procedure with acetonitrile was used in sample preparation. Excellent assay linearity was observed over a standard curve concentration of 1.008-1027.624 ng/mL. Acceptable intra- and inter-day accuracy and reproductivity were demonstrated for ribociclib quality controls (bias and CV% within ±15%). Complete extraction recovery of ribociclib was achieved, and a negligible matrix effect of analyte to internal standard ratio was observed. Ribociclib was stable at various conditions, including bench-top, freeze-thaw, and short-term stability. Overall, the presented method is simple, sensitive, accurate, and precise and was successfully applied to quantify ribociclib in plasma samples from a pharmacokinetic study of ribociclib suspension and nanoparticle formulation in rats.

Self-reported urinary urgency in association with vitamin D and psychiatric symptoms among patients with musculoskeletal pain.

OBJECTIVES: Urinary urgency (UU) is linked to musculoskeletal pain (MSP), and it is associated with mental health conditions. This study examined the prevalence of UU morbidity among outpatients with MSP, and the possible association of UU with psychological symptoms and vitamin D deficiency. MATERIALS AND METHODS: A cross-sectional study was conducted among 169 participants recruited from outpatient clinics at King Abdullah University Hospital in Jordan. Participants completed self-guided questionnaires that included information about MSP and UU. Psychological symptoms were evaluated using the Hospital Anxiety and Depression Scale (HADS). A blood sample was collected for measuring vitamin D levels. Regression analysis was performed to explore predictors of MSP and UU. RESULTS: Vitamin D deficiency was presented in 64.5% of participants, while UU was reported among 35.4% of MSP patients. Approximately 1/3 of participants had psychiatric symptoms (HADS ≥ 8). Regression analyses revealed a significant association between vitamin D deficiency, low calcium intake, and anxiety scores with MSP (p < 0.05), while anxiety score was a significant predictor of UU among MSP patients (adjusted OR = 4.26, p = 0.038). A moderately significant correlation between anxiety score and frequency of UU per day was also observed (r = 0.303, p = 0.041). CONCLUSION: Urinary urgency was prevalent among MSP patients and was strongly associated with anxiety symptoms. The findings suggest the importance of assessment of MSP patients for UU and the associated psychological symptoms so interventions may be potentially implemented to improve patients' health conditions.

Assessment of osteoporosis knowledge, awareness, and risk factors among premenopausal and postmenopausal women from Jordan: a cross-sectional study.

RATIONALE: Lack of information about osteoporosis knowledge and awareness among premenopausal compared to postmenopausal women in Jordan. MAIN RESULT: Women had an average-poor knowledge and awareness about osteoporosis. SIGNIFICANCE: This study highlights the need to improve women's knowledge about osteoporosis, its consequences, potential risk factors, preventive measures, and treatment options. PURPOSE: To assess osteoporosis knowledge, awareness, and risk factor profile among premenopausal and postmenopausal women from Jordan. METHODS: This was a cross-sectional study that involved 490 premenopausal and 488 postmenopausal women from the general population of Jordan. Face-to-face interviews were conducted to collect the sociodemographic and clinical data and to complete the Osteoporosis Knowledge Assessment Tool (OKAT) questionnaire. RESULTS: Premenopausal and postmenopausal women had an average-poor level of knowledge and awareness regarding osteoporosis, with a total mean score of 51.3 and 50.9, respectively, out of the total OKAT score of 100. More than 50% of premenopausal women correctly answered 11 questions, while >50% of postmenopausal women correctly answered 9 questions out of 20 in OKAT, which are related to knowledge and awareness about osteoporosis. The participants' marital status (being married), higher educational level, and higher economic status were significantly associated with better knowledge and awareness about osteoporosis (p-values < 0.05). Postmenopausal women had higher osteoporosis risk profile including older age, higher body mass index, less regular exercise, and less exposure to sunlight versus premenopausal women. CONCLUSION: Premenopausal and postmenopausal women from Jordan had an average-poor level of knowledge and awareness about osteoporosis. Higher educational levels and higher income are associated with better knowledge and awareness about osteoporosis. It is therefore crucial to improve the knowledge of women in Jordan about osteoporosis and its consequences, as well as the potential risk factors, preventive measures, and treatment options. Conducting periodic osteoporosis awareness and educational campaigns are necessary to spread the awareness of the disease.

Ribociclib Hybrid Lipid-Polymer Nanoparticle Preparation and Characterization for Cancer Treatment.

Ribociclib is a newly approved orally administered drug for breast cancer. This study aimed to prepare, characterize, and evaluate hybrid lipid-polymer nanoparticles (PLNs) of ribociclib to enhance its in vitro dissolution rate, pharmacokinetics, and anticancer efficacy. Ribociclib-loaded PLNs were prepared by solvent evaporation using the Box-Behnken design to optimize formulation variables. Particle size, entrapment efficiency, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), atomic force microscopy (AFM), in vitro release cytotoxicity, molecular modeling, and pharmacokinetic studies were examined. The ribociclib-loaded PLN (formula 1, F1) was optimized in terms of particle size (266.9 ± 4.61 nm) and encapsulation efficiency (59.1 ± 2.57 mg/mL). DSC and thermogravimetric characterization showed the absence of a crystalline structure in the prepared PLNs, confirmed by FTIR, and showed no interactions between the components and the drug. AFM showed well-dispersed heterogeneously shaped nanoparticles. The in vitro release profile exhibited significant results for the optimized formula, reaching 100% at 600 and 90 min at pH 6.8 and 1.2, respectively. The low IC50 obtained by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay suggests that optimized PLN might serve as an effective delivery vehicle for cancer treatment, especially breast and lung cancer. Molecular modeling revealed several hydrogen bonds. A pharmacokinetic study in rats showed that the ribociclib formula had a 6.5-fold increase in maximum concentration (Cmax) and a 5.6-fold increase in area under the curve (AUC). Regarding the everted intestinal sac absorption, formula 1 increased ribociclib penetration relative to the physical combination and pure medication. In conclusion, optimized PLNs with enhanced physicochemical and cytotoxic properties and improved pharmacokinetic parameters were successfully prepared.

Simultaneous quantitation of ketamine, norketamine and dehydronorketamine in human milk using a novel ultra high-performance liquid chromatography-mass spectrometry (UPLC-MS/MS) assay.

There is a paucity of data on the transfer of ketamine from maternal blood into human milk. Quantification of ketamine in human milk provides information about the potential exposure of the infant to ketamine and its metabolites from the mother during lactation. A highly specific, reproducible, and sensitive UPLC-MS/MS based analytical method was developed and validated for the quantitation of ketamine and its metabolites (norketamine and dehydronorketamine) in human milk. Samples were subjected to a simple protein precipitation and ketamine-d4 and norketamine-d4 were used as internal standards. Separation of the analytes was achieved using an Acquity UPLC equipped with BEH RP18 1.7 µm, 2.1 × 100 mm column. Mass spectrometric analysis of the analyte ions was carried out using electrospray with positive ionization and multiple reaction monitoring mode. The assay was linear over a concentration range of 1-100 ng/mL for ketamine and norketamine, and 0.1-10 ng/mL for dehydronorketamine. Acceptable intra-day and inter-day accuracy and precision were observed for all the analytes. High recovery of the analytes and minimal matrix effect were observed. Stability of analytes was confirmed at the tested conditions. This assay was successfully used to measure analytes in human milk samples collected from lactating women enrolled in a clinical research study. This is the first validated method that simultaneously quantified ketamine and its metabolites in human milk.

Patterns of adverse drug reactions in Jordan: a retrospective analysis of the National Pharmacovigilance Data Registry (2015-2021).

BACKGROUND: Post-marketing surveillance of drugs is a cornerstone of pharmacovigilance. This study was conducted to characterize patterns of adverse drug reactions (ADRs) reported in Jordan. RESEARCH DESIGN AND METHODS: ADR reports submitted to the pharmacovigilance database of the Jordan Food and Drug Administration during 2015-2021 were retrospectively analyzed. The most commonly reported drugs, drug classes, ADRs, and ADRs consequences were explored. Logistic regression identified possible predictors of reporting serious ADRs. RESULTS: A total of 2744 ADR reports were included, among which 28.4% were classified as serious. An annual increase in ADR reporting was observed. The most commonly implicated drug classes were antineoplastic and immunomodulating agents (24.0%), anti-infectives for systemic use (14.2%), and alimentary tract and metabolism (12.1%). Covid-19 vaccination was the most reported drug (22.8%). Fatigue (6.3%), injection site pain (6.1%), and headache (6.0%) were the top three common ADRs. Among ADRs with outcome information, 4.7% were fatal. Patient's age and intravenous medication use largely predicted reporting serious ADRs. CONCLUSIONS: This study provides contemporary insights into the post-marketing surveillance of drugs in Jordan. The findings are foundational for future studies exploring drug-ADRs causality relationships. Efforts that promote pharmacovigilance concepts should be sustained and enhanced at the national level.

Reporting Antimicrobial-Related Adverse Drug Events in Jordan: An Analysis from the VigiBase Database.

This study aims to assess the reporting of antimicrobial-related adverse drug events (ADEs) in Jordan between 2003 and 2022. Data regarding the antimicrobial-related ADEs were extracted from the WHO's global database (VigiBase) by the Rational Drug Use and Pharmacovigilance Department at the Jordan Food and Drug Administration (JFDA). A total of 279 Individual Case Safety Reports (ICSRs) were recorded. The number of ICSRs increased from 2019 onwards (219 out of 279 cases). This increase in the reported ADEs was influenced by the actions of the JFDA, including the introduction of electronic reporting forms, updating the national pharmacovigilance guidelines, which encouraged adverse drug reactions reporting, the implementation of the AMR-national action plan, the encouragement to report due to COVID-19 vaccine, and the continuous awareness campaigns and training programs. Skin and subcutaneous tissue disorders (n = 105; 19.48%) were the most reported antimicrobial-related ADEs. The highest number of ADEs was reported for tetracyclines (n = 101; 18.74%) followed by fluoroquinolones (n = 54; 10.02%), third-generation cephalosporines (n = 48; 8.9%), and carbapenems (n = 42; 7.79%). From the top 10 consumed antibiotics, the number of ADEs in patients who consumed Watch group antibiotics (97 ADEs) was higher than those who consumed Access group antibiotics (28 ADEs). The findings highlight the need to monitor and rationalize the use of Watch antibiotics. Enhanced reporting of antimicrobial-related adverse drug reactions is needed to inform antimicrobial stewardship and improve the pharmacovigilance system in Jordan.

Healthcare Professionals' Perceptions, Barriers, and Facilitators towards Adopting Computerised Clinical Decision Support Systems in Antimicrobial Stewardship in Jordanian Hospitals.

Understanding healthcare professionals' perceptions towards a computerised decision support system (CDSS) may provide a platform for the determinants of the successful adoption and implementation of CDSS. This cross-sectional study examined healthcare professionals' perceptions, barriers, and facilitators to adopting a CDSS for antibiotic prescribing in Jordanian hospitals. This study was conducted among healthcare professionals in Jordan's two tertiary and teaching hospitals over four weeks (June-July 2021). Data were collected in a paper-based format from senior and junior prescribers and non-prescribers (n = 254) who agreed to complete a questionnaire. The majority (n = 184, 72.4%) were aware that electronic prescribing and electronic health record systems could be used specifically to facilitate antibiotic use and prescribing. The essential facilitator made CDSS available in a portable format (n = 224, 88.2%). While insufficient training to use CDSS was the most significant barrier (n = 175, 68.9%). The female providers showed significantly lower awareness (p = 0.006), and the nurses showed significantly higher awareness (p = 0.041) about using electronic prescribing and electronic health record systems. This study examined healthcare professionals' perceptions of adopting CDSS in antimicrobial stewardship (AMS) and shed light on the perceived barriers and facilitators to adopting CDSS in AMS, reducing antibiotic resistance, and improving patient safety. Furthermore, results would provide a framework for other hospital settings concerned with implementing CDSS in AMS and inform policy decision-makers to react by implementing the CDSS system in Jordan and globally. Future studies should concentrate on establishing policies and guidelines and a framework to examine the adoption of the CDSS for AMS.

Incidence, predictors, clinical outcomes, and economic burden of recurrent acute kidney injury: a retrospective cohort study.

OBJECTIVE: This study aimed to assess the incidence, predictors, mortality, and economic outcomes of recurrent Acute kidney injury (AKI) in Jordan. METHODS: This was a retrospective cohort study that included adult patients who were admitted with AKI to university hospitals in the country from 2010-2019. Recurrent episodes of AKI, laboratory data, baseline medication list, and death dates were retrieved from patient's medical records. The incidence rate of recurrent AKI was estimated. Predictors of recurrent AKI and mortality during the five years post-discharge was evaluated. Total admission charges were described and evaluated in total and by service provided. RESULTS: Among 1162 AKI patients, 57 patients (4.9%) died during the index admission (first admission during the study period), and among the survivors, 220 patients were re-hospitalized with a recurrent AKI during five years of follow-up. Patients with higher discharge serum creatinine level (SCr) at index admission had higher odds of AKI recurrence (OR = 1.001). Patients who were on respiratory, antineoplastic, or anticoagulant medications were also more susceptible to recurrence; ORs were 1.69, 2.77, and 4.16, respectively. Patients who were elderly, with recurrent AKI episodes, or with a more extended hospital stay at index admission were more likely to die during the five years post discharge. The median charge of recurrent admissions was higher than the median charge of the index admissions; 1519.17 JOD ($2142.7) versus 1362.85 JOD ($1922.2), respectively. CONCLUSIONS: Recurrent AKI is associated with increased mortality and health expenditures. Higher discharge SCr levels at index admission, and chronic comorbidities are associated with a higher likelihood of AKI recurrence.

Acute kidney injury development and impact on clinical and economic outcomes in patients with cirrhosis: an observational cohort study over a 10-year period.

OBJECTIVES: Acute kidney injury (AKI) is a severe complication that is associated with significant morbidity and mortality in hospitalized cirrhotic patients. Data about AKI incidence and outcomes in patients with cirrhosis is scarce in the Middle East region. This study explored the incidence and impact of AKI on clinical and economic outcomes in cirrhosis. METHODS: This was a retrospective cohort study of cirrhosis patients admitted to an educational hospital in Jordan during the years 2012-2022. Demographics, clinical and biochemical information, and charges were retrieved from medical electronic records. Logistic regression models were conducted to evaluate predictors of AKI and mortality in cirrhosis adjusting for covariates. Hospital charges were also described. RESULTS: A total of 380 cirrhosis patients were included with an AKI incidence of 27.9%. Male sex, elevated baseline serum creatinine, presence of spontaneous bacterial peritonitis, and higher comorbidity score were independently associated with AKI development ( P < 0.05). The hospital mortality rate was markedly higher for patients with AKI versus those without AKI (51.9% vs. 6.2%, respectively; P < 0.001). AKI was associated independently with higher odds of hospital death (OR = 5.83, P < 0.001), prolongation of the median hospital stays by 5 days ( P < 0.001), more clinical complications, and increased total hospital charges per admission by $2500. CONCLUSION: AKI is prevalent in cirrhosis patients, and it is associated with increased mortality, hospitalization, and cost. This burden in cirrhosis emphasizes the need for early identification of patients at high risk of AKI and applying prompt and effective management approaches, aiming at improving outcomes.

Development and implementation of interprofessional education activity among health professions students in Jordan: A pilot investigation.

Implementing interprofessional education (IPE) in health professions curricula requires considerations of students' attitudes and readiness. Interventional studies that assess students' perceptions about IPE are needed. As IPE is an emerging concept in Jordan, our study aimed at exploring the attitudes of health profession students about IPE and collaborative practice before and after implementing an IPE activity. Students completed the validated Interprofessional Attitudes Scale (IPAS) before and after completing a 3-hour interprofessional activity. Students' attitudes toward IPE were compared using the subscales and total IPAS scores. A total of 41 health profession students attending the professional health programs of Doctor of Pharmacy, Medicine, Nursing, Nutrition, or Pharmacy completed IPAS before and after conducting the interprofessional activity. Students reported positive attitudes toward IPE prior to the activity. Significant increases were observed in IPAS scores from pre- (median [interquartile range: IQR] score = 4.19 [0.61]) to post-activity (median [IQR] = 4.48 [0.65]), and in its subscales (teamwork, roles and responsibilities, diversity and ethics, and community-centeredness). Students' experience with the IPE activity was positive and optimistic. The findings revealed for the first time the perception and readiness of health profession students toward IPE and collaborative practice in Jordan. This readiness can help draw a path for strategic integration of IPE in health profession curricula.

Clinical Outcomes and Direct Medical Expenditures Associated With Intensive Care Unit Admission for Inpatients With COVID-19 in Jordan: A Retrospective Cohort Study.

OBJECTIVES: This study aimed to describe clinical outcomes and medical expenditures associated with COVID-19 admissions. In addition, this study aimed to investigate the impact of patients' characteristics and baseline comorbidities on intensive care unit (ICU) admission, mortality, and medical expenditures for hospitalized patients with COVID-19. METHODS: This retrospective cohort study included all hospitalized patients with confirmed COVID-19 in Prince Hamza Hospital and King Abdullah University Hospital, during the period from March 2020 to June 2021. Medical records and pharmacy data were followed and reviewed throughout their admissions. The ICU admission, inpatient mortality, hospital length of stay, and inpatient charges were described. Predictors of ICU admission and inpatient charges were evaluated. RESULTS: A total of 7694 COVID-19 hospital admissions were included. Approximately 1189 patients (15.5%) were admitted to ICU and 21.4% died in the hospital. The fatality rate among those admitted to ICU was 82.6% compared with 10.2% for non-ICU admitted patients. The average admission charge and charge per admission day were 1598.2 and 200.2 Jordanian dinar, respectively, and both charges were higher in ICU admitted patients than non-ICU admitted patients. Being older in age, smoker or ex-smoker, and having chronic diseases were all significantly associated with a higher likelihood of ICU admission and mortality among admitted patients. CONCLUSIONS: ICU admission in patients with COVID-19 is associated with poor clinical outcomes and substantial medical expenditures and is more likely among older adults, smokers, and those with chronic diseases.

Comparison of two self-report scales to assess anxiety and depressive symptoms in hemodialysis patients.

INTRODUCTION: Psychiatric illness is prevalent among hemodialysis (HD) patients. This study compared the assessment of anxiety and depressive symptoms among HD patients using two self-administered scales; hospital anxiety and depression scale (HADS) and brief symptom inventory (BSI). METHODS: A cross-sectional study was conducted among a convenience sample of HD patients (n = 352) from different dialysis centers in Jordan. Patients were interviewed in dialysis units, and demographics, clinical status, disease, and dialysis history data were collected. Symptoms of anxiety (HADS-A ≥ 8 and BSI-A ≥ 0.82) and depression (HADS-D ≥ 8 and BSI-D ≥ 0.82) were also measured. RESULTS: The mean age of participants was 52.2 ± 15.6 years. The majority had been receiving HD three times daily and for >2 years. A significant moderate-strong correlation was observed between HADS-A and BSI-A (r = 0.753, p < 0.0001) as well as HADS-D and BSI-D (r = 0.588, p < 0.0001). Anxiety prevalence was 43.7 % using HADS-A ≥ 8 and 80.7 % using BSI-A ≥ 0.82, while depression prevalence was 53.1 % using HADS-D ≥ 8 and 51.7 % using BSI-D ≥ 0.82. When HADS was used as a standard, the operating characteristics reveal that a higher cut-off for BSI-A is recommended (≥1.58) for better anxiety screening. DISCUSSION: Specific and suitable cut-off points need to be further explored and validated for HADS and BSI scales among patients undergoing dialysis.

Exploring the effects of edaravone in rats with contrast-induced acute kidney injury.

AIMS: Oxidative stress and inflammatory response play a vital role in the pathogenesis of contrast-induced acute kidney injury (CI-AKI). This study investigated the effects of edaravone in rats with CI-AKI. MAIN METHODS: Male Sprague Dawley rats were randomly assigned into four groups (n = 11-14/group): control, edaravone (30 mg/kg/day intraperitoneally (IP)), CI-AKI, and edaravone with CI-AKI. The induction of CI-AKI was performed by dehydration and the administration of contrast media (iohexol) and inhibitors of prostaglandin (indomethacin) and nitric oxide synthesis (L-NAME: N-nitro L-arginine methyl ester). Edaravone was administered for two weeks before the induction of CI-AKI. Serum creatinine and urea, renal oxidative stress and inflammatory biomarkers, and histopathological alterations were evaluated after 48 h of contrast exposure. KEY FINDINGS: Rats with CI-AKI showed a significant increase in serum creatinine and urea. The levels of antioxidant biomarkers including glutathione peroxidase, superoxide dismutase and reduced glutathione were significantly decreased in CI-AKI group versus control. Pre-treatment of rats with edaravone normalized kidney function and protected the kidney from oxidative damage as demonstrated by normalization of previous biomarkers. Furthermore, edaravone partially ameliorated renal histopathological alterations relative to the CI-AKI group, notably in the nephrons. No changes were observed in inflammatory biomarkers including tumour necrosis factor-alpha and interleukin-6 among all groups. SIGNIFICANCE: The current findings suggest that edaravone could be a potential strategy to ameliorate developing CI-AKI possibly by improving renal antioxidant capacity. Further studies are warranted to expand the current understanding of the use of edaravone in the various models of AKI.

The role of clinical pharmacist in enhancing hemodialysis patients' adherence and clinical outcomes: a randomized-controlled study.

BACKGROUND: Adherence to treatment recommendations is challenging in hemodialysis (HD) patients, yet it has been found to be extremely crucial in obtaining positive clinical and health outcomes. AIM: To evaluate the influence of implementing an educational process provided by the clinical pharmacist on HD patients' adherence to treatment recommendations and clinical outcomes. METHOD: A randomized controlled trial was conducted in which patients from three HD units in Jordan were randomly allocated to either an intervention (n = 60) or a control group (n = 60). During a three-month period, the intervention group received a monthly educational approach from a clinical pharmacist with recommendations for improving medication, nutrition, and fluid adherence, whereas the control received standard medical care. The primary outcome was patient adherence to HD-related recommendations. Quality of life (QOL), disease awareness, hospitalization, and changes in biochemicals were secondary outcomes. RESULTS: The final analysis included 114 patients (n = 57/group). In the intervention group, there was a significant improvement in total adherence score versus control (1170.6 ± 44.1 vs. 665.8 ± 220.7, p < 0.001), and adherence to various aspects including episodes/duration of shortening HD, dietary guidelines, fluid restriction, and prescription medications. The clinical pharmacist intervention enhanced patients' QOL and improved awareness and perspective of the disease. Following the intervention, laboratory values for urea, creatinine, phosphorus, and hemoglobin were considerably improved. Additionally, the intervention group had fewer hospitalizations than the control group (0.54 ± 0.07 vs. 0.78 ± 0.26, p < 0.001). CONCLUSION: Providing clinical pharmacy education to HD patients improved adherence behavior and clinical outcomes. This illustrates the importance of clinical pharmacists as interdisciplinary team members in dialysis care. Trial registration This trial has been registered in ISRCTN Register (ISRCTN75517095). https://clinicaltrials.gov/ct2/show/ISRCTN75517095.

Solubilization of a novel antitumor drug ribociclib in water and ten different organic solvents at different temperatures.

OBJECTIVE: This study reports new solubility and physicochemical data for ribociclib (RCB) in water and ten organic solvents including "methanol (MeOH), ethanol (EtOH), isopropyl alcohol (IPA), n-butanol (n-BuOH), propylene glycol (PG), polyethylene glycol-400 (PEG-400), acetone, ethyl acetate (EA), Transcutol-HP (THP), and dimethyl sulfoxide (DMSO)" at 293.2-313.2 K and 101.1 kPa. SIGNIFICANCE: The obtained data are useful for the industrial applications of RCB. METHODS: The solubility of RCB was measured and regressed using "van't Hoff, Buchowski-Ksiazczak λh, the modified Apelblat, and Jouyban models." RESULTS: The overall deviations of <4.0% were recorded for all four models. The maximum mole fraction solubility of RCB was 2.66 × 10-2 in PEG-400 at 313.2 K, however, the lowest one was in the water. The RCB solubility increased with temperature and the order followed in the water and ten different organic solvents was PEG-400 (2.66 × 10-2) > THP (1.00 × 10-2) > PG (5.39 × 10-3) > DMSO (5.00 × 10-3) > n-BuOH (3.23 × 10-3) > acetone (3.11 × 10-3) > IPA (1.58 × 10-3) > EA (1.41 × 10-3) > EtOH (1.37 × 10-3) > MeOH (8.10 × 10-4) > water (2.38 × 10-5) at 313.2 K. The maximum solute-solvent interactions were found in RCB-PEG-400 in comparison with other combination of RCB and solvents. "Apparent thermodynamic analysis" indicated an "endothermic and entropy-driven dissolution" of RCB in water and ten organic solvents. CONCLUSIONS: Based on all these data and observations, PEG-400 can be used as the best co-solvent for RCB solubilization.
