Variables including socio-demographics, biomedical variables, in addition to disease and medication characteristics were collected using medical records and custom-designed questionnaire. Medication adherence was assessed using the 4-item Morisky Medication Adherence Scale. Multinomial logistic regression analysis was performed to identify the factors that are significantly and independently associated with medication non-adherence.Results: Of the 427 participating patients, 92.5% had low to moderate medication adherence. Results of the regression analysis revealed that that patients who had higher education level (OR=3.36; 95% CI 1.08– 10.43; P=0.04) and were not suffering from medication-related side effects (OR=4.7; 95% CI 1.91– 11.5; P=0.001) had significantly higher odds of being in the moderate adherence group. Patients who were taking statins (OR=16.59; 95% CI 1.79– 153.98; P=0.01) or ACEIs/ ARBs (OR=3.95; 95% CI 1.01– 15.41; P=0.04) had significantly higher odds of being in the high adherence group. Furthermore, Patients who were not taking anticoagulants had higher odds of being in the moderate (OR=2.77; 95% CI 1.2– 6.46; P=0.02) and high (OR=4.11; 95% CI 1.27– 13.36; P=0.02) adherence groups when compared to patients who were taking anticoagulants.Conclusion: The poor medication adherence in the present study sheds the light on the importance of implementing intervention programs which focus on improving patients’ perception about the prescribed medications particularly for patients who have low educational levels, receive an anticoagulant, and do not receive a statin or an ACEI/ ARB.Keywords: heart failure, medication adherence, medication necessity, medication concerns, intervention, Jordan

Skin cancer, notably melanoma, poses a significant global health burden, with rising incidence and mortality rates. While therapeutic advancements have improved outcomes, metastatic melanoma remains challenging to treat. This study aims to systematically review systemic treatment options for advanced melanoma, focusing on efficacy and safety in the first-line setting. Through a comprehensive search and meta-analysis of randomized controlled trials conducted from 2013 to 2023, 11 studies encompassing 2816 participants were analyzed. Treatment options included BRAF inhibitors (vemurafenib, dabrafenib), MEK inhibitors (trametinib, cobimetinib), and immune checkpoint inhibitors (ipilimumab). Combined therapy with vemurafenib, cobimetinib, and ipilimumab demonstrated superior overall survival (OS) and progression-free survival (PFS) compared to monotherapy, with a significant odds ratio (OR) of 6.95 (95% CI: 4.25-9.64, p < 0.00001) for OS and 2.49 (95% CI: 1.42-3.56, p < 0.00001) for PFS. Additionally, dabrafenib and trametinib combination therapy showed improved outcomes with favorable tolerability, including a significant reduction in adverse event (AE) risk, with an OR of 2.20 (95% CI: 1.72-2.81). Furthermore, our analysis highlighted vemurafenib-associated dermatological toxicities, emphasizing the need for effective management strategies. The study underscores the evolving treatment landscape in melanoma management, with a potential shift towards immune checkpoint inhibitors in the adjuvant setting, particularly for BRAF-mutated disease. However, limitations in meta-analysis methodologies and the need for long-term investigations into treatment implications on survival and quality of life underscore the importance of continued research., (© 2024.

Uncontrolled blood pressure (BP) has been associated with increased risk of cardiovascular events including heart failure. This study aimed to explore the factors associated with poor BP control among patients with heart failure at two major outpatient cardiology clinics in Jordan. Variables including socio-demographics, biomedical variables, in addition to disease and medication characteristics were collected using medical records and custom-designed questionnaire. The validated 4-item Medication Adherence Scale was used to assess medication adherence. Binary logistic regression analysis was conducted to explore the significant and independent predictors of poor BP control. Regression analysis results revealed that being not satisfied with the prescribed medication (OR = 2.882; 95% CI: 1.458-5.695; P < 0.01), reporting moderate medication adherence (OR = 0.203; 95% CI: 22 0.048-0.863; P < 0.05), not receiving digoxin (OR = 3.423; 95% CI: 1.346-8.707; P < 0.05), and not receiving aldosterone antagonist (OR = 2.044; 95% CI: 1.038-4.025; P < 0.05) were associated with poor BP control. Future interventions should focus on increasing medication satisfaction and enhancing medication adherence, in order to improve BP control among patients with heart failure., (© 2023.

Background Colorectal cancer (CRC) is a global health concern with rising incidence. This study analyzed demographic and clinicopathological factors influencing overall survival (OS) and disease-free survival (DFS) in Jordanian CRC patients. Methodology This retrospective, single-center study collected data from CRC patients at the Royal Medical Services, Jordan, from January 2018 to June 2020. Patient variables included disease stage, stage risk, tumor location, history of chemotherapy, and metastasis status. OS and DFS were defined as the time from surgery to death, last follow-up, or metastasis confirmation. Kaplan-Meier curves and Cox models were used for survival analysis. Results Of 127 CRC patients, 33.3% died during the follow-up period. Most patients were males (55.1%), diagnosed with stage III (55.9%), and classified as high risk (59.2%). Metastasis occurred in 24.4%, and 65.4% received chemotherapy. OS at one, two, and end of the follow-up years was 85.2%, 75.6%, and 66.9%, respectively. Metastasis-free rates were 85%, 78.5%, and 71%, respectively. Multivariate analysis showed that stage III (hazard ratio (HR) = 2.968) and high-risk stage (HR = 2.966) were associated with shorter OS and increased metastasis risk. Right-sided tumors (HR = 2.183) had shorter OS, while chemotherapy recipients (HR = 0.430) had longer OS. Stage III and high-risk stages were strong predictors of mortality, while only stage III and high-risk stages were robust predictors of metastasis. Demographic variables (sex and age) showed no significant associations with survival outcomes. Conclusions Our findings highlight the prognostic significance of disease stage, stage risk, tumor location, and chemotherapy in CRC survival among Jordanian patients. Understanding these factors can guide tailored treatment and improve outcomes., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Alkader et al.)

Patients with heart failure (HF) are generally at higher risk of developing type 2 diabetes and having uncontrolled blood glucose. Furthermore, the prevalence of uncontrolled blood glucose in patients with HF is largely unknown. Identifying the factors associated with poor blood glucose control is a preliminary step in the development of effective intervention programs. The current cross-sectional study was conducted at two major hospitals to explore the factors associated with blood glucose control among patients with heart failure and type 2 diabetes. In addition to sociodemographic, medical records were used to collect medical information and a validated questionnaire was used to evaluate medication adherence. Regression analysis showed that poor medication adherence (OR = 0.432; 95%CI 0.204-0.912; P<0.05) and increased white blood cells count (OR = 1.12; 95%CI 1.033-1.213; P<0.01) were associated with poor glycemic control. For enhancing blood glucose control among patients with HF and diabetes, future intervention programs should specifically target patients who have high WBC counts and poor medication., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 S.

Background: Heart Failure (HF) is a chronic disease associated with life-limiting symptoms that could negatively impact patients' health-related quality of life (HRQOL). This study aimed to evaluate HRQOL and explore the factors associated with poor HRQOL among patients with HF in Jordan., Methods: This cross-sectional study used the validated Arabic version of the Minnesota Living with Heart Failure Questionnaire to assess HRQOL in outpatients with HF visiting cardiology clinics at two public hospitals in Jordan. Variables were collected from medical records and custom-designed questionnaires, including socio-demographics, biomedical variables, and disease and medication characteristics. Ordinal regression analysis was used to explore variables associated with poor HRQOL among HF patients., Results: Ordinal regression analysis showed that the number of HF medications (P < 0.05) and not taking a loop diuretic (P < 0.05) significantly increased HRQOL, while the number of other chronic diseases (P < 0.05), stage III/IV of HF (P < 0.01), low monthly income (P < 0.05), and being unsatisfied with the prescribed medications (P < 0.05) significantly decreased HRQOL of HF patients., Conclusions: Although the current study demonstrated low HRQOL among patients with HF in Jordan, HRQOL has a considerable opportunity for improvement in those patients. Variables identified in the present study, including low monthly income, higher New York Heart Association (NYHA) classes, a higher number of comorbidities, and/or taking a loop diuretic, should be considered in future intervention programs, aiming to improve HRQOL in patients with HF., (© 2023.

Objectives: The Validation of Global Lung Initiative (GLI 2012) equations is required prior to their application in clinical practice in different regions. This study validated the GLI 2012 equations in Middle Eastern preschool aged children, which was not previously conducted., Study Design: Spirometry measures were collected from 765 (54% males) healthy 3 to 5-year-old Jordanian children. z scores, percent predicted values, and frequency of measures below lower limit than normal (LLN) were calculated using GLI 2012 equations for Caucasians and Other or Mixed., Results: The mean of z-scores produced by GLI 2012 equation for Caucasians in FEV 0.75 , FEV 1 , FVC, FEV 1 /FVC% and FEF25-75 in boys were 0.03, 0.02, -0.13, 0.26 and -0.08 respectively, while in girls it was -0.03, 0.01, 0.02, -0.01 and -0.04 respectively, and the mean of z-scores produced by GLI-2012 Other or Mixed equations in FEV 1 , FVC, FEV 1 /FVC% and FEF25-75 in boys were 0.56, 0.51, 0.09 and 0.12 respectively, and in girls it was 0.56, 0.67, -0.22 and 0.18 respectively. The frequency of measures below LLN as produced by Caucasians equation were not significantly different from the expected 5% in any of the spirometry parameters., Conclusion: The GLI 2012 for Caucasians is a reasonable fit for Jordanian preschool aged children., (Copyright © 2021 Elsevier Ltd.

Background: The Coronavirus disease 2019 (COVID-19) pandemic is a major threat to public health and has had a significant impact on all aspects of life. An effective vaccine is the most anticipated resolution. This study aims to evaluate Jordanian intent to be vaccinated. Methods: This is a cross-sectional web-based study. Sample characteristics were gathered, and the participants were classified according to the degree of COVID-19 risk based on the categories of the Centers for Disease Control and Prevention (CDC). Participants' KAP toward COVID-19 were assessed, and two scores were calculated: knowledge score and practice score. The association between different sample characteristics and these scores was identified using binary logistical regressions. The participants' vaccination intention was evaluated and multinomial logistic regression was applied to identify the predictors of vaccination intention. Finally, the reasons behind the participants' vaccination refusal/hesitation were determined and categorized into different groups. Results: 1,144 participants were enrolled in the study (females = 66.5%). 30.4% of the participants were at high risk of COVID-19 complications, and 27.5% were at medium risk. Overall, participants' knowledge of COVID-19 symptoms, transmission methods, protective measures, and availability of cure were high (median of knowledge score = 17 out of 21). High protective practices were followed by many participants (median of practice score = 7 out of 10). 3.7% of participants were infected, and 6.4% suspected they were infected with the COVID-19 virus. 36.8% of the participants answered "No" when asked if they would take the vaccine once it becomes available, and 26.4% answered, "Not sure." The main reasons for the participants' vaccination refusal or hesitancy were concerns regarding the use of vaccines and a lack of trust in them. Conclusion: Participants reported high refusal/hesitancy. Several barriers were identified, and efforts should be intensified to overcome these barriers., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Al-Qerem and Jarab.)

Background: The Global Lung Function Initiative attempted to formulate global all-age lung function equations. The suitability of these equations to Middle Eastern children was never evaluated; this study will evaluate these equations in addition to other regional ones., Methods: Spirometry was conducted for 582 (311 boys) healthy 6- to 13-year-old Jordanian children. z scores, predicted values, percent predicted values, and frequency of records below lower limit than normal (LLN) were calculated for each child using the studied equations., Results: Although none of the studied equations produced a perfect representation of the study data, the GLI 2012 equations for Caucasians were the most suitable., Conclusion: GLI 2012 equations for Caucasians are a reasonable fit for Jordanian school-aged children., (© 2020 Wiley Periodicals, Inc.)

Introduction: The global lung function initiative (GLI) 2012 introduced new multi-ethnic spirometry reference values for numerous ethnicities., Objectives: The aim of this study was to investigate the suitability of the GLI reference values for the adult Jordanian population., Methods: About 1875 (1029 females and 846 males) healthy non-smoking adults were enrolled from several locations in Jordan. Spirometry tests were performed. z-scores and predicted normal values were calculated for each participant using GLI 2012 equations in addition to other local equations from the Middle East., Results: Our results indicated that none of the GLI 2012 or other regional equations studied produced an acceptable fit to our data., Conclusion: A need to formulate a specific equation for the Jordanian population is urgently required to better evaluate their respiratory conditions., (© 2019 John Wiley & Sons Ltd.)

Background: Obesity has become a significant worldwide contributor to morbidity with an alarming increase in the incidence of childhood obesity. Few studies have evaluated parental feeding practices and their impact on child obesity in the Middle East. The Comprehensive Feeding Practice questionnaire (CFPQ; Musher-Eizenman & Holub, 2007) has been validated in different age groups and in different countries, however no previous studies have validated the questionnaire in the Middle East., Method: In this study, 970 children aged 6-12 completed the Arabic translated version of the CFPQ. The height and weight of the children were also measured. Confirmatory factor and exploratory factor analysis were used to evaluate different factor models. An ordinal logistic regression was conducted to evaluate the association between maternal feeding practices and child weight status., Results: Confirmatory analysis of the CFPQ determined that the original 12 factor structure of the questionnaire was not suitable for this sample. The analysis suggested that the most suitable structure was an 11 factors model (CMIN/DF = 2.18, GFI = 0.92, CFI = 0.93, TLI = 0.92 and RMSEA = 0.03) that included Modelling, Monitoring, Child control, Food as a reward, Emotional regulation, Involvement, Restriction for health, Restriction for weight control, Environment, Teach and encourage and Pressure. Of the children tested, 12.6% were obese and 25.1% were overweight. The ordinal regression showed Restriction to health and weight, Emotional regulation and maternal BMI were negatively associated with healthy weight status, while Modelling, Monitoring, Child Control, Environment, Involvement, and Teach and encourage were positively associated with healthy weight status., Conclusion: The Arabic translated version of the CFPQ was validated among the study sample, and the best fit for the model was found to utilize 11 factors. This study indicated that child weight status was associated with maternal feeding practices.
