Effect of Comprehensive Educational Program on Preeclamptic Women's Risk Perception of Cardiovascular Disease, Self-Efficacy, and Adherence to Healthy Lifestyle Behaviors.

PURPOSE: To evaluate the effect of a comprehensive educational program on preeclamptic women's knowledge, risk perception of cardiovascular disease, self-efficacy, and adherence to healthy lifestyle behaviors. PATIENTS AND METHODS: This study employed a pretest-posttest design. One hundred and two women who previously had preeclampsia were enrolled from July 2022 to December 2022 from outpatient obstetrics, gynecology, and family planning clinics. The primary and secondary outcomes were measured at baseline, after eight weeks, and after three months of the educational intervention. The data were analyzed using SPSS version 23, descriptive and inferential statistics, specifically the Chi-square test, independent t-tests, and repeated measures ANOVA. RESULTS: A statistically significant difference was found between the two groups immediately post-intervention and the three-month follow-up, with a significant improvement among the intervention group than control group regarding cardiovascular disease knowledge (p < 0.001), risk perception (p < 0.001), self-efficacy (p < 0.001), and healthy lifestyle behaviors (p < 0.001). There was a statistically significant interaction between group and time regarding total cardiovascular disease risk perception (F = 203.67, p < 0.001, η2 = 0.673), self-efficacy (F = 70.06, p < 0.001, η2 = 0.405), and adherence to healthy lifestyle behaviors (F = 145.08, p < 0.001, η2 = 0.597). CONCLUSION: This study concluded that the comprehensive educational program had a positive effect on improving preeclamptic women's knowledge and risk perception of CVD, self-efficacy, and adherence to healthy lifestyle behaviors following preeclampsia.

From Insights to Impact: Understanding Cancer Screening Choices through Mixed-Methods.

OBJECTIVE: The main objective of this comprehensive mixed-methods investigation conducted in Jordan were to explore and understand men's engagement in cancer screening. METHODS: The research employed a mixed-methods approach, combining a survey with 209 participants and focus group interviews with 30 individuals. The survey involved quantitative data collection methods to gather information on cancer screening participation rates among men in Amman. Focus group interviews were conducted to collect qualitative data on the factors influencing cancer screening utilization among men in Amman. RESULTS: The study revealed a notably low participation rate, with less than 37% of men engaging in cancer screening. The diminished involvement was attributed to several factors, including health illiteracy, language barriers, restricted access to health-related information and screening services, and cultural considerations. CONCLUSIONS: Based on the findings, the research strongly advocates for tailored interventions that are culturally specific. The emphasis is on the importance of training community health workers to address the identified challenges and enhance both cancer prevention awareness and screening accessibility in Jordan.

"Find Your Y": histological differences in early stage (pT) and post-treatment (ypT) oesophageal adenocarcinoma with implications for salvage endoscopic resection.

AIMS: Current guidelines offer limited strategies for managing recurrent/persistent oesophageal adenocarcinoma (EAC). Salvage endoscopic mucosal/submucosal resection (ER) shows promise in oesophageal squamous cell carcinoma, however its success in EAC is limited. We aimed to elucidate histological characteristics influencing salvage ER success in patients with low-stage, pretreated EAC. METHODS: We retrospectively reviewed 272 EAC tumours postoesophagectomy from five US centres and collected clinicopathological data including discontinuous growth (DG), defined as separate tumour foci ≥2 mm from the main tumour. We selected 101 patients with low-stage disease and divided them into treatment-naïve (n=70) and neoadjuvant therapy (n=31) groups. We compared the two groups and differences in clinical, histological and outcome characteristics were identified. RESULTS: In the entire cohort (n=272), DGs were identified in 22% of cases. Multivariate analysis revealed DGs as an independent prognostic factor for recurrence and positive oesophagectomy margins. Lymphovascular invasion (LVI) and background intestinal metaplasia predicted DG presence and absence, respectively. Compared with the treatment-naïve low T-stage subgroup, the pretreated subgroup exhibited higher incidence of poorly differentiated carcinoma (16% vs 46%, p=0.007), larger tumours (14 vs 30 mm, p<0.001), higher tumour, node, metastases stage (7% vs 30%, p=0.004), more nodal disease (7% vs 36%, p<0.001) and frequent DGs (1% vs 13%, p=0.030). CONCLUSIONS: In treated low T-stage EACs, DGs may contribute to suboptimal outcomes following salvage ER. Presence of LVI (as a surrogate for DGs) and poor differentiation in the absence of intestinal metaplasia in biopsy samples may serve as histological poor prognosticators in treated patients with EAC being considered for salvage ER.

Effect of Prostate Cancer Education on Saudi Men: Knowledge, Beliefs, and Screening Intentions.

PURPOSE: To evaluate the efficacy of a prostate cancer educational program in enhancing knowledge, beliefs, and screening intentions among Saudi men. METHODS: A quasi-experimental design with a non-equivalent control group was employed. Participants (n=152) were randomly assigned to either the intervention or control group. Assessments of knowledge, beliefs, and screening intentions were conducted at baseline and one-month post-intervention. Independent samples t-tests were used for data analysis. RESULTS: Significant improvements were observed in the intervention group compared to the control group after one month. The mean score for knowledge increased by 7.72 (p = 0.001). Beliefs regarding susceptibility, severity, and benefits of prostate-specific antigen (PSA) and digital rectal examination (DRE) also improved significantly (p < 0.005). Additionally, health motivation and intention to screen increased (p < 0.005).   Conclusion: Prostate cancer educational programs can effectively enhance knowledge, address beliefs, and promote screening intentions among Saudi men. Implementing these programs holds promise for increasing awareness and reducing the burden of prostate cancer through early detection and timely intervention.

Analyzing Depressive Symptoms Among Elderly Cancer Patients: A Comprehensive Examination of Demographic and Medical Correlates.

OBJECTIVE: This study aimed to explore the relationship between depressive symptoms and demographic as well as health-related variables in elderly individuals diagnosed with cancer. METHODS: A cohort of 50 elderly cancer patients participated in the study. Data collection involved the completion of surveys and assessments encompassing demographic characteristics, medical profiles, levels of depression, cognitive functioning, activities of daily living, and perceived social support. RESULTS: Findings revealed that among the elderly participants, 45% experienced mild depression, 20% exhibited moderate depression, and 5% showed severe depression. Depression levels were found to be linked to marital status (P = 0.03), with widowed individuals reporting the highest depression rates (80%) and single individuals reporting the lowest (4%). Living arrangements were significantly associated with depression (P = 0.012), with participants cohabiting with their partner and children showing lower depression rates (6%) compared to those living solely with their children (40%). Additionally, depression showed a significant correlation with income (P = 0.01), as individuals reporting insufficient income for living expenses displayed higher levels of depression (58%). Furthermore, depression was notably linked to chronic health conditions like diabetes and respiratory ailments (P = .023), with individuals grappling with respiratory issues reporting the highest depression scores. CONCLUSION: Recognizing and addressing factors such as marital status, living situation, income level, and the presence of chronic illnesses hold the potential for healthcare professionals to tailor interventions effectively to meet the specific requirements of this vulnerable demographic. This tailored approach has the capability to contribute significantly to enhancing the overall well-being and mental health outcomes of elderly cancer patients.

Factors Influencing Prostate Cancer Screening Intentions in Lebanese Men.

OBJECTIVE: The objective of this study is to investigate the perceived obstacles and willingness of Lebanese men aged 40 and above to undergo screening for prostate cancer. MATERIAL AND METHOD: A cross-sectional research design was employed. The study utilized a survey questionnaire to collect data on various factors influencing screening behaviors. The research instrument consisted of a comprehensive survey questionnaire that incorporated validated scales to assess barriers to prostate cancer screening, intention to screen, and the International Prostate Symptom Score (IPSS). RESULTS: The study found that the 120 participants had an average IPSS score of 7.20 ± 2.23, most people (70%) had mild symptoms of prostate cancer, whereas others had moderate (20%) or severe symptoms (10%). The majority of the men indicated a low to moderate inclination to undergo screening through Prostate-specific antigen testing, or digital rectal examination (DRE) (PSA), with 76% considering DRE and 70% considering PSA. The main barriers to screening included the dread of receiving distressing outcomes (48%) and a lack of understanding about the screening procedure (54%). The study identified key factors affecting the intention to undergo a prostate cancer screening. Regarding DREs, these factors included the perceived danger of the illness and prior information from doctors about prostate conditions. When it came to the intention to undergo screening through the prostate-specific antigen test (PSA), determinants included the perceived threat of the disease, one's general health perception, and prior information from doctors about prostate-related issues. Additionally, a significant proportion of participants believed that prostate cancer was not a serious illness (56%) and 57% thought DRE was embarrassing. CONCLUSIONS: The participants displayed a low willingness to get screened for prostate cancer. Implementing interventions that focus on increasing awareness of the disease and its associated risks could potentially reduce the barriers and boost participation in prostate cancer screening.

Nurses' Insights and Experiences in Palliative Chemotherapy Care.

OBJECTIVE: The study sought to provide an overview of the perspectives and experiences of Jordanian nurses in the context of caring for patients undergoing palliative chemotherapy. METHODS: A phenomenological qualitative design was used to explore the perspectives and experiences of 11 Jordanian nurses providing care to patients receiving palliative chemotherapy at a governmental cancer care center. RESULTS: The nurses identified two main themes: "Patient Persistence in Hope" and "Positive Impacts of Palliative Chemotherapy." They observed that some patients held onto false hopes of a cure when consenting to palliative chemotherapy, often influenced by family pressure. However, despite acknowledging fatigue as a major side effect, the nurses generally had a positive view of palliative chemotherapy, especially when it improved patients' quality of life or relieved pain. The nurses believed that the patients' resilience and positive attitude during treatment were encouraging. CONCLUSION: To better support patients, the study suggests that nurses should gain a deeper understanding of the significance patients attach to hope in advanced cancer situations to avoid misinterpreting it as denial or false optimism.

Clinical Significance and Prognostic Implications of Discontinuous Growth Pattern in Esophageal Adenocarcinoma: A Multi-Institutional Study.

The significance of discontinuous growth (DG) of the tumor to include tumor deposits and intramural metastasis in esophageal adenocarcinoma (EAC) is unclear. Esophagectomy specimens from 151 treatment-naïve and 121 treated patients with EAC were reviewed. DG was defined as discrete (≥2 mm away) tumor foci identified at the periphery of the main tumor in the submucosa, muscularis propria, and/or periadventitial tissue. Patients' demographics, clinicopathologic parameters, and oncologic outcomes were compared between tumors with DG versus without DG. DGs were identified in 16% of treatment-naïve and 29% of treated cases ( P =0.01). Age, gender, and tumor location were comparable in DG+ and DG- groups. For the treatment-naïve group, DG+ tumors were larger with higher tumor grade and stage and more frequent extranodal extension, lymphovascular/perineural invasion, and positive margin. Patients with treated tumors presented at higher disease stages with higher rates of recurrence and metastasis compared with treatment-naïve patients. In this group, DG was also associated with TNM stage and more frequent lymphovascular/perineural spread and positive margin, but not with tumor size, grade, or extranodal extension. In multivariate analysis, in all patients adjusted for tumor size, lymphovascular involvement, margin, T and N stage, metastasis, neoadjuvant therapy status, treatment year, and DG, DG was found to be an independent adverse predictor of survival outcomes in EAC. DG in EAC is associated with adverse clinicopathologic features and worse patient outcomes. DG should be considered throughout the entire clinicopathologic evaluation of treatment-naïve and treated tumors as well as in future staging systems.

Endoscopic assisted microscopic posterior cordotomy for bilateral abductor vocal fold paralysis using radiofrequency versus coblation.

PURPOSE: To assess the outcomes of endoscopic assisted microscopic posterior cordotomy for bilateral abductor vocal fold paralysis (BAVFP) using radiofrequency versus coblation. METHODS: This was a randomized prospective cohort study that carried out on 40 patients with BAVFP who were subjected to endoscopic/assisted microscopic posterior cordotomy. The patients were randomly allocated into two groups: group (A) patients were operated with radiofrequency, and group (B) patients were operated with coblation. Glottic chink, grade of dyspnea, voice handicap index 10 (VHI10), and aspiration were evaluated pre-operatively and 2 weeks and 3 months post-operatively. RESULTS: There was a significant improvement in the glottic chink and VHI10 scores postoperatively with a non-significant difference between both groups regarding the degree of improvement. In addition, there was a significant improvement of the grade of dyspnea with a non-significant impact on the degree of aspiration in both groups post operatively. There was a lower incidence of oedema and granulation formation in the coblation group but without a statistical significance. CONCLUSION: Both techniques are effective alternatives for performing posterior transverse cordotomy in cases of BAVFP.

Healthcare workers' compliance with the catheter associated urinary tract infection prevention guidelines: an observational study in Yemen.

BACKGROUND: Catheter-associated urinary tract infection is a global problem but it can be prevented with the appropriate implementation of evidence-based guidelines. This study was conducted to assess the level of compliance of healthcare workers with the catheter-associated urinary tract infection prevention guidelines during the insertion of a urinary catheter. METHODS: An observational study using a descriptive cross-sectional design was conducted at Sana'a City hospitals, Yemen. All the nurses and physicians from the governmental, teaching, and private hospitals were eligible to participate in the study. The data collection was performed through convenience sampling from March 2020 to December 2020, using a structured observational checklist prepared specifically for this study. RESULTS: The majority of the urinary catheter insertions were performed by nurses. There were no written policy or procedures for an urinary catheter insertion and no in-service education or training departments in the majority of the hospitals. The overall mean score of compliance was 7.31 of 10. About 71% of the healthcare workers had a high or acceptable level of compliance and 29% had an unsafe level of compliance. Compliance was low for maintaining aseptic technique throughout the insertion procedure, using a single use packet of lubricant jelly, performing hand hygiene immediately before insertion, and securing the urinary catheter once inserted. Factors affecting the healthcare workers compliance were gender, the working ward/unit of the healthcare workers, the availability of a written policy/procedure and a department or unit for in-service education. CONCLUSION: Yemeni healthcare workers' overall compliance was acceptable but it was unsafe in several critical measures. There is an urgent need for developing, implementing, and monitoring national guidelines and institutional policy and procedures for catheter-associated urinary tract infection prevention. Periodical in-service education and training programs and adequate access to the necessary materials and supplies are paramount.

Nurses' assessment and management practices of pain among intensive care patients in King Khalid Hospital, Kharj, Riyadh.

Background: Pain is a disagreeable combination of sensory and emotional sensations. Employing behavioral pain assessment tools is strongly associated with improved identification of pain. Purpose: The main purpose of the study is to investigate Nurses' Assessment and Management Practices of Pain among Intensive Care Patients in King Khalid Hospital, Kharj, Riyadh. Materials and methods: A self-administered questionnaire was employed in a descriptive cross-sectional study. The study focused on nurses employed in the intensive care unit at King Khalid Hospital in Al-Kharj Province. The researchers utilized convenience sampling to recruit participants. Out of the total 48 nurses approached 45 of them provided responses, leading to a response rate of 94%. The Critically Ill questionnaire was utilized to gather information regarding the treatment and evaluation of pain in patients who were in critical condition. Descriptive statistics and inferential statistics were employed to analyze the collected data. Principal results: it was found that 88% of them utilized instruments to evaluate pain in patients who could express themselves. Among these instruments, the numeric rating scale was the most commonly employed. Furthermore, 77% of the nurses (35 in total) used a pain assessment tool for patients who were unable to communicate, with the Adult Nonverbal Pain Scale being the most frequently used tool in this case. The nurses' perception of the significance of pain assessment was positively associated with the regular utilization of pain assessment tools. Additionally, the nurses considered the use of pain assessment tools with patients who could communicate as more important compared to using such tools with patients who could not communicate. Conclusions: Most ICU nurses utilized nurses' pain assessment instruments to assess the discomfort levels of both patients who could communicate and those who couldn't express themselves effectively. By employing such tools, nurses can improve patient outcomes, ensure effective pain management, and demonstrate a high standard of professional care.

Investigating Saudi Nursing Students' Health Beliefs about Testicular Cancer and Testicular Self-Examination: A Cross-Sectional Study Using the Health Belief Model.

INTRODUCTION: Testicular cancer (TC) is a serious health issue, which requires early detection through testicular self-examination (TSE). OBJECTIVES: To investigate Saudi nursing students' health beliefs about TC and TSE using the Health Belief Model (HBM) scale and assess the validity and reliability of the HBM scale. METHODS: This cross-sectional study recruited a convenience sample of 374 nursing students from six nursing colleges in different cities in Saudi Arabia. Data were collected through self-report questionnaires that included demographic and academic information, as well as a valid and reliable HBM scale for TC and TSE. RESULTS: Most participants were single (88.8 %), in their third year of nursing education (43.9 %), had excellent or very good health (83.2%), had no family history of TC (88.9%), and had no medical problems with their testicles (92.8%). The participants had low susceptibility to TC and moderate beliefs about the seriousness of TC. Furthermore, participants reported moderate levels of perceived benefits and health motivation for preventing TC and practicing TSE, but high levels of perceived barriers and low levels of self-efficacy for practicing TSE. The internal reliability (Cronbach's alpha) of susceptibility, benefits and health motivation, seriousness, barriers, self-efficacy, and health motivation and promotion sub-scales was 0.91, 0.89, 0.88, 0.84, 0.67, and 0.65, respectively. Significant relationship between students' performing TSE and their health beliefs about Susceptibility (t=1.93, p=0.04) and Seriousness of having TC (t=2.88, p=0.03), and self-efficacy (t=3.91, p<0.001) and barriers (t=-2.51, p=0.04) to practice TSE. CONCLUSION: The study concluded that Saudi nursing students had moderate levels of health beliefs about TC and TSE, with high perceived barriers and low levels of self-efficacy for practicing TSE.

Health professionals and family members during cardiopulmonary resuscitation: A qualitative study on the experience of witnessing resuscitation in Jordanian critical care units.

BACKGROUND: The interaction between healthcare professionals (HCPs) and family members during cardiopulmonary resuscitation (CPR) in critical care units (CCUs) has received significant attention. In the Arabic region, family members are typically excluded from participating in critical care treatments, despite the cultural and religious significance of their presence. This highlights a lack of policies and research addressing the cultural factors related to family involvement in CPR within this context. OBJECTIVES: The purpose of this study was to explore the nature of the relationship between HCPs and family member relations during CPR in Jordanian CCUs. METHODS: This study employed a qualitative research design. Data were collected through semi-structured interviews with 45 participants, including 31 HCPs and 14 family members of patients who had undergone CPR in Jordan. Data was managed, organized, and thematically analyzed using NVivo. RESULTS: The study revealed three main themes: Family-Witnessed Resuscitation (FWR) through the eyes of HCPs, FWR through the eyes of family members, and the relationship between HCPs and family members during CPR. The last theme has three subthemes: "Looking out for the Patient," "Looking out for Ourselves," and "Looking out for Each Other." These themes highlighted the complex and dynamic relationships between HCPs and family members during CPR in Jordan. Participants emphasized the importance of clear communication, mutual respect, and a collaborative approach to decision-making during CPR. CONCLUSION: The resultant study model uniquely explains the relationship between Jordanian health professionals and family members during CPR, with important implications for clinical practice and healthcare policies regarding family involvement during resuscitation in Jordan. Further research is needed to explore the cultural and societal factors influencing family involvement in resuscitation in Jordan and other Arab countries.

Artificial intelligence reveals features associated with breast cancer neoadjuvant chemotherapy responses from multi-stain histopathologic images.

Advances in computational algorithms and tools have made the prediction of cancer patient outcomes using computational pathology feasible. However, predicting clinical outcomes from pre-treatment histopathologic images remains a challenging task, limited by the poor understanding of tumor immune micro-environments. In this study, an automatic, accurate, comprehensive, interpretable, and reproducible whole slide image (WSI) feature extraction pipeline known as, IMage-based Pathological REgistration and Segmentation Statistics (IMPRESS), is described. We used both H&E and multiplex IHC (PD-L1, CD8+, and CD163+) images, investigated whether artificial intelligence (AI)-based algorithms using automatic feature extraction methods can predict neoadjuvant chemotherapy (NAC) outcomes in HER2-positive (HER2+) and triple-negative breast cancer (TNBC) patients. Features are derived from tumor immune micro-environment and clinical data and used to train machine learning models to accurately predict the response to NAC in breast cancer patients (HER2+ AUC = 0.8975; TNBC AUC = 0.7674). The results demonstrate that this method outperforms the results trained from features that were manually generated by pathologists. The developed image features and algorithms were further externally validated by independent cohorts, yielding encouraging results, especially for the HER2+ subtype.

The Role of Empathy in Jordanian Medical Encounters.

Patients' satisfaction with their clinical visits is a common indicator of the latter's success. Their satisfaction is then reflected in the outcomes of the visit as satisfied patients are more likely to accept their doctor's diagnosis, treatment suggestions, and advice, as well as trust their future arrangements. In addition, this satisfaction then provides doctors with insight into the effectiveness of empathizing with patients and in terms of dealing with them as humans rather than as an illness. Therefore, this study investigated the role of empathy in Jordanian clinical encounters. A conversation analysis approach was conducted to reveal the types and functional accomplishments of empathy. The findings reveal three types of empathy: acknowledgment, pursuit, and sharing experiences and feelings. This study also found that empathy contributes to the success of medical visits as it plays a helpful role in these medical encounters, such as motivating patients to take care of their health, allowing the doctor to claim knowledge of the patient's problem, and allowing the sharing of strong feelings. Moreover, the empathy sequences then lead into the suggestion sequences, which are likely to improve patients' satisfaction. These findings provide insight into the usefulness of deploying empathy in clinical visits, which can be boosted by designing training courses that aim to help raise doctors' awareness of the value of empathy in medical encounters.

The Associations Between Patients' Characteristics and the Quality of Life Among Acute Coronary Syndrome Patients in Jordan: A Cross-Sectional Study.

Introduction: Acute coronary syndrome (ACS) is one of the most significant leading causes of death and disability in the world. The quality of life (QoL) score is used to evaluate the impact of ACS treatments on the patients' physical, emotional, and social functioning. It is considered a significant indicator of the progress of the patients' health status and is useful in predicting patients' needs for continuing, modifying, or changing their treatment plans. Objective: To identify the associations between patients' characteristics and the QoL among ACS patients in Jordan. Methods: A descriptive cross-sectional study was conducted using a convenience sample of 372 participants with ACS from six referral hospitals in Jordan. Results: Jordanian patients with higher educational level and exercise had significant and positive association with QoL (ß = 0.257, p < .001), (ß = 0.191, p < .001), respectively. Also, patients who reported having dyslipidaemia and having unstable angina (UA) had lower score of QoL (ß = -0.165, p < .001), (ß = -0.149, p < .001), respectively. Finally, gender and working status did not significantly appear to have an association with the total QoL. Conclusions: This study sheds light on the importance of increasing the level of patients' awareness about their illness by educating them about it and encouraging them to engage in physical activity programs.

Acute Liver Injury in the setting of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) Syndrome with Cocaine as suspected culprit agent: A case report.

Drug Reaction with Eosinophilia and Systemic Response (DRESS) syndrome is a rare hypersensitivity reaction characterized by rash, fever, lymphadenopathy, and visceral involvement. The liver is frequently involved in DRESS, with increased liver enzymes and hepatomegaly. Over 40 drugs have been implicated in the induction of DRESS, however other illicit substances have also been linked to this. Prompt identification of this syndrome is imperative for management. We report the case of patient presenting with acute liver injury and eosinophilia, who developed a rash meeting criterion for DRESS, with Cocaine as the suspected culprit agent, and was successfully treated with conservative measures.

Upper Gastrointestinal Cancer: Delays in Diagnosis and Treatment Caused by Barriers to Healthcare in the Latino Community.

We report a case of an 81-year-old male immigrant from a Latin American developing country with a high burden of upper gastrointestinal neoplasms, who presented with a small bowel gastrointestinal stromal tumor (GIST) after 2 years of delay in the diagnosis due to multiple barriers to healthcare. The patient presented with a partial intestinal obstruction in an abdominal computed tomography (CT) scan suggestive of a GIST. Surgical resection was performed, and adjuvant therapy was initiated with imatinib (a tyrosine kinase inhibitor) after the diagnosis was confirmed. The patient had a successful outcome. Due to his migratory status, the patient planned to follow up with different health providers in two different countries, which constitutes a common challenge in the immigrant population.

Biodiesel from Dodonaea Plant Oil: Synthesis and Characterization-A Promising Nonedible Oil Source for Bioenergy Industry.

In this work, Dodonaea oil was studied as a potential biodiesel source. Dodonaea (Dodonaea viscosa Jacq.) is an evergreen shrubby plant that thrives in tropical and subtropical conditions. The plant produces high-grade biodiesel in terms of both quantity and quality despite its naturally high fat content. In the transesterification followed by esterification reaction, varied ratios of oil to methanol, constant temperature (60°), reaction duration (1 h), and different catalyst concentrations (0.25-0.75% (w/w) were utilized. A maximum biodiesel yield of 90% was achieved. For fuel characteristic analysis, the prepared biodiesel was specified and compared to ASTM criteria. The chemical composition was verified using analytical techniques such as FT-IR and NMR spectroscopy. As a result of the foregoing, Dodonaea is considered a possible bioenergy source, particularly in the transport sector.
