    A Systematic Comparative Evaluation of Classical Machine Learning Algorithms for Liver Lesion Classification in Ultrasound Imaging
    (Al- Quds University, 2026-01-14) Aesha Loay Ebrahim Enairat; عائشه لؤي ابراهيم انعيرات
    Liver ultrasound is very popular as it is accessible, safe and inexpensive, but the distinction between benign and malignant liver lesions is still difficult to make, owing to the noise, low contrast, and the overlap of the lesions. The thesis is an evaluation of the performance and generalization of classical machine learning techniques in liver lesion classification with ultrasound images in 3 binary tasks, where one of them is benign-normal, another one is malignant-normal, and the last one is benign-malignant. We merged a localized clinical dataset with a publicly available dataset in Zenodo, which created an original set of 6,791 ultrasound images. By eliminating the duplicate and very similar images to avoid redundancy we were left with a curated set of unique images numbered 2,387. We compared the default preprocessing with contrast enhancement with Contrast Limited Adaptive Histogram Equalization (CLAHE) and tested various traditional classifiers, including ensemble model, support vector machines, linear model, instance-based model as well as probabilistic models. Stratified cross-validation, independent testing and a fully isolated holdout set were used in the evaluation of model performance. The best and consistent performance of the ensemble-based classifiers was observed especially when it came to malignant- normal and benign- normal classification. Conversely, benign-malignant classification was the hardest to carry out because the lesion types had large visual overlaps. The use of CLAHE resulted in better sensitivity and lesion separability of a number of models, and task-specific advantages. On the whole, the findings suggest that classical machine learning pipelines with the proper support of preprocessing and strict validation may be effective in terms of assisting the classification of ultrasound-based liver lesions and may serve as the basis of further advancement.

    Assessing Midwives' Perception and Knowledge Toward Disaster Emergency Management at Southern West Bank Hospitals
    (AL-Quds University, 2025-12-23) Marah Jafar Hassan Humidat; مرح جعفر حميدات
    Background: Disasters lead to a significant threat to maternal and neonatal health, despite skilled midwives' primary role in maternal and neonatal health, limited research in Palestine has examined midwives’ perception and knowledge regarding disaster emergency management. Aim: This study aims to assess the perception and knowledge of midwives towards disasters in emergency management in hospitals across Bethlehem and Hebron, and to explore factors associated with their preparing and hospital readiness. Methods: A descriptive, cross-sectional quantitative approach was employed among 195 midwives working in ten hospitals located in Bethlehem and Hebron in the West Bank. Data were gathered through a structured, self-administered questionnaire containing 61 items across five key domains: knowledge, roles, skills, preparedness, and hospital readiness. Results: Findings revealed that midwives had a moderate level of overall knowledge and perception, with an average score of 3.21. Levels of knowledge and role clarity were higher compared to preparedness and hospital readiness. Higher preparedness scores were significantly associated with advanced education, greater years of experience, and previous participation in disaster-related training (p < 0.05). Moreover, hospitals that regularly implemented drills or training programs demonstrated higher readiness outcomes. Conclusion: Midwives in Bethlehem and Hebron hospitals possess adequate awareness of their roles in disaster situations but remain insufficiently prepared to manage such events effectively. Institutional readiness and continuous training programs are urgently needed to enhance disaster preparedness and strengthen healthcare resilience in Palestine.

    Determinants of healthcare practitioners' adherence to public health directions guidelines regarding notifiable infectious diseases in governmental hospitals in the West Bank
    (Al-Quds University, 2025-08-09) orouba khader kharbish; عروبه خضر سليمان خربيش
    Infectious diseases remain one of the most serious challenges facing health systems worldwide. They pose a direct threat to public health and have the potential to spread rapidly and cause epidemics if not controlled early. Most health systems rely on effective surveillance and monitoring systems based on healthcare providers' commitment to promptly reporting these diseases, enabling rapid response and the implementation of the necessary preventive and therapeutic interventions to limit their spread. In Palestine, the Public Health Laws are responsible for monitoring the implementation of reporting policies. This body has developed comprehensive lists of infectious diseases that must be reported and the reporting procedures for each condition, to ensure the health system's readiness to confront any epidemic or health emergencies. Aim: This study aims to assess the determinants of healthcare practitioners' adherence to the Public Health Directorate's guidelines for reporting notifiable infectious diseases in government hospitals in the West Bank. Methodology: A descriptive cross-sectional study design was employed, consisting of 758 male and female healthcare providers working at the AL-watani Hospital/Nablus, Jericho governmental hospital, and Hebron governmental hospital. The study was conducted by filling out a questionnaire in the three previous hospitals. Data collection took place within these facilities using a structured, self-administered questionnaire, which consisted of two sections: the first related to socio-demographic characteristicscomprising 20 variables.The second section consists of nine determinants of healthcare providers’ compliance with public health directives for reporting communicable diseases in governmental hospitals. Results:In this study, (254) questionnaires were distributed, which were selected using a convenience sample method, including (52) electronic questionnaires, and the rest were distributed on paper to the study sample due to the lack of a high response when distributing the electronic questionnaire. The researcher retrieved (238) questionnaires from them, valid for statistical analysis. The results showed that the paragraphs ranged between high and medium with responds rate(94%), as follows: Good adherence to reporting deadlines achieved the highest mean among the dimensions (3.88) at a rate of (77.7%), reflecting a clear awareness of the importance of timely reporting and disease control efforts. - Personal motivation and commitment were high, with an average of (3.87) and a percentage of (73.28), reflecting personal commitment to reporting. - Knowledge and awareness of reporting guidelines were high, with an average of (3.51) and a percentage of (70.12), reflecting staff familiarity with reporting guidelines. - Institutional policies and support received an average rating of 3.32, which corresponds to 66.35%. This suggests that while guidelines and policies are in place, they may not always be comprehensive or backed by sufficient resources. - Barriers to compliance were rated as average. The most prominent barriers were the lack of clear guidelines with a score of (65.21%), time constraints, and lack of knowledge. Peer influence and organizational culture were rated low, with a mean score of 3.09 (61.78%), indicating a greater need to foster a culture of collective compliance within work teams. - Legal and regulatory factors were rated low, with a mean score of 3.28 (65.67%), as respondents acknowledged the importance of legal compliance, but their knowledge of the legal consequences was relatively weak. External influences were rated as moderate, with an average score of 3.21 (64.20%), with a moderate impact of government policies on individual reporting commitment. General compliance was rated as moderate, with an average score of 3.14 (62.75%), reflecting good overall commitment but in need of additional support and motivation. Conclusion: The study results indicate that healthcare providers possess a good level of knowledge regarding infectious disease reporting guidelines and feel personally motivated to report incidents. Additionally, the findings show that providers generally have positive attitudes toward reporting. These results underscore the critical need for enhanced training initiatives and improved administrative frameworks within healthcare facilities. By strengthening support systems and clarifying reporting procedures, healthcare providers can be better empowered to implement best practices, ultimately contributing to more effective disease surveillance and enhanced public health protection. Keywords:Determinants, adherence, healthcare practitioners, Public Health Directorate guidelines, notifiable infectious diseases, government hospitals, West Bank.

    Prevalence and Risk Factors of Bloodborne Diseases Among Blood Donors in the West Bank (2020–2024)
    (Al-Quds University, 2025-08-09) Nour Hassan Mohammad Al-Nawawreh; نور حسان محمد النواورة
    Blood banks are essential components of the health care system, and patients needing blood transfusions rely on blood donors. However, blood can carry risks for donors, families, recipients, and the community. Bloodborne diseases such as hepatitis B, C, HIV, and syphilis are among the common infections transmitted through various methods. These infections often do not show symptoms in donors, making them a hidden threat to recipients and public health. blood-borne diseases are a significant concern when it comes to blood transfusions. Because of that, blood banks and health departments often do screenings to catch any infections early.Every year, millions of people globally face the risk of catching infections that can be spread through blood transfusions. However, there is limited research on the prevalence of these conditions among blood donors in Palestine. Methodology: A retrospective cohort study was conducted at the Governmental Preventive Medicine Department (PMD) in the West Bank, Palestine, from 2020 to 2024, to assess the prevalence of blood-borne diseases among blood donors and analyze associated risk factors. Result: From 2020 to 2024, a total of 259,998 blood donors were screened, of whom 808 (0.31%) tested positive for blood-borne infections. The prevalence rates were 0.025% for HBV, 0.0053 for HCV,0.006% for HIV and 0% for syphilis. HBV was the most common infection (81% of cases), followed by HCV (17%) and HIV (2%). Male donors and those residing in urban areas were more likely to be infected. The most affected age group for HBV was 34–41 years, while for both HCV and HIV, it was 26–33 years. Statistical analysis revealed a significant association between infection type and both age group (p < 0.001) and sex (p = 0.003). Notably, unprotected sexual contact accounted for 94% of HIV cases, and HBV vaccination coverage among donors remained low at 13.3%. Conclusion:The study showed that blood donors in the West Bank had unexpectedly low rates of HBV, HCV, and HIV, with no reported cases of syphilis. Notably, men, urban residents, and middle-aged donors were more likely to carry infections. The main modes of transmission for these diseases appear to be through unsafe blood transfusion practices and unprotected sexual activity. Overall, there is room for improvement in vaccination coverage for adults over 33 years of age, safety procedure enhancements, and regular follow-up checks to ensure long-term safety.

    "Assessing Antibiotic Prescriptions and Incidence of Urinary Tract Infection in Pregnant Women Attending Primary Health Care in Nablus City – Palestine "
    (Al-Quds University, 2025-08-12) Lara Zahi Adel Khatatba; لارا زاهي عادل خطاطبة
    Urinary tract infections (UTIs) are a common complication during pregnancy, with up to 20% of pregnant women affected. Empirical antibiotic prescribing is frequent, yet often lacks microbiological confirmation, which contributes to the rising incidence of antimicrobial resistance (AMR). In Palestine, limited data exist on the appropriateness of antibiotic use and resistance patterns among pregnant women. Aim: This study aims to assess the appropriateness of existing antibiotic prescribing practices for UTIs among pregnant women within Nablus's primary healthcare system. It also seeks to identify the prevalence of recurrent and antibiotic-resistant UTIs. Methodology: A prospective cohort study was conducted between December 2024 and May 2025 in primary healthcare clinics in Nablus, Palestine. A total of 485 pregnant women were enrolled. Data were collected using structured questionnaires and laboratory analyses, including urine cultures and antibiotic susceptibility testing. Antibiotic prescriptions were evaluated against international guidelines, particularly those from the American College of Obstetricians and Gynecologists (ACOG). Results: Among participants who underwent urine culture (n = 279), 115 (41.2%) had culture-confirmed UTIs. Escherichia coli (38.3%) and Staphylococcus aureus (22.6%) were the most commonly isolated pathogens. Multidrug resistance was observed in 52% of isolates. Empirical antibiotic treatment was common (55.5%), while 77.3% of prescribed antibiotics followed appropriate dosing and duration, with only 22.7% aligned with ACOG-recommended first-line therapies for pregnancy. Among the 120 participants followed for 90 days, recurrent UTI was identified in 18 cases (15%). However, recurrence was not significantly associated with age, income, parity, trimester, or history of abortion. Conclusions: Although empirical prescribing practices generally met standards for dosage and duration, antibiotic selection often diverged from first-line recommendations. The high rate of multidrug resistance underscores the urgent need for improved diagnostic practices and adherence to evidence-based guidelines. Strengthening antimicrobial stewardship in antenatal care is essential to improving maternal outcomes and reducing AMR in resource-limited settings.
