    Background: End-stage renal disease (ESRD) is the final stage of chronic kidney disease (CKD), characterized by an irreversible loss of kidney function. Globally, the prevalence of ESRD is increasing, resulting in a significant economic and health burden for patients and the health system. This study aims to investigate the impact of medication burden and adherence on health-related quality of life (HR-QOL) for patients who received hemodialysis in the West Bank, Palestine. Methods: A cross-sectional study was conducted to assess HR-QOL through the KDQOL-36TM questionnaire, medication-related burden through the LMQ-3 scale, and medication adherence using the ARMS questionnaire in 120 hemodialysis (HD) patients. The sample was recruited from two dialysis units at the Ministry of Health Hospital (the Palestinian Medical Complex (PMC) in Ramallah and the Hebron Governmental Hospital in Hebron). Results: The majority of HD patients were between 50 and 69 years old (30.8%), resided in villages (62.5%), were married (83.3%), and had a relatively even distribution between males (47.5%) and females (52.5%). The overall HR-QOL global score was 1958.5 (IQR= 2007.50) out of a possible 3600, indicating a moderate level of quality of life. Among the HR-QOL dimensions, symptoms and problems of kidney disease had the highest mean score, while burdens of kidney disease had the lowest. The majority of HD patients (45.8%) experienced a moderate burden. Patient-doctor relationships, effectiveness, and cost-related burden have been shown to be the most significantly influencing factors in medication burden. According to the ARMS scale, the majority of participants (73.3%) had low adherence to their medicine. Correlation tests revealed significant negative relationships between medication-related burden and HR-QOL (R= -0.431, p-value < 0.05), indicating higher medication-related burden is associated with poorer quality of life. Additionally, a positive relationship between medication-related burden and non-adherence (R= 0.61, p-value < 0.05) indicates that higher medication-related burden is associated with higher non-adherence. Conclusion: This study reveals significant insights about the HR-QOL, medication burden, and adherence of HD patients in the West Bank. The study shows that among HD patients, medication burden significantly lowers HR-QOL and increases medication non-adherence. The findings highlight the importance of addressing medication burden as a component of comprehensive treatment to improve patients' quality of life and enhance medication adherence among HD patients.

    The synthesis and characterization of a novel azo dye derived from naphthionic acid and salicylhydroxamic acid are presented in this research. The synthesis process involves the diazo coupling reaction between naphthionic acid and salicylhydroxamic acid, forming the azo dye. The chemical structure and purity of the synthesized dye are confirmed using various characterization techniques, including ultraviolet visible spectroscopy (UV-Vis), infrared spectroscopy (IR), nuclear magnetic resonance (NMR), and high-performance liquid chromatography (HPLC). The properties of the newly synthesized azo dye, such as color, solubility, reactivity, and antimicrobial activity are thoroughly investigated. The dye exhibits a unique color profile and solubility in polar solvents. The reactivity of the dye allows for potential modifications and derivatizations to enhance its versatility. This research provides valuable insights into the synthesis, characterization, and properties of the novel azo dye, offering prospects for its utilization in various applications. The main result showed that the azo dye had an antifungal activity but three types of bacteria, Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa were resistant to the dye. Also, from the calculations, the pka was 3.9and the dye could be used as a chemical indicator.In addition, the prepared dye was investigated as an acid-base indicator for its effect in titrimetric analysis using acid-base titration techniques. In basic media, the color changed from pink to orange. The dye acted as an active acid-base indicator, and the color change occurred in the pH range (5-8).

    (Al-Quds University, 2023-05-20) Sujood Theab Nemer Mashaala; سجود ذياب نمر مشاعلة
    The provision of pharmaceutical services to the community and the care of patients are significant responsibilities of pharmacists. It is unclear if the general public completely understands the important role that pharmacists play in the healthcare system. This study aim was to examine general public perception about community pharmacy services, and how satisfied they are with pharmaceutical care services utilizing the health beliefs model (HBM).Methods A cross-sectional study was carried out on a randomly chosen sample population (n = 400) in West Bank from January through June 2022 for a period of six months. A standardized, self-administered questionnaire with 35 items was used to gather information on the respondents' demographics and satisfaction with pharmacy services utilizing (HBM). Results:The response rate of the survey was 87%. The majority of the respondents perceived benefit of utilizing pharmaceutical care services with mean score (24.5 ± 4.6). There was a significant differences between mean perceived benefit and perceived barriers (24.5 vs. 17.5, p <0.05). Participants generally did not express a high level of agreement on the four susceptibility-assessing items (mean = 11.55 ± 2.44, range 4-20). However, the four questions measuring perceived severity had better agreement (mean = 13.3 ± 3.0, range 4-20). The participants express modest satisfaction with pharmaceutical services and managing therapy, the mean (± SD) score on the satisfaction scale was (24.1±7.1, range 10 - 50). The items regarding lack of privacy and explain side effects of drugs had the highest dissatisfaction percentages (91% and 55%, respectively). Multiple linear regression demonstrated four variables to be significantly correlated with satisfaction with pharmaceutical care services included perceived susceptibility (β = .157, p = .002), residency (β = -.203, p = 0.001), number of medications (β = -.237, p = .001), and perceived barriers (β = -.132, p = .012). Indicating, that participants with higher number of medication and those perceived susceptibility were more satisfied and those perceived barriers were less satisfied with pharmaceutical care provided by community pharmacies. Conclusion: The majority of the participants express modest satisfaction with pharmaceutical care services. The community pharmacists in ideal position to and have the ability to improve the benefit patients perceive by providing comprehensive pharmaceutical care services and managing medication therapy.

    The Efficiency of FLAIR-Weighted BLADE in image Quality Parameter Correction for Moved Patient
    (Al-Quds University, 2023-03-11) maram mohammad motee ghazawna; مرام محمد مطيع غزاونة
    Magnetic resonance imaging (MRI) is a medical tool that can provide detailed information about the inner structure of a person's body. The use of the fluid-attenuated inversion recovery (FLAIR) sequence in imaging the brain is very useful, as it can help identify subtle changes in the brain's structure and function. Due to the sensitivity of MRI to artifacts, it is not always possible to achieve high-quality imaging. The presence of motion artifacts can affect the overall diagnostic value. In this study dipole filling for k-space (BLADE) was implemented for 46 different images with different motion types including right rotation, left rotation, right bending, left bending, flexion, extension, and combination. In this work, we aimed to measure signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and percentage of signal ghosting (PSG). RADIANT DICOM viewer was used to calculate signal intensity (SI) and its standard deviation (SD), the SD is used as the noise index. ImageQC was used to calculate PSG while these measurements are plotted in Microsoft Excel. In this research, we used a control group of 46 patients who have standard images which use the cartesian filling for k-space for comparing the measurements with standard FLAIR sequence. Results showed using BLADE lead to a significant improvement in SNR, CNR, and ghosting in almost all types of motion while failing to correct ghosting from severe patient motion. The mean value of SNR was 1.08 for the dipole filling (BLADE) sequence and significantly reduced to 0.92 for the routine sequence (p<0.05). While the mean CNR was 0.75 for dipole filling and significantly reduced to 0.49 for routine sequence (p<0.05). Finally, the mean PSG for dipole filling was 0.75 and significantly reduced to 0.18 for routine sequence (p<0.05). In conclusion, the dipole filling sequence enhances SNR, and CNR due to flow and eye motion. Although BLADE reduced ghosting artifacts in most types of motion, BLADE was unable to eliminate ghosting appearance from the severe patient motion.
