Parental Awareness, Attitude, and Acceptability of the Human Papillomavirus Vaccine in Jeddah, Saudi Arabia: An Analytical Cross-Sectional Study.

Background Human papillomavirus (HPV) is a significant public health concern linked to various cancers and genital warts. Despite the availability of effective vaccines, vaccination rates remain suboptimal in many regions. Understanding parental awareness, attitudes, and acceptability of the HPV vaccine is critical for developing targeted interventions to increase vaccination uptake. Objective This study aims to assess parental awareness, attitudes, and acceptability of the HPV vaccine in Jeddah, Saudi Arabia, and identify factors influencing their decision-making regarding HPV vaccination for their children. Methods An analytical cross-sectional study was conducted in Jeddah, Saudi Arabia, in 2023. The calculated sample size was 420 parents. Eligible parents with at least one female child aged from nine to 18 years old were invited to participate in the study. A structured questionnaire was administered to parents, collecting data on demographics, knowledge of HPV and its vaccine, attitudes toward vaccination, and reasons for vaccine acceptability or hesitancy. Descriptive statistics were used to summarize the data, and inferential statistics were applied to identify associations between demographic factors and vaccine acceptability. Results The study included a diverse sample of parents. Approximately 153 (35.9%) of participants believed the HPV vaccine was effective, while 129 (30.3%) felt the benefits outweighed the risks. Common reasons for vaccinating included protection against sexually transmitted diseases (159, 37.3%) and genital cancers (178, 41.8%). Hesitancy was primarily due to fear of adverse effects (141, 33.1%) and insufficient information (84, 19.7%). Statistical analysis revealed significant correlations between vaccine acceptability and parental education level, employment status, and personal vaccination history. Conclusion The findings highlight a moderate level of awareness and acceptability of the HPV vaccine among parents in Jeddah. Educational interventions focusing on vaccine safety and efficacy are essential to address misconceptions and increase vaccination rates. Further research should explore tailored strategies to enhance parental acceptance of HPV vaccination in similar contexts.

Assessment of patients' knowledge and perceptions of MRI scans and safety in Saudi Arabia.

Background: This study was conducted to assess the levels of knowledge about MRI scans and safety measures among patients in Saudi Arabia. Methods: This cross-sectional study was conducted at nine Saudi Arabian hospitals and utilized a questionnaire comprising 22 items that evaluated patients' knowledge regarding MRI scans and safety measures, divided into four sections. The questions encompassed patients' sociodemographic data (A), knowledge about MRI (B), safety measures (C), and communication (D). Descriptive statistics were used to characterize the participant demographics and responses. Results: Out of 446 MRI patients, 60.5% correctly identified that MRI does not involve ionizing radiation, and 78% recognized MRI as a diagnostic tool. Further, 94.2% knew that metal objects are not allowed in MRI rooms. However, 80.3% incorrectly believed that pregnant patients cannot undergo MRI at any time, 57% thought the MRI scanner is turned off when not in use, and 72.6% did not recognize any MRI-compatible devices. About 62% were unaware of the need for kidney function tests with contrast agents, and 43% reported anxiety during MRI scans. Overall, 57% of the patients had limited knowledge of MRI safety, with 39.5% considering their understanding adequate. Educational attainment and employment status were significantly associated with improved MRI knowledge. Most participants sought information from healthcare professionals. Conclusion: This study highlights the need to educate patients about MRI procedures and safety protocols. Significant gaps remain in patients' knowledge, especially regarding safety measures. Higher levels of educational attainment and employment status were linked to greater levels of MRI knowledge, suggesting the importance of targeted educational interventions. Healthcare professionals were the patients' main information sources; nevertheless, comprehensive and accessible information is necessary. Improved communication and training for healthcare providers can enhance patient understanding and experiences during MRI scans.

Assessment of Pregnant Women's Knowledge and Perceptions of Antenatal Ultrasound in Saudi Arabia.

Background: This study aims to evaluate pregnant women's knowledge of antenatal ultrasound in Saudi Arabia and its correlation with demographic factors like age and education to enhance prenatal care. Methods: A cross-sectional study was conducted in six Saudi Arabian hospitals, involving 22 questions split between sociodemographic information and knowledge of antenatal ultrasound. Descriptive statistics were used to characterize the participants' demographics and responses. Additionally, inferential statistics were employed to analyze the relationships and differences among the study variables. Results: Among the 531 pregnant women in the study, most demonstrated a good understanding of antenatal ultrasound, identifying its various uses. Specifically, they recognized its roles in evaluating fetal growth (82.5%), placental location (81.7%), amniotic fluid volume (67%), and fetal morphology (65%), predicting the delivery date (79%), and determining the baby's sex (89%). A majority viewed ultrasound as important (89.3%), safe (82.3%), and tolerable (76.3%) for prenatal care. Additionally, 66.7% felt adequately informed, mainly through clinical staff and doctors. Younger age, lower education, lack of prior ultrasound experience, and first pregnancy were linked to lower knowledge. Approximately 65% were uncertain about the nonionizing radiation properties of ultrasound. Conclusions: The study found that while most pregnant women in Saudi Arabia understand the objectives of antenatal ultrasonography, there are gaps in their knowledge about its nonionizing properties. Younger age, lower education, lack of prior ultrasound experience, and first pregnancy contribute to lower knowledge.

Patient perspectives on ionising radiation exposure from computed tomography in Saudi Arabia: a knowledge and perception study.

The objective of this study was to evaluate patient knowledge and understanding of ionising radiation and dosage, as well as the accompanying risks related to computed tomography scans. A total of 412 outpatients who underwent computed tomography (CT) scans were surveyed to assess their understanding of radiation dose and exposure risks. CT was correctly classified as an ionising radiation by 56.8% of the respondents. More than half of the patients reported that a CT scan increases the probability of inducing cancer. Awareness of varying radiation doses in different CT exams was noted in 75.2% of patients, but only 21.4% reported having discussions with their physician about radiation dose. Gender, age and employment were significantly correlated with knowledge levels. The survey findings indicate a limited understanding of the hazards associated with ionising radiation used in CT scans, highlighting a need for increased awareness and education on radiation protection to ensure informed consent.

Provision of Safe Anesthesia in Magnetic Resonance Environments: Degree of Compliance with International Guidelines in Saudi Arabia.

BACKGROUND: The lack of local guidelines and regulations for the administration of anesthesia in magnetic resonance imaging (MRI) units presents a potential risk to patient safety in Saudi Arabia. Hence, this study aimed to evaluate the extent to which hospitals in Saudi Arabia follow international guidelines and recommendations for the safe and effective administration of anesthesia in an MRI environment. METHODS: This study used a questionnaire that was distributed to 31 medical facilities in Saudi Arabia that provided anesthesia in MRI units. RESULTS: The findings of the study revealed that the mean compliance with the 17 guidelines across the 31 sites was 77%; 5 of the 31 sites (16.1%) had a compliance rate of less than 50% with the recommended guidelines. Only 19.4% of the institutes provided general safety education. Communication breakdowns between anesthesia providers and MRI teams were reported. CONCLUSIONS: To conclude, this survey highlights the status of anesthesia standards in Saudi Arabian MRI units and emphasizes areas that require better adherence to international guidelines. The results call for targeted interventions, including the formulation of specific national anesthesia guidelines for MRI settings. Communication breakdowns between anesthesia providers and MRI teams were reported at a rate of 83.9% during the administration of a gadolinium contrast agent. There were additional breakdowns, particularly for high-risk patients with implants, such as impaired respirators (74.2%), thus requiring further investigation due to potential safety incidents during MRI procedures. While considering the limitations of this study, such as potential biases and the low response rate, it provides a valuable foundation for refining protocols and promoting standardized practices in Saudi Arabian healthcare.

Modification of Dispersin B with Cyclodextrin-Ciprofloxacin Derivatives for Treating Staphylococcal.

To address the high tolerance of biofilms to antibiotics, it is urgent to develop new strategies to fight against these bacterial consortia. An innovative antibiofilm nanovector drug delivery system, consisting of Dispersin B-permethylated-ß-cyclodextrin/ciprofloxacin adamantyl (DspB-ß-CD/CIP-Ad), is described here. For this purpose, complexation assays between CIP-Ad and (i) unmodified ß-CD and (ii) different derivatives of ß-CD, which are 2,3-O-dimethyl-ß-CD, 2,6-O-dimethyl-ß-CD, and 2,3,6-O-trimethyl-ß-CD, were tested. A stoichiometry of 1/1 was obtained for the ß-CD/CIP-Ad complex by NMR analysis. Isothermal Titration Calorimetry (ITC) experiments were carried out to determine Ka, ΔH, and ΔS thermodynamic parameters of the complex between ß-CD and its different derivatives in the presence of CIP-Ad. A stoichiometry of 1/1 for ß-CD/CIP-Ad complexes was confirmed with variable affinity according to the type of methylation. A phase solubility study showed increased CIP-Ad solubility with CD concentration, pointing out complex formation. The evaluation of the antibacterial activity of CIP-Ad and the 2,3-O-dimethyl-ß-CD/CIP-Ad or 2,3,6-O-trimethyl-ß-CD/CIP-Ad complexes was performed on Staphylococcus epidermidis (S. epidermidis) strains. The Minimum Inhibitory Concentration (MIC) studies showed that the complex of CIP-Ad and 2,3-O-dimethyl-ß-CD exhibited a similar antimicrobial activity to CIP-Ad alone, while the interaction with 2,3,6-O-trimethyl-ß-CD increased MIC values. Antimicrobial assays on S. epidermidis biofilms demonstrated that the synergistic effect observed with the DspB/CIP association was partly maintained with the 2,3-O-dimethyl-ß-CDs/CIP-Ad complex. To obtain this "all-in-one" drug delivery system, able to destroy the biofilm matrix and release the antibiotic simultaneously, we covalently grafted DspB on three carboxylic permethylated CD derivatives with different-length spacer arms. The strategy was validated by demonstrating that a DspB-permethylated-ß-CD/ciprofloxacin-Ad system exhibited efficient antibiofilm activity.

Gadolinium-Based Contrast Agents in Pregnant Women: A Literature Review of MRI Safety.

Gadolinium-based contrast agents (GBCAs) are commonly used in magnetic resonance imaging (MRI) to enhance the visualisation and characterisation of the region of interest/lesion. Internal structures are well seen with MRI with good spatial resolution. Although MRI is generally considered safe during pregnancy, concerns have been raised regarding the safety of GBCAs, particularly during the first trimester. Limited studies have been conducted to assess the safety of GBCAs in pregnant women, with conflicting results. A comprehensive literature search was conducted using PubMed, SpringerLink, Medscape, ResearchGate and Wiley Online Library. The search terms included various combinations of MRI, pregnancy, first trimester, gadolinium contrast agents, foetus, risk, and toxicity. The search criteria were articles published in English in the last 20 years and indexed in the MEDLINE or Embase databases. The majority of studies found no definitive evidence that GBCAs are harmful during pregnancy, particularly during the first trimester. Some studies reported no increased risk of adverse outcomes in infants exposed to GBCAs during the first trimester. However, other studies showed inconsistent results. Retrospective cohort studies provided some reassurance regarding the safety of GBCAs when indicated in pregnant women but did not address potential long-term adverse outcomes in infants exposed to GBCAs during gestation. The literature review also highlights the importance of further evaluating the subacute and chronic effects of GBCA exposure in infants. The safety of GBCAs during pregnancy, particularly during the first trimester, remains uncertain. More large-scale, long-term studies are needed to clarify the safety of GBCAs in pregnant women and their potential effects on foetal and neonatal outcomes. Until conclusive evidence is available, healthcare providers should carefully weigh the benefits and risks of using GBCAs during pregnancy and consider alternative imaging modalities, such as non-contrast MRI or ultrasound, when necessary.

Impact of Magnetic Resonance Imaging on Healthcare in Low- and Middle-Income Countries.

Magnetic resonance imaging (MRI) played a significant role in the digital health platforms that influenced and supported modern medicine. However, there is a shortage of MRI in low- and middle-income countries (LMICs). The International Society of Radiology offers a detailed plan for LMICs to advance imaging quality in the global health agenda. The overarching objective of this scoping review was to determine the impact of MRI in healthcare in LMICs. This scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify available evidence. We systematically searched four academic databases for peer-reviewed literature published between 2018 and 2021, namely, Medline, PubMed, Web of Science, and Scopus, as well as Google Scholar as a source for gray literature. The search identified 54 articles. We identified a range of reasons for introducing MRI in LMICs. Nonetheless, some challenges to accepting MRI as a method of healthcare have been reported, including technological, regulatory, and economical challenges. To implement the proposed plan, the involvement of professional and international organizations is considered crucial. The establishment of an International Commission on Medical Imaging under the umbrella of international organizations is suggested and collaboration with other diagnostic disciplines is encouraged to raise awareness of the importance of upscale diagnostics at large and to foster its integration into the care pathway globally.

Safety Survey on Lone Working Magnetic Resonance Imaging Technologists in Saudi Arabia.

PURPOSE: The American College of Radiology (ACR) requires MR personnel not to work alone due to the increased risk of safety issues such as projectiles, aggressive patients, and technologist fatigue. As a result, we intend to assess the current safety of lone-working MRI technologists in MRI departments in Saudi Arabia. MATERIALS AND METHODS: A cross-sectional study using a self-report questionnaire was conducted in 88 Saudi hospitals. RESULTS: A response rate of 64% (174/270) was obtained among the 270 MRI technologists which were identified. The study discovered that 86% of MRI technologists had prior experience working alone. In terms of MRI safety training, 63% of MRI technologists received such training. A question about lone MRI workers' awareness of the ACR's recommendations revealed that 38% were unaware of such recommendations. Furthermore, 22% were misinformed, believing that working alone in an MRI unit is optional or depends on the individual's desire to work alone. Working alone has the primary consequence of being statistically significantly associated with projectile/object-related accidents/mistakes (p = 0.03). CONCLUSION: Saudi Arabian MRI technologists have extensive experience working alone without supervision. Most MRI technologists are unaware of lone working regulations, which has raised concerns about accidents/mistakes. There is a need for MRI safety training and adequate practical experience to raise awareness of MRI safety regulations and policies related to lone working among departments and MRI workers.

Assessment of MRI Safety Practices in Saudi Arabia.

Aim: The aim of this study is to investigate the safety practices used by MRI departments in Saudi Arabia. Methods: A cross-sectional study across 113 private and public hospitals was conducted in Saudi Arabia. A survey questionnaire was designed and sent to 113 MRI units. The questionnaire consisted of 43 items under 14 sections for the assessment of MRI safety practices. These 14 sections are related to (i) MRI and its safety, (ii) MRI usage and its safety, and (iii) safety of the MRI technologists and reporting of adverse effects during the usage. The American College of Radiology (ACR) guidance document on MRI safety practices was used as a template for this survey. Data were analyzed using IBM SPSS Statistical software for Windows version 26.0 (IBM Corp., Armonk, NY, USA). Results: Of the 43 items assessed, only 3 items' binary responses (Yes & No) did not differ much. A greater proportion of positive responses for 40 items (93%) regarding MRI safety practices. More than 50% of the participants claimed that their departments lacked a Magnetic Resonance Safety Officer (MRSO). Regarding regular safety training programs, less than 50% received training in MRI safety. Handheld metal detectors were found in only 39% of the MRI units. Conclusion: The majority of MRI units in Saudi Arabia have demonstrated compliance with majority of ACR MRI safety recommendations; nonetheless, there are two main items for which the guidelines may not be attained: MRSO and regular MRI safety training programs. By taking into account the limitations of this study, it is strongly recommended to assign MRSO and implement annual MRI safety training to improve MRI safety practices for both patients and healthcare workers.

Assessment of Patient Knowledge Level Towards MRI Safety Before the Scanning in Saudi Arabia.

Purpose: Magnetic resonance imaging (MRI) is an important diagnostic method in modern clinical medicine. Patients' knowledge about MRI is of utmost importance for optimizing the workflow, safety, and patient comfort and saving valuable time for the MRI department. This study investigates patient knowledge levels regarding MRI safety before an MRI examination. Patients and Methods: A cross-sectional survey was completed by 200 patients who required MRI. Recruitment occurred over eight weeks in governmental and private hospitals in Saudi Arabia; both hospitals and participants were selected randomly. The questionnaire was given to the patients prior to their MRI scans. Descriptive statistics and chi-square tests were performed to identify relationships between knowledge of MRI safety and selected demographic groupings (age, gender, education level, income level). It also evaluates their source of information and assesses the patient's previous experience regarding MRI scans. . Results: The study sample consisted of 200 patients from 230 surveys distributed in Saudi Arabia, and the response rate was ~ 87%. Depending on the P-values of the chi-square statistical test to find the relationship between socio-demographic factors and patient' knowledge level, the results showed a significant association (p-value=0.006) between age and gender and the level of knowledge relating to MRI safety issues. A similar significance (p-value=0.042) is observed between the knowledge level of patients and their educational level and annual income. In addition, a highly significant association (p-value<0.001) is found between education level or previous experience and whether people seek information about MRI safety. Conclusion: The study findings suggest that a complex combination of factors affects patient knowledge regarding MRI safety before an MRI examination. Hence, the hospital and radiological department must provide the patient with accurate information about MRI. .

Improving cervical spinal cord lesion detection in multiple sclerosis using filtered fused proton density-T2 weighted images.

Background: Magnetic Resonance Imaging (MRI) is considered a vital in depicting multiple sclerosis (MS) lesions. Current studies demonstrate that proton density (PD) weighted images (WI) are superior to T2 WI in detecting MS lesions (plaques) in the spinal cord. Purpose: To evaluate the diagnostic value of filtered fused PD/T2 weighted images in detecting cervical spinal cord MS lesions. Material and Methods: In this retrospective study, we selected a sample size of 50 MS patients. Using contrast limited adaptive histogram equalization (CLAHE), a digital image processing filter was used on the (PD/T2) fused images. The produced images were inspected and compared to the original PD images by two experienced neuroradiologists using interobserver and intraobserver. An ROI analysis was also performed on the processed and original PD images. Results: The repeatability measurement of the match between the two examinations was highly consistent for both neuroradiologists. The repeatability for both neuroradiologists was 96.05%, and the error measurement was 3.95%. The reproducibility measurement of the neuroradiologist's evaluation shows that the processed images could help to identify lesions better [excellent (84.87%)] than PD images [good (61.19%)]. ROIs analysis was performed on 113 MS lesions and normal areas in different images within the sample size. It revealed an enhanced ratio of 2.2 between MS lesions and normal spinal cord tissue in processed fused images compared to 1.34 in PD images. Conclusion: The processed images of the fused images (PD/T2) have superior diagnostic sensitivity for MS lesions in the cervical spine than PD images alone.

OCCUPATIONAL DOSES TO RADIOGRAPHY INTERNSHIP STUDENTS IN SAUDI ARABIA USING OPTICALLY STIMULATED LUMINESCENCE DOSIMETRY.

This study aimed to estimate a baseline for the effective doses received by radiography internship students in Saudi Arabia. A retrospective study was conducted from 2015 to 2018 to discern the effective dose measurements for a total of 206 students using optically stimulated luminescence dosemeters. Readings were performed using the OSLR-250 Automatic Reader. Data analysis was carried out on 813 readouts. The annual mean effective dose averaged over a period of 4 y was found to be 0.55 mSv, with a standard deviation of 0.34 mSv and a range of 0.14-1.58 mSv. The results show that 92% ($\frac{190}{206}$) of the students received annual effective doses of <1 mSv. No annual dose record exceeded the limits recommended by authorities (20 mSv/y). The study concluded that the applied radiation protection measures along with education and training help create a safe work environment for radiography internship students.
