Title: Auditory and visual processing skills in Maltese children Abstract: Auditory processing (AP) and visual processing (VP) abilities are important for language development, learning, and classroom participation; however, evidence from Malta remains limited. This study investigated AP and VP performance in 8-year-old Maltese children according to gender, primary language, and neurodevelopmental profile. Participants included 83 children: 71 neurotypical (NT) and 12 neurodiverse (ND). AP skills were assessed using a computer-based battery administered via TestFlight, while VP skills were measured using the Motor-Free Visual Perception Test–Fourth Edition (MVPT-4). Language processing was evaluated through a Sentence Imitation Test derived from the Language Assessment for Maltese Children (LAMC). A researcher-developed questionnaire collected demographic and language background data. Data were analysed using descriptive and inferential statistics within an exploratory quantitative framework. Neurodevelopmental status emerged as the strongest determinant of performance, with ND children demonstrating consistently weaker AP and VP outcomes than NT peers. Gender and primary language showed minimal influence. Sentence imitation performance differed according to neurodevelopmental profile but not gender. Findings highlight interactions between perceptual, cognitive, and linguistic processes. Clinically, results support including AP and VP measures in assessment protocols, while educational implications include reducing perceptual load and implementing structured multisensory teaching approaches. This study contributes novel local evidence on perceptual processing in Maltese children within a bilingual context. Description: M.Sc.(Melit.)

Title: The process of informed consent and decision-making in invasive aesthetic procedures Abstract: Background: Informed consent is a key component of ethical, patient-centred healthcare delivery, ensuring individuals are thoroughly informed about the risks, benefits and alternatives of procedures. Given the increasing number of aesthetic procedures being carried out and the limited research on individuals’ understanding of the risks, benefits and alternatives of informed consent in aesthetic procedures, this research study sought to explore the process of informed consent and the decision-making process of individuals undergoing invasive aesthetic procedures. To address this aim, this research study was guided by three objectives; To explore and examine the informed consent process in invasive aesthetic procedures, to explore the decision-making process in invasive aesthetic procedures and to examine how demographic factors influence patients’ understanding of informed consent in aesthetic procedures. Methodology: A parallel convergent mixed-methods design was adopted. Data was collected using a self-developed structured questionnaire, which underwent face and content validation (n=270) and semi-structured interviews (n=8), from individuals who underwent invasive aesthetic procedures. Quantitative data was analysed using descriptive and inferential statistics, while qualitative data was analysed thematically. Data was converged to identify congruencies and discrepancies. Findings: Participants perceived themselves as being less informed about risks and potential complications compared to the benefits of the procedure. However, individuals were overall satisfied with the consent process, suggesting that insufficient risk information did not influence their final decision to undergo the procedure. Furthermore, participants mentioned dissatisfaction with their self-image and low self-esteem as the main factors influencing their decision to undergo an aesthetic procedure, often outweighing concerns about potential risks or complications. Conclusion: The findings suggest that informed consent in invasive aesthetic procedures serves as a useful but not decisive component of decision-making, as choices were also strongly influenced by personal motivations. This highlights the need to improve ethical, patient-centred consent practices that better address risk understanding and underlying patient motivations. Description: M.Sc.(Melit.)

Title: Establishing image quality criteria for lateral knee radiographs Abstract: Introduction Lateral knee radiographs are frequently performed x-ray projections with a high retake rate. A reason for lateral knee radiograph retakes is inconsistent imaging protocols. A variation in the literature exists regarding the image quality criteria required for lateral knee radiographs. Purpose of the study The purpose of the study was to establish an image quality criteria list for lateral knee radiographs. A standardised list would make it easier for radiographers to decide whether an image should be retaken or not. Methodology This study was conducted at a public general hospital in Malta. A prospective research design was used to collect quantitative data. This study was divided into three parts. The first part of the study consisted of the collection of 25 lateral knee radiographs. In the second part, image quality criteria for lateral knee radiographs were drawn up and validated by experts in the field. The third part of the study consisted of the distribution of the research tool to radiographers and orthopaedic surgeons. The participants were asked whether they would keep or retake 25 lateral knee radiographs according to the established criteria. The extent to which every criterion was met was rated using a 4-point Likert scale. The Mann-Whitney test was used to compare mean rating scores provided to every criterion related to image quality in this study. Results A total of 21 participants filled in the research tool. The participants consisted of 16 radiographers and 5 orthopaedic surgeons. Based on the clinical study results, the six main image quality criteria for lateral knee radiographs, in order of importance, obtained from this study were the following: 1. The knee joint is seen in the lateral position as evidenced by the superimposition of the femoral condyles. 2. The patella can be seen in lateral profile with joint space between the patella and femur well demonstrated. 3. The patella is projected clear of the femur. 4. The proximal tibia slightly superimposes the head of the fibula. 5. The knee joint is in the centre of the collimated field. 6. Fat pad and sharp trabecular markings. Conclusions This study identified an image quality criteria list that may assist radiographers when determining if retakes of lateral knee radiographs are necessary or not. However, further research is required by using a larger sample size and conducting the study in different medical imaging departments. Description: B.Sc. (Hons)(Melit.)

Title: Benefits and challenges of the new MR Linac service implemented at the local oncology department : a radiographers’ perspective Abstract: Purpose: This study aimed to investigate the perception of the radiographers on the benefits and challenges associated with the introduction of the magnetic resonance linear accelerator (MR Linac) at the local oncology hospital. Methodology: All radiographers working at the local oncology department were invited to complete a self-designed questionnaire consisting mostly of Likert scale questions ranging from 1 to 5 and some open-ended questions. The radiographers were asked to rate the benefits and challenges of the MR Linac for specific areas. In addition, the radiographers were also asked to indicate their confidence in performing specific tasks, their perceptions on a radiographer-led workflow, and the additional resources required to improve the services. Finally, the radiographers were asked to indicate their confidence in performing specific tasks on the MR Linac and their views on introducing a radiographer-led workflow. The quantitative data was summarized using descriptive statistics, while the open-ended questions were analysed using content analysis. Results: Out of the 26 invited radiographers, 15 completed the questionnaire. The use of ultra-hypofractionation and the reduction of dose to the healthy OARs were identified as the main benefits of this technology, while the prolonged treatment time was identified as the main barrier. The overall level of confidence using the MR Linac was 2.73 +/- 1.22. The radiographers were least confident in managing technical and safety issues and most confident in positioning patients. The majority of the radiographers (53.3%) agreed that a radiographer-led workflow could improve treatment efficiency, provided that this was introduced gradually following adequate training. Contouring software based on artificial intelligence was identified by most radiographers as required to streamline the workflow. Conclusion: Despite challenges faced, radiographers expressed optimism about the integration of this technology in practice. However, more training is required to improve service delivery and facilitate the introduction of a radiographer-led workflow. Description: B.Sc. (Hons)(Melit.)
