Abstract
BACKGROUND Cognitive impairment is a hallmark of multiple sclerosis (MS) but is usually an under-recorded symptom of disease progression. Identifying the predictive signatures of cognitive decline in people with MS (pwMS) over time is important to ensure effective preventative treatment strategies. Structural and functional brain characteristics as measured by various magnetic resonance (MR) methods have been correlated with variation in cognitive function in MS, but typically these studies are limited to a single MR modality and/or are cross-sectional designs. Here we assess the predictive value of multiple different MR modalities in relation to cognitive decline in pwMS over 5 years. METHODS A cohort of 43 pwMS was assessed at baseline and 5 years follow-up. Baseline (input) data consisted of 70 multi-modal MRI measures for different brain regions including magnetic resonance spectroscopy (MRS), diffusion tensor imaging (DTI) and standard volumetrics. Age, sex, disease duration and treatment were included as clinical inputs. Cognitive function was assessed using the Audio Recorded Cognitive Screen (ARCS) and the Symbol Digit Modalities Test (SDMT). Prediction modelling was performed using the machine learning package - GLMnet, where a penalised regression was applied to identify multi-modal signatures with the most predictive value (and the least error) for each outcome. RESULTS The multi-modal approach to neuroimaging was able to accurately predict cognitive decline in pwMS. The best performing model for change in total ARCS (tARCS) included 16 features from across the various MR modalities and explained 54 % of the variation in change over time (R2=0.54, 95 % CI=0.48-0.51). The features included nine MRS, four volumetric and two DTI parameters. The model also selected disease duration, but not treatment, as a predictive feature. By comparison, the best model for SDMT included several of the same above features and explained 39 % of the change over time (R2=0.39, 95 % CI=0.48-0.51). Conventional volumetric measures were about half as good at predicting change in tARCS score compared to the best multi-modal model (R2=0.26 95 % CI:0.22-0.29). The clinical interpretation of the best predictive model for change in tARCS showed that cognitive decline could be predicted with >90 % accuracy in this cohort (AUC=0.92, SE=0.86 - 0.94). CONCLUSION Multi-modal MRI signatures can predict cognitive decline in a cohort of pwMS over 5 years with high accuracy. Future studies will benefit from the inclusion of even more MR modalities e.g., functional MRI, quantitative susceptibility mapping, magnetisation transfer imaging, as well as other potential predictors e.g., genetic and environmental factors. With further validation, this signature could be used in future trials with high-risk patients to personalise the management of cognitive decline in pwMS, even in the absence of relapses.

Abstract
BACKGROUND Extraoral and intraoral dental photographs serve as preoperative records and document the entire treatment. Correctly composed orthodontic photographs are crucial for remote diagnosis and may serve as a bulwark against medicolegal challenges. MATERIALS AND METHODS In this prospective study, intraoral frontal photographs of patients with ideal occlusion were taken using two types of lenses (EF-S 18-55 mm f/3.5-5.6 IS STM lens (Canon, Tokyo, JP), SP 90 mm F/2.8 MACRO VC lens (Model F017 Tamron, NY, USA)) and two different ring flash systems (Meike FC-100 Macro Ring LED Light (Meike, China), Macro Ring flash Lite YN-14EX (Yongnuo digital, China)). The combination of lens and flash used was grouped into four groups. Twenty-eight intraoral photographs of patients were taken. An image quality assessment survey was distributed among two groups - 50 orthodontists and 50 other dental specialists. RESULTS The participants were asked to assess all the intraoral images and subjectively score them on a scale of one to ten, with one being very poor and ten being excellent, considering the sharpness, color, brightness, contrast, and overall quality of the image. The general dentists rated the images taken with a 90-mm macro lens and ring flash as the best quality photographs. Images obtained using an 18-55 mm lens and ring LED received significantly lesser scores and were graded good by dentists. CONCLUSION This combination of lens and flash may prove a valuable investment in the long-term aiding in excellent dental images for diagnosis and treatment monitoring.

Abstract
OBJECTIVE The aim of this study was to compare the scanning accuracy of two different intra-oral scanners- MEDIT i500 and TRIOS 3 shape in reproducing orthodontic bracket dimensions. MATERIALS AND METHODS This in vivo cross-sectional study comprised seven subjects with a full complement of permanent dentition without third molars. Complete arch scanning was carried out with two intraoral scanners, such as MEDIT i500, TRIOS 3 shape, after bonding with brackets. The control group consisted of bracket dimensions measured directly by using Vernier calipers before bonding. Bracket dimensions of three-dimensional (3D) images were measured by using OrthoAnalyzer software. The accuracy of intraoral scanning was investigated by comparing bracket dimensions among the three groups using One-way ANOVA and Post-Hoc Tukey HSD test, and by evaluating outcomes for each quadrant and an individual tooth in complete-arch scans. RESULTS When comparing bracket dimensions of 3D images with manual measurements using a traditional Vernier caliper, MEDIT i500 showed no significant difference when compared to the control group (p>0.05) in full arch scanning as well as the quadrant and single tooth scans in complete arch scanning. TRIOS 3 shape showed a significant difference when compared to the control and MEDIT i500 group (p<0.05) for all parameters. CONCLUSIONS MEDIT i500 showed higher accuracy and better reproduction of orthodontic bracket dimensions than TRIOS 3 shape.

Abstract
Medicines are at the core of every health system. The World Health Organization recommends countries develop national medicines policies that guide production, procurement, prescription and provision of medicines so that people can access the medicines they need at prices they can afford, while avoiding irrational use. However, the development of such policies is rarely straightforward. We describe important components of the national medicines policy in Saudi Arabia, which was developed within a broader transformation of the health system and the economy. The new policy formalizes existing best practices, shapes emerging policies and sets a direction for future development in four main areas. First, the policy seeks to consolidate institutional roles to provide greater cohesion; second it aims to reshape procurement and prescribing habits, with a greater focus on cost containment; third, it lays out policies which focus on assuring a secure supply of good-quality medicines, including essential medicines with limited profit potential and new products. Finally, the policy supports the growth of the domestic pharmaceutical industry, including the development of human resources. Many sectors and institutions joined in the development of the medicines policy, which was underpinned by a review of the past and current pharmaceutical context in Saudi Arabia, and good practices globally. The resulting policy was built on evidence and endeavours to give clear direction to the pharmaceutical industry and implementing agencies on rules and requirements, professional norms and institutional roles. At the same time, it maintains flexibility to allow for adaptation in a rapidly evolving institutional landscape.

Abstract
OBJECTIVES The primary objective of this study was to evaluate the effect of an innovative double-layer, single-application desensitizing/whitening technique of potassium nitrate (PN) and hydrogen peroxide (HP) diffusion at different time points. METHODS AND MATERIALS Specimens were prepared from extracted caries-free human molars (n=90). Teeth were randomly assigned into four groups: Group A (HP CTRL) treated with 25% HP for 45 minutes, group B (PN CTRL) received a single-layer treatment of 5% PN for 45 minutes, group C received the double-layer treatment of 5% PN and 25% HP for 45 minutes, and group D received a 3% PN incorporated in a 40% HP gel for 45 minutes. PN and HP concentrations were measured at 5, 15, 30, and 45 minutes using standard chemical kits. Group comparisons were made using a repeated measures analysis of variance (ANOVA) test. Pairwise tests for differences in diffusion were done, using the Tukey adjustment of p values for multiple comparisons. A significance level of 5% was used. RESULTS Group A showed no significant difference in HP diffusion rates between the 5- and 15- minute, 15- and 30-minute, or 30- and 45-minute time points; group D showed a similar trend; however, group C differed significantly at the 5-and 15-minute time points (p=0.0004), at the 15-and 30-minute time points (p=0.0026), and the 30- and 45-minute time points (p=0.0014). For PN diffusion, groups B and C had significantly different levels at the 15-, 30-, and 45-minute time points (p=0.0005, p=0.0002, and p<0.0001, respectively); and at the 15-, 30-, and 45-minute time points, groups D and C had significantly different PN diffusion (p=0.0327, p=0.0004, and p< 0.0001, respectively). Group C had significantly different PN diffusion at the 5- and 15-minute time points (p=0.0004), the 15- and 30-minute time points (p=0.0026), and at the 30- and 45-minute time points (p=0.0014). CONCLUSION The double-layer technique showed superior diffusion of PN into the pulp chamber and did not affect the diffusion of HP when compared to other techniques. The double-layer technique may be suggested as an alternative tooth-whitening treatment to minimize tooth sensitivity.

Abstract
OBJECTIVE It is currently presumptuous that electric cigarettes are less harmful than the conventional ones; this is increasing the consumption of electric cigarettes. Therefore, this study intended to evaluate the periodontal treatment needs among conventional smokers, electronic cigarette smokers and non-smokers. This cross-sectional designed study involved 150 patients with a mean age of 29.88±7.81 years. PATIENTS AND METHODS Among all patients, 50 patients were recruited in each group. The periodontal condition and the treatment need for the patients were assessed using the community periodontal index treatment need (CPITN). Fisher exact test was used to find the significant association of all three groups with the periodontal status and the treatment need. Female patients (12.5%) showed better periodontal status than the male patients (87.5%) and required less complicated periodontal treatment independently from smoking type. RESULTS Furthermore, deeper pocket depth ≥6 mm (75%) has been found among the conventional cigarette smokers whereas the majority of the electric cigarette smokers (50%) have calculus deposition. Thus, 50% of the electric smokers require professional scaling whereas 57.1% of conventional smokers prerequisite complex periodontal treatment. CONCLUSIONS Besides, there was a significant difference (p≤0.05) observed among all groups in periodontal health index and treatment need. Conventional cigarette consumers need more complicated periodontal treatment compared to the patients who consume electric cigarettes.

Abstract
OBJECTIVE The aim of this prospective randomized case-control study was to understand the clinical benefits and effect of honey as a dressing material on palatal wound healing after harvesting free gingival graft (FGG). PATIENTS AND METHODS This prospective randomized case-control study was conducted on a sample of 20 patients with 10 patients in each group. Medihoney dressing material was applied to the donor site in the test group, whereas no dressing material was applied to the control group. All the patients received the same medication (Ibuprofen 600 mg) and post-operative instructions straight away after the surgical procedure. Patients were given the follow-up appointment at first, second and fourth week after the surgery during which the length and the width of the donor site was measured and recorded. RESULTS At first week, a significant difference in the proportion of patients showing the healing of donor site percentage was found to be 56% (both in width and length) for test group vs. 44% (both in width and length) for the control group (p=0.001). At 4-week, the healing of donor site percentage was found to be 86% (in width) and 91% (in length) for test group vs. 14% (in width) and 9% (in length) for the control group, the difference being statistically significant (p=0.001). CONCLUSIONS The result of this current study suggests that the honey dressing material accelerated the wound healing process of the palatal wound after harvesting FGG. It also showed a shorter recovery period along with less post-operative morbidity.

Abstract
Objective: This study aims to translate and validate the 'Smell Diskettes' screening tool from English into Arabic. The significance of this study stems from the lack of reliable and rapid olfaction screening tests available to Arabic speaking patients and healthcare practitioners. Methods: This is a prospective cohort, multi-center study. A forward-backward translation of the olfaction screening test was done to translate the text into Arabic. Data was collected from two groups: a control group (n=125) of which 84 percent were females (n=105) and a mean age of 22.4 of subjectively normosmic individuals from Alfaisal University and a patients group (n=82) of which 35.4 percent females (n = 29) with a mean age of 38.2, all of whom were diagnosed with olfactory disturbances related to rhinological pathologies, from King Abdulaziz University Hospital (KAUH) in Riyadh, Saudi Arabia. One of the limitations we faced due to convenience sampling and COVID-19 pandemic restrictions was the inability to perform a “test-retest” on study subjects. Results: The study included 207 subjects, out of whom 82 (40 percent) were patients from the rhinology clinic at King Abdulaziz University Hospital (KAUH) and 125 (60 percent) were recruited as controls from Alfaisal University. The average olfaction scores for the control group and the patients’ group were 7/8 and 5/8, respectively. Conclusion: This study has determined that the Arabic-language version is a valid and useful instrument used in clinical practice and for research purposes. The development of this tool will allow more patients in Arabic-speaking countries to be screened for olfactory disturbances.

Abstract
BACKGROUND Primary healthcare (PHC) is an essential component of an effective healthcare system. The Kingdom of Saudi Arabia's (KSA) health reforms prioritize tackling the increasing noncommunicable disease burden by prioritizing PHC, centering it as the core of the newly proposed Model of Care. To identify challenges and opportunities to scale up PHC capacity, understanding the current capacity of primary health care centers (PHCC) is critical. A limited number of publications review PHC capacity in KSA, focusing on specific regions/sectors; this paper is a first to examine PHC capacity on a national level. METHODS The study uses a countrywide Facility Survey that collected data in 2018 from 2319 PHCCs, generating information on their characteristics, number of health workers, services provided, and capacity elements captured through the Service Availability and Drug Availability constructed indices. Descriptive analysis was performed by rural-urban classification. Ordinary Least Squares (OLS) regressions were used to understand correlates to health workers and equipment availability. Finally, a logistic regression was fitted for selected services. Regressions controlled for various measures to determine correlates with facilities' capacity. RESULTS On a national level, there are 0.74 PHCCs per 10,000 population in KSA. There are variations in the distribution of PHCCs across regions and within regions across rural and urban areas. PHCCs in urban areas have more examination rooms but lower examination room densities. Offering 24 × 7 services in PHCCs is infrequent and dependency on paper-based medical recording remains common. More urban regions are more likely to offer general services but less likely to offer burn management and emergency services. PHCCs are mostly staffed with general medicine, family medicine, and obstetrics & gynecology physicians, whose numbers are more concentrated in urban areas; however, their densities are higher in rural areas. Finally, psychiatrists and nutritionists are rare to find in PHCCs. CONCLUSIONS Decision-makers need to consider several factors when designing PHC policies. For instance, PHC accreditation needs to be prioritized given its positive correlation with service provision and health workers availability. PHC 24 × 7 operation also needs considerations in rural areas due to the high dependency on PHCCs. Finally, there is a substantial need for improvements in e-health.

Abstract
INTRODUCTION Plastibell is one of the most common disposable devices used for circumcision. The study aims to determine whether changing the thread type from cotton to polypropylene to tie around the Plastibell in neonatal circumcision would result in faster separation of the ring. PATIENTS AND METHODS Prospective, randomized, clinical and biomechanical studies were performed. All circumcisions were performed by a single surgeon. Data collected included anthropometric measures, demographic data, procedure time, complications, parent satisfaction, follow-up, and outcomes. The biomechanical study measured the tensile properties of both threads using a universal testing machine (4465; Instron, Norwood, MA). RESULTS Two hundred full-term, male neonates aged between 24 and 48 h were circumcised using Plastibell. Both groups were similar in gestational age, age at circumcision, body weight, height, head circumference, Apgar score at 1 and 5 min, procedure time, Plastibell size, and parent satisfaction. The subjects were randomized into two groups of 100 neonates each: group I where Plastibell was tied by a cotton thread supplied by the manufacturer and group II where Plastibell was tied by Polypropylene 0. The mean duration for Plastibell fall-off was 8.98 days and 7.74 days in cotton thread and Polypropylene 0, respectively (P-value < 0.001). There was no difference regarding the complications for both groups. The diameters of the cotton and Polypropylene 0 threads were 0.68 mm and 0.35 mm, respectively. The measured tensile strengths of cotton and Polypropylene thread were 180 MPa and 457 MPa, respectively. CONCLUSION Plastibell tied by Polypropylene 0 fell off faster than that tied by cotton thread, with no significant differences in adverse effects or complications. This finding might be relevant for anxious parents and caregivers. Further studies are needed to examine other types and sizes of threads to investigate whether this separation period can be reduced further.
