Employing students' evaluations and tutors' perceptions to evaluate a faculty development program on problem-based learning at the Faculty of Medicine, King Abdulaziz University.

BACKGROUND: Faculty development programs are crucial for promoting continuous learning, enhancing teaching effectiveness, and encouraging professional growth among medical educators. Problem-based learning was introduced as a teaching strategy in our Faculty of Medicine in 2007. Thereafter, several rounds of a faculty development program were conducted to help teachers recognize their role as facilitators and assess areas for improvement. METHODS: We conducted a mixed-methods study with a sample of 284 third-year medical students answering a questionnaire and 21 faculty members participating in focus groups. A validated 13-item questionnaire was used to investigate the students' evaluation of their tutors' performance in problem-based learning. Three sessions were then conducted with faculty members involved in problem-based learning to gain in-depth insights into their experiences and perspectives. RESULTS: The mean performance ranking for tutors awarded by the students was above halfway. There was a significant positive correlation between tutors' performance ranking and all five of the learning approaches examined herein: constructive/active learning, self-directed learning, contextual learning, collaborative learning, and intra-personal behavior (p < 0.05). The data from the focus groups were analyzed under five broad themes: tutors' insights into their strengths and weaknesses, challenges in conducting problem-based learning, tutors' ways of preparing for problem-based learning, feedback, and suggestions for improving problem-based learning workshops. CONCLUSIONS: This study recommends improvements and future directions for advanced program evaluation. Faculty development programs can be tailored to effectively address students and faculty members' goals and needs, which can benefit the teaching and learning process and foster a culture of continuous improvement and professional growth.

The perception and association between depression and academic stress among female undergraduate nursing students: a cross-sectional study.

Introduction: Academic demands and stressors put nursing students at increasing risk of depression. The aims of the study examine the perceived level of depression and academic stress and investigate the association between these variables among nursing students in Saudi Arabia. Methods: A cross-sectional design was used in this study. Data was collected using depression subscale from DASS-21 scale and the Academic Stress Inventory scale. Results: A total of 237 students participated in the study. Nursing students perceived normal to mild levels of depression. Students perceived moderate levels of academic stress in all subscales, except for time management and test stress which were high. All academic stress subscales had a positive statistically significant correlation with depression. The regression model explains 49.0% of the variance in the depression scale and indicated that the main significant predictor of depression is studying in group stress, followed by self-inflected stress, study year, and sleep problem. The mean score of depression for first year students was significantly different than students in other study years. Discussion: Nurse educators should facilitate group formation and teach students about time-management, problem-solving, negotiation, and coping strategies to deal with academic expectations and demanding situations. Understanding the causes, limiting the exposure to negative influences, and seeking support as needed are important. To enhance the quality of sleep, students should maintain a consistent sleep schedule, while avoiding stimulating activities before bedtime. Future research should focus on a longitudinal study and other variables such as quality of life, satisfaction with the quality of teaching, and support from others.

Myco-fabricated silver nanoparticle by novel soil fungi from Saudi Arabian desert and antimicrobial mechanism.

Biological agents are getting a noticeable concern as efficient eco-friendly method for nanoparticle fabrication, from which fungi considered promising agents in this field. In the current study, two fungal species (Embellisia spp. and Gymnoascus spp.) were isolated from the desert soil in Saudi Arabia and identified using 18S rRNA gene sequencing then used as bio-mediator for the fabrication of silver nanoparticles (AgNPs). Myco-synthesized AgNPs were characterized using UV-visible spectrometry, transmission electron microscopy, Fourier transform infrared spectroscopy and dynamic light scattering techniques. Their antibacterial activity against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Klebsiella pneumoniae were investigated. In atrial to detect their possible antibacterial mechanism, Sodium dodecyl sulfate (SDS-PAGE) and TEM analysis were performed for Klebsiella pneumoniae treated by the myco-synthesized AgNPs. Detected properties of the fabricated materials indicated the ability of both tested fungal strains in successful fabrication of AgNPs having same range of mean size diameters and varied PDI. The efficiency of Embellisia spp. in providing AgNPs with higher antibacterial activity compared to Gymnoascus spp. was reported however, both indicated antibacterial efficacy. Variations in the protein profile of K. pneumoniae after treatments and ultrastructural changes were observed. Current outcomes suggested applying of fungi as direct, simple and sustainable approach in providing efficient AgNPs.

Health beliefs of unmarried adult Saudi individuals toward safe marriage and the role of premarital screening in avoiding consanguinity: a nationwide cross-sectional study.

Introduction: Premarital screening (PMS) is an essential global measure that seeks to reduce the occurrence of specific genetic disorders and sexually transmitted diseases common in consanguineous marriages. Due to the lack of a nationwide study, this research was designed to comprehend how unmarried individuals perceive the risks and benefits of PMS. Method: A cross-sectional study was conducted using an online questionnaire distributed through different social media platforms, responses from the native adult population (18-49 years) Saudi Arabia was only included in the study. The questionnaire was based on the Health Belief Model (HBM) to assessing seven different constructs including susceptibility, seriousness, benefits-, barriers-, & cues- to action, self-efficacy, and social acceptance. Data frequency was represented by mean and standard deviation; chi-square and t-tests were conducted for the comparison of independent and dependent variables. A multinomial logistic regression was used to predict factors influencing decisions related to PMS. Results: 1,522 participants completed the survey, mostly 18-25 years old and most of them were women. The majority were single with 85 men and 1,370 women. Most participants (59.6%) believed their parents were related, while 40.5% did not. 122 respondents reported they had to marry within their tribe. Findings revealed significant correlations among all HBM themes, with varying strengths. Notably, a moderate positive relationship was found between the perception of benefits and cues to action, suggesting that enhancing the perceived benefits of PMS could facilitate safe marriage practices. Multinomial regression analysis revealed that demographic factors and health beliefs significantly influence individuals' intentions and behaviors toward PMS and safe marriage. Conclusion: The study concludes that by identifying and addressing barriers, and promoting positive social acceptance, PMS can significantly contribute to preventing genetic diseases and promoting safe marriage practices, although the cross-sectional design limits the establishment of causal relationships and further research is needed.

Exploring medical students' experience of the learning environment: a mixed methods study in Saudi medical college.

BACKGROUND: In medical education, the learning environment (LE) significantly impacts students' professionalism and academic performance. Positive LE perceptions are linked to better academic outcomes. Our study, which was conducted 15 years after curriculum reform at King Saud University's College of Medicine, aimed to explore students' perspectives on their LE and identify areas for improvement. By understanding their experiences, we strive to enhance LE and promote academic success. METHODS: This mixed-method study employed an explanatory sequential approach in which a cross-sectional analytical survey phase was collected first using the Johns Hopkins Learning Environment Scale (JHLES), followed by qualitative focus groups. Findings from quantitative and qualitative methods were integrated using joint display. RESULTS: A total of 653 medical students completed the JHLES. The total average score was 81 out of 140 (16.8), and the average subscale scores ranged from 2.27 (0.95) for inclusion and safety to 3.37 (0.91) for community of peers. The qualitative approach encompasses both inductive and deductive analyses, identifying overarching themes comprising proudness, high expectations and competition, and views about the curriculum. The integration of results emphasizes the need for continued efforts to create a supportive and inclusive LE that positively influences students' experiences and academic success. CONCLUSION: This research offers valuable insights for educational institutions seeking to enhance medical education quality and support systems. Recommendations include faculty development, the cultivation of supportive environments, curriculum revision, improved mentorship programs, and initiatives to promote inclusivity and gender equity.

Overall, this study contributes to the ongoing dialog on medical education, offering a nuanced understanding of the complex factors influencing students' perceptions and suggesting actionable strategies for improvement.

The measured healthy lifestyle habits among Saudi university females in Medina, Saudi Arabia: A cross-sectional study.

Lifestyle plays a crucial role in shaping an individual's health outcomes, we aim to calculate the prevalence of lifestyle habits among female populations in the College of Medicine, Taibah University including poor dietary habits, lack of physical activity (PA), poor coping with stress, and impaired sleep patterns and to find factors that are correlated to them. A cross-sectional study was conducted among Saudi females at the College of Medicine, Taibah University, from January 1 to June 1, 2023. Data were collected through interviewing them using validated questionnaires assessing 5 different lifestyle domains. Statistical analysis was performed using Statistical Package for the Social Sciences version 21.0. A total of 263 cases were interviewed. The mean age was 22 ±â€…8.4 years old. The average sleep quality measured by the Pittsburgh Sleep Quality Index of 2.6 ±â€…1.1, suggesting relative difficulty in sleep quality. A total of 68.6% participated in moderate PA. Dietary habits indicated a high prevalence of consumption of sweets, and fast meals, alongside low intake of fruits and vegetables. Emotional well-being, as assessed by the World Health Organization-5 questionnaire, yielded an average score of 7.8 ±â€…5.7, 58.9% moderate stress, and 8% high perceived stress. Adequate sleep quality is crucial for well-being, necessitating lifestyle modifications, particularly weight management, to address sleep disorders. Varied PA levels (46% meeting recommendations) highlight the need for standardized guidelines and tailored interventions. The high prevalence of unhealthy dietary habits underscores the importance of targeted nutritional interventions. Stress prevalence (40%) emphasizes the need for individualized stress management strategies.

Awareness of audiology and speech-language pathology services among healthcare professionals in Saudi Arabia.

BACKGROUND:  Healthcare professionals are required to work effectively together to deliver the best healthcare services. Without awareness of other healthcare professionals' roles and responsibilities, interprofessional practice (IPP) cannot be optimally achieved. OBJECTIVES:  This study aimed to investigate healthcare professionals' awareness of audiology and speech-language pathology (SLP) services in Saudi Arabia. METHOD:  This cross-sectional descriptive study consisted of two parts. The content of a 20-item paper questionnaire was firstly validated. The full-scale study addressed the aim through distributing questionnaire items among potential participants. Descriptive statistics and chi-square test were used. RESULTS:  A total of 403 participants completed the questionnaires for the main study. Most of the participants were Saudi citizens (84.1%), aged 18 years - 40 years (84.8%) years, and lived in Riyadh region (76.2%). Allied health professionals (40.2%), physicians (22.6%), nursing (15.4%) and dentistry (11.2%) were the main group of participants working mainly at governmental hospitals (69.2%). Of the total participants, 92.6% and 95.3% reported being fully aware of the services provided by audiologists and SLPs, respectively. No statistically significant association between the specialty of participants and their familiarity with the scope of practice for SLPs and audiologists was determined. CONCLUSION:  Our study examined healthcare professionals' awareness of audiology and SLP services and revealed a high level of awareness.Contribution: The existed level of awareness is expected to facilitate IPP and enhance the quality of care. Still, awareness campaigns about audiology and SLP services are needed to address the existing lack of knowledge among some healthcare professionals.

Unraveling morphology, methylation profiling, and diagnostic challenges in BRAF-Mutant pediatric glial and glioneuronal tumors.

OBJECTIVES: To elucidate the relationship between DNA methylation profiling (DMP) and pathological diagnosis (PD) in pediatric glial and glioneuronal tumors with B-Raf proto-oncogene, serine/threonine kinase (BRAF) mutations, addressing their diagnostic challenges. METHODS: This retrospective study, conducted in Saudi Arabia, analyzed 47 cases from the Children's Brain Tumor Network online database using scanned images, next-generation sequencing data, and methylation profiles processed using the Heidelberg methylation brain tumor classifiers v12.5 and v12.8. The data was last access on 10 November 2023. RESULTS: The highest prevalence of BRAF mutations was observed in pilocytic astrocytoma and ganglioglioma. The DMP was consistent with PD in 23 cases, but discrepancies emerged in others, including diagnostic changes in diffuse leptomeningeal glioneuronal tumor and polymorphous low-grade neuroepithelial tumor of the young. A key inconsistency appeared between a pilocytic astrocytoma MC and a glioneuronal tumor PD. Two high-grade astrocytomas were misclassified as pleomorphic xanthoastrocytomas. Additionally, low variant allelic frequency in gangliogliomas likely contributed to misclassifications as control in 5 cases. CONCLUSION: This study emphasized the importance of integrating DMP with PD in diagnosing pediatric glial and glioneuronal tumors with BRAF mutations. Although DMP offers significant diagnostic insights, its limitations, particularly in cases with low tumor content, necessitate cautious interpretation, as well as its use as a complementary diagnostic tool, rather than a definitive method.

Optic disc characteristics on digital fundus photographs in Saudi children.

OBJECTIVES: To assess the optic disc parameters in healthy Saudi children. METHODS: This study recruited 85 children who were medically free, born full-term, cooperative, and aged 3-17 years. The children underwent a thorough ophthalmological examination (visual acuity, refraction post-cycloplegia, fundus photography) at the ophthalmology clinic of King Abdulaziz University Hospital, Jeddah. Fundus photographs obtained by a fundus camera were evaluated by the Retinal Size Tool program. RESULTS: Forty-eight participants were male (56.5%). The mean birth weight was 2.97±0.8 kg and the median gestational age was 39 weeks (range, 37-40 weeks). The median areas of the neuroretinal rim, cup, and optic disc were 1.82 mm2 (range, 0.84-2.83 mm2), 0.47 mm2 (range, 0.18-1.25 mm2), and 2.33 mm2 (range, 1.15-3.52 mm2), respectively. The older age group had smaller neuroretinal areas compared to the younger age groups. The variables demonstrated no apparent correlation to axial length, refraction, or birth parameters. The cup size increased together with the optic disc (r=0.659, p<0.001). Sex and refraction did not correlate with any of the studied factors. CONCLUSION: This study yielded normative data for the optic disc parameters of healthy Saudi children. The data can be used as a reference in the pediatric ophthalmology clinic to aid the identification of optic disc abnormalities.

Seroprevalence of transfusion-transmitted infections among blood donors in Makkah, Saudi Arabia.

INTRODUCTION: Blood donation is vital for healthcare; however, transfusion-transmitted infections (TTIs) pose a serious risk. This study investigated the seroprevalence of TTIs among Saudi blood donors. METHODOLOGY: This retrospective study included male blood donors aged ≥ 18 years who donated blood at Al-Noor Specialist Hospital in Makkah from January 2017 to December 2022. The blood units were screened for hepatitis B surface antigen (HBsAg) and core antibodies (HBc-IgG), hepatitis C antibodies (HCV-Abs), syphilis, HIV-1 antigen/antibody (HIV-1 Ag/Ab), human T-lymphotropic virus 1, 2 (HTLV-1/2), and malaria. RESULTS: There were 40,287 donors with an average age of 44.33 ± 18.12 years, and 62.3% (n = 25103) were Saudis. The overall rate of TTIs seropositivity was 7.4% (n = 2953); HBc-IgG (6.1%; n = 2473) was the most common, followed by HCV-Abs (0.4%; n = 177), and syphilis (0.34%; n = 136). All cases were negative for malaria, whilst HIV and HTLV positive donors were 0.06% (n = 24) and 0.13% (n = 52), respectively. Syphilis was more prevalent among non-Saudis (0.24%; n = 83) than among Saudis (0.1%; n = 53), whereas anti-HBc antibodies seropositivity was significantly higher among Saudi (3.4%; n = 1373) than non-Saudi donors (2.7%; n = 1100). CONCLUSIONS: Hepatitis B virus was the most frequently detected bloodborne pathogen, followed by hepatitis C virus and syphilis. Hepatitis B virus was also more prevalent among Saudi donors, whilst expatriates had higher rates of syphilis. Additional prospective multicenter studies are needed to accurately determine the prevalence of TTIs in Saudi Arabia.

CONCLUSIONS The growing use of ChatGPT in scholarly research offers a chance to promote the ethical and responsible use of artificial intelligence. Future studies ought to concentrate on assessing ChatGPT's clinical results and comparing its effectiveness to those of other ChatGPT and other AI tools.

Assessment of Digital Dentistry Knowledge and Practices Among Dental Students at King Faisal University, Saudi Arabia.

BACKGROUND Digital dental (DD) technologies need to be developed for dental use because of the prominent position that these technologies have recently acquired. This 21-item online questionnaire-based study aimed to assess the understanding of DD methods in 120 undergraduate dental students at King Faisal University, Saudi Arabia (SA). MATERIAL AND METHODS Electronic surveys were sent to 123 dental students at different study phases (basic, preclinical, and clinical). Dental students were requested to answer the questionnaires in accordance with their knowledge, observations, particular experiences, and DD practice. Data were analyzed using descriptive statistics, which involved numerical values and ratios. Then, the associations among study level, knowledge, practice, and study phases were analyzed using chi-square and Fisher's exact tests. RESULTS Completed questionnaires were returned by 120 students. The chi-square test showed significant differences in relation to questions "Do you have any previous knowledge of DD?", "The field that uses DD the most is…", "Does DD provide more precise results than conventional dentistry?", and "Do you know about CAD/CAM?", with P values of 0.006, 0.000, 0.018, and 0.002, respectively. Students at clinical phase exhibited significantly higher levels of knowledge than those at the preclinical phase (P<0.01). With regard to DD practice, 73.3% of students expressed a negative viewpoint, 82.5% stated that DD is essential for the future, and half said that practicing DD will result in improvements in patient satisfaction, time consumed, and level of predictability. CONCLUSIONS Students at basic, preclinical, and clinical phases had good knowledge on DD and were motivated to practice it in future in their workplaces.

Biodegradation of the cyanobacterial toxin anatoxin-a by a Bacillus subtilis strain isolated from a eutrophic lake in Saudi Arabia.

Anatoxin-a (ATX-a) is a neurotoxin produced by some species of cyanobacteria. Due to its water solubility and stability in natural water, it could pose health risks to human, animals, and plants. Conventional water treatment techniques are not only insufficient for the removal of ATX-a, but they also result in cell lysis and toxin release. The elimination of this toxin through biodegradation may be a promising strategy. This study examines for the first time the biodegradation of ATX-a to a non-toxic metabolite (Epoxy-ATX-a) by a strain of Bacillus that has a history of dealing with toxic cyanobacteria in a eutrophic lake. The Bacillus strain AMRI-03 thrived without lag phase in a lake water containing ATX-a. The strain displayed fast degradation of ATX-a, depending on initial toxin concentration. At the highest initial concentrations (50 & 100 µg L- 1), total ATX-a degradation took place in 4 days, but it took 6 & 7 days at lower concentrations (20, 10, and 1 µg L- 1, respectively). The ATX-a biodegradation rate was also influenced by the initial toxin concentration, reaching its maximum value (12.5 µg L- 1 day- 1) at the highest initial toxin concentrations (50 & 100 µg L- 1). Temperature and pH also had an impact on the rate of ATX-a biodegradation, with the highest rates occurring at 25 and 30 ºC and pH 7 and 8. This nontoxic bacterial strain could be immobilized within a biofilm on sand filters and/or sludge for the degradation and removal of ATX-a and other cyanotoxins during water treatment processes, following the establishment of mesocosm experiments to assess the potential effects of this bacterium on water quality.

Prevalence, and types of overuse injuries in gym centers: A cross-sectional study in Saudi Arabia.

Physical activity has numerous health benefits, enhancing overall wellbeing. However, it can also lead to injuries, impeding exercise capacity and hindering work. Limited knowledge exists about the prevalence of overuse gym injuries and whether they vary across different gym activities. This study aims to estimate sport injuries at fitness centers in Saudi Arabia, comparing injuries between various activities and session durations. This is a cross-sectional, questionnaire-based study surveyed regular gym-goers in Saudi Arabia with overuse injuries. The online survey, distributed through social media apps, collected data using a validated Google form questionnaire. Questioanire consists of 3 parts. First part of the questionnaire included demographic characteristics of participants. Second part contains characteristics related to gym as gym session's duration, frequency of attending gym per week, sport types, type of injuries and site of injuries. Third part contains Oslo Sports Trauma Research Centre (OSTRC) Overuse injury questionnaire that included 4 questions about difficulties in participation, reduction of training, affection of performance and symptoms. Study included 1012 participants, majority male (76.2%), with age range of 18 to 50 years, and significant proportion falling between 26 and 30 years (52.6%). Majority of participants were from Central Province (42.9%). Gym sessions typically lasted 1 to 2 hours (68.3%), and most common attendance frequency was 4 days/week (39.6%). Common injury sites were shoulder (25.2%), knee (20.2%), and lower back (17.7%). Bodybuilding (50.6%), running (45.8%), and weightlifting/powerlifting (45.1%) were predominant sports. Strain/muscle rupture/tear (35.70%) and muscle cramps/spasm (19.3%) were commonest injury types. Longer gym sessions (>2 hours) were associated with higher prevalence of strain/muscle rupture/tear, dislocation, and subluxation (P < .001). Shorter sessions (<1 hour) had higher prevalence of muscle cramps/spasm and contusion/hematoma/bruise (P < .001). Gym sessions lasting 1 to 2 hours had high prevalence in tendinosis/tendinopathy. Strain/muscle rupture/tear was significantly higher in bodybuilding, weightlifting/powerlifting, swimming, cycling, and running. Tendinosis/tendinopathy was higher in crossfit. (OSTRC) Overuse injury questionnaire revealed decreased participation, training volume, performance, and increased pain with longer gym sessions. In conclusion, gym-related injuries are common, with bodybuilding and running being prevalent activities. Preventative measures should be taken, and individuals are advised to undergo a physical and medical examination before engaging in physical activity at fitness centers.

Systemic immune-inflammation index and its relation to blood pressure and dyslipidemia in adults: A retrospective study.

High blood pressure (BP) and dyslipidemia are major risk factors for cardiovascular disease mortality. The systemic immune-inflammation index (SII) has been suggested as a predictive tool to identify those at risk for chronic diseases, however, its use for predicting high BP and dyslipidemia has not been thoroughly investigated. This study aimed to examine the association between SII and high BP as well as lipid markers. Retrospective hospital data from a large cohort (n = 3895) of Saudi adults aged ≥18 years were analyzed. Lipid markers (cholesterol, high-density lipoprotein, low-density lipoprotein [LDL]), systolic BP, and diastolic BP measures were extracted. When the sample was divided into quartiles of SII, cholesterol, triglycerides, and LDL were higher in those with a higher SII than in those with a lower SII (P < .01). After adjusting for potential confounders, higher SII was significantly associated with higher odds of hypertension (odds ratio: 1.12, 95% confidence interval: 1.04-1.21) and elevated LDL (odds ratio: 1.07, 95% CI: 1.02-1.14), but not with elevated cholesterol. Across quartiles of SII, there was a significant trend between higher SII and the odds of hypertension in people with diabetes and those aged ≥65 years. The SII could be an economical predictive measure for identifying individuals at risk of hypertension and some aspects of dyslipidemia. Longitudinal studies are needed to confirm this relationship.

Prevalence of Zygomatic Air Cell defects in a sample of 6-18-year-old patients in Saudi Arabia and Yemen: a retrospective study.

OBJECTIVES: This study aimed to comprehensively analyze the prevalence and influencing factors of Zygomatic Air Cell Defects (ZACD) among pediatric and adolescent populations in Saudi Arabia and Yemen. MATERIALS AND METHODS: A cross-sectional retrospective study was conducted, utilizing digital panoramic radiographs of dental outpatients aged 6 to 18 years. The data were collected from registered digital databases of dental clinics in Al-Qassim, Saudi Arabia, and an oral and maxillofacial radiology center in Sana'a, Yemen, covering the period from July 2018 to September 2022. The radiographs were evaluated based on inclusion and exclusion criteria, and ZACD was assessed using standardized descriptions. Statistical analysis, including logistic regression, was employed to examine the impact of the associated factors. RESULTS: The study encompassed a total of 3,169 participants, revealing an overall ZACD prevalence of 28.5%. Age emerged as a significant predictor (p ≤ 0.0001), with the likelihood of ZACD increasing as the age of the individual advances. Gender and geographic region did not exhibit statistically significant differences in ZACD prevalence. CONCLUSION: This study provides crucial insights into the prevalence of Zygomatic Air Cell Defects among pediatric and adolescent populations in Saudi Arabia and Yemen. It underscores the prevalence of ZACD and the notable influence of age on its occurrence. Additionally, the research challenges prior notions of gender and regional variations in ZACD prevalence, emphasizing the complexity of the factors involved. Early detection is essential to avoid unwanted complications during any surgical intervention in this area.

Caries prevalence among children at public and private primary schools in Riyadh: a retrospective study.

Dental caries is a global oral health issue, especially critical in children, affecting their growth, nutrition, and education due to school absences or distractions from dental pain. The aim of the study was to investigate the correlation between school types (indicative of socioeconomic conditions) and dental caries prevalence among primary school children in Riyadh, alongside assessing the overall caries prevalence among schoolchildren in Riyadh. Retrospective study on 28,343 first and fourth-grade students from 960 public and private schools in Riyadh, using data from the Saudi Ministry of Health (Feb-April 2019). Utilized the DMFT/dmft index for assessment and collected demographic data. Most of the schools were public (76.1%), private national (17.1%), and private international (6.8%). Overall, the mean DMFT index for permanent teeth and the dmft index for primary teeth were 1.78 and 1.94, respectively. 58% of school children had no dental caries, 25% had mild caries, and 17% had moderate to severe caries. Public school children showed a higher caries prevalence than private schools. Oral disease rates were higher in girls than in boys, and grade four students had a higher prevalence than grade one students. Saudi Arabia, a developing nation, faces challenges in addressing oral health, especially in public schools. Targeted initiatives are crucial for awareness, preventive measures, and meeting oral health needs.

Consensus-based expert recommendations on the management of MPS IVa and VI in Saudi Arabia.

BACKGROUND: Mucopolysaccharidosis type IVa (Morquio A syndrome) and mucopolysaccharidosis type VI (Maroteaux-Lamy syndrome) are rare inherited lysosomal storage diseases associated with significant functional impairment and a wide spectrum of debilitating clinical manifestations. These conditions are thought to have higher-than-average prevalence rates in Saudi Arabia due to high rates of consanguineous marriage in the country. There are several unmet needs associated with the management of these diseases in Saudi Arabia. MAIN BODY: The aim of this manuscript is to contextualize unmet management needs and provide recommendations to optimize diagnosis, multidisciplinary care delivery, and local data generation in this disease area. An expert panel was assembled comprising seven consultant geneticists from across Saudi Arabia. The Delphi methodology was used to obtain a consensus on statements relating to several aspects of mucopolysaccharidosis types IVa and VI. A consensus was reached for all statements by means of an online, anonymized voting system. The consensus statements pertain to screening and diagnosis, management approaches, including recommendations pertaining to enzyme replacement therapy, and local data generation. CONCLUSION: The consensus statements presented provide specific recommendations to improve diagnostic and treatment approaches, promote multidisciplinary care and data sharing, and optimize the overall management of these rare inherited diseases in Saudi Arabia.

Tracking the epidemiological trends of female breast cancer in Saudi Arabia since 1990 and forecasting future statistics using global burden of disease data, time-series analysis.

BACKGROUND: Female breast cancer stands as the prime type of cancer in the Kingdom of Saudi Arabia (KSA), with a high incidence and mortality rates. This study assessed the burden of female breast cancer in KSA by analyzing and forecasting its incidence, mortality, and disability-adjusted life years (DALYs). METHODS: We retrieved data from the Global Burden of Disease (GBD) about female breast cancer from 1990 to 2021. Time-series analysis used the autoregressive integrated moving average (ARIMA) model to forecast female breast cancer statistics from 2022 to 2026. RESULTS: From 1990 to 2021, KSA reported 77,513 cases of female breast cancer. The age groups with the highest number of cases are 45-49 years, followed by 40-44 years, 50-54 years, and 35-39 years. The analysis also showed fewer cases in the younger age groups, with the lowest number in the less than 20-year-old age group. From 1990 to 2021, KSA reported 19,440 deaths due to breast cancer, increasing from 201 cases in 1990 to 1,190 cases in 2021. The age-standardized incidence rate/100,000 of breast cancer increased from 15.4 (95% confidence interval (CI) 11.2-21.0) in 1990 to 46.0 (95%CI 34.5-61.5) in 2021. The forecasted incidence rate of female breast cancer will be 46.5 (95%CI 45.8-46.5) in 2022 and 49.6 (95%CI 46.8-52.3) in 2026. The age-standardized death rate per 100,000 Saudi women with breast cancer increased from 6.73 (95%CI 6.73-9.03) in 1990 to 9.77 (95%CI 7.63-13.00) in 2021. The forecasted female breast cancer death rate will slightly decrease to 9.67 (95%CI 9.49-9.84) in 2022 and to 9.26 (95%CI 8.37-10.15) in 2026. DALYs increased from 229.2 (95%CI 165.7-313.6) in 1990 to 346.1 (95%CI 253.9-467.2) in 2021. The forecasted DALYs of female breast cancer will slightly decrease to 343.3 (95%CI 337.2-349.5) in 2022 reaching 332.1 (95%CI 301.2-363.1) in 2026. CONCLUSIONS: Female breast cancer is still a significant public health burden that challenges the health system in KSA, current policies and interventions should be fashioned to alleviate the disease morbidity and mortality and mitigate its future burden.

Inter-relation between diabetes mellitus and hypertension in terms of incidence and prediction in Saudi Arabia: a retrospective cohort study.

BACKGROUND: Hypertension (HTN) and type 2 diabetes mellitus (T2DM) are interconnected metabolic disorders with escalating global incidence and prevalence. However, no longitudinal studies have specifically examined the incidence of HTN and T2DM in the same study population. This study aimed to elucidate the association between HTN and T2DM and ascertain their respective roles in the development of each other. METHODS: This retrospective cohort study encompassed 809 Saudi patients from primary healthcare centers in Al Madinah Al Munawarah, Saudi Arabia. The sample was stratified into three cohorts: 226 patients with HTN but without T2DM, 274 patients with T2DM but without HTN, and 309 patients devoid of both T2DM and HTN. Over a retrospective follow-up period of approximately 5 years, incidence density rates (IDR) were computed for HTN in the T2DM cohort, T2DM in the HTN cohort, and both HTN and T2DM in the control cohort. Multiple logistic regression analysis was employed to identify predictors of HTN and T2DM. RESULTS: The IDR of T2DM among patients with HTN stood at 73.9 (95% confidence interval [CI] 56, 92) per 1000 person-years, in contrast to 33.9 (95% CI 24, 44) per 1000 person-years in the control cohort (adjusted odds ratio [OR] = 7.1, 95%CI 3.55, 14.13). Conversely, the IDR of HTN among patients with type-2 T2DM was 55.9 (95% CI 42, 70) per 1000 person-years, while in the control cohort, it was 20.8 (95% CI 13, 28) per 1000 person-years (adjusted OR = 5.8, 95% CI 3.11, 11.09). Significant predictors of HTN in the logistic regression model encompassed age, smoking status, family history of HTN, T2DM status, and body mass index (BMI). Similarly, significant predictors of T2DM in the logistic regression model included age, sex, family history of T2DM, HTN, and BMI. CONCLUSION: This study unveils HTN and T2DM as mutually significant risk factors. The IDR of each condition in the presence of the other significantly exceeded that among individuals devoid of HTN or T2DM.
