Probable Causative Agents and Demographic Patterns of Encephalitis, Meningitis, and Meningoencephalitis in a Single Tertiary Care Center.

Introduction Encephalitis, meningitis, and meningoencephalitis present significant challenges in clinical management owing to their diverse etiologies and potential complications. A high suspicion index is critical for guiding treatment strategies and improving patient outcomes. Understanding the demographic characteristics and frequency of causes of these conditions is essential to deliver optimized care. Objective This study aimed to investigate epidemiological causes and relative outcomes, including mortality, based on cultures, laboratory investigations, and demographic factors among patients with encephalitis, meningitis, and meningoencephalitis in a Saudi Arabian tertiary care center. Methods A retrospective cross-sectional study was conducted at King Abdulaziz Medical City (KAMC) in Jeddah, Saudi Arabia. Data were collected from patients admitted between April 2016 and December 2022 who met the specified inclusion criteria. Results Among 233 patients, meningitis was the most prevalent diagnosis (65.77%), with bacterial agents being the predominant causative agents (79.74%). Higher mortality was significant with pediatrics <5 years and adults >60 years. Conclusion This study provides valuable insights into the epidemiology and clinical outcomes of central neurological infections based on a Saudi Arabian cohort. These findings underscore the importance of an accurate diagnosis and tailored management strategies. Further studies are warranted to enhance our understanding and to inform more predictable characteristics targeted in optimizing healthcare delivery for patients with such conditions.

Knowledge and Attitude Toward Sciatica Pain and Treatment Methods Among the Population of Qassim in Saudi Arabia: A Cross-Sectional Study.

Background: Sciatica, a pain radiating along the sciatic nerve, can cause significant suffering and functional limitations. Understanding individual populations' knowledge and attitudes about sciatica pain is crucial for designing targeted interventions and enhancing healthcare delivery, especially in Saudi Arabia. This study aimed to evaluate the knowledge and attitude toward sciatica pain and treatment methods among the population of Al-Qassim in Saudi Arabia. Methods and materials:This online cross-sectional study was conducted in the Al-Qassim region, Saudi Arabia, using a self-administered questionnaire. The data was analyzed using SPSS software, with numeric data presented as mean ± SD and categorical variables as frequencies and percentages. Correlation analyses included the Chi-squared test and one-way ANOVA. Results: The study received 398 responses, from mostly female (n=305, 76.6%) and Saudi adults aged under 30 (n=248, 62.3%). Most participants sought treatment for sciatica pain from a specialist doctor (n=28, 56.0%) or a general doctor (n=10, 20.0%). Physical therapy was the most common self-treatment method (n=11, 32.4%), followed by painkillers and muscle relaxants (n=10, 29.4%). Knowledge and attitude toward sciatica were generally low (mean score: 3.54 ± 2.61 out of 9), with only 70 (17.6%) showing good knowledge. Most respondents recognized practices like spinal imaging, surgery as a last resort, and exercise/sitting habits as impacting sciatica outcomes. Traditional therapies like massage, cupping, acupuncture, and cautery were considered beneficial. Educational level significantly impacted knowledge scores, with higher mean scores among postgraduate education holders and bachelor's degree holders (mean scores: 4.06 ± 2.48 and 3.98 ± 2.53, respectively). Age, gender, occupation, nationality, and region showed no significant differences in mean knowledge scores. Attitude scores were similar across sociodemographic spectra, with younger respondents having slightly more positive attitudes.  Conclusion: The study showed poor knowledge, influenced by education levels, and neutral attitudes about sciatica among residents of Al-Qassim. Therefore, educational programs and engagement of healthcare stakeholders are recommended to raise awareness and improve knowledge and attitudes.

SEQUEL: Prevalence of dental caries in Saudi Arabia: A systematic review and Meta-analysis.

This meta-analysis investigated the prevalence of dental caries throughout the Kingdom of Saudi Arabia (KSA) between 2011 and 2023 as a follow-up to a previously published review in 2013 by Khan et al. and aimed to provide an update on the current status of caries prevalence in the KSA. A literature search was conducted, and thirty-three articles were included in the final analysis. To determine the prevalence of caries in primary teeth, the 2- to 12-year-old Saudi population was included in the search, and an age range of 6-18 years was used for permanent teeth. The prevalence of caries in the primary and permanent dentition was analyzed separately. As the included studies for the primary and permanent teeth had insignificant heterogeneity, fixed-effect models and forest plots were used to evaluate caries prevalence in both dentitions. In the primary dentition, the mean decayed-missing-filled teeth (dmft) index was 4.14 (95 % confidence interval (CI): 3.11-5.18), with an average prevalence of 75.43 %. For the permanent teeth, the mean DMFT (uppercase used for permanent dentition) was 1.28 (95 % CI: 0.93-1.64), with an average prevalence of 67.7 %. The average dmft/DMFT scores decreased in both primary and permanent teeth compared to the previous meta-analysis by Khan et al., suggesting a beneficial effect of preventative measures on caries prevalence. Continuing these measures is necessary to maintain the downward trend of caries prevalence in the KSA.

The Effect of Genetic Variants of SLC22A2 (rs662301 and rs315978) on the response to Metformin in type 2 Saudi diabetic patients.

PURPOSE: To investigate the allelic and genotypic frequencies of the two genetic variations, NC_000006.12: g.160275887C > T (rs662301) and NC_000006.12:g.160231826 T > C (rs315978), in the SLC22A2 gene among the Saudi population. The primary goal is to elucidate potential associations with these genetic variations and the response to metformin therapy over 6 months to enhance our knowledge of the genetic basis of Type 2 Diabetes Mellitus (T2DM) and its clinical management in the Saudi population. MATERIALS/METHODS: 76 newly diagnosed T2DM patients, aged 30 to 60, of both sexes and Saudi origin, were treated with metformin monotherapy. Blood samples were collected before and after 6 months of therapy,80 healthy individuals were included as controls. Genomic DNA was extracted. Genotyping of the SLC22A2 genetic variations was performed using TaqMan® SNP Genotyping Assays. Binary logistic regression was utilized to evaluate how certain clinical parameters influence T2DM concerning the presence of SLC22A2 gene variants. RESULTS: Among these patients, 73.3 % were responders, and 26.7 % were non-responders. For these variants, no statistically significant differences in genotype or allele frequencies were observed between responders and non-responders (p = 0.375 and p = 0.384 for rs662301; p = 0.473 and p = 0.481 for rs315978, respectively). For the SLC22A2 variant rs662301, the C/C genotype was significantly associated with increased T2DM risk with age and elevated HbA1c levels. Similarly, rs315978 revealed higher T2DM susceptibility and HbA1c elevation in C/C genotype carriers, specifically with advancing age compared to individuals with C/T and T/T genotypes. CONCLUSION: The study offers insights into the genetic landscape of T2DM in Saudi Arabia. Despite the absence of significant associations with treatment response, the study suggests potential age-specific associations, this highlights the complexity of the disease. This research underscores the necessity for expanded research, considering diverse populations and genetic factors, to develop personalized treatment approaches. This study serves as a foundation for future investigations into the Saudi population, recognizing the need for a larger sample size.

The use of complementary and alternative medicine for functional gastrointestinal disorders among the saudi population.

Background and objective: Complementary and alternative medicine (CAM) is a common practice among patients, who experience functional gastrointestinal disorders (FGID). Among the Saudi population, less is known about CAM use for FGID. Therefore, this study aimed to determine the prevalence of CAM utilization for FGID amongst the Saudi population and determine the types of CAM used for treatment. Method: A cross-sectional study was carried out in Riyadh, Saudi Arabia during February 2023 through social media platforms using questionnaires adopted from the literature. There were three sections in the questionnaire including demographic information, questions to determine the prevalence of CAM use for FGID, the types of FGID, and the types of CAM utilization, and questions on the sources of information about CAM. Multivariable logistic regression was applied to find factors associated with CAM use. All statistical analyses were performed using SPSS version 26. Results: A total of 828 people participated in this study. The overall prevalence of CAM use for FGID problems was 87.2 %. There were no significant differences in CAM use for FGID problems between men (87.5 %) and women (86.3 %) (P = 0.727). The most commonly used types of CAM for FGID were ginger (73.4 %), chamomile (66.6 %), mint (61.6 %), turmeric (59.0 %), anise (55.5 %), fennel (43.1 %), and Activia yogurt©ï¸ (42.7 %). The most common FGID disorders for utilizing CAM were IBS (29.9 %), followed by constipation (29.8 %), dyspepsia (22.7 %), and bloating (17.0 %). In the multivariable regression, age, gender and employment status did not have an impact on the odds of using CAM. The subjects who had high school, university, and postgraduate education had significant odds ratios of CAM use (OR = 2.73; 95 % CI: 1.22-6.13), (OR = 4.18; 95 % CI: 2.03-8.58), and (OR = 20.85; 95 % CI: 5.51-78.80), respectively, compared to subjects who did not complete high school. Participants who had private insurance had a significant odds ratio (OR = 0.27; 95 % CI: 0.14-0.55) compared to governmental insurance. Conclusion: The use of CAM among the Saudi population is alarmingly high; however, the lack of standardized medical recommendations and treatment options may be the cause. Although there were no significant gender differences, participants with higher educational levels and private insurance coverage were more likely to use CAM for FGID. Patients suffering from FGID and limited access to medical advice and treatment options are vulnerable to being exposed to dubious and incredible information sources. Expanding access to preventative medical services, funding governmental medical websites to provide credible information, educating healthcare professionals about FGID, and conducting more research in safe and effective treatments for FGID is recommended.

Knowledge, Perception, and Associated Factors of Electronic Cigarette Consumption Among the Saudi Population in Jeddah City.

Introduction Electronic cigarettes (e-cigarettes) are rising in popularity among young adults and teenagers. Previous studies have shown that among high and middle schoolers, the percentage of e-cigarette smokers was noticeably higher than tobacco cigarette smokers. Various research papers focusing on different communities have reported a low-to-moderate level of knowledge and awareness of e-cigarette's effects on health. E-cigarettes were initially advertised as devices to help people quit smoking, but the use of e-cigarettes in modern days has changed considerably. A big chunk of the population perceived that e-cigarettes have no harmful effects because they are nicotine-free and thus are used as a replacement for regular cigarettes rather than as a way to quit smoking. Objectives The study aimed to assess the perception of e-cigarette consumption and associated factors among the Saudi population in Jeddah city. Methodology A cross-sectional study was conducted on the Saudi population in Jeddah, Saudi Arabia, during the year 2023. The study assessed the participant's perceptions of e-cigarette consumption and its risk factors. A pre-existing online questionnaire created by Google Forms was distributed among the population through social media applications to collect data after obtaining their informed consent. Results A total of 515 participants were included in this study. Relatives and friends were the most common sources (54%) for information about e-cigarettes. Of the sample, 17.5% thought that e-cigarettes were safer than conventional cigarettes, 13.4% used e-cigarettes on a regular basis, and 65% had not smoked electronically before. Vaping pushed only 17.2% to try traditional tobacco cigarettes, and 25% stopped using traditional tobacco products after starting to smoke e-cigarettes. Gender, age group, and total family salary were the associated factors with the use of e-cigarettes. In addition, an association between the perception of e-smoking and its use was noticed, as well as a significant association between gender and withdrawal symptoms. Conclusion A minority of the participants perceived that e-cigarette smoking is safer than conventional methods of smoking. The majority did not practice e-smoking at all. Furthermore, results showed that relatives and friends were the most common sources of information. The findings from the correlation testing underscore several noteworthy associations within the studied population. Notably, gender, age, total family salary, and occupation exhibited statistically significant correlations with e-cigarette usage.

Post-thyroidectomy Depression and Associated Factors in Saudi Arabia.

Background Thyroidectomy is a common surgical procedure used to treat thyroid gland illnesses. The surgery has many outcomes, and one of them may show an association with depression. This study aims to assess the factors associated with depression after thyroidectomy in Saudi Arabia. Methodology A cross-sectional study was conducted among 414 Saudi participants. The target population included patients more than 18 years old and who had undergone thyroidectomy, whereas patients 18 years or younger were excluded. The data were collected between December 2023 and January 2024 using an electronic self-administered questionnaire that included demographics, clinical characteristics, and the nine-item Patient Health Questionnaire. The questionnaire was distributed randomly throughout social media, and patient consent was obtained. The descriptive and inferential analyses were performed using SPSS software version 27 (IBM Corp., Armonk, NY, USA). Results The study showed that of the 414 participants, 306 were females and 108 were males. Depression affected 335 (80.92%) participants and was mostly mild (120, 28.99%), followed by moderate (109, 26.33%), moderately severe (55, 13.29%), and severe (51, 12.32%). Depression symptoms were more common in females than males. The participants who underwent total thyroidectomy (217, 52.41%) were more than those who underwent partial thyroidectomy (197, 47.58%). Temporary complications were more prevalent in the participants exhibiting symptoms of depression. Both educational level and surgery time were significant factors. Conclusions The study revealed a significant prevalence of post-thyroidectomy depression. The associated factors in post-thyroidectomy depression included educational level, with more depression symptoms noted with high education. In addition, surgery time showed an increased risk of developing depression that still existed two years postoperatively.

Clinical Presentation and Treatment Patterns of Pediatric Epistaxis: A Single-Center Study.

BACKGROUND: Epistaxis, commonly known as nose bleeding, is a prevalent condition in pediatric patients, often managed either at home or in clinical settings. This study aimed to explore the differences in the management of pediatric epistaxis between home and clinical settings, focusing on gender distribution, clinical presentations, and treatment methods. METHODS: A retrospective review was conducted, analyzing pediatric epistaxis cases managed both at home and in clinical settings. Data on gender distribution, clinical presentation, and treatment methods were collected and analyzed. Home remedies, first aid management, and clinical interventions like the use of nasal sprays and septoplasty were evaluated. RESULTS: The study found significant differences in gender distribution between home (46.2% males) and clinical settings (61% males). Recurrent nasal bleeding was more common in home settings (75%), whereas more complex cases were predominant in clinical settings. Nasal sprays containing decongestants were widely used in clinical settings (62.1%), contrasting with a preference for first aid measures at home. Surgical interventions like septoplasty were occasionally employed in clinical scenarios. CONCLUSION: The study highlights distinct approaches to managing pediatric epistaxis in home versus clinical settings. It underscores the importance of tailored treatment strategies, considering the severity and frequency of epistaxis episodes. These findings suggest a need for comprehensive guidelines to assist caregivers and healthcare professionals in effective decision-making for pediatric epistaxis management. The study also emphasizes the necessity for ongoing research and education in this area.

Recent Patterns and Assessment of Long-term Complications followi ngSARS-CoV-2 Infection and Vaccination in the Context of Diabet esPrevalence among Blood Donors.

BACKGROUND: Much increasing evidence has suggested that long-term complications post vaccination of SARS-CoV-2 experience a wide range of complication including diabetes. The risk and burden of type 1 diabetes is extensively reported, but type 2 diabetes mellitus (T2D) has yet to be characterized. To address this gap, we aimed to examine trends of long-term complications post SARS-CoV-2 infection and vaccination in diabetes incidence among the Saudi population. METHODS: In this cross-sectional hospital-based study, we analyzed the blood profile of first-time blood donors from the University Hospital of King Abdulaziz University, Jeddah. Saudi Arabia. Various blood parameters, HbA1c was measured in the month of May 2023. All the donors were non-diabetic and were never diagnosed with T2D before the current blood donation. 203 healthy subjects donated their blood, out of which 104 had abnormally high HbA1c tending towards diagnosis of T2D and 99 had with blood profiles. The study followed the STROBE reporting guidelines. RESULTS: Out of 203 donors 104 (male 50(48.1%), female 54(51.9%)) were diagnosed with increased HbA1c (8.24 in males) compared to 7.61 of HbA1c in females. 35.6% were above ˃65 years, with 52.9% with O+ from the ABO blood group. Liver functions indicated significant p˂0.05, 0.04, increased amount of GGT (46.47 U/L), Alkaline phosphatase (99.93 ±64.26 uL) respectively in HbA1c elevated donors KFT represented significant p˂0.05, 0.02 elevated levels of urea (6.73 ±5.51 mmol/L), creatinine (129.97 ±195.17 umol/L) respectively along with elevated values of Lactate dehydrogenase (LDH) (263.72± 196.70 uL) and triglycerides (1.66 ±0.74mmol/L) when compared to normal value of HbA1c donors. DISCUSSION: In the present cross-sectional study, significant increase in HbA1c, trending towards increased cases of T2D post SARS-CoV-2 infection and vaccination. Males are much affected compared to females. Further maximum number of cases were from donors above the age of 65 years with altered partial LFT (GGT, Alkaline phosphatase), KFT (urea, creatinine), lipid profile (TG) and LDH in post SARS-CoV-2 and vaccination blood donors. CONCLUSION: Increase in HbA1c in 50% of donors, irrespective of gender, is an alarming figure for health authorities, with altered LFT, KFT and LDH tests and, in the near future, may increase the incidence of T2D. Large-scale population-based studies are required to prevent future incidences of T2D in young children who will be vaccinated.

Palatal Rugoscopy: A Tool for Ethnicity and Gender Identification Among Saudi and Kuwaiti Populations.

Background The establishment of human identity has always been a concern after mass disasters, and the role of odontology in forensics has greatly evolved. Nowadays, palatal rugoscopy is a widely used method in the recognition of human identity due to its uniqueness in the course, direction, length, form, position, and enduring nature against disintegration. Its easy applicability, cost-effectiveness, and prompt results can be applied to festering, scorched bodies and in the absence of missing upper limbs and fingers. This study was undertaken to evaluate palatal rugoscopy as a tool to recognize human identity and gender between two different ethnic populations. Methodology A cross-sectional comparative study was conducted in the Department of Oral Maxillofacial Surgery and Diagnostic Sciences, Riyadh Elm University, Riyadh, Saudi Arabia, to recognize ethnicity and gender among the Saudi and Kuwaiti populations. A total of 364 participants were selected from the outpatient department between September 2022 and December 2022. All 364 participants were distributed into two groups after the application of inclusion and exclusion criteria. After obtaining informed consent from all study participants, study models were prepared for final interpretation. The outlining of rugae was done with the help of a sharp graphite pencil, and the assessment of various parameters, including total number, length, direction, unification, and shape of rugae, was done. A comparison was made between the two populations. SPSS version 26.0 (IBM Corp., Armonk, NY, USA) was employed to assess variations in the mean values of both the total number and the distribution of rugae on the right and left sides across different ethnic groups and genders. Results In this study, a total of 364 participants were included. Of the total participants, 184 were Saudis and 180 were Kuwaitis, with 188 males and 176 females. A comparative evaluation of rugae among ethnic groups showed that Saudi participants had a mean number of 8.92 ± 0.660 palatal rugae, whereas in Kuwaiti participants it was 8.68 ± 0.649 (p = 0.001). When rugae length was assessed between genders among Saudi participants, it was found that the majority of participants had primary rugae with a length of more than 5 mm, and the difference was statistically significant (p = 0.002). The majority of Saudi males had forwardly positioned rugae, while the majority of Saudi females had more backwardly placed rugae. When rugae length was assessed in males and females among Kuwaiti participants, it was found that males had more primary rugae than females. This study found that the majority of Kuwaiti males had a wavy shape of rugae, while the majority of Kuwaiti females had more straight rugae. Conclusions This study concluded that among the two ethnic groups, the total number, length, direction, unification, and shape of rugae were different between genders, with significant differences in some parameters. Therefore, palatal rugoscopy might be useful as a tool to recognize gender and ethnicity and may provide better results when used as an additional tool along with other dependable forensic tools.

Novel mutation in alpha-spectrin gene in Saudi patients with hereditary spherocytosis.

Hereditary spherocytosis (HS) is the most common hereditary hemolytic disorder induced by red blood cell (RBC) membrane defect. This study was undertaken to determine mutations in genes associated with RBC membrane defect in patients with HS such as α-spectrin gene (SPTA1), ß-spectrin gene (SPTB), ankyrin gene (ANK1), band 3 anion transport gene (SLC4A1) and erythrocyte membrane protein band 4.1 gene (EPB41). Blood samples were collected from 23 unrelated patients with HS. Patients were diagnosed according to the guidelines from the British Society for Hematology. All hematological examinations for the determination of RBC abnormalities and osmotic fragility tests were conducted. Genomic DNA were extracted from peripheral blood cells and coding exons of known genes for hereditary spherocytosis were enriched using Roche/KAPA sequence capture technology and sequenced on an Illumina system via next-generation sequencing (NGS). The data showed that most of the HS patients confirmed splenomegaly and showed elevated reticulocytes and abnormal bilirubin values. NGS analysis identified the heterozygous variant c.5501G > A in the exon 39 of SPTA1 gene, resulted in a Trp1834*, which leads to a premature stop codon and subsequent mRNA degradation (nonsense- mediated decay) or truncation in α spectrin. Moreover, our data also revealed conventional mutations in genes SPTB, ANK, SLC4A1 and EBP41 in severe patients of HS. In short, this is the first report that determined a novel mutation c.5501G > A in SPTA1 gene in the Saudi population. To the best of our knowledge, this variant c.5501G > A has not been described in global literature so far. This novel mutation in SPTA1 gene is unique in the Saudi population.

Perceptions of Saudis Toward Participating in the COVID-19 Convalescent Plasma Clinical Trial.

Introduction The COVID-19 pandemic has been a major public health and economic issue worldwide. Even though vaccines have been developed to reduce the spread of the infection, treating patients remains a significant challenge. This study aims to measure the perceptions of Saudis toward participating in the COVID-19 Convalescent Plasma Clinical Trial. Method A cross-sectional study measuring the perceptions of Saudis toward participating in the COVID-19 Convalescent Plasma Clinical Trial was conducted with participants who had recovered from COVID-19. The study used an online questionnaire covering variables related to demographics, awareness, attitudes, perceptions, and plans for improvement. Results A sample of 1,051 participants participated in the questionnaire. A total of 85% had recovered from COVID-19, only 2.76% had participated in clinical trials before, and 83.44% would participate if they were advised or knew about them. The participants showed a high level of education, with 88% having obtained a degree and most used social media. The results can be biased toward the participants who get their knowledge from social media and hope to learn about things on social media. The gap in knowledge about clinical trials among the participants indicated that certain age groups could be targeted through channels where they communicate the most. Conclusion Engaging the community in clinical trials and educating others about their value by sharing experiences would help promote clinical trials and activate donations.

Social Media Effect on Personal Self-Esteem Among the Population in Saudi Arabia.

Background Self-esteem is a self-valuation; it is how people perceive their own worth and how valuable they believe they are to others. In this study, our primary objective was to explore the association between social media use and self-esteem among individuals who actively engage with social media platforms in Saudi Arabia. Method This study involved individuals aged 15 and above who are active social media users residing in Saudi Arabia. The data were collected through an anonymous online cross-sectional survey. Participants were recruited using snowball and convenience sampling method. A questionnaire was administered through Google Forms to collect data from participants. The questionnaire was structured into three sections, which included gathering social and demographic information, assessing personal usage patterns, and evaluating individual self-esteem levels using an Arabic valid version of the Rosenberg Self-Esteem Scale.  Results The survey included a total of 2,551 participants. Among them, 51.3% (n = 1,309) were female, 29% (n = 741) fell within the 21-25 age group, 95.7% (n = 2,441) were of Saudi nationality, and 51.6% (n = 1,316) were single. The social media platform most frequently used by participants was TikTok 98.5% (n = 2,512), followed by Facebook 95.7% (n = 2,441), Telegram 89.8% (n = 2,291), YouTube 72.2% (n = 1,942), WhatsApp 66.0% (n = 1,683), and finally, Snapchat 30.7% (n = 1,769). In total, 14.3% (n= 366) have low self-esteem, participants scored around 16.10 ± 1.80, ranging from 5 to 25. The following variables were significantly associated with self-esteem: female sex (83.88% vs 87.52%, X2 = 6.87, p = 0.009), nationality (X2 = 13.507, p < 0.001), marital status (X2 = 12.313, p = 0.006), region (X2 = 18.36, p = 0.001), using Tik Tok (X2 = 4.11, p = 0.043), the frequency of posting comments (X2 = 12.01, p = 0.017), comparing oneself to others (X2 = 27.94, p < 0.001), using social media because of weak personal communication (X2 = 6.56, p = 0.010), using social media to follow news (X2 = 6.89, p = 0.009), and the perceived effect of social media (X2 = 16.28, p < 0.001). Conclusions Our findings revealed that a minority of participants exhibited low self-esteem, and individuals from the Northern region were more likely to report such issues. Sociodemographic factors, including gender, nationality, and marital status, demonstrated associations with self-esteem. Additionally, the frequency of comments, TikTok usage, and peer comparison significantly influenced self-esteem levels.

Molecular patterns of alpha-thalassemia in the kingdom of Saudi Arabia: identification of prevalent genotypes and regions with high incidence.

BACKGROUND: Alpha-thalassemia (α-thalassemia) is one of the most common monogenic diseases in Saudi Arabia and is associated with significant morbidity. Premarital testing programs in Saudi Arabia reduce the burden of hemoglobinopathy disorders, and ongoing monitoring is required. We aimed to explore the molecular nature of α-globin genes and identify the most common genotypes and regions with a high risk of α-thalassemia in Saudi Arabia. METHODS: This retrospective study was conducted between January 2021 and December 2022. Six hundred twenty-five samples from patients with microcytic hypochromic anemia in Saudi Arabia were analyzed using reverse dot blot hybridization (RDBH)-based multiplex-PCR, which screens for the known 21 mutations of α-globin genes. RESULTS: Seven mutations in the α-globin gene were identified in 88.96% (556) patients. The most frequent abnormality of a-globin genes was -α3.7 (62.3%), followed by α2IVS1(-5nt) (20.7%) and α2 polyA-1 (α2T.Saudi) (14.1%). Interestingly, α2 polyA-2 (α2T.Turkish) was identified in Saudi and presented with -MED, causing Haemoglobin H disease. The incidence of α-thalassemia in Saudi Arabia's cities showed significant differences (P = 0.004). Jeddah City had the highest percentage of cases (25%), followed by Makkah (23%), Taif (13.3%), and Al-Ahassa (12.4%). CONCLUSION: The study provides current knowledge about the molecular nature of α- thalassemia, highlights the common genotypes that could contribute to disease occurrence in the Saudi population, and sheds light on Saudi regions with a high incidence. It also recommends further studies in a larger population and with differently composed molecular assays to verify these findings.

Choroidal thickness measurements in young Saudi adult population: a cross-sectional study.

AIM: To determine the choroidal thickness (CT) in young healthy Saudi adults using spectral-domain optical coherence tomography (SD-OCT) with an automated CT segmentation software. METHODS: Fifty-eight young adults (total of 116 eyes), 39 males and 19 females participated in this study between the ages of 18 and 38y (mean 22.65±3.9y). All participants underwent ophthalmic screening examination, including the SD-OCT for measurements of CT in each quadrant egmented into five eccentric regions starting from the foveal region up to 4.5 mm towards the periphery. RESULTS: The choroid was thickest in the foveal region (central 1 mm, 300±60 µm) and began to progressively thinner beyond the parafovea (1.5-2.5 mm, 284±67 µm) towards the peripheral region (3.5-4.5 mm from the fovea, 254±83 µm). The superior choroid showed the thickest profile (309±57 µm), while the nasal choroid exhibited the thinnest (229±76 µm). The rate of the thinning with increasing eccentricity was more predominant in the nasal choroid, which thinned from the foveal region (294±58 µm) to the peripheral region (158±55 µm). The superior and inferior choroid did not show a statistically significant thinning with eccentricity (all P>0.05). There was no statistically significant difference in the CT between gender, age, and laterality of the eyes (all P>0.05). A significant association of myopia with thinner subfoveal choroid was observed (Pearson's, r=0.37), and regression analysis showed that a 10.3 µm choroidal thinning for each diopter increase of myopia. CONCLUSION: CT profile depends on eccentric and the quadrant. The CT profile across the measured area in the young Saudi adult population is comparable to other previous reports. Refractive error is critical for CT evaluation.

Molecular Effect of Variants in Toll-like Receptor 4 Gene in Saudi Patients with Type 2 Diabetes Mellitus.

Single-nucleotide polymorphisms (SNPs) in the Toll-like receptor 4 (TLR4) gene have been documented in type 2 diabetes mellitus (T2DM) and other diseases in the Saudi population. We investigated the relationship between rs11536889, rs4986790, and rs4986791 SNPs in the TLR4 gene and T2DM in the Saudi population; 105 patients with T2DM and 105 healthy controls were analyzed. The TLR4 gene was amplified through PCR, followed by restriction fragment length polymorphism analysis for rs4986791 and Sanger sequencing for rs11536889 and rs4986790 SNPs. The clinical and biochemical characteristics were associated with T2DM (p < 0.05). The rs11536889, rs4986790, and rs4986791 SNPs in control subjects followed the Hardy-Weinberg equilibrium (p > 0.05). Alleles were associated with rs11536889, rs4986791, heterozygous codominant, and dominant models (p < 0.05). However, the rs4986790 SNP was not associated with T2DM (p > 0.05). Logistic regression analysis showed that high-density lipoprotein cholesterol (HDLc) levels were associated with T2DM (p < 0.001). Analysis of variance showed that waist (p = 0.0005) and hip circumferences (p = 0.002) in rs4986790 and rs4986791 SNPs, in SBP (p = 0.001), DBP (p = 0.002), and HDLc levels (p = 0.003), were associated with T2DM subjects. T2DM was also associated with the haplotype (p < 0.001) but not with linkage disequilibrium. The gene-gene interaction was associated with the three SNPs studied in patients with T2DM according to the generalized multifactor dimensionality reduction model (p < 0.0001). Dendrogram and graphical depletion analysis revealed a moderate association in patients with T2DM. The results suggest that rs11536889 and rs4986790 SNPs are genotypically and allelically associated with T2DM in Saudi patients. Future functional studies are recommended to validate the genetic roles of these SNPs in the pathogenesis and progression of diseases.

Assessment of calcium intake and recognition of calcium-rich food sources among the Saudi population.

Calcium is an essential skeletal mineral, and calcium deficiency has a negative impact on bone health. We conducted an online questionnaire to assess the intake and knowledge among the Saudi population. The survey included 950 participants, with 51.1% demonstrating poor knowledge of calcium sources and a mean intake lower than the recommended level. INTRODUCTION: Calcium is an essential mineral and one of the most prevalent in the body. Chronic insufficient calcium intake increases the risk of osteopenia, osteoporosis, and bone fracture. PURPOSE: This study aimed to assess the Saudi population's calcium intake and knowledge of calcium sources as well as to identify factors associated with inadequate calcium intake. METHODS: This cross-sectional study was conducted across Saudi Arabia using an online questionnaire distributed randomly through social media channels. The questionnaire was a validated tool that was previously developed and used by the original author to assess knowledge of calcium food sources and estimate calcium intake in the Saudi population. If an individual answered more than 11 questions correctly, calcium knowledge was considered adequate. Calcium intake was considered sufficient or insufficient based on the recommended dietary allowance (RDA) of 1000 mg/day. RESULTS: The survey included male and female Saudi citizens and residents aged 14 years or older. A total of 950 respondents aged 9-70 completed the questionnaire. A total of 62.9% of the respondents were 26-50 years old. Of the participants, 64.2% were female, 71.7% were married, and 61.9% had a diploma or a bachelor's degree. Of these, 63.8% were from the central region, and 97.6% were from Saudi Arabia. For those aged 9-18, the average calcium consumption was 577 mg/day, whereas it was 479 mg/day for those aged 19-50. The average intake was 479 mg/day for males aged 51-70 (EAR = 1000 mg/day) and 438 mg/day for females (EAR = 1200 mg/day). These calcium consumption values were significantly lower than the estimated average requirement (EAR) and RDA (p < 0.01). Correct response rates for the 19 calcium intake knowledge items ranged from 23.4 to 94.7%. Among the participants, 48.9% had significant calcium intake knowledge, as indicated by a score of > 11 out of 19 correct responses. Age, sex, marital status, educational attainment, and residence were significantly correlated with adequate knowledge of calcium. Demographic characteristics such as age, marital status, and residence were associated with sufficient calcium intake in the study. CONCLUSION: The study findings revealed that a significant proportion (51.1%) of participants demonstrated inadequate knowledge regarding calcium food sources. Additionally, the mean calcium intake was found to be lower than the RDA of 1300 mg/day for males and females 14-18 years old and 1000 mg/day for males and females 19-50 years old and males 51-70 years old; however, the RDA for females 51-70 years old is 1200 mg/day, suggesting an urgent need for interventions aimed at enhancing both calcium knowledge and intake.

Public Knowledge and Perception of Anesthesia, Anesthesiologists' Expertise, and Their Role Among Saudi Citizens Residing in Saudi Arabia.

BACKGROUND: Despite improvements in anesthesia practice, there is still a lack of public awareness of the field, the range of an anesthesiologist's duties, and the crucial role they play in the healthcare delivery system. Thus, this study aimed to assess Saudi citizens' perceptions of anesthesiologists' training, expertise, role, and responsibilities, as well as their knowledge and concerns about anesthesia. METHOD: A cross-sectional study was conducted between December 2022 and April 2023, with a 42-question survey administered to 406 adult Saudi citizens of both genders residing in Saudi Arabia, excluding healthcare students and employees. RESULTS: Most participants were female (82.8%), aged over 40 (67.6%), held a bachelor's degree (74.6%), and reported very good health (38.7%). A majority (67.2%) had at least undergone one or more surgeries. Knowledge scores averaged 8.14 ± 2.35/14, distributed as 20% poor, 67.7% moderate, and 12.3% good. Perception scores averaged 3.25 ± 1.59/7, with 55.2% poor, 38.2% moderate, and 6.7% good. A significant positive correlation between perception and knowledge scores was found. Higher perception scores were associated with having a chronic medical condition, while higher knowledge scores were associated with being female and having undergone more surgeries. Anesthesiologists were recognized as specially trained doctors by 79.8% of participants, and 63.8% trusted physicians for care. However, 22.4% refused care. Notably, the most common anesthesia concern was fear of dying during anesthesia (very concerned: 26.6%). CONCLUSION: This study reveals knowledge gaps and misconceptions about an anesthesiologist's role and responsibilities, highlighting the need for public education to address concerns, improve patient satisfaction, and inform future research.

The Genomic Landscape of Colorectal Cancer in the Saudi Arabian Population Using a Comprehensive Genomic Panel.

PURPOSE: Next-generation sequencing (NGS) technology detects specific mutations that can provide treatment opportunities for colorectal cancer (CRC) patients. PATIENTS AND METHODS: We analyzed the mutation frequencies of common actionable genes and their association with clinicopathological characteristics and oncologic outcomes using targeted NGS in 107 Saudi Arabian patients without a family history of CRC. RESULTS: Approximately 98% of patients had genetic alterations. Frequent mutations were observed in BRCA2 (79%), CHEK1 (78%), ATM (76%), PMS2 (76%), ATR (74%), and MYCL (73%). The APC gene was not included in the panel. Statistical analysis using the Cox proportional hazards model revealed an unusual positive association between poorly differentiated tumors and survival rates (p = 0.025). Although no significant univariate associations between specific mutations or overall mutation rate and overall survival were found, our preliminary analysis of the molecular markers for CRC in a predominantly Arab population can provide insights into the molecular pathways that play a significant role in the underlying disease progression. CONCLUSIONS: These results may help optimize personalized therapy when drugs specific to a patient's mutation profile have already been developed.

Development of a Cardiovascular Disease Risk Prediction Model: A Preliminary Retrospective Cohort Study of a Patient Sample in Saudi Arabia.

Saudi Arabia has an alarmingly high incidence of cardiovascular disease (CVD) and its associated risk factors. To effectively assess CVD risk, it is essential to develop tailored models for diverse regions and ethnicities using local population variables. No CVD risk prediction model has been locally developed. This study aims to develop the first 10-year CVD risk prediction model for Saudi adults aged 18 to 75 years. The electronic health records of Saudi male and female patients aged 18 to 75 years, who were seen in primary care settings between 2002 and 2019, were reviewed retrospectively via the Integrated Clinical Information System (ICIS) database (from January 2002 to February 2019). The Cox regression model was used to identify the risk factors and develop the CVD risk prediction model. Overall, 451 patients were included in this study, with a mean follow-up of 12.05 years. Thirty-five (7.7%) patients developed a CVD event. The following risk factors were included: fasting blood sugar (FBS) and high-density lipoprotein cholesterol (HDL-c), heart failure, antihyperlipidemic therapy, antithrombotic therapy, and antihypertension therapy. The Bayesian information criterion (BIC) score was 314.4. This is the first prediction model developed in Saudi Arabia and the second in any Arab country after the Omani study. We assume that our CVD predication model will have the potential to be used widely after the validation study.
