RESUMEN
Introduction In the modern era, technology, including artificial intelligence (AI), is the centre of digital innovation. AI is revolutionising numerous fields, including the healthcare sector, globally. Incorporating AI in dental education may help in improving the diagnostic accuracy, learners' experiences, and effectiveness of the management of dental education institutions. However, successful implementation of AI requires the faculty's willingness to incorporate it into their practices. Thus, this research aims to explore the readiness of faculty members to integrate AI into dental education. Methodology The study employed a qualitative exploratory design to gather in-depth insights into faculty readiness for AI-driven dental education. Purposive sampling was employed, and 21 faculty members from public and private dental colleges in South Punjab participated in semi-structured interviews. The interviews focused on understanding participants' perceptions, experiences, and challenges related to AI integration in dental education. Thematic analysis was conducted utilising Braun and Clarke's framework to identify key themes and subthemes from the qualitative data using inductive coding. Results Five major themes and 14 subthemes emerged from the data analysis. Faculty members had low AI literacy coupled with diverse perceptions; some participants perceived AI as a solution for revolutionising teaching and learning, while others criticised its misuse as academic misconduct by students, an effect on students' critical thinking, and a threat to conventional jobs. However, most of the respondents also considered AI beneficial for students with remote access or from marginalised populations in terms of accessing and learning from limited resources. Concerns that participants highlighted included a lack of training opportunities, limited facilities, ethical concerns pertaining to data privacy, and assessment bias. Some of the recommendations provided by the respondents include the provision of training opportunities, the allocation of resources and infrastructure, and continuous effective support from institutions for the integration of AI in dental education. Conclusions This study emphasised the readiness of the faculty when it comes to the integration of AI in dental education. The faculty considered AI favourable for digitization and innovative education, although there is a lack of awareness of its application. Regarding the benefits of utilising AI, respondents highlighted its quick response, prediction of students' performance, and flexibility in learning. The challenges included lack of awareness regarding its implementation, inadequate training, lack of availability of resources, lack of institutional support, the problem of data confidentiality, and resistance to change. Suggestions included the provision of technical support, skills training, and the provision of required infrastructure. Participants recommended that AI tools must incorporate cultural and contextually specific content, use technical support for problems, and incorporate constant response systems to improve the AI tools for novice users, especially within developing regions such as Pakistan.
RESUMEN
Morgagni hernia (MH) is a rare form of congenital diaphragmatic hernia, typically occurring predominantly on the right side and exhibiting a higher prevalence in females. Usually diagnosed incidentally, MH may coexist with congenital heart defects, chest wall abnormalities and certain genetic syndromes such as Down syndrome. A 4-year-old boy with Down syndrome underwent simultaneous repair of MH and closure of a ventricular septal defect (VSD). A vertical midline sternotomy was performed, and the VSD was repaired using the right atrium approach. Subsequently, MH repair was conducted. Three weeks after the surgery, this patient developed a complete heart block, which lead to the implantation of a VVI pacemaker.
RESUMEN
Purpose: The purpose of study was to investigate dental anxiety (DA) and its relationship with oral health problems, dental visits, and socio-demographic factors among physicians. Patients and Methods: This cross-sectional study was conducted on physicians working in Dhahran, Khobar, Dammam, and Qatif cities of the kingdom of Saudi Arabia. The study included physicians (general practitioners, residents, specialists, and consultants) working in the public and private sectors. Modified Dental Anxiety Scale and World Health Organization's Oral Health Questionnaire for Adults were used to evaluate DA, oral health problems, and dental attendance. Results: The study included data from 355 participants with a mean age of 40.13 ± 10.45 years. There were 57.2% of non-Saudi and 42.8% of Saudi participants in the study. Bad dental experience in the previous dental visit was reported by 40% of participants, which was significantly related to DA (P = 0.002). Only 9.60% of participants had no DA, whereas 41.10% demonstrated low DA, 23.4% moderate DA, 18.9% high DA, and 7% extreme DA. Common oral problems included tooth sensitivity (65.40%), tooth cavities (45.90%), bleeding gums (43.10%), and bad breath (36.90%). More than half of participants (58.3%) visited the dentist during the last year and dental pain was the most common reason for dental visits (31.3%). Saudi participants demonstrated significantly increased DA than non-Saudis (P = 0.019). DA was significantly related to tooth sensitivity (P = 0.001), tooth cavities (P = 0.002), dry mouth (P = 0.044), and bad breath (P = 0.005). The participants with difficulty in biting foods (P > 0.001) and feeling embarrassed due to the appearance of teeth (P < 0.001) demonstrated significantly higher DA. Conclusion: This sample of physicians showed a high prevalence of DA, oral problems, and dental visits due to pain. DA was significantly related to physicians' negative dental experience, tooth sensitivity, dental decay, dry mouth, and bad breath.
RESUMEN
Background: Limited studies from Saudi Arabia have assessed the quality of life (QoL) of end-stage kidney disease (ESKD) patients on hemodialysis and its associated factors. Objective: To determine the physical, psychological, familial, and social factors that impact the QoL of ESKD patients in Saudi Arabia. Materials and Methods: This cross-sectional study included adult patients with ESKD who underwent hemodialysis at King Salman Center for Kidney Disease and King Fahad Medical City, Riyadh, Saudi Arabia, between June and July 2021, and had been on dialysis for ≥1 year were included. The Arabic version of the Quality of Life Index-Dialysis (QLI-D) version III was used, which has four sub-scales. Results: A total of 173 respondents completed the questionnaire. The overall mean (±SD) QoL score was 22.2 (±4.30), while the scores for the sub-scales ranged from 20.8 (±5.25) (Health and Functioning subscale) to 26.0 (Family subscale). Respondents aged >70 years had significantly lower average score (P < 0.05) and lower Health and Functioning subscale score (P < 0.05). Education and higher income had significant positive correlation with the Social and Economic subscale (r = 0.234, P < 0.01; and r = 0.162, P < 0.05, respectively). Diabetes was significantly associated with lower scores in the Health and Functioning subscale (P < 0.05). There was a positive linear trend in the association between the number of years on dialysis and the overall QLI-D score and the subscales of QLI-D (P < 0.05). Conclusion: Higher education level and income and longer duration of dialysis were factors associated with better QoL, while older age and having diabetes were associated with poorer QoL. Awareness among healthcare providers regarding these factors can help improve the QoL of these patients.
RESUMEN
AIM: Inflammatory-regenerative cell interaction is believed to mediate hard tissue formation. This study aimed to investigate the interaction between human inflammatory monocytes with human regenerative fibroblasts after exposure to different calcium silicate materials. METHODOLOGY: Human monocytes were cultured on three materials, polystyrene (PS), mineral trioxide aggregates (MTA) and biodentine (BD), in the presence or absence of lipopolysaccharide (LPS). Half of the monocyte-conditioned media (MoCM) of each group was used to analyse inflammatory cytokine secretion, namely TNF-α, IL-1ß, IL-1RA and IL-6. The remaining MoCM was used to culture recipient fibroblasts, measuring the cell number (proliferation) and levels of alkaline phosphatase (differentiation) and lactic acid dehydrogenase (cytotoxicity). RESULTS: In absence of LPS, MTA was associated with higher secretion of TNF-α and lower secretion of IL-1ß, while BD triggered higher secretions of both cytokines when both materials were compared to control (PS). When LPS was added, higher levels of all analysed cytokines were observed in the PS and BD groups, whereas for the MTA group, only TNF-α and IL-6 were increased. Fibroblasts responded differently to the MoCM from the different groups, revealing significant increases in proliferation and differentiation capacities, particularly when cultured in CM from monocytes exposed to MTA. The morphological evaluation revealed different patterns of fibroblast shape and spread in the different MoCM groups. CONCLUSION: Calcium silicate materials modulate the monocyte inflammatory response, which subsequently induce differential effects on the recipient fibroblasts. MTA appears to promote the secretion of prodifferentiation signals from the monocytes, which are received by fibroblasts, promoting their proliferation and differentiation. The model represents a promising tool to evaluate the interaction of different cells in response to different materials.

OBJECTIVE: Twitter as a social media platform has revolutionized the way we interact with others and receive information. The presence of dental schools in Twitter facilitates the engagement of students, educators, dental professionals, and the community. Given the explosive popularity of Twitter as a social media platform and its potential use in the areas of education and branding, the questions of why and how dental schools use these services warrant comprehensive research. Thus, the aim of this study was to analyze the pattern and use of Twitter as a social media platform for dental schools in Saudi Arabia. METHODS: The tweets were extracted within the timeframe from July 15, 2019, to July 15, 2020. The Twitter data collected included: full text content, the count of retweets, quotes, replies and likes. Extracted tweets were categorized into five main themes: news and announcement, dental professional communication, general communication, oral health education, and promoting participation. Tweets in each main theme were further categorized according to the dental schools' academic roles namely; education, research and community service. In addition, tweets were classified according to originality of the tweet, language used, nature of the tweet and the use of hashtags and mentions. Descriptive analysis presented in the form of frequency tables with percentages and mean (SD) as well as graphical presentation of the pattern and use of Twitter for Saudi dental schools in the form of bar, pie and line charts. Categorical data were analyzed using chi square test, while continuous data were analyzed using ANOVA. Statistical significance was set at p ≤ 0.05. RESULTS: A total of 15 Saudi dental schools with Twitter accounts were included in the analysis. King Saud University (KSU) had the largest number of followers with 17,200. Within the time frame of this study, a total of 1,889 original tweets from dental schools were found. Imam Abdulrahman Bin Faisal University (IAU) had the highest number of posted tweets (n = 647, 34.3%). The distribution of tweets was highest in September 2019 (n = 239) and lowest in July 2020 (n = 22). Majority of the tweets (81.9%) belonged to five out of the 15 dental schools. News and announcements were the most tweeted thematic subject with 1,034 tweets (55%). While community service was the most tweeted academic role with 803 tweets (42%). The top five active dental schools' performance for both thematic and academic role classifications were significantly different based on the chi square test (p < 0.001). CONCLUSION: This study highlights the importance of Twitter as a social media platform, in dental education especially when it comes to presence and branding for dental schools. Twitter is a helpful platform to expose dental schools to the community, this can be seen by their academic achievements as well as their active role with community service.

This study aimed to assess the association of obesity with the severity and outcome of COVID-19 infection. A retrospective observational study was performed from March to September 2020 in Saudi Arabia. Baseline and laboratory data were collected from the inpatient health record system. The cohort was divided into three groups based on body mass index. Following this, the severity and outcome of COVID-19 disease were analyzed between the three groups. Of the 502 COVID-19 cases included, 244 (48.5%) were obese. Obesity was significantly associated with severe (53.5%) or critical (28%) COVID-19 infection (P<0.001) and a higher need for ICU admission (35.8%, P=0.034). Multivariate analysis showed that overweight/obesity was an independent risk factor of severe (P<0.001) as well as critical COVID-19 infection (P=0.026, respectively) and a predictor of a higher risk of ICU admission (P=0.012). Class I obesity was associated with severe-critical COVID-19 disease (33.6%, P=0.042) compared to other obesity classes. Obesity is an independent risk factor for severe-critical COVID-19 infection and a higher risk of ICU admission. Clinicians should give special attention to such populations and prioritize vaccination programs to improve outcomes.

Rett syndrome is a neurodevelopmental genetic X-linked disorder. It is predominantly found in females with a prevalence rate of 1 : 9000. Rett syndrome patients are usually healthy the first months of their lives. The syndrome goes into a deceleration phase where motor, behavioral, and cognitive skills are impaired. Regarding their oral health, bruxism is one of the common oral manifestations found among Rett syndrome patients. We present a case of an 8-year-old patient with Rett syndrome who presented to the dental clinic for oral rehabilitation. The patient was evaluated and treated under general anesthesia with multiple extractions, restorations, and crown installments. Oral rehabilitation of Rett syndrome is important for those patients, and proper evaluation and treatment are the most efficient when performed under general anesthesia.
RESUMEN
Background: This study was designed to investigate Saudis' attitudes toward mental distress and psychotropic medication, attribution of causes, expected side effects, and to analyze participants' expectations toward alternative or complementary medicine using aromatic and medicinal plants, through a survey. Method: The study included 674 participants (citizens and residents in Saudi Arabia) who were randomly contacted via email and social media and gave their consent to complete a questionnaire dealing with 39 items that can be clustered in six parts. Descriptive statistics and Chi-square for cross-tabulation were generated using SPSS. Results: Among the 664 participants, 73.4% believed that there are some positive and negative outcomes of psychotropic medication. Participants (72.0%) think that the most important reason leading to psychological disorders is mainly due to the loss of a relative or beloved person, and 73.9% considered psychic session as one of the possible treatments of psychological disorders. Surprisingly, only 18.8% of the participants agreed that medicinal and aromatic plants could be a possible treatment of the psychological disorder. Participants (82%) consider that physicians are the most trustful and preferred source of information about alternative and complementary medicine.
RESUMEN
Bacteria belonging to the genus Aneurinibacillus within the family Paenibacillaceae are Gram-positive, endospore-forming, and rod-shaped bacteria inhabiting diverse environments. Currently, there are eight validly described species of Aneurinibacillus; however, several unclassified species have also been reported. Aneurinibacillus spp. have shown the potential for producing secondary metabolites (SMs) and demonstrated diverse types of enzyme activities. These features make them promising candidates with industrial implications. At present, genomes of 9 unique species from the genus Aneurinibacillus are available, which can be utilized to decipher invaluable information on their biosynthetic potential as well as enzyme activities. In this work, we performed the comparative genome analyses of nine Aneurinibacillus species representing the first such comprehensive study of this genus at the genome level. We focused on discovering the biosynthetic, biodegradation, and heavy metal resistance potential of this under-investigated genus. The results indicate that the genomes of Aneurinibacillus contain SM-producing regions with diverse bioactivities, including antimicrobial and antiviral activities. Several carbohydrate-active enzymes (CAZymes) and genes involved in heavy metal resistance were also identified. Additionally, a broad range of enzyme classes were also identified in the Aneurinibacillus pan-genomes, making this group of bacteria potential candidates for future investigations with industrial applications.
RESUMEN
Nanoparticles form the fundamental building blocks for many exciting applications in various scientific disciplines due to its unique features such as large surface to mass ratio, targeting potential, ability to adsorbed and carry other compound which makes them suitable for biomedical applications. However, the problem of the large-scale synthesis of nanoparticles remains challenging due to physical instability associated with nanoparticles which lead to generation of aggregates particles with high polydispersity index (PDI) indicating low particle homogeneity and eventually loss of their special nanoscale properties. The stabilisation concept can be generated by repulsive electrostatic force, which nanoparticles experience, when they are surrounded by a double layer of electric charges. Selection of proper stabiliser will govern the stability of NPs and ultimately development of optimised drug delivery system. This review summarises mechanism of physical instability issues likely to be encountered during the development of nanoformulations. It also discusses potential stabilising agents used so far and their mechanism in achieving stable nanosystems.

Substance abuse is a chronic, relapsing disorder characterized by compulsive drug use regardless of negative consequences. Incremental increases in pregabalin abuse have been observed in Saudi Arabia and throughout the world. In previous studies, the potential for pregabalin abuse with escalating doses of the drug (30, 60, 90, and 120 mg/kg) were investigated in male mice. Notably, researchers have argued that women may exhibit a greater tendency to consume drugs without a prescription to alleviate stress and depression. Moreover, female subjects are more prone to impulsivity in drug intake or abuse than their male counterparts. Therefore, in the present study, we compared the potential for pregabalin abuse between male and female mice using a conditioned place preference paradigm. Male and female BALB/c mice were divided into four groups based on the pregabalin dose administered (30, 60, 90, or 120 mg/kg, intraperitoneal). Preference scores were then calculated and compared between male and female mice in each dosage group. Interestingly, preference scores were significantly higher in female mice than in male mice at dosages of 30 and 120 mg/kg. These findings indicate that female mice may be more prone to pregabalin abuse and tolerance than male mice. These results might be helpful to the healthcare providers and policymakers to consider these sex differences in choosing therapeutic plans and consider alternatives to the misused prescription medications.
RESUMEN
The adult intestine hosts a huge number of diverse bacterial species, collectively referred to as the microbiome, that reside mainly in the lower gut, where they maintain a symbiotic relationship with their host. Recent research points to a central role of the microbiome in many biological processes. These microbial communities are influenced by multiple environmental and dietary factors and can modulate immune responses. In addition to local effects on the gastrointestinal tract, the microbiota is associated with effects on other organs and tissues, such as the skin. Indeed, an altered microbiome has been associated with skin disorders in several instances. Thus, in this review, we describe the recent advances regarding the interplay between gut microbiota and the skin. We explore how this potential link affects skin homeostasis and its influence on modulating the cutaneous immune response, focusing on psoriasis disorder. Finally, we discuss how to take advantage of this interplay to manage this disorder, particularly through probiotics administration. In the gastrointestinal tract, the microbiome has been proven to be important in the maintenance of the balance between effector T cells and regulatory T cells, and the induction of immunoglobulin A. Moreover, gut bacterial dysbiosis is associated with chronic inflammatory disorders of the skin, such as psoriasis. Thus, the microbiome can be considered an effective therapeutical target for treating this disorder. Despite some limitations, interventions with probiotics seem promising for the development of a preventive therapy by restoring altered microbiome functionality or as an adjuvant in specific immunotherapy.
RESUMEN
BACKGROUND: Cardiovascular disease (CVD) is the primary cause of death worldwide, accounting for 31.0% of all deaths and more than 18 million deaths annually. The 2008 World Health Report indicated that 144 (35%) of the 413 deaths per 100,000 in 2002 in the Kingdom of Saudi Arabia (KSA) were due to CVD. Primary prevention is an important focus of most of the cardiovascular prevention guidelines around the world. In this study, we aimed to describe the prevalence of extrinsic risk factors for CVDs in a high-risk population attending general practice in Jeddah, KSA. METHODS: We conducted a cross-sectional survey at King Abdulaziz University Hospital in Jeddah. Patients started on lipid-lowering and/or antihypertensive and/or antidiabetes treatments without a history of established cardiovascular disease were interviewed. The questionnaire was adopted from the EUROASPIRE III study. RESULTS: Two hundred and fifty high-risk individuals (80.0% female) were interviewed. Overall, 72% of the patients had been diagnosed with hypertension, 61.2% of patients had dyslipidemia, and approximately two-thirds of patients had diabetes mellitus. Most of the patients (88%) were non-smokers. The mean waist circumference of patients was 101.6 ± 14.1 cm, which suggests most were clinically obese. About 54.8% of the patients followed an unhealthy diet and 52.0% were physically inactive. There were significant differences between women and men in relation to dyslipidemia (p = 0.007), unhealthy diet (p = 0.034), being overweight (p = 0.018), and high blood cholesterol (p = 0.002). We observed significantly greater prevalence of hypertension (p = 0.073), unhealthy diet (p = 0.015), being overweight (p = 0.018), and high blood cholesterol (p = 0.000) in those patients with dyslipidemia. CONCLUSION: Our study presents novel findings in the KSA. Women were more likely to have high-risk CVD risk factors compared with their male counterparts in this sample. Gender-specific prevention programs in the KSA should be considered to more appropriately target at-risk individuals, to reduce preventable morbidity and mortality associated with CVDs.

Coronary heart disease is a serious complication of dyslipidemia. Pitavastatin is a more commonly prescribed medication for the treatment of dyslipidemia. Here, we report the case of a 37-year-old female, a known patient with well-controlled bronchial asthma. She was recently found to be dyslipidemic and started on pitavastatin calcium 4 mg once a day (OD). On the 10th day of treatment, she began to have crushing chest pain and was admitted to the hospital. All investigations for coronary heart disease came out negative. Her symptoms improved dramatically when pitavastatin was stopped. Pitavastatin is reported to cause myalgia and muscle spasm, especially at higher doses. There is evidence in literature that this medication might cause chest pain in old obese ladies if taken at high doses. We report this case as a possibility of chest pain even in younger females.
RESUMEN
Gestational diabetes mellitus (GDM) is a glucose intolerance disorder which occurs during pregnancy as a result of insulin insensitivity; it usually disappears after delivery. However, some women with GDM can develop type 2 diabetes (T2D) after delivery, and the mechanisms by which this occurs remain unknown. This study compared the levels of sirtuins (NAD-dependent deacetylases) and antioxidative enzymes in postpartum women with previous GDM (pGDM) or T2D and in postpartum women with a previous healthy pregnancy (controls). Women with pGDM showed upregulated levels of sirtuin 1 (SIRT1) mRNA and protein, with reduced expression levels of sirtuin 3 (SIRT3) and superoxide dismutase 2 (SOD2), relative to the controls. Women with T2D similarly showed a lower level of SIRT3 mRNA than the controls. Lipid peroxidation (malondialdehyde) was higher in women with pGDM than in the controls. These data show that in women with pGDM, the reduced level of SIRT3 may play a role in the reduced SOD2 level, possibly leading to oxidative stress, which, in turn, upregulates the level of SIRT1. These results might confer the risk of future diabetes development in women with pGDM, as a similar reduction in SIRT3 was found in women with T2D.
RESUMEN
Most data on differentiated thyroid cancer (DTC) came from the Western world. We describe its salient characteristics and outcome from a Middle Eastern country. Patients and Methods. We studied all cases of TC seen during a 2-year period (2004-2005) seen at our institution. Results. A total of 600 consecutive cases of DTC with a median age at diagnosis of 39 years (5-85) and the female : male ratio of 459 : 141 (76.5% : 23.5%). The cases included classical papillary thyroid cancer (PTC) in 77%, follicular variant PTC in 13.3%, follicular thyroid cancer in 3.2%, and other rare subtypes 6.5%. Total or near-total thyroidectomy was performed in 93%, central and/or lateral neck dissection in 64.5% of cases, and radioactive iodine ablation in 82% of cases. Additional therapies were administered to 154 patients (25.7%). At a median follow-up period of 7.63 years (0.22-13.1), 318 patients (53.3%) were in excellent response, 147 (24.5%) having an indeterminate response, 55 (9.2%) biochemically incomplete, 33 (5.5%) structurally incomplete, and 27 (4.5%) unclassifiable. Twenty cases died secondary to DTC (disease-specific mortality 3.3%). Conclusions. In Saudi Arabia, DTC is common and occurs at young age and predominantly in females. Although remission is common, persistent disease is also common but disease-specific mortality is low.
