RESUMO

Purpose: This study aims to assess the effectiveness of ChatGPT in remote learning among medical students. Methods: This cross-sectional survey study recruited 386 medical students from three public universities in Saudi Arabia. Participants completed an online questionnaire designed to assess perceptions of ChatGPT's effectiveness in remote learning. The questionnaire included Likert scale questions to evaluate various aspects of ChatGPT's support in remote learning, such as personalized learning, language and communication skills, and interactive quizzing. Data were analyzed using SPSS, employing descriptive statistics, independent samples t-tests, one-way ANOVA, and Cronbach's alpha to evaluate reliability. Results: Participants mostly used ChatGPT on a weekly (43.2%) or daily (48.7%) basis, primarily on personal computers (62.5%). Mean scores for ChatGPT's support in remote learning were high for personalized learning (4.35), language and communication skills (4.23), and interactive quizzing and assessments (4.01). Statistically significant differences were found based on gender for interactive quizzing (p = .0177) and continuity of education (p = .0122). Conclusion: Despite certain challenges and variations in perceptions based on gender and education level, the overwhelmingly positive attitudes toward ChatGPT highlight its potential as a valuable tool in medical education.

RESUMO

STUDY PURPOSE: This study aims to assess the effectiveness of ChatGPT in critical thinking skills among medical students. METHODS: This cross-sectional survey study recruited 392 medical students from three public universities in Saudi Arabia. Participants completed an online questionnaire assessing perceptions of ChatGPT's impact on critical thinking skills. Data were analyzed using SPSS, employing descriptive statistics, t-tests, analysis of variance, and Cronbach's alpha to evaluate reliability. RESULTS: Significant gender-based differences were found in perceptions of ChatGPT's efficacy, particularly in generating diverse perspectives (P = 0.0407*) and encouraging questioning (P = 0.0277*). Reflective practice perceptions varied significantly by age (P = 0.0302*), while academic backgrounds yielded significant differences across all factors assessed (P < 0.0001*). Overall, 92.6% believed integrating ChatGPT would benefit critical thinking skills. Most participants (N = 174) strongly agreed that ChatGPT improved critical thinking. CONCLUSION: Integrating ChatGPT into medical education could offer valuable opportunities for fostering critical thinking abilities, albeit with the need for addressing associated challenges and ensuring inclusivity.

RESUMO

BACKGROUND: Large-scale gut microbiome sequencing has revealed key links between microbiome dysfunction and metabolic diseases such as type 2 diabetes (T2D). To date, these efforts have largely focused on Western populations, with few studies assessing T2D microbiota associations in Middle Eastern communities where T2D prevalence is now over 20%. We analyzed the composition of stool 16S rRNA from 461 T2D and 119 non-T2D participants from the Eastern Province of Saudi Arabia. We quantified the abundance of microbial communities to examine any significant differences between subpopulations of samples based on diabetes status and glucose level. RESULTS: In this study we performed the largest microbiome study ever conducted in Saudi Arabia, as well as the first-ever characterization of gut microbiota T2D versus non-T2D in this population. We observed overall positive enrichment within diabetics compared to healthy individuals and amongst diabetic participants; those with high glucose levels exhibited slightly more positive enrichment compared to those at lower risk of fasting hyperglycemia. In particular, the genus Firmicutes was upregulated in diabetic individuals compared to non-diabetic individuals, and T2D was associated with an elevated Firmicutes/Bacteroidetes ratio, consistent with previous findings. CONCLUSION: Based on diabetes status and glucose levels of Saudi participants, relatively stable differences in stool composition were perceived by differential abundance and alpha diversity measures. However, community level differences are evident in the Saudi population between T2D and non-T2D individuals, and diversity patterns appear to vary from well-characterized microbiota from Western cohorts. Comparing overlapping and varying patterns in gut microbiota with other studies is critical to assessing novel treatment options in light of a rapidly growing T2D health epidemic in the region. As a rapidly emerging chronic condition in Saudi Arabia and the Middle East, T2D burdens have grown more quickly and affect larger proportions of the population than any other global region, making a regional reference T2D-microbiome dataset critical to understanding the nuances of disease development on a global scale.

RESUMO

A tumor is an abnormal tissue classified as either benign or malignant. A breast tumor is one of the most common tumors in women. Radiologists use mammograms to identify a breast tumor and classify it, which is a time-consuming process and prone to error due to the complexity of the tumor. In this study, we applied machine learning-based techniques to assist the radiologist in reading mammogram images and classifying the tumor in a very reasonable time interval. We extracted several features from the region of interest in the mammogram, which the radiologist manually annotated. These features are incorporated into a classification engine to train and build the proposed structure classification models. We used a dataset that was not previously seen in the model to evaluate the accuracy of the proposed system following the standard model evaluation schemes. Accordingly, this study found that various factors could affect the performance, which we avoided after experimenting all the possible ways. This study finally recommends using the optimized Support Vector Machine or Naïve Bayes, which produced 100% accuracy after integrating the feature selection and hyper-parameter optimization schemes.

RESUMO

Purpose: Autosomal dominant polycystic kidney disease (ADPKD) is characterized by progressive development of kidney cysts and enlargement and dysfunction of the kidneys. The Consortium of Radiologic Imaging Studies of the Polycystic Kidney Disease (CRISP) cohort revealed that 89.1% had either a PKD1 or PKD2 mutation. Of the CRISP patients with a genetic cause detected, mutations in PKD1 accounted for 85%, while mutations in the PKD2 accounted for the remaining 15%. Here, we report exome sequencing of 16 Saudi patients diagnosed with ADPKD and 16 ethnically matched controls. Methods: Exome sequencing was performed using combinatorial probe-anchor synthesis and improved DNA Nanoballs technology on BGISEQ-500 sequencers (BGI, China) using the BGI Exome V4 (59 Mb) Kit. Identified variants were validated with Sanger sequencing. Results: With the exception of GC-rich exon 1, we obtained excellent coverage of PKD1 (mean read depth = 88) including both duplicated and non-duplicated regions. Of nine patients with typical ADPKD presentations (bilateral symmetrical kidney involvement, positive family history, concordant imaging, and kidney function), four had protein truncating PKD1 mutations, one had a PKD1 missense mutation, and one had a PKD2 mutation. These variants have not been previously observed in the Saudi population. In seven clinically diagnosed ADPKD cases but with atypical features, no PKD1 or PKD2 mutations were identified, but rare predicted pathogenic heterozygous variants were found in cystogenic candidate genes including PKHD1, PKD1L3, EGF, CFTR, and TSC2. Conclusions: Mutations in PKD1 and PKD2 are the most common cause of ADPKD in Saudi patients with typical ADPKD.

RESUMO

Breast cancer represents a significant health concern, particularly in Saudi Arabia, where it ranks as the most prevalent cancer type among women. This study focuses on leveraging eXplainable Artificial Intelligence (XAI) techniques to predict benign and malignant breast cancer cases using various clinical and pathological features specific to Saudi Arabian patients. Six distinct models were trained and evaluated based on common performance metrics such as accuracy, precision, recall, F1 score, and AUC-ROC score. To enhance interpretability, Local Interpretable Model-Agnostic Explanations (LIME) and SHapley Additive exPlanations (SHAP) were applied. The analysis identified the Random Forest model as the top performer, achieving an accuracy of 0.72, along with robust precision, recall, F1 score, and AUC-ROC score values. Conversely, the Support Vector Machine model exhibited the poorest performance metrics, indicating its limited predictive capability. Notably, the XAI approaches unveiled variations in the feature importance rankings across models, underscoring the need for further investigation. These findings offer valuable insights into breast cancer diagnosis and machine learning interpretation, aiding healthcare providers in understanding and potentially integrating such technologies into clinical practices.

RESUMO

Breast abscess in males is a rare condition, which accounts for 1%-3% of all documented breast diseases. Males with certain risk factors may develop a breast abscess. The ultrasonographic, mammographic, and pathological characteristics of this case will be highlighted in the report. A 51-year-old morbidly obese Saudi male who is a 160-pack-years smoker presented to our surgical clinic complaining of a right breast mass that presented a long time ago and was changing in size. The mass was painless until 5 days prior to presentation. On physical examination, a firm nonmobile 3 × 4 cm mass was felt at 10-12-o'clock, 1 cm away from the nipple. A bilateral X-ray mammogram and ultrasound were performed with fine needle aspiration and culture. The mammogram of the right breast showed a well-circumscribed subareolar mass with equal density, and it was also associated with overlying skin thickening and relative breast parenchymal edema. The fine needle aspiration grossly showed yellowish-green turbid content followed by turbid blood. The anaerobic culture results showed the gram-positive cocci, Finegoldia Magna. The patient was then instructed to take an antibiotic accordingly and return after 1 week. Fine needle aspiration and culture were performed again after antibiotics and grossly showed 2-3 cc of pus without any growth in culture. Male breast disorders are typically benign, with gynecomastia being the most prevalent, and malignancy being the most serious despite its rarity. Breast abscesses are a challenging clinical condition, and radiologists have a pivotal role in evaluation and follow-up of these lesions.

RESUMO

BACKGROUND: Diabetes mellitus is a chronic disease characterized by a wide range of metabolic problems. The current study sought to assess nutritional habits of Saudi patients with type 2 diabetes (T2D) and to propose recommendations to improve these patients' dietary habits and delay possible disease complications. METHODS: Over a period of three years, (2017-2019) 577 patients with T2D attending the outpatient's diabetic clinics at King Fahd Hospital of the University, Al Khobar, Saudi Arabia were invited to participate in this study. Data of dietary intake were collected by trained nurses using a pretested structured validated semi quantitative food frequency questionnaire. The dietary data were collected using 7-day dietary recall questionnaire. A modified score system that associates dietary habits with glycemic control and lipid profile was used. RESULTS: Overall, a high healthful plant-based diet score was associated with a significant (P = 0.018) reduction in triglycerides (TG) level (mean difference - 3.78%; 95% CI, -0.65% to -6.81%) and a statistically non-significant (P = 0.06) increase in high density lipoprotein (HDL) levels (mean difference 1.87%; 95% CI -0.06-3.84%) in T2D patients from the Eastern Province of Saudi Arabia. Additionally, in our patient group, the prevalence of coronary artery disease, stroke, peripheral artery disease, and chronic kidney disease in T2D patients was 11.3%, 6.2%, 3.3%, and 8.4%, respectively and were higher when compared to the prevalence in the general population. CONCLUSION: The present study showed that adherence to a healthful plant-based diet, when compared to high glycemic index diet, is associated with a favorable outcome in glycemic control and lipid profile in T2D patients. Prior assessment of total diet quality may be beneficial when giving nutritional advice to T2D patients with the possibility of improving glycemic control and lipid profile.

RESUMO

Intragastric balloons are one method of obesity treatment. We report on a 34-year-old man who presented with colicky abdominal pain with nausea and vomiting a year and eight months after intragastric balloon insertion. To evaluate the patient's symptoms, an initial abdominal X-ray was done followed by a computed tomography scan to check the condition of the intragastric balloon. In our case, the patient's pain was not due to the deflated migrating BioEnterics® intragastric balloon (BIB). Thus, no further management was done for it, and the patient was diagnosed with gastroenteritis. Despite that, regular follow-up is recommended to prevent serious complications in the future.

RESUMO

Background The development of axillary lymphadenopathy post COVID-19 vaccine became an area of concern. This needs to be addressed and investigated to provide updated data that could contribute to its management and imaging guidelines. Objectives This study aims to detect possible changes in lymph nodes (LNs) after COVID-19 vaccination, decrease the rate of over-investigation and medical costs, and identify possible predisposing factors that could trigger the development of lymphadenopathy. Methods This was a retrospective cohort study conducted in King Fahad University Hospital, a secondary hospital in Al Khobar, Kingdom of Saudi Arabia (KSA), on a total of 1,257 vaccinated patients who underwent axillary ultrasonography (US) from December 2020 till the second of October 2022. All required data were collected using an Excel sheet and analyzed using Statistical Product and Service Solutions (SPSS, version 21) (IBM SPSS Statistics for Windows, Armonk, NY). Results Out of the 1183 cases, 460 (38.9%) cases had abnormal LNs post COVID-19 vaccine based on US, while LNs were normal in 723 (61.1%) cases. The prevalence of axillary lymphadenopathy was significantly more common in females than males (39.1% of cases in female patients versus 22.2% of cases in male patients (P = 0.049)). In addition, lymphadenopathy was more prevalent among patients who received the COVID-19 vaccine less than four weeks ago, compared to others who received the vaccine four to eight weeks ago, 8-12 weeks ago, and more than 12 weeks ago (100% vs 73.3% vs 34.2% vs 72% (P = 0.001)). Conclusion In conclusion, a significant number of patients were found to have lymphadenopathy after receiving the COVID-19 vaccine. The only predisposing factors identified to be associated with the development of lymphadenopathy were gender (females more than males) and duration since receiving the vaccine (four weeks).

RESUMO

BACKGROUND: Breast cancer patients from the indigenous Arab population present much earlier than patients from Western countries and have traditionally been underrepresented in cancer genomics studies. The contribution of polygenic and Mendelian risk toward the earlier onset of breast cancer in the population remains elusive. METHODS: We performed low-pass whole genome sequencing (lpWGS) and whole-exome sequencing (WES) from 220 female breast cancer patients unselected for positive family history from the indigenous Arab population. Using publicly available resources, we imputed population-specific variants and calculated breast cancer burden-sensitive polygenic risk scores (PRS). Variant pathogenicity was also evaluated on exome variants with high coverage. RESULTS: Variants imputed from lpWGS showed high concordance with paired exome (median dosage correlation: 0.9459, Interquartile range: 0.9410-0.9490). After adjusting the PRS to the Arab population, we found significant associations between PRS performance in risk prediction and first-degree relative breast cancer history prediction (Spearman rho=0.43, p = 0.03), where breast cancer patients in the top PRS decile are 5.53 (95% CI 1.76-17.97, p = 0.003) times more likely also to have a first-degree relative diagnosed with breast cancer compared to those in the middle deciles. In addition, we found evidence for the genetic liability threshold model of breast cancer where among patients with a family history of breast cancer, pathogenic rare variant carriers had significantly lower PRS than non-carriers (p = 0.0205, Mann-Whitney U test) while for non-carriers every standard deviation increase in PRS corresponded to 4.52 years (95% CI 8.88-0.17, p = 0.042) earlier age of presentation. CONCLUSIONS: Overall, our study provides a framework to assess polygenic risk in an understudied population using lpWGS and identifies common variant risk as a factor independent of pathogenic variant carrier status for earlier age of onset of breast cancer among indigenous Arab breast cancer patients.

RESUMO

Aim: The indigenous Arab population is underrepresented in genomic studies and the landscape of actionable pharmacogenomic variants among Arab breast cancer patients remains unclear. Materials & methods: Exome sequencing was performed on 220 unselected Arab female breast cancer patients and germline variants in CYP2D6 and DPYD were profiled using a deep learning method. Results: In total, 13 (5.9%) patients had clinically actionable results and 56 (25.5%) carried an allele in DYPD or CYP2D6 with unknown impact on drug metabolism. In addition, four unique novel missense variants were discovered, including one in CYP2D6 (p.Arg64Leu) with high predicted pathogenicity. Conclusion: A nontrivial subset of Arab breast cancer patients can potentially benefit from pretreatment molecular profiling, and further study is needed to improve characterization of the pharmacogenomic landscape.

RESUMO

A uterine/ovarian artery pseudoaneurysm is a rare complication of pelvic surgical interventions such as oocyte retrieval. This complication can be life-threatening due to the risk of rupture and blood extravasation. We report the case of a 30-year-old, nulliparous, married woman with a rare uterine/ovarian artery pseudoaneurysm due to in vitro fertilization. The patient has a history of sickle cell disease and primary infertility with multiple failed ovulation induction. She presented to the emergency department (ED) with hypotension following ovum retrieval for in vitro fertilization. Upon examination, we noted that the patient had tense ascites. A focused assessment with sonography in trauma (FAST) in the ED revealed internal bleeding. The diagnosis of a uterine artery pseudoaneurysm was established. She underwent an exploratory laparotomy to control bleeding due to her instability. Computed tomography and FAST scans help make an accurate diagnosis, and this case highlights that early intervention by embolization is essential to stabilize the patient and improve patient outcomes.

RESUMO

Reports of the incidence of the cyst of Montgomery, a rare condition of the breast, affecting mainly adolescent female, are scarce in the literature. This cyst develops from an obstruction of the small papular projections at the edge of the areola called Montgomery tubercles. It could be a simple asymptomatic mass or an inflamed symptomatic mass. We report two cases encountered this year. The first case was a 15-year-old female who complained of bilateral breast pain and a right breast mass. Laboratory tests were unremarkable. A diagnosis of noninflamed Montgomery cyst based on clinical and sonographic examination was made. An antibiotic was recommended. The second case was a 13-year-old female who complained of pain and swelling with redness in the right breast. Laboratory tests were unremarkable. Sonographic examination revealed a right retroareolar cyst containing turbid echogenicity with surrounded hyperemia. A diagnosis of inflamed Montgomery's cyst was made. Medical treatment was successful without any surgical intervention. Both patients had favorable outcomes at follow-up visits. This stresses the importance of a proper recognition of the pathology, incidence, diagnosis and management of the cyst of Montgomery in the pediatric age group.

RESUMO

AIM: The frequency of the Right Posterior Sectional Bile Duct (RPSBD) hump sign in cholangiogram when it crosses over the right portal vein known as Hjortsjo Crook Sign and the bile duct anatomy are studied. Knowledge of the implication of positive sign can facilitate safe resection for both bile duct and portal vein. METHODS: Prospectively, we included 237 patients with indicated ERCP during a period from March 2010 to January 2015. RESULTS: The mean age (±SD) and male to female ratio were 38.8 (±19.20) and 1 : 1.28, respectively. All patients are Arab from Middle Eastern origin, had biliary stone disease, and underwent diagnostic and therapeutic ERCP. Positive Hjortsjo Crook Sign was found in 17.7% (42) of patients. The sign was found to be equally more frequent in Nakamura's RPSBD anatomical variant types I, II, and IV in 8.4% (20), 6.8% (16), and 2.1% (5), respectively, while rare anatomical variant type III showed no positive sign. CONCLUSION: Hjortsjo Crook Sign frequently presents in RPSBD variation types I, II, and IV in our patients.

RESUMO

Acute epiploic appendagitis is a relatively rare cause of lower abdominal pain that clinically mimics other acute abdomen conditions that require surgery such as acute diverticulitis or appendicitis. Here, we report a case of a 50-year-old lady who presented with an unusual lower abdominal pain. Awareness of such a clinical condition with its characteristic imaging findings is important to avoid costly hospitalization, unnecessary antibiotic courses, and the morbidity and mortality associated with surgical procedures.
