Failure Rate of Porcelain-Fused-to-Metal (PFM) Crowns in Taiz, Yemen: A Cross-Sectional Analysis
Get PDFObjective: This study aimed to determine the causes of failure in porcelain-fused-to-metal (PFM) dental crowns in Taiz Governorate, Yemen.
Methods: A descriptive cross-sectional analysis was conducted and recruited approximately 40 participants by distributing a questionnaire to dentists and dental technicians.
Results: Most (70%) of the participants were male, and 50% had a bachelor’s degree. Experience levels ranged from 5.0 to 47.5 years; those with more than 5 years of practice accounted for 52.5%. Most of the time, crown failure was due to tooth preparation that wasn\u27t right for the crown (100% of the time), an unclear abutment line (100% of the time), crowns that didn\u27t fit properly (90% of the time), poor oral hygiene (70% of the time), and gum infection (57.5% of the time). Psychological factors (75%) and material quality (100%) could predict crown longevity. Furthermore, 90% estimated that inadequate sealing and poor adhesive cement were the cause of failure. Also meriting mention is that 75% agreed that not the patient but rather lack of proper installation and high-quality adhesive cement, was responsible for failure. Additionally, the study highlighted that dentists and technicians were equally responsible for shared causes of common failure, as indicated by all of the participants (100%).
Conclusion: The study\u27s results indicate that various factors contribute to PFM crown failure. This means that it depends a lot on the right clinical procedure, the material used, and how well the dental professionals work together. Addresses to these factors might improve the long-term success of PFM restorations
The Effect of Anticoagulants on Stoma: A Case Study at Al-Wali Hospital, Aden, Yemen
Get PDFThis case report describes the complications of anticoagulant therapy in a 64-year-old patient who had since had rectal cancer and persistent colostomy due to surgery after. During anticoagulation therapy for potential venous thrombosis, the patient was treated for bilateral lower limb edema and colostomy hemorrhage and had signs of generalized problems. Managing anticoagulation in these patients is especially problematic because of the background of the concomitant risk of thrombosis bleeding, especially at the stoma site, which is rich in vasculature and is easily traumatized or contaminated. This report presents the patient\u27s clinical features, diagnostic approach, therapeutic options, and outcome. The anticoagulation of stoma patients is viewed from a broader perspective, highlighting the role of individual therapy and a multidisciplinary approach. In view of this situation, a specific, research-evidence-based recommendation regarding the management of anticoagulants in the stoma patients for the purpose of having the efficacy leading to safety would be warranted
Pulp Capping Agents in Operative Dentistry: an Updated Review
Get PDFBackground: Pulp capping is a restorative technique that helps preserve the tooth pulp after significant injury during cavity preparation, preventing it from degenerating when it was exposed or nearly exposed.
Objective: The aim of this article is to review the literature to assess the current trends and future directions of dental pulp capping materials and it mainly focus on the classification of materials along with their mechanisms.
Methods: A comprehensive search was made to identify relevant previous studies in this area in PubMed and Google Scholar databases.
Results: The procedure of vital pulp capping primarily depends on the ability of dental pulpal tissue to heal. A wide array of materials has been used for pulp capping. Calcium hydroxide and Mineral Trioxide Aggregates (MTA) are the most commonly used pulp capping materials in dentistry, and they have had significant clinical success.
Conclusion: In recent years various other materials like Bone morphogenic protein, Bio dentin, Lasers are also introduced clinically. Further in vitro and in vivo studies are necessary to examine and validate about calcium ion releasing ability, together with the cytotoxic effect and the clinical significance of these next-generation materials
Serum Uric Acid and LDL-C in Yemeni Type 2 Diabetic Men: Insights from a Conflict-Zone Case-Control Study
Get PDFالخلفية: يُعد داء السكري من النوع الثاني (T2DM) مصدر قلق كبير للصحة العامة نظرًا لارتباطه بمختلف عوامل الخطر القلبية الوعائية. من بين هذه العوامل، اكتسب ارتفاع مستويات حمض اليوريك في المصل مؤخرًا اهتمامًا كعامل محتمل يُسهم في أمراض القلب والأوعية الدموية.
في حين أن دور حمض اليوريك في اضطراب شحميات الدم لا يزال محل جدل، إلا أن البيانات من سكان الشرق الأوسط لا تزال نادرة.
الهدف: هدفت هذه الدراسة إلى دراسة العلاقة بين مستويات حمض اليوريك في المصل وبعض عوامل الخطر القلبية الوعائية، بما في ذلك معايير ملف الدهون، لدى مرضى داء السكري من النوع الثاني الذكور.
الطرق: شملت هذه الدراسة، المُكيفة مع التضارب، 100 رجل يمني (50 من داء السكري من النوع الثاني، و50 من مجموعة الضبط) في الضالع (2025). تم تحليل دم الصائم للكشف عن مستوى حمض اليوريك (URA) (يوريكاس-PAP)، والدهون، والجلوكوز باستخدام بروتوكولات تعمل بالطاقة الشمسية وأنابيب باريكور. النتائج: أظهر مرضى السكري من النوع الثاني ارتفاعًا في مستوى شحميات الدم غير المشبعة (6.56 مقابل 5.13 ملغ/ديسيلتر، *p* <0.001) وكوليسترول LDL-C (114.9 مقابل 72.9 ملغ/ديسيلتر، *p* <0.001)، مع ارتباط قوي بين شحميات الدم غير المشبعة وكوليسترول LDL-C (β=0.58، *p* = 0.002). لم تُظهر الدهون الثلاثية أي ارتباط (*p* = 0.147)، ويرجح أن ذلك يعود إلى انخفاض تناول الفركتوز.
الخلاصة: يُنبئ ارتفاع شحميات الدم غير المشبعة بشكل مستقل بمستوى شحميات الدم غير المشبعة لدى الذكور اليمنيين المصابين بالسكري من النوع الثاني، مما يشير إلى أن شحميات الدم غير المشبعة تُعدّ مؤشرًا قابلًا للتعديل لخطر الإصابة بأمراض القلب والأوعية الدموية.Background: Type 2 diabetes mellitus (T2DM) is a major public health concern due to its association with various cardiovascular risk factors. Among these risk factors, elevated serum uric acid levels have gained increasing attention as a potential contributor to cardiovascular disease (CVD). While uric acid’s role in dyslipidemia is debated, data from Middle Eastern populations remain scarce.
Objective: This study aimed to investigate the association between serum uric acid levels and certain cardiovascular risk factors, including lipid profile parameters, in male patients with T2DM.
Methods: This case-control study, adapted for conflict-zone conditions, enrolled 100 Yemeni males (50 T2DM and 50 controls) in Al-Dhalea. Fasting blood was analyzed for SUA (uricase-PAP), lipids, and glucose using solar-powered and Barricor tube protocols.
Results: T2DM patients had higher SUA (6.56 vs. 5.13 mg/dL, p<0.001) and LDL-C (114.9 vs. 72.9 mg/dL, p<0.001), with a strong SUA-LDL-C correlation (β=0.58, p=0.002). Triglycerides showed no association (p=0.147).
Conclusion: Elevated SUA is independently associated with LDL-C in Yemeni T2DM males, suggesting SUA as a modifiable CVD risk marker
Awareness and Knowledge of Drug-Laboratory Test Interferences among Medical Laboratory Technologists in Yemen
Get PDFBackground: Drug-laboratory test interactions (DLTIs) can mislead the health care professionals and provide incorrect information regarding the patient’s health status. To date there are no specific courses in medical laboratory science curricula in Yemen that specialize in this topic.
Objective: This study aims to reveal the knowledge about DLTIs among laboratory technologists in Yemen.
Methods: A cross-sectional study was conducted in 11 governorates in Yemen to evaluate the awareness about DLTIs among laboratory technologists. An electronic questionnaire was distributed, and responses were analyzed.
Results: A total of 396 laboratory technologists participated in this study. The majority of respondents (96.4%) reported that certain medications can affect laboratory test results, and 89.4% of participants showed knowledge about common medication interferences, but specific drug class awareness varied considerably. Only 53 (13.3%) had received formal training on drug-laboratory test interference and scored the highest in the knowledge questions.
Conclusion: Formal training on DLTIs is important to ensure accurate laboratory test results
Coagulation Profile and Platelet Indices in Yemeni Adults with Type 2 Diabetes: A Cross-Sectional Study in Aden Governorate
Get PDFBackground: Type 2 diabetes mellitus (T2DM) induces a hypercoagulable state that increases thrombotic risk.
Objective: This study evaluated coagulation parameters and platelet indices in Yemeni adults with T2DM and their correlation with glycemic control.
Methods: A hospital-based cross-sectional study was conducted on 140 T2DM patients and 100 healthy controls from major hospitals in Aden Governorate between January and February 2025. Coagulation tests (PT, APTT) were performed using STA-R Evolution, and platelet indices (MPV, PDW) were analyzed via Sysmex XN-550. Glycemic control was assessed by HbA1c. Statistical analysis was performed using SPSS v26.
Results: Most patients (86%) had poor glycemic control (HbA1c ≥ 7%). Diabetic patients demonstrated significantly prolonged prothrombin time (PT) compared with healthy controls (13.69 ± 1.74 sec vs. 12.10 ± 1.20 sec, p < 0.001), shortened APTT (31.38 ± 4.16 sec vs. 35.20 ± 3.50 sec, p < 0.001), and elevated MPV (9.03 ± 0.92 fL vs. 8.70 ± 1.10 fL, p = 0.015) and PDW (16.8 ± 2.1% vs. 15.2 ± 1.8%, p = 0.01) compared to controls. A strong positive correlation was found between HbA1c and MPV (r = 0.52, p < 0.001). An MPV cut-off > 11.5 fL predicted thrombotic risk with 78% sensitivity and 85% specificity (AUC = 0.82).
Conclusion: Yemeni T2DM patients demonstrate significant hemostatic abnormalities strongly linked to poor glycemic control. MPV represents a cost-effective, accessible marker for thrombotic risk stratification. We propose its integration into routine diabetic care protocols in Yemen and similar resource-limited settings.
THE EVOLUTION OF APACHE HADOOP: A TECHNICAL JOURNEY FROM WEB CRAWLING TO ENTERPRISE COMPUTING
Get PDFThis paper systematically analyzes Apache Hadoop\u27s technological evolution, tracing its transformation from a web crawling subsystem to a comprehensive enterprise computing platform. Beginning with its origins in Google\u27s foundational papers on the Google File System (GFS) and MapReduce, we examine the critical architectural decisions and technical innovations that shaped Hadoop\u27s development across its major releases. The study talks about important technical milestones, such as how it came out of the Nutch project in 2006, how Yahoo! put it into production in 2008, how the stability-focused 1.0 release came out in 2011, how the groundbreaking YARN architecture came out in 2013, and how the security-enhanced 3.0 version came out in 2017. Our study shows how each stage of development solved a different problem related to distributed computing while also making Hadoop more useful than just being used for the web. We show how architectural changes in resource management, data storage efficiency, and processing flexibility helped Hadoop grow from a specific MapReduce implementation to a flexible distributed computing framework that can handle a wide range of business workloads. The research provides valuable insights into the technical considerations that drive distributed system evolution and offers lessons for future large-scale computing platforms
Enhanced Health (Record) Information Management System Using Mobile Application Development Framework
Get PDFAn essential component of effective healthcare delivery is health record management. Although, conventional paper-based systems have long been the standard, they have a number of drawbacks, including inaccuracy, inefficiency, and a lack of accessibility. The adoption of a web-based health record management system proved to be a viable replacement for the paper-based system for handling medical records. However, there were certain obstacles along the way, including concerns about data security and privacy, data loss during the shift from paper to the web-based system, a lack of inclusivity, unauthorised access to patient records, and limited access to patient records because of inadequate internet access and facilities in Nigeria. This dissertation therefore reviewed the observable limitations of the existing system and proposed the development of a mobile patient’s health record management system using mobile application development framework. The system was developed using Android Studio integrated development environment (IDE) and the Java programming language, with SQLite database and rapid application development methodology (RAD) which is an Agile method for enhanced program development especially for mobile application development. The new system outperformed the existing web-based hospital record management system in terms of speed, efficiency, robustness portability, data security and integrity as it enables both patients and doctors to access and book appointments remotely without having to go physically to the hospital saving man-hour and boosting the morale of both staff and patients.
