  • Application of Artificial Intelligence in Forecasting: A Systematic Review

    Purpose: The aim of this reach is to identify how Artificial Intelligence (AI) could be used in enhancing forecasting to achieve more accurate outcomes. The research also explores the influence that forecasting has on global economy and the reasons why it needs to be accurate. Also, the research explains various pitfalls identified in forecasting. Method: This research implements two research approaches which are review of literature and formulation of hypotheses. Seven hypotheses are created. Findings: AI, when integrated with other technologies such as Machine Learning (ML) and when provided with the right computer power, yields much more accurate results than many other forecasting methods. The technology is costly, however, and it is prone to cyber-attacks. Conclusion: The future of business is highly reliant on forecasting, which directly impacts the global economy. But, not every business will have the power to own the forecasting technology due to the cost, and business will need to increase security to protect the forecasting systems.

  • Esophageal cancer in Bobo-Dioulasso (Burkina Faso): epidemiological, clinical, endoscopic and anatomopathological aspects

    Introduction. Our study aims to strengthen the literature on esophageal cancer in Burkina Faso by assessing its endoscopic frequency and describing its epidemiological, anatomical-clinical and endoscopic characteristics. Patients and Methods: This was a descriptive cross-sectional study conducted from January 1, 2015 to June 30, 2018. Included in this study were all patients who had upper gastrointestinal fibroscopy (UGIF) with biopsy, and in whom esophageal cancer was confirmed histologically. The variables studied were: age, sex, main circumstance of diagnosis, endoscopic appearance, and histological type, as well as risk factors. Results: During the study period, 29 cases of esophageal cancer were diagnosed, with an average endoscopic incidence of 8.3 cases/year. The average age was 58.34 years. There were 17 (58.6%) males, or a sex ratio of 1.5. The definite risk factors of alcohol consumption and active smoking were present in 31.0% of patients. The average duration of consultation was 65.8 days, and the main symptom at diagnosis was dysphagia (72.4%). The preferred location was the lower third for nearly three-quarters of tumors; and the budding form was dominant (56.3%). At histology, squamous cell carcinoma was the dominant type (65.5%). Conclusion: This study shows us an increase in the average annual incidence of esophageal cancer in Bobo-Dioulasso. It mainly affects males from the age of 50, with clinical, endoscopic and histological characteristics similar to those found in the literature. The great delay in diagnosis limits the therapeutic options for this cancer with a formidable prognosis.

  • Vulvar lesion in Crohn’s disease: a new case report

    The mucocutaneous manifestations are, with the osteo-articular attacks, the most frequent of the extradigestive attacks of the Crohn’s disease. While some of these events evolve alongside the digestive disease, others evolve on their own. Sometimes they can even precede the appearance of intestinal manifestations by several months, which then poses diagnostic problems. Recto-vaginal fistulas and ovarian involvement in Crohn’s disease have been widely reported in the literature (1; 2). However, there are few series in the literature reporting the genital complications of CD, let alone regarding vulvar lesion. We report a new case of vulvar lesion in Crohn’s disease.

  • VITAMIN D DEFICIENCY IN CHILDREN AGED 6 – 11 AT VIETNAM NATIONAL CHILDREN’S HOSPITAL

    Objective: Describe the situation of vitamin D deficiency in children aged 6 – 11 years at Vietnam National Children’s Hospital. Method: Cross-sectional study. Results: In 155 healthy children in the study, vitamin D deficiency (25(OH)D serum level < 50 nmol/l) was 23.9%. Common clinical symptoms of vitamin D deficiency were long bone pain (32%) and low ionized calcium level (83.8%). There was inverse linear correlation between vitamin D level, weight-for-age z score (WAZ) (r= –0.266 and p

  • Dietary intakes, nutrition status and micronutrient deficiency in picky eating children under 5 years old in the Vietnam National Hospital of Pediatrics

    Background: Recently, picky eating behaviors have become more and more common in Vietnam. Early identification of nutritional deficiencies through assessment of nutritional status and dietary intake is important to be able to intervene in time to help children optimum in growing physically and cognitively. Objective: The aim of this study was to evaluate dietary intake of under five years old children with picky eating behavior and the consequences of these diets on their nutrition status. Methods: Dietary intake was assessed using 24-hour dietary recall for 124 under five years old who presented with picky eating behavior at Vietnam National Hospital of Pediatrics. Nutrients intakes were calculated using validated dietary analysis software and compared with age-appropriate Vietnam Recommended(Recommended Nutrient Intakes- RNI). Nutrition status was assessment follow WHO guideline 2009, micronutrients deficiency was evaluated based on laboratory tests. Results:84.7% of the children had an unbalanced diets, lacking in overall energy intake(70-90% of RNI:48 and ≤ 50%: 19%). Prevalence of stunting (32.3%), under weight (28.2%), wasting (13.7%) and micronutrients deficiency was high. Conclusions: Children with picky eating behavior had high prevalence of inadequate diet, malnutrition and micronutrient deficiencies. Early identification and treatment of picky eating behavior in children is needed to prevent malnutrition.

  • Research on Rate Monotonic Algorithm and Schedulability Analysis in Real-Time System

    Rate monotonic scheduling algorithm (abbr. RM) is one of the main algorithms in real-time systems, but its operation efficiency is low relatively. In this paper, two-level scheduling method is used to improve the operational efficiency of RM algorithm, and the basic principle of computer processor in real-time system is analyzed, and the RM scheduling algorithm is implemented concretely. Considering the shortcoming of RM algorithm, a modified RM algorithm based two-level scheduling strategy is proposed. As a result, the performance and reliability of real-time system is increased, and the applicability of the method is widened.

  • Leakage reduction in water supply system through the adjustment of its hydraulic efficiency

    The present paper provides a pilot example for water networks managers and operators intending to adjust the hydraulic condition of a pressurized water system to operations conditions with the objective to improve its efficiency. For this aim, a hydraulic modeling methodology has been applied and combined with site inspection, and field measurements. The selected water system operates under particular topographic and operational conditions and suffers from major problems making the system unable to deliver water with the designed volume to the regional reservoir. The system is studied under both steady and unsteady conditions. The study shows benefits of the proposed methodology in terms of water loss reduction which allows enhancing the hydraulic performance of the system. Consequently, the adjustment of a water system to fit with the real operations conditions has improved the hydraulic reliability and efficiency of the system. The novelty of this paper is two-fold. First, it gathers field measurements and hydraulic modeling. Second, it forecasts and measures the efficiency of proposed rehabilitation works by checking the performance of the water system. Therefore, the paper results can be useful to researchers in hydraulics who need an identification of relevant studies, as well as to practitioners interested in understanding the available methods, techniques and tools and their applicability level in real case studies.

  • New progress in endoscopic treatment of esophageal tracheal fistula

    Esophageal tracheal fistula is a pathological communication between the esophagus and the trachea and/or bronchus. It is caused by the progression of malignant tumors such as esophageal cancer and lung cancer, as well as radiotherapy and chemotherapy. Once the esophageal tracheal fistula is diagnosed, it needs immediate treatment to block the fistula as soon as possible, relieve symptoms and improve the quality of life of the person. Digestive endoscopic minimally invasive interventional techniques, represented by esophageal stents, are an important means of treating esophageal fistula. In this study, the esophageal stent type selection, placement method and efficacy in the treatment of esophageal tracheal fistula, and the application of other digestive endoscopy techniques is summarized.
