Published: May 2024

The current study aims to verify whether students’ motivation towards learning math and their academic achievement is affected by using (AR) applications in learning math. The study followed the quasi-experimental approach to achieve the objectives. The sample is (46) students in seventh grade distributed as two groups: control and experimental, (23) students in each. AR-based applications were used to explain the educational content to the first group, while the second group was taught using conventional methods. Two instruments were developed to collect data for the study: a scale of motivation towards learning math and an achievement test in math. The results indicated that the experimental group students’ motivation towards learning math was significantly enhanced after treatment, and their academic achievement was apparently improved. Accordingly, the study recommends using (AR) applications in teaching math topics to create a more interactive learning environment that may enhance learners’ motivation and improve their academic achievement.

Borrelia burgdorferi
Authors: Gaetano Andrew , Danka Elizabeth
Published: May 2024

Since its recent discovery in the late 1970s, Lyme Disease (LD) has been a growing public health concern, especially in the United States where it accounts for the majority of vector-borne infections each year. The causative agent, Borrelia burgdorferi, is transmitted to humans through the bite of an infected Ixodes tick. This pathogen uses many unique mechanisms to both shield itself from the host immune response and cause disease. Clinically, LD presents in successive phases, with each increasing in severity as the bacterial cells migrate to new tissues and organ systems. On the epidemiological and ecological fronts, limitations in reporting, ecological changes, and a lack of public support hinder accurate surveillance and enhance the spread of the disease. The goal of this literature review is to increase public knowledge of B. burgdorferi, its vector, and the disease it causes, along with suggesting preventative measures to protect individuals who reside in high-risk areas. A collective and coordinated public health effort represents our greatest chance of restraining the LD-causing pathogen.

Authors: Boukhalkhal Said Hicham , Ihaddoudène Abd Nacer Touati , Neves Luis Filipe Da Costa , Saidani Messaoud
Published: May 2024

This paper presents a new analytical approach for calculating the stiffness of the loaded face of a rectangular hollow section RHS column in beam-column connections with and without concrete infill, as well as with flush and extended endplates, to determine the behavior curve of these types of connections. The approach, based on Eurocode 03's component method, offers efficient analytical formulas for accurately determining the loaded face's stiffness. A comparison with existing methods demonstrates its remarkable simplicity and efficiency, allowing a simple beam model to represent the RHS column's behavior with all relevant parameters considered. Comparison of the new approach to existing ones from the literature demonstrates their reliability and efficiency. Furthermore, when compared to 32 experimental tests presenting nearly the entire range of probable connection configurations, as well as attachment techniques commonly used in construction practice, the margin of error does not exceed 12 percent on average and a maximum of less than 25 percent.
An integrated intermodal freight transportation system to avoid container supply chain disruptions in Chattogram Port of Bangladesh
Authors: Saha Razon Chandra , Sabur H. M. Abdus , Saif Tarafder Md. Ruhul
Published: May 2024

An integrated intermodal freight transportation system is a derived demand to transport shipping containers from/to the seaport to/from the hinterland, instead of undertaking cargo loading and unloading activities in port-protected areas. The concept of the intermodal system is to transfer containers to nearby hinterland nodes, such as dry ports, inland rail, road, and river terminals as a part of port development, as well as increasing port efficiency and productivity. Lloyd’s List ranked Chattogram Port as the 67th busiest container port in the world as per container port throughput in 2022. Chattogram Port has small-scale intermodal facilities for off-docks/ICDs in the port city only. In addition, a pure intermodal system has been developed by one rail ICD in the capital city, Dhaka, and two RICTs nearby Dhaka, but less than 5 % of port throughput. A large-scale intermodal for serving the major cities, SEZs, EPZs, and industrial areas is absent due to planning and policy problems, as well as the unavailability of intermodal infrastructure and network. Due to an improper hinterland intermodal chain, the port faced container supply chain disruptions at the port yard and exceeded port capacity, resulting in container vessel congestion at the outer anchorage of Chattogram Port. By developing rail and road infrastructure, and utilizing natural river connectivity, it is possible to develop road, rail, and river intermodal systems, and shape an integrated intermodal freight transportation system to avoid container supply chain disruptions in Chattogram Port. To develop an integrated intermodal system, this research chose a quantitative research methodology for port throughput data analysis and forecasting future throughputs that are advanced to the intermodal model for Chattogram Port. Overall, this paper aims to develop an integrated intermodal freight transportation system to support Chattogram Port to keep and increase the record of port productivity, efficiency, and competitiveness actively.
Highlights

Intermodal system is a derived demand for managing hinterland and port terminals of a seaport that needs to be implemented in Chattogram Port
Container supply chain disruptions to be avoided to increase the port productivity and efficiency
Inland intermodal connectivity will help to increase hinterland of a seaport
It is necessary to develop an integrated intermodal freight transportation system to support Chattogram Port to keep and increase the record of port productivity, efficiency, and competitiveness globally

It is a distinct type of AML characterized by chromosomal translocations involving the retinoid acid receptor (RAR-A) gene on chromosome 17. It accounts for 20-25% of all AML cases. The aim of this study was to describe the diagnostic features of pediatric APL and the result with ATRA and ATO based protocol.
Methods: It was a descriptive type of cross-sectional study with purposively selected 10 newly diagnosed APML patients treated in the Pediatric Oncology unit of the Department of Pediatrics in CMH Dhaka during the period of 2018 to 2022. Diagnosis of all patients were done by aspirating bone marrow morphology and cytogenetic t(15:17) or t(11:17) transcript. Informed written consent was taken from parents. Data were collected by semi-structured questionnaire and analyzed by Statistical Package for Social Sciences (SPSS version 25).
Results: Among 10 respondents median age was 4.2 years with female predominant (60%). Most common clinical presentations at diagnosis were fever (100%), bleeding manifestations (100%), Hepatomegaly (90%) bony tenderness (90%), splenomegaly (70%), and lymphadenopathy (70%). Almost all the patients had low Hb & low platelet count & WBC were variable. Cytogenetic analysis revealed 90% had PML/RARA positive & 30% had FLT3/ITD positive. All of these patients were treated with trans-retinoic acid (ATRA) based treatment, which led to 80% cases ATRA syndrome. Other common toxicities noticed febrile neutropenia (50%), severe headache (30%), hyperpigmented skin (10%), pseudotumor cerebri (10%) and others. There were 10% relapse cases, which later proceeded to relapse protocol and were in remission. The remaining 90% of patients were alive and in remission until the last day of follow-up.
 Conclusion: With ATRA-based treatment overall survival is good achieved remission and only 10% of patients developed relapse.

Background: Classification based on ascitic fluid protein has been challenged on several occasions in diverse clinical situations, including cirrhotic patients on extended diuretic treatment, cardiac ascites, 1/3 individuals with malignant ascites, spontaneous bacterial peritonitis, and even normal ascitic fluid.
Objective: The study’s objective was to observe the role of serum ascites albumin gradient (SAAG) in diagnosing Ascites.
Methods: This cross-sectional observational study was conducted at the Department of Medicine, Sylhet M.A.G. Osmani Medical College Hospital, Bangladesh. with a total of 100 participants with ascites following the inclusion and exclusion criteria of the study.
Result: The most prevalent cause of ascites was cirrhosis, observed in 56% of the participants. Among the 56 cirrhosis patients, mean ± S.D. values of AFTP, AFAlb, SAlb, and SAAG were 2.1±1.2, 0.8±0.6, 3.1±0.7, and 2.2±0.7 respective units accordingly. According to ascitic fluid albumin values, a statistically significant relation was observed between cirrhosis and tuberculosis (P<0.01) and cirrhosis vs malignancy (P<0.01) cases. According to serum ascitic albumin gradient values, a similar significant association was also found between cirrhosis vs tuberculosis (P<0.01) and cirrhosis vs malignancy (P<0.01) cases.
Conclusion: SAAG is an essential laboratory tool for the correct aetiological diagnosis of ascites.

Refractory Gastroesophageal Reflux Disease: Scopes Beyond PPI
Authors: Haque Mohammad Majharul , Jannat Syeda Nur E , Salimullah ASM , Saha Amitav , Datta Ponkaj Kanti
Published: May 2024

Gastroesophageal reflux disease (GERD) is a very common GI disorder where the reflux of gastric contents into the esophagus causes symptom generation. PPI is the principal weapon to fight against GERD. An empiric course of PPI therapy is a cost-effective strategy for managing GERD. But sometimes, PPI can only do so much if taken correctly. As PPI does not reduce the number of reflux, other measures, including lifestyle modification, are required to get relief of GERD symptoms. Most patients respond to 8 weeks of PPI therapy, but 20-40% do not respond or respond partially. While these patients are labeled as having refractory heartburn, many do not have GERD or have not been treated adequately. So, alternative etiology must be considered when patients are refractory to PPI. Endoscopy of upper GIT should be done initially in case of the presence of alarm symptoms and when considered refractory to exclude other conditions. If endoscopy reveals no abnormality, then esophageal function tests like esophageal manometry, 24 hrs ambulatory pH monitoring, and mucosal impedance test can be considered to exclude other related conditions. Endoscopic and surgical treatment options can also be considered in particular cases.

Published: May 2024

ANCA vasculitis, caused by antibodies named ANCA (anti-neutrophilic cytoplasmic autoantibodies), is an autoimmune disorder affecting small blood vessels of the body. Among p-ANCA and c- ANCA, c-ANCA (cytoplasmic ANCA) usually targets proteinase three inside neutrophils, causing inflammation of blood vessels. Herein, we report a case of a 56-year-old female patient with c- ANCA-associated vasculitis. The patient presented with a localized skin thickening on the medial aspect of the left thigh and an oral ulcer. Skin biopsy shows erythema induratum (nodular vasculitis). After several investigations, we found c-ANCA positive and concluded the diagnosis as c-ANCA-associated vasculitis. We treat the patient with injectable methylprednisolone, injectable cyclophosphamide, and Mesna. Then we gave oral mycophenolate mofetil and prednisolone.

The use of social media has increased in the last few years. Social media has a negative impact on a person's self-esteem because they make social comparisons based on what they see on social media. This study aims to examine the relationship between the level of social media use and the level of self-esteem in young adults. The study used a cross-sectional approach, and the population in this study was college students (19-20 years old) in Malang, Indonesia. The sample consisted of 96 respondents, selected using purposive sampling. Respondents filled out the Bergen Social Media Addiction Scale (BSMAS) questionnaire and the Coopersmith Self-esteem Inventory (CSEI). Data were analyzed using the Spearman Rank correlation test in SPSS. The results showed that 57.3% of respondents were at the alert category level of social media use, and 63.5% of respondents had very low self-esteem. The correlation test showed a negative relationship between social media use and self-esteem (p-value = 0.044; r = -0.206). The strength of the relationship is weak and has a negative direction, meaning that the higher the level of social media use, the lower the self-esteem level will be. Alert-level social media use among young adults has an effect on low levels of self-esteem.

Among Indonesian society sweet tea is commonly recognized as an agent to help individuals experiencing hypoglycaemia before they are taken to the hospital. However, tea contains chemical compounds that can lower blood glucose levels. The aim of this study is to assess the effectiveness of sweet tea in managing hypoglycaemia. A literature review method was employed, focusing on journals related to blood sugar levels, blood glucose, postprandial, hypoglycaemia, tea, green tea, black tea, Chinese tea, hypoglycaemia management guidelines, diabetes, and emergencies. Journals were sourced from the internet and limited to the past 15 years. Based on the review results, it is known that the administration of 15 grams of oral monosaccharide glucose can increase blood glucose levels by 2.1 mmol/L in 20 minutes, while 20 grams of oral glucose can increase blood glucose levels by 3.6 mmol/L in 45 minutes. Meanwhile, the administration of 3.3 grams of green tea can decrease postprandial blood glucose levels to 88.95 mmol/dL after 2 hours, the administration catechins of green tea for 369.14 mg actually decreases postprandial blood glucose levels to 88.95±6.13 mg/dL, and the administration of 32 grams of tea extract lowers postprandial blood glucose levels to 81.0 mg/dL. The conclusion drawn is that the administration of oral glucose to hypoglycaemic patients may be less effective when given with tea because tea contains polyphenols that inhibit α-amylase and α-glucosidase, activate glycolytic enzymes, thus inhibiting the process of glucose catabolism.
