Published: March 2024

INTRODUCTION: Malaria, an infectious illness spread by mosquitoes, is a serious hazard to humans and animals, with an increasing number of cases recorded yearly. Prompt and precise diagnosis, as well as preventative actions, are critical for effectively combating this condition. Malaria is now diagnosed using standard techniques. Microscopy of blood smears, which consists of small pictures, is used by trained specialists to identify diseased cells and define their life phases. The World Health Organisation (WHO) has approved this microscopy-based malaria diagnostic method. Drawing a blood sample from the finger, pricking it, spreading it onto a clean glass slide, and allowing it to dry naturally are all steps in the method. Thin blood smears were previously used to identify parasites under the microscope, but thick blood smears are utilized when parasite levels are low.
OBJECTIVES: Due to its reliance on medical knowledge, high prices, time-consuming nature, and unsatisfactory outcomes, this technique has significant disadvantages. However, as deep learning algorithms progress, these activities may be completed more effectively and with fewer human resources.
METHODS: This study demonstrates the usefulness of transfer learning, a type of deep learning, in categorizing microscopic pictures of parasitized versus uninfected malaria cells. Six models were evaluated using the publicly accessible NIH dataset, proving the usefulness of the suggested technique.
RESULTS: VGG19 model fared better than its competitors, obtaining 95.05% accuracy, 92.83% precision, 96.88% sensitivity, 93.46% specificity, and 94.81% F1-score.
CONCLUSION: This categorization of malaria cell photos will benefit microscopists in particular, as it will improve their workflow and provide a viable alternative for detecting malaria using microscopic cell images.

Published: March 2024

INTRODUCTION: The Graph Coloring Problem (GCP) involves coloring the vertices of a graph in such a way that no two adjacent vertices share the same color while using the minimum number of colors possible.
OBJECTIVES: The main objective of the study is While keeping the constraint that no two neighbouring vertices have the same colour, the goal is to reduce the number of colours needed to colour a graph's vertices. It further investigate how various techniques impact the execution time as the number of nodes in the graph increases.
METHODS: In this paper, we propose a novel method of implementing a Genetic Algorithm (GA) to address the GCP.
RESULTS: When the solution is implemented on a highly specified Google Cloud instance, we likewise see a significant increase in performance. The parallel execution on Google Cloud shows significantly faster execution times than both the serial implementation and the parallel execution on a local workstation. This exemplifies the benefits of cloud computing for computational heavy jobs like GCP.
CONCLUSION: This study illustrates that a promising solution to the Graph Coloring Problem is provided by Genetic Algorithms. Although the GA-based approach does not provide an optimal result, it frequently produces excellent approximations in a reasonable length of time for a variety of real-world situations.

Published: March 2024

This paper presents an effective technique and approach to deal with the dual challenges of performance optimization and privacy protection in microgrid power trading systems (MPTS) by utilizing attribute encryption technology. By embedding advanced cryptographic techniques into the operational substrate of microgrids, we introduce a novel approach to dramatically enhance the efficiency of energy distribution, while guaranteeing the privacy protection and integrity of participant data. The core objective of this technique is the application of attribute-based encryption (ABE), a method that offers fine-grained access control, ensuring sensitive information is made available only to eligible users based on their attributes, rather than their identities. In doing so, it meets the important requirement of securing data, without impairing the overall productivity of a power trading system. This paper presents a novel technique of ABE in the domain of MPTS, but also quantifies, through extensive theoretical analysis and simulations, how this integration leads to superior energy resource allocation and lower operational costs.
Association of autoimmune thyroid disease with type 1 diabetes mellitus and its ultrasonic diagnosis and management
Authors: Wang Jin , Wan Ke , Chang Xin , Mao Rui-Feng
Published: March 2024

As a common hyperglycemic disease, type 1 diabetes mellitus (T1DM) is a complicated disorder that requires a lifelong insulin supply due to the immune-mediated destruction of pancreatic β cells. Although it is an organ-specific autoimmune disorder, T1DM is often associated with multiple other autoimmune disorders. The most prevalent concomitant autoimmune disorder occurring in T1DM is autoimmune thyroid disease (AITD), which mainly exhibits two extremes of phenotypes: hyperthyroidism [Graves' disease (GD)] and hypo-thyroidism [Hashimoto's thyroiditis, (HT)]. However, the presence of comorbid AITD may negatively affect metabolic management in T1DM patients and thereby may increase the risk for potential diabetes-related complications. Thus, routine screening of thyroid function has been recommended when T1DM is diagnosed. Here, first, we summarize current knowledge regarding the etiology and pathogenesis mechanisms of both diseases. Subsequently, an updated review of the association between T1DM and AITD is offered. Finally, we provide a relatively detailed review focusing on the application of thyroid ultrasonography in diagnosing and managing HT and GD, suggesting its critical role in the timely and accurate diagnosis of AITD in T1DM.

Authors: Yi Yan , Wang Tao , Xu Wei , Zhang San-Hong
Published: March 2024

Gestational diabetes mellitus (GDM) is a pregnancy-related complication characterized by abnormal glucose metabolism in pregnant women and has an important impact on fetal development. As a bridge between the mother and the fetus, the placenta has nutrient transport functions, endocrine functions, etc. , and can regulate placental nutrient transport and fetal growth and development according to maternal metabolic status. Only by means of placental transmission can changes in maternal hyperglycemia affect the fetus. There are many reports on the placental pathophysiological changes associated with GDM, the impacts of GDM on the growth and development of offspring, and the prevalence of GDM in offspring after birth. Placental epigenetic changes in GDM are involved in the programming of fetal development and are involved in the pathogenesis of later chronic diseases. This paper summarizes the effects of changes in placental nutrient transport function and hormone secretion levels due to maternal hyperglycemia and hyperinsulinemia on the development of offspring as well as the participation of changes in placental epigenetic modifications due to maternal hyperglycemia in intrauterine fetal programming to promote a comprehensive understanding of the impacts of placental epigenetic modifications on the development of offspring from patients with GDM.

Published: March 2024

BACKGROUND

Patients with diabetes mellitus (DM) are predisposed to an increased risk of infection signifying the importance of vaccination to protect against its potentially severe complications. The Centers for Disease Control and Prevention/Advisory Committee on Immunization Practices (CDC/ACIP) issued immunization re-commendations to protect this patient population.

AIM

To assess the adherence of patients with DM to the CDC/ACIP immunization recommendations in Saudi Arabia and to identify the factors associated with the vaccine adherence rate.

METHODS

An observational retrospective study conducted in 2023 was used to collect data on the vaccination records from 13 diabetes care centers in Saudi Arabia with 1000 eligible patients in phase I with data collected through chart review and 709 patients in phase II through online survey.

RESULTS

Among participants, 10.01% (n = 71) had never received any vaccine, while 85.89% (n = 609) received at least one dose of the coronavirus disease 2019 (COVID-19) vaccine, and 34.83% (n = 247) had received the annual influenza vaccine. Only 2.96% (n = 21), 2.11% (n = 15), and 1.12% (n = 8) received herpes zoster, tetanus, diphtheria, and pertussis (Tdap), and human papillomavirus (HPV) vaccines, respectively. For patients with DM in Saudi Arabia, the rate of vaccination for annual influenza and COVID-19 vaccines was higher compared to other vaccinations such as herpes zoster, Tdap, pneumococcal, and HPV. Factors such as vaccine recommendations provided by family physicians or specialists, site of care, income level, DM-related hospitalization history, residency site, hemoglobin A1c (HbA1c) level, and health sector type can significantly influence the vaccination rate in patients with DM. Among non-vaccinated patients with DM, the most reported barriers were lack of knowledge and fear of side effects. This signifies the need for large-scale research in this area to identify additional factors that might facilitate adherence to CDC/ACIP vaccine recommendations in patients with DM.

CONCLUSION

In Saudi Arabia, patients with DM showed higher vaccination rates for annual influenza and COVID-19 vaccines compared to other vaccinations such as herpes zoster, Tdap, pneumococcal, and HPV. Factors such as vaccine recommendations provided by family physicians or specialists, the site of care, income level, DM-related hospitalization history, residency site, HbA1c level, and health sector type can significantly influence the vaccination rate in patients with DM.

BACKGROUND

The association of single nucleotide polymorphism of KCNQ1 gene rs2237895 with type 2 diabetes mellitus (T2DM) is currently controversial. It is unknown whether this association can be gene realized across different populations.

AIM

To determine the association of KCNQ1 rs2237895 with T2DM and provide reliable evidence for genetic susceptibility to T2DM.

METHODS

We searched PubMed, Embase, Web of Science, Cochrane Library, Medline, Baidu Academic, China National Knowledge Infrastructure, China Biomedical Liter-ature Database, and Wanfang to investigate the association between KCNQ1 gene rs2237895 and the risk of T2DM up to January 12, 2022. Review Manager 5.4 was used to analyze the association of the KCNQ1 gene rs2237895 polymorphism with T2DM and to evaluate the publication bias of the selected literature.

RESULTS

Twelve case–control studies (including 11273 cases and 11654 controls) met our inclusion criteria. In the full population, allelic model [odds ratio (OR): 1.19; 95% confidence interval (95%CI): 1.09–1.29; P < 0.0001], recessive model (OR: 1.20; 95%CI: 1.11–1.29; P < 0.0001), dominant model (OR: 1.27. 95%CI: 1.14–1.42; P < 0.0001), and codominant model (OR: 1.36; 95%CI: 1.15–1.60; P = 0.0003) (OR: 1.22; 95%CI: 1.10–1.36; P = 0.0002) indicated that the KCNQ1 gene rs2237895 polymorphism was significantly correlated with susceptibility to T2DM. In stratified analysis, this association was confirmed in Asian populations: allelic model (OR: 1.25; 95%CI: 1.13–1.37; P < 0.0001), recessive model (OR: 1.29; 95%CI: 1.11–1.49; P = 0.0007), dominant model (OR: 1.35; 95%CI: 1.20–1.52; P < 0.0001), codominant model (OR: 1.49; 95%CI: 1.22–1.81; P < 0.0001) (OR: 1.26; 95%CI: 1.16–1.36; P < 0.0001). In non-Asian populations, this association was not significant: Allelic model (OR: 1.06, 95%CI: 0.98–1.14; P = 0.12), recessive model (OR: 1.04; 95%CI: 0.75–1.42; P = 0.83), dominant model (OR: 1.06; 95%CI: 0.98–1.15; P = 0.15), codominant model (OR: 1.08; 95%CI: 0.82–1.42; P = 0.60. OR: 1.15; 95%CI: 0.95–1.39; P = 0.14).

CONCLUSION

KCNQ1 gene rs2237895 was significantly associated with susceptibility to T2DM in an Asian population. Carriers of the C allele had a higher risk of T2DM. This association was not significant in non-Asian populations.

Authors: Suparman Suparman
Published: March 2024

Security has become a significant issue in international relations because it involves aspects of territorial protection, peacekeeping, economic stability, and other elements that influence the lives of countries worldwide. In international relations, security involves a deep understanding of threats, conflicts, and strategies to maintain peace and stability at regional and global levels. This research aims to analyze state behavior in the context of security cooperation, focusing on the UK's participation in the AUKUS security alliance formed in 2021. The UK's decision to join AUKUS was driven by two main factors, namely national role conceptions and role prescriptions. This research pays special attention to the uniqueness of Britain's participation in this alliance, considering its geographical position in the North Atlantic region, not in the Indo-Pacific region, which is the main focus of AUKUS. This analysis will provide valuable insight for the Indonesian Government in addressing security dynamics in the Indo-Pacific region related to forming the AUKUS alliance. By understanding the motivational factors driving UK participation, this research can contribute to formulating more effective policies addressing regional and global security challenges.

Authors: Kelly Louise A
Published: March 2024

Background: The prevalence of obesity is extremely high and increasing in elementary school children in the US, but recent systematic reviews have concluded that there are no simple, generalizable and successful obesity prevention strategies available.

Objective: To assess whether an 8-week-school-based physical activity intervention would reduce BMI percentiles and improve physical fitness in both normal weight and obese children.

Material and Methods: One hundred and one children were consented to the study (mean age 8.12 ± 0.10 years). BMI and BMI percentiles for age and gender were determined using EpiInfo. Participants were classified as Obese (OB) (n=48) if they had a BMI percentile of ≥ 95% for their age and gender. Normal weight (NW) was (n=53) classified as having a BMI percentile lower than 75% for age and gender. Intervention consisted of an 8-week enhanced physical activity program in school (100 minutes/week). Physical fitness was assessed using the FITNESSGRAM test battery. Repeated measures GLM was used to assess within and between subjects’ effects from pre- to post-testing.

Results: GLM showed significant results within subject and between subject for BMI percentile, trunk lifts, push-ups, sit ups, sit and reach and the 1-mile run (p’s <0.01). However, our results also showed that there was a significant reduction in BMI percentile (0.001), weight (p=0.05) and waist/hip ratio (p=0.01) for the obese group.

Conclusion: Our study demonstrated that an 8-week physical activity intervention was successful in improving physical fitness in NW and OB children. The 8-week program also was successful in reducing BMI percentile in the OB group. Future studies should consider increasing both the duration of the program and the sample size.

We are now in the era of the digital world. Many industries have switched to digital technology such as photos, videos, music, and so on. Of course, this change brings many benefits for us in terms of speed and data access. The ease of accessing the internet also has a major impact on human life. The ease of accessing documents online is very helpful if you want to find and download pdf documents online. With this convenience, many of the same pdf files are downloaded more than once. This will definitely burden the storage space. To distinguish one pdf file from another, it is done by viewing and reading the contents of the pdf file. This is very inconvenient and time consuming. To overcome this, we need a practical way that can be used to search for the same pdf document so that it can delete duplicate pdf files. One way that can be used to overcome this problem is to use a hash function, one of the hash functions in cryptography is the MD 2 algorithm or Message Digest 2. By using the hash function, the identity of the pdf file can be generated. If the pdf files are the same it will produce the same hash value as well. This will make it easier to group the same pdf documents so that it will speed up the process of deleting the same pdf files. With the pdf file scanner application, pdf files will be searched for all folders and will group pdf files based on the same hash value. So that it will be easier for users to delete the same pdf file.

Text files have a large size that affects the storage space and the sending process. This size is a factor in how much storage space will be used and how long it will take to send files. The longer the text, the bigger the size. large size can be overcome by doing the compression process. Compression is done to reduce the size of a file. Compression algorithms that can be used are sequitur algorithm and punctured elias code algorithm. The advantage of the sequitur algorithm is that it replaces 2 characters side by side with 1 terminal character in the character set, while the advantage of the punctured elias code algorithm is that there are two codes, namely P1 and P2. Text file compression is done by reading the input string in the text file (*txt and *.doc) and encoding the string using punctured elias code P1 and P2. The two algorithms will be combined to produce a smaller size than the previous size.

Published: March 2024

Workpieces resulting from 3D printing manufacturing which were initially only for rapid prototyping purposes, are now used for final products. In its development, a method is needed that can accommodate the creation of multi-material structures because there are complex structures that require hard materials and elastic materials in one part at once. Multi-material manufacturing with a laminate structure in DLP 3D printing can be done by changing the resin material periodically as needed. One important aspect in multi-material 3D printing manufacturing is dimensional accuracy. In this research, the accuracy of multi-material specimen layer thickness from DLP 3D printer manufacturing was studied. The specimens were manufactured with a uniform CAD design, but with varying numbers of material layer pairs. The thickness of each layer of the specimen is measured. From the measurement results, it is known that there is an error in the thickness of each specimen due to the bottom layer phenomenon and the influence of the penetration range of UV light in the DLP 3D printing technique due to differences in the color density of the resin material and the concentration of the photoinitiator.

Published: March 2024

Silica scaling is the main problem that arises in the operation of geothermal power plants (PLTP) in Dieng. Silica scaling can disrupt electricity production and cause a buildup of waste in the environment. Silica scaling has a high silica (SiO2) content so it has the potential to be used as a value-added material, namely nanosilica. One method to obtain nanosilica is alkali fusion. This research aims to obtain nanosilica from silica scaling waste from PLTP Dieng using the alkali fusion method as well as knowing the characteristics of the nanosilica produced. The alkali fusion process is carried out using NaOH as an alkali source. Then mixing silica scaling powder and NaOH at varying temperatures of 600°C, 650°C and 700°C to produce nanosilica. The resulting nanosilica was then characterized to confirm the success of the synthesis process in producing nanosilica particles. The characterization carried out included x-ray diffraction (XRD) to characterize crystallinity, Fourier transform infrared (FTIR) to characterize functional groups, transmission electron microscope (TEM) and particle size analyzer (PSA) to determine particle size. The results of this research showed that amorphous nanosilica was successfully synthesized from silica scaling using the NaOH alkali fusion method. It was found from the results of TEM and PSA characterization that the smallest particle size was produced at a fusion temperature of 650°C. Furthermore, FTIR data also confirms the existence of functional groups at wave numbers identical to silica.

This study examined the relationship between the costs of environmental conservation and sustainable business growth of publicly traded Nigerian oil and gas companies. The study’s major objectives were to determine how the independent variables of environmental conservation represented by community development cost, pollution cost and environmental remediation cost affected the dependent variables of sustainable business growth represented by return on asset and gross margin return on investment. Data for the study came from financial statements and annual reports covering the years 2011–2022, and it employed an ex post facto research design. Regression analysis in E-View 10.0 was used to test the hypotheses. According to the empirical data analysis, there is a positive and statistically significant relationship between community development costs, and gross margin returns on investment (0.526033 and 0.000918), which implies that there is a significant relationship between the gross margin return on investment and sustainable business growth. Similarly, 2.652824 and 0.000000 indicate a favorable and statistically significant relationship between pollution cost and GMRI. However, -0.233125 and 0.000000 demonstrate a negative and statistically significant relationship between environmental remediation costs and GMRI. A total of three independent factors accounts for 53% of the variance in the dependent variable, according to the R-squared value of 0.534613. According to the study’s conclusions, there is a positive correlation between the costs of environmental conservation and the sustainable growth of listed oil and gas companies in Nigeria. The study also suggests that oil and gas companies should maintain a friendly environment for this will reduce the amount spent in repairing the damaged that their activities had caused on the environment. The goal of this initiative is to boost the efficiency of community development groups by providing incentives for their work on the created friendly environment.
