Authors: Yıldız Rıdvan , Özden Ali Veysel
Published: April 2024

Purpose: This study aims to investigate the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on key parameters, including nerve conduction velocity, grip strength, pain, and upper extremity functionality in individuals with carpal tunnel syndrome (CTS).
Methods: The study involved 51 patients (90 hands) diagnosed with carpal tunnel syndrome, comprising 12 males and 39 females, ranging in age from 18 to 58 years. Participants were divided into groups by random randomization method. Sensory branch conduction velocity of the median nerve was assessed via electromyography (EMG), hand grip strength was measured using a digital dynamometer, and pain intensity was quantified with a visual analog scale (VAS); additionally, upper extremity functionality was evaluated using the Upper Extremity Functional Index (UEFI) scale before and after the treatment. In the experimental group, in addition to the conventional physiotherapy program, 10 sessions of auricular vagus nerve stimulation were administered; for the sham and control groups, the conventional physiotherapy program alone was conducted over the course of 10 sessions.
Results: The analysis revealed no statistically significant differences between the groups concerning variables such as body mass index (BMI), age, gender, educational background, and smoking status (p>0.05). However, within-group evaluations exhibited significant differences compared to baseline values in terms of nerve conduction velocity, pain perception, and upper extremity functionality, with no such difference observed in grip strength (p

Published: April 2024

Background

Since fall 2020, mobile health (mHealth) apps have become an integral part of the German health care system. The belief that mHealth apps have the potential to make the health care system more efficient, close gaps in care, and improve the economic outcomes related to health is unwavering and already partially confirmed. Nevertheless, problems and barriers in the context of mHealth apps usually remain unconsidered.

Objective

The focus groups and interviews conducted in this study aim to shed light on problems and barriers in the context of mHealth apps from the perspective of patients.

Methods

Guided focus groups and individual interviews were conducted with patients with a disease for which an approved mHealth app was available at the time of the interviews. Participants were recruited via self-help groups. The interviews were recorded, transcribed, and subjected to a qualitative content analysis. The content analysis was based on 10 problem categories (“validity,” “usability,” “technology,” “use and adherence,” “data privacy and security,” “patient-physician relationship,” “knowledge and skills,” “individuality,” “implementation,” and “costs”) identified in a previously conducted scoping review. Participants were asked to fill out an additional questionnaire about their sociodemographic data and about their use of technology.

Results

A total of 38 patients were interviewed in 5 focus groups (3 onsite and 2 web-based) and 5 individual web-based interviews. The additional questionnaire was completed by 32 of the participants. Patients presented with a variety of different diseases, such as arthrosis, tinnitus, depression, or lung cancer. Overall, 16% (5/32) of the participants had already been prescribed an app. During the interviews, all 10 problem categories were discussed and considered important by patients. A myriad of problem manifestations could be identified for each category. This study shows that there are relevant problems and barriers in the context of mHealth apps from the perspective of patients, which warrant further attention.

Conclusions

There are essentially 3 different areas of problems in the context of mHealth apps that could be addressed to improve care: quality of the respective mHealth app, its integration into health care, and the expandable digital literacy of patients.

Published: April 2024

Background

Individuals from minoritized racial and ethnic backgrounds experience pernicious and pervasive health disparities that have emerged, in part, from clinician bias.

Objective

We used a natural language processing approach to examine whether linguistic markers in electronic health record (EHR) notes differ based on the race and ethnicity of the patient. To validate this methodological approach, we also assessed the extent to which clinicians perceive linguistic markers to be indicative of bias.

Methods

In this cross-sectional study, we extracted EHR notes for patients who were aged 18 years or older; had more than 5 years of diabetes diagnosis codes; and received care between 2006 and 2014 from family physicians, general internists, or endocrinologists practicing in an urban, academic network of clinics. The race and ethnicity of patients were defined as White non-Hispanic, Black non-Hispanic, or Hispanic or Latino. We hypothesized that Sentiment Analysis and Social Cognition Engine (SEANCE) components (ie, negative adjectives, positive adjectives, joy words, fear and disgust words, politics words, respect words, trust verbs, and well-being words) and mean word count would be indicators of bias if racial differences emerged. We performed linear mixed effects analyses to examine the relationship between the outcomes of interest (the SEANCE components and word count) and patient race and ethnicity, controlling for patient age. To validate this approach, we asked clinicians to indicate the extent to which they thought variation in the use of SEANCE language domains for different racial and ethnic groups was reflective of bias in EHR notes.

Results

We examined EHR notes (n=12,905) of Black non-Hispanic, White non-Hispanic, and Hispanic or Latino patients (n=1562), who were seen by 281 physicians. A total of 27 clinicians participated in the validation study. In terms of bias, participants rated negative adjectives as 8.63 (SD 2.06), fear and disgust words as 8.11 (SD 2.15), and positive adjectives as 7.93 (SD 2.46) on a scale of 1 to 10, with 10 being extremely indicative of bias. Notes for Black non-Hispanic patients contained significantly more negative adjectives (coefficient 0.07, SE 0.02) and significantly more fear and disgust words (coefficient 0.007, SE 0.002) than those for White non-Hispanic patients. The notes for Hispanic or Latino patients included significantly fewer positive adjectives (coefficient −0.02, SE 0.007), trust verbs (coefficient −0.009, SE 0.004), and joy words (coefficient −0.03, SE 0.01) than those for White non-Hispanic patients.

Conclusions

This approach may enable physicians and researchers to identify and mitigate bias in medical interactions, with the goal of reducing health disparities stemming from bias.

Published: April 2024

Background

Medical science has developed rapidly. One of them is ERAS (Enhanced Recovery After Surgery) which is a multidisciplinary team development pathway for perioperative methods that offer a variety of benefits. Some of the advantages of the ERAS method are speeding up the post-operative recovery period, economic benefits, and shortening the Length of Stay (LOS) by minimizing surgical stress so that the patient quickly returns to a normal physiological state.

Objective

This study aims to analyze the readiness of the team that will support the ERAS application at General Academic Hospital (RSUD) Dr Soetomo.

Methods

This is an observational analytic study with a cross-sectional design using a questionnaire. Patient baseline data were taken from the examination at the anesthesiology outpatient clinic. Assessment for patient understanding was carried out directly after a brief explanation of ERAS method by the researcher. The patient's level of understanding was assessed by two investigators and rated on a scale of 1 to 5. Primary data and assessment of understanding of doctors and medical personnel were filled in independently by research subjects on online forms and rated on a scale of 1 to 5. Data was collected from March 23 to April 14 2022, at RSUD Dr. Soetomo Surabaya. The analysis results are considered significant if the p-value is less than 0.05. The analysis was carried out using SPSS 19 software.

Results

Most patients planned to undergo surgery in the field of urology (82.9%), followed by caesarean section (14.6), and almost all patients or their families agreed to surgery using the ERAS method (95.1%). The medical team consists of 110 doctors from 4 areas of expertise, namely specialist doctors and residents in anesthesiology, urology surgery, obstetrics and gynecology, as well as orthopedics and traumatology. The health team consists of 56 personnel, namely anesthesiologists, surgeons, recovery room nurses, nutritionists and pharmacists. The majority (61%) of health workers had heard about ERAS and stated that ERAS was ready to be implemented at RSUD Dr. Soetomo (89%). Most doctors stated that ERAS was ready to be implemented at Dr. Soetomo and its human resources and facilities are considered qualified.

Conclusion

The ERAS method at RSUD Dr. Soetomo is considered quite ready to start, especially the Obsgyn study program, which is supposed to have an excellent level of understanding of ERAS and is enthusiastic to begin immediately. The patient group can be said to understand and accept the ERAS method well as a perioperative method for handling their cases.
HUBUNGAN RASIO BUN-ALBUMIN PLASMA TERHADAP MORTALITAS DAN LAMA RAWAT PASIEN COVID-19 DI RSUP DR. SARDJITO
Authors: Primastuti Githa Rizki
Published: April 2024

Latar Belakang: Peningkatan insidensi pandemi COVID-19 menyebabkan tingkat mortalitas dan lama rawat yang cukup tinggi pada negara berkembang. Deteksi dini diperlukan untuk menekan angka mortalitas. Metode deteksi dini dilaporkan, seperti RT-PCR, immunoassay, dan CT-scan, tetapi memerlukan biaya mahal. Peningkatan BUN dengan penurunan albumin adalah kondisi laboratorium yang dihasilkan oleh keadaan inflamasi tinggi, seperti COVID-19. Hubungan rasio BUN-Albumin plasma penderita pneumonia terbukti dalam memprediksi mortalitas dan lama rawat lebih kuat dibandingkan dengan parameter tunggal BUN atau albumin. Jika terbukti berhubungan, penanda ini menguntungkan karena dapat diakses secara luas, sederhana, dan ekonomis.

Tujuan: Mengetahui hubungan antara rasio BUN-Albumin plasma terhadap mortalitas dan lama rawat pasien COVID-19 di RSUP Dr. Sardjito.

Metode: Rancangan penelitian dengan metode studi observasional kohort retrospektif pasien terkonfirmasi COVID-19 di RSUP Dr. Sardjito. Data kadar BUN dan albumin plasma saat admisi dikumpulkan untuk menghitung cut-off optimal menggunakan kurva ROC. Hubungan antara kadar rasio BUN-Albumin dengan mortalitas dianalisis dengan metode chi-square test dilanjutkan dengan regresi logistik pada analisis multivariat. Analisis terhadap lama rawat inap

menggunakan analisis survival cox-regression dan dinyatakan signifikan apabila menghasilkan p < 0,05.

Hasil: Total subjek penelitian adalah 1650 pasien, dengan median usia 56 tahun. Nilai cut-off rasio BUN-Albumin dalam memprediksi mortalitas didapatkan 5,634, dengan sensitivitas 65,0% dan spesifisitas 63,7%. (AUC = 0,689; 95% CI 0,663-0,715; p=0,001). Analisis multivariat menunjukkan bahwa peningkatan rasio BUN-Albumin menjadi faktor yang independen dan signifikan sebagai prediktor mortalitas (OR 2,378; 95% CI 1,809 – 3,127) dan lama rawat pasien (HR 0,655; 95% CI 0,574 - 0,748; p<0,001). Usia, jenis kelamin, penggunaan oksigenasi tekanan positif, hipertensi, obesitas, PPOK, dan asma tidak secara independent berhubungan dengan mortalitas.

Kesimpulan: Peningkatan rasio BUN-Albumin secara independen dan signifikan berhubungan dengan peningkatan risiko mortalitas dan lama rawat inap pasien COVID-19.
Kinetics of β-2-Microglobulin with Hemodiafiltration and High-Flux Hemodialysis
Authors: Ward Richard A. , Daugirdas John T.
Published: April 2024

Key Points

Addition of hemodiafiltration has a relatively small impact on reducing either predialysis or time-averaged serum β-2-microglobulin levels.

Residual kidney function has a major impact on the predialysis and time-averaged serum β-2-microglobulin levels.

Background

A kinetic model for β-2-microglobulin removal and generation was used to explore the impact of adding hemodiafiltration on predialysis and time-averaged serum values.

Methods

The model was tested on data from the HEMO study and on a sample of patients undergoing high-flux hemodialysis. The impact of hemodiafiltration on β-2-microglobulin levels was evaluated by modeling four randomized studies of hemodiafiltration versus hemodialysis. The impact of residual kidney function on β-2-microglobulin was tested by comparing results of previously reported measured data with model predictions.

Results

In the low-flux and high-flux arms of the HEMO study, measured median β-2-microglobulin reduction ratios could be matched by dialyzer clearances of 5.9 and 29 ml/min, respectively. Median predialysis serum β-2-microglobulin levels were matched if generation rates of β-2-microglobulin were set to approximately 235 mg/d. In another group of patients treated with dialyzers with increased β-2-microglobulin clearances, measured cross-dialyzer clearances (57±28 ml/min) were used as inputs. In these studies, the kinetic model estimates of intradialysis and early postdialysis serum β-2-microglobulin levels were similar to median measured values. The model was able to estimate the changes in predialysis serum β-2-microglobulin in each of four published randomized comparisons of hemodiafiltration with hemodialysis, although the model predicted a greater decrease in predialysis serum β-2-microglobulin with hemodiafiltration than was reported in two of the studies. The predicted impact of residual kidney clearance on predialysis serum β-2-microglobulin concentrations was similar to that reported in one published observational study. Modeling predicted that postdilution hemodiafiltration using 25 L/4 hours replacement fluid would lower serum time-averaged concentration of β-2-microglobulin by about 18.2%, similar to the effect of 1.50 ml/min residual kidney GFR.

Conclusions

A two-pool kinetic model of β-2-microglobulin yielded values of reduction ratio and predialysis serum concentration that were consistent with measured values with various hemodiafiltration and hemodialysis treatment regimens.

Authors: Tomić Nenad , Todorović Violeta , Vasić Aleksandra S.
Published: April 2024

The effects of the EU-UK Withdrawal Agreement, reached on 17 October 2019, on the stocks listed on the London Stock Exchange are the subject of the paper. The classic event study methodology was used to quantify impact. This research is based on a sample of 138 stocks, divided into five sample sections according to the company’s business sector. In contrast to the research conducted after the referendum, which showed a clear negative impact on almost all of the observed sectors, the research conducted in this paper does not provide a unique conclusion. Three sectors recorded obvious positive effects, namely the financial sector, the food industry, and the medical sector, while no sector suffered obvious negative effects. The remaining two sectors did not provide data to aid in reaching a clear conclusion, as there were positive, negative and statistically insignificant results across different tests.
THE IMPACT OF ECONOMIC TRENDS ON BANK PROFITABILITY – THE CASE OF SERBIA AND CROATIA
Authors: Lekpek Ahmedin , Šabotić Zenaida
Published: April 2024

This paper analyses the direction and intensity of the impact of economic trends on the profitability of banks in Serbia and Croatia in the period between the years 2006 and 2021. This paper aims to determine which indicators of economic trends have the most substantial impact on the profitability of banks in the selected countries. As key indicators of economic trends, GDP per capita, the GDP growth rate, inflation rate, real interest rate, broad money growth, general government final consumption expenditure, current account balance, gross savings, trade, and unemployment are selected as independent variables. At the same time, bank profitability was measured with bank return on equity, in percentages (ROE), and bank return on assets, in percentages (ROA) – two indicators which represent the dependent variables selected for this research. Descriptive analysis, mean difference, correlation, and univariate and multivariate regression were used in the research. Research results show that changes in real interest rates and unemployment have a significant impact on the profitability of banks in both of the selected countries, while changes in GDP per capita growth have a statistically significant effect only in Serbia, and general government final consumption expenditure has a statistically significant impact only in Croatia. The influence of other indicators of economic trends is not statistically significant.

Authors: Gadžić Aleksandar , Vučković Igor
Published: April 2024

Active commuting is considered one of the many forms of physical activity that could increase the level of physical activity among school children. The aim of the current study was to examine the differences between the health-related fitness of school children who engage in active and passive commuting to school, and to explore the associations between active commuting to school and the health-related physical fitness of school children. A total of 152 children (58 girls and 94 boys), aged 12, from four primary schools in the Kraljevo area participated in this study. Basic anthropometric measures were taken along with eight physical fitness tests. Boys who actively commute had greater upper body muscular endurance and cardiorespiratory fitness, and girls who were active school commuters had better results in flexibility, explosive power, upper body muscular endurance, and cardiorespiratory fitness. Linear regression analysis revealed significant associations between active commuting, and abdominal strength and cardiorespiratory fitness for boys, and flexibility and upper body muscular endurance for girls. Considering these positive findings, it is recommended that future studies be conducted on a larger sample and that they include intensive educational campaigning to encourage Serbian schoolchildren to practice active commuting to and from school is likewise recommended.

Published: April 2024

In sport psychology, coping with challenges is critical to the success and well-being of athletes. Self-efficacy, as one of the most important features of successful athletes, plays a significant role in designing their training and development programmes. The goal of this exploratory research was to examine and determine whether and how coping strategies for stressful situations can be used as predictors of the psychological factor of self-efficacy in adolescent athletes. The total sample of participants in this study consists of 167 adolescent athletes, that is, 90 boys and 77 girls. Variables in the research were operationalised using appropriate instruments. Statistical techniques for data processing used in this research were the Pearson correlation coefficient and multiple regression. The most important findings of the study include a statistically significant model that can explain 28.6% of the variance for the criterion in the sample of respondents. Task- and emotion-oriented coping mechanisms were identified as statistically significant predictors. Self-efficacy was higher in athletes with higher task orientation, and lower in those with emotion orientation.
Impulsividad y obesidad: una relación multidimensional
Authors: Guillén Riebeling Raquel del Socorro
Published: April 2024

Las causas de la obesidad son multifactoriales que van desde la genética, la biología, pasando por las ciencias sociales, la psicológica hasta las disciplinas que contribuyen en su explicación desde su campo conceptual como la astronomía. Para algunas aproximaciones psicológicas de la obesidad señalan que es el resultado del comer en exceso de la persona. Este comer excesivo a su vez se explica por la falta de control de impulsos, respuestas compulsivas, desenfreno o voracidad. De aquí que el propósito de la psicoterapia sea: brindar habilidades para manejar diversas señales de alimentación excesiva y corregir errores en el régimen dietético y de actividad física (Torres et al., 2011). Responder ante una situación provocadora tiene su estilo: de manera inmediata, casi refleja, se puede catalogar de forma impulsiva, por sus componentes cognoscitivos, primero “el hacerlo sin pensar”, segundo valorar la acción y darse cuenta de ello. Generando componentes emocionales: el darse cuenta acciona el remordimiento, la vergüenza o la culpa. Y la ausencia de reacción emocional o emoción plana. Esta particularidad de comportamiento ha sido abordada por la psicología y etiquetada como: activación, conducta no reflexiva, impulsiva, sin control o mal adaptativa. 
El propósito del presente trabajo fue identificar la relación de la obesidad con la impulsividad, esta última considerada como impulsos generados por el individuo a través de procesos psicológicos como la conducta, cogniciones, emociones, personalidad, neurológicos y psicopatologías con vinculación con la alimentación y otras variables socio-psicológicas, reportadas en publicaciones científicas. Las conclusiones muestran la multi-dimensionalidad de su relación y las consideraciones para la atención en salud.

Authors: Maheswari Sunku Uma
Published: April 2024

Abstract: Resources are getting limited with the increasing population. The incessant drive to meet food demands compels farmers to augment crop production using both natural and artificial means, including chemical fertilizers and pesticides. While these substances safeguard crops against pests and fungi, their excessive use compromises food quality and poses health risks due to their infiltration into the food chain. Recognizing this issue, there is a pressing need for a portable device capable of analyzing the organic composition of edibles. This study endeavors to ascertain both organic and inorganic elements present in food items, empowering consumers to make informed choices about their consumption. Central to this research is the development of an electronic device utilizing infrared technology to detect chemical residues. By displaying the ratio of organic to inorganic components, consumers can utilize this data as a guideline for selecting safe-to-consume food products,here we are proposed a portable device which makes it easy to identify whether the fruit is organic or inorganic based on this consumer can conclude what to eat and what should not eat.
India’s Foreign Policy Towards Pakistan: 2019-2024
Authors: Gupta Anurag
Published: April 2024

Abstract: India's foreign policy towards Pakistan from 2019 to 2024 was characterized by a nuanced approach that balanced diplomatic engagement with assertive measures to address security concerns. India consistently emphasized the need for Pakistan to take concrete action against cross-border terrorism and terrorist infrastructure. This approach was evident in various diplomatic initiatives, such as the Kartarpur Corridor, aimed at fostering dialogue and people-to-people contacts. However, progress towards meaningful reconciliation was hindered by persistent tensions, particularly regarding the status of Jammu and Kashmir. India's decision to revoke Jammu and Kashmir's special autonomous status in August 2019 further escalated tensions with Pakistan.Despite occasional offers for dialogue, including during multilateral forums, progress remained limited due to Pakistan's continued support for terrorist groups and cross-border infiltration. India also pursued a policy of international isolation against Pakistan, highlighting its role in sponsoring terrorism and seeking support from major global powers to pressurize Pakistan into taking decisive action against terrorist organizations. Overall, India's foreign policy towards Pakistan during this period aimed to balance the imperatives of national security and regional stability while exploring opportunities for dialogue and cooperation.

Published: April 2024

The Fuegian snipe Gallinago stricklandii (Gray, 1845) is one of the most enigmatic members of the family Scolopacidae Rafinesque, 1815. It is the least known species of the Gallinago genus and inhabits throughout the range of the biome of South American temperate forests, between the Maule region (36°S) and Cape Horn (56°S). In this biogeographical range, its reproductive and migratory habits are still poorly known. In this study, we report observations conducted between the years 2002 and 2023 in the Cape Horn National Park, with an emphasis on the most recent fieldwork on Horn Island. On this island, between January and October 2023, we recorded the autoecology of a family group composed of two adults and one juvenile. One of these adults was captured, banded, and measured in February 2023 (55°57.896’S - 67°13.478’W). The family group of G. stricklandii on Horn Island resided there during the summer, fall, winter, and spring seasons. This behavior contrasts with the migratory habit of the Magellanic snipe G. magellanica (King 1828), a better-known sympatric species. In addition to the resident habits of this family group and other individuals of G. stricklandii, we report new information about the morphology, feeding, and reproductive habits in the southern end of its distribution. This information recorded at the southern extreme of the American continent will enable new studies about this species and open up comparative analyses with other species of the cosmopolitan Scolopacidae family, which includes the world’s northernmost breeding birds at the boreal extreme of the Americas

LAPLACIAN-BASED BLUR DETECTION ALGORITHM FOR DIGITAL BREAST TOMOSYNTHESIS IMAGES IN IMPROVING BREAST CANCER DETECTION
Authors: Harron Nur Athiqah , Sulaiman Siti Noraini , Osman Muhammad Khusairi , A. Karim Noor Khairiah , Isa Iza Sazanita
Published: April 2024

The most challenging aspect of working with digital images captured in an uncontrolled environment is to determine whether the image is of sufficient quality to be studied further. One of the most frequent reasons for a decrease in the quality of digital images is the presence of blur artefacts, especially when the images are taken from various angles of the x-ray source with limited angular range such as in digital breast tomosynthesis (DBT). The unwanted artefacts might substantially obscure the breast cancer location, especially in extremely dense fibroglandular breast tissue. It is almost impossible to differentiate breast cancer lesions in blurry and lowcontrast DBT images, thereby reducing the accuracy of lesion diagnosis. Due to this blurry artefact issue, this study aims to assess the performance of Laplacian-based Blur Detection (LbBD) algorithm for the blurry detection of DBT images. The LbBD algorithm is designed and developed using MATLAB R2021a software. The algorithm identifies the amount of blurriness by calculating the image variance; the farther the variance is from the threshold value, the less blurry is the image. On the contrary, the lower the variance level is from the threshold value, the greater the blur level. An online survey was conducted with an expert to assess the quality of 20 DBT images using two subjective measurements of blur or non-blur to ascertain the algorithm's performance. Three threshold values were used to compare the outcome with the output of the algorithm's status. With a low error rate (0.05), an accuracy of 95% at the ideal threshold value of 200, and an image size reduction of 10%, the system successfully predicts blurry images.

Nanoparticles technology has gained a great deal of interest in medical and non-medical fields. Gold nanoparticles (AuNPs) which are one of the most attractive metal nanoparticles are widely used in many biomedical fields either for therapeutic or diagnostic purposes. The properties of AuNPs, such as their stability, high biocompatibility, large surface area, relatively inert element, and tunable chemical and physical characteristics have enabled a wide range of applications and discoveries. The AuNPs can be synthesised chemical, physical, or biological synthesis. It is prepared through top-down or bottom-up methods depending on the starting material preparation. AuNPs are used in assays to detect diagnostic markers and specific nucleic acid sequence. Additionally, it is also used in assays to improve bacterial species identification. This review article provides a general overview of the structures, properties, synthesis, and various innovative applications of AuNPs in laboratory medicine such as in chemical pathology, immunology, haematology, molecular, cytogenetics, and transfusion medicine laboratories.

Blood substitutes are substances used to replace or supplement the activities of biological blood cellular or acellular components. It is meant to be a transfusion-free option. There are four main categories that blood substitutes fall into: red blood cell substitutes, white blood cell substitutes, platelet substitutes, and plasma derivatives. Red blood cells (RBCs) substitutes can be divided into biological and chemical oxygen carriers. Biological oxygen carriers are haemoglobin-based oxygen carrier (HBOC) and stem cell derived red blood cells (cRBC). Sanguinate is the sole FDA-approved HBOC drug due to its sickle cell reversal, vasodilatory, and noninflammatory qualities while cRBC is utilized to produce universal group of RBCs. It has greater biological connections with natural bloods than chemical oxygen carriers, the second type of RBCs substitutes. When cRBC were transfused into participants, it was found that 63% of the cells continued to circulate in the blood, matching the half-life of a normal RBC, which is 28 days. These showed that red blood cells could be cultivated in a lab and that they also responded well in the human body. A study on stem cell derived red blood cells (cRBC) using growth stimulants, medium cultures, and genetic manipulation to immortalise human erythroid line has yielded mature RBCs. Now, this study is in the clinical trials which portrayed a huge success in the artificial blood field due to its immortal property. Perfluorocarbon (PFC) and polymer-based oxygen carriers are the two subcategories of chemical-based oxygen carriers. Products in this category may not be structurally resemble haemoglobin or RBCs, but they are intended to serve the primary physiological function of blood. Due to the complexity of the cellular parts of the immune system, no alternative to white blood cells (WBC) has been made artificially yet. However, immunotherapy strategies may offer the "functional substitution" for WBC especially in the case of artificial adaptive immunity. There have been approved alternatives for plasma derivatives but none to substitute platelets yet.

Published: April 2024

This study examines the operating expenses (OPEX) incurred by tankers and bulk carriers (bulkers), which are widely utilized vessels within the maritime sector, over the period from 2018 to 2021. The study specifically examines the movement of OPEX during the specified period and assesses the impact of the COVID-19 pandemic, vessel age, and size on OPEX. The study and comprehension of the behaviour of operating expenses hold significant importance for managerial purposes in shipping companies, as it is one of the two most critical expenses. The OPEX data is obtained from the Moore Maritime Index (MMI) database. The vessels are categorized into clusters based on age and size to facilitate a more focused and comprehensive analysis of OPEX. Data are examined through statistical analysis. The study’s findings suggest a positive correlation between OPEX and the age of vessels, with a stronger correlation observed in larger vessels. Furthermore, OPEX experienced a consistent increase throughout the entire study period, with the rate of increase directly linked to the vessel’s size. Ultimately, OPEX remained unaffected by the pandemic. This study is distinctive in that it examines not only the OPEX behaviour of different types of vessels but also considers vessel size subcategories and the impact of COVID-19.

The purpose of this study is to investigate the impact of the combination of the unified theory of acceptance and use of technology (UTAUT) and perceived variable costs on the use of the Indonesian Financial Accounting Standard (Standar Akuntansi Keuangan — SAK) Online application by accountants, auditors and academics. And also, to determine how Indonesian accountants work in collaboration with the Indonesian Accountants Association (Ikatan Akuntan Indonesia — IAI) by distributing online questionnaires to accountants, auditors, and academics who have used and/or continue to use the SAK Online application. Data were analyzed using partial least square structural equation modeling (PLS-SEM) and a quantitative data collection method. According to the findings of this study, behavioral intention and facilitating conditions have a significant impact on use behavior; whereas performance expectations, social influences, and perceived cost have a significant impact on behavioral intention. Other factors, such as effort expectation and the conducive environment, have no discernible effect on behavioral intention. The findings of this study can be used effectively by IAI as a developer to determine various strategies for increasing the number of SAK Online users, and by companies/agencies as users to determine strategies for maximizing the use of SAK Online by employees/members.

Published: April 2024

The study compares the CAMEL ratings of five central Indian commercial banks over 12 years (2011–2022). The findings indicate that most banks received a rating of 1, with an average capital adequacy ratio (CAR) of 15.18 percent. Maintaining low non-performing loan (NPL) rates is a priority for Indian banks, as reflected in the average of 1.98 percent with a grade of 2. The research concludes that these banks are well-managed, showcasing an average operational efficiency/income ratio of 40 percent (rated 3), signifying good managerial efficiency. This suggests banks can meet short-term customer commitments and withdrawals adequately. Notably, State Bank of India (SBI) and Punjab National Bank (PNB) received a grade of 2, while Axis Bank, Industrial Credit and Investment Corporation of India (ICICI) Bank, and Housing Development Finance Corporation (HDFC) Bank scored a rating of 1. The study indicates that private sector banks outperform their public sector counterparts across all CAMEL model parameters, showcasing more robust performance metrics. The paper advises Indian banks to invest in the long run, watch their risks, and aim for steady growth and profit. The study emphasises the importance of capital, assets, and management for a healthy banking system, suggesting improvements in earnings and liquidity management for overall stability and growth.

Authors: Kang Jen-Chun , Liang Chaoyun
Published: April 2024

In this study, we explored the determinants of the backfire effect by analysing supporters’ reactions to information propagated by the opposition camps. We focused on the topic of pork consumption. The study cohort (N = 971) comprised the supporters of the pan-blue (N = 422) and pan-green (N = 549) camps in Taiwan. Data were collected through an online survey. The echo chambers and message response emerged as robust factors influencing the backfire effect on individuals regardless of their political orientation. Message presentation negatively affected the induction of backfire effects. For the pan-green supporters, behavioural control and animal welfare attitude, respectively, exerted positive and negative influences on the induction of backfire effects. Our findings provide insights into the determinants of the backfire effect, a phenomenon wherein individuals fail to differentiate between fact and fiction despite receiving credible corrective information.
