Authors: Babarinde Gbenga Festus , Abdulmajeed Idera Tajudeen , Gidigbi Matthew Oladapo
Published: August 2024

Purpose—This paper examines the impact of various environmental factors on the performance of banks in Nigeria. Specifically, the study analyzes how exchange rates, GDP growth, government expenditures, and interest rates influence the performance of selected Deposit Money Banks (DMBs) in Nigeria.
Design/methodology/approach—The study uses annual data sourced from the Central Bank of Nigeria (CBN) Statistical Bulletin and the annual reports and accounts of 12 randomly selected DMBs for the period from 2009 to 2018. The Panel Generalized Method of Moments (GMM) approach is employed to estimate the relationships between environmental factors and bank performance.
Findings — The research finds that GDP growth, interest rates, and government expenditure all have a positive and significant impact on the performance of banks. Among these factors, government expenditure has the most substantial effect on the earnings per share (EPS) of the selected banks.
Practical implications — Based on the findings, it is recommended that banks should manage their interest rates creatively within legal constraints to enhance performance. Banks should also pay close attention to government fiscal policies, especially expenditures, and incorporate these into their strategic decision-making. Additionally, banks are encouraged to develop policies, products, and services that support economic growth in Nigeria, potentially through development finance initiatives.
Originality/value—This study uses a robust panel data approach to provide valuable insights into how environmental factors affect bank performance in Nigeria. By highlighting the significant role of government expenditures and other factors, it offers practical recommendations for banks to improve their performance and align their strategies with macroeconomic conditions. This research contributes to understanding banking performance in emerging economies, particularly within the context of Nigeria.

Published: August 2024

Purpose—This research examines how compensation and work motivation impact employee performance at the Secretariat of the Provincial Legislative Council's Representative Board of East Java Province. Additionally, it explores the role of leadership style as a moderating factor in these relationships.
Design/methodology/approach — The study employs moderated regression analysis to assess the relationships between compensation, work motivation, and employee performance, with leadership style as a moderating variable. The sampling technique used is saturated sampling, involving all 163 population members as respondents to ensure comprehensive data collection and analysis.
Findings — The research findings indicate that both compensation and work motivation positively and significantly affect employee performance. However, the moderating effect of leadership style on the relationships between compensation and employee performance and between work motivation and employee performance was found to be weak.
Practical implications — Organizations should continue to focus on improving compensation and work motivation strategies to enhance employee performance. While leadership style may not significantly moderate these relationships in this context, it remains essential for creating a supportive work environment. Further investigation into different leadership styles or additional factors might provide more insights into strengthening the moderating effect.
Originality/value — This study provides valuable insights into the impact of compensation and work motivation on employee performance in a specific governmental context. It also contributes to understanding the role of leadership style as a moderating variable, highlighting areas for future research and practical applications in managing employee performance.

Authors: Shierly Sephiani  , Syafitri Wildan
Published: August 2024

One type of potential tax is income tax. Indonesia has many MSMEs and contributes to 61.97% of national GDP. However, the contribution of MSMEs to the tax sector is not comparable to the tax revenue. The lack of awareness among MSME taxpayers is one of factors for the low level of tax compliance, which has a domino effect on the amount of tax revenue. The Government’s regulation as a response to the problem is through the implementation of PP 23/2018. The Government reduced tax rate from 1% to 0.5% would to make it easier for MSMEs and increase tax compliance. The domino effect will strengthen the role of MSMEs as a biggest source for the Indonesian economy, including increasing tax revenue. The research was conducted in Tangerang City to describe how far the effect of changes in PPh rates has on MSME taxpayer compliance and tax revenue in a city with the title of “Kota Seribu Industri”. The method used is quantitative descriptive analysis. The results of this study that the reduction in tariffs increases the number of taxpayers, which also has implications for increasing tax compliance. But on the contrary, the realization of tax revenue actually decreased.

Marine plastic debris that enters the sea can be fragmented by physical and chemical factors, then float in the water column or accumulate in sediments, which have the potential to be ingested by marine biota, causing digestive system disorders, fecundity, eating capacity, reproduction, and death. This study aimed to identify the accumulation of microplastics in water and sediments in Outer Ambon Bay using a purposive sampling method and descriptive analysis for data related to microplastics' type, color, and size, as well as follow-up tests of the least significant difference. The results show that the waters of Outer Ambon Bay have been polluted by microplastics. The number of microplastic particles found in water samples at three different depths (0, 50, and 100 cm) was 201 particles L-1, and in sediment samples, it was 325 particles g-1. It is supported by the fact that the type of fiber has a thin shape and size and can float on the surface of the water and by the existence of beaches where there are fishing activities, boat ports, rivers, and densely populated areas, as well as sandy and muddy sediments that can trap more microplastics during the tidal period. Therefore, it is necessary to prevent the waste problem in the waters of Ambon Bay. Keywords: Identification, Marine Pollution, Microplastics, Outer Ambon Bay.

The restoration of mercury-contaminated sites is a global concern, and countless studies have been conducted to formulate the best remediation practice. Mercury pollution in Indonesia has been a national issue. Thus, the government has enforced the reduction and elimination of this toxic and persistent chemical element and its compounds since 2019. As claimed to be the most environmentally friendly and cost-efficient technique, bioremediation using indigenous bacteria offers excellent potential to be implemented in developing countries such as Indonesia. This study is a preliminary part of four-year research at formulating a bioremediation technique to restore mercury-contaminated soils, especially in agricultural areas. In this investigation, fifteen indigenous bacterial isolates were tested for their resistance to mercury using two different techniques: the agar plate method, namely the disk-diffusion technique, and a modified version of the cup-plate technique. Inhibitory zone diameter (IZD) was measured and compared using Bland-Altman analysis between two techniques with supplementation of HgCl2 2-100 ppm range to the Mueller-Hinton agar media. The disk-diffusion technique appeared to give inconsistent measurements of IZD along the increase of HgCl2 concentration, in which the highest IZD mean was obtained from samples with 8 and 10 ppm HgCl2. Meanwhile, the cup-plate technique shows a lower average of IZD compared to the disk-diffusion technique. This report provides insights on the resistance of potential bacteria for mercury bioremediation. Further study should consider the accuracy of the agar plate method to test the bacterial resistance to any particular compound. Keywords: bioremediation, cup-plate, disk-diffusion, inhibitory zone diameter, method accuracy.

Authors: Naimark Jody , Tinetti Mary E , Delbanco Tom , Dong Zhiyong , Harcourt Kendall , Esterson Jessica , Charpentier Peter , Walker Jan
Published: August 2024

Background

Persons with multiple chronic conditions face complex medical regimens and clinicians may not focus on what matters most to these patients who vary widely in their health priorities. Patient Priorities Care is a facilitator-led process designed to identify patients’ priorities and align decision-making and care, but the need for a facilitator has limited its widespread adoption.

Objective

The aims of this study are to design and test mechanisms for patients to complete a self-directed process for identifying priorities and providing their priorities to clinicians.

Methods

The study involved patients of at least 65 years of age at 2 family medicine practices with 5 physicians each. We first tested 2 versions of an interactive website and asked patients to bring their results to their visit. We then tested an Epic previsit questionnaire derived from the website’s questions and included standard previsit materials. We completed postintervention phone interviews and an online survey with participating patients and collected informal feedback and conducted a focus group with participating physicians.

Results

In the test of the first website version, 17.3% (35/202) of invited patients went to the website, 11.4% (23/202) completed all of the questions, 2.5% (5/202) brought results to their visits, and the median session time was 43.0 (IQR 28.0) minutes. Patients expressed confusion about bringing results to the visit. After clarifying that issue in the second version, 15.1% (32/212) of patients went to the website, 14.6% (31/212) completed the questions, 1.9% (4/212) brought results to the visit, and the median session time was 35.0 (IQR 35.0) minutes. In the test of the Epic questionnaire, 26.4% (198/750) of patients completed the questionnaire before at least 1 visit, and the median completion time was 14.0 (IQR 23.0) minutes. The 8 main questions were answered 62.9% (129/205) to 95.6% (196/205) of the time. Patients who completed questionnaires were younger than those who did not (72.3 vs 76.1 years) and were more likely to complete at least 1 of their other assigned questionnaires (99.5%, 197/198) than those who did not (10.3%, 57/552). A total of 140 of 198 (70.7%) patients responded to a survey, and 86 remembered completing the questionnaire; 78 (90.7%) did not remember having difficulty answering the questions and 57 (68.7%) agreed or somewhat agreed that it helped them and their clinicians to understand their priorities. Doctors noted that the sickest patients did not complete the questionnaire and that the discussion provided a good segue into end-of-life care.

Conclusions

Embedding questionnaires assaying patient priorities into patient portals holds promise for expanding access to priorities-concordant care.
Data Analytics to Support Policy Making for Noncommunicable Diseases: Scoping Review
Authors: Dritsakis Giorgos , Gallos Ioannis , Psomiadi Maria-Elisavet , Amditis Angelos , Dionysiou Dimitra
Published: August 2024

Background

There is an emerging need for evidence-based approaches harnessing large amounts of health care data and novel technologies (such as artificial intelligence) to optimize public health policy making.

Objective

The aim of this review was to explore the data analytics tools designed specifically for policy making in noncommunicable diseases (NCDs) and their implementation.

Methods

A scoping review was conducted after searching the PubMed and IEEE databases for articles published in the last 10 years.

Results

Nine articles that presented 7 data analytics tools designed to inform policy making for NCDs were reviewed. The tools incorporated descriptive and predictive analytics. Some tools were designed to include recommendations for decision support, but no pilot studies applying prescriptive analytics have been published. The tools were piloted with various conditions, with cancer being the least studied condition. Implementation of the tools included use cases, pilots, or evaluation workshops that involved policy makers. However, our findings demonstrate very limited real-world use of analytics by policy makers, which is in line with previous studies.

Conclusions

Despite the availability of tools designed for different purposes and conditions, data analytics is not widely used to support policy making for NCDs. However, the review demonstrates the value and potential use of data analytics to support policy making. Based on the findings, we make suggestions for researchers developing digital tools to support public health policy making. The findings will also serve as input for the European Union–funded research project ONCODIR developing a policy analytics dashboard for the prevention of colorectal cancer as part of an integrated platform.
Estimating Adverse Events Associated With Herbal Medicines Using Pharmacovigilance Databases: Systematic Review and Meta-Analysis
Authors: Kongkaew Chuenjid , Phan Dang Thuc Anh , Janusorn Prathan , Mongkhon Pajaree
Published: August 2024

Background

Herbal medicines (HMs) are extensively used by consumers/patients worldwide. However, their safety profiles are often poorly reported and characterized. Previous studies have documented adverse events (AEs) associated with HMs, such as hepatotoxicity, renal failure, and allergic reactions. However, the prevalence rate of AEs related to HMs has been reported to be low. To date, no systematic review and meta-analysis has comprehensively analyzed the AEs of HMs using published data acquired from pharmacovigilance (PV) databases.

Objective

This study aimed to (1) estimate the reporting rate of the AEs of HMs using PV databases and (2) assess the detailed data provided in AE reports.

Methods

In this systematic review and meta-analysis, MEDLINE/PubMed, SCOPUS, EMBASE, and CINAHL were systematically searched for relevant studies (until December 2023). The DerSimonian-Laird random effects model was used for pooling the data, and subgroup analyses, the meta-regression model, and sensitivity analysis were used to explore the source of heterogeneity. Crombie’s checklist was used to evaluate the risk of bias (ROB) of the included studies.

Results

In total, 26 studies met the eligibility criteria. The reporting rate of the AEs of HMs ranged considerably, from 0.03% to 29.84%, with a median overall pooled estimate of 1.42% (IQR 1.12%-1.72%). Subgroup analyses combined with the meta-regression model revealed that the reporting rate of the AEs of HMs was associated with the source of the reporter (P=.01). None of the included studies provided full details of suspected herbal products, only the main ingredients were disclosed, and other potentially harmful components were not listed.

Conclusions

This systematic review and meta-analysis highlighted risks related to HMs, with a wide range of reporting rates, depending on the source of the reporter. Continuous efforts are necessary to standardize consumer reporting systems in terms of the reporting form, education, and follow-up strategy to improve data quality assurance, aiming to enhance the reliability and utility of PV data for monitoring the safety of HMs. Achieving effective monitoring and reporting of these AEs necessitates collaborative efforts from diverse stakeholders, including patients/consumers, manufacturers, physicians, complementary practitioners, sellers/distributors, and health authorities.

The role of microbial wound contamination in chronic pain development in patients with injuries
Authors: Ksenchyna K.V. , Ksenchyn O.O. , Nazarchuk O.A. , Dmytriiev D.V.
Published: August 2024

Nowadays, with the start of hostilities in Ukraine, the number of people with injuries has increased and continues to grow. Of course, one of the main issues facing by medical professionals is preventing complications and restoring sufficient functional capacity. Pain is one of the protective mechanisms of the human body; its prolonged course is one of the most important causes for reducing the quality of life and limiting a person’s work capacity. Acute pain is positioned as the body’s main signal for help, usually as a disease symptom, while chronic pain can be an independent nosological unit and mostly appears after primary cause. Secondary chronic pain is one of the injury consequences that can occur and significantly worsen the patient’s prognosis and reduce quality of life. Prevention of the secondary chronic pain is possible if all prerequisites are known. Furthermore, the human body interacts with a complex community of bacteria, fungi, and viruses. Several microorganisms create the microbiome of the skin, which ensures its barrier function and plays an important role in the immune response in wounds. These processes are not always predictable, and both positive and negative effects on wound healing can be observed. After all, the duration of wound healing directly depends on the type of microorganisms and their sensitivity to the antibiotic treatment. The long process of wound surface healing can lead more likely to a violation of all physiological processes in this body part. This can be quite an important factor in chronic pain occurrence.

In today’s world of accessible knowledge education, knowledge-based short videos have become a favored learning tool for many learners. However, the effectiveness of this learning method remains unclear, and research in the field of short video learning is still in its early stages and needs further exploration. This study surveyed 202 university students and conducted case analyses on 4 students to investigate the effects of self-determined motivation, goal orientation, self-regulated learning strategies, and cognitive academic achievements in the context of learning through knowledge-based short videos. The results indicate that students who use short videos for learning demonstrate a moderate level of self-determined motivation, while their goal orientation, self-regulated learning strategies, and cognitive academic achievements require improvement. Senior students exhibited better self-determined motivation and cognitive academic achievements compared to junior students. Additionally, an increase in self-determined motivation, self-regulated learning strategies, and cognitive academic achievements was observed with increased time spent watching short videos. It was found that a moderate viewing time of about 2 hours per day is associated with certain learning benefits, while excessive viewing time may result in the opposite effect. Based on these findings, the study concludes with learning recommendations aimed at optimizing the application of short video learning tools and providing insights for future research in this area.

Objective: To investigate the gastroprotective influence of 2,3-Dichloro-6-(trifluoromethoxy) quinoxaline in a rat model of indomethacininducedgastric ulcers.
Methods: Thirty male Wistar rats were randomly divided into five groups (n = 6) as follows: Group 1 (control), Group 2 (indomethacin only, 30 mg/kg), Group 3 (indomethacin and 2,3-Dichloro-6-(trifluoromethoxy) quinoxaline, 30 mg/kg), Group 4 (indomethacin with 2,3-Dichloro-6-(trifluoromethoxy) quinoxaline, 60 mg/kg), and Group 5 (indomethacin with esomeprazole, 30 mg/kg). The efficacy of 2,3-Dichloro-6-(trifluoromethoxy) quinoxaline in mitigating gastric ulcers induced by indomethacin in rats was evaluated based on gastric morphology, histopathology, and inflammatory biomarkers.
Results: Indomethacin-induced stomach ulcers resulted in epithelial damage and blood streaks on the gastric mucosa. However, treatmentwith indomethacin and 2,3-Dichloro-6-(trifluoromethoxy) quinoxaline (60 mg/kg) significantly (P < 0.05) reduced ulcers compared to the indomethacin-only group. Inflammatory cells were observed in the indomethacin group, while the 60 mg/kg 2,3-Dichloro-6- (trifluoromethoxy) quinoxaline-treated group exhibited the restoration of normal epithelial tissue and minimal inflammatory cells, similar to the control and esomeprazole-treated groups. Furthermore, 2,3-Dichloro-6-(trifluoromethoxy) quinoxaline significantly decreased inflammatory biomarkers (TNF-α, IL-6, INF-γ, and IL-β1) and increased gastroprotective mediator levels (PGE2 and mucin), both with P-values below 0.05, in contrast to the effects of indomethacin.
Conclusion: This study provides clinical evidence highlighting the gastroprotective properties of 2,3-Dichloro-6-(trifluoromethoxy) quinoxaline. Its initial application reveals, for the first time, its efficacy in treating gastric ulcers induced by indomethacin. However, further tests are warranted to validate these findings.
