Authors: Prakasita Vinsa Cantya , Ilham Jessika , Amarantini Charis
Published: August 2024

Demam tifoid merupakan penyakit infeksi yang disebabkan oleh Salmonella typhi yang menyerang sistem pencernaan. Infeksi Salmonella ini menyebabkan morbiditas dan mortalitas yang signifikan di seluruh dunia. Penyakit ini dapat diatasi dengan antibiotik, namun saat ini sudah banyak terjadi resistensi antibiotik sehingga penggunaannya kurang efektif. Temulawak merupakan salah satu tanaman yang digunakan sebagai obat tradisional di Indonesia yang memiliki banyak manfaat kesehatan. Bacteriocin memiliki aktivitas antimikroba terhadap bakteri patogen. Oleh karena itu, penelitian ini bertujuan untuk mengetahui aktivitas daya hambat ekstrak etanol temulawak dan bakteriosin Bifidobacterium longum terhadap pertumbuhan S. typhi. Ekstraksi temulawak dilakukan dengan metode maserasi dengan pelarut etanol. Skrining fitokimia dengan berbagai reagen dilakukan untuk mengetahui senyawa yang ada di dalamnya. Kadar total fenolik diukur dengan menggunakan persamaan regresi yang dibandingkan dengan asam galat. Bakteriosin B. longum diperoleh dengan cara menambahkan NaOH pada supernatan hasil panen dan memanaskannya pada suhu tinggi. Uji aktivitas daya hambat ekstrak etanol temulawak (EET) dan bakteriosin B. longum (BBl) dilakukan dengan metode difusi disk. EET mengandung alkaloid, saponin, terpenoid, flavonoid, dan fenol dengan kadar total fenol 30,73 ± 2,81 mg GEA/g. EET memiliki aktivitas daya hambat yang rendah hingga sedang, sedangkan BBl memiliki aktivitas daya hambat yang rendah terhadap S. typhi.

Published: August 2024

The study examines the influence of market orientation on the performance of mobile operators in the telecommunication industry and the moderating effect of strategic marketing on the relationship. Based on a cross-sectional survey of 286 management staff of the four largest mobile operators in Nigeria (MTN, Glo, 9Mobile, Airtel), an empirical evidence was established. The data were analyzed using descriptive statistics and Structural Equation Modeling (SEM). The SEM outlined the connection between the dimensions of market orientation and organizational performance. The findings revealed that inter-functional coordination (β = 0.485, t = 2.542, p = 0.013 < 0.05) and customer orientation (β = 0.245, t = 2.043, p = 0.038 < 0.05) significantly influence organizational performance, while competitor orientation (β = 0.159, t = 1.870, p = 0.065 < 0.05) has no discernible effect. It was also found that strategic marketing has a major impact on organizational performance (β = 0.466, t = 4.175, p = 0.000 < 0.05), but it has no moderating influence on the relationship between market orientation and organizational performance (β = 0.032, t = 0.445, p = 0.665 > 0.05). This implies that strategic marketing has a direct effect on organizational performance and not a moderating effect. Therefore, the study recommends that market orientation especially customer orientation and inter-functional coordination, as well as strategic marketing, should become a culture in the telecommunication industry.
Factors affecting corporate cash holdings: Evidence from the energy sector of Saudi Arabia
Authors: Fatima Nadeem
Published: August 2024

This study investigates the impact of firm-specific components of cash holdings on the cash reserves of energy firms. Decisions related to cash management are significant and treated as confident made by financial managers to increase the value of a firm. Therefore, financial managers are obligated to hold an optimum level of cash to enhance the firm value. The study depends on secondary data from seven energy firms listed on the Saudi Arabian Stock Exchange over the period between 2014 and 2023. The study considers cash holdings as a dependent variable, leverage, networking capital, and profitability as explanatory variables, and firm size as a control variable. The study employed a linear regression model and a generalized linear regression (GLM) model with Gaussian and Gamma distributions to analyze the data. The results show that Saudi Arabian energy firms reserve approximately 7% of cash, while external financing is 51%. The pooled regression results show that the association between leverage and firms’ cash reserves was negative (–0.064) and significant at less than a 1% significance level. Further, the networking capital and profitability were positively related (0.063 and 0.113) and significant at 5% and 1% significance levels. Moreover, the firm size was positive but insignificant. The generalized linear regression model results with Gaussian and Gamma distributions were similar to the simple linear regression with minor variation.

Methods used to determine pesticide residues in teas typically require several laborious steps for sample preparation before analysis. In this study, a simple method based on solid-liquid extraction with low-temperature partitioning (SLE/LTP) and analysis by gas chromatography coupled to mass spectrometry (GC-MS) was optimized and validated for the determination of pesticide residues (pirimiphos-methyl, flutriafol, cyproconazole, and bifenthrin) in dehydrated green tea leaves. After low-temperature partitioning (LTP), the extract in acetonitrile was subjected to a clean-up step using primary secondary amine (PSA) and octadecylsilane (C18) as sorbents for chlorophyll removal. The optimized SLE/LTP-GC-MS method was validated, and it proved to be effective and selective for extracting pesticides from green tea samples, presenting limit of detection (LOD) and limit of quantification (LOQ) of 0.015 and 0.050 mg kg-1, respectively. Recovery ranged between 81-111%, coefficients of variation were less than 16% and coefficients of determination (R2 ) were greater than 0.990. The optimized and validated method was applied to green tea and 13 other tea varieties sampled in South and Southeast regions of Brazil. The pesticides under study were detected in some of those samples at values higher than the maximum residue limits (MRLs) allowed by the European Union.

Every organization definitely needs a leader to condition an activity to run effectively. An organization looks good when a leader brings positive things and conversely an organization looks bad when a leader brings negative things. The aim of this research is to describe leadership management from the perspective of the Koran. In this article the researcher uses the literature method, namely collecting several references related to titles such as books, journals and articles. Researchers also use a qualitative descriptive approach, namely a research approach that refers to aspects of opinion or ways of social understanding of society in general. The results of the research reveal that there are many verses in the Koran that discuss leadership management, so before the rise of leadership in the world of education or an Islamic organization, it was already discussed in the Koran, which used words such as: caliph, imam, and ulil amri. in accordance with the concept of leadership in Islam. Even in discussing Islamic education management, it will still be related to POAC (planning, organizing, actuating, and controlling) which is a management function.
Humanity as a tool of the Word: The beginning of monothelite disputes and Aristotle’s interpretation in the 6th century
Authors:   Sociological Institute, Federal Center of Theoretical and Applied Sociology, Russian Academy of Sciences, Shchukin Timur A.
Published: August 2024

The article examines the Christology of Theodore of Tharan, one of the first Monothelite theologians, in the context of philosophical teachings relevant to this time. An analysis of the surviving fragments from Theodore’s epistles shows that his writings contain four concepts that mark him as a follower of the peripatetic philosophical tradition: the source of movement for the soul-body composite is that which is beyond it; the soul is one in the sense that the vegetable, animal and rational souls constitute a single essence and their action is one; the soul is the instrument of the Word, and the body is the instrument of the soul; it is impossible for a mover to move when the mover (the source of its movement) is stationary. It is assumed that Theodore of Tharan hardly borrowed these concepts directly from Aristotle, dealing with either peripatetic or neoplatonic interpretations of the Stagirite. It is concluded that Theodore of Tharan sympathized with a point of view close to authentic Aristotelianism in the interpretation of Alexander of Aphrodisias — this is indicated by the closeness of his views to the latter’s teaching about the active mind, about the unity of the soul, about the relationship of the movable and the moving. However, the instrumentalism of Theodore of Tharan, referring rather to the Neoplatonic in terpretation of Aristotle, indicates that there is no complete identity with the views of Alexander of Aphrodisias in his texts.
Unlocking urban blue-green infrastructure: an interdisciplinary literature review analysing co-benefits and synergies between bio-physical and socio-cultural outcomes
Authors: McNabb Tyler , Charters Frances J. , Challies Edward , Dionisio Rita
Published: August 2024

Conventional methods of urbanization and risk management have exposed communities to multiple climatic, ecological, and social vulnerabilities. Urban blue-green infrastructure (BGI) refers to a range of nature-based approaches to mitigating the impacts of hazards and enhancing the connections between natural and social capitals, with a particular focus on the presence and management of water elements. However, the bio-physical benefits of BGI are often prioritized over a wider range of potential social-ecological co-benefits. This article draws on a narrative literature review to present the bio-physical and socio-cultural co-benefits of urban BGI, and to examine the relationships, synergies, and trade-offs between these. This review identifies a wide range of socio-cultural and bio-physical benefits of blue-green stormwater infrastructure, including improved mental and physical wellbeing, enhanced cultural connections and values, strengthened social cohesion and sense of place, amelioration of urban heat island effects, reduction of flood risks, improved water quality, and enhanced biodiversity. A number of environmental and socio-cultural trade-offs were identified between these co-benefits, however, including the presence of negatively viewed insects and plant-produced allergens. Aimed at expanding knowledge on the effective implementation of urban BGI to achieve such outcomes, this review highlights wider co-benefits and relationships between them.

Sleep quality and anxiety are closely related. Those who have difficulty sleeping often have problems with anxiety, and vice versa, those who have difficulty often experience problems sleeping. Sleep quality has a significant effect on anxiety and is influenced by, among others, the type of work, physical activity, physical exercise, and sports. This study aims to determine the relationship between exercise body performance, sleep quality, and anxiety. This research is descriptive research with a survey method. Using purposive sampling with certain criteria. Participants are members of Studio Primadonna. Instruments with online questionnaires: the Pittsburgh Sleep Quality Index (PSQI) for sleep quality and the Generalized Anxiety Disorder-7 questionnaire were used to assess anxiety. Statistical analysis using chi-square. The survey results show that on average Primadonna studio members have quite good sleep quality, as evidenced by PSQI data 16 people (80%) have quite good sleep quality and have minimal anxiety, as evidenced by the results of GAD-7 data as many as 10 people (50%) ) has a minimal anxiety category. Subjects in the moderately good category on average had minimal anxiety and exercised 5 times a week, while subjects in the moderately poor category on average had mild anxiety and exercised 3 times a week It can be concluded that body performance exercise has a good influence on the sleep quality and anxiety of body performance exercise members at Studio Primadonna. The more often and consistently participants do body performance exercises, the anxiety decreases and the quality of sleep improves. Conversely, the less often you exercise, anxiety increases and sleep quality worsens. Future research is expected to be able to link sleep quality, anxiety, and other relevant variables, with varying subjects and views from various perspectives.

Authors: Simbolon Demsa , Oktavia Riska , Krisnasary Arie
Published: August 2024

An athlete needs to pay attention to the amounts of nutrients that give the body energy. If an athlete doesn't know much about proper nutrition, it can make them less aware of how important it is to eat healthy food. Indonesian athletes who aren't performing well are doing so because they aren't getting enough healthy nutrition. This is because their teachers don't know how nutrition can help athletes perform better. The study aimed at investigating the relationship between nutritional knowledge and macronutrient intake with the nutritional status of athletes. Analytic descriptive research with a cross sectional approach. There were 94 athletes as the population, and a sample of 63 athletes in the dormitory involved, through simple random sampling method. The instruments used were the respondent's identity, nutritional knowledge questionnaire, 3x24 hour food recall, height measurement using microtoice and weight using digital scales, then the analysis of the data was conducted with 3 stages, namely univariate, bivariate analysis with chi square test and multivariate analysis with linear regression test. The results identified a relationship between nutritional knowledge (p=0.012) and macronutrient intake, namely energy intake (p=0.029), protein intake (p=0.001) with the nutritional status of athletes. Nevertheless, the study findings revealed no significant relation between fat consumption (p=0.781) and carbohydrate intake (p=0.927) and the nutritional condition of athletes. The most influential factor on nutritional status is energy intake. The greater the amount of energy intake, the greater the tendency to have more nutritional status. Therefore, it is crucial to implement the nutrition education to athletes in relation with nutritional intake and feeding based on balanced nutrition menu guidelines according to the needs of athletes.

The Dual Task Ball Balancing Test and Its Association With Cognitive Function: Algorithm Development and Validation
Authors: Greene Barry , Tobyne Sean , Jannati Ali , McManus Killian , Gomes Osman Joyce , Banks Russell , Kher Ranjit , Showalter John , Bates David , Pascual-Leone Alvaro
Published: August 2024

Background

Dual task paradigms are thought to offer a quantitative means to assess cognitive reserve and the brain’s capacity to allocate resources in the face of competing cognitive demands. The most common dual task paradigms examine the interplay between gait or balance control and cognitive function. However, gait and balance tasks can be physically challenging for older adults and may pose a risk of falls.

Objective

We introduce a novel, digital dual-task assessment that combines a motor-control task (the “ball balancing” test), which challenges an individual to maintain a virtual ball within a designated zone, with a concurrent cognitive task (the backward digit span task [BDST]).

Methods

The task was administered on a touchscreen tablet, performance was measured using the inertial sensors embedded in the tablet, conducted under both single- and dual-task conditions. The clinical use of the task was evaluated on a sample of 375 older adult participants (n=210 female; aged 73.0, SD 6.5 years).

Results

All older adults, including those with mild cognitive impairment (MCI) and Alzheimer disease–related dementia (ADRD), and those with poor balance and gait problems due to diabetes, osteoarthritis, peripheral neuropathy, and other causes, were able to complete the task comfortably and safely while seated. As expected, task performance significantly decreased under dual task conditions compared to single task conditions. We show that performance was significantly associated with cognitive impairment; significant differences were found among healthy participants, those with MCI, and those with ADRD. Task results were significantly associated with functional impairment, independent of diagnosis, degree of cognitive impairment (as indicated by the Mini Mental State Examination [MMSE] score), and age. Finally, we found that cognitive status could be classified with >70% accuracy using a range of classifier models trained on 3 different cognitive function outcome variables (consensus clinical judgment, Rey Auditory Verbal Learning Test [RAVLT], and MMSE).

Conclusions

Our results suggest that the dual task ball balancing test could be used as a digital cognitive assessment of cognitive reserve. The portability, simplicity, and intuitiveness of the task suggest that it may be suitable for unsupervised home assessment of cognitive function.
Characteristics of Existing Online Patient Navigation Interventions: Scoping Review
Authors: Marsh Meghan , Shah Syeda Rafia , Munce Sarah E P , Perrier Laure , Lee Tin-Suet Joan , Colella Tracey J F , Kokorelias Kristina Marie
Published: August 2024

Background

Patient navigation interventions (PNIs) can provide personalized support and promote appropriate coordination or continuation of health and social care services. Online PNIs have demonstrated excellent potential for improving patient knowledge, transition readiness, self-efficacy, and use of services. However, the characteristics (ie, intervention type, mode of delivery, duration, frequency, outcomes and outcome measures, underlying theories or mechanisms of change of the intervention, and impact) of existing online PNIs to support the health and social needs of individuals with illness remain unclear.

Objective

This scoping review of the existing literature aims to identify the characteristics of existing online PNIs reported in the literature.

Methods

A scoping review based on the guidelines outlined in the Joanna Briggs Institute framework was conducted. A search for peer-reviewed literature published between 1989 and 2022 on online PNIs was conducted using MEDLINE, CINAHL, Embase, PsycInfo, and Cochrane Library databases. Two independent reviewers conducted 2 levels of screening. Data abstraction was conducted to outline key study characteristics (eg, study design, population, and intervention characteristics). The data were analyzed using descriptive statistics and qualitative content analysis.

Results

A total of 100 studies met the inclusion criteria. Our findings indicate that a variety of study designs are used to describe and evaluate online PNIs, with literature being published between 2003 and 2022 in Western countries. Of these studies, 39 (39%) studies were randomized controlled trials. In addition, we noticed an increase in reported online PNIs since 2019. The majority of studies involved White females with a diagnosis of cancer and a lack of participants aged 70 years or older was observed. Most online PNIs provide support through navigation, self-management and lifestyle changes, counseling, coaching, education, or a combination of support. Variation was noted in terms of mode of delivery, duration, and frequency. Only a small number of studies described theoretical frameworks or change mechanisms to guide intervention.

Conclusions

To our knowledge, this is the first review to comprehensively synthesize the existing literature on online PNIs, by focusing on the characteristics of interventions and studies in this area. Inconsistency in reporting the country of publication, population characteristics, duration and frequency of interventions, and a lack of the use of underlying theories and working mechanisms to inform intervention development, provide guidance for the reporting of future online PNIs.
The Feasibility and Acceptability of Using a Digital Conversational Agent (Chatbot) for Delivering Parenting Interventions: Systematic Review
Authors: Klapow Max C , Rosenblatt Andrew , Lachman Jamie , Gardner Frances
Published: August 2024

Background

Parenting interventions are crucial for promoting family well-being, reducing violence against children, and improving child development outcomes; however, scaling these programs remains a challenge. Prior reviews have characterized the feasibility, acceptability, and effectiveness of other more robust forms of digital parenting interventions (eg, via the web, mobile apps, and videoconferencing). Recently, chatbot technology has emerged as a possible mode for adapting and delivering parenting programs to larger populations (eg, Parenting for Lifelong Health, Incredible Years, and Triple P Parenting).

Objective

This study aims to review the evidence of using chatbots to deliver parenting interventions and assess the feasibility of implementation, acceptability of these interventions, and preliminary outcomes.

Methods

This review conducted a comprehensive search of databases, including Web of Science, MEDLINE, Scopus, ProQuest, and Cochrane Central Register of Controlled Trials. Cochrane Handbook for Systematic Review of Interventions and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were used to conduct the search. Eligible studies targeted parents of children aged 0 to 18 years; used chatbots via digital platforms, such as the internet, mobile apps, or SMS text messaging; and targeted improving family well-being through parenting. Implementation measures, acceptability, and any reported preliminary measures of effectiveness were included.

Results

Of the 1766 initial results, 10 studies met the inclusion criteria. The included studies, primarily conducted in high-income countries (8/10, 80%), demonstrated a high mean retention rate (72.8%) and reported high acceptability (10/10, 100%). However, significant heterogeneity in interventions, measurement methods, and study quality necessitate cautious interpretation. Reporting bias, lack of clarity in the operationalization of engagement measures, and platform limitations were identified as limiting factors in interpreting findings.

Conclusions

This is the first study to review the implementation feasibility and acceptability of chatbots for delivering parenting programs. While preliminary evidence suggests that chatbots can be used to deliver parenting programs, further research, standardization of reporting, and scaling up of effectiveness testing are critical to harness the full benefits of chatbots for promoting family well-being.

Published: August 2024

Background

Our prototype smoking cessation chatbot, Quin, provides evidence-based, personalized support delivered via a smartphone app to help people quit smoking. We developed Quin using a multiphase program of co-design research, part of which included focus group evaluation of Quin among stakeholders prior to clinical testing.

Objective

This study aimed to gather and compare feedback on the user experience of the Quin prototype from end users and smoking cessation professionals (SCPs) via a beta testing process to inform ongoing chatbot iterations and refinements.

Methods

Following active and passive recruitment, we conducted web-based focus groups with SCPs and end users from Queensland, Australia. Participants tested the app for 1-2 weeks prior to focus group discussion and could also log conversation feedback within the app. Focus groups of SCPs were completed first to review the breadth and accuracy of information, and feedback was prioritized and implemented as major updates using Agile processes prior to end user focus groups. We categorized logged in-app feedback using content analysis and thematically analyzed focus group transcripts.

Results

In total, 6 focus groups were completed between August 2022 and June 2023; 3 for SCPs (n=9 participants) and 3 for end users (n=7 participants). Four SCPs had previously smoked, and most end users currently smoked cigarettes (n=5), and 2 had quit smoking. The mean duration of focus groups was 58 (SD 10.9; range 46-74) minutes. We identified four major themes from focus group feedback: (1) conversation design, (2) functionality, (3) relationality and anthropomorphism, and (4) role as a smoking cessation support tool. In response to SCPs’ feedback, we made two major updates to Quin between cohorts: (1) improvements to conversation flow and (2) addition of the “Moments of Crisis” conversation tree. Participant feedback also informed 17 recommendations for future smoking cessation chatbot developments.

Conclusions

Feedback from end users and SCPs highlighted the importance of chatbot functionality, as this underpinned Quin’s conversation design and relationality. The ready accessibility of accurate cessation information and impartial support that Quin provided was recognized as a key benefit for end users, the latter of which contributed to a feeling of accountability to the chatbot. Findings will inform the ongoing development of a mature prototype for clinical testing.
Performance of Digital Cognitive Assessment in Predicting Dementia Stages Delineated by Dementia Severity Rating Scale: Retrospective Study (Preprint)

BACKGROUND

Dementia is characterized by impairments in an individual’s cognitive and functional abilities. Digital cognitive assessments have been shown to be effective in detecting mild cognitive impairment and dementia but whether they can stage the disease remains to be studied.

OBJECTIVE

In this study, we examined: (1) the correlation between scores obtained from BC-Assess, a digital cognitive assessment, and scores obtained from the Dementia Severity Rating Scale (DSRS), and (2) the accuracy of using the BC-Assess score to predict dementia stage delineated by the DSRS score. We also explored whether BC-Assess can be combined with information from the Katz Index of Independence in Activities of Daily Living (ADL) to obtain enhanced accuracy.

METHODS

Retrospective analysis was performed on a BrainCheck dataset containing 1,751 dementia patients with different cognitive and functional assessments completed for cognitive care planning, including the DSRS, the ADL, and the BC-Assess. The patients were staged according to their DSRS total score (DSRS-TS): 982 mild (DSRS-TS: 10-18), 656 moderate (19-26), and 113 severe (37-54) patients. Pearson correlation was used to assess the associations between BC-Assess overall score (BC-OS), ADL total score (ADL-TS), and DSRS-TS. Logistic regression was used to evaluate the possibility of using patients’ BC-OS and ADL-TS to predict their stage.

RESULTS

We find moderate Pearson correlations between DSRS-TS and BC-OS (r = -.53), between DSRS-TS and ADL-TS (r = -.55), and a weak correlation between BC-OS and ADL-TS (r = .37). Both BC-OS and ADL-TS significantly decrease with increasing severity. BC-OS demonstrates to be a good predictor of dementia stages, with area under the ROC curve (ROC-AUC) of classification using logistic regression ranging from .733 to .917. When BC-Assess is combined with ADL, higher prediction accuracies are achieved, with ROC-AUC ranging from .786 to .961.

CONCLUSIONS

Our results suggest that BC-Assess could serve as an effective alternative tool to DSRS for grading dementia severity, particularly in cases where DSRS, or other global assessments, may be challenging to obtain due to logistical and time constraints.

Colorectal cancer is the second leading cause of death among all cancer cases worldwide. Cancer cells often exhibit overexpression of cyclooxygenase-2 (COX-2), producing prostaglandin E2 (PEG2) and subsequent inflammation and neoplasia. Moringa oleifera is rich in bioactive compounds such as polyphenols, flavonoids, and saponins, known for their anti-inflammatory and antioxidant properties. This study aimed to investigate the inhibitory effects of M. oleifera leaves ethanol extract on COX-2 expression in HT-29 cells. Dried M. oleifera leaves (5 g) were ethanol-macerated for 24 hours, yielding a 10 mg ethanol extract. MTT inhibition is used for immunocytochemistry evaluation of COX-2 expression. Molecular docking of phenolic compounds from the extract on PPARγ indicated an agonistic potential. The ethanol extract of M. oleifera leaves demonstrated anticancer activity with an IC50 value of 114.8 µg/ml, with a significant reduction in COX-2 expression observed at a dose of 100 ppm, resulting in an H-score of 111.83 ± 2.21. Peroxisome proliferator-activated receptor-gamma (PPARγ) activity is thought to be the first step in suppressing COX-2 expression. Three phenolic compounds found in M. oleifera are predicted to be PPARγ agonists: rutin, naringin, and hesperidin, according to the molecular docking simulations.
