Authors: Alshafei Atef , Zawam Entesar , Galal Mahmoud , Khan Anwar , El Saba Yaser , Hassan Moustafa
Published: September 2023

Objective:

This study aimed to investigate the validity of the mean platelet volume (MPV) alone and MPV combined with the revised Clinical Risk Index for Babies (CRIB II) score to predict neonatal mortality in preterm infants.

Materials and Methods:

This retrospective observational study performed between May 2018 and June 2021 included preterm neonates (gestational age 23–32 weeks) admitted to a tertiary neonatal intensive care unit (NICU) within 12 hours of birth, who were followed up until death or discharge. MPV was recorded at admission and within 72 hours before death or discharge. The CRIB II score variables were assessed within 12 hours of birth, and the area under the receiver operating characteristic curve (AUC) was calculated for the MPV and CRIB II scores to predict neonatal mortality.

Results:

We investigated 404 newborns, of whom 28 (6.9%) died. The mean neonatal gestational age was 28.6±2.8 weeks. The MPV was significantly higher in non-survivors than in survivors (p=0.001). The AUC for the MPV and the CRIB II score was 0.68 (95% CI: 0.55–0.80) and 0.85 (95% CI: 0.79–0.91), respectively. The AUC for the MPV combined with the CRIB II score was 0.91 (95% CI 0.87–0.95). The difference in MPV at birth between survivors and non-survivors was statistically non-significant.

Conclusion:

MPV was found to be a poorer predictor of neonatal mortality than the CRIB II score; however, MPV combined with the CRIB II score demonstrated significantly improved predictive ability for preterm infant mortality risk.

Published: September 2023

Introduction:

Extensively and multi-drug resistant isolates of bacteria (MDR, XDR) have caused significant
health problems and are responsible for high morbidity and mortality as well. In this critical condition,
the discovery, design, or development of new antibiotics is of great concern. According to this necessity, antimicrobial
peptides (AMPs) suggested as promising agents. Accordingly, this study aims to evaluate the GKY25
peptide to develop its future antibacterial applications as well as confirmation of LPS neutralization.

Methods:

Predictions of 3D structure and helical wheel projection analysis of the peptide were performed by ITASSER
and Heliquest servers. Binding affinity and antibacterial activity were performed using molecular
docking and CAMPR4, respectively, followed by experimental binding assay as well as in vitro antibacterial assay.

Results:

GKY25 was predicted as an alpha-helical peptide, and its helicity showed probable projection of hydrophobic
and positively-charged amino acid residues. Docking studies showed binding affinity of GKY25 peptide
to gram-positive and outer and inner gram-negative bacterial membranes as -5.7, -6.8, and -4 kcal/mole, respectively.
CAMPR4 analysis predicted the peptide as an AMP. Experimental binding assay showed that the peptide
binds LPS immediately and their interaction was observed at 274 nm.

Conclusion:

Gathering all in silico and in vitro data together, GKY25 is a good drug lead that could be examined
further using clinical isolates of gram-negative bacteria in vitro.

Published: September 2023

Student engagement is the most crucial factor in learning activities because it is the main factor in improving student learning outcomes in class. This study aims to develop instruments and evaluate student involvement in learning mathematics to achieve maximum learning outcomes at school. The population in this study was all high school students in Riau Province. The sample is 150 high school students selected by multiple-stage random sampling based on high, medium, and low student achievement levels. Data analysis in this study was carried out four times: (1) data analysis based on the results of expert assessment of the instrument with the Aiken formula; (2) small-scale validity data analysis with first-order CFA; (3) large-scale data analysis with second-order CFA analysis; (4) descriptive analysis to see the categorization of student learning engagement in Riau Province whether in very good, good, not good and very not good. The analysis using the Aiken formula shows that 24 out of 27 items developed are valid. The first-order CFA analysis shows that the 24 items distributed are valid. The second-order analysis shows that the construct validity of the learning involvement variable is valid and reliable. The analysis of learning involvement results shows that students' involvement in learning mathematics is in the not-good category. The Riau provincial government needs to maximize student learning engagement which can be done by regulating students' effective study hours at school and home. Collaboration between parents and schools must be improved so parents can control student learning outside of school.

Published: September 2023

This research aims at developing an instrument for measuring views on Muhammadiyah ideology that is valid and reliable. This study adapted Borg and Gall’s development model through initial research, planning, initial product development, limited testing, product revision, expanded testing, and product revision. The steps started with initial research to obtain the ideology construct of books related to Muhammadiyah. The ideology construct obtained was used as the basis to arrange instrument items which were then validated by five experts in the fields of measurement, Muhammadiyah ideology, practitioners, and Muhammadiyah cadres by filling the sheet of variable appropriateness with indicators and indicators appropriateness with the statements. The results of the experts’ validation were analyzed with the Aiken formula. The validated instrument was then tested limitedly in the Muhammadiyah regional leadership in Karanganyar, Sragen, and Boyolali, by involving 253 respondents. The result of the test was analyzed using factor analysis and SEM using the Lisrel program. The result of the research shows that the instrument for measuring the views on Muhammadiyah ideology consists of 26 items comprised of seven aspects of Muhammadiyah ideology measurement, including tauhid (two items), living in a social group (three items), Allah’s law (three items), Islamic doctrine (five items), the prophet’s ittiba’ (four items), organization (three items), and Muhammadiyah goals (six items). The instrument fulfills the validity criteria since it has a loading factor between 0.3-0.85(0.3) and CR 0.92 (0.7). The instrument is reliable since Cronbach’s Alpha is 0.8690.7. Since it is valid and reliable, then it is suitable to be used to measure the views on Muhammadiyah ideology in Indonesia.
Satisfaction, Perceived Usefulness, and Therapeutic Alliance as Correlates of Participant Engagement in a Pediatric Digital Mental Health Intervention: Cross-Sectional Questionnaire Study (Preprint)
Authors: Huffman Landry , Lawrence-Sidebottom Darian , Huberty Jennifer , Beatty Clare , Roots Monika , Roots Kurt , Parikh Amit , Guerra Rachael
Published: September 2023

BACKGROUND

Although evidence suggests that digital mental health interventions (DMHIs) are effective alternatives to traditional mental health care, participant engagement continues to be an issue, especially for pediatric DMHIs. Extant studies of DMHIs among adults suggest that participants’ satisfaction, perceived usefulness, and therapeutic alliance are closely tied to engagement. However, these associations have not been investigated among children and adolescents involved in DMHIs.

OBJECTIVE

To address these gaps in extant DMHI research, the purpose of this study was to (1) develop and implement a measure to assess satisfaction, perceived usefulness, and therapeutic alliance among children and adolescents participating in a DMHI and (2) investigate satisfaction, perceived usefulness, and therapeutic alliance as correlates of children’s and adolescents’ engagement in the DMHI.

METHODS

Members (children and adolescents) of a pediatric DMHI who had completed at least one session with a care provider (eg, coach or therapist) were eligible for inclusion in the study. Adolescent members and caregivers of children completed a survey assessing satisfaction with service, perceived usefulness of care, and therapeutic alliance with care team members.

RESULTS

This study provides evidence for the reliability and validity of an adolescent- and caregiver-reported user experience assessment in a pediatric DMHI. Moreover, our findings suggest that adolescents' and caregivers’ satisfaction and perceived usefulness are salient correlates of youths’ engagement with a DMHI.

CONCLUSIONS

This study provides valuable preliminary evidence that caregivers’ satisfaction and perceived usefulness are salient correlates of youths’ engagement with a DMHI. Although further research is required, these findings offer preliminary evidence that caregivers play a critical role in effectively increasing engagement among children and adolescents involved in DMHIs.
Electronic Medical Record Data Missingness and Interruption in Antiretroviral Therapy among Adults and Children Living with HIV in Haiti: A Retrospective Longitudinal Study (Preprint)
Authors: Secor Andrew M. , Célestin Kemar , Jasmin Margareth , Honoré Jean , Wagner Anjuli D. , Beima-Sofie Kristin , Pintye Jillian , Puttkammer Nancy
Published: September 2023

BACKGROUND

Children (aged 0-14 years) living with HIV (CLH) often have lower rates of HIV diagnosis, treatment, and viral load suppression. In Haiti only 63% of CLH know their HIV status (compared to 85% overall), 63% are on treatment (compared to 85% overall), and 48% are virally suppressed (compared to 73% overall). Electronic medical records (EMRs) can improve HIV care and patients, but these benefits are largely predicated on providers having access to high quality data.

OBJECTIVE

We hypothesize that data missingness will be associated with greater interruption in ART treatment (IIT) and that this relationship will be larger among CLH.

METHODS

We assessed associations between patient intake record data missingness and IIT status at 6- and 12-months post ART initiation using patient-level data drawn from iSante, the most widely used EMR in Haiti. Missingness was assessed for TB stage, WHO HIV stage, and weight using a composite score indicator (number of indicators missing). Effect estimates were marginal parameters from multilevel modified Poisson models with robust error variances and random intercepts for facility to account for clustering.

RESULTS

Data were drawn from 50 facilities and comprised 31,457 people living with HIV (PLH) patient records, of which 1,306 (4.2%) were pediatric. Pediatric patients were more likely than adult patients to experience IIT (33.0% vs. 23.4% at 6 months, P<.001) and their patient records had higher data missingness (55.5% of pediatric records had no indicators of interest missing, compared to 74.1% of adult records, P<0.001). Among pediatric patients, each one additional indicator missing was associated with 1.34 times greater likelihood of being IIT at 6 months (95% confidence interval [CI]=1.08–1.66, P=.008) and 1.24 times greater likelihood of being IIT at 12 months (95% CI=1.05–1.46, P=.010). These relationships were not statistically significant for adult patients. Compared to pediatric patients with zero missing indicators, pediatric patients with one, two, or three missing indicators were 1.59 (95% CI=1.26–2.01, P<.001), 1.74 (95% CI=1.02–2.97, P=.041), and 2.25 (95% CI=1.43–3.56, P=.001) times more likely to be IIT at 6 months, respectively. Among adult patients, compared to patients with zero indicators missing, having all three indicators missing was associated with being 1.32 times more likely to be IIT at 6 months (95% CI=1.03–1.70, P=.030), while there was not association with IIT status for the other levels of missingness.

CONCLUSIONS

These findings suggest that improving EMR data quality may enable better quality of care and lead to greater care and treatment engagement. Efforts to improve data quality should consider prioritizing pediatric patients.
App Characteristics and Accuracy Metrics of Available Digital Biomarkers for Autism: Scoping Review (Preprint)
Authors: Ponzo Sonia , May Merle , Tamayo-Elizalde Miren , Bailey Kerri , Shand Alanna J , Bamford Ryan , Multmeier Jan , Griessel Ivan , Szulyovszky Benedek , Blakey William , Valentine Sophie , Plans David
Published: September 2023

BACKGROUND

Diagnostic delays in autism are common, with the time to diagnosis being up to 3 years from the onset of symptoms. Such delays have a proven detrimental effect on individuals and families going through the process. Digital health products, such as mobile apps, can help close this gap due to their scalability and ease of access. Further, mobile apps offer the opportunity to make the diagnostic process faster and more accurate by providing additional and timely information to clinicians undergoing autism assessments.

OBJECTIVE

The aim of this scoping review was to synthesize the available evidence about digital biomarker tools to aid clinicians, researchers in the autism field, and end users in making decisions as to their adoption within clinical and research settings.

METHODS

We conducted a structured literature search on databases and search engines to identify peer-reviewed studies and regulatory submissions that describe app characteristics, validation study details, and accuracy and validity metrics of commercial and research digital biomarker apps aimed at aiding the diagnosis of autism.

RESULTS

We identified 4 studies evaluating 4 products: 1 commercial and 3 research apps. The accuracy of the identified apps varied between 28% and 80.6%. Sensitivity and specificity also varied, ranging from 51.6% to 81.6% and 18.5% to 80.5%, respectively. Positive predictive value ranged from 20.3% to 76.6%, and negative predictive value fluctuated between 48.7% and 97.4%. Further, we found a lack of details around participants’ demographics and, where these were reported, important imbalances in sex and ethnicity in the studies evaluating such products. Finally, evaluation methods as well as accuracy and validity metrics of available tools were not clearly reported in some cases and varied greatly across studies. Different comparators were also used, with some studies validating their tools against the Diagnostic and Statistical Manual of Mental Disorders criteria and others through self-reported measures. Further, while in most cases, 2 classes were used for algorithm validation purposes, 1 of the studies reported a third category (indeterminate). These discrepancies substantially impact the comparability and generalizability of the results, thus highlighting the need for standardized validation processes and the reporting of findings.

CONCLUSIONS

Despite their popularity, systematic evaluations and syntheses of the current state of the art of digital health products are lacking. Standardized and transparent evaluations of digital health tools in diverse populations are needed to assess their real-world usability and validity, as well as help researchers, clinicians, and end users safely adopt novel tools within clinical and research practices.

Authors: Evans Laura , Evans Jay , Fletcher Monica , Abdullah Adina , Ahmed Zakiuddin
Published: September 2023

BACKGROUND

The last 2 decades have been a time of exponential growth and maturation for digital health, while the global burden of respiratory disease continues to grow worldwide. Leveraging digital health interventions (DHIs) to manage and mitigate respiratory disease and its adverse health effects presents itself as an obvious path forward.

OBJECTIVE

We aimed to understand the current digital landscape and enabling environment around respiratory health to reduce costs, avoid duplication, and understand the comprehensiveness of DHIs.

METHODS

This study will follow a scoping review methodology as outlined by Arksey and O’Malley, the Joanna Briggs Institute, and the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) checklist. MEDLINE, Embase, CINAHL, PsycINFO, Cochrane Library, Web of Science, PakiMedNet, and MyMedR databases will be searched along with key websites, repositories, and gray literature databases. The terms “respiratory health,” “digital health,” “South Asia,” and “Southeast Asia,” as well as related terms will be searched. The results will be screened for duplicates and then against the inclusion and exclusion criteria. For the studies included, data will be extracted, collated, and analyzed.

RESULTS

The scoping review was started in July 2023 and will be finalized by February 2024. Results will be presented following the World Health Organization’s classification of DHIs to categorize interventions in a standardized format and the mobile health evidence reporting and assessment checklist to report on the effectiveness of interventions. Further exposition of the evidence extracted will be presented through narrative synthesis.

CONCLUSIONS

As DHIs continue to proliferate, the need to understand the current landscape becomes more pertinent. In this scoping review, we will seek to more clearly understand what digital health tools and technologies are being used in the current landscape of digital health in South and Southeast Asia for respiratory health and to what extent they are addressing the respiratory health needs of the region. The results will inform recommendations on digital health tools for respiratory health in South and Southeast Asia will help funders and implementers of DHIs leverage existing technologies and accelerate innovations that address documented gaps in the studied countries.

The Effect of Push, Pull, and Mooring Factors on Customers’ Switching Intention to Green Cosmetics
Authors: Firdausi Asri Sekar Mawar , Dharmmesta Basu Swastha
Published: September 2023

Nowadays, consumption patterns concern consumers since they have negative impacts on environmental sustainability. Marketers have conducted some efforts to create eco-friendly products. This condition has caused research into green marketing to grow significantly. Various studies have been conducted to examine consumers' behavior intentions toward green products. However, the theory applied to explain the phenomenon still has the potential to be developed. Thus, in this study, the researchers examine the consumers' switching intention from conventional cosmetics to green cosmetics, by applying the migration theory and the push-pull-mooring framework. The push factors are explained by the dissatisfaction variable and the low-quality variable. The alternative attractiveness variable explains the pull factor. Meanwhile, the mooring factors are explained by variety-seeking and the unfavorable subjective norm variables. PLS-SEM is used to analyze 198 consumers of conventional cosmetics. The results indicate that the pull factor is the main factor that supports the consumers' switching intention to green cosmetics, and the second is the push factor. Furthermore, the mooring factors are proven to moderate the effect of the pull factor on consumers' switching intention. On the other hand, the mooring factors are not shown to moderate the influence of the push factors on the consumers' switching intention.
Taurolidine/Heparin Lock Solution and Catheter-Related Bloodstream Infection in Hemodialysis
Authors: Agarwal Anil K. , Roy-Chaudhury Prabir , Mounts Phoebe , Hurlburt Elizabeth , Pfaffle Antony , Poggio Eugene C.
Published: September 2023

Background

Catheter‐related bloodstream infections (CRBSIs) are one of the most prevalent, fatal, and costly complications of hemodialysis with a central venous catheter (CVC). The LOCK IT-100 trial compared the efficacy and safety of a taurolidine/heparin catheter lock solution that combines taurolidine 13.5 mg/ml and heparin (1000 units/ml) versus heparin in preventing CRBSIs in participants receiving hemodialysis via CVC.

Methods

LOCK IT-100 was a randomized, double-blind, active-control, multicenter, phase 3 study that enrolled adults with kidney failure undergoing maintenance hemodialysis via CVC from 70 US sites. Participants were randomized 1:1 to taurolidine/heparin catheter lock solution or heparin control catheter lock solution (1000 units/ml). The primary end point was time to CRBSI as assessed by a blinded Clinical Adjudication Committee. Secondary end points were catheter removal for any reason and loss of catheter patency. On the basis of a prespecified interim analysis, the Data and Safety Monitoring Board recommended terminating the trial early for efficacy with no safety concerns.

Results

In the full analysis population (N=795), nine participants in the taurolidine/heparin arm (n=397; 2%) and 32 participants in the heparin arm (n=398; 8%) had a CRBSI. Event rates per 1000 catheter days were 0.13 and 0.46, respectively, with the difference in time to CRBSI being statistically significant, favoring taurolidine/heparin (P < 0.001). The hazard ratio was 0.29 (95% confidence interval, 0.14 to 0.62), corresponding to a 71% reduction in risk of CRBSIs with taurolidine/heparin versus heparin. There were no significant differences between study arms in time to catheter removal for any reason or loss of catheter patency. The safety of taurolidine/heparin was comparable with that of heparin, and most treatment-emergent adverse events were mild or moderate.

Conclusions

Taurolidine/heparin reduced the risk of developing a CRBSI in study participants receiving hemodialysis via CVC compared with heparin with a comparable safety profile.

Published: September 2023

Advocacy and policy change are powerful levers to improve quality of care and better support patients on home dialysis. While the kidney community increasingly recognizes the value of home dialysis as an option for patients who prioritize independence and flexibility, only a minority of patients dialyze at home in the United States. Complex system-level factors have restricted further growth in home dialysis modalities, including limited infrastructure, insufficient staff for patient education and training, patient-specific barriers, and suboptimal physician expertise. In this article, we outline trends in home dialysis use, review our evolving understanding of what constitutes high-quality care for the home dialysis population (as well as how this can be measured), and discuss policy and advocacy efforts that continue to shape the care of US patients and compare them with experiences in other countries. We conclude by discussing future directions for quality and advocacy efforts.

Authors: Ortega Jordà Mar , Berg-Rodríguez Alexis
Published: September 2023

El artículo expone cómo la realidad política en Colombia en 2021 cuestionó la fortaleza y consolidación de la democracia plena del país, al mostrar elementos de democracia defectiva, esto desde la perspectiva teórica de régimen híbrido. El objetivo es analizar las formas en que la falta de voluntad del gobierno colombiano para garantizar la protección de los derechos fundamentales en todo su territorio contribuye a la fragilidad democrática es ese país; se dialoga entre las características de las nociones de democracia defectiva y la democracia plena de O’Donnell. El análisis es contrastado empíricamente con entrevistas realizadas al campesinado y liderazgo amenazado. Esta realidad se traduce en una falta de voluntad del Estado para frenar los asesinatos en las regiones más desfavorecidas del campo colombiano, constituyendo un reto para el gobierno del actual presidente Gustavo Petro. Finalmente, se propone el acompañamiento internacional como la herramienta más efectiva para reducir asesinatos y acompañar al nuevo gobierno en el proceso de restauración de derechos humanos y consolidación de una democracia plena.

Published: September 2023

Las investigaciones en torno a una ruptura de pareja se plantean medir las estrategias y conductas que las personas llevan a cabo para terminar sus relaciones románticas. Se propone entender la separación de pareja a partir del Modelo de Inversión de Rusbult. Resulta relevante probar el modelo incluyendo elementos psicométricos que nos permitan comprender su validez. De esta forma el propósito de este estudio fue someter a prueba un análisis exploratorio y confimatorio de una escala que mida las conductas que las personas realizan para terminar su relación de pareja. Para ellos se creó una escala de Conductas ante la separación de pareja que su versión inicial contó con 50 reactivos en escala Likert, aplicados en línea a 230 adultos de la Ciudad de México y Área Metropolitana, al inicio del Análisis Factorial Exploratorio se obtuvo una escala final de 18 reactivos distribuidos en 4 factores (alejamiento, confrontación, depresión por separación e infidelidad) que explican el 68,47% de la varianza explicada con una confiabilidad de α = .871. Esta estructura fue corroborada por un Análisis Factorial Confirmatorio. Se concluye que las conductas de separación evaluadas a partir del alejamiento con la expareja, que puede ser por medio de la comunicación o de ejercer conductas que transgreden como una infidelidad, y que afecta principalmente el estado emocional de las personas que lo viven.

Authors: Guillén-Díaz-Barriga Centli , Díaz-Sosa Dulce María , Sánchez Cervantes Cintia Tamara , Mora Miranda Mayra Alejandra
Published: September 2023

HIV risk perception and Intimate partner violence (IPV) are related to HIV infection in women. However, there is a lack of information regarding on the association between risk perception and IPV in the Mexican population. This study aimed to identify and characterize subgroups based on their risk perception through the analysis of latent classes and to evaluate the variables associated with HIV risk perception. An online survey was conducted to assess sexual and preventive behavior, HIV risk perception, and intimate partner violence. Three hundred thirty-two women participated; the sampling was for convenience. Two latent classes were identified: a group with risk perception (85%) and one without risk perception (14.6%). The variables associated with the risk perception were a sexual attraction to men, not having a stable partner, perceiving oneself as at risk of acquiring HIV due to sexual behavior, and the presence of IPV. HIV prevention programs for women must address the stigmas related to HIV, such as the idea that the risk only occurs when they have multiple sexual partners, promote accurate HIV risk perception and prevent IPV in all its expressions and contexts.
Coping with Transgressions by the Romantic Partner: An Inventory Validation and its Correlation with Forgiveness
Authors: Rosales Sarabia Rodrigo Miguel , Aragón Sofía Rivera , Díaz Loving Rolando
Published: September 2023

Almost every person has to deal with transgressions committed by a romantic partner and faces their negative psychological outcomes, and coping strategies might be key to understanding post-transgression dynamics and forgiveness. We tested the construct validity of the Inventory of Strategies for Coping with a Partner's Transgression which include the emotion (E-FCS), problem (P-FCS), and meaning-focused coping strategies (M-FCS) scales. Results replicated the factor structure of each of the three scales through confirmatory factor analysis techniques, tested its reliability with the McDonald’s omega coefficient, and then correlated the scales with forgiveness and resentment, strengthening its construct validity. In general, the validity and reliability of scales were confirmed. Emotion-focused strategies showed a negative correlation with forgiveness, while problem and meaning-focused strategies had a positive correlation. These findings were discussed in the context of theory and their practical implications.

Published: September 2023

La variabilidad de la frecuencia cardiaca (VFC) se utiliza como una señal fisiológica para evaluar la reactividad psicofisiológica al estrés. El análisis en el dominio de la frecuencia de esta señal se ha usado para describir el papel del sistema nervioso autónomo en los procesos de adaptación al estrés. Sin embargo, el uso de medidas de tendencia central para reportar los resultados de distintas poblaciones desestima las diferencias individuales en la reacción frente al estrés. El objetivo de esta investigación fue caracterizar la reactividad cardiaca ante la evocación de eventos estresantes en población universitaria. Participaron 94 estudiantes de nuevo ingreso a la carrera de psicología, de dos universidades de México. Los resultados indican un decremento consistente en la banda de alta frecuencia ante la evocación de eventos estresantes, en comparación con la banda de baja frecuencia. La caracterización de la respuesta autonómica al estrés presenta dos subgrupos acoplados (co-activación y co-inhibición); y uno desacoplado. Nuestros hallazgos, ratifican la viabilidad de la banda de frecuencia alta de la VFC como un indicador estable de reactividad al estrés, y resaltan la importancia de las diferencias específicas de la actividad autonómica en la caracterización de la respuesta fisiológica al estrés.
Competencias en alimentación: una mirada hacia el interior de las preparaciones vegetales licuadas tipo “smoothie”
Authors: Reyes María Silvina , Vignatti Charito , Pirovani María Elida
Published: September 2023

Este trabajo tiene un doble propósito: analizar competencias en alimentación (CA) en estudiantes de la Universidad Nacional del Litoral (Santa Fe, Argentina) y valorar la aceptabilidad de 3 formulaciones de preparaciones vegetales licuadas, “smoothies” o batidos vegetales (BV) en dicho estudiantado. Las CA se estructuraron en torno a cuatro ejes: los alimentos, dieta y salud; la seguridad alimentaria; la sensibilización como consumidores responsables y, por último, la cocción y la manipulación de alimentos. Para el análisis de estas se realizaron 4 grupos focales (GF) con estudiantes de diferentes carreras. Por otra parte, se elaboraron 3 formulaciones de BV: F1: (frutilla, naranja, banana y manzana -base-, F2: base con agregado de avena y F3: base con agregado de chía). Para evaluar la aceptabilidad de estos BV, se diseñó y desarrolló una aplicación informática, la cual permitió aplicar un test hedónico de 9 puntos a 113 estudiantes. Todas las formulaciones presentaron valores de aceptabilidad elevada, diferenciándose la F3. Por lo anterior, se concluye que los BV se constituyen como una estrategia de consumo saludable que favorecería el consumo de frutas y hortalizas por parte de los estudiantes universitarios.

Studies have shown that hormones have endocrine disrupting properties, which characterize them as potentially toxic to the aquatic environment. This study aims to monitor the water along Prosa Stream/Anhanduí River monthly, to evaluate its contamination by the hormones 17β-estradiol (E2) and 17α-ethinylestradiol (EE2). Dispersive liquid-liquid microextraction (DLLME) was used for analyte extraction, with acetone as a disperser solvent and carbon tetrachloride as the extraction solvent, followed by high-performance liquid chromatography with ultraviolet detector (HPLC-UV) as the analytical tool. The results of this application in natural samples indicated the presence of the natural hormone E2 in approximately 72% of the points evaluated, with its concentration values between 48 µg L-1 and 175 µg L-1. In contrast, it was not possible to quantify the concentrations of synthetic hormone EE2, as these values were below the detection limit of the analytical method applied. Even though there is no national environmental legislation that limits amounts of hormones in surface water, these contaminations are significant, due to their already known toxicological potential. It was evident that along the river from its origin to the exit of the city there was the appearance and increase of the contamination of the waters by the hormone E2, thus it is clear that the urbanization around the rivers has become an environmental and health problem for providing the contamination of the aquatic environment.

Constructed wetlands are green technologies, nature-based solutions, that use phytoremediation for the treatment of wastewater studied in domestic, industrial, and agricultural uses and products such as hydrocarbons and some emerging pollutants. The objective is to analyze the efficiency of the constructed wetlands for the removal of heavy metals, nutrients such as phosphorus, and nitrogen in wastewater treatment. This study presents the results of contaminant removal from two types of constructed wetlands; single-stage and two-stage, which determine their efficiency. The removal of COD, BOD, phosphorus, fats, nitrogen, solids and others, showed similar efficiencies for each plant, with removal ranges between 16% and 95% relative to each pollutant analyzed. As a complement, the concentration of heavy chromium VI, cadmium, and total iron were reduced and analized thlrough the UV-VIS spectrophotometric method, which from three absorbance measurements for each metal, with wavelengths of 540 nm, 228 nm, 8 nm, and 510 nm, respectively, efficiencies of 62% and 85% were found for chromium VI removal; 43% and 53% removal for cadmium; 37% and 53% removal for total iron, results according to single-stage and two-stage plants.

Published: September 2023

The increase in solid waste generation and the necessity for more efficient management are issues of modern society. Nonetheless, its multifactorial nature makes this problem complex and searching for solutions not simple. In this way, this type of study requires tools that allow simultaneous incorporation of multiple variables. Data Envelopment Analysis (DEA) is a multivariate and non-parametric technique that analyzes a unit’s efficiency by comparison. The bibliography indicates that this technique applied to ​solid waste management systems is already a reality. However, there has been no bibliometric reports on current and future research trends about the theme. Thus, this paper aims to fill this gap through a bibliometric analysis, using the literature from the Scopus database, considering articles from journals and conferences published until February 2022. The results indicate that this topic research began in the 21st century, with an expressive rise since 2016, highlighting the topic’s relevance and potential for future research application. In addition, China, Spain, Italy, and the USA are the most productive countries, but cooperation is still weak. Hence, there is a potential to disseminate this research field and promote greater interinstitutional cooperation. Moreover, the findings reveal that DEA is an adequate tool to analyze solid waste management systems. Lastly, this study offers some future research suggestions, based on the results obtained through the bibliometric analysis.

Navigating the Nexus: Exploring the Relationship between Intellectual Capital, Financial Performance, and Firm Value
Authors: Surya Andi
Published: September 2023

While previous study has drawn attention to the relationship between intellectual capital, financial performance, and firm value, there is still room for empirical research into the role of mediating factor between them. This research aims to determine the role of intellectual capital and financial performance in improving the firm value of the manufacturing companies listed on the Indonesia Stock Exchange. For this study, we collected financial reports from seven manufacturing companies over five years from 2017 to 2021. We employed a quantitative method, specifically path analysis using linear regression analysis, to test our hypotheses. The results demonstrate that there is no effect of intellectual capital on both financial performance and firm value, and no mediating effect exists either. However, the effect of company performance on firm value was established in the study. The research results create a chasm, suggesting three variables to think about when making investment decisions.
Thermal performance experiment and numerical simulation of micro-PCM cement mortar composite wall
Authors: Liang Mei
Published: September 2023

In order to reduce the heat transfer between indoor and outdoor environments
and reduce the influence of outdoor ambient temperature fluctuation on the
indoor environment, adding micro-PCM to the building envelope is one of the
effective means. Micro-PCM can ?intelligently? control temperature by
absorbing or releasing heat during phase change to maintain temperature
stability. In this paper, the phase change temperature-adjustable mortar was
prepared by using micro-PCM with a phase change temperature of 25?C, and
was painted on the surface of cement wallboard (300 ? 100 mm) to form a
phase change thermostatic mortar layer with a cross-section size of 300 ? 20
mm. The solar radiation on the outer surface of the building envelope was
simulated by an incandescent lamp. The influence of micro-PCM on the
temperature control performance of cement wallboard was tested. The thermal
performance of the PCM wallboard was simulated by COMSOL software. Results
show that compared with ordinary cement wallboard, when the micro-PCM
content is 40%, the maximum temperature of the inner wall can be reduced by
5.17?C, and the time to reach the maximum temperature is delayed by 145
minutes. The temperature fluctuation amplitude of the inner wall is reduced
by 1.90?C, and the maximum instantaneous heat transfer is reduced by 22.202
W/m2.
