BACKGROUND

In 2012, the country of Georgia established an electronic integrated disease surveillance system (EIDSS) for acute hepatitis B virus (HBV) infection. All medical facilities must report laboratory-confirmed acute HBV cases to the regional public health centres (PHCs) within 24 hours, which are subsequently registered in EIDSS.

OBJECTIVE

To evaluate the acute hepatitis B surveillance system in Georgia in order to identify areas for improvement and develop recommendations that enhance its capacity to inform prevention and response efforts, supporting the elimination of viral hepatitis.

METHODS

For the evaluation of acute HBV cases notified in 2015-2020, we used the Centres for Disease Control and Prevention updated guidelines. We assessed data completeness by calculating the percentage of missing values for key variables. We assessed simplicity, acceptability and flexibility by describing surveillance processes and by surveying PHC epidemiologists. We evaluated representativeness by comparing cases registered in EIDSS with cases registered in hospital discharges. We assessed timeliness by calculating the number of days from the date of diagnosis to the date of notification in EIDSS. We calculated the positive predictive value (PPV) as the proportion of cases notified during 2018-2020 having documentation of confirmatory tests in their medical records, meeting the confirmed case definition.

RESULTS

During 2015–2020, 270 cases of acute viral hepatitis B were reported to EIDSS. All notified cases were HBsAg positive. However, only 53% of the 19 key variables were complete. Hepatitis B test results were missing in most reported cases, despite 82% being classified as "confirmed". Simplicity and acceptability of the system were affected by 30% respondents experiencing challenges with the EIDSS reporting form. The system had limited flexibility due to cumbersome procedures to implement any changes. Representativeness was limited, as only 41% of confirmed cases recorded in the hospital discharge database were reported to EIDSS. The average notification delay was 72 hours. Among 106 cases notified in 2018-2020, 67 met the case definition, leading to PPV 63%.

CONCLUSIONS

The surveillance system for acute HBV infection was timely but not representative and did not correctly ascertain cases. We recommend reconsidering the statutory notification time of 24 hours, revising notification forms and providing clear guidelines for data entry, and reporting of all test results needed for adequate case classification to enhance data completeness and reliability of case classification.

BACKGROUND

Females with irregular or unpredictable cycles, including those with polycystic ovary syndrome (PCOS), have limited options for validated at-home ovulation prediction. The majority of over-the-counter ovulation prediction kits use urinary luteinizing hormone (LH) indicators that were optimized for those with regular menstrual cycles exhibiting a predictable mid-cycle LH surge. Artificial intelligence (AI) holds potential to address this health deficit via a smartphone-based salivary ferning ovulation test. Research on populations with irregular menstruation and PCOS can be challenging due to the duration and frequency of menstrual cycles.

OBJECTIVE

The objective of this study was to determine the feasibility for participants with diverse menstrual cycle lengths to complete study tasks designed to train and develop an AI model for salivary-based ovulation prediction.

METHODS

Participants were recruited for two menstrual cycles where retention, engagement, and adherence were evaluated. Participation entailed remotely collecting and uploading daily data (saliva, LH values), attending lab visits, and returning biological saliva samples.

RESULTS

Of the 133 females recruited from February to October 2023 via targeted patient messages and a public research website, 69 were eligible (age 19 to 35 years old at enrollment, currently menstruating, able to read and comprehend English, weigh more than 110 pounds, have an active primary care or gynecological provider, and able to commute to the Mass General Hospital main campus within 10 days of their ovulatory event). Of those who received a Study Kit, 57% of participants (n=17) began data collection, 31% of participants (n=9) provided data for one menstrual cycle, and 24% of participants (n=7) completed the study.

CONCLUSIONS

To optimize future scaled participant completion, the study design would include a more targeted recruitment message to address the high ineligibility status, to streamline study procedures to ease participant burden, and to incorporate health education to equip participants with ovulatory health information to ameliorate the potential stress impacts of observing anovulation. After optimization, when scaled, this study design will provide an AI model with sufficient data to develop a smartphone-based ovulation predictor specifically tested on females with irregular or unpredictable cycles, including those with PCOS. Well informed study design is the foundation to AI advancement and femtech growth, particularity for ovulatory and fertility digital health.

Reproductive control of invasive, feral, and domesticated animals is an urgent public health issue. Immunological vaccines are employed as an emerging strategy to target different components of the reproductive system, to achieve immunocastration. Successful use of immunogens against parts of the oocyte, spermatozoon, gonadotropin-releasing hormone (GnRH), and luteinizing hormone receptor (LHr) has been reported. In this work, a recombinant DNA vaccine was prepared (P2GnRHrP30) by the fusion of the first extracellular domain of the canine GnRH receptor (GNRHr) gene to the P2 and P30 tetanus toxoid epitopes. This construction was cloned in the pCI-NEO mammalian expression vector and evaluated as an immunocontraception DNA vaccine in male mice. The developed vaccine was demonstrated to be safe, and capable of reducing serum testosterone levels and causing testicular atrophy. Our work indicates that the first extracellular domain of the GnRHr gene may act as an immune target for reproductive control and potentially be used as a non-surgical sterilization procedure in mammals.

Desde hace unas décadas hay un creciente interés por consumir alimentos funcionales, estos productos impactan de manera benéfica a la salud del consumidor, incrementándose así la demanda para que los ingredientes y aditivos alimenticios posean características tecnofuncionales. La población actual busca que los alimentos que van a consumir le aporten, en conjunto, una combinación de características organolépticas aceptables a los sentidos y que, a su vez, las propiedades químicas y fisicoquímicas proporcionen beneficios a la salud. Dentro de esta gama de ingredientes se encuentran las maltodextrinas y los compuestos derivados del almidón, que se emplean como aditivos y que pueden cumplir con este objetivo gracias a su naturaleza química y estructural (pues son agentes que pueden modificar texturas además de otras aplicaciones en la industria alimentaria). Aunado a esto, se ha demostrado que la modificación del almidón mejora las propiedades físicas y funcionales de los almidones nativos; es por ello que la investigación se ha orientado a obtener maltodextrinas modificadas, para potenciar su aplicación en la industria al formular o reformular alimentos. En los últimos años se han realizado estudios respecto a la generación/producción y funcionalidad de maltodextrinas modificadas, obteniéndolas a partir de dos vías: hidrólisis de almidones modificados y modificación de maltodextrinas previamente obtenidas por la hidrólisis de almidón. Las principales modificaciones efectuadas en maltodextrinas son químicas, específicamente la esterificación y acetilación empleando ácidos orgánicos, ácidos inorgánicos, anhídridos o cloruros de acilo. Este artículo brinda información general respecto a la estructura, obtención y aplicaciones de las maltodextrinas modificadas.

De la vis impresa de Hiparco a la cantidad de movimiento de Newton
Authors: Álvarez García José Luis
Published: February 2025

La explicación que Aristóteles (384-322 a.n.e.) daba al fenómeno del lanzamiento de proyectiles nunca convenció a los expertos. Hiparco de Nicea, en el siglo II a.n.e., plantea el concepto de vis impresa para explicarlo. Los eruditos del medioevo, los pensadores árabes y, más tarde, filósofos de las universidades de Oxford y París continuaron los estudios para la explicación de este fenómeno, desarrollando el concepto planteado por Hiparco hasta llegar al concepto de cantidad de movimiento expuesto en Los Principia de Newton, que es uno de los grandes logros en la historia del pensamiento científico y ahí Newton introduce el concepto de masa. No obstante, los espectaculares éxitos de la física newtoniana, una de las más sorprendentes características de la historia de la física es la confusión que rodea a la definición de masa, que es el término clave de la dinámica.

Las gotas se encuentran a nuestro alrededor, en todo momento, y para estar presentes en todo momento sabemos poco de ellas. Espero que este artículo pueda clarificar algunos de los fenómenos y aplicaciones que tienen la vasta y fascinante física de las gotas.
Natural Compounds from Aureobasidium sp. TD-062: A New Frontier in Targeting BlaR1 Protein
Authors: Chaturvedi Swapnil , Sarethy Indira P.
Published: February 2025

Aureobasidium sp. strain TD-062, a microcolonial fungus, was isolated from the Thar Desert, India, and it’s aqueous and ethyl acetate extracts were evaluated for antimicrobial activity against clinical isolates of Pseudomonas aeruginosa (sputum), Escherichia coli (pus, blood, and urine), Klebsiella pneumoniae (urine), and Proteus. The ethyl acetate extract was analysed by gas chromatography-mass spectrometry (GC-MS) and examined for toxicity using ProTox-II software. Three compounds, selected based on toxicity and safety profiles, were analysed for molecular docking on BlaR1, a protein that induces antimicrobial resistance in bacteria. The ethyl acetate extract was shown to exhibit antimicrobial activity against clinical pathogens. GC-MS analysis showed that squalene, stigmasterol and delta-tocopherol had lower toxicity profiles. Molecular docking analyses demonstrated that stigmasterol exhibited the highest binding affinity (-8.9 Kcal/mol), compared to positive control clavulanic acid (-6.7 Kcal/mol), suggesting its potential as a potent BlaR1 inhibitor. These findings underscore the bioactive potential of Aureobasidium sp. TD-062 as a promising source of bioactive compounds to combat antimicrobial resistance. The identification of squalene, stigmasterol, and delta-tocopherol as lead compounds for drug development represents a significant advancement in the search for novel antimicrobial agents to address the growing global threat of antimicrobial resistance.

Published: February 2025

This study aimed to develop and evaluate a bioformulation combining Trichoderma asperellum MSU007 and the plant growth-promoting rhizobacterium (PGPR) Bacillus velezensis MSU01 to enhance rice growth. Coexistence assays demonstrated that T. asperellum MSU007 and the PGPR B. velezensis MSU01 could grow concurrently without mutual inhibition. A powdered bio-formulation was created that showed effective water solubility and moisture content stability across the three formulations. Viability assessments indicated that T. asperellum MSU007 and the PGPR maintained high survival rates over a 60 day storage period, with formulation 3 (T. asperellum MSU007 and B. velezensis MSU01 at a 3:1 ratio) consistently exhibiting the highest viability. The effect of the bioformulation on rice growth was significant. Formulation 3 was the most effective in enhancing rice seed germination and seedling growth. It achieved 100% germination by the fourth day and consistently promoted improvements in shoot and root lengths, as well as in the fresh and dry weights of shoots and roots. Formulations 1 and 2 also showed positive effects but were less effective than formulation 3. In summary, the Trichoderma-PGPR bioformulations, particularly formulation 3, significantly enhanced rice growth, offering a promising solution for improving crop yield.

Authors: Aladhadh Mohammed , Abdallah Emad M.
Published: February 2025

Camel milk has been an integral component of diets in the Middle East for millennia. The current study aimed to evaluate microbial changes in pasteurized camel and cow milk using culture-based methods. We examined bacterial growth in raw and pasteurized camel and cow milk during 17 days of refrigerated storage at 4 °C. Raw camel milk had a mean initial bacterial count of 4.13 × 10³ CFU/mL, peaking at 2.87 × 106 CFU/mL by day 17. Pasteurization reduced the count to 2 × 10¹ CFU/mL, rising to 40 × 104 CFU/mL by day 17. Raw cow milk started at 1.08 × 104 CFU/mL, reaching 3.15 × 106 CFU/mL, while pasteurized cow milk increased from 31.12 CFU/mL to 4.06 × 106 CFU/mL. Coagulase-positive Staphylococcus aureus and Lactobacillus spp. exhibited significant proliferation in raw camel and cow milk. The growth reached a high point of 5.27 × 104 CFU/mL for coagulase-positive S. aureus and 3.74 × 104 CFU/mL for Lactobacillus spp. in raw camel milk. In raw cow milk, it reached a high point of 1.20 × 105 CFU/mL for coagulase-positive S. aureus and 5.0 × 105 CFU/mL for Lactobacillus spp., these results show that these microorganisms grow in different ways in camel milk and cow milk. This shows how vulnerable raw milk is to microbial growth. Pasteurized samples showed no S. aureus or Lactobacillus spp. growth, confirming pasteurization’s effectiveness. The study detected no fungal or pathogenic contamination. In conclusion, camel milk exhibited higher initial bacterial counts and slower bacterial growth than cow milk, but supported more sustained microbial proliferation over time. Pasteurization was equally effective for both types, eliminating Lactobacillus spp. and reducing bacterial loads significantly.

Who Rewards Appropriate Levels of Professional Skepticism?
Authors: Brazel Joseph F. , Leiby Justin , Schaefer Tammie J.
Published: February 2025

In this article, we provide a practitioner summary of our paper “Who Rewards Appropriate Levels of Professional Skepticism?” (Brazel, Leiby, and Schaefer 2025; hereafter BLS). Recent research suggests that audit supervisors who reward appropriate skeptical behavior, regardless of the outcome, appear to develop staff that are more likely to detect and convey fraud red flags to their superiors. In BLS, we first identify audit supervisors who are more likely to reward appropriate skepticism. We then investigate which personality traits, knowledge, and incentives are associated with supervisors who reward appropriate professional skepticism even when no misstatement is identified. We find that trait skepticism, especially suspending one’s judgment, drives the evaluations of professional skepticism in our setting. Also, we observe that when supervisors believe that their own audit partner will view the skepticism favorably, they “pay it forward” by rewarding their own staff who engage in skepticism.

Análisis bioético de la normativa jurídica internacional para el tratamiento de embriones supernumerarios de las técnicas de reproducción asistida: comparativa entre España y Ecuador
Authors:   Universidad Católica del Ecuador Sede Ibarra, Arias Pardo Luis Martin
Published: February 2025

La bioética se puede entender como una rama de la ética que se ocupa de los problemas morales surgidos en el ámbito de la vida y la salud. Por otro lado, los embriones supernumerarios, por su parte, son aquellos embriones que han sido creados durante los procesos de técnicas de reproducción asistida, pero que no son implantados en el útero materno. Finalmente, las técnicas de reproducción asistida comprenden diversos procedimientos médicos que facilitan la concepción en parejas que enfrentan problemas de fertilidad. El objetivo del estudio, se centró en realizar un análisis bioético de la normativa jurídica internacional para el tratamiento de embriones supernumerarios generados a partir de técnicas de reproducción asistida, centrado en la comparativa entre España y Ecuador. La investigación se engloba en un enfoque cualitativo, de carácter analítico, no experimental y transversal, desarrollado a partir de una investigación de tipo bibliográfica-documental, que tuvo como finalidad realizar un análisis bioético de la normativa jurídica internacional para el tratamiento de embriones supernumerarios de las técnicas de reproducción asistida. Al finalizar el estudio se concluyó que, España cuenta con una legislación clara (Ley 14/2006) sobre embriones supernumerarios, balanceando avance científico y ética. Ecuador, en cambio, carece de una regulación integral, creando incertidumbre. Se necesita una normativa internacional armonizada para proteger los derechos humanos y promover prácticas éticas en reproducción asistida, usando el modelo español como referencia para Ecuador.

Coral reefs are complex ecosystems that serve as a habitat of diverse range of organism such as multispecies of fish, invertebrates, and marine plants. Their role is also crucial in maintaining the health and balance of the surrounding environment. However, as of present, the ecosystems are threatened by destructive and unresponsible fishing, climate change, and rising sea temperatures. Hence, this study utilizes a mathematical model, building on insights from previous study, to investigate the impact of grazing intensity on coral – macroalgae interactions. The objectives of this study are to extend the analysis of coral reef models analytically and numerically. Linear stability analysis was performed to reveal the stability of each steady state and the corresponding bifurcation points were determined. In result, we simulated bifurcation diagrams using MATCONT package to illustrate interactions between macroalgae and coral by varying macroalgae grazing intensity parameter. The study found the presence of bistability behaviour in the system. This result gave a deeper understanding of grazing intensity effects on coral reef ecosystems with different initial population. The findings offer valuable insights for conservation and adaptive management strategies while facing environmental challenges.

Researchers have formulated the Brinkman–viscoelastic model to study the convective heat transfer of viscoelastic fluids traversing porous media recently. Nevertheless, they did not employ nanofluids. Currently, scientists and researchers are employing nanofluids and hybrid nanofluids in their studies, products, and technologies due to their ability to enhance the transfer of heat. Therefore, the aim of this research is to study the heat transfer of a viscoelastic fluid with nanoparticles as it moves over a horizontal circular cylinder in a saturated porous region at the lower stagnation point. The model, described by a collection of partial differential equations, is simplified into solvable equations by utilizing non-dimensional and non-similarity variables. The simplified system of equations is then solved using the Runge–Kutta–Fehlberg technique and the outcomes are verified through comparative study. It has been found that the temperature goes up when the Brinkman parameter, the viscoelastic parameter, and the volume fraction of nanoparticles are all raised. This temperature rise indicates convective heat transfer.

Published: February 2025

Социальные сети играют важную роль в продвижении научных журналов. Telegram – популярный мессенджер с функцией социальной сети – еще недостаточно изучен в этом контексте. Наше исследование направлено на изучение возможностей Telegram для продвижения научных журналов и обмена опытом построения эффективной коммуникации с целевой аудиторией. В качестве эмпирической базы использовался Telegram-канал российского научного журнала Modern Electronic Materials. Канал решает задачи увеличения числа авторов, взаимодействия с целевой аудиторией и повышения охватов. На этапе создания канала авторы журнала (более 1000 человек) были разделены на четыре сегмента по возрасту, ученой степени и должности. Для каждого сегмента был создан собирательный персонаж с определенными мотивами и барьерами взаимодействия с журналом. Персонализация контента в канале с помощью метода персон позволяет улучшить взаимодействие с аудиторией и получить приток подписчиков. После достижения отметки в 100 подписчиков канала проведен опрос, который конкретизировал интересы и потребности целевой аудитории для дальнейшего построения эффективной коммуникации. Регулярная оценка и анализ целевой аудитории Telegram-канала научного журнала необходимы для обеспечения релевантности контента, оптимизации стратегии продвижения и рационального распределения ресурсов.
CLIMATE RISK AND THE PREDICTABILITY OF JUMPS IN GREEN ASSETS
Authors: Prodromou Tina , Demirer Riza
Published: February 2025

This paper shows that climate uncertainty can help predict the size and direction of intraday jumps in green assets, both in and out-of-sample. Using tick data to capture the size and intensity of intraday jumps, we find that news that relate to transition climate uncertainty including international summits and climate policy, particularly those that could be interpreted as bad news for brown industries, are the most dominant predictors of jumps in green assets compared to proxies of physical climate risks. Our findings provide a novel perspective to the role of climate uncertainty as a driver of idiosyncratic tail risk and jump innovations in green assets and imply that pricing models that incorporate jump risk as a risk factor can be improved by exploiting the predictive power of climate uncertainty over jump dynamics.

The predatory potential of natural enemies plays an important role in regulating pest populations. This study evaluated the effects of four fungicides on the predatory potential of a predatory mite Neoseiulus longispinosus against Tetranychus urticae. Prey consumption began at the protonymph stage of the predatory mite and was significantly reduced under fungicidal treatments compared to the control. The lowest consumption of T. urticae eggs and protonymphs occurred in the metalaxyl + mancozeb treatment, while the highest was observed in the thiophanate methyl treatment. The predation parameters, including cumulative consumption (C₀), stable predation rate (ψ), and finite predation rate (ω), were significantly reduced in mancozeb-based treatments but remained unaffected in thiophanate methyl. Simulated projections showed that thiophanate methyl-treated predators maintained the highest prey consumption over 90 days on the log scale (log 6.47 for eggs and log 6.07 for protonymphs of T. urticae). The varying impacts of fungicides on N. longispinosus highlight the need to select fungicides compatible with predatory mites to sustain effective pest management in agroecosystems.
Prediction of the Natural Gas Compressibility Factor by using MLP and RBF Artificial Neural Networks

Published: February 2025

The compressibility factor indicates the deviation of the real natural gas from the ideal behavior. It is one of the most important parameters in the natural gas industry. In the present study, two different types of neural networks – multi-layer perceptron (MLP) and radial basis functions (RBF) – were used to predict the compressibility factor Z of natural gas. The pressure, temperature, and speed of sound (SoS) were chosen as input parameters for the artificial neural network (ANN) models. The training and testing of the MLP-ANN and RBF-ANN were carried out on the basis of 151 days of continuous measurements. Different variants of both types of neural networks were implemented and a comparative analysis of their modeling capabilities was performed. The models developed show a very high prediction accuracy, with the results obtained showing a certain advantage of the RBF-ANN. The comparative analysis was performed on the basis of standard performance indicators such as R2
, root mean square error (RMSE), mean square error (MSE), mean absolute error (MAE). The present study shows an intelligent method implemented in two different variants to determine the compressibility factor of natural gas without the need to use the equation of state.
