Authors: El Sheikh Mariam Z , Young Jim , Panagiotoglou Dimitra , Cooper Curtis , Cox Joseph , Martel-Laferrière Valérie , Walmsley Sharon , Klein Marina B
Published: February 2025

Background:

Direct-acting antivirals (DAAs) for hepatitis C virus (HCV) were approved in Canada in 2013. By 2018, treatment restrictions had been lifted in all provinces, making DAAs universally accessible. Here, we aim to assess progress toward HCV elimination in the DAA era (2014–2022) within the Canadian Co-infection Cohort.

Methods:

The CCC is a multisite open cohort of people living with HIV-HCV coinfection with cohort visits scheduled biannually. We calculated annual cure rates overall by province and key population: gay bisexual and other men who have sex with men, people who inject drugs, and Indigenous peoples.

Results:

Among the 952 participants eligible for DAAs, 65% (n = 623) were cured and 3% (n = 26) achieved late clearance without treatment by the end of the study period. Of the 35% (n = 303) who were not cured, 46% (n = 138) were lost to follow-up, 31% (n = 95) died, and 23% (n = 70) had insufficient data to determine their cure status. Annual cure rates increased from 2014 to 2019 and then decreased across the cohort and in all key populations. From 2015 to 2018, gay bisexual and other men who have sex with men had the highest cure rates, but by 2019 people who inject drugs and Indigenous peoples caught up. Annual cure rates dropped in all provinces with the onset of the COVID-19 pandemic (after 2019).

Conclusions:

Universal accessibility of DAAs was an important step toward HCV elimination among people living with HIV-HCV coinfection, but this is not sufficient alone. Efforts are needed to re-engage those who remain uncured and reduce mortality in people living with HIV-HCV coinfection.

Published: February 2025

Background:

We aimed to summarize the evidence on the use of discrete choice experiments (DCEs) and conjoint analyses to quantify stakeholders’ preferences for screening programs for type 2 diabetes (T2D) and liver diseases, with a specific focus on metabolic dysfunction-associated steatotic liver disease (MASLD).

Methods:

For this scoping review, five databases (MEDLINE [PubMed], PubMed Central, EMBASE [Ovid], Europe PMC, Google Scholar) were searched with the assistance of a librarian, and deduplicated records were screened by two independent reviewers. Inclusion criteria: using DCE/CA, addressing screening programs for T2D and liver disease, published in English, French, or Spanish after January 1990.

Results:

Among 2,282 studies, 9 (7 from high- and 2 from low-income countries) elicited preferences for screening for liver disease (n = 1), hepatitis C (n = 1), hepatitis B (n = 1), hepatocellular carcinoma (n = 2), noncommunicable diseases (n = 2), diabetic retinopathy (n = 1), and cardiovascular diseases (n = 1). No studies addressed MASLD screening in T2D. Stakeholders included patients (n = 3), health care providers (n = 1), patients plus health care providers (n = 1), and the general population (n = 3). Studies used 18 structure, 6 process, and 4 outcome attributes. Screening sensitivity, setting, duration, provider, and cost were the most important structure attributes in participant choices. Physician support for treatment was the preferred process attribute. Outcome attributes were the least used, but of major importance (screening adherence followed by treatment) when considered.

Conclusions:

With no study focusing on MASLD screening in T2D, our scoping review highlights the need to develop a DCE addressing this topic to better design a patient-centred continuum of care.
Ismétlés és innováció drámai művekben
Authors: Szemes Botond , Nagy Mihály
Published: February 2025

Tanulmányunkban egy olyan módszert ismertetünk, amellyel drámai szereplők megszólalásainak hírértéke mérhető össze kvantitatív módon. Innovatívnak tekinthető minden olyan szereplő, aki gyakran dolgoz ki a korábbiaktól eltérő jelentést; fenntartó vagy ismétlő funkciót lát el az a karakter, aki inkább a korábban kialakult diskurzus megismétlését (és ezáltal megerősítését) végzi el. Az összehasonlítás alapja a szereplői mondatokhoz az SBERT algoritmus segítségével hozzárendelt beágyazási érték. Ugyanakkor egy karakteren belül is megfigyelhető innováció és ismétlés kettőssége: a módszer ezt is vizsgálhatóvá teszi a mondat-szintű elemzés során. A szereplők páros összehasonlítása lehetővé teszi továbbá, hogy a közöttük lévő viszonyokat irányított gráfként ábrázoljuk, amivel a színművek hálózatos megjelenítésének kérdéséhez is hozzá kívánunk járulni. Az eljárást alkalmazva általános műfaji különbségeket azonosítunk Shakespeare tragédiái és komédiái között a bennük érvényesülő nemi szerepek alapján. Az általános mintázatok mellett a módszer az egyes színművek és szereplők újfajta értelmezése számára is alapot teremt, ami a szoros szövegolvasás és a statisztikai-nyelvtechnológiai módszerek együttes alkalmazhatóságára is rávilágít.

The pebbles from the chicken digestive tract (gastroliths) in their colorless, green and amber tones are tabular and sub-rounded, matte, with physical and x-ray diffraction characteristics typical of industrial bottle glass. Total and spot chemical analyzes carried out by XRF and SEM/EDS show that the raw material was quartz in the form of pure sand, possibly, and as pigments iron, chromium, perhaps sulfur compounds. Iron was the main pigments for the green gastrolith, and iron-chromium and sulfur for the amber. The chickens must have ingested glass pebbles from fragmented and comminuted bottles, due to the lack of stones and minerals of a compatible size (a few mm or more) for crushing and grinding food. It is known that there is no hard rock in more than 90% of the outcropping land in the state of Acre, and in Feijó nothing is known, except for those that have been arriving in recent decades from Rondônia, and used in thousands of tons, in paving the BR -364 and neighboring areas, and in civil construction in general. A true “geological contamination”. They will certainly reach the digestive tract of animals in Acre.
MOSQUEIRO E GEOLOGIA: UM IMBRICAMENTO NA MINHA VIDA

Published: February 2025

A Ilha de Mosqueiro, localizada no município de Belém do Pará, é uma área de rica diversidade cultural (carnaval, gastronomia, artesanato etc.) e natural com suas belas praias de água doce, trilhas ecológicas e turismo na natureza. Reconhecida por suas paisagens e importância geológica, com as falésias de algumas praias apresentando perfil laterítico imaturo, a região apresenta características únicas que a tornam um ponto de interesse para pesquisadores e para o público em geral. O acesso é facilitado por transporte urbano regular via BR-316 e PA-391, além de alternativas particulares por via fluvial, uma vez que o serviço público não mais disponibiliza um transporte regular nessa modalidade. Os dois meios de transporte desempenham um papel crucial na conexão entre a cidade e as áreas da ilha. Ainda é viva na minha memória a primeira viagem a Mosqueiro através do navio Presidente Vargas na década de 1960
Геоморфологические аспекты использования земель, нарушенных в ходе горной добычи
Authors: Лукашов А.А. , Акпамбетова К.М.
Published: February 2025

Ежегодно нарушаемая горными разработками площадь земель достигает порядка 0,3–0,4 млн. га. Во многих странах проводятся мероприятия по сокращению площади, занимаемой отвалами, терриконами и пустошами. Широкий размах приобрели работы по преобразованию бесплодных нарушенных земель в пригодные для использования. При этом улучшаются не только земли, нарушенные горными разработками, но и антропогенные пустоши другого происхождения. Больше всего земель выводится из строя горными разработками и при строительстве линейных сооружений. Авторы отмечают, что на территории Карагандинского угольного бассейна в результате прогибания поверхности произошло оседание фундамента зданий, смещение блоков стен, обрушение потолочных перекрытий. Максимальные величины прогиба составляют 70–80 % от мощности выработанного пласта. Исследования показали, что в результате многолетнего ведения подземных горных работ на поверхности, в промзонах рудников и на близлежащих территориях образуется множество воронок обрушения. Подчеркнуто также, что под влиянием шахтного водоотлива формируется депрессионная воронка площадью в десятки квадратных километров. Территории вокруг шахт из-за многочисленных провалов на поверхности являются зонами повышенной опасности. Деформации пород, залегающих над выработками, носят различный характер— от плавных, без нарушения сплошности пород, до их полной дезинтеграции. В статье сделаны выводы, что при извлечении твердых полезных ископаемых осуществляется целый комплекс подготовительных, текущих и последующих сопряженных горнотехнических мероприятий, которые приводят к изменению геолого-геоморфологических, гидрологических и метеоро-логических условий в районе добычи и на смежных землях.

Published: February 2025

В условиях полевого опыта изучено влияние действия и последействия органических удобрений на основе помета на качественный и количественный состав гумуса в черноземе оподзоленном тяжело-суглинистом. Установлено, что внесение помета и компостов на его основе способствовало повышению содержания общего углерода. На контроле(без внесения удобрений) содержание общего углерода было на уровне1,7 %. После внесения помета, компоста(помет+ солома) и компоста(помет+ луз-га) в дозе10 т/га оно составляет1,80; 1,83 и1,90 % соответственно. Применение помета и компостов на его основе оказало влияние и на качественный состав гумуса. На контроле отношение СГК/СФК со-ставило 1,25, что свидетельствует о фульватно-гуматном типе гумуса. После внесения органических удобрений качество гумуса улучшалось (СГК/СФК1,47...1,79). Применение компоста (помет+ лузга) обеспечило максимальное содержание подвижных фракций гуминовых кислот, при одновременном повышении содержания стабильных фракций гуминовых кислот.

Published: February 2025

The present article considered a question about the self-treatment capacity of lakes, rivers and reservoirs in Akmola region based on oxygen indices. Furthermore, this study shows the influence of individual hydro-chemical indicators (sulfates, chlorides, magnesium, ammonium salt, nitrogen nitrite, fluorides, common iron, zinc, manganese, copper) on self-treatment capacity of water bodies. The self-treatment capacity of reservoirs in Akmola region was assessed based on oxygen parameters such as the amount of dissolved oxygen in water and the biological oxygen demand (BOD5). Rivers and lakes were divided into six classes of self-treatment ability. In addition, we studied the associated hydro-chemical components that can have impact on the purification potential of water in lakes and rivers. The results of research showed that the increased content of ammonium salt, nitrogen nitrite, total iron and copper suppress the self-treatmentcapacity of water. The majority of studied reservoirs by annual average indices have low self-treatment capacity. It was determined that the excess of the individual hydro-chemical components and the number of exceeding components with synergis-tic effect could have effect on the self-treatment capacity of water.

Published: February 2025

The article presents the results of studying rhinocytogram of the child population of three industrial cities of Karaganda region (Temirtau, Balkhash, Abai cities). The methods of cytological analyses of mucous membrane of the nasal cavity (MMNC) were used. Cytochemical methods were used for early detection of functional changes in the non-specific mononuclear system of protection of an organism from environmental factors. In the cytomorphologycal study of MMNC’s cell, it was found a reduced quantity of normal epithelial cells of children which live in Temirtau city (10.8 times) and in Balkhash city (12.1 times). Students of Abai city had the 13.3 times decrease of indicators in the cells of flat epithelium. The number of segmental and rod-core neutrophils with signs of damage exceeded the physiological norms in the children's population of Abai (4.8 times), Temirtau (6.3 times), and Balkhash (7.4 times). Thus, with the help of indica-tors of bacterial contamination of the mucous membranes of the nasal cavity, it is possible to identify people who are at risk for non-specific diseases and have suppressed function of immune system.

Implementation of Yolo (You Only Look Once) Algorithm for Drowsiness Detection as an Additional Safety Feature in the Operation of Crane Equipment in Real Time
Authors: Riza Adrian Maulana  , Hardiansyah
Published: February 2025

Work accidents, especially in the construction sector, are still a serious problem, with fatigue as one of the main causes. Based on data from satudata.kemnaker, the author realizes the need for early prevention solutions to reduce the risk of accidents due to fatigue. One of the approaches proposed is the development of an automatic detection system to recognize workers' facial expressions, especially in detecting levels of freshness and sleepiness. The obstacles that are often faced are limited time and scale in manual monitoring, especially on large-scale construction projects. To overcome this, the You Only Look Once (YOLO) algorithm is used, which is able to detect objects quickly and accurately, to provide continuous monitoring of workers' conditions. This research focuses on the application of the YOLOv8n model in an automatic freshness and sleepiness facial expression detection system. The model is trained using a dataset that includes a variety of facial expressions in different situations, allowing the system to detect worker conditions in real-time and at scale. The evaluation results in this research show very good performance, with precision reaching 99.9%, recall 100%, mAP50 99.5%, and mAP50-90 97.9%. Although the model sometimes makes mistakes in object class recognition, the overall results still show a very high level of accuracy. With this system, it is hoped that it can improve work safety through early detection of signs of fatigue in workers, so that the potential for work accidents can be significantly minimized.
INTERACTION OF 4-FLUOROPHENYLACETYLENE WITH TRIETHYLAMINE IN SOLUTIONS
Authors: Islam Sahidul , Barman Shrabani
Published: February 2025

In non-polar aprotic solvent cyclohexane, 4-Fluorophenylacetylene interacts with triethylamine in the excited state and forms a transient, emissive, weak bimolecular complex, known as exciplex. The fluorescence quenching of 4- Fluorophenylacetylene by triethylamine in cyclohexane is complex. In the lower range of triethylamine (which acts also as a quencher) concentration fluorescence quenching is predominantly dynamic and in higher concentrations the quenching phenomena is complicated. In polar protic solvent ethanol, the fluorescence quenching is dynamic throughout the entire range of quencher concentration, and the formation of exciplex is not observed.

MOLECULAR DOCKING STUDIES OF OXAZEPINE DERIVATIVES AGAINST CYCLOOXYGENASE-2 ENZYME AS POTENTIAL ANTI-INFLAMMATORY AGENTS
Authors: Addanki Aneesha , Nadendla Rama Rao
Published: February 2025

Non-steroidal anti-inflammatory drugs are widely used medications that reduce inflammation. It has been established that every inhibitor of the cyclooxygenase-2 enzyme exhibits anti-inflammatory activity. In this study, several oxazepine derivatives were designed and docked against the cyclooxygenase-2 enzyme to evaluate their antiinflammatory potential. The ligands were compared with conventional cyclooxygenase-2 inhibitors, such as valdecoxib and celecoxib. To elucidate the potential interactions between the inhibitors and the designed ligands, molecular docking simulations were conducted.The ligands were drawn in mol format using ChemSketch software. Avogadro software was then used to convert the ligands to .pdb format. The results of the molecular docking studies, conducted using iGEMDOCK software, were visualized using Discovery Studio Visualizer. The majority of the compounds demonstrated a greater binding affinity to the cyclooxygenase-2 enzyme. All of the ligands exhibited binding energies comparable to standard cyclooxygenase-2 inhibitors, such as valdecoxib (-91.8 kcal/mol) and celecoxib (-102.1 kcal/mol). The top two compounds, 7d (-109.2 kcal/mol) and 8h (-102.6 kcal/mol) were selected for display. Oxazepine derivatives show promise as a new class of anti-inflammatory drugs due to their stronger binding affinity to the cyclooxygenase-2 enzyme compared to conventional inhibitors.

Published: February 2025

An electrochemical sensor for the sensitive detection of Tamsulosin was fabricated by using a molecularly imprinted polymer layer of o-phenylenediamine on a gold electrode. The molecularly imprinted polymers were prepared by electropolymerization of o-phenylenediamine on the gold electrode. Square Wave voltammetry was used to investigate the electrochemical behaviors of the proposed sensor for Tamsulosin. A sigmoidal curve was obtained at 864 mV for Tamsulosin at the modified gold electrode. The anodic peak, which is due to the oxidation of the methoxy group on the phenyl ring of tamsulosin, showed a 10-fold enhancement on the gold electrode when modified with a polymeric film of o-phenylenediamine. The absence of a reduction peak for TAM in the reverse sweep establishes the irreversibility of the electrochemical process. Under optimal conditions, the peak current was linear to Tamsulosin concentration in the range of 8 × 10-7 M to 1 × 10-5 M, with a low detection limit of 7.4 × 10-8 M.

Published: February 2025

Customer advocacy has compelling evidence in the business sector that may influence prospective customers to purchase a company's products and services. It is a recommendation of a product, service, or brand based on its performance that spreads by word-of-mouth. The insurance penetration in Nigeria, which is less than 1%, reflects a lack of client advocacy for insurance. Disseminating favorable information based on user experience impacts purchasing decisions, leading to increased revenue and profitability. The present research seeks to determine the impact of Relationship Marketing (RM) characteristics on consumer advocacy. The study used a survey research design. The survey included 375,000 estimated insurance service consumers in Lagos State, Nigeria. A sample of 1,650 customers was picked from certain Local Government Areas in Lagos State using a non-probability sampling method. An adapted and validated questionnaire on relationship marketing and market penetration in the insurance industry was used. The Cronbach’s Alpha coefficient for the constructions varied from .76 to .90. One thousand six hundred fifty questionnaires were distributed, and 80% of them were completed and returned. The data were examined using descriptive statistics and multiple regression analysis for inferential statistics. The study indicates that relationship marketing has a substantial impact on customer advocacy in the insurance sector. The research recommends that insurance professionals use relationship marketing to impact customer advocacy in the insurance industry.

Published: February 2025

Marriage is a physical and mental bond between a man and a woman that aims to form a happy and lasting family. The bond of marriage is not merely to fulfill biological desires and lust but serves to continue offspring. This research aims to analyze the legal responsibility of the Head of Religious Affairs Office (KUA) and Penghulu in Sei Beduk Sub-district, Batam City towards same-sex marriage using fake identities. What is the legal status of such marriages and what legal efforts can be made as a solution. This research uses field study method with empirical juridical approach. Primary data is obtained from the Head of KUA and Penghulu in Sei Beduk Sub-district, Batam City. Secondary data were obtained from books, journal articles, theses, theses, and dissertations related to the research theme. The data were collected through interviews and documentation and analyzed using qualitative-inductive method. The results show that same-sex marriages are invalid when tested based on religious norms, and do not meet the requirements of the applicable laws and regulations. In terms of culture and noble values that live in the soul of the Indonesian nation, similar marriages are also seen as contradictory. As an effort of legal responsibility, the Head of KUA/Penghulu of Sei Beduk Subdistrict, Batam City as an interested party has made an application for annulment of marriage to the Religious Court of Batam City because he knows that there are defects in the pillars and conditions of marriage according to Islamic law and laws and regulations. In the decision of the Batam City Religious Court No. 60/Pdt.G/2013/PA.Btm, the same-sex marriage that took place at the KUA of Sei Beduk Subdistrict, Batam City was finally annulled, resulting in the status of the marriage being deemed never to have existed.
Financial Inclusion on the Nexus between Environmental Quality and Energy Consumption in Low-Income Sub-Saharan Africa
Authors: Olaoye Olugbenga O. , Bowale Ebenezer , Ewetan Olabanji O.
Published: February 2025

This study investigates how financial inclusion affects the connection between energy use and environmental quality in 20 low-income sub-Saharan African nations. The study employs annual secondary data from 1991 to 2022 with the cross-sectionally augmented autoregressive distributed lag (CS-ARDL) technique, which considers time dynamic, cross-sectional heterogeneity and cross-sectional dependence. The findings suggest that energy use significantly increases carbon emissions over the short- and long-terms, although financial inclusion has a positive yet statistically insignificant short-term effect on environmental quality. Furthermore, there is a positive correlation found between carbon emissions and real GDP and gross capital investment (GCI), which suggests that industrial expansion has occurred in African nations. Moreover, the study emphasizes how important financial inclusion is to sub-Saharan Africa's environmental quality. The policy recommendations urge policymakers in Sub-Saharan Africa to prioritize initiatives that enhance financial inclusion, promote green financing, support sustainable energy practices, strengthen environmental regulations, incorporate environmental considerations into economic policies, and foster regional cooperation for environmental management.

This study aims to study the long-term impact of energy consumption and trade openness on GDP per capita growth for the economy of Uzbekistan. The study was based on data from 1990 to 2023, and long-term relationships between variables were analyzed using VECM (Vector Error Correction Model). According to the results of the analysis, a 1 unit increase in energy consumption increased GDP per capita by 3.79 units, while a 1 unit increase in trade openness decreased GDP by 12 units. This situation shows that energy consumption is one of the main factors of the economic growth of Uzbekistan, but the negative impact of trade openness is mainly related to the high share of imports and low competitiveness of the national industry. According to the results of the analysis, to ensure the positive impact of trade openness on national economic growth, it is important to introduce policies aimed at developing national industry and improving energy efficiency. The research findings provide valuable recommendations for the effective use of energy resources for the country’s economy and the revision of foreign trade policies.

Moreover, this study also examines the environmental Kuznets curve (EKC) hypothesis. Thus, these two objectives make this study unique for Uzbekistan. This study determined cointegration through bounds test approach. Moreover, one can also capture short run and long run effects through this Bounds approach. The results of this study show that exports openness has a negative but insignificant effect on environmental degradation, whereas imports openness has a positive and significant effect on environmental degradation. These results demonstrate that negative effects of exports openness is not upsetting the deteriorating effect of imports openness therefore, it is concluded that trade is leading to environmental degradation in Uzbekistan. Additionally, the result of this study confirms EKC hypothesis in Uzbekistan.

This study investigates the interplay between oil price variations and stock market performance in Europe over the period 1991–2023. By analysing Europe as a cohesive economic entity, the research provides a unified view of how trends in energy markets and broader macroeconomic factors affect equity outcomes. The methodology combines ordinary least squares and quantile regression to robustly capture average impacts and variations across different segments of stock returns. Findings reveal that rising oil prices typically exert downward pressure on European equities by increasing production costs in petroleum-reliant industries. However, abrupt oil price shifts have nuanced effects: some segments exhibit heightened sensitivity, while others remain resilient, suggesting that adaptive industries may fare better than energy-intensive ones. Additionally, strong economic growth often intensifies fears of inflation, interest rate hikes, and market overheating, creating a negative association with stock performance. Inflation challenges equities, with higher-performing stocks especially vulnerable to price increases. The shift toward renewable energy appears to have short-term adverse effects, largely due to capital redistribution and transitional hurdles affecting traditional energy sectors. These results offer guidance for stakeholders. It underscores the need to align energy strategies with equity markets. Policymakers can enhance market resilience by addressing oil price volatility through transparency and risk mitigation, and by clearly communicating monetary policies to reduce inflation-induced uncertainty. While accelerating renewable adoption is vital for sustainability, careful management is needed to minimize disruptions to established sectors. Firms should hedge against energy price risks and invest in cleaner technologies to remain competitive in a changing landscape.

Published: February 2025

Ultisols and Spodosols are soils with contrasting properties - Ultisols are clay-rich while Spodosols are sand-dominated. Soil bulk density, which can limit fertility, is an important property needing improvement in these degraded soils. This study aimed to determine how applying biochar combined with liquid fertilizer affects the bulk density of these soils. The research design was a Randomized Complete Block Design (RCBD) with biochar application set as the research factor and length of biochar soaking in liquid organic fertilizer (LOF) set as the research block. Bulk density sampling occurred at three moisture levels - mornings, afternoons, and evenings after watering. Overall, the two soil types responded differently to biochar treatment. Immersion duration and moisture level at sampling did not significantly impact bulk density

A Prospective Study on Macular Thickness Changes Following Uncomplicated Cataract Surgery in Diabetic Patients Using OCT
Authors: Kumar Amrendra , Kumar Vidya Bhushan , Ambastha Anita
Published: February 2025

Background: Cataract surgery in diabetic patients often results in postoperative changes in macular thickness, potentially impacting visual recovery. Optical Coherence Tomography (OCT) provides a reliable means to monitor these changes. While previous studies suggest a temporary thickening of the macula after surgery, the extent and clinical significance of these changes remain unclear.
Aim: This study aimed to evaluate macular thickness changes following uncomplicated cataract surgery in diabetic patients using OCT and to identify any factors influencing the postoperative recovery process.
Methods: A prospective observational study was conducted on 100 diabetic patients undergoing uncomplicated cataract surgery. Macular thickness was measured using OCT preoperatively, and at one month and three months postoperatively. Data were analyzed using SPSS version 23.0, with paired t-tests to compare pre- and postoperative thickness values, and subgroup analyses to examine the impact of diabetes duration, age, and sex on outcomes.
Results: The mean macular thickness increased from 252 ± 20.3 microns at baseline to 264 ± 24.8 microns at one month postoperatively (p<0.01). By three months, the mean thickness decreased to 254 ± 22.7 microns, showing no statistically significant difference from baseline (p=0.18). No significant variations in thickness changes were observed across different age groups, sexes, or diabetes duration categories.
Conclusion: Macular thickening following cataract surgery in diabetic patients appears to be a transient phenomenon, peaking at one month and resolving by three months postoperatively. This self-limiting process does not seem to be influenced by age, sex, or diabetes duration.
Recommendations: Routine OCT imaging within the first postoperative month can help monitor macular changes in diabetic patients, facilitating early intervention if needed. Further studies exploring preventive strategies and their cost-effectiveness are recommended.
Keywords: Diabetes, cataract surgery, macular thickness, optical coherence tomography, postoperative changes
A Comparative Study of DMF Index and ICDAS in Pediatric Caries Monitoring
Authors: Wang Shiyu , Ni Jing
Published: February 2025

Dental caries remains a prevalent oral health issue globally, significantly affecting children's health and overall well-being in the United Kingdom. Despite improvements over the past two decades, caries continues to be the most common oral disease among children, impacting their physical and psychological health, as well as their academic performance. Effective monitoring and assessment of dental caries are crucial for the development of preventive strategies and public health initiatives. This study compares the Decayed, Missing, and Filled (DMF) Index and the International Caries Detection and Assessment System (ICDAS) in the context of UK children's oral epidemiological surveys. Key aspects such as cost, feasibility, examination time, training requirements, and the value of collected data are analyzed to evaluate the advantages and limitations of each system. The findings suggest that while the DMF Index is a cost-effective, straightforward tool suitable for large-scale epidemiological assessments, ICDAS provides a more detailed and nuanced evaluation of carious lesions, particularly beneficial for early detection and prevention in smaller, focused studies. The study concludes that the DMF Index is better suited for broad epidemiological surveys in the UK due to its practicality and simplicity, while ICDAS is more appropriate for detailed clinical research aimed at early caries prevention.

Published: February 2025

The rapid development of MOOC construction has brought a teaching reform to both higher vocational education and general higher education. However, the construction practice of MOOC for higher vocational colleges is different from that of general universities due to their different types of personnel training. On the basis of an investigation of MOOC and a survey of the participants of MOOC, this paper points out that MOOC construction in higher vocational colleges should take into consideration of the characteristics and realities of higher vocational education and have its own uniqueness. The characteristic of MOOC in higher vocational education is analyzed and some suggestions for MOOC construction are proposed. The construction mode of MOOC is also studied taking a professional core course — Construction and Maintenance of Railway Subgrade in the program of Railway Engineering Technology as an example so as to provide some reference for the current MOOC construction.
