Published: December 2024

Objective: Compare nutrient intake based on categories of disordered eating behaviors in adolescents. Materials and methods: The present study has a non-experimental cross-sectional analytical design, with a quantitative approach. Sampling was carried out at convenience. The brief questionnaire of risky eating behaviors used by Padrós-Blázquez et al. was used, and weight and height were determined to form the body mass index. The 24-hour reminder dietary survey was also applied to calculate the percentage of adequacy and determine nutrient intake, the percentages of adequacy (%AD) were calculated, and the nutrient ranges were taken according to the Recommended Dietary Allowances (RDA), for sugar the recommendation of the Nutrition Committee of the European Society of Pediatric Gastroenterology, Hepatology and Nutrition was used. An overadequate AD was considered when the %AD was >110%, adequate with a range of 110 - 90%, low <90%.
Results: A combined prevalence of risky eating behaviors of 37.88% was found, with medium and high risk (25.76% and 12.12% respectively). A significant difference was found in the intake of vitamin A, ascorbic acid, iron, and folate among the categories, being higher in the low-risk group compared to the medium and high-risk groups. Additionally, overadequate %ADs were found for sugar, energy, protein, potassium, sodium, and carbohydrates, while the lowest %ADs were for folate, fiber, and phosphorus. Conclusions: Nutrient intake differs according to the REB category, and key micronutrients for adolescence are involved in low intake, which can cause negative health effects.

Latarge surgery has proven to be an effective stabilizing operation for recurrent anterior dislocation of the shoulder joint. One of the complications that can hinder good functional postoperative results is graft resorption. At the moment, the factors influencing the intensity of this process and how osteolysis can be prevented are not entirely clear. This article presents a new technique for quantifying graft resorption after Latarge surgery, which will allow predicting the outcomes of remodeling, correcting rehabilitation and, in the future, actively influencing the processes of graft osseointegration.

Authors:   Volgograd State Medical University, Pushkarskaya L.S. , Kozhanov A.V. ,   Volgograd State Medical University
Published: December 2024

Seizar (lamotrigine) is an approved treatment for bipolar affective disorder that has shown significant results in maintenance therapy and prevention, yet it remains underappreciated in russian psychiatry. Primarily, the controversy over lamotrigine prescribing is related to its side effect profile – namely, risks of potentially dangerous rash. The aim of this review is to analyse the efficacy of the drug, its side-effect profile and frequency of side-effects, and to compare it with other pharmacotherapies. We made a literature review of russiam and foreign databases. Seizar shows a good safety and efficacy profile, improving patients’ quality of life in the long term and halving the recurrence rate. The risk of rash in 8% of patients within 4 months of treatment initiation is associated with uncorrected drug titration, combination with valproate; however, these risks must be compared with the much more common risks associated with untreated BD.

A prototype of an automated laser system (0,81 μm) was tested with a laser power from 100 to 300 mW using the fundus eye model. We studied the time of formation of coagulates with a brightness from 5 to 70 % of the background level, their homogeneity, and the correspondence of the planned and actual brightness of the coagulates. To obtain coagulates with a brightness of 5–10 % of the background level (grade 1 according to L’Esperance), the most optimal laser power is from 100 to 180 mW: the time of coagulate formation did not exceed 100 ms, brightness variability is less than 7,5 %. Laser power in the range from 200 to 300 mW is optimal when obtaining coagulates with a brightness of 20–40 % and 50–70 % of the background level (grades 2 and 3 according to L’Esperance): the time of coagulate formation in the range of 100–250 ms, brightness variability less than 4 %. The greatest correspondence between the actual and planned brightness of coagulates for the brightness range of 5–70 % of the background level was found at a laser power of 140–180 mW.

The study included 196 patients (250 eyes) with overmature cataracts. The patients were divided into 2 groups (125 eyes in each group). In all patients, the type of overmature cataract was determined intraoperatively using I-OCT integrated into the operating microscope [Hi-R NEO (HAAG STREIT, Germany)]. In the first group, femto-support for cataract surgery was performed according to a developed algorithm with optimized parameters of femtolaser exposure depending on the type of overmature cataract according to I-OCT data, in the second group, femto-support was performed using a standard method. When using the developed algorithm with optimized parameters of femtolaser exposure in comparison with femtoassistance, performed according to the standard method, the frequency of incomplete femtocapsulotomy at 2 (2.5 % vs 17.4 %, respectively) and 3 (4.9 % vs 21.6 %,respectively)) types of overmature cataract according to I-OCT data, as well as the frequency of capsulorhexis escape in type 3 (2.4 % vs 16.2 %, respectively) were statistically significantly lower in the first group of patients. The developed algorithm with optimized parameters of femtolaser exposure at the stage of anterior capsulorhexis, taking into account the type of overripe cataract according to intraoperative OCT data, ensures high quality of this stage of surgery and expands the possibilities of practical application of femtolaser support for cataract surgery in complicated cases.
Apoios e interesses nos discursos proferidos durante a audiência pública da ação direta de inconstitucionalidade do decreto N.º 10.502/2020
Authors: Horta Ícaro Belém , Torres Josiane Pereira
Published: December 2024

Desde 2008 a perspectiva inclusiva vem se consolidando no Brasil, tendo marco na Política Nacional de Educação Especial na Perspectiva da Educação Inclusiva (PNEEPEI). Com o impeachment da presidenta Dilma, houve uma mudança nesse cenário. No ano de 2020, Bolsonaro estabelece o Decreto n.º 10.502, instituindo a nova política (PNEE), reforçando a segregação. Tal ação mobilizou grupos sociais para a suspensão do Decreto, gerando a Ação Direta de Inconstitucionalidade (ADI) 6590. Em 2021, o Superior Tribunal Federal realizou uma Audiência Pública sobre a constitucionalidade do Decreto. Com essa repercussão, suscita-se a questão: quais os interesses implícitos e explícitos nos discursos proferidos na Audiência Pública da ADI 6590 pelos atores contrários e favoráveis à PNEE? Para tal, utiliza-se da metodologia de pesquisa qualitativa com base documental, tendo como fonte de dados as transcrições dos discursos da Audiência, processado pelo software NVivo 14 para organização e categorização. As concepções de inclusão escolar propostas por Jannuzzi (2004b) e de deficiência, por Leite e Lacerda (2018) e de Torres, Cruz e Cabral (2021), embasaram o estudo que delineou um panorama das percepções sociais e políticas, revelando diferentes interesses. Com essas concepções, emerge um grupo favorável à constitucionalidade, com a presença de instituições alinhadas ao governo Bolsonaro e de instituições privadas e especializadas; do outro lado, os contrários a constitucionalidade, representados por membros do direito, pesquisadores, organizações políticas, sociais e de pessoas com deficiência. Analisou-se interesses implícitos na defesa do Decreto, especialmente no que reforça o encaminhando dos estudantes PAEE para as instituições especializadas
Seletividade policial
Authors: Sena Camila Luiza de
Published: December 2024

Este trabalho tem como objetivo identificar os sentidos atribuídos à prática de abordagem policial em Belo Horizonte, Minas Gerais (MG), no que se refere às mulheres envolvidas no crime, especificamente no tráfico de drogas. Inicialmente, foi realizada uma revisão bibliográfica sobre abordagem policial e a construção da fundada suspeita. Metodologicamente, foram conduzidas entrevistas semiestruturadas com policiais militares atuantes em Belo Horizonte. Os resultados indicam que a construção da fundada suspeita incorpora um elemento subjetivo, fundamentado nos valores e crenças dos policiais. Além disso, destaca-se que a abordagem às mulheres é mínima devido a essas mesmas crenças e valores, assim como às expectativas sobre as consequências institucionais e o impacto que a abordagem a mulheres pode ter na carreira dos policiais.

Published: December 2024

Puberty is a normal developmental process in which a child develops into a biologically and/or sexually mature adult. Even though puberty is a natural event, it is not uncommon for children to be confused or worried about puberty. Therefore, using the Participatory Action Research Method, this community service aims to increase knowledge about puberty in boys in the Sambikerep sub-district, Surabaya. The activities include health promotion, education, and free circumcision for the children by surgeons and medical students from the School of Medicine, Universitas Ciputra Surabaya. Statistical analysis of knowledge before and after health promotion used the Wilcoxon test in SPSS version 26 with a significance limit of p < 0.05. The overall community service activities ran quite smoothly; there were 24 children who took part, with the number of children getting a pre-test score < 75 points as high as 29.2%. However, no children got a post-test score of < 75 points after the health promotion. The median score of knowledge about puberty before and after health promotion was 75 (12.5–100) and 100 (87.5–100) points, respectively (p-value <0.001). Through this community service, health promotion and education about puberty must be continuously provided to pre-pubertal boys so that they have a good understanding of puberty and make healthy decisions related to their sexual and emotional health.

Children with cancer in India: An ethical framework for practice
Authors: Bagai Poonam , Kanwar Vikramjit S , Carnevale Franco A , Macdonald Mary Ellen , Singh Arora Ramandeep
Published: December 2024

Background: Childhood cancer has been ranked the most common cause of death due to non-communicable disease among 5- to 14-year-old children in India. Ethical concerns have been identified in the care of children with cancer in India, yet there is a paucity of ethical standards for clinical practice to help address these concerns. For example, emerging research has demonstrated that many children are distressed when they are impeded from participating in discussions and decisions regarding their cancer care. Therefore, we sought to create an ethical framework to guide practice with this population.

Methods: We developed this ethical framework by conducting (a) a normative analysis of relevant documents that articulate norms for healthcare providers working with children in India and (b) stakeholder consultations with childhood cancer survivors, parents, and clinicians.

Results: The ethical framework is structured according to twelve key ethical principles and corresponding challenges or implications for clinical practice. We discuss how this ethical framework can help address three leading ethical concerns that we have identified within the care of children with cancer in India: (a) communication problems; (b) inadequate care of symptoms or promotion of comfort; and (c) injustices or inequities related to limited financial means or poverty.

Conclusion: Ethical concerns that have been related to the care of children with cancer in India can be prevented or at least mitigated through the integration of this ethical framework in everyday clinical practice.
Narrative Review and Perspective: The State of Art and Emerging Opportunities of Bioprinting in Tissue Regeneration and Medical Instrumentation
Authors: Halper Jaroslava
Published: December 2024

3D printing was introduced in the 1980s, though bioprinting started developing a few years later. Today 3D bioprinting is making inroads in medical fields, including production of biomedical supplies intended for internal use, such as biodegradable staples. Medical bioprinting enables versatility and flexibility on demand and is able to modify and individualize production using several established printing methods. A great selection of biomaterials and bioinks is available, natural, synthetic and mixed; they are biocompatible and non-toxic. Many bioinks are biodegradable and they accommodate cells so upon implantation they integrate within the new environment. Bioprinting is suitable for printing of tissues using living or viable components, such collagen scaffolding, cartilage components, cells, and also for printing parts of structures, such as teeth, using artificial, man-made materials that will become embedded in vivo. Bioprinting is an integral part of tissue engineering and regenerative medicine. The addition of newly developed smart biomaterials capable of incorporating dynamic changes in shape depending on the nature of stimuli led to adding the 4th dimension of time in the form of changing shape to the three static dimensions. 4D bioprinting is already making significant inroads in tissue engineering and regenerative medicine, including new ways to create dynamic tissues. Its future lies in constructing partial or whole organ generation.

Authors: Li Xiang , Wang Yikan
Published: December 2024

The advent of e-government platforms has highlighted the pressing need to enhance the accessibility of digital services for individuals with low literacy rates and special needs. The objective of this study is to design and develop an adaptive interface system utilising deep learning technology with the intention of markedly enhancing the accessibility and user-friendliness of e-government platforms, particularly for users with low literacy rates and special needs. The proposed model incorporates multimodal learning and reinforcement learning mechanisms, enabling automatic adjustments to the interface layout, text size, colour contrast and voice assistance functions to align with the personalised requirements of users. In particular, when integrated with sentiment analysis and speech recognition modules, the system is capable of identifying and predicting the user's operational intent in real time, thereby enabling dynamic interface adjustments. The model's innovative aspect lies in its adaptive adjustment capability and high efficiency in low-resource environments. The experimental results demonstrate that the proposed model can markedly enhance the operational efficiency and satisfaction of individuals with low literacy rates and special needs, while also improving the user experience.

Published: December 2024

Objectives: This retrospective cohort study aimed to compare and evaluate the 1-year stability of two Korean implant brands, Osstem and Toplan, both treated with alumina sandblasting and acid etching (SA) surface modification. Methods: This retrospective analysis evaluated patients with American Society of Anesthesiologists grade I or II, >20 years, with alveolar bone volume suitable for implant placement, who received immediate or delayed placement after extraction, and with Osstem (n=57) or Toplan (n=87) implant. The insertion torque value (ITV) measured on the day of implant placement and the implant stability quotient (ISQ) measured on the day of implant placement, 1 month post-surgery, and 2–3 months after implantation were analysed. Results: Both implants had significantly increased ISQs over time, and the ISQs did not significantly differ between Osstem and Toplan implants at any time point. Osstem implants showed significantly higher ISQs in D2 than in D3 bone, and in the mandible than in the maxilla at all time points. Toplan implants with diameter >4.0 mm showed higher initial ISQs. Osstem implants showed significant correlation between ITV and ISQ on the day of placement (r=0.349, p<0.01), but not at later time points. For Toplan implants, no significant correlation was confirmed between ITV and ISQ at any time point. At 1-year follow-up, both implants were still providing functional service. Conclusion: Osstem and Toplan implants with SA surface treatment showed a high level of stability for 1 year, and no significant difference in stability was observed between the two implants. Both implants are considered clinically reliable products.

The Concept of Contradictory Hadiths According to Allama Shabbir Ahmad Usmani (may Allah have mercy on him) in light of His Book Fath ul Mulhim Sharh Sahih Al-Imam Muslim (may Allah have mercy on him)
Authors: Ali Fawad , Amin Dr.Ismail Muhammad
Published: December 2024

This article examines the methodology of Allamah Shabbir Ahmad Usmani(R.A) in addressing conflicting Ahadith and reconciling apparent contradictions in the Prophetic traditions, as seen in his book Fath al-Mulhim. Usmani’s approach closely aligns with the established methodology of the majority of Hadith scholars, following a structured framework. He prioritizes reconciling conflicting narrations to ensure all evidence is utilized without disregarding any part of the Sunnah. When reconciliation is not possible, he examines the possibility of abrogation by identifying the nasikh (abrogating) and mansukh (abrogated), giving precedence to the nasikh if abrogation is proven. In cases where neither reconciliation nor abrogation is possible, he resorts to preference, weighing one Hadith over the other based on its alignment with the Qur'an, Sunnah, or established principles of Islamic jurisprudence (qiyas).The study reveals that Allamah Usmani consistently applies this methodology, demonstrating a commitment to preserving the integrity of the Sunnah while ensuring his conclusions align with the broader objectives of Islamic law. Usmani's approach reflects the traditional framework upheld by Hadith scholars and underscores the need for a systematic methodology in addressing contradictions in the Sunnah.This study highlights the continued relevance of classical Hadith methodologies in contemporary Islamic scholarship, offering a model for scholars and students to approach conflicting narrations with precision and adherence to traditional principles, ensuring accurate application of the Sunnah in various fields of Islamic knowledge.

The decreasing well-being among doctoral candidates, coupled with a high prevalence of distress problems, is a topic of increasing concern in the field of higher education and research policy. The present study aimed to replicate, implement, and evaluate the effectiveness of The Third Half, a multi-component psychoeducational program in doctoral students. To address the limitations of the pilot study, we conducted a non-randomized controlled study using a repeated measures pre-post design with a total of 97 participants (Mage = 32.5; SD = 8.23), of whom 26 participated in the experimental group. Results showed that Third Half program participants reported significant decreases in indicators of negative affect (F = 4.01; p = .04) and anxiety (F = 4.95; p = .02) compared to the general control group; in the matched sample analysis (n = 20) significant decreases were found in indicators of negative affect (F = 4.72; p = .03), anxiety (F = 4.09; p < .001), and depression (F = 4.95; p = .03). It is concluded that the Third Half program is an effective and implementable psychoeducational program to improve the skills of early-career researchers in wellness management.
“De obra y pintura moderna y romana”. Identidades y experiencias artísticas de los maestros pintores del entorno de los Mendoza en la Castilla finisecular del Cuatrocientos
Authors: Romero Medina Raúl
Published: December 2024

El presente articulo reflexiona sobre las identidades y las experiencias artísticas de los maestros pintores que trabajaron en el entorno de la familia Mendoza en una Castilla finimedieval. Un periodo de gran complejidad donde la biografía de muchos de estos maestros se encuentra tan desdibujada como su perfil profesional o su vinculación con unas obras dispares en ámbitos geográficos. Un análisis que, apoyado en nuevas fuentes documentales o revisitando otras ya conocidas, aporta nueva luz sobre personalidades tan controvertidas como la del pintor Juan (Rodríguez) de Segovia.

Resulta imposible encuadrar la producción de Paloma de la Cruz (Málaga, 1991) en una única disciplina artística. Su obra difumina los límites establecidos entre escultura, artesanía, dibujo, arquitectura, instalación e incluso performance. Sus innovadores y vanguardistas procedimientos de creación le han concedido, además de numerosos reconocimientos, un merecido espacio en las colecciones del Centro de Arte Contemporáneo de Málaga, del Genalguacil Pueblo Museo y de la Diputación de Cáceres, entre otros. En el presente artículo se abordará, no sólo el contenido, mensaje y forma de su obra, sino también un recorrido por las fuentes bibliográficas y digitales existentes actualmente para el estudio académico de esta prometedora artista andaluza.

Due to the low porosity and permeability of the shale matrix, multi-fractured horizontal well (MFHW) is one of the most well-known technologies to promote the withdrawal of shale oil. It is a great challenge to characterize the flow behavior by coupling pre-Darcy flow in pores of the shale matrix and Darcy flow inside fractures, particularly in the radial composite shale reservoir with stimulated reservoir volume (SRV). Because the semi-analytical method can contribute to revealing the flow mechanism of the MFHW, the approach to efficiently obtain a suitable and exact semi-analytical solution becomes a key issue. In this work, to couple the modified point-source solution of the shale matrix with the numerical solution of fractures,we developed a semi-analytical solution to analyze the impact of pre-Darcy flow and SRV properties on the pressure behavior of the MFHW. Moreover, we used a local grid refinement method to verify the accuracy of the newly developed semi-analytical solution. The results show that the radial flow regime in the dimensionless pressure derivative will obviously disappear due to the pre-Darcy flow. Pre-Darcy flow in the SRV zone is adverse to the late production of the MFHW after the pseudolinear flow regime, while pre-Darcy flow in the unstimulated reservoir volume (USRV) zone is beneficial to increase the production during the regional interporosity flow regime. Meanwhile, the “groove” can be recognized from the pressure derivative curves, which mainly depend on the mobility ratio and the storage capacity ratio. In addition, due to the uneven distribution of fractures, the pressure derivative during the pseudoradial flow regime significantly deviates from 1/(2N).
Completion Design Optimization as a Function of Reservoir Quality in Tight Reservoirs: A Big Data Approach
Authors: Moussa Tamer , Dehghanpour Hassan
Published: December 2024

Over the past decade, more than 40,000 multifractured horizontal wells (MFHWs) were completed in the Western Canada Sedimentary Basin (WCSB), making Canada the third largest oil exporter in 2022. However, this process consumed more than 56 billion gallons of water, with more than 30 billion gallons unrecovered—equivalent to the annual water consumption of a city of 1 million for nearly 5 years. This raises concerns about water use efficiency in fracturing operations. Can big data mining reveal the relationship between reservoir quality, fracturing design parameters, and process efficiency? This research aims to develop a hybrid analytical and machine learning (ML) workflow to optimize completion design as a function of reservoir quality in tight reservoirs.

To achieve this objective, we analyze data from more than 14,000 wells in the Montney formation. Using core analysis and well log data, we develop a support vector machine (SVM) to predict permeability and a fuzzy clustering model to estimate fracturability. We categorize Montney’s lithology through hierarchical clustering. With 3D kriging interpolation, we fill missing data and create high-resolution 3D petrophysical maps, which help derive a reservoir quality index (RQI) map to identify the sweet spots for completing new wells. We introduce a stage placement efficiency (SPE) metric to evaluate fracture stage placements in-line with the RQI. Finally, we develop neural network–based proxies that predict well performance based on reservoir quality, geomechanical properties, and completion design, incorporating more than 40 completion parameters, the RQI, and historical production data.

The results reveal a higher degree of homogeneity in the upper Montney compared to the middle and lower segments. Generally, completion design parameters significantly impact MFHW productivity more than formation characteristics. Applying the proposed proxy to Montney-oil MFHWs could increase fracturing water recovery by 94.4%, reduce injected water volume by 22%, and boost cumulative oil production by 37.9%. The proxy aims to enhance fracturing water efficiency. A 1% reduction in freshwater consumption in the WCSB could save more than 100 million gallons of fresh water and cut CO2 emissions by up to 2,000 tons, equivalent to removing more than 1,000 gasoline cars from Canadian roads.
Numerical Simulation Study of 3D Crosswell Measurement for Hydraulic Fracture Zone Diagnostics in Steel-Cased Boreholes

Published: December 2024

Electrical signals in the vicinity of excited steel-cased borehole sources offer significant potential for monitoring fracture zones filled with highly conductive proppant. However, despite this potential, it is difficult to accurately monitor fracture zones in steel-cased boreholes due to various challenges, such as interference from background noise and the complexity of the geological environment. To address these challenges, we propose a novel crosswell measurement method specifically designed for diagnosing hydraulic fracture zones in steel-cased boreholes. During dynamic monitoring of fracturing, high-power direct current (DC) is applied to the steel-cased borehole, and the potential on the other open borehole is measured. This method uses a 3D finite element algorithm to establish a fracture detection model, and its accuracy has been verified by comparing the results with a benchmark model. Furthermore, the relationships between the geometric parameters of both fracture zones and boreholes, and the obtained measurement signals, are investigated. To evaluate the effectiveness of our proposed method in complex underground conditions, a case study is conducted. Numerical results indicate that the measurement signals are highly sensitive to a fracture’s size, thickness, and conductivity but less so to its shape. Moreover, whenever feasible, minimizing the distance between the measurement line and the asymmetrical fracture zone is essential for improving signal quality. In a case study focusing on segmented-fracturing monitoring, the signal difference observed before and after hydraulic fracturing clearly reveals the orientation of fracture zones during the fracturing process. This study demonstrates that the crosswell measurement method is an effective technique for dynamically monitoring hydraulic fracturing in steel-cased boreholes and holds promising applications.
