Published: February 2025

Aims
Diabetic foot ulcers have caused significant medical, economic and social consequences for patients, families and society. With appropriate treatment, many diabetic foot ulcers can heal, temporarily avoiding possible amputation. Unfortunately, even if foot ulcers subside, recurrence is still common. The recurrence of ulcer has brought another physical and psychological trauma to diabetic foot patients who yearn for a better life. Therefore, it may be more useful to evaluate the factors associated with ulcer recurrence in diabetic foot ulcer patients.

Methods
The PubMed, Web of Science, Embase and China National Knowledge Infrastructure databases were comprehensively searched for prospective or retrospective studies published up to February 1, 2024. All English or Chinese language studies on diabetic foot ulcer patients who experience recurrence were included, and RevMan 5.3 software was used to analyze the data.

Results
A total of 22 studies meeting the eligibility criteria were ultimately included in this meta-analysis. 1861 of 5252 diabetic foot ulcer patients experienced recurrence during follow-up. The following variables were associated with an increased risk of ulcer recurrence: male (OR = 1.26, 95% CI = 1.10 ~ 1.44, P = 0.0009), smoking history (OR = 1.18, 95% CI = 1.04 ~ 1.35, P = 0.01), living alone (OR = 1.86, 95% CI = 1.21 ~ 2.86, P = 0.004), plantar ulcers (OR = 2.44, 95% CI = 1.41 ~ 4.23, P = 0.001), diabetic retinopathy (OR = 1.59, 95% CI = 1.35 ~ 1.88, P < 0.00001), diabetic nephropathy (OR = 1.37, 95% CI = 1.12 ~ 1.68, P = 0.002), diabetic peripheral neuropathy (OR = 1.78, 95% CI = 1.45 ~ 2.19, P < 0.00001), foot deformity (OR = 2.51, 95% CI = 1.85 ~ 3.40 P < 0.00001) and peripheral arterial disease (OR = 3.10, 95% CI = 2.43 ~ 3.95 P < 0.00001). However, hypertension (OR = 1.16, 95% CI = 0.96 ~ 1.40, P = 0.13) and body mass index (MD = 0.20, 95% CI = −0.12 ~ 0.53, P = 0.22) were not associated with diabetic foot ulcer recurrence.

Conclusions
Our meta-analysis identified the following important risk factors for diabetic foot ulcer recurrence: male sex, smoking history, living alone, plantar ulcer, diabetic retinopathy, diabetic nephropathy, diabetic peripheral neuropathy, foot deformity, and peripheral arterial disease. Understanding these factors and their impact on ulcer recurrence is crucial for multidisciplinary teams to develop management and treatment plans for diabetic foot ulcer patients.

Published: February 2025

Purpose
Hyponatremia is the most common electrolyte disorder, with potentially serious consequences. Studies validating hyponatremia used as a principal diagnosis are lacking. Studying principal diagnoses is important since it indicates the main reason for inpatient care. The aim of this study was to assess the validity of principal diagnoses of hyponatremia according to the International Classification of Diseases, tenth revision (ICD-10) in patients discharged from hospital.

Methods
Three independent reviewers retrospectively analyzed medical records of 428 hospitalized patients, ≥18 years old, discharged with a principal diagnosis of either hyponatremia or syndrome of inappropriate anti-diuretic hormone secretion (SIADH) from three different hospitals during 2014–2017. The positive predictive value of hyponatremia as a principal diagnosis was calculated.

Results
The median age of the studied population was 73 (IQR 64–81) years and 69% were women. The range of sodium levels was < 100 to 139 mmol/L. The mean sodium level was 119 mmol/L. Of the patients 27% were treated in an intensive care unit (ICU)/high dependency unit (HDU). Hyponatremia was deemed to be the principal cause of inpatient care in 411 out of 428 patients, corresponding to a positive predictive value for hyponatremia as a principal diagnosis of 96% (CI 95% 94–98).

Conclusions
The current study showed that 19 diagnoses out of 20 were correct implying a high validity. Thus, a principal diagnosis of hyponatremia, appears to be a useful measure in clinical and epidemiological studies aiming to target a clinically relevant consequence of hyponatremia in hospitalized patients.
A representação dos corpos gordos em animações infantis

Published: February 2025

O corpo é um elemento de expressão cultural que carrega marcas da sociedade da qual faz parte. Ele ocupa um papel central na representação da subjetividade, processo mediado pelo discurso, entendido, neste artigo, como uma dimensão da prática social. A partir de tais pressupostos, o presente trabalho busca fazer uma investigação, embasada na Análise de Discurso Crítica (Chouliaraki; Fairclough, 1999; Fairclough, 2003), das representações dos corpos gordos nas animações das princesas da Disney. Ainda, objetiva levantar relações entre os estereótipos fomentados pelos discursos midiáticos e a construção identitária desses sujeitos na sociedade contemporânea. Para tanto, realizou-se a análise através das três funções apontadas por Fairclough (2003) – representacional, identificacional e acional. A análise evidencia que os discursos da indústria cinematográfica constroem e reforçam estereótipos, sobretudo de gênero e de beleza. Os personagens das animações infantis da Disney que estão fora do padrão de magreza representam apenas figuras secundárias e/ou fortalecem preconceitos sociais.

Abstract
In this paper, X1 and X2 (two different xylanases), were employed to pretreat oxygen-delignified kraft softwood pulp. X2 could handle unwashed pulp, while X1 needed washed pulp. Subsequently, the effects of two xylanases on the physical properties, microstructure and fiber characteristics of pulp were investigated. Compared to the ECF bleached pulp (OD0EpD1), the brightness (86.9 %ISO), tensile index (28.4 N·m/g) and burst index (1.67 kPa·m2/g) of the ECF bleached pulp treated with X2 xylanase (9 U/g) increased by 2.4 %ISO, 4.8 % and 24.6 %. After X2 xylanase pretreatment, the fiber length of pulp decreased slightly, the content of fine fibers increased, and the water retention value increased. Due to the pretreatment of X2 xylanase, some non-fibrous components and chromophores in the pulp were removed, and the intrinsic viscosity and average molecular weight of the pulp were reduced. The crystallinity of cellulose decreases by 1 %, the fiber surface becomes rough, and voids are created, the specific surface area increases, and the average pore size increases. These findings suggest that enzyme pretreatment is a green and highly effective approach that not only significantly enhances pulping performance but also demonstrates excellent adaptability to complex processing environments and it streamlines the traditional pulping process effectively.

Abstract
Planned oocyte cryopreservation (POC) has become widely available, allowing women to circumvent age-related fertility decline. The aim of our study was to examine whether women who have undergone POC were able to correctly predict the chance of having a child with their cryopreserved oocytes. We conducted a telephone survey with 260 women who underwent POC at our center between January 2017 and December 2023. Participants were asked to estimate their chance of having at least one live birth in case they would use their cryopreserved oocytes. For each participant, we also calculated the chance of achieving at least one live birth based on her age at the last oocyte retrieval and the number of cryopreserved oocytes, according to a model published by Goldman and colleagues in 2017. The median estimated probability of achieving a live birth was 50%, while the median calculated probability was 75% (P < 0.001). Only 28.1% of the participants accurately estimated their chances. In conclusion, a large percentage of women undergoing POC underestimate the probability of achieving a live birth if they use their cryopreserved oocytes. Improved counseling is essential to provide comprehensive information about the probability of live birth and prevent women from undergoing unnecessary treatments.

Lay summary
More and more women choose to freeze eggs in order to circumvent age-related fertility decline. In this study, we asked women to estimate their chance of having a child if they used their frozen eggs in the future. For each patient, the chance was also calculated based on a model taking into account the number of eggs she had frozen and her age during egg freezing. Surprisingly, women estimated their chance of having a child as being lower than it actually is. Our results highlight the importance of providing patients with clear information about treatment success to prevent them from undergoing unnecessary additional treatments.
ОЦЕНКА ГАЗОКИНЕТИЧЕСКИХ ХАРАКТЕРИСТИК УГОЛЬНОГО ПЛАСТА ПО ДАННЫМ ИЗМЕРЕНИЯ ТЕРМОДИНАМИЧЕСКИХ ПАРАМЕТРОВ В ГЕРМЕТИЧНОЙ ЕМКОСТИ С БУРОВЫМ ШТЫБОМ

Теоретически обоснован и с использованием данных натурных измерений апробирован метод определения газокинетических характеристик угольного пласта: газоносности, коэффициентов диффузии, массообмена и скорости десорбции, что необходимо при разработке технологий выемки залежей угля и утилизации метана. Метод основан на решении обратной задачи в рамках нелинейной модели эмиссии газа из частицы, помещенной в изолированную емкость, по изменению во времени термодинамических параметров (давления и температуры) в герметичной емкости с буровым штыбом. Анализ модели показал, что отношение концентраций метана в емкости в различные моменты времени не зависит от газоносности. Это дает возможность разработать и численно реализовать двухэтапный алгоритм: сначала из решения обратной коэффициентной задачи определяются коэффициенты диффузии, массообмена и скорости десорбции, затем с минимизацией специальным образом построенного функционала - газоносность. Натурные данные получены с использованием штыба при бурении шпура на одной из действующих шахт Кузбасса посредством измерения давления и температуры в пяти емкостях в течение 10 сут. Их интерпретация позволила оценить остаточное содержание метана на исследуемом участке пласта - 4 кг/м3.
The authors theoretically substantiated and, using in-situ measurements, proved the method of determining kinetic characteristics for coal bed gas: content, diffusion factor, mass exchange and rate of desorption. These data are required for the development of technologies of coal mining and methane utilization. The method involves solution of an inverse problem within the framework of a nonlinear model of gas emission from a particle placed in an isolated container, using the data on time change in thermodynamic parameters (pressure and temperature) in a sealed canister with coal chippings. The model analysis shows that ratio of methane concentrations at different moments of time is independent of gas content. This enables development and numerical implementation of a two stage algorithm: first, by solving an inverse problem with time-dependent coefficients, the factors of diffusion, mass exchange and desorption are found; then, with minimization of a special function, the gas content is determined. The in-situ data are obtained using coal chippings from drilling in an operating mine in Kuzbass, by means of measurement of pressure and temperature in five canisters for 10 days. The interpretation of the data made it possible to assess the methane content in the test coalbed site as 4 kg/m3.
ПОТЕРЯ НЕСУЩЕЙ СПОСОБНОСТИ ПЕСЧАНОГО ОСНОВАНИЯ ТЯЖЕЛОЙ КОЛОННЫ И ЗАГЛУБЛЕННОЙ В СЫПУЧУЮ СРЕДУ ПЛАСТИНЫ ПРИ МНОГОКРАТНЫХ СЛАБЫХ УДАРНЫХ ВОЗДЕЙСТВИЯХ

Published: February 2025

Приведены результаты экспериментов и численных расчетов по исследованию устойчивости тяжелой колонны, установленной на поверхности сыпучей среды, и заглубленной пластины. Колонна и пластина нагружались допредельной статической нагрузкой. На сыпучую среду воздействовали многократными слабыми ударами. В лабораторных экспериментах установлено, что при таких нагружениях сыпучая среда постепенно эволюционирует к критическому состоянию и происходит потеря сдвиговой прочности. Скорость приближения к критическому состоянию растет с увеличением числа ударов. Критическое число ударов до разрушения среды подчиняется логнормальному распределению. Наиболее вероятное значение критического числа ударов экспоненциально увеличивается при уменьшении статической нагрузки. Численное моделирование потери устойчивости заглубленной в сыпучую среду пластины методом дискретных элементов дают качественно совпадающие с экспериментом результаты.
The article describes the stability testing and calculation results for a heavy column set on the surface of a granular medium, and for a plate buried in the granular medium. The column and plate were exposed to a pre-limiting static load. The granular medium was subjected to multiple weak impacts. The lab-scale tests determined that under such loading, the granular medium evolved gradually to the critical condition and lost the shearing strength. The rate of approaching the critical condition grows with the number of impacts. The critical number of impacts before failure of the medium obeys the log-normal distribution. The most probable value of the critical impact number increases exponentially with the decrease in the static load. The DEM-based modeling of the stability loss in the plate buried in the granular medium yielded the results that qualitatively coincided with the test data.

An oil reservoir is simulated by a model composed of two rectangular glass plates. The space between the plates is filled with glass chips of the similar chemical composition as the plates have. The model allows studying fluid flow in the spaced dipole array representing two wells located symmetrically relative to a certain center. The wells are simulated by holes drilled in the upper plate. The experimentation aimed to assess potential oil recovery enhancement in case of using GBK-F composition. The dependences of fluid flow rate on time in the pumping well, and on the water percentage in the overall fluid volume are obtained. The influence of the intermission in the fluid flow on the oil pattern in the reservoir after treatment with GBK-F composition is analyzed. The efficiency of the reagent is proved.

Установлена связь между синергизмом сочетания анионных и неионогенных реагентов в понижении ими поверхностного натяжения раствора с синергетическим эффектом собирателей во флотации. Показано, что указанные эффекты имеют одну природу. Предложена гипотеза проявления синергизма во флотации, основанная на механизме работы физической формы сорбции собирателя в элементарном акте. Приведены экспериментальные доказательства соответствия мольных концентраций реагентов в понижении поверхностного натяжения раствора смеси и максимального извлечения полезного компонента в концентрат. Рассмотрены причины возможного отсутствия синергетического эффекта во флотации при использовании катионного и анионного собирателей, когда указанный эффект наблюдается в понижении ими поверхностного натяжения раствора. Установлена необходимость учета энергетического взаимодействия собирателя с минералом и окружающей средой. Для анализа изменения смачиваемости минералов реагентами показана возможность применения подхода, основанного на теории Лифшица -Ван-дер Ваальса и кислотно-основного взаимодействия контактирующих объектов. Полученные результаты могут быть использованы при разработке методик подбора сочетаний собирателей и эффективных реагентных режимов флотационного обогащения полезных ископаемых.
It is found that synergism of combination of anionic and nonionic surfactants in reduction of surface tension is connected with their synergetic effect in flotation. These effects have the same nature. The proposed hypothesis of synergism in flotation is based on the mechanism of physisorption of a collector in particle-bubble attachment. The conformity of mole concentrations of surfactants and maximal extraction of useful component to concentrate is experimentally proved. The causes of possible lack of the synergetic effect generated by cationic and anionic collectors in flotation when this effect is observed in reduction of surface tension are discussed. It is found to be necessary to take into account the interaction energy of a collector, mineral and an ambient. The analysis of change in wettability of minerals due to reagents can involve an approach using the Lifshitz theory of Van der Waals force and the acid-base interaction of contact objects. The findings can be used to develop procedures for selecting collectors and efficient reagent modes for mineral flotation.

Abstract
3D concrete printing is an innovative technology poised to transform the construction industry by enabling the automated, layer-by-layer creation of structures directly from digital models. This approach offers numerous advantages over traditional construction methods, including reduced labor costs, faster build times, and the ability to produce complex geometries with high precision. However, unlike conventional mold-cast concrete, 3D printable concrete must support itself without external formwork, posing significant challenges related to material deformation during the printing process. Uncontrolled deformation can lead to structural instability, design deviations, and cumulative errors. Traditional methods for monitoring the geometrical quality of 3D-printed concrete are often insufficient in accuracy and efficiency. Recent advancements in artificial intelligence (AI) present new opportunities for addressing these challenges. AI-assisted methods leverage machine learning to analyze large datasets, enabling more accurate predictions and real-time monitoring and control of deformation during the 3D printing process. In this paper, we explored the application of AI-assisted methods for real-time deformation analysis in 3D concrete printing. Specifically, the Yolo-v5 algorithm, an AI-assisted object detection technique, was employed for the computer vision of extruded concrete filaments. Several quantitative metrics were proposed, including the layer height, layer angle, and curvature. In addition, the rheological properties of 3D-printed concrete were measured to refine the computer vision analysis results. Through experimental validation, we demonstrated the effectiveness of the developed AI-assisted computer vision system in monitoring the 3D concrete printing process.

Published: February 2025

Background: Health seeking behaviour and health seeking pathways are interdependent concepts underpinning accessto healthcare. Understanding these concepts is critical for appropriate and time-dependant stroke interventions.Method: An explorative qualitative study design using one-on-one semi-structured interviews were conducted with16 participants who were either stroke survivors or caregivers of stroke survivors. The Socio-Ecological Model (SEM) wasused to guide data collection and the discussion of the findings in line with the objectives of this study.Findings: The traditional health practitioners (n=11) were the most preferred first encounter followed by public hospital(n = 2) and private hospital (n=1) while others (n=2) self-medicated. On average, it took 30 days for stroke survivors tonavigate the health system. The two themes emerging from this study, were 'health seeking delays', and 'the healthseeking behaviour factor'.Conclusions: A combination of factors influenced the health seeking delays at the levels of the SEM. The participants'health seeking behaviours were influenced by their knowledge, attitude, and beliefs at individual and interpersonallevels as well as dissatisfaction with health services at organizational and public policy levels of the SEM. In the SouthAfrican rural settings, stroke survivors seek medical help from multiple service providers prior to consulting the publichealthcare system due to diverse factors that affect them at interpersonal organizational, community and policy levels.Â Keywords: Health Seeking Behaviour, Health Seeking Pathways, Occupational Therapy Stroke InterventionsÂ
