Authors: Papaev Radii , Larina Yulia , Ezhkov Vladimir , Ezhkova Asiya , Girfanov Aidar
Published: February 2025

Visual inspection of carcasses and internal organs of laying quails of control and experimental groups revealed that morphology of their organs and tissues corresponded to species, age and physiological parameters of birds. Distinctive feature in the micromorphology of the stomach and small intestine of laying quails was noted - activation of gland function, abundance of mucus, insignificant amount of sloughed epitheliocytes on the mucosa of the organs, with a greater degree of manifestation in the stomach in birds receiving dried form, and in the intestine - in quails receiving the native form of black soldier fly larvae. The microstructure of the liver of laying quails of the experimental groups was characterised by a lower degree of fatty degeneration.

Sunflower oil is an indispensable product of functional purpose, which at its reasonable consumption increases immunity, cleanses the body of toxins, improves the brain and heart, and as a result, having a complex effect on the whole body provides an undeniable benefit to human health. Modern development of sunflower oil purification technologies involves improvement of existing and development of new methods and technical means, environmentally safe, accompanied by minimum energy consumption and characterised by increased indicators of technological efficiency, providing the possibility of separation of unnecessary impurities and preservation of valuable components extracted from the oil for their further use. Such a promising method is the purification of sunflower oil in the electric field. The paper considers the possibility of cleaning sunflower oil by an electrostatic precipitator from suspended particles by means of an electric field acting on them. The planned experiment is described and the process of removal of unnecessary impurities is analysed. The justification of the factors and parameters of the experimental study is considered separately. The dependences of the electrical characteristics of oil on the parameters of the purification process are established. Analytical expressions for empirical dependences of energy parameters of the purification process, mode and parameters of ESP operation are determined. The adequacy of theoretical and experimental results has been checked. Having analysed the obtained results, the optimum parameters of effective cleaning and ESP operation were determined, which on the basis of the obtained regression equations should be the following: voltage at ESP electrodes U = 4.4 kV, interelectrode distance b = 0.01 m, oil temperature at the inlet θ = 42°С. The calculated energy consumption at these parameters is equal to 12 W-h/kg.

Published: February 2025

The effect of nanostructured zeolite on embryonic and early postnatal development of Peking ducks cross ‘STAR-53 medium’ was investigated. The surface of hatching eggs was treated with a suspension of nanostructured zeolite with a particle size of 60-120 nm to evaluate its effect on increasing the productivity of ducks. It was found by electron microscopy that particles of nanostructured zeolite penetrate through the porous structure of the shell (pore size 0.2-2 μm) and reach the embryo, stimulating physiological processes. Radiological studies showed no adverse effects on embryo viability, survival and development. After hatching it was revealed that the absolute live weight gain of ducklings in the experimental group was 7.2% (22.6 g) more than in the control group during the first 10 days of life. The obtained results show the prospectivity of using nanostructured zeolite in industrial poultry farming to increase the productivity and quality of growing birds.

Published: February 2025

The work is devoted to the application of vermiculture biotechnology for processing organic waste and obtaining biohumus, as well as assessing the impact of the resulting product on crop yields and quality. The study included laboratory experiments on vermicomposting of different types of organic waste in different proportions with soil filler, as well as field trials using biohumus as a fertiliser for potatoes, carrots and oats. It was found that vermicomposting is effective for processing a wide range of organic wastes to produce biohumus rich in humus, macro- and microelements. The optimum ratio of organic waste and soil filler for biohumus production was 65:35. Field trials have shown that the use of biohumus helps to increase yields and improve the quality indicators of agricultural crops, including an increase in carotene and sugars in carrots, a decrease in non-protein nitrogen in potatoes, and a reduction in disease and pest damage. The results confirm the prospects of vermiculture as an environmentally safe method of waste utilisation and obtaining a valuable organic fertiliser.

Authors: Yudaev Igor Viktorovich , Sharov Ivan Vasilievich
Published: February 2025

The use of various mobile electro-technological installations and aggregates to perform various field operations (weeding, potato haulm desiccation, soil pest control, pre-harvest preparation of sunflower and tobacco, etc.), carried out directly in crops and plantings of cultivated crops or on agricultural land, is now considered as a quite effective alternative to chemical components, characterised by environmental friendliness and high efficiency. In the considered variant of technical realisation it is proposed to apply high voltage electrical pulses to disturb normal plant life. The purpose of the research presented in the article is to analyse possible variants of implementation of treatment of weeds and undesirable grasses with the purpose of their destruction, and to estimate the parameters of the output unit of the electrotechnological installation. Both, substantiated from the point of view of technological efficiency, variants of electric energy supply to weeds are realisable in practice and the choice of each of them is based on the configuration of the surface and the cultivated soil area, the degree of their infestation with specific types of undesirable grasses and the capacity of the electrotechnological mounted or trailed unit. At the same time, the voltage on the electrode system should be greater than the sum of the voltage drop on all elements of the treatment current flow circuit, and the choice of the capacitance value directly depends on the energy used for treatment of undesirable grasses, the treatment voltage and the operation mode of the capacitor bank. The proposed approach in estimating the parameters of the discharge circuit and electrode system relies on experimental prospecting studies with those species of weeds that directly grow in the places of application of the electric pulse unit. The presented sequence of determining the main parameters of the output unit of the unit - discharge circuit, should provide sufficient accuracy for practical adjustment and adjustment of the unit.

A comprehensive approach to the creation of a universal industrial line for the production of food and feed ingredients from various agricultural raw materials based on the integration of biotechnological, baromembrane and ultrasonic methods is presented. The research included the development of methods of directed enzymatic catalysis intensified by ultrasonic influence, as well as modern technologies of membrane concentration and purification. It was experimentally established that the use of an integrated approach allows to significantly increase the yield of target components from plant and secondary raw materials, such as proteins, amino acids, vitamins, pectin substances. In particular, at processing of grain bard the protein content in dry matter increased up to 40-45%, and at processing of beet pulp the yield of pectin substances increased by 20-25%. Ultrasonic treatment reduced extraction time by 10-15% and enzyme consumption by 5-10%. The results obtained demonstrate the prospects of this approach for the creation of environmentally friendly and resource-saving production of food and feed ingredients.

Authors: Lu Shunyao , Yang Dongfang , Huang Xiaoqing , Chen Tao
Published: February 2025

In glass curtain wall buildings, the solar radiation irradiation depth is greater, more solar radiation heat gain also has a greater impact on the indoor thermal environment. In the traditional air-conditioning system design, the inner and outer zoning of air-conditioning often relies on engineering experience and is not applicable to glass curtain wall buildings, therefore, it is necessary to propose a new method of internal and external zoning for glass curtain wall buildings. In this paper, the distribution of solar radiation in the room throughout the year is analysed to clarify the depth of solar radiation in the room and the influence range on the indoor radiant thermal environment. The results show that the influence range of solar radiation in the south-oriented room is 2m in summer and 3m in winter, and the influence range of solar radiation in the east and west oriented room is 3m in summer and about 2.5m in winter. The results of this paper provide a theoretical basis for the delineation of the inner and outer zones of buildings with glass curtain walls, which can reduce the thermal discomfort of the people in the room and the energy consumption.

Analysis on seismic performance of a new type of stiffening rib angle steel damper
Authors: Hao Jinfeng , Diao Fawei , Qu Mingyang
Published: February 2025

This paper proposes a stiffening angle steel damper for beam-column joints. The ABAQUS software is used to study the influence of the thickness, opening ratio and number of openings of the stiffening rib on the energy dissipation performance of the damper. A total of 7 models are set up. Through the reciprocating displacement loading method, the energy dissipation capacity is evaluated by analyzing the damper's hysteretic curves, stress distribution, skeleton curves, and key mechanical parameters under different conditions. The study shows that: Under normal circumstances, it is not advisable to use too thick stiffening ribs, but in areas prone to strong earthquakes, the thickness of the stiffening ribs can be appropriately increased or the opening ratio of the stiffening ribs can be reduced to enhance its energy consumption capacity; at the identical open-hole ratio of the stiffening ribs, as the number of openings increases, the distribution of its energy consumption is more uniform.

Published: February 2025

There are many types of cement in Guangdong, each with its own differences, so it is important to study the adaptability of polycarboxylate superplasticizer to cement in Guangdong. The chemical composition and physical properties of the cement were tested, and the influence of cement performance on concrete was explored. The results show that the specific surface area of cement affects the dosage of superplasticizer. The larger the specific surface area, the greater the cement adsorbs the superplasticizer. The smaller the specific surface area difference, the better the superplasticizer adaptability. Meanwhile, the chemical composition of cement will affect the strength of concrete, and the more active components there are, the higher the strength.
The Impact of Calcined Electrolytic Manganese Residue on the Sulfate Resistance of Cement-Based Materials
Authors: Jia Zhenyu
Published: February 2025

To investigate the sulfate resistance of cementitious materials incorporating electrolytic manganese residue (EMR), EMR samples (10%, 15%, 20%) were prepared by activating EMR at 800°C. The mass and compressive strength of specimens at various carbonation ages were measured, and the pore size distribution at different soaking ages was analyzed using nuclear magnetic resonance (NMR). Results indicate that the incorporation of calcined EMR enhances the sulfate attack resistance of cement mortar, with optimal performance observed at a 15% EMR content. During the initial immersion phase, both the mass and compressive strength of 15% EMR cement mortar and the control group showed positive increases. After 180 days of immersion, the mass of 15% EMR cement mortar continued to increase, and its compressive strength exceeded that of the control group by 18.53 MPa. Additionally, the pore signal of 15% EMR cement mortar was lower compared to all other specimens, indicating denser pores less susceptible to sulfate erosion. Overall, these findings provide theoretical support for the utilization of electrolytic manganese residue in cement- based materials.

Published: February 2025

As a widely used building cement material, the performance of cement directly affects the quality and durability of the building. In the process of concrete production, admixture is an additive with a key role, which can effectively improve the working performance of concrete and enhance the mechanical characteristics of concrete itself. With the continuous progress of technology, various types of water-reducing agents emerge at the historic moment, and the effect of improving the strength and durability of concrete is different. This paper mainly analyzes different types of water reducer, retarder, pilot, mixing factors on the concrete performance, and concluded that the best mixing scheme is: polycarboxylic acid water reducer: retarder (sodium gluconate): pilot: water =150:25:0:3:824.7, concrete performance all meet the construction requirements. It provides theoretical basis and guidance for commercial mixed enterprises to choose water- reducing agent products and service positioning.

Authors: Zhong Zhixian , Fang Guangxiu , Wu Suobo , Piao Xingchen
Published: February 2025

To study the effect of double mixing of waste rubber and fly ash on the strength and water permeability of pervious concrete, this paper adopts an orthogonal experimental design, aiming at exploring an optimal range between the mixing amount of waste rubber and fly ash by analyzing the effect of different mixing amounts of the two on the compressive strength and water permeability coefficient of the pervious concrete and analyzing the design of the mixing ratio with an optimized balance of strength and water permeability coefficient. The results show that an appropriate amount of fly ash can improve the compactness and compressive strength of concrete, but too much will reduce the compressive strength. Waste rubber can increase the compressive strength within a certain mixing range, but too much will reduce it. The water permeability coefficient decreases with the increase in the dosage of waste rubber and fly ash. It was found that the best overall performance of pervious concrete was achieved when the water-cement ratio was 0.28, at 15% fly ash and 10% waste rubber. This study provides a new type of road material for the practical application of previous concrete, which helps to solve the problem of waste tire pollution and promotes the development of green building materials.

Authors: Liu Zilong , Ai Jianke , Jia Shuming , Zhong Jimin
Published: February 2025

Pipeline transportation is of great significance in modern society but faces many potential safety hazards, with vibration being a significant external cause of pipeline leakage accidents. This article reviews the impact of different strain rate vibration sources (blasting vibration and mechanical vibration) on buried pipelines and the current research status of the dynamic responses of PE pipes and steel pipes. Blasting vibration has a short duration and high strain rate, which can directly damage the pipeline or indirectly cause its settlement and deformation; mechanical vibration has a wide range of sources, and the impact of impact loads and excavation loads on pipelines is complex. PE pipes have good flexibility but limitations in temperature and compressive strength, while steel pipes have a large market demand but are complexly affected by dynamic loads. Finally, the current research deficiencies are pointed out, and future research directions are proposed, including in-depth exploration of failure mechanisms, improvement of safety standards, optimization of pipe material research, strengthening of monitoring and early warning, and multidisciplinary cross-research, with the aim of enhancing the safe operation level of buried pipelines.
The influence of embankment top load and water level change on the stability of soil embankment slope
Authors: Jiang Minmin , Xiao Xulian
Published: February 2025

Earthen embankments and earth and rock dams along rivers are often used to double as highways, which makes the embankments subject to the effects of seepage of water as well as top loading of the embankment. In order to investigate the effects of steady state water level seepage and top load on the slope stability of an earth embankment, a homogeneous earth embankment was modeled using finite element software, and slope stability analyses were carried out under different operating conditions. The results show that both steady-state seepage and top-of-embank loading have a negative effect on the stability of the earthen embankment, and the negative effect will be greater under coupling.
Numerical Simulation of Visualized Grout Diffusion in Backfill-grouting of Shield Tunnel

Published: February 2025

Synchronous grouting in shield tunnel construction plays a critical role in enhancing tunnel impermeability, ensuring precise alignment of segment rings, and mitigating surface settlement. Despite its importance, limited research has been conducted on the visualization of numerical simulations for grouting behind the shield tunnel wall. This study addresses this gap by simulating the grouting diffusion process during shield tunnel post-grouting using CFDEM software. The simulation results reveal that grout injected from the upper opening of the tunnel initially diffuses in a hemispherical pattern centered at the injection point and subsequently migrates downward along the outer diameter of the segment under the influence of gravity. Conversely, grout from the lower outlet rapidly fills the annular gap and transitions to a permeation diffusion phase. At a grouting volume of 100%, the slurry coverage area reaches 62.5%, with a slurry waste of 37.4%. When the grouting volume increases to 200%, the coverage area marginally improves to 73.1%. Balancing grouting effectiveness with construction costs, the optimal grouting effect is achieved at a grouting volume of 100%, as excessive grouting will not be greatly improved and leads to substantial material waste. To achieve complete grout coverage, particularly in unfilled regions at the tunnel head and sides, secondary grouting is recommended instead of further increasing the initial grouting volume. This approach minimizes material waste while maintaining construction efficiency.
Research on Valve Optimization and Control Technology for Water Hammer Protection in Long-Distance Pressurized Water Conveyance Systems
Authors: Hu Yiming , Dong Shen , Lv Mou , Li Hang
Published: February 2025

In long-distance water transfer projects, changes in operating conditions or accidental power failures can cause changes in the flow regime inside the pipeline, triggering water hammer phenomena. This results in instantaneous pressure overload in the system, which can damage the water conveyance pipelines and associated structures, impacting the safety of water transmission. To effectively reduce the maximum water hammer pressure generated during pump station shutdown operations, this study first uses HAMMER software for hydraulic modeling of the water transfer system. Hydraulic simulations are conducted for various operational conditions, including normal system operation and sudden pump shutdown scenarios, to calculate the maximum water hammer pressure and other parameters, and analyze feasible and effective water hammer control measures. Next, by analyzing and processing 200 sets of water hammer pressure data under different valve conditions, this study investigates the pressure variation patterns in the system under different operating conditions. A data-driven neural network-based water hammer pressure simulation model is developed to quantitatively analyze the impact of operational parameters such as valve quick-closing time and quick- closing angle on the system's maximum water hammer pressure. With the goal of controlling the maximum water hammer pressure, a water hammer regulation model based on valve closure strategy optimization is established. This model is solved using intelligent optimization algorithms to propose the optimal valve control scheme under pump shutdown conditions. Case studies show that the data-driven neural network- based water hammer pressure simulation model accurately simulates the impact of different valve conditions on water hammer pressure. Furthermore, the Bat Algorithm (BA) effectively optimizes the valve control strategy, significantly reducing the maximum water hammer pressure during pump shutdown operations. This approach effectively controls the destructive impact of water hammer on the water transfer system and greatly enhances the safety of long-distance pressurized water transfer.

Black soldier fly larvae, as a biological converter of organic waste, can efficiently and safely degrade kitchen waste, convert it into their own nutrients, and realize the resource utilization of kitchen waste. Since the content of crude oil in black soldier fly larvae accounts for more than 35% of the dry weight of insects, the oil of larvae in the fifth instar and prepupal stage is used as the test raw material, with reference to the national standard GB5009.168-2016 fatty acids were extracted and methylated with methanol solution, Gas chromatography-mass spectrometry was used. The results showed that the main chemical components of the esterification products of the fifth instar insect oil were oleic acid, palmitic acid and lauric acid, and the three fatty acids accounted for 66.27%, 17.23% and 11.39% of the total respectively. The main chemical components were methyl laurate, methyl oleate, methyl linoleate and methyl palmitate. The four fatty acids accounted for 46.62%, 17.88%, 17.42% and 13.23% respectively.

Published: February 2025

Environmental self-identity (ESI) is a key factor in promoting sustainable behaviours. Hence, it is crucial to find the antecedents that can shape environmental self-identity. The present study conducted a questionnaire survey (N = 478) to verify the roles of past sustainable behaviours and biospheric values in developing environmental self-identity among Chinese women. The results revealed that both past sustainable behaviours and biospheric values had a significant and positive correlation with ESI. Furthermore, biospheric values partially mediated the relationship between past sustainable behaviours and ESI. These findings provide a theoretical framework for policy making and implementation, and practical foundation for empowering the leading role of women in households and in developing green families.

Chickpea (Cicer arietinum L.) is the second most important legume in the world, grown on an area of approximately 12.6 million ha in 55 countries. Over the past decade (2004-2006 to 2014-2016), the area under chickpea production worldwide has increased by 23% and the yield by 17%. Chickpea varieties yield 0.6-0.8 t/ha on rainfed lands of Uzbekistan and 2.2-3.2 t/ha on irrigated lands. Depending on the planting method and the biology and morphology of the variety, 60-80 kg of seed is used per ha. In Uzbekistan, it is mostly cultivated on fertile lands. On irrigated lands, inter-row cultivation is carried out 1-2 times. The main goal of this research is to select new productive genotypes with high photosynthetic productivity and suitable for harvesting by mechanisms. According to the results of measurements carried out in the budding, flowering and podding phases, the NDVI value varied from 0.235-0.683. When studying the relationship between NDVI and yield, it was found that there was a positive correlation of r=0.1 in the budding phase, r=0.31 in the flowering phase, and r=0.44 in the podding phase. The amount of chlorophyll in the budding, flowering, and podding phases varied from 22.6 to 49.6. When studying the relationship between the amount of chlorophyll in the leaf and yield, it was found that there was a positive correlation of r=0.33 in the budding phase, r=0.28 in the flowering phase, and r=0.22 in the podding phase. It is clear from this that increasing the green biomass of a plant contributes to increasing productivity. A decrease in the amount of chlorophyll in the leaves during the final stages of development reduces photosynthetic productivity and leads to a decrease in productivity. The KR20-CICTN-17 (Bardosh) variety, which ripens early, is productive, is adapted to mechanization, has high photosynthetic productivity, and has indicators higher than the standard varieties, was selected in the competitive variety testing nursery and was recommended for submission to the Center for Testing Agricultural Crop Varieties.
Performance analysis of DMF-free perovskite solar cells with vacuum quenching
Authors: Mochizuki Toshimitsu , Araki Shota , Takato Hidetaka , Tanahashi Katsuto
Published: February 2025

In pursuit of perovskite solar cells compatible with silicon tandem cells, we have been exploring the vacuum quenching method. Given that N,N-dimethylformamide (DMF) is a known carcinogen in animals, we used a mixed solvent of 1-Methyl-2-pyrrolidone and Dimethyl Sulfoxide as safer alternatives. We optimized the vacuum quenching method by adjusting parameters such as annealing temperature and additives to the ink to achieve higher efficiency. We present the characteristics and structural features of solar cells in which perovskite layers were crystallized using this optimized vacuum quenching method. We fabricated a DMF-free vacuum quenched p-i-n CsFAMAPb(I/Br)3 perovskite solar cell with an energy gap (Eg) of 1.69 eV and an effective area of 1.04 cm2. We then evaluated its current-voltage characteristics using the 4-terminals method. A peak power conversion efficiency of 17.0% in the forward scan and 13.2% in the reverse scan was achieved without passivation, and 18.0% in the forward scan and 17.1% in the reverse scan by incorporating 0.5% 2-Phenylethylamine Hydroiodide (PEAI) into the perovskite ink. We measured photoluminescence spectra of perovskite crystal thin films, prepared under the same conditions as the solar cells. The photoluminescence spectra showed a consistent pattern across all samples with two gaussian components. As the conditions were optimized, the component on the high-energy side approached the intended bandgap. Furthermore, upon the addition of PEAI, the band-edge was accentuated. The XRD results indicate that the major peaks can be attributed to the cubic perovskite structure. The addition of PEAI does not significantly change the peak positions or intensities, but it reduces a minor peak attributed to PbI2, suggesting suppressed PbI2 precipitation. Our results indicate that the optimized conditions for vacuum quenching can produce perovskite crystals without undesirable precipitates, leading to an increase in the efficiency of solar cells.
High precision, high time-cadence measurements of the Mg II index of solar activity by the GOES-R Extreme Ultraviolet Irradiance Sensor 1: EUVS-C design and preflight calibration
Authors: E McClintock William , Snow Martin , Crotser David , Eparvier Francis
Published: February 2025

EUVS-C is one component of the Extreme Ultraviolet Irradiance Sensor (EUVS) instrument. EUVS together with the X-ray sensor (XRS) comprise the Extreme Ultraviolet and X-ray Irradiances Sensors (EXIS) investigation aboard the GOES-R satellite series which includes GOES-16, -17, -18, and -19. From their vantage points in geostationary orbit, the EUVS-C instruments make high-precision (better than 1 part in 104), high-time-cadence (3 seconds) measurements of the solar Mg II Index with moderate (0.1 nm) spectral resolution. The Index, also referred to as the Mg II core-to-wing-ratio, is a proxy for chromosphere activity that correlates with solar extreme ultraviolet (EUV) irradiance. Mg II produces two bright chromosphere emission lines in the Sun’s spectrum at 279.55 nm and 280.71 nm (Mg II k and h) that appear in the cores of their respective photospheric absorption lines. Measuring the ratio of emission from the core (chromospheric) to that from the wings (photospheric) provides an index that is relatively insensitive to changes in radiometric performance that often occur when scientific instruments observe the Sun. EUVS-C design specifications were informed by earlier research reporting index variability of approximately 0.2% on time scales of 6 – 10 minutes, increasing to approximately 0.3% and approximately 0.55% for 30 and 80 minutes, respectively. This paper describes the EUVS-C instrument design and implementation, its ground calibration and characterization, and anticipated measurement performance. A companion paper describes initial EUVS-C flight measurement performance.

EUVS together with the X-ray sensor (XRS) comprise the Extreme Ultraviolet and X-ray Irradiances Sensors (EXIS) investigation (Machol et al. 2020) aboard the GOES-R satellite series which includes GOES-16, -17, -18, and -19. From their vantage points in geostationary orbit, the EUVS-C instruments measure the solar Mg II Index, also referred to as the Mg II core-to-wing-ratio, which is a proxy for chromosphere activity and correlates with solar extreme ultraviolet (EUV) emission. Mg II produces two bright chromosphere emission lines appearing in the sun’s spectrum at 279.55 nm and 280.71 nm (Mg II k and h) that appear in the cores of their respective photospheric absorption lines. Measuring the ratio of emission from the core (chromsopheric) to that from the wings (photospheric) provides an index that is relatively insensitive to changes in instrument performance. In 2005, Snow & McClintock used 0.1nm resolution data to show that the intrinsic solar variability in the index (as opposed to instrument noise) is on the order of 0.2% on time scales 5-10 minutes. EUVS-C is designed to exceed these performance requirements. A companion paper describes the instrument design and its pre-flight calibration. This paper describes the operational implementation for the algorithm that produces the Index, flight calibrations, and the initial instrument flight performance. Each EUVS-C currently operating (GOES-16, -17, and -18) is providing high time-cadence (3 seconds), high precision (1 part in 104) Index determinations.  Spectral shifts arising from spacecraft orbital motion introduce a systematic 0.1% diurnal variation in absolute index values.  Additionally, wavelength dependent radiometric responsivity degradation leads to a systematic increase in the reported index on a timescale of years at an average rate of 0.2% per year. These systematic effects can be mitigated with additional post data processing.

Background Primary care pediatricians play an important role in genetic testing, including referrals, test ordering, responding to results, assessing risk, treatment, and managing care. As genetic testing rapidly evolves to include new tests identifying patients at risk for certain conditions, alert-based clinical decision support is insufficient in assisting pediatric primary care providers in working with patients, parents, genetics, and other specialties. Supporting pediatricians in the return of these results requires addressing gaps in genetics training and integrating genetics into practice with education, information resources, and specialized tools.

Objectives This study aimed to capture requirements for developing systems and processes to support primary care pediatricians in the return of genome-informed risk assessments.

Methods We performed a requirements analysis to inform the design of clinical decision support tools and processes for pediatric providers of patients who received a genome informed risk assessment, a novel test that combines polygenic risk scores with patient and family histories to deliver a risk assessment for common medical conditions. We developed an interview guide consisting of scenario presentations, questionnaires, and semi-structured questions to elicit provider responses on a broad set of requirements to manage results with patients and caregivers.

Results Twenty providers from 10 primary care pediatric practices within a single health system participated in the study. The findings demonstrated that providers feel responsible to be involved in the process of returning results but require a support system that integrates education, provider and patient information resources, effective communication with genetics, and electronic health record decision support tools that can accommodate a range of clinical scenarios and provider workflow preferences.

Conclusion Supporting providers with the return of genetic testing results such as the genome informed risk assessment requires a comprehensive approach to decision support consisting of education, communication, and a comprehensive and integrated set of electronic health record tools.

Hintergrund Die kongenitale Tränenwegstenose, eine häufige Erkrankung bei Neugeborenen, ist durch eine Verengung des Tränenwegsystems, häufig am Ductus nasolacrimalis, gekennzeichnet. In den meisten Fällen öffnet sich der Tränenweg spontan im 1. Lebensjahr, unterstützt durch Massagen. Bei fehlender Besserung kann eine operative Sondierung erforderlich sein. Ziel dieser Studie war die Analyse der Erscheinungsbilder und Ergebnisse operativ behandelter Tränenwegstenosen bei Kindern in unserer Klinik.

Patienten und Methoden In einer retrospektiven Analyse wurden elektronische Krankenakten von Patienten unter 18 Jahren ausgewertet, die zwischen 2011 und 2023 wegen einer kongenitalen Tränenwegstenose behandelt wurden. Erfasst wurden demografische Daten, Symptome, Lokalisation der Stenose, operative Therapie und Ergebnisse. Zudem wurden Eltern der Patienten zur postoperativen Situation und Symptomatik befragt. Die Studie wurde von der Kantonalen Ethikkommission Zürich (BASEC2022-00830) genehmigt.

Resultate Von insgesamt 147 identifizierten Patienten (39 weiblich, 62 männlich) konnte bei 69% eine Analyse mit vorliegendem Einverständnis erfolgen. Das Alter bei Erstuntersuchung lag zwischen 8 Monaten und 12 Jahren (median 27 Monate). Eine unilaterale Stenose wurde bei 69% und eine bilaterale bei 31% festgestellt. Die häufigsten Symptome waren Epiphora (95%), verklebte Zilien (68%), muköses Sekret (23%) und Rötung der Lider/Konjunktiva (19%). Bei 11% wurde intraoperativ eine Malformation festgestellt. Eine 2. Sondierung war bei 10% notwendig, wobei das Alter zwischen 18 und 69 Monaten lag (Median 38 Monate). Eine Dakryozystorhinostomie wurde bei 4% durchgeführt (Alter 92 – 145 Monate, median 113 Monate). Nach der Operation berichteten 70,5% subjektiv und/oder objektiv über Beschwerdefreiheit, 22,7% über anhaltende Epiphora und 6,8% über verkrustete Zilien. Bei 77/101 lag eine Beantwortung des Fragebogens vor. Hierbei berichteten 92%, dass das tränende Auge nicht
mehr vorhanden war und 96% benötigten keine Therapie mehr. 97% gaben an, dass die Operation ohne Komplikationen verlief, 17% erlebten erneut tränende Augen, und 6% benötigten zusätzliche, nicht tränenwegbezogene Behandlungen.

Fazit In den meisten Fällen ist eine alleinige Sondierung und Spülung zur Heilung ausreichend. Eine temporäre Sondeneinlage ist häufiger bei älteren Kindern notwendig. Eine Intervention nach dem 18. Lebensmonat beeinflusst die Heilung nicht negativ.
