Published: July 2023

Reactive powder concrete (RPC) is one of the most recent and significant advancements in the world of building. Due to its higher concrete characteristics, it has a common excessive benevolence happening in the globe at the moment, excessive ductility, shrinkage resistance, and corrosion and abrasion resistance. Investigated is the method for amending the RPC experimentally in punching shear slab action and the properties of construction material to investigate properties of volumetric ratios of steel fiber, and silicas fume, tensile steel ratio, the most important component for construction is reinforced concrete, which works well with other materials to create structures in any shape that is needed. In the present research, investigational work of RC slab with (1,000 × 1,000 × 60) mm dimensions was tested. This study aims to see how the relative volume of steel fibers (Vf) and silica fume content (Sf) affect the actions of RC slabs after being exposed to fire. It originated that a concrete mix containing 2% steel fibers improved the RPC slab's cracking and final punching shear. The existence of reactive powder increases fire resistance. This study's experiment aimed to see how reactive powder and Slab's ultimate punching shear strength were affected by replacement ratio. Whenever a fire is present. After fire exposure, the initial and subsequent stiffness of reinforced concrete slabs reduced considerably the temperature grew from 25 to 750°C.
Numerical and experimental analysis of the heat transfer process in a railway disc brake tested on a dynamometer stand
Authors: Wolff Andrzej , Kukulski Jacek
Published: July 2023

The effectiveness of railway brakes is highly dependent on the thermal condition of the brake disc and friction linings. An effective research method for the heat transfer process in brakes was computer simulation and experimental tests on a full-size dynamometric test bench. A two-dimensional, axially symmetric numerical model of transient thermal conductivity in a railway brake was presented. Appropriate boundary conditions of the problem were applied, describing the heat generated in the brake and discharged to the environment. The problem was solved using the finite-element method. This article presents exemplary results of the brake temperature calculations obtained using the numerical model and the results of experimental tests carried out on two types of brake discs.
Teaching Tale Types to a Computer: A First Experiment with the Annotated Folktales Collection
Authors: Eklund Johan , Hagedorn Josh , Darányi Sándor
Published: July 2023

Computational motif detection in folk narratives is an unresolved problem, partly because motifs are formally fluid, and because test collections to teach machine learning algorithms are not generally available or big enough to yield robust predictions for expert confirmation. As a result, standard tale typology based on texts as motif strings renders its computational reproduction an automatic classification exercise. In this brief communication, to report work in progress we use the Support Vector Machine algorithm on the ten best populated classes of the Annotated Folktales test collection, to predict text membership in their internationally accepted categories. The classification result was evaluated using recall, precision, and F1 scores. The F1 score was in the range 0.8–1.0 for all the selected tale types except for type 275 (The Race between Two Animals), which, although its recall rate was 1.0, suffered from a low precision.

Case report: mitochondrial diabetes mellitus in a Chinese family due to m.3243A>G
Authors: Bai Wei , Zhang Qian , Fan Yanbin , Han Tianyan , Gu Nan , Zhang Yao , Liang Furong , Ma Yinan , Xiong Hui
Published: July 2023

Objectives

Mitochondrial diabetes mellitus is caused by dysfunctional mitochondria and is often misdiagnosed because of its various clinical manifestations. It’s even rarer in children, and without a clear family history of diabetes with hearing loss, it’s often difficult to diagnose.

Case presentation

This is a case study of a family with maternally inherited diabetes mellitus and deafness (MIDD). The proband was an adolescent girl with diabetes with a family history of type 2 diabetes (T2DM) for three generations. Family members have undetected hearing impaired. The proband could not be diagnosed with type 1 diabetes (T1DM) or T2DM. Therefore, whole exome and mitochondrial gene sequencing was performed, which identified an m.3243A>G mutation in the mitochondrial DNA.

Conclusions

This suggests that we should be alert to the possibility of hereditary diabetes, especially mitochondrial diabetes in patients with atypical diabetes. A thorough physical examination is very important. What is new: (1) Mitochondrial diabetes in childhood may not be accompanied by deafness even with highly heteroplasmy levels. (2) In MIDD patients, sometimes hearing loss cannot be perceived, which requires us to conduct detailed physical examinations and related examinations. (3) The use of metformin in MIDD patients did not have adverse consequences.
Briggs v. Southwestern Energy Production: Hydraulic Fracturing and Subsurface Trespass
Authors: Merrill Thomas W. , Smith Henry E.
Published: July 2023

The tort of trespass to land has proven to be controversial as applied to airplane overflights (and more recently to drones) as well as to oil and gas production using hydraulic fracking technology. The key to applying trespass to intrusions above and below the surface of land is to distinguish between possession of land and the right to possess land. Surface owners have the right to possess the column of space above and below the surface (a kind of option value), but only to the extent that this space is subject to possible effective possession. The Pennsylvania Supreme Court in Briggs v. Southwestern Energy Production concluded that fracking can result in physical intrusions that can be detected using available monitoring technology. The court further concluded that such physical intrusions should be subject to trespass liability. We argue that these conclusions are correct insofar as such intrusions interfere with a surface owner’s possible effective possession – the action of the intruder necessarily means that the surface owner could also find it economically advantageous to engage in production activity in this portion of subsurface space itself. The decision confirms the utility of the law of trespass to the architecture of property, in that it establishes an indispensable baseline against which exchanges of rights and regulatory modifications of rights can occur.

Parasitic gap patterns and hierarchy preservation in German
Authors: Gould Isaac
Published: July 2023

This paper discusses how German parasitic gap data from various earlier publications illustrate two patterns of systematic grammatical variation in the language, which have not been previously identified as such in the literature. I show how Heck and Himmelreich’s (Heck, Fabian & Anke Himmelreich. 2017. Opaque intervention.Linguistic Inquiry48. 47–97) analysis for one pattern, although not able to currently capture both patterns, can be extended by allowing for variation in the positions targeted by scrambling along with the phrase markers that constitute domains for linearization. The resulting unifying analysis highlights how different grammatical mechanisms can in various ways (both local and global) have the effect of preserving the hierarchical relations involved in multiple movement dependencies.
Lexical coherence in contemporary Italian: a lectometric analysis
Authors: De Pascale Stefano , Marzo Stefania
Published: July 2023

This paper explores the theoretical question of linguistic coherence by investigating lexical variation in contemporary Italian. In order to tackle issues regarding the coherence of lexical choice, variation is investigated with methods from lexical lectometry, which approaches the structure of language varieties (i.e. lects) by studying aggregate-level lexical distances between them. Based on uniformity measures, as introduced by Geeraerts et al. (1999), we have calculated the internal and external uniformity of spoken and written traditional standard Italian (represented by the academic section of the CORIS corpus for written Italian and the formal parts of the KIP corpus for spoken Italian) and neo-standard Italian (represented by the ParlaTO corpus for spoken Italian and the newspaper section of the CORIS corpus). The results confirm the hypothesis that two standard norms coexist in contemporary Italian and that traditional standard Italian appears to be more coherent at the lexical level than neo-standard Italian. Yet the study also indicates that other forms of coherence exist in contemporary Italian, depending on the adopted theoretical and methodological framework.
Autism Spectrum Disorder
Authors: Gillespie Heather
Published: July 2023

Adults have a significantly harder time being diagnosed with autism, and this is due to many reasons, such as the paucity of information about adults with autism, their diagnosis being missed as a child, lack of providers who feel confident in their knowledge to diagnose autism in adults, and an autistic adult’s ability to mask and cope in a neurotypical world since childhood, among others. Few tests are available and specifically target adult diagnosis. Most tests are created for children or youth and may not account for the difference in the presentation of autism in adults and the coping skills and masking they have required to develop throughout their lives. This paper talks about the need for adequate knowledge and testing for autism in the adult population.

Published: July 2023

Endocrine therapies targeting estrogen signaling, such as tamoxifen, have significantly improved management of estrogen receptor alpha (ERα)‐positive breast cancers. However, their efficacy is limited by intrinsic and acquired resistance to treatment, and there is currently no predictive marker of response to these anti‐estrogens to guide treatment decision. Here, using two independent cohorts of breast cancer patients, we identified nuclear PRMT5 expression as an independent predictive marker of sensitivity to tamoxifen. Mechanistically, we discovered that tamoxifen stimulates ERα methylation by PRMT5, a key event for its binding to corepressors such as SMRT and HDAC1, participating in the inhibition of the transcriptional activity of ERα. Although PRMT5 is mainly localized in the cytoplasm of tumor cells, our analyses show that tamoxifen triggers its nuclear translocation in tamoxifen‐sensitive tumors but not in resistant ones. Hence, we unveil a biomarker of sensitivity to tamoxifen in ERα‐positive breast tumors that could be used to enhance the response of breast cancer patients to endocrine therapy, by fostering its nuclear expression.
Culturomics as a tool to better understand the human milk microbiota and host–microbiota interactions
Authors: Cheema Simran Kaur , Li Ranran , Cameron Simon J S
Published: July 2023

For almost a century, it has been accepted that human milk contains viable microbial cells. However, for a considerable amount of this period, it was believed that they were the result of exogenous contamination, primarily from the skin or non-sterile handling. Early work using culture-dependent methods, supported by molecular profiling, however, identified the presence of lactic acid bacteria from an endogenous origin. This provided evidence that the human milk microbiota consisted of microorganisms that were not found solely on the skin surface and therefore could not result from contamination. Through the advent of next-generation sequencing, the field of microbiota research has caused a paradigm shift away from a typical focus on the presence of pathogenic microorganisms in human milk. This had led to a broad appreciation that the human milk microbiota consists of several hundred species of non-pathogenic commensal microbes – with many anaerobic microbial taxons being found only in the gastrointestinal tract outside of human milk. Nevertheless, as our appreciation of the complexity and diversity of the human milk microbiota has improved, many questions relating to the functional basis of host–microbiota interactions in the newborn infant’s gastrointestinal tract remain outstanding. To address these, mechanistic studies will be required in which the utilisation of isolated microorganisms will be essential. As such, a return to culture-dependent methods in the new paradigm of culturomics will be required. In this review, we bring together the current understanding of the human milk microbiota and how culturomics could play a fundamental role in furthering our understanding.

Characterization of structural changes in lignin during continuous batch kraft cooking of Eucalyptus globulus
Authors: Rutkowska Ewa W. , Wollboldt Petra , Zuckerstätter Gerhard , Weber Hedda K. , Sixta Herbert
Published: July 2023

Eucalyptus globulus wood originating from plantations in Uruguay was subjected to continuous batch kraft cooking (CBC), applying mill-like conditions. Pulp samples were taken at different stages of CBC cooking being representative for all three cooking phases. The residual lignin was successfully isolated in a reasonable yield by a new method, the dissolved wood lignin (DWL) protocol, which is based on the total dissolution of ball milled wood and pulp samples in dimethylsulfoxide and N-methylimidazole (DMSO/NMI) followed by precipitation in dioxane/ water to separate lignin and carbohydrate fractions. For comparative reasons, the lignin was also isolated by a conventional mild acidolysis (AL) method. Extensive structural lignin characterization using 1D and 2D NMR revealed that the DWL protocol allows the isolation of less altered lignin than the AL method. During bulk and residual delignification, the S/G ratio of lignin remaining in the fibers continuously decreased, while the content of b-O-4 units and phenolic OH groups remained almost unaffected, suggesting that the CBC process permits enhanced delignification efficiency and good bleachability.
Variation of cell features and chemical composition in spruce consisting of opposite, normal, and compression wood
Authors: Tarmiana Asghar , Azadfallah Mohammad
Published: July 2023

A number of important anatomical features and chemical composition in opposite, normal, and compression wood of Norway spruce (Picea abies) were evaluated to optimally utilize spruce logs containing compression wood. A comparison of axial tracheid and ray cell features in the opposite, normal, and compression wood was provided. Lignin, cellulose, acetone-soluble, and water-soluble extractive contents of the woods were also determined. Results revealed a major variation in the anatomical and chemical characteristics of the woods. Compression wood showed extremely different microscopic features, and chemical composition compared to normal and opposite wood. In most of features investigated in the present study, normal wood occupied a transitional position between opposite and compression wood.
A review of U.S. and Canadian biomass supply studies
Authors: Gronowska Magdalena , Joshi Satish , MacLean Heather L.
Published: July 2023

An improved understanding of lignocellulosic biomass availability is needed to support proposed expansion in biofuel production. Fifteen studies that estimate availability of lignocellulosic biomass quantities in in the U.S. and/or Canada are reviewed. Sources of differences in study methods and assumptions and resulting biomass quantities are elucidated. We differentiate between inventory studies, in which quantities of biomass potentially available are estimated without rigorous consideration of the costs of supply, versus economic studies, which take into consideration various opportunity costs and competition. The U.S. economic studies, which included reasonably comprehensive sets of biomass categories, estimate annual biomass availability to range from 6 million to 577 million dry metric tonnes (dry t), depending on offered price, while estimates from inventory studies range from 190 million to 3849 million dry t. The Canadian inventory studies, which included reasonably comprehensive sets of biomass categories, estimate availability to range from 64 million green t to 561 million dry t. The largest biomass categories for the U.S. are energy crops and agricultural residues, while for Canada they are expected to be energy crops and logging residues. The significant differences in study estimates are due in large part to the number of biomass categories included, whether economic considerations are incorporated, assumptions about energy crop yields and land areas, and level of optimism of assumptions of the study.

OBJECTIVES

This study investigated IQ scores in pediatric concussion (ie, mild traumatic brain injury) versus orthopedic injury.

METHODS

Children (N = 866; aged 8–16.99 years) were recruited for 2 prospective cohort studies from emergency departments at children’s hospitals (2 sites in the United States and 5 in Canada) ≤48 hours after sustaining a concussion or orthopedic injury. They completed IQ and performance validity testing postacutely (3–18 days postinjury; United States) or 3 months postinjury (Canada). Group differences in IQ scores were examined using 3 complementary statistical approaches (linear modeling, Bayesian, and multigroup factor analysis) in children performing above cutoffs on validity testing.

RESULTS

Linear models showed small group differences in full-scale IQ (d [95% confidence interval] = 0.13 [0.00–0.26]) and matrix reasoning (0.16 [0.03–0.30]), but not in vocabulary scores. IQ scores were not related to previous concussion, acute clinical features, injury mechanism, a validated clinical risk score, pre- or postinjury symptom ratings, litigation, or symptomatic status at 1 month postinjury. Bayesian models provided moderate to very strong evidence against group differences in IQ scores (Bayes factor 0.02–0.23). Multigroup factor analysis further demonstrated strict measurement invariance, indicating group equivalence in factor structure of the IQ test and latent variable means.

CONCLUSIONS

Across multisite, prospective study cohorts, 3 complementary statistical models provided no evidence of clinically meaningful differences in IQ scores after pediatric concussion. Instead, overall results provided strong evidence against reduced intelligence in the first few weeks to months after pediatric concussion.

Helene Schjerfbecks Selbstbildnisse – an den Grenzen des Ich
Authors: Landmann Annika
Published: July 2023

Helene Schjerfbeck (1862–1946) ist eine der Ikonen der nordischen Malerei der Moderne. Doch erst seit einigen Jahren findet ihre Kunst auch außerhalb Finnlands und Schwedens Beachtung. Elementarer Bestandteil von Schjerfbecks OEuvre sind ihre Selbstbildnisse. Das Porträtieren der eigenen Gesichtszüge begleitet die Malerin seit den 1870er Jahren bis kurz vor ihrem Tod 1946. Bislang sind etwa 40 Selbstporträts bekannt. In den Werken experimentiert sie mit unterschiedlichen Techniken und Bildfindungen. Das Ergebnis sind selbstbewusste Statements in einem männlich dominierten Kunstbetrieb mit visuellen Referenzen zu Arbeiten von Edvard Munch, Käthe Kollwitz oder Francis Bacon. Schjerfbecks beständiges Changieren zwischen Figuration und Abstraktion erfordert ein Überdenken des konventionellen Porträtbegriffs: Was ist konstitutiv für die Gattung, wenn die äußere Ähnlichkeit zur Porträtierten reduziert wird?

Published: July 2023

Nocardiosis is a rare disease affecting both immunocompromised and immunocompetent hosts, presented in various clinical forms ranging from localized to disseminated infection. Aim of the present study was to investigate the clinical and microbiological characteristics of nocardiosis, antimicrobial resistance profiles, treatment, and outcomes of Nocardia infection over the last 5 years at our institution. The medical records and microbiological data of patients affected by nocardiosis and treated at the university hospital of Heraklion, Crete, Greece, between 2018 and 2022, were retrospectively analyzed. The isolates were identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and through sequencing of 16S rRNA. Antimicrobial susceptibility for 17 agents was determined by E-test and results were interpreted according to CLSI guidelines. Among the 28 Nocardia isolates, eight species were identified, with Nocardia brasiliensis being the most prevalent (32.1%), followed by Nocardia otitidiscaviarum (25%), and Nocardia farcinica (14.3%). Skin and soft tissue infections were the most common presentations, noted in 13 (50%) patients, followed by pulmonary infection presented in 10 (38.5%) patients. Fifteen patients (57.7%) had at least one underlying disease, and 11 (42.3%) were on immunosuppressive or long-term corticosteroid treatment. Susceptibility rates of linezolid, tigecycline, amikacin, trimethoprim-sulfamethoxazole, moxifloxacin, and imipenem were 100, 100, 96.4, 92.9, 82.1, and 42.9%, respectively. The 26 patients in this study were treated with various antibiotics. Mortality rate was 3.8%, and the patient who died had disseminated infection. Since epidemiology and antimicrobial susceptibility are evolving, continuous surveillance is mandatory in order to initiate appropriate treatment in a timely manner.
Controlling electrical circuit of electric motor on igbt transistors
Authors: Shishkin I. , Lushchin Sergii
Published: July 2023

Purpose. Development and analysis of the operation of an electrical circuit for controlling a 700 W direct current electric motor using a contactor on IGBT transistors for operation in diesel locomotives.
Methodology. Analytical and computational methods for developing and analyzing the operation of an electrical circuit using a contactor on IGBT transistors.
Findings. An electrical circuit for controlling a 700 W DC motor using IGBT transistors was developed. The circuit allows you to replace electromagnetic contactors with IGBT transistors to improve the technical characteristics and performance of the electric motor. The use of IGBT transistors allows you to avoid burning of contact groups in comparison with an electromagnetic contactor. A graphical analysis of the transient processes during switching on and off of the electric motor using a circuit based on IGBT transistors was carried out. The analysis of the load characteristic of the electric motor at start-up shows that in the initial section the voltage increases according to a linear law. After the initial increase in voltage, it reaches the set value and the electric motor operates in the operating mode. The analysis of the load characteristics of the electric motor when it is turned off shows, that when the power is turned off, the motor can’t stop immediately, as the phenomenon of self-induction occurs. When the external voltage is turned off, its change on the electric motor occurs according to the exponential law. It is shown that for controlling the operation of the electric motor, it is more appropriate to use an electric circuit based on IGBT transistors, which provides conditions for more stable and safe operation of the electric motor. Using the electrical circuit allows you to find quickly malfunctions for their further elimination. The electrical circuit allows you to avoid physical wear of its electrical elements.
Originality.  An electrical circuit for controlling an electric motor based on modern electronic components has been developed, which allows the use of IGBT transistors instead of electromagnetic contactors. On the basis of the analytical and calculation method and graphical analysis, the expediency of using IGBT transistors instead of electromagnetic contactors has been proven.
Practical value.  The developed electrical circuit can be applied to control a 700 W direct current electric motor for operation in diesel locomotives. The proposed electrical circuit allows to increase the mobility of repairs in the event of a malfunction by replacing the corresponding unit.

The work investigates the possibility of using beetroot powder and chard puree in the technology of sponge cake with reduced gluten content. Reducing the gluten content in the sponge cakes was achieved by using wheat flour with a reduced protein content (8.2 %), beetroot powder and chard puree. Beetroot (Beta vulgaris L.) and chard (Beta vulgaris var. cicla) are sources of fiber, minerals, flavonoids, alkaloids, triterpenes, carotenoids, saponins and betalains, but semi-finished products from beetroot and chard have not yet been used in the technology of flour confectionery. Wheat flour in the experimental samples was partially replaced by beetroot powder in different proportions (5, 10, 15 and 20 % w/w). Egg products, which are allergens, have been partially replaced by chard puree in different proportions (10, 15, 20 and 25 % w/w). Sponge cake recipe has been determined, which, in terms of the content of nutrients that determine the biological and energy value, as well as sensory properties, is characterized by the most acceptable indicators for dietary flour confectionery products with a reduced gluten content. Chemical composition (content of moisture, protein, fats, carbohydrates, dietary fibers, ash) and energy value of sponge cakes enriched with beetroot powder and chard puree were studied. Adding 15 % beetroot powder and 20 % chard puree to the sponge cake (Sample 3) provides a 36.51 % reduction in fat, a 538.46 % increase in dietary fiber and a 712.5 % increase in ash. Energy value of Sample 3 is 15.76 % less compared to the Control sample. Study was conducted to assess the organoleptic properties of sponge cakes enriched with beetroot powder and chard puree, according to the results of which Samples 3, 4 and the Control sample are characterized by the best indicators. Textural analysis was carried out for indicators of hardness, springiness, cohesiveness and chewiness of sponge cakes. Obtained results made it possible to establish that the addition of 15 % beet powder and 20 % chard puree to the sponge cake recipe (Sample 3) significantly improved the structure indicators (chewiness increased by 2.9 %), compared to the recipe of the Control sample. Results of the conducted research indicate the effectiveness of using beet semi-finished products as potential substitutes for wheat flour and other allergens in confectionery technology. Introduction of the proposed ingredients into the recipe of sponge cakes allows to increase the content of bioactive compounds and ensures a decrease in the content of gluten and egg products.

Traditional technologies and equipment for extraction do not meet the needs of industrial production in the constant increase in the volume of finished products due to the low efficiency of extraction of target components, their high energy consumption and duration. This makes it relevant to search for modern, more effective technologies and equipment, the use of which will significantly increase overall production productivity, reduce overall specific energy consumption, improve the quality of the finished products and safety of processes for the environment. The paper analyzes and generalizes methods for intensifying extraction processes from plant materials. The most effective ways to intensify hydrodynamic processes include methods based on cavitation phenomena.  Transformation and redistribution of energy, which occur during the formation and collapse of vapor bubbles due to the creation of a high difference in pressure, temperature, and potential, contribute to a significant increase in the efficiency of dynamic effects on complex heterogeneous systems during extraction. Cavitation technologies ensure ecological purity and safety of the process, make it possible to accelerate mass transfer processes, activate the extractant, obtain a high yield of biologically active substances (BAS) and maintain their properties. Acoustic and hydrodynamic cavitation are most commonly used. Modern research is conducted in search of new solutions to optimize technologies, as well as improvement of cavitation equipment. Examples of hydrodynamic cavitation devices of static and dynamic types are cylindrical and disk rotor-pulsation devices, valve-type high-pressure homogenizers, pulsating dispersers, centrifugal pumps and Venturi tubes. They are used to intensify the processes at the stages of preparation of plant raw materials, activation of the extractant, as well as the extraction itself. Static-type cavitation devices based on the Venturi tube have a number of advantages in terms of design, technological and economic solution.

Growth hormone (GH) plays a leading role in the regulation of cell and tissue metabolism and growth. Its effects are mediated through the so-called somatomedins, among which the most important is the liver-produced insulinlike growth factor 1 (IGF-1). It has been reported that serum GH levels in liver recipients is related to the clinical transplant outcomes.

Objective: to evaluate the prognostic significance of GH in pediatric liver transplantation (LT).

Materials and methods. The study enrolled 148 children (61 boys) aged 2 to 60 months (median, 8) with end-stage liver disease resulting from biliary atresia (n = 86), biliary hypoplasia (n = 14), Byler disease (n = 15), Alagille syndrome (n = 12), Caroli syndrome (n = 5), and other liver diseases (n = 16, cryptogenic cirrhosis, fulminant and autoimmune hepatitis, Crigler–Najjar and Budd–Chiari syndromes, alpha-1 antitrypsin deficiency, glycogenosis and hepatoblastoma). All the patients were transplanted with the left lateral segment of the liver from a living related donor. GH concentrations were measured by enzyme immunoassay before, at one month and at one year after transplantation.

Results. Median plasma GH levels in children with liver disease were 4.3 [1.6–7.2] ng/mL, significantly higher than in healthy children of the same age at 1.2 [0.3–2.4] ng/mL, p = 0.001, while mean height and body weight were lower than in healthy controls. GH levels decreased significantly after transplantation. At one month and one year later, the levels did not differ from those of healthy children (p = 0.74, p = 0.67, respectively). One month after transplantation, GH concentrations were lower in 1-year survivors than in non-survivors (p = 0.02); the diagnostically significant threshold GH level was 1.8 ng/mL. Prior to LT, plasma GH levels did not differ between 1-year survivors and non-survivors. Children with GH levels below 1.8 ng/mL post-LT were 9 times more likely to survive one year post-transplant than patients with levels above the threshold.

Conclusion. GH concentrations in pediatric liver recipients is a positive prognostic indicator of pediatric LT outcomes.
