DNA extracted from museum specimens of the 19th century provides a taxonomic resolution on the identity of the characid fish Psalidodon jequitinhonhae (Ostariophysi: Characiformes)
Authors: Queiroz Victor de , Silva Priscilla Caroline , Malabarba Maria Claudia , Weigt Lee , Dergam Jorge Abdala , Malabarba Luiz R.
Published: December 2023

Abstract Psalidodon jequitinhonhae was originally proposed as a variety of Tetragonopterus rutilus, based on the analysis of 14 specimens from the Jequitinhonha River, Brazil. In 1910 it was relocated in Astyanax, as A. fasciatus jequitinhonhae in Tetragonopterinae and in 2020 in Psalidodon, as Stethaprioninae member. However, in none of these revisions, P. jequitinhonhae was morphologically redescribed. A short sequence of the Cytochrome c oxidase subunit I (COI) gene obtained from one of the syntypes is compared to sequences obtained from new samples, allowing the recognition of the species and its morphological redescription based on new specimens. Both morphological and molecular data converged and corroborated P. jequitinhonhae as a valid species, occurring in the Jequitinhonha and Pardo river basins in Brazil. The syntype that provided the analyzed COI sequence is referred to as the lectotype by present designation.

Authors: Tencatt Luiz Fernando Caserta , Grant Steven , Bentley Rebecca Frances
Published: December 2023

Abstract A new species of Corydoras is described from the rio Jutaí, Amazon basin, Brazil. The new species can be distinguished from its congeners by having the following features: (I) ventral surface of trunk entirely or almost entirely covered by small- to relatively large-sized coalescent platelets, forming a typical mosaic-like pattern; (II) large, arched dark brown or black patch extending from interopercle region to posterior process of parieto-supraoccipital, transversally crossing the orbit and forming a typical mask-like blotch; (III) absence of conspicuous dark markings on caudal fin; (IV) absence of longitudinal rows of dark blotches on flanks; (V) region of first dorsolateral body plate surrounding posterior process of parieto-supraoccipital clearly lighter than remaining portions of head, forming a V-shaped pattern in dorsal view; (VI) anterior portion of dorsal fin with a conspicuous dark patch; and (VII) anterior portion of dorsal-fin base with conspicuous concentration of dark brown or black chromatophores, forming a dark patch slightly darker than ground color of body. A discussion on the possible positive adaptive value of the color pattern is also provided.

Published: December 2023

ABSTRACT The search for cultivation techniques that provide productive, social and environmental benefits to the agroecosystem is of great seriousness for the sustainable intensification of agriculture. This study aimed to determine the effect of crop cover crops on the soil attributes and development of bean plants treated with the consortium of bioagents Serratia marcencens + Trichoderma koningiopsis grown in the winter. The experiments were conducted for three crop seasons, in a randomized blocks design arranged in a 2 × 8 factorial scheme, with four replications. The treatments consisted of the combination of eight cover crops with two microbial treatments. The bioagents and the mix of cover crops, especially the treatment 2 (corn) and the mixes 3 (millet, Crotalaria ochroleuca, black oat, white oat, buckwheat and coracana grass) and 5 (black oat, buckwheat, millet, Piatã grass and C. Ocholeuca), provided significant increases in the soil chemical and biological quality, with increases in the contents of Ca, Mg, K, H + Al and organic matter, as well as in the main soil pathogens that affect the bean crop, concerning fallow. In addition, there was an increase in the number of pods per plant and grains per pod. The use of these technologies provided savings, if compared to the use of chemical fertilization.

Published: December 2023

ABSTRACT The biomass sorghum [Sorghum bicolor (L.) Moench] was developed for energy production, but its agronomic characteristics make it an alternative plant for silage production. This study aimed to evaluate the chemical-bromatological composition of silages from biomass sorghum genotypes. The experimental genotypes B004, B005, B009, B010, B011, B013, B015 and B020, as well as three commercially available genotypes (BRS655, Volumax and K1009), were evaluated. The pH, dry matter, ash, organic matter, crude protein, neutral detergent fiber, acid detergent fiber, hemicellulose and lignin were analyzed. A completely randomized design, with four replications, was used, having the genotypes as treatments. Although significant differences were observed among the 11 genotypes, the chemical-bromatological composition of all them showed their potential to be used for silage production.

Published: December 2023

ABSTRACT Objective: To compare and analyze pulmonary function and respiratory mechanics parameters between healthy children and children with cystic fibrosis. Methods: This cross-sectional analytical study included healthy children (HSG) and children with cystic fibrosis (CFG), aged 6–13 years, from teaching institutions and a reference center for cystic fibrosis in Florianópolis/SC, Brazil. The patients were paired by age and sex. Initially, an anthropometric evaluation was undertaken to pair the sample characteristics in both groups; the medical records of CFG were consulted for bacterial colonization, genotype, and disease severity (Schwachman-Doershuk Score — SDS) data. Spirometry and impulse oscillometry were used to assess pulmonary function. Results: In total, 110 children were included, 55 in each group. In the CFG group, 58.2% were classified as excellent by SDS, 49.1% showed the ΔF508 heterozygotic genotype, and 67.3% were colonized by some pathogens. Statistical analysis revealed significant differences between both groups (p<0.05) in most pulmonary function parameters and respiratory mechanics. Conclusions: Children with cystic fibrosis showed obstructive ventilatory disorders and compromised peripheral airways compared with healthy children. These findings reinforce the early changes in pulmonary function and mechanics associated with this disease.

Authors: Sorokina Elena
Published: December 2023

To evaluate a business in the context of the implementation of sustainable development goals, not only financial, but also environmental, social and economic reporting information is required. Various organizations are currently developing recommendations for the preparation of relevant reporting information. There are various approaches and principles business participants can choose from when preparing these reports. However, in practice, such reports are not very useful, since they have different content and terminology and are not easy to navigate. The purpose of the study was to review the content of reports currently available to users interested in business, and to determine recommendations they are based on to establish a trend in resolving reporting issues for sustainable development. We studied, summarized, systematized and analyzed legal framework and recommendations relevant to the topic, as well as the content of thematic sites. We found that in world practice there has been a clear trend to consider reporting as a source of information that determines the value of an organization taking into account its actions in the field of sustainable development. In addition, we highlighted the problem of relevant terminology and possibility of solving it. We concluded that there is possibility of emergence of new corporate reporting based on the principles of integrated thinking, and provided its definition.

Published: December 2023

The study examined the tax revenues of local budgets during the coronavirus pandemic. The data on the budgets of urban districts of the Irkutsk region were taken as the basis for the study. We identified main development trends, factors that had the greatest impact on changes in the volumes, structure of tax revenues, and their correlation with other types of local budget revenues. All the studied urban districts of the Irkutsk region are in different economic, climatic and other conditions of development, which made it difficult to draw general conclusions, but, despite this, general trends were identified. The structure of tax revenues of local budgets mainly changed under legislative reforms introduced during this period. The specifics of local taxes received by the budgets of urban districts contributed to the fact that their volume was practically not affected by the negative factors associated with the coronavirus pandemic. We analyzed and assessed the indicators of the budget revenues of the city of Irkutsk, which is the regional center. The conclusions made for this municipality can be applied to other urban districts of the Irkutsk region, taking into account the specifics of their development.

Authors: Li Mengmeng , Ji Hongchao , Han Chun , Liu Shengqiang , Xiao Wenchao
Published: December 2023

The corrosion behavior of galvanized X80 pipeline steel welded joints in a marine atmospheric environment was studied using the cyclic salt spray accelerated corrosion test. The corrosion weight loss, corrosion morphology and corrosion products of samples under different cycles were characterized by means of appearance inspection, SEM and EDS. The results show that with the rupture of the galvanized layer, cracks first appear when the weld metal is exposed for eight days. With the infiltration of the corrosive liquid, pitting pits first appear in the weld metal. In the early stage of corrosion in the heat-affected zone, the fracture degree of the zinc layer is more serious than that in the other two areas. The corrosion products of the zinc layer accumulate irregularly and more pits appear, resulting in early cracks and pitting pits in the later stage. Compared with the first two regions, the base metal shows better corrosion resistance.

RELEVANCE OF COLD-ROLLING TECHNOLOGY FOR THE TEXTURE AND ANISOTROPY OF EN AW-8011A ALUMINUM ALLOYS
Authors: Kraner Jakob , Kim Kyung  Il , Kim Bonghwan , Kim Shae K. , Paulin Irena
Published: December 2023

The combined effects of the reduction ratio and annealing conditions during cold rolling were investigated for the texture and anisotropy of an EN AW-8011A aluminium alloy. To characterize the microstructural and textural differences, a scanning electron microscope with electron back-scattered diffraction was used. To achieve low anisotropy, the three key factors of texture were exposed: a low fraction of deformed grains according to the average grain misorientation, a large amount of random texture components and the equivalent ratio between deformed and recrystallised texture components. The results of crystallographic texture analysis and anisotropy values revealed that the higher ratio of total cold deformation (cold rolling reduction) and the higher ratio of cold deformation after the intermediate annealing were more favourable for the final continuous annealing in terms of decreasing anisotropy. In contrast, the lower ratio of the cold deformation resulted in lower anisotropy when implementing batch annealing.

Authors: García Ramírez Yasmany Damián
Published: December 2023

The process of conducting research represents only a portion of the overall scientific work. It is complemented by the tasks of writing the scientific article, its publication, and in the future, its citation. The scientific article is a very common way of sharing knowledge. It is the product of a research process in which relevant results are obtained to be presented. This entire process can be exhausting and even frustrating when it comes to scientific publications, especially in the field of engineering, where less importance is often given to writing. Therefore, the aim of this document is to explain the basic steps for writing a scientific article in engineering. The main sections of an average article are developed, and some recommendations are highlighted to facilitate its writing. Although it is focused on engineering, some of these sections can be used in other areas of knowledge. In addition, they can be useful in writing professional reports, as they offer advice for effectively communicating a completed work.

The goal of this project is to create a protein-rich beverage based on whey and various amounts of pulp from the Fragaria fruit (strawberry). The whey was physicochemically characterized, and three beverage formulations with varied percentages of strawberry pulp (10, 25, and 40% w/w) were created. The hydrating beverages obtained were tested for pH, acidity in lactic acid and consumer sensory acceptability. The three formulations meet the physical and chemical standards described in NTE INEN 2609:2012 for whey beverages, and statistical analysis reveals no statistically significant changes between treatments. An untrained panel carried out the sensory evaluation where the main organoleptic characteristics were taken into account. The 60% whey and 40% strawberry beverage received the most approval, while taste was the highest ranking element.

This article presents results, analysis and discussion derived from research made in a Computer Programming course in Systems and Computer Engineering whose objective was to establish comparative criteria that would capitalize the advantages of Connectivism with windows of time, as a learning instrument, in front of traditional methodology of evaluation by individual written exams. We proceeded to work forming two subgroups so that each one responds to a different methodology of evaluation to then compare them quantitatively and qualitatively. The results show great favorability towards the evaluation methodology supported in Conectivismo. It is concluded that, in a controlled environment, taking advantage of the options provided by the Connectivism, it is possible to achieve the motivation required for a more effective, more lasting learning and more tuned to the natural language of today's young people: technology.

Published: December 2023

Epithelial ovarian carcinoma is the most common type of all the ovarian cancers. The patients with advanced stage are initially treated with neo-adjuvant chemotherapy followed by interval debulking surgery. The high mortality rate is mainly due to advanced stage disease at initial presentation.

This a retrospective study carried out in department of pathology at Bhagwan Mahaveer cancer hospital, Jaipur. The retrospective cases data was collected and analyzed from patient records on basis of inclusion and exclusion criteria.

: Patients of advanced ovarian cancer with fibrosis grade 3, necrosis grade 2, presence of psammoma bodies, presence of collagen deposition, low Ki67 index, positive ER status were associated with longer DFS (p value= 0.014,0.029,0.033,0.028,0.001 and 0.001 respectively) and OS (P value 0.025,0.005,0.002,0.015,0.001 and 0.001 respectively).

We propose that the prognostic histopathological parameters analysed in our study in post NACT patients of ovarian carcinoma should be reported in final histopathological report, as these factors can provide an extra tool for clinicians to optimize patient management and care.

Evaluation of Sustainability Reporting Practices in Indian Banks – A Content Analysis Approach
Authors: Maurya Sushma , Singh Rajinder
Published: December 2023

In present times to achieve sustainable development, business organisations are required to disclose their socio-environmental contribution along with their financial results and to incorporate sustainability into their business practices. This paper with the help of content analysis seeks to analyse the sustainability disclosures of selected Indian banks listed on BSE for the year 2019-20. It further examines any significant difference in the sustainability disclosure of selected banks based on their sustainability disclosure according to the Global Reporting Initiatives (GRI) framework, foreign market presence and ownership pattern. As per the results of content analysis, the study finds that Sustainability Reporting (SR) is lowest for the ‘Environment’ dimension followed by ‘Human Rights and Labour Practices’ while reporting under the ‘Governance’ dimension is highest. The ‘Social’ dimension is also fairly reported by the sample banks. The results of Mann Whitney U test indicate that sustainability disclosure is significantly different among selected banks based on the adoption of the GRI framework for sustainability reporting and no difference in SR is found based on ownership pattern and foreign market presence.

From the papers in this special issue it can be concluded that an environmentally sustainable transport system is attainable with a broad-based and concerted commitment. Environmentally sustainable transport will result in significant changes in the type of passenger and freight transport provided, but this does not lead to economic collapse. Important challenges lie in the acceptability of the goals, targets, and strategies and their component instruments.
The realisation of the 80% CO2-emission reduction target for the transport sector can be concluded to be the most ambitious one. If the CO2 emission reduction target for the transport sector is assumed to be lower, or the time period for implementing EST longer, the contribution of technological changes to attaining EST is likely to increase, thus decreasing societal impacts and increasing public support. Moreover, recent model studies indicate that global greenhouse gases can - in accordance with the EU climate objective - be effectively reduced by 20%, compared to current levels, by 2040 (i.e. a 50% decrease compared 2040 to baseline projections) through global cap-and-trade emission trading systems and carbon taxation (on average about 100 euro per tonne of CO2) (Bollen et al., 2004). These taxation levels do not strongly affect the transport sector, as other sectors may provide CO2 emission reductions at far lower costs (Van Rompuy et al, 2003).
However, it is difficult to imagine that significant reductions in climate change emissions in the post Kyoto era are attained without efforts to reduce emissions in the transport sector. The EST studies for Germany, the CEI countries and also Sweden show that encouraging environmental, societal and economic impacts can be achieved with an extension of the time period (50% emission reduction by 2030) to allow transition towards EST.
Mundo y trascendencia: apuntes sobre la dimensión ontológica del juego en Carlos Astrada y Eugen Fink
Authors: Mauna Florencia
Published: December 2023

Dentro de la academia los estudios sobre el juego suelen ser marginados o subestimados como cuestiones secundarias al pensamiento, o como espacios de discusión dirigidos solamente al ocio contemplativo. Sin embargo, en oposición a este tipo de inferencias nos dedicaremos enteramente a reivindicar el papel del juego como fenómeno existencial fundamental en la pregunta por el ser y su relación con el mundo. En el presente trabajo propondremos un cruce lúdico y metafísico entre dos reconocidos pensadores: Carlos Astrada, filósofo argentino, y Eugen Fink, filósofo alemán. Ambos autores comparten la herencia heideggeriana que pondrán en discusión y que servirá como hilo conductor del diálogo teórico sobre el carácter ontológico del juego.
Efficiency Improvement of Photoelectrochemical Solar Cell Applications by Using Ternary Hybrid MoS2/g-C3N4/Cu2O
Authors: Abdurrahman Muhammad , Burari Felix Wilfred , Haque MD Fazul , Olasoji Okunola Wilson
Published: December 2023

In this paper, molybdenum disulfide MoS2 was hybridized with graphene carbon nitrite (g-C3N4) and Cu2O in order to enhance the photoelectrochemical (PEC) activity and increase the light absorption range of Cu2O thin film. The melamine powder was poured in an empty container and then heated in a furnace to attain the powder. The ternary hetero-epitaxial growth was achieved by growing of MoS2/g-C3N4 on the Cu2O hybrid by a partial thermal oxidation process. The characteristics of MoS2/g-C3N4/Cu2O hybrid film were investigated through XRD, FT-IR and photoelectronchemistry-related measurements. The PEC behavior of the ternary hybrid electrode was investigated using current-voltage test under illumination. The efficiency calculated from current-voltage test under illumination shows that the presence of graphene carbon nitrite and molybdenum disulphide within the film networks, despite its low content, could stimulate substantial improvement in maximum photoconversion efficiency from 0.036% to 0.33%. This improvement is attributable to the enhancement of the electron-transferring proficiency upon the insertion of g-C3N4 and, MoS2 as confirmed by X-Ray Diffraction Analysis (XRD). The PEC test results signify that the photoelectrochemical activity of the MoS2/g-C3N4/Cu2O ternary hybrid is much higher than that of subtrate. The mechanisms accountable for the enhanced PEC behavior of the MoS2/g-C3N4/Cu2O ternary hybrid are discussed in detail.Keywords: Cuprous Oxide, J-V Characteristic, Hetero-structure, Photoelectrochemical, Thermal Oxidation.
Research of Two-Modulus Weighted Codes with Summation Involving Arbitrary Partitions of Several Data Symbols
Authors: Efanov Dmitriy , Timoshenkov Maksim , Sivachenko Leonid , Leskovets Igor'
Published: December 2023

A method has been proposed for constructing two-modulus sum codes that are suitable for solving the synthesis problems of self-checking digital computing devices and systems, as well as the technical means of their diagnostics. In the process of constructing a code, a set of data symbols is divided into two subsets, forming separate vectors for which the total weight is calculated according to a predetermined modulus. Beforehand, in each of the selected vectors, one of the data symbols is weighted with a coefficient from a natural series. Codes obtained with different values of weight coefficients and modulus for determining the total weight form a separate family of uniform binary codes with a fixed number of check symbols. The article provides an example of constructing a sum codes in the ring of residues modulus M = 4. Using this modulus enables the construction of a two-modulus code with k = 4 check symbols for any value of the m number of data symbols. As the value of m increases, the relationship between the number of data symbols and check symbols will change significantly, and the resulting code will have low redundancy. This is important when using the considered class of codes in the construction of digital devices. Previously unknown properties of the discussed class of sum codes have been identified, and taking these into account is beneficial when addressing problems related to the synthesis and technical diagnostics of digital devices.
“You are reminded that you don’t have power”: The victimization of security guards working in Gauteng, South Africa
Authors: Jansen van Rensburg Shandre Kim , Buthelezi Muzukhona , Nkwana Mokata , Msimang Nomsa , Zitha Moitsadi
Published: December 2023

Security guards face victimization in the workplace as well as through the nature of their employment as first responders to criminal activity. Consequently, these risks threaten their job satisfaction, well-being, and turnover rate in the industry. Exacerbating the problem further is the dearth of scientific studies and reliable reports on the victimization of security guards specific to the South African context. Thus, the goal of the study is to explore the victimization of security guards working in Gauteng, South Africa. This paper is informed by 14 qualitative one-on-one interviews with security guards. The narrative accounts provide rich and descriptive data which were thematically analyzed. The findings suggest that security guards experience victimization in terms of their working conditions and crime victimization while on duty. Moreover, the implications of victimization are exposed. Interestingly, a recurring theme throughout the paper is the sense of powerlessness experienced by the participants as substantiated through literature. This paper makes a unique contribution to industry and academia due to the dearth of scientific studies and reports on the victimization of security guards specific to the South African context. Additionally, the paper advocates for working towards sustainable solutions through work engagement, awareness, training, and effective management strategies.
Task identity of outsourced versus core employees in Nigerian financial institutions: exploring the role of employment status
Authors: Nwakanma Chinegbonkpa Hope A.
Published: December 2023

The work environment in Nigerian financial institutions reflects the polarization and segregation of employees into different employment statuses. However, the implications of this on employee task identity are rarely discussed. This study, therefore, examined the difference in the task identity between the outsourced and core employees in Nigerian financial institutions. A cross-sectional survey research design was employed. A total of 359 employees were selected from six commercial banks in Southeast Nigeria using a multistage sampling method. Data was collected using a structured questionnaire. Pearson’s chi-square test was used to analyze data at the bi-variate level, while logistic regression analysis was used at the multi-variate level, all at p<0.05. Outsourced employees experienced a lower level of task identity than core employees. Employment status (OR =5.501, 95% CI 3.051-9.919) and education (OR=2.896, 95% CI 1.329-6.313) were significantly associated with task identity. Banks should design enriched jobs that will enable the completion of entire job functions for all employees without discrimination or favor to any groups or persons, as this will help employees to identify with their tasks when completed and feel pride and important, as well as enhance employee motivation, satisfaction, and commitment.

O trabalho teve como objetivo avaliar a técnica de produção de mudas de tauari (Couratari stellata A.C. Sm.) em tubetes, a partir de plântulas resgatadas da regeneração natural. Um total de 240 plântulas de C. stellata foram coletadas em um fragmento de floresta nativa, situada no munícipio de Carlinda/MT. As plântulas foram repicadas para tubetes de 50 cm³, os quais foram acondicionados em condições diferenciadas para o crescimento das mudas, que constituíram dos tratamentos testados, sendo: T1 – Tubetes em canteiro suspenso (1 m de altura); T2 – ¼ do comprimento do tubete dentro da areia; T3 – ½ do comprimento do tubete dentro da areia; T4 – ¾ do comprimento do tubete dentro da areia. Aos 70 dias da repicagem foram realizadas as avaliações dos parâmetros morfológicos das mudas (número de folhas, altura e diâmetro do caule) e biomassas da matéria seca (total, parte aérea e raízes). As plântulas de C. stellata resgatadas da regeneração natural se adaptaram ao transplante para os tubetes, o que foi comprovado pelas altas taxas de sobrevivência, apresentando 96,7% no T1 e 100% nos demais tratamentos. Conforme o valor de IQD o T1 proporcionou a formação de mudas de melhor qualidade. As técnicas de produção das mudas no T2, T3 e T4 se mostraram viáveis ao crescimento em altura, mas ainda seria preciso manejar as mudas no viveiro, a fim de promover o crescimento em diâmetro e formação de novas raízes.
SAMBA NO INÍCIO DO SÉCULO XX E O MOVIMENTO BREGA NAS PERIFERIAS DO RECIFE: CRIMINALIZAÇÃO E NECROPOLÍTICA

Resumo: o recente projeto de lei de criminalização do gênero musical funk mostra que os movimentos artísticos das periferias são cotidianamente reprimidos, evidenciando a necessidade de estudos nesse campo. Nesse sentido, o presente artigo busca analisar os mecanismos de repressão estatal sobre o samba no início do século XX e sobre o movimento “brega” nas periferias do Recife. Utilizou-se a metodologia comparativa de modo a identificar pontos de convergência e divergência, permitindo a análise de dados concretos e a dedução de elementos constantes, abstratos e gerais. Identificou-se que a criminalização desses movimentos artísticos não está vinculada ao conteúdo artístico, mas no fato de serem manifestações culturais de grupos que estão à margem da sociedade. Concluiu-se que as repressões estatais ao samba durante o início do século XX e ao movimento “brega” de Recife fazem parte de uma conjectura de necropolítica.

Published: December 2023

The characteristics of exhaled aerosols outside the human respiratory airway are of significant importance in understanding virus transmission, yet they remain poorly understood. In order to effectively prevent and control the spread of respiratory infectious diseases, this study numerically investigates the exhaling characteristics of aerosols exhaled from the bronchus or larynx of a human upper airway model. This is achieved using the Euler-Lagrange method and considering various aerosol diameters (dp=0.1, 0.3, 0.5, and 1-20 μm) as well as five expiratory flow intensities (Q=15, 30, 60, 90, and 120 L/min). The important findings of this study are as follows: (1) Expiratory airflow exhibits complex flow phenomena, including jet-flow, flow separations, and vortex structures, with their characteristics being influenced by the expiratory flow intensities. (2) The exhaling characteristics of aerosols vary depending on the combined effects of expiratory flow intensities, virus aerosol diameters, and initial exhaled locations from either the bronchus or larynx. (3) A critical diameter (dc) is identified to represent the size at which aerosols can effectively exit the respiratory airway and potentially pose a transmission risk. This critical diameter is identical for aerosols exhaled from both the bronchus and larynx under the same expiratory flow intensity, but it decreases as the expiratory flow intensity increases. In conclusion, expiratory flow intensity is the most critical factor in determining whether aerosols can be expelled from the respiratory airway, as well as influencing the critical diameter (dc) for aerosols initially located in/after the larynx.

Published: December 2023

Background:

Endocrinopathy is a risk factor for slipped capital femoral epiphysis (SCFE). We aimed to determine (1) the incidence of endocrinopathy-associated SCFE compared with that of non-endocrinopathy-associated SCFE, (2) whether the incidence of SCFE increases with the number of deficient hormones, and (3) the clinical characteristics of endocrinopathy-associated SCFE.

Methods:

We conducted a population-based cohort study using a nationwide database in South Korea. All new diagnoses of endocrinopathy or SCFE between 2002 and 2019 in children born between 2002 and 2005 were identified. The incidence of SCFE was calculated for each type of endocrinopathy. The trend of the incidence of SCFE relative to the number of deficient hormones was analyzed. The male:female ratio was compared between endocrinopathy-associated SCFE and non-endocrinopathy-associated SCFE. For endocrinopathy-associated SCFE, the time between the diagnoses of SCFE and endocrinopathy was evaluated.

Results:

The incidence of SCFE was higher in children with endocrinopathy than in those without endocrinopathy (37.1/100,000 versus 9.0/100,000 children) (relative risk, 4.1 [95% confidence interval, 2.8-6.1]). Among various endocrinopathies, growth hormone deficiency showed the highest incidence of SCFE (583.8/100,000 children). The Cochran-Armitage test showed a linear trend, with an increased number of deficient hormones being associated with a higher incidence of SCFE (p < 0.001). Male sex was dominant in the non-endocrinopathy-associated SCFE group (73%; 117 of 161), whereas female sex was dominant in the endocrinopathy-associated SCFE group (53%; 16 of 30) (p = 0.009). Twenty-two of the 30 cases of endocrinopathy-associated SCFE were diagnosed after the diagnosis of endocrinopathy, with a median time of 3.6 years between the diagnoses. Six (27%) of these 22 children developed SCFE >5 years after the diagnosis of endocrinopathy.

Conclusions:

The incidence of SCFE was approximately 4 times higher in children with endocrinopathy than in those without endocrinopathy. The risk of SCFE increased with an increased number of deficient hormones. Long-term monitoring of SCFE occurrence in children with endocrinopathies is strongly recommended.

» Biomechanical studies report that thin scapular spine (SS) morphology, superiorly placed glenoid components, and increased glenoid baseplate screws contribute to increased acromial and SS strain and may increase fracture risk.

» Clinical risk factors of acromial and SS fractures after reverse shoulder arthroplasty include increasing age, female sex, osteoporosis, rheumatoid arthritis, thin midsubstance acromion morphology, previous acromioplasty, and surgical indication of cuff tear arthropathy.

» Clinical studies show that, in isolation, excessive humeral lengthening, humeral lateralization, and glenoid medialization may increase risk of acromial and SS fractures.

» Biomechanical studies suggest that a combination of glenoid medialization and humeral lateralization (MG/LH) may reduce fracture risk, although this requires clinical correlation.

» Surgeons might reduce fracture risk in patients of high-risk groups by guarding against excessively lengthening the humerus, using a MG/LH prosthesis, and targeting screws to avoid the scapular notch and base of the SS.

Published: December 2023

Is the analytical framework used by ethologists sufficient to study the mental states of non-human animals (NHAs) at the appropriate level of complexity? To address this question our strategy was to i) reveal the experimental and analytic habits of scientists of different disciplines in the literature, and ii) use "intention" as a vector in an interdisciplinary prospect of the study of NHAs mental states. Our own intention was to outline the specific orientations and possible impasses of the ethological analytical framework which limits the consideration of NHAs intentions. We conducted a bibliometric analysis of the scientific literature published between 2016 and 2020 in two steps: 1. through a first corpus, we identified the terms used in studies of NHAs intentions and 2. on this basis, 111 articles related to intentions in NHAs were selected. By analysing them using a co-occurrences network of the authors’ keywords, ten scientific approaches to intention in NHAs were identified. Our main findings are that i) the term « intention » is very seldom used in studies of NHAs; ii) approaches developed in humans are rarely transposed in these studies; and iii) in such few studies, it is not the NHAs intentions which are under question, but the link between NHAs and human intentions. This study highlights the limitations of the current theoretical framework used to study non-human animals’ cognition, which does not allow for the full spectrum of non-human cognitive specificities.
The association between polymorphism of methylenetetrahydrofolate reductase C677T and bronchial asthma in children: a meta-analysis

Published: December 2023

Background: The methylenetetrahydrofolate reductase (MTHFR) gene encodes the folate cycle enzyme involved in folate metabolism. Several studies have revealed the effects of the MTHFR C677T polymorphism in child asthma, but the results were inconsistent.
Objective: We intends to systematically evaluate the association between MTHFR C677T polymorphism and child asthma in the existing studies.
Methods: We performed a comprehensive and systematic search of PubMed, Web of Science and CNKI database, and six studies were finally included in this meta-analysis to determine whether MTHFR C677T variant contributed to the risk of asthma in children.
Results: Pooled data indicated that the MTHFR C677T polymorphism significantly increased asthma risk in children by the random-effects model (odds ratio (OR) = 2.06, 95% confidence interval (CI) = 1.33–3.19). In the subgroup analysis stratified by ethnicity, increased risk was found in Asians (OR = 2.24, 95% CI = 1.39–3.62).
Conclusion: Our meta-analysis demonstrated a definite correlation between MTHFR C677T polymorphism and asthma risk in children.
