Carbon Nanotubes (CNTS) and Frankincense Nanoparticles as Promising Insecticides to Control Onion Thrips
Authors: ALİ Abdulla , JAWAD Sahar , MOHAMMED Akram
Published: December 2023

Thrips tabaci Lindeman (Thysanoptera: Thripidae) is one of the most common and devastating onion pests which is capable of causing substantial harm to onion crops. Synthetic pesticides are mainly used to control onion thrips. T. tabaci requires alternative, low-impact control measures since there are numerous difficulties with utilizing chemical pesticides, including pesticide resistance. This study aimed to evaluate the effectiveness of the nanomaterial compounds on adults and nymphs of the T. tabaci in vivo and study their physiological changes caused by pesticides. The findings demonstrate that using nanomaterials, such as carbon nanotubes (CNTs) and frankincense nanoparticles (FNPs), significantly impacts the number of onion thrips. It also has the potential to lower the risk of pesticide resistance. According to the preliminary results, using carbon nanotubes (CNTs) considerably increased the mortality rate of adults and nymphs of T. tabaci and decreased egg-hatching success. Carbon nanotube (CNTs) and frankincense nanoparticles showed a high death rate in adult and nymphal stages at a concentration of 0.05 percent. Carbon nanotubes (CNTs) demonstrated exceptional mortality rates in adult and nymphal stages, with 90 and 50 percent at 5 mg/mL concentrations. Frankincense nanoparticles (FNPs) treatment demonstrated a high adult mortality rate of around 60 percent compared to the control treatment. Eggs of onion thrips showed different hatching success rates after treatment with CNTs and FNPs. The egg hatch rate did not exceed 40 percent of hatched eggs in the CNTs treatment compared to 90 percent in the control treatment. On the other hand, number of laid eggs per female did not differ significantly, indicating that none of the treatments affected the fecundity of the females. The ability of thrips to develop resistance to CNTs and frankincense compounds requires additional investigation. These natural products could be a suitable alternative to control destructive pests like onion thrips.

Authors: ÖZKİL Mine , ÜREMİŞ İlhan
Published: December 2023

Akdeniz Bölgesi tarım alanlarındaki önemli yabancı ot türlerinden olan Ipomoea triloba L. (IPOTR) ve Convolvulus arvensis L. (CONAR)ˈin mücadelesine yönelik olarak tohumların canlılık oranlarının zaman içerisindeki değişiminin belirlenmesi ve çıkış derinliklerinin saptanması çalışmanın amaçlarını oluşturmaktadır. Çalışmada CONAR ve IPOTR tohumlarının optimum çıkış derinliğinin belirlenmesi için, yabancı ot tohumları 30 °Cˈye ayarlı iklim odasında, toprak+ torf+ kum karışımı bulunan saksılar içerisine 2, 5, 10, 15 ve 20 cm derinliklerine 25ˈşer adet konulmuştur. Değerlendirme için 7, 14, 21 ve 28. günlerde toprak yüzeyine çıkan bitkiler sayılmış, çıkış yapan tohumlar dışarı alınmış ve çıkış yüzdesi hesaplanmıştır. CONAR ve IPOTR türlerinin topraktaki yaşam sürelerinin belirlenmesi amacıyla yapılan çalışmada; her iki yabancı ot türü için 10 ve 20 cm derinlikte çukurlar hazırlanmıştır. Toprağa gömülen her torba içerisine 0.25 kg sterilize edilmiş toprağa 300ˈer adet tohum konulmuştur. Toprağın 10 ve 20 cm derinliğine gömülü tohumlar gömülme tarihini takip eden 6, 12, 18, 24, 30. aylarda tohumların canlılıklarının belirlenmesine yönelik çimlenme denemeleri yapmak üzere tohumlar kullanılmıştır. Her iki türün tohumlarında en iyi çıkışın 2 cm derinlikte gerçekleştiği ve çıkış oranının CONAR için %84.00, IPOTR için %96.80 oranında olduğu belirlenmiştir. CONAR tohumlarının topraktaki yaşam süreleri, toprağın 10 ve 20 cm derinliklerinde, sırasıyla 6. ayda %90.10 ve %87.50 olarak belirlenirken, 30. ayda %15.40 ve %9.50; IPOTR’de ise 6. ayda %93.90 ve %85.20; 30. ayda %10.10 ve %7.60 olarak tespit edilmiştir. Çalışma sonuçlarına göre CONAR ve IPOTR ile mücadelede derin toprak işlemesi yapılarak tohum çimlenmesinin/çıkışının azaltılabileceği ve bu sayede yoğunluğun azaltılıp yeni tohum oluşumunun engellenebileceği değerlendirilmektedir. Ülkemizin pek çok bölgesinde görülen ve ekonomik zarara sebep olan CONAR ve IPOTR ile mücadele yöntemleri içerisinde, toprak işlemenin kullanılabileceği ve üreticilere fayda sağlayacağı düşünülmektedir.
Germination and Seedling Properties of Lotus corniculatus L. Under Simulated Drought Stress
Authors: BEYAZ Ramazan
Published: December 2023

Drought is an important abiotic stress factor that reduces agricultural production and yield in many crops, including forage crops, in agricultural areas around the world. Lotus corniculatus L. is the agriculturally crucial perennial legume forage crop that can tolerate moderate drought. However, studies to determine the responses of L. corniculatus to drought are limited. Therefore, this study was carried out to determine the seed germination and early seedling growth properties of L. corniculatus at different PEG6000 induced-drought treatments under in vitro conditions. In order to do this, L. corniculatus (cv. ‘AC Langille’) seeds were planted in MS (Murashige and Skoog/Gamborg) medium containing 0%, 4%, and 8% (w/v) PEG6000 for 14 days. In this study, germination percentage, mean germination time, germination rate index (speed of germination), shoot and root length, root to shoot length ratio, shoot and root fresh weight, shoot and root dry weight, shoot and root dry matter ratio, root shoot dry matter ratio, shoot and root water content and seedling vigor index parameters were measured. Our results showed that increasing drought levels resulted in an overall significant reduction in germination and seedling growth parameters except shortened mean germination time (especially, 4% PEG6000 treatment) and increased shoot and root dry matter ratio at higher (especially, 8% PEG6000 treatment) drought levels. When important growth parameters such as length, fresh and dry weight, dry matter ratio and water content, which show the development of root and shoot organs, are evaluated together, it has been determined that the root is negatively affected by drought stress at a higher rate. Based on these data, it can be concluded that the L. corniculatus will suffer a high yield loss under the drought stress at the osmotic potential (-1.03 bar) created by 8% PEG6000 treatment.
Evaluation of the Impacts of Climate Change on Sunflower with Aquacrop Model
Authors: GÜRKAN Hüdaverdi
Published: December 2023

Climate change has become one of the most significant risk factors in agricultural production. Plant productivity declines caused by climate change pose a serious threat to food supply and security. Crop simulation models have been widely used in recent years for the assessment of the impacts of climate change on agricultural production. In Konya, there have been limited studies on the potential effects of climate change on sunflower production. Sunflower, the main crop of the most imported agricultural product group, in which the production amount is currently insufficient to cover domestic consumption demand, is strategically important for the Turkish economy. The goal of this study was to examine the effects of climate change on sunflower yield in Türkiye by using the Aquacrop model. The data of the field experiment carried out on the Ekllor sunflower cultivar for two years in Konya conditions were used as material. The daily projection dataset of three Global Climate Models (HadGEM2-ES, MPI-ESM-MR, GFDL-ESM2M) and two scenarios (RCP4.5 and RCP8.5) were used to analyze climate change impacts. The 1971-2000 period was considered as the reference period and the 2022-2098 period was selected as the future period. The results confirmed that the Aquacrop model was able to satisfactorily simulate yield with NRMSE 2.10 % for the rainfed condition and 10.55 % for the irrigated condition, a d-index of 0.97, and a modeling efficiency of 0.91. Aqaucrop climate change impacts simulation which was based on 3 global climate models covering with 2022 -2098 period simulations projected that sunflower yield would be decreased in a range of 21% to 44% for RCP4.5 and 18% to 50% for RCP8.5 scenarios under rainfed conditions. In contrast, the yield would be increased in a range of 11% to 23% for RCP4.5 and 10% to 33% for RCP8.5 scenarios under irrigated conditions. The findings point to the use of appropriate water management measures for future sunflower production as a means of adapting to climate change.
Material type affects the community composition and abundance of hard-substrate assemblages in a sedimentary Atlantic estuary
Authors: Oxley CC , Jurgens LJ
Published: December 2023

Hard-substrate epibionts have an important role in estuaries; they improve water quality, form habitat, and influence food webs. Coastal urbanization converts natural hard substrates (e.g. oyster reefs and rocky shorelines) into artificial structures, which do not support the same hard-substrate communities. Material composition may be a driving factor behind this difference, so interest is growing in how material type can be used to create marine structures that serve an ecological role. However, this research has mainly been restricted to rocky shorelines. We address this gap by asking how material type affects hard-substrate assemblages in a sedimentary Atlantic habitat. We deployed panels of wood, PVC, and 2 different concrete mixes in Galveston Bay, TX, USA, for 3 mo. Unique communities formed on different materials, which may alter ecosystem services if scaled to large development projects. Material type had a limited effect on richness but strongly affected total cover and biomass, both of which are important metrics for ecosystem function. Across all measures, one concrete mix showed the most potential to serve a beneficial ecological role. Our findings highlight the importance of material type in the design of marine structures in sedimentary Atlantic habitats.

Authors: PEKER Hüseyin , ESTEVES Bruno , AYATA Ümit
Published: December 2023

American walnut (Juglans nigra L.) wood is used for veneer due to its beautifully grained and dark-colored wood. This study was conducted to test the use of plant waste oils as color modifiers on American walnut wood. As waste vegetable oils, discarded walnut, olive, corn, and sunflower oils were employed. After applying waste oils to the wooden surfaces, several surface properties (brightness, color, and whiteness index: WI*) were determined. It was observed that multivariate analysis of variance tests conducted for WI* values and color parameters were found to be statistically significant. For all vegetable waste oils, decreases were identified in L*, C*, ho, and b* parameters, as well as in WI* values and glossiness values (for all degrees and orientations). The ∆E* values were measured at 19.18 for sunflower, 22.02 for walnut, 22.65 for corn, and 19.49 for olive. Each of the discarded vegetable oils had an impact on the color of the wooden surface.

Published: December 2023

Las sociedades Cooperativas de Energía están cambiando la realidad del sector energético. Esto es un tema incipiente de investigación que da lugar a una emergente e invisible estructura cientifica. Conocer a esta estructura puede originar unas oportunidades y un apoyo de referencia. A partir de este objetivo y mediante un análisis de red (UCINET-6), se construyeron tres redes: las personas autoras, los centros de afiliación y los países donde radican los trabajos académicos sobre las cooperativas de energía. Se analizaron 47 aportaciones, 24 fuentes, 113 personas autoras pertenecientes a 79 centros de investigación ubicados en 20 países. Los resultados indicaron que los personas autoras suelen cooperar en la producción científica, aunque la colaboración es local, pues ella se origina entre personas pertenecientes a mismos centros y países. Se halló una estructura de red fragmenta y centralizada donde 10 personas científicas son responsables de una producción específica.

Grounding Basic Equality
Authors: Orr James
Published: December 2023

Although egalitarianism has been the dominant orthodoxy in Anglophone social and political philosophy for many decades, there have been surprisingly few attempts to account for the axiom on which it rests, namely that human moral worth does not come in degrees. This article begins by rehearsing and evaluating two families of approaches to the grounding problem. The first favours accounts that seek to preserve consistency with metaphysical naturalism, while the second relies on more philosophically contentious claims about the metaphysical status of the human person. I then outline reasons for supposing that none of these accounts of basic equality offers a convincing theoretical foundation for egalitarianism. I conclude by sketching permutations of a theological account before arguing that one of these variations satisfies many of the explanatory criteria that a successful solution requires.
ANÁLISE DA RELAÇÃO ENTRE A FORMAÇÃO DO PROFESSOR DE PORTUGUÊS E A UTILIZAÇÃO DO GÊNERO DO DISCURSO LIVRO DIDÁTICO EM SALA DE AULA
Authors: Da Silva Silvio Ribeiro , Alves Filho Sebastião Carlúcio
Published: December 2023

A formação do professor de língua portuguesa tem sido alvo de diversos trabalhos acadêmicos, cujo foco, geralmente, está em se buscarem falhas as quais possam interferir negativamente na atuação do futuro professor quando este ocupar a sala de aula. Neste artigo, no entanto, discutimos as possíveis influências que a formação do professor pode exercer sobre o modo como este lida com um gênero do discurso que circula na esfera escolar e pode auxiliá-lo a mediar o processo de ensino e aprendizagem: o livro didático de português (LDP). Conforme o recorte apresentado neste artigo, o professor, mesmo com uma formação que lhe dê subsídios para uma prática em sala de aula que contribua positivamente para o processo de ensino e aprendizagem, pode desconsiderar completamente a presença do LDP, ao se ver influenciado por outros gêneros que o levam a repetir práticas mecanicistas de cunho exclusivamente classificatório.

A área da educação está repleta de discursos que vão sendo reproduzidos e disseminados no tecido social, tornando-se verdades absolutas e inquestionáveis. Nesse sentido, este texto tem a intenção de problematizar o discurso dominante do professor como mero reprodutor do conhecimento. Para tal ação, esta escrita utiliza o pensamento teórico-prático de Roland Barthes, a fim de pensar como uma escrita biografemática pode contribuir na formação de um professor autor. A noção de biografema entra como operador de processos criadores por meio da experimentação de uma escrita que vai permitir o inédito, a invenção e a criação de uma vida docente autoral.

Published: December 2023

O ensino de Língua Portuguesa é frequentemente confundido com o ensino de nomenclaturas gramaticais. Contudo, ensinar língua não se resume à conceituação e à classificação de elementos linguísticos, tampouco o conceito de gramática se resume a isso. Nesse sentido, o presente trabalho busca esclarecer a diferença entre ensino de língua e ensino de nomenclaturas gramaticais, refletindo sobre como a gramática está implicada no uso da língua e pode ser explorada nas atividades escolares com vistas ao efetivo desenvolvimento de competências discursivas dos estudantes. O trabalho vem embasado em estudos de Possenti (1996), Neves (2019), Oliveira (2010), Geraldi (2006) e Fiorin (2007), assim como em proposições da Base Nacional Comum Curricular - BNCC (BRASIL, 2018)

A arte no estado de encontros com o processo criativo de Sérgio Moura
Authors: Bressan Regiane , Sirino Salete Paulina Machado
Published: December 2023

Neste artigo, objetiva-se apresentar a arte no estado de encontros com o processo criativo de Sergio Moura, e a mediação entre os artistas e a sociedade para que a potência criativa flua de forma independente. Portanto, consiste na reflexão do seu projeto Artshow, e sobre a urgência de cultivar a sensibilidade criadora com a estranha realidade nacional, e na abordagem de cada um no todo, no coletivo. Dessa forma, o trabalho de Sergio Moura contempla o coletivo carregado de teor crítico devido à persistência em realizar projetos relacionais e vivenciais, frequentemente transitórios, ao longo dos anos no campo artístico em geral, ocorridos durante o período ditatorial militar. Nesse sentido, ao estabelecer um espaço comum para compartilhar desse lugar enquanto sociedade e devolver para o receptor o olhar em volta, seja encontrando semelhanças ou desacordos com a teoria do filósofo Jacques Rancière, pretende-se propor uma leitura da estética relacional na abordagem dos materiais analisados a partir das principais referências: Luise Boeno Malmaceda, Maria José Justino, Artur Freitas e Jacques Rancière.

Ray tracing model for long-range acoustic vortex wave propagation underwater
Authors: Kelly Mark E. , Zou Zheguang , Zhang Likun , Shi Chengzhi
Published: December 2023

The use of vortex waves in multiple environments is of increasing interest for numerous applications including underwater acoustic communications, particle manipulations, and sonothrombolysis. Finite element methods are limited in the range for which the propagation of these vortex beams may be simulated. On the other hand, ray tracing programs simulate well over long ranges, though are generally limited in their ability to resolve the features of a propagating vortex. Methods for overcoming these difficulties in simulating the long-range propagation of such waves in inhomogeneous environments have been developed and employed, though their specific implementation has not been thoroughly discussed. This manuscript provides the methods by which existing ray tracing programs may be used to approximate the long-range propagation of acoustic vortex beams in complex environments.
Assessing body condition scores, weight gain dynamics, and fecal egg counts in feedlot and non-feedlot cattle within high throughput abattoirs of the Eastern Cape Province

Published: December 2023

Introduction

Feedlots have emerged as an ideal mitigation option to pursue sustainable and efficient livestock production. This paper aims to elucidate how the establishment and widespread adoption of feedlots have provided solutions to complex problems of food security, animal welfare, and environmental sustainability.

Methods

An observational cross-sectional study compared fecal egg count per gram (EPG), weight gain, and body condition score (BCS) in feedlot and non-feedlot cattle at high throughput abattoirs. Cattle (n = 120) of different age and sex groups, farms, and breeds were selected from two commercial abattoirs (EA1 and EA2) in the Eastern Cape Province.

Results

At EA1, non-feedlot cattle exhibited higher EPG values (323.3±28.9) than feedlot cattle (73.3±13.3), indicating a potentially greater susceptibility to internal parasitic infections. The similar weight gains between feedlot (298.1±4.7) and non-feedlot cattle (287.16±7.79) were attributed to the sufficient natural pasture in the communally raised cattle. However, body condition scores were significantly (P< 0.05) better in feedlot than in non-feedlot cattle. Nonetheless, the feedlot farms of origin had a significant effect (P< 0.05) on the EPG and body condition score values in EA1, with no significant effect in EA2.

Discussion

Moreover, the negative correlation between EPG and body condition scores highlights that as parasite load increases, there might be a subtle tendency for body condition to decrease. These results underscore the importance of feedlots as an effective management strategy to improve animal health and productivity. Further investigations into the factors driving the differences in non-feedlot cattle are needed for informed decision-making in livestock management and abattoir operations.

Published: December 2023

Focused ion beam-scanning electron microscopy (FIB-SEM) images can provide a detailed view of the cellular ultrastructure of tumor cells. A deeper understanding of their organization and interactions can shed light on cancer mechanisms and progression. However, the bottleneck in the analysis is the delineation of the cellular structures to enable quantitative measurements and analysis. We mitigated this limitation using deep learning to segment cells and subcellular ultrastructure in 3D FIB-SEM images of tumor biopsies obtained from patients with metastatic breast and pancreatic cancers. The ultrastructures, such as nuclei, nucleoli, mitochondria, endosomes, and lysosomes, are relatively better defined than their surroundings and can be segmented with high accuracy using a neural network trained with sparse manual labels. Cell segmentation, on the other hand, is much more challenging due to the lack of clear boundaries separating cells in the tissue. We adopted a multi-pronged approach combining detection, boundary propagation, and tracking for cell segmentation. Specifically, a neural network was employed to detect the intracellular space; optical flow was used to propagate cell boundaries across the z-stack from the nearest ground truth image in order to facilitate the separation of individual cells; finally, the filopodium-like protrusions were tracked to the main cells by calculating the intersection over union measure for all regions detected in consecutive images along z-stack and connecting regions with maximum overlap. The proposed cell segmentation methodology resulted in an average Dice score of 0.93. For nuclei, nucleoli, and mitochondria, the segmentation achieved Dice scores of 0.99, 0.98, and 0.86, respectively. The segmentation of FIB-SEM images will enable interpretative rendering and provide quantitative image features to be associated with relevant clinical variables.

A novel biomimetic dual layered keratin/hydroxyapatite (keratin/HA) scaffold was designed using iterative freeze-drying technique. The prepared scaffolds were studied using several analytical techniques to better understand the biological, structural, and mechanical properties. The developed multilayered, interconnected, porous keratin scaffold with different hydroxyapatite (HA) content in the outer and inner layer, mimics the inherent gradient structure of alveolar bone. SEM studies showed an interconnected porous architecture of the prepared scaffolds with seamless integration between the upper and lower layers. The incorporation of HA improved the mechanical properties keratin/HA scaffolds. The keratin/HA scaffolds exhibited superior mechanical properties in terms of Young’s modulus and compressive strength in comparison to pure keratin scaffolds. The biocompatibility studies suggested that both keratin and keratin/HA scaffolds were cyto-compatible, in terms of cell proliferation. Furthermore, it showed that both the tested materials can served as an ideal substrate for the differentiation of Saos-2 cells, leading to mineralization of the extracellular matrix. In summary, ionic liquid based green technique was employed for keratin extraction to fabricate keratin/HA scaffolds and our detailed in vitro investigations suggest the great potential for these composite scaffolds for bone tissue engineering in future.

Introduction: Inorganic polyphosphate (polyP) is an ancient polymer which is extremely well-conserved throughout evolution, and found in every studied organism. PolyP is composed of orthophosphates linked together by high-energy bonds, similar to those found in ATP. The metabolism and the functions of polyP in prokaryotes and simple eukaryotes are well understood. However, little is known about its physiological roles in mammalian cells, mostly due to its unknown metabolism and lack of systematic methods and effective models for the study of polyP in these organisms.

Methods: Here, we present a comprehensive set of genetically modified cellular models to study mammalian polyP. Specifically, we focus our studies on mitochondrial polyP, as previous studies have shown the potent regulatory role of mammalian polyP in the organelle, including bioenergetics, via mechanisms that are not yet fully understood.

Results: Using SH-SY5Y cells, our results show that the enzymatic depletion of mitochondrial polyP affects the expression of genes involved in the maintenance of mitochondrial physiology, as well as the structure of the organelle. Furthermore, this depletion has deleterious effects on mitochondrial respiration, an effect that is dependent on the length of polyP. Our results also show that the depletion of mammalian polyP in other subcellular locations induces significant changes in gene expression and bioenergetics; as well as that SH-SY5Y cells are not viable when the amount and/or the length of polyP are increased in mitochondria.

Discussion: Our findings expand on the crucial role of polyP in mammalian mitochondrial physiology and place our cell lines as a valid model to increase our knowledge of both mammalian polyP and mitochondrial physiology.
Evidence-based decision-making in speech-language pathology via video-based telepractice—A qualitative video interaction analysis
Authors: Barthel Maria , Wittmar Silke , Borgetto Bernhard , Leinweber Juliane
Published: December 2023

Introduction

In speech-language pathology, there is a constant need to make evidence-based decisions based on the patient's needs and goals, speech-language pathologist's clinical expertise, and external evidence. During the COVID-19 pandemic, it was possible for the first time in Germany to implement video-based telepractice in the outpatient care of speech-language pathology. This study aimed to find out how evidence-based decisions are made in video-based telepractice and what forms of evidence are used.

Methods

Speech-language pathologists who were working in outpatient services recorded their video-based telepractices for the research project. Five recorded video-based telepractices were transcribed using a simple transcription system and video interaction analysis was used to analyze the video recordings based on grounded theory methodology.

Results

Interactions between patients and speech-language pathologists are characterized by evidence-based decisions that can be observed. Speech-language pathologists make decisions based on their clinical expertise, patient-related experiences, and patient self-assessments. There is little evidence of negotiation between patients and speech-language pathologists to make joint decisions. Results showed that speech-language pathologists do not explicitly name external evidence to justify their decisions to patients. Shared decision-making is encouraged by a participative interaction between patients and speech-language pathologists. However, there was a predominant paternalistic interaction in which the speech-language pathologists made decisions on their own. To represent the decision-based interactions between patients and speech-language pathologists in a video-based therapy session, a process model was developed.

Discussion

Evidence-based and shared decision-making are important in speech-language pathology to provide patient-centered treatments. The exchange of information between the patient and the speech-language pathologist is important in order to make joint decisions based on these different levels of knowledge. In this way, the patient becomes an active participant in the digital treatment, in the video-based telepractice. As a result, the quality of care can be improved. Further research should reconstruct the implicit (possible) use of external evidence.

In this work, a framework was developed to access and process raw data from a commercial X-ray Computed Tomography (CT) scanner for research purposes. Our method requires vendor-provided binaries to convert the data to a readable format and also to remove the effect of proprietary beam hardening preprocessing. As a result, custom reconstruction techniques, including beam-hardening corrections algorithms, can be applied. Small region-of-interest CT imaging techniques and different backprojection algorithms were investigated to improve image quality (spatial resolution, noise) with an in-house iterative reconstruction algorithm. For a reconstruction matrix of 512 pixels × 512 pixels, processing times of approximately 2.5 s per slice were obtained using a set of 8 x GPUs. With this framework, high-quality images of high density samples (e.g., minerals) can be obtained with reduced truncation-induced blurring, free of artifacts stemming from the reconstruction process and reduced beam-hardening artifacts.
The paradoxes of inclusion: cognitive and socio-emotional developmental trajectories of deaf and blind primary education students in mainstream and special schools
Authors: Rosas Ricardo , Espinoza Victoria , Martinez Camila , Santa-Cruz Catalina
Published: December 2023

Introduction

Students with special educational needs (SEN) have historically found participating in the regular education system challenging. Since the 1990s, inclusion has been considered the optimal strategy for their development. However, the effects of inclusive education on deaf and blind students are still little studied.

Methods

In the present article, we report the results of a longitudinal study on the cognitive and socioemotional developmental trajectories of 23 deaf and 29 blind primary education students attending mainstream (8 deaf and 10 blind) and special schools (15 deaf and 19 blind). The study was conducted in Santiago de Chile between 2018 and 2019.

Results

Our descriptive results suggest that deaf students attending special schools perform better on most of the variables studied. For blind students, those attending traditional schools generally perform better than those attending special schools. However, in the case of socio-emotional variables, blind students attending special schools tend to show fewer problems. However, almost all of the indicated differences are not statistically significantly different.

Discussion

We then discuss the need to consider the characteristics of each group of students with SEN when defining an adequate educational system for their optimal development.
Performance of invasive, non-invasive, and pharmacological measures by emergency physicians in the German emergency medical services. A retrospective cross-sectional study from the rescue association Südwestsachsen
Authors: Koch Sebastian , Suffeda Michelle
Published: December 2023

Background

Every citizen in Germany is entitled to qualified emergency medical assistance. Due to annually increasing deployment figures and personnel shortages, it is no longer possible to guarantee 24/7 coverage of all emergency physician locations throughout Germany. Relief can be achieved through changes in the supply structures. Professional field analyses are the basis for the further development of training and care structures.

Methodology

All emergency physician deployments of a location in the rescue association Südwestsachsen that took place between 01.10.2022 and 31.01.2023 were retrospectively evaluated. For this purpose, the analogously created deployment protocols were examined with regard to demographic data as well as the invasive, non-invasive and pharmacological measures performed by emergency physicians.

Results

In N = 684 emergency missions, n = 471 (100%) invasive or non-invasive measures were performed by an emergency physician. At n = 383 (81.3%), the most frequently performed invasive measure was intravenous (i.v.) access. There were n = 710 (100%) pharmacological measures performed by an emergency physician. The most frequently performed pharmacologic measure was administration of a full electrolyte solution, with n = 223 (31.4%)

Discussion

Emergency physician interventions do not necessarily involve invasive, non-invasive, or pharmacologic measures. The emergency paramedic learns a variety of invasive, non-invasive, and pharmacologic measures in his or her training and could contribute to the reduction of emergency physician interventions. An adaptation of prehospital care structures based on evidence-based data and an update of the catalog of indications for emergency physician interventions would be elementary for this goal.

Background

Insulin-like growth factor binding protein-1 (IGFBP-1) is considered a decline in polycystic ovary syndrome (PCOS), but it remains controversial that whether such reduction is attributed to obesity.

Aims

This systematic review aims to explore whether IGFBP-1 is reduced in PCOS, and whether such reduction is associated with obesity.

Results

Our pooled study included 12 studies with a total of 450 participants. IGFBP-1 levels in PCOS were significantly lower than that in non-PCOS (SMD (95%CI)=-0.49(-0.89, -0.09), P=0.02). No significant difference in IGFBP-1 levels between patients with or without PCOS classified by BMI. Whilst, stratification by PCOS status revealed a significant decrease in IGFBP-1 in overweight (SMD (95%CI)=-0.92(-1.46, -0.37), P=0.001). When comparing fasting insulin in the same way, PCOS patients had significantly elevated fasting insulin level but not statistically declined IGFBP-1 after classified by BMI.

Conclusion

This meta-analysis provides evidence that the decrease of IGFBP-1 in PCOS was more strongly influenced by comorbid obesity than by PCOS itself. Additionally, contrast to previous findings that insulin significantly suppresses IGFBP-1, our results suggested that the suppression of PCOS-related hyperinsulinemia on IGFBP-1 seemed diminished. Overall, our work may provide a novel perspective on the mechanism between insulin and IGFBP-1 underlying PCOS development.
