Authors: Küçük Onur , Seğmen Fatih , Aydemir Semih
Published: February 2025

Aims: The objective of this study was to investigate whether the incidence and development of pneumothorax in patients hospitalized in the intensive care unit (ICU) with coronavirus disease 2019 (COVID-19) pneumonia is associated with patient prognosis.
Methods: This retrospective, cohort, descriptive study was initiated following approval from the ethics committee. The study was conducted on patients with confirmed COVID-19 pneumonia admitted to the tertiary ICU between March 2020 and March 2022. Data were collected from the patient registry system and ICU files. The patients were divided into two groups: those who developed pneumothorax and those who did not. The factors associated with mortality in the ICU were evaluated by univariate analysis and multiple logistic regression analysis.
Results: The study included a total of 397 patients with confirmed cases of COVID-19 infection and pneumonia who were admitted to the ICU between March 2020 and March 2022. The mean age of the patients was 62±15 years. Of the patients, 56.1% were male. Pneumothorax was identified in 6.8% of patients. In addition to pneumothorax, six patients (1.5%) exhibited pneumomediastinum. The mortality rate was observed to be 40.5% among the total patient population. The mortality rate was 81.5% in the group with pneumothorax and 37.6% in the group without pneumothorax. The median time to mortality was 6 days (range 1–29 days) following the diagnosis of pneumothorax. Pneumothorax alone increased the likelihood of mortality in the ICU sevenfold (OR 7.3, 95% CI=2.70–19.75) and twofold when other variables were taken into account (OR 2, 95% CI=0.57-6.99).
Conclusion: Pneumothorax is a common and fatal complication affecting mortality in patients with COVID-19 pneumonia in the ICU, despite the use of protective ventilation strategies. Particular caution should be exercised in patients receiving respiratory support in the ICU and in patients with a severe inflammatory response.
Secretory Cells in Etlingera elatior (Jack) R. M. Smith (Zingiberaceae): Morphology, Histochemistry, and Essential Oil Composition
Authors: Lee Yee-Ling , Abas Faridah , Ismail Intan Safinar , Ding Phebe
Published: February 2025

Etlingera elatior is a perennial, aromatic herb with attractive flavour and fragrance afforded by organic compounds that are stored and released from specialised structures; however, the secretory structures remain undefined. Thus, this study was carried out to determine the secretory cells in the leaves, inflorescences, and peduncles of E. elatior by using scanning electron and light microscopies. Histochemical tests were performed to localise and ascertain the nature of secretion materials, while gas chromatography-mass spectrometry was used to characterise the composition of essential oils (EO). Findings indicate the presence of a heterogeneous mixture comprising EO, mucilaginous and/or lipophilic substances in the secretory cells. A total of 50 compounds were identified in the EO, with the predominance of alcohol. The presence of several terpenic compounds (α-pinene, (E, E)-α-farnesene, (E)-caryophyllene, E-β-farnesene, (E)-nerolidol) suggests a potential involvement of the secretory structures in plant signalling. The widespread distribution of secretory cells throughout the plant tissues indicates adaptive features of the plant’s secretory system. These cells emerged as the main secretory system of E. elatior that renders the EO.

Published: February 2025

Ovitrap deployment stands as a viable strategy for Aedes mosquito control. This study evaluated the efficacy of an autodissemination ovitrap called AedesTech Mosquito Home System (AMHS), which incorporates pyriproxyfen. The study encompassed laboratory trials. Within the laboratory trials, our investigations unfolded across two species of mosquitoes: Aedes albopictus and Aedes aegypti. Three distinct facets were explored in the laboratory trials: the influence of an attractant on the oviposition, the effect of trap positioning on oviposition, and the selection of oviposition sites. Our laboratory results indicated that the Mosquito Home Aqua (MHAQ) solution with attractant consistently attracted Ae. aegypti effectively (Welch’s Analysis of Variance) F (2,68.66) =5.22, p=0.01). However, its efficacy with Ae. albopictus was suboptimal compared to other treatments (Two-way ANOVA, F=0.16, df=2, p>0.05), highlighting the need for considering additional attractants. Notably, the placement of AMHS exhibited no discernible impact on its attractiveness for both mosquito species (T-test, p>0.05), underscoring the flexibility in trap deployment. The occurrence of simultaneous oviposition choices within the same replicates hinted at the possibility that the existing attractant in MHAQ did not significantly influence oviposition (p> 0.05). Therefore, eliminating the attractant is suggested to reduce the cost of AMHS production. Overall, our investigation underscores the promising potential of AMHS for Aedes control, especially Ae—aegypti and substantiated by robust statistical evidence gleaned from this controlled laboratory study.

Published: February 2025

Phonocardiograms (PCG) provide a non-invasive approach to analyzing heart sounds, making them vital for the early detection of cardiac issues. However, identifying the most effective machine learning models and feature extraction techniques for classifying PCG signals remains a challenge. This study aims to determine the most efficient and accurate combinations of machine learning models and feature engineering techniques for classifying PCG signals, with the overarching goal of enhancing diagnostic capabilities in heart health. Seven machine learning algorithms—Logistic Regression, Decision Tree, Random Forest, Naive Bayes, AdaBoost, XGBoost, and Support Vector Machine (SVM)—were evaluated. Feature extraction methods such as Mel-frequency cepstral coefficients (MFCC), Linear Predictive Coding (LPC), and Short-Time Fourier Transform (STFT) were applied. Model performance was assessed using metrics including accuracy, precision, recall, and F1-score. The study found that advanced models like XGBoost and Random Forest, particularly when combined with STFT and MFCC features, consistently outperformed others. These models demonstrated superior accuracy and F1-scores, although they also introduced higher computational complexity. The results suggest that sophisticated model-feature combinations, particularly involving XGBoost and Random Forest with STFT and MFCC, hold promise for improving cardiac diagnostics.

The aim of this paper is to focus on utilizing deep learning approaches for the building of an intelligent image captioning system. To bridge the semantic gap between the literal depiction of the images and the languages, this combined architecture is employed. The structure of the model is of an encoder-decoder architecture which consists of InceptionV3 CNN for feature extraction and LSTMs with attention mechanism to generate the captions. The complexity of the model is determined based on the usage of the Flickr8K image dataset and it was revealed through the results that it can generate accurate, interesting and appropriate content describing the images. This study has good prospects for the development of framework for learning with multiple modalities especially for usage databases that require content-based searching, image-based data retrieval and usability for users with sight problems. The results show that InceptionV3 Model performs best with BLEU Score of 0.8504 followed by DenseNet 201 with score of 0.8274. Further analysis shows
that the best BLEU score of 0.9172 is attained when the dataset of the best performing model, Inception V3, is split into 75:25 Train:Test and running the model for 50 epochs is done. This resulted in a loss function value of 0.70 for the above-mentioned configuration.

Visio-spatial intelligence skills in non-athletes versus amateur boxers
Authors: Mahlangu S’bongile , Mathunjwa Musa Lewis , Breukelman Gerrit Jan , Millard Lourens
Published: February 2025

Background: Visio-spatial intelligence (VSI) skills, including abilities such as spatial awareness, visual processing, and motor coordination, are crucial for athletic performance, particularly in combat sports such as boxing. Amateur boxers require efficient visio-spatial skills (VSS) to quickly process visual information, track opponents’ movements, and execute precise techniques. However, the extent to which amateur boxing experience enhances VSS remains unclear. This study compared the VSI skills of amateur boxers to those of non-athletes.
Methods: This cross-sectional, observational study recruited amateur boxers and non-athletes in the King Cetshwayo District, KwaZulu-Natal, Republic of South Africa. Participants, aged 18 to 27 years, underwent a detailed optometric screening and VSS tests, including accommodation facility, saccadic eye movements, speed of recognition, hand-eye coordination, peripheral awareness, and visual memory.
Results: The study included 90 participants, consisting of 45 amateur boxers (28 [62%] men aged 18 to 25 years and 17 [38%] women aged 18 to 27 years) and 45 non-athletes (29 [64%] men aged 18 to 26 years and 16 [36%] women aged 18 to 27 years). The mean (standard deviation) age of the boxers was 20.7 (2.2) years, whereas the mean age of the non-athletes was 21.9 (2.4) years (P < 0.05). Amateur boxers were superior in VSS, with marked advantages in accommodation facility, saccadic eye movement, speed of recognition, peripheral awareness, and hand-eye coordination (all P < 0.001). However, no significant difference was found in visual memory (P > 0.05). The greatest difference was observed in speed of recognition (88% higher in boxers), and the least difference was observed in visual memory (4% higher in boxers).
Conclusions: VSS differ between amateur boxers and non-athletes, indicating the importance of these skills for athletic performance. These findings emphasize the potential advantages of boxing training in enhancing VSS, which could impact athletic training and performance-enhancement strategies. This underscores the value of integrating visio-spatial training into athletic programs. The observed superiority of boxers in specific VSS areas has broad implications for theories of sports vision, the selection of appropriate tests, and the development of sport-specific VSS testing protocols. Further longitudinal studies with larger sample sizes are required to verify these findings and assess changes in these skills over time.
A review on retinopathy of prematurity
Authors: Rashidian Pegah , Karami Shaghayegh , Salehi Seyyed Amirhossein
Published: February 2025

Background: Retinopathy of prematurity (ROP) is a leading cause of childhood blindness. It predominantly affects preterm infants with very low birth weights or extreme prematurity. Aberrant retinal vascular development, driven by hyperoxia and hypoxia-induced neovascularization, is central to ROP pathogenesis. This review explores the relationship between maternal health and ROP, evaluates current prevention strategies, assesses innovations in diagnostic and screening technologies, reviews contemporary treatments, and identifies future research directions.
Methods: A literature review was conducted in the PubMed / MEDLINE, Scopus, Web of Science, and Google Scholar databases using related keywords, i.e., “retinopathy of prematurity,” “retinal development,” “pathophysiology,” “vascular growth,” “complications,” “visual outcomes,” “maternal health factors,” “obstetrics,” “preeclampsia,” “risk factors,” “preterm birth,” “corticosteroids,” “oxygen management,” “treatment strategies,” “laser therapy,” “anti-VEGF agents,” “surgical approaches”, and “artificial intelligence (AI)” and targeting English studies published in the last 20 years. Additionally, the references from the selected articles were manually reviewed. Clinical trials, meta-analyses, systematic reviews, case–control studies, case series, narrative reviews, pilot studies, and relevant animal studies were included.
Results: Maternal factors, such as diabetes, smoking, and preeclampsia, along with neonatal factors, such as low gestational age and extreme prematurity, are critical contributors to ROP. Key preventative strategies to reduce the risk of ROP and improve neonatal outcomes include: 1. prenatal care involves screening and managing maternal conditions, providing maternal education, and administering antenatal corticosteroids. 2. Neonatal care encompasses nutritional support, supplementation with essential fatty acids, and regulated oxygen administration. By focusing on these strategies, we can enhance the health of newborns at risk for ROP. Advances in screening, including artificial intelligence (AI)-assisted diagnostics and advanced imaging, are improving early detection. Treatment modalities such as laser photocoagulation, cryotherapy, and anti-vascular endothelial growth factor therapies have shown promise but pose challenges, including recurrence risk and systemic side effects.
Conclusions: ROP continues to pose a major threat to the vision of preterm infants, particularly in regions with limited healthcare resources. Addressing ROP requires multidisciplinary team approaches that integrate obstetric and neonatal care. Preventative strategies, including prenatal care optimization, oxygen management, and nutritional support, are essential. Future efforts should focus on integrating emerging technologies and recent findings to ensure global relevance and currency.

A criação da Comissão do Meio Ambiente e Desenvolvimento Sustentável, em 2004, representou um avanço no campo de agenda de políticas públicas ambientais, a partir da autonomia concedida ao tema. Sendo um espaço destinado ao debate e deliberação sobre política nacional do meio ambiente, direito ambiental, recursos naturais renováveis, flora, fauna, solo e desenvolvimento sustentável, questiona-se: A atuação da Comissão do Meio Ambiente e Desenvolvimento Sustentável, em termos de produção legislativa, corresponde às potencialidades previstas pelo Regimento Interno da Câmara dos Deputados? Para responder a essa pergunta, as prerrogativas constantes no Regimento Interno da Câmara são comparadas com a produção legislativa da comissão durante a 55ª legislatura, presente nos Relatórios de atividades da CMADS, publicados todo ano no site da Câmara dos Deputados. Esses materiais foram classificados conforme o tema das proposições apreciadas e tabuladas em planilhas LibreOffice Calc. Literaturas sobre o ciclo de políticas públicas e formação de agenda governamental dão suporte à pesquisa que conclui que a CMADS tem poder potencial de deliberar sobre modelos de desenvolvimento mais ou menos sustentáveis, mas, na prática, detém-se a temas corriqueiros, que não apresentam ameaça ao modelo de desenvolvimento vigente, através de movimentos de veto players.
Analysis of Pragmatic Terms in Western Political Discourse Intended to Convey a Message to Iraq: US Ambassador's Speech as a Case Study
Authors: Mohammed Mohammed Hayder , Mahdi Mohammed Abbas
Published: February 2025

This study aims to analyze the pragmatic terms used in the U.S. ambassador's speech to identify how these items function to convey particular messages and to assess their impact on shaping Iraqi perceptions of U.S. policies and intentions. Its importance rests in the fact that it can demystify how pragmatic terms mold political communication in the specific framework of Western discourse oriented toward Iraq. Since the fine-grained use of language is being focused on, it can reveal underlying goals and plans that can change public opinions and political results. This study includes some theoretical studies and comments regarding the topic of analysis of pragmatic terms in Western political discourse intended to convey a message for Iraq. This study is qualitative. It analyzes U.S. Ambassador Alina Romanowski's speech about the proposed amendments to Iraq's Personal Status Law. It uses thematic analysis as a method for analyzing qualitative information that includes reading through a set of data and trying to find patterns within the meaning of the information to discover topics. Austin's and Searle's Speech Act Theory is applied to this study. The results clarified the fact of the Eastern pragmatic terms and their functions in conveying certain messages to Iraqi people.

Este artigo buscou analisar as internações por osteomielite no estado do Tocantins entre 2014 e 2023, utilizando dados extraídos da base do Sistema de Informações Hospitalares do SUS (SIH/SUS). O objetivo foi identificar padrões de morbidade, distribuição por faixa etária e sexo, além de avaliar os custos associados às internações. A metodologia consistiu em um estudo epidemiológico retrospectivo, utilizando dados secundários de internações hospitalares. Os principais resultados mostraram que a osteomielite teve maior prevalência em indivíduos do sexo masculino, com a faixa etária de 30 a 39 anos sendo a mais afetada. Palmas foi o município com o maior número de internações, o que pode ser atribuído à sua maior infraestrutura de saúde e à concentração populacional. Quanto aos custos, observou-se um aumento significativo em anos com maior número de internações, destacando a relação entre a carga assistencial e os gastos do SUS. Conclui-se que, embora as internações apresentem variações anuais, é essencial implementar estratégias de prevenção e melhorar o acesso ao tratamento, especialmente em municípios fora da capital, para mitigar os impactos da osteomielite no sistema de saúde pública estadual.

Abstract. Developing operational data assimilation systems for sea-ice models is challenging, especially using a variational approach due to the absence of adjoint models. NeXtSIM, a sea-ice model based on a brittle rheology paradigm, enables high-fidelity simulations of sea-ice dynamics at mesoscale resolution (~10 km) but lacks an adjoint. By training a neural network as an Arctic-wide emulator for sea-ice thickness based on mesoscale simulations with neXtSIM, we gain access to an adjoint. Building on this emulator and its adjoint, we introduce a four-dimensional variational (4D–Var) data assimilation system to correct the emulator's bias and to better position the marginal ice zone (MIZ). Firstly, we perform twin experiments to demonstrate the capabilities of this 4D–Var system and to evaluate two approximations of the background covariance matrix. These twin experiments demonstrate that the assimilation improves the positioning of the MIZ and enhances the forecast quality, achieving an average reduction in sea-ice thickness root-mean-squared error of 0.8 m compared to the free run. Secondly, we assimilate real CS2SMOS satellite retrievals with this system. While the assimilation of these rather smooth retrievals amplifies the loss of small-scale information in our system, it effectively corrects the forecast bias. The forecasts of our 4D–Var system achieve a similar performance as the operational sea-ice forecasting system neXtSIM-F. These results pave the way to the use of deep learning-based emulators for 4D–Var systems to improve sea-ice modeling.

Abstract. The maiden resupply voyage of HMNZS AOTEAROA to Winter Quarters Bay, McMurdo Sound, provided a vessel of opportunity to complete experimentation in the Ross Sea and Southern Ocean, focused on improving maritime safety. The science programs on the voyage included the deployment of 21 free floating wave buoys, 10 Global Drifters, 2 Argo Floats and 85 expendable bathythermograph profilers. In addition, measurements of meteorological and oceanographic conditions and sea ice characteristics were captured from onboard the ship and augmented with satellite-based synthetic aperture radar captures and high-resolution wave modelling. An aligned experiment was also undertaken to assess the performance of Global Navigation Satellite Systems at high latitudes. The full set of voyage data and instructions for their access are described.

The efficiency of potato seed production directly depends on the quantitative yield of standard planting tubers at each stage of reproduction. Therefore, the creation of conditions for active tuberization and the formation of the maximum amount of seed fraction in the cultivation technology is the main factor in increasing the multiplication rate, especially for improved potatoes created by biotechnology. The research aimed to determine the effect of dissolved complex fertilizers and plant growth regulator, when used together, as active factors of potato growth and development, especially in the absence of moisture during critical periods of vegetation. The results of three years of research have shown the advantage of dissolved NPK 16:16:16 at a rate of 5 c/ha and 1 l/ha of Bioglobin over granular NPK 16:16:16 when applied locally. In particular, the leaf surface area increased by 13%, plant height by 3%, tuber yield by 78 thousand pieces per 1 ha, and total yield by 30%. The growth of seed tubers, the main product of the seed industry, averaged 19%. The improved fertilization system for seed potatoes provides a 24% increase in economic efficiency.
