Green finance, green development and decarbonization of the energy consumption structure
Authors: Zhu Hui , Feng Tianchu , Li Xiaoliang
Published: April 2024

Energy plays a crucial role in global economic development, but it also contributes significantly to CO2 emissions. China has proposed a “dual-carbon” goal, and a key aspect to achieving this objective is finding effective ways to promote the decarbonization of the energy consumption structure (DECS). Compared with traditional finance, green finance is pivotal in advancing green and low-carbon development. However, the mechanism through which green finance impacts DECS has not been thoroughly explored. This study employs an enhanced weighted multi-dimensional vector angle method, which is more systematic and scientific, to measure DECS. Then, dynamic panel data from 30 provinces in China spanning the years 2003 to 2020 are used. A double fixed-effects model is applied to investigate the impact of green finance on the DECS and identify potential pathways. Results reveal that green finance significantly enhances DECS, primarily by reinforcing green development. The critical impact pathway involves the promotion of green technology innovation and green industry development. Moreover, the enhancing effect of green finance on the DECS is considerably significant in regions with relatively low government spending on science and technology (S&T), and where the focus is not on the “Atmospheric Ten” policy. The measurement of DECS is innovative, and the conclusions derived from it can offer compelling evidence for various social stakeholders. The government has the opportunity to establish a green financial system, supporting green technological innovation and the development of green industries. This approach can accelerate the DECS and work toward achieving the “double carbon” goal at an earlier date.
Introducing re-weighted range voting in clinical practice guideline prioritization: Development and testing of the re-weighted priority-setting (REPS) tool
Authors: Oerbekke Michiel S. , Gaasterland Charlotte M. W. , van der Laan Maarten J. , Hooft Lotty
Published: April 2024

We aimed to develop and test a tool based on the re-weighted range voting mechanism to prioritize items (i.e. key questions) in a priority-setting assessment for clinical practice guidelines. The secondary aim was to provide methodological context of the tool. We iteratively developed the tool and used qualitative methods (i.e. think-aloud and semi-structured interviews) to test the tool’s usability and make adjustments accordingly. An observational approach was used to test the tool’s outcome satisfaction in a real-world priority-setting assessment within a rare-disease guideline of a European Reference Network and under four different conditions in the tool. Four guideline methodologists tested the usability of the tool. The real-world testing was performed with a guideline panel consisting of a core working group, five expertise working groups, and a working group with patient representatives. Thirty-one panel members assigned scores in the priority-setting assessment. Seventeen panel members rated the priority-setting outcome, and sixteen panel members rated the outputs generated under the four conditions. Upon initial use, guideline methodologists found the tool to be quite overwhelming. However, with some initial effort they were able to easily identify the tool’s structure. Based on observations and feedback, the tool was further refined and user guidance was developed. Guideline panel members expressed (high) satisfaction with the priority-setting outcome. They particularly preferred the condition when using mean subgroup scores as input or employing aggressive penalties in the weighting method to determine the outputs. The tool generates a ranked list of items and offers flexibility for different choices in priority-setting assessments as long as its input format requirements are met. Although it is not a consensus method, the tool assists in narrowing down a set of priority items. Additional steps in the priority-setting assessment can lead to a consensus being reached regarding the final outcome.
Efficient cluster-based routing protocol for wireless sensor networks by using collaborative-inspired Harris Hawk optimization and fuzzy logic
Authors: Hu Huangshui , Fan Xinji , Wang Chuhang
Published: April 2024

In wireless sensor networks, the implementation of clustering and routing protocols has been crucial in prolonging the network’s operational duration by conserving energy. However, the challenge persists in efficiently optimizing energy usage to maximize the network’s longevity. This paper presents CHHFO, a new protocol that combines a fuzzy logic system with the collaborative Harris Hawks optimization algorithm to enhance the lifetime of networks. The fuzzy logic system utilizes descriptors like remaining energy, distance from the base station, and the number of neighboring nodes to designate each cluster head and establish optimal clusters, thereby alleviating potential hot spots. Moreover, the Collaborative Harris Hawks Optimization algorithm employs an inventive coding mechanism to choose the optimal relay cluster head for data transmission. According to the results, the network throughput, HHOCFR is 8.76%, 11.73%, 8.64% higher than HHO-UCRA, IHHO-F, and EFCR. In addition, he energy consumption of HHOCFR is lower than HHO-UCRA, IHHO-F, and EFCR by 0.88%, 39.79%, 34.25%, respectively.
Approaching future rewards or waiting for them to arrive: Spatial representations of time and intertemporal choice
Authors: Fletcher Daniel , Houghton Robert , Spence Alexa
Published: April 2024

Our mental representation of the passage of time is structured by concepts of spatial motion, including an ego-moving perspective in which the self is perceived as approaching future events and a time-moving perspective in which future events are perceived as approaching the self. While previous research has found that processing spatial information in one’s environment can preferentially activate either an ego-moving or time-moving temporal perspective, potential downstream impacts on everyday decision-making have received less empirical attention. Based on the idea people may feel closer to positive events they see themselves as actively approaching rather than passively waiting for, in this pre-registered study we tested the hypothesis that spatial primes corresponding to an ego-moving (vs. time-moving) perspective would attenuate temporal discounting by making future rewards feel more proximal. 599 participants were randomly assigned to one of three spatial prime conditions (ego-moving, time-moving, control) resembling map-based tasks people may engage with on digital devices, before completing measures of temporal perspective, perceived wait time, perceived control over time, and temporal discounting. Partly consistent with previous research, the results indicated that the time-moving prime successfully activated the intended temporal perspective–though the ego-moving prime did not. Contrary to our primary hypotheses, the spatial primes had no effect on either perceived wait time or temporal discounting. Processing spatial information in a map-based task therefore appears to influence how people conceptualise the passage of time, but there was no evidence for downstream effects on intertemporal preferences. Additionally, exploratory analysis indicated that greater perceived control over time was associated with lower temporal discounting, mediated by a reduction in perceived wait time, suggesting a possible area for future research into individual differences and interventions in intertemporal decision-making.
Coupling coordination and underlying mechanisms of urbanization development and land use efficiency in the Gansu section of the Yellow River Basin
Authors: Lu Chenyu , Zhang Tong , Zhang Wendi
Published: April 2024

This swift progression of urbanization has led to increasingly prominent conflicts over the use of land, particularly around its supply and demand. Researchers, both in China and internationally, have underscored the inherent interconnection between urbanization and land utilization. This relationship has gradually become more complex with the development of urbanization. With the implementation of the Yellow River Basin’s strategy to preserve the environment while ensuring high-quality development, the Yellow River Basin has become a focal point of attention for numerous scholars. This study centers on the 57 county-level administrative divisions within the Gansu segment of the Yellow River Basin. We employed an extensive array of methodologies, such as GIS technology, the entropy method, data envelopment analysis, the coupling coordination degree model, and the panel vector autoregressive model. We established an index system and a measurement model to evaluate the degree of urbanization and the efficiency of land use. We also investigated the coupling coordinated dynamics between these two variables, to further explore the dynamic interplay between urbanization and land use and reveal their underlying mechanisms. The conclusions are as follows. The urbanization level and efficiency of land use in the Gansu section of the Yellow River Basin have exhibited a consistent upward trajectory, albeit at levels that are not particularly high, indicating substantial room for improvement in the future. The level of coupling coordination between urbanization and land use efficiency in the Gansu section of the Yellow River Basin has shown a generally upward trend. However, the overall coordination level remains relatively low, characterized by an imbalance, with “high coupling but low coordination”. Regarding spatial distribution patterns, considerable disparities exist in the level of coordination development, which generally decreases from the eastern toward the western regions. A strong reciprocal and interactive relationship exists between the urbanization level and land use efficiency. An elevated level of economic urbanization can initially stimulate land use efficiency. Similarly, the improvement in the level of population urbanization, social urbanization, and ecological urbanization tends to exert a restraining influence on the augmentation of land use efficiency. Conversely, the enhancement of land use efficiency makes a distinct contribution to promoting the elevation of the urbanization level.

Published: April 2024

Biliary atresia is a neonatal disease characterized by damage, inflammation, and fibrosis of the liver and bile ducts and by abnormal bile metabolism. It likely results from a prenatal environmental exposure that spares the mother and affects the fetus. Our aim was to develop a model of fetal injury by exposing pregnant mice to low-dose biliatresone, a plant toxin implicated in biliary atresia in livestock, and then to determine whether there was a hepatobiliary phenotype in their pups. Pregnant mice were treated orally with 15 mg/kg/d biliatresone for 2 days. Histology of the liver and bile ducts, serum bile acids, and liver immune cells of pups from treated mothers were analyzed at P5 and P21. Pups had no evidence of histological liver or bile duct injury or fibrosis at either timepoint. In addition, growth was normal. However, serum levels of glycocholic acid were elevated at P5, suggesting altered bile metabolism, and the serum bile acid profile became increasingly abnormal through P21, with enhanced glycine conjugation of bile acids. There was also immune cell activation observed in the liver at P21. These results suggest that prenatal exposure to low doses of an environmental toxin can cause subclinical disease including liver inflammation and aberrant bile metabolism even in the absence of histological changes. This finding suggests a wide potential spectrum of disease after fetal biliary injury.

Attitudes of the audience towards media messages on face mask use regarding the COVID-19 pandemic: From compliance to slacking
Authors: Epepe Umefien Dakoru , Okoro Nnanyelugo , Emmanuel Nathan Oguche , Gever Verlumun Celestine
Published: April 2024

The study focused on the transition from compliance to slacking in the audience’s attitudes towards media messages encouraging the use of face masks to avoid COVID-19. It employed the survey and multimodal analysis designs based on the Elaboration Likelihood Model (ELM). A sample of the messages on the Nigeria Centre for Disease Control (NCDC) website and YouTube were chosen for the multimodal analysis using purposive sampling. Findings showed that social media was one of the ways that most respondents commonly heard or saw messages about using face masks. Though short-term positive attitude and compliance were found, it mainly became inconsistent over time, despite the media blitz on the benefits of masking up. It recommended that there was an urgent need to re-contextualize media messages on using face masks by adopting a bottom-up strategy and a hybrid of communication approaches.
‘Can you hear me?’ ‘Son sur le scenario’: The act of writing sound in Mark Jenkin’s script of Enys Men (2022)
Authors: Marshall Kingsley
Published: April 2024

In 2000, Rick Altman, McGraw Jones and Sonia Tatroe presented the term mise en bande, or ‘putting onto the soundtrack’, as a framework to analyse the relationship between a film’s sound and its accompanying image. This article proposes an additional term for the study of sound on-screen – ‘son sur le scenario’ – the consideration of writing sound through the pages of a screenplay. Using the script of writer/director Mark Jenkin’s folk horror Enys Men (2023) as a case study, we consider cinematic sound through the perspective of its representation on the page, prior to its actualization through the subsequent processes of production, recording, design and postproduction. Under consideration is the manner that the written soundtrack can be used to articulate and evoke the complex temporal and spatial interrelationships with an imagined image at this stage of film development and its association with the visual realization of cinema’s characters, locations and narratives.

Authors: Borsatto Jaluza Maria Lima Silva , Pimenta Daiana Paula , Bazani Camila Lima , Jesuka Duterval
Published: April 2024

Objective: The purpose of this study is to analyze how the adoption of green innovation practices by companies can affect the economic (Gross Domestic Product - GDP), social (Human Development Index - HDI) and competitiveness (Global Competitiveness Index - GCI) Development of Developed Countries (DC) and Emerging Countries (EC).
Method: For the analysis, a three-level hierarchical regression model was used with repeated measures and estimated by Maximum Likelihood from a sample of 4061 publicly traded companies, 80% of which from the G7 countries and 20% from the BRICS (Brazil, Russia, India, China, and South Africa).
Results: The results showed that in relation to GDP, all green innovation indicators negatively influenced economic development in both DC and EC. With regard to the HDI, green innovation practices such as environmental management and environmental investments positively influence social development in DCs and ECs, respectively. As for competitiveness, the results revealed that only green innovation practices related to environmental policies showed statistically significant results demonstrating a negative relationship with the GCI both in the DC and in the EC.
Contributions: The study contributes with possible ways for companies and governments to set goals to achieve Sustainable Development Goals, SDG-8 to promote sustainable and inclusive economic growth, SDG-9 to promote inclusive and sustainable industrialization and foster innovation, and SDG-10 to strengthen and revitalize the global partnership for sustainable development.

P2X7 receptor: A receptor closely linked with sepsis-associated encephalopathy
Authors: Fan Zhao , Wang Kaifang , Zhao Xiaoyong , Sun Xude
Published: April 2024

Sepsis is defined as a dysregulated host response to infection resulting in life-threatening organ dysfunction. Sepsis-associated encephalopathy (SAE) is the main manifestation of sepsis. Inflammation, peroxidation stress injury, and apoptosis are the main factors involved in the pathogenesis of SAE. A growing body of evidence has proved that P2X7 receptor (P2X7R), a cationic channel receptor that is widely distributed in the body, plays a major role in the occurrence and development of inflammatory injury. Therefore, this review mainly describes the activation of P2X7R in sepsis, which leads to the recruitment of inflammatory cells to the cerebral vasculature, the destruction of the blood–brain barrier, the activation of microglial cells in the brain, the apoptosis of brain cells, and other damage processes. This review also illustrates the potential therapeutic value of P2X7R inhibition in SAE.
Injustice, Corruption, and Partisanship in the Eastern Seljuq Lands of the Early Twelfth Century: al-Ghazālī’s Persian Letters to Viziers as a Historical Source
Authors: Tor D. G.
Published: April 2024

This article analyses five historical missives written by the great theologian Abū Ḥāmid al-Ghazālī to three Seljuq viziers, and datable to the years 490/1097 to 504/1110 f. The first four of these letters form a progressive series complaining of governmental corruption in Ṭūs during the Seljuq civil war around the turn of the sixth/twelfth century, and thus provide the sole extant eyewitness testimony from Khurāsān during the last five years of the Seljuq civil war period. They also reveal al-Ghazālī’s vision of just rule far more concretely than do al-Ghazālī’s numerous theoretical writings on the subject. The fifth letter, written after the civil war had ended, explores the problem of intra-Sunni madhhab-based religious partisanship (taʿaṣṣub), and also incidentally reveals important biographical information about al-Ghazālī. All five of these letters constitute unique eyewitness testimony to some of the major political and social problems of the Seljuq period.

Published: April 2024

The classification of cuneiform signs according to stylistic criteria is a difficult task, which often leaves experts in the field disagree. This study introduces a new publicly available dataset of cuneiform signs classified according to style and Convolutional Neural Network (CNN) approaches to differentiate between cuneiform signs of the two main styles of the first millennium bce, Neo-Assyrian and Neo-Babylonian. The CNN model reaches an accuracy of 83 % in style classification. This tool has potential implications for the recognition of individual scribes and the dating of undated cuneiform tablets.

Authors: Barbier Eder , Nobre Carlos Eduardo Beserra , Iannuzzi Luciana , Bernard Enrico
Published: April 2024

Tonatia bidens is listed as ‘Data Deficient’ in the IUCN Red List. Our research, conducted in the Brazilian Caatinga dry forest between 2016 and 2022, aimed to shed light on the diet of this little-known species. Thirty-eight taxa were identified among insect remains beneath T. bidens’ feeding perch. Notably, certain insects such as hawkmoths and cerambycid beetles are agricultural pests with significant negative impacts on crops, including cassava, corn, tomato, papaya, and cashew plantations. These results underscore bats’ crucial role in insect pest consumption, emphasizing the need for further studies to fully understand their diet and ecosystem contributions.

Published: April 2024

Esophageal squamous cell carcinoma (ESCC), a highly aggressive subtype of esophageal cancer, is characterized by late-stage diagnosis and limited treatment options. Recent advancements in transcriptome sequencing technologies have illuminated the molecular intricacies of ESCC tumors, revealing metabolic reprogramming as a prominent feature. Specifically, the Warburg effect, marked by enhanced glycolysis, has emerged as a hallmark of cancer, offering potential therapeutic targets. In this study, we comprehensively analyzed bulk RNA-seq data from ESCC patients, uncovering elevated SRA1 expression in ESCC development and a poorer prognosis. Silencing of SRA1 led to a modulation of glycolysis-related products and a shift in PKM2 expression. Our findings shed light on the intricate molecular landscape of ESCC, highlighting SRA1 as a potential therapeutic target to disrupt glycolysis-dependent energy production. This metabolic reprogramming may hold the key to innovative treatment strategies for ESCC, ultimately improving patient outcomes.

The aim of this work was to evaluate the effect of 40 endophytic bacteria isolates on the control ofMeloidogyne javanicain ‘Prata-Anã’ banana seedlings. Two experiments were carried out in a completely randomized design with eight replicates. In each trial, 20 bacteria isolates and control were evaluated. Bacterial suspensions were applied to substrates during the acclimatization of seedlings at 15 and 30 days. On the 31st day, seedlings were transplanted into pots and soil was infested withM. javanicaegg suspension at 8 days. After 90 days, the following variables were evaluated: number of galls, egg masses, eggs per root, reproduction factor (RF), second-stage juveniles, and shoot dry matter. The results of nematological variables were submitted to Principal Components Analysis. In trial I, the variables that most contributed to data variability were as follows: number of eggs and RF. In trial II, RF had greater influence. Of the 40 isolates evaluated, 39 reduced RF, and of the 20 isolates evaluated in the first trial, all reduced the number of eggs per root.Bacillus methylotrophicusEB26,Bacillus cereusEB25, andBacillussp. EB37 isolates stood out in the control of nematodes, with RF reduction above 80%.
Solvothermal synthesis and selected properties of {[Ni(dien)2]3[V6As8O26]}2+·2 Cl– featuring the small [V6
IVAs8
IIIO26]4– cluster anion
Authors: Rasmussen Maren , Näther Christian , Bensch Wolfgang
Published: April 2024

A new arsenato-polyoxovanadate with the composition {[Ni(dien)2]3[V6As8O26]}2+·2 Cl– has been crystallized under solvothermal conditions as turquoise block-like crystals. The central structural feature is the [V6
IVAs8
IIIO26]4– cluster anion, which is composed of two trinuclear {V3O11} groups consisting of three edge-sharing VO5 polyhedra. Pairs of pyramidal AsO3 moieties share a common corner forming As2O5 units, which interconnect the {V3O11} groups. One of the [Ni(dien)2]2+ complexes adopts the s-fac (Ni1) and the second complex the mer configuration (Ni2). The Cl− anion is involved in strong hydrogen bonding interactions and links the [Ni(dien)2]2+ complexes to form twelve-membered rings which host the [V6As8O26]4– cluster anions. The Hirshfeld surface analysis yields a detailed picture of the intermolecular interactions revealing clear differences for the two unique [Ni(dien)2]2+ complexes. Intermolecular contacts also include As⋯H, O⋯H and H⋯H interactions. In the electronic spectrum the bands of d–d transitions of the vanadyl group and of the Ni2+ cations overlap, preventing a detailed analysis.
High-temperature all-solid-state batteries with LiBH4 as electrolyte – a case study exploring the performance of TiO2 nanorods, Li4Ti5O12 and graphite as active materials
Authors: Volck Marlena , Gadermaier Bernhard , Hennige Volker , Wilkening H. Martin R. , Hanzu Ilie
Published: April 2024

The hexagonal high-temperature form of LiBH4 is known as a fast ion conductor. Here, we investigated its suitability as a solid electrolyte in high-temperature all-solid-state cells when combined with the following active materials: Li metal, graphite, lithium titanium oxide (Li4Ti5O12, LTO), and nanocrystalline rutile (TiO2). First results using lithium anodes and rutile nanorods as cathode material show that a cell constructed by simple cold-pressing operates at reversible discharge capacities in the order of 125 mA h g−1 at a C-rate of C/5 and at temperatures as high as 393 K. Besides TiO2, the compatibility of the LiBH4 with other active materials such as graphite and LTO was tested. We found evidence of possible interface instabilities that manifest through rare, yet still detrimental, self-charge processes that may be relevant for hydrogen storage applications. Moreover, we investigated the long-term cycling behavior of the cells assembled and demonstrate the successful employment of LiBH4 as an easily processable model solid electrolyte in practical test cells.
Origin of extended visible light absorption in nitrogen-doped CuTa2O6 perovskites: the role of copper defects
Authors: Weiss Morten , Hofmann Anja , Marschall Roland
Published: April 2024

The optical band gap of the semiconductor CuTa2O6, synthesised via solid-state reaction, can be greatly reduced by annealing in ammonia, which leads to a significant red-shift of the visible light absorption. Using X-ray photoelectron spectroscopy (XPS), we have shown that this absorption extension does not result from the incorporation of nitrogen, but can be attributed to copper defects formed under the reducing conditions of ammonia treatment. Photocatalytic hydrogen evolution experiments were used to investigate the influence of these defects on the photocatalytic performance. We have further shown that CuTa2O6 with similar increased visible light absorption can be prepared by annealing with an organic reducing agent – sodium citrate – in inert gas atmosphere.

A new series of 4-nitroimidazole bearing aryl piperazines 7–16, tetrazole 17 and 1,3,4-thiadiazole 18 derivatives was synthesized. All derivatives were screened for their anticancer activity against eight diverse human cancer cell lines (Capan-1, HCT-116, LN229, NCI–H460, DND-41, HL-60, K562, and Z138). Compound 17 proved the most potent compound of the series inhibiting proliferation of most of the selected human cancer cell lines with IC50 values in the low micromolar range. In addition, compound 11 exhibited IC50 values ranging 8.60–64.0 μM against a selection of cancer cell lines. These findings suggest that derivative 17 can potentially be a new lead compound for further development of novel antiproliferative agents. Additionally, 17–18 were assessed for their antibacterial and antituberculosis activity. Derivatives 17 and 18 were the most potent compounds of this series against both Staphylococcus aureus strain Wichita and a methicillin resistant strain of S. aureus (MRSA), as well as against Mycobacterium tuberculosis strain mc26230. The antiviral activity of 7–18 was also evaluated against diverse viruses, but no activity was detected. The docking study of compound 17 with putative protein targets in acute myeloid leukemia had been studied. Furthermore, the molecular dynamics simulation of 17 and 18 had been investigated.

Published: April 2024

Indonesia's electoral democracy stands at a crossroads, balancing the foundational principles of Pancasila with global democratic norms and practices. This paper examines the dynamics shaping Indonesia's electoral democracy, exploring the tensions and harmonies between Pancasila's ideological framework and international democratic standards. The analysis begins by contextualizing the evolution of Indonesia's electoral democracy, tracing its roots in the post-authoritarian era and the subsequent institutional reforms. It then delves into the core principles of Pancasila, emphasizing its emphasis on collective welfare, social justice, and national unity. Drawing on comparative insights from global electoral democracies, the paper evaluates Indonesia's electoral system in light of international standards of electoral integrity, transparency, and inclusivity. It identifies areas of alignment and dissonance between Pancasila's ethos and global democratic benchmarks. Furthermore, the paper scrutinizes the role of Pancasila in shaping electoral processes, political parties, and voter behavior. It explores how Pancasila's emphasis on consensus-building and inclusivity intersects with the competitive nature of electoral politics. Through this analysis, the paper contributes to a nuanced understanding of Indonesia's electoral democracy, highlighting the complexities of navigating between Pancasila's indigenous values and global democratic imperatives. It underscores the importance of balancing national identity with international best practices to strengthen the legitimacy and effectiveness of Indonesia's democratic institutions.
Reproductive Ageing: Unlocking the secrets of reproductive longevity: the potential of social insects
Authors: Fernanda Vergara-Martínez María , Otero-Díaz Berenice , Fetter-Pruneda Ingrid
Published: April 2024

In brief

Social insect queens display both extraordinary longevity and fertility. In this point of view, we describe their distinctive traits that make them useful models for reproductive longevity, holding implications for human health discoveries.

Social insects present an extraordinary opportunity as models for reproductive longevity because they challenge the conventional patterns of aging and reproduction seen in other model organisms. Their queens are simultaneously long-lived and highly fecund, and understanding how these traits co-occur may lead to discoveries with important implications for human health.
Prone position in severe hypoxemia in patients with covid-19 during venovenous ECMO, does the number of cycles matter?
Authors: Mercado Díaz Mario Andrés
Published: April 2024

Extracorporeal membrane oxygenation (ECMO) support has been known to be beneficial in cases of severe Adult Respiratory Distress Syndrome (ARDS). The increase in such cases results in an increase in scenarios of severe hypoxemia even during an ECMO run. The purpose of this study was to evaluate the benefit of the prone position (PP) in an analytical observational retrospective cohort study. The study included adult patients with ARDS, caused as a result of SARS-CoV-2, undergoing PP during ECMO support in the period from 2020 to 2021. Thirty-five patients were placed in PP with an average of 3.6 cycles per patient. The group of patients undergoing >3 PP cycles had a significant improvement in oxygenation during PP, 𝑃𝑎𝑂2 (60.13 vs. 66.15, mmHg p = 0.0065) and 𝑃𝑎𝑂2⁄𝐹𝑖𝑂2 (136 vs. 155, p = 0.0026). After adjusting for confounding variables (age, RESP score, and days from the start of ECMO and the first cycle of PP), the group with >3 cycles showed a hazard ratio of 0.2 (95% confidence interval, 0.051–0.78; p = 0.02). The study outcomes confirmed the benefits of PP as a strategy against severe hypoxemia in ECMO, and evaluated variables such as the number of cycles, which may be associated with improved survival in this subgroup of critically ill patients.
Ball lightning and unidentified flying objects (UFOs)
Authors: I. Nikitin Anatoly
Published: April 2024

Descriptions of observations of large luminous objects (UFOs) are given. Particularly valuable is information about these objects obtained by pilots who saw them at close range. These objects are capable of flying at airplane speeds and emitting cone-shaped beams of light. Sometimes these rays break off before reaching the ground. When the beam hits a hard surface, it crumbles into “sparkles”. If there is close contact with a UFO, the aircraft's electronic equipment fails. Sometimes these objects “land” on the ground and take off, moving faster than the speed of sound. Objects remain invisible on the radar screen operating in the decimeter range. A hypothesis of the UFO device has been proposed. It is believed that UFO is an ensemble of ball lightning located in a common shell. The reason for the generation of cone beams of light is the synchrotron radiation of relativistic electrons that are part of the nuclei of ball lightning. Objects are capable of moving at supersonic speeds due to the emission of charged micro-clusters of water from their surface.

Ідентифіковано ризики за джерелами їх виникнення, визначено сутність ризиків аграрного й енергетичного ринків у контексті сучасних реалій. Узагальнено способи і методи управління ризиками, серед яких: ухвалення рішень на основі наявної інформації; отримання додаткової інформації; передача ризику; диверсифікація діяльності, лімітування; самострахування, резервування; страхування; хеджування. Охарактеризовано основні інструменти хеджування, визначено сутність і особливості деривативів, зазначено певні негативні сторони форвардних контрактів, переваги ф’ючерсних контрактів і опціонів. Обґрунтовано важливість використання інструментів хеджування в Україні. Запропоновано заходи для активізації функціонування деривативів на аграрному ринку в Україні, серед яких ключовими визначено: 1) проведення просвітницької діяльності для учасників аграрного ринку України з питань важливості використання фінансових інструментів для мінімізації цінових ризиків; 2) законодавче врегулювання; 3) організація майданчика для торгівлі деривативами і розширення можливостей їх використання як на національному ринку, так і шляхом простого і дешевого доступу учасників українського ринку до міжнародних ринків деривативів. Обґрунтовано доцільність єдиного торговельного майданчика в рамках спеціалізованого ринку України, що сприятиме забезпеченню ліквідності на ньому; 4) створення супутньої інфраструктури (сертифікованих складів, елеваторів; сучасних систем контролю якості й стандартизації продукції; каналів постачання, транспортної логістики; інфраструктури для швидкого обігу електронних складських свідоцтв); 5) організація ефективної фінансової інфраструктури для уможливлення торгівлі товарними деривативами в Україні; 6) ухвалення державної програми розвитку хеджування.

Реалізація системи заходів у агропромисловому комплексі й галузі енергетики, модернізація в рамках інших галузевих ринків в умовах війни здійснюються в міру можливостей, але ці кроки будуть надзвичайно важливими в системі повоєнного розвитку і реконструкції України.
Assessment of Multisensory Sensitivity May Assist With the Management of Children With Chronic Pain

Chronic pain is a significant problem in adults; however, it can also be challenging to evaluate and manage effectively in pediatric and adolescent populations. Many theories implicate different factors that cause pain to become chronic, more severe, or more detrimental to function. There is emerging evidence for the role of generalized multisensory sensitivity (MSS) as a contributing factor to chronic pain in the adult population; however, similar evidence in the pediatric literature is lacking. Thus, the purpose of this case series is to highlight the clinical use of MSS assessment in children and adolescents with chronic pain to better phenotype and provide targeted treatment. In this case series, we reviewed 5 patients between 12 and 16 years of age who received evaluation for multifocal, chronic pain in a multidisciplinary pain clinic. During the initial consultations, we reviewed the medical records, completed a full medical history, performed a physical examination, and assessed for MSS. It is theorized that MSS is a marker of increased central nervous system sensitivity to sensory input that may also impact pain processing and, potentially, a poorer prognosis. Four patients with MSS appeared to benefit from the inclusion of additional therapies, such as desensitization and occupational therapy, which was in contrast to the patient without notable MSS. Based on anecdotal observation of these 5 cases, increased sensory hypersensitivity is 1 additional factor that may be used to delineate possible neurobiological mechanisms and aid in the treatment decision-making for this challenging population.

Published: April 2024

Las formas de comunicarse entre las audiencias y las marcas en el entorno digital ha llevado al desarrollo de la “web social” donde los internautas participan activamente en los procesos de comunicación, tales como producción y recepción de una diversidad de archivos. Dentro de un gran espectro de plataformas dedicadas a esto, existe la red social Tik Tok donde colindan las comunidades virtuales y publicidad. Esta investigación explora la situación comunicacional de la publicidad de las marcas Pepsi y Bilz y Pap en Chile dentro de la red social Tik Tok con el objetivo de formular una guía de ayuda para aportar al desarrollo de marcas nuevas y el emprendimiento dinámico en el territorio nacional, y especialmente en la región de Coquimbo, para que de esta manera las pymes puedan conocer y actualizar su estrategia comunicacional y lograr el alcance, ventas y visibilidad esperada. En este sentido, se recurrió a un diseño no experimental que se aplicó de manera transversal, utilizando el método de “estudio de caso” de las marcas ya mencionadas durante los meses febrero - mayo 2021, como una ventana que permita un acercamiento exploratorio al fenómeno que supone la aparición de Tik Tok y los influencers como componentes recientes en la comunicación publicitaria. Adicionalmente, la investigación se desarrolló de acuerdo al planteamiento metodológico del enfoque mixto, se trató de utilizar un método elaborado acorde a las necesidades del estudio incluyendo el análisis de datos tanto de naturaleza cuantitativa como cualitativa, donde se comprobó que Tik Tok sí es un medio viable para comunicar efectivamente y lograr un alcance e influencia significativa, convirtiéndose en una herramienta útil y asequible para pequeños y medianos emprendimientos dinámicos locales.

Bedbug (Cimex lectularius) infestations in Colombia. Report of two cases
Authors: Porras-Villamil Julián Felipe , Olivera Mario Javier
Published: April 2024

Abstract
Introduction: Cimex lectularius (bed bug) is a hematophagous parasite that can be considered as an emergent and neglected concern in Colombia. Due to their increasing importance, the following two clinical cases secondary to a bed bug infestation are presented.
Case presentation: Two patients, one male and one female (31 and 30 years old, respectively) went on their honeymoon trip to Costa Rica and Nicaragua in 2017. During those trips, both patients stayed in the same room in hotels of different categories. Upon their return to Bogotá (Colombia), erythematous lesions and pruritic papules appeared without any apparent explanation, which were associated with intense pruritus and had a clustered and linear (breakfast-lunch-dinner) pattern. During consultation with the Travel Medicine service, a diagnosis of dermatitis due to bed bug infestation was made. With the recommendations given by the medical staff (in which no chemical measures were suggested), the bugs and lesions disappeared.
Conclusion: Bed bugs are a public health problem of increasing importance worldwide. This report of two cases presents one of the few published evidences of their presence in Colombia. As both cases are domestic, the relevance of an early diagnosis and a comprehensive approach based on the needs of the patients is demonstrated.

Objective To establish the purchase price, authorization strategies, availability of health registrations and technical specifications for the purchase of mechanical ventilators in Latin America during the COVID-19 pandemic.
Methods A health technology assessment was conducted by searching for technical specifications, health registrations and safety information on mechanical ventilators purchased by nine Latin-American countries including Colombia, Guatemala, Mexico, Argentina, Uruguay, Costa Rica, Brazil, Paraguay, and Peru. Based on the information of 129 tenders and contracts, technical information was obtained from the websites of 32 suppliers and manufacturers, covering 55 different models of mechanical ventilators. This information was compared to the World Health Organization’s technical specifications for mechanical ventilators. Information on the availability of health registrations and safety of ventilators was obtained from searching the websites of the sanitary agencies of the nine countries. Information was recorded in a form designed by the researchers.
Results In the purchase of mechanical ventilators, significant differences were found in prices, depending on the date of acquisition. Several devices were identified as being non-compliant with some of the technical criteria established by the World Health Organization.
Conclusions Access to information on contracts for the purchase of mechanical ven- tilators is limited, both in terms of access and public consultation. Complete technical information must be required from manufacturers and suppliers and information gaps should be avoided, especially for public purchasing processes.
