Rocuronium vs Succinylcholine: Emergency Airway Management of the COVID-19 Patient
Authors: Shores Ryan , Fowler Katherine , McDonough John , Suralis Amy , Scindele Denise , Müller-Wolff Tilman
Published: August 2024

Tracheal Intubation is routinely performed in many settings.  Anesthesia providers are experts in this procedure.  Determination for the best possible approach for tracheal intubation include patient and provider specific considerations.  Severe acute respiratory syndrome-coronavirus-2 (SARS CoV-2) infection has led to the COVID-19 pandemic.  SARS CoV-2 is a highly contagious RNA virus that has caused widespread infections, severe respiratory disease, and deaths.  The purpose of this article is to describe the airway management currently recommended in Germany as well as the United States, the multi-systems pathophysiologic complications of these patients, and review the need for minimum airway manipulation prior to intubation of the trachea.  Further, this article discusses the pharmacologic options that are available for muscle relaxation during rapid sequence induction.  A review of the literature was performed.  Further, some authors of this article have actively participated in airway management of COVID-19 patients.  Available literature and guidelines suggest that rapid sequence induction with minimal airway manipulation is superior to standard induction. The article suggests that appropriate doses of rocuronium with an option of sugammadex reversal is a safer and superior choice to succinylcholine.

Published: August 2024

Monografia Zofia Rydet po latach. 1978–2018 to niewątpliwie publikacja naukowa najwyższej próby. Na jej wyjątkową wartość naukową nie tyle ma wpływ poprawność warsztatowa, jasność i logika wywodu, a nawet temat, który dotychczas nie doczekał się wyczerpującego omówienia w literaturze przedmiotu, co przede wszystkim prezentacja nowych, a ściśle rzecz ujmując, z tej okazji specjalnie pozyskanych źródeł, które niewątpliwie spełnią rolę materiału badawczego dla refleksji współczesnej humanistyki. Należy podkreślić, że owe źródła nie dotyczą wyłącznie samej Zofii Rydet, ale w niemałym stopniu odkrywają problematykę artystyczną i cechy kilku dekad twórczej działalności artystów fotomedialnego nurtu sztuki, co z natury rzeczy stanowi źródło wiedzy nie tylko o bohaterce opracowania, ale również kreśli panoramę polskiej fotografii i jej społecznych uwikłań w latach 1978–2018.

Published: August 2024

Background: The aim of this experiment was to investigate the differences in subcutaneous fat metabolism expression in yaks under natural grazing and housed feeding conditions in the cold season. Eighteen 18-month-old yaks with similar body weights and non-significant differences in dorsal subcutaneous fat were randomly divided into three groups. Methods: One group (G18_SF) of yaks was selected for slaughter at the beginning of the experiment (October), one group continued to graze for 6 months and then slaughtered (G24_SF) and one group was housed for 6 months and then slaughtered (F24_SF) and subcutaneous dorsal fat of the three groups was collected for metabolomic analysis, screening of differential metabolites and enrichment of KEGG pathway. Result: In this experiment, 110 differential metabolites were detected in G24_SF vs F24_SF and 83 metabolites were screened for down-regulation and 27 metabolites were up-regulated and the differential metabolites were mainly enriched in Alanine, aspartate and glutamate metabolism, Arachidonic acid metabolism and D-Glutamine and D-glutamate metabolism pathways. Ninety-seven differential metabolites were detected in G18_SF vs G24_SF and 41 metabolites were screened for down-regulation and 56 metabolites were screened for up-regulation, with the two groups of differential metabolites mainly enriched in Alanine, aspartate and glutamate metabolism, Caffeine metabolism and Starch and sucrose metabolism pathways. The results of this experiment revealed the information of differential metabolites and enrichment pathways of yak fat in different feeding methods and different months of age and laid the foundation for further in-depth study of subcutaneous fat deposition in yaks.

Authors: Teles Ricardo , Yamana Mateus Ryrochi Borges
Published: August 2024

The present research aimed to develop products for the musical instruments market using wood modified through heat treatments. Initially, a survey of wood traditionally used in musical instruments, or their parts was carried out. Subsequently, bibliographic research about the wood modification treatments was produced to know the technical limits and their characteristics and to identify which of these can be applied in Brazilian woods, being then chosen as the technique of heat treatment with the application of temperatures of 160ºC and 200ºC carried out in laboratory ovens. From this, the musical instrument xylophone was chosen as a test product to evaluate the use of the chosen technique of modification for the roxinho wood (Peltogyne sp.). Thus, the musical instrument was designed and produced with untreated wood and treated with the mentioned temperatures and evaluated the mass loss, specific gravity, resonance frequency, sound propagation velocity and dynamic modulus of elasticity (MOEd). The results indicated that the treatment with the temperatures used increased the sound propagation velocity and the MOEd, even with the decrease in the apparent density. The production of the product also showed a significant gain in relation to the final timbre when compared to untreated wood. Thus, the use of temperature at 160ºC is indicated as a technological product that can increase the final quality of the musical instrument.

From NAFLD to MAFLD and MASLD: a tale of alcohol, stigma and metabolic dysfunction
Authors: Ciardullo Stefano , Perseghin Gianluca
Published: August 2024

Liver steatosis is a frequent finding in clinical practice and it is estimated to affect 30% of the general adult population worldwide. It became one of the leading causes of end-stage liver disease and hepatocellular carcinoma. From its first description, a diagnosis of nonalcoholic fatty liver disease (NAFLD) required the exclusion of excessive alcohol consumption and concomitant chronic liver diseases of different origins, making it a diagnosis of exclusion. In recent years, the need to stress the strict association between liver steatosis and metabolic dysfunction (i.e., insulin resistance, overweight/obesity, type 2 diabetes, and metabolic syndrome), as well as the desire to define a condition in a positive rather than negative way, led to new definitions and new diagnostic criteria. Metabolic dysfunction-associated fatty liver disease (MAFLD) was proposed by Eslam et al. in 2020. More recently, a Delphi consensus endorsed by several international hepatologic societies proposed a new terminology [metabolic dysfunction-associated steatotic liver disease (MASLD)] and a new set of diagnostic criteria. The MAFLD and MASLD definitions have a good degree of concordance. They mainly differ in the number of metabolic derangements needed to define “metabolic dysfunction” in normal-weight individuals and in alcohol consumption. Indeed, while MAFLD does not exclude patients with significant alcohol consumption, the recent Delphi consensus included the metabolic dysfunction and alcohol-related liver disease (MetALD) disease entity, a condition in which steatosis, metabolic dysfunction, and moderate alcohol intake coexist. In the present narrative review, we underline the strengths and possible limitations of each definition and summarize available evidence from epidemiologic studies evaluating the clinical usefulness of each set of diagnostic criteria.

Published: August 2024

Випаровування –  це процес фазового переходу, який відіграє важливу роль у багатьох сферах життя і науки. Випаровування небезпечних матеріалів, пестицидів, розливів нафти тощо впливають на навколишнє середовище та біосферу. Прогнозування потоків випаровування в конкретних умовах навколишнього середовища є складним завданням з теоретичної та емпіричної точок зору. На основі наших експериментальних результатів і раніше опублікованих даних запропоновано новий практичний метод оцінювання потоків. Продемонстровано, що деякі параметри в теоретичних рівняннях для майже рівноважного випаровування можна оцінити з експериментів, і ці формули можуть бути використані для прогнозування стаціонарних потоків випаровування в повітрі в діапазоні величини восьми порядків на основі одного проведеного експерименту для нетоксичних летких сполук.

З кожним роком антропогенний вплив на навколишнє середовище, а особливо на атмосферу, зростає. Це веде до погіршення умов існування людини і живих організмів і, в кінцевому результаті, може призвести до глобальної екологічної кризи. В України за рівнем забруднення м. Київ займає одне з перших місць. З метаю покращення якості повітря необхідно володіти детальною інформацією про рівень забруднення, забруднювачі, джерела їх утворення, зміни в часі та просторі і т. і. В більшості розвинутих країн світу ці функції виконують національні системи моніторингу забруднення довкілля, котрі відкриті, автоматизовані, комп’ютеризовані та відображають інформацію в реальному часі. Сьогодні національна система моніторингу довкілля в Україні лише починає формуватися, тому важливо визначити найбільш прийнятні напрямки її розвитку.
Сьогодні моніторинг якості повітря в столиці проводиться кількома суб’єктами. Протягом тривалого часу цими питаннями опікується Центральна геофізична обсерваторія. Сьогодні обсерваторія володіє найбільш детальною інформацією щодо якості повітря в столиці протягом тривалого періоду. Останні кілька років характеризуються інтенсивним розвитком недержавних систем моніторингу якості повітря в столиці. Більшість таких систем моніторингу носять, швидше, рекламний характер для окремих суб’єктів господарювання або розраховані на створення мережі спостережних постів за кошти самих громадян. Кілька років тому КМДА було прийнято рішення про створення сучасної відкритої автоматизованої системи моніторингу якості повітря в столиці. На сьогодні встановлено та запущено в роботу чотири спостережних пункти.
Система моніторингу якості повітря в столиці найімовірніше, розвиватиметься саме шляхом встановлення нових сучасних постів спостереження в межах міста в об’ємі програми КМДА.

Дельта Дунаю – це динамічна і складна гідроекосистема, що відноситься до найбільших перехідних екотонів типу «річка-море». Такі водні об’єкти особливо вразливі до змін і викликів навколишнього середовища, окрім того перебувають під постійним антропогенним навантаженням. Моніторинг і дослідження біорізноманіття гідробіонтів та їх характеристик є необхідним для нормального функціонування і життєдіяльності біоценозу.
Так, дослідження фітопланктону різнотипних водних об’єктів пониззя Дунаю встановило, що видове різноманіття представлено нерівномірно: у великих придунайських озерах 188 видів (191 в.в.т.); у різнотипних водоймах і водотоках пониззя Дунаю (рукава та затоки) 156 видів (158 в. в. т.); а у гідроекосистемі р. Дунай – канал Дунай-Сасик – Сасицьке водосховище 87 в.в.т.
У роботі використаний метод біоіндикації, а саме метод індикаторних організмів сапробності. Аналізуючи індивідуальні показники сапробності фітопланктону, встановлено, що найбільше представників - β-мезосапробної зони, що в свою чергу відповідає III класу якості води , які охарактеризовані як «помірно забруднені».

Authors: Spinarelli Antonio , Moretti Biagio , Catalano Maria , Smaldino Marco , Solarino Giuseppe
Published: August 2024

Periprosthetic joint infection (PJI) is one of the major complications resulting from the implantation of a joint prosthesis. Staphylococci are responsible for more than 50% of prosthetic infections, about 20% can be polymicrobial, 15% are gram-negative and about 10% of cultures are negative. The complete eradication of the infection is extremely difficult. For a correct treatment is first of all useful to perform a clinical staging based on the anatomical location of the infection and on the immune characteristics of the host. However, regardless the area of infection, the role of the surgeon is crucial, firstly in terms of timing and secondly in assessing the degree of invasiveness of the infected and necrotic tissues required. The goal of the treatment must be to eradicate the infection ensuring the maximum functional result.

Published: August 2024

The comfort of the elderly in hospital settings requires a special attention from the involved health care professionals, particularly nurses, since hospitalization often generates suffering and discomfort. In such contexts, it is essential to take into account the specific characteristics of the elderly, considering their life experiences and their needs, to promote the health, well-being, and comfort of this population. Hence, the present work aimed to explore the nursing interventions that promote comfort among the elderly in hospital settings. A mixed descriptive exploratory study was conducted, through the application of a questionnaire, using intentional non-probabilistic sampling. The study encompassed 55 elderly individuals hospitalized in a medical service of a public hospital located in Lisbon. The results show that the participants perceived a reasonable level of comfort (5.65 ± 6.46). The following categories emerged from the content analysis: 1) Physical interventions; 2) Psycho-spiritual interventions; 3) Socio-cultural interventions; and 4) Environmental interventions. These findings help to understand comfort-promoting nursing interventions in the studied population. It was concluded that, to improve care quality, comforting interventions should focus on the elderly patient’s individuality, through support activities, empowerment, and the preservation/correction of the surrounding environment. Additionally, the provided care should be based on the real needs, expectations, preferences, and values of the elderly individual.

Published: August 2024

The energy transition towards Net Zero Emission by 2060 hinges on the renewable energy power plants in Indonesia. Good practices in several countries suggest a peer-to-peer (P2P) energy trading system using blockchain technology, supported by renewable energy (solar panels), an innovation to provide equal access to sustainable electricity while reducing the impact of climate change. The P2P energy trading concept has a higher social potential than the conventional electricity buying and selling approach, such as that of PLN (the grid management concept), but does not have a sharing element. This model implements a solar-powered mini-grid system and produces a Smart Contract that facilitates electricity network users to buy, sell, and trade electricity in rural areas via smartphones. This study aims to analyze the stakeholders' perceptions of the peer-to-peer (P2P) energy trading model using blockchain technology in Gumelar District, Banyumas Regency, Central Java Province, Indonesia. The stakeholders include households, the Ministry of Energy and Mineral Resources (ESDM), the State Electricity Company (PLN), the Institute for Essential Services Reform (IESR), Awina Company, and IPB University. The strength factors of this model are the freedom to generate and sell electricity (0.1) and transparency in electricity usage and sales by disclosing the amount, duration, and price of electricity (0.1). Regarding weakness factors, this model is primarily suitable for the lower middle class residing in rural or remote areas (0.02). Additionally, the intermittent electricity production to meet the substantial demand is a weakness (0.03). The opportunity factor for the model is the increase in public awareness and cooperation in using environmentally friendly, pollution-free electricity (0.12). Furthermore, there is an opportunity for additional income (0.12) and new business investment (0.12). Regarding threat factors, the model faces significant threats from the implementation aspect involving multiple parties (0.04). There is a potential threat in the form of losses for state utilities such as PLN or individuals who have already established electricity infrastructure if this program is implemented on a large scale (0.04). This model is located at the coordinate point (-0.40; 0.31), placing it in quadrant II. This indicates that the model should apply the Stability Strategy and focus on the Selective Maintenance Strategy for improvement. The stability strategy goal is to maintain the current situation by leveraging opportunities and addressing weaknesses. For effectiveness and efficiency, the strategy emphasizes fostering collaboration with PLN, which holds the legal authority as the sole utility company in Indonesia with an extensive electricity network, as well as advocating for regulations that support the independent purchase and sale of solar-powered electricity, particularly in areas without PLN network coverage.

Rotator cuff (RC) repair leads to less than optimal results when dealing with massive lesions, so the use of scaffolds as biological support has been proposed to improve RC repair site biology. The present study aims to evaluate the clinical and radiographical outcomes in a series of patients suffering from massive or irreparable RC tears treated with patch (porcine or human scaffolds) repair (augmentation or bridging). Twenty-three patients with a minimum follow up of 24 months were subjectively with 3 patient-related outcome measurements (PROMs) (American Shoulder and Elbow Surgeons score, Constant score, visual analog scale), clinically and radiographically assessed before and after surgery. Regardless the technique (augmentation or bridging) or type of scaffold (porcine or human) employed, at follow up all patients experienced a statistically signif-icant improvement in all PROMs, and clinically. Patch repair represents a valid salvage procedure in massive or irreparable RC tears improving the quality of life and eventually delaying the need for prosthetic replacement.

(1) Background: Allergic reactions and angioedema are important immunologic conditions in acute care settings. Prior data indicate an association between the severity of symptoms and maximum lysis (ML) in thromboelastography. We aimed to evaluate the dynamics of ML after two hours of observation after admission to the emergency department. (2) Methods: We deter-mined ML with thromboelastography using extrinsic testing (EXTEM, ROTEM®, Werfen GmbH, Munich, Germany) at the presentation of patients with immunologic reactions and approximately two hours thereafter. The median test was used to compare the extent of ML between individuals who were still symptomatic at follow-up and those who were asymptomatic. (3) Results: We pro-spectively enrolled 16 individuals (10 (63%) female, mean age 50±14 years). Of these, 6 (38%) were still symptomatic at follow-up. Patients who had persistent symptoms had significantly higher ML than those who were asymptomatic (14% (IQR 12-17) vs. 8% (IQR 4-10), p=0.002). (4) Conclusions: ML is elevated in patients who are still symptomatic two hours after presenting to the emergency department due to an immunologic reaction.

The synthesis of enantiomeric forms of D-amino acids can be achieved by a two-step "hydantoinase process" based on the sequential catalysis of substrates by specific enzymes, D-carbamoylase and D-hydantoinase. In addition to our previously studied D-hydantoinase, we describe here the structural features of D-carbamoylase from Pseudomonas, the encoded gene of which was chemically synthesized and cloned into Escherichia coli. A significant fraction of the overexpressed recombinant protein forms insoluble inclusion bodies, which are partially converted to a soluble state upon treatment with N-lauroylsarcosine or upon incubation of the cells at low temperatures. Analysis of the substrate specificity of the purified His-tag protein showed that D-carbamoylase exhibits the highest activity toward N-carbamoyl-D-alanine and N-carbamoyl-D-tryptophan. Molecular docking analysis revealed the location of the substrate binding site in the three-dimensional structure of D-carbamoylase. Molecular dynamics simulations showed that the binding pocket of the enzyme in complex with N-carbamoyl-D-tryptophan is stabilized within 100 ns. The free energy of binding indicated a possible role of residues Arg176 and Asn173 in the formation of hydrogen bonds between the enzyme and N-carbamoyl-D-tryptophan. The properties of the studied D-carbamoylase and D-hydantoinase support further development of a combined biotechnological process for the production of new drugs and peptide hormones.

Published: August 2024

In this contribution, the propylamine-functionalized cellulose (Cell-Pr-NH2) was employed as the catalyst in the three-component reaction between hydroxylamine hydrochloride, various type of aryl/heteroaryl aldehydes, ethyl acetoacetate/ethyl 4-chloroacetoacetate/ or ethyl 3-oxohexanoate. The results of these experiments were the formation of 3,4-disubstituted isoxazol-5(4H)-one heterocycles. The desired five-membered heterocyclic compounds were obtained in good to high yields at room temperature. The investigation of different solvents led us to the conclusion that water is the best solvent to perform the current one-pot, three-component reactions. Attempts to find the optimum catalyst loading clearly showed that 14 mg of Cell-Pr-NH2 seems to be sufficient to carry out the reactions. This method has highlighted some principles of green chemistry including less waste generation, atom economy, use of water as an environmentally friendly solvent, and energy saving. Purification without chromatographic methods, mild reaction conditions, simple work-up, low-cost reaction medium, saving time, and obtainable precursors are other notable features of this one-pot fashion.
An Assessing the Role of Watershed Management Practices in Gullele Botanical Garden, Addis Ababa, Ethiopia
Authors: Diribsa Gudeta
Published: August 2024

AbstractEthiopia is a country that is in the process of development. Unfortunately, the management and utilization of watershed resources in this region are inadequate. This has resulted in a decrease in the quality of essential resources like soil, water, plants, and animals. Our research delved into the intricate biophysical conditions, conservation practices, and key issues surrounding watersheds along with their root causes and current strategies. The study was particularly focused on understanding the reality and different approaches employed in watershed management practices at the Gullele Botanical Garden located in Addis Ababa. We gathered information through interviews with experts and technicians, direct on-site observations, and official records from the garden's administration office. The gathered data was meticulously analyzed both qualitatively and quantitatively using Arc Map 10.3 to gain a comprehensive understanding of the area. Our findings revealed that the main objective of watershed management in areas surrounding restricted forest sites, Dam A, and Dam B was centered on conserving soil and water resources. The study emphasized the importance of selecting appropriate technologies for effective water and soil conservation practices. Data collection was done using purposive and random sampling methods, drawing information from a variety of sources such as the Gullele Botanical Garden office, literature, research reports, student theses, and both published and unpublished organizational documents. Despite these efforts, our study highlighted inefficiencies in the institutions responsible for watershed management. In particular, the maintenance of stone bunds, gullies, and gabions was not conducted adequately, leading to project deficits. Moving forward, we recommend raising awareness, enhancing training programs, and strengthening law enforcement and watershed policies to transform the knowledge, skills, and attitudes of technicians and staff involved in watershed management techniques for the better.

Published: August 2024

To achieve real-time identification of soybean seedlings and weeds in soybean seedling fields on agricultural intelligent terminal devices, this article constructs a real-time evolutionary identification system ESWIM driven by computational complexity under few-shot training. Firstly, based on the identification task, high-quality image samples are collected and annotated. By analyzing the terrain, the weather during the growth period, image acquisition methods, and the status of equipment fieldwork, we obtained a suitable enhancement algorithm. This algorithm not only effectively simulates the diversity of actual images, but also solves the problem of significant imbalance in the number of targets. Then, using the computational complexity driven approach and YOLOv5n as the foundation model, a soybean seedling and weed recognition model SWIM is constructed. The model's computational space and time complexity are reduced by 45.19% and 42.86%, respectively, while mAP (0.5) increased by 0.1%. Finally, by utilizing human-computer interaction to enable real-time and effective evolution of the dataset, an evolutionary strategy is designed to rapidly iterate and update model parameters, resulting in the development of the evolutionary system ESWIM. Laboratory experiments have shown that the ESWIM system can quickly adjust the recognition system during device operation to achieve target identification tasks in different environments.

Published: August 2024

Background: Inflammatory Bowel disease (IBD) is one of the worldwide health issues with increasing incidence. Recent data point out that those patients can have a defective immune system, rendering response to vaccinations suboptimal. Since 1990, Hepatitis B Virus (HBV) vaccination has been introduced among the compulsory childhood vaccinations in Oman. Given the questionable immunogenicity of vaccinations in IBD patients, we designed this study to quantify the immune response to scheduled HBV vaccine in IBD patients and compare it with that in a matching control cohort of healthy blood donors at Sultan Qaboos University Hospital (SQUH). Methods: This is a retrospective case-control study that was conducted between the 1st of July 2023 and the 31st of May 2024 at SQUH. Using the hospital information System (HIS), a total of 252 participants were enrolled in our study and divided into two groups. Group (1) included 126 IBD patients and group (2) included 126 healthy controls. Baseline demographics, medical comorbidities and viral serologies before and after vaccination were collected. The primary outcome of the study was to compare the long term immune response to HBV vaccine between the two groups. The secondary outcomes included identifying possible risk factors for suboptimal vaccine response. Results: One hundred and twenty-six participants were included in each group. Durable protective immune response to HBV vaccine was attained in 29 patients (23%) of the IBD group compared to 109 participants (86.5%) of the control group. There was a statistically significant association (p = 0.0156) between prednisolone treatment and low immune response to HBV vaccine. Moreover, esomeprazole usage exhibited a statistically significant association (p < 0.0001) with suboptimal response to HBV vaccine. Meanwhile, there was no statistically significant correlation between low immunogenicity to HBV vaccine and age, sex, type of IBD, comorbidities, and BMI. Conclusions: IBD patients are less immunogenic to HBV vaccination compared to healthy controls. Factors like esomeprazole and/or corticosteroid therapy might be associated with poor immune response. These findings highlight the importance of reassessing the immunogenicity of HBV vaccination and probably other protective vaccinations in all IBD patients as part of their standard of care.
