Authors: Jose Meenu , Prakash Ardra , Gupta Neetu , Subhash Swathy , Shijukumar C , Joji Prameela
Published: January 2023

Background:

Sedation management is a crucial element of pediatric critical care medicine, aiming at reducing children's anxiety, distress, and oxygen demand. Prolonged administration of sedatives may result in drug tolerance and physical dependency. Abrupt discontinuation of these drugs in children may cause withdrawal symptoms. Our study aims to evaluate the choice and adequacy of sedation in ventilated children using the University of Michigan Sedation Scale score.

Subjects and Methods:

All the children aged between 1 and 12 years who were subjected to invasive ventilation during the time period October 2019 to June 2021 in the tertiary care pediatric intensive care unit (PICU) were included in the study.

Results:

Of the 35 children enrolled in the study, most of them spend the majority of their time in adequate sedation which accounts for around 87.1% of the total time of ventilation. Fentanyl and midazolam were the most frequently used drug combination. Oversedation and undersedation accounted for 7.9% and 5% of total ventilation hours, respectively. Out of 35 children, 10 (28%) developed iatrogenic withdrawal symptoms and 4 (11%) developed severe withdrawal symptoms.

Conclusions:

Fentanyl and midazolam were the most frequently used drug combination for attaining adequate sedation in our PICU. Irrespective of adequate sedation, no increase in the incidence of iatrogenic withdrawal syndrome, undersedation, or oversedation was noted in our study population.

Published: January 2023

Inherited ocular diseases comprise a heterogeneous group of rare and complex diseases, including inherited retinal diseases (IRDs) and inherited optic neuropathies. Recent success in adeno-associated virus-based gene therapy, voretigene neparvovec (Luxturna®) for RPE65-related IRDs, has heralded rapid evolution in gene therapy platform technologies and strategies, from gene augmentation to RNA editing, as well as gene agnostic approaches such as optogenetics. This review discusses the fundamentals underlying the mode of inheritance, natural history studies and clinical trial outcomes, as well as current and emerging therapies covering gene therapy strategies, cell-based therapies and bionic vision.

Published: January 2023

Purpose We investigated the clinical effects and predictive factors of severe post-chemoradiotherapy pulmonary complications (PCPC) in locally advanced non–small cell lung cancer (LA-NSCLC).Materials and Methods Medical records of 317 patients who underwent definitive concurrent chemoradiation (CCRT) for LA-NSCLC were reviewed retrospectively. PCPC was defined as an event of admission or emergency department visit for acute or subacute pulmonary inflammatory complications, including pneumonitis and pneumonia, within 6 months after CCRT initiation. Patient characteristics, baseline lung function tests, radiation dosimetric parameters, and laboratory tests were analyzed to investigate their association with PCPC. Prognostic endpoints were disease progression rate (DPR) and overall survival (OS).Results PCPC was reported in 53 patients (16.7%). The OS of patients with PCPC was significantly worse (35.0% in 2 years) than that of patients without PCPC (67.0% in 2 years, p < 0.001). However, 2-year DPRs were 77.0% and 70.7% in patients with and without PCPC, respectively, which were not significantly different (p=0.087). In multivariate logistic regression, PCPC was independently associated with grade ≥ 1 hypoalbuminemia during CCRT (odds ratio [OR], 5.670; 95% confidence interval [CI], 2.487 to 13.40; p < 0.001), lower diffusing capacity of carbon monoxide (DLCO) (per mL/min/mmHg; OR, 0.855; 95% CI, 0.743 to 0.974; p=0.022), and higher lung V5 (per 10%; OR, 1.872; 95% CI, 1.336 to 2.699; p < 0.001).Conclusion PCPC might be a clinical endpoint to evaluate complications and predict the survival of patients subjected to CCRT for LA-NSCLC. Hypoalbuminaemia, DLCO, and lung V5 might predict PCPC in LA-NSCLC.

Authors: Amoah John , Said Salmiah Md. , Rampal Lekhraj
Published: January 2023

BACKGROUNDGlobally, the harmful use of alcohol is the cause of 3 million (5.3%) deaths. The prevalence of alcohol use among students has been increasing and there is, therefore, the need to explore the situation and solutions to tackle it. The study sought to determine the prevalence and predictors of alcohol use among public secondary school students.METHODOLOGYA cross-sectional study was carried out among 848 students from two districts in Ghana who completed a set of questionnaires on alcohol use. Chi-square tests were carried out to determine associations between demographic characteristics and alcohol usage; and gender and age of onset of alcohol use. Binary logistic regression was performed to determine predictors of alcohol use.RESULTSOf the 848 study participants, 437 (51.5%) were females. The prevalence of alcohol use was 22.2%. The mean (SD) age of first alcohol use was 13 (2.1) years. Predictors of alcohol use were male gender 3.561 (p=0.003), friends 4.435 (p<0.001) and parents’ 5.302 (p<0.001) use of alcohol.CONCLUSIONThe prevalence of alcohol use among students in this study was high, with many students consuming alcohol at an early age. There is a need for effective health education interventions targeted at secondary school students to reduce alcohol use.

Historia medycyny w sześciu niepełnych odsłonach jest propozycją spojrzenia na dzieje nauki i sztuki lekarskiej przez pryzmat sześciu, zdaniem autora, głównych problemów, z jakimi w przeszłości mierzyła się medycyna i z jakimi nadal przychodzi jej się mierzyć. Pierwsza odsłona to rozważania o konstrukcji (lub inaczej – budowie) organizmu człowieka, nad którą dyskutowali badacze zajmujący się takimi dyscyplinami, jak anatomia, histologia, cytologia i genetyka. Druga odsłona jest próbą zrozumienia funkcji życiowych, czyli przedmiotu badań nauk eksperymentalnych, przede wszystkim fizjologii i biochemii. Trzecia wiąże się z poznaniem przyczyn i mechanizmów, które uszkadzają lub niszczą strukturę i zaburzają funkcje organizmu, czyli zdarzeń i procesów stojących u podstaw nauki o chorobach – patologii wraz z anatomią patologiczną, patomorfologią i patofizjologią, mikrobiologią i bakteriologią lekarską. Dzięki czwartej odsłonie zbliżamy się do historii prób rozpoznania procesów chorobowych oraz zdolności przewidywania ich dalszego biegu. To świat diagnostyki i prognostyki medycznej. Piąta ukazuje zaś poszukiwania metod i środków, których celem staje się przywrócenie zaburzonej homeostazy organizmu – a więc to, co określamy mianem terapii. Ostatnia, szósta, przedstawia dzieje chirurgii – nauki i sztuki poszukującej sposobów bezpośredniego wniknięcia w przestrzeń konstrukcji organizmu i przywrócenia właściwego biegu funkcji życia. W chwili obecnej do rąk Czytelników trafia druga część, obejmująca odsłony czwartą i piątą. Ryszard Gryglewski

Based on the phenomenon, the authors were moved to seek a solution of a sensible way of view and religious attitude (taking a middle and peaceful path) through religious moderation performed by the Nahdlatul Ulama and the Muhammadiyah. This type of research is field research with a qualitative approach, and the method used is a comparative description. A combination of interviews, observation, and documentary studies do the writer’s data collection. As for the analysis, the authors used descriptive analytic data analysis techniques. According to research, Nahdlatul Ulama is an Islamic organization practicing modernity and religion, accommodating tradition and culture, culinary activity, and its deep-rooted message base. In comparison, Muhammadiyah’s religious moderation was performed through Muhammadiyah charity enterprises in formal education, health, and religious dialogue. Nahdlatul Ulama and Muhammadiyah, in certain aspects, are different, though not principles, only branches in the doctrine of Islam. When it comes to religious moderation, both are moderate, having a tolerant attitude with members of other faiths and those of differing religious people, being impartial and neither extreme.

Published: January 2023

Investors find it very appealing to invest in the form of shares for State-Owned Enterprises (BUMN) because these businesses have capital that is entirely or largely owned by the government. Not affected by the Covid-19 pandemic shock, investors think that the price of BUMN shares in the infrastructure sector offers excellent corporate value. The Covid-19 pandemic has slowed Indonesia's economic expansion, since February 2020. It should be remembered that many businesses have experienced negative corporate profitability at some point. With financial risk and profitability acting as intermediary variables, this study seeks to determine the degree to which the independent variables of investment decisions, funding decisions, and macroeconomics influence the dependent variable, namely company value. This quantitative study employs a census sampling technique at seven state-owned infrastructure companies from 2014 to 2021. This study employs SEM analysis (Structural Equation Modeling) based on components or variants, namely Partial Least Squares (PLS), with the help of Smart PLS 4.0 software. The study's findings indicate that macroeconomics has no direct and significant impact on financial risk. It does, however, have a significant impact on profitability and company value. Financial risk and profitability are unaffected by investment decisions. It does, however, have a significant impact on company value. Funding decisions have no direct influence on company value. It does, however, have a significant impact on financial risk and profitability. Financial risk has no direct influence on company value. Profitability has no direct influence on company value. For the indirect relationship between the financial risk and profitability variables, it does not mediate the x versus y variables.

Published: January 2023

Publishing in the prestigious research avenues is considerable important for the researchers and academicians. However, selecting the right journal to suit the research topic and quality of research is a tiresome task. Studying the nature of the research published in differently ranked journals is important to understand the difference of research and publication trends. This study aims to examine a differences and similarities of the research published in the Q1 and Q4 ranked Library and Information Science (LIS). A total 21,437 documents were selected from WoS Q1 and Q4 category LIS journals for this study. Then the data of Q1 and Q4 journals was separately accessed, analyzed and compared with different tool including MS Access, MS Excel, Gaphi, Biblioshiny, and VOS Viewer software. We found significant differences in the LIS research themes and publication trends between the Q1 and Q4 category publications. The Q1 journals are publishing on emerging bibliometrics, technology related topics like social media, information systems, machine learning etc., innovating practices and research. While, Q4 journals mostly publish about academic libraries, information seeking, literacy and behavioral research. Topical evaluation reveled citation analysis, bibliometrics, social media, innovation and collaboration as emerging topics in both Q1 and Q4 category journals but differ in terms of total publications order. This is the first study to the best knowledge or understanding by the authors to examining the similarities and differences in a Q1 and Q4 ranked LIS journals related to the research trends, publishing institution, individuals, countries, etc. It also identifies and compares the Q1 and Q4 journal's major research topics, topical evolution over years, most citied research themes that can also be considered a novel contribution to the field. This study provides a holistic overview of topical evolution and emerging research foci for the LIS researchers, especially early career researchers, academicians, and research students to make right decisions for research topic, publication avenues, collaborators, and potential areas of interest to attract research grants. This method of comparing category-based research trends can assist library practitioners working for research support and information literacy to assist their users in the selection of topics for potential publications and publication avenues to create impact.

O desenvolvimento das atividades humanas ocasiona impactos aos recursos naturais podendo comprometer o desenvolvimento sustentável. Nesse contexto, objetivou-se com o presente trabalho analisar a dinâmica espacial e temporal da cobertura do solo na microbacia e zona ripária do rio Joaninha, com a finalidade de conhecer os impactos provocados pelas atividades antrópicas e selecionar práticas de manejo para mitigar esses impactos. Para realização deste trabalho foram utilizadas imagens dos satélites Landsat 5 e Landsat 8, e geotecnologias. Em 38 anos de colonização (1984 a 2022), a área de floresta nativa foi reduzida de 4,55 para 0,82 km2 na microbacia e de 0,23 para 0,14 km2 na zona ripária. Em contrapartida, a área de agropecuária aumentou de 1,95 para 5,67 km2 na microbacia e de 0,26 para 0,34 km2 na zona ripária. No ano de 2022, a cobertura do solo era composta principalmente de agropecuária, chegando a ocupar 87,23% e 69,39% das áreas totais da microbacia e zona ripária, respectivamente. Conclui-se que a supressão excessiva da floresta nativa na microbacia e o avanço da agropecuária na zona ripária comprometem o desenvolvimento sustentável da região, por impactarem negativamente a qualidade do solo e a disponibilidade de recursos hídricos. Recomenda-se de forma integrada, a manutenção da vegetação nativa remanescente, recuperação da vegetação nativa nas áreas protegidas por lei que atualmente estão com agropecuária, a inclusão do componente florestal nas atividades produtivas (ex: sistema agroflorestal) e a adoção de práticas conservacionistas nos sistemas agropecuários.

Abstract. Atmospheric methane (CH4) concentrations have more than doubled since the beginning of the industrial age, making CH4 the second most important anthropogenic greenhouse gas after carbon dioxide (CO2). The oil and gas sector represent one of the major anthropogenic CH4 emitters as it is estimated to account for 22 % of global anthropogenic CH4 emissions. An airborne field campaign was conducted in April–May 2019 to study CH4 emissions from offshore gas facilities in the Southern North Sea with the aim to derive emission estimates using a top-down (measurement-led) approach. We present CH4 fluxes for six UK and five Dutch offshore platforms/platform complexes using the well-established mass balance flux method. We identify specific gas production emissions and emission processes (venting/fugitive or flaring/combustion) using observations of co-emitted ethane (C2H6) and CO2. We compare our top-down estimated fluxes with a ship-based top-down study in the Dutch sector and with bottom-up estimates from a globally gridded annual inventory, UK national annual point-source inventories, and with operator-based reporting for individual Dutch facilities. In this study, we find that all inventories, except for the operator-based facility-level reporting, underestimate measured emissions, with the largest discrepancy observed with the globally gridded inventory. Individual facility reporting, as available for Dutch sites for the specific survey date, shows better agreement with our measurement-based estimates. For all sampled Dutch installations together, we find that our estimated flux of (122.7 ± 9.7) kg h-1 deviates by a factor 0.7 (0.35–12) from reported values (183.1 kg h-1). Comparisons with aircraft observations in two other offshore regions (Norwegian Sea and Gulf of Mexico) show that measured, absolute facility-level emission rates agree with the general distribution found in other offshore basins despite different production types (oil, gas) and gas production rates, which vary by two orders of magnitude. Therefore, mitigation is warranted equally across geographies.

Abstract. In the summer of 2018, Europe experienced an intense heat wave which coincided with several persistent large-scale ozone (O3) pollution episodes. Novel satellite data of lower tropospheric column O3 from the Global Ozone Monitoring Experiment-2 (GOME-2) and Infrared Atmospheric Sounding Interferometer (IASI) on the MetOp satellite showed substantial enhancements in 2018 relative to other years since 2012. Surface observations also showed ozone enhancements across large regions of continental Europe in summer 2018 compared to 2017. Enhancements to surface temperature and the O3 precursor gases carbon monoxide and methanol in 2018 were co-retrieved from MetOp observations by the same scheme. This analysis was supported by the TOMCAT chemistry transport model (CTM) to investigate processes driving the observed O3 enhancements. Through several targeted sensitivity experiments we show that meteorological processes, and emissions to a secondary order, were important for controlling the elevated O3 concentrations at the surface. However, mid-tropospheric (~500 hPa) O3 enhancements were dominated by meteorological processes. We find that contributions from stratospheric O3 intrusions ranged between 15–40 %. Analysis of back trajectories indicates that the import of O3-enriched air masses into Europe originated over the North Atlantic substantially increasing O3 in the 500 hPa layer during summer 2018.

Abstract. The provision of climate-neutral, sustainable, and independent heat sources is an essential part of the ongoing transformation of heating systems in Germany. The city of Minden, located at the junction of the river Weser and the Middleland Canal, with its strong industrial sector, faces a massive transition of how heat and energy will be provided for industrial processes as well as heating in the commercial and residential sectors. In our study, we evaluate the structural requirements for the exploitation and utilization of deep geothermal energy from regional Mesozoic rocks, which are known to source thermal springs in the greater Minden area, and geothermal projects in other parts of the North German Basin. The compilation of geological data, seismic data, and rock properties from wells is used to construct a regional structural model as well as temperature distributions based on depth uncertainties of the respective stratigraphic units. Our investigations indicate several stratigraphic units ranging from the Middle Jurassic, Keuper, and Muschelkalk to the Middle Bunter at depths greater than 4100 m below mean sea level with suitable temperatures greater than 150 ∘C. Seismic data reveal the presence of faults, which may act as a conduit for thermal waters in the northern part of Minden. Our study also provides a basis for further geothermal exploration and exploitation south of Minden, where an operating geothermal system has already been established in the city of Osnabrück and further north, where the potential reservoirs are located at greater depths as shown by hydrocarbon exploration data. First estimations of the geothermal power output for two selected reservoir horizons yield up to 11.3 and 14.3 MW (10 % probability to yield these or higher values), respectively. We conclude that the subsurface of the inverted part of the Lower Saxony Basin principally fulfills the requirements (formation temperatures) for deep geothermal production not only for residential and commercial use but also for industrial processes. However, future detailed reservoir analyses and thermo-hydraulic investigations on a regional scale require additional exploration work like newly acquired seismic surveys and deep exploration wells.

Abstract. Volumetric measurements of the ionosphere are important for investigating spatial variations of ionospheric features, like auroral arcs and energy deposition in the ionosphere. In addition, such measurements make it possible to distinguish between variations in space and time. While spatial variations in scalar quantities such as electron density or temperature have been investigated with incoherent scatter radar (ISR) before, spatial variation in the ion velocity, which is a vector quantity, has been hard to measure. The upcoming EISCAT3D radar will be able to do volumetric measurements of ion velocity regularly for the first time. In this paper, we present a technique for relating volumetric measurements of ion velocity to neutral wind and electric field.
To regularize the estimates, we use Maxwell's equations and fluid-dynamic constraints.
The study shows that accurate volumetric estimates of electric field can be achieved. Electric fields can be resolved at altitudes above 120 km, which is the altitude range where auroral current closure occurs. Neutral wind can be resolved at altitudes below 120 km.

Abstract. Nano-darcy level permeability measurements of porous media, such as nano-porous mudrocks, are only practically feasible with gas invasion methods into granular-sized samples with short diffusion lengths and thereby reduced experimental duration; however, these methods lack rigorous solutions and standardized experimental procedures. For the first time, we resolve this by providing an integrated technique (termed as gas permeability technique) with coupled theoretical development, experimental procedures, and data interpretation workflow. Three exact mathematical solutions for transient and slightly compressible spherical flow, along with their asymptotic solutions, are developed for early- and late-time responses. Critically, one late-time solution is for an ultra-small gas-invadable volume, important for a wide range of practical usages. Developed as applicable to different sample characteristics (permeability, porosity, and mass) in relation to the storage capacity of experimental systems, these three solutions are evaluated from essential considerations of error difference between exact and approximate solutions, optimal experimental conditions, and experimental demonstration of mudstone and molecular-sieve samples. Moreover, a practical workflow of solution selection and data reduction to determine permeability is presented by considering samples with different permeability and porosity under various granular sizes. Overall, this work establishes a rigorous, theory-based, rapid, and versatile gas permeability measurement technique for tight media at sub-nano darcy levels.

Abstract. Decreasing sea ice extent in summer caused by climate change is affecting the carbon cycle of the Arctic Ocean. In this study, surface sediments across the western Arctic Ocean are investigated to characterize sources of sedimentary organic carbon (OC). Bulk organic parameters (total organic carbon, total nitrogen, δ13Corg and δ15N) combined with molecular organic biomarkers (e.g., sterols and highly branched isoprenoids (HBIs)) are applied to distinguish between sympagic, pelagic, and terrestrial OC. Furthermore, downcore profiles of these parameters were also generated from the Chukchi Sea R1 core (74° N) to evaluate changes in the relative contribution of these three components of sedimentary OC over the last 200 years with decreasing sea ice. Our data evidence that from 1820s to 1930s, prevailing high and variable sea ice cover inhibited in situ primary production resulting in prominent land-derived material stored in sediments. From 1930s to 1980s, with the gradual decline of sea ice, primary production increased progressively. The ratio of sympagic and pelagic OC began to rise to account for a larger portion of sedimentary OC. Since 1980s, accelerated sea ice loss led to enhanced primary production, stabilizing over the last decades due to freshwater induced surface ocean stratification in summer.

Abstract. Marine diazotrophs convert dinitrogen (N2) in seawater into bioavailable nitrogen (N), contributing approximately half of the external input of bioavailable N to the global ocean. A global oceanic diazotroph database was previously published in 2012. Here, we compiled version 2 of the database by adding 23,095 in situ measurements of marine diazotrophic abundance and N2 fixation rates published in the past decade, increasing the number of N2 fixation rates and microscopic and qPCR-based diazotrophic abundance data by 140 %, 26 % and 443 %, respectively. Although the updated database expanded spatial coverage considerably, particularly in the Indian Ocean, the data distribution was still not uniform and most data were sampled in the surface Pacific and Atlantic Oceans. By summing the arithmetic means of the N2 fixation rates in each ocean basin, the updated database substantially increased the estimate of global oceanic N2 fixation from 137 ± 9 Tg N yr-1 using the old database to 260 ± 20 Tg N yr-1 (mean ± standard error). However, using geometric means instead, the updated database gave an estimate of global oceanic N2 fixation (60 Tg N yr-1) similar to that estimated from the old database (62 Tg N yr-1), while the new estimate had a larger uncertainty (confidence intervals based on one standard error: 47 – 107 Tg N yr-1 versus 52 – 73 Tg N yr-1), mostly attributable to elevated uncertainties in the Pacific Ocean. An analysis comparing N2 fixation rates measured at the same months and location (1° × 1° grids) showed that the new 15N2 dissolution method obtained N2 fixation rates higher than the conventional 15N2 bubble method in 65 % of cases, with this percentage increasing when the N2 fixation rates were high (> approximately 3 μmol N m-3 d-1 using the 15N2 dissolution method). With greatly increased data points, this version 2 of the global oceanic diazotrophic database can support future studies in marine ecology and biogeochemistry. The database is stored at the Figshare repository (https://doi.org/10.6084/m9.figshare.21677687) (Shao et al., 2022).
