Bronchiolitis obliterans caused by CMV in a previously healthy Asian infant
Authors: Byun Shin Yun , Kim Myo Jing , Lee Young Seok , Kang Eun Ju , Jung Jin A
Published: April 2024

Cytomegalovirus (CMV) is currently the most common cause of congenital infection and the leading infectious cause of brain damage and hearing loss in children. Perinatal CMV infection rarely causes clinical manifestations in normal individuals and usually follows a benign course in immunocompetent infants. However, ~15-25% of infected preterm infants may develop pneumonia, hepatitis or sepsis-like illness, bradycardia, hepatosplenomegaly, distended bowel, anemia, or thrombocytopenia. Bronchiolitis obliterans (BO) is a rare, fibrosing form of chronic obstructive lung disease that follows severe insults to the lower respiratory tract and results in narrowing and/or complete obliteration of the small airways. In non-transplant children, the most common form of BO is a severe lower respiratory tract infection, especially of adenovirus. We experienced a case of a 37-day-old male who was diagnosed as BO on chest computed tomography (CT) after CMV pneumonia. To our best knowledge, this is the first case of BO caused by CMV pneumonia in a healthy infant.

La “Finca Tradicional Econativa” del norte del Cauca, Colombia: una interpretación desde Yi-Fu Tuan
Authors: Uribe Castro Hernando
Published: April 2024

Este artículo tiene como propósito realizar una interpretación de ese lugar emblemático que representa la finca tradicional econativa para las sociedades negras del norte del Cauca a la luz de la perspectiva teórica de un geógrafo como Yi-Fu Tuan. Las principales categorías que se movilizan desde esta perspectiva teórica son el símbolo público y el área de cuidado. Los principales resultados, dada la implementación de esta perspectiva teórica, es comprender cómo un lugar cuando es catalogado como “lugar ancestral”, rompe no solo con una visión lineal del tiempo social (pasado, presente y futuro) sino también que adquiere todo un sentido de lugar que lo transmuta como símbolo público y como un área de cuidado con el que se argumenta la pervivencia de la comunidad hacia el porvenir a pesar de encontrarse en escenarios territoriales de fuertes tensiones sociales.  
Algunas de las principales conclusiones que propone el texto que, para los pobladores negros del norte del Cauca, uno de los lugres más cargados de simbolismo es la denominada Finca Tradicional Econativa. Ella representa tiempo-espacio de resistencia, y expresión de sus luchas por la propiedad de la tierra y la defensa del territorio frente a los intentos expansivos de los empresarios del capital agroindustrial cañero. El avance agroindustrial sobre el territorio por más de un siglo significó para las sociedades negras la pérdida de sus tierras como morada. Dada la complejidad social (política y económica) de esta lucha, han tenido que recurrir a estructurar formas de organización social de base para enfrentar los embates del capitalismo agrícola.
Effects of Thermal Expansion and Pressure on Far-Field Fluctuations of Heterogeneous Propellants
Authors: Brown Kevin C. , Jackson Thomas L.
Published: April 2024

In this work, we carry out three-dimensional mesoscale simulations of heterogeneous solid propellant combustion. We solve the reactive low-Mach-number equations in the gas phase with complete coupling to the solid phase. The model takes into account thermal expansion and deformation in the solid phase by using a hypoelastic law in the quasi-static limit. To account for morphology, we select two different propellant formulations with different particle size distributions and present the results as a function of pressure. The thermomechanical behavior is accessed by examining quantities such as strain and stress in the propellant as a function of pressure and propellant morphology. We also show that temperature and velocity fluctuations exist in the far field above the propellant surface and that these fluctuations can be significant. To better understand the nature of these fluctuations, we vary the pressure and make relevant plots of normal velocity and temperature probability density functions, as well as time autocorrelations. Such descriptions are necessary to account for the coupling between the mesoscale and the macroscale, where the fluctuations at the mesoscale can affect quantities at the macroscale, such as head-end pressure, trigger parietal vortex shedding, and aeroacoustics.

Published: April 2024

Background:

Bilateral vertebral artery dissection aneurysm (VADA) is a rare condition that leads to severe stroke. However, the surgical strategy for its treatment is controversial because the pathology is very complicated and varies in each case. Here, we report a case of bilateral VADA that was successfully treated with staged bilateral VADA occlusion and low-flow bypass.

Case Description:

A Japanese man in his 40s presented with bilateral VADA with subarachnoid hemorrhage. He had only mild headaches without any other neurological deficits. Subsequently, the ruptured left VADA was surgically trapped. However, on postoperative day 11, the contralateral VADA enlarged. The right VADA was then proximally clipped via a lateral suboccipital approach. Furthermore, a superficial temporal artery–superior cerebellar artery bypass was performed through a subtemporal approach in advance to preserve cerebral flow in the posterior circulation. The bilateral VADA was obliterated, and the patient had an uneventful postoperative course during the 1-year and 6-month follow-up period.

Conclusion:

Bilateral VADA can be successfully treated with staged bilateral VADA obstruction and low-flow bypass. In this case, as the posterior communicating arteries were the fetal type and the precommunicating segments of the posterior cerebral arteries (P1) were hypoplastic, a low-flow bypass was used to supply the basilar and cerebellar arteries, except the posterior cerebral and posterior inferior cerebellar arteries. Furthermore, low-flow bypass is a less invasive option than high-flow bypass.
Detailed Complementary Consistency: Wave Function Tells Particle How to Hop, Particle Tells Wave Function How to Collapse
Authors: Huang Lei , Shi Zhecun , Wang Linjun
Published: April 2024

In mixed quantum-classical dynamics, the time evolution of the quantum subsystem can involve both wave function and particle-like descriptions, which may yield inconsistent results for the expectation value of the same physical quantity. In this study, we propose a novel detailed complementary consistency (DCC) method, which achieves fully consistent results based only on the principle of internal consistency in nonadiabatic dynamics. Namely, wave function tells particle how to hop along each trajectory, while particle tells wave function how to collapse based on the occupation of active states. As benchmarked in a diverse array of representative models, DCC not only gives identical populations based on both wave functions and active states, but also closely and systematically reproduces the exact quantum dynamics. Due to the high performance, our new DCC method provides a promising approach toward more consistent mixed quantum-classical description of nonadiabatic dynamics with much better reliability and efficiency for general applications.

Published: April 2024

Unnatural amino acids (UAAs) have shown great potential to enhance the pharmacological properties of peptides and represent a key motif in a wide range of biologically relevant natural products. Herein, we disclose a protocol that facilitates the asymmetric synthesis of UAAs from widely abundant amines through photoredox-mediated α-amino C–H bond activation. The platform utilizes either the strongly oxidizing organic acridinium or decatungstate as a photocatalyst to generate α-amino radicals from a variety of amines, which are then effectively coupled with a chiral glyoxylate-derived N-sulfinyl imine. The disclosed platform provides a general entry to various decorated unnatural α-amino acid derivatives, accommodating a diverse array of functional groups.

Published: April 2024

Herein, Mn3O4 spherical particles (SPs) were synthesized by the sol-gel process, followed by thermal annealing at 400 °C. The sample was analyzed by XRD, FTIR, SEM, SBET, XPS, H2-TPR and UV-vis spectroscopy. XRD and FTIR analysis show that Mn3O4 exhibits a tetragonal spinel structure. SEM and SBET analysis display a porous homogeneous surface made of strongly agglomerated spherical-like grains size with an estimated average particle size of ~35 nm, corresponding to a large specific surface area (SBET) of ~81.5 m2/g. XPS analysis indicated that, Mn3O4 were composed of metallic cations (Mn4+, Mn3+, Mn2+) and oxygen species (O2-, OH- and CO32-). The optical energy band gap energy was ~2.55eV. Moreover, Mn3O4 SPs were successfully tested as catalyst with almost 100% conversion of CH4 to CO2 and H2O at a gas hourly space velocity (GHSV) of 72 000 mL3.g-1h-1. The observed performance can be assigned to the cooperated effects of the smallest spherical-like grain size with mesoporous structure as responsible for the larger SBET, and the available surface-active oxygenated species. The cooperative effect of the good reducibility, the higher ratio of active species (OLat/OAds), as well as Density Functional Theory (DFT) calculations suggested that, CH4 total oxidation over the mesoporous Mn3O4 SPs might follow a two-term process in which both Langmuir-Hinshelwood and Mars-van Krevelen mechanisms are cooperatively involved.
Modelling the Impact of Mass Transport in a Miniplant Photoreactor
Authors: Gaulhofer Florian , Becker Henning , Peschl Alexander , Ziegenbalg Dirk
Published: April 2024

The scale-up of photoreactions posses challenges due to the non-linear coupling of the radiation field with reaction kinetics and mass transport. A knowledge-based scale-up requires a sufficiently detailed theoretical description of these processes. In this work, a transient, two-dimensional photoreactor model is proposed and used to systematically investigate mass transport limitations in photoreactors, including the effect of transverse mass transfer through static mixers and the self-shadowing effect of the photoisomerization of spyropyrane. The proposed photoreactor model indicated that the installation of static mixers would increase the transverse dispersion by a factor of 600, which would allow the conversion to be tripled in an up-scaled photoreactor. Furthermore, a shrinking reaction zone was observed when increasing the light power, emphasizing the importance of mass transport for scaling photoreactors.
Computationally predicting the performance of gas sensor arrays for anomaly detection
Authors: Morris Paul , Simon Cory
Published: April 2024

In many gas sensing tasks, we simply wish to become aware of gas compositions that deviate from normal, "business-as-usual" conditions. We provide a methodology, illustrated by example, to computationally predict the performance of a gas sensor array design for detecting anomalous gas compositions. Specifically, we consider a sensor array of two zeolitic imidazolate frameworks (ZIFs) as gravimetric sensing elements for detecting anomalous gas compositions in a fruit ripening room. First, we define the probability distribution of the concentrations of the key gas species (CO₂, C₂H₄, H₂O) we expect to encounter under normal conditions. Next, we construct a thermodynamic model to predict gas adsorption in the ZIF sensing elements in response to these gas compositions. Then, we generate a synthetic training data set of sensor array responses to "normal" gas compositions. Finally, we train a support vector data description to flag anomalous sensor array responses and test its false alarm and missed-anomaly rates under conceived anomalies. We find the performance of the anomaly detector diminishes with (i) greater variance in humidity, which can mask CO₂ and C₂H₄ anomalies or cause false alarms, (ii) higher levels of noise emanating from the transducers, and (iii) smaller training data sets. Our exploratory study is a step towards computational design of gas sensor arrays for anomaly detection.
Adsorption of the anticancer drug 5-fluorouracil in faujasite-type zeolites studied with density functional theory calculations
Authors: Fischer Michael
Published: April 2024

Zeolites have been proposed as carrier materials for the encapsulation and controlled release of the anticancer drug 5-fluorouracil (5-FU). Besides, they could also find use in the adsorption-based removal of 5-FU from water, for example in the treatment of hospital effluents. In the present work, dispersion-corrected density functional theory (DFT) calculations and DFT-based ab initio molecular dynamics (AIMD) simulations are employed to study the interaction of 5-FU with faujasite-type zeolites having different Si/Al ratios. Comparing distinct local arrangements of Al atoms and charge-balancing protons, it is evaluated to what extent “multi-site” interactions, i.e., interactions of 5-FU with more than one proton, affect the adsorption energy. Additionally, infrared spectra are predicted for selected low-energy configurations in order to facilitate an experimental identification of different bonding environments. Typically, several hydrogen bonds are formed between 5-FU and the framework, and the stability of these bonds at room temperature is probed with AIMD simulations. While they are largely stable in the absence of water, competitive adsorption of water molecules results in a breaking of hydrogen bonds, framework deprotonation, and a displacement of 5-FU from its initial position. Exposure of dehydrated 5-FU@FAU composites to water might thus be a useful approach to trigger 5-FU release in drug delivery applications.
Acceso, usos de las TIC y competencia digital autopercibida en estudiantes de ingeniería. Antes, durante y después de la virtualidad forzada por el covid-19
Authors: Chiecher Analía Claudia
Published: April 2024

La competencia digital es de vital importancia en el mundo contemporáneo. Estudios diversos han demostrado que, aunque los jóvenes son usuarios de las tecnologías, sus habilidades para utilizarlas con finalidades de aprendizaje no están altamente desarrolladas ni homogéneamente distribuidas. La hipótesis que orienta el trabajo afirma que la experiencia de aprendizaje en contextos virtuales durante la pandemia podría haber tenido incidencia en ciertos usos de las tecnologías. Se realizó un estudio no experimental, transversal, descriptivo y comparativo del que participaron 3 grupos de estudiantes de ingeniería (n= 907), quienes dieron respuesta a un cuestionario antes (grupo 1, n=555), durante (grupo 2, n=215) y después de la pandemia (grupo 3, n=137). Los resultados muestran diferencias entre los grupos en relación con algunas variables vinculadas con las autopercepciones de competencia digital y el uso de tecnologías. La discusión gira en torno de iluminar la importancia de enseñar la competencia digital en contextos educativos.

Modifications of Classical Surface Reconstruction Algorithms for Visualization of a Function Defined on a Rectangular Grid
Authors: Munts N.V. , Kumkov S.S.
Published: April 2024

In the paper, modifications of visualization algorithms for real-valued functions of two and three arguments given on a rectangular or parallelepipedal grid are considered. In the case of two arguments, the graph of the function is a surface embedded into the three-dimensional space. The majority of scientific visualization systems offer visualization procedures for such surfaces, but they construct them under the assumption that the functions are continuous. In the paper, for the case of a discontinuous function, a modification of this algorithm is proposed. In addition, the algorithm removes “plateaus” that occur after cutting the function at some level (in order to remove too large values).

Visualization of a function of three arguments implies showing its level sets, that is, regions of the space of arguments where the magnitudes of the function do not exceed a certain value. In the case of a grid function, such sets are “voxel” sets, that is, they are composed of grid cells. With that, some smoothing of the surface of such sets is required, which is carried out by the Marching Cubes algorithm and algorithms of the Laplacian family. A modification of the Marching Cubes algorithm is proposed, which preserves the symmetry of the set surface with respect to the coordinate planes, axes, or some point, if the rendered set has such a symmetry.
Multiple Cubes Growth Algorithms for Simple Representative Elementary Volume Determination on 3D Binary Images
Authors: Kadyrov R. I.
Published: April 2024

Porosity analysis is fundamental for understanding various material properties and transport phenomena in scientific and engineering disciplines. This study delves into the challenging task of determining the representative elementary volume (REV) in porous media, crucial for accurate analyses. Two novel algorithms, Center-Corner Cubes Growing (3CG) and Random Cubes Growing (RCG), were proposed and tested on synthetic body-centered cubic (BCC) sphere packing and natural porous structures of Berea sandstone and Indiana limestone, obtained using µCT. First algorithm (3CG) operates by analyzing porosity within cubes growing from each of the eight corners and a central region of a 3D binarized stack. In contrast, the Random Cube Growing (RCG) algorithm randomly selects seed points within the 3D stack and grows cubic regions around them. Both algorithms systematically compute porosity for various cube sizes, determining the average porosity and standard deviation for each extent. These visual analytics tools contribute to identifying the specific size ranges where porosity curves converge and stabilize, indicating potential REV within the material. While 3CG simplifies the approach by focusing on a limited number of curves, RCG provides a broader view, capturing diverse porosity patterns. The absence of consistent local minima in certain cases indicates high porosity heterogeneity and the impossibility of achieving REV in certain sample sizes.

Published: April 2024

With the electromagnetic environment becoming increasingly complex, it is crucial to address the risk posed by electromagnetic pulse, which critically impairs the performance and reliability of electronic systems based on complementary metal oxide semiconductor (CMOS) image sensors. In this context, research on the failure types of CMOS image sensors in a high-power electromagnetic environment, caused by strong electromagnetic pulses and the rapid evaluation method of interference immunity, has garnered significant interest. This paper conducts electromagnetic pulse simulation experiments on CMOS image sensors to first study their failure types, such as image abnormalities and functional interruption, and then identify the corresponding failure criteria. Furthermore, this study builds on the small sample test evaluation method to investigate the interference threshold of functional interruptions in CMOS image sensors by calculating the failure probability at different field strengths. The obtained data were combined with the Weibull distribution function for fitting, the results of which found the interference threshold to be at 40.4 kV/m. The findings of this study provide a basis for evaluating the survivability of CMOS image sensors and their associated reinforcement technology in high-power electromagnetic environments.

Authors: Han Seong-Hee , Kim Dong-Wook
Published: April 2024

This paper employs the 0.2 μm ETRI GaN HEMT process on SiC to develop a Ku-band GaN low-noise amplifier monolithic microwave integrated circuit (MMIC) characterized by high-input power robustness for radar transceiver modules. A source degeneration inductor is employed to obtain the proposed amplifier’s stable operation and the compromised impedance trajectory of the maximum available gain and minimum noise figure. The analysis results show simultaneous gain and noise impedance matching, achieved using only a small number of passive elements. Furthermore, the proposed low-noise amplifier MMIC secures a linear gain of 21.3−22.6 dB, an input return loss of 19.6−21.4 dB, and a noise figure of 1.7−1.8 dB in the 15–16 GHz frequency range. It also exhibits an input 1 dB compression point of 0.4−1.5 dBm in the single-tone power test, and an input third-order intercept point of 5.8−10.1 dBm within the 15−16 GHz frequency range in the two-tone intermodulation distortion test.
Inverse Design of Electromagnetic Metasurfaces Utilizing Infinite and Separate Latent Space Yielded by a Machine Learning-Based Generative Model
Authors: Kim Jong-Hoon , Hong Ic-Pyo
Published: April 2024

This study proposes an inverse design framework for metasurfaces based on a neural network capable of generating infinite and continuous latent representations to fully span the electromagnetic metasurfaces (EMMS) property space. The inverse design of EMMS inherently poses the one-to-many mapping problem, since one set of electromagnetic properties can be provided by many different shapes of scatterers. Previous studies have addressed this issue by introducing machine learning-based generative models and regularization strategies. However, most of these approaches require highly complex operating configurations or external modules for preprocessing datasets. In contrast, this study aimed to construct a more streamlined and end-to-end solver by building a network to process multimodal datasets and then incorporating a classification scheme into the network. The validity of the idea was confirmed by comparing the accuracy of the results predicted by the proposed approach and the outcomes simulated using PSSFSS.

Authors: Deokar D. , Tayade S.B. , Funde S. , Bhosale B. , Dalvi S.
Published: April 2024

In the present study, we report the room temperature synthesis of a novel two-dimensional (2D) coordination polymer (CP) having the formula {[Cd(H-PCA)2(H2O)].0.5(H2O).0.5(CH3OH)}n (CP1), where H-PCA represents 4-pyrazolecarboxylate. The synthesis of CP1 was achieved through a one-pot reaction, involving the self-assembly of Cd(OAc)2·2H2O and the multitopic mixed N- and O-donor ligand, 4-pyrazolecarboxylic acid (H2-PCA), in methanol. This method demonstrated high yield and purity, enabling the facile production of multigram quantities of CP1 within a short timeframe. Notably, the synthetic procedure selectively deprotonates the carboxylic acid group while retaining the pyrazole moiety in its protonated form.CP1 has been thoroughly characterized using various analytical techniques, including single-crystal X-ray diffraction, FTIR spectroscopy, elemental analysis, scanning electron microscopy, thermogravimetric analysis, and powder X-ray diffraction. The structural analysis revealed that CP1 features a 3, 5-connected binodal net with the point symbol {4.5.6}{4.55.63.7}, leading to a unique –ths net topology. Through hydrogen bonding connections between adjacent 2D sheets, CP1 further extends into a three-dimensional (3D) supramolecular network due to the presence of coordinated water molecules and the protonated pyrazole group. Additionally, a 3D Hirshfeld Surface analysis accompanied by quantitative 2D fingerprint plots was also investigated to explore the intermolecular interactions.

Published: April 2024

Background: The maternal mortality rate is the number of maternal deaths resulting from pregnancy, childbirth and postpartum processes, which is an indicator of women's health status. Efforts that can be made to accelerate the reduction in maternal mortality are by ensuring that every mother is able to access quality health services. Low-dose aspirin has been proven to be a safe and effective primary prevention of preeclampsia. This study aims to determine the effect of low dose aspirin on the incidence of preeclampsia.

Subjects and Method: Cross sectional research was conducted at the Community Health Center, Blora, Central Java, Indonesia. A sample of 200 pregnant women was selected using random sampling. The dependent variable is preeclampsia. The independent variables are age, income, aspirin consumption, primigravida, multigravida and hypertension. Data were collected by questionnaire and analyzed by multiple logistic regression.

Results: The results of logistic regression analysis in this study concluded that the risk of preeclampsia increased at age <20 years or ≥35 years (OR= 4.62; 95% CI= 1.89 to 11.28; p= 0.001), gravida 2-3 (OR= 3.03; CI 95 %= 1.01 to 9.05; p= 0.047), gravida ≥3 (OR= 4.41; 95% CI= 1.07 to 18.18; p= 0.040) and history of hypertension (OR= 2.41; 95% CI= 1.02 to 5.69; p= 0.005 ). The risk of preeclampsia decreased with income > IDR 2,000,000 (OR= 0.44; 95% CI= 0.22 to 0.87; p= 0.019) and administration of low-dose aspirin (OR= 0.13; 95% CI= 0.05 to 0.35; p <0.001).

Conclusion: The risk of preeclampsia increases with age, gravida 2-3, gravida ≥3 and history of hypertension. The risk of preeclampsia decreases with high income and administration of low-dose aspirin.

Method of improving the production manufacturability of the product design
Authors: Bazrov B. M. , Kheifetz M. L.
Published: April 2024

Due to the customization of production, it becomes especially important to test the design of the product for manufacturability at all stages of its creation. A method is proposed to improve the manufacturability of the product design at the stage of developing the working documentation of the product, based on its evaluation by summing the coefficients of manufacturability. The method consists in constructing a regression series of product design characteristics according to the degree of reduction of their impact on the complexity of the design and establishing the sequence of its improvement. It is recommended to improve manufacturability and reduce the labor intensity of manufacturing a product, to pay attention from the beginning to methods for achieving accuracy during assembly, as well as the use of the maximum number of purchased parts in assemblies; then on the repeatability of the types of connections of parts in the design, reducing the number of types and laboriousness of making connections, and finally on the repeatability of parts in the overall design, the maximum use of borrowed parts. It is shown that the typification of processes and the unification of structures can be effectively dealt with at the level of large associations (holdings, concerns) and especially industries.

O envelhecimento da população é uma realidade nacional e global. Nesse sentido, é pertinente discutir problemáticas que envolvem a senilidade, como a prevalência das Doenças Crônicas não Transmissíveis (DCNTs) as quais compreendem um dos principais motivos para a diminuição na funcionalidade dos idosos. Nesta perspectiva, o objetivo desta pesquisa foi avaliar a capacidade funcional de idosos que fazem parte de um projeto social comunitário. Trata-se de um estudo observacional, transversal, com abordagem quali-quantitativa. Foram incluídos todos os idosos, de ambos os sexos cadastrados no projeto social, e excluídos os que não conseguiram responder aos questionários referentes ao perfil socioeconômico e demográfico, o índice de Barthel e a escala de Lawton e Brody, os quais avaliam a capacidade funcional. A amostra foi composta por 19 idosos, sendo na maioria do sexo feminino (73,7%), entre 70 e 79 anos (47,4%), casados (52,6%), alfabetizados (78,9%). Os dados refletiram a tendência de feminilização da população idosa. Foi observado, também, a prevalência de DCNTs, com predomínio da hipertensão (36,8%). Na análise de capacidade funcional, observou-se que a maioria dos idosos eram independentes (57,9%), de acordo com a escala de Barthel, assim como na escala de Lawton e Brody, os idosos apresentaram independência (52,6%) ou com dependência leve (42,1%). Não foi identificada nenhuma relação positiva entre idade e escolaridade com grau de independência. Observou-se que os idosos possuem um grau de autonomia muito satisfatório, porém não se deve tirar amplas conclusões dos resultados, visto que o número amostral foi pequeno.

O uso de tabaco no Brasil acompanhou a tendência mundial. Passou por séculos de grande intensificação no consumo até começar a sofrer uma redução drástica nos anos 80. No entanto, com o advento do cigarro eletrônico na última década, mesmo tendo sua fabricação e uso proibidos no Brasil pela não comprovação científica das promessas de menos agressivas à saúde, o índice de fumantes voltou a crescer em larga escala. Estudos sobre o tema vêm revelando uma incidência elevada de uso de cigarros eletrônicos dentre os estudantes do curso de medicina. Por esse motivo, o presente trabalho teve como objetivo analisar o uso de cigarro eletrônico entre os acadêmicos de medicina. A metodologia adotada foi uma revisão integrativa da literatura em fontes nacionais e internacionais publicados no período de 2004 a 2021. Como resultado, houve uma análise entre trabalhos realizados em universitários acadêmicos de medicina no Brasil, Paquistão, Arábia Saudita e Jordânia, que indicaram dados preocupantes onde as percepções desses jovens são que os cigarros eletrônicos são menos viciantes e menos prejudiciais à saúde em comparação ao cigarro convencional. Pode-se concluir que poucos estudantes de medicina têm conhecimento sobre cigarros eletrônicos tornando necessárias medidas preventivas e intervenções educacionais para corrigir equívocos sobre o uso desse produto. Também se faz necessária a intensificação de ações do poder público com medidas de fiscalização.

Background

Nepal’s health policy environment and health-care delivery system has changed over the last 25 years, during which it witnessed a significant progress in improving citizens’ access to healthcare services. However, a combination of factors intrinsic to the nation continue to influence health service delivery producing variable health outcomes. Given the nation’s target towards achieving universal health coverage and sustainable development targets, there is a need to review and understand the functioning of Nepal’s health system, its strengths, challenges, and opportunities. The review aims to explore the key health system factors influencing health services and healthcare needs, and forge actionable recommendations for the future.

Methods

The review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for identifying the relevant literature between 2001 and 2023. A total of 300 articles were obtained from the initial search, out of which 42 full text articles were selected for an in-depth review. The literature was analysed to identify the broad themes relevant to Nepal’s health system, and the findings were synthesized narratively under each theme.

Results

The review highlights various factors influencing health services and healthcare needs by describing the historical development of Nepal’s healthcare delivery system, its current scenario, health expenditure, health system challenges and opportunities ahead. The evolution of Nepal’s health system has been both significant and responsive.

Conclusions

The change in the governance structure and adoption of primary healthcare approach present the nation with ample opportunities to further the scope of the nation’s existing health sector initiatives and outcomes.

Background

COVID-19 pandemic curfew made it difficult for families to communicate with their loved ones while hospitalized in the intensive care unit (ICU). A hybrid telephone and video conferencing model (VC) was created as a method of communication. This study aims to assess the satisfaction of critically ill non-COVID-19 patients and their families with VC as a mean of communication during the curfew.

Methods

A prospective observational study was conducted in two academic hospitals. Family visits were replaced by VC during the curfew and visitation restriction. To assess the satisfaction with VC, families were surveyed twice while patients were surveyed once during the ICU admission.

Results

Among 81 family representatives initially surveyed, 26 (32.1%) underwent a follow-up survey. On a scale of 1-10, high general satisfaction was reported by family representatives in the initial and follow-up surveys (8.68 ± 1.66 and 8.31 ± 1.89, respectively). General satisfaction of 9.64 ± 0.67 was reported by the patients who were surveyed during their ICU admission (n=11). Higher patient’s Glasgow Coma Scale at the time of VC and increased number of VC sessions were associated with higher family satisfaction (P=0.001 and P=0.019, respectively). Among family representatives, more than 70% preferred video conferencing over traditional means of communication during the curfew.

Conclusions

Family representatives and their critically ill non-COVID-19 patients were highly satisfied with video conferencing as a mean of communication during the curfew and visiting restriction. Video conferencing offers a great way of communication during pandemics, such as COVID-19.

Overview: This paper provides an overview of disaster management and mitigation strategies in Zambia. Drawing upon a range of academic literature, government reports, and field studies, it examines the various natural and human-induced disasters that Zambia faces, including floods, droughts, disease outbreaks, and industrial accidents. The paper analyzes the country's disaster management framework, highlights key institutions, policies and stakeholders involved in disaster preparedness, response and recovery efforts. Contribution to the Body of Knowledge: Basing on community-based approaches to disaster risk reduction and resilience building, the paper emphasizes the importance of local knowledge and participation in the mitigation of the impacts of disasters. It contributes to the ongoing discourse on enhancing resilience and reducing the impact of disasters on vulnerable populations and environments; and the development of more robust and sustainable disaster management and mitigation strategies that can better protect lives, livelihoods and ecosystems in the face of future disasters. Methods: The study employed a mixed-methods approach, combining qualitative analysis of policy documents and literature reviews with quantitative assessments of food production, consumption patterns, and socioeconomic indicators. Data was collected from various sources, including government reports, academic publications, and international organizations. Data was obtained from respondents by means of interviews, questionnaires and project observation schedules. The sample consisted of two hundred and fifty respondents. Frequency, percentages, tables, graphs and pie-charts were used to analyze the quantitative and qualitative data obtained. Data was then analyzed manually in some cases and also, a combination of software MS Access and MS Excel. Results: Effective disaster management and mitigation require a comprehensive, multi-dimensional approach that integrates preparedness, risk reduction, community engagement, innovation, and global cooperation. By prioritizing resilience-building measures and investing in proactive strategies, societies can mitigate the impact of disasters and foster sustainable development in the face of evolving challenges. Recommendation: governments, organizations, and communities should work together to build more resilient societies and minimize the devastating effects of disasters.
Assessment of post-war groundwater quality in urban areas of Mosul city /Iraq and surrounding areas for drinking and irrigation purposes by using the Canadian Environment Water Quality Index CCME-WQI and Heavy Metal Pollution Index HPI

The negative impact of war acts in the conflict area of the city of Mosul and its surroundings on groundwater quality and thus its use as drinking water, in domestic applications and for irrigation was addressed. Therefore, 8 wells were analyzed from January to September 2022 using the parameters pH, E.C., TDS, % salinity, COD, phosphate, nitrate, sulfate and the heavy metals Cd, Pb, Zn, Cr and Ni, and water quality was evaluated using a mathematical model based on the CCME WQI, the HPI and present salinity. Due to salinity, 6 of the 8 wells were moderately suitable for irrigation and 2 wells were difficult in use. According to the CCME WQI criteria, 4 wells were highly and 3 wells were moderately contaminated for drinking water supply and domestic use, and therefore unusable or limited usable, while 3 wells were unusable and 2 wells were moderately usable for irrigation purposes. For irrigation, only one well showed low and 2 wells showed marginal contamination. The HIP revealed good quality of 3 wells, poor quality of 2 wells and unsuitability of 3 wells (drinking water/ domestic use) or very poor quality (irrigation), respectively. According to all approaches, the wells located in the conflict area consistently showed poor water quality. Thus, war had a significant negative impact on groundwater quality in the conflict area, as the surface-near wells located here showed comparatively high levels of contaminations and heavy metals due to the infiltration of contaminated surface water, damaged sewage networks and infiltration of rainwater after passing through highly polluted soils. Cadmium, followed by lead, were the dominant water contaminants, which is why caution is advised before using this well water.
