Authors: Zhao Jinghan , Yan Peihua , Qureshi Aizaz , Chiang Yi Wai
Published: August 2023

Nanotechnology has been rapidly developing in the past decade, and metal nanomaterials have shown promising improvement in microbial control. Metal nanoparticles have been applied in medical settings for adequate disease spread control and to overcome the challenges of multidrug-resistant microorganisms. Recently, the demand for safe water supply has increased, requiring higher sanitation of the water treatment technology as well as being environmentally sustainable. However, the employed water disinfection technologies cannot meet the elevated demand due to limitations including chemical byproducts, immobility, energy consumption, etc. Metal nanomaterials are considered to be an alternative disinfection technology considering their high efficiency, mobility, and stability. A significant amount of research has been carried out on enhancing the antimicrobial efficiency of metal nanomaterials and determining the underlying antimicrobial mechanisms. This paper provides an overview of emerging metal nanomaterials development, including the synthesis method, material characteristics, disinfection performance, environmental factors, potential mechanism, limitations, and future opportunities in the water disinfection process.

Published: August 2023

Human beings are frequently exposed to a mixture of chemical pollutants through the ingestion of contaminated drinking water. The present study aimed to assess the ecological and human health risks associated with the contamination of cyanotoxins and heavy metals in a drinking water supply reservoir, the Tri An Reservoir (TAR), in Vietnam. Results demonstrated that the concentrations of individual heavy metals varied in the following order: iron (Fe) > lead (Pb) > arsenic (As) > zinc (Zn). Although the ecological potential risk of heavy metals was low during the study period, the concentration of Fe sometimes exceeded the Vietnamese standard for drinking water. Toxic cyanobacteria and microcystins (MCs) frequently occurred in the TAR with the highest density of 198.7 × 103 cells/mL and 7.8 μg/L, respectively, indicating a high risk of health impacts to humans. The results of the study indicate that exposure to heavy metals does not pose any non-carcinogenic health risks for both adults and children. However, the contamination of MCs in the surface water posed a serious disease enhancement to both adults and children through direct ingestion and dermal absorption.

Published: August 2023

Accurate Crop Evapotranspiration (ETc) estimation is crucial for understanding hydrological and agrometeorological processes, yet it's challenged by multiple parameters, data variations, and lack of continuity. These limitations restrict numerical methods application. To address this, the study aims to develop and assess ML models for daily maize ETc in semi-arid areas, utilizing varied weather inputs. Five ML models viz., Category Boosting (CB), Linear Regression (LR), Support Vector Machine (SVM), Artificial Neural Network (ANN), and Stochastic Gradient Descent (SGD) were developed and validated for the ICAR-IARI, New Delhi, Research Station. Penman-Monteith (PM) model estimated ETc values are used as the standard for comparing the performance of the ML model values. Results revealed that the SVM model achieved the highest coefficient of determination (R2) among all models, with a value of 0.987. Furthermore, the SVM model exhibited the lowest model errors (MAE = 0.121 mm day−1, RMSE = 0.172 mm day−1, and MAPE = 4.37%) compared to other models. The ANN model also demonstrated promising results, comparable to the SVM model. Notably, the wind speed parameter was found most influential input parameter. In conclusion, SVM or ANN could be considered reliable alternative methods for the accurate estimation of kharif maize crop ETc in the semi-arid climate.

Authors: AlShehhi Ruqaya Ahmed , Ahmed Fatma Refaat , Yateem Nabeel AL , Selgado Arnel
Published: August 2023

Background:

The patient experience is an essential dimension of patient satisfaction. An interesting initiative that has been reported internationally is the Proactive Patient Rounding intervention (PPR), a process of proactive, purposeful, directed communication and evaluation of patient needs. It entails visiting and monitoring patients at an interval of one to two hours. PPR implementation has not been evaluated in the UAE, or in the GCC counties.

Objective:

This study aimed to assess the effect of PPR implementation on patient satisfaction levels.

Methods:

Post-test quasi-experimental non-equivalent design was used to conduct this study, with a convenience sample of 60 participants from surgical units (comprising 30 control and 30 experimental subjects). The participants were requested to fill out the survey on the 3rd day of admission

Results:

The study revealed positive increases in patient satisfaction scores. as the experimental group scores were slightly higher than the control group for most of the satisfaction statements and for the overall satisfaction score (experimental m = 4.6, control m = 4.41). However, the independent t-test indicated that this difference was not statistically significant (sig. 0.161).

This study is useful in directing attention to the influence of PPR on several aspects like patient satisfaction, reduce pressure ulcers, and decrease call light.

Conclusion:

PPR interventions are a practical approach for addressing the needs of hospitalized patients, and nurse managers should monitor its implementation to get purposeful patients feedback.

Published: August 2023

The COVID-19 pandemic exacerbated gender inequity in medicine, with women physicians reporting greater household responsibilities than their men counterparts and steeper barriers to career advancement. The pandemic highlighted the systemic assumptions and challenges faced by women physicians, which we anticipate is also true in our field of oncology. Prior literature suggests that women physicians were tasked with increased personal and professional responsibilities without compensation for their additional work, as well as derailments in career progression and significant burnout. Our aims are to highlight areas of opportunity to optimize the workplace experience of the oncology workforce and to invest in the professional well-being and sustainability of women oncologists as a step toward global workplace equity and future pandemic preparedness.

Authors: Tian Huichuan , Zhang Yao , Ren Jiajun , Wang Chaoran , Mou Ruiyu , Li Xiaojiang , Jia Yingjie
Published: August 2023

BACKGROUND

Among the common malignant tumors in men worldwide, the incidence of prostate cancer ranks second to lung cancer. This disease will bring an economic burden to patients and their families and can reduce the quality of life of patients. Researchers have conducted numerous clinical trials on the efficacy and safety of different interventions in the treatment of prostate cancer with traditional Chinese medicine (TCM) combined with standard treatment regimens. However, the currently published clinical trials exhibit inconsistent and irregular reporting of outcome measures.

OBJECTIVE

The objective of this paper is to emphasize the need for a core outcome set (COS) to facilitate future prostate cancer research, aiming to improve the quality of trials and generate high-quality evidence.

METHODS

This mixed methods project has three phases, as follows: (1) a scoping review of the literature to identify outcomes that have been reported in clinical trials and systematic reviews of interventions involving TCM for the treatment of prostate cancer as well as a qualitative component using interviews to obtain the views of patients with prostate cancer, their families, and their caregivers who have a history of TCM treatment; (2) a Delphi survey among stakeholders to prioritize the core outcomes—Participants will include traditional Chinese and Western medicine clinicians in prostate cancer–related directions, nurses, and methodology experts who will participate in 2 rounds of the Delphi method expert consultation to score each outcome in the list of outcome indicators; and (3) a face-to-face consensus meeting to discuss and agree on the final COS for the application of TCM in the treatment of prostate cancer.

RESULTS

The protocol has been registered in PROSPERO (CRD42022356184) before the start of the review process, and we will initiate the review on August 1, 2023; results should be expected by September 1, 2023. The Delphi survey among stakeholders is expected to start in October 2023.

CONCLUSIONS

The development of a core outcome set for assessing clinical safety outcomes of prostate cancer in clinical trials of TCM will provide a significant first step to assist Chinese doctors, researchers, and policy makers.

Eating Habits and Lifestyle Factors Related to Childhood Obesity Among Children Aged 5-6 Years: Cluster Analysis of Panel Survey Data in Korea (Preprint)
Authors: Lim Heemoon , Lee Hyejung
Published: August 2023

BACKGROUND

Childhood obesity has emerged as a major health issue due to the rapid growth in the prevalence of obesity among young children worldwide. Establishing healthy eating habits and lifestyles in early childhood may help children gain appropriate weight and further improve their health outcomes later in life.

OBJECTIVE

This study aims to classify clusters of young children according to their eating habits and identify the features of each cluster as they relate to childhood obesity.

METHODS

A total of 1280 children were selected from the Panel Study on Korean Children. Data on their eating habits (eating speed, mealtime regularity, consistency of food amount, and balanced eating), sleep hours per day, outdoor activity hours per day, and BMI were obtained. We performed a cluster analysis on the children’s eating habits using k-means methods. We conducted ANOVA and chi-square analyses to identify differences in the children’s BMI, sleep hours, physical activity, and the characteristics of their parents and family by cluster.

RESULTS

At both ages (ages 5 and 6 years), we identified 4 clusters based on the children’s eating habits. Cluster 1 was characterized by a fast eating speed (fast eaters); cluster 2 by a slow eating speed (slow eaters); cluster 3 by irregular eating habits (poor eaters); and cluster 4 by a balanced diet, regular mealtimes, and consistent food amounts (healthy eaters). Slow eaters tended to have the lowest BMI (P<.001), and a low proportion had overweight and obesity at the age of 5 years (P=.03) and 1 year later (P=.005). There was a significant difference in sleep time (P=.01) and mother’s education level (P=.03) at the age of 5 years. Moreover, there was a significant difference in sleep time (P=.03) and the father’s education level (P=.02) at the age of 6 years.

CONCLUSIONS

Efforts to establish healthy eating habits in early childhood may contribute to the prevention of obesity in children. Specifically, providing dietary guidance on a child’s eating speed can help prevent childhood obesity. This research suggests that lifestyle modification could be a viable target to decrease the risk of childhood obesity and promote the development of healthy children. Additionally, we propose that future studies examine long-term changes in obesity resulting from lifestyle modifications in children from families with low educational levels.

Authors: Llanos Reynoso Luis Felipe
Published: August 2023

El home office aseguró la continuidad de muchas empresas ante la crisis de la pandemia. Sin embargo, se sabe poco sobre las implicaciones de una transición forzada del trabajo en la oficina al trabajo a distancia. El interés de la investigación es medir la autoeficacia y el engagement de los trabajadores antes y después del confinamiento obligatorio, e identificar si estas características disminuyen, y en su caso, determinar si su relación causal se sigue manteniendo. Se elaboró un diseño de investigación empírico, cuantitativo, transversal y longitudinal, a partir de los datos de 216 trabajadores que migraron su trabajo, de su oficina a su casas, y con la ayuda de un modelo de ecuaciones estructurales, se determinó que la autoeficacia y el engagement que manifestaron tener antes de la pandemia, trabajando en oficina, se pierden ahora trabajando en casa, pero su relación causal continua presentándose. Esto implica que las empresas requieren replantear sus esquemas de entrenamiento y de acciones orientadas a mejor la autoeficacia y por lo tanto el engagement de sus trabajadores, si quieren seguir trabajando desde casa.

Antropônimos esporádicos no português do Brasil: o caso das construções [MC X]N (Nonce anthroponyms in Brazilian portuguese: the [MC X]N constructions case)
Authors: Simões Neto Natival Almeida , Rodrigues Letícia Santos
Published: August 2023

Neste trabalho, foram analisados antropônimos esporádicos a partir da formação [MC X]N no português brasileiro, a exemplo de MC 50 reais, MC Cuscuz, MC Ortobom, MC Detran e MC Cidade Alerta. Tais nomes foram empregados por usuários de redes sociais da internet e se referem a personalidades famosas, normalmente de forma pejorativa. Essas realizações de caráter esporádico, ainda que passíveis de sistematização, parecem não se encaixar de maneira apropriada nas categorias de antropônimos propostas por Leite de Vasconcelos (1928), Amaral (2011), Araujo (2013), Amaral e Seide (2020) e Soledade (2022). Nesse sentido, propôs-se, neste artigo, a categoria de “nomes esporádicos”, que foi analisada não só no que toca às práticas de nomeação, mas também quanto à configuração morfológica e à motivação semântica. Para esses dois últimos aspectos, aplicaram-se conceitos da Morfologia Construcional e da Semântica Cognitiva.

Authors: Procópio Eliabe , Silva Patrícia Lima da
Published: August 2023

O presente trabalho se situa nos estudos da morfologia lexical, mais especificamente no campo da composição vocabular, e tem por objetivo analisar os cruzamentos vocabulares (CVs) com a palavra ‘Roraima’, com atenção aos aspectos morfofonológicos, gráficos e discursivos. A metodologia consiste na identificação e na coleta do corpus (57 palavras), atividades realizadas principalmente de forma virtual e complementada pela observação ao transitar por Boa Vista-RR.  A conclusão é que ‘Roraima’ é uma base lexical produtiva para a formação de novos topônimos comerciais e institucionais em Boa Vista-RR, para os quais ‘Rorai-’, ‘-raima’ ou ‘-aima’ são combinados com outras palavras. O CV implica também outros processos morfológicos e fonológicos, como a sigla, a monotongação e o uso de formas presas e sufixoides. O resultado desses cruzamentos funciona como uma marca identitária e sociolinguística do falar roraimense na esfera comercial.
Capturing mesoscale structures in multiphase CFD simulations
Authors: Ganesh Swathi , Kumar Balivada , Goyal Himanshu
Published: August 2023

Multiphase reactors’ performance depends on the mesoscale structures
formed due to multiphase hydrodynamics. Examples of mesoscale structures
include gas bubbles in a fluidized bed and particle clusters in a riser.
Experimental investigation of these mesoscale structures is challenging
and expensive. To this end, Computational Fluid Dynamics (CFD)
simulations are extensively employed; however, post-processing CFD data
to capture mesoscale structures is challenging. This work develops a
DBSCAN-based methodology to capture and characterize mesoscale
structures from multiphase CFD simulation data. DBSCAN is an
unsupervised machine-learning algorithm, which requires the value of two
hyperparameters. A simple technique to calculate these hyperparameters
is provided and the performance of DBSCAN is assessed on CFD-DEM
simulations of bubbling fluidized beds and particle clustering. We
demonstrate the computational complexity of DBSCAN to be Ο(n log n),
lower than the existing techniques, by testing its scalability on highly
resolved grids (up to 100 million grid points).

based on extended homogeneous polynomial Lyapunov function (EHPLF) to
regulate heading for the superior performance on the rapidity, accuracy
and robustness. Firstly, a NPV model of heading error is established to
design a general form of a state feedback controller with a robust H ∞
performance. Secondly, a Lyapunov matrix with full states and varying
parameter is constructed to derive the robust H ∞ global exponential
stability conditions by Euler’s homogeneity relation for the NPV system,
known as the EHPLF stability conditions. Thirdly, since the EHPLF
stability conditions consist of a set of nonlinear coupled inequalities
that cannot be directly solved by sum of squares (SOS) toolboxes, they
are decoupled with matrix transformations to obtain the EHPLF-SOS
stability conditions, which is solved for the parameters of the state
feedback controller. Finally, the simulation results indicate that EHPLF
method exhibits a superior performance on dynamic, steady-state and
robustness.

Di(2-ethylhexyl) terephthalate (DEHTP) is a substitutive plasticizer
with various industrial applications. However, its wide occurrence in
environmental matrices and human tissues is urging concerns on its
toxicities. Presently, the effects of DEHTP on the fitness of
Caenorhabditis elegans were explored with a consecutive exposure
from F1 to F4 generations. The fitness was represented by reproduction,
lifespan and behavior. Effects of DEHTP on reproduction showed an
oscillation pattern with alteration from stimulation to inhibition and
backwards. Influences of DEHTP on reproduction and lifespan showed
trade-off relationships. Regarding behavior, DEHTP inhibited satiety
quiescence duration, body bending and head swing, while stimulated
reverse and Omega turns. At the biochemical level, DEHTP disturbed the
lipid metabolites and lipid metabolism enzymes. Moreover, positive
correlations were found between the effects on reproduction and with
those on fatty acid synthase (FAS) and acyl-CoA (FA-CoA). DEHTP also
disturbed the neural regulations including neural transmitters and the
expressions of related genes. Out of expectation, the effects on neural
regulations were positively correlated with those on lipid metabolism,
but not with locomotion behavior. Hierarchical clustering analysis (HCA)
results also indicated oscillatory changes underlying multi-generational
effects of DEHTP, e.g., serotonin was more connected with other neural
regulations than other indicators in F1 and F3, while it was more
connected with behavior than others in F2 and F4.
Influence of gravity and mechanical strip load on a micropolar thermoelastic theory with two-temperatures
Authors: Othman Mohamed , Abd-Elaziz Elsayed
Published: August 2023

A new model of two-temperatures for a generalized micropolar
thermo-elastic medium has been established in this paper. A medium is
affected by a gravitational field and two types of mechanical strip load
(continuous load and impact load). The technique called Laplace Fourier
transform has been utilized to obtain the analytical expressions of
variables under deliberation. The numerical and graphical illustration
of the results has been carried out to indicate the differences among
one temperature model, the classical dual-temperature model, and the
hyperbolic dual-temperature model upon the Lord and Shulman theory,
also, in the case of Coupled Theory (CT) and Lord and Shulman theory
(L-S), we discussed the effect of the gravitational field and mechanical
strip load. The most significant points are highlighted. The current
investigation has led us to deduce some particular cases of special
interest. When it comes to heat conduction’s new general model then this
study will be extremely beneficial in developing a better understanding
of the ingrained features.

Background India, in general, has health inequities. In terms
of reproductive health (RH) different States vary. This study
investigates the disparities in RH and the underlying causes in various
Indian states. Based on a large-scale population-based, nationally
representative dataset, the current study aims to track the changes
between NFHS-IV and NFHS-V in the status of RH and examine the factors
contributing to it in various regions of India for women aged 15 to 49
years in 29 states (NFHS-IV and NFHS-V). Methods According to
claims, in India’s States’ reproductive health status is gauged by the
reproductive health index (RHI). The total fertility rate (TFR), infant
mortality rate (IMR), childbirth order, mother-and-child delivery care,
and female educational attainment rate are the five variables that make
up this composite index. Results In NFHS-IV, India’s RHI score
was 61.5, and in NFHS-V, it was 67.8. Although there has been progress
in RHI, it has not been at the level that was anticipated. Eleven
NFHS-IV states and eight NFHS-V states have index values below India’s
RHI threshold. Conclusion In order to move the situation
forward, desires for using contraception should be given more weight.
The level of educational achievement of women should also be raised, as
should their passionate participation in economic activity. By doing so,
they will be able to make more independent decisions and lower their
high birth and infant mortality rates.

Published: August 2023

Lignite and coal waste used as feed fuels in thermal power plants (TPPs) and semi-industrial fluidized bed boiler (FBB), as well as their representative fly ashes (FAs), were examined. Fly ashes were compared employing anions and cations content in correspondent water extracts, trace elements and polycyclic aromatic hydrocarbon concentrations, as well as health risk assessments of substances known to be of concern for public health. Fluoride and sulfate contents in water extracted FAs are far below the legislation limits for waste, classifying all investigated FAs as non-hazardous. Among investigated trace elements, Cd content is the lowest, while Mn content is the highest. The highest enrichment ratios are noticed for As, Pb, Hg, Cu, V and Cr. The results indicate that total PAHs content is elevated in FA from the combustion of coal waste (AFB), with fluoranthene prevailing. The cancer risk of As and the non-cancer risk of As and Ni in some FAs surpass their respective permissible limits. The incremental lifetime cancer risk of an adult population indicates a potential PAHs risk in AFB, whereas all other fly ashes are within safe limits.

OBJECTIVE

The aim of this study was to determine dose-response associations, including the minimal effective level, between leisure-time physical activity and risk of incident neuropathy, nephropathy, and retinopathy.

RESEARCH DESIGN AND METHODS

This cohort study included 18,092 individuals with type 2 diabetes from the UK Biobank. Self-reported leisure-time physical activity was converted into MET-hours per week. Participants were categorized into no physical activity (0 MET-h/week), below recommendations (0–7.49 MET-h/week), at recommendations (7.5–14.9 MET-h/week), and above recommendations (≥15 MET-h/week). Microvascular complications were identified from hospital inpatient records using diagnosis codes. We used Cox proportional hazards regression analysis to calculate adjusted hazard ratios (aHRs) and restricted cubic splines to identify the minimal effective level of physical activity.

RESULTS

During a median follow-up of 12.1 years, 672 individuals (3.7%) were diagnosed with neuropathy, 1,839 (10.2%) with nephropathy, and 2,099 (11.7%) with retinopathy. Any level of physical activity was associated with a lower risk of neuropathy and nephropathy but not retinopathy. Compared with those reporting no physical activity, the aHR of neuropathy was 0.71 (95% CI 0.53, 0.90) below recommendations, 0.73 (0.56, 0.96) at recommendations, and 0.67 (0.52, 0.87) above recommendations. Corresponding aHRs for nephropathy were 0.79 (0.68, 0.92), 0.80 (0.67, 0.95), and 0.80 (0.68, 0.95). The association with retinopathy was weaker, with aHRs of 0.91 (0.78, 1.06), 0.91 (0.77, 1.08), and 0.98 (0.84, 1.15), respectively.

CONCLUSIONS

Any level of leisure-time physical activity was associated with a lower risk of neuropathy and nephropathy but not retinopathy in individuals with type 2 diabetes. For both neuropathy and nephropathy, the minimal effective physical activity level may correspond to <1.5 h of walking per week.
