The article addresses the study by Kainth et al on the use of paracetamol for treating patent ductus arteriosus (PDA) in preterm neonates, noting several observations. Topics include the impact of changes in fluid management protocols on PDA incidence and outcomes, the definition and clinical features of hemodynamically significant PDA (hsPDA), and the need for a comprehensive assessment of paracetamol's potential side effects.

Engineering properties of soils coated with naturally occurring or artificially manufactured particles can significantly differ from those of uncoated soils. This study aims at evaluating the effect of iron oxide coatings on the thermal conductivity of silica sands. Laboratory thermal needle probe tests were conducted on uncoated, goethite coated and hematite coated Ottawa 20/30 and Ottawa 100/200 sands. Test results demonstrated that the thermal conductivity (k) of all tested materials increases with increasing applied vertical stress, and the k of hematite coated sands was greater than that of uncoated sands under the similar relative density. However, the measured k of both uncoated and coated sands is a single function of porosity regardless of applied stress level, reflecting the limited effect of applied stress and iron oxide mineral coating on the k of tested materials. Simple resistances in series model was employed to explain the observed test results, and the results of this study was compared with k of previous studies on uncoated natural soils.

The automotive industry is facing a crucial time. The transformation from internal combustion engines to new electrical technologies requires enormous investment, and hence the IC engines are likely to serve as a means of transportation for the coming decades. The search for sustainable green alternative fuel and operating parameter optimization is a current feasible solution and is a critical issue among the scientific community. Engine experiments are complicated, costly, and time-consuming, especially when the global economy is drastically down due to the COVID-19 pandemic and putting the limitation of social distancing. Industries are looking for proven computational solutions to address these issues. Recently, artificial neural network has been proven beneficial in several areas of engineering to reduce the time and experimentation cost. The IC engine is one of them. ANN has been used to predict and analyze different characteristics such as performance, combustion, and emissions of the IC engine to save time and energy. The complex nature of ANN may lead to computation time, energy, and space. Recent studies are centered on changing the network topology, deep learning, and design of ANN to get the highest performance. The present study summarizes the application of ANN to predict and optimize the complicated characteristics of various types of engines with different fuels. The study aims to investigate the network topologies adopted to design the model and thereafter statistical evaluation of the developed ANN models. A comparison of the ANN model with other prediction models is also presented. [ABSTRACT FROM AUTHOR]

A recent article published in Indian Pediatrics examines the impact of temperature variation on neonatal dehydration in Mysuru, India. The study, which has a small sample size of 55 neonates, found that seasonal temperatures can affect dehydration levels. However, the study is limited in scope and does not provide a broader contextual analysis. The article suggests that a multicenter study across India could provide a better understanding of temperature variations and potentially lead to the development of protocols or standards of care to minimize neonatal morbidity.

Objective: To describe clinical features and early neurological outcomes in neonatal Chikungunya.Methods: Clinical, pathological and radiological details of neonates with acute encephalitic features and typical rash, later diagnosed as Chikungunya, are presented. Neurodevelopmental evaluation and imaging was done at discharge/three months.Results: Abnormal neurological examination with fever was typical presentation in all 13 babies with/without seizures/peri-oral rashes; 12 had persistent neurological abnormalities at discharge. A follow-up at three months revealed continued neurodevelopmental deficits. Neuroimaging abnormalities were seen in eight out of ten cases.Conclusions: Perinatal Chikungunya should be considered in neonates presenting within first week with fever, encephalopathy and perioral rashes with/without seizures with history of maternal Chikungunya within last week before delivery.
