A “near miss" congenital eventration of the right hemidiaphragm in a neonate: a case report

Focal eventration involving the posterior segment of the hemidiaphragm is a rare congenital anomaly. We report of a 10-day-old infant who presented with significant respiratory insufficiency and failure to show any responses to standard treatment. The diagnosis of focal eventration of the diaphragm was not anticipated until ultrasonographic examination revealed the defect. Diaphragmatic plication resulted in complete resolution of symptoms. A high level clinical awareness is crucial as a relatively simple surgical procedure could avert long term life-threatening complications

Flexible Nodes Exclusion and Inclusion Capability Migration Model for Hybrid Software-Defined Network

—Software-defined networking (SDN) is a popular network technology that enables flexible programmed network setup for optimizing network performance. However, the high cost of migrating existing devices to SDN leads to slow deployment particularly for large networks with thousands or more nodes. There are research works proposing methods for SDN migration under the total cost and budget but they lack the flexibility for network operator to set the specific budget in each time step for migration. Also, no research proposed a method for migrating a group of nodes that have a close relationship. Lastly, existing research also do not allow to set the node to be excluded from migration based on current network operation requirements. Therefore, we proposed a new hybrid software-defined network (Hybrid SDN) migration model that uses integer linear programming (ILP) formulation for calculating the migration nodes based on the user’s input dataset such as the number of nodes, the cost of nodes, the number of time step, the budget for each time step, the number of migration in certain time step, the nodes for U-pairs (a group of nodes that must be migrated together), and the nodes to be excluded from migration. This new model supports practical SDN migration that allows a group of nodes to be migrated together under flexible budget at each time step

Variations in medical practice of retinopathy of prematurity among 8 Asian countries from an international survey

Abstract Advances in perinatal care have led to the increased survival of preterm infants with subsequent neonatal morbidities, such as retinopathy of prematurity (ROP). This study aims to compare the differences of neonatal healthcare systems, resources, and clinical practice concerning ROP in Asia with review of current literature. An on-line survey at the institutional level was sent to the directors of 336 neonatal intensive care units (NICU) in 8 collaborating national neonatal networks through the Asian Neonatal Network Collaboration (AsianNeo). ROP screening was performed in infants born at < 34 weeks in Indonesia and Japan. In South Korea, Malaysia, and Taiwan, most screened for ROP in infants born at < 32 weeks. In all networks, majority of NICUs conducted ROP screening to infants with birth weight < 1500 g. In most NICU’s in-hospital ophthalmologists performed indirect ophthalmoscopy and some were supplemented with digital imaging. Both laser photocoagulation and anti-vascular endothelial growth factor injection are performed for treatment and, vitreous surgeries are conducted less frequently in all countries. Despite limited information collected by the survey, this first study to compare ROP practices implemented in eight Asian countries through AsianNeo will enable an understanding of the differences and facilitate quality improvement by sharing better practices

Contemporary fluid management, humidity, and patent ductus arteriosus management strategy for premature infants among 336 hospitals in Asia

ObjectivesThe management of patent ductus arteriosus (PDA) is a critical concern in premature infants, and different hospitals may have varying treatment policies, fluid management strategies, and incubator humidity. The Asian Neonatal Network Collaboration (AsianNeo) collected data on prematurity care details from hospitals across Asian countries. The aim of this study was to provide a survey of the current practices in the management of PDA in premature infants in Asian countries.MethodsAsianNeo performed a cross-sectional international questionnaire survey in 2022 to assess the human and physical resources of hospitals and clinical management of very preterm infants. The survey covered various aspects of hospitals resources and clinical management, and data were collected from 337 hospitals across Asia. The data collected were used to compare hospitals resources and clinical management of preterm infants between areas and economic status.ResultsThe policy of PDA management for preterm infants varied across Asian countries in AsianNeo. Hospitals in Northeast Asia were more likely to perform PDA ligation (p &lt; 0.001) than hospitals in Southeast Asia. Hospitals in Northeast Asia had stricter fluid restrictions in the first 24 h after birth for infants born at &lt;29 weeks gestation (p &lt; 0.001) and on day 14 after birth for infants born at &lt;29 weeks gestation (p &lt; 0.001) compared to hospitals in Southeast Asia. Hospitals in Northeast Asia also had a more humidified environment for infants born between 24 weeks gestation and 25 weeks gestation in the first 72 h after birth (p &lt; 0.001). A logistic regression model predicted that hospitals were more likely to perform PDA ligation for PDA when the hospitals had a stricter fluid planning on day 14 after birth [Odds ratio (OR) of 1.70, p = 0.048], more incubator humidity settings (&lt;80% vs. 80%–89%, OR of 3.35, p = 0.012 and &lt;80% vs. 90%–100%, OR of 5.31, p &lt; 0.001).ConclusionsIn advanced economies and Northeast Asia, neonatologists tend to adopt a more conservative approach towards fluid management, maintain higher incubator humidity settings and inclined to perform surgical ligation for PDA
