Speckle tracking echocardiography (STE) is a promising tool for assessment of myocardial function. The aim of this study is to evaluate the global longitudinal strain (GLS) using 2D-STE in healthy neonates to establish normal reference ranges. Method: it is a retrospective study through an analysis of transthoracic echocardiogram of normal healthy neonates. We enrolled all neonates in our institution from 1 January 2021 to 28 February 2021. 2-D STE was used to assess left ventricular global longitudinal strain from the apical views. Results: 185 neonates were enrolled. Mean value for left ventricle GLS (%) was -19.9 ± 1.2, GLS-derived ejection fraction (%) was 60.0 ± 2.7; while the left ventricle ejection fraction by biplane Simpson’s method (%) was 61.0 ± 3. There is a good positive correlation between the Left...
Right ventricular (RV) volume overload occurs in patients with significant atrial septal defect (... more Right ventricular (RV) volume overload occurs in patients with significant atrial septal defect (ASD II) shunts, which can impair left ventricle (LV) filling, thus decreasing LV indices. However, after ASD II closure, the left ventricle regains near normal dimensions. The purpose of this study was to compare the long-term outcomes of LV reverse remodeling between device and surgical closure. We retrospectively reviewed the echocardiographic data of 222 patients with isolated ASD II who underwent surgical (95 patients) or device closure (127 patients) between January 2012 and December 2017. The ASD II was significantly larger in the surgical closure group (p < 0.001.) leading to a higher degree of paradoxical interventricular septal (IVS) movement. In contrast, the LV volume was larger in the device closure group (p < 0.001). After a median follow-up period of 19.5 months, the maximum LV systolic and diastolic volumes were reached at 1 year in the device closure group and 2 years in the surgical closure group. IVS motion normalized in 91% of the device closure group compared to 57% of the surgical closure group (p = < 0.001). There was significant improvement in left ventricular indices and IVS motion after ASD II closure in both groups but more favorable in patients after device closure.

Cloud Computing provides a lot of prospects to users/organizations; it also exposes security concerns which leads to low adoption, implementation and usage. Therefore, the study will examine standard ways of improving cloud computing adoption, implementation and usage by proposing and developing a security model using a design methodology that will ensure a secured Cloud Computing and also identify areas where future regularization could be operational.

Users can also share the software and other resources on demand. It allows the users to do computing services without the need for them to buy and set up IT infrastructure. The services that are delivered by cloud computing may be accessible worldwide, at low or no cost and based on-demand by users. Cloud computing also delivers different services and deployment models; it also offers some security measures for various services and deployment models. Cloud computing and technology provide individual client/users and organizations with different functionalities to store and process their data in third-party (cloud providers) data centers.

Cloud computing makes use of internet technology as a means of delivering resources for use and has classifications such as Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a service (IaaS) in accordance to the classification of service delivered which will not necessarily be imaginable without the internet for access globally. Also, the process of storing and accessing data and programs over the Internet as an alternative of computer hard drive which makes use of Internet and as representation for the Internet.
