Care during the COVID-19 pandemic hinges upon existence of fast, safe, and highly sensitive diagnostic tools. Considering significant practical advantages lung ultrasound (LUS) over other imaging techniques, but difficulties for doctors in pattern recognition, we aim to leverage machine learning toward guiding diagnosis from LUS. We release largest publicly available LUS dataset consisting 202 ...

Lung ultrasound (LUS) allows for the detection of a series manifestations COVID-19, such as B-lines and consolidations. The objective this work was to study inter-rater reliability (IRR) when detecting signs associated with COVID-19 in LUS, well performance test longitudinal or transverse orientation. Thirty-three physicians advanced experience LUS independently evaluated videos previously acqu...

Novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a pandemic of epic proportions and global response to prepare health systems worldwide is utmost importance. In addition its cost-effectiveness in resources-limited setting, lung ultrasound (LUS) emerged as rapid noninvasive imaging tool for the diagnosis COVID-19 infected patients. Concerns surrounding LUS include di...

Background: Bronchiolitis obliterans syndrome (BOS) and restricted allograft (RAS) are two distinct phenotypes of chronic lung dysfunction (CLAD) in transplant (LTx) recipients.  Contrary to BOS, RAS can radiologically present with a pleuroparenchymal fibroelastosis (PPFE) pattern. This study investigates ultrasound (LUS) identify potential surrogate markers radiological PPFE patter...

BACKGROUND The availability of ultra-miniaturized pocket ultrasound devices (PUD) adds diagnostic power to the clinical examination. Information on accuracy of ultrasound with handheld units in immediate differential diagnosis in emergency department (ED) is poor. The aim of this study is to test the usefulness and accuracy of lung ultrasound (LUS) alone or combined with ultrasound of the heart...

This paper provides an overview the current trends and the policy issues for e-learning implementation in Libyan universities LUs.; where is present a sample model to comparative between two questionnaires in 2009& 2013; as a technique to evolution the e-learning policy implementation process in LUs. The paper emphasizes that in spite of the drawbacks faced by most HE institutions, some have ma...

BACKGROUND The rate of cesarean delivery has significantly increased in China in the last decade. Women with prior cesarean history tend to have a higher risk of uterine rupture during termination of the pregnancy in mid-trimester than those without such a history. The aim of our study was to evaluate the influences of the potential risk factors on uterine rupture in women with prior cesarean. ...

Transient tachypnea of the newborn (TTN) is one of the most common causes of perinatal dyspnea and is traditionally diagnosed by chest x-ray. This study aimed to explore the diagnostic value of lung ultrasonography (LUS) for TTN as well as differentiate it from respiratory distress syndrome (RDS) by using LUS. From January 2013 to February 2014, 60 infants who were diagnosed with TTN based on m...
