Although there is limited evidence that antepartum testing decreases the risk for fetal death in low-risk pregnancies, women with high-risk factors for stillbirth should undergo antenatal fetal surveillance. The strongest evidence supporting antepartum testing pertains to pregnancies complicated by intrauterine fetal growth restriction secondary to uteroplacental insufficiency. The main ultrasound-based modalities to determine fetal health are the biophysical profile, modified biophysical profile, and duplex Doppler velocimetry...

BACKGROUND: Three-dimensional contrast-enhanced ultrasound (3D-CEUS) is a novel technology allowing surgeons to view duplex ultrasound images in three dimensions with ultrasound contrast highlighting blood flow in endoleaks after endovascular aneurysm repair (EVAR). It potentially reduces the need for computed tomography angiography (CTA) and catheter angiography. This study compares 3D-CEUS with both CTA and the final vascular multidisciplinary team (MDT) diagnosis using all available imaging...

BACKGROUND: Tick-borne diseases caused by Anaplasma species put serious constraints on the health and production of domestic cattle in tropical and sub-tropical regions. After recovering from a primary infection, cattle typically become persistent carriers of pathogens and play a critical role in the epidemiology of the disease, acting as reservoirs of the Anaplasma spp. METHODS: In this study a duplex PCR assay was used for the simultaneous detection of Anaplasma marginale and Anaplasma phagocytophilum in cattle using two primer pairs targeting msp4 and msp2 genes, respectively...

OBJECTIVE/BACKGROUND: Surveillance after endovascular aortic aneurysm repair (EVAR) is mandatory and computed tomography angiography (CTA) is considered the standard imaging modality, although patients are exposed to ionizing radiation and nephrotoxic contrast medium. The primary aim of this study was to determine the diagnostic efficacy of duplex ultrasound (DUS) and contrast enhanced ultrasound (CEUS) using CTA as the gold standard. The secondary aim was to determine the clinical consequences of endoleaks missed by DUS and CEUS, or CTA...

African horse sickness (AHS) and equine infectious anemia (EIA) are both notifiable equid specific diseases that may present similar clinical signs. Considering the increased global movement of horses and equine products over the past decades, together with the socio-economic impact of previous AHS and EIA outbreaks, there is a clear demand for an early discrimination and a strict control of their transmission between enzootic and AHS/EIA-free regions. Currently, the individual control and prevention of AHS or EIA relies on a series of measures, including the restriction of animal movements, vector control, and the use of several laboratory techniques for viral identification, amongst others...

OBJECTIVE: The influence of endovascular aneurysm repair (EVAR) on renal function is of high concern. The question whether stent graft fixation type plays a significant role in renal outcome after EVAR is still debated. However, other factors, such as repeated contrast medium exposure, should also be considered. METHODS: We performed a two-center, stratified-cohort case control study to evaluate the influence of last-generation abdominal endografts with suprarenal (SR) vs infrarenal (IR) fixation on renal function...

Bartonella henselae and Bartonella quintana are the major etiological agents of infective endocarditis, which pose a serious threat to human health. To simultaneously detect and differentiate B. henselae and B. quintana, a reliable and fast method to simultaneously detect and differentiate B. henselae and B. quintana is required. In this study, we developed and validated two rapid, highly sensitive and specific, duplex, real-time polymerase chain reaction (PCR) assays-one based on high-resolution melting (HRM) analysis, and the other on TaqMan probes-to simultaneously detect and differentiate B...

Ultrasound (US) is a well-established screening tool for detection of abdominal aortic aneurysms (AAAs) and is currently recommended not only for those with a relevant family history but also for all men and high-risk women older than 65 years of age. The advent of minimally invasive endovascular techniques in the treatment of AAAs [endovascular aneurysm repair (EVAR)] has increased the need for repeat imaging, especially in the postoperative period. Nevertheless, preoperative planning, intraoperative execution, and postoperative surveillance all mandate accurate imaging...

BACKGROUND: Deep Vein Thrombosis (DVT) is a common complication in trauma patients. Venous duplex surveillance is used widely for the diagnosis of DVT, however, there is controversy concerning its appropriate use. The Wells criterion is a clinically validated scoring system in an outpatient setting, but its use in trauma patients has not been studied. This study evaluated the application of the Wells scoring system in trauma population. METHODS: Wells scores were calculated retrospectively for all patients who were admitted to the trauma service and underwent Venous Duplex Scanning (VDS) at the author's institution between 2012 and 2013...
