  • Oxygen saturation and perfusion index screening in neonates at high altitudes: can PDA be predicted? [Journal Article]
    Eur J Pediatr. 2020 Jun 05 [Online ahead of print]Tekgündüz KŞ, Bilen M, … Ceviz N
  • CONCLUSIONS: The median peripheral perfusion index at high altitude was not lower than at sea level, while the mean oxygen saturation, in contrast, was lower than at sea level. The low partial oxygen pressure found at high altitudes leads to a variation in postnatal adaptation and an increased prevalence of PDA. Accordingly, oxygen saturation screening may serve to identify babies with PDA at high altitudes.What is Known:• Oxygen saturation is known to be low at high altitudes, and thus the rates of false positivity are high when screening for critical congenital heart disease.• High altitudes are also associated with an increased prevalence of simple congenital heart disease.What is New:• The peripheral perfusion index at high altitude is not lower than at sea level.• The prevalence of PDA is significantly higher in those with false positive screening results.
  • Optical Coherence Tomography Angiography in Diabetes and Diabetic Retinopathy. [Review]
    J Clin Med. 2020 Jun 03; 9(6)Chua J, Sim R, … Schmetterer L
  • Diabetic retinopathy (DR) is a common complication of diabetes mellitus that disrupts the retinal microvasculature and is a leading cause of vision loss globally. Recently, optical coherence tomography angiography (OCTA) has been developed to image the retinal microvasculature, by generating 3-dimensional images based on the motion contrast of circulating blood cells. OCTA offers numerous benefit…
  • Brachial Artery Injuries Operative Management and Predictors of Outcome. [Journal Article]
    Ann Vasc Surg. 2020 Jun 02 [Online ahead of print]Asensio JA, Miljkovic SS, … Rowe VL
  • CONCLUSIONS: Brachial artery injuries are rare and pose challenges to Trauma and Vascular Surgeons. Patients not requiring ED Thoracotomy, GCS, ISS, and EBL predicted survival. Out adjusted limb Salvage rate - 98.3%. Patients succumbing with brachial artery injuries die from associated injuries and thus experience less ischemic times than survivors who are able to undergo repairs.
  • Integrating regional perfusion CT information to improve prediction of infarction after stroke. [Journal Article]
    J Cereb Blood Flow Metab. 2020 Jun 05 [Online ahead of print]Klug J, Dirren E, … Carrera E
  • Physiological evidence suggests that neighboring brain regions have similar perfusion characteristics (vascular supply, collateral blood flow). It is largely unknown whether integrating perfusion CT (pCT) information from the area surrounding a given voxel (i.e. the receptive field (RF)) improves the prediction of infarction of this voxel. Based on general linear regression models (GLMs) and usin…
  • Pressure and flow properties of dual-lumen cannulae for extracorporeal membrane oxygenation. [Journal Article]
    Perfusion. 2020 Jun 05 [Online ahead of print]Broman LM, Westlund CJ, … Lorusso R
  • CONCLUSIONS: Non-standardized testing of pressure-flow properties of extracorporeal membrane oxygenation dual-lumen cannulae prevents an adequate prediction of pressure-flow results when these cannulae are used in patients. Properties of dual-lumen cannulae may vary between sizes within same cannula family, in particular concerning the drainage flow.
  • The regional pattern of abnormal cerebrovascular reactivity in HIV-infected, virally suppressed women. [Journal Article]
    J Neurovirol. 2020 Jun 04 [Online ahead of print]Callen AL, Dupont SM, … Narvid J
  • The purpose of this study was to assess whole brain and regional patterns of cerebrovascular reactivity (CVR) abnormalities in HIV-infected women using quantitative whole brain arterial spin labeling (ASL). We hypothesized that HIV-infected women would demonstrate decreased regional brain CVR despite viral suppression. This cross-sectional study recruited subjects from the Bay Area Women's Intera…
  • CZT camera systems may provide better risk stratification for low-risk patients. [Journal Article]
    J Nucl Cardiol. 2020 Jun 04 [Online ahead of print]Miller RJH, Han D, … Berman DS
  • CONCLUSIONS: Increasing stress perfusion abnormality was associated with similar increase in all-cause mortality with CZT or NaI cameras. CZT and NaI camera systems provide similar risk stratification, however, normal myocardial perfusion may be associated with a more benign prognosis when assessed with a CZT camera system.
  • Exploration of movement artefacts in handheld laser speckle contrast perfusion imaging. [Journal Article]
    Biomed Opt Express. 2020 May 01; 11(5):2352-2365.Chizari A, Knop T, … Steenbergen W
  • Functional performance of handheld laser speckle contrast imaging (LSCI) is compromised by movement artefacts. Here we quantify the movements of a handheld LSCI system employing electromagnetic (EM) tracking and measure the applied translational, tilt and on-surface laser beam speeds. By observing speckle contrast on static objects, the magnitudes of translation and tilt of wavefronts are explore…
  • Immunity and Stress Responses Are Induced During Ex Situ Heart Perfusion. [Journal Article]
    Circ Heart Fail. 2020 Jun 05 [Online ahead of print]Hatami S, White CW, … Freed DH
  • CONCLUSIONS: Myocardial function declines during ESHP regardless of perfusion mode. However, ESHP in WM may lead to superior preservation of myocardial function and viability. Both inflammation and endoplasmic reticulum stress responses are significantly induced during ESHP and may contribute to the myocardial functional decline, representing a potential therapeutic target to improve the clinical donor heart preservation.
  • Advances in the Diagnosis of Venous Thromboembolism: A Literature Review. [Review]
    Diagnostics (Basel). 2020 Jun 02; 10(6)Patel H, Sun H, … Vakde T
  • The incidence of venous thromboembolism (VTE), including lower extremity deep vein thrombosis (DVT) and pulmonary embolism (PE) is increasing. The increase in suspicion for VTE has lowered the threshold for performing imaging studies to confirm diagnosis of VTE. However, only 20% of suspected cases have a confirmed diagnosis of VTE. Development of pulmonary embolism rule-out criteria (PERC) and u…
