Defining difficult intravenous access (DIVA): A systematic review.

J Vasc Access 2021 Nov 17:11297298211059648. Epub 2021 Nov 17.

Becton Dickinson and Co, Franklin Lakes, NJ, USA.

Background: The term "difficult intravenous access" (DIVA) is commonly used but not clearly defined. Repeated attempts at peripheral intravenous catheter (PIVC) insertion can be a traumatic experience for patients, leading to sub-optimal clinical and economic outcomes. We conducted a systematic literature review (SLR) to collate literature definitions of DIVA, with the aim of arriving at an evidence-driven definition. Read More

Assessment of the MAGIC recommendations in context of evolving evidence based on the use of PICC in ICU.

J Vasc Access 2021 Oct 23:11297298211048019. Epub 2021 Oct 23.

Department of Surgery, Catholic University Hospital, Rome, Italy.

The goal of the 2015 Michigan Appropriateness Guide for Intravenous Catheters (MAGIC) was to define indications and appropriate practices for peripherally inserted central catheters (PICC) use; however, MAGIC recommendations virtually reduced the use of PICC in hospital settings, including critical care. The aim of this review is to present an assessment of the MAGIC guidelines, considering contemporary evidence to date. The validity of the MAGIC recommendations and their applicability to current practice are called into question given important concerns with the methodology for their development (e. Read More

Faculty of Chemistry, Gdansk University of Technology, 11/12 Narutowicza St., Gdansk, 80-233, Poland.

Lake ecosystems are strongly coupled to features of their surrounding landscapes such as geomorphology, lithology, vegetation and hydrological characteristics. In the 2010-2018 summer seasons, we investigated an Arctic flow-through lake system Revvatnet, located in the vicinity of the coastal zone of Hornsund fjord in Svalbard, characterising its hydrological properties and the chemical composition of its waters. The lake system comprises of a small upper lake and a large lower one, the latter cone-shaped, with -29. Read More

On the Efficacy of Water Transport in Leaves. A Coupled Xylem-Phloem Model of Water and Solute Transport.

Front Plant Sci 2021 4;12:615457. Epub 2021 Feb 4.

Phenomics and Bioinformatics Research Centre, University of South Australia, Mawson Lakes, SA, Australia.

In this paper, we present and use a coupled xylem/phloem mathematical model of passive water and solute transport through a reticulated vascular system of an angiosperm leaf. We evaluate the effect of leaf width-to-length proportion and orientation of second-order veins on the indexes of water transport into the leaves and sucrose transport from the leaves. We found that the most important factor affecting the steady-state pattern of hydraulic pressure distribution in the xylem and solute concentration in the phloem was leaf shape: narrower/longer leaves are less efficient in convecting xylem water and phloem solutes than wider/shorter leaves under all conditions studied.

Dural Venous Channels: Hidden in Plain Sight-Reassessment of an Under-Recognized Entity.

AJNR Am J Neuroradiol 2020 08 16;41(8):1434-1440. Epub 2020 Jul 16.

From the Departments of Radiology (M.S., E.R., P.K.N.).

Background And Purpose: Tentorial sinus venous channels within the tentorium cerebelli connecting various cerebellar and supratentorial veins, as well as the basal vein, to adjacent venous sinuses are a well-recognized entity. Also well-known are "dural lakes" at the vertex. However, the presence of similar channels in the supratentorial dura, serving as recipients of the Labbe, superficial temporal, and lateral and medial parieto-occipital veins, among others, appears to be underappreciated.

Bioimaging Techniques Reveal Foliar Phosphate Uptake Pathways and Leaf Phosphorus Status.

Plant Physiol 2020 08 15;183(4):1472-1483. Epub 2020 Jun 15.

Department of Plant and Environmental Sciences, University of Copenhagen, 1871 Frederiksberg C, Denmark

Global demand for phosphorus (P) requires new agronomic practices to address sustainability challenges while increasing food production. Foliar P fertilization could increase P use efficiency; however, leaf entry pathways for inorganic phosphate ion (Pi) uptake remain unknown, and it is unclear whether foliar P applications can meet plant nutrient demands. We developed two techniques to trace foliar P uptake in P-deficient spring barley () and to monitor the effectiveness of the treatment on restoring P functionality. Read More

Clinical features, sex differences and outcomes of myocardial infarction with nonobstructive coronary arteries: a registry analysis.

Coron Artery Dis 2021 Jan;32(1):10-16

Department of Medicine, Bond University, Varsity Lakes, QLD Australia.

Introduction: Clinical characteristics and outcomes of patients diagnosed with myocardial infarction (MI) with nonobstructive coronary arteries (MINOCA) remain largely unknown. Furthermore, we do not yet understand if women with MINOCA have worse outcomes similar to what has historically been observed with MI. The aims of the current study were to evaluate the (1) incidence of MINOCA in patients presenting with MI, (2) compare in-hospital outcomes of MINOCA and obstructive atherosclerotic coronary artery disease MI (OACD-MI), and (3) comparison of in-hospital clinical outcomes of patients with MINOCA stratified by sex.

Vesicules or placental lakes in ultrasonography, determining the correct etiology.

J Gynecol Obstet Hum Reprod 2021 Jun 29;50(6):101738. Epub 2020 Apr 29.

Department of Obstetrics and Gynecology, Hospices Civils de Lyon, Hôpital Femme Mère Enfant, Université Claude Bernard, Lyon 1, Bron, Lyon 69500, France.

The prenatal examination of the placenta is often an afterthought to that of the fetus in ultrasonography. Not giving the placenta its due may however result in potentially serious placental pathologies remaining undiscovered, notably in the presence of anechoic zones. These latter have earned numerous names, including "placental lakes", "placental venous lakes", "placental lacunae" or "placental caverns" among others, but they have received little attention in the literature.
