Maintenance of central venous access in patients with chronic medical conditions such as short bowel syndrome demands forethought and ingenuity. We describe an innovative technique for re-utilizing central venous access sites in patients who have chronic central venous access needs. Records of patients undergoing this technique were reviewed between August 2012 and December 2015. The technique involves "cutting-down" to the sterile fibrous tunnel that naturally forms around tunneled catheters. The fibrous sheath is then isolated and controlled much as would be done for a venous "cut-down...

We review the most comprehensive metabolic theory of life existing to date. A special focus is given to the thermodynamic roots of this theory and to implications that the laws of physics-such as the conservation of mass and energy-have on all life. Both the theoretical foundations and biological applications are covered. Hitherto, the foundations were more accessible to physicists or mathematicians, and the applications to biologists, causing a dichotomy in what always should have been a single body of work...

Currently, the specific capacity and cycling performance of various MoS2 /carbon-based anode materials for Na-ion storage are far from satisfactory due to the insufficient structural stability of the electrode, incomplete protection of MoS2 by carbon, difficult access of electrolyte to the electrode interior, as well as inactivity of the adopted carbon matrix. To address these issues, this work presents the rational design and synthesis of 3D interconnected and hollow nanocables composed of multiwalled carbon@MoS2 @carbon...

INTRODUCTION: It is unclear how many ultrasound-guided peripheral intravenous catheters (USG PIVC) one must place to become proficient at the procedure. The objective of this study was to determine the learning curve associated with PIVC placement and determine how many attempts are required for non-physician learners to reach proficiency. METHODS: This is a prospective observational study. Emergency department (ED) nurses and paramedics with competence in traditional PIVC placement underwent a USG PIVC placement training program...

BACKGROUND & OBJECTIVES: Intraosseous (IO) access is an alternative to difficult intravenous (iv) access during emergency clinical situations. Existing IO solutions are expensive, require power supply and trained manpower; limiting their use in resource constrained settings. To address these limitations, a novel IO device has been developed. The objectives of this study were to evaluate functionality and safety of this device in adult human cadavers. METHODS: The ability of the IO device to penetrate the proximal and/or distal tibia was evaluated in three adult cadavers...

UNLABELLED: Introduction Obtaining intravenous (IV) access in patients in hemorrhagic shock is often difficult and prolonged. Failed IV attempts delay life-saving treatment. Intraosseous (IO) access may often be obtained faster than IV access. Albumin (5%) is an option for prehospital volume expansion because of the absence of interference with coagulation and platelet function. Hypothesis/Problem There are limited data comparing the performance of IO and IV administered 5% albumin. The aims of this study were to compare the effects of tibial IO (TIO) and IV administration of 500 mL of 5% albumin on infusion time and hemodynamic measurements of heart rate (HR), mean arterial pressure (MAP), cardiac output (CO), and stroke volume (SV) in a swine model of hemorrhagic shock...

INTRODUCTION: Peripheral intravenous access (PIA) is a necessity in the treatment and monitoring of the majority of hospitalised patients. Patients with an increased body mass index (BMI) more often than normal-weight patients have a difficult PIA. Identifying veins with ultrasonography has proven helpful when facing a difficult intravenous (IV) access. We hypothesise that, with the help of ultrasonography (US), it is possible to identify at least one vein suitable for IV access in morbidly obese patients (BMI > 40 kg/m(2))...

N(2)-Furfuryl-deoxyguanosine (fdG) is carcinogenic DNA adduct that originates from furfuryl alcohol. It is also a stable structural mimic of the damage induced by the nitrofurazone family of antibiotics. For the structural and functional studies of this model N(2)-dG adduct, reliable and rapid access to fdG-modified DNAs are warranted. Toward this end, here we report the synthesis of fdG-modified DNAs using phosphoramidite chemistry involving only three steps. The functional integrity of the modified DNA has been verified by primer extension studies with DNA polymerases I and IV from E...

Peripheral intravenous (IV) access provides a means to administer medications, IV fluids, and blood products and allows for the sampling of blood for analysis. The traditional approach to obtaining peripheral IV access relies on vessel visualization in the arm and/or palpation of the blood vessel beneath the skin. However, the general population is aging, obesity is commonplace, and IV drug abuse is widespread, making peripheral IV access difficult. Use of ultrasound-guided peripheral IV access fills a practice gap in safe patient care between traditional peripheral IV access methods of vein visualization and/or palpation and ultrasound-guided central venous access...

A fundamental premise of this review is that distinctive phylogenetic and biogeographic patterns in clades endemic to different major biomes illuminate the evolutionary process. In seasonally dry tropical forests (SDTFs), phylogenies are geographically structured and multiple individuals representing single species coalesce. This pattern of monophyletic species, coupled with their old species stem ages, is indicative of maintenance of small effective population sizes over evolutionary timescales, which suggests that SDTF is difficult to immigrate into because of persistent resident lineages adapted to a stable, seasonally dry ecology...
