We describe a prospective observational cohort (N = 187) to evaluate peripherally inserted central catheter line complications concurrently from the time of placement until removal. A significantly higher percentage of patients who experienced intraluminal thrombosis were receiving total parenteral nutrition (P ≤ .001) and had a dual lumen catheter (P = .01). Among patients with a confirmed or suspected infection, a significantly higher proportion received total parenteral nutrition (P = .01), had dual-lumen catheters (P = ...

PURPOSE: To evaluate long-term refractive outcomes of implantable collamer lens (ICL) implantation and late postoperative complications. METHODS: We assessed outcomes of patients who underwent ICL implantation (type ICM V4 for myopia, ICH V3 for hyperopia, TICM V4 for astigmatism) in our department between 1998 and 2013. It comprised 62 eyes (40 myopic and 22 hyperopic). The average follow-up period was 10.5 years. We evaluated: uncorrected and best-corrected visual acuity (UCVA and BCVA), spherical equivalent (SE), ICL vault, endothelial cell density and late postoperative complications...

It has been widely accepted that longer single-walled carbon nanotubes (SWCNTs) exhibit higher toxicity by causing severe pneumonia once inhaled, yet relatively little is known regarding the potential toxicity of ultrashort SWCNTs, which are of central importance to their development as suitable vehicles for biomedical applications. Here, by combining coarse-grained molecular dynamics (CGMD), pulling simulations, and scaling analysis, we demonstrate that the inhalation toxicity of ultrashort SWCNTs (1.5 nm < l < 5...

OBJECTIVES: Fluorescein Sodium (FL) enhances areas in the brain with a disrupted blood brain barrier (BBB). Solitary brain abscesses (BA) are characterized by the pathognomonic finding of BBB disruption. Consequently, FL may have the potential to improve the intra-operative visualization of BA. Here, we report a series of patients with BA that where treated surgically after application of FL in combination with a dedicated light filter integrated in the surgical microscope. METHODS: 7 patients (4 female, 3 male; mean age 53...

PURPOSE: To evaluate incidence and risk factors of peripherally inserted central catheter (PICC)-related complications in cancer patients. METHODS: A prospective, multicenter, cohort study of cancer patients with PICC insertion was performed from February 1, 2013 to April 24, 2014. All patients were monitored in clinic until PICCs were removed. The primary endpoint was PICC removal due to complications. Patient-, catheter- and insertion-related factors were analyzed in univariable and multivariable logistic regression analysis to identify significant independent risk factors for PICC-related complications...

A hallmark of acute respiratory distress syndrome (ARDS) is accumulation of protein-rich edema in the distal airspaces and its removal is critical for patient survival. Previous studies have shown a detrimental role of Glycogen Synthase Kinase (GSK) 3β during ARDS via inhibition of alveolar epithelial protein transport. We hypothesized that post-transcriptional regulation of GSK3β could play a functional role in ARDS resolution. To address this hypothesis, we performed an in silico analysis to identify regulatory genes whose expression correlation to GSK3β messenger RNA utilizing two lung cancer cell line array datasets...

In this study, we report an interaction study of a 13-residue analogue peptide VG13P (VARGWGRKCPLFG), derived from a designed VG16KRKP peptide (VARGWKRKCPLFGKGG), with a Lys6Gly mutation and removal of the last three residues Lys(14)-Gly(15)-Gly(16), in lipopolysaccharide (LPS), a major component of the outer membrane of Gram-negative bacteria and responsible for sepsis or septic shock. VG13P displays an enhanced anti-endotoxin property as evident from significant reduction in LPS-induced TNF-α gene expression levels in a monocytic cell line, while it retains almost unchanged antimicrobial activity as its parent VG16KRKP against Gram-negative bacterial as well as fungal pathogens...

INTRODUCTION: Preservation of venous access in children is a major concern in pediatric interventional radiology. If a peripherally inserted central catheter (PICC) breaks, there are two options: repair the line with a repair kit or exchange the line over a wire in the interventional suite. The purpose of this study is to assess the outcome of PICC repairs in children and to compare these with the outcomes of PICC exchange. MATERIALS AND METHODS: This is a single-center, retrospective study of central line-associated bloodstream infection (CLABSI) following management of externally broken PICCs (2010-2014)...

Brown rot fungi are wood-degrading fungi that employ both oxidative and hydrolytic mechanisms to degrade wood. Hydroxyl radicals that facilitate the oxidative component are powerful non-selective oxidants and are incompatible with hydrolytic enzymes unless they are spatially segregated in wood. Differential gene expression has been implicated in Postia placenta to segregate these reactions, but it is unclear if this two-step mechanism varies in other brown rot fungi with different traits and life history strategies, and that occupy different niches in nature...

Current practices for the management of Barrett's esophagus (BE) vary across Europe, as several national European guidelines exist. This Position Statement from the European Society of Gastrointestinal Endoscopy (ESGE) is an attempt to homogenize recommendations and, hence, patient management according to the best scientific evidence and other considerations (e.g. health policy). A Working Group developed consensus statements, using the existing national guidelines as a starting point and considering new evidence in the literature...

We investigated dwell times and risk of non-elective removal of 975 single-lumen 1-French peripherally inserted central catheters (1FR-PICC) according to tip position in a cohort of very preterm infants with a mean (SD) gestational age of 27(+6) (2(+1)) weeks and a mean (SD) birth weight of 988 (294) g over an eight-year period. Infants with a 1FR-PICC inserted for continuous infusion of intravenous fluids within the first 30 days of life were eligible. Dwell times of PICC with elective versus non-elective removal, risk of non-elective removal of PICC according to tip position, and differences between upper versus lower limb catheter insertion were analysed...

BACKGROUND: Leukemic and mesenchymal stem cells interact in the leukemic microenvironment and affect each other differently. This interplay has also important implications for the hematopoietic stem cell (HSC) biology and function. This study evaluated human HSC self-renewal potential and quiescence in an in vitro leukemic niche without leukemic cells. METHODS: A leukemic niche was established by co-culturing mesenchymal stem cells with a fresh conditioned medium obtained from a leukemic (REH) cell line...

BACKGROUND AND OBJECTIVES: The placement of a peripherally inserted central venous catheter (PICC) is an essential procedure in neonatal intensive care units (NICU). The aim of this study was to determine the risk of PICC complications in NICU, and further identify the effects of PICC complications on body weight gain in premature infants. METHODS AND STUDY DESIGN: A total of 304 premature infants who had a PICC inserted in NICU were enrolled in this study. The weight-for-age z-score (WAZ) at the time of PICC insertion and removal were calculated, and changes of WAZ in different groups were compared using a t-test...

In 2014, the World Health Organization (WHO) recommendation to include the endorsed rapid molecular technologies (Xpert MTB/RIF, line probe assays) into surveillance systems and surveys allowed the testing of more tuberculosis (TB) patients for drug resistance at country level than ever before. The whole genome sequencing (WGS) approach is emerging as a more powerful tool for epidemiological and drug-resistant routine surveillances, promising a rapid and simultaneous screening of all the clinically-relevant mutations for the determination of resistance to the first-, second-line, and new anti-TB drugs...

Increasingly, peripherally inserted central catheters (PICC) are applied in patients with haematological malignancies. The feasibility and safety of PICC for induction chemotherapy in acute myeloid leukaemia (AML) remain unclear. Medical records of 89 newly diagnosed adult de novo AML patients, who achieved complete remission, were retrospectively reviewed (PICC group, n = 43; intravenous [IV] line group, n = 46). Patients' clinical characteristics and the number of blind punctures for blood sampling were compared between these two groups, and risk factors associated with bacteraemia were identified by univariate analysis...

REVIEW
Maggie J Westby, Gill Norman, Jo C Dumville, Nikki Stubbs, Nicky Cullum
BACKGROUND: Venous leg ulcers (VLUs) are open skin wounds on the lower leg that occur because of poor blood flow in the veins of the leg; leg ulcers can last from weeks to years, and are both painful and costly. Prevalence in the UK is about 2.9 cases per 10,000 people. First-line treatment for VLUs is compression therapy, but around 60% of people have unhealed ulcers after 12 weeks' treatment and about 40% after 24 weeks; therefore, there is scope for further improvement. Limited evidence suggests non-healing leg ulcers may have persisting elevated levels of proteases, which is thought to deter the later stages of healing; thus, timely protease-modulating matrix (PMM) treatments may improve healing by physically removing proteases from the wound fluid...
