Effect of size on concentrations and cadmium inducibility of metallothionein in the shore crab Carcinus maenas.

Metallothionein (MT) plays an important role in protecting organisms from the adverse effects of Cd, Hg, Zn and Cu. Investigations on mammals show variations in metallothionein concentrations and inducibility with age. This has never been investigated in invertebrates, and we determined the concentrations and inducibility of metallothionein in gills and midgut gland of different size classes of shore crabs from uncontaminated areas.

Stabilisation of Automated Refraction in the Immediate Time After Uneventful Cataract Surgery.

Introduction: To determine which day automated refraction stabilised the first week after uneventful cataract surgery.

Methods: This was a prospective, single-blinded, randomised cohort study of 148 eyes in 148 consecutive patients undergoing uneventful cataract surgery. Automated refraction was measured from days 2 to 7 after surgery and compared to automated refraction measured 6 weeks post-surgery.

Use of standard test organisms for sound validation of UV-based ballast water treatment systems.

To challenge ballast water treatment system (BWTS) efficacy for organisms in the size-class 10-50 μm, intake concentration during tests must reach certain minimum requirements. Often, natural concentrations are too low to meet intake requirements and standard test organisms (STOs) are added. We tested the robustness of Tetraselmis suecica and Odontella sp.

UV fluences required for compliance with ballast water discharge standards using two approved methods for algal viability assessment.

This study investigates the extra UV fluence needed to meet the International Maritime Organisation's ballast water discharge standards for the 10-50 μm size-class using the approved vital stain (VS) method compared to the Most Probable Number (MPN) method for organism viability assessment. Low- and medium pressure UV collimated beam treatments were applied to natural algae collected in temperate and tropical water environments and analysed using both methods. About 10 times higher UV fluence was required to meet discharge standards when using VS compared to MPN.

Difference between SF and N multiple breath washout kinetics is due to N back diffusion and error in N offset.

Measurement of lung clearance index (LCI) by multiple breath washout (MBW) is a sensitive method for monitoring lung disease in patients with cystic fibrosis (CF). To compare nitrogen MBW (N-MBW) and sulfur hexafluoride MBW (SF-MBW), we connected these two gas analysis systems in series to obtain truly simultaneous measurements, with no differences other than the gas used. Nonsmoking healthy controls (HC) and subjects with CF were recruited at two institutions.

Retention and distribution of methylmercury administered in the food in marine invertebrates: Effect of dietary selenium.

Methylmercury is transported along aquatic food chains from the lower trophic levels and selenium modulates the biokinetics of mercury in organisms in complex ways. We investigated the retention of orally administered methylmercury in various marine invertebrates and the effect of selenium hereon. Shrimps (Palaemon adpersus and P.

Vitellogenin concentrations in feral Danish brown trout have decreased: An effect of improved sewage treatment in rural areas?

Feminization of male and juvenile fish because of exposure to estrogens or estrogenic chemicals in effluents from central wastewater treatment plants (WWTPs) is a worldwide issue of concern. Intersex and induction of the female yolk protein, vitellogenin, in male and juvenile fish are robust biomarkers for estrogenic exposure, and feminized fish have been observed downstream of WWTP outlets in many countries. Danish central WWTPs reduce effluent estrogenicity effectively by advanced sewage treatment, and feminizations have not been observed downstream of central WWTP outlets.

New time-saving predictor algorithm for multiple breath washout in adolescents.

Background: Multiple breath washout (MBW) is an informative but time-consuming test. This study evaluates the uncertainty of a time-saving predictor algorithm in adolescents.

Methods: Adolescents were recruited from the Copenhagen Prospective Study on Asthma in Childhood (COPSAC2000) birth cohort.

Purpose: To investigate the correlation between the retinal vascular fractal dimension (Fd) and neurodegenerative changes in patients with no or mild diabetic retinopathy (DR).

Methods: In this cross-sectional study we examined 103 patients with type 2 diabetes mellitus (T2DM) with no or mild DR. In a randomly selected eye of each patient, Fd was calculated using SIVA-Fractal, a specialized semiautomatic software.

Impact of chronic obstructive pulmonary disease on survival and symptoms of severe aortic valve stenosis.

Background: As patients with severe aortic valve stenosis (AS) develop symptoms their survival decreases rapidly, if treated conservatively. Transcatheter aortic valve implantation (TAVI) has been introduced as a less invasive treatment alternative, especially in inoperable patients, who often have severe comorbidities, including chronic obstructive pulmonary disease (COPD).

Materials And Methods: Since the beginning of our TAVI program in March 2008, data on all 131 TAVI patients were prospectively and consecutively collected in this registry with complete follow-up.

Influence of cardiogenic shock with or without the use of intra-aortic balloon pump on mortality in patients with ST-segment elevation myocardial infarction.

Background: Cardiogenic shock is a serious complication of a ST-segment elevation myocardial infarction (STEMI). We compared short- and long-term mortality among (1) STEMI patients with and without cardiogenic shock and (2) STEMI patients with cardiogenic shock with and without the use of an intra-aortic balloon pump (IABP).

Methods: From January 1, 2002 to December 31, 2010, all patients presenting with STEMI and treated with primary percutaneous coronary intervention (PCI) were identified.

Evaluation of yolk protein levels as estrogenic biomarker in bivalves; comparison of the alkali-labile phosphate method (ALP) and a species-specific immunoassay (ELISA).

Altered concentration of the vertebrate yolk protein precursor vitellogenin is a recognized biomarker for endocrine disruption in fish, and within recent years yolk protein alteration has also been associated with endocrine disruption in bivalves. Species-specific, direct and sensitive methods for quantification of vitellogenin in fish have been available for years whereas bivalve yolk protein levels have been estimated indirectly by alkali-labile phosphate (ALP) liberated from high molecular weight proteins because the sequence and biochemical structure of most bivalve yolk proteins are unknown. By applying a species-specific enzyme-linked immunosorbent assay (ELISA) for accurate determination of yolk protein level the impact of 17β-estradiol (57, 164 and 512 ng/L) on the freshwater bivalve Unio tumidus was investigated and compared with ALP estimations.

Amount and metal composition of midgut gland metallothionein in shore crabs (Carcinus maenas) after exposure to cadmium in the food.

Accumulation of cadmium in aquatic invertebrates may compromise human food safety and anthropogenic additions of cadmium to coastal areas cause concern. Induction of crustacean metallothionein has been suggested as a useful biomarker for contamination of the aquatic environment with cadmium. We investigated how exposure to low concentrations of cadmium in the food affects the subcellular binding of cadmium with the shore crab Carcinus maenas as model organism.

Vitellogenin as biomarker for estrogenicity in flounder Platichthys flesus in the field and exposed to 17α-ethinylestradiol via food and water in the laboratory.

The ability of 17α-ethinylestradiol (EE2) to elevate vitellogenin levels were investigated in male flounder Platichthys flesus and vitellogenin concentrations in flounders from the Danish coastal environment were determined. Male flounders were exposed to 17α-ethinylestradiol (EE2) via food or water. Average vitellogenin concentrations in the control fish ranged between 25 and 100 ng mL(-)(1).

The Long-Term Multicenter Observational Study of Dabigatran Treatment in Patients With Atrial Fibrillation (RELY-ABLE) Study.

Background: During follow-up of between 1 and 3 years in the Randomized Evaluation of Long-term Anticoagulation Therapy (RE-LY) trial, 2 doses of dabigatran etexilate were shown to be effective and safe for the prevention of stroke or systemic embolism in patients with atrial fibrillation. There is a need for longer-term follow-up of patients on dabigatran and for further data comparing the 2 dabigatran doses.

Methods And Results: Patients randomly assigned to dabigatran in RE-LY were eligible for the Long-term Multicenter Extension of Dabigatran Treatment in Patients with Atrial Fibrillation (RELY-ABLE) trial if they had not permanently discontinued study medication at the time of their final RE-LY study visit.

Context: The effectiveness of postoperative analgesia through a wound catheter is subject to considerable debate.

Objective: To test the hypothesis that local wound infusion with bupivacaine followed by continuous infusion could reduce postoperative need for opioids in patients undergoing retropubic prostatectomy.

Design: Single-centre prospective, double-blinded, placebo-controlled trial.

Randomized comparison of everolimus-eluting and sirolimus-eluting stents in patients treated with percutaneous coronary intervention: the Scandinavian Organization for Randomized Trials with Clinical Outcome IV (SORT OUT IV).

Background: Among drug-eluting stents released to date, the sirolimus-eluting stent has demonstrated the least amount of late lumen loss, but its efficacy and safety have not been compared head-to-head with the next-generation everolimus-eluting stent.

Methods And Results: The Scandinavian Organization for Randomized Trials with Clinical Outcome IV (SORT OUT IV) trial was a randomized multicenter, single-blind, all-comer, 2-arm, noninferiority trial comparing the everolimus-eluting stent with the sirolimus-eluting stent in patients with coronary artery disease. The primary end point was a composite of safety (cardiac death, myocardial infarction, definite stent thrombosis) and efficacy (target vessel revascularization) parameters.

Late lumen loss and intima hyperplasia after sirolimus-eluting and zotarolimus-eluting stent implantation in diabetic patients: the diabetes and drug-eluting stent (DiabeDES III) angiography and intravascular ultrasound trial.

Aims: Patients with diabetes mellitus have increased risk of in-stent restenosis after coronary stent implantation due to neointimal hyperplasia (NIH). The aim of this study was to use quantitative coronary angiography (QCA) and volumetric intravascular ultrasound (IVUS) to evaluate the effects of the sirolimus-eluting Cypher® stent (SES) and the zotarolimus-eluting Endeavor® stent (ZES) on angiographic late lumen loss and intima hyperplasia in diabetic patients.

Methods And Results: In the DiabeDES III trial, 127 patients were randomised to SES or ZES stent implantation.

Genetic adaptation of earthworms to copper pollution: is adaptation associated with fitness costs in Dendrobaena octaedra?

Exposure to copper pollution affects reproduction, growth and survival of earthworms. It is known that earthworms can cope with high copper burdens, but the distinction between physiological acclimation and evolutionary heritable changes and associated fitness consequences of the adaption to long-term copper exposure has rarely been studied. To investigate adaptation of earthworm populations of Dendrobaena octaedra to copper contamination, three populations from polluted soil were studied and compared to three unpolluted reference sites.

Mini-laparotomy approach to radical cystectomy.

Objective: • To investigate the feasibility of performing radical cystectomy (RC) through a mini-laparotomy and to evaluate the effect of a smaller incision on wound problems, immediate postoperative pain, bowel function and length of hospital stay (LOS).

Patients And Methods: • Two consecutive cohorts of patients, one with 75 patients undergoing open RC (ORC) with lymph node dissection up to the aortic bifurcation through a conventional long midline incision and one with 75 patients undergoing RC through a mini-laparotomy (MinilapRC) of intentionally <8-10 cm. • Patient characteristics, operative duration, estimated blood loss (EBL), incidence and severity of wound problems, return of bowel function, amount of analgesics needed and LOS were analysed according to the intention-to-treat principle.

Rationale and design of a randomized clinical comparison of everolimus-eluting (Xience v/Promus) and sirolimus-eluting (cypher select+) coronary stents in unselected patients with coronary heart disease.

Background: The sirolimus-eluting stent has demonstrated the least amount of late lumen loss among previously released drug-eluting stents, but its safety and efficacy has not been compared head-to-head with the everolimus-eluting stent.

Method: The Scandinavian Organization for Randomized Trials with Clinical Outcome (SORT OUT) IV trial was designed as a prospective, multi-center, open-label, all-comer, two-arm, randomized, non-inferiority study comparing the everolimus-eluting stent with the sirolimus-eluting stent in the treatment of atherosclerotic coronary artery lesions. Based on a non-inferiority design, power calculations estimated a needed enrolment of 2,678 patients.

[Use of prostate-specific antigen testing].

Background: Prostate cancer (PC) is the most frequent type of cancer among Danish men and its incidence is rising. PC is often asymptomatic, which makes it very difficult to diagnose clinically. The general practitioner can use prostate-specific antigen (PSA) testing as a diagnostic tool in PC.
