Importance of carbon as limiting nutrient for bacterioplankton in a boreal sub-arctic coastal system.

Much debate has revolved around nutrient limitation in estuaries. A common view today is that nitrogen (N) and phosphorus (P) act as co-limiting nutrients, both for processes carried out by phytoplankton and by bacterioplankton, although recent studies show that also carbon (C) may control estuarine bacterioplankton, even in systems with large inputs of terrestrial organic matter (tOM). We conduct

WOMAC Osteoarthritis Index - Additional dimensions for use in subjects with post-traumatic osteoarthritis of the knee

Objective: To compare the sensitivity of WOMAC and the two added dimensions Sport and Recreation Function and Knee Related Quality of Life in subjects with radiographic knee OA to that in controls. To study the influence of age on the reported outcomes. Design: Outcomes were compared between subjects having had meniscectomy 21 years ago and which at time of follow-up had definite radiographic OA (

What are the outcomes after joint replacement?

Total hip replacement (THR) is an effective intervention with a good cost/benefit ratio. Worldwide, each year it brings relief in the form of improved function and decreased pain to at least half a million patients with severe osteoarthritis (OA). Since the introduction by Charnley more than 30 years ago, the basic concept remains much the same, but with a multitude of changes in details of surgic

Background: Osteoarthritis (OA) is the most common joint disease encountered throughout Europe. A task force for the EULAR standing committee for clinical trials met in 1998 to determine the methodological and logistical approach required for the development of evidence-based guidelines for treatment of knee OA. The guidelines were restricted to cover all currently available therapies for knee OA

Nano electrospray gas-phase electrophoretic mobility molecular analysis (nES GEMMA) of liposomes : Applicability of the technique for nano vesicle batch control

Liposomes are biodegradable nanoparticle vesicles consisting of a lipid bilayer encapsulating an aqueous core. Entrapped cargo material is shielded from the extra-vesicular medium and sustained release of encapsulated material can be achieved. However, application of liposomes as nano-carriers demands their characterization concerning size and size distribution, particle-number concentration, occu

Prognostic Impact of Chronic Total Occlusions : A Report From SCAAR (Swedish Coronary Angiography and Angioplasty Registry)

Objectives The aim of this study was to determine the prognostic impact of chronic total occlusion (CTO) on long-term mortality in a large prospective cohort. Background CTO is present in many patients with coronary artery disease and is difficult to treat with percutaneous coronary intervention. Methods The study population consisted of all consecutive patients who underwent coronary angiography

Levodopa-carbidopa intestinal gel (LCIG) treatment in routine care of patients with advanced Parkinson's disease : An open-label prospective observational study of effectiveness, tolerability and healthcare costs

Background Continuous infusion of levodopa-carbidopa intestinal gel (LCIG) can effectively manage motor and non-motor complications in advanced Parkinson's disease (PD). Healthcare costs, quality of life (QoL), effectiveness, and tolerability were assessed in routine care treatment with LCIG. Methods The seventy-seven patients enrolled in this prospective, open-label, 3-year study in routine medic

Reduction of Streptococcus pneumoniae in upper respiratory tract cultures and a decreased incidence of related acute otitis media following introduction of childhood pneumococcal conjugate vaccines in a Swedish county

Background: The effect of pneumococcal conjugate vaccines (PCV) on invasive pneumococcal disease is frequently reported, but the impact on upper respiratory tract infections in a clinical setting is less documented. Our aim in this 5-year observational study was to investigate serotype changes in a large number of Streptococcus pneumoniae upper respiratory tract isolates following sequential intro

Antibodies against Phosphorylcholine among New Guineans Compared to Swedes : An Aspect of the Hygiene/Missing Old Friends Hypothesis

Background: We here study antibodies against phosphorylcholine (anti-PC) which we reported to be inversely associated with atherosclerosis, cardiovascular disease (CVD), and autoimmune conditions. In previous studies, we determined that this inverse association is more pronounced at low levels with high risk and at high levels, with decreased risk. We compare individuals from Kitava, New Guinea (w

Markers of cartilage and synovial metabolism in joint fluid and serum of patients with chondromalacia of the patella

Objective: To further our understanding of the pathogenesis of chondromalacia of the patella (CM), we have studied the release into knee joint fluid and serum, obtained from patients with CM, of molecules associated with the metabolism of joint cartilage matrix and synovium. Methods: Interleukin-1 α (IL-1α), interleukin-1 β (IL-1β), interleukin-6 (IL-6), stromelysin-1 (MMP-3), interstitial collage

Risk Aversion and Guanxi Activities : A Behavioral Analysis of CEOs in China

In China, the strategic use of personal relationships is pervasive in transactions with government authorities as well as in inter-firm relations. Explanations as to when and why firms rely on guanxi emphasize a close link between organizational resources, environment and corporate strategic choices. Our study shifts attention to the importance of CEO preferences, specifically risk aversion, and s

OARSI recommendations for the management of hip and knee osteoarthritis, Part II : OARSI evidence-based, expert consensus guidelines

Purpose: To develop concise, patient-focussed, up to date, evidence-based, expert consensus recommendations for the management of hip and knee osteoarthritis (OA), which are adaptable and designed to assist physicians and allied health care professionals in general and specialist practise throughout the world. Methods: Sixteen experts from four medical disciplines (primary care, rheumatology, orth
