Iohexol plasma clearance for measuring glomerular filtration rate in clinical practice and research : A review. Part 1: How to measure glomerular filtration rate with iohexol?

While there is general agreement on the necessity tomeasure glomerular filtration rate (GFR) inmany clinical situations, there is less agreement on the bestmethod to achieve this purpose. As the gold standardmethod for GFR determination, urinary (or renal) clearance of inulin, fades into the background due to inconvenience and high cost, a diversity of filtrationmarkers and protocols compete to re

Risk of future microvascular and macrovascular disease in people with Type 1 diabetes of very long duration : A national study with 10-year follow-up

Aims: To describe factors associated with prevalence or absence of microvascular and macrovascular complications in people with Type 1 diabetes of very long duration and to investigate the risk factors associated with the incidence of such complications. Methods: We included individuals with Type 1 diabetes who had been entered in the Swedish National Diabetes Register between 2002 and 2004 (n = 1

Host–pathogen interactions of nontypeable Haemophilus influenzae : from commensal to pathogen

Nontypeable Haemophilus influenzae (NTHi) is a commensal microbe often isolated from the upper and lower respiratory tract. This bacterial species can cause sinusitis, acute otitis media in preschool children, exacerbations in patients suffering from chronic obstructive pulmonary disease, as well as conjunctivitis and bacteremia. Since the introduction of a vaccine against H. influenzae serotype b

On the association between weather variability and total and cause-specific mortality before and during industrialization in Sweden

BACKGROUND While there is ample evidence for health risks associated with heat and other extreme weather events today, little is known about the impact of weather patterns on population health in preindustrial societies.OBJECTIVETo investigate the impact of weather patterns on population health in Sweden before and during industrialization.METHODSWe obtained records of monthly mortality and of mon

Specific inhibition of TRPV4 enhances retinal ganglion cell survival in adult porcine retinal explants

Signaling through the polymodal cation channel Transient Receptor Potential Vanilloid 4 (TRPV4) has been implicated in retinal neuronal degeneration. To further outline the involvement of this channel in this process, we here explore modulation of Transient Receptor Potential Vanilloid 4 (TRPV4) activity on neuronal health and glial activation in an in vitro model of retinal degeneration. For this

Drugs in pregnancy - the dilemma of labeling

The paper discusses the problems with pregnancy labeling of drugs. The Swedish, United States, and Australian labeling systems are briefly summarized. Data on drug use in early pregnancy in Sweden (1996) are presented according to pregnancy labeling category and with details on drugs thought to be teratogenic or where animal data suggest hazards. The various situations when drug teratogenicity are

Access to drinking water and sanitation in rural Kazakhstan

The Sustainable Development Goals (SDGs) require nations to ensure adequate water supply for all. For Kazakhstan, this means that rural areas will need much stronger attention as they have been rather neglected in efforts to comply with the Millennium Development Goals (MDGs). This study aims to establish a baseline data concerning the current situation in villages that will need interventions acc

Vision on the high seas : Spatial resolution and optical sensitivity in two procellariiform seabirds with different foraging strategies

Procellariiform or 'tubenosed' seabirds are challenged to find prey and orient over seemingly featureless oceans. Previous studies have found that life-history strategy (burrow versus surface nesting) was correlated to foraging strategy. Burrow nesters tended to track prey using dimethyl sulphide (DMS), a compound associated with phytoplankton, whereas surface-nesting species did not. Burrow neste

Observer-Based Strictly Positive Real (SPR) Variable Structure Output Feedback Control

This paper considers switching output feedback control of linear systems and variable-structure systems. Theory for stability analysis and design for a class of observer-based feedback control systems is presented. A circle-criterion approach can be used to design an observer-based state feedback control which yields a closed-loop system with specified robustness characteristics. The approach is r

SPINART study : validation of the extended magnetic resonance imaging scale for evaluation of joint status in adult patients with severe haemophilia A using baseline data

Introduction: Most previous joint imaging scales for haemophilia have focused on earlier disease stages observed in younger patients. Aim: We sought to demonstrate that the 45-item extended magnetic resonance imaging (eMRI) scale is a valid instrument for measuring joint status in adults with severe haemophilia A. Methods: Six scale categories (effusion/haemarthrosis, synovial hypertrophy, hemosid

Prevalence of human papillomavirus types, viral load and physical status of HPV16 in head and neck squamous cell carcinoma from the South Swedish Health Care Region

Incidence of human papillomavirus (HPV)-positive head and neck squamous cell carcinoma (HNSCC) is rising in several countries. Intriguingly, large variations of HPV16 viral load and different proportions of the physical viral status among HNSCC have been reported. We analysed fresh biopsies of 275 HNSCC patients from the South Swedish Health Care Region for HPV types with modified general primer P

Development of the ClinESSDAI : A clinical score without biological domain. A tool for biological studies

Objective To develop and validate ClinESSDAI (Clinical European League Against Rheumatism Sjögren's Syndrome Disease Activity Index), ie, ESSDAI without the biological domain. Patients and methods The 702 fictive vignettes derived from 96 real cases of primary Sjögren's syndrome of the ESSDAI development study were used. As for ESSDAI development, the physician assessment of disease activity (0-10

Analysis of C9orf72 repeat expansions in a large international cohort of dementia with Lewy bodies

. C9orf72 repeat expansions are a common cause of amyotrophic lateral sclerosis and frontotemporal dementia. To date, no large-scale study of dementia with Lewy bodies (DLB) has been undertaken to assess the role of . C9orf72 repeat expansions in the disease. Here, we investigated the prevalence of . C9orf72 repeat expansions in a large cohort of DLB cases and identified no pathogenic repeat expan

Water-related impacts of climate change on agriculture and subsequently on public health : A review for generalists with particular reference to Pakistan

Water-related impacts due to change in climatic conditions ranging from water scarcity to intense floods and storms are increasing in developing countries like Pakistan. Water quality and waterborne diseases like hepatitis, cholera, typhoid, malaria and dengue fever are increasing due to chaotic urbanization, industrialization, poor hygienic conditions, and inappropriate water management. The morb

Silica uptake and release in live and decaying biomass in a northern hardwood forest

In terrestrial ecosystems, a large portion (20-80%) of the dissolved Si (DSi) in soil solution has passed through vegetation. While the importance of this terrestrial Si filter is generally accepted, few data exist on the pools and fluxes of Si in forest vegetation and the rate of release of Si from decomposing plant tissues. We quantified the pools and fluxes of Si through vegetation and coarse w
