Missed low-grade infection in suspected aseptic loosening has no consequences for the survival of total hip arthroplasty.

Background And Purpose: Aseptic loosening and infection are 2 of the most common causes of revision of hip implants. Antibiotic prophylaxis reduces not only the rate of revision due to infection but also the rate of revision due to aseptic loosening. This suggests under-diagnosis of infections in patients with presumed aseptic loosening and indicates that current diagnostic tools are suboptimal.

Prognosis and Treatment After Diagnosis of Recurrent Esophageal Carcinoma Following Esophagectomy with Curative Intent.

Background: Strategies for the treatment of recurrence after initial curative esophagectomy are increasingly being recognized. The aim of this study was to identify prognostic factors that affect survival in patients with recurrence and to evaluate treatment strategies.

Methods: A prospective database (2003-2013) was used to collect consecutive patients with esophageal carcinoma treated with initial curative esophagectomy.

Mental health care use in adolescents with and without mental disorders.

The aim of the study was to estimate the proportion of adolescents with and without a psychiatric diagnosis receiving specialist mental health care and investigate their problem levels as well as utilization of other types of mental health care to detect possible over- and undertreatment. Care utilization data were linked to psychiatric diagnostic data of 2230 adolescents participating in the TRAILS cohort study, who were assessed biannually starting at age 11. Psychiatric diagnoses were established at the fourth wave by the Composite International Diagnostic Interview.

High-resolution quantification of root dynamics in split-nutrient rhizoslides reveals rapid and strong proliferation of maize roots in response to local high nitrogen.

The plant's root system is highly plastic, and can respond to environmental stimuli such as high nitrogen (N) in patches. A root may respond to an N patch by selective placement of new lateral roots, and therewith increases root N uptake. This may be a desirable trait in breeding programmes, since it decreases NO3(-) leaching and N2O emission.

Life cycle stage and water depth affect flooding-induced adventitious root formation in the terrestrial species Solanum dulcamara.

Background And Aims: Flooding can occur at any stage of the life cycle of a plant, but often adaptive responses of plants are only studied at a single developmental stage. It may be anticipated that juvenile plants may respond differently from mature plants, as the amount of stored resources may differ and morphological changes can be constrained. Moreover, different water depths may require different strategies to cope with the flooding stress, the expression of which may also depend on developmental stage.

The influence of pretreatment methods on saccharification of sugarcane bagasse by an enzyme extract from Chrysoporthe cubensis and commercial cocktails: A comparative study.

Biomass enzymatic hydrolysis depends on the pretreatment methods employed, the composition of initial feedstock and the enzyme cocktail used to release sugars for subsequent fermentation into ethanol. In this study, sugarcane bagasse was pretreated with 1% H2SO4 and 1% NaOH and the biomass saccharification was performed with 8% solids loading using 10 FPase units/g of bagasse of the enzymatic extract from Chrysoporthe cubensis and three commercial cocktails for a comparative study. Overall, the best glucose and xylose release was obtained from alkaline pretreated sugarcane bagasse.

[Functional remission of people with serious mental illness (SMI): psychometric properties of a new ROM-instrument].

Background: Instruments are used for routine outcome monitoring of patients with severe mental illness in order to measure psychiatric symptoms, care needs and quality of life. By adding an instrument for measuring functional remission a more complete picture can be given of the complaints, the symptoms and general functioning, which can give direction to providing care for patients with severe mental illness.

Aim: To describe the development and testing of a new instrument of functional remission (FR) among people with a psychotic disorder or another serious mental disorder (SMI) as an addition to the symptomatic remission (SR), according to international criteria.

Herbaceous plant species invading natural areas tend to have stronger adaptive root foraging than other naturalized species.

Although plastic root-foraging responses are thought to be adaptive, as they may optimize nutrient capture of plants, this has rarely been tested. We investigated whether nutrient-foraging responses are adaptive, and whether they pre-adapt alien species to become natural-area invaders. We grew 12 pairs of congeneric species (i.

PET in the management of locally advanced and metastatic NSCLC.

Despite considerable improvements in the treatment options for advanced-stage non-small-cell lung cancer (NSCLC), disease-specific survival remains poor. With the aim of improving patient outcome, the treatment paradigm of locally advanced NSCLC has shifted from solely radiotherapy towards combined and intensified treatment approaches. Also, treatment for patients with stage IV (oligo)metastatic NSCLC has evolved rapidly, with therapeutic options that include a number of targeted agents, surgery, and stereotactic ablative radiotherapy.

Scleral lens influence on corneal curvature and pachymetry in keratoconus patients.

Objectives: To investigate the influence of full scleral lenses on corneal curvature and pachymetry in keratoconus patients.

Methods: In this intervention study, 20 eyes of 14 patients were measured by Scheimpflug imaging (Pentacam HR, Oculus) at two time points: directly and ≥1 week after scleral lens removal. Steep, flat and maximal keratometry (K(steep), K(flat) and K(max)) and optical pachymetry were analyzed.

The greening after extended darkness1 is an N-end rule pathway mutant with high tolerance to submergence and starvation.

Plants respond to reductions in internal oxygen concentrations with adaptive mechanisms (for example, modifications of metabolism to cope with reduced supply of ATP). These responses are, at the transcriptional level, mediated by the group VII Ethylene Response Factor transcription factors, which have stability that is regulated by the N-end rule pathway of protein degradation. N-end rule pathway mutants are characterized by a constitutive expression of hypoxia response genes and abscisic acid hypersensitivity.

Increased enzymatic hydrolysis of sugarcane bagasse from enzyme recycling.

Background: Development of efficient methods for production of renewable fuels from lignocellulosic biomass is necessary to maximize yields and reduce operating costs. One of the main challenges to industrial application of the lignocellulosic conversion process is the high costs of cellulolytic enzymes. Recycling of enzymes may present a potential solution to alleviate this problem.

White matter microstructure in chronic moderate-to-severe traumatic brain injury: Impact of acute-phase injury-related variables and associations with outcome measures.

This study examines how injury mechanisms and early neuroimaging and clinical measures impact white matter (WM) fractional anisotropy (FA), mean diffusivity (MD), and tract volumes in the chronic phase of traumatic brain injury (TBI) and how WM integrity in the chronic phase is associated with different outcome measures obtained at the same time. Diffusion tensor imaging (DTI) at 3 T was acquired more than 1 year after TBI in 49 moderate-to-severe-TBI survivors and 50 matched controls. DTI data were analyzed with tract-based spatial statistics and automated tractography.

Scleral lens tolerance after corneal cross-linking for keratoconus.

Purpose: Subjective and objective evaluation of scleral lens tolerance and fitting before and after corneal cross-linking (CXL) for progressive keratoconus.

Methods: In this prospective cohort, evaluations were made of 18 unilateral eyes in patients who underwent CXL and had been wearing scleral lenses before the procedure. All the patients gave informed consent; they were able to cooperate with the study, were eligible for CXL, had been wearing well-fitting scleral lenses for at least 3 months, and had no other active ocular disease.

Shade affects responses to drought and flooding - acclimation to multiple stresses in bittersweet (Solanum dulcamara L.).

Plants exposed to environmental stress often respond by a change in their phenotypic traits. These changes in trait expression may alleviate the negative effect of such stress factors. However, if multiple stresses are present, responses are likely to be less predictable and hence do not necessarily correlate to plant performance.

Cognitive shifting and externalising problem behaviour in intellectual disability and autism spectrum disorder.

Background: Behavioural problems are frequently reported in residential care for people with an intellectual disability (ID) in particular when they are additionally diagnosed with autism spectrum disorder (ASD). There are indications that impairment in cognitive shifting may be associated with problem behaviour. The objectives of this study were (1) to examine the relationship of cognitive shifting and severity of ASD symptoms with externalising problem behaviour in individuals with ID, with and without ASD, and (2) to examine whether a diagnosis based on shifting impairment is more predictive of externalising problem behaviour than an ASD diagnosis.

Muscle Activity during Walking Measured Using 3D MRI Segmentations and [18F]-Fluorodeoxyglucose in Combination with Positron Emission Tomography.

Purpose: This study aimed to determine the contribution of each muscle of the lower limb to walking using positron emission tomography (PET) with [F]-fluorodeoxyglucose (FDG). Furthermore, we compared our results obtained using volumetric analysis of entire muscles with those obtained using a more traditional approach considering the uptake in only one slice in each segment.

Methods: Ten healthy subjects walked on a treadmill at self-selected comfortable walking speed for 90 min, 60 min before and 30 min after intravenous injection of 50-MBq FDG.

Active encouragement of older women with urinary incontinence in primary care to undergo diagnosis and treatment: a matched-pair cluster randomized controlled trial.

Objectives: The URINO trial investigated the effect of offering treatment to older women with urinary incontinence in the general population, who had not sought help on their own initiative.

Study Design: In a cluster randomized trial, 14 general practitioners were matched into pairs and randomly allocated to an intervention or a control group. Women aged ≥ 55 years registered in the participating practices were asked about urinary incontinence via a postal questionnaire.

Chronic Widespread Pain Drawn on a Body Diagram is a Screening Tool for Increased Pain Sensitization, Psycho-Social Load, and Utilization of Pain Management Strategies.

The aim of this study was to investigate the hypothesis that chronic widespread pain, (CWP) drawn by patients on a body diagram, could be used as a screening tool for increased pain sensitization, psycho-social load, and utilization of pain management strategies. The triage questionnaires of 144 adults attending a chronic pain outpatients' clinic were audited and the percentage pain surface area (PPSA) drawn on their body diagrams was calculated using the "rule of nines" (RON) method for burns area assessment. Outcomes were measured using the painDETECT Questionnaire (PD-Q) and other indices and compared using a nonrandomized, case-control method.

FDG PET/CT: EANM procedure guidelines for tumour imaging: version 2.0.

The purpose of these guidelines is to assist physicians in recommending, performing, interpreting and reporting the results of FDG PET/CT for oncological imaging of adult patients. PET is a quantitative imaging technique and therefore requires a common quality control (QC)/quality assurance (QA) procedure to maintain the accuracy and precision of quantitation. Repeatability and reproducibility are two essential requirements for any quantitative measurement and/or imaging biomarker.

The Psychosis Recent Onset GRoningen Survey (PROGR-S): defining dimensions and improving outcomes in early psychosis.

Psychotic disorders are among the most complex medical conditions. Longitudinal cohort studies may offer further insight into determinants of functional outcome after a psychotic episode. This paper describes the Psychosis Recent Onset in GRoningen Survey (PROGR-S) that currently contains data on 1076 early-episode patients with psychosis, including symptoms, personality, cognition, life events and other outcome determinants.

Comparison of a free-breathing CT and an expiratory breath-hold CT with regard to spatial alignment of amplitude-based respiratory-gated PET and CT images.

Unlabelled: Respiratory motion during PET has a significant effect on the quantification of radiotracer uptake in PET images. Even when respiratory motion is considered using PET gating techniques, inaccuracies in standardized uptake values can be caused by inappropriate attenuation correction due to a spatial mismatch between PET and CT. In this study, the effect of breath-hold CT imaging on the spatial match between CT and amplitude-based respiratory-gated PET images is investigated.

Uncovering the defence responses of Eucalyptus to pests and pathogens in the genomics age.

Long-lived tree species are subject to attack by various pests and pathogens during their lifetime. This problem is exacerbated by climate change, which may increase the host range for pathogens and extend the period of infestation by pests. Plant defences may involve preformed barriers or induced resistance mechanisms based on recognition of the invader, complex signalling cascades, hormone signalling, activation of transcription factors and production of pathogenesis-related (PR) proteins with direct antimicrobial or anti-insect activity.
