- OBJECTIVES:To report the initial experience of an international group of investigators in identifying mutations in the BRCA1 breast and ovarian cancer susceptibility gene, to assess the spectrum of such mutations in samples from patients with different family histories of cancer, and to determine the frequency of recurrent mutations.DESIGN:Nine laboratories in North America and the United Kingdom tested for BRCA1 mutations in DNA samples obtained from a total of 372 unrelated patients with breast or ovarian cancer largely chosen from high-risk families. Three of these laboratories also analyzed a total of 714 additional samples from breast or ovarian cancer cases, including 557 unselected for family history, for two specific mutations that had been found to recur in familial samples.PARTICIPANTS:A total of 1086 women with either breast or ovarian cancer.MAIN OUTCOME MEASURE:The detection of sequence variation in patients' DNA samples that is not found in sets of control samples.RESULTS:BRCA1 mutations have now been identified in a total of 80 patient samples. Thirty-eight distinct mutations were found among 63 mutations identified through a complete screen of the BRCA1 gene. Three specific mutations appeared relatively common, occurring eight, seven, and five times, respectively. When specific tests for the two most common mutations were performed in larger sets of samples, they were found in 17 additional patients. Mutations predicted to result in a truncated protein accounted for 86% of the mutations detected by complete screening.CONCLUSIONS:The high frequency of protein-terminating mutations and the observation of many recurrent mutations found in a diverse set of samples could lead to a relatively simple diagnostic test for BRCA1 mutations. More data must be accumulated to address specifically the sensitivity and specificity of such a diagnostic testing procedure and to better estimate the age-specific risk for breast and ovarian cancer associated with such mutations.

Usage of bioinformatics tools and identification of information sources
- 2005
-
Reports (other academic/artistic)abstract
- Bioinformatics is an important application area for semantic web technologies as much of the data is online and accessible in XML format, as some sites already support web services, and as ontologies are widely used to annotate data. In this deliverable, we give a survey over 18 of the most important bioinformatics resources and discuss their availability and accessibility, which are two of the main criteria for these resources to act as bases for later demonstrators.

- Interventions based on Cognitive Behavioral Therapy (CBT) are widely used to treat chronic pain, but the brain mechanisms responsible for these treatment effects are poorly understood. The aim of this study was to validate the relevance of the cortical control theory in response to an exposure-based form of CBT, Acceptance and Commitment Therapy, in patients with chronic pain. Forty-three female patients diagnosed with fibromyalgia syndrome were enrolled in a randomized, 12-week, waiting-list controlled clinical trial (CBT n=25; controls n=18). CBT was administered in groups of six patients during 12 weekly sessions. Functional magnetic resonance imaging (fMRI) during pressure-evoked pain was assessed before and after treatment or the 12-week period. Self-report questionnaires of depression and anxiety were administered pre- and posttreatment as well as 3 months following end of treatment. Patients treated with CBT reported larger improvement of fibromyalgia on the Patient Global Impression of Change measure, and improved depression and anxiety symptoms, compared to the waiting-list controls. However, there were no effects on clinical pain or pain sensitivity measures. An analysis of fMRI scans revealed that CBT led to increased activations in the ventrolateral prefrontal/lateral orbitofrontal cortex; regions associated with executive cognitive control. We suggest that CBT changes the brain's processing of pain through an altered cerebral loop between pain signals, emotions, and cognitions; leading to increased access to executive regions for reappraisal of pain. Our data thereby support our hypothesis about the activation of a cortical control mechanism in response to CBT treatment in chronic pain.

Desert crossing strategies of migrant songbirds vary between and within species
- 2019

Journal article (peer-reviewed)abstract
- Each year, billions of songbirds cross large ecological barriers during their migration. Understanding how they perform this incredible task is crucial to predict how global change may threaten the safety of such journeys. Earlier studies based on radar suggested that most songbirds cross deserts in intermittent flights at high altitude, stopping in the desert during the day, while recent tracking with light loggers suggested diurnal prolongation of nocturnal flights and common non-stop flights for some species. We analyzed light intensity and temperature data obtained from geolocation loggers deployed on 130 individuals of ten migratory songbird species, and show that a large variety of strategies for crossing deserts exists between, but also sometimes within species. Diurnal stopover in the desert is a common strategy in autumn, while most species prolonged some nocturnal flights into the day. Nonstop flights over the desert occurred more frequently in spring than in autumn, and more frequently in foliage gleaners. Temperature recordings suggest that songbirds crossed deserts with flight bouts performed at various altitudes according to species and season, along a gradient ranging from low above ground in autumn to probably >2000 m above ground level, and possibly at higher altitude in spring. High-altitude flights are therefore not the general rule for crossing deserts in migrant songbirds. We conclude that a diversity of migration strategies exists for desert crossing among songbirds, with variations between but also within species.

Patients with ME/CFS (Myalgic Encephalomyelitis/Chronic Fatigue Syndrome) and chronic pain report similar level of sickness behavior as individuals injected with bacterial endotoxin at peak inflammation
- 2020

In: Brain, Behavior, & Immunity - Health. - : Elsevier BV. - 2666-3546. ; 2

Journal article (peer-reviewed)abstract
- Background: Chronic sickness behavior is implicated in ME/CFS (Myalgic Encephalomyelitis/Chronic Fatigue Syndrome) and chronic pain but the level of subjective sickness behavior in these conditions has not been investigated or compared to other clinical and non-clinical samples, or to the level in experimental inflammation. Furthermore, the relationship between sickness behavior and self-rated health and functioning is not known in patients with ME/CFS and chronic pain. The aim of the present study was to investigate how sickness behavior in patients with chronic conditions differs from that in individuals with experimental acute sickness, primary care patients, the general population and healthy subjects. In addition, we wanted to explore how sickness behavior is related to self-rated health and health-related functioning.Methods: Sickness behavior was quantified using the sickness questionnaire (SicknessQ). Self-ratings were collected at one time-point in 6 different samples. Levels of sickness behavior in patients with ME/CFS (n = 38) and patients with chronic pain (n = 190) were compared to healthy subjects with lipopolysaccharide(LPS)-induced inflammation (n = 29), primary care patients (n = 163), individuals from the general population (n = 155) and healthy subjects (n = 48), using linear regression. Correlations and moderated regression analyses were used to investigate associations between sickness behavior and self-rated health and health-related functioning in ME/CFS, chronic pain and the general population.Results: LPS-injected individuals (M = 16.3), patients with ME/CFS (M = 16.1), chronic pain (M = 16.1) and primary care patients (M = 10.7) reported significantly higher SicknessQ scores than individuals from the general population (M = 5.4) and healthy subjects (M = 3.6) all p’s < 0.001). In turn, LPS-injected individuals, patients with ME/CFS and chronic pain reported significantly higher SicknessQ scores than primary care patients (p’s < 0.01). Higher levels of sickness behavior were associated with poorer self-rated health and health-related functioning (p’s < 0.01), but less so in patients with ME/CFS and chronic pain than in individuals from the general population.Conclusions: Patients with ME/CFS and chronic pain report similar high levels of sickness behavior; higher than primary care patients, and comparable to levels in experimental inflammation. Further study of sickness behavior in ME/CFS and chronic pain populations is warranted as immune-to-brain interactions and sickness behavior may be of importance for functioning as well as in core pathophysiological processes in subsets of patients.

Substantial Heritable Variation in Recombination Rate on Multiple Scales in Honeybees and Bumblebees
- 2019

Journal article (peer-reviewed)abstract
- Meiotic recombination shuffles genetic variation and promotes correct segregation of chromosomes. Rates of recombination vary on several scales, both within genomes and between individuals, and this variation is affected by both genetic and environmental factors. Social insects have extremely high rates of recombination, although the evolutionary causes of this are not known. Here, we estimate rates of crossovers and gene conversions in 22 colonies of the honeybee, Apis mellifera, and 9 colonies of the bumblebee, Bombus terrestris, using direct sequencing of 299 haploid drone offspring. We confirm that both species have extremely elevated crossover rates, with higher rates measured in the highly eusocial honeybee than the primitively social bumblebee. There are also significant differences in recombination rate between subspecies of honeybee. There is substantial variation in genome-wide recombination rate between individuals of both A. mellifera and B. terrestris and the distribution of these rates overlap between species. A large proportion of interindividual variation in recombination rate is heritable, which indicates the presence of variation in trans-acting factors that influence recombination genome-wide. We infer that levels of crossover interference are significantly lower in honeybees compared to bumblebees, which may be one mechanism that contributes to higher recombination rates in honeybees. We also find a significant increase in recombination rate with distance from the centromere, mirrored by methylation differences. We detect a strong transmission bias due to GC-biased gene conversion associated with noncrossover gene conversions. Our results shed light on the mechanistic causes of extreme rates of recombination in social insects and the genetic architecture of recombination rate variation.

Efficacy and Cost-effectiveness of Acceptance and Commitment Therapy and Applied Relaxation for Longstanding Pain : a Randomized Controlled Trial
- 2015
-
In: The Clinical Journal of Pain. - : Lippincott Williams & Wilkins. - 0749-8047 .- 1536-5409. ; 31:11, s. 1004-1016
-
Journal article (peer-reviewed)abstract
- Background and Objectives: To date, few studies have compared Acceptance and Commitment Therapy (ACT) for longstanding pain with established treatments. Only 1 study has evaluated the cost-effectiveness of ACT. The aim of the current study was to evaluate the efficacy and cost-effectiveness of ACT and applied relaxation (AR) for adults with unspecific, longstanding pain.Materials and Methods: On the basis of the inclusion criteria 60 consecutive patients received 12 weekly group sessions of ACT or AR. Data were collected pretreatment, midtreatment, and posttreatment, as well as at 3- and 6-month follow-up. Growth curve modeling was used to analyze treatment effects on pain disability, pain intensity, health-related quality of life (physical domain), anxiety, depression, and acceptance.Results: Significant improvements were seen across conditions (pretreatment to follow-up assessment) on all outcome measures. Pain disability decreased significantly in ACT relative to AR from preassessment to postassessment. A corresponding decrease in pain disability was seen in AR between postassessment and 6-month follow-up. Pain acceptance increased only in ACT, and this effect was maintained at 6-month follow-up. Approximately 20% of the participants achieved clinically significant change after treatment. Health economic analyses showed that ACT was more cost-effective than AR at post and 3-month follow-up assessment, but not at 6-month follow-up.Discussion: More studies investigating moderators and mediators of change are needed. The present study is one of few that have evaluated the cost-effectiveness of ACT and AR and compared ACT with an established behavioral intervention, and the results provide additional support for behavioral interventions for longstanding pain.

Global phenological insensitivity to shifting ocean temperatures among seabirds

Journal article (peer-reviewed)abstract
- Reproductive timing in many taxa plays a key role in determining breeding productivity(1), and is often sensitive to climatic conditions(2). Current climate change may alter the timing of breeding at different rates across trophic levels, potentially resulting in temporal mismatch between the resource requirements of predators and their prey(3). This is of particular concern for higher-trophic-level organisms, whose longer generation times confer a lower rate of evolutionary rescue than primary producers or consumers(4). However, the disconnection between studies of ecological change in marine systems makes it difficult to detect general changes in the timing of reproduction(5). Here, we use a comprehensive meta-analysis of 209 phenological time series from 145 breeding populations to show that, on average, seabird populations worldwide have not adjusted their breeding seasons over time (-0.020 days yr(-1)) or in response to sea surface temperature (SST) (-0.272 days degrees C-1) between 1952 and 2015. However, marked between-year variation in timing observed in resident species and some Pelecaniformes and Suliformes (cormorants, gannets and boobies) may imply that timing, in some cases, is affected by unmeasured environmental conditions. This limited temperature-mediated plasticity of reproductive timing in seabirds potentially makes these top predators highly vulnerable to future mismatch with lower-trophic-level resources(2).
