Arterial Effects of Canakinumab in Patients With Atherosclerosis and Type 2 Diabetes or Glucose Intolerance.

Background: Evidence suggests that interleukin (IL)-1β is important in the pathogenesis of atherosclerosis and its complications and that inhibiting IL-1β may favorably affect vascular disease progression.

Objectives: The goal of this study was to evaluate the effects of IL-1β inhibition with canakinumab versus placebo on arterial structure and function, determined by magnetic resonance imaging.

Methods: Patients (N = 189) with atherosclerotic disease and either type 2 diabetes mellitus or impaired glucose tolerance were randomized to receive placebo (n = 94) or canakinumab 150 mg monthly (n = 95) for 12 months.

Duplex detection of the Mycobacterium tuberculosis complex and medically important non-tuberculosis mycobacteria by real-time PCR based on the rnpB gene.

A duplex real-time PCR based on the rnpB gene was developed for Mycobacterium spp. The assay was specific for the Mycobacterium tuberculosis complex (MTB) and also detected all 19 tested species of non-tuberculous mycobacteria (NTM). The assay was evaluated on 404 clinical samples: 290 respiratory samples and 114 from tissue and other non-respiratory body sites.

Appendectomy and risk of Parkinson's disease: A nationwide cohort study with more than 10 years of follow-up.

Objectives: The appendix may be a key site for the initiation of Parkinson's disease (PD) pathology. We examined the hypothesis that appendectomy is associated with lower PD risk.

Methods: We used Danish medical and administrative registries to construct a cohort of all patients in Denmark with an operation code of appendectomy during 1980-2010 (n = 265,758) and a matched general population comparison cohort (n = 1,328,790).

Prevalence, severity, and predictors of symptoms of dumping and hypoglycemia after Roux-en-Y gastric bypass.

Background: Roux-en-Y gastric bypass (RYGB) results in pronounced weight loss in morbidly obese patients but may also cause adverse effects like early dumping and hypoglycemia. Prevalence data on these complications and their potential predictors are sparse.

Objective: To assess the prevalence and possible predictors of early dumping and hypoglycemia in a population-based cohort of RYGB patients.

Interspecific interactions and learning variability jointly drive geographic differences in mate preferences.

Co-occurrence of closely related species can cause behavioral interference in mating and increase hybridization risk. Theoretically, this could lead to the evolution of more species-specific mate preferences and sexual signaling traits. Alternatively, females can learn to reject heterospecific males, to avoid male sexual interference from closely related species.

Constipation and risk of Parkinson's disease: A Danish population-based cohort study.

Objectives: To examine long-term associations between constipation and Parkinson's disease (PD) in men and women, we conducted a population-based cohort study using prospectively collected registry data on hospital contacts for constipation and PD, stratified by follow-up time and sex.

Methods: We linked Danish registries to construct a cohort of all patients in Denmark with an outpatient hospital diagnosis of constipation 1995-2012 and a matched general population comparison cohort. Using Cox regression, we computed hazard ratios (HRs) for PD and corresponding 95% confidence intervals (CIs), adjusting for potential confounders, stratified by sex and follow-up time.

The mitogenome of a 35,000-year-old Homo sapiens from Europe supports a Palaeolithic back-migration to Africa.

After the dispersal of modern humans (Homo sapiens) Out of Africa, hominins with a similar morphology to that of present-day humans initiated the gradual demographic expansion into Eurasia. The mitogenome (33-fold coverage) of the Peştera Muierii 1 individual (PM1) from Romania (35 ky cal BP) we present in this article corresponds fully to Homo sapiens, whilst exhibiting a mosaic of morphological features related to both modern humans and Neandertals. We have identified the PM1 mitogenome as a basal haplogroup U6*, not previously found in any ancient or present-day humans.

Linking intra- and interspecific assortative mating: Consequences for asymmetric sexual isolation.

Assortative mating is of interest because of its role in speciation and the maintenance of species boundaries. However, we know little about how within-species assortment is related to interspecific sexual isolation. Most previous studies of assortative mating have focused on a single trait in males and females, rather than utilizing multivariate trait information.

Occupational Tuberculosis in Denmark through 21 Years Analysed by Nationwide Genotyping.

Tuberculosis (TB) is a well-known occupational hazard. Based on more than two decades (1992-2012) of centralized nationwide genotyping of all Mycobacterium tuberculosis culture-positive TB patients in Denmark, we compared M. tuberculosis genotypes from all cases notified as presumed occupational (N = 130) with M.

The ETS1 transcription factor is required for the development and cytokine-induced expansion of ILC2.

Group 2 innate lymphoid cells (ILC2s) are a subset of ILCs that play a protective role in the response to helminth infection, but they also contribute to allergic lung inflammation. Here, we report that the deletion of the ETS1 transcription factor in lymphoid cells resulted in a loss of ILC2s in the bone marrow and lymph nodes and that ETS1 promotes the fitness of the common progenitor of all ILCs. ETS1-deficient ILC2 progenitors failed to up-regulate messenger RNA for the E protein transcription factor inhibitor ID2, a critical factor for ILCs, and these cells were unable to expand in cytokine-driven in vitro cultures.

Immunostimulatory AdCD40L gene therapy combined with low-dose cyclophosphamide in metastatic melanoma patients.

Background: Current approaches for treating metastatic malignant melanoma (MM) are not effective enough and are associated with serious adverse events. Due to its immunogenicity, melanoma is an attractive target for immunostimulating therapy. In this phase I/IIa study, local AdCD40L immunostimulatory gene therapy was evaluated in patients with MM.

Tailoring Charge Recombination in Photoelectrodes Using Oxide Nanostructures.

Optimizing semiconductor devices for solar energy conversion requires an explicit control of the recombination of photogenerated electron-hole pairs. Here we show how the recombination of charge carriers can be controlled in semiconductor thin films by surface patterning with oxide nanodisks. The control mechanism relies on the formation of dipole-like electric fields at the interface that, depending on the field direction, attract or repel minority carriers from underneath the disks.

Population pharmacokinetic drug-drug interaction pooled analysis of existing data for rifabutin and HIV PIs.

Objectives: Extensive but fragmented data from existing studies were used to describe the drug-drug interaction between rifabutin and HIV PIs and predict doses achieving recommended therapeutic exposure for rifabutin in patients with HIV-associated TB, with concurrently administered PIs.

Methods: Individual-level data from 13 published studies were pooled and a population analysis approach was used to develop a pharmacokinetic model for rifabutin, its main active metabolite 25-O-desacetyl rifabutin (des-rifabutin) and drug-drug interaction with PIs in healthy volunteers and patients who had HIV and TB (TB/HIV).

Results: Key parameters of rifabutin affected by drug-drug interaction in TB/HIV were clearance to routes other than des-rifabutin (reduced by 76%-100%), formation of the metabolite (increased by 224% in patients), volume of distribution (increased by 606%) and distribution to the peripheral compartment (reduced by 47%).

Gene expression under thermal stress varies across a geographical range expansion front.

Many ectothermic species are currently expanding their distributions polewards due to anthropogenic global warming. Molecular genetic mechanisms facilitating range expansion under these conditions are largely unknown, but understanding these could help mitigate expanding pests and disease vectors, or help explain why some species fail to track changing climates. Here, using RNA-seq data, we examine genomewide changes in gene expression under heat and cold stress in the range-expanding damselfly Ischnura elegans in northern Europe.

Evaluation of two instruments of perceived symptom intensity in palliative care patients in an outpatient clinic.

Aims And Objectives: To evaluate the test-retest stability in assessments of perceived symptom intensity on the Edmonton Symptom Assessment System-revised and the European Organization for Research and Treatment of Cancer, Quality of Life Questionnaire Core 15 Palliative. The possible interchangeability between the instruments and the patients' experiences of completing the instruments were also studied.

Background: The two instruments assess the same symptoms, but the symptom intensity is assessed on 11-point numerical scales on the Edmonton Symptom Assessment System-revised and on four-point verbal descriptive scales on the European Organization for Research and Treatment of Cancer, Quality of Life Questionnaire Core 15 Palliative.

Vitamin D levels and depressive symptoms in patients with chronic heart failure.

Background: Vitamin D (Vit D) is suggested to play a role in the regulation of physical function as well as in depression. Since, Vit D deficiency is common in patients with heart failure (HF), this study aims to explore if Vit D levels are associated with depressive symptoms and if this association is mediated by the patients' physical function.

Method: 506 HF patients (mean age 71, 38% women) were investigated.

Repetition priming-induced changes in sensorimotor transmission.

When a behavior is repeated performance often improves, i.e., repetition priming occurs.

Adjustment disorder and risk of Parkinson's disease.

Background And Purpose: It has been postulated that stress is part of the etiological process of Parkinson's disease (PD). The risk of PD was examined in a cohort of patients with adjustment disorders, a diagnosis made in the presence of a severe response to a stressful life event.

Methods: Using Danish medical registries, PD occurrence was examined in a nationwide population-based cohort of patients with adjustment disorder diagnosed between 1995 and 2011.

Genomic Evidence Establishes Anatolia as the Source of the European Neolithic Gene Pool.

Anatolia and the Near East have long been recognized as the epicenter of the Neolithic expansion through archaeological evidence. Recent archaeogenetic studies on Neolithic European human remains have shown that the Neolithic expansion in Europe was driven westward and northward by migration from a supposed Near Eastern origin [1-5]. However, this expansion and the establishment of numerous culture complexes in the Aegean and Balkans did not occur until 8,500 before present (BP), over 2,000 years after the initial settlements in the Neolithic core area [6-9].

Prevalence of Self-reported Symptoms After Gastric Bypass Surgery for Obesity.

Importance: Population-based studies on the prevalence of symptoms after Roux-en-Y gastric bypass (RYGB) surgery are sparse. Knowledge about possible predictors of these symptoms is important for prevention.

Objectives: To examine patients' overall well-being and the prevalence and predictors of medical, nutritional, and surgical symptoms after RYGB surgery, and their association with quality of life.

Factors Controlling the Stable Nitrogen Isotopic Composition (δ15N) of Lipids in Marine Animals.

Lipid extraction of biomass prior to stable isotope analysis is known to cause variable changes in the stable nitrogen isotopic composition (δ15N) of residual biomass. However, the underlying factors causing these changes are not yet clear. Here we address this issue by comparing the δ15N of bulk and residual biomass of several marine animal tissues (fish, crab, cockle, oyster, and polychaete), as well as the δ15N of the extracted lipids.

Evaluation of Intracellular Signaling Downstream Chimeric Antigen Receptors.

CD19-targeting CAR T cells have shown potency in clinical trials targeting B cell leukemia. Although mainly second generation (2G) CARs carrying CD28 or 4-1BB have been investigated in patients, preclinical studies suggest that third generation (3G) CARs with both CD28 and 4-1BB have enhanced capacity. However, little is known about the intracellular signaling pathways downstream of CARs.

Associations between stress disorders and cardiovascular disease events in the Danish population.

Objectives: Post-traumatic stress disorder (PTSD) is a well-documented risk factor for cardiovascular disease (CVD). However, it is unknown whether another common stress disorder-adjustment disorder--is also associated with an increased risk of CVD and whether gender modifies these associations. The aim of this study was to examine the overall and gender-stratified associations between PTSD and adjustment disorder and 4 CVD events.

The Associations Between Pre- and Postnatal Maternal Symptoms of Distress and Preschooler's Symptoms of ADHD, Oppositional Defiant Disorder, Conduct Disorder, and Anxiety.

The objective of this article is to examine the associations between pre- and postnatal maternal distress and preschooler's symptoms of ADHD, Oppositional Defiant Disorder (ODD), Conduct Disorder (CD), and anxiety, by timing and gender. Children, aged 3.5 years ( = 1,195), recruited from the Norwegian Mother and Child Cohort Study, were assessed with a semistructured parental psychiatric interview.

Compound-specific stable isotope analysis of nitrogen-containing intact polar lipids.

Rationale: Compound-specific isotope analysis (CSIA) of nitrogen in amino acids has proven a valuable tool in many fields (e.g. ecology).
