Interactions of neutrophils with endothelial cells (ECs) and platelets contribute to tissue damage and vascular occlusion under sterile inflammatory conditions. However, the molecular mechanisms regulating the cell-cell interactions remain poorly understood. Previous studies suggest that reactive oxygen species, such as hydrogen peroxide (H2 O2 ), produced from NADPH oxidase 2 play a critical role in platelet-neutrophil interactions by regulating the function of neutrophil αMβ2 integrin during sterile inflammation...

Among an estimated 850,000 to 2.2 million persons with chronic hepatitis B virus (HBV) infection in the United States, 70% are non-U.S.-born (1,2). All patients require linkage to care, and approximately 20%-40% require antiviral treatment (3). Without treatment, one in four persons chronically infected with HBV will die prematurely from liver failure, liver cirrhosis, or hepatocellular carcinoma (4). To mitigate morbidity and mortality, CDC funded a cooperative agreement to develop hepatitis B testing and linkage-to-care programs serving non-U...

Three recent studies have documented short- and long-run benefits of early-infancy health interventions in Norway, Sweden, and Denmark: Universal nurse home visiting (NHV) and well-baby center care decreased infant mortality and positively impacted long-run survival (DK, S), morbidity (DK, N), and educational and labor market outcomes (N). Using Danish conscription data, this paper examines intermediate outcomes to assess both potential mechanisms and the importance of selective survival for the long-run health effects of NHV...

Upon the pathogen encounter, the host seeks to ensure an adequate inflammatory reaction to combat infection but at the same time tries to prevent collateral damage, through several regulatory mechanisms, like an endocrine response involving the production of adrenal steroid hormones. Our studies show that active tuberculosis (TB) patients present an immune-endocrine imbalance characterized by an impaired cellular immunity together with increased plasma levels of cortisol, pro-inflammatory cytokines, and decreased amounts of dehydroepiandrosterone...

In this article, we show how to use administrative data from the Matrícula Consular de Alta Seguridad (MCAS) identification card program to measure the joint distribution of sending and receiving locations for migrants from Mexico to the United States. Whereas other data sources cover only a small fraction of source or destination locations or include only very coarse geographic information, the MCAS data provide complete geographic coverage of both countries, detailed information on migrants' sources and destinations, and a very large sample size...

BACKGROUND: Physician migration has been gaining attention worldwide. In Germany, physician migration became a topic of interest in the context of the discussion about a shortage of physicians, for which one contributing factor may be physicians leaving the country. However, there is a lack of literature on "push" factors causing German physicians to leave. The present study seeks to provide current data in an effort to promote the identification of "push" factors motivating German physicians to emigrate...

OBJECTIVES: To investigate mortality and its predictors in a retrospectively defined population-based rheumatoid arthritis (RA) inception cohort Method: We included patients ascertained with incident RA from a region in the southern part of Denmark from 1995 to 2002. All patients fulfilled the 1987 American College of Rheumatology criteria for RA. The patients were followed from RA classification until death, emigration, or end of follow-up on 31 December 2013. We used personal record linkage with national public registers to obtain information on education, employment, cohabitation, comorbidity, and vital status...

Premature aging of both CD4+ -regulatory- (Tregs) and CD4+ -responder-T-cells (Tresps) in end-stage renal disease (ESRD) patients is expected to affect the success of later kidney transplantation. Both T-cell populations are released from the thymus as inducible co-stimulatory (ICOS+ -) and ICOS- -recent thymic emigrant (RTE)-Tregs/Tresps, which differ primarily in their proliferative capacities. In this study, we analysed the effect of ESRD and subsequent renal replacement therapies on the differentiation of ICOS+ - and ICOS- -RTE-Tregs/Tresps into ICOS+ - or ICOS- -CD31- -Memory-Tregs/Tresps and examined whether diverging pathways affected the suppressive activity of ICOS+ - and ICOS- -Tregs in co-culture with autologous Tresps...

Many studies have found that health outcomes decline when health professionals leave the country, but do such results remain consistent in gender- and income-disaggregated skilled migration? To help uncover explanations for such a pro-migration nature of health outcomes, the present study revisits this topic but allows for associations of skilled migration with mortality and life expectancy to differ between male and female, and between low- and high-income countries. Using a panel of 133 developing countries as source and 20 OECD countries as destination from 1980 to 2010 allowing the coefficient on emigration across different education levels to differ, the study finds the negative effect of high-skilled emigration on health outcomes...

Plant sap feeding insects like psyllids are known to be vectors of phloem dwelling bacteria (' Candidatus Phytoplasma' and ' Ca . Liberibacter'), plant pathogens which cause severe diseases and economically important crop damage. Some univoltine psyllid species have a particular life cycle, within one generation they alternate two times between different host plant species. The plum psyllid Cacopsylla pruni , the vector of European Stone Fruit Yellows (ESFY), one of the most serious pests in European fruit production, migrates to stone fruit orchards ( Prunus spp...

Plant species tend to retain their ancestral ecology, responding to temporal, geographic and climatic changes by tracking suitable habitats rather than adapting to novel conditions. Nevertheless, transitions into different environments or biomes still seem to be common. Especially intriguing are the tropical alpine-like areas found on only the highest mountainous regions surrounded by tropical environments. Tropical mountains are hotspots of biodiversity, often with striking degrees of endemism at higher elevations...

The diaphragm is a mammalian skeletal muscle essential for respiration and for separating the thoracic and abdominal cavities. Development of the diaphragm requires the coordinated development of muscle, muscle connective tissue, tendon, nerves, and vasculature that derive from different embryonic sources. However, defects in diaphragm development are common and the cause of an often deadly birth defect, Congenital Diaphragmatic Hernia (CDH). Here we comprehensively describe the normal developmental origin and complex spatial-temporal relationship between the different developing tissues to form a functional diaphragm using a developmental series of mouse embryos genetically and immunofluorescently labeled and analyzed in whole mount...

Allee effects are defined as a decline in per capita fitness at low population density. We hypothesized that predation reduces population size of breeding waders and thereby the efficiency of predator deterrence, while total nitrogen through its effects on primary and secondary productivity increases population size. Therefore, nest predation could have negative consequences for population size because nest failure generally results in breeding dispersal and hence reduced local population density. To test these predictions we recorded nest predation in five species of waders for 4745 nests during 1987-2015 at the nature reserve Tipperne, Denmark...

AIMS: Fingolimod, an orally active immunomodulatory drug for relapsing-remitting multiple sclerosis (RRMS), sequesters T cells in lymph nodes through functional antagonism of the sphingosine-1-phosphate receptor, reducing the number of potential autoreactive cells that migrate to the central nervous system. However, not all RRMS patients respond to this therapy. Our aim was to test the hypothesis that by immune-monitoring RRMS patient's leukocyte subpopulations it is possible to find biomarkers associated with clinical response to fingolimod...

Reports on pulmonary hypertension (PH) in the aging congenital heart disease (CHD) population are few and focused on arterial PH and patients with systemic-to-pulmonary shunts. Our objective was to estimate incidence and mortality of adult-onset PH in the CHD population. Using Danish nationwide registries, we identified all patients diagnosed with CHD from 1963 to 1974 and 1977 to 2012. Patients were matched 1:10 by birth year and gender with general population subjects. Between 1977 and 2013 adults >18 years of age were followed up until PH diagnosis, death, or emigration, whichever came first, using data from the Danish National Registry of Patients...

Macrophages play critical roles in renal fibrosis. However, macrophages exhibit ontogenic and functional heterogeneities, and which population of macrophages contributes to renal fibrosis and the underlying mechanisms remain unclear. In this study, we genetically targeted Notch signaling by disrupting the transcription factor recombination signal binding protein-Jκ (RBP-J), to reveal its role in regulation of macrophages during the unilateral ureteral obstruction (UUO)-induced murine renal fibrosis. Myeloid-specific disruption of RBP-J attenuated renal fibrosis with reduced extracellular matrix deposition and myofibroblast activation, as well as attenuated epithelial-mesenchymal transition, likely owing to the reduced expression of TGF-β...

INTRODUCTION: High urate levels have consistently been associated with lower Parkinson's disease (PD) risk among men, but the association is less clear among women. In this study we prospectively investigated the association between high uric acid levels and PD, evaluating potential differences by sex and age. METHODS: This historical cohort study included the entire Norwegian population alive and at least 18 years old on 01/01/2004. We retrieved use of urate-lowering drugs, a marker of high urate levels/gout, from the Norwegian Prescription Database, and followed individuals from 01/01/2005 to PD onset, emigration, death, or end of follow-up on 31/12/2013...
