Database of diazotrophs in global ocean : abundance, biomass and nitrogen fixation rates
- 2012

Journal article (peer-reviewed)abstract
- Marine N-2 fixing microorganisms, termed di-azotrophs, are a key functional group in marine pelagic ecosystems. The biological fixation of dinitrogen ( N-2) to bioavailable nitrogen provides an important new source of nitrogen for pelagic marine ecosystems and influences primary productivity and organic matter export to the deep ocean. As one of a series of efforts to collect biomass and rates specific to different phytoplankton functional groups, we have constructed a database on diazotrophic organisms in the global pelagic upper ocean by compiling about 12 000 direct field measurements of cyanobacterial diazotroph abundances (based on microscopic cell counts or qPCR assays targeting the nifH genes) and N-2 fixation rates. Biomass conversion factors are estimated based on cell sizes to convert abundance data to diazotrophic biomass. The database is limited spatially, lacking large regions of the ocean especially in the Indian Ocean. The data are approximately log-normal distributed, and large variances exist in most sub-databases with non-zero values differing 5 to 8 orders of magnitude. Reporting the geometric mean and the range of one geometric standard error below and above the geometric mean, the pelagic N-2 fixation rate in the global ocean is estimated to be 62 (52-73) Tg Nyr(-1) and the pelagic diazotrophic biomass in the global ocean is estimated to be 2.1 (1.4-3.1) Tg C from cell counts and to 89 (43-150) Tg C from nifH- based abundances. Reporting the arithmetic mean and one standard error instead, these three global estimates are 140 +/- 9.2 Tg Nyr(-1), 18 +/- 1.8 Tg C and 590 +/- 70 Tg C, respectively. Uncertainties related to biomass conversion factors can change the estimate of geometric mean pelagic diazotrophic biomass in the global ocean by about +/- 70 %. It was recently established that the most commonly applied method used to measure N-2 fixation has underestimated the true rates. As a result, one can expect that future rate measurements will shift the mean N-2 fixation rate upward and may result in significantly higher estimates for the global N-2 fixation. The evolving database can nevertheless be used to study spatial and temporal distributions and variations of marine N-2 fixation, to validate geochemical estimates and to parameterize and validate biogeochemical models, keeping in mind that future rate measurements may rise in the future.

- 2018
-
In: European journal of preventive cardiology. - : Oxford University Press (OUP). - 2047-4881 .- 2047-4873. ; 25:4, s. 377-387

Journal article (peer-reviewed)abstract
- Chronic ischaemic cardiovascular disease (CICD) remains a leading cause of morbidity and mortality worldwide. The CICD Pilot Registry enrolled 2420 patients across 10 European Society of Cardiology countries prospectively to describe characteristics, management strategies and clinical outcomes in this setting. We report here the six-month outcomes. Methods and results From the overall population, 2203 patients were analysed at six months. Fifty-eight patients (2.6%) died after inclusion; 522 patients (23.7%) experienced all-cause hospitalisation or death. The rate of prescription of angiotensin-converting enzyme inhibitors, beta-blockers and aspirin was mildly decreased at six months (all P < 0.02). Patients who experienced all-cause hospitalisation or death were older, more often had a history of non-ST-segment elevation myocardial infarction, of chronic kidney disease, peripheral revascularisation and/or chronic obstructive pulmonary disease than those without events. Independent predictors of all-cause mortality/hospitalisation were age (hazard ratio (HR) 1.17, 95% confidence interval (CI) 1.07–1.27) per 10 years, and a history of previous peripheral revascularisation (HR 1.45, 95% CI 1.03–2.03), chronic kidney disease (HR 1.31, 95% CI 1.0–1.68) or chronic obstructive pulmonary disease (HR 1.42, 95% CI 1.06–1.91, all P < 0.05). We observed a higher rate of events in eastern, western and northern countries compared to southern countries and in cohort 1. Conclusion In this contemporary European registry of CICD patients, the rate of severe clinical outcomes at six months was high and was influenced by age, heart rate and comorbidities. The medical management of this condition remains suboptimal, emphasising the need for larger registries with long-term follow-up. Ad-hoc programmes aimed at implementing guidelines adherence and follow-up procedures are necessary, in order to improve quality of care and patient outcomes.

Brachial pulse pressure in acute heart failure. Results of the Heart Failure Registry
- 2019
-
In: ESC Heart Failure. - : WILEY PERIODICALS, INC. - 2055-5822. ; 6:6, s. 1167-1177
-
Journal article (peer-reviewed)abstract
- Aims To investigate the still uncertain independent prognostic impact of pulse pressure (PP) in acute heart failure (HF), in particular across the left ventricular ejection fraction (EF) phenotypes, and the potential contribution of PP in outlining the individual phenotypes. Methods and results We prospectively evaluated 1-year death and rehospitalization in 4314 patients admitted for acute HF grouped by EF and stratified by their PP level on admission. In HF with reduced (amp;lt; 40%) EF (HFrEF), the highest quartiles of PP had the lowest unadjusted [hazard ratio (HR) 0.77, 95% confidence interval (CI) 0.61-0.98] and adjusted (HR 0.64 0.50-0.82) risk of 1 year all cause death compared to the lowest quartile. Its prognostic impact was partially mediated by systolic blood pressure (SBP). In HF with preserved (amp;gt;= 50%) EF (HFpEF), the intermediate quartile of PP showed the lowest 1 year all cause mortality in unadjusted (HR 0.598, CI 0.416-0.858) and adjusted (HR 0.55, 95% CI 0.388-0.801) models with no relationship with SBP. In a receiver operating characteristic analysis, a combination of PP amp;gt; 60 mmHg and SBP amp;gt; 140 mmHg was associated to a preserved EF with a high performance value. No prognostic significance of PP was found in the HF with mid-range EF subgroup. Conclusions In acute HFrEF, there is an almost linear inverse relation between mortality and PP, partly mediated by SBP. In HFpEF, a J-shaped relationship between mortality and PP was present with a better prognosis at the nadir. A combination of PP amp;gt; 60 mmHg with SBP amp;gt; 140 mmHg may be clinically helpful as marker of a preserved left ventricular EF.

- Physiological and genetic responses of age 0+ Platichthys flesus were investigated in the eutrophicated and moderately contaminated Vilaine estuary, during a 6-month survey. The main objective of this study was to explore the biological responses of fishes during their juvenile period in an estuarine system in order to detect a possible selective pressure induced by the environmental stress. Our results showed a general convergence in physiological responses along the survey: an increase in genotoxicity was associated with an increase in mRNA expression of ATPase and betaine homocysteine methyltransferase. These results could suggest an increase of cellular damage, energetic request, and detoxification rate related to the growing exposure time to stress. Considering the aging of the cohort, the genetic characteristics of the Vilaine flounder cohort came closer to the one observed in a highly stressed system, the Seine estuary, suggesting a potential selective pressure mainly induced by the chemical stress. © 2012 Springer-Verlag.

Journal article (peer-reviewed)abstract
- AIMS: Guidelines recommend down-titration of loop diuretics (LD) once euvolaemia is achieved. In outpatients with heart failure (HF), we investigated LD dose changes in daily cardiology practice, agreement with guideline recommendations, predictors of successful LD down-titration and association between dose changes and outcomes.METHODS AND RESULTS: We included 8130 HF patients from the ESC-EORP Heart Failure Long-Term Registry. Among patients who had dose decreased, successful decrease was defined as the decrease not followed by death, HF hospitalization, New York Heart Association class deterioration, or subsequent increase in LD dose. Mean age was 66 ± 13 years, 71% men, 62% HF with reduced ejection fraction, 19% HF with mid-range ejection fraction, 19% HF with preserved ejection fraction. Median [interquartile range (IQR)] LD dose was 40 (25-80) mg. LD dose was increased in 16%, decreased in 8.3% and unchanged in 76%. Median (IQR) follow-up was 372 (363-419) days. Diuretic dose increase (vs. no change) was associated with HF death [hazard ratio (HR) 1.53, 95% confidence interval (CI) 1.12-2.08; P = 0.008] and nominally with cardiovascular death (HR 1.25, 95% CI 0.96-1.63; P = 0.103). Decrease of diuretic dose (vs. no change) was associated with nominally lower HF (HR 0.59, 95% CI 0.33-1.07; P = 0.083) and cardiovascular mortality (HR 0.62, 95% CI 0.38-1.00; P = 0.052). Among patients who had LD dose decreased, systolic blood pressure [odds ratio (OR) 1.11 per 10 mmHg increase, 95% CI 1.01-1.22; P = 0.032], and absence of (i) sleep apnoea (OR 0.24, 95% CI 0.09-0.69; P = 0.008), (ii) peripheral congestion (OR 0.48, 95% CI 0.29-0.80; P = 0.005), and (iii) moderate/severe mitral regurgitation (OR 0.57, 95% CI 0.37-0.87; P = 0.008) were independently associated with successful decrease.CONCLUSION: Diuretic dose was unchanged in 76% and decreased in 8.3% of outpatients with chronic HF. LD dose increase was associated with worse outcomes, while the LD dose decrease group showed a trend for better outcomes compared with the no-change group. Higher systolic blood pressure, and absence of (i) sleep apnoea, (ii) peripheral congestion, and (iii) moderate/severe mitral regurgitation were independently associated with successful dose decrease.

Journal article (peer-reviewed)abstract
- To compare the prevalence rates of mental disorders among children of parents with bipolar disorder and of parents with no mental disorders.Method:Seventeen studies, meeting specific selection criteria, were included in the metaanalyses. Risks for mental disorders among children were estimated by aggregating raw data from the selected studies.Results:Results indicate that in comparison with children of parents with no mental disorders, children of parents with bipolar disorder are 2.7 times more likely to develop any mental disorder and 4.0 times more likely to develop an affective disorder. The metaanalyses indicate that during childhood and adolescence, the risks for any mental disorder and for affective disorders in children are consistently but moderately related to having a parent who suffers from bipolar disorder.Conclusions:Risk factors that could account for the psychopathology observed in children of bipolar parents are explored.

Accounting for trade in derived products when estimating European Union's role in driving deforestation
- 2024
-
In: Ecological Economics. - 0921-8009. ; 224
-
Journal article (peer-reviewed)abstract
- Governments across the world are increasingly seeking to ensure that the products consumed in their countries meet certain sustainability standards. However, the places of production—where major impacts occur—are often distant from the places of consumption. Physical trade models are suited to estimate the link between consumption and production impacts for individual commodities, but often ignore trade in derived products, obtained by processing primary commodities, especially for non-food products. Derived products which are manufactured using multiple primary commodities, such as shoes containing leather, rubber, as well as other textile materials, pose a special challenge for these models. This can lead to biased assessments of sustainability risks and obscure leverage points to address them. To mitigate the risk of bias, here we present an approach for assessing the importance of accounting for trade in derived products when attributing impacts. We apply the approach to trade in rubber and bovine hide products and associated deforestation to assess the coverage of relevant products included in the European Union (EU) regulation on deforestation-free products (EUDR), as well as to inform future revisions of the regulation's scope. We consider trade flows for 135 types of rubber products and 37 types of products derived from bovine hides. We find that rubber and bovine hides enter the EU at different stages of the supply chain. While natural rubber enters the EU at an early processing stage, through imports of raw natural rubber, most products derived from bovine hides enter the EU either as processed products or as consumer goods. Our results thus highlight that depending on the product, the share of total deforestation attributed to the EU's consumption could be significantly affected by choices in which derived products are accounted for. Weighting the costs and benefits of the inclusion of derived products for each commodity is therefore key to designing demand-side policies that cost-effectively and successfully address the deforestation risk associated with consumption.

Platelet EVs contain an active proteasome involved in protein processing for antigen presentation via MHC-I molecules
- 2021
-
In: Blood. - : American Society of Hematology. - 1528-0020 .- 0006-4971. ; 138:25, s. 2607-2620

- In addition to their hemostatic role, platelets play a significant role in immunity. Once activated, platelets release extracellular vesicles (EVs) formed by the budding of their cytoplasmic membranes. Because of their heterogeneity, platelet EVs (PEVs) are thought to perform diverse functions. It is unknown, however, whether the proteasome is transferred from platelets to PEVs or whether its function is retained. We hypothesized that functional protein processing and antigen presentation machinery are transferred to PEVs by activated platelets. Using molecular and functional assays, we found that the active 20S proteasome was enriched in PEVs, along with major histocompatibility complex class I (MHC-I) and lymphocyte costimulatory molecules (CD40L and OX40L). Proteasome-containing PEVs were identified in healthy donor blood, but did not increase in platelet concentrates that caused adverse transfusion reactions. They were augmented, however, after immune complex injections in mice. The complete biodistribution of murine PEVs after injection into mice revealed that they principally reached lymphoid organs, such as spleen and lymph nodes, in addition to the bone marrow, and to a lesser extent, liver and lungs. The PEV proteasome processed exogenous ovalbumin (OVA) and loaded its antigenic peptide onto MHC-I molecules, which promoted OVA-specific CD8+ T-lymphocyte proliferation. These results suggest that PEVs contribute to adaptive immunity through cross-presentation of antigens and have privileged access to immune cells through the lymphatic system, a tissue location that is inaccessible to platelets.

- We report the isolation, development and multiplex optimisation of 12 new microsatellite loci for the great scallop, Pecten maximus. Diversity was moderate to high, with number of alleles ranging from 4 to 20 and observed heterozygosity between 0.28 and 0.88. Progeny produced in a commercial hatchery was used to test locus power for parentage assignment. The percentage of offspring that was unambiguously assigned to a unique pair of parents was 97% (software package CERVUS-COLONY). Parentage assignment revealed that 22% of the studied progeny resulted from unplanned crosses. Effective population size of the study progeny was also estimated. Our study illustrates the power of microsatellites for the genetic monitoring of hatchery-produced great scallops.
