Sustainability limits needed for CO2 removal.

The true climate mitigation challenge is revealed by considering sustainability impacts.

Cordylobia anthropophaga Myiasis Mimicking Hyperproliferative Skin Disorder in Traveler Returning from Sub-Saharan Africa.

Myiasis is one of the most common skin diseases found in travelers returning from tropical and subtropical regions, where humans living in or visiting the African continent are most commonly infested by C. anthropophaga during the rainy season in regions with a warm climate. Here, we present a case of furuncular myiasis caused by C. anthropophaga in a Serbian patient returning from temporary work in Kenya, where the initial histology of skin lesion mimicked hyperproliferative skin disorder.

A metric for spatially explicit contributions to science-based species targets.

The Convention on Biological Diversity's post-2020 Global Biodiversity Framework will probably include a goal to stabilize and restore the status of species. Its delivery would be facilitated by making the actions required to halt and reverse species loss spatially explicit. Here, we develop a species threat abatement and restoration (STAR) metric that is scalable across species, threats and geographies. STAR quantifies the contributions that abating threats and restoring habitats in specific places offer towards reducing extinction risk. While every nation can contribute towards halting biodiversity loss, Indonesia, Colombia, Mexico, Madagascar and Brazil combined have stewardship over 31% of total STAR values for terrestrial amphibians, birds and mammals. Among actions, sustainable crop production and forestry dominate, contributing 41% of total STAR values for these taxonomic groups. Key Biodiversity Areas cover 9% of the terrestrial surface but capture 47% of STAR values. STAR could support governmental and non-state actors in quantifying their contributions to meeting science-based species targets within the framework.

Influence of the residence time of street trees and their soils on trace element contamination in Paris (France).

With the actual increasing interest for urban soils, the evaluation of soil contamination by trace elements and the dynamics of this contamination appear mandatory to preserve plant and thereby human health. Street trees and the associated soil placed in pits located nearby roads could represent convenient indicators of urban and vehicle traffic influences on soils and plants. However, data on these soils remain scarce, many studies investigating park soils rather than street tree soils. Furthermore, trace elements could be one of the main factors causing the observed urban tree decline, while practitioners more and more question the possible reuse of these soils after the death of trees as well as tree litter collected in the streets. We evaluated the contamination in anthropogenic trace elements (TE), namely Zn, Pb, and Cd, of street trees (Tilia tomentosa) and their soils distributed all over Paris (France). Street tree soils are imported from rural areas at the plantation of each new tree so that tree age corresponds to the time of residence of the soil within an urban environment allowing the evaluation of temporal trends on TE concentration in soils and trees. The TE concentration revealed an important soil pollution, especially for the older soils (mean age of 80 years old). The consideration of the residence time of trees and soils in an urban environment evidenced an accumulation of Zn and Pb (ca. 4.5 mg kg-1 year-1 and 4 mg kg-1 year-1 for Zn and Pb, respectively). However, leaf concentrations in TE were low and indicate that soil-root transfer was not significant compared to the contamination by atmospheric deposition. These results underlined the necessity to deepen the evaluation of the recycling of urban soils or plants submitted to urban contamination.

Why are social sciences and humanities needed in the works of IPBES? A systematic review of the literature.

Despite the increased attention, which has been given to the issue of involving knowledge and experts from the social sciences and humanities (SSH) into the products and works of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), little is known on what the expectations towards the involvement of SSH in IPBES actually are. The aim of this paper is to close this gap by identifying the range of possible SSH contributions to IPBES that are expected in the literature, and discuss the inherent challenges of and concrete ways to realize these contributions in the particular institutional setting of IPBES. We address these two points by: firstly, assessing the literature dealing with IPBES and building a typology describing the main ways in which contributions from SSH to IPBES have been conceived between 2006 and 2017. We discuss these expected contributions in light of broader debates on the role of SSH in nature conservation and analyse some of the blind spots and selectivities in the perception of how SSH could substantially contribute to the works of IPBES. Then, secondly, by looking at one particular example, economics and its use in the first thematic assessment on pollinators, pollination and food production, we will concretely illustrate how works in a given discipline could contribute in many different and unprecedented ways to the works of IPBES and help identify paths for enhancing the conservation of biodiversity. Finally, we propose a range of practical recommendations as to how to increase the contribution of SSH in the works of IPBES.

Two-Year Complete Remission of Diffuse Large B-Cell Lymphoma in an Immunological Nonresponder HIV-Infected Patient: Case Report.

INTRODUCTION: HIV-infected patients are affected significantly more frequently by all types of lymphoma, with diffuse large B-cell lymphoma (DLBCL) as the most prevalent histological type. Since the introduction of combination antiretroviral therapy (cART) morbidity and mortality of DLBCL has been markedly reduced, which is primarily interpreted as a result of the drug-mediated immune reconstitution. CASE REPORT: We present a previously healthy, 44-year-old HIV-infected man with DLBCL of the oral cavity, treated with immunochemotherapy and cART. During HIV-directed treatment, despite the successful virologic response, a satisfactory immunological response was not achieved. However, the patient had a 2-year complete remission after first-line treatment of DLBCL. CONCLUSION: Response to cART strongly predicts outcome in patients with DLBCL. Close monitoring of HIV-directed therapy efficacy, especially as to achievement of successful virologic response, independently associated with prolonged survival, is essential for estimating future DLBCL treatment strategies.

Assessment of trace metal air pollution in Paris using slurry-TXRF analysis on cemetery mosses.

Mosses are useful, ubiquitous accumulation biomonitors and as such can be used for biomonitoring surveys. However, the biomonitoring of atmospheric pollution can be compromised in urban contexts if the targeted biomonitors are regularly disturbed, irregularly distributed, or are difficult to access. Here, we test the hypothesis that cemeteries are appropriate moss sampling sites for the evaluation of air pollution in urban areas. We sampled mosses growing on gravestones in 21 urban and peri-urban cemeteries in the Paris metropolitan area. We focused on Grimmia pulvinata (Hedwig) Smith, a species abundantly found in all studied cemeteries and very common in Europe. The concentration of Al, As, Br, Ca, Ce, Cl, Cr, Cu, Fe, K, Mn, Ni, V, P, Pb, Rb, S, Sr, Ti, and Zn was determined by a total reflection X-ray fluorescence technique coupled with a slurry sampling method (slurry-TXRF). This method avoids a digestion step, reduces the risk of sample contamination, and works even at low sample quantities. Elemental markers of road traffic indicated that the highest polluted cemeteries were located near the highly frequented Parisian ring road and under the influence of prevailing winds. The sites with the lowest pollution were found not only in the peri-urban cemeteries, adjoining forest or farming landscapes, but also in the large and relatively wooded cemeteries located in the center of Paris. Our results suggest that (1) slurry-TXRF might be successfully used with moss material, (2) G. pulvinata might be a good biomonitor of trace metals air pollution in urban context, and (3) cemetery moss sampling could be a useful complement for monitoring urban areas. Graphical abstract We tested the hypothesis that cemeteries are appropriate moss sampling sites for the evaluation of air pollution in urban areas. We sampled 110 moss cushions (Grimmia pulvinata) growing on gravestones in 21 urban and peri-urban cemeteries in the Paris metropolitan area. The concentration of 20 elements in mosses was determined by a total reflection X-ray fluorescence technique coupled with a slurry sampling method. Statistical analysis revealed that: - Urbanized Parisian areas crossed by traffic roads have the highest polluted cemeteries with a strong influence of main wind direction on the distribution of air pollutants - As expected, small cemeteries with low tree density were heavily polluted - Less obvious, large green spaces such as large cemeteries (Père Lachaise, Montmartre, Montparnasse) in the center of a dense metropolis like Paris present the same level of atmospheric trace metal pollution as cemeteries in less urbanized areas or nearing a very large forest. This suggests that even in densely urbanized areas, there is more spatial variability in pollution distribution than usually assumed and that large urban areas with low traffic and green filters such as trees are likely to intercept air pollutants.

Anaphylactic shock due to unruptured hepatic hydatid cyst complicated by multiple intrahospital infections.

Anaphylactic shock due to unruptured hydatid cyst is a rare complication of hepatic echinococcosis. Here, we present an unusual case of unruptured hydatid cyst causing anaphylactic shock followed by appendicitis, ileus, and complicated by septic condition due to multiple intrahospital infections. Decision of the surgical cyst removal at the right moment and appropriate antimicrobial treatment are key factors for a positive outcome.

Listeria monocytogenes meningitis in an immunocompetent 18-year-old patient as a possible diagnostic and therapeutical problem.

INTRODUCTION: Listeria monoytogenes is the third most frequent cause of bacterial meningitis in adults. It commonly affects persons with defective cell-mediated immunity or advanced age, and only a few patiens with no underlying predisposition have been reported. CASE REPORT: We presented an previously healthy, 18-year-old man with typical clinical features of meningitis. On the account of earlier treatment with ceftriaxone and cerebrospinal fluid finding, an assumption of partially treated bacterial meningitis was made. The initial treatment with vancomycin and ceftriaxone, substituted on day 4 with meropenem, did not produce any clinical effect. On day 6 Listeria monocytogenes was isolated and, even as late as that, the administration of ampicillin was followed by complete recovery of the patient. CONCLUSION: In younger, immunocompetent individuals, in spite of the existent diagnostic and therapeutic problems, the subacute course of Listeria monocytogenes meningitis provides enough time for appropriate treatment and favorable disease outcome.

Use of ecosystem services economic valuation for decision making: questioning a literature blindspot.

Ecosystem Services economic Valuation (ESV) is often seen as a tool that can potentially enhance our collective choices regarding ecosystem services as it factors in the costs and benefits of their degradation. Yet, to achieve this, the social processes leading to decisions need to use ESV effectively. This makes it necessary to understand if and how ESV is or is not used by decision-makers. However, there appears to be a literature blindspot as to the issue of the Use of Ecosystem Services economic Valuation (UESV). This paper proposes a systematic review on UESV in peer-reviewed scientific literature. It shows that this literature gives little attention to this issue and rarely reports cases where ESV has been put to actual use, even though such use is frequently referred to as founding the goal and justification of ESV. The review identifies three categories of potential UESV: decisive, technical and informative, which are usually mentioned as prospects for the valuations published. Two sets of hypotheses are examined to explain this result: either the use of ESV is a common practice, but is absent from the literature reviewed here; or the use of ESV is effectively rare. These hypotheses are discussed and open up further avenues of research which should make the actual use of ESV their core concern.
