Nouveaux Orthoptères (Ensifera, Insecta) du Trias des Vosges (France)
Trois nouveaux Orthoptera, Ensifera (Hagloidea et Gryllavoidea) du Grès à Voltzia (Buntsandstein supérieur, Trias inférieur/moyen) des Vosges (France) représentés par des ailes antérieures, sont décrits. Galliagryllavus vogesiacus n. gen., n.sp. (Gryllavidae) montre des affinités avec Gryllavus madyge nicus SHAROV 1968 du Trias de Madygen (Kirghizistan). Triassoparacyrtophyllites bifurcatus n. gen., n.sp. (Tuphellidae) présente des analogies avec Pa racyrtophillites undulatus SHAROV 1968 du Jurassique supérieur de Karatau (Kazakhstan). Voltziahagla pseudoveinosa n. gen., n.sp. (Haglidae) semble proche du genre Archaboilus MARTYNOV 1937 du Jurassique inférieur de Shurab (Tadjikistan).

Co-benefits from sustainable dietary shifts for population and environmental health: an assessment from a large European cohort study
Funding European Commission (DG-SANCO) , the International Agency for Research on Cancer (IARC) , MRC Early Career Fellowship (MR/M501669/1) .Background Unhealthy diets, the rise of non-communicable diseases, and the declining health of the planet are highly
intertwined, where food production and consumption are major drivers of increases in greenhouse gas emissions,
substantial land use, and adverse health such as cancer and mortality. To assess the potential co-benefits from shifting
to more sustainable diets, we aimed to investigate the associations of dietary greenhouse gas emissions and land use
with all-cause and cause-specific mortality and cancer incidence rates.
Methods Using data from 443 991 participants in the European Prospective Investigation into Cancer and Nutrition
(EPIC) study, a multicentre prospective cohort, we estimated associations between dietary contributions to greenhouse
gas emissions and land use and all-cause and cause-specific mortality and incident cancers using Cox proportional
hazards regression models. The main exposures were modelled as quartiles. Co-benefits, encompassing the potential
effects of alternative diets on all-cause mortality and cancer and potential reductions in greenhouse gas emissions and
land use, were estimated with counterfactual attributable fraction intervention models, simulating potential effects of
dietary shifts based on the EAT–Lancet reference diet.
Findings In the pooled analysis, there was an association between levels of dietary greenhouse gas emissions and allcause
mortality (adjusted hazard ratio [HR] 1·13 [95% CI 1·10–1·16]) and between land use and all-cause mortality
(1·18 [1·15–1·21]) when comparing the fourth quartile to the first quartile. Similar associations were observed for
cause-specific mortality. Associations were also observed between all-cause cancer incidence rates and greenhouse
gas emissions, when comparing the fourth quartile to the first quartile (adjusted HR 1·11 [95% CI 1·09–1·14]) and
between all-cause cancer incidence rates and land use (1·13 [1·10–1·15]); however, estimates differed by cancer type.
Through counterfactual attributable fraction modelling of shifts in levels of adherence to the EAT–Lancet diet, we
estimated that up to 19–63% of deaths and up to 10–39% of cancers could be prevented, in a 20-year risk period, by
different levels of adherence to the EAT–Lancet reference diet. Additionally, switching from lower adherence to the
EAT–Lancet reference diet to higher adherence could potentially reduce food-associated greenhouse gas emissions
up to 50% and land use up to 62%.
Interpretation Our results indicate that shifts towards universally sustainable diets could lead to co-benefits, such as
minimising diet-related greenhouse gas emissions and land use, reducing the environmental footprint, aiding in
climate change mitigation, and improving population health.European Commission

Characterization of the degree of food processing in the European Prospective Investigation into Cancer and Nutrition: Application of the Nova classification and validation using selected biomarkers of food processing
Background: Epidemiological studies have demonstrated an association between the degree of food processing in our diet and the risk of various chronic diseases. Much of this evidence is based on the international Nova classification system, which classifies food into four groups based on the type of processing: (1) Unprocessed and minimally processed foods, (2) Processed culinary ingredients, (3) Processed foods, and (4) “Ultra-processed” foods (UPF). The ability of the Nova classification to accurately characterise the degree of food processing across consumption patterns in various European populations has not been investigated so far. Therefore, we applied the Nova coding to data from the European Prospective Investigation into Cancer and Nutrition (EPIC) in order to characterize the degree of food processing in our diet across European populations with diverse cultural and socio-economic backgrounds and to validate this Nova classification through comparison with objective biomarker measurements. Methods: After grouping foods in the EPIC dataset according to the Nova classification, a total of 476,768 participants in the EPIC cohort (71.5% women; mean age 51 [standard deviation (SD) 9.93]; median age 52 [percentile (p)25–p75: 58–66] years) were included in the cross-sectional analysis that characterised consumption patterns based on the Nova classification. The consumption of food products classified as different Nova categories were compared to relevant circulating biomarkers denoting food processing, measured in various subsamples (N between 417 and 9,460) within the EPIC cohort via (partial) correlation analyses (unadjusted and adjusted by sex, age, BMI and country). These biomarkers included an industrial transfatty acid (ITFA) isomer (elaidic acid; exogenous fatty acid generated during oil hydrogenation and heating) and urinary 4-methyl syringol sulfate (an indicator for the consumption of smoked food and a component of liquid smoke used in UPF). Results: Contributions of UPF intake to the overall diet in % grams/day varied across countries from 7% (France) to 23% (Norway) and their contributions to overall % energy intake from 16% (Spain and Italy) to >45% (in the UK and Norway). Differences were also found between sociodemographic groups; participants in the highest fourth of UPF consumption tended to be younger, taller, less educated, current smokers, more physically active, have a higher reported intake of energy and lower reported intake of alcohol. The UPF pattern as defined based on the Nova classification (group 4;% kcal/day) was positively associated with blood levels of industrial elaidic acid (r = 0.54) and 4-methyl syringol sulfate (r = 0.43). Associations for the other 3 Nova groups with these food processing biomarkers were either inverse or non-significant (e.g., for unprocessed and minimally processed foods these correlations were –0.07 and –0.37 for elaidic acid and 4-methyl syringol sulfate, respectively). Conclusion: These results, based on a large pan-European cohort, demonstrate sociodemographic and geographical differences in the consumption of UPF. Furthermore, these results suggest that the Nova classification can accurately capture consumption of UPF, reflected by stronger correlations with circulating levels of industrial elaidic acid and a syringol metabolite compared to diets high in minimally processed foods

Clinical, Epidemiologic, Histopathologic and Molecular Features of an Unexplained Dermopathy
BACKGROUND: Morgellons is a poorly characterized constellation of symptoms, with the primary manifestations involving the skin. We conducted an investigation of this unexplained dermopathy to characterize the clinical and epidemiologic features and explore potential etiologies. METHODS: A descriptive study was conducted among persons at least 13 years of age and enrolled in Kaiser Permanente Northern California (KPNC) during 2006-2008. A case was defined as the self-reported emergence of fibers or materials from the skin accompanied by skin lesions and/or disturbing skin sensations. We collected detailed epidemiologic data, performed clinical evaluations and geospatial analyses and analyzed materials collected from participants' skin. RESULTS: We identified 115 case-patients. The prevalence was 3.65 (95% CI = 2.98, 4.40) cases per 100,000 enrollees. There was no clustering of cases within the 13-county KPNC catchment area (p = .113). Case-patients had a median age of 52 years (range: 17-93) and were primarily female (77%) and Caucasian (77%). Multi-system complaints were common; 70% reported chronic fatigue and 54% rated their overall health as fair or poor with mean Physical Component Scores and Mental Component Scores of 36.63 (SD = 12.9) and 35.45 (SD = 12.89), respectively. Cognitive deficits were detected in 59% of case-patients and 63% had evidence of clinically significant somatic complaints; 50% had drugs detected in hair samples and 78% reported exposure to solvents. Solar elastosis was the most common histopathologic abnormality (51% of biopsies); skin lesions were most consistent with arthropod bites or chronic excoriations. No parasites or mycobacteria were detected. Most materials collected from participants' skin were composed of cellulose, likely of cotton origin. CONCLUSIONS: This unexplained dermopathy was rare among this population of Northern California residents, but associated with significantly reduced health-related quality of life. No common underlying medical condition or infectious source was identified, similar to more commonly recognized conditions such as delusional infestation

Changes to the Fossil Record of Insects through Fifteen Years of Discovery
The first and last occurrences of hexapod families in the fossil record are compiled from publications up to end-2009. The major features of these data are compared with those of previous datasets (1993 and 1994). About a third of families (>400) are new to the fossil record since 1994, over half of the earlier, existing families have experienced changes in their known stratigraphic range and only about ten percent have unchanged ranges. Despite these significant additions to knowledge, the broad pattern of described richness through time remains similar, with described richness increasing steadily through geological history and a shift in dominant taxa, from Palaeoptera and Polyneoptera to Paraneoptera and Holometabola, after the Palaeozoic. However, after detrending, described richness is not well correlated with the earlier datasets, indicating significant changes in shorter-term patterns. There is reduced Palaeozoic richness, peaking at a different time, and a less pronounced Permian decline. A pronounced Triassic peak and decline is shown, and the plateau from the mid Early Cretaceous to the end of the period remains, albeit at substantially higher richness compared to earlier datasets. Origination and extinction rates are broadly similar to before, with a broad decline in both through time but episodic peaks, including end-Permian turnover. Origination more consistently exceeds extinction compared to previous datasets and exceptions are mainly in the Palaeozoic. These changes suggest that some inferences about causal mechanisms in insect macroevolution are likely to differ as well
