Abstract
Per and polyfluoroalkyl substances (PFAS) are persistent compounds that are massively used in industry, consumer goods and fire-fighting foams. Soil contamination by PFAS is a major environmental concern, and there is a lack of knowledge on both their ecotoxicological mechanisms and the concentrations that induce adverse effects especially to non-target organisms, particularly in the case of PFAS mixtures. This study contributes to filling these gaps by assessing and modelling the effects of PFAS (in single and in mixtures for PFOS and PFOA at different environmental doses) on juvenile endogeic earthworms of a common species in European soils (Aporrectodea caliginosa) at different levels of biological organization (sub-individual and individual). The results showed for the first time combined strong ecotoxicological effects of PFAS on earthworm survival, integumental integrity, growth, sexual maturity and on genomic stability notably with the induction of DNA breaks associated with no abnormal oxidative DNA-lesion levels. Our results demonstrated significant effects at 0.3 mg kg-1 and additive effects in case of mixtures.

Abstract
BACKGROUND Nowadays, more than 90% of patients with congenital heart disease (CHD) reach adulthood. However, long-term impact on neurodevelopment and executive functioning in adults with CHD are not completely understood. PURPOSE To investigate the self- and informant-reported executive functioning in adults with CHD operated in childhood. MATERIAL AND METHODS Longitudinal study of a cohort of patients (n = 194, median age: 49.9 [46.1-53.8]) who were operated in childhood (< 15 years old) between 1968 and 1980 (median follow-up time: 45 [40-53] years) for one of the following diagnoses: atrial septal defect (ASD), ventricular septal defect (VSD), pulmonary stenosis (PS), tetralogy of Fallot (ToF) or transposition of the great arteries (TGA). Behavior Rating Inventory of Executive Function-Adult version (BRIEF-A) questionnaire was used to assess self- and informant-reported executive functioning. RESULTS 40-53 years after surgery, the CHD group did show significantly better executive functioning compared to the norm data. No significant difference was found between mild CHD (ASD, VSD and PS) and moderate/severe CHD (ToF and TGA). Higher education, NYHA class 1 and better exercise capacity were associated with better self-reported executive functioning, whereas females or patients taking psychiatric or cardiac medications reported worse executive functioning. CONCLUSIONS Our findings suggest favorable outcomes (comparable to normative data) regarding executive functioning in adults with CHD, both self- and informant-reported. However, further study is warranted to explore more in detail the different cognitive domains of executive functioning in these patients.

Abstract
Background Nowadays, more than 90% of patients with congenital heart disease (CHD) reach adulthood. However, little is known about long-term psychopathological problems in these patients. Purpose To investigate the development of psychological outcomes of adults with CHD operated in their childhood. Material and methods Our unique, single center, longitudinal cohort-study evaluates a series of consecutive patients who underwent cardiac surgery in childhood between 1968 and 1980 every 10 years. Standardized questionnaires were used to measure psychopathology at 4 follow-up time points (1991, 2001, 2011 and 2021) and outcomes were compared with normative data. Results in the current evaluation were corrected for the Covid-19 stringency index. Results At the current (4th) evaluation in 2021, 204 patients (46% female, age: 49.9±5.2) participated. Female patients with CHD reported significantly more internalizing problems than the normative group. More specifically, they reported significantly more somatic complaints. Proxy-reports showed significantly less externalizing problems for males. No significant difference was found between simple and moderate/complex CHD in terms of psychopathology. Correction for Covid-19 pandemic stringency showed no significant effect. Over time, the percentage of patients scoring in the psychopathological range decreased from the first (1991, 25.4%) to the third follow-up (2011, 1.8%). However, the current study showed a significant increase (9.6%) of the psychopathology levels in comparison with 2011. (figure1) Conclusions Compared to normative data, female CHD patients reported significantly more internalizing problems, particularly more somatic complaints. Initially, the level of psychopathology decreased over time. However, in the last decade, there was a significant increase in psychopathology, not explained by the Covid-19 pandemic, warranting continuous attention to the psychological health of adults with CHD.

Abstract
Abstract
Background
For children with congenital heart disease (CHD), subtle neuropsychological deficits have been reported. However, very little is known about executive functioning in their adulthood.
Purpose
To investigate the self- and informant-reported executive functioning in adults with CHD operated in childhood (<15 years old).
Material and methods
A cohort study of 194 patients (age 50 [46–54] years), operated in childhood between 1968 and 1980 for one of the following diagnosis: atrial septal defect (ASD), ventricular septal defect (VSD), pulmonary stenosis (PS), tetralogy of Fallot (ToF) or transposition of the great arteries (TGA), were evaluated 40–53 years after surgery. The “Behavior Rating Inventory of Executive Functions – Adult version” (BRIEF-A) questionnaire was used to assess self- and informant-reported executive functioning and compared to the general population.
Results
The CHD group did not show worse executive functioning compared to normative data. In addition, no significant difference was found between simple CHD (ASD, VSD and PS) and moderate/complex CHD (ToF and TGA).
Higher education and NYHA class 1 were associated with better self-reported executive functioning, while male patients and patients taking psychiatric or cardiac medications reported worse executive functioning.
Conclusions
Overall, our findings suggest reassuring outcomes regarding executive functioning in adults with CHD. However, these findings should be confirmed with neuropsychological assessment studies.

Abstract
Although Glyphosate-based herbicides are often marketed as environmentally friendly and easily biodegradable, its bioavailability and risks to wildlife raise significant concerns. Among non-target organisms, earthworms which live in close contact with the soil can be directly exposed to pesticides and harmed. We investigated soil contamination and the exposure of earthworms to glyphosate, its metabolite AMPA, and glufosinate in an arable landscape in France, both in treated (i.e. temporary grasslands and cereal fields under conventional farming), and nontreated habitats (i.e. hedgerows, permanent grasslands and cereal fields under organic farming) (n = 120 sampling sites in total). Glyphosate, AMPA and glufosinate were detected in 88%, 58% and 35% of the soil samples, and in 74%, 38% and 12% of the earthworm samples, respectively. For both glyphosate and AMPA, concentrations in soils were at least 10 times lower than predicted environmental concentrations. However, the maximum glyphosate soil concentration measured (i.e., 0.598 mg kg-1) was only 2 to 3 times lower than the concentrations revealed to affect earthworms (survival and avoidance) in the literature. These compounds were found both in conventional and organic farming fields, thus supporting a recent study, and for the first time they were detected in hedgerows and grasslands. However, glyphosate and AMPA were more frequently detected in soils from cereal fields and hedgerows than in grasslands, and median concentrations measured in soils from cereal fields were significantly higher than in the two other habitats. Bioaccumulation of glyphosate and AMPA in earthworms was higher than expected according to the properties of the molecules. Our findings raised issues about the high occurrence of glyphosate and AMPA in soils from cropped and more natural areas in arable landscapes. They also highlight the potential for transfer of these molecules in terrestrial food webs as earthworms are prey for numerous animals.

Background
Electromechanical dyssynchrony between right ventricular (RV) free wall and septum contraction in repaired Tetralogy of Fallot (ToF) contributes to inefficient RV mechanics and ultimately reduced systolic function (1). Whilst current assessment of RV synchronicity involves the lateral wall and septum, the use of two-dimensional multi-plane echocardiography (2D-MPE) enables additional RV walls to be evaluated, reflecting global myocardial dynamics (2).
Purpose
The aim of this study is to gain new insights into regional RV wall mechanics using 2D-MPE, determining the potential added value of this imaging model in the assessment of electromechanical synchronicity.
Methods
Twenty ToF patients and fifteen healthy controls underwent detailed RV assessment using 2D-MPE. Furthermore, all ToF patients underwent on the same day cardiac magnetic resonance imaging (cMRI). RV wall longitudinal strain (LS) and synchronicity of contraction were measured using speckle tracking in three different RV walls (lateral, anterior and inferior) and the RV septum. RV synchronicity was assessed by the time to peak (TTP) deformation delay between the basal RV wall and mid septal segment. Additionally, mechanical dispersion was calculated as the standard deviation of average TTP strain values across four (SD-4: basal-mid septal and lateral), six (SD-6: inclusive inferior wall) and eight segments (SD-8: inclusive anterior and inferior walls).
Results
RV wall average LS was significantly lower in ToF patients compared to the control group (-20.8 ± 4.0% vs -28.1 ± 3.6%, p = <0.001). In ToF patients, higher LS values were seen in the lateral (-21.5 ± 4.7%) and inferior (-20.7 ± 3.7%) walls compared to the anterior (-19.0 ± 4.5%) wall. RV wall to septum TTP delay was significantly increased for all segments in ToF patients compared to healthy controls (all p <0.03). In ToF patients, inferior wall-septum TTP delay was 50 [5, 89]ms whilst the lateral (65 [26, 81]ms) and anterior wall (66 [40, 98]ms) delay was longer. In healthy controls meanwhile, peak RV wall and septal deformation occurred almost simultaneously (table 1). SD-4 was significantly greater in ToF patients compared to controls (39 [23, 56]ms vs 14 [0, 21]ms, p = 0.001) however SD-6 and SD-8 were not significantly different (36 [22, 53]ms vs 22 [17, 35], p = 0.09; 31 [17, 51]ms vs 30 [20, 32]ms, p = 0.33). The association between mechanical dispersion measurements and cMRI-derived right ventricular ejection fraction (RVEF) strengthened with the inclusion of additional RV walls (SD-4 R² = -0.18; SD-6 R² = -0.18; SD-8 R² = -0.27).
Conclusion
2D MPE provides new insights into RV regional deformation and evaluates the association between the mechanics of individual RV walls and the septum. Further research is required to expand upon this novel approach for the assessment of regional RV function. Abstract Table 1 Abstract Figure 1

Abstract
BACKGROUND Zellweger syndrome (ZS) is a congenital autosomal recessive disease within the spectrum of peroxisome biogenesis disorders, characterized by the impairment of peroxisome assembly. The presence of peroxisome enzyme deficiencies leads to complex developmental sequelae, progressive disabilities, and multiorgan damage, due to intracellular accumulation of very-long-chain fatty acids (VLCFAs). CASE PRESENTATION We report the case of an infant affected by ZS in which agammaglobulinemia, detected through neonatal screening of congenital immunodeficiencies, appeared as a peculiar trait standing out among all the other classical characteristics of the syndrome. The exome analysis through next-generation sequencing (NGS), which had previously confirmed the diagnostic suspicion of ZS, was repeated, but no mutations causative of inborn error of immunity (humoral defect) were detected. CONCLUSION In this case, no genetic variants accountable for the abovementioned agammaglobulinemia were detected. Given that the scientific literature reports the involvement of peroxisomes in the activation of Nuclear Factor κ-light-chain-enhancer of activated B cells (NF-κB) pathway, which is crucial for B-cell survival, with this work, we hypothesize the existence of a link between ZS and humoral immunodeficiencies. Further studies are required to confirm this hypothesis.

Abstract
Pesticides may harm soil organisms such as earthworms and enchytraeids, but knowledge is lacking on their relative sensitivity to these chemicals and the consequences on soil functions. The aim of this study was to assess the impact of exposure to a commercial fungicide formulation (Swing® Gold, containing dimoxystrobin and epoxiconazole) on the function of earthworms (Aporrectodea caliginosa) and enchytraeids (Enchytraeus buchholzi) in soil organic matter (SOM) mineralization. The soil organisms were incubated alone and together in a 26-day laboratory experiment. At the recommended field rate, the fungicide induced a decrease in the SOM mineralization and a delay in the maximum daily CO2 emissions compared to the control soil without fungicide. Soil fauna also influenced SOM mineralization with a higher cumulated CO2 release after 26 days in the control soil with earthworms (by 21%) than without fauna. When both earthworms and enchytraeids were present, SOM mineralization did not increase, and there was a negative effect on earthworm weight gain. Finally, an alteration of fauna influence with treatment was observed from day 19, meaning that the effect of fauna on SOM mineralization changed with fungicide treatment. Earthworms no longer promoted SOM mineralization when fungicide was present at three-fold the recommended field rate. The effects of enchytraeids on SOM mineralization were similar with and without fungicide exposure. This study underlines the importance of considering the relative sensitivity of soil organisms to environmental factors and interactions between them when assessing soil functioning.

Abstract
The aim of this work is to study the colour and chemical modifications of the surfaces in chestnut wood samples as a consequence of irradiating in a controlled environment. The changes were investigated by a new analytical approach by combining traditional techniques such as reflectance spectrophotometry in the visible range and Fourier transform infrared spectroscopy with new hyperspectral imaging, in order to obtain forecast models to describe the phenomenon. The statistical elaboration of the experimental data allowed to validate the measurements and to obtain models enabling to relate the investigated parameters; the elaboration of the hyperspectral images by chemometric methods allowed for studying the changes in the reflectance spectra. A result of great importance is the possibility to correlate the oxidation of wood chemical components with the colour change in a totally non-invasive modality. This result is particularly relevant in the field of cultural heritage and in general in the control processes of wooden materials.

Abstract
In soil, the determination of total concentration using an exhaustive extraction method has little relevance to evaluate the exposure of an organism to a chemical, because of sorption processes. This study aims to propose a mild extraction method to evaluate the bioavailability of the fungicide epoxiconazole to the earthworm Aporrectodea icterica. Experiments were conducted in soils presenting various textures and organic carbon contents, spiked with formulated epoxiconazole 7 to 56 days prior to their extraction. In parallel, the epoxiconazole concentration was determined in exposed earthworms and the fungicide's effects were evaluated by measuring weight gain, enzymatic activities and total protein contents. Among the various mild chemical solvents tested to evaluate the environmental availability of the fungicide, the 50 mM hydroxypropyl-β-cyclodextrin solution allowed to extract around 30% of epoxiconazole. This percentage corresponded to the ratio determined in exposed A. icterica under similar soil conditions. Furthermore, this mild method was demonstrated to be sensitive to soil sorption capacities and to ageing. The mild extraction method was then applied to explore the relationship between total and (bio)available concentrations in soil and in A. icterica, over 7- or 28-day exposure time. This demonstrated the proportionality between epoxiconazole concentration in earthworm and available in soil (up to 96%, with regression coefficient R(2) = 0.98). Sublethal effects on earthworm remained not significant.

Abstract
Earthworms play a key role in agroecosystem soil processes. This study aims to assess the effects of different doses of a commercial formulation of epoxiconazole (Opus®), a persistent and widely used fungicide, on the earthworm Aporrectodea icterica. A laboratory study was conducted in a natural soil in order to measure effects of Opus® on earthworm mortality, uptake, weight gain, enzymatic activities (catalase and glutathione-S-transferase), and energy resources (lipids and glycogens). The estimated LC50 was 45.5 mg kg(-1), or 268 times the recommended dose. Weight gains were 28, 19, and 13% of the initial weight after 28 days of exposure in the control and D1 and D10 (1 and 10 times the recommended dose) treatments, respectively. No difference was observed for catalase activity between the three treatments, at 7, 14, or 28 days. The glutathion-S-transferase (GST) activity was two times as high in D1 as in D0 at 14 days. At 28 days, glycogen concentration was lower in D10 than in the D1 treatment. This study highlighted moderate sublethal effects of the commercial formulation Opus® for earthworms. Considering that these effects were observed on a species found in cultivated fields, even at recommended rates, much more attention should be paid to this pesticide.

Abstract
Sex hormones play a role in pain perception, a key variable in evaluating the progression and treatment of osteoarthritis. The aim of this study was to determine the relationship between salivary concentrations of four steroid hormones and functional/clinical outcomes after hip and knee arthroplasty. Saliva samples were collected from 24 otherwise healthy patients with osteoarthritis before surgery, on admission to rehabilitation, and at hospital discharge. Salivary concentrations of testosterone, 17β-estradiol, dehydroepiandrosterone (DHEA), and cortisol were immunoassayed. Changes in hormone levels were compared with clinical outcomes, as assessed by functional independence measure (FIM®), Barthel Index (BI), and visual analog scale for pain (VAS) scores. Changes in testosterone levels were significantly inversely correlated with VAS (r= -0.53, p=0.043) and FIM® and BI scores in all patients (r= -0.30, p= 0.043, and r= -0.35, p=0.031, respectively). The testosterone to cortisol ratio was inversely correlated with BI scores in all patients (r= -0.30, p=0.040), and in the men (r= -0.55, p=0.005) and the women (r= -0.28, p=0.042) when analyzed separately. Changes in salivary testosterone concentrations closely correlated with clinical outcome measurements for total hip and knee arthroplasty. Clinical outcome after arthroplasty was generally better among the men.

Abstract
Eosinophils participate in the immune response against Helicobacter pylori, but little is known about their role in the gastritis associated to the infection. We recently demonstrated that the Hp(2-20) peptide derived from H. pylori accelerates wound healing of gastric mucosa by interacting with N-formyl peptide receptors (FPRs) expressed on gastric epithelial cells. The aim of the present study was to investigate whether eosinophils play a role in the repair of gastric mucosa tissue during H. pylori infection. Immuno-histochemistry and transmission electron microscopy were used to detect eosinophils in gastric mucosal biopsies. Eosinophil re-distribution occurred in the gastric mucosa of H. pylori-infected patients: their density did not change in the deep mucosal layer, whereas it increased in the superficial lamina propria just below the foveolar epithelium; eosinophils entered the epithelium itself as well as the lumen of foveolae located close to the area harboring bacteria, which in turn were also engulfed by eosinophils. The H. pylori-derived peptide Hp(2-20) stimulated eosinophil migration through the engagement of FPR2 and FPR3, and also induced production of VEGF-A and TGF-beta, two key mediators of tissue remodelling. We also demonstrate that Hp(2-20) in vivo induced eosinophil infiltration in rat gastric mucosa after injury brought about by indomethacin. This study suggests that eosinophil infiltrate could modulate the capacity of gastric mucosa to maintain or recover its integrity thereby shedding light on the role of eosinophils in H. pylori infection.

Abstract
Pesticide risk assessments include experiments designed to measure the effect of pesticides on earthworms using the Eisenia fetida fetida or Eisenia fetida andrei species. There is no clear consensus in the literature on the sensitivity of different earthworm species to pesticides. We performed a meta-analysis on the sensitivity of several earthworm species to pesticides to determine the most sensitive species, and to discuss their suitability for European homologation tests. A dataset including median lethal dose (LC50) values reported in 44 experimental treatments was constructed and then analyzed in order to compare the sensitivity levels of E. fetida with that of other earthworm species. Results showed that LC50 values reported for Lumbricus terrestris and Aporrectodea caliginosa were on average significantly lower than for E. fetida. Considering the relatively high LC50 values reported for E. fetida and the absence of this species from zones where pesticides are usually applied, the relevance of using E. fetida for pesticide homologation tests is questionable and we advise risk assessors to use A. caliginosa as model species. A new protocol based on this species could be proposed for European homologation tests but its implementation will require the definition of a new standard and take time. In the meantime, the results obtained with E. fetida should be interpreted with caution taking into account the low sensitivity of this species. Our study illustrates the value of the meta-analysis approach for comparing the sensitivity of different earthworm species to pesticides. It would be useful to extend the dataset presented in this paper in order to analyze the sensitivity of other aquatic or terrestrial organism groups used for pesticide homologation or ecotoxicology tests.
