Abstract
Cognitive enrichment is a promising but understudied type of environmental enrichment that aims to stimulate the cognitive abilities of animals by providing them with more opportunities to interact with (namely, to predict events than can occur) and to control their environment. In a previous study, we highlighted that farmed rainbow trout can predict daily feedings after two weeks of conditioning, the highest conditioned response being elicited by the combination of both temporal and signalled predictability. In the present study, we tested the feeding predictability that elicited the highest conditioned response in rainbow trout (both temporal and signalled by bubbles, BUBBLE + TIME treatment) as a cognitive enrichment strategy to improve their welfare. We thus analysed the long-term effects of this feeding predictability condition as compared with an unpredictable feeding condition (RANDOM treatment) on the welfare of rainbow trout, including the markers in the modulation of brain function, through a multidisciplinary approach. To reveal the brain regulatory pathways and networks involved in the long-term effects of feeding predictability, we measured gene markers of cerebral activity and plasticity, neurotransmitter pathways and physiological status of fish (oxidative stress, inflammatory status, cell type and stress status). After almost three months under these predictability conditions of feeding, we found clear evidence of improved welfare in fish from BUBBLE + TIME treatment. Feeding predictability allowed for a food anticipatory activity and resulted in fewer aggressive behaviours, burst of accelerations, and jumps before mealtime. BUBBLE + TIME fish were also less active between meals, which is in line with the observed decreased expression of transcripts related to the dopaminergic system. BUBBLE + TIME fish tented to present fewer eroded dorsal fin and infections to the pathogen Flavobacterium psychrophilum. Decreased expression of most of the studied mRNA involved in oxidative stress and immune responses confirm these tendencies else suggesting a strong role of feeding predictability on fish health status and that RANDOM fish may have undergone chronic stress. Fish emotional reactivity while isolated in a novel-tank as measured by fear behaviour and plasma cortisol levels were similar between the two treatments, as well as fish weight and size. To conclude, signalled combined with temporal predictability of feeding appears to be a promising approach of cognitive enrichment to protect brain function via the physiological status of farmed rainbow trout in the long term.

Abstract
BACKGROUND High dietary carbohydrates can spare protein in rainbow trout (Oncorhynchus mykiss) but may affect growth and health. Inulin, a prebiotic, could have nutritional and metabolic effects, along with anti-inflammatory properties in teleosts, improving growth and welfare. We tested this hypothesis in rainbow trout by feeding them a 100% plant-based diet, which is a viable alternative to fishmeal and fish oil in aquaculture feeds. In a two-factor design, we examined the impact of inulin (2%) as well as the variation in the carbohydrates (CHO)/plant protein ratio on rainbow trout. We assessed the influence of these factors on zootechnical parameters, plasma metabolites, gut microbiota, production of short-chain fatty acids and lactic acid, as well as the expression of free-fatty acid receptor genes in the mid-intestine, intermediary liver metabolism, and immune markers in a 12-week feeding trial. RESULTS The use of 2% inulin did not significantly change the fish intestinal microbiota, but interestingly, the high CHO/protein ratio group showed a change in intestinal microbiota and in particular the beta diversity, with 21 bacterial genera affected, including Ralstonia, Bacillus, and 11 lactic-acid producing bacteria. There were higher levels of butyric, and valeric acid in groups fed with high CHO/protein diet but not with inulin. The high CHO/protein group showed a decrease in the expression of pro-inflammatory cytokines (il1b, il8, and tnfa) in liver and a lower expression of the genes coding for tight-junction proteins in mid-intestine (tjp1a and tjp3). However, the 2% inulin did not modify the expression of plasma immune markers. Finally, inulin induced a negative effect on rainbow trout growth performance irrespective of the dietary carbohydrates. CONCLUSIONS With a 100% plant-based diet, inclusion of high levels of carbohydrates could be a promising way for fish nutrition in aquaculture through a protein sparing effect whereas the supplementation of 2% inulin does not appear to improve the use of CHO when combined with a 100% plant-based diet.

Abstract
Very-long chain acyl-CoA dehydrogenase (VLCAD) catalyzes the initial step of mitochondrial long chain (LC) fatty acid β-oxidation (FAO). Inherited VLCAD deficiency (VLCADD) predisposes to neonatal arrhythmias whose pathophysiology is still not understood. We hypothesized that VLCADD results in global disruption of cardiac complex lipid homeostasis, which may set conditions predisposing to arrhythmia. To test this, we assessed the cardiac lipidome and related molecular markers in seven-month-old VLCAD-/- mice, which mimic to some extent the human cardiac phenotype. Mice were sacrificed in the fed or fasted state after receiving for two weeks a chow or a high-fat diet (HFD), the latter condition being known to worsen symptoms in human VLCADD. Compared to their littermate counterparts, HFD/fasted VLCAD-/- mouse hearts displayed the following lipid alterations: (1) Lower LC, but higher VLC-acylcarnitines accumulation, (2) higher levels of arachidonic acid (AA) and lower docosahexaenoic acid (DHA) contents in glycerophospholipids (GPLs), as well as (3) corresponding changes in pro-arrhythmogenic AA-derived isoprostanes and thromboxane B2 (higher), and anti-arrythmogenic DHA-derived neuroprostanes (lower). These changes were associated with remodeling in the expression of gene or protein markers of (1) GPLs remodeling: higher calcium-dependent phospholipase A2 and lysophosphatidylcholine-acyltransferase 2, (2) calcium handling perturbations, and (3) endoplasmic reticulum stress. Altogether, these results highlight global lipid dyshomeostasis beyond FAO in VLCAD-/- mouse hearts, which may set conditions predisposing the hearts to calcium mishandling and endoplasmic reticulum stress and thereby may contribute to the pathogenesis of arrhythmias in VLCADD in mice as well as in humans.

Abstract
Metal oxide nanoparticles (MeOxNPs) can be made safer by understanding the interaction between the immune system and nanoparticles. A nano-quantitative structure-activity relationship (nano-QSAR) model can be used to evaluate nanoparticle risk quickly and conveniently. The present work attempts to develop nano-QSAR models to determine the inflammatory potential of MeOxNPs based on the THP-1 cell line. A comprehensive dataset comprising 32 MeOxNPs was used to develop a regression model with fold change (FC) of pro-inflammatory cytokine interleukin (IL)-1beta (IL-1b) release in the THP-1 cell line as the endpoint. Further, the same number of MeOx NPs with varying doses was modelled for the cell viability [-ln(p/(1-p))] endpoint. The results obtained from regression models were statistically significant. The descriptors obtained from the developed predictive models inferred that dose, electronegativity and the presence of metal ions and oxygen can be responsible for IL-1β leakage from the THP-1 cell line. Based on our results, we can conclude that periodic table-based descriptors, incorporated into the QSAR models, are reliable for modelling pro-inflammatory potential. Researchers can use these comprehensive results to design metal oxide nanoparticles with lower toxicity and determine the cause of pro-inflammatory conditions induced by MeOxNPs.

Abstract
Rainbow trout (Oncorhynchus mykiss) is traditionally considered as a poor user of digestible carbohydrates harbouring persistent postprandial hyperglycaemia and decreased growth performances when fed a diet containing more than 20% of digestible carbohydrates. While this glucose-intolerant phenotype is well-described in juveniles, evidence points to a particular regulation of glucose metabolism in rainbow trout broodstrocks. By detecting changes in glucose levels and triggering a specific metabolic response, the hypothalamus plays a key role in the regulation of peripheral glucose metabolism. Therefore, our objective was to assess, for the first time in fish, the short-term consequences in hypothalamus, the glucose sensing and feed intake regulation of feeding mature female and male, and neomale rainbow trout with a diet containing either no or a 33% carbohydrate. The hypothalamic glucosensing capacity was assessed through mRNA levels of glucosensing related-genes and feed intake regulation through appetite-regulating peptides. Our data indicate that a brief period of carbohydrate intake (5 meals at 8 °C) did not induce specific changes in glucosensing capacity and appetite-regulating peptides in the hypothalamus of rainbow trout broodstock. Our results did however demonstrate, for the first time in fish, the existence of sex dimorphism of glucosensing-related genes and appetite-regulating peptides.

Abstract
Soil invertebrates serve as great biological indicators of soil quality. However, there are very few in silico models developed so far on the soil toxicity of chemicals against soil invertebrates due to paucity of data. In this study, three available soil ecotoxicity data (pLC50, pLOEL and pNOEL) against the soil invertebrate Folsomia candida were collected from the ECOTOX database (cfpub.epa.gov/ecotox) and subjected to quantitative structure-activity relationship (QSAR) analysis using 2D descriptors. The collected data for each endpoint were initially curated and used to develop a partial least squares (PLS) regression model based on the features selected through a genetic algorithm followed by the best subset selection. Both internal and external validation metrics of the models' predictions are well-balanced and within the acceptable range as per the Organization for the Economic Cooperation and Development (OECD) criteria. From the developed models, it has been found that molecular weight and presence of phosphate group, electron donor groups, and polyhalogen substitution have a significant impact on the soil ecotoxicity. The soil ecotoxicological risk assessment of organic chemicals can therefore be prioritized by these features. With the availability of additional data in the future, the models may be further refined for more precise predictions.

Abstract
Since 20 years of research, free fatty acids receptors (FFARs) have received considerable attention in mammals. To date, four FFARs (FFAR1, FFAR2, FFAR3 and FFAR4) are especially studied owing to their physiological importance in various biological processes. This ubiquitist group of G protein-coupled receptors (GPCRs) are majors reports in the key physiological functions such as the regulation of energy balance, metabolism or fatty acid sensing. However, up till date, even some studies were interested in their potential involvement in fatty acid metabolism, no genome investigation of these FFARs have been carried out in teleost fish. Through genome mining and phylogenetic analysis, we identified and characterised 7 coding sequences for ffar2 in rainbow trout whereas no ffar3 nor ffar4 gene have been found. This larger repertoire of ffar2 genes in rainbow trout results from successive additional whole-genome duplications which occurred in early teleosts and salmonids, respectively. A syntenic analysis was used to assign a new nomenclature to the salmonid ffar2 and showed a clear conservation of genomic organisation, further supporting the identity of these genes as ffar2. RT-qPCR was then used to examine, firstly during ontogenesis and secondly on feeding response the expression pattern of ffar1 and ffar2 genes in proximal gut and brain of all trout ffar genes. Overall, this study presents a comprehensive overview of the ffar family in rainbow trout.

Abstract
Reliable neutron star mass measurements are key to determining the equation of state of cold nuclear matter, but such measurements are rare. Black widows and redbacks are compact binaries consisting of millisecond pulsars and semi-degenerate companion stars. Spectroscopy of the optically bright companions can determine their radial velocities, providing inclination-dependent pulsar mass estimates. Although inclinations can be inferred from subtle features in optical light curves, such estimates may be systematically biased due to incomplete heating models and poorly understood variability. Using data from the Fermi Large Area Telescope, we have searched for gamma-ray eclipses from 49 spider systems, discovering significant eclipses in 7 systems, including the prototypical black widow PSR B1957+20. Gamma-ray eclipses require direct occultation of the pulsar by the companion, and so the detection, or significant exclusion, of a gamma-ray eclipse strictly limits the binary inclination angle, providing new robust, model-independent pulsar mass constraints. For PSR B1957+20, the eclipse implies a much lighter pulsar (1.81 ± 0.07 solar masses) than inferred from optical light curve modelling.

Abstract
Stresses associated with changes in diet or environmental disturbances are common situations that fish encounter during their lifetime. The stability and ease of measuring microRNAs (miRNAs) present in biological fluids make these molecules particularly interesting biomarkers for non-lethal assessment of stress in animals. Rainbow trout were exposed for four weeks to abiotic stress (moderate hypoxia) and/or nutritional stress (a high-carbohydrate/low-protein diet). Blood plasma and epidermal mucus were sampled at the end of the experiment, and miRNAs were assessed using small RNA sequencing. We identified four miRNAs (miR-122-5p, miR-184-3p, miR-192-5p and miR-194a-5p) and three miRNAs (miR-210-3p, miR-153a-3p and miR-218c-5p) that accumulated in response to stress in blood plasma and epidermal mucus, respectively. In particular, the abundance of miR-210-3p, a hypoxamiR in mammals, increased strongly in the epidermal mucus of rainbow trout subjected to moderate hypoxia, and can thus be considered a relevant biomarker of hypoxic stress in trout. We explored the contribution of 22 tissues/organs to the abundance of circulating miRNAs (c-miRNAs) in blood plasma and epidermal mucus influenced by the treatments. Some miRNAs were tissue-specific, while others were distributed among several tissues. Some c-miRNAs (e.g., miR-210-3p, miR184-3p) showed similar variations in both tissues and fluids, while others showed an inverse trend (e.g., miR-122-5p) or no apparent relationship (e.g. miR-192-5p, miR-194a-5p. Overall, these results demonstrate that c-miRNAs can be used as non-lethal biomarkers to study stress in fish. In particular, the upregulation of miR-210-3p in epidermal mucus induced by hypoxia demonstrates the potential of using epidermal mucus as a matrix for identifying non-invasive biomarkers of stress. This study provides information about the tissue sources of c-miRNAs and highlights the potential difficulty in relating variations in miRNA abundance in biological fluids to that in tissues.

Abstract
Abstract
Aim
The purpose of this study was to investigate the learning curve of open anterior mesh repair for groin hernia by assessing hernia recurrence rates, surgical complications, and operative times in relation to the number of procedures performed by surgical trainees.
Materials & Methods
Nationwide data on open anterior mesh repair for groin hernia performed by surgical residents were collected from the Swedish Hernia Register between 2005 and 2020. Data were analyzed in a cohort of procedures carried out by surgeons performing their first registered repair as resident. Repairs performed by surgeons who had carried out less than 30 repairs or any repair 1992–2005 were excluded.
Results
The study group consisted of 38 854 repairs carried out by 663 surgeons. The complication rate increased from 298/9884 (3.0%) the first 15 repairs performed to 396/10978 (3.6%) repairs 31–60 and then decreased to 4/945 (0.4%) for repairs performed after the first 240 ones. Mean operation time decreased from 79 minutes (standard deciation [SD] 26 minutes) the first 15 repairs to 60 minutes (SD 23 minutes) for repairs performed after the first 240 ones. Recurrence rates remained unchanged during the learning curve.
Conclusions
It is safe for resident surgeons to perform uncomplicated, elective, anterior groin hernia mesh repair after having completed of at least 60 procedures.

Abstract
Simple Summary Overall, this study has reported that environmental enrichment significantly displayed a series of differentially expressed genes and pathways related to cerebral activity, neural plasticity (neurotrophic markers), neurogenesis, and synaptogenesis, essentially in telencephalon, which may underpin the beneficial effects of a complex environment on rainbow trout’s adaptive behaviors. In addition, environmental enrichment significantly influenced circulating miRNAs (c-miRNAs) profiles of plasma in rainbow trout, which reveals the high potential of c-miRNAs, as physiologically relevant biomarker candidates of fish behavioral plasticity. Abstract Physical enrichment is known to improve living conditions of fish held in farming systems and has been shown to promote behavioral plasticity in captive fish. However, the brain’s regulatory-mechanism systems underlying its behavioral effects remain poorly studied. The present study investigated the impact of a three-month exposure to an enriched environment (EE vs. barren environment, BE) on the modulation of brain function in rainbow trout (Oncorhynchus mykiss) juveniles. Using high-throughput RT-qPCR, we assessed mRNA genes related to brain function in several areas of the trout brain. These included markers of cerebral activity and plasticity, neurogenesis, synaptogenesis, or selected neurotransmitters pathways (dopamine, glutamate, GABA, and serotonin). Overall, the fish from EE displayed a series of differentially expressed genes (neurotrophic, neurogenesis, and synaptogenesis markers) essentially localized in the telencephalon, which could underpin the beneficial effects of complexifying the environment on fish brain plasticity. In addition, EE significantly affected blood plasma c-miRNA signatures, as revealed by the upregulation of four c-miRNAs (miR-200b/c-3p, miR-203a-3p, miR-205-1a-5p, miR-218a-5p) in fish blood plasma after 185 days of EE exposure. Overall, we concluded that complexifying the environment through the addition of physical structures that stimulate and encourage fish to explore promotes the trout’s brain function in farming conditions.

Abstract
Sense of smell is mediated by diverse families of olfactory sensing receptors, conveying important dietary information, fundamental for growth and survival. The aim of this study was to elucidate the role of the sensory olfactory pathways in the regulation of feeding behavior of carnivorous rainbow trout (RT, Oncorhynchus mykiss), from first feeding until 8 months. Compared to a commercial diet, RT fed with a total plant-based diet showed drastically altered growth performance associated with feed intake from an early stage. Exhaustive examination of an RT genome database identified three vomeronasal type 1 receptor-like (ORA), 10 vomeronasal type 2 receptor-like (OLFC) and 14 main olfactory receptor (MOR) genes, all highly expressed in sensory organs, indicating their potential functionality. Gene expression after feeding demonstrated the importance in olfactory sensing perception of some OLFC (olfcg6) and MOR (mor103, -107, -112, -113, -133) receptor family genes in RT. The gene ora1a showed evidence of involvement in olfactory sensing perception for fish fed with a commercial-like diet, while ora5b, mor118, mor124 and olfch1 showed evidence of involvement in fish fed with a plant-based diet. Results indicated an impact of a plant-based diet on the regulation of olfactory sensing pathways as well as influence on monoaminergic neurotransmission in brain areas related to olfactory-driven behaviors. The overall findings suggest that feeding behavior is mediated through olfactory sensing detection and olfactory-driven behavior pathways in RT.

Abstract
Indigenous Peoples experience disproportionately higher rates of problematic substance use. These problems are situated in a context of individual and intergenerational trauma from colonization, residential schools, and racist and discriminatory practices, policies, and services. Therefore, substance use interventions need to adopt a trauma-informed approach. We aimed to synthesize and report the current literature exploring the intersection of trauma and substance use interventions for Indigenous Peoples. Fourteen databases were searched using keywords for Indigenous Peoples, trauma, and substance use. Of the 1373 sources identified, 117 met inclusion criteria. Literature on trauma and substance use with Indigenous Peoples has increased in the last 5 years (2012-2016, n = 29; 2017-2021, n = 48), with most literature coming from the United States and Canada and focusing on historical or intergenerational trauma. Few articles focused on intersectional identities such as 2SLGBTQIA+ (n = 4), and none focused on veterans. There were limited sources (n = 25) that reported specific interventions at the intersection of trauma and substance use. These sources advocate for multi-faceted, trauma-informed, and culturally safe interventions for use with Indigenous Peoples. This scoping review illuminates gaps in the literature and highlights a need for research reporting on trauma-informed interventions for substance use with Indigenous Peoples.

Abstract
STUDY QUESTION Can preimplantation genetic testing for aneuploidy (PGT-A) improve the live birth rate in patients with recurrent pregnancy loss (RPL)? SUMMARY ANSWER PGT-A use was associated with improved live birth rates in couples with recurrent pregnancy loss undergoing frozen embryo transfer (IVF-FET). WHAT IS KNOWN ALREADY Euploid embryo transfer is thought to optimize outcomes in some couples with infertility. There is insufficient evidence, however, supporting this approach to management of recurrent pregnancy loss. STUDY DESIGN, SIZE, DURATION This study included data collected by the Society of Assisted Reproductive Technologies Clinical Outcomes Reporting System (SART-CORS) for IVF-FET cycles between years 2010 through 2016. A total of 12 631 FET cycles in 10 060 couples were included in this analysis designed to assess the utility of PGT-A in couples with RPL undergoing FET, including 4287 cycles in couples with tubal disease who formed a control group. PARTICIPANTS/MATERIALS, SETTING, METHODS The experimental group included couples with RPL (strictly defined as a history of 3 or more pregnancy losses) undergoing FET with or without PGT-A. The primary outcome was live birth rate. Secondary outcomes included rates of clinical pregnancy, spontaneous abortion, and biochemical pregnancy loss. Differences were analyzed using generalized estimating equations logistic regression models to account for multiple cycles per patient. Covariates included in the model were age, gravidity, geographic region, race/ethnicity, smoking history, and indication for assisted reproductive technologies. Analyses were stratified for age groups as defined by SART: <35 years, 35-37 years, 38-40 years, 41-42 years, and >42 years. MAIN RESULTS AND THE ROLE OF CHANCE In women with a diagnosis of RPL, the adjusted odds ratio (OR) comparing IVF-FET with PGT-A versus without PGT-A for live birth outcome was 1.31 (95% CI: 1.12, 1.52) for age <35 years, 1.45 (95% CI: 1.21, 1.75) for ages 35-37 years, 1.89 (95% CI: 1.56, 2.29) for ages 38-40, 2.62 (95% CI: 1.94-3.53) for ages 41-42, and 3.80 (95% CI: 2.52, 5.72) for ages >42 years. For clinical pregnancy, the OR was 1.26 (95% CI: 1.08, 1.48) for age <35 years, 1.37 (95% CI: 1.14, 1.64) for ages 35-37 years, 1.68 (95% CI: 1.40, 2.03) for ages 38-40 years, 2.19 (95% CI: 1.65, 2.90) for ages 41-42, and 2.31 (95% CI: 1.60, 3.32) for ages >42 years. Finally, for spontaneous abortion, the OR was 0.95 (95% CI: 0.74, 1.21) for age <35 years, 0.85 (95% CI: 0.65, 1.11) for ages 35-37 years, 0.81 (95% CI: 0.60, 1.08) for ages 38-40, 0.86 (95% CI: 0.58, 1.27) for ages 41-42, and 0.58 (95% CI: 0.32, 1.07) for ages >42 years. LIMITATIONS, REASONS FOR CAUTION The retrospective collection of data including only women with recurrent pregnancy loss undergoing FET presents a limitation of this study, and results may not be generalizable to all couples with recurrent pregnancy loss. Also, data regarding evaluation and treatment for RPL for the included women is unavailable. WIDER IMPLICATIONS OF THE FINDINGS This is the largest study to date assessing the utility of PGT-A in women with RPL. PGT-A was associated with improvement in live birth and clinical pregnancy in women with RPL, with the largest difference noted in the group of women with age greater than 42 years. Couples with RPL warrant counseling on all management options to reduce subsequent miscarriage, which may include IVF with PGT-A for euploid embryo selection. STUDY FUNDING/COMPETING INTEREST(S) There are no conflicts of interest to declare. TRIAL REGISTRATION NUMBER N/A.

Abstract
BACKGROUND Abdominal aortic aneurysm (AAA) primarily affects elderly men. The impact of sex on aneurysm development has been associated with an effect of sex hormones, through mechanisms that are not fully understood. This study aimed to examine the association between levels of sex hormones and the occurrence of AAA in elderly men. METHODS A prospective case-control study was conducted including 452, 65-year old men participating in screening for AAA, 2013-2019; 230 men with AAA and 222 men with an aortic diameter<30mm (controls). Questionnaires and blood samples were collected and stored consecutively. Serum levels of total testosterone, estradiol, progesterone, luteinizing hormone and sex hormone binding globulin were analyzed by electrochemiluminescent immunoassays. Multivariable logistic regression analysis was used to assess the association of sex hormones with AAA. RESULTS The median aneurysm diameter was 33mm. Men with AAA had higher estradiol and progesterone levels than controls (93pmol/L vs. 84pmol/L, p=.003 and 0.41nmol/L vs. 0.17nmol/L, p<.001). Testosterone levels were lower in men with AAA than in controls (13nmol/L vs. 14nmol/L, p=.026). AAA was associated with detectable levels of progesterone(OR 6.69, 95%CI 3.86-11.47), smoking(OR 5.26, 95%CI 3.12-8.85), coronary heart disease(OR 4.06, 95%CI 1.92-8.58) and body mass index>25(OR 2.26, 95%CI 1.34-3.82). CONCLUSION The observed higher levels of estradiol and progesterone in men with AAA, suggest an impact of sex hormones on aneurysm development. The association between progesterone levels and aortic diameter, stress the importance of focusing on the potential effect of this unconsidered female sex hormone on aneurysm formation.

Abstract
Purpose: We investigated associations between 1930's era records of mortgage lending discrimination (i.e., “redlining”), a present-day indicator of disinvestment (i.e., residential physical disorder), and tumor clinicopathologic features (stage, grade, subtype) and survival among women diagnosed with breast cancer in New Jersey. Methods: Historical, Home Owners' Loan Corporation (HOLC) data were recently geocoded from the University of Richmond's Digital Scholarship Lab. Risk grades of ‘A'/‘Best', ‘B'/‘Still Desirable', ‘C'/‘Definitely Declining', and ‘D'/‘Hazardous' – available for six metropolitan areas of New Jersey – were collapsed into C/D (‘redlined') and A/B (‘not redlined') for analyses. Sociodemographics (age, race, ethnicity, geocoded residential address, date of diagnosis), tumor features (stage at diagnosis, grade, subtype), and vital status (cause and date of death) were ascertained from the New Jersey State Cancer Registry for all primary, histologically-confirmed, invasive breast cancer cases diagnosed between 2008 and 2017, among female residents of a HOLC-graded area, who were ≥ 20 years at diagnosis (N = 11,980). Residential physical disorder was estimated based on residential address at diagnosis using spatial prediction models of virtually audited Google Street View scenes of 6,132 locations. Logistic regression models of tumor features and accelerated failure time models of survival time to BrCa-specific death (follow-up through 2019) were built to investigate associations with redlining and physical disorder, while controlling for covariates. Results: There were 1,215 BrCa-specific deaths, a median follow-up time of 5.1 years, and a 5-year survival of 89.6%. Living in a historically redlined neighborhood was associated with higher odds of late-stage and high-grade tumors. Living in a non-redlined neighborhood was associated with a 47.5% (95% CI: 20.1, 79.8) longer survival time in low physical disorder areas. This survival benefit decreased as physical disorder increased. Conclusions: Historical racial housing discrimination might interact with present-day measures of disinvestment to influence BrCa survival. Future studies should collect more comprehensive data including potential confounders and residential history.

Abstract
INTRODUCTION Cancer has been associated with increased oxidative stress and deregulation of bioactive oxylipins derived from long-chain polyunsaturated fatty acids (LC-PUFA) like arachidonic acid (AA). There is a debate whether ω-3 LC-PUFA could promote or prevent prostate tumor growth through immune modulation and reduction of oxidative stress. Our aim was to study the association between enzymatically or non-enzymatically produced oxidized-LC-PUFA metabolites and tumor growth in an immune-competent eugonadal and castrated C57BL/6 male mice injected with TRAMP-C2 prostate tumor cells, fed with ω-3 or ω-6 LC-PUFA-rich diets. MATERIALS AND METHODS Tumor fatty acids were profiled by gas chromatography and 26 metabolites derived from either AA, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) were assessed by liquid chromatography-mass spectrometry. RESULTS The enriched ω-3 diet did not reduce oxidative stress overall in tumors but favored the formation of ω-3 rather than ω-6 derived isoprostanoids. We discovered that EPA and its oxidized-derivatives like F3-isoprostanes and prostaglandin (PG)F3α, were inversely correlated with tumor volume (spearman correlations and T-test, p<0.05). In contrast, F2-isoprostanes, adrenic acid, docosapentaenoic acid (DPAω-6) and PGE2 were positively correlated with tumor volume. Interestingly, F4-neuroprostanes, PGD2, PGF2α, and thromboxane were specifically increased in TRAMP-C2 tumors of castrated mice compared to those of eugonadal mice. DISCUSSION Decreasing tumor growth under ω-3 diet could be attributed in part to increased levels of EPA and its oxidized-derivatives, a reduced level of pro-angiogenic PGE2 and increased levels of F4-neuroprostanes and resolvins content in tumors, suspected of having anti-proliferative and anti-inflammatory effects.

Abstract
Characterization and modulation of cerebral function by ω-3 long chain polyunsaturated fatty acids (ω-3 LC-PUFAs), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) enrichment in plant based-diet were studied in rainbow trout (Oncorhynchus mikyss). We hypothesized that ω-3 LC-PUFAs are involved in the regulation of cerebral function in fish. During nine weeks, we examined the growth performance of rainbow trout for three experimental plant based-diets containing distinct levels of EPA and DHA. Using RT-qPCR, we assessed mRNA genes related to feeding behavior regulated by the central nervous system of humans, rodents and fish. These include markers of neuropeptides, indicators of cellular specification, animal stress, oxidant status, cytokines and genes regulating animal behaviour. ω-3 LC-PUFAs enrichment decreased daily food intake and induced a simultaneous mRNA expression increase in orexigenic transcript npy peptide and a decrease in anorexigen transcript pomcA peptide in the hypothalamus. Overall transcript genes related to proinflammatory cytokines, inflammation, antioxidant status, cortisol pathway, serotoninergic pathways and dopaminergic pathways were down-regulated in the juveniles fed the high ω-3 LC-PUFAs diet. However, the mRNA expression of transcripts related to cell specification were down regulated, namely tmem119 markers of microglial cell in forebrain and midbrain, gfap markers of astrocyte in the midbrain, and rbfox3 markers of neurons in the midbrain and hindbrain in juveniles fed high ω-3 experimental diet. In conclusion, this study revealed that a diet rich in ω-3 LC-PUFAs affected a relatively high proportion of the brain function in juvenile rainbow trout through mechanisms comparable to those characterized previously in mammals.

Abstract
Brain functions are known to be mainly modulated by adequate dietary intake. Inadequate intake as can be an excess or significant deficiency affect cognitive processes, behavior, neuroendocrine functions and synaptic plasticity with protective or harmful effects on neuronal physiology. Lipids, in particular, ω-6 and ω-3 long chain polyunsaturated fatty acids (LC-PUFAs) play structural roles and govern the different functions of the brain. Hence, the goal of this study was to characterize the whole brain fatty acid composition (precursors, enzymatic and non-enzymatic oxidation metabolites) of fish model of rainbow trout fed with three experimental plant-based diet containing distinct levels of eicosapentaenoic acid (EPA, 20:5 ω-3) and docosahexaenoic acid (DHA, 22:6 ω-3) (0% for low, 15.7% for medium and 33.4% for high, total fatty acid content) during nine weeks. Trout fed with the diet devoid of DHA and EPA showed reduced brain content of total ω-3 LC-PUFAs, with diminution of EPA and DHA. Selected enzymatic (cyclooxygenases and lipoxygenases) oxidation metabolites of arachidonic acid (AA, 20:4 ω-6) decrease in medium and high ω-3 LC-PUFAs diets. On the contrary, total selected enzymatic oxidation metabolites of DHA and EPA increased in high ω-3 LC-PUFAs diet. Total selected non-enzymatic oxidation metabolites of DHA (not detected for EPA) increased in medium and high ω-3 LC-PUFAs diets. In conclusion, this work revealed for the first time in fish model the presence of some selected enzymatic and non-enzymatic oxidation metabolites in brain and the modulation of brain lipid content by dietary DHA and EPA levels.

Abstract
Abstract
Introduction
Research suggests that young athletes may present different levels of perfectionism, which affect sport and academic performances. Sleep is also a variable that can affects grades. The aim of the present study was to investigate the relationship between personal standards (PS) perfectionism, sleep and school performance in young athletes.
Methods
27 young athletes (13-16y) wore an actigraph for a week and completed an adapted version of the Frost Multidimensional Perfectionism Scale at the beginning, middle and end of the school year. Sleep habits during weekdays (WD) and weekends (WE), and social jetlag (SJ) were extracted from the actigraphy. Mean performance of the two main school subjects were taken from the final report at the end of the school year (Mgrades). A linear regression was done between PS and Mgrades. Then, we used Hayes’ PROCESS Macro V3.4 to examine the role of sleep as a moderator of the relation between PS and Mgrades.
Results
PS significantly predicts Mgrades (β=.59, p=.001; Ra2=.34, p=.001). The addition of the interactions terms, first between SJ and PS, then, between WE bedtimes and PS, and finally, between WE waketimes and PS, explained a significant increase in variance in Mgrades (ΔR2=.14, F(1,23)=31.81, p<.001; ΔR2=.17, F(1,23)=25.99, p<.001; ΔR2=.10, F(1,23)=12.43, p=.002, respectively). Therefore, when SJ is higher than 39min, WE bedtimes are after 10:21PM and WE waketimes are after 7:12AM, PS and Mgrades are significantly related.
Conclusion
These results show that when higher SJ and later WE bedtimes and waketimes are present, low PS are associated with low grades and high PS are associated with high grades. In contrast, when a small SJ, earlier WE bedtimes and waketimes are present, PS are not associated with grades. These results suggest that young athletes may be more vulnerable to the effect of sleep disturbances on grades depending on various factors such as perfectionism.

Abstract
Abstract
Introduction
Recent studies have shown that chronotype is associated with personality in adolescents. Other studies suggest that athletes are more conscientious, and that this personality trait is associated with higher academic performance among adolescents. The aim of the present study was to investigate the relationship between personality, chronotype and academic performance in young athletes.
Methods
27 young athletes and 13 young non-athletes (13-16y) completed the Horne & Östberg Morningness-Eveningness Questionnaire (MEQ) and the NEO-PI-3. Grades were taken from their final report at the end of the school year (Mgrades=year-mean performance on the two main school subjects). First, T-tests were conducted to compare both groups on personality traits. Then, a moderation analysis was conducted using Hayes’ PROCESS Macro V3.4 to examine the moderation effect of the chronotype on the relationship between conscientiousness and Mgrades.
Results
Results show that young athletes are significantly more conscientious (M=4748±11,67) than non-athletes (M=38,31±9,59) (t(38)=2,46,p=.019). Conscientiousness and chronotype were entered in a regression analysis to predict Mgrades. The addition of the interaction term between chronotype and conscientiousness, to the regression analysis, explained a significant increase in variance in Mgrades (ΔR2=.34, F(1,23)=19.38, p<.001). Therefore, when the score is inferior to 57.75 at the MEQ (toward evening type), conscientiousness and Mgrades are significantly related (β=0.28, t(23)=2.07, p=0.05).
Conclusion
These results show that the chronotype moderates the relationship between conscientiousness and academic performance in young athletes. Specifically, in more evening types, higher level of conscientiousness is associated with higher grades and lower level of conscientiousness is associated with lower grades. On the other hand, for more morning types, the level of conscientiousness is not associated with grades. These results suggest that conscientiousness may be a protective factor against the impacts of adolescence sleep changes and disturbances, on academic performance.

Abstract
A trait of inflammation pathogenesis in human atherosclerosis: inflammasome driven interleukin-1 signalling in complex atherosclerotic plaques via hyperlipidemia trained innate immunity
Objectives
We aimed to investigate interleukin (IL)-1 generation and the regulatory role of inflammasome in human advanced atherosclerosis.
Background
IL-1β is key contributor to the inflammatory process associated with atherosclerosis and its complications. Recent studies suggested that IL-1β blockade reduces the burden of inflammation and recurrence of cardiovascular events. Yet, other cytokines in IL-1 family and the regulation of IL-1 generation in patients with atherosclerosis remains poorly understood.
Methods and results
A focused transcriptomic analysis in human atherosclerotic specimens discovered that human atherosclerotic plaques host a broad reservoir of inflammasome components, characterised by expression of canonical inflammasome gene NLRP6, NLRP12, NLRC4, NLRP3 and non-canonical inflammasome gene caspase 4 significantly elevated in the symptomatic plaques versus the asymptomatic plaques. Upregulation of NLRP3 inflammasome expression in plaque validated by immunohistochemistry staining suggested it as a distinctive characteristic of plaque vulnerability and complexity. Functional studies on atherosclerotic explants obtained from patients undergoing carotid endarterectomy revealed constitutive generation of IL-1β accompanied by secretion of comparable levels of IL-1α from the majority of the plaques, while IL-18 and IL-33 generation from some of the plaques. Stimulation of the plaques with inflammasome activators showed an inducible generation of both IL-1α and IL-1β, not IL-18 or IL-33, mediated by specific canonical and non-canonical inflammasome pathways. Analysis on the medication records of these patients indicated that plaques from patients with suboptimally controlled hyperlipidemia, imaging signs for plaque instability and inadequate statins therapy possessed higher recruitable production of IL-1β, suggesting the conventional atherogenic factor in regulation of inflammasome immunity and disease activity. Mechanistic studies on tissue and cells isolated from atheromatous plaques demonstrate that generation of mature IL-1β is via a mechanism controlled by NLRP3 and the effector caspase-1.
Conclusions
The study supports a profound canonical and non-canonical inflammasomes mediated plaque IL-1α/β generation, via a key mechanism by NLRP3 and caspase-1. The results provide biological insights into the clinical merit of high-intensity cholesterol lowering and anti-IL-1 signalling-directed therapies in high-risk patients with atherosclerosis.

Abstract
Neuromyelitis Optica (NMO) previously known as Devic disease is inflammatory disorder of central nervous system characterized by severe immune mediated demyelination and axonal damage predominating targeting optic nerves and spinal cord leading to blindness and paralysis. The spectrum of the disease has expanded based on the specificity of the autoimmune response to the aquaporin-4 (AQP-4) water channel expressed on the end feet of astrocytes in the central nervous system. The coordinated immunological attack against aquaporin-4 is mediated by B & T cells, innate cells including neutrophils and eosinophils and complement system as well as pathogenic antibodies.

Abstract
Moderate-to-severe tricuspid regurgitation is associated with higher mortality and morbidity yet remains significantly undertreated. The reasons for this are complex but include a higher operative mortality for patients undergoing isolated tricuspid valve surgery. This study sought to determine the prevalence of patients with moderate-to-severe tricuspid regurgitation and identify those who could be potentially suitable for percutaneous tricuspid valve intervention by screening patients referred for transthoracic echocardiography (ECHO) at a tertiary center. Our results showed that the prevalence of moderate-to-severe tricuspid regurgitation in our total ECHO patient population was 2.8%. Of these, approximately 1 in 8 patients with moderate-to-severe tricuspid regurgitation would be potentially suitable for percutaneous intervention, and suggests a large, unmet clinical need in this population.

Abstract
Dissociative (conversion) disorder (DCR) has a long and controversial history. Some authors wish to classify it with somatoform disorders separate from dissociative disorders; many researchers keep it with DCR. Symptoms pattern also varies in different cultures. This study used the criteria of International Classification of Diseases Tenth Edition (ICD-10). Study was aimed to see the presenting symptom profile of dissociative (conversion) disorder more focusing on psychotic symptoms in tertiary care hospital in Bangladesh. This cross sectional observation was carried out in two different tertiary care hospitals in Dhaka city with preformed pretested questionnaire. Data were collected from 100 consecutive patients from July 2005 to June 2006 and data were analyzed by Statistical Package of Social Science (SPSS) 16.0. Pattern of dissociative (conversion) disorder indicated that symptoms presentations are different in Bangladesh which is difficult to categorize using existing criteria of ICD-10. Among 100 consecutive patients diagnosed as dissociative (conversion) disorder 13 patients had psychotic symptoms. Psychotic presentation of conversion disorder often creates doubts among the clinicians. Careful history taking, identifying the underlying psychosocial stressors will help clinicians to diagnose them accurately. It should be noted that the pattern of presentation in South Asia may be different due to role of culture on symptoms presentation in this region.

Abstract
Background The aim of this study was to develop a 48‐h mortality risk score, which included morphology data, for patients with ruptured abdominal aortic aneurysm presenting to an emergency department, and to assess its predictive accuracy and clinical effectiveness in triaging patients to immediate aneurysm repair, transfer or palliative care. Methods Data from patients in the IMPROVE (Immediate Management of the Patient With Ruptured Aneurysm: Open Versus Endovascular Repair) randomized trial were used to develop the risk score. Variables considered included age, sex, haemodynamic markers and aortic morphology. Backwards selection was used to identify relevant predictors. Predictive performance was assessed using calibration plots and the C‐statistic. Validation of the newly developed and other previously published scores was conducted in four external populations. The net benefit of treating patients based on a risk threshold compared with treating none was quantified. Results Data from 536 patients in the IMPROVE trial were included. The final variables retained were age, sex, haemoglobin level, serum creatinine level, systolic BP, aortic neck length and angle, and acute myocardial ischaemia. The discrimination of the score for 48‐h mortality in the IMPROVE data was reasonable (C‐statistic 0·710, 95 per cent c.i. 0·659 to 0·760), but varied in external populations (from 0·652 to 0·761). The new score outperformed other published risk scores in some, but not all, populations. An 8 (95 per cent c.i. 5 to 11) per cent improvement in the C‐statistic was estimated compared with using age alone. Conclusion The assessed risk scores did not have sufficient accuracy to enable potentially life‐saving decisions to be made regarding intervention. Focus should therefore shift to offering repair to more patients and reducing non‐intervention rates, while respecting the wishes of the patient and family. Not much help

Abstract
Substance Use Disorder is a frequent problem in Bangladesh and many of these patients develop psychosis. Substance use can cause psychosis and it can modify the course of psychosis. This cross-sectional study was done to see the proportion of substance use in patients with First-Episode Psychosis (FEP) in two tertiary care hospitals in Dhaka, Bangladesh mentioned here as Bangabandhu Sheikh Mujib Medical University and Dhaka Medical College Hospital; from November 2007 March 2009. Fifty consecutive FEP patients were taken as subjects and 50 healthy attendants were recruited as control. Mean age of the patients was 27.24, male (62%) are more having first-episode psychosis than female (38%). Majority of the patients were unmarried (64%). Regarding occupation students were 34%, followed by unemployed 24% and service18%. In control group's occupation; service 34%, housewife 22%. Life time substance use was found double in patients with first-episode psychosis than control. Cannabis was found to be the most common substance causing psychosis. Among the lifetime substance users in fist-episode psychosis patients 77.78% were male where as, in control group 100% patients were male. However, the researcher did not find any of the first-episode psychosis patients taking current use of substance (abuse and /or dependence). The small size of the present study was only 50. Future prospective study is required having large sample size to see the outcome of substance use in first-episode psychosis.

Abstract
ω3 Polyunsaturated fatty acids (ω3 PUFAs) have several biological properties including anti-arrhythmic effects. However, there are some evidences that it is not solely ω3 PUFAs per se that are biologically active but the non-enzymatic oxygenated metabolites of polyunsaturated fatty acids (NEO-PUFAs) like isoprostanes and neuroprostanes. Recent question arises how these molecules take part in physiological homeostasis, show biological bioactivities and anti-inflammatory properties. Furthermore, they are involved in the circulations of childbirth, by inducing the closure of the ductus arteriosus. In addition, oxidative stress which can be beneficial for the heart in given environmental conditions such as the presence of ω3 PUFAs on the site of the stress and the signaling pathways involved are also explained in this review.

Abstract
BACKGROUND Microglia are the main resident immunological cells of the central nervous system (CNS) that are functionally equivalent to macrophages. However, due to the cellular heterogeneity of the brain, it is technically challenging to obtain highly specific, healthy microglia with the desired phenotype in sufficient yield for in vivo experiments. NEW METHOD This study presents a new and easy method for the isolation of microglia cells from mouse pups (P1-P3). This method consists of a 20-day protocol, divided in three sections: mixed cell culture, culture maintaining (astrocytes growing), and isolation after astrocytes confluence. RESULTS This procedure produces microglia with no astrocyte, neuron and oligodendrocyte precursors cells contamination that are functionally active to answer inflammatory responses based on the measurement of cell and inflammatory markers. This technique requires approximately three hours for the isolation of neonatal mixed cell culture, 20 to 22 days for microglia growing and two days before starting experiments from pure and healthy microglia. COMPARISON WITH EXISTING METHODS AND CONCLUSIONS This study presents an isolation protocol that is adapted from existing methods and is economic, rapid, not tedious, with little manipulation time and work. This method also allows to isolate large amount of high specific microglia cells with no specific phenotype and with great reproducibility and efficiently. This study provides a detailed description of the methods that is routinely used in our laboratory for the isolation and the culture of microglia, with emphasis on the steps that are deemed most critical for obtaining large amount of pure and healthy cultures.

Abstract
BACKGROUND Most people with stroke in India have no access to organised rehabilitation services. The effectiveness of training family members to provide stroke rehabilitation is uncertain. Our primary objective was to determine whether family-led stroke rehabilitation, initiated in hospital and continued at home, would be superior to usual care in a low-resource setting. METHODS The Family-led Rehabilitation after Stroke in India (ATTEND) trial was a prospectively randomised open trial with blinded endpoint done across 14 hospitals in India. Patients aged 18 years or older who had had a stroke within the past month, had residual disability and reasonable expectation of survival, and who had an informal family-nominated caregiver were randomly assigned to intervention or usual care by site coordinators using a secure web-based system with minimisation by site and stroke severity. The family members of participants in the intervention group received additional structured rehabilitation training-including information provision, joint goal setting, carer training, and task-specific training-that was started in hospital and continued at home for up to 2 months. The primary outcome was death or dependency at 6 months, defined by scores 3-6 on the modified Rankin scale (range, 0 [no symptoms] to 6 [death]) as assessed by masked observers. Analyses were by intention to treat. This trial is registered with Clinical Trials Registry-India (CTRI/2013/04/003557), Australian New Zealand Clinical Trials Registry (ACTRN12613000078752), and Universal Trial Number (U1111-1138-6707). FINDINGS Between Jan 13, 2014, and Feb 12, 2016, 1250 patients were randomly assigned to intervention (n=623) or control (n=627) groups. 33 patients were lost to follow-up (14 intervention, 19 control) and five patients withdrew (two intervention, three control). At 6 months, 285 (47%) of 607 patients in the intervention group and 287 (47%) of 605 controls were dead or dependent (odds ratio 0·98, 95% CI 0·78-1·23, p=0·87). 72 (12%) patients in the intervention group and 86 (14%) in the control group died (p=0·27), and we observed no difference in rehospitalisation (89 [14%]patients in the intervention group vs 82 [13%] in the control group; p=0·56). We also found no difference in total non-fatal events (112 events in 82 [13%] intervention patients vs 110 events in 79 [13%] control patients; p=0·80). INTERPRETATION Although task shifting is an attractive solution for health-care sustainability, our results do not support investment in new stroke rehabilitation services that shift tasks to family caregivers, unless new evidence emerges. A future avenue of research should be to investigate the effects of task shifting to health-care assistants or team-based community care.

Abstract
It has been 60 yr since the discovery of reactive oxygen species (ROS) in biology and the beginning of the scientific community's attempt to understand the impact of the unpaired electron of ROS molecules in biological pathways, which was eventually noted to be toxic. Several studies have shown that the presence of ROS is essential in triggering or acting as a secondary factor for numerous pathologies, including metabolic and genetic diseases; however, it was demonstrated that chronic treatment with antioxidants failed to show efficacy and positive effects in the prevention of diseases or health complications that result from oxidative stress. On the contrary, such treatment has been shown to sometimes even worsen the disease. Because of the permanent presence of ROS in organisms, elaborate mechanisms to adapt with these reactive molecules and to use them without necessarily blocking or preventing their actions have been studied. There is now a large body of evidence that shows that living organisms have conformed to the presence of ROS and, in retrospect, have adapted to the bioactive molecules that are generated by ROS on proteins, lipids, and DNA. In addition, ROS have undergone a shift from being molecules that invoked oxidative damage in regulating signaling pathways that impinged on normal physiological and redox responses. Working in this direction, this review unlocks a new conception about the involvement of cellular oxidants in the maintenance of redox homeostasis in redox regulation of normal physiological functions, and an explanation for its essential role in numerous pathophysiological states is noted.-Roy, J., Galano, J.-M., Durand, T., Le Guennec, J.-Y., Lee, J.
