Abstract
Proteolysis-targeting chimeras (PROTACs) are an emerging therapeutic modality that show promise to open a target space not accessible to conventional small molecules via a degradation-based mechanism. PROTAC degraders, due to their bifunctional nature, which is categorized as 'beyond the Rule of Five', have gained attention as a distinctive therapeutic approach for oral administration in clinical settings. However, the development of PROTACs with adequate oral bioavailability remains a significant hurdle, largely due to their large size and less than ideal physical and chemical properties. This review encapsulates the latest advancements in orally delivered PROTACs that have entered clinical evaluation as well as developments highlighted in recent scholarly articles. The insights and methodologies elaborated upon in this review could be instrumental in supporting the discovery and refinement of novel PROTAC degraders aimed at the treatment of various human cancers.

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
The hormone receptor-positive (HR+) type is the most frequently identified subtype of breast cancer. HR+ breast cancer has a more positive prognosis when compared to other subtypes, such as human epidermal growth factor protein 2-positive disorder and triple-negative disease. The advancement in treatment outcomes for advanced HR+ breast cancer has been considerably elevated due to the discovery of cyclin-dependent kinase 4/6 inhibitors and their combination effects with endocrine therapy. However, despite the considerable effectiveness of tamoxifen, a selective estrogen receptor modulator (SERMs), and aromatase inhibitors (AI), the issue of treatment resistance still presents a significant challenge for HR+ breast cancer. As a result, there is a focus on exploring new therapeutic strategies such as targeted protein degradation and covalent inhibition for targeting ERα. This article discusses the latest progress in treatments like oral selective ER degraders (SERDs), complete estrogen receptor antagonists (CERANs), selective estrogen receptor covalent antagonists (SERCAs), proteolysis targeting chimera (PROTAC) degraders, and combinations of CDK4/6 inhibitors with endocrine therapy. The focus is specifically on those compounds that have transitioned into phases of clinical development.

Abstract
Current clinical tests for Parkinson's disease (PD) provide insufficient diagnostic accuracy leading to an urgent need for improved diagnostic biomarkers. As microRNAs (miRNAs) are promising biomarkers of various diseases, including PD, this systematic review and meta-analysis aimed to assess the diagnostic accuracy of biofluid miRNAs in PD. All studies reporting data on miRNAs expression in PD patients compared to controls were included. Gene targets and significant pathways associated with miRNAs expressed in more than 3 biofluid studies with the same direction of change were analyzed using target prediction and enrichment analysis. A bivariate model was used to calculate sensitivity, specificity, likelihood ratios, and diagnostic odds ratio. While miR-24-3p and miR-214-3p were the most reported miRNA (7 each), miR-331-5p was found to be consistently up regulated in 4 different biofluids. Importantly, miR-19b-3p, miR-24-3p, miR-146a-5p, and miR-221-3p were reported in multiple studies without conflicting directions of change in serum and bioinformatic analysis found the targets of these miRNAs to be associated with pathways important in PD pathology. Of the 102 studies from the systematic review, 15 studies reported sensitivity and specificity data on combinations of miRNAs and were pooled for meta-analysis. Studies (17) reporting sensitivity and specificity data on single microRNA were pooled in a separate meta-analysis. Meta-analysis of the combinations of miRNAs (15 studies) showed that biofluid miRNAs can discriminate between PD patients and controls with good diagnostic accuracy (sensitivity = 0.82, 95% CI 0.76-0.87; specificity = 0.80, 95% CI 0.74-0.84; AUC = 0.87, 95% CI 0.83-0.89). However, we found multiple studies included more males with PD than any other group therefore possibly introducing a sex-related selection bias. Overall, our study captures key miRNAs which may represent a point of focus for future studies and the development of diagnostic panels whilst also highlighting the importance of appropriate study design to develop representative biomarker panels for the diagnosis of PD.

Abstract
Pancreatic cancer cells adapt to nutrient-scarce metabolic conditions by increasing their oxidative phosphorylation reserve to survive. Here, we present a first-in-class small-molecule NDUFS7 antagonist that inhibits oxidative phosphorylation (OXPHOS) for the treatment of pancreatic cancer. The lead compound, DX2-201, suppresses the proliferation of a panel of cell lines, and a metabolically stable analogue, DX3-213B, shows significant efficacy in a syngeneic model of pancreatic cancer. Exome sequencing of six out of six clones resistant to DX2-201 revealed a pV91M mutation in NDUFS7, providing direct evidence of its drug-binding site. In combination studies, DX2-201 showed synergy with multiple metabolic modulators, select OXPHOS inhibitors, and PARP inhibitors. Importantly, a combination with 2-deoxyglucose overcomes drug resistance in vivo. This study demonstrates that an efficacious treatment for pancreatic cancer can be achieved through inhibition of OXPHOS and direct binding to NDUFS7, providing a novel therapeutic strategy for this hard-to-treat cancer.

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
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
Sigma 2 receptor (σ2R) is overexpressed in select cancers and is regarded as a biomarker for tumor proliferation. σ2R ligands are emerging as promising theranostics for cancer and neurodegenerative diseases. Herein, we describe the design and synthesis of a series of novel quinolyl pyrazinamides as selective and potent σ2R ligands that show sub-micromolar potency in pancreatic cancer cell lines. Compounds 14 (JR1-157) and 17 (JR2-298) bind σ2R with Ki of 47 and 10 nM, respectively. Importantly, compound 14 has an oral bioavailability of 60% and shows significant in vivo efficacy without obvious toxicity in a syngeneic model of pancreatic cancer. The cytotoxicity of the quinolyl pyrazinamides significantly enhanced in the presence of copper and diminished in the presence of the copper-chelator tetrathiomolybdate. In conclusion, compound 14 is water-soluble, metabolically stable, orally active, and increases the expression of the autophagy marker LC3B and warrants further development for the treatment of pancreatic cancer.

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
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
Targeting oxidative phosphorylation (OXPHOS) complexes is an emerging strategy to disrupt the metabolism of select cancer subtypes and to overcome resistance to targeted therapies. Here, we describe our lead optimization campaign on a series of benzene-1,4-disulfonamides as novel OXPHOS complex I inhibitors. This effort led to the discovery of compound 23 (DX3-213B) as one of the most potent complex I inhibitors reported to date. DX3-213B disrupts adenosine triphosphate (ATP) generation, inhibits complex I function, and results in the growth inhibition of pancreatic cancer cells in the low nanomolar range. Importantly, the oral administration of DX3-213B resulted in significant in vivo efficacy in a pancreatic cancer syngeneic model without obvious toxicity. Our data clearly demonstrate that OXPHOS inhibition can be a safe and efficacious strategy to treat pancreatic cancer.

Abstract
Inhibition of oxidative phosphorylation (OXPHOS) is a promising therapeutic strategy for select cancers that are dependent on aerobic metabolism. Here, we report the discovery, optimization, and structure-activity relationship (SAR) study of a series of novel OXPHOS inhibitors. The hit compound, benzene-1,4-disulfonamide 1, was discovered in a phenotypic screen selective for cytotoxicity in a galactose-containing medium. Our multi-parameter optimization campaign led to the discovery of 65 (DX3-235), showing nanomolar inhibition of complex I function and adenosine triphosphate (ATP) production in a galactose-containing medium resulting in significant cytotoxicity. Importantly, 64 (DX3-234), a close analogue of 65, is well tolerated in mice and shows significant single agent efficacy in a Pan02 syngeneic pancreatic cancer model, suggesting that highly potent and selective OXPHOS inhibitors can be useful for the treatment of pancreatic cancer.

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
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
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
BACKGROUND The primitive trigeminal artery (PTA) is the most common and the largest persistent carotid-basilar anastomosis. Primitive trigeminal artery variants (PTAVs) are anastomoses between the internal carotid artery and cerebellar arteries. These vessels pose a risk of hemorrhagic or ischemic complications during neurosurgical procedures in the parasellar and intrasellar regions. The aim of this study was to determine the prevalence of both PTA and PTAVs and their clinically important anatomic features. METHODS Major electronic databases were thoroughly searched for studies on PTA and PTAV. References in the included articles were also evaluated. Data regarding prevalence, laterality, origin, course patterns, and associated anomalies were extracted and pooled into a meta-analysis. RESULTS A total of 39 studies (110,866 patients) were included in the meta-analysis. The total pooled prevalence estimate of PTA and PTAVs combined was 0.4% (95% confidence interval [CI], 0.3-0.5). Individually, PTA was present in 0.3% of patients and PTAV in 0.2%. Both arteries most often originated from the C4 internal carotid artery and took a course lateral to the dorsum sellae. The anterior inferior cerebellar artery type was the predominant PTAV (72.1%). Basilar artery hypoplasia was found in 42.5% of patients with a PTA. CONCLUSIONS PTA and PTAVs are rare vessels, but they are clinically important because they can contribute to trigeminal neuralgia. Knowledge of the potential course of these arteries is essential in neuroradiology and neurosurgery, especially in minimally invasive procedures such as the endoscopic endonasal transsphenoidal approach to the pituitary gland and the percutaneous gasserian ganglion procedure.

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
Sex- and gender-based differences need to be considered in evidence-based medical research as there are anatomical and physiological differences between males and females. Females are underrepresented in studies, with results from males often generalized to both sexes. The Sex and Gender Equity in Research (SAGER) guidelines were published in 2016 to address sex- and gender-bias in research. Correct understanding and appropriate use of the terms "sex" and "gender" are essential. These terms are discussed in an anatomical context and recommendations are made as to how the SAGER guidelines can guide the reporting of anatomical studies to minimize the risk of reporting bias.

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
No new and effective treatments have been approved for the treatment of esophageal squamous cell carcinoma (ESCC) in the past decade. Cisplatin and 5-fluoruracil are the most commonly used drugs for this disease. In order to develop a new class of drugs effective in our ESCC phenotypic screens, we began a systematic approach to generate novel compounds based on the 2-oxo-1,2-dihydroquinoline-4-carboxamide fragment. Herein, we report on the synthesis and initial assessment of 55 new analogues in two ESCC cell lines. Some of the active analogues with IC50 values around 10 μM were tested in three additional cell lines. Our structure-activity relationships revealed remarkable alterations in the anti proliferative activities upon modest chemical modifications and autophagy modulation is a suggested mechanism of action.

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
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
Imatinib mesylate (IM) therapy has been shown to induce lower T cell counts in chronic myelogenous leukemia (CML) patients and an interference of IM with T cell receptor (TCR) signaling has been invoked to explain this observation. However, IL-7 and TCR signaling are both essential for lymphocyte survival. This study was undertaken to determine whether IM interferes with IL-7 or TCR signaling to explain lower T cell counts in patients. At diagnosis, CML patients have typically lower CD4+ counts in their blood, yet CD8+ counts are normal or even increased in some. Following the initiation of IM treatment, CD4+ counts were further diminished and CD8+ T lymphocytes were dramatically decreased. In vitro studies confirmed IM interference with TCR signaling through the inhibition of ERK phosphorylation and we showed a similar effect on IL-7 signaling and STAT5 phosphorylation (STAT5-p). Importantly however, using an in vivo mouse model, we demonstrated that IM impaired T cell survival through the inhibition of IL-7 and STAT5-p but not TCR signaling which remained unaffected during IM therapy. Thus, off-target inhibitory effects of IM on IL-7 and STAT5-p explain how T cell lymphopenia occurs in patients treated with IM.
