Abstract
We study fluctuations of the local energy cascade rate Φ_{ℓ} in turbulent flows at scales (ℓ) in the inertial range. According to the Kolmogorov refined similarity hypothesis (KRSH), relevant statistical properties of Φ_{ℓ} should depend on ε_{ℓ}, the viscous dissipation rate locally averaged over a sphere of size ℓ, rather than on the global average dissipation. However, the validity of KRSH applied to Φ_{ℓ} has not yet been tested from data. Conditional averages such as ⟨Φ_{ℓ}|ε_{ℓ}⟩ as well as of higher-order moments are measured from direct numerical simulations data, and results clearly adhere to the predictions from KRSH. Remarkably, the same is true when considering forward (Φ_{ℓ}>0) and inverse (Φ_{ℓ}<0) cascade events separately. Measured ratios of forward and inverse cascade probability densities conditioned on ε_{ℓ} also confirm the applicability of the KRSH to analysis of the fluctuation relation from nonequilibrium thermodynamics.

Abstract
INTRODUCTION Heart failure with impaired ejection fraction (HFIEF) represents the end-stage of most cardiac diseases, and is responsible for a high mortality rate. In order to identify patients at risk, numerous clinical and paraclinical prognostic factors have been proposed. The electrocardiogram (ECG), easy to perform and inexpensive, retains a powerful role in the prognostic evaluation of heart failure patients. The aim was to evaluate ECG signs associated with mortality in a retrospective cohort of patients with ICFEA. METHODOLOGY The study was observational and analytical based on retrospective data collected from patients benefiting from a primary hospitalization for ICFEA at the Abidjan Heart Institute from January 2018 to July 2020. RESULTS Of the 370 patients included, 197 had died by August 1, 2020, representing an overall mortality of 53%. Mortality progressed gradually up to one year, then remained unchanged up to 30 months. In multivariate Cox regression including ECG variables only, the presence of intra-ventricular conduction disorders (OR: 1.80; 95% CI [1.01-3.25]), microvoltage (OR: 1.82; 95% CI [1.05-16]), and pathological Q waves (OR: 1.70; 95% CI [1.02-2.83]), were significantly associated with overall mortality. When ECG variables and clinical, paraclinical and therapeutic demographic variables were included, only the presence of pathological Q waves (OR:1.74; 95% CI [1.01-3.01]) persisted as a risk factor for mortality. Hypertension and treatment of heart failure, in particular ACEI/ARII, beta-blockers and ARM, were protective factors. The presence of Q waves was associated with a significant reduction in survival, based on curves obtained using the Kaplan-Meier model. CONCLUSION ICFEA is responsible for high mortality, mainly in the year following the 1st hospitalization for cardiac decompensation. The presence of pathological Q waves is the only electrocardiographic sign that remains statistically associated with a poor prognosis, after adjustment.

Abstract
OBJECTIVE To evaluate the comparative efficacy and safety of glucagon-like peptide-1 receptor agonists (GLP-1RAs) on glycaemic control, body weight, and lipid profile in adults with type 2 diabetes. DESIGN Systematic review and network meta-analysis. DATA SOURCES PubMed, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), and Embase from database inception to 19 August 2023. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Eligible randomised controlled trials enrolled adults with type 2 diabetes who received GLP-1RA treatments and compared effects with placebo or any GLP-1RA drug, with a follow-up duration of at least 12 weeks. Trials with a crossover design, non-inferiority studies comparing GLP-1RA and other drug classes without a placebo group, using withdrawn drugs, and non-English studies were deemed ineligible. RESULTS 76 eligible trials involving 15 GLP-1RA drugs and 39 246 participants were included in this network meta-analysis; all subsequent estimates refer to the comparison with placebo. All 15 GLP-1RAs effectively lowered haemoglobin A1c and fasting plasma glucose concentrations. Tirzepatide induced the largest reduction of haemoglobin A1c concentrations (mean difference -2.10% (95% confidence interval -2.47% to -1.74%), surface under the cumulative ranking curve 94.2%; high confidence of evidence), and fasting plasma glucose concentrations (-3.12 mmol/L (-3.59 to -2.66), 97.2%; high confidence), and proved the most effective GLP-1RA drug for glycaemic control. Furthermore, GLP-1RAs were shown to have strong benefits to weight management for patients with type 2 diabetes. CagriSema (semaglutide with cagrilintide) resulted in the highest weight loss (mean difference -14.03 kg (95% confidence interval -17.05 to -11.00); high confidence of evidence), followed by tirzepatide (-8.47 kg (-9.68 to -7.26); high confidence). Semaglutide was effective in lowering the concentration of low density lipoprotein (-0.16 mmol/L (-0.30 to -0.02)) and total cholesterol (-0.48 mmol/L (-0.84 to -0.11)). Moreover, this study also raises awareness of gastrointestinal adverse events induced by GLP-1RAs, and concerns about safety are especially warranted for high dose administration. CONCLUSIONS GLP-1RAs are efficacious in treating adults with type 2 diabetes. Compared with the placebo, tirzepatide was the most effective GLP-1RA drug for glycaemic control by reducing haemoglobin A1c and fasting plasma glucose concentrations. GLP-1RAs also significantly improved weight management for type 2 diabetes, with CagriSema performing the best for weight loss. The results prompt safety concerns for GLP-1RAs, especially with high dose administration, regarding gastrointestinal adverse events. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42022342845.

Abstract
Objective: To understand the incubation periods of infections of Omicron variants BA.2 and BF.7 in two COVID-19 epidemics and related factors in Beijing and provide basic parameters for the establishment of 2019-nCoV dynamic transmission model. Methods: The COVID-19 cases with specific exposure time and onset time in the Omicron variant BA.2 infection epidemic in April 2022 and in the Omicron variant BF.7 infection epidemic in October 2022 in Beijing were included in the analysis. The rank-sum test was conducted to estimate the differences in the incubation period between two types of infections. The incubation period distribution of the Omicron variant infection was fitted by using Weibull, Gamma and lognormal distributions. Multivariate analysis of variance was conducted to assess the effects of age, sex, variant type and vaccination status on the incubation periods. Results: A total of 64 cases of variant BA.2 infection and 58 cases of variant BF.7 infection were included. The M(Q1,Q3) of the incubation period was 3.00 (3.00, 4.00) days for BA.2 infection and 3.00 (2.00, 3.25) days for BF.7 infection. The lognormal distribution was the best fit. Multivariate analysis of variance showed that there were some differences in the incubation periods between two types of infections of Omicron variants, and the incubation period of variant BF.7 infection was shorter than that of variant BA.2 infection. Conclusion: Omicron variant BF.7 infection had shorter incubation period compared with Omicron variant BA.2 infection.

Abstract
BACKGROUND Hypertension is a major risk factor for cardiovascular events. The cardiovascular risk assessment is performed using specific algorithms, particularly SCORE2 and SCORE2-OP developed by the European Society of Cardiology. PATIENTS AND METHODS Prospective cohort study from February 1, 2022, to July 31, 2022, enrolling 410 hypertensive patients. Epidemiological, paraclinical, therapeutic, and follow-up data were analyzed. Cardiovascular risk stratification of patients was performed using SCORE2 and SCORE2-OP algorithms. We compared the initial and 6-month cardiovascular risks. RESULTS The mean age of the patients was 60.88 ± 12.35 years with a female predominance (sex ratio = 0.66). In addition to hypertension, dyslipidemia (45.4%) was the most frequently associated risk factor. A high proportion of patients were classified as high (48.6%) and very high (46.3%) cardiovascular risk, with a significant difference between men and women. Reassessment of cardiovascular risk after 6 months of treatment found significant differences compared with the initial cardiovascular risk (p < 0.001). The rate of patients at low to moderate cardiovascular risk (49.5%) increased substantially, whereas the proportion of patients at very high risk decreased (6.8%). CONCLUSION Our study conducted at Abidjan Heart Institute in a young population of patients with hypertension revealed a severe cardiovascular risk profile. Almost half of the patients are classified at very high cardiovascular risk, based on the SCORE2 and SCORE2-OP. The widespread use of these new algorithms for risk stratification should lead to more aggressive management and prevention strategies for hypertension and associated risk factors.

Abstract
Ulcerative colitis (UC) has become a global epidemic, and the lack of an effective cure highlights the necessity and urgency to explore novel therapies. Sijunzi Decoction (SJZD), a classical Chinese herbal formula, has been comprehensively applied and clinically proven effective in treating UC; however, the pharmacological mechanism behind its therapeutic benefits is largely obscure. Here, we find that SJZD can restore microbiota homeostasis and intestinal barrier integrity in DSS-induced colitis. SJZD significantly alleviated the colonic tissue damage and improved the goblet cell count, MUC2 secretion, and tight junction protein expressions, which indicated enhanced intestinal barrier integrity. SJZD remarkedly suppressed the abundance of phylum Proteobacteria and genus Escherichia-Shigella, which are typical features of microbial dysbiosis. Escherichia-Shigella was negatively correlated with body weight and colon length, and positively correlated with disease activity index and IL-1[Formula: see text]. Furthermore, through gut microbiota depletion, we confirmed that SJZD exerted anti-inflammatory activities in a gut microbiota-dependent manner, and fecal microbiota transplantation (FMT) validated the mediating role of gut microbiota in the SJZD treatment of UC. Through gut microbiota, SJZD modulates the biosynthesis of bile acids (BAs), especially tauroursodeoxycholic acid (TUDCA), which has been identified as the signature BA during SJZD treatment. Cumulatively, our findings disclose that SJZD attenuates UC via orchestrating gut homeostasis in microbial modulation and intestinal barrier integrity, thus offering a promising alternative approach to the clinical management of UC.

Abstract
Background Probiotics play a vital role in treating immune and inflammatory diseases by improving intestinal barrier function; however, a comprehensive evaluation is missing. The present study aimed to explore the impact of probiotics on the intestinal barrier and related immune function, inflammation, and microbiota composition. A systematic review and meta-analyses were conducted. Methods Four major databases (PubMed, Science Citation Index Expanded, CENTRAL, and Embase) were thoroughly searched. Weighted mean differences were calculated for continuous outcomes with corresponding 95% confidence intervals (CIs), heterogeneity among studies was evaluated utilizing I2 statistic (Chi-Square test), and data were pooled using random effects meta-analyses. Results Meta-analysis of data from a total of 26 RCTs (n = 1891) indicated that probiotics significantly improved gut barrier function measured by levels of TER (MD, 5.27, 95% CI, 3.82 to 6.72, P < 0.00001), serum zonulin (SMD, -1.58, 95% CI, -2.49 to -0.66, P = 0.0007), endotoxin (SMD, -3.20, 95% CI, -5.41 to -0.98, P = 0.005), and LPS (SMD, -0.47, 95% CI, -0.85 to -0.09, P = 0.02). Furthermore, probiotic groups demonstrated better efficacy over control groups in reducing inflammatory factors, including CRP, TNF-α, and IL-6. Probiotics can also modulate the gut microbiota structure by boosting the enrichment of Bifidobacterium and Lactobacillus. Conclusion The present work revealed that probiotics could improve intestinal barrier function, and alleviate inflammation and microbial dysbiosis. Further high-quality RCTs are warranted to achieve a more definitive conclusion.

Abstract
Abstract
Background
A new classification of type 1 and 2 myocardial infarction (MI) derived from the fourth universal definition of MI (UDMI) has been recently proposed, based on pathophysiology of coronary artery disease (CAD),. We assessed the impact of this new MI categorization on epidemiology and outcomes.
Methods
Retrospective study including all consecutive patients hospitalized for an acute MI in a multicenter database (RICO). MI was defined according to current UDMI. Rates and outcomes of T1MI and T2MI were addressed according to the new classification.
Results
Among the 4573 patients included on our study, 3710 patients (81.1%) were initially diagnosed with T1M1 and 863 (18.9%) with T2MI. After reclassification, 96 T2MI patients were moved into the T1MI category. Out of the remaining 767 patients with T2MI, 567 underwent coronary angiography, and were adjudicated as type 2A MI (68.6%) with obstructive CAD, and type 2B MI (31.4%) without obstructive CAD.
When compared with T1MI and T2BMI, T2AMI patients had worse in-hospital outcomes, including heart failure (p<0.001), recurrent infarction (p<0.048) and mechanical complications such as mitral insufficiency (p=0.001). The 3 groups (T1AMI, T2AMI and T2BMI) had similar all-cause and cardiovascular death rates, with a trend for a higher all-cause mortality in T2AMI patients.
Kaplan-Meier one-year survival curves showed higher all-cause and cardiovascular causes mortality in T2AMI patients compared to T1MI and T2BMI (p<0.001). In multivariate Cox regression, type of MI was independent predictor of death.
Conclusion
Our large observational multicenter study shows major disparities in mortality according to type of MI and support the relevance of the new MI classification to improve risk classification. Our findings may will help identifying specific phenotypes and considering personalized diagnostic and management strategies.

Abstract
Obesity-prone (OP) individuals have a significant predisposition to obesity and diabetes. Previously, we have found that OP individuals, despite being normal in weight and BMI, have already exhibited diabetes-related DNA methylation signatures. However, the underlying mechanisms remain obscure. Here we determined the effects of gut microbiota on DNA methylation and investigated the underlying mechanism from microbial-derived short-chain fatty acids (SCFAs). Diabetes-related DNA methylation loci were screened and validated in a new OP cohort. Moreover, the OP group was revealed to have distinct gut microbiota compositions, and fecal microbiota transplantation (FMT) demonstrated the role of gut microbiota in inducing diabetes-related DNA methylations and glucolipid disorders. UPLC-ESI-MS/MS analysis indicated a significantly lower level of total fecal SCFAs in the OP group. The gut microbiota from OP subjects yielded markedly decreased total SCFAs, while notably enriched propionate. Additionally, propionate was also identified by variable importance in projection (VIP) score as the most symbolic SCFAs of the OP group. Further cellular experiments verified that propionate could induce hypermethylation at locus cg26345888 and subsequently inhibit the expression of the target gene DAB1, which was crucially associated with clinical vitamin D deficiency and thus may affect the development and progression of diabetes. In conclusion, our study revealed that gut microbiota-derived propionate induces specific DNA methylation, thus predisposing OP individuals to diabetes. The findings partially illuminate the mechanisms of diabetes susceptibility in OP populations, implying gut microbiota and SCFAs may serve as promising targets both for clinical treatment and medication development of diabetes.

Abstract
We reported that in a 29-year-old male patient with hyperthyroidism, bilateral breast swelling appeared in three days after starting methimazole and gradually aggravated. Several days later, a small amount of transparent liquid could be squeezed out from bilateral mammary glands. Breast ultrasound confirmed gynaecomastia. The level of testosterone, estradiol and luteinizing hormone increased. After the patient continued taking methimazole for a while, gynaecomastia relieved. Testosterone, luteinizing hormone and thyroid functions restored to normal. The possible mechanisms included increased levels of serum total cholesterol and relatively decreased T3 after initiating methimazole.

Abstract
BACKGROUND To assess the evolution of the epidemiology and management of patients hospitalized to Abidjan Heart Institute for acute coronary syndrome (ACS). METHODS Cross-sectional study comparing two periods: from January 2002 to December 2009 (period 1) and from January 2010 to December 2016 (period 2), including all patients aged 18 years old, admitted to Intensive Care Unit of Abidjan Heart Institute for ACS. RESULTS One thousand eleven (1011) patients were included among the 6784 patients admitted to Intensive Care Unit of Abidjan Heart Institute for a cardiovascular disease. The overall prevalence of ACS was 14.9%. The prevalence in period 2 was significantly higher than in period 1 (22.6% and 7.3% respectively, p < 0.001). Diabetes (33.5%, p < 0.001) significantly, and smoking (30.7%, p = 0.30) had the largest rises from period 1 to period 2. ST-segment Elevation Myocardial Infarction was the main clinical presentation during both periods. The median time to treatment (p = 0.46) and length of hospital stay (p <0.001) decreased during period 2. Percutaneous coronary intervention (PCI) was performed in 173 patients (22.6%) during the period 2 and 42 patients (5.5%) underwent primary PCI. The rate of fibrinolysis increased significantly between the two periods (9.5%, p <0.001). In-hospital death increased during period 2 (10.4%, p = 0.07). CONCLUSION The burden of ACS and its related mortality have risen alarmingly past years in Côte d'Ivoire. Healthcare policies should help improve the management and outcomes of patients.

Abstract
Objective: To investigate the relationship between body mass index (BMI) and sexual development in Chinese children. Methods: A nationwide multicenter and population-based large cross-sectional study was conducted in 13 provinces, autonomous regions and municipalities of China from January 2017 to December 2018. Data on sex, age, height, weight were collected, BMI was calculated and sexual characteristics were analyzed. The subjects were divided into four groups based on age, including ages 3-<6 years, 6-<10 years, 10-<15 years and 15-<18 years. Multiple Logistic regression models were used for evaluating the associations of BMI with sexual development in children. Dichotomous Logistic regression was used to compare the differences in the distribution of early and non-early puberty among normal weight, overweight and obese groups. Curves were drawn to analyze the relationship between the percentage of early puberty and BMI distribution in girls and boys at different Tanner stages. Results: A total of 208 179 healthy children (96 471 girls and 111 708 boys) were enrolled in this study. The OR values of B2, B3 and B4+ in overweight girls were 1.72 (95%CI: 1.56-1.89), 3.19 (95%CI: 2.86-3.57), 7.14 (95%CI: 6.33-8.05) and in obese girls were 2.05 (95%CI: 1.88-2.24), 4.98 (95%CI: 4.49-5.53), 11.21 (95%CI: 9.98-12.59), respectively; while the OR values of G2, G3, G4+ in overweight boys were 1.27 (95%CI: 1.17-1.38), 1.52 (95%CI: 1.36-1.70), 1.88 (95%CI: 1.66-2.14) and in obese boys were 1.27 (95%CI: 1.17-1.37), 1.59 (95%CI: 1.43-1.78), and 1.93 (95%CI: 1.70-2.18) (compared with normal weight Tanner 1 group,all P<0.01). Analysis in different age groups found that OR values of obese girls at B2 stage and boys at G2 stage were 2.02 (95%CI: 1.06-3.86) and 2.32 (95%CI:1.05-5.12) in preschool children aged 3-<6 years, respectively (both P<0.05). And in the age group of 6-10 years, overweight girls had a 5.45-fold risk and obese girls had a 12.54-fold risk of B3 stage compared to girls with normal BMI. Compared with normal weight children, the risk of early puberty was 2.67 times higher in overweight girls, 3.63 times higher in obese girls, and 1.22 times higher in overweight boys, 1.35 times higher in obese boys (all P<0.01). Among the children at each Tanner stages, the percentage of early puberty increased with the increase of BMI, from 5.7% (80/1 397), 16.1% (48/299), 13.8% (27/195) to 25.7% (198/769), 65.1% (209/321), 65.4% (157/240) in girls aged 8-<9, 10-<11 and 11-<12 years, and 6.6% (34/513), 18.7% (51/273), 21.6% (57/264) to 13.3% (96/722), 46.4% (140/302), 47.5% (105/221) in boys aged 9-<10, 12-<13 and 13-<14 years, respectively. Conclusions: BMI is positively correlated with sexual development in both Chinese boys and girls, and the correlation is stronger in girls. Obesity is a risk factor for precocious puberty in preschool children aged 3-<6 years, and 6-<10 years of age is a high risk period for early development in obese girls.

Abstract
hine Muscat, with its excellent quality and unique Muscat aroma, is emerging as one of the most profitable table grape cultivars in Asia. However, in-depth analysis of the cultivar’s aroma profile before berries are harvest-ready is lacking. The aroma components and their concentrations undergo substantial changes during berry ripening, which provides an opportunity for producing some juice/wine products with special flavour. In this study, the evolution of free and bound aroma compounds in Shine Muscat grapes was analysed from EL-35 to EL-38. The main aroma attributes of harvest-ready berries were: ‘green’, ‘sweet’, ‘floral’ and ‘fruity’. The headspace SPME-GC-MS analysis revealed that alcohols were the most abundant free and bound compounds in Shine Muscat. Furthermore, the free forms of hexanal, β-damascenone, and (E, Z)-2,6-nonadienal determined the aroma characteristics of the grapes directly, while the bound forms of β-damascenone, (E, Z)-2,6-nonadienal, and 2-hexanol determined the aroma of Shine Muscat that cannot to be smelled directly. Taking all indicators together, we believe that picking Shine Muscat grapes at EL-37 (when a minimum TSS of 17% has been reached) maintains its fine aroma characteristics. These results lay the foundation for the further development, utilisation and study of the aroma characteristics of Shine Muscat grapes.

Abstract
Accumulating knowledge has been achieved on DNA methylation participating in numerous cellular processes and multiple human diseases; however, few studies have addressed the pleiotropic role of DNA methylation in Chinese herbal medicine (CHM). CHM has been used worldwide for the prevention and treatment of multiple diseases. Newly developed epigenetic techniques have brought great opportunities for the development of CHM. In this review, we summarize the DNA methylation studies and portray the pleiotropic role of DNA methylation in CHM. DNA methylation serves as a mediator participating in plant responses to environmental factors, and thus affecting CHM medicinal plants growth and bioactive compound biosynthesis which are vital for therapeutic effects. Furthermore, DNA methylation helps to uncover the pharmaceutical mechanisms of CHM formulae, herbs, and herbal-derived compounds. It also provides scientific validation for constitution theory and other essential issues of CHM. This newly developed field of DNA methylation is up-and-coming to address many complicated scientific questions of CHM; it thus not only promotes disease treatment but also facilitates health maintenance.

Abstract
Oplopanax elatus (Nakai) Nakai, in the Araliaceae family, has been used in traditional Chinese medicine (TCM) to treat diseases as an adaptogen for thousands of years. This study established an ultra-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF/MS) method to identify chemical components and biotransformation metabolites of root bark extract from O. elatus. A total of 18 compounds were characterized in O. elatus extract, and 62 metabolites by human intestinal microbiota were detected. Two polyynes, falcarindiol and oplopandiol were recognized as the main components of O. elatus, whose metabolites are further illustrated. Several metabolic pathways were proposed to generate the detected metabolites, including methylation, hydrogenation, demethylation, dehydroxylation, and hydroxylation. These findings indicated that intestinal microbiota might play an essential role in mediating the bioactivity of O. elatus.

Abstract
Abstract
Background
Atrial fibrillation (AF) and heart failure (HF) often coexist and are closely intertwined, each condition worsening the other. The temporal relationships between these two disorders have not yet been fully explored. We assessed, on a nationwide scale, the prognosis of patients hospitalized with HF and AF, based on the timing of AF and HF development.
Methods
From the administrative database covering hospital care for the whole French population, we identified 1,349,638 patients diagnosed with both AF and HF between 2010 and 2018: 956,086 of these AF patients developed HF first (prevalent HF) and 393,552 developed HF after AF (incident HF). The outcome analysis (all-cause death, cardiovascular [CV] death, ischemic stroke or hospitalization for HF) was performed with follow-up starting at the time of last event between AF or HF in the whole cohort and in 427,848 propensity-score-matched patients (213,924 with incident HF and 213,924 with prevalent HF).
Results
During follow-up (mean follow-up 1.6±1.9 year), matched patients with prevalent HF had a higher risk of all-cause death (21.6 vs 19.2%/year), CV death (7.6 vs 6.5%/year) as well as non-cardiovascular death (13.9 vs 12.7%/year) than those with incident HF. The risk for ischemic stroke was lower in the prevalent HF group (1.2 vs 2.4%/year).
Conclusion
In patients hospitalized with both AF and HF, we identified two distinct clinical entities based on the chronological sequence of the two disorders. Patients in whom HF preceded AF (prevalent HF) had higher mortality and higher risk of rehospitalization for HF.

Abstract
Objective We report in this work the efficacy of highly active antiretrovirals (ARVs) alone in the treatment of diffuse infiltrative lymphocytosis syndrome (DILS) without the use of corticosteroids, which appears risky in patients living with HIV. Observation This is a 60-year-old HIV-positive patient, discovered during the etiological workup of renal failure, which revealed a non-nephrotic glomerular profile. The renal biopsy found an interstitial infiltrate of CD8 suggestive of DILS. Management consisted in starting ARV treatment alone (lamuvidine, abacavir and raltegravir) without associated corticosteroid therapy. The clinical evolution under treatment was marked by a recovery of the renal function with a creatininemia at 99 μmol/l, a regression of the proteinuria, a CD4 rate at 293/mm3 and an HIV viral load at 533.3 copies or 1.6 log in the space of 3 months. Conclusion DILS is a diffuse systemic disease in HIV patients who are usually under poor virological control. In view of the strong immunosuppression and the absence of other infiltrative diseases, it appeared to us to be risky and unjustified to add a corticosteroid therapy.

Abstract
Abstract
Study question
Does follicular extracellular vesicles of women with polycystic ovarian syndrome (PCOS-EVs) interfere with the quality of oocytes?
Summary answer
PCOS-EVs induced oxidative stress in the oocytes and inhibited oocyte maturation by increasing the abnormal mitochondria distribution and abnormal spindle rates.
What is known already
Polycystic ovarian syndrome (PCOS) is a common endocrine disorder in women of reproductive age, with a prevalence up to 10%. Women with PCOS are characterized by a clustering of features, including hyperandrogenism, polycystic ovarian morphology, and notably, anovulation. Although international guidelines recommend assisted reproduction techniques to be an effective resort for PCOS patients to conceive. However, even after overcoming ovulatory dysfunction via ovulation induction, the pregnancy outcomes of patients with PCOS were far from satisfying with lower fertilization, cleavage, and implantation rates, implicating that theoocyte quality of these patients are affected. Whereas the mechanisms have not been elucidated yet.
Study design, size, duration
Follicular fluid of PCOS patients (n = 10) and healthy controls (n = 10) were collected and used for extracellular vesicles (EVs) isolation via ultracentrifugation. Germinal vesicle (GV) oocytes collected from female ICR mice were cocultured with RIF-EVs or FER-EVs, respectively, and PBS served as a blank control. GV breakdown (GVBD) rate and maturation rate were calculated at two-hour and fourteen-hour of co-culture, respectively. Besides, oocyte mitochondria distribution, meiosis spindle morphology, and oxidative status were assessed in different groups.
Participants/materials, setting, methods
EVs were determined by western blotting, nanoparticle tracking analysis, and transmission electron microscopy. Fluorescence labeled EVs were used to visualize internalization by oocytes. Oocytes mitochondria and mitosis spindles were stained with fluorescence, and abnormal mitochondria rate or abnormal spindle rate was calculated. Reactive oxygen species (ROS) level was detected in the differently treated oocytes. Moreover, the expression of CAT, GSS, and SOD was determined in the oocytes using quantitative reverse transcription polymerase chain reaction.
Main results and the role of chance
Both PCOS-EVs and CTRL-EVs are bilayered vesicles, ranging from 100 to 150 nm, and enriched in Alix, TSG101, and CD9. EVs could be internalized by oocytes within one hour. After coculture, the GVBD rate was similar among the three groups; whereas the maturation rate was significantly decreased in the PCOS-EV group compared with CTRL-EV group or PBS group. In addition, the abnormal mitochondria distribution rate or abnormal spindle rate were significantly increased in the PCOS-EV group compared with PBS or CTRL-EV group. The ROS level was increased in the PCOS-EV group compared with CTRL-EV group, and the expression of CAT, GSS, and SOD was increased in the PCOS-EV-treated oocytes.
Limitations, reasons for caution
Our study did not identify the contents of PCOS-EVs and CTRL-EVs, and the molecular mechanisms of dysregulations induced by PCOS-EVs need further researches to investigate.
Wider implications of the findings: This work confirmed that EV-conducted cellular communication played an important role in oocyte development in women with PCOS. The dysregulation of oocytes induced by PCOS-EVs might be related to the poor oocyte quality of women with PCOS, which may provide a novel target to improve pregnancy outcomes of these patients.

Abstract
The gut microbiota exists throughout the full life cycle of the human body, and it has been proven to have extensive impacts on health and disease. Accumulating evidence demonstrates that the interplay between gut microbiota and host epigenetics plays a multifaceted role in health maintenance and disease prevention. Intestinal microflora, along with their metabolites, could regulate multiple epigenetic pathways; e.g., DNA methylation, miRNA, or histone modification. Moreover, epigenetic factors can serve as mediators to coordinate gut microbiota within the host. Aiming to dissect this interplay mechanism, the present review summarizes the research profile of gut microbiota and epigenetics in detail, and further interprets the biofunctions of this interplay, especially the regulation of intestinal inflammation, the improvement of metabolic disturbances, and the inhibition of colitis events. This review provides new insights into the interplay of epigenetics and gut microbiota, and attempts to reveal the mysteries of health maintenance and disease prevention from this new perspective.

Abstract
This investigation studied the effect of concentrated growth factor and nanofat on aging skin of nude mice induced by D-galactose. BALB/c mice were randomly divided into five groups: 5 mice in the control group were fed normally without any intervention, 9 mice were treated with concentrated growth factor (CGF), 9 mice were treated with nanofat (NF), 9 mice were treated with CGF+NF, and 9 mice in the model group (no treatment after subcutaneous injection of D-galactose). Relevant indicators are measured and recorded. In skin and serum, SOD and GSH content in the model group were significantly lower than those in other groups (P<0.05), and the MDA of the three treatment groups was significantly lower than that of the model group (P<0.05). Compared with the control group, the contents of total collagen, type I collagen and type III collagen in the NF group and model group were decreased in different degrees (P<0.05); the contents of elastin and elastic fiber in the skin of nude mice in the model group and NF group were significantly decreased. Compared with the model group, he number of CD31 and VEGF in the treatment group was significantly increased (P<0.01); the skin AGE content of three treatment groups was significantly lower (P<0.05). These findings suggest that concentrated growth factor and nanofat may have a significant effect on delaying aging skin induced by D-galactose in nude mice.

Abstract
With the rapid development of industrialization and urbanization in China, energy and vehicle consumption have continued to increase in recent years and air pollution has become serious. In early 2020, Corona Virus Disease 2019 broke out in Wuhan, China. From January 29, 2020, several sources of the air pollution almost all stopped working, including gasoline burning vehicles, dust producing building sites, coal-fired factories, etc. Five indicators of the atmospheric environmental quality were observed from December 19, 2019 to April 30, 2020 in nine cities and 1-h average concentrations, 24-h average concentrations and Air Quality Index were assessed. The 1-h average concentrations of the nitrogen dioxide, the ozone and the sulfur dioxide showed obvious difference though the closure did not change the sequence of the five pollutants' concentrations in the air at diverse sampling moments. The changing of the 24-h average concentrations of the five pollutants indicated the amount of pollutants in the air were greatly affected by human activities. The nitrogen dioxide, the sulfur dioxide and the particulate matters decreased obviously in the closure. The air in the metropolis and the south-east cities were relatively clean and the pollutants' concentrations decreased slightly during the closure period. The northern and the heavy industrial cities showed significant drop on air pollution indicators and the air quality of the two city groups could be greatly improved if some effective measures could be taken of environmental management and regional development.

Abstract
OBJECTIVE To explore the regulatory mechanism of lncRNA NORAD on proliferation and invasion of ovarian cancer cells through miR-199a-3p. PATIENTS AND METHODS Eighty-six ovarian cancer tissues and 86 tissues adjacent to cancer, human ovarian cancer cell lines SKOV3, HO-8910, A2780, OVCAR-3, and human normal ovarian epithelial cell line IOSE80 were collected. MiR-199a-3p-mimics, miR-199a-3p-inhibitor, miR-NC, si-NORAD, Sh-NORAD, and NC were transfected into HO-8910 and A2780 cells, the expression levels of lncRNA NORAD and miR-199a-3p in ovarian cancer tissues and cells were detected by qRT-PCR, and the expression levels of N-cadherin, E-cadherin, and vimentin in cells were detected by WB. Cell Counting Kit-8 (CCK-8), transwell, and cell scratch tests were used to detect proliferation, invasion, and migration of cells, and the relationship between lncRNA NORAD and miR-199a-3p was confirmed by the Dual-Luciferase reporter assay. RESULTS LncRNA NORAD was highly expressed and miR-199a-3p was lowly expressed in ovarian cancer, and the expression levels of LNCRNARAD and miR-199a-3p were negatively correlated. Cell experiments showed that inhibiting the expression of lncRNA NORAD or up-regulating the expression of miR-199a-3p could inhibit the proliferation, invasion, migration, and EMT of ovarian cancer cells, while up-regulating the expression of lncRNA NORAD or inhibiting the expression of miR-199a-3p could promote their proliferation, invasion, migration, and EMT. Dual-Luciferase reporter assay confirmed that there was a regulatory relationship between lncRNA NORAD and miR-199a-3p. CONCLUSIONS LncRNA NORAD was highly expressed in ovarian cancer tissues, while silencing lncRNA NORAD expression could inhibit the proliferation, invasion, migration, and EMT of ovarian cancer cells by regulating miR-199a-3p, which might be a new target for the diagnosis and treatment of ovarian cancer.

Abstract
Objective: To observe the efficacy and safety of sirolimus combined with calcineurin inhibitor (CNI) in the treatment of glucocorticoid resistant/dependent extensive chronic graft-versus-host disease (cGVHD) . Methods: A total of 27 patients with steroid-resistant/steroid-dependent extensive cGVHD from November 2015 to January 2019 were enrolled and given sirolimus capsules combined with cyclosporine or tacrolimus to observe the clinical efficacy and adverse events. Results: The median duration of medication was 14.2 months and the mean duration was 16.7 months. The median follow-up time was 20.1 months (12.9-46.1 months) . Following the 6-month follow-up, 3 cases achieved complete response (CR) and 12 cases partial response (PR) . The overall response rate (ORR) was 55.6% ; for progression-free survival (PFS) , PFS-6 reached 88.9% (24/27) , and for overall survival (OS) , OS-6 was 100% . At the 1-year follow-up, there were 5 cases of CR and 11 cases of PR, ORR was 59.3% , PFS-12 reached 62.9% (17/27) , and OS-12 was 100% . The subgroup analysis found that the program was more effective for cGVHD in male donors and the target organ analysis had an advantage in the treatment of oral cavity, skin, and liver rejection. Adverse events were observed: hyperlipidemia 11.1% , oral ulcer 7.4% , fungal infection 11.1% , liver injury 3.7% , renal insufficiency 0, and no new CMV and EB viremia. Conclusion: Sirolimus combined with calcineurin inhibitors is effective in treating steroid-resistant/steroid-dependent extensive cGVHD, especially because adverse reactions (renal toxicity, CMV, EBV infection) are low in number, which is suitable for long-term treatment of cGVHD.

Abstract
Abstract
Background
Although patients with familial heterozygous hypercholesterolemia (FH) are at high risk of early myocardial infarction (MI), coronary artery disease (CAD) burden of FH patients with acute MI remains to be investigated.
Methods
All consecutive patients hospitalized for an acute MI in a multicenter database (RICO) from 2012–2017 who underwent coronary angiography were considered. FH (n=86) was diagnosed using Dutch Lipid Clinic Network criteria (score ≥6). The angiographic features of FH patients were compared with patients without FH (score 0–2) (n=166), after matching for age, sex and diabetes (1:2).
Results
When compared with patients without FH, patients with FH had higher prevalence of personal and familial history of CAD (17 vs 5%, and 74 vs 5%, p=0.002 and p<0.001, respectively), and hypertension (54 vs 36%, p=0.006). Chronic statin treatment was used in only 45% of FH patients. At coronary angiography, FH had increased extent of CAD (SYNTAX score 11 (4–21) vs 8 (3–16), p=0.049) and multivessel disease (58% vs 43%, p=0.021). Significant stenosis was more frequent in left and right marginal coronary arteries. FH patients showed a trend toward more complex lesions, with less thrombus (28 vs 39%, p=0.076), but a 2 times higher rate of bifurcation lesions and calcifications (23 vs 12% and 20 vs 10%, p=0.021 and p=0.036).
Conclusions
This study addressing the coronary lesions features of FH patients with acute MI shows that FH patients had more severe CAD burden, and were characterized by complex anatomy features.

Abstract
Abstract
Background
High level of Lipoprotein(a), Lp(a), is a well-recognised independent risk factor for atherosclerotic cardiovascular disease (ASCVD). However, limited data are available on the prevalence of high Lp(a) levels and on the threshold associated to coronary artery disease (CAD) burden in patients with acute myocardial infarction (MI).
Methods
We aim at assessing CAD burden in 651 consecutive patients hospitalized for an acute MI from January 2019 to September 2019 who underwent coronary angiography. Patients characteristics and angiographic features were compared for patients with Lp(a) <50 mg/dL (normal), ≥50 mg/dL (high) and >80 mg/dL (i.e >90th percentile) (very high).
Results
The prevalence of Lp(a) ≥50 mg/dL was elevated (19.0%) and 65 patients (10.0%) were in the >90th percentile. Median (IQR) age was similar across the 3 groups (normal: 68 (59–79)y; high: 74 (63–80)y; very high: 71 (57–82)y, p=0.239). When compared with patients with normal Lp(a), patients with very high levels (≥80 mg/dL) had higher prevalence of personal history of ASCVD (29 vs 16%, p=0.021) and family history of CAD (37 vs 19%, p=0.005), and were more frequently women (43 vs 29%, p=0.009). At coronary angiography, patients with very high Lp(a) levels had increased extent of CAD (Median SYNTAX score 17 (5–25) vs 10 (5–17), p=0.002) and more frequent multivessel disease (69 vs 54%, p=0.02).
Conclusion
Among real world patients hospitalized for an acute MI, Lp(a) levels >80 mg/dL are associated with an increased CAD burden and this threshold identifies a subset of patients with features of high ASCVD risk.

Abstract
BACKGROUND Coronary artery disease is mainly due to atherosclerosis. The aim of this study was to evaluate the frequency of peripheral arterial disease in proven coronary artery disease and to determine the associated factors in our context. MATERIAL AND METHODS We included in a cross-sectional descriptive and analytical study 224 patients with proven coronary artery disease confirmed on coronary angiography from March 1 to October 30, 2019. It took place in the external exploration department of the Abidjan Heart Institute. An ultrasonographic exploration of the supra-aortic trunks and arteries of the lower extremity with measurement of the ankle brachial index (ABI) was carried out. RESULTS The mean age was 57.4±10.9 years (27-81years). There was a clear male predominance with a sex-ratio of 5. The prevalence of carotid artery disease was 56.4% of patients. The main factors associated with elevated Intima Media Thickness (IMT) and the presence of carotid plaques were male sex (OR=8.8; P=0.038), smoking (OR=2.5; P=0.049) and multi-truncular involvement (OR=3.2; P=0.014). In the lower extremities, there was a prevalence of peripheral arterial disease of 48.5%. The main factors associated with the decrease of ABI were age ≥50 years (OR=2.6; P=0.043), diabetes (OR=2.8; P=0.02), dyslipidemia (OR=3.8; P=0.001) and pluri-truncular involvement (OR=4.5; P<0.0001). CONCLUSION The presence of significant coronary artery disease in our context is associated with a high prevalence of peripheral carotid artery and lower extremity artery disease. This is all the more so as we are male, over 50 years old, pluri-truncular with many cardiovascular risk factors.

Abstract
Rheumatic mitral stenosis is still common in sub-Saharan Africa. The aim of this study was to evaluate the clinical and echocardiographic contraindications to the realization of percutaneous mitral commissurotomy (PMC) in Abidjan Heart Institute. We conducted a prospective, transversal and analytical study in the Exploration Unit from March 30, 2017 to March 30, 2018. Mitral stenosis was severe with an average anatomical surface area of 0.87cm2, an average gradient of 13.7 mmHg and an upstream repercussion (dilatation of the left atrium (78 ml/m2); moderate dilatation of the right atrium (22.3 cm2) and average pulmonary arterial hypertension (PAH) of 55 mmHg). The main clinical contraindications were a history of rest dyspnoea at 66.7%, permanent atrial fibrillation at 53.3 % and clinical manifestations of severe PAH in 40 %. Unfavourable anatomy (95.7 %) evaluated by scores of Wilkins, Cormier and especially Echoscore revisited; bicommissural fusion (95.7 %) and severe aortic valvulopathy (31.1%) were the main barriers in transthoracic echocardiography. In multivariate analysis after linear regression, valvular anatomy, as assessed by the various scores, was significantly related to low socioeconomic status (p=0.018), level of education (p=0.04), severity of mitral stenosis evaluated by the mean gradient (p=0.033) and the impact on the left atrium (p=0.015). Mitral stenosis presents several clinical and echocardiographic contraindications. Adverse anatomy is the main obstacle and is related to low socio-economic status, educational level and severity of stenosis.
