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
In deep tissue, optogenetics faces limitations with visible light. Here, we present a protocol for near-infrared (NIR) optogenetics manipulation of neurons and motor behavior in Caenorhabditis elegans using emissive upconversion nanoparticles (UCNPs). We describe steps for synthesizing and modifying UCNPs. We then detail procedures for regulating neurons using these UCNPs in the model organism C. elegans. Using NIR light allows for superior tissue penetration to manipulate neuronal activities and locomotion behavior. For complete details on the use and execution of this protocol, please refer to Guo et al.,1 Ao et al.,2 and Zhang et al.3.

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 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
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
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
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.

MEDECINE TROPICALE ET SANTE INTERNATIONALE 2021; 1:mtsibulletin.2021.118.

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.
