Granular materials such as sand, powders, and grains are omnipresent in daily life, industrial applications, and earth-science [1]. When unperturbed, they form stable structures that resemble the ones of other amorphous solids like metallic and colloidal glasses [2]. It is commonly conjectured that all these amorphous materials show a universal mechanical response when sheared slowly, i.e., to have an elastic regime, followed by yielding [3]. Here we use X-ray tomography to determine the microscopic dynamics of a cyclically sheared granular system in three dimensions. Independent of the shear amplitude $\Gamma$, the sample shows a cross-over from creep to diffusive dynamics, indicating that granular materials have no elastic response and always yield, in stark contrast to other glasses. The overlap function [4] reveals that at large $\Gamma$ yielding is a simple cross-over phenomenon, while for small $\Gamma$ it shows features of a first order transition with a critical point at $\Gamma\approx 0.1$ at which one finds a pronounced slowing down and dynamical heterogeneity. Our findings are directly related to the surface roughness of granular particles which induces a micro-corrugation to the potential energy landscape, thus creating relaxation channels that are absent in simple glasses. These processes must be understood for reaching an understanding of the complex relaxation dynamics of granular systems.

This paper presents Segregator, a global point cloud registration framework that exploits both semantic information and geometric distribution to efficiently build up outlier-robust correspondences and search for inliers. Current state-of-the-art algorithms rely on point features to set up putative correspondences and refine them by employing pair-wise distance consistency checks. However, such a scheme suffers from degenerate cases, where the descriptive capability of local point features downgrades, and unconstrained cases, where length-preserving (l-TRIMs)-based checks cannot sufficiently constrain whether the current observation is consistent with others, resulting in a complexified NP-complete problem to solve. To tackle these problems, on the one hand, we propose a novel degeneracy-robust and efficient corresponding procedure consisting of both instance-level semantic clusters and geometric-level point features. On the other hand, Gaussian distribution-based translation and rotation invariant measurements (G-TRIMs) are proposed to conduct the consistency check and further constrain the problem size. We validated our proposed algorithm on extensive real-world data-based experiments. The code is available: https://github.com/Pamphlett/Segregator., Comment: 6 pages, 5 figures. Accepted to ICRA2023

This article addresses the ethical issues of respect for autonomy and informed consent, focusing on how clinicians should deal with these concepts in clinical practice. We first clarify the concept of respect for autonomy and its practical application, as well as informed consent. We then track the origin and development of informed consent both in western countries and in China. Followed by describing several challenges that limit the practice of informed consent, we make our suggestions so as to help clinicians handle the informed consent in daily practice.

In 2020 and 2021, great progress was made in the field of rare diseases in China. In the aspect of rare disease related policies, China built the National Key Laboratory of Rare Diseases and prepared for the National Quality Control Center of Rare Diseases. China has granted zero tariffs on raw materials and drugs for rare diseases since 2021, and the number of rare diseases included in health insurance in local areas has increased. In the aspect of drugs for rare disease, during the past two years, 14 drugs for rare diseases were included in the system of national health insurance; 13 were approved by China National Medical Products Administration; and more gained the qualification for prior review. In the aspect of patient registration and epidemiological study of rare diseases, China enabled the National Rare Diseases Registry System and set up the registry regime. The first epidemiological study of myasthenia gravis in China was published. The screening programof lysosomal storage syndrome and the first cohort study on achondroplasia in China were started. Besides the official policies and channels, organizations and informational platforms for patients also played an important role in the field of rare diseases.

Aims: The CYP2D6*41 variant is the second or third frequent reduced function allele in Chinese with a frequency of around 3–4%, while it is the major reduced function allele in Indians, Saudi Arabians and Caucasians with frequencies of around 10–20%. The present study was designed to explore the impact of CYP2D6*41 on the metabolic activity of CYP2D6 using phenotyping methods in urine, plasma, and saliva.Methods: We used dextromethorphan as the probe drug to analyze the phenotypes of 87 subjects with CYP2D6*1/*1 (n = 22), CYP2D6*1/*2 (n = 33), CYP2D6*2/*2 (n = 4), CYP2D6*1/*41 (n = 5), CYP2D6*2/*41 (n = 3), CYP2D6*10/*41 (n = 16), and CYP2D6*5/*41 (n = 4) for CYP2D6. The ratio of parent drug to metabolite in 3 h saliva, 3 h plasma, and in 0–3 h urine was considered the metabolic ratio (MR).Results: The CYP2D6*41 allele had substantial impact on the metabolic activity of CYP2D6 regardless of the urinary, plasma, or salivary phenotyping method used. In subjects with CYP2D6*1(or *2)/*1(or *2), *1 (or *2)/*41, *10/*41 and *5/*41 (all p < 0.001), the salivary, plasma, or urinary MR value increased. The MRs in saliva, plasma, and urine displayed high correlations.Conclusion: The activity score system or the consensus activity score system, instead of the traditional phenotype classification, could predict the CYP2D6 enzyme activity more accurately. CYP2D6*41 had similar or more impact on the CYP2D6 enzyme activity as compared with CYP2D6*10. Assigning *41 a score of 0.5 and assigning *10 a score of 0.25 according to the consensus AS system should be reconsidered.

- Abstract
Additional file 1: Supplementary Figure 1. Overview of in-house data set and the ZetaSuite flowchart. a, In-house data format. Two-dimensional in-house data are generated from a siRNA screen to identify global splicing regulators. In each siRNA-treated well, 407 alternative splicing (AS) events are interrogated by RNA Annealing Selection Ligation sequencing (RASL-seq). A total number of 18,480 siRNA pools against annotated protein-coding genes in the human genome are arrayed in 57 384-well plates. Each plate also contains 6 negative controls (NS-mix), 5 positive controls (siPTBP1) and 5 killer controls (siNEK6). After screening, raw data are tabulated in a matrix as the log2 isoform ratio (exon included isoform/exon skipped isoform). b, Flowchart of the ZetaSuite software in three parts ( https://github.com/YajingHao/ZetaSuit e), as detailed in the text. Supplementary Figure 2. Data analysis using existing statistical approaches. a-b, Z-score distribution of all non-expressors (n=5006) based on 5 randomly selected AS events (a) or all interrogated AS events (b). Red-marked dots indicate hits with Z-score>=3, showing the majority (~80%, see Fig. 2c) of non-expressors scored as false-positive hits when all measured AS events are included in the analysis with the traditional Z-score-based approach. c-d, The Z-score rank distribution (from induced exon skipping on left to exon inclusion on right) of SF3B1 (c) and SRSF2 (d) responsive AS events among total detected AS events in the screen, showing skewing of SF3B1-induced splicing toward exon skipping and SRSF2-induced splicing in both directions. e, Summary of hit numbers at common FDR cutoffs using 4 different existing methods.

Weighted ζ-score in two directions calculated by ZetaSuite are combined in this analysis to reflect the overall functional consequence. This is not applicable to other software, and we thus display the data separately. Supplementary Figure 4.

Arrow indicates the chosen threshold and associated FDR. b, SS plots for five genome-wide RNAi screens, showing the calculated balance points in each (top panel 1 to 5). One dataset (panel 5) was permutated 5 times to illustrate the lack of a balance point if the data quality is compromised (bottom panel). c-d, Hits with related functions or due to off-target effects. Results of our secondary screen with 4 individual siRNAs in comparison with the pool of those siRNAs (left) or with the pools of other siRNAs against genes that show significant functional similarity (right, reflected by circle size). Hits are due to related functions when multiple single siRNAs produce similar results (c) or to off-target effects when a single siRNA is responsible for the similarity to both siRNA pools (d). e, Deduced SVM curves using two different sets of positive controls. SVM1 is defined with siPTBP1 repeats and SVM2 with a set of known spliceosome components listed in Supplementary Fig. 3a. f, Diagram to illustrate the calculation of weighed ζ-scores without using a SVM curve. g, Venn diagrams showing the overlaps of high confidence hits selected using different SVM curves (left) or with and without using a SVM curve (right). h, Impact of readout (AS event) size on the efficiency in recovering a set of reference hits.

Estimating the structure of directed acyclic graphs (DAGs) of features (variables) plays a vital role in revealing the latent data generation process and providing causal insights in various applications. Although there have been many studies on structure learning with various types of data, the structure learning on the dynamic graph has not been explored yet, and thus we study the learning problem of node feature generation mechanism on such ubiquitous dynamic graph data. In a dynamic graph, we propose to simultaneously estimate contemporaneous relationships and time-lagged interaction relationships between the node features. These two kinds of relationships form a DAG, which could effectively characterize the feature generation process in a concise way. To learn such a DAG, we cast the learning problem as a continuous score-based optimization problem, which consists of a differentiable score function to measure the validity of the learned DAGs and a smooth acyclicity constraint to ensure the acyclicity of the learned DAGs. These two components are translated into an unconstraint augmented Lagrangian objective which could be minimized by mature continuous optimization techniques. The resulting algorithm, named GraphNOTEARS, outperforms baselines on simulated data across a wide range of settings that may encounter in real-world applications. We also apply the proposed approach on two dynamic graphs constructed from the real-world Yelp dataset, demonstrating our method could learn the connections between node features, which conforms with the domain knowledge., Comment: Accepted by AAAI23

Article Subject - Abstract
Endometrial cancer is the 6th most common carcinoma as well as the 2nd most common malignancy worldwide in women. It is closely related to fat content, and dyslipidemia is among the most significant metabolic changes in this cancer. Therefore, further understanding of the regulation mechanism in lipid metabolism of endometrial cancer is conducive to the development of better therapeutic strategies and methods. Here, we systematically review the signaling pathways that regulate lipid metabolism in endometrial cancer and the research progress of drugs and targeted therapies that act on lipid metabolism by retrieving relevant articles. The underlying mechanism of occurrence and development of endometrial cancer is relatively clear and comprehensively reviewed here. But following more research studies will help to illuminate more specific regulatory roles of lipid metabolism in endometrial cancer and explore new possible mechanisms, prognostic and therapeutic targets, and subsequent drugs. Our review will provide a full view for the following investigation of lipid metabolism in endometrial cancer.

Background: Cardiac paragangliomas (CPGLs) are rare neuroendocrine tumors that are easily overlooked and difficult to diagnose. Detailed comprehensive data regarding CPGL diagnosis and outcome are lacking.Methods: We retrospectively analyzed a cohort of 27 CPGL patients. This cohort represents the largest such cohort reported to date.Results: The prevalence of trilogy symptoms (concurrent palpitations, hyperhidrosis, and headache) was frequent (9/27, 33.3%). Sensitivity of echocardiography and contrast-enhanced computed tomography for localization of CPGL were 81.8% and 87%, respectively. Octreotide scintigraphy showed 100% sensitivity for detecting GPCLs, while sensitivity of I131-metaiodoben-zylguanidine scintigraphy was only 32.9%. Multiple tumors were found in 29.6% of patients. Most CPGLs originated from the epicardium or root of the great vessels (92.9%) and were mostly supplied by the coronary arteries and their branches (95.7%). Twenty-four patients underwent surgical treatment. Although local invasion was present in 40.0% of patients, it did not affect long-term outcome. Mean follow-up was 6.9 ± 3.6 years. Biochemical remission was achieved in 85% of patients. The recurrence rate was 15%.Conclusions: Manifestations of CPGLs are non-specific and they can be difficult to detect on imaging examinations. Octreotide scintigraphy should be performed in patients with suspected paragangliomas to screen for multiple lesions. Surgical resection of CPGLs can achieve symptom relief and biochemical remission.

Permanent magnet demagnetization is one of the common faults of permanent magnet synchronous motor, which seriously threatens the safe and reliable operation of the motor and reduces the service life of the motor. Based on the principle of permanent magnet demagnetization, this paper analyzes the causes of irreversible permanent magnet demagnetization. It focuses on the following three aspects: permanent magnet material, processing technology innovation and magnetic material itself improvement, permanent magnet synchronous motor electromagnetic structure optimization design and finally, the operation environment and necessary preventive measures. Combined with the actual condition and parameters of the motor, a 2D finite element simulation model of the motor was established to verify the anti-demagnetization ability of the motor and the feasibility of finite element simulation.

Combining X-ray tomography with simultaneous shear force measurement, we investigate shear-induced granular avalanches using spherical particles with different surface roughness. We find that systems consisting of particles with large surface roughness display quasi-periodic avalanches interrupted by crackling-like small ones. In contrast, systems consisting of particles with small roughness display no detectable avalanches. The stress drop of quasi-periodic avalanche shows a linear relation with the correlation length of particle non-affine displacement, suggesting that roughness enhances inter-particle locking and hence particle-level dynamic correlation length. However, the nonaffine displacement is two orders of magnitude smaller than particle size, indicating that stress is mainly released on the length scale of roughness. The correlation length of non-affine displacements abruptly increases when a quasi-periodic avalanche occurs, suggesting that quasi-periodic avalanches can be interpreted as a spinodal nucleation event in a first-order phase transition., 22 pages, 7 figures

As the COVID-19 spreads around the world, individuals's concerns about its extensive social, economic and political impact have become increasingly prominent. Chinese overseas students are one of the most paramount bearers of the globalization of education, and one of the groups most affected by the COVID-19. The COVID-19 continues and learning does not stop. Online courses brings new opportunities and challenges to Chinese overseas students. It takes ZOOM, GOOGLE MEET, OTTER and other online softwares as the carrier, and has a slice of advantages. As an example, online teaching that is not restricted by location and convenient for recording courses has become a blowout development trend. On the contrary, some individuals are also "skeptical" about online teaching through computers, quiet a few platforms and APPs, and believe that the quality of traditional face-to-face teaching is more stable. In the research, 100 Chinese overseas students from the Faculty of Educational Studies of University Putra Malaysia were used as samples to investigate their attitudes towards online courses during the COVID-19 and evaluate current situation through the questionnaire.

The performance of the Hatch Cover Drive Assembly operated in space is quite important for aircrafts. However, it is hard to experimental studies in space. As an alternative, theoretical analysis and simulation are employed to predict their performances on the ground. Herein, a mathematical model of the drive assembly was first established and simulated in Matlab. The armature current and mechanical efficiency were analyzed with respect to the operating temperature and load torque. Furthermore, a test setup according to the model was built to verify the validity of the proposed mathematical model. As a result, the prediction results are consistent with the experimental results very well with a maximum error of 11.0% in the armature current and 11.6% in the mechanical efficiency. The mechanical efficiency achieves to be the maximum value in vacuum as the load torque of 3.5N·m. It has the best performance as working around the room temperature. The proposed model would be used to predict the performance of drive assembly working in space. Our findings would be helpful for the designing, manufacturing and selection of motors and reducers for spacecrafts usage in future.

- Abstract
The aim of this study was to evaluate the efficacy and safety of empirical anti-tuberculous therapy (ATT) in patients with massive pericardial effusion (MPE) of unknown etiology in China. In-hospital patients with MPE were assessed retrospectively. Based on thorough examination excluding neoplastic, autoimmune, and nontuberculous infectious diseases, patients who had no evidence of tuberculosis (TB) were treated with empirical ATT (Group A) or not treated with empirical ATT (Group C), whereas those who had evidence of TB were treated with standard ATT (Group B). Clinical outcomes and mitigation of MPE were compared among the three groups to identify the effectiveness of ATT. The survival free of composite endpoint was estimated using the Kaplan-Meier method. A total of 185 eligible patients were recruited: 77 in Group A, 80 in Group B and 28 in Group C. The average follow-up was 52.9 ± 30.7, 49.4 ± 29.7 and 51.8 ± 30.2 months for Groups A, B and C, respectively. The incidence of composite endpoint was 23.3%, 24.4% and 85.7% in Groups A, B and C, respectively (P < 0.0001). However, the clinical recovery rate was greater in Group B compared with Group A (P = 0.027). No significant difference in the safety profile of ATT was noted between Groups A and B. MPE did not spontaneously decrease in 85.7% of patients in Group C. Empirical ATT should be considered in MPE of unknown etiology in countries with a high burden of TB.

- Abstract
OBJECTIVES: Three hundred million people living with rare diseases worldwide are disproportionately deprived of in-time diagnosis and treatment compared with other patients. This review provides an overview of global policies that optimize development, licensing, pricing, and reimbursement of orphan drugs. METHODS: Pharmaceutical legislation and policies related to access and regulation of orphan drugs were examined from 194 World Health Organization member countries and 6 areas. Orphan drug policies (ODPs) were identified through internet search, emails to national pharmacovigilance centers, and systematic academic literature search. Texts from selected publications were extracted for content analysis. RESULTS: One hundred seventy-two drug regulation documents and 77 academic publications from 162 countries/areas were included. Ninety-two of 200 countries/areas (46.0%) had documentation on ODPs. Thirty-four subthemes from content analysis were categorized into 6 policy themes, namely, orphan drug designation, marketing authorization, safety and efficacy requirements, price regulation, incentives that encourage market availability, and incentives that encourage research and development. Countries/areas with ODPs were statistically wealthier (gross national income per capita = $10 875 vs $3950, P < .001). Country/area income was also positively correlated with the scope of the respective ODP (correlation coefficient = 0.57, P < .001). CONCLUSIONS: Globally, the number of countries with an ODP has grown rapidly since 2013. Nevertheless, disparities in geographical distribution and income levels affect the establishment of ODPs. Furthermore, identified policy gaps in price regulation, incentives that encourage market availability, and incentives that encourage research and development should be addressed to improve access to available and affordable orphan drugs.

Hereditary transthyretin amyloidosis (ATTR) is an autosomal dominant rare disease caused by heterozygous mutations in the TTR gene, which encodes depolymerized transthyretin deposited in several organs. An induced pluripotent stem cell (iPSC) line of ATTR was generated from peripheral blood mononuclear cells of a 28 years old male patient carrying the TTR mutation p.Phe53Val. We used non-integrated episomal vectors to achieve the reprogramming of PBMCs, and further proved pluripotency by expression of typical stemness surface markers, gene expression of pluripotency genes and the pathological evidence of teratoma forming three germ layers in vivo. This iPSC line is a useful cellular model for screening potential therapeutic targets and studying the pathogenic mechanism of disease.

Rationale: Oral treprostinil improves exercise capacity in patients with pulmonary arterial hypertension (PAH), but the effect on clinical outcomes was unknown.\ud \ud Objectives: To evaluate the effect of oral treprostinil compared with placebo on time to first adjudicated clinical worsening event in participants with PAH who recently began approved oral monotherapy.\ud \ud Methods: In this event-driven, double-blind study, we randomly allocated 690 participants (1:1 ratio) with PAH to receive placebo or oral treprostinil extended-release tablets three times daily. Eligible participants were using approved oral monotherapy for over 30 days before randomization and had a 6-minute-walk distance 150 m or greater. The primary endpoint was the time to first adjudicated clinical worsening event: death; hospitalization due to worsening PAH; initiation of inhaled or parenteral prostacyclin therapy; disease progression; or unsatisfactory long-term clinical response.\ud \ud Measurements and Main Results: Clinical worsening occurred in 26% of the oral treprostinil group compared with 36% of placebo participants (hazard ratio, 0.74; 95% confidence interval, 0.56–0.97; P = 0.028). Key measures of disease status, including functional class, Borg dyspnea score, and N-terminal pro–brain natriuretic peptide, all favored oral treprostinil treatment at Week 24 and beyond. A noninvasive risk stratification analysis demonstrated that oral treprostinil–assigned participants had a substantially higher mortality risk at baseline but achieved a lower risk profile from Study Weeks 12–60. The most common adverse events in the oral treprostinil group were headache, diarrhea, flushing, nausea, and vomiting.\ud \ud Conclusions: In participants with PAH, addition of oral treprostinil to approved oral monotherapy reduced the risk of clinical worsening.\ud \ud Clinical trial registered with www.clinicaltrials.gov (NCT01560624).

Supplemental Digital Content is available in the text, Background: Several updated meta-analyses comparing percutaneous coronary intervention (PCI) with coronary artery bypass grafting (CABG) for left main coronary artery disease (LM CAD) have been published recently. However, the risk of false-positive results could be high in conventional updated meta-analyses due to repetitive testing of accumulating data. Therefore, we compared these treatment approaches via trial sequential analysis (TSA). Methods: The MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases were searched for published randomized controlled trials (RCTs) or subgroups of RCTs comparing PCI and CABG in patients with LM CAD. The primary outcome was major cardiac and cerebrovascular adverse events (MACCE). TSA was used to confirm the conclusions derived from conventional meta-analysis. Results: Six RCTs with 4700 patients were included. PCI was associated with a greater risk of MACCE compared with CABG (pooled relative risk [RR] 1.21, 95% confidence interval [CI]: 1.05–1.40, P = .008). In addition, PCI resulted in a significantly higher risk of revascularization than CABG (pooled RR 1.61, 95% CI: 1.33–1.95, P 32 (pooled RR 1.41, 95% CI: 1.12–1.76, P = .003), which was confirmed by the TSA. There was no difference in patients with a SYNTAX score from 0 to 32. Conclusions: In patients with LM CAD, CABG may be better than PCI for reducing MACCE due to a reduced risk of revascularization. CABG remains the first choice for LM CAD patients with high anatomic complexity, while PCI could be an alternative for those with low-to-moderate anatomic complexity.

Introduction: We herein describe a patient with chronic disseminated intravascular coagulation (DIC) induced by a giant thrombus in the left atrium. A 63-year-old woman was admitted to our hospital for evaluation of extensive mucocutaneous hemorrhage, especially at the sites of venipuncture, on May 21, 2015. Considering her long history of rheumatic heart disease and atrial fibrillation and her mitral valve replacement performed several years previously, we strongly suspected that the bleeding was closely related to postoperative over-anticoagulation of warfarin. After careful investigation, we found that her coagulopathy was induced by the chronic DIC, which was in turn secondary to a left atrial giant thrombus. This is a rarely reported cause of chronic DIC. Cardiac computed tomography and echocardiography showed apparent biatrial enlargement; the morphology and function of the ventricles were unaffected. After anticoagulant therapy, the bleeding tendency and coagulation index were significantly improved. Conclusion: A left atrial thrombus should be considered as a differential diagnosis of chronic DIC, especially in patients with predisposing heart conditions. Because treatment of the underlying cause is paramount in the management of chronic DIC, this case is of great clinical value.

Mounting evidence supports that fine particulate matter adversely affects cardiometabolic diseases particularly in susceptible individuals; however, health effects induced by the extreme concentrations within megacities in Asia are not well described. We enrolled 65 nonsmoking adults with metabolic syndrome and insulin resistance in the Beijing metropolitan area into a panel study of 4 repeated visits across 4 seasons since 2012. Daily ambient fine particulate matter and personal black carbon levels ranged from 9.0 to 552.5 µg/m(3) and 0.2 to 24.5 µg/m(3), respectively, with extreme levels observed during January 2013. Cumulative fine particulate matter exposure windows across the prior 1 to 7 days were significantly associated with systolic blood pressure elevations ranging from 2.0 (95% confidence interval, 0.3-3.7) to 2.7 (0.6-4.8) mm Hg per SD increase (67.2 µg/m(3)), whereas cumulative black carbon exposure during the previous 2 to 5 days were significantly associated with ranges in elevations in diastolic blood pressure from 1.3 (0.0-2.5) to 1.7 (0.3-3.2) mm Hg per SD increase (3.6 µg/m(3)). Both black carbon and fine particulate matter were significantly associated with worsening insulin resistance (0.18 [0.01-0.36] and 0.22 [0.04-0.39] unit increase per SD increase of personal-level black carbon and 0.18 [0.02-0.34] and 0.22 [0.08-0.36] unit increase per SD increase of ambient fine particulate matter on lag days 4 and 5). These results provide important global public health warnings that air pollution may pose a risk to cardiometabolic health even at the extremely high concentrations faced by billions of people in the developing world today.

Objectives This study was to analyse evolution of the left ventricular (LV) systolic function assessed by Tissue Doppler imaging (TDI) and its predictive value to the prognosis in Chinese patients with septic shock, and to evaluate the correlation between these parameters and cardiac biomarkers including cardiac tropnin I (cTnI) and N-terminal-pro-BNP (NT-proBNP). Methods This study prospectively recruited 69 patients within 24 h after the onset of septic shock. The clinical variables, cardiac biomarkers and echocardiography data were obtained and analysed on admission (day 1) and at day 2, 4, 7 and 10 or 24 h after the correction of shock. The primary endpoint was 90 days all-cause mortality. Results The 90 days all-cause mortality which was 40.6% in this study. The survivors had a lower peak myocardial systolic velocity (Sm) which emerged as an independent predictor of the 90 days mortality in the multivariate analysis at day 1. There was no difference in the baseline level of biomarkers. During the mean follow-up period of 4.8 days, NT-proBNP and cTnI decreased significantly and Sm improved significantly in the survivors; the non-survivors showed a significantly increased NT-proBNP, unchanged cTnI and Sm. The biomarkers correlated significantly with Sm and LVEF both in the baseline and in the follow-up only in the survivors. The correlation of NT-proBNP with cTnI remained significant throughout the follow-up period in both groups. Conclusions LV systolic function assessed by TDI related to the prognosis of patients with septic shock. The level of biomarkers decreased and strong correlations could be found between the biomarkers and LV systolic function in the 90 days survivors after the onset of septic shock.
