Abstract
In February 2018, a 67-year-old male patient with infected abdominal aortic aneurysm was admitted to the Department of Vascular Surgery of Yantai Yuhuangding Hospital Affiliated to Qingdao University Medical College. After admission, abdominal aortic endovascular exclusion surgery, right iliac artery-double femoral artery vascular bypass+ infected abdominal aortic aneurysmectomy+ stent removal surgery, and active anti-infective treatment were performed in the department of vascular surgery. Seven days after the vascular prosthesis bypass surgery, the surface skin of the vascular prosthesis of the patient was red and swollen, and there was a purulent discharge, which was diagnosed as poor healing of sinus of vascular prosthesis. Surgeons of our department and the department of vascular surgery performed incision and debridement of sinus of vascular prosthesis+ vacuum sealing drainage (VSD) in the early stage under local anesthesia. After the local infection was controlled and wound blood supply was improved, stage Ⅱ surgery of resection of sinus of vascular prosthesis+ vascular prosthesis partial diversion+ local flap propulsion under general anesthesia was performed. The incision healed well after surgery, and the patient was discharged smoothly. During the follow-up of 6 months, the patient's flap was in good shape, and the wound was healed. This case prompts that after the diagnosis of infected abdominal aortic aneurysm vascular sinus poor healing, we can actively open the infected sinus, use VSD technology to treat granulation wounds, then divert the implanted vascular prosthesis to prepare fresh local flap which covers the vascular prosthesis, and use new silver ion dressing to cover the wounds, thus achieving satisfactory results.

Abstract
The welfare and healthy growth of poultry under intensive feeding conditions are closely related to their living environment. In spring, the air quality considerably decreases due to reduced ventilation and aeration in cage systems, which influences the meat quality and health of broilers during normal growth stages. In this study, we analyzed the airborne bacterial communities in PM2.5 and PM10 in cage broiler houses at different broiler growth stages under intensive rearing conditions based on the high-throughput 16S rDNA sequencing technique. Our results revealed that PM2.5, PM10 and airborne microbes gradually increased during the broiler growth cycle in poultry houses. Some potential or opportunistic pathogens, including Acinetobacter, Pseudomonas, Enterococcus, Microbacterium, etc., were found in the broiler houses at different growth stages. Our study evaluated variations in the microbial communities in PM2.5 and PM10 and potential opportunistic pathogens during the growth cycle of broilers in poultry houses in the spring. Our findings may provide a basis for developing technologies for air quality control in caged poultry houses.

Abstract
AIMS The aim of this study is to investigate Streptococcus suis strains present in Jiangsu province, China. METHODS AND RESULTS In all, 1650 nasal and anal swab samples and 100 tonsils were collected from clinically healthy swine. Culture characteristics, colony morphology and PCR-based analysis of the glutamate dehydrogenase (gdh) gene were performed for S. suis identification, and eight isolates were confirmed to be S. suis. The isolates serogroups were identified by agglutinating test, including 4, 7, 3, 5 and 8. Gene profiling by PCR showed that the manN, purD, orf2, gdh genes were conserved among the isolates and that 50% of the isolates carried dltA, pgdA, srtA and sspA. Antimicrobial susceptibility test showed the isolates displayed resistance to clindamycin, erythromycin, tetracycline, penicillin G, vancomycin and linezolid; while none was resistant to chloramphenicol, multi-drug resistance was seen in most of the isolates. Finally, the LD50 (assessed by zebrafish) of isolates RD105 was 2·6431 × 105 and HA24 was 7·1198 × 106 , which showed RD105 more virulent and was consistent with the results of virulence factor identification. CONCLUSIONS There is a very low proportion of S. suis in the healthy pigs. The virulence factors were related to pathogenicity. Bacteria in Nantong possess greater virulence potential than those in Huaian. SIGNIFICANCE AND IMPACT OF THE STUDY Systematic investigation of S. suis provided the most basic theoretical support for the prevention and control of swine streptococcosis.

Abstract
The study aimed to investigate whether sulforaphane (SFN) protects against angiotensin II (Ang II)-mediated human umbilical vein endothelial cell (HUVEC) injury. Ang II treatment decreased HUVEC viability, increased cell apoptosis, decreased mitochondria membrane potential (MMP), impaired cytochrome c release, activated caspase 3/9, and induced reactive oxygen species (ROS) production, and nicotinamide adenine dinucleotide phosphate oxidase activity. Moreover, SFN treatment blunted Ang II-stimulated oxidative stress and mitochondria-related apoptosis in HUVECs. The ROS scavenger N-acetyl-l-cysteine reduced Ang II-induced oxidative stress and apoptosis, indicating that ROS generation is involved in the Ang II-induced mitochondria-mediated apoptotic pathway. SFN induced nuclear factor erythroid 2 (Nrf2) activation and expression in Ang II-stimulated HUVECs. Downregulation of Nrf2 expression by a target-specific siRNA revealed an Nrf2-dependent effect on the SFN-mediated attenuation of Ang II-induced apoptosis in HUVECs. Pretreatment with brusatol, an Nrf2-specific inhibitor, reversed the protective effects of SFN on Ang II-induced HUVEC injury. SFN treatment protected HUVECs from Ang II-induced damage by decreasing oxidative stress and ameliorating mitochondrial injury.

Abstract
WSL8 encoding a deoxyribonucleoside kinase (dNK) that catalyzes the first step in the salvage pathway of nucleotide synthesis plays an important role in early chloroplast development in rice. The chloroplast is an organelle that converts light energy into chemical energy; therefore, the normal differentiation and development of chloroplast are pivotal for plant survival. Deoxyribonucleoside kinases (dNKs) play an important role in the salvage pathway of nucleotides. However, the relationship between dNKs and chloroplast development remains elusive. Here, we identified a white stripe leaf 8 (wsl8) mutant that exhibited a white stripe leaf phenotype at seedling stage (before the four-leaf stage). The mutant showed a significantly lower chlorophyll content and defective chloroplast morphology, whereas higher reactive oxygen species than the wild type. As the leaf developed, the chlorotic mutant plants gradually turned green, accompanied by the restoration in chlorophyll accumulation and chloroplast ultrastructure. Map-based cloning revealed that WSL8 encodes a dNK on chromosome 5. Compared with the wild type, a C-to-G single base substitution occurred in the wsl8 mutant, which caused a missense mutation (Leu 349 Val) and significantly reduced dNK enzyme activity. A subcellular localization experiment showed the WSL8 protein was targeted in the chloroplast and its transcripts were expressed in various tissues, with more abundance in young leaves and nodes. Ribosome and RNA-sequencing analysis indicated that some components and genes related to ribosome biosynthesis were down-regulated in the mutant. An exogenous feeding experiment suggested that the WSL8 performed the enzymic activity of thymidine kinase, especially functioning in the salvage synthesis of thymidine monophosphate. Our results highlight that the salvage pathway mediated by the dNK is essential for early chloroplast development in rice.

Abstract
There has been a recent surge of interest and progress in creating subwavelength free-space optical potentials for ultracold atoms. A key open question is whether geometric potentials, which are repulsive and ubiquitous in the creation of subwavelength free-space potentials, forbid the creation of narrow traps with long lifetimes. Here, we show that it is possible to create such traps. We propose two schemes for realizing subwavelength traps and demonstrate their superiority over existing proposals. We analyze the lifetime of atoms in such traps and show that long-lived bound states are possible. This work allows for subwavelength control and manipulation of ultracold matter, with applications in quantum chemistry and quantum simulation.

Abstract
Accumulating evidence has supported an increased risk of osteoporotic fracture in postmenopausal women and elderly men diagnosed with diabetes mellitus. However, it is not uncommon for young and middle-aged male patients diagnosed with type 2 diabetes mellitus (T2DM) to suffer from osteopenia or osteoporosis. Few studies focused on this population group are available. The aim of this study is to evaluate bone metabolic status and investigate the influence of T2DM on bone metabolism in 30-50-year-old men. Anthropometric assessment and blood samples were obtained from 160 patients with T2DM and 69 nondiabetic volunteers. Serum parathyroid hormone (PTH) and bone turnover markers (BTMs), including serum procollagen type I N-terminal peptide (PINP), osteocalcin (OC), and β-cross-linked C-telopeptide of type I collagen (β-CTX), were analysed. No significant differences were observed based on age, body mass index, systolic blood pressure, serum calcium, phosphorus, creatinine, total protein, and albumin levels when comparing T2DM and control groups. Fasting blood glucose, HbA1c, triglyceride (TG), total cholesterol, and low-density lipoprotein cholesterol were significantly increased, while high-density lipoprotein cholesterol was significantly decreased in the T2DM group. Compared with controls, diabetic patients showed lower serum PINP, OC, and PTH levels, whereas serum β-CTX levels were similar between the two groups. Moreover, HbA1c levels were positively correlated with PINP and inversely associated with PTH levels. TG levels were negatively correlated with OC or β-CTX levels. Furthermore, multiple linear regression revealed a positive correlation between HbA1c and PINP levels. These results also revealed a negative association between HbA1c and PTH, and between TG and OC levels, even after adjusting for expected confounder factors. Collectively, these findings indicated that young and middle-aged male patients with T2DM showed a lower turnover state resulting from bone formation inhibition. Glucose and lipid metabolic disorders may affect bone formation through different pathways.

Abstract
Abstract With the development of new technologies, such as whole genome sequencing and big data, many countries have constructed large cohorts as strategic resources for precision medicine study. Related studies have significantly promoted research progress in many fields, such as medicine and biology, creating the genetic testing industry. In the forensic field, characterization technologies for features, such as biogeographic ancestry, genetic genealogy and physical appearance have emerged and developed rapidly. Compared with traditional forensic DNA technology, the new technology can search for characteristics and provide clues, quickly becoming an important means to solve difficult cases such as cold cases and accumulated cases. This paper briefly reviews the current status of the construction of large cohorts at home and abroad, and the research progress of forensic molecular phenotyping in the context of precision medicine in the context of precision medicine.

Abstract
OBJECTIVE Treatment of the high-risk triple negative breast cancer (TNBC) is a critical clinical challenge. Here we aimed to explore a novel strategy for TNBC treatment by blocking the tumor-associated chemokine CXCL13 in the MDA-MB-231 TNBC cells. MATERIALS AND METHODS MDA-MB-231 cells were treated with anti-CXCL13 antibodies (inhibition group), or phosphate-buffered saline (PBS) (control group), followed by determining the levels of interleukin-1 (IL-1), tumor necrosis factor-alpha (TNF-α) and transforming growth factor beta-1 (TGF-β1) with enzyme-linked immunosorbent assay (ELISA). The effects of CXCL13 inhibition on cell proliferation and apoptosis were assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay and flow cytometry, respectively. Quantitative Real Time-PCR (qRT-PCR) and Western blot were used to compare the levels of CXCL13, CXCR5, extracellular signal-regulated kinase (ERK). The levels of cyclin D1 and cleaved caspase-9 were detected by Western blot. RESULTS The levels of IL-1, TNF-α and TGF-β1 in MDA-MB-231 cells treated with anti-CXCL13 antibodies were significantly downregulated (p<0.05). Meanwhile, CXCL13 blockade decreased the cell proliferation and increased the apoptosis rate of MDA-MB-231 cells. The inhibition of CXCL13 led to marked reduction in CXCL13 and CXCR5 mRNA and an increase in ERK mRNA. The inhibition of CXCL13 resulted in the downregulation of CXCL13, CXCR5, p-ERK/ERK, cyclin D1 and upregulation of cleaved caspase-9 proteins. CONCLUSIONS CXCL13 blockade effectively suppressed the proliferation of MDA-MB-231 cells by promoting cell apoptosis. This effect is presumably associated with the downregulation of CXCL13 and suppression of the CXCR5/ERK signaling pathway.

Abstract
Nine laboratories participated in an interlaboratory method performance (collaborative) study of a method for the determination of sodium in foods by flame atomic absorption spectrometry after wet digestion, using a microwave oven technique. Before the study, the laboratories were able to practice on samples with defined sodium levels (pretrial test). The method was tested on a total of 6 foods (broccoli, carrot, bread, saithe fillet, pork, and cheese) with sodium concentrations of 1480–8260 mg/kg. The materials were presented to the participants in the study as blind duplicates, and the participants were asked to perform single determinations for each sample. The repeatability relative standard deviations (RSDr) for sodium ranged from 1.9 to 6.5%. The reproducibility relative standard deviations (RSDR) ranged from 4.2 to 6.9%. The HorRat values ranged from 0.9 to 1.6.

Abstract
Objectives To investigate the prevalence, clinical characteristics, and prognosis of thrombocytopenia (TP) in Chinese patients with systemic lupus erythematosus (SLE). Methods The study was conducted based on the Chinese SLE Treatment and Research group (CSTAR) registry. Thrombocytopenia was defined as the platelet count<100,000/mm3 at enrollment. Severe thrombocytopenia was defined as the platelet count<50,000/mm3. The prevalence of SLE-related TP, the associations of thrombocytopenia with demographic data, organ involvements, laboratory findings, disease activity, damage, and mortality were investigated. Results Of 2104 patients with SLE, 342 patients (16.3%) were diagnosed with thrombocytopenia. The prevalence of neuropsychiatric SLE, vasculitis, myositis, nephritis, mucocutaneous lesions, pleuritis, fever, leukocytopenia and hypocomplementemia were significantly higher in patients with thrombocytopenia (p<0.05). SLE disease activity index (SLEDAI) was significantly higher in patients with thrombocytopenia (p<0.05). Multivariate analysis showed that leukocytopenia (OR = 2.644), lupus nephritis (OR = 1.539), hypocomplementemia (OR = 1.497) and elevated SLEDAI (OR = 1.318) were independently associated with thrombocytopenia (p<0.05). Long disease duration (OR = 1.006) was an independent risk factor of severe thrombocytopenia, while anti-rRNP (OR = 0.208) was an independent protective factor of severe thrombocytopenia (p<0.05). Long disease duration was an independent risk factor of mortality in patients with thrombocytopenia (RR = 1.006). The 6-year survival of patients with thrombocytopenia was significantly lower than patients without thrombocytopenia (88.2% vs. 95.5%). Conclusions Thrombocytopenia was a common manifestation of SLE and was associated with leukocytopenia, nephritis and severe disease activity. Severe thrombocytopenia tended to occur in long-term and relatively inactive SLE. Patients with SLE-related thrombocytopenia has a decreased long-term survival rate. Long disease duration was an independent risk factor of mortality in patients with thrombocytopenia.

Abstract
BACKGROUND This study aims to evaluate the feasibility and efficacy of a complex health intervention, based on the combination of conventional Western medicine and traditional Chinese medicine (TCM), in an outpatient department of a university hospital for patients with frequent episodic or chronic tension-type headaches. METHODS/DESIGN This is a prospective randomized controlled pilot study with four balanced treatment arms (usual care, acupuncture, training, and training plus acupuncture). Each arm will have 24 patients. After the initial screening examination and randomization, a 6-week treatment period follows, with treatment frequencies decreasing at 2-week intervals. After completion of the intervention, two follow-up evaluations will be performed 3 and 6 months after the start of treatment. At predefined times, the various outcomes (pain intensity, health-related quality of life, pain duration, autonomic regulation, and heart rate variability) as well as the participants' acceptance of the complex treatment will be evaluated with valid assessment instruments (Migraine Disability Assessment, PHQ-D, GAD-7, and SF-12) and a headache diary. The acupuncture treatment will be based on the rules of TCM, comprising a standardized combination of acupuncture points and additional points selected according to individual pain localization. The training therapy comprises a combination of strength training, endurance training, and training to improve flexibility and coordination. Besides descriptive analyses of the samples, their comparability will be assessed using an analysis of variance (ANOVA) or chi-squared tests. Analyses will be performed on an intention-to-treat basis. Potential interaction effects will be calculated using a repeated-measures ANOVA to test the primary and secondary hypotheses. In supplementary analyses, the proportion of treatment responders (those with a 50% reduction in the frequency of pain episodes) will be determined for each treatment arm. DISCUSSION This trial may provide evidence for the additive effects of acupuncture and medical training therapy as a combination treatment and may scientifically support the implementation of this complex health intervention.

Abstract
The prostate is a walnut-sized gland that surrounds the urethra of males at the base of the bladder comprising a muscular portion, which controls the release of urine, and a glandular portion, which secretes fluids that nourish and protect sperms. Here, we report the development of a microfluidic-based model of a human prostate gland. The polydimethylsiloxane (PDMS) microfluidic device, consisting of two stacked microchannels separated by a polyester porous membrane, enables long-term in vitro cocultivation of human epithelial and stromal cells. The porous separation membrane provides an anchoring scaffold for long-term culturing of the two cell types on its opposite surfaces allowing paracrine signaling but not cell crossing between the two channels. The microfluidic device is transparent enabling high resolution bright-field and fluorescence imaging. Within this coculture model of a human epithelium/stroma interface, we simulated the functional development of the in vivo human prostate gland. We observed the successful differentiation of basal epithelial cells into luminal secretory cells determined biochemically by immunostaining with known differentiation biomarkers, particularly androgen receptor expression. We also observed morphological changes where glandlike mounds appeared with relatively empty centers reminiscent of prostatic glandular acini structures. This prostate-on-a-chip will facilitate the direct evaluation of paracrine and endocrine cross talk between these two cell types as well as studies associated with normal vs disease-related events such as prostate cancer.

Abstract
Mono(2-ethylhexyl) phthalate (MEHP) is the main metabolite of di(2-ethylhexyl) phthalate (DEHP) in organisms and is commonly used as a plasticizer. Exposure to DEHP impairs the function of islet beta cells (INS-1 cells), which is related to insulin resistance and type 2 diabetes. At present, some research data have also confirmed that MEHP has a certain damage effect on INS-1 cells. In our experiment, we found that MEHP would lead to the increase of reactive oxygen species (ROS) and the upregulation of autophagy. And downregulated ROS production by N-acetyl-L-cysteine could also reduce autophagy. In addition, MEHP-induced lysosomal membrane permeability (LMP) subsequently released cathepsin D. Additionally, MEHP induced the collapse of mitochondrial transmembrane potential and release of cytochrome c. Addition of autophagy inhibitor 3-methyladenine relieved MEHP-induced apoptosis as assessed by the expression of cleaved caspase 3, cleaved caspase 9, and terminal deoxynucleotidyl transferase dUTP nick end labeling assay, indicating that MEHP-induced apoptosis was autophagy dependent. Cathepsin D inhibitor, pepstatin A, suppressed MEHP-induced mitochondria release of cytochrome c and apoptosis as well. Meanwhile, pyrroloquinoline quinone (PQQ), a new B vitamin, improved the above phenomenon. Taken together, our results indicate that MEHP induces autophagy-dependent apoptosis in INS-1 cells by lysosomal-mitochondrial axis. PQQ improved this process by downregulating ROS and provided a degree of protection. Our study provides a new perspective for MEHP on the cytotoxic mechanism and PQQ protection in INS-1 cells.

Abstract
Objective: To compare the clinical characteristics and long-term prognosis between male and female patients with premature coronary artery disease (PCAD) post coronary intervention, and analyse the risk factors of major adverse cardio-cerebrovascular events (MACCE) and bleeding events. Methods: This was a prospective single-center observational study. From January 2013 to December 2013, 4 744 patients diagnosed as PCAD and treated with percutaneous coronary intervention (PCI) in Fuwai Hospital were enrolled. The general clinical data, laboratory results and interventional treatment data of all patients were collected, and patients were followed up for 2 years after PCI and the incidence of events including MACCE and bleeding was analyzed. The baseline data and clinical events of PCAD patients of different genders were compared. Survival curves were estimated by Kaplan-Meier method. Univariate and multivariate Cox regression were used to analyze whether gender was an influencing factor of different clinical events of PCAD patients within 2 years after PCI, and other relevant influencing factors of MACCE and bleeding events. Results: Among the 4 744 PCAD patients included, there were 3 390 (71.5%) male aged (47.0±5.4) years old and 1 354 (28.5%) female aged (57.0±5.8) years old. Compared with female patients, male patients had higher body mass index, higher proportion of hyperlipidemia, smoking, myocardial infarction, previous PCI, preoperative estimated glomerular filtration rate, ST-segment elevation myocardial infarction, radial artery approach, intravenous ultrasound use and chronic occlusive lesions (all P<0.05). Age, left ventricular ejection fraction, prevalence of hypertension, diabetes mellitus, past stroke history, non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and the use of calcium channel blockers were lower in male patients than in female patients (all P<0.05). The 2-year follow-up results showed that the incidence of BARC type 1 hemorrhage was significantly higher in female patients than in male patients (6.9%(92/1 343) vs. 3.7%(126/3 378), P<0.001); however, the incidence of MACCE, all-cause death, cardiac death, recurrent myocardial infarction, revascularization (target vessel revascularization and target lesion revascularization), stent thrombosis, stroke and BARC type 2-5 hemorrhage were similar between the two groups (all P>0.05). Multivariate Cox regression analysis showed that gender was an independent risk factor for BARC type 1 bleeding in PCAD patients (HR=2.180, 95%CI 1.392-3.416, P<0.001), but it was not an independent risk factor for MACCE and BARC type 2-5 bleeding(all P>0.05). Hyperlipidemia, preoperative SYNTAX score, multivessel lesions and NSTE-ACS were the independent risk factors for MACCE in PCAD patients with PCI (the HRs(95%CI) were 1.289(1.052-1.580), 1.030(1.019-1.042), 1.758(1.365-2.264), 1.264(1.040-1.537), respectively); gender (HR=1.579, 95%CI 1.085-2.297, P=0.017), hyperlipidemia (HR=1.305, 95%CI 1.005-1.695, P=0.046), anticoagulant drugs including low molecular weight heparin (HR=1.321, 95%CI 1.002-1.741, P=0.048) or sulfonate(HR=1.659, 95%CI 1.198-2.298, P=0.002) were the independent risk factors for bleeding events. Conclusions: There are differences in clinical and coronary artery lesion characteristics between different genders in patients with PCAD. The incidence of minor bleeding is significantly higher in female PCAD patients than in male PCAD patients. Hyperlipidemia, preoperative SYNTAX score, multivessel lesions and NSTE-ACS are the independent risk factors for MACCE, and gender, hyperlipidemia, anticoagulant drugs including low molecular weight heparin or sulfonate are the independent risk factors for bleeding events in patients with PCAD.

Abstract
Abstract
Background
Hypoalbuminemia was reported to be associated with poor prognosis in severe diseases. Triple-vessel coronary artery disease (TVD) has high risk of death. We aimed to evaluate the predictive value of hypoalbuminemia in TVD patients.
Methods
A total of 8,943 consecutive TVD patients were enrolled from April 2004 to February 2011. The primary endpoint was all-cause death and the secondary endpoints were major adverse cardiovascular and cerebrovascular events (MACCE; a composite of all-cause death, myocardial infarction or stroke). Patients were divided into two groups according to normal serum albumin level (<4.0 g/dL and ≥4.0 g/dL).
Results
During the median of follow-up 7.5 years, 1365 deaths and 2354 MACCE occurred. Multivariate Cox regression indicated that hypoalbuminaemia (<4.0 g/dL) was an independent predictor of all-cause death (HR 1.30, 95% CI 1.14–1.50, P<0.001) and MACCE (HR 1.19, 95% CI 1.07–1.32, P<0.001). Adjustment of the all-cause death risk estimated by albumin improved the predictive value of SYNTAX score (AUC from 0.585 to 0.602, P=0.002; IDI=0.005, P<0.001; NRI=0.205, P<0.001). For SYNTAX II score, improvement was shown for NRI and IDI but not for AUC (SYNTAX II for PCI: IDI=0.003, P<0.001; NRI=0.205, P<0.001; AUC from 0.711 to 0.713, P=0.257; SYNTAX II for CABG: IDI=0.002, P<0.001; NRI=0.205, P<0.001; AUC from 0.696 to 0.698, P=0.120).
Predictive value for all-cause death using the AUC, NRI and IDI AUC (95% CI) P value NRI (95% CI) P value IDI (95% CI) P value SYNTAX 0.585 (0.568–0.602) Ref.

Ref. – Ref. – SYNTAX II (for PCI) + albumin 0.713 (0.698–0.728) 0.257 0.205 (0.145–0.264) <0.001 0.003 (0.001–0.004) <0.001 SYNTAX II (for CABG) 0.696 (0.680–0.711) Ref. Ref. – Ref. – SYNTAX II (for CABG) + albumin 0.698 (0.683–0.714) 0.120 0.205 (0.145–0.264) <0.001 0.002 (0.001–0.004) <0.001
Multi-factor adjusted KM analysis in TVD
Conclusions
For TVD patients, hypoalbuminaemia was a strong independent prognostic factor for long-term outcomes of death and MACCE. Albumin improved the prediction of death with the SYNTAX score and the SYNTAX II score.
