ABSTRACT

Objective: This study investigated the modified Glasgow prognostic score (mGPS) to determine its predictive value and how it could be compared with various inflammatory markers, including C-reactive protein (CRP) to albumin ratio and neutrophil-to-lymphocyte ratio, for determining the extent and severity of coronary artery disease (CAD) in patients with non-ST-elevated myocardial infarction (NSTEMI). Methods: This study analyzed the cases of 295 patients with NSTEMI who had undergone coronary angiography. In an effort to determine the seriousness and scope of CAD in each patient, the Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score was calculated and then assessed. The study sample was divided into two separate groups based on the SYNTAX score: moderate to high SYNTAX (>22) and low SYNTAX (≤22). Results: There were 295 patients (23.1% female, 76.9% male) included in the research, with an average age being 61.2±10.9 years, and the mean SYNTAX score being 7.3±10.4 (range: 0-40). Those with a SYNTAX score >22 were observed to possess significantly higher levels of CRP, CRP/albumin ratio, and mean mGPS 1-2 ratios compared with those with a SYNTAX score ≤22 (all p<0.001). Smoking [odds ratio (OR): 3.341, 95% confidence interval (CI): 1.531-7.294; p=0.002], CRP/albumin ratio (OR: 4.958, 95% CI: 1.335-18.418; p=0.017), and mGPS score of 1-2 (OR: 3.121, 95% CI: 1.430-6.814; p=0.004) were independent factors used to help predict a high SYNTAX score. Conclusions: It seems possible to make use of the mGPS when estimating the degree and intricacies of CAD in patients with NSTEMI, as there appears to be a connection with higher SYNTAX scores.

ABSTRACT

Female crested gibbons (genus Nomascus) perform conspicuous sequences of twitching movements involving the rump and extremities. However, these dances have attracted little scientific attention and their structure and meaning remain largely obscure. Here we analyse close-range video recordings of captive crested gibbons, extracting descriptions of dance in four species (N. annamensis, N. gabriellae, N. leucogenys and N. siki). In addition, we report results from a survey amongst relevant professionals clarifying behavioural contexts of dance in captive and wild crested gibbons. Our results demonstrate that dances in Nomascus represent a common and intentional form of visual communication restricted to sexually mature females. Whilst primarily used as a proceptive signal to solicit copulation, dances occur in a wide range of contexts related to arousal and/or frustration in captivity. A linguistically informed view of this sequential behaviour demonstrates that movement within dances is organized in groups and follows an isochronous rhythm - patterns not described for visual displays in other non-human primates. We argue that applying the concept of dance to gibbons allows us to expand our understanding of communication in non-human primates and to develop hypotheses on the rules and regularities characterising it. We propose that crested gibbon dances likely evolved from less elaborate rhythmic proceptive signals, similar to those found in siamangs. Although dance displays in humans and crested gibbons share a number of key characteristics, they cannot be assumed to be homologous. Nevertheless, gibbon dances represent a striking model behaviour to investigate the use of complex gestural signals in hominoid primates.

ABSTRACT

Background: A fractional flow reserve (FFR)-fixed-SYNTAX score could decrease the number of high-risk patients. This study explored the prognostic value of non-invasive quantitative flow ratio (QFR)-fixed-SYNTAX I/II scores in multivessel disease patients. Methods: This was a single-center, small-sample, observational study. Multivessel coronary disease patients were enrolled and finished a 1-year follow-up. SYNTAX scores I/II and functional SYNTAX scores I/II based on QFR (cut-off value of 0.85) were calculated for all patients. The composite occurrence of cardiac deaths, any myocardial infarction, or ischemia-driven revascularization were analyzed using a different score system. Results: A total of 160 patients were stratified into risk groups based on a different scoring system. FSS (functional SYNTAX score) and FSSII (functional SYNTAX score II) reduce the radio of high-risk major adverse cardiovascular events (MACEs), transforming the patients from high-risk to medium- and low-risk. Furthermore, FSSII (hazard ratio (HR): 1.069, 95% CI: 1.025-1.115, p = 0.002) showed a better relationship with MACEs than the other score systems. After recalculating SSII, the survival-free ratio stratified by FSSII decreased from 38.46% to 27.27% in the high-risk group and increased from 84.09% to 86.05% in the low-risk group. Conclusions: FSS or FSSII could decrease the number of high-risk patients compared to SYNTAX score (SS) and FSS. SYNTAX II score (SSII) and FSSII showed a better predictive ability than other scoring systems for under-risk stratification.

ABSTRACT

BACKGROUND: Percutaneous coronary intervention (PCI) might improve outcome at severe stages of cardiac allograft vasculopathy (CAV) among patients after heart transplantation (HTx). Yet, risk stratification of HTx patients after PCI remains challenging. AIMS: To assess whether the International Society for Heart and Lung Transplantation (ISHLT) CAV classification remains prognostic after PCI and whether risk-stratification models of non-transplanted patients extend to HTx patients with CAV. METHODS: At 2 European academic centers, 203 patients were stratified in cohort 1 (ISHLT CAV1, without PCI, n = 126) or cohort 2 (ISHLT CAV2 and 3, with PCI). At first diagnosis of CAV or first PCI, respectively, ISHLT CAV grades, SYNTAX scores I and II (SXS-I, SXS-II) were used to quantify baseline and residual CAV (rISHLT, rSXS-I, rSXS-II). RSXS-I > 0 defined incomplete revascularization (IR). RESULTS: SXS-II predicted mortality in cohort 1 (P = 0.004), whereas SXS-I (P = 0.009) and SXS-II (P = 0.002) predicted mortality in cohort 2. Post-PCI, IR (P = 0.004), high rISHLT (P = 0.02) and highest tertile of rSXS-II (P = 0.006) were associated with higher 5-year mortality. In bivariable Cox analysis, baseline SXS-II, IR and rSXS-II remained predictors of 5-year mortality post-PCI. There was a strong inverse relationship between baseline and rSXS-I (r = -0.55; P < 0.001 and r = -0.50; P = 0.003, respectively) regarding the interval to first reintervention. CONCLUSION: People with ISHLT CAV classification could apply for risk stratification after PCI. SYNTAX scores could be complemental for risk stratification and individualization of invasive follow-up of HTx patients with CAV.

ABSTRACT

Aspect-based sentiment analysis (ABSA) is a challenging task due to the presence of multiple aspect words with different sentiment polarities in a sentence. Recently, pre-trained language models like BERT have been widely used as context encoders in ABSA. Graph neural networks have also been employed to extract syntactic and semantic information from sentence parsing trees, resulting in superior results. However, dependency trees may establish irrelevant dependencies for sentences with irregular syntax and complex structures. Additionally, previous methods have not fully utilized recent developments in pre-trained language models. Therefore, we propose a Dual Syntax aware Graph attention networks with Prompt (DSGP) model to address these issues. Our model utilizes prompt templates to maximize the potential of pre-trained models and masked vector outputs of templates as supplementary aspect feature representations. We also leverage both dependency trees and constituent trees with graph attention networks to extract different types of syntactic information. The dependency tree captures syntactic correlation between words, while the constituent tree provides a high-level formation of the sentence. Finally, the output from the prompt and parsing trees is fused and fed into a standard classifier. Experimental results on four public datasets demonstrate the competitive performance of our model.

ABSTRACT

Understanding the nature of traffic accidents in relation to urban access networks is crucial for building safer and more resilient cities. This paper examines the issue of traffic accidents through the lenses of urban configurational theory and urban land use. Three data layers were used in the study, including space syntax analysis conducted in Depthmap X, geotagged traffic accidents collected by the police department, and geotagged land-use data. The method involved superimposing these data layers and exploring potential correlations using a geographic information system (GIS). The findings indicate significant correlations between the spatial frequency of traffic accidents and the choice measure (at 2500 m), local integration, and active land use. The findings of this study can help inform planners and policymakers about the best location to implement safety measures to reduce the risk of traffic accidents in urban access networks.

ABSTRACT

How we combine minimal linguistic units into larger structures remains an unresolved topic in neuroscience. Language processing involves the abstract construction of 'vertical' and 'horizontal' information simultaneously (e.g., phrase structure, morphological agreement), but previous paradigms have been constrained in isolating only one type of composition and have utilized poor spatiotemporal resolution. Using intracranial recordings, we report multiple experiments designed to separate phrase structure from morphosyntactic agreement. Epilepsy patients (n = 10) were presented with auditory two-word phrases grouped into pseudoword-verb ('trab run') and pronoun-verb either with or without Person agreement ('they run' vs. 'they runs'). Phrase composition and Person violations both resulted in significant increases in broadband high gamma activity approximately 300 ms after verb onset in posterior middle temporal gyrus (pMTG) and posterior superior temporal sulcus (pSTS), followed by inferior frontal cortex (IFC) at 500 ms. While sites sensitive to only morphosyntactic violations were distributed, those sensitive to both composition types were generally confined to pSTS/pMTG and IFC. These results indicate that posterior temporal cortex shows the earliest sensitivity for hierarchical linguistic structure across multiple dimensions, providing neural resources for distinct windows of composition. This region is comprised of sparsely interwoven heterogeneous constituents that afford cortical search spaces for dissociable syntactic relations.

ABSTRACT

Aim: The aim of this study was to find out the relationship of conventional and/or novel cardiovascular risk factors with coronary artery disease severity in terms of SYNTAX scores in young (≤45 years) and aged (>45 years) patients. Materials and Methods: The final number of patients included in the study was 132 and divided into 2 groups: Group A was young patients with age less than 45 years, and in group B, the age was more than 45 years. The SYNTAX score was determined for each case based on the preoperative coronary angiogram using the Online SYNTAX score calculator version 2.11. Results: It was seen that 33% of patients in group A had high SYNTAX scores, as compared to only 8% in group B. This definitely shows that the younger population has more COMPLEX coronary artery lesions than the elderly. Conclusion: YOUNG patients have significantly higher levels of homocysteine as compared to the elderly. Serum homocysteine correlates with SYNTAX scores in YOUNG patients, with a sensitivity of 83.33%, specificity 91.67%, and diagnostic accuracy 86.67%. Percentage of Low HDL in YOUNG is significantly higher than in the elderly.

ABSTRACT

A question in language acquisition research is whether attrition can affect L1 grammatical representation, and if so, under what conditions. This paper tests the Attrition via Acquisition (AvA) model, which takes a Feature Reassembly approach to predict how, in case on high degrees of similarity between the L1 and L2, the acquisition of L2 discourse-driven morpho-syntactic properties may affect L1 feature representations after a prolonged change in the speaker's primary linguistic input during adulthood. As a test case, we use the different features (specificity versus discourse anaphoricity) associated with Clitic Left Dislocation (CLLD) in Romanian and Italian, examining the grammars of Romanian first-generation immigrants with either L2 Italian or L2 English (a language without CLLD). Using a context-dependent Acceptability Judgment task and a Written Elicitation task we found evidence for L2-induced grammatical attrition, resulting in the addition of an L2 option without the loss of an L1 option, as predicted by the AvA. Attrition was found for participants who immigrated during adolescence or early adulthood and who are more likely to consider Italian their most proficient and most used language. We compare our findings on attrited L1 grammars to the results of a recent study reporting on near-native L2 Italian and L2 Romanian grammars by Romanian and Italian native speakers. Our findings contribute to an increasing body of literature showing that L1 attriters and L2 learners can end up with very similar grammars and confirm the importance of studying second language acquisition and L1 loss within a broader picture of bilingual development.

ABSTRACT

Objectives: To investigate the long-term mortality of acute coronary syndrome (ACS) patients with multivessel disease according to the level of completeness of revascularization (CR) and high-bleeding risk (HBR) status. Design Setting and Participants: This retrospective study collected the data of ACS patients with multivessel disease who underwent percutaneous coronary intervention between May 2018 and February 2019. Complete to reasonable revascularization (CR) was defined by the residual Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery score (RSS) of 0 to ≤8. The HBR was defined by the PRECISE-DAPT score ≥25. Main Outcome Measures: The all-cause death at 36 months according to the CR and HBR status. Results: A total of 209 patients with 743 lesions were included in the analysis. The median follow-up was 3.6 years. Patients with CR had lower event rates than ICR (4.5 vs. 11.5 per 100 patient-year, HR 0.39, 95% CI 0.22-0.70), p = 0.002). Similar observations were noted when compared between non-HBR and HBR (3.9 vs. 11.1 per 100 patient-year, HR 0.35, 95% CI 0.18-0.64, p < 0.001). Kaplan-Meier analysis revealed that all-cause death was highest among those in the ICR/HBR (40.5%) followed by ICR/non-HBR (28.6%), CR/non-HBR (28.3%) and the lowest among the CR/HBR group (7.1%), log-rank p = <0.001. No significant interaction was observed between the two factors regarding all-cause death (p = 0.10 for interaction). Conclusions: In ACS patients with MVD, the achievement of CR was associated with reducing mortality rates and consistency irrespective of the HBR status. (Trial Registration: TCTR20211222003).

ABSTRACT

BACKGROUND: Inflammation plays a crucial role in the progression of acute coronary syndrome. AIMS: The aim of this study was to investigate the relationship between the SYNTAX score and new inflammatory markers including albumin-globulin ratio (AGR), C-reactive protein-to-albumin ratio (CAR), fibrinogen-to-albumin ratio (FAR), neutrophil-to-albumin ratio (NAR), and neutrophil percentage-to-albumin ratio (NPAR) in STEMI and NSTEMI patients. METHODS: The study involved 53 STEMI and 64 NSTEMI patients, and each patient group was evaluated separately. Multivariate linear regression analysis was utilised to identify independent risk factors associated with SYNTAX scores. RESULTS: Out of the 64 NSTEMI patients, 42 had low SYNTAX score (65.6%), and 22 had high SYNTAX score (34.4%). Patients with high SYNTAX scores had significantly higher levels of age, glucose, fibrinogen, monocyte, and FAR, and lower levels of albumin and total protein. We found that FAR and monocyte levels were independent predictors of the high SYNTAX score. The study also determined that the cut-off value for FAR as 9.99, with a sensitivity of 81% and a specificity of 73% for predicting high SYNTAX score in NSTEMI patients. Out of the 53 STEMI patients, 42 had low SYNTAX score (79.2%), and 11 had high SYNTAX score (20.8%). Patients with high SYNTAX scores exhibited significantly higher total cholesterol, LDL, and glucose levels, and lower albumin and total protein levels. CONCLUSIONS: The FAR level is significantly linked with the high SYNTAX score and can be a useful marker for predicting the severity of disease in NSTEMI patients.

ABSTRACT

A central goal for psychological science is the explanation of variation in human behaviour. In the domain of language, patterns of cross-linguistic variation have been extensively documented, but there has been vigorous debate over how to explain them. A particularly contentious question is whether constraints on linguistic variation are driven by properties of the human mind that are specific to language, or domain general. In this paper, we present four pattern-learning experiments (N=306 English- and Italian-speaking adults) across domains (linguistic and non-linguistic) and modalities (visual, auditory, and tactile) to show that the patterns that are more easily learned are precisely the ones that are found most frequently across languages. This supports a domain-general, cognitive explanation for cross-linguistic variation. However, we suggest that the general/specific dichotomy is ultimately misleading because language structure arises when domain- and modality-general biases meet domain-specific representations.

ABSTRACT

BACKGROUND: To quantify conjunctival microvascular characteristics obtained by optical coherence tomographic angiography (OCTA) and investigate their relationship with the presence and severity of coronary artery disease (CAD). METHODS: This cross-sectional study included 103 consecutive CAD patients confirmed by coronary angiography and 125 non-CAD controls. The temporal conjunctivas along the limbus of each participant were scanned using OCTA. Quantification of conjunctival microvasculature was performed by AngioTool software. The severity of the disease was evaluated using SYNTAX and Gensini scores. RESULTS: Compared to the controls, the CAD group exhibited significantly lower vessel area density (30.22 ± 3.34 vs. 26.70 ± 4.43 %, p < 0.001), lower vessel length density (6.39 ± 0.77 vs. 5.71 ± 0.89/m, p < 0.001), lower junction density (3.44 ± 0.56 vs. 3.05 ± 0.63/m, p < 0.001), and higher lacunarity (0.11 ± 0.03 vs. 0.14 ± 0.05, p < 0.001). Among all participants, lower vessel area density, lower vessel length density, lower junction density, and higher lacunarity were associated with greater odds of having CAD; the adjusted ORs (95 % confidence intervals) per one SD decrease were 2.71 (1.71, 4.29), 2.51(1.61, 3.90), 2.06 (1.39, 3.05), and 0.36 (0.23, 0.58), respectively. Among CAD patients, junction density was negatively associated with the Gensini score (r = -0.359, p = 0.037) and the Syntax score (r = -0.350, p = 0.042) in women but not in men (p > 0.05). CONCLUSIONS: Conjunctival microvascular characteristics were significantly associated with the presence of CAD. Junction density significantly associated with the severity of CAD among women patients.

ABSTRACT

BACKGROUND: This study addresses the challenges in hospital navigation, particularly focusing on the sequence of arrival experiences through foot traffic or driving within a medical campus. While previous research has emphasized wayfinding in interiors, this study recognizes the importance of transition from outdoor to indoor spaces in the hospital arrival zone. OBJECTIVES: Twofold research efforts include: (1) Exploring vehicular and pedestrian behaviors in a hospital arrival zone using Space Syntax Analyses (SSA), and (2) Validating the SSA results using empirical data collected from onsite observations and behavior mapping. METHODS: A series of axial map analyses were conducted on the hospital campus and building arrival zone regarding spatial connectivity and integration, depth of spaces, and wayfinding intelligibility based on vehicular and pedestrian movement paths. Systematic behavioral data collection includes vehicle shadowing (10 h) and pedestrian mapping (20 h) in the building arrival zone. RESULTS: Space Syntax Analyses indicates high intelligibility scores for vehicles (R = .91) and pedestrian (R = .78) circulation patterns; traffic situations were visualized via axial maps. A dataset of 219 vehicles and 2,096 pedestrian behaviors was analyzed and visualized using diagrams and heatmaps, identifying different occupancy patterns within the space. Correlational analyses indicated strong correlations between the results: connectivity and integration scores are significantly correlated with both vehicular and pedestrian traffic volumes. CONCLUSION: Preliminary findings of the study validated an integrated protocol to evaluate the impacts of campus configuration and building approach design on patient arrival and spatial navigation at large hospitals, serving as a POE protocol involving SSA.

ABSTRACT

BACKGROUND: There is uncertainty regarding the best revascularization approach-whether coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI)-for obese patients suffering from multi-vessel coronary artery disease. RESULTS: 406 patients with low and intermediate SYNTAX scores (SS) underwent PCI with drug-eluting stents (n = 200, 100 with SS ≤ 22, and 100 with SS 23-32) and CABG (n = 206, 100 with SS ≤ 22, and 106 with SS 23-32). Patients were also categorized by body mass index (BMI): normal weight (12%, 48 patients), overweight (41.6%, 169 patients), and obese (46.6%, 189 patients). The follow-up period averaged 9 ± 1.9 years. The endpoints of the study were as follows: major adverse cardiac and cerebrovascular events, a repeat revascularization, diminished left ventricular ejection fraction (LVEF), and high SS (≥ 33) observed over time. When comparing PCI and CABG in overweight individuals, the risk of myocardial infarction (MI) following PCI was greater than after CABG (Hazard Ratio [HR] 2.7, 95% Confidence Interval [CI] 1.1-6.7, p = 0.03). In patients with overweight and Class I obesity, CABG was associated with the risk of coronary atherosclerosis progression (SS ≥ 33) (HR 4.4, 95% CI 1.5-13, p = 0.009 and HR 4.9, 95% CI 1.9-12, p = 0.001, respectively); whereas PCI was connected with the likelihood of repeat revascularization (HR 2.7, 95% CI 1.6-4.55, p < 0.0001 and HR 2, 95% CI 1.3-3.1, p = 0.002, respectively). At the same time, for stented patients, Class III obesity was associated with the risk of repeat revascularization (HR 2.5, 95% CI 1.02-6, p = 0.044). CONCLUSION: There were no significant weight-related impacts on long-term outcomes among patients who underwent surgery. Whereas in stented patients, Class III obesity was associated with the risk of repeat revascularization. When comparing PCI and CABG, for overweight and Class I obesity patients, CABG was associated with a likelihood of coronary atherosclerosis progression (SS ≥ 33), while PCI was linked to the risk of repeat revascularization. For overweight patients, CABG outperformed PCI in terms of the risk of MI. For other adverse events in patients of different weight categories, PCI and CABG did not reveal any significant benefits.

ABSTRACT

Acoustic, lexical, and syntactic information are simultaneously processed in the brain requiring complex strategies to distinguish their electrophysiological activity. Capitalizing on previous works that factor out acoustic information, we could concentrate on the lexical and syntactic contribution to language processing by testing competing statistical models. We exploited electroencephalographic recordings and compared different surprisal models selectively involving lexical information, part of speech, or syntactic structures in various combinations. Electroencephalographic responses were recorded in 32 participants during listening to affirmative active declarative sentences. We compared the activation corresponding to basic syntactic structures, such as noun phrases vs. verb phrases. Lexical and syntactic processing activates different frequency bands, partially different time windows, and different networks. Moreover, surprisal models based on part of speech inventory only do not explain well the electrophysiological data, while those including syntactic information do. By disentangling acoustic, lexical, and syntactic information, we demonstrated differential brain sensitivity to syntactic information. These results confirm and extend previous measures obtained with intracranial recordings, supporting our hypothesis that syntactic structures are crucial in neural language processing. This study provides a detailed understanding of how the brain processes syntactic information, highlighting the importance of syntactic surprisal in shaping neural responses during language comprehension.

ABSTRACT

Background: Earlier research focuses primarily on the cognitive changes due to Alzheimer's disease (AD); however, little is known with regard to changes in language competence across the lifespan. Objective: The present study aims to investigate the decline of language skills at the grammatical and syntactic levels due to changes in cognitive function. Methods: We administered the Litmus Sentence Repetition Task (SRT) to 150 native speakers of Greek who fall into five groups: 1) young healthy speakers, 2) cognitively intact elder healthy speakers, 3) speakers with subjective cognitive impairment (SCI), 4) speakers with mild cognitive impairment (MCI); and 5) speakers with AD dementia at the mild/moderate stages. All participants underwent a physical and neurological examination and cognitive screening with a standardized neuropsychological battery to assess cognitive status comprehensively and evaluate aspects like working memory, executive function, attention and memory to appropriately classify them. Results: The data analysis revealed that the SRT had high discriminatory value in the development of AD; specifically, both accuracy and grammaticality indices were related to cognitive decline. Additionally, syntax significantly affected the performance of speakers with structures such as clitics being particularly challenging and in most structures the performance of speakers with MCI drops significantly compared to speakers with SCI. Conclusions: Linguistic indices revealed subtle early signs of cognitive decline that can be helpful in the early detection of AD, thus facilitating the clinical process offering support to language-based assessment tools such as sentence repetition, a non-invasive type of assessment to evaluate symptoms of AD.

ABSTRACT

The acquisition of an acoustic template is a fundamental component of vocal imitation learning, which is used to refine innate vocalizations and develop a species-specific song. In the absence of a model, birds fail to develop species typical songs. In zebra finches (Taeniopygia guttata), tutored birds produce songs with a stereotyped sequence of distinct acoustic elements, or notes, which form the song motif. Songs of untutored individuals feature atypical acoustic and temporal structure. Here we studied songs and associated respiratory patterns of tutored and untutored male zebra finches to investigate whether similar acoustic notes influence the sequence of song elements. A subgroup of animals developed songs with multiple acoustically similar notes that are produced with alike respiratory motor gestures. These birds also showed increased syntactic variability in their adult motif. Sequence variability tended to occur near song elements which showed high similarity in acoustic structure and underlying respiratory motor gestures. The duration and depth of the inspirations preceding the syllables where syntactic variation occurred did not allow prediction of the following sequence of notes, suggesting that the varying duration and air requirement of the following expiratory pulse is not predictively encoded in the motor program. This study provides a novel method for calculation of motor/acoustic similarity, and the results of this study suggest that the note is a fundamental acoustic unit in the organization of the motif and could play a role in the neural code for song syntax.

ABSTRACT

BACKGROUND: In patients presenting with ST-segment elevation myocardial infarction (STEMI), the prevalence of having concomitant severe non-culprit lesion(s) is ≥40%. While timely primary PCI (pPCI) for the culprit lesion is the standard practice, management of the non-culprit lesions remains unsettled. RESULTS: This prospective multi-center observational study recruited 492 acute STEMI patients who underwent successful pPCI for the culprit lesion. Culprit-only versus complementary non-culprit lesion(s) PCI (either immediate or staged during the same hospital stay) was according to the operator's discretion. Clinical, echocardiographic, and angiographic data were collected and tabulated. The residual SYNTAX score (rSS) was completed by the time of discharge considering the residual lesions after all in-hospital revascularization procedures. Through a minimum follow-up of 12 months, older age, presentation with heart failure Killip class ≥ II, lower estimated glomerular filtration rate (eGFR) on admission, lower left ventricular ejection fraction (LVEF), and higher rSS by discharge were significantly associated with recurrent MACE. In multivariate regression analysis, Killip class ≥ II, LVEF, and rSS were found to be independent predictors for recurrent MACE. In the Receiver Operating Characteristics curve, an rSS of >8 had a sensitivity of 70.1%, and specificity of 75.3% to predict 1-year MACE. CONCLUSIONS: Residual syntax score proved to be an independent predictor for recurrent MACE through the subsequent year post STEMI. Patients with rSS >8 seem to be at the highest risk for adverse events and are likely to be the most deserving for completing revascularization to reduce the disease burden.

ABSTRACT

Objects and places are foundational spatial domains represented in human symbolic expressions, like drawings, which show a prioritization of depicting small-scale object-shape information over the large-scale navigable place information in which objects are situated. Is there a similar object-over-place bias in language? Across six experiments, adults and 3- to 4-year-old children were asked either to extend a novel noun in a labeling phrase, to extend a novel noun in a prepositional phrase, or to simply match pictures. To dissociate specific object and place information from more general figure and ground information, participants either saw scenes with both place information (a room) and object information (a block in the room), or scenes with two kinds of object information that matched the figure-ground relations of the room and block by presenting an open container with a smaller block inside. While adults showed a specific object-over-place bias in both extending novel noun labels and matching, they did not show this bias in extending novel nouns following prepositions. Young children showed this bias in extending novel noun labels only. Spatial domains may thus confer specific and foundational biases for word learning that may change through development in a way that is similar to that of other word-learning biases about objects, like the shape bias. These results expand the symbolic scope of prior studies on object biases in drawing to object biases in language, and they expand the spatial domains of prior studies characterizing the language of objects and places.
