Acute Severe Symptomatic Hyponatremia Following Coronary Angiography

Hyponatremia is a relatively common electrolyte disorder. Although severe acute hyponatremia following coronary angiography is rare, potentially lethal neurologic manifestations may result. We describe a patient with severe, symptomatic hyponatremia, an unusual complication of coronary angiography. Lack of familiarity with contrast media-related hyponatremia caused a delay in diagnosis and therapy in our case. The diagnosis of acute hyponatremia should be considered in any patient who develops behavioral or neurologic manifestations following coronary angiography. Prompt diagnosis and treatment is essential to avoid permanent neurologic damage or death

NICE 2023 Zero-shot Image Captioning Challenge

In this report, we introduce NICE project\footnote{\url{https://nice.lgresearch.ai/}} and share the results and outcomes of NICE challenge 2023. This project is designed to challenge the computer vision community to develop robust image captioning models that advance the state-of-the-art both in terms of accuracy and fairness. Through the challenge, the image captioning models were tested using a new evaluation dataset that includes a large variety of visual concepts from many domains. There was no specific training data provided for the challenge, and therefore the challenge entries were required to adapt to new types of image descriptions that had not been seen during training. This report includes information on the newly proposed NICE dataset, evaluation methods, challenge results, and technical details of top-ranking entries. We expect that the outcomes of the challenge will contribute to the improvement of AI models on various vision-language tasks.Comment: Tech report, project page https://nice.lgresearch.ai

Cardiovascular Parameters Correlated with Metabolic Syndrome in a Rural Community Cohort of Korea: The ARIRANG Study

Although metabolic syndrome (MetS) is associated with increased cardiovascular mortality and the development of atherosclerosis, consensus is still lacking on the status of cardiovascular function and geometry in MetS patients. We investigated the relation between MetS and left ventricle (LV) geometry and function, carotid intima-media thickness (IMT) and arterial stiffness in a community-based cohort of 702 adult subjects. Subjects were categorized into three groups according to the number of MetS components present, as defined by the Adult Treatment Panel III guidelines: 1) Absent (0 criteria), 2) Pre-MetS (1-2 criteria) or 3) MetS (≥3 criteria). In female subjects, LV mass, LV mass/height2.7, deceleration time, and aortic pulse wave velocity increased, and E/A ration decreased in a stepwise manner across the three groups. These changes were not observed in male subjects. The mean carotid IMT was higher in the MetS group than in the other two groups. The degree of MetS clustering is found to be strongly correlated with geometric eccentricity of LV hypertrophy, diastolic dysfunction and arterial changes irrespective of age and blood pressure status, particularly in females. Waist circumference is found to have the most powerful effect on cardiovascular parameters

Hemo-metabolic impairment in patients with ST-segment elevation myocardial infarction: Data from the INTERSTELLAR registry

Background: Not only hemo-dynamic (HD) factors but also hemo-metabolic (HM) risk factors reflecting multi-organ injuries are considered as important prognostic factors in ST-segment elevation myocardial infarction (STEMI). However, studies regarding HM risk factors in STEMI patients are currently limited. Method: Under analysis were 1,524 patients with STEMI who underwent primary percutaneous coronary intervention in the INTERSTELLAR registry. Patients were divided into HM (≥ 2 risk factors) and non-HM impairment groups. The primary outcome was in-hospital all-cause mortality, and the secondary outcome was 1-year all-cause mortality. Results: Of 1,524 patients, 214 (14.0%) and 1,310 (86.0%) patients were in the HM and non-HM impairment groups, respectively. Patients with HM impairment had a higher incidence of in-hospital mortality than those without (24.3% vs. 2.7%, p < 0.001). After adjusting for confounders, HM impairment was independently associated with in-hospital mortality (inverse probability of treatment weighting [IPTW]-adjusted odds ratio: 1.81, 95% confidence interval: 1.08–3.14). In the third door-to-balloon (DTB) time tertile (≥ 82 min), HM impairment was strongly associated with in-hospital mortality. In the first DTB time tertile ( < 62 min), indicating relatively rapid revascularization, HM impairment was consistently associated with increased in-hospital mortality. Conclusions: Hemo-metabolic impairment is significantly associated with increased risk of in-hospital and 1-year mortality in patients with STEMI. It remains a significant prognostic factor, regardless of DTB time

Polymorphic structures of 3-phenyl-1H-1,3-benzodiazol-2(3H)-one

The polymorphic structures (I and II) of 3-phenyl-1H-1,3-benzodiazol-2(3H)-one, C13H10N2O, acquired from pentane diffusion into the solution in THF, are reported. The structures show negligible differences in bond distances and angles, but the C—N—C—C torsion angles between the backbone and the phenyl substituent, 123.02 (15)° for I and 137.18 (11)° for II, are different. Compound I features a stronger C=O...H—N hydrogen bond than that in II, while the structure of II exhibits a stronger π–π interaction than in I, as confirmed by the shorter intercentroid distance [3.3257 (8) Å in II in comparison to 3.6862 (7) Å in I]. Overall, the supramolecular interactions of I and II are distinct, presumably originating from the variation in the dihedral angle
