Two dimensions of narcissism were related to psychophysiological responses to stress in 50 young women. Cardiovascular, electrodermal, task performance, and stress appraisal measures were recorded during rest, mental arithmetic, and a computerized Thematic Apperception Test (Murray, 1943). The Egocentricity and Alienation scales of the Bell Object Relations and Reality Testing Inventory (Bell, 1995) served as measures of overt/inflated and covert/deflated narcissism. Egocentricity correlated consistently with heightened preejection period reactivity, whereas Alienation correlated consistently with diminished electrodermal reactivity (all p < .05). Multivariate analyses supported specific relationships between Egocentricity and preejection period hyperreactivity, and between Alienation and electrodermal hyporeactivity. These results have implications for narcissism, cardiovascular disease risk, and a variety of psychiatric disorders.

Purpose: We aimed to analyze regional variations in the assignment of (ICD-10) codes to acute respiratory infections, seeking to identify notable anomalies that suggest diverse diagnoses of the same condition.
Methods: We analyzed national weekly diagnosis data for acute respiratory infections (ICD-10 codes J00-J22) in Poland from 2010 to 2019, covering all 380 county-equivalent administrative regions and encompassing 292 million consultations. Data were aggregated into age brackets.
Considering the numerous concerns patients express about having implantable cardioverter-defibrillators (ICDs) and the potential clinical implications of these concerns, it is essential to develop a valid and reliable measure of ICD-related concerns. The implantable cardioverter-defibrillator concerns (ICDC) questionnaire was initially designed for ICD recipients in England to assess and address these concerns. However, it remains uncertain whether this questionnaire possesses similar measurement properties and is suitable for ICD recipients in the United States.

Background: Lactate dehydrogenase (LDH) is a critical enzyme widely used in clinical diagnostics. However, variations in measurement systems can lead to inconsistent results, potentially impacting clinical decision-making. This study aimed to evaluate the comparability of lactate dehydrogenase measurements by comparing routine methods with the IFCC reference method, and to analyze the standardization status of LDH testing through external quality assessment (EQA).

Although sulfur-bearing minerals are valuable resources, they pose significant environmental risks to river ecosystems by releasing hazardous leachate. Accurately tracing these sources is crucial but challenging due to overlapping chemical signatures and pollutant transport dynamics in river systems. This study investigates seasonal and spatial variations in sulfate (SO) and trace element contributions in mining districts of the upper Nakdong River basin, South Korea.
