Key takeaway

• Acute atrial fibrillation (AF) is an independent predictor of severity of neurological deficits from early acute ischemic stroke and a high-probability predictor of death within 30 days after such strokes.

Why this matters

• A comprehensive understanding of the relationship between acute AF and risk for acute ischemic stroke and prognosis will help improve management and treatment of patients with acute ischemic stroke.

Study design

• The retrospective study included patients with acute ischemic stroke within the prior 24 hours; 12-lead electrocardiogram in the emergency department; and hospitalization and treatment at the hospital stroke center.
• The cohort of 706 patients admitted to a single center in Shanghai, China, from December 2019 to December 2021, included 142 with episodes of acute AF and 564 without such episodes.
• Patients with acute ischemic stroke and acute AF – including AF of new onset, paroxysmal, persistent, or permanent with symptoms such as palpitations or dizziness attributed to rapid ventricular rates – were identified.
• Neurological deficits were assessed using the 7-day National Institutes of Health Stroke Scale/Score (NIHSS). Patients with a 7-day NIHSS score of at least 16 were considered to have moderate to severe stroke.
• Associations between acute AF onset and the severity of early neurological deficits were assessed and related to all-cause mortality within 30 days of the stroke.

Key results

• Patients with acute AF were older than those without acute AF (80.3 years vs. 71.0 years; P < .001).
• Baseline NIHSS scores averaged 16.09 for the stroke patients with acute AF and 8.65 for those without acute AF (P < .001).
• Significantly more patients with acute AF than without acute AF had a 7-day NIHSS score of at least 16 (45.1% vs. 14.4%; P < .001).
• More patients with than without acute AF underwent transcatheter thrombectomy (44.4% vs. 24.5%; P < .001) or received thrombolytic therapy (31.6% vs. 19.7%; P = .005).
• Patients aged 73 years or older showed baseline NIHSS score and acute AF as independent risk factors for early neurological deficits in stroke patients admitted to the emergency department.
• Mortality at 30 days was significantly higher in patients with acute AF than in those without acute AF (30.3% vs. 10.1%; P < .001).
• Baseline NIHSS had an adjusted odds ratio for 30-day mortality of 1.18 (95% confidence interval, 1.15-1.22; P < .001).  
• Other independent predictors included acute AF (1.87 [95% CI, 1.09-3.19; P = .022]) and age 73 or older (2.00 [95% CI, 1.18-3.37; P = .01]).

Limitations

• The study was retrospective and didn’t have access to some potentially relevant data, such as duration of AF.
• The single-center study with limited generalizability does not necessarily represent the broad population of stroke patients in China or elsewhere.

Disclosures

• This study was supported by the Cardiovascular Multidisciplinary Integrated Research Fund and Construction of Shanghai Municipal Health Commission.
• The authors report no relevant financial relationships.

Key takeaway

• High-dose furosemide after cardiac surgery is associated with increased mortality and other adverse outcomes.

Why this matters

• The influence of furosemide on prognosis after cardiac surgery is not fully understood.
• The current findings suggest that high-dose furosemide after cardiac surgery is associated with increased risk for death and other adverse events and therefore should be used cautiously in that setting.

Study design

• The retrospective cohort of 6,752 cardiac surgery patients was divided into two groups according to average daily furosemide dosage after cardiac surgery: less than 20 mg (low-dose group, n = 6,033) and at least 20 mg (high-dose group, n = 719).
• The group were compared for total furosemide dose, total furosemide dose of at least 200 mg, total dose of furosemide by patient weight, and average daily furosemide dose of at least 20 mg.
• The primary outcomes were in-hospital mortality and mortality at 1 year after cardiac surgery. Secondary outcomes were length of hospital stay of at least 14 days, length of ICU stay of at least 3 days, and mechanical ventilation for at least 48 hours.
• The study excluded patients aged younger than 18 whose weight data was missing or who had more than 5% of their data missing.

Key results

• Patients in the high-dose furosemide group tended to be older and have a higher body mass index (BMI) and higher rates of diabetes, chronic pulmonary diseases, heart failure, renal failure, blood transfusion, vasopressor use, and valvular surgery.
• They also tended have higher white cell counts and higher levels of blood urea nitrogen, creatinine, glucose, and lactate.
• Those in the high-dose group also were on vasopressors and ventilatory support longer.
• In adjusted multivariate analysis, increased in-hospital mortality was associated with average daily furosemide dose, average daily dose of at least 20 mg/d, and total dose of at least 200 mg.
• Increased mortality at 1 year was associated with total furosemide dose and average daily furosemide dose.
• Significant multivariate predictors of hospital stay of at least 14 days, length of ICU stay of at least 3 days, and mechanical ventilation for at least 48 hours after cardiac surgery included total furosemide dose, total dose by weight, average daily furosemide dose of at least 20 mg/d, and total dose of at least 200 mg.
• In subgroup analyses, average daily furosemide dose of at least 20 mg/d significantly increased risk for in-hospital mortality among patients younger than 60 years or with BMI of at least 28 who received vasopressors or blood transfusions, those with renal failure, and those with heart failure not involving congestion.

Limitations

• No limitations were discussed.

Disclosures

• The study was supported by grants from the National Natural Science Foundation of China, China Postdoctoral Science Foundation, and Jiangsu Postdoctoral Science Foundation.
• The authors declared that they have no competing interests.

Key takeaway

Maladaptive schemas (entitlement, vulnerability, and emotional deprivation) and cognitive evaluation systems (self-esteem and systemizing-empathizing) are associated with grandiose and vulnerable narcissism.

Why this matters

The cognitive features and phenotypic diversity of narcissism subtypes are partially unknown.

This study integrates both grandiose and vulnerable narcissism into a common framework with cognitive components connected to these traits.
 

Study design

This study enrolled 478 participants (397 female and 4 did not reveal their gender).

The average age of participants was 35 years (standard deviation, 14.97), with a range of 18-76 years.

A 25-item version of the Narcissistic Personality Inventory (NPI), a 40-item self-report measure of narcissism traits, was used to assess the level of authority, grandiose exhibitionism, and entitlement/exploitativeness characteristics of study participants.

The Maladaptive Covert Narcissism Scale, an expanded version of the 23-item self-report Hypersensitive Narcissism Scale, was used to assess the level of hypersensitivity, vulnerability, and entitlement of study participants.

The Rosenberg Self-Esteem Scale, a 10-item self-report scale, was used to assess the level of self-esteem of study participants.

The Young Schema Questionnaire is a 244-item measure of 19 different maladaptive schemas and was used to observe Emotional Deprivation, Vulnerability to Harm and Illness, and Entitlement schemas of study participants.

The Empathizing Quotient is a self-report measure and was used to assess the emotional intelligence of study participants.
 

Key results

Moderate correlation between grandiose and vulnerable narcissism and the Entitlement schema was observed.

A moderate/strong connection was observed between vulnerable narcissism and the Vulnerability to Harm and Illness schema and a moderate connection with the Emotional Deprivation schema.

No significant correlation was observed between grandiose narcissism and the Emotional Deprivation schema.

A moderate, negative correlation between vulnerable narcissism and emotional skills was observed.

A positive, weak connection between grandiose narcissism and self-esteem; and a negative, moderate connection between vulnerable narcissism and self-esteem were observed.

Gender and age were associated with empathic skills, and age was weakly/moderately connected with self-esteem and vulnerable narcissism.
 

Limitations

This was a cross-sectional analysis investigating a temporally specific state of personality and cognitive functioning.

The gender ratio was shifted toward women in this study.

Conclusions drawn from connections between observed components are interchangeable and cause/effect connections cannot be discerned.
 

Disclosures

The study was supported by the National Research, Development, and Innovation Office (Grant No. NRDI–138040) and by the Human Resource Development Operational Program – Comprehensive developments at the University of Pécs for the implementation of intelligent specialization (EFOP-3.6.1-16-2016-00004).
