Background: There is a widespread belief that Asians are more susceptible to hemorrhagic transformation (HT) after receiving recombinant tissue-type plasminogen activator (rt-PA) for acute ischemic stroke (AIS). However, this has not been examined in clinical practice. This study aims to compare the incidence of symptomatic hemorrhagic transformation (SHT) among thrombolysis-treated AIS patients in China and in the United States.
Methods: We compared 212 consecutive patients receiving thrombolysis within 4.5 hours of onset ± endovascular therapy from an American (n = 86) and a Chinese Stroke Center (n = 126). SHT was defined using various definitions based on the National Institute for Neurological Disorders and Stroke Recombinant Tissue Plasminogen Activator (NINDS rt-PA) trials, European-Australian Cooperative Acute Stroke Study 2 (ECASS2), and a modified version of Safe Implementation of Thrombolysis in Stroke-Monitoring Study (mSITS-MOST) study criteria. We used Firth logistic regression to adjust for confounding variables and to identify potential predictors.
Results: American patients were older, and had higher prevalence of diabetes, hypertension, cardiac disease, and prestroke use of antithrombotics. They also had higher baseline serum glucose, shorter onset-to-treatment time, and fewer endovascular treatments. The rates of SHT were higher in the American cohort compared to the Chinese cohort: 18.6% versus 14.3% based on NINDS definition of SHT; 15.1% versus 12.7% based on ECASS2; and 11.6% versus 7.2% based on mSITS-MOST. However, none of these differences were significant (unadjusted and adjusted P values > .05). Fatal HT was comparable in Americans versus Chinese (8.1% versus 8.7%). Serum glucose emerged as an independent predictor of SHT (P = .024).
Conclusions: In our cohorts, the rate of SHT after thrombolysis is equivalent between Chinese and North American stroke patients.

Background: Post-stroke epilepsy (PSE) is a major complication of stroke. However, data about the predictors of PSE in patients with acute ischemic stroke (AIS) undergoing mechanical thrombectomy are limited.
Objective: To evaluate the relationship between intraoperative angiographic signs and PSE risk in patients with anterior circulation AIS who underwent mechanical thrombectomy.

Arterial stiffness is a well-known risk factor for cardiovascular disease. Although estradiol (E2) is known to be cardioprotective, the available data point to a growing cardiovascular disease risk in women before menopause due to post-traumatic stress disorder (PTSD). The present study aimed to investigate the effects of E2 on arterial compliance in trauma-exposed premenopausal women, with and without a clinical diagnosis PTSD.

Introduction And Importance: Retiform hemangioendothelioma(RH) is a rare vascular tumor affecting patients over a wide age range without a gender predilection; only about 50 cases have been described so far.
Case Presentation: We report a case of submandibular retiform hemangioendothelioma in a 58-year-old woman who had been diagnosed with RH 20 years ago and had experienced recurrence four times during the past 20 years. This will increase the limited number of such cases in the hope of gaining a better understanding of this rare type of tumor.

Introduction: Haemodynamic atrioventricular delay (AVD) optimisation has primarily focussed on signals that are not easy to acquire from a pacing system itself, such as invasive left ventricular catheterisation or arterial blood pressure (ABP). In this study, standard clinical central venous pressure (CVP) signals are tested as a potential alternative.
Methods: Sixteen patients with a temporary pacemaker after cardiac surgery were studied.

The body weight-based thrombolytic medication strategy in clinical trials shows critical defects in recanalization rate and post-thrombolysis hemorrhage. Methods for perceiving thrombi heterogeneity of thrombolysis resistance is urgently needed for precise thrombolysis. Here, we revealed the relationship between the thrombin heterogeneity and the thrombolysis resistance in thrombi and created an artificial biomarker-based nano-patrol system with robotic functional logic to perceive and report the thrombolysis resistance of thrombi.
