Clinical profile, risk factors and aetiology of young ischaemic stroke patients in Asia: A prospective, multicentre, observational, hospital-based study in eight cities

Background and Objective: There is a lack of international collaborative studies on young adults with ischaemic stroke in Asia. The aim of this study was to investigate risk factors, aetiology and outcome at hospital discharge of these patients across 8 participating countries in Asia. Methods: This was a prospective, observational, multicentre, hospital based cohort study. Consecutive young stroke patients with confirmed cerebral infarction between the ages of 18-49 were recruited from December 2011 to May 2012. Data was collected for patient demography, risk factors, investigations, clinical profile and TOAST classification. Outcome measures were death and independence (modified Rankin score≤ 2) at hospital discharge. Results: Two hundred and eighteen patients with the mean age was 40.8±6.7 years were recruited. There was a larger proportion of male patients with a ratio of 1.9:1. Traditional risk factors observed were hypertension (n=103; 47.3%), dyslipidaemia (n=93; 42.4%), smoking (n=85; 38.8%), diabetes (n=53; 24.3%), alcohol use (n=33; 15.0%), a previous history of stroke and transient ischaemic attacks (6.4%), family history (n=12; 5.5%), migraine (n=6;2.8%), pregnancy related (n=5; 2.3%) and numerous cardiac risk factors (0.9-5.5%). The majority suffered arterial infarction; n=216 (99.4%) while n=2 (0.6%) had venous strokes. The predominant stroke subtypes were large artery atherosclerosis (LAA); 29.8% and small vessel occlusion (SVO); 20.2%. LAA and SVO accounted for 37.5% of all stroke subtypes in the ≤36 year age-group. Cardioembolism (15.1%) and stroke of determined aetiology (14.7%) contributed to the other categories of identified stroke subtypes. Mortality on hospital discharge was 3.1% while 65.1% of patients were independent on discharge. Conclusion: This study demonstrated the substantial presence of premature atherosclerosis and conventional risk factors in young ischaemic stroke patients from 8 Asian cities. Venous infarction from cerebral venous thrombosis was rare in this study. Outcome on hospital discharge was poorer compared to Western studies. Detection of vascular risk factors and primary prevention measures should be initiated during late adolescence or early adulthood in urban Asia.

Experiences of living with myasthenia gravis: a qualitative study with Taiwanese people.

Myasthenia gravis (MG) is an auto-immune, neuromuscular disorder, which presents with symptoms of fluctuating muscle fatigue because of a dysfunction of the neuromuscular junction. This study explores the illness experience of patients with MG, their experiences of illness, its challenges, and their coping and support strategies. In-depth interviews were undertaken with nine participants with MG (six for a generalized type of MG, three for ocular type). Data were subjected to inductive content and thematic analysis. Four themes emerged from MG patients with associated subthemes. They were "perceptions of MG," "challenges of MG, "social support," and "adapting and adjusting to MG." The study reveals the way in which individuals respond to and cope with their diagnosis. The importance of social and peer support is a key factor as well as the development of psychological strategies to live with MG. The recognition that there was a need to recognize the role of Western medicine in controlling their disease was also an important finding.

Complication of acute stroke: A study in ten Asian countries

Background and Objective: There is a paucity of studies looking into the frequency of complications after stroke among Asians. We sought to determine the frequency and rate of complications among Asians after acute stroke. Methods: Consecutive patients with acute stroke among 10 participating Asian countries were included in the study. The frequency and timing of pre-determined complications, and their relation to area of admission were noted. Results: Of the 1,153 patients included in the study, 423 (41.9%) developed complications within the first 2 weeks of stroke. Recurrent stroke, chest infections and urinary tract infections were most commonly encountered, and were most frequent within the first week of stroke onset. A lower rate of complications was noted among patients admitted at an organized stroke unit. Conclusion: There is a similar rate of frequency and timing of complications after acute stroke among Asians as compared with other populations.
