Multicenter Study
Dynamics of obesity paradox after stroke, related to time from onset, age, and causes of death.
Paradoxical longevity in obese patients with established disease has been documented in various conditions. We aimed to find whether such a relationship exists in ischemic stroke patients, with stratified analyses according to time of death after stroke, age, and cause of death. ⋯ Our results documented obesity paradox in stroke survivors, regardless of age and causes of death, and it became evident a sufficient time after stroke onset.

Acute cerebral infarction may coexist with hypertensive intracerebral hemorrhage (ICH) because lacunae and hypertensive ICH share common risk factors and small-vessel pathology. We sought to determine the frequency and predictors of new ischemic lesions (NIL) on diffusion-weighted imaging (DWI), in patients with acute hypertensive ICH, and to investigate whether NIL predicts subsequent clinical cerebrovascular events. ⋯ NILs frequently occur during the acute phase of ICH and are mainly associated with small-vessel pathogenesis. NILs occurring together with ICH may be a useful marker to identify patients at high risk of future clinical cerebrovascular events or vascular death.

To assess the frequency and phenotype of hexanucleotide repeat expansions in C9ORF72 in a large cohort of patients of Dutch descent with familial (fALS) and sporadic (sALS) amyotrophic lateral sclerosis (ALS), progressive muscular atrophy (PMA), and primary lateral sclerosis (PLS). ⋯ The hexanucleotide repeat expansion in C9ORF72 is a major cause of fALS and apparently sporadic ALS in the Netherlands. Patients who carry the repeat expansion have an earlier onset, shorter survival, and familial aggregation of dementia. These results challenge the classic definition of fALS and may justify genetic testing in patients with sALS.

Approximately one-third of refugees worldwide live in refugee camps. Selected neurologic diseases are actively reported in some refugee camps. ⋯ Targeted programs addressing epilepsy and stroke among refugees in camps should become a priority and indicate that other chronic neurologic diseases that may be under- or misdiagnosed may also be common in refugee camps. Given that significant under-reporting is likely, our findings demonstrate the pressing need for coordinated preventive and interventional measures for epilepsy and stroke in refugee camps.
