While circulating levels of soluble Intercellular Adhesion Molecule 1 (sICAM-1) have been associated with diverse conditions including myocardial infarction, stroke, malaria, and diabetes, comprehensive analysis of the common genetic determinants of sICAM-1 is not available. In a genome-wide association study conducted among 6,578 participants in the Women's Genome Health Study, we find that three SNPs at the ICAM1 (19p13.2) locus (rs1799969, rs5498 and rs281437) are non-redundantly associated with plasma sICAM-1 concentrations at a genome-wide significance level (P<5x10(-8)), thus extending prior results from linkage and candidate gene studies. We also find that a single SNP (rs507666, P = 5.1x10(-29)) at the ABO (9q34.2) locus is highly correlated with sICAM-1 concentrations. The novel association at the ABO locus provides evidence for a previously unknown regulatory role of histo-blood group antigens in inflammatory adhesion processes.

Stroke is a leading cause of morbidity and mortality worldwide, and it is likely to worsen in developing countries over the next two decades based on the projections by the World Health Organization (WHO). With the current scourge of HIV/AIDS and the battle against other communicable diseases like multi-drug resistant malaria and tuberculosis; Nigeria, the most populous black nation in the world, stands to risk the further straining of its resources as a result of the increasing prevalence of stroke and other cardiovascular diseases due to epidemiological transition. The current prevalence of stroke in Nigeria is 1.14 per 1000 while the 30-day case fatality rate is as high as 40%. Management of the disease is largely conservative while there is little or no funding for high-quality research. Primary prevention is the key to reducing the burden of the disease in a country with such poor resources.

Glycogen synthase kinase-3, a serine/threonine kinase, has been implicated in a wide variety of pathological conditions such as diabetes, Alzheimer's disease, stroke, bipolar disorder, malaria and cancer. Herein we report 3D-QSAR analyses using CoMFA and CoMSIA and molecular docking studies on 3-anilino-4-phenylmaleimides as GSK-3alpha inhibitors, in order to better understand the mechanism of action and structure-activity relationship of these compounds. Comparison of the active site residues of GSK-3alpha and GSK-3beta isoforms shows that all the key amino acids involved in polar interactions with the maleimides for the beta isoform are the same in the alpha isoform, except that Asp133 in the beta isoform is replaced by Glu196 in the alpha isoform. We prepared a homology model for GSK-3alpha, and showed that the change from Asp to Glu should not affect maleimide binding significantly. Docking studies revealed the binding poses of three subclasses of these ligands, namely anilino, N-methylanilino and indoline derivatives, within the active site of the beta isoform, and helped to explain the difference in their inhibitory activity.

Most seizures during pregnancy occur in women who already have epilepsy. During pregnancy most women will continue their previous level of seizure control, although 15-30% may experience an increase in seizures. Pregnancy-induced changes in antiepileptic drug pharmacokinetics are a major factor affecting changes in seizure control during pregnancy, although compliance is also a significant factor. Status epilepticus occurs in only 1-2% of pregnancies, and if treated appropriately and aggressively carries a fairly low risk of morbidity and mortality. Structural and metabolic changes may precipitate new-onset seizures during pregnancy. The structural causes include intracranial hemorrhage of multiple types, cerebral venous sinus thrombosis, and ischemic stroke. Metabolic causes include hyperemesis gravidarum; acute hepatitis (due to fatty liver of pregnancy or viral hepatitis); metabolic diseases, such as acute intermittent porphyria; infections, such as malaria; and eclampsia.

Cerebral malaria is a complication of Plasmodium falciparum malaria and can result in various neurological manifestations. We report a rare case of cerebral malaria with vertebrobasilar stroke, presenting predominantly with signs of lateral medullary and cerebellar infarctions. We suggest that, in patients presenting with fever and a concurrent vertebrobasilar stroke, the possibility of cerebral malaria should also be considered.

The aim of this study was to describe and analyse hospital mortality patterns after the Liberian war. Data were collected retrospectively from January to July 2005 in a referral hospital in Monrovia, Liberia. The overall fatality rate was 17.2% (438/2543) of medical admissions. One-third of deaths occurred in the first 24h. The adult fatality rate was 23.3% (241/1034). Non-infectious diseases accounted for 56% of the adult deaths. The main causes of death were meningitis (16%), stroke (14%) and heart failure (10%). Associated fatality rates were 48%, 54% and 31% respectively. The paediatric fatality rate was 13.1% (197/1509). Infectious diseases caused 66% of paediatric deaths. In infants <1 month old, the fatality rate was 18% and main causes of death were neonatal sepsis (47%), respiratory distress (24%) and prematurity (18%). The main causes of death in infants > or =1 month old were respiratory infections (27%), malaria (23%) and severe malnutrition (16%). Associated fatality rates were 12%, 10% and 19%. Fatality rates were similar to those found in other sub-Saharan countries without a previous conflict. Early deaths could decrease through recognition and early referral of severe cases from health centres to the hospital and through assessment and priority treatment of these patients at arrival.

Homozygous, sickle-cell disease (SCD) is responsible for acute complication, especially anaemic crisis and special situation such as acute chest syndrome, stroke and acute priapism. Pregnancy sickle-cell disease presents high risk for the mother and the fetus. In these indications, blood transfusion is the main therapy aiming to reduce anaemia in order to restore hemoglobin's rate or to increase normal Hb proportion. This study aims to assess the short-term efficiency of the red cell transfusion in SCD homozygous form. One hundred and twelve homozygous sickle-cell patients were enrolled in this prospective study: 59 females and 53 males, median age is 21,8 years (extremes: 2 and 45 years). These patients are mostly with very low income. Two groups of patients are included in this study. In the first group, patients present acute anemia crisis caused by infections disease (malaria, bacterial infections). In the second group (20 cases), SCD patients have particularly situations: pregnancy (10 cases); stroke (six cases); cardiac failure (two cases) and priapism (two cases). Transfusion treatment in first group is simple regimen. Transfusion of EC increased median Hb level at 2,9 g/dl (extremes: 1,1 and 4,7). In the second group of patients, 16 cases were transfused by manual partial exchange (1-3) and four patients received simple regimen of transfusion. Median Hb level was 3,1g/dl (extremes: 2,4-4,9 g/dl). HbS percentage reduction was after PTE between -30 and -66,8% (median: -52,6%). According to our diagnostic possibilities (blood serologic test), we have not found any contamination by HIV, HBV and HCV (virus).

There is paucity of data evaluating intracranial pressure (ICP) rise and its management in acute viral encephalitis (AVE). Noteworthy is the current prevalence of unselective and broad utilization of ICP lowering therapies in clinical practice. Trends in current management of ICP in AVE emanate from data extrapolated from results of studies done on cerebral malaria, bacterial meningitis, stroke, and brain trauma patients. In this article we review (1) clinical correlates of raised ICP, (2) pathology, (3) imaging data, (4) monitoring, and, (5) treatment, of raised ICP in AVE. ICP monitoring is a useful adjunct to management of raised ICP in adults, becoming especially important in Herpes encephalitis and encephalitis with status epilepticus. In children it substantially influences clinical management and continuous monitoring of mean blood pressure (MBP) and ICP can aid in early diagnosis and treatment when cerebral perfusion pressure (CPP) falls below critical levels. Current evidence suggests that the pathomechanisms that contribute to the development of raised intracranial pressure vary in viral encephalitides of different etiology, and different forms of cerebral edema result at different times in the course of the illness, thus creating a need for studies to investigate the usefulness of various edema-specific ICP lowering modalities in AVE.

Sickle cell trait occurs in approximately 300 million people worldwide, with the highest prevalence of approximately 30% to 40% in sub-Saharan Africa. Long considered a benign carrier state with relative protection against severe malaria, sickle cell trait occasionally can be associated with significant morbidity and mortality. Sickle cell trait is exclusively associated with rare but often fatal renal medullary cancer. Current cumulative evidence is convincing for associations with hematuria, renal papillary necrosis, hyposthenuria, splenic infarction, exertional rhabdomyolysis, and exercise-related sudden death. Sickle cell trait is probably associated with complicated hyphema, venous thromboembolic events, fetal loss, neonatal deaths, and preeclampsia, and possibly associated with acute chest syndrome, asymptomatic bacteriuria, and anemia in pregnancy. There is insufficient evidence to suggest an independent association with retinopathy, cholelithiasis, priapism, leg ulcers, liver necrosis, avascular necrosis of the femoral head, and stroke. Despite these associations, the average life span of individuals with sickle cell trait is similar to that of the general population. Nonetheless, given the large number of people with sickle cell trait, it is important that physicians be aware of these associations.

Controversy and activism have long been linked to the subject of primate research. Even in the midst of raging ethical debates surrounding fertility treatments, genetically modified foods and stem-cell research, there has been no reduction in the campaigns of activists worldwide. Playing their trade of intimidation aimed at ending biomedical experimentation in all animals, they have succeeded in creating an environment where research institutions, often painted as guilty until proven innocent, have avoided addressing the issue for fear of becoming targets. One area of intense debate is the use of primates in stroke research. Despite the fact that stroke kills more people each year than AIDS and malaria, and less than 5% of patients are candidates for current therapies, there is significant opposition to primate stroke research. A balanced examination of the ethics of primate stroke research is thus of broad interest to all areas of biomedical research.
