A hot-Jupiter progenitor on a super-eccentric retrograde orbit.

Giant exoplanets orbiting close to their host stars are unlikely to have formed in their present configurations. These 'hot Jupiter' planets are instead thought to have migrated inward from beyond the ice line and several viable migration channels have been proposed, including eccentricity excitation through angular-momentum exchange with a third body followed by tidally driven orbital circularization. The discovery of the extremely eccentric (e = 0.

Efficacy of a family intervention program for prevention of hospitalization in patients with schizophrenia. A naturalistic multicenter controlled and randomized study in Spain.

Background: According to most relevant guidelines, family psycho-educational interventions are considered to be one the most effective psychosocial treatments for people with schizophrenia. The main outcome measure in controlled and randomized studies has been prevention of relapses and admissions, and encouragement of compliance, although some questions remain about its applicability and results in clinical practice.

Objectives: The aim of study was to evaluate the efficacy and implementation of a single family psychoeducational intervention in 'real' conditions for people diagnosed with schizophrenia.

Diagnosis of acute leukemia in cerebrospinal fluid (CSF-acute leukemia).

Cerebrospinal fluid-acute leukemia (CSF-acute leukemia) is a frequent and serious complication in patients with acute leukemia. One of the major problems of this complication is the diagnosis process itself. CSF cytology is currently considered the gold standard for establishing the diagnosis, a technique which presents various processing limitations, seriously impacting the predictive values.

Neurocysticercosis: radiologic-pathologic correlation.

Neurocysticercosis is a neurologic parasitic disease caused by the encysted larva of the tapeworm Taenia solium and is the most important parasitic disease of the human central nervous system. It is the most common cause of acquired epilepsy in endemic settings and constitutes a public health challenge for most of the developing world. Nowadays, however, as a result of globalization, neurocysticercosis is being seen more frequently in developed countries as well.

Predictive factors for intracerebral hemorrhage in patients with cavernous angiomas.

Objectives: Prediction of intracerebral hemorrhage (ICH) in patients with cavernous angiomas is not totally elucidated. The aims of our study were to determine the rate of cerebral hemorrhage, its associated factors, and the clinical outcome in patients with cavernous angiomas in a Hispanic population.

Methods: We studied 133 patients with cavernous angiomas.

Prospective study of single and multiple lacunar infarcts using magnetic resonance imaging: risk factors, recurrence, and outcome in 175 consecutive cases.

Background And Purpose: We investigated whether lacunar infarct (LI) patients with >1 lacune have different vascular risk factors, a different prognosis, and poorer functional outcome than those with a single lacune.

Methods: The study included 175 first-ever LI patients. The group was divided according to the presence of multiple (n=136) or single (n=39) LI.
