We describe the resource availability and diet of western lowland gorillas (Gorilla gorilla gorilla) from a new study site in the Central African Republic and Republic of Congo based on 3 years of study. The results, based on 715 fecal samples and 617 days of feeding trails, were similar to those reported from three other sites, in spite of differences in(More)
BACKGROUND AND PURPOSE Many studies associate fever with poor outcome in patients with neurological injury, but this relationship is blurred by divergence in populations and outcome measures. We sought to incorporate all recent scholarship addressing fever in brain-injured patients into a comprehensive meta-analysis to evaluate disparate clinical findings.(More)
The ascending reticular activating system (ARAS) mediates arousal, an essential component of human consciousness. Lesions of the ARAS cause coma, the most severe disorder of consciousness. Because of current methodological limitations, including of postmortem tissue analysis, the neuroanatomic connectivity of the human ARAS is poorly understood. We applied(More)
BACKGROUND AND PURPOSE There are uncertainties surrounding the optimal management of patients with brain swelling after an ischemic stroke. Guidelines are needed on how to manage this major complication, how to provide the best comprehensive neurological and medical care, and how to best inform families facing complex decisions on surgical intervention in(More)
BACKGROUND AND PURPOSE Despite the abundance of emerging multimodal imaging techniques in the field of stroke, there is a paucity of data demonstrating a strong correlation between imaging findings and clinical outcome. This study explored how proximal arterial occlusions alter flow in collateral vessels and whether occlusion or extent of collaterals(More)
PURPOSE To examine whether the severity and spatial distribution of reductions in apparent diffusion coefficient (ADC) are associated with clinical outcomes in patients who become comatose after cardiac arrest. MATERIALS AND METHODS This was an institutional review board-approved, HIPAA-compliant retrospective study of 80 comatose patients with cardiac(More)
BACKGROUND Aphasia is a disabling chronic stroke symptom, but the prognosis for patients presenting with aphasia in the hyperacute window has not been well characterized. The purpose of this study is to assess the prognosis for recovery of language function in subjects presenting with aphasia caused by ischemic stroke within 12 hours of symptom onset. (More)
OBJECTIVE To build new algorithms for prognostication of comatose cardiac arrest patients using clinical examination, and investigate whether therapeutic hypothermia influences the value of the clinical examination. METHODS From 2000 to 2007, 500 consecutive patients in non-traumatic coma were prospectively enrolled, 200 of whom were post-cardiac arrest.(More)
Hypoxic-ischemic brain injury is a well known consequence of cardiac arrest. Variable injuries can occur with purely hypoxic or histotoxic insults such as asphyxiation and carbon monoxide poisoning. The injury may happen at the time of the insult, but there may also be continued damage after circulation and oxygenation are reestablished. The nature and(More)
We examined the influence of ecological (diet, swamp use, and rainfall) and social (intergroup interaction rate) factors on ranging behavior in one group of western gorillas (Gorilla gorilla gorilla) during a 16-month study. Relative to mountain gorillas, western gorillas live in habitats with reduced herb densities, more readily available fruit (from(More)
