Background And Objectives: To investigate CSF findings in relation to clinical and electrodiagnostic subtypes, severity, and outcome of Guillain-Barré syndrome (GBS) based on 1,500 patients in the International GBS Outcome Study.
Methods: Albuminocytologic dissociation (ACD) was defined as an increased protein level (>0.45 g/L) in the absence of elevated white cell count (<50 cells/μL).
Background And Objectives: Infections play a key role in the development of Guillain-Barré syndrome (GBS) and have been associated with specific clinical features and disease severity. The clinical variation of GBS across geographical regions has been suggested to be related to differences in the distribution of preceding infections, but this has not been studied on a large scale.
Methods: We analyzed the first 1,000 patients included in the International GBS Outcome Study with available biosamples (n = 768) for the presence of a recent infection with , hepatitis E virus, , cytomegalovirus, and Epstein-Barr virus.
Article Synopsis
- The study looked at a score called mEGOS that helps predict if people with a sickness called Guillain-Barré syndrome (GBS) will be able to walk on their own or not.
- Researchers used information from 1,500 patients from a big study to see if mEGOS worked well for people from different regions and made some improvements to it.
- The updated score showed good results in different areas, but some places had better or worse outcomes than expected, and they found that things like age and how weak someone’s limbs were were important for predicting problems.
Pollinators serve critical roles for the functioning of terrestrial ecosystems, and have an estimated annual value of over $150 billion for global agriculture. Mounting evidence from agricultural systems reveals that pollinators are declining in many regions of the world, and with a lack of information on whether pollinator communities in natural systems are following similar trends, identifying factors which support pollinator visitation and services are important for ameliorating the effects of the current global pollinator crisis. We investigated how fire affects resource structure and how that variation influences floral pollinator communities by comparing burn versus control treatments in a southeastern USA old-field system.

Objective: Titin gene (TTN) mutations have been described in eight families with hereditary myopathy with early respiratory failure (HMERF). Some of the original patients had features resembling myofibrillar myopathy (MFM), arguing that TTN mutations could be a much more common cause of inherited muscle disease, especially in presence of early respiratory involvement.
Methods: We studied 127 undiagnosed patients with clinical presentation compatible with MFM.
The Chronic Dysimmune neuropathies (CDN) are a clinically heterogeneous group of polyneuropathies united by their presumed immune mediated aetiology. At present such neuropathies are classified as Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), Multifocal Motor Neuropathy (MMN) and the Neuropathies in association with serum Paraproteins (Paraproteinaemic Neuropathies). This classification fails to recognise other distinctive syndromes and is limited by heterogeneity within, and overlap between, subgroups.
