Diagnostic Value of Computed Tomography Angiography in Suspected Acute Ischemic Stroke Patients With Respect to National Institutes of Health Stroke Scale Score.

Objective: Noncontrast computed tomography (NCCT) plus computed tomography angiography (CTA) is the standard imaging modality for acute stroke. We investigated whether there is an additional diagnostic value of supra-aortic CTA in relation to National Institutes of Health Stroke Scale (NIHSS) and resultant effective radiation dose.

Methods: In this observational study, 788 patients with suspected acute stroke were included and divided into 3 NIHSS groups: group 1, NIHSS 0-2; group 2, NIHSS 3-5; and group 3, NIHSS ≥ 6.

Post-COVID-19 bifacial weakness and paraesthesia: a case report.

Objectives: We present a patient with bifacial weakness and paraesthesia subtype of Guillain-Barré syndrome (GBS), which occurred 1 month after a SARS-CoV-2 infection. While GBS as complication of SARS-CoV-2 infection has been described many times, only a few cases of post-COVID-19 bifacial weakness and paraesthesia are known to date.

Results: A 59-year-old man presented with thoracoradicular pain, paraesthesias of hands and feet, as well as progressive bilateral facial palsy.

Fitness response variation within and among consumer species can be co-mediated by food quantity and biochemical quality.

In natural heterogeneous environments, the fitness of animals is strongly influenced by the availability and composition of food. Food quantity and biochemical quality constraints may affect individual traits of consumers differently, mediating fitness response variation within and among species. Using a multifactorial experimental approach, we assessed population growth rate, fecundity, and survival of six strains of the two closely related freshwater rotifer species Brachionus calyciflorus sensu stricto and Brachionus fernandoi.

Isolation and antimicrobial susceptibility of Streptococcus castoreus isolated from carcasses of European beavers (Castor fiber) in Germany.

Streptococcus (S.) castoreus was isolated from seven beavers (Castor fiber), which were found dead in the federal state of Brandenburg, Germany, and submitted to the Berlin-Brandenburg State laboratory for post mortem diagnostics. The isolates originated from various inflammatory processes where they were associated with other Gram negative and Gram positive aerobic and/or anaerobic bacteria (i.

The genetic legacy of multiple beaver reintroductions in Central Europe.

The comeback of the Eurasian beaver (Castor fiber) throughout western and central Europe is considered a major conservation success. Traditionally, several subspecies are recognised by morphology and mitochondrial haplotype, each linked to a relict population. During various reintroduction programs in the 20th century, beavers from multiple source localities were released and now form viable populations.
