[Acute undifferentiated febrile illness among outpatients: differential diagnosis between dengue, zika, Argentine hemorrhagic fever and COVID-19].

The "acute undifferentiated febrile illness" (AUFI) encompasses a range of diseases characterized by the presence of fever, often prompting consultations in emergency services. During epidemics like COVID-19 or dengue, a surge in consultations occurs, resulting in long wait times for patients. Errors in first diagnosis can result in severe consequences.

Oscillatory Brain Activity in the Canonical Alpha-Band Conceals Distinct Mechanisms in Attention.

Brain oscillations in the alpha-band (8-14 Hz) have been linked to specific processes in attention and perception. In particular, decreases in posterior alpha-amplitude are thought to reflect activation of perceptually relevant brain areas for target engagement, while alpha-amplitude increases have been associated with inhibition for distractor suppression. Traditionally, these alpha-changes have been viewed as two facets of the same process.

Benralizumab in Severe Eosinophilic Asthma and Chronic Rhinosinusitis with Nasal Polyps: The Real-World, Multi-Country RANS Observational Study.

Purpose: Real-world evidence of benralizumab effectiveness on nasal polyps (NP) and asthma outcomes in patients with severe eosinophilic asthma (SEA) and comorbid chronic rhinosinusitis with NP are limited. The objective of this study was to assess NP and asthma outcomes in benralizumab-treated patients with SEA and comorbid NP in a real-world setting.

Patients And Methods: RANS was a retrospective, multi-country observational study (ClinicalTrials.

Perception of near-threshold visual stimuli is influenced by prestimulus alpha-band amplitude but not by alpha phase.

Ongoing brain activity preceding visual stimulation has been suggested to shape conscious perception. According to the pulsed inhibition framework, bouts of functional inhibition arise in each alpha cycle (every ~100 ms), allowing information to be processed in a pulsatile manner. Consequently, it has been hypothesized that perceptual outcome can be influenced by the specific phase of alpha oscillations prior to the stimulus onset, although empirical findings are controversial.

The role of brain oscillations in feature integration.

Our sensory system is able to build a unified perception of the world, which although rich, is limited and inaccurate. Sometimes, features from different objects are erroneously combined. At the neural level, the role of the parietal cortex in feature integration is well-known.
