Introduction/aims: Claims-based analyses have demonstrated high medical costs associated with myasthenia gravis (MG). We examined the economic burden of MG from the perspective of affected people and their families.

Methods: The Muscular Dystrophy Association developed and conducted an online survey of people with MG and their caregivers between October 26 and December 6, 2021.

Fall risk assessment is a complex phenomenon involving several risk factors, including an individual's balance and mobility status, chronic health conditions, visual impairment, hearing deficits, environmental hazards (e.g., loose rugs, clutter), and being homebound or semi-homebound.

Objectives: External laryngeal manipulation is a commonly used maneuver to improve visualization of the glottis during tracheal intubation in children. However, the effectiveness to improve tracheal intubation attempt success rate in the nonanesthesia setting is not clear. The study objective was to evaluate the association between external laryngeal manipulation use and initial tracheal intubation attempt success in PICUs.

Perineuronal nets (PNN) are aggregations of chondroitin sulfate proteoglycans surrounding the soma and proximal processes of neurons, mostly GABAergic interneurons expressing parvalbumin. They limit the plasticity of their afferent synaptic connections. In zebra finches PNN develop in an experience-dependent manner in the song control nuclei HVC and RA (nucleus robustus arcopallialis) when young birds crystallize their song.

Songbirds learn individually unique songs through vocal imitation and use them in courtship and territorial displays. Previous work has identified a forebrain auditory area, the caudomedial nidopallium (NCM), that appears specialized for discriminating and remembering conspecific vocalizations. In zebra finches (ZFs), only males produce learned vocalizations, but both sexes process these and other signals.

Estradiol (E2) has recently been shown to modulate sensory processing in an auditory area of the songbird forebrain, the caudomedial nidopallium (NCM). When a bird hears conspecific song, E2 increases locally in NCM, where neurons express both the aromatase enzyme that synthesizes E2 from precursors and estrogen receptors. Auditory responses in NCM show a form of neuronal memory: repeated playback of the unique learned vocalizations of conspecific individuals induces long-lasting stimulus-specific adaptation of neural responses to each vocalization.

Gonadal hormones modulate behavioral responses to sexual stimuli, and communication signals can also modulate circulating hormone levels. In several species, these combined effects appear to underlie a two-way interaction between circulating gonadal hormones and behavioral responses to socially salient stimuli. Recent work in songbirds has shown that manipulating local estradiol levels in the auditory forebrain produces physiological changes that affect discrimination of conspecific vocalizations and can affect behavior.
