Effect of the COVID-19 pandemic on unmet healthcare needs after hospital discharge in acute respiratory failure survivors: A multicenter prospective cohort study.

Survivors of acute respiratory failure (ARF) have complex healthcare needs postdischarge, frequently resulting in unmet needs. This prospective multicenter study explores the association between COVID-19 status and unmet healthcare needs in survivors of ARF following hospital discharge. We analyzed patient characteristics and unmet healthcare needs by COVID-19 status using a multivariable regression model with propensity weights.

Cilioretinal Sparing Central Retinal Artery Occlusion from Giant Cell Arteritis.

A 93-year-old woman presented with a 1-day history of sudden painless vision loss in her right eye with a background of new temporal headaches and jaw claudication. Dilated fundus examination of the right eye showed mild retinal whitening and edema throughout the right fundus with selective sparing in the distribution of the cilioretinal artery. A diagnosis of giant-cell arteritis (GCA) was made and confirmed with temporal artery biopsy.

Paracentral Acute Middle Maculopathy Associated With Anterior Ischemic Optic Neuropathy and Cilioretinal Artery Occlusion in Giant Cell Arteritis.

Paracentral acute middle maculopathy (PAMM) is a relatively new optical coherence tomography finding, defined by hyperreflectivity in the inner nuclear layer. In this article, we present a case of a 73-year-old woman who presented with transient vision loss followed by the sudden onset of complete vision loss to counting fingers at 1 foot for one day in the left eye. Dilated examination showed a right cotton wool spot, left pallid optic disc edema, and retinal edema in the distribution of the cilioretinal artery.

Oxysterol modulates neurotransmission via liver-X receptor/NO synthase-dependent pathway at the mouse neuromuscular junctions.

Elimination of brain cholesterol occurs in the form of 24S-hydroxycholesterol (24S-HCh) that may modulate physiological processes outside the brain. Here, using microelectrode recording of postsynaptic responses (end-plate potentials, EPPs) and fluorescent marker (FM1-43) for endo-exocytosis we studied the effects of prolonged application of 24S-HCh (2.5 h, 0.

24S-hydroxycholesterol suppresses neuromuscular transmission in SOD1(G93A) mice: A possible role of NO and lipid rafts.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by the initial denervation of skeletal muscle and subsequent death of motor neurons. A dying-back pattern of ALS suggests a crucial role for neuromuscular junction dysfunction. In the present study, microelectrode recording of postsynaptic currents and optical detection of synaptic vesicle traffic (FM1-43 dye) and intracellular NO levels (DAF-FM DA) were used to examine the effect of the major brain-derived cholesterol metabolite 24S-hydroxycholesterol (24S-HC, 0.
