Different Factors Influencing Postural Stability during Transcutaneous Electrical Stimulation of the Cervical Spinal Cord.

Transcutaneous spinal cord stimulation (tSCS) is a promising noninvasive alternative to epidural stimulation. However, further studies are needed to clarify how tSCS affects postural control. The aim of this study was to investigate the effect of transcutaneous cervical spinal cord stimulation on postural stability in healthy participants via computerized stabilization.

A novel extracellular vesicle paradigm for the treatment of COVID-19 induced acute respiratory distress syndrome (ARDS).

Efficacy of mesenchymal stem cells (MSCs) for treatment of acute respiratory distress syndrome (ARDS) suggests bioactive bone marrow MSC extracellular vesicles (BM-MSC EVs) may be effective. A patient with severe COVID-19 associated ARDS who was presumed to expire was treated with a BM-MSC EV preparation (14 doses over two months) as a rescue treatment for refractory COVID ARDS. Near complete reversal of lung inflammation and fibrosis (per computed tomography), near complete restoration of mobility, hospital discharge (3 months) with resumption of normal activities of daily living (one year) and return to work occurred.

Developing an educational "hub": impact of a distance-learning curriculum in a multinational cohort.

Purpose: To address a gap in radiation oncology education in low- and middle-income countries (LMICs), we sought to evaluate the effectiveness and generalizability of a refined curriculum on intensity modulated radiotherapy (IMRT) offered to existing radiation therapy (RT) clinics across Africa and Latin America (LATAM) at no cost.

Methods: A curriculum was created based on prior needs assessments and adapted for participating medical physicists, radiation oncologists, radiation therapists, and trainees in LMICs. English-speaking and Spanish-speaking teams of volunteer educators delivered 27 hour-long sessions 1-2 times weekly for 4 months using video conferencing to African and LATAM cohorts, respectively.

[Monomelic amyotrophy].

Monomelic amyotrophy, also known as Hirayama disease, is a rare neurological disorder characterized by focal and latent onset of upper limb weakness and atrophy in the absence of sensory deficits, bulbar or pyramidal signs. It usually occurs in young patients. The disease usually begins unnoticeably and progresses slowly, and can manifest itself as unilateral or asymmetrical weakness, as well as atrophy of the distal upper limb.

Chlamydia pneumoniae-immunoglobulin E antibody responses in serum from children with asthma.

Chlamydia pneumoniae is an obligate intracellular bacterium that causes respiratory infections in humans. An association between persistent C. pneumoniae infection and asthma pathogenesis has been described.
