Comparative Study
The Stenting versus Aggressive Medical Therapy for Intracranial Arterial Stenosis Trial: Reanalysis Using the FDA "On Label" Criteria.
Due to higher rates of 1-month stroke and death with Wingspan intracranial stent placement observed in SAMMPRIS, the Food and Drug Administration (FDA) announced a more limited indication for Wingspan stent. ⋯ The new FDA "on label" criteria may identify a small group of people, who may benefit from intracranial stent placement due to higher risk of primary endpoint in those treated with best medical treatment.

Randomized Controlled Trial
Functional Near-Infrared Spectroscopy to Assess Central Pain Responses in a Nonpharmacologic Treatment Trial of Osteoarthritis.
Knee osteoarthritis (OA) is a common source of pain in older adults. Although OA-induced pain can be relieved with analgesics and anti-inflammatory drugs, the current opioid epidemic is fostering the exploration of nonpharmacologic strategies for pain mitigation. Amongs these, transcranial direct current stimulation (tDCS) and mindfulness-based meditation (MBM) hold potential for pain-relief efficacy due to their neuromodulatory effects of the central nervous system, which is known to play a fundamental role in pain perception and processing. ⋯ In conclusion, fNIRS can be effectively used to investigate neural mechanisms of pain at the cortical level in association with nonpharmacological, self-administered treatments.

Transcranial Doppler (TCD) helps identify patients with carotid dissections at risk of ischemic events (IEs). There is paucity of data identifying independent predictors of IE in vertebral arterial dissection (VAD). We sought to investigate the clinical and ultrasound predictors of IE. ⋯ TCD in VAD predicts patients at high risk of IE.

Recent studies suggest that the autoantibodies against adrenergic/muscarinic receptors might be one of the causes and potential markers of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The purpose of this study was to investigate the structural network changes related to autoantibody titers against adrenergic/muscarinic receptors in ME/CFS by performing a single-subject gray matter similarity-based structural network analysis. ⋯ Our findings suggest that β1 AdR-Ab and β2 AdR-Ab are potential markers of ME/CFS.

Virtual reality (VR) is a promising tool for distraction analgesia. This study aims to compare brain perfusion patterns while patients were undergoing burn wound care in two conditions-VR distraction and control (NoVR). ⋯ Relative decrease in cerebellar perfusion based on stringent statistical threshold in the VR environment combined with improved subjective pain experience supports the hypotheses on the role of cerebellum in perception of noxious stimuli.
