Noninvasive and minimally invasive extracranial stimulation has now been widely investigated for the treatment of primary headache disorders, particularly migraine. In this review, we describe methodological challenges in studying occipital and supraorbital stimulation devices. We explore the efficacy and safety of implantable occipital nerve stimulation for primary headache disorders, including the 3 randomized, sham-controlled clinical trials for chronic migraine treatment. We also review noninvasive supraorbital transcutaneous stimulation as a preventive therapy for episodic migraine.

To investigate self-reported pain in young adults with a low birth weight. ⋯ Results of our study imply that pain should be in focus when conducting long-term follow-up programs of individuals with a low birth weight.

A population-based study on epidemiology of intensive care unit treated traumatic brain injury in Iceland.
Traumatic brain injury is a worldwide health issue and a significant cause of preventable deaths and disabilities. We aimed to describe population-based data on intensive care treated traumatic brain injury in Iceland over 15 years period. ⋯ Incidence decreased with a shift in injury mechanism from road traffic accidents to falls and an increased rate of traumatic brain injury in older patients following a fall from standing or low heights. Mortality was higher in older patients falling from low heights than in younger patients suffering multiple injuries in road traffic accidents. Age, injury severity score, acute physiology and chronic health evaluation II score and Marshall score are good prognostic factors for outcome. Traumatic brain injury continues to be a considerable problem and the increase in severe traumatic brain injury in the middle age and older age groups after a seemingly innocent accident needs a special attention.

Exacerbation of pain by chronic stress and comorbidity of pain with stress-related psychiatric disorders, including anxiety and depression, represent significant clinical challenges. However, the underlying mechanisms still remain unclear. Here, we investigated whether chronic forced swim stress (CFSS)-induced exacerbation of neuropathic pain is mediated by the integration of stress-affect-related information with nociceptive information in the central nucleus of the amygdala (CeA). ⋯ Suppression of CFSS-elicited depressive-like behaviors by antidepressants imipramine or ifenprodil inhibits the CFSS-induced exacerbation of neuropathic pain. Collectively, our findings suggest that CFSS potentiates synaptic efficiency of the BLA-CeA pathway, leading to the activation of GluN2B-NMDA receptors and sensitization of CeA neurons, which subsequently facilitate pain-related synaptic plasticity of the PB-CeA pathway, thereby exacerbating SNI-induced neuropathic pain. We conclude that chronic stress exacerbates neuropathic pain via the integration of stress-affect-related information with nociceptive information in the CeA.

Impact of Acute Kidney Injury in Patients Hospitalized With Pneumonia.
Pneumonia is a common cause of hospitalization and can be complicated by the development of acute kidney injury. Acute kidney injury is associated with major adverse kidney events (death, dialysis, and durable loss of renal function [chronic kidney disease]). Because pneumonia and acute kidney injury are in part mediated by inflammation, we hypothesized that when acute kidney injury complicates pneumonia, major adverse kidney events outcomes would be exacerbated. We sought to assess the frequency of major adverse kidney events after a hospitalization for either pneumonia, acute kidney injury, or the combination of both. ⋯ When acute kidney injury accompanies pneumonia, postdischarge outcomes are worse than either diagnosis alone. Patients who survive a pneumonia hospitalization and develop acute kidney injury are at high risk for major adverse kidney events including death and should receive careful follow-up.
