Despite considerable advances in understanding mechanisms involved in chronic pain, effective treatment remains elusive. Comorbid conditions including anxiety, depression, and cognitive impairment further impact quality of life. Chronic pain is associated with reversible changes in brain anatomy and function and with long-term changes in gene expression. ⋯ S-adenosylmethionine completely blocked nerve injury-induced cognitive impairment and attenuated SNI-induced decreases in global DNA methylation in the frontal cortex. In summary, chronic oral administration of the methyl donor, SAM, attenuated sensory and cognitive symptoms associated with nerve injury in mice. These effects may be mediated, in part, through modulation of DNA methylation in the central nervous system by systemic administration of the methyl donor SAM.

Perihematomal Edema Expansion Rates and Patient Outcomes in Deep and Lobar Intracerebral Hemorrhage.
Perihematomal edema (PHE) expansion rate may predict functional outcome following spontaneous intracerebral hemorrhage (ICH). We hypothesized that the effect of PHE expansion rate on outcome is greater for deep versus lobar ICH. ⋯ PHE72 was associated with poor functional outcomes after deep ICH, whereas PHE24 was associated with mortality for deep and lobar ICH.

Opening the Door: The Experience of Chronic Critical Illness in a Long-Term Acute Care Hospital.
Chronically critically ill patients have recurrent infections, organ dysfunction, and at least half die within 1 year. They are frequently cared for in long-term acute care hospitals, yet little is known about their experience in this setting. Our objective was to explore the understanding and expectations and goals of these patients and surrogates. ⋯ Our study describes the experience of chronically critically ill patients and surrogates in an long-term acute care hospital and the feasibility of patient-focused research in this setting. Our findings indicate overly optimistic expectations about return home and unmet palliative care needs, suggesting the need for integration of palliative care within the long-term acute care hospital. Further research is also needed to more fully understand the challenges of this growing population of ICU survivors.
