Comparative Study
Differences in pain-related fear acquisition and generalization: an experimental study comparing patients with fibromyalgia and healthy controls.
Anomalies in fear learning, such as failure to inhibit fear to safe stimuli, lead to sustained anxiety, which in turn may augment pain. In the same vein, stimulus generalization is adaptive as it enables individuals to extrapolate the predictive value of 1 stimulus to similar stimuli. However, when fear spreads in an unbridled way to novel technically safe stimuli, stimulus generalization becomes maladaptive and may lead to dysfunctional avoidance behaviors and culminate in severe pain disability. ⋯ Fear of movement-related pain spreads selectively to novel movements similar to the original painful movement, and not to those resembling the nonpainful movement in the healthy controls, but nondifferential fear generalization was observed in FM. As expected, in the unpredictable context, we also observed nondifferential fear generalization; this effect was more pronounced in FM. Given the status of overgeneralization as a plausible transdiagnostic pathogenic marker, we believe that this research might increase our knowledge about pathogenesis of musculoskeletal widespread pain.

The prognostic value of the fracture level in the treatment of Gartland type III supracondylar humeral fracture in children.
A small proportion of children with Gartland type III supracondylar humeral fracture (SCHF) experience troubling limited or delayed recovery after operative treatment. We hypothesised that the fracture level relative to the isthmus of the humerus would affect the outcome. We retrospectively reviewed 230 children who underwent closed reduction and percutaneous pinning (CRPP) for their Gartland type III SCHFs between March 2003 and December 2012. ⋯ Age over ten years was also a poor prognostic factor for recovery of the range of elbow movement (p = 0.027). This is the first study demonstrating a subclassification system of Gartland III fractures with prognostic significance. This will guide surgeons in peri-operative planning and counselling as well as directing future research aimed at improving outcomes.

Randomized Controlled Trial Multicenter Study Observational Study
Association between biomarkers of endothelial injury and hypocoagulability in patients with severe sepsis: a prospective study.
Patients with severe sepsis often present with concurrent coagulopathy, microcirculatory failure and evidence of vascular endothelial activation and damage. Given the critical role of the endothelium in balancing hemostasis, we investigated single-point associations between whole blood coagulopathy by thrombelastography (TEG) and plasma/serum markers of endothelial activation and damage in patients with severe sepsis. ⋯ In our cohort of patients with severe sepsis, higher circulating levels of biomarkers of mainly endothelial damage were independently associated with hypocoagulability assessed by TEG and FF. Endothelial damage is intimately linked to coagulopathy in severe sepsis.

ReviewComprehensive rehabilitative care across the spectrum of amyotrophic lateral sclerosis.
Amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease) is a neurodegenerative disease that results in progressive muscle weakness and wasting. There is no known cure and the disease is uniformly fatal. ⋯ Patient-centered, multidisciplinary care has a significant impact on the life of people with ALS and is the current standard of care for this patient population.

The long-term attributable burden related to acute respiratory distress syndrome (ARDS) is not fully investigated. The aim of this study is to evaluate the quality of life (QOL) and functional status at 6 months after hospitalization in patients at risk for ARDS who did and did not develop the syndrome. ⋯ In this population-based study, decreased QOL and functional status 6 months after hospitalization were largely explained by baseline condition, with similar recovery in survivors who did and did not develop ARDS.
