To establish the scope of the problem of chronic pain in the population, we need to extend the focus on prevalence, the most frequently studied factor. Among other important factors is the complex relationship between the temporal characteristics of pain and their impact on peoples' lives. The purpose of the present study was to describe the characteristics of chronic pain, including pattern, severity, location, spread, and duration, in a population-based sample and to investigate the relationships between pain pattern and impact on the individual's life measured by interference with life and health-related quality of life (HRQoL). ⋯ Hierarchical stepwise regression analyses showed that pain pattern and severity accounted for 44.4% variance for life interference. The range of the variances for these variables for the five domains of HRQoL was from 7.3% (mental health) to 53.3% (bodily pain). Pain pattern and severity are the most significant predictors of the impact of chronic pain on individual's daily life.

Eotaxin-3 activates Smad through the TGF-β1 pathway in chronic subdural hematoma outer membranes.
Chronic subdural hematoma (CSDH) is considered to be an inflammatory disease. Eosinophils are frequently expressed in the outer membrane of CSDH and are major sources of transforming growth factor beta (TGF-β). The mothers against decapentaplegic (Smad)-signaling pathway, which is activated by TGF-β, has been shown to be involved with fibrosis. ⋯ Smad3 was shown to be present in fibroblasts. These findings indicate that eotaxin-3 is expressed in CSDH fluid, inducing eosinophils into the outer membrane and resulting in elevation of TGF-β with the Smad pathway activated by TGF-β. These data suggest a potential mechanism for CSDH formation and growth.

Chronic obstructive pulmonary disease (COPD) is characterized by expiratory flow limitation (EFL) due to progressive airflow obstruction. The various mechanisms that cause EFL are central to understanding the physiopathology of COPD. At the end of expiration, dynamic inflation may occur due to incomplete emptying the lungs. ⋯ When invasive MV is used, settings should be adjusted in a way that minimizes hyperinflation, while providing reasonable gas exchange, respiratory muscle rest, and proper patient-ventilator interaction. Further, weaning from MV may be difficult in these patients, and factors amenable to pharmacological correction (such as increased bronchial resistance, tracheobronchial infections, and heart failure) are to be systematically searched and treated. In selected patients, early use of NIV may hasten the process of weaning from MV and improve outcomes.

Comparative StudyFeasibility of a Multiple-Choice Mini Mental State Examination for Chronically Critically Ill Patients.
Following treatment in an ICU, up to 70% of chronically critically ill patients present neurocognitive impairment that can have negative effects on their quality of life, daily activities, and return to work. The Mini Mental State Examination is a simple, widely used tool for neurocognitive assessment. Although of interest when evaluating ICU patients, the current version is restricted to patients who are able to speak. This study aimed to evaluate the feasibility of a visual, multiple-choice Mini Mental State Examination for ICU patients who are unable to speak. ⋯ Administration of the multiple-choice Mini Mental State Examination to ICU patients was straightforward and produced exploitable results comparable to those of the standard Mini Mental State Examination. It should be of interest for the assessment and monitoring of the neurocognitive performance of chronically critically ill patients during and after their ICU stay. The multiple-choice Mini Mental State Examination tool's role in neurorehabilitation and its utility in monitoring neurocognitive functions in ICU should be assessed in future studies.

Prolonged Opioid Use After Knee Arthroscopy in Military Veterans.
Chronic postoperative pain occurs with an appreciable incidence after elective surgery. Known risk factors include perioperative pain and posttraumatic stress disorder (PTSD). Military veterans are a population at particular risk for PTSD and hence may be at increased risk for chronic pain after surgery. Our goal was to identify risk factors for chronic postoperative pain in young veterans after minor elective surgery, including the contribution of PTSD. ⋯ This single-center retrospective study suggests that the most important predictor of chronic postoperative pain is preoperative opioid use. For patients not taking opioids preoperatively, PTSD may increase the risk of prolonged postoperative opioid prescriptions and chronic postoperative pain, potentially related to patient age.
