Multicenter Study Observational StudyAssociation between serum malondialdehyde levels and mortality in patients with severe brain trauma injury.
There is a hyperoxidative state in patients with trauma brain injury (TBI). Malondialdehyde (MDA) is an end-product formed during oxidative stress, concretely lipid peroxidation. In small studies (highest sample size 50 patients), higher levels of MDA have been found in nonsurviving than surviving patients with TBI. ⋯ Logistic regression analysis showed that serum MDA levels were associated with 30-day mortality (odds ratio [OR] = 4.662; 95% confidence interval [CI] = 1.466-14.824; p = 0.01), controlling for Glasgow Coma Score, age, and computed tomography findings. Survival analysis showed that patients with serum MDA levels higher than 1.96 nmol/mL presented increased 30-day mortality than patients with lower levels (hazard ratio = 3.5; 95% CI = 1.43-8.47; p < 0.001). Thus, the most relevant new finding of our study, the largest to date on serum MDA levels in patients with severe TBI, was an association between serum MDA levels and early mortality.

Multicenter Study Comparative Study Observational StudyApplication of the new GOLD COPD staging system to a US primary care cohort, with comparison to physician and patient impressions of severity.
In 2011, the traditional Global Initiative for Chronic Obstructive Lung Disease (GOLD) COPD spirometry-based severity classification system was revised to also include exacerbation history and COPD Assessment Test (CAT) and modified Medical Research Council Dyspnea Scale (mMRC) scores. This study examined how COPD patients treated in primary care are reclassified by the new GOLD system compared to the traditional system, and each system's level of agreement with patient's or physician's severity assessments. ⋯ As compared to the traditional system, the GOLD 2011 multidimensional system reclassified nearly half of patients, but how they were reclassified varied greatly by whether the mMRC or CAT questionnaire was chosen. Either way, the new system had little correlation with the PCPs or their patients' impressions about the COPD severity.

Multicenter Study Comparative StudyContinuing to confront COPD International Surveys: comparison of patient and physician perceptions about COPD risk and management.
Using data from the Continuing to Confront COPD International Physician and Patient Surveys, this paper describes physicians' attitudes and beliefs regarding chronic obstructive pulmonary disease (COPD) prognosis, and compares physician and patient perceptions with respect to COPD. ⋯ The Continuing to Confront COPD International Surveys demonstrate that while physicians and patients largely agreed about COPD management practices and the need for more effective treatments for COPD, a gap exists about the causal role of smoking in COPD.

Multicenter StudyThe risk of pediatric bicycle handlebar injury compared with non-handlebar injury: a retrospective multicenter study in Osaka, Japan.
Bicycle accidents are one of the major causes of unintentional traumatic injury in childhood. The purpose of this study was to examine characteristics and risks of handlebar injury in childhood. ⋯ Handlebar injuries in children have significant potential to cause severe damage to visceral organs, especially those in the abdomen.
