Interstitial lung abnormalities in a large clinical lung cancer screening cohort: association with mortality and ILD diagnosis.

Background: Interstitial lung abnormalities (ILA) are CT findings suggestive of interstitial lung disease in individuals without a prior diagnosis or suspicion of ILD. Previous studies have demonstrated that ILA are associated with clinically significant outcomes including mortality. The aim of this study was to determine the prevalence of ILA in a large CT lung cancer screening program and the association with clinically significant outcomes including mortality, hospitalizations, cancer and ILD diagnosis.

Quality of life predicts outcome of deep brain stimulation in early Parkinson disease.

Objective: To investigate predictors for improvement of disease-specific quality of life (QOL) after deep brain stimulation (DBS) of the subthalamic nucleus (STN) for Parkinson disease (PD) with early motor complications.

Methods: We performed a secondary analysis of data from the previously published EARLYSTIM study, a prospective randomized trial comparing STN-DBS (n = 124) to best medical treatment (n = 127) after 2 years follow-up with disease-specific QOL (39-item Parkinson's Disease Questionnaire summary index [PDQ-39-SI]) as the primary endpoint. Linear regression analyses of the baseline characteristics age, disease duration, duration of motor complications, and disease severity measured at baseline with the Unified Parkinson's Disease Rating Scale (UPDRS) (UPDRS-III "off" and "on" medications, UPDRS-IV) were conducted to determine predictors of change in PDQ-39-SI.

Long-term efficacy and tolerability of bilateral pallidal stimulation to treat tardive dyskinesia.

Objective: To confirm the efficacy and safety of deep brain stimulation (DBS) of the internal part of the globus pallidus in improving severe tardive dyskinesia (TD).

Methods: Nineteen patients with severe pharmacoresistant TD were included. All were assessed at baseline and at 3, 6 (main outcome measure), and 12 months, and in the long term (6-11 years) for 14 patients, after bilateral pallidal DBS, using motor scales (Extrapyramidal Symptoms Rating Scale [ESRS], Abnormal Involuntary Movement Scale [AIMS]), cognitive scales, and a psychiatric assessment.
