Clinician Views of Proactive Tobacco Treatment Programs: A Qualitative Evaluation.

Introduction: Proactive tobacco treatment programs are an evidence-based strategy to recruit patients who smoke to make supported quit attempts. However, such programs are rarely implemented. We performed a qualitative assessment of clinicians to inform the creation of a proactive outreach program for patients with chronic obstructive pulmonary disease (COPD) who smoke.

Functional connectivity of brain associated with passive range of motion exercise: Proprioceptive input promoting motor activation?

Soft robotics have come to the forefront of devices available for rehabilitation following stroke; however, objective evaluation of the specific brain changes following rehabilitation with these devices is lacking. In this study, we utilized functional Magnetic Resonance Imaging (fMRI) and dynamic causal modeling (DCM) to characterize the activation of brain areas with a MRI compatible glove actuator compared to the conventional manual therapy. Thirteen healthy volunteers engaged in a motor-visual fMRI task under four different conditions namely active movement, manual passive movement, passive movement using a glove actuator, and crude tactile stimulation.

More than an imitation game: Top-down modulation of the human mirror system.

All interpersonal interactions are underpinned by action: perceiving and understanding the actions of others, and responding by planning and performing self-made actions. Perception of action, both self-made and observed, informs ongoing motor responses by iterative feedback within a perception-action loop. This fundamental phenomenon occurs within single-cells of the macaque brain which demonstrate sensory and motor response properties.

Basal ganglia and cortical networks for sequential ordering and rhythm of complex movements.

Voluntary actions require the concurrent engagement and coordinated control of complex temporal (e.g., rhythm) and ordinal motor processes.

Auditory perception of a human walker.

When one hears footsteps in the hall, one is able to instantly recognise it as a person: this is an everyday example of auditory biological motion perception. Despite the familiarity of this experience, research into this phenomenon is in its infancy compared with visual biological motion perception. Here, two experiments explored sensitivity to, and recognition of, auditory stimuli of biological and nonbiological origin.

Visual spatial attention has opposite effects on bidirectional plasticity in the human motor cortex.

Long-term potentiation (LTP) and long-term depression (LTD) are key mechanisms of synaptic plasticity that are thought to act in concert to shape neural connections. Here we investigated the influence of visual spatial attention on LTP-like and LTD-like plasticity in the human motor cortex. Plasticity was induced using paired associative stimulation (PAS), which involves repeated pairing of peripheral nerve stimulation and transcranial magnetic stimulation to alter functional responses in the thumb area of the primary motor cortex.

Protocol for the Osteoporosis Choice trial. A pilot randomized trial of a decision aid in primary care practice.

Background: Bisphosphonates can reduce fracture risk in patients with osteoporosis, but many at-risk patients do not start or adhere to these medications. The aims of this study are to: (1) preliminarily evaluate the effect of an individualized 10-year osteoporotic fracture risk calculator and decision aid (OSTEOPOROSIS CHOICE) for postmenopausal women at risk for osteoporotic fractures; and (2) assess the feasibility and validity (i.e.

Induction of a chronic disease state in patients with smoldering or indolent multiple myeloma by targeting interleukin 1{beta}-induced interleukin 6 production and the myeloma proliferative component.

Objective: To conduct in vitro studies as well as a phase 2 clinical trial in patients with smoldering or indolent multiple myeloma to determine if interleukin 1 (IL-1) inhibitors can delay or prevent active myeloma.

Patients And Methods: Stromal cells were cocultured with IL-1beta-expressing myeloma cells in the presence of dexamethasone, IL-1 receptor antagonist (IL-1Ra), or both. Levels of interleukin 6 (IL-6) and of apoptosis were also quantified.

Five-year data and prognostic factor analysis of oxaliplatin and irinotecan combinations for advanced colorectal cancer: N9741.

Purpose: In this report, we update survival (OS) and time-to-progression (TTP) data for the Intergroup trial N9741 after a median 5 years of follow-up by using risk-stratified and prognostic factor analyses to determine if treatment outcomes differ in specific patient subgroups.

Patients And Methods: A total of 1,691 patients were randomly assigned to one of seven fluorouracil-, oxaliplatin-, and irinotecan-containing regimens. OS and TTP were calculated by treatment arm and baseline risk group (on the basis of WBC, performance status, number of sites of disease, and alkaline phosphatase).

Survival following recurrence in stage II and III colon cancer: findings from the ACCENT data set.

Purpose: This study was undertaken to examine five possible prognostic factors in patients with recurrent stage II and III colon cancer: time from randomization on an adjuvant therapy clinical trial to tumor recurrence (< 1 year, 1 to 2 years, 2 to 3 years, 3 to 4 years, > 4 years), initial stage (II v III), initial adjuvant treatment (fluorouracil [FU]-based v surgery alone), the era in which the patient entered an adjuvant therapy clinical trial (1978 to 1985, 1986 to 1992, 1993 to 1999), and patient age at recurrence.

Methods: The Adjuvant Colon Cancer End Points (ACCENT) data set was analyzed using univariate and multivariate Cox proportional hazards models, stratified by study.

Results: 5,722 (32.

Highly methylated genes in colorectal neoplasia: implications for screening.

Discriminant markers are required for accurate cancer screening. We evaluated genes frequently methylated in colorectal neoplasia to identify the most discriminant ones. Four genes specifically methylated in colorectal cancer [bone morphogenetic protein 3 (BMP3), EYA2, aristaless-like homeobox-4 (ALX4), and vimentin] were selected from 41 candidate genes and evaluated on 74 cancers, 62 adenomas, and 70 normal epithelia.

Immunoglobulin diversity gene usage predicts unfavorable outcome in a subset of chronic lymphocytic leukemia patients.

Survival of patients with B cell chronic lymphocytic leukemia (B-CLL) can be predicted by analysis of mutations in the immunoglobulin heavy chain variable gene (IGHV). Patients without mutations (unmutated [UM]) are at greater risk for disease progression and death than patients with mutations (M). Despite this broad prognostic difference, there remains wide intragroup variation in the clinical outcome of UM patients, especially those with low/intermediate Rai risk disease.

Updated efficacy and toxicity analysis of irinotecan and oxaliplatin (IROX) : intergroup trial N9741 in first-line treatment of metastatic colorectal cancer.

Background: Efficacy and toxicity of oxaliplatin (Eloxatin; Sanofi-Aventis, Paris, France) combined with irinotecan (IROX) were examined in 383 patients enrolled on the IROX arm of Intergroup Study N9741.

Methods: This IROX regimen was oxaliplatin 85 mg/m(2) and irinotecan 200 mg/m(2) administered every 3 weeks. The relation between adverse events on IROX to selected characteristics was analyzed.
