Radial Artery Occlusion After Cardiac Catheterization: Significance, Risk Factors, and Management.

Curr Probl Cardiol 2016 Jun 28;41(6):214-227. Epub 2016 Sep 28.

Multiple modifiable risk factors have been proposed to decrease the likelihood of developing radial artery occlusion (RAO) in patients who undergo transradial (TR) catheterization. RAO, the most significant complication for these patients, however, remains poorly identified and under diagnosed owing to its clinical quiescence and lack of clinical guidelines for systematic evaluation of radial artery patency. Currently, only best practices are available. As TR catheterization is becoming more widely adopted across the United States it has become more important to develop concrete strategies for identifying modifiable risk factors, high-risk patients, and better understanding the mechanisms to adequately approach treatment of RAO. We reviewed the contemporary literature regarding RAO and TR catheterization to provide a simplified method for discerning identifiable risk factors, high-risk groups, and management of RAO after TR catheterization.

The recovery index: A novel approach to measuring recovery and predicting remission in major depressive disorder.

J Affect Disord 2017 Jan 15;208:369-374. Epub 2016 Oct 15.

UCLA Graduate School of Education and Information Studies, United States.

Background: Clinicians view "recovery" as the reduction in severity of symptoms over time, whereas patients view it as the restoration of premorbid functioning level and quality of life (QOL). The main purpose of this study is to incorporate patient-reported measures of functioning and QOL into the assessment of patient outcomes in MDD and to use this data to define recovery.

Method: Using the STAR*D study of patients diagnosed with MDD, this present analysis grades patients' MDD severity, functioning level, and QOL at exit from each level of the study, as well as at follow-up. Using Item Response Theory, we combined patient data from functioning and QOL measures (WSAS, Q-LES-Q) in order to form a single latent dimension named the Recovery Index.

Results: Recovery Index - a latent measure assessing impact of illness on functioning and QOL - is able to predict remission of MDD in patients who participated in the STAR*D study.

Conclusions: By incorporating functioning and quality of life, the Recovery index creates a new dimension towards measuring restoration of health, in order to move beyond basic symptom measurement.

Patient-reported functioning in major depressive disorder.

Ther Adv Chronic Dis 2016 May 31;7(3):160-9. Epub 2016 Mar 31.

Department of Psychiatry, Emory University School of Medicine, Atlanta, GA, USA.

Objectives: Compared with the general population, patients with major depressive disorder (MDD) report substantial deficits in their functioning that often go beyond the clinical resolution of depressive symptoms. This study examines the impact of MDD and its treatment on functioning.

Methods: From the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial, we analyzed complete data of 2280 adult outpatients with MDD at entry and exit points of each level of antidepressant treatment and again 12 months post treatment. Functioning was measured using the Work and Social Adjustment Scale (WSAS).

Results: The results show that only 7% of patients with MDD reported within-normal functioning before treatment. The proportion of patients achieving within-normal functioning (WSAS) scores significantly increased after treatment. However, the majority of patients (>60%) were still in the abnormal range on functioning at exit. Although remitted patients had greater improvements compared with nonremitters, a moderate proportion of remitted patients continued to experience ongoing deficits in functioning after treatment (20-40%). Follow-up data show that the proportions of patients experiencing normal scores for functioning after 12 months significantly decreased from the end of treatment to the follow-up phase, from 60.1% to 49% (p < 0.0001), a finding that was particularly significant in nonremitters. Limitations of this study include the reliance on self-report of functioning and the lack of information on patients who dropped out.

Conclusion: This study points to the importance of functional outcomes of MDD treatment as well as the need to develop personalized interventions to improve functioning in MDD.
