Mean Streets and Mental Health: Depression and Post-Traumatic Stress Disorder at Crime Hot Spots.

This study explores the relationship between mental health and place at microgeographic units of analysis. We examine self-reported symptomology for depression and PTSD for 2,724 survey respondents interviewed in three types of randomly selected street segments: violent crime hot spots, cool spots, and cold spots. We find that the mean symptomology score is 61% higher for depression in violent crime hot spots than cold spots, and 85% higher for PTSD.

Issues of rigor and feasibility when observing the quality of program implementation: a case study.

Program evaluators have paid little attention in the literature to the manner in which measuring the quality of implementation with observations requires tradeoffs between rigor (reliability and validity) and program evaluation feasibility. We present a case example of how we addressed rigor in light of feasibility concerns when developing and conducting observations for measuring the quality of implementation of a small education professional development program. We discuss the results of meta-evaluative analyses of the reliability of the quality observations, and we present conclusions about conducting observations in a rigorous and feasible manner.

Objectives/hypothesis: Investigate the localization mechanisms of bone marrow stromal cells following transient ischemia-reperfusion injury in a murine flap model.

Study Design: Controlled laboratory study.

Methods: A cutaneous flap based on the inferior epigastric artery was elevated, and transient ischemia of 3.

Airway salvation after failed anterior graft in a child with long segment stenosis.

Objectives: 1-Recognize difficulties and review techniques in long-segment laryngotracheal stenosis repair. 2-Contribute to increasing clinical and surgical skills in pediatric airway reconstruction through reporting our experience with a novel reconstruction technique involving use of a failed anterior graft and prolonged postoperative stenting.

Case Report: 10 year old male with history of burn injury who required a tracheostomy due to prolonged intubation/inhalational injury in 2005.
