Disordered Speech

Spectral moment analysis (SMA) is an acoustic analysis tool that shows promise for enhancing our understanding of normal and disordered speech production. It can augment auditory-perceptual analysis used to investigate differences across speakers and groups and can provide unique information regarding specific aspects of the speech signal. The purpose of this paper is to illustrate the utility of SMA as a clinical measure for both clinical speech production assessment and research applications documenting speech outcome measurements. Although acoustic analysis has become more readily available and accessible, clinicians need training with, and exposure to, acoustic analysis methods in order to integrate them into traditional methods used to assess speech production.

Markov Modulated

Let N be a stationary Markov-modulated marked point process on ℝ with intensity β ∗ and consider a real-valued functional ψ(N). In this paper we study expansions of the form Eψ(N) = a 0 + β ∗ a 1 + ·· ·+ (β∗ ) nan + o((β ∗) n ) for β ∗→ 0. Formulas for the coefficients ai are derived in terms of factorial moment measures of N. We compute a 1 and a 2 for the probability of ruin φ u with initial capital u for the risk process in the Markov-modulated environment; a 0 = 0. Moreover, we give a sufficient condition for ϕu to be an analytic function of β ∗. We allow the premium rate function p(x) to depend on the actual risk reserve.

Swallowing Evaluation

Purpose At Walter Reed National Military Medical Center, service members (SMs) with polytraumatic injuries, usually resulting from blast explosions, are routinely referred to the Speech Pathology Clinic for evaluation of swallowing function. The purpose of this clinical focus article is to advance the speech-language pathologist's (SLP) knowledge of polytrauma and to improve the care of individuals with traumatic injuries, especially related to nutrition and swallowing within a larger multidisciplinary team approach. Case Report Previous research within our center identified common demographic and injury characteristics of SMs with combat-related injuries that led to referrals for swallowing evaluation. An SM with polytraumatic injuries was selected for this case report to illustrate the relevance of the research findings and also the importance of multidisciplinary team support to appropriately manage such complex cases. Evaluations and relevant treatments are described across a 3-month acute care hospitalization, including swallowing and nutritional recommendations at the time of each swallowing evaluation. Discussion Comparisons of polytrauma cases at Walter Reed National Military Medical Center with literature from civilian trauma centers revealed somewhat longer hospitalizations and the particular influence of maxillofacial trauma on dysphagia outcomes. The complex case reported in this article illustrates the importance of multidisciplinary care and coordination, with particular emphasis on the intersecting roles of the SLP and registered dietitian. This report can serve as a guide for SLPs working in trauma settings for developing prognostic statements, treatment plans, and multidisciplinary interaction.
