ABSTRACT
The aim of the study is to determine the utility of echocardiography in the assessment of diastolic function in children and young adults with restrictive cardiomyopathy (RCM). RCM is a rare disease with high mortality requiring frequent surveillance. Accurate, noninvasive echocardiographic measures of diastolic function may reduce the need for invasive catheterization. Single-center, prospective, observational study of pediatric and young adult RCM patients undergoing assessment of diastolic parameters by simultaneous transthoracic echocardiogram (TTE) and invasive catheterization. Twenty-one studies in 15 subjects [median (IQR) = 13.8 years (7.0-19.2), 60% female] were acquired with median left ventricular end-diastolic pressure (LVEDP) 21 (IQR 18-25) mmHg. TTE parameters of diastolic function, including pulmonary vein A wave duration (r s = 0.79) and indexed left atrial volume (r s = 0.49), demonstrated significant positive correlation, while mitral valve A (r s = -0.44), lateral e' (r s = -0.61) and lateral a' (r s = -0.61) velocities showed significant negative correlation with LVEDP. Lateral a' velocity (≤0.042 m/s) and pulmonary vein A wave duration (≥156 m/s) both had sensitivity and specificity ≥80% for LVEDP ≥ 20 mmHg. In pediatric and young adult patients with RCM, lateral a' velocity and pulmonary vein A wave duration predicted elevated LVEDP with high sensitivity and specificity; however, due to technical limitations the latter was reliably measured in 12/21 patients. These noninvasive parameters may have utility in identifying patients that require further assessment with invasive testing. These findings require validation in a multicenter prospective cohort prior to widespread clinical implementation.

Our single center experience with pancreas transplantation (PTx) over an 11+ year period is reviewed. METHODS: We retrospectively studied outcomes in 202 consecutive PTxs in 192 patients at our center. All patients received either rabbit anti-thymocyte globulin (rATG) or alemtuzumab (Alem) induction with tacrolimus/mycophenolate mofetil and tapered steroids or early withdrawal. 179 PTxs (89%) were performed with portal-enteric and 23 with systemic-enteric drainage. RESULTS: From 11/01 to 3/13, we performed 162 simultaneous kidney-PTxs (SKPT), 35 sequential PTxs after kidney, and 5 PTx alone (40 solitary PTxs, SPT). 186 PTxs (92%) were primary and 16 were pancreas retransplants. With a mean follow-up of 5.5 years, overall patient (86% SKPT versus 87% SPT), kidney (74% SKPT versus 80% SPT), and pancreas graft survival (both 65%) rates were comparable. Causes of PTx loss were also similar between SKPT and SPT; the rates of early thrombosis were 8.6% and 5%, respectively. Acute rejection rates were similar between groups (SKPT 29% versus SPT 28%, p= not significant). A randomized trial of Alem versus rATG induction in SKPT demonstrated lower rates of acute rejection and infection in the Alem group. Consequently, Alem induction has been used exclusively in all PTxs since 2009. Early steroid elimination has been feasible in most patients. Surveillance PTx biopsy-directed immunosuppression has contributed to equivalent long-term outcomes in SKPT and SPT. Good results have been achieved in African-American patients and in patients with a type 2 diabetes phenotype. CONCLUSIONS: Excellent 5-year outcomes following PTx can be achieved as >86% of patients are alive, >87% of surviving patients are dialysis-free, 80% of surviving patients remain insulin-free, and 88% of surviving patients have detectable C-peptide levels.
ABSTRACT
National reports outlining disparities in oral health care in the United States have focused attention on ways to encourage health care providers to become more involved in the public health arena. Utilization of service-learning in professional health education programs is one method being explored. The purpose of this study was to conduct a retrospective review of a service-learning rotation within a dental hygiene public health course. The study utilized data sources generated by students as part of a course evaluation. These sources included student journals (qualitative/quantitative) and Likert-scaled (quantitative) and open-ended (qualitative) student satisfaction survey items. Mixed methodology data analysis techniques were used to analyze and triangulate data in order to form conclusions related to the effectiveness of service-learning as a teaching strategy in dental hygiene. This investigation suggests that service-learning is an effective learning strategy for increasing student awareness of underserved populations, cultural diversity, and ethical patient care. The study also suggests that service-learning helped students to determine their level of interest in public health as a career choice by giving them a real-world experience in public health patient care.

In 2004 personnel from the Missouri Area Health Education Centers and faculty from the University of Missouri-Kansas City, School of Dentistry, Division of Dental Hygiene, joined forces to develop dental hygiene student rotations to rural and underserved areas. Twenty-six students participated in a two week rotation to Federally Qualifed Health Centers throughout Missouri. The rotations included objectives which focused on student familiarity with 1) the similarities and differences between private practice and public health clinics, 2) assessing, planning, implementing and evaluating an oral health education program, 3) working with a diverse population; and 4) an understanding of the ethics of delivering healthcare to a whole community versus individual patients. Additionally, the rotation sought to continue to develop the students' clinical skills under supervised instruction. The rotation was evaluated using various qualitative and quantitative measurements, including journals, task records and post-program surveys. This article reports on the results of the qualitative and quantitative measures used for evaluating the objectives of the project.
