Role of the Dental Community in HPV Vaccination Promotion

Introduction. With increasing awareness that human papillomavirus (HPV) can cause oropharyngeal cancer (OPC), dental providers may play an important role in promoting HPV vaccination and preventing cancer. Our goal was to assess knowledge and current HPV vaccine counseling practices among Vermont dentists and dental hygienists to identify potential targets for state-level interventions to increase vaccine coverage. Methods. We developed a survey to assess knowledge, beliefs, practices and barriers regarding HPV vaccination, and distributed it via email to practicing Vermont dentists and dental hygienists. Free responses were analyzed using a coding framework generated from three key informant interviews. Results. 90% of providers believe it is important for them to play an “active role” in their patients’ general medical care, yet only 50% believe it is their responsibility to recommend HPV vaccine. Only 50% feel knowledgeable enough to recommend the vaccine. 78.6% of providers rarely discuss HPV vaccination with their age-appropriate patients, and 82% rarely recommend the vaccine. When asked to name the biggest barrier against recommending vaccination, providers named the following factors most frequently: “not responsibility of dental provider” (27%); lack of confidence in knowledge (19%); time constraints (14%); and parent philosophical/religious opposition (11%). Discussion. Because dentists and dental hygienists care for a broad pediatric population across the state, dental communities may be poised to play an expanded role in Vermont’s efforts to improve its HPV vaccination coverage. Our study identifies several potential areas for provider-focused interventions, which include educating providers about the HPV vaccine and reducing significant barriers against recommending.https://scholarworks.uvm.edu/comphp_gallery/1266/thumbnail.jp

Data-Analysis System for Entry, Descent, and Landing

A report describes the Entry Descent Landing Data Analysis (EDA), which is a system of signal-processing software and computer hardware for acquiring status data conveyed by multiple-frequency-shift-keying tone signals transmitted by a spacecraft during descent to the surface of a remote planet. The design of the EDA meets the challenge of processing weak, fluctuating signals that are Doppler-shifted by amounts that are only partly predictable. The software supports both real-time and post processing. The software performs fast-Fourier-transform integration, parallel frequency tracking with prediction, and mapping of detected tones to specific events. The use of backtrack and refinement parallel-processing threads helps to minimize data gaps. The design affords flexibility to enable division of a descent track into segments, within each of which the EDA is configured optimally for processing in the face of signal conditions and uncertainties. A dynamic-lock-state feature enables the detection of signals using minimum required computing power less when signals are steadily detected, more when signals fluctuate. At present, the hardware comprises eight dual-processor personal-computer modules and a server. The hardware is modular, making it possible to increase computing power by adding computers

Barriers to Complete Adult Vaccinations in Vermont

Introduction/Background: • Child immunization is nearly universally accepted as an effective preventative measure against infectious diseases, yet adult immunization rates continue to lag behind recommended levels. • Epidemiological trends suggest a correlation between vaccine administration and decreased rates of significant morbidity and mortality, hospitalization and emergency department visits, work absenteeism, and illness associated expenses. • As of 2010, Vermont is failing to meet its adult immunization goals by 13-43%. • This study aims to understand and identify specific barriers to adult immunization in Vermont.https://scholarworks.uvm.edu/comphp_gallery/1076/thumbnail.jp

Understanding Factors Contributing to Suboptimal Rates of Childhood Vaccinations in Vermont

Introduction: Nationally, childhood immunizations have proven themselves invaluable in preventing contagious diseases and their associated morbidity and mortality. Nonetheless, vaccines have become increasingly controversial, with a growing number of parents refusing to vaccinate their children. Primary reasons given for vaccination refusal include fears of side effects and the belief that the target diseases are not harmful. Those parents who refuse to vaccinate their children generally have higher levels of education and income. An additional population of under-vaccinated children who have received limited recommended vaccinations has been identified and often comes from a lower socioeconomic level. Unimmunized children have been associated with recent disease outbreaks, placing other individuals at risk and increasing the controversy about childhood vaccinations. Nationally, Vermont has one of the highest rates of unvaccinated children with recent data showing these rates are continuing to increase.https://scholarworks.uvm.edu/comphp_gallery/1057/thumbnail.jp

Training highly qualified health research personnel: The Pain in Child Health consortium

Background and Objectives: Pain in Child Health (PICH) is a transdisciplinary, international research training consortium. PICH has been funded since 2002 as a Strategic Training Initiative in Health Research of the Canadian Institutes of Health Research, with contributions from other funding partners and the founding participation of five Canadian universities. The goal of PICH has been to create a community of scholars in pediatric pain to improve child health outcomes. Methods: Quantitative analyses enumerated PICH faculty, trainees, training activities and scientific outputs. Interviews with PICH stakeholders were analyzed using qualitative methods capturing perceptions of the program’s strengths, limitations, and opportunities for development and sustainability. Results : PICH has supported 218 trainee members from 2002 through 2013, from 14 countries and more than 16 disciplines. The faculty at the end of 2013 comprised nine co-principal investigators, 14 Canadian coinvestigators, and 28 Canadian and international collaborators. Trainee members published 697 peer-reviewed journal articles on pediatric pain through 2013, among other research dissemination activities including conference presentations and webinars. Networks have been established between new and established researchers across Canada and in 13 other countries. Perceptions from stakeholders commended PICH for its positive impact on the development of pediatric pain researchers. Stakeholders emphasized skills and abilities gained through PICH, the perceived impact of PICH training on this research field, and considerations for future training in developing researchers in pediatric pain. Conclusions: PICH has been successfully developing highly qualified health research personnel within a Canadian and international community of pediatric pain scholarship

Tunable Indistinguishable Photons From Remote Quantum Dots

Single semiconductor quantum dots have been widely studied within devices that can apply an electric field. In the most common system, the low energy offset between the InGaAs quantum dot and the surrounding GaAs material limits the magnitude of field that can be applied to tens of kVcm^-1, before carriers tunnel out of the dot. The Stark shift experienced by the emission line is typically 1 meV. We report that by embedding the quantum dots in a quantum well heterostructure the vertical field that can be applied is increased by over an order of magnitude whilst preserving the narrow linewidths, high internal quantum efficiencies and familiar emission spectra. Individual dots can then be continuously tuned to the same energy allowing for two-photon interference between remote, independent, quantum dots

Lis1 and doublecortin function with dynein to mediate coupling of the nucleus to the centrosome in neuronal migration

Humans with mutations in either DCX or LIS1 display nearly identical neuronal migration defects, known as lissencephaly. To define subcellular mechanisms, we have combined in vitro neuronal migration assays with retroviral transduction. Overexpression of wild-type Dcx or Lis1, but not patient-related mutant versions, increased migration rates. Dcx overexpression rescued the migration defect in Lis1 (+/−) neurons. Lis1 localized predominantly to the centrosome, and after disruption of microtubules, redistributed to the perinuclear region. Dcx outlined microtubules extending from the perinuclear “cage” to the centrosome. Lis1 (+/−) neurons displayed increased and more variable separation between the nucleus and the preceding centrosome during migration. Dynein inhibition resulted in similar defects in both nucleus–centrosome (N-C) coupling and neuronal migration. These N-C coupling defects were rescued by Dcx overexpression, and Dcx was found to complex with dynein. These data indicate Lis1 and Dcx function with dynein to mediate N-C coupling during migration, and suggest defects in this coupling may contribute to migration defects in lissencephaly

Detection of intracochlear damage during cochlear implant electrode insertion using extracochlear measurements in the gerbil

An intraoperative monitoring algorithm during cochlear implant electrode insertion could be used to detect trauma and guide electrode placement relative to surviving hair cells. The aim of this report was to assess the feasibility of using extracochlear recording sites to monitor acoustically evoked responses from surviving hair cells and neural elements during implantation in an animal model
