Knowledge and Attitudes of Undergraduate Dental, Allied Oral Health and Nursing Students Towards Patients with Alzheimer's Disease.

Purpose Alzheimer's disease (AD) is an age-related illness that is becoming increasingly more prevalent in the United States. The purpose of this pilot study was to assess dental, allied oral health, and nursing students' perceived knowledge, comfort, and attitudes for individuals with AD.Methods A total of 851 students from a university dental and nursing school were invited to participate in this cross-sectional study. A 48-item survey comprising of demographic questions, the Alzheimer's Disease Knowledge Scale (ADKS) and the Dementia Attitudes Scale (DAS) was disseminated via an electronic survey platform. Responses were summarized as means and standard deviations or counts and rates. Comparisons of survey responses by program type and exposure to AD, age group, and prior degree were performed using the chi-square test for association and analysis of variance.Results The response rate was 33.2%. Nursing students demonstrated the highest level of knowledge on AD with mean score of 25.26 (SD 2.87), followed by dental (M=23.4, SD 3.26) and allied oral health students (M=22.10, SD 2.98). Overall, students demonstrated perceived comfort in treating patients with AD and related dementias with mean scores in the "slightly agree" range. Nursing students demonstrated the highest level of perceived comfort (M=5.61, SD 0.71).Conclusions Nursing students demonstrated higher knowledge and more positive attitudes toward AD than dental and allied oral health students. There is a need for improved educational training and an expanded didactic curriculum to enhance knowledge for dental and allied oral health students. This pilot study provides a blueprint for replication on a national level.

Students' knowledge, comfort, attitudes, and training on oral health of transgender individuals: A pilot study.

PURPOSE: The purpose of this pilot study was to evaluate students' knowledge, comfort, attitudes, and formal training on oral health of transgender individuals. METHODS: A single-site cross-sectional study of 223 students from four educational programs were invited to participate in this study. A 17-item survey was modified from two previous instruments with permission. The electronic survey was disseminated via Google Forms two times 6 weeks a part. Analyses were conducted using R version 4.1.1. Survey responses were summarized as means and standard deviations. Comparisons of survey responses by program type, age group, prior degree, and gender were performed using the chi-square test for association and analysis of variance. RESULTS: A total of118 completed the survey for a 53% response rate. Students disagreed (26.3%) they had knowledge on hormone treatments or non-hormonal treatment (40.7%) and strongly disagreed (40.7%) they had knowledge on oral manifestations of hormonal or non-hormonal therapies. Students strongly agreed they are comfortable treating transgender patients (63.6%) and believe it is the responsibility of all healthcare providers to care for transgender patients (83.1%). Students disagreed they are prepared to care for transgender patients (40.7%) or that their faculty demonstrate competency caring for transgender patients undergoing hormonal treatment (21.4%). CONCLUSION: Students are comfortable providing oral health care to transgender individuals and feel a responsibility to care for them. Formal training on hormonal and non-hormonal therapy for transgender individuals is needed in dental education programs to enhance students' knowledge and faculty competence.

Triplet and Singlet (n,π*) Excited States of 4H-Pyran-4-one Characterized by Cavity Ringdown Spectroscopy and Quantum-Chemical Calculations.

The 4H-pyran-4-one (4PN) molecule serves as a model for investigating structural changes following π* ← n electronic excitation. We have recorded the cavity ringdown (CRD) absorption spectrum of 4PN vapor at room temperature, over the wavelength region from 350 to 370 nm. This spectral region includes the T1(n,π*) ← S0 band system as well as the low-energy portion of the S1(n,π*) ← S0 system. Aided by predictions from ab initio (equation-of-motion excitation energies with dynamical correlation incorporated at the level of coupled cluster singles doubles, EOM-EE-CCSD) and density functional theory (time-dependent density functional theory with PBE0 functional, TDPBE0) calculations, we have made vibronic assignments for about 30 features in the CRD spectrum, mostly T1(n,π*) ← S0 transitions. We have used these results to correct certain vibronic assignments appearing in the previous literature for both T1(n,π*) ← S0 and S1(n,π*) ← S0 band systems. We conclude that the lowest-energy carbonyl wagging fundamentals (ν27, in-plane and ν17, out-of-plane) undergo significant frequency drops (28 and 50%, respectively) upon T1(n,π*) ← S0 excitation and similar drops (29 and 39%, respectively) for S1(n,π*) ← S0 excitation. We find that vibrational modes involving the conjugated ring atoms undergo relatively small frequency changes upon π* ← n excitation, for both T1 and S1 states. We have used the present spectroscopic results and vibronic assignments to test the accuracy of computed excited-state frequencies for 4PN. This benchmarking process shows that the economical time-dependent density functional theory method is impressively accurate for certain (but not all) vibrational modes. The highly correlated EOM-EE-CCSD ab initio method is capable of making accurate frequency predictions, but the results, unexpectedly, depend sensitively on basis set family. This anomaly is traceable to a computed conical intersection between the T1(n,π*) and T2(π,π*) surfaces near the T1(n,π*) potential minimum. Relatively small errors in the location of the conical intersection lead to enhanced mixing of the two electronic states and incorrect T1(n,π*) vibrational frequencies when certain triple-ζ quality basis sets are used.
