Abstract
BACKGROUND Analogous to the situation in other disciplines, digital ENT teaching made significant progress during the pandemic. Most ENT clinics nationwide were able to offer a complete virtual teaching program in time. Innovative teaching methods were also used early on. This was recognized in student teaching evaluations. Due to the expansion of virtual reality (VR) in medical teaching, even greater satisfaction should be expected through improved teaching quality. MATERIALS AND METHODS Surveys were performed with students (n = 180) of the ENT block internship in the summer semester of 2023. The aim of the evaluation was to determine the students' satisfaction with and subjective effectiveness of the newly implemented VR digital teaching method for teaching ear anatomy and coniotomy. A survey was also carried out among resident physicians. RESULTS The ENT teaching was perceived favorably by the students, with an average rating of 11.7 out of 15. The learning effectiveness and the value of VR in the ENT learning portfolio was evaluated varyingly by the students. The physicians' assessment was different, with a more positive perception. CONCLUSION Virtual reality represents an innovative component in the teaching portfolio of otolaryngology. This new teaching method is viewed and accepted as a future-oriented tool. Remarkably, the physicians involved voted consistently positively, while the students gave more critical assessments and pointed out limitations in the individual and subjective areas. These findings are in contrast to the further development of innovative teaching methods demanded by student interest groups.

Abstract
Behavioral and psychological symptoms of dementia (BPSD) are highly prevalent in long-term care settings. We sought to enhance the knowledge, skills, and attitudes of primary care clinicians caring for patients with BPSD through academic detailing, an evidence-based approach for persuading health care professionals to make changes in their practice. We implemented academic detailing among physicians and nurse practitioners in 2 primary care settings, one an urban center serving a largely Black community and another a rural center serving a largely white community, within primary care-integrated dementia diagnostic clinics. Each of the 11 academic detailing visits included didactic content, case discussion, and patient consultation. Outcome measures included assessments of clinicians' knowledge, confidence, and acceptability of the intervention. Of 15 providers who participated at baseline, 13 participated in 1 or more academic detailing visits in the next 18 months, 12 completed a 6-month assessment, and 7 completed an 18-month assessment. Knowledge and attitudes about BPSD increased during the program, and there was high satisfaction with the program. Academic detailing thus is a feasible way of improving self-reported knowledge, skills, and attitudes of primary care clinicians caring for patients with BPSD. We plan to scale up the intervention to assess the impact on patient and caregiver outcomes.

Abstract
INTRODUCTION Approximately 5%-12% of the population worldwide suffer from chronic rhinosinusitis (CRS). CRS is defined as a chronic respiratory disease and is considered to be a risk factor for COVID-19 patients. AREAS COVERED A non-systematic literature research was conducted on COVID-19 and treatment options for CRSwNP. The latest international publications in medical databases, international guidelines, and the internet were reviewed. Since there were no publications on all aspects of this topic during the pandemic, we included our own experience in this report. Based on the conducted literature research in addition to our previously reported experience, we discuss the treatment of CRSwNP during the COVID-19 pandemic and what can be taken for future pandemics. EXPERT OPINION Intranasal corticosteroids remain the standard treatment for CRS in patients with SARS-CoV-2 infection. Indications for surgical treatment of CRS should be critically evaluated and reserved for patients with complications and those with no other treatment options. For this purpose, COVID-19 status should be known if possible and, in case of unclear status (emergency), using appropriate personal protective equipment. Systemic corticosteroids should be avoided were possible. Biological treatment should be continued under careful monitoring in uninfected patients and should be temporarily interrupted during COVID-19 infection.

Abstract
BACKGROUND Traumatology of the head and neck region is not only a part of otorhinolaryngology, but also has a large overlap with neighboring disciplines of the head and neck region. In Freiburg, an interdisciplinary lecture on "ENT emergencies" was implemented in the 21/22 winter semester. The aim was to provide an even more realistic view on interdisciplinary patient care and to make evident the areas of intersection of four of the major head disciplines (otorhinolaryngology, neurosurgery, ophthalmology, and maxillofacial surgery). MATERIALS AND METHODS A new, special lecture in otorhinolaryngology was implemented as part of the regular online lecture series accompanying the semester. With reference to the clinical care of ENT emergencies, possible overlaps with neighboring disciplines were identified and explained by the discipline representatives or discussed in front of and with the auditorium. At the end of the semester, all participating students (n = 173) were invited to evaluate the seminar using the survey tool "EvaSys" (EvaSys GmbH, Lüneburg, Germany). In total, 78 students participated in the evaluation process. RESULTS The new lecture concept was very well accepted and immediately ranked top among the interdisciplinary lecture titles within the ENT lecture series. The clear communication of the term "interdisciplinarity" in the sense of a complementary clinical cooperation was also very successful and was appreciated accordingly by students during the evaluation process. CONCLUSION Pragmatic presentation of ideal clinical patient care using an interdisciplinary approach is possible within the regular ENT lecture series. This realistic portrayal, beyond any technical and/or professional differences, is of great interest to students and is considered clinically relevant. Thus, interdisciplinary lectures provide a valuable tool to teach the fundamental values of clinical interdisciplinary management for the best possible patient care.

Abstract
Most persons living with dementia (PLWD) exhibit behavioral or psychological symptoms of dementia (BPSD) over the course of the illness. The DICE Approach (DICE) is a framework that enables caregivers to identify, evaluate, and manage BPSD. This pilot pre-post test study examined the effects of DICE training on dementia care professionals' self-efficacy, knowledge, and attitudes regarding care of patients with BPSD. Participants underwent either in-person DICE training or, during the pandemic, online training. Case consultations were offered as additional learning opportunities in challenging situations. Of 134 participants in the trainings, 122 (91.0%) provided survey data for one or more instruments before and after training. Participants experienced significant improvement in knowledge and attitudes with respect to BPSD and improvement in self-efficacy with respect to helping caregivers respond to BPSD. Training dementia care professionals in DICE can improve their capacity to support caregivers in the management of BPSD.

Abstract
INTRODUCTION Approximately 90% of persons with dementia experience behavioral and psychological symptoms of dementia (BPSD) over the course of their illness. Primary care clinicians often provide care as specialty geriatric-medicine or -psychiatry consultation may be difficult to obtain. Academic detailing (AD) is an evidence-based educational approach for engaging and persuading healthcare professionals to make changes in their practice (Avorn 2017). We sought to enhance the knowledge, skills and attitudes of providers' care of patients with BPSD using the AD model in primary care. METHODS We implemented AD in an urban clinic serving a largely Black community and a rural clinic serving a large, White community. Each AD visit included didactic content, case discussion, and consultation regarding patients with BPSD. Eleven visits over 18 months are planned for each site. Outcome measures include a 10-item multiple-choice assessment of knowledge and an adaptation of the General Practitioners Attitude and Confidence Scale for Dementia (GPACS-D) (Mason et al. 2019) at baseline before training, and 6 and 18 months, and Likert-scale measurement of acceptability at 6 and 18 months, all self-report. RESULTS We present interim data. Five urban and 14 rural providers completed baseline assessments. Providers were mostly White (95%) and Non-Hispanic (100%); 47% were female. Urban and rural providers had similar baseline BPSD knowledge (mean (SD) of correct answers, 5.4 (1.7) for rural, and 5.0 (2.6) for urban). The adapted GPACS-D, where higher score indicates more confidence, showed less confidence (mean score 11.4 versus 16.6, p=0.01) in urban versus rural providers. The overall attitudes score indicate there may be more confidence in treating BPSD at baseline among the slightly older rural providers as compared to their urban colleagues. Thus far, eight of 22 planned AD visits have been completed; 6-month assessments are forthcoming and will be presented. DISCUSSION Academic detailing may be a feasible and effective way of increasing self-reported knowledge and skills and improving self-reported attitude of primary care providers responsible for the care of patients with BPSD. The pilot data collected in this study will inform the design of a larger study to measure the impact of AD on patient outcomes.

Abstract
INTRODUCTION Most persons living with dementia will exhibit at least one behavioral or psychological symptom of dementia (BPSD) (Kales, et al., 2015). As brain pathology progresses, challenging behaviors can increase in frequency and severity, causing an increase in caregiver stress and burden. Furthermore, BPSD can result in unplanned hospitalizations and unnecessary use of psychotropic medications. Non-pharmacological management of BPSD should be the first line of treatment. The DICE (Describe, Investigate, Create, Evaluate) ApproachTM was developed by experts from the University of Michigan and John Hopkins University, to help caregivers learn how to identify and manage BPSD. This project describes a statewide implementation of the DICE approach with community-based dementia care providers. METHODS From September 2017 to April 2020, we held four DICE trainings (three in-person trainings, one web-based training) for Dementia Care Specialists (DCSs) and other dementia care professionals who work directly with family caregivers of people with dementia in Wisconsin. We assessed trainees' knowledge and attitudes from the Dementia Attitudes Scale (DAS) and the Knowledge about Memory Loss and Care test (KAML-C) at baseline of training, immediately after training, and six months after training. Consultations were provided to address challenging cases. RESULTS Participants (N=136) in both in-person and online DICE trainings experienced significant changes in knowledge, self-efficacy and attitudes from baseline to post-training (immediately after training) assessments (p<.01) (see Table 2 for details). Narrative feedback from trainees was generally very positive. Trainees used DICE with 165 caregivers who were primarily non-Hispanic white (92%) females (74.4%) from an urban location (68.1%), caring for their spouse (52.7%) (Table 1). DISCUSSION By using the DICE approach with caregivers of persons with dementia, Wisconsin's DCSs and other dementia professionals are uniquely positioned to help reduce risks associated with BPSD, including the use of psychotropic medications. Training satisfaction was high, knowledge about BPSD increased, and attitudes improved. The DICE trainings prepared trainees to implement this intervention with 165 family caregivers. A follow-up survey will explore the real-world application of DICE, including barriers to its use and modifications made in communities across the state.

Abstract
Introduction By age 60, 60% of adults with Down syndrome (DS) have dementia. Detecting dementia in persons with intellectual disability (ID) can be challenging because their underlying cognitive impairment can confound presentation of dementia symptoms and because adults with ID may have difficulty reporting symptoms. The National Task Group Early Detection Screen for Dementia (NTG‐EDSD) was developed to aid detection of report of cognitive impairment in adults with ID. We implemented an educational curriculum using the NTG‐EDSD and evaluated the impact of the intervention on professional caregivers’ self‐assessed capacity to identify persons with ID and dementia. Methods We held five in‐person training sessions for professional caregivers of persons with ID, partnering with various managed care organizations and social services agencies. We assessed knowledge and attitudes at baseline; immediately after training; and 1 week, 1 month, and 6 months after training. Results A total of 154 direct care workers, case managers, health‐care providers, and other social services staff attended the trainings. Satisfaction with the NTG‐EDSD training was high; 94% of attendees agreed or strongly agreed that they could use the NTG‐EDSD with their clients. After training, attendees reported a marked increase in confidence in their ability to track various health circumstances and detect functional decline in their clients, although some gains were not sustained over time. As a result of the training, one managed care organization made the NTG‐EDSD a standard part of its assessment of adults with DS starting at age 40. Discussion Social services and health‐care professionals can learn to document signs of cognitive decline in adults with ID using the NTG‐EDSD. Attendees were highly satisfied with the training, experienced an increase in confidence in their care of persons with ID, and found the NTG‐ EDSD feasible to use. Because not all gains were sustained over time, booster trainings may be necessary.

Abstract
By combining DNA nanotechnology and high-bandwidth single-molecule detection in nanopipets, we demonstrate an electric, label-free hybridization sensor for short DNA sequences (<100 nucleotides). Such short fragments are known to occur as circulating cell-free DNA in various bodily fluids, such as blood plasma and saliva, and have been identified as disease markers for cancer and infectious diseases. To this end, we use as a model system an 88-mer target from the RV1910c gene in Mycobacterium tuberculosis, which is associated with antibiotic (isoniazid) resistance in TB. Upon binding to short probes attached to long carrier DNA, we show that resistive-pulse sensing in nanopipets is capable of identifying rather subtle structural differences, such as the hybridization state of the probes, in a statistically robust manner. With significant potential toward multiplexing and high-throughput analysis, our study points toward a new, single-molecule DNA-assay technology that is fast, easy to use, and compatible with point-of-care environments.

Abstract
The aim of this cohort study was to assess the risk of developing cancer, specifically leukaemia, tumours of the central nervous system and lymphoma, before the age of 15 years in children previously exposed to computed tomography (CT) in Germany. Data for children with at least one CT between 1980 and 2010 were abstracted from 20 hospitals. Cancer cases occurring between 1980 and 2010 were identified by stochastic linkage with the German Childhood Cancer Registry (GCCR). For all cases and a sample of non-cases, radiology reports were reviewed to assess the underlying medical conditions at time of the CT. Cases were only included if diagnosis occurred at least 2 years after the first CT and no signs of cancer were recorded in the radiology reports. Standardised incidence ratios (SIR) using incidence rates from the general population were estimated. The cohort included information on 71,073 CT examinations in 44,584 children contributing 161,407 person-years at risk with 46 cases initially identified through linkage with the GCCR. Seven cases had to be excluded due to signs possibly suggestive of cancer at the time of first CT. Overall, more cancer cases were observed (O) than expected (E), but this was mainly driven by unexpected and possibly biased results for lymphomas. For leukaemia, the SIR (SIR = O/E) was 1.72 (95 % CI 0.89-3.01, O = 12), and for CNS tumours, the SIR was 1.35 (95 % CI 0.54-2.78, O = 7). Despite careful examination of the medical information, confounding by indication or reverse causation cannot be ruled out completely and may explain parts of the excess. Furthermore, the CT exposure may have been underestimated as only data from the participating clinics were available. This should be taken into account when interpreting risk estimates.

Abstract
Patient participation in cancer clinical trials is low. Little is known about attitudinal barriers to participation, particularly among patients who may be offered a trial during an imminent initial oncology consult. The aims of the present study were to confirm the presence of proposed subscales of a recently developed cancer clinical trial attitudinal barriers measure, describe the most common cancer clinical trials attitudinal barriers, and evaluate socio-demographic, medical and financial factors associated with attitudinal barriers. A total of 1256 patients completed a survey assessing demographic factors, perceived financial burden, prior trial participation and attitudinal barriers to clinical trials participation. Results of a factor analysis did not confirm the presence of the proposed four attitudinal barriers subscale/factors. Rather, a single factor represented the best fit to the data. The most highly-rated barriers were fear of side-effects, worry about health insurance and efficacy concerns. Results suggested that less educated patients, patients with non-metastatic disease, patients with no previous oncology clinical trial participation, and patients reporting greater perceived financial burden from cancer care were associated with higher barriers. These patients may need extra attention in terms of decisional support. Overall, patients with fewer personal resources (education, financial issues) report more attitudinal barriers and should be targeted for additional decisional support.

Abstract
The quantum-mechanical tunnelling effect allows charge transport across nanometre-scale gaps between conducting electrodes. Application of a voltage between these electrodes leads to a measurable tunnelling current, which is highly sensitive to the gap size, the voltage applied and the medium in the gap. Applied to liquid environments, this offers interesting prospects of using tunnelling currents as a sensitive tool to study fundamental interfacial processes, to probe chemical reactions at the single-molecule level and to analyse the composition of biopolymers such as DNA, RNA or proteins. This offers the possibility of a new class of sensor devices with unique capabilities.

Abstract
AbstractCathodoluminescence measurements at cryogenic temperatures are reported on boron- and phosphorus-doped CVD-diamond films grown on silicon substrates. Boron and phosphorus concentrations were determined by SIMS measurements; for boron, they reached from unintentional background doping levels up to 3500 ppm. At increasing boron concentrations, the radiative recombination of boron bound excitons (BEto) at 5.22 eV photon energy systematically broadens and shifts down to 4.99 eV whereas the free exciton emission (FEto) disappears for 40 ppm and higher. In the phosphorus-doped films we observe new lines at 5.16 eV and 4.99 eV which we ascribe to TO- and (TO+Or)-phonon assisted transitions of an exciton bound to a shallow impurity other than boron, possibly phosphorus or a phosphorus-related shallow complex.

Abstract
OBJECTIVES The purpose of this study was to validate a new laboratory method to test all-ceramic systems with regard to the proportion of failures. METHODS Sixteen standardized mandibular molar crowns consisting of two different materials (IPS Empress, IPS e.max Press) were adhesively luted on CAD/CAM milled PMMA abutments (first lower molar, circular chamfer). All crowns were loaded applying an eccentric force in a Willytec chewing simulator (steel stylus, Ø 2.4 mm, 2 mm lateral movement from fossa to cuspal tip) with stepwise increase of the load (3, 5, 9 kg, 100,000 cycles each, 0.8 Hz) and simultaneous thermocycling (5°C/55°C×417 per phase). Another four crowns of each material were subjected to force measurements with a 3D force sensor during dynamic loading of each loading phase using two different lateral movements (from fossa to cusp and vice versa). RESULTS The cumulative forces for the three directions in space were much higher compared to the static load of the chewing simulator (maximal force at 3 kg 60 N, 5 kg 160 N, 9 kg 240 N). There was no statistically significant difference in the mean or maximal force between the two materials or two different lateral movements. During dynamic loading, no fractures occurred in the molar crowns made of IPS e.max Press, whereas 50% of the IPS Empress crowns showed failures (75% fractures and 25% chippings) (log-rank test p=0.002). Most of the Empress crowns fractured during the third loading phase (9 kg). CONCLUSIONS The forces that the dead weights exerted during dynamic loading were 2-3 times higher than those during static loading. None of the lithium disilicate ceramic molar crowns fractured, whereas half of the leucite reinforced molar crowns failed during dynamic loading.
