Background: Regular inspection of the oral cavity is required for prevention, early diagnosis and risk reduction of oral- and general health-related problems. Assessments to inspect the oral cavity have been designed for non-dental healthcare professionals, like nurses. The purpose of this systematic review was to evaluate the content and the measurement properties of oral health assessments for use by non-dental healthcare professionals in assessing older peoples’ oral health, in order to provide recommendations for practice, policy, and research. Methods: A systematic search in PubMed, EMBASE.com, and Cinahl (via Ebsco) has been performed. Search terms referring to ‘oral health assessments’, ‘non-dental healthcare professionals’ and ‘older people (60+)’ were used. Two reviewers individually performed title/abstract, and full-text screening for eligibility. The included studies have investigated at least one measurement property (validity/reliability) and were evaluated on their methodological quality using “The Consensus-based Standards for the selection of health Measurement Instruments” (COSMIN) checklist. The measurement properties were then scored using quality criteria (positive/negative/indeterminate). Results: Out of 879 hits, 18 studies were included in this review. Five studies showed good methodological quality on at least one measurement property and 14 studies showed poor methodological quality on some of their measurement properties. None of the studies assessed all measurement properties of the COSMIN. In total eight oral health assessments were found: the Revised Oral Assessment Guide (ROAG); the Minimum Data Set (MDS), with oral health component; the Oral Health Assessment Tool (OHAT); The Holistic Reliable Oral Assessment Tool (THROAT); Dental Hygiene Registration (DHR); Mucosal Plaque Score (MPS); The Brief Oral Health Screening Examination (BOHSE) and the Oral Assessment Sheet (OAS). Most frequently assessed items were: lips, mucosa membrane, tongue, gums, teeth, denture, saliva, and oral hygiene. Conclusion: Taken into account the scarce evidence of the proposed assessments, the OHAT and ROAG are most complete in their included oral health items and are of best methodological quality in combination with positive quality criteria on their measurement properties. Non-dental healthcare professionals, policymakers and researchers should be aware of the methodological limitations of the available oral health assessments and realize that the quality of the measurement properties remains uncertain.
Background: To assess the prevalence of chronic lymphedema and trismus in patients > 6 months after head and neck cancer (HNC) treatment, and to explore how the severity of these conditions correlates with body image and quality of life. Methods: The cross-sectional sample included 59 patients, treated for HNC between six months to three years ago. Physical measurements were performed to assess the presence of external lymphedema and trismus (<36 mm). Furthermore, participants completed two questionnaires regarding body image (BIS) and quality of life (UW-QoL V4). Results: Lymphedema prevalence was 94.1% (95% CI 0.86–0.98), with a median severity score of 9 (range 0–24). Trismus prevalence in this sample was 1.2%. The median BIS score was 2, indicating a positive body image. The UW-QoL score showed a good QOL with a median of 100. Only the domain of saliva and overall related health had a lower median of 70 and 60, respectively. There was no correlation between lymphedema and body image (r = 0.08, p = 0.544). Patients with higher lymphedema scores reported poorer speech with a moderate correlation (r = −0.39, p = 0.003). Conclusion: Lymphedema is a highly prevalent, but moderately severe late side-effect of HNC with a limited impact on quality of life domains except for speech, in our cohort.
Non-invasive, rapid, on-site detection and identification of body fluids is highly desired in forensic investigations. The use of fluorescence-based methods for body fluid identification, have so far remain relatively unexplored. As such, the fluorescent properties of semen, serum, urine, saliva and fingermarks over time were investigated, by means of fluorescence spectroscopy, to identify specific fluorescent signatures for body fluid identification. The samples were excited at 81 different excitation wavelengths ranging from 200 to 600 nm and for each excitation wavelength the emission was recorded between 220 and 700 nm. Subsequently, the total emitted fluorescence intensities of specific fluorescent signatures in the UV–visible range were summed and principal component analysis was performed to cluster the body fluids. Three combinations of four principal components allowed specific clustering of the body fluids, except for fingermarks. Blind testing showed that 71.4% of the unknown samples could be correctly identified. This pilot study shows that the fluorescent behavior of ageing body fluids can be used as a new non-invasive tool for body fluid identification, which can improve the current guidelines for the detection of body fluids in forensic practice and provide the robustness of methods that rely on fluorescence.

The continuous monitoring of health indicators in biofluids such as sweat, saliva, blood, and urine has great potential for preventive medicine. Techniques that continuously monitor biomarkers still remain a major technological challenge. Recently, a concept of dynamic biosensing was published that is based on mediator particles. Such mediator particles exhibit rapid switching between a bound and unbound state during interaction with a probing structure to which they are connected through a molecular tether (like a balloon on a string). Although the concept of using mediator particles for dynamics biosensing is very promising, the used detection method is not a viable solution as it is not miniaturizable. We propose to use a photonic ring resonator (RR) or Mach-Zender interferometer (MZI) as the probing structure in combination with a highly miniaturizable readout scheme. In this project, we perform preliminary experiments to prove that this photonic approach can be used for the detection of the mediator particles tethered to the photonic waveguide. To bridge the gap with the practical application by health professionals, we will enrich the envisioned solution through OnePlanet's OpenEd program. OpenEd aims to share technology and innovations (e.g. prototypes) with educational institutes (MBO, HBO) that want to further innovate their courses or work methods, such that current and future professionals are well prepared to work with new (digital) technologies. By presenting our use-case as a 'challenge' to teachers, students and practitioners, OpenEd also allows enriching the use-case by involving (future) health professionals that can provide feedback on - or further investigation of - the practical application of our new technology from the health professional's perspective.
