RESUMEN
Here, we report on the outcome of the 2nd International Danube Symposium on advanced biomarker development that was held in Vienna, Austria, in early 2018. During the meeting, cross-speciality participants assessed critical aspects of non-invasive, quantitative biomarker development in view of the need to expand our understanding of disease mechanisms and the definition of appropriate strategies both for molecular diagnostics and personalised therapies. More specifically, panelists addressed the main topics, including the current status of disease characterisation by means of non-invasive imaging, histopathology and liquid biopsies as well as strategies of gaining new understanding of disease formation, modulation and plasticity to large-scale molecular imaging as well as integrative multi-platform approaches. Highlights of the 2018 meeting included dedicated sessions on non-invasive disease characterisation, development of disease and therapeutic tailored biomarkers, standardisation and quality measures in biospecimens, new therapeutic approaches and socio-economic challenges of biomarker developments. The scientific programme was accompanied by a roundtable discussion on identification and implementation of sustainable strategies to address the educational needs in the rapidly evolving field of molecular diagnostics. The central theme that emanated from the 2nd Donau Symposium was the importance of the conceptualisation and implementation of a convergent approach towards a disease characterisation beyond lesion-counting "lumpology" for a cost-effective and patient-centric diagnosis, therapy planning, guidance and monitoring. This involves a judicious choice of diagnostic means, the adoption of clinical decision support systems and, above all, a new way of communication involving all stakeholders across modalities and specialities. Moreover, complex diseases require a comprehensive diagnosis by converging parameters from different disciplines, which will finally yield to a precise therapeutic guidance and outcome prediction. While it is attractive to focus on technical advances alone, it is important to develop a patient-centric approach, thus asking "What can we do with our expertise to help patients?"

STATEMENT OF PROBLEM: There are no recent data that describe the replacement rates of resin composite and dental amalgam restorations placed by US Navy dentists. Information is needed to provide the best possible care for our military personnel which would minimize the probability of dental emergencies, especially for those who are deployed. PURPOSE: The purpose of this study was to determine if the frequency of posterior restoration replacement in military personnel differed based on the type of restorative material utilized. METHODS AND MATERIALS: Data contained in dental records in an observational study (retrospective cohort) were evaluated to identify resin composite and dental amalgam restorations placed by navy dentists in posterior teeth. The status of all erupted, unerupted, missing, and replaced teeth was documented. The type and condition of all existing restorations were recorded for each posterior tooth. Investigators reviewed 2921 dental records, and of those, 247 patients met the criteria for inclusion in the study. A total of 1050 restorations (485 resin composite and 565 amalgam) were evaluated. RESULTS: A Cox proportional hazards model was adjusted for number of tooth surfaces restored, caries risk, and filled posterior surfaces at initial exam. The overall rate of replacement for all restorations in the sample was 5.7% during the average 2.8-year follow-up. No significant elevation of risk for restoration replacement existed when comparing resin composite and amalgam. Both the number of restored surfaces and caries risk status were independent risk factors for replacement. When restoring multisurface cavity preparations, providers placed amalgams by an approximate 2:1 ratio over resin composites for this study population. CONCLUSION: The results for this study show that no difference existed in the rate of replacement for amalgam vs resin composite. When restorations increased from just a single occlusal surface to additional surfaces, the rate of replacement was elevated and statistically significant for both materials. A higher caries risk status was also significant in elevating replacement rates for both materials.

A 3-year prospective study was designed to evaluate sealants in preventing the formation and progression of caries in a young adult military population. United States Navy dentists performed dental examinations on recruits being in-processed at the Naval Training Center, San Diego, California. Contralateral molar pairs (same arch) without caries or restorations were selected. Occlusal decalcification and lesions limited to enamel were also eligible, but teeth with proximal decalcification were disqualified. The sample consisted of 860 molar pairs in 529 Navy recruits, each contributing one or two pairs. Required annual dental examinations provided follow-up data, with results being recorded on postcards that were mailed back to the investigator. Yearly response rates were as follows: 1 year, 62.2% (483 molar pairs); 2 year, 47.8% (378 molar pairs); and 3 year, 41.4% (317 molar pairs). The response rate for pairs having at least one observation during the 3-year follow-up was 72.6% (563 molar pairs), with a caries conversion rate of 1.2% (7 teeth) on sealed teeth and 5.3% (32 teeth) on control teeth, yielding 35 discordant molar pairs on 33 recruits (30 on control teeth and 5 on sealed teeth) (p < 0.0001). These results confirm the efficacy of sealants in significantly reducing the rate caries in a young adult military population.

The purpose of this study was to determine the incidence of dental emergency visits for Marine Corps personnel ashore during Operations Desert Shield/Storm. We investigated the period of August 18, 1990, through April 19, 1991, during which 16 dental treatment facilities treated 4,776 dental emergencies in Marine Corps personnel. All dental treatment facilities maintained log books of dental treatment rendered, from which data were obtained. For the 35 weeks, a rate of 100.5 emergencies/1,000 Marines was calculated. The range, on a per week basis, was 1.4 to 4.6 emergencies/1,000 Marines. Caries, defective restorations, and endodontic complaints accounted for 54.3% of emergency visits.

Phased dentistry (PD) is a philosophy of managed oral health care that emphasizes an orderly approach to dental risk assessment, prevention, and disease management. PD is divided into two stages. Phase I (PH1) care is intended to eliminate all conditions that may produce a dental emergency within 12 months. PH1 care is directed primarily to recruits and apprentice training students. Phase 2 (PH2) care strives to attain and maintain optimal oral health for Navy and Marine Corps personnel after their initial training period and throughout their military career. The purpose of this study was to evaluate the feasibility of introducing PH1 into a recruit dental treatment facility. Data were obtained at Naval Dental Center (NDC), Orlando from 4,571 recruit dental patients who were in-processed and completed recruit training between May 27 and October 1, 1993. The incoming operational dental readiness (ODR) of recruits during the PD trial was 28.5%, whereas the ODR of graduating recruits was 85.8%. During this same period there was a 34% increase in completed dental treatments per provider full time equivalent. Although dramatic increases in ODR and productivity were noticed during PD, other variables may have contributed to these results.

The purpose of this study was to determine the incidence and distribution of dental emergencies in Marine Corps personnel. Dental emergencies were recorded from June 1989 to June 1990 for personnel who were in garrison, deployed, or participating in field exercises. A standardized data-collection form was distributed to participating Marine Corps dental clinics and to dental officers assigned to Marine Corps deployments or field exercises. A total of 890 dental emergency visits by Marines were recorded: 699 for Marines while in garrison, 136 while deployed, and 55 while participating in field exercises. Tooth/restoration fracture without pulpal involvement and pericoronitis were the most frequent diagnoses at emergency visits in each of the three environments. The mean incidence rate of dental emergencies per 1,000 person-years for deployed Marine Corps personnel was 57.2.

Numerous literature references have suggested increased risk for localized alveolar osteitis associated with female gender, use of oral contraceptives, and point in menstrual/contraceptive cycle. However, the available information has not been systematically considered with the intent to accurately estimate the magnitude of these effects. The present review suggests that under certain conditions, some of which may be avoidable, females may have at least a two to threefold increase in osteitis risk compared with males. It appears that this greater risk may be reduced by considering hormonal cycles when scheduling elective exodontia.

Advantages and disadvantages of the estimation of the mass and number fibrous dusts concentrations are discussed. By using the reference phase contrast microscopic method (1) the data of interlaboratory comparative measurements of MMMF (man-made mineral fibres/density/f.mm-2) have been got and are presented. Total mass dust concentrations and number concentrations of MMMF and/or asbestos fibres are compared. The consequent measurements were made in the same time intervals and in the same workplaces. In conclusion both measuring methods are critically evaluated and their results are compared with the prescribed MAC-values. Presented results are of use when deciding what method with respect to the kind of fibrous dust and to the working operation should be chosen.
