Investigating correlation of faecal indicator bacteria and potential pathogenic fungi on Dublin beaches in the interest of public health

Sandy beaches are usually the preferred location for leisure activities but may pose a risk to public health in particular to children, the elderly and immuno compromised individuals Beach sand and marine water may be a reservoir of opportunistic and pathogenic microbes, as well as faecal indicator bacteria (that influence the bathing water quality status. The growth and the proliferation of microbes in beach sand and water are not restricted to bacteria but include also different groups of fungi such as potentially pathogenic and allergenic moulds, yeasts and dermatophytes Currently, no clear guidance about pathogenic fungi levels in relation to public health is available for these environments.info:eu-repo/semantics/publishedVersio

From ‘every man for himself’, via collaboration, paving the way to cooperation in education

In deze bijdrage wordt onderbouwd dat gebrek aan continuïteit in het huidige (passende) onderwijs funest is voor samenwerking in de onderwijsketen. Die samenwerking vraagt om goede afspraken over de rollen tussen de partners in die keten en daar mankeert het een en ander aan omdat organisatorische maatregelen alleen ontoereikend zijn. Coöperatief werken is nodig om continuïteit, duurzaamheid en kwaliteit te kunnen garanderen.In this contribution, the lack of continuity in contemporary inclusive education practices is postulated as detrimental for collaboration in education. Collaboration requires good agreements about the roles of all partners involved which turns out to be insufficient in case only organizational measures are launched. Hence, cooperation is demanded to guarantee continuity, sustainability and quality in educatio

Incidence of peri-implant mucositis and peri-implantitis in patients with a maxillary overdenture:A sub-analysis of two prospective studies with a 10-year follow-up period

Background: Though studies on maxillary overdentures show satisfying results on implant survival, patient-related outcomes and prosthetic complications, the epidemiology of peri-implant diseases in this specific group of patients has hardly been reported. While the general patient-level prevalence of peri-implant mucositis and peri-implantitis are estimated at similar to 45% and similar to 20%, respectively, the risk of developing these diseases within a specific period is less dear. To fully appreciate the epidemiology of peri-implant diseases, more long-term data on incidence of peri-implant diseases are needed. Purpose: The purpose of this sub-analysis of two prospective studies was to assess the incidence of peri-implant mucositis and peri-implantitis in fully edentulous patients with implant-retained maxillary overdentures during a 10-year follow-up period. Materials and Methods: One hundred and sixteen patients treated with implant-supported maxillary overdentures were available from two clinical trials. Data on biological complications, clinical and radiographical parameters were collected for 106 patients at 5-year, for 82 patients at 10-year follow-up. The incidence was calculated following the consensus of the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions. Extent and severity then were calculated to enable an appropriate epidemiological description of peri-implantitis. Results: The patient-level incidence of peri-implant mucositis was 37.7% after 5 years and 64.6% after 10 years whereas the patient-level incidence of peri-implantitis was 10.4% after 5 years and 19.5% after 10 years. After 10 years, the extent of peri-implant mucositis and peri-implantitis is 52.8% and 43.8%, respectively. In terms of severity, 26.5% of all affected implants suffered from >3 mm bone loss and 17.6% of all affected implants was lost. Conclusion: Three of five fully edentulous patients with implant-supported maxillary overdentures experience peri-implant mucositis after 10 years. Peri-implantitis occurs in one of five patients after 10 years. In spite of these incidence rates, implant survival remains high

Maxillary overdentures supported by four or six implants in the anterior region:5-year results from a randomized controlled trial

OBJECTIVE: To compare a four‐ and six‐implant maxillary overdenture after an observation period of 5 years. MATERIAL AND METHODS: Fifty subjects with functional problems concerning their maxillary denture, who had ample bone volume in the anterior region to place four or six implants, were included and randomly assigned to either group. Implant and overdenture survival, clinical performance, marginal bone loss and patient satisfaction were assessed. RESULTS: Forty‐six patients completed the 5‐year follow‐up. One implant failed in the six implants group (99.2% survival) and none in the four implants group (100% survival). No overdentures had to be replaced during the observation period and the number of complications was limited. Clinical function was good, with no difference in clinical parameters between the groups. Mean marginal bone resorption was 0.50 ± 0.37 and 0.52 ± 0.43 mm in the four and six implant group respectively. CONCLUSION: In patients with functional complaints of their maxillary denture, bar‐supported overdentures on four implants in the anterior maxillary region were not inferior to overdentures supported by six implants after 5 years of function. Implant survival and patient satisfaction were high, clinical parameters favourable, bone loss and complications to the denture were minor in both groups (Clinical trial registration number: NTR2969)
