RESUMO

OBJECTIVES: This systematic review aimed to evaluate the efficacy of supportive care provision, frequency and protocol in patients treated for peri-implantitis, as reported in prospective and retrospective studies of at least 3-years duration. MATERIALS AND METHODS: A systematic search of three electronic databases was undertaken up to 21 July 2022 and supplemented by hand-search to identify studies that included participants treated for peri-implantitis and followed for at least 3 years. Owing to high heterogeneity, a meta-analysis was not appropriate, and therefore, data and risk of bias were explored qualitatively. PRISMA guidelines for reporting were followed. RESULTS: The search identified 2596 studies. Of 270 records selected during screening, 255 were excluded through independent review and 15 studies (10 prospective and 5 retrospective, with at least 20 patients) were retained for qualitative assessments. Study designs, population characteristics, supportive care protocols and reported outcomes varied markedly. Thirteen of the 15 studies had low risk of bias. Supportive peri-implant care (SPIC) following different surgical peri-implantitis treatment protocols and with recall intervals varying between 2 months and annually resulted in peri-implant tissue stability (no disease recurrence or progression) ranging from 24.4% to 100% at patient level and from 28.3% to 100% at implant level. Sevenhundred and eighty-five patients with 790 implants were included in this review. CONCLUSIONS: Provision of SPIC following peri-implantitis therapy may prevent disease recurrence or progression. Insufficient evidence is available to identify (i) a specific supportive care protocol for secondary prevention of peri-implantitis, (ii) the effect of adjunctive local antiseptic agents in the secondary prevention of peri-implantitis and (iii) the impact of frequency of supportive care measures. Prospective, randomised, controlled studies designed to evaluate supportive care protocols are needed in future.

RESUMO

Widespread vaccination in pursuit of herd immunity has been recognized as the most promising approach to ending the global pandemic of coronavirus disease 19 (COVID-19). The vaccination of children and adolescents has been extensively debated and the first COVID-19 vaccine is now approved in European countries for children aged > 12 years of age. Our study investigates vaccination hesitancy in a cohort of German secondary school students. We assessed 903 students between age 9 and 20 in the period between 17 May 2021 and 30 June 2021. 68.3% (n = 617) reported intention to undergo COVID-19 vaccination, while 7% (n = 62) did not want to receive the vaccine and 15% (n = 135) were not yet certain. Age and parental level of education influenced COVID-19 vaccine hesitancy. Children under the age of 16 as well as students whose parents had lower education levels showed significantly higher vaccine hesitancy.  Conclusion: Identifying subsets with higher vaccination hesitancy is important for targeting public information campaigns in support of immunization. What is Known: • The willingness to receive COVID-19 vaccination among adults in Europe is about 70%, but data for children and adolescents is lacking. • The lack of immunization in younger cohorts represents a significant barrier to achieving herd immunity, and also leaves children and adolescents vulnerable to acute and long-term morbidity from natural COVID-19 infections. What is New: • Intention-to-vaccinate among children and adolescents is high (~ 70%); conversely, vaccination hesitancy is low. • Age and parental level of education influenced COVID-19 vaccine hesitancy among children and adolescents.

RESUMO

PURPOSE: The COVID-19 pandemic affects students in a myriad of different ways. Our prospective, longitudinal study in a cohort of students in Hannover, Germany explores behavioral patterns during escalating COVID-19 restrictions. METHODS: In total, 777 students between the age of 9 and 20 were assessed for their activity engagement, travel patterns, and self-assessed compliance with protective recommendations at six time points between June 2020 and June 2021 (3,564 observations) and were monitored for severe acute respiratory syndrome coronavirus 2 infection by nasal swab polymerase chain reaction and serum antibody titers. RESULTS: Activity engagement decreased, but self-assessed compliance with measures such as mask wearing and social distancing was stable during escalating restrictions. Although we found no sex difference during the summer break, when incidence was lowest, females engaged in a higher variety of activities than males for all other time points. Older students engaged in more activities and self-assigned themselves lower compliance values than younger ones. Greater involvement in different activities was seen in households which traveled more frequently. Infection rate in our cohort was low (0.03% acute infections, 1.94% positive seroprevalence). DISCUSSION: Our study supports the view that, overall, students show high compliance with COVID-19 recommendations and restrictions. The identification of subsets, such as female and older students, with higher risk behavioral patterns should be considered when implementing public information campaigns. In light of the low infection rate in our cohort, we conclude that in-person learning can occur safely if extensive protective measures are in place and the incidence in the general population remains moderate.
