Association between Dental Caries and Influenza Infection in Children: A Japanese Nationwide Population-Based Study

Dental caries is the most common chronic childhood disease. Recent studies have suggested that dental caries harbor respiratory infections in adults. We investigated the association between dental caries and influenza in children. In this study, 42,812 children aged 2.5 years, 38,540 children aged 5.5 years, and 34,124 children aged 10 years were included in the analysis from the Longitudinal Survey of Newborns in the 21st Century in Japan, which targeted all children born during a certain period in 2001. We used information on dental caries treated at hospitals and clinics in the past year as exposure and influenza as outcome during the observation periods (1.5–2.5, 4.5–5.5, and 9–10 years of age). We performed a log-binomial regression analysis, adjusting for potential confounders, and stratified analysis according to previous dental caries status. The presence of dental caries increased the incidence of influenza in all three target ages compared with the absence of dental caries. The incidence of influenza increased with the presence of current dental caries, regardless of the presence of past dental caries. These associations were observed irrespective of household income. Early detection and treatment of dental caries may reduce the risk of influenza in children.

Abstract Background: Dental caries is associated with Biological, behavioral, socioeconomic, and environmental factors; however, socioeconomic status is a distal determinant of dental caries development that modulates exposure to risk and protective factors. This study aimed to analyze the factors associated with the distribution and concentration of oral diseases in a population-based study in Brazil.Methods: This is a quantitative, analytical, cross-sectional study based on secondary data from the SB São Paulo 2015 epidemiological survey. A total of 17,560 subjects were included. The concentration of oral disease in the population was estimated by the oral disease burden (ODB) variable. The ODB consists of four components: dental caries; tooth loss; need for dental prosthesis and periodontal condition. Thus, the total score on the ODB could vary between 0 and 4, with the highest score indicating the worst possible situation. ODB was analyzed in multivariate negative binomial regression, and multivariate binary logistic regression analysis. The following demographic data were included as independent variables: age group, skin color, socioeconomic data, and family income.Results: ODB was present in 86.9% of the sample. Negative multivariate binomial regression showed a statistically significant relationship (p<0.005) between ODB and all variables analyzed (skin color, family income, education, OIDP results and age range). The adjusted multivariate binary logistic regression showed that the individuals most likely to have at least one component of ODB were nonwhite (25.5%), had a family income of up to R$ 1,500.00 / month (19.6%), had only completed primary education (19.1%), and reported that their oral health had an impact on their daily activities (57.6%). Elderly individuals were two times more likely than adolescents to have an ODB component.Conclusions: ODB is associated with factors related to social inequality. Adults and elderly individuals had the highest cumulative number of ODB components.

SUMMARYThe incidence of childhood respiratory infections in Greenland is among the highest globally. We performed a population-based study of 352 Greenlandic children aged 0–6 years aiming to describe rates and risk factors for carriage of four key bacteria associated with respiratory infections, their antimicrobial susceptibility and inter-bacterial associations. Nasopharyngeal swabs were tested for Streptococcus pneumoniae grouped by serotypes included (VT) or not included (NVT) in the 13-valent pneumococcal conjugate vaccine, non-typable Haemophilus influenzae (NTHi), Staphylococcus aureus and Moraxella catarrhalis. S. pneumoniae was detected from age 2 weeks with a peak carriage rate of 60% in 2-year-olds. Young age and having siblings attending a daycare institution were associated with pneumococcal carriage. Overall co-colonization with ⩾2 of the studied bacteria was 52%. NTHi showed a positive association with NVT pneumococci and M. catarrhalis, respectively, M. catarrhalis was positively associated with S. pneumoniae, particular VT pneumococci, whereas S. aureus were negatively associated with NTHi and M. catarrhalis. Nasopharyngeal bacterial carriage was present unusually early in life and with frequent co-colonization. Domestic crowding increased odds of carriage. Due to important bacterial associations we suggest future surveillance of pneumococcal conjugate vaccine's impact on carriage in Greenland to also include other pathogens.

Abstract We identify the yearly trends in the prevalence of various ocular traumas in the Republic of Korea, and the effects of Covid-19. We recorded the yearly numbers of patients diagnosed with hyphema and those who underwent open reduction surgery because of orbital blowout fracture (BOF), primary closure of the cornea or sclera (PCCS), or intraocular foreign body (IOFB) removal. The incidence of closed globe injuries has decreased significantly over the past 10 years, while that of open globe injuries has not. The patients aged ≥ 60 years showed a significant increase in BOF surgery. Regarding the trend in PCCS, while other age groups showed significant decreases, the population aged ≥ 60 years did not. In addition, the population aged ≥ 60 years showed a significant increase in the incidence of IOFB. When the 2020 data were compared with those of 2019, hyphema evidenced the largest decrease (27.02%), especially in those aged < 20 years (54.33%). In terms of both BOF and IOFB, those aged < 20 years showed the largest decreases (28.85% and 47.93% respectively). In the Covid-19 era, ocular trauma fell markedly in those aged < 20 years, perhaps because of school closures and reductions in outdoor activities.

AbstractObjectiveThe present study was undertaken to assess the status of vitamins A and E (VA and VE, respectively) and their main determinants in Tunisian children.DesignCross-sectional population-based study.SettingKasserine Governorate in the centre west of Tunisia.SubjectsA total of 7407 children attending the first grade of elementary school were included. VA and VE were assessed by HPLC.ResultsThe prevalence of moderate VA deficiency (VAD; <0·70 μmol/l) was 2·3 % and VE deficiency (VED; <6·97 μmol/l) was 5·4 %. Low status in VA (0·70–1·05 μmol/l) and VE (6·97–11·61 μmol/l) was observed in 17 % and 20·2 % of children, respectively. No child exhibited severe VA or VE deficiency (<0·35 and <2·32 μmol/l, respectively). The main predictors of VAD were advanced age (OR = 1·65; 95 % CI 1·13, 2·41;P= 0·05) and sickness within the past 2 weeks (OR = 1·51; 95 % CI 1·09, 2·09;P= 0·01). Predictors of VED were living in the peri-urban region (OR = 1·60; 95 % CI 1·28, 2·01;P< 0·001) and sickness within the past 2 weeks (OR = 0·75; 95 % CI 0·60, 0·94;P= 0·01).ConclusionsModerate VAD and VED were uncommon in Tunisian children. However, low status in VA and/or VE remains frequent. A reinforcement of the national strategies for children's nutrition and health is needed, particularly in disadvantaged regions. Supplementation of VA and VE is not necessary in Tunisia, but food fortification may be beneficial.
