Abstract Background The relationship between dental caries and periodontal disease is still controversial. The objective of this study was to explore the relationship between different types of caries and periodontal disease severity in middle-aged and elderly people in China. Methods The study population consisted of 4407 middle-aged and 4117 elderly subjects. Caries were divided into the following three types: type A, crown caries; type B, lesions involving both the crown and root, representing mixed-type caries; and type C, root caries. These three types together represent the overall caries situation, which we call type ABC. Caries were quantitated by decayed and filled teeth (DFT index). Periodontitis was evaluated by clinical attachment loss. Results Middle-aged people with periodontitis had a significant association with DFT type B (OR: 1.21, 95% CI 1.17–1.25) and type C (OR: 1.40, 95% CI 1.24–1.56). Elderly people with periodontitis had a significant association with DFT type C (OR: 1.28, 95% CI 1.21–1.35). Conclusions In China, caries types B/C were positively correlated with periodontitis in the middle-aged group, and only caries type C was positively correlated with periodontitis in the elderly group.

The Relationship

Abstract Background: To explore the relationship between different types of caries and periodontal disease severity in middle-aged and elderly people in China. Methods: The study population consisted of 4,387 middle-aged and 3,225 elderly subjects. Caries was divided into three types: type A, crown caries; type B, lesions involving both the crown and root, which represents mixed type; and type C, root caries. These three types together represent the overall caries situation, which we call type ABC. Caries was quantitated by decayed and filled teeth (DFT index). Periodontitis was evaluated by clinical attachment loss.Results: Middle-aged people with periodontitis had a significant association with DFT of type ABC (OR: 1.09, 95% CI: 1.06‐1.11), type A (OR: 1.05, 95% CI: 1.02‐1.08), type B (OR: 1.20, 95% CI: 1.16-1.28) and type C (OR: 1.36, 95% CI: 1.15-1.60). Elderly people with periodontitis had a significant association with DFT of type ABC (OR: 1.05, 95% CI: 1.03-1.07), type B (OR: 1.07, 95% CI: 1.05-1.10) and type C (OR: 1.30, 95% CI: 1.19-1.42)，but not with type A.Conclusions: Different types of caries in middle-aged people, the overall caries and caries types involving the root surface in elderly people were significantly associated with periodontal disease severity.

AbstractLense-Thirring QPO model is a promising model to explain QPO phenomena (Ingram et al. (2009)). In this model the QPO results from Lense-Thirring precession of a optical translucent inner hot flow in a truncated disc geometry. Now we check this model with different types QPO (see (Belloni et al. (2011)) for a recent review) of black hole transient (BHT) GX 339-4 2010 outburst and suggest type C QPOs are mainly coincident with this model prediction while type B QPOs are not.

The Relationship

This work was try to study the number and types of hydrogen bonds (H-bonds) formed in hindered phenol AO-70/nitrile butadiene rubber (NBR) composites and their contributions to the damping properties by molecular dynamic (MD) simulation and experimental methods. MD simulation results showed that there were four types of H-bonds, namely, type A (AO-70) –OH...NC– (NBR) H-bonds in AO-70/NBR composites, type B (AO-70) –OH...O=C– (AO-70) H-bonds, type C (AO-70) –OH...OH–(AO-70) and D (AO-70) –OH...O–C– (AO-70) H-bonds, what's more, type A and type B H-Bonds formed more easily than others. Fourier transform infrared spectroscopy (FTIR) confirmed the existence of H-bonds. Meanwhile, the AO-70/NBR composites with AO-70 content of 109 phr had the largest number of H-bonds, smallest fractional free volume (FFV) and resulting in the optimistic damping performance of the composites.

Objective This study aims to explore the relationship between sedentary behavior and the diabetes mellitus prevalence of middle-aged and elderly people. Methods  we conduct a questionnaire survey and physical examination for a total of 3,000 middle-aged and elderly people (≥45 years old) ,analysing by he software of  SPSS21.0 and Stata12.0. Results The logistic regression analysis shows that the risk of diabetes is 1.617 (95% CI, 0.762-1.789, P <0.05) at 2-4h, 4-6h, 6-8h, ≥8h, = 0.003), 1.235 (95% CI, 0.818-1.865, P = 0.034), 3.420 (95% CI, 2.241-5.218, P = 0.000), 5.014 (95% CI, 3.049-8.247, P = 0.000). With each additional one-hour sedentariness the risk of diabetes increases by 23% (OR1.23, 95% CI 1.18-1.29, p <0.0001). Conclusions The sedentary behavior is an independent risk factor for diabetes. The prevalence of diabetes is gradually increasing with the increase of sedentary time, which indicates the longer sedentary time, the higher prevalence of diabetes.

The study objective was to investigate prevalence and determinants of current Helicobacter pylori infection in an asymptomatic population of middle-aged to elderly people. A cross-sectional study was conducted among 337 participants of a general education programme of the University of Ulm aged 50–85 years. Prevalence of infection as determined by means of the [13C]urea breath test was 34·8% (95% CI 29·6–40·3%) ; overall, 33·8% (95% CI 23·0–46·0) in the age group 50–59 years, 32·4% (95% CI 25·4–39·9) in the age group 60–69 years and 41·0% (95% CI 30·0–52·7) in the age group 70–85 years. Duration of school education of the father, sharing a bed with parents or siblings during childhood, and the area in which participants had grown up were independent determinants of current infection status in a multivariable analysis. We conclude that the prevalence of current H. pylori infection in healthy elderly subjects may not be as high as seroprevalence studies have suggested. Socioeconomic characteristics of childhood living conditions appear to be important determinants of infection status even at older age.

The Relationship

The aim of the study was to examine the relationship between age and intelligence and scores on the Rivermead Perceptual Assessment Battery (RPAB) in elderly subjects. A series of 100 normal elderly people were assessed in their own homes on the RPAB. Age was found not to affect performance on most RPAB tests but intelligence had a greater effect. Few significant differences were found between the performance of elderly subjects and the younger group from whom the test norms were derived. The RPAB was found to be suitable for use with elderly subjects.
