Incidence and risk factors of tuberculosis among the elderly population in China: a prospective cohort study.

Background: China is facing challenges of the shifting presentation of tuberculosis (TB) from younger to elderly due to an ageing population, longer life expectancy and reactivation disease. However, the burden of elderly TB and influence factors are not yet clear. To fill the gap, we generated a cohort study to measure the magnitude of TB incidence and associated factors among the elderly population aged 65 years and above in China.

Adsorption of Cadmium Ions from an Aqueous Solution on a Highly Stable Dopamine-Modified Magnetic Nano-Adsorbent.

Magnetic nanomaterials were functionalized with dopamine hydrochloride as the functional reagent to afford a core-shell-type FeO modified with polydopamine (FeO@PDA) composite, which was used for the adsorption of cadmium ions from an aqueous solution. In addition, the effects of environmental factors on the adsorption capacity were investigated. Furthermore, the adsorption kinetics, isotherm, and thermodynamics of the adsorbents were discussed.

Association between elevated blood glucose level and non-valvular atrial fibrillation: a report from the Guangzhou heart study.

Background: To estimate the prevalence of elevated blood glucose level (EBG, including type 2 diabetes mellitus and impaired fasting glucose), and its association with non-valvular atrial fibrillation (NVAF) in Guangzhou, China.

Methods: The population-based follow-up Guangzhou Heart Study collected baseline data from July 2015 to August 2017 among 12,013 permanent residents aged > 35 from 4 Guangzhou districts. Two streets (Dadong and Baiyun) in the Yuexiu District, and one street (Xiaoguwei) and two towns (Xinzao and Nancun) in the Panyu District were chosen as representative of urban and rural areas, respectively.

[Effectiveness of 3 different methods in prevention of dental caries in permanent teeth among children].

Purpose: To compare the effectiveness of fluoride vanish, fluoride foam, pit and fissure sealant with fluoride in prevention of dental caries, and investigate appropriate approach to prevent dental caries at schools.

Methods: A randomized controlled clinical trial with 4 parallel groups was conducted. Totally 1016 children from 4 schools and 33 classes with a mean age of 7 to 8 years were included.

[A study on the combination of Nance arch and TPA in the use of straight-wire arch orthodontic treatment].

Purpose: To evaluate the effect of combination of Nance and TPA on the use of MBT appliance to treat Class II division I malocclusion.

Methods: Nineteen cases of Class II division I malocclusion, aged from 12 to 16 years, underwent Nance arch and TPA in the use of MBT appliance to reinforce molar anchorage. Cephalometric analysis and model measurements were conducted and compared before and after treatment using SAS8.
