Does public pension impact migrant workers’ nutrition: evidence from urban pension insurance in China / A previdência pública impacta a nutrição de trabalhadores migrantes: evidências do seguro de pensão urbana na China

Based on the data of “employment and food demand of urban migrant workers”, this paper empirically analyzed the impact of urban pension insurance on the nutritional intake structure of migrant workers. The results showed that participating in urban pension insurance can change the nutritional intake structure of migrant workers. Additionally, fat and protein replace carbohydrate as the main nutrition sources for migrant workers. After controlling the income and labor intensity of migrant workers and other factors, urban pension insurance has a positive effect on the intake of fat and protein of migrant workers for they increase by 13.5% and 8.8% respectively. There is no significant effect on the intake of carbohydrates of migrant workers. The calorie intake of migrant workers increases by 6.8% accounting for the change of nutritional intake structure. Endogenous and robustness tests showed that the above conclusions are robust. Heterogeneity analysis showed that there is no significant difference in the effect of urban pension insurance on calorie intake of migrant workers in different income levels and age groups.

Hand, foot and mouth disease and herpangina caused by enterovirus A71 infections: a review of enterovirus A71 molecular epidemiology, pathogenesis, and current vaccine development.

Enterovirus A71 (EV-A71) infections are one of the main etiological agents of hand, foot and mouth disease (HFMD) and herpangina worldwide. EV-A71 infection is a life-threatening communicable disease and there is an urgent global need for the development of vaccines for its prevention and control. The morbidity rate of EV-A71 infection differs between countries. The pathogen's genetic lineages are undergoing rapid evolutionary changes. An association between the occurrence of EV-A71 infection and the circulation of different genetic strains of EV-A71 virus has been identified around the world. In this review, we present and discuss the molecular epidemiology and pathogenesis of the human disease caused by EV-A71 infection, as well as current prospects for the development of an EV-A71 vaccine.

Systemic antibiotics in the treatment of aggressive periodontitis. A systematic review and a Bayesian Network meta-analysis.

AIM: The aim of this study was to assess the effect of systemic antibiotic therapy on the treatment of aggressive periodontitis (AgP). METHODS: This study was conducted and reported in accordance with the PRISMA statement. The MEDLINE, EMBASE and CENTRAL databases were searched up to June 2014 for randomized clinical trials comparing the treatment of subjects with AgP with either scaling and root planing (SRP) alone or associated with systemic antibiotics. Bayesian network meta-analysis was prepared using the Bayesian random-effects hierarchical models and the outcomes reported at 6-month post-treatment. RESULTS: Out of 350 papers identified, 14 studies were eligible. Greater gain in clinical attachment (CA) (mean difference [MD]: 1.08 mm; p < 0.0001) and reduction in probing depth (PD) (MD: 1.05 mm; p < 0.00001) were observed for SRP + metronidazole (Mtz), and for SRP + Mtz + amoxicillin (Amx) (MD: 0.45 mm, MD: 0.53 mm, respectively; p < 0.00001) than SRP alone/placebo. Bayesian network meta-analysis showed additional benefits in CA gain and PD reduction when SRP was associated with systemic antibiotics. CONCLUSIONS: SRP plus systemic antibiotics led to an additional clinical effect compared with SRP alone in the treatment of AgP. Of the antibiotic protocols available for inclusion into the Bayesian network meta-analysis, Mtz and Mtz/Amx provided to the most beneficial outcomes.

Effects of smoking cessation on the outcomes of non-surgical periodontal therapy: a systematic review and individual patient data meta-analysis.

AIM: To conduct an individual patient data (IPD) meta-analysis to assess the effect of smoking cessation (SC) on clinical outcomes following the non-surgical periodontal treatment in patients with chronic periodontitis. METHODS: MEDLINE, EMBASE and CENTRAL were searched up to, and including, August 2012. Prospective cohort studies of at least 6 months' duration were included if the participants met the following criteria: (1) smokers who had expressed an interest in quitting the habit; and (2) a diagnosis of periodontitis. Search was conducted by two independent reviewers. IPD meta-analyses were undertaken using multiple linear or Poisson regression to evaluate the impact of SC on five different dependent variables. RESULTS: Of 2455 potentially eligible articles, two studies were included. The two studies found that SC seems to promote additional beneficial effects in reducing probing depths (PD) and improving attachment level following non-surgical periodontal treatment. The IPD approach allowed data combination but it might not have usefully added strength to the data in this review. CONCLUSION: SC seems to be an important component of periodontal therapy, and smokers should be encouraged to quit as part of their overall periodontal management; however, only a limited base of evidence was available for analysis.

Evidence-based periodontal plastic surgery. II. An individual data meta-analysis for evaluating factors in achieving complete root coverage.

BACKGROUND: The aim of this review is to conduct an individual patient data meta-analysis of randomized controlled clinical trials (RCTs) to evaluate whether baseline recession-, patient-, and procedure-related factors can influence the achievement of complete root coverage (CRC). METHODS: A literature search with no restrictions regarding status or the language of publication was performed for MEDLINE (for Medical Literature Analysis and Retrieval System Online), EMBASE (for Excerpta Medica Database), CENTRAL (for Cochrane Central Register of Controlled Trials), and the Cochrane Oral Health Group's Specialized Register databases up to and including March 2011. Only RCTs, with a duration of ≥6 months evaluating recession areas (Miller Class I or II) that were treated by means of root coverage procedures were included. Mixed-effects logistic regression analyses were conducted to evaluate associations between five baseline variables and CRC. RESULTS: Of the 70 potentially eligible trials, 22 were included in the meta-analyses. In total, the data from 320 patients and 16 procedures were evaluated. None of the RCTs were classified as low risk of bias. Of the 602 recessions treated, 310 (51.5%) achieved CRC. Subepithelial connective tissue grafts (SCTGs), matrix grafts, and enamel matrix derivative protein (EMD) procedures were superior in achieving CRC when compared to coronally advanced flap (CAF) alone. For the adjusted covariates, the greater the baseline recession depth, the smaller the chance of achieving CRC (individual procedure analysis [odds ratio (OR) = 0.55; 95% confidence interval (CI) = 0.44, 0.70] and grouped procedure analysis [OR = 0.56; 95% CI = 0.45, 0.71]), as well as studies with conflict of interest were more likely to achieve CRC than those without conflict of interest (individual procedure analysis [OR = 6.78; 95% CI = 1.78, 25.86]). CONCLUSIONS: SCTGs, matrix grafts, and EMD were superior to CAF in achieving CRC, but SCTGs showed the best predictability. The impossibility of inclusion of all identified RCTs should be taken into consideration when interpreting the present findings.

Stability of the factor structure of the metabolic syndrome across pubertal development: confirmatory factor analyses of three alternative models.

OBJECTIVE: To test the fit and stability of 3 alternative models of the metabolic syndrome's factor structure across 3 developmental stages. STUDY DESIGN: With data from the Fels Longitudinal Study, confirmatory factor analyses tested 3 alternative models of the factor structure underlying relationships among 8 metabolic syndrome-associated risks. Models tested were a 1-factor model (A), a 4-factor model (B), and a second-order latent factor model (C). Developmental stages assessed were prepuberty (ages 8-10), puberty (ages 11-15), and postpuberty (ages 16-20). RESULTS: Convergence was achieved for all developmental stages for model A, but the fit was poor throughout (root mean square error of approximation > 0.1). Standardized factor loadings for waist circumference and body mass index were much stronger than those for fasting insulin at all 3 time points. Although prepuberty and postpuberty models converged for models B and C, each model had problems with Heywood cases. The puberty model did not converge for either model B or C. CONCLUSIONS: The hypothetical structures commonly used to support the metabolic syndrome concept do not provide adequate fit in a pediatric sample and may be variable by maturation stage. A components-based approach to cardiovascular risk reduction, with emphasis on obesity prevention and control, may be a more appropriate clinical strategy for children and youth than a syndromic approach.

Standard operating procedures approach for the implementation of the evidence-based dentistry concept in dental practice.

Evidence-based dentistry is a concept that when applied to clinical practice may improve the quality of dental treatment. However, dentists' reluctance to change their behavior may be a barrier to the implementation of the process. The main purpose of this study was to demonstrate that standard operating procedures (SOPs) may help dentists to apply scientific evidence to their dental practice. SOPs are written instructions on how to execute some specific tasks. A flowchart model demonstrated how an ordinary clinical procedure (composite restoration) can be performed using evidence-based information to support each executed step. Implementing the model into daily practice is straightforward, and the results are accessible to the whole dental team. In addition, the flowchart can be regularly updated with high-quality dental literature such as systematic reviews of randomized controlled trials and randomized controlled trials. This proposed model may help to bridge the gap between research and clinical dental practice by serving as a practical tool to improve the knowledge of dental practitioners and the quality of treatment.
