The data presented demonstrate a functional linkage between AM and NO in periodontal disease, with salivary and gingival crevicular fluid levels possibly associated with different forms and severities of periodontal disease. Exacerbated production of both AM and NO in saliva suggests their potential use as salivary markers of aggressive periodontitis.
This study highlights the strong association of different types of ST and oral cancer. This results in identification of high-risk groups for targeted screening for potential oral cancer lesions.
Pathogens associated with aggressive periodontitis, A. actinomycetemcomitans and C. rectus, were more effective than those associated with chronic periodontitis, P. gingivalis and Prev. intermedia, and commensals, S. salivarius and V. atypica, as regards the upregulation of AM and NO production from oral keratinocytes. Interaction between these molecules was also demonstrated with macrophages. Understanding the coordinated regulation of AM and NO production in response to periodontal bacteria may identify ways to promote their protective effects and minimize destructive potential.
This article presents the systematic review of the randomized, controlled trials comparing the effectiveness of nasogastric (NG) versus postpyloris (PP) feeding in critically ill surgical patients and other patients in intensive therapy unit (ITU). Twenty randomized trials recruiting 1496 patients were retrieved from the standard electronic databases. There were 760 patients in the NG feeding group and 736 patients in the PP feeding group. There was significant heterogeneity among trials. PP feeding in ITU patients was associated with lower gastric residual volume (odds ratio (OR), 3.95; 95% confidence interval (CI), 1.19, 13.14; z = 2.24; P<0.03; I(2) = 73%) and a reduced risk of developing aspiration pneumonia (OR, 1.41; 95% CI, 1.01, 1.98; z = 2.03; P<0.04; I(2) = 10%) compared with NG feeding. In addition, higher proportion of caloric requirements (standardized mean difference, -1.02; 95% CI, -1.73, -0.31; z = 2.82; P<0.005; I(2) = 95%) could be delivered with PP feeding. Risk of gastrointestinal complications, overall mortality and length of ITU stay were similar between the two techniques of enteral feeding. In summary, PP feeding in ITU patients reduces the gastric residual volume and risk of aspiration pneumonia. PP feeding is also superior to NG feeding in terms of delivering higher proportion of daily caloric requirements. PP feeding with the help of nasoduodenal or nasojejunal tube may be used routinely in ITU patients for nutritional support.
Application and implementation of measures outline in the MPOWER package, formulation and enforcement of sturdy laws on tobacco control, and development of infrastructure and trained workforce are fundamental to manage and reinforce tobacco control measures in the GCC region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
