Randomized Trial to Test a Chemo-Mechanical Antiplaque Regimen as Adjunct to Periodontal Therapy.

Background: The control of dental biofilm regrowth after nonsurgical periodontal therapy is associated with better clinical outcomes. However, many patients have difficulty achieving optimal plaque control. Subjects with diabetes, in which immune and wound-healing responses are typically impaired, may benefit from intensive antiplaque control regimens after scaling and root planing (SRP).

Periodontal disease is associated with increased gut colonization of pathogenic Haemophilus parainfluenzae in patients with Crohn's disease.

Intestinal colonization of the oral bacterium Haemophilus parainfluenzae has been associated with Crohn's disease (CD) severity and progression. This study examines the role of periodontal disease (PD) as a modifier for colonization of H. parainfluenzae in patients with CD and explores the mechanisms behind H.

Using Intervention Mapping to Develop a Theory-Based Intervention to Promote Colorectal Cancer Screening in Egypt.

Background: Colorectal cancer (CRC) incidence and mortality rates are increasing in Egypt. Because no national screening guidelines exist, developing an effective evidence-based screening intervention could lower rates by early detection of pre-cancerous and cancerous lesions and polyps. This paper describes the development of a CRC screening intervention in Alexandria, Egypt using Intervention Mapping (IM).

Modelling the emergence dynamics of the western corn rootworm beetle (Diabrotica virgifera virgifera).

The western corn rootworm is an invasive species to Europe and is a major agricultural pest that causes widespread economic and yield losses to maize producers. The Gompertz curve was originally used to model human population mortality. It is a sigmoidal curve where the beginning and end of a period shows the slowest time for growth, and adequately describes observed dynamics of many phenomena.

Porphyromonas gingivalis indirectly elicits intestinal inflammation by altering the gut microbiota and disrupting epithelial barrier function through IL9-producing CD4 T cells.

Recent epidemiological studies have shown that inflammatory bowel disease is associated with periodontal disease. The oral-gut microbiota axis is a potential mechanism intersecting the two diseases. Porphyromonas gingivalis is currently considered a keystone oral pathogen involved in periodontal disease pathogenesis and disease progression.
