Abstract
Although different studies suggest that early enteral nutrition (EEN) has benefits in reducing infectious complications, there is no data that addresses whether delayed enteral nutrition (EN) is detrimental and if it may have effects on inflammatory responses and immune function. Forty-five critically ill patients with long fasting were randomly allocated in two groups according to the type of nutritional support. The first group included patients assuming a standard enteral nutrition (EN, n = 22) and the second group assuming a parenteral nutrition (PN, n = 23). The daily nutritional amount was 25 kcal (105 kJ)/kg for all patients. The inflammatory markers white blood cells (WBC), C-reactive protein (CRP), TNF-α, IL-1-β, IL-6, IL-4, IL- 10 and the immune T-lymphocyte sub-populations CD3+, CD4+, CD8+, and HLA-DR+ were evaluated at day 1, and after 2, 3 and 7 days. IL-4, IL-10, CD3+, CD4+, CD8+ and the CD4+/CD8+ ratio were not statistically different between the two groups. WBC and TNF-α in EN patients were higher than those in PN after 3 and 7 days (P < 0.05). CRP and IL-6 levels were higher in EN patients than those assuming a PN after 2 and 3 days (P < 0.05). HLA-DR levels in patients assuming an EN were found higher than those in PN at day 7 (P < 0.05). Delayed EN for critically ill patients with long-term fasting increased systemic inflammatory responses, whereas EN could modify immune function, therefore reducing hospital stay and costs.

Abstract
BACKGROUND Scientific evidence on the effects of chronic periodontitis on diabetes mellitus remains inadequate and inconclusive. This intervention study is designed to evaluate the effects of periodontal treatment on clinical response, systemic inflammatory parameters, and metabolic control in patients with Type 2 diabetes. METHODS A total of 134 patients were randomly allocated into two treatment groups and one control group. Treatment group 1 underwent non-surgical periodontal treatment at baseline and additional subgingival debridement at the 3-month follow-up. Patients in treatment group 2 received non-surgical periodontal treatment and supragingival prophylaxis at the 3-month follow-up, and those in the control group received no intervention throughout the study. All participants were reexamined at 1.5, 3, and 6 months after initial treatment. At each visit, clinical periodontal examinations were conducted and blood samples were taken to evaluate high-sensitivity C-reactive protein (hsCRP), tumor necrosis factor-α (TNF-α), glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), and lipid profiles. RESULTS Both treatment groups had a significantly lower hsCRP level after periodontal therapy (P <0.05). Although HbA1c declined significantly in treatment group 2 (P <0.05), the intergroup difference for HbA1c, FPG, TNF-α, and lipid profiles was not statistically significant after therapy (P >0.05). CONCLUSIONS Non-surgical periodontal treatment can effectively improve periodontal and circulating inflammatory status. Despite a lack of strong evidence, trends in some results support improved glycemic control after periodontal treatment in patients with diabetes.
