Effect of Switching to the Tobacco Heating System Versus Continued Cigarette Smoking on Chronic Generalized Periodontitis Treatment Outcome: Protocol for a Randomized Controlled Multicenter Study.

Background: Smoking is a significant risk factor for periodontal disease and tooth loss, as shown in several clinical studies comparing smokers and nonsmokers. Although only a few longitudinal studies have assessed the outcome of periodontal disease after smoking cessation, they indicated that recovery after nonsurgical treatment was more successful in those who had quit smoking. As part of tobacco harm reduction strategies, substituting cigarettes with alternative, less harmful tobacco products is an approach complementary to cessation for smokers who would otherwise continue to smoke.

Influence of smoking and smoking cessation on levels of urinary 11-dehydro thromboxane B.

Background: Thromboxane is a key clinical risk endpoint of smoking-induced inflammation which has been associated in the pathogenesis of cardiovascular disease. The goal of this review is to quantify the effect of smoking and smoking cessation on one of its urinary metabolites, 11-dehydrothromboxane.

Methods: PubMed and SCOPUS were searched to identify publications which report urinary 11-dehydrothromboxane levels in smokers and non-smokers, as well as articles reporting the effect of smoking cessation on urinary 11-dehydrothromboxane excretion.

Physiologically Based Pharmacokinetic Modelling of Cytochrome P450 2C9-Related Tolbutamide Drug Interactions with Sulfaphenazole and Tasisulam.

Background And Objectives: Cytochrome P450 2C9 (CYP2C9) is involved in the biotransformation of many commonly used drugs, and significant drug interactions have been reported for CYP2C9 substrates. Previously published physiologically based pharmacokinetic (PBPK) models of tolbutamide are based on an assumption that its metabolic clearance is exclusively through CYP2C9; however, many studies indicate that CYP2C9 metabolism is only responsible for 80-90% of the total clearance. Therefore, these models are not useful for predicting the magnitude of CYP2C9 drug-drug interactions (DDIs).

Factors associated with stroke, myocardial infarction, ischemic heart disease, unstable angina, or mortality in patients from real world clinical practice with newly-diagnosed type 2 diabetes and early glycemic control.

Objectives: The objective of this study was to identify factors associated with stroke, myocardial infarction (MI), all-cause mortality, or a diagnosis of ischemic heart disease (IHD) or unstable angina (UA), among patients newly-diagnosed with type 2 diabetes (T2DM) with no recent history of cardiovascular (CV) events who rapidly achieve and maintain HbA ≤8.0%.

Methods: Data were obtained from the Clinical Practice Research Datalink (CPRD) from January 1990 to December 2012.

Evaluation of the effect of necitumumab on the corrected QT interval in patients with advanced solid tumors.

Purpose: Necitumumab is a second-generation, recombinant, human immunoglobulin G1 monoclonal antibody that blocks the ligand binding site of the epidermal growth factor receptor. The primary objective of this phase 2 study, conducted in accordance with International Conference on Harmonisation E14 guidance, was to determine the effect of necitumumab treatment on QT/QTc interval in patients with advanced solid tumors.

Methods: Patients received necitumumab monotherapy at an absolute dose of 800 mg, once per week for each 6-week cycle.

Effects of enzastaurin and its metabolites on the QT interval in cancer patients.

Preclinical and interim results from a clinical pharmacology study in patients with cancer indicated that enzastaurin might have the potential to prolong the QT. Rather than undertake a formal thorough QT study, the effect of enzastaurin on the QT was assessed by combining the QT corrected for heart rate (QTc) intervals from 3 clinical pharmacology studies totaling 85 patients with cancer receiving multiple therapeutic or supratherapeutic doses of enzastaurin. Neither a placebo nor an active control was used.
