Smokers

This study compares the different effects of traditional cigarettes, e-cigarettes, and narghile on periodontal health among a sample of Al-Hawash Private University students. The main question it aims to answer is: Are there statistically significant differences in periodontal parameters among different types of smokers?

The aim of the study is to evaluate how a gel (1.2% lovastatin) applied under the gum improves the results of classic periodontal treatment (SRP-scaling, root planing). The study involves two groups of adults diagnosed with periodontitis: the first group consists of generally healthy individuals who do not smoke tobacco. The second group consists of generally healthy individuals who have been smoking for at least 5 years. Before the study begins, each participant will undergo gum health measurements. Changes in these parameters will be monitored throughout the study. Two teeth will be selected for each participant: * a gel containing the medication will be applied under the gum of one tooth * a gel that looks similar to the medication but does not contain any medicinal substance will be applied under the gum of the second tooth. Before applying the gel, each participant will undergo subgingival cleaning (SRP) to remove any debris that may prevent the medicine from working. The study will last six months. Expected results: * all participants will experience an improvement in the condition of their gums after treatment * the effect of treatment will be better in non-smokers than in smokers * the treatment outcome will be better in the area where the medicated gel was applied compared to areas where the gel without medicinal substances was applied.

This is a study assessing the feasibility of performing an anti-aging intervention which is a combination of an exercise regimen, spermidine supplementation, and either rapamycin or lamivudine.

Chronic Obstructive Pulmonary Disease (COPD), , secondary to smoking, is a major public health issue with very high direct and indirect costs. The impact on the health system of undiagnosed patients, up to 70% of patients, is increasingly documented. However, systematic spirometry screening remains controversial among smokers in the absence of data to link the detection of new patients with improved management and clinical events and health goals. More generally, there is little data on the evolution of patients in real life once they have entered the care system. The premise is that with systematic screening in general medicine, it is possible to identify the evolution of newly diagnosed COPD patients, to distinguish the different possible evolutions according to the initial phenotype and the management.
