Background: Tobacco smoke is toxic for cells and could be a damaging factor to skin. The purpose of this study was to compare the biophysical properties of skin in smokers and non-smokers.
Materials And Methods: The study population consisted of 28 current smokers and 24 non-smokers. The hydration of the stratum corneum, trans epidermal water loss, pH, erythema, melanin content, sebum, friction and elasticity parameters (R0, R2, R5) of skin, epidermis and dermis thickness and echo-density were measured on middle forehead, right cheek and right inner arm of participants. Also volume, surface area and depth of right nasolabial folds were measured. The mean of these values in smokers were compared with non-smokers by independent sample T- test.
Results: Gross elasticity was significantly lower in smokers on forehead (p= 0.048). Thickness of epidermis was higher in smokers in all measured sites but the differences were not statistically significant. Thickness of dermis was higher in smokers in all measured sites too, but only the difference on cheek was statistically significant (p= 0.009). Density of epidermis was lower in smokers in all measured sites, but only the difference on forehead was statistically significant (p= 0.019). Density of dermis was lower in smokers in all measured sites, but only the difference on arm was statistically significant (p= 0.028). Volume and area of nasolabial folds were higher in smokers, but only the difference of area was statistically significant (p = 0.031).
Conclusion: Tobacco smoking could affect the biophysical parameters of skin, especially thickness and density of dermis and epidermis and nasolabial folds.

Institute for Vascular Research, St. Franziskus Hospital, Münster, Germany.
Background: To compare the performance of a new-generation cobalt-chromium balloon-expandable bare metal stent with a stainless steel platform for the treatment of iliac occlusive disease.
Methods: Consecutive patients treated for symptomatic iliac occlusive disease between 2014 and 2021 with the cobalt-chromium Dynetic-35 or the stainless steel Dynamic platform were retrospectively evaluated. Outcome measures included technical success, device- or procedure-related death, clinically-driven target lesion revascularization (CD-TLR), primary patency, and major index limb amputation up to 12 months.

Background: As the primary cause of various preventable illnesses, smoking results in approximately five million premature deaths each year in the US and a multitude of adults living with serious illness. The majority of smokers know the health risks associated with smoking and intend to quit. However, quitting is very difficult partly because of insomnia and stress associated with it.

Introduction And Aims: We aimed to investigate the efficacy of air-polishing in restoring the original tooth colour of standardised tobacco-stained tooth specimens.
Methods: Seventy-two specimens consisting of half dentine and half enamel were daily exposed to the smoke of five cigarettes in an automated smoking chamber. Four repetitions of a 14-day smoking cycle were performed.

Diabetes and smoking are frequently co-morbid conditions leading to arterial insufficiency, significantly increasing the risk of non-healing wounds and subsequent major amputation. Autologous patient-specific mesenchymal stem cells (MSCs) present a novel tool for regenerative therapy to treat advanced stages of arterial insufficiency. The regenerative performance of cells from diabetics with impaired arterial perfusion is known to be reduced, but the impact of additional patient factors such as smoking remains poorly understood.

Background: Anemia is a prevalent comorbidity in COPD associated with increased morbidity. However, the significance of longitudinal anemia status and variation in anemia status trends over time in COPD are not known. Furthermore, individuals with COPD and smoking history often have multiple comorbidities, in particular cardiovascular disease.
