Smoking-related complications in foot and ankle surgery: a systematic review.
Eur Rev Med Pharmacol Sci
December 2024
Department of Orthopedic Surgery and Traumatology, Cantonal Hospital Fribourg, University of Fribourg, Fribourg, Switzerland.
Objective: The detrimental effects of cigarette smoking on overall health are well-documented, with nicotine and carbon monoxide contributing to peripheral vasoconstriction and impaired oxygen delivery to tissues. This study reviews the impact of smoking on wound and bone healing, specifically in foot and ankle surgery, given its significant role as a modifiable risk factor for complications in orthopedic procedures.
Materials And Methods: A systematic literature review was conducted in May 2024 following PRISMA guidelines.

Cigarette butts contain over 4000 toxic chemicals, including nicotine, tar, and heavy metals. More than 90 % of cigarettes sold today feature single-use plastic filters composed of cellulose acetate fibers and various additives. Cigarette butts are hazardous waste that pose significant risks to ecosystems and human health.

Article Synopsis
- - The study investigated how Lycium barbarum glycopeptide (LbGP) protects against bone loss caused by exosomes from human gingival fibroblasts damaged by radiation.
- - Results showed that radiation increased cell aging and apoptosis in fibroblasts, but LbGP treatment lowered these effects and improved cellular behavior in bone stem cells, promoting bone formation.
- - The findings suggest that LbGP could be a beneficial treatment for osteoradionecrosis of the jaw by reducing harmful osteoclast activity and enhancing bone healing.
Application of Hydroxyaromatic Aldehydes in Ultra-Efficient and Metal-Free Photocatalytic E→Z Isomerization of Olefin.
ChemSusChem
November 2024
Key Laboratory of Green Chemistry & Technology, Ministry of Education, College of Chemistry, Sichuan University, Chengdu, 610064, P. R. China.
Article Synopsis
- The study focuses on a new method for converting E-olefins to Z-alkenes using photocatalysis, specifically with hydroxyaromatic aldehyde as a sensitizer under blue light.
- The process is quick and highly efficient, achieving a Z/E ratio of 92:8 in just 5 minutes, and can be scaled up successfully while showing reactivity towards various olefin derivatives.
- This metal-free method is advantageous due to its efficiency, convenience, lack of by-products, and high selectivity, with insights into its underlying mechanism linked to the sensitizer's triplet energy.
Health risks of environmentally persistent free radicals in atmospheric particulate matter during the spring festival travel season in Tainan, Taiwan.

Environmentally persistent free radicals (EPFRs) and polycyclic aromatic hydrocarbons (PAHs) are persistent pollutants in atmospheric particulate matter that are detrimental to human health. This study collected atmospheric particulate matter during and after the spring festival travel season in Tainan, Taiwan, from various locations and analyzed the carbon composition and PAH isomeric ratios to identify the sources. In this study, EPFR concentrations were measured using electron paramagnetic resonance spectroscopy, with the highest concentration found to be 3.
