To evaluate the prevalence of smoking in patients who have suffered acute myocardial infarction with ST-segment elevation. Results: The findings of this study suggested that predictors of plaque erosion varied with different smoking status in patients with STEMI and broaden clinicians' understanding of clinical and lesion predictors of plaque erosion, especially in relation to smoking. Conclusion: In current smokers, diabetes mellitus was negatively associated with plaque erosion compared with plaque rupture. In nonsmokers, higher MLA and close bifurcation were positively related to plaque erosion, but not to plaque rupture. Compared to plaque rupture, the correlation between plaque erosion and current smoking complements clinicians' understanding of plaque erosion. There was a strong indication of the relationship between smoking and the development of STEMI.

Chronic pain is a prevalent condition worldwide and causes suffering, limited daily activities and reduced quality of life. There is growing evidence that COVID-19 infection is associated with myalgias, referred pain, and generalized hyperalgesia. The aim of the present study is to analyze the management of chronic pain during the COVID-19 pandemic. A systematic search was carried out in the Medline database. The following descriptors were used: "Pain Management" AND "coronavirus 2019" OR "SARS-CoV-2" OR "COVID-19" and "Pain" and articles on the topic published within the time frame (2019-2021) and in the English language. Telemedicine can help provide ongoing services to patients; assessments, treatment and follow-up. Patients with chronic pain may also be at increased risk for COVID-19 due to several factors. Important considerations for health professionals who care for people with chronic pain are: ensuring continuity of care and pain medications; use of telemedicine; maintenance of the biopsychosocial management approach; evaluation and safe conduction of urgent and semi-urgent procedures to avoid morbidity in patients with chronic pain; and the need to modify current therapies to decrease the risk of COVID-19.
